Description

Technical Field

[0001] This invention relates to the field of grinding and polishing technology, specifically to an upper plate torsion transmission structure for a grinding and polishing device. Background Technology

[0002] In existing grinding and polishing equipment, the upper plate generally uses a movable key to transmit torque. Power is transmitted to the upper plate through a dial wheel and multiple movable keys. The outer diameter of the dial wheel is smaller than the inner diameter of the lower grinding and polishing plate. The size of the dial wheel limits the lever arm length of the torque transmission of the upper plate, which makes the contact surface between the movable key and the dial wheel subject to greater force, which can easily cause deformation of the movable key and accelerate the damage of the contact surface. Summary of the Invention

[0003] The purpose of this invention is to provide an upper plate torsion transmission structure for a grinding and polishing equipment, which adopts a relatively large diameter drive claw and drive sleeve. The size design of the drive claw and drive sleeve is no longer limited by the inner hole size of the lower grinding and polishing plate, and there is enough space to design its structure to enhance its strength. The contact surface of the drive claw and drive sleeve has a large diameter, which slows down the damage to the contact surface.

[0004] To achieve the above objectives, an upper disk torque transmission structure for a grinding and polishing device is provided, comprising a drive sleeve, wherein multiple drive sleeves are evenly distributed in a ring, and drive claws are provided between the multiple drive sleeves, wherein multiple drive claws are staggered with the drive sleeves, a drive disk is fixedly connected to the bottom of the drive claws, an upper grinding and polishing disk is fixedly connected to the bottom of the drive disk, a joint bearing seat and a connecting disk are provided inside the drive disk, and an adapter plate is provided above the joint bearing seat and the connecting disk.

[0005] According to the upper plate torsion transmission structure of the grinding and polishing equipment, the bottom of the drive sleeve is fixedly connected to the drive plate.

[0006] According to the upper plate torque transmission structure of the grinding and polishing equipment, the drive sleeve is in contact with the side wall of the drive claw. This differs from traditional dial and key structures, instead employing a torque transmission structure of a drive sleeve and drive claw.

[0007] According to the upper plate torsion transmission structure of the grinding and polishing equipment, the drive plate is located at the center of the upper grinding and polishing plate.

[0008] According to the upper plate torque transmission structure of the grinding and polishing equipment, the joint bearing seat and the connecting plate are fixedly connected by an adapter plate, which is located below the drive claw.

[0009] According to the upper plate torque transmission structure of the grinding and polishing equipment, the drive sleeve is fixedly connected to the outer upper plate rotating shaft.

[0010] Compared with the prior art, the beneficial effects of the present invention are: by setting up a drive sleeve, drive claw, drive disk, upper grinding and polishing disk, joint bearing seat, adapter plate and connecting disk, and using drive claw and drive sleeve with relatively large diameter, the size design of drive claw and drive sleeve is no longer limited by the inner hole size of the lower grinding and polishing disk, and there is enough space to design its structure to enhance its strength. The contact surface of its drive claw and drive sleeve has a large diameter, which slows down the damage to the contact surface.

[0011] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-2This invention provides a technical solution: an upper plate torque transmission structure for a grinding and polishing device, comprising multiple drive sleeves 1 evenly distributed in a ring, each drive sleeve 1 fixedly connected to an external upper plate rotating shaft, a synchronous pulley mounted above the upper plate rotating shaft, the synchronous pulley being connected to an upper plate rotation drive motor via a synchronous belt, allowing the drive sleeves 1 to rotate when the drive motor is started, and multiple drive claws 2 staggered among the drive sleeves 1, with a drive disk 3 fixedly connected to the bottom of each drive claw 2, and the bottom of each drive sleeve 1 fixedly connected to the drive disk 3, the drive sleeves 1 and the drive claws 2... The sidewall fits snugly, unlike the traditional dial and key structure. Instead, it adopts a torque transmission structure of drive sleeve 1 and drive claw 2, which is no longer limited by the inner hole size of the lower grinding and polishing disc. There is enough space to design its structure to enhance its strength. The contact surface of drive claw 2 and drive sleeve 1 has a large diameter, which slows down the damage to the contact surface. The bottom of drive disc 3 is fixedly connected to upper grinding and polishing disc 4. Drive disc 3 is located at the center of upper grinding and polishing disc 4. The interior of drive disc 3 is provided with spherical bearing seat 5 and connecting disc 7. The upper part of spherical bearing seat 5 and connecting disc 7 is provided with adapter plate 6. Spherical bearing seat 5 and connecting disc 7 are fixedly connected by adapter plate 6. Adapter plate 6 is located below drive claw 2.

[0018] Working principle: The drive sleeve 1 is installed on the upper plate rotating shaft. A synchronous pulley is installed above the upper plate rotating shaft. The synchronous pulley is connected to the upper plate rotation drive motor through a synchronous belt. The torque transmission contact surface below the drive sleeve 1 contacts the side of the drive claw 2, thereby driving the upper grinding and polishing disc 4 to rotate and grind the upper surface of the workpiece. The drive sleeve 1 fits against the side wall of the drive claw 2. Unlike the traditional dial and key structure, it is no longer limited by the inner hole size of the lower grinding and polishing disc. There is enough space to design its structure to enhance its strength. The contact surface between the drive claw 2 and the drive sleeve 1 has a large diameter, which slows down the damage to the contact surface.

[0019] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
