Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model discloses a metal back cover processing fixture, including a base 1, a support seat 2, and a support plate 3. The base 1 has shaft holes 4 on both sides. A shaft 5 is embedded in the lower part of the support seat 2 and is fixed in the shaft hole 4 by a bearing. A first hand-tightening bolt 6 is threaded onto one end of the shaft 5 and is fastened to the base 1 by the first hand-tightening bolt 6. A first scale 7 is installed on the side wall of the base 1. A second scale 8 is installed on the top of the support seat 2. A rotating shaft 9 is provided at the bottom of the support plate 3 and is fixed to the support seat 2 by a bearing. A second hand-tightening bolt 10 is threaded onto the support plate 3 and is fastened to the support seat 2 by the second hand-tightening bolt 10. A dual-axis cylinder 11 and a finger-clamping cylinder 1 are respectively installed in the support seat 2. 2. The pallet 3 has a positioning groove 13, and a front clamping plate 14 and a side clamping plate 15 are respectively arranged in the positioning groove 13. The front clamping plate 14 is connected to the output end of the dual-axis cylinder 11, and the side clamping plate 15 is connected to the two clamping arms of the finger clamping cylinder 12. When the metal back cover is placed in the positioning groove 13, the front clamping plate 14 and the side clamping plate 15 are clamped and fixed by controlling the dual-axis cylinder 11 and the finger clamping cylinder 12 respectively, thus achieving the positioning of the product. When processing the metal back cover, the pitch angle of the metal back cover is adjusted by the cooperation of the first hand-tightening bolt 6 and the first scale 7, and the orientation angle of the metal back cover is adjusted by the cooperation of the second hand-tightening bolt 10 and the second scale 8, thereby changing the processing angle of the product and improving the flexibility of the processing fixture.

[0021] Specifically, one end of the shaft 5 is provided with an arc-shaped hole 16, and the head of the first hand-tightening bolt 6 is inserted into the arc-shaped hole 16 and threaded to the side wall of the base 1.

[0022] In this embodiment, the arc-shaped hole 16 serves as a clearance mechanism. When adjusting the pitch angle of the metal back cover, the first hand-tightening bolt 6 is loosened, and the pitch angle of the support plate 3 is adjusted through the cooperation between the shaft 5 and the shaft hole 4.

[0023] Specifically, the first dial 7 and the shaft 5 are located on the same axis, and the second dial 8 and the rotating shaft 9 are located on the same axis.

[0024] In this implementation scheme, the main function of the first dial 7 and the second dial 8 is to indicate the unit, range and graduation value, which can help the operator to accurately position the workpiece for processing.

[0025] Specifically, the front clamping plate 14 and the side clamping plate 15 both have a T-shaped cross-section, and the side clamping plate 15 is located at the left and right ends of the positioning groove 13.

[0026] In this embodiment, the metal back cover is placed in the positioning groove 13 (the area of ​​the positioning groove 13 is set to be larger than the area of ​​the metal back cover). The dual-axis cylinder 11 drives the front clamping plate 14 to move, so that the metal back cover is longitudinally clamped against the inner wall of the positioning groove 13. The finger clamping cylinder 12 drives the side clamping plates 15 on both sides to laterally clamp and fix the metal back cover.

[0027] Specifically, the positioning groove 13 is provided with a vertical strip hole 17, and the lower part of the front clamping plate 14 extends downward through the vertical strip hole 17 and is connected to the output end of the dual-shaft cylinder 11.

[0028] In this embodiment, the vertical strip hole 17 is a clearance structure to facilitate the displacement of the front clamping plate 14 by the dual-axis cylinder 11.

[0029] Specifically, the positioning groove 13 has horizontal strip holes 18 at both ends, and the lower part of the side clamping plate 15 extends downward through the horizontal strip holes 18 and is connected to the two clamping arms of the finger clamping cylinder 12.

[0030] In this embodiment, the transverse strip hole 18 is a clearance structure to facilitate the displacement of the side clamping plates 15 on both sides by the finger clamping cylinder 12.

[0031] In use, the metal back cover is placed in the positioning groove 13. The dual-axis cylinder 11 drives the front clamping plate 14 to move, so that the metal back cover is longitudinally clamped against the inner wall of the positioning groove 13. The clamping finger cylinder 12 drives the side clamping plates 15 on both sides to clamp and fix the metal back cover laterally, thus achieving the positioning of the product. When processing the metal back cover, the first hand-tightening bolt 6 is loosened, and the pitch angle of the support plate 3 is adjusted through the cooperation between the shaft 5 and the shaft hole 4, thereby adjusting the pitch angle of the metal back cover. Alternatively, the second hand-tightening bolt 10 is loosened, and the circumferential angle of the support plate 3 is adjusted under the action of the rotating shaft 9, thereby adjusting the orientation angle of the metal back cover. This changes the processing angle of the product and improves the flexibility of the processing fixture.

[0032] In summary, this metal back cover processing fixture places the metal back cover in the positioning groove 13. By controlling the dual-axis cylinder 11 and the finger-clamping cylinder 12 to drive the front clamping plate 14 and the side clamping plate 15 respectively, the metal back cover can be clamped and fixed, thus achieving product positioning. When processing the metal back cover, the pitch angle of the metal back cover is adjusted by the cooperation of the first hand-tightening bolt 6 and the first scale 7, and the orientation angle of the metal back cover is adjusted by the cooperation of the second hand-tightening bolt 10 and the second scale 8, thereby changing the processing angle of the product and improving the flexibility of the processing fixture.
