Description

Technical Field

[0001] This utility model belongs to the field of thread inspection technology, and in particular relates to a three-coordinate desktop adjustable thread plug gauge measuring device. Background Technology

[0002] Electric plug gauges are a type of inspection device in the mechanical field, commonly used to measure dimensions such as hole diameters. Cylindrical threads, also known as ordinary threads, are mainly used for connecting and fastening parts, and are most widely used in the mechanical manufacturing field, especially in aerospace and other military products. Cylindrical thread plug gauges are the primary measuring instruments used to inspect the quality of thread machining, ensuring that the geometric parameters of the thread plug gauge meet metrological performance requirements. These plug gauges can be divided into three types: ordinary coarse thread, fine thread, and pipe thread. Thread plug gauges with a pitch of 0.35 mm or less, and those with a precision of Class 2 or higher, and those with a pitch of 0.8 mm or less and a precision of Class 3, do not have a stop end probe. Thread plug gauges with a pitch of less than 100 mm are tapered shank thread plug gauges, while those with a pitch of more than 100 mm are double-shank thread plug gauges.

[0003] The electric electronic plug gauges currently in use have an inductor coil directly mounted on a measuring arm of an elastomer. When used for online inspection, because there is grinding fluid in the hole being inspected, the grinding fluid can easily flow into the inductor coil through the probe, measuring jaws, and elastomer during inspection, causing changes in inductance and resulting in drift in the measured value and unstable inspection results. Utility Model Content

[0004] In view of this, the present invention aims to propose a three-coordinate desktop adjustable thread plug gauge measuring device to solve the problem that when grinding fluid is present in the hole being measured, the grinding fluid can easily flow into the inductor coil through the probe, jaws, and elastic body during the test, causing changes in inductance and resulting in drifting of the measured value and unstable test results.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides a three-coordinate desktop adjustable thread plug gauge measuring device, including a dual-axis moving base, a height gauge, an electronic plug gauge, and a worktable. The dual-axis moving base is provided with an electronic plug gauge mounting fixture, on which the electronic plug gauge is mounted. A display panel is provided on the side of the dual-axis moving base and locked to the side of a vertical mounting plate. The height gauge and the electronic plug gauge are connected to the display panel. The dual-axis moving base is located directly behind the height gauge. The workpiece to be measured is placed on the workpiece placement table of the dual-axis moving base, and the base of the dual-axis moving base is locked to the worktable.

[0007] Furthermore, a fine-tuning nut is provided on the vertical moving screw of the height measuring instrument, and the side of the height measuring instrument is rotatably fixed on the vertical moving screw. A pressure sensor is provided on the measuring contact of the height measuring instrument, and an infrared laser sensor is externally placed on the side of the measuring contact. Both the pressure sensor and the infrared laser sensor are connected to the display panel.

[0008] Furthermore, in the dual-axis movable base, a front-to-back movable mounting plate is locked on the mounting platform, a first lead screw nut seat is locked under the front-to-back movable mounting plate, a first movable stage is locked on the front-to-back movable mounting plate, a first lead screw is mounted on the first movable stage via a bearing, the middle of the first lead screw is threaded to the first lead screw nut seat, a first slider is slidably fixed on a first linear slide rail, the first linear slide rail is fixed to the mounting platform, the first slider is slidably fixed on the first linear slide rail, the first slider is locked to the first movable stage, a first adjusting handle is fixed to the top of the first lead screw, the center of the workpiece placement stage is locked to the upper surface of the first movable stage via a nut, and a groove is provided on the side of the workpiece placement stage. A locking positioning block is installed inside the slot. A third locking nut is threadedly fixed to the side of the first moving table. The screw of the third locking nut abuts against the side of the positioning block. A vertical mounting plate is locked to one side of the workpiece placement table. The vertical mounting plate is fixed to a second lead screw via a bearing. The end of the second lead screw is locked to a second adjusting handle. The second lead screw is connected to a second fixed table via a second lead screw nut seat. A second fixed block is locked to the second fixed table. A second linear slide rail is symmetrically fixed in the middle of the vertical mounting plate. A second slider is slidably fixed on the second linear slide rail. The second slider is locked to the bottom of the second fixed table. An electronic plug gauge mounting fixture is fixed on the second fixed table.

[0009] Furthermore, the electronic plug gauge mounting fixture includes a fourth adjusting handle, a first fixed frame, and a second fixed frame. The fourth adjusting handle locks the outer surface of the electronic plug gauge. The first fixed frame and the second fixed frame are symmetrically arranged and locked to each other. The side mounting plate of the second fixed frame is locked to the second fixed platform. Both the first fixed frame and the second fixed frame have an arc-shaped groove in the middle, and the arc-shaped groove is adapted to the shape of the electronic plug gauge.

[0012] Compared with existing technologies, the three-coordinate desktop adjustable thread plug gauge measuring device of this utility model has the following advantages:

[0013] (1) In the contact measurement of this utility model, the contact pressure between the contact head and the object being measured is monitored in real time to avoid overload damage to the workpiece or measurement errors. The infrared laser sensor supports non-contact measurement, complementing the contact measurement and expanding the application scenarios of the three-coordinate desktop adjustable thread plug gauge measuring device. The combination of pressure sensor and infrared laser sensor measurement realizes high-precision detection of electric electronic plug gauges. The display panel 22 centrally displays parameters such as contact pressure, laser distance measurement value, and height fine adjustment in real time, simplifying the operation process. In actual use, the measuring contact head with pressure sensor and the infrared laser sensor can be selected separately or used in combination for flexible adjustment of the electric plug gauge, and the display paths of the two on the display screen do not interfere with each other. The pressure contact head and the infrared laser sensor are physically separate modules, installed in the contact area and side of the height measuring instrument, respectively.

[0014] (2) The dual-axis moving base of this utility model, in conjunction with the electronic plug gauge mounting fixture, allows for flexible adjustment of the measurement position and angle, adapting to workpieces of different sizes and significantly improving the equipment's versatility. The height gauge and electronic plug gauge are linked, achieving integrated detection of complex parameters through dual-sensor collaborative measurement (height combined with hole diameter / depth measurement), reducing errors from repeated clamping. The dual-axis moving base is locked to the worktable using a rigid locking structure, avoiding displacement deviations caused by vibration or load during measurement and ensuring repeatability. The display panel is directly fixed to the side of the vertical mounting plate, reducing signal transmission interference, displaying measurement data in real time, and improving reading stability.

[0015] (3) In this utility model, the first fixed frame and the second fixed frame are symmetrically arranged. The arc-shaped groove adapts to the shape of electronic plug gauges of different diameters, supporting quick replacement of plug gauges of various specifications and significantly improving the versatility of the clamp. The fourth adjusting handle 20 adopts a threaded tightening structure. The outer surface is locked by rotating the adjusting handle, avoiding damage to the plug gauge surface caused by traditional rigid clamping, while ensuring clamping stability. After loosening the interlocking bolts, the first fixed frame and the second fixed frame can be separated, which facilitates the replacement of parts and reduces maintenance costs.
