[0023] The content of the present application will be further described in detail below in combination with specific embodiments:

[0024] As Figure 1 and Figure 2 shown, a product assembly positioning auxiliary device is used to fix the spatial position of the plurality of pins 13 of the product 1, so that they can simultaneously penetrate the plurality of through holes on the locking sheet 11, and realize the assembly of the locking sheet 11 and the body 12. The present application comprises a base plate 2 and a positioning clamp. Among them, the product 1 is carried on the base plate 2. The positioning clamp has an upper clamping jaw 3 and a lower clamping jaw 4, as Figure 3 shown, the upper clamping jaw 3 and the lower clamping jaw 4 are driven by the clamping driver 5 to synchronously open and close relative to the product 1.

[0025] The upper clamping jaw 3 is provided with a plurality of clamping teeth 31, and the lower clamping jaw 4 is provided with a clamping groove 41 matched with the clamping teeth 31, and the clamping teeth 31 and the clamping groove 41 cooperate to form a clamping space for the pins 13. Corresponding to the matrix form of the pins 13, the clamping teeth 31 are provided with long clamping teeth 31 and short clamping teeth 31, and the clamping groove 41 has long clamping grooves 41 and short clamping grooves 41 correspondingly. Under the action of the clamping driver 5, the long clamping teeth 31 and the long clamping grooves 41, the short clamping teeth 31 and the short clamping grooves 41 cooperate with each other to clamp any pin 13, so that the pin 13 is in a preset spatial position, thereby avoiding that the pin 13 cannot be assembled with the locking sheet 11 due to skew.

[0026] Specifically, the clamping driver 5 adopts an electric cylinder, and the clamping driver 5 is connected with the upper clamping jaw 3 and the lower clamping jaw 4 through a connecting rod mechanism 6. The connecting rod mechanism 6 includes a first connecting rod 61 and a second connecting rod 62, the first connecting rod 61 is hinged with the execution end of the clamping driver 5, one end of the second connecting rod 62 is hinged with the first connecting rod 61, the other end is slidingly abutted with the upper clamping jaw 3 or the lower clamping jaw 4, and the middle part of the second connecting rod 62 is hinged with the base plate 2. Moreover, a guide is fixed on the base plate 2, the guide is arranged parallel to the movement plane of the connecting rod mechanism 6, and the upper clamping jaw 3 and the lower clamping jaw 4 are slidingly matched with the guide. In this way, through the extension and retraction movement of the execution end of the clamping driver 5, the clamping action of the upper clamping jaw 3 and the lower clamping jaw 4 can be realized.

[0027] In addition, in combination with Figure 1 and Figure 2As shown, the second connecting rod 62 is fixed with a roller 63 at one end away from the first connecting rod 61, and the upper clamping jaw 3 and the lower clamping jaw 4 are provided with a sliding groove corresponding to the roller 63, and the roller 63 is slidingly arranged in the sliding groove.
