Description

Technical Field

[0001] This utility model relates to the field of parts spraying technology, and in particular to a multifunctional internal hole thread gauge. Background Technology

[0002] In modern industrial development systems, threads are needed for connection, fixation, and displacement. Their excellent fixing strength and simple operation process make them widely used. In certain fields, the precision requirements for connection are extremely high. Therefore, a multi-functional internal thread gauge has emerged to meet the industry's multi-functional, multi-angle, and multi-scale measurement of threaded holes, thereby producing more suitable accessories to match them.

[0003] Most multi-functional internal thread gauges on the market currently use an external expansion version for measurement. The entire measuring end is placed inside the test object, and the expansion is judged by expanding a specific distance to determine whether the expansion is in place. When it is in place, it will show that it has passed, proving that the quality of the threaded hole is qualified. At the same time, the data of the threaded hole is transmitted to the equipment to record the production status. Its multi-angle measurement allows it to test holes of more sizes, thereby meeting the needs of different manufacturers.

[0004] Existing multifunctional internal thread gauges can obtain test data very quickly, but their internal components usually develop a certain range of errors after a period of use. Although the errors are small, they can be fatal on precision instruments. Calibration is performed by direct measurement with a micrometer, which makes it impossible to ensure that the outer wall is vertical or horizontal. In order to meet the processing requirements, meet the requirements of rapid measurement and rapid calibration, and solve the calibration difficulties in existing technologies, a multifunctional internal thread gauge is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multifunctional internal thread gauge, which aims to improve the problem of difficult calibration in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional internal thread gauge includes a horizontal support, a movable gauge slidably connected to the inner wall of the horizontal support, an expansion mechanism fixedly connected to the bottom of the movable gauge, and a movable mechanism slidably connected to the inner wall of the movable gauge.

[0008] The expansion mechanism includes a fixed housing, the top of which is fixedly connected to the bottom of the movable gauge. A turntable is slidably connected to the inner wall of the fixed housing. A motor is installed on the inner wall of the movable gauge. A support plate is rotatably connected to the bottom of the turntable. A sliding groove is provided on the inner wall of the fixed housing. A movable column is slidably connected to the inner wall of the turntable. A sliding block is fixedly connected to the bottom of the movable column. A connecting block is fixedly connected to one side of the sliding block. A synchronization component is fixedly connected to one side of the connecting block.

[0009] As a further description of the above technical solution:

[0010] The moving mechanism includes a pressing block, the outer wall of which is slidably connected to the inner wall of the expanding mechanism. Two limiting posts are fixedly connected to the inner wall of the pressing block, and springs are sleeved on the outer walls of the two limiting posts. A locking block is fixedly connected to the inner wall of the pressing block, and a sliding groove is provided on one side of the pressing block.

[0011] As a further description of the above technical solution:

[0012] The synchronization component includes a measuring plate, one side of which is fixedly connected to one side of the connecting block, and a telescopic rod is fixedly connected to one side of the measuring plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when measurement is required, the measuring end of the device is first placed into the thread micrometer for calibration. Then, the motor is started, and the motor drives the turntable to rotate. The eccentric groove inside the turntable drives the moving column to move. The bottom sliding groove restricts the moving column to move only along the specified trajectory inside the groove, thereby driving the sliding block to extend and retract to complete the measurement action. To avoid deviation or failure of the measuring plate to fit tightly, the telescopic rod will synchronously assist the measuring plate to ensure that it remains balanced and ensures the measurement accuracy. Finally, the scale is calibrated, and the above pressing, unlocking, and moving calibration steps are repeated to measure different positions of the workpiece.

[0025] 2. In this utility model, when it is necessary to measure different positions, press the two pressing blocks inward to bring them closer to each other. During the pressing process, the spring will be squeezed and completely embedded in the groove of the pressing block. The limiting post can prevent the pressing block from being misaligned. At the same time, the pressing block drives the locking block to move inward synchronously, so that the locking block is released from the limiting range of the horizontal bracket, thereby unlocking. At this time, the device can be moved. The horizontal bracket is used to measure whether the position of the double threaded hole is horizontal, and the sliding groove can regulate the displacement trajectory of the device to ensure stable movement.

[0049] Specifically, the limiting post 42 has a circular cross-section to reduce friction with the spring 43 and the pressing block 41.

[0050] The implementation principle of this application embodiment is as follows: When measurement is required, the measuring end of the device is first placed into the thread micrometer for calibration. At this time, the motor 33 is started, and then the motor 33 drives the turntable 32 to rotate. Then, due to the eccentric groove inside the turntable 32, the moving column 36 moves. Due to the existence of the bottom sliding groove 35, the moving column 36 driven by the moving column 36 can only perform the specified movement within the groove. Finally, the sliding block 37 is driven to extend and retract. In order to prevent deviation or failure to fit tightly, the telescopic rod 392 will assist the measuring plate 391 to maintain its balance.

[0051] When different positions need to be measured, press the pressing block 41 inward. At this time, the two pressing blocks 41 will come closer together, which will squeeze the spring 43, making it completely sink into the groove of the pressing block 41. The limiting post 42 prevents it from being misaligned. Then the locking block 44 will be driven to move inward together, making it move out of the range of the horizontal bracket 1, thereby unlocking it. Then it can be moved. The horizontal bracket 1 can measure whether the position of the double threaded hole is horizontal. The presence of the slide groove 45 makes its displacement more standardized. Finally, calibrate the scale, and then repeat the above steps to measure the workpiece.
