Twill spring receiving rack

Abstract

This utility model discloses a helical spring receiving rack, relating to the field of spring manufacturing technology. The helical spring receiving rack includes a frame with a constraint space. The constraint space has an inlet on the side near the discharge end and an outlet on the side away from the discharge end. Helical springs extending from the discharge end of the spring machine enter the constraint space through the inlet. The constraint space constrains and restricts the helical springs extending from the discharge end and completed winding, thus preventing the helical springs away from the discharge end from swaying excessively due to the rotational force of the spring machine's rotating mechanism when rotating synchronously with it, which could lead to deformation. The constraint space not only restricts the swaying of the helical springs but also supports them, preventing sagging or deformation due to their own weight. This significantly improves the production quality and stability of the helical springs.

Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a helical spring receiving rack. Background Technology

[0002] In the manufacturing process of helical springs, rotation is required to achieve a specific helical angle and shape. When winding helical springs, the rotation mechanism of the spring machine is programmed to rotate the spring material at a specific angle and direction during the winding process, thereby realizing the manufacturing of helical springs. Currently, when manufacturing longer helical springs, the portion of the helical spring that has already been wound and extends from the discharge end of the spring machine will rotate synchronously under the action of the spring machine's rotation mechanism. This causes the helical spring that has been wound and is far from the discharge end to be subject to a large rotational force, resulting in a large amplitude of oscillation, which can easily cause deformation and affect production quality. Utility Model Content

[0003] The main purpose of this invention is to propose a shear spring receiving rack, which aims to improve the problem that shear springs far from the discharge end are prone to large-amplitude swings during the current shear spring manufacturing process, thus affecting production quality.

[0004] To achieve the above objectives, this utility model proposes a helical spring receiving rack, having an X-direction extending along its length, for use at the discharge end of a spring machine to receive springs, comprising:

[0005] The frame has a constraint space extending along the X direction, and the constraint space is arranged corresponding to the discharge end in the X direction;

[0006] The constrained space has an inlet on one side along the X direction and an outlet on the other side along the X direction; the inlet is located near the discharge end and is correspondingly arranged to the discharge end.

[0007] In one embodiment, the helical spring receiving rack further includes a hollow tube disposed on the rack body and extending along the X direction;

[0008] The internal space of the hollow tube constitutes the constrained space, and the hollow tube has openings on both sides along the X direction that communicate with the outside.

[0009] The opening on the side closer to the discharge end constitutes the inlet, and the opening on the side farther from the discharge end constitutes the outlet.

[0010] In one embodiment, the inner diameter of the hollow tube is consistent with the outer diameter of the spring.

[0011] In one embodiment, the hollow tube is rotatably mounted on the frame;

[0012] The shear spring receiving frame also includes a driving component, which is mounted on the frame body and is used to drive the hollow tube to rotate relative to the frame body;

[0013] The rotation direction of the hollow tube is the same as the rotation direction of the helical spring extending from the discharge end.

[0014] In one embodiment, the rotational speed at which the driving member drives the hollow tube relative to the frame is denoted as V1, and the rotational speed of the helical spring extending from the discharge end is denoted as V2, wherein V1 and V2 are kept consistent.

[0015] In one embodiment, the drive element includes:

[0016] The drive unit is mounted on the frame; and

[0017] A transmission mechanism is provided, wherein the driving unit drives the hollow tube to rotate via the transmission mechanism; the transmission mechanism has an input end connected to the driving unit and an output end connected to the hollow tube, wherein the rotational speed of the output end is greater than the rotational speed of the input end.

[0018] In one embodiment, the transmission mechanism includes:

[0019] The first pulley is driven by the drive unit; and

[0020] The second pulley rotates coaxially with the hollow tube;

[0021] A belt is used to connect the first pulley and the second pulley. The drive unit drives the hollow tube to rotate via the first pulley, the belt, and the second pulley. The diameter of the first pulley is larger than the diameter of the second pulley. The first pulley forms the input end and the second pulley forms the output end.

[0022] In one embodiment, the herringbone spring receiving rack further includes:

[0023] The mounting base has multiple mounting bases, which are fixedly mounted to the frame at intervals along the X-direction; and

[0024] A bearing is provided corresponding to the mounting base, and the bearing is housed in the corresponding mounting base. The inner ring of the bearing is coaxially sleeved on the outer periphery of the hollow tube.

[0025] In one embodiment, the outer periphery of the hollow tube is interference-fitted with the inner ring of the bearing.

[0026] In one embodiment, the herringbone spring receiving frame further includes a set of casters, which is mounted on the bottom of the frame.

[0027] This utility model relates to a sheared spring receiving rack, which includes a frame with a constraint space. The constraint space has an inlet on the side near the discharge end and an outlet on the side away from the discharge end. The sheared spring extending from the discharge end of the spring machine enters the constraint space through the inlet. The constraint space constrains and restricts the sheared spring extending from the discharge end and completing its winding, thus preventing the sheared spring away from the discharge end from swinging excessively due to the rotational force of the spring machine's rotating mechanism when it rotates synchronously with the spring machine's rotating mechanism, which could lead to deformation. The constraint space not only restricts the swinging of the sheared spring but also supports it, preventing it from sagging or deforming due to its own weight. This significantly improves the production quality and stability of the sheared spring. Attached Figure Description

[0045] In the manufacturing process of helical springs, rotation is required to achieve a specific helical angle and shape. When winding helical springs, the rotation mechanism of the spring machine is programmed to rotate the spring material at a specific angle and direction during the winding process, thereby realizing the manufacturing of helical springs. Currently, when manufacturing longer helical springs, the portion of the helical spring that has already been wound and extends from the discharge end of the spring machine will rotate synchronously under the action of the spring machine's rotation mechanism. This causes the helical spring that has been wound and is far from the discharge end to be subject to a large rotational force, resulting in a large amplitude of oscillation, which can easily cause deformation and affect production quality.

[0046] Based on this, refer to Figure 1 , Figure 3 , Figure 6 As shown, this application embodiment provides a helical spring receiving rack. The helical spring receiving rack has an X-direction extending along its length, which is used to receive springs at the discharge end 71 of the spring machine 7. It can be understood that the X-direction in this solution should be the discharge direction of the spring wound by the spring machine 7. The helical spring receiving rack includes a frame body 1, and the frame body 1 has a constraint space 21 extending along the X-direction, such as... Figure 5 As shown, in the X direction, the constraint space 21 has an inlet 212 on one side and an outlet 211 on the other side. The inlet 212 is located near the discharge end 71. The constraint space 21 is connected to the outside world through the inlet 212 and the outlet 211. The inlet 212 is correspondingly set to the discharge end 71 of the spring machine 7, thereby ensuring that the shear spring 6 sent from the discharge end 71 can accurately enter the constraint space 21 through the inlet 212. It can be understood that the shear spring 6 away from the discharge end 71 moves out of the constraint space 21 through the outlet 211.

[0047] It is understandable that, such as Figure 6 As shown, when the helical spring 6 is fed out from the discharge end 71 of the spring machine 7 (at this time, the helical spring 6 rotates synchronously under the action of the rotating mechanism inside the spring machine 7), the rotating mechanism is necessary during the process of the spring machine 7 winding the helical spring 6 to ensure that the spring is wound according to the predetermined helical angle and shape.

[0048] In this embodiment, when the shear spring 6, which is fed outward from the discharge end 71 of the spring machine 7, enters the constraint space 21 through the inlet 212, the constraint space 21 constrains and restricts the shear spring 6 fed out from the discharge end 71 of the spring machine 7. Due to the restriction of the constraint space 21, the part of the shear spring 6 away from the discharge end 71 will not swing significantly due to the rotational force of the rotating mechanism of the spring machine 7. The constraint space 21 can effectively suppress the swing of the shear spring 6 away from the discharge end 71, thereby effectively avoiding the situation where the shear spring 6 fed out from the discharge end 71 swings significantly on the side away from the discharge end 71 when rotating with the rotating mechanism of the spring machine 7, which could easily lead to deformation.

[0049] In this embodiment, the constraint space 21 not only limits and constrains the end of the helical spring 6 (that is, the side of the helical spring 6 away from the discharge end 71 of the spring machine 7), but also supports the helical spring 6, preventing the helical spring 6 sent from the discharge end 71 from being too long and drooping due to its own gravity, thereby significantly improving the production quality and stability of the helical spring 6.

[0050] Reference Figure 1 , Figure 3 , Figure 5 As shown, in one embodiment of this application, the shear spring receiving rack further includes a hollow tube 2, which is mounted on the frame 1 and extends along the X direction; as Figure 5 As shown, the internal space of the hollow tube 2 forms the aforementioned constraint space 21, and the hollow tube 2 has openings at both ends along the X direction that communicate with the outside. The opening on the side closer to the discharge end 71 forms the aforementioned inlet 212, which is used to allow the shear spring 6 to enter the constraint space 21 from the discharge end 71. The opening on the side away from the discharge end 71 forms the aforementioned outlet 211, which is used to allow the completed shear spring 6 to move outward from the outlet 211.

[0051] Understandably, the height of the hollow tube 2 installed on the frame 1 should match the height of the discharge end 71 of the spring machine 7, so that the discharge end 71 of the spring machine 7 can correspond to the inlet 212 located on the side of the hollow tube 2 near the discharge end 71. This allows the shear spring 6 sent from the discharge end 71 to accurately enter the constraint space 21. During the rotation of the shear spring 6 driven by the rotation mechanism of the spring machine 7, the shear spring 6 entering the constraint space 21 will be constrained and restricted by the inner wall of the hollow tube 2, thereby suppressing the swing amplitude of the shear spring 6 away from the discharge end 71, thus reducing the probability of the shear spring 6 deforming.

[0052] Reference Figure 6As shown in one embodiment of this application, in order to further improve the constraint and restriction effect on the helical spring 6 entering the constraint space 21, the inner diameter of the hollow tube 2 can be kept consistent with the outer diameter of the spring. This ensures that after the helical spring 6 enters the constraint space 21, its outer surface is tightly fitted with the inner surface of the hollow tube 2. This tight fit can significantly reduce the movement space of the helical spring 6 in the constraint space 21. When the helical spring 6 is tightly fitted with the inner surface of the hollow tube 2, the movement of the helical spring 6 will be more strictly restricted. It cannot swing in the hollow tube 2, thereby effectively avoiding the swing and deformation caused by the force of the spring machine 7 rotation mechanism.

[0053] Reference Figure 1 , Figure 3 As shown, in one embodiment of this application, the hollow tube 2 is rotatably mounted on the frame 1. The shear spring receiving frame also includes a driving component 3 (the driving component 3 can be a motor, cylinder, or other rotary driving device, whose function is to provide rotational power for the hollow tube 2). The driving component 3 is mounted on the frame 1 and is used to drive the hollow tube 2 to rotate relative to the frame 1. The rotation direction of the hollow tube 2 is the same as the rotation direction of the shear spring 6 delivered from the discharge end 71. It can be understood that in this solution, the shear spring 6 located in the constraint space 21 contacts and cooperates with the inner wall of the hollow tube 2. This creates frictional resistance between the outer periphery of the helical spring 6 and the inner wall of the hollow tube 2. The rotation of the hollow tube 2 synchronously applies a rotational force to the helical spring 6. The direction of this rotational force is the same as the direction of the rotational force applied by the rotating mechanism inside the spring machine 7. Therefore, the rotational force provided by the hollow tube 2 assists the helical spring 6 in rotating, thereby appropriately reducing the rotational force applied by the rotating mechanism of the spring machine 7. This means the rotating mechanism of the spring machine 7 does not need to provide all the rotational force, thus reducing its load.

[0054] In this embodiment, the rotational force applied by the rotating mechanism of the spring machine 7 is reduced, thereby further reducing the swing amplitude of the shear spring 6 on the side away from the discharge end 71. This is because the rotational force applied to the shear spring 6 by the rotating mechanism of the spring machine 7 is far from the end of the shear spring 6. The greater the rotational force applied by the rotating mechanism of the spring machine 7, the greater the amplitude of the change at the end of the shear spring 6. In this embodiment, the rotation of the hollow tube 2 is used to compensate for the rotational mechanism of the spring machine 7 to a certain extent, thereby appropriately reducing the rotational force applied by the rotating mechanism of the spring machine 7, further reducing the swing amplitude at the end of the shear spring 6, and ensuring that the shear spring 6 is more stable during the discharge process.

[0055] In one embodiment of this application, the rotational speed of the hollow tube 2 relative to the frame 1 driven by the drive member 3 is denoted as V1, and the rotational speed of the spring extending from the discharge end 71 is denoted as V2. V1 and V2 are kept consistent. The rotational speed of the hollow tube 2 driven by the drive member 3 is consistent with the rotational speed of the helical spring 6 driven by the rotating mechanism. This ensures that the rotation of the hollow tube 2 and the rotation of the helical spring 6 are completely synchronized. While satisfying the requirement to assist in driving the helical spring 6 to rotate, it also avoids the uneven rotational force between the part of the helical spring 6 in the constrained space 21 and the part of the helical spring 6 at the discharge end 71 due to the excessive rotational speed of the hollow tube 2. That is, the rotational speed mismatch causes the helical spring 6 to deform or wear.

[0056] Reference Figure 2 As shown, in one embodiment of this application, the driving component 3 includes a driving part 31 and a transmission mechanism 32. The driving part 31 can be a motor or other rotary driving device, and its function is to provide rotational power to the hollow tube 2. The driving part 31 is fixedly installed on the frame 1 at a suitable position. The transmission mechanism 32 is used to realize the connection between the driving part 31 and the hollow tube 2 and to realize the transmission of power. The transmission mechanism 32 has an input end connected to the driving part 31 and an output end connected to the hollow tube 2, and the speed of the output end is greater than the speed of the input end. This is set up to realize the conversion of the motor speed to a relatively higher speed (which can appropriately reduce the operating power of the motor to a certain extent) and to drive the hollow tube 2 to rotate, so that the speed of the hollow tube 2 can be matched with the speed of the rotation mechanism of the spring machine 7.

[0057] It is understood that the drive unit 31 (motor) in this embodiment is a servo motor (connected to an external power source). The servo motor can achieve high-precision speed control through its built-in feedback system (such as an encoder) and controller, thereby ensuring that the speed of the hollow tube 2 and the rotation speed of the spring machine 7 are consistent. At the same time, the servo motor can flexibly adjust its speed according to different processing requirements. For example, under different production batches or different specifications of the shear spring 6, the speed of the servo motor can be changed by programming or manually adjusting the control signal. This enables the shear spring receiving rack to adapt to various production scenarios and improves the versatility and applicability of the equipment.

[0058] Reference Figure 2 As shown, in one embodiment of this application, the transmission mechanism 32 includes a first pulley 321, a second pulley 322, and a belt 323. The first pulley 321 is driven by the drive unit 31, that is, the first pulley 321 is coaxially mounted on the output shaft of the drive unit 31. The second pulley 322 rotates coaxially with the hollow tube 2. The belt 323 is connected between the first pulley 321 and the second pulley 322, and is used to transmit the power output by the drive unit 31 to the hollow tube 2, thereby driving the hollow tube 2 to rotate.

[0059] In this embodiment, the diameter of the first pulley 321 is larger than the diameter of the second pulley 322, thereby increasing the output speed of the motor and driving the hollow tube 2 to rotate at a higher speed. By setting the first pulley 321 and the second pulley 322, the operating power of the motor can be appropriately reduced to a certain extent while ensuring that the hollow tube 2 rotates at the same speed.

[0060] Reference Figure 4 As shown in one embodiment of this application, the helical spring receiving rack further includes a mounting base 4 and a bearing; wherein, there are multiple mounting bases 4, and the multiple mounting bases 4 are fixedly installed on the frame body 1 at intervals along the X direction; the bearing is correspondingly arranged with the mounting base 4, and the bearing is housed in the corresponding mounting base 4; it can be understood that the outer ring of the bearing is rotatably installed in the mounting base 4, and the inner ring of the bearing is coaxially sleeved on the outer periphery of the hollow tube 2.

[0061] In this embodiment, multiple bearings arranged at intervals along the X direction are used to position the entire hollow tube 2, in order to prevent the hollow tube 2 from shaking during high-speed rotation.

[0062] In one embodiment of this application, the outer periphery of the hollow tube 2 is interference-fitted with the inner ring of the bearing, thereby ensuring a tight fit between the outer periphery of the hollow tube 2 and the inner ring of the bearing, achieving a stable connection.

[0063] Reference Figure 1 , Figure 3 As shown in one embodiment of this application, the helical spring receiving rack also includes a caster assembly, which includes multiple casters 5. Each caster 5 is installed at the bottom of the frame 1 and at a diagonal position, thereby making the movement of the frame 1 more convenient. It should be noted that the casters 5 in this solution need to be casters with a self-locking function, so that after the receiving rack reaches the designated position, the casters 5 can be locked to prevent it from moving, thereby ensuring the stability of the receiving rack. Since casters with a self-locking function are widely available and commonly used components in the market (belonging to the prior art), their structural principle will not be described in detail here.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
