Description
Technical field:
The utility model relates to the used measurer of a kind of machine tooling, and especially the end face shallow bore hole is measured measurer.
Background technology:
Along with the development of society, technology constantly improves, and equipment manufacture is more and more higher to the requirement of processing machine tool lathe.Because the development of heavy industry, the size of the parts of equipment is increasing, thereby needs the portable serial lathe of large-scale machining tool, especially large-sized gantry.The portable serial lathe of large-sized gantry all is furnished with machine tool accessories, to enlarge the range of work of lathe.And the body of milling head end face of machine tool accessories often has some endoporus bigger, and the degree of depth more shallow (as dark 5mm), and precision prescribed is higher, and it is very big to measure difficulty, directly influences the precision of processing work.Measuring certain body of milling head diameter of phi 360H6, dark 5, the hole of circularity 0.02 is an example, and precision prescribed is higher, must measure dimensional accuracy, also will measure circularity.Traditional measuring method is to utilize micrometer inside caliper, carries out hole measuring, but because this hole is more shallow, the side head of common micrometer inside caliper can not effectively contact hole wall, can not realize effective measurement.A conventional tittle cubing also all can't be measured it accurately.
The utility model content:
In order to solve the existing very big problem of the more shallow hole measuring difficulty of measurer measuring junction face, the utility model provides a kind of end face shallow bore hole to measure measurer, this end face shallow bore hole measure measurer have the more shallow hole measuring of the end face of measurement accurately and reliably, the precision height, the characteristics that measuring operation is easy.
The technical solution of the utility model is: this end face shallow bore hole is measured measurer and is comprised the dial gauge gauge outfit, is made up of pin, compression spring, sliding axle, left and right measurement claw, table bar, tubular gauge rod, fixed cover substantially; The dial gauge gauge outfit places in the fixed cover termination, and passes through screw retention; Fixed cover is fixedlyed connected with gauge rod by screw thread; The gauge rod left end is built-in with the table bar, and table bar left end contacts with dial gauge gauge outfit contact; A left side measure claw pass on the gauge rod strip hole by screw thread with show bar and fixedly connected; Compression spring is enclosed within a left side and measures on the claw right-hand member gauge rod, and two ends are stuck on pin and the gauge rod inner step; Sliding axle places in the gauge rod right-hand member; The right claw of measuring passes the gauge rod right-hand member and is connected on the gauge rod by packing ring and fixed by nut behind the via hole on corresponding strip hole and the sliding axle up and down.
Gauge rod right-hand member plug in the such scheme is by being threaded; Left and right measurement claw lower end is respectively spherical.
The utlity model has following beneficial effect: this end face shallow bore hole is measured measurer and is measured claw and the right claw inner blocking type of measuring because of adopting a left side, the structure that the table bar touches dial gauge gauge outfit contact, registration by dial gauge changes, thereby can accurately measure the dimensional accuracy and the circularity of endoporus.Thereby solved the shallow hole measuring poor accuracy of end face, precision is low, the measuring operation complicated problems has improved working (machining) efficiency, provides technical guarantee for producing high quality of products.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-dial gauge gauge outfit among the figure, the 2-fixed cover, the 3-gauge rod, 4-shows bar, and 5-measures claw in a left side, right claw, 7-sliding axle, 8-compression spring, the 9-pin measured of 6-.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this end face shallow bore hole is measured measurer and is comprised dial gauge gauge outfit 1, is made up of pin 9, compression spring 8, sliding axle 7, left side measurement claw 5, right measurement claw 6, table bar 4, tubular gauge rod 3, fixed cover 2 substantially; Dial gauge gauge outfit 1 places in fixed cover 2 terminations, and passes through screw retention; Gauge rod 3 left ends reach right-hand member down all strip hole up and down, and step hole is arranged in gauge rod 3 left ends, and gauge rod 3 right-hand member plugs are by being threaded, and gauge rod 3 is fixedlyed connected with fixed cover 2 by screw thread; Gauge rod 3 left ends are built-in with table bar 4, and table bar 4 left ends contact with dial gauge gauge outfit 1 contact; It is spherical that claw 5 lower ends are measured on a left side, and spherical helping contact with the hole inwall, a left side measure claw 5 pass on the gauge rod 3 strip hole by screw thread with show bar 4 and fixedly connected; Compression spring 8 is enclosed within a left side and measures on the gauge rod 3 of claw 5 right-hand members, and compression spring 8 left ends are stuck on the pin 9, and compression spring 8 right-hand members are stuck on gauge rod 3 inner steps; Sliding axle 7 places in gauge rod 3 right-hand members; Right to measure claw 6 lower ends be spherical, and the right claw 6 of measuring passes gauge rod 3 right-hand members and is connected on the gauge rod 3 by packing ring and fixed by nut behind the via hole on corresponding strip hole and the sliding axle 7 up and down.
During actual the use, left side measurement claw 5 and the right claw 6 of measuring are positioned at end-face hole during this gage measuring, and remainder is positioned at outside the hole, has solved the shallow endoporus of end face for existing restriction of measuring measurer self shape.Registration by dial gauge changes, and just can accurately measure the dimensional accuracy and the circularity of endoporus.
Measuring diameter of phi 360H6, dark 5, the hole of circularity 0.02 is the example explanation.Earlier dial gauge gauge outfit 1 is placed in fixed cover 2 terminations, and pass through screw retention, adjust the right claw 6 of measuring then, make it be in the range intermediateness, detect by outside micrometer, making the distance in the head outside, both sides is 360h5, and dial gauge gauge outfit 1 expression number is adjusted into 0, and this moment, this measurer reached the measurement state.During measurement two left sides are measured claws 5 and the right claw 6 of measuring contact with end face inner hole wall to be measured, note observing the registration variation of table, the hole dimension precision can be read at this moment; And then dial gauge gauge outfit 1 expression number is adjusted into 0, and guarantee both sides head contact hole wall, rotate the diverse location of this measurer in the hole, the registration of observing dial gauge gauge outfit 1 changes, and this moment, the hole circle degree can be read.Because of adopting a left side to measure claw 5 and right claw 6 inner blocking types of measuring, the structure that table bar 4 touches dial gauge gauge outfits 1 contact, the registration by dial gauge changes, thereby can accurately measure the dimensional accuracy and the circularity of endoporus.Thereby solved the shallow hole measuring poor accuracy of end face, precision is low, the measuring operation complicated problems has improved working (machining) efficiency, provides technical guarantee for producing high quality of products.This measurer in constant temperature subsidiary factory of Qiqihaer No.2 Machine Tool Factory making-up shop through using checking, this apparatus measures accurately and reliably, the precision height, measuring operation is easy.
