[0025] In the existing assembly scheme, such as Figure 3 As shown, the workpiece 4' is an annular workpiece, and the guide sleeve 3' is hollow inside. When the annular workpiece is pin-assembled, the guide sleeve 3' needs to be placed on the assembly hole inside the workpiece 4', and the hollow inside the guide sleeve 3' is aligned with the assembly hole, the pin 2' is placed in the hollow inside the guide sleeve 3', and the pin 2' is pushed into the assembly hole inside the workpiece 4' by the punch 1'.

[0026] As described above, using such an assembly method will cause the contact surface of the workpiece 4' to be easily scratched due to the small contact area between the guide sleeve 3' and the workpiece 4', and because each assembly hole needs to be individually positioned and installed, it will cause a waste of assembly time.

[0028] Figure 1 FIG. 1 is a schematic diagram of a specific embodiment of a multi-station pin assembly device in the present application. Figure 1As shown, a multi-station pin assembly device is used to assemble a pin 2 for a workpiece 4, wherein the workpiece 4 is arranged in an annular shape as a whole, and an annular cone 401 extending and tilting toward the center of the annular ring is arranged around the inner ring of the workpiece 4, and the annular cone 401 is provided with a position-limited assembly hole, characterized in that the multi-station pin assembly device includes:

[0029] The pin guide component 3 has a ring-shaped body, and the inclination angle of one end face of the pin guide component 3 is the same as the inclination angle of the annular conical surface 401, so that the end face of the pin guide component 3 and the annular conical surface 401 of the inner ring of the workpiece 4 are in close contact with each other, so that the pin guide component 3 is placed inside the workpiece 4;

[0030] The other end face of the pin guide component 3 is horizontally arranged, and a penetrating guide hole is arranged between the inclined end face and the horizontal end face of the pin guide component 3, wherein the central axis direction of the guide hole is the same as the central axis direction of the assembly hole at the corresponding position on the workpiece 4;

[0031] A punch 1 is used to assemble the pin 2 placed in the guide hole on the pin guide component 3 into the assembling hole in the workpiece 4.

[0032] Specifically, the pin guide component 3 in the present application is designed for annular products, and its main purpose is to reduce the risk of scratching the annular product due to the existing assembly method, i.e., the guide sleeve, and the small contact area with the annular product. Therefore, the multi-station pin 2 assembly device is designed to meet the production needs; in the multi-station pin 2 assembly device, the pin guide component 3 is adapted to the annular workpiece 4, and the guide hole and the assembly hole are tightly stacked together. The pin 2 is placed in the guide hole on the pin guide component 3, and the pin 2 is pressed into the assembly hole on the annular workpiece 4 by the punch 1, which can achieve the purpose of improving the assembly efficiency of the annular product. Each assembly hole does not need to be positioned and installed separately, saving assembly time.

[0033] Optionally, the diameter of the guide hole is equal to the diameter of the assembly hole.

[0034] Specifically, the diameter of the guide hole is equal to the diameter of the assembly hole, so that the pin 2 placed in the guide hole will not fall off, and the pin 2 can smoothly enter the assembly hole from the guide hole.

[0035] Optionally, the number of the guide holes on the pin guide component 3 is equal to the number of the assembly holes in the workpiece 4 , and when the pin guide component 3 is placed in the workpiece 4 , the guide holes match the assembly holes.

[0036] Specifically, when the pin guide component 3 and the workpiece 4 are fitted together, each guide hole corresponds to an assembly hole, and all the pins 2 are placed in the guide holes, and the pins 2 are driven into the assembly holes one by one through the punch 1, thereby achieving the purpose of improving the assembly efficiency of the annular product and saving assembly time.

[0037] like Figure 1 As shown, the end of the workpiece 4 is placed on the table, and the pin guide component 3, the pin 2 and the punch 1 are arranged above the workpiece 4 in sequence. The inside of the workpiece 4 is an annular cone 401 with an assembly hole, the upper surface of the pin guide component 3 is a horizontal end surface, and the lower surface of the pin guide component 3 is an inclined end surface, and the inclination angle of the inclined end surface of the pin guide component 3 is the same as the inclination angle of the annular cone 401, so that the pin guide component 3 fits tightly with the annular cone 401 when in contact, and the contact area is increased. A guide hole through which a tube passes is provided between the inclined end surface and the horizontal end surface of the pin guide component 3, and the number and diameter of the guide hole are the same as those of the assembly hole, and the direction of the central axis of the two is also the same, so as to facilitate guiding the pin 2 into the assembly hole.

[0038] Optionally, the punch 1 includes: a grip portion 101, which is in the shape of a round rod and is used for hand-held force; a head 102, which is fixedly connected to the grip portion 101, the size of the head 102 is less than or equal to the diameter of the pin 2, and the head 102 assembles the pin 2 in the assembly hole by transmitting the force of the grip portion 101.

[0039] Specifically, the grip portion 101 of the punch 1 is designed to be in the shape of a round rod, which is convenient for the staff to hold and apply force, but the grip portion 101 of the punch 1 can also be designed to be other shapes that are convenient for holding. The present application provides a feasible embodiment here without making other restrictions; the size of the head 102 of the punch 1 cannot be larger than the diameter of the pin 2, so that the head 102 can extend into the guide hole to continue to apply force.

[0040] like Figure 1 As shown, the upper end of the punch 1 is a grip portion 101, and the lower end is a head 102, wherein the grip portion 101 and the head 102 are both designed to be round rod-shaped, and the diameter of the grip portion 101 is larger than the diameter of the head 102, and the diameter of the head 102 must also be less than or equal to the diameter of the pin 2, so that the punch 1 will not damage the guide hole and the assembly hole during the process of pushing the pin 2 into the assembly hole.

[0041] It should be noted that the size and shape design of the grip portion 101 only need to be able to meet the needs of the staff to hold the force, and the size and shape design of the head 102 only need to meet the needs of the smooth assembly of the pin 2. This application does not make any other restrictions.

Figure 2 As shown, the pin guide component 3 covers the annular conical surface 401 inside the workpiece 4, and the guide hole of the pin guide component 3 is concentric with the assembly hole on the annular conical surface 401 and has the same diameter. The pin 2 is placed on the guide hole of the pin guide component 3, and the pin 2 is pushed into the assembly hole on the annular conical surface 401 inside the workpiece 4 by the punch 1. In summary, the present application provides a multi-station pin 2 assembly device, which includes a pin guide component 3 and a punch 1. The pin guide component 3 is also annular, and the pin guide component 3 and the annular conical surface 401 inside the workpiece 4 have the same inclination angle, and the sizes of the two are also matched.

The pin 2 is placed in the guide hole, and the pin 2 is pushed into the assembly hole by the punch 1. The pin guide component 3 not only increases the contact area with the workpiece 4, but also simultaneously positions and installs each assembly hole on the annular cone surface 401, which reduces assembly scratches while improving assembly efficiency and adapting to production needs.
