Description

Technical Field

[0001] The utility model relates to a universal grinding wheel clamp for a grinding machine and a grinding wheel dresser. Background Art

[0002] When using a grinder to process parts, the grinding wheel needs to be clamped on the mounting shaft of the grinder. After the grinding wheel has been used for a period of time, it needs to be removed from the mounting shaft of the grinder and clamped on the mounting shaft of the grinding wheel dresser for grinding. After grinding, the grinding wheel is re-clamped on the mounting shaft of the grinder and continued to be used. At present, since the grinding wheel is clamped on the mounting shaft of the grinder and on the mounting shaft of the grinding wheel dresser respectively using two different fixtures, when the grinding wheel needs to be switched between using the grinder and dressing on the grinding wheel dresser, the grinding wheel needs to be removed from the previous fixture and installed on the latter fixture. This process not only consumes time, but also has certain installation positioning errors. Utility Model Content

[0003] The purpose of the utility model is to provide a universal grinding wheel clamp for a grinder and a grinding wheel dresser, which can be switched between the mounting axis of the grinder and the mounting axis of the grinding wheel dresser when the grinding wheel is clamped, so as to solve the technical problem that the grinding wheel needs to be removed from the previous clamp and installed on the latter clamp when switching between using the grinding wheel on the grinder and dressing on the grinding wheel dresser.

[0004] A universal grinding wheel fixture for a grinding machine and a grinding wheel dresser, comprising: a center sleeve, one end of the center sleeve being a screw end and the other end being a shoulder end with a shoulder, the center sleeve having a stepped hole coaxially arranged with the center sleeve, the stepped hole being composed of a through hole section and a countersunk hole section arranged in the shoulder end, the countersunk hole section being a threaded hole; a locking nut, the internal thread of the locking nut being matched with the external thread of the screw end, the locking nut being used for axially locking the grinding wheel which is sleeved on the center sleeve and axially confined between the shoulder and the locking nut; wherein, when the locking nut is installed, the screw end can still be threadably connected to the countersunk hole section of the previous center sleeve, the threaded hole can be threadably connected to the screw end of the next center sleeve, and the through hole section can be respectively matched with the mounting shaft of the grinding machine and the mounting shaft of the grinding wheel dresser.

[0005] It further includes: a first replaceable washer, which is sleeved on the center sleeve and axially pressed between the boss and the grinding wheel; and a second replaceable washer, which is sleeved on the center sleeve and axially pressed between the locking nut and the grinding wheel.

[0006] Optionally, the locking nut is formed by the shoulder end of the previous central sleeve. Optionally, a first rotation-carrying structure is provided on the cylindrical surface of the shoulder. Optionally, the first rotation-carrying structure includes a first rotation-carrying plane.

[0007] Since the through hole section can be respectively adapted to the mounting axis of the grinder and the mounting axis of the grinding wheel dresser, the above-mentioned grinding wheel clamp can be mounted on the mounting axis of the grinder or the mounting axis of the grinding wheel dresser, so that the installation can be switched between the mounting axis of the grinder and the mounting axis of the grinding wheel dresser while clamping the grinding wheel, thereby improving work efficiency and reducing installation positioning errors.

[0008] In addition, since the screw end of the above-mentioned grinding wheel clamp can still be threadedly adapted and connected with the countersunk hole section of the previous center sleeve when the locking nut is installed, and the threaded hole of the grinding wheel clamp can be threadedly adapted and connected with the screw end of the rear center sleeve, one grinding wheel clamp can be connected in series with other grinding wheel clamps, so that more than two grinding wheels can be installed on the mounting shaft of the grinding wheel dresser at the same time, and more than two grinding wheels can be clamped and ground at one time, greatly improving the grinding efficiency of the grinding wheel.

[0009] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Additional aspects and advantages provided by the present invention will be partially given in the following description, partially become apparent from the following description, or be understood through practice.
