Description
Technical Field
The utility model relates to a running-in platform especially relates to a running-in platform servo motor flexible coupling device.
Background
The running-in table of the electric power steering column production line is used as an important ring of actual production and plays an important role in running in the worm gear in advance. The worm gear and worm speed reducing mechanism through running-in is more sufficient in lubrication, mechanical parts are more matched, the torque output of the motor is ensured to be more stable, the fluctuation is reduced, and the peak value is reduced.
The existing running-in table is rigidly connected with parts, and a driving motor of a machine tool directly drives a worm through a metal sleeve. In the running-in process, the processes of starting, finishing, forward and reverse switching and the like have impact, so that the running-in failure is caused, and the torque value and the fluctuation become large. And the beat is increased by slowly reducing the rotating speed of the driving motor, and the cost is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned problem of the prior art, the utility model provides a running-in platform servo motor soft connection device both guarantees the running-in beat, has reduced the impact force again, is convenient for change the maintenance simultaneously.
The utility model discloses a running-in platform servo motor flexible connection device, its concrete structure is as follows:
the running-in table comprises a metal sleeve arranged at one end of a running-in table servo motor, and further comprises a first hub, a soft connecting sleeve and a first fixing bolt, wherein one end of the metal sleeve is closed, an external spline is arranged on the axis of the end face of the metal sleeve, a threaded hole is formed in the axis of the external spline, and an internal spline is arranged in the first hub and is matched with the external spline of the metal sleeve; the soft connecting sleeve is provided with two open ends, the inner wall of the soft connecting sleeve is provided with an inner spline which is matched with the first hub and a second hub on the worm gear to be run in, one end of the soft connecting sleeve is matched and sleeved on the first hub and is fixedly connected with a threaded hole of the external spline of the metal sleeve through a first fixing bolt arranged inside the soft connecting sleeve, and the other end of the soft connecting sleeve is matched and sleeved with the second hub.
The soft connecting sleeve is made of wear-resistant nylon rubber material.
Lubricating grease is further arranged between the inner spline of the soft connecting sleeve and the first and second hubs.
Use the utility model discloses a running-in platform servo motor soft connection device has obtained following beneficial effect:
1. the combined design of the soft connecting sleeve and the metal sleeve is adopted, so that the running-in rhythm is guaranteed, the impact force is reduced, meanwhile, the abrasion and the replacement are convenient, the cost is low, and the maintenance is easy.
2. The soft connecting sleeve and the metal sleeve are connected by the hub bolt, so that the soft connecting sleeve and the metal sleeve can synchronously rotate without slipping.
3. And lubricating grease is arranged between the internal spline and the gear hub, so that quick installation in place can be guaranteed.

Detailed Description
The following describes a flexible connection device for a servo motor of a running-in table in accordance with the present invention with reference to the accompanying drawings and embodiments.
As shown in fig. 1-2, the flexible connection device for the servo motor of the running-in table of the present invention comprises a metal sleeve 1 disposed on one end of the servo motor of the running-in table (located on the left side of the metal sleeve 1 in fig. 2, not shown), a first wheel hub 2a, a flexible connection sleeve 3 and a first fixing bolt 4a, wherein one end of the metal sleeve 1 is closed, an external spline 5 is disposed on the axis of the end surface, a threaded hole (not shown) is disposed on the axis of one end of the external spline 5, and an internal spline is disposed in the first wheel hub 2a and is disposed on the external spline 5 of the metal sleeve 1 in a matching manner; the both ends of the soft connecting sleeve 3 are open, the inner wall is provided with an inner spline 7 matched with the first hub 2a and the second hub 2b on the worm gear 6 to be run in, one end of the soft connecting sleeve 3 is matched and sleeved on the first hub 2a and is connected and fixed with a threaded hole of the outer spline 5 of the metal sleeve 1 through the first fixing bolt 4a arranged inside, and the other end of the soft connecting sleeve is directly matched and sleeved with the second hub 2b through the inner spline 7. In fig. 2, a second fixing bolt 4b is fixed to the second hub 2 b.
As an embodiment, the soft connection sleeve 3 is made of wear-resistant nylon rubber material, but other similar materials can be used.
In addition, lubricating grease is also arranged between the internal spline 7 of the flexible connecting sleeve 3 and the first and second hubs 2a and 2b to play a role in lubrication so as to ensure quick installation in place.
When in use, the soft connecting sleeve 3 is firstly arranged on the metal sleeve 1 at one end of the servo motor of the running-in table machine tool, and then the soft connecting sleeve 3 is driven to move and is directly sleeved with the second hub 2b of the worm gear 6; then the motor is driven to rotate, and the worm and gear 6 assembly is driven to run in through the flexible connection device. When the driving motor is started, reversed and finished, due to the existence of the soft connecting sleeve 3, the impact on parts can be effectively reduced, the running-in rhythm cannot be increased, and the method is simple and effective.
However, those skilled in the art should realize that the above embodiments are only used for illustrating the present invention and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the appended claims as long as they are within the true spirit of the present invention.
