Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to an auxiliary material supporting frame. Background Art

[0002] The contact part between the center support and the crankshaft usually consists of an intermediate support and two symmetrically distributed oblique supports on both sides. They are controlled by hydraulic and mechanical systems, of which the hydraulic system is mainly used for rapid adjustment of the support. The mechanical system is mainly composed of a gear set, where the helical gear drives the spur gear, and then drives the screw to move the cylindrical support up and down. This part is used for fine-tuning the support during processing to ensure the coaxiality of the workpiece and meet the radial runout requirements. It is often used for processing slender shaft parts.

[0003] Currently, when processing slender shaft parts directly through the center bracket, an overhang area is generated under the workpiece, resulting in poor coaxiality, deformation or unqualified size of the product after processing, and the position is slow to find when placing the workpiece. If the product is placed off-center, the center is easy to damage the product surface. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art described above, the utility model provides a solution to the problems of machining deformation of slender shaft parts and rapid placement of workpieces.

[0007] A supporting mechanism is provided below the workpiece and is slidably installed in the T-shaped slide groove, and the supporting mechanism is used to support the suspended part of the workpiece.

[0008] Preferably, the supporting mechanism includes a connecting block, a supporting arm and a supporting platform, a T-shaped slider is fixed at the bottom of the connecting block and cooperates with the T-shaped slide groove, a mounting block is fixed above the T-shaped slider, a through hole is penetrated through the surface of the mounting block, support arms are rotatably connected to both sides of the mounting block, countersunk grooves are symmetrically penetrated through the surface of the support arm, one end of the support arm is rotatably connected to a bridging block, and a support platform is fixed above the bridging block to support the suspended part of the workpiece.

[0009] In the above scheme, the support arms are rotatably connected to the two sides of the mounting block, and the rotatably connected support arms can be easily adjusted in angle, so that the support table is perpendicular to the workpiece surface, providing a good support effect, preventing the product from being deformed or sized unqualified after processing, and maintaining the concentricity during the processing. At the same time, the angle adjustment of the support arms can adapt to workpieces of different sizes, and the overall support mechanism is assembled in a detachable manner. Compared with the center frame, this structure is more compact and light, and easy to install. At the same time, it is also convenient for loading and unloading of products, greatly saving the preparation time before processing.

The angle of the support arm is fixed by tightening the bolts, and the angle adjustment of the support arm can be facilitated by loosening the bolts.

[0011] Preferably, the workpiece is circular or polygonal. A fitting groove adapted to the shape of the workpiece is provided above the support platform.

[0012] In the above scheme, when the workpiece is clamped by the clamping arm, no matter the workpiece is circular or polygonal, the fitting groove on the installed support table is adapted to match the workpiece, and can provide a more fitting shape and produce a stable supporting effect.

[0013] Preferably, the connection mode of the bridge block is the same as the connection mode of the mounting block and the support arm. The bridge block is kept perpendicular to the machine tool.

[0014] In the above scheme, the bridging block is detachable and installed with the support arm, which can facilitate the replacement of different support tables to adapt to different workpieces. The bridging block remains perpendicular to the machine tool, which is beneficial for the support table to support the workpiece below, further improving the stability of the overall support.

[0016] 1. A suspended area is created under the workpiece clamped by the clamping arm. Under the action of the supporting mechanism, the workpiece is supported in the middle and is not suspended, which prevents the product from being deformed or having unqualified dimensions after processing and maintains the concentricity during processing.

[0017] 2. The overall support mechanism is assembled in a detachable manner. Compared with the center frame, this structure is more compact and lightweight, easy to install. It also facilitates the loading and unloading of products and greatly saves the preparation time before processing. BRIEF DESCRIPTION OF THE DRAWINGS
