Abstract
The utility model discloses a portable platen. The platen body comprises two side vertical plates and connecting pieces. The connecting pieces of the both ends of the platen body are contacted with the workpieces through half cylindrical surface. The upper flat surface of the platen body is provided with a plurality of half cylindrical grooves which are parallel and whose radiuses are equal, and the grooves are matched with the half cylindrical part of the both ends of a hinged beam. The portable platen of the utility model has reasonable distribution of materials, the utility model has the advantages of light weight, convenience and simpleness, and low cost, the distance between the boosting point of stud and the clamped object can change, and the height of the rear spacer block of the platen is irrelevant with the height of workpieces when the workpieces are clamped, the utility model can be selected arbitrarily, and doesn't add the spacer block under the majority of condition.
Description
The utility model belongs to a kind of clamping tool that makes things convenient for.
Known this type of pressing plate, as shown in Figure 1 and Figure 2.Pressing plate body (11) two ends are the semi-cylindrical projection, there is half cylindrical grooves in pressing plate body stage casing, half-cylindrical hinged beam (12) promptly embeds in this groove, by double-screw bolt (13), nut (14) and T type groove nut (15) workpiece or mould (16) is clamped on the workbench (17).
This known pressing plate has following shortcoming: distribution of material is unreasonable, and intermediate groove partly is subjected to the moment of flexure maximum and the bending resistant section coefficient is less, and the centre is porose again; Other is subjected to the less position of moment of flexure but is solid, and this has just expended many materials meaninglessly.The distance at the position of double-screw bolt (13) and pressing plate body (11) both ends is a certain value, causes the adaptability of a distance that is installed relatively poorly, and it is not too convenient to use, and pressing plate body (11) is the hot forging forging, and the technology cost is higher.
The utility model aims to provide a kind of pressing plate that makes things convenient for that following characteristics are arranged: according to the stressed size of each several part, and reasonable distributed material, weight reduction when improving intensity; Adaptability to a distance that is installed is strong, uses more convenient; Production technology is simple, productivity ratio height, low cost.
For achieving the above object, the utility model has been taked following solution: make things convenient for pressing plate, formed by pressing plate body, hinged beam, double-screw bolt, nut and T type nut, have semi-cylindrical recesses on the last plane P of pressing plate body, hinged beam and this groove fit, double-screw bolt one end links to each other with workbench by T type nut, and the hole that the other end passes pressing plate body and hinged beam cooperates with nut.Two parallel cant boards connect through connector, constitute the pressing plate body, are in the connector at pressing plate body both ends, contact with being pressed the surface with one section face of cylinder, keep the space that needs between the vertical plates on both sides.
A preferred version of the present utility model: on the position that plane P on the pressing plate body does not interfere with connector, have the semi-cylindrical recesses that several are parallel to each other, and the radius of each groove is identical.
Second preferred version of the present utility model is: hinged beam is formed by having common three sections of going up the plane, interlude has bigger sectional area, there is a through hole perpendicular to last plane at its center, the both sides section is the half round post with same radius, and its radius is identical with semi-cylindrical recesses on the pressing plate body.
Below in conjunction with embodiment of the present utility model, elaborate solution of the present utility model.Additional disclosure once, the utility model has more than and is limited to following embodiment.
Accompanying drawing 3, Fig. 4, Fig. 5 give out an embodiment of utility model.Pressing plate body (1) is welded by two cant boards (1-1) and connector (1-2,1-3), keeps needed space between the vertical plates on both sides.There is one section outstanding face of cylinder at pressing plate body (1) both ends, this face of cylinder is contacted with pressing the surface, on plane P on the pressing plate body, the position that interferes with connector (1-3) not, leave three semi-cylindrical recesses parallel to each other, each groove radius is all identical, hinged beam (2) divides three sections, middle one section has larger cross-section, to guarantee enough intensity, there is a through hole perpendicular to last plane at its center, and two ends respectively are half-cylindrical for two sections, its radius is identical, and identical with the radius of the last plane P upper groove of pressing plate body (1); Three parts of hinged beam have common last plane, double-screw bolt (3) one ends are connected with workbench by T type nut, the hole that the other end passes hinged beam (2) cooperates with nut (4), according to the difference that clamps height, hinged beam (2) can select one of three semi-cylindrical recesses on the last plane of pressing plate body (1) to cooperate with it, the double-screw bolt distance that adds force and workpiece can be regulated like this, uses more convenient.
Fig. 6, Fig. 7 are the another kind of structures that the utility model makes things convenient for the pressing plate body of pressing plate, and the connector (1-2) that two cant boards are coupled together is the riveting post, and all the other are all identical with previous embodiment.
The utility model has the advantages that: adopting the riser structure, can effectively increase bending coefficient, is neutral gear between the vertical plates on both sides, and distribution of material is reasonable, and intensity is good and in light weight; Have several grooves on the upper plane P of pressing plate body (1), can adapt to the distance of Workpiece clamping and highly in a wider context variation; Hinged girder construction is more reasonable; Adopt plate combination structure, the method production that available cold punching is cut out, productivity ratio improves greatly, and process costs reduces.
Accompanying drawing 1, accompanying drawing 2 are known pressure plate structures, among the figure: 11, pressing plate body, 12, hinged beam, 13, double-screw bolt, 14, nut, 15, T-shaped nut, 16, workpiece, 17, platen.
Accompanying drawing 3 is structures that the utility model makes things convenient for pressing plate, and Fig. 4 is the A-A profile; Fig. 5 is the B-B profile. Among the figure: 1, pressing plate body, 2, hinged beam, 3, double-screw bolt, 4, nut, 5, T-shaped nut, 6, workpiece, 7, platen, 1-1, cant board, 1-2,1-3, connector.
Accompanying drawing 6 is another kind of structures that the utility model makes things convenient for the pressing plate body of pressing plate, and Fig. 7 is the C-C cutaway view, among the figure: 1-1, cant board, 1-2, connector.
