Specific implementation mode
For it is relatively intuitive, be fully understood by technical scheme of the present invention, now just combine attached drawing of the present invention to carry out non-limiting Feature description it is as follows:
As shown in figs 1 to 6, it moves back bar Nut riveter automatically, including riveting gun seat 1, nut tune in 1 front end of riveting gun seat is set Mechanism 2, two handles 3 mounted on 1 rear end both sides of riveting gun seat are saved, nut adjusting mechanism 2 is including adjusting sleeve 21 and axially Riveting nut bar 22 on adjusting sleeve 21 is set, a pull rod 4 is equipped in riveting gun seat 1, the top of two handles 3 connects by one respectively Bar 5 is connect with the draw-bar seat 6 being sleeved on outside pull rod 4, it further includes moving back linkage 7;It includes being mounted on draw-bar seat 6 to move back linkage 7 The planetary transmission 71 of bottom end is arranged in 71 bottom end of planetary transmission and the internal housing 72 that screw rod 721 is housed and passes through A connecting seat 10 is arranged exits connecting rod 73 in 72 top both sides of housing, and screw rod 721 coordinates with planetary transmission 71, the company of exiting The bottom end of bar 73 is connected with the bottom end of handle.
The mode that the bottom end of adjusting sleeve 21 is connected through a screw thread is connect with the top of riveting gun seat 1, the top of riveting nut bar 22 End, which is stretched out, adjusts sleeve 21, and nut adjusting mechanism 2 further includes mounted on the fixation sliding sleeve 23 on 4 top of pull rod and setting in fixation The top of the connection sliding sleeve 24 on 23 top of sliding sleeve, connection sliding sleeve 24 is connect with the bottom end of riveting nut bar 22, is fixed sliding sleeve 23 and is connected Sliding sleeve 24 is connect to be accommodated in adjusting sleeve 21.
The bottom end of two handles 3 is equipped with for anti-skidding handle sleeve 8, and the top of handle 3 and riveting gun seat 1 are hinged, connecting rod 5 One end and the top of handle 3 are hinged, and the other end is hinged with draw-bar seat 6;The both ends of connecting seat 10 are respectively articulated with one and exit connecting rod 73 And it exits the bottom end of connecting rod 73 and is hinged with the bottom end of handle 3.
A positioning block 9 is equipped in connecting seat 10, screw rod 721 passes through locating piece 9 and turns with the top of planetary transmission 71 Dynamic cooperation, the top and the bottom end of pull rod 4 of planetary transmission 71 are rotatably assorted.Locating piece 9 can play setting screw bar 721 first Effect.
The top of locating piece 9 is evenly equipped with multiple convex blocks 16, and the quantity of convex block 16 is four, and 16 one end of each convex block is high, separately One end is low, and when two handles 3 are opened, screw rod 721 can rotate, and when handle 3 is closed, convex block 16 keeps off screw rod 721 Firmly, screw rod 721 is made not rotate.
Connecting rod 73 is exited to be accommodated in handle 3 in the torsional spring 19 for exiting 73 bottom end of connecting rod by being arranged.Exit connecting rod 73 By the way of built-in, space is saved.
There is a rectangular block 15, the top of connection sliding sleeve 24 to be equipped with two blocks 11, two blocks 11 for the bottom end of riveting nut bar 22 Between be formed with a jack 12 being inserted into for rectangular block 15;It is respectively formed between the bottom end of two blocks 11 and the inner wall for connecting sliding sleeve 24 There are the card slot 13 being caught in for 15 end of rectangular block, and the bottom other side of the bottom side of a block 11 and another block 11 Equipped with the blend stop 14 for blocking 15 end of rectangular block;The top of fixed sliding sleeve 23 is inserted with a spring 17, the top of spring 17 It is pressed with a pressing plate 18, the bottom of rectangular block 15 is pressed in 18 top of pressing plate.When installing riveting nut bar 22, a hand pinches riveting nut bar Rectangular block 15 is caught in jack 12 by 22 tops, is then firmly pressed down riveting nut bar 22, pressing plate 18 moves down, then by riveting Nut pole 22 rotates clockwise 90 degree to being blocked to by blend stop 14, and the end of rectangular block 15 has slid into card slot 13 at this time, then Riveting nut bar 22 is unclamped, then so that pressing plate 18 is moved up by the elastic force of spring 17 and withstands rectangular block 15 so that riveting nut bar 22 It installs;Similarly, the dismounting mode of riveting nut bar 22 and mounting means are exactly the opposite, so the present invention has dismounting riveting nut The convenient advantage of bar 22.
The present invention use process is as follows:
Riveting process:Both hands hold handle 3, and handle 3 is closed.Screw rod 721 does not turn at this time, and pull rod 4 is in handle 3 and even It is moved backward under the action of bar 5, by nut riveting on workpiece.
Move back bar process:Both hands hold handle 3, and handle 3 is opened.Screw rod 721 revolves under the action of connecting seat 10 at this time Turn, then screw rod 721 drives planetary transmission 71 to work, and then planetary transmission 71 drives pull rod 4 to rotate again, and pull rod 4 is again Riveting nut bar 22 is driven to rotate, last riveting nut bar 22 is exited from nut.
Provided by the present invention to move back bar Nut riveter automatically, when opening handle 3, control screw rod 721 rotates, and passes through planet Gearbox 71 drives pull rod 4 to rotate, and finally riveting nut bar 22 is driven to exit nut, the setting of planetary transmission 71 enables to people Made with a smaller power riveting nut bar 22 generate a larger rotary force, to enable riveting nut bar 22 quickly, Nut is effectively exited, avoids and occurs moving back the case where bar can not move back, and the length of screw rod 721 can also be reduced, facilitate People use.
Certainly, the above is merely preferred embodiments of the present invention, therefore, it does not limit the scope of the claims of the present invention, all fortune With simply modification and the equivalent structure variation for it of description of the invention and schema content institute, it should all similarly be contained in the special of the present invention Within sharp protection domain.
