Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically a high-temperature resistant spring grinding and chamfering device. Background Technology

[0002] As an elastic element widely used in mechanical systems, springs usually require chamfering at their ends to eliminate sharp edges, reduce stress concentration, improve fatigue life, and facilitate installation. Traditional spring chamfering methods mainly include manual chamfering and mechanical chamfering. Manual chamfering is inefficient and inconsistent, making it difficult to meet the needs of mass production. While existing mechanical chamfering equipment is more efficient, it is usually complex in structure and expensive. Traditional spring grinding equipment often can only grind one end of the spring or requires manually flipping the spring to grind the other end, resulting in low efficiency.

[0003] With the development of technology, some equipment has appeared on the market that can grind both ends of a spring at the same time. However, although these devices have made progress in grinding both ends, they still have some limitations and shortcomings. Grinding equipment on the market is often designed for springs of specific specifications. For springs of different sizes and lengths, it is necessary to change the fixtures or equipment, which increases the complexity and cost of operation. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] Example

[0029] Please see Figure 1-6 In this embodiment of the present invention, a high-temperature resistant spring grinding and chamfering device includes a clamping mechanism 100, an adjusting mechanism 200, a grinding mechanism 300, and a supporting mechanism 400. The clamping mechanism 100 includes a first disk 110 and a second disk 120, which are of the same size. The second disk 120 is located above the first disk 110. The top surfaces of the first disk 110 and the second disk 120 are provided with a plurality of placement slots 130 at equal angles. The placement slots 130 on the first disk 110 and the second disk 120 correspond to each other. The top surfaces of the first disk 110 and the second disk 120 are both provided with polygonal slots that penetrate through them. Each placement slot 130 is equipped with a fixed clamping plate 140 and a movable clamping plate 150. The fixed clamping plate 140 and the movable clamping plate 150 are symmetrical to each other and have a certain curvature to clamp the spring. A strip rod 151 is fixedly connected to the outer wall of each of the movable clamping plates 150. The fixed clamping plate 140 is fixedly connected to the inner wall of the placement slot 130, and the strip rod 151 is slidably connected to the placement slot 130. The ends of the movable clamping plates 150 are provided with insertion slots. The adjustment mechanism 200 includes a polygonal column 210. The top surface of the polygonal column 210 is provided with a through mounting slot 211. The first disc 110 and the second disc 120 are both connected to the polygonal column 210. The outer wall of the 0 is fitted with a circular disc 110 fixed to the outer wall of the polygonal column 210. Several electric telescopic rods 220 are fixedly connected at equal angles to the outer wall of the polygonal column 210. The positions of the electric telescopic rods 220 correspond to the positions of several placement slots 130. A rectangular rod 230 is fixedly connected to the output end of each electric telescopic rod 220. The rectangular rod 230 is slidably inserted into the insertion slot on the strip rod 151. The grinding mechanism 300 includes a rotating column 310 rotatably connected to the mounting slot 211. A drive motor 320 is provided at the bottom end of the rotating column 310. The motor shaft of the drive motor 320 is connected to the bottom of the rotating column 310. The end drive connection can drive the rotating column 310 to rotate. The top and bottom of the rotating column 310 are respectively equipped with a motor-driven grinding wheel 350 and a grinding wheel 370. The positions of the grinding wheel 350 and the grinding wheel 370 correspond to the positions of the placement groove 130. The support mechanism 400 is fixedly connected to the disc 110 and can restrict the position of the disc 110. The support mechanism 400 includes four electric telescopic rods 430. The output ends of the four electric telescopic rods 430 are fixedly connected to the outer wall of the disc 120. Controlling the extension or retraction of the electric telescopic rods 430 can drive the disc 120 to move up and down.

[0030] Specifically, several springs are sequentially placed into several placement slots 130, and several electric telescopic rods 220 are controlled to extend and push rectangular rods 230, causing the rectangular rods 230 to move the movable clamping plate 150 closer to the fixed clamping plate 140 until the springs are firmly clamped by the fixed clamping plate 140 and the movable clamping plate 150. Then, grinding wheels 350 and 370 are started to rotate and grind the two ends of the springs in the placement slots 130 until the two ends of the springs are ground flat. The drive motor 320 is then activated. The motor shaft drives the rotating column 310 to rotate, causing the first grinding wheel 350 and the second grinding wheel 370 to rotate around the rotating column 310 as the axis. This allows several springs to be ground in sequence. When a spring that needs to be processed is long, the four electric telescopic rods 430 are extended, causing the second disc 120 to move upward along the outer wall of the polygonal column 210. This changes the distance between the first disc 110 and the second disc 120, making the clamping force on the spring surface relatively uniform and ensuring grinding accuracy.

[0031] like Figure 2 As shown, in this embodiment, the support mechanism 400 includes four support legs 410 arranged at equal angles. The top ends of the four support legs 410 are fixedly connected to the outer wall of the disc 110. Each pair of support legs 410 is fixedly connected to each other by a connecting plate 420. The bottom ends of the four electric telescopic rods 430 are fixedly connected to the top surfaces of the four connecting plates 420 respectively.

[0032] In this embodiment, the connecting plate 420 can be installed and fixed in the operating area to support the device, so that when the second disc 120 is pushed upward by the third electric telescopic rod 430, the position of the first disc 110 remains unchanged, thereby improving stability.

[0033] like Figure 3-4 As shown, in this embodiment, the inner sidewalls of several placement slots 130 are symmetrically provided with two sliding grooves 131, the two outer sidewalls of several strip rods 151 are fixedly connected with sliders 152 that are slidably connected to the sliding grooves 131, and the inner sidewalls of several fixed clamping plates 140 and movable clamping plates 150 are provided with anti-slip pads for contacting the spring surface.

[0034] In practice, due to the sliding connection between the slider 152 and the slide groove 131, the position of the movable clamping plate 150 can always correspond to and be flush with the fixed clamping plate 140. When the disc 120 moves up and down, the bar rod 151 will also move up and down along the outer wall of the rectangular rod 230 with the disc 120, which enhances the stability of the adjustment of the disc 120.

[0035] like Figure 6As shown, in this embodiment, a top plate 330 is fixedly connected to the top of the grinding mechanism 300, and an electric telescopic rod 340 is fixedly connected to the bottom surface of the top plate 330. The output end of the electric telescopic rod 340 is fixedly connected to the motor of the grinding wheel 350. A bottom plate 360 ​​is fixedly connected to the bottom end of the rotating column 310, and the end side of the bottom plate 360 ​​is fixedly connected to the motor of the grinding wheel 370. Two square sleeves 390 are symmetrically fixedly connected to the bottom surface of the top plate 330, and square rods 3 are slidably inserted into the bottom of each of the two square sleeves 390. 91. The bottom ends of the two square rods 391 are fixedly connected to the fixed sleeves 392 that are fixed to the output end of the electric telescopic rod 340. The output end of the electric telescopic rod 340 can be fixed so that it can rotate without being affected by external forces. The grinding mechanism 300 also includes an annular plate 380, which is flush with the grinding wheel 370 and located below the disc 110. It can lift the unclamped spring. The bottom surface of the annular plate 380 is fixedly connected to the side wall of the base plate 360 ​​through two connecting rods 381.

[0036] In practice, the bottom of the disc 110 forms a stable support surface through the grinding wheel 370 and the annular plate 380, which can prevent the spring from slipping when it is placed in the placement groove 130 but not clamped. When the rotating column 310 drives the grinding wheel 370 to rotate, the annular plate 380 fixed on the outer wall of the base plate 360 ​​rotates synchronously. The electric telescopic rod 340 can drive the grinding wheel 350 to move up and down, which can accommodate springs of different lengths.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
