Description
Technical field
The present invention relates to field of welding devices, be specifically related to a kind of welding robot high precision movement device.
Background technology
Welding robot has stabilizes and increases welding quality, raises labour productivity, improves the advantages such as labor strength, and welding robot popularity rate at home improves fast.The rectilinear movement feed control system that existing welding robot is commonly used mainly comprises hydraulic servo control system, the closed loop circuit control system of stepper motor and high precision fine tuning servo-control system, these control systems single have a common shortcoming: that is exactly the precision that the precision of all control system all depends on the drive disk assembly of control system, as the number of teeth, the corner of stepper motor, the minimum control speed etc. of hydraulic cylinder under steady-working state of gear gear.Exactly because and so, for some high-accuracy parts when welding, often need to adopt high-precision welding robot, and this high-precision welding robot also only has and abroad just has, so my domestic enterprise still cannot manufacture some high-accuracy parts now, this problem constrains the development of enterprise greatly.
Summary of the invention
The object of the present invention is to provide a kind of welding robot high precision movement device, welding robot can be made to have higher mobile accuracy.
For achieving the above object, base case of the present invention is: a kind of welding robot high precision movement device, comprise frame, the first hydraulic cylinder be fixedly mounted in frame, the first gripper shoe be fixedly connected with the piston rod of the first hydraulic cylinder, the second gripper shoe be slidably connected with the first gripper shoe and the second hydraulic cylinder be fixedly mounted in the first gripper shoe, the piston rod of the second hydraulic cylinder is fixedly connected with the second gripper shoe, and the first hydraulic cylinder and the second hydraulic cylinder are oppositely arranged and the movement velocity of the first hydraulic cylinder is greater than the movement velocity of the second hydraulic cylinder.
Operation principle and the advantage of this programme are: the movement velocity of the first hydraulic cylinder is greater than the movement velocity of the second hydraulic cylinder.When the first hydraulic cylinder promotes the first gripper shoe to the right, the second hydraulic cylinder promotes the second gripper shoe left, and at this moment the difference of the movement velocity of the first gripper shoe and the second gripper shoe is exactly the movement velocity that welding robot moves right.This kind of set-up mode can realize the higher mobile accuracy of welding robot under the condition not changing existing welding machine robot mobile device precision, is very favorable for most enterprises.This device is easy to realize, even if those skilled in the art also can carry out arranging and safeguarding, very easy to use.
Prioritization scheme one: based on the preferred version of scheme, frame is fixedly installed the first linear slide rail, the first gripper shoe is connected with housing slide by the first linear slide rail.First linear slide rail secures the movement locus of the first gripper shoe, makes the first gripper shoe can do linear slide along frame, is conducive to controlling the second gripper shoe.
Preferred version two: the preferably preferred version of, the first gripper shoe is fixedly installed the second linear slide rail, the second gripper shoe is slidably connected by the second linear slide rail and the first gripper shoe.Second linear slide rail secures the movement locus of the second gripper shoe, and make the second gripper shoe can do linear slide along the first gripper shoe, the movement locus being conducive to butt welding machine device people controls.
Preferred version three: the preferably preferred version of two, the first linear slide rail is parallel to the second linear slide rail.Simple algorithm so just conveniently can be adopted to control the movement velocity of welding robot, make this device be easy to universal inside most enterprises and use.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of a kind of welding robot high precision movement of the present invention device embodiment.
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: frame 1, first hydraulic cylinder 2, first linear slide rail 3, first back-up block 4, second linear slide rail 5, second back-up block 6, second hydraulic cylinder 7, welding robot 8.
Embodiment is substantially as shown in Figure 1: a kind of welding robot high precision movement device, the first gripper shoe comprising the first hydraulic cylinder 2 be fixedly mounted in frame 1, be slidably connected with frame 1, in the present embodiment, frame 1 is fixedly installed the first linear slide rail 3, first gripper shoe to be slidably connected with frame 1 by the first linear slide rail 3.First gripper shoe is fixedly installed on the second linear slide rail 5, second linear slide rail 5 and is installed with the second gripper shoe, welding robot 8 is fixedly mounted in the second gripper shoe.As shown in Figure 1, the piston rod of the first hydraulic cylinder 2 is fixedly connected with the first gripper shoe.Second hydraulic cylinder 7 and the first hydraulic cylinder 2 are oppositely arranged, and the piston rod of the second hydraulic cylinder 7 is fixedly connected with the second gripper shoe, and the second hydraulic cylinder 7 is fixedly mounted in the first gripper shoe.
In the present embodiment, the movement velocity of the first hydraulic cylinder 2 is greater than the movement velocity of the second hydraulic cylinder 7.When the first hydraulic cylinder 2 promotes the first gripper shoe to the right, the second hydraulic cylinder 7 promotes the second gripper shoe left, and at this moment the difference of the movement velocity of the first gripper shoe and the second gripper shoe is exactly the movement velocity that welding robot 8 moves right.
In the present embodiment, the first linear slide rail 3 is parallel to the second linear slide rail 5 and arranges, and so just can conveniently adopt simple algorithm to control the movement velocity of welding robot 8.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
