One end of the long pressing plate is slidably connected to the supporting sliding seat fixedly installed on the base. The other end of the long pressing plate is rotatably installed with the inclined pressing plate. The inclined pressing plate is located above the inner positioning block fixedly installed on the base. The low positioning seat, the lever cylinder and the lifting support seat are arranged around the inner positioning block. The lower end of the lifting support seat slides through the base and into the inclined block seat. The inclined block seat is fixedly installed on the lower side of the base. The inclined block seat is located on one side of the first cylinder, the lever cylinder and the third cylinder. The output end of the conveying third cylinder is fixed to the movable inclined block. The movable inclined block is slidably installed in the inclined block seat.

[0006] Preferably, the long pressing plate is of a long rectangular structure. The inclined pressing plate rotatably installed on the long pressing plate is calibrated with the upper inclined base surface of the left bracket. The first cylinder applies a downward pressure to the left bracket through the long pressing plate, the inclined pressing plate and the pressing block of the lever cylinder. The output end of the second cylinder applies a side pressure to the left bracket.

[0007] Preferably, the end faces of the inner positioning block, the low positioning seat and the lifting support seat are calibrated with the lower base surface of the left bracket.

[0018] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0019] A left bracket positioning and clamping structure provided by the utility model includes a base 1, a first cylinder 2, a second cylinder 3, a long pressing plate 4, a supporting sliding seat 5, an inclined pressing plate 6, an inner positioning block 7, a low positioning seat 8, a lever cylinder 9, a lifting support seat 10, an inclined block seat 11, a movable inclined block 12, a third cylinder 13 and a left bracket 14. The first cylinder 2, the second cylinder 3, the lever cylinder 9 and the third cylinder 13 are fixedly installed on the base 1. The output end of the first cylinder 2 is fixed to the long pressing plate 4. One end of the long pressing plate 4 is slidably connected to the supporting sliding seat 5 fixedly installed on the base 1. The other end of the long pressing plate 4 is rotatably installed with the inclined pressing plate 6. The inclined pressing plate 6 is located above the inner positioning block 7 fixedly installed on the base 1. The low positioning seat 8, the lever cylinder 9 and the lifting support seat 10 are arranged around the inner positioning block 7. The lower end of the lifting support seat 10 slides through the base 1 and penetrates into the inclined block seat 11. The inclined block seat 11 is fixedly installed on one side below the base 1. The inclined block seat 11 is located on one side of the first cylinder 2, the lever cylinder 9 and the third cylinder 13. The output end of the third cylinder 13 is fixed to the movable inclined block 12. The movable inclined block 12 is slidably installed in the inclined block seat 11;

[0020] The left bracket 14 is positioned and clamped by a positioning fixture tooling. The base 1, the first cylinder 2, the second cylinder 3, the long pressing plate 4, the supporting sliding seat 5, the inclined pressing plate 6, the inner positioning block 7, the low positioning seat 8, the lever cylinder 9, the lifting support seat 10, the inclined block seat 11, the movable inclined block 12 and the third cylinder 13 are the positioning fixture tooling.

[0021] Example 1:

[0022] Specifically, the long pressing plate 4 is designed as a long rectangular structure to ensure sufficient rigidity and stability when applying pressure. The inclined pressing plate 6 is rotatably installed on the long pressing plate 4, and it is fully calibrated with the upper inclined base surface of the left bracket 14. When the first cylinder 2 is started, its output end pushes the long pressing plate 4 to move downward, and then drives the inclined pressing plate 6 to closely adhere to the inclined base surface of the left bracket 14. At the same time, the pressing block of the lever cylinder 9 also participates in applying the downward pressure, and together with the long pressing plate 4 and the inclined pressing plate 6, it realizes the stable downward pressing of the left bracket 14.

[0023] Specifically, the end faces of the inner positioning block 7, the low positioning seat 8 and the lifting support seat 10 are calibrated with the lower base surface of the left bracket 14. The end face of the inner positioning block 7 is calibrated with the lower base surface of the left bracket 14 to provide the main positioning support. Around the inner positioning block 7, three low positioning seats 8 are respectively arranged. These low positioning seats 8 are in an inverted "T" shape structure, which can further stabilize the position of the left bracket 14 and prevent it from shifting during the processing or assembly process.

[0024] Specifically, the lower end of the lifting support base 10 passes through the base 1 and extends into the inclined block seat 11. The inclined block seat 11 is provided with a special groove body that allows the lifting support base 10 to move up and down. In addition, the groove body also allows the movable inclined block 12 to slide horizontally. The inclined surface provided at the lower end of the lifting support base 10 closely cooperates with the inclined surface of the movable inclined block 12. When the cylinder three 13 is started, by pushing the movable inclined block 12 to slide horizontally, the mutual acting force between the inclined surfaces is utilized to realize the up and down movement of the lifting support base 10. This design not only simplifies the structure but also improves the accuracy and stability of the lifting.

[0025] Embodiment 2:

[0026] First, place the left bracket 14 on the positioning fixture tooling so that its lower base surface is roughly aligned with the end faces of the inner positioning block 7, the low positioning seat 8, and the lifting support base 10. Start the cylinder three 13 to push the movable inclined block 12 to slide horizontally in the groove body of the inclined block seat 11. Since the movable inclined block 12 closely cooperates with the inclined surface at the lower end of the lifting support base 10, the horizontal movement of the movable inclined block 12 will drive the lifting support base 10 to rise until its end face contacts the lower base surface of the left bracket 14, realizing preliminary positioning. Then, start the cylinder one 2, and its output end pushes the long pressing plate 4 to slide downward along the support slide seat 5. The movement of the long pressing plate 4 drives the inclined pressing plate 6 to gradually approach and closely adhere to the upper inclined base surface of the left bracket 14, realizing precise calibration of the inclined surface. At the same time, the pressing block of the lever cylinder 9 also starts to apply a downward pressure, acting together with the long pressing plate 4 and the inclined pressing plate 6 to apply a stable downward pressure to the left bracket 14. The output end of the cylinder two 3 applies a lateral pressure to the left bracket 14 to further stabilize its position. At this time, the left bracket 14 is precisely positioned and clamped by the positioning fixture tooling jointly formed by the inner positioning block 7, the low positioning seat 8, the lifting support base 10, and the long pressing plate 4, the inclined pressing plate 6, and the lever cylinder 9. The inverted "T" - shaped structure of the low positioning seat 8 provides additional stability to prevent the left bracket 14 from shifting during processing or assembly. After the left bracket 14 is stably clamped, subsequent processing or assembly operations can be carried out. After the processing or assembly is completed, turn off the cylinder two 3, the lever cylinder 9, and the cylinder one 2 in sequence to release the clamping of the left bracket 14 by the positioning fixture tooling. Then, by operating the cylinder three 13 in the reverse direction, the lifting support base 10 descends, and finally the left bracket 14 is taken out from the positioning fixture tooling.

[0027] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design similar technical solutions and achieving the above - mentioned technical effects all fall within the protection scope of the present utility model.
