Description

Technical Field

[0001] The utility model belongs to the technical field of tool grinding equipment, in particular to a grinding tool for processing glue hanging knives. Background Art

[0002] In the process of automobile manufacturing and maintenance, manual full inspection is an important link to ensure that the quality and performance of the vehicle meet the standards. During this process, the staff will conduct detailed inspections and tests on various parts of the vehicle. Due to the glue used in the process of body repair and glass installation, it is often necessary to use a glue knife to remove the glue residue on the surface or parts of the vehicle after the repair. The glue knife is also called a glue removal knife or a car glue knife. It is mainly composed of a handle and a blade. Therefore, when grinding, the blade is mainly ground.

[0003] The Chinese patent with publication number CN219005491U discloses a blade grinding device that can grind the surfaces of multiple groups of blades at the same time, including a base, a PLC control panel is fixedly connected to the center of the front end surface of the base, a grinding bin is fixedly connected to one side of the center of the upper end surface of the base, and fixed plates are fixedly connected to both sides of the upper end surface of the base, mounting brackets are provided on the upper end surfaces of the two fixing plates, a hydraulic push rod is fixedly connected to the center of the upper end surface of the mounting bracket, the output end of the hydraulic push rod passes through the upper end surface of the mounting bracket and extends to the lower end, and multiple groups of blade fixing mechanisms are provided at the lower end of the hydraulic push rod.

[0004] However, in the actual use of traditional blade grinding equipment, we found that there are still some shortcomings. For example, when installing the blade, it is mainly clamped and fixed by a spring flap and a suction cup at the negative pressure end of the vacuum generator. The installation structure is relatively cumbersome and is only suitable for one type of fixed blade processing. Secondly, during the processing, the blade part of the tool cannot be adjusted and used according to the grinding process requirements. Therefore, the quality of the grinded product is still lacking.

[0025] The adjustment mechanism 5 includes an electric push rod 501, which is symmetrically fixedly mounted on the upper end of the mounting plate 1. The upper end of the mounting plate 1 is slidably connected to a first displacement seat 502. The output end of the electric push rod 501 is fixedly mounted to the first displacement seat 502.

A positioning column 9 is symmetrically fixedly installed on the upper end of the lower cutting die 147. In the process of clamping and fixing the blade, the positioning column 9 on the lower cutting die 147 can be used to locate the mounting hole on the blade, and then the rotary block 144 on the clamping seat 141 is operated to drive the stud 145 through the rotary block 144. The thread is retractable, and the lower end of the stud 145 rotates to push the clamp block 143 to slide, and the upper knife die 146 under the clamp block 143 cooperates with the lower knife die 147 to stably clamp the positioned tool.

When the mounting hole of the blade passes through the positioning column 9 of the lower knife die 147, when the clamp block 143 and the clamping groove 142 cooperate to clamp the blade, the upper end of the positioning column 9 on the lower knife die 147 extends into the positioning groove of the upper knife die 146, thereby facilitating the upper knife die 146 and the lower knife die 147 to combine to more stably position and clamp the blade.
