As shown in fig. 1 and 2, the present utility model provides a gypsum board slitting saw, which comprises a motor 1, a saw blade 2 and a fixing device 3, wherein the motor 1 is used as a power element for providing power for the rest elements, the saw blade 2 is loaded on the motor 1 for cutting gypsum boards, and the fixing device 3 is used for fixedly loading the saw blade 2 on the motor 1, so that the motor 1 can drive the saw blade 2 to rotate, and the saw blade 2 has cutting capability.
Because the division work of gypsum board is mostly indoor going on, easily adopts the electric energy as the direct energy, secondly because the rotational speed of motor 1 is stable, and the running noise is less, and just can be continuous work as long as connecting the power, is applicable to the division work of gypsum board, also can adopt other power supplies through pivot rotation output stable power to replace.
The saw blade 2 is directly fixed with the output shaft 11 of the motor 1 through the fixing device 3, so that the saw blade 2 rotates under the power of the motor 1, the gypsum board can be cut through the friction effect between the edge of the saw blade and the gypsum board, the advantage of direct connection of the saw blade and the motor 1 is realized in that the loss of the power of the motor 1 is reduced due to the reduction of the transmission mechanism in the middle, the energy utilization rate is improved, the middle speed reducer is removed, the rotating speed of the saw blade 2 is faster, the response is more timely and rapid when the motor 1 is started, the incision of the gypsum board is smoother, burrs are less, and the tape sealing is convenient to paste.

Further, the fixing device 3 includes a shaft sleeve 31, a clamping mechanism 32, and a bolt 33, where the shaft sleeve 31 is fixed to the output shaft 11 at the side of the motor 1, so that the output shaft 11 can drive the shaft sleeve 31 to rotate around the axis of the output shaft 11, the clamping mechanism 32 is installed on the shaft sleeve 31, and simultaneously fixes the saw blade 2 on the shaft sleeve 31, and makes the saw blade 2 rotate around the axis of the output shaft 11, and can follow the shaft sleeve 31 to have cutting capability under the driving of the output shaft 11, a threaded hole 111 is formed at the end of the output shaft 11, the bolt 33 is in threaded connection with the threaded hole 111, and a nut 331 at the top of the bolt 33 plays a limiting role on the clamping mechanism 32, so as to fix the saw blade 2 on the shaft sleeve 31.
The shaft sleeve 31 is arranged to realize the detachable fixing of the saw blade 2 to the shaft end of the output shaft 11 of the motor 1, and the rotation of the output shaft 11 needs to be transmitted to the saw blade 2, so the shaft sleeve 31 needs to be fixed to the shaft end of the output shaft 11, and the fixing mode can be interference fit, key connection or welding fixation.
The clamping mechanism 32 is used for fixing the saw blade 2 on the shaft sleeve 31, and fixedly connecting the saw blade 2 with the shaft sleeve 31 in a clamping mode, so that the saw blade 2 can rotate along with the output shaft 11 of the motor 1 along with the shaft sleeve 31, and the bolt 33 at the end part of the output shaft 11 in threaded connection with the output shaft 11 can start the limiting effect on the clamping mechanism 32, so that the saw blade 2 is always limited on the shaft sleeve 31 while being clamped, and the saw blade is prevented from being separated from the shaft sleeve 31 when the output shaft 11 rotates.
Further, the clamping mechanism 32 includes a first clamp 321 and a second clamp 322, the first clamp 321 is fixed with the shaft sleeve 31, and a mounting hole 3221 is formed in the middle of the second clamp 322; the second clamp 322 is sleeved at the end of the shaft sleeve 31, and the inner diameter of the mounting hole 3221 is attached to the outer diameter of the shaft sleeve 31, so that the second clamp 322 can be slidably assembled and disassembled relative to the end of the shaft sleeve 31; the saw blade 2 is disposed between the first clamp 321 and the second clamp 322, and is sleeved on the shaft sleeve 31, and two sides of the saw blade 2 are tightly attached to the second clamp 322 and the second clamp 322.
The first clamp 321 plays a role in clamping and positioning the installation of the saw blade 2, is fixed on the shaft sleeve 31, is integrally sleeved on the outer side of the shaft sleeve 31, can be in interference fit, or can be fixed through a transverse anchor bolt, and can also be directly welded together, so that the first clamp 321 and the shaft sleeve 31 are connected into a whole, the first clamp 321 is fixed in position, when the saw blade 2 is installed, the side part of the saw blade 2 is attached to the side part of the first clamp 321, the position of the saw blade 2 can be determined and limited, and the clamping effect of the first clamp 321 is mainly reflected by the extrusion of the second clamp 322 on the saw blade 2.
The second clamp 322 is detachable, the mounting hole 3221 in the middle of the second clamp can enable the second clamp to slide along the end portion of the shaft sleeve 31, the first clamp 321 can be matched with the first clamp 321 in an inward sliding manner to squeeze the saw blade 2, and the second clamp 322 can also be taken down from the end portion of the shaft sleeve 31 in an outward sliding manner, so that the saw blade 2 can be taken down further, and the saw blade 2 can be replaced.
After the second clamp 322 is installed at the end part of the shaft sleeve 31 and is attached to the side part of the saw blade 2, the extrusion fastening force of the second clamp 322 to the side part of the saw blade 2 is obtained through the bolt 33 at the outer side of the second clamp 322, after the bolt 33 is in threaded connection with the threaded hole 111 at the end part of the output shaft 11, a constant extrusion force facing the saw blade 2 exists on the side part of the second clamp 322 by the nut 331 at the end part of the bolt 33, so that the second clamp 322 can be matched with the fixed first clamp 321 to extrude and fix the saw blade 2, and when the device works, the first clamp 321 and the second clamp 322 rotate together with the shaft sleeve 31 and drive the saw blade 2 to rotate together through static friction force of the side parts of the first clamp and the second clamp and the saw blade 2.
The advantage of driving the saw blade 2 through static friction is that if the external part of the saw blade 2 is subjected to great rotation resistance, the static friction between the saw blade 2 and the first clamp 321 and the second clamp 322 can be converted into dynamic friction, so that the overload protection effect is achieved on the saw blade 2 and the whole device, and the saw blade 2 is prevented from being broken and splashed, so that danger is generated.
Further, a spacer 4 is disposed between the side portion of the second clamp 322 and the nut 331, and the spacer 4 is tightly attached to the side portion of the second clamp 322 and the bottom surface of the nut 331.
The gasket 4 has the function of increasing the static friction force of the side part of the nut 331 of the bolt 33 after being in threaded connection, avoiding loosening, and the gasket 4 has larger area, so that the pressurizing force at the bottom of the nut 331 can be uniformly applied to the side part of the second clamp 322, and the whole system is more stable to fix.
Further, the sides of the first clamp 321 and the second clamp 322, which are attached to the saw blade 2, are provided with anti-slip patterns 323.
The anti-skid pattern 323 can increase the static friction between the first clamp 321 and the second clamp 322 and the saw blade 2, and improve the response speed of the saw blade 2 following the rotation of the output shaft 11 after the motor 1 is started.
Further, the first clamp 321 and the second clamp 322 are both in a boss shape, and the contact surface of the two clamps and the saw blade 2 is a side with larger area; the side parts of the first clamp 321 and the second clamp 322 are hollow, and are provided with a plurality of fixing plates 34 which are uniformly distributed in a ring shape around the rotation center.
The boss-shaped design can further reduce the volumes of the first clamp 321 and the second clamp 322 while not affecting the contact area between the first clamp 321 and the second clamp 322 and the saw blade 2, thereby reducing the mass thereof; the hollow design of the side parts of the first clamp 321 and the second clamp 322 further lightens the mass of the first clamp 321 and the second clamp 322, lightens the load of the output shaft 11, improves the overall stability of the system, and the design of the fixing plate 34 enables the first clamp 321 and the second clamp 322 to lighten the weight of the first clamp and the second clamp and maintain the firmness of the first clamp and the second clamp while lightening the weight of the first clamp and the second clamp.
