DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, as Figure 1-6As shown, the utility model provides a technical solution: a clamping tool for the left suspension assembly of an engine, comprising a lower plate 1, a positioning rail 5 and a long bracket 6, the top of the lower plate 1 is equipped with a positioning rail 5, and a positioning block 7 is arranged above the positioning rail 5, bracket fixing seats 4 are installed on both sides of the top of the lower plate 1, and the inside of the bracket fixing seat 4 is provided with a long bracket 6, and the inside of the long bracket 6 is provided with a weight reduction groove 9, the top of the lower plate 1 is equipped with a guide column 2, and the top of the guide column 2 is equipped with an upper plate 3, and the top of the upper plate 3 is provided with a connector 16. The output of the connector 16 A pressure head 17 is installed at the end, a through hole 10 is opened at the front end of the bracket fixing seat 4, and the positioning screw is threadedly connected to the through hole 10, and a positioning screw penetrating the weight reduction groove 9 is arranged inside the through hole 10, and a bracket 8 is arranged at the top of the lower plate 1, and an irregular surface holding mechanism for quickly positioning the position of the bracket 8 is installed on one side of the positioning block 7, and the irregular surface holding mechanism includes a movable groove 12 and an arc-shaped elastic plate 13, and a movable groove 12 is opened inside the positioning block 7, and a positioning pin 11 penetrating the positioning block 7 is arranged on one side of the movable groove 12, and an arc-shaped elastic plate 13 is arranged inside the movable groove 12. The elastic plate 13 is provided with an air bag 14 inside the arc-shaped elastic plate 13. The outer wall of the positioning pin 11 is provided with a reset spring 15, and one end of the reset spring 15 is in contact with the inner wall of the positioning pin 11. A left suspended main spring 18 is provided above the bracket 8. By passing the long bracket 6 through the bracket fixing seat 4 and in contact with the rear wall of the positioning block 7, the positioning block 7 drives the positioning pin 11 to insert the pressure head 17 to quickly position it. At this time, the starting connector 16 drives the pressure head 17 to press downward, descend at a uniform speed, and bend the product. The product is bent, and the pressure head 17 continues to move downward. Lowering and compacting the product, this structure is convenient for quickly processing and fixing the left suspension main spring 18, and the locating pin 11 is inserted into the hole of the left suspension main spring 18. Since the holes are of different depths, the locating pin 11 can be squeezed toward the position of the arc-shaped elastic plate 13, so that the position of the return spring 15 and the air bag 14 undergo elastic deformation. Since the return spring 15, the arc-shaped elastic plate 13 and the air bag 14 are all elastic elements, the locating pin 11 is driven by its own elastic force to fit and fix with the hole of the left suspension main spring 18, thereby increasing stability and being suitable for locating holes of different depths.

[0022] Working principle: First, turn on the external power supply, place the left suspension main spring 18 above the bracket 8, and place the main spring at the left suspension main spring 18. At this time, push the positioning block 7 to move on the positioning guide rail 5, and the positioning block 7 drives the positioning pin 11 to insert into the hole at the left suspension main spring 18. The positioning pin 11 is inserted into the hole at the left suspension main spring 18. Due to the different depths of the holes, the positioning pin 11 can be squeezed toward the arc elastic plate 13, so that the position of the return spring 15 airbag 14 is elastically deformed. Since the return spring 15, the arc-shaped elastic plate 13 and the airbag 14 are all elastic elements, they drive the locating pin 11 to fit and fix with the position hole of the left suspension main spring 18 under the action of their own elastic force, so as to increase the stability and be suitable for locating holes of different depths. At this time, the starting connector 16 drives the pressure head 17 to press downward and descend at a uniform speed to bend the product. When the product is bent, the pressure head 17 continues to descend to press the product. This structure facilitates the rapid processing and fixation of the left suspension main spring 18.

[0023] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
