Detailed Description

In order to make those skilled in the art better understand the technical solution of the present application, the following further describes the technical solution of the present application with reference to the drawings and the embodiments.

Referring to fig. 6-8, a large area plate suspension machining support device is shown, wherein the plate is horizontally suspended and clamped on a machine tool workbench. As shown in fig. 1, 4 and 7, the machine tool table is of a horizontal rotation driving structure, and a plurality of inverted T-shaped grooves 70a for assembling and clamping a machined workpiece are arranged on the surface of the machine tool table at intervals along the circumferential direction.

The supporting device comprises an assembling connecting part and a supporting part, wherein the assembling connecting part is connected and fastened with the machine tool workbench, and a supporting base point of a large-area plate body is realized.

The supporting component is arranged on the top of the assembling and connecting component and is supported by clinging to the bottom surface of the plate body in a horizontal suspension state. At assembly adapting unit with under the fastening state is connected to the lathe workstation, carry out even interval through the plate body bottom surface of support component and suspension centre gripping and support, improve the support intensity that plate body central point put under the suspension state to overcome the cutter and add great processing external force and cause the problem of plate body downwarping man-hour, thereby keep the plate body and add the level and smooth intensity of surperficial man-hour, and then improve the machining precision, also avoid simultaneously to the plate body add the large-scale contact wear that the surface caused man-hour.

As shown in fig. 7-8, the fitting connection component comprises a fastening pulling plate 1 which is slidably embedded in the machine tool workbench, and a pressure plate 2 which extends to the surface of the machine tool workbench and is in close contact with the surface is threaded in the fastening pulling plate. Slide embedding to the workstation with fastening arm-tie 1 in the groove of falling T type and slide to the position department that the plate body bottom needs the support, after that with clamp plate 2 and fastening arm-tie 1 threaded connection (clamp plate 2 bottom is provided with the screw rod 21 that the screw thread wore to establish in fastening arm-tie 1, fastening arm-tie 1 restricts its rotation through the clearance fit with the groove of falling T type, and then accessible rotating pressing plate 2 realizes the fastening, make clamp plate 2 compress tightly on the workstation surface simultaneously, fastening arm-tie 1 hugs closely the interior top surface in the groove of falling T type, the realization is fixed to plate body bottom sprag point.

As shown in fig. 7-8, the supporting member is a telescopic column 3 vertically fixed on the top surface of the pressing plate 2, and includes an upper column 31 and a lower column 32 which are connected by screw threads. After the pressing plate 2 is rotated to be in close contact with the surface of the worktable, the upper cylinder 31 is rotated to move upwards relative to the lower cylinder 32 to be in close contact with the bottom surface of the plate body, so that the bottom surface of the plate body in a suspended and clamped state is supported.

When the upper surface of the plate body is firstly machined (for example, by milling), the lower surface of the plate body is in an unprocessed state, which is a blank structure, so that the plane precision of the lower surface is poor, and therefore, the top surface of the upper cylinder 31 cannot be in close contact with the lower surface of the plate body, which not only causes the deficiency of support stability, but also causes rigid mechanical damage to the lower surface of the plate body (the side line of the upper cylinder 31 can be in contact with the lower surface of the plate body to cause a pit) in an inclined contact support state, and therefore, in order to solve the problem, as shown in fig. 8, a flat support plate 4 which is close to the bottom surface of the plate body is arranged at the top end of the upper cylinder 31 in a three-dimensional rotating manner. Under the supporting force effect provided by the upper column body 31, the flat-pasting supporting plate 4 at the top end can be tightly pasted on the lower surface of the plate body under the structure rotating in the space, so that flat-pasting contact and stable support with the lower surface of the plate body are realized, and the problems of unbalanced supporting force and contact damage caused by uneven surface of the plate body are solved.

The principle of this application is: when the supporting device is used, the fastening pulling plate 1 is firstly embedded into the inverted T-shaped groove of the workbench in a sliding mode and slides to the position needing to be supported at the bottom of the plate body, then the pressing plate 2 is in threaded connection with the fastening pulling plate 1, and meanwhile the pressing plate 2 is tightly pressed on the surface of the workbench, the fastening pulling plate 1 is tightly attached to the inner top surface of the inverted T-shaped groove, and the bottom supporting point of the plate body is fixed. The upper cylinder 31 is then rotated and moved upward, so that the flat support plate 4 is in flat contact with the lower surface of the plate body and stable support is achieved.

The foregoing shows and describes the general principles, essential features, and advantages of the application. Without departing from the spirit and scope of this application, there are also various changes and modifications that fall within the scope of the claimed application.
