The first guide groove 6, the guide protrusion 7 and the second guide groove 8 are arranged in sequence from top to bottom on the guide plate 5. The first guide groove 6, the guide protrusion 7 and the second guide groove 8 are all arranged along the left-right direction. Among them, the first guide groove 6 and the second guide groove 8 are both provided with sinking grooves in the left-right direction, and the sinking grooves of the two are staggered. The guide protrusion 7 is a structural setting in which the middle is convex toward the inside and the two sides are concave toward the outside.

[0035] like Figure 3 and Figure 4 The positioning tool 3 includes a tool base plate 9, a rotating shell 18, a support mounting seat 20, a large surface clamping block 22 and a side clamping block 24. The bottom of the tool base plate 9 is installed on the conveying line 1 below through a conveying linkage mechanism 10. The support mounting seat 20 is used to install a square product 21. The large surface clamping blocks 22 are rotatably installed on both the front and rear sides of the support mounting seat 20, and the side clamping blocks 24 are rotatably installed on both the left and right sides of the support mounting seat 20. The bottom of the square product 21 is placed on the support mounting seat 20. The two large surface clamping blocks 22 are used to clamp the large surfaces on the front and rear sides of the square product 21, and the two side clamping blocks 24 are used to clamp the sides on the left and right sides of the square product 21.

[0036] The rotating structure of the support mounting seat 20:

[0037] A rack 11 that can slide in the front-to-back direction is installed on the tooling base plate 9. The rack 11 is meshed with a gear 17 installed on the left side of the rotating shell 18. The bottom of the rotating shell 18 is installed on the tooling base plate 9 through a bearing 16. The rotating ejector pin 12 at the front end of the rack 11 is adapted to the guide protrusion 7.

[0038] A rack stopper 29 is installed on the tooling base plate 9 at the rear end of the rack 11, and a rack spring 30 is installed between the rack 11 and the rack stopper 29. The bottom of the rack 11 is connected to a guide rail 32 distributed along the front and rear direction and installed on the tooling base plate 9 through a slider 31.

[0039] The opening and closing structure of the large surface clamping block 22:

[0040] The bottom of the pull rod 14 installed in the rotating housing 18 passes through the tooling bottom plate 9 and is connected to the first handle 13. Two first cam followers 15 adapted to the second guide grooves 8 are installed on the first handle 13. The top two sides of the pull rod 14 are respectively connected to the upper large surface clamping block 22 through the first mechanical arm 19. The large surface clamping block 22 is rotatably installed on the support mounting seat 20 through the first rotating rod 23 distributed along the left and right directions, and is connected to the pull rod spring installed in the rotating housing 18 at the top of the pull rod 14.

[0041] The opening and closing structure of the side clamping block 24:

[0042] The bottom of the side clamping block 24 is connected to the second handle 27 below through the second mechanical arm 26, and a second cam follower 28 adapted to the first guide groove 6 is installed on the outer side of the second handle 27. The side clamping block 24 is rotatably mounted on the support mounting seat 20 through a second rotating rod 25 distributed along the front-to-back direction.

[0043] In addition, a limit frame is installed at the upper left corner of the tooling bottom plate 9, and a limit stop column is installed on the top of the limit frame. The rotation angle of the support mounting seat 20 can be limited by the limit stop column.

[0044] The working process of the present invention is briefly described as follows:

[0045] During the movement of the positioning fixture 3 of the present invention, the three track grooves (the first guide groove 6, the guide protrusion 7, and the second guide groove 8) on the guide plate 5 realize the rotation of the square product fixture and the opening and closing of the clamp in two directions.

[0046] The rotating ejector pin 12 on the rack 11 is adapted to the guide protrusion 7 on the guide plate 5. During the movement of the tooling base plate 9, the rotating ejector pin 12 contacts the trajectory of the outer guide protrusion 7, thereby realizing the forward and backward movement of the rack 11 and driving the upper support mounting seat 20 to rotate through the gear 17 and the rotating shell 18.

[0047] The first cam follower 15 on the first handle 13 cooperates with the trajectory of the second guide groove 8, thereby driving the pull rod 14 to move up and down. The pull rod 14 drives the upper large-surface clamping block 22 to rotate through the first mechanical arm 19, thereby realizing the opening and closing of the large-surface clamping block 22.

[0048] The second cam follower 28 on the second handle 27 cooperates with the trajectory of the first guide groove 6, thereby driving the second handle 27 to move up and down. The second handle 27 drives the upper side clamping block 24 to rotate through the second mechanical arm 26, thereby realizing the opening and closing of the side clamping block 24.

[0049] The left-right direction, front-back direction, and up-down direction shown in this article are all based on Figure 2 and Figure 3 The status in shall prevail.

[0050] The present invention performs five-sided precise machining during the uniform speed movement process, and the product positioning fixture can realize opening and closing of the clamp in different ways during the movement process, which greatly shortens the switching time of the auxiliary mechanism, improves the utilization rate of the finishing equipment, reduces the cost of the entire machine, and reduces the space occupied by the machine.
