Description

Technical Field

[0001] The utility model belongs to the technical field of motor processing equipment and relates to a drilling and clamping device, in particular to a drilling and clamping device for a motor pressure plate. Background Art

[0002] A motor pressure plate is a metal plate used to apply pressure, secure, or adjust the position of components within a motor (especially generators and large electric motors). It is typically designed to ensure proper alignment and tight fit between the motor's internal components, maintaining stable operation and efficient performance. Drilling holes in the motor pressure plate is a precise and critical manufacturing step, requiring strict adherence to design drawings, the use of appropriate tools and equipment, precise marking and positioning, and meticulous drilling on a stable drilling machine to ensure that the hole diameter, position, and wall quality meet high standards to safeguard the overall performance and stability of the motor pressure plate.

[0003] The clamping equipment for motor platen drilling is specially designed to ensure drilling accuracy and stability. It firmly clamps the motor platen on the equipment through precise positioning and clamping mechanisms to support efficient and accurate drilling operations.

[0004] Existing drilling and clamping equipment for motor pressure plates has problems such as low adaptability, low continuous positioning accuracy and low drilling efficiency.

[0005] Based on this, we propose a drilling and clamping device for motor pressure plates, which is suitable for different models of motor pressure plates and has high positioning accuracy and drilling processing efficiency. Utility Model Content

[0006] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a drilling and clamping device for a motor pressure plate. The technical problem to be solved by this utility model is: how to realize the accurate clamping and positioning and rapid drilling of motor pressure plates of different models by the drilling and clamping device.

[0007] The purpose of this utility model can be achieved through the following technical solutions:

[0008] A drilling and clamping device for a motor pressure plate includes a stand mechanism, which is provided with a horizontal conveying mechanism and two vertical sliding mechanisms. The horizontal conveying mechanism is in the middle of the two vertical sliding mechanisms, and the two vertical sliding mechanisms are arranged opposite to each other on the left. The vertical sliding mechanism on the left is provided with a clamping mechanism, and the clamping mechanism is located directly above the horizontal conveying mechanism. The clamping mechanism is provided with a limiting mechanism, and the vertical sliding mechanism on the right is provided with a drilling and grinding mechanism, and the stand mechanism is provided with a chip blowing mechanism.

[0009] The working principle of this utility model is:

[0010] Preparation: Select a positioning block that matches the shape of the motor pressure plate, cooperate with the corresponding screw through the two adjustment blocks on the right vertical sliding mechanism, and adjust the horizontal distance between the support and the motor pressure plate according to the distance from the motor pressure plate drilling hole to the center of the motor pressure plate, thereby adjusting the drilling and grinding positions. The angle scale cooperates with the pointer to achieve the sliding manual screw rod to the corresponding angle. The angle is related to the number of holes drilled in the motor pressure plate. Adjust the sliding manual screw rod according to the distance from the motor pressure plate drilling hole to the center of the motor pressure plate, thereby changing the distance between the positioning push rod and the axis of the arc-shaped sliding hole. Select a suitable tapered rubber block according to the hole radius. Replace the appropriate drill bit and grinding head according to the process requirements of drilling and grinding the motor pressure plate.

[0011] Turn on the air compressor and the air valve. The air compressor is responsible for providing wind power to the electric air valve. The electric air valve sends strong wind power to the drilling site through the blowing hose, blowing the drill chips generated by the drilling into the chip collection box, and placing the motor pressure plate on the rotating placement table on the moving slider. The horizontal electric screw member transports the motor pressure plate on the rotating placement table to the bottom of the electric clamping claw. For thin motor pressure plates or those without through holes inside, the inner side of the clamping claw can be used to clamp them. For motor pressure plates with through holes inside, the four clamping claws can be closed and pressed into the through holes to tighten the motor pressure plate, effectively limiting the motor pressure plate. The vertical electric screw member on the left drives the sliding block to slide downward, and tightens the motor pressure plate through the conical rubber block, so that the drilling and grinding mechanism is Drilling and grinding the first hole are smoother and the positioning is more accurate. The right vertical electric screw member drives the sliding block to slide downward, and the drilling drive motor drives the drill bit to drill the motor pressure plate. After the drilling is completed, the right vertical electric screw member drives the sliding block to slide upward, thereby driving the drill bit to reset. The second cam divider drives the rotating plate to rotate intermittently, thereby driving the drilling drive motor and the grinding drive motor to rotate intermittently, so that the grinding drive motor is directly above the drill hole. The right vertical electric screw member drives the sliding block to slide downward, and the grinding drive motor drives the grinding head to grind the drilled hole. After the grinding is completed, the vertical electric screw member drives the sliding block to slide upward, thereby driving the grinding head to reset. This is the drilling and grinding action.

[0012] The cam divider drives the through-hole connector to rotate a corresponding angle, thereby driving the electric clamp to rotate a corresponding angle (the quotient of 360° divided by the number of holes), thereby driving the motor pressure plate to rotate synchronously with the rotating placement table, so that the first hole of the motor pressure plate is opposite to the positioning push rod, the positioning push rod descends, extends into the hole through the tapered rubber block and presses against the side of the hole, thereby effectively limiting the motor pressure plate, and repeating the drilling and grinding actions on the motor pressure plate;

[0013] After all holes are drilled, the drilling and grinding mechanism, the limit mechanism and the clamping mechanism are reset, the air valve is closed, the horizontal electric screw member drives the rotating placement table to reset, and the motor pressure plate with the holes drilled is removed.

[0014] The platform mechanism includes an operating table, a chip collection box is fixed to the rear side of the operating table, the front side opening of the chip collection box is directly opposite to the horizontal conveying mechanism, and an air outlet is provided on the rear side of the chip collection box;

[0015] The horizontal conveying mechanism includes a horizontal electric screw member, which is fixed on the operating table. The tail of the horizontal electric screw member is facing the chip collection box. A movable slider is provided on the horizontal electric screw member for transmission. A detachable rotating placement table is rotatably provided on the movable slider, and a detachable positioning block is embedded in the rotating placement table.

[0016] With the above structure, the chip blowing mechanism is directed toward the drilling and grinding areas and the chip collecting box. The chip blowing mechanism blows the drill cuttings generated by drilling and grinding into the chip collecting box, which is used to recycle the drill cuttings.

[0017] Select a positioning block that matches the shape of the motor pressure plate. The positioning block is used to perform preliminary positioning of the motor pressure plate. Place the motor pressure plate on the rotating placement table on the movable slider. The rotating placement table can rotate to any angle with the motor pressure plate. The positioning block is used to position the motor pressure plate. The horizontal electric screw member transports the motor pressure plate on the rotating placement table to the corresponding position.

[0018] The chip blowing mechanism includes an air compressor and two electric air valves. The two electric air valves are fixed on the operating table. The air compressor is arranged inside the operating table. The air inlets of the two electric air valves are connected to the air outlets of the air compressor. The air outlets of the two electric air valves are provided with shapeable blowing hoses, and the directions of the two blowing hoses are facing the drilling holes and the front opening of the chip collection box.

[0019] With the above structure, the air compressor is responsible for providing wind power to the electric air valve. The electric air valve sends strong wind power to the drilling site through the blowing hose, blowing the drill cuttings generated by the drilling into the chip collection box, making the positioning of the limit mechanism more accurate and realizing the recovery of drill cuttings at the same time.

[0020] The vertical sliding mechanism includes two adjustment blocks, which are symmetrically fixed on the operating table. Support members are provided on the two adjustment blocks and the operating table for sliding. Screws are threaded on the two adjustment blocks, and the lower ends of the screws are in contact with the support members. A vertical electric screw member is provided on the support member, and a sliding block is provided on the vertical electric screw member for transmission.

[0021] The above structure is adopted, and the two adjustment blocks on the left vertical sliding mechanism cooperate with the screws on the two adjustment blocks to adjust the position of the support during installation. The two adjustment blocks on the right vertical sliding mechanism cooperate with the corresponding screws to adjust the horizontal distance between the support and the motor pressure plate according to the distance requirement from the motor pressure plate drilling hole to the center of the motor pressure plate. The vertical electric screw drives the sliding block to slide up and down.

[0022] The clamping mechanism includes a cam divider, which is fixed to the lower end of the sliding block on the left vertical sliding mechanism. A through-hole connector is fixed to the lower end of the cam divider, and the output shaft of the cam divider passes through the through-hole connector. The output shaft of the cam divider is fixed to an electric clamping member. The four clamping jaws of the electric clamping member have anti-slip rubber pads on the inner sides. When the four clamping jaws are closed, a cone with a larger top and a smaller bottom is formed on the outer side.

[0023] With the above structure, the cam divider drives the through-hole connector to rotate a corresponding angle, thereby driving the electric clamping member to rotate a corresponding angle (the quotient of 360° divided by the number of holes). For thin motor pressure plates or those without through-holes inside, the inner side of the clamping jaws can be used for clamping. The anti-slip rubber pads on the inner sides of the four clamping jaws make the clamping more stable. For motor pressure plates with through-holes inside, the four clamping jaws can be closed and pressed into the through-holes to tighten the motor pressure plate, effectively limiting the motor pressure plate. The electric clamping jaws cooperate with the rotating placement table to drive the motor pressure plate to rotate accurately.

[0024] The limiting mechanism includes an angle adjustment plate, which is placed horizontally and fixed on the through-hole connector. An arc-shaped sliding hole is provided on the angle adjustment plate, and an angle scale is marked on the arc-shaped sliding hole. The axis of the arc-shaped sliding hole is collinear with the axis of the through-hole connector. A manual screw rod is provided for sliding inside the arc-shaped sliding hole, and a pointer is provided on the manual screw rod. A vertically arranged positioning push rod is fixed to the lower side of the sliding block of the manual screw rod, and a detachable conical rubber block is provided at the lower end of the positioning push rod, and the conical rubber block is larger at the top and smaller at the bottom.

[0025] With the above structure, the angle scale cooperates with the pointer to realize sliding the manual screw rod to the corresponding angle. The angle is related to the number of holes drilled in the motor pressure plate. The sliding manual screw rod is adjusted according to the distance requirement from the drilled hole of the motor pressure plate to the center of the motor pressure plate, thereby changing the distance between the positioning push rod and the axis of the arc-shaped sliding hole. A conical rubber block of matching size is selected according to the hole radius. The motor pressure plate is tightened by the conical rubber block, so that the drilling and grinding mechanism is smoother and the positioning is more accurate when drilling and grinding the first hole. The conical rubber block extends into the hole and presses against the side of the hole to achieve effective limiting of the motor pressure plate.

[0026] The drilling and grinding mechanism includes a cam divider 2, which is fixed to the lower end of the sliding block on the right vertical sliding mechanism. A rotating plate is fixed on the output shaft of the cam divider 2, and a drilling drive motor and a grinding drive motor symmetrically arranged are fixed to the lower end of the rotating plate. A detachable drill bit is provided at the lower end of the drilling drive motor, and a detachable grinding head is provided at the lower end of the grinding drive motor.

[0027] With the above structure, the cam divider 2 is used to drive the rotating plate to rotate intermittently, thereby driving the drilling drive motor and the grinding drive motor to rotate intermittently. The drilling drive motor is used to drive the drill bit to drill the motor pressure plate, and the grinding drive motor is used to drive the grinding head to grind the drilled hole to remove burrs from the hole edges, so as to facilitate the positioning of the conical rubber block on the hole. Both the drill bit and the grinding head can be replaced according to the process requirements of drilling and grinding of the motor pressure plate.

[0028] Compared with the existing technology, the drilling and clamping equipment for the motor pressure plate has the following advantages:

[0029] 1. The clamping mechanism cooperates with the horizontal conveying mechanism to achieve accurate pressing and positioning of different types of motor pressure plates.

DETAILED DESCRIPTION

[0039] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0040] like Figures 1-4 As shown, the drilling and clamping equipment for the motor pressure plate includes a stand mechanism 1, which is provided with a horizontal conveying mechanism 2 and two vertical sliding mechanisms 3. The horizontal conveying mechanism 2 is in the middle of the two vertical sliding mechanisms 3, and the two vertical sliding mechanisms 3 are arranged opposite to each other. The vertical sliding mechanism 3 on the left is provided with a clamping mechanism 4, and the clamping mechanism 4 is located directly above the horizontal conveying mechanism 2. The clamping mechanism 4 is provided with a limiting mechanism 5, the vertical sliding mechanism 3 on the right is provided with a drilling and grinding mechanism 6, and the stand mechanism 1 is provided with a chip blowing mechanism 7.

[0041] In this embodiment, the motor pressure plate is placed on the horizontal conveying mechanism 2, and the horizontal conveying mechanism 2 conveys the motor pressure plate to the bottom of the clamping mechanism 4. The clamping mechanism 4 has several different clamping methods. The appropriate clamping method is selected according to the shape of the motor pressure plate. The vertical sliding mechanism 3 on the right can slide left and right on the platform mechanism 1. The position of the vertical sliding mechanism 3 on the right is adjusted according to the distance from the drilling hole to the center of the motor pressure plate. The limiting mechanism 5 is operated according to the distance from the drilling hole to the center of the motor pressure plate and the number of drilling holes. At the same time, the limiting mechanism 5 descends to clamp the motor pressure plate, and the drilling and grinding mechanism 6 drills and grinds the first hole of the motor pressure plate.

[0042] After drilling and grinding are completed, the limit mechanism 5 is reset, the drilling and grinding mechanism 6 is reset, and the clamping mechanism 4 drives the motor pressure plate to rotate the corresponding angle (360° divided by the quotient of the number of holes to be drilled) so that the first hole of the motor pressure plate is facing the limit mechanism 5. The limit mechanism 5 descends and extends into the hole, pressing against the motor pressure plate to accurately position the motor pressure plate, and the drilling and grinding mechanism 6 continues drilling and grinding the holes, and the above operation is repeated;

[0043] During drilling and grinding, the chip blowing mechanism 7 continuously blows air to the drill hole of the motor pressure plate, blows the drill chips away from the drill hole, and collects them through the stand mechanism 1 to achieve drill chip recovery.

[0044] The platform mechanism 1 includes an operating table 101, a chip collecting box 102 is fixed to the rear side of the operating table 101, the front side opening of the chip collecting box 102 is directly opposite to the horizontal conveying mechanism 2, and an air outlet is provided on the rear side of the chip collecting box 102;

[0045] The horizontal conveying mechanism 2 includes a horizontal electric screw member 201, which is fixed on the operating table 101. The tail of the horizontal electric screw member 201 is facing the chip collection box 102. A movable slider is provided on the horizontal electric screw member 201 for transmission. A detachable rotating placement table 202 is rotatably provided on the movable slider, and a detachable positioning block 203 is embedded in the rotating placement table 202.

[0046] In this embodiment, the chip blowing mechanism 7 is directed toward the drilling and grinding locations and the chip collecting box 102. The chip blowing mechanism 7 blows the drill cuttings generated by the drilling and grinding into the chip collecting box 102. The chip collecting box 102 is used to recycle the drill cuttings.

[0047] Select a positioning block 203 that matches the shape of the motor pressure plate. The positioning block 203 is used to preliminarily position the motor pressure plate. Place the motor pressure plate on the rotating placement table 202 on the movable slider. The rotating placement table can rotate to any angle in conjunction with the motor pressure plate. The positioning block 203 is used to position the motor pressure plate. The horizontal electric screw member 201 transports the motor pressure plate on the rotating placement table to the corresponding position.

[0048] The chip blowing mechanism 7 includes an air compressor and two electric air valves. The two electric air valves are fixed on the operating table 101. The air compressor is arranged inside the operating table 101. The air inlets of the two electric air valves are connected to the air outlets of the air compressor. The air outlets of the two electric air valves are provided with shapeable blowing hoses, and the directions of the two blowing hoses are facing the drilling holes and the front opening of the chip collection box 102.

[0049] In this embodiment, the air compressor is responsible for providing wind power to the electric air valve, and the electric air valve sends strong wind power to the drilling site through the blowing hose, blowing the drill cuttings generated by the drilling into the chip collection box 102, making the positioning of the limiting mechanism 5 more accurate and realizing the recovery of drill cuttings at the same time.

[0050] The vertical sliding mechanism 3 includes two adjustment blocks 302, which are symmetrically fixed on the operating table 101. A support member 301 is slidingly provided on the two adjustment blocks 302 and the operating table 101. A screw is threaded on the two adjustment blocks 302, and the lower end of the screw abuts against the support member 301. A vertical electric screw member 303 is provided on the support member 301, and a sliding block 304 is transmitted on the vertical electric screw member 303.

[0051] In this embodiment, the two adjustment blocks 302 on the left vertical sliding mechanism 3 cooperate with the two screws on the adjustment blocks 302 to adjust the position of the support member 301 during installation. The two adjustment blocks 302 on the right vertical sliding mechanism 3 cooperate with the corresponding screws to adjust the horizontal distance between the support member 301 and the motor pressure plate according to the distance requirement from the motor pressure plate drilling hole to the center of the motor pressure plate. The vertical electric screw member 303 drives the sliding block 304 to slide up and down.

[0052] The clamping mechanism 4 includes a cam divider 401, which is fixed to the lower end of the sliding block 304 on the left vertical sliding mechanism 3. The lower end of the cam divider 401 is fixed with a through-hole connector 402. The output shaft of the cam divider 401 passes through the through-hole connector 402. The output shaft of the cam divider 401 is fixed with an electric clamping member 403. The four clamping jaws of the electric clamping member 403 have anti-slip rubber pads on the inner side. When the four clamping jaws are closed, the outer side forms a cone with a larger upper part and a smaller lower part.

[0053] In this embodiment, the cam divider 401 drives the through-hole connector 402 to rotate a corresponding angle, thereby driving the electric clamping member 403 to rotate a corresponding angle (the quotient of 360° divided by the number of holes). For thin motor pressure plates or those without through-holes inside, the inner side of the clamping member can be used for clamping. The anti-slip rubber pads on the inner side of the four clamping members make the clamping more stable. For motor pressure plates with through-holes inside, the four clamping members can be closed together and pressed into the through-holes to tighten the motor pressure plate, thereby effectively limiting the motor pressure plate. The electric clamping member 403 cooperates with the rotating placement table 202 to drive the motor pressure plate to rotate accurately.

[0054] The limiting mechanism 5 includes an angle adjustment plate 501, which is placed horizontally and fixed on the through-hole connector 402. An arc-shaped sliding hole is provided on the angle adjustment plate 501, and an angle scale is marked on the arc-shaped sliding hole. The axis of the arc-shaped sliding hole is collinear with the axis of the through-hole connector 402. A manual screw rod 502 is provided for sliding inside the arc-shaped sliding hole, and a pointer is provided on the manual screw rod 502. A vertically arranged positioning push rod 503 is fixed to the lower side of the sliding block of the manual screw rod 502, and a detachable conical rubber block is provided at the lower end of the positioning push rod 503, which is larger at the top and smaller at the bottom.

[0055] In this embodiment, the angle scale cooperates with the pointer to realize sliding the manual screw rod 502 to the corresponding angle, which is related to the number of holes drilled in the motor pressure plate. The sliding manual screw rod 502 is adjusted according to the distance requirement from the motor pressure plate drilling hole to the center of the motor pressure plate, thereby changing the distance between the positioning push rod 503 and the axis of the arc-shaped sliding hole. A conical rubber block of matching size is selected according to the hole radius, and the motor pressure plate is tightened by the conical rubber block, so that the drilling and grinding mechanism 6 is smoother and more accurately positioned when drilling and grinding the first hole. The conical rubber block extends into the hole and presses against the side of the hole to achieve effective limiting of the motor pressure plate.

[0056] The drilling and grinding mechanism 6 includes a cam divider 601, which is fixed to the lower end of the sliding block 304 on the right vertical sliding mechanism 3. A rotating plate 602 is fixed on the output shaft of the cam divider 601, and a drilling drive motor 603 and a grinding drive motor 604 are fixed to the lower end of the rotating plate 602, which are symmetrically arranged. A detachable drill bit 605 is provided at the lower end of the drilling drive motor 603, and a detachable grinding head 606 is provided at the lower end of the grinding drive motor 604.

[0057] In this embodiment, the cam divider 2 601 is used to drive the rotating plate 602 to rotate intermittently, thereby driving the drilling drive motor 603 and the grinding drive motor 604 to rotate intermittently. The drilling drive motor 603 is used to drive the drill bit 605 to drill the motor pressure plate, and the grinding drive motor 604 is used to drive the grinding head 606 to grind the drill hole to remove burrs on the edge of the hole, so as to facilitate the positioning of the conical rubber block on the hole. The drill bit 605 and the grinding head 606 can be replaced according to the process requirements of drilling and grinding the motor pressure plate.

[0058] The working principle of this utility model:

[0059] Preparation work: Select the positioning block 203 that matches the shape of the motor pressure plate, cooperate with the corresponding screw through the two adjustment blocks 302 on the right vertical sliding mechanism 3, and adjust the horizontal distance between the support member 301 and the motor pressure plate according to the distance requirement from the motor pressure plate drilling hole to the center of the motor pressure plate circle, thereby adjusting the drilling and grinding positions, and the angle scale cooperates with the pointer to achieve the sliding manual screw rod 502 to the corresponding angle, which is related to the number of holes drilled in the motor pressure plate. Adjust the sliding manual screw rod 502 according to the distance requirement from the motor pressure plate drilling hole to the center of the motor pressure plate circle, thereby changing the distance between the positioning push rod 503 and the axis of the arc-shaped sliding hole, select a suitable conical rubber block according to the hole radius, and replace the appropriate drill bit 605 and grinding head 606 according to the process requirements of drilling and grinding the motor pressure plate;

[0060] Turn on the air compressor and the air valve. The air compressor is responsible for providing wind power to the electric air valve. The electric air valve sends strong wind power to the drilling site through the blowing hose, blowing the drill chips generated by the drilling into the chip collection box 102, and placing the motor pressure plate on the rotating placement table 202 on the movable slider. The horizontal electric screw rod 201 transports the motor pressure plate on the rotating placement table 202 to the bottom of the electric clamping claw 403. For thin motor pressure plates or those without through holes inside, the inner side of the clamping claw can be used to clamp them. For motor pressure plates with through holes inside, the four clamping claws can be closed and pressed into the through holes to tighten the motor pressure plate, effectively limiting the motor pressure plate. The vertical electric screw rod 303 on the left drives the sliding block 304 to slide downward, and the motor pressure plate is tightened by the conical rubber block, so that the drilling and grinding mechanism 6 is more stable when drilling and grinding the first hole, and positioning is achieved. To be more precise, the right vertical electric screw member 303 drives the sliding block 304 to slide downward, and the drilling drive motor 603 drives the drill bit 605 to drill the motor pressure plate. After the drilling is completed, the right vertical electric screw member 303 drives the sliding block 304 to slide upward, thereby driving the drill bit 605 to reset, and the cam divider 601 drives the rotating plate 602 to rotate intermittently, thereby driving the drilling drive motor 603 and the grinding drive motor 604 to rotate intermittently, so that the grinding drive motor 604 is directly above the drill hole. The right vertical electric screw member 303 drives the sliding block 304 to slide downward, and the grinding drive motor 604 drives the grinding head 606 to grind the drilled hole. After the grinding is completed, the vertical electric screw member 303 drives the sliding block 304 to slide upward, thereby driving the grinding head 606 to reset. This is the drilling and grinding action.

[0061] The cam divider 401 drives the through-hole connector 402 to rotate a corresponding angle, thereby driving the electric clamping jaw 403 to rotate a corresponding angle (the quotient of 360° divided by the number of holes), thereby driving the motor pressure plate to rotate synchronously with the rotating placement table 202, so that the first hole of the motor pressure plate is opposite to the positioning push rod 503, and the positioning push rod 503 descends, extends into the hole through the conical rubber block and presses against the side of the hole, thereby effectively limiting the motor pressure plate, and repeating the drilling and grinding actions on the motor pressure plate;

[0062] After all holes are drilled, the drilling and grinding mechanism 6, the limiting mechanism 5 and the clamping mechanism 4 are reset, the air valve is closed, the horizontal electric screw member 201 drives the rotating placement table 202 to reset, and the motor pressure plate with the holes drilled is removed.

[0063] In summary, the clamping mechanism 4 cooperates with the horizontal conveying mechanism 2 to achieve accurate clamping and positioning of different types of motor pressure plates. At the same time, it cooperates with the left vertical sliding mechanism 3 to drive the motor pressure plate to rotate intermittently, which facilitates accurate drilling and high efficiency.

[0064] Adjust the horizontal distance between the right vertical sliding mechanism 3 and the horizontal conveying mechanism 2 according to the distance requirement from the motor pressure plate drill hole to the center of the motor pressure plate to adapt to different models of motor pressure plates;

[0065] Adjust the sliding manual screw rod 502 to the corresponding angle according to the number of holes to be drilled, and change the distance between the positioning push rod 503 and the axis of the arc-shaped sliding hole according to the distance between the motor pressure plate drilling hole and the center of the motor pressure plate circle, so as to accurately drill and position the motor pressure plate and adapt to different models of motor pressure plates;

[0066] The chip blowing mechanism 7 blows away the drill chips generated by drilling and grinding, making the positioning of the limit mechanism 5 more accurate, and at the same time cooperates with the stand mechanism 1 to realize the recovery of drill chips;

[0067] By rotating the placement table 202 and cooperating with the positioning block 203, the motor pressing plate is pressed against the positioning block 203, thereby achieving preliminary positioning of the motor pressing plate before drilling.

[0068] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
