Linear rail fixing frame for isothermal normalizing stage of linear guide rails

Abstract

The invention discloses a linear rail fixing frame for an isothermal normalizing stage of linear guide rails. The linear rail fixing frame can be used for heating, heat preservation and cooling for normalizing of the batched linear guide rails. According to the linear rail fixing frame, a guide rail sliding block at the bottom of the rail fixing frame can slide on a ground guide rail in a hearth in a matched mode, linear rail fixing channels on the rail fixing frame and linear guide rail clamping pieces on the linear rail fixing channels are used in the rail fixing frame so as to suspend the linear guide rails in an array mode, and then the batched linear guide rails can be regularly and orderly on the whole. When the linear rail fixing frame is used for operation of heating and heat preservation in isothermal normalizing, the arranged linear guide rails together with the linear rail fixing frame are directly pushed into a heating furnace and fixed; and when cooling is carried out, ifoil quenching needs to be carried out, an ear plate at the top of the rail fixing frame is used for suspending the linear rail fixing frame on which the linear guide rails are suspended into an oil quenching tank.

Description

technical field [0001] The invention relates to a linear track fixing frame used in the isothermal normalizing stage of a linear guide rail. Background technique [0002] Linear guide rails, also known as line rails, slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion applications, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Linear bearings are mainly used in automated machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear bearings and linear axes are used together. Linear guides are mainly used in mechanical structures with high precision requirements. There is no intermediate medium between the moving elements and f...

Problems solved by technology

[0006] If the working time is too long, the steel balls will start to wear, and the preload on the steel balls will start to weaken, resulting in a reduction in the movement accuracy of the working parts of the machine tool

If you want to maintain the original accuracy, you must replace the guide rail bracket, or even replace the guide rail
