Abstract
The invention discloses a hydraulic expansion tire for a numerical control machine tool. The hydraulic expansion tire for the numerical control machine tool comprises a body, an expansion spring and a connection rod piece, wherein the body is connected with the machine head of the numerical control machine tool, and fixed on a machine tool spindle, the expansion spring is installed on the middle position of the right side of the body, the expansion spring and the body are connected in tapered mode, the connection rod piece is connected with a spindle connection rod in the machine tool through the expansion spring, and a connector is arranged on the connection rod piece. The hydraulic expansion tire for the numerical control machine tool solves the problem that an existing numerical control machine tool only can be clamped and positioned by an outer circle, can clamp parts which are positioned through inner holes, is rapid and reliable in expansion clamping, accurate in positioning, and high and stable in processing accuracy, improves rigidity of work pieces, stabilizes quality of products, reduces rejection rate, reduces production cost, reduces work intensity of workers, and is suitable for processing of a large batch of parts.
Description
Technical field
The present invention relates to machinery manufacturing technology field, specifically a kind of Digit Control Machine Tool hydraulic pressure expander.
Background technology
Hydraulic clip prodigiosin saves clamping and loose unloading workpiece institute's time spent time, statistics shows, hydraulic clamp compares the time that mechanical grip saves 90-95%, reduces the production cycle cycle, improve lathe service efficiency, thus add output and also just mean and reduce cost; Secondly, hydraulically operated fixture can realize very high positioning precision, and key is that clamping force keeps invariable in location and clamping process, thus ensure that the crudy uniformity under same procedure, will be very little owing to being out of shape the percent defective caused; In addition, the most applicable processing parts of hydraulically operated fixture put compact and adopt hand-operated clamping time space-constrained occasion, clamped position is in the distant place of lathe table top station people, staff is difficult to encounter, hydraulic clamp can operation is very easy solves these problems by reversal valve, and this just can realize clamping and the processing simultaneously on a clamp body of multiple part.Combined hydraulic fixture can realize the clamping of multistation, greatly improves work productivity.
But the processing characteristic of Digit Control Machine Tool is its processing mode adopts program composition automatically to run feed and complete work pieces process, adopt the clamping of hydraulic pressure automatic chuck, its feature accurate positioning, clamping rapidly, but it can only clamping some with the part of excircle orientation, the processing of part is diversified, and run into some with the part of Internal hole positioning, hydraulic pressure automatic chuck just cannot complete.
Summary of the invention
The object of the present invention is to provide a kind of Digit Control Machine Tool hydraulic pressure expander of rapid reliable, the accurate positioning of folder of rising, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of Digit Control Machine Tool hydraulic pressure expander, comprise body, rise spring and link member, described body is connected with the lathe head of a bed and is fixed on machine tool chief axis, the described spring that rises is arranged on the centre position on the right side of body, and the spring that rises is connected with body tapering, described link member is connected with lathe inner main axis pull bar by the spring that rises.
As the present invention's further scheme: described link member is provided with joint.
Compared with prior art, the invention has the beneficial effects as follows:
The invention solves the problem that Digit Control Machine Tool can only use cylindrical Set and Positioning, clamping can be carried out to the part of Internal hole positioning, rapid reliable, the accurate positioning of the folder that rises, machining accuracy is high and stable, improves the rigidity of workpiece, constant product quality, percent defective declines, reduce production cost, alleviate the labour intensity of workman, be applicable to the processing of part in enormous quantities.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1, a kind of Digit Control Machine Tool hydraulic pressure expander, comprise body 1, rise spring 2 and link member 3, described body 1 is connected with the lathe head of a bed and is fixed on machine tool chief axis, the described spring 2 that rises is arranged on the centre position on the right side of body 1, and the spring 2 that rises is connected with body 1 tapering, and described link member 3 is connected with lathe inner main axis pull bar by the spring 2 that rises, described link member 3 is provided with joint, described in rise spring 2 can according to location aperture size change.
Operationally, lathe inner main axis pull bar shrinks left by hydraulic control and drives link member 3 described Digit Control Machine Tool hydraulic pressure expander, and because body 1 is fixed on main shaft, then the spring 2 that rises can expand, and loads onto suitable aperture part rising on spring 2, will automatic tension.
The present invention can carry out clamping to the part of Internal hole positioning, determine the mutual alignment between workpiece and lathe, cutter rapidly and accurately, the positional precision of workpiece is ensured by fixture, not by the impact of workman's technical merit, boost productivity, reduce costs, use clamping workpiece of the present invention to improve the rigidity of workpiece, therefore cutting data can be strengthened, can use more than one piece, multi-station clamp clamping workpiece, and adopt efficient clamp system, these factors are all conducive to raising labour productivity and security; Constant product quality, percent defective declines, and gets rid of batch; The workman that industrial grade is lower can be arranged, significantly reduce production cost, the processing range expanding lathe uses special hydraulic clamp can change the purposes of former lathe and expand the scope of application of lathe, realize one-machine-multi-function, such as, also lathe can be changed into broaching machine by special fixture to use, to give full play to the effect of universal machine tools, the work in-process heart expands the quantity of processing parts effectively in stroke range effectively, alleviates the labour intensity of workman.
The invention solves the problem that Digit Control Machine Tool can only use cylindrical Set and Positioning, rapid reliable, the accurate positioning of the folder that rises, machining accuracy is high and stable, improve the rigidity of workpiece, constant product quality, percent defective declines, and reduces production cost, alleviate the labour intensity of workman, be applicable to the processing of part in enormous quantities.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
