Background
The clamp is a connecting device between the machine tool and the workpiece, and the position precision, the shape precision and the size precision of the machined surface of the workpiece are directly influenced by the quality of the clamp. The process of determining that the workpiece has taken the correct position on the machine tool or in the fixture is often referred to as positioning. After the positioning of the workpiece, the workpiece should be fixed by a certain mechanism or device in order to avoid the positioning from being damaged by the cutting force, gravity, and the like during the machining. The operation of holding the positioning position of the workpiece during the machining process is called clamping, and the process of positioning and clamping the workpiece is called clamping. In the prior art, the clamping components of most of the downward pressing type clamps are symmetrical and synchronously move, and once the positioning parts of the machined parts are not on the same horizontal plane, one side of the downward pressing component is pressed to the surface of the machined part, and the other side of the downward pressing component stops pressing and cannot be fixed, so that the machined part cannot be fastened, the use limitation exists, and the operation is inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anchor clamps structure of CNC processing usefulness to solve the problem of unevenness machined part location.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an anchor clamps structure for CNC processing, includes the operation panel, the inboard symmetrical welding of operation panel has the guide block, the inboard sliding connection of guide block has first rack and second rack, the operation panel is passed to the upper end of first rack and second rack, be connected with the gear between first rack and the second rack.
Preferably, the inside fixed mounting of operation panel has the cylinder, and the upper end of cylinder is fixed and is provided with the installation piece, and the inboard rotation of installation piece installs the gear.
Preferably, the upper ends of the first rack and the second rack are provided with adjusting openings, and the inner sides of the adjusting openings are connected with lower pressing blocks in a sliding mode.
Preferably, the upper ends of the first rack and the second rack are in threaded connection with a positioning bolt, and the lower end of the positioning bolt is abutted with a lower pressing block.
Compared with the prior art, the beneficial effects of the utility model are that: when the machined part is fixed, the first rack and the second rack are driven to move downwards along the guide block through the linkage of the air cylinder, when the lower pressing block at the upper end of the second rack is downwards abutted to the surface of the machined part and the lower pressing block at the upper end of the first rack is not abutted to the machined part, the air cylinder can drive the gear to downwards rotate along the surface of the second rack, the first rack is connected through gear meshing to drive the first rack to continue downwards abut the machined part through the lower pressing block, and therefore the lower pressing positioning of the machined part with unevenness is achieved.
The positions of the lower pressing blocks in the adjusting openings can be adjusted to position workpieces with different sizes in a certain range.
