Oil-seal press-mounting clamp and using method thereof

Abstract

The invention relates to an oil-seal press-mounting clamp and a using method thereof. The clamp comprises a vertical outer ring which can be connected to an oil-seal edge of a bearing cap in a sleeving manner, and an inner pressing sleeve which is used for sealing and pressing to-be-pressed oil seal into the oil seal hole in the bearing cap, wherein the inner pressing sleeve is coaxially arranged in the outer ring and can slide up and down along the axial direction of the outer ring; opposite round holes are formed in the side wall of the outer ring, a cylindrical pin penetrates the round holes, and a strip-shaped key groove which can be penetrated by the cylindrical pin is formed in the inner pressing sleeve. According to the oil-seal press-mounting clamp, due to the outer ring and the inner pressing sleeve, the outer ring is connected to the oil-seal edge of the bearing cap in a sleeving manner to complete primary positioning, and the inner pressing sleeve and the outer ring are positioned by adopting the cylindrical pin, so that the inner pressing sleeve and the outer ring are always kept to be concentric and can only make relative movement along the axial direction, the oil seal is pressed in the direction concentric to the oil-seal edge when being pressed in, and vertical press mounting of the oil seal is guaranteed; the uniformity of tools for oil-seal pressing can be realized since positioning is performed at the side of the oil-seal edge of the bearing cap.

Description

【Technical field】 [0001] The invention relates to the field of clamps, in particular to an oil seal press-fitting clamp and a use method thereof. 【Background technique】 [0002] Traditional oil seal press-fit requires a special press-fit base. like figure 1 As shown, the press-fit base is designed with a positioning mandrel 6. When press-fitting the oil seal, the pressure sleeve 7 is set on the positioning mandrel 6. The base boss of the press-fit base fixes the bottom of the bearing cover 9, and the oil seal 8 is put into the The upper end of the bearing cover 9 and the bottom of the pressure sleeve 7 are in contact with the oil seal 8, and the press is started. The positioning mandrel 6 protruding from the base cooperates with the pressure sleeve 7 to press into the oil seal, that is, the pressure sleeve 7 moves down along the positioning mandrel 6, and the oil seal 8 Press into the bearing cover 9. However, due to the wide variety of PTO bearing caps, the oil seal seal...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the existence of a variety of press-fit bases, the accumulation on site is serious and wastes space;

[0006] 2. When changing production of different types of products, it is necessary to find the corresponding press-fit base and replace it, which is time-consuming and affects production efficiency
