Description

Technical Field

[0001] This utility model relates to the field of pump body processing structure technology, specifically a pump body clamp. Background Technology

[0002] The volutes of small and medium-sized centrifuges currently in use mainly consist of a volute body and a volute horn integrated with the volute body. The horn of the volute is equipped with a flange. The volute body usually has another plane parallel to the flange plane on the volute horn. In this way, during CNC machining, this plane and the flange plane on the volute horn can be used as references to accurately position and reliably fix the volute, thereby completing the corresponding machining operations.

[0003] During the current pump body processing, the pump body shell needs to be clamped and positioned. However, when processing a volute-shaped pump body, the fixing structure on the outside of the pump body is prone to slippage during processing, which leads to defects in the shell processing, increases the amount of burrs in the shell processing, and reduces the stability and forming accuracy of the pump body processing.

[0007] Preferably, the three sets of support blocks are provided with anti-slip texture on the outer side, and the three sets of support blocks are distributed on the top of the mounting base near the outer side of the tensioning and centering clamp to improve the stability of the pump body support.

[0011] The pump body clamp proposed in this utility model has at least the following beneficial effects:

[0012] With the tensioning and positioning of the tensioning and centering fixture and the cooperation of three sets of clamping structures, the volute pump body is fixed on the surface of the machining table.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5The present invention provides an embodiment of a pump body clamp, comprising a mounting base 1. The top of the mounting base 1 includes a first cylinder 5, a second cylinder 8, and a third cylinder 9. The output end of the first cylinder 5 is provided with a first clamping block 6, the output end of the second cylinder 8 is provided with a second clamping block 7, and the output end of the third cylinder 9 is provided with a third clamping block 10. The top of the mounting base 1 is provided with multiple sets of grooves. The first cylinder 5, the second cylinder 8, and the third cylinder 9 are disposed inside the grooves to facilitate the installation and fixation of the structure. The clamping surfaces inside the first clamping block 6, the second clamping block 7, and the third clamping block 10 are provided with anti-slip textures to improve the fixing effect of the clamping components.

[0021] A tensioning and centering fixture 11 is provided at the middle position of the mounting base 1. The processing pump body 2 is placed on the top of the tensioning and centering fixture 11. The bottom of the tensioning and centering fixture 11 is provided with interconnected lifting cylinders 13. Three sets of support blocks 12 are provided at the middle position of the top of the mounting base 1. The outer side of the three sets of support blocks 12 is provided with anti-slip texture. The three sets of support blocks 12 are distributed on the top of the mounting base 1 near the outer side of the tensioning and centering fixture 11 to improve the stability of the pump body support. An adjusting seat 4 is provided on one side of the top of the mounting base 1, and a side pressure positioning block 3 is provided on one side of the adjusting seat 4. The side pressure positioning block 3 is in contact with the outer side of the processing pump body 2. A central shaft positioning plate is provided on the top of the tensioning and centering fixture 11 to facilitate the centered placement and positioning of the pump body.

[0022] In Example 1, the adjusting seat 4 includes an adjusting cylinder and a movable shaft. The output end of the adjusting cylinder is connected to the side pressure positioning block 3. The side pressure positioning block 3 is located inside the movable shaft. By adjusting the connection between the adjusting cylinder of the adjusting seat 4 and the side pressure positioning block 3, the cylinder drives the side pressure positioning block 3 to rotate under the cooperation of the movable shaft. This allows the block to be positioned against the pump body according to the volute structure, thereby stabilizing the side of the pump body and preventing rotation.

[0023] Working principle: In the pump body fixture;

[0024] When machining a volute pump, the pump body is placed on the top surface of the tensioning and centering fixture 11 and pre-tensioned using the structure of the tensioning and centering fixture 11 to position the pump body 2. Then, the first cylinder 5 is activated to drive the first clamping block 6 to press against the surface of the pump body 2 for primary positioning. The second cylinder 8 and the third cylinder 9 are activated to drive the second clamping block 7 and the third clamping block 10 for secondary positioning of the volute pump body. This three-point positioning structure improves the stability of pump body machining. The position of the side pressure positioning block 3 is adjusted by the adjusting seat 4 to ensure that the side pressure positioning block 3 fits against the side of the pump body and limits its movement, preventing the housing from rotating. This allows the pump body to be machined stably with the cooperation of multiple positioning structures, improving the forming accuracy of the pump body.
