Abstract
The invention discloses a tooling for measuring hardness of a clamping piece. The tooling includes a hardness testing pedestal which is installed on a hardness meter elevating mechanism. An adjustable positioning block is rotatably installed on a center of the hardness testing pedestal. A cross section of the adjustable positioning block is in the shape of a reversed T. An upper end surface of a top plate of the adjustable positioning block is provided with a conical surface which is matched with the taper of the clamping piece. A left adjustable bearing and a right adjustable bearing are symmetrically arranged on the hardness testing pedestal and are fixed on the hardness testing pedestal through locking nuts. Upper ends of the left adjustable bearing and the right adjustable bearing are fixed to a lower end surface of the adjustable positioning block. A support is installed at external sides of the left adjustable bearing and the right adjustable bearing. A gradienter is installed on the support in a vertically sliding manner. The tooling is novel and reasonable in structure design, can allow an inclination degree of the adjustable positioning block to be adjusted freely according to an operation requirement, can allow clamping pieces in different tapers to be detected at the same time, is wide in application scope, can greatly increase work efficiency and meanwhile can reduce production cost.
Description
technical field:
The present invention relates to prestressed anchor and detect processing, relate in particular to a kind of frock of measuring intermediate plate hardness.
background technology:
At present, the prestressed anchor industry development of China is rapid, very strict to the quality requirements of the matching used intermediate plate of ground tackle.In intermediate plate production run, skin hardness has important impact to intermediate plate quality, therefore measure fast and accurately clip surface hardness, for controlling clip surface consolidation degree, prevent that clip surface defect from causing the impact in work progress to play an important role such as stripped thread, come off etc.
In recent years, along with China's rapid development of economy, the construction of high-speed traffic system and the construction of large bridge, the application of prestressed anchor, intermediate plate is more and more extensive, the surveying instrument equipment of the skin hardness to intermediate plate is a lot, on market, use and have more widely Rockwell hardometer, Brinell tester, Wechsler hardness tester etc., every kind of instrument and equipment has many unfavorable factors to affect the work efficiency of its measurement in use.But the intermediate plate that has different taperings on market as: 7 ° 10 ', 6 ° 45 ', 6 ° 30 ' etc., the various complexity of frock that surveying instrument is used, for this situation running in testing process, need to research and develop a kind of frock of measuring intermediate plate hardness that is applied to, its can free adjustment tapering to facilitate staff to detect the intermediate plate of different taperings, effectively improved work efficiency.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide a kind of frock of measuring intermediate plate hardness, structural design novelty, can be according to the gradient of the adjustable locating piece of need of work free adjustment, the intermediate plate that can simultaneously detect different taperings, usable range is wide, has greatly improved work efficiency.
Technical scheme of the present invention is as follows:
Measure the frock of intermediate plate hardness, comprise being installed on and beat hardness base on sclerometer elevating mechanism, it is characterized in that: the described hardness base center rotating of beating is provided with adjustable locating piece, adjustable locating piece cross section is inverted T-shaped, the top board upper surface of adjustable locating piece is provided with the conical surface matching with intermediate plate tapering, described beating is symmetrically distributed with left adjustable support on hardness base, right adjustable support, left adjustable support, right adjustable support lower end is fixed on and is beaten on hardness base by set nut, the lower surface of upper end and adjustable locating piece fixes, described left adjustable support, right adjustable support outside is provided with support, on support, slide up and down level meter is installed.
The frock of described measurement intermediate plate hardness, is characterized in that: described support is the guide pole longitudinally distributing.
The frock of described measurement intermediate plate hardness, is characterized in that: longitudinal plate lower end of described adjustable locating piece is set in along front and back to be run through on the bearing pin of beating hardness base, and adjustable locating piece planar swings along bearing pin.
The frock of described measurement intermediate plate hardness, is characterized in that: described left adjustable support, right adjustable support lower end are fixed on and are beaten on hardness base by set nut.
Advantage of the present invention is:
Structural design of the present invention is new reasonable, can, according to the gradient of the adjustable locating piece of need of work free adjustment, can detect the intermediate plate of different taperings simultaneously, and usable range is wide, has greatly improved work efficiency, has also reduced production cost simultaneously.
brief description of the drawings:
Fig. 1 is structural representation of the present invention.
embodiment:
Referring to accompanying drawing:
Measure the frock of intermediate plate hardness, comprise being installed on and beat hardness base 3 on sclerometer 1 elevating mechanism 2, beat hardness base 3 center rotatings adjustable locating piece 4 is installed, adjustable locating piece 4 cross sections are inverted T-shaped, the top board upper surface of adjustable locating piece 4 is provided with the conical surface matching with intermediate plate 5 taperings, beat on hardness base 2 and be symmetrically distributed with left adjustable support 6, right adjustable support 7, left adjustable support 6, right adjustable support 7 lower ends are fixed on and are beaten on hardness base 2 by set nut 8, the lower surface of upper end and adjustable locating piece 4 fixes, left adjustable support 6, right adjustable support 7 outsides are provided with support 9, on support 9, slide up and down level meter 10 is installed.
Support 9 is the guide pole longitudinally distributing.
Longitudinal plate lower end of adjustable locating piece 4 is set in along front and back to be run through on the bearing pin 11 of beating hardness base, and adjustable locating piece 4 planar swings along bearing pin 11.
Testing process is as follows: while detecting clip surface hardness, by the surperficial wiped clean of intermediate plate 5, be placed on adjustable locating piece 4, two side stands 9 are contained in respectively in the pilot hole of beating hardness base 3 two ends, level meter is set on support 9, adjust left adjustable support 6 simultaneously, right adjustable support 7 makes the tapering of adjustable locating piece 4 be applicable to the intermediate plate of different taperings, thereby make intermediate plate 5 upper end maintenance levels, whether recycling level meter 10 detects level, after level, contact with penetrator 12 and (note: during near penetrator 12, answer rising worktable, must not impact pressure head), make penetrator 12 keep vertical with level meter 10, now detect the skin hardness of intermediate plate according to scleroscopic normal running code.
