Abstract
The utility model discloses a ram focus compensation arrangement, it is vice including motor, lead screw, balancing weight and linear guide, the motor is installed on the ram tailstock, and the lead screw erects on the ram tailstock, this lead screw pass behind the balancing weight with the output shaft of motor, the both sides of balancing weight all are connected with linear guide vice, the vice both ends fixed support of linear guide on the ram tailstock. When the movement stroke of the ram is longer, the displacement of the whole gravity center of the ram is relatively smaller.
Description
Technical Field
The utility model belongs to the lathe field especially relates to a ram focus compensation arrangement.
Background
For the numerical control floor type milling and boring machine, when the ram moves forwards and backwards, the whole gravity center of the ram naturally moves along with the ram. When the gravity center compensation device is not arranged, the overall gravity center displacement of the ram is consistent with the operation of the ram, and when the ram wants to obtain a longer stroke, in order to prevent the gravity center of the ram from moving out of the front supporting point and the rear supporting point, the distance of the front supporting point and the rear supporting point needs to be increased, namely the ram body is enlarged.
Disclosure of Invention
In order to overcome the difficult problem of above-mentioned prior art, the utility model provides a ram focus compensation arrangement makes ram motion stroke longer, and the whole focus displacement of ram is less relatively.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a ram focus compensation arrangement, includes motor, lead screw, balancing weight and linear guide are vice, the motor is installed on the ram tailstock, and the lead screw erects on the ram tailstock, this lead screw pass behind the balancing weight with the output shaft of motor, the both sides of balancing weight all are connected with linear guide vice, the vice both ends fixed support of linear guide on the ram tailstock.
In the above technical solution, the motor is a servo motor.
In the above technical scheme, the lead screw is a ball screw.
In the technical scheme, the motor is connected with the lead screw through the coupler.
The utility model has the advantages that: the ram gravity compensation device is compact and simple in structure, when the ram moves forwards and backwards, the servo motor is automatically controlled by the numerical control system to drive the balancing weight to move reversely, the change of the whole gravity center position of the ram is smaller than the running distance of the ram, when the moving stroke of the ram is larger than the distance between the front supporting point and the rear supporting point of the ram, the gravity center of the ram cannot move out of the front supporting point and the rear supporting point, and the purpose of ram gravity compensation is achieved.
Drawings
Fig. 1 is a schematic sectional view of the present invention.
FIG. 2 is a schematic view of the structure A-A in FIG. 1.
Wherein: 1. the device comprises a motor, a screw rod 2, a balancing weight 3, a linear guide rail pair 4, a ram 5 and a ram tailstock 6.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the ram gravity center compensation device comprises a motor 1, a lead screw 2, a balancing weight 3 and a linear guide rail pair 4, wherein the motor 1 is installed on a ram tail frame 6, the lead screw 2 is erected on the ram tail frame 6, the lead screw 2 penetrates through the balancing weight 3 and then is connected with an output shaft of the motor 1, two sides of the balancing weight 3 are connected with the linear guide rail pair 4, and two ends of the linear guide rail pair 4 are fixedly supported on the ram tail frame 6. The ram 5 is fixedly connected with the ram tailstock 6 and can move horizontally.
The weight of the balancing weight 3 and the stroke of the compensating device can be correspondingly adjusted according to the actual weight, the shape, the stroke and the position of the supporting point of the ram 5, and the fact that the whole gravity center of the ram does not move out of the position of the supporting point in the whole design stroke is guaranteed.
In the above technical solution, the motor 1 is a servo motor.
In the above technical solution, the screw 2 is a ball screw.
In the technical scheme, the motor 1 is connected with the lead screw 2 through a coupler.
The motor 1 drives the screw rod 2 to rotate, so that the balancing weight 3 moves back and forth along the linear guide rail pair 4. The numerical control system controls the motor 1 to drive the balancing weight 3 to move reversely for a corresponding distance according to the movement direction and the displacement of the ram 5 in real time, so that the whole center of the ram 5 moves reversely for a distance relative to the displacement of the ram 5, the change of the whole gravity center position of the ram is smaller than the running distance of the ram, when the moving stroke of the ram is larger than the distance of the front supporting point and the rear supporting point of the ram, the gravity center of the ram cannot move out of the front supporting point and the rear supporting point, and the purpose of compensating the gravity center of the ram is achieved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
