A high-precision wheel hub hole finishing equipment

Abstract

This invention discloses a high-precision wheel hub hole finishing equipment, which relates to the field of drilling technology. When a wheel hub is positioned and fixed by clamping, the top of the hub cannot be guaranteed to be parallel to the horizontal plane. This causes the drill bit and mounting hole to shift during drilling, rendering the mounting hole unusable. By using a pressure cover in conjunction with the drill bit, the pressure cover contacts the hub first during the downward drilling process. Driven by a hydraulic cylinder, the pressure between the pressure cover and the hub is gradually increased before the drill bit contacts the hub. Before drilling the mounting hole, the deformation of the spring and the limiting post restrict the slide plate, ensuring that the bottom of the pressure cover remains parallel to the horizontal plane. Furthermore, by prioritizing contact with the hub, the tilt of the hub is adjusted before drilling, improving the fixing effect and preventing the drilling position from shifting due to the hub's tilt.

Description

Technical Field

[0001] This invention relates to the field of drilling technology, specifically to a high-precision wheel hub hole finishing equipment. Background Technology

[0002] Wheel hubs are an important component of vehicles such as automobiles and motorcycles. They are the intermediate devices connecting the tires and axles, supporting the tires, transmitting power and torque, fixing the tire's position, maintaining the correct tire shape and size, and ensuring the stability and safety of the vehicle. Wheel hub hole precision machining equipment is used to perform high-precision machining on the holes on wheel hubs to meet the fitting accuracy requirements of the hub and axles and other components. Among them, the machining of hub mounting holes is a key process in the hub manufacturing process, and its accuracy directly affects the assembly reliability of the hub with the axle and bolts and the vehicle's driving safety.

[0003] When drilling the mounting holes of the wheel hub, the top of the wheel hub cannot be guaranteed to be parallel to the horizontal plane when the wheel hub is positioned and fixed by clamping. This causes the position of the drill bit and the mounting hole to shift during drilling, resulting in the mounting hole being unusable after drilling. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A high-precision wheel hub hole finishing equipment, comprising:

[0006] The frame has a hydraulic cylinder fixedly installed on its top and a support plate fixedly installed inside the frame.

[0007] A clamping mechanism is used to fix and position the wheel hub to be processed, and the clamping mechanism is installed on the top of the support plate;

[0008] A filter material mechanism for collecting drill cuttings, wherein the filter material mechanism is installed at the bottom of a support plate;

[0009] A sliding plate is slidably mounted on the inner wall of the frame. The top of the sliding plate is fixedly connected to the output end of a hydraulic cylinder. A top plate is fixedly mounted on the outer side of the sliding plate, located directly above the clamping mechanism. A motor is fixedly mounted on the top of the top plate, with the motors evenly spaced along the center of the top plate. The output end of the motor passes through the top plate and extends to its bottom. A tool holder is fixedly mounted on the output end of the motor, and a drill bit is fixedly mounted on the bottom of the tool holder. A fixed plate is fixedly mounted on the top of the top plate, and limit posts are fixedly mounted on the bottom of the fixed plate, with the limit posts evenly spaced along the center of the fixed plate. A sliding disc is slidably mounted on the outer side of the limit posts, and a spring is fixedly mounted between the sliding disc and the fixed plate. A pressure cover is fixedly installed at the bottom of the sliding plate. The pressure cover cooperates with the drill bit. When drilling downwards, the pressure cover first contacts the hub. Through the driving force of the hydraulic cylinder, the pressure between the pressure cover and the hub is gradually increased before the drill bit contacts the hub. Before drilling the mounting hole of the hub, the deformation of the spring and the limitation of the limiting post on the sliding plate make the bottom end of the pressure cover always parallel to the horizontal plane. By prioritizing contact with the hub, the tilt of the hub is adjusted before drilling. This improves the fixing effect and avoids the drilling position shift due to the tilt of the hub during drilling. The bottom of the pressure cover is lower than the bottom end of the drill bit. The pressure cover is located outside the drill bit, and the outer side of the pressure cover is evenly provided with slots. The outer diameter of the pressure cover gradually increases from top to bottom.

[0010] Preferably, the clamping mechanism includes a slag guide cylinder and a support frame. The bottom ends of both the slag guide cylinder and the support frame are fixedly connected to the top of the support plate, and the support frame is located outside the slag guide cylinder. The outer diameter of the slag guide cylinder gradually decreases from top to bottom, and a washer is fixedly installed at the top of the slag guide cylinder. Through the cooperation of the washer and the slag guide roller, the hub is supported when it is placed in. At the same time, the washer, in conjunction with the pressure cover, presses down on the hub, fixing and reinforcing the hub during drilling to prevent the hub from moving during drilling, which would cause the drilling position to shift and affect the subsequent installation and use of the hub. The slag guide cylinder assists the filter mechanism in guiding the drilling debris to smoothly enter the filter mechanism. A grooved plate is fixedly installed at the top of the support frame. The top of the grooved plate has evenly spaced notches, and a cylinder is installed at the bottom of the grooved plate. A buckle is fixedly installed on the outside of the cylinder, and the cylinder is fixedly installed at the bottom of the grooved plate by the buckle.

[0011] Preferably, a connecting plate is fixedly installed at the notch of the slot. The bottom of the outer side of the connecting plate is fixedly connected to the output end of the cylinder. A slider is fixedly installed on the side of the connecting plate away from the cylinder. Slide grooves are opened on both sides of the slider. Elastic rings are engaged in the slide grooves of the slider. Through the cooperation of the elastic rings and the side slide rod, when clamping the hub, the concave side of the hub is used to apply pressure to the hub at an angle downward, so that the bottom of the hub is in close contact with the pad ring, avoiding the uneven height of the two sides of the hub and causing tilting. At the same time, the slider and the hub are isolated by a rubber block to avoid damage to the hub during clamping. A side slide rod is slidably installed at the end of the slider groove away from the cylinder. The end of the side slide rod away from the slider is inclined downward. A rubber block is fixedly installed at the end of the slider away from the cylinder.

[0012] Preferably, the filter cake mechanism includes a bottom ring, which is fixedly installed at the bottom of the support plate. An outer cover is fixedly installed at the bottom of the bottom ring, and an outlet pipe is fixedly installed at the bottom of the outer cover. An inner groove and a through-hole are fixedly installed at the bottom of the bottom ring. Through the cooperation of the inner groove and the through-hole, when filtering debris in the cutting fluid, large debris is concentrated in the inner groove, preventing large debris from contacting the filter bag and preventing large, sharp debris generated by drilling from contacting the filter bag and tearing it, thus reducing the filtration effect. At the same time, the debris is graded. Through holes are evenly opened on the outer side of the through-hole, and the through-hole is located outside the inner groove with a gap. The through-hole is located inside the outer cover.

[0013] Preferably, the outer side of the inner tank is uniformly provided with grid grooves, and a conical disk is fixedly installed at the bottom of the inner wall of the inner tank. The top of the conical disk is uniformly provided with liquid guiding holes. A filter bag is fixedly installed on the inner wall of the through-hole cylinder. The outer cover cylinder consists of upper and lower sections, with the outer diameter of the lower section being larger than that of the upper section. A conical cover is fixedly installed on the inner wall of the lower section of the outer cover cylinder. Through the cooperation of the conical cover and the magnetic ring, before the cutting fluid is discharged, the magnetic ring adsorbs fine debris, improving the separation effect between the cutting fluid and the debris. Simultaneously, the change in the outer diameter of the conical cover, in conjunction with the top guide groove, allows the cutting fluid to overflow outwards, allowing the debris to settle at the bottom due to its own gravity, preventing it from overflowing. The outer diameter of the conical cover gradually increases from top to bottom, and a guide groove is uniformly provided at the top of the conical cover. A magnetic ring is fixedly installed on the inner wall of the conical cover.

[0014] This invention provides a high-precision wheel hub hole finishing equipment. It has the following advantages:

[0015] I. This high-precision wheel hub hole machining equipment, through the cooperation of the pressure cover and the drill bit, when drilling downwards, the pressure cover contacts the wheel hub first. Through the driving force of the hydraulic cylinder, the pressure between the pressure cover and the wheel hub is gradually increased before the drill bit contacts the wheel hub. Before drilling the mounting hole of the wheel hub, the deformation of the spring and the limitation of the sliding plate by the limiting post make the bottom end of the pressure cover always parallel to the horizontal plane. By prioritizing contact with the wheel hub, the tilt of the wheel hub is adjusted before drilling. While improving the fixing effect, it avoids the drilling position deviation caused by the tilt of the wheel hub during drilling.

[0016] II. This high-precision wheel hub hole machining equipment, through the cooperation of the washer ring and the slag guide roller, provides a certain support for the wheel hub when it is placed in. At the same time, the washer ring, together with the pressure cover, presses down on the wheel hub to fix and reinforce it during drilling, preventing the wheel hub from moving during drilling and causing the drilling position to deviate, which would affect the later installation and use of the wheel hub. The slag guide roller assists the slag filter mechanism to guide the drilling debris and make it smoothly enter the slag filter mechanism.

[0017] Third, this high-precision wheel hub hole machining equipment uses an elastic ring and a side slide rod to clamp the wheel hub. When clamping the wheel hub, the side slide rod applies pressure to the wheel hub at an angle downwards, making the bottom of the wheel hub in close contact with the pad ring. This prevents the wheel hub from tilting due to different heights on both sides. At the same time, the slider and the wheel hub are isolated by a rubber block to prevent damage to the wheel hub during clamping and fixing.

[0018] IV. This high-precision wheel hub hole machining equipment uses an inner groove cylinder and a through-hole cylinder to concentrate large pieces of debris in the inner groove cylinder when filtering cutting fluid. This prevents large pieces of debris from contacting the filter bag and avoids large, sharp debris generated during drilling from contacting the filter bag, tearing the filter bag, and reducing the filtration effect. At the same time, the debris is graded.

[0019] V. This high-precision wheel hub hole finishing equipment, through the cooperation of a conical cover and a magnetic ring, uses the magnetic ring to adsorb fine debris before the cutting fluid is discharged, thereby improving the separation effect between the cutting fluid and the debris. At the same time, the outer diameter of the conical cover changes and cooperates with the guide groove at the top to allow the cutting fluid to be conducted outward by overflow, so that the debris can settle at the bottom by its own gravity and cannot overflow. This, together with the magnetic ring, improves the separation effect. Attached Figure Description

[0031] 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.

[0032] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution:

[0033] A high-precision wheel hub hole finishing equipment, comprising:

[0034] The frame 1 has a hydraulic cylinder 6 fixedly installed on its top and a support plate 8 fixedly installed inside the frame 1.

[0035] The clamping mechanism 3 is used to fix and position the wheel hub to be processed, and the clamping mechanism 3 is installed on the top of the support plate 8.

[0036] The filter material mechanism 4 is used to collect drill cuttings, and the filter material mechanism 4 is installed at the bottom of the support plate 8.

[0037] A sliding plate 5 is slidably installed on the inner wall of the frame 1. The top of the sliding plate 5 is fixedly connected to the output end of the hydraulic cylinder 6, and a top plate 2 is fixedly installed on the outer side of the sliding plate 5. The top plate 2 is located directly above the clamping mechanism 3, and a motor 7 is fixedly installed on the top of the top plate 2. When the motor 7 and the hydraulic cylinder 6 are started, the motor 7 drives the drill bit 14 to rotate through the tool holder 13. At the same time, the hydraulic cylinder 6 drives the sliding plate 5 to move down, causing the top plate 2 to move down, and driving the drill bit 14 closer to the hub to drill a hole in the hub. During the drilling process, the drilling location is flushed by an external cutting fluid delivery device. The debris is drawn into the filter mechanism 4, where it is filtered. Motor 7 is evenly installed along the center of the top plate 2, with its output end penetrating the top plate 2 and extending to its bottom. A tool holder 13 is fixedly installed at the output end of motor 7, and a drill bit 14 is fixedly installed at the bottom of the tool holder 13. As the top plate 2 moves downward, the bottom of the pressure cover 9 is lower than the bottom of the drill bit 14, causing the pressure cover 9 to contact the hub first. After contacting the hub, the position of the hub is adjusted. When the hub tilts, the driving force of the hydraulic cylinder 6 gradually increases. The contact pressure between the pressure cover 9 and the wheel hub, combined with the limiting post 11 restricting the slide plate 15, causes the slide plate 15 to restrict the pressure cover 9, making the bottom of the pressure cover 9 parallel to the horizontal plane. A fixed plate 10 is fixedly installed on the top of the top plate 2, and a limiting post 11 is fixedly installed on the bottom of the fixed plate 10. The limiting posts 11 are evenly installed along the center position of the fixed plate 10, and the slide plate 15 is slidably installed on the outer side of the limiting post 11. A spring 12 is fixedly installed between the slide plate 15 and the fixed plate 10. When contacting the wheel hub, the position of the wheel hub is adjusted by the contact pressure, so that the installation... The drilling position of the hole is perpendicular to the drill bit 14. Then, driven by the hydraulic cylinder 6, the contact pressure between the pressure cover 9 and the hub gradually increases, causing the slide plate 15 to compress the spring 12. During the continuous downward movement of the top plate 2, the bottom end of the drill bit 14 gradually becomes lower than the bottom end of the pressure cover 9 and contacts the hub, drilling the hub. The bottom of the slide plate 15 is fixedly installed with the pressure cover 9, and the bottom of the pressure cover 9 is lower than the bottom end of the drill bit 14. The pressure cover 9 is located outside the drill bit 14, and the outer side of the pressure cover 9 is evenly provided with slots. The outer diameter of the pressure cover 9 gradually increases from top to bottom.

[0038] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 7As shown, the clamping mechanism 3 includes a slag guide cylinder 301 and a support frame 302. The bottom ends of both the slag guide cylinder 301 and the support frame 302 are fixedly connected to the top of the support plate 8. The support frame 302 is located outside the slag guide cylinder 301. The outer diameter of the slag guide cylinder 301 gradually decreases from top to bottom. A washer ring 303 is fixedly installed at the top of the slag guide cylinder 301, and a grooved plate 304 is fixedly installed at the top of the support frame 302. When placing the wheel hub, the operator places the wheel hub on top of the slag guide cylinder 301. The washer ring 303 contacts the bottom of the wheel hub to support it. Then, the cylinder 305 is activated, causing the cylinder 3... The output end of 05 drives the slider 306, causing the slider 306 to slide within the notch of the slot 304 and move closer to each other. During the approach process, the end of the side slide rod 310 away from the slider 306 first contacts the outer side of the hub. Utilizing the arc-shaped depression at the center of the outer side of the hub, the side slide rod 310 tilts downwards at the end away from the slider 306. The top of the slot 304 has notches evenly distributed, and the bottom of the slot 304 is equipped with a cylinder 305. A buckle 307 is fixedly installed on the outside of the cylinder 305, and the cylinder 305 is fixedly installed at the bottom of the slot 304 through the buckle 307.

[0039] A connecting plate 308 is fixedly installed at the notch of the groove in the tray 304. The bottom of the outer side of the connecting plate 308 is fixedly connected to the output end of the cylinder 305. A slider 306 is fixedly installed on the side of the connecting plate 308 away from the cylinder 305. Sliding grooves are opened on both sides of the slider 306. As the slider 306 gradually approaches the wheel hub, it causes the side sliding rod 310 to compress the elastic ring 309 and deform, causing the side sliding rod 310 to slide. At the same time, it increases the clamping pressure with the wheel hub, thereby increasing the wheel's clamping force. The contact pressure between the hub and the washer ring 303 is then gradually increased by the slider 306, which gradually drives the rubber block 311 to contact the hub, thus fixing the hub. Each groove of the slider 306 is fitted with an elastic ring 309, and a side slide rod 310 is slidably installed at the end of the slider 306 away from the cylinder 305. The end of the side slide rod 310 away from the slider 306 is inclined downward, and the end of the slider 306 away from the cylinder 305 is fixedly installed with the rubber block 311.

[0040] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 10As shown, the filter mechanism 4 includes a bottom ring 42, which is fixedly installed on the bottom of the support plate 8. An outer cover cylinder 41 is fixedly installed on the bottom of the bottom ring 42, and a discharge pipe 44 is fixedly installed on the bottom of the outer side of the outer cover cylinder 41. An inner groove cylinder 43 and a through-hole cylinder 46 are fixedly installed on the bottom of the bottom ring 42. The cutting fluid carries the drilling debris into the interior of the inner groove cylinder 43 through the slag guide cylinder 301. Large pieces of debris are blocked by the grid groove of the inner groove cylinder 43, so that the large pieces of debris are concentrated in the inner groove cylinder 43 with the cooperation of the conical disk 48 and the inner groove cylinder 43. Small pieces of debris and... The cutting fluid passes through the guide hole and the grid groove, and enters the space between the through-hole cylinder 46 and the inner groove cylinder 43. Through the through hole of the through-hole cylinder 46 and the filter bag 47, small pieces of debris in the cutting fluid are blocked, allowing the cutting fluid to pass through the filter bag 47 and enter the interior of the outer cover cylinder 41 through the through hole of the through-hole cylinder 46. It flows downward along the outer cover cylinder 41, enters the lower end of the outer cover cylinder 41, and is concentrated on the inner side of the conical cover 45. The through-hole cylinder 46 has through holes evenly distributed on its outer side, and the through-hole cylinder 46 is located outside the inner groove cylinder 43 with a gap. The through-hole cylinder 46 is located inside the outer cover cylinder 41.

[0041] The outer side of the inner tank cylinder 43 is uniformly provided with grid grooves, and a conical disk 48 is fixedly installed at the bottom of the inner wall of the inner tank cylinder 43. The top of the conical disk 48 is uniformly provided with liquid guiding holes. A filter bag 47 is fixedly installed on the inner wall of the through-hole cylinder 46. The outer cover cylinder 41 is composed of two sections of cylinder, with the outer diameter of the lower cylinder being larger than that of the upper cylinder. A conical cover 45 is fixedly installed on the inner wall of the lower section of the outer cover cylinder 41. The conical shape of the conical cover 45, in conjunction with the magnetic ring 49, allows the magnetic ring 49 to adsorb extremely small debris that cannot be filtered out, causing the cutting fluid to overflow from the notch at the top of the conical cover 45 and be discharged through the outlet pipe 44. The outer diameter of the conical cover 45 gradually increases from top to bottom, and a guide groove is uniformly provided at the top of the conical cover 45. A magnetic ring 49 is fixedly installed on the inner wall of the conical cover 45.

[0042] In use, the hub to be drilled and precision machined is placed into the equipment, and the hub is clamped and fixed by the clamping mechanism 3. At the same time, the hub position is positioned so that it is in the center position. Then, the motor 7 and the hydraulic cylinder 6 are started, so that the motor 7 drives the drill bit 14 to rotate through the tool holder 13. At the same time, the hydraulic cylinder 6 drives the slide plate 5 to move down, so that the top plate 2 moves down, and drives the drill bit 14 to approach the hub to drill the hub. During the drilling process, the drilling position is flushed by the external cutting fluid delivery device, and the debris is carried into the slag filter mechanism 4 for filtration.

[0043] During the downward movement of the top plate 2, the bottom of the pressure cover 9 is lower than the bottom of the drill bit 14, causing the pressure cover 9 to contact the hub first. After contacting the hub, the position of the hub is adjusted. When the hub tilts, the driving force of the hydraulic cylinder 6 gradually increases the contact pressure between the pressure cover 9 and the hub. In conjunction with the limiting post 11 restricting the slide plate 15, the slide plate 15 restricts the pressure cover 9, making the bottom of the pressure cover 9 parallel to the horizontal plane. When contacting the hub, the contact pressure adjusts the position of the hub, making the drilling position of the mounting hole perpendicular to the drill bit 14. Subsequently, driven by the hydraulic cylinder 6, the contact pressure between the pressure cover 9 and the hub gradually increases, causing the slide plate 15 to compress the spring 12. During the continuous downward movement of the top plate 2, the bottom of the drill bit 14 gradually becomes lower than the bottom of the pressure cover 9 and contacts the hub, performing drilling on the hub.

[0044] In the clamping mechanism 3, when placing the wheel hub, the operator places the wheel hub on top of the guide cylinder 301. The hub is supported by the contact between the washer ring 303 and the bottom of the wheel hub. Then, the cylinder 305 is activated, causing the output end of the cylinder 305 to drive the slider 306. The slider 306 slides within the notch of the groove plate 304, moving closer to each other. During this approach, the end of the side slide rod 310 furthest from the slider 306 first contacts the outer side of the wheel hub, utilizing the arc at the center of the outer side of the wheel hub. The side slide rod 310 is inclined downwards at the end away from the slider 306. As the slider 306 gradually approaches the hub, the side slide rod 310 compresses the elastic ring 309, causing the side slide rod 310 to slide and increasing the clamping pressure with the hub. While clamping the hub, the contact pressure between the hub and the washer ring 303 is increased. Subsequently, the slider 306 gradually drives the rubber block 311 to contact the hub, gradually increasing the contact pressure between the rubber block 311 and the hub, thus fixing the hub.

[0045] In the slag filtering mechanism 4, the cutting fluid carries the drilling debris into the inner tank 43 through the guide tube 301. Large debris is blocked by the grid grooves of the inner tank 43, causing it to concentrate within the inner tank 43 under the cooperation of the conical disc 48 and the inner tank 43. Smaller debris and cutting fluid pass through the guide holes and grid grooves, entering the space between the through-hole tube 46 and the inner tank 43. The through-hole tube 46, in conjunction with the filter bag 47, filters the cutting fluid. Small debris in the cutting fluid is blocked, allowing the cutting fluid to pass through the filter bag 47 and enter the interior of the outer cover cylinder 41 through the through hole of the through hole cylinder 46. It flows downward along the outer cover cylinder 41 and enters the lower end of the outer cover cylinder 41, where it is concentrated inside the conical cover 45. The conical shape of the conical cover 45, in conjunction with the magnetic ring 49, adsorbs the extremely small debris that cannot be filtered out, causing the cutting fluid to overflow from the notch at the top of the conical cover 45 and be discharged through the outlet pipe 44.
