Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to a pre-positioning fixture for welding new energy vehicle frames. Background Technology

[0002] In traditional body-in-white manufacturing processes, the assembly of the side panels and the lower body mainly relies on manual operation. Workers need to manually lift the side panels and the lower body to assemble them, and pre-fix the body by tapping the fasteners.

[0003] This operating mode has significant drawbacks: on the one hand, the manual lifting of heavy objects seriously violates the principles of ergonomics and is very likely to cause physical injury to the operators; on the other hand, manual operation is inefficient and cannot meet the pace requirements of modern large-scale production; in addition, the process of striking the buckle and other operations poses significant safety hazards and is likely to cause personal injury and equipment damage. There is an urgent need for a more efficient, safe, and precise technical solution to replace it. Therefore, this utility model proposes a pre-positioning fixture for welding the frame of a new energy vehicle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pre-positioning fixture for welding the frame of a new energy vehicle. It uses a robotic gripper to replace manual operation, realizes automatic gripping of the side panel and precise assembly to the lower body. The gripper completes the initial fixed connection between the side panel and the lower body by flipping the buckles on the side panel, effectively solving a series of problems existing in traditional processes.

[0005] To solve the above-mentioned technical problems, the present invention provides a pre-positioning fixture for welding a new energy vehicle frame, including a mounting frame, wherein a gun changing disc is bolted to the bottom center of the mounting frame to drive the mounting frame to adjust the adaptation angle.

[0006] The top of the mounting bracket is bolted with three push-type latching mechanisms and one flip-type latching mechanism to clamp and fix the vehicle side panel.

[0007] The top of the mounting bracket is bolted with multiple limiting mechanisms and positioning components to limit and secure the side of the vehicle.

[0008] The present invention is further configured such that: two of the aforementioned push-type hook and loop mechanisms are located at the middle and end positions of the mounting frame, respectively; another push-type hook and loop mechanism is located between the two aforementioned push-type hook and loop mechanisms; and the flip-type hook and loop mechanism is located at the other end of the mounting frame.

[0009] The above technical solution utilizes three push-type latching mechanisms to press and fix the side panel, and further utilizes a flip-type latching mechanism to clamp and fix the car side panel, facilitating its overall assembly.

[0010] The present invention is further configured such that: the direct-push buckle mechanism includes a mounting block bolted to a mounting frame; a first cylinder is bolted to the side wall of the mounting block; an adjusting frame is bolted to the end face of the drive rod of the first cylinder; a fixing plate is bolted to the top of the adjusting frame; a direct-push cylinder is bolted to one side of the fixing plate; a clamping block is bolted to the end face of the drive rod of the direct-push cylinder; and an auxiliary component is bolted to the adjacent wall of the fixing plate and the direct-push cylinder.

[0011] Using the above technical solution, the first cylinder is activated, and its drive rod drives the adjustment frame on the end face to rotate, thereby facilitating the installation and fixing of the fixing plate in a suitable position. Then, the direct push cylinder is activated, and its drive rod drives the end face abutment block to move, so that it can work with external auxiliary parts to press and fix the side wall.

[0012] The present invention is further configured such that: the flip-type latch mechanism includes a mounting base mounted on a mounting frame, a fixing frame bolted to the side wall of the mounting base, a flip cylinder bolted to the bottom of the fixing frame, a rotating plate rotatably connected to the end face of the drive rod of the flip cylinder, a movable plate rotatably connected to the top of the rotating plate, and a pressure block bolted to the top of the movable plate.

[0013] By using the above technical solution, the tilting cylinder is activated, and its driving end drives the rotating plate on the end face to rotate on the fixed frame, thereby driving the pressure block on the end face to press and fix the side wall at the corresponding position.

[0014] The present invention is further configured such that: the rotating plate is rotatably connected to the inside of the fixed frame near the bottom position, and the rotating plate is movably connected to the positioning shaft connected to the inside of the fixed frame near the top through a movable groove opened on its top.

[0015] The above technical solution allows the rotating plate to move within a certain space inside the fixed frame when it is driven, thereby enabling the side panel to be pressed and fixed in a flip-type manner.

[0016] The present invention is further configured such that: there are nine limiting mechanisms, and each limiting mechanism includes a mounting plate mounted on a mounting frame. A limiting cylinder is bolted to the side wall of the mounting plate. A limiting frame and a connecting frame are fixedly connected to the end face of the drive rod of the limiting cylinder. A reinforcing frame is bolted to the top of the connecting frame. The other end of the reinforcing frame is bolted to the top of the mounting plate.

[0017] The above technical solution activates the limiting cylinder, whose drive rod rotates the limiting frame on the end face, thereby enabling the limiting frame to be in a specific limiting position. At the same time, the cooperation of multiple limiting frames can fix the side wall in a certain position.

[0018] The present invention is further configured such that: the mounting plates inside the two limiting mechanisms are bolted to the side of the limiting cylinder with a side frame, the side frame is bolted to an L-shaped frame, the end face of the L-shaped frame is fixedly connected to a positioning pin, and the positioning assembly is provided with a positioning column to cooperate with the positioning pin to form a three-point positioning.

[0019] The above technical solution utilizes positioning pins mounted on the mounting plate to position and fix the car side panel, enabling rapid positioning and installation during assembly. Simultaneously, the positioning components work together to perform three-point positioning of the side panel, improving positioning accuracy.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model proposes a pre-positioning fixture for welding the frame of a new energy vehicle. It uses a robotic gripper to replace manual operation, realizes automatic gripping of the side panel, and accurately assembles it into the lower body.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figures 1-3 As shown, a pre-positioning fixture for welding a new energy vehicle frame includes a mounting frame 1. A gun-changing disc 2 is bolted to the bottom center of the mounting frame 1 to drive the mounting frame 1 to adjust its adaptation angle. Three push-type latching mechanisms 3 and one flip-type latching mechanism 5 are bolted to the top of the mounting frame 1 to clamp and fix the vehicle side panel. Two push-type latching mechanisms 3 are located at the middle and end positions of the mounting frame 1, respectively, and another push-type latching mechanism 3 is located between the two push-type latching mechanisms 3. The flip-type latching mechanism 5 is located at the other end of the mounting frame 1. The three push-type latching mechanisms 3 can press and fix the side panel, and the flip-type latching mechanism 5 can further clamp and fix the vehicle side panel, facilitating overall assembly. The fastening mechanism 3 includes a mounting block 31 bolted to the mounting frame 1. A first cylinder 32 is bolted to the side wall of the mounting block 31. An adjusting frame 33 is bolted to the end face of the drive rod of the first cylinder 32. A fixing plate 34 is bolted to the top of the adjusting frame 33. A direct-push cylinder 35 is bolted to one side of the fixing plate 34. A clamping block 36 is bolted to the end face of the drive rod of the direct-push cylinder 35. An auxiliary component 37 is bolted to the adjacent wall of the fixing plate 34 and the direct-push cylinder 35. When the first cylinder 32 is started, its drive rod drives the adjusting frame 33 at the end face to rotate, thereby facilitating the installation and fixing of the fixing plate 34 in a suitable position. Then, the direct-push cylinder 35 is started, causing its drive rod to move the clamping block 36 at the end face, so that it can press and fix the side wall in conjunction with the external auxiliary component 37.

[0030] like Figure 5As shown, the flip-type latch mechanism 5 includes a mounting base 51 mounted on a mounting frame 1. A fixing frame 52 is bolted to the side wall of the mounting base 51. A flip cylinder 53 is bolted to the bottom of the fixing frame 52. A rotating plate 54 is rotatably connected to the end face of the drive rod of the flip cylinder 53. The rotating plate 54 is rotatably connected to the inside of the fixing frame 52 near the bottom. The rotating plate 55 is movably connected to the positioning shaft inside the fixing frame 52 near the top through a movable slot on its top. This allows the rotating plate 54 to move within a certain space inside the fixing frame 52 when driven, thereby enabling flip-type pressing and fixing of the side panel. A movable plate 55 is rotatably connected to the top of the rotating plate 54. A pressure block 56 is bolted to the top of the movable plate 55. When the flip cylinder 53 is activated, its drive end drives the rotating plate 54 on the end face to rotate in the fixing frame 52, thereby driving the pressure block 56 on the end face to press and fix the side panel at the corresponding position.

[0031] like Figure 1 and Figure 4 As shown, the top of the mounting bracket 1 is bolted with multiple limiting mechanisms 4 and positioning components 6 to limit and fix the side of the vehicle. Nine limiting mechanisms 4 are provided, and each limiting mechanism 4 includes a mounting plate 41 mounted on the mounting bracket 1. Two of the limiting mechanisms 4 have mounting plates 41 bolted to a side bracket 42 adjacent to the limiting cylinder 45. An L-shaped bracket 43 is bolted to the side bracket 42, and a positioning pin 44 is fixedly connected to the end face of the L-shaped bracket 43. The positioning component 6 has a positioning post to cooperate with the positioning pin 44 to form a three-point positioning. Using the positioning pin 44 mounted on the mounting plate 41, the side of the vehicle can be positioned and fixed, thereby... During assembly, it can be quickly positioned and installed. At the same time, it works with positioning component 6 to perform three-point positioning of the side wall, improving the positioning accuracy. The side wall of mounting plate 41 is bolted to limit cylinder 45. The end face of the drive rod of limit cylinder 45 is fixedly connected to limit frame 46 and connecting frame 47. The top of connecting frame 47 is bolted to reinforcement frame 48. The other end of reinforcement frame 48 is bolted to the top of mounting plate 41. When limit cylinder 45 is activated, its drive rod drives the limit frame 46 on the end face to rotate, so that the limit frame 46 can be in a specific limit position. At the same time, the cooperation of multiple limit frames 46 can fix the side wall in a certain position.

[0032] In use, this utility model first uses multiple limiting mechanisms 4 and their internal positioning pins 44 in conjunction with positioning components 6 to position and fix the side panel of the car. Then, it uses a push-type buckle mechanism 3 and a flip-type buckle mechanism 5 to clamp and fix the side panel after limiting. Finally, it uses a gun-changing disc 2 to drive the entire mounting frame 1 to assemble the side panel of the car.
