Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, in particular to a leveling device for an aluminum vehicle body. Background Art

[0002] Aluminum car production lines are typically divided into multiple workstations, each responsible for a different processing or assembly task. Car bodies move along the production line to each station, undergoing different processing and assembly steps. The production line is designed for efficient assembly, ensuring that the car body can be assembled in a predetermined sequence through each step. The door installation sequence is to install the rear door first, then the front door, and finally, the door latches. After installation, the rear and front doors need to be suctioned flat against the car body. This not only facilitates the subsequent measurement of the door-to-body gap and the installation of the latches, but also prevents the doors from accidentally opening while the car body is moving along the production line.

[0003] Currently, the main method used to flatten the door onto the vehicle body is to use a device. For example, a device for detecting the adjacent surfaces of vehicle doors disclosed in the prior art (publication number CN220153428U, application date May 12, 2023) uses this device to flatten the door onto the vehicle body before testing. The flattening is achieved by attaching the suction cups at both ends of the connecting seat to the adjacent surfaces on both sides of the door inspection fixture, so that the leveling reference block fits on the two adjacent surfaces of the vehicle door. The operator can visually check whether the adjacent surfaces on both sides of the door joint fit with the leveling reference block to determine whether there is an error between the adjacent surfaces of the vehicle door. This device also has the following defects in actual use:

[0004] 1. The guide rod slides directly into the guide hole of the connector, causing the guide rod to wear the guide hole during use, thereby shortening the service life of the connector. When the guide hole is severely worn, the entire connector needs to be replaced, increasing the cost of the equipment.

[0005] 2. Relying solely on the suction cups at both ends of the connecting seat to suck the door flat on the outside can easily cause the gap between the door and the body to not meet the standard, which in turn causes the subsequent gap measurement to not meet the standard.

[0006] 3. Since the door moves with the car body after being sucked flat, it is easy to cause the tube connected to the vacuum pump to be affected or damaged. Damage to the tube will not only affect the suction effect, but may also cause equipment failure and affect the normal operation of the production line. Utility Model Content

[0007] The utility model aims to provide an aluminum vehicle body leveling device to solve the problem that the existing vehicle door leveling device only performs leveling on the outer side of the vehicle door, which may cause the gap between the vehicle door and the vehicle body to not meet the standard.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A suction leveling device for an aluminum vehicle body comprises an external suction leveling component and an internal block. The external suction leveling component comprises a body, suction cups are fixed on both sides of the body, air outlet holes are opened on the suction cups, one-way air outlet valves are installed at the air outlet holes, the suction cups are connected to a manual negative pressure mechanism, a suction leveling block is arranged under the body, an adjustment component for adjusting the distance between the suction leveling block and the body is connected between the suction leveling block and the body; the internal block comprises a magnet mounting seat, a magnet is fixed in the magnet mounting seat, a supporting screw is threadedly connected to the magnet mounting seat, the free end of the supporting screw is fixed with the supporting block, and the internal block is used to support between the inner side of the vehicle door and the vehicle body.

[0010] Preferably, as an improvement, the manual negative pressure mechanism is a manual vacuum pump or a manual negative pressure balloon.

[0011] Preferably, as an improvement, the adjustment assembly includes an adjustment screw vertically fixed on the suction block, the adjustment screw is passed through the body, a mounting hole is opened in the body, an adjustment nut is rotatably connected in the mounting hole, and the adjustment nut is threadedly connected to the adjustment screw.

[0012] Preferably, as an improvement, guide rods are vertically arranged on both sides of the adjusting screw, the bottom ends of the guide rods are fixed on the suction block, a guide hole is opened on the machine body, a bushing is detachably installed in the guide hole, and the top end of the guide rod is slidably connected in the bushing.

[0013] Preferably, as an improvement, the adjusting screw and the guide rod are both detachably connected to the suction block.

[0014] Preferably, as an improvement, the leveling block is a disc-shaped leveling block, and the adjustment component includes an adjusting screw, which is threadedly connected to the machine body, and the bottom end of the adjusting screw is fixedly connected to the leveling block.

[0015] Preferably, as an improvement, a handle is fixed on the body.

[0016] The principles and beneficial effects of this program are:

[0017] 1. This solution uses an external suction leveling component and an internal block to level the car door. Compared with the existing technology that only leveled the car door on the outside of the car door, the leveling effect is better, and it can better ensure that the gap between the car door and the car body meets the standard, avoiding the problem of subsequent gap measurement not meeting the standard. Taking the rear door leveling as an example, in actual use, the two suction cups of the external suction leveling component are respectively attached to the outer surface of the car door and the car body, and the position of the suction leveling block is adjusted so that it is pressed against the connection between the car door and the car body; on the inside, the magnet of the internal block is attached to the car body, and the length of the support screw is adjusted to support and press against the inner side of the car door, thereby providing support for the car door on the inside. The external suction leveling component leveled the car door on the outside, while the internal block cooperates with the external suction leveling component to support the car door on the inside, which can improve the leveling effect of the car door and increase the rate of compliance with the standard for the gap between the car door and the car body.

[0018] 2. When using manual negative pressure mechanisms such as manual vacuum pumps and manual negative pressure balloons, there is no need to connect to the negative pressure source through a negative pressure pipe, so that this solution can be used along with the vehicle body throughout the entire production line without being restricted by the length of the pipe and the location of the air source, and there is no need to worry about possible leakage due to damage to the pipe caused by pulling.

[0019] 3. This solution provides two types of adjustment components for the leveling block. One type is directly connected to the machine body through a threaded adjustment screw. The adjustment screw is rotated to drive the leveling block to move in the thickness direction of the machine body, thereby adjusting the distance between the leveling block and the machine body. The advantage of this adjustment component is its simple structure. The other adjustment component is to insert the adjustment screw into the machine body and thread it with an adjustment nut that is rotatably connected to the machine body. The adjustment screw is driven to move by turning the adjustment nut. The advantage of this adjustment component is that there is no need to set a threaded hole on the machine body to match the adjustment screw, avoiding the situation where the entire machine body needs to be replaced due to thread wear caused by increased use time. In this adjustment component, if the thread is damaged, only the adjustment screw or the adjustment nut needs to be replaced, without replacing the entire machine body. Overall, it is more cost-effective to install the equipment.

[0020] Furthermore, the latter adjustment assembly is equipped with two guide rods to guide the leveling block, effectively improving the stability of the leveling movement. Furthermore, this solution incorporates removable bushings within the guide holes, into which the guide rods slide, preventing direct engagement between the guide rods and the machine body. This effectively reduces wear and tear on the machine body, extending its service life. If the bushings become severely worn, only the bushings need to be replaced, eliminating the need to replace the entire machine body, further reducing equipment costs.

[0021] 4. The adjusting screw and guide rod are detachably connected to the suction block, making it easy to replace damaged adjusting screws and guide rods. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is further described in detail through specific implementation methods:

[0028] The figure marks in the drawings of the specification include: body 1, handle 11, guide hole 12, bushing 13, mounting hole 2, adjusting nut 21, adjusting screw 22, guide rod 23, suction block 3, suction cup 4, manual vacuum pump 5, built-in block 6, magnet mounting seat 61, magnet 62, support screw 63, support block 64, manual negative pressure balloon 7, car door 8, car body 9, external suction assembly 10.

[0029] Example 1:

[0030] An aluminum vehicle body leveling device, comprising Figure 1 The outer suction leveling assembly 10 shown and Figure 2 As shown in the built-in block 6. Figure 1 As shown, the external suction leveling assembly 10 includes a body 1, a handle 11 screwed to the top of the body 1, and suction cups 4 bolted to the left and right sides of the body 1. The suction cups 4 have air outlet holes (not shown) and one-way air outlet valves installed at the air outlet holes. The suction cups 4 are connected to a manual negative pressure mechanism. In this embodiment, the manual negative pressure mechanism is a manual vacuum pump 5, such as a manual pull-type negative pressure pump in the prior art.

[0031] A leveling block 3 is disposed beneath the body 1. An adjustment assembly for adjusting the distance between the leveling block 3 and the body 1 is connected between the leveling block 3 and the body 1. The adjustment assembly includes a vertical adjustment screw 22, the bottom end of which is bolted to the leveling block 3. The adjustment screw 22 extends vertically through the body 1. A mounting hole 2 is defined within the body 1, within which an adjustment nut 21 is rotatably mounted. The adjustment nut 21 is threadedly connected to the adjustment screw 22. Guide rods 23 are vertically disposed on either side of the adjustment screw 22. The bottom ends of the guide rods 23 are bolted to the leveling block 3. A guide hole 12 is defined within the body 1. A bushing 13 is removably bolted into the guide hole 12. The top ends of the guide rods 23 slideably engage within the bushing 13.

[0032] Combine Figure 2 and Figure 3 As shown, the built-in block 6 includes a magnet mounting seat 61, a magnet 62 is fixed at the bottom of the magnet mounting seat 61, a support screw 63 is threadedly connected to the magnet mounting seat 61, and a support block 64 is fixed to the free end of the support screw 63 by screws. The built-in block 6 is used to be supported between the inner side of the vehicle door 8 and the vehicle body 9.

[0033] The working principle of an aluminum body leveling device is as follows:

[0034] In this embodiment, the rear door 8 is taken as an example. After the rear door 8 is installed, the door 8 is opened to adsorb the magnet 62 on the built-in block 6 on the vehicle body 9. The supporting screw 63 is rotated to adjust the length of the supporting block 64 extending out of the magnet mounting seat 61 to ensure that the supporting block 64 can be tightly pressed against the inner side of the door 8 after the door 8 is closed. Figure 3 By supporting the inner block 6 between the vehicle body 9 and the inner side of the door 8, the door 8 can be supported from the inner side, thereby better sucking the door 8 flat. In actual use, a flexible structure such as a rubber layer, a silicone layer, or a sponge layer is added to the surface of the support block 64 to prevent hard contact and wear on the door.

[0035] Combine Figure 4 As shown, the suction block 3 is pressed against the joint between the door 8 and the body 9, and the two suction cups 4 of the external suction assembly 10 are respectively sucked onto the door 8 and the body 9. Then, the adjusting nut 21 is rotated to drive the adjusting screw 22 to move along the thickness direction of the body 1, thereby adjusting the distance between the suction block 3 and the body 1, so that the door 8 and the body 9 are against the suction block 3, thereby completing the suction leveling of the door 8.

[0036] In this embodiment, the vehicle door 8 is sucked flat on the outer side surface by the external suction component 10, and the built-in block 6 is used to support between the inner side surface of the vehicle door 8 and the vehicle body 9, thereby supporting the vehicle door 8 on the inner side. Combined with the suction of the external suction component 10 on the outer side surface, the suction effect of the vehicle door 8 can be improved, and the compliance rate of the gap between the vehicle door 8 and the vehicle body 9 can be improved.

[0037] Example 2:

[0038] Combine Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the manual negative pressure mechanism is a manual negative pressure balloon 7, the suction block 3 is a disc-shaped suction block 3, the adjustment component only includes an adjusting screw 22, and does not include a guide rod 23. The adjusting screw 22 is directly threadedly connected to the body 1, and the bottom end of the adjusting screw 22 is fixedly connected to the suction block 3 with a bolt.

[0039] In actual use, simply rotating the adjustment screw 22 can drive the leveling block 3 to move in the thickness direction of the machine body 1, thereby completing the adjustment of the leveling block 3. This has a simple structure and is easy to operate. In other embodiments, the bottom end of the adjustment screw 22 can be rotatably connected to the leveling block 3, so that the leveling block 3 does not rotate when the adjustment screw 22 is rotated.
