Description

Clamping device for wedge processing

technical field

The utility model relates to a fixture, more specifically, it relates to a convenient clamping device for wedge processing.

Background technique

In the process of changing the hole position or increasing the number of holes in the stamping part, in order to reduce the production cost and processing time of the stamping factory, generally no special wedge device will be purchased, but the punch fixing plate of the original wedge device In order to fix the increased punch on the punch fixing plate of the original wedge device, it is necessary to use a drilling machine to drill holes on the punch fixing plate. Due to the special structure of the wedge device, no matter how it is placed, it is impossible to make the wedge punch through the head fixing plate and the workbench of the drilling machine at a horizontal angle, so that the punch fixing plate cannot be directly punched. At present, the method of stacking iron blocks is generally used to solve this problem. First, manually maintain the punch fixing plate at the same horizontal position as the drilling machine table, and then another operator takes the corresponding iron block, and uses the iron block to hold the inclined The angle formed by the bottom of the wedge device and the worktable is fully overlapped, so that the punch fixing plate can always be kept in a horizontal position, which is convenient for the next step of drilling. Although this can solve the problem that the punch fixing plate cannot keep level with the drilling machine workbench, the operation process is cumbersome and has potential safety hazards. Since there is no corresponding fixing device, corresponding vibration will inevitably occur during the drilling process, and the perpendicularity between the hole position and the punch fixing plate cannot be guaranteed; what is more serious is that during the drilling process, when the drill bit jams When in the punch fixing plate, due to the high-speed rotation of the drill bit, the entire wedge device will inevitably move together, which may cause the previously stacked iron blocks to fly off the workbench and cause a safety accident.

Chinese patent announcement number CN202825263U discloses a clamp for clamping a wedge on an automobile mold, including a base, a baffle, an auxiliary pad and a clamping screw, the baffle is vertically fixed on the base, and the auxiliary pad The block is placed on the base parallel to the block, the wedge is placed in the base and between the baffle and the auxiliary pad, the auxiliary pad is placed on the lower part of the wedge and is in contact with the wedge, and the base There are also two parallel side plates located on both sides of the wedge, and clamping screws pass through the side plates to clamp the wedge. The jig with this structure clamps the wedge through the clamping screw. The clamping effect is not ideal, and it is easy to damage the wedge. safety hazard.
