Abstract
The utility model discloses a special gauge for detecting an outer raceway of a slewing bearing. The special gauge comprises a dial indicator body (7) and a measuring head (71) thereof, and is characterized in that the gauge also comprises a fore measuring bar (1) and a rear measuring bar (2), wherein the fore measuring bar (1) and the rear measuring bar (2) are connected by an adjustable measuring bar (3), the fore measuring bar (1) is fixedly connected with a standard bulb (5) through a connecting bolt (4), the rear measuring bar (2) is connected with the dial indicator body (7) through a fastening screw (6), the dial indicator body (7) and the measuring head (71) are disposed opposite to the standard bulb (5), and the measuring head (71) and the standard bulb (5) are positioned at the same horizontal axis. The special gauge has the advantages that the problems in the prior art that auxiliary tools are needed for indirect measurement during detection and measurement for the outer raceway of the slewing bearing, detection precision is poor, and detection efficiency is low.
Description
Technical field
The utility model relates to technical field of measuring equipment, is specifically related to the outer raceway of a kind of pivoting support and detects appliance special for detecting.
Background technology
At present, swivel mounting member applies on the excavator, tower machine, large-tonnage crane of engineering machinery more, because the diameter of workpiece is large, thereby in this class part of processing, the rolling track and radial size of pivoting support is large especially on the manufacturing accuracy impact of pivoting support, because the universal check tool that the outer raceway examine of diameter of pivoting support is used can not directly be measured usually, generally need indirectly measure by aid, the precision as a result that above-mentioned detection mode detects is poor, and detect and need to could realize by aid, also affected detection efficiency.
Summary of the invention
The utility model is for the problem of above-mentioned existence, propose the outer raceway of a kind of pivoting support and detected appliance special for detecting, the utility model efficiently solves prior art raceway outside carrying out pivoting support and detects in metering process, need to indirectly measure by aid, not only accuracy of detection is poor, and the low problem of detection efficiency.
The utility model is achieved through the following technical solutions:
The outer raceway of a kind of pivoting support detects appliance special for detecting, comprise dial gauge body (7) and measuring head (71) thereof, it is characterized in that: described cubing also comprises before measurement gauge rod (1), rear sounding rod (2), before measurement gauge rod (1), rear sounding rod (2) connects by adjustable sounding rod (3), before measurement gauge rod (1) is fixed with standard bulb (5) by coupling bolt (4), rear sounding rod (2) is connected with dial gauge body (7) by trip bolt (6), dial gauge body (7) measuring head (71) arranges in opposite directions with standard bulb (5), and measuring head (71) is positioned on the same level axis with standard bulb (5).
The further Technological improvement plan of the utility model is:
Described adjustable sounding rod (3) two ends are fixedly connected with before measurement gauge rod (1), rear sounding rod (2) by set nut (8) respectively.
The further Technological improvement plan of the utility model is:
Described before measurement gauge rod (1), rear sounding rod (2) all are " L " type, and the lateral strut outside is provided with adjusts bolt (9)
The further Technological improvement plan of the utility model is:
The outer raceway external diameter of shape, size and the pivoting support of described standard bulb (5) is complementary.
The utility model compared with prior art, has following obvious advantage, the utility model adopts before measurement gauge rod, rear sounding rod to combine with adjustable sounding rod, at before measurement gauge rod one end standard bulb, rear sounding rod one end arranges dial gauge simultaneously, detects and measures the outer raceway of pivoting support, without by aid, can directly measure, not only improve measuring accuracy, and improve measurement efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises dial gauge body 7 and measuring head 71 thereof, described cubing also comprises before measurement gauge rod 1, rear sounding rod 2, before measurement gauge rod 1, rear sounding rod 2 connects by adjustable sounding rod 3, before measurement gauge rod 1 is fixed with standard bulb 5 by coupling bolt 4, rear sounding rod 2 is connected with dial gauge body 7 by trip bolt 6, dial gauge body 7 measuring heads 71 arrange in opposite directions with standard bulb 5, and measuring head 71 is positioned on the same level axis with standard bulb 5, adjustable sounding rod 3 two ends are respectively by set nut 8 and before measurement gauge rod 1, rear sounding rod 2 is fixedly connected with, before measurement gauge rod 1, rear sounding rod 2 all is " L " type, the lateral strut outside is provided with adjusts bolt 9, the shape of standard bulb 5, the outer raceway external diameter of size and pivoting support is complementary.
In conjunction with Fig. 1, sketch the course of work of the present utility model:
When detecting the metering operation, at first by standard bulb 5 by the fastening before measurement gauge rod 1 that is installed on of coupling bolt 4, adjustable sounding rod 3 two ends are respectively on be threaded before measurement gauge rod 1 and the rear sounding rod 2 by himself, and respectively by set nut 8 lockings, dial gauge body 7 is installed on rear sounding rod 2, and by trip bolt 6 lockings, before measurement gauge rod 1 and rear sounding rod 2 are separately installed with adjusts bolt 9, by adjustment, adjust the height of bolt 9, with the measuring staff that guarantees standard bulb 5 and dial gauge body 7 by the diameter of raceway.According to the size that will detect, adjust respectively the relative position of adjustable sounding rod 3 at before measurement gauge rod 1 and rear sounding rod 2, and the position of dial gauge body 7 on rear sounding rod 2, then according to the basic size that will detect size, check with general calipers, guarantee dial gauge body 7 compressed 2-3mm, and this cubing dial gauge body 7 is adjusted to zero-bit, namely can be used for measuring.During measurement, as long as this cubing is positioned in the outer raceway of pivoting support, by the reading of dial gauge body 7, can obtain the diameter of the outer raceway of pivoting support, such measurement is convenient, fast, accurate.
In sum, the utility model has reached the foregoing invention purpose.
