Abstract
The utility model discloses an automatic pitch adjustable rotary arm frame of a welding robot. The automatic pitch adjustable rotary arm frame of the welding robot comprises a vertical arm frame, a cross arm frame and a rotary shaft, and a round hole is formed in the vertical arm frame. The rotary shaft penetrates through the round hole of the vertical arm frame and is fixedly connected with the cross arm frame, and the rotary shaft controls rotation and stopping of the rotary shaft by a rotary driving device. The automatic pitch adjustable rotary arm frame of the welding robot can complete accurate adjustment of the distance between the cross arm frame and an applicable platform, solves the problems that manpower adjustment precision is quite low, positioning and repeated positioning precision is high and time is short. Adjustment process is stable so that equipment which is installed on an arm frame can normally operate, and working efficiency is improved by a large margin.

Boom type (or claiming arm type) robot is a present most widely used class welding robot, described boom type robot comprises the jib equipment that interconnective more piece jib forms, as shown in Figure 1, vertically jib and horizontal jib 2 are in 90 degree settings, with a mechanical clamp two joint jibs are fixed together, when needs adjust the top laterally jib 2 apart from usage platform apart from the time, need loosening mechanical clamp regulate its relatively vertically installation site of jib.
At present, this kind jib equipment is widely used in (or other objects) is carried out three dimensions when welding, body surface is carried out single-degree-of-freedom or the multiple degrees of freedom location of space one dimension or various dimensions, and other similar work, during use, carry out space orientation according to welding requirements Butt welding gun (spray gun).When boom type (or claim arm type) robot is used for this or similar occasion, need welding gun (spray gun) to carry out fine adjustment and maintenance with respect to the distance of soldered object, its frame for movement and control had higher requirement, especially need to control accurately position and the direction at a specified point place on its jib, yet existing jib has following defective:
Operating process is complicated;
Positioning accuracy is poor, can't satisfy the demand of hi-Fix;
Repetitive positioning accuracy is poor, the working condition of the high accuracy of can't satisfying the demand resetting;
In the operating process, may cause the jib bumpy motion, and then impact is installed in other equipment operations on the jib.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model be to provide a kind of simple to operate rapidly, registration, high efficiency and stable welding robot automatic distance-adjusting rotation jib.
The technical solution of the utility model is achieved in that
A kind of welding robot automatic distance-adjusting rotation jib, comprise vertical jib, horizontal jib and a rotating shaft, have a circular hole on the described vertical jib, the circular hole that described rotating shaft passes on the described vertical jib is fixedly connected with described horizontal jib, and described rotating shaft is controlled its rotation by a rotating driving device and stopped.
Above-mentioned welding robot automatic distance-adjusting rotation jib, described rotating driving device comprises a piezoelectric motor and controller, described piezoelectric motor is connected with controller.
Above-mentioned welding robot automatic distance-adjusting rotation jib, described rotating driving device comprises a hydraulic motor and controller, described hydraulic motor is connected with controller.
Above-mentioned welding robot automatic distance-adjusting rotation jib, described controller is the PLC controller.
Above-mentioned welding robot automatic distance-adjusting rotation jib also comprises a retractor device, and described retractor device is arranged on the bottom of described vertical jib, and described retractor device is controlled rising and the decline of described vertical jib.
Above-mentioned welding robot automatic distance-adjusting rotation jib, described retractor device is an electric pushrod, the axial identical and concentric of the push rod of described electric pushrod and described vertical jib, described push rod is fixedly connected with described vertical jib bottom.
Above-mentioned welding robot automatic distance-adjusting rotation jib, the motor of described electric pushrod and described controller link together.
Above-mentioned welding robot automatic distance-adjusting rotation jib also comprises usage platform, and the motor of described electric pushrod is fixed on the described usage platform.
The beneficial effects of the utility model are: a kind of welding robot automatic distance-adjusting rotation jib can be finished the fine adjustment of distance between the applicable platform of horizontal jib distance, avoided the manual adjustment jib apart from the time many weak points such as the degree of regulation that can occur is too low, realized quick adjustment, simple to operate, adjustment process steadily and location and repetitive positioning accuracy high, significantly improved operating efficiency, location and repetitive positioning accuracy height and the time compole short, the steady so that various device of installing at jib of adjustment process can move normally.
Description of drawings
Fig. 1 is existing robots arm's shelf structure schematic diagram,
Fig. 2 is the structural representation of the utility model welding robot automatic distance-adjusting rotation jib.
Among the figure: the vertical jib of 1-, the horizontal jib of 2-, 3-controller, 4-electric pushrod, 5-piezoelectric motor, 6-usage platform.
The specific embodiment
By reference to the accompanying drawings the utility model is described further:
As shown in Figure 2, a kind of welding robot automatic distance-adjusting rotation jib, comprise vertical jib 1, horizontal jib 2 and a rotating shaft, have a circular hole on the described vertical jib 1, the circular hole that described rotating shaft passes on the described vertical jib 1 is fixedly connected with described horizontal jib 2, and described rotating shaft is controlled its rotation by a rotating driving device and stopped.
Described rotating driving device comprises a piezoelectric motor 5 and controller 3, and described piezoelectric motor 5 is connected with controller 3, and described controller 3 is the PLC controller.
Also comprise a retractor device, described retractor device is arranged on the bottom of described vertical jib 1, described retractor device is controlled rising and the decline of described vertical jib 1, described retractor device is an electric pushrod, the motor of described electric pushrod 4 and described controller 3 link together, the axial identical and concentric of the push rod of described electric pushrod 5 and described vertical jib 1, described push rod is fixedly connected with described vertical jib bottom.
Also comprise usage platform 6, the motor of described electric pushrod 4 is fixed on the described usage platform 6.
The course of work of welding robot automatic distance-adjusting rotation jib:
When needing welding, welding gun is installed in end at horizontal jib 2, starting PLC controller driving electric pushrod 4 makes vertical jib 1 carry out rough height adjusting, then rotate and then drive horizontal jib 2 by PLC controller control piezoelectric motor 5 and swing, the further adjusting on the fine height, stop swinging after swinging to correct position, adjustment process does not need to become flexible mechanical clamp again, so that operation becomes simple, adjustment process is controlled so that positioning accuracy and repetitive positioning accuracy are quite high by the PLC controller, by electric pushrod 4 and piezoelectric motor 5 regulate on horizontal jib 2 ends welding gun apart from usage platform 6 apart from the time the disturbance of the loosening mechanical clamp of disturbance when regulating horizontal jib 2 very little, therefore can guarantee that the various device that is installed on the horizontal jib 2 can normally move.
