Description
Technical field:
This utility model relates to internal thread depth measuring technical field, is specifically related to a kind of adjustable female thread
Depth measurement device.
Background technology:
Along with commercial production development at home, the impact of workpiece quality is played more and more important by screw thread process
Role, for the female thread processed, be difficult to directly measure the degree of depth arriving it, some measurement measurers are pin
The screwed hole of a kind of model size is designed.The degree of depth mostly shot by screw tap at present is to speculate the female thread of processing
The degree of depth, operation complexity directly perceived for the internal thread hole depth survey of different-diameter and pitch, cause measuring
Precision is relatively low, measures inefficiency.
Through retrieval, as Chinese patent internal thread depth measuring device (Authorization Notice No. is CN104567612A) is public
Drive a kind of internal thread depth measuring device, this internal thread depth measuring device be by with surveyed minor diameter of internal thread and spiral shell
On identical screw tap, mark groove reach the purpose that fathoms, it is impossible to realize a measurement apparatus and detect not
Measurement with internal diameter difference pitch depth of internal thread.This utility model is by changing measurement head and the work of different pitch
Stretching of dynamic gauge head, can realize different inner diameters and the measurement of the depth of internal thread of different pitch, reading mode class
Like vernier depth gauge, simple to operate, convenient reading.
Summary of the invention:
This utility model solves the scheme that its technical problem used: as it is shown in figure 1, a kind of adjustable in
Screw thread deepth measuring device, including main scale, vernier, frame anvil, movable gauge head, test probe replaceable, spring, described
Main scale lower end be fixedly connected with frame anvil, frame anvil one end is fixedly connected with test probe replaceable, frame anvil other end inner chamber set
Having movable gauge head, movable gauge head can slide at frame anvil inner chamber, described vernier set invests on main scale, can be along chi
Sliding in body length direction, described main scale is carved with the groove in units of millimeter.
Described frame anvil inner chamber is equipped with a spring, and one end of spring is fixedly installed on frame anvil inner chamber end face, another
End withstands on movable gauge head end face, and described spring remains compressive state, it is ensured that movable gauge head is in bullet all the time
Do well.
Described test probe replaceable has and the screw thread of tested female thread identical pitch, has the complete interchangeable of different pitch
Gauge head.
This utility model passes through technique scheme, there is the effect that the adjustable female thread of described one
Depth measurement device, by changing different length and the test probe replaceable of pitch, regulation activity gauge head stroke, can
To measure different inner diameters, the screwed hole degree of depth of different pitch, its simple in construction, it is simple to use.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Shown in figure: 1-main scale；2-vernier；3-frame anvil；4-activity gauge head；5-test probe replaceable；6-spring.
Detailed description of the invention
It is described in further detail below in conjunction with the most preferred embodiment shown in accompanying drawing: as it is shown in figure 1, a kind of adjustable
Internal thread depth measuring device, including main scale 1, vernier 2, frame anvil 3, movable gauge head 4, test probe replaceable 5,
Spring 6, described main scale 1 lower end is fixedly connected with frame anvil 3, and frame anvil 3 one end is fixedly connected with test probe replaceable
5, frame anvil 3 other end inner chamber is cased with movable gauge head 4, and movable gauge head 4 can slide at frame anvil 3 inner chamber, institute
Vernier 2 set stated invests on main scale 1, can slide along blade length direction, and described main scale 1 is carved with millimeter
Groove for unit.
Described frame anvil 3 inner chamber is equipped with a spring 6, and one end of spring 6 is fixedly installed in frame anvil 3 inner chamber end face
On, the other end withstands on movable gauge head 4 end face, and described spring 6 remains compressive state, it is ensured that movable survey
4 are in ejection state all the time.
Described test probe replaceable 5 has and the screw thread of tested female thread identical pitch, the choosing when measuring depth of internal thread
With the test probe replaceable 5 identical with female thread pitch, rotate main scale 1 and test probe replaceable 5 and movable gauge head 4 are screwed in
In tested screw thread, screw in screw thread lowermost end, coordinate registration, reading mode by main scale blade 1 and vernier 2
It is same as slide gauge.
Due to the utilization of technique scheme, this utility model compared with prior art has following advantages
The adjustable device of measuring internal thread of this utility model scheme, with complete test probe replaceable, by combination
The test probe replaceable of different pitch, can detect the depth of internal thread reaching different pitch；Movable gauge head is in compression spring
Effect is lower ejects frame anvil inner chamber, can detect, to contract, the depth of internal thread reaching different bottom diameters,
Reading mode is same as slide gauge, and operating process is simple, improves the efficiency and accuracy measured.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any
Limit.The technical scheme that all employings convert on an equal basis or equivalence is replaced and formed, all falls within this utility model right
Within protection domain.
