Description

Technical Field

[0001] The utility model belongs to the technical field of valve processing equipment, and in particular relates to a valve body profiling positioning fixture. Background Art

[0002] When processing the valve, it is necessary to use a jig to fix the valve body, and then assemble the valve body parts, mainly using the front positioning block and the right positioning block to position the valve body at the inner corner.

[0003] Since the constraints of conventional fixtures are limited to the front and right sides, the constraint force on the left side is relatively poor, and there is vibration when pressing down, which can easily cause the valve body to shift to the left, and the steel ball will not be pressed into place, which will cause the conventional fixture to have poor stability.

[0004] To this end, we proposed a valve body contour positioning fixture to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of poor stability of conventional jigs and proposes a valve body profiling positioning jig.

The target valve body is sleeved on the profiling positioning core, and the profiling positioning core is inserted into the target valve body to increase the restraining force of the valve body, thereby improving the stability of the valve body after positioning.

[0008] Tighten the screw in the profiling positioning core, use the screw to press on the positioning seat, and fix the profiling positioning core on the screw. When the profiling positioning core is excessively worn, unscrew the screw to facilitate replacement of the profiling positioning core.

[0009] Preferably, the positioning seat comprises a seat body, a front positioning block and a right positioning block, the front end of the right positioning block is fixedly connected to the front positioning block, and the lower ends of the front positioning block and the right positioning block are fixedly connected to the seat body. The front positioning block is used to limit the forward sliding range of the target valve body, and the right positioning block is used to limit the rightward sliding range of the valve block, and the front positioning block and the right positioning block are used to facilitate the positioning of the valve body.

[0010] Preferably, the upper end of the seat body is hollowed out to form a mounting hole, through which a screw is passed and installed on the target table, so as to facilitate fixing the device to the target table.

[0011] Preferably, the profiling positioning core includes a core rod and a nut, and the nut is fixedly connected to the core rod as a whole. The nut is inserted into the front positioning block, and then the screw is tightened in the nut, so that the screw is pressed on the front end of the front positioning block, so that the core rod is pressed on the rear end of the front positioning block, which facilitates the fixed connection between the profiling positioning core and the positioning seat.

[0012] Preferably, the contour positioning core further comprises a hemispherical guide block, which is fixedly connected to the rear end of the core rod, so as to facilitate guiding the target valve body to be sleeved on the core rod.

[0013] Preferably, the screw includes a washer, a knob and a threaded rod, the threaded rod and the knob are fixedly connected as one body, and the threaded rod slides through the washer. The threaded rod is passed through the washer, and then the threaded rod is pressed against the opening of the nut, the knob is operated to screw the threaded rod into the nut, and the knob is further screwed with the help of a wrench to tighten the screw, so as to facilitate the installation and fixing of the contour positioning core.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Put the target valve body on the profiling positioning core, and insert the profiling positioning core into the target valve body to increase the restraint force of the valve body, thereby improving the stability of the valve body after positioning.

[0016] 2. Tighten the screw into the profiling positioning core, use the screw to press on the positioning seat, and fix the profiling positioning core on the screw. When the profiling positioning core is excessively worn, unscrew the screw to facilitate the replacement of the profiling positioning core.

[0017] 3. Use the front positioning block to limit the forward sliding range of the target valve body, and use the right positioning block to limit the right sliding range of the valve block. Use the front positioning block and the right positioning block to facilitate the positioning of the valve body.

[0018] 4. Insert the nut into the front positioning block, and then tighten the screw into the nut so that the screw is pressed against the front end of the front positioning block, thereby pressing the core rod against the rear end of the front positioning block, making it convenient to fix the contour positioning core and the positioning seat.

[0019] 5. Pass the threaded rod through the gasket, and then place the threaded rod against the opening of the nut. Use the knob to screw the threaded rod into the nut, and then use a wrench to further turn the knob to tighten the screw to facilitate the installation and fixation of the contour positioning core.
