Abstract
The invention discloses a concentricity detection mechanism for a machining center. The concentricity detection mechanism comprises a bearing used for being installed on each hole needing to be detected. The bearing of each hole is connected with a stepped shaft in a penetrating mode. Each stepped shaft is divided into a small shaft, a middle shaft and a large shaft according to the sequence from the small size to the large size of the diameter. The bearings are connected to the middle shafts in a penetrating mode. The bearings and the middle shafts are in clearance fit. One ends, close to the small shafts, of the middle shafts are provided with threads. The middle shafts are connected with nuts through the threads, wherein the nuts are used for fixing the stepped shafts. Distance rings are arranged between the nuts and the bearings and movably connected to the middle shafts in a sleeved mode. The distance rings are movably connected with end covers in a sleeved mode, wherein the end covers are used for fixing the stepped shaft to a base of the machining center. The concentricity detection mechanism further comprises a dial indicator used for detecting data of the outer sides of the large shafts. The concentricity detection mechanism is high in detection efficiency, good in effect and capable of effectively saving the production time.
Description
Technical field
The present invention relates to the right alignment testing agency in machining center field, particularly a kind of machining center.
Background technology
On machining center, there are a lot of holes, for example drive the two ends of screw mandrel of the movable workbench of machining center to be just arranged on two endoporus respectively, if the right alignment in two holes is defective, will cause screw mandrel to rotate not steady, affect the movement of worktable, also can have influence on the processing of workpiece, therefore need to detect the right alignment of two endoporus.
Current when detecting the right alignment in hole, conventionally use revolving shaft collimation method, collimation method, coordinate method, wishbone method etc., while using the right alignment in these methods detection holes, mostly need special-purpose survey instrument, and loaded down with trivial details, the consuming time length of measuring process, the requirement that can not meet batch production, detects, has hindered the raising of production efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of right alignment testing agency of machining center, its efficiency is high, easy to detect and accurate.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Liang Kong right alignment testing agency of machining center, comprise for being installed to the bearing at each place, hole of required detection, on the bearing at each place, hole, cross-under has a multidiameter respectively, every multidiameter is divided into three sections by the ascending order of diameter, these three sections are followed successively by little axle, axis and macro-axis, bearing cross-under is on axis, bearing and axis are clearance fit, described axis is provided with screw thread near one end of little axle, axis is threaded connection the nut that is useful on fixed step axle, between described nut and bearing, be provided with interval turns, interval turns is actively socketed on axis, on described interval turns, pivot bush unit is useful on multidiameter is fixed to the end cap on base, described Liang Kong right alignment testing agency also comprises the dial gauge for detection of the outer side data of macro-axis.
In the present invention, the number of bearings at each place, hole is three.
The invention has the beneficial effects as follows: on each hole, by bearing, a multidiameter is installed, first pass through wherein certain some data of the upper a certain At The Height in macro-axis outside of a multidiameter of centimeter check, then multidiameter is rotated to approximately 180 °, and then put data with the macro-axis outside of centimeter check ladder axle and certain of aforementioned sustained height place, now dial gauge is also at height and position as hereinbefore, the numerical value of twice detection is averaged, same mode detect again another root multidiameter macro-axis outside data and calculate mean value, then whether coaxial by contrasting two endoporus of two mean values, if disalignment, need again bearing seat or base to be repaired, make two endoporus coaxial.Detection efficiency of the present invention is high and effective, can effectively save the production time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention is installed to the structural representation while detecting two hole right alignmenies on endoporus.
Embodiment
As shown in Fig. 1 ~ Fig. 2, a kind of Liang Kong right alignment testing agency of machining center, comprise for being installed to the bearing 1 at each place, hole of required detection, on the bearing 1 at each place, hole, cross-under has a multidiameter 2 respectively, every multidiameter 2 is divided into three sections by the ascending order of diameter, these three sections are followed successively by little axle 3, axis 4 and macro-axis 5, bearing 1 cross-under is on axis 4, bearing 1 is clearance fit with axis 4, described axis 4 is provided with screw thread near one end of little axle 3, axis 4 is threaded connection the nut 6 that is useful on fixed step axle 2, between described nut 6 and bearing 1, be provided with interval turns, interval turns is actively socketed on axis 4, on described interval turns, pivot bush unit is useful on multidiameter 2 is fixed to the end cap 7 on base, described Liang Kong right alignment testing agency also comprises the dial gauge for detection of macro-axis 5 outer side datas.On each hole, by bearing 1, a multidiameter 2 is installed, first pass through wherein certain some data of the upper a certain At The Height in macro-axis outside of a multidiameter 2 of centimeter check, then by approximately 180 ° of multidiameter 2 rotations, and then put data with the macro-axis outside of centimeter check ladder axle and certain of aforementioned sustained height place, now dial gauge is also at height and position as hereinbefore, the numerical value of twice detection is averaged, same mode detect again another root multidiameter 2 macro-axis 5 data and calculate mean value, then whether coaxial by contrasting two endoporus of two mean values, if disalignment, need again 1, bearing or base to be repaired, make two endoporus coaxial.Detection efficiency of the present invention is high and effective, can effectively save the production time.
Further, bearing 1 quantity at each place, hole is three, can make like this multidiameter 2 place more stablely.
The above, be better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, within all should falling into protection scope of the present invention.
