DETAILED DESCRIPTION

[0031] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] With reference to Figure 1 The utility model provides an embodiment: a kind of automobile U bolt correction frock, the upper surface of pedestal 1 is fixedly connected with fixed plate 2 in front and back two sides, the upper surface of pedestal 1 is fixedly connected with electric push rod 3 in left and right two sides, the length of electric push rod 3 of two sides from the center of pedestal 1 is consistent, the end of electric push rod 3 close to the center of pedestal 1 is fixedly connected with correction plate 4, when electric push rod 3 is started, it can drive correction plate 4 to move linearly in left and right directions, when the correction plate 4 of two sides is synchronously close to each other, it can be clamped and corrected to the U bolt placed in the center, the outer wall surface of correction plate 4 is fixedly connected with heat insulation casing 8, heat insulation casing 8 can isolate the heat generated in correction plate 4, to avoid staff from being scalded when contacting correction plate 4.

[0033] With reference to Figure 2 - Figure 4 The side surface of correction plate 4 close to the center of pedestal 1 is provided with correction groove 5, the number of correction groove 5 is several, several correction grooves 5 are linearly arrayed on the surface of correction plate 4, so that frock can simultaneously correct multiple U bolts, correction groove 5 is composed of adjusting groove 51 and shaping groove 52, adjusting groove 51 is provided on the side surface of correction plate 4 close to the center of pedestal 1, adjusting groove 51 is provided in trapezoidal table structure as a whole, the side surface area of adjusting groove 51 close to the center of pedestal 1 is greater than the side surface area away from pedestal 1, so that the inner wall surface of the front side of adjusting groove 51 is provided in inclined structure, shaping groove 52 is provided on the side of adjusting groove 51 close to the center of pedestal 1, heating casing 6 is fixedly connected in correction groove 5, electric heating wire is provided in the inner wall of heating casing 6, heat can be generated after electric heating wire is electrified to heat the end of U bolt placed into heating casing 6, the size of heating casing 6 and the size of correction groove 5 are mutually adapted, the upper surface of heating casing 6 is provided in open state structure, the size and shape of heating casing 6 in adjusting groove 51 are mutually adapted with the end of U bolt, the size of heating casing 6 in shaping groove 52 is greater than the end size of U bolt.

[0034] When the U-shaped bolt is corrected, the two ends of the U-shaped bolt are inserted into the two heating housings 6 on the left and right sides, and then the heating housings 6 can be powered to heat the ends of the U-shaped bolt, thereby reducing the yield strength of the U-shaped bolt and making the U-shaped bolt more easily deformed plastically, so that it is easier to correct. Then the electric push rod 3 can be started to drive the two correction plates 4 on both sides to move away from each other, thereby pulling the ends of the U-shaped bolt to deform the ends of the U-shaped bolt away from the center of the U-shaped bolt. Then the electric push rod 3 is started again to drive the two correction plates 4 on both sides to move towards each other, thereby correcting the ends of the U-shaped bolt. At this time, the inclined surface inside the heating housing 6 will extrude and adjust the deformed ends of the U-shaped bolt, so that the ends of the U-shaped bolt are quickly corrected to a vertical state. The ends of the U-shaped bolt will enter the part of the heating housing 6 located in the adjusting groove 51 along the inclined surface of the heating housing 6 to be shaped. The ends of the U-shaped bolt can be corrected and adjusted when deformed in any direction.

[0035] The gap between the two fixed plates 2 fixedly connected to the upper surface of the base 1 is fixedly connected with a hanging rod 7. The upper side of the hanging rod 7 is provided with a limiting unit, which includes an arc-shaped limiting groove 71. The size of the arc-shaped limiting groove 71 is matched with the size of the U-shaped bolt. The U-shaped bolt can be hung in the arc-shaped limiting groove 71 for preliminary limiting. When the correction plate 4 moves for correction, the hanging rod 7 will apply a reaction force from the inside of the U-shaped bolt to the outside, further correcting the U-shaped bolt. The arc-shaped limiting groove 71 is opened on the upper side of the hanging rod 7. The surface positions of the outer wall of the hanging rod 7 located on the front and back sides of the arc-shaped limiting groove 71 are fixedly connected with limiting plates 72. The limiting plates 72 can further limit the front and back sides of the U-shaped bolt placed in the arc-shaped limiting groove 71, improving the stability of the U-shaped bolt during correction.

[0036] Referring to Figure 4 - Figure 5 A groove 9 is opened on the upper surface of the hanging rod 7. The front and back ends of the groove 9 penetrate the fixed plates 2. A straight rod 10 is arranged in the groove 9. When the straight rod 10 is placed in the groove 9, it will completely enter the inside of the hanging rod 7, without hindering the placement and correction of the U-shaped bolt. Anti-skid lines 12 are opened on the outer wall surfaces of the front and back ends of the straight rod 10. Circular plates 11 are fixedly connected to the front and back sides of the straight rod 10. The circular plates 11 are in close contact with the fixed plates 2. The circular plates 11 can limit the straight rod 10, so that the straight rod 10 can be stably placed in the groove 9, avoiding disengagement to the front and back sides. The anti-skid lines 12 can increase the friction between the hands of the workers and the straight rod 10, avoiding slipping. After the correction of multiple U-shaped bolts, the straight rod 10 can be pulled up to take out multiple heated U-shaped bolts at the same time, avoiding the risk of burns caused by direct contact with the heated U-shaped bolts, and improving the disassembly efficiency of the U-shaped bolts.

[0037] Working principle: the U-shaped bolt is hung inside the arc-shaped limiting groove 71 for preliminary limiting, and the end of the U-shaped bolt is inserted into the two heating shells 6 on the left and right sides, then the heating shell 6 is powered on to heat the end of the U-shaped bolt, the yield strength of the U-shaped bolt is reduced, then the electric push rod 3 is started to drive the two sides of the correction plate 4 to move away from each other, the end of the U-shaped bolt is pulled away from the center of the U-shaped bolt, then the electric push rod 3 is started to drive the two sides of the correction plate 4 to move towards each other, the end of the U-shaped bolt is corrected, the end of the U-shaped bolt moves and corrects inside the heating shell 6, the inclined surface inside the heating shell 6 first extrudes and corrects the deformed end of the U-shaped bolt, then the end of the U-shaped bolt enters the part of the heating shell 6 in the adjusting groove 51 for shaping, the end of the U-shaped bolt can be corrected and adjusted when it deforms in any direction, after correction and shaping, the straight rod 10 is pulled up to take down multiple heated U-shaped bolts synchronously, the operation is simple.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
