Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows: referring to fig. 1 and 2, a machine tool with a material supporting device comprises a machine tool body 1, wherein two sets of center supporting assemblies 2 which are arranged oppositely are arranged on the machine tool body, a product positioning space 3 is formed between the two sets of center supporting assemblies, a cutter assembly 4 is arranged above the product positioning space, a material supporting mechanism is arranged right below the product positioning space and comprises a supporting plate 5 and a driving mechanism, the bottom of the supporting plate is vertically movably connected with the machine tool body through a support 6, and a plurality of groups of bearings 7 are rotatably arranged in the middle of the support;

the driving mechanism comprises a hydraulic cylinder 8 and a push plate 9, the hydraulic cylinder is arranged on the rear side of the support, the rear end of the push plate is connected with an output shaft of the hydraulic cylinder, and the push plate is arranged opposite to the bearing;

In this embodiment, when in-service use, during the material loading, hoisting machine constructs earlier in hoisting the work piece to product location interval, the bottom of work piece supports on the layer board, then the output shaft of pneumatic cylinder stretches out, it moves forward to drive the push pedal, at this in-process, because the top surface of push pedal is the spigot surface, therefore, spigot surface and bearing contact, it moves up to promote bearing and support, make the both ends location department of product can be just facing two sets of central support subassemblies, then reuse central support subassembly fixes a position the product, the pneumatic cylinder drives the push pedal and moves backward, the layer board then moves down, break away from the product. The center supporting assembly is a mechanism capable of moving left and right and rotating and is used for positioning and rotating a product, the center supporting assembly drives the workpiece to rotate, and the product is machined by the cutter assembly. During blanking, the hydraulic cylinder pushes the supporting plate to move upwards through the push plate, after the product is supported by the supporting plate, the central supporting components at two ends are separated from the product, the supporting plate descends again to drive the product to descend synchronously, downward movement of the product is realized, and the product can be lifted away by the lifting mechanism. Wherein, adopt the setting of bearing, the push pedal is at the in-process that moves in the front and back, and the bearing then can roll relatively on the push pedal, for rolling friction, can prevent the wearing and tearing of push pedal with regard to the support, improves the smoothness nature and the stability of layer board jacking simultaneously.

Referring to fig. 2, a longitudinal plate 10 is arranged on the machine tool body, the longitudinal plate is arranged on the front side of the hydraulic cylinder, a longitudinal sliding groove 11 is arranged at the top of the longitudinal plate, and the bottom of the push plate is arranged in the longitudinal sliding groove in a sliding manner. Through the setting of vertical board and vertical spout, can carry on spacingly to the removal of push pedal, prevent the push pedal skew, also prevent the push pedal skew and cause the pneumatic cylinder output shaft to warp, reduce the maintenance rate, guarantee the life of pneumatic cylinder.
