Abstract

The invention discloses a rotary distance measuring instrument, which comprises a base; left and right ends on the upper surface of the base are connected with a first support and a second support which are provided with horizontal through holes; a spline shaft is arranged between the two supports in a penetrating way; two ends of the spline shaft respectively passes through the two horizontal through holes; one end of the spline shaft arranged outside the second support is connected with a plane bearing of which the inside is connected with a first shaft; the outer wall of the first shaft is connected with a ball bearing; the outer wall of the ball bearing is connected with a rolling element; one end of the rolling element is connected with the side wall of the plane bearing, while the other end is connected with a contact plate; the spline shaft arranged between the second support and the plane bearing is sleeved with a spring; the spline shaft arranged between the first support and the second support is sleeved with an adjustable slide block which is connected with a reading head; and the reading head and two connecting blocks are connected with a grating digital display ruler. The rotary distance measuring instrument has the advantages of simple structure, improvement of production efficiency, conservation of production time, and accurate control of sink depth.

Description

Rotary distance measuring instrument

Technical field:

The present invention relates to a kind of measurement mechanism, particularly a kind of rotary distance measuring instrument.

Background technology:

In the harbour machinery industry, there are many large-scale workpieces all to need to carry out boring processing, and workpiece itself is because overweight excessive, common floor type boring machine can't be processed it, must make large-scale boring processing tool, boring row and unit head satisfy the processing needs of such workpiece, and these frocks uncontrollable counterbore degree of depth in the boring counterbore, want the degree of depth of control hole must be when bore hole, probably estimate earlier the length of bore hole, but must be not reach size, then boring cutter is withdrawed from, measure the degree of depth of bore hole with depth gauge rule, calculate, continue bore hole again apart from standard-sized surplus, by withdrawing constantly, measure, calculate, feed reaches given size, so not only make the dimensional accuracy of counterbore can not get guaranteeing, and the step of measuring in the bore hole process is comparatively loaded down with trivial details, makes operating efficiency reduce.

Summary of the invention:

The objective of the invention is in order to overcome above deficiency, provide a kind of simple in structure, enhance productivity, save the production time, can accurately control the rotary distance measuring instrument of the counterbore degree of depth.

Purpose of the present invention is achieved through the following technical solutions: a kind of rotary distance measuring instrument, comprise base, two ends, the base upper surface left and right sides are connected with first bearing and second bearing by bolt respectively, first bearing and second bearing all are " protruding " font, on the protruding block of first bearing and second bearing, all be provided with contiguous block, and in protruding block, all be provided with cross through hole, between first bearing and second bearing, run through and be provided with splined shaft, and two cross through hole are passed at the two ends of splined shaft respectively, splined shaft places an end in second bearing outside to be connected with plane bearing, plane bearing is internally connected with first, laterally place for first, and first outer wall is connected with ball bearing simultaneously, outer wall at ball bearing is connected with rotor, one end of rotor is connected with the sidewall of plane bearing, it is dull and stereotyped that the other end is connected with contact by bolt, place on the splined shaft between second bearing and the plane bearing and be with spring, place on the splined shaft between first bearing and second bearing and be with adjustable skid, adjustable skid is connected with read head, is connected with the grating digital readout chi on read head and two contiguous blocks.

The present invention compared with prior art has the following advantages: adjustable skid and read head move along with moving of rotor, because of boring row with contact flat board and contact and promote rotor and move, boring row's displacement all is presented on the grating digital readout chi like this, thereby realized the service behaviour of rotary type measuring instrument, so not only can accurately control the degree of depth of counterbore, and make measurement result comparatively accurate, thereby saved the production time, improved production efficiency.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is that the A-A of Fig. 1 is to structural representation;

Fig. 3 is that the B of Fig. 1 is to structural representation;

Number in the figure: 1-base, 2-bolt, 3-first bearing, 4-second bearing, 5-contiguous block, 6-cross through hole, 7-splined shaft, 8-plane bearing, first of 9-, 10-ball bearing, 11-rotor, 12-contact flat board, 13-spring, 14-adjustable skid, 15-read head, 16-grating digital readout chi.

The specific embodiment:

In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.

As Fig. 1, Fig. 2, Fig. 3 shows a kind of specific embodiment of rotary distance measuring instrument of the present invention, comprise base 1, two ends, the base 1 upper surface left and right sides are connected with first bearing 3 and second bearing 4 by bolt 2 respectively, first bearing 3 and second bearing 4 all are " protruding " font, on the protruding block of first bearing 3 and second bearing 4, all be provided with contiguous block 5, and in protruding block, all be provided with cross through hole 6, run through between first bearing 3 and second bearing 4 and be provided with splined shaft 7, and two cross through hole 6 are passed at the two ends of splined shaft 7 respectively, splined shaft 7 places an end in second bearing, 4 outsides to be connected with plane bearing 8, plane bearing 8 is internally connected with first 9, laterally place for first 9, and first 9 outer wall is connected with ball bearing 10 simultaneously, the outer wall of ball bearing 10 is connected with rotor 11, one end of rotor 11 is connected with the sidewall of plane bearing 8, the other end is connected with contact dull and stereotyped 12 by bolt, place on the splined shaft 7 between second bearing 4 and the plane bearing 8 and be with spring 13, place on the splined shaft 7 between first bearing 3 and second bearing 4 and be with adjustable skid 14, adjustable skid 14 is connected with read head 15, be connected with grating digital readout chi 16 on read head 15 and two contiguous blocks 5, in use, with dull and stereotyped 12 the positive end faces of contact near the testee rotating shaft, be about to the end that contact dull and stereotyped 12 abuts against the disconnected unit head of element to be measured, when rotating under the driving of unit head and feed system, testee advances, rotor 11 and then testee moves together, because rotor 11 is fixed on the termination of splined shaft 7 by plane bearing 8 and ball bearing 10, rotor 11 freely rotates on splined shaft 7, when the testee feeding, splined shaft 7 and the same moved further of testee, the read head 15 that splined shaft 7 drives on the adjustable skid 14 moves together, under the effect of spring 13, contact dull and stereotyped 12 is in no gap contact condition with testee all the time, so the reading on the grating digital readout chi 16 is the displacement of testee, so not only can accurately control the degree of depth of counterbore, and make measurement result comparatively accurate, thereby saved the production time, improved production efficiency.
