Description

Technical Field

[0001] The utility model relates to the technical field of closing tooling, in particular to a closing tooling for a promotional vehicle body. Background Art

[0002] The propaganda vehicle is a multimedia mobile advertising studio vehicle. Through the color screens on both sides, it can play various video advertisements in a loop. When processing the carriage of the propaganda vehicle, it is necessary to use a closing tool. The closing tool can facilitate the fixing and docking of the side panel frames of the carriage, and then facilitate the assembly and welding of the entire carriage.

[0003] Existing closing tooling is generally assembled and fixed from the front and rear panels and left and right side panels of the vehicle body, and then welded. During welding, high temperatures are generated. Since the degree of shrinkage and deformation of the panels on each side of the vehicle body cannot be kept the same, the frame will be heated and deformed during the welding process, affecting the normal processing of the vehicle body. Utility Model Content

[0006] As an optimization, the optical axis slide rails are arranged in pairs in a group of two, with two groups located in the middle and two groups arranged vertically on both sides of the group.

[0007] As an optimization, the specifications of the square tube one are 80*60*1000, and the specifications of the square tube two are 80*60*2000.

[0008] As an optimization, the positioning clamping assembly is slidably connected to a movable slider inside the slide groove, and a connecting plate is fixedly installed on the side of the movable slider located outside the slide groove, and a translation plate is provided on the side of the connecting plate away from the movable slider. A threaded hole is opened inside one side of the movable slider, and a screw is threadedly connected to the threaded hole. A guide rod is fixedly installed on the surface of one side of the movable slider, a turning handle is fixedly installed on the end of the screw, and a baffle is fixedly installed on the outside of the end of the screw close to the turning handle.

[0009] As an optimization, the screw rod passes through the translation plate, and the baffle plate rotates and abuts against the outer surface of the translation plate. By turning the handle, the screw rod will be driven to rotate in the threaded hole, and then the baffle plate will be squeezed to approach the movable slider, so that the translation plate will clamp the car frame.

[0010] As an optimization, a guide hole is opened at the guide rod corresponding to the translation plate, and the guide rod is slidably inserted in the guide hole. The guide rod limits the translation plate, so that the translation plate slides along the outside of the guide rod to ensure the stability of the car body support and fixation.

[0011] As an optimization, a buffer spring is sleeved on the outer side of the screw, and the buffer spring is fixedly installed between the connecting plate and the translation plate. A pressure plate is fixedly installed on the end of the translation plate. The pressure plate can increase the contact area of ​​the clamping car frame, thereby further improving stability. The buffer spring is compressed during clamping, which can appropriately buffer the clamping force and avoid damage to the car frame due to overpressure.

[0012] As an optimization, a rubber pad is provided on the side of the pressure plate that contacts the car frame. The rubber pad is in direct contact with the car frame to avoid scratching and damaging the car surface.

[0013] The beneficial effects of the utility model are:

[0014] 1. The promotional car body closing tooling, through the left tooling operating table, front and rear tooling operating tables and tooling frame welded on the square tube and kept perpendicular to the base, can make the left tooling operating table and the front and rear tooling operating tables on both sides move forward and backward along the track of the optical axis slide rail, thereby facilitating the placement and closing of the car body frame and the removal of the tooling after the closing welding is completed. The single-sided movable tooling design provides great convenience for the removal of the car body after welding is completed, and can also avoid the interference of parts caused by thermal deformation of the frame during welding, excessive deformation of the clamp force, etc. to the greatest extent.

[0015] 2. The promotional car body closing tool pushes the movable slider to slide along the inner wall of the slide groove close to the edge of the car frame, and then turns the handle to make the screw rotate in the threaded hole, which will drive the translation plate away from the connecting plate, and then turn the handle in the opposite direction. By the same token, it can drive the pressure plate close to the clamping car frame, which will play a role in clamping and positioning the car frame, which is convenient and quick.
