The automatic displacement device of plate clamp
Technical field
The utility model is a kind of sheet metal process equipment that is applied to self-feeding, and as the numerical control rotating tower punch, the device that can make the clamp of clamping plate carry out automatic displacement belongs to Machine Design manufacturing technology field.
Background technology
For as sheet metal process equipments such as numerical control rotating tower punch, plate to be processed generally by be connected on the planker the clamp clamping on one side, plate moved and locate by the lathe automatic feeding system.Because plate size and Working position is different, needs its installation site on planker of the in good time conversion of clamp, makes it distribute reasonable and avoid processing the dead band.This requires clamp not only to be convenient to move locking but also locate accurately reliable on planker.(as shown in Figure 1) planker 1 adopts the dovetail respective outer side edges to be connected with grip module 3, embed dovetail briquetting 2 only moving up and down therebetween, screw rod 4 upper ends are fixed with handle 5, the lower end screws in grip module 3 and touches dovetail briquetting 2, thereby by artificial turning handle 5, grip module 3 and planker 1 are unclamped and lock.This mechanism has characteristics such as compact conformation, the location is reliable, displacement is convenient, is widely used always.But its manually-operated shortcoming also is conspicuous, and it has not only interrupted the sequencing operation of lathe, and can have the hidden danger of manually-operated error.This is unfavorable for the further raising of Machinery Tool Automation degree, more can not satisfy the requirement that emerging flexible manufacturing technology is used.
Summary of the invention
The utility model provides a kind of and can set instruction in procedure at the problems referred to above of clamp existence in the past, realizes the automatic displacement device of the plate clamp of clamp displacement automatically.
Technical characterictic of the present utility model is to adopt automatic voussoir retaining mechanism to substitute above-mentioned hand screw briquetting device, is provided by cylinder and spring and unclamps and locking power.
But automatic displacement operation is carried out in the instruction of clamp follow procedure automatically.By the positioning and locking controlling organization, with clamp and workbench locking, open automatic voussoir retaining mechanism simultaneously, make clamp and planker release, adjust the relative position of clamp and planker.
Below introduce structure of the present utility model in detail.A kind of automatic displacement device of plate clamp, form by automatic voussoir retaining mechanism of clamp and positioning and locking controlling organization, it is characterized in that the automatic voussoir retaining mechanism of clamp is by the dovetail briquetting that is positioned at planker dovetail lower edge, its bottom surface is two symmetrical inclined-planes, two symmetrical inclined-planes and the very heavy mechanism of the corresponding formation of the lozenges of left voussoir and right voussoir, there is locking spring to embed among the interior blind hole of left and right voussoir between left side voussoir and the right voussoir, the two ends of left side voussoir and right voussoir have corresponding unlock cylinder respectively, and the cylinder rod of unlock cylinder is connected with the end of left and right voussoir.
Grip module is installed on the planker, is connected with dovetail with planker, and the dovetail briquetting is as the part of grip module dovetail, translation up and down, and its bottom surface is two symmetrical inclined-planes; Left side voussoir and right voussoir symmetric arrangement, its ramp cooperates with dovetail briquetting and lower shoe by the plane needle bearing respectively with lower plane; Locking spring is installed in the middle of both, and its lateral surface is subjected to cylinder rod and adjustment screw effect.The spring force of horizontal direction is converted into the thrust of dovetail briquetting to the dovetail face of planker through double inclined plane, utilizes the power transmission of cotter mechanism to amplify and reverse latching characteristics, guarantees grip module positive lock on planker.
When the ventilation of unlock cylinder afterbody, cylinder rod stretches out, and promotes left and right voussoir and slides relatively, and its ramp position is moved, and causes the dovetail briquetting to descend thereupon, thereby removes its thrust to the planker dovetail.
The positioning and locking controlling organization comprises the positioning support that is installed on the lathe stationary work-table, positioning support one side is installed positioning cylinder, with the fastening connecting plate that links to each other of the cylinder rod of positioning cylinder, be fixed with the jacking block that embeds in the positioning support and an end of block on the connecting plate, corresponding ejector pin of the other end of jacking block and valve push rod formation transmission mechanism; The corresponding formation grip module of locating hole locking mechanism on the other end of block and the lower shoe of grip module.
When carrying out automatic displacement operation, move with planker by the programme-control grip module, stop at the position that its valve push rod lower end is right against ejector pin, positioning cylinder action this moment, driving block and jacking block rises, the former inserts in the locating hole of lower shoe, latter's jack-up valve push rod touches machine control valve then, makes the unlock cylinder action, unclamp planker, planker moves along the lathe X-axis then, and then grip module produces reverse displacement to it, and last positioner restores, grip module recovers lock-out state thereupon, finishes whole displacement process.
The utility model is kept other functions, structure and the profile of former clamp, has realized that both interchangeability is installed.Eliminate artificial displacement operation and can't make the lathe overall process shortcoming of operation automatically, improved production efficiency.And can carry out the automatic displacement of clamp in service of program, thoroughly eliminate the processing dead band that clamp brings.Especially for this kind equipment in the flexible manufacturing system (FMS), the automatic deflection function of clamp more is absolutely necessary.
