Description

Technical Field

[0001] The present invention relates to the technical field of spring processing, in particular to an automatic loading type spring end leveling processing device. Background Art

[0002] Spring end leveling is an important process step in spring processing. When the spring is used in a supporting structure, both ends of the spring need to be leveled to improve the spring's load-bearing capacity and stability and ensure the verticality of the spring axis.

[0003] The patent document with publication number CN205732711U discloses a leveling device for the pigtail-shaped end of a spring body, comprising: a workbench; a hydraulic cylinder, which comprises a fixed part fixed on the workbench and a telescopic part that is telescopic relative to the fixed part; a leveling tool, which is assembled on the telescopic part of the hydraulic cylinder to be driven to perform a telescopic action; a positioning support mechanism, which comprises two parallel rails fixed on the work platform, a workpiece placement position corresponding to the leveling tool is formed between the two parallel rails, each of the rails is equipped with a movable positioning block that can move along the rail and can be fixed on the rail, and the movable positioning block is equipped with a positioning support rod extending toward the workpiece placement position.

[0004] In the prior art, a leveling tool is usually used to squeeze the ends of the spring. In actual operation, since the spring has the ability to elastically stretch and contract, when the end pressure is small, the spring used to bear and transfer the load can elastically contract and rebound after the pressure is released, resulting in poor leveling effect of the end. When the end pressure is greater than the bearing capacity of the spring, the two ends of the spring can be effectively leveled by being compressed in a state where they cannot be compressed, but the spring as a whole is prone to breakage and permanent deformation under the action of large pressure, thereby affecting the subsequent use effect of the spring.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0022] like Figures 1 to 16 The automatic loading spring end leveling processing device shown includes a base plate 1 and further includes: U-shaped bracket 2, U-shaped bracket 2 is set above the bottom plate 1, and sleeve rods 3 are set on both sides of the inside of the U-shaped bracket 2 (such as Figure 7 As shown), the ends of the two sleeve rods 3 that are away from each other are rotatably connected to the extrusion ring 4, and a displacement component is provided on the U-shaped bracket 2, which is used to drive the two sleeve rods 3 closer to each other; Two support bars 5, both of which are fixedly connected to the bottom plate 1 and located between the two sleeve rods 3. The tops of the support bars 5 are each provided with a plurality of first arcuate grooves 6. The sleeve rods 3 are coaxially arranged with the corresponding first arcuate grooves 6. A loading assembly is provided between the two support bars 5; Two arc surface clamps 7 are arranged above the two sleeve rods 3, as shown in FIG. Figure 13 As shown, a spiral groove 8 is provided on the arc surface of the arc surface clamp 7, and a movable component is provided on the two arc surface clamps 7, and the movable component is used to drive the two arc surface clamps 7 to move and contact; A lifting assembly is provided on the U-shaped bracket 2 and is used to drive the U-shaped bracket 2 to lift vertically; Adjustment assembly, the adjustment assembly is arranged on the extrusion ring 4, and the adjustment assembly is used to adjust the angle of the spring before leveling; The spring body 49 is placed on the 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 approach each other by the action of the displacement component, so that the two sleeve rods 3 are respectively moved from the two ends of the spring body 49 to the inside of 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 the extrusion ring 4 is in contact with the corresponding end of the spring body 49 (as shown in FIG. Figure 11 As shown), the sleeve rods 3 stop moving, and at this time there is still a certain distance between the two sleeve rods 3; Then, the U-shaped bracket 2 is driven to rise vertically by the action of the lifting component, and the two sleeve rods 3 and the sleeved spring body 49 are driven to rise synchronously between the two arc-surface clamps 7. Then, the angle of the spring body 49 is adjusted by the adjustment component so that the spiral coil of the spring body 49 corresponds to the position of the spiral groove 8 on the arc-surface clamp 7. Then, the two arc-surface clamps 7 are driven to approach each other and contact each other by the action of the movable component, so that the middle part of the spring body 49 is wrapped in the arc-shaped surfaces of the two arc-surface clamps 7, and the middle part of the spring body 49 is limited by the spiral groove 8. Then, the two sleeve rods 3 are driven to continue to approach each other through the action of the displacement component, so that the two extrusion rings 4 respectively squeeze and level the two ends of the spring body 49. 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 is reduced under the extrusion action, thereby forming a leveling support ring. Finally, the two arc surface clamps 7 are driven to move away from each other and return to the initial position through the action of the movable component, and then the U-shaped bracket 2 is driven to drop vertically through the action of the lifting component, so that the leveled spring body 49 falls back into the corresponding two first arc grooves 6. The two sleeve rods 3 are driven to move away from each other and return to the initial position through the action of the displacement component, so that the sleeve rod 3 is separated from the leveled spring body 49. The spring body 49 in the adjacent first arc grooves 6 is transported forward through the action of the loading component, and the leveled spring body 49 is transported and separated from the top of the support bar 5, thereby automatically loading the spring body 49 and automatically unloading after processing. The present invention uses two sleeve rods 3 inserted from both ends of the spring body 49 and the spiral groove 8 to limit the middle part of the spring body 49, so that the two ends of the spring body 49 can limit and support the middle part of the spring body 49 when it is extruded and leveled, thereby preventing the middle part of the spring body 49 from being deformed under the pressure of the two ends, so that the spring body 49 forms an elastic ring in the middle part and support rings at both ends. While ensuring the effective leveling of the spring body 49, the influence of the end leveling on the actual use of the spring body 49 is reduced.

[0023] As a further embodiment of the present invention, the displacement assembly comprises: Two mounting shells 9, the two mounting shells 9 are fixedly connected to both sides of the U-shaped bracket 2, and the interior of the mounting shells 9 is slidably connected to a slider 10, one end of the slider 10 extends to the interior of the U-shaped bracket 2 and is fixedly connected to a mounting plate 11, and the two sleeve rods 3 are fixedly connected to the two mounting plates 11; Two first electric cylinders 12, the two first electric cylinders 12 are fixedly mounted on the two mounting housings 9, respectively, and the transmission shafts of the first electric cylinders 12 are fixedly connected to the corresponding sliders 10; The transmission shafts of the two first electric cylinders 12 move synchronously, thereby driving the corresponding sliders 10 to slide along the inside of the mounting housing 9, so that the mounting plate 11 drives the adjacent sleeve rods 3 to move synchronously, thereby driving the sleeve rods 3 to move; The transmission shaft of the first electric cylinder 12 is set to two displacement strokes. When the extrusion ring 4 on the sleeve rod 3 contacts the corresponding end of the spring main body 49, so that the distance between the adjacent ends of the two extrusion rings 4 is the same as the initial length of the spring main body 49, the first electric cylinder 12 stops working and completes the first displacement stroke. When the two arc-surface clamps 7 contact each other and limit the middle part of the spring main body 49 through the spiral groove 8, the transmission shaft of the first electric cylinder 12 continues to move and drives the adjacent ends of the two sleeve rods 3 to contact, and the first electric cylinder 12 stops working and completes the second displacement stroke.

[0024] As a further embodiment of the present invention, the adjustment component includes: Two limit blocks 13 (such as Figure 11 As shown), the two limiting blocks 13 are respectively fixedly connected to the adjacent ends of the two extrusion rings 4, and the surfaces of the two extrusion rings 4 are fixedly connected to the outer gear ring 14; Two first motors 15, the two first motors 15 are fixedly mounted on the two mounting plates 11, and the output shafts of the first motors 15 are fixedly connected to gears 16, and the two gears 16 are respectively engaged with corresponding outer gear rings 14; When the distance between the adjacent ends of the two extrusion rings 4 is the same as the initial length of the spring body 49, the two first motors 15 work synchronously, so that the output shaft of the first motor 15 drives the gear 16 to rotate, and through the meshing action of the gear 16 and the outer gear ring 14, the two extrusion rings 4 rotate one circle in opposite directions, ensuring that the limit block 13 contacts the spiral end corresponding to the spring body 49, and the two limit blocks 13 respectively support 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 clamp 7.

[0025] As a further embodiment of the present invention, the surfaces of the two extrusion rings 4 are slidably sleeved with sealing rings 17, and a plurality of connecting blocks 18 are fixedly connected to the sealing rings 17 along the circumferential direction. The connecting blocks 18 are slidably inserted with limit pins 19, and one end of the limit pins 19 is fixedly connected to the corresponding mounting plate 11. A limit spring 20 is sleeved on the limit pin 19, and the limit 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 formed inside the sealing ring 17, 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; The two sleeve rods 3 move from both ends of the spring body 49 to the inside of the spring body 49, and when the extrusion ring 4 contacts the spring body 49, the sealing ring 17 moves with the extrusion ring 4, and the corresponding end of the spring body 49 is sleeved inside the sealing ring 17. When the two arc-surface clamps 7 approach and contact each other, one end of the sealing ring 17 contacts one end of the two arc-surface clamps 7 (as shown in FIG. Figure 9 As shown), and when the two extrusion rings 4 move and extrude the two ends of the spring body 49 respectively, the sealing ring 17 and the corresponding extrusion ring 4 move relative to each other, and the connecting block 18 moves along the sliding insertion of the limit pin 19, thereby squeezing the limit spring 20 to produce compression deformation, so that the two ends of the spring body 49 are always located inside the corresponding sealing ring 17 during the extrusion leveling process, and the extrusion leveling position is heated by the heating ring 22 inside the annular groove 21, thereby reducing the rebound effect of the end of the spring body 49 after extrusion leveling, ensuring the leveling effect of the end of the spring body 49, and when the heating ring 22 is heated, the high pressure generated by the heating inside the sealing ring 17 is released through the pressure relief valve 24 on the exhaust pipe 23, thereby improving the safety level during heating; After leveling is completed, the two arc-surface clamps 7 move away from each other and return to their initial positions through the action of the movable component. The sealing ring 17 loses the contact obstruction of the arc-surface clamp 7, and the elastic extension of the limit spring 20 causes the limit spring 20 to squeeze the connecting block 18, thereby causing the sealing ring 17 and the corresponding extrusion ring 4 to return to their initial relative positions.

[0026] As a further embodiment of the present invention, both sides of the adjacent ends of the two sealing rings 17 are fixedly connected to the limit strips 25, and both ends of the two arc-surface clamps 7 are fixedly connected to the plug-in housing 26; When the two arc surface clamps 7 approach and contact each other through the action of the movable component, the arc surface clamps 7 drive the plug-in shell 26 to move synchronously and approach the corresponding limit bar 25, so that the limit bar 25 is located inside the corresponding plug-in shell 26 for limitation. Therefore, when the heating ring 22 heats the inside of the sealing ring 17, the limit bar 25 is located inside the plug-in shell 26 and always limits one end of the sealing ring 17 to one end of the two arc surface clamps 7, ensuring the stability of the contact position between the sealing ring 17 and the arc surface clamp 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 arc surface clamp 7, thereby causing the sealing ring 17 to lose contact with the arc surface clamp 7, thereby reducing accidental leakage of heated gas and ensuring the heating effect of the leveling end of the spring body 49.

[0027] As a further embodiment of the present invention, the feeding assembly comprises: Feeding plate 27 (such as Figure 14 As shown), the loading plate 27 is arranged between the two support bars 5, and a plurality of second arc-shaped grooves 28 are opened on the top of the loading plate 27, and the second arc-shaped grooves 28 are respectively connected to the first arc-shaped grooves 6 at both ends; The fixing plate 29 is fixedly connected to the bottom plate 1, and one side of the fixing plate 29 is fixedly connected to the limiting base 30, and a circular groove 31 is provided on the limiting base 30. The fixing plate 29 is horizontally slidably connected to the first sliding frame 32, and the first sliding frame 32 is vertically slidably connected to the second sliding frame 33. One side of the second sliding frame 33 is fixedly connected to a fixing rod 34, one end of the fixing rod 34 is fixedly connected to the bottom of the loading plate 27, and a fixing pin 35 is fixedly inserted on the fixing rod 34, one end of the fixing pin 35 is fixedly connected to the limiting roller 36, one end of the limiting roller 36 is located inside the circular groove 31, and 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 circular groove 31 and is fixedly connected to a guide bar 38, and a strip groove 39 is provided on the guide bar 38, and the other end of the limiting roller 36 is located inside the strip groove 39, and a second motor 40 is fixedly installed on the fixing plate 29, and the output shaft of the second motor 40 is fixedly connected to the rotating shaft 37; The output shaft of the second motor 40 drives the rotating shaft 37 to rotate, and the rotating shaft 37 drives the guide bar 38 to rotate, and the bar groove 39 on the guide bar 38 is used to limit and guide the limiting roller 36, so that the limiting roller 36 moves unidirectionally along the internal track of the circular groove 31, and drives the fixing rod 34 to move through the connection of the fixing pin 35. During the movement, the fixing rod 34 moves and cooperates with the horizontal sliding of the first sliding frame 32 and the vertical sliding of the second sliding frame 33, and drives the loading plate 27 to reciprocate on the fixed track, and through the limiting effect of the second arc groove 28 on the spring body 49, multiple spring bodies 49 are transported as a whole, so that the spring body 49 can be automatically loaded.

[0028] As a further embodiment of the present invention, one end of the support bar 5 close to the loading direction is fixedly connected to an inclined discharge bar 41, and a collection frame 42 is provided on the bottom plate 1. The collection frame 42 is located below the two inclined discharge bars 41; The loading plate 27 transports the spring body 49 as a whole through the limiting effect of the second arc groove 28 on the spring body 49, and simultaneously transports the leveled spring body 49, so that the leveled spring body 49 moves to the top of the two inclined unloading bars 41, and during the reciprocating movement of the loading plate 27, the support limit of the leveled spring body 49 is released, so that the leveled spring body 49 slides downward along the inclined unloading bar 41 and falls into the collection frame 42, so that the leveled spring body 49 can be automatically unloaded and collected.

[0029] As a further embodiment of the present invention, Figure 15 As shown, a plurality of arc-shaped retaining bars 43 are fixedly connected to the interior of the second arc-shaped groove 28, and the arc-shaped retaining bars 43 are all inclined toward one side; When the spring body 49 is limited by the second arc groove 28 and the first arc grooves 6 on both sides, the arc-shaped baffle 43 inside the second arc groove 28 is located between the two adjacent coils of the spring body 49, so that when the loading plate 27 transports the spring body 49 as a whole, the arc-shaped baffle 43 can limit the spring body 49, thereby preventing the spring body 49 from sliding inside the second arc groove 28, ensuring the stability of the spring body 49 during transportation, and the arc-shaped baffle 43 has the same inclination direction as the coil. When the spring body 49 is placed in the opposite direction inside the second arc groove 28, the arc-shaped baffle 43 cannot enter between the two adjacent coils of the spring body 49, so that the positive and negative spiral directions of the spring body 49 when placed can be distinguished, ensuring the accuracy of the spiral direction of the spring body 49 when placed.

[0030] As a further embodiment of the present invention, the lifting assembly comprises: The lifting bracket 44 is fixedly connected to the bottom plate 1, and the U-shaped bracket 2 is located inside the lifting bracket 44; The second electric cylinder 45 is fixedly mounted on the lifting bracket 44. The transmission shaft of the second electric cylinder 45 is fixedly connected to the U-shaped bracket 2. The U-shaped bracket 2 is fixedly connected to a plurality of first connecting pins 46. The first connecting pins 46 are all slidably inserted into the lifting bracket 44. The U-shaped bracket 2 is driven to move by the transmission 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 moves vertically inside the lifting bracket 44 .

[0031] As a further embodiment of the present invention, the movable component comprises: Two third electric cylinders 47, both of which are fixedly mounted on the lifting bracket 44, with their drive shafts respectively fixedly connected to two arc-surface clamps 7, each of which is fixedly connected to a plurality of second connecting pins 48, each of which is slidably inserted into the lifting bracket 44; The arc surface clamp 7 is driven to move by the transmission shaft of the third electric cylinder 47, and the second connecting pin 48 is moved and limited along the sliding connection of the lifting bracket 44, so that the arc surface clamp 7 moves horizontally, and the two arc surface clamps 7 are moved closer to and away from each other.

[0032] Working principle of the present invention: 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 approach each other by the action of the displacement assembly, so that the two sleeve rods 3 are respectively moved from the two ends of the spring body 49 to the inside of 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. 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. Then, the U-shaped bracket 2 is driven to rise vertically by the action of the lifting component, and the two sleeve rods 3 and the sleeved spring body 49 are driven to rise synchronously between the two arc-surface clamps 7. Then, the angle of the spring body 49 is adjusted by the adjustment component so that the spiral coil of the spring body 49 corresponds to the position of the spiral groove 8 on the arc-surface clamp 7. Then, the two arc-surface clamps 7 are driven to approach each other and contact each other by the action of the movable component, so that the middle part of the spring body 49 is wrapped in the arc-shaped surfaces of the two arc-surface clamps 7, and the middle part of the spring body 49 is limited by the spiral groove 8. Then, the two sleeve rods 3 are driven to continue to approach each other through the action of the displacement component, so that the two extrusion rings 4 respectively squeeze and level the two ends of the spring body 49. 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 at both 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 is reduced under the extrusion action to form a leveling support ring. Finally, the two arc surface clamps 7 are driven away from each other and return to the initial position through the action of the movable component, and then the U-shaped bracket 2 is driven vertically downward through the action of the lifting component, so that the leveled spring body 49 falls back into the corresponding two first arc grooves 6. Then, the two sleeve rods 3 are driven away from each other and return to the initial position through the action of the displacement component, so that the sleeve rod 3 is separated from the inside of the leveled spring body 49, and the spring body 49 in the adjacent first arc grooves 6 is conveyed forward through the action of the loading component, and the leveled spring body 49 is conveyed and separated from the top of the support bar 5, thereby automatically loading the spring body 49 and automatically unloading after processing.
