The dressing process is observed through a perspective lens to ensure dressing accuracy. It is suitable for surface grinders and universal tool grinders, and can precisely dress small arcs and angles to achieve very high precision. The contact between the diamond tip and the surface to be dressed on the grinding wheel is observed through a lens to ensure the dressing effect.

[0003] When using the existing device for dressing CBN grinding wheels on ordinary grinding machines, the device is used to dress grinding wheels of various angles, arcs, and straight lines. However, when the existing device is left idle for too long, dust from the air will accumulate on the surface of the lens, making it difficult to clean and affecting normal use. Utility Model Content

[0004] The purpose of this invention is to provide a device for dressing CBN grinding wheels on a conventional grinding machine, in order to solve the problem mentioned in the background art that when the existing device is left idle for a long time, dust from the air will be absorbed on the surface of the lens, making the lens surface difficult to clean and affecting normal use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for dressing CBN grinding wheels on a conventional grinding machine, comprising:

[0006] The device body includes a support base, a viewing mirror is provided inside the support base, a support plate is connected to one end of the support base, and a pen tip is inserted inside one end of the support plate.

[0007] The top of the support plate is connected to a protective mechanism, which includes a fixed frame. A threaded rod is inserted inside the fixed frame. One end of the threaded rod is movably connected to a bearing. One end of the bearing is connected to a hinge frame. One end of the hinge frame is hinged to a protective sleeve plate.

[0008] Preferably, the surface of the fixing frame is provided with a threaded hole, and the threaded rod is rotatably connected to the inside of the threaded hole of the fixing frame.

[0009] Preferably, the threaded rod and the hinge frame are movably connected by bearings, the surface of the protective sleeve is made of elastic material, the surface of the support plate is provided with a limiting groove, and the protective sleeve can be fitted into the limiting groove provided in the support plate.

[0010] Preferably, a groove is provided on one end surface of the hinge frame, and the bottom end of the protective sleeve is inserted into the groove of the hinge frame and hinged to the hinge frame.

[0011] Preferably, the back surface of the protective sleeve is connected to a limiting structure, the limiting structure including a fixed base, a slider connected to one side of the fixed base, a support spring connected to the bottom end of the fixed base, a magnetic sleeve connected to the bottom end of the support spring, and a magnet adsorbed on the bottom surface of the magnetic sleeve.

[0012] Preferably, the bottom end of the support spring is connected to one side of the inner surface of the magnetic sleeve, and the fixed base and the magnetic sleeve are elastically connected by the support spring.

[0013] Preferably, the magnetic sleeve has a movable groove on one side, and one end of the slider is inserted into the movable groove of the magnetic sleeve and slidably connected to the magnetic sleeve. The magnet plate is connected to the top surface of the fixed frame, and the magnetic sleeve and the magnet plate are magnetically attracted to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the threaded rod, it moves along the thread along the thread in the threaded hole of the fixed frame, and the threaded rod drives the hinge frame and the protective sleeve plate to move simultaneously. The bearing ensures that the rotation of the threaded rod does not affect the angle of the hinge frame. Then, rotate the protective sleeve plate so that it abuts against the surface of the limiting groove of the iris. Then, rotate the threaded rod in the opposite direction so that the surface of the protective sleeve plate is fitted into the limiting groove of the iris. This protects the surface of the iris from dust and prevents damage to the surface of the iris caused by scratches. It also prevents the surface of the iris from absorbing dust from the air, making the surface of the iris difficult to clean and affecting normal use.

[0016] 2. By rotating the protective sleeve plate, the support spring connected to the bottom of the fixed base supports the magnetic sleeve to move. The support spring provides elastic buffering between the fixed base and the magnetic sleeve, allowing the magnetic sleeve to move and limit the slider using the movable groove. This allows the bottom of the magnetic sleeve to be inserted into the magnet plate. The magnetic force between the magnetic sleeve and the magnet plate attracts them, thereby limiting the position of the protective sleeve plate and achieving the function of limiting the angle of the protective sleeve plate.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] An apparatus for dressing CBN grinding wheels on a conventional grinding machine, comprising:

[0026] The device body 1 includes a support base 11, a viewing mirror 12 is provided inside the support base 11, a support plate 13 is connected to one end of the support base 11, and a pen tip 14 is inserted into one end of the support plate 13. The internal material of the support base 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, therefore, no further details are made.

[0027] The top of the support plate 13 is connected to a protective mechanism 2. The protective mechanism 2 includes a fixed frame 21. A threaded rod 22 is inserted inside the fixed frame 21. One end of the threaded rod 22 is movably connected to a bearing 23. One end of the bearing 23 is connected to a hinge frame 24. One end of the hinge frame 24 is hinged to a protective sleeve plate 25.

[0028] Furthermore, the surface of the fixing frame 21 is provided with a threaded hole, and the threaded rod 22 is rotatably connected to the inside of the threaded hole of the fixing frame 21, so as to limit the threaded rod 22 through the threaded hole of the fixing frame 21.

[0029] Furthermore, the threaded rod 22 and the hinge frame 24 are movably connected by the bearing 23. The surface of the protective sleeve 25 is made of elastic material, and the surface of the support plate 13 is provided with a limiting groove. The protective sleeve 25 can be fitted into the limiting groove provided in the support plate 13, so that the protective sleeve 25 can be limited by the limiting groove provided in the support plate 13.

[0030] Furthermore, a groove is provided on one end surface of the hinge frame 24, and the bottom end of the protective sleeve 25 is inserted into the groove provided in the hinge frame 24 and hinged to the hinge frame 24, so as to position the bottom end of the protective sleeve 25 through the groove provided in the hinge frame 24.

[0031] Furthermore, a limiting structure 3 is connected to the back surface of the protective sleeve 25. The limiting structure 3 includes a fixed base 31, a slider 32 connected to one side of the fixed base 31, a support spring 33 connected to the bottom end of the fixed base 31, a magnetic sleeve 34 connected to the bottom end of the support spring 33, and a magnet 35 adsorbed on the bottom surface of the magnetic sleeve 34, so as to limit the angle of the protective sleeve 25 by the magnetic sleeve 34 and the magnet 35.

[0032] Furthermore, the bottom end of the support spring 33 is connected to one side of the inner surface of the magnetic sleeve 34, and the fixed base 31 and the magnetic sleeve 34 are elastically connected by the support spring 33, so as to achieve flexible buffering between the fixed base 31 and the magnetic sleeve 34 through the support spring 33.

[0033] Furthermore, a movable groove is provided on one side of the magnetic sleeve 34, and one end of the slider 32 is inserted into the movable groove of the magnetic sleeve 34 and slidably connected to the magnetic sleeve 34. The magnet plate 35 is connected to the top surface of the fixed frame 21. The magnetic sleeve 34 and the magnet plate 35 are magnetically attracted and connected, so that the protective sleeve plate 25 is limited by the mutual attraction between the magnetic sleeve 34 and the magnet plate 35.

[0034] Working principle: When protecting the device used for dressing CBN grinding wheels on a conventional grinding machine, the threaded rod 22 is rotated to move along the thread in the threaded hole of the fixed frame 21. The threaded rod 22 drives the hinge frame 24 and the protective sleeve 25 to move simultaneously. The bearing 23 ensures that the rotation of the threaded rod 22 does not affect the angle of the hinge frame 24. Then, the protective sleeve 25 is rotated to abut against the surface of the limiting groove of the perspective mirror 12. Then, the threaded rod 22 is rotated in the opposite direction to make the surface of the protective sleeve 25 fit into the limiting groove of the perspective mirror 12, thus protecting the surface of the perspective mirror 12 from dust and preventing damage to the surface of the perspective mirror 12 due to scratches.

[0035] When limiting the device used for dressing CBN grinding wheels on a conventional grinding machine, the support spring 33 connected to the bottom of the fixed base 31 is connected to the protective sleeve 25 by rotating the protective sleeve 25, which supports the magnetic sleeve 34 to move. The support spring 33 provides elastic buffering between the fixed base 31 and the magnetic sleeve 34, allowing the magnetic sleeve 34 to limit the movement of the slider 32 through the movable groove. This allows the bottom of the magnetic sleeve 34 to be inserted into the magnet plate 35. The magnetic force between the magnetic sleeve 34 and the magnet plate 35 attracts them, thereby limiting the protective sleeve 25 and achieving the angular limiting function of the protective sleeve 25.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
