[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a positioning device for machining automobile cranks includes a base 1, a machining box 10 is mounted on the base 1, and multiple slots 13 arranged in a linear array are symmetrically opened on both sides of the machining box 10. A frame 14 is mounted inside the slots 13, and a rotating shaft 15 is mounted inside the frame 14. Multiple fan blades 16 arranged in a circumferential array are mounted on the rotating shaft 15. Multiple ventilation slots 18 arranged in a linear array are symmetrically opened on both sides of the machining box 10. Multiple material drop slots 21 arranged in a linear array are mounted at the connection between the base 1 and the machining box 10.

[0025] Specifically, in use, the car gear lever is placed in the processing box 10 on the base 1, and then the gear lever in the processing box 10 is cut. Then, the rotating shaft 15 in the frame 14 is started, causing the rotating shaft 15 to rotate and drive multiple fan blades 16 arranged in a circular array to rotate. The scrap material produced after cutting is blown off the gear lever and falls into the material drop chute 21 at the connection between the processing box 10 and the base 1, and then into the base 1 for collection. At the same time, the ventilation slots 18 on both sides dissipate heat from the processing box 10.

[0026] In the above scheme, the car gear lever is processed by the processing box 10 on the base 1. The rotating shaft 15 is installed by the slot 13 on the processing box 10 and the frame 14 inside the slot 13. The temperature inside the processing box 10 is dissipated by the multiple fan blades 16 arranged in a circular array on the rotating shaft 15. The heat dissipation inside the processing box 10 is achieved by the multiple ventilation slots 18 on both sides of the processing box 10. The material discharge slot 21 opened at the connection between the base 1 and the processing box 10 enables the scrap material of the car gear lever to be discharged into the base 1 during cutting.

[0027] As a further embodiment provided by this utility model, according to Figure 1 and Figure 2 As shown, a placement seat 3 is symmetrically arranged on the base 1, and a sliding groove 31 is symmetrically opened on the placement seat 3. A sliding rod 33 is slidably arranged in the sliding groove 31.

[0028] Furthermore, the slide groove 31 is provided with a plurality of elastic elements 32 arranged in a linear array, the other end of the elastic element 32 is provided on the slide rod 33, and a bearing part 35 is provided between two slide rods 33, the bearing part 35 being arc-shaped.

[0029] Specifically, the gear lever is placed on the support part 35 on the placement seat 3. At the same time, the support part 35 moves downward in the slide groove 31 through the slide rod 33, and the multiple elastic members 32 at the bottom of the slide groove 31 move downward to bear the force, thus supporting the gear lever. Meanwhile, the arc-shaped support part 35 prevents the gear lever from being damaged when it is fixed. When the support part 35 moves downward, it will drive the connecting member 331 to move downward and drive the upright plate 36 to deflect. After the two upright plates 36 deflect, the screw 38 is rotated to drive the fixing plate 39 to move, so that the two fixing plates 36 are attached to the car gear lever to prevent the car gear lever from shaking up and down.

[0030] As a further embodiment provided by this utility model, according to Figure 2 As shown, robotic arms 19 are symmetrically arranged inside the processing box 10, and processing rods 20 are arranged on the robotic arms 19.

[0031] Specifically, the stop bar is machined by the machining rod 20 on the robotic arm 19.

[0032] As a further embodiment provided by this utility model, according to Figure 2 As shown, upright plates 36 are symmetrically arranged on the placement base 3. Threaded grooves 37 are opened on the upright plates 36. A screw 38 is threaded in the threaded grooves 37. A limit plate 361 is provided at the bottom of the upright plates 36.

[0033] Furthermore, a fixing plate 39 is provided at one end of the screw 38, and a plurality of anti-slip parts 40 arranged in a linear array are provided on the fixing plate 39, and a nut 381 is provided at the other end of the screw 38.

[0034] Specifically, rotating the nut 381 causes the screw 38 to rotate. At the same time, the screw 38 rotates in the threaded groove 37 on the vertical plate 36 and pushes the vertical plate 36 to move, thus fixing the stop bar fixed on the placement seat 3. Meanwhile, the anti-slip part 40 prevents it from sliding during fixing.

[0035] As a further embodiment provided by this utility model, according to Figure 2 As shown, a door 11 is provided on the processing box 10, and the door 11 is rotatably mounted on the processing box 10. A handle 12 is provided on the processing box 10.

[0036] Specifically, the door 11 is opened on the processing box 10, and the stop bar is fixed or removed.

[0037] Working principle: The car gear lever is placed on the support part 35 of the placement seat 3 inside the processing box 10 on the base 1. At the same time, the support part 35 moves downward in the slide groove 31 through the slide rod 33, and the multiple elastic elements 32 at the bottom of the slide groove 31 move downward to bear the force, thus supporting the gear lever. At the same time, the arc-shaped support part 35 prevents damage to the gear lever when it is fixed. Simultaneously, when the support part 35 moves downward, it drives the connecting part 331 to move downward and causes the upright plate 36 to deflect, preventing the car gear lever from shaking up and down. Then, the nut 381 is turned, which drives the screw 38 to rotate. At the same time, the screw 38 rotates in the threaded groove 37 opened on the upright plate 36. The upright plate 36 is moved so that the two fixed plates 36 are attached to the car gear lever. At the same time, the anti-slip part 40 prevents the gear lever from sliding during fixing. Then the gear lever inside the processing box 10 is cut. Then the rotating shaft 15 inside the frame 14 is started so that the rotating shaft 15 rotates and drives multiple fan blades 16 arranged in a circular array to rotate. The scrap material generated after cutting is blown off the gear lever and falls into the material drop chute 21 at the connection between the processing box 10 and the base 1, and falls into the base 1 for collection. At the same time, the ventilation slots 18 on both sides dissipate heat inside the processing box 10. Then the door 11 is opened on the processing box 10 to fix or remove the gear lever.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
