[0002] The column is an important part of the vehicle body structure and plays a key role in ensuring vehicle safety, improving handling and supporting the vehicle body structure. After the column is produced, the sliding force of the column needs to be tested and adjusted.

[0003] To ensure the quality of the tubing, the test of sliding force includes the test of its average force, differential force and reversing force. If the test fails, it needs to be adjusted and tested again until it passes. Although this test adjustment method meets the needs of sliding force testing, there are many test data and it needs to be repeated many times. In addition, the adjustment of the tubing is completed by manually turning the adjustment screw plug. Multiple data testing, repeated execution and manual participation seriously affect the efficiency of the tubing test link.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0010] A further technical solution is that the end of the positioning pin extending into the assembly hole is tapered.

[0011] Its further technical solution is that the adjustment assembly also includes a transverse electric cylinder module, an adjustment frame and a vertical electric cylinder module; the adjustment frame is arranged on the sliding part of the transverse electric cylinder module; the vertical electric cylinder module is arranged on the adjustment frame, and the tightening shaft is arranged on the sliding part of the vertical electric cylinder module; the driving device is arranged on the adjustment frame.

[0012] A further technical solution is that a clamp seat is also provided on the frame, and a positioning block and a proximity sensor are provided on the clamp seat; the pipe column is provided on the clamp seat; the positioning block contacts the outer surface of the pipe column, and the proximity sensor tests the clamping position of the pipe column.

[0013] A further technical solution is that a second cylinder is also provided on the clamp seat, a pressure block is provided at the telescopic end of the second cylinder, and when the pipe column is arranged on the clamp seat, the pressure block contacts the surface of the pipe column away from the clamp seat.

[0014] A further technical solution is that a slide rail is also provided on the adjustment frame, and the tightening shaft is arranged on the adjustment frame through the slide rail.

[0015] The beneficial technical effects of the present invention are as follows

[0016] (1) The test and adjustment mechanism for the pipe column in the present invention is arranged on a frame.

[0026] Embodiment 1

[0027] Figure 1 It shows a three-dimensional structural schematic diagram of a pipe column after the pipe column is clamped by a test adjustment mechanism in the first embodiment of the present invention. Figure 2 The figure shows a schematic diagram of the three-dimensional structure of the pipe column tested in the pipe column test adjustment mechanism in the first embodiment of the present invention. Figure 1 and Figure 2 , a test adjustment mechanism for a pipe column includes a frame 1, a test assembly 2 and an adjustment assembly 3. The pipe column 5 is arranged on the frame 1. The test assembly 2 includes a servo press 21 and a bracket 22, wherein the bracket 22 is connected to the telescopic end of the servo press 21, and a positioning pin 25 is arranged on the bracket 22. The telescopic movement of the servo press 21 drives the positioning pin 25, and drives the telescopic movement and sliding between the two sections of the pipe column 5. By monitoring the pressure data of the servo press 21, various data of the sliding force of the pipe column 5 can be quickly obtained. The adjustment assembly 3 includes a tightening shaft 34, and the tightening shaft 34 is connected to a driving device 35. Among them, the telescopic extrusion direction of the servo press 21 is consistent with the telescopic sliding direction of the pipe column 5. The positioning pin 25 extends into the assembly hole 52 of the pipe column 5, and a screwdriver is arranged at the end of the tightening shaft 34, and the screwdriver is connected to the adjustment screw plug 51 of the pipe column 5. While the tightening shaft 34 is driven by the driving device 35, the tightening shaft 34 is connected to the adjustment screw plug 51 of the pipe column 5 through the screwdriver. According to the sliding force data obtained by the servo press 21, the tightening shaft 34 is then driven by the driving device 35, and then the adjusting screw plug 51 is adjusted to adjust the sliding force of the pipe string 5. The principle of the test method is simple, and automatic testing and adjustment can be achieved through the control unit, which saves manpower and improves the test and adjustment efficiency of the pipe string 5.

[0028] Please refer to Figure 1 and Figure 2The test assembly 2 further includes a first cylinder 23 and a positioning plate 24. The first cylinder 23 is disposed on the bracket 22, the first cylinder 23 points to the assembly hole 52, the positioning plate 24 is disposed at the end of the telescopic end of the first cylinder 23, and the positioning pin 25 is disposed on the positioning plate 24. By controlling the telescopic movement of the first cylinder 23, the positioning pin 25 can be quickly moved away from the pipe column 5 and the positioning pin 25 can be extended into the assembly hole 52. When the pipe column 5 for test adjustment is replaced, interference between the pipe column 5 and the positioning pin 25 is avoided, and the clamping of the pipe column 5 is simplified.

[0029] Preferably, the frame 1 is also provided with a slide rail, and the bracket 22 is connected to the frame 1 via the slide rail. When the servo press 21 drives the bracket 22 to move, the slide rail can improve the stability of the movement of the bracket 22, so that the test adjustment mechanism of the pipe column 5 can run more smoothly. The end of the positioning pin 25 extending into the assembly hole 52 is tapered, which facilitates the positioning pin 25 to extend into the assembly hole 52.

[0030] Please refer to Figure 1 and Figure 2 The adjustment assembly 3 also includes a horizontal electric cylinder module 31, an adjustment frame 32 and a vertical electric cylinder module 33. The adjustment frame 32 is arranged on the sliding part of the horizontal electric cylinder module 31. The vertical electric cylinder module 33 is arranged on the adjustment frame 32, and the tightening shaft 34 is arranged on the sliding part of the vertical electric cylinder module 33. The driving device 35 is arranged on the adjustment frame 32. Through the actions of the horizontal electric cylinder module 31 and the vertical electric cylinder module 33, the height and horizontal position of the screwdriver bit can be accurately controlled, and the adjustment screw plug 51 at different positions on the pipe column 5 can be adjusted without re-clamping the pipe column 5, thereby improving the adjustment efficiency of the sliding force of the pipe column 5.

[0031] Preferably, a slide rail is also provided at the installation position of the adjustment assembly 3, and the adjustment frame 32 is connected to the slide rail at the installation position. When the lateral electric cylinder module 31 drives the adjustment frame 32 to move laterally, the slide rail at the installation position can improve the stability of the movement of the adjustment frame 32, thereby improving the stability of the operation of the test adjustment mechanism of the pipe column 5.

[0032] More preferably, a slide rail is further provided on the adjustment frame 32, and the tightening shaft 34 is provided on the adjustment frame 32 through the slide rail. Specifically, the tightening shaft 34 is fixed on the adjustment frame 32 through a bearing seat, and the bearing seat is connected to the slide rail on the adjustment frame 32. When the vertical electric cylinder module 33 drives the tightening shaft 34 to move vertically, the slide rail on the adjustment frame 32 can improve the stability of the movement of the tightening shaft 34, thereby improving the stability of the operation of the test adjustment mechanism of the pipe string 5.

[0033] Figure 3 FIG. 1 shows a three-dimensional structural diagram of a testing and adjusting mechanism for a pipe column in the first embodiment of the present invention. Figure 1 and Figure 3The frame 1 is also provided with a fixture seat 4, and the fixture seat 4 is provided with a positioning block 43 and a proximity sensor 44. The pipe column 5 is arranged on the fixture seat 4. The positioning block 43 contacts the outer surface of the pipe column 5, and the proximity sensor 44 tests the clamping position of the pipe column 5. The pipe column 5 can be placed on the fixture seat 4 according to the preset position and orientation through the positioning block 43. The contact sensor can automatically determine whether there is a pipe column 5 on the fixture seat 4, and the control unit can realize that the test component 2 and the adjustment component 3 do not work when there is no pipe column 5, thereby improving the intelligence level of the test adjustment mechanism for the pipe column 5.

[0034] Furthermore, the clamp seat 4 is also provided with a second cylinder 41, and a pressing block 42 is provided at the telescopic end of the second cylinder 41. When the pipe column 5 is arranged on the clamp seat 4, the pressing block 42 contacts the surface of the pipe column 5 away from the clamp seat 4. By contraction of the second cylinder 41, the pressing block 42 can be driven to press the pipe column 5, so as to realize the clamping of the pipe column 5 on the clamp seat 4.

[0035] The specific workflow of this embodiment is as follows:

[0036] The operator or the loading equipment places the pipe column 5 on the clamp seat 4, and quickly determines the placement position of the pipe column 5 through the positioning block 43. The second cylinder 41 contracts to drive the pressure block 42 to press the pipe column 5, completing the clamping of the pipe column 5. At this time, the proximity sensor 44 detects that the pipe column 5 is fixed on the clamp seat 4. The servo press 21 and the first cylinder 23 extend and retract to extend the positioning pin 25 into the adjustment screw plug 51 of the pipe column 5. The horizontal electric cylinder module 31 and the vertical electric cylinder module 33 are started to drive the tightening shaft 34 to extend into the adjustment screw plug 51. Then the servo press 21 extends and retracts, and drives the two sections of the pipe body of the pipe column 5 to extend and slide through the positioning pin 25, and the sliding force data of the pipe column 5 is obtained through the pressure data of the servo press 21. It is determined whether the sliding force data meets the standard. If not, the driving device 35 drives the tightening shaft 34 to rotate, driving the adjusting screw plug 51 to rotate, adjusting the torque and angle of the adjusting screw plug 51, and then retesting the sliding force of the pipe string 5 and making a judgment until the sliding force data meets the standard, thereby completing the testing and adjustment of the pipe string 5.

[0037] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
