Abstract
The utility model relates to a cam gear for button life test, including bottom plate, the actuating mechanism of setting in the bottom plate top, actuating mechanism includes motor, receives motor drive's drive gear, connects drive gear and drive gear's drive belt, the cam of being connected with drive gear, with cam articulated connecting plate, with connecting plate fixed connection's driving plate, set up a plurality of connecting rods in the driving plate below, this a cam gear for button life test can realize long-time reciprocal operation of pressing, and presses the precision of hitting higher.
Description
Technical Field
The utility model relates to an automation equipment field, in particular to a cam gear for button life-span test.
Background
Durability life test detection is required for various switches, buttons and related types of electronic products, but the existing detection mode is semi-manual detection, namely, a worker holds detection equipment for detection, so that time and labor are consumed, and efficiency is low.
Therefore, it is necessary to provide a new cam driving device for key life test to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cam gear for button life-span test can realize long-time reciprocal operation of pressing, and presses and hit the precision higher.
The utility model provides a technical scheme that its technical problem adopted is: a cam transmission device for testing the service life of a key comprises a bottom plate and a driving mechanism arranged above the bottom plate; the driving mechanism comprises a motor, a driving gear driven by the motor, a transmission gear, a transmission belt connected with the driving gear and the transmission gear, a cam connected with the transmission gear, a connecting plate hinged with the cam, a transmission plate fixedly connected with the connecting plate, and a plurality of connecting rods arranged below the transmission plate.
Specifically, the diameter of the driving gear is smaller than that of the transmission gear.
The utility model relates to a cam gear for button life-span test's beneficial effect is, can realize long-time reciprocal operation of hitting according to hitting, and press and hit the precision higher.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram for testing the life of a key of the present invention;
in the figure: 10. the automatic feeding device comprises a base plate, 11. a motor, 12. a driving gear, 13. a transmission gear, 14. a transmission belt, 15. a cam, 16. a connecting plate, 17. a placing plate, 18. a transmission plate and 19. a connecting rod.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, a cam gear for testing the life of a key comprises a cam gear for testing the life of a key, which comprises a bottom plate 10, a driving mechanism arranged above the bottom plate 10; the driving mechanism comprises a motor 11, a driving gear 12 driven by the motor 11, a transmission gear 13, a transmission belt 14 connected with the driving gear 12 and the transmission gear 13, a cam 15 connected with the transmission gear 13, a connecting plate 16 hinged with the cam 15, a transmission plate 18 fixedly connected with the connecting plate 16, and a plurality of connecting rods 19 arranged below the transmission plate 18.
Specifically, the diameter of the driving gear 12 is smaller than that of the transmission gear 13. The driving gear 12 having a smaller diameter than the transmission gear 13 can raise the transmission ratio so that the transmission force of the transmission gear 13 is greater.
The working principle of the cam transmission device for testing the service life of the key is as follows: the driving mechanism works, the motor 11 drives the driving gear 12 to rotate, the transmission gear 13 is driven to rotate through the transmission belt 14, the cam 15 is driven to rotate, the connecting plate 16 is driven to move up and down, and the connecting rod 19 can reciprocate up and down through the transmission plate 18.
Compared with the prior art, the cam transmission device for testing the service life of the key can realize long-time reciprocating pressing operation and has higher pressing precision.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
Claims (2)
1. A cam transmission device for testing the service life of a key is characterized by comprising a bottom plate and a driving mechanism arranged above the bottom plate;
