Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary frame processing, in particular to a clamping device used for auxiliary frame processing. Background Art

[0002] The subframe can be regarded as the skeleton of the front and rear axles. It is an integral part of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axles and suspension are connected to the "main frame" through it. It is customarily called the "subframe".

[0003] As disclosed in Chinese Patent Publication No. (CN218194774U), a clamping device for sub-frame processing relates to the technical field of sub-frame processing, including a base, a processing table is fixedly connected to the top of the base through a support frame, a plurality of strip grooves are opened on the top of the processing table, and an electric slide is fixedly connected to the bottom of the inner surface of the strip groove. The clamping device for sub-frame processing has a plurality of strip grooves opened on the top of the processing table, an electric slide is fixedly connected to the bottom of the inner surface of the strip groove, a connecting plate is fixedly connected to the top of the movable block of the electric slide, and a lifting mechanism is provided on the top of the connecting plate, a clamping mechanism is provided on the top of the lifting mechanism, the electric slide drives the clamping mechanism to move horizontally to adapt to the shape of the sub-frame, a double-headed screw of the clamping mechanism is arranged, and the rotation of the servo motor drives the two clamping plates to approach each other to clamp and fix the inner and outer surfaces of the sub-frame at the same time, thereby improving the clamping stability.

[0004] However, the above patent still has the problem of poor adjustment and clamping effect for sub-frame processing. For example, in the above patent, the motor is rotated to drive two clamping plates to approach each other to clamp and fix the inner surface and outer surface of the sub-frame at the same time. However, in this method, the clamping plates are used to contact and clamp the surface of the sub-frame, and the sub-frame is generally stamped and has an irregular surface. The clamping plates in the above patent are hard in texture. When in contact with the sub-frame, not only is the contact surface small, but the clamping is unstable. It is also easy to damage the surface of the sub-frame during clamping and squeezing, which affects subsequent processing. Utility Model Content

[0030] The working principle of the above embodiment is:

[0031] (1) When the sub-frame is processed and clamped for adjustment and clamping, the mounting base 1 can be installed and used through the mounting bracket and the supporting processing equipment for the sub-frame processing. The pneumatic push rod 21 serves as the power source of the adjustment mechanism 2. It is extended and retracted by receiving compressed air to provide power. The push plate 22 is fixed on the output shaft of the pneumatic push rod 21 and moves synchronously with the push rod. The adjustment plate 23 slides in the adjustment groove 24 on the push plate 22 to adjust the left and right positions to adapt to sub-frames of different widths. After the adjustment plate 23 is in place, it is fixed by the locking screw hole and the locking bolt 27 to prevent displacement during the processing. The guide groove 25 and the slider 26 cooperate to ensure that the push plate 22 maintains a stable and straight trajectory during the movement. The locking bolt 27 slides in the slide groove 28 on the push plate 22, allowing the position of the adjustment plate 23 to be fine-tuned within a certain range.

[0032] (2) When the sub-frame is used for clamping processing, the clamping airbag 32 is expanded and contracted by the compressed air provided by the air pump 33, so as to realize flexible wrapping and clamping of the sub-frame. The fixing frame 31 is fixed to the adjustment plate 23 to provide stable support for the clamping airbag 32. The air pump 33 supplies air to the elastic air tube 35 through the three-way pipe 34, and the elastic air tube 35 transmits the compressed air to the clamping airbag 32. The controller controls the start and stop of the air pump 33 and adjusts the air pressure of the clamping airbag 32, so as to control the clamping force. When the sub-frame needs to be clamped, the controller starts the air pump 33, and the airbag expands to clamp the sub-frame; after the processing is completed, the controller stops the air pump 33, and the airbag contracts to release the sub-frame. Due to the flexible characteristics of the clamping airbag 32, the clamping mechanism 3 can adapt to sub-frames of different shapes and sizes and provide uniform clamping force.
