By applying the technical scheme of the invention, the pressing surface of the pressing plate, the upper surface and the lower surface of the workpiece and the upper surface of the base are kept parallel by virtue of the clearance fit of the pressing plate main body and the round hole of the base, the axis of the pressing plate main body 1 is kept coincident with the axis of the hole 13, and the pressing surface 11 is kept parallel to the upper surface 12 of the base, so that the plane contact of the pressing surface 11, the upper surface 12 of the base and the plane of the workpiece 15 is realized, the reliability of the clamp is improved, the clamping deformation is reduced, and the problems of indentation and the.
Wherein, the pressure plate main body 1 can be a cylindrical structure; correspondingly, the hole 13 on the base 6 which is in clearance fit with the pressure plate main body 1 is a circular hole. In addition, the base 6 may have a cylindrical structure, a square structure, or a rectangular parallelepiped structure. Fig. 2 shows that the platen base 6 has a cylindrical structure, and fig. 3 shows that the platen base 6 has a rectangular parallelepiped structure. In addition, the axial dimensions of the platen body, the base circular hole, and the connecting member may be determined by the thickness range of the portion of the workpiece 15 to be pressed, which is not limited by the present invention.
It will be understood by those skilled in the art that the above description of the structure of the platen body 1, the aperture 13 and the base 6 is merely exemplary and not intended to limit the present invention.

For example, after the pressing plate body 1 is pressed into the hole 13 of the base 6, the fastening bolt passes through the elastic pad 4, the flat pad 5, the through hole 8 in the pressing plate body 1, the spring 2 in sequence, and the lower part of the spring is screwed into the threaded hole or the wire thread insert 15 at the bottom of the round hole of the base, so that the workpiece is pressed between the bottom surface of the lug and the upper surface of the base, that is, the bottom surface of the lug is pressed against the surface of the workpiece, and the upper surface of the base is used for supporting the workpiece when the workpiece is pressed. At this time, the head of the bolt (i.e., the upper portion of the connector) is seated in the top counterbore 10 provided with the flat pad 5 and the elastic pad 4.
In addition, in another embodiment, as shown in fig. 2-3, the pressure plate base 6 may be designed as a general clamping worktable, and a plurality of array-type circular holes matched with the cylindrical structure of the pressure plate main body are designed on the general clamping worktable. The position for placing the pressing plate and the number of the pressing plates can be selected according to the shape of the workpiece 15, and the length of the cylindrical structure of the main body of the pressing plate and the length of the bolt can be determined according to the height of the workpiece pressing part. The pressing plate can be suitable for clamping workpieces with various heights within the allowable range of the matching length of the outer cylinder of the pressing plate main body and the round hole of the base and the length of the connecting piece, and the generalization of the pressing plate is realized.
In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
