Description
Technical field
The present invention relates to electrode contact Storage Box (Electrode tip magazine), its accommodation is multiple for changing the replacing electrode contact that resistance welding machine uses.
Background technology
As the juncture of the workpiece such as metal, electric resistance welding is widely known by the people.Have as the welding gun in this electric resistance welding: the one-sided welding gun etc. possessing the C type of the electrode arranged in opposite directions for a pair or the crimping of the side from the workpiece welding electrode of X-type welding gun or series welding (series welding) or indirect welding (indirect welding) etc.
This electric resistance welding is: the electrode contact being arranged on the front end of arm (arm) by elongate portion (shank) is crimped on workpiece, On current under pressurised conditions, passes through produced joule's heat energy melting workpiece and the method engaged.Because electrode contact there will be consumption, shaggy phenomenon along with use, therefore reach when electrode contact consumption use boundary time or when from use through official hour, be necessary to change with the electrode contact do not used or grind again.
The replacing being arranged on the electrode contact of welding gun is needed as: do not stop production line, and automatically changes at short notice.Therefore, take off device at the electrode contact taking off electrode contact from welding gun that is nearby configured for of welding robot, be filled with the electrode contact Storage Box etc. of multiple new electrode contact, automatically carry out replacing operation with this.
That is, when electrode contact arrives replacing period, welding gun towards electrode contact take off device near and carry out the operation of being taken off from elongate portion by electrode contact.Then, welding gun towards electrode contact Storage Box near and the front end of elongate portion is inserted into the electrode contact of the position being positioned at regulation, with this, new electrode contact is embedded in elongate portion.Patent document 1 records the example that contact takes off device.
Fig. 8 (a) illustrates an example of electrode contact.Electrode contact 70 is in slightly cylindric, and the side, front end 71 being crimped on workpiece is formed as curved surface, and base portion 72 side of inserting elongate portion is formed with patchhole 73.The front end of patchhole 73 and elongate portion is all formed as taper (taper) face, and is fitted together to by these conicoids.
According to Fig. 9, the electrode contact Storage Box of patent document 2 is described.A () is the profile of electrode contact Storage Box 80; B () is for taking off plane during top cover 81.
The inside of electrode contact Storage Box 80 is formed with the accommodation passage 90 of the arc-shaped can holding multiple electrode contact 70.Multiple electrode contact 70 with the base portion 72 with patchhole 73 towards top cover 81 and the state contacted with each other be contained in and hold passage 90, and be pushed sheet (piece) 83 and counterclockwise energize (paying Potential).
Push-pads 83 is energized by clockwork spring 84, when the electrode contact 70B being positioned at anticlockwise terminal position be pushed sheet 83 energize time, the whole electrode contact 70 to the electrode contact 70A being positioned at front position is pushed.
The position of the electrode contact 70A of front end be electrode contact 70A by the position of choosing, and be the position that the elongate portion of welding gun enters.The part corresponding with this electrode contact 70A of top cover 81 is cut and be formed with conveying end 82.If insertion elongate portion, then electrode contact 70A is embedded in the front end of this elongate portion, and along with the retrogressing of this elongate portion, this electrode contact 70A is taken out by electrode contact Storage Box 80.
In other words, front position residing for electrode contact 70A is next time by the replacing holding fix of choosing, if electrode contact 70A is chosen, then the entirety of multiple electrode contact 70 moves the suitable length of its external diameter, thus makes originally to be positioned at and move to front position from the electrode contact 70 of the position of front end second and become the state changed and wait for.Finally, the electrode contact 70B being positioned at terminal position becomes the state changed and wait for, if the electrode contact 70B of this terminal position is chosen, then electrode contact Storage Box 80 becomes interior dummy status.
When the electrode contact 70 be arranged in accommodation passage 90 moves towards conveying end 82, front end 71 is moved with the state of swiping with outer circumferential side wall portion 92 and inner circumferential side wall portion 93 respectively with bottom wall part 91, outer peripheral face 74.And in inner circumferential side wall portion 93 side, electrode contact 70 does not contact with clockwork spring 84 and moves, and front end 71 is moved with the state of swiping with base portion side guide surface 96 with front guide surface 95, base portion 72.These electrode contacts 70 can be stably configured at conveying end 82 place by its result successively.
Usually, if repeatedly carry out weld job, then the front end of electrode contact 70 is out of shape, wears away, and the metal etc. of this front end attachment workpiece, is therefore difficult to carry out stable weld job, and failure welding phenomenon occurs.Therefore, be necessary regularly carry out grinding, grinding etc. to the surface of electrode contact 70 and repair, and for carrying out dressing operation, be necessary to regularly replace electrode contact 70.Although the electrode contact 70 after finishing shortens than new product total length, if do not reach use boundary, then can also reuse in weld job.
But, electrode contact after finishing 70 with do not use the electrode contact 70 of (new product) together to fill in electrode contact Storage Box 80, therefore there is the electrode contact 70 that length differs, thus the phenomenon of contact area inequality between generating electrodes contact 70, and then the pushing force coming from push-pads 83 suffered by each electrode contact 70 is uneven and electrode contact 70 easily tilts, therefore in the way holding passage 90, conveying end 82 place causes tilting, topples over and can not supply electrode contact 70 toward conveying end 82 definitely.In addition, the frictional force difference that contact area between electrode contact 70 and accommodation passage 90 is uneven and respective, electrode contact 70 is easily stuck in and holds in passage 90, therefore in the way holding passage 90, conveying end 82 place causes tilting, topples over and can not supply electrode contact 70 toward conveying end 82 definitely.Therefore, the new problem that cannot find when can there is the electrode contact (electrode contact that direction of principal axis length is all identical) 70 being only filled with new product.
In addition, except the electrode contact Storage Box of the configuration that contacts with each other between the electrode contact described in such as patent document 1 and patent document 2, also just like the form that electrode contact is held independently of each other described in patent document 3.In this form, be not in contact with each other between electrode contact, and by the coil spring at the center that is arranged on drum type (drum) weld cap holder 31, the drum type weld cap holder 31 maintaining weld cap K (electrode contact) is rotated and weld cap K is moved to obtains opening 40 (conveying end).The acquisition opening 40 being formed in the Storage Box lid 4 of drum type weld cap holder 31 is provided with stopper section 32, rotates and the weld cap K that arrives abuts with this stopper section 32 and weld cap K is positioned at obtain opening 40 place.
But, because the degree of depth (thickness on the direction of principal axis of drum type weld cap holder 31) of the accommodation hole for hold electrodes contact is identical without exception, therefore when the electrode contact after finishing also will be in short-term than the degree of depth of accommodation hole, also be in the electrode contact of using state not in accommodation hole, can not abut with stopper section and pass through from conveying end, thus the electrode contact after finishing can not utilize again.On the contrary, if be the degree of depth that benchmark sets accommodation hole with the electrode contact extremely close to the length using boundary, for the electrode contact of new product or the longer electrode contact of length, the area exposed from accommodation hole increases, namely the area kept by accommodation hole of electrode contact reduces, therefore when the electrode contact of conveying end place new product or the longer electrode contact of length abut with stopper section, there will be electrode contact from accommodation hole floats, tilt, dropping etc. keeps unstable phenomenon.Its result, causes the action of electrode contact Storage Box to stop.
In addition, when loading electrode contact in the electrode contact Storage Box of patent document 2 and patent document 3, needing the lid of Storage Box body (is top cover 81 in patent document 2; Be Storage Box lid 4 in patent document 3) unload, thus the problem that the filling process having electrode contact is time-consuming.Although do not unload lower cover and from conveying end filling also passable, unexpectedly become by the irrational work pointed.In addition, when have as patent document 2 hold passage time, holding in passage 90 when being mixed into foreign matter, just cannot find foreign matter if do not unloaded top cover 81, the fault (trouble) such as therefore easily can cause the inclination of electrode contact, cannot move.
And then the installation to fixture of electrode contact Storage Box is: in patent document 2, is undertaken by the mount pin 86 of assembling fixture 85; In patent document 3, carried out being articulated in hinge support chip 47 with acquisition opening 40 position in opposite directions by Storage Box lid 4.But, as being subject to external force when elongate portion enters, then mount pin 86 or hinge support chip 47 act on the position of excessive stress and conveying end (obtaining opening 40) from the aligned position change preset, can occur during the replacing of electrode contact 70 can not the problem of normal operation.
