Description

Technical Field

[0001] The utility model belongs to the field of workpiece correction, and in particular relates to a correction and holding device for a U-shaped bolt. Background Art

[0002] U-bolts are non-standard fasteners named for their U-shaped shape. They have threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as car leaf springs. Figure 1 The right-angle U-shaped bolt comprises two parallel rods with threads at the ends. During the tapping process, the U-shaped bolt is often easily deformed due to machining stress, so that the two rods cannot remain parallel. Before the invention, our company usually performs manual correction after the right-angle U-shaped bolt is processed, which is time-consuming and laborious. Utility Model Content

[0003] Based on the content in the background technology, the present application provides a U-bolt correction and retention device, including a base plate, two adjustment fixing plates, two pressure plates, four locking bolts and four locking nuts, one adjustment fixing plate corresponds to one pressure plate, two locking bolts and two locking nuts, and the adjustment fixing plate and the corresponding pressure plates are respectively arranged on the front and back sides of the base plate;

[0004] The substrate is provided with a first long hole, a second long hole and a third long hole in sequence, the first long hole, the second long hole and the third long hole are parallel to each other, the second long hole is located between the first long hole and the third long hole, a slider is fixed to the middle of the adjusting fixing plate, the slider is integrally connected with the adjusting fixing plate, the slider of the adjusting fixing plate passes through the second long hole of the substrate and can slide along the direction of the second long hole, through holes are respectively provided on both sides of the adjusting fixing plate at corresponding positions of the first long hole and the third long hole of the substrate, and through holes are also respectively provided on both sides of the pressing plate at corresponding positions of the first long hole and the third long hole of the substrate;

[0005] The locking bolt passes through the through hole of the corresponding adjustment fixing plate, the first long hole or the third long hole of the base plate, and the through hole of the corresponding pressing plate in sequence, and is then locked by the corresponding locking nut;

[0006] A through hole is provided at the center of the slider of the adjusting and fixing plate, and a flexible bushing is fixedly arranged in the through hole of the slider.

[0007] First, loosen all the locking nuts, and adjust the fixing plate as the slider slides in the second long hole to adjust its position on the base plate. After adjusting the positions of the two adjusting fixing plates according to the U-bolts of different specifications, the two rods of the U-bolt can pass through the flexible bushing at the center of the corresponding slider. Finally, tighten all the locking nuts, and the adjusting fixing plate and the corresponding pressure plate are relatively squeezed to fix the adjusting fixing plate securely. In this way, the two rods of the U-bolt can be kept limited in the horizontal direction. During the tapping and other processing processes, the two rods of the U-bolt can be well supported and can always remain parallel to each other, eliminating the need for subsequent manual correction procedures.

[0008] Furthermore, the pressure plate is provided with a through hole at the slider corresponding to the adjusting fixing plate, and the corresponding slider can also pass through the through hole of the pressure plate, so that when the locking nut is tightened, the movement of the slider in the through hole of the pressure plate is not restricted, thereby avoiding the pressure plate and the corresponding adjusting fixing plate from being unable to be pressed against each other due to the slider contacting the pressure plate.

[0009] Preferably, the flexible bushing is a rubber bushing, which has an interference fit with the rod of the U-bolt. When the rod of the U-bolt passes through the corresponding rubber bushing, the rubber bushing can clamp the rod while avoiding damaging the surface of the rod.

[0010] Furthermore, mounting holes are provided at the four corners of the base plate to facilitate the installation and fixing of the correction and holding device on the processing platform of the U-bolts.

[0011] Through the above technical solution, the utility model at least includes the following beneficial effects:

[0012] The correction and holding device of the U-bolt described in the present application is easy to use and has strong adjustability. Its adjustment fixing plate can adapt to U-bolts of different specifications by adjusting the position. After locking, the two rods of the U-bolt can be held at the upper limit in the horizontal direction. During the processing of tapping and other processing, the two rods of the U-bolt can be well supported and always kept parallel to each other, eliminating the need for subsequent manual correction procedures.
