Abstract
The utility model discloses an awl fastening device for a cone-and-plate viscometer. The awl fastening device comprises a rotation shaft of a motor, an awl and a sleeve, wherein the awl and the sleeve are arranged above a slab; connecting rods of the rotation shaft and the awl are respectively inserted into two ends of the sleeve; a pair of upper threaded holes are symmetrically formed in a position, corresponding to the rotation shaft, on the upper part of the sleeve; a pair of lower threaded holes are symmetrically formed in a position, corresponding to the connecting rod of the awl, on the lower part of the sleeve; fastening screws are respectively arranged in the upper threaded holes and the lower threaded holes. The fastening screws are symmetrically arranged to fix the awl, and a stress and a torque on the rotation shaft from the fastening screws are mutually offset; when the viscosity is measured, the awl in high speed has good balance property, so that the oscillating range of the awl is effectively reduced and the measuring stability and accuracy of the viscometer are greatly improved.
Description
Technical field
The utility model relates to viscosity meter technical field, especially relates to a kind of cone-and-plate viscometer awl fastener.
Background technology
Cone-and-plate viscometer is the viscosity measurement experimental provision that Chemical Manufacture and research are often used, and the fastening means of its critical piece awl as shown in Figure 2.
Conventionally use the fixing awl 6 of single pin 8 and sleeve 3, the viscosity meter of this structure uses very general in Chemical Manufacture and research experiment.But, in actual measurement process, the awl of viscosity meter drives in High Rotation Speed state by the rotating shaft 2 of motor 1, singly lock and admittedly cause awl balance poor, along with constantly carrying out of experiment, the high-speed rotary change of team causes main measurement component-awl drifts about, flat board 7 central authorities under awl meeting substantial deviation, and the direct result producing is like this measurement data stability and the non-constant of reappearance.In addition, due to the dull and stereotyped central authorities of awl substantial deviation, in High Rotation Speed situation, can strengthen awl and the dull and stereotyped rate of wear, increase the load of viscosity meter main frame, on producing impact greatly the serviceable life of viscosity meter.
Utility model content
For prior art deficiency, technical problem to be solved in the utility model is to provide a kind of cone-and-plate viscometer awl fastener, and it reduces the amplitude that swings back and forth of awl.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cone-and-plate viscometer awl fastener, comprise the rotating shaft of motor and awl and the sleeve of dull and stereotyped top, the connecting link of described rotating shaft and awl inserts respectively the two ends of sleeve, the corresponding rotating shaft of described upper cartridge is arranged with a pair of top threaded hole, the connecting link of the corresponding awl of described lower cartridge is arranged with a pair of lower thread hole, in described top threaded hole and lower thread hole, is equipped with holding screw.
Further, described top threaded hole and lower thread hole measure-alike, coordinates top threaded hole identical with the Tightening moment of all holding screws in lower thread hole.
Described top threaded hole is located at sleeve 3/4 At The Height, and lower thread hole is located at sleeve 1/4 At The Height.
The utility model compared with prior art, have the following advantages: holding screw is symmetrical arranged fixing awl, the force and moment of answering that holding screw countershaft produces is cancelled out each other, in the time of viscosity measurement, the awl balance of high-speed rotation is good, effectively reduce the amplitude that swings back and forth of awl, significantly improved stability and accuracy that viscosity meter is measured, and extend the serviceable life of measuring equipment.
Brief description of the drawings
Below the mark in the each width accompanying drawing of this instructions expressed content and figure is briefly described:
Fig. 1 is the utility model awl fastener structural representation.
Fig. 2 is existing awl fastener structural representation.
In figure: 1. motor, 2. rotating shaft, 3. sleeve, 4. holding screw I, 41. holding screw II, 5. holding screw III, 51. holding screw IV, 6. awl, 7. flat board, 8. single pin.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, this cone-and-plate viscometer awl fastener, by sleeve 3 by reliable and stable the coupling together of awl 6 of the rotating shaft of motor 12 and dull and stereotyped 7 tops.
The connecting link of rotating shaft 2 and awl 6 inserts respectively in the two ends up and down of sleeve 3, the corresponding rotating shaft in sleeve 3 tops is arranged with a pair of top threaded hole, the connecting link of the corresponding awl in sleeve 3 bottoms is arranged with a pair of lower thread hole, in two top threaded holes, symmetry is combined with holding screw I 4 and holding screw II 41, and in two lower thread holes, symmetry is combined with holding screw III 5 and holding screw IV 51.
Top threaded hole is located at sleeve 3/4 At The Height, and lower thread hole is located at sleeve 1/4 At The Height, fixing good reliability.
Top threaded hole and lower thread hole measure-alike, and coordinate top threaded hole identical with the Tightening moment of all holding screws in lower thread hole; Top holding screw after fastening is symmetrical, and bottom holding screw is symmetrical, and holding screw is symmetrical arranged fixing awl, and the force and moment of answering that holding screw countershaft produces is cancelled out each other.
In the time of viscosity measurement, the awl balance of high-speed rotation is good, effectively reduces the amplitude that swings back and forth of awl, has significantly improved stability and accuracy that viscosity meter is measured.
Add man-hour, first process respectively tapped hole at 1/4 and 3/4 At The Height of sleeve, mark the symmetric position in these two holes along sleeve, in symmetric position, process equally two threaded holes that dimensions is identical; Then, with sleeve, rotating shaft and awl are coupled together.Cost of manufacture is low, improves effect good, has solved the technical barrier that is always perplexing testing crew.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
