As shown in FIG. 4 and FIG. 5 , the upper pressing part includes a first base plate 3 sleeved on the guide column 5 , the bottom surface of the first base plate 3 is provided with a positioning block 8 , and the two ends of the first base plate 3 pass through the sliding slides opened on the bottom surface of the first base plate 3 . The rail 20 is mounted with two sliders 4 . A first spring 15 is installed between the end of the slider 4 near the center of the first base plate 3 and the first base plate 3 , and the end of the slider 4 away from the center of the first base plate 3 is matched with the inclined surface. The arc portion 18 of the slider 4 is located at the end of the slider 4 near the center of the first base plate 3 as a support portion 19 which is located below the first base plate 3 and cooperates with the protrusion at the end of the rubber pad 2 .

The working principle of this pressing tool is:

Under the action of the external drive mechanism, the first base plate 3 reciprocates linearly along the guide column 5, and the press-fit installation of a rubber pad 2 and the workpiece is completed after one reciprocation cycle.

In a reciprocating cycle, first, install the workpiece on the workpiece mounting seat, and install the rubber pad 2 on the pressing part (by holding and moving the rubber pad 2 until the top edge of the rubber pad 2 abuts against the positioning block 8, The protrusion on the end of the rubber pad 2 is located at the set position between the support part 19 and the bottom of the first substrate 3 (the rubber pad 2 remains stationary under the support of the support part 19 , the installation of the rubber pad 2 is completed).

Then, under the action of the external driving mechanism, the first base plate 3 moves downward along the guide column 5, and the first base plate 3 drives the positioning block 8, the slider 4 and the rubber pad 2 to move downward synchronously. During the downward movement, under the action of the slope of the vertical top block 6 , the sliding block 4 moves along the sliding rail 20 in a direction away from the center of the first base plate 3 , so that the rubber pad 2 is separated from the support portion 19 and then moves away from the center of the first base plate 3 . The substrate 3 is pressed into the workpiece.

Finally, under the action of the external drive mechanism, the first base plate 3 moves upward along the guide column 5, and the first base plate 3 drives the positioning block 8 and the slider 4 to move upward synchronously. During the upward movement, the action of the first spring 15 Next, the slider 4 moves to the initial position along the slide rail 20 in a direction close to the center of the first base plate 3 , so as to prepare for the installation of the next rubber pad 2 .

As shown in FIG. 4 and FIG. 5 , in order to facilitate the quick installation of the workpiece and avoid the workpiece mounting portion from affecting the pressing of the rubber pad 2, the base 9 includes a base and a support plate 12 mounted on the base and having a first through hole; The workpiece mounting part includes a first limit block 13 with a T-shaped cross section, a step matching the first limit block 13 is arranged on the first through hole, and a first through hole located between the first limit block 13 and the base A second spring 14 is placed in it.

When the workpiece needs to be installed, under the action of the second spring 14, the first limiting block 13 extends to the outside of the top surface of the support plate 12, so as to facilitate the rapid positioning and installation of the workpiece. When the cavity in the workpiece for accommodating the rubber pad 2 is circular, the outer contour of the cross-section of the portion of the first limiting block 13 outside the support plate 12 is also circular in size.

In addition, in order to further speed up the installation speed of the workpiece, the top edge of the first limiting block 13 is provided with a chamfer, and the first limiting block 13 is provided with ventilation holes.

Correspondingly, for the case where there is a gap on the annular protrusion of the rubber pad 2 as shown in FIG. 8 , in order to realize the accurate pressing of the rubber pad 2 and the support seat 7 as shown in FIG. 9 , the installation of the rubber pad 2 is accelerated. Speed on the upper nip. The upper pressing part also includes a second limiting block 16 with a T-shaped cross section and a second base plate 1 mounted on the top surface of the first base plate 3 (the first base plate 3 and the second base plate 1 are connected by a screw pair). The side of the two substrates 1 close to the first substrate 3 is provided with a groove for installing the second limiting block 16 , and a third spring 17 is placed between the end of the second limiting block 16 close to the first substrate 3 and the groove. One end of the limiting block 16 away from the first base plate 3 penetrates through the strip hole opened on the first base plate 3 .

When installing the rubber pad 2 on the upper pressing part, hold and move the rubber pad 2 to the gap between the support part 19 and the first substrate 3 (it is not necessary to extend the gap on the rubber pad 2 to the second limit block 16 ). to the part below the first base plate 3 ), until the rubber pad 2 cannot move forward under the action of the positioning block 8 . If initially, the above two have been aligned and engaged, the installation of the rubber pad 2 and the upper pressing part is completed; The part is pushed into the strip hole on the first base plate 3 by the rubber pad 2), rotate the rubber pad 2 until under the action of the third spring 17, the aforementioned two are aligned and engaged, and the rubber pad 2 and the upper pressing part are completed. installation.
