Description

Technical Field

[0001] This application relates to the field of spiral spring processing technology, and in particular to an assembly device for a spiral spring and a cover. Background Technology

[0002] As a highly efficient energy storage element, spiral springs are currently widely used in automotive clutches, household appliances, industrial brakes, and various valve devices. Their core characteristic is the use of the strong torsional stiffness formed by winding steel plates to achieve the transmission and buffering of large torques within a limited space.

[0003] Reference Figure 1 The coil spring is installed inside a circular cover. Both ends of the spring are machined into specific hooks, which are annealed and have relatively poor elasticity. The inside of the cover has a locking tab for engaging one of the hooks. During assembly, the worker pre-compresses the spring, reducing its outer diameter, and then engages the hooks with the locking tabs and precisely inserts it into the cover. After the pressure is released, the spring expands due to its elasticity, and the hooks at both ends firmly engage with the corresponding grooves or holes on the cover.

[0004] Regarding the above assembly method, the inventors believe that manual pre-compression and placement are highly dependent on the operator's experience, which can easily lead to incorrect posture of the coil spring and difficulty in aligning the hook, resulting in low overall assembly efficiency. Summary of the Invention

[0005] To improve the assembly efficiency of the coil spring and the cover, this application provides an assembly device for the coil spring and the cover.

[0006] The assembly equipment for coil springs and covers provided in this application adopts the following technical solution: An assembly device for a coil spring and a cover includes a fixed support, an assembly base inclinedly disposed on the fixed support, a decoupling mechanism disposed on the assembly base, a pushing mechanism for ejecting the assembled finished product, a guiding adjustment mechanism slidably mounted on the assembly base, and a clamping mechanism for pressing the coil spring. The anti-roll mechanism includes a positioning post disposed on the assembly base plate, an anti-roll post rotatably mounted on the assembly base plate, and an anti-roll drive component for driving the anti-roll post to rotate. The anti-roll post has a hook groove for inserting a hook at one end of a spiral spring. The pushing mechanism includes a pushing disc corresponding to the anti-coiling column and a pushing drive component that drives the pushing disc to move along the axis of the anti-coiling column. The pushing disc and the positioning column are arranged alternately.

[0007] By adopting the above technical solutions, the inclined assembly substrate facilitates the assembly of the coil spring and the cover. The anti-coiling mechanism, through the positioning of the positioning column and the rotation of the anti-coiling column in conjunction with the hook groove, can perform anti-coiling operation on the spiral spring. The pushing mechanism's pushing plate and pushing drive can push out the assembled finished product. The guiding adjustment mechanism can adjust the coil spring assembly guide, and the pressing mechanism can press the spiral spring, avoiding the problems of incorrect posture and difficulty in hook alignment caused by manual pre-compression and placement, thus improving the assembly efficiency of the coil spring and the cover.

[0008] Optionally, it also includes a feeding mechanism for feeding spiral springs. The feeding mechanism includes a vibratory feeder, a feeding column that is inclinedly arranged on the vibratory feeder and corresponding to the positioning column, and a first transmission structure arranged at the output end of the pusher drive. The end of the feeding column is provided with a positioning block that limits the contact with the spiral springs. The spiral springs are fed to the positioning column one by one through the first transmission structure.

[0009] By adopting the above technical solution, the automatic feeding of spiral springs is achieved using a feeding mechanism, avoiding the problem of manual feeding relying on operator experience and improving the feeding efficiency of spiral springs. The vibrating feeder vibrates and sorts the spiral springs and conveys them to the feeding column. The positioning block at the end of the feeding column limits and abuts the spiral springs, so that the spiral springs accurately correspond to the positioning column. The first transmission structure at the output end of the pusher drive can realize the feeding of spiral springs one by one to the positioning column, further improving the accuracy and efficiency of feeding.

[0010] Optionally, the first transmission structure includes a vertical push rod vertically disposed below the positioning block, a vertical slide rail limiting the vertical push rod, a push rod elastic element sleeved on the vertical push rod, and an inclined push rod disposed on the assembly base plate for pushing the vertical push rod.

[0011] By adopting the above technical solution, the first transmission structure, consisting of a vertical push rod, a vertical slide, a push rod elastic element, and an inclined push rod, can realize the sequential feeding of spiral springs to the positioning column, avoiding the problems of incorrect spring posture and difficulty in hook alignment caused by manual operation, and improving the feeding efficiency and accuracy of spiral springs.

[0012] Optionally, a first bearing assembly and a second bearing assembly are sleeved on the positioning post along the axial direction. The first bearing assembly abuts against the assembly base plate, and the outer diameter of the first bearing assembly is smaller than that of the second bearing assembly.

[0013] By adopting the above technical solution, a first bearing group and a second bearing group are sleeved on the positioning post along the axial direction. The first bearing group abuts against the assembly base plate and has an outer diameter smaller than the second bearing group. This makes the installation of the spiral spring on the positioning post more stable, reduces friction, and facilitates the assembly operation of the spiral spring.

[0014] Optionally, the guiding adjustment mechanism includes a guide slide rod, a first guide post disposed on the guide slide rod, a guiding drive member for driving the guide slide rod to slide, and a second guide post disposed on the assembly base plate; The sliding of the guide drive causes the first guide post to have a first state and a second state. When the first guide post is in the first state, a guide gap is formed between the first guide post and the anti-roll post for the spiral spring to anti-roll and transport. When the first guide post is in the second state, the first guide post and the second guide post form a positioning arc-shaped edge for the other end of the spiral spring to be engaged by the hook.

[0015] By adopting the above technical solution, the guide slide, the first guide post, the guide drive component and the second guide post of the guide adjustment mechanism cooperate. When the first guide post is in the first state, it forms a guide gap with the anti-rolling post, which can realize the anti-rolling conveying of the spiral spring. When the first guide post is in the second state, it forms a positioning arc edge with the second guide post, so that the spiral spring body and the hook form a gap for the cover to be inserted and fitted, which facilitates the assembly of the spiral spring and the cover.

[0016] Optionally, the pusher plate has a first groove for the guide slide rod to slide along, the assembly base plate has a second groove communicating with the first groove, the inner diameter of the second groove is larger than that of the first groove, and the guide slide rod is provided with a limiting abutment part for abutting the pusher plate.

[0017] By adopting the above technical solution, the pusher plate is provided with a first slide groove for the guide slide rod to slide and arrange. The assembly substrate is provided with a second slide groove that is connected to the first slide groove and has a larger inner diameter. The guide slide rod is provided with a limiting abutment part, which enables the guide slide rod to slide stably between the pusher plate and the assembly substrate, avoids the guide slide rod from falling off, ensures the normal operation of the guide adjustment mechanism during the pusher process, and improves the assembly efficiency and stability of the coil spring and the cover.

[0018] Optionally, the clamping mechanism includes a rotating pressure rod rotatably mounted on the assembly base plate, a rotating pressure plate disposed on the rotating pressure rod, and a clamping reset component connecting the rotating pressure rod and the assembly base plate.

[0019] By adopting the above technical solution, the spiral spring can be compressed, ensuring its stability during assembly and improving the assembly quality and efficiency of the spring and the cover.

[0020] Optionally, it also includes a limiting mechanism for limiting the reset of the spiral spring after unwinding. The limiting mechanism includes two sets of sliding blocks symmetrically arranged along the unwinding column, a sliding pressure seat for mounting the sliding blocks, and a sliding elastic element connected to the sliding pressure seat. The assembly base plate has a sliding groove for arranging the sliding pressure seat. The two ends of the sliding elastic member are respectively fixed to the bottom of the sliding pressure seat and the bottom wall of the sliding groove. The sliding pressure seat is provided with a locking member that locks to the inner wall of the sliding groove. The outer side of the sliding pressure seat is provided with a pressing part for the edge of the cover to abut. The sliding pressure seat has a slider groove for the sliding block to move. The side wall of the sliding block is provided with a locking block and a block reset member connected to the locking block. The sliding pressure seat is provided with a slider elastic member connected to the sliding block in the slider groove, and a locking slot for the locking block to be inserted is provided at the end of the slider elastic member near the anti-rolling post.

[0021] By adopting the above technical solution, the resetting of the spiral spring after unwinding can be restricted, ensuring the stability and accuracy of the spiral spring during the assembly process, and improving assembly efficiency and quality.

[0022] Optionally, the rotating pressure rod is provided with a driving block for driving the sliding block to slide, the elastic force of the slider elastic element is less than that of the sliding elastic element, and the end of the sliding block near the slider elastic element is provided with a first inclined surface for the driving block to abut against.

[0023] By adopting the above technical solution, the drive block on the rotating pressure rod abuts against the first inclined surface of the sliding block, which can drive the sliding block to slide. The sliding elastic element with a spring force less than that of the block reset component connects the sliding block and the inner wall of the slider groove, which facilitates the control of the sliding block's sliding and reset. This enables the limitation and adjustment of the reset of the spiral spring after rewinding, which is helpful for the assembly of the coil spring and the cover.

[0024] Optionally, the locking slot has an open side facing the fixed base, and the mounting base is provided with a push block corresponding to the locking slot. The sliding block has a sliding inclined surface corresponding to the push block. When the cover presses the sliding pressure seat, the push block abuts against the sliding inclined surface, driving the sliding block to disengage from the locking slot.

[0025] By adopting the above technical solution, when the cover presses the sliding pressure seat, the pushing block can abut against the sliding inclined surface of the sliding block, so that the sliding block can disengage from the locking slot, which facilitates the release of the limit on the spiral spring after the reverse roll, and facilitates the smooth progress of subsequent assembly operations.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The fixed support, assembly base plate, anti-roll mechanism, pushing mechanism, guiding adjustment mechanism and clamping mechanism of this application make the assembly of the spiral spring and the cover more convenient and improve the assembly efficiency. The guide rail has two states. In the first state, the first guide post forms a guide gap with the anti-roll post to guide the anti-roll conveying of the spiral spring. In the second state, the first guide post forms a positioning arc groove with the second guide post, so that the end of the spiral spring forms an insertion groove that fits into the cover, which facilitates the assembly of the spiral spring and the cover. This application, through the setting of a limiting mechanism, can automatically limit and clamp both sides of the spiral spring after the rotating pressure rod is reset, reducing manual tightening operations, improving work efficiency, and automatically pressing the sliding pressure seat into the sliding groove after the cover is installed, avoiding interference.

[0036] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0037] This application discloses an assembly device for a coil spring and a cover.

[0038] Reference Figure 2 An assembly device for a coil spring and a cover includes a fixed support 1, an assembly base plate 2 inclinedly mounted on the fixed support 1, a rewinding mechanism 3 disposed on the assembly base plate 2, a pushing mechanism 4 for pushing out the assembled finished product, a guiding adjustment mechanism 5 slidably mounted on the assembly base plate 2, a pressing mechanism 6, and a feeding mechanism 7.

[0039] The fixed support 1 is a horizontal mounting base frame fixed to the ground. The assembly base plate 2 is a metal rectangular plate, which is fixed to the top of the fixed support 1 at an angle by bolts. The angled placement of the assembly base plate 2 facilitates the manual assembly of the spiral spring and the cover by the workers, reducing the bending labor intensity of the neck.

[0040] Reference Figure 2 and Figure 3The anti-roll mechanism 3 includes a positioning post 31, an anti-roll post 32, and an anti-roll drive component 33. The positioning post 31 is a metal rod vertically fixed to the corner of the assembly base plate 2, used for the initial placement of the spiral spring to be assembled. The anti-roll post 32 is rotatably mounted at the geometric center of the assembly base plate 2, and has a hook groove 321 for inserting a hook into one end of the spiral spring. The anti-roll drive component 33 is an anti-roll motor fixed to a fixed support, its output end connected to the anti-roll post 32 via gear transmission, and the start button for controlling the anti-roll drive component 33 is located at the bottom of the fixed support, allowing the operator to start it by foot. Under the action of the anti-roll mechanism 3, the spiral spring can be anti-rolled and wound onto the anti-roll post 32, reducing the overall outer diameter of the spiral spring and facilitating the operator to insert the cover into the spiral spring. The positioning post 31 also has a first bearing assembly 311 and a second bearing assembly 312 sleeved along its axial direction. The first bearing assembly 311 abuts against the end face of the mounting base plate 2. The outer diameter of the second bearing assembly 312 is larger than that of the first bearing assembly 311. The spiral spring falls onto the first bearing assembly 311 under the action of gravity, which improves the smoothness of the spiral spring rotation when it is reversed. At the same time, the second bearing assembly 312 can reduce the probability of the spiral spring axial movement.

[0041] The pushing mechanism 4 is used to disengage the spiral spring from the anti-coil post 32. It includes a pushing disc 41 and a pushing drive 42. The pushing disc 41 is a circular disc that is rotatably mounted on the mounting base 2. The axis of the pushing disc 41 is coaxial with the anti-coil post 32, and a discharge hole 413 corresponding to the anti-coil post 32 is opened at the center of the pushing disc 41. The pushing drive 42 is a push cylinder fixed to the fixed support, and the output direction of the push cylinder is parallel to the anti-coil post 32. The outer side of the pushing disc 41 and the positioning post 31 are staggered to avoid the movement of the pushing disc 41 affecting the spiral spring on the positioning post 31.

[0042] The feeding mechanism 7 includes a feeding column 71 connected to the positioning column 31 and a first transmission structure 72 disposed between the pushing drive component 42 and the feeding column 71. One end of the feeding column 71 is integrally welded to the positioning column 31, and the entire column is arranged at an angle. Several spiral springs are sleeved on the feeding column 71. These spiral springs can be automatically fed by a robot or manually placed. The spiral springs on the feeding column 71 tend to slide downwards under the action of gravity. The end of the feeding column 71 corresponds to the positioning column 31, and a positioning block 73 is provided on the top surface of the end of the feeding column 71 to limit the spiral springs. The positioning block 73 can prevent the spiral springs from being fed onto the positioning column 31.

[0043] The first transmission structure 72 includes a vertical push rod 721, a vertical slide rail 722, a push rod elastic element 723, and an inclined push rod 724. The first transmission structure 72 can lift a spiral spring that abuts against the positioning block 73 upward. The lifted spiral spring passes over the positioning block 73 under the pressure of the subsequent spiral spring, and thus automatically falls onto the positioning post 31. On the positioning post 31, it automatically slides down onto the assembly base plate 2 by gravity.

[0044] A vertical push rod 721 is slidably mounted on a fixed support, with its top corresponding to a positioning block 73. The top of the vertical push rod 721 has a fitting portion that engages with the bottom of a spiral spring. A vertical slide rail 722 is fixedly mounted on the fixed support 1 to ensure the vertical sliding of the vertical push rod 721. A push rod elastic element 723 is a compression spring that is sleeved on the vertical push rod 721, with both ends of the elastic element 723 fixed to the vertical slide rail 722 and the vertical push rod 721, respectively. The bottom of the vertical push rod 721 has a push rod inclined surface 7211 for pushing the tilting push rod 724.

[0045] Reference Figure 4 and Figure 5 The guiding adjustment mechanism 5 includes a guide slide rod 51, a first guide post 52, a guide drive member 53, and a second guide post 54. The surface of the pusher plate 41 has a first groove 411 for the guide slide rail to slide along, and the mounting base plate 2 has a second groove 412 corresponding to and communicating with the first groove 411. The inner diameter of the second groove 412 is larger than that of the first groove 411. The side wall of the guide slide rod 51 has a limiting abutment part 511 for abutting against the pusher plate 41. The guide drive member 53 is a pushing cylinder fixed to the end of the guide slide rod 51 away from the pusher plate 41.

[0046] A first guide post 52 is fixed on the guide slide rod 51, and a second guide post 54 is fixed on the mounting base plate 2. The first guide post 52 and the second guide post 54 have the same length, and both are less than the thickness of the groove of the cover. The first guide post 52 can have two states by opening and closing the guide drive member 53.

[0047] When the end of the guide slide rod 51 abuts against the end of the first slide groove 411, the limiting abutment part 511 abuts against the outer wall of the pusher plate 41. At this time, the first guide post 52 is in the first state. A guide gap is formed between the first guide post 52 and the anti-rolling post 32 for the spiral spring to be anti-rolled and conveyed. The operator passes one end of the spiral spring through the guide gap and then fixes the hook into the anti-rolling post 32. The anti-rolling drive 33 is activated so that the spiral spring is anti-rolled and wound on the anti-rolling post 32 under the guidance of the guide gap.

[0048] When the guide drive 53 is activated, it drives the guide slide rail to move away from the pusher plate 41, causing the first guide post 52 to move to the other side of the second guide post 54. At this time, the first guide post 52 and the second guide post 54 form a positioning arc edge. The positioning arc edge is centered on the anti-rolled post 32. The radius of the positioning arc edge is larger than the outer diameter of the anti-rolled spiral spring, so that a snap-in gap is formed between the hook and the spiral spring body. The snap-in gap allows the operator to easily insert and match the slot and hook on the cover.

[0049] The clamping mechanism 6 includes a rotating pressure rod 61, a rotating pressure plate 62, and a clamping reset component 63. The rotating pressure rod 61 is rotatably mounted on the top of the mounting base plate 2, and the rotating pressure plate 62 is fixed to the end of the rotating pressure rod 61. The clamping reset component 63 is a tension spring, with its two ends fixed to the mounting base plate 2 and the end of the rotating pressure rod 61, respectively. The operator manually presses the rotating pressure rod 61, causing the rotating pressure plate 62 to press against the anti-coil column 32. The width of the rotating pressure plate 62 is greater than the outer diameter of the spiral spring after anti-coil, thereby limiting the probability of the spiral spring shifting during anti-coil by the rotating pressure plate 62.

[0050] The implementation principle of the assembly equipment for coil springs and covers in this application embodiment is as follows: the coil springs are fed one by one to the positioning column 31 through the feeding mechanism 7. The operator takes one end of the hook and inserts it into the anti-coiling column 32, rotates the rotating pressure rod 61, and starts the anti-coiling drive 33. The coil spring is anti-coiled and wound on the anti-coiling column 32. The operator resets and rotates the pressure rod 61, presses the coil spring with one hand, and takes the cover with the other hand and covers the coil spring. The hook at the other end is inserted and engaged with the cover. The anti-coiling drive 33 is driven in the opposite direction, so that the coil spring is automatically installed into the cover under the action of elasticity. Example

[0051] Reference Figure 6 and Figure 7 After completing the anti-coiling operation, the operator needs to release the rotating pressure rod 61 and then press it by hand against the side wall and top of the spiral spring to restrict its elastic return. To further restrict the return of the spiral spring, this application also includes a limiting mechanism 8.

[0052] The limiting mechanism 8 includes two sets of sliding blocks 81 symmetrically arranged along the anti-rolling column 32, a sliding pressure seat 82 for mounting the sliding blocks 81, and a sliding elastic element 83. The pusher plate 41 has a relief groove 412 corresponding to the sliding pressure seat 82. The inner hole of the sliding elastic element 83 is also provided with a telescopic rod structure (not shown in the figure) to improve the stability of the sliding pressure seat 82 in the sliding groove 21.

[0053] The assembly base plate 2 has a sliding groove 21 for arranging the sliding pressure seat 82. The extending direction of the sliding groove 21 is parallel to the moving direction of the pusher plate 41. The sliding elastic element 83 is a compression spring, and its two ends are respectively fixed to the bottom wall of the sliding groove 21 and the bottom of the sliding pressure seat 82.

[0054] The side wall of the sliding pressure seat 82 is provided with a locking element 822 that locks into the sliding groove 21. The locking element 822 is a ball-head plunger of the prior art. The inner wall of the sliding groove 21 has a locking ball groove 211 that mates with the locking element 822. When the locking frame engages with the locking ball groove 211, the sliding elastic element 83 is in a normal uncompressed state.

[0055] The sliding base 82 has a slider groove 821 for sliding the sliding blocks 81. The slider groove 821 is arranged at an angle relative to the top of the sliding blocks 81. The two sliding blocks 81 can move toward or away from the anti-coil post 32 to limit and fix the outer wall of the anti-coiled spiral spring, reducing the probability of the anti-coiled spiral spring returning to its original position. At the same time, the sliding blocks 81 can form an anti-coil gap with the first guide post 52 for the spiral spring to anti-coil.

[0056] The sliding block 81 has a mounting groove 811 on its side wall, and a locking block 812 and a block reset member 813 are provided in the mounting groove 811. The block reset member 813 is a compression spring, and its two ends are fixed to the locking block 812 and the inner bottom wall of the mounting groove 811, respectively.

[0057] The sliding base 82 has a slider elastic element 823, which is a tension spring, connected to the slider block 81 in the slider groove 821. The sliding base 82 also has a locking groove 824 at the end of the slider groove 821 away from the slider elastic element 823 for the slider block 81 to be inserted. When the tension spring is in its normal position, the locking block 812 is fully positioned within the mounting groove 811.

[0058] The top of the sliding block 81 is provided with a first inclined surface 814, and the rotating pressure rod 61 is provided with a driving block 611 corresponding to the first inclined surface 814. When the rotating pressure rod 61 rotates, it can drive the sliding block 81 groove anti-rolling post 32 to move, thereby moving the locking block 812 to correspond with the locking groove 824. The elastic force of the slider elastic element 823 is less than that of the sliding elastic element 83, so that the force of the driving block 611 on the sliding block 81 will not disengage the locking element 822 from the locking ball groove 211.

[0059] Combination Figure 8The sliding pressure base 82 has a pressing part 825 at the end away from the anti-rolling post 32, which abuts against the edge of the cover. The locking slot 824 is open towards the bottom of the fixed base, and a push block 22 corresponding to the locking slot 824 is provided on the mounting base 2. The bottom of the locking block 812 has a sliding inclined surface 8121 corresponding to the push block 22. The sliding inclined surface 8121 is provided so that when the cover drives the sliding pressure base 82 to move down through the pressing part 825, the sliding inclined surface 8121 and the push block 22 abut against each other, the sliding block 81 disengages from the locking slot 824, and under the action of the slider elastic member 823, the sliding block 81 moves along the extension direction of the slider groove 821, so that the top of the sliding block 81 is located below the top surface of the pusher plate 41, thereby ensuring that the sliding block 81 will not affect the reset of the spiral spring.

[0060] The implementation principle of the assembly device for a coil spring and a cover in this application embodiment is as follows: when the rotating pressure rod 61 rotates, the two sets of sliding blocks 81 move toward the anti-coil post 32, so that the locking block 812 is inserted into the locking groove; after the coil spring completes anti-coil, the rotating pressure rod 61 automatically resets, and the side wall of the anti-coiled coil spring is limited by the sliding block 81, so that the operator does not need to use one hand to limit the coil spring after anti-coil; Then, align and insert the cover and the spiral spring. During the closing process of the cover, the sliding pressure seat 82 is pressed down into the sliding groove 21, and at the same time, the locking block 22 is pushed to abut against the sliding inclined surface 8121, so that the sliding locking block 81 disengages from the locking groove 824, ensuring the automatic reset of the spiral spring.

[0061] 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.
