Description

Technical Field

[0001] The utility model relates to the field of glass processing machinery, in particular to a grinding component used for a glass edge grinding machine. Background Art

[0002] In the prior art, a glass edge grinding machine is usually used to perform edge grinding operations on glass, especially large pieces of glass. The existing glass edge grinding machines generally have a number of grinding wheels from coarse grinding to fine grinding on both sides of the edge grinding machine. The distance between each pair of grinding wheels gradually decreases from far to near according to the number of grinding wheels. However, the inventor found that the grinding wheels of the existing glass edge grinding machines will have different degrees of wear during use. Therefore, it is necessary to make different adjustments or replace the distance between each pair of grinding wheels after using them for a period of time. However, because the grinding wheels are mostly arranged inside the edge grinding machine, it is difficult for the staff to obtain the degree of wear of each grinding wheel, and then adjust the distance between different grinding wheels according to the different degrees of wear of different grinding wheels. Since the degree of wear of each grinding wheel is different, the adjustment distance or replacement cycle of different types of grinding wheels is not the same, which further increases the difficulty of adjustment for the staff. Therefore, the prior art generally adopts manual adjustment of the distance between the grinding wheels according to the work experience of the workers. However, this will rely heavily on the experience of the master, and secondly, the manual adjustment of its errors is inevitable, which will greatly reduce the service life of the grinding head and affect the quality of its glass processing. Summary of the invention

[0003] The utility model aims to provide a grinding assembly for a glass edge grinding machine, so that a worker can adjust the grinding wheel to a suitable position conveniently and quickly without knowing the wear degree of each grinding wheel.

[0004] To achieve the above purpose, the technical solution of the utility model is:

[0005] A grinding assembly for a glass edge grinding machine comprises a base, on which a motor is slidably fixed, a grinding wheel is provided at the output end of the motor, a distance adjustment mechanism is provided between the base and the motor for adjusting the front and rear position of the motor on the base, a positioning block is also fixed on the base, and the positioning block is arranged in front of the grinding wheel so that the grinding surface of the grinding wheel abuts against the positioning block when the position of the grinding wheel is adjusted to the frontmost position.

Grooves that can accommodate the triangular protrusions are provided on both sides of the slide rail on the movable platform to further enhance the sliding stability and avoid the deviation of the grinding wheel.

[0009] Preferably, the positioning block can be a positioning device such as square steel, a positioning plate, a positioning rod, etc., which can limit the grinding wheel to a fixed position and prevent it from moving forward.

[0010] Furthermore, a baffle is provided on the side of the movable table away from the positioning block, and a threaded hole is provided on the baffle so that it is threadedly connected to the rotating rod through the threaded hole.

Different from traditional manual adjustment, the present application does not need to obtain the degree of wear of each grinding wheel, but only needs to slide the movable table forward by the servo motor so that each grinding wheel abuts against the positioning block, and then move it backward by a corresponding fixed distance according to the initial data of each grinding wheel.

[0011] Preferably, nuts can be fixed on the through holes on the baffle plate as threaded holes on the baffle plate.

[0012] Furthermore, the motor and the base are connected together via a mounting plate, and the mounting plate is fixedly mounted on the base via a threaded connection.

A plurality of threaded holes are arranged on the side surfaces of the mounting plate and the base, so that the mounting plate and the side surfaces of the base can be connected together via a connecting block, so as to further increase the stability of the fixation.

[0013] Furthermore, a thrust bearing is connected between the end of the rotating rod away from the positioning block and the fixed plate, and the thrust bearing is connected to the rotating rod to further improve the axial compressive resistance of the device. Preferably, the present application connects the rotating rod to the baffle plate by using two thrust bearings, and two fixing nuts are threadedly connected to the rotating rod at the end of the thrust bearing away from the baffle plate for fastening the thrust bearing, so as to further increase its axial compressive resistance and extend the service life of the device.

[0017] Among them, the rotating rod and the output end of the servo motor can be connected through a coupling, and the connection method between the rotating shaft turntable and the output end of the motor belongs to the common knowledge of technicians in this field, so the applicant will not elaborate on it. Beneficial Effects

[0018] The present application does not need to obtain the degree of wear of each grinding wheel. It only needs to slide the movable platform forward through the distance adjustment mechanism to make each grinding wheel abut against the positioning block, and then move the corresponding fixed distance backward according to the initial data of each grinding wheel to quickly adjust the distance between multiple grinding wheels of the glass cutting machine. It can not only greatly improve the work efficiency, but also further improve the processing quality and extend the service life of the grinding wheel and the device.

[0019] Since the present application does not need to obtain the degree of wear of each grinding wheel, it only needs to slide the movable platform forward through the distance adjustment mechanism to make each grinding wheel abut against the positioning block, and then move the corresponding fixed distance backward according to the initial data of each grinding wheel to quickly adjust the distance between multiple grinding wheels of the glass cutting machine. Therefore, the present application can completely abandon the manual adjustment scheme in the prior art, and can directly control the movement of the motor through the servo motor to adjust the distance of the grinding wheels, so that it can realize the automation of grinding wheel adjustment.
