Description

Technical Field

[0001] This utility model relates to the technical field of internal hole measuring devices, and in particular to a wireless internal hole measuring device. Background Technology

[0002] In the precision manufacturing process of parts, many internal hole dimensions need to be measured during machining to determine whether they meet the machining requirements of the drawings. When measuring the internal hole dimensions of a part on a machine tool, it is not removed from the fixture to prevent deviations in machining dimensions caused by re-clamping. Therefore, existing internal hole measuring devices can be handheld and inserted into the machine tool for rapid measurement.

[0003] When existing internal hole measuring devices measure dimensions using pneumatic gauges or measuring sensors, the handheld terminal needs to be connected to an air pipe that transmits compressed air or a sensor cable, which causes inconvenience to the movement of the handheld terminal and affects the internal hole measurement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-2 This utility model provides a technical solution: a wireless internal hole measuring device, comprising:

[0027] Handle 1, which contains a measuring sensor 11, a circuit board and a display screen 12. The circuit board includes a data processing module and a wireless signal transmitting module. The data processing module is electrically connected to the measuring sensor 11. The wireless signal transmitting module is used to communicate with the wireless signal receiving module of the computer. The display screen 12 is electrically connected to the data processing module.

[0028] The inner hole probe 2 is fixedly installed at one end of the handle 1. The inner hole probe 2 includes a ball head contact 21 and a lifting rod. The two ball head contacts 21 are symmetrically arranged on both sides of the inner hole probe 2. One end of the lifting rod contacts the measuring sensor 11.

[0029] The measuring sensor is integrated into the handle, and data is read directly through the screen at the top of the handle, enabling visualized reading of the measurement results. This facilitates quick measurement of the inner hole dimensions of parts when held in a machine tool. Simultaneously, wireless data transmission technology enables data uploading, eliminating the need for external air hoses or cables, simplifying operation, and allowing measurement results to be uploaded directly to a computer wirelessly.

[0030] A push-button switch 13 is also provided on the handle 1. The push-button switch 13 is used to control the power supply to and from the circuit board and the display screen 12. When the push-button switch 13 is pressed, the measurement data is transmitted wirelessly through the wireless signal transmission module of the circuit board. During wireless data transmission, the measurement results are sent to the computer through a custom communication protocol. The computer can collect the data transmitted by the measuring device by configuring the receiving end.

[0031] The push-button switch 13 is located at the end of the handle 1 near the display screen 12 to prevent accidental operation of the push-button switch 13.

[0032] Working Principle: When measuring the inner diameter of a part clamped on a machine tool, the operator holds handle 1 and inserts the inner diameter probe 2 into the inner diameter of the part. The ball joint contact 21 is pressed inwards by the probe, and the back of the ball joint contact 21, through a tapered pin, pushes the lifting rod to move along the axial direction. The lifting rod presses against the measuring sensor 11, which detects the displacement of the lifting rod. The data processing module on the circuit board processes the displacement data and converts it into the inner diameter, thus obtaining the measurement data. The lifting rod is elastically connected to the inner diameter probe 2 and can be reset after the probe 2 is removed from the part. The inner diameter probe 2 is a conventional probe, and the working principle of measuring the inner diameter through the ball joint contact 21, the lifting rod, and the sensor is existing technology and will not be elaborated further.

[0033] The pairing mode between the computer's wireless signal receiving module and the wireless signal transmitting module in the controller 1 can be a one-to-one mode or a one-to-many mode, that is, one wireless receiver corresponds to one wireless transmitter, or one wireless receiver corresponds to multiple wireless transmitters.

[0034] Example 2

[0035] Based on the above embodiments, this embodiment further improves upon the following technical solution: the handle 1 has a spindle-shaped structure.

[0036] The handle 1 is "thin at both ends and thick in the middle" to facilitate gripping and operation, while also further preventing accidental operation of the button switch 13.

[0037] Example 3

[0038] Based on the above embodiments, this embodiment further improves upon the following technical solution: a cuboid housing 14 is provided at one end of the handle 1, and a display screen 12 is provided on the cuboid housing 14.

[0039] The cuboid housing 14 facilitates the inverted placement of the internal bore measuring device and makes it easy to store the device. Furthermore, the thickness of the cuboid housing 14 is greater than the diameter of the internal bore probe 2 and the diameter of the handle 1, effectively protecting the internal bore probe 2 when the internal bore measuring device is stored.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
