Description

A measuring fixture for a spool

technical field

The utility model belongs to the technical field of machinery and relates to a measuring fixture for a valve core.

Background technique

The spool is a valve part that realizes the basic functions of direction control, pressure control or flow control by means of its movement. According to the way of movement, it can be divided into rotary type and translation type; according to the shape, it can generally be divided into spherical, conical, round pie and dome-shaped. Its material is generally mainly bronze or stainless steel, but also plastic, nylon, ceramics, glass and so on.

The spool generally needs to measure multiple data. During the caliper detection, the workpiece needs to be held in hand, which is inconvenient for positioning, the detection accuracy and efficiency are low, and it is easy to scratch the surface of the workpiece; when the height gauge is used for detection, the parts cannot be stabilized and clamped. Accurate; when clamped with a vise, it is easy to cause deformation of the part, the measurement space is also limited, some features cannot be measured, and repeated positioning is required.

The spool is a precision shaft part with small size, many testing items, physical and positional tolerance requirements, and is limited by the positioning and clamping methods and measurement benchmarks. In the past, various inspection tools such as vernier calipers, height gauges, and three-coordinates were required for measurement. , Multiple clamping to complete the detection, which not only makes the measurement and detection efficiency of the valve core low, but also the valve core made of aluminum material is easily pinched, deformed by the vise or scratched by the caliper.

In the above-mentioned measuring fixture for the spool, the adjustment structure includes a guide groove arranged on the test bench to allow the support to slide, and an adjusting bolt can be used to fix the two between the guide groove and the support. . The support can slide in the guide groove. When the support slides to a suitable position for fixing the workpiece, the positions of the two support are fixed by adjusting bolts to prevent the workpiece from loosening during measurement.

In the above-mentioned fixture for measuring the spool, a flange is provided on both sides of the guide groove, and a slider is fixedly connected to the lower end of the support, and the slider is slidably connected in the guide groove. . The slider is clamped in the groove formed by the guide groove and the convex edge, which can ensure that the two supports are kept on the same horizontal plane, so as to avoid errors during measurement.

In the above-mentioned measuring fixture for the spool, the slider is provided with a bolt hole for matching with the adjusting bolt, and the adjusting bolt can make the upper surface of the slider abut against the lower surface of the flange And connect the slider to the measuring platform. The upper end of the slider and the convex edge are pressed against and clamped by adjusting the bolt against the bottom of the guide groove. This fixing method is simple in structure, reliable in fixing, and easy to process the guide groove.

In the above-mentioned fixture for measuring the spool, the positioning structure includes apexes respectively fixedly connected to the two supports, and the apexes can abut against both ends of the workpiece and fix the workpiece. The tip abuts against both ends of the workpiece, which increases the measurement space and does not affect the axial measurement of the workpiece.

In the above-mentioned fixture for measuring the spool, the measuring table includes a measuring panel and support feet arranged at both ends of the measuring panel, and the guide groove is opened on the measuring panel. The supporting feet can increase the height of the measuring table, which facilitates the measurement, and the supporting feet can make the measuring table be placed on a certain plane stably.

Compared with the prior art, the utility model has the following advantages:

1. The fixture adopts two adjustable supports, which improves the versatility of the fixture.

2. In this fixture, two opposing tops abut against the workpiece, which can increase the measurement space and will not affect the axial data measurement of the workpiece.

3. The adjustment structure of this fixture is through the way that the adjustment bolt and the guide groove are abutted, not only the structure is simple, the fixing is reliable, but also the processing of the measuring platform is easy.
