Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle technology, specifically relating to a new energy vehicle air intake volute straightening machine. Background Technology

[0002] In recent years, the automotive parts industry, primarily focused on new energy vehicles, has relied on new energy vehicle platforms for continuous iteration and updates, with systems such as fresh air systems increasingly appearing in these vehicles. Currently, the air intake casing in these fresh air systems is a key component for guiding and accelerating airflow. Its manufacturing process often involves injection molding, but the finished casing is prone to physical deformation after being removed from the mold. Furthermore, the casing itself undergoes physical deformation during normal use, leading to airflow turbulence, noise, and other hazards. Therefore, a structure is needed to correct the deformation of the fresh air intake casing in new energy vehicles. Summary of the Invention

[0003] In view of this, the present invention discloses a new energy vehicle air intake volute straightening machine, the purpose of which is to solve the problem of the need to straighten the deformation of the new energy vehicle air intake volute.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A new energy vehicle air intake volute straightening machine includes a base, an annular seat coaxially rotatably connected to the base, a drive structure for rotating the annular seat on the base, and several support and fastening structures for fixing the sidewalls of the volute at the top of the annular seat; a sliding groove facing the axis is opened inside the base, the two ends of the sliding groove extending upward through the base, a C-shaped cylinder bracket is horizontally slidably arranged in the sliding groove, a straightening cylinder is fixed at each end of the cylinder bracket, and a horizontally arranged flattening roller is rotatably connected to each end of the straightening cylinder; a drive cylinder for moving the cylinder bracket is arranged in the sliding groove.

[0006] In this scheme, the concave surface of the volute is placed face down on the supporting and fastening structure, which supports and fixes the volute, suspending it in the air. At this point, a drive cylinder moves the cylinder bracket, aligning the straightening cylinder on the bracket with the rotation trajectory of the volute's deformation area. The straightening cylinder is then extended, causing both leveling rollers to simultaneously and tightly contact the volute. Next, the drive structure rotates the annular seat, which in turn rotates the volute through the supporting and fastening structure. When the deformation area of ​​the volute rotates to contact the leveling rollers, the two leveling rollers simultaneously compress the deformation area for straightening. The drive cylinder then moves the cylinder bracket again, aligning the straightening cylinder with the rotation trajectory of the other deformation area of ​​the volute, repeating the process until straightening is complete. In this solution, two leveling rollers simultaneously apply force to the inner and outer walls of the volute, which can correct the volute while preventing overcorrection. In addition, the volute is rotated by the drive structure and the ring seat, which can quickly correct a large area of ​​the volute and effectively shorten the correction time.

[0007] Furthermore, the supporting and fastening structure includes a support slidably connected to the annular seat, and a locking structure provided on the support for locking the support to one of the annular seat or the base; a guide rail is horizontally provided at the top of the support and faces the center of the annular seat, and a slide block is slidably connected to each guide rail, and each slide block has an installation groove parallel to the groove at its top; an adjusting rod is rotatably connected in the installation groove and is parallel to the groove; the two ends of the adjusting rod are provided with threads in opposite directions; two symmetrically arranged mounting seats are slidably connected in the installation groove; the mounting seats are threaded to the corresponding ends of the adjusting rods; an installation rod is vertically slidably provided on each mounting seat; a locking pin is provided on the mounting seat for locking the installation rod; and a clamping roller is coaxially rotatably connected to the installation rod.

[0008] In this design, the height of the clamping rollers is adjusted by vertically sliding the mounting rod according to the height of the volute, and the mounting rod is fixed by locking pins. The volute sidewall is positioned between the two clamping rollers by sliding the slide block. Rotating the adjusting rod forward causes the mounting seats at both ends of the adjusting rod to move towards each other, which in turn drives the two clamping rollers to move synchronously until they are tightly fitted against the volute sidewall. Multiple clamping rollers on the slide blocks form a multi-point clamping and fixing of the volute. When the upper and lower end faces of the volute are being straightened, a locking structure locks all supports to the annular seat, allowing all supports to move synchronously with the annular seat. When the volute sidewall needs straightening, the locking structure on the support facing the deformed area of ​​the volute sidewall is connected to the base, fixing the support to the base. As the volute rotates with the annular seat, the clamping rollers corresponding to the support apply force to the inner and outer walls of the deformed area of ​​the volute sidewall, performing the sidewall straightening operation. In this solution, the combination of the above structures enables the solution to adapt to various sizes of volutes, and at the same time, it can accurately correct the deformation of the volute sidewall, greatly improving the accuracy of volute correction.

[0009] Furthermore, the locking structure includes a through groove on the outer wall of the support, a rotating shaft rotatably disposed in the middle of the through groove and perpendicular to the support, two mutually perpendicular positioning rods fixed on the rotating shaft, a plurality of first slots engaging with the positioning rods on the outer periphery of the annular seat, and a plurality of second slots engaging with the positioning rods on the base, the second slots being distributed in a ring.

[0010] In this solution, when the support needs to be locked with the ring seat, simply rotate the shaft to make the corresponding positioning rod engage in the corresponding first slot; at this time, the other positioning rod on the shaft disengages from the second slot; when the support needs to be locked with the base, simply rotate the shaft to make the corresponding positioning rod engage in the corresponding second slot; at this time, the other positioning rod on the shaft disengages from the first slot; the whole operation process is simple and quick.

[0011] Furthermore, an L-shaped auxiliary bracket is fixed to the bottom of the cylinder bracket, and the correction cylinder located below is fixed on the auxiliary bracket.

[0012] Furthermore, both the leveling roller and the pressing roller are equipped with electric heating coils.

[0013] Furthermore, the support is provided with diagonal bracing rods for supporting the guide rail.

[0014] Furthermore, the cylinder bracket is provided with reinforcing ribs.

[0015] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0022] like Figures 1-4 As shown:

[0023] A new energy vehicle air intake volute 1 straightening machine includes a base 2, an annular seat 3 coaxially rotatably connected to the base 2, and a drive structure for driving the annular seat 3 to rotate (in this embodiment, the drive structure is driven by a motor, which is a conventional technical means and therefore not described in detail). The top of the annular seat 3 is provided with several support and fastening structures for fixing the sidewalls of the volute 1. A sliding groove facing the axis is opened inside the base 2, and the two ends of the sliding groove extend upward through the base 2. A C-shaped cylinder bracket 4 is horizontally slidably arranged in the sliding groove. A straightening cylinder 5 is fixed to each end of the cylinder bracket 4 and is rotatably connected to a horizontally arranged flattening roller 6. A drive cylinder 7 for driving the cylinder bracket 4 to move is provided in the sliding groove.

[0024] In this scheme, the concave surface of the volute 1 is placed on the supporting and fastening structure, which supports and fixes the volute 1, suspending it in the air. At this time, the drive cylinder 7 pushes the cylinder bracket 4 to move, aligning the straightening cylinder 5 on the cylinder bracket 4 with the rotation trajectory of the volute 1's deformation area. The straightening cylinder 5 is then extended, causing the two leveling rollers 6 to simultaneously and tightly contact the volute 1. The drive structure then rotates the annular seat 3, which in turn rotates the volute 1 through the supporting and fastening structure. When the deformation area of ​​the volute 1 rotates to contact the leveling rollers 6, the two leveling rollers 6 simultaneously press the deformation area of ​​the volute 1 for straightening. The drive cylinder 7 pushes the cylinder bracket 4 again, aligning the straightening cylinder 5 with the rotation trajectory of another deformation area of ​​the volute 1, repeating the operation until the straightening is complete. The upper and lower end faces of the protruding part of the volute 1 are straightened by directly pressing the upper and lower end faces of the volute 1 with the two pressing rollers 14, without rotating the volute 1.

[0025] In this scheme, two leveling rollers 6 apply force to the inner and outer walls of the volute 1 simultaneously, which can prevent over-correction while performing correction. In addition, the volute 1 is rotated by the cooperation of the drive structure and the ring seat 3, which can quickly correct the volute 1 over a large area and effectively shorten the correction time.

[0026] In this embodiment, the supporting and fastening structure includes a support 8 slidably connected to the annular seat 3. The support 8 is provided with a locking structure, which is used to lock the support 8 to one of the annular seat 3 and the base 2. The top of the support 8 is horizontally provided with a guide rail 9 facing the center of the annular seat 3. Each guide rail 9 is slidably connected with a slide block 10. Each slide block 10 has an installation groove parallel to the groove at its top. An adjusting rod 11 is rotatably connected to the groove and is parallel to it (the rotation of the adjusting rod 11 can be driven by a motor or manually rotated, which is a conventional technical means and therefore not described in detail). The two ends of the adjusting rod 11 are provided with threads with opposite directions of rotation. Two symmetrically arranged mounting seats 12 are slidably connected to the mounting groove. The mounting seats 12 are threadedly connected to the corresponding ends of the adjusting rod 11. Each mounting seat 12 is vertically slidably provided with a mounting rod 13. The mounting seat 12 is provided with a locking pin for locking the mounting rod 13. A clamping roller 14 is coaxially rotatably connected to the mounting rod 13.

[0027] In this design, the height of the clamping rollers 14 is adjusted by vertically sliding the mounting rod 13 according to the height of the volute 1, and the mounting rod 13 is fixed by a locking pin. The sliding slide 10 is used to position the sidewall of the volute 1 between the two clamping rollers 14. At this time, rotating the adjusting rod 11 forward causes the mounting seats 12 at both ends of the adjusting rod 11 to move towards each other. The mounting seats 12 then drive the two clamping rollers 14 to move synchronously until the two clamping rollers 14 are tightly fitted against the sidewall of the volute 1. Multiple clamping rollers 14 on the sliding seats 10 form multiple clamping forces on the volute 1. Point clamping and fixing; when straightening the upper and lower end faces of the volute 1, the locking structure locks all supports 8 to the annular seat 3, allowing all supports 8 and the annular seat 3 to move synchronously; when the side wall of the volute 1 needs to be straightened, the locking structure on the support 8 facing the deformed area of ​​the side wall of the volute 1 is connected to the base 2, fixing the support 8 to the base 2. When the volute 1 rotates with the annular seat 3, the corresponding clamping roller 14 of the support 8 applies force to the inner and outer walls of the deformed area of ​​the side wall of the volute 1 to perform the side wall straightening operation. In addition, when the support 8 is about to contact the adjacent support 8, the drive structure should be stopped, and the adjacent support 8 should be used to continue straightening the deformed area.

[0028] In this solution, through the combination of the above structures, this solution can adapt to various specifications of volute 1, and at the same time, it can accurately correct the deformation of the side wall of volute 1, greatly improving the accuracy of volute 1 correction.

[0029] In this embodiment, the locking structure includes a through groove on the outer wall of the support 8, a rotating shaft 15 rotatably disposed in the middle of the through groove and perpendicular to the support 8, and two mutually perpendicular positioning rods 16 fixed on the rotating shaft 15. The outer periphery of the annular seat 3 is provided with a plurality of first slots 17 that engage with the positioning rods 16, and the base 2 is provided with a plurality of second slots 18 that cooperate with the positioning rods 16. The second slots 18 are distributed in a ring.

[0030] In this solution, when the support 8 needs to be locked with the ring seat 3, simply rotate the shaft 15 to make the corresponding positioning rod 16 engage in the corresponding first slot 17; at this time, the other positioning rod 16 on the shaft 15 disengages from the second slot 18; when the support 8 needs to be locked with the base 2, simply rotate the shaft 15 to make the corresponding positioning rod 16 engage in the corresponding second slot 18; at this time, the other positioning rod 16 on the shaft 15 disengages from the first slot 17; the whole operation process is simple and quick.

[0031] In this embodiment, an L-shaped auxiliary bracket 19 is fixed at the bottom of the cylinder bracket 4, and the correction cylinder 5 located below is fixed on the auxiliary bracket 19.

[0032] By setting up an auxiliary bracket 19, collisions between the lower correction cylinder 5 and structures such as the annular seat 3 are avoided.

[0033] In this embodiment, both the leveling roller 6 and the pressing roller 14 are equipped with electric heating coils.

[0034] By setting up electric heating coils, heat is generated on the leveling roller 6 and the pressing roller 14, and the heat is transferred to the deformation area of ​​the volute 1, which can effectively accelerate the correction of the volute 1.

[0035] In this embodiment, the support 8 is provided with a diagonal brace 20 for supporting the guide rail 9.

[0036] By setting diagonal bracing rods 20, the guide rail 9 is prevented from bending downwards.

[0037] In this embodiment, the cylinder bracket 4 is provided with reinforcing ribs 21.

[0038] By setting reinforcing ribs 21, the bending deformation of the cylinder bracket 4 is prevented, which would reduce the correction accuracy of the volute 1.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
