[0002] In the automobile manufacturing industry, it is often necessary to accurately weld long strip-shaped parts with a bending structure onto a main body part, such as a part of a vehicle body, and the long strip-shaped parts, such as curved edge strips of a vehicle door frame. These parts not only have a complex shape, but also require accurate welding positions and high joint strength to ensure the structural integrity and safety of the entire vehicle.

[0003] However, the length of the long strip-shaped part is relatively long, and the line to be welded is a curve. The traditional pressing device with a longer pressing part is not suitable for the curved welding route. The traditional pressing device with a shorter pressing part can only press the front end or the middle section of the part, and lacks effective clamping measures for the rear end. This leads to the possibility of the rear end of the part shaking or moving during the welding process, thereby affecting the stability of the entire part and the quality of the welded joint.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, a clamping device includes a clamping part 2 and a clamping part 1. The clamping part 2 is disposed on one side of the clamping part 1. The clamping part 2 includes a clamping block 21 and a first power cylinder 22. The first power cylinder 22 drives the clamping block 21 to move along a first direction. The clamping block 21 has a clamping surface with a recess to form a clamping groove 211. The clamping part 1 includes a clamping block 11 and a second power cylinder 12. The first power cylinder 22 drives the clamping block 11 to move along a second direction. The second direction is perpendicular to the first direction. The clamping block 11 has a recess to form a clamping groove 111. The clamping groove 211 is inclined to the clamping groove 111.

[0024] The clamping part 2 and the holding part 1 are independently arranged. The clamping part 2 includes a clamping block 21 and a linear first power cylinder 22. The first power cylinder 22 is fixed to the base of the device by bolts, and its piston rod is connected to the rear end of the clamping block 21. When the first power cylinder 22 receives a start signal, the piston rod extends, pushing the clamping block 21 to move in a first direction. It is worth noting that the first direction is... Figure 1 The clamping block 21 moves in the up and down directions, i.e., towards or away from the workpiece, until its front end contacts or clamps the target workpiece. The front end face of the clamping block 21 is designed as a clamping surface, with a V-shaped clamping groove 211 machined thereon to increase friction with the contact surface of the elongated part and improve the clamping effect. The inclination angle of the clamping groove 211 is optimized according to the shape and material of the workpiece to ensure optimal clamping stability.

[0025] The clamping part 1 and the pressing part 2 are arranged adjacent to each other. The clamping part 1 includes a clamping block 11 and a second power cylinder 12. The second power cylinder 12 drives the clamping block 11 to move along a second direction. Figure 1 Move it left and right in the middle until the clamping groove 111 on the clamping block 11 tightly surrounds the other part of the long strip-shaped part.

[0026] In use, first, the rear end of the long strip-shaped part is installed in the clamping groove 111 of the clamping block 11, and is moved to a set position along the second direction, then the pressing part 2 is close to the long strip-shaped part along the first direction, the long strip-shaped part is placed in the pressing groove 211 and is pressed against the main body part, the pressing part 2 continues to move along the first direction until the long strip-shaped part is tightly attached to the main body part, and then the welding device welds between the long strip-shaped part and the main body part. The clamping part 1 and the pressing part 2 jointly act to firmly fix the workpiece at a predetermined position, providing stable support for subsequent processing. After the welding of the pressing part 2 is completed and cooled, the clamping part 1 releases the clamping of the long strip-shaped part, the pressing part 2 moves away from the main body part along the first direction, and then the main body part rotates in the same direction as the welding route, and then the pressing part 2 again presses the long strip-shaped part and the main body part along the first direction, and performs the next stage of welding. At this time, the structure of the welded part is stable, and the stage of welding forms stable support.

[0027] Further, the pressing part 2 includes an abutting part 23, which is arranged on the side of the pressing block 21 close to the clamping block 11. As shown in Figure 1 and Figure 3 , the abutting part 23 can form support and limit for the bottom of the clamping block 11.

[0028] The abutting part 23 is a protruding structure attached to the side of the pressing block 21 close to the clamping block 11. In the schematic view of Figure 1 and Figure 3 , the abutting part 23 is a protruding structure towards the clamping block 11, and the bottom surface is lower than the pressing surface. The abutting part 23 supports the clamping block 11 in case of excessive force and shaking, and limits the limit distance of the pressing part 2 moving along the first direction. When the abutting part 23 touches the clamping block 11 or the tail of the long strip-shaped part clamped on the clamping block 11, the movement of the pressing part 2 along the first direction is stopped, forming a limit.

[0029] Further, the first power cylinder 22 includes a first air cylinder 221, two guide mechanisms 222, a mounting frame, the two guide mechanisms 222 are respectively arranged on both sides of the first air cylinder 221, the first air cylinder 221 and the two guide mechanisms 222 are arranged along the first direction, the first air cylinder 221 and the two guide mechanisms 222 are mounted on the mounting frame, and the pressing block 21 is mounted on the mounting frame.

[0030] The first cylinder 221 serves as the main power source for driving the movement of the pressing block 21. The first cylinder 221 is arranged along the first direction, and its piston rod is directly or indirectly connected to the pressing block 21 for pushing the pressing block 21 to move along the first direction. To improve the straightness and stability of the movement of the pressing block 21, a guide mechanism 222 is arranged on both sides of the first cylinder 221. The guide mechanism 222 is a linear guide mechanism 222 composed of a guide column 2221 and a sleeve 2222. The guide mechanism 222 is arranged along the first direction and installed on the mounting frame, providing precise guidance and support for the movement of the pressing block 21. The presence of the guide mechanism 222 effectively prevents the deviation or shaking of the pressing block 21 during movement, improving the precision and reliability of the pressing device. The mounting frame is used to install and fix the first cylinder 221, the guide mechanism 222, and the pressing block 21, etc.

[0031] By introducing the guide mechanism 222, precise guidance and support are provided for the movement of the pressing block 21, effectively preventing deviation or shaking of the pressing block 21 during movement, improving the movement precision and stability of the pressing device.

[0032] The mounting frame, as an important support structure of the pressing device, ensures that each component can work stably and reliably. At the same time, the arrangement of the guide mechanism 222 and the first cylinder 221 further enhances the overall structural stability of the pressing device.

[0033] Further, as shown in Figure 3 the mounting frame includes a first mounting block 241 and a second mounting block 242. The first mounting block 241 is connected to the cylinder body of the first cylinder 221, and the second mounting block 242 is connected to the piston rod of the first cylinder 221. The pressing block 21 is installed on the second mounting block 242.

[0034] Furthermore, each guide mechanism 222 includes a guide column 2221 and a sleeve 2222. The sleeve 2222 is sleeved outside the guide column 2221, and the sleeve 2222 is installed in the first mounting block 241. The guide column 2221 is connected to the second mounting block 242.

[0035] As shown in Figure 4As shown, the clamping part 1 also includes a locking part 13 connected with the clamping block 11, and a locking screw 131 is arranged on the locking part 13, which is opposite to the clamping groove 111. The locking part 13 is arranged to further enhance the clamping force of the clamping part 1 on the workpiece, ensuring that the workpiece does not move or loosen accidentally during machining or assembly, thereby improving the accuracy and reliability of the operation. The locking part 13 is located above or below the clamping groove 111 and is detachably fixed with the clamping block 11 through bolt connection or other appropriate connection means. The locking part 13 is provided with a locking screw 131 arranged in a direction perpendicular to the clamping groove 111, and the front end of the locking screw 131 is opposite to the opening of the clamping groove 111.

[0036] Preferably, the head of the locking screw 131 can be a shape convenient for manual or tool operation, such as hexagonal, slot or cross slot, etc. When the clamping block 11 clamps the workpiece, the operator can manually or use a tool to rotate the locking screw 131, so that the front end of the locking screw 131 gradually penetrates into the clamping groove 111 and presses on the workpiece. The locking screw 131 further increases the clamping force of the clamping part 1 on the workpiece, preventing the workpiece from loosening or moving during machining or assembly due to vibration, impact and other factors.

[0037] The addition of the locking part 13 enables the clamping part 1 to apply additional clamping force to the workpiece through the locking screw 131, further enhancing the stability of the workpiece during machining or assembly, and avoiding processing errors or assembly failures caused by workpiece loosening. The precise adjustment and tightening of the locking screw 131 enable the workpiece to be stably fixed in the predetermined position, thereby improving the accuracy and reliability of the machining or assembly operation. The tightening of the locking screw 131 effectively prevents safety accidents caused by accidental movement of the workpiece during machining or assembly, improving the safety of the operation.

[0038] Referring to Figure 2 , the pressing groove 211 is arc-shaped. The arc-shaped pressing groove 211 can better adapt to workpieces of different shapes and sizes, especially those with curved or irregular parts. Compared with traditional straight or V-shaped pressing grooves 211, the arc-shaped pressing groove 211 can provide a wider contact area and more uniform pressure distribution, thereby more effectively fixing the workpiece and preventing it from moving or deforming during machining or assembly. The arc-shaped pressing groove 211 design can increase the friction force of the contact surface with the workpiece, because the arc-shaped surface can form more micro contact points when in contact, which will generate greater resistance during pressing, thereby enhancing the pressing effect. This design is particularly suitable for machining or assembly operations that require high precision and stability.

[0039] Since the arc-shaped pressing groove 211 can better adapt to the shape of the workpiece, the operator can adjust the position and angle of the pressing device more quickly to achieve precise pressing of the workpiece. This reduces the adjustment time and operation difficulty, and improves the overall work efficiency.

[0040] Further, referring to Figure 3 As shown, the pressing block 21 includes a rear end portion 212 and a front end portion 213, the rear end portion 212 is arranged along the first direction, and the front end portion 213 is obliquely connected with the rear end portion 212, the pressing surface is arranged on the front end portion 213, and the rear end portion 212 is connected to the second mounting block 242.

[0041] The rear end portion 212 of the pressing block 21 is arranged along the first direction, and is used to connect with the second mounting block 242. The rear end portion 212 can be fixed on the second mounting block 242 by bolt connection, welding or other appropriate connection methods, to ensure the stability and reliability of the pressing block 21 during movement.

[0042] The front end portion 213 of the pressing block 21 is obliquely connected with the rear end portion 212, forming an inclined surface or inclined surface. This inclined design makes the pressing surface better adapt to the curvature or inclination angle of the workpiece surface, thereby providing more uniform and stable pressing force during pressing. The inclination angle of the front end portion 213 can be set according to the shape and size of the workpiece.

[0043] The pressing surface is arranged on the front end portion 213, which is the part of the pressing block 21 directly contacting the workpiece. The pressing surface can be designed as a plane, a curved surface or other shapes to adapt to the shape and size of different workpieces.

[0044] The embodiments of the specific implementation are the preferred embodiments of the utility model, which do not limit the protection scope of the utility model, so that: any equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
