Description
Technical Field
The invention relates to the technical field of sensor device manufacturing, in particular to a contact signal generating device for detecting the in-place state of a conveying trolley.
Background
In a production line of an automobile manufacturing enterprise, a self-propelled trolley is generally adopted for conveying parts among processes, a travel switch is usually arranged at a key point in the production line, a roller handle extending outwards is arranged on one side of the travel switch, and a roller for contacting with a measured object is arranged at an extending end of the roller handle; when the self-propelled trolley works, the self-propelled trolley moves to contact with the roller and then outputs a contact signal to the controller so as to control the subsequent operation of the self-propelled trolley, however, the following problems exist in the practical use, (1) because the controller inevitably has time delay in reaction, the self-propelled trolley can crash a travel switch when vertically descending; (2) because the roller handle of the travel switch has only one-direction freedom degree, and the rest directions are rigid, when the hoisted self-propelled trolley in a swinging state is in contact with the roller, the roller handle can be bent and deformed by lateral force, so that the contact signal output by the travel switch is abnormal, and further the fault abnormal wire stop of the self-propelled trolley is caused.
Disclosure of Invention
The invention provides a contact signal generating device which can solve the problem that a self-propelled trolley is abnormally stopped due to the fact that a travel switch in an automobile part conveying line is easy to crash or deform and the output signal of the travel switch is abnormal.
In order to solve the problems, the technical scheme adopted by the invention is as follows: this contact signal generating device, including travel switch, one side of travel switch is equipped with the gyro wheel handle that outwards stretches out, the end that stretches out of gyro wheel handle is equipped with the gyro wheel, be equipped with the crimping board on the gyro wheel, it has the telescopic link to erect on the crimping board, the telescopic link is from last universal wheel base and the locating plate of down being equipped with in proper order, the universal wheel base with be equipped with the suit between the locating plate and be in spring on the telescopic link, be equipped with the universal wheel that is used for with the testee contact on the universal wheel base.
In the above technical solution, a more specific technical solution may also be: the telescopic rod comprises a fixed part and a telescopic part, the universal wheel base is arranged at the top end of the telescopic part, and the positioning plate is fixedly arranged at the joint of the telescopic part and the fixed part.
Further: one side of locating plate is equipped with the mounting panel, be equipped with the mounting hole on the mounting panel.
Further: the universal wheel is a universal bull's eye wheel.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
1. the universal wheel base is provided with a universal wheel which is used for contacting with a tested object; on one hand, the spring absorbs the impact force in the vertical direction, and the self-propelled trolley cannot be damaged when vertically descending; on the other hand, the universal wheel and the hoisted swinging self-propelled trolley generate 360-degree free rolling friction, so that the lateral force generated when the compression joint plate is in contact with the roller is eliminated, the normal contact signal of the travel switch is ensured, and the normal operation of the self-propelled trolley is further ensured.
2. Because one side of the positioning plate is provided with the mounting plate, the mounting plate is provided with the mounting hole; the device can be installed at key points in a production line, and the reliability of the device is enhanced.

Fig. 2 is a left side view of fig. 1.
Fig. 3 is a schematic perspective view of an embodiment of the present invention.
Detailed Description
The invention will be further described in detail with reference to the following examples:
the contact signal generating device shown in fig. 1, 2 and 3 comprises a travel switch 1, wherein one side of the travel switch 1 is provided with an outward extending roller handle 11, an extending end of the roller handle 11 is provided with a roller 12, the roller 12 is provided with a compression joint plate 2, a telescopic rod 3 is erected on the compression joint plate 2, and the telescopic rod 3 is sequentially provided with a universal wheel base 7 and a positioning plate 4 from top to bottom; the telescopic rod 3 comprises a fixed part 32 and a telescopic part 31, a universal wheel base 7 is fixed at the top end of the telescopic part 31, a positioning plate 4 is fixedly sleeved at the joint of the telescopic part 31 and the fixed part 32, a spring 6 arranged on the telescopic part 31 is arranged between the positioning plate 4 and the universal wheel base 7, a mounting plate 5 is arranged on one side of the positioning plate 4, and a mounting hole is formed in the mounting plate 5; the universal wheel base 7 is provided with a universal wheel 8 which is used for contacting with a measured object 9; the universal wheel 8 is a universal bull's eye wheel.
When the self-propelled trolley with the automobile parts is under the action of the electric chain type hoist crane, the self-propelled trolley descends to be in contact with the universal bull's eye wheels, the universal bull's eye wheels move downwards along with the universal bull's eye wheels until the compression joint plate touches the roller, the spring contracts the stress of the roller, and the travel switch outputs a contact signal to the controller to control the subsequent operation of the self-propelled trolley. On one hand, the spring absorbs the impact force in the vertical direction, and the self-propelled trolley cannot be damaged when vertically descending; on the other hand, the universal bull's eye wheel produces 360 degrees free rolling friction with the wobbling of hoist and mount by oneself the dolly, has eliminated the yawing force when crimping board and gyro wheel contact, has guaranteed travel switch contact signal's normal, and then has guaranteed the normal operating of by oneself the dolly.
