Description

Technical Field

[0001] The utility model relates to the technical field of Yuanbao beam installation, in particular to a vehicle Yuanbao beam fixing structure. Background Art

[0002] The automobile's front subframe, also known as the automobile's front subframe, is part of the automobile's suspension system and is mainly located at the front of the vehicle. It is a device used to fix the suspension and increase the rigidity of the vehicle body. All cars with a load-bearing body design are equipped with subframes, including front and rear subframes. The automobile's front subframe usually has the function of lifting and fixing the engine and gearbox to ensure the stability and safety of these core components during the car's driving. In the process of relatively fixing the front subframe and the vehicle chassis, bolts, wrenches, and support frames are required to cooperate with each other.

[0003] In the prior art, before disassembling or installing the Yuanbao beam, it is necessary to fix it with a support frame so that it can be docked with the vehicle chassis under the support of the support frame, and then bolts are used to fix the Yuanbao beam and the vehicle chassis to each other using tools such as wrenches.

[0004] In the current existing technology, most Yuanbao beams are symmetrical structures with different shapes, and their centers often have a certain degree of inclination, while the support frames are mostly integral structures. This makes it impossible to ensure that the front and rear positions of the Yuanbao beams are completely aligned with the vehicle chassis after the Yuanbao beams are supported. The inclination angle of the Yuanbao beams needs to be neutralized under the action of gaskets before the Yuanbao beams can be matched with the frame. The process of adjusting the gaskets will take a certain amount of time, which will affect the efficiency of disassembly and assembly of the Yuanbao beams.

[0005] Therefore, in order to solve the above problems, a vehicle ingot beam fixing structure is proposed. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that most Yuanbao beams are symmetrical structures with different shapes, and their centers often have a certain inclination, while the support frames are mostly integral structures, which makes it impossible to ensure that the front and rear positions of the Yuanbao beams are completely consistent with the vehicle chassis after the Yuanbao beams are supported. The inclination angle of the Yuanbao beams needs to be neutralized under the action of gaskets before the Yuanbao beams can be matched with the frame. The process of adjusting the gaskets will take a certain amount of time, which will affect the efficiency of disassembly and assembly of the Yuanbao beams. A vehicle Yuanbao beam fixing structure is proposed.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the present invention describes a vehicle ingot beam fixing structure, including a center plate, a supporting assembly installed at the bottom of the center plate, a supporting plate installed at the top center of the center plate through a bracket, a first track fixedly connected to one side of the bottom center of the supporting plate, a trapezoidal bracket installed on the bottom surface of the center plate, the trapezoidal bracket is located at the lower projection of the first track, a second track is opened at the center of the inclined wall of the trapezoidal bracket, an angular screw rod is vertically installed at the center of the side wall of the center plate through a bearing, the external thread of the angular screw rod is fixedly connected to a first threaded sleeve, the outer wall of the first threaded sleeve is clamped with a vertical frame, and the shaft rods at both ends of the vertical frame are respectively slidably installed between the inner walls of the first track and the second track.

[0015] Beneficial effects of the utility model:

[0016] 1. In the present invention, the supporting plate is installed by the linkage bracket on the median plate, so that the relative angle between the median plate and the supporting plate can be changed within a certain range. After the Yuanbao beam is placed on the supporting plate, the first motor is started, and the relative position of the first threaded sleeve on it is changed under the rotational force of the first threaded sleeve, thereby changing the relative position of the vertical frame between the first track and the second track on the trapezoidal bracket, so as to achieve the purpose of changing the relative angle between the median plate and the supporting plate, adapt to the inclination at the support of the Yuanbao beam, and require the adjustment and cooperation of the gasket during the process of supporting and installing the Yuanbao beam by the device, thereby improving the support efficiency of the device for the Yuanbao beam and assisting in improving the disassembly and assembly efficiency of the Yuanbao beam.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Specific examples are given below.

[0029] See also Figure 1 - Figure 6The utility model provides a vehicle ingot beam fixing structure, including a center plate 1, a support assembly 2 is installed at the bottom of the center plate 1, a support plate 3 is installed at the top center of the center plate 1 through a bracket, a first track 31 is fixed to one side of the bottom center of the support plate 3, a trapezoidal bracket 4 is installed on the bottom surface of the center plate 1, the trapezoidal bracket 4 is located at the lower projection of the first track 31, a second track 41 is opened at the center of the inclined wall of the trapezoidal bracket 4, and the side wall center of the center plate 1 is vertically connected to the center plate 1 through a bearing. An angle screw 5 is installed, and the external thread of the angle screw 5 is fixedly connected to the first threaded sleeve 51. The outer wall of the first threaded sleeve 51 is clamped with a vertical frame 52. The shafts at both ends of the vertical frame 52 are respectively slidably installed between the inner walls of the first track 31 and the second track 41. One end of the trapezoidal bracket 4 is vertically fixedly connected to a positioning plate 42. One side of the positioning plate 42 is fixedly connected to one end of the angle screw 5 through a bearing. A first motor 53 is installed on the other side of the positioning plate 42. The output shaft of the first motor 53 passes through the positioning plate 4 2 is connected to the axis of the deflection screw rod 5, and the support assembly 2 supports the center plate 1 and the supporting plate 3 as a whole. The central bracket connection between the center plate 1 and the supporting plate 3 allows the relative angle between the center plate 1 and the supporting plate 3 to be changed within a certain range. In addition, the supporting plate 3 serves as the main structure for contact support at the center of the Yuanbao beam. The change of its relative angle can adapt to the change of the inclination of the bottom of the Yuanbao beam within a certain range. When the inclination of the supporting plate 3 needs to be adjusted, the first motor 53 installed on one side of the positioning plate 42 is started. As the deflection screw rod 5 rotates, the relative position of the first threaded sleeve 51 on the deflection screw rod 5 changes, thereby driving the relative position of the vertical frame 52 to change. In addition, the first track 31 and the second track 41 are not parallel, thereby causing the relative position of the vertical frame 52 to change, which can change the relative angle between the supporting plate 3 and the center plate 1 within a certain range, so that the supporting plate 3 adapts to the inclination angle of the Yuanbao beam to change the support angle;

[0030] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the top surface of the center plate 1 is symmetrically provided with a clearance opening 11, and the bottom surface of the center plate 1 is symmetrically fixed with a linkage bracket 12. The support assembly 2 includes a movable base plate 21, and a support link 22 is symmetrically installed above the movable base plate 21. One end of the two support links 22 is respectively clamped with the two linkage brackets 12, and one end of the support link 22 is clamped with an adjusting slider 23, which is slidably installed in the top groove of the movable base plate 21. The center plate 1 cooperates with the support assembly 2 through the linkage bracket 12, so that the support assembly 2 supports the center plate 1 and the supporting plate 3 as a whole. When the two adjusting sliders 23 are adjusted to approach each other in the movable base plate 21, the relative angle between the support links 22 can be changed, so as to achieve the purpose of controlling the lifting and lowering of the center plate 1 as a whole within a certain range, and when the support assembly 2 is lifted as a whole, the clearance opening 11 is exposed, which is convenient for the bolt connection after the ingot beam is matched with the vehicle chassis;

[0031] like Figure 5 and Figure 6 As shown, the side walls of the two adjusting sliders 23 are fixedly connected with second threaded sleeves 231, and two bidirectional screw rods 24 are installed in the two second threaded sleeves 231. One end of the bidirectional screw rod 24 is fixedly connected to a screw rod bracket 241 through a bearing. The bottom of the screw rod bracket 241 is fixedly connected to one end of the top surface of the movable base plate 21, and a second motor 25 is installed on the outside of one end of the movable base plate 21 through a bracket. The output shaft of the second motor 25 is connected to the axis of the bidirectional screw rod 24, and the bidirectional screw rod 24 is installed above the supporting plate 3 through the cooperation of the screw rod bracket 241 and the second motor 25. After the angle of the supporting plate 3 itself is adjusted, the Yuanbao beam is placed above the support assembly 2, and the second motor 25 is started. As the adjusting slider 23 rotates, the second threaded sleeve 231 can approach each other under the action of the thread of the adjusting slider 23, thereby raising the center plate 1 as a whole, and turning off the second motor 25 after it is raised to the point where the Yuanbao beam fits the vehicle chassis. At this time, the Yuanbao beam and the vehicle chassis are fixed to each other by bolts;

[0032] Working principle: When the inclination of the supporting plate 3 needs to be adjusted, the first motor 53 installed on one side of the positioning plate 42 is started, and the deflection screw 5 rotates, and the relative position of the first threaded sleeve 51 on the deflection screw 5 changes, thereby driving the vertical frame 52 to change its relative position. In addition, the first track 31 and the second track 41 are not parallel, which causes the change in the relative position of the vertical frame 52, which can change the relative angle between the supporting plate 3 and the middle plate 1 within a certain range, so that the supporting plate 3 can adapt to the inclination angle of the ingot beam and change the support angle. The middle plate 1 cooperates with the support assembly 2 through the linkage bracket 12, so that the support assembly 2 supports the middle plate 1 and the supporting plate 3 as a whole. When the two adjusting sliders 23 are adjusted to be close to each other in the movable base plate 21, The relative angle between the support links 22 can be changed to achieve the purpose of controlling the overall lifting and lowering of the median plate 1 within a certain range, and the opening 11 is exposed when the support assembly 2 is raised as a whole, which is convenient for the bolt connection after the Yuanbao beam is matched with the vehicle chassis. The bidirectional screw 24 is installed above the support plate 3 through the cooperation of the screw bracket 241 and the second motor 25. After the angle of the support plate 3 itself is adjusted, the Yuanbao beam is placed above the support assembly 2, and the second motor 25 is started. The adjusting slider 23 rotates, and the second threaded sleeve 231 can approach each other under the action of the thread of the adjusting slider 23, thereby raising the median plate 1 as a whole, and turning off the second motor 25 after it is raised to the point where the Yuanbao beam is matched with the vehicle chassis. At this time, the Yuanbao beam and the vehicle chassis are fixed to each other by bolts.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
