[0021] As shown in Figures 1 and 2, an electric spindle repair and disassembly device includes a worktable 8, on which a positioning sleeve 13 is installed. Preferably, the boss surface of the electric spindle 9 is embedded in the insertion groove of the positioning sleeve 13. A through hole coaxial with the positioning sleeve 13 is opened in the center of the worktable 8, and the positioning sleeve 13 has a flange that rests on the worktable 8. The cylindrical body of the positioning sleeve 13 is fitted into the through hole. The positioning sleeve 13 also has a guide hole coaxial with the electric spindle 9. When the boss surface of the electric spindle 9 is embedded in the insertion groove of the positioning sleeve 13, the electric spindle 9 and the positioning sleeve 13 are coaxially installed. Upper columns 6 are installed in pairs on the upper surface of the worktable 8. The upper columns 6 stand at both ends of the worktable 8, and the tops of the two upper columns 6 are connected by a crossbeam 1. Further, the crossbeam 1 and the upper columns 6 are connected... The components are secured together by flange bolts. Specifically, screw holes are provided at the top of the upper column 6, and through holes for flange bolts are provided on the crossbeam 1. During installation, the through holes on the crossbeam 1 are aligned with the screw holes, and then the flange bolts are tightened. A jack 4 is mounted below the crossbeam 1 via a slide rail device 3. A press-fit transition head 12 is mounted on the telescopic shaft of the jack 4. In this embodiment, the bottom of the telescopic shaft of the jack 4 has an inner hole, which is inserted and connected to the upper end of the press-fit transition head. The slide rail device 3 is mounted on the crossbeam 1. In this embodiment, the slide rail device 3 includes a pair of slide rail frames 3.1, located on the front and rear sides of the crossbeam 1. A through hole is provided at the top of each slide rail frame 3.1. The top of the slide rail frame is connected to the jack 4 via a locking screw 3.3 installed in the through hole, and the top of the jack 4 abuts against the crossbeam 1. A manual hydraulic pump 7 is also installed on the top. The tops of the two slide rail frames 3.1 are connected by a shaft. Rollers 3.2 are rotatably mounted on the shaft. Rollers 3.2 travel on the upper end face of the crossbeam 1. Preferably, the through hole is an oblong hole. During installation, the position of the locking screw 3.3 in the oblong hole can be adjusted to adjust the axial height of the jack 4, thereby ensuring that the top of the jack 4 abuts against the crossbeam 1. During use, the lateral position of the slide rail device 3 can be adjusted by the rollers 3.2, thereby adjusting the lateral position of the jack 4. If the rollers 3.2 cannot roll during adjustment, the locking screws 3.3 can be tightened first to move the jack 4 away from the crossbeam 1. Then, the rollers 3.2 can be adjusted to the appropriate position. Finally, the top of the jack 4 abuts against the crossbeam 1 and the locking screws 3.3 are tightened. After adjustment, ensure that the telescopic shaft's extension direction is parallel to the spindle's axis. Preferably, the telescopic shaft and the electric spindle 9 are coaxially arranged.

[0022] In this embodiment, as shown in Figure 1, a pair of lower columns 10 are also provided at the bottom of the worktable 8. The bottom of the lower columns 10 is mounted on a support 11, and a safety bracket 14 is installed on the lower columns 10. The safety bracket 14 supports the lower end of the electric spindle 9. By setting the lower columns 10, a discharge space is provided below the worktable 8, and the ejected spindle falls into this discharge space. To prevent the spindle from falling randomly after being ejected and causing damage, the safety bracket 14 supports the spindle. Further, as shown in Figure 2, the safety bracket 14 includes a connecting frame 14.1 and an arc plate 14.3. The connecting frame 14.1 is installed on the lower columns 10 and is arranged horizontally. A connecting plate 14.2 is provided on the arc plate 14.3, and the connecting plate 14.2 has an opening.

[0023] The connecting plate 14.2 and the connecting bracket 14.1 are connected by locking bolts installed in the waist-shaped hole, and there are at least two locking bolts. By adjusting the locking bolts, the distance between the two arc-shaped plates 14.3 can be adjusted, thereby accommodating electric spindles 9 of different sizes. Of course, in order to accommodate various models of electric spindles 9, the size of the arc-shaped plate 14.3 is also required. Preferably, the arc of the arc-shaped plate 14.3 should be set according to the largest circumferential diameter of the electric spindle 9, so that it can accommodate various models of electric spindles 9. Although for small-diameter electric spindles 9, the electric spindle 9 may be deflected in the safety bracket 14, it will still not fall off and will not be damaged. Of course, in this embodiment, it is preferred that one model of electric spindle 9 corresponds to one safety bracket 14. During maintenance, the corresponding safety bracket 14 can be replaced, and the arc of the arc-shaped plate 14.3 of the safety bracket 14 matches the outer diameter of the corresponding electric spindle 9.

[0024] In this embodiment, as shown in FIG1, a protective pad 15 is installed on the top of the support 11 and the protective pad 15 is located below the electric spindle 9. The protective pad 15 is made of soft material, such as a rubber pad. The protective pad 15 protects the spindle from rigid contact with the support 11, thereby preventing the spindle from being damaged.

[0025] In this embodiment, the manual hydraulic pump 7 is a prior art product and is a commercially available product. The workbench 8 has an installation area where the manual hydraulic pump 7 is installed. The manual hydraulic pump 7 in this embodiment includes a handle 7.1, a pressure gauge 7.2, an unloading valve 7.3, and an oil tank 7.4. The oil supply end of the manual hydraulic pump 7 supplies oil to the jack 4 through a hydraulic hose 5. Since both the manual hydraulic pump 7 and the jack 4 are commercially available products, and supplying oil to the jack 4 through the manual hydraulic pump 7 is also prior art, their specific connection relationships and working principles will not be elaborated upon.

[0026] The working process of this utility model is as follows: When disassembling the imported high-speed electric spindle 9, first remove the other parts, leaving only the electric spindle 9. Only the electric spindle 9 needs to be hoisted and placed vertically into the positioning sleeve 13. During hoisting, the jack 4 can be moved away to provide space for the hoisting of the electric spindle 9. Then, the press-fit transition head 12 is placed on the telescopic shaft, and the jack 4 is moved to keep the spindle, press-fit transition head 12 and jack 4 on the same axis. The manual hydraulic pump 7 works, and under the action of the jack 4, the spindle journal can be moved out of the spindle sleeve at a uniform speed, thereby realizing the disassembly of the electric spindle 9.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
