Description

Technical Field

[0001] This utility model relates to the field of loudspeaker processing technology, and in particular to a clamping device for processing loudspeaker housings. Background Technology

[0002] A loudspeaker, short for loudspeaker unit, is an electroacoustic transducer commonly found in the electroacoustic field. While a relatively weak but crucial component in an electroacoustic system, loudspeakers come in a wide variety of types and prices. Audio energy is transmitted through electromagnetic, piezoelectric, or electrostatic effects, causing the cone or diaphragm to vibrate and create sound. During loudspeaker manufacturing, the housing often needs to be fixed in place. An existing fixture (CN214481272U) for manufacturing loudspeaker housings uses a feed motor to drive a feed screw, clamping the workpiece between a first and second fixed seat. However, because only the first fixed seat is movable, centering and clamping cannot be achieved, leading to clamping position deviation and compromising machining accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a clamping device for processing speaker housings in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A clamping device for processing speaker housings includes a mounting base, a support frame fixed on the mounting base, and an arc-shaped guide rail mounted on the support frame. The support frame has a rotating mechanism, which includes a turntable. A guide groove is fixed on the lower surface of the turntable, and a rotating shaft is connected to the lower surface of the turntable. A power component is mounted on one end of the rotating shaft. A fixed shaft is provided on the turntable, and a clamping plate is provided on the upper surface of the fixed shaft. A sliding groove is provided through the clamping plate, and a clamping mechanism is provided on the clamping plate. The clamping mechanism includes a connecting plate, with L-shaped connecting rods opposite each other on the connecting plate. An I-shaped slider is provided at one end of the L-shaped connecting rod, and an arc-shaped clamping block is fixed on the I-shaped slider. A rubber pad is provided on one side of the arc-shaped clamping block, and a cylinder is provided below the I-shaped slider.

[0006] Further configuration: The flow guide groove corresponds to the arc-shaped guide rail, the flow guide groove is slidably connected to the arc-shaped guide rail, the turntable is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the support frame.

[0007] Further configuration: The fixture plate is fixed on the fixed shaft, and four sets of sliding grooves are provided at intervals, with the I-shaped slider corresponding to the sliding groove.

[0008] Further configuration: The connecting plate is rotatably connected to the fixed shaft, the L-shaped connecting rod is rotatably connected to the connecting plate, the I-shaped slider is rotatably connected to the L-shaped connecting rod, and the I-shaped slider is slidably connected in the sliding groove.

[0009] Further configuration: The cylinder is fixedly connected between two sets of I-shaped sliders. The two sets of cylinders are arranged opposite each other and located on both sides of the fixed shaft. The rubber pad is bonded to the outer surface of one side of the arc-shaped clamping block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By setting up a clamping mechanism and a rotating mechanism, the cylinder of the clamping mechanism drives two sets of I-shaped sliders to move towards the center position. Then, the I-shaped sliders drive the connecting plate to rotate through the L-shaped connecting rod, thereby causing the other two sets of I-shaped sliders to move towards the center position. Finally, the arc-shaped clamping block clamps the workpiece, ensuring that the clamping position is always in the center position, avoiding the problem of inaccurate processing position due to clamping position deviation, and improving the overall processing accuracy. The power component of the rotating mechanism drives the rotating shaft to rotate the turntable, thereby driving the fixture disk to rotate, which can achieve 360-degree rotation, realizing processing at different positions without the need to re-clamp the workpiece.
