Description

Technical Field

[0001] The invention relates to the field of automatic bolt-threading gaskets in rail transit vehicle manufacturing, and in particular to a vibration plate capable of automatically identifying the front and back sides of gaskets. Background Art

[0002] Most rail vehicle assembly operations rely on manual installation. For example, putting gaskets on bolts mainly relies on manual assembly, which requires a lot of manpower and time to meet the needs of production sites. The introduction of "bolt-through-gasket" assembly equipment can release the production capacity of the above employees, realize the automation and intelligent "bolt-through-gasket" assembly, and start and use it at any time.

[0003] The bolts and washers commonly used in non-customized equipment on the market are smaller in size and are mainly used for bolt tightening of small equipment. They do not have the function of automatically applying thread lubricant. Generally speaking, non-customized gasket insertion equipment only has a combination of "bolts, spring washers, flat washers" and rarely has the function of identifying the front and back of gaskets.

[0004] Reference Figure 1 , Figure 2 At present, the production method of gaskets is generally through stamping. The front and back sides of the stamped gasket 7 are different. The front side 71 is a circular arc surface with a larger diameter, and the back side 72 is a plane with a smaller diameter. The two are connected by an inclined surface 73. The front and back sides need to be distinguished during normal production or use. If the front and back sides are identified and screened one by one manually, the efficiency is low and the time is long, which will waste a lot of manpower and time, and bring inconvenience to production or use. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a vibration plate that automatically identifies the front and back sides of a gasket, which is conducive to improving the efficiency of subsequent automatic gasket threading.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a vibration plate for automatically identifying the front and back sides of a gasket, which includes a vibration plate provided with a discharge port, the discharge port position at the outer end of the vibration plate is surrounded by an inclined track, the bottom of the track is provided with a protrusion for supporting the bottom of the gasket in a vertical state, the width of the protrusion is the same as the thickness of the gasket, the protrusion is provided with an identification notch, the width of the identification notch is 1 / 3 of the thickness of the gasket, the tail end of the track is connected to a horizontal support plate, and an auxiliary guide bar for adjusting the gasket to a horizontal state is provided between the tail end of the track and the horizontal support plate.

[0007] According to some embodiments of the present invention, a pin is provided at the outer end of the vibration plate opposite to the identification notch, the height from the pin to the protrusion is between the highest point and the lowest point of the gasket edge, and the gap between the pin and the track is 1 / 3 of the gasket thickness.

[0008] According to some embodiments of the present invention, a mounting platform is provided on the vibration plate, and the ejector pin is fixed on the mounting platform by bolts.

[0009] According to some embodiments of the present invention, a reverse guide bar is provided between the tail end of the track and the horizontal support plate for adjusting the gasket to a reverse horizontal state.

[0010] According to some embodiments of the present invention, the reverse guide strip is a curved sheet that is bent inwardly.

[0011] According to some embodiments of the present invention, a mounting boss is provided on the vibration plate, and the reverse guide strip is fixed on the mounting boss by bolts.

[0012] According to some embodiments of the present invention, the horizontal support plate is in communication with a gasket output channel.

[0013] According to some embodiments of the present invention, the angle between the track and the vertical plane is 20° to 30°.

[0014] According to some embodiments of the present invention, a recycling box is provided at the bottom of the identification gap.

[0015] According to some embodiments of the present invention, the auxiliary guide bar is welded to the bottom of the horizontal support plate.

[0016] The present invention has at least the following beneficial effects: in this scheme, an identification notch is provided on the protrusion, and the width of the identification notch is 1 / 3 of the thickness of the gasket. If the front side of the gasket is attached to the track for transportation, since its front side is a circular arc surface, the contact area between its lower end and the protrusion is small. When the gasket passes through the identification notch, since the width of the protrusion becomes smaller and the contact area with the bottom of the gasket becomes smaller, the gasket will fall from the identification notch, thereby ensuring that the front side of the gasket is in a horizontal state facing upward and enters the horizontal support plate, which is convenient for the accurate output of the gasket and is beneficial to improving the efficiency of subsequent automatic gasket threading.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figure 3 , Figure 4 A vibrating plate for automatically identifying the front and back sides of a gasket comprises a vibrating plate 1 provided with a discharge port 11, and a track 2 arranged in an inclined manner surrounds the discharge port 11 at the outer end of the vibrating plate 1, referring to Figure 5, the angle c between the track 2 and the vertical plane is 20°~30°. The bottom of the track 2 is provided with a protrusion 21 for supporting the bottom of the gasket in a vertical state, and the width of the protrusion 21 is the same as the thickness of the gasket. The protrusion 21 is provided with an identification notch 22, and the width of the identification notch 22 is 1 / 3 of the thickness of the gasket. The tail end of the track 2 is connected to the horizontal support plate 3, and an auxiliary guide bar 5 for adjusting the gasket to a horizontal state is provided between the tail end of the track 2 and the horizontal support plate 3. In order to ensure stable installation, the auxiliary guide bar 5 is welded to the bottom of the horizontal support plate 3. When in use, first place a plurality of gaskets 7 in the vibration disk 1, and through the vibration of the vibration disk 1, slide the gasket 7 out of the discharge port 11 and into the track 2. After the gasket 7 slides into the track 2, it moves toward the horizontal support plate 3. At this time, the bottom end of the gasket 7 abuts against the protrusion 21, and the side of the gasket 7 relies on the track 2. When the gasket 7 passes through the identification notch 22 during the vibration process, refer to Figure 5 If the back side 72 of the gasket 7 is attached to the track 2 during transportation, the gasket 7 will pass through the track 2, and under the vibration of the auxiliary guide bar 5, the front side 71 of the gasket 7 will face upward and enter the horizontal support plate 3 in a horizontal state. Figure 6 When the front side 71 of the gasket is transported on the track, since the front side 71 is a circular arc surface, the contact area between the lower end and the protrusion 21 is small. When the gasket 7 passes through the identification notch 22, the protrusion 21 becomes smaller in width and the contact area with the bottom of the gasket 7 becomes smaller, so the gasket 7 will fall from the identification notch 22. In order to facilitate collection, a recycling box is provided at the bottom of the identification notch 22. It is convenient to put the gasket 7 in the recycling box back into the vibrating plate 1 for secondary screening.

[0029] If the gasket 7 has not fallen off during the transport vibration process, the outer end of the vibration plate 1 is provided with a pin 4 opposite to the identification notch 22, and the height from the pin 4 to the protrusion 21 is between the highest point and the lowest point of the gasket edge. Figure 2 At the height b position, the gap between the ejector pin 4 and the track 2 is 1 / 3 of the thickness of the gasket. If the front side 71 of the gasket 7 is attached to the track 2 for transportation, the arc surface with a larger diameter will be forcibly ejected by the ejector pin 4. When the back side 72 of the gasket 7 is attached to the track 2 for transportation, the ejector pin 4 will be located at the inclined surface 73 with a smaller diameter of the gasket 7, and the gasket 7 can pass normally.

[0030] In order to facilitate installation, a mounting platform 13 is provided on the vibration plate 1, and the ejector pin 4 is fixed on the mounting platform 13 by bolts.

[0031] If the reverse side 72 of the gasket 7 is required to face upward and enter the horizontal support plate 3 in a horizontal state, a reverse guide bar 6 is provided between the tail end of the track 2 and the horizontal support plate 3 to adjust the gasket to a reverse horizontal state. The reverse guide bar 6 is a curved sheet bent inward. For easy installation, a mounting boss 14 is provided on the vibration plate 1, and the reverse guide bar 6 is fixed on the mounting boss 14 by bolts. In order to facilitate the collection and identification of the gaskets 7 on the front and back sides, the horizontal support plate 3 is connected to the gasket output channel.

[0032] In this solution, an identification notch 22 is provided on the protrusion 21, and the width of the identification notch 22 is 1 / 3 of the thickness of the gasket. When the front side 71 of the gasket is transported on the track, since the front side 71 is a circular arc surface, the contact area between the lower end and the protrusion 21 is small. When the gasket 7 passes through the identification notch 22, since the width of the protrusion 21 becomes smaller and the contact area with the bottom of the gasket 7 becomes smaller, the gasket 7 will fall from the identification notch 22, thereby ensuring that the front side 71 of the gasket 7 is in a horizontal state facing upward and enters the horizontal support plate 3, which is convenient for the accurate output of the gasket 7 and is beneficial to improving the efficiency of subsequent automatic gasket threading.

[0033] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
