The existing laminating trial production of the inner plate and the outer plate of the automobile outer covering part generally adopts simple laminating equipment which is mainly divided into laminating equipment for pure manual laminating and laminating equipment for elegant hydraulic drive manual laminating. When the inner plate and the outer plate to be subjected to press-fitting treatment are placed on a tire mold of press-fitting equipment, the press-fitting is directly completed by manual hammering, the investment cost is lowest, but the product quality is difficult to guarantee, the working strength is high, and the working efficiency is low. For the elegance hydraulic drive manual pressing, which is called as 'Eckold sizing' abroad as shown in fig. 1, a forming die with a guide groove and a jag movable clamp 200 with an insert are manually held to complete the pressing of the gentle areas of the inner plate and the outer plate to be pressed and processed, so that the working strength can be reduced, the pressing quality is better than that of pure manual pressing, but the corner areas of the inner plate and the outer plate are still pressed by manual hammering, and the quality consistency of trial products is poor.
Furthermore, as shown in fig. 2, in the prior art, the robotic binding press-fitting equipment 300 is generally used for large, medium-scale production, and occasionally for small-scale production.

In addition, in the prior art, when the robot binding and pressing device 300 is used for pressing the inner plate and the outer plate for small-batch production, a piano key type pressing and cylinder clamping is generally adopted, and the clamp valve island or the robot control cabinet is controlled by the PLC cabinet to be used as a control main station to control the inner plate and the outer plate to be clamped, and the robot binding head is matched to complete the batch pressing production.

Therefore, it is highly desirable to provide a robot binding and stitching clamping device for trial production, which is low in manufacturing cost, suitable for trial production, and capable of improving stitching quality when the roller head stitches corners of the inner plate and the outer plate.

As shown in fig. 3 to 4, the trial-manufacture robot trimming, pressing, and clamping device provided in this embodiment is mainly applied to the trimming, pressing, and processing process in the field of automobile manufacturing, and is used for positioning, clamping, and fixing the inner plate and the outer plate of the automobile outer cover, so as to complete the trimming, pressing, and manufacturing of the inner plate and the outer plate by matching with the roller head 100 of the robot. The trial-manufacture robot edging, pressing and clamping device comprises a moulding bed 1, a manual positioning mechanism and a manual clamping mechanism. In this embodiment, the manual positioning mechanism includes a plurality of inner plate positioning assemblies 6 respectively annularly disposed around the tire casing 1 and an outer plate positioning member 5 disposed on the side clamping assembly 3 in a one-to-one correspondence manner, and the manual clamping mechanism includes a plurality of corner clamping assemblies 2 and a plurality of side clamping assemblies 3 respectively annularly disposed around the tire casing 1. In the prior art, the edge rolling pressing and clamping device adopts a cylinder to drive the material pressing blocks to clamp the corners of the inner plate and the outer plate, when the corner of the inner plate and the outer plate is pressed by the roller head 100 of a robot, the material pressing blocks used for clamping the corner positions of the inner plate and the outer plate are loosened firstly, and then the roller head 100 carries out pressing treatment on the corners of the inner plate and the outer plate. Since the corners of the inner and outer plates are not clamped at this time, the inner and outer plates are easily separated and tilted when the roller head 100 presses the corners of the inner and outer plates, which results in a problem of reduced pressing quality. To solve this problem, in the present embodiment, a corner clamp assembly 2 is rotatably provided at a corner of each of the molding beds 1. When rolling head 100 through the corner of fetal membrane 1, corner clamping component 2 can press from both sides the corner of tight inner panel and planking, and corner clamping component 2's main part can also rotate around the axis of the corner clamping face of approximate perpendicular to inner panel and planking in order to dodge and roll head 100, and make and roll the corner that head 100 can pressfitting inner panel and planking, the pressfitting in-process need not to loosen and presss from both sides tightly, and then when having solved the corner of rolling head 100 pressfitting inner panel and planking among the prior art, inner panel and planking separation perk appear very easily, and lead to the problem that the pressfitting quality reduces.
In the actual binding pressfitting course of working, the planking is placed on child mould 1, and the inner panel is folded on the planking, and the contour all around of inner panel is similar with the contour all around of planking, and the size contour of inner panel is less than the planking uniformly. A plurality of corner clamping assemblies 2 of the manual clamping mechanism clamp and fix corners of the inner plate and the outer plate, and a plurality of side clamping assemblies 3 clamp and fix sides of the inner plate and the outer plate. Meanwhile, the outer plate positioning piece 5 arranged on the side clamping component 3 can also be pressed on the outer edge of the outer plate, so that the outer plate can be positioned in the horizontal direction. And a plurality of inner plate positioning assemblies 6 achieve positioning of the inner plates on the outer plates in the horizontal direction. The roller head 100 can move around the tire membrane 1 according to a stitching route set by a program, and the outer plate can wrap the inner plate by turning over the vertical edges of the outer plate for many times, so that stitching connection of the inner plate and the outer plate is completed, when the roller head 100 passes through the corner of the tire membrane 1, the corner clamping assembly 2 can clamp the corners of the inner plate and the outer plate, the main body of the corner clamping assembly 2 can rotate around the axis which is approximately perpendicular to the corner clamping surfaces of the inner plate and the outer plate to avoid the roller head 100, and the roller head 100 can stitch the corners of the inner plate and the outer plate.
First, compared with the manual binding and pressing and the elegant hydraulic drive manual binding in the existing trial production process, the robot binding and pressing clamping device for trial production of the embodiment completes the positioning and clamping of the inner plate and the outer plate through the manual clamping mechanism and the manual positioning mechanism so as to complete the binding and pressing processing in cooperation with the roller head 100. The advantages are that: on one hand, a manual hand-held tool is not needed to complete pressing, the rolling head 100 replaces manual pressing, the error of manual pressing of operators is avoided, high-quality trial manufacturing of the inner plate and the outer plate is realized, and meanwhile, the pressing efficiency is improved; on the other hand, the operator can finish the clamping fixation of the inner plate and the outer plate fast through the manual clamping mechanism, the operation is simple and convenient, the clamping stability of the inner plate and the outer plate is ensured, the problem that the pressing quality is influenced by the looseness and deviation of the inner plate and the outer plate in the machining process is avoided as much as possible, the trial-manufacture clamping and pressing efficiency is far higher than that of a pure manual pressing mode and a elegant and high hydraulic drive manual pressing mode which are used in the trial-manufacture machining, and the method is more suitable for trial-manufacture production.
Secondly, compare with current robot binding pressfitting equipment, the manual clamping mechanism and the manual positioning mechanism of this embodiment are manual clamping adjustment to trial-manufacture production design, and its low in manufacturing cost, simple structure, convenient to use has guaranteed the stability of trial-manufacture product quality and pressfitting work simultaneously. When the roller head 100 passes through the corner of the tire membrane 1, the corner clamping component 2 can clamp the corner of the inner plate and the outer plate, the main body of the corner clamping component 2 can rotate around the axis which is approximately perpendicular to the corner clamping surface of the inner plate and the outer plate so as to avoid the roller head 100, and the roller head 100 can press the corner of the inner plate and the outer plate, so that the problem that the pressing quality is reduced due to the fact that the inner plate and the outer plate are separated and raised easily after the clamping of the corner of the inner plate and the outer plate is loosened in the prior art when the roller head 100 presses the corner of the inner plate and the outer plate is solved, and the pressing quality of the corner of the inner plate and the outer plate is. Therefore, the robot binding and pressing clamping equipment for trial production provided by the embodiment has the advantages of low design and manufacturing cost and capability of effectively improving the pressing quality of trial production.
In addition, in the trial hemming and pressing, after the inner and outer plates are placed on the tire mold 1, collapse deformation due to lack of support at the middle positions of the inner and outer plates is avoided. As shown in fig. 3, the middle area of the tire mold 1 is provided with a supporting block 12, and the supporting block 12 can abut against the lower surface of the outer plate, so that the quality of the pressed product is further improved, and the middle positions of the inner plate and the outer plate are prevented from collapsing and deforming.
Further, in order to ensure the precision of the stitching walking path of the roller head 100, as shown in fig. 4, a positioning calibration piece 13 is respectively disposed at four corners of the tire mold 1, and the positioning calibration piece 13 is used for positioning calibration of the robot. The roller head 100 is positioned according to the position of the positioning calibration piece 13, and the subsequent binding stitching walking track is determined, so that the working error of the roller head 100 is reduced, and the stitching quality of a trial product is ensured.
With respect to the positioning and clamping of the inner and outer panels, as shown in fig. 3-4, the present embodiment clamps the side edges of the inner and outer panels by a plurality of side clamping assemblies 3, and clamps the corners of the inner and outer panels by corner clamping assemblies 2.
As shown in fig. 4 to 5, a plurality of corner clamping assemblies 2 are rotatably disposed at corner positions of the tire mold 1 in a one-to-one correspondence. The corner clamping assembly 2 can rotate around an axis perpendicular to the clamping surface of the inner plate to avoid the roller head 100, so that the roller head 100 can complete the corner lamination of the inner plate and the outer plate in a state that the corner clamping assembly 2 clamps the corner areas of the inner plate and the outer plate, and the corner lamination quality of the corner positions of the inner plate and the outer plate is effectively improved.
Specifically, the number of the corner clamping assemblies 2 is four, and one corner clamping assembly 2 is arranged at each of four corners of the tire mold 1. The corner clamp assembly 2 includes, among other things, a mounting block 21, a rotating plate 22, a corner clamp 23, a rubber ram 24, and a vertical spindle 25. The detachable bolt of the mounting seat 21 is fixedly connected to the corner of the moulding bed 1, the mounting seat 21 is convenient to replace, and the mounting is simple. The shape of rotor plate 22 is L shape, and the one end of rotor plate 22 rotates through vertical pivot 25 and connects on mount pad 21, and vertical pivot 25 sets up along vertical direction, and rotor plate 22 can rotate around vertical pivot 25 horizontally. The corner clamping piece 23 is arranged at the other end of the rotating plate 22, a rubber pressure head 24 is arranged on the corner clamping piece 23, the rubber pressure head 24 can be pressed against the upper surface of the inner plate, the axis of the rubber pressure head 24 is approximately perpendicular to the corner clamping surfaces of the inner plate and the outer plate and is collinear with the axis of the vertical rotating shaft 25, so that in the rotating process of the corner clamping assembly 2 in the clamping state, the rubber deformation change of the rubber pressure head 24 is extremely small, the clamping state is basically unchanged, the clamping position of the rubber pressure head 24 is unchanged, the clamping is stable and reliable, and the rotating plate 22 and the corner clamping piece 23 can rotate to avoid the roller head 100.
Wherein, corner clamping piece 23 is the quick elbow of vertical type presss from both sides, and the cost that the quick elbow of vertical type pressed from both sides is 1/15 ~ 1/20 of cylinder drive pressure material piece cost about full automatic clamp equips, under the circumstances of the quality of guaranteeing to press from both sides, greatly reduced trial-manufacture input cost.
When the roller head 100 is going to pass through the corner positions of the inner plate and the outer plate, the roller head 100 can lift and separate from the outer plate, and then rotate the corresponding corner clamping assembly 2, so that the main body of the corner clamping assembly 2 is rotated to one side of the outer plate and the inner plate which is pressed by the roller head 100. Then, the roller head 100 returns to the position where the roller head 100 has just advanced again, the laminating track is repeated for 10-15mm, and the subsequent edge rolling and laminating processing is continued, so that the roller head 100 can laminate the corners of the inner plate and the outer plate under the condition that the corner clamping assembly 2 clamps the inner plate and the outer plate, and the laminating quality of the corner positions of the inner plate and the outer plate can be ensured to the maximum extent.
Or when the roller head 100 is going to pass through the corner positions of the inner plate and the outer plate, the roller head 100 is not lifted, but the main body of the corresponding corner clamping assembly 2 is horizontally rotated to a position far away from the roller head 100, so that the rotating plate 22 and the corner clamping piece 23 are avoided from the roller head 100, and the roller head 100 can be pressed through the corner positions of the inner plate and the outer plate. Then, after the roller head 100 moves through the corners of the inner plate and the outer plate, when the roller head cannot move forward continuously due to the blocking of the rotating plate 22 and the corner clamping piece 23, stopping the edge rolling and stitching of the roller head 100, loosening the corner clamping assembly 2, and rotating the corner clamping assembly 2 to the side of the inner plate and the outer plate which is already stitched by the roller head 100, so that the corner clamping assembly 2 avoids the roller head 100, and the corner clamping assembly 2 clamps the inner plate and the outer plate again; at this time, the corner clamping assembly 2 completely avoids the roller head 100, then the roller head 100 is restarted, and the subsequent edge rolling and pressing processing is continued. In the whole process, when the corner clamping assembly 2 is loosened, the roller head 100 finishes the pressing at the corner positions of the inner plate and the outer plate, and in the pressing process, the corners of the inner plate and the outer plate are always in a clamping state, so that the pressing quality at the corner positions of the inner plate and the outer plate can be ensured.
In addition, the present embodiment achieves clamping of the side edges of the inner and outer panels by the side edge clamping assembly 3. As shown in fig. 6 to 7, the number of the side clamping units 3 of the present embodiment is 10, and the side clamping units 3 are disposed at the side of the tire mold 1 at intervals. During the clamping operation, the side clamping assembly 3 can press the inner plate and the outer plate on the tire membrane 1. When the clamping is cancelled, the main body of the side clamping assembly 3 can also rotate to the outer side of the tire membrane 1, and then the inner plate and the outer plate are loosened. When the roller head 100 needs to pass through the position of the tire mold 1, where the side clamping assembly 3 is arranged, the main body of the side clamping assembly 3 can be turned over to the outer side of the tire mold 1, so that an avoiding space for avoiding the roller head 100 can be formed, and the roller head 100 can pass through.
Specifically, the side clamping assembly 3 includes a holder 31, a flip link 32, and a side clamp 33. The fixed seat 31 is arranged on the side edge of the tire mould 1; the turnover connecting rod 32 can be rotatably connected to the fixed seat 31; the side clamping members 33 are fixedly connected to the turnover connecting rods 32, and the side clamping members 33 can be turned over through the turnover connecting rods 32 and pressed against the upper side of the inner plate so as to clamp the inner plate and the outer plate. The side clamping pieces 33 can also be turned to the outer side of the tire membrane 1 through the turning connecting rods 32, so that the inner plate and the outer plate are not clamped, and the rolling head 100 is avoided.
Specifically, as shown in fig. 6 to 7, in this embodiment, one end of the fixing seat 31 is fixedly connected to the side edge of the tire mold 1 by a screw, and is convenient to disassemble and replace, a through groove is formed in the other end of the fixing seat 31, one end of the turning link 32 is rotatably connected and assembled in the through groove through the horizontal rotating shaft 34, and the other end of the turning link 32 is fixedly assembled with the side edge clamping member 33. In order to avoid that the position of the turnover connecting rod 32 is loosened to influence the side clamping piece 33 to clamp the inner plate and the outer plate after the turnover connecting rod 32 drives the side clamping piece 33 to turn over right above the tire mould 1. An overturning fixing bolt 321 is further inserted into one end of the overturning connecting rod 32 close to the horizontal rotating shaft 34, and an overturning fixing screw hole 322 is formed in the position of the fixing seat 31 corresponding to the overturning fixing bolt 321. After the turning connecting rod 32 drives the side clamping piece 33 to turn over to the position right above the tire mould 1, the turning fixing bolt 321 is connected to the turning fixing screw hole 322 through a bolt, so that the position of the turning connecting rod 32 is fixed, and the clamping stability of the side clamping piece 33 is guaranteed.
Wherein, side clamping piece 33 also is the quick elbow of rectilinear formula presss from both sides, and the cost that the quick elbow of rectilinear formula pressed from both sides is 1/15 ~ 1/20 of the cost of the cylinder drive pressure material piece in current robot binding pressfitting equipment, under the circumstances of the clamping quality of assurance, greatly reduced trial-manufacture input cost.
Further, the inner and outer plates are clamped on the tire membrane 1 more firmly and reliably by the side clamping assembly 3 due to the difference of the specific shapes of the parts of the inner plate to be clamped. As shown in fig. 6, in this embodiment, the rubber pressing block 35 is disposed on the side clamping member 33, the rubber pressing block 35 can be pressed against the inner plate, and the rubber pressing block 35 can be compressed and deformed adaptively according to the shapes of the inner plates at different positions, so that the clamping is more stable, flexible and reliable.
Further, since the inner plate and the outer plate are of a plate-shaped structure, the inner plate and the outer plate are easily bent and deformed, and if the distance between the clamping positions of the side clamping assemblies 3 is too large, the individual positions of the inner plate and the outer plate are not clamped easily, so that a gap is generated between the inner plate and the outer plate and the tire mold 1, and the pressing quality of the roller head 100 on the inner plate and the outer plate is affected.
