Problems solved by technology

In practical applications, joint bearings interfere with the arm. One is that the joint bearings are often corrected, which affects normal production. The other is that the joint bearings are easily damaged, causing danger.
[0003]At present, some robot manufacturers in the world, such as FANUC robot manufacturers, adopt a structure that is a copper sleeve or cast iron part connecting the balancer shaft and the arm, which cannot rotate, which requires The balancer, boom, and swivel seat have high processing precision and high installation precision, so as not to damage the parts, but the production cost is also very high
That is, there are the following technical problems in the prior art: the joint bearing interferes with the boom and the balancer is difficult to install and the cost is high

Embodiment Construction

[0031] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0032] The core of this embodiment is to fix the balancer guide sleeve (7) after the joint bearing (3) is automatically aligned, and prevent the balancer shaft (10) from rotating through the anti-rotation pin (8).

[0033] In actual construction, the joint bearing (3) is installed on the balancer shaft (10), and the joint bearing (3) is connected with the boom (1) through the balancer shaft (2). When the boom (1) rotates, the balancer is pulled The shaft (10) slides back and forth in the balancer guide sleeve (7), and the support point of the balancer (4) is on the swivel seat (5), which requires that the installation surfaces of the boom, the swivel seat, and the balancer are uniformly parallel In-plane, but it is difficult to achieve during processing, there will always be errors, and ...

Abstract

The invention relates to a balancer of a welding robot, and a construction method thereof; the balancer comprises a balancer shaft (10), a balancer guide bushing (7), a fixed pin and a joint bearing (3); the shaft end of the balancer shaft (10) is connected with the joint bearing (3); the balancer shaft (10) can be arranged in the balancer guide bushing (7) in a sliding way; and the fixed pin is inlaid on the balancer guide bushing (7) and can slide relative to the balancer shaft (10).

Description

technical field [0001] The invention relates to the safe use of a robot mechanism, belongs to the field of industrial robots, and in particular relates to a balancer of a welding robot and a composition method thereof. Background technique [0002] The robot balancer is installed on the second axis of the robot, and the load on the second axis motor can be reduced through the expansion and contraction of the spring. It is required that the mounting surfaces of the robot's boom, swivel base, and balancer must be installed in parallel planes, and the machining precision of each part is very high, and the manufacturing cost is very high. Joint bearings are used for the connection between the swivel base and the boom, and the swing angle of the joint bearings is ±7°. In practical applications, joint bearings interfere with the big arm. One is that the joint bearings are often corrected, which affects normal production, and the other is that the joint bearings are easily damaged...
