[0002] CDC shock absorber is an advanced automobile suspension system that can adjust the damping force in real time according to road conditions and driving style. During the assembly process of the shock absorber, the buffer and the shock absorber piston rod need to be welded and fixed. During welding, the piston rod is passed through the through hole in the middle of the buffer, and laser spot welding is performed at the gap between the buffer and the piston rod using welding equipment.

Most of the existing testing methods are manual testing. During the testing, the piston rod is placed in a fixture, and the movable plate on the fixture is moved to squeeze the buffer. The welding firmness of the buffer is judged by observing the distance the movable plate moves. This method relies too much on manual operation of the fixture, resulting in low efficiency of welding detection operations. In view of this, the utility model is proposed. Utility Model Content

[0022] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0023] See also Figure 1-Figure 3 , Figure 1 It is a three-dimensional structural schematic diagram of a welding detection device provided by an embodiment of the utility model; Figure 2 It is a three-dimensional structural schematic diagram of a driving component in a welding detection device provided by an embodiment of the utility model; Figure 3 It is a schematic diagram of the exploded structure of the detection component and the clamping component in the welding detection device provided by one embodiment of the utility model. The utility model is used for the welding detection device of the CDC shock absorber, comprising a frame 7, a clamping component, a driving component and a detection component, the clamping component comprising a support base 10 and a support table, the support base 10 is fixed on the frame 7, the support table is fixed on the support base 10, the support base 10 is provided with a first through hole for the shock absorber piston rod 27 to pass through, the support table is provided with a second through hole for supporting the buffer 23, the detection component comprises a lower pressure head 21, the driving component is arranged above the support table and connected to the lower pressure head 21 to drive the lower pressure head 21 to rise and fall.

[0024] By fixing the support base 10 on the frame 7 and fixing the support platform on the support base 10, the support and fixing effect of the shock absorber piston rod 27 can be achieved under the action of the support platform. By opening a first through hole on the support base 10 and a second through hole on the support platform, the shock absorber piston rod 27 can pass through the second through hole and reach the first through hole, and the position of the shock absorber piston rod 27 can be fixed under the supporting effect of the second through hole on the buffer 23. By fixing the lower pressure head 21 on the driving assembly and arranging the driving assembly above the support platform, the position of the lower pressure head 21 can be adjusted under the driving effect of the driving assembly on the lower pressure head 21. When the driving assembly drives the lower pressure head 21 to descend, the lower pressure head 21 can be abutted against the top of the shock absorber piston rod 27 and press the shock absorber piston rod 27 downward.

[0025] Since the buffer 23 is supported on the second through hole, there are two situations when the driving assembly drives the lower pressure head 21 to press the shock absorber piston rod 27. The first situation is that the position of the shock absorber piston rod 27 remains unchanged, and the second situation is that the position of the shock absorber piston rod 27 changes. Correspondingly, when the position of the shock absorber piston rod 27 remains unchanged, it means that the welding firmness of the buffer 23 and the shock absorber piston rod 27 meets the production requirements. Conversely, when the position of the shock absorber piston rod 27 changes, it means that the welding firmness of the buffer 23 and the shock absorber piston rod 27 does not meet the production requirements.

[0026] In the above embodiment, the downward pressure intensity can be preset for the driving component so that when the driving component drives the pressing head 21 to press down, the shock absorber piston rod 27 is pressed according to the preset downward pressure intensity. Therefore, by observing whether the position of the shock absorber piston rod 27 changes, it can be judged whether the welding firmness of the shock absorber piston rod 27 and the buffer 23 meets the standards. The preset downward pressure intensity can be adjusted according to different types of shock absorber piston rods 27 to realize welding detection of different types of shock absorbers. Compared with the method of manually operating the clamp to perform shock absorber welding detection, the welding detection device of the utility model can realize automated pressure test of the shock absorber to detect whether the shock absorber welding meets the standards, thereby improving the detection efficiency.

[0027] In an embodiment of the utility model, the driving assembly includes a driving fixed plate 1, a base plate fixing column 5, a driving member 12, a driving connecting plate 4 and a driving guide rod 2, the base plate fixing column 5 is fixed on the frame 7 and connected to the driving fixed plate 1, the driving guide rod 2 passes through the driving fixed plate 1 and is connected to the driving connecting plate 4, the driving member 12 is installed on the driving fixed plate 1 and is connected to the driving connecting plate 4, and the lower pressure head 21 is connected to the driving connecting plate 4.

[0028] By fixing the base plate fixing column 5 on the frame 7 so that the base plate fixing column 5 provides support for the driving fixing plate 1, the driving member 12 can be easily installed on the driving fixing plate 1 so that the driving member 12 is located directly above the support platform. When the driving member 12 is extended or retracted, it can drive the lower pressure head 21 to rise or fall, so that the lower pressure head 21 presses the shock absorber piston rod 27 placed on the clamping assembly to detect the welding firmness between the shock absorber piston rod 27 and the buffer 23.

[0029] By connecting the driving guide rod 2 between the driving connecting plate 4 and the driving fixed plate 1, and passing the driving guide rod 2 through the driving fixed plate 1, and connecting the output shaft of the driving member 12 to the driving connecting plate 4, the driving connecting plate 4 can be driven to move synchronously when the driving member 12 is extended or retracted, so as to ensure that the output shaft of the driving member 12 moves in a straight line under the action of the driving guide rod 2, and prevent the output shaft of the driving member 12 from deviating from the straight line direction when extending or retracting.

[0030] In the above embodiment, the driving member 12 includes any one of a pneumatic cylinder, an electric cylinder, and a hydraulic cylinder. The pressure head 21 is connected to the driving member 12 through the driving connecting plate 4 so that the pressure head 21 moves synchronously with the driving connecting plate 4. When the driving connecting plate 4 descends, the pressure head 21 can press the shock absorber piston rod 27 to realize welding detection of the shock absorber.

[0031] In an embodiment of the utility model, the detection component includes a pressure sensor and a displacement sensor 19. The pressure sensor is installed on the driving connecting plate 4 to detect the pressure of the lower pressure head 21 pressing the shock absorber piston rod 27. The displacement sensor 19 is installed on the driving connecting plate 4 to detect the displacement of the driving member 12.

[0032] By arranging a displacement sensor 19 on the driving connecting plate 4, the displacement of the driving member 12 can be detected by the displacement sensor 19, and the welding performance of the shock absorber can be judged by the change in the displacement data. By installing a pressure sensor on the driving connecting plate 4, when the lower pressure head 21 presses the shock absorber piston rod 27, the pressure sensor can sense the pressure received by the driving connecting plate 4, that is, the pressure of the lower pressure head 21 on the shock absorber piston rod 27, so that the welding performance of the shock absorber can be judged by the change in the pressure data from the displacement sensor 19.

[0033] In an embodiment of the present utility model, the driving assembly further comprises a floating joint 17 connected to the driving member 12 , and the pressure sensor is located between the floating joint 17 and the driving connecting plate 4 .

[0034] By connecting the floating joint 17 to the driving member 12 and locating the pressure sensor between the floating joint 17 and the driving connecting plate 4, the assembly error between the driving member 12 and the pressure sensor can be compensated under the action of the floating joint 17, stress concentration can be reduced, and the flexibility and adaptability of the system can be improved. At the same time, vibration and impact can be absorbed to protect system components from damage.

[0035] See also Figure 1 In an embodiment of the utility model, the detection component also includes a through-beam photoelectric sensor 8 and a photoelectric support rod 9, the photoelectric support rod 9 is fixed on the frame 7 on both sides of the support platform, the through-beam photoelectric sensor 8 is installed on the photoelectric support rod 9, and the height of the through-beam photoelectric sensor 8 is higher than the height of the support platform.

[0036] By fixing the photoelectric support rods 9 on the frames 7 on both sides of the support platform to provide support for the through-beam photoelectric sensors 8, the height of the through-beam photoelectric sensors 8 is higher than the height of the support platform. Since the height of the shock absorber piston rod 27 is higher than the height of the support platform when the shock absorber piston rod 27 is fixed on the support platform, the through-beam photoelectric sensors 8 can detect whether there is a shock absorber piston rod 27 on the support platform. Specifically, the through-beam photoelectric sensors 8 on both sides of the support platform emit and receive laser beams. When the shock absorber piston rod 27 is fixed on the support platform, the shock absorber piston rod 27 will block the propagation of the laser beam. At this time, the through-beam photoelectric sensors 8 The laser beam emitted by the photoelectric sensor 8 cannot be received by the opposing photoelectric sensor 8 on the opposite side, and thus it can be determined that there is a shock absorber piston rod 27 on the current support platform, and the operator can control the driving component 12 to perform a pressure test on the shock absorber. Conversely, when the shock absorber piston rod 27 is not fixed on the support platform, the laser beam emitted by the opposing photoelectric sensor 8 can be directly received by the opposing photoelectric sensor 8 on the opposite side, and thus it can be determined that there is no shock absorber piston rod 27 on the current support platform, and the operator cannot control the driving component 12 to perform a pressure test on the shock absorber, thereby improving the safety of the welding detection device and avoiding operational safety accidents.

[0037] See also Figure 3 In an embodiment of the utility model, the support platform includes an upper support block 24, a lower support block 28, a support column 29 and a clamping block. The lower support block 28 is connected to the support base 10 through the support column 29. The clamping block is connected between the upper support block 24 and the lower support block 28. The second through hole penetrates the upper support block 24, the lower support block 28 and the clamping block in the vertical direction.

[0038] By fixing the support column 29 on the support base 10 to provide support for the lower support block 28, and installing the clamping block between the upper support block 24 and the lower support block 28, so that the shock absorber piston rod 27 can be inserted into the second through hole and fixed by the clamping block. Since the buffer 23 cannot pass through the second through hole, the support effect on the buffer 23 can be achieved under the contact between the upper support block 24 and the buffer 23, so that the driving member 12 can drive the lower pressure head 21 to perform a pressure test on the shock absorber piston rod 27. Among them, a clamping groove adapted to the size of the clamping block is opened between the upper support block 24 and the lower support block 28. When the clamping block is installed in the clamping groove, the lower surface of the upper support block 24 fits with the upper surface of the lower support block 28 to increase the overall structural stability of the support platform, thereby providing stable support for the shock absorber piston rod 27.

[0039] In an embodiment of the utility model, the support base 10 includes a tooling base plate 31, a tooling adjustment plate 30, a first fixed plate 33, a second fixed plate 34, a first adjusting bolt 32 and a second adjusting bolt 35. The first fixed plate 33 and the second fixed plate 34 are fixed to the frame 7 on adjacent two side edges of the tooling base plate 31. The tooling base plate 31 is arranged on the frame 7. The tooling adjustment plate 30 is arranged on the tooling base plate 31. The first adjusting bolt 32 passes through the first fixed plate 33 and is connected to the tooling base plate 31. The second adjusting bolt 35 passes through the second fixed plate 34 and is connected to the tooling adjustment plate 30.

[0040] By fixing the first fixing plate 33 and the second fixing plate 34 on the frame 7 on the adjacent sides of the tooling base plate 31 respectively, and passing the first adjusting bolt 32 through the first fixing plate 33 to connect with the side of the tooling base plate 31, and passing the second adjusting bolt 35 through the second fixing plate 34 to connect with the side of the tooling adjustment plate 30, the position of the first fixing plate 33 can be adjusted under the adjustment of the first adjusting bolt 32, and the position of the second fixing plate 34 can be adjusted under the adjustment of the second adjusting bolt 35, thereby adjusting the installation position of the shock absorber piston rod 27, so that the driving member 12 can drive the lower pressure head 21 to perform a pressure test on the shock absorber.

[0041] In the embodiment of the present utility model, the first through hole penetrates the tooling bottom plate 31 and the tooling adjustment plate 30 along the vertical direction.

[0042] Since the first through hole passes through the tooling bottom plate 31 and the tooling adjustment plate 30 in the vertical direction, when the driving member 12 drives the lower pressure head 21 to perform a pressure test on the shock absorber, the lower pressure head 21 can press the top of the shock absorber piston rod 27, so that the bottom of the shock absorber piston rod 27 is not blocked by foreign objects, thereby facilitating the driving member 12 to drive the lower pressure head 21 to perform a pressure test on the piston rod, thereby improving the accuracy of the test results.

[0043] See also Figure 2 In an embodiment of the utility model, the driving component also includes an upper limit switch 11 and a lower limit switch 13 for detecting the stroke of the driving member 12, the upper limit switch 11 is arranged at the top end of the driving member 12, and the lower limit switch 13 is arranged at the low end of the driving member 12.

[0044] By respectively arranging an upper limit switch 11 and a lower limit switch 13 at the top and the bottom of the driving member 12, the upper displacement amount of the driving member 12 can be detected under the action of the upper limit switch 11, and the driving member 12 is controlled to stop moving when the driving member 12 moves to the preset upper limit position. Similarly, the lower displacement amount of the driving member 12 can be detected under the action of the lower limit switch 13, and the driving member 12 is controlled to stop moving when the driving member 12 moves to the preset lower limit position, so as to ensure the safety of the welding detection device.

[0045] In an embodiment of the utility model, the welding detection device also includes a control component, which includes a mainframe, a display screen 3 and a curve screen 6. The mainframe is fixed to one side of the frame 7 and is signal-connected to the drive component and the detection component. The display screen 3 and the curve screen 6 are both arranged on the mainframe and signal-connected to the mainframe.

[0046] By setting a main machine on one side of the frame 7, and setting a display screen 3 and a curve screen 6 on the main machine, it is convenient for operators to view the driving data of the driving component through the display screen 3, and the driving data of the driving component can be compensated and modified through the main machine, so that the driving component drives the lower pressure head 21 to perform a pressure test on the shock absorber according to a preset program. It is also convenient for operators to view the displacement data of the driving member 12 detected by the displacement sensor 19 through the display screen 3, the laser beam data emitted and received by the photoelectric sensor 8, and the pressure curve data detected by the pressure sensor through the curve screen 6, thereby improving the detection intuitiveness of the welding detection device.
