[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0036] See Figures 1-6 A clamping mechanism for positioning assembly components includes a base 1 for placing assembly component 2, wherein the base 1 is provided with an X-axis positioning component 3 and / or a Z-axis positioning component 4 and / or a Y-axis positioning component 5 for clamping assembly component 2.

[0037] The X-axis positioning component 3 positions the assembled component 2 on the base 1 along the X-axis.

[0038] The Z-axis positioning component 4 positions the assembled component 2 on the base 1 along the Z-axis.

[0039] The Y-axis positioning component 5 positions the assembled component 2 on the base 1 along the Y-axis.

[0040] The base 1 is provided with a first side plate 6 and a second side plate 7, which are used to position the X-axis and are arranged opposite to each other.

[0041] The X-axis positioning assembly 3 is provided with an adjusting member 8 for adjusting the front and rear position of the X-axis positioning assembly 3 in the X-axis direction of the base 1, and the X-axis positioning assembly 3 moves back and forth along the first side plate 6 and the second side plate 7 when it is adjusted.

[0042] In this embodiment, the adjusting member 8 is an adjusting screw. When the adjusting screw is loosened, the X-axis positioning component 3 can be pushed on the X-axis of the base 1.

[0043] The base 1 is provided with a first mounting plate 9 and a second mounting plate 10 for mounting the Z-axis positioning component 4. The first mounting plate 9 and the second mounting plate 10 are arranged opposite to each other. The Z-axis positioning component 4 is detachably mounted on the first mounting plate 9 and the second mounting plate 10, so that the Z-axis positioning component 4 can be arbitrarily mounted on one of the mounting plates.

[0044] The first mounting plate 9 and the second mounting plate 10 are arranged opposite each other, and the Z-axis positioning component 4 can be installed arbitrarily to avoid interference of clamping movement.

[0045] In this embodiment, one end of the X-axis positioning component 3 reciprocates along the X-axis direction of the base 1 to the position of releasing and clamping the assembly component 2. When one end of the X-axis positioning component 3 moves axially toward the position of releasing the assembly component 2, the assembly component 2 is released on the base 1. When one end of the X-axis positioning component 3 moves axially toward the position of clamping the assembly component 2, the assembly component 2 is clamped on the base 1, thus restricting the degree of freedom of the assembly component 2 in the X-axis direction of the base 1.

[0046] The clamping mechanism for positioning the assembly components also includes a third side plate 11 and a fourth side plate 12 for positioning the X-axis and arranged opposite to each other.

[0047] The X-axis positioning assembly 3 includes a slider 13 that reciprocates along the X-axis of the base 1. The base 1 is provided with a first pressing block 14 for pressing one side of the slider 13 and a second pressing block 15 for pressing the other side of the slider 13.

[0048] The first pressing block 14 is limited on the inner side of the third side plate 11, and the second pressing block 15 is limited on the inner side of the fourth side plate 12;

[0049] The slider 13 is limited in the upper and lower parts on one side between the base 1 and the first pressure block 14, and the slider 13 is limited in the upper and lower parts on the other side between the base 1 and the second pressure block 15;

[0050] In this embodiment, the first pressure block 14 and the second pressure block 15 are respectively fixed to the base 1 by screws.

[0051] A motion guide groove for slider 13 is formed between the first pressure block 14 and the second pressure block 15. Slider 13 reciprocates along the motion guide groove on the X-axis of base 1.

[0052] The Y-axis positioning component 5 includes a first plastic positioning block 18 and a second plastic positioning block 19 arranged opposite each other. The first plastic positioning block 18 and the second plastic positioning block 19 act on the side of the assembly component 2 to ensure that the assembly component 2 and the X-axis positioning component 3 are on the same axis.

[0053] In this embodiment, the first plastic positioning block 18 and the second plastic positioning block 19 are respectively fixed to the base 1 by screws.

[0054] The X-axis positioning assembly 3 includes a slider 13 that reciprocates along the X-axis of the base 1, and a first cylinder 20 for driving the slider 13 to move. The piston rod of the first cylinder 20 is connected to the slider 13 in a transmission manner.

[0055] In this embodiment, the cylinder body of the first cylinder 20 is fixed to the base 1 by adjusting screws.

[0056] The Z-axis positioning assembly 4 includes a Z-axis positioning block 21 and a second cylinder 22 for driving the Z-axis positioning block 21 to rotate circumferentially and / or move vertically; the piston rod of the second cylinder 22 is connected to the Z-axis positioning block 21 in a transmission connection.

[0057] The second cylinder 22 is a rotary clamping cylinder, also known as a corner cylinder.

[0058] In this embodiment, the second cylinder 22 is detachably mounted on the first mounting plate 9 and the second mounting plate 10 by screws.

[0059] The base 1 is provided with a pneumatic regulator 23 for adjusting the pneumatic drive value of the first cylinder 20 and / or the second cylinder 22.

[0060] In this embodiment, one end of each cylinder body is connected to an air pipe, and the air pipe is connected to an air pressure regulator 23. The air pressure regulator 23 is an air pressure regulating valve to prevent excessive pressure from damaging the product and injuring the hands.

[0061] The base 1 is equipped with a first switch 24 and a second switch 25. The first switch 24 and the second switch 25 are operated simultaneously to trigger the operation of the Z-axis positioning assembly 4 and the X-axis positioning assembly 3 of the two mounting seats. Each cylinder is equipped with an airflow valve to adjust the movement sequence.

[0062] Both the first switch 24 and the second switch 25 must be pressed simultaneously for both second cylinders 22 to activate, preventing accidental hand injury. This can be understood as the first switch 24 and the second switch 25 being connected in series; pressing only one switch will not trigger the operation of either second cylinder 22 or the first cylinder 20.

[0063] The first switch 24 and the second switch 25 are push-button switches.

[0064] The piston rod of the second cylinder 22 is provided with a connecting arm 29, and the connecting arm 29 is provided with an adjusting screw 26 connected to the Z-axis positioning block 21. The adjusting screw 26 is provided with a locking element 27. The piston rod of the second cylinder 22 drives the Z-axis positioning block 21 to move through the connecting arm 29. The adjusting screw 26 is inserted through the connecting arm 29 and connected to the Z-axis positioning block 21. The adjusting screw 26 rotates on the connecting arm 29 and drives the Z-axis positioning block 21 to move up and down to adjust the vertical position of the Z-axis positioning block 21 on the connecting arm 29.

[0065] The bottom of the Z-axis positioning block 21 is provided with a flexible part 28 for preventing wear on the assembled components.

[0066] When the flexible part 28 comes into frictional contact with the outer surface of the assembly component 2 during the swinging process of the Z-axis positioning block 21, it can avoid serious wear on the outer surface of the assembly component 2, effectively protect the appearance of the assembly component 2, and thus ensure the original machining accuracy of the assembly component 2.

[0067] In this embodiment, the locking member 27 is a locking nut. When the locking nut is loosened, the adjusting screw 26 can be rotated by a tool. The connecting arm 29 is provided with a threaded inner cavity for inserting the adjusting screw 26. When the adjusting screw 26 rotates, it drives the Z-axis positioning block 21 to move up and down through the internal and external thread transmission structure. The adjusting screw 26 rotates counterclockwise or clockwise, thereby driving the Z-axis positioning block 21 to move up or down. This can accommodate assembly components 2 of different thicknesses.

[0068] The first pressing block 14 is provided with a first step portion 16 forming a first limiting groove between itself and the base 1; the second pressing block 15 is provided with a second step portion 17 forming a second limiting groove between itself and the base 1;

[0069] The slider 13 is limited in the upper and lower parts on one side in the first limiting groove, and the slider 13 is limited in the upper and lower parts on the other side in the second limiting groove to prevent the slider 13 from moving up and down.

[0070] The slider 13 has a first pressure strip on one side that cooperates with the first step portion 16, and a second pressure strip on the other side that cooperates with the second step portion 17.

[0071] In this embodiment, the base 1 is provided with a positioning end at one end corresponding to the reciprocating motion direction of the slider 13. When the slider 13 moves close to the positioning end, it performs a clamping action, and when the slider 13 moves away from the positioning end, it performs a releasing action.
