Description

Technical Field

[0001] This solution relates to the field of piston assembly, and particularly to a semi-circular bead automatic feeding structure. Background Art

[0002] A piston is a mechanical part that reciprocates along the cylinder axis in the cylinder of reciprocating piston internal combustion engines, compressors, pumps and other machinery. There are three forms of pistons: disc-shaped, cylindrical and cylindrical. During the assembly process, semi-circular bead gaskets of corresponding sizes need to be placed in the grooves above and below the piston respectively.

[0003] In the prior art, a feeding tray is connected to a bin. When semi-circular beads are needed, the semi-circular beads flow out of the bin. However, because the sizes of the semi-circular bead gaskets used for different pistons are different, it is very cumbersome to replace the semi-circular beads in the bin with corresponding sizes when changing pistons of different sizes. At the same time, during the feeding process, when too many semi-circular beads are fed instantaneously, the semi-circular beads at the picking end are easily squeezed out of the device, resulting in increased loss or the skew of the position of the semi-circular beads, and the installation of the next process cannot be carried out smoothly.

[0004] Therefore, a feeding structure is needed that can automatically feed semi-circular beads of different sizes and control the feeding rhythm. Summary of the Invention

[0005] This solution aims to solve the above problems by providing a semi-circular bead automatic feeding structure that can automatically feed semi-circular beads of different sizes and control the feeding rhythm to avoid excessive instantaneous feeding affecting production.

[0006] To achieve the above object, the technical solution adopted in this solution is: a semi-circular bead automatic feeding structure, including a feeding unit and a material feeding unit. The feeding unit includes at least one bin, the bottom plate of the bin can move up and down, and the feeding nozzle is connected to the suction pipe and communicates with the material feeding unit; for the material feeding unit, the feeding port of the feeding tray is connected to the other end of the suction pipe, and the dividing plate blocks the outlet of the feeding slide rail and can move left and right.

[0007] Further, both sides of the feeding tray are fixed on the bracket and are in an inclined state. The feeding port is arranged at the upper end of the feeding slide rail. The lower end of the feeding slide rail is attached to the dividing plate, and an upper cover is arranged on the top surface.

[0008] Further, for the dividing plate, the number of material picking ports corresponds to the feeding slide rail. The first connecting plate connected to the bottom is fixed on the second power structure, and the slide plate drives the first connecting plate to slide on the dividing track.

[0009] Further, the sensing device is a proximity sensor, including a first sensor and a second sensor;

[0010] Further, the first sensor is arranged on the bottom surface of the feeding tray, and the second sensor is arranged at the bottom of the material dividing plate.

[0011] Further, the bin body is inclined in the X-axis direction, a top cover is arranged at the top, and the feeding nozzle is connected to a limiting plate and passes through and is fixed in the bin;

[0012] A fixing member is arranged at the top of the support frame, and the bin is limited in the fixing frame connected to the top of the fixing member.

[0013] Further, the heights of the fixing members are different. The heights of the two fixing members on one long side are lower than those of the fixing members on the other long side, so that the bin is in an inclined state in the Y-axis direction.

[0014] Further, the bottom of the bin further includes a first power structure. The first power structure is fixed on the bracket, and the power end is fixed with a push block, and the push block pushes the bottom plate to move up and down along the Y-axis direction.

[0015] Further, a slider slidably connected to the feeding track is fixed at the bottom of the bottom plate, and the feeding track passes through and is limited at both ends of the bottom plate.

[0016] Further, a groove is arranged on one side of the top surface of the bottom plate close to the feeding nozzle.

[0017] In summary, the present solution has the following advantages:

[0018] 1. For the feeding unit provided by the present solution, by reasonably inclining the angles of the bin in the X-axis and Y-axis directions and combining with the bottom plate that moves up and down, the semi-spherical beads enter the feeding nozzle in the vertical direction, and a fixed amount is placed each time, avoiding blockage or loss caused by excessive instantaneous feeding amount;

[0019] 2. For the feeding unit provided by the present solution, the automatic control of the feeding progress and speed is realized through the induction device. After receiving the signal, different-sized gaskets can be provided for the piston, improving the production efficiency and being more intelligent. Description of the Drawings

[0038] The following further describes the solution in conjunction with the drawings and embodiments:

[0039] Embodiment 1:

[0040] A semi-spherical bead automatic loading structure, as Figures 1-9 shown, includes a loading unit 100 and a feeding unit 200 connected through a suction pipe (not shown).

[0041] The loading unit 100, as Figures 1-5 shown, a fixing part 111 is arranged at the top of the support frame 110, and a fixing frame 112 connected to the top of the fixing part 111 limits at least one magazine 120.

[0042] The heights of the fixing members 111 are different. The heights of the two fixing members 111 on one long side are lower than those of the fixing members 111 on the other long side, causing the storage bin 120 to be inclined in the Y-axis direction.

[0043] The storage bin 120 is used to store semi-circular beads. As Figures 1-3 shown, multiple storage bins 120 are arranged in combination, inclined in the X-axis direction, with a top cover 121 provided at the top, a feeding nozzle 122 provided on the side inclined downward in the Y-axis direction, and a bottom plate 123 that can move up and down at the bottom.

[0044] In this embodiment, eight storage bins 120 are provided, and different models of semi-circular beads are placed inside. The storage bin 120 is selected for feeding according to actual needs.

[0045] The top cover 121 is used to add and seal semi-circular beads, and a handle is included at the top.

[0046] As Figures 4-5 shown, the feeding nozzle 122 is an oblong through-hole, passing through and fixed on the storage bin 120. Inside the storage bin 120, the end of the feeding nozzle 122 is connected to a limiting plate 1221, and the limiting plate 1221 ensures that the discharging direction of the semi-circular beads will not be blocked due to too many semi-circular beads.

[0047] The bottom plate 123 is connected to a slider 1231 at the bottom, and the slider 1231 is slidably connected to a feeding track 125 fixed to a limiting post 124 below it. The feeding track 125 passes through and is limited at both ends of the bottom plate 123.

[0048] A groove is provided on one side of the top surface of the bottom plate 123 close to the feeding nozzle 122. After the semi-circular beads slide into the groove, the direction of the semi-circular beads is adjusted to the vertical state, facilitating rolling into the feeding nozzle 122 from the limiting plate 1221.

[0049] The bottom of the storage bin 120 further includes a first power structure 126. The first power structure 126 is fixed on a bracket, and a push block 1261 is fixed at the power end. The push block 1261 pushes the bottom plate 123 to move up and down along the Y-axis direction.

[0050] Specifically, when the first power structure 126 is started, the push block 1261 fixed at the power end of the first power structure 126 pushes the bottom plate 123. The bottom plate 123 drives the slider 1231 to slide on the feeding track 125 until it is in the same plane as the bottom of the feeding nozzle 122. The semi-circular beads in the storage bin 120 pass through the limiting plate 1221 and slide into the suction pipe from the feeding nozzle 122.

[0051] The feeding unit 100 provided by this solution makes the semi-spherical beads enter the feeding nozzle 122 in the vertical direction by reasonably tilting the angles of the X-axis and Y-axis of the silo 120 and combining with the bottom plate 123 that moves up and down, and a fixed amount is put each time, avoiding blockage or loss caused by excessive instantaneous feeding amount.

[0052] The feeding unit 200, as Figure 1 and 6 shown in Figures 7, 8, and 9, includes a feeding tray 220, a material dividing plate 230, and a sensing device 240 on a base 210. Feeding slide rails 221 connected to suction pipes are evenly distributed on the top surface of the feeding tray 220, and the material dividing plate 230 blocks the outlet of the feeding slide rails 221 and can move left and right.

[0053] The feeding unit provided by this solution realizes the automatic control of the feeding progress and speed through the sensing device 240. After receiving a signal, it can provide gaskets of different sizes for the piston, improving the production efficiency and being more intelligent.

[0054] As Figure 6 and 7 shown, both sides of the feeding tray 220 are fixed to the brackets and are in an inclined state in the Y-axis direction. An upper cover 222 is arranged on the top surface of the feeding slide rails 221, and the semi-spherical beads are sucked into the feeding port 2211 through the suction pipes, and the semi-spherical beads move along the feeding slide rails 221 towards the material dividing plate 230.

[0055] As Figure 6 , 8 shown in Figures 9, the material dividing plate 230 includes material taking ports 231 corresponding to the number of the feeding slide rails 221, a first connecting plate 211 connected to the bottom and fixed with a second power structure 232, and a sliding plate 233 is fixed to the bottom of the first connecting plate 211, and the sliding plate 233 slides on the material dividing track 234 on the base 210.

[0056] In this solution, the feeding slide rails 221 are connected to the silo 120 through suction pipes. In this embodiment, eight feeding slide rails 221 are also provided, and eight material taking ports 231 are also provided.

[0057] During the displacement of the first connecting plate 211, in order to ensure the accuracy of the position, limiting ends are further included on both sides of the first connecting plate 211.

[0058] As Figure 6 , 7 shown in Figures 9, the sensing device 240 includes a first sensor 241 and a second sensor 242.

[0059] The first sensor 241 is arranged on the bottom surface of the feeding tray 220 and is used to detect whether there is a shortage of materials;

[0060] Specifically, when the first sensor 241 fails to detect the number of semi-circular beads in the feeding slide rail 221, the first sensor 241 emits a signal, and the suction pipe supplements the semi-circular beads into the feeding slide rail 221 by suction.

[0061] The second sensor 242 is arranged at the bottom of the material distribution plate 230 and is used to detect whether a piston reaches the assembly station.

[0062] Specifically, when the piston reaches the assembly station, the material taking device transfers and inputs the semi-circular beads from the material taking port 231 into the assembly station.

[0063] In this embodiment, the sensing device 240 is a proximity sensor.

[0064] The second power structure 232 controls the displacement of the material distribution plate 230, controls the feeding rhythm of the semi-circular beads, ensures that the semi-circular beads at the material taking port 231 are in the correct position, and can be smoothly sent in and out of the feeding unit 200 by the feeding unit. In this embodiment, the second power structure 232 is a cylinder.

[0065] Specifically, when the material in the feeding slide rail 221 is insufficient, the first sensor 241 emits a signal, and the semi-circular beads in the material bin 120 are sucked into the feeding port 2211 through the suction pipe. The semi-circular beads slide downward along with inertia to reach the material taking port 231. Then, the second power structure 232 controls the first connecting plate 211 to drive the material distribution plate 230 to move along the material distribution track 234 on the sliding plate 233, and the protruding parts between adjacent material taking ports 231 block the outlet of the feeding slide rail 221.

[0066] When the second sensor 242 detects that the piston reaches the discharging unit, the feeding unit 200 sucks the semi-circular beads at the discharging port and transfers and puts them into the discharging unit.

[0067] When the semi-circular beads are taken away, a signal is emitted through the sensing device 240, and the second power structure 232 controls the first connecting plate 211 to drive the material distribution plate 230 to reset to the initial position along the material distribution track 234 on the sliding plate 233, and the semi-circular beads fall into the material taking port 231.

[0068] In summary, for the feeding unit provided in this application, by reasonably tilting the angles of the material bin in the X-axis and Y-axis directions and combining with the bottom plate that moves up and down, the semi-circular beads enter the feeding nozzle in the vertical direction, and a fixed amount is put each time, avoiding blockage or loss caused by excessive instantaneous feeding amount.

[0069] The feeding unit provided in this application realizes the automatic control of the feeding progress and speed through the sensing device. After receiving the signal, it can provide gaskets of different sizes for the piston, improving the production efficiency and being more intelligent.
