Clamp for automatically retreating and milling

Abstract

The invention discloses a clamp for automatically retreating and milling. The clamp comprises a clamp body, wherein the upper end of the clamp body is in the shape of a cone which is gradually reduced from outside to inside, a clamping jaw capable of stretching in and out of the clamp body is arranged in the clamp body, a pull rod is further arranged in the clamp body, one end of the pull rod is connected with the clamping jaw, and the other end of the pull rod stretches out of the clamp body, a locating ring is arranged in the clamping jaw and fixedly connected with the clamp body via a fastener, and a locating column is arranged at the centre of the locating ring; a pushing ring is movably arranged at the port of the clamping jaw; an elastic component is arranged between the pushing ring and the locating ring; the pushing ring is sleeved on the locating column; and a placing groove is formed on the top of the pushing ring. The clamp for automatically retreating and milling disclosed by the invention overcomes the shortage that after the machining of the conventional milling clamps is finished, workpieces can be taken out after being cooled, increases machining efficiency, and is suitable for batch machining.

Description

technical field [0001] The invention relates to a milling fixture, in particular to a milling fixture capable of automatically returning materials after processing, and belongs to the technical field of workpiece clamping devices for mechanical processing. Background technique [0002] When milling the end faces of small and medium bearing rings, the attached figure 1 The shown milling fixture includes a clamp body 1, the upper end of the clamp body 1 is tapered from the outside to the inside, and the clamp body 1 is provided with a claw 2 that can extend into and out of the clamp body. There is also a pull rod 3 in the clamp body, one end of the pull rod 3 is connected with the claw 2, and the other end extends out of the clamp body 1, and a positioning ring 4 is arranged inside the clamp claw 2, and the positioning ring 4 is passed through a fastener 5 is fixedly connected with the clamp body. Its working principle is as follows: place the bearing ring to be processed on...

Problems solved by technology

However, the bearing ring will be hot after milling. If it is taken out directly, it may cause the operator's hand to be scalded, and it needs to wait for a period of time, which reduces the processing efficiency and is not suitable for batch processing.
