Abstract
The utility model relates to a motor locked -rotor test frock, including unable adjustment base, about being equipped with and being used for, the unable adjustment base top cooperates with fixed bottom plate and the top board of treating the pivot of experimental motor of centre gripping, the bottom plate along the assembly of upper and lower direction position adjustable on the bracing piece that extends along upper and lower direction, and be equipped with between bottom plate and the bracing piece and be used for after bottom plate shift adjusting targets in place the fixed bottom plate location structure of bottom plate, the bracing piece sets firmly unable adjustment base is last, is equipped with the backup pad above unable adjustment base, and upward be equipped with the axial in the backup pad and along the internal thread hole that upper and lower direction is extended, be equipped with the roof pressure lead screw in the internal thread hole soon, the top board sets firmly the lower extreme of roof pressure lead screw. Utilize top board and bottom plate to realize the stable fastening to motor shaft, assurance test effect. Because upper and lower direction position adjustable is followed to the bottom plate assembles on the bracing piece, can adjust the position of bottom plate like this according to motor shaft's actual height.
Description
Technical field
The utility model relates to a kind of motor rotation blockage test tool.
Background technology
Motor is when rotating speed is 0, and still namely output torque stall occurs, and the reason of stall is all generally mechanical or artificial.During motor rotation blockage, power factor is extremely low, and electric current during stall can reach the several times of rated current, the time slightly length will burn out motor.Therefore, need to carry out locked rotor test to motor.
At present, have and to carry out locked rotor test after adopting the object such as yoke, rope machine shaft binding to be killed, the mode of this artificial binding not only unsightly, and also easily occurs when carrying out locked rotor test loosening, and affects measurement result.Also have and be screwed into suspension ring at the end face of machine shaft, then penetrate stall rod, be stuck on testing table and carry out locked rotor test, but this locked rotor test method to there is testing efficiency low, install and remove all comparatively loaded down with trivial details problem.
Summary of the invention
The utility model provides a kind of clamping machine shaft to stablize, installs and removes motor rotation blockage test tool quickly and easily.
The technical scheme of motor rotation blockage test tool provided by the utility model is: a kind of motor rotation blockage test tool, comprise firm banking, the bottom plate for coordinating the rotating shaft gripping motor to be tested up and down and top board is provided with above firm banking, described bottom plate along the vertical direction position adjustable be assemblied on the support bar that extends along the vertical direction, and be provided with between bottom plate and support bar for move at bottom plate adjust to the right place after by bottom plate location structure fixing for bottom plate, support bar is installed on described firm banking, upper backup pad is provided with above firm banking, upper backup pad is provided with the internal thread hole axially extended along the vertical direction, top silk pressing bar is installed with in internal thread hole, described top board is installed in the lower end of described top silk pressing bar.
Described support bar is provided with external thread section, described bottom plate location structure is upper clamping nut on the external thread section of spinning on described support bar and lower clamping nut, two clamping nuts spaced apart in the both sides up and down of described bottom plate to coordinate clamping position bottom plate.
Described support bar is screw structure.
Described upper backup pad and described support bar are fixed and are assembled.
The top of described top silk pressing bar is provided with turning handle.
The beneficial effects of the utility model are: motor rotation blockage test tool provided by the utility model in use, machine shaft to be fixed is moved between bottom plate and top board, rotate top silk pressing bar, utilize the threaded engagement of top silk pressing bar and internal thread hole to order about top board to move down, thus machine shaft clamping is fixed between bottom plate and top board, realize the fixing stall to machine shaft.After having tested, rotate backward top silk pressing bar, can drive on top board and move, release machine shaft.Further, due to bottom plate along the vertical direction position adjustable be assemblied on support bar, the position of bottom plate can be adjusted like this according to the true altitude of machine shaft, effectively expand the range of application of locked rotor test frock.
Further, utilize clamping nut up and down to carry out clamping and positioning as subiculum class location structure to bottom plate, Set and Positioning adjustment is comparatively simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of motor rotation blockage test tool provided by the utility model.
Embodiment
As shown in Figure 1, a kind of embodiment of motor rotation blockage test tool, locked rotor test frock in this embodiment comprises firm banking 1, firm banking 1 is installed with parallel along the vertical direction two support bars 2 extended, the bottom plate 4 for coordinating the rotating shaft gripping motor to be tested up and down and top board 6 is provided with above firm banking 1, bottom plate 4 along the vertical direction position adjustable be assemblied on two support bars 2 that extend along the vertical direction, and be provided with between bottom plate 4 and support bar 2 for move at bottom plate 2 adjust to the right place after by bottom plate location structure fixing for bottom plate 2, two support bars in the present embodiment are screw structure, corresponding, bottom plate location structure is specially upper clamping nut 5 on the external thread section of spinning on support bar 2 and lower clamping nut 3, after by dynamic for bottom plate adjustment putting in place, utilize clamping nut corresponding matching up and down bottom plate can be fixed on support bar.
In the present embodiment, upper backup pad 8 is fixedly equipped with at the tip position place of two support bars, upper backup pad 8 is positioned at above firm banking 1, on upper backup pad 8, correspondence is provided with the internal thread hole axially extended along the vertical direction, in internal thread hole, be installed with top silk pressing bar 7, top board 6 is installed in the lower end of top silk pressing bar 7.And for the ease of operation, be provided with turning handle 10 at the top of top silk pressing bar.
During use, according to the position of machine shaft to be tested, the height of adjustment bottom plate 4, specifically clamp the position realization of nut up and down to being fixedly clamped after bottom plate adjustment by adjustment, be placed on after on bottom plate 4 at machine shaft, rotate top silk pressing bar 7, drive top board 6 to move down and clamp machine shaft to coordinate with bottom plate 4, ensure the validity of motor rotation blockage test.After test completes, rotate backward top silk pressing bar 7, drive on top board 6 and move, machine shaft can be removed from bottom plate 4.When motor rotation blockage test tool that the present embodiment provides uses, mounting or dismounting all more for convenience, and what utilize screw mandrel self locks the machine shaft that is fixedly clamped that performance guarantee can be comparatively stable, and then warranty test effect.
In above-described embodiment, support bar is screw structure, in other embodiments, also only can arrange external thread section at the bar fragment position place, local of support bar, can realize equally clamping nut gripping bottom plate up and down.Certainly, also other bottom plate location structure can be adopted to realize fixing bottom plate, as arranged spaced apart along the vertical direction multiple pin hole on support bar, simultaneously, bottom plate arranges single pin hole, when bottom plate is moved to appropriate location, fastening screw can be inserted in corresponding through pin hole to realize the location to bottom plate.The adjustment elongated hole extended along the vertical direction also can be set on support bar, bottom plate be arranged and the adjusting bolt regulating elongated hole guiding movement to coordinate, after bottom plate is moved up and down putting in place, utilize set nut to be locked by bottom plate and adjusting position.
