Clamping device with compensation function for flexible plastic lamp punching equipment

Abstract

The invention discloses a material clamping device with a compensation function for flexible plastic lamp punching equipment in the technical field of lamp machining equipment, the material clamping device comprises a workbench, a rack and a punching device, a hydraulic rod at the bottom of a hydraulic cylinder extends into an inner cavity of the rack and is fixedly connected with the punching device, and a supporting plate is fixedly mounted on the outer wall of the right side of the top of the workbench; two sets of sliding grooves are formed in the outer wall of the top of the supporting plate, compensation devices are slidably inserted into the top ends of inner cavities of the sliding grooves, clamping plates are arranged on the outer walls of the sides, close to each other, of the two sets of compensation devices, and through expansion of supporting springs in the devices, moving blocks drive the clamping plates to move towards the inner side; the clamping plates can continuously provide stable supporting force for the lamp shell, the situation that the lamp shell is sunken towards the middle of the supporting plate when being extruded, and consequently the clamping plates make insufficient contact with the lamp shell is avoided, the lamp shell cannot accidentally move in the machining process, and the machining accuracy of the lamp shell is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lamp processing equipment, in particular to a clamping device for flexible plastic lamp punching equipment with a compensation function. Background technique [0002] When the lamp is processed, it is necessary to punch holes in the shell of the lamp. When the existing lamp shell is processed, in order to ensure that the lamp shell will not move during processing, the processed lamp shell needs to be fixed, usually by two sets of splints. Close to each other and fit the lamp shell, and fix the lamp shell on the workbench. However, when processing and punching the flexible plastic lamp shell, the punch of the punching device needs to move down to punch holes on the surface of the lamp shell. , the downward movement of the punch will press down on the lamp shell, because the flexible plastic lamp shell will deform and bend when it is squeezed, causing the lamp shell to sag towards the perforated area, causi...

[0002] When the lamp is processed, it is necessary to punch holes in the shell of the lamp. When the existing lamp shell is processed, in order to ensure that the lamp shell will not move during processing, the processed lamp shell needs to be fixed, usually by two sets of splints. Close to each other and fit the lamp shell, and fix the lamp shell on the workbench. However, when processing and punching the flexible plastic lamp shell, the punch of the punching device needs to move down to punch holes on the surface of the lamp shell. , the downward movement of the punch will press down on the lamp shell, because the flexible plastic lamp shell will deform and bend when it is squeezed, causing the lamp shell to sag towards the perforated area, causing the edge of the lamp shell to move inward, causing the lamp The pressure between the shell and the splint is reduced, so that there is insufficient contact between the splint and the lamp shell, resulting in weakened fixing effect of the splint on the lamp shell, making the lamp shell easy to move during processing, and the processing of the lamp shell Therefore, we propose a clamping device for flexible plastic lamp punching equipment with compensation function
