Inaccurate positioning during these multiple machining operations significantly impacts machining precision. This repeatable positioning device for automobile model manufacturing can help solve this problem, greatly improving work efficiency. Conventional automobile models are clamped and fixed during machining; however, in current market automobile model manufacturing processes, multiple machining operations require lengthy adjustments for each clamping and positioning step, affecting machining precision each time. Therefore, those skilled in the art have proposed a repeatable positioning device for automobile model manufacturing to address the problems mentioned above. Utility Model Content

[0003] The purpose of this invention is to provide a repeatable positioning device for automobile model processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A repeatable positioning device for automobile model processing includes a base frame. A first bidirectional screw is rotatably connected to the inner cavity of the base frame. A first driving member is installed on the outer wall of one end of the base frame. The output end of the first driving member is connected to one end of the first bidirectional screw. Two movable frames are symmetrically connected to the first bidirectional screw. The outer walls of the two ends of the movable frames abut against the inner walls of the two sides of the base frame, respectively. A first movable plate is connected to the bottom of the movable frame. A threaded sleeve is provided on the first movable plate. The threaded sleeve is threadedly connected to the first bidirectional screw. Two movable blocks are provided inside the movable frames. The position of the movable blocks within the movable frames is adjustable. A mounting post is connected to the top of each movable block. A positioning rod is detachably installed on the top of the mounting post. The top of the positioning rod is used to position the connecting post at the bottom of the model shell.

[0006] As a further embodiment of this utility model: a first bidirectional screw and a fixing rod are symmetrically arranged inside the base frame, and a first movable plate and a second movable plate are symmetrically connected to the bottom end of the movable frame. The second movable plate and the fixing rod are interlocked and connected, and the first bidirectional screw and the fixing rod are parallel to each other.

[0007] As a further embodiment of this utility model: a second bidirectional screw is rotatably connected inside the movable frame, and two movable blocks are symmetrically connected to the second bidirectional screw with threaded engagement. A second driving member is installed on the outer wall of one end of the movable frame, and the output end of the second driving member is connected to one end of the second bidirectional screw. A movable groove for the movable blocks to move is provided at the top of the movable frame, and the bottom end of the movable blocks slides and fits against the bottom surface inside the movable frame.

[0008] As a further improvement of this utility model: the bottom end of the positioning rod is provided with a first insertion hole that cooperates with the mounting post, and the top end of the positioning rod is provided with a second insertion hole that cooperates with the connecting post.

[0009] As a further improvement of this utility model: the mounting post is configured as a rectangular post, and the first insertion hole is configured as a rectangular column-shaped hole.

[0010] This invention has the following advantages: The device adjusts the distance between two movable frames by cooperating with a first driving component, a first bidirectional screw, a first movable plate, and a threaded sleeve. Then, it adjusts the distance between two movable blocks by cooperating with a second bidirectional screw and a second driving component on the movable frames. This allows for flexible adjustment of the positions of the four mounting posts. Positioning rods are detachably mounted on the mounting posts. By flexibly adjusting the positions of the positioning rods, the four positioning rods can quickly position the four connecting posts at the bottom of the model shell. The positioning rods can be replaced with those corresponding to the size of the connecting posts, thus enabling the positioning of different model shells. After one position adjustment, there is no need to repeat the adjustment; the next model shell to be processed can be positioned directly, making the operation convenient and quick.

A first movable plate 6 is connected to the bottom end of the movable frame 5. A threaded sleeve 7 is provided on the first movable plate 6. The threaded sleeve 7 is threadedly connected to the first bidirectional screw 2. Two movable blocks 12 are provided inside the movable frames 5. The position of the movable blocks 12 within the movable frames 5 is adjustable. The top of the model is connected to a mounting post 13, and a positioning rod 14 is detachably mounted on the top of the mounting post 13. The top of the positioning rod 14 is used to position the connecting post 20 at the bottom of the model shell 18. The car model consists of a model base plate 17 and a model shell 18. The bottom of the model base plate 17 has a wheel structure. The bottom of the inner cavity of the model shell 18 is integrally formed with four connecting posts 20 distributed at the corners. The four corners of the model base plate 17 are provided with connecting sleeves 19 that cooperate with the connecting posts 20. When the model base plate 17 is installed to the bottom of the model shell 18, the bottom of the connecting post 20 is inserted into the corresponding connecting sleeve 19. Then, the connecting sleeve 19 and the connecting post 20 are connected together by screws 21, so that the model base plate 17 can be installed to the bottom of the model shell 18.

[0021] Please see Figure 2 , Figure 3 The base frame 1 is symmetrically provided with a first bidirectional screw 2 and a fixing rod 3. The bottom end of the movable frame 5 is symmetrically connected with a first movable plate 6 and a second movable plate 8. The second movable plate 8 is interlocked with the fixing rod 3. The first bidirectional screw 2 and the fixing rod 3 are parallel to each other, thereby ensuring the movement stability of the movable frame 5.

[0022] Please see Figures 1 to 3 The movable frame 5 is rotatably connected to a second bidirectional screw 10. The second bidirectional screw 10 has two symmetrically threaded movable blocks 12 connected to it. A second driving component 11 is installed on the outer wall of one end of the movable frame 5. The output end of the second driving component 11 is connected to one end of the second bidirectional screw 10. The top of the movable frame 5 is provided with a movable groove 9 for the movable blocks 12 to move. The bottom end of the movable blocks 12 slides against the bottom surface of the inner side of the movable frame 5. Both the first driving component 4 and the second driving component 11 are selected as drive motors and are connected to an external control circuit.

[0025] Working principle: In use, a positioning rod 14 corresponding to the size of the connecting post 20 of the model shell 18 is selected. The bottom end of the positioning rod 14 is installed on the corresponding mounting post 13 through the first insertion hole 15. The position of the positioning rod 14 is adjusted according to the position of the four connecting posts 20 of the model shell 18. The first driving component 4 drives the first bidirectional screw 2 to rotate, thereby adjusting the distance between the two movable frames 5. Then, the second driving component 11 drives the second bidirectional screw 10 to rotate, thereby adjusting the position of the two movable blocks 12 in the movable frame 5. This is done in combination to adjust the position of the four positioning rods 14. After that, the model shell 18 is positioned by inserting the connecting post 20 at the bottom of the model shell 18 into the second insertion hole 16 on the corresponding positioning rod 14 to achieve quick positioning of the model shell 18. When processing model shells 18 of the same size in the future, it is not necessary to repeatedly adjust the position of the positioning rod 14.
