Abstract

The utility model provides a high shock-resistance bed piece of the machine tool, belonging to a component of the machine tool, which is provided with a bed body, a latticed reinforcing rib plate with round holes is arranged in the bed body, the cavity formed by the bed piece and the reinforcing rib plate is padded with concrete, the concrete padding inside the bed body has sound shock-absorption function, due to the round holes in the reinforcing rib plate, the concrete padding is connected into a whole, thus the natural frequency, rigidity and stability of the bed piece is enhanced to fit for the operating requirements of the precision processing machine tool. Compared with the natural frequency of the welding bed body without concrete padding and that of the bed body made by traditional cast iron material, the natural frequency of the bed body, with simple structure and low manufacturing cost, has been improved.

Description

High shock resistance bed piece

Technical field

The utility model relates to a kind of lathe bed of lathe, especially a kind of lathe bed of precision finishing machine.

Background technology

At present, precision finishing machine (precise numerical control machine) has obtained application more and more widely at home and abroad, and it has improved the machining accuracy of part widely.The lathe bed of lathe is the core component on the lathe, and the quality of its performance, structure, parameter will directly influence precision machined effect.The lathe bed material of precision finishing machine must satisfy the requirement of high rigidity, high-speed, high life and high damping.And traditional lathe bed generally adopts cast iron materials, can not satisfy the instructions for use of modern precision machining tool well.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of high shock resistance bed piece, to adapt to the instructions for use of precision finishing machine.

The utility model is achieved in that high shock resistance bed piece, and it has the lathe bed body, and latticed reinforcement gusset is arranged in the lathe bed body, and strengthening has circular hole on the gusset, in the cavity that forms between lathe bed body and the reinforcement gusset concrete obturator is arranged.

Adopt the high shock resistance bed piece of said structure, the concrete obturator of lathe bed body inside has good shock-absorbing performance, owing to strengthen the existence of the circular hole on the gusset, the concrete obturator connects into an integral body, so both improved the intrinsic frequency of lathe bed itself, improve the rigidity of lathe bed again, strengthened the stability of lathe bed, adapted to the instructions for use of precision finishing machine.Use shows, this bed piece has improved 20%-30% than the intrinsic frequency of the welding lathe bed of fill concrete not, improved 40%-50% than the intrinsic frequency of the lathe bed made from traditional cast iron materials.And lathe bed structure is simple, and manufacturing cost is also lower.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.

As shown in drawings, the high shock resistance bed piece of the utility model, it has lathe bed body 1, and latticed reinforcement gusset 3 is arranged in the lathe bed body, and strengthening has circular hole 4 on the gusset, in the cavity that forms between lathe bed body and the reinforcement gusset concrete obturator 2 is arranged.

The lathe bed body can be welded with the 20# steel plate, and cover plate 1-1 can weld at last.The main effect of latticed reinforcement gusset is the rigidity that improves lathe bed.Strengthen the circular hole on the gusset, cement mortar flows when not only being convenient to make, make cement mortar be full of the whole bed bodily lumen, can also make the concrete obturator that cement mortar is solidified back formation connect into an integral body as shown in Figure 3, thereby improve the rigidity and the stability of concrete itself.

During manufacturing, cement mortar is injected from the bottom of lathe bed body.Because cement mortar has flowability, therefore can be full of the inner chamber of lathe bed body by the circular hole on the reinforcement gusset, solidify the back forms an integral body in the lathe bed body concrete obturator.

Claims

1, high shock resistance bed piece is characterized in that, it has lathe bed body (1), and latticed reinforcement gusset (3) is arranged in the lathe bed body, and strengthening has circular hole (4) on the gusset, in the cavity that forms between lathe bed body and the reinforcement gusset concrete obturator (2) is arranged.
