Description

Mechanism is stored with raw materials to punching press pay-off

Technical Field

The utility model belongs to the technical field of machining, concretely relates to punching press is raw materials storage mechanism for pay-off.

Background

The shape of the outer cover of the motorcycle primary clutch is shown in figure 1, which is formed by punching and punching a circular plate workpiece raw material as shown in figure 2. In the traditional process, the circular plate workpiece is generally manually conveyed to a stamping station for stamping and forming of the workpiece, and manual feeding is low in efficiency, high in labor cost and high in safety risk.

The applicant intends to adopt the conveyor belt to cooperate with the manipulator to feed the workpiece, but in the practical application process, because the positions of the workpiece on the conveyor belt are not completely and evenly distributed at intervals, when the manipulator grabs the workpiece from the conveyor belt, the position where the manipulator grabs the workpiece has certain deviation (the position where the manipulator grabs the workpiece should be located at the center of the workpiece, and the meaning that the position where the manipulator grabs the workpiece has deviation means that the position where the manipulator grabs the workpiece is actually located at the eccentric position of the workpiece), and after the manipulator grabs the workpiece to the punching station, the workpiece has deviation on the punching station, so the shape of the workpiece after punching forming has deviation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a punching press is raw materials storage mechanism for pay-off to the problem of deviation takes place easily when solving the manipulator pay-off.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a raw material storage mechanism for stamping and feeding comprises a rotary table, wherein a plurality of material bins for stacking workpieces are arranged on the rotary table, the material bins are annularly arranged, and lifting bearing trays are arranged in the material bins; the revolving stage outside is equipped with the adjustment station, is equipped with on the adjustment station and pushes away the material spare and keep off the material spare, it sets up with pushing away the material spare relatively to keep off the material spare.

Further, the feed bin comprises a plurality of material blocking columns which are annularly arranged, and the lifting bearing tray is located on the inner side of the material blocking columns.

Further, the adjusting station comprises a T-shaped frame located on the outer side of the rotating table, the T-shaped frame comprises a vertical rod and a horizontal rod, a discharging transverse plate is further fixed on the horizontal rod, and a material blocking piece is fixed on the discharging transverse plate.

Furthermore, the material pushing part comprises an adjusting cylinder fixed on the cross rod, and the pushing of the workpiece on the material placing transverse plate is realized through the extension of an output rod of the adjusting cylinder.

Furthermore, a material pushing plate is fixed on the output rod of the adjusting cylinder and is arc-shaped.

Further, the material blocking piece comprises two material blocking blocks which are distributed in a splayed shape, and the material blocking blocks are fixed on the discharging transverse plate.

Further, the number of the bins is four.

Further, still include the brace table that is located the revolving stage below, the revolving stage bottom coaxial fixation has the pivot, the pivot rotates to be connected in the brace table.

Furthermore, a lifting cylinder is fixed at the bottom of the rotating platform, and an output rod of the lifting cylinder is fixedly connected with the bottom of the lifting bearing plate.

The utility model discloses a principle and beneficial effect lie in:

the utility model discloses improve current conveyer belt pay-off mode and pile up the rotatory pay-off mode of cooperation feed bin for the work piece in the feed bin, manipulator pay-off in-process, the lift of the lift bearing dish that sets up in the feed bin can drive the work piece on it and go up and down, guarantee after the manipulator snatchs the work piece, because the reduction of work piece quantity leads to the work piece height that is located the top in the feed bin to reduce and influence snatching of manipulator in the feed bin, work piece is snatched the back in the feed bin, it rises to bear the dish through the lift, thereby guarantee that the manipulator can snatch the work piece that is located the top. The horizontal position of the workpiece in the stock bin is unchanged, so that the central position of the workpiece can be always grabbed by the manipulator, and the feeding deviation is avoided.

Set up the structure of a plurality of feed bins, each feed bin can alternate use, and the back has been snatched by the manipulator to work piece in one of them feed bin, can be through the rotation of revolving stage, and the feed bin that fills with the work piece with another is rotatory to being close to adjustment station department, and what the manipulator of being convenient for snatched, empty feed bin is rotatory to the position of keeping away from the adjustment station conveniently carries out the feed supplement to it, avoids needing the condition that could the feed supplement after the manipulator stop work, has improved material loading degree of automation.

If the rotating table rotates and the bin close to the adjusting station is slightly deviated in position due to loose parts or other reasons (for example, the outer diameter of the workpiece is slightly smaller than the inner diameter of the bin, and the position of the workpiece in the bin is slightly deviated), the position of the workpiece in the bin, which is grabbed by the manipulator, is still slightly deviated. The utility model discloses a manipulator snatchs the work piece to the adjustment station in from the feed bin, then the manipulator loosens the work piece, pushes away on the adjustment station that the material piece promotes the work piece and slides the certain distance a little until the work piece is stopped by keeping off the material piece, and the work piece is adjusted to the correct position promptly, and the manipulator snatchs the work piece again. The utility model discloses because the position of adjustment station is fixed all the time, through keeping off the material spare and pushing away the cooperation of material spare, can rectify the position of work piece, guarantee that the manipulator can snatch the correct position of work piece.
