detailed description

In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to FIG. 1 and FIG. 2 , an acupuncture device for battery testing, including a workbench 1 , a frame 2 , an electric cylinder 3 , a guide rod 4 , a lifting frame 5 and a needle 6 . Among them, the electric cylinder 3 is a modular product that integrates the servo motor and the lead screw, which converts the rotary motion of the servo motor into linear motion, and at the same time takes advantage of the best advantages of the servo motor - precise speed control, precise revolution control, and precise torque Control transformation into - precise speed control, precise position control, precise thrust control; realize the existing technology products of high-precision linear motion series.

The workbench 1 includes a base 1-1, a bidirectional lead screw 1-2 and two clamping blocks 1-3. The base 1-1 is the substrate of the workbench. Both ends of the two-way lead screw 1-2 are mounted on the base 1-1 through bearings, and the two clamping blocks 1-3 are fitted on the two-way lead screw 1-2 through threads. The two-way lead screw 1-2 is made up of two sections of threaded sections with opposite directions of rotation, and the two clamping movable blocks 1-3 are respectively assembled on the two sections of threaded sections of the two-way lead screw 1-2. Rotating the two-way lead screw 1-2 can realize the distance or approach of the two clamping blocks 1-3. Rotating the two-way lead screw 1-2 can make the two clamping blocks 1-3 close to each other so as to fix the battery to be tested on the workbench 1.

The frame 2 is arranged on one side of the workbench 1 . The electric cylinder 3 is installed on the top of the frame 2, and the electric cylinder 3 is the actuator for the puncture action of the needle head 6 in the device. In this embodiment, a cover is provided outside the electric cylinder 3, and the cover is fixed on the machine. on shelf 2. The electric cylinder 3 is located above the base 1-1. The electric cylinder 3 includes a lever 3-1 that can vertically expand and contract. The lower end of the lever 3-1 fixes the elevating frame 5. The needle head 6 is installed on the lower part of the lifting frame 5 . The lifting frame 5 can move vertically up and down under the driving action of the electric cylinder 3, and the lifting frame 5 is the carrier of the needle head 6, so as to realize the vertical movement of the needle head 6 driven by the electric cylinder 3. At least two guide rods 4 are mounted on the lifting frame 5, and the lower ends of the guide rods 4 are fixed on the base 1-1. The function of the guide rod 4 is to make the lifting frame 5 and the needle head 6 move up and down more smoothly, so as to ensure the running accuracy of the equipment.
