Description
Technical Field
The utility model relates to a machine tool chuck, concretely relates to movable jaw annex device of machine tool chuck.
Background
The machine tool chuck consists of a chuck body, movable clamping jaws and a clamping jaw driving mechanism, and is a machine tool accessory which utilizes the movable clamping jaws uniformly distributed on the chuck body to be driven by the clamping jaw driving mechanism to move radially so as to clamp and position a workpiece. The jaw driving mechanism comprises a small bevel gear shaft, a large bevel gear disc and a guide jaw body, the movable jaw is in a step-shaped cuboid block shape, two fixing holes are machined in the movable jaw, and the movable jaw is fixedly installed on the guide jaw body through two screws. As shown in fig. 5, the most common roller component is one in which bearing mounting holes are formed at the left and right ends, a central hole is formed in the middle of the roller component for communication, and the bearing mounting holes at the two ends have higher concentricity requirements. When the existing universal machine tool chuck is used for clamping and machining the roller part, the movable clamping jaws clamp the height of the step, the roller part needs to be positioned and clamped twice, and the bearing mounting hole is machined by using the boring cutter.
Disclosure of Invention
An object of the utility model is to solve the not enough of prior art existence, provide a lathe chuck's activity jack catch annex device, simple structure is novel, and easy dismounting is swift, can increase the tight step height of movable jack catch clamp, can realize the clamping processing to gyro wheel part, and machining efficiency is high, and the concentricity is high.
The utility model adopts the technical proposal that: a movable jaw accessory device of a machine tool chuck comprises a clamping column 1 and fastening screws 2, wherein the clamping column 1 is in a cuboid column shape, a positioning boss 11 is arranged on the lower end face of the clamping column, positioning side plates 12 are arranged on two sides of the lower end of the clamping column, an L-shaped clamping notch 13 is arranged at the upper end of the clamping column, a positioning surface 14 and a clamping surface 15 are formed, the clamping surface 15 is an arc surface, anti-skid grains are arranged on the clamping surface 15, a step connecting hole 16 is arranged in the center of the clamping column 1, the fastening screws 2 are arranged in the step connecting holes 16, the positioning boss 11 is inserted into a fixing hole of a movable jaw, the positioning side plates 12 are in close contact with two side faces of the movable jaw, and the fastening screws.
Compared with the prior art, the utility model following beneficial effect has: simple structure is novel, and easy dismounting is swift, can increase the tight step height of movable jack catch clamp, can realize the clamping processing of gyro wheel part once, and machining efficiency is high, and the concentricity is high.
