However, the scraper blade is relatively thin, and it is easy to clamp multiple scrapers when directly clamping, making it difficult to separate a single scraper blade. Summary of the invention

[0032] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0033] In the prior art, when the scraper is installed on the piston, it needs to be installed manually, which is time-consuming and laborious, and has low efficiency; when the automated production line is used for installation, the individual scrapers need to be separated in advance, such as Figure 2 As shown, the scraper blade is relatively thin, with a thickness of about 0.35 mm. It is difficult for the clamping device to accurately clamp a single scraper blade, and the scraper blade cannot be separated.

[0034] The present invention divides the materials by extruding a scraper.

[0035] like Figure 1-10 As shown, a scraper piston ring material distribution device comprises:

[0036] Platform 100;

[0037] The material storage column 200 comprises a material discharge plate 210 fixedly mounted at the bottom of the material storage column, wherein the gap between the lower bottom surface of the material discharge plate and the upper surface of the platform is greater than the height of one scraper blade and less than the height of two scrapers;

[0038] The extrusion device 300 is symmetrically arranged on both sides of the platform, and includes an extrusion plate 320, and the extrusion plates on both sides can move toward each other in the horizontal direction;

[0039] A clamping device 400 having a clamping assembly 430 for clamping a scraper blade;

[0040] A plurality of stacked scraper blades 10 can be placed on the material storage column, and the extrusion plate can squeeze one end of the scraper blade of the bottom layer, so that the scraper blade of the bottom layer moves horizontally and forms a protrusion 11 that is staggered from the unloading plate, and the clamping assembly can clamp the protrusion upward and drive the scraper blade of the bottom layer to move along the length direction of the platform; when the extrusion plate is squeezing the scraper blade of the bottom layer, the upper surface height of the extrusion plate is lower than the lower bottom surface of the scraper blade of the second layer.

[0041] The second layer of scraper blades herein refers to scraper blades adjacent to the lowest layer of scraper blades.

[0042] like Figure 6 As shown, in order to make a scraper blade break away from the interference with other scrapers, one end of the scraper blade can be squeezed, and the scraper blade will move horizontally toward the other end; in the horizontal direction, there is a certain gap between the squeezed scraper blade and the other scrapers, and the clamping jaws can extend into the gap and clamp the protruding part. At this time, other devices can be used to drive the clamping jaws to move horizontally to complete the material separation.

[0043] The scraper blade must be squeezed before it can be clamped. If you directly use the clamping assembly to try to clamp a single scraper blade, because the scraper blade is relatively thin and the control accuracy of the clamp is limited, it is easy to clamp multiple scrapers and fail to achieve material separation.

[0044] like Figure 5-7 As shown, the cross section of the blanking plate 210 is circular, and the extrusion plate extrudes one end of the bottom scraper blade to form the protruding portion 11 between the other end of the bottom scraper blade and the blanking plate.

[0045] When multiple scrapers are stacked on the material storage column, the upper surface of the bottom scraper should be lower than the lower surface of the unloading plate, and the inner diameter surface of the second layer of scrapers should be able to fit with the arc surface of the unloading plate, so that the unloading plate can position the second layer of scrapers. After the bottom layer of scrapers is clamped away by the clamping assembly, the second layer of scrapers can slide downward along the arc surface of the unloading plate and the positioning plate 240, and finally fall onto the platform.

[0046] The unloading plate is suspended above the platform with a certain gap between it and the platform, and the height of the gap must be greater than the height of a scraper blade so that after the clamping assembly clamps the scraper blade, it can be transported to other processes; but the gap needs to be smaller than the height of two scrapers. When the clamp clamps the bottom scraper blade and transports the scraper blade to other workstations, the unloading plate is needed to limit the second scraper blade to avoid the friction and adhesion between the bottom scraper blade and the second scraper blade causing the second scraper blade to be misplaced, thereby avoiding affecting subsequent production.

[0047] The side of the extrusion plate used for extruding the scraper blade is an extrusion surface 321, the two end points of the extrusion surface are point A and point B respectively, and the center of the cross section of the blanking plate is point O.

[0048] During the process from the start of the extrusion plate to the completion of the extrusion, point A moves to point A1, and point B moves to point B1.

[0049] like Figure 4 As shown, the extrusion device 300 includes an extrusion cylinder 310 , which has an extrusion piston rod that moves in a horizontal direction. The extrusion piston rod is fixedly connected to an extrusion plate 320 , and the extrusion cylinder is fixedly connected to the platform 100 .

[0050] like Figure 7 and 8 As shown, the extrusion cylinder pushes the extrusion plate to complete the extrusion action; after the scraper is squeezed, the clamping claw moves upward to clamp the protruding part.

[0051] like Figure 3 As shown, the clamping device further includes a transport assembly 410 capable of driving the clamping assembly to move in a horizontal direction, and a lifting assembly 420 capable of driving the clamping assembly to move in a vertical direction.

[0052] like Figure 3 As shown, the transport assembly 410 includes a linear electric cylinder 411 and a transport working part 412 driven by the linear electric cylinder to perform horizontal movement.

[0053] The transporting working part moves along the extending direction of the opening, thereby driving the lifting assembly and the clamping assembly to move.

[0054] like Figure 3 As shown, the lifting assembly 420 includes a horizontally arranged mounting plate 421, a vertically arranged support plate 422, and a lifting cylinder 423. The mounting plate 421 is fixedly connected to the transport working part 412, the lower end of the support plate 422 is fixedly connected to the upper surface of the mounting plate 421, and the lifting cylinder 423 is fixedly arranged on one side of the support plate 422. The lifting cylinder has a lifting piston rod that moves vertically.

[0055] like Figure 1 and 3 As shown, the clamping assembly 430 includes a support plate 431, a two-way cylinder 432 and a clamping claw 433 driven by the two-way cylinder to perform a clamping action, the lifting piston rod is fixedly connected to the lower surface of the support plate 431, and the two-way cylinder 432 is fixed to the upper surface of the support plate; the clamping device 400 is arranged under the platform 100, and the platform is provided with an opening 110 extending along the two ends of the platform, and the size of the clamping claw 433 is smaller than the size of the opening 110.

[0056] The lifting piston rod moves upward, which can drive a clamping claw to extend into the part between the protruding part and the arc surface of the blanking plate.

[0057] The clamping assembly is driven by a bidirectional cylinder to complete the clamping action.

[0058] like Fig. 9 and 10 As shown, the material storage column 200 also includes a connecting column 220, an upper end plate 230 and a positioning plate 240 for positioning the scraper; one end of the connecting column is fixedly connected to the lower surface of the upper end plate 230, and the other end is fixedly connected to the upper surface of the unloading plate 210; the positioning plate is vertically arranged, one end of which is fixedly connected to the lower surface of the upper end plate 230, and the other end is fixedly connected to the upper surface of the unloading plate 210; the material dividing device also includes a fixed column 250, one end of which is fixedly connected to the upper surface of the platform 100, and the other end is fixedly connected to the positioning plate 240.

[0059] The entire material storage column is fixedly installed on the platform through a fixing column, and a gap is provided between the lower surface of the material discharge plate and the upper surface of the platform, and the gap is greater than the height of a scraper.

[0060] A plurality of scrapers pass through the upper end plate and are sleeved on the outside of the connecting column. The scrapers have scraper openings. The positioning plate is clamped between the scraper openings so that all the scraper openings face one position. The bottom scraper is mainly positioned by the positioning plate.
