Abstract
The utility model relates to the field of machine tools, and particularly discloses a positioning device for an end face of a part clamped outside a clamping jaw of a main shaft of a machine tool, wherein a mounting seat is fixed on the machine tool body, a telescopic mechanism is arranged on the mounting seat, a positioning piece which can axially extend and retract along the main shaft by the telescopic mechanism is arranged on the telescopic mechanism, when the part is clamped on the clamping jaw, the positioning piece stretches out and abuts against one side end of the part close to the clamping jaw to position the part, and after the clamping of the part is completed, the positioning piece retracts and is separated from the end face of the part; by adopting the positioning device, the positioning piece is installed and fixed on the machine tool and does not rotate along with the clamping jaw, so that the positioning piece stretches out to position the part during positioning, and the positioning piece retracts to form friction with the end face of the part during processing, so that the clamping efficiency can be improved, and the requirement of processing the end face of the outer clamping part close to one side of the clamping jaw can be met.
Description
Technical Field
The utility model relates to the field of machine tools, in particular to a part positioning device.
Background
The machine tool is mainly provided with a three-jaw chuck for clamping the parts, the parts are generally divided into an outer clamp and an inner clamp according to different parts, the inner clamp mainly clamps and fixes the periphery of the parts aiming at the parts such as bars, and the outer clamp mainly clamps the pipes or the holes from an internal support. In order to improve the machining efficiency, two end faces of the external clamping part can be clamped at one time for machining respectively, or the two end faces can be machined simultaneously, in order to leave enough machining space, the end face of the part close to one side of the clamping jaw cannot be too close to the end face of the clamping jaw or lean against the clamping jaw, the end face of the part close to one side of the clamping jaw or the end face of the follow-up positioning block is positioned when the part clamped by the external clamping part in the existing equipment, and under the condition, the part close to one side of the clamping jaw cannot be machined due to the fact that the space for accommodating a cutter and the interference of the follow-up positioning block to the cutter are not available, so that the part can be positioned by observing by workers, the efficiency is low, and the position of the clamped part can be changed every time.
Disclosure of utility model
In order to solve the problem of difficult positioning of the end face of the external clamping part in the prior art, the technical scheme adopted by the utility model is as follows:
A mounting seat is fixed on a machine tool body, a telescopic mechanism is arranged on the mounting seat, a positioning piece which can axially extend and retract along a spindle is arranged on the telescopic mechanism, when a part is clamped on a clamping jaw, the positioning piece stretches out and abuts against one side end of the part, which is close to the clamping jaw, to position the part, and after the clamping of the part is completed, the positioning piece retracts and is separated from the end surface of the part.
Further, the telescopic mechanism is an air cylinder or a hydraulic cylinder.
By adopting the positioning device, the positioning piece is installed and fixed on the machine tool and does not rotate along with the clamping jaw, so that the positioning piece stretches out to position the part during positioning, and the positioning piece retracts to form friction with the end face of the part during processing, so that the clamping efficiency can be improved, and the requirement of processing the end face of the outer clamping part close to one side of the clamping jaw can be met.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Detailed Description
The technical scheme of the utility model is further described in detail below with reference to the attached drawings and specific embodiments.
The positioning device shown in fig. 1 comprises a mounting seat 1, wherein the mounting seat 1 is fixed on a machine tool body, therefore, the mounting seat 1 cannot rotate along with a main shaft claw A, and because the positioning device is mainly used for positioning a part B by leaning against an end face C on one side of the claw, the mounting seat 1 is arranged at a position on a machine tool body, which is close to the claw, as far as possible for positioning, and a telescopic mechanism 2 is arranged on the mounting seat 1, in the embodiment, the telescopic mechanism 2 is a hydraulic cylinder or an air cylinder, a single-acting oil cylinder is preferred for simplifying the structure, namely, the hydraulic rod stretches out and stops being automatically retracted after being pressed, a positioning piece 3 is arranged on the telescopic mechanism 2, the positioning piece 3 is a piston rod of the hydraulic cylinder or the air cylinder, and an independent positioning block can be arranged at the end part of the piston rod of the positioning device as the positioning piece 3, and the telescopic mechanism 2 can drive the positioning piece 3 to stretch out or retract, and the telescopic direction of the telescopic mechanism stretches along the axial direction of the main shaft. When the part is clamped on the claw in the mode of external clamping as shown in fig. 1, the telescopic mechanism 2 drives the positioning piece 3 to extend, the part abuts against the positioning piece 3 to realize positioning by abutting against one side end face of the claw, the positioning piece 3 retracts after the clamping is completed, the positioning piece 3 does not interfere with the end face of the part when the claw drives the part to rotate, and the positioning piece 3 positions the end face of the part in an extending state, so that enough space can be reserved for the part abutting against one side end face of the claw, and the processing of the side end face is facilitated.
Claims (2)
1. The utility model provides a lathe main shaft jack catch outer clamp part terminal surface positioner which characterized in that: the machine tool comprises a machine tool body, a mounting seat (1) is fixed on the machine tool body, a telescopic mechanism (2) is arranged on the mounting seat (1), a positioning piece (3) which can axially stretch along a main shaft by the telescopic mechanism (2) is arranged on the telescopic mechanism (2), when a part is clamped on a clamping jaw, the positioning piece (3) stretches out and abuts against one side end of the part, close to the clamping jaw, to position the part, and after the clamping of the part is completed, the positioning piece (3) retracts to be separated from the end surface of the part.
