Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a universal eccentric adjustable clamp for deep hole drilling of gasoline rail bodies. Background Technology

[0002] In the field of deep hole drilling for gasoline rail bodies, the adjustment accuracy and clamping stability of the fixture directly affect the machining quality. Traditional fixtures mostly adopt fixed clamping structures, which have significant technical defects: First, rigid clamping easily leads to scratches or deformation on the surface of the deep hole drill, especially causing serious damage to high-precision workpieces; second, adjusting the clamping distance relies on manually tightening bolts, which is cumbersome and makes it difficult to ensure symmetry, affecting machining coaxiality; third, the lack of adaptive floating clamping design makes it unable to adapt to different diameters or eccentric workpieces, requiring repeated calibration during model changes, resulting in low efficiency. In existing technologies, although some adjusting fixtures use screw-driven sliders, they are mostly independently adjusted on one side, with poor synchronization, easily causing uneven distribution of clamping force, leading to machining vibration or workpiece displacement. In addition, traditional support mechanisms are mostly fixed V-blocks with low coefficients of friction on the contact surface, which are prone to slippage during high-speed machining, further reducing machining stability.

[0003] For the diverse processing needs of deep hole drilling of gasoline rail bodies, existing problems are more prominent: eccentric workpieces are difficult to position accurately due to the limited adjustment range of the clamp; the clamping surface lacks anti-slip design, making the workpiece prone to displacement during processing; and maintenance requires complete disassembly of the clamp, resulting in long downtime. There is an urgent need for a clamp that integrates symmetrical adjustment, flexible clamping, and anti-slip support to overcome the technical bottlenecks of low precision, poor adaptability, and cumbersome operation of traditional devices.

[0005] The technical solution adopted in the embodiments of this application is as follows:

[0006] A universal eccentric adjustable clamp for gasoline rail deep hole drilling includes a base plate, a support mechanism for supporting the deep hole drill, and clamping assemblies for clamping both ends of the deep hole drill.

The support member is located on the top of each set of sliders. The drive device and the two sets of bearing seats are mounted on the top of the base plate.

[0007] A further technical solution is as follows: the support member includes a support roller for supporting the deep hole drill and a support frame disposed on the slider; the support roller is rotatably connected to the support frame; and the surface of the support roller is provided with a number of anti-slip pads arranged in a circular array.

[0008] A further technical solution is as follows: the clamping assembly includes a support base mounted on the top of the base plate, a floating chuck mechanism for clamping one end of the deep hole drill, and a rotating spindle for driving the floating chuck mechanism to rotate; the rotating spindle is mounted on the support base; and the floating chuck mechanism is disposed on the output end of the rotating spindle.
