Description

Technical Field

[0001] This invention relates to the field of automotive door inspection and leveling technology, specifically providing a leveling fixture. Background Technology

[0002] In the automobile manufacturing process, the leveling of the four doors is an essential step in monitoring the gap and flatness between the car body and the four doors. This requires door matching tests on the car body. First, the flatness control reference points of the front and rear doors and the flatness control reference points of the rear door and the car body are leveled. Then, the matching degree between the edges of the front and rear doors and the edges of the rear doors and the edges of the car body is tested.

[0003] Currently, the mainstream method for leveling the four doors of an all-aluminum car body-in-white is to use vacuum suction cups to level the rear door with the side panel of the car body and the front door with the rear door. This type of vacuum suction cup tooling is expensive, involves many adjustment steps, and is inconvenient to operate. Furthermore, when measuring the gap and flatness between the car body-in-white and the four doors using a three-coordinate laser radar, the suction cup is prone to failure during rotation, and the relative positions of the front and rear doors with the car body-in-white will change, resulting in distorted measurement results.

[0004] Therefore, in the field of measurement, there is a need for a leveling fixture that is easy to operate, inexpensive, highly accurate, highly compatible, and highly practical. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems of complex operation, low precision and low practicality of existing leveling fixtures.

[0006] The present invention provides a leveling fixture, which includes: a fixing mechanism fixedly disposed on a first mounting member; and a movable mechanism fixedly disposed on a second mounting member. When the first mounting member and the second mounting member are in a mating state, the fixing mechanism and the movable mechanism can be connected to each other by magnetic attraction, and the leveling between the first mounting member and the second mounting member can be achieved by adjusting the fixing mechanism.

[0007] With the above technical solution, the leveling fixture of the present invention is fixed to the vehicle body by a fixed mechanism and fixed to the door by a movable mechanism. The fixed mechanism and the movable mechanism are connected to each other by magnetic attraction, so that the position of the door and the vehicle body is kept fixed. At the same time, the relative position of the door and the vehicle body can be leveled by adjusting the fixed mechanism. This solves the problem of suction cup failure during rotation. The structure is simple, the operation is simple and reliable, it can adapt to the actual field work needs, and it is convenient for subsequent measurement and data collection.

[0008] In a specific embodiment of the above-mentioned leveling fixture, the fixing mechanism includes a first base and an adjusting component. The first base is configured to be fixed on the first mounting component. The adjusting component includes an adjusting member, an adjusting shaft, and a positioning block. The positioning block is configured to be magnetically connected to the movable mechanism. The adjusting member is rotatably but non-slidingly disposed within the first base. The adjusting shaft is slidably but non-rotatably disposed within the first base. One end of the adjusting shaft is threadedly connected to the adjusting member, and the other end of the adjusting shaft is connected to the positioning block. By rotating the adjusting member, the adjusting shaft can be slid relative to the first base, thereby adjusting the distance between the first base and the positioning block, and thus achieving leveling between the first mounting component and the second mounting component.

[0009] When the above technical solution is adopted, the adjusting shaft can be driven to slide laterally relative to the first base by rotating the adjusting component, so as to push the positioning block laterally, so that the positioning block moves closer to or away from the first base, thereby adjusting the relative distance between the first base and the positioning block, and thus achieving the leveling between the first mounting component and the second mounting component. The operation is simple and the practicality is high.

[0010] In a specific embodiment of the leveling fixture described above, the adjusting component further includes a first magnetic element, which is fixedly disposed on the positioning block.

[0011] In a specific embodiment of the leveling fixture described above, the adjusting assembly further includes a first limiting member and a first bushing. The first limiting member is fixedly disposed on the first base so that the adjusting member can be rotatably disposed within the first base, and the adjusting shaft is slidably disposed within the first bushing, which is fixedly disposed within the first base.

[0012] In a specific embodiment of the leveling fixture described above, the fixing mechanism further includes a clamping assembly. The clamping assembly includes a clamping member, a clamping shaft, and a blocking block. The clamping member is rotatably but non-slidingly disposed within the first base. The clamping shaft is slidingly but non-rotatably disposed within the first base. The clamping shaft is threadedly connected to the clamping member. The blocking block is fixedly disposed on the first base. A clamping space is formed between the clamping shaft and the blocking block, so that the first mounting member can be placed within the clamping space, thereby fixing the first base onto the first mounting member.

[0013] When the above technical solution is adopted, the clamping shaft can be driven to slide laterally relative to the first base by rotating the clamping component, so that the clamping shaft moves away from or closer to the blocking block, thereby opening or closing the clamping space between the clamping shaft and the blocking block, thus realizing the assembly and disassembly of the fixing mechanism on the first mounting part. This structure is fixed by thread clamping, which is simple to operate, easy to assemble and disassemble, improves leveling efficiency, and has strong versatility and wide applicability.

[0014] In a specific embodiment of the above-mentioned leveling fixture, the clamping assembly further includes a second limiting member and a second bushing. The second limiting member is fixedly disposed on the first base so that the clamping member can be rotatably disposed within the first base, and the clamping shaft can be slidably disposed within the second bushing, which is fixedly disposed within the first base.

[0015] In a specific embodiment of the above-mentioned leveling fixture, the movable mechanism includes a second base, an elastic member, and a snap-fit ​​member. The second base is configured to be magnetically attracted to the fixing mechanism. A groove is provided inside the second base. The snap-fit ​​member is slidably disposed in the groove. The elastic member is disposed in the groove, and both ends of the elastic member abut against the snap-fit ​​member and the inner wall of the groove, respectively. The second base is also provided with a snap-fit ​​interface communicating with the groove. The snap-fit ​​member can pass through the snap-fit ​​interface and slide relative to it to clamp the second mounting member, thereby fixing the movable mechanism on the second mounting member.

[0016] When the above technical solution is adopted, the snap-fit ​​component is pressed and snapped onto the second mounting component for fixation. This snap-fit ​​method is simple to operate, easy to disassemble and assemble, improves leveling efficiency, and has strong versatility and wide applicability.

[0017] In a specific embodiment of the leveling fixture described above, the snap-fit ​​component includes a sliding part and a snap-fit ​​part that are connected to each other. The sliding part is slidably disposed in the groove and abuts against the elastic member. The snap-fit ​​part can pass through the snap-fit ​​interface and slide relative to it.

[0018] In a specific embodiment of the leveling fixture described above, the movable mechanism further includes a second magnetic component, which is fixedly mounted on the second base.

[0019] In the specific implementation of the above-mentioned leveling fixture, the first mounting component is the vehicle body, and the second mounting component is the vehicle door. Attached Figure Description

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although this application describes the leveling between the body-in-white of an automobile and its four doors, the technical solution of the present invention is not limited thereto. This leveling fixture can obviously also be applied to other equipment besides automobiles, and such changes do not depart from the principles and scope of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0031] It should be noted that in the description of this invention, terms such as "inner," "left," and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the relevant device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Reference Figures 1-7 A specific preferred embodiment of the present invention will be described below.

[0034] First refer to Figures 1-3 This figure is a schematic diagram of the installation structure of the leveling fixture of the present invention. Figures 1-3 As shown, the leveling fixture includes: a fixing mechanism 1, which is fixedly mounted on a first mounting component; and a movable mechanism 2, which is fixedly mounted on a second mounting component. The first mounting component is the vehicle body 3, and the second mounting component is the vehicle door 4. When the first and second mounting components are engaged, i.e., when the vehicle door 4 is closed, the fixing mechanism 1 and the movable mechanism 2 can be connected to each other via magnetic attraction to fix the vehicle door 4. Adjusting the fixing mechanism 1 allows for leveling of the relative position of the vehicle door 4 and the vehicle body 3.

[0035] Then refer to Figure 4 and Figure 5 This figure is a schematic diagram of the fixing mechanism 1 of the present invention. Figure 4 and Figure 5 As shown, the fixing mechanism 1 includes a first base 11, an adjustment component 12, and a pressing component 13, with the adjustment component 12 and the pressing component 13 respectively disposed on the first base 11. The fixing mechanism 1 is fixedly mounted on the vehicle body 3 via the pressing component 13, and is magnetically connected to the movable mechanism 2 via the adjustment component 12. Adjusting the adjustment component 12 allows for leveling of the relative position of the door 4 and the vehicle body 3.

[0036] Continue as Figure 4 and Figure 5As shown, the adjustment assembly 12 includes an adjustment member 121, an adjustment shaft 122, a positioning block 123, a first limiting member 124, a first bushing 125, and a first magnetic element 126. A first through hole (not shown) is provided on the first base 11. The adjustment member 121 extends into the first through hole through one side of the first base 11 and is threadedly connected to one end of the adjustment shaft 122. The adjustment shaft 122 is slidably but non-rotatably disposed in the first bushing 125. The first bushing 125 is fixedly disposed in the first through hole. The other end of the adjustment shaft 122 extends out of the first through hole and is connected to the positioning block 123. The positioning block 123 is disposed on the other side of the first base 11. The first magnetic element 126 is detachably fixedly disposed on the outside of the positioning block 123. The first magnetic element 126 can be magnetically connected to the movable mechanism 2. The first limiting member 124 is fixedly disposed on one side of the first base 11 and can limit the adjustment member 121, so that the adjustment member 121 is rotatably but non-slidably disposed in the first through hole. For example, the adjusting member 121 is an adjusting bolt, the first bushing 125 is a D-type bushing, and the first magnetic member 126 is a magnet.

[0037] In the above structure, rotating the adjusting member 121 can drive the adjusting shaft 122 to slide laterally relative to the first base 11, thereby laterally pushing the positioning block 123 and causing the positioning block 123 to move closer to or further away from the first base 11, thus adjusting the relative distance between the first base 11 and the positioning block 123. Specifically, the fixing mechanism 1 is first fixedly installed on the vehicle body 3, and the movable mechanism 2 is fixedly installed on the door 4. When the door 4 is closed, the fixing mechanism 1 is magnetically fixed to the movable mechanism 2 by the magnet on the positioning block 123. By rotating the adjusting bolt clockwise or counterclockwise, the positioning block 123 pulls or pushes the movable mechanism 2, thereby achieving the leveling of the relative position between the door 4 and the vehicle body 3.

[0038] It should be noted that although the above description refers to the first magnetic element 126 being fixedly disposed on the positioning block 123 to achieve magnetic connection with the movable mechanism 2, this is not a limitation. Those skilled in the art can omit the first magnetic element 126 as needed and directly set the positioning block 123 to a material that can be magnetically connected with the movable mechanism 2. Of course, considering tooling costs and ease of replacement, it is preferable that the first magnetic element 126 is detachably fixedly disposed on the positioning block 123.

[0039] Continue as Figure 4 and Figure 5As shown, the clamping assembly 13 includes a clamping member 131, a clamping shaft 132, a blocking block 133, a second limiting member 134, and a second bushing 135. A second through hole (not shown) is also provided on the first base 11. The clamping member 131 extends into the second through hole from one side of the first base 11 and is threadedly connected to the clamping shaft 132. The clamping shaft 132 is slidably but non-rotatably disposed within the second bushing 135. The second bushing 135 is fixedly disposed within the second through hole. The blocking block 133 is fixedly disposed at the extension end on the other side of the first base 11, creating a clamping space between the clamping shaft 132 and the blocking block 133. The second limiting member 134 is fixedly disposed on one side of the first base 11, limiting the clamping member 131 so that it is rotatably but non-slidably disposed within the second through hole. For example, the clamping member 131 is a clamping bolt, and the second bushing 135 is a D-type bushing.

[0040] In the above structure, rotating the clamping member 131 can drive the clamping shaft 132 to slide laterally relative to the first base 11, causing the clamping shaft 132 to move away from or closer to the blocking block 133, thereby opening or closing the clamping space between the clamping shaft 132 and the blocking block 133. Specifically, first, the clamping bolt is rotated counterclockwise to open the clamping space between the clamping shaft 132 and the blocking block 133, and the fixing mechanism 1 is clamped at the door opening stop position in the lock area of ​​the door 4. Then, the clamping bolt is rotated clockwise to close the clamping space between the clamping shaft 132 and the blocking block 133, thereby fixing the fixing mechanism 1 on the door 4.

[0041] Furthermore, continue as Figure 4 and Figure 5 As shown, since the fixing mechanism 1 is fixedly installed on the vehicle body 3 by clamping with the clamping shaft 132 and the blocking block 133, a non-metallic gasket 136 is provided on the inner side of the clamping shaft 132 and the blocking block 133, that is, on the end face that can contact the vehicle body 3, to avoid rigid contact between the clamping shaft 132 and the blocking block 133 and the two sides of the vehicle body 3, thus protecting the vehicle body 3 and preventing wear. The non-metallic gasket 136 can be a nylon gasket, a rubber gasket, etc.

[0042] The following reference Figure 6 and Figure 7 This figure is a schematic diagram of the structure of the active mechanism 2 of the present invention. Figure 6 and Figure 7As shown, the movable mechanism 2 includes a second base 21, an elastic member 22, and a snap-fit ​​member 23. A groove 211 is provided within the second base 21. The snap-fit ​​member 23 is slidably disposed within the groove 211. The elastic member 22 is disposed within the groove 211, with both ends of the elastic member 22 abutting against the snap-fit ​​member 23 and the inner wall of the groove 211, respectively. A snap-fit ​​interface 212 communicating with the groove 211 is also provided on the second base 21. The snap-fit ​​member 23 can pass through the snap-fit ​​interface 212 and slide relative to it to clamp the second mounting member, thereby fixing the movable mechanism 2 onto the second mounting member. Two sets of snap-fit ​​members 23 and elastic members 22 are provided, located on the left and right sides of the second base 21, respectively. Each set of elastic members 22 has two members, with both ends of the two elastic members abutting against the inner wall of the groove 211 and the end face of the snap-fit ​​member 23 located within the groove 211, respectively. Among them, the elastic component 22 is a spring.

[0043] Specifically, by pressing the locking members 23 on the left and right sides of the second base 21 with your hand, the elastic member 22 is compressed, and the locking members 23 on both sides slide towards each other and make contact, thus locking the movable mechanism 2 at the opening position of the door lock on the inner panel of the car door 4. Then, by releasing your hand, the locking members 23 on both sides are locked and fixed on the car door 4.

[0044] Furthermore, each set of snap-fit ​​components 23 includes a sliding part 231 and a snap-fit ​​part 232 connected to each other. The sliding part 231 is slidably disposed in the slide groove 211 and abuts against the elastic member 22. The snap-fit ​​part 232 passes through the snap-fit ​​interface 212 and extends outward in a bent shape, and the snap-fit ​​part 232 can slide relative to the snap-fit ​​interface 212. When the snap-fit ​​component 23 is pressed, the sliding part 231 slides in the slide groove 211 and drives the snap-fit ​​part 232 to slide at the snap-fit ​​interface 212. When the snap-fit ​​component 23 is snapped and fixed on the door 4, the snap-fit ​​part 232 and the opening end face of the door lock on the inner panel of the door 4 form a mutually restraining force under the action of the elastic member 22, so as to achieve the snap-fit ​​and fixing function.

[0045] Furthermore, the movable mechanism 2 also includes a second magnetic element 24, which is fixedly mounted on the second base 21. The second magnetic element 24 can be magnetically connected to the fixing mechanism 1, and is detachably fixed on the side opposite to the snap-fit ​​interface 212. The second magnetic element 24 is a magnetic cover plate.

[0046] It should be noted that although the above description refers to the second magnetic element 24 being fixedly mounted on the second base 21 to achieve magnetic connection with the fixing mechanism 1, this is not a limitation. Those skilled in the art can omit the second magnetic element 24 as needed and directly set the second base 21 to a material that can be magnetically connected with the fixing mechanism 1. Of course, considering tooling costs and ease of replacement, it is preferable that the second magnetic element 24 is detachably fixedly mounted on the second base 21.

[0047] The following is combined with Figures 1-7 The operation steps of the leveling tool of the present invention are described in detail.

[0048] Step 1: Fix the fixing mechanism 1 to the vehicle body 3. Specifically, first rotate the clamping bolt counterclockwise to open the clamping space between the clamping shaft 132 and the blocking block 133, and clamp the fixing mechanism 1 at the door opening stop position in the lock area of ​​the door 4. Then rotate the clamping bolt clockwise to close the clamping space between the clamping shaft 132 and the blocking block 133, so as to fix the fixing mechanism 1 to the vehicle body 3.

[0049] Step 2: Securely install the movable mechanism 2 onto the car door 4. Specifically, by pressing the locking members 23 on the left and right sides of the second base 21 with your hand, the elastic member 22 is compressed, and the locking members 23 on both sides slide towards each other and make contact, thus locking the movable mechanism 2 into the opening position of the door lock on the inner panel of the car door 4. Then, release your hand, and the locking members 23 on both sides will be locked and fixed onto the car door 4.

[0050] Step 3: Close the car door 4. The fixing mechanism 1 and the moving mechanism 2 are magnetically connected, keeping the car door 4 and the car body 3 in a fixed position. Specifically, the first magnetic component 126 on the fixing mechanism 1 and the second magnetic component 24 on the moving mechanism 2 are magnetically attracted to each other, thus connecting the two mechanisms.

[0051] Step 4: Adjust the fixing mechanism 1 to level the relative position of the door 4 and the body 3. Specifically, first, fix the fixing mechanism 1 to the body 3, and fix the movable mechanism 2 to the door 4. When the door 4 is closed, the fixing mechanism 1 is magnetically fixed to the movable mechanism 2 by the magnet on the positioning block 123. By rotating the adjusting bolt clockwise or counterclockwise, the positioning block 123 pulls or pushes the movable mechanism 2, thereby achieving the leveling of the relative position of the door 4 and the body 3.

[0052] The above-described embodiments and various extended embodiments of the present invention employ a fixed mechanism 1 fixed to the vehicle body 3 and a movable mechanism 2 fixed to the vehicle door 4. The fixed mechanism 1 and the movable mechanism 2 are connected to each other through magnetic attraction, so that the position of the vehicle door 4 and the vehicle body 3 remains fixed. At the same time, the relative position of the vehicle door 4 and the vehicle body 3 can be leveled by adjusting the fixed mechanism 1. This solves the problem of suction cup failure during rotation. The structure is simple, the operation is simple and reliable, it can adapt to the actual field work requirements, and it is convenient for subsequent measurement and data collection.

[0053] In addition, the fixing mechanism 1 is fixed by threaded clamping, and the moving mechanism 2 is fixed by snap-fitting. It is simple to operate, easy to disassemble and assemble, improves leveling efficiency, and has strong versatility and wide applicability.

[0054] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
