Description

Technical Field

[0001] This utility model relates to the technical field of spring processing, specifically a fixing component for spring processing. Background Technology

[0002] Although the spring industry is a small sector within the overall manufacturing industry, its role is absolutely invaluable. As the country's industrial manufacturing and automotive industries need to accelerate their development, the spring industry, as one of the basic components and parts, needs to have an advanced development trajectory to adapt to the rapid development of the entire national industry.

[0003] Springs play an important role. In the production and processing of springs, steel wire is usually selected to be processed into spiral coils. After the springs are formed, they need to be cut into segments of equal distance to form finished springs.

[0004] When processing springs, no fixing device is usually added. Therefore, as the spring changes with the force applied during processing, spring misalignment may occur, which increases the spring adjustment time.

[0005] Therefore, a fixing component for spring processing is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A fixing component for spring processing according to this utility model includes a base, a servo motor fixedly connected to the bottom of the base; a first round rod fixedly connected to the output end of the servo motor; the first round rod is through-hole and rotatably connected to the base; a connecting plate is fixedly connected to the top of the first round rod; multiple first connecting rods are fixedly connected to the surface of the connecting plate; a first fixing rod is rotatably connected to the middle of the first connecting rod; multiple sliders are slidably connected to the surface of the base; a second connecting rod is fixedly connected to the top of the slider; the first fixing rod and the second connecting rod are rotatably connected; a support rod is fixedly connected to the middle of the slider; a shell is fixedly connected to the surface of the base; the support rod is slidably connected to the shell; by adding a support rod, the torsion caused by the force on the spring during processing can be reduced, thereby increasing the stability during spring processing. At the same time, only the rotation of the connecting plate is needed to drive the support rod to fix the spring, thereby reducing the movement of the spring during processing.

[0008] Preferably, a second round rod is fixedly connected to the middle of the outer casing; a first bolt is threaded to the top of the second round rod; by adding the first bolt, the spring can be initially fixed before the support rod is used, thereby reducing the movement of the spring when it is fixed, thereby increasing the stability of the spring when it is fixed.

[0009] Preferably, a plurality of locking blocks are fixed to the surface of the support rod; the inner wall of the locking blocks is arc-shaped; by adding locking blocks, the deformation capability of the locking blocks can be used to increase the contact between the support rod and the spring when the support rod is fixed to the spring, thereby increasing the friction between the support rod and the spring.

[0010] Preferably, the end of the second round rod is threaded with a second bolt; the second bolt is located above the first bolt; by adding the second bolt, the friction of the threaded fixing of the second bolt can be utilized, thereby reducing the loosening of the first bolt and increasing the stability of the spring fixing.

[0011] Preferably, a plurality of second fixing rods are fixedly connected to the top of the second bolt; a handle is rotatably connected to the end of the second fixing rod; by adding a handle, the control of the second bolt can be increased when installing the second bolt, so that the second bolt can be quickly rotated by the handle during installation, thereby speeding up the installation.

[0012] Preferably, a rubber pad is fixed to the bottom of the first bolt; the rubber pad and the first bolt are correspondingly arranged; by adding the rubber pad, the direct contact between the spring and the first bolt can be reduced, thereby increasing the protection of the spring.

[0013] The advantages of this utility model are:

[0014] 1. The fixing component for spring processing described in this utility model can reduce the torsion of the spring during processing by adding a support rod, thereby increasing stability during spring processing. At the same time, the support rod can be driven to fix the spring simply by rotating the connecting plate, thereby reducing spring movement during processing.

[0015] 2. The spring processing fixing assembly of this utility model can preliminarily fix the spring before using the support rod by adding a first bolt, thereby reducing the movement of the spring when it is fixed and increasing the stability of the spring when it is fixed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a fixing assembly for spring processing includes a base 1, a servo motor 11 fixedly connected to the bottom of the base 1; a first round rod 12 fixedly connected to the output end of the servo motor 11; the first round rod 12 is through-hole and rotatably connected to the base 1; a connecting plate 13 fixedly connected to the top of the first round rod 12; a plurality of first connecting rods 14 fixedly connected to the surface of the connecting plate 13; a first fixing rod 15 rotatably connected to the middle of the first connecting rod 14; a plurality of sliders 16 slidably connected to the surface of the base 1; a second connecting rod 17 fixedly connected to the top of the slider 16; the first fixing rod 15 and the second connecting rod 17 are rotatably connected; a support rod 18 fixedly connected to the middle of the slider 16; a housing 19 fixedly connected to the surface of the base 1; the support rod 18 is slidably connected to the housing 19; during operation, the servo motor 11 is first started to drive the first round rod 12 to... When the first round rod 12 rotates, it drives the connecting plate 13 to rotate. When the connecting plate 13 rotates, it drives the first connecting rod 14 to move. At the same time, the first connecting rod 14 drives the first fixed rod 15 to rotate. When the first fixed rod 15 rotates, it pulls the slider 16 to slide. At the same time, the connection between the first fixed rod 15 and the base 1 also rotates, thereby driving the support rod 18 to move closer to the center. Then, the spring is sleeved on the outer wall of the support rod 18. Then, the servo motor 11 is started to drive the support rod 18 to spread and move closer to the spring. After the support rod 18 contacts the spring, it will be tightly attached to the spring, thereby fixing it from the inside of the spring. By adding the support rod 18, the torsion of the spring caused by the force during processing can be reduced, thereby increasing the stability during spring processing. At the same time, only the rotation of the connecting plate 13 is needed to drive the support rod 18 to fix the spring, thereby reducing the movement of the spring during processing.

[0026] like Figures 1 to 4 As shown, a second round rod 2 is fixedly connected to the middle of the outer shell 19; a first bolt 21 is threadedly connected to the top of the second round rod 2; during operation, the spring is first sleeved on the support rod 18, and then the first bolt 21 can be rotated and installed on the second round rod 2, so that the first bolt 21 and the spring come into contact. As the first bolt 21 moves down, it will come into contact with the spring, and then a partial thrust will be generated on the spring. At this time, the rotation of the first bolt 21 can be stopped, and then the support rod 18 can continue to support and fix the spring. When the support rod 18 supports and fixes the spring, the first bolt 21 will assist the support rod 18 in fixing the spring; by adding the first bolt 21, the spring can be initially fixed before the support rod 18 is used, thereby reducing the movement of the spring when it is fixed, thereby increasing the stability when the spring is fixed.

[0027] like Figures 1 to 3As shown, multiple locking blocks 3 are fixedly attached to the surface of the support rod 18; the inner wall of the locking block 3 is arc-shaped; during operation, when the support rod 18 approaches the spring, it will drive the locking blocks 3 to move together. When the support rod 18 contacts the spring, the locking blocks 3 will also contact the spring. Subsequently, the end of the locking block 3 will be squeezed and deformed due to the movement of the support rod 18, so that when it contacts the spring, it will cause the spring to sink into the locking block 3, thereby increasing the contact between the support rod 18 and the spring; by adding locking blocks 3, the deformation ability of the locking blocks 3 can be used to increase the contact between the support rod 18 and the spring when the support rod 18 is fixed to the spring, thereby increasing the friction between the support rod 18 and the spring.

[0028] like Figures 1 to 4 As shown, the second round rod 2 has a threaded connection to the end of a second bolt 4; the second bolt 4 is located above the first bolt 21; during operation, after the spring is fixed with the first bolt 21, the second bolt 4 can be installed on the second round rod 2 again, and then the first bolt 21 can be fixed with the second bolt 4 when fixing the spring. Thus, when fixing the spring with the first bolt 21, the second bolt 4 is added to increase the fixation of the first bolt 21; by adding the second bolt 4, the friction of the threaded fixing of the second bolt 4 can be used to reduce the loosening of the first bolt 21 and increase the stability when fixing the spring.

[0029] like Figure 4 As shown, a plurality of second fixing rods 5 are fixedly connected to the top of the second bolt 4; a handle 51 is rotatably connected to the end of the second fixing rod 5; during operation, the second bolt 4 can be installed by rotating the handle 51, thereby installing the second bolt 4. When the handle 51 is rotated, it will push the second bolt 4 to rotate and gradually move downward, thus contacting the first bolt 21; by adding the handle 51, the control of the second bolt 4 can be increased when installing the second bolt 4, so that the second bolt 4 can be quickly rotated by the handle 51, thus speeding up the installation.

[0030] like Figure 4 As shown, a rubber pad 6 is fixed to the bottom of the first bolt 21; the rubber pad 6 and the first bolt 21 are correspondingly arranged; during operation, when the first bolt 21 is used to fix the spring, the end of the spring will first contact the rubber pad 6, thereby reducing the friction between the first bolt 21 and the spring, thereby reducing the damage to the spring; by adding the rubber pad 6, the direct contact between the spring and the first bolt 21 can be reduced, thereby increasing the protection of the spring.

[0031] Working principle: First, the servo motor 11 is started, causing the first round rod 12 to rotate. When the first round rod 12 rotates, it drives the connecting plate 13 to rotate. When the connecting plate 13 rotates, it drives the first connecting rod 14 to move. At the same time, the first connecting rod 14 drives the first fixed rod 15 to rotate. When the first fixed rod 15 rotates, it pulls the slider 16 to slide. At the same time, the connection between the first fixed rod 15 and the base 1 also rotates, thereby driving the support rod 18 closer to the center. Then, the spring is sleeved on the outer wall of the support rod 18, and then the servo... The motor 11 starts, driving the support rod 18 to spread out and approach the spring. Once the support rod 18 contacts the spring, it will press tightly against the spring, thus fixing it from the inside. After first fitting the spring onto the support rod 18, the first bolt 21 can be rotated and installed onto the second round rod 2, making the first bolt 21 contact the spring. As the first bolt 21 moves downwards, it will contact the spring, generating a partial thrust. At this point, the rotation of the first bolt 21 can be stopped, and the support rod 18 can continue to support and fix the spring. During support and fixation, the first bolt 21 assists the support rod 18 in fixing the spring. As the support rod 18 approaches the spring, it moves the locking block 3 along with it. When the support rod 18 contacts the spring, the locking block 3 also contacts the spring. Subsequently, the end of the locking block 3 is compressed and deformed due to the movement of the support rod 18, thus trapping the spring inside the locking block 3 when it contacts the spring, thereby increasing the contact between the support rod 18 and the spring. After fixing the spring with the first bolt 21, the second bolt 4 can be installed on the second round rod 2. Subsequently, when fixing the spring, the second bolt 4 can be used to fix it. Bolt 4 secures the first bolt 21, thus adding a second bolt 4 to further secure the first bolt 21 when using the first bolt 21 to fix the spring. When installing the second bolt 4, it can be installed by rotating the handle 51. Rotating the handle 51 will push the second bolt 4 to rotate and gradually move it downwards, thereby contacting the first bolt 21. When using the first bolt 21 to fix the spring, the end of the spring will first contact the rubber pad 6, thereby reducing the friction between the first bolt 21 and the spring and thus reducing damage to the spring.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
