Abstract
Description
The present invention relates to a lift for an automobile body assembly process, and in particular, the structure is simple, easy to install and at the same time, the utilization of the installation space is high, the lifting and lowering operation is stable, and the driving part is not affected by the scattering of the spatter during welding work. The present invention relates to a vehicle body assembly process lift that is easy to maintain and maintain.
In general, a car goes through a process of assembling a number of devices and components until the finished product comes out, and the assembly process is performed by the workers using devices and devices, each part of the assembly line.
In particular, a car body of a car body is made of dozens of steel panels, each flange is joined by welding, the robots are installed at regular intervals along the assembly line where the conveyor line is installed, one operator to several robots It is managed by a computer, and the assembly line is automatically transferred according to the control of each computer, and a specific part of the vehicle body which is conveyed along the conveyor of the assembly line is point welded and joined by the robot controlled by the computer. have.
The vehicle body of the vehicle is mounted on the top of the skid lift to be transported to perform the next process after work.
A typical example of such a conventional skid lift is shown in FIGS. 1 and 2.
As shown in the figure, the skid lift moves downwards for work while supporting a
The
That is, in order to move the
Subsequently, when driving the
However, the conventional skid lift as described above is scattered while a lot of spatters are generated during welding, in which case the lift is scattered on the drive cam or the drive link operated by the rolling drive method using the link and welded at the same time.
In addition, the conventional skid lift has a large and heavy structure that requires lubricating oil to lubricate the joints and the guiding part of the link, and the structure is complicated, and requires a separate lift bed, resulting in a complicated structure and investment cost. There was an increasing problem.
Accordingly, the present invention has been made in view of the above-described problems of the prior art, so that the operation gap does not occur when the skid and the roller bed are transported up and down, so that the shaking for the vehicle body assembly process does not occur during the processing of the vehicle body. The purpose is to provide.
Another object of the present invention is to minimize the space for the elevating operation with a simple structure that can operate in the vertical direction without the rolling (link-type) movement.
In addition, another object of the present invention is to install the bellows at the same time the deceleration means and the lifting operation unit is installed in the case to prevent the spatter scattered during welding work to be introduced into the interior through the guide hole.
In addition, another object of the present invention is to select the speed reduction means as a gear drive method or a belt drive method, to increase the versatility to the sliding drive method for various lifting and lowering.
In order to achieve the above object, the present invention provides a roller bed that supports and transports a skid on which a vehicle body is mounted, and moves the lower part for work to move the upper part for transport after work. In the car body assembly process lift installed in the
The lift is provided with a motor to the outer side of the drive case is located on the upper side of the base bed, the deceleration means for reducing the rotational speed of the motor forms a drive unit is installed inside the drive case,
The guide hole is vertically formed to face the inner side of the roller bed, and the elevating case to which the guide rail is coupled along the vertical direction of the inner wall is installed on the other side of the driving case so as not to interfere with the guide hole.
The slewing shaft which is fastened and rotated to the deceleration means of the driving unit is installed upright inside the elevating case, and the guide block is fitted to move along the guide rail to the outside of the slewing bushing screwed to the slewing shaft, It is coupled to the bushing bushing and is formed through a guide hole of the elevating case to form an elevating operation portion consisting of a support bracket supporting the lower surface of the roller bed, so that spatters are scattered to the driving portion and the elevating operation portion when welding the vehicle body. It provides a vehicle body assembly process lift characterized in that the configuration is not welded.
As described above, the present invention has an effect of increasing the accuracy of the work by preventing the occurrence of operating gap during the vertical transfer of the skid and the roller bed so as not to shake during the machining operation of the vehicle body.
In addition, there is an effect that can minimize the installation space by minimizing the space for lifting and lowering operation with a simple structure that can operate in the vertical direction without the cloud (link type) movement.
In addition, the deceleration means and the elevating operation unit are installed in the case, and at the same time, the bellows can be installed to prevent spatter from scattering during the welding operation and to be introduced into the interior through the guide hole, thereby reducing the need for maintenance. .
In addition, the deceleration means can be selected as a gear drive method or a belt drive method, there is an effect to increase the versatility by the sliding drive system for various lifting and lowering.

At this time, when performing various welding operations such as spot welding or carbon dioxide (CO 2 ) welding, the molten metal of the welding rod or the wire is normally applied to the base metal of the welding part due to improper combination of current and voltage during welding or poor grounding of the earth. Sputtering sputtered in all directions without being welded or partially melted or lightly attached in the form of small lumps around them occurs.
When the spatter is scattered and fused, it may cause a malfunction of the device or hinder the smooth operation. In the present invention, the speed reduction means 63 is installed inside the
