Abstract
The utility model discloses a machine tool automatic fixture, and belongs to the field of clamping parts of machine tool workpieces. The workpieces in the prior machine tool fixtures are easy to deform, bad in stability and the like. The machine tool automatic fixture comprises a base, a sliding mechanism and a fixture device; the sliding mechanism comprises a drive mechanism and a sliding block; the drive mechanism is placed on the base, and a sliding block is placed on a piston rod of the drive mechanism through a connection block; and a horn-shaped sliding rail is placed on the top surface of the sliding block. A guide rod is placed on the sliding rail; the fixture device is divided into a connecting rod and chucks; one end of the connecting rod is connected with the guide rod, and the other end of the connecting rod is fixedly connected with the chucks; the side walls, close to the insides, of two chucks are placed to be circular-arc-shaped; and the guide rod slides in the sliding rail to achieve opening and closing of the chucks, and when the chucks are in a closing state, the distance between the two chucks equals to the diameters of the workpieces. Because the horn-shaped sliding rail placed on the sliding block changes stress directions of the workpieces, the condition that the workpieces deform and the like is avoided, and stability of the workpieces is improved.
Description
Technical field
The utility model belongs to Machinetool workpiece and clamps field of components, and is relevant with a kind of lathe automatic fixture.
Background technology
Tradition motorcycle vibration absorber aluminum pipe is often processed processing to the aluminum pipe end face adding man-hour needs, or to tail end boring etc., existing lathe adds man-hour to this class bar part, usually with Workpiece clamping on the V-arrangement fixture, then by cutter, it is processed, yet existing fixture easily causes workpiece deformation because active force is too large, and the stability for processing work is not high, has reduced the product quality of aluminum pipe.
The utility model content
The purpose of this utility model be exactly to solve that existing jig exists easily make processing work distortion, the not high defective of workpiece stability, a kind of good stability is provided and does not allow yielding lathe automatic fixture.
for this reason, the utility model is by the following technical solutions: a kind of lathe automatic fixture, it is characterized in that, described lathe automatic fixture comprises base, slipping mechanism and grip device, slipping mechanism comprises driving mechanism and slide block, driving mechanism is fixedly installed on base, slide block is fixedly installed on the driving mechanism piston rod by contiguous block, the end face of described slide block arranges tubaeform slideway, guide post is set respectively on slideway, grip device is made as two parts, comprise respectively connecting rod and chuck, one end of connecting rod is connected with guide post, the other end is fixedly connected with chuck, two inner sidewalls of chuck are made as circular arc, guide post slides in slideway, drivening rod slides together, realize the opening and closing between chuck, when closure state, distance between the circular arc bottom of two chucks is suitable with the diameter of workpiece.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described driving mechanism is hydraulic jack.
Described grip device is provided with two, lays respectively at afterbody and the middle part of piston rod.
Described base is provided with two automatic fixtures, can simultaneously two workpiece be processed simultaneously, has improved operating efficiency.
Described base is provided with protective cover, and protective cover is closed in slide block and piston rod in protective cover, prevents that the aluminium bits of workpiece from entering.
Described leading section setting is fixedly installed on protective cover against plate against plate, on plate, the conflict head is set, and the head of conflicting is corresponding with the center of chuck, and the end of workpiece is resisted against on the head of conflicting.
The utility model compared with prior art has the following advantages: the utility model is by arranging tubaeform slideway on slide block, due to fixture in travel engineering, slideway has changed the force direction that is subjected to workpiece, in the process of Workpiece clamping, the situations such as distortion can not appear in workpiece, and increased the stability of workpiece, improved the product quality of workpiece.
