Automatic C-shaped-arm bearing laminating device

Abstract

The invention discloses an automatic C-shaped-arm bearing laminating device. The automatic C-shaped-arm bearing laminating device comprises a straight arm and a C arm, wherein the straight arm is connected with the C arm in a non-fixed manner, and multiple sets of straight-arm upper roller rods are installed at the bottom of the straight arm. A straight-arm lower roller rod is installed on the outer side of each straight-arm upper roller rod, a straight-arm middle roller rod is installed on the inner side of each straight-arm lower roller rod, and a first deep groove ball bearing is installedon the outer side of each straight-arm middle roller rod. According to the automatic C-shaped-arm bearing laminating device, by means of the straight-arm middle connecting rod, the straight-arm lowerconnecting rod and the attached deep groove ball bearings, it can be guaranteed that 20 deep groove ball bearings are used for bearing when the C arm slides up and down, 8 deep groove ball bearings are used for bearing when the C arm slides left and right, and therefore the weights of the C arm, a ball pipe and a detector can be well dispersed on the whole straight-arm surface at each sliding position; and each deep groove ball bearing can do minor movement, assembly is convenient to achieve, and the C arm can be installed more smoothly in the installation process.

Description

technical field [0001] The invention relates to a sliding connection device for a C-shaped arm and a straight arm, in particular to an automatic bonding device for a C-shaped arm bearing. Background technique [0002] In the existing sliding connection between the C-arm and the straight arm, the sliding connection is generally completed by using bearing housings with deep groove ball bearings, and usually two sets of bearing housings are respectively located at the upper and lower ends of the straight arm arc. The upper and lower sliding bearings are responsible for carrying and making the C-arm slide in the vertical state of the straight arm, and the left and right sliding bearings are responsible for carrying and making the C-arm slide in the horizontal state of the straight arm. The existing sliding connection method only has four deep groove ball bearings for up and down sliding and left and right sliding. The weight is inconsistent; there are only four deep groove ball...

AI Technical Summary

Problems solved by technology

The existing sliding connection method only has four deep groove ball bearings for up and down sliding and left and right sliding. The weight is inconsistent; there are only four deep groove ball bearings in each direction as the sliding fulcrum, resulting in unsmooth sliding, and it is laborious to slide within a certain range; the bearing housing is processed and installed with high precision, and if it is not assembled properly, the C arm will not slide smoothly. Smooth; bumps during transportation will cause looseness, and deep groove ball bearings cannot self-adjust, which will cause the C-arm to slide unsmoothly
