Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, and in particular to an auxiliary tooling for processing vehicle body anti-collision beams. Background Technology

[0002] A crash beam is a device used to absorb collision energy when a vehicle is involved in a collision. It consists of a main beam, an energy-absorbing box, and a mounting plate that connects to the car. Both the main beam and the energy-absorbing box can effectively absorb collision energy when a vehicle is involved in a low-speed collision, minimizing the damage to the longitudinal beams of the vehicle body from the impact force. This is how it plays its role in protecting the vehicle.

[0003] Currently, during the manufacturing process, the vehicle body anti-collision beam requires the use of positioning auxiliary tooling to position and fix it so that operations such as drilling can be performed.

[0004] When existing positioning auxiliary fixtures are used to position and fix the vehicle body anti-collision beam, at least one side of the anti-collision beam will be completely closed and cannot be processed. This results in a second clamping after the first processing, which is quite troublesome and affects the processing efficiency of the vehicle body anti-collision beam.

[0005] To address this, an auxiliary tooling for machining vehicle body anti-collision beams is proposed. Utility Model Content

[0006] This utility model is an auxiliary tooling for processing vehicle body anti-collision beams, proposed to overcome the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary tooling for processing a vehicle body anti-collision beam, including a base, a vehicle body anti-collision beam blank, and a controller fixedly installed on one side of the base. Two bearing seats are symmetrically fixedly connected to the top of the base. The inner rings of the bearings built into the two bearing seats are fixedly connected to a rotating shaft. A rotating component is fixedly connected between each rotating shaft and the adjacent bearing seat. Each of the two rotating shafts has a mounting base fixedly connected to one adjacent end, and two lower positioning plates are fixedly connected to one adjacent side of the two mounting bases. The blank of the vehicle body anti-collision beam is located above the two lower positioning plates. A pneumatic side positioning assembly is fixedly installed on one side of the outer surface of each of the two lower positioning plates; Both mounting bases are equipped with pneumatic lifting components, and two upper positioning plates are fixedly connected between the movable ends of the two pneumatic lifting components.

[0008] Furthermore, the rotating assembly includes a fixed base, which is fixedly mounted on the base of an adjacent bearing housing. A servo motor is fixedly connected to the top of the fixed base, and a drive gear is fixedly connected to the drive end of the servo motor. A driven gear is meshed with the top of the drive gear, and the driven gear is fixedly connected to an adjacent rotating shaft. The fixed base facilitates the installation of the servo motor, which can drive the rotating shaft to rotate through the cooperation of the drive gear and the driven gear.

[0009] Furthermore, both of the pneumatic side positioning components include a mounting base, which is fixedly installed on one side of the lower positioning plate. A positioning cylinder is fixedly connected to one side of the outer surface of the mounting base, and the movable end of the positioning cylinder passes through the mounting base and is fixedly connected to a positioning circular plate. The mounting base provides support for the positioning cylinder, which facilitates the installation of the positioning cylinder.

[0010] Furthermore, both of the aforementioned pneumatic lifting components include a lifting cylinder, which is fixedly installed on the top of the mounting base. The movable end of the lifting cylinder passes through the mounting base and is fixedly connected to a slide block. The slide block is fixedly connected to the two upper positioning plates, which can synchronously drive the two upper positioning plates to descend or rise.

[0011] Furthermore, each of the two mounting bases has a slide rail fixedly connected to one side of its inner wall, and the slide rail is slidably connected to the slide block. The slide rail has a limiting effect on the slide block, which can ensure the stability of the slide block's movement.

[0012] Furthermore, both lower and upper positioning plates are configured to match the curvature of the vehicle body anti-collision beam blank, so as to perform upper and lower positioning operations on the vehicle body anti-collision beam blank.

[0013] The beneficial effects of this utility model are: In use, this utility model provides an auxiliary tooling for processing vehicle body anti-collision beams. Through the arrangement of bearing seats, rotating shafts, rotating components, mounting seats, pneumatic lifting components, pneumatic side positioning components, upper positioning plates, and lower positioning plates, a hollow auxiliary tooling is formed. While ensuring the positioning of the vehicle body anti-collision beam, it exposes all four processing areas of the anti-collision beam to be processed, and also allows adjustment of the upward-facing processing surface. This avoids secondary clamping of the anti-collision beam and improves the processing efficiency of the anti-collision beam. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3 As shown, an auxiliary tooling for processing a vehicle body anti-collision beam is disclosed, including a base 1, a vehicle body anti-collision beam blank 3, and a controller fixedly installed on one side of the base 1. Two bearing seats 8 are symmetrically fixedly connected to the top of the base 1. The inner rings of the bearings built into the two bearing seats 8 are fixedly connected to rotating shafts 12. A rotating assembly is fixedly connected between each rotating shaft 12 and the adjacent bearing seat 8. The rotating assembly includes a fixed seat 16, which is fixedly installed on the seat of the adjacent bearing seat 8. A servo motor 9 is fixedly connected to the top of the fixed seat 16. A drive gear 15 is fixedly connected to the drive end of the servo motor 9. A driven gear 10 is meshed with the top of the drive gear 15, and the driven gear 10 is fixedly connected to the adjacent rotating shaft 12.

[0019] Two rotating shafts 12 are fixedly connected to one of their adjacent ends with mounting bases 7. Two lower positioning plates 5 are fixedly connected to one of their adjacent sides. The vehicle body anti-collision beam blank 3 is located above the two lower positioning plates 5. The lower positioning plates 5 are fixed to the mounting bases 7 with bolts, which facilitates disassembly and assembly.

[0020] Pneumatic side positioning components are fixedly installed on one side of the outer surface of each of the two lower positioning plates 5. Each pneumatic side positioning component includes a mounting base 13, and the mounting base 13 is fixedly installed on one side of the lower positioning plate 5. A positioning cylinder 2 is fixedly connected to one side of the outer surface of the mounting base 13, and the movable end of the positioning cylinder 2 passes through the mounting base 13 and is fixedly connected to a positioning circular plate 14. A rubber pad is fixedly connected to one side of the positioning circular plate 14 on the side of the vehicle body anti-collision beam blank 3 to avoid hard contact between the positioning circular plate 14 and the vehicle body anti-collision beam blank 3, thus protecting the vehicle body anti-collision beam blank 3.

[0021] Both mounting bases 7 are equipped with pneumatic lifting components. The movable ends of the two pneumatic lifting components are fixedly connected to two upper positioning plates 4. Both pneumatic lifting components include a lifting cylinder 11, which is fixedly installed on the top of the mounting base 7. The movable end of the lifting cylinder 11 passes through the mounting base 7 and is fixedly connected to a slide block 6. The slide block 6 is fixedly connected to the two upper positioning plates 4 and is fixed to the upper positioning plates 4 with bolts, which facilitates disassembly and replacement. A slide rail is fixedly connected to one inner wall of each of the two mounting bases 7, and the slide rail is slidably connected to the slide block 6. The sliding cooperation between the slide rail and the slide block 6 ensures that the two upper positioning plates 4 are raised and lowered smoothly and avoids uneven load.

[0022] Both lower positioning plates 5 and upper positioning plates 4 are matched with the curvature of the vehicle body anti-collision beam blank 3 to ensure uniform force on the contact surface. Rubber pads are fixedly connected to the bottom of the upper positioning plate 4 and the top of the lower positioning plate 5 to avoid hard contact between the positioning plates and the vehicle body anti-collision beam blank 3, thus protecting the vehicle body anti-collision beam blank 3.

[0023] The controller is electrically connected to the positioning cylinder 2, the lifting cylinder 11, and the servo motor 9 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

[0024] Working principle: The vehicle body anti-collision beam blank 3 is placed above the two lower positioning plates 5. Since the lower positioning plates 5 and the upper positioning plates 4 are both matched with the curvature of the vehicle body anti-collision beam blank 3, this provides initial support for the blank. Subsequently, the pneumatic side positioning assembly starts to work. The positioning cylinder 2 fixed on the mounting seat 13 on one side of the lower positioning plate 5 is activated. The moving end of the positioning cylinder 2 pushes the positioning circular plate 14 to extend and press against the vehicle body anti-collision beam blank 3 from the side, realizing lateral positioning. At the same time, the lifting cylinder 11 at the top of the mounting seat 7, as the core component of the pneumatic lifting assembly, drives the slide 6 to descend, causing the upper positioning plate 4 to move downward until the upper positioning plate 4 is tightly attached to the upper surface of the vehicle body anti-collision beam blank 3. Together with the lower positioning plate 5 and the lateral positioning circular plate 14, the vehicle body anti-collision beam blank 3 is firmly fixed from three directions, ensuring that the blank will not be displaced during processing.

[0025] If the angle of the vehicle body anti-collision beam blank 3 needs to be adjusted during processing, the servo motor 9 is started by the controller. The drive end of the servo motor 9 drives the drive gear 15 to rotate. Since the drive gear 15 is meshed with the driven gear 10 and the driven gear 10 is fixedly connected to the rotating shaft 12, the rotation of the drive gear 15 will drive the driven gear 10, which in turn drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 is transmitted to the lower positioning plate 5, the pneumatic side positioning assembly, the pneumatic lifting assembly, and the upper positioning plate 4 through the mounting base 7, so that the vehicle body anti-collision beam blank 3 fixed therein rotates accordingly to achieve the required processing angle.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
