Description

Technical Field

[0001] The utility model relates to the technical field of deburring, in particular to a deburring device for the steel back of a brake. Background Art

[0002] The brake is a device that has the function of slowing down, stopping or keeping moving parts in a stopped state. The brake is mainly composed of a frame, brake parts and operating devices.

[0003] The existing Chinese patent with publication number CN218136928U discloses a brake steel back deburring device. By starting the hydraulic cylinder, the grinding head is lowered to contact the brake steel back, and the first motor is turned on to rotate the grinding head to grind and deburr the brake steel back. However, the grinding head will continue to be worn due to friction during use, resulting in a decrease in the degree of contact with the brake steel back, thereby worsening the deburring effect. Utility Model Content

[0004] The purpose of the utility model is to provide a deburring device for the steel back of a brake. By adopting the device, the problem that the grinding head is worn out due to friction during use, resulting in a decrease in the degree of fit with the steel back of the brake and a poor deburring effect is solved.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deburring device for the steel back of a brake, comprising a device box, a workbench is provided inside the device box, a clamping mechanism is provided on the inner side of the workbench, a deburring assembly is provided inside the device box, a collection box is provided on the inner side of the device box, the deburring assembly comprises a grinding mechanism, the grinding mechanism comprises a hydraulic rod, a telescopic rod is fixedly installed on the lower end of the hydraulic rod, a threaded groove is provided on the outer surface of the telescopic rod, an adjusting plate is threadedly installed on the outer side of the telescopic rod, a connecting plate is fixedly installed on the lower end of the telescopic rod, a spring is fixedly installed on the lower end of the adjusting plate, the spring is sleeved on the outer side of the telescopic rod, and is remote from the outer end of the telescopic rod. One end of the adjusting plate is fixedly connected to the upper surface of the connecting plate, and a grinding head is rotatably installed at the lower end of the connecting plate. The telescopic rod is driven down by a hydraulic rod, and the telescopic rod drives the connecting plate and the grinding head to descend, so that the grinding head contacts the steel back of the brake to achieve deburring. During the deburring process, due to the setting of the spring, it continuously generates a downward thrust on the connecting plate, forcing the grinding head to continuously and closely fit the steel back of the brake, effectively avoiding the decrease in fit due to wear, and thus the deburring effect. When the wear is too excessive, the adjusting plate can be manually adjusted to control the tightness of the spring, thereby further improving its practicality.

The two-way screw is driven to rotate by the servo motor 2, and then the two driven plates are driven to move horizontally toward the center position of the two-way screw, so that the two sets of clamping blocks can clamp and fix the brake steel back, improve the stability of the brake steel back during the deburring process, and thus improve the deburring effect. The limit block slides in the second rectangular groove, which further improves the stability of the clamping process, reduces the pressure on the two-way screw, and extends its service life.

[0009] Preferably, two sets of guide grooves are provided on the inner wall surface of the device box, a pull-out handle is fixedly installed at one end of the collection box, and slide bars are fixedly installed on both sides of the collection box, the slide bars match the guide grooves and are slidably connected, and the burrs dropped from above are collected through the collection box, which is convenient for subsequent centralized processing. The setting of the pull-out handle makes it easy for the operator to pull out and place the collection box, and the slide bars match the guide grooves and are slidably connected, reducing the labor intensity of the personnel.

[0010] Preferably, a cover is hingedly installed at one end of the device box. The cover can be opened when loading materials and closed during the deburring process to effectively prevent burrs from splashing and affecting the use environment and operators.
