DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] The slide rail 11 is an electric slide rail, and the movable base 12 is driven to move on the slide rail 11 by a stepper motor. The three-jaw chuck assembly 14 can be used to stably clamp one end of the worm workpiece, and the turning assembly 13 can be used to process the worm teeth on the worm workpiece. It is worth noting that the turning machine body 1, the slide rail 11, the movable base 12, the turning assembly 13 and the three-jaw chuck assembly 14 are all electrically controlled, and the specific turning structure of the worm workpiece is the prior art, so no further description is given.

[0047] See also Figure 3-7 The top of the movable base 12 is fixedly provided with a fixed base 2, one end of the fixed base 2 is provided with an ejector cavity 21 inwardly, the ejector cavity 21 is adapted to the movable base 3, the ejector assembly 31, and the guide rail 32, the rear of the ejector cavity 21 is connected with a spring cavity 22, a first spring 221 is installed outwardly in the spring cavity 22, and the other end of the first spring 221 is connected to the movable base 3. Through the provision of the first spring 221, the movable base 3 can be pushed outward, so that the ejector assembly 31 and the guide rail 32 can be synchronously pushed out of the ejector cavity 21 through the movable base 3.

[0048] Among them, an adjustment cavity 23 is opened in the fixed base 2 behind the spring cavity 22, and the connecting rod 33 is adapted to be movable in the adjustment cavity 23. The end of the connecting rod 33 extends from the top of the fixed base 2 through the adjustment cavity 23 and is fixedly connected to the push plate 331. In addition, a guide rod is also provided in the adjustment cavity 23, and the connecting rod 33 is guided to move by the guide rod, which can further increase the moving stability of the movable seat 3 and the push plate 331.

[0049] See also Figure 5-7 The top of the fixed base 2 is provided with an assembly slot 25, the loading box 6 is adapted to be installed on the top of the assembly slot 25, and the bottom of the loading box 6 is adapted to be provided with a bottom cavity corresponding to the assembly slot 25. Through the adaptation setting between the bottom cavity and the assembly slot 25, the worm workpiece can be pushed out from the assembly slot 25. In addition, the assembly box is provided with a variety of sizes, and the user can freely replace the assembly box according to the number of worm workpieces to be filled.

[0050] The push plate 331 is movable in the assembly groove 25, and a second spring 241 is fixedly connected to the rear of the push plate 331. The other end of the second spring 241 is connected to the spring seat 24, and the spring seat 24 is fixedly mounted on the fixed base 2. The push plate 331 can be pushed by the second spring 241, so that the worm workpiece in the assembly groove 25 can be pushed out by the push plate 331.

[0051] See also Figure 5-9 The fixed base 2 is provided with side cavities 211 on both sides of the ejector cavity 21 , and first guide columns 212 are fixedly arranged in the side cavities 211 . The side plates 34 extend from the side cavities 211 and are guided and moved by the first guide columns 212 .

[0052] The top of the movable base 12 is located on both sides of the fixed base 2 and is vertically fixed with a plurality of second guide columns 26, and the movable plate 4 is guided and moved by the second guide columns 26. The top of the second guide columns 26 is provided with an anti-dropping member to prevent the movable plate 4 from falling off the second guide columns 26.

[0053] The top of the side plate 34 is fixed with a slot 341 downward, the outer side of the side plate 34 is fixed with a guide plate 35, and the outer side of the guide plate 35 is provided with a guide groove 351. The movable plate 4 is provided with a guide member 40 corresponding to the guide groove 351. Through the adaptation between the guide groove 351 and the guide member 40, when the side plate 34 moves horizontally through the movable seat 3, the movable plate 4 can be driven to move vertically. In addition, the guide groove 351 is tilted as a whole, and the top is a horizontal surface, which can prevent the movable plate 4 from falling due to gravity when it is at the top.

[0054] See also Figure 3-4, 8-11, the movable plate 4 is fixedly provided with a support plate 41, and the support plates 41 on both sides are located in front of the fixed base 2, so that the worm workpiece pushed out from the assembly groove 25 can be moved to the top of the support plates 41 on both sides after being guided by the guide rail 32.

[0055] The ends of the support plate 41 are provided with movable cavities 411 inwardly, and the third springs 412 are installed outwardly in the movable cavities 411, and the other ends of the third springs 412 are connected to the movable support plate 42. The movable support plate 42 can be pushed outward by the arrangement of the third springs 412. The length of the support plate 41 can be extended by the arrangement of the movable support plate 42 to prevent the worm workpiece from extending from the end of the support plate 41.

[0056] A plurality of guide blocks are fixedly arranged on the inner wall of the movable cavity 411, and guide rails are adapted to the corresponding knife blocks on the movable support plate 42. The adaption between the guide blocks and the guide rails can not only guide the movable support plate 42, but also prevent the movable support plate 42 from falling off from the movable cavity 411.

[0057] See also Figure 12-15 , a sub-plate 421 is fixedly provided at the end of the movable support plate 42, and a magnetic block cavity 422 is provided on each of the sub-plates 421, and an upper magnetic part 423 is vertically movably provided inside the magnetic block cavity 422. A lower support seat 424 is fixedly provided at the bottom of the sub-plate 421, and a lower magnetic part 431 is vertically movably provided between the lower support seats 424 on both sides, and the lower magnetic part 431 and the upper magnetic part 423 repel each other. This allows the upper magnetic part 423 to move upwards by the repulsive magnetic force when the lower magnetic part 431 moves upwards. In this way, the upper magnetic part 423 can move upwards between the sub-plates on both sides, so as to prevent the worm workpiece from falling off the support plate 41 after being pushed out.

[0058] In addition, guide rods are vertically fixed inside the magnetic block cavity 422. Through the setting of the guide rods, the upper magnetic part 423 can be guided to improve the stability of the upper magnetic part 423 during the movement.

[0059] The lower support seat 424 is provided with a vertical cavity 425, and the ends of the bent plates 43 extend into the lower support seat 424 through the vertical cavity 425 and are connected to the lower magnetic member 431. A plurality of lower guide seats 413 are fixedly provided at the bottom of the support plate 41, and the bent plates 43 pass through the lower guide seats 413. Guide rods are vertically fixedly provided in the lower guide seats 413, and the bent plates 43 are guided and moved vertically by the guide rods, so that the lower magnetic member 431 can be driven to move synchronously by the vertical movement of the bent plates 43.

[0060] See also Figure 3-4, 15-17, both sides of the fixed base 2 are fixedly provided with fixed blocks 27, and the fixed blocks 27 are vertically provided with through holes, and both ends of the lifting frame 5 pass through the through holes. The bottom of the fixed blocks 27 is downwardly installed with fourth springs 51, and the bottom of the fourth springs 51 is connected to the wedge-shaped clamping member 52. Through the setting of the elastic force of the fourth spring 51, the wedge-shaped clamping member 52 can be pushed downward synchronously together with the lifting frame 5, so that the wedge-shaped clamping member 52 can be stably clamped in the clamping groove 341. And the right-angle end of the lifting frame 5 is located above the fixed block 27, so that the lifting frame 5 will not move too far downward. And through the setting of the through holes on the fixed blocks 27 on both sides, the vertical movement of the lifting frame 5 can also be guided.

[0061] A transverse groove 53 is vertically provided in the lifting frame 5, and the bending plate 43 is inserted in the transverse groove 53. A magnetic transverse column 54 is fixedly provided in each transverse groove 53, and a magnetic vertical cavity 432 is provided corresponding to the magnetic transverse column 54 on the bending plate 43, and a magnetic surface that is adapted to attract the magnetic transverse column 54 is provided at the bottom of the magnetic vertical cavity 432. In this way, the bending plate 43 can be driven to continue to move upward for a distance through the attraction force between the magnetic transverse column 54 and the magnetic surface at the bottom of the magnetic vertical cavity 432.

[0062] In this embodiment, a slide rail 11 is fixedly provided on the turning machine body 1, and a movable base 12 is movably provided on the slide rail 11. The fixed base 2 and the worm workpiece can be driven to move by the movement of the movable base 12 on the slide rail 11. Thus, one end of the worm workpiece can be moved to the three-jaw chuck assembly 14, so that one end of the worm workpiece can be fixed by the three-jaw chuck assembly 14, and the worm workpiece can be driven to rotate, and the other end of the worm workpiece can be supported by the ejector assembly 31, so that the worm teeth on the worm workpiece can be processed by the turning assembly 13.

[0063] Furthermore, when the user needs to process the worm workpiece, he only needs to pull the lifting frame 5 upwards. At this time, the fourth spring 51 is stretched, and the wedge-shaped clamping member 52 and the lifting frame 5 move upwards synchronously, and the wedge-shaped clamping member 52 can leave from above the clamping slot 341, so that the clamping device between the wedge-shaped clamping member 52 and the clamping slot 341 can be released.

[0064] At this time, the wedge-shaped clamping member 52 no longer clamps the side plate 34, and the movable seat 3 can automatically move outwards by the elastic force of the first spring 221, thereby driving the ejector assembly 31 and the guide rail 32 to synchronously extend from the ejector cavity 21. In addition, during the outward movement of the movable seat 3, the side plates 34 and the guide plates 35 on both sides also move synchronously with the movable seat 3, thereby driving the guide member 40 to move in the guide groove 351 through the movement of the guide groove 351, so as to drive the movable plates 4 on both sides to move upward, thereby driving the support plate 41 and the movable support plate 42 to move upward synchronously, so that the support plates 41 and the movable support plate 42 on both sides can move to the top and align with the three-jaw chuck assembly 14, so as to ensure that the worm workpiece on the subsequent support plate 41 and the movable support plate 42 can be adapted to be inserted into the three-jaw chuck assembly 14 and clamped.

[0065] It is worth noting that, since a flat groove is provided at the top of the guide groove 351, when the movable plate 4 is at the highest point, the guide member 40 can be located in the flat groove in the guide groove 351, thereby preventing the movable plate 4 from automatically moving downward by its own gravity.

[0066] Furthermore, since the push plate 331 is fixedly connected to the movable seat 3 through the connecting rod 33, when the lifting frame 5 moves upward, the movable seat 3 is no longer fixed, and thus the push plate 331 is no longer fixed. At this time, the movable seat 3 can be pushed out by the first spring 221, and the push plate 331 can be pushed out synchronously by the second spring 241, so that the worm workpiece in the assembly groove 25 can be pushed out by the thrust of the push plate 331. At this time, the worm workpiece can be guided by the guide rail 32 and fall onto the supporting plates 41 that are pushed upward on both sides, so that the worm workpiece can be quickly assembled.

[0067] It is worth noting that, since the assembly groove 25 is adapted to the worm workpiece, and the combined thrust of the first spring 221 and the second spring 241 can quickly push out the movable seat 3 and the push plate 331, the push plate 331 can exert sufficient force on the worm workpiece, and can push out the worm workpiece. And by setting the guide rail 32, the worm workpiece can be guided, so as to ensure that the worm workpiece can stably fall on the support plate 41.

[0068] Furthermore, when the lifting frame 5 moves upward, it can drive the movable plates 4, the support plates 41 and the movable support plates 42 on both sides to move upward through the movable seat 3. In this way, the bending plate 43 can move upward synchronously with the support plates 41 and the movable support plates 42, and the magnetic vertical cavity 432 can move upward synchronously at this time, so that the distance between the magnetic surface at the bottom of the magnetic vertical cavity 432 and the magnetic horizontal column 54 can be reduced. When the bending plate 43 moves to the top, the distance between the magnetic surface at the bottom of the magnetic vertical cavity 432 and the magnetic horizontal column 54 is reduced to the limit value of the magnetic attraction force. At this time, the magnetic surface at the bottom of the magnetic vertical cavity 432 can move upward through the magnetic attraction force between the magnetic horizontal column 54, so that the entire bending plate 43 can be driven to move upward synchronously through the magnetic attraction force.

[0069] When the bending plate 43 moves upward, it can drive the lower magnetic part 431 to move upward synchronously, so that the upper magnetic part 423 can be lifted upward by the repulsive magnetic force between the lower magnetic part 431 and the upper magnetic part 423. At this time, the upper magnetic part 423 is moved upward in the magnetic block cavity 422 by the repulsive magnetic force, so that the upper magnetic part 423 can limit the end of the worm workpiece synchronously to prevent the worm workpiece pushed onto the support plate 41 from falling off the movable support plate 42 due to excessive impact force. And when the lifting frame 5 is released, it will automatically move downward due to gravity, so that the upper magnetic part 423 can also move downward synchronously.

[0070] It is worth noting that, since the magnetic attraction between the magnetic surface at the bottom of the magnetic vertical cavity 432 and the magnetic horizontal column 54 is greater than the sum of the gravity of the bending plate 43 + the repulsive magnetic force between the lower magnetic member 431 and the upper magnetic member 423, it can drive the bending plate 43 to move upward. And when the movable plate 4 moves downward, it can drive the bending plate 43 to overcome the magnetic attraction between the magnetic surface at the bottom of the magnetic vertical cavity 432 and the magnetic horizontal column 54 and move downward synchronously.

[0071] In summary, when the lifting frame 5 is pulled upward, it can release the clamping of the movable seat 3, so that the movable seat 3 and the push plate 331 can be pushed out by the elastic force in the first spring 221 and the second spring 241, so that the worm workpiece in the assembly groove 25 can be ejected by the push plate 331. And the movable plates 4 on both sides can be driven to lift upward through the movable seat 3, thereby driving the support plate 41, the movable support plate 42 and the bending plate 43 to lift upward to achieve the positioning support of the worm workpiece. Then, the bending plate 43 can be driven to move upward by the attraction between the magnetic cross column 54 and the magnetic surface at the bottom of the magnetic vertical cavity 432, so that the upper magnetic part 423 can be pushed upward by the repulsive force between the lower magnetic part 431 and the upper magnetic part 423, so that the upper magnetic part 423 can prevent the worm workpiece pushed into the support plate 41 from falling off the movable support plate 42 due to excessive impact force. In this way, the assembly of the worm workpiece can be achieved.

[0072] Furthermore, the user only needs to control the movable base 12 to move toward the three-jaw chuck assembly 14 through the control panel. Since the auxiliary plate 421 on the movable support plate 42 first contacts the three-jaw chuck assembly 14, during the movement of the movable base 12, the movable support plate 42 can be pushed into the movable cavity 411 through the auxiliary plate 421, and the third spring 412 is compressed at this time. In this way, one end of the worm workpiece can be pushed into the three-jaw chuck assembly 14 through the movement of the movable base 12, so that one end of the worm workpiece can be clamped by the three-jaw chuck assembly 14.

[0073] Then the movable base 12 continues to move until the ejector assembly 31 on the movable seat 3 contacts and presses the other end of the worm workpiece, so that the ejector assembly 31 and the movable seat 3 can be pushed into the ejector cavity 21 through the worm workpiece. Thus, the first spring 221 and the second spring 241 can be compressed by the movable seat 3 and the push plate 331, and in the process of the movable seat 3 and the side plate 34 moving, the wedge-shaped clamp 52 can be automatically clamped in the clamping groove 341 through the setting of the fourth spring 51, so that the movable seat 3 can be fixed through the adaptation clamping between the wedge-shaped clamp 52 and the clamping groove 341 to ensure that the first spring 221 and the second spring 241 can be in a compressed state. And when the push plate 331 moves, it can leave the assembly groove 25 at the bottom of the loading box 6, and the worm workpiece in the loading box 6 can automatically fall into the assembly groove 25.

[0074] And when the movable seat 3 and the side plate 34 move, the movable plates 4 on both sides can automatically move downward through the adaptation setting between the guide groove 351 and the guide member 40, thereby driving the support plates 41, the movable support plates 42 and the bending plates 43 on both sides to move downward synchronously, so as to prevent the support plates 41 and the movable support plates 42 from affecting the turning of the worm workpiece.

[0075] It is worth noting that when the ejector assembly 31 pushes against the worm workpiece, the back of the movable seat 3 is in direct contact with the ejector cavity 21, and the first spring 221 is completely compressed in the spring cavity 22. This allows the ejector assembly 31 to be in rigid contact with the worm workpiece, rather than in flexible contact with the worm workpiece through the first spring 221, so as to improve the positioning effect of the worm workpiece.

[0076] In summary, when the movable base 12 moves toward the three-jaw chuck assembly 14, the movable support plate 42 can automatically retract into the movable cavity 411 through the third spring 412 after contacting the three-jaw chuck assembly 14. In this way, the worm workpiece can be inserted into the three-jaw chuck assembly 14 and clamped. Then, during the continued movement of the movable base 12, the other end of the worm workpiece can be limited by the ejector assembly 31, and the movable seat 3 moves backward through the ejector assembly 31, thereby driving the support plates 41 and the movable support plate 42 on both sides to move downward. In this way, the turning of the worm workpiece can be achieved through the turning assembly 13. And the push plate 331 also moves backward synchronously to reset, so that the worm workpiece can be pushed out again in the next cycle.

[0077] After turning is completed, the movable support plate 42 can be automatically reset by the third spring 412. At this time, the user only needs to take out the worm workpiece after turning and pull the lifting frame 5 upward again to push the next worm workpiece out to the support plate 41, so that the user can load and clamp the worm workpiece.

[0078] In the present invention, when the user pulls the lifting frame 5 upward, the movable seat 3 and the push plate 331 can be automatically moved by the elastic force of the first spring 221 and the second spring 241, so that the support plate 41 can be lifted up and the worm workpiece can be ejected onto the support plate 41. Through the movement of the movable base 12, one end of the worm workpiece can be clamped on the three-jaw chuck assembly 14, and when the ejector assembly 31 positions the other end of the worm workpiece, the movable seat 3 and the push plate 331 can be pushed backward to compress the first spring 221 and the second spring 241 again, so that the movable seat 3 and the push plate 331 continue to work in the next cycle. This assembly and positioning method for the worm workpiece is simple and convenient, does not require the user to perform too many complicated operations, and improves the processing efficiency of the worm.

[0079] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
