Description

Technical Field

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

[0002] A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is generally made of spring steel.

[0003] After the spring is manufactured, depending on product requirements, its cross-section may need to be cut flat. Therefore, it needs to be fixed with a clamp first, and then cut with a cutting machine or laser to make the cross-section flat. Existing clamping clamps mostly use two sets of clamping plates for holding, which has a simple clamping structure, but poor clamping stability. During the cutting process, the spring is prone to shaking, which affects the flatness of the cross-section. This requires repeated processing such as grinding afterward, which is quite troublesome. To solve this problem, we propose a fixing component for spring cutting. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing component for spring cutting, so as to solve the problem of existing fixing clamps mentioned in the background art, which mostly use two sets of clamping plates for clamping. The clamping structure is simple, but the clamping stability is poor, and the spring is prone to shaking during the cutting process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing component for spring cutting processing, including a base, a column fixedly welded to the upper end of the base, a central screw fixedly arranged horizontally on the column, a bidirectional screw rotatably installed inside the column, two sets of first threaded sleeves symmetrically sleeved on the bidirectional screw, two sets of sliders slidably arranged inside the column, the two sets of first threaded sleeves respectively fixedly installed in the two sets of sliders, an upper limit rod rotatably installed on the upper slider, and a lower limit rod fixedly installed on the lower slider;

[0006] A sliding sleeve is slidably sleeved on the central screw, and support rods are symmetrically hinged at the upper and lower ends of the sliding sleeve. A second threaded sleeve is threadedly sleeved on the side of the central screw closer to the column. A connecting seat is rotatably installed on the second threaded sleeve. Adjustment components connected to the support rods are provided at both the upper and lower ends of the connecting seat. A limit sleeve is threadedly sleeved on the side of the central screw away from the column.

[0007] Preferably, the upper limit rod and the lower limit rod have the same circular cross-section, and the central screw, the upper limit rod and the lower limit rod are arranged in parallel.

[0008] Preferably, the end of the upper limit rod away from the column is provided with a stop rod, and the stop rod is perpendicular to the upper limit rod. The end of the upper limit rod near the column passes through the slider and is provided with a handle, which is perpendicular to the upper limit rod and is not parallel to the stop rod.

[0009] Preferably, a through groove with a width matching the diameter of the upper limit rod is provided in the middle of the support rod, and the two sets of support rods are respectively sleeved on the upper limit rod and the lower limit rod through the through groove. Baffles are provided on both the front and rear surfaces of the upper support rod.

[0010] Preferably, a knob is fixedly provided at one end of the second screw sleeve near the column, one side surface of the knob is provided with anti-slip texture, and the other side surface of the knob is provided with an octagonal shape.

[0011] Preferably, the adjusting assembly includes a sleeve rod, with the upper and lower ends of the connecting seat symmetrically hinged with sleeve rods. A support screw rod is inserted into the opening of the sleeve rod, and an adjusting screw sleeve is rotatably installed at the opening of the sleeve rod. The adjusting screw sleeve is threaded onto the support screw rod. The outer end of the support screw rod is hinged to the lower side of the support rod. A guide groove is provided on the outer wall of the support screw rod, and a protrusion adapted to the guide groove is provided on the inner wall of the sleeve rod.

[0012] The beneficial effects of this utility model are as follows: By setting an upper limit rod and a lower limit rod to open in opposite directions, the upper limit rod can abut against the inner wall of the spring. In conjunction with the abutment rod and two sets of support rods, the two ends of the spring can be held in place, so that the spring is not easy to move during processing, limiting the possibility of its shaking, thereby ensuring its stability during the cutting process and reducing the unevenness of the cut surface caused by shaking. At the same time, loading and unloading are simple. Just by holding the handle and turning the abutment rod, the spring can be moved up and down from the right side of the device. The operation is convenient and simple. In addition, by adjusting the bidirectional screw and the expansion degree and position of the two sets of support rods, it can be adapted to the processing of springs of different models and lengths. It has strong practicality and a wide range of applications. Attached image description:

Detailed implementation method:

[0021] 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 protection scope of the present utility model.

[0022] Please see Figure 1-6 An embodiment of this utility model provides a fixing component for spring cutting processing, including a base 1, a column 2 fixedly welded to the upper end of the base 1, a central screw 3 horizontally fixedly arranged on the column 2, a bidirectional screw 4 rotatably installed inside the column 2, a handle provided at the upper end of the bidirectional screw 4 for adjusting by rotating the bidirectional screw 4, two sets of first threaded sleeves 5 symmetrically sleeved on the bidirectional screw 4 by threads, two sets of sliders 6 slidably arranged inside the column 2, the two sets of first threaded sleeves 5 are respectively fixedly installed in the two sets of sliders 6, an upper limit rod 7 is rotatably installed on the upper slider 6, and a lower limit rod 8 is fixedly installed on the lower slider 6;

[0023] A sliding sleeve 11 is slidably sleeved on the central screw 3. Support rods 12 are symmetrically hinged at the upper and lower ends of the sliding sleeve 11. A second threaded sleeve 14 is threadedly sleeved on the side of the central screw 3 closest to the column 2. A connecting seat 16 is rotatably installed on the second threaded sleeve 14. Adjustment components connected to the support rods 12 are provided at both the upper and lower ends of the connecting seat 16. A limit sleeve 20 is threadedly sleeved on the side of the central screw 3 away from the column 2.

[0024] Furthermore, the upper limit rod 7 and the lower limit rod 8 have the same circular cross-section, and the central screw 3, the upper limit rod 7, and the lower limit rod 8 are arranged in parallel. For example... Figure 1 As shown, this structure allows the central screw 3 to be positioned at the center of the spring after the upper limit rod 7 and lower limit rod 8 are fitted onto the spring sleeve. This allows the upper limit rod 7 and lower limit rod 8, together with the two sets of support rods 12, to firmly support and limit the spring, thereby reducing swaying.

[0025] Furthermore, a stop rod 9 is provided at the end of the upper limit rod 7 furthest from the column 2, and the stop rod 9 is perpendicular to the upper limit rod 7. The end of the upper limit rod 7 closest to the column 2 passes through the slider 6 and is provided with a handle 10, which is perpendicular to the upper limit rod 7 and not parallel to the stop rod 9. Figure 1 and Figure 4 As shown, this structure allows the angle of the stop rod 9 to be adjusted by rotating the handle 10, so that the stop rod 9 can be raised to limit the end face of the spring, or opened downwards to facilitate the removal of the spring.

[0026] Furthermore, a through groove with a width matching the diameter of the upper limit rod 7 is provided in the middle of the support rod 12. The two sets of support rods 12 are respectively sleeved on the upper limit rod 7 and the lower limit rod 8 through the through groove. Baffles 13 are provided on both the front and rear surfaces of the upper support rod 12. Figure 1 and Figure 5 As shown, this structure is used to limit the end of the spring by means of the baffle 13, thereby increasing the limiting point. When the end of the spring abuts against the baffle 13, the device can better limit the spring. At the same time, the through groove of the support rod 12 facilitates the movement of the support rod 12 along the upper limit rod 7 and the lower limit rod 8 to avoid mutual interference. Meanwhile, the upper limit rod 7 and the lower limit rod 8 can restrict the rotation of the support rod 12.

[0027] Furthermore, a knob 15 is fixedly installed at one end of the second threaded sleeve 14 near the column 2. One side surface of the knob 15 is provided with anti-slip texture, and the other side surface of the knob 15 is octagonal. Figure 5 As shown, this structure allows for easy adjustment of the second threaded sleeve 14 by hand-tightening the knob 15, or by rotating the octagonal part with a wrench. At the same time, the outer end of the adjusting threaded sleeve 19 is hexagonal, and the right end of the limiting threaded sleeve 20 is also octagonal, which makes it convenient to adjust the position with a wrench.

[0028] Furthermore, the adjusting assembly includes a sleeve 17. The upper and lower ends of the connecting seat 16 are symmetrically hinged with sleeves 17. A support screw 18 is inserted into the opening of the sleeve 17. An adjusting sleeve 19 is rotatably installed at the opening of the sleeve 17. The adjusting sleeve 19 is threaded onto the support screw 18. The outer end of the support screw 18 is hinged to the lower side of the support rod 12. A guide groove is formed on the outer wall of the support screw 18, and a protrusion that matches the guide groove is formed on the inner wall of the sleeve 17. Figure 5 and Figure 6 As shown, this structure allows the rotation angle of the two sets of support rods 12 to be adjusted independently, making it easy for the two sets of support rods 12 to fit against the sides of the spring end face that are not flush, thus ensuring the effect of limiting and fixing. At the same time, the guide groove on the surface of the support screw 18 and the protrusion on the inner wall of the sleeve 17 prevent the support screw 18 from rotating within the sleeve 17. Therefore, the extension and retraction of the support screw 18 can only be adjusted by rotating the adjusting sleeve 19, thus ensuring the stability of the device.

[0029] Working principle: Before use, first turn the handle 10 downwards, so that the handle 10 drives the stop rod 9 downwards through the upper limit rod 7. Then, put the spring on the upper limit rod 7 and the lower limit rod 8 from the right side. Next, turn the knob 15 to make the second threaded sleeve 14 rotate and engage with the central screw 3, causing the connecting seat 16 to move to the left. Then, turn the limit threaded sleeve 20 to move to the left through the thread, so that the sliding sleeve 11 can move to the left along the central screw 3. When the distance between the two sets of support rods 12 and the stop rod 9 is equal to that of the spring... Once the lengths are matched, rotate the bidirectional screw 4, causing the two sets of first threaded sleeves 5 to move through the threaded action object, driving the two sets of sliders 6 to slide away from each other along the column 2, so that the upper limit rod 7 and lower limit rod 8 can respectively support the upper and lower inner walls of the spring. Then rotate the handle 10, causing the abutment rod 9 to stand upright and insert into the rear side of the position to be cut. Then rotate the knob 15, causing the second threaded sleeve 14 to drive the connecting seat 16 to move to the right, causing the two sets of support rods 12 to be opened and respectively abut against the upper and lower sides of the left end of the spring. Figure 2 and Figure 3As shown, the baffle 13 needs to be pressed against the left end of the spring. Since the spring is spiral, if the two sets of support rods 12 are tilted at the same angle, they may not be able to completely press against each other. Therefore, the two sets of adjustment components can be adjusted separately. Simply rotate the adjusting sleeve 19 so that the support screw 18 can extend and retract with the sleeve rod 17 through the thread action. This allows the tilt angle of the two sets of support rods 12 to be adjusted separately, so that the upper baffle 13 and the lower support rod 12 can both press against the upper and lower sides of the left end of the spring. This, together with the abutment rod 9, restricts the spring, which is convenient for subsequent cutting. After the cutting is completed, simply turn the handle 10 downwards to move the abutment rod 9 downwards. After the right end of the spring is no longer restricted, the spring can be removed. Then, put a spring of the same model on the upper limit rod 7 and the lower limit rod 8, and turn the handle 10 so that the abutment rod 9 presses against the right side of the spring to start the next cutting. The above is the complete working principle of this utility model.
