Embodiment Construction
[0018] Such as figure 1 , 2 As shown, the present invention is used for the centrifugal fixed fixture of turning, comprises sleeve 1, back-moving spring 2, connecting rod 3 and elastic collet 4, and elastic collet 4 comprises fixed seat and a group is arranged on fixed seat and leaves between For the jaws of the gap, the diameter of one end of the sleeve 1 is larger than the diameter of the other end, the end with a long diameter is the long-diameter end 5, and the end with a short diameter is the short-diameter end 6, and the end of the short-diameter end 6 is axially provided with a through hole; One side of the long-diameter end 5 in the sleeve 1 is provided with a fixed groove 7 that opens toward the short-diameter end 6 and accommodates the return spring 2. The return spring 2 is a compression spring, and one end of the return spring 2 is connected to the bottom of the fixed groove 7. The return spring The other end of 2 is connected with the connecting rod 3, and the co...

The invention discloses a centrifugal fixing clamp used for turning. The centrifugal fixing clamp comprises a sleeve, a resetting spring, a connection rod and an elastic chuck, wherein the sleeve is internally provided with a fixing groove connected with the resetting spring; the other end of the resetting spring is connected with the connection rod; a limiting plate is arranged at the groove opening of the fixing groove; a fixing device for fixing the connection rod is arranged between the resetting spring and the limiting plate; a centrifugal tensioning device comprises centrifugal blocks, a pull rod and a limiting sleeve; the centrifugal blocks are arranged on the two sides of the fixing groove; one end of each pull rod is connected with the corresponding centrifugal block and the other end of each pull rod is connected with the tail part of the limiting sleeve; the elastic chuck sleeves the limiting sleeve and a tapered hole is formed in the inner wall of the head of the limiting sleeve. According to the centrifugal fixing clamp used for turning, the defects that a pull rod is used for clamping a workpiece by an existing turning clamp, the clamp is easy to damage by rotation torque and the clamping and fixing effect is poor are overcome, and the centrifugal fixing clamp used for turning utilizes rotation and centrifuging to clamp the workpiece, avoids damage to the clamp, and has a good clamping and fixing effect.
Description
technical field [0001] The invention belongs to the field of fixing devices for workpieces or cutting tools, and in particular relates to a centrifugal fixing fixture for turning. Background technique [0002] Turning is a method of cutting a workpiece on a lathe by using the rotation of the workpiece relative to the tool. Turning is suitable for machining rotary surfaces. Most workpieces with rotary surfaces can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and rotary forming surfaces. The tools used are mainly turning tools. The cutting energy of turning is mainly provided by the workpiece, not by the tool. Things to pay attention to in the turning process are: reasonable selection of cutting amount, reasonable selection of cutting tools, reasonable selection of fixtures, etc. [0003] For the consideration of reasonable selection of fixtures, fixtures are devices used to fix ...
