Abstract
The invention provides a vertical movement device of a truss manipulator. The vertical movement device of the truss manipulator comprises a truss, a cantilever, a travelling mechanism and a transmission mechanism. The truss and the cantilever are connected through the travelling mechanism, the cantilever is of a rectangular tubular structure, the three neighboring side surfaces of the truss are working surfaces, the travelling mechanism comprises linear guide rails or ball screws, and the transmission mechanism comprises racks or lead screws. The vertical movement device of the truss manipulator changes single-surface stress into symmetrical double-surface stress, overcomes the existing defect of uneven stress, reduces damage due to inertia force during rapid movement, enhances integral rigidity and prolongs the service life.
Description
Technical field
The invention belongs to truss robot field, especially relate to a kind of truss robot longitudinal moving device.
Background technology
In the various productions of the present extensive use of truss robot, especially for the welding of main equipment, there is unrivaled advantage.The electric welding machine deadweight of carrying in general truss robot is all heavier, and has high requirement for walking positioning precision.Traditional upper arm structure often, after using a period of time, because unbalance stress there will be distortion, is brought great difficulty to high accuracy walking location.In addition, often repair and waste time and energy, cost is high.
Summary of the invention
The problem to be solved in the present invention be to provide a kind of stressed evenly, truss robot longitudinal moving device that rigidity is strong.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of truss robot longitudinal moving device, comprise truss, upper arm, walking mechanism and transmission mechanism, described truss and upper arm link together by walking mechanism, and described upper arm is rectangular tubular structure; Three sides that described truss is adjacent are working face, and two working faces that are parallel to each other are the first working face and the second working face, with the first working face or the perpendicular working face of the second working face be the 3rd working face; Described walking mechanism comprises line slideway or ball-screw; Described transmission mechanism comprises tooth bar or leading screw.
Further, described line slideway has two groups at least, is fixed in respectively on first working face and the second working face of truss; The slide block matching with described line slideway is fixed in respectively on the inner plane of upper arm.
Further, described ball-screw has two groups at least, is fixed in respectively on first working face and the second working face of truss, and the nut matching with described ball-screw is fixed in respectively on the inner plane of upper arm.
Further, described tooth bar is fixed on the 3rd working face of truss, and the gear being meshed with described tooth bar is fixed on the corresponding inner plane of upper arm.
Further, described leading screw is fixed on the 3rd working face of truss, and the screw in mating connection with described leading screw is fixed on the corresponding inner plane of upper arm.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, by single side face, stressed to change symmetrical two sides into stressed, overcome the shortcoming of original unbalance stress, the damage that the inertia force while having reduced rapid movement brings, strengthen integral rigidity, extended service life.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further elaborated.
As shown in Figure 1, a kind of truss robot longitudinal moving device in the present embodiment, comprises truss 1, upper arm 4, walking mechanism and transmission mechanism, and truss 1 and upper arm 4 link together by walking mechanism, and upper arm 4 is rectangular tubular structure; Three sides that truss 1 is adjacent are working face, and two working faces that are parallel to each other are the first working face and the second working face, with the first working face or the perpendicular working face of the second working face be the 3rd working face; Walking mechanism comprises line slideway 2, and line slideway 2 has two groups, is fixed in respectively on the first working face and the second working face, and the slide block 6 matching with line slideway 2 is fixed in respectively on the inner plane of upper arm 4; Transmission mechanism comprises tooth bar 3, and tooth bar 3 is fixed on the 3rd working face of truss 1, and the gear 5 being meshed with tooth bar 3 is fixed on the corresponding inner plane of upper arm 4.
As shown in Figure 2, original truss robot longitudinal moving device also comprises truss, upper arm, line slideway and tooth bar, two line slideways and tooth bar are all fixed on the same side of upper arm, due to moving component drive is stressed vertically downward structure, stressed all at medial surface, rigidity of support is poor.
Compared with original truss robot longitudinal moving device, clearly, by inner side force dispersion, to both sides, make to support the parts rigidity moving both vertically increases design benefit of the present invention, reduces the damage that inertia force brings in the time of rapid movement; Structure of the present invention is by guide rails assembling in two sides, and mounting seat structure is surrounded whole column vertically downward completely, has strengthened the rigidity of package unit; Overcome the shortcoming of original unbalance stress, increased the integral rigidity of pillar construction in the time of rapid movement, extended service life.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
