Description
Technical field
The utility model belongs to diameter measuring device, relates to a kind of cylindrical shell bore diameter on-line measuring device, be specially adapted to cylindrical shell series products when adopting boring cutter bar bore hole, boring cutter bar need not exit cylinder bore and use while carrying out inner diameter measurement.
Background technology
Metal product work in-process, the high cylindrical shell series products of some internal diameter size accuracy requirements is when adopting boring cutter bar bore hole, and boring cutter bar is inconvenient to exit, and traditional micrometer inside caliper or dial bore gage cannot be implemented to measure.Will obtain accurately measured value, need adopt the advanced measuring equipment of portable three-coordinate measuring machine or laser tracker class to detect, the product having on the one hand there is no need to adopt this class advanced person's checkout equipment, and equipment investment is large, testing cost is high, uneconomical; On the other hand, equipment is subject to environmental restraint, and inconvenience is positioned over lathe side by valuable checkout equipment, waits each time and detects, and detects inconvenient operation.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, and a kind of cylindrical shell bore diameter on-line measuring device simple in structure, easy to use is provided.
Content of the present utility model is: a kind of cylindrical shell bore diameter on-line measuring device, it is characterized in that: by arc body (2), the internal diameter micrometer head (1) being connected with arc body (2) one end, and the measuring head (3) being connected with arc body (2) other end forms; Described internal diameter micrometer head (1) is located along the same line with the longitudinal center line of measuring head (3).
In content of the present utility model: described arc body (2) be shaped as falcate, circular arc or other arc.
In content of the present utility model: described internal diameter micrometer head (1) is the internal diameter micrometer head of micrometer inside caliper, and described measuring head (3) is the measuring head of micrometer inside caliper, described internal diameter micrometer head (1) and measuring head (3) all can adopt market to sell qualified < < micrometer inside caliper > > finished product accessory, for example: in the < < micrometer inside caliper > > product that the model of taking from the production of Chengdu amount cutlery incorporated company is SM306, also can adopt measurement range at other < < micrometer inside caliper > of 50-600mm > product accessories, to improve accuracy of measurement.Maximum length between described internal diameter micrometer head 1 and measuring head 3 is less than test product internal diameter;
In content of the present utility model: the material of described arc body (2) is preferably employing tool steel, can greatly reduce this device stress release distortion and cause measuring system error.
Compared with prior art, the utlity model has following feature and beneficial effect:
(1) adopt the utility model, measuring accuracy can be increased to the scale division value of micrometer head, measure accurately, thus effective control for product quality;

Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
Embodiment 1: referring to each accompanying drawing.
A cylindrical shell bore diameter on-line measuring device, by arc body 2, is connected the internal diameter micrometer head 1 of (being threaded) with arc body 2 one end, and measuring head 3 compositions that are connected (being threaded) with arc body 2 other ends; Described internal diameter micrometer head 1 is located along the same line with the longitudinal center line of measuring head 3; Described arc body 2 be shaped as falcate; Maximum length between described internal diameter micrometer head 1 and measuring head 3 is less than test product internal diameter;
The internal diameter micrometer head that described internal diameter micrometer head 1 is micrometer inside caliper, described measuring head 3 is measuring heads of micrometer inside caliper, described internal diameter micrometer head 1 and measuring head 3 all adopt market to sell qualified < < micrometer inside caliper > > finished product accessory, in the < < micrometer inside caliper > > product that the model of taking from the production of Chengdu amount cutlery incorporated company is SM306, (also can adopt measurement range at other < < micrometer inside caliper > of 50-600mm > product accessories, to improve accuracy of measurement),
The material of described arc body 2 adopts tool steel, can greatly reduce this device stress release distortion and cause measuring system error.
During use, internal diameter micrometer head 1 is connected to (screwing) with measuring head 3 with arc body 2, the outside micrometer matching by specification carries out school zero or definite reference zero to this device; Then be positioned over test product 4 endoporus, rotary inside diameter micrometer head 1, finds maximum position, axial direction to find minimum position in the radial direction of test product 4, takes reading, compare with the reference zero that starts check and correction, draw measured diameter (internal diameter) value of test product 4.
The utility model is not limited to above-described embodiment, all can implement and have described good result described in the utility model content.
