When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolt connection, or gluing connection. In short, for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Example 1

[0022] like Figure 1-2As shown, a motor accessory drilling device includes an upper pressing piece 1 and a lower supporting piece 2. The upper pressing piece 1 includes an upper pressing seat 3. A driving mechanism is provided above the upper pressing seat 3. The driving mechanism is composed of a lifting cylinder and a lifting rod fixed on the corresponding equipment, which drives the upper pressing seat 3 to move downward through the lifting cylinder and the lifting rod.

[0023] A mounting seat 4 is provided in the middle of the upper press seat 3. A lower pressing groove 5 with a trapezoidal cross section is provided below the upper press seat 3. A drilling channel 6 is provided between the mounting seat 4 and the lower pressing groove 5. A drill rod 7 is provided on the mounting seat 4. A drill bit 8 is provided at the bottom of the drill rod 7. The drill rod 7 is composed of corresponding axial drive mechanisms and rotation drive mechanisms. In this embodiment, the drill rod 7 is composed of a hydraulic rod and a rotary motor. The hydraulic rod drives the rotary motor and the drill bit 8 axially forward, and the rotary motor drives the drill bit 8 to rotate and drill. Square reinforcing ribs 24 are provided around the outer side of the upper press seat 3. The addition of the reinforcing ribs enables the upper press seat 3 to maintain its shape and position more stably when subjected to external force, reduces unnecessary vibration and displacement, and thus improves the accuracy and stability of drilling.

[0024] The lower bearing member 2 includes a base plate 9, on which a first bearing platform 10 and a second bearing platform 11 and a guide device that are symmetrical to each other are provided. The first bearing platform 10 and the second bearing platform 11 are slidably arranged on the base plate 9 through the guide device. A pad 12 is provided on the top of the first bearing platform 10 and the second bearing platform 11. The opposite sides of the first bearing platform 10 and the second bearing platform 11 are respectively provided with a first groove 13 and a second groove 14. After the first bearing platform 10 and the second bearing platform 11 are docked, a trapezoidal structure that matches the lower pressure groove 5 is formed.

[0025] When drilling, first move the first bearing platform 10 and the second bearing platform 11 toward the middle so that the two are combined together, and then place the motor configuration to be processed in the middle above the first bearing platform 10 and the second bearing platform 11. The lifting cylinder drives the upper press seat 3 to move downward until the upper press seat 3 is pressed above the first bearing platform 10 and the second bearing platform 11, and the upper press groove fits the two sides of the first bearing platform 10 and the second bearing platform 11. The combined structure of the lower press groove 5 and the first bearing platform 10 and the second bearing platform 11 is a trapezoidal structure, preferably an isosceles trapezoidal structure. The inclined surface design of the trapezoidal structure helps to guide the upper press seat 3 to press down smoothly, reduce friction and resistance, and thus facilitate the lower press groove 5 to press the first bearing platform 10 and the second bearing platform 11. Afterwards, the upper top surface of the lower pressing groove 5 is pressed and fixed on the motor parts to be processed, and the drill bit 8 performs a drilling operation on the motor parts to be processed. The waste chips generated by drilling enter the space between the first groove 13 and the second groove 14 to prevent the waste chips from flying around. Then, the upper pressing seat 3 is moved up, the first bearing platform 10 and the second bearing platform 11 are separated, and the waste chips at the bottom of the space between the first groove 13 and the second groove 14 are cleaned. The close cooperation of the trapezoidal structure formed by the upper pressing seat 3 and the first bearing platform 10 and the second bearing platform 11 achieves efficient and stable fixation of the motor parts. This design ensures the stability of the parts during the drilling process, reduces drilling errors caused by shaking or displacement, and improves the accuracy and efficiency of drilling. The setting of the first groove 13 and the second groove 14 effectively collects the waste chips generated during the drilling process, avoids the splashing and scattering of waste chips, and keeps the working environment clean. This not only reduces the workload of cleaning work, but also reduces the safety hazards caused by waste chips. The first carrying platform 10 and the second carrying platform 11 can be easily separated and combined, so as to facilitate cleaning of waste chips in the first groove 13 and the second groove 14 .

[0026] The guide device includes a first guide rod 15, a first fixing plate 16, a second guide rod 17, and a second fixing plate 18. The first fixing plate 16 and the second fixing plate 18 are respectively fixed to the two sides above the bottom plate 9. A first limiting handle 19 is provided at the end of the first guide rod 15. The other end of the first guide rod 15 passes through the first fixing plate 16 and is connected to the first bearing platform 10. A second limiting handle 20 is provided at the end of the second guide rod 17. The other two ends of the second guide rod 17 pass through the second fixing plate 18 and are connected to the second bearing platform 11. A first return spring 25 is provided between the first limiting handle 19 and the first fixing plate 16, and a second return spring 26 is provided between the second limiting handle 20 and the second fixing plate 18. The guide rods can guide the corresponding bearing platforms. Preferably, two first fixing plates 16 and two second fixing plates 18 are provided to further enhance the guiding effect.

[0027] A collection space 21 is provided below the mounting base 4, and the collection space 21 is connected to the drilling channel 6. A negative pressure collection hose 22 is connected to the side of the mounting base 4. One end of the negative pressure collection hose 22 is connected to the collection space 21, and the other end of the negative pressure collection hose 22 is connected to a negative pressure collection pump 23. The negative pressure generated by the negative pressure collection pump 23 can collect and clean the waste chips in the drilling channel 6. The waste chips pass through the drilling channel 6, the collection space 21, and the negative pressure collection hose 22 and enter the negative pressure collection pump 23. The negative pressure collection pump 23 is provided with a corresponding collection bin for collection. The negative pressure generated by the negative pressure collection pump 23 can effectively suck the waste chips generated during the drilling process from the drilling channel 6 and transport them to the collection bin through the collection space 21 and the negative pressure collection hose 22, which helps to keep the working environment clean and tidy, reduce the potential harm of waste chips to equipment and operators, and further improve the cleaning effect.
