The outer wall of the left front clamping rod 25 is threaded, and the left front clamping rod 25 is threadedly connected to the left front clamping plate 23, thus facilitating adjustment of the distance between the left front clamping rod 25 and the bearing body. Correspondingly, the right front clamping plate 27 has threaded holes spaced from top to bottom, and one or two right front clamping rods 29 can be provided. The right front clamping rod 29 is threadedly connected to the right front clamping plate 27, thus facilitating adjustment of the distance between the right front clamping rod 29 and the bearing body. Distance; Locking components are used multiple times in this utility model. The front left support seat 8, front right support seat 9, rear left support seat 11, rear right support seat 12, left clamping seat 21, right clamping seat 22, pressing connecting seat 16, and front pressing seat 45 are slidably connected to the mounting base 1. The front left support seat 8, front right support seat 9, rear left support seat 11, rear right support seat 12, left clamping seat 21, right clamping seat 22, pressing connecting seat 16, and front pressing seat 45 are fixedly connected to the mounting base 1 via locking components. The locking components on these components are structurally related to the locking components. Similarly, the locking component includes a locking bolt. The slider has a threaded hole, and the lower end of the locking bolt is threadedly connected to the slider. The locking bolt moves the slider up and down. When the slider is placed downwards within the slide rail, it can slide. When the slider is pushed upwards against the slide rail, the upper end of the slider presses against the upper end of the slide rail, preventing the slider from moving relative to the slide rail. The slide rail is inverted T-shaped, and the slider is designed to cooperate with it. Taking the locking component between the front left support 8 and the mounting base 1 as an example, in this utility model, the mounting base 1 has slide rails 5 spaced from front to back. The front left support 8 has bolt holes on both its front and rear sides. The locking bolt passes through the bolt holes and enters the slide rail 5, threadedly connecting to the slider. The locking bolt is threadedly connected to the front left support 8, and the locking bolt corresponds one-to-one with the slider. When... When the front left support seat 8 needs to move left or right, loosen the locking bolt. The locking bolt moves the slider downwards, placing the slider inside the slide rail. At this time, the front left support seat 8 is slidably connected to the mounting base 1 via the slider. When it is necessary to lock the position of the front left support seat 8, tighten the locking bolt. The locking bolt moves the slider upwards, causing the upper end of the slider to abut against the inner wall of the upper end of the slide rail, thus preventing movement and fixing the position of the front left support seat 8. The sliding and locking structures between the front right support seat 9, rear left support seat 11, rear right support seat 12, left clamping seat 21, right clamping seat 22, pressing connection seat 16, front compression seat 45, and the mounting base 1 are the same as those between the front left support seat 8 and the mounting base 1, and will not be described in detail. (See attached diagram) Figure 3 This is a schematic diagram of the split-case pump bearing body to be clamped in this embodiment. Figure 3(a) is a schematic diagram of the front end face of the bearing body, with attached... Figure 3 (b) is a schematic diagram of the rear end face of the bearing body. For ease of description, please refer to the attached diagram. Figure 1To illustrate the orientation, when clamping the pump bearing body, adjust the distance between the front left support seat 8 and the front right support seat 9, and the distance between the rear left support seat 11 and the rear right support seat 12, according to the position of the front and rear lower end faces of the bearing body. The front left support seat 8 and the front right support seat 9 are arranged opposite each other to form a V-shaped front clamping surface, and the rear left support seat 11 and the rear right support seat 12 are arranged opposite each other to form a V-shaped rear clamping surface. After the position is appropriate, lock the locking pieces on the front left support seat 8, the front right support seat 9, the rear left support seat 11, and the rear right support seat 12. Place the bearing body on the front left support seat 8, the front right support seat 9, the rear left support seat 11, and the rear right support seat 12, and press the clamping frame 18 onto the front upper end face of the bearing body. The structure of the lower end face of the clamping frame 18 matches the structure of the front upper end face of the bearing body. The two clamping screws 17 are fixedly connected to the clamping connecting seat 16 through the clamping holes 20. Adjust the locking elements on the left clamping seat 21 and the right clamping seat 22 so that they move closer to the bearing body. The left front clamping rod 25 and the right front clamping rod 29 abut against both sides of the front end face of the bearing body, and the left rear bolt 26 and the right rear bolt 30 abut against both sides of the rear end face of the bearing body. Fix the clamping screws 17, rotate the clamping nut 19 (a washer can be placed at the lower end of the clamping nut 19), and lock the locking elements on the left clamping seat 21 and the right clamping seat 22. Rotate the left rear bolt 26 and the right rear bolt 30 so that the left and right front ends of the bearing body abut against the left front clamping rod 25 and the right front clamping rod 29, and the left and right rear ends of the bearing body abut against the left rear bolt 26 and the right rear bolt 30. With the 30 plates abutting against each other, the clamping nut 19 moves downwards, abutting against the clamping frame 18 and pressing it downwards to fix the clamping frame 18 to the bearing body. Then, rotate the left support screw 32 and the right support screw 36 to adjust the height of the left clamping plate 34 and the right clamping plate 38 so that the lower right end of the left clamping plate 34 abuts against the left side protruding platform of the bearing body, and the lower left end of the right clamping plate 38 abuts against the right side protruding platform of the bearing body. After the positions are appropriate, fix the left adjusting screw 33 and the right adjusting screw 37, and rotate the left lower clamping nut 35 and the right lower clamping nut 39 respectively, so that the left lower clamping nut 35 and the right lower clamping nut 39 move downwards. The lower end of the left lower clamping nut 35 abuts against and is fixed to the left clamping plate 34, and the lower end of the right lower clamping nut 39 abuts against the right lower clamping nut 38. 39 are abutted and fixed together. Then, rotate the left extrusion rod 41 and the right extrusion rod 42 so that the left extrusion rod 41 abuts against the left side of the bearing body and the right extrusion rod 42 abuts against the right side of the bearing body. Rotate the left extrusion rod 41 and the right extrusion rod 42 so that the left extrusion rod 41 abuts against the left side of the rear left support seat 11 and the right extrusion rod 42 abuts against the right end face of the rear right support seat 12. Finally, adjust the front extrusion seat 45 so that the front extrusion seat 45 is located in the middle of the front part of the lower end of the bearing body. Lock the locking part on the front extrusion seat 45. Then rotate the front extrusion screw 46 so that the front extrusion screw 46 abuts against the bearing body, thus completing the clamping of the split-case pump bearing body. After clamping, fix the mounting base on the rotatable worktable of the machine tool. The mounting base is provided with threaded holes and can be detachably connected to the machine tool worktable by screws.This invention allows for the machining of the front and rear faces of the split-case pump bearing housing. The machine tool machining process utilizes existing technology and will not be detailed here. After machining, the mounting base is removed, and the bearing housing is removed by reversing the steps described above. The next bearing housing to be machined can then be clamped. This invention features a simple structure, allows for quick clamping changes, high work efficiency, and stable clamping.

[0041] This utility model, due to the above-mentioned structure, has the advantages of simple structure, convenient clamping, and fast and stable operation.
