Specific embodiment
The attached drawing and specific example given below with reference to the utility model, is further described the utility model, it should be understood that this
A little embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model, the implementation based on the utility model
Example, those of ordinary skill in the art's every other embodiment obtained under the premise of no creative work.Belong to this
The protection scope of utility model.
A kind of special gauge measuring inner hole groove depth and circularity, including fixing sleeve 3, spring 1, dial gauge 7, bushing
8, handspike 4, cover board 10, positioning sleeve 12, Step Shaft 11, pin 13, spring 2 14, support arm 15, the support arm 15 and positioning sleeve
12 connections, the positioning sleeve 12 are connect with cover board 10, and the fixing sleeve 3 is connect with cover board 10, the fixing sleeve 3 and positioning sleeve 12
Connection, the Step Shaft 11 are slidably matched with positioning sleeve 12 and fixing sleeve 3 respectively, and the dial gauge 7 is by bushing 8 and fixes
3 connection of set, the bushing 8 are spirally connected with fixing sleeve 3 by screw 26, and 11 upper end of Step Shaft passes through spring 1 and bushing
8 offset, and have screw thread on the handspike 4 and Step Shaft 11, and handspike 4 passes through fixing sleeve 3 and matched with Step Shaft 11 by screw thread
It closes, the pin 13 is equipped with protrusion 131, and the pin 13 and spring 2 14 are each provided in support arm 15, are set on the support arm 15
There is through-hole, described 13 one end of pin passes through through-hole and is slidably matched with support arm 15, and one end and the support arm 15 of the spring 2 14 offset,
The other end offsets with protrusion 131, and the bottom of the Step Shaft 11 is equipped with trapezoidal groove, and 13 other end of pin is taper and position
It offsets in trapezoidal groove and with Step Shaft 11, the measurement end of the dial gauge 7 and the top of Step Shaft 11 offset；It is described fixed
Position set 12 is connect with cover board 10 specifically refers to removable connection, and the removable connection refers to further include screw 1, described fixed
Position set 12 is spirally connected by screw 1 with cover board 10；The bottom of the Step Shaft 11 is equipped with trapezoidal groove, and the trapezoidal groove is
Annular groove.
In the specific implementation, positioning sleeve 12 is fixed on cover board 10 with screw 1 in one end of workpiece 1 by the cooperation of cover board 10
On, it is furnished with Step Shaft 11 in positioning sleeve 12.When measurement starts, Step Shaft 11 is under the action of self weight and spring 1, in as schemed
Position shown in 1.Pin 13 in support arm 15 is always in contraction state under the screen resilience of spring 2 14, at this point, radius R1
< internal bore radius R makes it easily to pass in and out out of measured hole.
When measurement, a workpiece is first processed into qualified groove depth master body, the depth of slot will pass through accurate measurement, measure
Its standard value identifies on exemplar.The measurement of other workpiece groove depths uses comparative measurement method, with exemplar on this special gauge
It compares and obtains its groove depth angle value, to be determined.
When operation, groove depth master body is first checked and approved, drives 11 Step Shaft of piece number to move up by rotation handspike 4, Step Shaft
On the conical surface of trapezoidal groove push 13 pin of piece number mobile to exemplar outer diameter direction, until the slot bottom of workpiece, writes down dial gauge 7
Dial gauge zero-setting operation is given in the position of pointer.With same method, when measuring other workpiece, the position of percentage list index is observed
It sets, is compared with the position of master body, therefore, it is determined that whether it is qualified.
On several different locations of workpiece radial direction, inner hole groove depth is measured with same method, observes the reading of dial gauge
Situation of change, so that it may measure the circularity of slot bottom.
Step Shaft 11 is that the key part of the cubing is shown in Fig. 2, is cooperated with 12 high-precision gap of positioning sleeve, equipped with high-precision on axis
The conical surface for spending taper, when moving up Step Shaft manually, the conical surface pushes pin 13 to move radially to workpiece, until the slot of workpiece
Bottom.
The movement in moving process of pin 13 is excessive in order to prevent, and being detached from the conical surface should be designed to so that measurement result is invalid
L1 > L (L=R-R1) in figure.
Meanwhile axial movement distance for the ease of the Step Shaft that converts and pin move radially along workpiece the relationship of distance,
The taper angle θ of the conical surface should be designed as 45 ° of special angle (i.e. θ=1 tan) or θ=0.5 tan.When θ=45 °, radial distance and axis
To distance at 1: 1 relationship, convert very simple；When θ is designed as tan θ=0.5, radial distance and axial distance are at 1: 2
Conversion relation corresponds to the half of the percentage meter reading of axial distance, be converted into the moving distance (depth of slot) of pin.
The utility model and embodiments thereof are described above, description is not limiting, shown in the drawings
It also is one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field it is general
Logical technical staff is enlightened by it, without deviating from the purpose of the present invention, is not inventively designed and is somebody's turn to do
The similar frame mode of technical solution and embodiment, all should belong to the protection range of the utility model.
