[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 As shown, this utility model is a test template positioning fixture, specifically capable of positioning and clamping according to the actual size of the car door panel, including a positioning frame 1; a reciprocating screw 3 is installed on the inner side of the positioning frame 1, and an active connecting block 4 for tilt adjustment of the active support rod 5 is provided on the outer side of the upper end of the reciprocating screw 3, and a limiting bracket 6 that moves laterally within the positioning frame 1 through a fixed limiting rod 8 is provided on the upper end of the active support rod 5.

[0027] In this embodiment, preferably, the reciprocating lead screw 3 and the movable connecting block 4 are connected by a thread. The outer end of the movable connecting block 4 is provided with a symmetrical vertical protrusion that is connected to the movable support rod 5. When the reciprocating lead screw 3 is rotated, the movable connecting block 4, which is threaded to the reciprocating lead screw 3, can move up and down.

[0028] In this embodiment, preferably, the movable connecting block 4 and the limiting bracket 6 both form a rotating structure with the movable support rod 5. The limiting bracket 6 forms a locking sliding structure inside the positioning frame 1 through the fixed limiting rod 8, which can make the limiting bracket 6 more stable when it moves laterally as a whole.

[0029] In this embodiment, preferably, a clamping block 9 is fixedly installed on the upper end of the limiting bracket 6, a positioning block 901 is provided on the lower inner side of the clamping block 9, and a rubber buffer pad 902 with a buffering effect is provided on the inner edge of the clamping block 9. During the positioning and clamping process, the edge of the car door panel can be protected by the rubber buffer pad 902 to avoid deformation and damage caused by excessive clamping force.

[0030] In this embodiment, preferably, a movable guide block 903 is provided directly above the positioning block 901, and a guide post 904 penetrating through the clamping block 9 is provided at the upper middle part of the movable guide block 903. A damping spring 905 located between the movable guide block 903 and the clamping block 9 is provided on the outer side of the guide post 904, which can center and limit the damping spring 905 under the action of the guide post 904.

[0031] In this embodiment, preferably, the movable guide block 903 and the guide post 904 are vertically fixedly connected. The movable guide block 903 forms an elastic telescopic structure on the upper side inside the clamping block 9 through the damping spring 905, which can adaptively adjust according to the actual thickness of the car door panel.

[0032] In summary, after the positioning frame 1 is fixedly installed in the designated position and a certain cavity is left for the servo motor 2 to avoid compression, the car door panel that needs to be positioned and clamped is placed on the upper surface of the positioning support column 10. The reciprocating screw 3 and the movable connecting block 4 are connected by threads. When the servo motor 2 is turned on and the reciprocating screw 3 is rotated, the threaded movable connecting block 4 can be driven to move up and down in the positioning frame 1. The movable connecting block 4 and the limiting bracket 6 both form a rotating structure on the movable support rod 5. At this time, when the movable connecting block 4 moves up and down, it can drive the movable support rod 5 to move in an inclined manner, so as to drive the limiting bracket 6 to move laterally in a nested manner on the fixed limiting rod 8 through the through groove 7, so that the limiting bracket 6 can slide in a locking manner in the clearance groove opened inside the positioning frame 1, thereby improving the stability of the lateral movement of the limiting bracket 6 and avoiding shaking.

[0033] Furthermore, when the limiting bracket 6, which is arranged in four equal parts around the center point of the positioning frame 1, moves inward, the clamping block 9 fixedly installed on the upper end of the limiting bracket 6 can move synchronously. As the limiting bracket 6 moves inward, the edge of the car door panel can enter the inner side of the clamping block 9 through the positioning block 901, and the edge of the car door panel is connected to the rubber buffer pad 902. This allows the edge of the car door panel to be protected by the rubber buffer pad 902, preventing damage to the car door panel during subsequent operations. The positioning block 901 and the movable guide block 903 are arranged vertically and vertically, and both of their longitudinal sections are inclined to the left, which can guide and clamp the car door panel. Since the movable guide block 903 forms an elastic telescopic movement on the upper side of the clamping block 9 through the damping spring 905, it can be adjusted according to the actual thickness of the car door panel, thereby positioning and clamping the car door panel. The movable guide block 903 can also perform stable lifting and lowering movement under the action of the guide column 904, and can center the damping spring 905 to avoid shaking.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 and Figure 3 The image shows the second embodiment of this utility model, which is capable of assisting in pushing operations so that it can be operated and used in emergency situations. It includes a mounting bracket 11 fixedly installed on the outer side of the upper end of the positioning frame 1, and a telescopic rod 13 connected to the fixed limiting rod 8 is provided at the inner end of the mounting bracket 11.

[0036] In this embodiment, preferably, the limiting bracket 6 is arranged in four equal parts about the center point of the positioning frame 1. The limiting bracket 6 is connected to the telescopic rod 13 by means of threads through the adjusting bolt 14, which enables a stable connection and installation between the limiting bracket 6 and the telescopic rod 13.

[0037] In this embodiment, preferably, the telescopic rod 13 is located at the inner end of the mounting frame 11 and connected to the cylinder 12, so that when the cylinder 12 is driven, the limiting bracket 6 can move laterally within the positioning frame 1.

[0038] In summary, when rust or other faults occur at the connection between the reciprocating screw 3 and the movable connecting block 4, and at the connection between the movable connecting block 4 and the movable support rod 5 and the limiting bracket 6, the cylinder 12 installed at the outer end of the mounting bracket 11 can be opened. When the telescopic rod 13 is driven, the limiting bracket 6, which is threadedly connected by the adjusting bolt 14, is moved inward, thereby providing emergency auxiliary movement, positioning, and clamping for the car door panel. This can be done in emergency situations to avoid affecting the positioning and clamping effect.
