[0002] Automotive door panels are retractable panels mounted on the side of a car body, allowing passengers to enter and exit the vehicle. The production process for automotive door panels involves multiple steps, including stamping, welding, gluing, and pressing. First, steel sheets and other materials are stamped into shape to create the outer and inner door panels. The inner panel is then welded to components such as the window frame. Glue is then applied between the inner and outer panels and pressed together to ensure the door's tightness and strength.

[0003] In the existing technology, after the automobile door panels are produced, they will be tested to ensure the product's qualification rate and facilitate subsequent assembly. During the test, the door panels are fixed by a jig positioning mechanism. The jig is also called a fixture. The design of the jig takes into account factors such as the shape, size and weight of the automobile door panels to ensure that it can fit the door panels tightly and provide sufficient support force, thereby better clamping and positioning them.

[0004] However, in the aforementioned prior art, the jig positioning mechanism in the current testing device can only test one type of door panel. When multiple door panels need to be tested, multiple devices need to be used, which wastes testing time and increases testing costs. Utility Model Content

[0021] According to this specific embodiment, the workpiece is placed on the workbench 101, and then clamped and positioned by the corresponding jig body 111. Each jig body 111 has a different inner cavity shape, so as to match the corresponding door panel shape for easy positioning. When it is necessary to replace the jig body 111 with a different inner cavity shape, the limit rod 108 is pulled to disengage the limit rod 108 from the corresponding limit hole 120, and then the first slider 110 is pulled to move, thereby adjusting the position of the corresponding jig body 111 so that the corresponding jig body 111 is in the same horizontal position as the workpiece, and then the limit rod 108 is released, and under the elastic force of the spring, it is adapted to the corresponding limit hole 120 again, thereby limiting and fixing the first slider 110. In this way, the device can perform positioning work of multiple door panels on the same equipment by adjusting different jig bodies 111, thereby reducing the cost and time of testing.

[0022] In which, the movable unit is arranged on the workbench 101, the buffer unit is arranged on the movable unit, the first guide rail 109 is arranged on the buffer unit, the first slider 110 is slidably adapted to the first guide rail 109, the shell 105 is fixedly connected to the side of the first guide rail 109, one end of the limiting rod 108 passes through the shell 105 and the first guide rail 109, and is adapted to the corresponding limiting hole 120, a plurality of the mold bodies 111 are respectively arranged on the first slider 110, the ring 107 is fixedly sleeved on the outside of the limiting rod 108, and is located inside the shell 105, and the two ends of the spring are respectively fixedly connected to the inner side wall of the shell 105 and the ring 107. The workpiece is placed on the workbench 101 and then clamped and positioned by the corresponding jig body 111. Each jig body 111 has a different inner cavity shape, so as to match the corresponding door panel shape for easy positioning. When it is necessary to replace the jig body 111 with a different inner cavity shape, the limit rod 108 is pulled to disengage the limit rod 108 from the corresponding limit hole 120, and then the first slider 110 is pulled to move, thereby adjusting the position of the corresponding jig body 111 so that the corresponding jig body 111 is in the same horizontal position as the workpiece, and then the limit rod 108 is released. Under the elastic force of the spring, it is adapted to the corresponding limit hole 120 again, and then the first slider 110 is limited and fixed. In this way, the device can perform positioning work of multiple door panels on the same equipment by adjusting different jig bodies 111, thereby reducing the cost and time of testing.

[0023] Next, the second guide rail 113 is fixedly connected to the upper end of the workbench 101, the second slider 114 is slidably adapted to the second guide rail 113, the cylinder 112 is disposed inside the second guide rail 113, and the output end of the cylinder 112 is fixedly connected to the second slider 114.

The second slider 114 is pushed to move in the second guide rail 113 through the output end of the cylinder 112, thereby driving the fixed plate 115 to move, so that the corresponding jig body 111 and the workpiece are clamped and positioned. When the jig body 111 is clamped, the elastic force of the second spring 118 is applied to make the jig body 111 have a certain buffer stroke, thereby reducing damage to the workpiece during clamping. When the second spring 118 rebounds, the multiple slide rods 117 slide in the corresponding cylinder 116 and play a supporting role on the first guide rail 109.

[0024] At the same time, the pull handle 102 is fixedly connected to the first slider 110 and is located at the upper end of the first slider 110. The setting of the pull handle 102 makes it easier for the staff to pull the first slider 110 to move within the first guide rail 109, thereby improving convenience.

[0025] Furthermore, the plurality of support legs 103 are respectively fixedly connected to the workbench 101 and are located around the bottom of the workbench 101.

Under the elastic force of the spring, it is adapted to the corresponding limiting hole 120 again, and then the first slider 110 is limited and fixed. In this way, the device can perform positioning work of multiple door panels on the same equipment by adjusting different jig bodies 111, thereby reducing the cost of testing. The testing time is reduced. The output end of the cylinder 112 pushes the second slider 114 to move in the second guide rail 113, thereby driving the fixed plate 115 to move, so that the corresponding jig body 111 and the workpiece are clamped and positioned. When the jig body 111 is clamped, the elastic force of the second spring 118 makes the jig body 111 have a certain buffer stroke, thereby reducing damage to the workpiece during clamping. When the second spring 118 rebounds, the multiple sliding rods 117 slide in the corresponding cylinder 116 and play a supporting effect on the first guide rail 109.
