Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to tooling for heavy-duty hydraulic base support lathes. Background Technology

[0002] Machine tool processing refers to the cutting and other machining operations performed on workpieces using machine tools to achieve the desired shape, size, and surface quality. There are many types of machine tools. For example, lathes are mainly used to machine the surfaces of rotating bodies, such as turning cylinders, cones, and rollers.

[0003] When machining rollers, existing machine tools mount the rollers on a lathe, rotating them while performing the machining. Different weight rollers require lathes of different sizes. A typical lathe can only mount rollers weighing up to 15 tons. For heavier rollers, a larger lathe is required, which drastically increases the machining cost. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a heavy-duty hydraulic base support lathe tooling.

[0005] According to the present invention, the heavy-duty hydraulic base support lathe tooling includes at least one bracket and at least two rollers rotatably connected to a single bracket. The at least two rollers are distributed along the extension direction of the bracket to support the roller shaft to be processed in the radial direction. A telescopic mechanism is connected to one end of the bracket away from the rollers. The telescopic mechanism is slidably connected to a support platform at one end away from the bracket, so that the bracket and the rollers can be displaced along the axial direction of the roller shaft to be processed.

[0006] The purpose of this setup is to provide support for heavy rollers and assist in their rotation, allowing for the processing of larger tonnage products using a standard lathe, thereby reducing processing costs.

[0007] In practical use, multiple lathe fixtures can be set at the lower end of the roller shaft to be processed, so that the multiple fixtures are arranged along the axial direction of the roller shaft. The fixtures' brackets and rollers support the roller shaft. The rollers can also rotate with the rotation of the roller shaft, that is, the sliding friction between the roller shaft and the fixtures is converted into rolling friction, thereby avoiding the roller shaft from running poorly.

[0008] The telescopic mechanism can accommodate rollers of different diameters, thus ensuring that the rollers always support the rollers.

[0009] Furthermore, the sliding connection between the telescopic mechanism and the support platform can adjust the position of the bracket and rollers relative to the roller shaft, thereby adapting to roller shafts of different lengths.

[0010] In some examples of this utility model, the bracket includes at least two oppositely arranged plates and a crossbeam connecting the adjacent plates. Each plate has at least two roller grooves, and the rollers are mounted in the corresponding roller grooves on the two adjacent plates.

[0011] The purpose of this setup is that each fixture includes at least two plates, which support the rollers and ensure the stability of the rollers, preventing them from detaching from the plates during operation. In addition, each fixture includes at least two rollers, which ensures the stability of the support for the roller shaft and prevents the roller shaft from detaching from the fixture during operation.

[0012] In some examples of this utility model, the recess on the plate located between adjacent rollers is a clearance groove;

[0013] The purpose of this design is to allow clearance grooves to avoid interference between the roller shafts of adjacent rollers and the workpiece during rotation.

[0014] In some examples of this utility model, a reinforcing plate is connected to one side of each plate; the reinforcing plate is used to increase the support performance of the plate and facilitate the deformation of the plate during long-term operation.

[0015] In some examples of this utility model, the telescopic mechanism is a hydraulic cylinder, which includes a cylinder barrel and a piston rod, with the piston rod extending outside the cylinder barrel and connecting to the plate.

[0016] The purpose of setting the telescopic mechanism as a hydraulic cylinder is that the supporting effect of the hydraulic cylinder on the bracket is flexible rather than rigid. By controlling the oil supply, the support position and support force can be continuously adjusted. The support force can be adjusted in a timely manner according to the condition of the product, that is, the lifting force can be adjusted according to different weights, so that the longitudinal bearing force of the machine tool spindle is maintained within the ideal range, thereby reducing machine tool wear and improving workpiece accuracy.

[0017] In some examples of this utility model, a slider is connected to the end of the cylinder away from the piston rod, and the slider is slidably connected to the support platform; when the slider undergoes linear displacement relative to the support platform, the support position of the tooling can be adjusted.

[0018] In some examples of this utility model, the hydraulic cylinder passes through the slider, and a stop is formed in the middle of the hydraulic cylinder to abut against the slider. The stop is used to prevent the hydraulic cylinder from moving along the slider.

[0019] In some examples of this utility model, a slide rail groove that can extend along the roller shaft is formed on the support platform, a shoulder is formed at the upper end of the slide rail groove, the shoulder extends along the slide rail groove, and a slide groove corresponding to the shoulder is formed on the slider.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0038] The following is for reference. Figures 1 to 6 The illustration depicts a heavy-duty hydraulic base support lathe tooling according to an embodiment of the present invention.

[0039] For details, please see the appendix. Figure 1This is a schematic diagram of the structure of a heavy-duty hydraulic base support lathe tooling. The lathe tooling includes a support 1 and two rollers 2 rotatably connected to the support 1. The two rollers 2 are distributed along the extension direction of the support 1 to support the roller a to be processed in the radial direction.

[0040] The extension direction of bracket 1 here refers to Figure 1 The direction F shown means that the two rollers 2 are not distributed along the axial direction of the roller shaft a, but need to be distributed in the circumferential direction of the roller shaft a to provide circumferential support for the roller shaft a.

[0041] Please continue reading the appendix. Figure 1 The end of the support 1 away from the roller 2 is connected to the telescopic mechanism 3. The telescopic mechanism 3 makes the distance between the support 4 and the support 1 adjustable, so as to accommodate rollers a of different diameters.

[0042] Please continue reading the appendix. Figure 1 The end of the telescopic mechanism 3 away from the support 1 is slidably connected to the support 4, so that the support 1 and the roller 2 can be displaced along the axial direction of the roller a to be processed. In this way, the telescopic mechanism 3 can be translated relative to the support 4, which can drive the support 1 and the roller 2 to be adjusted along the axial direction of the roller a, thereby adapting to rollers a of different lengths.

[0043] Please see the appendix Figure 2 The top view of the bracket 1 shows that the bracket 1 includes two oppositely arranged plates 11 and a crossbeam 12 connecting the two plates 11. There are two crossbeams 12, which are spaced apart between the two plates 11, so that the roller 2 can be mounted between the two plates 11, and a gap is formed between the two crossbeams 12, at which the output end of the telescopic mechanism 3 can be inserted.

[0044] Please continue reading the appendix. Figure 2 and attached Figure 3 , attached Figure 3 This is a front view of the bracket 1. Each plate 11 has two roller grooves 111. The roller grooves 111 on two plates 11 are in a one-to-one correspondence, so that a roller 2 can be installed between the corresponding roller grooves 111 on two plates 11. A total of two rollers 2 are installed in the four roller grooves 111. Specifically, the shafts 21 of the rollers are respectively installed on the corresponding roller grooves 111, forming as shown in the attached figure. Figure 1 The situation shown.

[0045] Please continue reading the appendix. Figure 2 and attached Figure 3 The recessed part 11 between the two rollers 2 is a relief groove 112. The relief groove 112 is arc-shaped and corresponds to the circumferential surface of the roller a, so as to avoid the circumferential surface of the roller a.

[0046] In other embodiments, the clearance groove 112 may also be of other shapes.

[0047] Please continue reading the appendix. Figure 2 On the opposite side of the two plates 11, each plate 11 is connected to a reinforcing plate 13. The function of the reinforcing plate 13 is to increase the load-bearing capacity of the plate 11.

[0048] Please see the appendix Figure 4 The front view of the reinforcing plate 13 shows that the upper end of the reinforcing plate 13 is also set in the shape of an avoidance groove 112 to avoid interference with the roller a.

[0049] Please continue reading the appendix. Figure 1 The telescopic mechanism 3 is a hydraulic cylinder, which includes a cylinder barrel 31 and a piston rod 32. The piston rod 32 extends to the outside of the cylinder barrel 31 and connects to the plate 11.

[0050] Specifically, the cylinder 31 includes a cylinder body 311, an upper end cover 312, and a lower end cover 313. The upper end cover 312 and the lower end cover 313 are fixed and sealed to the cylinder body 31. One end of the piston rod 32 is placed inside the cylinder body 311, and a sealing ring 33 is provided between it and the inner wall of the cylinder body 311. The other end extends through the upper end cover 312 to the outside of the cylinder body 311 and is connected to the bracket 1.

[0051] Please see the appendix Figure 1 , Figures 3 to 5 picture, Figure 5 The piston rod 32 is shown in the front view. The end of the piston rod 32 that extends out of the cylinder 311 forms a first through hole 321, the plate 11 forms a second through hole 113, and the reinforcing plate 13 forms a third through hole 131.

[0052] The piston rod 32 is connected to the bracket 1 by extending one end of the piston rod 32 between the two crossbeams 12, and passing the shaft pin 14 through the first through hole 321, the second through hole 113, and the third through hole 131 and welding it.

[0053] Please continue reading the appendix. Figure 1 An oil inlet 314 is also provided on the side of the cylinder body 311 near the lower end cover 313. When the piston rod 32 needs to be adjusted, hydraulic oil is introduced into the cylinder body 311 through the oil inlet 314, forming a heavy-duty hydraulic base support lathe tooling as follows: Figure 6 The state shown is sufficient.

[0054] Please continue reading the appendix. Figure 1 The end of the cylinder 31 away from the piston rod 32 is connected to a slider 5, which is slidably connected to the support 4.

[0055] Specifically, the hydraulic cylinder passes through the slider 5, and a stop 315 is formed in the middle of the hydraulic cylinder to abut against the slider 5. The stop 315 is an annular protrusion integrally formed with the cylinder body 311.

[0056] Please continue reading the appendix. Figure 1 A slide rail groove 41 that can extend along the roller shaft a is formed on the support 4. A shoulder 411 is formed at the upper end of the slide rail groove 41. The shoulder 411 extends along the slide rail groove 41. A slide groove 51 corresponding to the shoulder 411 is formed on the slider 5.
