Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The present embodiment provides a bench cutter 100 for cutting a work piece such as stone, wood or metal. As shown in fig. 1, the table type cutting machine 100 includes a table assembly 11, a frame 12, a cutting assembly 13, and a support leg assembly 14 for supporting the table assembly 11. Wherein, the workbench component 11 is arranged on the supporting leg component 14 through the frame 12, an accommodating space 121 is further formed between the workbench component 11 and the frame 12, and the cutting component 13 is arranged in the accommodating space 121. As an alternative embodiment, as shown in fig. 2, the table assembly 11, the frame 12 and the cutting assembly 13 may be connected as a whole and can be fixed on the table for cutting.

As shown in fig. 2 to 3, the cutting assembly 13 is integrally fixed to the table assembly 11 and can be rotated relative to the table to adjust the cutting angle. A guide groove 111 for guiding the workpiece to be cut in a straight direction is formed or coupled to the table assembly 11. The cutting assembly 13, after being mounted to the table assembly 11, may have a parallelism problem during use, assembly and transportation, i.e., the cutting axis of the cutting assembly 13 is not parallel to the guide groove 111. In some alternative embodiments, the cutting assembly 13 is mounted to the table assembly 11 by an adjustment device 15, and the adjustment device 15 is capable of adjusting the parallelism of the cutting assembly 13 relative to the guide slot 111. Specifically, when it is desired to adjust the parallelism of the cutting assembly 13 relative to the guide slot 111, the cutting assembly 13 can be released from the table assembly 11 by adjusting the fastener of the adjusting device 15, and then the parallelism of the cutting assembly 13 relative to the guide slot 111 can be adjusted by adjusting the adjusting member 171 of the adjusting device 15. However, in the process of releasing the cutting assembly 13 from the table assembly 11, since the cutting assembly 13 has a heavy weight, it may rapidly fall down under the action of gravity, and the falling distance and angle thereof are not controllable, thereby increasing the complexity of adjusting the parallelism of the cutting assembly 13 with respect to the guide groove 111 of the table assembly 11.

As shown in fig. 4, in order to reduce the dropping distance and the rotating angle of the cutting assembly 13 when adjusting the parallelism so that it stays in a predetermined position, a supporting member 16 for supporting the cutting assembly 13 to drop to the predetermined position is further provided in this embodiment. Specifically, the support member 16 is coupled to the table assembly 11 by a coupling member in a first linear direction perpendicular to the table assembly 11. The adjusting device 15 is disposed between the supporting member 16 and the table assembly 11, and can be supported by the supporting member 16 when released, and can be supported at a predetermined position, thereby preventing an excessive falling distance and a large deflection angle of the cutting assembly 13, so that a user can easily adjust the parallelism of the cutting assembly 13 when one cutting assembly 13 is released and in a free state.

As shown in fig. 5, in particular, the supporting member 16 is a supporting plate having a certain strength, and the supporting member 16 has a supporting surface 161 capable of supporting the cutting assembly 13 at a predetermined position. The support 16 is formed with a first coupling hole (not shown) through which the coupling member passes. It will be appreciated that the table assembly 11 is provided at a predetermined position with a second coupling hole (not shown) coupled with the first coupling hole of the support member 16, and the support member 16 is fixedly coupled to the table assembly 11 by a coupling member and can be adjusted in relative position with respect to the table assembly 11 according to the size of the adjusting device 15. The support 16 has a first position and a second position relative to the table assembly 11, and the support 16 is positioned at the first position a greater distance from the table assembly 11 than the support 16 is positioned at the second position. That is, when the adjusting device 15 itself has a large volume, the distance between the supporting member 16 and the table assembly 11 can be adjusted to be large, and at this time, the supporting member 16 is located at the first position relative to the table assembly 11, which can adapt to the moving range of the adjusting device 15, and it is avoided that the adjusting device 15 is fixed by the supporting member 16 and cannot be adjusted to the moving state, so that the parallelism of the cutting assembly 13 cannot be adjusted. When the volume of the adjusting device 15 is small, the distance between the supporting piece 16 and the workbench assembly 11 can be reduced, the supporting piece 16 is located at the second position relative to the workbench assembly 11, the moving range of the adjusting device 15 can be reduced, and the phenomenon that the adjusting device 15 freely falls in a large range when being released is avoided, so that the falling distance and the deflection angle of the cutting assembly 13 are avoided being too large, and the convenience in adjusting the parallelism of the cutting assembly 13 can be improved.

In fact, the supporting member 16 is further formed with a limiting groove 162, and the adjusting device 15 is formed with or connected with a guide 151 engaged with the limiting groove 162. When the adjusting device 15 is disposed between the supporting member 16 and the worktable assembly 11, the guide 151 is located in the limiting groove 162, so that when the cutting assembly 13 is released by the adjusting device 15, the cutting assembly 13 can move in a predetermined space, thereby preventing the cutting assembly 13 from generating a large offset under the action of an external force. In addition, the adjusting device 15 is further provided with a sliding piece 152 for adjusting the parallelism, and the sliding piece 152 is arranged in a containing cavity formed in the adjusting device 15, so that when the parallelism of the cutting assembly 13 is adjusted, the sliding friction of the adjusting device 15 relative to the supporting piece 16 is converted into rolling friction, the friction force between the adjusting device 15 and the supporting piece 16 is reduced, and the convenience for a user to adjust the parallelism of the cutting assembly 13 is increased. Specifically, the sliding member 152 may be a steel ball disposed in the accommodating cavity, or may be other devices capable of reducing friction.

As shown in fig. 6, the table type cutting machine 100 can also cut the workpiece at different angles during the process of cutting the workpiece, so as to adapt to different requirements of actual working conditions. In some alternative embodiments, the adjusting device 15 further includes a first guide rail (not shown) for rotating the cutting assembly 13, and the first guide rail is disposed at the connection position of the adjusting device 15 and the cutting assembly 13. The cutting assembly 13 is slidable within the confines of the first guide track and can be fixed at a predetermined angle to achieve different angle cuts. The frame 12 is formed with a second guide rail 122 for the cutting assembly 13 to rotate, the cutting assembly 13 is connected to or formed with an operating assembly 131 for operation, and a user can adjust the angle of the cutting assembly 13 through the operating assembly 131. Specifically, the operating assembly 131 passes through the second rail 122 and is slidable within the second rail 122. In a first plane perpendicular to the table plane and passing through the second guide rail 122, the cutting assembly 13 is rotated through an angle greater than or equal to 0 ° and less than or equal to 45 ° with respect to the first plane. For some workpieces needing large-angle or small-angle cutting, the existing adjusting angle cannot meet the requirement.

As shown in fig. 6 to 9, in order to increase the rotation angle of the cutting assembly 13, the present embodiment provides longer first and second rails 122. Specifically, the first guide rail and the second guide rail 122 are both arc-shaped, and the first guide rail and the second guide rail 122 have the same center of circle. More specifically, the first and second rails 122 are each provided in two so that the cutting assembly 13 can be effectively supported. In one embodiment of the present invention, an adjusting assembly 17 is further provided to allow the cutting assembly 13 to rotate within the guide rail to a greater extent.

Specifically, the frame 12 is further formed with a third rail 123 parallel to the second rail 122. It should be explained here that the second guide rail 122 and the third guide rail 123 have the same center, and in any direction of a straight line passing through the center and simultaneously passing through the second guide rail 122 and the third guide rail 123, the straight line intersects the second guide rail 122 and has at least one intersection point, and there is a first tangent line passing through the intersection point; the straight line intersects the third guide rail 123 and has at least one intersection point through which a second tangent line passes, the first tangent line and the second tangent line being always parallel. The adjusting assembly 17 passes through the third guide rail 123 and is fixedly connected with the cutting assembly 13. During the operation of the operating assembly 131 to adjust the angle of the cutting assembly 13, the adjusting assembly 17 moves in synchronization with the operating assembly 131. The adjustment assembly 17 includes an unlocked position enabling rotation of the cutting assembly 13 and a locked position limiting rotation of the cutting assembly 13; when the adjustment assembly 17 is in the unlocked position, the cutting assembly 13 can rotate freely along the first guide rail when the operating assembly 131 is being operated; when the adjustment assembly 17 is in the locked position, the cutting assembly 13 is limited to a predetermined range of rotation along the first guide when the operating assembly 131 is operated.

As shown in fig. 8 to 9, the adjusting assembly 17 includes an adjusting member 171, a first elastic member 172, and a retaining cap 173. The cutting assembly 13 is formed with a receiving groove 132 for receiving the regulating member 171 and the first elastic member 172. The receiving groove 132 is substantially cylindrical, and the first elastic member 172 may be a coil spring, which is sleeved on the adjusting member 171. The first elastic member 172 has one end passing through the third rail 123 and the other end inserted into the receiving groove 132. More specifically, the adjusting member 171 is also cylindrical in shape and includes a first end 171a and a second end 171b, which have a first stopping portion 171c and a second stopping portion 171d protruding from the circumference of the adjusting member 171. The first stopper 171c and the second stopper 171d are disposed between the first end 171a and the second end 171 b. The diameter of the first stopping portion 171c is larger than the width of the third guiding rail 123, and the diameter of the second stopping portion 171d is larger than the diameter of the first elastic member 172. When the first elastic element 172 is sleeved on the adjusting element 171 and mounted in the receiving groove 132, one end of the first elastic element 172 abuts against the inside of the receiving groove 132, and the other end abuts against the second stopping portion 171d, at this time, the adjusting element 171 is abutted against the frame 12 through the first elastic element 172, that is, the first stopping element is tightly attached to the frame 12 and cannot pass through the third guide rail 123. The first end 171a of the adjuster 171 is fixed by the detachment prevention cap 173, preventing the first end 171a of the adjuster 171 from being detached from the frame 12 through the third guide rail 123.

The third guide rail 123 is further provided with a limiting assembly 18 for adjusting the upper limit and the lower limit of the rotation angle of the cutting assembly 13. It should be noted that the lower and upper rotation angle limits described herein are upper and lower limits on the magnitude of the positive clockwise rotation and negative counterclockwise rotation of the cutting assembly 13. The limiting component 18 includes a fastening member 181 and a limiting member 182, a mounting hole for mounting the limiting component 18 is further formed on the frame 12, the limiting member 182 is mounted to the mounting hole through the fastening member 181 and can cover at least part of the mounting hole, that is, the limiting member 182 is mounted on the inner side of the frame 12. In fact, the mounting hole for mounting the limiting assembly 18 is oval, and extends along the extending direction of the third guide rail 123, and the limiting member 182 can adjust the relative distance with the third guide rail 123 through the fastening member 181. The spacing assembly 18 has a first position distal from the third rail 123 and a second position proximal to the third rail 123. Wherein when the position limiting assembly 18 is in the first position, the cutting assembly 13 is free to rotate between the upper limit and the lower limit of the rotation angle without being limited by the adjusting member 171. When the limiting assembly 18 is in the second position, the cutting assembly 13 is limited by the adjusting member 171, and at this time, during the synchronous rotation of the adjusting member 171 with the cutting assembly 13, the limiting member 182 has a stopping effect on the first stopping portion 171c on the adjusting member 171, so as to limit the rotation range of the cutting assembly 13. At this time, the first stopping portion 171c of the adjusting member 171 may be misaligned with the limiting member 182 by pressing the adjusting member 171, so that the limiting member 182 no longer limits the adjusting member 171, thereby increasing the upper limit and the lower limit of the rotation angle of the cutting assembly 13. As one implementation, the limiting component 18 realizes the adjustment of the upper limit and the lower limit of the rotation angle of the cutting component 13, and the adjusting component 17 realizes the adjustment of whether the cutting component 13 can enter the upper limit and the lower limit of the rotation angle.

As shown in fig. 10 to 14, in the second embodiment of the present invention, the adjustment assembly 27 is provided at a position close to the second guide rail. The adjusting assembly 27 includes an eccentric block 271 and an operating member 272 for operating the eccentric block 271, and the frame has a through hole (not shown) through which the operating member 272 is connected to the eccentric block 271 and can adjust the relative position of the eccentric block 271. In fact, the cutting assembly 23 also comprises a projection 231 which cooperates with the eccentric mass 271, the eccentric mass 271 having a first position and a second position with respect to the projection 231. When the eccentric block 271 is in the first position, the protrusion 231 is in contact with the eccentric block 271 and cannot ride over the eccentric block 271, and the cutting assembly 23 is limited to the original rotation range. When the eccentric block 271 is at the second position, the protruding portion 231 is not in contact with the eccentric block 271, and at this time, the eccentric block 271 can allow the protruding portion 231 to pass through, and the upper limit and the lower limit of the rotation angle of the cutting assembly 23 are both increased. The protruding portion 231 is further provided with an adjusting block 232, the adjusting block 232 can adjust the relative position between the adjusting block and the eccentric block 271, and the problem that the protruding portion 231 and the eccentric block 271 cannot be matched for use due to errors generated in the manufacturing, assembling and transporting processes is avoided.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
