Abstract
The utility model relates to a small deep hole alignment abrasion resistant meter rod device, belonging to the small hole alignment lengthened meter rod device of rigid alloy processing industry, which comprises a meter head and an alignment meter rod of a measurement meter, wherein the front end of the meter head is provided with an abrasion resistant probe, one end of the alignment meter rod is vertically connected with the meter head and the another end is fixed with an abrasion resistant alignment probe vertical to the meter head. The small deep hole alignment abrasion resistant meter rod device has abrasion resistance, can improve measurement accuracy, can measure deep hole and has large measurement range. The utility model resolves the inner hole alignment problem of rigid alloy processing industry such as the difficult alignment of small holes whose depths are over 13mm and the low measurement accuracy caused by the abrasion on the meter head.
Description
Technical field
The utility model relates to the wear-resisting table lever apparatus of a kind of small deep hole centering, belongs to the technical field of table lever apparatus of the aperture centering lengthening of wimet processing industry.
Technical background
The lever scale degree of depth only has 13MM in the prior art, and scale range 0.2MM is if want gaging hole to surpass the then quite difficult of 13MM deeply.Existing dial gauge or clock gauge gauge head adopt tool steel to make more, and gauge head weares and teares easily, and especially in the wimet processing industry, the gauge head wearing and tearing are very fast, have influenced the accuracy of measuring.
Summary of the invention
It is a kind of not easy to wear that the utility model purpose is to provide, be beneficial to the raising measurement accuracy, but deep degree of gaging hole and all bigger wear-resisting table lever apparatus of small deep hole centering of range have solved the little hole depth that exists in the prior art and have been difficult to measure the especially problems such as endoporus centering in the wimet processing industry of centering and gauge outfit measuring accuracy difference easy to wear above 13MM.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the gauge outfit and the centering table bar of meter, described gauge outfit front end is provided with wear-resisting gauge head, described centering table bar one end with gauge outfit between vertical the connection, the described centering table bar other end is fixed with the wear-resisting centering gauge head vertical with gauge outfit.But the degree of depth and range that the utility model has enlarged sounding hole by being provided with of centering table bar, gauge head with centering gauge head and meter adopts wimet to make simultaneously, improve the wearing quality of the gauge head of centering gauge head and meter, improved the accuracy that meter is measured.
As preferably, described centering table bar cross section is T-shaped, thereby the formation reinforcement is arranged at centering table bar upside, centering table bar is stressed and do not produce amount of deflection in guarantee using, and reinforcement section and dial gauge, clock gauge motion bar place tolerance clearance is minimum, does not make centering table bar stressed back owing to its gap produces measuring error.
As preferably, described centering table bar integral body is tapered, and it is less that wear-resisting centering gauge head one end wherein is set.
As preferably, described gauge outfit also comprises first screw and second screw, the described first screw front end is threaded with the table bar of meter, the first screw rear end is provided with screw-threaded counterbore, weld between the described wear-resisting gauge head rear end and second screw head, described centering table bar is provided with through hole, and the described second screw front end passes the through hole of centering table bar and the screw-threaded counterbore threaded engagement of the first screw rear end.
Therefore, the utlity model has not easy to wearly, be beneficial to the raising measurement accuracy, but characteristics such as deep degree of gaging hole and range be all bigger.

Fig. 2 is a kind of structural representation of the utility model first screw;
Fig. 3 is a kind of structural representation of the utility model centering table bar.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the gauge outfit of dial gauge 1 comprises first screw 2 and second screw 3, wear-resisting gauge head 4, first screw, 2 front ends are threaded with the table bar 5 of meter, as shown in Figure 2, first screw, 2 rear ends are provided with screw-threaded counterbore 6, weld between wear-resisting gauge head 4 rear ends and second screw, 3 heads, as shown in Figure 3, centering table bar 7 one ends are provided with through hole 8, second screw, 3 front ends pass the through hole 8 of centering table bar 7 and screw-threaded counterbore 6 threaded engagement of first screw, 2 rear ends, centering table bar 7 with gauge outfit between vertical the connection, centering table bar 7 other ends are fixed with the wear-resisting centering gauge head 9 vertical with gauge outfit, centering table bar 7 cross sections are T-shaped, and centering table bar 7 is whole tapered, and it is less that wear-resisting centering gauge head 9 one ends wherein are set.
The utility model is in use earlier with dial gauge, and clock gauge is assembled in has deep hole centering table bar centering side head end to stretch into need centering measured place in the workpiece hole according to general lever meter, dial gauge, the operation of clock gauge centering again on the magnet stand for example.
The utility model especially when the centering endoporus is the wimet workpiece of blank, because of surface of the work is uneven, can satisfy use with general dial gauge 0-9MM range, and adopt prior art because of range generally at 0-0.20MM, very difficult, very easily damage.
