Description
Technical field
The utility model belongs to machine-building special fixture, particularly a kind of special fixture of pump case part Boring.
Background technology
Boring just refers to and is carried out expanding or refining in hole original on workpiece, its feature revises the bias of lower opening, obtains the position in accurate hole, obtain high-precision circularity, cylindricity and surface smoothness, so Boring is often used in last operation as a kind of high accuracy processing method.Such as, but for the part of some shape uniquenesses, implement Boring and must coordinate special boring jig, the processing of pump case class part just needs to use special fixture.But pump case special fixture of the prior art, mostly complex structure, manufactures, use cost is higher, be unfavorable for applying on a large scale.
Summary of the invention
The purpose of this utility model is the special fixture providing a kind of pump case part Boring, to improve its working (machining) efficiency.
To achieve these goals, the utility model provides following technical scheme: a kind of special fixture of pump case part Boring, comprise clamp body, described clamp body upper surface is horizontal plane, and this end face is provided with the alignment pin for coordinating with the datum hole of pump case, described alignment pin is vertically arranged, and described alignment pin is provided with axially extending bore; Described clamp body is also provided with stud, described stud lower end and clamp body affixed, stud is through the through hole on alignment pin and extend to alignment pin upper end, and described stud upper end is provided with packing ring and nut, described packing ring is pressed on aperture, the upper end end face of the datum hole of pump case, and described nut is pressed on packing ring; The ear seat for connecting boring table is provided with bottom described clamp body;
The upper surface of described clamp body is also provided with cushion block, and described cushion block is tabular, and described cushion block center is provided with the circular hole passed for alignment pin, and described cushion block is fixed by screw and clamp body;
The upper surface of described clamp body is provided with blind hole, and described alignment pin is inserted in this blind hole and the two forms interference fit;
Described ear seat edge is provided with for bolted U-type groove.
Technique effect of the present utility model is: the utility model is applicable to the mode that need repeat to load and unload frock when multiple product is produced, quick despatch can be realized, the loss of spare and accessory parts and equipment can be reduced again, improve the working (machining) efficiency of valve body piece, and structure is simple, easy to loading and unloading, economical and practical, be suitable for promoting.

Detailed description of the invention
As shown in Figure 2,3, a kind of special fixture of pump case part Boring, comprise clamp body 10, described clamp body 10 upper surface is horizontal plane, and this end face is provided with the alignment pin 11 for coordinating with the datum hole 21 of pump case 20 shown in Fig. 1, described alignment pin 11 is vertically arranged, and described alignment pin 11 is provided with axially extending bore; Described clamp body 10 is also provided with stud 12, described stud 12 lower end and clamp body 10 affixed, stud 12 passes the through hole on alignment pin 11 and extends to alignment pin 11 upper end, described stud 12 upper end is provided with packing ring 14 and nut 13, described packing ring 14 is pressed on aperture, the upper end end face 22 of the datum hole 21 of pump case 20 shown in Fig. 1, and described nut 13 is pressed on packing ring 14; The ear seat 17 for connecting boring table is provided with bottom described clamp body 10.Alignment pin of the present utility model 11 pairs of pump cases 20 carry out radial location, packing ring 14 pairs of pump cases 20 carry out axial location, because boring process belongs to revolution processing, therefore without the need to carrying out circumference location, only need to ensure in process that pump case 20 does not produce to rotate, as long as and nut 13 compresses and just can ensure that pump case 20 is circumferential and fix.
Further, the upper surface of described clamp body 10 is also provided with cushion block 15, described cushion block 15 is in tabular, and described cushion block 15 center is provided with the circular hole passed for alignment pin 11, and described cushion block 15 is fixed by screw 16 and clamp body.Cushion block 15 can limit the position, lower surface of pump case 20, and can be adapted to the process requirements of different model pump case 20 by the cushion block 15 changing different-thickness.
Preferably, the upper surface of described clamp body 10 is provided with blind hole, and described alignment pin 11 is inserted in this blind hole and the two forms interference fit.Because the dimension precision requirement of alignment pin 11 is higher, therefore need independent processing, and then assemble with clamp body 10.
Preferably, described ear seat 17 edge is provided with for bolted U-type groove 18.Boring table generally adopts inverted T shape groove and bolt to fix fixture, and bolt head to be stuck in inverted T shape groove and can to slide along T-slot.The utility model offers U-type groove 17 on ear seat, in the process of remover-and-replacer, only the clamp nut on bolt need be unscrewed a little and just bolt can be skidded off or slip into U-type groove 17, thus realize fast assembling-disassembling.
