Abstract
The utility model relates to a dial indicator, in particular to an idler wheel type dial indicator measuring head, comprising a connecting rod, a rectangular bearing frame made of metal, a miniature bearing and a pin shaft, wherein the connecting rod is a bolt with a nut in middle; an inner screw hole is arranged at the upper end part of the bearing frame, and an opened rectangular groove is arranged at the lower end part of the bearing frame; through holes are arranged in two side walls of the opened rectangular groove; the bearing frame is connected at the lower end of the connecting rod by threads; and the pin shaft penetrates through the through holes at the lower end of the bearing frame so as to insert the miniature bearing in the opened rectangular groove at the lower end of the bearing frame. As the miniature bearing replaces a sphere with high hardness which can only slide to be as the measuring head in the dial indicator, the surface of a workpiece with lower hardness is not scratched when the workpiece is detected.
Description
Technical field
The utility model relates to dial gauge, particularly roller type dial gauge measuring head.
Background technology
The measuring head of the normally used dial gauge of people is the spheroid of a high rigidity, in measuring process, can produce sliding friction between measuring head and the measured workpiece, just might the scuffing of damaging property when the measured object skin hardness is low.
Summary of the invention
The problem that the utility model will solve is: change the measuring head of dial gauge into rotatable miniature bearing, change the sliding friction that produces in the measuring process into rolling friction, avoid the scuffing of measured surface.
The technical scheme of the utility model is: a kind of roller type dial gauge measuring head; Comprise connecting link, it is characterized in that, also comprise metal rectangular bearing bracket stand, miniature bearing and bearing pin; Described connecting link is the bolt that a centre has nut; Said bearing bracket stand upper end is provided with inner bolt hole, and the bottom is provided with opening rectangular channel, is respectively equipped with through hole in the two side of said opening rectangular channel; Bearing bracket stand adopts thread connecting mode to be connected the lower end of connecting link, and the through hole that said bearing pin passes the bearing bracket stand lower end is set in miniature bearing in the opening rectangular channel of bearing bracket stand lower end.
Owing to the measuring head in the dial gauge has been replaced the high rigidity spheroid that can only slide with rotatable miniature bearing, even the lower workpiece of measurement hardness can not cause surface of the work to be scratched yet.

Fig. 2 is the side view of the utility model.
Embodiment
With reference to figure 1, Fig. 2; Roller type dial gauge measuring head comprises connecting link 1, also comprises metal rectangular bearing bracket stand 2, miniature bearing 3 and bearing pin 4; Connecting link 1 is the bolt that a centre has nut 1-1; Bearing bracket stand 2 upper ends are provided with inner bolt hole 2-1, and the bottom is provided with opening rectangular channel 2-2, is respectively equipped with through hole 2-3 in the two side of said opening rectangular channel 2-2; Bearing bracket stand 2 adopts thread connecting mode to be connected the lower end of connecting link 1, and the through hole 2-3 that bearing pin 4 passes bearing bracket stand 2 lower ends is set in miniature bearing 3 in the opening rectangular channel 2-2 of bearing bracket stand 2 lower ends.
During measurement, the upper end of the connecting link 1 of roller type dial gauge measuring head is screwed into the lower end of dial gauge sounding rod 5, adjusts the nut 1-1 on the locking connecting link 1 behind the measuring head position, can implement to measure.
