Description

Technical Field

[0001] The utility model relates to the technical field of automobile welding production line equipment, in particular to a device for detecting nuts after welding nuts and taking out stamping parts. Background Art

[0002] At present, the nut welding on the automobile welding production line must be sensed after it is completed. Generally, there are two ways to directly sense the nut: one is to sense inside the subsequent station fixture after the nut welding is completed, and the other is to design a separate sensing column to sense the nut after welding. According to the site layout and production rhythm, a robot needs to grab two identical stamping parts from the PLT at the same time, sort them at the sorting station first, then re-grab them, weld the nuts, check whether the nuts are present after welding, and finally put them on the slide to take them away. However, the existing technology has the following shortcomings when used:

[0003] Considering the on-site layout, adding a nut sensing station or sensing column will result in insufficient on-site space, making it difficult to actually operate, which has certain limitations and high production costs.

[0004] Therefore, there is an urgent need for a device for inspecting nuts after welding and removing stamping parts to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to add a nut sensing station or a sensing column to address the current problems of insufficient on-site space, difficulty in actual operation, certain limitations, and high production costs due to the on-site layout.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0007] A device for inspecting nuts and taking out stamped parts after welding nuts is provided to improve the above problems.

[0008] The specific application is as follows:

[0009] A device for inspecting nuts and removing stamped parts after welding nuts, comprising a base, wherein the base is provided with symmetrically distributed rotating parts, the tops of the two rotating parts are fixedly connected to an upper frame, the upper frame is provided with an induction switch, the upper frame is provided with a limiting mechanism, the limiting mechanism includes three locations A, B, and C, the limiting mechanism includes a first driving cylinder, the first driving cylinder is provided with a first cylinder body support and a first cylinder rod support, the first cylinder rod support is provided with a limiting rod, the upper frame is provided with a symmetrically distributed induction mechanism, the induction mechanism includes a second cylinder body support fixedly connected to the upper frame, the second cylinder body support is provided with a second cylinder rod support, the second cylinder rod support is fixedly connected to four sensor brackets, the sensor bracket is provided with a sensor, and a second driving cylinder is provided at the bottom of the second cylinder rod support.

[0010] As a preferred technical solution of the present application, the upper frame is provided with symmetrically distributed sliding bars.

[0011] As a preferred technical solution of the present application, symmetrically distributed side guide plates are fixedly connected to the upper frame.

[0012] As a preferred technical solution of the present application, the first cylinder body support is installed on the upper frame.

[0013] As a preferred technical solution of the present application, a placement box is fixedly connected to the base.

[0014] As a preferred technical solution of the present application, both the front and rear surfaces of the base are fixedly connected with symmetrically distributed mounting blocks, and the mounting blocks are provided with mounting holes.

[0015] As a preferred technical solution of the present application, the first driving cylinder is electrically connected to the induction switch.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the scheme of this application:

[0018] By setting the induction switch, the first driving cylinder, the first cylinder body support, the first cylinder rod support, the second cylinder body support, the second cylinder rod support, the sensor and the second driving cylinder, firstly, the first driving cylinder is in an extended state, and the second driving cylinder is in a retracted state. After the stamping parts are welded with the nuts, the robot simultaneously grabs two identical stamping parts and places them on the upper frame, blocks the stamping parts with the limit rod, and then the second driving cylinder is extended, and the sensor senses the welded nuts through the second cylinder rod support. After the induction is completed, the second driving cylinder is opened, and the first driving cylinder in the limit mechanisms at A and B is opened, and the stamping parts slide downward. When the stamping part continues to slide downward, it touches the induction switch, and the first drive cylinder in the limit mechanism at C opens. The stamping part continues to slide downward until it is finally taken out, thereby reducing the number of workstations in the existing layout. At the same time, through integration, a simple cylinder rotation mechanism is added to meet production needs and reduce production costs. This solves the problem in the prior art that considering the on-site layout, a nut sensing station or a sensing column is added, the on-site space is insufficient, and it is difficult to actually operate. There are certain limitations and the production cost is high. BRIEF DESCRIPTION OF THE DRAWINGS
