Description

Technical Field

[0001] The utility model relates to the technical field of valve body processing, in particular to a valve body processing positioning device. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff and regulation. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0003] When processing the valve body, the workpiece needs to be clamped and fixed first. At the same time, the machine tool is generally fixed in one position. In order to cooperate with the tool head of the processing machine tool to perform fixed-point processing on the workpiece, this also requires the workpiece to have a certain position adjustment ability while being clamped, so that the position of the workpiece to be processed can be accurately aligned with the machine tool tool head, so a positioning device is required.

[0004] Therefore, the utility model provides a valve body processing positioning device to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a valve body processing positioning device that solves the above-mentioned problems. The workpiece to be processed is first placed on one side of the abutment plate, and then the movable end is extended to one side by starting the two-way hydraulic rod, thereby causing the first connecting rod to rotate, and with the cooperation of the second connecting rod, the rubber clamp is moved close to the workpiece, and the workpiece can be clamped and fixed in cooperation with the abutment plate. The rubber clamp can prevent direct contact between hard metal objects, which will cause dents on the workpiece and has a certain buffering effect; the servo motor is started to drive the active pulley and the first screw to rotate, and the first screw will cause the first mounting plate to move in the longitudinal direction. At the same time, the active pulley will drive the driven pulley through the transmission belt. When the second screw is rotated, the driven pulley will drive the second screw to rotate, thereby prompting the second mounting plate to move longitudinally synchronously with the first mounting plate. The sliding rod can limit the second mounting plate through the limit block to prevent it from rotating. The cylinder can be started and the assembly block can be pushed to move laterally through the extension rod. The roller can play a supporting role and reduce some friction resistance. In this way, the position can be adjusted both longitudinally and laterally. Just like the coordinate system, the workpiece can be positioned more accurately so that it can be aligned with the tool head of the machine tool for processing. The reinforcement block can support the active end of the extension rod and the cylinder to make the movement more stable. The brush can clean out the debris generated during processing from the groove of the supporting base block.
