Abstract
The invention belongs to the mechanical manufacture field, more particularly relates to a center frame used for shaft processing. The center frame is composed of a substrate, a base, a sleeve and a connecting disk and is characterized in that: the base is installed on the substrate and provided with an inner hole; the sleeve is arranged in the inner hole of the base and provided with an inner hole; the diameter of the inner hole of the sleeve is larger than the tactical diameter of the position of a workpiece supporting point; the central line of the sleeve is superposed with the central line of the workpiece; the connecting disk is fixed on the workpiece and connected with the sleeve. The two ends of the workpiece of the invention are withstood by a propping tip; the central line of the propping tip is superposed with the central line of the workpiece. As the workpiece is clamped in the sleeve of the base and fixed by the connecting disk, the clamping effect is good and the workpiece does not bend, thus enhancing the processing precision of the workpiece.
Description
Technical field
The invention belongs to the machining class, specifically is a kind of processing centre frame.
Background technology
In the machine-building process; run into the processing of axial workpiece through regular meeting; because in the Machining of Shaft-type Parts process, mid portion regular meeting causes difficulty of processing big because of cutting force or other external force effect bending; machining accuracy is low; at present often adopt fixing or follower rest supports, but centre frame must be a benchmark with processing excircles, when running into blank or irregularly shaped workpiece; existing centre frame just is difficult to satisfy processing request, thereby causes Machining of Shaft-type Parts to be difficult to reach high-precision requirement.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of simple and convenient, scientific and reasonable, good clamping effect, the unbending axle processing of workpiece centre frame are provided.
Technical scheme of the present invention is as follows:
A kind of processing centre frame of the present invention, constitute by base plate, pedestal, sleeve, terminal pad, it is characterized in that: pedestal is contained on the base plate, one endoporus is arranged on the pedestal, a sleeve is housed in the pedestal endoporus, an endoporus is arranged on the sleeve, the sleeve diameter of bore is greater than the tactical diameter of workpiece support point position, sleeve centerline overlaps with work centre line, and terminal pad is fixed on the workpiece, and is connected with sleeve.
Workpiece of the present invention two ends are withstood by top, top being contained on the centrre rest, and centrre rest is fixed on the base plate, and top center line overlaps with work centre line.
The present invention since with piece-holder in the sleeve of pedestal, and fix by terminal pad, two ends are withstood by top, make piece-holder effective, workpiece can be crooked, thereby improve the workpiece machining accuracy.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of processing centre frame, be made up of base plate 1, pedestal 2, sleeve 3, terminal pad 4, it is characterized in that: pedestal 2 is contained on the base plate 1, and an endoporus is arranged on the pedestal 2, one sleeve 3 is housed in the pedestal endoporus, one endoporus is arranged on the sleeve 3, and the sleeve diameter of bore is greater than the tactical diameter of workpiece 5 supporting point positions, sleeve centerline and workpiece 5 central lines, terminal pad 4 is fixed on the workpiece 5, and is connected with sleeve 3.
Withstand by top 6 at workpiece of the present invention 5 two ends, and top 6 are contained on the centrre rest 7, and centrre rest is fixed on the base plate 1, top 6 center line and workpiece 5 central lines.
Pedestal of the present invention, sleeve, terminal pad can be provided with a plurality of according to the processing needs.
The present invention is applicable to the processing with blank or irregularly shaped shaft-like workpiece.
