Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, specifically a grinding machine that is easy to use. Background Technology

[0002] A grinding machine is a machine tool used for precision machining of workpieces. It mainly uses a grinding wheel to cut the surface of materials. Grinding machines are characterized by high precision and high surface finish. The working principle of a grinding machine is to use the high-speed rotation of the grinding wheel to remove trace amounts of material from the surface of the workpiece through grinding force, thereby achieving dimensional control and surface treatment. Grinding machines are often used to process metal automotive parts. In actual processing, it is usually necessary to continuously grind all four sides of the workpiece. However, the included angles between adjacent sides of the workpiece are not all right angles. During the grinding process, it is necessary to rotate the workpiece at a specific angle so that the edge of the workpiece is facing the grinding wheel. Therefore, this application proposes a grinding machine that is easy to use. Summary of the Invention

[0004] The rotating mechanism includes an adjustable gear, a transmission structure, and a support plate. The adjustable gear includes a wheel and several gear tooth units. The wheel is fixedly installed at the output end of the drive device. The gear tooth units can be detachably installed along the circumference of the wheel and can form an intermittent fan-shaped surface, so that the adjustable gear can intermittently mesh with one end of the transmission structure within one rotation cycle. The transmission structure is used to transmit rotation to the other end to drive the support plate to rotate.

[0005] It also includes a grinding wheel body and a movable support. The movable support includes a slide rail, a slide base, a column and a telescopic arm. The slide rail is installed on the base, the slide base is slidably connected to the slide rail, the bottom of the column is fixedly connected to the slide base, and the telescopic arm is horizontally fixedly installed on the top of the column. The telescopic end of the telescopic arm is connected to the grinding wheel body.

[0006] Furthermore, the transmission structure includes a first auxiliary gear, a worm, a second auxiliary gear, and a rotating shaft. The first auxiliary gear is intermittently meshed with an adjustable gear for transmission. The shank of the worm is fixedly connected to the center of the first auxiliary gear, and the teeth of the worm are meshed with the second auxiliary gear for transmission. The rotating shaft is fixedly threaded through the center of the second auxiliary gear, and the top of the rotating shaft is fixedly connected to the center of the bottom of the support plate.

[0007] Furthermore, the fixing mechanism includes a reciprocating structure, a lifting structure, and a fixing plate. The reciprocating structure includes two synchronously rotating crown gears, a third auxiliary gear, a connecting shaft, and a first pulley. The teeth of the two crown gears are arranged facing each other, and the third auxiliary gear is arranged in the middle. The teeth of the two crown gears can mesh with the third auxiliary gear in sequence. The center of the third auxiliary gear and the first pulley are fixedly connected through the connecting shaft. The first pulley is connected to the lifting structure through a transmission belt. The bottom of the lifting structure is rotatably connected to the fixing plate.

[0008] Furthermore, the lifting structure includes a second pulley, a threaded sleeve, and a threaded rod. The second pulley is connected to the first pulley via a transmission belt. The inner wall of the second pulley is provided with an internal thread, and the lower part of the outer wall of the threaded sleeve is provided with an external thread. The threaded sleeve is threadedly connected to the inner hole of the second pulley. A limit structure is provided on the upper part of the threaded sleeve to prevent the threaded sleeve from rotating. The threaded sleeve is hollow and provided with an internal thread. The threaded rod is threadedly inserted into the threaded sleeve, and the lower end of the threaded rod is rotatably connected to a fixed plate.

[0009] Furthermore, the driving device includes a stepper motor and a mounting base. The stepper motor is mounted on the base via the mounting base, and two crown gears and a wheel are respectively mounted on the output end of the stepper motor.

[0010] Furthermore, a laser emitter is provided on one side of the wheel, and a laser receiver corresponding to the laser emitter is provided on the outer side of the crown gear.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1-8 As shown, it includes a base 1, on which a clamping device is provided. The clamping device includes a driving device 4, a rotating mechanism 2, and a fixing mechanism 3. The rotating mechanism 2 and the fixing mechanism 3 are respectively arranged, and both the rotating mechanism 2 and the fixing mechanism 3 are driven by the driving device 4.

[0029] The rotating mechanism 2 includes an adjustable gear 201, a transmission structure 202, and a support plate 203. The adjustable gear includes a wheel 201a and several gear tooth units 201b. The wheel 201a is fixedly installed at the output end of the drive device 4. The gear tooth units 201b can be detachably installed along the circumference of the wheel 201a and can form an intermittent fan-shaped surface, so that the adjustable gear 201 can intermittently mesh with one end of the transmission structure 202 within one rotation cycle. The transmission structure 202 is used to transmit rotation to the other end to drive the support plate 203 to rotate.

[0030] It also includes a grinding wheel body 5 and a movable support 6. The movable support 6 includes a slide rail 601, a slide base 602, a column 603 and a telescopic arm 604. The slide rail 601 is mounted on the base 1. The slide base 602 is slidably connected to the slide rail 601. The bottom of the column 603 is fixedly connected to the slide base 602. The telescopic arm 604 is horizontally fixedly mounted on the top of the column 603. The telescopic end of the telescopic arm 604 is connected to the grinding wheel body 5.

[0031] Before grinding the workpiece, several gear tooth units 201b are pre-installed on the grinding wheel 201a to form a fan-shaped surface according to the included angle between adjacent sides of the workpiece. The number of fan-shaped surfaces is consistent with the number of times the workpiece needs to be rotated. A certain gap is left between each fan-shaped surface. During operation, the workpiece is first placed on the support plate 203 with one side facing the grinding wheel body 5. The drive device 4 is started, which clamps the workpiece vertically through the fixing mechanism 3 to prevent the workpiece from moving during grinding. Then, the moving bracket 6 drives the grinding wheel body 5 to move to the side of the workpiece for grinding. After grinding, the moving bracket 6 removes the grinding wheel body 5. The drive device 4 continues to drive the grinding wheel 201a to rotate. The fan-shaped surfaces pre-set on the grinding wheel 201a are driven by meshing transmission. The drive mechanism 202 rotates at a specific angle, intermittently adjusting the side of the workpiece so that it is directly facing the grinding wheel body 5. When the gap between the drive mechanism 202 and the fan-shaped surface is relative, the workpiece remains stationary. The moving bracket 6 moves the grinding wheel body 5 to the side of the workpiece for grinding. After grinding, the moving bracket 6 moves the grinding wheel body 5 away, and the drive device 4 drives the next gear tooth unit 201b to mesh with the drive mechanism 202, thereby rotating the workpiece and grinding the next side. After all sides of the workpiece have been ground, the drive device 4 can drive the fixing mechanism 3 away from and release the workpiece, removing the workpiece from the support plate 203 and placing the next workpiece to be processed to repeat the above actions.

[0032] The transmission structure 202 includes a first auxiliary gear 202a, a worm 202b, a second auxiliary gear 202c, and a rotating shaft 202d. The first auxiliary gear 202a is intermittently meshed with the adjustable gear 201. The shank of the worm 202b is fixedly connected to the center of the first auxiliary gear 202a, and the teeth of the worm 202b are meshed with the second auxiliary gear 202c. The rotating shaft 202d is fixedly threaded through the center of the second auxiliary gear 202c, and the top of the rotating shaft 202d is fixedly connected to the center of the bottom of the support plate 203.

[0033] Adjustable gear 201 meshes with first auxiliary gear 202a through a pre-set sector, and then transmits the action to second auxiliary gear 202c through worm gear 202b via meshing transmission. Second auxiliary gear 202c and support plate 203 rotate synchronously through rotating shaft 202d, thereby driving the workpiece to rotate. The meshing method between worm gear 202b and second auxiliary gear 202c can prevent second auxiliary gear 202c from transmitting rotation in the opposite direction to worm gear 202b, achieving self-locking and preventing the workpiece from shifting position due to external force after the position is adjusted by rotation.

[0034] The fixing mechanism 3 includes a reciprocating structure 301, a lifting structure 302, and a fixing plate 303. The reciprocating structure 301 includes two synchronously rotating crown gears 301a, a third auxiliary gear 301b, a connecting shaft 301c, and a first pulley 301d. The teeth of the two crown gears 301a are arranged facing each other, and the third auxiliary gear 301b is arranged in the middle. The teeth of the two crown gears 301a can mesh with the third auxiliary gear 301b in sequence. The center of the third auxiliary gear 301b and the center of the first pulley 301d are fixedly connected through the connecting shaft 301c. The first pulley 301d is connected to the lifting structure 302 through a transmission belt 304. The bottom of the lifting structure 302 is rotatably connected to the fixing plate 303.

[0035] When the workpiece is placed on the support plate 203, the drive device 4 is activated. It first transmits power through the teeth of one of the crown gears 301a meshing with the third auxiliary gear 301b, and then through the connecting shaft 301c, the first pulley 301d, and the transmission belt 304. This transmits the action to the lifting structure 302, which in turn causes the lifting structure 302 to lower the fixed plate 303, thus clamping and fixing the workpiece vertically. The drive device 4 continues to rotate. After the entire side of the workpiece has been polished, the teeth of the other crown gear 301a mesh with the third auxiliary gear 301b, which in turn drives the third auxiliary gear 301b to rotate in the opposite direction. This causes the lifting structure 302 to raise the fixed plate 303, releasing the workpiece.

[0036] The lifting structure 302 includes a second pulley 302a, a threaded sleeve 302b, and a threaded rod 302c. The second pulley 302a is connected to the first pulley 301d via a transmission belt 304. The inner wall of the second pulley 302a is provided with an internal thread. The lower part of the outer wall of the threaded sleeve 302b is provided with an external thread. The threaded sleeve 302b is threadedly connected to the inner hole of the second pulley 302a. A limit structure 305 is provided on the upper part of the threaded sleeve 302b. The limit structure 305 is used to prevent the threaded sleeve 302b from rotating. The threaded sleeve 302b is hollow and provided with an internal thread. The threaded rod 302c is threadedly inserted into the threaded sleeve 302b. The lower end of the threaded rod 302c is rotatably connected to the fixed plate 303.

[0037] The reciprocating structure 301 transmits the motion to the lifting structure 302 via the transmission belt 304. The second pulley 302a rotates and drives the threaded sleeve 302b to move through the threaded connection. Since the limiting structure 305 prevents the threaded sleeve 302b from rotating, the threaded sleeve 302b can rise and fall. The adjustment is made by rotating the threaded rod 302c, so that the distance between the fixed plate 303 and the support plate 203 is more matched with the height of the workpiece.

[0038] The driving device 4 includes a stepper motor 401 and a mounting base 402. The stepper motor 401 is mounted on the base 1 via the mounting base 402. Two crown gears 301a and a wheel 201a are respectively mounted on the output end of the stepper motor 401.

[0039] Example 2

[0040] like Figure 7 and Figure 8 As shown, a laser emitter 7 is provided on one side of the wheel 201a, and a laser receiver 8 corresponding to the laser emitter 7 is provided on the outer side of the crown gear 301a. An optical path is formed between the laser emitter 7 and the laser receiver 8. The hubs of the two crown gears 301a and the wheel 201a are all made of transparent material. A light-shielding area 9 is provided in the projection of the teeth of the two crown gears 301a and in the middle of the projection. The fan-shaped surface formed by the gear tooth unit 201b has a light-shielding effect. Both the light-shielding area 9 and the fan-shaped surface can block the optical path. The laser receiver 8 can send a signal to the control unit when it receives the laser. The signal can drive the moving bracket 6 to move and move the grinding wheel body 5 closer to the workpiece for grinding.

[0041] Anti-slip buffer pads are provided on the opposing surfaces of the support plate 203 and the fixing plate 303. By providing anti-slip buffer pads, a buffer can be provided when the lifting structure 302 descends, so as to avoid pinching the workpiece.

[0042] Working principle: Before grinding the workpiece, several gear units 201b are pre-installed on the wheel 201a to form a fan shape according to the included angle between adjacent sides of the workpiece. The number of fan shapes is set to match the number of times the workpiece needs to be rotated. By installing the number of gear units 201b and adjusting the spacing between them, the rotation angle of the first gear 202a is precisely controlled. A certain gap is left between each fan shape. The adjustable gear 201 and the two crown gears 301a, projected clockwise from left to right, pass through the teeth of the inner crown gear 301a, the fan-shaped area of ​​the gear unit 201b, and the teeth of the outer crown gear 301a. There are gaps between the fan shape and the light-shielding area 9. The stepper motor 401 is started, and within one rotation cycle, the inner crown gear 301a drives the lifting structure 302 to descend and clamp the workpiece. The crown gear 301a and the adjustable gear 203 continue to rotate, and the laser is received by the laser receiver 8 through the gap and sends a signal to the control unit. The unit control moving bracket 6 drives the grinding wheel body 5 to move towards the side of the workpiece for grinding. Then, the drive device 4 continuously drives the wheel 201a to rotate. The fan-shaped surface pre-set on the wheel 201a drives the transmission structure 202 to rotate at a specific angle through meshing transmission. This intermittently rotates and adjusts the side of the workpiece so that it is directly facing the grinding wheel body 5. When the gap between the transmission structure 202 and the fan-shaped surface is relative, the workpiece can remain stationary. The moving bracket 6 drives the grinding wheel body 5 to move towards the side of the workpiece for grinding. After grinding, the moving bracket 6 removes the grinding wheel body 5. The drive device 4 then drives the fan-shaped surface formed by the next gear tooth unit 201b to mesh with the transmission structure 202, thereby driving the workpiece to rotate and grinding the next side. After all sides of the workpiece have been ground, the outer crown gear 301a drives the lifting structure 302 to rise under the drive of the stepper motor 401, releasing the workpiece. During this period, the laser is blocked by the light-shielding area 9. The next workpiece to be processed is then placed in, and the above actions are repeated.
