[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] A double positioning press pin fixture, such as Figures 1-4As shown, the assembly includes a base plate 1, a connecting assembly 2, a workpiece base 3, a quick clamp 4, a guide assembly 5, and a limit assembly 6 disposed on the base plate 1. The workpiece base 3 is connected to the guide assembly 5, which guides the workpiece base 3 in horizontal movement. The quick clamp 4 is connected to the workpiece base 3 via the connecting assembly 2, driving the workpiece base 3 to move via the quick clamp 5. The limit assembly 6 limits the stopping position of one end of the workpiece base 3. The quick clamp 4 has two states: closed and open. One state is selected as the reference positioning point, and the other limit point is adjusted by the limit assembly 6 to achieve dual positioning of the workpiece.

[0021] In one embodiment, if Figures 1-4 As shown, the guide assembly 5 includes a guide rod 51 and first supports 52 disposed on either side of the guide rod 51. The first supports 52 are fixed to the base plate 1. The guide rod 51 is used to guide the movement of the workpiece base 3. The workpiece base 3 is supported on the base plate 1 to withstand the pressure of the press pin of the hand stacking machine. The guide rod 51 guides the workpiece base 3 to adjust its horizontal position. Specifically, the workpiece base 3 is provided with a guide hole, and the guide rod 51 is disposed within the guide hole. The ends of the guide rod 51 are fixed to the first supports 52.

[0022] In one embodiment, if Figures 1-4 As shown, the limit assembly 6 includes a second support 61, an adjustment rod 62, and a limit plate 63. The second support 61 is fixed to the base plate 1. The adjustment rod 62 is threadedly engaged with the second support 61. The limit plate 63 is fixed to one end of the adjustment rod 62. The horizontal position of the limit plate 63 is adjusted by rotating the adjustment rod 62. The limit plate 63 is used to define the stop position of the right movement of the workpiece base 3.

[0023] In the above embodiment, if Figures 1-4 As shown, the limiting plate 63 is a magnet. Correspondingly, the workpiece base 3 is usually made of iron, and the magnetic limiting plate 63 is used to adsorb the workpiece base 3 so that the workpiece base 3 is kept in the stopped position.

[0024] In the above embodiment, if Figures 1-4 As shown, a first locking nut 64 is provided on the adjusting rod 62. During use, the first locking nut 64 is tightened on the second support 61 to prevent the adjusting rod 62 from becoming loose and dislocating during use.

[0025] In the above embodiment, if Figures 1-4 As shown, a connecting hole is radially provided on the adjusting rod 62, and a driving rod 65 is provided in the connecting hole. The driving rod 65 is convenient for controlling the rotation of the adjusting rod 62 to adjust the horizontal position of the limiting plate 63.

The fixing rod 21 is arranged on the quick clamp 4. The fixing rod 21 has an axially recessed connecting hole. The connecting rod 22 is threadedly engaged with the connecting hole. The second locking nut 23 is arranged on the connecting rod 22, and the connecting rod 22 is connected to the workpiece base 3. Specifically, a connecting groove 31 with at least one end open is provided on the workpiece base 3, and a connecting portion is provided on the connecting rod 22, which is placed in the connecting groove 31. The connecting portion is a radially protruding flange, and the cross-section of the connecting groove 31 is T-shaped. Placing the connecting portion in the connecting groove 31 with a T-shaped structure can facilitate the connection between the connecting rod 22 and the workpiece base 3.

[0027] When the utility model is used, Figures 1-4 As shown, the quick clamp 4 is moved to the open position, and the connecting rod 22 is rotated to adjust the initial position of the workpiece base 3 so that the upper die of the hand stacking machine is aligned with a pin hole on the right side; then the limit assembly 6 is adjusted, and the quick clamp 4 is moved to push the workpiece base 3 to the right, and the workpiece base 3 is pressed against the limit plate 63, and then the adjustment rod 62 is rotated to push the workpiece base 3 to the left so that the upper die of the hand stacking machine is aligned with a small shaft hole on the left side of the product. Then the first locking nut 64 is rotated to lock the adjustment rod 62. After the adjustment is completed, the pin press-fitting is started, the workpiece is placed on the workpiece base 3, and then the quick clamp 4 is moved to the open state. The press-fitting of one pin is completed by the hand stacking machine, and then the quick clamp 4 is moved to move the workpiece base 3 to the right and the workpiece base 3 is pressed against the limit plate 63, and then the press-fitting of the second pin is completed.
