Description

Technical Field

[0001] This utility model belongs to the field of drilling and tapping technology, and relates to a drilling and tapping device for a pump cover. Background Technology

[0002] The position and function of the pump cover in pump equipment are crucial. It belongs to the pump casing and is usually installed at one end of the pump body, serving a sealing and supporting function. When producing the pump cover, a hole needs to be drilled in the middle first, and then the hole is threaded internally.

[0003] When machining the pump cover, the component can be placed on the workbench and fixed. Then, the drill bit can be moved to a suitable position to drill holes in the pump cover component. Threads can then be formed inside by cutting and tapping.

[0004] When machining pump cover components, since most of them are circular in shape, it is difficult to fix the pump cover components during drilling and tapping. As a result, the internal threads are easily damaged during the drilling and tapping process. Utility Model Content

[0005] The technical problem to be solved by this utility model is that when processing pump cover components, since most of them are circular, it is difficult to fix the pump cover components during drilling and tapping, which can easily cause damage to the internal threads during the drilling and tapping process.

[0006] The present invention discloses a pump cover drilling and tapping device, comprising a telescopic plate, a top cover fixedly connected to the end of the telescopic plate, a turntable rotatably connected to the middle of the top cover, a plurality of drill bits fixedly connected to the middle of the turntable, a circular cavity fixedly connected to the end of the telescopic plate, a circular ring fixedly connected to the end of the circular cavity, a plurality of second connecting rods fixedly connected to the middle of the inner side of the circular cavity, an auxiliary component provided at the end of the second connecting rods, and a clamping component provided in the middle of the circular ring.

[0007] The clamping assembly includes a torsion spring, a retaining rod, a sliding groove, a first connecting rod, a servo motor, a gear, a rack, and a pressing plate. Multiple sets of torsion springs are fixedly connected to the center of the ring, and each set of torsion springs is hinged to a retaining rod. A sliding groove is formed in the center of the retaining rod, and a first connecting rod is slidably connected to the center of the sliding groove. A servo motor is fixedly connected to the center of the first connecting rod, and a gear is fixedly connected to the output end of the servo motor. A rack is fixedly connected to the center of the retaining rod, and the gear and rack mesh with each other. A pressing plate is fixedly connected to the end of the retaining rod, and an anti-slip component is provided in the center of the pressing plate.

[0008] The anti-slip component includes a straight groove, a first spring, a support rod, a hinge, and a rubber plate. The extrusion plate has a straight groove in the middle, and the first spring is fixedly connected to the middle of the straight groove. The support rod is fixedly connected to the end of the extrusion plate, and the hinge is fixedly connected to the end of the support rod. The rubber plate is hinged to the middle of the hinge, and the rubber plate is fixedly connected to the end of the first spring.

[0009] The auxiliary component includes a circular plate and anti-slip pads. The ends of multiple sets of second connecting rods are fixedly connected to the circular plate, and multiple sets of anti-slip pads are fixedly connected to the middle of the circular plate.

[0010] A filter plate is slidably connected to the center of the circular cavity, and a protective ring is fixed to the bottom of the inner side of the circular cavity. A vibration component is installed inside the protective ring.

[0012] Multiple sets of second springs are fixedly connected to the center of the circular cavity, and the ends of the second springs are fixedly connected to the filter plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the pump cover to be processed can be positioned by the auxiliary components, and then it can be fixed by the clamping components. This reduces the shaking of the pump cover components when processing it with a drill bit, thereby reducing the occurrence of damage during the processing of the pump cover.

[0014] By moving the first connecting rod in the middle of the chute, the tilt angle of the retaining rod can be controlled, thereby allowing the pressing plate at the end of the retaining rod to clamp and fix the pump cover element, thus reducing the shaking during processing and reducing the possibility of damage to the pump cover element during processing.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Example 1

[0024] like Figures 1-3 As shown, it includes a telescopic plate 1, with a top cover 2 fixedly connected to the end of the telescopic plate 1. The telescopic action of the telescopic plate 1 can drive the top cover 2 to move up and down. A turntable 3 is rotatably connected to the middle of the top cover 2. The turntable 3 can be flipped in the middle of the top cover 2. Multiple sets of drill bits 4 are fixedly connected to the middle of the turntable 3. A circular cavity 5 is fixedly connected to the end of the telescopic plate 1. A circular ring 6 is fixedly connected to the end of the circular cavity 5. Multiple sets of second connecting rods 26 are fixedly connected to the middle of the inner side of the circular cavity 5. An auxiliary component is provided at the end of the second connecting rod 26, which can place the pump cover to be processed on the auxiliary component. A clamping component is provided in the middle of the circular ring 6, which can clamp the pump cover on the auxiliary component.

[0025] The pump cover to be processed can be positioned by the auxiliary components, and then it can be fixed by the clamping components. This reduces the shaking of the pump cover components when processing it with drill bit 4, thereby reducing the possibility of damage during the processing of the pump cover.

[0026] The clamping assembly includes a torsion spring 7, a retaining rod 8, a slide groove 9, a first connecting rod 10, a servo motor 11, a gear 12, a rack 13, and a pressing plate 14. Multiple sets of torsion springs 7 are fixedly connected to the center of the ring 6, and each set of torsion springs 7 has a retaining rod 8 hinged to its center. The retaining rod 8 can rotate under the action of the torsion springs 7. A slide groove 9 is formed in the center of the retaining rod 8, and the first connecting rod 10 is slidably connected to the center of the slide groove 9, allowing the first connecting rod 10 to slide within the center of the slide groove 9. A servo motor 11 is fixedly connected to the center of the first connecting rod 10. The servo motor 11 has a gear 12 fixedly connected to its output end, and a rack 13 fixedly connected to the middle of the stationary rod 8. The gear 12 and the rack 13 mesh with each other. The servo motor 11 drives the gear 12 to rotate. Then, through the meshing action between the gear 12 and the rack 13, the first connecting rod 10 can be driven to slide in the middle of the slide groove 9. The end of the stationary rod 8 is fixedly connected to a pressing plate 14, which can press the pump cover placed on the auxiliary component. The pressing plate 14 is provided with an anti-slip component in the middle.

[0027] The tilt angle of the retaining rod 8 can be controlled by the movement of the first connecting rod 10 in the middle of the slide groove 9, thereby allowing the pressing plate 14 at the end of the retaining rod 8 to clamp and fix the pump cover element, thus reducing the shaking during processing and reducing the damage to the pump cover element during processing.

[0028] The anti-slip assembly includes a straight groove 15, a first spring 16, a support rod 17, a hinge 18, and a rubber plate 19. The extrusion plate 14 has a straight groove 15 in the middle, and the first spring 16 is fixedly connected to the middle of the straight groove 15. The support rod 17 is fixedly connected to the end of the extrusion plate 14, and the hinge 18 is fixedly connected to the end of the support rod 17. The rubber plate 19 is hinged to the middle of the hinge 18, and the rubber plate 19 is fixedly connected to the end of the first spring 16.

[0029] After placing the pump cover to be processed in the middle of the auxiliary assembly, the rubber plate 19 can first contact its side. Then the rubber plate 19 can rotate in the middle of the hinge 18, thereby compressing the first spring 16 inside the straight groove 15. This process can improve the fixing effect when the pump cover needs to be fixed and reduce the shaking during processing.

[0030] The auxiliary components include a circular plate 27 and an anti-slip pad 28. Multiple sets of second connecting rods 26 are fixed to the ends of the circular plate 27, and multiple sets of anti-slip pads 28 are fixed to the middle of the circular plate 27.

[0031] When the pump cover is placed in the middle of the circular plate 27, the friction between the circular plate 27 and the pump cover can be increased by the anti-slip pad 28, which can reduce the shaking of the pump cover during the processing.

[0032] Example 2

[0033] like Figures 1-4As shown, a filter plate 25 is slidably connected in the middle of the circular cavity 5, which can filter the debris generated during processing. A protective ring 29 is fixed to the bottom of the inner side of the circular cavity 5. A vibration component is installed inside the protective ring 29 to make the filter plate 25 vibrate.

[0034] When machining the pump cover, filter plate 25 can be used to collect the debris generated after machining, and then the separation between the debris in the middle of filter plate 25 and the coolant can be accelerated by the vibration assembly.

[0035] The vibration assembly includes an arc-shaped support plate 20, a motor 21, a rotating shaft 22, and a push plate 23. The arc-shaped support plate 20 is fixedly connected to the middle of the circular cavity 5, the motor 21 is fixedly connected to the middle of the arc-shaped support plate 20, the rotating shaft 22 is fixedly connected to the output end of the motor 21, and the push plate 23 is fixedly connected to the middle of the rotating shaft 22.

[0036] The operation of the motor 21 can drive the rotating shaft 22 to rotate, and then the push plate 23 can knock the bottom of the filter plate 25 at intervals, thereby causing the filter plate 25 to vibrate, which can improve the separation speed between debris and coolant.

[0037] Multiple sets of second springs 24 are fixedly connected to the middle of the circular cavity 5, and the ends of the second springs 24 are fixedly connected to the filter plate 25.

[0038] When the filter plate 25 vibrates, the second spring 24 can be used to pull the filter plate 25, thereby increasing the rate at which the filter plate 25 returns to its original position and thus improving the vibration efficiency of the filter plate 25.

[0039] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
