Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a machine tool, machine tool processing components, and a grinding wheel for grinding workpieces. Background Technology

[0002] A grinding wheel is an abrasive tool made by bonding ordinary abrasive grains together with a binder to form a specific shape and strength. Most are circular, with a central through-hole for engagement with a rotating shaft. It generally consists of abrasive grains, a binder, and pores. When grinding workpieces with a grinding wheel, if the operator applies excessive force, causing the workpiece to slam against the wheel too hard, the wheel's structural strength is limited, making it susceptible to impact and breakage. This can result in flying fragments that damage surrounding objects and even injure the operator. Utility Model Content

Preferably, the grinding wheel body 1 and the clamping assembly 2 are respectively provided with multiple connecting holes, and a connector passes through the connecting holes to fix the grinding wheel body 1 and the clamping assembly 2 together. Preferably, the connector is a bolt connection assembly. The grinding wheel body 1 can adopt a structure already existing in the prior art, which will not be described in detail here.

[0030] The clamping assembly 2 includes a first clamping member 21, a second clamping member 22, a rotating member 23, and a moving member 24. The first clamping member 21 is mounted on one side of the grinding wheel body 1. The second clamping member 22 is mounted on the first clamping member 21. The rotating member 23 is mounted on the second clamping member 22. The moving member 24 is partially engaged in the first clamping member 21 and is located between the first clamping member 21 and the rotating member 23. When the rotating member 23 is rotated in a first direction, the lock on the second clamping member 22 is released, and the operator can push the moving member 24 to move the second clamping member 22 relative to the first clamping member 21. After the second clamping member 22 is adjusted to the desired position, when the rotating member 23 is rotated in a second direction opposite to the first direction, it acts on the moving member 24 to lock the second clamping member 22 onto the first clamping member 21.

[0031] The first clamping member 21 includes a first clamping member body 11 mounted on the grinding wheel body 1, and a plurality of engaging grooves 12 disposed on the side of the first clamping member body 11 facing the grinding wheel body 1. The first clamping member body 11 is generally annular. The engaging grooves 12 are trapezoidal grooves, and the dimension of the end of the engaging groove 12 away from the grinding wheel body 1 is larger than the dimension of the end of the engaging groove 12 adjacent to the grinding wheel body 1. Preferably, the engaging grooves 12 are recessed from the axial direction of the first clamping member body 11 and are arranged radially along the first clamping member body 11. The plurality of engaging grooves 12 are evenly distributed along the circumference of the first clamping member body 11. Preferably, the number of engaging grooves 12 is 6. The first clamping member body 11 has an installation opening 13 through the first clamping member body 11 at the position corresponding to the engaging groove 12. The first clamping member body 11 also has receiving grooves 14 located on both sides of the engaging grooves 12. Preferably, the receiving grooves 14 are generally fan-shaped.

[0032] The second clamping member 22 is at least partially engaged in the engagement groove 12. The second clamping member 22 includes a second clamping member body 221, a protrusion 222, and a connecting post 223. The second clamping member body 221 is engaged in the engagement groove 12. The protrusion 222 is disposed at one end of the second clamping member body 221. Preferably, in the axial direction of the first clamping member 21, the dimension of the protrusion 222 in that direction is smaller than the dimension of the second clamping member body 221 in that direction. Also preferably, the protrusion 222 is engaged in the receiving groove 14.

[0034] In use, the two clamping components 2 are installed on both sides of the grinding wheel body 1. As the grinding wheel body 1 wears down with continuous use, causing its circumference to decrease, the position of the second clamping component 22 relative to the first clamping component 21 can be adjusted. Specifically, when it is necessary to adjust the position of the second clamping component 22 of the clamping component 2, the rotating component 23 is rotated in the first direction to release the lock on the second clamping component 22, and the moving component 24 is pushed to move the second clamping component 22 relative to the first clamping component 21. After the second clamping component 22 is adjusted to the desired position, the rotating component 23 is rotated in the second direction opposite to the first direction. The rotating component 23 acts on the moving component 24 to lock the second clamping component 22 onto the first clamping component 21.
