Description

Technical Field

[0001] This utility model relates to the field of gear measurement technology, specifically to a device for measuring the span of gears in a plastic manufacturing machine. Background Technology

[0002] In the manufacturing process of plastic forming machines, gears, as key transmission components, have a significant impact on the operational stability and product quality of the machine. The span distance is one of the important parameters for measuring gear precision; accurate measurement of the span distance is crucial for ensuring the machining quality and assembly accuracy of the gears.

[0003] Currently, existing gear span measurement devices have many problems when measuring the gears under test. On the one hand, the gear limiting and positioning process is cumbersome, requiring operators to spend a lot of time and effort on adjustments, resulting in low measurement efficiency; on the other hand, inaccurate positioning can easily lead to measurement errors, failing to meet the requirements of high-precision measurement.

A rotating disk is rotatably mounted on the lower surface of the support disk. Push grooves are inclinedly opened on the surface of the rotating disk at positions corresponding to the multiple fixed rods. The lower end of the fixed rod extends into the inner side of the corresponding push groove. A limiting mechanism is provided on the lower surface of the support disk to restrict the rotation of the rotating disk.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a device for measuring the span of gears in a plastic forming machine.

[0026] Example 1

[0027] Reference Figure 1-5 A gear span measuring device for a plastic manufacturing machine includes a base 1 and sliders 2. A groove is formed on the upper surface of the base 1, and a bidirectional lead screw 10 is rotatably mounted inside the groove. Two sliders 2 are threaded onto both ends of the bidirectional lead screw 10. A handle is fixedly attached to one end of the bidirectional lead screw 10 for easy rotation. Measuring rods 3 are fixedly mounted on the upper sides of both sliders 2. Scale lines 4 are printed on both ends of the front side of the base 1. Indicating arrows 5 are fixedly mounted on the front side of the sliders 2, pointing to the corresponding scale lines 4 for easy observation of the slider 2's position. A horizontal plate 11 is fixedly mounted in the middle of the upper side of the groove, and the upper surface of the horizontal plate 11 is fixedly... A support plate is fixedly provided, and a support rod 6 is fixedly provided on the upper surface of the support plate. A support disk 7 is fixedly provided at the upper end of the support rod 6. Multiple strip-shaped openings are arranged in a ring array around the center of the support disk 7 on the upper surface. Movable blocks 16 are slidably provided inside the multiple strip-shaped openings. A fixed rod 9 is fixedly sleeved in the middle of the movable block 16. A rotating disk 8 is rotatably provided on the lower surface of the support disk 7. Push grooves 17 are inclinedly provided on the surface of the rotating disk 8 at positions corresponding to the multiple fixed rods 9. The lower end of the fixed rod 9 extends to the inner side of the corresponding push groove 17. A limiting mechanism is provided on the lower surface of the support disk 7 to restrict the rotation of the rotating disk 8.

[0028] Example 2

[0029] Reference Figure 1-5 The limiting mechanism includes an arc-shaped clamping plate 15 and a threaded rod 13. Side plates 12 are fixedly provided on both sides of the lower surface of the support plate 7. A threaded hole is opened in the middle of the side plate 12. The threaded rod 13 is threaded into the inside of the threaded hole. The arc-shaped clamping plate 15 is abutted against the side wall of the rotating plate 8. One end of the threaded rod 13 is rotatably connected to the arc-shaped clamping plate 15.

[0030] Example 3

[0031] Reference Figure 1-5 The side plate 12 has through holes on both sides of the threaded hole. A limit rod is slidably installed inside the through hole. One end of the limit rod is fixedly connected to the arc-shaped clamp 15, so that the arc-shaped clamp 15 will not rotate with the threaded rod 13, that is, it can move stably.

[0032] Example 4

[0033] Reference Figure 1-5 A crossbar 14 is provided parallel to the lower end of the bidirectional lead screw 10. Both ends of the crossbar 14 are fixedly connected to the inner wall of the corresponding slide groove. The lower sides of the two sliders 2 are movably sleeved with the crossbar 14, so that the sliders 2 will not rotate with the bidirectional lead screw 10, that is, they can slide stably along the bidirectional lead screw 10.

[0034] In this invention, during use, the gear to be tested is placed on the support plate 7. Rotating the rotating plate 8 causes the push groove 17 to push the fixed rod 9, which in turn moves the movable block 16, causing multiple fixed rods 9 to contact the inner ring of the gear, thus achieving gear positioning and limiting. Tightening the threaded rod 13 clamps the rotating plate 8 through the arc-shaped clamping plate 15 to complete the limiting and locking. Then, rotating the handle of the bidirectional lead screw 10, according to the scale line 4 and the indicator arrow 5, causes the measuring rods 3 on both sides to move synchronously until they contact the gear tooth surface, allowing for the measurement of the distance between the rods. After measurement, the operation is reversed to release the limiting mechanism, retract the measuring rods, and remove the gear, completing one measurement cycle.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
