Specific embodiment
The present invention is further detailed explanation with concrete better embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of fixture for valve seat conical surface coating, including revolvable main shaft 1 be fixedly installed on master
The indexing slewing equipment 2 on axle 1 top.Main shaft 1 is preferably fixed on the base 12 of built-in motor, and indexing slewing equipment 2 can be
Many indexing reversing frames, six decile reversing frames as shown in Figure 1 or index rotary disk one more.
The built-up jig body of several energy rotations is evenly arranged with the top circumference of indexing slewing equipment 2.As Fig. 1 institute
Show, the top of six supports of six decile reversing frames is respectively provided with a built-up jig body, has 6 built-up jigs altogether
Body.
As shown in Figures 2 and 3, each built-up jig body all includes the vertical shaft 3 of energy rotation and is set in vertical shaft 3 periphery
And the plating carbon installing rack 4 of the cylinder that can rotate with vertical shaft 3.Wherein, every vertical shaft 3 is all paralleled with main shaft 1, every vertical shaft 3
All equal with the distance between main shaft 1.So, during coating processing, can guarantee that the frequency of rotation or revolution is consistent, coating uniform
Adhesion performance of property and coating etc. also all can be guaranteed.
Each plates and is evenly arranged with several hanger bodies 6 in the circumference of carbon installing rack 4, preferably 16.Each hanger body 6
Preferably be and be detachably connected with plating carbon installing rack 4, so can facilitate the clamping of workpiece to be processed (i.e. the valve seat conical surface, similarly hereinafter) with
Dismounting, coating processing when, can first workpiece to be processed be put in each hanger body 6, then by hanger body 6 successively with plating carbon installing rack
4 are installed, and improve the working (machining) efficiency of coating.
As shown in Fig. 3, Fig. 4 and Fig. 5, each hanger body 6 all includes the strip matrix 7 being fixedly connected with plating carbon installing rack 4
With the cover plate 9 being arranged at strip matrix 7 outside.Wherein, each strip matrix 7 is evenly arranged with several be used for placing to be added
The fixture hole 8 of work workpiece, is preferably provided with 25 fixture holes 8.As shown in fig. 6, several and folder are provided with each cover plate 9
The corresponding punched out 10 in tool hole 8 position.During clamping, first several workpieces to be processed are put in corresponding fixture hole 8, then
Clamped using cover plate 9 and seal.This cover plate 9 clamps the design of workpiece, both ensure that simple operation performance during clamping workpiece,
Increased clamping quantity, can guarantee that workpiece to be processed is not required to plate the sealing at carbon coating position again, so that coating location is accurately,
Passing rate of processing is high.
In addition, the fixture hole 8 on each above-mentioned hanger body 6 is preferably homogeneously intercommunicated, after workpiece to be processed is put into, mutually
The cavity volume of vacuum can be formed inside the fixture hole 8 of connection.During clamping, can first processing workpiece be put in corresponding fixture hole 8 simultaneously
Clamped with cover plate 9, unification afterwards carries out vacuum pumping with vacuum extractor, thus it is possible, on the one hand, further ensuring hanger body 6
Sealing it is therefore prevented that be not required to coating plate carbon position by by mistake coating so that coating location is accurately, fraction defective reduces.Another
Aspect, makes the weight reduction of hanger body 6, easy to setup.
Further, as shown in figure 3, each above-mentioned plating carbon installing rack 4 all includes being set in the sleeve 11 of vertical shaft 3 periphery and consolidates
Surely it is arranged at the autorotation disk 5 of sleeve 11 upper and lower ends, each autorotation disk 5 is all detachably connected with vertical shaft 3, each hanger body 6 is equal
It is fixedly connected with autorotation disk 5 and sleeve 11.Due to there being gap between sleeve 11 and vertical shaft 3, only upper and lower two autorotation disks 5 and vertical shaft
3 are fixedly connected, thus alleviating the deadweight of plating carbon installing rack 4, namely the deadweight alleviating the application fixture.
In addition, being the cleannes ensureing fixture intracavity and workpiece to be processed, the application fixture is all using 304 stainless steels
Make.
When the application fixture uses, need first to carry out clamping to workpiece to be processed, the application once being capable of clamping 2000-3000
Part workpiece to be processed.After the completion of clamping, each built-up jig body presses set angle rotation, so as to make positioned at this built-up jig body
All workpieces to be processed on interior all hanger bodies 6 carry out coating operation.After a built-up jig body completes coating operation, main
Axle 1 is pressed set angle and is revolved round the sun once, switches to another one built-up jig body, then the rotation of built-up jig body and main shaft 1 revolve round the sun
Circulate successively, thus completing the coating operation of each built-up jig body.
