Description

A mobile workbench for machine tools

technical field

The utility model relates to a machine tool workbench, in particular to a mobile workbench which can help to quickly install and align the mold center.

Background technique

Existing molds for stamping, especially in the automotive industry, the molds weigh tens of kilograms and weigh several tons. If they are manually transported and installed, they are not only cumbersome, but also extremely inefficient, labor-intensive and time-consuming, and are often damaged by collisions. It affects the accuracy of the equipment; if it is hoisted by a crane, it will be limited by the rope and the structure of the machine tool, which will not only force the slider on the machine tool on one side, affect the accuracy of the slider and the guide rail, but also make it difficult to align the center.

Utility model content

The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a device that saves labor and time, is easy to operate, safe and reliable, and can be quickly installed and aligned to the center of the mold.

The purpose of this utility model is achieved through the following technical solutions.

A mobile workbench for a machine tool includes a movable workbench. The utility model is provided with lateral position-limiting and guiding devices on both sides of the movable workbench.

The movable workbench is superimposed on the machine tool workbench, and can be relatively moved by means of rollers arranged on the machine tool workbench.

The lateral limit guiding device is composed of two parallel guide rails, each of which is provided with a set of rollers on the inner side.

There are at least 3 rollers in each group. The rollers may be rolling bearings.

The middle part of the movable worktable is provided with a mold center alignment mechanism.

The guide distance of the lateral limit guide device shall at least ensure that when the movable worktable moves into the machine tool, the center of the mold placed on the movable worktable can be aligned with the center of the machine tool slider; When the table plate moves out of the machine tool, the mold can be completely out of the projection area of the slide. The guide distance can ensure that the movable worktable can be moved into the machine tool to accurately align the mold to the center, and can be easily assembled and disassembled when it is moved out of the machine tool.

On the rear side of the plane of the machine tool worktable, a longitudinal positioning device for the movable worktable is arranged. The longitudinal positioning device can make the longitudinal positioning of the movable workbench on which the mold is installed fast and accurate.

On the front side of the plane of the machine tool workbench, a movable workbench plate retreat limit device is arranged. The retreat limit device sets a reasonable stroke for the movable worktable to move out of the machine tool.

A movable workbench auxiliary jacking column is provided on the side of the retreat limiting device. The auxiliary jacking column is a jack-type structure, and a roller is provided on the upper end of the jacking column. The purpose of arranging the auxiliary top column is to make the support of the movable workbench stable when it is moved out, and help to reduce the movement resistance of the movable workbench.

A group of fixture mounting holes are arranged longitudinally and transversely on the upper surface of the movable worktable.

The use process of the mobile workbench includes, firstly, lifting the production mold to the movable workbench, and aligning and placing it in place according to the center position at one time; secondly, guided by the lateral limit guide devices on both sides, the movable The worktable and the mold are pushed into the machine tool, and moved into place based on the longitudinal positioning device on the rear side, and then the machine tool control device is operated to unload the rollers on the machine table; finally, the pressure plate is fixed and the installation is completed.

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

1. The rollers on the machine tool workbench are only in contact with the lower plane of the movable worktable, so there will be no blockage of the pulleys when moving the mold before, which is simple and reliable;

2. Avoiding the disadvantages of unilateral force on the machine tool and affecting the accuracy when the mold is pulled and lifted by the previous driving, it is safe and safe;

3. When the mold is placed on the movable worktable, it will be aligned to the center immediately, avoiding the need to use the pry bar to adjust after the mold is pulled in, which often has the defect of bumping and damage, saving time and effort;

4. Reduce the time and difficulty of assembling and disassembling the mold, improve production efficiency, high quality and high efficiency;

5. Reduce labor intensity.

Detailed ways

In FIG. 1 , a movable worktable 2 is superimposed on the machine tool workbench 1 , and can be relatively moved by means of rollers 3 arranged on the machine tool workbench 1 .

Both sides of the movable worktable 2 are provided with lateral limit guide devices, which include two parallel guide rails 4, and each guide rail 4 is provided with a set of rollers 5 on the inner side, the rollers 5 are rolling bearings, and each set of rolling bearings There are 30 pieces.

The middle part of the movable worktable 2 is provided with a mold center alignment hole 6 .

The guiding distance of the lateral limit guide device is that when the movable worktable 2 moves into the machine tool, the mold center of the movable worktable 2 can be aligned with the hole 6 to the center of the machine tool slider; When the worktable 2 moves out of the machine tool, the mold can be completely separated from the projected area of the slide block.

On the plane rear side of the machine tool workbench 1, a longitudinal positioning device 7 of the movable workbench plate 2 is arranged. On the plane front side of the machine tool workbench 1, there is provided a retreat limiting device 8 of the movable workbench plate 2. The side of retreat limiter 8 is provided with movable workbench 2 auxiliary jacking columns 9, and auxiliary jacking columns 9 is a jack type structure, and the upper end of jacking columns is provided with roller.
