Description

Technical Field

[0001] This utility model belongs to the field of polishing technology, specifically relating to a polishing wheel fixing bracket for a polishing machine. Background Technology

[0002] The main function of the polishing wheel holder in a polishing machine is to ensure that the polishing wheel can be securely installed, preventing it from loosening or detaching during high-speed rotation, thus ensuring operational safety and processing stability. As an indispensable key component of a polishing machine, the polishing wheel holder not only needs to provide a secure fixation but also needs to support quick replacement of polishing wheels of different sizes and types to meet diverse processing needs.

[0003] In the existing technology, the most common way to install polishing wheels is by using the center hole fixing method. The polishing wheel has a hole in the center, through which the polishing wheel is fitted onto the shaft of the polishing machine and fixed with a nut or other fasteners. However, this method requires removing the nut and the entire wheel every time the polishing wheel is replaced. The process is relatively cumbersome and time-consuming. It is inconvenient when it is necessary to frequently change polishing wheels of different sizes, which reduces the ease of operation and leads to a decrease in work efficiency.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a polishing wheel fixing bracket for a polishing machine, comprising:

[0026] Support platform 100;

[0027] The drive mechanism 200 includes a cylinder 201 adapted to be installed on the outer surface of the support platform 100, a rotating column 202 sleeved on the outer surface of the cylinder 201, a fixed sleeve 203 fixedly installed on the outer end face of the cylinder 201, an inner support assembly 204 disposed on the outer surface of the fixed sleeve 203, a polishing wheel 205 sleeved on the outer surface of the inner support assembly 204, and a rotating assembly 206 used in conjunction with the inner support assembly 204.

[0028] Specifically, the inner surface of the rotating column 202 is rotatably connected to the outer surface of the cylinder 201, and a bearing sleeve for rotation is installed at the connection between the rotating column 202 and the cylinder 201.

[0029] The rotating column 202 and the cylinder 201 are connected by a bearing sleeve, which can ensure the smoothness and accuracy of the rotation process and reduce vibration and eccentricity problems.

[0030] Furthermore, the inner support assembly 204 includes several first guide rods 204a rotatably connected to the inner surface of the fixed sleeve 203, and several limiting blocks 204b fixedly installed on the outer surface of the rotating column 202.

[0031] Furthermore, the inner support assembly 204 also includes a second guide rod 204c rotatably connected to the inner surface of the limiting block 204b, and an arc-shaped clamping plate 204d rotatably connected to the other end of the first guide rod 204a and the second guide rod 204c.

[0032] The first guide rod 204a and the second guide rod 204c ensure that the arc-shaped clamping plate 204d can stably fix the inner diameter of the polishing wheel 205. The rotational connection between the first guide rod 204a and the second guide rod 204c and the fixing sleeve 203 and the limiting block 204b makes the clamping force distribution more uniform and reduces polishing quality problems caused by unstable clamping.

[0033] Furthermore, a bearing sleeve for rotation is installed at the connection between the first guide rod 204a and the fixed sleeve 203, a bearing sleeve for rotation is installed at the connection between the first guide rod 204a and the arc-shaped clamping plate 204d, a bearing sleeve for rotation is installed at the connection between the second guide rod 204c and the limiting block 204b, a bearing sleeve for rotation is installed at the connection between the limiting block 204b and the arc-shaped clamping plate 204d, and the outer surface of the arc-shaped clamping plate 204d is in contact with the inner surface of the polishing wheel 205.

[0034] Preferably, the rotating assembly 206 includes a motor 206a adapted to be mounted on the outer surface of the support platform 100, a connecting rod 206b fixedly mounted on the output end of the motor 206a via a coupling, and a first gear 206c fixedly mounted on the other end of the connecting rod 206b.

[0035] It should be noted that the rotating assembly 206 also includes a second gear 206d that meshes with the surface of the first gear 206c, and the second gear 206d is fixedly connected to the outer surface of the rotating column 202.

[0036] When the motor 206a starts, it drives the first gear 206c to rotate the second gear 206d that meshes with it, and the rotating column 202 also rotates, so that the arc-shaped clamping plate 204d can rotate synchronously, thereby driving the polishing wheel 205 sleeved on its outer surface to rotate.

[0037] In use, a polishing wheel 205 of the corresponding size is placed on the outer surface of the arc-shaped clamping plate 204d, so that the inner diameter of the polishing wheel 205 contacts the outer surface of the arc-shaped clamping plate 204d. The cylinder 201 is then activated, causing the fixing sleeve 203 to move towards the conveying end of the cylinder 201. The fixing sleeve 203 causes the first guide rod 204a and the second guide rod 204c to expand by less than 90 degrees, so that the outer surface of the arc-shaped clamping plate 204d is fitted and fixed to the inner surface of the polishing wheel 205. Then, the motor 206a is started, causing the connecting rod 206b to rotate. The connecting rod 206b drives the first gear 206c to rotate, the first gear 206c drives the second gear 206d to rotate, and the second gear 206d drives the rotating column 202 to rotate, thereby driving the polishing wheel 205 to rotate. When the polishing wheel 205 needs to be replaced, the motor 206a is turned off and the cylinder 201 is turned on. The cylinder 201 drives the fixed sleeve 203 to move towards the retracted end of the cylinder 201. The fixed sleeve 203 drives the first guide rod 204a and the second guide rod 204c to approach each other at less than 90 degrees, so that the outer surface of the arc-shaped clamp 204d is released from the inner surface of the polishing wheel 205.

[0038] In summary, through the cooperation of the various components of the drive mechanism 200, the polishing wheel 205 can be securely installed on the polishing machine via the quick-change system, eliminating the need to remove the nut or the entire wheel each time it is changed. This simplifies the replacement process and makes the operation faster and more time-saving. Especially in environments where it is necessary to frequently change polishing wheels 205 of different sizes, this system improves the convenience of operation and work efficiency.
