Contents of the invention

The utility model improves the above problems, that is, the technical problem to be solved by the utility model is that the existing inner diameter measurement method has low efficiency and cannot adapt to mass detection and measurement.

The specific embodiment of the utility model is: an adjustable reading-type inner diameter special inspection tool, including a base and a workpiece placement table arranged on the base. The placement table is provided with a fixed convex pin and a movable convex pin. The movable convex pin and the fixed convex pin are on the same straight line, the middle part of the base is provided with a guide groove, the lower end of the movable convex pin extends into the guide groove, and the side of the movable convex pin is provided with a part protruding from the workpiece placement table. The touch rod is provided with a dial gauge fixing device on the base.

Further, the dial indicator fixing device includes a vertical vertical rod, and the upper end of the vertical rod is provided with a sleeve hole, and the axis of the sleeve hole is on the same line as the axis of the feeler rod.

Further, the upper part of the sleeve hole is provided with a locking bolt.

Further, the lower end of the vertical rod is set in the guide groove, the rear side of the vertical rod is provided with a fixed block, the lower end of the fixed block has a flange inserted into the guide groove, and the fixed block is provided with a fixed block locking Bolt, the lower end of the fixing block locking bolt passes through the fixing block and abuts against the upper surface of the base.

Further, sensors are provided on the fixed protruding pin and the movable protruding pin, and a reading display is provided on the side of the base, and the reading display is electrically connected to the sensors on the fixed protruding pin and the movable protruding pin.

Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure, and can easily measure whether the inner diameter reaches the standard; in addition, by setting a reading display device, the measurement of the inner diameter can be realized conveniently; in addition , the utility model can make adaptive adjustments for workpieces of different sizes, and has a wide application range.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figures 1 to 3, an adjustable reading-type inner diameter special inspection tool includes a base 10 and a workpiece placement platform 20 arranged on the base. A fixed convex pin 210 and a movable convex pin are provided on the placement platform 220, the movable convex pin 220 and the fixed convex pin 210 are on the same straight line, the middle part of the base is provided with a guide groove 30, the lower end of the movable convex pin 220 extends into the guide groove 30, and the side of the movable convex pin is provided with There is a feeler rod 211 protruding from the workpiece placement table, and the base is provided with a dial indicator fixing device.

In this embodiment, the dial gauge fixing device includes a vertical vertical rod 410, the upper end of the vertical rod 410 is provided with a sleeve hole 411, and the axis of the sleeve hole 411 is on the same line as the axis of the contact rod 211 When in use, the touch end of the dial gauge 70 is inserted into the sleeve hole 411 toward the contact rod 211, and the upper part of the sleeve hole 411 is provided with a locking bolt to lock the dial gauge.

In order to adapt to workpieces of different sizes, the lower end of the vertical rod 410 is arranged in the guide groove 30, and the rear side of the vertical rod 410 is provided with a fixed block 50, and the lower end of the fixed block has a flange inserted into the guide groove. There is a fixing block locking bolt 510, the lower end of the fixing block locking bolt passes through the fixing block and abuts against the upper surface of the base, and the position of the dial indicator can be easily adjusted by using the fixing block to avoid the workpiece shape affecting the position of the dial indicator. put one's oar in.

Sensors are arranged on the fixed protruding pin and the movable protruding pin, and a reading display 60 is provided on the side of the base, and the reading display 60 is electrically connected to the sensors on the fixed protruding pin and the movable protruding pin.

When in use, the standard workpiece 100 is placed on the workpiece placement table, the fixed convex pin 210 blocks a section of the movable convex pin 220 to make it block the other end, the reading of the dial indicator is determined, and the workpiece to be tested is replaced with a detection dial indicator Whether the readings are consistent, if a reader is installed, the value of the inner diameter measurement can be obtained directly from the reader.

The above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
