Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a spring end grinding tool. Background Art

[0002] In the manufacturing and processing of compression springs, the processing of spring ends is a crucial link. Among them, the flatness of the spring ends directly affects the performance of the spring, including its elasticity, durability, and the accuracy of matching with other components. Especially in high-end manufacturing industries such as precision instruments, automotive parts, aerospace, etc., the flatness of the spring ends is extremely high, and any tiny flaws may affect the performance and reliability of the entire system.

[0003] The Chinese utility model patent with publication number CN218613200U discloses a spring end grinding device. In the patent, a movable grinding wheel is provided so that a larger portion of the bottom end of the grinding wheel can be in contact with the upper surface of the spring during grinding. In the production process of springs, due to differences in manufacturing processes and raw materials, even springs of the same diameter may have certain differences in length. However, in the existing spring end grinding device, the loading mechanism for placing the spring adopts a single fixed structure. This design greatly limits the adaptability and flexibility of the device. Under this fixed structure, the loading mechanism can only accommodate springs of a specific length. Once springs of different lengths need to be ground, an end grinding device of the corresponding size must be replaced or equipped.

[0004] Therefore, a spring end grinding tool with strong adaptability is needed to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The utility model provides a spring end grinding tool, aiming to solve the problem that the existing material loading mechanism for placing the spring proposed in the background technology adopts a single fixed structure, and this design greatly limits the adaptability and flexibility of the device.

[0009] In order to improve the adaptability of the end grinding tool, unlike the existing end grinding tool, the loading mechanism includes a fixed box rotatably mounted on the inner side of one end of the two fixed frames away from the base, a grinding disc arranged on the side where the two fixed boxes are close to each other, through holes distributed in a circular array on the grinding discs, an adjusting mechanism arranged on the fixed box for driving the two grinding discs to move closer or farther away, and a rotating motor fixed on one of the fixed frames for driving the fixed box to rotate, and the corresponding through holes on the two grinding discs are coaxially arranged; the combined design of the adjusting mechanism driving the two grinding discs to move closer or farther allows the operator to easily adjust the distance between the two grinding discs as needed to adapt to springs of different lengths, thereby improving the versatility and adaptability of the end grinding tool.

[0010] Preferably, in order to improve protection, a transparent protective cover for covering the loading mechanism and the grinding mechanism is fixedly installed on the base at the upper position corresponding to the two fixed frames; the transparent protective cover can effectively grind away the debris during the operation and prevent it from splashing around, thereby improving the safety of the operation.

[0011] Preferably, in order to facilitate the adjustment of the spacing between the two grinding discs, the adjustment mechanism includes a bidirectional screw rotatably connected to the two fixed boxes and threadedly connected to the two grinding discs, a guide rod arranged on the outside of the bidirectional screw and fixedly connected to the two fixed boxes, and a servo motor fixedly arranged in one of the fixed boxes for driving the bidirectional screw to rotate, and the two grinding discs are slidably connected to the guide rod; the combined design of the bidirectional screw, the guide rod and the servo motor makes it possible for the operator to easily adjust the spacing between the two grinding discs without having to adjust each grinding disc individually, and only needs to control the servo motor to rotate the bidirectional screw.

[0012] Preferably, in order to improve the efficiency of grinding, the grinding mechanism includes a mounting plate arranged on the inner side of one end of the two fixed frames close to the base, a grinding wheel rotatably arranged on the side of the mounting plate away from the fixed frame and located on the outside of the grinding disc, and a driving motor fixedly arranged on the side of the mounting plate close to the grinding wheel for driving the grinding wheel to rotate; through two symmetrically arranged grinding wheels, both ends of the springs placed in the corresponding through holes of the two grinding discs can be ground at the same time. This synchronous operation greatly reduces the time required for grinding and significantly improves work efficiency.

[0013] Preferably, in order to further improve the adaptability of the end grinding tool, the grinding mechanism also includes a servo electric cylinder fixedly arranged on the fixed frame and fixedly connected to the mounting plate for driving the grinding wheel to move closer to or away from the grinding disc, and a telescopic rod fixedly arranged on the outside of the servo electric cylinder and fixedly connected to the mounting plate and the fixed frame at both ends; through the adjustment of the servo electric cylinder, the two grinding wheels can automatically adapt to springs of different lengths, thereby further improving the flexibility of the use of the end grinding tool.

[0014] Preferably, in order to protect the spring, a rubber pad is fixedly provided in the through hole; the design of the rubber pad can prevent the spring from directly contacting the inner wall of the through hole, thereby preventing the surface of the spring from being scratched or worn during the placement or removal process.

This synchronous operation greatly reduces the time required for grinding and significantly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a spring end grinding tool, such as Figure 1-Figure 3 As shown, the end grinding tool includes a base 1, a fixing frame 2 symmetrically fixedly mounted on the base 1, a loading mechanism 3 arranged between the two fixing frames 2 for placing springs, and a grinding mechanism 4 arranged between the two fixing frames 2 for grinding the springs on the loading mechanism 3; the loading mechanism 3 includes a fixing box 31 rotatably mounted on the inner side of one end of the two fixing frames 2 away from the base 1, a grinding disc 32 arranged on the side where the two fixing boxes 31 are close to each other, through holes 33 distributed in a ring array on the grinding disc 32, an adjusting mechanism 34 arranged on the fixing box 31 for driving the two grinding discs 32 to move closer or farther, and a rotating motor 35 fixedly arranged on one of the fixing frames 2 for driving the fixing box 31 to rotate, and the corresponding through holes 33 on the two grinding discs 32 are coaxially arranged.

[0028] When in use, first start the adjustment mechanism 34 according to the length of the spring to be ground, adjust the distance between the two grinding discs 32, and after the adjustment is completed, pause the operation of the adjustment mechanism 34, and then start the rotating motor 35 to drive the fixed box 31 to which it is fixed to rotate. Since the two fixed boxes 31 are connected to the two grinding discs 32 through the adjustment mechanism 34, the spring to be ground can be placed in turn in the corresponding connected through holes 33 set on the two rotating grinding discs 32, and start the grinding mechanism 4 at the same time. As the two grinding discs 32 rotate, the springs placed in the corresponding connected through holes 33 can be ground in turn through the grinding mechanism 4.

[0029] Specifically, the adjustment mechanism 34 includes a bidirectional screw 341 rotatably connected to the two fixing boxes 31 and screwed to the two grinding discs 32, a guide rod 342 disposed outside the bidirectional screw 341 and fixedly connected to the two fixing boxes 31, and a servo motor 343 fixedly disposed in one of the fixing boxes 31 for driving the bidirectional screw 341 to rotate, and the two grinding discs 32 are slidably connected to the guide rod 342;

[0030] Before performing the grinding operation, the operator can first start the servo motor 343 according to the length of the spring to be ground, and drive the bidirectional screw 341 to rotate. Since the bidirectional screw 341 is threadedly connected to the two grinding discs 32, and the two grinding discs 32 are slidably connected to the guide rod 342, the two grinding discs 32 can move closer or farther synchronously with the rotation of the bidirectional screw 341. Therefore, the distance between the two grinding discs 32 can be adjusted by simply controlling the number of turns of the bidirectional screw 341 driven by the servo motor 343. After that, the operator only needs to put the spring to be ground into the corresponding connecting through hole 33 of the two grinding discs 32, and then use the grinding mechanism 4 to grind it.

[0031] Furthermore, the grinding mechanism 4 includes a mounting plate 41 disposed on the inner side of one end of the two fixing frames 2 close to the base 1, a grinding wheel 42 rotatably disposed on the side of the mounting plate 41 away from the fixing frame 2 and located outside the grinding disc 32, and a driving motor 43 fixedly disposed on the side of the mounting plate 41 close to the grinding wheel 42 for driving the grinding wheel 42 to rotate;

[0032] After adjusting the distance between the two grinding discs 32 to accommodate the placement of springs of different lengths to be polished, the rotating motor 35 and the two driving motors 43 can be started synchronously. At this time, the rotating motor 35 will drive the springs to be polished placed on the two grinding discs 32 to rotate to the two grinding wheels 42 in sequence. When each spring to be polished rotates between the two grinding wheels 42, the two driving motors 43 will synchronously drive the two grinding wheels 42 to rotate, and synchronously grind the two ends of each spring to be polished.

[0033] Furthermore, the grinding mechanism 4 also includes a servo electric cylinder 44 fixedly arranged on the fixing frame 2 and fixedly connected to the mounting plate 41 for driving the grinding wheel 42 to move closer to or away from the grinding disc 32, and a telescopic rod 45 fixedly arranged on the outside of the servo electric cylinder 44 and having two ends fixedly connected to the mounting plate 41 and the fixing frame 2 respectively;

[0034] After adjusting the distance between the two grinding discs 32 according to the length of the spring to be polished, the two servo electric cylinders 44 can be started synchronously to drive the two mounting plates 41 to move closer or farther away. At this time, the two mounting plates 41 can be guided by the telescopic rods 45 arranged thereon to synchronously and stably drive the two grinding wheels 42 to move closer or farther away, so that the grinding positions of the two grinding wheels 42 can be synchronously adjusted according to the length of the spring to be polished.

[0035] In order to protect the spring, a rubber pad is fixedly provided in the through hole 33; the design of the rubber pad can prevent the spring from directly contacting the inner wall of the through hole 33, thereby preventing the surface of the spring from being scratched or worn during the placement or removal process.

[0036] In addition, in order to improve protection, a transparent protective cover 11 for covering the loading mechanism 3 and the grinding mechanism 4 is fixedly installed on the base 1 at the upper position corresponding to the two fixed frames 2; the transparent protective cover 11 can effectively grind away the debris during the operation and prevent it from splashing around, thereby improving the safety of the operation.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
