Background technology
After the cartridge finished product machines, need detect its moment of torsion, with guarantee toner cartridge moment of torsion within specialized range, guarantee the quality of product, make driving member such as driven wheel or web member damage distortion easily if moment of torsion is excessive, influence the serviceable life of whole toner cartridge.The method of traditional measurement moment of torsion all is to adopt staff that torque tester is connected with the driving shaft of toner cartridge, then the hand rotation torque tester, draw the moment of torsion reading, but because the staff rotating speed is inhomogeneous, and angle is unfixing, and the torque value deviation of measuring is bigger.At present, the device that adopts mechanical system to measure has appearred in the industry, be that the utility model patent of CN201247386 discloses a kind of cartridge torque detecting apparatus as publication number, driving torque gauge by buncher rotates, cartridge is installed on the frock platform, the torque gauge other end is connected with cartridge, drives the cartridge rotation, thereby measures the moment of torsion of cartridge.Though measuring accuracy is more accurate, there is following problem in the prior art: 1, complex structure, and the engaged position area is big; 2, reading inconvenience, torque gauge is non-dismountable, and pointer can go to the torque gauge below; 3, adjust inconvenience, positioning tool is merely able to move up and down.
Summary of the invention
For addressing the above problem, it is a kind of simple in structure that the utility model provides, but the cartridge torque tester that easy to operate multidimensional is adjusted.
The utility model is that the technical scheme that its problem of solution adopts is:
But the cartridge torque tester that a kind of multidimensional is adjusted, comprise pedestal, the longitudinal direction of described pedestal is provided with the grip block that can clamp cartridge from both sides, described pedestal be provided with mount pad for the mounting torque instrument in a lateral direction, also be provided with the drive motor that rotates for the driving torque instrument on the described mount pad; But also be provided with the mount pad drive unit that the drive installation seat moves up and down on the described pedestal.
Preferably, described mount pad drive unit comprises the pole that is installed on the pedestal, and mount pad is slidingly mounted on the pole, and described mount pad drive unit also comprises mount pad is fixed on stationary installation on the pole.Further, described stationary installation comprises the crossbeam that is installed in the pole top, and screw thread is equipped with elevating lever on the described crossbeam, and the end of described elevating lever is connected with mount pad.
Preferably, described grip block one side is provided with the fixed head that is fixedly mounted on the pedestal, and the carriage release lever that can promote grip block is installed on the described fixed head.Further, described grip block is provided with the guide pole that slidably is installed on the fixed head.
Preferably, described mount pad is provided with mounting hole, and snap ring consistent with the torque gauge profile and that be connected with drive motor is installed in the described mounting hole.
The beneficial effects of the utility model are: simple in structure, easy to operate, the operator can pass through the grip block fixed carbon powder box of both sides, and can adjust cartridge position in a longitudinal direction; Then, the operator adjusts mount pad again and moves up and down, and the driving shaft of cartridge is docked with the end of probe of torque gauge, and last, the operator starts drive motor, and torque gauge is rotated, and torque gauge drives cartridge and rotates, and just can measure the torque value of cartridge.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is front elevation of the present utility model;
Fig. 2 is side view of the present utility model.
Embodiment
But the cartridge torque tester that a kind of multidimensional shown in accompanying drawing 1, accompanying drawing 2 is adjusted, comprise pedestal 1, the longitudinal direction of described pedestal 1 is provided with the grip block 2 that can clamp cartridge from both sides, one side of described grip block 2 is provided with the fixed head 3 that is fixedly mounted on the pedestal 1, the carriage release lever 4 that can promote grip block 2 is installed on the described fixed head 3, carriage release lever 4 spirals are installed on the fixed head 3, and its other end can freely rotate at its axial direction of grip block 2 upper edges.Grip block 2 is provided with the guide pole 8 that slidably is installed on the fixed head 3, and degree of accuracy and stability to guarantee that grip block 2 moves prevent that cartridge from arbitrarily rocking after being held.Certainly, the designer also can expect not adopting the structure of fixed head 3, carriage release lever 4 and guide pole 8, for example adopt the mode of sliding-rail sliding, also can make grip block 2 mobile at the longitudinal direction of pedestal 1, and then use location structure that grip block 2 is fixed on a certain position.
Described pedestal 1 be provided with mount pad 5 for mounting torque instrument 13 in a lateral direction, also be provided with the drive motor 6 that rotates for driving torque instrument 13 on the described mount pad 5, drive motor 6 can adopt stepper motor, be provided with control device in the described pedestal 1, be used for start and stop and the rotating speed of control drive motor 6.Grip block 2 and mount pad 5 can adopt mechanical system to move, but can make whole tester structure become more complicated, operability, degree of accuracy according to tester require to take all factors into consideration, adopted the mode of artificial adjustment namely enough, but adopt mechanical system to come driving torque instrument 13 to rotate, even to guarantee torque gauge 13 rotating speeds and dynamics.
Therefore, but pedestal 1 is provided with the mount pad drive unit that passes through manually to adjust that drive installation seat 5 moves up and down, described mount pad drive unit comprises the pole 7 that is installed on the pedestal 1, mount pad 5 is slidingly mounted on the pole 7, and described mount pad drive unit also comprises mount pad 5 is fixed on stationary installation on the pole 7.Described stationary installation comprises the crossbeam 9 that is installed in pole 7 tops, and screw thread is equipped with elevating lever 10 on the described crossbeam 9, and the end of described elevating lever 10 is connected with mount pad 5, and operator's rotation and lifting bar 10 is to a certain position, and mount pad 5 just rests on this position.Certainly, stationary installation can also adopt alternate manner, for example in the side of mount pad 5 screw is set, and when screw screws in mount pad 5, just mount pad 5 and pole 7 is fixed together.
Described mount pad 5 is provided with mounting hole 11, snap ring 12 consistent with torque gauge 13 profiles and that be connected with drive motor 6 is installed in the described mounting hole 11, the profile of general torque gauge 13 is polygon, snap ring 12 also is set to polygon, torque gauge 13 snaps in after the snap ring 12 like this, situation about can not skid with snap ring 12 just, both convenient the installation guarantees the degree of accuracy of measuring again.
Below in conjunction with accompanying drawing method of operating of the present utility model is further described, the operator is installed in torque gauge 13 in the mounting hole 11 earlier, then cartridge is placed between the grip block 2 of both sides, and driving shaft and the exerting oneself of torque gauge 13 of adjusting cartridge are held on same vertical plane, the operator tightens the carriage release lever 4 of both sides again, and cartridge can not moved.Next step, operator's rotation and lifting bar 10 moves up and down mount pad 5, the end of exerting oneself of adjusting torque gauge 13 overlaps fully with the driving shaft of cartridge, again with torque gauge 13 with on cartridge is connected.At last, the operator adjusts after the rotating speed of drive motor 6, just can start instrument, and draws the torque value of cartridge by the reading dial plate on the torque gauge 13.
Above instructions is described, only is principle of the present utility model and embodiment, everyly carries out any simple modification and variation according to essence of the present utility model, all belongs within the desired protection domain of the utility model.
