[0002] In automotive painting workshops, automated spraying technology is being used more and more widely to improve efficiency, stabilize quality, and reduce pollution, especially for spraying components such as car door inner panels. However, traditional fixtures are difficult to guarantee the fixed opening of the car door, which poses a challenge to the normal operation of the robot spraying program, causing the robot program to fail to operate normally. Utility Model Content

[0003] The main purpose of this utility model is to propose a door opening fixing clamp, which aims to solve the problem of how to keep the door opening at a fixed degree.

[0004] To achieve the above objectives, this utility model proposes a door opening fixing clamp for adjusting the opening between a vehicle door and its frame. The door opening fixing clamp includes a mounting bracket, a sliding column, an elastic limiting component, a first fastener, and a second fastener. The mounting bracket includes a bracket body, a first sliding shaft, and a second sliding shaft. The bracket body is connected to the vehicle door via the first fastener, and the sliding column is connected to the door frame via the second fastener. Both the first and second sliding shafts are movably mounted on the bracket body. The first and second sliding shafts are arranged along a first direction. Both sliding shafts are connected to the elastic limiting component, so that the elastic limiting component can drive the first sliding shaft and the second sliding shaft to move closer to each other and abut against the two sides of the sliding column respectively. The sliding column is provided with a first limiting groove. When the car door moves away from the door frame, the car door can drive the first sliding shaft and the second sliding shaft to move relative to the sliding column until the first sliding shaft moves into the first limiting groove. The first limiting groove can restrict the movement of the first sliding shaft located in the first limiting groove relative to the sliding column to restrict the car door from continuing to move away from the door frame.

[0005] In one embodiment, the frame body includes a first clamping plate and a second clamping plate. The first clamping plate is connected to the vehicle door via a first fastener. The first clamping plate and the second clamping plate are spaced apart along the axial direction of the first sliding shaft. The first clamping plate is provided with a first sliding groove and a second sliding groove, and the second clamping plate is provided with a third sliding groove and a fourth sliding groove.

The first clamping plate, the second clamping plate, the first abutting portion, and the second abutting portion form the limiting hole. The two ends of the first abutting portion are respectively engaged with the first clamping plate. The first sliding shaft and the second clamping plate abut against each other to restrict the movement of the first sliding shaft relative to the frame body. The two ends of the second abutting part abut against the first clamping plate and the second clamping plate respectively to restrict the movement of the second sliding shaft relative to the frame body. The first shaft body and the second shaft body are both connected to the elastic limiting component so that the elastic limiting component can drive the first abutting part and the second abutting part to move closer to each other and abut against the two sides of the sliding column respectively. The door moves away from the door frame. The door can drive the first abutting part and the second abutting part to move relative to the sliding column until the first abutting part moves into the first limiting groove. The first limiting groove can restrict the movement of the first abutting part located in the first limiting groove relative to the sliding column to restrict the door from continuing to move away from the door frame.

[0007] In one embodiment, the first clamping plate includes a plate body and a mounting plate. The mounting plate is connected to the vehicle door via a first fastener. Both the plate body and the second clamping plate are connected to the mounting plate, and the plate body and the second clamping plate are spaced apart along the axial direction of the first sliding shaft. The plate body is provided with a first sliding groove and a second sliding groove. The plate body, the second clamping plate, the first abutting part, and the second abutting part form the limiting hole. The mounting plate is provided with a threaded hole. The first fastener includes a first bolt. The first bolt passes through a first mounting hole on the vehicle door and is threaded into the threaded hole. The mounting plate is provided with a through hole for the sliding column to pass through.

[0008] In one embodiment, a first opening is provided at the end of the first groove away from the second groove;

[0009] And / or,

[0010] The second groove has a second opening at the end furthest from the first groove;

[0011] And / or,

[0012] The third slide groove has a third opening at the end away from the fourth slide groove;

[0013] And / or,

[0014] The fourth groove has a fourth opening at the end furthest from the third groove.

[0015] In one embodiment, the elastic limiting component includes a first elastic limiting member and a second elastic limiting member. The first elastic limiting member and the second elastic limiting member are spaced apart along the axial direction of the first sliding shaft, and the first elastic limiting member and the second elastic limiting member are respectively disposed on two opposite sides of the sliding column. The first sliding shaft and the second sliding shaft are both connected to the first elastic limiting member, and the first sliding shaft and the second sliding shaft are both connected to the second elastic limiting member.

[0016] In one embodiment, the first sliding shaft is provided with a first groove and a second groove, the second sliding shaft is provided with a third groove and a fourth groove, the two ends of the first elastic limiting member are respectively located in the first groove and the third groove, and the two ends of the second elastic limiting member are respectively located in the second groove and the fourth groove.

[0017] In one embodiment, the first elastic limiting member includes a first spring;

[0018] And / or,

[0019] The second elastic limiting member includes a second spring.

[0020] In one embodiment, the sliding column includes a column body and a connector. The connector is rotatably mounted on the column body and has a through hole. The second fastener includes a second bolt and a nut. The second bolt passes through the through hole and a second mounting hole on the door frame and is threadedly connected to the nut. The elastic limiting component can drive the first sliding shaft and the second sliding shaft to move closer to each other and abut against the two sides of the column body that are opposite to each other. The column body has a first limiting groove.

[0021] In one embodiment, the first limiting groove includes a first slot and a second slot, which are spaced apart along the axial direction of the slide column.

[0022] In this embodiment of the utility model, the first direction is the front-to-back direction. The frame body is connected to the car door via a first fastener, and the sliding column is connected to the door frame via a second fastener. This ensures that the car door opening fixing clamp can be stably fixed to the car door and door frame, providing stable support for maintaining a fixed opening of the car door. The elastic limiting component connects the first sliding shaft and the second sliding shaft, allowing them to approach each other and abut against the two sides of the sliding column that are arranged opposite each other in the front-to-back direction. This design allows the car door opening fixing clamp to automatically adjust the position of the first and second sliding shafts relative to the sliding column according to the opening of the car door, thereby maintaining the smoothness of the car door opening. The sliding column is provided with a first limiting groove. When the car door moves away... When moving away from the door frame, the first and second sliding shafts move relative to the sliding column until the first sliding shaft moves into the first limiting groove. The first limiting groove restricts the first sliding shaft from moving further relative to the sliding column, thereby limiting the door from moving further away from the door frame and ensuring that the door can maintain a fixed opening. The door opening fixing fixture allows for different first limiting grooves to adapt to different vehicle models and different opening requirements, improving the versatility and flexibility of the door opening fixing fixture. When it is necessary to change the door opening or close the door, manually operate the door to move away from or closer to the door frame. The door can drive the first sliding shaft to slide out of the first limiting groove, thereby changing the door opening or closing the door. This embodiment of the invention provides a first limiting groove on the sliding column, allowing the first sliding shaft to slide relative to the sliding column into the first limiting groove. The first limiting groove restricts the first sliding shaft from moving further relative to the sliding column, thereby limiting the door from moving further away from the door frame. This allows for precise adjustment and fixing of the opening between the door and the door frame, ensuring that the door maintains a fixed opening on the painting production line. Robots can more accurately identify the painting area, resulting in a more uniform painting effect, reducing inconsistent coating thickness, improving the uniformity and consistency of the painting, significantly reducing rework rates, and improving product quality. Furthermore, by using a door opening fixing fixture, the need for manual adjustment of the door opening is reduced, increasing automation and simplifying the operation process of fixing and adjusting the door opening. Employees can quickly set the door opening, reducing operational complexity, thereby accelerating the production process and improving overall production efficiency. Attached Figure Description

[0033] In automotive painting workshops, automated spraying technology is being used more and more widely to improve efficiency, stabilize quality, and reduce pollution, especially for spraying components such as car door inner panels. However, traditional fixtures are difficult to guarantee the fixed opening of the car door, which poses a challenge to the normal operation of the robot spraying program, causing the robot program to fail to operate normally.

[0034] After careful investigation, the applicant discovered that because traditional fixtures cannot guarantee a fixed opening degree for the car doors, the opening degree of the car doors is inconsistent each time during the assembly line painting operation. The robot cannot accurately identify the painting area, and the robot may cause uneven painting or omission of some areas due to the unstable opening degree of the car doors, which affects the painting quality, increases the rework rate, reduces production efficiency, and seriously affects the normal operation of the robot program.

[0035] The main purpose of this utility model is to propose a door opening fixing clamp to solve the problem of how to keep the door opening at a fixed angle.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, the door opening fixing clamp 100 is used to adjust the opening between the vehicle door and the door frame. The door opening fixing clamp 100 includes a mounting bracket 1, a sliding column 2, an elastic limiting component 3, a first fastener (not shown) and a second fastener (not shown). The mounting bracket 1 includes a bracket body 11, a first sliding shaft 12 and a second sliding shaft 13. The bracket body 11 is connected to the vehicle door through the first fastener, and the sliding column 2 is connected to the door frame through the second fastener. The first sliding shaft 12 and the second sliding shaft 13 are movably mounted on the bracket body 11. The first sliding shaft 12 and the second sliding shaft 13 are arranged along a first direction. The first sliding shaft 12 and the second sliding shaft 13 are both connected to the elastic limiting component 3, so that the elastic limiting component 3 can drive the first sliding shaft 12 and the second sliding shaft 13 to move closer to each other and abut against the two sides of the sliding column 2 respectively. The sliding column 2 is provided with a first limiting groove 211. When the door moves away from the door frame, the door can drive the first sliding shaft 12 and the second sliding shaft 13 to move relative to the sliding column 2 until the first sliding shaft 12 moves into the first limiting groove 211. The first limiting groove 211 can restrict the movement of the first sliding shaft 12 relative to the sliding column 2 within the first limiting groove 211 to restrict the door from continuing to move away from the door frame.

[0037] In this embodiment of the utility model, the first direction is the front-to-back direction. The frame body 11 is connected to the car door through a first fastener, and the sliding column 2 is connected to the door frame through a second fastener, thereby ensuring that the car door opening fixing clamp 100 can be stably fixed on the car door and the door frame, providing stable support for the car door to maintain a fixed opening. The elastic limiting component 3 connects the first sliding shaft 12 and the second sliding shaft 13, so that they can approach each other and abut against the two sides of the sliding column 2 that are arranged opposite each other in the front-to-back direction. This design allows the car door opening fixing clamp 100 to automatically adjust the position of the first sliding shaft 12 and the second sliding shaft 13 relative to the sliding column 2 according to the opening of the car door, thereby maintaining the smoothness of the car door opening. The sliding column 2 is provided with a first limiting groove 211, which is used when the car door moves away from the door frame. When the door moves in the direction of the sliding column 2, the first sliding shaft 12 and the second sliding shaft 13 will move relative to the sliding column 2 until the first sliding shaft 12 moves into the first limiting groove 211. The first limiting groove 211 restricts the first sliding shaft 12 from continuing to move relative to the sliding column 2, thereby restricting the door from moving further away from the door frame and ensuring that the door can maintain a fixed opening. The door opening fixing clamp 100 allows different first limiting grooves 211 to adapt to the needs of different models and different openings, improving the versatility and flexibility of the door opening fixing clamp 100. When it is necessary to change the door opening or close the door, the door can be manually moved away from or closer to the door frame. The door can drive the first sliding shaft 12 to slide out of the first limiting groove 211, thereby changing the door opening or closing the door.

[0038] The technical solution of this utility model provides a first limiting groove 211 on the sliding column 2, allowing the first sliding shaft 12 to slide relative to the sliding column 2 into the first limiting groove 211. The first limiting groove 211 restricts the first sliding shaft 12 from moving further relative to the sliding column 2, thereby limiting the door from moving further away from the door frame. This allows for precise adjustment and fixation of the opening between the door and the door frame, ensuring that the door maintains a fixed opening on the painting production line. The robot can more accurately identify the painting area, thereby achieving a more uniform painting effect, reducing the problem of inconsistent coating thickness, improving the uniformity and consistency of the painting, significantly reducing rework rate, and improving product quality. By using the door opening fixing fixture 100, the need for manual adjustment of the door opening is reduced, the degree of automation is improved, and the operation process of fixing and adjusting the door opening is simplified. Employees can quickly set the door opening, reducing operational complexity, thereby accelerating the production process and improving overall production efficiency.

[0039] According to one embodiment of the present invention, a second limiting groove is also provided on the sliding column 2. The first limiting groove 211 and the second limiting groove are arranged opposite to each other on both sides of the sliding column 2. When the door moves away from the door frame, the door can drive the first sliding shaft 12 and the second sliding shaft 13 to move relative to the sliding column 2 until the first sliding shaft 12 moves into the first limiting groove 211 and the second sliding shaft 13 moves into the second limiting groove. The first limiting groove 211 can restrict the movement of the first sliding shaft 12 relative to the sliding column 2 located in the first limiting groove 211, and the second limiting groove can restrict the movement of the second sliding shaft 13 relative to the sliding column 2 located in the second limiting groove. Through the double restriction of the first limiting groove 211 and the second limiting groove, a fixed opening is maintained between the door and the door frame, making the structure more stable and reliable.

[0040] In one embodiment, the frame body 11 includes a first clamping plate 111 and a second clamping plate 112. The first clamping plate 111 is connected to the vehicle door by a first fastener. The first clamping plate 111 and the second clamping plate 112 are spaced apart along the axial direction of the first sliding shaft 12. The first clamping plate 111 is provided with a first sliding groove 11111 and a second sliding groove 11112. The second clamping plate 112 is provided with a third sliding groove 1121 and a fourth sliding groove 1122. The first sliding shaft 12 passes through the first sliding groove 11111 and the third sliding groove 1121, and the first sliding groove 11111... The groove wall of the first sliding shaft 12 and the groove wall of the third sliding groove 1121 are both slidably engaged with the first sliding shaft 12. The second sliding shaft 13 passes through the second sliding groove 11112 and the fourth sliding groove 1122, and the groove walls of the second sliding groove 11112 and the fourth sliding groove 1122 are both slidably engaged with the second sliding shaft 13. The first clamping plate 111, the second clamping plate 112, the first sliding shaft 12 and the second sliding shaft 13 form a limiting hole 14 for the sliding column 2 to pass through. Specifically, by sliding the first sliding shaft 12 and the second sliding shaft 13 in the corresponding sliding grooves, the sliding fit of the first sliding shaft 12 and the second sliding shaft 13 can reduce the sliding fit of the first sliding shaft 12 and the second sliding shaft 13. The friction between the second sliding shaft 13 and the first clamping plate 111 and the second clamping plate 112 reduces the wear of the door opening fixing fixture 100, extends its service life, and is easy for employees to understand and use, as well as for maintenance. The sliding column 2 can slide within the limiting hole 14 formed by the first clamping plate 111, the second clamping plate 112, the first sliding shaft 12, and the second sliding shaft 13, which prevents the sliding column 2 from sliding out of the first sliding shaft 12 and the second sliding shaft 13, thus ensuring the stability of the door opening fixing fixture 100. In addition, in this embodiment, the first slide groove 11111 and the second slide groove 11112 can be spaced apart in the front-back direction, and the third slide groove 1121 and the fourth slide groove 1122 can be spaced apart in the front-back direction. The first slide groove 11111, the second slide groove 11112, the third slide groove 1121 and the fourth slide groove 1122 can all extend in the front-back direction, so that the first slide shaft 12 and the second slide shaft 13 can slide and cooperate with the corresponding slide groove under the action of the elastic limiting component 3, thereby abutting against the two sides of the slide column 2 that are arranged opposite to each other in the front-back direction.

[0041] According to one embodiment of the present invention, the first slide groove 11111 and the second slide groove 11112 are spaced apart, and the third slide groove 1121 and the fourth slide groove 1122 are spaced apart. The extension directions of the first slide groove 11111, the second slide groove 11112, the third slide groove 1121 and the fourth slide groove 1122 are all inclined, that is, the extension directions of the first slide groove 11111, the second slide groove 11112, the third slide groove 1121 and the fourth slide groove 1122 may have an angle with the front-back direction, so that the first slide shaft 12 and the second slide shaft 13 can slide and cooperate with the corresponding slide groove under the action of the elastic limiting component 3, thereby abutting against the two sides of the slide column 2 that are arranged opposite to each other in the front-back direction.

[0042] According to another embodiment of the present invention, the first slide groove 11111 and the second slide groove 11112 are arranged along the front-back direction and are connected. The third slide groove 1121 and the fourth slide groove 1122 are arranged at intervals along the front-back direction and are connected. This allows the first slide shaft 12 and the second slide shaft 13 to slide and cooperate with the corresponding slide grooves under the action of the elastic limiting component 3, thereby abutting against the two sides of the slide column 2 that are arranged opposite to each other along the front-back direction.

[0043] In one embodiment, the first sliding shaft 12 includes a first shaft body 121 and a first abutting portion 122, the first abutting portion 122 being sleeved on the outer wall of the first shaft body 121. The second sliding shaft 13 includes a second shaft body 131 and a second abutting portion 132, the second abutting portion 132 being sleeved on the outer wall of the second shaft body 131. The first abutting portion 122 and the second abutting portion 132 are arranged along a first direction. The first shaft body 121 passes through a first sliding groove 11111 and a third sliding groove 1121, and the groove walls of the first sliding groove 11111 and the third sliding groove 1121 are both slidably engaged with the first shaft body 121. The second shaft body 131 passes through a second sliding groove 11112 and a fourth sliding groove 1122, and the first sliding groove 121... The walls of the second sliding groove 11112 and the fourth sliding groove 1122 are both slidably engaged with the second shaft body 131. The first clamping plate 111, the second clamping plate 112, the first abutting part 122, and the second abutting part 132 form a limiting hole 14. The two ends of the first abutting part 122 abut against the first clamping plate 111 and the second clamping plate 112 respectively to restrict the movement of the first sliding shaft 12 relative to the frame body 11. The two ends of the second abutting part 132 abut against the first clamping plate 111 and the second clamping plate 112 respectively to restrict the movement of the second sliding shaft 13 relative to the frame body 11. The first shaft body 121 and the second shaft body 131 are both connected to the elastic limiting component 3 so that the elastic limiting component 3 can drive the first abutting part 122 and the second abutting part 132. The abutment portions 132 approach each other and abut against the two sides of the sliding column 2 respectively. As the door moves away from the door frame, the door can move the first abutment portion 122 and the second abutment portion 132 relative to the sliding column 2 until the first abutment portion 122 moves into the first limiting groove 211. The first limiting groove 211 can restrict the movement of the first abutment portion 122 relative to the sliding column 2 within the first limiting groove 211, thus limiting further movement of the door away from the door frame. Specifically, in this embodiment, the first abutment portion 122 is fixedly connected to the outer wall of the first shaft body 121, and the second abutment portion 132 is fixedly connected to the outer wall of the second shaft body 131. The two ends of the first abutment portion 122 and the second abutment portion 132... Both ends of 2 abut against the first clamping plate 111 and the second clamping plate 112 respectively. By setting the first abutting part 122 and the second abutting part 132, stable positioning points are provided for the first shaft body 121 and the second shaft body 131, which restricts the axial movement of the first shaft body 121 and the second shaft body 131. This effectively controls the movement of the first shaft body 121 and the second shaft body 131, reduces the maintenance and adjustment work caused by the displacement of the first sliding shaft 12 and the second sliding shaft 13, lowers maintenance costs, improves the safety, stability and durability of operation, reduces production interruptions caused by adjusting the position of the first sliding shaft 12 and the second sliding shaft 13, and improves the continuity and production efficiency of the production line.

[0044] According to one embodiment of the present invention, a first abutting portion 122 is sleeved on the outer wall of a first shaft body 121, and the first abutting portion 122 is rotatably connected to the first shaft body 121. A second abutting portion 132 is sleeved on the outer wall of a second shaft body 131, and the second abutting portion 132 is rotatably connected to the second shaft body 131. The two ends of the first abutting portion 122 abut against the first clamping plate 111 and the second clamping plate 112 respectively to restrict the movement of the first sliding shaft 12 relative to the frame body 11. The two ends of the second abutting portion 132 abut against the first clamping plate 111 and the second clamping plate 112 respectively. 1. The second clamping plate 112 abuts against each other to restrict the movement of the second sliding shaft 13 relative to the frame body 11; by setting the first abutting part 122 to be rotatably connected to the first shaft body 121 and the second abutting part 132 to be rotatably connected to the second shaft body 131, the first abutting part 122 and the second abutting part 132 can respectively roll and cooperate with the two sides of the sliding column 2 that are arranged opposite each other in the front and rear direction, thereby reducing the friction force when the first sliding shaft 12 and the second sliding shaft 13 move relative to the sliding column 2, making the operation of opening or closing the door relative to the door frame smoother and more fluid.

[0045] In one embodiment, the first clamping plate 111 includes a plate body 1111 and a mounting plate 1112. The mounting plate 1112 is connected to the vehicle door via a first fastener. Both the plate body 1111 and the second clamping plate 112 are connected to the mounting plate 1112, and the plate body 1111 and the second clamping plate 112 are spaced apart along the axial direction of the first sliding shaft 12. The plate body 1111 is provided with a first sliding groove 11111 and a second sliding groove 11112. The plate body 1111, the second clamping plate 112, the first abutment portion 122, and the second abutment portion 132 form a limiting hole 14. The mounting plate 1112 is provided with a threaded hole 11121. The first fastener includes a first bolt (not shown in the figure), which passes through the first mounting hole on the vehicle door and is threaded into the threaded hole 11121. The mounting plate 1112 has a through hole 11122 for the sliding column 2 to pass through. Specifically, the first bolt passes through the first mounting hole on the door and is threaded into the threaded hole 11121, thereby achieving the fixed installation of the mounting bracket 1 and the door. This threaded connection increases the strength between the door opening fixing clamp 100 and the door, so that the door opening fixing clamp 100 can be stably and reliably fixed to the door. It is also easy to install and disassemble. Moreover, the threaded connection can meet the needs of different vehicle models and working environments, and can work stably under various conditions, improving the versatility of the door opening fixing clamp 100.

[0046] In one embodiment, the first slide groove 11111 has a first opening 11111a at one end away from the second slide groove 11112; and / or, the second slide groove 11112 has a second opening 11112a at one end away from the first slide groove 11111; and / or, the third slide groove 1121 has a third opening 1121a at one end away from the fourth slide groove 1122; and / or, the fourth slide groove 1122 has a fourth opening 1122a at one end away from the third slide groove 1121; specifically, the first opening 11111 on the first slide groove 11111... a. The second opening 11112a on the second slide rail 11112, the third opening 1121a on the third slide rail 1121, and the fourth opening 1122a on the fourth slide rail 1122 make the installation and adjustment of the first slide shaft 12 and the second slide shaft 13 more convenient. Employees can more easily operate the first slide shaft 12 and the second slide shaft 13 at the openings to perform installation or maintenance work. In addition, the design of the openings makes it easier to inspect and clean the inside of each slide rail, which helps to keep the inside of each slide rail clean and reduce failures caused by contamination.

[0047] In one embodiment, the elastic limiting component 3 includes a first elastic limiting member 31 and a second elastic limiting member 32. The first elastic limiting member 31 and the second elastic limiting member 32 are spaced apart along the axial direction of the first sliding shaft 12, and are respectively located on opposite sides of the sliding column 2. The first sliding shaft 12 and the second sliding shaft 13 are both connected to the first elastic limiting member 31, and both the first sliding shaft 12 and the second sliding shaft 13 are connected to the second elastic limiting member 32. Specifically, the first elastic limiting member 31 and the second elastic limiting member 32 are respectively located on opposite sides of the sliding column 2 in the left-right direction. This symmetrical layout enhances the structural stability of the entire door opening fixing clamp 100. The first and second elastic limiting members 31 and 32 can drive the first sliding shaft 12 and the second sliding shaft 13 to move closer to each other and abut against the two sides of the sliding column 2 that are arranged opposite each other in the front-rear direction. This ensures that the first sliding shaft 12 accurately falls into the first limiting groove 211 when it moves relative to the sliding column 2, thereby improving the limiting effect and keeping the door at a fixed opening. This reduces the problem of uneven spraying caused by changes in opening. In addition, both the first elastic limiting member 31 and the second elastic limiting member 32 are elastic, so that the first sliding shaft 12 and the second sliding shaft 13 can adapt to the size of the sliding shaft. This can compensate for the gap caused by manufacturing errors or wear, reduce abnormal wear between components, extend the service life of the door opening fixing fixture 100, and improve operating efficiency and user experience.

[0048] In one embodiment, the first sliding shaft 12 is provided with a first groove 1211 and a second groove 1212, and the second sliding shaft 13 is provided with a third groove 1311 and a fourth groove 1312. The two ends of the first elastic limiting member 31 are respectively located within the first groove 1211 and the third groove 1311, and the two ends of the second elastic limiting member 32 are respectively located within the second groove 1212 and the fourth groove 1312. Specifically, the first groove 1211 and the second groove 1212 provide precise positioning points for the first elastic limiting member 31, and the third groove 1311 and the fourth groove 1312 serve as positioning points for the second elastic limiting member 32. Precise positioning points are provided, making the elastic limiting component 3 more securely fixed, enhancing the stability, durability, and safety of the entire door opening fixing clamp 100. This prevents accidental movement of the first sliding shaft 12 and the second sliding shaft 13 or the first elastic limiting component 31 and the second elastic limiting component 32 during operation, ensuring that the first elastic limiting component 31 and the second elastic limiting component 32 function in the correct position, improving the accuracy of door opening control. Furthermore, the four grooves provide clear installation positions for the elastic limiting component 3, simplifying the installation process and facilitating future maintenance and replacement of the elastic limiting component 3.

[0049] In one embodiment, the first elastic limiting member 31 includes a first spring; and / or, the second elastic limiting member 32 includes a second spring. Specifically, the use of the first spring and the second spring can provide appropriate elastic force to the first sliding shaft 12 and the second sliding shaft 13, so that the first sliding shaft 12 and the second sliding shaft 13 can approach each other and abut against the two sides of the sliding column 2 that are arranged opposite to each other in the front-rear direction, thereby improving the limiting effect and ensuring that the door can be kept at a fixed opening, thereby reducing the problem of uneven spraying caused by changes in opening and improving the spraying effect. Moreover, the first spring and the second spring can provide appropriate elastic force according to the thickness of the sliding column 2 and the quality requirements of the door, so that the door opening fixing clamp 100 can adapt to various models, and can also compensate for gaps caused by manufacturing errors or wear, reduce abnormal wear between parts, extend the service life of the door opening fixing clamp 100, and improve operating efficiency and user experience. In this embodiment, the first elastic limiting member 31 may be a first spring or other elastic component, and the second elastic limiting member 32 may be a second spring or other elastic component. This embodiment does not limit the specific selection of the first elastic limiting member 31 and the second elastic limiting member 32.

[0050] In one embodiment, the sliding column 2 includes a column body 21 and a connector 22. The connector 22 is rotatably mounted on the column body 21 and has a through hole 221. The second fastener includes a second bolt (not shown) and a nut (not shown). The second bolt passes through the through hole 221 and a second mounting hole on the door frame and is threadedly connected to the nut. The elastic limiting component 3 can drive the first sliding shaft 12 and the second sliding shaft 13 to move closer to each other and abut against the two sides of the column body 21 that are arranged opposite each other in the front-rear direction. The column body 21 has a first limiting groove 211. Specifically, the connector 22 is rotatably mounted on the column body 21, which can prevent the sliding column 2 from deforming or being damaged when the mounting bracket 1 moves away from the door frame as the door moves. The sliding column 2 is threadedly connected to the second mounting hole on the door frame through the through hole 221 and the nut, thereby achieving a fixed connection between the sliding column 2 and the door frame. This threaded connection increases the strength between the door opening fixing clamp 100 and the door frame, allowing the door opening fixing clamp 100 to be stably and reliably fixed to the door frame. It also facilitates installation and disassembly. Furthermore, the threaded connection method can meet the needs of different vehicle models and working environments, and can work stably under various conditions, improving the versatility of the door opening fixing clamp 100. In this embodiment, the connecting member 22 is rotatably connected to one end of the column body 21. The connecting member 22 can also prevent the first sliding shaft 12 from accidentally dislodging from the sliding column 2 during operation, thereby improving the safety of using the door opening fixing clamp 100. In this embodiment, the column body 21 and the connecting member 22 can be rotatably connected by a pin, or the column body 21 and the connecting member 22 can be hinged to achieve a rotatable connection. This embodiment does not limit the specific connection method of the column body 21 and the connecting member 22.

[0051] In one embodiment, the first limiting groove 211 includes a first locking groove 2111 and a second locking groove 2112, which are spaced apart along the axial direction of the sliding column 2. Specifically, in this embodiment, the car door has a first opening degree and a second opening degree, and the car door painting has a first painting requirement and a second painting requirement. When the car door is at the first painting requirement, the first painting requirement of the car door can be met; when the car door is at the second opening degree, the second painting requirement of the car door can be met. When the first sliding shaft 12 moves relative to the sliding column 2 into the first locking groove 2111, the first sliding shaft 12 is restricted by the first locking groove 2111 and cannot continue to move relative to the sliding column 2, so that the first opening degree is formed between the car door and the door frame to meet the first painting requirement of the car door. When the second sliding shaft 13 moves relative to the sliding column 2 into the second slot 2112, the second sliding shaft 13 is restricted by the second slot 2112 and cannot continue to move relative to the sliding column 2, so that a second opening is formed between the door and the door frame to meet the second painting requirements of the door. By setting the first slot 2111 and the second slot 2112, the door opening is fixed, which makes it convenient for the robot to perform painting operations with a fixed program and ensures the stability of quality, without the need for employees to manually operate the door. This reduces the need for manual adjustment of the door opening, improves the degree of automation, simplifies the operation process of fixing and adjusting the door opening, and allows employees to quickly set the door opening, reducing the complexity of operation, thereby speeding up the production process and improving the overall production efficiency.

[0052] In this embodiment, the number of first slots 2111 is at least one, and the number of second slots 2112 is at least one. Multiple first slots 2111 and multiple second slots 2112 can be set on the sliding column 2 according to the actual spraying requirements. Each first slot 2111 corresponds to a different first opening degree, and each second slot 2112 corresponds to a different second opening degree, thereby meeting different spraying requirements. In this embodiment, the specific number of first slots 2111 and second slots 2112 is not limited.

[0053] In this embodiment, a first limiting protrusion is provided on the slide column 2, which can abut against the first slide shaft 12 to prevent the first slide shaft 12 from dislodging from the slide column 2; and / or, a second limiting protrusion is provided on the slide column 2, which can abut against the second slide shaft 13 to prevent the second slide shaft 13 from dislodging from the slide column 2; specifically, in this embodiment, a first limiting protrusion is provided on the slide column 2, which can abut against the first slide shaft 12 to prevent the first slide shaft 12 from dislodging from the slide column 2. By providing the first limiting protrusion, the first slide shaft 12 can be prevented from accidentally dislodging from the slide column 2 during operation, thereby improving the safety of the door opening fixing clamp 100. Moreover, by providing the first limiting protrusion on the slide column 2 to achieve limiting, the overall design of the door opening fixing clamp 100 can be simplified, the number of required components can be reduced, and the manufacturing complexity can be reduced.

[0054] According to one embodiment of the present invention, a second limiting protrusion is provided on the sliding column 2. The second limiting protrusion can abut against the second sliding shaft 13 to restrict the second sliding shaft 13 from dislodging from the sliding column 2. By providing the second limiting protrusion, the second sliding shaft 13 can be prevented from accidentally dislodging from the sliding column 2 during operation, thereby improving the safety of the door opening fixing clamp 100. Furthermore, by providing the second limiting protrusion on the sliding column 2 to achieve the limiting, the overall design of the door opening fixing clamp 100 can be simplified, the number of required components can be reduced, and the manufacturing complexity can be reduced.

[0055] According to another embodiment of the present invention, the slide column 2 is provided with a first limiting protrusion and a second limiting protrusion. The first limiting protrusion can abut against the first slide shaft 12 to restrict the first slide shaft 12 from dislodging from the slide column 2, and the second limiting protrusion can abut against the second slide shaft 13 to restrict the second slide shaft 13 from dislodging from the slide column 2. By providing the first limiting protrusion and the second limiting protrusion, the first slide shaft 12 and the second slide shaft 13 can be prevented from accidentally dislodging from the slide column 2 during operation, thereby improving the safety of the door opening fixing fixture 100. Moreover, the first limiting protrusion and the second limiting protrusion can play a double limiting role. Even if the first limiting protrusion fails, the second limiting protrusion can still prevent the second slide shaft 13 from dislodging, thereby increasing the reliability of the door opening fixing fixture 100, reducing downtime caused by slide shaft dislodging, and improving the continuity and production efficiency of the production line.
