Description

Technical Field

[0001] The utility model relates to the technical field of lathe equipment, in particular to a novel back-shaft chuck for a lathe. Background Art

[0002] The back spindle chuck is mainly used to clamp materials and tools. It is a commonly used tool in machining centers such as machine tools. It is mainly used in conjunction with the spindle or motor drive shaft of the machine tool.

[0003] However, the back-axle chuck in the prior art has the disadvantage that it is difficult to improve the accuracy of the workpiece position during processing. When in use, the workpiece is not clamped and is prone to shifting, resulting in reduced processing accuracy, which is not conducive to use. Moreover, the back-axle chuck in the prior art has the disadvantage that it is difficult to improve the applicability efficiency of the device. When in use, the device can only clamp one type of workpiece. When clamping different types of workpieces, the contact area with the workpiece surface will be reduced, which makes the clamping unstable and causes the workpiece to loosen and fall off easily, thereby reducing the processing efficiency. Utility Model Content

[0004] The utility model aims to provide a novel back-spindle chuck for a lathe to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The inner side wall of the clamping sleeve is clamped with an adapter component, and the adapter component includes a clamping slot, a clamping block and an adapter ring. The inner side wall of the clamping sleeve is provided with a clamping slot, and the inside of the clamping slot is clamped with a clamping block, and one side of the clamping block is fixedly connected with an adapter ring.

[0009] Preferably, a threaded ring is fixedly connected to the outer surface of the clamping shaft seat, and an adjusting knob is threadedly connected to the outer surface of the threaded ring.

[0010] Preferably, a connecting slot is provided on one side of the limiting plate, and a protective pad is fixedly connected inside the connecting slot.

[0011] Preferably, an inner side wall of the adjusting knob is provided with a mounting slot, and the interior of the mounting slot is fixedly connected with an inner wall thread.

[0012] Preferably, the inner thread of the limit slider is connected to the outer surface of the limit screw, and the two sides of the limit slider are clamped to the inner side wall of the fixing frame.

[0013] Preferably, one end of the telescopic rod is fixedly connected to one side of the limit sliding block, and the other end of the telescopic rod is fixedly connected to the limit plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. This new type of back-axle chuck for a lathe is provided with a fixed frame, a limit screw, a turning knob, a limit slider, a telescopic rod, a spring and a limit plate. When in use, an operator can turn the turning knob to drive the limit screw to rotate, and the rotation of the limit screw drives the limit slider to move up and down, thereby driving the position of the telescopic rod to be adjusted up and down. When processing the workpiece, the operator adjusts the limit device to the required position. At this time, the limit plate limits the surface of the workpiece to prevent the workpiece position from shifting, thereby achieving the effect of improving the accuracy of the workpiece position during processing, and avoiding the situation in which the workpiece cannot be clamped and is easily shifted during processing, thereby reducing the processing accuracy and being unfavorable for use.

[0016] 2. This new type of back-axle chuck for a lathe has a slot, a block and an adapter ring. When in use, the slot and the block have the same area. After the block is inserted into the slot, the adapter ring can be replaced as needed to fit the surface of the special-shaped workpiece, increase the fitting area, and improve the clamping stability, thereby achieving the effect of improving the applicability of the device and avoiding the situation where the device can only clamp one type of workpiece. When clamping different types of workpieces, the fitting area with the workpiece surface will be reduced, which will easily lead to unstable clamping, and then cause the workpiece to loosen and fall off easily, thereby reducing the processing efficiency.
