Description
Technical field
The present invention relates to field of welding devices, be specifically related to the crashproof arm of a kind of welding robot.
Background technology
Along with the degree of automation improves gradually, welding robot obtains extensive utilization in engineering machinery field.Welding robot belongs to precision equipment, and there is important impact each junction of fuselage for its welding precision.
The existing welding robot overwhelming majority is all carry out programming Control by programmable device to not only motor; and be much all program curing; once any one position of welding robot fuselage is clashed into; program control system all can produce protective effect to power part; but be important frame for movement really cannot be protected; shock can cause the junction of fuselage to be subject to larger wearing and tearing, thus welding robot welding precision can be caused inaccurate.In enterprise, the arm of welding robot often can collide due to a variety of causes, as the collision of arm and workpiece, and the interference and collision of arm and frame or the interference of moving due to robot itself and the collision that causes.After colliding, welding robot just needs again to debug, and will certainly waste a large amount of time like this, even the welding robot situation that also can arm be caused to scrap because impact is excessive.And frequent collision also can cause the arm shortening in service life of welding robot.
Summary of the invention
The object of the present invention is to provide the crashproof arm of a kind of welding robot, make the arm of welding machine robot have certain impact resistant capability, arm service life can be extended.
For achieving the above object, base case of the present invention is: the crashproof arm of a kind of welding robot, comprise the large armed lever that upper end connects welding machine robot fuselage main body, for little armed lever and the extension spring of connecting welding robot welding parts, the lower end of large armed lever is arranged with two pieces of support plate bodys in parallel, two pieces of support plate bodys are respectively arranged with the riveted holes in axisymmetrical, the body of little armed lever is provided with vertical groove, the both sides of groove are rotationally connected by the riveted holes on support plate body and support plate body, between the middle part that extension spring is fixedly installed on large armed lever and groove, the lower end of little armed lever is provided with a chute fixed for welding assembly.
Operation principle and the advantage of this programme are: the both sides of little armed lever upper groove are rotationally connected by the riveted holes on support plate body and support plate body, and little armed lever rotates clockwise along large armed lever, and the cushion stroke of this rotation just in order to provide little armed lever to clash into.The object little armed lever being arranged groove is that groove is that extension spring provides certain space, can prevent extension spring and little armed lever from producing movement interference like this.When little armed lever is subject to clashing into; the elastic force that little armed lever overcomes extension spring can rotate clockwise along large armed lever, but after having clashed into, extension spring can be returned to initial position; namely absorb the impact on little armed lever by extension spring, thus protect little armed lever and large armed lever.
This crashproof arm had both maintained the rigidity of welding robot operation, again for the arm of welding robot provides certain impact resistant capability.After shock occurs, the arm of welding robot can also be returned to original state by extension spring, does not need technical staff to debug program again, has saved the working time to a certain extent, has improve operating efficiency.And the arm machinery with certain impact resistant capability also can be extended service life.
Prioritization scheme one: based on the preferred version of scheme, two pieces of support plate bodys are respectively arranged with the arc chute in axisymmetrical, the both sides of groove are respectively arranged with the limited post corresponding respectively with two pieces of support plate bodys, and limited post is connected in arc chute.The object arranging arc chute is that namely arc chute can not produce the motion of little armed lever and interferes, and can limit again the movement locus of little armed lever, maintain the bonding accuracy of welding robot to a certain extent.
Preferred version two: the preferably preferred version of, the middle part of large armed lever is also provided with a vertical screwed hole, screwed hole inward turning is screwed with bolt, the lower end of bolt is provided with a regulating sleeve, the lower end of regulating sleeve and bolt is rotationally connected, and extension spring is fixedly installed between regulating sleeve and groove.Be fixedly installed on by extension spring between regulating sleeve and groove, by being arranged on the large elastic force that just can regulate extension spring than the bolt at middle part, the operation facilitating technical staff uses, for the adjustment and installation of welding machine robot is provided convenience.
Preferred version three: the preferably preferred version of two, is also provided with two metallic channels in groove.In groove, arrange metallic channel, metallic channel is in order to erecting and welding parts, and groove prevents welding spark or Mars to be splashed on welding assembly to a certain extent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crashproof arm embodiment of a kind of welding robot of the present invention;
Fig. 2 is the arc chute schematic diagram of the crashproof arm embodiment of a kind of welding robot of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: large armed lever 1, bolt 2, regulating sleeve 3, extension spring 4, little armed lever 5, support plate body 11, arc chute 12, groove 51, metallic channel 52, chute 53, limited post 54.
