Description

Technical Field

[0001] This utility model relates to the field of shaft machining technology, specifically a support device for long shaft machining. Background Technology

[0002] A shaft is a cylindrical component in machinery used to transmit power and motion. It is usually a metal rod with varying diameters at different sections. Its core function is to support rotating parts (such as gears and pulleys) and transmit torque or bending moment. Depending on its application, shafts can be classified into rotating shafts (which bear both bending moment and torque), spindles (which bear only bending moment), and transmission shafts (which primarily transmit torque).

[0003] When a long shaft is being machined, its tail end tends to sag under its own weight and cutting force, resulting in a wavy surface after cutting. Furthermore, the long shaft has poor rigidity, which can easily induce vibrations under high-speed cutting, leading to surface chatter marks. In addition, the tool wear is accelerated, and even cutting chatter can occur, causing the machining to be interrupted. Therefore, a support device for machining long shafts is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a support device for machining long shafts, including a machining table. Two support seats arranged in parallel are fixedly installed on the surface of the machining table, and the support seats are used to support the long shaft. A moving component is provided on the surface of the machining table, and a movable seat is provided at the moving end of the moving component. The movable seat carries the tail end of the long shaft. A driving component for driving the movable seat to move axially is also provided on the machining table.

[0005] Furthermore, the support base includes a pad, and the pad is fixedly installed on the table surface. Two support plates are welded to the side of the pad away from the table surface, and a V-shaped groove is opened on the side of the support plate away from the pad. Two mounting plates are also provided between the two support plates, and rollers are rotatably connected between the mounting plates and the pad. The two rollers are respectively located on both sides of the V-shaped groove.

[0006] Furthermore, the moving component includes two linear slide rails, both of which are fixedly installed on the processing table surface. Sliders are slidably connected to both linear slide rails, and both sliders are fixedly connected to the movable seat.

[0007] Furthermore, the drive assembly includes a clearance hole, the processing table surface has a clearance hole located between two linear slide rails, and a fixed plate located below the clearance hole is fixedly installed on the processing table. A drive motor is fixedly installed on the surface of the fixed plate, and a lead screw is provided at the output end of the drive motor. A support is also provided on the surface of the fixed plate, and the lead screw is rotatably connected to the support. A lead screw slider is threadedly connected to the outside of the lead screw, and a connecting plate is provided between the lead screw slider and the movable seat.

[0008] Furthermore, a stop plate is provided at one end of the movable seat.

[0009] Furthermore, leveling feet are provided at the four corners of the bottom of the processing table.

[0010] The beneficial effects of this utility model are: by setting a support base, and combining the V-groove on the support base with the roller, a stable three-point support structure (two support bases + movable base) is formed, which effectively disperses the weight of the long shaft and the cutting force, avoids the tail end sagging problem caused by the traditional two-center clamping, and at the same time, the drive component controls the axial movement of the movable base, which can also realize the feeding of the long shaft.

Therefore, they should not be construed as limitations on this utility model.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] In the embodiments, by Figure 1-2 A support device for machining long shafts is provided, comprising a machining table 1, on which two support seats 2 arranged in parallel are fixedly installed, and the support seats 2 are used to support the long shaft. A moving component 3 is provided on the surface of the machining table 1, and a movable seat 4 is provided at the moving end of the moving component 3. The movable seat 4 carries the tail end of the long shaft. A driving component 5 is also provided on the machining table 1 for driving the movable seat 4 to move axially. The movable seat 4 has the same structural principle as the support seats 2, so it will not be described again.

[0017] Reference Figure 1-2 The support base 2 includes a pad 21. The pad 21 is fixedly installed on the table surface of the processing table 1. Two support plates 22 are welded to the side of the pad 21 away from the processing table 1. The side of the support plate 22 away from the pad 21 is provided with a V-groove 23. Two mounting plates 24 are also provided between the two support plates 22. Rollers 25 are rotatably connected between the mounting plates 24 and the pad 21. The two rollers 25 are located on both sides of the V-groove 23. With the above structural setup, two support plates 22 are symmetrically welded to the pad block 21, and the V-shaped grooves 23 on their tops form a 120° angle. Automatic centering is achieved by utilizing geometric symmetry. When the long shaft is placed into the V-shaped groove 23, the groove wall and the surface of the long shaft make two-point contact. The line connecting the contact points makes an angle of 60° with the horizontal plane, forming a stable triangular support structure. The roller 25 converts friction into rolling friction, reducing friction by more than 90% and significantly reducing cutting vibration.

[0018] Reference Figure 1-2The movable component 3 includes two linear slide rails 31, both of which are fixedly installed on the table surface of the processing table 1. Each of the two linear slide rails 31 is slidably connected to a slider 32, and both sliders 32 are fixedly connected to the movable seat 4.

[0019] Reference Figure 1-2 The drive assembly 5 includes a clearance hole 51. The table surface of the processing table 1 has a clearance hole 51 located between two linear slide rails 31. A fixed plate 52 located below the clearance hole 51 is fixedly installed on the processing table 1. A drive motor 53 is fixedly installed on the surface of the fixed plate 52. A lead screw 54 is provided at the output end of the drive motor 53. A support 55 is also provided on the surface of the fixed plate 52. The lead screw 54 is rotatably connected to the support 55. A lead screw slider 56 is threadedly connected to the outside of the lead screw 54. A connecting plate 57 is provided between the lead screw slider 56 and the movable seat 4. A stop plate 6 is provided at one end of the movable seat 4. With the above structural setup, the clearance hole 51 on the table surface of the processing table 1 is located between the two linear slide rails 31, providing installation space for the drive assembly 5 below and avoiding interference with the processing table 1. The output end of the drive motor 53 is directly connected to the lead screw 54 through a coupling. Both ends of the lead screw 54 are supported by the support 55 (including angular contact ball bearings) to ensure rotational accuracy. The lead screw 54 and the lead screw slider 56 form a trapezoidal thread pair. The rotational force is converted into axial thrust through the helix angle of the thread, thereby pushing the movable seat to move axially and contacting the tail end of the long shaft of the abutment plate 6, thus realizing the loading of the long shaft.

[0020] Reference Figure 1-2 Among them, the processing table 1 is equipped with leveling feet 7 at the four corners of its bottom; With the above structural design, the leveling foot 7 consists of three parts: a threaded adjusting rod, a support pad, and a locking nut, which achieves sub-millimeter leveling of the processing table 1.
