Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a drilling equipment for machining assembly holes in the manufacture of shock absorber lifting rings. Background Technology

[0002] Shock absorbers are mechanical devices used to suppress vibration and buffer impacts. They are widely used in automobiles, motorcycles, bicycles, industrial equipment, medical devices, and other fields. Their core function is to reduce the amplitude of vibration when an object is in motion or under force, thereby improving stability, comfort, and safety. They usually work in conjunction with springs. When a vehicle is driving on an uneven road surface, the impact force of the road surface causes the spring to compress or extend in a reciprocating motion. The shock absorber can generate damping force through its internal structure to quickly "hold back" the spring's bounce and prevent the vehicle body from shaking violently up and down. The machining of the shock absorber's mounting hole directly affects the assembly accuracy, connection strength, and service life of the shock absorber. It is necessary to take into account dimensional accuracy, geometric tolerances, and surface quality. The mounting hole blank is usually formed by forging, casting, or cutting bar stock. In this case, the mounting hole needs to be pre-machined by drilling to leave a margin for subsequent finishing. Then, the hole is enlarged to complete the machining of the mounting hole. During the process of drilling holes in lifting ring materials, since the mounting holes of the lifting rings are through holes, the cutting tool needs to penetrate the lifting ring material during drilling. Once the cutting tool penetrates the material, if it comes into contact with a foreign object, the rotation of the drilling will be obstructed, the cutting tool will vibrate, causing the cutting tool to break, or the drilling accuracy will be affected by the vibration. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: A drilling device for machining assembly holes in the manufacture of shock absorber lifting rings, comprising: The frame has a sliding plate fixedly installed on its top, and a first cylinder fixedly installed on the outer side of the sliding plate. Side support plates are fixedly installed on both sides of the top of the frame. A clamping mechanism, which is mounted on the top of the side support plate; The drilling mechanism is slidably adapted to the inner wall of the slide plate, and the top of the drilling mechanism is fixedly connected to the output end of the first cylinder. The drilling mechanism is located directly above the clamping mechanism. An inner support plate is fixedly installed between the side support plates. The inner support plates are evenly installed between the side support plates, and a support bar is fixedly installed at the center of the top of the inner support plate. A sloping groove cylinder is fixedly installed at the center of the top of the support bar. Sloping grooves are evenly opened on the outer side of the sloping groove cylinder, and the sloping grooves of the sloping groove cylinder are inclined downward from the inside to the outside. An arc-shaped top ring is fixedly installed at the top of the sloping groove cylinder. The arc-shaped top ring cooperates with the sloping groove cylinder, and the bottom of the lifting ring material is in contact with the arc-shaped top ring to support the lifting ring material. At the same time, the bottom of the material at the drilling position provides space for the drilling tool to penetrate. This avoids the situation where the mounting hole of the lifting ring is a through hole, which would cause the tool to come into contact with foreign objects after penetrating the material during drilling, resulting in obstruction of drilling rotation, tool vibration, tool breakage, or error in drilling accuracy due to vibration. The top of the arc-shaped top ring is an arc-shaped convex surface at the center.

[0004] Preferably, the clamping mechanism includes a fixed frame, which is fixedly installed on the top of the side support plate. The fixed frame is symmetrically installed along the center of the frame axis, and a second cylinder is fixedly installed on both sides of the inner wall of the fixed frame. An inner slide bar is slidably installed between the fixed frames. The two ends of the outer side of the inner slide bar are fixedly connected to the output end of the second cylinder. A slot is opened at the center of the top of the inner slide bar, and a side plate is fixedly installed at the slot of the inner slide bar. The side plate cooperates with the inner pad, and the inclined surface of the side plate cooperates with the elastic material of the inner pad. After the inclined surface of the side plate contacts the lifting ring material, the position of the lifting ring material is adjusted by the clamping force to prevent the position of the lifting ring material from shifting. At the same time, the elastic material of the inner pad is deformed and buffered under the clamping pressure during clamping, providing an adjustment buffer distance for the position adjustment of the lifting ring material. A rectangular groove frame is slidably installed on the inner wall of the side plate, and an inner pad is fixedly installed between the rectangular groove frame and the side plate. The inner pad is made of elastic material.

[0005] Preferably, side clamping blocks are fixedly installed on opposite sides of the rectangular groove frame, and the side clamping blocks are symmetrically installed along the center position of the axis of the rectangular groove frame. The side of the side clamping block away from the rectangular groove frame is an inclined surface, and strip-shaped protrusions are evenly provided on the inclined surface of the side clamping block. An inclined pressure block is fixedly installed at the center position of the top of the rectangular groove frame. Through the cooperation of the inclined pressure block and the rubber strip, the inclined pressure plate contacts the edge of the top of the lifting ring material during clamping. Under the clamping pressure, a downward pressure is applied to the lifting ring material to ensure the contact pressure between the bottom of the lifting ring and the arc-shaped top ring. This avoids the gap between the bottom of the lifting ring material and the arc-shaped top ring after clamping, which would cause the lifting ring material to tilt at the moment of contact during drilling, causing the drilling position to shift. The inclined pressure block is located between the side clamping blocks, and the end of the inclined pressure block away from the rectangular groove frame is inclined upward. A groove is opened at the center position of the bottom of the inclined pressure block, and a rubber strip is fixedly installed at the groove of the inclined pressure block. An arc-shaped groove is opened at the center position of the end of the inclined pressure block away from the rectangular groove frame.

[0006] Preferably, the drill bit mechanism includes a top plate, the outer side of which is slidably adapted to the inner wall of a sliding groove plate. The output end of the first cylinder is fixedly connected to the bottom of the top plate. A motor is fixedly connected to the top of the top plate, the output end of which penetrates the top plate and extends to its bottom. A connecting cylinder is fixedly connected to the output end of the motor. An annular groove is formed at the bottom of the connecting cylinder, and a bottom pad ring is fixedly installed at the annular groove. A tool holder is installed inside the connecting cylinder, and a drill bit is fixedly installed at the bottom of the tool holder. The top of the tool holder is conical, and its outer diameter gradually increases from top to bottom. An outer... The outer casing has an inner clamping sleeve rotatably mounted on its inner wall. This inner clamping sleeve engages with a side clamping plate. After the tool handle is inserted, rotating the first screw causes the side clamping plate to move inward, contacting the tool handle and increasing the contact pressure between the tool handle and the inner clamping sleeve. The inner clamping sleeve, in conjunction with the side clamping plate, clamps the tool handle, fixing it between the inner clamping sleeve and the side clamping plate, thus ensuring the tool handle is securely fixed. The inner wall of the connecting cylinder has a side clamping plate slidably mounted on it. A first screw is rotatably mounted on the outer side of the side clamping plate. The end of the first screw away from the side clamping plate passes through the connecting cylinder and extends to its outer side. The outer side of the first screw is threadedly connected to the inner wall of the connecting cylinder.

[0007] Preferably, a conical plate is slidably installed on the inner wall of the connecting cylinder, and the conical plate is evenly installed along the center position of the connecting cylinder. An inner pad plate, made of rubber material, is fixedly installed on the inner wall of the conical plate. The inner wall of the inner pad plate is tightly fitted to the top of the outer side of the tool holder. An inclined pressure plate is slidably installed on the inner wall of the connecting cylinder, and a pressure ring is slidably installed on the outer side of the conical plate. Through the cooperation of the pressure ring and the conical plate, after the tool holder is fixed, rotating the second screw causes the inclined pressure plates to move closer to each other, driving the pressure ring to move against the conical plate. The outer side moves downward and presses the conical plate inward, causing the conical plate to drive the inner pad plate to press the tool holder. The inner pad plate deforms under contact pressure, tightly adhering to the tool holder, increasing the friction between the inner pad plate and the tool holder. This prevents the drill bit from slipping due to drilling resistance during drilling, thus ensuring the normal operation of the drilling work. The bottom of the inclined pressure plate is an inclined surface, and the bottom of the inclined pressure plate is tightly fitted with the top of the pressure ring. The inclined pressure plate is symmetrically installed along the center position of the axis of the connecting cylinder, and a second screw is threadedly connected to the inner wall of the inclined pressure plate.

[0008] This invention provides a drilling device for machining assembly holes in the manufacture of shock absorber lifting rings. It has the following advantages: 1. The drilling equipment for machining the assembly holes of the shock absorber lifting ring uses an arc-shaped top ring and a slanted groove cylinder to cooperate. The arc-shaped top ring contacts the bottom of the lifting ring material to support the lifting ring material. At the same time, the bottom of the material at the drilling position provides space for the drilling tool to penetrate. This avoids the situation where the assembly hole of the lifting ring is a through hole, which would cause the tool to come into contact with foreign objects after penetrating the material during drilling, resulting in obstruction of drilling rotation, tool vibration, tool breakage, or errors in drilling accuracy due to vibration.

[0009] 2. The drilling equipment for machining the assembly holes of the shock absorber lifting ring uses a side clamping plate and an inner pad to cooperate. The inclined surface of the side clamping plate cooperates with the elastic material of the inner pad. After the inclined surface of the side clamping plate contacts the lifting ring material, the position of the lifting ring material is adjusted by the clamping force to prevent the lifting ring material from shifting. At the same time, the elastic material of the inner pad ring deforms and buffers under the clamping pressure during clamping, providing an adjustment buffer distance for the position adjustment of the lifting ring material.

[0010] 3. The drilling equipment for machining the assembly holes of the shock absorber's lifting ring uses a combination of a slanted pressure block and a rubber strip. During clamping, the slanted pressure plate contacts the top edge of the lifting ring material. Under clamping pressure, downward pressure is applied to the lifting ring material to ensure the contact pressure between the bottom of the lifting ring and the top ring. This prevents gaps from appearing between the bottom of the lifting ring material and the top ring after clamping, which could cause the lifting ring material to tilt at the moment of contact during drilling, resulting in a shift in the drilling position.

[0011] IV. The drilling equipment for machining the assembly hole of the shock absorber lifting ring, through the cooperation of the inner clasp and the side clamp, after the tool holder is installed, by rotating the first screw, the side clamp moves inward and contacts the tool holder, increasing the contact pressure between the tool holder and the inner clasp. Through the cooperation of the inner clasp and the side clamp, the tool holder is clamped and fixed between the inner clasp and the side clamp, ensuring the fixation of the tool holder.

[0012] V. The drilling equipment for machining the assembly holes of the shock absorber lifting ring, through the cooperation of the pressure ring and the conical plate, after the tool holder is fixed, by rotating the second screw, the inclined pressure plates are brought closer to each other, driving the pressure ring to move downward on the outside of the conical plate and pressing the conical plate inward. The conical plate drives the inner pad plate to press the tool holder, causing the inner pad plate to deform under the contact pressure, tightly adhering to the tool holder, increasing the friction between the inner pad plate and the tool holder, and preventing the drill bit from slipping due to drilling resistance when rotating the drill, thus affecting the normal progress of the drilling work.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: A drilling device for machining assembly holes in the manufacture of shock absorber lifting rings, comprising: The frame 1 has a slide plate 6 fixedly installed on its top, and a first cylinder 5 fixedly installed on the outer side of the slide plate 6. Side support plates 4 are fixedly installed on both sides of the top of the frame 1. Clamping mechanism 2 is installed on the top of side support plate 4; The drill mechanism 3 is slidably adapted to the inner wall of the slide plate 6, and the top of the drill mechanism 3 is fixedly connected to the output end of the first cylinder 5. The drill mechanism 3 is located directly above the clamping mechanism 2. An inner support plate 7 is fixedly installed between the side support plates 4. The inner support plates 7 are evenly installed between the side support plates 4, and a support strip 10 is fixedly installed at the center of the top of the inner support plate 7. When placing the lifting ring material, the lifting ring material is placed on the top of the arc-shaped top ring 8. The arc surface of the top of the arc-shaped top ring 8 contacts the bottom of the lifting ring material to support it. Then, the clamping mechanism 2 is activated to clamp and fix the lifting ring material on both sides. At the same time, the center position of the lifting ring material is adjusted so that the center position of the lifting ring material corresponds to the center position of the arc-shaped top ring 8. The arc-shaped top ring 8 supports the bottom of the lifting ring material. An inclined groove cylinder 9 is fixedly installed at the center of the top of the support strip 10. The outer side of the grooved cylinder 9 is uniformly provided with inclined grooves, and the inclined grooves of the grooved cylinder 9 slope downwards from the inside to the outside. An arc-shaped top ring 8 is fixedly installed on the top of the grooved cylinder 9. When the drilling mechanism 3 moves downwards to drill the material under the drive of the first cylinder 5, it supports the material and assists the drilling mechanism 3 in processing the assembly hole of the lifting ring material. At the same time, during the processing, since the assembly hole is a through hole, the arc-shaped top ring 8 cooperates with the grooved cylinder 9 to form a cavity at the center of the bottom of the lifting ring material while providing auxiliary support. This provides space for the cutting tool of the drilling mechanism 3 to penetrate the lifting ring material. At the same time, the inclined groove of the grooved cylinder 9 provides space for the discharge of the bottom hole debris. The top of the arc-shaped top ring 8 is an arc-shaped convex surface at the center.

[0017] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8As shown, the clamping mechanism 2 includes a fixed frame 21, which is fixedly installed on the top of the side support plate 4. The fixed frame 21 is symmetrically installed along the center position of the axis of the frame 1, and a second cylinder 22 is fixedly installed on both sides of the inner wall of the fixed frame 21. An inner slide bar 23 is slidably installed between the fixed frames 21. The two ends of the outer side of the inner slide bar 23 are fixedly connected to the output end of the second cylinder 22. In the clamping mechanism 2, when the lifting ring material is put in, the second cylinder 22 drives the inner slide bar 23 to move closer to each other between the fixed frames 21, so that the inner slide bar 23 passes through the side clamping plate 24. The rectangular groove frame 26 is driven, which in turn drives the side clamping block 27 and the inclined pressure block 28. The side clamping block 27 and the inclined pressure block 28 cooperate and contact both sides of the lifting ring material. The inclined surface of the side clamping block 27 is used to position and adjust the lifting ring material when clamping it. The center of the top of the inner slide bar 23 is provided with a slot, and a side clamping plate 24 is fixedly installed at the slot of the inner slide bar 23. The rectangular groove frame 26 is slidably installed on the inner wall of the side clamping plate 24. An inner pad 25 is fixedly installed between the rectangular groove frame 26 and the side clamping plate 24. The inner pad 25 is made of elastic material.

[0018] Side clamping blocks 27 are fixedly installed on opposite sides of the rectangular groove frame 26, and the side clamping blocks 27 are symmetrically installed along the center position of the axis of the rectangular groove frame 26. The side of the side clamping block 27 away from the rectangular groove frame 26 is inclined, and strip-shaped protrusions are evenly provided on the inclined surface of the side clamping block 27. An inclined pressure block 28 is fixedly installed at the center position of the top of the rectangular groove frame 26. The inclined pressure block 28 is located between the side clamping blocks 27, and the bottom of the inclined pressure block 28 contacts the edge of the top of the lifting ring material. Under clamping pressure, it presses the lifting ring material downward, cooperating with the support of the arc-shaped top ring 8 for the material. The lifting ring material is clamped and fixed. During the clamping and pressing process, the contact pressure between the side clamping block 27 and the material is transmitted to the inner pad block 25 through the rectangular groove frame 26, causing the inner pad block 25 to deform under pressure. This provides buffer space for the position adjustment of the lifting ring during clamping. The inclined pressure block 28 is inclined upward at the end away from the rectangular groove frame 26. A groove is opened at the center of the bottom of the inclined pressure block 28, and rubber strips 29 are fixedly installed at the groove of the inclined pressure block 28. An arc-shaped groove is opened at the center of the end of the inclined pressure block 28 away from the rectangular groove frame 26.

[0019] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 12As shown, the drill mechanism 3 includes a top plate 301. The outer side of the top plate 301 is slidably adapted to the inner wall of the slide plate 6. The output end of the first cylinder 5 is fixedly connected to the bottom of the top plate 301. A motor 302 is fixedly connected to the top of the top plate 301. The output end of the motor 302 passes through the top plate 301 and extends to its bottom. A connecting cylinder 303 is fixedly connected to the output end of the motor 302. An annular groove is formed at the bottom of the connecting cylinder 303, and a bottom pad ring 313 is fixedly installed at the annular groove of the connecting cylinder 303. A tool holder 304 is installed inside the connecting cylinder 303, and a drill bit 305 is fixedly installed at the bottom of the tool holder 304. The top of the tool holder 304 is conical, and its outer diameter gradually increases from top to bottom. An outer cover cylinder 310 is fixedly installed on the inner wall of the connecting cylinder 303. In the drill mechanism 3, the top plate 301 is fixedly connected to the output end of the first cylinder 5. After the lifting ring material is fixed, the top plate 301 is moved downward by the first cylinder 5 under the restriction of the slide plate 6, so that the top plate 301 is close to the lifting ring material. During the downward movement, the connecting cylinder 303 is driven to rotate by the motor 302, which in turn drives the tool holder 304 to rotate, causing the drill bit 305 installed at the bottom of the tool holder 304 to rotate at high speed. The drill bit 305 rotates at high speed and, after contacting the lifting ring material during the gradual downward movement, drills a hole in the lifting ring material. The inner wall of the outer cover cylinder 310 is rotatably installed with an inner clamping cylinder 311, and the inner wall of the connecting cylinder 303 is slidably installed with a side clamping plate 312. The outer side of the side clamping plate 312 is rotatably installed with a first screw 306. The end of the first screw 306 away from the side clamping plate 312 passes through the connecting cylinder 303 and extends to its outer side. The outer side of the first screw 306 is threadedly connected to the inner wall of the connecting cylinder 303.

[0020] A tapered plate 309 is slidably installed on the inner wall of the connecting cylinder 303, and the tapered plate 309 is evenly installed along the center position of the connecting cylinder 303. An inner pad 314 is fixedly installed on the inner wall of the tapered plate 309. The inner pad 314 is made of rubber and its inner wall is tightly fitted to the top of the outer side of the tool holder 304. An inclined pressure plate 307 is slidably installed on the inner wall of the connecting cylinder 303. When fixing the tool holder 304, after the tool holder 304 is inserted into the connecting cylinder 303, the worker rotates the first screw 306 to move the side clamping plate 312 inward, so that the side clamping plate 312 moves inward closer to the tool holder 304, so that the side clamping plate 312 cooperates with the inner clamping sleeve 311 to clamp the tool holder 304 on the outside, so that the tool holder 304 is tightly fitted to the inner clamping sleeve 311. Finally, the first screw 306 is rotated. The two screws 308 cause the inclined pressure plate 307 to slide on the inner wall of the connecting cylinder 303. At the same time, the inclined pressure plates 307 move closer to each other, pressing the pressure ring 315. The pressure ring 315 causes the conical plate 309 to move closer to each other, increasing the contact pressure between the inner pad plate 314 and the tool holder 304. Under the contact pressure, the inner pad plate 314 deforms and fits tightly against the tool holder 304, while increasing the friction between the inner pad plate 314 and the tool holder 304. The pressure ring 315 is slidably installed on the outer side of the conical plate 309. The bottom of the inclined pressure plate 307 is inclined, and the bottom of the inclined pressure plate 307 fits tightly against the top of the pressure ring 315. The inclined pressure plate 307 is symmetrically installed along the center position of the axis of the connecting cylinder 303. The inner wall of the inclined pressure plate 307 is threadedly connected to the second screw 308.

[0021] In use, the shock absorber lifting ring material to be drilled is placed into the equipment. The bottom of the lifting ring material is supported by the arc top ring 8 and clamped and fixed in cooperation with the clamping mechanism 2. Then, the first cylinder 5 drives the drill bit mechanism 3, which moves downward under the restriction of the slide plate 6 to contact the lifting ring material and perform drilling processing on the lifting ring material.

[0022] When placing the lifting ring material, the lifting ring material is placed on top of the arc-top ring 8. The arc surface of the top of the arc-top ring 8 contacts the bottom of the lifting ring material, supporting the lifting ring material. Then, the clamping mechanism 2 is activated, clamping and fixing the lifting ring material on both sides. At the same time, the center position of the lifting ring material is adjusted so that its center position corresponds to the center position of the arc-top ring 8. Simultaneously, the arc-top ring 8 supports the bottom of the lifting ring material. When the drilling mechanism 3 moves downward to drill the material under the drive of the first cylinder 5, it supports the material and assists the drilling mechanism 3 in processing the assembly hole of the lifting ring material. During processing, since the assembly hole is a through hole, the arc-top ring 8 cooperates with the inclined groove cylinder 9 to form a cavity at the center of the bottom of the lifting ring material while providing auxiliary support. This provides space for the cutting tool of the drilling mechanism 3 to penetrate the lifting ring material. At the same time, the inclined groove of the inclined groove cylinder 9 provides space for the discharge of the bottom drilling debris.

[0023] In the clamping mechanism 2, after the lifting ring material is placed in, the second cylinder 22 drives the inner slide bar 23 to move closer to each other between the fixed frames 21. The inner slide bar 23 drives the rectangular groove frame 26 through the side clamping plate 24, which in turn drives the side clamping block 27 and the inclined pressure block 28. The side clamping block 27 and the inclined pressure block 28 cooperate to contact both sides of the lifting ring material. The inclined surface of the side clamping block 27 is used to position and adjust the lifting ring material when clamping it. At the same time, the bottom of the inclined pressure block 28 contacts the top edge of the lifting ring material. Under clamping pressure, the lifting ring material is pressed downward. This cooperates with the support of the arc top ring 8 to clamp and fix the lifting ring material. During the clamping pressure process, the contact pressure between the side clamping block 27 and the material is transmitted to the inner pad block 25 through the rectangular groove frame 26, causing the inner pad block 25 to deform under pressure. This provides a buffer space for the position adjustment of the lifting ring during clamping.

[0024] In the drilling mechanism 3, the top plate 301 is fixedly connected to the output end of the first cylinder 5. After the lifting ring material is fixed, the first cylinder 5 drives the top plate 301 to move downward under the constraint of the slide plate 6, so that the top plate 301 approaches the lifting ring material. During the downward movement, the motor 302 drives the connecting cylinder 303 to rotate, which in turn drives the tool holder 304 to rotate, causing the drill bit 305 installed at the bottom of the tool holder 304 to rotate at high speed. The drill bit 305 rotates at high speed and, after contacting the lifting ring material during the gradual downward movement, drills a hole in the lifting ring material. When fixing the tool holder 304, after the tool holder 304 is inserted into the connecting cylinder 303, the worker rotates the first screw 306. The side clamping plate 312 moves inward, bringing it closer to the tool holder 304. This allows the side clamping plate 312 to engage with the inner clamping sleeve 311, clamping the tool holder 304 tightly against the inner clamping sleeve 311. Finally, the second screw 308 is rotated, causing the inclined pressure plate 307 to slide on the inner wall of the connecting sleeve 303. Simultaneously, the inclined pressure plates 307 move closer together, pressing the pressure ring 315. This causes the pressure ring 315 to move the conical plate 309 closer together, increasing the contact pressure between the inner pad 314 and the tool holder 304.
