In order to achieve the above function, as shown in fig. 2, the conveying mechanism includes: a fixing part 8, a cam 9, a connecting part 10 and a chuck, wherein the chuck is coaxially connected with the conveying disc 5. One side surface of the fixing member 8 is fixed inside the vertical frame 1, and may be fixed by welding or may be fixedly connected by bolts. Cam 9, connecting piece 10 and chuck are equallyd divide rotatable the installation on mounting 8 respectively, and wherein, connecting piece 10 is the triangle-shaped, including first apex angle 11, second apex angle 12 and third apex angle 13, and first apex angle 11 and mounting 8 are articulated each other in order to realize the relation of being connected between connecting piece 10 and the mounting 8. And a roller is arranged at the second vertex angle 12, and the rolling surface of the roller is in contact with the rolling surface of the cam 9. A pawl 14 is hinged at the third top corner 13, and in order to be matched with the pawl 14, the chuck comprises: the body 15 and a plurality of clamping grooves 16 which are equidistantly arranged on the outer wall of the body 15. And in order to realize the pushing action of the pawl 14 on the chuck, the cam 9 comprises a wave section 901 and an arc surface 902 which is connected with two ends of the wave section 901 and protrudes outwards.

In a further embodiment, the undulating surface comprises: the first convex surface and the second convex surface respectively connected with two ends of the circular arc surface 902 in a transition manner further comprise a first concave surface connected with the first convex surface, a second concave surface connected with the second convex surface, and a third convex surface connected with the first concave surface and the second concave surface.

When the chuck is used, the axis of the cam 9 is in transmission connection with an output shaft of a driving motor, when the roller at the second vertex angle 12 is located on the arc surface 902 of the cam 9, the second vertex angle 12 is located at the topmost end, the arc surface 902 of the cam 9 has an upward ejection effect on the second vertex angle 12, so that the third vertex angle 13 and the ratchet 14 installed at the third vertex angle 13 are ejected to move towards the chuck and the ratchet 14 is located in one of the clamping grooves 16, and the chuck stops moving at the moment; the cam 9 continues to rotate, when the roller is located at the first convex surface, the second vertex angle 12 is slightly jacked, the third vertex angle 13 and the ratchet 14 at the third vertex angle 13 are slightly jacked, the ratchet 14 is slightly separated from the clamping groove 16, when the roller is located at the first concave surface, the ratchet 14 continuously moves downwards, the current clamping groove 16 is separated from the ratchet 14 and moves into the next clamping groove 16, when the roller is located at the second concave surface, the ratchet 14 is tightly clamped with the clamping groove 16, when the roller is located at the second convex surface, the second vertex angle 12 is jacked, the third vertex angle 13 and the ratchet 14 at the third vertex angle 13 are slightly jacked, the ratchet 14 pushes the clamping groove 16 at the current position upwards, and the chuck is pushed to repeat this operation.

In order to lock the chuck when the chuck stops rotating in the structure, a convex part 17 extending to the chuck by a preset height is arranged between the first vertex angle 11 and the third vertex angle 13; when the roller is located at the arc surface 902 (when the ratchet 14 is tightly clamped with the slot 16), the protruding part 17 is tightly clamped in the corresponding slot 16, so that a good locking effect is achieved.

In other words, based on the structure, intermittent rotation of the conveying disc 5 can be realized, and meanwhile, when the conveying disc 5 stops rotating, the lug boss 17 locks the chuck, so that when the grinding cutter 3 applies external force to the cylinder 7 to be ground, rotation of the conveying disc 5 cannot be caused, and grinding stability and precision are improved.

However, in the above embodiment, although the transportation tray 5 is fixed to ensure that the transportation tray 5 does not rotate under the action of the grinding blade 3, the to-be-ground cylinder 7 is placed inside the recess 6, that is, there is no other fixing action, and it cannot be ensured that the to-be-ground cylinder 7 itself located inside the recess 6 does not rotate. The space in the groove 6 is also quite compact, and how to fix the column 7 to be ground in the limited space becomes a difficulty.

In a further embodiment, in order to solve the above technical problem, the present embodiment discloses a clamping mechanism disposed in the groove 6. The clamping mechanism clamps and fixes the cylinder 7 to be polished. As shown in fig. 3, the chucking mechanism includes: the support 601 is fixed at the inner wall of the groove 6, and at least two sets of clamping pieces 602 are arranged at the edge of the support 601, and in the embodiment, the number of the clamping pieces 602 is three and is uniformly distributed. In order to control the working state of the clamping member 602, an electric cylinder is arranged below the bracket 601, and the electric cylinder is a small cylinder. The piston rod of the electric cylinder is connected with a pushing piece 603 in a transmission mode, the pushing piece 603 is connected with a connecting rod assembly in a transmission mode, the connecting rod assembly is connected to the clamping piece 602 in a transmission mode, when the electric cylinder pushes the piston rod out, the pushing piece 603 moves towards the support 601, and the connecting rod assembly pushes the clamping piece 602 to clamp.

To better illustrate the above structure, the clamping member 602 includes: the rotating shaft 6021 is rotatably arranged on the bracket 601, the two ends of the rotating shaft 6021 are fixedly provided with connecting blocks 6022, a connecting shaft 6023 is arranged between the two connecting blocks 6022, and the connecting shaft 6023 is in transmission connection with the connecting rod assembly. The top ends of the two connecting blocks 6022 are provided with holding blocks 6024 extending upward by a predetermined height. In other words, when the connecting shaft 6023 is pushed by the connecting rod assembly to move outwards, the clamping block 6024 rotates inwards around the rotating shaft 6021 as a circle center, and the column 7 to be ground is clamped and fixed.

In a further embodiment, a connecting rod assembly comprises: a first link 6025 hinged to the pushing member 603, and a second link 6026 hinged to the first link 6025, and the second link 6026 is simultaneously hinged to the connecting shaft 6023.

The working principle of the clamping mechanism is as follows: when the electric cylinder is in a compressed state, the pushing piece 603 is located at the lowest end, the included angle between the first connecting rod 6025 and the second connecting rod 6026 is the largest, the distance between the connecting shaft 6023 and the axis of the bracket 601 is the shortest, and the clamping block 6024 does not have a fixing effect on the grinding cylinder at the moment. When the cylinder 7 to be ground is placed in the groove 6, it is placed on the bracket 601. When the grinding cylinder needs to be fixed before grinding, a piston rod of the electric cylinder pushes out the pushing piece 603, the pushing piece 603 gradually moves upwards, in the process, an included angle between the first connecting rod 6025 and the second connecting rod 6026 is reduced, the connecting shaft 6023 is pushed outwards, and the clamping block 6024 rotates inwards by taking the rotating shaft 6021 as a circle center, so that the clamping and fixing effect on the to-be-ground cylinder 7 is achieved.

Based on the above description, treat the cylinder 7 of polishing through compact structure's fixture and fix, avoid polishing the cylinder when polishing and take place the rotation, increased the stability of the in-process of polishing and improved the precision of polishing.

In the above embodiment, the cylinder in the groove 6 is transferred to the polishing knife 3 through the conveying disc 5, and in order to facilitate conveying, a certain distance is reserved between the polishing knife 3 and the cylinder, so that the cylinder or the polishing knife 3 needs to be moved upwards or downwards to be capable of performing effective polishing treatment, and if the polishing knife 3 is moved downwards, the polishing knife 3 can be possibly simultaneously used for several times or contact with other cylinders 7 to be polished, so that effective control and conveying cannot be performed at the back, the phenomenon that the polishing degree between every two cylinders is inconsistent can occur, and the qualification rate is directly reduced.

In order to solve the above problems, the applicant has made a further improvement to the clamping mechanism: an ejector rod 604 is arranged at the axis position of the support 601, and the bottom of the ejector rod 604 is in transmission connection with a piston rod of the electric cylinder.

In other words, when the piston rod pushes the pushing piece 603, the ejecting rod 604 is ejected, the cylinder 7 to be polished is ejected by the ejecting rod 604, the height of the cylinder 7 to be polished is increased, the cylinder 7 to be polished is contacted with the polishing knife 3 to be polished conveniently, the height of the cylinder to be polished and the other cylinders 7 to be polished is lower than the height of the cylinder being polished, targeted and one-to-one polishing is realized, and the qualification rate of products is increased.

The clamping groove 16 plays a role in guiding and supporting the sliding cover 1805, and when the sliding cover 1805 is in a closed state, more columns 7 to be polished can be supported.

However, in the above embodiment, when the sliding cover 1805 is directly used to control the feeding rhythm of the feeding mechanism 18, when the sliding cover 1805 obstructs the current sliding cover 1805 and the next sliding cover 1805, the following phenomenon will occur, if the current sliding cover 1805 is closed in advance, the current sliding cover 1805 is blocked, if the next sliding cover 1805 is closed in a delayed manner, the next sliding cover 1805 is blocked or falls in advance, the feeding rhythm cannot be controlled, and the column 7 to be polished falling into the groove 6 is placed in an inclined manner, so that a serious processing accident exists during polishing.

Therefore, the above problem is solved by providing the guide groove 1806 as a buffer section, the feeding mechanism 18 is disposed at one side of the transfer tray 5, and the guide groove 1806 is disposed between the feeding mechanism 18 and the transfer tray 5, and the guide groove 1806 is obliquely disposed between the transfer tray 5 and the through hole 1802.
