Among them, scrapers are light in weight and thin in thickness, with a thickness of generally around 0.35mm. During the piston ring installation process, the scraper needs to be installed into the scraper slot on the piston.

The efficiency of manual ring installation is not only low, but also the labor intensity is particularly high due to the thin thickness, and the scraper blade is easily damaged by manual labor.

[0043] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0044] 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 installing it using an automated production line, it is necessary to separate the individual scrapers 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.

[0045] The present invention divides the materials by extruding a scraper.

[0046] like Figure 1-10 As shown, a scraper material distributing and assembling device comprises a scraper material distributing device and a scraper assembling device, wherein the scraper material distributing device comprises:

[0047] Platform 100;

[0048] 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;

[0049] 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;

[0050] A clamping device 400 having a clamping assembly 430 for clamping a scraper blade;

[0051] A plurality of stacked scrapers 10 can be placed on the material storage column, and the extrusion plate can squeeze one end of the scraper at the bottom layer, so that the scraper at the bottom layer moves horizontally and forms a protrusion 11 staggered from the material discharge plate, and the clamping assembly can clamp the protrusion upward and drive the scraper at the bottom layer to move along the length direction of the platform; when the extrusion plate is squeezing the scraper at the bottom layer, the upper surface height of the extrusion plate is lower than the lower bottom surface of the scraper at the second layer;

[0052] The scraper blade assembly device can expand the inner diameter of the scraper blade and install the scraper blade into the scraper blade groove on the piston.

[0053] The second layer of scraper blades herein refers to scraper blades adjacent to the lowest layer of scraper blades.

[0054] like Figure 6As 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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 .

[0062] like Figure 7 and 8As 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.

[0063] 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.

[0064] 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.

[0065] The transporting working part moves along the extending direction of the opening, thereby driving the lifting assembly and the clamping assembly to move.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] The clamping assembly is driven by a bidirectional cylinder to complete the clamping action.

[0070] like Fig. 9 and 10As 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.

[0071] 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.

[0072] 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.

[0073] The scraper blade material dividing device also includes a shelf plate 700, on which a plurality of shelf openings 710 are arranged. The number of the shelf openings is the same as the number of the claw components. In the present embodiment, the number of the shelf openings is 6, and the shelf openings are arranged in a star-shaped radial shape. The clamping assembly 430 transports the scraper blade to the shelf plate 700, and makes the center of the scraper blade roughly coincide with the intersection point of the center lines of the plurality of shelf openings. After the clamping assembly places the scraper blade on the shelf plate, it will loosen the clamping jaws 433, so that the clamping jaws are out of contact with the scraper blade, thereby completing the transportation of the scraper blade.

[0074] like Fig.12 As shown, the scraper assembly device of the present invention is installed on a ring assembly machine. Specifically, the fixed plate is installed on the ring assembly machine. The ring assembly machine has a rotating electric cylinder capable of driving the scraper assembly device to rotate and a lifting electric cylinder capable of driving the scraper assembly device to move up and down. The scraper assembly device of the present invention includes a fixed plate 500, a clamping mechanism for grabbing the scraper is connected to the lower end surface of the fixed plate, and a circular through hole 510 is provided in the middle position of the fixed plate, as shown in FIG. Fig.12 As shown, the fixing plate may preferably adopt a circular plate structure.

[0075] like Fig.11 As shown, the clamping mechanism includes a plurality of claw members 600 evenly distributed around the circular through hole and connected to the bottom surface of the fixing plate 500. Preferably, 3 to 6 claw members are provided. Fig.12 and Fig.13 As shown, there are six claw parts.

[0076] like Fig.11As shown, each of the claw components includes a mounting frame 610, and the mounting frame is arranged below the fixed plate. As shown in the figure, the mounting frame is an inverted L-shaped structure, wherein the vertical plate in the mounting frame is close to the circular through hole 510, and a pull ring assembly 620 and a support ring assembly 630 are respectively connected to both sides of the vertical plate, wherein the pull ring assembly is fixedly connected to one side surface of the mounting frame facing the circular through hole, for contacting the scraper blade from top to bottom and at the same time contacting the inner diameter surface of the scraper blade; wherein the support ring assembly is fixedly connected to the other side surface of the mounting frame, for contacting the scraper blade from bottom to top, and cooperating with the pull ring assembly to clamp the scraper blade.

[0077] like Fig.13 As shown, the pull ring assembly 620 includes a pull ring cylinder 621 fixedly connected to the vertical plate and vertically arranged, the pull ring cylinder is a slide cylinder, a vertical movable plate 622 is fixedly connected to the outer side of the slide plate of the pull ring cylinder, a lower pressure block 623 is connected to the lower end of the vertical movable plate, and a pull plate 624 is fixedly connected to the outer side surface of the lower pressure block toward the inner side of the fixed plate, the upper end surfaces of the pull plate and the lower pressure block are in the same horizontal plane, and the length of the pull plate is greater than the length of the lower pressure block, so that the pull plate can contact the inner diameter surface of the scraper blade when the lower pressure block contacts the scraper blade.

[0078] like Fig.14 As shown, a further arrangement of the pull ring assembly is that a limit screw 625 is connected to the bottom surface of the fixed end of the pull ring cylinder and faces the bottom surface of the slide plate of the pull ring cylinder. The slide plate contacts the limit screw during the downward movement, thereby limiting the downward position of the slide plate by the limit screw.

[0079] like Fig.14 As shown, the support ring assembly 630 includes an upper and lower support ring cylinder 631 which are fixedly connected to the vertical plate of the mounting frame 610 and are vertically arranged. The upper and lower support ring cylinders are slide cylinders. A connecting frame 632 is fixedly connected to the outer side surface of the slide plate of the slide cylinder. The connecting frame adopts an L-shaped structure. The vertical plate of the connecting frame is connected to the slide cylinder. A transverse support ring cylinder 633 is fixedly connected under the transverse plate of the connecting frame. The transverse support ring cylinder is a slide cylinder. The telescopic direction of the transverse support ring cylinder is toward the direction of the pull ring assembly. A support block connecting frame 634 is connected to the bottom surface of the slide plate of the transverse support ring cylinder.

[0080] like Fig.14As shown, the support block connecting frame 634 includes a horizontal plate 634-1 connected to the bottom surface of the slide plate of the horizontal support ring cylinder, a vertical plate 634-2 connected to one end of the bottom end surface of the horizontal plate, and a long rod 634-3 connected to the bottom end surface of the vertical plate and extending toward the pull ring assembly, and an upper support block 635 is connected to the end surface of the long rod, so that after the pull ring assembly is in contact with the scraper blade, the horizontal support ring cylinder is first started, prompting the support block connecting frame 634 to drive the upper support block to move below the scraper blade, and after the upper support block moves to below the scraper blade, the upper and lower support ring cylinders are started, prompting the support block connecting frame to drive the upper support block to move toward the scraper blade, and make the upper support block contact with the lower surface of the scraper blade, so as to achieve the lower pressure block and the upper support block clamping the scraper blade.

[0081] like Fig.14 As shown, a further arrangement of the support ring assembly is that a vertical plate 636 is fixedly connected to the connecting frame, and a vertically arranged stroke positioning screw 637 is provided on the upper end surface of the vertical plate. By adjusting the depth of the stroke positioning screw, the height of the upper support block when the upper and lower support ring cylinders are retracted is adjusted to ensure that multiple upper support blocks are on the same plane.

[0082] A further technical solution of the present invention is that the mounting frame 610 can be connected to the fixing plate 500 through a telescopic assembly 640, such as Fig.14 As shown, the telescopic assembly includes a telescopic cylinder 641 fixedly connected to the fixed plate, the telescopic cylinder adopts a slide cylinder, and the slide plate of the slide cylinder is an L-shaped structure, the slide plate is telescoped toward the circular through hole, a fixing frame 642 is fixedly connected to the side of the slide plate of the slide cylinder, and the mounting frame 610 is fixedly connected to the bottom surface of the slide plate; wherein, a vertically arranged roller 643 is connected to the fixing frame, that is, the grasping mechanism is provided with a plurality of rollers, and the plurality of rollers are evenly distributed in the circular through hole, the telescopic cylinder is always in an inflated and extended state, and when the roller is not subjected to force, the diameter of the circle formed by the plurality of rollers needs to be smaller than the circle The diameter of the through hole is a vertical pushing and pulling shaft can be arranged above the circular through hole. The pushing and pulling shaft moves downward along the circular through hole and contacts with multiple rollers. After applying force to the rollers, the telescopic cylinder connected to the fixing frame is retracted, thereby realizing the movement of the mounting frame and the pull ring assembly, thereby causing the pull plate in the pull ring assembly to apply force to the inner diameter of the scraper blade, and the pull plates in the multiple claw components simultaneously apply force in different directions to the inner diameter of the scraper blade, thereby expanding the scraper blade; after the ring is installed, the pushing and pulling shaft moves upward and loses contact with the rollers, and the extended state of the telescopic cylinder prompts the mounting frame and the pull ring assembly to return. It can be seen that the setting of the telescopic assembly can make the multiple claw components expand and contract evenly.

[0083] For example, the telescopic cylinder has a stroke of 40mm, when it is retracted, the diameter of the six claws is 30mm, and when it is expanded, the diameter of the six claws is 510mm, so the diameter range of the rings that can be automatically grasped is 35mm-105mm, which largely meets the actual needs of ring installation.

[0084] Usage process:

[0085] When the piston turns to the scraper blade installation station, the rotating electric cylinder installed on the ring installation machine drives the scraper blade assembly device to move as a whole to the top of the scraper blade, and the ring-pulling cylinder extends downward, so that the lower pressure block and the pull plate descend to the position limited by the limit screw; at this time, the lifting electric cylinder on the ring installation machine drives the entire scraper blade assembly device to descend, so that the lower pressure block contacts the upper surface of the scraper blade, and the vertical plate 634-2 and the long rod 634-3 on the support block connecting frame 634 enter the shelf opening 710, and then the horizontal support ring cylinder extends , so that the upper support block is directly below the scraper blade, and the upper and lower support ring cylinders are retracted, so that the upper support block contacts the lower surface of the scraper blade, thereby supporting the scraper blade. At this time, the scraper blade is clamped by the upper support block and the lower pressure block; the cylinder on the ring installation machine that causes the push-pull shaft to descend is started, so that the push-pull shaft moves downward to exert force on the roller, so that the telescopic cylinder is retracted, and multiple claw parts are evenly expanded, so that the scraper blade is expanded. Due to the lateral limiting effect of the pull ring cylinder, the radial retraction of the scraper blade can be prevented, thereby completing the grabbing and expansion of the scraper blade;

[0086] After the ring is taken out, the lifting electric cylinder of the ring installation machine drives the entire scraper assembly device to rise, and under the action of the rotating electric cylinder, the scraper assembly device is moved as a whole to the upper part of the piston, and then the scraper assembly device is lowered, so that the clamped scraper and the scraper slot are located on the same plane, the ring pulling cylinder retracts, the clamping force of the lower pressure block and the upper support block on the scraper is insufficient, and the scraper automatically shrinks and bounces into the scraper slot of the piston; at this time, the upper and lower ring supporting cylinders extend, the horizontal ring supporting cylinder retracts, and the lifting electric cylinder rises, so that the scraper assembly device rises, the ring installation is completed, and the next cycle is carried out.
