Problems solved by technology

Most lathe fixtures are installed on the main shaft, and a few are installed on the saddle or bed. Lathe fixtures are divided into different types according to the workpiece positioning methods: centering type, collet type, chuck type, angle iron type and faceplate type. With continuous development, the structure of lathe fixtures has been improved accordingly, and has a good development prospect, but the existing lathe fixtures still have certain deficiencies, and it is believed that they will be further improved in the future to meet the different needs of use; The existing lathe fixtures have certain disadvantages in use. They cannot weaken the vibration generated during the operation of the lathe. Due to resonance, the fixture is easily damaged, the strength of the transmission rod is not good, and the service life is short. The friction between the large lower clamping block and the workpiece makes the clamping of the workpiece unstable, which has a certain impact in the actual use process. Therefore, we propose a lathe fixture that is easy to clamp

Abstract

The invention discloses a lathe clamp facilitating clamping. The lathe clamp comprises a clamp main body and a transmission rod, a lower pressing plate and an upper pressing plate are arranged on theinner side of the clamp main body correspondingly, an upper clamping block is fixedly arranged on the outer surface of the bottom end of the upper pressing plate, and a lower clamping block is fixedlyarranged on the outer surface of the upper end of the lower pressing plate; and an adjusting bolt is arranged on the outer surface of one side of the clamp main body, the adjusting bolt is provided with an adjusting inserting hole, one side of the adjusting bolt is fixedly provided with a damping ring, and a mounting rod is fixedly arranged on the outer surface of one side of the adjusting bolt.According to the lathe clamp facilitating clamping, the damping ring, a reinforcing rib and friction convex blocks are arranged so that vibration generated in the operation process of a lathe can be weakened, damage to the clamp due to resonance is avoided, the overall strength of the transmission rod is increased, the service life of the transmission rod is prolonged, the friction between the lower clamping block and a workpiece can be increased, then clamping of the workpiece is firmer, and a better application prospect is brought.
