Problems solved by technology

[0005] The clamping operation of the TV frame takes a long time, but the processing time of the processing machine for the TV frame is very short
In the total time of machining a TV frame, the ratio of the time occupied by the clamping operation to the time occupied by the processing operation is 2 to 5:1, and the clamping operation of the TV frame consumes a lot of time
Especially when processing TV frames in large quantities, the staff need to perform frequent clamping operations, the labor intensity of the staff is high and waste manpower, the processing efficiency is extremely low, and the production cost of the enterprise is increased, so it is necessary to improve

Embodiment 2

[0042] Example 2, see Figure 5 As shown, the main structure, principle and effect of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The difference is that the power unit 23 is a motor, and the transmission mechanism 22 is a synchronous belt transmission mechanism 22. The synchronous belt transmission mechanism 22 includes a synchronous belt 224 and a synchronous wheel 223 , each synchronous wheel 223 is respectively fixed on the second end of each multi-station clamping column 3 , and the motor is connected to each synchronous wheel 223 through the synchronous belt 224 . The rotating motor and the synchronous wheel 223 transmission mechanism 22 drive the multi-station clamping column 3 to perform forward and reverse rotation, so that the multi-station clamping column 3 performs forward and reverse rotation with the rotation of the rotating motor, thereby switching the workpiece to be processed.

Embodiment 3

[0043] Example 3, see figure 1 , Figure 6 As shown, the main structure, principle and function of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The difference is that each multi-station clamping column 3 adopts a circular shaft body.

Embodiment 4

[0044] Example 4, see Figure 7 , Figure 8 As shown, the main structure, principle and function of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The difference is that each multi-station clamping column 3 is a quadrilateral column.

Abstract

The invention discloses a special clamp for machining a television frame. The special clamp comprises a positioning locking seat and a driving seat. At least one multi-station clamping column is rotationally mounted between the positioning locking seat and the driving seat. The driving seat comprises a first driving device which is in transmission connection with all the multi-station clamping columns. At least one clamping surface is arranged on the column body surface of the middle section of each multi-station clamping column. Second driving devices and a fixing plate are fixed to the positioning locking seat. Positioning locking pins are slidably mounted on the fixing plate. The second driving devices are connected with the first ends of the positioning locking pins. The fixing plate is provided with guide holes with the sizes corresponding to those of the positioning locking pins. The middles of the positioning locking pins are slidably arranged in the guide holes in a penetrating mode. The end face of the first end of each multi-station clamping column is provided with a positioning locking hole. The second ends of the positioning locking pins are matched with the positioning locking holes in an inserting mode correspondingly. The special clamp for machining the television frame is simple in structure, the workpiece changing speed is high, the labor intensity of workers is relieved, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of a TV frame fixture, in particular to a special fixture for processing a TV frame. Background technique [0002] When the TV frame is being processed, the TV frame needs to be fixed on a fixture, the fixture is installed on the machine tool, and the TV frame is processed by the machine tool. [0003] The existing fixture can only fix one workpiece at a time. After the workpiece is processed, the workpiece must be disassembled from the fixture, and the unprocessed workpiece must be fixed on the fixture to continue processing. [0004] At present, the processing enterprises of TV frames all use two-and-a-half-axis or three-axis processing machines for processing, and the TV frame needs to process at least 2 to 3 surfaces, which are processed by milling or drilling. After the clamp is fixed on the fixture, the processing machine can only process one side of the TV frame, and the other side needs to be reinst...
