Abstract

(57) [Abstract] [Purpose] To provide a cross-sectional shape of an aluminum extruded material that allows a polishing shaft to be easily and accurately caulked and fixed to an aluminum extruded material. [Structure] A cross-sectional shape of an aluminum extruded material in which a polishing shaft is fitted and caulked and fixed, wherein a plurality of irregularities are provided on the bottom of the shaft fitting groove.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cross-sectional shape of an aluminum extruded material in which a polishing shaft is caulked and fixed.

[0002]

[Prior art]

 Conventionally, aluminum extruded materials with a polishing shaft caulked and fixed had a flat groove bottom shape.

[0003]

[Problems to be solved by the device]

 In the case of a linear guide mechanism that guides aluminum extruded material in which two polishing shafts are caulked and fixed at a relative position of 180 ° by sandwiching two polishing shafts between multiple guide bearings, the manufacturing dimensional accuracy of the aluminum extruded material However, the accuracy of the distance between the two polishing axes was inferior compared to the cutting process, and the aluminum extruded material linear movement sometimes rattled, or conversely, the bearing was overloaded. The present invention has been made to solve the above problems.

[0004]

[Means for Solving the Problems]

 The present invention is a cross-sectional shape of an aluminum extruded material (3) in which a plurality of irregularities are provided on the bottom (9) of the shaft fitting groove of the aluminum extruded material.

[0005]

[Action]

 Insert the two polishing shafts (2) into the shaft fitting grooves at two 180 ° relative positions of the aluminum extruded material (3), press the pressure from both sides and crimp while keeping the distance between the shafts at the specified dimension (a). Fix it. At this time, the polishing shaft (2) deforms the unevenness of the aluminum extruded material groove bottom portion (9) to accurately realize the specified dimension (a) after the completion of the crimping.

[0006]

【Example】

 An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Insert the two polishing shafts (1) and (2) into the shaft fitting grooves at two 180 ° relative positions of the aluminum extruded material (3) and apply pressure from both sides so that the distance between the shafts becomes the specified dimension (a). After caulking, fix. The aluminum extrusion groove bottom (9) is uneven and plastically deforms with a low pressure of the polishing shaft, so even if the pressure after caulking is released, the specified dimension (a) is maintained and the longitudinal waviness is minimal. . The aluminum extruded material (3) performs a linear motion by being guided by a plurality of guide bearings (5), (6), (7) and (8) having outer peripheral guide grooves arranged in the base plate (4). The center distance between the first guide bearing (5) and the second guide bearing (6) and between the third guide bearing (7) and the fourth guide bearing (8) is constant, and it is fixed by caulking to the aluminum extruded material (3). Since the polishing shafts (1) and (2) have the outer peripheral end distance (a) in the above-described state with no waviness, a smooth linear motion is realized. It should be noted that, instead of increasing the accuracy of the distance between the two polishing axes, it can also be applied to the case of increasing the accuracy of the distance between one polishing axis and the reference plane.

[0007]

[Effect of device]

 The polishing shaft can be easily and accurately caulked and fixed to the extruded aluminum material.
