Description

Machining clamp for current collector Technical Field The utility model belongs to the technical field of current collector machining, and particularly relates to a machining clamp for a current collector. Background The current collector is a component used for collecting and conducting current in the fields of batteries and the like, and plays a key role in the normal operation and performance of the device. In the kylin battery, the current collector is tightly matched with the water cooling plate, the 36pcs water cooling plate is matched with 72 current collectors to form a group, and the current collectors are arranged on two sides of the water cooling plate. The current common current collector processing mode is that a blank is clamped by a bolt and a clamping plate, the clamping plate is installed on a machine tool by the bolt, the blank is milled, and when a large number of blanks are processed, the clamping process is time-consuming and labor-consuming. Disclosure of utility model The utility model aims to provide a processing clamp for a current collector, which is characterized in that a piston rod of a rotary cylinder drives a compression head to fix a carrier plate instead of a bolt fixing method, so that on one hand, the convenience of installation can be increased, the efficiency is improved, and on the other hand, the carrier plate can be replaced according to the shape of a processed blank, so that the application range of processing can be increased. In order to achieve the technical purpose, the technical scheme of the utility model is as follows: the utility model provides a machining fixture for current collector, includes base and support plate, be equipped with the revolving cylinder on the base, be equipped with on the revolving cylinder piston rod and compress tightly the head, be equipped with the draw-in groove on the support plate, be equipped with the through-hole that supplies to compress tightly the head to penetrate on the groove diapire of draw-in groove, compress tightly the head and pass the through-hole and compress tightly the tank bottom wall of draw-in groove. When processing, firstly install the base on the lathe, install the stock on the carrier plate, place the carrier plate on the base again, compress tightly the headgear in the through-hole, revolving cylinder drives and compresses tightly the rotatory pushing down of head, compress tightly the head and compress tightly on the groove diapire of draw-in groove to can fix the carrier plate on the base, with this fixed carrier plate that can convenient and fast improves installation effectiveness, also can install different carrier plates according to stock shape in addition, be favorable to increasing the application scope of processing part. In a specific implementation mode, one side of the carrier plate is provided with a mounting notch, the mounting notch is communicated with the clamping groove, a locking plate is arranged at the mounting notch, the locking plate is attached to the mounting notch, and the locking plate is connected with the carrier plate through a bolt. When the blank is installed, the blank is inserted into the clamping groove, the locking plate is attached to the installation notch, and the locking plate is locked and installed by the bolts, so that the stability of the installation of the blank can be enhanced. In a specific embodiment, the height of the locking plate is lower than the maximum height of the carrier plate, and the distance between the locking plate and the carrier plate is 3-5 mm. The highest position of the locking plate is lower than the maximum height of the carrier plate, so that a processing space can be provided, processing is facilitated, the installation of blanks can be prevented from being influenced, and chip removal is facilitated.
