[0002] Automotive gears play a key role in multiple systems such as power transmission and mechanical control of automobiles. In automobile transmissions, gear sets are used to change the speed and torque output by the engine to adapt to different driving conditions. In automobile mechanical steering systems, rack and pinion mechanisms are widely used.

[0003] After searching, it was found that the Chinese patent with publication number CN219521868U discloses a fixing tool for automobile gear processing. By providing a fixing plate and a fixing bolt structure combined with an insertion rod and a support tube above the base plate, when processing automobile gears of different shapes, it is only necessary to use the support tube and the insertion rod to complete the preliminary fixation. In this way, there is no need to replace the corresponding automobile gear fixing tool to clamp and fix gears of different shapes. It has strong compatibility and is more convenient to use.

[0004] However, in the prior art, parts are generally clamped and fixed directly, which causes the parts to shift or tilt during the clamping process. In order to solve the problem of part tilt in the prior art and affect the subsequent part processing accuracy, the present application pre-tightens and presses the clamped parts to avoid tilting when the parts are subjected to force and move during the clamping process, thereby achieving the effect of processing accuracy. Therefore, it is necessary to propose a new solution to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the disadvantages of tilting the clamped parts, which affects the subsequent processing accuracy.

[0008] Furthermore, the lifting assembly includes an electric telescopic rod, which is mounted on the sleeve and fixedly connected to one end of the connecting rod.

[0009] Furthermore, a groove is provided in the conical block, one end of the connecting rod is slidably installed in the groove, and a spring is provided between the connecting rod and the groove.

[0010] Furthermore, a limiting shaft is provided inside the spring, one end of the limiting shaft is fixedly connected to the conical block, a limiting groove is provided on the connecting rod, and the limiting shaft is slidably arranged with the limiting groove.

[0011] Furthermore, the cleaning assembly includes a brush plate and a driving member. One end of the brush plate is rotatably connected to the connecting rod through a rotating shaft. A torsion spring is provided between the brush plate and the connecting rod. A fixing bolt is provided on one side of the rotating shaft. The fixing bolt is plugged into the brush plate and the connecting rod. The driving member is provided between the sleeve and the fixed frame.

[0012] Furthermore, the fixing frame includes a servo motor, which is mounted on the fixing frame. The servo motor and the sleeve are both equipped with bevel gears, and the bevel gear on the servo motor is meshed with the bevel gear on the sleeve for transmission.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model is provided with an electric telescopic rod, a connecting rod, a tapered block, a limit shaft, a spring and other components. During the working process, the electric telescopic rod component, the connecting rod component and the tapered block component cooperate with each other to press the parts on the clamping assembly, thereby preventing the parts from tilting during the subsequent clamping process and improving the accuracy of subsequent processing. The spring component and the limit shaft component cooperate with each other to avoid direct rigid connection with the parts and reduce damage to the parts.

[0015] 2. The utility model is provided with components such as a brush plate, a rotating shaft, a torsion spring, and a fixing bolt. During operation, the fixing bolt component and the brush plate component cooperate with each other, and the driving component controls the rotation of the sleeve, and drives the rear connecting rod and the brush plate to rotate accordingly, thereby cleaning the clamping assembly and preventing debris on the surface of the clamping assembly from affecting the clamping of subsequent parts, thereby improving the processing accuracy of the parts, and through the cooperation between the rotating shaft component and the torsion spring component, the torsion spring component drives the brush plate to rotate upward after the fixed removal, thereby avoiding affecting the work of the subsequent conical block.

[0022] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0023] See also Figure 1 、 Figure 2 The fixed tooling for automobile gear processing of the present invention includes a mounting plate 1, on which a clamping assembly is provided. For the clamping assembly, for example, the three-jaw chuck 2 commonly seen on the market, the specific structure and working principle are not described and limited in detail here. A conical block 4 is provided above the clamping assembly, and a connecting rod 5 is provided at the upper end of the conical block 4. A cleaning assembly is provided on the connecting rod 5, a supporting assembly is provided between the connecting rod 5 and the mounting plate 1, and a lifting assembly is provided between the upper end of the connecting rod 5 and the supporting assembly.

[0024] like Figure 2 、 Figure 4 As shown, the support assembly includes a fixed frame 3, which is installed on the mounting plate 1. A sleeve 6 is rotatably installed on the fixed frame 3, and the sleeve 6 is sleeved on the connecting rod 5. The lifting assembly includes an electric telescopic rod 7, which is installed on the sleeve 6. The electric telescopic rod 7 is fixedly connected to one end of the connecting rod 5. The electric telescopic rod 7 is controlled to control the movement of the connecting rod 5, thereby realizing automatic adjustment of the position of the connecting rod 5.

[0025] like Figure 2 、 Figure 3As shown, a groove 8 is provided in the conical block 4, one end of the connecting rod 5 is slidably installed in the groove 8, and a spring 9 is provided between the connecting rod 5 and the groove 8. When the part is pressed by the conical block 4, the spring 9 is compressed, thereby avoiding a rigid connection between the conical block 4 and the part, and avoiding causing greater damage to the workpiece.

[0026] In a preferred embodiment, a limiting shaft 10 is provided on the inner side of the spring 9, one end of the limiting shaft 10 is fixedly connected to the conical block 4, a limiting groove 11 is provided on the connecting rod 5, and the limiting shaft 10 and the limiting groove 11 are slidingly arranged. When the conical block 4 slides on the connecting rod 5, it drives the limiting shaft 10 to move in the limiting groove 11 and limits the moving distance of the conical block 4 to prevent the spring 9 from exceeding the compression range and being damaged.

[0027] like Figure 2 、 Figure 3 As shown, the cleaning assembly includes a brush plate 12 and a driving member. One end of the brush plate 12 is rotatably connected to the connecting rod 5 through a rotating shaft 13. A torsion spring 14 is provided between the brush plate 12 and the connecting rod 5. A fixing bolt 15 is provided on one side of the rotating shaft 13. The fixing bolt 15 is plugged into the brush plate 12 and the connecting rod 5. The position between the brush plate 12 and the connecting rod 5 is restricted by the fixing bolt 15. When the fixing bolt 15 is removed, the fixing restriction on the brush plate 12 is released. The driving member is arranged between the sleeve 6 and the fixing frame 3.

[0028] In this embodiment, the fixed frame 3 includes a servo motor 16, which is installed on the fixed frame 3. Bevel gears 17 are installed on the servo motor 16 and the sleeve 6. The bevel gear 17 on the servo motor 16 is engaged with the bevel gear 17 on the sleeve 6 for transmission. The servo motor 16 drives the sleeve 6 to rotate the rod, thereby driving the brush plate 12 to automatically clean the three-jaw chuck 2, thereby reducing the labor intensity of the staff. The servo motor 16 drives the sleeve 6 to rotate in a circular motion, and the unidirectional rotation range is within two circles.

[0029] The implementation principle is as follows: first, the device is installed on the specified setting through the mounting plate 1, and then one end of the part to be processed is placed on the three-jaw chuck 2, and the electric telescopic rod 7 is controlled to work. The electric telescopic rod 7 drives the connecting rod 5 to move toward the workpiece, and the connecting rod 5 drives the conical block 4 to follow the movement and press the workpiece through the conical block 4, thereby realizing the preliminary limit of the workpiece, and then the three-jaw chuck 2 is driven to clamp and fix the workpiece. After the three-jaw chuck 2 completes the clamping, the electric telescopic rod 7 is controlled to reset. When the workpiece is processed and removed, the staff drives the brush plate 1 2 rotates, and at the same time, the brush plate 12 drives the torsion spring 14 to rotate and store force. When the brush plate 12 is adjusted to the preset position, the position of the brush plate 12 and the connecting rod 5 is restricted by the fixing bolt 15. Then the electric telescopic rod 7 is controlled to work again until the brush plate 12 and the three-jaw chuck 2 are released. Then the servo motor 16 is controlled to work. The servo motor 16 drives the sleeve 6 to rotate through the engagement between the bevel gears 17. The sleeve 6 drives the electric telescopic rod 7 to rotate accordingly, so that the brush plate 12 cleans the three-jaw chuck 2. After cleaning, the reverse operation can be performed and reset.
