Description

Technical Field

[0001] This utility model belongs to the field of hinge technology, and relates to polishing, particularly a polishing mechanism for the production of automotive door hinges. Background Technology

[0002] A polishing machine for automotive door hinge production is a type of machinery specifically designed for surface treatment and polishing of hinges to improve their durability, appearance, and corrosion resistance. This machine typically includes polishing equipment, an automated control system, a feeding and discharging system, and safety precautions. Through these functions, the polishing machine ensures that the hinge surface is smooth and flawless, thereby enhancing the overall quality of the product and its market competitiveness.

[0003] However, some existing polishing mechanisms can only polish one side of the hinge at a time, which requires operators to frequently adjust the hinge position to polish the other side, increasing the complexity and labor intensity of the operation. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a polishing mechanism for automobile door hinge production. The technical problem this utility model aims to solve is that only one side of the hinge can be polished at a time, which requires operators to frequently adjust the hinge position in order to polish the other side, increasing the complexity of operation and labor intensity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A polishing mechanism for manufacturing automotive door hinges includes an operating table. The top of the operating table has three tracks arranged side-by-side. Each track has a polishing opening. Two polishing strips are symmetrically arranged inside each of the three polishing openings, and these strips cooperate with the polishing openings. A rotating mechanism for rotating the polishing strips is provided on one side of each of the two polishing strips. Support plates are fixedly connected to the inside of the operating table near the two polishing strips. Adjusting plates are fixedly connected to the surfaces of the support plates near the polishing strips, and these plates cooperate with the polishing strips. A storage box is fixedly connected to the top of the operating table near the polishing openings. Placement slots are provided at the bottom of the storage box near the three tracks, and these slots cooperate with the tracks. A moving mechanism for moving the hinge is provided at the bottom of each of the three placement slots. Pressure plates are slidably connected inside each of the three placement slots. A constraint mechanism for restraining the pressure plates is provided at the top of each of the three pressure plates. The arrangement of the two polishing strips ensures that both sides of the hinge can be polished simultaneously.

[0006] As a further embodiment of this utility model, the rotating mechanism includes four rollers, all of which are rotatably connected to one side of the operating table. The four rollers are arranged in pairs, and the two grinding belts are respectively fitted onto the surfaces of the two sets of rollers. A motor is fixedly connected inside the operating table, and a third synchronous pulley is fixedly connected to the output shaft of the motor. A second synchronous pulley is fixedly fitted onto the end of one of the rollers near the third synchronous pulley. The same second synchronous belt is fitted onto the surfaces of the second and third synchronous pulleys. A first synchronous pulley is fixedly fitted onto the surfaces of the two rollers away from the second synchronous pulley, and the same first synchronous belt is fixedly fitted onto the surfaces of the two first synchronous pulleys. By setting the first synchronous belt, the two grinding belts can rotate synchronously.

[0007] As a further embodiment of this utility model, the moving mechanism includes a push plate, which is slidably connected to the inside of the track and is configured to cooperate with the placement groove. A connecting plate is fixedly connected to the end of the push plate away from the grinding belt. Two electric push rods are symmetrically fixedly connected to the surface of the connecting plate near the push plate, and both electric push rods are fixedly connected to the inside of the operating table. By setting the push plate, the hinge of the storage box can be moved.

[0008] As a further embodiment of this utility model, the constraint mechanism includes a connecting rod, which is fixedly connected to the top of the pressure plate. A pull plate is fixedly connected to the top of the connecting rod. Four limiting rods are fixedly connected to the top of the storage box, and the four limiting rods are evenly arranged in a square shape. The pull plate is slidably sleeved on the surface of the four limiting rods. A limiting plate is fixedly connected to the top of each of the four limiting rods. A spring is sleeved on the surface of each of the four limiting rods. The bottom ends of the four springs are fixedly connected to the top of the pull plate, and the top ends of the four springs are fixedly connected to the bottom of the limiting plate. By setting the springs, the pressure plate can be constrained.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model employs a technical solution of simultaneously grinding the hinge using two grinding belts. This ensures that both sides of the hinge can be ground at the same time, effectively solving the problem of only being able to grind one side of the hinge at a time, which requires operators to frequently adjust the hinge position to grind the other side, increasing the complexity and labor intensity of the operation. Two grinding belts are installed at the center of the track, and the two grinding belts are symmetrically arranged. Two electric push rods are installed on one side of the storage box, and the two electric push rods are connected to the push plate through a connecting plate. Because the push plate slides inside the track, when the electric push rod drives the push plate to move, it can push the bottom hinge, so that it can contact the grinding belt to achieve the purpose of grinding. An adjusting plate is also installed inside the two grinding belts, and the adjusting plate is designed to cooperate with the grinding belt. Because the adjusting plate is slightly protruding, when the grinding belt contacts it, it will also protrude synchronously, thus ensuring that the grinding belt can make closer contact with the hinge.

[0013] Reference Figure 1 - Figure 4 A polishing mechanism for manufacturing automotive door hinges includes an operating table 1. Three tracks 101 are arranged side-by-side on the top of the operating table 1. Each track 101 has a polishing opening 102. Two polishing belts 3 are symmetrically arranged inside each polishing opening 102, and the two polishing belts 3 cooperate with the polishing openings 102. A rotating mechanism for rotating the polishing belts 3 is provided on one side of each of the two polishing belts 3. Support plates 301 are fixedly connected to the inside of the operating table 1 near the two polishing belts 3. Adjusting plates 302 are fixedly connected to the surfaces of the support plates 301 near the polishing belts 3, and the adjusting plates 302 are connected to the polishing belts 3. The worktable 1 is designed to work together with a storage box 103 fixedly connected to the top of the side of the worktable 1 near the grinding port 102. The bottom of the storage box 103 near the three rails 101 is provided with a placement slot 104. The three placement slots 104 are designed to work together with the rails 101. The rails 101 can constrain the hinge. The bottom of the three placement slots 104 is provided with a moving mechanism for moving the hinge. The pressure plate 205 is slidably connected inside the three placement slots 104. The top of the three pressure plates 205 is provided with a constraint mechanism for constraining the pressure plate 205. The two grinding belts 3 can ensure that both sides of the hinge can be ground at the same time.

[0014] Preferably, the rotating mechanism includes four rollers 303, all of which are rotatably connected to one side of the operating table 1. The four rollers 303 are arranged in pairs. Two grinding belts 3 are respectively fitted onto the surfaces of the two sets of rollers 303. A motor 307 is fixedly connected inside the operating table 1. A third synchronous pulley 308 is fixedly connected to the output shaft of the motor 307. A second synchronous pulley 306 is fixedly fitted onto the end of one of the rollers 303 near the third synchronous pulley 308. The same second synchronous belt 309 is fitted onto the surfaces of the second synchronous pulley 306 and the third synchronous pulley 308. A first synchronous pulley 304 is fixedly fitted onto the surface of each of the two rollers 303 away from the second synchronous pulley 306. The same first synchronous belt 305 is fixedly fitted onto the surfaces of the two first synchronous pulleys 304. The first synchronous belt 305 enables the two grinding belts 3 to rotate synchronously.

[0015] Preferably, the moving mechanism includes a push plate 105, which is slidably connected to the inside of the track 101. The push plate 105 and the placement groove 104 are configured to cooperate with each other. A connecting plate 106 is fixedly connected to the end of the push plate 105 away from the grinding belt 3. Two electric push rods 107 are symmetrically fixedly connected to the surface of the connecting plate 106 near the push plate 105. Both electric push rods 107 are fixedly connected to the inside of the operating table 1. The hinge of the storage box 103 can be moved by the push plate 105.

[0016] Preferably, the constraint mechanism includes a connecting rod 204, which is fixedly connected to the top of the pressure plate 205. A pull plate 2 is fixedly connected to the top of the connecting rod 204. Four limiting rods 201 are fixedly connected to the top of the storage box 103, and the four limiting rods 201 are evenly arranged in a square shape. The pull plate 2 is slidably sleeved on the surface of the four limiting rods 201. A limiting plate 202 is fixedly connected to the top of each of the four limiting rods 201. A spring 203 is sleeved on the surface of each of the four limiting rods 201. The bottom end of each of the four springs 203 is fixedly connected to the top of the pull plate 2, and the top end of each of the four springs 203 is fixedly connected to the bottom of the limiting plate 202. The pressure plate 205 can be constrained by the setting of the springs 203.

[0017] Working principle: In use, the pull plate 2 is first pulled. A storage box 103 is located at the bottom of the pull plate 2, and a pressure plate 205 is installed inside the storage box 103. The pressure plate 205 is connected to the pull plate 2 via a connecting rod 204. Therefore, when the pull plate 2 is pulled, the pressure plate 205 can move, ensuring that the hinge to be polished can be placed into the placement slot 104. A track 101 is provided on the top of the operating table 1, and the track 101 cooperates with the placement slot 104. Thus, after the hinge is placed, the bottom hinge is inside the track 101. Two polishing belts 3 are installed at the center of the track 101, and the two polishing belts 3 are symmetrically arranged. Two electric push rods 107 are installed on one side of the storage box 103, and the two electric push rods 107 are connected to the push plate 105 via a connecting plate 106. Because the push plate 105 slides inside the track 101, when the electric push rods 107... When the pusher 105 moves, it can push the bottom hinge so that it can contact the polishing belt 3 to achieve the purpose of polishing. An adjustment plate 302 is also installed inside the two polishing belts 3. The adjustment plate 302 is set to cooperate with the polishing belt 3. Because the adjustment plate 302 is slightly protruding, it will also protrude synchronously when the polishing belt 3 contacts it, so as to ensure that the polishing belt 3 can contact the hinge more tightly. Since the hinge passes through the middle of the two polishing belts 3, both sides of the hinge can be polished simultaneously. When the hinge at the front end is being polished, the electric pusher 107 will drive the pusher 105 to reset. After it is reset, the hinge in the placement groove 104 will also fall down. After it falls down, the pusher 105 will push the subsequent hinge again. And the subsequent hinge will push the hinge being polished during the movement to complete the unloading work.
