[0020] The guide slide 9 provides a guiding path for the movable slide 14, ensuring that its movement direction is accurate.

[0021] The movable slide 14 enables the horizontal displacement adjustment of the entire grinding assembly and has a certain load-bearing capacity to support the weight of the upper tooling assembly and the impact force during grinding.

[0022] The drive mechanism drives the movable slide 14 to slide along the guide slide 9 to achieve automated feeding action.

[0023] Typically, mechanisms such as cylinder drive, hydraulic push rod, and electric push rod are installed at the end of the guide slide 9.

[0024] The movable slide 14 is provided with a through hole, and a rotating shaft seat 13 is rotatably disposed therein. The rotating shaft seat 13 is disposed on the lower surface of the sliding pad support 12. The sliding pad support 12 is provided with a guide sliding shaft 15, and an upper slide 16 is slidably disposed on its outer side. A support pad 7 is disposed on the upper surface of the upper slide 16.

[0026] The pivot seat 13 is embedded in the through hole of the movable slide 14 to realize the rotational connection between the sliding pad support 12 and the movable slide 14, which facilitates angle adjustment.

[0027] The angle adjustment mechanism enables flexible control of the tooling tilt angle.

[0028] The guide sliding shaft 15 is a guide component between the upper slide blocks 16, ensuring the smooth up and down movement of the upper slide blocks 16. It is a high-precision linear guide post, and there are two of them, which are symmetrically arranged to enhance stability.

[0029] A vertical support plate 3 is vertically arranged on the upper surface of the support pad 7. A gear clamping component is arranged on the circumference of the vertical support plate 3. The gear clamping component includes a rotary guide shaft 1 and a gear holder 2. The rotary guide shaft 1 is threaded into a threaded hole on the vertical support plate 3, and its end is provided with a gear holder 2 for clamping the gear.

[0030] The support plate 7 serves as the mounting platform for the vertical support plate 3. Its upper surface is flat, which facilitates the vertical installation of the vertical support plate 3.

[0031] The vertical support plate 3 is the load-bearing structure of the gear clamping component. The gear clamping system is used to fix the gear and keep the gear end face aligned with the grinding head.

[0032] The rotating guide shaft 1 is screwed into the threaded hole on the vertical support plate 3 to achieve fine-tuning of its position, so that the gear holder 2 fits more closely to the outer edge of the gear.

[0033] The outer surface of the rotary guide shaft 1 is threaded and is set to correspond to the threaded hole on the vertical support plate 3, which facilitates fine adjustment on the vertical support plate 3. There are generally 3 of them, which are evenly arranged around the center of the gear to ensure balanced clamping force. By rotating the rotary guide shaft 1, the position of the gear holder 2 can be adjusted arbitrarily to meet the processing needs of bevel gears, irregular gears, etc.

[0034] The gear holder 2 contacts the outer edge of the gear, serving to clamp and position it. Its end has a trapezoidal structure and its surface has been hardened, allowing it to be directly inserted into the gear tooth groove for easy clamping and positioning of the gear.

[0035] Furthermore, a lateral support plate is provided at one end of the movable slide 14, and a positioning seat is provided on the lateral support plate. An angle adjustment shaft 8 is threadedly connected to the positioning seat, and the angle adjustment shaft 8 is rotatably connected to the bottom connecting seat provided on the lower surface of the sliding pad support 12.

[0036] The lateral support plate serves as the mounting bracket for the angle adjustment mechanism, enhancing the overall structural stability.

[0037] The lateral support plate is hinged to the movable slide 14. The positioning seat is used to fix the angle adjustment shaft 8 and provides a threaded connection hole to realize the adjustable installation of the angle adjustment shaft 8. It is threaded on the lateral support plate. The angle adjustment shaft 8 can adjust the extension length by rotating to change the tilt angle of the vertical support plate 3, thereby realizing the angle of the gear end face.

[0038] The angle adjustment shaft 8 has a thread on its outer side, which is screwed into the positioning seat. Its end is hinged to the bottom connecting seat of the sliding pad support 12. The bottom connecting seat is the connection node between the angle adjustment shaft 8 and the sliding pad support 12, and transmits the adjustment force to the sliding pad support 12.

[0039] Furthermore, a lateral adjustment seat 17 for adjusting the position of the upper slide seat 16 is provided on one side of the upper slide seat 16, and the telescopic end of the lateral adjustment seat 17 is connected to a connecting seat provided on the lower surface of the support pad 7.

[0040] The upper slide 16 is a support platform for the support pad 7. It can be slidably adjusted along the guide sliding shaft 15. The surface of the upper slide 16 is provided with a sliding groove to facilitate the installation of the support pad 7. The lateral adjustment seat 17 adopts an electric / pneumatic push rod structure, which is suitable for automation. It can push or pull the upper slide 16 to move laterally through telescopic action. The connecting seat is set on the lower surface of the support pad 7 and serves as the connecting fulcrum of the telescopic end of the lateral adjustment seat 17, transmitting the adjustment force to the upper slide 16.

[0041] Furthermore, the upper surface of the upper slide block 16 is provided with a sliding groove, which corresponds to the guide block provided on the lower surface of the support pad 7.

The intermediate connecting plate 4 is located on the side of the sliding seat outside the sleeved guide sliding shaft 15.

[0043] The side mounting plate 11 is a mounting bracket for the displacement adjustment component 5, which is fixed on one side of the sliding pad support 12 to facilitate auxiliary adjustment of the sliding structure. It is provided with mounting holes to facilitate the stable installation of the displacement adjustment component. The displacement adjustment component 5 provides a precise horizontal direction to control the relative position of the upper slide 16. The intermediate connecting plate 4 is a transition component for connecting the displacement adjustment component 5 to transmit the adjustment force to the slide.

[0044] Furthermore, a guide rail 6 is provided on the guide slide 9, and a movable slide 14 is slidably connected to the guide rail 6.

[0045] Furthermore, the end of the gear holder 2 has a trapezoidal structure.

[0046] In use: Place the gear in the placement hole in 3, and rotate the rotating guide shaft 1 to adjust the position of the gear holder 2 to fix the gear in place. After positioning, adjust the horizontal position of the moving slide 14. After reaching the preset position, the lateral adjustment seat 17 is activated, allowing the upper slide 16 to slide freely along the guide sliding shaft 15. Adjust its vertical position. According to the actual needs or deviation of gear grinding, activate or rotate the displacement adjustment component 5. The displacement adjustment component 5 is activated to fine-tune the position of the gear placed in 3 again. After confirming that the gear is clamped stably and the position is accurate, the grinding operation begins. If tilting is required, the angle adjustment shaft 8 can be rotated to adjust the angle of the sliding pad support 12 to meet the processing needs.
