As shown in fig. 6 and 7, the limiting assembly further includes a second limiting mechanism 34, wherein the second limiting mechanism 34 penetrates through the limiting block 31 along the length direction of the groove 21 and is connected with the limiting block 31 in a threaded manner, so as to adjust the length of the second limiting mechanism 34 penetrating through the limiting block 31 to be in abutting contact with the finishing stone 1. Second stop gear 34 is connected with stopper 31 with the threaded connection, is convenient for change second stop gear 34 and pass stopper 31's length according to the length of actually repairing stone 1, has increased the embodiment of the utility model provides a grinding wheel dresser's application scope.

In an alternative mode, the second position-limiting mechanism 34 includes a threaded rod 341, a handle 342, and a stop plate 343, and the threaded rod 341 passes through the position-limiting block 31 and is in threaded connection with the position-limiting block 31. A handle 342 is arranged tightly at the end of the threaded rod 341 remote from the finishing stone 1. The baffle 343 is disposed tightly at an end of the threaded rod 341 near the finishing stone 1. The handle 342 is provided to facilitate the operation of the operator to adjust the length of the threaded rod 341 that passes through the stopper 31. The baffle 343 increases the force-bearing area between the second limiting mechanism 34 and the dressing stone 1, reduces the pressure applied to the dressing stone 1, and avoids damaging the dressing stone 1. After the position of the limiting block 31 is limited in the groove 21 under the action of the first limiting mechanism 33 and the limiting column 32, an operator can rotate the handle 342 to rotate the threaded rod 341, so as to adjust the length of the threaded rod 341 penetrating through the limiting block 31, and finally the blocking plate 343 is blocked at one end of the finishing stone 1.

The following description is given by way of example of one possible implementation of the grinding wheel dresser according to the present invention, and it is to be understood that the following description is only for the purpose of understanding and is not intended to be limiting.

Referring to fig. 1 to 9, after the operator places the dresser body 2 on the table, the operator holds the dressing stone 1 by hand and slides the dressing stone 1 along the groove 21 from the through end of the groove 21 until the end of the dressing stone 1 comes into contact with the closed end of the groove 21. Next, the stopper assembly is installed, and a force is applied to the upper end of the stopper plate 331, so that the two stopper plates 331 move toward each other, the elastic member 333 is compressed, and the distance between the two stopper plates 331 is reduced. Because the connecting rod 332 is hinged to the limiting plate 331 and the limiting column 32, the end of the connecting rod 332 connected to the limiting column 32 swings upward around the end of the connecting rod 332 connected to the limiting plate 331, so as to drive the limiting column 32 to ascend, and the limiting column 32 moves into the limiting block 31. At this time, the stopper member is assembled into the groove 21 from the penetrating end of the groove 21. Then, the operator can loosen the limiting plates 331, and under the elastic action of the elastic element 333, the two limiting plates 331 are tightly attached to the inner walls of the grooves 21. The operator pushes the stopper 31 to slide the stopper 31 along the groove 21 in the groove 21. When the two limit plates 331 slide to the limit grooves 22, because the width of the limit grooves 22 is greater than the groove 21, and the limit grooves 22 correspond to the limit plates 331, under the elastic action of the elastic element 333, the side surfaces of the limit plates 331 are in limit contact with the limit grooves 22, and the distance between the two limit plates 331 is increased, so that the end, connected with the limit post 32, of the connecting rod 332 swings downwards around the end, connected with the limit plate 331, of the connecting rod 332, the limit post 32 is driven to descend, the limit post 32 extends out of the limit block 31, further, the bottom end of the limit post 32 is embedded into the limit hole 23, and the position of the limit component in the groove 21 is limited. The handle 342 is held by hand, the threaded rod 341 is rotated, so that the threaded rod 341 drives the baffle 343 to move towards the direction close to the dressing stone 1 until the baffle 343 abuts against one end of the dressing stone 1, which is close to the through groove 21, and the position of the dressing stone 1 on the dresser body 2 is fixed. When the dressing stone 1 needs to be taken down from the dresser main body 2, an operator applies an acting force to the upper end of the limiting plate 331, so that the limiting plate 331 moves towards the direction close to the limiting block 31 along the length direction of the guide rod 334, the elastic element 333 is further compressed, the distance between the two limiting plates 331 is reduced, one end of the connecting rod 332 connected with the limiting column 32 swings upwards around the end of the connecting rod 332 connected with the limiting plate 331, and the limiting column 32 is driven to ascend to the limiting column 32 and move into the limiting block 31. At this time, the limiting assembly can be moved to slide along the groove 21 until the limiting assembly slides out of the groove 21, and at this time, the dressing stone 1 can be taken down from the dresser main body 2.
