Abstract
The utility model discloses a limit switch button service life detection device which comprises a rectangular test bench and upright columns fixed at four corners of the test bench through nuts. One end of the bottom of the detection bench is fixedly connected with a motor. The test bench above the motor is provided with a through hole. A cam is arranged at the top of the test bench corresponding to the motor. The cam is connected with a rotating shaft of the motor. According to the device, rotating cam is employed to directly drive a limit switch button to carry out reciprocating motion, the adding of other auxiliary parts is avoided, and while detection requirements are satisfied, the cost is reduced. Rolling connection is employed to substitute traditional sliding connection, the resistance in the process of movement is effectively reduced, and the service life of each part is raised. At the same time, due to the rolling of the cam, the return of the limit switch button only depends on the elasticity of the button, thus a rebounding mechanism of the limit switch button is detected, and the detection accuracy and the reliability are raised further.
Description
Technical field
The utility model relates to a kind of limit switch button life detecting device, belongs to product checkout equipment in serviceable life technical field.
Background technology
At present, the elastic switch button has been widely applied in various products and the field, and the elastic switch button all relates to the detection in serviceable life in its quality testing process, to guarantee its quality.The general mode that comes and goes bump that adopts of traditional pick-up unit is tested, after being fixed on the elastic switch button on the worktable, carry out impact test according to the numerical value of setting, when reaching this numerical value, stop bump, whether the machinery and the function that detect the elastic switch button lost efficacy.
Chinese patent ZL200720056248.5 discloses a kind of finished product machine shift knob life test machine, it comprises a worktable, in worktable one bottom portion a motor is installed, worktable is provided with rotor wheel, rotor wheel is connected with machine shaft, rotor wheel was provided with the guide groove in axle center, described guide groove off-centre is connected with a connecting rod, the other end that connects is connecting push rod, the other end of push rod is connecting by tactile part, is useful on the anchor clamps of clamping test workpiece relatively by the place ahead of touching part at the other end of worktable.This scheme namely be adopt push rod by set numerical value repeatedly the impact switch button detect its serviceable life, owing to adopt the connecting rod knock shift knob, damage is caused on its top easily, and push rod is by the pulling of the guide groove on the rotor wheel during away from button, rather than reply the accurate bounce-back mechanism of detector switch button operate as normal whether by the bounce-back mechanism of shift knob self; Simultaneously, these testing machine parts are more, are fitted to each other and have relatively high expectations, and namely manufacturing accuracy requires high and causes cost to raise.
The utility model content
The purpose of this utility model is: a kind of limit switch button life detecting device is provided, with solve the accuracy of detection that traditional pick-up unit exists low, easily shift knob is caused damage, part is more, manufacturing cost is high problem.
The technical solution of the utility model:
A kind of limit switch button life detecting device, comprise the monitor station of rectangle, be fixed on the column of four corners of monitor station through nut, wherein: described monitor station bottom one end is connected with motor, the monitor station of motor top offers through hole, monitor station top and motor relevant position are furnished with a cam, and cam is connected with the rotating shaft of described motor.
The other end relative with described motor offers the mounting hole of some array arrangements on the described monitor station.
Described mounting hole is waist-shaped hole.
Described mounting hole has two at least.
Described mounting hole is used for fixing detected limit switch.
The beneficial effects of the utility model are: compared with prior art, the limit switch button life detecting device that the utility model provides, adopt the cam that rotates directly to drive the elastic switch button and carry out back and forth movement, removed the adding of other auxiliary components from and used, satisfied to detect and reduced cost when requiring; And adopting rolls connects traditional being slidingly connected of replacement, effectively reduces the resistance in the motion process, improves the serviceable life of each part; Simultaneously, because the rolling of cam makes the answer of limit switch button only rely on self elastic force, thereby make the elastic mechanism of limit switch button obtain detecting, further promoted accuracy of detection and reliability; In sum, this apparatus structure is simple, with low cost, accuracy of detection is high, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use view of the present utility model;
Among the figure: 1-monitor station, 2-column, 3-nut, 4-motor, 5-mounting hole, 6-cam, 7-limit switch, 8-button head.
Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described further, but that desired protection domain is not limited to is described;
As shown in Figure 1, the limit switch button life detecting device that the utility model provides, comprise the monitor station 1 of rectangle, be fixed on the column 2 of 1 four corners of monitor station through nut 3, wherein: described monitor station 1 bottom one end is connected with motor 4, the monitor station 1 of motor 4 tops offers through hole, monitor station 1 top and motor 4 relevant positions are furnished with a cam 6, and cam 6 is connected with the rotating shaft of described motor 4.
The other end relative with described motor 4 offers the mounting hole 5 of some array arrangements on the described monitor station 1; Install and fix detected elastic switch button by this mounting hole 5, make its testing process accurately stable.
Described mounting hole 5 is waist-shaped hole; The elastic switch button of the corresponding different model size of its energy has effectively promoted the scope of application of the present utility model.
Described mounting hole 5 has two at least.
Described mounting hole is used for fixing detected limit switch.
Embodiment: as shown in Figure 2, limit switch 7 is placed on the monitor station 1, by screw limit switch 7 is fixed on the mounting hole 5, the distance between test button 8 and the cam 6, and adjust at any time, making fits between button head 8 and the cam 6 gets final product; Starter motor 4, drive cam 6 rotations along with the work of motor 4, in the rotary course, the end that radius is bigger moves to button head 8, and the roller of button head 8 ends rotates thereupon, and then promote button head 8 to limit switch 7 interior motions, cam 6 continues rotation, after the bigger end of its radius is crossed button head 8, under the rebound effect of button head 8 self, make button head 8 reply normal condition, namely the roller of button head 8 ends is fitted with cam 6 constantly; Cam 6 rotates a circle namely to finish and once presses and reply, and the rotating speed of motor 4 is certain, can finish the detection to the serviceable life of limit switch button in setting-up time.
