Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and specifically to an integrated grinding processing device for automotive parts. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts, and as people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturing plants have also developed rapidly. Due to technical and equipment limitations in the production process, automotive parts can usually only be processed into rough blanks, especially some ring-shaped parts (such as the outer and inner rings of bearings), which require precision machining using grinding equipment.

[0003] Currently available grinding equipment, when grinding ring-shaped components, requires fixing the ring to its own length. Therefore, it can typically only grind the outer or inner wall and one side of the ring. After grinding the outer or inner wall and one side, the ring needs to be turned over to grind the other side. Finally, the operator manually holds the ring against a grinding roller to grind the inner or outer wall, which is very cumbersome. Moreover, the equipment needs to be stopped when changing sides, resulting in low processing efficiency for ring-shaped components. Furthermore, the operator's manual grinding of the ring in the final step can easily lead to uneven grinding, rendering the ring unusable. This seriously delays the production of ring-shaped components and results in significant waste of production materials. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide an integrated grinding processing device for automotive parts. The device utilizes an electric push rod to move a rack upwards, which in turn drives a spur gear to rotate a double-acting screw and a lead screw. This allows control over the contact between the drive assembly and the annular component, facilitating simultaneous grinding of the inner and outer walls and both sides of the annular part. This improves the efficiency of grinding the annular component. Furthermore, the entire process eliminates the need for manual handling of the annular component during grinding, preventing uneven grinding that could render the annular component unusable and avoiding significant delays in production and material costs.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An integrated grinding processing device for automotive parts includes an operating table. A fixing mechanism is provided on the top surface of the operating table, and a grinding mechanism is provided between the fixing mechanism and the operating table. The fixing mechanism includes a clamping assembly, and a rotating assembly is provided inside the clamping assembly.

[0009] Furthermore, the grinding mechanism includes an adjustment component, with a drive component slidably connected to both ends of the adjustment component. The adjustment component includes a rectangular frame two and a rectangular frame three. A lead screw two is rotatably connected between the two short sides of the rectangular frame two. A bidirectional screw is rotatably connected between the two short sides of the rectangular frame three. A connecting rod is fixedly connected between the lead screw two and the adjacent end of the bidirectional screw. One end of the bidirectional screw passes through the side of the rectangular frame three and is fixedly connected to a spur gear four. An electric push rod two is fixedly connected to the top surface of the operating table. A rack that meshes with the spur gear four is fixedly connected to the output end of the electric push rod two.

[0010] Furthermore, the drive assembly includes two symmetrical sliders 1 that are screwed together with a bidirectional screw. One end of each slider 1 is rotatably connected to a rotating shaft 2. A grinding roller 1 is fixedly connected to the outer wall of the rotating shaft 2. A worm gear 2 is fixedly connected between the grinding roller 1 at the corresponding position on the outer wall of the rotating shaft 2 and the slider 1 at the corresponding position. An L-shaped connecting plate is fixedly connected to the side of the lower housing. A worm 2 that meshes with the two worm gears 2 is rotatably passed through the top of one side of the L-shaped connecting plate. A pulley 3 is fixedly connected to the other end of the worm 2. A motor 2 is connected to the top surface of the operating table. A pulley 4 that is driven by a belt 3 is fixedly connected to the output end of the motor 2.

[0011] Furthermore, the outer wall of the lead screw is screwed with a slider two, one end of the slider two is fixedly connected to an extension plate, a groove is provided on one side of the extension plate, both ends of the groove are slidably connected to slider three, one end of slider three is rotatably connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to a grinding roller two, a worm gear three is fixedly connected between the grinding roller two at the corresponding position on the outer wall of the rotating rod and the slider three at the corresponding position, a vertical plate is fixedly connected to one side of the bottom surface of the extension plate, a fixing block is fixedly connected to the side of the vertical plate, and both ends of the fixing block are rotatably connected to a worm gear three meshing with the worm gear three at the corresponding position.

[0012] Furthermore, one end of one of the worm gears three is fixedly connected to a bevel gear one, one end of the vertical plate is rotatably connected to a round rod fixed to the worm gear two, one end of the outer wall of the round rod is fixedly connected to a bevel gear two that meshes with the bevel gear one, and a double-headed cylinder is fixedly connected between the two sliders three.

[0013] Furthermore, both ends of the second and third rectangular frames are fixedly connected to the first rectangular frame at the corresponding positions by fixing plates.

[0014] The beneficial effects of this invention are:

[0015] 1. The rotation of the two lead screws can move the upper housing, thereby adjusting the distance between the two housings according to the size of the annular part. This allows for adjustment of the distance between the two upper rubber wheels and the two lower rubber wheels. The four rubber wheels can fix the annular part, thus preventing it from moving during grinding.

[0016] 2. The worm gear drives the two worm wheels to rotate. The rotating worm wheels can cause the two rubber wheels at the corresponding positions to rotate. Since the annular part is located between the four rubber wheels and the four rubber wheels are in close contact with the outer wall of the annular part, the four rotating rubber wheels can drive the annular part to rotate, thus facilitating the grinding operation of the annular part.

[0017] 3. Activating the electric actuator two causes the rack to move upwards. The upward movement of the rack causes the spur gear four to drive the double-acting screw and lead screw two to rotate. This controls the contact between the drive assembly and the annular component, facilitating simultaneous grinding of the inner and outer walls and both sides of the annular component. This improves the efficiency of grinding the annular component. Furthermore, the entire process eliminates the need for manual handling of the annular component during grinding, preventing uneven grinding that could render the annular component unusable and avoiding significant delays in production and material costs.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-9As shown, an integrated grinding processing device for automotive parts includes an operating table 1. A fixing mechanism 2 is provided on the top surface of the operating table 1. A grinding mechanism 3 is provided between the fixing mechanism 2 and the operating table 1. The fixing mechanism 2 includes a clamping assembly 21. A rotating assembly 22 is provided inside the clamping assembly 21. The clamping assembly 21 includes two symmetrical rectangular frames 211 fixed to the top surface of the operating table 1 and two vertically symmetrical housings 213. A lead screw is rotatably connected between the two short sides inside the rectangular frames 211. A connecting block 212 is screwed onto the outer wall of the lead screw. The two connecting blocks 212 are connected to... The upper housing 213 is fixedly connected to the side, and the lower housing 213 is fixedly connected to the top surface of the operating table 1. The bottom end of the lead screw 1 passes through the bottom surface of the operating table 1 and is fixedly connected to the pulley 214. The two pulleys 214 are connected by a belt. The rotation of the two lead screws 1 can move the upper housing 213, thereby adjusting the distance between the two housings 213 according to the size of the annular part. The two housings 213 can drive the rotating assembly 22 to fix the annular part, thereby preventing the annular part from moving during grinding.

[0031] A connecting frame 216 is fixedly connected between the top ends of the opposite sides of two rectangular frames 211. The rotating assembly 22 includes two sets of transmission components that rotate inside the housing 213 at corresponding positions. Each transmission component includes a rotating shaft that rotates between the opposite sides of the housing 213 at the corresponding positions. A rubber wheel 221 is fixedly connected to the outer wall of the rotating shaft. One end of the rotating shaft passes through the outer side of the housing 213 and is fixedly connected to a pulley 222. The two pulleys 222 inside the same housing 213 are connected by a belt drive. One end of the two symmetrical rotating shafts is fixedly connected to a worm gear 223. A worm 224 that meshes with the two worm gears 223 is rotatably connected between the operating table 1 and the connecting frame 216. The worm 224 drives the two worm gears 223 to rotate. The rotating worm gears 223 can cause the two rubber wheels 221 at corresponding positions to rotate. Since the annular component is located between the four rubber wheels 221, and the four rubber wheels 221 are connected to the... The outer walls of the annular components are in close contact, so the four rotating rubber wheels 221 can drive the annular component device. A spur gear 215 is fixedly connected to the bottom of the outer wall of one of the lead screws. The bottom end of the worm gear 224 passes through the bottom surface of the operating table 1 and is fixedly connected to a spur gear 225. A motor 226 is fixedly connected to the bottom surface of the cabinet inside the operating table 1. The output end of the motor 226 is fixedly connected to the worm gear 224. An electric actuator 227 is fixedly connected to the inner side of the cabinet inside the operating table 1. A fixed seat 228 is fixedly connected to the output end of the electric actuator 227. A spur gear 229 that meshes with spur gears 215 and 225 is rotatably connected inside the fixed seat 228. By starting the electric actuator 227, the meshing state of spur gear 229 with spur gears 225 and 215 can be controlled, thereby controlling the rotation of the two lead screws and preventing the continuous rotation of the four rubber wheels 221 from causing the two lead screws to rotate continuously.

[0032] The grinding mechanism 3 includes an adjustment assembly 31. Both ends of the adjustment assembly 31 are slidably connected to a drive assembly 32. The adjustment assembly 31 includes a second rectangular frame 311 and a third rectangular frame 312. A second lead screw 313 is rotatably connected between the two short sides of the second rectangular frame 311. A double-acting screw 314 is rotatably connected between the two short sides of the third rectangular frame 312. A connecting rod 315 is fixedly connected between the adjacent ends of the second lead screw 313 and the double-acting screw 314. One end of the double-acting screw 314 passes through the side of the third rectangular frame 312 and is fixedly connected to a fourth spur gear 316. An electric actuator 317 is fixedly connected to the top surface of the operating table 1. The output end of the electric actuator 317 is fixedly connected to... The rack 318, which meshes with the spur gear 316, can be moved upward by the activation of the electric actuator 317. The upward movement of the rack 318 can cause the spur gear 316 to drive the bidirectional screw 314 and the lead screw 313 to rotate, thereby controlling the contact between the drive assembly 32 and the annular component. This facilitates the drive assembly 32 to grind the inner and outer walls and two sides of the annular component simultaneously, improving the grinding efficiency of the annular component. Moreover, the entire process does not require the operator to manually hold the annular component for grinding, thus avoiding the annular component being scrapped due to uneven grinding and preventing serious delays in the production of the annular component and the cost of production materials.

[0033] The drive assembly 32 includes two symmetrical sliders 321 that are screwed into a bidirectional screw 314. One end of each slider 321 is rotatably connected to a rotating shaft 2. A grinding roller 322 is fixedly connected to the outer wall of the rotating shaft 2. A worm gear 3221 is fixedly connected between the grinding roller 322 at a corresponding position on the outer wall of the rotating shaft 2 and the slider 321 at the corresponding position. An L-shaped connecting plate 323 is fixedly connected to the side of the lower housing 213. A worm gear 3231, which meshes with the two worm gears 3221, is rotatably inserted through the top of one side of the L-shaped connecting plate 323. The other end of the worm gear 3231 is fixedly connected to a pulley 3232. A motor 324 is connected to the top surface of the operating table 1. The output end of motor 2 324 is fixedly connected to pulley 4 3241, which is driven by pulley 3 3232 via belt 3. Starting motor 2 324 causes worm gear 2 3231 to drive round rod 327 to rotate. The rotating worm gear 2 3231 causes two grinding rollers 1 322 to rotate. The two rotating grinding rollers 1 322 can perform grinding operations on the inner and outer walls of the annular component. Sliding slider 2 325 is screwed onto the outer wall of lead screw 2 313. One end of sliding slider 2 325 is fixedly connected to extension plate 3251. One side of extension plate 3251 has a groove. Both ends of the groove are slidably connected to sliding slider 3 326. One end of sliding slider 326 is rotatably connected to... A rotating rod has grinding rollers 3261 fixedly connected to its outer wall. A worm gear 3262 is fixedly connected between the grinding rollers 3261 at corresponding positions on the outer wall of the rotating rod and the slider 326 at corresponding positions. A vertical plate 3252 is fixedly connected to one side of the bottom surface of the extension plate 3251. A fixing block 3253 is fixedly connected to the side of the vertical plate 3252. Both ends of the fixing block 3253 are rotatably connected to worm gears 3262 at corresponding positions. The rotation of the worm gears 3263 drives the two grinding rollers 3261 to rotate. The two rotating grinding rollers 3261 can grind both sides of the annular component. One of the worm gears 3263... One end of 263 is fixedly connected to a bevel gear 3264. One end of the vertical plate 3252 is rotatably connected to a round rod 327 fixed to the worm gear 3231. One end of the outer wall of the round rod 327 is fixedly connected to a bevel gear 3271 that meshes with the bevel gear 3264. A double-headed cylinder 328 is fixedly connected between the two sliders 326. The double-headed cylinder 328 can control the two grinding rollers 3261 to contact the two sides of the annular component. The two ends of the rectangular frame 311 and the rectangular frame 312 are fixedly connected to the rectangular frame 211 at the corresponding position. The fixed plates 319 can limit and fix the rectangular frames 311 and 312.

[0034] Working principle: In use, the annular component is first placed on the two rubber wheels 221 located below, with the annular component positioned between the two grinding rollers 322. Then, by starting the motor 226, the worm gear 224 and spur gear 225 are rotated. The rotating worm gear 224 causes the two worm wheels 223 to drive the two pulleys 222 at corresponding positions to rotate. The rotating pulleys 222 cause the rubber wheels 221 at corresponding positions to rotate. Simultaneously, the rotating spur gear 225 causes the spur gear 3 229 to drive the spur gear 215 to rotate. The rotating spur gear 215 causes the two lead screws to rotate. The two rotating lead screws cause the upper housing 213 to move downwards. The downward movement of the housing 213 can... The two rubber wheels 221 at the corresponding positions are moved downwards until the two rubber wheels 221 at the top are in close contact with the annular component. Then, when the electric actuator 1 227 is activated, the spur gear 3 229 disengages from the spur gear 2 225 and the spur gear 1 215. At this time, the two lead screws stop, while the worm gear 1 224 still drives the four rubber wheels 221 to rotate. Since the four rubber wheels 221 are in close contact with the replacement component, the four rotating rubber wheels 221 can drive the annular component to rotate. Then, the electric actuator 2 317 is activated, which can move the rack 318 upwards. The upward-moving rack 318 can drive the spur gear 4 316 to drive the double-direction screw 314 and the lead screw 2 313 to rotate. The rotating double-direction screw 314 can drive the two grinding wheels to rotate. The grinding rollers 322 move closer together until they contact the inner and outer walls of the annular component. Simultaneously, the rotating lead screw 313 moves the extension plate 3251 closer to the annular component until the two grinding rollers 3261 are located on both sides of the annular component. At this point, the electric actuator 317 is closed, and the double-headed cylinder 328 is activated to move the two sliders 326 closer together, thus bringing the two grinding rollers 3261 closer together until they contact the two sides of the annular component. Then, the motor 324 is activated, causing the pulley 3241 to drive the pulley 3232 to rotate. The rotating pulley 3232 causes the worm gear 3231 and the round rod 327 to rotate. The rotating worm gear 3231... The device allows two grinding rollers 322 to rotate, grinding the inner and outer walls of the annular component. Simultaneously, a rotating rod 327 drives a bevel gear 3271, which in turn drives a bevel gear 3264. The bevel gear 3264 then drives a worm gear 3263, which in turn drives the two grinding rollers 3261, grinding both sides of the annular component. This device can simultaneously grind the outer wall, inner wall, and both sides of the annular component, improving the efficiency of grinding. Furthermore, the entire process eliminates the need for manual handling of the annular component, preventing uneven grinding and thus avoiding the scrapping of the annular part.This also avoids significant delays in the production of ring-shaped components and the associated costs of production materials.
