Content of a design knows, choose the surface on gear-box body, a flank and an end panel are fixed position datum plane, restrict 3 freedom of workpiece to spend respectively, two freedom are spent and a freedom is spent. Among them, the surface is datum plane of main fixed position on. Of component of ㈡ fixed position choose: Wait for an element according to the dimension of casing, the surface locates component chooses 3 backing plate on, when clamping apparatus body is installed, assure face of fixed position of 3 backing plate to wait tall, restrict 3 freedom of casing to spend. Basis " course of design of mechanical production equipment is designed " subordinate list of the 151st page 3.

3, choice backing plate is: 220 JB/T8029 of × of backing plate B25.

1-1999, if its diagram pursues 1, if dimension parameter expresses 1 to show: Graph diagram of 1 backing plate expresses Kong Shu of Adhh1 of ι of HLBb of 1 dimension parameter 25220402030801372.

53 note: Outside Kong Shu is being divided in the watch, unit of the others measurement all is Mm. Lateral locates component chooses bearing hammer, restrict a freedom of casing to spend. Basis " course of design of mechanical production equipment is designed " subordinate list of the 150th page 3.

2, choice backing plate is: Bearing nails A16 × 8 JB/T8029.

2-1999, if its diagram pursues 2, if dimension parameter expresses 2 to show: Graph diagram of 2 bearing hammer expresses R61682010+0 of extreme deviation of basic measure of DHLd of 2 dimension parameter.

019 note: Unit of the measurement in the watch all is Mm. The end panel of gear-box body is treatment surface, accordingly, the orientation way of end panel should choose to be the fixed position bearing of mobile type. Of gear-box body on the surface and lateral fixed position had restricted 4 freedom to spend, the basis located at 6 o'clock principle, the fixed position of end panel needs to restrict two freedom of gear-box body to spend. Fixed position component chooses two bearing hammer, the fixed position plane that makes sure two bearing are nailed when installation is on same plane. Bearing hammer model and side fixed position nail model with bearing identical, for: Bearing nails A16 × 8 JB/T8029.

2-1999, if dimension parameter expresses 2 to show. Its sketch map is shown 2 times like the graph. Clamp answers commonly after plan of clamp of Nextpage2 certain work and work of unit of design choice clamp locate correctly in clamping apparatus, make workpiece maintains acquired fixed position to be not destroyed in machining a process. The principle that when clamp orgnaization designs, should satisfy is as follows: The place that workpiece is locating the place on component is obtained cannot be destroyed when ㈠ clamp; ㈡ clamping force should assure work place changeless in whole treatment process or do not produce unallowed vibration; ㈢ makes workpiece has not arisen to be out of shape greatly injure with the surface; ㈣ clamp orgnaization must reliable; ㈤ clamp orgnaization is operated must safe save labour, convenient, accord with an individual to operate a habit; The complex degree of ㈥ clamp orgnaization and automation degree must suit with production program and plant requirement photograph. Clamp nods the general principle of the choice: ㈠ makes clamp dot and bearing point opposite as far as possible should, make clamping force action is on bearing; The option that ㈡ clamp chooses should near treatment surface as far as possible, and the choice is in do not send had caused big metabolic position. Follow afore-mentioned principles, the place that affirmatory clamp chooses approachs point of two end panel in casing underside, with go up fixed position backing plate of the surface is opposite. There is one to manage fixed position in end panel place, restrict a freedom of gear-box body to spend, and in machining a process, casing suffers strength is as relative as its, reason need not bring to bear on again clamping force. Referenced " design manual of practical and mechanical workmanship " clamping unit of choice of 14-20 of watch of the 331st page is hook form pressing plate, model is: 55 JB/T8012 of × of pressing plate A17.

1-1999. Its diagram is shown 3 times like the graph, if dimension parameter expresses 3 to show: Graph parameter of dimension of 3 pressing plate expresses H1113453530-0 of extreme deviation of basic measure of F9 of extreme deviation of basic measure of D1ABDHhrr1d2h1h2 of 3 dimension parameter.

4 designs content knows: Dimension of the T of milling machine workbench chamfer is: 5-18 × 105 (groovy number - slot pitch of groovy wide × ) . Check accordingly " design manual of practical and mechanical workmanship " the 319th page expresses 14-15, the choice locates key is: A18h6 JB/T8016-1999 of fixed position key. Its sketch map is shown 4 times like the graph, if dimension parameter expresses 4 to show: Graph sketch map of key of 4 fixed position expresses suitable bolt of BLHh1dd1 of 4 dimension parameter H6180 -0 of basic measure extreme deviation.

Body of clamping apparatus of design of style of 5 clamping apparatus is the matrix of whole clamping apparatus and framework. All sorts of parts that form clamping apparatus and orgnaization, want installation to be above clamping apparatus body, its appearance and dimension basically depend on each are comprised on clamping apparatus the appearance of distributinging circumstance and workpiece, dimension and fabricating characteristics. Integrated consideration machines function, intensity, stiffness and economy to wait, body of affirmatory clamping apparatus is cast, material is HT200. The specific figure size of clamping apparatus body sees part drawing of clamping apparatus body. CNC Milling
