Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
As shown in Figure 1, 2, positioner of the present invention comprises positioning seat 1, the lower surface of positioning seat 1 is provided with the groove 11 suitable with the guide rail top surface shape of lathe, the lower surface of positioning seat 1 is also provided with the protuberance 13 to downward-extension, protuberance 13 is provided with at least one tapped blind hole, through hole 12 is provided with, the axis of through hole 12 and the axis being parallel of groove 11 on the top of tapped blind hole.The end face of positioning seat 1 is provided with the stepped hole 14 through with through hole 12, and the upper end of stepped hole 14 is provided with thread segment.
Locating pin 2 is provided with in stepped hole 14.As shown in Figure 3, locating pin 2 is provided with flange collar 21, and locating pin 2 is divided into long section 22 and short section 23, is provided with threaded portion 221 at the free end of long section 22.As shown in Figure 2, the flange collar 21 of locating pin 2 is resisted against on stepped hole 14, the long section 22 of locating pin 2 is from bottom to top coated with spring 8, screw 4 and nut 3 successively, the center of screw 4 is provided with the through hole passed for locating pin 2, the external screw thread of screw 4 is threaded with the thread segment of stepped hole 14, the center of nut 3 is provided with the internal thread with threaded portion 221 adaptation of locating pin 2, and is threaded with threaded portion 221.
As shown in Figure 4, alignment pin 7, in cylindric, alignment pin 7 is provided with at least two locating slots 71 along its length.As shown in Figure 2, alignment pin 7 is installed in the through hole 12 of positioning seat 1, and the opening of locating slot 71 is towards stepped hole 14, and the end of short section 23 of locating pin 2 is inserted in a locating slot 71 of alignment pin 7, and therefore alignment pin 7 is fixed in positioning seat 1.The length of alignment pin 7 is greater than the length of through hole 12.
As shown in Figure 1, 2, be provided with clamp 5 in the bottom of the protuberance 13 of positioning seat 1, be fixedly connected with positioning seat 1 in the tapped blind hole being arranged on positioning seat 1 by bolt 6.As shown in Figure 1, on the direction of the axes normal with groove 11, the length of clamp 5 is greater than the length of protuberance 13.
Guide rail end face because of most of lathe is V-type, and therefore groove 11 can be V-type groove.In the present embodiment, positioning seat 1 is provided with two tapped blind holes.As shown in Figure 2, alignment pin 7 is provided with two locating slots 71.
When positioner is arranged on lathe, according to predetermined processing dimension, positioning seat 1 is placed on the relevant position of guide rail end face of lathe, groove 11 is coincide with guide rail; Then below the protuberance 13 clamp 5 being placed on positioning seat 1, clamp 5 is made to be resisted against (sidewall below guide rail inwardly concaves relative to the lateral surface of guide rail) on the lower surface of lathe guide rail, make the guide rail clip of lathe be located at clamp 5, between groove 11 and the side of protuberance 13, and by being threaded between clamp 5 with protuberance 13 positioner to be fixed on the guide rail of lathe.Meanwhile, also can suitably change according to processing dimension the locating slot that alignment pin 7 is connected with locating pin 2, to adjust the length that alignment pin 7 stretches out relative to positioning seat 1.
Because the end of alignment pin 7 is outwardly and towards the planker of lathe relative to positioner, in process, when planker along slide to alignment pin 7 against time, illustrates that workpiece is machined to predetermined processing dimension, can stop processing.In batch production, after processing unit one, examine processing dimension, if processing dimension is qualified, same a collection of workpiece afterwards all with the installation site of positioner for object of reference is processed.
The planker of lathe is generally plane towards the side of positioner.Preferably, if the side of planker is not plane, on planker, the projection that protrudes from this side can be set on the side of positioner, the end face of this projection is first resisted against on alignment pin than other positions of this side, before processing, mounting and positioning device is carried out again in the fixed position that the concrete Size calculation with reference to this projection goes out positioner.
The present invention is mounting and positioning device on machine tool, eliminates workman in batch production and repeatedly monitors the difficulty of less scale, ensure that crudy, improve working (machining) efficiency simultaneously.
Be only several specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
