[0028] In order to make the personnel in the technical field better understand the utility model scheme, below will combine the drawing in the utility model embodiment, and the technical scheme in the utility model embodiment is clearly and completely described.

[0029] Example 1:

[0030] Reference Attachment Figure 1 , Attachment Figure 2 , and attached Figure 3 A spring grinding machine capable of processing a variety of springs includes a base 10, a loader 11 fixedly mounted on one side of the upper end surface of the base 10, and a plurality of feeding tubes 35 mounted on the loader 11. A rotating base 13 is fixedly mounted below the loader 11 on the upper end surface of the base 10, and a feeding port 12 is fixedly mounted below the plurality of feeding tubes 35 on the upper end surface of the rotating base 13. Production personnel can vertically feed the material to be processed from the loading tubes 35 into the rotating base 13; the rotating base 13 can also be connected to a feeding vibration plate, so that the material to be processed can be automatically fed in the desired vertical position. The specific feeding vibration plate is prior art and is not described in this solution or embodiment.

[0031] For further information, see the attached Figure 3 , Attachment Figure 4 And attached Figure 8 A first drive motor 14 is fixedly mounted on the upper end surface of the rotating base 13. The output end of the first drive motor 14 is connected to a first rotating shaft 15 within the rotating base 13. Multiple fixing components are connected to the outer circumference of the first rotating shaft 15 below the loading port 12. The first drive motor 14 drives the first rotating shaft 15 within the rotating base 13 to rotate. When one of the fixing components connected to the first rotating shaft 15 rotates below the loading port 12, the spring to be processed is dropped from the loading port 12 into the rotating base 13, where it is secured by the fixing component and can be rotated together with the first rotating shaft 15.

[0032] For further information, see the attached Figure 4 With attached Figure 9 The fixing assembly includes a fixing frame 16 fixedly set on the first rotating shaft 15, an electric push rod 17 is fixedly set on the side of the fixing frame 16 close to the first rotating shaft 15, and a sliding plate 18 is slidingly set on the side of the fixing frame 16 away from the first rotating shaft 15. The sliding plate 18 is connected to the output end of the electric push rod 17, and a plurality of openings 19 that cooperate with the feeding tube 35 are provided on the sliding plate 18. Four rotating rods 20 connecting the fixing frame 16 and the sliding plate 18 are symmetrically provided outside the openings 19 on the upper and lower sides of the sliding plate 18. The rotating rod 20 is in a bent shape, and a clamping claw 36 is connected to the end surface of the rotating rod away from the rotating connection point.

[0033] By controlling the output end of the electric push rod 17, the production personnel can control the sliding plate 18 to slide in the fixed frame 16. When the sliding plate 18 slides, the multiple rotating rods 20 connecting the sliding plate 18 and the fixed frame 16 will change the angle and drive the clamping claws 36 thereon to clamp or loosen, ultimately achieving the effect of loosening or tightening the multiple rotating rods 20 at the same time.

[0034] Further, referring to the accompanying drawings Figure 8 , considering that the working end of the rotating rod 20 clamping and fixing the spring is fixed in shape and cannot well adapt to the outer cylindrical surface of springs of different sizes, in order to improve the clamping and fixing effect of the fixing assembly, the elastic layer 21 is fixedly arranged on each clamping jaw 36.

[0035] Further, referring to the accompanying drawings Figure 4 , the accompanying drawings Figure 5 , the accompanying drawings Figure 6 and the accompanying drawings Figure 8 , the rotating seat 13 is provided with an opening 22 on one side, and a first support beam 24 is fixedly arranged on the upper end face of the base 10 away from the outer side of the rotating seat 13. The upper end face of the first support beam 24 is fixedly provided with a second driving motor 25, and the output end of the second driving motor 25 is connected and arranged below the first support beam 24. A second rotating shaft 26 is arranged on the second driving motor 25 in a vertical direction, and a grinding assembly is slidingly arranged on the second rotating shaft 26. The grinding assembly is in close contact with the opening 22.

[0036] Further, referring to the accompanying drawings Figure 6 and the accompanying drawings Figure 8 , the grinding assembly includes two sliding support plates 29 slidingly arranged below the first support beam 24. Adjacent end faces of the two sliding support plates 29 are rotatably provided with grinding wheels 27. An end face bearing 28 is connected and arranged between the grinding wheel 27 and the sliding support plate 29. Each 27 and 26 are connected by a key transmission. The specific transmission key position is known in the art, and this scheme will not be described in detail.

[0037] The second driving motor 25 can drive the second rotating shaft 26 and the two grinding wheels 27 to rotate. When the first driving motor 14 drives the first rotating shaft 15 to rotate and drives the fixing assembly and the plurality of springs to be machined to rotate to the opening 22, the upper and lower grinding wheels 27 can perform grinding spring operation on the spring to be machined. The end face bearing 28 connected and arranged between the grinding wheel 27 and the sliding support plate 29 can prevent the grinding wheel 27 from being stuck during rotation.

[0038] Further, referring to the accompanying drawings Figure 7The second support beam 30 is fixedly arranged on the upper end face of the base 10 away from the feeder 11, the third driving motor 31 is fixedly arranged on the upper end face of the second support beam 30, the double screw rod 32 is connected and arranged below the second support beam 30, the two screw threads with opposite rotation directions are symmetrically arranged on the double screw rod 32, and the two sliding support plates 29 in the two grinding assemblies are connected with the double screw rod 32. Considering that the rotating grinding wheel 27 needs to be gradually fed for grinding during the spring machining process, and the fixed assembly is fixedly arranged with a plurality of to-be-machined springs in a relaxed state, different grinding amounts may be required for grinding different spring materials, and the positions and feeding amounts of the two grinding wheels 27 need to be adjusted; the third driving motor 31 can drive the double screw rod 32 to rotate and make the two sliding support plates 29 connected and driven synchronously or away from each other, and the end face bearing 28 is arranged to enable the grinding wheel 27 to normally rotate with the second rotating shaft 26 during the sliding process of the sliding support plate 29.

[0039] Further, reference 4, attached Figure 8 and attached Figure 9 The fixed assembly is arranged with a discharge port 33 on one side of the rotating seat 13 and the base 10, and the discharge port 33 is slidably arranged with a material collecting cabin 34 below the lower end face of the base 10. When the processed material is transferred to the upper side of the discharge port 33, it can fall into the material collecting cabin 34 through the discharge port 33, and the production personnel can pull out the material collecting cabin 34 to take it away. Specifically, the material collecting cabin 34 can be a pull-out structure, which is prior art, and the present scheme does not make too many limitations.

[0040] Specifically, initially, the spring passes through the feeding port 12 into the rotating seat 13 through the feeder 11, and the spring falls into the hole 19 in the fixed assembly below the feeder 11. At this time, the spring is not fixedly clamped, the output end of the electric push rod 17 in the fixed frame 16 is connected with the sliding plate 18, the output end of the electric push rod 17 can drive the sliding plate 18 to retract and drive the plurality of rotating rods 20 on the upper and lower surfaces of the sliding plate 18 to rotate, so that the plurality of clamping jaws 36 are tightened inwardly, thereby clamping the to-be-machined spring in the plurality of holes 19. The clamping jaw 36 at the end of the rotating rod 20 is fixedly arranged with an elastic layer 21, which can better adapt to different sizes of materials.

[0041] After the clamping is completed, the first driving motor 14 drives the first rotating shaft 15 to rotate, which can drive the fixed assembly and the plurality of springs thereon to rotate to one side of the opening 22. At this time, the fixed assembly and the springs thereon are located between the two grinding wheels 27. Then, the second driving motor 25 can drive the second rotating shaft 26 and the two grinding wheels 27 to rotate. The third driving motor 31 can drive the double helical screw rod 32 to rotate, so that the two sliding support plates 29 symmetrically driven thereon move close to each other, so that the two grinding wheels 27 move close to and compress the spring material, and then the spring material is subjected to spring grinding treatment.

[0042] After the spring grinding treatment is completed, the third driving motor 31 drives the double helical screw rod 32 to reverse, so that the two sliding support plates 29 driven thereon drive the two grinding wheels 27 to move away from the processed spring material. The second driving motor 25 stops driving the grinding wheels 27 to rotate. The first driving motor 14 drives the first rotating shaft 15 to rotate, which drives the plurality of processed spring materials to move away from the opening 22. At the same time, the next group of materials is also transferred to the opening 22 to wait for the next group of spring grinding treatment. The spring material of the previous group of spring grinding is transferred to the upper side of the discharge port 33. The output end of the electric push rod 17 is extended and drives the sliding plate 18 to slide. The rotating rods 20 connected between the sliding plate 18 and the opening 19 are rotated, so that the corresponding plurality of clamping jaws 36 loosen the spring material clamped thereon. The processed spring material falls into the material collecting cabin 34 through the discharge port 33.

[0043] Embodiment two:

[0044] Reference to the accompanying Figure 1 With the accompanying Figure 8 On the upper end surface of the base 10 on both sides of the opening 22, two symmetrical dust collectors 23 are also fixedly arranged. The output ends of the two dust collectors 23 extend to both sides of the grinding wheel working position of the device through the opening 22. Considering that a large amount of metal powder will be generated during the grinding process of the device on the spring material, the metal powder scattered in the device will be not conducive to the later maintenance and maintenance of the device, and the metal powder will also cause health problems if inhaled by the production personnel. The dust collector 23 can timely suck away the metal powder generated during the spring grinding process of the device to prevent the above problems.
