The utility model mainly provides a small hole depth detecting device which has simple structure, can be used to conveniently and precisely check the hole depth of precise small workpieces, and solves the technical problems in the prior art that the hole depth checking devices have complicated structure and inconvenient checking.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of aperture depth detection apparatus of accurate device.
Background technology
Processing at the machining mesopore is very common.The degree of depth in hole and diameter are two technical parameters in hole, generally adopt vernier caliper for the detection in aperture, adopt the vernier caliper location inaccurate for the detection of the degree of depth in hole, and inapplicable especially for relatively more accurate small workpiece.The patent document that detects for hole depth comprises: Chinese patent: " shoulder hole depth calibrator (CN200968846A) ", mainly form by base, gauge head, measurement axis, block, body, length bar, calibrating device, dial gauge; Body and base link together, and are provided with the measurement axis mounting hole, the dial gauge mounting hole that are parallel to each other on body, are provided with the length bar mounting hole coaxial with the measurement axis mounting hole on base; Measurement axis is installed in the measurement axis mounting hole, measurement axis is stretched out downwards from the hole, gauge head is connected the measurement axis lower end, gauge head is between body and base, dial gauge is installed in the dial gauge mounting hole, block one end is fixed on the measurement axis, and the other end is pressed on the gauge head of dial gauge, makes the gauge head of dial gauge and the gauge head of measurement axis be synchronized with the movement up and down; Upper end in measurement axis is equipped with handle, with pulling the motion that fixed handle can make the measurement axis easy on and off; Length bar, calibrating device are movable parts, and during measurement, calibrating device is used for dial gauge to zero, and length bar is used for inserting the shoulder hole of workpiece.Though this patent has disclosed a kind of pick-up unit of the shoulder hole degree of depth, its structure more complicated, member is many, proofreads cumbersomely, and detects and is not suitable for for the hole depth of the small workpiece of precision.
Summary of the invention
The utility model has mainly provided a kind of simple in structure, the aperture depth detection apparatus of the hole depth of the small workpiece that convenient accurately check and correction is accurate; Solve existing in prior technology hole depth pick-up unit complex structure, detect the technical matters of inconvenience.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of aperture depth detection apparatus, comprise dial gauge, described dial gauge is fixed on the gauge stand by support, dismountable detection head that is connected with below described dial gauge, the diameter of described detection head and aperture joining part is less than the diameter of aperture.Dial gauge and detection head are for removably connecting, improved the versatility of pick-up unit, aperture for different-diameter, the detection head of replacing different-diameter that can be corresponding, the diameter of detection head is less than the diameter in hole, after can allowing detection head stretch at the bottom of the hole, confirm that by the dial gauge of proofreading little hole depth is whether in the tolerance allowed band.Dial gauge is fixed on the gauge stand, and good stability has improved the accuracy that detects.
As preferably, below described dial gauge, be provided with threaded hole, described detection head and described dial gauge are by being threaded.Screw connection structure is stable, easy installation and removal simultaneously.
As preferably, described detection head comprises the section of being threaded that links to each other with dial gauge, and one-body molded below the section of being threaded have a construction section, and one-body molded below described construction section have a detection segment; Described construction section surface is a rubbing surface, and described detection segment is a polished rod.The section of being threaded is used for linking to each other with detection head, and construction section is used for detection head is installed in dial gauge, and the rubbing surface on the construction section is convenient to be tightened in detection head on the dial gauge, and the detection segment of polished rod form is convenient to be inserted detection segment in the hole to be detected.
As more preferably, described detection segment and aperture to be detected are clearance fit.Clearance fit makes things convenient for detection segment to insert fast in the aperture to be detected, realizes fast detecting.
As preferably, described detection head is to adopt the integrated one-piece construction of wolfram steel material.The wolfram steel fret wear is little, improves the accuracy that detects.
As preferably, described holder is provided with the workpiece fixed orifice, and described workpiece fixed orifice and workpiece external diameter are transition fit.Convenient will the detection behind the workpiece location, and the workpiece fixed orifice has a plurality ofly, selects the workpiece fixed orifice of different-diameter according to the workpiece of different size, improves versatility.
Therefore, aperture depth detection apparatus of the present utility model has following advantage: utilize the little hole depth in conjunction with the detection precision element of dial gauge and detection head, and simple in structure easy to detect; Detection head and dial gauge removably connect by screw thread, have improved the versatility of pick-up unit, can realize detecting for the aperture of different-diameter.
Description of drawings:
Fig. 1 is the overall schematic of aperture depth detection apparatus.
Fig. 2 is the front view that the detection head in Fig. 1 amplifies.
Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
Embodiment:
As illustrated in fig. 1 and 2, a kind of aperture depth detection apparatus, comprise gauge stand 1, above gauge stand 1, be fixed with dial gauge 3 by support 2, support 2 is locked on the vertical struts 4 of gauge stand by bolt, in the lower end of dial gauge 3 by the detection head 5 that has been threaded, detection head 5 is the section of being threaded 51 with the dial gauge section of joining, the section of being threaded 51 belows are the construction section 52 that has rubbing surface, it below construction section 52 polished rod detection segment 53, the diameter of polished rod detection segment 53 is 1.5mm, and detection head 5 is to adopt wolfram steel integrated.Polished rod detection segment 53 is clearance fit with aperture 9 to be detected, and convenient detection head 5 is inserted in the aperture detected the degree of depth.Be provided with workpiece fixing seat 6 on gauge stand 1, workpiece fixing seat 6 is provided with workpiece fixed orifice 7 not of uniform size, selects different workpiece fixed orifices 7 according to the diameter of workpiece 8, after workpiece is put into workpiece fixed orifice 7 and located, detects by dial gauge again.
