Description

Technical Field

[0001] This utility model relates to the field of worm gear measuring devices, and more particularly to a comprehensive worm gear measuring device. Background Technology

[0002] Worm gears are mechanical structures used to achieve large transmission ratios between perpendicularly intersecting shafts. They are commonly used in applications such as speed reduction mechanisms and lifting equipment where high precision and stability are required. Because the meshing relationship of worm gears is quite precise, involving complex factors such as surface contact and sliding friction, their manufacturing precision affects important parameters such as transmission efficiency, noise control, and service life.

[0003] In the existing technology, after the worm gear parts are machined, their dimensions need to be measured to ensure that their machining accuracy meets the assembly requirements. However, the existing inspection methods are difficult to automate the inspection of multiple parameters such as tooth profile, tooth pitch, coaxiality and meshing state on the same platform. The measurement efficiency is low, and the workpiece clamping and replacement are inconvenient, making it difficult to meet the rapid measurement needs of workpieces of various specifications.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 5As shown, this utility model embodiment provides a worm gear integrated measuring device, including a base 1, a dual-axis moving mechanism 2, a laser measuring sensor 3, a lifting mechanism 4, an upper clamping rod 51, a lower clamping rod 52, a positioning pawl 6, and a rotary drive mechanism 7. The positioning pawl 6 is located on the side of the base 1 and is connected to the bottom of the lower clamping rod 52. The positioning pawl 6 is used to fix the lower clamping rod 52. The top of the lower clamping rod 52 has a first tip 521. The upper clamping rod 51 is located above the lower clamping rod 52 and has a second tip 511 at its bottom. The first tip 521 and the second tip 511 respectively abut against the upper and lower end faces of the worm gear. The rotary drive mechanism 7 is located inside the base 1 and is connected to the positioning pawl 6. The rotary drive mechanism 7 is used to drive the positioning pawl 6 to rotate. The lifting mechanism 4 is located on the base 1. The movable end of the lifting mechanism 4 is connected to the upper clamping rod 51. The lifting mechanism 4 is used to drive the upper clamping rod 51 to move up and down in the vertical direction. When clamping the worm gear to be measured, the operator can place the worm gear vertically on the first tip 521 at the top of the lower clamping rod 52. The first tip 521 makes point contact with the lower end face of the worm gear, thereby providing lower limit support for the worm gear. Subsequently, the lifting mechanism 4 drives the upper clamping rod 51 to move downward, so that the second tip 511 at the bottom of the upper clamping rod 51 abuts against the upper end face of the worm gear, forming an upper and lower clamping state, improving the clamping stability of the workpiece, and quickly adapting to clamping workpieces of different specifications. In this embodiment, the lifting mechanism 4 is a lead screw linear module. The rotary drive mechanism 7 drives the positioning claw disk 6 to rotate, thereby driving the lower clamping rod 52 connected to it and the clamped worm gear to rotate synchronously, which facilitates the laser measurement sensor 3 to realize laser scanning measurement of the workpiece at various angles.

[0037] The dual-axis moving mechanism 2 is mounted on the base 1 at the side end of the positioning claw disk 6. A fixed seat 30 is provided at the movable end of the dual-axis moving mechanism 2, and the laser measuring sensor 3 is mounted on the fixed seat 30. The laser measuring sensor 3 emits a detection laser towards the worm gear held at the side end. During the measurement process, the worm gear rotates slowly under the action of the rotation drive mechanism 7. Driven by the dual-axis moving mechanism 2, the laser measuring sensor 3 can adjust its detection position along the X and Y axes to achieve comprehensive scanning of the workpiece. Through a combination of static and dynamic measurements, multiple parameters such as tooth profile error, tooth pitch error, and eccentricity are obtained, simplifying the workpiece change and measurement process and improving overall measurement efficiency.

[0038] like Figure 4 and Figure 5As shown, the positioning claw disk 6 further includes a mounting base 61, a gear disk 62, a drive worm gear rod 63, a supporting worm gear 64, and a sliding clamping block 65. The gear disk 62 is rotatably disposed on the top of the mounting base 61. The bottom of the gear disk 62 is provided with an annular toothed groove 621. The drive worm gear rod 63 and the supporting worm gear 64 are respectively spaced apart along the circumference of the annular toothed groove 621. The drive worm gear rod 63 is used to drive the gear disk 62 to rotate. The top of the mounting base 61 is provided with a plurality of limiting grooves 610. The sliding clamp 65 is located within the limiting groove 610 and can move along the extending direction of the limiting groove 610. The top of the gear plate 62 is provided with a spiral annular groove 622, and the bottom of the sliding clamp 65 is provided with a plurality of positioning protrusions 651. The positioning protrusions 651 are located within the spiral annular groove 622. The positioning protrusions 651 are used to drive the sliding clamp 65 to move along the limiting groove 610 as the spiral annular groove 622 rotates, so as to realize the clamping or release of the lower clamping rod 52. When clamping the lower clamping rod 52, the operator can insert the lower clamping rod 52 into the center position of the positioning claw disk 6. At this time, the sliding clamping block 65 is in the open state. Subsequently, the drive worm gear 63 can drive the gear disk 62 to rotate. As the gear disk 62 rotates, the spiral annular groove 622 at its top also rotates synchronously. The bottom of the sliding clamping block 65 located in the limiting slide groove 610 is provided with a positioning protrusion 651 embedded in the spiral annular groove 622. Affected by the spiral guidance, the sliding clamping block 65 can move inward along the direction of the limiting slide groove 610. The lower clamping rod 52 is positioned and clamped. It should be noted that when the gear plate 62 rotates in the forward direction, the sliding clamping block 65 slides towards the center and clamps the lower clamping rod 52 to form a stable locking state. When rotating in the reverse direction, the sliding clamping block 65 can be driven to retract outward, thereby releasing the lower clamping rod 52. This allows for the replacement of lower clamping rods 52 of different lengths or structures to lift the workpiece to the measurement reference height. In addition, lower clamping rods 52 of different structures can also be adapted according to the bottom shape of the workpiece, thereby improving the clamping stability of the workpiece.

[0039] like Figure 2 and Figure 3As shown, the rotary drive mechanism 7 further includes a rotary motor 71, a driving gear 72, a driven gear 73, a rotary shaft 74, a rotary disk 75, and a sleeve base 76. The rotary disk 75 is rotatably mounted on the top of the sleeve base 76. The positioning claw disk 6 is mounted on the rotary disk 75. The rotary shaft 74 is located inside the sleeve base 76, and its top is connected to the rotary disk 75. The rotary motor 71 is located inside the base 1, with its output shaft facing upwards and connected to the driving gear 72 to drive... The driving gear 72 rotates, and the driven gear 73 is located at the bottom of the rotating shaft 74. The driving gear 72 and the driven gear 73 are connected by meshing. As the driven gear 73 rotates, the rotating shaft 74 can rotate accordingly, thereby driving the rotating disk 75 connected to its top to rotate synchronously. This also drives the positioning claw disk 6 fixed on the rotating disk 75 and the worm gear it holds to rotate evenly, preventing swaying and facilitating the laser measuring sensor 3 to continuously scan parameters such as tooth profile and tooth pitch at different angles, thereby achieving comprehensive measurement.

[0040] like Figure 1 As shown, the dual-axis moving mechanism 2 further includes an X-axis moving module 21 and a Y-axis moving module 22. The X-axis moving module 21 is mounted on the base 1. The movable end of the X-axis moving module 21 is connected to the Y-axis moving module 22, and the movable end of the Y-axis moving module 22 is connected to the fixed base 30. The X-axis moving module 21 and the Y-axis moving module 22 respectively drive the laser measuring sensor 3 to move along the X-axis and Y-axis directions. With this configuration, the laser measuring sensor 3 can be aligned with different tooth surface positions of the worm gear to perform point-by-point or continuous scanning, thereby realizing comprehensive measurement of the worm gear.

[0041] like Figure 5 As shown, further, the sliding clamp 65 is provided with limiting blocks 652 on both sides, which are positioned and abut against the limiting groove 610. The limiting blocks 652 are used to restrict the sliding block from falling out of the limiting groove 610.

[0042] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
