Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a movable sheet metal limiting mechanism. Background Art

[0002] Sheet metal parts are metal parts formed by sheet metal processing and stamping. Their materials mainly include steel plates, stainless steel, aluminum alloys, etc. Sheet metal limiter is a device used in the sheet metal processing process to accurately position and fix sheet metal parts. The use of this limiter can greatly improve the stability and accuracy of sheet metal processing, thereby improving product quality.

[0003] A sheet metal clamping and limiting mechanism disclosed in the Chinese utility model patent application disclosure specification CN213858202U controls the electric cylinders on its first limiting mechanism and the second limiting mechanism to drive the clamping plate to clamp and limit its sheet metal. When the sheet metal needs to be loosened, the electric cylinder is turned off, and then the telescopic spring at the end of its fixed plate drives the clamping plate to retract, thereby loosening the sheet metal. The clamping and limiting mechanism has a simple and reasonable structure, is easy to manufacture, and is convenient to operate. However, the sheet metal limiting mechanism has low flexibility in use. After a single sheet metal processing operation, it is not convenient to quickly adjust the position of the limiting mechanism, thereby affecting the subsequent processing efficiency of the sheet metal.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This movable sheet metal limiting mechanism has a bidirectional shaft motor installed at the middle position on both sides of the working chamber. When the bidirectional shaft motor is started, the threaded rods on both sides can be driven to rotate. At this time, the first threaded block on the bottom threaded rod can push the universal wheel to extend from the bottom end of the working chamber through the first fixed seat, and the second threaded block on the top threaded rod can push the second fixed seat to extend from the top end of the working chamber to clamp the sheet metal. At the same time, the position of the sheet metal limiting mechanism can be quickly moved through the universal wheel. The operation is simple and convenient. At the same time, the universal wheel and the second fixed seat can be put into the working chamber when the sheet metal limiting mechanism is not in use, thereby improving the flexibility and convenience of using the sheet metal limiting mechanism.

When the clamping piece is sleeved on the outside of the connecting seat, the connecting seat and the clamping piece can be assembled by inserting the card blocks into the card slots on the clamping piece. When the clamping piece needs to be replaced according to the clamping needs of sheet metal pieces of different specifications, the card blocks on the connecting seat can be pulled out of the card slots and retracted into the inside of the connecting seat by pulling the clamping piece. At this time, the clamping piece can be quickly replaced, thereby improving the applicability of sheet metal clamping. BRIEF DESCRIPTION OF THE DRAWINGS
