Detailed Description
As shown in fig. 1 to 4, the door sash profile correction tool in the present embodiment includes a base 1, a door positioning module disposed on the base 1, and a cutting device disposed on the base 1 for correcting the profile of the door sash. The cutting area is reserved when the door sash is machined, the door sash and the inner and outer plates of the door are welded to form the door assembly, stable positioning of the door assembly is achieved through the door positioning module, the reserved cutting area is cut off through the cutting device after positioning, the edge of the outline of the door sash is corrected, welding is prevented from influencing the outline of the door sash, the matching degree of the outline of the door sash and the outline of the door is improved, and the appearance quality of the whole vehicle is guaranteed.
In this embodiment, the cutting device comprises a mounting pillar 21, a hydraulic shear 22 rotatably disposed at the top end of the mounting pillar 21, a supporting pillar 23, and a sash support 24 fixed on the top of the supporting pillar 23 for providing a supporting surface for modifying the contour of the door sash; the window frame support 24 is provided with a groove 24a into which the cutting edge of the hydraulic shear 22 enters. The hydraulic shears 22 are hinged to the top ends of the mounting upright posts 21, after the vehicle door assembly is positioned through the vehicle door positioning module, the vehicle door window frame is attached to the supporting surface of the window frame supporting piece 24, the hydraulic shears 22 are rotated to enable the cutting edges to enter the grooves 24a, redundant edges reserved in the vehicle door window frame are cut off, and the correction of the outline edges of the vehicle door window frame is achieved.
In this embodiment, the door positioning module includes a supporting component 31 for supporting the door assembly to be tilted, a limiting component 32 for preventing the door assembly from sliding downwards along the tilting direction, and a clamping component for clamping two sides of the door assembly; the upper surface of the sash support member 24 forms an inclined curved surface that abuts the lower surface of the door sash. The support member 31 supports the door assembly so that it tilts, the door assembly slides downward along the tilted support surface under the action of gravity, however, the base 1 is further provided with a limiting component 32, the limiting component 32 may be one or more limiting blocks, one side of the limiting block facing the door assembly abuts against the bottom of the door assembly, the door assembly is prevented from sliding downwards along the inclined supporting surface, meanwhile, the clamping components clamp two sides of the vehicle door assembly, so that the vehicle door positioning module can incline and stably fix the vehicle door assembly, at the moment, the upper surface of the window frame supporting piece 24 is in conformal fit with the lower surface of the vehicle door window frame, the upper surface of the sash support member 24 is also inclined, so that it is convenient to operate the hydraulic shears 22 for cutting work, and the oblique arrangement of the door assembly leads to that the edge of the door sash is cut gradually from top to bottom, so that the integral synchronous cutting quality is better relative to the door assembly. Of course, the assembly vehicle door can be fixed horizontally or vertically, and due to the fact that gravity is used for positioning, the assembly vehicle door needs more positioning devices for horizontal or vertical fixing, and on the other hand, operation is inconvenient during cutting, and cutting quality is difficult to guarantee.
In this embodiment, the supporting component 31 includes a plurality of supporting blocks with bottom ends fixed on the base 1, the upper end surfaces of the supporting blocks are inclined surfaces, and the upper end surfaces of the supporting blocks are attached to the inclined vehicle door to form a supporting surface. The supporting blocks are four, and the height of two supporting blocks close to the limiting component 32 is lower than that of the other two supporting blocks.
In this embodiment, the clamping assembly includes a plurality of sets of clamping and centering mechanisms; the clamping and centering mechanism comprises a fixed upright column 331, a connecting rod 332 with the middle part rotatably arranged at the top of the fixed upright column 331, cross rods 333 rotatably arranged at two ends of the connecting rod 332 respectively, and a clamping piece 334 fixed at one end of the cross rods 333 far away from the connecting rod 332. Two groups of clamping and centering mechanisms are arranged, and the height of the clamping piece 334 of two clamping and centering mechanisms close to the limiting assembly 32 is lower than that of the clamping pieces 334 of the other two clamping and centering mechanisms. The position of fixed stand 331 corresponds door assembly middle part, connecting rod 332 middle part articulates at fixed stand 331 top, two horizontal poles 333 articulate respectively at connecting rod 332 both ends, rotate connecting rod 332 and horizontal pole 333, make two holder 334 keep great distance, the door assembly is placed on supporting component 31 after, rotate connecting rod 332, make two holder 334 centre gripping door assembly both sides, because fixed stand 331 position corresponds door assembly middle part, two horizontal poles 333 length is unanimous, so press from both sides tight centering mechanism and can realize the function of centering restriction door assembly displacement.
The invention also discloses a vehicle door sash profile correction method, which uses the vehicle door sash profile correction tool and comprises the following steps:
s1, processing the door sash, and reserving a cutting area at one side of the door sash;
s2, welding the door sash and the inner and outer plates of the door to form a door assembly;
s3, fixing the vehicle door assembly on the vehicle door sash contour correction tool;
and S4, cutting the reserved cutting area of the door sash by using a cutting device, and realizing the correction of the edge profile of the sash.
The conventional technology is adopted for processing the door sash and welding the door sash and the inner and outer plates of the door, and the detailed description is omitted.
In this embodiment, the reserved cutting area is located on the side of the door sash close to the rear of the vehicle. The edge of the door sash close to one side of the tail of the vehicle is relatively straight, the trend of the cutting edge of the hydraulic shear 22 is the same as that of the edge, and compared with the edge of the door sash close to one side of the vehicle door, the edge required to be cut is relatively straight when the reserved cutting area is cut, so that the operation is simpler, and the cutting quality is higher.
In this embodiment, the width of the reserved cutting area is 10-100 mm. The width is preferably 12-70mm, although widths greater than 100mm will not affect the actual processing, but will result in a greater waste of material.
In this embodiment, in step S3, the door assembly is placed on the support component 31, the bottom of the door assembly is abutted against the limit component 32, and then the connecting rods 332 of the clamping and centering mechanisms are rotated to make the clamping pieces 334 at the ends of the cross rods 333 respectively abut against the two sides of the door assembly, so as to position the door assembly, and at this time, the lower surface of the door sash is attached to the upper surface of the sash support member 24. The fixing of the door assembly in the desired position can be achieved by a simple operation, and then the hydraulic shears 22 are operated to cut the edge of the door sash, resulting in a correction of the sash edge profile.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
