In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] As Figures 1-5 Indicated, the utility model maintenance dismounts workbench, is applied to the maintenance dismount of grease type speed reducer, including workbench body 100, still including:

[0027] Clamping mechanism, including rotatingly arranged first support ring plate 1 on the workbench body 100 and second support ring plate 2 arranged on the upside of the first support ring plate 1 and oppositely distributed with the first support ring plate 1, the first support ring plate 1 and the second support ring plate 2 are provided with clamping assembly 3 for centering and fixing multiple size grease type speed reducer between them;

[0028] Turnover mechanism 4, including support groove 41 arranged on the outside of the lower side of the workbench body 100, rotating assembly 42 arranged on the inner wall of the support groove 41 and used for overturning the workbench body 100 around x-axis, overturning the workbench body 100, for making grease type speed reducer to carry out multi-angle dismounting operation.

[0029] In specific implementation, the first rotating support ring plate 1 and the second support ring plate 2 are arranged on the workbench body 100, and the clamping assembly 3 is arranged between the first rotating support ring plate 1 and the second support ring plate 2, so that the grease type speed reducer of different models and sizes can be applied, and the grease type speed reducer can be quickly fixed, so that the grease type speed reducer is stably fixed on the workbench body 100, and the oil seal can be conveniently disassembled, maintained and repaired.

[0030] The support groove 41 is stably placed on the work surface and is rotatably connected to the rotating assembly 42 at the lower side of the workbench body 100. Under the action of the rotating assembly 42, the workbench body 100 and the grease type speed reducer fixed on the workbench body 100 are flipped around the x-axis, so that the fixed grease type speed reducer can be maintained and disassembled at multiple angles, thereby improving the application range.

[0031] In an embodiment, the clamping assembly 3 comprises an outer tooth ring 31 coaxially arranged with the first support ring plate 1 and the second support ring plate 2, two or more T-shaped clamping blocks 32 uniformly sliding on the outer tooth ring 31 and moving radially along the outer tooth ring 31, and a transmission unit 33 arranged on the outer tooth ring 31 and used for synchronously driving the two or more T-shaped clamping blocks 32 to move. In this way, the outer tooth ring 31 is coaxially arranged between the first support ring plate 1 and the second support ring plate 2, and the two or more T-shaped clamping blocks 32 are linearly sliding on the outer tooth ring 31 along the radial direction thereof. When one T-shaped clamping block 32 moves radially, the remaining T-shaped clamping blocks 32 are synchronously driven to move radially to the center by the transmission unit 33, so that the synchronous centering and clamping function is realized. The T-shaped clamping block 32 is adjustable, and is suitable for different models and sizes of speed reducers, so that the grease type speed reducer can be quickly fixed.

[0032] It should be noted that the inner arc surface of the T-shaped clamping block 32 is bonded with a rubber pad, which is flexibly contacted with the shell of the grease type speed reducer for lossless protection.

[0033] It should be noted that the number of T-shaped clamping blocks 32 is generally three, and the T-shaped clamping blocks 32 are circularly arranged on the outer tooth ring 31.

[0034] In an embodiment, the transmission unit 33 comprises a first gear 331 engaged outside the outer tooth ring 31, a second gear 332 coaxially arranged on the lower side of the first gear 331, and a rack 333 arranged on the non-clamping end side of the T-shaped clamp block 32. In this way, by engaging the first gear 331 outside the outer tooth ring 31, and coaxially arranging the second gear 332 on the lower side of the first gear 331, and the second gear 332 is engaged with the rack 333 assembled with the side of the T-shaped clamp block 32, when rotating the central shaft of the end surface of the first gear 331 and the second gear 332, the engagement of the second gear 332 with the rack 333 will drive the T-shaped clamp block 32 to move linearly along the radial direction, and at the same time, under the meshing action of the first gear 331 and the outer tooth ring 31, the first gear 331 engaged on the other side of the outer tooth ring 31 is driven to rotate, thereby enabling the T-shaped clamp block 32 installed on the other side to move linearly along the radial direction, achieving synchronous centering and clamping function, which is simple and convenient to operate.

[0035] It should be noted that the first gear 331 and the second gear 332 are fixed on the upper end of the central shaft, which extends through the second support ring plate 2 and is installed on the rotating handle.

[0036] In an embodiment, the rotating assembly 42 comprises two sleeves 421 symmetrically arranged on the inner wall of the support groove 41, and a rotating column 422 rotatably arranged in the sleeve 421 and fixed on the outer wall of the workbench body 100 at a corresponding position. In this way, by symmetrically welding two sleeves 421 in the support groove 41, and welding a rotating column 422 on the outer wall of the workbench body 100 at a corresponding position, when the rotating column 422 rotates in the sleeve 421, the grease type speed reducer fixed on the workbench body 100 can be maintained and disassembled at multiple angles, improving the scope of application.

[0037] In an embodiment, a first magnetic member 5 is movably arranged on one side of the rotating column 422, and a metal concave surface 6 is arranged on the peripheral surface of the first support ring plate 1.

[0038] The first magnetic member 5 is used to move along the axial direction of the rotating column 422, so that the magnetic surface of the first magnetic member 5 extends into the metal concave surface 6 and is magnetically attracted and fixed to the metal concave surface 6. In this way, by movably and rotatably arranging the first magnetic member 5 on the outer wall of the rotating column 422, and opening a circle of metal concave surfaces 6 on the peripheral surface of the first support ring plate 1, when the clamping mechanism rotates on the end surface of the workbench body 100 for angle adjustment, the first magnetic member 5 can be moved so that the magnetic plate on the first magnetic member 5 extends into the metal concave surface 6 for magnetic attraction and fixation, achieving angle limitation of circular rotation.

[0039] In an embodiment, the outer wall of the workbench body 100 is provided with a second magnetic member 7.

[0040] The second magnetic member 7 is magnetically attracted and fixed to the metal arc surface (not shown in the figure) arranged on the inner bottom of the supporting groove 41 during the overturning of the workbench body 100. In this way, by embedding the second magnetic member 7 on the outer wall of the workbench body 100, the second magnetic member 7 installed at the corresponding position can be magnetically attracted and fixed to the metal arc surface integrally formed on the inner bottom of the supporting groove 41 when the grease-type speed reducer is fixed on the overturned workbench body 100, so that the overturning angle is limited, and the multi-angle operation is suitable.

[0041] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
