[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a quick-change positioning device for a gear hobbing machine, comprising:

[0027] The support assembly 100 includes a fixing member 101, a connector 102 sleeved on the inner side of the end of the fixing member 101, a support plate 103 slidably inserted into the bottom of the connector 102, an adapter plate 104 rotatably installed on the bottom of the support plate 103, and a gear cutter 105 snapped into the end of the adapter plate 104.

[0028] The adjusting assembly 200 includes a connecting rod 201 fixedly connected to the end of the connector 102, a positioning block 202 fixedly connected to the middle side wall of the connecting rod 201, an adjusting block 203 snapped into the side wall of the fixing member 101, and a lead screw 204 rotatably installed inside the support plate 103. The connecting rod 201 is movably inserted into the inner wall of the fixing member 101, the positioning block 202 is slidably connected to the middle of the inner groove of the fixing member 101, the end of the adjusting block 203 is inserted into the side wall of the positioning block 202, and the end of the lead screw 204 is threadedly connected to the end of the connector 102.

[0029] The fastener 101 is used to connect the connector 102 to enhance the stability of their connection. The support plate 103 is installed at the bottom of the connector 102 via a sliding insertion method, and can slide up and down under the constraint of the connector 102. It cooperates with the adapter plate 104 to fix the gear hobbing cutter 105, providing an installation base for the gear hobbing cutter 105. This facilitates the disassembly and maintenance of the gear hobbing cutter 105 through the adapter plate 104, enabling quick replacement and positioning of the gear hobbing cutter 105. The positioning block 202 is fixedly connected to the middle side wall of the connecting rod 201 and moves with the connecting rod 201, achieving precise sliding positioning within the fastener 101. The positioning block 202 and the entire adjustment assembly are fixed by the adjustment block 203 engaging with it. Loosening the adjustment block 203 allows for easy adjustment of the height of the connecting component above the gear hobbing cutter 105 to adapt to different product processing requirements. By rotating the lead screw 204, the connecting piece 102 can be moved axially using the thread transmission principle, thereby adjusting the horizontal position of the gear hobbing cutter 105.

[0030] Specifically, the adjustment assembly 200 also includes a handle bolt 205 inserted in the middle of the adjustment block 203, with the end of the handle bolt 205 threadedly connected to the center of the positioning block 202.

[0031] By rotating the handle bolt 205, the clamping or loosening state between the adjusting block 203 and the positioning block 202 can be changed, thereby precisely controlling the position of the positioning block 202 in the groove of the fixing member 101, and realizing fine adjustment and locking of the position of the entire adjusting component.

[0032] Furthermore, the sidewalls of the fastener 101 and the adjusting block 203 are provided with anti-slip textures for matching use, and the sidewalls of the fastener 101 and the adjusting block 203 are tightly fitted together.

[0033] The anti-slip texture of the adjusting block 203 and the side wall of the fixing member 101 are matched to ensure the stability after adjustment and prevent the connecting parts of the side wall of the adjusting block 203 from loosening.

[0034] Furthermore, the side wall of the positioning block 202 is provided with a stepped edge structure, and the side wall of the fixing member 101 is provided with a groove structure that fits with the stepped edge of the side wall of the positioning block 202.

[0035] The positioning block 202 has a stepped edge structure on its side wall, which fits tightly with the sliding groove structure on the side wall of the fixing member 101, so as to achieve precise sliding positioning within the fixing member 101.

[0036] Preferably, the adjustment assembly 200 further includes a baffle 206 hinged to the side wall of the adapter plate 104, the baffle 206 being sleeved on the side wall of the gear cutter 105, and the end of the baffle 206 being fixedly connected to the end of the adapter plate 104.

[0037] The baffle 206 is sleeved on the side wall of the gear hobbing cutter 105, and its end is fixedly connected to the end of the adapter plate 104. It is used to protect and limit the gear hobbing cutter 105, prevent the gear hobbing cutter 105 from being accidentally displaced during operation, and remove the locking part at the end of the baffle 206 to facilitate the rotation of the baffle 206 for disassembly and maintenance of the gear hobbing cutter 105.

[0038] It should be noted that the adjustment assembly 200 also includes a fastening bolt 207 inserted into the side wall of the adapter plate 104. The end thread of the fastening bolt 207 is in the middle of the through hole in the side wall of the support plate 103, and the side wall of the adapter plate 104 is provided with an arc-shaped groove structure that cooperates with the fastening bolt 207.

[0039] By loosening the fastening bolt 207 and then rotating the adapter plate 104, the rotation angle of the adapter plate 104 relative to the support plate 103 can be changed, thereby adjusting and fixing the working angle of the gear hobbing cutter 105.

[0040] Preferably, the bottom of the support plate 103 is provided with a stepped edge structure that cooperates with the adapter plate 104, and the end of the adapter plate 104 is provided with a retaining edge structure that matches the side wall of the support plate 103. The end of the lead screw 204 is fixedly connected to a handle installed on the outside of the adapter plate 104.

[0041] The support plate 103 has a stepped edge structure at the bottom that works with the adapter plate 104, which enables precise docking and cooperation with the adapter plate 104. A handle is added to facilitate the rotation of the lead screw 204 and adjust the relative position of the adapter plate 104 and the support plate 103.

[0042] In use, when positioning the gear hobbing cutter 105 is required, the handle at the end of the lead screw 204 is rotated. The rotation of the lead screw 204 drives the connecting member 102 to move axially. This causes the positioning block 202 to slide within the groove on the inner side of the fixing member 101, thus achieving initial adjustment of the height of the support plate 103. After the support plate 103 has moved to the appropriate position, if fine adjustment of the position of the positioning block 202 is required, the operator can rotate the handle bolt 205. The rotation of the handle bolt 205 pushes the adjusting block 203 to move on the side wall of the fixing member 101, thereby fine-tuning the position of the positioning block 202 within the groove of the fixing member 101, achieving precise locking of the entire adjusting assembly. At this time, the positioning block 202 stably fixes the position of the connecting member 102 through the connecting rod 201. When maintenance of the gear hobbing cutter 105 is required, the locking component at the end of the baffle 206 is removed, the baffle 206 is rotated, and the gear hobbing cutter 105 is removed from the middle of the baffle 206 for maintenance.

[0043] To adjust the working angle of the gear hobbing cutter 105, the operator loosens the fastening bolt 207 and rotates the adapter plate 104. The adapter plate 104 rotates around the rotation connection point with the support plate 103, while the fastening bolt 207 moves within the arc-shaped groove on the side wall of the adapter plate 104. Once the adapter plate 104 has rotated to the appropriate angle, the fastening bolt 207 is tightened to fix the adapter plate 104 onto the support plate 103, thereby adjusting the working angle of the gear hobbing cutter 105.

[0044] In summary, through the ingenious design of each component of the support assembly, such as the sliding connection between the support plate 103 and the connector 102, the rotating connection between the adapter plate 104 and the support plate 103, and the snap-fit ​​connection between the gear shaper 105 and the adapter plate 104, the gear shaper 105 can be easily and quickly changed, reducing changeover time and improving work efficiency. The precise fit between the positioning block 202 and the sliding groove of the fixing component 101 in the adjustment assembly, and the precise fine-tuning of the position of the positioning block 202 through the handle bolt 205 and the adjusting block 203, enables high-precision positioning of the gear shaper 105, ensuring the accuracy requirements of gear shaping and improving product quality. The adapter plate 104 can rotate around the support plate 103, and the rotation angle can be precisely adjusted through the fastening bolt 207 and the arc-shaped groove structure, allowing the gear shaper 105 to work at multiple angles, meeting the diverse needs of different processing techniques for gear shaper angles, and enhancing the versatility and adaptability of the gear shaper machine. The baffle 206 effectively protects the gear hobbing cutter 105, preventing debris from splashing and damaging the cutter during operation. It also limits the gear hobbing cutter 105, preventing accidental displacement during operation and ensuring the safety and stability of the gear hobbing process.
