[0026] 2. By rotating the force rod, the sliding plate connected to its bottom end will rotate with the extrusion cone, and the outer side of the extrusion cone is threadedly connected to the internal gear sleeve. Therefore, the extrusion force between the extrusion cone and the clamping plate can be fine-tuned, thereby achieving more precise clamping of the workpiece and avoiding wear caused by excessive clamping.

The extension of the positioning plate will play a role in positioning the gear tooth height to be processed.

[0028] 4. The cooling nozzle moves both downward and forward, so when the cutting head moves downward and processes the workpiece, the cooling nozzle will first move downward and then extend forward downward to achieve the purpose of cooling and cleaning the processing part of the workpiece. At the same time, it also plays a role in periodically spraying the coolant to prevent waste caused by continuous spraying. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, when the workpiece 1003 is tilted or offset, its position can be quickly changed and repositioned. Both ends of the clamping plate 16 are slidably adapted to the limited sliding rod 17, and the end of the limited sliding rod 17 away from the clamping plate 16 is fixedly connected to the outside of the limit rail 15, and the outside of the limited sliding rod 17 is fixedly connected to a magnetic block 18, and the end of the magnetic block 18 away from the limited sliding rod 17 is provided with a magnetic strip 19, and the magnetic strip 19 is fixedly connected to the inside of the clamping plate 16, wherein the magnetic strip 19 fixedly connected to the inside of the clamping plate 16 maintains a repulsive relationship with the magnetic block 18, so the clamping plate 16 can pre-clamp the workpiece 1003.

[0049] The top of the limit rail 15 is fixedly connected with the electric telescopic rod 10, and the end of the electric telescopic rod 10 away from the limit rail 15 is fixedly connected with a bearing 101. The side of the bearing 101 away from the electric telescopic rod 10 is extruded and adapted with an inner gear sleeve 102, and the inner side of the inner gear sleeve 102 is threadedly connected with an extrusion cone 103. The outer side of the extrusion cone 103 is extruded and adapted with the inner side of the clamping plate 16. The interior of the extrusion cone 103 is provided with an inner groove 104, and the interior of the inner groove 104 is slidably adapted with a sliding plate 105. The top of the sliding plate 105 is fixedly connected with a force rod 106, and the bottom of the sliding plate 105 is fixedly connected with a piston head 107. Then the electric telescopic rod 10 is started again, so that the bearing 101 connected to the telescopic end thereof will move downward with the inner gear sleeve 102 , wherein the inner side of the inner gear sleeve 102 is threadedly connected to the extrusion cone 103, so the extrusion cone 103 will move downward and squeeze the clamping plate 16 outward, and the clamping plate 16 squeezed outward will continuously extrude, clamp and fix the workpiece 1003, wherein the contact surfaces between the extrusion cone 103 and the clamping plate 16 are both curved surfaces, and by rotating the force application rod 106, the sliding plate 105 connected to the bottom end thereof will rotate with the extrusion cone 103, and the outer side of the extrusion cone 103 is threadedly connected to the inner gear sleeve 102, so the extrusion force between the extrusion cone 103 and the clamping plate 16 can be fine-tuned, thereby achieving a more precise clamping of the workpiece 1003 and avoiding the effect of wear caused by excessive clamping.

[0050] The outer side of the extrusion cone 103 is sleeved with a receiving frame 108, and the end of the receiving frame 108 away from the extrusion cone 103 is fixedly connected to a folding air cushion 109, and the end of the folding air cushion 109 away from the receiving frame 108 is extruded and adapted with a positioning plate 100, and the positioning plate 100 is inserted into the inner side of the clamping plate 16 and extends to its outside, and the two ends of the positioning plate 100 are symmetrically connected to side plates 1001, and the outer side of the side plate 1001 is fixedly connected to a return spring 1002, and the end of the return spring 1002 away from the side plate 1001 is fixedly connected to the clamping plate 16. When the workpiece 1003 is clamped, the force rod 106 is manually pushed downward, so that the sliding plate 105 fixedly connected to the bottom end of the force rod 106 will move downward along the inner groove 104, wherein the surface of the sliding plate 105 has a large number of protrusions, so it is aligned with the inner groove 104. A large friction force will be generated between them, and the impact force of the gas accumulated inside the extrusion cone 103 is smaller than the friction force. At the same time, the piston head 107 connected to the bottom of the sliding plate 105 will move downward synchronously and compress the gas accumulated inside the extrusion cone 103, and the compressed gas will pass through the receiving frame 108 and inflate the folding air cushion 109, and then the inflated folding air cushion 109 will extend outward from the receiving frame 108 and squeeze the positioning plate 100 outward, and then the squeezed positioning plate 100 will compress the reset spring 1002 and extend outward through the clamping plate 16, wherein the reset spring 1002 plays a role in resetting the positioning plate 100, and at the same time, the extension of the positioning plate 100 plays a role in positioning the gear tooth height required for processing.

[0051] like Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the processing mechanism 2 includes a supporting folding plate 21, the inner side of the supporting folding plate 21 is fixedly connected to a vertical rail 22, a first screw rod 23 is arranged inside the vertical rail 22, the first screw rod 23 runs through the top of the vertical rail 22, and is connected to a motor 24 through a coupling, the motor 24 is fixedly installed on the top of the vertical rail 22, the outer side of the first screw rod 23 is threadedly connected to a slide bar 25, the side of the slide bar 25 away from the first screw rod 23 is fixedly connected to a central console 26, and the inner sliding adapter of the central console 26 is equipped with a load-bearing column 27, the side of the central console 26 away from the slide bar 25 is fixedly connected with an external slide plate 29, the side of the external slide plate 29 away from the central console 26 is slidably adapted with a shift block 20, the internal rotation of the shift block 20 is connected with a second screw rod 201, the top of the second screw rod 201 is connected with a driver 202 through a coupling, the driver 202 is fixedly installed on the top of the central console 26, the inner side of the shift block 20 is fixedly connected with a control box 203, and the central part of the outer side of the control box 203 is provided with a cutting head 204. After the position of the workpiece 1003 is determined, the motor 24 is started, so that the No. 1 screw rod 23 connected to its output end through the coupling will rotate forward, and then the slide bar 25 threadedly connected to the outer side of the No. 1 screw rod 23 will move downward with the center console 26, wherein the above operation is to fuzzily locate the position of the cutting head 204, and then the driver 202 is started again, so that the No. 2 screw rod 201 connected to its output end through the coupling will rotate forward, wherein the working principle of the driver 202 is the same as that of the servo motor, and then the shifting block 20 threadedly connected to the outer side of the No. 2 screw rod 201 will move downward with the regulating box 203, and then the cutting head 204 connected to the regulating box 203 will move downward together, at this time, the start-up of the driver 202 and the downward movement of the regulating box 203 are the feeding distance of the cutting head 204 to the workpiece 1003, wherein the cutting head 204 is regulated on the regulating box 203, and it can be deflected.

[0052] An external rod 205 is fixedly connected to one side of the shift block 20 away from the regulating box 203, and an end of the external rod 205 away from the shift block 20 is fixedly connected to a No. 1 inclined plate 206, and a No. 2 inclined plate 207 is extruded and adapted at the bottom of the No. 1 inclined plate 206, and an adjustment rod 208 is fixedly connected to the end face of the No. 2 inclined plate 207, and an outer side of the adjustment rod 208 is slidably adapted to be equipped with an arc plate 209, and the arc plate 209 is fixedly connected to the outer side of the load-bearing column 27.

[0053] like Fig.12 , Fig.13 and Fig.14As shown, a cooling assembly 28 is provided inside the center console 26, wherein the cooling assembly 28 includes a double-headed rod 281, one end of the double-headed rod 281 is fixedly connected to the control box 203, and the double-headed rod 281 is slidably adapted in the center of the center console 26 and the external slide plate 29, respectively, and the end of the double-headed rod 281 away from the control box 203 is fixedly connected to a support rod frame 282, and both ends of the support rod frame 282 are inserted into the interior of the inclined rod 283, and the inclined end of the inclined rod 283 is squeezed and adapted with a fixed oblique material 289, and the fixed oblique material 289 is fixedly connected to the inner side of the supporting folding plate 21, and the top of the inclined rod 283 is fixedly connected to a top plate 287, and the side of the top plate 287 close to the support rod frame 282 is fixedly connected to a spring 288. In addition, as the control box 203 moves downward, the double-headed rod 281 connected to its back will move downward with the support rod frame 282, The bevel rod 283, therefore, as the bevel rod 283 moves downward, its bevel end will be squeezed by the fixed bevel material 289, wherein the contact surfaces between the bevel rod 283 and the fixed bevel material 289 are both beveled surfaces, causing the bevel rod 283 to compress the spring 288 and move forward, wherein the spring 288 plays a role in resetting the bevel rod 283, and the other end of the bevel rod 283 is connected to the universal seat 284, and the other end of the universal seat 284 is connected to the cooling nozzle 285, so the cooling nozzle 285 will move downward and forward, so that when the cutting head 204 moves downward and processes the workpiece 1003, the cooling nozzle 285 will first move downward, and then turn downward and extend forward to achieve the purpose of cooling and cleaning the processing part of the workpiece 1003, and at the same time, it also plays a role in periodically spraying the coolant to prevent waste caused by continuous spraying.One end of the spring 288 away from the top plate 287 is fixedly connected to the support rod frame 282, the plane end of the inclined rod 283 is fixedly connected to the universal seat 284, and one end of the universal seat 284 away from the inclined rod 283 is fixedly connected to the cooling nozzle 285, and the bottom of the cooling nozzle 285 is sleeved with a conveying pipe 286. Similarly, the downward movement of the control box 203 causes the external rod 205 connected to it through the shift block 20 to move downward accordingly, and the other end of the external rod 205 is connected to the first inclined plate 206, so the first inclined plate 206 will move downward and squeeze the second inclined plate 207, wherein the contact surfaces between the first inclined plate 206 and the second inclined plate 207 are both inclined surfaces, and the squeezed second inclined plate 207 will carry the adjustment rod 20 8 and moves forward along the curved plate 209, so that the adjusting rod 208 will squeeze the cooling nozzle 285, and the forward extension of the cooling nozzle 285 will also move forward along the surface of the curved plate 209. Therefore, under the action of the universal seat 284, the cooling nozzle 285 that moves downward and extends forward, its water spraying end will be deflected toward the direction of the cutting head 204, and will also be tilted upward, so as to achieve the purpose of accurately cooling and cleaning the processing position of the workpiece 1003. At the same time, the cooling nozzle 285 is extended when in use and retracted into the interior of the center console 26 when not in use, which not only protects the cooling nozzle 285, but also prevents the cooling water from mixing with the high-temperature debris, keeping the cooling water in a brand new state.

[0054] The water spraying end of the cooling nozzle 285 is initially attached to the inner wall of the center console 26 , so the cooling nozzle 285 cannot spray water initially. At the same time, the adjustment rod 208 is reset by the electronic drive component inside the arc plate 209 .

[0055] When the present invention is in use: first, the workpiece 1003 is placed at the same height as the outer side of the clamping plate 16, and then the clamping plate 16 is slightly pushed outward along the limit rail 15, so that the clamping plate 16 will pre-clamp the workpiece 1003, and then the electric telescopic rod 10 is started, so that the bearing 101 connected to the telescopic end thereof will move downward with the inner gear sleeve 102, wherein the inner side of the inner gear sleeve 102 is threadedly connected to the extrusion cone 103, so the extrusion cone 103 will move downward and squeeze the clamping plate 16 outward, and the clamping plate 16 squeezed outward will continuously squeeze, clamp and fix the workpiece 1003. When the workpiece 1003 is clamped, the force rod 106 is manually pushed downward, causing the sliding plate 105 fixedly connected to the bottom end of the force rod 106 to move downward along the inner groove 104. At the same time, the piston head 107 connected to the bottom of the sliding plate 105 will move downward synchronously and compress the gas accumulated inside the extrusion cone 103. The compressed gas will pass through the receiving frame 108 and inflate the folding air cushion 109. Then the inflated folding air cushion 109 will extend outward from the receiving frame 108 and squeeze the positioning plate 100 outward. Then the squeezed positioning plate 100 will compress the return spring 1002 and extend outward through the clamping plate 16.

[0056] When the position of the workpiece 1003 is determined, the motor 24 is started, so that the No. 1 screw rod 23 connected to its output end through a coupling will rotate forward, and then the slide bar 25 threadedly connected to the outer side of the No. 1 screw rod 23 will move downward with the center console 26, and then the driver 202 is started again, so that the No. 2 screw rod 201 connected to its output end through a coupling will rotate forward, and then the shift block 20 threadedly connected to the outer side of the No. 2 screw rod 201 will move downward with the control box 203, and then the cutting head 204 connected to the control box 203 will move downward together to process the workpiece 1003. In addition, as the control box 203 moves downward, the double-headed rod 281 connected to its back will move downward with the support rod frame 282. However, the outer sides of the two ends of the support rod frame 282 are plugged with inclined rods 283. Therefore, as the inclined rod 283 moves downward, its inclined surface end will be squeezed by the fixed inclined material 289, causing the inclined rod 283 to compress the spring 288 and move forward. The other end of the inclined rod 283 is connected to the universal seat 284, and the other end of the universal seat 284 is connected to the cooling nozzle 285. Therefore, the cooling nozzle 285 will move downward. The adjusting rod 208 will move forward along the curved plate 209, so that the adjusting rod 208 will squeeze the cooling nozzle 285, and the cooling nozzle 285 will also move forward along the surface of the curved plate 209.

[0057] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
