detailed description

The utility model is further described in conjunction with the accompanying drawings, see accompanying drawings 1-4.

As shown in Figures 1-4, the utility model is a multi-station mobile phone shell fixture, which includes a base 10 and several clamping mechanisms 20 arranged on the base 10. The clamping mechanism 20 includes a backing plate 21 and a cover plate 22. , fastening device 23, the backing plate 21 is fixed on the base 10, the backing plate 21 is provided with a positioning pin 211 for positioning the metal mobile phone case 50, and the cover plate 22 is provided with a positioning hole that slides and fits with the positioning pin 211 221, the cover plate 22 is dynamically connected with the positioning pin 211 through the positioning hole 221, the fastening device 23 is fixed on the base 10, first the metal mobile phone case 50 is positioned on the backing plate 21 through the positioning pin 211, and then the cover The plate 22 is installed on the positioning pin 221 through the positioning hole 221, and the cover plate 22 slides down to contact the upper surface of the metal mobile phone case 50. The sliding cooperation between the positioning hole 221 and the positioning pin 211 facilitates the installation and removal of the metal mobile phone case 50 , and finally the cover plate 22 is pressed by the fastening device 23 to prevent the movement of the product during processing and affect the processing accuracy. Through the multiple clamping mechanisms 20 provided, multiple processed products can be clamped at the same time, and multiple clamped products can be processed at one time only by one positioning and reference, which improves the processing efficiency. The structure is simple and the cost is saved.

Specifically, the base 10, the backing plate 21 and the cover plate 22 are all provided with an avoidance groove 30, the avoidance groove 30 on the base 10, the avoidance groove 30 on the backing plate 21 and the avoidance groove 30 on the cover plate 22 The position grooves 30 communicate with each other, the fastening device 23 includes a cylinder 231 and a pressing plate 233, and the piston rod 232 of the cylinder 231 respectively passes through the avoidance groove 30 on the base 10, the avoidance groove 30 on the backing plate 21 and the cover The avoidance groove 30 on the plate 22 is rotatably connected with the pressing plate 233, and the width of the avoiding groove 30 on the cover plate 22 is smaller than the length of the pressing plate 233. After the metal mobile phone case 50 is clamped and fixed, first press the pressing plate 233 is rotated to the position where the escape groove 30 of the cover plate 22 cannot pass through, and then by controlling the shrinkage of the piston rod 232 on the cylinder 231, the shrinkage of the pressure plate 233 is driven to compress the cover plate 22.
