AI Technical Summary
When conventional clamps are used to clamp the pump body, the matching degree is low, resulting in slight shaking and rotating displacement of the pump body, resulting in steel column pressure deviation and defective products, and the yield rate is low.
A pump-body tooling fixture is designed, including brackets, bearing seats, threaded columns, lifting tables and elastic clamps. By placing the pump body on the lifting platform, rotating the threaded column, pulling the lifting platform downward, so that the elastic clamp slides into the bracket, and clamping the elastic clamp is used to clamp the elastic clamp with the internal force of the bracket, thereby fixing the pump body, limiting its 5 degrees of freedom, and improving clamping stability.
By limiting the 5 degrees of freedom of the pump body, the clamping stability is significantly improved, thereby greatly improving the yield of pump body assembly and reducing the generation of defective products.

Description
Technical Field
[0001] The utility model belongs to the technical field of pump body processing equipment, and particularly relates to a pump body tooling fixture. Background Technique
[0002] When processing a pump body, a fixture is needed for fixation. A fixture refers to a device used in the mechanical manufacturing process to fix a processing object, make it occupy the correct position, and accept construction or inspection, also known as a jig. Generally speaking, any device used to quickly, conveniently, and safely install a workpiece in any process of the technological process can be called a fixture.
[0003] Due to the relatively low matching degree between the conventional fixture and the pump body, after directly clamping the pump body, the pump body has a small amplitude of shaking, there is vibration when the cylinder press head presses down, which is likely to cause the pump body to rotate and displace. After the steel column is pressed offset, defective products are formed, resulting in a relatively low qualified rate of using the conventional fixture to clamp the pump body.
[0004] Therefore, we propose a pump body tooling fixture to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem of relatively low qualified rate of using the conventional fixture to clamp the pump body, and to propose a pump body tooling fixture.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A pump body tooling fixture includes a bracket, a bearing seat is fixedly connected to the bracket, a threaded column is rotatably connected inside the bearing seat, a lifting table is threadedly installed on the upper part of the threaded column, the lifting table is slidably installed inside the bracket, and an elastic clamping plate is fixedly connected to the outer periphery of the lifting table. Place the pump body on the lifting table, rotate the threaded column, pull the lifting table downward through the threaded column, so that the lifting table pulls the elastic clamping plate downward, and the elastic clamping plate slides into the bracket. Use the bracket to act on the elastic clamping plate inward to clamp and fix the pump body; by restricting 5 degrees of freedom of the pump body, the clamping stability is improved, thereby greatly improving the qualified rate of pump body assembly.
[0008] Preferably, a mounting seat is fixedly connected to the lower end of the bracket. The device can be conveniently installed on the target tabletop by means of screws through the mounting seat.
[0009] Preferably, the bearing seat includes a connecting block and a bearing, and the connecting blocks are symmetrically and fixedly connected to the upper end of the bearing. The bearing facilitates guiding the rotation of the threaded column.
[0010] Preferably, the threaded post includes a threaded post body, a first retaining ring, and a second retaining ring. The second retaining ring and the first retaining ring are fixedly connected to the outer end of the lower part of the threaded post body. By screwing the second retaining ring to drive the threaded post body to rotate, the lifting table is driven to lift and lower by the threaded post body, which facilitates the threaded post to control the lifting and lowering of the lifting table.
[0011] Preferably, the threaded post further includes an operating disk, and the operating disk is fixedly connected to the outer end of the second retaining ring. Using the operating disk to increase the length of the manual operation lever facilitates the manual operation of rotating the second retaining ring.
[0012] Preferably, the lifting table includes a tubular table and a threaded block, and the lower end of the tubular table is fixedly connected to the upper end of the threaded block. When the threaded post rotates, the threaded block is lifted and lowered along the bracket, which facilitates the lifting and lowering of the lifting table along the bracket.
[0013] Preferably, the elastic splint includes a plate body, a leather block, and a spring piece. The plate body and the spring piece are fixedly connected as a whole, and the leather block is fixedly connected to the upper part of the plate body. When the plate body enters the bracket, the bracket acts on the plate body inward, causing the plate body to drive the leather block to clamp towards the target pump body, which facilitates the elastic splint to clamp and fix the target pump body after contraction.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:
[0015] 1. Place the pump body on the lifting table, screw the threaded post to rotate, pull the lifting table downward through the threaded post, so that the lifting table pulls the elastic splint downward, causing the elastic splint to slide into the bracket. The bracket acts on the elastic splint inward to clamp and fix the pump body; by restricting 5 degrees of freedom of the pump body, the clamping stability is improved, thereby greatly improving the yield rate of pump body assembly.
[0016] 2. Screw the second retaining ring to drive the threaded post body to rotate, and drive the lifting table to lift and lower through the threaded post body, which facilitates the threaded post to control the lifting and lowering of the lifting table.
[0017] 3. When the plate body enters the bracket, the bracket acts on the plate body inward, causing the plate body to drive the leather block to clamp towards the target pump body, which facilitates the elastic splint to clamp and fix the target pump body after contraction.
