The following describes the technical scheme provided by the embodiment of the application with reference to the accompanying drawings.

As shown in fig. 1 and 2, the present application provides a locking mechanism 100, where the locking mechanism 100 includes a first base 110 and a second base 120, and the locking mechanism 100 is mounted on a grinder 200, for locking the grinder 200 in a certain position. In the present embodiment, the polishing machine 200 has a polishing table (not shown) and a polishing arm 210, the polishing table can be used for carrying a workpiece, the polishing arm 210 is disposed above the polishing table at intervals, and the workpiece is polished by relative running friction between the polishing arm 210 and the workpiece.

The first base 110 is provided with a clamping member 111, and in this embodiment, the clamping member 111 is movably disposed on the first base 110, so that the clamping member 111 can move on the first base 110.

The second base 120 is disposed on the first base 110, and the second base 120 is rotatable relative to the first base 110, and the second base 120 is used for mounting the polishing arm 210, i.e. the polishing arm 210 can be mounted on the second base 120 by screwing, embedding, etc., and when the second base 120 rotates relative to the first base 110, the second base 120 can drive the polishing arm 210 to rotate relative to the first base 110. The second base 120 is provided with a clamping groove 121, and the clamping piece 111 can extend into or withdraw from the clamping groove 121 during the rotation process of the second base 120. In this embodiment, when maintenance operation is required to be performed on the polishing machine 200, the second base 120 drives the polishing arm 210 to rotate on the first base 110, and when the clamping groove 121 rotates to a position corresponding to the clamping piece 111, the clamping piece 111 can extend into the clamping groove 121 to lock the polishing arm 210 at a certain position, as shown in fig. 1, the polishing arm 210 is locked at a position extending to the outside of the polishing table, so that the polishing arm 210 is prevented from interfering with the maintenance operation of the polishing machine 200, the maintenance operation of the polishing machine 200 is facilitated for an operator, and the dead angle position on the polishing table can be cleaned, so that the polishing quality of the workpiece on the polishing table is improved. After the maintenance operation of the grinder 200 is completed, the clamping member 111 is withdrawn from the clamping groove 121 to unlock the grinding arm 210, and as shown in fig. 3, the grinding arm 210 can be rotated again above the grinding table to continue the grinding and polishing process for the workpiece carried on the grinding table.

In order to complete the insertion or withdrawal of the clamping member 111 relative to the clamping groove 121, in one embodiment, as shown in fig. 1 and 2, the clamping member 111 includes an elastic member 112 and a clamping pin 113. The elastic member 112 is disposed on the first base 110, so as to fix the elastic member 112 on the first base 110, the locking pin 113 is disposed at an end of the elastic member 112 by welding, abutting, etc., and the locking pin 113 is close to the second base 120. The deformation direction of the elastic member 112 is consistent with the movement direction of the bayonet 113, and the elastic member 112 is used for driving the bayonet 113 to move towards the direction approaching the bayonet slot 121. Specifically, when the clamping groove 121 rotates to a position corresponding to the clamping piece 111, under the elastic action of the elastic piece 112, the elastic piece 112 stretches and pushes the clamping pin 113 to move towards a direction close to the clamping groove 121, and the clamping pin 113 stretches into the clamping groove 121 to lock the grinding arm 210, so that an operator can conveniently maintain the grinding machine 200. After the maintenance operation of the polishing machine 200 is completed, the operator can apply a force on the locking pin 113 or the elastic member 112, the elastic member 112 compresses and drives the locking pin 113 to move away from the locking groove 121, and the locking pin 113 is made to exit from the locking groove 121 to unlock the polishing arm 210, so that the polishing arm 210 can be rotated above the polishing table again to continue the polishing process for the workpiece carried on the polishing table.

In this embodiment, the elastic member 112 is a return spring, and when the elastic member 112 receives an acting force, the elastic member 112 can be elastically deformed to drive the latch 113 to move toward a direction approaching or separating from the latch slot 121. Of course, in other embodiments, the type of the elastic member 112 is not limited to the above-provided return spring, but may be an elastic sheet, a flexible sheet, or other elastically deformable material. The specific type of elastic member 112 is not limited in this application.

In order to provide the clamping member 111 on the first base 110, in an embodiment, as shown in fig. 1 and 2, the first base 110 is provided with a receiving groove 114, and the receiving groove 114 is opened at an end surface of the first base 110 close to the second base 120, in other words, the receiving groove 114 is opened at an end surface of the first base 110 facing the second base 120, and the receiving groove 114 extends toward the inside of the first base 110. In this embodiment, the accommodating groove 114 is a cylindrical groove, and the shape of the sidewall of the accommodating groove 114 is adapted to the outer surface of the bayonet 113, and a space is provided between the two. The elastic member 112 is disposed in the accommodating groove 114, for example, the elastic member 112 may be disposed in the accommodating groove 114 by welding, embedding, etc. to realize the arrangement of the elastic member 112 on the first base 110, and the locking pin 113 is at least partially movably disposed in the accommodating groove 114, and when the elastic member 112 is elastically deformed by the acting force, the elastic member 112 may drive the locking pin 113 to extend into or withdraw from the locking groove 121. It should be noted that, in the present embodiment, the accommodating groove 114 may be integrally formed with the first base 110 by extrusion, casting, etc., so as to simplify the forming process of the accommodating groove 114 on the first base 110 and save the cost of forming the accommodating groove 114 on the first base 110.

As shown in fig. 2 and fig. 4, in some embodiments, the accommodating groove 114 is only opened on the end surface of the first base 110 facing the second base 120, and at this time, the side wall of the accommodating groove 114 is of a closed structure, so that on one hand, the bending defect of the elastic member 112 during the elastic deformation process can be prevented, and on the other hand, dust, water stain, etc. during the maintenance operation of the grinder 200 are prevented from splashing into the accommodating groove 114, which affects the operation of the bayonet 113, i.e. prevents the movement of the bayonet 113 from being blocked, and further improves the smoothness of the movement of the bayonet 113.

In one embodiment, as shown in fig. 1 and 2, the bayonet 113 has a guiding post (not shown) at an end portion extending into the accommodating groove 114, that is, the bayonet 113 has a guiding post at an end portion away from the second base 120. In this embodiment, the guide post can be integrally formed with the bayonet 113 by casting, extrusion, etc., so as to simplify the forming process of arranging the guide post on the bayonet 113 and save the manufacturing cost of arranging the guide post on the bayonet 113. The end of the elastic member 112 away from the bayonet 113 is connected to the bottom wall of the accommodating groove 114 by welding, abutting, or the like, and the elastic member 112 is partially wound around the guide post, and a gap is formed between the guide post and the bottom wall of the accommodating groove 114, such as in the present embodiment, when the elastic member 112 is in a natural state, i.e. the elastic member 112 is not stressed, the length of the elastic member 112 in the deformation direction is greater than the length of the guide post in the extending direction. Through winding the elastic piece 112 on the guide post, when the elastic piece 112 moves in the deformation direction, the guide post can guide the movement track of the elastic piece 112, so that the elastic piece 112 can drive the clamping pin 113 to accurately extend into or withdraw from the clamping groove 121, and the matching reliability of the clamping piece 111 and the clamping groove 121 is improved.

Further, as shown in fig. 1 and 2, the side of the bayonet 113 near the second base 120 has a circular arc end. If the end surface of the bayonet 113 near the side of the second base 120 is a plane, when the relative position of the bayonet 113 and the engagement slot 121 deviates, the bayonet 113 is easily abutted against the opening of the engagement slot 121 during the process of extending into the engagement slot 121, so that the bayonet 113 cannot extend into the engagement slot 121. In the present embodiment, an arc surface is disposed at the end of the bayonet 113 near the second base 120, and when the relative position of the bayonet 113 and the engagement slot 121 deviates, the arc surface can guide and correct the position of the bayonet 113 extending into the engagement slot 121, so that the bayonet 113 can smoothly enter into the engagement slot 121 to lock the grinding arm 210.

In other embodiments, the end surface of the bayonet 113 near the side of the second base 120 is not limited to the arc surface provided above, and may be a tapered surface or other shaped surface. The specific shape of the end surface of the bayonet 113 near the side of the second base 120 is not limited in this application, and may be specifically set according to the user's requirement.

In order to enable the clamping member 111 to withdraw from the clamping groove 121, in one embodiment, as shown in fig. 1 and 2, the clamping pin 113 has a poking portion 115. In one embodiment, the poking portion 115 is a poking groove formed on the bayonet 113, the poking groove is opened towards the outer side of the bayonet 113, and when the maintenance operation of the polishing machine 200 is completed, an operator can poke the poking groove with a finger, so that the operator can apply a force on the bayonet 113 conveniently, the elastic member 112 is compressed, and the bayonet 113 is withdrawn from the bayonet 121 to unlock the polishing arm 210. Since the operator is usually familiar with carrying an allen wrench, the striking portion 115 is configured as a striking groove, and the operator can apply a force on the bayonet 113 by means of the wrench.

In another embodiment, the striking portion 115 is a texture provided on the surface of the detent 113. The texture can increase the roughness of the surface of the bayonet 113, and an operator can apply a force on the bayonet 113 by applying a finger to the texture portion, so that the elastic member 112 is compressed, and the bayonet 113 is withdrawn from the clamping groove 121 to unlock the grinding arm 210.

In order to further improve the reliability of the engagement between the engaging member 111 and the engaging groove 121, in an embodiment, as shown in fig. 1 and 2, the engaging groove 121 has an open end 122 at a side near the first base 110, and the open end 122 is gradually expanded toward the first base 110, for example, two guiding surfaces are disposed at a side of the engaging groove 121 near the first base 110, and the guiding surfaces extend toward the outer side of the engaging groove 121. The opening end 122 of the clamping groove 121 is arranged to be gradually expanded, so that the opening section of the clamping groove 121 can be increased, the clamping pin 113 can more smoothly extend into the clamping groove 121 to realize self-locking operation on the grinding arm 210, the phenomenon that the clamping pin 113 cannot extend into the clamping groove 121 when the relative position of the clamping pin 113 and the clamping groove 121 is deviated is avoided, and the matching reliability of the clamping piece 111 and the clamping groove 121 is further improved.

In an embodiment, as shown in fig. 1 and fig. 2, two clamping grooves 121 are provided, and the two clamping grooves 121 are disposed adjacent to each other along the circumferential direction of the second base 120. Due to the installation process error, the relative position of the clamping pin 113 and the clamping groove 121 is deviated, and by arranging two adjacent clamping grooves 121 on the second base 120, the self-locking operation can be performed on the grinding arm 210 only when the clamping pin 113 extends into any one of the two clamping grooves 121, so as to compensate the deviation of the alignment caused by the installation process error.

In another embodiment, as shown in fig. 1 and 2, the plurality of the clamping grooves 121 are plural, and the plurality of clamping grooves 121 are disposed at intervals along the circumferential direction of the second base 120. A plurality of clamping grooves 121 are formed in the circumferential direction of the second base 120 at intervals, when the clamping pieces 111 are clamped in different clamping grooves 121, the grinding arms 210 can be adjusted to different locking positions, different position requirements of operators on the locking positions of the grinding arms 210 are met, and the operators can conveniently maintain the grinding machine 200 at different positions. If the number of the clamping grooves 121 is three, the angle between two adjacent clamping grooves 121 is 120 °, when the clamping member 111 is clamped in the first clamping groove 121, the polishing arm 210 can be locked at the first position, when the clamping member 111 is clamped in the second clamping groove 121, the polishing arm 210 can be locked at the second position, and when the clamping member 111 is clamped in the third clamping groove 121, the polishing arm 210 can be locked at the third position. Of course, the number of the clamping grooves 121 may be four, five or other numbers, and the setting positions of the plurality of clamping grooves 121 on the second base 120 may be adaptively set according to the setting manner provided above, which is not described herein.

The grinding arms 210 are arranged above the grinding table at intervals, load the workpiece on the grinding table, and grind and polish the workpiece by relative running friction between the grinding arms 210 and the workpiece. The locking mechanism 100 is used for mounting the grinding arm 210, for example, in this embodiment, the grinding arm 210 may be mounted on the second base 120 by screwing, embedding, etc., and when the second base 120 rotates relative to the first base 110, the second base 120 may drive the grinding arm 210 to rotate relative to the first base 110.

When the grinding machine 200 needs to be maintained, the second base 120 drives the grinding arm 210 to rotate on the first base 110, and when the clamping groove 121 rotates to a position corresponding to the clamping piece 111, the clamping piece 111 can extend into the clamping groove 121 to lock the grinding arm 210 at a certain position, for example, the grinding arm 210 is locked at a position extending to the outer side of the grinding table, so that the grinding arm 210 is prevented from interfering with the maintenance operation of the grinding machine 200, the operator can conveniently maintain the grinding machine 200, the dead angle position on the grinding table can be cleaned, and the grinding and polishing quality of the workpiece on the grinding table can be improved. After the maintenance operation of the grinder 200 is completed, the clamping member 111 is withdrawn from the clamping groove 121 to unlock the grinding arm 210, and the grinding arm 210 can be rotated again above the grinding table to continue the grinding and polishing process for the workpiece carried on the grinding table.
