Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to an adjustable top plate for turning an eccentric shell, which solves the problem of processing and clamping eccentric cylinder parts. Background Art

[0002] The processing of cylindrical parts is generally completed by lathe cutting. When processing eccentric long cylindrical shells, due to their excessive extension, a one-clamp-one-top process is required to complete the process. In actual production, due to different eccentric distances of the shells or different precision requirements, it is often necessary to design special eccentric top plates of different specifications and types. The design and manufacturing cycle is long and the manufacturing cost is also high. When the product changes, the fixture will be scrapped because it can no longer be used. It is suitable for fixed products and large batch production.

[0003] The prior art is as follows: Method 1: prepare a special disk, align the outer circle of the shell, insert the disk into the inner hole of the top end of the shell in the eccentric direction, prepare the top hole, and tighten it with the top of the lathe. The top disk is scrapped because the top hole can no longer be prepared after several uses. The top hole has to be processed on a horizontal boring machine or a machining center. The top disk has a large loss and the shell has a large turnover number, resulting in high product production costs.

[0004] Method 2: Use a flat top plate to clamp the shell, put on the top plate, align the shell, and use the friction between the top plate and the shell end face to tighten the shell. Since the top end of the shell is only supported by the friction between the top plate and the shell end face, when the turning force is large or the speed is high, the centripetal force of the shell increases, and the friction of the top plate cannot limit the swing of the shell, causing the shell to loosen or fall, resulting in safety or quality accidents. Summary of the invention

[0005] The purpose of the present invention is to provide an adjustable top plate for turning eccentric shells, which can realize the processing of shells with different eccentric distances by adjusting the movement of screws and sliders, and mainly solves the processing problems of clamping, tightening and adjusting different eccentric distances for turning eccentric shells.

[0006] The present invention is achieved by adopting the following technical solutions: An adjustable top plate for turning an eccentric shell comprises a shell support plate, a slide rail seat is fixedly mounted on the shell support plate, a slider I capable of longitudinal movement is mounted on the slide rail seat, baffle plates I are symmetrically fixedly mounted on the upper and lower sides of the slide rail seat, a longitudinal adjustment screw for limiting the movement of slider I is installed on the baffle plate I; a slider II capable of transverse movement is mounted on the slider I, baffle plates II are symmetrically fixedly mounted on the left and right sides of the slider I, a transverse adjustment screw for limiting the movement of slider II is installed on the baffle plate II; a top hole is provided in the middle of the slider II.

[0007] Further preferably, the four corners of the slide rail seat are fixed to the shell support plate by screws respectively.

[0008] Further preferably, the baffle plate I is fixedly mounted on the upper side or the lower side of the slide rail seat by screws; the longitudinal adjustment screw passes through the baffle plate I by threads to limit and tighten the slide block I.

[0009] Further preferably, the baffle II is fixedly installed on the left side or right side of the slider I by means of screws; the lateral adjustment screw passes through the baffle II by means of threads to limit and tighten the slider II.

[0011] Further preferably, a transverse guide groove is provided on the surface of the slider I, and a transverse guide boss matching with the transverse guide groove is provided on the bottom surface of the slider II.

[0012] During operation, a slide rail seat is fixed on the support plate of the shell, and a longitudinal guide groove is opened on the slide rail seat. There are threaded holes at both ends of the longitudinal guide groove for fixing baffle I. The bottom of slider I is designed with a longitudinal guide boss that matches the longitudinal guide groove, and at the same time, a transverse guide groove that is cross-shaped with the longitudinal guide boss is designed on its top to realize adjustment and movement in two vertical directions. There are threaded holes at both ends of the transverse guide groove of slider I for fixing baffle II. The bottom of slider II is designed with a transverse guide boss that matches the transverse guide groove of slider I, and a top hole for tightening the top of the lathe is designed at the center position of its top. Baffle I and baffle II are designed with oblong holes for fixing screws themselves and threaded holes that cooperate with the adjusting screws to push sliders I and II to move. The longitudinal adjustment screw and the transverse adjustment screw are used to push sliders I and II to move perpendicularly to each other along the direction of the guide groove that matches them, so as to realize eccentricity adjustment. Further preferably, the slider I is provided with two longitudinal oblong holes located on the same longitudinal line, and longitudinal fastening screws are passed through the longitudinal oblong holes. The longitudinal fastening screws are screwed on the slide rail seat through threads to achieve positioning of the slider I.

[0013] Further preferably, the slider II is provided with two transverse oblong holes located on the same transverse line, and transverse fastening screws are passed through the transverse oblong holes. The transverse fastening screws are screwed on the slider I through threads to achieve positioning of the slider II.

[0014] When slider I and slider II are adjusted to appropriate positions, the longitudinal adjustment stroke of slider I is less than the length of the longitudinal oblong hole thereon, and the transverse adjustment stroke of slider II is less than the length of the transverse oblong hole thereon.

[0017] (2) The present invention is designed with an inner stopper installed in the eccentric hole of the shell. When the rotation speed is high and the cutting is large, the shell will not swing or fall because the inner hole is limited by the top plate stopper, thereby improving the safety factor of the processing process and better ensuring the stability of the shell processing quality.

[0018] The present invention is reasonably designed and has a modular structure. The top plate can be replaced according to different shell inner diameters; the slide rail assembly can be replaced according to different eccentricities to meet the turning processing of shells with different shell apertures and different eccentricities. In addition, the slide rail assembly has a simple structure and is easy to process and manufacture, and has good practical application value. BRIEF DESCRIPTION OF THE DRAWINGS
