Description

Technical Field

[0001] The invention relates to sheet metal repair equipment, in particular to disassembly-free sheet metal repair equipment. Background Art

[0002] Cars are prone to accidental collisions during driving. The dents caused by the collision can be repaired through simple car sheet metal repairs. A common traditional repair method is to repair the dented area by hammering with hammering equipment. This method requires frequent replacement of different hammers to perform multiple processing steps, and the operation is more troublesome. Another common traditional repair method is to attach hot melt glue to the puller to assist in fixing the puller. This method requires repeated use of a large amount of hot melt glue, which is not easy to clean up later.

[0014] The beneficial effects of the present invention are as follows: 1.

[0015] 2. After the electric push rod is started, the gas in the puller is sucked into the vacuum cylinder through the second connecting pipe and the first connecting pipe, thereby forming a negative pressure of gas inside and outside, so that the puller is fastened and adsorbed on the car body by vacuum adsorption;

[0016] 3. The push plate continues to move left and contacts the U-shaped rod, driving the U-shaped rod to move left, thereby driving the second slider to slide left, and then driving the puller to move left. The puller flattens the concave part of the car body outward. Compared with the sheet metal repair method of hot melt adhesive, the negative pressure suction mechanism of the present invention forms a linkage with the pulling mechanism, which is more efficient and convenient.

[0017] 4. The lock is stuck in the second slide rail, which makes the second slide block temporarily unable to slide, preventing the puller from sliding to the left and detaching from the car body, thus affecting the subsequent repair. The puller is then fastened and adsorbed on the car body by vacuum adsorption, thereby improving the success rate of automobile sheet metal repair;

[0018] 5. After the first slider moves up and down to the appropriate height, the maintenance personnel releases the second pressure plate, and the third spring resets to drive the clamping block to slide outward and re-jam the clamping sleeve, so that the first slider is fixed to prevent the first slider from sliding downward due to the gravity of the component itself, causing the puller to deviate downward from the sunken area of ​​the vehicle body, thereby affecting the repair effect;

[0019] 6. When the puller pulls the car body to the left, the blocking mechanism as a whole plays a role similar to a door blocker, so that the entire disassembly-free sheet metal repair equipment can only move left but not right, thereby improving the repair effect of automobile sheet metal;

[0020] 7. The maintenance personnel grasp the middle part of the second hinged sleeve and drive the brush head to swing back and forth, so that the brush head can fully remove the dust in the sunken area of ​​the car, further improving the car sheet metal repair effect.

The right side of the push plate 65 contacts the second slider 62, and the push plate 65 moves left to contact the U-shaped rod 63.

[0041] like Figure 6 , Figure 7 and Figure 8As shown, the negative pressure suction mechanism 7 includes a support frame 71, a vacuum cylinder 72, a piston rod 73, a first pressure plate 74, a first spring 75, a first connecting pipe 76, a second connecting pipe 77, a guide rod 78 and a wedge rod 79. A support frame 71 is provided in the middle of the lower part of the second slider 62, and five vacuum cylinders 72 are evenly arranged on the right side of the upper part of the support frame 71. The five vacuum cylinders 72 are arranged at intervals in the longitudinal direction. A piston rod 73 is slidably provided in the lower part of the vacuum cylinder 72. A first pressure plate 74 is connected between the bottom ends of the piston rods 73. The first pressure plate 74 is slidably connected to the support frame 71. Four first springs 75 are wound around the upper right part of the support frame 71. The two ends of a spring 75 are respectively connected to the support frame 71 and the first pressure plate 74. The four first springs 75 are respectively located between two adjacent vacuum cylinders 72. The top of the vacuum cylinder 72 is connected to a first connecting pipe 76. The left part of the puller 4 is provided with a second connecting pipe 77. The left end of the second connecting pipe 77 is rotatably connected to the adjacent first connecting pipe 76. A guide rod 78 is connected between the middle of the left side of the support frame 71 and the second slider 62. The guide rod 78 is slidably connected to the first pressure plate 74. Wedge rods 79 are fixed on both sides of the front and rear of the top of the first pressure plate 74. The push plate 65 moves left and first contacts the wedge rod 79 and then contacts the U-shaped rod 63.

[0042] When maintenance personnel need to repair the sheet metal of an automobile, they can use this sheet metal repair equipment. First, the maintenance personnel move the equipment as a whole to the automobile that needs sheet metal repair through the universal wheel 2, and adjust the first slider 51, the mounting sleeve 52, the rotor 53, the shaft tube 54, the first hinge sleeve 55, the puller 4, the second slide rail 61, the second slider 62, the U-shaped rod 63, the electric push rod 64, the push plate 65, the support frame 71, the vacuum cylinder 72, the piston rod 73, the first pressure plate 74, the first spring 75, the first connecting pipe 76, the second connecting pipe 77, the guide rod 78 and the wedge rod 79 as a whole up and down, and then swing the mounting sleeve 52 left and right and swing the rotor 53 up and down to adjust the first slider 51, the second slider 62, the U-shaped rod 63, the electric push rod 64, the push plate 65, the support frame 71, the vacuum cylinder 72, the piston rod 73, the first pressure plate 74, the first spring 75, the first connecting pipe 76, the second connecting pipe 77, the guide rod 78 and the wedge rod 79 as a whole up and down. The rail 61, the second slider 62, the U-shaped rod 63, the electric push rod 64, the push plate 65, the support frame 71, the vacuum cylinder 72, the piston rod 73, the first pressure plate 74, the first spring 75, the first connecting pipe 76, the second connecting pipe 77, the guide rod 78 and the wedge rod 79 swing as a whole, so that the effect of roughly adjusting the height and pitch angle of the puller 4 according to the sunken area of ​​the car body is achieved. When the sunken area is small, the maintenance personnel rotate the puller 4 corresponding to the non-sunken area upward by 90 degrees away from the car body, and the puller 4 rotated 90 degrees upward drives the corresponding second connecting pipe 77 to rotate 90 degrees upward. When the sunken area is large, the puller 4 corresponding to the sunken area is rotated to align with the sunken part of the car body, so that the specific fine adjustment according to the size of the sunken area of ​​the car body is achieved. The number of pullers 4 can be reasonably increased or decreased to achieve the effect that the corresponding puller 4 after adjustment is fully fitted with the sunken area of ​​the car body, thereby improving the efficiency of the car's sheet metal repair. Then the maintenance personnel starts the electric push rod 64, and the telescopic rod of the electric push rod 64 contracts to drive the push plate 65 to move left. The push plate 65 moves left and first contacts the wedge rod 79 and continues to move left to drive the wedge rod 79 to move downward, thereby driving the first pressure plate 74 to slide downward along the guide rod 78, the first spring 75 is stretched, and then drives the first pressure plate 74 to slide downward along the vacuum cylinder 72, and the gas in the puller 4 is sucked into the vacuum cylinder 72 through the second connecting pipe 77 and the first connecting pipe 76, thereby forming a negative pressure of gas inside and outside, so that the puller 4 is fastened and adsorbed on the car body by vacuum adsorption, and the push plate After the push rod 65 continues to move left and contacts the U-shaped rod 63, it drives the U-shaped rod 63 to move left, thereby driving the second slider 62 to slide left along the second slide rail 61, and then driving the shaft tube 54, the first hinge sleeve 55 and the puller 4 to move left, and the puller 4 pulls the concave part of the vehicle body outward, which is more efficient and convenient than the sheet metal repair method of hot melt adhesive. After the telescopic rod of the electric push rod 64 shrinks to a certain extent, it can be controlled to extend until it is separated from the wedge rod 79, thereby driving the push plate 65 to move a little distance to the right, and the first spring 75 resets to drive the first pressure plate 74 to slide upward, and the first pressure plate 74 drives the wedge rod 79 to move upward, and the gas in the vacuum cylinder 72 is pushed outward by the first pressure plate 74 through the first connecting pipe 76 and the second connecting pipe 77, so that the puller 4 is separated from the vehicle body. After separation,The maintenance personnel move the entire non-disassembly sheet metal repair device to the left and away from the vehicle body, and then control the telescopic rod of the electric push rod 64 to continue to extend, so that the push plate 65 moves right to contact the second slider 62 and drives the second slider 62 to slide right to reset, thereby driving the shaft tube 54, the first hinge sleeve 55 and the puller 4 to move right to reset, and repeat the above steps to perform multiple repairs until the repair is completely completed.

[0043] Example 2

[0044] On the basis of Example 1, Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the self-locking mechanism 8 is also included. The self-locking mechanism 8 includes a lock 81, a second spring 82, a pull rope 83, a first rotating shaft 84, a guide wheel 85, a guide sleeve 86 and a third slider 87. The second slide rail 61 has a clamping hole on both the front and rear sides of the right side. The second slide rail 61 has a lock 81 on both the front and rear sides of the upper part. The lock 81 is slidably provided. The lock 81 is clamped in the clamping hole on the same side. The lock 81 slides inwardly and disengages from the second slide rail 61. The inner side of the lock 81 is connected to the second slider 62 with a second spring 82. The second slider 62 A first rotating shaft 84 is provided on both the front and rear sides of the top through bearings, and a guide wheel 85 is provided on the first rotating shaft 84 through a key connection. Guide sleeves 86 are provided on the upper and lower parts of the outer side of the U-shaped rod 63, and a third slider 87 is slidably connected between the upper and lower guide sleeves 86. When the push plate 65 moves left, it first contacts the wedge rod 79, then contacts the third slider 87, and then contacts the U-shaped rod 63. A pull rope 83 is connected between the upper part of the third slider 87 and the lock 81 on the same side, and the pull rope 83 passes around the guide wheel 85 on the same side.

[0045] When the push plate 65 moves to the left and contacts the wedge rod 79, the entire non-disassembly sheet metal repair device may shake, causing the second slider 62 to slide to the left at will, thereby causing the puller 4 to separate from the vehicle body, and it is impossible to fasten the puller 4 to the vehicle body by vacuum adsorption. Therefore, the lock 81 is initially stuck in the second slide rail 61, so that the second slider 62 cannot slide temporarily, which is convenient for the subsequent fastening and adsorption of the puller 4 to the vehicle body by vacuum adsorption. After adsorption, the push plate 65 continues to move to the left and contacts the third slider 87 and drives the third slider 87 to slide to the left along the guide sleeve 86. The guide sleeve 86 pulls the lock 81 to slide inward through the pull rope 83, and the second spring 82 is compressed, so that the lock 81 and the second slide rail 61 are no longer engaged, which is convenient for the subsequent push plate 65 to continue to move to the left to drive the U-shaped rod 63 and The second slider 62 slides to the left, so that the depressed area of ​​the automobile is flattened outward by the puller 4. The left movement of the second slider 62 drives the first rotating shaft 84, the guide wheel 85, the guide sleeve 86 and the third slider 87 to move to the left as a whole. When the push plate 65 moves to the right, the push plate 65 is disengaged from the U-shaped rod 63, the third slider 87 and the wedge rod 79. The right movement of the second slider 62 drives the first rotating shaft 84, the guide wheel 85, the guide sleeve 86 and the third slider 87 to move to the right as a whole. When the lock 81 moves to the right to correspond to the corresponding card hole, the second spring 82 resets and drives the lock 81 to slide outward and get stuck in the second slide rail 61, thereby locking the second slider 62, preventing the puller 4 from sliding to the left and separating from the car body, thereby affecting subsequent repairs and improving the success rate of automobile sheet metal repairs. The lock 81 slides outward and pulls the guide sleeve 86 to slide to the right and resets through the pull rope 83.

[0046] like Figure 1 , Figure 3 , Fig.11 and Fig.12 As shown, the clamping mechanism 9 is also included, and the clamping mechanism 9 includes a first mounting frame 91, a clamping block 92, a third spring 93, a clamping sleeve 94, a first wedge block 95, a second wedge block 96 and a second pressure plate 97. The first mounting frame 91 is provided on the upper left side of the mounting frame 1. The first mounting frame 91 is located on the left side of the first slide rail 3. The clamping block 92 is slidably provided on both the front and rear sides of the first mounting frame 91. The third spring 93 is evenly provided between the clamping block 92 and the inside of the first mounting frame 91 from top to bottom. The first slider 51 is provided inside A clamping sleeve 94 is provided on both the front and rear sides of the part, and the clamping sleeve 94 is engaged with the clamping block 92 on the same side. A first wedge block 95 is slidably provided on both the front and rear sides of the lower part of the installation frame 1, and the first wedge block 95 slides inwardly to contact the clamping block 92 on the same side, and the inclined surface of the first wedge block 95 faces outward. A second pressing plate 97 is slidably provided on the lower part of the installation frame 1, and a second wedge block 96 is provided on both the front and rear sides of the top of the second pressing plate 97, and the inclined surface of the second wedge block 96 faces inward. When the second wedge block 96 moves downward, it squeezes the first wedge block 95 on the same side to slide inward.

[0047] After the first slider 51 is adjusted up and down to the adapted height, the first slider 51 may slide downward due to the gravity of the component itself, causing the puller 4 to deviate downward from the depressed area of ​​the vehicle body, thereby affecting the repair effect. To avoid this situation, the clamping sleeve 94 is initially engaged with the clamping block 92, so that the first slider 51 is fixed. When it is necessary to adjust the first slider 51 up and down, the maintenance personnel steps on the second pressing plate 97, and the second pressing plate 97 drives the second wedge block 96 to move downward, thereby driving the first wedge block 95 to slide inward, and then drives the clamping block 92 to slide inward, the third spring 93 is compressed, the clamping block 92 and the clamping sleeve 94 are no longer engaged, and the first slider 51 is released. After the first slider 51 moves up and down to the adapted height, the maintenance personnel releases the second pressing plate 97, and the third spring 93 is reset to drive the clamping block 92 to slide outward and re-clamp the clamping sleeve 94, so that the first slider 51 is fixed again, and the clamping block 92 pushes the first wedge block 95 to slide outward, and the first wedge block 95 drives the second pressing plate 97 to move downward through the second wedge block 96.

[0048] like Figure 1 , Figure 3 and Fig.13 As shown, a blocking mechanism 10 is also included, and the blocking mechanism 10 includes a second mounting frame 101, a second rotating shaft 102, a connecting rod 103, a threaded sleeve 104, a screw 105, a rubber block 106 and a third pressure plate 107. Two second mounting frames 101 are symmetrically fixed to the lower right side of the mounting frame 1. A second rotating shaft 102 is rotatably provided between the second mounting frames 101. The damping coefficient between the second rotating shaft 102 and the second mounting frame 101 is relatively large. Connecting rods 103 are provided on both sides of the front and rear of the second rotating shaft 102 by key connection. The connecting rods 103 are respectively located between the two second mounting frames 101 on the same side. Threaded sleeves 104 are provided on the tops of the connecting rods 103. Screws 105 are threadedly provided on the threaded sleeves 104. Rubber blocks 106 are provided on the tops of the screws 105. The friction coefficient of the rubber blocks 106 is relatively large. Third pressure plates 107 are provided on both ends of the second rotating shaft 102.

[0049] Since the puller 4 generates a reaction force acting to the right when pulling the sunken area of ​​the vehicle body to the left, the entire non-disassembly sheet metal repair equipment may move toward the direction close to the car, thereby affecting the sheet metal repair effect. For this reason, before starting the electric push rod 64, the maintenance personnel step on the third pressure plate 107 clockwise, and the third pressure plate 107 drives the connecting rod 103, the threaded sleeve 104, the screw 105 and the rubber block 106 to rotate to the lower right as a whole through the second rotating shaft 102, and then the rubber block 106 is adjusted by manually rotating the screw 105 so that the rubber block 106 contacts the ground. In this way, when the puller 4 pulls the vehicle body to the left, the blocking mechanism 10 as a whole plays a role similar to a door stopper, so that the entire non-disassembly sheet metal repair equipment can only move to the left and not to the right, thereby improving the automobile sheet metal repair effect.

[0050] like Figure 1 , Figure 3 and Fig.14 As shown, a cleaning mechanism 11 is also included, and the cleaning mechanism 11 includes a third mounting frame 111, a second articulated sleeve 112 and a brush head 113. The third mounting frame 111 is installed on both the front and rear sides of the right bottom of the second slider 62 by screws, and a second articulated sleeve 112 is hingedly provided between the lower right side of the third mounting frame 111, and a brush head 113 is provided at the bottom of the second articulated sleeve 112.

[0051] In order to ensure that the puller 4 and the car body can fit closely, it is necessary to scrape the dust from the concave part of the car body before the puller 4 operates. The maintenance personnel grasp the middle part of the second hinged sleeve 112 and drive the brush head 113 to swing back and forth, so that the brush head 113 can fully remove the dust from the concave area of ​​the car, further improving the repair effect of the car sheet metal.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
