Description

Technical Field

[0001] This utility model relates to the technical field of ball valve processing equipment, specifically a positioning device for ball valve processing. Background Technology

[0002] A ball valve consists of a ball, a valve seat, a valve stem, and a housing. The ball controls the flow of the medium by rotating and is widely used in fluid transportation in fields such as water supply and chemical industry. During its production, the valve body must be symmetrical in multiple positions and the alignment of the central axis. If there is any deviation, it will lead to leakage or inaccurate control of the valve body.

[0003] After the ball valve processing equipment has positioned and fixed the shell, it lacks the function of real-time ball valve shell detection. The overall symmetry and central axis alignment of the finished product can only be detected after processing is completed. It is impossible to detect the size and shape problems of the ball valve shell in time during the processing, which indirectly affects the production and processing efficiency.

[0004] To address the aforementioned issues, we have made improvements and proposed a positioning device for ball valve processing. Utility Model Content

[0023] A first bearing seat 10 is fixedly installed on the right middle part of the top surface of the processing table 1 by bolts. An AC motor is fixedly installed on the right top center of the first bearing seat 10 by bolts. The right center of the first positioning fixture 11 is rotatably connected to the left top center of the first bearing seat 10 by bearings. The rotating shaft of the AC motor is fixedly connected to the right center of the first positioning fixture 11.

[0024] An auxiliary slide rail 13 is fixedly installed at the rear end of the left side of the top surface of the processing table 1 by bolts. A connecting loading plate is fixedly installed between the slider of the auxiliary slide rail 13 and the slider of the third electric guide rail 12 by bolts.

[0025] The first positioning fixture 11 includes a slide groove, a guide rail is fixedly installed inside the slide groove, and sliders are slidably installed at both the front and rear ends of the guide rail.

A DC motor drives a bidirectional threaded rod to rotate, which in turn moves the two positioning blocks to change their spacing for fixation. The position of the second bearing seat 14 can be adjusted according to the length of the ball valve. The movement of the second bearing seat 14 and its mounted second positioning fixture 15 is controlled by the third electric guide rail 12. After fixing the ball valve housing, some areas that need to be processed can be selected. The horizontal and vertical movement of the spring telescopic rod 8, which is equipped with rollers 9, is controlled by the first electric guide rail 3 and the second electric guide rail 5, so that the rollers 9 are pressed against the surface of the ball valve housing. Then, the AC motor is started to drive the first positioning fixture 11, the second positioning fixture 15, and the fixed ball valve housing to rotate. The presence of asymmetry or misalignment of the central axis is monitored by detecting changes in the value of the pressure sensor 7.
