Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of speed pickup performance index detection device of the utility model, the speed pickup that many groups are different can be detected simultaneously, it specifically comprises: main spindle box 2, base 8, main shaft 3, gear 4 and sensor mounting unit, main spindle box 2 inside is empty and bottom-open, base 8 is connected to the unlimited place bottom main spindle box 2, surrounds a cavity together with main spindle box 2; Main shaft 3 is connected horizontally on main spindle box 2 by bearing, and the end of main shaft 3 is connected with motor 1, and motor 1 is arranged on main spindle box 2; Gear 4 is at least provided with two, and all gears 4 are all connected on main shaft 3, and sensor mounting unit also comprises multiple, and correspondingly with gear 4 arranges.Sensor mounting unit comprises: sensor holder 6, guide pole 7, threaded line pipe 9 and handle 10, and sensor holder 6 is arranged on the top of main spindle box 2, for installing sensor 5 to be measured; As Fig. 2, the top of main spindle box 2 has hole, and one end of sensor 5 to be measured penetrates in main spindle box 2, just to the flank of tooth of gear 4 by this hole; The two ends of each sensing seat are all fixedly connected with guide pole 7, and guide pole 7 passes vertically through main spindle box 2 and base 8, and are slidably connected with main spindle box 2 and base 8 respectively; The two ends of guide pole 7 are equipped with nut, and the nut of guide pole 7 lower end is positioned at the below of base 8, and and leave gap between base 8, facilitate guide pole 7 respect thereto 8 and main spindle box 2 to move up and down; On the guide pole 7 of sensor holder 6 one end, be socketed with threaded line pipe 9, threaded line pipe 9 and guide pole 7 are slidably connected, and are connected outside it by screw thread with sensor holder 6, the axis of screw thread and the dead in line of corresponding guide pole 7, the bottom of threaded line pipe 9 connects with the upper surface of main spindle box 2; The side horizontal of sensor holder 6 is provided with slotted hole, and one end of handle 10 passes outside sensor holder 6 by this slotted hole, and the other end of handle 10 is fixedly connected with threaded line pipe 9.The height of slotted hole is greater than the diameter of handle 10, makes handle 10 while horizontally rotating, and can do the motion of above-below direction in slotted hole.
Preferably, guide pole 7 is linear bearing guide pole, and the junction of itself and main spindle box 2 or base 8 is all provided with linear bearing.
Preferably, in the place that main spindle box 2 top connects with threaded line pipe 9, around guide pole 7, an annular test boss is set, when needing the sensor detecting a certain model, according to the sensor of needs when detecting and the minor increment of gear 4, by the height of Milling Process adjustment test boss, until meet installation requirement; That tests boss is arranged so that the utility model can detect multiple different model sensor device, and the scope of application is wider.
The principle of work of a kind of speed pickup of the utility model performance index detection device is as follows:
First, according to the diameter of corresponding gear 4, and handle 10 is gone to correct position, adjust the setting height(from bottom) of sensor 5 to be measured.Due to the Jun You edge, two ends of slotted hole, therefore handle 10 can only at certain angle range of motion, accordingly, threaded line pipe 9 also can only rotate in certain angular range, the rotating band dynamic sensor seat 6 relative main case 2 of threaded line pipe 9 moves up and down, and drives sensor 5 opposed gear 4 to be measured to move up and down; Namely the relative distance between sensor 5 to be measured and gear 4 is limited within the specific limits, and after sensor 5 to be measured is installed, namely the range of movement between itself and gear 4 is determined, there will not be the situation that sensor 5 to be measured collides with gear 4.Then, starter motor 1, allow gear 4 with the rotational speed of regulation, sensor 5 to be measured starts the kinematic parameter recording gear 4, can determine the performance of respective sensor according to the kinematic parameter detected, realizes the object of detection speed sensor.
When adjusting the distance between sensor 5 to be measured and gear 4, be rotated counterclockwise handle 10, threaded line pipe 9 rotates counterclockwise around guide pole 7, sensor holder 6 cannot rotate, suppose that screw thread is dextrorotation, under the effect of screw thread, sensor holder 6 drives guide pole 7 to move downward, and then drives sensor 5 to be measured to move near the direction of gear 4; When turn clockwise handle 10 time, sensor holder 6 drives sensor 5 to be measured to move to the direction away from gear 4, realizes the fine setting of sensor to be measured 5 and gear 4 spacing.That is, when handle 10 is positioned at the two ends of slotted hole, sensor 5 to be measured is positioned at distance gear 4 recently and farthest two positions just, as long as control two parameters well, sensor 5 to be measured and gear 4 just can be avoided to collide.
As can be seen from the above embodiments, the utility model is arranged on the mode on same main shaft 3 simultaneously by the multiple gear 4 of employing, and gives the configuration of each gear 4 correspondence a sensor, achieves the object simultaneously detecting different sensors, improves detection efficiency.Distance between sensor and gear 4 is adjusted by handle 10 and threaded line pipe 9, due to the Jun You edge, two ends of slotted hole, handle 10 and threaded line pipe 9 can only be rotated in certain angular range, and therefore the move distance of sensor 5 to be measured is controlled in certain limit; Sensor 5 to be measured can not collide with gear 4 after installing, and testing process can not stop because gear 4 damages, and detection time is short, efficiency is high.Linear bearing guide pole selected by guide pole 7, and is connected with main spindle box 2 and base 8 by linear bearing, and the two ends of each sensor holder 6 are all connected with linear bearing guide pole, and therefore sensor 5 to be measured can not deflect in motion process; And the motion of sensor holder 6 is promoted by screw thread, sensor holder 6 can the screw thread of moment and threaded line pipe 9 be close under gravity, and the Adjustment precision of sensor 5 move distance to be measured is high, and the sensor performance index detected is more accurate.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
