[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of this utility model can be combined with each other.

[0026] The following description sets forth many specific details to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments described in the specification are only some embodiments of the present invention, and not all embodiments.

[0027] Combination Figures 1 to 6As shown, the self-priming pump housing drilling and tapping clamping device provided in this embodiment of the present invention includes a housing 6 to be processed, a baffle 5 which is attached to one side of the housing 6 to be processed, and a clamping block 7 which is lifted and installed on the other side of the housing 6 to be processed. The clamping block 7 is equipped with clamping parts on the side of the housing 6 to be processed and its bottom surface. The outer wall of the housing 6 to be processed is provided with a threaded hole processing position b and a through hole processing position c. When processing the threaded hole processing position b, the clamping part on the side wall abuts against the side of the housing 6 to be processed away from the baffle 5. When processing the through hole processing position c, the lower clamping part abuts against the top surface of the housing 6 to be processed.

[0028] Among them, the wire hole processing position b is the first processing point 61 and the second processing point 62, the through hole processing position c is the third processing point 63, the worktable 1, the clamping block 7 is installed on the worktable 1, two hydraulic support legs 8 are fixedly connected to the worktable 1, the two sides of the clamping block 7 are fixedly connected to the connecting block 72 on the same side, the upper ends of the two hydraulic support legs 8 are respectively fixedly connected to the connecting block 72 on the same side, the worktable 1 has a first slot 11 along the length direction, the movable plate 2 is slidably connected in the first slot 11, the movable plate 2 is fixedly connected to the flexible support 3, and the shell to be processed 6 is placed on the flexible support 3.

[0029] A first rubber pad 51 is fixedly connected to the baffle 5. The first rubber pad 51 fits against the shell 6 to be processed. The rubber pad can protect the support point and prevent excessive extrusion pressure from damaging the support point or the shell. During drilling, the rubber pad can absorb some vibration and impact, making the drilling process more stable.

[0030] Among them, the flexible support 3 is a spring rod with the support end facing upward and a concentrated and evenly distributed structure that can control its rebound.

[0031] Therefore, by setting the shell to be processed on a sliding flexible support, and then using a lifting clamping block and baffle to clamp the other surfaces of the shell not to be drilled, the clamping position can be adjusted by sliding the flexible support and lifting clamping block. There is no need to remove the shell to be processed and re-clamp it. Drilling of three processing points can be completed in one process, which improves work efficiency and work quality.

[0032] In some embodiments, such as Figure 1 and Figure 6 As shown, a cylinder 4 is fixedly connected to the flexible support 3, and a support block 41 is fixedly connected to the output end of the cylinder 4. The support block 41 is in contact with the third processing point 63.

[0033] The support block 41 is provided with a dust collection groove 411, which can collect the dust generated by drilling and prevent the dust from flying and affecting the working environment.

[0034] Therefore, after the drilling at the first processing point 61 is completed, the cylinder 4 is activated, driving the support block 41 to fit against the third processing point 63. The dust collection groove 411 on the drive support block 41 collects the generated dust, while preventing the support block 41 from being damaged by the drilling through the shell 6 to be processed.

[0035] In some embodiments, such as Figure 1 and Figure 5 As shown, it also includes a drive mechanism 9, which includes a transmission part and an execution part. The execution part includes a second slot 94, which is opened at one end of the worktable 1. A screw 92 is rotatably connected in the second slot 94. The screw 92 passes through the second slot 94 and is rotatably connected to the first slot 11. The movable plate 2 is threadedly connected to the screw 92. The transmission part includes a motor 90, which is fixedly connected to the worktable 1. The output end of the motor 90 extends through the worktable 1 into the second slot 94. The output end located in the second slot 94 is fixedly connected to a driving bevel gear 91. A driven bevel gear 93 is fixedly connected to the screw 92. The driving bevel gear 91 and the driven bevel gear 93 mesh.

[0036] Therefore, the motor 90 is turned on, which drives the active bevel gear 91 to rotate, which in turn causes the driven bevel gear 93 to rotate, causing the screw 92 to rotate, and the movable plate 2 to slide in the first slot 11.

[0037] The following is in conjunction with the appendix Figure 1-5 A specific embodiment of this utility model is described below:

[0038] like Figures 1-6 As shown, the device includes a housing 6 to be processed, a baffle 5 attached to one side of the housing 6 to be processed, and a clamping block 7, which is lifted and installed on the other side of the housing 6 to be processed. The clamping block 7 is equipped with clamping components on the side of the housing 6 to be processed and its bottom surface. The outer wall of the housing 6 to be processed has a wire hole processing position b and a through hole processing position c. When processing the wire hole processing position b, the clamping component on the side wall abuts against the side of the housing 6 to be processed away from the baffle 5. When processing the through hole processing position c, the lower clamping component abuts against the top surface of the housing 6 to be processed.

[0039] In actual use, the shell 6 to be processed is placed on the flexible support 3, with one side of the shell 6 in contact with the first rubber pad 51 on the baffle 5. The motor 90 is turned on, driving the active bevel gear 91 to rotate, which in turn causes the driven bevel gear 93 to rotate, causing the screw 92 to rotate, making the movable plate 2 slide in the first slot 11. At this time, the hydraulic support leg 8 is lowered, causing the clamping block 7 to descend. When the side of the shell 6 where the second processing point is located is in contact with the second rubber pad 71, the sliding of the movable plate 2 is stopped. At this time, the shell 6 is stably clamped from multiple directions by the cooperation of the second rubber pad 71, the baffle 5, and the flexible support 3, and the first processing point 61 and the third processing point 63 are exposed. At this time, the first processing point 61 can be drilled. After the first processing point 61 is drilled, the cylinder 4 is turned on to drive the support. The support block 41 is engaged with the third processing point 63, driving the dust collection groove 411 on the support block 41 to collect the generated dust, while preventing damage to the support block 41 during drilling through the shell 6 to be processed. After drilling at the third processing point 63, the clamping block 7 is raised, and the movable plate 2 continues to slide. When the clamping rod 73 is aligned with the top of the shell 6 to be processed, the movable plate 2 stops sliding, and the clamping block 7 is lowered so that the clamping rod 73 clamps the upper surface of the shell 6 to be processed. At this time, the shell 6 to be processed is clamped stably in multiple directions, and the second processing point 62 is exposed. At this time, drilling can be performed on the second processing point 62. After completion, the shell 6 to be processed is removed from the device to complete the drilling of the three processing points. The shell to be processed can be clamped stably in multiple directions with only one fixation without affecting the surface to be processed, thus improving work efficiency and work quality.
