Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and in particular to a precision gear measuring device. Background Technology

[0002] In the field of mechanical manufacturing, meshing gears such as half-shaft gears are core components of transmission systems, and their meshing accuracy directly determines transmission efficiency, operational stability, and equipment lifespan. Detecting key parameters such as meshing clearance and runout error in these gears requires high-precision capture of minute displacements during gear meshing. Simultaneously, the measuring device must possess reliable center positioning, flexible multi-directional adjustment, and rapid fixing capabilities to adapt to scenarios such as gear assembly inspection and factory quality verification.

[0003] Currently, the industry mainly relies on two types of technical solutions for precision measurement of meshing gears: one is a dedicated gear measurement center, which obtains tooth surface data by scanning point by point with a contact probe. Although the measurement accuracy is high, the equipment is bulky, expensive, has a complex operation process, and low measurement efficiency, making it difficult to meet the rapid testing needs of the workshop. The other type is simple measuring tools (such as ordinary pitch gauges and dial indicators with universal brackets). These tools have simple structures and low costs.

[0004] However, traditional simple measuring tools are mostly unidirectional fixed structures, lacking multi-dimensional independent adjustment mechanisms, making it difficult to quickly achieve center alignment when gears mesh, and unable to flexibly adapt to the installation and positioning requirements of different specifications of half-shaft gears, resulting in long calibration and positioning time before measurement and cumbersome operation. Utility Model Content

[0005] The purpose of this invention is to provide a precision gear measuring device, which aims to solve the problems of long calibration and positioning time and cumbersome operation of traditional measuring tools.

[0006] To achieve the above objectives, this utility model provides a precision gear measuring device, including a base, a measuring component, and a sliding adjustment component. The measuring component is disposed on one side of the base. The sliding adjustment component includes a first sliding seat, a second sliding seat, a first spindle, a second spindle, a column, a spring adjusting rod, a spline concentric ring, and a wing nut. The column is fixedly connected to the base and located on one side of the base. The first sliding seat is disposed on one side of the column. The first spindle is slidably connected to the first sliding seat and located on the side of the first sliding seat away from the column. The spline concentric ring is disposed on the side of the first spindle away from the first sliding seat. The second sliding seat is disposed on one side of the base. The second spindle is slidably connected to the second sliding seat and located on the side of the second sliding seat away from the base. The spring adjusting rod is disposed on the side of the second sliding seat away from the first sliding seat.

[0007] The sliding adjustment assembly further includes a flat washer, which is disposed on one side of the wing nut.

[0008] The base has a sliding seat pressure plate, which is located on both sides of the second sliding seat.

[0009] The measuring component includes a dial indicator, a dial indicator contact head, and a dial indicator mounting base. The dial indicator contact head is mounted on the side of the second sliding seat away from the first sliding seat. The dial indicator mounting base is fixedly connected to the base and is located on the side of the base near the dial indicator contact head. The dial indicator is mounted on the dial indicator mounting base.

[0010] This utility model discloses a precision gear measuring device. The base provides support and installation conditions for the measuring component and the sliding adjustment component. The second spindle can move linearly along the base track on the second sliding seat to achieve coarse or fine adjustment of the X-axis. The first spindle moves up and down along the column on the first sliding seat to achieve adjustment of the Z-axis. The spring adjusting rod, through a threaded pair, provides a small, flexible preload or fine displacement adjustment for the sliding seat or measuring head, eliminating gaps and ensuring measurement stability. The combination of the wing nut and the spline concentric sleeve allows the user to quickly and manually lock or loosen the first spindle without tools, facilitating rapid coarse adjustment and reliable fixation. The spline concentric sleeve ensures no circumferential rotation during locking, maintaining alignment accuracy. This solves the problems of long calibration and positioning times and cumbersome operation associated with traditional measuring tools. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] Please see Figures 1 to 3 This utility model provides a precision gear measuring device, including a base 11, a measuring component, and a sliding adjustment component. The measuring component is disposed on one side of the base 11. The sliding adjustment component includes a first sliding seat 1, a second sliding seat 14, a first spindle 13, a second spindle 3, a column 12, a spring adjusting rod 7, a spline concentric sleeve 19, and a wing nut 18. The column 12 is fixedly connected to the base 11 and is located on one side of the base 11. The first sliding seat 1 is disposed on one side of the column 12. The first spindle 13 is slidably connected to the first sliding seat 1 and is located on the side of the first sliding seat 1 away from the column 12. The spline concentric sleeve 19 is disposed on the side of the first spindle 13 away from the first sliding seat 1. The second sliding seat 14 is disposed on one side of the base 11. The second spindle 3 is slidably connected to the second sliding seat 14 and is located on the side of the second sliding seat 14 away from the base 11. The spring adjusting rod 7 is disposed on the side of the second sliding seat 14 away from the first sliding seat 1.

[0018] In this embodiment, the base 11 provides support and installation conditions for the measuring component and the sliding adjustment component. The second spindle 3 can move linearly along the track of the base 11 on the second sliding seat 14 to achieve coarse or fine adjustment of the X-axis. The first spindle 13 moves up and down along the column 12 on the first sliding seat 1 to achieve adjustment of the Z-axis. The spring adjusting rod 7 can provide a small, flexible preload or fine displacement adjustment for the sliding seat or measuring head through the threaded pair, eliminating gaps and ensuring measurement stability. The combination of the wing nut 18 and the spline concentric sleeve 19 allows the user to quickly and manually lock or loosen the first spindle 13 without tools, facilitating quick coarse adjustment and reliable fixation. The spline concentric sleeve 19 ensures no circumferential rotation during locking, maintaining alignment accuracy. This solves the problems of long calibration and positioning time and cumbersome operation of traditional measuring tools.

[0019] Furthermore, the sliding adjustment assembly also includes a flat washer 16, which is disposed on one side of the wing nut 18.

[0020] In this embodiment, the flat washer 16 is provided to enhance the stability of the connection between the wing nut 18 and the spline concentric sleeve 19, and to prevent the wing nut 18 from loosening.

[0021] Furthermore, the base 11 has a sliding seat pressure plate 20, which is located on both sides of the second sliding seat 14.

[0022] In this embodiment, the sliding seat pressure plate 20 is provided to firmly constrain the sliding track of the base 11, ensuring the rigidity of the entire measuring frame.

[0023] Furthermore, the measuring component includes a dial indicator 5, an indicator contact head 4, and a dial indicator mounting base 6. The indicator contact head 4 is mounted on the side of the second sliding seat 14 away from the first sliding seat 1. The dial indicator mounting base 6 is fixedly connected to the base 11 and is located on the side of the base 11 close to the indicator contact head 4. The dial indicator 5 is mounted on the dial indicator mounting base 6.

[0024] In this embodiment, the dial indicator 5 is rigidly fixed to the base 11 by the dial indicator fixing seat 6, and the dial contact head 4 is fixed to the second sliding seat 14, which is equivalent to directly contacting the workpiece being measured. The minute size changes or positional deviations of the workpiece are amplified and converted into pointer readings on the dial of the dial indicator 5, thereby achieving high-precision (typically 0.01mm level) non-electrical measurement.

[0025] The following is a method of using a precision gear measuring device according to this utility model: Prepare the first and second half-shaft gears to be tested. Install the second half-shaft gear on the mandrel seat composed of the second mandrel 3, the spline concentric sleeve 19, and the first spherical washer 10, and fix it with standard spring washers 2 and bolts. After the whole assembly is fixed, it can rotate in the Z-axis and is fixed to the first sliding seat 1 with bolts. It can slide to the right through the guide rail of the base 11. The spring system composed of the spring adjusting rod 7, the open sleeve 8, and the spring 9 set on the right side makes the first sliding seat 1 close to the left. Meanwhile, the first half-shaft gear is fixed to the seat composed of the second spindle 3 and the first spherical washer 10 in a similar manner. Its bottom is fixed to the second sliding seat 14 by six bolts. The second sliding seat 14 can slide up and down the column 12. During measurement, the teeth of the first half-shaft gear and the second half-shaft gear are aligned, and the bottom of the first half-shaft gear is locked by a locking mechanism composed of a double-ended stud 15, the flat washer 16, and the spring washer 17. By rotating the first half-shaft gear, the meshing second half-shaft gear can be rotated. At the same time, since the second half-shaft gear is a soft limit, the runout generated by meshing will cause the second half-shaft gear and its base 11 to slide to the right. At this time, the runout value will be fed back to the dial indicator 5 through the dial contact head 4.

[0026] The above-disclosed embodiments are merely preferred embodiments of a precision gear measuring device of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
