The special-shaped part of the piston die casting is provided with a through hole, the position of the through hole is matched with that of the threaded hole in the platform part when the bottom face part butts against the supporting screws, the fastening screw penetrates through the through hole and is connected with the threaded hole in the platform part, and the piston die casting is clamped and fixed above the fixture body. Through the application of the special fixture for the piston die casting, the problem of the clamping of products in a traditional machining scheme is solved effectively, and the fixture is simple in operation, high in machining efficiency, capable of improving the rate of finished products and the quality of the finished products greatly and suitable for mass production occasions.
Description
Technical field
The utility model relates to a kind of industrial processes fixture, relates in particular to a kind of specific aim and carries out firm clamping for piston die casting, carries out the special fixture of turning operation, belongs to mechanical manufacturing field.
Background technology
In to the machining of general industry part, especially, in turning processing, need to carry out to part to be processed the clamping location of high accuracy, high stability.Prior art is when lathe machining piston part, what adopt is twice cylindrical clamping scheme, due to the restriction of piston details product structure and size, first adopts one end of scroll chuck clamping piston details cylindrical, realize to foreign round part processing, the other end again turns around to process after completion of processing.Because clamping amount is less, easily distortion and centering precision are low, and twice clamping increases axiality and the deviation from cylindrical form of piston details, and production efficiency is low, and percent defective is higher.
Summary of the invention
Particularity in view of above-mentioned piston details shape, the purpose of this utility model is the special fixture that proposes a kind of piston die casting, so that part product to be processed can keep the stability of relative lathe tool and lathe when the high strength processing operation such as cutting, thereby improving production efficiency and product quality.
The purpose of this utility model, will be achieved by the following technical programs:
A kind of special fixture of piston die casting, described piston die casting has the special-shaped portion of discoidal bottom surface sections and the irregular shape of bottom surface sections one side, it is characterized in that: described special fixture comprises clamp body, a trip bolt and two supporting screws, the surface configuration that described clamp body mates special-shaped portion is provided with platform part and sagging chamber portion, described platform part is provided with the screw that trip bolt is installed, and be spirally connected in the side over against piston die casting bottom surface sections two supporting screws be outer dewiness of clamp body; Piston die casting abnormity portion is provided with that location matches is in the perforation of platform part screw when bottom surface sections and supporting screw connect, and trip bolt sees through perforation and joins with clamp body platform part screw, and piston die casting is clamped on clamp body.
Further, a described trip bolt and two supporting screws are countersunk head soket head cap screw.
Practicing of the utility model special fixture, efficiently solves the problem that traditional processing proposal product clamping exists.This fixture operation is simple, and working (machining) efficiency is high, and yield rate and end product quality improve greatly, is suitable for the occasion of batch production.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.
Accompanying drawing explanation
Fig. 1 is the side-looking structural representation of the utility model clamp body;
Fig. 2 is the plan structure schematic diagram of clamp body shown in Fig. 1;
Fig. 3 is the side-looking structural representation of piston die casting;
Fig. 4 is the plan structure schematic diagram of the die casting of piston shown in Fig. 3;
Fig. 5 is that piston die casting and special fixture complete the side-looking structural representation after clamping.
The specific embodiment
In view of the peculiar part shape of piston die casting, the utility model designer has concentrated on studies the clamp structure of this type of part has been designed, and innovation has proposed a kind of special fixture of piston die casting.
As shown in Figures 1 to 5, this piston die casting 2 has the special-shaped portion 22 of discoidal bottom surface sections and the irregular shape of bottom surface sections one side, and in some situation, this abnormity portion 22 can separate outer male structure based on main body plane area.For the part of this species specificity shape, as special fixture, need to comprise clamp body 1, trip bolt 3 and two supporting screws 4, the surface configuration of this clamp body 1 special-shaped portion of coupling is provided with platform part 11 and sagging chamber portion 12; In addition, this clamp body 1 is provided with screw 13, and this obform body 22 is provided with when bottom surface sections and top brace part connect that location matches is in the perforation 21 of screw 13, and trip bolt 3 sees through perforation 21 and joins with screw 13, and piston die casting 2 is clamped on clamp body 1.Wherein this trip bolt 3 can be countersunk head soket head cap screw, can be also other screw with special spiral shell header structure.
And this clamp body 1 is provided with 14, two supporting screws 4 of two positioning screw holes and is spirally connected respectively and is positioned wherein and exposes to side over against the side of piston die casting bottom surface sections, form the top brace part of this special fixture.This top brace part exposes to the distance d of side for forming according to the accurate calculating of the dimensional requirement of piston die casting grinding.When piston die casting clamping, mainly play a part shore and locate.This two supporting screw 4 can be countersunk head soket head cap screw, can be also other screw with special spiral shell header structure.
When carrying out product clamping, first two supporting screws 4 are spirally connected and are fixed on clamp body, and reach desired positioning precision through grinding.Piston die casting positions by two supporting screws and clamp body, and by trip bolt 3, seeing through perforation 21 joins with screw 13, be positioned on clamp body 1 piston die casting 2 is clamping, thereby realize, limit its free degree in all directions, be axial translation freedoms and rotary freedom etc., be convenient to thus the high-precision turning processing of product.
In addition to the implementation, the top brace part of the utility model special fixture can also be over against the side one of piston die casting bottom surface sections, to extend the support column being convexly equipped with by clamp body, and support column exposes to side.But this way compares to above-described embodiment lacks flexibility on top brace part height d.
Practice as seen in sum special fixture of the present utility model, can efficiently solve the problem that traditional processing proposal product clamping exists.This fixture operation is simple, and working (machining) efficiency is high, and yield rate and end product quality improve greatly, is suitable for the occasion of batch production.
