Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0038] An embodiment of the present application provides a lower body clamp 100. It should be noted that the lower body clamp 100 in the present application may refer to a welding clamp, an assembly clamp, a detection clamp, etc. The lower body clamp 100 is generally provided with a base, a support structure and a clamping mechanism, etc. The support structure is used to support the lower body, and the clamping mechanism is used to clamp the lower body.

[0039] It should be noted that, in this embodiment, the clamping method of the clamping mechanism is not limited.

[0040] The lower vehicle body clamp 100 provided in the embodiment of the present application is used to measure the connection quality of the lower vehicle body after clamping the lower vehicle body.

[0041] For example, for some lower body fixtures, for the bottom of the lower body and some central positions of the body, the lower body needs to be rotated to different angles or even flipped 180° before the inspectors can operate the inspection tools (such as ultrasonic flaw detectors, FDS torque meters, SPR rivet head height meters, etc.) to inspect the connection points.

[0042] On this basis, refer to Figure 1 An embodiment of the present application provides a lower vehicle body clamp 100 for clamping the lower vehicle body and includes a mounting base 1, a rotating bracket 2 and a clamping mechanism 3.

[0043] In order to better illustrate the lower body clamp 100 provided in the embodiment of the present application, the rotating bracket 2 is rotatably arranged on the mounting base 1, and the clamping mechanism 3 is movably arranged in the thickness direction of the rotating bracket 2 (such as Figure 1 One side of the first direction shown is used to adapt to clamping lower bodies of different models.

[0044] It is understood that the clamping mechanism 3 can clamp the lower vehicle body to the rotating bracket 2. The rotating bracket 2 can rotate the lower vehicle body to any angle while maintaining a fixed clamp, facilitating non-destructive testing of welds and rivets on certain locations of the lower vehicle body, as well as welding and assembly operations. The clamping mechanism 3 can change its clamping position through movement or rotation, thereby adapting to different models of lower vehicle bodies. The clamping mechanism 3 can clamp different models of lower vehicle bodies, and the lower vehicle body clamp 100 has high versatility, which can reduce the manufacturing cost of the lower vehicle body.

[0045] According to the lower vehicle body clamp 100 of the embodiment of the present invention, the clamping mechanism 3 can clamp the lower vehicle body on the rotating bracket 2, the rotating bracket 2 can rotate the lower vehicle body to any angle and keep it fixed and clamped, and the clamping mechanism 3 can adaptably clamp lower vehicle bodies of different models through movements such as movement or rotation. The lower vehicle body clamp 100 has good versatility and can save the manufacturing cost of the lower vehicle body.

[0046] In addition, in the embodiment of the present application, the clamping mechanism 3 is not limited, as long as it can clamp the lower vehicle body.

[0047] In some embodiments of the present application, reference is made to Figure 1 and Figure 4The lower body clamp 100 also includes a first driving device 4, which is used to drive the clamping mechanism 3 to move along the thickness direction of the rotating bracket 2. After the lower body is placed on the rotating bracket 2, the first driving device 4 can adjust the position of the clamping mechanism 3 in the thickness direction of the rotating bracket 2 according to the position of the lower body along the thickness direction of the rotating bracket 2 to meet the clamping requirements of different lower bodies.

[0048] For example, in an embodiment of the present application, the first driving device 4 is a first cylinder, and the lower body clamp 100 also includes a switching panel 8, which stores model information of different lower bodies and the corresponding clamping positions of the clamping mechanism 3 and can transmit signals to the solenoid valve. The solenoid valve controls the first cylinder according to the signal transmitted by the switching panel 8, and then controls the clamping mechanism 3 to move along the thickness direction of the rotating bracket 2 to meet the clamping requirements of different lower bodies.

[0049] In this embodiment, the clamping mechanism 3 includes a support block 31, a clamping cylinder 34, a pressure arm 32 and a pressure head 33. The support block 31 is fixedly connected to the rotating bracket 2. The first drive device 4 drives the pressure arm 32 to move along the thickness direction of the rotating bracket 2. The clamping cylinder 34 drives the pressure head 33 to rotate, so that the pressure head 33 can switch between clamping the lower car body and releasing the lower car body to meet the clamping requirements of different lower car bodies.

[0050] On this basis, refer to Figure 2 In some embodiments of the present application, the lower body clamp 100 also includes a positioning mechanism 5, which is arranged on the side of the rotating bracket 2 in the thickness direction where the clamping mechanism 3 is provided, and is used to limit the lower body so that when the lower body is installed on the lower body clamp 100, it can enter the correct position more smoothly under the limitation of the positioning mechanism 5, which is convenient for the operator to perform subsequent operation steps.

[0051] Further, refer to Figure 1 and Figure 2 The positioning mechanism 5 includes a first positioning column 51 and a second positioning column 52, which rotates the width direction of the bracket 2 (such as Figure 1 A first positioning column 51 is provided at at least one end of the rotating bracket 2 (in the second direction shown), and the first positioning column 51 and the lower vehicle body are arranged in sequence along the width direction of the rotating bracket 2. The first positioning column 51 is used to limit the lower vehicle body in the width direction of the rotating bracket 2, so that the position of the lower vehicle body in the width direction of the rotating bracket 2 is more reliable, which is convenient for the operator to perform subsequent clamping operations.

[0052] The length direction of the rotating bracket 2 (such as Figure 1A second positioning column 52 is provided at at least one end of the rotating bracket 2 (the third direction shown in the figure). Along the length direction of the rotating bracket 2, the second positioning column 52 and the lower vehicle body are arranged in sequence. The second positioning column 52 is used to limit the lower vehicle body in the length direction of the rotating bracket 2, so that the position of the lower vehicle body in the length direction of the rotating bracket 2 is more reliable, which is convenient for the operator to perform subsequent clamping operations.

[0053] Furthermore, refer to Figure 1 and Figure 3 The positioning mechanism 5 further includes a positioning pin 53, which is provided with a corresponding positioning hole on the lower body. The positioning pin 53 is movable along the thickness direction of the rotating bracket 2. It is understood that the positions of the positioning holes on different lower bodies may be different along the thickness direction of the rotating bracket 2. By adjusting the positioning pin 53 along the thickness direction of the rotating bracket 2, the positioning pin 53 can be smoothly inserted into different lower bodies, making the positioning effect of the positioning pin 53 more reliable.

[0054] Furthermore, refer to Figure 1 and Figure 5 The positioning mechanism 5 also includes a second driving device 54, which drives the positioning pin 53 to move along the thickness direction of the rotating bracket 2. After the lower body is placed on the rotating bracket 2, the second driving device 54 can adjust the position of the positioning pin 53 in the thickness direction of the rotating bracket 2 according to the position of the positioning hole on the lower body along the thickness direction of the rotating bracket 2 to meet the positioning requirements of different lower bodies.

[0055] For example, in an embodiment of the present application, the second driving device 54 is a second cylinder, and the solenoid valve controls the second cylinder according to the signal transmitted by the switching panel 8, thereby controlling the positioning pin 53 to move along the thickness direction of the rotating bracket 2 to meet the clamping requirements of different lower bodies.

[0056] In some embodiments of the present application, reference is made to Figure 1 and Figure 6 The mounting base 1 includes a base 11 and a rotating arm 12. The bases 11 are spaced apart and can limit the position of the rotating bracket 2 at two locations, making the position of the rotating bracket 2 more reliable. There are two rotating arms 12 corresponding to the two bases 11. The rotating arms 12 are rotatably connected to the bases 11. The two ends of the rotating bracket 2 in the longitudinal direction are respectively fixedly connected to the two rotating arms 12. The rotating arms 12 rotate synchronously with the rotating bracket 2. The rotating bracket 2 can be rotated by rotating the rotating arms 12 to rotate, thereby realizing the rotation of the lower body.

[0057] On this basis, refer to Figure 1In some embodiments of the present application, the two ends of the rotating bracket 2 in the length direction are respectively connected to one end of the two rotating arms 12 in the length direction, and the mounting base 1 also includes a counterweight 13. A counterweight 13 is provided at the end of each rotating arm 12 in the length direction away from the rotating bracket 2. Along the length direction of the rotating arm 12, the position where the rotating arm 12 is rotatably connected to the base 11 is set between the counterweight 13 and the rotating bracket 2. When the rotating arm 12 rotates, the rotating bracket 2 rotates synchronously. The counterweight 13 can prevent the lower body clamp 100 from becoming unbalanced and tipping over when the rotating bracket 2 rotates, thereby preventing damage to the lower body and the lower body clamp 100, and at the same time preventing the lower body clamp 100 from injuring or damaging the operator and surrounding objects, thereby increasing the operational safety of the lower body clamp 100.

[0058] Further, refer to Figure 1 and Figure 2 The lower vehicle body fixture 100 further includes a third driving device 6 , which is disposed on one of the bases 11 and is used to drive the rotating arm 12 to rotate, thereby realizing the rotation of the rotating bracket 2 and the lower vehicle body disposed on the rotating bracket 2 .

[0059] On this basis, with reference to the figures, in some embodiments of the present application, the third driving device 6 includes a reducer 61 and a rotating wheel 62. The reducer 61 is provided on the base 11. The output shaft of the reducer 61 rotates synchronously with the rotating arm 12, which can achieve low-speed, uniform rotation of the rotating arm 12, thereby achieving low-speed, uniform rotation of the rotating bracket 2 and the lower vehicle body provided on the rotating bracket 2. It can also reduce the inertia of the rotating arm 12, the rotating bracket 2, and the lower vehicle body provided on the rotating bracket 2, reduce energy loss, and reduce the maintenance cost of the lower vehicle body clamp 100. The rotating wheel 62 is provided at the input end of the reducer 61 and is used to drive the output shaft of the reducer 61 to rotate. The operator can manually rotate the rotating wheel 62 so that the rotating arm 12, the rotating bracket 2, and the lower vehicle body provided on the rotating bracket 2 can rotate at the speed required by the operator, and the operation process is relatively simple and convenient.

[0060] In some embodiments of the present application, reference is made to Figure 1 The lower body fixture 100 also includes a locking mechanism 7, which is used to lock the rotating bracket 2. When the rotating bracket 2 drives the lower body to rotate to the desired position, the rotating bracket 2 can be locked, so that the lower body stays in the desired position, which is convenient for operators to perform measurement, welding and other operations.

[0061] For example, in the embodiments of this application, refer to Figure 2 and Figure 3The locking mechanism 7 includes an unlocking rod 71 and a locking pin 72. The unlocking rod 71 is used to stop the rotating wheel 62 to prevent the rotating wheel 62 from continuing to rotate. The locking pin 72 is used to insert into the reducer 61 to prevent the transmission device in the reducer 61 from working. It can double lock to prevent the rotating arm 12, the rotating bracket 2 and the lower vehicle body provided on the rotating bracket 2 from rotating, so that the locking effect of the locking mechanism 7 is relatively simple and reliable.

The above are only preferred embodiments of this application and do not limit the scope of the patent of this application.
