Description

Technical Field

[0001] This invention belongs to the field of metallurgical machinery design and relates to an axial adjustment device, particularly a rotary shaft type axial movement adjustment device. Background Technology

[0002] In the field of profile steel production and processing, the axial displacement adjustment mechanism is a key component of profile steel production and processing equipment, and its performance and structure directly affect production efficiency and product quality. Currently, the axial displacement adjustment mechanisms used in my country's profile steel production and processing equipment are generally quite complex. This is not only reflected in the axial adjustment involving multiple devices, but also in the multifaceted nature of their structural design and transmission mechanisms. To achieve precise axial displacement, numerous transmission mechanisms often need to work together, which not only increases the manufacturing cost of the equipment but also significantly occupies production space, posing a considerable challenge to the layout and optimization of the production environment. Alternatively, manual offline adjustment is often required. This process is not only time-consuming and labor-intensive but also highly susceptible to human factors, making it difficult to guarantee the accuracy and consistency of the adjustment, thus affecting the processing precision and overall quality of the profile steel products.

[0003] In view of the above situation, the steel profile production and processing industry urgently needs a new type of axial displacement adjustment mechanism to solve the problems existing in the current technology. This is of great significance for improving the overall technical level and market competitiveness of my country's steel profile production and processing industry. This is not only an urgent need for technological innovation, but also an inevitable trend in industry development. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a rotary shaft type axial movement adjustment device that can adjust the axial position of all roller rings on the transmission shaft, and has a simple structure and small space occupation, so as to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A rotating shaft type axial movement adjustment device includes a drive shaft and a plurality of roller rings that are circumferentially fixed and axially slidably sleeved on the drive shaft, and each roller ring is provided with an arc-shaped bushing fixedly connected thereto. A worm gear assembly is provided at one end of the transmission shaft. The worm gear assembly includes a worm gear mounting seat and multiple worms rotatably mounted in the worm gear mounting seat. The worm gear mounting seat is coaxially arranged with the transmission shaft. The worms are arranged on the worm gear mounting seat in a circumferential direction, and their number corresponds one-to-one with the arc-shaped bushings. The arc-shaped bushings are provided with gear teeth that mesh with the worms, so as to adjust the axial position of the roller ring by rotating the worms.

[0006] Furthermore, an axial movement adjustment device is provided at one end of the drive shaft where the worm gear assembly is mounted. The axial movement adjustment device includes a telescopic rotation device and an adjustment motor. The telescopic rotation device is coaxially arranged with the worm gear mounting seat. The adjustment motor is connected to the telescopic rotation device and is driven by the worm gear. Under the drive of the telescopic rotation device, the adjustment motor performs circumferential motion around the telescopic rotation device and moves along the axial direction of the drive shaft, so that it can be driven to connect with multiple worm gears.

[0007] Furthermore, a mounting shaft is provided at one end of the telescopic rotating device near the worm gear mounting base to connect the telescopic rotating device to the worm gear mounting base.

[0008] Furthermore, there are two drive shafts, arranged vertically in the frame, with multiple roller rings mounted on the upper drive shaft forming an upper roller assembly, and multiple roller rings mounted on the lower drive shaft forming a lower roller assembly. An axial movement adjustment device and a worm gear assembly are provided at one end of each of the two drive shafts.

[0009] Furthermore, the upper roller assembly includes an upper roller system first roller ring, an upper roller system second roller ring, an upper roller system third roller ring, an upper roller system fourth roller ring, an upper roller system fifth roller ring, and an upper roller system sixth roller ring, which are installed on the drive shaft in the order of roller rings, and the worm gear mounting seat has 6 worms.

[0010] Furthermore, the arc-shaped bushings in the first, second, third, fourth, fifth, and sixth roller rings of the upper roller system are radially spliced ​​into a circular bushing, which is then fitted onto the drive shaft. One of the arc-shaped bushings is keyed to the drive shaft, so that the drive shaft is circumferentially fixedly connected to each roller ring mounted thereon, and axially slidably connected.

[0011] Furthermore, the roller rings in the lower roller assembly include a first roller ring, a second roller ring, a third roller ring, and a fourth roller ring installed on the drive shaft in the order of roller rings, and the worm gear mounting seat contains four worm gears.

[0012] Furthermore, the arc-shaped bushings in the first, second, third, and fourth roller rings of the lower roller system are radially spliced ​​into a circular bushing, which is then fitted onto the drive shaft. One of the arc-shaped bushings is keyed to the drive shaft, so that the drive shaft is circumferentially fixedly connected to each roller ring mounted thereon, and axially slidably connected.

[0013] Furthermore, the worm gear assembly is arranged at one end of the drive shaft near the operating side.

[0014] The beneficial effects of this invention are as follows: The present invention provides a rotary shaft type axial movement adjustment device, which uses a roller ring with an arc-shaped bushing and a transmission shaft to form a roller system. At one end of the transmission shaft, the gear teeth on the arc-shaped bushing and the worm gear cooperate to form a worm gear structure, thereby adjusting the axial position of the roller ring by rotating the worm gear. The axial adjustment is highly accurate and easy to adjust, and the structure is simple and compact. Secondly, in this invention, the number of worm gears corresponds one-to-one with the number of arc-shaped bushings. However, by using a telescopic rotation device in conjunction with the structure of the adjusting motor, the adjusting motor can make circular motion along the axis of the telescopic rotation device and telescopic motion along its axial direction. This allows one adjusting motor to intermittently drive multiple worm gears, which saves a lot of space and reduces the number of driving devices compared to traditional axial adjustment devices.

The worm gear mounting base 402 is coaxially mounted on one end of the transmission shaft 6, and the worm gear 403 is respectively mounted in the mounting holes of the worm gear mounting base 402. The inner surface of one end of the arc-shaped bushing 7 in the upper roller system (first roller ring 102, second roller ring 103, third roller ring 104, fourth roller ring 105, fifth roller ring 106, sixth roller ring 107, first roller ring 202, second roller ring 203, third roller ring 204, and fourth roller ring 205) is provided with gear teeth 8 that mesh with the worm gear 403 to form a worm gear structure; the head of the adjusting motor 304 can be coupled with the end of the worm gear 403 for rotation, and the number of worm gears 403 is equal to the number of adjusting roller rings required.

[0023] Specifically, both the sixth roller ring 107 of the upper roller system and the fourth roller ring 205 of the lower roller system are provided with keyways or keys to serve as roller rings that are keyed to the drive shaft 6 in the upper roller system assembly 1 and the lower roller system assembly 2.

[0024] The drive shaft 6 has a central protrusion at one end near the worm gear assembly 4, and the worm gear mounting seat 402 is sleeved on the central protrusion so that the worm gear mounting seat 402, the drive shaft, the mounting shaft and the telescopic rotation device are arranged coaxially.

[0025] The working principle of the axial movement adjustment device of the rotating shaft in this embodiment is as follows: the roller system of the axial movement adjustment device is assembled from several roller rings with arc-shaped bushings. The arc-shaped bushings are formed by radially dividing a complete circular bushing. A worm gear matching the gear teeth on the arc-shaped bushing is set at one end of the transmission shaft, thereby forming a worm gear mechanism. The worm gear is connected to the adjustment motor in the axial movement adjustment device, and the axial movement of the roller ring is achieved by the rotation of the adjustment motor.

[0026] In this embodiment, the axial movement adjustment device 3 and the worm gear assembly 4 are both arranged on the operating side of the transmission shaft 6 to avoid interference with the power device on the transmission side of the transmission shaft 6.

[0027] Specifically, the worm gear assembly 4 used for adjusting the upper roller system assembly 1 has 6 worm gears 403 installed in the worm gear mounting seat 402, which respectively correspond to the bushings in the first roller ring 102, the second roller ring 103, the third roller ring 104, the fourth roller ring 105, the fifth roller ring 106, and the sixth roller ring 107 of the upper roller system; Four worms 403 are installed in the worm mounting seat 402 of the worm gear assembly 4 for adjusting the lower roller system assembly 2, respectively corresponding to the bushings in the first roller ring 202, the second roller ring 203, the third roller ring 204, and the fourth roller ring 205 of the lower roller system. The worms in the worm mounting seat 402 are evenly arranged along the circumferential direction on the worm mounting seat 402. Each worm mounting seat 402 corresponds to an adjusting motor 304. The telescopic rotation device 303 and the mounting shaft 302 installed at the end of the telescopic rotation device 303 are arranged coaxially with the worm mounting seat 402. The adjusting motor 304 is connected to the circumference of the telescopic rotation device 303 and performs circumferential rotation and telescopic movement under the action of the telescopic rotation device 303, thereby intermittently driving multiple worms through one adjusting motor 304.

[0028] Specifically, a polyhedral protrusion is provided at one end of the worm gear 403 near the adjusting motor 304, and a groove that mates with the polyhedral protrusion is provided at the output end of the adjusting motor 304 to transmit power.

[0029] After adjusting one roller ring, if axial adjustment of other roller rings is required, the adjusting motor 304 needs to be rotated in a uniform circumferential direction under the action of the telescopic rotating device 303. Before the uniform circumferential rotation, the adjusting motor 304 needs to be moved away from the worm 403 under the action of the telescopic rotating device 303, thereby cutting off the connection between the worm 403 and the adjusting motor 304. After rotating to the correct position, the adjusting motor 304 is driven by the telescopic rotating device 303 to move closer to the worm 403 to re-establish the power connection.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
