Description
Technical field
The utility model relates to tooling and fixture technical field, and in particular to a kind of robot Tube-sheet Welding frock clamp.
Background technique
Currently, with the rapid development of China's equipment manufacture, it is also higher and higher to welded welding equipment required precision,
Requirement to automation and intelligentification is higher and higher.Tube sheet junction is welded using robot arm for currently used,
The accurate positioning of tube sheet is always a problem, should accurate positioning, do not interfere the operating of mechanical arm again, with improve welding
Production efficiency.Existing way is first manually positioned to tube sheet when carrying out Tube-sheet Welding, and welding is then implemented, not only numb
Tired, positional accuracy is not also high.With welding robot man-based development and popularization, the problem of robot Tube-sheet Welding positions, is more prominent
It is aobvious.In addition, current general welding fixture fixture can not arbitrarily adjust Tube-sheet Welding position, the technology for being difficult to meet welding is wanted
It asks, and welding equipment is time-consuming and laborious.
Summary of the invention
The problem of in view of the above welding process, problem when being welded in particular by welding robot, this
The purpose of utility model be to provide a kind of flexible adjustment, it is easy to use, can be realized tube sheet positioning and simple and reliable tube sheet is fixed
Position welding tool setup.
In order to achieve the above objectives, technical solution used by the utility model is as follows:
A kind of tube sheet positioning welding frock clamp of flexible adjustment, upright bar, top including bottom belt magnechuck seat are
Screw rod and loop bar that lower part is sleeved on outside upright bar, are fitted in loop bar upper screw at the lateral locking nut for being set to loop bar lower part
On swivel nut, radially distributed three support arms for being welded in swivel nut outer wall, the end nut for being set in screw tip, in radiation
Shape is evenly distributed with and passes through three two link-type clamp arm that hinged shaft is articulated on end nut, is articulated with the arc of clamp arm front end by hinged shaft
Face pressure disk, the front end of three support arms are hingedly connected in the preceding end arms of three two link-type clamp arm.
The upright bar of the utility model is screwed in the center screw of magnechuck seat by the screw rod of its bottom.
The upright bar of the utility model and loop bar can be inserted into steel pipe, and bottom chuck seat, which can be adsorbed on, is placed in steel pipe bottom
On steel plate, steel pipe is clamped by the cambered surface platen of support arm moving up and down and telescopic three clamp arm and its front end, is made
The steel plate position for obtaining steel pipe and its bottom is fixed, and welding robot mechanical arm is facilitated to carry out boxing seam welding to tube sheet junction,
Break the limitation that the prior art needs first to be positioned manually when carrying out Tube-sheet Welding.The clamping range of fixture is adjustable, convenient for pair
The weldment of different-diameter is clamped, flexible to operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is schematic diagram when the utility model is used for Tube-sheet Welding.
Specific embodiment
As shown in Figure 1 and Figure 2, the tube sheet positioning welding frock clamp of a kind of flexible adjustment, including bottom belt magnechuck seat
1 upright bar 2, top be screw rod and loop bar 4 that lower part is sleeved on outside upright bar 2, the lateral locking nut 3 for being set to loop bar lower part,
The swivel nut 5 that is fitted in loop bar upper screw, is set in screw rod at radially distributed three support arms 6 for being welded in swivel nut outer wall
The end nut 9 at top, radially distributed and three two link-type clamp arm 7, logical for being articulated with by hinged shaft on end nut
The cambered surface platen 8 that hinged shaft is articulated with clamp arm front end is crossed, the front end of three support arms 6 is hingedly connected to three two link-type clamp arm
On 7 preceding end arms 7a.It can be freely rotated along joint shaft 10 between two joint arms of two link-type clamp arm 7.
Magnechuck seat 1 and upright bar 2 can make integrally, can also be inhaled by being threaded into electromagnetism in the processing of 2 bottom of upright bar
In the screw hole of disk seat center processing.The Primary Location of weldment can be achieved in magnechuck seat.Loop bar can be moved up and down along upright bar to adjust
The height of a whole set of bar adapts to the welding of different height.Upright bar 2 and loop bar 4 pass through 3 locking positioning of locking nut.Swivel nut 5 can be along set
The rotation of bar upper screw section, the height of support arm 6 is adjusted with realization, and the clamped height of clamp arm is adjusted with this.End nut 9 can edge
Screw rod rotation adjusts clamp arm movement, adjusts arc platen 8 and clamps weldment.
As shown in Fig. 2, the working method of the utility model is as follows:
Upright bar 2 and loop bar 4 are inserted into steel pipe 11, the stabilization of bottom chuck seat 1 is adsorbed on the steel plate for being placed in steel pipe bottom
On 12, steel pipe is handled by the cambered surface platen stabilization clamp of support arm moving up and down and telescopic three clamp arm and its front end
12, so that steel pipe 11 and its 12 position of the steel plate of bottom are fixed, that is, realize positioning, subsequent welding robot mechanical arm
Boxing seam welding is carried out to the tube sheet junction of steel pipe 11 and steel plate 12.
