During the processing, a supporting base plate is needed to support the workpiece. At the same time, because most workpieces have small size differences, these workpieces will share a base plate. This type of base plate is suitable for processing workpieces of different sizes and is called a common base plate tooling.

[0003] Small punching machines often require riveting, stamping, shaping and other tasks. Generally, due to the small size of parts or the need to place multiple parts on a jig or mold, it is very unsafe and inconvenient to operate directly under the punch press. Therefore, a sliding safety shared bottom plate for small punching machines is proposed to solve the above problems. Utility Model Content

[0006] Furthermore, the bottom plate is in the shape of a rectangular plate, and a mounting hole is provided inside the bottom plate.

[0007] Furthermore, an adjusting screw block is fixedly connected to the top of the base plate, the adjusting screw block is fixedly connected to the top of the base plate by a first bolt, and the stop block is fixedly connected to the top of the base plate by a second bolt.

[0008] Furthermore, the cross-section of the two linear slide rails is I-shaped, and the interiors of the two vertical slide posts are provided with I-shaped grooves, and the two vertical slide posts are located on the outer surfaces of the two linear slide rails through the I-shaped grooves.

[0009] Furthermore, connection screw holes are provided inside the two vertical sliding columns, and the two vertical sliding columns are fixedly connected to the inside of the sliding plate by countersunk bolts.

[0010] Furthermore, a handle is fixedly connected to the top of the push-pull plate, a circular mounting hole is opened inside the sliding plate, and the two quick-change pressure plates are both detachably connected to the top of the sliding plate.

[0011] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0012] This small punch press uses a sliding safety shared base plate. When the jig is punching, it is placed in the circular mounting groove inside the sliding plate, and then pressed and fixed by the quick-change pressure plates on both sides. The jig is very convenient to replace. After replacing the jig, it can be used without adjusting the mold. The linear slide rail adopts linear bearings with high positioning accuracy and is easy to use. The vertical slide column at the bottom of the sliding plate relies on the internal I-shaped groove to contact and rub with both sides of the linear slide rail, and the top is in a floating design to achieve the stability of the floating structure. The linear slide rail is not subjected to force during stamping, which protects the guide rail and increases its service life; the adjusting screw block and the block play the role of left and right limiters to ensure that the sliding plate is always at the top of the linear slide rail. After using the base plate, the jig or mold base is standardized, the jig is simplified and the jig replacement is quick and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
