Abstract
The utility model discloses a measuring head which is applied to a plane thickness measuring instrument. The measuring head comprises a head casing, a connection rod and a test head, wherein a cross section of the test head is in a runway shape, a guiding device for pulling the test head to rotate is arranged in the head casing, a groove is arranged at the front end of the head casing, the test head is arranged in the groove, the upper portion of the groove is in a ring shape and attached to the circumferential curved surface of the test head, the bottom of the groove is in a cube shape, the upper portion of the test head extends out of the outer portion of the groove, and the bottom of the test head extends into the cube-shaped bottom of the groove. The measuring head is simple in structure and easy to assemble, and the test head can rotate around an angle of 360 degrees and tilt simultaneously, so that the testing head can be closely attached to uneven surfaces of measuring products, the measuring speed is increased, and the test head is not easy to separate from the head casing due to the pulling of the guiding device when the test head tilts.
Description
Technical field
The utility model relates to a kind of measuring head, is specifically related to a kind of measuring head that is applied in the planar thickness measurement instrument.
Background technology
Half tone is claimed " screen ", " screen ", " netting twine version ", the optical tooling that photomechanical production is used again.Grenadine is divided into wire netting and chemical fibre net, and its title call has screen cloth, grenadine, silk screen etc., and specification is various, and is of many uses.Accurately measure the thickness of half tone grenadine and need use comparatively accurate thickness measure instrument.Since half tone grenadine surface irregularity, the measuring head of using in the existing thickness measure instrument, and its measuring head can not rotate rotation, can not fit with the surface of half tone grenadine well, shown in accompanying drawing 4, so measuring accuracy is not high.
The utility model content
The purpose of the utility model is to provide a kind of measuring head, and this measuring head is applied in the planar thickness measurement instrument, can fit tightly with the surface of test product, improves measuring accuracy.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of measuring head comprises head capsule, connecting link and measuring head.Measuring head adopts metal material to process, and its xsect is track shape, and its upper and lower plane is parallel to each other, is circular flat, and the side is a peripheral curved.The guide piece that the built-in pull test head of head capsule rotates.
The front end of said head capsule is provided with groove, and measuring head places said groove.Because the side of measuring head is a peripheral curved, measuring head can 360 ° of rotations in groove.
The top of said groove is annular; The bottom is the square bodily form; The top of groove and the peripheral curved of measuring head are fitted and the outside of groove is stretched out and the bottom of the square bodily form of groove is stretched in the bottom of measuring head in the top of measuring head, make that measuring head can be outward-dipping in rotation or slope inwardly.
Preferably, be provided with cavity in the head capsule, guide piece places said cavity.
Preferably, the shape of cavity and the shape of guide piece are complementary, and make guide piece in cavity, be difficult for rocking displacement.
Preferably, said guide piece is a magnet.
Preferably, said connecting link is fixed on the rear end of head capsule.
The beneficial effect of the utility model is:
1, measuring head can tilt in 360 ° of rotations, and measuring head can be fitted tightly with the surface of the measurement products of surface irregularity, measures several times thereby improve;
2, measuring head receives the traction of guide piece when tilting, and is not easy to break away from head capsule;
3, assembling easily.
Description of drawings
Fig. 1 is the structural representation of a kind of measuring head of the utility model;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the fundamental diagram of the utility model;
Fig. 4 is the instrumentation plan of the existing irregular grenadine of measuring head surface measurements.
Embodiment
Below in conjunction with accompanying drawing and practical implementation example a kind of measuring head of the utility model is done further explain, so that the clear technical scheme of understanding the utility model.
Like Fig. 1, shown in 2, the measuring head 3 that the measuring head of the utility model comprises head capsule 1, is fixed on the connecting link 2 of head capsule 1 rear end and places head capsule 1 front end.Head capsule 1 adopts stainless steel to process, and is sturdy and durable, is difficult for impaired.Measuring head 3 adopts metal material to process, and its xsect is track shape, and promptly its upper and lower plane is parallel to each other, is circular flat, and the side is a peripheral curved.The front end of head capsule 1 is provided with the groove 12 that can hold measuring head.The top of groove 12 is annular, and the bottom is the square bodily form.When measuring head 3 places groove 12; The peripheral curved of the top of groove 12 and measuring head 3 is fitted; The outside of groove is stretched out on the top of measuring head 3, and the bottom of the square bodily form of groove 12 is stretched in the bottom of measuring head 3, and measuring head 3 also can be tilted to groove outside or inside grooves in rotation.
In head capsule 1, be provided with a cavity 11, cavity 11 is pressed close to the bottom of groove 12 mutually, cavity 11 built-in guide pieces 4.Said guide piece 4 is a magnet.When measuring head 3 when groove outside or inside grooves tilt, 4 pairs of measuring heads of guide piece produce traction, make measuring head return to the origin-location.The shape of the shape of cavity 11 and guide piece 4 is complementary, and makes guide piece place cavity can not rock displacement, and the position is firm.
As shown in Figure 3, the principle of work of the utility model is following:
Connecting link 2 is connected in the thickness measure instrument, makes the thickness measure instrument can promote connecting link 2 and advances, and advances thereby promote measuring head, makes measuring head 3 press close to product 5 to be measured; When the surface irregularity of product 5 to be measured, when being not level and smooth plane; The bottom of measuring head 3 contacts at the A point with product 5 to be measured; Form certain included angle, at this moment, the A point produces reacting force F to measuring head 3; Make the outer inclination of measuring head 3 to groove, the surface of the surface of measuring head 3 and product to be measured 5 fits tightly.
Above-mentioned embodiment is merely the preferred implementation of the utility model; Can not limit the protection domain of the utility model with this, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement all belong to the utility model scope required for protection.
