Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary fixing during automobile maintenance, in particular to a universal positioning module of a beam correction instrument. Background Art

[0002] The beam straightener applies a force opposite to the direction of the collision to the vehicle body through a stretching system, thereby restoring the deformation of the vehicle body. The positioning module of the beam straightener is an important component to ensure vehicle stability and accurate measurement during the body correction process. However, the current general positioning module is fixed in position, so the beam straightener cannot be applied to various vehicle models.

[0003] The Chinese utility model patent with authorization announcement number CN201421314Y discloses a special measuring tool for a beam aligner. Paragraph

[0022] of the specification discloses three pairs of measuring tools for front subframe mounting points and two pairs of measuring tools for rear subframe mounting points. A sleeve with positioning holes is fixed on a fixed base plate, and a measuring head is inserted into the sleeve. The measuring head consists of a connecting column and a vehicle body connecting plate. The sleeve and the connecting column are connected by a positioning pin. The end of the connecting column is connected to the vehicle body connecting plate. The fixed base plate is fixed to a reference beam by bolts. The reference beam has multiple bolt holes, which are installed according to different hole positions. In the above-mentioned disclosed solution, the connecting column can be adjusted in height in the vertical direction relative to the sleeve to meet the fixing requirements of different vehicle heights. At the same time, the horizontal position can be roughly adjusted by changing the position of the reference beam relative to the platform. However, since the solution can only rely on adding bolt holes for coarse position adjustment and cannot be fine-tuned, it cannot meet the fixing requirements when there are slight differences in vehicles. As a result, the scope of vehicles applicable to the beam aligner is still limited and cannot be truly universal. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 To the attached Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] A universal positioning module for a beam correction instrument, such as Figure 1 — Figure 2As shown, it includes a positioning slide 1 and a support assembly 2. The positioning slide 1 and the support assembly 2 are detachably connected. The positioning slide 1 is connected to the crossbeam 4 of the main platform 3. The crossbeam 4 is provided with a plurality of mounting holes 32 connected to the positioning slide 1 in the length direction. The positioning slide 1 can adjust its position on the crossbeam 4 arbitrarily according to the position of the vehicle chassis fixing point. The positioning slide 1 and the crossbeam 4 are connected by bolts. In order to be suitable for more vehicle models, the main platform 3 is also provided with a plurality of groups of connection holes for fixing the crossbeam 4 in the length direction. The position of the crossbeam 4 relative to the main platform 3 can also be adjusted according to the position of the vehicle chassis fixing point.

[0025] The support assembly 2 comprises a support column 5 and a lifting column 6. The support column 5 is detachably connected to the positioning slide 1. In this embodiment, the support column 5 and the positioning slide 1 are connected by bolts. The lifting column 6 is nested within the support column 5 and can be displaced vertically. The top of the lifting column 6 is provided with a positioning assembly 7. The positioning head 26 of the positioning assembly 7 can limit and fix the vehicle chassis.

[0026] like Figure 3 As shown, in order to further improve the versatility of the device, the position of the positioning component 7 can be further adjusted to meet the positioning needs of different vehicle models. The positioning slide 1 includes a base 8, an intermediate slide 9 and an upper slide 10. Figure 1 As shown in the center coordinate system, the base 8 and the middle slide 9 are connected by the first slide rail 11 to achieve displacement along the X-axis direction, and the middle slide 9 and the upper slide 10 are connected by the second slide rail 12 to achieve displacement along the Y-axis direction. The positioning slide 1 is provided with scales in the X-axis direction and the Y-axis direction respectively for measuring the exact position of the X-axis and Y-axis directions, thereby achieving precise control of the displacement amount.

[0027] The base 8 and the upper slide 10 are respectively provided with a first oblong hole 13 and a second oblong hole 15 for connection. The intermediate slide 9 is provided with a through hole 16 that matches the aperture of the first oblong hole 13 and the second oblong hole 15. The first oblong hole 13 and the second oblong hole 15 are positioned in a "cross" shape. After the X-axis and Y-axis positions are adjusted, the base 8, the intermediate slide 9, and the upper slide 10 can be fastened together by tightening the nut 18 at the end of the bolt 17 that passes through the first oblong hole 13, the second oblong hole 15, and the through hole 16, effectively preventing positional deviation. To prevent the nut 18 from interfering with the crossbeam 4, the base 8 is further provided with a groove 14 for accommodating the nut 18. After being tightened, the nut 18 is located in the groove 14 and does not protrude from the contact surface between the base 8 and the crossbeam 4.

[0028] The support column 5 comprises a base plate 19 connected to the positioning slide 1 and a sleeve 20 that engages the lifting column 6. The sleeve 20 and the lifting column 6 are provided with a number of spaced-apart matching holes 21, each containing a removable stopper pin 22. The number of matching holes 21 on the sleeve 20 and the lifting column 6 can be equal or unequal. Once the lifting column 6 is vertically positioned, as long as it can be stopped by the matching holes 21, the function is met. To increase support strength, a reinforcement plate 23 connected to the base plate 19 is provided on the outside of the sleeve 20.

[0029] like Figure 4 As shown, the positioning assembly 7 includes an adapter plate 24, a conversion seat 25 and a positioning head 26 that are detachably connected to the lifting column 6. The adapter plate 24 is connected to the top of the lifting column 6 by bolts. A positioning hole 27 for installing the conversion seat 25 is provided on the adapter plate 24. One end of the conversion seat 25 is provided with a limiting shaft 29 that is compatible with the positioning hole 27 to ensure that the conversion seat 25 and the positioning hole 27 are accurately positioned without relative displacement. The other end of the conversion seat 25 is provided with a connecting shaft 30 connected to the positioning head 26, and the end of the limiting shaft 29 is provided with a locking block 28 connected by a threaded pair. In this embodiment, the limiting shaft 29 is provided with an internal threaded hole, and the locking block 28 has an external thread. The locking block 28 locks the limiting shaft 29 through the thread. Of course, the limiting shaft 29 can also adopt an external thread, and the locking block 28 has an internal thread that matches it, and the two cooperate to lock. One end of the positioning head 26 is connected to the connecting shaft 30 through a threaded pair, so that the positioning head 26 can be precisely adjusted in the vertical height direction. In order to accurately measure the precise adjustment height value, the connecting shaft 30 is also provided with a vertical scale 31 for measuring the adjustment size. The other end of the positioning head 26 is provided with a threaded interface connected to the automobile chassis. The threaded interface can be in the form of an internal thread that matches the automobile chassis or an external thread.

[0030] Working principle of this device: According to the model of the vehicle to be repaired, the position of the crossbeam 4 on the main platform 3 is preliminarily determined, and the number of positioning modules and their positions on the crossbeam 4 are preliminarily determined. The vehicle to be repaired is placed on the main platform 3, and the support assembly 2 is displaced along the X-axis and Y-axis through the first slide rail 11 and the second slide rail 12 of the positioning slide 1, so that the positioning head 26 is aligned with the fixed point of the vehicle to be repaired in the vertical direction, and the bolt 17 is tightened to fix the position, and the height of the lifting column 6 is preliminarily adjusted. After the height of the lifting column 6 is adjusted, the limit pin 22 is inserted into the adapter hole 21 for limiting the position, and the positioning head 26 is rotated to precisely adjust the height of the positioning head 26 through the threaded pair until it is effectively fixed to the fixed point of the vehicle to be repaired. The positioning head 26 of this device can accurately adjust the position within three coordinates to meet the positioning requirements of different vehicle maintenance processes, and has stronger versatility.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
