Abstract

PURPOSE:To impart any desired pressure to a rolling body which bears the load, and to provide adjustability for the imparted pressure, by furnishing a tapered gib between slide tables and a mount table to be installed at the oversurface of said slide tables. CONSTITUTION:A pair of track tables 2 are mounted on the mounting reference surface 7 of a bed 1 using bolts 8. On these track tables 2 two pairs of slide tables 3 make straight reciprocation under guidance, circulating along a pair of endless tracks 9 formed at each slide table 3, wherein a number of balls 4 are bearing the load between the track tables 2 and slide tables 3. A mount table 5 is installed at the oversurfaces of the slide tables 3 and fixed by bolts 10a, 10b oriented in the width direction of the slide tables 3, and a tapered gib 6 is interposed between the slide tables 3 and mount table 5. This tapered gib 6 is advanced and retracted in the direction of bolts within a certain range determined by long holes 11a, 11b formed in the tapered gib 6, by loosening the bolts 10a, 10b.

This invention relates to a linear sliding table assembly that is frequently used in the sliding parts of general industrial machines such as industrial robots.

のであることが要請される。Generally, a linear sliding table used in such a sliding part is required to be able to be assembled with high precision, to have good positioning and repeatability, and to have a long life.

くする原因になるほか。However, if there is wobbling in the rolling elements such as balls or rollers that are built into a linear sliding table and have a negative weight between the track and the sliding table, the inertia will increase when the direction of reciprocating movement changes. The hammer action and prying load caused by the moment 42 will instantaneously apply an impact load several times higher, which will shorten the life of the product.

向上を図ることが行なわれている。Therefore, in this type of linear sliding table, in order to eliminate the above-mentioned wobbling, the rolling elements (2 pressurized) are applied to increase the contact rate of all rolling elements, thereby improving the load capacity and life. things are being done.

。This is because the table is equipped with a bearing structure in which pressurization is applied to the rolling elements that apply the load between the slide table and the track base by giving the slide table a rotational twist. The same is true for assemblies. 5 The present inventor previously proposed a method of interposing a shim between the sliding base and the mounting base and a method of making the upper surface of the sliding base a tapered surface as a means of applying pressurization.

ない。However, with the method of inserting shims between the sliding base and the mounting base, it is not necessary to increase or decrease the number of shims installed in order to adjust the target pressurization, and it is necessary to repeatedly insert the shims each time. Adjusting the pressurization is extremely complicated because the moving base and the mounting base must be assembled, and furthermore, there is the problem that the pressurization cannot be adjusted after being assembled into the device unless it is disassembled. there were. In addition, with the method of making the top surface of the slide table a tapered surface, it is necessary to perform a complicated taper process on the top surface of the slide table, which increases the cost. This limits the versatility of the bearing structure, and furthermore, the pressurization cannot be adjusted after it is installed in a device.

。In view of this, the present invention includes a tapered gib interposed between a sliding table and a mounting base attached to the upper surface of the sliding table,
Utilizing the difference in wall thickness between the proximal end and the distal end of the taper gib, a rotational twist is given to the sliding base when the sliding base and the mounting base are connected with a fastening bolt, This allows pressurization to be applied to rolling elements such as balls and rollers that apply a load between the slide table and the way, and the tapered gib can be moved forward and backward along the width direction (two directions) of the top surface of the slide table. The present invention provides a linear sliding table assembly in which the magnitude of pressurization can be easily adjusted.

便利である。As described above, according to the present invention, the taper gib interposed between the sliding base and the mounting base allows the slide between the track base and the mounting base to be adjusted according to the difference in wall thickness between the base end side and the distal end side of the taper gib. Desired pressurization can be applied to rolling elements such as balls and rollers that carry loads between them and the table, and the pressurization can also be adjusted by moving this taper gib forward and backward. . Moreover, the above-mentioned pressurization can be easily adjusted by simply loosening each bolt that fastens between the sliding base and the mounting base after the assembly of the table assembly is completed. This is extremely convenient as it can also be used in cases where pressurization adjustment is required.
