Description
Technical Field
[0001] The utility model belongs to the technical field of press-fitting fixtures, and in particular relates to a press-fitting fixture for an inner guard plate of an automobile door. Background Art
[0002] At present, when pressing the inner door guard plates of automobiles, most of them are pressed manually. The operator needs to place the inner door guard plates of automobiles on the pressing fixture one by one, and press down the inner door guard plates of automobiles through a hydraulic press to complete the pressing after the two inner door guard plates of automobiles are fitted and fixed. However, the pressing fixture currently used cannot effectively protect the inner door guard plates of automobiles. If the positions of the inner door guard plates of automobiles are not aligned, it is very easy to cause the inner door guard plates of automobiles to be squeezed and deformed against each other when pressing down, thereby causing material loss. Therefore, a pressing fixture for inner door guard plates of automobiles is designed to solve the problem that the current pressing fixture cannot effectively protect the inner door guard plates of automobiles from being squeezed and deformed. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1 and Figure 3 As shown, the utility model provides the following technical solutions: a press-fitting fixture for an inner guard plate of an automobile door comprises a base 8, a hydraulic cylinder 10, a lifting plate 7 and a fixing assembly, the hydraulic cylinders 10 are symmetrically installed on both sides of the inner wall of the base 8, the ends of the hydraulic cylinders 10 extend to the outside of the base 8, and the ends of the hydraulic cylinders 10 are connected to the lifting plate 7, a fixing assembly is arranged inside the lifting plate 7, the fixing assembly is used for the fixed connection between the inner guard plate of the door and the lifting plate 7, the fixing assembly comprises an inner guard plate mold 1, an engaging groove 4 and an electromagnet 6, and an engaging groove is provided in the middle of the front end surface of the lifting plate 7 4, the fitting groove 4 is a T-shaped groove, and a door inner guard plate mold 1 is arranged in the fitting groove 4, electromagnets 6 are symmetrically installed on both sides of the top of the inner wall of the fitting groove 4, and the end faces of the electromagnets 6 are flush with the inner wall of the fitting groove 4, and guide holes 13 are symmetrically opened on the surface of the base 8 and located between the hydraulic cylinders 10, and a guide rod 9 is arranged in the guide hole 13, and a placement plate 3 is connected to the end of the guide rod 9, and the placement plate 3 is located below the door inner guard plate mold 1, and a spring 5 is arranged at the bottom of the placement plate 3 and outside the guide rod 9, and the bottom of the spring 5 is in contact with the bottom of the guide hole 13.
[0019] Through the above technical solution: when in use, the operator first embeds the car door inner guard plate mold 1 into the fitting groove 4, and places the car door inner guard plate on the placement plate 3, and then presses down the lifting plate 7 through the hydraulic cylinder 10, and uses the electromagnet 6 to adsorb the car door inner guard plate on the car door inner guard plate mold 1, resets it and places another car door inner guard plate on the placement plate 3, and restarts the hydraulic cylinder 10 to press down after the alignment is completed. After the lifting plate 7 contacts the placement plate 3, the hydraulic cylinder 10 continues to squeeze the placement plate 3 downward, forcing the placement plate 3 to move down and squeeze the spring 5, gradually shortening the distance between the placement plate 3 and the base 8, and utilizing the rebound force of the spring 5 and the downward pressure of the hydraulic cylinder 10. , the two automobile door inner guard plates are embedded and fixed, and the elastic force of the spring 5 is used to reduce the direct pressure on the lower automobile door inner guard plate. At the same time, since the lower automobile door inner guard plate itself is not directly placed on the base 8, if the position is offset, the lower automobile door inner guard plate will not be deformed in the first time, and sufficient time is reserved for production personnel to shut down the equipment in time, thereby reducing material loss and solving the problem that the current press-fitting fixture cannot effectively protect the automobile door inner guard plate from extrusion deformation. In addition, the embedded connection between the guide rod 9 and the guide hole 13 is used to guide the moving direction of the placement plate 3, thereby reducing the displacement of the placement plate 3 itself, which causes the two automobile door inner guard plates to be offset.
[0020] See also Figure 1-Figure 2 As shown, the width of the door inner guard plate mold 1 is smaller than the width of the lifting plate 7, and a positioning hole 12 is symmetrically opened on the surface of the lifting plate 7 and located at the front end of the fitting groove 4. A latch 11 is penetrated through the positioning hole 12, and the end of the latch 11 extends into the fitting groove 4. An auxiliary ring is installed on the top of the lifting plate 7 and located on the periphery of the positioning hole 12. The diameter of the auxiliary ring is smaller than the end face diameter of the latch 11, and an anti-slip strip is installed on the inner wall of the auxiliary ring. The anti-slip strip is in contact with the outer wall of the latch 11, and a rubber layer 2 is provided on the top of the placement plate 3, and the rubber layer 2 is in contact with the door inner guard plate mold 1.
[0021] Through the above technical scheme: before press-fitting, the door inner guard plate mold 1 is embedded into the fitting groove 4, and then the pin 11 is embedded into the positioning hole 12, and the fitting groove 4 is closed by the pin 11 to block the movement of the door inner guard plate mold 1, so as to prevent the movement of the door inner guard plate mold 1 during production, causing the two car door inner guard plates to be misaligned. The setting of the auxiliary ring ensures that there is always a gap between the pin 11 and the lifting plate 7 to facilitate the operator to pull out the pin 11. At the same time, the anti-slip strip is used to prevent the possibility of the pin 11 moving independently, reduce and increase the stability of the pin 11, and improve the press-fitting effect. In addition, the installed rubber layer 2 increases the static friction between the lower car door inner guard plate and the placement plate 3 to ensure that the lower car door inner guard plate will not slide on the surface of the placement plate 3. At the same time, when the placement plate 3 contacts the surface of the base 8 and the two car door inner guard plates are misaligned, the elasticity of the rubber layer 2 itself can be used to further extend the operator's reaction time and minimize the loss of materials.
[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
