Description

Technical Field

[0001] The utility model relates to the technical field of round clamps, in particular to a round clamp with a three-side clamping function. Background Art

[0002] Circular clamps are mainly used to clamp circular workpieces, such as shafts, gears and discs, for processing, assembly, testing and other operations. They have the characteristics of large clamping force, no damage to the clamping surface, high precision and good stability. They are widely used in machinery, automobiles, electronics, light industry and other industries.

[0003] However, most circular clamps mainly clamp shafts, gears and discs through two semicircles, which can easily cause deformation of the workpiece during the clamping process. At the same time, the stability of clamping irregular circular workpieces through two semicircles is poor, making the circular clamps inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to provide a circular clamp with a three-sided clamping function to solve the problem that the circular clamp proposed in the background art has a poor clamping effect when in use.

[0006] Preferably, the inner thread of the locking nut is connected to a first screw rod, and the bottom end of the first screw rod is connected to a suction cup body.

[0007] Preferably, a rotating shaft is rotatably connected between the adjusting claw and the mounting plate, and a ratchet is welded to one side of the rotating shaft.

[0008] Preferably, a clamping block rotatably connected via a rotating shaft is provided at one end of the mounting plate close to the ratchet, and a limiting block is provided at one end of the ratchet away from the clamping block.

[0009] Preferably, an adjustment seat is welded to one side of the limit block, and a limiting spring is welded to the inside of the adjustment seat and the mounting plate.

[0010] Preferably, the top of the limit block is provided with evenly distributed limit claws, and one side of the limit claw is welded to the limit block.

[0011] Preferably, an adjustment block is provided at the top of the adjustment seat, a moving rod is welded to one end of the adjustment block away from the adjustment seat, a second screw is connected to the internal thread of the moving rod, and a hand wheel is connected to the top of the second screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the circular clamp with a three-sided clamping function, by installing the suction cup body at the bottom of the adjusting claw, and the three suction cup bodies can be used to absorb the workpiece more stably, thereby preventing the circular clamp from falling off when clamping the workpiece, and the position of the suction cup body can be adjusted by locking the locking nut with the adjusting slots at different positions, so that workpieces of different sizes can be grasped, and the hand wheel is turned and then the angle of the adjusting claw is turned, so that the adjusting claw can be quickly adjusted to a suitable position to grasp the workpiece, and the hand wheel is turned again so that the adjusting claw with the adjusted angle can be quickly fixed.

[0013] 1. The circular clamp with three-sided clamping function is easy to fall off when clamping when in use. By installing the first screw inside the locking nut and locking the locking nut with the adjusting groove, the suction cup body can be quickly installed at the bottom of the adjusting claw. At the same time, there are three adjusting claws on one side of the mounting plate, so that the three suction cup bodies can be used to absorb the workpiece more stably, and the circular clamp can be prevented from falling off when clamping the workpiece. The locking nut can be locked with the adjusting grooves at different positions, so that the position of the suction cup body can be adjusted, so that workpieces of different sizes can be grasped, making the circular clamp more convenient to use.

[0014] 2. When the circular clamp with three-sided clamping function is in use, it is usually not easy to clamp irregular workpieces. By rotating the hand wheel, the hand wheel can move the moving rod through the connected second screw rod when rotating, so that the moving rod can move the adjustment block when moving, so that the adjustment block can be separated from the adjustment seat when moving, so that the limiting spring set on one side of the adjustment seat can be reset, and the adjustment seat and the limit block are displaced, so that the limit block can separate the limit claw and the limit block from the ratchet after displacement. , by rotating the angle of the adjusting claw, the adjusting claw can be quickly adjusted to a suitable position to grab the workpiece, so that after adjusting to a suitable position, the hand wheel is rotated, so that the hand wheel can move the adjusting block through the connected second screw when rotating, so that the adjusting block can squeeze the adjusting seat when moving, and then the adjusting seat can move the limit block, and at the same time squeeze the limit spring, so that the limit claw and the limit block set at one end of the limit block can limit the ratchet, so that the adjusting claw with the adjusted angle can be quickly fixed.
