[0028] 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.

[0029] The utility model provides a spring feeding mechanism, such as Figure 1-Figure 3 As shown, the feeding mechanism includes a vibrating plate 3 mounted on one side of the grinding plate 2 on the base 1 and a material guide trough 31 fixedly arranged at the outlet end of the vibrating plate 3; the feeding mechanism also includes a concave frame 4 arranged on the side of the material guide trough 31 close to the grinding plate 2, a clamping block 41 symmetrically arranged on the concave frame 4 at a position corresponding to the outlet end of the material guide trough 31 for clamping a spring, an adjusting component 42 arranged on the concave frame 4 for adjusting the distance between the two clamping blocks 41, a mounting platform 5 fixedly arranged at a position below the material guide trough 31 on one side of the base 1, and a driving mechanism 6 arranged on the mounting platform 5 for driving the springs on the two clamping blocks 41 to move closer to or away from the through hole of the grinding plate 2.

[0030] When in use, pour the spring to be polished into the vibration plate 3, and start the vibration plate 3. Then, through the vibration and conveying action of the vibration plate 3, the vibration plate 3 can guide the spring to be polished inside it to the guide groove 31 in an orderly manner. When the spring is transported to the outlet end of the guide groove 31 in an orderly manner, the two clamping blocks 41 are adjusted to a suitable spacing under the adjustment action of the adjustment component 42 to clamp the spring to be polished at the outlet end of the guide groove 31. After the two clamping blocks 41 clamp the spring to be polished, the driving mechanism 6 is started. With the driving of the driving mechanism 6, the spring to be polished clamped by the two clamping blocks 41 can be smoothly moved and conveyed to the grinding plate 2. After the spring to be polished is aligned with the through hole on the grinding disc 2, the driving mechanism 6 will continue to push, and the spring to be polished will be automatically pushed into the aligned through hole. At the same time, the adjusting component 42 will adjust the distance between the two clamping blocks 41, and release the clamping of the two clamping blocks 41 on the spring to be polished, so that the spring to be polished can be smoothly and automatically transported to the through hole of the grinding disc 2. Afterwards, as the vibration disc 3, clamping blocks 41, adjusting component 42 and driving mechanism 6 repeat the above-mentioned vibration loading, clamping, moving and placing operations, the through holes on the grinding disc 2 can be completely filled with the springs to be polished or the springs to be polished in the vibration disc 3 can be automatically delivered.

[0031] Specifically, the adjustment assembly 42 includes a first servo electric cylinder 421 fixedly arranged on the concave frame 4 and fixedly connected to the side of the two clamping blocks 41 away from each other, and a first telescopic rod 422 arranged outside the first servo electric cylinder 421 and having two ends respectively fixedly connected to the side of the two clamping blocks 41 away from each other and the concave frame 4;

[0032] When the spring to be polished is guided and transported to the outlet end of the material guide trough 31, the two first servo electric cylinders 421 can stably push the two clamping blocks 41 to move closer or farther away under the telescopic guiding action of the corresponding first telescopic rods 422, so that the distance between the two clamping blocks 41 can be adjusted to ensure that they can clamp the spring to be polished transported to the outlet end of the material guide trough 31. When the spring to be polished supported by the clamping blocks 41 is driven by the driving mechanism 6 to move to the through hole of the grinding disc 2, at this time, driven by the two first servo electric cylinders 421, the two clamping blocks 41 will move away from each other, automatically releasing the clamping of the spring to be polished, so that the spring to be polished can be placed in the corresponding through hole.

[0033] Further, the driving mechanism 6 includes a connecting frame 61 arranged on the mounting platform 5 corresponding to the side of the concave frame 4 away from the grinding disc 2, a second servo electric cylinder 62 whose two ends are respectively fixedly connected to the connecting frame 61 and the concave frame 4, and a second telescopic rod 63 arranged outside the second servo electric cylinder 62 and whose two ends are respectively fixedly connected to the connecting frame 61 and the concave frame 4;

[0034] When the clamp block 41 is used to support the spring to be polished at the outlet end of the guide trough 31, the second servo electric cylinder 62 will start. At this time, under the telescopic guiding action of the second telescopic rod 63, the concave frame 4 connected to the second servo electric cylinder 62 will be driven by the second servo electric cylinder 62 to stably drive the clamp block 41 installed thereon to move closer to the grinding disc 2. When the clamp block 41 is close to the grinding disc 2 and the spring to be polished clamped by it is aligned with the through hole on the grinding disc 2, as the second servo electric cylinder 62 continues to drive, the spring to be polished clamped by the clamp block 41 can be stably pushed into the aligned through hole, and then the clamp block 41 can release the clamping of the spring to be polished at the same time, so that the spring to be polished can be placed in the corresponding through hole.

[0035] Among them, in order to protect the surface of the spring, rubber pads are fixedly installed on the sides of the two clamping blocks 41 that are close to each other; the design of the rubber pads can reduce the friction and scratches of the clamping blocks 41 on the surface of the spring when clamping the spring, thereby protecting the surface quality of the spring, and at the same time increasing the friction between the clamping blocks 41 and the spring to prevent the spring from sliding or falling off during the clamping process.

[0036] Example 2

[0037] Different from Example 1, in order to enhance the flexibility of the feeding mechanism, a rotating component 51 is provided on the mounting table 5, which is connected to the side of the connecting frame 61 away from the concave frame 4 and is used to rotate the springs on the two clamping blocks 41; after the springs are processed, the two clamping blocks 41 can be driven by the driving mechanism 6 to move to the through hole of the grinding disc 2, and the processed springs in the through hole can be clamped and detached from the through hole, and then rotated to one side of the mounting table 5 by the rotating component 51 for unloading, thereby reducing the production cost and eliminating the need for manual intervention.

[0038] Furthermore, the rotating assembly 51 includes a fixed seat 511 symmetrically fixedly mounted on the mounting platform 5 on a side away from the connecting frame 61, a worm 515 rotatably connected to the two fixed seats 511, a worm wheel 514 disposed on a side of the worm 515 close to the connecting frame 61 and meshing with the worm 515, a connecting shaft 513 rotatably connected to the mounting platform 5 and longitudinally penetrating the worm wheel 514, a bracket 512 fixedly disposed on the connecting shaft 513 at a position above the worm wheel 514 corresponding to the connecting frame 61 and fixedly connected to the connecting frame 61, and a motor 516 fixedly disposed on one of the fixed seats 511 for driving the worm 515 to rotate, and the worm wheel 514 is fixedly connected to the connecting shaft 513;

[0039] When the spring in the through hole on the grinding disc 2 is ground flat, the driving mechanism 6 can be started to push the clamping block 41 to move closer to the grinding disc 2. When the clamping block 41 is aligned with the spring in the through hole on the grinding disc 2, the adjusting assembly 42 is started to adjust the distance between the other clamping blocks 41 so that it can clamp the end of the spring. At the same time, the motor 516 is started and drives the worm 515 to rotate. Since the worm 515 is meshed with the worm wheel 514, and the connecting shaft 513 connected to the worm wheel 514 is fixedly connected to the bracket 512 connected to the connecting frame 61, When the motor 516 drives the worm 515 to rotate and move a certain number of circles, the connecting shaft 513 can drive the bracket 512 to rotate a certain angle toward the side of the mounting platform 5. At the same time, the spring clamped by the clamp block 41 can rotate to the side of the mounting platform 5 as the bracket 512 rotates. When the clamp block 41 is driven to rotate to the unloading position, the clamping of the spring by the clamp block 41 is released by adjusting the adjustment component 42, so that the spring can be automatically unloaded without manual intervention, and there is no need to set up other unloading structures.

[0040] 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.
