[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.
[0023] Please refer to Figures 1-4 The utility model proposes a spindle auxiliary installation mechanism, including a support plate 3, with slide bars 1 at the four corners of the top of the support plate 3, and the top of the slide bar 1 is fixedly connected to a connecting plate 4, and a lifting assembly is provided on the top of one side of the connecting plate 4. The lifting assembly includes a screw rod 2 movably sleeved on the connecting plate 4 and the inside of the support plate 3, and the outer fixed sleeve of the screw rod 2 is provided with a steering worm gear 14, and the screw rod 2 passes through the top of one side of the connecting plate 4 and the movable sleeve is provided with an adjusting box 17. The adjusting box 17 is fixedly connected to the top of the connecting plate 4.
[0024] Please refer to Figure 2 The outer movable sleeve of the slide rod 1 is provided with a lifting frame 6, and the bottom of the lifting frame 6 is fixedly connected to a mounting plate 9. A limiting slot 10 is provided inside the mounting plate 9, and the inner sleeve of the limiting slot 10 is provided with the main shaft body 5. The limiting slot 10 inside the mounting plate 9 facilitates the limiting of the main shaft body 5, thereby facilitating the installation of the main shaft body 5.
[0025] Please refer to Figure 4 An installation cavity 12 is provided inside the adjustment box 17 , and a limit block 11 is fixedly provided outside the installation cavity 12 , and the limit block 11 is movably connected to the installation cavity 12 .
[0026] Please refer to Figure 3 , guide holes 8 are provided at the four corners of the lifting frame 6, and the slide bar 1 is movably sleeved in the guide holes 8. The slide bar 1 moves up and down through the guide holes 8 opened by the lifting frame 6, thereby increasing its stability during movement.
[0027] Please refer to Figure 3The lifting frame 6 has a threaded hole 16 formed inside, and the screw rod 2 is threadedly engaged with the lifting frame 6. The lifting frame 6 moves up and down outside the screw rod 2 through the threaded hole 16, and the lifting frame 6 slowly lifts the spindle body 5. The force and speed during the lifting process are manually adjusted to prevent the spindle body 5 from being damaged by strong assembly. This prevents the spindle body 5 from being damaged during the installation process, while saving time and cost.
[0028] Please refer to Figure 3 The outer movable sleeve of the slide rod 1 is provided with a guide cylinder 7, and the top of the guide cylinder 7 is fixedly connected to the lifting frame 6 to ensure that the guide cylinder 7 at the bottom of the lifting frame 6 can move in the expected direction, thereby increasing the stability of the lifting frame 6 when moving.
[0029] Please refer to Figure 4 The top of the regulating box 17 is threadedly mounted with an inspection cover 18, which is convenient for opening the inspection cover 18 to repair the inside of the regulating box 17.
[0030] Please refer to Figure 3 A plurality of lightweight holes 15 are provided inside the support plate 3 and the connecting plate 4. The lightweight holes 15 on the outside of the support plate 3 and the connecting plate 4 are used to reduce the overall weight while maintaining or improving the strength and performance of the material. The lightweight holes 15 are usually non-stressed areas or areas with less stress, and the lightweight goal is achieved by dispersing stress and reducing material usage.
[0031] Working principle in this embodiment:
[0032] First, the spindle body 5 to be installed is clamped in the limit slot 10. At this time, the hand crank handle 19 is manually rotated clockwise or counterclockwise. The hand crank handle 19 drives the worm 13 to rotate, and then during the rotation process, the worm 13 drives the meshing steering worm gear 14 to rotate, so that the steering worm gear 14 drives the screw rod 2 to rotate. During this process, the lifting frame 6 outside the screw rod 2 drives the spindle body 5 to move up and down. During the installation of the spindle body 5, the spindle body 5 is slowly lifted up by the lifting frame 6, and the force and speed during the lifting process are manually adjusted to avoid damage to the spindle body 5 due to strong assembly and damage to the spindle body 5 during the installation process, while saving time and cost.
[0033] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
