Description

Technical Field

[0001] The invention relates to the field of vehicle mechanical processing, in particular to a positioning structure for a longitudinal beam of a sub-frame. Background Art

[0002] At present, the general subframe is provided with two longitudinal beams placed in a longitudinal direction, and a plurality of cross beams are placed transversely between the two longitudinal beams. In the positioning and assembly process of the special vehicle subframe, a positioning block is usually used to fix the longitudinal beam on one side of the subframe, and then the longitudinal beam on the other side is tightened by a plurality of tightening devices. Therefore, the width of the subframe after processing is directly related to the length of the cross beam. In the actual mass production process, there is a certain error between the lengths of the cross beams produced in each batch, which leads to differences in the final formed width of the subframe, reducing the processing quality of the subframe. Summary of the invention

[0003] The object of the present invention is to provide a sub-frame longitudinal beam positioning structure which can stably clamp and position the longitudinal beam of the sub-frame and ensure the processing quality of the sub-frame.

[0005] Base;

[0006] A first driving member, fixedly mounted on the base;

[0007] A rotating block, disposed at a driving end of the first driving member, wherein the first driving member drives the rotating block to rotate with one side of the rotating block as an axis;

[0008] A second driving member is fixedly mounted on the base;

[0009] The telescopic block is arranged at the telescopic end of the second driving member, and the second driving member drives the telescopic block to telescope toward the other side of the rotating block. The auxiliary frame longitudinal beam is clamped and fixed between the rotating block and the telescopic block.

[0010] In one embodiment, it also includes a rotating shaft, the rotating block is arranged on the side of the base facing away from the first driving member, the rotating shaft is passed through the base, one side of the rotating block is drivingly connected to one end of the rotating shaft, and the driving end of the first driving member is rotatably connected to the other end of the rotating shaft.

[0011] In one embodiment, a connecting rod is further included, one end of which is rotatably connected to the first driving member, and the other end of the connecting rod is connected to an end of the rotating shaft away from the rotating block. The first driving member drives the rotating shaft to rotate through the connecting rod to rotate the rotating block.

[0012] In one embodiment, the first driving member is a telescopic cylinder.

[0013] In one embodiment, the second driving member is a telescopic cylinder.

[0014] In one embodiment, a rounded structure is provided on a side of the rotating block close to the telescopic block.

[0015] In one embodiment, a platform for abutting against the longitudinal beam of the sub-frame is provided on the outer side of the telescopic block.

[0016] In one embodiment, it further includes a bracket fixed on the base, wherein the bracket is arranged on one side of the rotating block and is used to support the rotating block.

[0017] In one embodiment, the bracket includes a support plate, which is vertically arranged on the base, the support plate is located on one side of the rotating block, and a rib is provided on the side of the support plate facing away from the rotating block, and the rib is fixed between the support plate and the base.

[0018] In one embodiment, a buffer is further included, and the buffer is disposed on the support plate. The rotating block is rotated into position to abut against the buffer.

[0019] When the longitudinal beam of the sub-frame is clamped and fixed by the above-mentioned longitudinal beam positioning structure of the sub-frame, the rotating block is in the initial position, that is, the rotating block is parallel to the longitudinal beam. At the same time, the telescopic block is in a retracted state. The longitudinal beam of the sub-frame is inserted into the above-mentioned longitudinal beam positioning structure of the sub-frame, and the first driving member works to drive the rotating block to rotate.

Then, the second driving member works to drive the telescopic block to extend toward the longitudinal beam and press the longitudinal beam. The rotating block and the telescopic block cooperate with each other to achieve the positioning and pressing of the longitudinal beam. Therefore, the above-mentioned longitudinal beam positioning structure of the sub-frame can clamp and fix a longitudinal beam alone, and the fixing of the left and right longitudinal beams of the sub-frame can be achieved by multiple above-mentioned longitudinal beam positioning structures of the sub-frame. The two longitudinal beams of the sub-frame are fixed in position, which determines the width of the sub-frame, so that the width of the sub-frame is not limited by the length of the crossbeam. Therefore, even if there is an error in the length of the crossbeam, it will not cause the width of the sub-frame to fail to meet the requirements.

DETAILED DESCRIPTION

[0022] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0023] See also Figure 1 The present invention provides a sub-frame longitudinal beam positioning structure 10. The sub-frame longitudinal beam positioning structure 10 is used to fix the longitudinal beams on the left and right sides of the sub-frame to facilitate the installation and processing of the sub-frame. The sub-frame longitudinal beam positioning structure 10 includes a base 11, a first driving member 12, a rotating block 13, a second driving member 14 and a telescopic block 15.

[0024] The base 11 is a plate-like structure. The base 11 is used to carry the first driving member 12, the rotating block 13, the second driving member 14 and the telescopic block 15. In addition, a screw hole 111 is provided on the base 11. The base 11 is fixedly connected to an external support platform by passing a bolt through the screw hole 111.

[0025] The first driving member 12 is fixedly disposed on the base 11 . The side of the base 11 facing the auxiliary frame is an upper surface 112 , and the side of the base 11 facing away from the auxiliary frame is a lower surface 113 . The first driving member 12 is disposed on the lower surface 113 of the base 11 .

[0026] The rotating block 13 is disposed on the driving end of the first driving member 12. The first driving member 12 drives the rotating block 13 to rotate with one side of the rotating block 13 as an axis.

[0027] The second driving member 14 is fixedly mounted on the base 11. The second driving member 14 is disposed on the upper surface of the base 11. The first driving member 12 and the second driving member 14 are respectively disposed on two side surfaces of the base 11, which can reduce the area occupied by the first driving member 12 and the second driving member 14 on the base 11, so that the volume of the sub-frame longitudinal beam positioning structure 10 is smaller. In other embodiments, the first driving member 12 and the second driving member 14 can also be located on the same side surface of the base 11 at the same time.

[0028] The telescopic block 15 is disposed at the driving end of the second driving member 14 . The second driving member 14 drives the telescopic block 15 to telescope toward the other side of the rotating block 13 . The auxiliary frame longitudinal beam is clamped and fixed between the rotating block 13 and the telescopic block 15 .

[0029] When the longitudinal beam of the sub-frame is clamped and fixed by the above-mentioned longitudinal beam positioning structure 10, the rotating block 13 is in the initial position, that is, the rotating block 13 is parallel to the longitudinal beam. At the same time, the telescopic block 15 is in a retracted state. The longitudinal beam of the sub-frame is inserted into the above-mentioned longitudinal beam positioning structure 10 of the sub-frame, and the first driving member 12 works to drive the rotating block 13 to rotate. When the rotating block 13 is perpendicular to the longitudinal beam, the first driving member 12 stops and the rotating block 13 stops rotating. Then, the second driving member 14 works to drive the telescopic block 15 to extend toward the longitudinal beam and press the longitudinal beam. The rotating block 13 and the telescopic block 15 cooperate with each other to achieve the positioning and pressing of the longitudinal beam. Therefore, the above-mentioned longitudinal beam positioning structure 10 of the sub-frame can clamp and fix a longitudinal beam alone, and the left and right longitudinal beams of the sub-frame can be fixed by multiple above-mentioned longitudinal beam positioning structures 10 of the sub-frame. The two longitudinal beams of the sub-frame are fixed in position, which determines the width of the sub-frame, so that the width of the sub-frame is not limited by the length of the crossbeam. Therefore, even if there is an error in the length of the cross beam, it will not cause the width of the sub-frame to fail to meet the requirements. The above-mentioned sub-frame longitudinal beam positioning structure 10 ensures the processing quality of the sub-frame.

[0030] Specifically in this embodiment, the sub-frame longitudinal beam positioning structure 10 further includes a bracket 16 fixedly disposed on the base 11. The bracket 16 is disposed on one side of the rotating block 13 and is used to support the rotating block 13.

[0031] The bracket 16 includes a support plate 161. The support plate 161 is vertically arranged on the base 11, and the support plate 161 is located on one side of the rotating block 13. A rib plate 162 is provided on the side of the support plate 161 facing away from the rotating block 13. The rib plate 162 is triangular. The rib plate 162 is fixedly arranged between the support plate 161 and the base 11. The rib plate 162 can strengthen the strength of the support plate 161. When the rotating block 13 and the telescopic block 15 are pressed against the longitudinal beam, the support plate 161 can ensure the supporting strength of the rotating block 13.

[0032] The sub-frame longitudinal beam positioning structure 10 further includes a rotating shaft 17. The bracket 16 further includes a U-shaped frame 163 for mounting the rotating shaft 17. The U-shaped frame 163 is disposed on the side of the support plate 161 facing the rotating block 13. The rotating shaft 17 is penetrated on the base 11, and the portion of the rotating shaft 17 located above the upper surface of the base 11 is positioned by the U-shaped frame. The rotating shaft 17 is rotatably connected to the U-shaped frame 163.

[0033] The rotating block 13 is disposed on the side of the base 11 facing away from the first driving member 12, that is, the rotating block 13 is disposed on the upper surface of the base 11. One side of the rotating block 13 is drivingly connected to the rotating shaft 17. Therefore, when the rotating shaft 17 rotates, the rotating block 13 is driven to rotate. The driving end of the first driving member 12 is rotatably connected to the other end of the rotating shaft 17. Thus, the first driving member 12 can drive the rotating shaft 17 to rotate.

[0034] Specifically in this embodiment, the first driving member 12 is a telescopic cylinder. The sub-frame longitudinal beam positioning structure 10 also includes a connecting rod 18. The connecting rod 18 and the first driving member 12 are both located on the lower surface of the base 11. One end of the connecting rod 18 is connected to the driving end of the first driving member 12, and the other end of the connecting rod 18 is connected to the end of the rotating shaft 17 away from the rotating block 13. When the driving end of the first driving member 12 is telescopic, one end of the connecting rod 18 is driven to rotate around the other end of the connecting rod 18. In addition, the rotation of the connecting rod 18 drives the rotating shaft 17 to rotate, so that the rotating block 13 rotates. When the rotating block 13 cooperates with the telescopic block 15 to clamp the longitudinal beam, the first driving member 12 can maintain an extended state, and the torque of the rotating block 13 to clamp the longitudinal beam is large enough.

[0035] In addition, the sub-frame longitudinal beam positioning structure 10 further includes a buffer 19. The buffer 19 is disposed on the support plate 161, and the rotating block 13 rotates to a position to abut against the buffer 19. When the rotating block 13 rotates to a position parallel to the support plate 161, the buffer 19 can prevent the rotating block 13 from colliding with the support plate 161, damaging the rotating block 13 and the support plate 161, and affecting the service life of the sub-frame longitudinal beam positioning structure 10. Specifically, the buffer 19 is a plastic part.

[0036] The stroke of the first driving member 12 can rotate the rotating shaft 17 by 90 degrees. That is, the telescopic stroke of the first driving member 12 is √2 times the length of the rotating radius of the connecting rod 18, so that the rotating shaft 17 can reciprocate by 90 degrees.

[0037] In other embodiments, the first driving member 12 may also be a rotary cylinder or a rotary motor, that is, the first driving member 12 can directly drive the rotating shaft 17 or the rotating block 13 to rotate.

[0038] A rounded corner structure 131 is provided on one side of the rotating block 13 close to the telescopic block 15. The rounded corner structure 131 is used to abut against the longitudinal beam of the subframe. When the rotating block 13 rotates, the rotating block 13 and the longitudinal beam come into contact with each other, and the rounded corner structure 131 can reduce the friction between the rotating block 13 and the longitudinal beam, making it easier for the rotating block 13 to rotate.

[0039] Specifically in the present embodiment, the second driving member 14 is a telescopic cylinder. The telescopic block 15 is disposed at the telescopic end of the second driving member 14. A platform 151 for contacting the longitudinal beam of the subframe is disposed on the outer side of the telescopic block 15. The platform 151 and the rounded structure of the rotating block 13 are arranged opposite to each other and are located on the same plane. When the rotating block 13 and the telescopic block 15 clamp the longitudinal beam, the rounded structure 131 and the platform 151 can be completely opposite to each other, so that the rotating block 13 and the telescopic block 15 can stably clamp the longitudinal beam. In other embodiments, the second driving member 14 can also be a telescopic motor.

[0040] The invention also provides a subframe positioning system.

[0041] A subframe positioning system includes four of the above-mentioned subframe longitudinal beam positioning structures 10. The four subframe longitudinal beam positioning structures 10 are distributed in a rectangular shape and clamp one end of the longitudinal beam of the subframe respectively. The first driving members 12 of the subframe longitudinal beam positioning structures 10 are all located between the two longitudinal beams, and the rotating block 13 is located on the outside of the longitudinal beam relative to the first driving member 12.

[0042] In the above-mentioned sub-frame positioning system, two longitudinal beams of the sub-frame are fixed by the four above-mentioned sub-frame longitudinal beam positioning structures 10. Since each of the above-mentioned sub-frame longitudinal beam positioning structures 10 is independent of each other, and each of the above-mentioned sub-frame longitudinal beam positioning structures 10 fixes one end of the longitudinal beam, it is ensured that the distance between the two longitudinal beams meets the processing requirements.

[0043] Therefore, the subframe positioning system fixes the two longitudinal beams of the subframe to ensure that the width of the subframe meets the requirements, thereby ensuring the processing quality of the subframe.

[0044] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
