Abstract

The utility model relates to a dial gauge for mandrels. Both the dial gauge and an ejector pin are mounted on an upper beam and a lower beam of a frame, and the upper beam is parallel to the lower beam. The dial gauge for mandrels is characterized in that (1), the frame is fixedly mounted with one end of the upper beam, and is mounted with one end of the lower beam in a threaded meshing manner, and a frame nut is mounted on the frame below the lower beam in a meshing manner; (2), an ejector pin is mounted at the other end of the lower beam in a meshing manner, the upper portion of the ejector pin is designed into a pointed cone shape, and an ejector pin nut is mounted on the ejector pin above the end of the lower beam in a meshing manner; (3), the other end of the upper beam is made into a forked rack, the dial gauge is mounted on the upper portion of the forked rack and is locked by a locking nut, an adjusting pin is sleeved on the lower portion of the forked rack and coaxial with a measuring pointer of the dial gauge, and the lower portion of the adjusting pin is made into a pointed cone shape. The dial gauge for mandrels is simple in structure integrally, convenient in use, easy to manufacture, low in cost, and capable of guaranteeing processing quality of the mandrels.

Description

A kind of plug dial gauge
Technical field
The utility model belongs to fields of measurement, relates to dial gauge, especially a kind of plug dial gauge.
Background technology
Plug belongs to long axis workpiece, and length is longer, and diameter is bigger, and works under the most evil bad condition of high temperature, high pressure, and is therefore very high to the requirement on machining accuracy of plug.Especially carry out the car bowlder at plug, will adopt dial gauge to detect the diameter of axle and the right alignment of plug at any time,, guarantee the quality of weldless steel tube by this to guarantee the crudy of plug.Yet, existing dial gauge, its scope of measuring diameter is less, can't 20 centimetres of application diameters and even above plug, the diameter of axle of plug can't be guaranteed.
Summary of the invention
The purpose of this utility model is to provide a kind of plug dial gauge, and this dial gauge is suitable for diameter of mandrel, and easy to use, with low cost.
The purpose of this utility model is achieved in that
A kind of plug dial gauge comprises dial gauge, thimble, and the chaining pin of dial gauge and the coaxial setting of thimble, dial gauge and thimble are installed on the entablature and sill that a framework installs, and entablature and sill be arranged in parallel, it is characterized in that:
(1) framework and entablature one end install, and adopt the screw-threaded engagement mode to install with sill one end, and a framework nut are installed in engagement on the framework below the sill;
(2) thimble is installed in the engagement of the other end of sill, and this thimble top is made cone-shaped, and a thimble nut is installed in engagement on the thimble above the sill end;
(3) make forked at the other end of entablature, on forked top dial gauge is installed, this dial gauge is locked by trip bolt; At chaining pin coaxial package one adjusting pin of forked bottom and dial gauge, this adjusting pin bottom is made cone-shaped.
And described dial gauge is by trip bolt and forked 's top locking.
Advantage of the present utility model and good effect are:
1, this dial gauge adopts special framework, at the frame openings upper and lower side dial gauge and thimble is installed respectively.Because therefore the frame openings range finding much larger than the detection range finding of existing dial gauge, is applicable to that the diameter of axle of plug detects.
2, the sill of this dial gauge is adjustable, and thimble is also adjustable, so the application diameter scope is wider, also is applicable to the measurement right alignment simultaneously.
3, this dial gauge one-piece construction is simple, and is easy to use, makes easily, with low cost, can effectively guarantee the crudy of plug.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described; Need to prove: present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of plug dial gauge comprises dial gauge 4, thimble 11, and the chaining pin 6 of dial gauge and the coaxial setting of thimble, dial gauge and thimble are installed on the entablature 2 and sill 12 that a framework 1 installed, and entablature and sill be arranged in parallel.
Innovative point of the present utility model is:
(1) framework and entablature one end install, and adopt the screw-threaded engagement mode to install with sill one end, and a framework nut 13 are installed in engagement on the framework below the sill.
(2) thimble is installed in the engagement of the other end of sill, and this thimble top 9 is made cone-shaped, so that measure; A thimble nut 10 is installed in engagement on the thimble above the sill end.
(3) make forked 3 at the other end of entablature, on forked top dial gauge is installed, this dial gauge is locked by trip bolt 5; At chaining pin coaxial package one adjusting pin 7 of forked bottom and dial gauge, this adjusting pin bottom 8 is made cone-shaped.
Using method of the present utility model is:
(1) adjusts the position of sill according to the diameter range of plug by screw-threaded engagement, then with framework nut lock location;
(2) adjust the spacing of thimble top and adjusting pin bottom according to the diameter range of plug, and make it equal substantially, then with the locking of thimble nut.
(3) the framework frame is advanced plug, measure being installed on the diameter of mandrel between thimble top and the adjusting pin bottom then, push chaining pin by adjusting pin, thimble control dial gauge mode is measured the diameter precision of plug, also can measure the right alignment of plug.

Claims (2)

1. a plug dial gauge comprises dial gauge, thimble, and the chaining pin of dial gauge and the coaxial setting of thimble, dial gauge and thimble are installed on the entablature and sill that a framework installs, and entablature and sill be arranged in parallel, it is characterized in that:
(1) framework and entablature one end install, and adopt the screw-threaded engagement mode to install with sill one end, and a framework nut are installed in engagement on the framework below the sill;
(2) thimble is installed in the engagement of the other end of sill, and this thimble top is made cone-shaped, and a thimble nut is installed in engagement on the thimble above the sill end;
