Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transmission shaft production, in particular to a spline shaft oxide scale cleaning device. Background Art
[0002] Spline shafts have the same function as flat keys, semi-circular keys, and wedge keys, which are all used to transmit mechanical torque. There are longitudinal keyways on the surface of the shaft. Spline shafts are divided into two categories: rectangular spline shafts and involute spline shafts. Rectangular spline shafts are widely used. Rectangular spline shafts are usually used in aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery, and general mechanical transmission devices.
[0003] The static torque and fatigue endurance that a spline shaft can withstand are the most important performance indicators. To achieve these performance indicators, the spline shaft must be subjected to high-frequency quenching. However, after high-frequency quenching, the spline shaft surface will inevitably have a large amount of oxide scale due to high-temperature heating. This oxide scale must be completely cleaned before the spline shaft surface can be painted or other post-processing. Otherwise, the coating will have insufficient adhesion and affect corrosion resistance. The oxide scale remaining on the spline shaft splines will also fall off during transmission, causing accelerated wear of the splines and, in severe cases, preventing normal transmission.
[0004] Currently, commonly used cleaning processes include sandblasting, chemical cleaning, and polishing. Sandblasting is inefficient and produces significant noise and dust. Chemicals pose a serious environmental risk, requiring a comprehensive treatment device to meet emission standards, resulting in high costs. Polishing, on the other hand, is highly efficient, but commonly used polishing equipment on the market is typically only suitable for products with simple, contoured exteriors, such as round steel. It is incapable of fully cleaning the splines on spline shafts, let alone cleaning the splines on batches of spline shafts. Utility Model Content

[0014] The beneficial effects of the utility model are:

[0027] The utility model provides a spline shaft oxide scale cleaning device, comprising: a body 1; a workbench 2, which is mounted on the upper end surface of the body 1; a three-jaw chuck 3; a top assembly 4, which includes a top 5, the central axis of the three-jaw chuck 3 coincides with the central axis of the top 5, and the three-jaw chuck 3 and the top 5 are respectively mounted on the left and right ends of the upper end surface of the workbench 2; a first driving member 9, which is mounted on the workbench 2 and driven by the three-jaw chuck 3; a cleaning mechanism 16, which comprises a mounting plate 10, a second driving member, a rotating shaft 12 and a wire wheel 13, the mounting plate 10 being arranged at the rear end of the upper end surface of the body 1, the second driving member being mounted on the mounting plate 10 and driven by the rotating shaft 12, the rotating shaft 12 being arranged below the second driving member, the rotating shaft 12 being arranged in a vertical direction, and the outer sleeve of the wire wheel 13 being fixed to the bottom of the rotating shaft 12.
[0028] When the cam 17 is in the working state, the cam 13 is in the working state, and the cam 13 is in the working state, so that the cam 13 is in the working state, and the cam 13 is in the working state, so that the cam 13 is in the working state, and the cam 13 is in the working state, so that the cam 13 is in the working state, and the cam 13 is in the working state, so that the cam 13 is in the working state, and the cam 13 is in the working state, so that the cam 13 is in the working state, and the cam 13 is in the working state, so that the cam 13 is in the working state,
[0029] The position of the spline on the spline shaft 17 varies depending on different usage scenarios. For example, the spline can be set at one end of the spline shaft 17. When the spline is set at one end of the spline shaft 17, when the spline shaft 17 is clamped, the optical axis end of the spline shaft 17 is usually clamped by a three-jaw chuck 3, and then the spline end of the spline shaft 17 is tightened by the top 5.
[0030] In order to ensure the squeezing force between the wire wheel 13 and the spline while preventing the wire wheel 13 from obstructing the clamping of the spline shaft 17, as a preferred embodiment, the further improvement of the present invention is that the second drive member is slidably mounted on the mounting plate 10 in the vertical direction, and the cleaning mechanism 16 also includes: a third drive member 14, the third drive member 14 is fixedly mounted on the top of the mounting plate 10, and the third drive member 14 drives the second drive member to slide up and down along the mounting plate 10.
[0031] Before installing the spline shaft 17, the second driving member is driven upward by the third driving member 14, so that the wire wheel 13 moves upward until the wire wheel 13 moves to a sufficiently high position, and then the spline shaft 17 is clamped. After the spline shaft 17 is clamped, the third driving member 14 drives the second driving member to move downward, and the wire wheel 13 drops to the working position. Since the wire wheel 13 is removed before the spline shaft 17 is clamped, the setting of the wire wheel 13 will not hinder the clamping of the spline shaft 17. Even if the extrusion force between the wire wheel 13 and the spline is relatively large during operation, it will not hinder the clamping of the spline shaft 17. When there is sufficient extrusion force between the wire wheel 13 and the bottom of the spline keyway, the spline can be cleaned more cleanly.
[0032] The spline shaft oxide scale cleaning device also includes a fourth drive member, which drives the workbench 2 to move relative to the mounting plate 10 along the left-right direction of the fuselage 1. The workbench 2 and the mounting plate 10 can move relative to each other along the left-right direction of the fuselage 1, and the wire wheel 13 and the spline can move relative to each other along the left-right direction of the fuselage 1, which can better clean the spline along its length.
[0033] The top assembly 4 also includes a mounting base 6, on which the top 5 is mounted. The mounting base 6 can be moved left and right along the workbench 2 and locked. The specific structure and working principle of the top assembly 4 can be referred to the spline shaft milling machine, and will not be repeated here.
[0034] The first driving member 9 includes a first motor 8 and a first reduction gearbox 7. The first reduction gearbox 7 is fixedly mounted on the upper end surface of the workbench 2. The first motor 8 is mounted on the upper end surface of the first reduction gearbox 7. The first motor 8, the first reduction gearbox 7 and the three-jaw chuck 3 are sequentially driven and connected. The second driving member includes a second motor 15 and a second reduction gearbox 11. The second reduction gearbox 11 is mounted on the mounting plate 10. The second motor 15 is mounted on the upper end surface of the second reduction gearbox 11. The second motor 15, the second reduction gearbox 11 and the rotating shaft 12 are sequentially driven and connected. The fourth driving member includes a third motor, a lead screw and a slider. The third motor and the lead screw are respectively mounted on the machine body 1. The upper end surface of the slider is fixedly connected to the lower end surface of the workbench 2. The third motor, the lead screw and the slider are sequentially driven and connected. The specific structure and working principle of the first driving member 9, the second driving member and the fourth driving member can be referred to the spline shaft milling machine, and will not be repeated here.
[0035] The second reduction gearbox 11 is slidably connected to the mounting plate 10 in the vertical direction. The third driving member 14 is a hydraulic cylinder. The side of the hydraulic cylinder is fixedly connected to the top of the mounting plate 10. The piston rod of the hydraulic cylinder is fixedly connected to the top of the second reduction gearbox 11. The piston rod of the hydraulic cylinder is arranged in the vertical direction.
[0036] In actual production and manufacturing, the utility model can be obtained by modifying a vertical spline shaft milling machine. The main improvement is that the milling cutter of the milling cutter assembly is replaced with a wire wheel 13, and the milling cutter assembly is made into a liftable structure. After the modification, the vertical spline shaft milling machine no longer processes splines, but is specifically used to clean the oxide scale of the splines on the spline shaft 17.
[0037] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
