Description

Technical Field

[0001] This utility model patent relates to the field of parts grinding technology, and mainly to a metal parts grinding device. Background Technology

[0002] Metal parts refer to the collective term for metal blocks, metal rods, metal tubes, etc. of various specifications and shapes manufactured from metal materials. Metal parts all have burrs and flash to varying degrees, and need to undergo a grinding process. Grinding is a commonly used semi-finishing and finishing method. The grinding wheel is the grinding tool for grinding. Grinding is the combined result of three actions: sliding, scratching, and cutting, performed by a large number of randomly distributed abrasive grains on the surface of the grinding wheel on the workpiece surface. Therefore, after grinding metal parts, a large number of metal chips will be produced, and these chips are numerous, small, and hard.

[0003] Currently, existing grinding devices have difficulty clamping metal tubes of different diameters, and when grinding the inner wall of the metal tube, it is difficult to remove the grinding debris from the metal tube, making it difficult to grind the bottom of the metal tube, which is not conducive to the processing of metal parts. To address this, we propose a metal parts grinding device. Utility Model Content

[0004] This utility model mainly provides a metal parts grinding device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the following technical solution is provided: a metal parts grinding device, including a processing table, a moving mechanism, and a grinding mechanism.

The drive end of the first motor is connected to the second gear.

[0006] The large bevel gear has a discharge hole at its center. The bottom end of the large bevel gear passes through the processing table and is located inside the collection box. The top of the large bevel gear is meshed with multiple small bevel gears. One side of the small bevel gear is connected to a first lead screw. One side of the first lead screw is connected to an L-shaped plate. The top side of the L-shaped plate is connected to a clamping plate.

[0007] The processing table is connected to a parts table at the top, and a metal tube is connected to the top of the parts table. A discharge pipe is fixed at the center of the parts table, and the bottom end of the discharge pipe is located inside the discharge hole.

[0008] Furthermore, the moving mechanism includes a second motor connected to one side of the top of the processing table, a second lead screw connected to the drive end of the second motor, and a C-shaped frame that is threadedly connected to one side of the second lead screw. A third motor is connected to one side of the top of the C-shaped frame, the drive end of the third motor is connected to the third lead screw, a moving block is threadedly connected to one side of the third lead screw, and a grinding mechanism is connected to the bottom of the moving block.

[0009] Furthermore, the clamp is arc-shaped, and a rubber pad is fixed to the side of the clamp near the metal tube.

[0010] Furthermore, the polishing mechanism includes a cylinder connected to the bottom of the movable block, a fixed plate connected to the driving end of the cylinder, a fourth motor connected to the bottom of the fixed plate, and a polishing wheel connected to the driving end of the fourth motor, wherein the diameter of the polishing wheel is larger than the diameter of the fixed plate.

[0011] Furthermore, the inner wall of the upper port of the discharge pipe is provided with a downwardly sloping edge, and the diameter of the top of the sloping edge is larger than the inner diameter of the metal pipe.

[0012] Furthermore, the top of the processing table is provided with multiple T-shaped grooves;

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a metal parts grinding device. A first motor drives a second gear to rotate, which in turn drives a first gear and a large bevel gear to rotate, which in turn drives multiple small bevel gears and a first lead screw to rotate. This causes the L-shaped plate and clamping plate to move, enabling the clamping of metal tubes of different diameters. During the grinding process, the grinding waste enters the discharge pipe, then the discharge hole, and finally falls into the collection box, thus cleaning the grinding waste out of the metal tube and preventing the waste from affecting the grinding of the metal tube when grinding the bottom of the metal tube.

[0022] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] For an example, please refer to... Figure 1-3 The metal parts grinding device includes a processing table 10, a moving mechanism 50, and a grinding mechanism 60. The bottom of the processing table 10 is provided with a material collection box 70, and the top of the processing table 10 is connected to a clamping device 20. The clamping device 20 includes a large bevel gear 24 rotatably connected to the top of the processing table 10, a first gear 23 connected to the bottom outer wall of the large bevel gear 24, a second gear 22 meshing with one side of the first gear 23, and a first motor 21 connected to the bottom of the processing table 10. The drive end of the first motor 21 is connected to the second gear 22.

[0024] The large bevel gear 24 has a discharge hole 241 at its center. The bottom end of the large bevel gear 24 passes through the processing table 10 and is located inside the collection box 70. The top of the large bevel gear 24 is meshed with multiple small bevel gears 25. One side of the small bevel gear 25 is connected to the first lead screw 26. One side of the first lead screw 26 is connected to the L-shaped plate 27. One side of the top of the L-shaped plate 27 is connected to the clamping plate 28.

[0025] The top of the processing table 10 is connected to the part table 30, the top of the part table 30 is connected to the metal tube 40, and the center of the part table 30 is fixed with the discharge tube 31, the bottom end of the discharge tube 31 is located inside the discharge hole 241.

[0026] It should be noted that in this embodiment, the parts platform 30 is used to support the metal tube 40. The first motor 21 drives the second gear 22 to rotate, which in turn drives the first gear 23 and the large bevel gear 24 to rotate, which in turn drives multiple small bevel gears 25 and the first lead screw 26 to rotate, thereby enabling the movement of the L-shaped plate 27 and the clamping plate 28 to clamp metal tubes 40 of different diameters. When grinding the inner wall of the metal tube 40, the grinding waste enters the discharge hole 241 through the discharge pipe 31 and finally falls into the collection box 70.

[0027] For an example, please refer to... Figure 2 The clamp 28 is arc-shaped, and a rubber pad 281 is fixed on the side of the clamp 28 closest to the metal tube 40.

[0028] It should be noted that in this embodiment, the arc-shaped clamp 28 improves the stability of the metal tube 40, and the rubber pad 281 can prevent the clamp 28 from leaving clamp marks on the surface of the metal tube 40.

[0029] For an example, please refer to... Figure 2-3 The moving mechanism 50 includes a second motor 51 connected to one side of the top of the processing table 10, a second lead screw 52 connected to the drive end of the second motor 51, and a C-shaped frame 53 that is threadedly connected to one side of the second lead screw 52. A third motor 54 is connected to one side of the top of the C-shaped frame 53. A third lead screw 55 is connected to the drive end of the third motor 54. A moving block 56 is threadedly connected to one side of the third lead screw 55. A grinding mechanism 60 is connected to the bottom of the moving block 56.

[0030] The polishing mechanism 60 includes a cylinder 61 connected to the bottom of the movable block 56, a fixed disk 62 connected to the drive end of the cylinder 61, a fourth motor 63 connected to the bottom of the fixed disk 62, and a polishing wheel 64 connected to the drive end of the fourth motor 63. The diameter of the polishing wheel 64 is larger than the diameter of the fixed disk 62.

[0031] It should be noted that in this embodiment, the second motor 51 drives the second lead screw 52 to rotate, thereby moving the C-shaped frame 53 to adjust the position of the grinding mechanism 60. The third motor 54 drives the third lead screw 55 to rotate, thereby moving the moving block 56 to adjust the position of the grinding mechanism 60, thus enabling the grinding mechanism 60 to move in the X and Y axis directions, so that the grinding wheel 64 contacts the inner wall of the metal tube 40. The fourth motor 63 drives the grinding wheel 64 to rotate, thereby achieving the grinding of the inner wall of the metal tube 40. The cylinder 61 drives the fixed plate 62 to rise and fall, thereby adjusting the height of the grinding wheel 64 and achieving all-round grinding of the inner wall of the metal tube 40.

[0032] Furthermore, the diameter of the grinding wheel 64 is larger than the diameter of the fixed plate 62, the driving end of the fourth motor 63, and the driving end of the cylinder 61, so as to prevent the grinding wheel 64 from having difficulty contacting the inner wall of the metal tube 40.

[0033] For an example, please refer to... Figure 2-3 The inner wall of the upper end of the discharge pipe 31 is provided with a downwardly inclined side 32, and the diameter of the top of the inclined side 32 is larger than the inner diameter of the metal pipe 40.

[0034] It should be noted that in this embodiment, the bevel 32 not only enlarges the upper port of the discharge pipe 31, making it easier to discharge waste chips, but also facilitates the sliding of the polished waste chips into the discharge pipe 31, preventing waste chips from accumulating on the parts table 30.

[0035] For an example, please refer to... Figure 3 The top of the processing table 10 is provided with multiple T-shaped slides 11.

[0036] A T-shaped slider 271 is fixed to the bottom of the L-shaped plate 27, and the T-shaped slider 271 is slidably connected to the groove of the T-shaped slide 11.

[0037] It should be noted that in this embodiment, the T-shaped slider 271 and the T-shaped groove 11 cooperate to improve the stability of the L-shaped plate 27 and prevent the L-shaped plate 27 from rotating with the first lead screw 26.

[0038] The specific operation method of this utility model is as follows:

[0039] The aforementioned metal parts grinding device first places the metal tube 40 on the parts table 30, and then drives the second gear 22 to rotate through the first motor 21, thereby driving the first gear 23 and the large bevel gear 24 to rotate, which in turn drives multiple small bevel gears 25 and the first lead screw 26 to rotate, thereby moving the L-shaped plate 27 and the clamping plate 28 to clamp the metal tube 40.

[0040] The grinding wheel 64 is rotated by the fourth motor 63, thereby grinding the inner wall of the metal tube 40. The second screw 52 is rotated by the second motor 51, thereby moving the C-shaped frame 53 to adjust the position of the grinding mechanism 60. The third screw 55 is rotated by the third motor 54, thereby moving the moving block 56 to adjust the position of the grinding mechanism 60. This allows the grinding mechanism 60 to move in the X and Y axes, so that the grinding wheel 64 contacts different positions on the inner wall of the metal tube 40. The fixed plate 62 is raised and lowered by the cylinder 61 to adjust the height of the grinding wheel 64, thus achieving all-round grinding of the inner wall of the metal tube 40. During the grinding process, the grinding debris enters the discharge hole 241 through the discharge pipe 31 and finally falls into the collection box 70.

[0041] The above embodiments merely illustrate the implementation methods of this application. However, those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
