[0035] Reference below Figures 1 to 10 The grinding device according to the embodiment of the utility model is described.

[0036] like Figures 1 to 3 As shown, the grinding device according to the embodiment of the utility model includes a mounting frame 100, a grinding spindle assembly 200, an adjusting mechanism 300 and a locking mechanism 400. The grinding spindle assembly 200 is rotatably connected to the mounting frame 100. The adjusting mechanism 300 connects the mounting frame 100 and the grinding spindle assembly, and is used to drive the grinding spindle assembly 200 to rotate relative to the mounting frame 100; the locking mechanism 400 includes a first driving assembly 410 and a locking assembly. The first driving assembly 410 is arranged on the mounting frame 100. The output end of the first driving assembly 410 is connected to the locking assembly, and is used to drive the locking assembly to lock the grinding spindle assembly 200 on the mounting frame 100 to limit the rotation of the grinding spindle assembly 200 relative to the mounting frame 100.

[0037] It can be understood that the grinding device includes a mounting frame 100, a grinding spindle assembly 200, an adjustment mechanism 300 and a locking mechanism 400; since the grinding spindle assembly 200 is rotatably connected to the mounting frame 100, when in use, the grinding spindle assembly 200 can be first rotated to a desired angle relative to the mounting frame to meet the needs of different deflection angles, and then the grinding spindle assembly 200 is locked by the locking mechanism 400 to prevent the grinding spindle assembly 200, which has been adjusted to the desired angle, from rotating relative to the mounting frame 100 again, affecting the grinding spindle assembly 200. grinding effect; specifically, the locking mechanism 400 includes a locking assembly and a first drive assembly 410, the locking assembly is connected to the output end of the first drive assembly 410, and can lock the grinding spindle assembly 200 on the mounting frame 100 under the drive of the first drive assembly 410, thereby limiting the shaking of the grinding spindle assembly 200 and further affecting the grinding accuracy; therefore, the grinding device of the present application has the advantages of automatically adjusting the angle of the grinding spindle assembly and locking the grinding spindle assembly 200, preventing the shaking of the grinding spindle assembly 200 from affecting the grinding accuracy, and improving the processing efficiency.

[0038] Specifically, in this embodiment, the grinding spindle assembly 200 is rotatably connected to the mounting frame 100 via the second bearing 120. It should be understood that in some other embodiments, the mounting frame 100 and the grinding spindle assembly 200 may be provided with arc portions and arc grooves 211 that are adapted to each other, so that the grinding spindle assembly 200 can also be rotated relative to the mounting frame 100 with the rotation axis fixed.

[0039] It can be understood that the locking assembly includes a first locking member 420 and a clamping limit portion 421. One end of the first locking member 420 is slidably connected to the mounting frame 100, and the other end is provided with a clamping limit portion 421. The grinding spindle assembly 200 is provided with a limit groove for the clamping limit portion 421 to slide and abut against. The first locking member 420 can slide between the unlocking position and the locking position under the drive of the first driving assembly 410. When the first locking member 420 is in the locked position, the clamping limit portion 421 abuts against the limit groove. For example, Figures 1 to 4As shown, in the present embodiment, the locking assembly includes a first locking member 420, one end of which is provided with a clamping limit portion 421, and the clamping limit portion 421 is slidably connected to the grinding spindle assembly 200 through the limit groove of the grinding spindle assembly 200, thereby enabling the first locking member 420 to avoid the rotating grinding spindle assembly 200; in addition, the other end of the first locking member 420 can also be slidably connected to the mounting frame 100, and can slide between a locking position and an unlocking position under the drive of the first driving assembly 410. When the first locking member 420 is in the locking position, the first locking member 420 abuts against the groove wall of the limit groove and presses it against the mounting frame 100 through the clamping limit portion 421, thereby achieving locking and fixing of the grinding spindle assembly 200.

[0040] It should be understood that in addition to the locking method in which the grinding spindle assembly 200 is pressed against the mounting frame 100 by a locking assembly in the above-mentioned embodiment, in some other embodiments, the locking assembly can also be a component similar to a car brake pad, which uses friction to hold the grinding spindle assembly 200 and thus achieve locking.

[0041] It can be understood that the grinding spindle assembly 200 includes a fixing plate 210, a limiting groove is provided on the fixing plate 210, the limiting groove is an arc groove 211, and the rotation axis of the grinding spindle assembly 200 rotating around the mounting frame 100 passes through the center of the circle corresponding to the arc groove 211. Figures 1 to 4 , Figure 7 As shown, in this embodiment, the grinding spindle assembly 200 includes a fixed plate 210 with a limit groove, the limit groove is arc-shaped, and the rotation axis of the grinding spindle assembly 200 relative to the mounting frame 100 is coaxial with the arc groove 211, so that when the grinding spindle assembly 200 rotates relative to the mounting frame 100, the clamping limit portion 421 of the first locking member 420 can be avoided.

[0042] Specifically, the cross section of the arc groove 211 can be set to be T-shaped, L-shaped or even conical, as long as the clamping limit portion 421 can be pressed against the side of the arc groove 211 close to the mounting frame 100 .

[0043] It can be understood that the locking assembly further includes a locking crank 430, the first end of which is rotatably connected to an end of the first locking member 420 away from the pressing limit portion 421, and the first end of the locking crank 430 is provided with a cam surface, and abuts against the mounting frame 100 through the cam surface, and the cam surface is provided with a working contour section 431, and in the rotation direction of the locking crank 430, the distance from the working contour section 431 to the rotation axis of the locking crank 430 changes gradually, and the first driving assembly 410 is drivingly connected to the locking crank 430 and is used to drive the locking crank 430 to rotate. For example, Figures 1 to 5As shown, in the present embodiment, the locking assembly also includes a locking crank 430, a first end of the locking crank 430 being rotatably connected to an end of the first locking member 420 away from the clamping limit portion 421, and a first end of the locking crank 430 being provided with a cam surface for abutting against the mounting frame 100, and a distance from a working contour segment 431 on the cam surface to a rotation axis of the locking crank 430 gradually changes, and at the same time, the locking crank 430 is drivably connected to the first driving assembly 410, so that the locking crank 430 can rotate under the drive of the first driving assembly 410, thereby causing the area of ​​the working contour segment 431 abutting against the mounting frame 100 to change. When the locking crank 430 is rotated, so that the distance from the area where the working contour segment 431 abuts the mounting frame 100 to the rotation axis of the locking crank 430 is smaller, the distance between the clamping limit portion 421 and the mounting frame 100 is larger, thereby enabling unlocking, and the grinding spindle assembly 200 can be rotated relative to the mounting frame 100 to adjust to a suitable angle; and when the distance from the area where the working contour segment 431 abuts the mounting frame 100 to the rotation axis of the locking crank 430 is larger, the distance between the clamping limit portion 421 and the mounting frame 100 is smaller, so that the clamping limit portion 421 presses the grinding spindle assembly 200 on the mounting frame 100, thereby achieving locking.

[0044] It can be understood that the locking crank 430 and the first driving assembly 410 are arranged on the side of the mounting frame 100 away from the grinding spindle assembly 200, and the mounting frame 100 is provided with a through hole 110, and the middle part of the first locking member 420 is passed through the through hole 110. Figures 1 to 5 As shown, in this embodiment, the first locking member 420 is inserted into the through hole 110 of the mounting frame 100, and the hole wall of the through hole 110 limits the first locking member 420 from rotating along with the locking crank 430, and can only slide along the through hole 110, so that the rotation of the locking crank 430 is converted into the sliding of the first locking member 420 along the through hole 110, thereby realizing the compression or relaxation of the grinding spindle assembly 200 by the clamping limiter 421. In addition, the locking crank 430 and the first drive assembly 410 are both arranged on the side of the mounting frame 100 away from the grinding spindle assembly 200, thereby avoiding the interference between the locking crank 430, the first drive assembly 410 and the rotation of the grinding spindle assembly 200.

[0045] It should be understood that, in addition to the form of providing the through hole 110 in the mounting frame 100, in some other embodiments, the mounting frame 100 may not be provided with the through hole 110, but the middle part of the first locking member 420 may be abutted against the lower edge of a plate of the mounting frame 100. In this way, during the process of rotating and locking the locking handle 430, the middle part of the first locking member 420 is abutted against the lower edge of the plate and cannot rotate with the locking handle 430, so that the first locking member 420 can only slide in a direction perpendicular to the fixed plate 210, thereby achieving locking.

[0046] It is understandable that the locking mechanism 400 further includes a linkage assembly 440, the linkage assembly 440 or the locking assembly is provided with a connection position, the linkage assembly 440 is connected to the locking assembly through the connection position, the linkage assembly 440 is connected to the output end of the first driving assembly 410, and can drive the locking assembly to rotate under the drive of the first driving assembly 410. For example, Figures 4 to 9 As shown, in the present embodiment, the locking mechanism 400 further includes a linkage assembly 440 connected between the locking assembly and the first drive assembly 410. The locking assembly or the linkage assembly 440 is provided with a connecting position, and the connection is achieved through the connecting position. Therefore, the driving force is transmitted with the aid of the linkage assembly 440, thereby reducing damage to the first drive assembly 410 and improving the service life of the first drive assembly 410.

[0047] It can be understood that the linkage assembly 440 also includes a slide plate 442 and an adjustment compensating member. The slide plate 442 is provided with a plurality of receiving grooves 4421. The locking crank 430 is inserted into the receiving grooves 4421. The slide plate 442 is connected to the output end of the first driving assembly 410 and can be translated under the drive of the first driving assembly 410 to drive the locking assembly to rotate through the groove wall of the receiving groove 4421. The adjustment compensating member is provided in the receiving groove 4421 and is used to abut against the locking crank 430. For example, Figures 4 to 9 As shown, in this embodiment, the linkage assembly 440 also includes a slide plate 442 and an adjustment compensation member. The slide plate 442 is provided with a plurality of receiving grooves 4421, and the locking crank handle 430 is inserted into the receiving groove 4421. The slide plate 442 slides under the drive of the first driving assembly 410, and drives the locking crank handle 430 to rotate through the connecting position, thereby achieving locking.

[0048] However, due to processing errors, the size of the receiving groove 4421 may not meet the use requirements. When the size of the receiving groove 4421 is too small, the locking crank 430 is locked in the receiving groove 4421, and it is difficult to rotate, and it is also difficult to adjust between locking and loosening; when the size of the receiving groove 4421 is too large, the sliding plate 442 may not be able to contact the locking crank 430 during the sliding process and rotate it to the locking position, making it difficult to lock. Therefore, in this embodiment, an adjustment compensating member is also provided, and the receiving groove 4421 can be appropriately processed to be larger. The adjustment compensating member is provided in the receiving groove 4421, and the connection position is formed between the groove wall of the receiving groove 4421 and the adjustment compensating member, so that the processing error of the receiving groove 4421 can be compensated by the adjustment compensating member.

[0049] Specifically, the slide plate 442 is slidably connected to the mounting frame 100 , and a guide rail is provided on the mounting frame 100 . The slide plate 442 can slide along the guide rail under the drive of the first driving assembly 410 .

[0050] Specifically, the cam surface is further provided with a base circle segment 432, and the distances from each point on the base circle segment 432 to the rotation axis of the locking crank 430 are equal, and the base circle segment 432 is connected to the position where the working profile segment 431 has the smallest distance to the rotation axis of the locking crank 430. The arrangement of the base circle segment 432 can also compensate for some machining errors of the receiving groove 4421 or deviations in the driving stroke of the first driving assembly 410, so that no matter where the base circle segment 432 abuts against the mounting frame 100, the grinding spindle assembly 200 can be unlocked.

[0051] It should be understood that, in addition to the above-mentioned embodiment in which the connection position is formed in the form of the accommodating groove 4421 of the slide plate 442, in some other embodiments, the connection position can also be set on the locking crank handle 430, and the locking crank handle 430 is provided with a strip groove along its own length direction, and the linkage component 440 is provided with a sliding pin, which is connected to the output end of the first drive component 410 and inserted in the strip groove. The sliding pin can move along the original sliding direction of the slide plate 442 under the drive of the first drive component 410, so that the sliding pin can also slide along the strip groove at the same time, thereby driving the rotation of the locking crank handle 430, and thus can also achieve locking or unlocking.

[0052] It can be understood that the adjustment and compensation member is an eccentric shaft 441, which is rotatably disposed in the receiving groove 4421, and the connection position is formed between the circumference of the eccentric shaft 441 and the groove wall of the receiving groove 4421. Figures 4 to 9 As shown, in this embodiment, the adjustment compensation member is set in the form of an eccentric shaft 441. By rotating the eccentric shaft 441, the degree to which the circumferential surface of the eccentric shaft 441 protrudes from the receiving groove 4421 is adjusted, thereby adjusting the size of the receiving position between the circumferential surface of the eccentric shaft 441 and the groove wall of the receiving groove 4421, thereby reasonably compensating the processing error of the receiving groove 4421 according to actual conditions.

[0053] Specifically, the linkage assembly 440 further includes a third locking member 443 , which connects the eccentric shaft 441 and the slide plate 442 and is used to lock the eccentric shaft 441 to the slide plate 442 .

[0054] It should be understood that the adjustment compensating member can not only be adjusted to the required position before use to compensate for the processing error of the accommodating groove 4421, but also as use progresses, when the wear of the working contour segment 431 of the cam surface of the locking crank handle 430 increases and the locking effect can no longer be achieved, the degree to which the adjustment compensating member protrudes from the connection position can be adjusted, thereby adjusting the degree of deflection of the locking crank handle 430, so that the area of ​​the working contour segment 431 that is farther from the rotation axis of the locking crank handle 430 is put into use, thereby extending the service life of the locking mechanism 400.

[0055] It should be understood that, in addition to the structural form of the eccentric shaft 441 in the present embodiment, the adjustment compensating part can also be set to any other structure, and the adjustment compensating part can be replaced and the adjustment compensating part of suitable size can be installed in the receiving groove 4421 of the slide plate 442, so as to meet the locking and unlocking needs in the present application scheme; in other embodiments, the size of the connection position can also be adjusted by adjusting the length of the adjustment compensating part exposed in the receiving groove 4421 to meet the locking and unlocking needs; for example, the adjustment compensating part can be set to be threadedly connected to the groove wall of the receiving groove 4421, and the size of the connection position can be adjusted by adjusting the length of the adjustment compensating part screwed out into the receiving groove 4421.

[0056] It is understandable that the locking components are provided in three groups and are not arranged in a colinear manner. Figures 4 to 9 As shown, in this embodiment, by arranging the locking components in three groups with non-collinear distribution, the stability of the locking mechanism 400 on the grinding spindle assembly 200 is improved, avoiding the situation where only one group of locking components leads to excessive use intensity, mechanical fatigue, and potential processing instability.

[0057] It should be understood that if Figure 2 , Figure 7 , Figure 8 and Fig.10 As shown, the adjustment mechanism 300 includes a second drive assembly 310, a transmission assembly 320 and a sliding assembly 330. The second drive assembly 310 is arranged on the mounting frame, the transmission assembly 320 is connected to the output end of the second drive assembly 310, and the sliding assembly 330 is arranged on the grinding spindle assembly and connected to the transmission assembly 320. Specifically, the transmission assembly 320 includes a screw rod 321 and a nut 322, the nut 322 is threadedly connected to the screw rod 321, the sliding assembly 330 is connected between the nut 322 and the grinding spindle assembly 200, the screw rod 321 is connected to the output end of the second drive assembly 310, and can rotate under the drive of the second drive assembly 310, so that the nut 322 can drive the grinding spindle assembly 200 to rotate through the sliding assembly 330. The sliding assembly 330 includes a fixing member 331 and a first bearing 332. The fixing member 331 is fixed to the nut 322 and is provided with a slide groove 3311. The direction of the slide groove 3311, the rotation axis of the grinding spindle along the mounting frame 100 and the screw rod 321 are perpendicular to each other. The first bearing 332 is rotatably connected to the grinding spindle assembly 200 and can slide along the slide groove 3311. When in use, the second driving assembly 310 drives the fixing member 331 to move along the axial direction of the screw rod 321 through the transmission assembly 320, and can drive the first bearing 332 to slide through the slide groove 3311 of the fixing member 331, thereby realizing the rotation of the grinding spindle assembly 200, and then adjusting the swing angle of the grinding tool 220.

[0058] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
