Description

Technical Field

[0001] This application relates to the field of spring processing, and in particular to a spring locking device. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under external force and returns to its original shape after the force is removed. Patent CN206912149U discloses a spring compressor, including a base, a spring inlet on the base, a rotating mechanism, a spring compression mechanism, and a spring outlet. The spring compressor also has a first station, a second station, and a third station. The rotating mechanism includes at least three spring loading forks that cycle between the first, second, and third stations. Since the spring is loaded onto the spring loading forks at the first station through the spring inlet, the spring compression mechanism compresses the spring as the spring loading forks transport it from the first station to the second station. After compression, the spring loading forks rotate and transport the spring from the second station to the third station for discharge. Therefore, compression and discharge can be completed simply by placing the spring into the spring inlet, making the spring compression process simple, time-saving, and labor-saving.

[0003] In the process of realizing the above application, the inventors discovered that the technology has at least the following problems: during the compression process, the spring is only compressed once, and after the single compression is completed, the spring returns to its original position. It is impossible to compress the spring for a long time, and the compression quality of the spring cannot be guaranteed. Summary of the Invention

[0004] To ensure the quality of spring compression, this application provides a spring locking device.

[0005] The spring locking device provided in this application adopts the following technical solution: A spring locking device includes a body, on which a locking device for locking a spring is detachably connected. The locking device includes a support rod, a locking part detachably connected to the support rod, and a blocking block, wherein the diameter of the blocking block is larger than the diameter of the locking part. The machine body is slidably provided with a motion chuck for driving the locking device to move, and the machine body is rotatably provided with a separation chuck for separating the locking part from the support rod; The machine body is provided with a feeding part, and a feeding plate is slidably provided at the end of the feeding part. A lifting groove is provided on the feeding part, and the feeding plate is slidably connected to the inner wall of the lifting groove. A lifting platform is fixed on the inner wall of the lifting groove to facilitate the lifting and lowering of the feeding plate. A material feeding frame for placing locking devices is provided on the ground. A first sorting part is fixed to the back of the material feeding frame. A first sorting groove is provided on the first sorting part. The width of the first sorting groove is greater than the diameter of the locking part and less than the diameter of the blocking block. A second sorting part is provided at the bottom of the first sorting part. The second sorting section has a second sorting groove on its end face. The diameter of the second sorting groove is larger than the diameter of the support rod but smaller than the diameter of the locking part. Push rods are slidably provided at the ends of both the first sorting section and the second sorting section.

[0006] By adopting the above technical solution, the spring is locked on the machine body. During the locking process, the support rod passes through the inside of the spring, and both ends of the spring abut against the blocking block and the end face of the locking part, respectively. The locking device corresponds one-to-one with the spring, thus ensuring that the spring is locked on the locking device for a long time and guaranteeing the locking quality of the spring. The moving chuck drives the locking device to slide on the machine body, and the separating chuck can act on the locking part and separate the locking part from the support rod, facilitating the spring installation process. After locking, the locking device is detached from the machine body under the action of the feeding part and the feeding plate, allowing for operation. The process is relatively convenient; the locking device in the feeding frame is transferred to the first sorting section. Since the width of the sorting groove is greater than the diameter of the locking part but less than the diameter of the blocking block, the locking device is vertically set under the action of gravity. At the same time, the locking device without the blocking block will fall to the second sorting section. The diameter of the second sorting groove is greater than the diameter of the support rod but less than the diameter of the locking part. The locking device that falls to the second sorting section is vertically set under the action of gravity, and the locking part is in contact with the end face of the second sorting section. The push rod pushes the locking device to move toward the ends of the first and second sorting sections.

[0007] Optionally, a loading platform is slidably disposed within the feeding frame. The loading platform has a stepped cross-section and its upper end is inclined.

[0008] By adopting the above technical solution, the loading platform is stepped and can slide inside the unloading frame, which facilitates the transportation of the locking device inside the unloading frame.

[0009] Optionally, both the first sorting section and the second sorting section have a fixed turning section at their ends. The turning section includes a turntable rotatably disposed at the end of the first sorting section or the second sorting section. Several lifting blocks are fixed on the side wall of the turntable. Both the first sorting section and the second sorting section have a rotatably disposed pushing block at their tops. The pushing block rotates only in the direction close to the turntable. The bottom of the pushing block has a pushing guide surface.

[0010] By adopting the above technical solution, the rotating turntable drives the lifting block to rotate, the lifting block abuts against the bottom of the support rod, and pushes the support rod to move. Under the restriction of the pushing block and the pushing guide surface, the locking device disengages from the first sorting section and the second sorting section.

[0011] Optionally, a receiving plate is fixed to the end of the turntable, an adjusting push block is slidably arranged at the bottom of the receiving plate, a transfer plate is fixed to the side wall of the receiving plate, and a plurality of adjusting discs are rotatably connected to the transfer plate, with a plurality of adjusting grooves opened on the adjusting discs.

[0012] By adopting the above technical solution, the locking device that is detached from the first sorting section and the second sorting section is transferred to the receiving plate, and under the action of the adjusting push block, it is pushed to the end of the receiving plate and transferred to the transfer plate. Then, under the action of the adjusting plate and the adjusting groove, the locking device gradually detaches from the receiving plate.

[0013] Optionally, a storage section is provided at the bottom of the second sorting section, and the transfer plate extends to the storage section. The storage section includes a receiving section and a transport section. The receiving section is located at the bottom of the second sorting section, and the transport section is connected to the receiving section, with the transport state of the transport section being set in a step-by-step manner.

[0014] By adopting the above technical solution, only the locking device of the support rod falls from the second sorting section to the receiving section, the locking device on the transfer plate is transferred to the transportation section, and is then gripped and transferred to the machine body by the robot arm.

[0015] In summary, this application includes at least one of the following beneficial technical effects of the spring locking device: 1. The spring is locked on the machine body. During the locking process, the support rod passes through the inside of the spring, and the two ends of the spring abut against the blocking block and the end face of the locking part, respectively. The locking device corresponds to the spring one by one, so the spring can be locked on the locking device for a long time, thus ensuring the locking quality of the spring. 2. The spring can be heat-treated in the locked state to extend its lifespan. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] First aspect: This application discloses a spring locking device. (Refer to...) Figure 1 , Figure 2 and Figure 3 The spring locking device includes a body 1, which is placed on the ground. The body 1 is equipped with several processing elements for locking springs. A locking device 2 is detachably connected to the body 1. The locking device 2 is used to lock the spring. The locking device 2 includes a support rod 3, a locking part 4, and a blocking block 5. The support rod 3 is cylindrical. The locking part 4 and the blocking block 5 are detachably connected to the side wall of the support rod 3. The support rod 3, the locking part 4, and the blocking block 5 are coaxially arranged. During use, the support rod 3 passes through the inside of the spring. Under the action of the body 1, the locking part 4 and the blocking block 5 are installed on the side wall of the support rod 3, and the two ends of the spring abut against the end face of the blocking block 5 and the end face of the locking part 4, respectively, thereby completing the spring locking process.

[0025] Reference Figure 1 , Figure 2 and Figure 3A motion motor is bolted to the machine body 1. A motion screw is fixed to the shaft of the motion motor, and a motion chuck 6 is fitted onto the motion screw. A track is fixed to the machine body 1 to restrict the movement direction of the motion chuck 6. When the motion motor starts, it drives the motion screw to rotate. Since there is a threaded connection between the motion screw and the motion chuck 6, the motion screw can drive the motion chuck 6 to move along the axis of the motion screw on the machine body 1. The motion chuck 6 is a three-jaw chuck, which can clamp the support rod 3. The three-jaw chuck holds the support rod 3... After clamping, the movement is driven by the moving screw, thereby driving the locking device 2 to move on the machine body 1; a separation chuck 7 is rotatably connected to the machine body 1 via a rotating shaft. The separation chuck 7 is used to clamp the locking part 4 and separate the locking part 4 from the support rod 3. During the process of the moving chuck 6 driving the support rod 3 to move, the support rod 3 moves into the separation chuck 7, the separation chuck 7 clamps and rotates the locking part 4, so that the support rod 3 is separated from the locking part 4, and the spring sleeve is set on the support rod 3; the locking part 4 includes a first connecting block 31. The first connecting block 31 has a polygonal outer wall portion and another portion that passes through the second connecting block 32. The portion inside the second connecting block 32 has several openings and is threadedly connected to the inner wall of the second connecting block 32. By adjusting the position between the second connecting block 32 and the first connecting block 31, the first connecting block 31 can be fixed or separated from the support rod 3. A finding plate 33 is slidably provided on the machine body 1. During the rotation of the locking device 2 driven by the separating chuck 7, the finding plate 33 abuts against the polygonal portion, and the separating chuck 7 stops rotating. A positioning rod 34 is slidably provided on the machine body 1, and a positioning groove 35 is provided on the positioning rod 34. The polygonal portion of the first connecting block 31 passes through the positioning groove 35. At this time, the separating chuck 7 drives the second connecting block 32 to rotate, so that the support rod 3 can be pulled out from the first connecting block 31. At the same time, the end of the second connecting block 32 can abut against the end of the positioning rod 34, reducing the possibility that the support rod 3 will drive the locking part 4 to move during the movement.

[0026] Reference Figure 1 , Figure 4 and Figure 5A feeding frame 8 is provided on the ground. The feeding frame 8 is used to place the raw materials of the locking device 2, which facilitates the feeding process of the locking device 2. A feeding platform 9 is slidably installed inside the feeding frame 8. The feeding platform 9 has a stepped cross-section and can slide vertically inside the feeding frame 8. One side wall of the feeding platform 9 is attached to the inside of the feeding frame 8. A positioning platform 38 is fixed inside the feeding frame 8. The positioning platform 38 is stepped and offset from the feeding platform 9. A discharging part 27 is fixed inside the feeding frame 8. The discharging part 27 is plate-shaped and inclined. After the locking device 2 is placed on the unloading part 27, it moves toward the loading platform 9 under the action of gravity. The unloading part 27 is flush with the stepped surface at the end of the loading platform 9. The bottom of the feeding frame 8 is fixed with a drive motor 36 by bolts. The shaft of the drive motor 36 is keyed with a cam 37. The side wall of the cam 37 abuts against the bottom of the loading platform 9. The drive motor 36 rotates and drives the cam 37 to rotate, thereby driving the loading platform 9 to move vertically in the feeding frame 8. The upper end of the loading platform 9 is inclined to facilitate the transportation of the locking device 2 to the top of the loading platform 9.

[0027] Reference Figure 1 , Figure 4 and Figure 5 The back of the feeding frame 8 is fixed with a first sorting section 10 by bolts. The first sorting section 10 is plate-shaped and has a first sorting groove 11. The length of the first sorting section 10 and the first sorting groove 11 are the same. The first sorting section 10 gradually moves closer to the ground from the position away from the first sorting groove 11 towards the position closer to the first sorting groove 11. After the locking device 2 is released from the feeding table 9, it moves to the first sorting section 10. Since the upper end face of the first sorting section 10 is inclined, the locking device 2 will roll to the first sorting groove 11. The diameter of the blocking block 5 is larger than the diameter of the locking part 4, and the diameter of the locking part 4 is larger than the diameter of the support rod 3. The width of the first sorting groove 11 is larger than the diameter of the locking part 4 and smaller than the diameter of the blocking block 5. Therefore, when the locking device 2 rolls to the first sorting groove 11, it rotates under the action of gravity. At the same time, the blocking block 5 abuts against the end face of the first sorting section 10, which facilitates the adjustment of the direction of the locking device 2.

[0028] Reference Figure 1 , Figure 4 and Figure 5The bottom of the first sorting section 10 is provided with a second sorting section 12. The second sorting section 12 is plate-shaped and has a second sorting groove 13. The second sorting groove 13 passes through the second sorting section 12 vertically. The upper end face of the second sorting section 12 is inclined and gradually approaches the ground from the position close to the second sorting groove 13. The width of the second sorting groove 13 is greater than the diameter of the support rod 3 and less than the diameter of the locking part 4. If there is no blocking block 5 in the locking device 2 on the first sorting section 10, it will fall from the first sorting section 10 to the second sorting section 12. Since the end face of the second sorting section 12 is inclined, under the action of gravity, the locking part 4 in the locking device 2 abuts against the end face of the second sorting section 12 and the locking device 2 is vertically arranged.

[0029] Reference Figure 1 , Figure 4 and Figure 5Both the first sorting section 10 and the second sorting section 12 have push rods slidably mounted at their ends. The push rods 14 pass through the first sorting groove 11 and the second sorting groove 13. Both the first sorting section 10 and the second sorting section 12 have push cylinders fixed to their ends. The piston rod of the push cylinder is fixed to the push rod 14, and when the push cylinder is activated, it pushes the push rod 14 to move along its length within the first sorting groove 11 or the second sorting groove 13, thereby pushing and converging the locking devices 2 within the first and second sorting grooves 11 and 13. Both the first sorting section 10 and the second sorting section 12 are provided with a turning part 15. The turning part 15 includes a turntable 16 rotatably mounted at the end of the first sorting section 10 or the second sorting section 12 via a rotating shaft. The axis of the turntable 16 is perpendicular to the length direction of the first sorting section 10. Several lifting blocks 17 are integrally formed on the side wall of the turntable 16, and the lifting blocks 17 are "L" shaped. The turntable 16 is placed at the bottom of the locking device 2. A rotating motor for driving the turntable 16 to rotate is provided on the ground. The rotating motor shaft is keyed to the turntable 16. The rotation of the 6-axis causes the lifting block 17 to rotate, and the lifting block 17 abuts against the bottom of the support rod 3, pushing the support rod 3 to move vertically upward. Both the first sorting section 10 and the second sorting section 12 have brackets fixed to their side walls. A pushing block 18 is rotatably mounted on the bracket via a rotating shaft. The pushing block 18 at the first sorting section 10 is positioned above the first sorting section 10, and the pushing block 18 at the second sorting section 12 is positioned above the second sorting section 12. The pushing block 18 can only rotate in the direction closest to the turntable 16, and a pushing guide is provided at the bottom of the pushing block 18. The guide surface 19 is inclined. When the support rod 3 moves upward under the drive of the turntable 16 and the lifting block 17, its top abuts against the guide surface 19 on the push block 18. Under the action of the guide surface 19, the support rod 3 tilts towards the turntable 16. A receiving plate 20 is provided at the other end of the turntable 16. The turntable 16 can drive the locking device 2 to transfer to the receiving plate 20. The side wall of the receiving plate 20 is fixed with an anti-deviation plate by bolts. The anti-deviation plate reduces the possibility of the locking device 2 disengaging from the turntable 16.

[0030] Reference Figure 1 , Figure 4 and Figure 5A receiving electric cylinder is fixed to the bottom of the receiving plate 20 by bolts. An adjusting push block 21 is fixed to the piston rod of the receiving electric cylinder. The adjusting push block 21 can push the locking device 2 on the receiving plate 20 to the end of the receiving plate 20. A high-speed camera is fixed to the end of the receiving plate 20 at the end of the first sorting section 10 by bolts. The high-speed camera can detect the shape of the locking device 2 on the receiving plate 20. When it is detected that there is no locking part 4 on the support rod 3, the robot arm clamps the individual locking part 4 and installs it on the support rod 3. At the same time, the robot arm installs the blocking block 5 on the locking device 2 at the end of the receiving plate 20 of each second sorting section 12. After the installation is completed, the locking device 2 of the receiving plate 20 at the end of the second sorting section 12 is reversed so that the locking device 2 at the end of the first sorting section 10 and the locking device 2 at the end of the second sorting section 12 are facing the same direction.

[0031] Reference Figure 1 , Figure 4 and Figure 5 A transfer plate 22 is bolted to the side wall of the receiving plate 20. The transfer plate 22 is inclined, and several adjusting discs 23 are rotatably connected to both sides of the transfer plate 22 via rotating shafts. Several adjusting grooves are opened on the side wall of the adjusting discs 23, and the adjusting grooves are evenly distributed around the axis of the adjusting discs 23. After the locking device 2 is transferred to the transfer plate 22, the support rod 3 passes through the adjusting groove, and the rotation of the adjusting discs 23 drives the locking device 2 to move. A storage section 24 is provided at the bottom of the second sorting section 12, and the transfer plate 22 extends to the storage section 24. The storage section 24 includes a receiving section 25 and a transport section 26. The receiving section 25 is hollow and is located at the bottom of the second sorting section 12. The receiving section 25 is used to receive and store the support. The support rod 3, whose side wall is not fixed to the locking part 4 and the blocking block 5, falls into the receiving part 25 after passing through the first sorting groove 11 and the second sorting groove 13, which facilitates its unified collection and processing; the transport part 26 is placed on the side wall of the receiving part 25. The transport part 26 is in the shape of a conveyor belt and has several transport grooves. The transport grooves are used to pass through the support rod 3, which can transport the locking device 2 while reducing the possibility of the locking device 2 shifting position; the receiving part 25 is fixed to the side wall by bolts with a transport motor. The transport motor is used to drive the transport part 26 to rotate. At the same time, the transport motor is a stepper motor, so that the transport state of the transport part 26 is set in steps, which makes it easy for the robot to clamp the locking device 2 and transfer it to the machine body 1.

[0032] Reference Figure 1 , Figure 2 and Figure 6The machine body 1 is provided with a feeding part 27, which is plate-shaped and fixed to the bottom of the moving chuck 6 by bolts. When the moving chuck 6 moves, it can drive the feeding part 27 to move synchronously. A feeding plate 28 is slidably provided at the end of the feeding part 27 away from the moving chuck 6. A lifting groove 29 is provided on the feeding part 27. The feeding plate 28 passes through the lifting groove 29 and can slide along the length of the lifting groove 29. That is, the feeding plate 28 is slidably connected to the inner wall of the lifting groove 29. The length of the lifting groove 29 is parallel to the movement direction of the moving chuck 6. A lifting platform 30 is fixed to the inner wall of the lifting groove 29 by integral molding. The top of the lifting platform 30 is inclined. The feeding plate 28 and the lifting platform 30 are connected. During the movement of the unloading plate 28, due to the inclined top of the lifting platform 30, the unloading plate 28 gradually extends out of the lifting groove 29 and contacts the locking part 4, pushing the locking part 4 to separate the locking device 2 from the moving chuck 6. The inner end of the lifting groove 29 is fixed with a lifting electric cylinder by bolts. The unloading plate 28 is fitted with a moving sleeve. The piston rod of the lifting electric cylinder is fixed to the end of the moving sleeve. The unloading plate 28 can slide vertically inside the moving sleeve. The side wall of the unloading plate 28 is integrally formed with two lifting rods. The two lifting rods extend to the outside of the moving sleeve and contact the end face of the lifting platform 30 to facilitate the movement of the unloading plate 28. In the initial state, the unloading plate 28 is placed inside the lifting groove 29.

[0033] Second aspect This embodiment discloses a processing technology applicable to the above-mentioned spring locking device, including the following steps: a. Place the locking part 4 on the loading platform 9; b. The first sorting section 10 and the second sorting section 12 sort the locking devices 2 and place them into the machine body 1 by the robotic arm; c. The locking device 2 locks the spring on the body 1 and maintains the locked state; d. Under the action of the feeding section 27 and the feeding plate 28, the locking device 2 disengages from the machine body 1; e. The spring and locking device 2 in the locked state are subjected to heat treatment.

[0034] The implementation principle of the spring locking device and processing technology in this application embodiment is as follows: The locking device 2 is placed on the loading platform 9. The loading platform 9 drives the locking device 2 to move to the first sorting section 10. The first sorting section 10 performs preliminary sorting of the locking devices 2, that is, the locking devices 2 without the blocking block 5 installed on the support rod 3 fall to the second sorting section 12, and the rest remain in the first sorting section 10. The second sorting section 12 performs secondary sorting of the locking devices 2, and only the locking devices 2 on the support rod 3 fall to the storage section 24, and the rest remain in the second sorting section 12. The push rod 14 pushes the locking devices 2 in the first sorting section 10 and the second sorting section 12 to move, so that they move to the storage section 24. At the ends of the first sorting section 10 and the second sorting section 12, the locking device 2 is transferred to the receiving plate 20 under the drive of the turntable 16. The locking device 2 on the receiving plate 20 is rotated under the drive of the robot, so that the locking device 2 on the receiving plate 20 at the ends of the first sorting section 10 and the second sorting section 12 faces the same direction. After the rotation is completed, the locking device 2 is transported to the transport section 26 and transferred to the machine body 1 under the grip of the robot, and the spring is locked on the machine body 1. After locking, under the action of the unloading section 27 and the unloading plate 28, the locking device 2 is disengaged from the machine body 1. Then, the locking device 2 and the spring are kept in a compressed state for heat treatment, which improves the service life of the spring.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
