Description

A station detection device for an automobile production line

technical field

The utility model relates to a detection device, in particular to a detection device for a station in an automobile production line.

Background technique

In the automobile welding process, the general body welding main line has 11 stations. When the main line is fully loaded, there are 10 car bodies, and the car bodies are transported to the next station synchronously. Different stations have different Process requirements, for example, some stations are robot automatic welding; some stations are welding roof; Therefore, in the increasingly automated production line, whether there is a car body at the station needs to be automatically sensed, and the sensed signal is transmitted to the electronic control system, and the electronic control system transmits the signal to the equipment of each station. Execute the order, that is, if there is a car, it will be executed according to the process requirements; if there is no car, it will be executed according to waiting. Therefore, the application of the automobile station detection device in the body production line is more and more extensive.

In the prior art, the automobile station detection devices are divided into two types, one is contact type, and the other is non-contact type. The non-contact type generally detects whether there is a car on the production line station by means of light, electricity, and magnetism. However, due to the influence of foreign objects such as welding slag and flying dust, the light, electricity, and magnetic sensors are prone to sensor failure or reduced sensitivity. The price is higher than the contact detection device, so the general production line uses the contact detection device.

The contact detection device includes a detection switch, a sensor and a return component. The return component is directly connected to the sensor, and the sensor is fixed on the support separately. Once the position is determined, the position cannot be adjusted, and the application range is narrow. The returning part has low strength, and after repeated use, it is easy to fail and difficult to replace.

Contents of the invention

A station detection device for an automobile production line, comprising a travel switch and a fixed plate for fixing the travel switch, a sleeve is fixed on the top of the fixed plate, a push rod is arranged inside the sleeve, and a spring is covered on the push rod; The lower end of the above-mentioned spring is in contact with the boss at the lower part of the sleeve, and the upper end is in contact with the boss at the upper end of the ejector rod; the lower end of the ejector rod passes through the sleeve, and a collision block is fixed at the end, and the ejector rod drives the collision block to control the reciprocating motion. The opening and closing of the travel switch.

There is a connection plate on the sleeve, one side of the connection plate is fixed with the fixed plate, and the other side is fixed with the sleeve. The connection plate can be fixedly connected with the sleeve and the fixed plate by welding, so that the ejector rod can work more smoothly.

The connection plate and the travel switch are fixed on one side of an adjustment plate, and the other side of the adjustment plate is fixed to the fixed plate; there are positioning holes on the fixed plate; there are strip holes opposite to the positioning holes on the adjustment plate, and the positioning holes There is an adjusting bolt between the strip hole and the position of the adjusting plate can be adjusted according to the actual needs, and the adjusting plate and the fixing plate can be fixed with the adjusting bolt to make the ejector rod work normally.

The lower end of the ejector rod is connected with a fixing nut, and the end is fixed with the striker through threads. The lower end of the ejector rod can also be welded and fixed with the striker, which can make the striker and the ejector more tightly.

There are several fixing holes perpendicular to the inner hole of the collision block on the collision block. The inner hole of the collision block can be a vertical hole with a smooth inner wall, or a threaded hole, and the screw matching the fixing hole can pass through the fixing hole The impact block and the ejector rod can be fixed more firmly by being offset against the ejector rod.

The position detection device of the automobile production line described in the utility model, by setting a spring and a push rod in the sleeve, pressing down the push rod makes the push rod collide with the travel switch, and the travel switch transmits the signal to the electric control system, the structure is simple and the cost is low. Low, high measurement accuracy, strong durability, easy maintenance and replacement, long service life, wide application range.

Detailed ways

As shown in Figures 1 and 2, a station detection device for an automobile production line includes a travel switch 1 and a fixed plate 2 for fixing the travel switch 1. A vertical sleeve 6 is fixed on the upper part of the fixed plate 2, and a vertical sleeve 6 is fixed inside the sleeve 6. There is a push rod 4, and a spring 5 is sheathed on the push rod 4. The lower end of the spring 5 is in contact with the boss at the inner lower part of the sleeve 6, and the upper end is in contact with the boss at the upper end of the push rod; the lower end of the push rod 4 passes through the sleeve 6, first A fixed nut 7 is connected, and a collision block 8 is fixed at the end. The push rod 4 drives the collision block 8 to reciprocate to control the opening and closing of the travel switch 1, so that the travel switch generates a signal and transmits it to the electric control system.

Sleeve 6 is provided with connection plate 9, and one side of connection plate 9 is fixed with fixed plate 2, and the other side is fixed with sleeve 6, and connection plate 9 and sleeve 6, fixed plate 2 all are fixed by welding.

The connection plate 9 and the travel switch 1 are welded on one side of an adjustment plate 3, and the other side of the adjustment plate 3 is fixed to the fixed plate 2; the fixed plate 2 is provided with a positioning hole 11; the adjustment plate 3 is provided with a positioning hole 11 Relative to the positive bar-shaped hole 12 , an adjusting bolt 10 is passed between the positioning hole 11 and the bar-shaped hole 12 . Adjust the position of the adjustment plate 3 according to actual needs, and then use the adjustment bolt 10 to pass through the strip hole 12 on the adjustment plate 3 and the positioning hole 11 on the fixing plate 2, and fix the adjustment plate 3 and the fixing plate 2 on the support of the production line to make the ejector pin 4 work normally. This is also convenient for production lines suitable for different models.

The lower end of the push rod 4 is provided with a screw thread matched with the fixed nut 7 , and the end is fixedly connected with the bumper 8 through thread fit.
