Abstract
The utility model relates to a kind of hollow shaft encoder, a kind of clamped-in style hollow shaft encoder specifically, this displacement transducer comprises encoder main body, hollow spindle, bearing, code-disc, encoder basement, retaining ring, circuit board and shell, it is characterized in that: end locking place processing annular groove of described hollow spindle, the endoporus of described retaining ring is processed with an annular projection, and the bossing installation by adhering of the annular in described retaining ring is in the annular groove of hollow spindle.The utility model can be combined closely with machinery, simple and reasonable, and Installation and Debugging are convenient, and cost is low, and production efficiency is high, fault rate is low and long service life.
Description
Technical field
The utility model relates to a kind of hollow shaft encoder, specifically a kind of hollow shaft encoder enhancing degree of holding tightly.
Background technology
Along with the development of China's economy and the progress of science and technology, the requirement of people to scrambler is also more and more stricter.Along with hollow shaft encoder birth its existing become one of topmost high-acruracy survey product of industrial control field.Hollow shaft encoder is that photoelectricity and mechanical displacement sensor exquisiteness are structurally integrated, fully combine the advantage of photoelectric encoder and mechanical measurement, hollow shaft encoder is specially adapted to linear rail system, also be applicable to other multinomial fields simultaneously, such as: the relative dimensions such as hydraulic cylinder system, testing machine, press, papermaking equipment, textile machine, printing machinery, horizontal control instrument are measured and position control, the control of electro-hydraulic servo universal hydraulic testing machine, can substitute grating scale completely and use.
Its structure of heavy caliber hollow shaft encoder used in the market is with hollow spindle, retaining ring and a main body etc., its shortcoming is the deficiency due to self degree of holding tightly, cannot be combined closely with machinery, although measurement result can reach measurement requirement reluctantly, but its precision and resolution can produce larger deviation because of the deficiency of degree of holding tightly, and easily break down, installment and debugging is also inconvenient, inefficiency.
Summary of the invention
The purpose of this utility model will provide a kind of to strengthen degree of holding tightly, and can combine closely with machinery, simple and reasonable, Installation and Debugging are convenient, and cost is low, and production efficiency is high, fault rate is low and the hollow shaft encoder of long service life.
The purpose of this utility model realizes like this, this displacement transducer comprises encoder main body, hollow spindle, bearing, code-disc, encoder basement, retaining ring, circuit board and shell, it is characterized in that: end locking place processing annular groove of described hollow spindle, the endoporus of described retaining ring is processed with an annular projection, and the bossing installation by adhering of the annular in described retaining ring is in the annular groove of hollow spindle.
The utility model has the following advantages and good effect:
1, prior art hollow core main shaft end is provided with circular groove structure and back chipping process by the utility model, adopt partially embedded locking mode, effectively can strengthen the degree of holding tightly of hollow shaft encoder, strengthen the tight ness rating of hollow shaft encoder and mechanical part junction, facilitate hollow shaft encoder and the harmony of machinery, greatly reduce the deviate in measuring process thus improve the accuracy of measured value.
2, back chipping design of the present utility model, add elasticity and the intensity of hollow spindle, avoid scrambler hollow spindle when ultra-long time works and bend under the impact of external force and be out of shape, the tight ness rating of connection is more and more less, harmony phenomenon worse and worse.
3, the utility model structure is ingenious, reasonable in design, do not changing the elasticity and intensity that add hollow spindle under raw-material prerequisite, virtually save the input of the cost of raw material, decrease the maintenance frequency of user simultaneously and change number of times, decrease the artificial input of user, and then improve work efficiency.
4, the utility model not only slow down the generation causing the phenomenon be out of shape or bent when hollow shaft encoder main shaft works long hours under external force, and reduce the error of original hollow shaft encoder in precision, make measurement result more accurate, the cost that simultaneously also greatly reducing user drops into, manually drop into and the time drops into, and then improves work efficiency.
5, the utility model is at end locking place processing annular groove of main shaft, contribute to end locking place being arranged on hollow spindle that retaining ring is partially embedded, effectively can strengthen the degree of holding tightly of hollow shaft encoder, increase the tight ness rating that hollow shaft encoder contacts with mechanical part, the harmony of enhanced encoder and mechanical part.
Accompanying drawing explanation
Fig. 1 is clamped-in style hollow shaft encoder one-piece construction cut-open view.
Fig. 2 is the cut-open view of hollow spindle of the present utility model.
Fig. 3 is the cut-open view of retaining ring of the present utility model.
Embodiment
As shown in figure 1 and 2: this displacement transducer comprises encoder main body 1, hollow spindle 2, bearing 3, code-disc 4, encoder basement 5, retaining ring 6, circuit board 7 and shell 8, it is characterized in that: end locking place processing annular groove 9 of described hollow spindle 2, the endoporus of described retaining ring 6 is processed with an annular projection 10, and projection 10 installation by adhering of the annular in described retaining ring 6 is in the annular groove 9 of hollow spindle 2.
Design concept of the present utility model is different with existing hollow spindle scrambler, but using method is consistent.
