Compared with the prior art, the utility model has the following advantages: 1. by adopting the connection structure of the screw rod and the screw nut, the mechanical structure of the driving device can be simplified, and the driving device achieves the advantages of reasonable and simple structure and reliable service performance; and 2. the L-shaped structure of the sliding rack can enlarge the contact area between the sliding rack and a first guide post, prevent the sliding rack from vibrating, eliminate false signals generated by vibration of the sliding rack and increase the measuring accuracy.
Description
Technical field
The utility model relates to a kind of drive unit of surfagauge.
Background technology
Workpiece surface roughness is meant the smooth and smooth degree of surface of the work cutter trade, it is an important indicator of the various machinery part surface crudies of evaluation, therefore a high-precision surface roughness measuring instrument seems particularly important, and the drive unit of sensor is a principal element that influences the surface finish measurement precision in the measuring instrument.The drive unit of tradition roughness measuring instrument is made up of driving pulley, belt, driven pulley, gear, tooth bar and slide.Driving pulley is by driven by motor, and when electric motor starting, driving pulley drives driven pulley, the driven pulley driven gear, and the gear driven tooth bar, the rack drives slide slides measurement by the slide driving sensor on piece surface.But this drive unit is complex structure not only, and having serious defective, the vibration transfer that produces when promptly this drive unit is easily the rack-and-pinion transmission is given slide, produces the vibration spurious signal, directly influence the authenticity and the stability of measured value, influence measuring accuracy.
The utility model content
Technical problem to be solved in the utility model is the drive unit that a kind of surfagauge is provided at above-mentioned prior art, this device can be simplified the physical construction of original drive unit greatly, and can improve the stationarity of slide motion, and reduce the vibration spurious signal, improve measuring accuracy.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the drive unit of this surfagauge, it is characterized in that: comprise a pedestal, be fixed with the drive motor of a band speed reduction unit on this pedestal, the output terminal of this drive motor is connected with a screw mandrel, on this screw mandrel nut is housed, this nut is fixed on one can connect the sensor that is used to detect workpiece surface roughness along on the travelling carriage of pedestal slip on this travelling carriage.
As improvement, described travelling carriage is the L type, and first end of this L type travelling carriage slidably is arranged on first guide pillar, and this L type travelling carriage second end slidably is arranged on second guide pillar, and described first guide pillar and described second guide pillar all are fixed on the described pedestal.
Further improve, be provided with the through hole that axially runs through in the support arm of described L type travelling carriage, described first guide pillar passes this through hole and first end of described L type travelling carriage can be slided on described first guide pillar.
The end of another arm of described L type travelling carriage has L type groove, be embedded with ganoid slide head on this L type groove inwall, described pedestal and the corresponding position of described slide head are provided with a spring leaf, be equipped with one on this spring leaf and drag tight head, described second guide pillar passes this L type groove, and drag tight head to offset, thereby second end of described L type travelling carriage can be slided on described second guide pillar with described.
Compared with prior art, advantage of the present utility model is:
1, adopts the syndeton of screw mandrel, screw, can simplify the physical construction of drive unit, have characteristics such as reasonable, simple, that usability is reliable.
2, L type travelling carriage structure can increase the contact area between the travelling carriage and first guide pillar, prevents the travelling carriage vibration, eliminates because of the travelling carriage vibration produces spurious signal, improves measuring accuracy.

Fig. 2 is the sectional view of L type travelling carriage among the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The drive unit of surfagauge as shown in Figure 1, 2 comprises a pedestal 1, and pedestal 1 is the opening box body structure here; Be fixed with the drive motor 2 of a band speed reduction unit on the pedestal 1, drive motor 2 by screw retention at bottom half.The output terminal of this drive motor 2 is connected with a screw mandrel 3, on this screw mandrel 3 nut is housed, and this nut is fixed on the travelling carriage 4, connects the sensor that is used to detect workpiece surface roughness on this travelling carriage 4.This travelling carriage 4 is formed L type structure by two support arms 41,42, is provided with through hole 411, the first guide pillars 5 that axially run through in first support arm 41 of travelling carriage and passes this through hole 411, thereby first support arm 41 of L type travelling carriage 4 can be slided on first guide pillar 5; The end of second support arm 42 of travelling carriage has L type groove 421, these L type groove 421 inwalls are embedded with ganoid slide head 6, be provided with spring leaf 7 with slide head 6 corresponding positions on the pedestal 1, one drags and passes this spring leaf 7 for tight 8, second guide pillar 9 passes this L type groove, and with slide head 6 with drag tight 8 to offset, thereby second support arm 42 of L type travelling carriage 4 can be slided on second guide pillar 9.
Like this, after drive motor 2 work, when the output terminal of drive motor 2 drove screw mandrel 3 rotations, the screw on the screw mandrel 3 then drove L type travelling carriage 4 and do tangential movement on first guide pillar 5 and second guide pillar 6.
