[0028] 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.

[0029] Please see Figures 1 to 8 This application provides a grinding device for irregularly shaped automotive parts, applied to irregularly shaped ear plates 5, such as... Figure 8 As shown, the irregular ear plate 5 includes a U-shaped connecting part and ear plates 52 disposed on opposite sides of the connecting part. The ear plate 52 has two first sides 521 disposed opposite to each other and a second side 522 connecting the two first sides 521. It includes: a machine base 1; a feeding mechanism 2 disposed on the machine base 1, which can reciprocate along a first direction; a fixing fixture 3 disposed on the feeding mechanism 2 for fixing the connecting part of the irregular ear plate 5; and a grinding mechanism 4 disposed on the machine base 1, located on one side of the feeding mechanism 2 along the first direction. The grinding mechanism 4 includes a rotatable drive shaft 41 and two first grinding components 42 and a second grinding component 43 disposed on the drive shaft 41. The second grinding component 43 is located between the two second grinding components 43 and is used to grind the second side 522 of the ear plate 52. The two first grinding components 42 can slide along the axial direction of the drive shaft 41. The two first grinding components 42 are respectively used to grind the two first sides 521 of the ear plate 52.

[0030] Specifically, the feeding mechanism 2 can be driven by a lead screw to reciprocate the irregular ear plate 5 along the first direction. The fixing fixture 3 includes a positioning seat and a clamping assembly. The positioning seat supports and positions the irregular ear plate 5, and the clamping assembly clamps and fixes the irregular ear plate 5.

[0031] In this application, the connecting part of the irregular part is fixed by the fixed tooling 3, and the irregular part is driven to reciprocate along the first direction by the feeding mechanism 2. The drive shaft 41 of the grinding mechanism 4 drives the first grinding component 42 and the second grinding component 43 to rotate. The second grinding component 43 grinds the second side 522 of the ear plate 52. The first side 521 on both sides is a bevel. The grinding of the two first grinding components 42 is completed by moving along the axial direction of the drive shaft 41. The grinding of the ear plate 52 can be completed in one feeding process, which can effectively free up manpower and improve work efficiency.

[0032] Currently, some irregularly shaped automotive parts include irregularly shaped ear plates 5. These ear plates 5 consist of a U-shaped connecting portion and ear plates 52 positioned on opposite sides of the connecting portion. Each ear plate 52 has two opposing first sides 521 and a second side 522 connecting the two first sides 521. Because the connection between the ear plate 52 and the connecting portion has a corner, and the two first sides 521 are beveled, grinding is inconvenient. Grinding must be done manually using a grinding machine, which is labor-intensive and inefficient.

[0033] In this application, the irregular ear plate 5 is simply fixed on the fixed fixture 3, and then the irregular ear plate 5 is fed by the feeding mechanism 2. The grinding mechanisms 4 on both sides grind the first side 521 through the first grinding component 42 and grind the second side 522 through the second grinding mechanism 4. Moreover, the first grinding component 42 can also move along the axial direction of the drive shaft 41 when grinding the first side 521, thereby ensuring the grinding effect of the first side 521.

[0034] In some embodiments, the grinding mechanism 4 further includes two elastic clamping components 44 sleeved on the drive shaft 41, the two elastic clamping components 44 abutting against the side of the two first grinding components 42 away from the second grinding component 43.

[0035] In this application, the first polishing component 42 is subjected to elastic thrust by the elastic clamping component 44, so that the first polishing component 42 can be tightly fitted with the first side 521 of the ear plate 52, thereby ensuring the polishing effect on the first side 521 of the ear plate 52.

[0036] In some embodiments, the drive shaft 41 has a transmission part 411, which is a prism. The first grinding assembly 42 includes: a sliding member 421, which is sleeved on the outer periphery of the transmission part 411; a sliding post 422 is embedded in the inner side of the sliding member 421; the sliding post 422 abuts against the transmission part 411; an abutting plate 423 is provided at one end of the sliding member 421 away from the second grinding assembly 43; and an elastic pressing assembly 44 abuts against the first grinding wheel 424, which is disposed on the outer periphery of the sliding member 421; and a first grinding surface 4241 is provided on the side of the first grinding wheel 424 facing the second grinding assembly 43.

[0037] In this application, the transmission part 411 of the drive shaft 41 has a prismatic structure. The sliding member 421 is sleeved on the outer periphery of the transmission part 411 and can slide along the axial direction of the drive shaft through the inner sliding column 422. Specifically, the sliding member 421 has a tubular structure and the interior of the sliding member 421 is a prismatic cavity. Multiple sliding columns 422 are respectively provided on each side of the cavity. Sliding columns 422 are respectively provided between the inner surface of the cavity and the outer surface of the prismatic prism, thereby ensuring the smoothness of the sliding member 421 sliding along the axial direction of the drive shaft 41. The abutment plate 423 is provided at one end of the sliding member 421, and the first grinding wheel 424 is provided at the other end of the sliding member 421. The abutment part abuts against the elastic pressing assembly 44. The first grinding wheel 424 grinds the first side 521 of the ear plate 52 through the first grinding surface 4241.

[0038] Specifically, a guide groove is provided along the axial direction on the outer surface of the prism, and a guide is provided on the inner surface of the sliding member 421. The guide is slidably disposed in the guide groove, thereby ensuring the reliability of the connection between the drive shaft 41 and the first grinding assembly 42 and ensuring the transmission effect.

[0039] In some embodiments, the distance between the two first sides 521 gradually narrows from the connecting portion to the second side 522, and the first polishing surface 4241 is an inclined surface arranged parallel to the first side 521.

[0040] In this application, the two first sides 521 are symmetrically arranged about the central axis, and the distance from the first side 521 to the central axis gradually decreases from the connecting part to the second side 522. This is to ensure the reliability of the ear plate 52 connection. However, this inclined structure is not convenient for grinding. By setting the first grinding surface 4241 as an inclined surface parallel to the first side 521, it can fully fit with the first side 521, thereby ensuring the grinding effect of the first side 521.

[0041] In some embodiments, the grinding mechanism 4 further includes two limiting components 45, which are slidably disposed on the machine base 1 along a first direction and are used to limit the two abutment plates 423 on one side facing the second grinding component 43.

[0042] In this application, the limiting component 45 can limit the abutment plate 423 and limit the minimum distance between the first polishing components 42. By adjusting the limiting component 45, that is, by sliding the limiting component 45 along the first direction, the extreme limiting position of the first polishing component 42 can be adjusted, that is, the minimum distance between the two first polishing components 42 can be adjusted, so as to ensure that the two first polishing components 42 can smoothly fit with the first side 521 of the ear plate 52 to complete the polishing in the initial stage.

[0043] In some embodiments, the limiting component 45 includes: a sliding block 451, which is slidably disposed on the machine base 1; a connecting rod 452, one end of which is connected to the sliding block 451 and the other end of which extends between the abutment plate 423 and the second grinding component 43; and a ball bearing 453, which is rotatably disposed at the end of the connecting rod 452 away from the sliding block 451, and the ball bearing 453 abuts against the abutment plate 423.

[0044] In this application, a fastening bolt is provided on the sliding block 451. The sliding block 451 can be locked and unlocked by rotating the fastening bolt. After unlocking, the slider can move along the first direction. The connecting rod 452 can make the sliding block 451 located outside the first grinding assembly 42, while the ball bearing 453 can limit the inner side of the abutment plate 423, which facilitates the adjustment of the sliding block 451.

[0045] In some embodiments, the drive shaft 41 has a threaded portion 412, and the elastic clamping assembly 44 includes: an adjusting nut 441, which is threadedly connected to the threaded portion 412 of the drive shaft 41; and an elastic member 442, which is sleeved on the outer periphery of the drive shaft 41, with both ends of the elastic member 442 abutting against the adjusting nut 441 and the abutment plate 423, respectively.

[0046] In this application, the position of the adjusting nut 441 on the drive shaft 41 can be adjusted by rotating the adjusting nut 441, thereby adjusting the compression of the elastic element 442, thus realizing the adjustment of the elastic force applied to the first grinding assembly 42. It can be adjusted according to the grinding situation during the grinding process to ensure the grinding effect of burrs.

[0047] In some embodiments, the second side 522 has an arc structure, and the second polishing assembly 43 includes: a mounting plate 431 disposed on the outer periphery of the drive shaft 41; and a second polishing wheel 432 disposed on the outer periphery of the mounting plate 431, wherein the outer periphery of the second polishing wheel 432 forms a second polishing surface 4321, and the second polishing surface 4321 is a concave surface that mates with the second side 522.

[0048] In this application, the second side 522 is configured as an arc structure, and the second side 522 is tangent to the first side 521. The first side 521 and the second side 522 are smoothly transitioned without any sharp corners. When the second grinding wheel 432 grinds the second side 522, the second side 522 is ground through the second grinding surface 4321 on the outer periphery of the second grinding wheel 432. Moreover, the second grinding surface 4321 has a concave structure, which can effectively cooperate with the second side 522 to complete the grinding of the second side 522.

[0049] In some embodiments, the first grinding wheel 424 is provided with an annular clearance groove 4242 on the side facing the second grinding wheel 432, the width of the second grinding wheel 432 is greater than the width of the mounting plate 431, and the end of the second grinding wheel 432 can enter the annular clearance groove 4242.

[0050] In this application, the first side 521 and the second side 522 are smoothly transitioned, but there is a transition between the first grinding wheel 424 and the second grinding wheel 432. By providing an annular relief groove 4242 on the first grinding wheel 424, the end of the second grinding wheel 432 can be inserted into the annular relief groove 4242, thereby ensuring effective grinding of the connection position of the first side 521 and the second side 522 and ensuring the grinding effect of the ear plate 52.

[0051] like Figure 3 and 4 As shown, in the initial stage of polishing, the connection between the first side 521 and the second side 522 can be polished using the first polishing surface 4241 of the first polishing wheel 424. Figure 5 As shown, as the polishing progresses, the ear plate 52 gradually moves closer to the second polishing wheel 432. Figure 6 As shown, until the second side 522 of the ear plate 52 contacts the second grinding surface 4321 of the second grinding wheel 432, the second grinding wheel 432 can grind the connection between the first side 521 and the second side 522, thereby ensuring the grinding effect at the connection between the first side 521 and the second side 522.

[0052] Specifically, at the junction of the first side 521 and the second side 522, the first grinding wheel 424 is used for initial grinding, and the second grinding wheel 432 is used for final grinding to ensure the grinding effect at the junction.

[0053] In some embodiments, the drive shaft 41 is rotatably mounted on the machine base 1 via bearings, and the grinding mechanism 4 further includes a drive assembly 46, the power output end of which is connected to the drive shaft 41.

[0054] In this application, the drive component 46 is a motor. The drive component 46 drives the drive shaft 41 to rotate, providing power for grinding, thereby completing the grinding operation.

[0055] The automotive irregular part grinding device uses a fixed fixture 3 to fix the connecting part of the irregular part. The feeding mechanism 2 drives the irregular part to move back and forth in the first direction. The drive shaft 41 of the grinding mechanism 4 drives the first grinding component 42 and the second grinding component 43 to rotate. The second grinding component 43 grinds the second side 522 of the ear plate 52. The first sides 521 on both sides are beveled. By moving the two first grinding components 42 along the axial direction of the drive shaft 41, the grinding of the two first sides 521 is completed. The grinding of the ear plate 52 can be completed in one feeding process, which can effectively free up manpower and improve work efficiency.
