Therefore, when polishing cylindrical products, two different polishing devices need to be used, which makes the work efficiency low. After polishing, traditional stainless steel products need to be manually disassembled from the polished workpiece and the fixture, which is time-consuming and labor-intensive, and cannot effectively ensure the continuity of the polishing equipment. After searching, Chinese patent publication number CN202011500793.5 discloses a polishing device and polishing method for stainless steel products; including a side plate, a lateral position adjustment unit, a rotating unit, a polishing diameter adjustment unit, a polishing unit, and a fixed unit; a fixed unit is installed at the middle position of the side of the side plate, a rotating unit is installed on the rear side of the side plate through the lateral position adjustment unit, a polishing diameter adjustment unit is installed on the side of the rotating unit close to the fixed unit, and a polishing unit is installed on the sliding block of the polishing diameter adjustment unit; the polishing unit includes a support 1, a support shaft 1, a rotating rod 1, a support rod, a support shaft 2, a support 2, a fixed column, a movable sleeve, a pin shaft, a rotating rod 2, a connecting shaft, a polishing rod, a sliding rod, a sliding sleeve, a sliding disc, a spring, an end cover and a threaded sleeve; The structure in the above patent effectively clamps and fixes the product through two arc-top fixing plates when polishing the product, drives the polishing unit to rotate through the rotating unit to achieve polishing of the inside of the stainless steel product, and adjusts the distance between the two polishing rods in the polishing unit to achieve effective polishing of products of different sizes. Then, the polishing rod is adjusted to the outer surface of the stainless steel product, and the polishing unit is driven to rotate through the rotating unit to achieve surface polishing of the stainless steel product. In this way, when polishing, it is necessary to polish the other side after polishing one side, which will result in a long adjustment time. When polishing the outer side, the position clamped by the two arc-shaped fixing plates cannot be effectively polished, and the product needs to be clamped and fixed again, affecting work efficiency.

At this time, the short end of the pressing plate is moved backward under the action of the rotating shaft and the torsion spring.

The present invention; after polishing is completed, the electric push cylinder drives the installation box to move upward, and at the same time, the matching frame drives the triangular support to separate from the roller, and the sliding rod at the end of the slide plate passes through the second L-shaped plate. Under the action of the spring sleeved between the end of the sliding rod and the second L-shaped plate, the first polishing wheel is driven to move backward to separate the first polishing wheel from the workpiece.

[0024] The working principle of the present invention is as follows: when in use, the tilting frame 40 is fixedly installed on the workbench 3 through the pillars 43. The two groups of pillars 43 at the bottom of the tilting frame 40 have different lengths, which effectively ensures the tilting angle of the tilting frame 40. The workpiece 7 is placed in the guide groove 41 provided on the tilting frame 40 through the mechanical clamp, and the workpiece 7 is rotated by itself to achieve rolling from high to low. During the rolling process of the workpiece 7, the workpiece 7 presses the pressing plate 48 downward, and the workpiece 7 smoothly passes through the guide groove 41 and enters the first rectangular groove 42, and is effectively supported by the support crossbar 44 installed in the first rectangular groove 42. The next workpiece 7 is placed, and the workpiece 7 presses the pressing plate 48 by rolling. At this time, the short end of the pressing plate 48 moves backward under the action of the rotating shaft and the torsion spring. When moving backward, the fixed rod at the bottom of the pressing plate 48 pulls the first connecting rod 47, and the end of the first connecting rod 47 away from the fixed rod is connected with the L-shaped connecting plate 413. The L-shaped connecting plate 413 drives the first connecting rotating shaft 418 to realize that the end of the first flap 45 close to the pressing plate 48 is tilted upward, so that the first flap 45 pushes the workpiece 7 on the two supporting cross bars 44 in the first rectangular groove 42 into the guide groove 41, so that the workpiece 7 flows downstream and enters the second rectangular groove 417. After the workpiece 7 enters the second rectangular groove 417, it contacts the two rollers 415, and the two rollers 415 are connected by a connecting belt 416. One of the rollers 415 is connected to the driving motor 410 to achieve synchronous rotation of the two rollers 415, thereby effectively realizing the rotation of the workpiece 7; When the two rollers 415 drive the workpiece 7 to rotate, the electric push cylinder 3 on the top of the cover 2 drives the installation box 100 to move downward, and a hanger 11 is fixedly installed on the top of the installation box 100, so that when the electric push cylinder 3 drives the installation box 100 to move up and down, the position of the second polishing wheel 103 inside the installation box 100 and the workpiece 7 is effectively guaranteed to be accurate without deviation, thereby ensuring the polishing quality; When the installation box 100 moves downward, the matching frame 8 fixedly installed on one side of the installation box 100 moves downward at the same time, and the inclined edge of the triangular support 80 at the bottom of the matching frame 8 contacts the roller 54. The matching frame 8 passes through the through groove 500 provided on the Z-shaped frame 50 during the descending process, ensuring that the first polishing wheel 51 is moved to the inner surface of the workpiece 7, so that the polishing processing position of the inner wall is accurate; When the triangular support 80 squeezes the roller 54, the roller 54 is installed, and the support plate 55 drives the slide plate 59 to move forward along the slide rail 510 under the action of the squeezing force. After the installation box 100 stops descending, the first polishing wheel 51 just penetrates the inside of the workpiece 7, and the first motor 53 and the second motor 101 respectively drive the first polishing wheel 51 and the second polishing wheel 103 to realize synchronous polishing of the inner and outer surfaces of the workpiece 7, while ensuring the polishing quality, it also greatly improves the work efficiency; After polishing is completed, the electric push cylinder 3 drives the installation box 100 to move upwards, and at the same time, the matching frame 8 drives the triangular support 80 to separate from the roller 54, and the slide bar 56 at the end of the slide plate 59 passes through the second L-shaped plate 511. Under the action of the spring 57 set between the end of the slide bar 56 and the second L-shaped plate 511, the first polishing wheel 51 is driven to move backward, so that the first polishing wheel 51 is separated from the workpiece 7; At this time, the workpiece 7 is placed at the higher end of the tilting frame 40. During the rolling process of the workpiece 7, the workpiece 7 presses down the pressure plate 48. When the first flap 45 at the bottom of the first rectangular groove 42 tilts upward, the end of the first connecting shaft 418 away from the first connecting rod 47 is connected to the second connecting shaft 412 through the second connecting rod 49. When the first flap 45 flips upward, the first connecting shaft 418 simultaneously pulls the second connecting rod 49 and the second L-shaped connecting plate 414. The second L-shaped connecting plate 414 is installed with the second flap 411 through the second connecting shaft 412, and the end of the second flap 411 close to the first rectangular groove 42 tilts upward simultaneously, so that the processed workpiece 7 is pushed into the guide groove 41, and the workpiece 7 is automatically loaded and unloaded through the loading assembly 4, which reduces the participation of personnel and greatly improves work efficiency while ensuring the polishing quality.
