A measuring device for the width between disc-type friction blocks

Abstract

This utility model discloses a measuring device for the width between disc-type friction blocks, belonging to the field of friction block measurement technology. The device includes a housing, an adjustment mechanism shaft, a transition seat, a synchronization mechanism shaft, and a dual measuring scale system. Its key feature is that the micrometer drum drives the adjustment mechanism wheel to rotate via an internal adjustment mechanism gear ring, which in turn drives the adjustment mechanism shaft, fixedly connected to the sun gear, to rotate. The synchronization mechanism shaft rotates synchronously via a spline connection, pushing the transition seat to move axially, causing the second adjustment sleeve fixed to the transition seat and the first adjustment sleeve fitted onto the synchronization mechanism shaft to expand bidirectionally, driving the first and second measuring scales to synchronously displace and contact the inner wall of the friction block. The measured value is read dually through the main scale of the measuring scale and the micrometer-level scale of the micrometer drum. This utility model automatically eliminates gap errors, is easy to operate, and solves the technical problem of insufficient measurement accuracy of traditional calipers.

Description

Technical Field

[0001] This utility model relates to the field of disc friction block measurement technology, and in particular to a measuring device for the width between disc friction blocks. Background Technology

[0002] Currently, the width between disc friction blocks is measured using calipers. However, caliper measurements are inaccurate, and since manual measurement cannot eliminate the gaps, the measurement error is significant. Therefore, a device is needed to measure the width between disc friction blocks, providing a more intuitive and accurate representation of their spacing. Utility Model Content

[0003] The technical solution of this utility model to solve the above-mentioned technical problems is to provide a measuring device for the width between disc-type friction blocks, comprising:

[0004] case;

[0005] The adjustment mechanism shaft is rotatably mounted on the housing;

[0006] The transition seat is sleeved on the shaft of the adjusting mechanism and can move axially.

[0007] The synchronizing mechanism shaft is fixedly connected to the transition seat and splinedly connected to the adjusting mechanism shaft, restricting their relative rotation.

[0008] Adjustment sleeve one is fitted onto the shaft of the synchronization mechanism;

[0009] Adjusting sleeve two is fixed on the transition seat;

[0010] The first measuring ruler is fixed on the second adjusting sleeve;

[0011] The second measuring ruler is fixed to the first adjusting sleeve;

[0012] Adjustment mechanism wheel, which is mounted on the housing by fixing pin;

[0013] Adjust the sun gear, fix it on the adjustment mechanism shaft and mesh it with the adjustment mechanism wheel;

[0014] The differential cylinder contains an adjustment mechanism gear ring, which is sleeved on the adjustment mechanism shaft; and the adjustment mechanism gear ring meshes with the adjustment mechanism wheel.

[0015] The support base is fixed to the end of the adjustment mechanism shaft.

[0016] Furthermore, the measuring device for the width between the disc friction blocks also includes: fixed pin one, fixed pin two, fixed pin three and fixed pin four; fixed pin one restricts the axial relative movement between the transition seat and the synchronous mechanism shaft; fixed pin two and fixed pin three fix the transition seat and the synchronous mechanism shaft; the first measuring scale and the adjusting sleeve two are fixed by fixed pin four, and the second measuring scale and the adjusting sleeve one are fixed by fixed pin five.

[0017] Furthermore, the adjustment mechanism wheel is mounted on the housing via the adjustment mechanism support sleeve and is fixedly connected to the housing via the adjustment mechanism wheel fixing pin.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. High-precision measurement: The rotary motion is converted into precise angular displacement of the adjustment mechanism shaft through a gear transmission system driven by the micrometer tumbler (adjustment mechanism gear ring → adjustment mechanism wheel → adjustment sun gear). This displacement is then transmitted radially to the measuring scale via a spline-connected synchronous mechanism shaft. Combining the main scale of the first measuring scale with the micrometer-level scale of the micrometer tumbler, a dual reading system is achieved, with a measurement accuracy of up to 0.01mm, completely solving the problem of large errors in traditional caliper manual measurement.

[0020] 2. Automatic gap elimination: Adjusting sleeve one and adjusting sleeve two expand synchronously in both directions under the drive of the synchronous mechanism shaft. The rigid linkage between the transition seat and the measuring scale is ensured by the fixed pin system, which automatically fills the gap of the friction block and avoids measurement distortion caused by manual operation.

[0021] 3. Strong structural stability: The spline connection restricts the relative rotation of the adjustment mechanism shaft and the synchronization mechanism shaft, ensuring displacement synchronization; the adjustment mechanism wheel is double-fixed to the housing by the support sleeve and pins, suppressing gear transmission vibration; the fixed pin group locks all moving parts, eliminating the impact of assembly clearance on accuracy.

[0022] 4. Convenient and efficient operation: The measuring scale can be automatically expanded to contact the inner wall of the friction block by rotating the micrometer drum with one hand, and the superimposed value of the main scale and the micrometer drum can be directly read, which greatly improves the detection efficiency and is suitable for rapid quality inspection scenarios on the production line.

[0051] Working principle:

[0052] The measuring device for the width between the disc friction blocks in this application converts the rotational motion of the differential drum into the radial linear displacement of the measuring ruler through a gear transmission system, and achieves high-precision measurement by combining a dual reading system.

[0053] The specific workflow is as follows:

[0054] 1. Driving Phase:

[0055] The rotating differential cylinder 2 drives the internal adjustment mechanism gear ring 4 to rotate;

[0056] The adjusting mechanism gear ring 4 drives the adjusting mechanism wheel 3, which meshes with it, to rotate;

[0057] Adjustment mechanism wheel 3 drives adjustment sun gear 18 to rotate through meshing;

[0058] The sun gear 18 is fixed on the adjustment mechanism shaft 5, driving the adjustment mechanism shaft 5 to rotate synchronously.

[0059] 2. Displacement Transition Stage:

[0060] The rotational motion of the adjusting mechanism shaft 5 is transmitted to the synchronizing mechanism shaft 9 through a spline connection, forcing the synchronizing mechanism shaft 9 to rotate synchronously;

[0061] The rotation of the synchronous mechanism shaft 9 drives the transition seat 7 to rotate through the fixed pin 8; (the inner side of the transition seat (7) is provided with a slanted groove or thread structure, which cooperates with the convex pin on the synchronous mechanism shaft (9) to convert the rotational motion into axial displacement);

[0062] The rotation of the transition seat 7 drives the adjusting sleeve 14 to move axially through the fixing pin 2 15 and the fixing pin 3 6;

[0063] Simultaneously, adjusting sleeve 10 is driven outward by the synchronous mechanism shaft 9. 3. Measurement reading:

[0064] The two measuring scales expand synchronously until they contact the inner wall of the friction block, and the integer millimeter value is read through the main scale on the surface of the first measuring scale 13 and the second measuring scale 12.

[0065] The micron-level margin (e.g., 0.01 mm accuracy) is read through the precise scale of the differential cylinder 2;

[0066] Total width = main scale value + micrometer thimble reading.
