Description

Technical Field

[0001] This utility model relates to the field of lightweight aluminum alloy inner tubes for connecting new energy vehicle chassis, specifically a tooling fixture for connecting lightweight aluminum alloy inner tubes for new energy vehicle chassis. Background Technology

[0002] The requirements for lightweighting in new energy vehicles are becoming increasingly stringent. It's not enough to simply replace steel with aluminum alloys or nylon; for individual components, structural weight reduction must be considered while maintaining the locking force of nuts. For these reasons, we must continuously upgrade the lightweight structure of existing products to meet customer demands. The lightweight aluminum alloy inner tube connecting the chassis of new energy vehicles is a high-performance aluminum alloy tubular structural component used in the chassis system. It is primarily used to achieve lightweight connections between chassis components while ensuring structural strength, rigidity, and energy absorption capacity. During the processing of the lightweight aluminum alloy inner tube connecting the chassis of new energy vehicles, workers utilize tooling fixtures for auxiliary operations.

[0003] However, current tooling fixtures still have some shortcomings. For example, a clamping tool for welding nickel-titanium pipes with application number 202121907332.X has not fully considered the clamping structure. When using the tooling fixture to process lightweight aluminum alloy inner tubes connecting to the chassis of new energy vehicles, if the clamping structure of the tooling fixture is not fully considered, the tooling fixture will have certain limitations on the size of the inner tubes to be processed, which limits the applicability of the tooling fixture. It is not convenient for workers to change the clamping mechanism of the tooling fixture according to actual needs, and it is inconvenient for workers to use the tooling fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling fixture for connecting lightweight aluminum alloy inner tubes to the chassis of new energy vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for connecting lightweight aluminum alloy inner tubes to a new energy vehicle chassis, comprising a fixed base, a limiting frame, and limiting components. A drive motor is installed on one side of the fixed base, and the output shaft of the drive motor is fixedly connected to a rotating rod via a coupling. A bidirectional screw is welded to one end of the rotating rod, and sliding blocks are rotatably connected to both ends of the bidirectional screw via threads. The limiting frame is welded to the top of the sliding blocks, and a locking component is engaged with the top of the limiting frame. Limiting components are provided on both sides of the limiting frame. The limiting component is welded to the top of the locking component, and an anti-slip pad is fixedly adhered to the inner wall of the limiting component. A blocking component is provided on one side of the surface of the limiting component.

[0006] Furthermore, both the rotating rod and the bidirectional screw are rotatably connected inside the fixed base, and the sliding block is engaged and slidably connected to both sides inside the fixed base.

[0007] Furthermore, the limiting component includes a connecting frame, a pull member, a fixing rod, a limiting plate, a return spring, and a locking rod, and the connecting frame is welded to both sides of the limiting frame, and a pull member is provided on one side of the connecting frame.

[0008] Furthermore, a fixing rod is welded to one side of the pulling member, and a limit plate is welded to the other end of the fixing rod. The limit plate is located inside the connecting frame, and a return spring is provided on one side of the limit plate.

[0009] Furthermore, the reset spring is located on the outside of the fixed rod, and a locking rod is welded to the other side of the limiting plate. The locking rod is connected through the side wall of the connecting frame, and the other end of the locking rod is connected through the limiting frame and engaged with the locking component.

[0010] Furthermore, the blocking assembly includes a limiting block, a blocking member, a rotating member, a fixing block, a locking block, and a blocking strip, with the limiting block fixedly connected to one side of the surface of the limiting member, and the blocking member rotatably connected to the outer side of the limiting block.

[0011] Furthermore, a rotating member is provided on one side below the blocking member, and one end of the rotating member is rotatably connected to the surface of the limiting member. A fixing block is provided on one side of the rotating member, and the fixing block is welded to the surface of the limiting member.

[0012] Furthermore, a locking block is welded to the bottom of the fixing block, and a blocking strip is slidably connected to the fixing block through the locking block, and the blocking strip contacts the bottom of the rotating part.

[0013] This utility model provides a tooling fixture for connecting lightweight aluminum alloy inner tubes to the chassis of new energy vehicles, which has the following advantages:

[0014] 1. This utility model is equipped with a limiting component. During the processing of lightweight aluminum alloy inner tubes connecting to the chassis of new energy vehicles using tooling fixtures, after the locking component is locked into the limiting frame, the pulling component is released. Under the elastic force of the return spring, the limiting plate gradually returns to its original position, thereby locking the locking rod into the locking component. This facilitates the subsequent replacement and maintenance of the limiting component by the staff, expands the applicability of the tooling fixture, and makes it easy for the staff to replace the clamping structure according to actual needs. Moreover, the structure is tightly connected, avoiding the situation of structural loosening during the subsequent processing of the inner tube, ensuring the smooth progress of the inner tube processing, and facilitating the use of the tooling fixture by the staff.

[0015] 2. This utility model is equipped with a blocking component. During the process of using tooling fixtures to process the lightweight aluminum alloy inner tube connecting the chassis of a new energy vehicle, the blocking component blocks the end of the inner tube and is restricted between the rotating component and the fixed block. Then, the blocking strip blocks the bottom of the rotating component, which provides a certain degree of anti-slip treatment and prevents the inner tube from slipping and rotating in the clamping mechanism. It also makes it easier for the staff to position and clamp the inner tube, which is convenient for the subsequent processing needs of the inner tube and the use of tooling fixtures.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-3As shown, a tooling fixture for connecting lightweight aluminum alloy inner tubes to a new energy vehicle chassis includes a fixed base 1, a limiting frame 6, and limiting components 9. A drive motor 2 is installed on one side of the interior of the fixed base 1, and the output shaft of the drive motor 2 is fixedly connected to a rotating rod 3 via a coupling. A double-ended screw 4 is welded to one end of the rotating rod 3, and sliding blocks 5 are rotatably connected to the outer sides of both ends of the double-ended screw 4 via threads. The rotating rod 3 and the double-ended screw 4 are both rotatably connected inside the fixed base 1, and the sliding blocks 5 are engaged and slidably connected to both sides of the interior of the fixed base 1. The limiting frame 6 is welded to the top of the sliding blocks 5, and a locking component 7 is engaged and connected above the limiting frame 6. Limiting components 8 are provided on both sides of the limiting frame 6. The limiting components 8 include a connecting frame 801 and a pulling... The frame includes a component 802, a fixing rod 803, a limiting plate 804, a return spring 805, and a locking rod 806. The connecting frame 801 is welded to both sides of the limiting frame 6. A pulling component 802 is provided on one side of the connecting frame 801, and a fixing rod 803 is welded to one side of the pulling component 802. The other end of the fixing rod 803 is welded to the limiting plate 804, which is located inside the connecting frame 801. A return spring 805 is provided on one side of the limiting plate 804, which is located outside the fixing rod 803. The other side of the limiting plate 804 is welded to the locking rod 806, which is connected through the side wall of the connecting frame 801. The other end of the locking rod 806 is connected through the limiting frame 6 and engaged with the locking component 7.

[0023] The specific operation is as follows: The operator places the inner tube to be processed above the fixed base 1, and then uses the drive motor 2 to drive the rotating rod 3 to rotate, causing the double-ended screw 4 welded to the other end of the rotating rod 3 to rotate as well. This causes the sliding blocks 5, which are connected by threads on both sides of the double-ended screw 4, to engage and slide inside the fixed base 1. The engaging part 7 welded to the bottom of the limiting part 9 engages with the limiting frame 6 welded to the top of the sliding block 5. As the sliding block 5 moves, the limiting part 9 moves accordingly, thereby clamping and limiting the inner tube. In addition, the limiting frame 6 and the engaging part 7 are connected by a limiting component 8. Before engaging the engaging part 7, the operator pulls... The moving part 802 is pulled outward, causing the fixed rod 803 welded to one side of the moving part 802 to move accordingly. This causes the limiting plate 804 welded to the other end of the fixed rod 803 to press against the return spring 805 set on the outside of the fixed rod 803. The locking rod 806 welded to the other side of the limiting plate 804 retracts into the side wall of the limiting frame 6. Then, after the locking part 7 is locked into the limiting frame 6, the pulling of the moving part 802 is released. Under the elastic force of the return spring 805, the limiting plate 804 gradually returns to its original position, so that the locking rod 806 locks the locking part 7. This makes it convenient for the staff to replace and maintain the limiting part 9 and facilitates the use of the tooling fixture.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the limiting member 9 is welded to the top of the engaging member 7, and an anti-slip pad 10 is fixedly adhered to the inner wall of the limiting member 9. A blocking assembly 11 is provided on one side of the surface of the limiting member 9. The blocking assembly 11 includes a limiting block 1101, a blocking member 1102, a rotating member 1103, a fixing block 1104, an engaging block 1105, and a blocking strip 1106. The limiting block 1101 is fixedly connected to one side of the surface of the limiting member 9, and the blocking member 1102 is rotatably connected to the outer side of the limiting block 1101, thus blocking... A rotating component 1103 is provided on one side of the lower part of component 1102, and one end of the rotating component 1103 is rotatably connected to the surface of the limiting component 9. A fixing block 1104 is provided on one side of the rotating component 1103, and the fixing block 1104 is welded to the surface of the limiting component 9. A locking block 1105 is welded to the bottom of the fixing block 1104, and a blocking strip 1106 is slidably connected to the fixing block 1104 through the locking block 1105. The blocking strip 1106 is in contact with the bottom of the rotating component 1103.

[0025] The specific operation is as follows: As the sliding block 5 moves, the inner tube is gradually restricted between the limiting members 9. The anti-slip pad 10 fixedly adhered to the inner wall of the limiting member 9 can provide anti-slip treatment for the outer wall of the inner tube. The operator can use the blocking component 11 provided on one side of the surface of the limiting member 9 to block the end of the inner tube and rotate the blocking member 1102 and the rotating member 1103 provided on one side below it. This causes the blocking member 1102 to block the end of the inner tube and restrict the blocking member 1102 between the rotating member 1103 and the fixed block 1104. Then, the locking block 1105 welded to the bottom of the fixed block 1104 is used to slide the blocking strip 1106, so that the blocking strip 1106 blocks the bottom of the rotating member 1103. This facilitates the subsequent processing of the inner tube by the operator and the use of the tooling fixture.

[0026] In summary, the tooling fixture for connecting the lightweight aluminum alloy inner tube of this new energy vehicle chassis is based on... Figures 1-4The structure shown, when used to process the lightweight aluminum alloy inner tube connecting the chassis of a new energy vehicle using tooling fixtures, firstly, the operator places the inner tube to be processed above the fixed base 1. Then, the drive motor 2 drives the rotating rod 3 to rotate, causing the bidirectional screw 4 welded to the other end of the rotating rod 3 to rotate as well. This causes the sliding blocks 5, which are connected to the outer sides of the two ends of the bidirectional screw 4 by threaded rotation, to engage and slide inside the fixed base 1 on both sides. The engaging part 7 welded to the bottom of the limiting part 9 and the limiting frame welded to the top of the sliding block 5 are also connected. 6. Engagement is performed. As the sliding block 5 moves, the limiting member 9 moves accordingly, thereby clamping and limiting the inner tube. The anti-slip pad 10, fixedly adhered to the inner wall of the limiting member 9, provides anti-slip treatment to the outer wall of the inner tube. Next, the operator can use the blocking component 11 on one side of the limiting member 9 to block the end of the inner tube. The blocking component 1102 and the rotating component 1103 on its lower side are rotated, causing the blocking component 1102 to block the end of the inner tube and restrict the blocking component 1102 within the rotating component 1103. Between the fixed block 1104 and the fixed block 1104, the locking block 1105 welded to the bottom of the fixed block 1104 is used to slide the blocking strip 1106, so that the blocking strip 1106 blocks the bottom of the rotating part 1103, which facilitates the subsequent processing of the inner tube by the workers. In addition, the limiting frame 6 and the locking part 7 are connected by the limiting component 8. Before the workers lock the locking part 7, they pull the pulling part 802 outward, so that the fixed rod 803 welded to one side of the pulling part 802 moves with it, thereby making the fixed rod 803 move. The limiting plate 804 welded at the other end presses against the return spring 805 set on the outside of the fixing rod 803, and the locking rod 806 welded on the other side of the limiting plate 804 retracts into the side wall of the limiting frame 6. Then, after the locking part 7 is locked into the limiting frame 6, the pull on the pulling part 802 is released. Under the elastic force of the return spring 805, the limiting plate 804 gradually returns to its original position, so that the locking rod 806 locks the locking part 7, which facilitates the subsequent replacement and maintenance of the limiting part 9 by the staff and facilitates the use of the tooling fixture by the staff.
