[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention cooperates with the first clamping gear and the second clamping gear, so that the device can insert the positioning pin into the interior of the through hole, so that the first clamping gear and the second clamping gear can be rotated to both sides respectively with the positioning pin as the axis, so that the middle is opened and the torsion bar spring can be placed in the interior of the first clamping gear and the second clamping gear, so as to clamp the torsion bar spring, and through the cooperation of the semi-dome block and the compression spring, when the first clamping gear and the second clamping gear clamp the torsion bar spring, the semi-dome block can be subjected to the elastic potential energy of the compression spring and pop outward, so that the semi-dome block is closely attached to the surface of the torsion bar spring, so that the torsion bar spring is tightened, and the torsion bar spring is prevented from loosening and shaking, and the device can clamp torsion bar springs of different sizes;

[0020] 2. The present invention cooperates with the pushing ring and the positioning pin. When the positioning pin is inserted into the interior of the through hole, the pushing ring will resist the driving gear and push the driving gear in the direction of the servo motor, so that the driving gear moves through the sliding groove on the surface of the rotating shaft through the sliding buckle, thereby releasing the meshing between the driving gear and the gear composed of the first clamping gear and the second clamping gear, and at the same time, the driving gear and the driven gear are meshed, so that when the device is in use, the through hole can be positioned by the positioning pin, so that when the first clamping gear and the second clamping gear rotate, they will definitely wait until the through hole rotates to the position of the positioning pin, and then the positioning pin will be inserted into the interior of the through hole to stop the first clamping gear and the second clamping gear from rotating, thereby preventing the first clamping gear and the second clamping gear from being unable to rotate to both sides to open, and at the same time positioning the position of the torsion bar spring, so as to facilitate the positioning of the position of the torsion bar spring that needs to be processed, thereby preventing the two ends of the torsion bar spring from being asymmetrical during processing;

[0021] 3. The present invention cooperates with the T-shaped slider and the fan-shaped arc plate so that when the device is in use, after the semicircular arc limit plate moves to both sides, the linear motor drives the T-shaped slider to rise inside the T-shaped slide groove, so that the T-shaped slider drives the connecting rod and the fan-shaped arc plate to rise. At this time, the surface of the fan-shaped arc plate fits with the surface of the torsion bar spring to move the torsion bar spring upward. When the torsion bar spring moves upward, it will hit the upper end surface position of the inner side of the first clamping gear and the second clamping gear, thereby further applying force to the first clamping gear and the second clamping gear, so that the first clamping gear and the second clamping gear can be opened to both sides, preventing the first clamping gear and the second clamping gear from being unable to be opened directly by gravity. At the same time, when the fan-shaped arc plate rises, it will drive the rotating plate to rise. Since the outer diameter of the rotating plate is larger than the distance between the fan-shaped arc plate and the positioning plate, the surface of the rotating plate will remain tangent to the torsion bar spring The state rises until the rotating plate moves to the upper position of the inclined plate. At this time, the rotating plate will rotate downward due to gravity, so that the rotating plate rotates to the position where the positioning plate and the inclined plate are connected. At this time, the torsion bar spring will roll along the surface of the rotating plate and the surface of the inclined plate to the inside of the collecting box, thereby completing the unloading of the torsion bar spring. At this time, the T-type slider will drive the fan-shaped arc plate to descend, and at the same time, another torsion bar spring will be added to the inside through the feed box. The unprocessed torsion bar spring will fall downward and fall on the surface of the fan-shaped arc plate. When the fan-shaped arc plate descends, the bottom end surface of the rotating plate contacts the position where the positioning plate and the inclined plate are connected and force is applied, thereby causing the rotating plate to rotate upward until it fits with the surface of the unprocessed torsion bar spring and makes its surface tangent to the torsion bar spring, thereby preventing the torsion bar spring from rolling into the inside of the collecting box. When the T-type slider returns to its original position, the torsion bar spring can be processed by the processing table. BRIEF DESCRIPTION OF THE DRAWINGS

The positioning pin 408 is fixedly installed on the outer side of the sliding table 405 near the top.

[0037] By adopting the above technical solution, through the cooperation between the pushing ring 407 and the positioning pin 408, when the positioning pin 408 is inserted into the inside of the through hole 305, the pushing ring 407 will resist the driving gear 402 and push the driving gear 402 toward the direction of the servo motor 401, so that the driving gear 402 moves through the sliding groove on the surface of the rotating shaft through the sliding buckle, and then the meshing between the driving gear 402 and the gears composed of the first clamping gear 301 and the second clamping gear 302 is released, and at the same time, the driving gear 402 is meshed with the driven gear 403, so that the driving gear 402 can drive the driven gear 403 to rotate, and then the driven gear 403 can drive the transmission gear 209 to rotate, so that the transmission gear 209 drives the screw rod 206 to rotate, and then the semi-circular arc limit plate 201 moves to both sides on the surface of the screw rod 206, so that the first clamping gear 301 inside the semi-circular arc limit plate 201 The first clamping gear 301 and the second clamping gear 302 are exposed, and then the first clamping gear 301 and the second clamping gear 302 will be opened to both sides due to the influence of factors such as gravity, so that the torsion bar spring 10 can be taken out therefrom, so that when the device is in use, the through hole 305 can be positioned by the positioning pin 408, so that when the first clamping gear 301 and the second clamping gear 302 are rotated, they will definitely wait until the through hole 305 rotates to the position of the positioning pin 408, and then the positioning pin 408 is inserted into the interior of the through hole 305 to stop the first clamping gear 301 and the second clamping gear 302 from rotating, thereby preventing the first clamping gear 301 and the second clamping gear 302 from being unable to rotate and open to both sides, and at the same time positioning the position of the torsion bar spring 10, so as to facilitate the positioning of the position of the torsion bar spring 10 that needs to be processed, thereby preventing the two ends of the torsion bar spring 10 from being asymmetrical during processing.

[0038] Furthermore, the limiting mechanism 2 includes a semi-circular limiting disk 201, a limiting groove 202, a movable annular groove 203, a sliding groove 204, a semi-trapezoidal notch 205, a screw rod 206, a transmission belt 207, a transmission rod 208 and a transmission gear 209. The semi-circular limiting disk 201 is movably mounted on the outer surface of the first clamping gear 301 and the second clamping gear 302. The interior of the semi-circular limiting disk 201 is provided with a limiting groove 202.

[0039] Furthermore, the clamping mechanism 3 also includes a semi-dome block 303, a fixed rod 304, a gear inner groove 306 and a compression spring 307. The outer surfaces of both sides of the first clamping gear 301 and the second clamping gear 302 are fixedly installed with fixed rods 304, the inner surfaces of the first clamping gear 301 and the second clamping gear 302 are provided with gear inner grooves 306, and compression springs 307 are movably installed inside the gear inner grooves 306. The semi-dome block 303 is movably installed inside the gear inner grooves 306, one end of the semi-dome block 303 is in contact with the surface of the compression spring 307, and the other end of the semi-dome block 303 is in contact with the surface of the torsion bar spring 10.

[0040] Furthermore, the transmission mechanism 4 also includes a servo motor 401, a fixed block 406 and a pushing ring 407. A rotating shaft is movably installed on the inner side of the driving gear 402, and the rear side of the rotating shaft is connected to the servo motor 401 through a coupling. The top and bottom ends of the sliding table 405 are fixedly installed with fixed blocks 406, and a pushing ring 407 is fixedly installed on one side of the fixed block 406 close to the positioning pin 408, and the pushing ring 407 is in contact with the surface of the driving gear 402.

[0041] By adopting the above technical solution, through the setting of the pushing ring 407, the device can make the pushing ring 407 push the driving gear 402 when the positioning pin 408 is inserted into the through hole 305, thereby disengaging the driving gear 402 from the gear composed of the first clamping gear 301 and the second clamping gear 302, and at the same time making the driving gear 402 mesh with the driven gear 403, thereby transmitting the semicircular arc limit plate 201.

[0042] Further, the material changing mechanism 5 includes a fixed frame 501, a connecting rod 502, a T-shaped slide 503, a T-shaped slider 504, a fan-shaped arc plate 505, an angle limit plate 506, a rotating plate 507, a positioning plate 508 and an inclined plate 509. The fixed frame 501 is movably installed at the outer position of the outer surface of the torsion bar spring 10, and the interior of the fixed frame 501 is provided with a T-shaped slide 503, and the interior of the T-shaped slide 503 is movably installed with a T-shaped slider 504, and the outer end of the T-shaped slider 504 is fixedly connected to the connecting rod 502, and the outer end of the connecting rod 502 A fan-shaped arc plate 505 is fixedly installed, and an angle limit plate 506 is fixedly installed on the surface of the fan-shaped arc plate 505. One end of the fan-shaped arc plate 505 with the angle limit plate 506 is connected to a rotating plate 507 through an axis. Two positioning plates 508 are fixedly installed on the other side of the outer surface of the torsion bar spring 10, and an inclined plate 509 is fixedly installed on the top of the positioning plate 508. The surface of the rotating plate 507 is in contact with the surface of the positioning plate 508, and the outer diameter of the rotating plate 507 is larger than the distance between the fan-shaped arc plate 505 and the positioning plate 508.

[0043] By adopting the above technical solution, through the cooperation of the T-shaped slider 504 and the fan-shaped arc plate 505, when the device is in use, after the semicircular arc limit plate 201 moves to both sides, the linear motor drives the T-shaped slider 504 to rise inside the T-shaped slide groove 503, so that the T-shaped slider 504 drives the connecting rod 502 and the fan-shaped arc plate 505 to rise. At this time, the surface of the fan-shaped arc plate 505 fits with the surface of the torsion bar spring 10 to move the torsion bar spring 10 upward. When the torsion bar spring 10 moves upward, it will hit the first clamping gear 301 and the first clamping gear 302. The upper end surface position of the inner side of the second clamping gear 302 further applies force to the first clamping gear 301 and the second clamping gear 302, so that the first clamping gear 301 and the second clamping gear 302 can be opened to both sides, preventing the first clamping gear 301 and the second clamping gear 302 from being unable to be opened directly by gravity. At the same time, when the fan-shaped arc plate 505 rises, it will drive the rotating plate 507 to rise. Since the outer diameter of the rotating plate 507 is larger than the distance between the fan-shaped arc plate 505 and the positioning plate 508, the surface of the rotating plate 507 will maintain contact with the torsion bar The spring 10 rises in a tangential state until the rotating plate 507 moves to the upper position of the inclined plate 509. At this time, the rotating plate 507 will rotate downward due to gravity, so that the rotating plate 507 rotates to the position where the positioning plate 508 and the inclined plate 509 are connected. At this time, the torsion bar spring 10 will roll along the surface of the rotating plate 507 and the surface of the inclined plate 509 to the inside of the collecting box 9, thereby completing the unloading of the torsion bar spring 10. At this time, the T-shaped slider 504 will drive the fan-shaped arc plate 505 to descend, and at the same time add another torsion bar spring 10 to the inside through the feed box 1. The unprocessed torsion bar spring 10 will fall downward and fall on the surface of the fan-shaped arc plate 505. When the fan-shaped arc plate 505 descends, the bottom end surface of the rotating plate 507 contacts the connection position of the positioning plate 508 and the inclined plate 509 and is exerted with force, thereby causing the rotating plate 507 to rotate upward until it fits with the surface of the unprocessed torsion bar spring 10 and makes its surface tangent to the torsion bar spring 10, thereby preventing the torsion bar spring 10 from rolling into the inside of the collecting box 9. When the T-shaped slider 504 returns to its original position, the torsion bar spring 10 can be processed by the processing table 6.

[0044] Furthermore, a feed box 1 is provided at the top of the positioning plate 508 , a collection box 9 is fixedly mounted on the outer surface of the positioning plate 508 via a connecting rod, and a surface of the inclined plate 509 is inclined toward the inside of the collection box 9 .

[0045] By adopting the above technical solution and setting the inclined plate 509 , the torsion bar spring 10 can roll along the surface of the rotating plate 507 and the surface of the inclined plate 509 into the inside of the collecting box 9 , which facilitates the unloading of the torsion bar spring 10 .

[0046] Furthermore, a slide buckle is fixedly installed on the inner side of the driving gear 402, and two slide grooves are provided on the outer surface of the rotating shaft inside the driving gear 402. The slide buckles are movably inserted into the inside of the slide grooves, the driven gear 403 and the transmission gear 209 are meshed and connected, and the positioning pins 408 are movably inserted into the inside of the through hole 305.

[0047] Furthermore, the fixing rods 304 are movably inserted into the movable annular groove 203 and the sliding groove 204 .

[0048] By adopting the above-mentioned technical scheme, through the cooperation of the movable annular groove 203 and the sliding groove 204, the first clamping gear 301 and the second clamping gear 302 can be supported inside the limiting groove 202 through the fixing rod 304, so as to prevent the first clamping gear 301 and the second clamping gear 302 from falling off. At the same time, when it is necessary to open the semi-circular arc limiting plate 201 to both sides, the fixing rod 304 can be moved out of the limiting groove 202 through the sliding groove 204, so as to separate the semi-circular arc limiting plate 201 from the first clamping gear 301 and the second clamping gear 302.

[0049] Furthermore, both ends of the torsion bar spring 10 are movably inserted into the interior of the processing table 6 .

[0050] By adopting the above technical solution, both ends of the torsion bar spring 10 are processed by the processing table 6 .

[0051] Furthermore, a linear motor is disposed on the outer side of the fixing frame 501 , and the T-shaped sliding blocks 504 are driven by the linear motor to move up and down at a uniform speed inside the T-shaped sliding groove 503 .

[0052] Working principle: When in use, through the cooperation of the first clamping gear 301 and the second clamping gear 302, the device can insert the positioning pin 408 into the interior of the through hole 305, so that the first clamping gear 301 and the second clamping gear 302 can be rotated to both sides with the positioning pin 408 as the axis, thereby opening the middle so that the torsion bar spring 10 can be placed in the first clamping gear 301 and the second clamping gear 302, thereby clamping the torsion bar spring 10, and through the cooperation of the semi-dome block 303 and the compression spring 307, when the first clamping gear 301 and the second clamping gear 302 clamp the torsion bar spring 10, the semi-dome block 303 can be ejected outward due to the elastic potential energy of the compression spring 307, so that the semi-dome block 303 is tightly attached to the surface of the torsion bar spring 10, thereby tightening the torsion bar spring 10 to prevent the torsion bar spring 10 from loosening and shaking, and the device can clamp torsion bar springs 10 of different sizes.

[0053] By pushing the cooperation between the circular ring 407 and the positioning pin 408, when the positioning pin 408 is inserted into the inside of the through hole 305, the circular ring 407 will push against the driving gear 402 and push the driving gear 402 toward the direction of the servo motor 401, so that the driving gear 402 moves through the sliding groove on the surface of the rotating shaft through the sliding buckle, thereby releasing the meshing between the driving gear 402 and the gears composed of the first clamping gear 301 and the second clamping gear 302, and at the same time, the driving gear 402 is meshed with the driven gear 403, so that the driving gear 402 can drive the driven gear 403 to rotate, and then the driven gear 403 can drive the transmission gear 209 to rotate, so that the transmission gear 209 drives the screw rod 206 to rotate, and then the semi-circular arc limit plate 201 moves to both sides on the surface of the screw rod 206, so that the first clamping gear 301 and the second clamping gear 302 inside the semi-circular arc limit plate 201 are released. The gear 302 is exposed, and then the first clamping gear 301 and the second clamping gear 302 will open to both sides due to the influence of factors such as gravity, so that the torsion bar spring 10 can be taken out therefrom, so that when the device is in use, the through hole 305 can be positioned by the positioning pin 408, so that when the first clamping gear 301 and the second clamping gear 302 rotate, they will definitely wait until the through hole 305 rotates to the position of the positioning pin 408, and then the positioning pin 408 is inserted into the inside of the through hole 305 to stop the first clamping gear 301 and the second clamping gear 302 from rotating, thereby preventing the first clamping gear 301 and the second clamping gear 302 from being unable to rotate and open to both sides, and at the same time positioning the position of the torsion bar spring 10, which is convenient for positioning the position of the torsion bar spring 10 that needs to be processed, thereby preventing the two ends of the torsion bar spring 10 from being asymmetrical during processing.

[0054] Through the cooperation of the T-shaped slider 504 and the fan-shaped arc plate 505, when the device is in use, after the semicircular arc limit plate 201 moves to both sides, the linear motor drives the T-shaped slider 504 to rise inside the T-shaped slide groove 503, so that the T-shaped slider 504 drives the connecting rod 502 and the fan-shaped arc plate 505 to rise. At this time, the surface of the fan-shaped arc plate 505 fits with the surface of the torsion bar spring 10 to move the torsion bar spring 10 upward. When the torsion bar spring 10 moves upward, it will hit the first clamping gear 301 and the second clamping gear 302. The upper end surface position of the side is further applied to the first clamping gear 301 and the second clamping gear 302, so that the first clamping gear 301 and the second clamping gear 302 can be opened to both sides, preventing the first clamping gear 301 and the second clamping gear 302 from being unable to be opened directly by gravity. At the same time, when the fan-shaped arc plate 505 rises, it will drive the rotating plate 507 to rise. Since the outer diameter of the rotating plate 507 is larger than the distance between the fan-shaped arc plate 505 and the positioning plate 508, the surface of the rotating plate 507 will remain tangent to the torsion bar spring 10 The rotating plate 507 rises until it moves to the upper position of the inclined plate 509. At this time, the rotating plate 507 will rotate downward due to gravity, so that the rotating plate 507 rotates to the position where the positioning plate 508 and the inclined plate 509 are connected. At this time, the torsion bar spring 10 will roll along the surface of the rotating plate 507 and the surface of the inclined plate 509 to the inside of the collecting box 9, thereby completing the unloading of the torsion bar spring 10. At this time, the T-shaped slider 504 will drive the fan-shaped arc plate 505 to descend, and at the same time, another torsion bar spring 10 will be added to the inside through the feed box 1. The processed torsion bar spring 10 will fall downward and land on the surface of the fan-shaped arc plate 505. When the fan-shaped arc plate 505 descends, the bottom end surface of the rotating plate 507 contacts the connection position of the positioning plate 508 and the inclined plate 509 and is exerted with force, thereby causing the rotating plate 507 to rotate upward until it fits with the surface of the unprocessed torsion bar spring 10 and makes its surface tangent to the torsion bar spring 10, thereby preventing the torsion bar spring 10 from rolling into the collection box 9. When the T-shaped slider 504 returns to its original position, the torsion bar spring 10 can be processed by the processing table 6.
