Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooling fixtures, and more specifically to a tooling for installing and positioning a front door of an automobile. Background Art
[0002] The auxiliary lifting device for installing the front and rear doors used in automobile processing is a tool for assembling automobiles. Currently, the tools for installing and suspending automobile doors are mostly installed by bundling with ropes or by clamping. When fixing the door to the car body, the clamping method is not convenient enough, and the rope lifting is usually not stable enough, which easily affects the installation efficiency.
[0003] Patent authorization number CN218809795U discloses an auxiliary lifting device for front and rear door installation used in automobile processing. Patent authorization number CN205257811U can adsorb the car door through the suction cup, so as to lift the car door. The anti-slip pad and clamping groove can assist the clamping plate to clamp the car door to realize the clamping function of the lifting device. The electric roller and roller can realize the continuous movement of the lifting device when the lifting fixed frame falls to the ground, which is more flexible to use.
[0004] However, the lifting and fixing frame in patent authorization number CN205257811U is a two-section adjustable mechanism, the first pneumatic telescopic rod is fixed at the upper and lower ends of both sides of the lifting and fixing frame, the connecting plate is located on the side where the first curved rod is located, and the suction cup is away from the lifting and fixing frame and the clamping plate. The suction cup can adsorb the car door, thereby enabling the door to be lifted. Since the car door is hoisted and installed, the positioning of the car door is inaccurate during the installation process, and the staff is required to repeatedly adjust the door during the installation process, thereby affecting the installation efficiency. Therefore, we proposed a car front door installation positioning tooling to solve the above-mentioned problems. Utility Model Content
[0005] 1. Technical issues to be solved
[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a car front door installation positioning tool, which can use a turning handle to drive the positioning pin so that the matching insertion rod is screwed in and connected with the pin hole until the front door body and the rubber pad are tightly fitted, and then the front door body is pushed to make the dovetail slider slide in conjunction with the dovetail slide groove, thereby positioning the front door body at the front door installation position of the car, eliminating the need for repeated adjustments during the installation process, thereby improving the installation efficiency of the front door body.
[0007] 2. Technical solution
[0008] To solve the above problems, the utility model adopts the following technical solutions.

Symmetrically and fixedly connected to the top of the connecting beam are brackets, and jacks are opened at the ends of the bent parts at the tops of the brackets;
[0011] A rubber cushion block that abuts against the front door body is installed on the outer wall of the bracket;
[0012] A plug rod is detachably connected to the jack, and a limiting block that abuts against the top opening of the jack is integrally formed at the top end of the plug rod;
[0013] A positioning pin that is inserted and connected to the pin hole is installed at the bottom end of the plug rod, and a turning handle is installed at one end of the positioning pin away from the front door body.
[0014] Furthermore, connecting frames are welded to both ends of the connecting beam, and rollers are symmetrically installed at the bottom of the connecting frames.
[0015] Furthermore, fixed ears are symmetrically and fixedly connected to the outer walls on both sides of the slide rail, and mounting holes are opened on the surfaces of the fixed ears.
[0016] Furthermore, the jack and the plug rod are in clearance fit.
[0017] Furthermore, the outer diameter of the positioning pin is adapted to the inner diameter of the pin hole.
[0018] Furthermore, threads that are screwed to the plug rod are opened on the outer wall of the positioning pin, and one end of the positioning pin that is inserted into the pin hole is provided with a smooth surface structure.
[0019] Furthermore, one end of the positioning pin away from the turning handle is provided with a conical surface structure.
[0020] 3. Beneficial effects
[0021] Compared with the prior art, the advantages of the present utility model are as follows:
[0022] (1) In this solution, the installation position of the slide rail corresponds to the installation position of the front door of the car. After the front door body is hoisted, the window of the front door body is passed through the bent end of the top of the bracket, and then the plug rod is inserted into the inner side of the hole, and a positioning pin is installed at the bottom end of the plug rod. The positioning pin is then driven by a turning handle to make it rotate in conjunction with the plug rod and engage with the pin hole until the front door body and the rubber pad are tightly fitted. The front door body is then pushed to make the dovetail slider slide in conjunction with the dovetail slide groove, thereby positioning the front door body at the installation position of the front door of the car. There is no need for repeated adjustments during the installation process, thereby improving the installation efficiency of the front door body.
[0023] (2) In this solution, the dovetail slider cooperates with the dovetail groove to slide, and the rollers provided at the bottom of the connecting frame cooperate with the contact surface to roll, thereby effectively increasing the span of the connecting beam, thereby ensuring the stability of the front door body during movement.
