[0015] Preferably, a plurality of second mounting holes are formed on the outer circular ring, and the connecting bolts cooperate with the second mounting holes.

[0016] Preferably, the metal sealing ring is formed with a plurality of first mounting holes that can be matched with connecting bolts, and the connecting bolts are fixed with nuts after passing through the first mounting holes and the second mounting holes.

[0017] In the above structure, the size of the outer ring is the same as that of the metal sealing ring, the position of the second mounting hole thereon is the same as that of the first mounting hole on the metal sealing ring, and the second mounting hole is a plain hole, which is convenient for fixing the metal sealing ring. The connecting bolt is composed of a large head end and a small head end, both of which have threads, the large head end cooperates with the first mounting hole on the metal sealing ring, and the small head end cooperates with the second mounting hole on the outer ring.

[0018] The present invention also provides a method for installing a steering gear metal sealing ring, comprising the following steps:

[0019] Step 1: Screw one end of the connecting bolt into the first mounting hole of the metal sealing ring. Note that the connecting bolt should be installed on the side of the metal sealing ring without a gap.

[0020] Step 2: Screw the other end of the connecting bolt into the second mounting hole of the mounting tool and fix it with a nut, and fix the metal sealing ring and the mounting tool into a whole through the connecting bolt;

[0021] Step 3: Lay the steering gear cylinder cover flat with the side to be installed with the metal sealing ring facing upwards, and insert the locating pin of the installation workpiece into the third installation hole on the steering gear cylinder cover;

[0022] Step 4: Use a rubber hammer to knock the center circle of the installation workpiece and install the metal sealing ring into the cylinder head.

[0023] In the second step, the positioning pin is located on the extension line of the center line of the metal sealing ring notch, and the positioning pin is installed toward one side of the metal sealing ring;

[0024] In the fifth step, during the installation of the metal sealing ring, a plane meter is placed on the center circle, and the plane meter is used to detect the tilt of the center circle. According to the tilt, a rubber hammer is used to knock the corresponding point on the inner ring to ensure that the center circle and the metal sealing ring are in a horizontal state, thereby preventing the metal sealing ring from tilting. Then the center circle is knocked until the metal sealing ring is installed.

[0025] The invention has the advantages of clever design and convenient operation, and can ensure that the boss in the cylinder head and the notch on the metal sealing ring match at one time. When the gap between the cylinder head and the metal sealing ring is very small, the metal sealing ring can be quickly installed. BRIEF DESCRIPTION OF THE DRAWINGS

The inner ring 102 is arranged between the center circle 101 and the outer ring 103. The cross plate 105 is connected to the inner ring 102 as a whole. The center circle 101 is connected to the cross plate 105 as a whole. The cross plate 105 is also connected to the outer ring 103 as a whole. Positioning pins 106 are respectively arranged at two opposite ends of the cross plate 105, that is, the cross plate 105 is composed of a long plate and a short plate, and the positioning pins 106 are respectively welded at the two ends of the long plate. The position and size of the positioning pins 106 are the same as the third mounting hole 401 on the steering gear cylinder cover 4. The positioning pins 106 can cooperate with the third mounting hole 401 arranged on the steering gear cylinder cover 4 to play a positioning role. The outer ring 103 is connected to the metal sealing ring 5 by connecting bolts 2 and nuts 3. Four second mounting holes 104 are formed on the outer ring 103, and the connecting bolts 2 match the second mounting holes 104. The metal sealing ring 5 is formed with four first mounting holes 501 that can match the connecting bolts 2. The size of the outer ring 103 is the same as that of the metal sealing ring 5. The positions of the four second mounting holes 104 thereon are the same as the positions of the four first mounting holes 501 on the metal sealing ring 5, but the second mounting holes 104 are light holes, which is convenient for fixing the metal sealing ring 5. The connecting bolt 2 is fixed by nuts 3 after passing through the first mounting holes 501 and the second mounting holes 104. The connecting bolt 2 consists of a large head end and a small head end, both of which have external threads. The large head end matches the first mounting hole 501 on the metal sealing ring 5, and the small head end matches the second mounting hole 104 on the outer ring 103.

[0043] In addition, the center circle 101 is a plane, which can be tapped or placed on a plane meter during installation. The inner ring 102 is a plane ring, and the corresponding point on the ring can be tapped according to the plane meter to determine the direction in which the plane is tilted during installation. The center circle 101 and the inner circle 102 are in the same plane, and a plane meter can be placed on the center circle 101.

[0044] A method for installing a steering gear metal sealing ring comprises the following steps:

[0045] Step 1: Screw the large ends of the four connecting bolts 2 into the first mounting holes 501 of the metal sealing ring 5. Note that the connecting bolts 2 are installed on the side of the metal sealing ring 5 without the notch 502.

[0046] Step 2: Screw the small end of the connecting bolt 2 into the second mounting hole 104 of the mounting fixture 1 and fix it with the nut 3, and fix the metal sealing ring 5 and the mounting fixture 1 into a whole through the connecting bolt 2; the positioning pin 106 is located on the extension line of the center line of the notch of the metal sealing ring, and the positioning pin 106 is installed toward one side of the metal sealing ring 5;

[0047] Step 3: Lay the steering gear cylinder cover 4 flat, with the side to be installed with the metal sealing ring 5 facing upwards, and insert the positioning pin 106 of the installation workpiece 1 into the third installation hole 401 on the distribution circle of the cylinder cover 4;

[0048] Step 4: Use a rubber hammer to gently tap the center circle 101 of the installation workpiece 1 to install the metal sealing ring 5 into the cylinder head 4. During the installation of the metal sealing ring 5, place a plane meter on the center circle 101, use the plane meter to detect the plane inclination of the center circle 101, and use a rubber hammer to tap the corresponding point on the inner ring 102 according to the inclination to ensure that the center circle 101 and the metal sealing ring 5 are in a horizontal state, thereby preventing the metal sealing ring 5 from tilting. Then tap the center circle 101 until the metal sealing ring 5 is installed.

[0049] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
