Abstract
The invention discloses a parallelism detection device, belonging to the technical field of parts error detection. The parallelism detection device comprises a measuring head, a scale, a connecting plate and a bridge plate. The measuring head contacts a left bus of a lead screw, and a locking screw is arranged below the measuring head. When being positioned, the measuring head is locked by the locking screw. The measurement surface of the scale contacts an upper bus of the lead screw, and a vernier digital display ruler sleeves the rod part of the scale. The parallelism error between the upper bus of the lead screw and a bed way is read out by the vernier digital display ruler. The vernier digital display ruler and the bridge plate are connected via the connecting plate and a screw. During detection, the whole device can move along the axial direction of the lead screw, so that the parallelism between the whole axial direction of the lead screw and the bed way can be detected. The parallelism detection device designed by the invention is simple to manufacture and convenient to use, is of high measurement precision, and can detect the parallelism errors between the upper and side buses of the longitudinal lead screw and the surface of the bed way simultaneously.
Description
Technical field
The present invention relates to part error detection technique field, particularly relate to a kind of Parallel testing utensil.
Background technology
Along with the development of mechanical industry; for the shape of part and the requirement of site error more and more higher; therefore mechanically there is the testing tool of the Form and position error of various part; when detection key element above part increases; traditional detection utensil often needs to go respectively to detect different key elements; such meeting is lost time especially; detection utensil traditional in addition, after determining reference field, usually can cause the increase of measuring error due to problems such as the mismatch errors between the reference element of utensil itself and workpiece benchmark.
Summary of the invention
Object of the present invention is exactly need to detect respectively to the multiple key elements on part to overcome the traditional detection utensil of prior art, the defect of losing time, devise a kind of Parallel testing utensil, measuring accuracy is high, can detect the parallelism error in longitudinal screw mandrel Up Highway UHW and side bus and bed ways face simultaneously.
The required technical matters solved of the present invention can be achieved through the following technical solutions:
A kind of Parallel testing utensil, comprise measuring head, scale, web joint, bridge plate, described measuring head contacts with the left side bus of screw mandrel, and the measuring surface of described scale contacts with the Up Highway UHW of screw mandrel, is connected between vernier digital display rule with described bridge plate by described web joint and screw.
The left side of described measuring head is provided with a dial gauge.
The below of described measuring head is provided with a lock-screw.
Bar portion cover above described scale has a vernier digital display rule.
The below of described bridge plate is provided with two guide-track grooves and fits with the guide rail of two on lathe bed respectively.
Owing to have employed above technical scheme, tool of the present invention has the following advantages:
Adopt the composite design of measuring head, scale, web joint, bridge plate, this Parallel testing utensil, make simple, easy to use, directly fit with the guide rail of two on lathe bed respectively with two guide-track grooves of the below of bridge plate and detect the parallelism error of bed ways and screw mandrel bus, measuring accuracy is high, utilizes the mode of the combination of digital display rule and dial gauge, can detect the parallelism error in longitudinal screw mandrel Up Highway UHW and side bus and bed ways face simultaneously.

Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A kind of Parallel testing utensil, comprise measuring head 1, scale 4, web joint 6, bridge plate 8, measuring head 1 contacts with the left side bus of screw mandrel 10, the measuring surface of scale 4 contacts with the Up Highway UHW of screw mandrel 10, be connected by web joint 6 and screw 7 between vernier digital display rule 5 with bridge plate 8, during detection, whole device can move axially along screw mandrel 10, reaches the object of the depth of parallelism detecting the whole axis of screw mandrel 10 and bed ways 9.
The left side of measuring head 1 is provided with a dial gauge 3, and when the pressure between measuring head 1 and screw mandrel 10 changes, the pointer on dial gauge 3 deflects, thus reads the parallelism error of bus and bed ways 9 on the left of screw mandrel 10.
The below of measuring head 1 is provided with a lock-screw 2, after the position of measuring head 1 is decided, with lock-screw 2 by locked for its position, ensure that the accuracy of measurement.
Bar portion cover above scale 4 has a vernier digital display rule 5, and the parallelism error of screw mandrel 10 Up Highway UHW and bed ways 9 is then read by vernier digital display rule 5.
The below of bridge plate 8 is provided with two guide-track grooves and fits with the guide rail of two on lathe bed respectively.
Parallel testing utensil designed by the present invention, make simple, easy to use, directly fit with the guide rail of two on lathe bed respectively with two guide-track grooves of the below of bridge plate 8 and detect the parallelism error of bed ways 9 and screw mandrel 10 bus, measuring accuracy is high, utilize the mode of the combination of digital display rule and dial gauge, the parallelism error in longitudinal screw mandrel Up Highway UHW and side bus and bed ways face can be detected simultaneously.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
