Description

Technical Field

[0001] This invention relates to the field of spring processing technology, and in particular to an automatic feeding type spring end leveling device. Background Technology

[0002] Spring end leveling is an important process step in spring manufacturing. When springs are used in support structures, both ends of the spring need to be leveled to improve the spring's load-bearing capacity and stability, and to ensure the perpendicularity of the spring axis.

[0003] Patent document CN205732711U discloses a pigtail-shaped end leveling device for a spring body, comprising: a worktable; a hydraulic cylinder including a fixed part fixed on the worktable and a telescopic part that extends and retracts relative to the fixed part; a leveling fixture mounted on the telescopic part of the hydraulic cylinder to be driven to perform telescopic actions; and a positioning support mechanism including two parallel rails fixed on the worktable, the two parallel rails forming a workpiece placement position corresponding to the leveling fixture, each rail being equipped with a movable positioning block that can move along the rail and be fixed on the rail, and the movable positioning block being equipped with a positioning support rod extending toward the workpiece placement position.

[0004] In existing technologies, leveling fixtures are typically used to compress the ends of springs. In actual operation, because springs have elastic extension and contraction capabilities, when the end pressure is small, the spring used to bear and transmit loads can elastically contract and rebound after the pressure is released, resulting in poor end leveling effect. When the end pressure is greater than the spring's load-bearing capacity, the two ends of the spring can be effectively leveled under pressure without being compressed, but the spring as a whole is prone to breakage and permanent deformation under greater pressure, thus affecting the subsequent use effect of the spring. Summary of the Invention

A heating ring is fixedly installed in the annular groove. An exhaust pipe is fixedly connected to the bottom of the sealing ring. A pressure relief valve is fixedly installed on the exhaust pipe.

[0019] Preferably, limit strips are fixedly connected to both sides of the adjacent ends of the two sealing rings, and plug-in housings are fixedly connected to both ends of the two arc-shaped clamps.

[0020] Preferably, the feeding component includes:

[0021] The feeding plate is set between two support bars. The top of the feeding plate has multiple second arc-shaped grooves, which are respectively connected to the first arc-shaped grooves at both ends.

[0025] Preferably, the lifting assembly includes:

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. This invention uses two sleeve rods inserted from both ends of the spring body and a spiral groove to limit the middle part of the spring body. This allows the middle part of the spring body to be limited and supported during compression and leveling, thereby preventing deformation of the middle part of the spring body under the pressure of both ends. This forms an elastic ring in the middle part and a support ring at both ends of the spring body, ensuring effective leveling of the spring body while reducing the impact of end leveling on the actual use of the spring body.

[0032] 2. Through the meshing action of the gear and the external gear ring, the two compression rings rotate one revolution in opposite directions, ensuring that the limiting blocks contact the corresponding spiral ends of the spring body. The two limiting blocks abut against the two spiral ends of the spring body respectively, thereby limiting the rotation of the spring body and adjusting the spring body to the correct angle, ensuring that the spring body accurately corresponds to the spiral groove on the arc-shaped fixture.

[0033] 3. The extrusion and leveling area is heated by the heating ring inside the annular groove, thereby reducing the rebound effect after the spring body end is extruded and leveled, ensuring the leveling effect of the spring body end. When the heating ring is heated, the high pressure generated inside the sealing ring is released through the pressure relief valve on the exhaust pipe, improving the safety level during heating.

[0051] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0052] like Figures 1 to 16 The automatic feeding type spring end leveling device shown includes a base plate 1, and further includes:

[0053] U-shaped bracket 2, U-shaped bracket 2 is set above base plate 1, and sleeve rods 3 are set on both sides inside U-shaped bracket 2 (e.g. Figure 7 As shown), the ends of the two sleeve rods 3 that are far apart from each other are rotatably connected to the compression rings 4. The U-shaped bracket 2 is equipped with a displacement component, which is used to drive the two sleeve rods 3 to move closer to each other.

[0054] Two support bars 5 are fixedly connected to the base plate 1 and located between two sleeve rods 3. Multiple first arc-shaped grooves 6 are opened on the top of each support bar 5. The sleeve rods 3 are coaxially arranged with the corresponding first arc-shaped grooves 6. A feeding assembly is provided between the two support bars 5.

[0055] Two curved clamps 7 are positioned above the two sleeve rods 3, as shown. Figure 13 As shown, a spiral groove 8 is provided on the arc surface of the arc fixture 7, and movable components are provided on the two arc fixtures 7. The movable components are used to drive the two arc fixtures 7 to move and contact each other.

[0056] The lifting assembly is mounted on the U-shaped bracket 2 and is used to drive the U-shaped bracket 2 to move vertically.

[0057] The adjustment component is set on the extrusion ring 4 and is used to adjust the angle before the spring is leveled.

[0058] The spring body 49 is placed on top of the two support bars 5, and the spring body 49 is limited by the corresponding first arc groove 6. When the spring body 49 is located inside the first arc groove 6 coaxial with the sleeve rod 3, the displacement component drives the two sleeve rods 3 to move closer to each other, so that the two sleeve rods 3 move from both ends of the spring body 49 into the spring body 49 until the distance between the adjacent sides of the two compression rings 4 is the same as the length of the spring body 49, so that the compression ring 4 contacts the corresponding end of the spring body 49 (e.g., Figure 11 As shown), the lever 3 stops moving, and there is still a certain distance between the two levers 3;

[0059] Then, the lifting component drives the U-shaped bracket 2 to rise vertically, and drives the two sleeve rods 3 and the sleeved spring body 49 to rise synchronously between the two arc-shaped clamps 7. Then, the adjustment component adjusts the angle of the spring body 49 so that the position of the spiral ring of the spring body 49 corresponds with the position of the spiral groove 8 on the arc-shaped clamp 7. Then, the movable component drives the two arc-shaped clamps 7 to approach and contact each other, thereby wrapping the middle part of the spring body 49 in the arc-shaped surface of the two arc-shaped clamps 7, and limiting the middle part of the spring body 49 through the spiral groove 8.

[0060] Next, the displacement component drives the two sleeve rods 3 to continue to move closer to each other, so that the two extrusion rings 4 extrude and level the two ends of the spring body 49 respectively. During the extrusion and leveling process, the middle part of the spring body 49 is limited by the spiral groove 8, so that it will not shrink inward with the extrusion of the two ends. After the extrusion is completed, the middle part of the spring body 49 is still at the initial pitch, while the pitch of the two ends decreases under the extrusion, thus forming a leveling support ring. Finally, the movable component drives the two arc-shaped clamps 7 to move away from each other and return to the initial position. Then, the lifting component drives the U-shaped bracket 2 to descend vertically, so that the leveled spring body 49 falls back into the corresponding two first arc-shaped grooves 6. Then, the displacement component drives the two sleeve rods 3 to move away from each other and return to the initial position, so that the sleeve rods 3 are disengaged from the leveled spring body 49. The feeding component transports the spring body 49 in the adjacent first arc-shaped grooves 6 forward and transports the leveled spring body 49 from the top of the support bar 5, thus automatically feeding the spring body 49 and automatically unloading it after processing.

[0061] This invention uses two sleeve rods 3 inserted from both ends of the spring body 49 and a spiral groove 8 to limit the middle part of the spring body 49. This allows the middle part of the spring body 49 to be limited and supported during compression and leveling, thereby preventing deformation of the middle part of the spring body 49 under the pressure of both ends. This forms an elastic ring in the middle part and a support ring at both ends of the spring body 49, ensuring effective leveling of the spring body 49 while reducing the impact of end leveling on the actual use of the spring body 49.

[0062] As a further embodiment of the present invention, the displacement component includes:

[0063] Two mounting housings 9 are fixedly connected to both sides of the U-shaped bracket 2. A slider 10 is slidably connected inside each mounting housing 9. One end of each slider 10 extends into the interior of the U-shaped bracket 2 and is fixedly connected to a mounting plate 11. Two sleeve rods 3 are fixedly connected to the two mounting plates 11 respectively.

[0064] Two first electric cylinders 12 are fixedly mounted on two mounting housings 9 respectively, and the drive shafts of the first electric cylinders 12 are fixedly connected to the corresponding sliders 10 respectively.

[0065] The transmission shafts of the two first electric cylinders 12 move synchronously, thereby driving the corresponding slider 10 to slide along the inside of the mounting housing 9, so that the mounting plate 11 drives the adjacent sleeve rod 3 to move synchronously, thereby driving the sleeve rod 3 to move.

[0066] The drive shaft of the first electric cylinder 12 is set to have two displacement strokes. When the compression ring 4 on the sleeve 3 contacts the corresponding end of the spring body 49, and the distance between the adjacent ends of the two compression rings 4 is the same as the initial length of the spring body 49, the first electric cylinder 12 stops working and completes the first displacement stroke. When the two arc-shaped clamps 7 contact each other and limit the middle part of the spring body 49 through the spiral groove 8, the drive shaft of the first electric cylinder 12 continues to move and drives the adjacent ends of the two sleeves 3 to contact. The first electric cylinder 12 stops working and completes the second displacement stroke.

[0067] As a further embodiment of the present invention, the adjustment component includes:

[0068] Two limit blocks 13 (e.g.) Figure 11 As shown), two limiting blocks 13 are fixedly connected to one adjacent end of two extrusion rings 4, and external toothed rings 14 are fixedly connected to the surface of both extrusion rings 4.

[0069] Two first motors 15 are fixedly mounted on two mounting plates 11 respectively. Gears 16 are fixedly connected to the output shaft of each first motor 15. The two gears 16 mesh with the corresponding external gear rings 14 respectively.

[0070] When the distance between the adjacent ends of the two compression rings 4 is the same as the initial length of the spring body 49, the two first motors 15 work synchronously, thereby causing the output shaft of the first motor 15 to drive the gear 16 to rotate. Through the meshing action of the gear 16 and the external gear ring 14, the two compression rings 4 rotate one revolution in opposite directions, ensuring that the limiting block 13 contacts the corresponding spiral end of the spring body 49. The two limiting blocks 13 respectively abut against the two spiral ends of the spring body 49, thereby limiting the rotation of the spring body 49 and adjusting the spring body 49 to the correct angle, ensuring that the spring body 49 accurately corresponds to the spiral groove 8 on the arc surface fixture 7.

[0071] As a further embodiment of the present invention, sealing rings 17 are slidably fitted onto the surfaces of both extrusion rings 4. Multiple connecting blocks 18 are fixedly connected circumferentially to the sealing rings 17. Limiting pins 19 are slidably inserted into each connecting block 18. One end of each limiting pin 19 is fixedly connected to a corresponding mounting plate 11. A limiting spring 20 is fitted onto each limiting pin 19, and the limiting spring 20 is fixedly connected between the corresponding mounting plate 11 and the connecting block 18. Figure 12 As shown, an annular groove 21 is provided inside the sealing ring 17, and a heating ring 22 is fixedly installed in the annular groove 21. An exhaust pipe 23 is fixedly connected to the bottom of the sealing ring 17, and a pressure relief valve 24 is fixedly installed on the exhaust pipe 23.

[0072] The two sleeve rods 3 move from both ends of the spring body 49 into the interior of the spring body 49, and when the compression ring 4 contacts the spring body 49, the sealing ring 17 moves with the compression ring 4, and the corresponding end of the spring body 49 is fitted inside the sealing ring 17. When the two arc-shaped clamps 7 approach and contact each other, one end of the sealing ring 17 contacts one end of the two arc-shaped clamps 7 (e.g., Figure 9 As shown), when the two compression rings 4 move and compress the two ends of the spring body 49 respectively, the sealing ring 17 moves relative to the corresponding compression ring 4, and the connecting block 18 moves along the sliding insertion of the limiting pin 19, thereby compressing the limiting spring 20 to produce compression deformation, so that the two ends of the spring body 49 are always inside the corresponding sealing ring 17 during the compression and leveling process, and the compression and leveling area is heated by the heating ring 22 inside the annular groove 21, thereby reducing the rebound effect after the end of the spring body 49 is compressed and leveled, ensuring the leveling effect of the end of the spring body 49. When the heating ring 22 is heated, the high pressure generated inside the sealing ring 17 is released by the pressure relief valve 24 on the exhaust pipe 23, improving the safety level during heating.

[0073] After leveling, the two curved clamps 7 move away from each other and return to their initial positions through the action of the movable components. The sealing ring 17 loses the contact obstruction of the curved clamps 7, and the elastic extension of the limiting spring 20 causes the limiting spring 20 to press the connecting block 18, thereby causing the sealing ring 17 and the corresponding pressing ring 4 to return to their initial relative positions.

[0074] As a further embodiment of the present invention, limit strips 25 are fixedly connected to both sides of the adjacent end of the two sealing rings 17, and plug-in housings 26 are fixedly connected to both ends of the two arc-shaped clamps 7.

[0075] When the two curved clamps 7 approach and contact each other through the action of the movable components, the curved clamps 7 drive the plug-in housing 26 to move synchronously and approach the corresponding limiting strip 25, so that the limiting strip 25 is located inside the corresponding plug-in housing 26 for limiting. Thus, when the heating ring 22 heats the inside of the sealing ring 17, the limiting strip 25 is located inside the plug-in housing 26 and always limits one end of the sealing ring 17 to one end of the two curved clamps 7, ensuring the stability of the contact position between the sealing ring 17 and the curved clamps 7, preventing the gas inside the sealing ring 17 from expanding due to heat and impacting the contact position between the sealing ring 17 and the curved clamps 7, thereby causing the sealing ring 17 to disengage from the curved clamps 7, thus reducing the accidental leakage of heating gas and ensuring the heating effect of the leveling end of the spring body 49.

[0076] As a further embodiment of the present invention, the feeding component includes:

[0077] Feeding plate 27 (e.g.) Figure 14As shown), the feeding plate 27 is disposed between two support bars 5. The top of the feeding plate 27 is provided with multiple second arc-shaped grooves 28, which are respectively connected to the first arc-shaped grooves 6 at both ends.

[0078] A fixed plate 29 is fixedly connected to the base plate 1. A limiting base 30 is fixedly connected to one side of the fixed plate 29. A loop groove 31 is provided on the limiting base 30. A first sliding frame 32 is horizontally slidably connected to the fixed plate 29. A second sliding frame 33 is vertically slidably connected to the first sliding frame 32. A fixed rod 34 is fixedly connected to one side of the second sliding frame 33. One end of the fixed rod 34 is fixedly connected to the bottom of the feeding plate 27. A fixed pin 35 is fixedly inserted into the fixed rod 34. A limiting roller 36 is fixedly connected to one end of the fixed pin 35. One end of the limiting roller 36 is located inside the loop groove 31. A rotating shaft 37 is rotatably connected to the limiting base 30. One end of the rotating shaft 37 is located at the center of the loop groove 31 and is fixedly connected to a guide strip 38. A strip groove 39 is provided on the guide strip 38. The other end of the limiting roller 36 is located inside the strip groove 39. A second motor 40 is fixedly installed on the fixed plate 29. The output shaft of the second motor 40 is fixedly connected to the rotating shaft 37.

[0079] The output shaft of the second motor 40 rotates, driving the rotating shaft 37 to rotate. The rotating shaft 37 drives the guide bar 38 to rotate, and guides the limiting roller 36 through the strip groove 39 on the guide bar 38, causing the limiting roller 36 to move unidirectionally along the internal trajectory of the loop groove 31. The fixed rod 34 moves through the connection of the fixed pin 35. During the movement, the fixed rod 34 moves in coordination with the horizontal sliding of the first sliding frame 32 and the vertical sliding of the second sliding frame 33, and drives the feeding plate 27 to reciprocate along the fixed trajectory. The second arc groove 28 limits the spring body 49, and the multiple spring bodies 49 are transported as a whole, thereby realizing the automatic feeding of the spring bodies 49.

[0080] As a further embodiment of the present invention, each end of the support bar 5 near the feeding direction is fixedly connected to an inclined unloading bar 41, and a collection frame 42 is provided on the bottom plate 1, the collection frame 42 being located below the two inclined unloading bars 41.

[0081] The feeding plate 27 uses the second arc groove 28 to limit the spring body 49 and transport the spring body 49 as a whole. It also transports the leveled spring body 49 simultaneously, so that the leveled spring body 49 moves to the top of the two inclined unloading bars 41. During the reciprocating movement of the feeding plate 27, the support and limit on the leveled spring body 49 are released, so that the leveled spring body 49 slides down along the inclined unloading bars 41 and falls into the collection frame 42, thereby realizing the automatic unloading and collection of the leveled spring body 49.

[0082] As a further embodiment of the present invention, such as Figure 15 As shown, multiple arc-shaped baffles 43 are fixedly connected inside the second arc-shaped groove 28, and the arc-shaped baffles 43 are all inclined to one side;

[0083] When the spring body 49 is limited by the second arc-shaped groove 28 and the first arc-shaped grooves 6 on both sides, the arc-shaped stop 43 inside the second arc-shaped groove 28 is located between two adjacent spiral rings of the spring body 49. Thus, when the loading plate 27 transports the spring body 49 as a whole, the arc-shaped stop 43 can limit the spring body 49, thereby preventing the spring body 49 from sliding inside the second arc-shaped groove 28 and ensuring the stability of the spring body 49 during transportation. Furthermore, the arc-shaped stop 43 is inclined in the same direction as the spiral rings. When the spring body 49 is placed in the second arc-shaped groove 28 in the opposite direction, the arc-shaped stop 43 cannot enter between two adjacent spiral rings of the spring body 49. This allows for the differentiation of the spiral direction when the spring body 49 is placed, ensuring the accuracy of the spiral direction when the spring body 49 is placed.

[0084] As a further embodiment of the present invention, the lifting assembly includes:

[0085] The lifting bracket 44 is fixedly connected to the base plate 1, and the U-shaped bracket 2 is located inside the lifting bracket 44.

[0086] The second electric cylinder 45 is fixedly installed on the lifting bracket 44. The drive shaft of the second electric cylinder 45 is fixedly connected to the U-shaped bracket 2. Multiple first connecting pins 46 are fixedly connected to the U-shaped bracket 2. The first connecting pins 46 are all slidably inserted into the lifting bracket 44.

[0087] The U-shaped bracket 2 is moved by the drive shaft of the second electric cylinder 45, and the first connecting pin 46 is moved and limited along the sliding connection of the lifting bracket 44, so that the U-shaped bracket 2 can move vertically inside the lifting bracket 44.

[0088] As a further embodiment of the present invention, the active component includes:

[0089] Two third electric cylinders 47 are fixedly installed on the lifting bracket 44. The drive shafts of the two third electric cylinders 47 are respectively fixedly connected to two arc-shaped clamps 7. Multiple second connecting pins 48 are fixedly connected to the arc-shaped clamps 7. The second connecting pins 48 are slidably inserted into the lifting bracket 44.

[0090] The transmission shaft of the third electric cylinder 47 drives the arc-shaped clamp 7 to move, and causes the second connecting pin 48 to move and limit along the sliding connection of the lifting bracket 44, thereby causing the arc-shaped clamp 7 to move horizontally, so that the two arc-shaped clamps 7 move closer to each other and further apart.

[0091] Working principle of this invention:

[0092] The spring body 49 is placed on top of the two support bars 5, and the spring body 49 is limited by the corresponding first arc groove 6. When the spring body 49 is located inside the first arc groove 6 coaxial with the sleeve rod 3, the two sleeve rods 3 are driven to move closer to each other by the action of the displacement component, so that the two sleeve rods 3 move from both ends of the spring body 49 into the spring body 49 until the distance between the adjacent sides of the two extrusion rings 4 is the same as the length of the spring body 49, so that when the extrusion ring 4 contacts the corresponding end of the spring body 49, the sleeve rod 3 stops moving. At this time, there is still a certain distance between the two sleeve rods 3.

[0093] Then, the lifting component drives the U-shaped bracket 2 to rise vertically, and drives the two sleeve rods 3 and the sleeved spring body 49 to rise synchronously between the two arc-shaped clamps 7. Then, the adjustment component adjusts the angle of the spring body 49 so that the position of the spiral ring of the spring body 49 corresponds with the position of the spiral groove 8 on the arc-shaped clamp 7. Then, the movable component drives the two arc-shaped clamps 7 to approach and contact each other, thereby wrapping the middle part of the spring body 49 in the arc-shaped surface of the two arc-shaped clamps 7, and limiting the middle part of the spring body 49 through the spiral groove 8.

[0094] Next, the displacement component drives the two sleeve rods 3 to continue moving closer to each other, so that the two extrusion rings 4 extrude and level the two ends of the spring body 49 respectively. During the extrusion and leveling process, the middle part of the spring body 49 is limited by the spiral groove 8, so that it will not shrink inward with the extrusion action of the two ends. After the extrusion is completed, the middle part of the spring body 49 is still at the initial pitch, while the pitch of the two ends decreases under the extrusion action, thus forming a leveling support ring. Finally, the movable component drives the two arc-shaped clamps 7 to move away from each other and return to the initial position. Then, the lifting component drives the U-shaped bracket 2 to descend vertically, so that the leveled spring body 49 falls back into the corresponding two first arc-shaped grooves 6. Then, the displacement component drives the two sleeve rods 3 to move away from each other and return to the initial position, so that the sleeve rods 3 disengage from the inside of the leveled spring body 49. The feeding component transports the spring body 49 inside the adjacent first arc-shaped grooves 6 forward and transports the leveled spring body 49 away from the top of the support bar 5, thus automatically feeding the spring body 49 and automatically unloading it after processing.
