Description

Technical Field

[0001] The utility model relates to the technical field of frame pressing structures, in particular to a bidirectional pressing structure for frame processing. Background Art

[0002] In the modern automobile manufacturing industry, frame processing is a key link, especially for electric vehicle frames, which have complex structures and extremely high precision requirements. Traditional frame clamping structures often have problems such as low efficiency, complex operation, and uneven clamping. For example, clamping each frame longitudinal beam individually is not only time-consuming and labor-intensive, but also difficult to ensure the consistency and stability of the clamping force. In addition, vibration and instability during the clamping process may also affect the machining accuracy and quality of the frame. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a bidirectional clamping structure for frame processing, which is used to solve the problems of low efficiency and uneven clamping of the frame clamping structure in the prior art.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A bidirectional clamping structure for frame processing includes a machine base, which is arranged in the middle of the frame and is used to install a driving device; a supporting device, which includes two and is symmetrically arranged on both sides of the machine base; a clamping device, which is connected between the driving device and the supporting device and clamps the frame placed on the supporting device; and a guide device, which is arranged between the machine base and the clamping device and provides guidance for the operation of the driving device.

[0006] To implement the above technical solution, the driving device is installed on the machine base and is located at the center of the two longitudinal beams of the two electric vehicle frames. The two supporting devices are symmetrically arranged on both sides of the machine base to support the two longitudinal beams of the electric vehicle frames. The operation of the driving device is guided by the guide device to ensure the stability and accuracy of its movement. The two clamping devices simultaneously clamp the frames placed on the supporting devices. Through the design of the bidirectional clamping structure, only one driving device is needed to clamp the two longitudinal beams at the same time, which improves the efficiency of the clamping operation and ensures the stability and safety of the frame.

[0007] The clamping force is evenly distributed to avoid deformation of the electric vehicle frame and improve the stability and safety of the electric vehicle frame.

[0008] In one embodiment of the present invention, the guide device includes a slide rail vertically arranged on the machine base and a slider slidably arranged on the slide rail.

[0009] By implementing the above technical solution, the precise matching of the slide rail and the slider improves the accuracy during the frame clamping process, enhances the stability of the clamping device, and reduces vibration during the clamping process.

[0010] In one embodiment of the utility model, the clamping device includes a slide plate arranged on the slider, waist-shaped grooves symmetrically opened on the left and right sides of the slide plate, a connecting rod installed in the waist-shaped groove through a pin shaft, and a clamping arm hinged at the other end of the connecting rod; the output shaft of the driving device is connected to the slide plate and drives the slide plate to move along the slide rail.

[0011] To implement the above technical solution, the output shaft of the driving device is connected to the skateboard, and the power of the driving device is used to push the skateboard to move along the slide rail. Waist-shaped grooves are symmetrically opened on the left and right sides of the skateboard. These waist-shaped grooves are used to accommodate connecting rods, allowing the connecting rods to move left and right in the waist-shaped grooves. The clamping arm is hinged at the other end of the connecting rod to form a lever structure for applying a clamping force to the frame longitudinal beam. When the skateboard moves along the slide rail, the power is transmitted to the clamping arm through the connecting rod to achieve simultaneous clamping of the frames on both sides.

[0012] In one embodiment of the utility model, the supporting device includes a supporting seat, and a mounting platform and a protruding block are provided at the upper end of the supporting seat; a connecting block is hinged on the mounting platform, and the connecting block is provided with the clamping arm, and the clamping arm, the mounting platform and the protruding block enclose a cavity for placing the frame.

[0013] To implement the above technical solution, the supporting device is composed of a supporting seat, and a mounting platform and a protruding block are designed on the upper end of the supporting seat for cooperating with the clamping arm. A connecting block is hinged on the mounting platform, and the connecting block serves as the mounting point of the clamping arm, allowing the clamping arm to swing. The frame is placed in a cavity formed by the clamping arm, the mounting platform and the protruding block, ensuring the stability of the frame during processing.

[0014] In an embodiment of the present invention, a pressing block is provided on the pressing arm, the mounting platform and the protruding block.

[0015] To implement the above technical solution, the clamping block is used to directly contact the frame to achieve the clamping function. The setting of the clamping block ensures that the clamping force can be evenly distributed on the frame to avoid deformation of the frame caused by excessive local pressure. The clamping block can adjust its position or replace materials of different hardness as needed to meet the requirements of different clamping forces.

[0016] As described above, the bidirectional clamping structure for frame processing of the utility model has the following beneficial effects: the bidirectional clamping structure of the present invention simultaneously clamps two frame longitudinal beams through a driving device, which significantly improves the efficiency of the clamping operation; the design of the clamping block ensures the uniform distribution of the clamping force on the frame, avoiding deformation of the frame caused by excessive local pressure; the design of the supporting device and the clamping device ensures the stability and safety of the frame during the processing; the slide rail and the slider of the guide device are precisely matched, which improves the accuracy of the clamping process and reduces the vibration during the clamping process, thereby improving the accuracy of the frame processing; the design of the slide plate, connecting rod and clamping arm reduces wear points and improves the durability of the entire clamping structure.
