Abstract
The invention relates to a tooling for measuring a longer workpiece with a plurality of coaxial holes, especially for measuring the coaxiality of a hydraulic profile control injection pump body used for an oil field. The tooling is composed of a measuring rod and a positioning shaft. When the tooling is used, the positioning shaft is fixed on the body, and a dial indicator is used to measure the gaps between the orientations of the body and the measuring rod, so that the processing quality of the body can be detected. The tooling is simple in structure, is convenient to operate, can measure the coaxiality of the holes on the body simultaneously, guarantees the production and assembly accuracy of a device, and enables the subsequent rework probability and production cost of the device to be reduced and the quality of the device to be improved substantially.
Description
Technical field
The present invention relates to a kind of measurement and grow and have the frock of multiple coaxial aperture workpiece, be used in particular for the measurement of the hydraulic profile control injection pump body right alignment of using in oil field.
Background technology
The hydraulic profile control injection pump of applying in oil field oil water operation is at present fluid pressure drive device, the right alignment of the parts such as hydraulic cylinder, cylinder sleeve, piston is had relatively high expectations, because these parts are mounted on body, so the requirement on machining accuracy of body is higher, need to strictly control again.Do not reach accuracy requirement, each parts are easy to occur wearing and tearing, and then cause leakage of oil, leakage.So just to construction operation, make troubles, be unfavorable for the enforcement of water filling operation.When production equipment, the measurement of right alignment is the important step of precision control, the aid of in the past not measuring, and the manufacture of body and processing are difficult to meet the operation demand of equipment, make the significantly raising of device fabrication cost, and are difficult to guarantee the quality of product.Cause a large amount of economic losses, and badly influenced the market standing of this hydraulic profile control injection pump.
Summary of the invention
The object of the invention is to overcome above-mentioned present situation, provide a kind of measurement to grow and have the frock of multiple coaxial aperture workpiece.
The technical solution adopted for the present invention to solve the technical problems is: sounding rod and locating shaft, consist of, during use, locating shaft is fixed on body, can check out the crudy of body by dial gauge measurement each orientation of body to the gap of sounding rod.
Beneficial effect of the present invention: simple in structure, easy to operate, can measure the right alignment in each hole on body simultaneously, guarantee production and the assembly precision of equipment, reduce the follow-up probability of doing over again of equipment.Greatly improve equipment quality and reduced the production cost of equipment.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
1-sounding rod, 2-locating shaft in figure.
Embodiment
Below in conjunction with accompanying drawing to the detailed description of the invention:
As shown in the figure: this frock is comprised of sounding rod (1) and locating shaft (2).It is upper that locating shaft (2) is used screw thread to fix and be welded on sounding rod (1), and then one-time positioning turning processes, and has guaranteed the precision of whole frock.During measurement, locating shaft is fixed on the hole of body, each needs the hole all directions of controlling dimension to the gap of sounding rod (1) with dial gauge, to measure body, can calculate the machining precision in each hole of body, and it is convenient to measure, accurately.Sounding rod is accurately machined, and scale error is minimum, so can guarantee the precision of measurement size, in addition for handled easily, sounding rod is made into hollow, to alleviate the weight of frock.
Claims (2)
1. a frock for multiple coaxial aperture workpiece is grown and is had in measurement, sounding rod (1) and locating shaft (2), consists of.
2. as described in right 1, sounding rod inside is hollow.
