Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
A kind of coping device bindiny mechanism, is mainly used on white body welding production line, for the reconditioning operation of welding gun A；
The bindiny mechanism is generally located below welding gun A combined with Figure 1 and Figure 2, by the way that the coping device being installed on it is moved upward to weldering
Two electrode cap positions of rifle A, using the rotating blade of coping device to electrode cap reconditioning, to realize electrode cap in the certain weldering of work
Maintenance after point.
Above-mentioned coping device bindiny mechanism includes support 3, and support 3 is fixed on the bottom plate A2 for being used to support welding gun A；Support 3
On be provided with telescopic cylinder 4 and swing arm 1,1 one end of swing arm is rotatably connected on support 3,1 other end of swing arm be installation coping device
Free end；Cylinder block 5 is arranged for driving swing arm 1 to rotate in telescopic cylinder 4 on support 3, the cylinder body 4a of telescopic cylinder 4, which is rotated, to be connected
It connects on cylinder block 5, the piston rod 4b of telescopic cylinder 4 stretches to swing arm 1, and hinged with the hinged seat 1a in swing arm 1.In swing arm 1
The position of hinged seat 1a preferably adjacent to swing arm 1 rotate point so that telescopic cylinder 4 with lesser stroke can obtain swing arm 1 compared with
Big rotational angle.Crumb loading device 2 is further fixed in swing arm 1, crumb loading device 2 is cylindrical container, is located at below coping device, and by leading
It considers pipe B1 to be worth doing and collects the reconditioning bits that coping device generates；The one end crumb guiding pipe B1 is fixed on the circumferential direction of coping device rotating blade, and the other end connects
It connects in 2 upper end of crumb loading device.In order to avoid omission reconditioning bits pollution telescopic cylinder 4 piston rod 4b, in conjunction with Fig. 3 it is found that
Dust cover 7 is set outside piston rod 4b, and dust cover 7 is fabricated from a flexible material, and one end of which is fixed on the fixations of the front end piston rod 4b
On nut, the other end is fixed on the cylinder body 4a front end face of telescopic cylinder 4；When in piston rod 4b retraction cylinder body 4a, dust cover 7 is then
It is compressed, when piston rod 4b stretches out, dust cover 7 is then unfolded, and such setting avoids reconditioning bits from falling into the surface piston rod 4b, influences it
Movement.
In conjunction with Fig. 3 and Fig. 4, the upper pendulum of swing arm 1 and bottom position pass through the first limit plate that 1 two sides of swing arm are arranged in respectively
12 and second limit plate 8 limit, the first limit plate 12 is fixed on support 3 close to 5 side of cylinder block, by the first mounting base 11
On, the surface of 12 opposed swing arms 1 of the first limit plate is provided with the first spacing block set 12a；It is corresponding, opposite first limit of swing arm 1
12 surface of plate is provided with closure limit plate 13, is closed installation closure spacing block set 13a on limit plate 13；It specifically sees Fig. 4, works as swing arm
When 1 rotation to vertical direction is in working condition, it is closed on the closure spacing block set 13a and the first limit plate 12 on limit plate 13
First spacing block set 12a is contradicted；Meanwhile the first elastic buffer 12b, the first elastic buffer being installed on the first limit plate 12
Device 12b is towards closure limit plate 13, and the first contact closure limit before closure spacing block set 13a and the first spacing block set 12a is contradicted
Position plate 13 generates significant shock and noise to play buffer function when avoiding hitting.
Similarly, Fig. 3 is specifically seen, the second limit plate 8 is fixed on support 3 by the second mounting base 10, on the second limit plate 8
It is provided with the second spacing block set 8a and the second elastic buffer 8b, the corresponding setting in swing arm 1 opens limit plate 9 and opens limit
Position convex block 9a opens spacing block set 9a and contradicts the second spacing block set 8a in the inclination opening state as shown in Figure 3 of swing arm 1, and
It is offseted by the second elastic buffer 8b with the second limit plate 8 before the two contradicts, realizes buffer function.
Since the first limit plate 12 is located between the rotation seat 14 and cylinder block 5 of swing arm 1, telescopic cylinder 4 in order to prevent
Piston rod 4b movement interferes with the first limit plate 12, and 5 height of cylinder block is preferably higher than the first limit plate 12, and the cylinder of telescopic cylinder 4
It is rotatably connected on cylinder block 5 in the middle part of body 4a, to reduce the amplitude of fluctuation of cylinder body 4a.
In conjunction with Fig. 5 and Fig. 6, the rotation seat 14 of swing arm 1 is fixed on support 3, and shaft 15 is laterally fixed on rotation seat 14,
It is arranged with axle sleeve 17 in shaft 15, rotary connection plate 18 is fixed on axle sleeve 17, the end of swing arm 1 is connected by fastener to rotate
Connecting plate 18；In order to reduce the frictional resistance of axle sleeve 17 Yu shaft 15, copper sheathing 19, copper sheathing are set between axle sleeve 17 and shaft 15
19 be a pair, and baffle ring 20 is arranged between copper sheathing 19；Thrust washer is provided between 14 inner wall of 17 both ends of the surface of axle sleeve and rotation seat
16, thrust washer 16 is carbon materials matter, to reduce the frictional force between axle sleeve 17.
In conjunction with Fig. 1-4, two electrode caps of welding gun A are separately fixed on a pair of of cantilever A3, a cantilever A3 and lower section
Support base A4 is fixed, another cantilever A3 and support base A4 are rotatablely connected, and the lower end cantilever A3 of the flexible connection is connected with folding
Cylinder A1, by the flexible two electrode cap divisions to control welding gun A for opening and closing cylinder A1；When welding gun A needs coping device, folding
Cylinder A1 controls two electrode caps and separates, and enters convenient for the rotating blade of coping device；The piston rod 4b of telescopic cylinder 4 is shunk, living
Stopper rod 4b drives swing arm 1 to be rotated up to operating position, and the first elastic buffer 12b is preparatory when swing arm 1 is close to operating position
Buffering, then the closure spacing block set 13a in swing arm 1 and the first positive stop lug boss contradict, it is ensured that coping device and welding gun A are precisely contacted
Carry out reconditioning；When coping device Butt welding gun A carries out reconditioning, reconditioning bits enter crumb loading device 2 by the crumb guiding pipe B1 on coping device
In, due to being cased with dust cover 7 outside the piston rod 4b of telescopic cylinder 4, avoid the reconditioning bits pollution piston for not entering crumb loading device 2
Bar 4b；After the completion of reconditioning, the piston rod 4b of telescopic cylinder 4 stretches out, and swing arm 1 is driven to leave welding gun A, when the rotation of swing arm 1 is to connecing
When nearly downlink limit point, the second elastic buffer 8b and deceleration buffer, the second last spacing block set 8a and unlatching limit convex are contradicted
Block 9a is contradicted, and swing arm 1 reaches off-position.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
