Description

Flexible flat coupler structure Technical Field The utility model relates to the technical field of machining of power tool apron, in particular to a flexible flat coupler structure. Background At present, the connection mode of the tool apron product and the tool turret mechanism in the market is rigid connection, and the tool apron is connected through a flat key with a square shape on a connecting column so as to clamp the flat-position coupling sleeve and further through a flat-position coupling block on the flat-position coupling sleeve. The main defects of the existing rigid connection are that the rigid connection has very high requirements on part processing (the precision of parts cannot meet the requirements under many conditions), the rigid connection has large vibration, temperature rise and rapid rising of noise during operation, and the tool apron product is limited to be unstable in the high-speed operation field (12000 revolutions per minute or more), so that the processing performance of the tool apron product is severely restricted. Therefore, a flexible flat coupling structure is needed to address this problem. Disclosure of utility model The utility model aims to provide a flexible flat coupler structure, which enables the flat coupler to be offset in any direction by a small extent so as to adapt to the misalignment condition when being connected with a cutter tower, thereby eliminating the phenomena of vibration, large noise, temperature rise and the like in the high-speed running field (over 12000 revolutions), and greatly improving the processing performance of a cutter seat product. The utility model is realized in the following way: The flexible flat shaft coupling structure comprises a cutter tower body, wherein a connecting mechanism for a cutter seat is arranged on the cutter tower body, the connecting mechanism comprises a flat shaft sleeve, and a flat connecting block is arranged on the flat shaft sleeve; The flat shaft coupling of the cutter tower body is provided with a connecting column matched with the flat shaft coupling sleeve, a plurality of clamping grooves are uniformly formed in the outer wall of the connecting column at intervals, and the clamping grooves are U-shaped grooves. And the clamping grooves are respectively provided with clamping pins. The number of the clamping grooves is 6, the intervals are uniformly formed in the outer wall of the connecting column, and the clamping pins are cylinders. Further, the bayonet lock is bearing steel cylindric lock and polyurethane cylindric lock, bearing steel cylindric lock and polyurethane cylindric lock are three respectively, and bearing steel cylindric lock and polyurethane cylinder interval card are established in the draw-in groove. The three cylindrical pins are replaced by polyurethane rods, so that the flat coupler can be offset in any direction by a small extent to adapt to the misalignment condition when being connected with a cutter tower. Further, an embedded groove matched with the clamping groove and used for clamping the clamping pin is formed in the inner wall of the flat-position coupling sleeve. When the flat position coupling sleeve is sleeved on the connecting column, the bayonet lock on the connecting column is clamped in the embedded groove in the inner wall of the flat position coupling sleeve, so that the flat position coupling block on the flat position coupling sleeve is driven by the tool apron to drive the flat position coupling sleeve to rotate, and the flat position coupling sleeve rotates to drive the connecting column to rotate through the bayonet lock. Further, an elastic pin is arranged through the flat shaft sleeve and the connecting column. The elastic pin can stably connect the flat shaft sleeve with the connecting column in the horizontal direction, so that the situation that the flat shaft sleeve is displaced in the horizontal direction from the connecting column can not occur. The utility model further discloses a working principle of the torque transmission device, which is different from a traditional structure of transmitting torque by connecting two flat keys, and adopts a structure of six cylindrical pins, wherein the cylindrical pins are uniformly distributed on the circumference of a connecting column, the torque transmitted by the structure is larger, the transmission is more stable, and the three cylindrical pins are replaced by polyurethane rods, so that the flat coupler can shift slightly in any direction to adapt to the misalignment condition when being connected with a cutter tower, thereby eliminating the phenomena of vibration, large noise, temperature rise and the like in the high-speed operation field (more than 12000 revolutions), and greatly improving the processing performance of a cutter seat product. Compared with the prior art, the utility model has the beneficial effects that: the flat coupler can be offset in any direction by a small extent to adapt to the
