Embodiment 1

[0021] Such as figure 1 As shown, it is a schematic diagram of the repair size of the cross slider of the present invention, and the method for repairing the cross slider of the vacuum pump is specifically:

[0022] 1) Grind and trim the worn slideway 1 until smooth, use a measuring ruler to measure the thickness of the polished slideway 1 to 13mm, and then measure the thickness of the unworn slideway to 14.6mm to obtain the thickness of the worn surface of the slideway, is 1.6mm.

[0023] 2) Grind and trim the worn cross slider 2 until smooth, use a measuring ruler to measure the thickness of the polished cross slider 2 to 15cm, and then measure the thickness of the unworn cross slider 2 to be 15.3cm, and obtain the wear of the slideway The thickness of the surface is 3mm.

[0024] 3) Repair the worn cross slider 2, increase the thickness of the corresponding working surface of the cross slider, and the increased thickness is 1.6+3=4.6mm. That is to say, the total thicknes...

Embodiment 2

[0027] A method for repairing the cross slide of a vacuum pump, specifically:

[0028] 1) Grind the worn slideway until it is smooth, use a measuring ruler to measure the thickness of the polished slideway to 12.6mm, and then measure the thickness of the unworn slideway to 14.6mm to obtain the thickness of the worn surface of the slideway, which is 2mm.

[0029] 2) Grind and trim the worn cross slider until smooth, use a measuring ruler to measure the thickness of the polished cross slider to 14.9cm, and then measure the thickness of the unworn cross slider to 15.3cm to obtain the wear surface of the slideway The thickness is 4mm.

[0030] 3) Repair the worn cross slider, increase the thickness of the corresponding working surface of the cross slider, and the increased thickness is 2+4=6mm.

[0031] To increase the thickness of the corresponding working surface of the cross slider is to weld a fitting fastener on the corresponding working surface of the cross slider. The thi...

Abstract

The invention discloses a method for repairing a vacuum pump cross-shaped sliding block, and relates to the technical field of slide way sliding block repairing in a vacuum pump. The problem that equipment degradation cannot be eliminated by replacing a worn sliding block is solved. The method comprises specifically the following steps that a worn slide way is measured, and the thickness of a wornsurface of the slide way is measured as d; a worn cross-shaped slide block is measured, and the thickness of a worn surface of the cross-shaped slide block is measured as d'; the worn cross-shaped sliding block is repaired, the thickness of the corresponding working surface of the cross-shaped sliding block is increased, and the increased thickness is d+d'. According to the method, the wearing amount generated by the slide way which is not easy to replace is added to the corresponding working surface of the cross-shaped slide block, so that losses of the slide way are compensated indirectly,the purpose of meeting the design requirement on a working clearance between the cross-shaped sliding block and the slide way is achieved, and a lot of cost is saved.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a vacuum pump with a structure of a cross slide and a slideway, in particular to a method for repairing a cross slide of a vacuum pump. Background technique [0002] There are many types of equipment using cross sliders and slideways, basically vertical and horizontal. For vertical vacuum pumps, the slideways are designed to be cast steel (higher hardness). The working surface is made of black gold material (low hardness, easy to replace). In order to ensure processing accuracy and convenient casting, generally, the slideway and the body are cast as an integral structure. After a period of operation, no matter what the reason is, the gap between the cross slider and the slideway will increase, jumping occurs during operation, and noise will be generated. If it is not dealt with in time, the trend of equipment deterioration will be more obvious , until scrapped. The increas...
