Meanwhile, the height of the second rack 224 limits the angle of up and down rotation of the ring 223, and there are two ways in which the height of the second rack 224 limits the angle of up and down rotation of the ring 223: 1. when the width of the first rack 212 is smaller, the tooth shape and the tooth space on the first rack 212 can adapt to the tooth shape and the tooth space at different positions on the second rack 224, the up-down rotation of the second rack 224 is not interfered by the first rack 212, and when the highest end of the second rack 224 is abutted to the bottom of the limiting cavity 213, the circular ring 223 is still; 2. when the width dimension of the first rack 212 is larger, the tooth shape of the first rack 212 is adaptively set, so that the second rack 224 is clamped on the first rack 212 after rotating for a certain angle, the up-down rotation of the second rack 224 is influenced by the interference of the first rack 212, and when the second rack 224 rotates and is abutted on the first rack 212, the highest end of the second rack 224 is extruded with the first rack 212, and the circular ring 223 is stationary. Therefore, the width, the tooth shape and the tooth spacing of the first rack 212 can be adaptively set according to practical requirements. The inner side of the circular ring 223 is provided with a spherical cambered surface corresponding to the spherical structure 211, so that the circular ring 223 rotates more stably.
Further, the second rack 224 is provided with a bevel structure, and when the second rack 224 abuts against the first rack 212 and is kept still, the horizontal portion 221 and the workbench 3 are both in horizontal positions; when the inclined surface structure is parallel to the upper and lower ends of the base 21, the second rack 224 is separated from contact with the first rack 212, and the ring 223 can horizontally rotate relative to the base 21. The relative fixing and rotation of the circular ring 223 are realized by utilizing different positions of the first rack 212 and the second rack 224. When the workpiece is ground, the workpiece is placed on the workbench 3, the self weight of the workpiece can strengthen the fixation of the circular ring 223, and vibration is reduced.
Referring to fig. 2 to 9, further, the grinding table of the grinder further includes a locking assembly 4, wherein the locking assembly 4 is used for fixing the bracket 22. When the ring 223 is rotated by a proper angle and the workbench 3 is rotated to a designated position, the support 22 is fixed by the locking assembly 4, so that the workbench 3 is more reliably used, and vibration caused by rotation of the grinding wheel can be reduced.
Further, the locking assembly 4 includes: the abutting block 41, the abutting block 41 is slidably connected with the bracket 22, the abutting block 41 can abut against the spherical structure 211, the abutting block 41 is slidably connected with the horizontal portion 221 of the bracket 22, the inside of the horizontal portion 221 and the vertical portion 222 of the bracket 22 is hollow, when the abutting block 41 moves to the tail end of the horizontal portion 221, the abutting block abuts against the surface of the spherical structure 211, and the relative fixation of the bracket 22 is realized by the friction force between the abutting block 41 and the spherical structure 211. The end surface of the abutment block 41 may be adaptively set to an arc surface, which is a conventional structure to increase the contact area with the spherical structure 211 and improve the fixing stability, and is not shown in fig. 8.
Further, the locking assembly 4 further includes: the abutment post 42, abutment post 42 sliding connection support 22, the direction of movement of abutment piece 41 with the direction of movement of abutment post 42 is perpendicular, the outside in spacing chamber 213 can be abutted to abutment post 42, realizes the fixed of ring 223 vertical direction, has reduced the vibrations in the workstation 3 use. If the second rack 224 at the position of the abutment post 42 is located below the circular ring 223, the abutment post 42 can abut the outside of the upper side limiting cavity 213, if the second rack 224 at the position of the abutment post 42 is located above the circular ring 223, the abutment post 42 can abut the outside of the lower side limiting cavity 213, namely: the overhanging ends of the abutting columns 42 are symmetrically arranged with the second racks 224 where the overhanging ends are located, so that the abutting of the second racks 224 and the abutting columns 42 to the base 21 in the upper and lower directions is ensured, and the fixing stability of the support 22 is ensured.
Referring to fig. 8 and 9, further, the abutment post 42 is provided with a guide protrusion 421, the abutment block 41 is provided with a guide slot 411 corresponding to the guide protrusion 421, the guide protrusion 421 is slidably connected to the guide slot 411, and when the abutment block 41 moves toward the spherical structure 211, the guide slot 411 ejects the guide protrusion 421 outwards; when the abutting block 41 moves away from the spherical structure 211, no force is generated between the guide protrusion 421 and the guide slot 411. The guide protrusion 421 on the abutting column 42 is inclined at a certain angle with the axis of the abutting column 42, the guide slot 411 corresponds to the guide protrusion 421, when the guide slot 411 moves inwards, the guide protrusion 421 is abutted outwards, and when the abutting block 41 abuts against the spherical structure 211, the abutting block 41 abuts against the outer side of the limiting cavity 213, so that double fixing is realized. When the abutment block 41 moves backward, the abutment column 42 loses the supporting force of the abutment block 41 and is in a free state, and when the support 22 moves up and down in a rotating manner, the base 21 can press the abutment column 42 into the support 22, so that the rotation of the support 22 is prevented from being affected.
Further, a plurality of balls 422 are arranged on the contact surface between the guide protrusions 421 and the guide slots 411, the balls 422 are rotationally connected with the guide protrusions 421, and the balls 422 change the dynamic friction between the guide protrusions 421 and the guide slots 411 into rolling friction, so that the friction force is reduced, and the movement sensitivity of the abutting columns 42 is improved.
Further, the elastic layers are fixedly connected to the ends of the abutting block 41 and the abutting column 42, so that friction force between the abutting block 41, the abutting column 42 and the base 21 is increased, and vibration is reduced. The elastic layer may be fixed by adhesion, screwing, or the like. Because the abutting block 41 and the abutting column 42 need to be abutted against the base 21 at the same time, the size requirements of the abutting block 41 and the abutting column 42 are strict, and the addition of the elastic layer can reduce the processing difficulty and the cost. The elastic layer can be made of rubber or polyurethane material, and has abrasion resistance and long service life.

When the wrench 46 rotates, the third link 45 is driven to move up and down, and the third link 45 drives the first link 43 to rotate, thereby realizing the movement of the abutment block 41. The wrench 46 protrudes from the outer wall of the bracket 22 to facilitate manual operation. When the first link 43 and the second link 44 are positioned at the same straight line position, the whole third link 45 and the rotation hinge point of the wrench 46 are positioned at the same straight line position, namely: the third link 45 is at the rotation dead point position of the first link 43 and the second link 44, and ensures reliable abutment of the abutment block 41 on the spherical structure 211. A torsion spring is disposed between the wrench 46 and the bracket 22, so that the wrench 46 normally presses the third link 45 downward to make the abutment block 41 abut against the spherical structure 211.
