Detailed ways

The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

The pad adjusting device of the present invention is mainly designed for the processing needs of irregular workpieces in the field of mechanical processing. When processing these irregular workpieces, it is impossible to directly clamp them with a vice. When fixing the workpieces, it is generally necessary to use another pad The block provides a fulcrum, and then use the pressing block to press the workpiece for processing. Because the height of the processing part of the workpiece to be processed is different or when other workpieces need to be processed, it is often necessary to adjust the height of the cushion block to meet the needs of the pressing block to press the workpiece. The pad adjusting device of the present invention is to use the pad body to slide freely up and down on the column to ensure the required fulcrum height, and then use the fixing mechanism to fix the pad body on the corresponding position of the column. Fix the workpiece on the workpiece and the block body.

As shown in FIG. 1 , the pad adjusting device provided in this embodiment includes: a pad body 1 , a column 2 , an adjusting mechanism and a fixing mechanism 4 . In this embodiment, the adjustment mechanism is specifically the adjustment screw 3 , which will be described as the adjustment screw 3 in the following. The spacer body 1 is set on the column 2 and can slide up and down. The spacer body 1 provides a support surface to support the pressure block 5 (see Figure 7). The spacer body 1 slides up and down on the column 2 to ensure that the spacer The height of the fulcrum is adjusted by adjusting the screw rod 3. When the block body 1 is in the required position, it is fixed on the column 2 by the fixing mechanism 4; the bottom end of the column 2 is provided with a base 21 (see Fig. 6) Both ends of the base 21 are provided with slots 22, and the base 21 is fixed on the workbench through the slots 22 with bolts (not shown in the figure).

As shown in FIG. 2 , the spacer body 1 is in the shape of a block, and may also be in other shapes. In this embodiment, it is necessary for it to slide up and down on the column 2 and to provide a support. A cavity 11 is provided in the middle of the block body 1, which is a square hole. The block body 1 is set on the column 2 through the cavity 11 and slides up and down. In order to cooperate with the square hole, the column 2 is designed as a square structure, or Only the sliding section between the block body 1 and the column 2 is designed as a square structure; the rear end of the block body 1 is provided with an adjusting screw hole 13, and the adjusting screw 3 is arranged on one side of the column 2, and the adjusting screw hole 13 cooperates with the adjusting screw 3. The driving end of the adjusting screw 3 is provided with a second through hole (not marked in the figure), and the second through hole is equipped with a second driving rod 31 (see Figure 1). When working, use the second driving rod 31 to rotate the adjusting screw 3 Rotate, the block body 1 can move up and down under the thread drive, so that the height of the block body 1 can be adjusted, and fulcrums of different heights are provided according to the different positions of the block body 1 on the column 2.

As shown in Figures 3 to 5, when the spacer body 1 is in the required position on the column 2, the spacer body 1 is fixed on the column by the fixing mechanism 4, and its fixing effect is realized in this way, on the spacer body 1 There is an inclined hole 12 (see Figure 2), which intersects with the square hole, and the front end of the inclined hole 12 is a threaded hole 121 (see Figure 2); The cylindrical pin of 411 is provided with T-shaped slot 412 at the tail end of latch 41; The matching T-shaped bump 421, the other end of the lock bar 42 is provided with a first through hole 422, and the first driving lever 43 (see Figure 1) is installed in the first through hole 422. When in use, the T-shaped bump 421 and The T-shaped slot 412 is matched and connected, the bolt 41 is inserted into the inclined hole 12 and the inclined surface 411 is aligned with the surface of the column 2, the first lever 43 rotates the lock lever 42 to rotate, the lock lever 42 drives the bolt 41 to move through the thread, and the block body 1 passes through the bolt 41 extrusions are fixed on the column 2.

As shown in Figure 7, when using this device, according to the specific shape and processing height of the workpiece 7, use the adjusting screw 3 to adjust the specific height of the pad body 1 on the column 2, and then use the fixing mechanism 4 to hold the pad body 1 Fix it on the column 2, then use one end of the pressing block 5 to press on the workpiece 7, and the other end to press on the block body 1, and finally, use the pressing bolt 6 to compress the pressing block 5, and the pressing block 5 to press the workpiece, In this way, the workpiece 7 is fixed on the workbench and waits for processing.
