DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 3 As shown, this embodiment provides an auxiliary device for installing a steering gear housing, comprising:

[0030] Workbench 1;

[0031] A second plate body 4, the second plate body 4 is fixedly mounted on the workbench 1;

[0032] The cylinder 2 is installed on the workbench 1, and the cylinder 2 is connected to the first plate 3. The extension direction of the first plate 3 is consistent with the extension direction of the second plate 4. The cylinder 2 can drive the first plate 3 to approach or move away from the second plate 4;

[0033] A third plate body 9, the third plate body 9 is slidably mounted in the first mounting groove 31 of the first plate body 3, and the third plate body 9 can move along the extension direction of the first plate body 3;

[0034] The first block 5 and the second block 6 are both slidably mounted in the first mounting groove 31, and the first block 5 and the second block 6 are both fitted with the third plate 9, and the first block 5 and the second block 6 can move along the extension direction perpendicular to the first plate 3;

[0035] The fourth plate body 10 is slidably mounted in the second mounting groove 41 of the second plate body 4, and the fourth plate body 10 can move along the extension direction of the second plate body 4;

[0036] The third block 7 and the fourth block 8 are both slidably installed in the second installation groove 41, and the third block 7 and the fourth block 8 are both in contact with the fourth plate 10. The third block 7 and the fourth block 8 can move along the extension direction perpendicular to the second plate 4.

[0037] As a whole, the steering gear housing to be fixed is placed on the workbench 1 and one side of it is abutted against the third block 7 and the fourth block 8 on the second plate 4. The first plate 3 is driven close to the second plate 4 by the cylinder 2. In the process of the first plate 3 approaching the second plate 4, due to the irregular shape of the steering gear housing, the wider part of the steering gear housing in the width direction of the first plate 3 will first contact with the first block 5 / the second block 6. When the part of the steering gear housing first contacts with the first block 5, as the cylinder 2 continues to drive the first plate 3 close to the second plate 4, the reaction force formed by the contact between the first block 5 and the steering gear housing can make the first block 5 move along its extension direction. Due to the movement of the first block 5, the reaction force between the first block 5 and the fitting surface of the third plate 9 is The force formed can make the third plate 9 move along its extension direction, and the force of the third plate 9 on the second block 6 can make the second block 6 move along its extension direction. As the cylinder 2 drives the first plate 3 close to the second plate 4, when the other side of the steering gear housing is partially in contact with the third block 7, the third block 7 moves, and the force formed between the fitting surfaces of the third block 7 and the fourth plate 10 can make the fourth plate 10 move along its extension direction. Then, the force of the fourth plate 10 on the fourth block 8 can make the fourth block 8 move along its extension direction. Since the first block 5, the second block 6, the third block 7 and the fourth block 8 are all in contact with the steering gear housing, the steering gear housing is clamped and fixed while achieving internal balance.

[0038] like Figure 1-Figure 2As shown, in one embodiment, the first block 5, the second block 6 and the third plate 9 are specifically fitted as follows: the first inclined portion on the first block 5 is fitted with the third inclined portion on the third plate 9, and the second inclined portion on the second block 6 is fitted with the fourth inclined portion on the third plate 9;

[0039] The third block 7 , the fourth block 8 and the fourth plate 10 are fitted together specifically as follows: the fifth inclined portion on the third block 7 fits with the sixth inclined portion on the fourth plate 10 , and the seventh inclined portion on the fourth block 8 fits with the eighth inclined portion on the fourth plate 10 .

[0040] Specifically, the first inclined portion is adapted to fit with the third inclined portion, and the second inclined portion is adapted to fit with the fourth inclined portion. When the first block 5 contacts the steering gear housing, the force generated by the movement of the first block 5 along its extension direction can cause the third plate 9 to move along its extension direction, and then the force of the third plate 9 on the second block 6 can cause the second block 6 to move along its extension direction, so that the first block 5 and the second block 6 are both in contact with the steering gear housing. Similarly, under the driving action of the cylinder 2, the third block 7 and the fourth block 8 can also contact with the steering gear housing, thereby finally achieving force balance and completing the clamping and fixation of the steering gear housing.

[0041] like Figure 2-Figure 3 As shown, in one embodiment, the inner wall of the first installation groove 31 is installed with a first column 32, a second column 33 and a third column 34, the first block 5 is provided with a first vertical groove 51 adapted to the first column 32 in its moving direction, the second block 6 is provided with a second vertical groove adapted to the second column 33 in its moving direction, and the third plate 9 is provided with a first transverse groove 91 adapted to the third column 34 in its extending direction;

[0042] The fourth column 42, the fifth column 43 and the sixth column 44 are installed on the inner wall of the second installation groove 41, the third block 7 has a third vertical groove adapted to the fourth column 42 in its moving direction, the fourth block 8 has a fourth vertical groove adapted to the fifth column 43 in its moving direction, and the fourth plate 10 has a second transverse groove adapted to the sixth column 44 in its extending direction.

The fourth column 42 is adapted to the third vertical groove, the fifth column 43 is adapted to the fourth vertical groove, and the sixth column 44 is adapted to the second transverse groove. The stability of the third block 7, the fourth block 8 and the fourth plate 10 during the movement can be improved, thereby improving the stability of the entire device during the clamping process.

[0047] Specifically, two groups of first elastic members 11 are provided and are symmetrically arranged about the third plate body 9, and two groups of second elastic members 12 are also provided and are symmetrically arranged about the fourth plate body 10. By arranging the first elastic members 11 and the second elastic members 12 symmetrically, it is possible to ensure that the forces on the third plate body 9 and the fourth plate body 10 are more balanced, thereby improving the stability of the third plate body 9 and the fourth plate body 10 during the sliding process.

[0048] like Figure 1-Figure 2 As shown, in one embodiment, the ends of the first block 5 and the second block 6 away from the third plate 9 are arc-shaped, and the ends of the third block 7 and the fourth block 8 away from the fourth plate 10 are arc-shaped.

[0049] Specifically, the contact ends of the first block 5, the second block 6, the third block 7 and the fourth block 8 with the steering gear housing are arc-shaped, which can reduce the concentration of stress at the contact ends and improve the bearing capacity of the contact ends of the first block 5, the second block 6, the third block 7 and the fourth block 8.
