Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no order is shown between the two, and no indication or suggestion of relative importance is understood. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in fig. 1 to 3, the present embodiment discloses a grinding mechanism for a spring end surface, which includes a conveying unit 1, a receiving unit, and a grinding unit. Wherein the transport section 1 comprises a transport element for transporting the spring. The bearing part comprises a rotary table 2, a tray 3 which is positioned below the rotary table 2 and is used for being abutted against the lower end part of the spring, and a limiting part 4 which is annularly arranged on the outer side of the tray 3. The carousel 2 can be relative locating part 4 rotates, locating part 4 has installation breach 5, the outer fringe of carousel 2 is provided with the portion 6 of establishing that inlays that the opening is outside. The conveying piece is located at the installation gap 5 and is arranged corresponding to the embedding part 6, so that the spring can be transferred from the conveying part 1 into the embedding part 6, and the limiting part 4 is provided with an embedding groove capable of accommodating the spring partially embedded in the embedding part 6. The grinding part is used for grinding the spring embedded in the embedding part 6 and the embedding groove.

Through the arrangement mode, the springs can be automatically conveyed into the embedding part 6 from the conveying part 1, and the springs accommodated in the embedding part 6 and the embedding grooves are conveyed to the grinding part through the rotation of the rotary disc 2, so that the upper end part and the lower end part of the springs are ground. On one hand, the process of artificial filling is replaced, and the manual work in a dust environment is avoided; on the other hand, the grinding machine can continuously fill materials and continuously grind, and has high efficiency and compact structure.

In this embodiment, the conveying part 1 includes a conveying pipe 101 extending in the vertical direction, a first notch 102 located at the lower end of the conveying pipe 101, and a driving member. Referring to fig. 2 (note that, only one embedding portion 6 is shown in fig. 2, there are actually a plurality of embedding portions), specifically, the cross section of the conveying pipe 101 in the horizontal direction is a cylindrical shape adapted to the shape of the spring, and the inner diameter of the conveying pipe 101 is slightly larger than the outer diameter of the spring, so that the spring can slide to the bottommost portion in the conveying pipe 101 by gravity. The driving part comprises a driving cylinder or an automatic telescopic rod which can reciprocate in the horizontal direction, and preferably, the driving part comprises the driving cylinder in the mode. When the spring slides from the upper end of the conveying pipeline 101 to the first notch 102 of the lower end, the lower end of the spring abuts against the tray 3, and the driving cylinder pushes the spring from the first notch 102 to the embedding part 6 of the turntable 2 in the direction of the turntable 2. Preferably, the horizontal straight distance between the end of the first notch 102 and the end of the embedding part 6 is smaller than the diameter of the spring. The arrangement mode can ensure that the spring does not fall to the outside due to an overlarge gap between the spring and the first notch 102 when the spring is transferred into the embedding part 6 from the first notch.

In the present embodiment, the turntable 2 has a disk shape and is rotatable in the horizontal plane. The upper surface of the tray 3 may be polished, so that the friction between the lower end of the spring and the tray 3 is reduced during the rotation of the spring following the turntable 2, thereby allowing the spring to be better conveyed into the grinding part.

In the present embodiment, the cross section of the limiting member 4 on the horizontal plane is preferably arc-shaped. In this embodiment, the spring can be limited in the horizontal plane by a space that can be formed between the side wall of the limiting member 4 and the edge of the turntable 2. After the spring is accommodated in the embedding groove of the embedding part 6 and the limiting part 4 on the turntable 2, the upper end part of the spring is higher than the highest point of the turntable 2 and the limiting part 4, and the lower end part of the spring is lower than the lowest point of the turntable 2 and the limiting part 4.

In this embodiment, the cross section of the embedded portion 6 in the horizontal direction is arc-shaped, and the embedded portion can be adapted to the shape of the outer side wall of the spring, so that the shaking amount of the spring generated in the transmission process is reduced. The embedded portion 6 is provided in plurality around the circumference of the turntable 2 for abutting against the spring pushed out from the first notch 102.

In the present embodiment, the tray 3 is provided with an exit portion 9 through which the spring drops from the fitting portion 6 after passing through the polishing portion. The exit portion 9 is provided corresponding to each of the embedded portions 6, so that the spring drops from the embedded portion 6 to the exit portion 9 by gravity. Specifically, after the spring is ground by the grinding part, when the spring is moved to the outlet part 9, the spring can directly fall from the embedding part 6 and the embedding groove by gravity because the lower end part of the spring is not supported, and the spring passes through the outlet part 9 to realize finished product collection.

In this embodiment, the grinding portion includes an upper grinding disk 7 and a lower grinding disk 8 which are vertically disposed, and a grinding gap into which the spring is inserted is formed between the upper grinding disk and the lower grinding disk 8. The upper and

lower grinding disks

7, 8 each comprise a grinding wheel which can be brought into abutment with the end of the spring. Specifically, the inlet end and the outlet end of the grinding part are respectively butted with the tray 3, that is, the height of the lower grinding disk 8 in the vertical direction is consistent with that of the tray 3, so that the spring can be ensured to well enter and exit the grinding gap.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
