Description

Technical Field

[0001] The present invention relates to the technical field of robot end tooling, and in particular to an end tooling. Background Art

[0002] At present, most of the high-voltage connectors of the central switch cabinet in the substation room are operated manually by operators. To connect or disconnect the high-voltage connector, the power distribution personnel need to go to the site to operate, loosen the upper and lower knobs, and then move the high-voltage connector to one side. The operation is cumbersome and time-consuming. At the same time, there may be risks of insufficient tightening or forgetting a knob, which is inefficient and increases the workload of personnel.

[0003] Therefore, a machine is needed to replace manual labor to solve the problem of cumbersome manual operation and the risk of improper operation of the existing central high-voltage connector, so as to avoid the possibility of improper tightening or forgetting a knob during manual operation.

The terminal tool includes a driving structure, an outer frame, a knob sleeve, and a high-voltage connecting piece sleeve. The driving structure is installed on the outer frame, and the knob sleeve and the high-voltage connecting piece sleeve are installed on the driving structure. The driving structure is used to drive the knob sleeve and the high-voltage connecting piece sleeve to rotate. The knob sleeve is used to rotate the upper knob and the lower knob of the connecting piece. A raised edge is provided at the mouth of the high-voltage connecting piece sleeve. The high-voltage connecting piece sleeve is used to insert the lower knob of the connecting piece. The raised edge drives the high-voltage connecting piece body to rotate, so as to connect or disconnect the high-voltage connecting piece body.

[0007] Furthermore, the driving structure includes a servo motor, a reducer and a synchronous belt transmission mechanism, the servo motor and the reducer are both installed in the outer frame, the reducer is connected to the servo motor, and the servo motor is also connected to the synchronous belt transmission mechanism, and is used to drive the synchronous belt transmission mechanism to operate through the servo motor, and the two ends of the synchronous belt transmission mechanism are respectively connected to the knob sleeve and the high-voltage connecting plate sleeve to drive the knob sleeve and the high-voltage connecting plate sleeve to rotate according to the transmission of the synchronous belt transmission mechanism.

[0008] Furthermore, the synchronous belt transmission mechanism includes a sealing cover, a synchronous belt, a first synchronous pulley, a second synchronous pulley, an intermediate shaft, and a bearing. The sealing cover is connected to the intermediate shaft. The first synchronous pulley and the second synchronous pulley are respectively located at two ends of the synchronous belt. The first synchronous pulley is respectively connected to the servo motor and the knob sleeve. The second synchronous pulley is installed on the intermediate shaft and is used to drive the rotation of the second synchronous pulley through the rotation of the first synchronous pulley. The second synchronous pulley is also connected to the high-voltage connecting plate sleeve. The intermediate shaft is fixed on the bearing, and the bearing is installed on the outside of the outer frame.

[0009] Furthermore, it also includes two couplings, one coupling is used to connect the first synchronous belt pulley and the knob sleeve, and the other coupling is used to connect the second synchronous belt pulley and the high-voltage connecting plate sleeve.

[0010] Furthermore, the synchronous belt transmission mechanism also includes a bearing seat, and the bearing seat is respectively connected to the bearing and the outer side of the outer frame.

[0011] Furthermore, it also includes a camera, which is installed on the outside of the outer frame and is used to provide a field of view and positioning for the movement of the knob sleeve and the high-voltage connecting piece sleeve.

[0012] Furthermore, it also includes a camera bracket, and the camera is installed on the outside of the outer frame through the camera bracket.

[0013] Furthermore, the inner diameter of the high-voltage connecting piece sleeve is greater than the inner diameter of the knob sleeve.

[0014] Furthermore, a thread matching with the upper knob and the lower knob of the connecting plate is provided inside the knob sleeve.

[0015] Furthermore, the raised edges are in the shape of long columns, and are provided in plurality, and the plurality of raised edges are used to clamp the bottom of the high-voltage connecting piece body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention accurately controls the operation of the synchronous belt transmission mechanism through the cooperation between the servo motor and the reducer, so that the knob sleeve and the high-voltage connecting plate sleeve at both ends of the synchronous belt transmission mechanism rotate. The knob sleeve realizes automatic loosening and tightening of the knob by rotating the upper knob and the lower knob of the connecting plate. The rotation of the high-voltage connecting plate sleeve causes the raised edge to drive the high-voltage connecting plate body to rotate, thereby realizing automatic shifting of the high-voltage connecting plate body.

[0018] (2) The first synchronous pulley and the second synchronous pulley of the synchronous belt transmission mechanism of the present invention are respectively located at the two ends of the synchronous belt. The rotation of the first synchronous pulley drives the rotation of the second synchronous pulley to ensure the consistency of movement between the two, thereby ensuring that the knob sleeve and the high-voltage connecting plate sleeve respectively connected to the first synchronous pulley and the second synchronous pulley are both rotated, avoiding the risk of improper operation.

[0019] (3) The end tool of the present invention is loaded at the end of the robot arm and can be remotely controlled at any time through a terminal computer, realizing the function of replacing the distribution personnel to operate on site, which has the characteristics of saving manpower and shortening working time, thereby greatly improving work efficiency.

[0020] (4) The end tool of the present invention has the characteristics of simple structure, convenient operation, high efficiency and speed, and does not require professional personnel. It solves the problem of cumbersome manual operation and the risk of improper operation of the existing centrally mounted high-voltage connecting piece, and also avoids the possibility of improper tightening or forgetting a knob during manual operation, thereby improving safety performance.
