The structure of the specific clamping assembly 41 is as follows, each of the clamping assemblies 41 comprises a fixing rod 411, and there are three fixing rods 411 in total, wherein two fixing rods 411 are fixed at two sides of the bottom of a short side of the fixing frame 3, the other fixing rod 411 is fixed on the sliding support 423, and the fixing modes of the three fixing rods 411 are the same, and the fixing modes are realized by an upper clamping plate and a lower clamping plate which are parallel to each other up and down and a bolt, specifically, for the installation of the fixing rods 411 and the fixing frame 3, the distance between the upper clamping plate and the lower clamping plate is equal to the thickness of the fixing frame 3, and the upper clamping plate and the lower clamping plate are square plates, and after the fixing rods 411 sequentially pass through the lower clamping plate, the fixing frame 3 and the upper clamping plate from bottom to top, the fixing rods are locked by screwing the bolt; for the installation of the fixing rod 411 and the sliding support 423, the distance between the upper clamping plate and the lower clamping plate is equal to the thickness of the fixing frame 3, the upper clamping plate and the lower clamping plate are both circular plates, and the fixing rod 411 passes through the lower clamping plate, the sliding support 423 and the upper clamping plate from bottom to top in sequence and then is locked by screwing bolts; the setting of punch holder and lower plate can avoid dead lever 411 to produce and rock to guarantee clamping unit 41's clamping stability.

Specifically, the underground clamping rod 413 slides along the upper clamping rod 412 in a manner that a sliding groove 4121 extending in the radial direction is formed in the bottom of the upper clamping rod 412, specifically, the sliding groove 4121 extends outwards from the center of the upper clamping rod 412, a sliding rod 414 is arranged in the sliding groove 4121 in a sliding manner, specifically, the section of the sliding groove 4121 is "T" shaped, and the top of the sliding rod 414 is also "T" shaped; the lower clamping rod 413 is fixedly connected to the bottom of the sliding rod 414, the lower clamping rod 413 and the sliding rod 414 are coaxially arranged, and the switching between the unfolded state and the folded state of the upper clamping rod 412 and the lower clamping rod 413 is realized through sliding adjustment of the sliding rod 414 in the sliding groove 4121, specifically, when the sliding rod 414 slides until the central axis of the sliding rod 414 is coincident with the central axis of the upper clamping rod 412, the folded state of the upper clamping rod 412 and the lower clamping rod 413 is realized; when the sliding rod 414 slides to the state that the central axis of the sliding rod 414 is eccentric to the central axis of the upper clamping rod 412, the upper clamping rod 412 and the lower clamping rod 413 are in the unfolded state; when the workpiece 1 is pushed tightly at the first station, the sliding groove 4121 is parallel to the sliding direction of the sliding bracket 423, and one end of the sliding groove 4121, which is located at the center of the upper clamping rod 412, is close to the workpiece 1, so that the sliding rod 414 slides to the expanded state of the upper clamping rod 412 and the lower clamping rod 413; when the workpiece 1 is at the second station and is jacked tightly, the workpiece 1 is slowly rotated until the workpiece 1 drives the upper clamping rod 412 to rotate 180 degrees, at this time, the sliding rod 414 is parallel to the sliding direction of the sliding support 423, but one end of the sliding groove 4121, which is located at the center of the upper clamping rod 412, is far away from the workpiece 1, so that the sliding rod 414 slides until the upper clamping rod 412 and the lower clamping rod 413 are in a closed state, at this time, the sliding rod 414 abuts against one end of the center of the upper clamping rod 412 of the sliding groove 4121, the sliding rod 414 cannot continuously slide along the sliding groove 4121, so that the lower clamping rod 413 can also provide clamping force for the workpiece 1, the clamping effect on the workpiece 1 is further improved, and meanwhile, when the workpiece 1 is turned over and the workpiece 1 needs to be rotated for maintenance, clamping can be well achieved through the upper clamping rod 412.
It should be noted that, in the use process, the workpiece 1 is required to drive the upper clamping rod 412 or the lower clamping rod 413 to rotate, outer side walls of the upper clamping rod 412 and the lower clamping rod 413 are smooth, the friction force of the workpiece 1 to the workpiece 1 is small, and the workpiece 1 is not easy to drive the upper clamping rod 412 or the lower clamping rod 413 to rotate; when the fixed frame 3 moves to a position where the workpiece 1 is at the first station, that is, when the upper end surface of the workpiece 1 abuts against the bottom end surface of the upper clamping rod 412, the workpiece 1 can drive the clamping sleeve 415 to slide until the top end surface of the clamping sleeve 415 is flush with the bottom end surface of the upper clamping rod 412; before the fixed frame 3 moves to the second working position of the workpiece 1, the workpiece 1 can drive the clamping sleeve 415 to continuously slide along the upper clamping rod 412, that is, when the upper clamping rod 412 and the lower clamping rod 413 are in an unfolded state, the clamping sleeve 415 is only sleeved on the lower clamping rod 413, and before the upper clamping rod 412 and the lower clamping rod 413 are in a folded state, the clamping sleeve 415 is sleeved on the upper clamping rod 412.
In this embodiment, in order to ensure that the clamping sleeve 415 is kept attached to the lower clamping rod 413 and prevent the clamping sleeve 415 from falling off from the lower clamping rod 413, a plurality of spring plungers (not shown in the drawings) may be uniformly disposed on the outer side wall of the bottom end of the lower clamping rod 413, and a notch (not shown in the drawings) adapted to the spring plungers (not shown in the drawings) is formed on the inner side wall of the clamping sleeve 415, so that after the spring plungers (not shown in the drawings) abut against the notch (not shown in the drawings), the clamping sleeve 415 is locked with the lower clamping rod 413, and thus the clamping sleeve 415 cannot fall off from the lower clamping rod 413.
In order to realize the pushing of the workpiece 1 to the clamping sleeve 415, an annular limiting groove 4122 is further formed at the bottom of the upper clamping rod 412, a limiting ring 416 is fixedly connected to the top end surface of the clamping sleeve 415, the thickness of the limiting ring 416 is the same as that of the limiting groove 4122, and the limiting ring 416 protrudes out of the outer side wall of the upper clamping rod 412; the sliding groove 4121 is formed in the inner top wall of the limiting groove 4122; when the fixed frame 3 moves to a first station where the workpiece 1 is located, the workpiece 1 can push the limit ring 416 to be inserted into the limit groove 4122, and the clamping sleeve 415 is limited at the first station in a manner that the limit ring 416 is matched with the limit groove 4122; when the fixing frame 3 moves to the second working position of the workpiece 1, the workpiece 1 can push the limiting ring 416 to be separated from the limiting groove 4122 and continue to slide upwards, so that the clamping sleeve 415 is sleeved on the upper clamping rod 412.
In order to scrape impurities on the upper end face of the workpiece 1, an annular scraper 417 is arranged on the outer edge of the limiting ring 416, the arrangement of the scraper 417 increases the contact area between the workpiece 1 and the limiting ring 416, so that the limiting effect of the limiting ring 416 on the workpiece 1 is improved, and the clamping sleeve 415 can be sleeved into the upper clamping rod 412, wherein when the workpiece 1 is in the first station, the lower end face of the limiting ring 416 is attached to the upper end face of the lower clamping rod 413, namely the scraper 417 abuts against the upper end face of the workpiece 1, and when the workpiece 1 is pressed by the lower clamping rod 413, the scraper 417 can scrape the impurities on the upper end face of the workpiece 1 along the upper end face of the workpiece 1, and the workpiece 1 is rotated to completely scrape the impurities.
As a preferable structure of the scraper 417, the scraper 417 may be configured in a truncated cone shape, and the size of the upper end surface of the scraper 417 is larger than that of the lower end surface, so that the waste material scraped by the scraper 417 can be offset along the inclined surface of the scraper 417, and the situation that the scraped waste material obstructs the advance of the scraper 417 is avoided, and at the same time, the structure increases the working width of the scraper 417, thereby improving the working stability of the scraper 417.
