Description
Technical Field
The utility model relates to a stopper detection device, especially a stopper clearance on-line measuring device.
Background
The traditional brake clearance detection method is a feeler check or an optical device detection. Because the inside spring that is equipped with of stopper influences optical detection, and it is great to optical detection interference, needs to adopt more frock, but the degree of accuracy still is lower. The traditional feeler gauge is low in checking efficiency, low in precision and high in labor intensity.
SUMMERY OF THE UTILITY MODEL
The utility model provides a higher stopper clearance on-line measuring device of precision for solving the technical problem who exists among the well-known technique.
The utility model discloses a technical scheme who takes for solving the technical problem that exists among the well-known technique is: the utility model provides a stopper clearance on-line measuring device, includes the top board and the holding down plate and at least three split type digital display percentage table and the press that the level set up the top board with it has three at least detection biasing springs along circumference equipartition to press between the holding down plate, it adorns on the screw to detect biasing spring suit, the fix with screw is on the holding down plate, the top board suit is in on the screw be provided with the jack of three at least along circumference equipartition on the holding down plate, gu of probe rod one-to-one of split type digital display percentage table is adorned in the jack, the top board with the output of press is connected.
The utility model has the advantages and positive effects that: the press machine is adopted to drive the lower pressing plate to press the guide pillar, the digital display dial indicator connected to the lower pressing plate is adopted to detect the action distance of the brake armature, the action distance is used as the real-time data acquisition of the brake clearance, the detected data is the real working clearance of the brake, and the data is accurate and reliable. And the press machine is adopted for driving, so that the efficiency is high, and the labor intensity is low. The detection pressure spring is arranged between the upper pressure plate and the lower pressure plate, so that the lower pressure plate can be always in contact with all guide posts, and the measurement error caused by the unparallel upper surface and lower surface of the stator is avoided. Therefore the utility model discloses higher detection precision has.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a stator; 2. a spring; 3. an armature; 4. a rotor; 5. a guide post; 6. a lower pressing plate; 7. a split type digital display dial indicator; 8. detecting a pressure spring; 9. an upper pressure plate; 10. a screw; 11. a press machine.
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
referring to fig. 1, the online brake clearance detection device includes an upper press plate 9 and a lower press plate 6 which are horizontally arranged, at least three split digital display dial indicators 7 and a press machine 11, at least three detection pressure springs 8 which are uniformly distributed along the circumferential direction are clamped between the upper press plate 9 and the lower press plate 6, the detection pressure springs 8 are sleeved on screws 10, the screws 10 are fixed on the lower press plate 6, the upper press plate 9 is sleeved on the screws 10, at least three jacks which are uniformly distributed along the circumferential direction are arranged on the lower press plate 6, probe rods of the split digital display dial indicators 7 are fixedly arranged in the jacks in a one-to-one correspondence manner, and the upper press plate 9 is connected with an output end of the press machine 11.
During detection, a brake composed of a stator 1 with an annular coil and a spring 2, an armature 3, a rotor 4 and a guide post 5 is placed on a bottom plate of a press machine 11, and the rotor 4 and the guide post 5 face upwards. The output end of the press moves downwards, so that a lower pressing plate 6 of the detection device is pressed on a guide post 5, then a brake coil is electrified, an armature 3 is attracted to a stator 1 by the coil, when the armature is electrified, a probe rod of a dial indicator is pressed on the armature 3, then the dial indicator is controlled by a program to reset, then a power supply of the brake coil is cut off, and after the brake is powered off, the reading of the dial indicator, namely a gap value, is read. The actual working clearance of the brake is obtained by measuring the action distance of the armature of the brake to detect the clearance of the brake, and the data is accurate and reliable.
The value of the force applied by the pressing spring is detected to be larger than the sum of the spring pressures of the brake, so that the lower pressing plate 6 is always in contact with all the guide posts 5, and the measurement error caused by the fact that the upper surface and the lower surface of the stator are not parallel is eliminated. The length of a probe rod of the dial indicator is larger than the thickness of the rotor, so that the end part of the probe rod always presses the armature 3 when the armature of the brake acts.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is in the light of the following claims.
