Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, and particularly relates to a vehicle rear longitudinal beam tooling fixture. Background Art

[0002] The vehicle rear longitudinal beam is a very important part of the vehicle structure, which bears the load of the vehicle and the energy absorption function during collision. The rear longitudinal beam is usually located at the rear of the vehicle and, together with the front longitudinal beam, constitutes the skeleton structure of the vehicle. During a collision, the rear longitudinal beam can absorb and disperse the impact force to protect the safety of passengers.

[0003] The material of the rear longitudinal beam is usually high-strength or ultra-high-strength hot-rolled steel plate to ensure that it has sufficient strength to bear the weight of the vehicle and the impact force during collision. There are various cross-sectional shapes of the rear longitudinal beam, such as trough-shaped, box-shaped, I-shaped, Z-shaped, etc., and different cross-sectional shapes are suitable for different vehicle types and design requirements.

[0004] During the vehicle assembly process, it is necessary to install the rear longitudinal beam on the inner side wall of the vehicle frame. Considering that there are various cross-sectional shapes of the rear longitudinal beam, when using a tooling fixture for clamping, it is usually necessary to replace the fixture according to the actual situation to ensure the stability of the clamping state. In addition, it is also necessary to send the rear longitudinal beam to the specified installation position. However, the operation of the traditional vehicle rear longitudinal beam tooling fixture is relatively cumbersome, resulting in low efficiency of manual operation. Therefore, a vehicle rear longitudinal beam tooling fixture is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a vehicle rear longitudinal beam tooling fixture, which has the advantages of good flexibility and high stability, and solves the problems of inconvenient use and low operation efficiency of the traditional vehicle rear longitudinal beam tooling fixture equipment.

[0006] To achieve the above purposes of good flexibility and high stability, the utility model provides the following technical solution: a vehicle rear longitudinal beam tooling fixture, including a base, a driving component arranged on the top of the base, and a clamping component arranged on the side of the driving component.

[0007] Further, the clamping component includes a fixed seat movably connected to the side of the driving component, a connecting seat fixedly installed on the side of the fixed seat, a limit jack arranged on the side of the connecting seat, a positioning notch arranged on the top of the connecting seat, a threaded hole and a limit hole arranged on the side of the fixed seat, a clamping seat movably connected to the side of the fixed seat, a fixed clamp inserted on the top of the clamping seat, and a limit clamp slidably connected to the side of the fixed seat.

[0008] Further, a plurality of moving wheels are arranged at the bottom of the base, and a storage notch for cooperating with the clamping component is arranged on the top side of the base.

[0009] Furthermore, the interior of the limit socket is provided with teeth, and a limit rod is provided inside the limit socket for use therewith. Two rods are provided on the side of the limit clamp and transversely penetrate the fixed seat to the interior of the positioning slot. A toothed slot for use with the limit rod is provided at the bottom of the rod.

[0010] Furthermore, a rotatably connected locking screw and a fixedly installed limiting slide are provided on the side of the clamping seat. The locking screw passes through the threaded hole transversely and is rotatably connected to the threaded hole via a thread, and the limiting slide passes through the limiting hole transversely and is slidably connected to the limiting hole.

[0011] Furthermore, the driving assembly includes a rotating seat rotatably connected to the base, a plurality of support plates fixedly mounted on the top of the rotating seat, a lifting seat slidably connected to the top of the support plate, a hydraulic lifting rod fixedly mounted on the top of the rotating seat, a rotating disk rotatably connected to the inner wall of the lifting seat, a servo motor fixedly mounted on the side of the lifting seat, and a connecting rod fixedly mounted on the side of the rotating disk.

[0012] Furthermore, the side of the connecting rod is provided with a toothed through hole used in conjunction with the limiting socket. The side of one end of the bottom of the connecting rod is arc-shaped and inserted into the open groove at the top of the connecting seat. The limiting socket passes through the toothed through hole horizontally and is slidably connected to the connecting rod.

[0013] Furthermore, the lifting seat is a U-shaped structure and has slots on both sides of the bottom for use with the support plate. The top of the support plate is embedded in the slot and slidably connected to the lifting seat. The bottom of the lifting seat and the top of the hydraulic lifting rod are fixedly installed.

[0014] Furthermore, the output shaft of the servo motor transversely penetrates the side wall of the lifting seat and is fixedly mounted on the side of the rotating disk.

[0015] Compared with the prior art, the utility model provides a vehicle rear longitudinal beam fixture, which has the following beneficial effects:

[0016] 1. The vehicle rear longitudinal beam fixture is configured such that a limit clamp is embedded into the side of a fixing seat so that an insertion rod arranged on the side of the limit clamp horizontally penetrates the fixing seat to the inside of a positioning notch, and then one end of a connecting rod is inserted into the notch at the top of the connecting seat. After the connecting seat is rotated at a certain angle, the limit insertion rod is inserted into the limit insertion hole, passes through the connecting rod and comes out from the other end of the connecting seat. Since the teeth on the outside of the limit insertion rod are respectively engaged with the connecting rod and the connecting seat, and at the same time, the cross bar on the side of the limit clamp is nested in the outside of the limit insertion rod, the connecting rod and the connecting seat form a stable structure.

[0017] 2. For the vehicle rear longitudinal beam tooling fixture, after inserting the fixed clamp adapted to the shape of the rear longitudinal beam into the top of the clamping seat, place the rear longitudinal beam on the top of the clamping seat, and rotate the locking screw. The locking screw rotates inside the fixed seat, thereby driving the clamping seat to approach the fixed seat under the limitation of the limit slide rod and the limit hole. The fixed clamp pushes the rear longitudinal beam to approach the limit clamp on the side of the fixed seat, so as to achieve stable clamping and fixing of the rear longitudinal beam. Push the base to move and send the rear longitudinal beam to the bottom of the vehicle frame. Start the servo motor to drive the rotation of the rotating disk. The rotation of the rotating disk drives the connecting rod to perform a certain degree of angular transformation, so as to send the rear longitudinal beam to the designated installation position at the bottom of the vehicle frame, thus solving the problems of inconvenient use and low stability of the traditional vehicle rear longitudinal beam tooling fixture equipment.

[0024] In this embodiment, a plurality of movable wheels 11 are arranged at the bottom of the base 1, and a storage slot 12 for cooperating with the clamping assembly 3 is opened on the side of the top of the base 1.

[0025] The movable wheels 11 are provided to facilitate transporting the clamped rear longitudinal beam to the bottom of the vehicle frame for installation. The storage slot 12 stores the clamping assembly 3 placed at the bottommost position to avoid impact during storage.

[0026] In this embodiment, the clamping assembly 3 includes a fixed seat 31 movably connected to the side of the driving assembly 2, a connecting seat 32 fixedly installed on the side of the fixed seat 31, a limit jack 33 opened on the side of the connecting seat 32, a positioning slot 34 opened on the top of the connecting seat 32, a threaded hole 35 and a limit hole 36 opened on the side of the fixed seat 31, a clamping seat 37 movably connected to the side of the fixed seat 31, a fixed clamp 38 inserted into the top of the clamping seat 37, and a limit clamp 39 slidably connected to the side of the fixed seat 31.

[0027] The fixed seat 31 and the connecting seat 32 are provided to limit the clamping seat 37, the fixed clamp 38 and the limit clamp 39, so that the rear longitudinal beam can be clamped smoothly.

[0028] In this embodiment, a locking screw 371 rotatably connected and a limit slide bar 372 fixedly installed are arranged on the side of the clamping seat 37. The locking screw 371 horizontally penetrates through the threaded hole 35 and is rotationally connected to the threaded hole 35 through threads. The limit slide bar 372 horizontally penetrates through the limit hole 36 and is slidably connected to the limit hole 36.

[0029] In this embodiment, the driving assembly 2 includes a rotating seat 21 rotatably connected to the base 1, a plurality of support plates 22 fixedly installed on the top of the rotating seat 21, a lifting seat 23 slidably connected to the top of the support plates 22, a hydraulic lifting rod 24 fixedly installed on the top of the rotating seat 21, a rotating disc 25 rotatably connected to the inner side wall of the lifting seat 23, a servo motor 26 fixedly installed on the side of the lifting seat 23, and a connecting rod 27 fixedly installed on the side of the rotating disc 25.

[0030] In this embodiment, the inner part of the limit jack 33 is provided with tooth patterns. A limit plug 331 used in cooperation is arranged inside the limit jack 33. Two plugs are arranged on the side of the limit clamp 39 and horizontally penetrate through the fixed seat 31 to the inside of the positioning slot 34. Tooth pattern slots used in cooperation with the limit plug 331 are opened at the bottom of the plugs.

[0031] In this embodiment, a tooth pattern through hole used in cooperation with the limit jack 33 is opened on the side of the connecting rod 27. One end side at the bottom of the connecting rod 27 is arc-shaped and inserted into the opening slot at the top of the connecting seat 32. The limit plug 331 horizontally penetrates through the tooth pattern through hole and is slidably connected to the connecting rod 27.

[0032] A tooth pattern is provided inside the limit jack 33 to cooperate with the limit insertion rod 331 and the connecting rod 27 for fixation. In this way, the angle of the connecting seat 32 can be adjusted according to actual needs, so that when the connecting rod 27 rotates, the clamping assembly 3 can be accurately sent to the designated position on the vehicle frame.

[0033] In this embodiment, the lifting seat 23 is of a U-shaped structure and slot holes for cooperating with the support plate 22 are provided on both sides of the bottom. The top of the support plate 22 is embedded inside the slot holes and is slidably connected to the lifting seat 23.

[0034] The lifting seat 23 is arranged to lift on the top of the support plate 22, so as to more flexibly send the rear longitudinal beam to the bottom of the vehicle frame.

[0035] In this embodiment, the output shaft of the servo motor 26 horizontally penetrates the side wall of the lifting seat 23 and is fixedly installed on the side surface of the rotating disk 25.

[0036] The working principle of the above embodiment is as follows:

[0037] By inserting the limit clip 39 into the side surface of the fixed seat 31, the insertion rod provided on the side surface of the limit clip 39 horizontally penetrates the fixed seat 31 into the internal positioning notch 34. Then, one end of the connecting rod 27 is inserted into the slot on the top of the connecting seat 32. After rotating the connecting seat 32 by a certain angle, the limit insertion rod 331 is inserted into the limit jack 33, passes through the connecting rod 27 and penetrates out from the other end of the connecting seat 32. Since the tooth patterns on the outer side of the limit insertion rod 331 are respectively meshed with the connecting rod 27 and the connecting seat 32, and at the same time, the cross bar on the side surface of the limit clip 39 is nested on the outer side of the limit insertion rod 331, the connecting rod 27 and the connecting seat 32 form a stable structure.

[0038] In addition, after inserting the fixed clip 38 adapted to the shape of the rear longitudinal beam on the top of the clamping seat 37, the rear longitudinal beam is placed on the top of the clamping seat 37. The locking screw 371 is rotated. The locking screw 371 rotates inside the fixed seat 31, thereby driving the clamping seat 37 to approach the fixed seat 31 under the limitation of the limit slide rod 372 and the limit hole 36. The fixed clip 38 pushes the rear longitudinal beam to approach the limit clip 39 on the side surface of the fixed seat 31, so as to realize stable clamping and fixation of the rear longitudinal beam. The base 1 is pushed to move to send the rear longitudinal beam to the bottom of the vehicle frame. The servo motor 26 is started to drive the rotation of the rotating disk 25. The rotation of the rotating disk 25 drives the connecting rod 27 to perform a certain degree of angular transformation, so as to send the rear longitudinal beam to the designated installation position at the bottom of the vehicle frame, thus solving the problems of inconvenient use and low stability of the traditional vehicle rear longitudinal beam tooling fixture equipment.
