Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of workbenches, in particular to a reversible gear box installation workbench. Background Art
[0002] In the past, large planetary reduction gearboxes were usually installed directly on the ground in the workplace. When the gearbox needed to be flipped, a crane and lifting equipment were used to lift the lugs installed on the threaded holes on the gearbox flange surface for a violent flip. This method not only caused impact damage to the precision components inside the assembled gearbox, reducing the accuracy, but also caused collisions and bumps on the exterior, seriously affecting product performance and appearance.
[0003] To this end, we designed and developed a reversible gearbox installation workbench. Utility Model Content
[0004] (1) Technical problems solved
[0005] In response to the shortcomings of the existing technology, the utility model provides a reversible gearbox installation workbench, which can install two gearboxes at the same time, and can adjust the horizontal height as the height of the installation structure increases. The gearbox can also be flipped at any angle according to assembly needs. It solves the problem that the precision parts inside the assembled gearbox are damaged by impact and the accuracy is reduced, and the appearance is affected by collisions and bumps, which seriously affects the performance of the product.
[0006] (2) Technical solution
[0007] In order to achieve the above-mentioned purpose of being able to install two gearboxes at the same time, and being able to adjust the horizontal height as the height of the installation structure increases, and also being able to flip the gearbox at any angle according to assembly needs, the utility model provides the following technical solution: a flippable gearbox installation workbench, including a base and a gantry installed above the base, and also including:
[0008] A turning mechanism for turning the gearbox on the gantry. The turning mechanism is located below the gantry and includes a workbench movably mounted on the gantry. Positioning planes are fixedly mounted on both sides of the workbench. A cycloid motor is fixedly mounted on one side of the positioning plane. A worm gear pair is fixedly mounted below the cycloid motor.
[0009] A reciprocating mechanism is used to adjust the gear box on the gantry to the upper and lower horizontal planes for further assembly. The reciprocating mechanism includes a workbench opened in the gantry slide rail, and mounting seats are fixedly installed on both sides of the lower middle position of the gantry. Hydraulic cylinders are fixedly installed on the two mounting seats. The two hydraulic cylinders are fixedly connected through a crossbeam. The two sides of the crossbeam are movably installed on the gantry through the slide rail seats. Sprockets are fixedly installed on both sides of the crossbeam, and fixed blocks are fixedly installed on the bottom of both sides of the gantry. Tension chains are fixedly installed on the two fixed blocks, and the tension chain is fixedly mounted on the workbench through the sprockets on the crossbeam.
[0010] Preferably, an electric control cabinet is fixedly mounted on one side of the gantry.
[0011] Preferably, a limiter is fixedly installed on the gantry, and the number of the limiters is two.
[0012] (3) Beneficial effects
[0013] Compared with the prior art, the present invention provides a reversible gearbox mounting workbench, which has the following beneficial effects:
[0014] 1. The reversible gearbox installation workbench is manually controlled by the switch button corresponding to the motor rotation on the electric control cabinet. The cycloid motor starts to rotate and drives the worm gear to operate. Since the gearbox installation positioning surface mechanism is connected to the worm gear, the gearbox as a whole is driven to perform a reversal action. When the required assembly angle is reached, the switch button corresponding to the hydraulic motor rotation on the electric control cabinet is manually turned off to stop the work. Due to the self-locking function of the worm gear pair, the entire assembly can be controlled to work stationary at any rotation angle.
[0015] 2. The reversible gearbox is installed on the workbench. By manually controlling the switch button of the corresponding hydraulic cylinder on the electric control cabinet, the hydraulic cylinder starts linear motion to push the beam up and down, and the tension chain on the beam sprocket drives the workbench assembly to move up and down.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Example 1
[0022] See also Figure 1-2 A reversible gearbox mounting workbench includes a base 1 and a gantry 2 mounted above the base 1, and further includes: a reversing mechanism for reversing the gearbox on the gantry 2, the reversing mechanism being located below the gantry 2, and the reversing mechanism including a workbench 4 movably mounted on the gantry 2, positioning planes 8 being fixedly mounted on both sides of the workbench 4, a cycloid motor 9 being fixedly mounted on one side of the positioning plane 8, and a worm gear pair 10 being fixedly mounted below the cycloid motor 9,
[0023] The present invention is further described in detail, an electric control cabinet 3 is fixedly installed on one side of the gantry 2.
[0024] During the installation process, if the installed semi-finished gearbox needs to be flipped for further assembly and inspection, the cycloid motor 9 starts to rotate and drives the worm gear by manually controlling the switch button of the corresponding motor rotation on the electric control cabinet 3. Since the gearbox installation positioning plane 8 is connected to the worm gear, the gearbox as a whole is driven to flip. When the angle required for assembly is reached, the switch button of the corresponding motor rotation on the electric control cabinet 3 is manually turned off to stop. Due to the self-locking function of the worm gear pair 10, the entire assembly can be controlled to work stationary at any rotation angle.
[0025] As can be seen from the above, the self-locking function of the worm gear pair 10 is a prior art, and its working principle will not be described in detail;
[0026] Example 2
[0027] like Figure 1-2As shown, on the basis of the above-mentioned embodiment 1, a reciprocating mechanism is added for adjusting the gear box on the gantry 2 to the upper and lower horizontal planes for further assembly. The reciprocating mechanism includes a workbench 4 provided in the slide rail 13 of the gantry 2, and mounting seats 15 are fixedly installed on both sides of the lower middle position of the gantry 2. Hydraulic cylinders 7 are fixedly installed on the two mounting seats 15. The two hydraulic cylinders 7 are fixedly connected through a crossbeam 5. Both sides of the crossbeam 5 are movably installed on the gantry 2 through the slide rail seats 6. Sprockets 16 are fixedly installed on both sides of the crossbeam 5. Fixed blocks 14 are fixedly installed on the bottom of both sides of the gantry 2. Tension chains 11 are fixedly installed on the two fixed blocks 14. The tension chain 11 is fixedly installed on the workbench 4 through the sprockets 16 on the crossbeam 5.
[0028] The present invention is further specifically described in detail. A limiter 12 is fixedly installed on the gantry 2. There are two limiters 12, which enable the workbench 4 and the beam 5 to move within a safe range.
[0029] When the installation process requires that the installed semi-finished gearbox needs to be adjusted up and down horizontally for further assembly and inspection, the switch button of the corresponding control hydraulic cylinder 7 on the manual control electric control cabinet 3 is pressed, and the hydraulic cylinder 7 starts linear action to push the crossbeam 5 upward. One end of the tension chain belt in the structure is fixed on the gantry 2, and the other end is fixed on the workbench 4 bracket. When the crossbeam 5 moves upward, the tension chain 11 drives the workbench 4 upward through the sprocket 16. When it moves to the required height, the button for controlling the operation of the hydraulic cylinder 7 can be manually turned off; when the assembly is completed, the switch button of the corresponding control hydraulic cylinder 7 on the manual control electric control cabinet 3 is pressed, and the hydraulic cylinder 7 starts to retract and drive the crossbeam 5 to move downward. The tension chain 11 drives the workbench 4 to move downward through the sprocket 16. When it moves to the required height, the button for controlling the operation of the hydraulic cylinder 7 can be manually turned off, and the gearbox can be removed.
[0030] Compared with the traditional assembly mode, the utility model has a more convenient installation platform for assembled products. It can not only flip the installed gearbox at any angle without damage, but also can be controlled at the most convenient installation operation plane through height adjustment, reducing the labor intensity of operators. At the same time, the equipment can install two gearboxes simultaneously, greatly improving production efficiency.
