6 results about "Bar stock" patented technology

A spindle liner for a turning machine has an elongated polymeric member sized to fit within the inner diameter of a spindle and further has a bore through the polymeric member sized and shaped to receive a given size bar stock. The spindle liner may be installed within a spindle and bolted to a spindle flange by an adapter fixed to the spindle liner so that the spindle liner rotates with the spindle. The spindle liner attenuates noise and vibration of the rotating bar stock and eliminates whipping of the free end of the bar stock.

The invention discloses a bar fixing mechanism which comprises a fixing part, a moving part, and a power module. The fixing part comprises a fixing body and first guide protrusions; the first guide protrusions are arranged on the two sides of the fixing body; a mounting groove is formed in the top of the fixing body; a to-be-machined workpiece is arranged in the mounting groove; bending grooves are formed in the two sides of the moving part; the positions of the bending grooves are matched with the positions of the first guide protrusions; the moving part is arranged on the side face, provided with the mounting groove, of the fixed body; the moving part is slidably connected with the fixed body; the first guide protrusions are arranged in the bending grooves; the power module is arranged at the end, away from the mounting groove, of the fixing body; the power module is rotationally connected with the end, away from the mounting groove, of the moving part; the power module drives the moving part to move along a bent groove; and the moving part tightly presses the to-be-machined workpiece arranged in the mounting groove. According to the technical scheme, components of the bar fixing mechanism can be simplified, and movement of the bar mechanism is simplified.

The invention discloses a feeder for heating a bar stock of a mini-tiller and aims to solve the problem of non-uniform heating caused by the unstable manual feeding frequency in the prior art. The feeder comprises a rack and also comprises a driving disc rotationally connected with the rack, a four indexing slot wheel rotationally connected with the rack, a first gear coaxially fixed with the four indexing slot wheel, a guide rod hinged to one end of the rack, a second gear meshed with the first gear and a work clamp connected with one end, far away from the rack, of the guide rod. The driving disc comprises a circular plate and a notch disc provided with two mutually symmetrical locking arcs; the circular plate comprises an arc section and a linear section; a first pin column and a second pin column are arranged on the position, close to the edge, of the circular plate; a third pin column is arranged at the edge of the second gear; a slideway penetrating through the guide rod is arranged in the middle of the guide rod; the third pin column slides in the slideway. A single-pole double-throw switch for controlling the rotary direction of the driving disc is arranged in the position, close to the middle of the linear section of the circular plate, on the rack. The feeder for heating the bar stock of the mini-tiller is simple in structure and strong in practicability.
