DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0020] See attached Figure 1 As shown, in this embodiment, a car trunk bend correction device includes a frame 1 and a bottom plate 2 installed on the frame 1, characterized in that it also includes two fixing fixtures 3 installed on the frame 1 for fixing the bend 6, a correction mechanism 5 for pressing the bend 6, and a detection mechanism 4 for detecting the correction degree of the bend 6, the detection mechanism 4 includes a measuring member 41 for detecting the correction degree of the bend 6, a sliding member 44 and a fixing seat 42, wherein a measuring port 41a for detecting the correction degree of the bend 6 is formed on the measuring member 41, and a guide slide 43 is formed on the fixing seat 42; the measuring member 41 is bolted to the sliding member 44, and the measuring member 41 is slidably connected to the fixing seat 42 along the guide slide 43 through the sliding member 44. For details, see the attached Figure 5 As shown, when both ends of the bent pipe 6 are installed on the fixing fixture 3 and are corrected by the correction mechanism 5, the sliding member 44 moves the measuring member 41 to the bent pipe 6 along the guide slide 43 on the fixing seat 42, and detects whether the bent pipe 6 can reach the measuring port 41a of the measuring member 41, thereby judging whether the bent pipe 6 meets the set range value after correction. If the bent pipe 6 can extend into the measuring port 41a, the correction is successful and the bent pipe 6 can be sent to the next process; otherwise, the bent pipe 6 is corrected again according to the actual deformation degree; in addition, the measuring range of the above-mentioned measuring port 41a is the standard value of the bent pipe 6 and its positive and negative tolerance value.

[0021] In this embodiment, see the attached Figure 1 As shown, a plurality of fixing holes 21 for bolting the above-mentioned mechanisms are formed on the bottom plate 2. According to actual production requirements, the fixing holes 21 are provided on the bottom plate 2 to fix the above-mentioned mechanisms accordingly, thereby ensuring the normal operation of the production and inspection of the bent pipe 6.

[0022] In this embodiment, see the attached Figure 4 As shown, the fixing fixture 3 includes a fixture body 31, a pressing block 32 for cooperating with the fixture body 31 to clamp the bent pipe 6, a guide 34 for positioning the end of the bent pipe 6, and at least one, preferably two, cylinders 33 for driving the pressing block 32 to clamp the bent pipe 6. For details, see the attached Figure 6As shown in the figure (a is a horizontal line, b is an angle of the inclined surface of the clamping block 32), one side of the clamping block 32 is provided with an inclined surface structure, wherein the angle between the inclined surface and the horizontal line a is preferably 5°. Through the inclined surface structure of the clamping block 32, a force in an inclined direction is applied to the bent pipe 6, which makes it easier to cooperate with the clamp body 31 to clamp the bent pipe 6 when the clamping block 32 is clamped to the position between the clamp body 31 and the bent pipe 6, thereby increasing the stability of the connection; secondly, the positions of the two fixing clamps 3 fixing the bent pipe 6 are both on the same horizontal line, thereby ensuring the overall correction effect of the bent pipe 6; when one end of the bent pipe 6 is placed on the clamping side on the clamp body 31 and the end of the bent pipe 6 is stopped by the guide member 34, the cylinder 33 controls the movement of the clamping block 32, so that the clamping block 32 is clamped to the position between the clamp body 31 and the bent pipe 6, so that the clamping block 32 cooperates with the clamp body 31 to clamp the bent pipe 6, thereby fixing the end of the bent pipe 6 on the fixing clamp 3.

[0023] For further information, see Appendix Figure 3 As shown, the frame 1 is a two-layer structure, wherein the bottom plate 2 is installed at the lower layer of the frame 1, and the correction mechanism 5 is located at the upper layer of the frame 1, so that it is convenient for the correction mechanism 5 to perform top pressure correction on the bent pipe 6 from top to bottom.

[0024] In this embodiment, the correction mechanism 5 includes a top pressure block 51, a power module 52 that drives the top pressure block 51 to move the top pressure bend 6 in the vertical direction (the power module 52 is preferably hydraulically driven), two position sensors 53 for monitoring the top pressure block 51, a positioning member 54 and a limit member 55 for limiting the axial rotation of the top pressure block 51. The top pressure block 51 is connected to the power module 52 through a preset positioning pin, and the positioning member 54 is located between the top pressure block 51 and the power module 52. Specifically, when the top pressure block 51 is damaged and needs to be replaced, the positioning pins on the damaged top pressure block 51 and the power module 52 are disassembled, and the new top pressure block 51 is reinstalled on the power module 52, thereby avoiding the overall replacement of the correction mechanism 5, saving maintenance time, and reducing maintenance costs; secondly, by setting the positioning member 54 between the top pressure block 51 and the power module 52, the top pressure block 51 is limited to only vertical movement under the drive of the power module 52.

[0025] For further information, see Appendix Figure 3As shown, the limit member 55 includes a limit surface and an adjustment surface. The limit surface of the limit member 55 is formed with a guide groove 551 extending in the vertical direction, and the adjustment surface of the limit member 55 is formed with a limit groove 552 extending in the vertical direction and for positioning and installing the position sensor 53. Specifically, the position sensor 53 is arranged on the limit groove 552 at intervals along the vertical direction (the specific position can be set according to actual production requirements). Secondly, the position sensor 53 is triggered by synchronously moving the positioning member 54 vertically, thereby relatively limiting the range of vertical movement of the top pressure block 51, and real-time monitoring of the position of the top pressure block 51 facilitates the control of the production process.

[0026] As the fixing fixture 3 clamps the bent pipe 6 and the correction mechanism 5 presses the bent pipe 6 in the vertical direction, the detection mechanism 4 checks the correction degree of the bent pipe 6 .

[0027] For the convenience of explanation, the specific working process of the car trunk bend correction device in this embodiment is further explained below.

[0028] During the preparatory work: first, the cylinder 33 on the fixed clamp 3 moves the clamping block away from the clamping side of the clamp body 31. At the same time, the sliding member 44 on the measuring mechanism moves along the guide slide 43 on the fixed seat 42 to approach the position of the fixed clamp 3. Secondly, the power module 52 drives the top pressure block 51 to move upward in the vertical direction, so that the top pressure block 51 moves to the preset upper limit position of the position sensor 53; the deformed protruding part of the bent pipe 6 is directed toward the correction mechanism 5, and the two ends of the bent pipe 6 are placed on the two fixed clamps 3 respectively. After the end of the bent pipe 6 is stopped by the guide member 34, the cylinder 33 controls the movement of the clamping block 32 so that the clamping block 32 is clamped to the position between the clamp body 31 and the bent pipe 6, so that the clamping block 32 cooperates with the clamp body 31 to clamp the bent pipe 6, thereby fixing the end of the bent pipe 6 on the fixed clamp 3.

[0029] During the correction work: first, the power module 52 drives the pressing block 51 to move downward in the vertical direction, so that the pressing block 51 presses the deformed part of the bent pipe 6. Secondly, the pressing block 51 moves upward in the vertical direction again to the upper limit position of the preset position sensor 53; at the same time, the sliding member 44 on the measuring mechanism moves toward the position of the bent pipe 6 along the guide slide 43 on the fixed seat 42. If the corrected bent pipe 6 can be inserted into the measuring port 41a, the correction is successful, and the bent pipe 6 can be taken out and sent to the next process; otherwise, the bent pipe 6 is corrected again according to the actual deformation degree, thereby completing the correction work of the bent pipe 6.
