Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and in particular to a spring winding machine for spring processing that is easy to adjust. Background Technology

[0002] A spring is a part made of elastic material. It works by utilizing elasticity, deforming under the action of external force and returning to its original shape after the external force is removed. Because springs are inexpensive to manufacture, they can be used in various mechanical equipment. Society has a great demand for springs. Springs require the use of a spring winding machine in the processing of springs. The heated spring steel wire is wound and shaped by the spring winding machine.

[0003] Existing technology, such as Chinese Patent Publication No. CN217044434U, discloses an adjustable spring winding machine for precision spring processing. It includes a support plate, an adjusting slide bar frame located at the center of the upper surface of the support plate, and an adjusting groove connected to the outer wall of the adjusting slide bar frame; a limiting frame located outside the adjusting slide bar frame; an adjusting groove formed at one end of the limiting frame; a drive motor connected to the upper surface of the processing frame; a metal connecting sleeve connected below the drive motor; a replaceable winding rod connected below the metal connecting sleeve; a shearing rod located on one side of the replaceable winding rod; and a telescopic rod connected above the shearing rod. This invention effectively stores metal wire material through the set disc wheel frame, facilitating processing; the telescopic rod drives the shearing rod to apply pressure and move for shearing, making it convenient to use; and the replaceable winding rod allows for replacement as needed, thus facilitating the processing of the device. However, this utility model uses multiple bolts to fix the winding rod, and multiple bolts need to be rotated multiple times during loading and unloading, making the replacement process time-consuming and laborious, and indirectly increasing the risk of workers being burned.

[0004] To address the issue of spring winding machines in spring processing not allowing for quick, labor-saving, and safe replacement of winding rollers to adjust spring product specifications, the existing technology mostly uses multiple bolts to fix the winding rollers, requiring multiple bolt rotations for replacement. This makes the loading and unloading process time-consuming and labor-intensive. Furthermore, since the springs are wound after heating, the longer replacement time and more complex process indirectly increase the chances of workers being burned. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing spring winding machines for spring processing are not convenient for quickly, labor-savingly and safely replacing the winding rollers to adjust the specifications of spring products, and to propose a spring winding machine for spring processing that is easy to adjust.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spring winding machine for easy adjustment, comprising a base, a motor, a mounting frame, a winding roller, and a loading and unloading mechanism. The motor is fixedly mounted on the surface of the base, the mounting frame is fixedly connected to the output end of the motor, the winding roller is disposed on the surface of the mounting frame, and the loading and unloading mechanism is disposed on the surface of the mounting frame.

[0007] The loading and unloading mechanism includes a turntable, which is sleeved on the surface of the mounting frame and rotatably connected to the surface of the mounting frame. The inner wall of the turntable is provided with an arc-shaped groove.

[0008] The inner wall of the mounting bracket is slidably connected to a rod, the surface of the spring roller is provided with a hole, the rod is inserted into the surface of the hole, a tension spring is fixedly connected to the surface of the rod, the tension spring is fixedly connected to the inner wall of the mounting bracket, and the rod cooperates with the arc-shaped groove.

[0009] Furthermore, the insertion rod is configured as a "U" shape, the spring roller has different specifications, and there are two sets of arc grooves, insertion rods, insertion holes and tension springs, with the two sets of insertion rods arranged symmetrically.

[0010] Furthermore, the surface of the mounting frame is provided with a positioning groove, and a positioning block is fixedly connected to the surface of the spring roller, and the positioning block is engaged with the surface of the positioning groove.

[0011] Furthermore, the surface of the turntable is provided with anti-slip textures, which are multiple sets and evenly distributed around the circumference, and the surface of the base is provided with clearance grooves.

[0012] Furthermore, an auxiliary mechanism is provided on the surface of the base. The auxiliary mechanism includes a second motor, which is fixedly installed on the surface of the base. A screw is fixedly connected to the output end of the second motor. An adjustment frame is threadedly connected to the surface of the screw. A guide rod is fixedly connected to the surface of the base. The adjustment frame and the guide rod are slidably connected.

[0013] Furthermore, a limiting groove is formed on the surface of the adjusting frame, and a bidirectional threaded rod is rotatably connected to the surface of the limiting groove. A clamping roller is threadedly connected to the surface of the bidirectional threaded rod, and the clamping roller is slidably connected to the surface of the limiting groove. There are two sets of clamping rollers arranged symmetrically.

[0014] Furthermore, a worm gear is rotatably connected to the inner wall of the adjusting frame, and a worm wheel is fixedly connected to the surface of the bidirectional threaded rod, with the worm wheel meshing with the surface of the worm gear.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by setting up a loading and unloading mechanism, starting the motor causes the mounting frame and the coiled spring roller to rotate, and the workpiece is processed by coiling spring. When it is necessary to change to a coiled spring roller of different specifications, simply rotate the turntable, use the arc groove to squeeze the insertion rod, and tighten the tension spring to make the insertion rod disengage from the insertion hole. The coiled spring roller can then disengage from the mounting frame and fall into the relief groove, avoiding direct contact with the operator and preventing burns. Insert the new coiled spring roller into the mounting frame, align the positioning block with the positioning groove, and at this time the insertion rod and the insertion hole are in the corresponding position. Release the turntable, and under the rebound action of the tension spring, the insertion rod returns to its original position and is inserted into the insertion hole to fix the coiled spring roller. Compared with the bolt connection method, the operation process is shorter, less labor-intensive, and safer. By setting up a loading and unloading mechanism, the coiled spring roller can be replaced quickly, labor-intensively, and safely. By changing to coiled spring rollers of different lengths and diameters, the finished size of the workpiece can be adjusted, which effectively improves the convenience of the equipment.

[0017] 2. In this utility model, by setting an auxiliary mechanism, starting the second motor to rotate the screw allows the adjusting frame to slide up and down along the guide rod. Combined with the rotation of the spring-winding roller, this facilitates the spring-winding operation. Furthermore, two sets of clamping rollers can be used to clamp workpieces of different sizes to maintain stable conveying. Simply rotating the worm gear causes the worm wheel to drive the bidirectional threaded rod, allowing the two sets of clamping rollers to move towards or away from each other along the limiting groove. The self-locking function of the worm wheel and worm gear achieves stable clamping. By setting an auxiliary mechanism, two sets of clamping rollers can be used to clamp workpieces of different sizes for stable conveying. Moreover, the adjustable frame, which can move up and down, combined with the rotation of the spring-winding roller, allows for better spring-winding of the workpiece, effectively improving the applicability of the equipment.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a spring winding machine for easy adjustment of springs, including a base 1, a motor 2, a mounting frame 3, a spring winding roller 4, and a loading and unloading mechanism 5. The motor 2 is fixedly mounted on the surface of the base 1, the mounting frame 3 is fixedly connected to the output end of the motor 2, the spring winding roller 4 is disposed on the surface of the mounting frame 3, and the loading and unloading mechanism 5 is disposed on the surface of the mounting frame 3.

[0026] The specific setup and function of its loading and unloading mechanism 5 and auxiliary mechanism 6 will be explained below.

[0027] In this implementation scheme: the loading and unloading mechanism 5 includes a turntable 51, which is sleeved on the surface of the mounting frame 3 and rotatably connected to the surface of the mounting frame 3. The inner wall of the turntable 51 is provided with an arc-shaped groove 52.

[0028] The inner wall of the mounting bracket 3 is slidably connected with a rod 53, and the surface of the spring roller 4 is provided with a hole 54. The rod 53 is inserted into the surface of the hole 54. A tension spring 55 is fixedly connected to the surface of the rod 53. The tension spring 55 is fixedly connected to the inner wall of the mounting bracket 3. The rod 53 cooperates with the arc groove 52.

[0029] The effects achieved by the above components are as follows: the turntable 51 and the arc groove 52 are provided so that when the turntable 51 is rotated, the arc groove 52 can be used to squeeze the insertion rod 53 and tighten the tension spring 55 at the same time, so that the insertion rod 53 can be disengaged from the insertion hole 54. The insertion rod 53 and the insertion hole 54 are provided to facilitate the fixing of the spring roller 4. The tension spring 55 is provided so that the insertion rod 53 can be locked in the insertion hole 54, and its rebound effect can also facilitate the reset of the insertion rod 53.

[0030] Specifically, the insertion rod 53 is set in a "U" shape, the spring roller 4 is set in different specifications, and there are two sets of arc groove 52, insertion rod 53, insertion hole 54 and tension spring 55. The two sets of insertion rod 53 are arranged symmetrically.

[0031] The effects achieved by the above components are as follows: the insertion rod 53 is set in a "U" shape so that one end can be inserted into the insertion hole 54 and the other end can be matched with the arc groove 52; the spring roller 4 is provided with different specifications so that the size of the finished spring can be adjusted by replacing the spring roller 4 with different specifications; and the two sets of insertion rods 53 are provided to increase the stability of the structure.

[0032] Specifically, the surface of the mounting bracket 3 is provided with a positioning groove 56, and the surface of the spring roller 4 is fixedly connected with a positioning block 57, which is engaged with the surface of the positioning groove 56.

[0033] The effect achieved by the above components is as follows: the positioning groove 56 and the positioning block 57 are set so that when the positioning block 57 corresponds to the positioning groove 56, the insertion hole 54 also corresponds to the insertion rod 53, which makes it easy to quickly find the position and avoids the situation that the insertion hole 54 and the insertion rod 53 are not easy to align.

[0034] Specifically, the surface of the turntable 51 is provided with anti-slip textures 58, which are multiple sets and evenly distributed around the circumference, and the surface of the base 1 is provided with clearance grooves 59.

[0035] The effects achieved by the above components are as follows: the anti-slip texture 58 is set to increase friction and prevent slippage when rotating the turntable 51; the relief groove 59 is set to allow the spring roller 4 to fall directly into the relief groove 59 after being removed for subsequent cooling operations, so as not to come into direct contact with the operator and reduce the chance of burns.

[0036] Specifically, an auxiliary mechanism 6 is provided on the surface of the base 1. The auxiliary mechanism 6 includes a second motor 61, which is fixedly installed on the surface of the base 1. A screw 62 is fixedly connected to the output end of the second motor 61. An adjusting frame 63 is threadedly connected to the surface of the screw 62. A guide rod 64 is fixedly connected to the surface of the base 1. The adjusting frame 63 and the guide rod 64 are slidably connected.

[0037] The effects achieved by the above components are as follows: When the second motor 61, screw 62 and adjusting frame 63 are set up, the adjusting frame 63 can move up and down along the guide rod 64 when the second motor 61 is started and the screw 62 is rotated, so as to cooperate with the rotation of the spring roller 4 and make the spring better formed. The guide rod 64 is set up to provide guidance and limit the movement of the adjusting frame 63 and prevent it from rotating with the screw 62.

[0038] Specifically, a limiting groove 65 is provided on the surface of the adjusting frame 63, a bidirectional threaded rod 66 is rotatably connected to the surface of the limiting groove 65, a clamping roller 67 is threadedly connected to the surface of the bidirectional threaded rod 66, the clamping roller 67 is slidably connected to the surface of the limiting groove 65, and there are two sets of clamping rollers 67 arranged symmetrically.

[0039] The effects achieved by the above components are as follows: the limiting groove 65 provides guidance and limiting for the movement of the clamping roller 67, preventing it from rotating with the bidirectional threaded rod 66; the bidirectional threaded rod 66 and the two sets of clamping rollers 67 are provided so that when the bidirectional threaded rod 66 rotates, the two sets of clamping rollers 67 can move towards each other or away from each other, thereby realizing the clamping and conveying of spring steel wires of different sizes.

[0040] Specifically, a worm gear 68 is rotatably connected to the inner wall of the adjusting frame 63, and a worm wheel 69 is fixedly connected to the surface of the bidirectional threaded rod 66, with the worm wheel 69 meshing with the surface of the worm gear 68.

[0041] The effect achieved by the above components is as follows: the worm 68 and worm wheel 69 are set so that when the worm 68 is rotated, the worm wheel 69 drives the bidirectional threaded rod 66 to rotate, and the self-locking function of the worm wheel 69 and worm 68 is used to prevent the clamping roller 67 from moving arbitrarily.

[0042] Working principle: By setting up the loading and unloading mechanism 5, starting the motor 2 causes the mounting frame 3 and the coiled roller 4 to rotate, performing coiling processing on the workpiece. When it is necessary to change to a different specification of coiled roller 4, simply rotate the turntable 51, using the arc groove 52 to squeeze the insertion rod 53, tightening the tension spring 55 while simultaneously causing the insertion rod 53 to disengage from the insertion hole 54. The coiled roller 4 can then detach from the mounting frame 3 and fall into the relief groove 59, avoiding direct contact with the operator and preventing burns. Insert the new coiled roller 4 into the mounting frame 3, so that the positioning block 57 aligns with the positioning... With slot 56 aligned, the insertion rod 53 and insertion hole 54 are in corresponding positions. The turntable 51 is released, and the insertion rod 53 is reset under the rebound action of the tension spring 55 and inserted into the insertion hole 54 to fix the coiled roller 4. Compared with the bolt connection method, the operation process is shorter, less effort, and safer. By setting the loading and unloading mechanism 5, the coiled roller 4 can be replaced quickly, effortlessly, and safely. By replacing the coiled roller 4 with different lengths and diameters, the finished product size of the workpiece can be adjusted, which effectively improves the convenience of the equipment.

[0043] Furthermore, by setting up an auxiliary mechanism 6, starting the motor 61 causes the screw 62 to rotate, which allows the adjusting frame 63 to slide up and down along the guide rod 64. In conjunction with the rotation of the spring winding roller 4, it is more conducive to the spring winding operation. Moreover, two sets of clamping rollers 67 can be used to clamp workpieces of different sizes to maintain stable conveying. Simply rotate the worm 68 to make the worm wheel 69 drive the bidirectional threaded rod 66 to rotate, so that the two sets of clamping rollers 67 can move towards each other or away from each other along the limiting groove 65. The self-locking function of the worm wheel 69 and worm 68 is used to achieve stable clamping. By setting up the auxiliary mechanism 6, two sets of clamping rollers 67 can be used to clamp workpieces of different sizes for stable conveying. In addition, the adjustable frame 63, which can move up and down, in conjunction with the rotation of the spring winding roller 4, allows the workpiece to be wound better, which effectively improves the applicability of the equipment.
