Description
Technical Field
[0001] The utility model relates to a lathe, in particular to a lathe clamp with a self-adapting function. Background Art
[0002] A lathe is a machine tool that primarily uses a turning tool to perform turning operations on rotating workpieces. Lathes are the most important type of metal cutting machine tool and are the most common type of machine tool in general machine manufacturing plants. They are also known as mother machine tools.
[0003] There is an existing lathe fixture device with adaptive function (application number: 202322658675.2) which has the advantage of being able to conveniently adaptively clamp workpieces of various styles. However, the above problem still exists. When using a lathe to process a workpiece, the workpiece needs to be fixed on the fixture on the lathe. Due to different production requirements, it is often necessary to clamp and fix workpieces of different shapes. The above device can achieve adaptive clamping and fixing by setting multiple restrictive elastic members. However, since the workpiece needs to be rotated when using a machine tool to process the workpiece, after the above device fixes the workpiece, there is a deviation between the position of the workpiece and the center position of the fixture. At this time, when the workpiece is rotated, the workpiece cannot be rotated, which easily affects subsequent processing work and is inconvenient for centering the workpiece. Adaptive clamping and fixing work is not convenient. When processing the workpiece, after the fixture is fixed, the right end of the workpiece can be processed. At this time, if the staff needs to process the left end of the workpiece, the workpiece needs to be disassembled and reinstalled, which is inconvenient for switching the workpiece processing end face and inconvenient for the staff to operate.

[0026] Working principle:
[0027] When fixing the workpiece:
[0028] One end of the vertical plate 1 is connected to the lathe rotation drive structure, and the workpiece is placed between the upper and lower rod bodies 2a6. The motor 1 2a3 starts to work, and the motor 1 2a3 drives the double-headed threaded rod 2a1 to rotate. The double-headed threaded rod 2a1 drives the cross block 2a2 to move inward, and then the cross plate 4 moves inward, so that the rod body 2a6 moves inward, and the rod body 2a6 is tightly fitted with the workpiece. More specifically, as Figure 2 As described above, due to the double-threaded structure of the double-threaded rod 2a1, the upper and lower rod bodies 2a6 move toward each other with the same movement amount to press against the workpiece placed between the upper and lower rod bodies 2a6, that is, the clamping space between the upper and lower rod bodies 2a6 is always centered, which solves the problem of deviation between the position of the workpiece and the center position of the fixture; then, as the upper and lower rod bodies 2a6 continue to move and continuously clamp the workpiece, the upper and lower rod bodies 2a6 can adapt to the surface shape of the workpiece for clamping; therefore, the setting of the spring 2a5 allows the rod body 2a6 to be retracted and contracted. At this time, the rod body 2a6 presses against different positions of the workpiece according to the surface shape of the workpiece. After the pressure sensor 2a11 detects an increase in pressure, the electric push rod 2a10 opens When the lathe starts working, the electric push rod 2a10 drives the rod body 2a6 to move to the right, and the rod body 2a6 drives the clamping block 2a7 to move to the right. The clamping block 2a7 cooperates with the plate body 2a8 to clamp the rod body 2a6 into position, thereby achieving clamping and fixing of the workpiece. The lathe rotation drive structure drives the vertical plate 1 to rotate, thereby achieving rotation of the workpiece, thereby facilitating processing of the workpiece. When the other end of the workpiece needs to be processed, the electric push rod 2 11 drives the U-shaped plate 10 to move to the right, and at the same time, the motor 2 6 starts working, and the motor 2 6 drives the gear 1 7 to rotate, and the gear 1 7 drives the gear 2 8 to rotate, and the gear 2 8 drives the housing 9 to rotate, thereby achieving rotation of the workpiece, facilitating switching of the workpiece processing end face, and thereby facilitating processing of the other end of the workpiece.
[0029] Example 2:
[0030] Refer to the attached Figure 1-6 : In this embodiment, a lathe clamp with adaptive function is provided, wherein the clamping structure 2 may further include a rubber block 2b1, one end of the rubber block 2b1 is fixedly connected to one end of the rod body 2a6, and the setting of the rubber block 2b1 may improve the stability of the clamping fixation.
[0031] Working principle:
[0032] When the rod body 2a6 is subjected to force to clamp the workpiece, the rubber block 2b1 is in contact with the workpiece, thereby fixing the workpiece and improving the stability of the workpiece fixation.
