Abstract
Description
Technical Field
[0001] This application relates to the field of workpiece clamping technology, specifically to a spinning mechanism. Background Technology
[0002] In CNC machining, rotary cylinders are typically used to clamp products. To machine the clamped position, the current solution is to use a solenoid valve to control the rotary cylinder's rotation and positioning. Once the clamped position is machined, the solenoid valve re-controls the rotary cylinder to clamp the product. However, the response time of the solenoid valve is too long. To match the solenoid valve's response time, the CNC machine tool needs to be set to a lower feed rate, thus affecting the product machining efficiency. Summary of the Invention
[0003] In view of the above, it is necessary to propose a spinning mechanism that can shorten the response time and quickly press or release the product to improve work efficiency.
[0004] This application provides a spinning mechanism, which includes a base, a drive assembly, and a spinning component. The drive assembly includes a drive member and a rotary cam. The drive member is connected to the base. The rotary cam is rotatably connected to the base and connected to the drive member, and is used to rotate under the drive of the drive member. The spinning component includes a guide member, a push-pull member, and a spinning component. The guide member is connected to the base and disposed on one side of the drive member, and is arranged along the axial direction of the rotary cam. One end of the push-pull member is slidably connected to the guide member, and the other end of the push-pull member is slidably connected to the rotary cam. The push-pull member is used to move along the guide member when the rotary cam rotates. The spinning component is movably connected to the guide member and connected to the push-pull member. The end of the spinning component away from the guide member is used to press against the product. The spinning component rotates under the guidance of the guide member while following the movement of the push-pull member, so as to rotate away from or towards the product.
[0005] In the aforementioned spinning mechanism, the drive unit drives a rotary cam to rotate, which in turn moves a push-pull component and causes it to slide along a guide. When the push-pull component moves, it drives the spinning component to move as well. Simultaneously, the spinning component rotates relative to the guide under the action of the guide, thus performing a rotational motion or rotating closer to the product. Since the spinning assembly is directly connected to the drive unit, and no other structure is required between them, the spinning component can begin moving immediately upon activation of the drive unit. This shortens the response time of the spinning component and improves the working efficiency of the spinning mechanism.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0071] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0072] Please see Figure 1 This application provides a spinning mechanism 100 in some embodiments. The spinning mechanism 100 of this embodiment is used to press the product during machining so that the machining tool can process the product, and to quickly release the product during machining to avoid the tool, so that the tool can process the position pressed by the spinning mechanism 100.
[0073] For ease of understanding, Figure 1 A three-dimensional coordinate system was established, with the X-axis, Y-axis and Z-axis perpendicular to each other and the directions of each axis as shown in the figure.
[0074] The spinning mechanism 100 includes a base 10, a drive assembly 20, and a spinning assembly 30. The base 10 includes a first plate 11, a second plate 12, and a vertical plate 13. The first plate 11 is longer than the second plate 12, and the first plate 11 and the second plate 12 are arranged parallel to each other. The two ends of the vertical plate 13 are respectively connected to the first plate 11 and the second plate 12. The first plate 11, the second plate 12, and the vertical plate 13 are approximately U-shaped. The drive assembly 20 and the spinning assembly 30 are spaced apart on the base 10, and the base 10 supports the drive assembly 20 and the spinning assembly 30.
[0075] The drive assembly 20 includes a drive member 21, a brake member 22, and a rotary cam 23. The drive member 21 is connected to the first plate 11 of the base 10 and is located on the side of the first plate 11 opposite to the second plate 12. The rotary cam 23 is connected between the first plate 11 and the second plate 12 on the base 10, and the rotary cam 23 is rotatable relative to the first plate 11 and the second plate 12. The drive member 21 is connected to the rotary cam 23, and the rotary cam 23 rotates under the drive of the drive member 21.
[0076] The brake element 22 is connected to the second plate 12 on the base 10. The brake element 22 is used to brake the rotary cam 23 so as to achieve precise control of the rotary cam 23.
[0077] Please see Figure 1 and Figure 2The spinning assembly 30 includes a guide 31, a push-pull member 32, and a spinning member 33. The guide 31 is disposed on the side of the first plate 11 opposite to the second plate 12, and is located on one side of the drive member 21. The guide 31 has a circular guide hole 311, which is a stepped hole, and extends along the axis of the rotary cam 23. That is, the axis O1 of the guide hole 311 is parallel to the axis O2 of the rotary cam 23 and is both arranged along the Z-axis. The guide 31 guides the push-pull member 32 so that the push-pull member 32 can move along the Z-axis, and guides the spinning member 33 so that the spinning member 33 can rotate relative to the guide 31.
[0078] One end of the push-pull member 32 is connected to the guide hole 311 of the guide member 31, and the other end of the push-pull member 32 is slidably connected to the rotary cam 23. When the rotary cam 23 rotates, the push-pull member 32 and the rotary cam 23 will slide relative to each other and slide along the guide member 31 at the same time.
[0079] The spun part 33 is inserted into the guide part 31 and connected to the push-pull part 32. When the push-pull part 32 moves along the guide part 31, the spun part 33 will move together with the push-pull part 32 and rotate under the guidance of the guide part 31.
[0080] When it is necessary to press the product, the drive component 21 drives the rotary cam 23 to rotate. At this time, the push-pull component 32 slides relative to the rotary cam 23, and the push-pull component 32 slides along the guide component 31 in the negative direction of the Z-axis under the action of the rotary cam 23. At the same time, the spinning component 33 slides together with the push-pull component 32 in the negative direction of the Z-axis. During the sliding process of the spinning component 33, the guide component 31 guides the spinning component 33, thereby causing the spinning component 33 to rotate. At this time, the spinning component 33 rotates and descends to press the product.
[0081] When the cutting tool needs to be avoided during product processing, the drive component 21 drives the rotary cam 23 to rotate. The rotary cam 23 drives the push-pull component 32 to slide along the guide component 31 in the positive Z-axis direction. At the same time, the spinning component 33 moves together with the push-pull component 32 in the positive Z-axis direction. During the sliding process of the spinning component 33, the guide component 31 guides the spinning component 33, causing the spinning component 33 to rotate. At this time, the spinning component 33 rotates and rises to release the product, so that the cutting tool can process the pressed position of the spinning component 33.
[0082] Please see Figure 2 In this embodiment, the driving component 21 includes a driving body 211 and a transmission body 212. The driving body 211 can be a servo motor, and the driving body 211 is connected to the side of the first plate 11 opposite to the second plate 12.
[0083] The transmission body 212 can be an electromagnetic clutch. The transmission body 212 includes a fixed part 2121, a rotating part 2122, and a connecting part 2123. The fixed part 2121 is mounted on the side of the first plate 11 facing the second plate 12. The rotating part 2122 is rotatably connected to the fixed part 2121. The output end of the drive body 211 is connected to the rotating part 2122, allowing the rotating part 2122 to rotate relative to the fixed part 2121 under the drive of the drive body 211. The connecting part 2123 is disposed opposite to the rotating part 2122. Specifically, the connecting part 2123 is connected to the side of the rotating cam 23 facing the first plate 11.
[0084] When the transmission body 212 is working, it is energized. At this time, the rotating part 2122 engages with the connecting part 2123. When the rotating part 2122 and the connecting part 2123 are attracted together, the driving body 211 drives the rotating part 2122 to rotate, which in turn drives the rotating cam 23 to rotate as well. When the rotating cam 23 rotates, it can cause the spinning part 33 to rotate upward or downward.
[0085] When the transmission body 212 is de-energized, the drive body 211 is rotating. However, because the rotating part 2122 and the connecting part 2123 are not engaged, the drive body 211 cannot drive the rotating cam 23 to rotate. By setting a transmission body 212 between the rotating cam 23 and the drive body 211, the drive body 211 can remain rotating without being shut down. When it is necessary to drive the spinning part 33, the transmission body 212 can be energized. Since the drive body 211 does not need to be shut down, the start-up time and output acceleration time of the drive body 211 are saved. This allows the drive body 211 to quickly drive the spinning part 33 to move at the instant the transmission body 212 is energized and engaged, thereby saving the response time of the drive body 211 and improving the processing efficiency of the product.
[0086] The braking element 22 can also be an electromagnetic clutch. The braking element 22 includes a mounting body 221, an adsorption body 222, and a braking body 223. The mounting body 221 is mounted on the side of the second plate 12 facing the first plate 11 on the base 10, and the mounting body 221 is arranged opposite to the transmission body 212. The adsorption body 222 is connected to the mounting body 221, and the braking body 223 is connected to the side of the rotating cam 23 facing the adsorption body 222. The adsorption body 222 is used to engage the braking body 223 when the braking element 22 is energized. When the adsorption body 222 and the braking body 223 come into contact, the rotating cam 23 stops rotating.
[0087] During the rotational ascent or descent of the spinning component 33, the transmission body 212 and the brake 22 need to work together as follows: First, the transmission body 212 is energized, while the brake 22 remains de-energized. At this time, the drive body 211 drives the rotary cam 23 to rotate via the transmission body 212. When the rotary cam 23 rotates, it can drive the spinning component 33 to rotate upward or downward. After the spinning component 33 needs to complete the rotational ascent or descent, the transmission body 212 is de-energized, and the brake 22 is energized. At this time, the adsorption body 222 engages with the brake body 223. When the adsorption body 222 and the brake body 223 come into contact, the rotary cam 23 stops rotating. By precisely controlling the rotation of the rotary cam 23 under the action of the brake 22, the spinning component 33 can be accurately stopped at the predetermined position.
[0088] The rotary cam 23 includes a cam body 231 and a connecting shaft 232. The cam body 231 is cylindrical, and the adsorption body 222 and the rotating part 2122 are connected to both sides of the cam body 231. The connecting shaft 232 passes through the cam body 231, and the cam body 231 can rotate relative to the connecting shaft 232. One end of the connecting shaft 232 passes through the cam body 231 and is connected to the rotating part 2122. With this configuration, when the rotating part 2122 and the connecting part 2123 are not engaged, the drive body 211 drives the rotating part 2122 to rotate. At this time, the rotating part 2122 drives the connecting shaft 232 to rotate together, while the cam body 231 does not rotate. When the rotating part 2122 and the connecting part 2123 are engaged, the drive body 211 drives the rotating part 2122 to rotate, and the rotating part 2122 drives the connecting shaft 232 and the cam body 231 to rotate together.
[0089] Please see Figure 2 and Figure 3 The cam body 231 has a track groove 233 on its circumference. One end of the push-pull member 32 is connected to the track groove 233. When the cam body 231 is rotating, the push-pull member 32 can slide along the track groove 233. The track groove 233 includes two connecting grooves 2331 and two transition grooves 2332. The extension direction of the transition grooves 2332 is perpendicular to the axial direction of the cam body 231. The two transition grooves 2332 are evenly distributed on the circumference of the cam body 231, and the distance between one transition groove 2332 and the drive member 21 is greater than the distance between the other transition groove 2332 and the drive member 21. That is, the two transition grooves 2332 are arranged at different heights in the Z-axis direction. Both connecting grooves 2331 are inclined. The two ends of the two connecting grooves 2331 are connected to the two transition grooves 2332 respectively. The two connecting grooves 2331 and the two transition grooves 2332 form a closed track groove 233.
[0090] When the spinning member 33 is in the rotational rising stage, during the process of the drive body 211 driving the rotating cam 23 to rotate, the sliding direction of the push-pull member 32 in the track groove 233 is from the lower transition groove 2332 to the higher transition groove 2332. When the push-pull member 32 slides along the connecting groove 2331, since the connecting groove 2331 is inclined, the push-pull member 32 slides along the guide member 31 under the drive of the rotating cam 23. At the same time, the push-pull member 32 drives the spinning member 33 to achieve the rotational rising movement.
[0091] When the spinning member 33 is in the rotation and descent stage, during the process of the drive body 211 driving the rotating cam 23 to rotate, the sliding direction of the push-pull member 32 in the track groove 233 is from the higher transition groove 2332 to the lower transition groove 2332. When the push-pull member 32 slides along the connecting groove 2331, the push-pull member 32 slides along the guide member 31 under the drive of the rotating cam 23. At the same time, the push-pull member 32 drives the spinning member 33 to achieve the rotation and descent movement.
[0092] Because the transmission body 212 and the brake 22 have a response time during use, for example, when the transmission body 212 is de-energized and the brake 22 is just beginning to be energized, the rotary cam 23 will still rotate. By providing a transition groove 2332 at the end of the connecting groove 2331, even if the rotary cam 23 continues to rotate at this time, the push-pull member 32 will not rise or fall, thereby preventing the spinning member 33 from continuing to move.
[0093] Furthermore, when the number of connecting grooves 2331 is set to one, during the rotational descent of the spinning part 33 after it rotates upward, the direction of the drive body 211 needs to be changed. However, by setting the track groove 233 into a closed shape, the operator does not need to change the direction of the drive body 211. That is, the drive body 211 remains in a state of continuous rotation. The push-pull part 32 only needs to make a cyclical movement along the track groove 233 to realize the rotational upward and downward movements of the spinning part 33 in sequence, thus eliminating the need for frequent start-stop to change the direction of the drive body 211.
[0094] The push-pull component 32 includes a push-pull body 321 and a follower part 322. One end of the push-pull body 321 passes through the first plate 11 and slides through the guide member 31, and the push-pull body 321 is connected to the spinning member 33. The follower part 322 is connected to the end of the push-pull body 321 away from the guide member 31, and the end of the follower part 322 is slidably connected in the track groove 233. When the cam body 231 rotates, the follower part 322 slides relative to the rotating cam 23 along the track groove 233 and drives the push-pull body 321 to slide along the guide member 31.
[0095] Please see Figure 1 and Figure 2The push-pull body 321 includes a push-pull rod 3211 and a sliding part 3212. The base 10 also includes a bearing seat 14, which is connected to the side of the first plate 11 facing the second plate 12. The bearing seat 14 has a mounting groove 141, in which a linear bearing is installed. The push-pull rod 3211 passes through the mounting groove 141 and is slidably connected to the linear bearing, which guides the push-pull rod 3211. One end of the push-pull rod 3211 passes through the first plate 11 and is connected to the sliding part 3212, while the other end is connected to the follower part 322. The push-pull rod 3211 and the follower part 322 are arranged perpendicularly.
[0096] When the push-pull rod 3211 slides along the Z-axis, the follower 322 also slides along the Z-axis. To avoid interference between the follower 322 and the bearing housing 14, a clearance hole 142 is provided on the side of the bearing housing 14. The clearance hole 142 communicates with the mounting groove 141, allowing the follower 322 to pass through and slide within the track groove 233. When the rotary cam 23 rotates, the follower 322 slides along the track groove 233 while simultaneously sliding in the Z-axis direction. Due to the presence of the clearance hole 142, the bearing housing 14 does not obstruct the movement of the follower 322, thus allowing the follower 322 to move smoothly.
[0097] The sliding part 3212 is slidably disposed within the guide hole 311, and is rotatably connected to the end of the push-pull rod 3211 that extends into the guide member 31. When the follower part 322 drives the push-pull rod 3211 to move along the Z-axis, the push-pull rod 3211 will drive the sliding part 3212 to slide along the guide hole 311. During this process, the guide hole 311 guides the sliding part 3212. At the same time, the sliding part 3212 is connected to the spinning member 33, and the sliding part 3212 drives the spinning member 33 to move.
[0098] The spinning member 33 includes a rotating body 331, a pressing part 332, and an elastic part 333. The rotating body 331 passes through the guide hole 311 of the guide member 31, and one end of the rotating body 331 located in the guide hole 311 is connected to the sliding part 3212 of the push-pull member 32. The rotating body 331 can rotate relative to the push-pull rod 3211 under the action of the sliding part 3212. Specifically, the rotating body 331 includes a guide rod 3311 and a crossbar 3312. The guide rod 3311 is a cylindrical rod, which allows the guide rod 3311 to rotate relative to the guide member 31. One end of the guide rod 3311 is connected to the sliding part 3212, and the other end of the guide rod 3311 is connected to the crossbar 3312. The guide rod 3311 and the crossbar 3312 are L-shaped.
[0099] The pressing part 332 includes a pressing block 3321 and a pressing cover 3322. The pressing block 3321 is slidably connected to the end of the crossbar 3312 away from the guide rod 3311. The elastic part 333 can be a spring, and there are multiple elastic parts 333. One end of the multiple elastic parts 333 abuts against the pressing block 3321. The pressing cover 3322 is connected to the crossbar 3312 and covers the multiple elastic parts 333. At this time, the other end of the multiple elastic parts 333 abuts against the pressing cover 3322. When the pressing block 3321 presses against the product, the pressing block 3321 maintains elastic contact with the product under the elastic action of the multiple elastic parts 333, so that the pressing block 3321 will not damage the product when pressing it, thus achieving the purpose of protecting the product.
[0100] Please see Figure 2 and Figure 4 To allow the rotating body 331 to rotate relative to the guide member 31, a guide portion 312 is protruding from the guide member 31, and the guide portion 312 is located inside the guide hole 311. A guide groove 3313 is formed on the side of the guide rod 3311 of the rotating body 331. When the guide rod 3311 is connected to the guide member 31, the guide portion 312 slides into the guide groove 3313. The guide groove 3313 includes two straight grooves 3314 and one inclined groove 3315. The two straight grooves 3314 extend in the same direction as the axial direction of the guide rod 3311. The two straight grooves 3314 are spaced apart along both the circumference and axial direction of the guide rod 3311. The two ends of the inclined groove 3315 are connected to the two straight grooves 3314 respectively. The two straight grooves 3314 and the inclined groove 3315 are approximately Z-shaped.
[0101] When the push-pull rod 3211 slides along the Z-axis under the drive of the rotary cam 23, the push-pull rod 3211 drives the sliding part 3212 to slide along the guide member 31. At this time, the sliding part 3212 drives the guide rod 3311 to slide along the guide member 31. At the same time, the guide part 312 will slide along the guide groove 3313. For example, when the guide rod 3311 moves upward, the sliding direction of the guide part 312 is from the straight groove 3314 with a higher height to the straight groove 3314 with a lower height. When the guide part 312 slides in the inclined groove 3315, since the guide member 31 is fixed as a whole, while the guide rod 3311 is movable, the guide part 312 will cause the guide rod 3311 to rotate. At this time, the guide rod 3311 moves upward under the drive of the sliding part 3212, and also rotates under the action of the guide part 312. Since the crossbar 3312 is connected to the guide rod 3311, the crossbar 3312 carries the pressure block 3321 to rotate and rise away from the product, thereby releasing the product to avoid the cutting tool, so that the cutting tool can process the position where the pressure block 3321 is pressed.
[0102] When the guide rod 3311 descends, the guide part 312 slides from the lower straight groove 3314 to the higher straight groove 3314. When the guide part 312 slides within the inclined groove 3315, since the guide member 31 is fixed while the guide rod 3311 is movable, the guide part 312 causes the guide rod 3311 to rotate. At this time, the guide rod 3311 descends under the drive of the sliding part 3212 and also rotates under the action of the guide part 312. Therefore, the crossbar 3312 carries the pressure block 3321 and rotates down to press the product, thereby achieving the purpose of fixing the product.
[0103] Furthermore, the straight groove 3314 and the guide portion 312 work together to limit the guide rod 3311, preventing it from rotating arbitrarily. For example, when the pressure block 3321 presses against the product, the guide portion 312 is positioned within the higher straight groove 3314. The two walls of the straight groove 3314 abut against the guide portion 312, thus limiting the guide rod 3311. Under the restriction of the guide portion 312, the guide rod 3311 will not rotate, thereby preventing the pressure block 3321 from sliding against the product and making the pressure block 3321 more securely fixed to the product.
[0104] Please see Figure 4 and Figure 5 To achieve precise control over the rotation angle of the guide rod 3311, the spinning mechanism 100 also includes a sensing element 40 and a sensor 50. In this embodiment, there are two sensing elements 40 and two sensors 50, each corresponding to a specific element. The sensor 50 is electrically connected to an external controller. Both sensors 50 are connected to the guide member 31, and the two sensing elements 40 are connected at intervals to the guide rod 3311 of the spinning member 33. The sensing element 40 can be a protrusion or groove on the guide rod 3311, and it rotates along with the guide rod 3311. During the upward rotation of the guide rod 3311, i.e., when the spinning member 33 releases the product, if one of the sensors 50 detects the corresponding sensing element 40, the controller receives the signal from that sensor 50 and controls the transmission body 212 to be de-energized, while simultaneously energizing the brake member 22. When the transmission body 212 is de-energized, the rotating cam 23 loses its rotational power, and the brake member 22 brakes the rotating cam 23, thereby stopping its rotation. During the process of the guide rod 3311 rotating and descending, that is, when the spinning part 33 presses the product, and another sensor 50 detects the corresponding sensing part 40, the controller receives the signal and controls the transmission body 212 to be de-energized, while simultaneously energizing the brake part 22, thereby causing the rotating cam 23 to stop rotating.
[0105] The working process of the spinning mechanism 100 provided in this embodiment is roughly as follows:
[0106] The drive body 211 needs to remain in a rotating state. When it is necessary to press the product, the transmission body 212 remains energized, the brake 22 remains de-energized, and the rotating part 2122 and the connecting part 2123 are engaged together. At this time, the drive body 211 can drive the cam body 231 on the rotating cam 23 to rotate together. When the cam body 231 rotates, the follower part 322 on the push-pull member 32 slides along the track groove 233. The follower part 322 slides from the higher transition groove 2332 to the lower transition groove 2332, and at the same time drives the... The push-pull body 321 moves downward along the Z-axis. During the movement of the push-pull body 321, the sliding part 3212 on the push-pull body 321 will drive the guide rod 3311 of the spinning part 33 to descend together. The guide part 312 on the guide member 31 slides in the guide groove 3313 on the guide rod 3311. The guide part 312 enters from the straight groove 3314 with a lower height to the straight groove 3314 with a higher height, causing the guide rod 3311 to rotate. As a result, the guide rod 3311 carries the pressure block 3321 and rotates downward, causing the pressure block 3321 to press against the product.
[0107] When the pressure block 3321 needs to move away from the tool, the transmission body 212 is energized and the brake 22 is de-energized. At this time, the drive body 211 drives the cam body 231 on the rotary cam 23 to rotate together. When the cam body 231 rotates, the follower part 322 on the push-pull member 32 slides from the lower transition groove 2332 to the higher transition groove 2332, and at the same time drives the push-pull body 321 to move upward along the Z-axis. During the movement of the push-pull body 321, the sliding part 3212 on the push-pull body 321 will drive the guide rod 3311 of the spinning member 33 to rise together, and the guide rod 31... The guide part 312 slides in the guide groove 3313 on the guide rod 3311. The guide part 312 enters from the higher straight groove 3314 to the lower straight groove 3314, causing the guide rod 3311 to rotate. This causes the guide rod 3311 to rotate and rise with the pressure block 3321, and the pressure block 3321 to move out of position. When the sensor 50 detects the sensing element 40, the transmission body 212 is de-energized, the braking element 22 is energized, the adsorption body 222 engages the braking body 223, and the braking element 22 brakes the rotating cam 23, causing the rotating cam 23 to stop rotating, thereby stopping the guide rod 3311 from rotating.
