Description

Technical Field

[0001] The utility model relates to a long shaft supporting tool, belonging to the field of long shaft processing. Background Art

[0002] Long shafts, as key components for transmitting torque and motion, are widely used in various types of machinery. During machining, long shafts (or tubes) often need to be processed, such as screws. Because screws are very long, they are clamped at either or one end during machining, leaving one end or the middle of the screw suspended. This causes the screw end to drop and bend due to gravity, which affects machining accuracy. Furthermore, the centrifugal force generated by the lathe spindle rotating the long shaft during machining causes the long shaft to oscillate significantly, often resulting in vibration, noise, and jamming, which not only reduces machining quality but also poses a safety hazard. To meet the support requirements for long shafts, most machines require additional supports to support the long shaft and prevent it from being suspended. However, long shafts come in a wide variety of sizes and diameters. After the long shaft is positioned by the machine's chuck or center, the required support height varies depending on the diameter. Fixed-height supports are poorly adaptable during machining and are difficult to meet the support requirements for long shafts of varying diameters. Utility Model Content

[0003] The long shaft support tooling provided by the utility model avoids the long shaft from being suspended in the process of processing, prevents the long shaft from bending and deforming, improves the processing quality and processing safety, and can adaptively adjust the height of the supporting roller according to the diameter of the long shaft to meet the support requirements of long shafts of various specifications, and is highly practical.

[0015] The following combination Figures 1 and 2 The embodiments of the present utility model are described in detail.

[0016] The long axis support tooling includes a base plate 1 and a support assembly 2 installed on the base plate 1 to support the long axis, and is characterized in that: the support assembly 2 includes a support plate 3 arranged parallel to the base plate 1, a support roller 4 rotatably installed on the support plate 3, a height adjustment bolt 5 for adjusting the height of the support plate 3, a multi-column support plate 6 supporting the support plate 3 and a guide assembly 7 for guiding the lifting and lowering of the support plate 3, the support height of the multi-column support plate 6 is adjustable, the number of support rollers 4 is two, and the two support rollers 4 are arranged side by side, and the long axis is supported between the two support rollers 4.

[0017] The above-mentioned long shaft support tooling is used by installing the base plate 1 on the machine tool for processing the long shaft, and supporting the long shaft with the supporting roller 4, which is installed on the supporting plate 3. The supporting plate 3 is adjusted in height by adjusting the bolt 5, and is lifted and lowered by the guide assembly 7 to ensure that the supporting plate 3 is only lifted and lowered without tilting. After adjustment, the supporting plate 3 is supported by the multi-column support plate 6 to ensure the stability of the supporting plate 3. The long shaft is supported between the two supporting rollers 4 to avoid the long shaft from being suspended during the processing, to prevent the long shaft from bending and deforming, and to improve the processing quality; the two supporting rollers 4 not only support the long shaft, but also limit the shaking of the long shaft during the processing, reduce the probability of jitter, abnormal noise and jamming of the long shaft during the processing, and improve the processing safety of the long shaft; the height of the supporting plate 3 can be adjusted by adjusting the bolt 5, and the multi-column support plate 6 can adjust the support height, so as to realize the adjustment of the height of the supporting roller 4, so as to adapt the height of the supporting roller to the diameter of the long shaft, meet the support requirements of long shafts of various specifications, and have high practicality.

[0018] The guide assembly 7 includes a linear bearing 71 fixed to the base plate 1 and a guide shaft 72 fixed to the bottom of the support plate 3 and cooperating with the linear bearing 71. The linear bearings 71 are arranged in a rectangular shape on the base plate 1. The linear bearings 71 and the guide shaft 72 cooperate to guide the lifting and lowering of the support plate 3, preventing the support plate 3 from tilting, ensuring that the support plate 3 can only be raised and lowered, and will not tilt.

[0019] The height adjustment bolt 5 is rotatably mounted on the base plate 1 and threadedly extends through the support plate 3. The height adjustment bolt 3 and the multi-column support plate 6 are located on opposite sides of the support plate 3. Rotation of the support plate 3 causes the support plate 3 to rise and fall to adjust its height. Once the support plate 3 is adjusted into position, it is supported by the multi-column support plate 6, ensuring the stability of the support plate 3 and, consequently, the support roller 4, enabling it to effectively support the long shaft. Lightweight and high-strength stainless steel rollers are selected as the support rollers 4 to reduce wear and extend their service life.

[0020] The multi-column support plate 6 includes a turntable 61 rotatably mounted on the bottom plate, and standard columns 62 of varying heights mounted on the top surface of the turntable 61. The standard columns 62 are evenly distributed along the circumference of the turntable 61, and the support plate 3 abuts against one of the standard columns 62. The standard columns 62 are support columns with standard heights set according to the diameter of the long shaft. Each standard column 62 corresponds to a long shaft of a certain diameter. When a long shaft of a certain diameter needs to be supported, the height adjustment bolt 5 is rotated to move the support plate 3 upward, and then the turntable 62 is rotated according to the diameter of the long shaft to rotate the corresponding standard column 62 to a position aligned with the support plate 3. The height adjustment bolt 5 is then rotated to lower the support plate 3 so that the support plate abuts against the standard columns 62. The support roller 4 is supported at the corresponding height, and the long shaft is properly supported on the support roller 4 after being assembled in place.

[0021] The bottom surface of the support plate 3 has a mating pin 31 that engages with a standard post 62. The top surface of the standard post 62 has a groove 63 that engages with the mating pin 31. The mating pin 31 extends into the groove 63 and abuts against the standard post 62. The groove 63 guides the mating pin 31 so that it can be inserted into the groove 63 and abut against the standard post 62. The mating between the groove 63 and the mating pin 31 also ensures the stability of the support plate 3, thereby reducing vibration of the support roller 4 and improving structural stability.

[0022] The turntable 61 is a DD motor. Taking advantage of its small size and high rotation angle accuracy, the DD motor is mounted on the plate 1, and the standard column 62 is mounted on the DD motor. The standard column 62 is accurately aligned with the matching pin 31 through the rotation of the DD motor.

[0023] The above is a complete description of the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the embodiments described are only part of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
