Abstract
The utility model relates to a valve-controlled vacuum deburring machine. The valve-controlled vacuum deburring machine is characterized in that a plurality of negative-pressure air suctioning holes are arranged on the surface of a vacuum working platform, and the back surfaces of the negative-pressure air absorbing holes are provided with air valves; and the combined parts of upper valve bodies and lower valve bodies of the air valves are provided with elastic valve chips for closing channels of upper valve body cavities and lower valve body cavities, and the elastic valve chips are in a normally-opened state under the non-working state. The valve-controlled vacuum deburring machine has the advantages that (1) the difficulty of automatic distribution of vacuum suctioning force which can not be solved by technical personnel in the field of deburring machines for long term is solved, the automatic opening or closing of the negative-pressure air-flow suctioning holes in the vacuum working platform of the deburring machine can be realized, the structure is simple, the self control is free and reliable, and the effect is good; (2) the vacuum suctioning force to a workpiece is greatly increased, so that the range of machinable workpieces is larger, and the machining for smaller workpieces becomes easy; and (3) not only can the energy consumption be reduced effectively, but also the machining cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of under the negative-pressure air-flow effect, on the flash trimmer vacuum work platform negative inspiratory pressure hole when workpiece hides, air valve opens, when no workpiece hid, the valve control vacuum flash trimmer that air valve is closed belonged to flash trimmer and makes the field.
Background technology
The applicant all formerly number of patent application 200910097298.1, titles " sander special negative pressure transport platform and carrying method "; Many idlers pitches are distributed in to carry on the stand and drive many carrying rollers by the chain wheel driving mechanism that sprocket wheel, chain constitute and rotate synchronously; Negative inspiratory pressure mouth in the negative pressure box is communicated with negative pressure ventilation machine negative pressure vacuum noz(zle); Have at the bottom of the case of the negative-pressure adsorption case between the many carrying rollers a plurality of pores and be positioned at it under the negative pressure box face on a plurality of pores communicate, the case face of many negative-pressure adsorption casees has a plurality of negative pressure and inhales the hole.Advantage be solved normal sands ray machine that background technology exists can't be to sanding less than the following thin skin of 0.5MM thickness, thin skin that can either the sand rolling.Shortcoming is: no matter whether a plurality of pores on the negative pressure box face have workpiece on it, all is in complete open state, and the air-flow that causes producing negative pressure unrestrictedly runs off; Making really needs the position negative pressure of negative-pressure air-flow absorption to reduce; Suction reduces, and workpiece can't be fixed when grinding, influences ground effect.
The utility model content
Purpose of design: avoid the weak point in the background technology; Design a kind of under the negative-pressure air-flow effect; When the negative inspiratory pressure hole has workpiece to hide in the flash trimmer negative pressure transportation platform, air valve opens, during no workpiece covering, the valve control vacuum flash trimmer that air valve is closed automatically.
Design: in order to realize above-mentioned purpose of design.Having the design that air valve is equipped with at a plurality of negative inspiratory pressures hole and the back side, negative inspiratory pressure hole on the table top of flash trimmer vacuum work platform, is the major technique characteristic of the utility model.The purpose of doing like this is: because the upper valve body of air valve and be provided with the design of feather valve chip with following valve body joint portion; Air valve is contained in the back side, negative inspiratory pressure hole on the flash trimmer vacuum work flat surface; The key that can air valve utilize negative-pressure air-flow to reach open and close is the feather valve chip; And be positioned at upper valve body and with the diameter of the feather valve chip of following valve body joint portion greater than valve body valve pocket diameter down; And feather valve chip elasticity is less than the negative-pressure sucking from following valve body opening; Therefore when the upper valve body mouth does not have workpiece, from the negative-pressure air-flow of valve body opening down the feather valve chip is pull-in on down on the sealing table top around the body cavity valve port, the upper valve body mouth does not have the negative-pressure air-flow generation at this moment; When the upper valve body mouth had workpiece, its upper valve body chamber and lower valve body cavity formed vacuum state, act directly on the workpiece and workpiece is firmly held from the negative-pressure air-flow of valve body opening down, and the feather valve chip of this moment is in opening.
Technical scheme: a kind of valve control vacuum flash trimmer; It comprises flash trimmer, and the rocking arm lower end is the rotation grafting with vacuum work platform table top and cooperates, and dual-axle motor is installed in the cylinder arm end through handle assembly; The dual-axle motor two ends are equipped with sand sheet brush and polish brush dish respectively; Have a plurality of negative inspiratory pressures hole on the table top of the vacuum work platform in the said flash trimmer, the back side, negative inspiratory pressure hole is equipped with air valve and is positioned at vacuum chamber, and the vacuum chamber outlet is not communicated with vacuum chamber; On the door of vacuum chamber axial flow blower is housed; Vacuum chamber is supported by lower bearing bracket, and vavuum pump is communicated with vacuum chamber through pipeline and whether controls its work by electric cabinet, the upper valve body of said air valve and be provided with the feather valve chip and the feather valve chip that are used to close upper valve body chamber and lower valve body cavity passage with following valve body joint portion and under off working state, be in normally open.
The utility model is compared with background technology; The one, solved the difficult problem that the insurmountable for a long time pull of vacuum of flash trimmer those skilled in the art is distributed automatically; Realized in the flash trimmer in the vacuum work platform the automatic unlatching of negative-pressure air-flow suction hole or closed, have simple in structure, automatic control freely, reliable, the effective advantage of automatic control; The 2nd, greatly improved pull of vacuum, but made the processing work scope bigger workpiece, to the processing of small workpiece more become easily; The 3rd, not only reduce the consumption of the energy effectively, and greatly reduced processing cost.
