Description

Technical Field

[0001] This utility model relates to a mixed field, and more specifically, it relates to a grinding wheel mounting structure for a gear shaft grinding device for automotive transmissions. Background Technology

[0002] The gearbox gear shaft is a key component inside the gearbox in a car or mechanical transmission system. It is responsible for transmitting the engine's power to the drive wheels through a series of gears and allows the driver to change the vehicle's speed and torque as needed.

[0003] The gearbox secondary shaft requires cutting, grinding, and gear grinding during production. Grinding equipment is used when grinding the gearbox gear shaft. Most existing grinding equipment uses grinding wheels to grind the shaft surface, end face, or keyway of the gear shaft. However, grinding the shaft surface, end face, and keyway often requires grinding wheels of different specifications or shapes. In addition, the grinding wheels themselves wear out, so workers often need to replace the grinding wheels frequently. Most existing grinding wheels are fixed by screws and fasteners connected to the screws. When installing and removing the grinding wheels, tools such as wrenches are needed to install and remove them, and a lot of force is often required to complete the installation, which is quite troublesome.

[0004] Based on the above, the purpose of this utility model is to provide a grinding wheel mounting structure for a gear shaft grinding device for automotive transmissions, so as to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a grinding wheel mounting structure for a gear shaft grinding device used in automotive transmissions. This invention features a slider mounted on a housing, with several grippers rotatably connected to the slider. A groove for the slider to move and a cavity for the grippers to unfold are also provided. In use, the grinding wheel is connected to the mounting base, and a rod is inserted into the cavity. A spring pulls the slider, which in turn drives the grippers to converge through the diameter of the cavity and groove, thus clamping the rod. This makes the assembly and disassembly of the grinding wheel more convenient.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grinding wheel mounting structure for a gear shaft grinding device for automotive gearboxes, comprising a housing and a mounting base. A slider is slidably connected inside the housing, and three or more grippers are rotatably connected to the slider. The housing is provided with a sliding groove for the slider to move and a cavity for the grippers to unfold. The diameter of the cavity is larger than that of the sliding groove. The slider is also provided with a lever and a spring fixedly connected to one end. The other end of the lever extends outside the housing, and the other end of the spring is fixedly connected to the inner wall of the sliding groove. The housing is provided with a moving groove for the lever to extend and move. An insert rod and several limiting rods are fixedly connected to the mounting base. The insert rod is provided with a gripping plate for the grippers to grasp. The housing is provided with a limiting groove for the limiting rod to be inserted and a feed port for the insert rod to be inserted into the cavity.

[0007] By adopting the above technical solution, the housing is rotatably mounted on the grinding equipment, and then connected to the drive mechanism such as the motor. When it is necessary to install the grinding wheel, the insert rod is passed through the mounting hole in the middle of the grinding wheel, while multiple limit rods pass through several positioning holes of the grinding wheel. Then, the lever is pressed down, causing multiple grippers to move into the cavity. The insert rod is then inserted into the cavity through the feed port, positioning the gripper plate between the grippers. The lever is then released, and the slider moves away from the grinding wheel under the action of the spring, thus moving the grippers into the slide groove. During this process, because the diameter of the slide groove is smaller than that of the cavity, the grippers converge towards the center until they clamp the gripper plate and cannot be lifted further, thus clamping the grinding wheel between the mounting base and the housing. During this process, the limit rods are inserted into the limit grooves. When it is necessary to replace or remove the grinding wheel, the lever is pressed down until the grippers release the gripper plate, and the insert rod can be pulled out. This design makes the installation and removal of the grinding wheel more convenient.

[0008] The present invention is further configured such that: a plug is slidably connected to the housing, a slot for inserting the plug is provided on the slider, a bolt is provided on the plug with one end rotatably connected thereto, and the other end of the bolt is threadedly connected to the housing.

[0009] The present invention is further configured such that both the insert and the slot are trapezoidal.

[0010] The present invention is further configured such that the bolt is a wing bolt.

[0011] The present invention is further configured such that: a torsion spring is provided at the rotational connection between the gripper and the slider, and the two ends of the torsion spring are respectively fixedly connected to the gripper and the slider.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention features a slider mounted on the housing, with several grippers rotatably connected to the slider. A groove for the slider to move and a cavity for the grippers to unfold are also provided. In use, the grinding wheel is connected to the mounting base, and a rod is inserted into the cavity. The slider is then pulled by a spring, which in turn drives the grippers to converge through the diameter of the cavity and groove, clamping the grinding wheel between the mounting base and the housing until it can no longer be lifted. Inserts and slots are also provided on the housing and slider. A butterfly-shaped spiral drives the inserts into the slots, further limiting the slider's position and making the assembly and disassembly of the grinding wheel more convenient.

[0022] A grinding wheel mounting structure for a gear shaft grinding device for automotive transmissions, such as... Figures 1-2 As shown, the device includes a housing 1 and a mounting base 2. A slider 3 is slidably connected inside the housing 1. More than three grippers 4 are rotatably connected to the slider 3. The housing 1 has a sliding groove 5 for the slider to move and a cavity 6 for the grippers 4 to unfold. The diameter of the cavity 6 is larger than that of the sliding groove 5. The slider 3 also has a lever 7 and a spring 8 fixedly connected to one end. The other end of the lever 7 extends outside the housing 1. The other end of the spring 8 is fixedly connected to the inner wall of the sliding groove 5. The housing 1 has a moving groove 9 for the lever 7 to extend and move. An insertion rod 10 and several limiting rods 11 are fixedly connected to the mounting base 2. A gripping plate 12 for the grippers 4 to grasp is fixedly connected to the insertion rod 10. The housing 1 has a limiting groove 13 for the limiting rod 11 to be inserted and a feed port 14 for the insertion rod 10 to be inserted into the cavity 6.

[0023] Furthermore, a plug 15 is slidably connected to the housing, and a slot 16 is provided on the slider for the plug 15 to be inserted. The plug 15 is provided with a bolt 17 at one end rotatably connected to it, and the other end of the bolt 17 is threadedly connected to the housing 1.

[0024] Furthermore, both the front end of the insert 15 and the slot 16 are trapezoidal.

[0025] Furthermore, bolt 17 is a wing bolt 17.

[0026] Furthermore, a torsion spring is installed at the rotatable connection between the gripper 4 and the slider 3, with both ends of the torsion spring fixedly connected to the gripper 4 and the slider 3 respectively.

[0027] Furthermore, the slide 5 is arranged in a funnel shape.

[0028] Working principle: The housing 1 is rotatably mounted on the grinding equipment, and then the housing 1 is connected to a drive mechanism such as a motor. It can be driven to rotate by the motor or other drive structure. When it is necessary to install the grinding wheel, the insert rod 10 is passed through the mounting hole in the middle of the grinding wheel, and at the same time, multiple limit rods 11 pass through several positioning holes of the grinding wheel. Then, the lever 7 is pressed down, which causes multiple grippers 4 to move into the cavity 6. Under the action of the torsion spring, the multiple grippers 4 will unfold in the cavity 6. Then, the insert rod 10 is inserted into the cavity 6 through the feed port 14, so that the gripper plate 12 is located between the multiple grippers 4. Then, the lever 7 is released, and the slider 3 will move away from the grinding wheel under the action of the spring 8. The movement causes multiple grippers 4 to move into the slide groove 5. During this process, because the slide groove 5 is funnel-shaped and its diameter is smaller than that of the cavity 6, the grippers 4 will gradually converge towards the center under the drive of the inner wall of the slide groove 5 until the gripper plate 12 is clamped and the insert rod 10 can no longer be lifted. This clamps the grinding wheel between the mounting base 2 and the housing 1. During this process, the limiting rod 11 will be inserted into the limiting groove 13, and then the wing bolt will be rotated to drive the insert block 15 to be inserted into the slot 16. Since both the insert block 15 and the slot 16 are trapezoidal, the insert block 15 will limit the slider 3 through the slot 16 while driving the slider 3 to rise, making the clamping effect on the grinding wheel more stable. When it is necessary to replace or remove the grinding wheel, press down the lever 7 until the grippers 4 release the gripper plate 12, and then the insert rod 10 can be pulled out. This design makes the installation and removal of the grinding wheel more convenient.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
