Right-angle sliders are symmetrically installed on the bottom of the lower clamping plates and mounted on a T-shaped slide rail of a pressing device. The upper and lower workpieces have inclined folded plate cross-sections. A workpiece limiting groove and an oblique circular limiting protrusion are provided on the lower clamping plate corresponding to the lower workpiece. The lower workpiece is fastened onto the workpiece limiting groove and the oblique circular limiting protrusion. The oblique circular limiting protrusion corresponds to the inclination angle of the lower workpiece, preventing interference with the upper workpiece during bonding. The upper workpiece presses over the lower workpiece. A workpiece groove is provided on the lower surface of the upper clamping plate, with the shape of the workpiece groove corresponding to that of the upper workpiece.
[0005] As a preferred embodiment of this utility model, position sensing plates are fixedly installed on both sides of the lower clamping plate.

[0007] As a preferred embodiment of this utility model, the oblique square limiting protrusion and the oblique circular limiting protrusion are both symmetrically arranged in twos.
[0008] As a preferred embodiment of this utility model, an arc-shaped support block is installed on the lower clamping plate corresponding to the lower edge of the lower half of the workpiece to provide surface support and prevent the workpiece from being crushed.
[0009] As a preferred embodiment of this utility model, the upper end of the positioning hole is provided with an outwardly flared chamfer to facilitate the mounting of the positioning post of the fixture.
[0010] By adopting the above technical solution, this utility model has the following beneficial effects:
[0011] This invention, through the cooperation of the fixture positioning pin and positioning hole, and the setting of workpiece limiting groove, oblique circular limiting protrusion and oblique square limiting protrusion, can accurately position the upper and lower halves of the workpiece, improving the precision of the bonding process. The oblique circular limiting protrusion avoids interference with the upper workpiece, and the arc-shaped support block provides surface support for the workpiece, effectively preventing the workpiece from being crushed during the clamping process, thus improving the product yield. The right-angle slider at the bottom of the lower clamping plate cooperates with the T-shaped slide rail of the clamping equipment to make the fixture move smoothly. The cooperation between the position sensing plate and the sensor realizes the automatic operation of the clamping equipment, improving production efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example 1
[0020] like Figures 1 to 5 As shown, a specific embodiment of the special fixture for bonding and processing automotive interior panels according to this utility model includes: a lower clamping plate 1 and an upper clamping plate 2; fixture positioning posts 6 are installed at both ends of the upper clamping plate 2, and positioning holes 7 are opened on the lower clamping plate 1 corresponding to the fixture positioning posts 6. The lower clamping plate 1 and the upper clamping plate 2 are set as two sets, and the two lower clamping plates 1 are fixedly connected by a connecting plate 3 in the middle position. Right-angle sliders 8 are symmetrically installed at the bottom of the lower clamping plate 1, and the right-angle sliders 8 are installed on the T-shaped slide rail of the pressing equipment.
[0021] The upper part 12 and the lower part 13 have inclined folded plate structures in cross-section. The lower clamping plate 1 has a workpiece limiting groove 5 and an oblique circular limiting protrusion 9 corresponding to the lower part 13. The lower part 13 is fastened to the workpiece limiting groove 5 and the oblique circular limiting protrusion 9. The oblique circular limiting protrusion 9 can correspond to the tilt angle of the lower part 13 to avoid interference with the upper part 12 during bonding processing. The upper part 12 presses on the upper part 13. The upper part 12 and the lower part 13 are pressed and fixed by glue. The lower surface of the upper clamping plate 2 has a workpiece groove, and the shape of the workpiece groove corresponds to that of the upper part 12.
[0022] Furthermore, position sensing plates 4 are fixedly installed on both sides of the lower clamping plate 1. The position sensing plates 4 are set to correspond to the sensors on the hydraulic clamping equipment. When the position sensing plates 4 move to the sensor position, the hydraulic clamping equipment is activated to perform the clamping operation.
[0023] Furthermore, a slanted square limiting protrusion 10 is fixedly installed on the lower clamping plate 1, and the slanted square limiting protrusion 10 is set to the hole position in the middle of the lower half of the workpiece 13.
[0024] Furthermore, both the oblique square limiting protrusion 10 and the oblique circular limiting protrusion 9 are symmetrically arranged in twos;
[0025] Furthermore, an arc-shaped support block 11 is installed on the lower clamping plate 1 corresponding to the lower edge of the lower half of the workpiece 13 to provide surface support and prevent the workpiece from being crushed.
[0026] Furthermore, the upper end of the positioning hole 7 is provided with an outwardly flared chamfer to facilitate the installation of the fixture positioning post 6.
[0027] The working principle of this utility model is as follows: The lower half of the workpiece 13 is fastened onto the workpiece limiting groove 5 and the oblique circular limiting protrusion 9 of the lower clamping plate 1. The oblique circular limiting protrusion 9 corresponds to the tilt angle of the lower half of the workpiece 13, ensuring accurate placement of the lower half of the workpiece 13. At the same time, the oblique square limiting protrusion 10 is inserted into the hole in the middle of the lower half of the workpiece 13 to further improve the positioning accuracy. Then, glue is applied, and the upper half of the workpiece 12 is pressed on top of the lower half of the workpiece 13. The fixture is pushed so that the bottom of the lower clamping plate 1... The right-angle slider 8 slides on the T-shaped slide rail. When the position sensing plates 4 on both sides of the lower clamping plate 1 move to the sensor position on the hydraulic clamping device, the sensor sends a signal, and the hydraulic clamping device is activated to press down the upper clamping plate 2, so that the upper half of the workpiece 12 and the lower half of the workpiece 13 are tightly fitted together. During the clamping process, the arc-shaped support block 11 on the lower clamping plate 1 provides surface support for the lower edge of the lower half of the workpiece 13 to prevent the workpiece from being crushed. After the bonding process is completed, the hydraulic clamping device rises, lifts the upper clamping plate 2, and removes the workpiece.
