[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 A multi-station pressing fixture for rubber sealing rings includes a worktable 1 and a pressing equipment body 2. A rotating shaft 3 is rotatably connected to the upper end face of the worktable 1, and a turntable 4 is fixedly connected to the upper end of the rotating shaft 3. Multiple workpiece positioning mechanisms are arranged in an array on the upper end face of the turntable 4.

[0023] The workpiece positioning mechanism includes a positioning pin 5 fixedly connected to the upper end face of the turntable 4. The positioning pin 5 has a cavity 6 inside. The outer wall of the positioning pin 5 has multiple arrayed through holes 7. Clamping blocks 8 are slidably connected inside the multiple through holes 7. A moving rod 9 is provided inside the cavity 6. The moving rod 9 and the multiple clamping blocks 8 are movably connected by a pull rod 10 through a hinge.

[0024] In this embodiment: the workpiece has an inverted T-shaped cross-section and a hollow interior. During use, the workpiece is fitted onto the outside of the positioning pin 5. Then, the rotating shaft 3 rotates 90 degrees, causing the turntable 4 to rotate, thus swapping the positions of the multiple positioning pins 5. During rotation, the positioning pins 5, in conjunction with the moving rod 9, drive multiple support wheels 13 to move on the upper surface of the support ring 11. Simultaneously, one support wheel 13 located in the inclined groove 12 moves out of the inclined groove 12 and, through the inclined structure of the inclined groove 12, pushes the support wheel 13 upwards to the upper surface of the support ring 11. At this time, one support wheel 13 in the inclined groove 12 pushes a corresponding moving rod 9 upwards, and, in conjunction with multiple corresponding pull rods 10, pushes multiple corresponding clamping blocks 8 to move in opposite directions, causing the clamping blocks 8 to abut against the inner wall of the workpiece, thereby clamping and limiting the workpiece. Simultaneously, one support wheel 13 located in the rear direction of rotation moves into the interior of the inclined groove 12 and, through gravity... Moving downwards, a support wheel 13 located behind the rotation direction drives a corresponding moving rod 9 to move downwards, and cooperates with multiple corresponding pull rods 10 to pull multiple corresponding clamping blocks 8 to move relative to each other, thereby releasing the clamping state of multiple clamping blocks 8 on the workpiece, so as to replace the workpiece on the positioning pin 5. When the turntable 4 drives one of the workpieces to rotate to the bottom of the pressing equipment body 2, since the center point of the pressing equipment body 2 and the center point of one of the workpiece positioning mechanisms located below the pressing equipment body 2 are on the same vertical line, the center point of the pressing equipment body 2 and the center point of the workpiece are on the same vertical line. Then the pressing equipment body 2 moves downwards, and performs the pressing operation of the rubber sealing ring on the workpiece through the pressing equipment body 2. After the pressing is completed, the pressing equipment body 2 moves upwards to reset, and repeats the above steps. Thus, the production process is streamlined through multi-station design, and loading and unloading and pressing are carried out simultaneously, effectively improving production efficiency.

[0025] As a technical optimization of this utility model, the upper end face of the workbench 1 is fixedly connected to a support ring 11 located below the turntable 4. The upper end face of the support ring 11 has a sloping groove 12 on the front side. The lower end of the moving rod 9 extends to the lower part of the turntable 4 and is fixedly connected to a support wheel 13 that matches the support ring 11 and the sloping groove 12. The moving rod 9 is slidably connected to the turntable 4.

[0026] In this embodiment: through the cooperation between the support ring 11 and the inclined groove 12, the multiple support wheels 13 can move up and down during the movement of the multiple support wheels 13. The support wheels 13 can reduce the friction between the lower end of the moving rod 9 and the support ring 11, so that the moving rod 9 can move smoothly.

[0027] As a technical optimization of this utility model, a top plate 14 is provided above the turntable 4, and the pressing equipment body 2 is installed on the lower end face of the top plate 14. The center point of the pressing equipment body 2 and the center point of one of the workpiece positioning mechanisms located below the pressing equipment body 2 are on the same vertical line. Two electric telescopic rods 15 distributed on the left and right are installed between the top plate 14 and the worktable 1.

[0028] In this embodiment, the electric telescopic rod 15 and the top plate 14 work together to drive the pressing equipment body 2 to move vertically.

[0029] As a technical optimization of this utility model, a stepper motor 16 is installed on the lower end face of the workbench 1, and the output end of the stepper motor 16 is fixedly connected to the rotating shaft 3.

[0030] In this embodiment, the stepper motor 16 can drive the rotating shaft 3 to rotate.

[0031] As a technical optimization of this utility model, the outer wall of the moving rod 9 is fixedly connected to a limiting block 17 located inside the cavity 6.

[0032] In this embodiment, the moving distance of the moving rod 9 can be limited by the limiting block 17.

[0033] As a technical optimization of this utility model, anti-slip textures are provided on the opposite side walls of the multiple clamping blocks 8.

[0034] In this embodiment, the anti-slip texture can increase the friction between the workpiece and the multiple clamping blocks 8, thus clamping the workpiece more stably.

[0035] As a technical optimization of this utility model, the pressing equipment body 2, the two electric telescopic rods 15 and the stepper motor 16 are all electrically connected to an external control computer.

[0036] In this embodiment, an external control computer facilitates the control of the pressing equipment body 2, the two electric telescopic rods 15, and the stepper motor 16.

[0037] The working principle and usage process of this utility model are as follows: In use, the workpiece is sleeved onto the outside of the positioning pin 5. Then, the stepper motor 16 drives the rotating shaft 3 to rotate 90 degrees. The rotating shaft 3 drives the turntable 4 to rotate, causing the positions of multiple positioning pins 5 to interchange. During rotation, the positioning pins 5, in conjunction with the moving rod 9, drive multiple support wheels 13 to move on the upper end face of the support ring 11. Simultaneously, one support wheel 13 located in the inclined groove 12 moves out of the inclined groove 12 and, through the inclined structure of the inclined groove 12, pushes the support wheel 13 upward, moving it to the upper end face of the support ring 11. At this time, one support wheel 13 located in the inclined groove 12 pushes a corresponding moving rod 9 upward, and, in conjunction with multiple corresponding pull rods 10, pushes multiple corresponding clamping blocks 8 to move in opposite directions, causing the multiple clamping blocks 8 to abut against the inner wall of the workpiece, thereby clamping and limiting the workpiece. At the same time, the positioning pins 5, in conjunction with the moving rod 9, drive multiple support wheels 13 to move on the upper end face of the support ring 11. A support wheel 13 located behind the rotating direction moves into the interior of the inclined groove 12 and moves downward by gravity. At this time, the support wheel 13 located behind the rotating direction drives a corresponding moving rod 9 to move downward, and cooperates with multiple corresponding pull rods 10 to pull multiple corresponding clamping blocks 8 to move relative to each other, thereby releasing the clamping state of multiple clamping blocks 8 on the workpiece, so as to replace the workpiece on the positioning pin 5. When the turntable 4 drives one of the workpieces to rotate to the bottom of the pressing equipment body 2, the electric telescopic rod 15 cooperates with the top plate 14 to drive the pressing equipment body 2 to move downward. The pressing equipment body 2 performs the pressing operation of the rubber sealing ring on the workpiece. After the pressing is completed, the pressing equipment body 2 moves upward to reset and repeats the above steps. Thus, the production process is streamlined through the multi-station design, and the loading and unloading and pressing are carried out simultaneously, effectively improving production efficiency.
