Description

Circular saw bit laser processing equipment

Technical Field

The utility model relates to the field of circular saw bit processing, in particular to circular saw bit laser processing equipment.

Background

As is well known, circular saws are widely used in various cutting processes, such as wood processing. In order to prolong the service life of the circular saw, it is a common practice to weld a cutting head made of a superhard material (such as, but not limited to, diamond) to a pre-machined tooth at a circular saw base, and since the cutting head is made of the superhard material and the circular saw base is made of a material with good flexibility and hardness lower than that of the cutting head, such a combination effectively increases the service life of the circular saw.

After the tool bit is welded to the circular saw base, the final product can be obtained only by cutting the rear tool face and the side tool face of the tool bit.

More specifically, the following:

as shown in fig. 1 and 4, the pivotal seat 70a is pivotally swung within a range of plus or minus 95 degrees under the driving of the pivotal swing driving mechanism 70b, that is, the pivotal swing seat 70a can pivotally swing about the upper and lower pivotal swing center line L1 within an angle range of 0 to 190 degrees, for example, in fig. 4, the pivotal seat 70a is set to be at an initial position of 0 degree, at a first limit position when the pivotal seat 70a rotates clockwise to 95 degrees about the upper and lower pivotal swing center line L1, and at a second limit position when the pivotal seat 70a rotates counterclockwise from the initial position to 95 degrees about the upper and lower pivotal swing center line L1, so that the included angle between the first limit position and the second limit position is 190 degrees.

As shown in fig. 1 and 7, the picosecond laser 50 is driven by the angle adjustment mechanism 40 to pivot around the first pivot center line L2 within a range of 0 to 27 degrees, and preferably, the first pivot center line L2 is horizontally arranged along the left-right direction of the rack 10, so that the width of the rack 10 can be reduced, but not limited thereto.

For example, the gear-shifting device 63 is mainly composed of a stepping motor and a hanging shaft structure assembled on an output shaft of the stepping motor, so that the rotation angle of the circular saw 200 hung on the hanging shaft structure is controlled by stepping the stepping motor, thereby achieving the purpose of controlling the gear shifting of the circular saw 200, but not limited thereto.

Specifically, in fig. 1, 3 and 4, the pivot driving mechanism 70b includes a rotating motor 71, a fixed seat 72, a gear 73 and a circular rack 74; the fixed seat 72 is fixedly connected with the marble bedplate 11 from the upper side, the circular rack 74 is fixed on the pivot seat 70a, the inner side 741 of the circular rack 74 is rotatably sleeved on the fixed seat 72, the outer side 742 of the circular rack 74 is in meshed transmission with the gear 73, the center line of the circular rack 74 is superposed with the upper and lower pivot center lines L1, the rotating motor 71 is fixed on the fixed seat 72 with the output shaft 711 arranged downwards, preferably, the rotating motor 71 is positioned between the upper and lower pivot center lines L1 and the sliding stand 20a along the front and back direction of the rack 10, so that the arrangement of the rotating motor 71 is more reasonable, the pivot seat 70a can be ensured to pivot and swing around the upper and lower pivot center lines L1 in a large range, but not limited by the above; a gear 73 is fitted to an output shaft 711 of the rotating electric machine 71; therefore, when the rotating motor 71 drives the gear 73 to rotate, the rotating gear 73 drives the circular rack 74 and the pivot swing seat 70a to pivot and swing around the upper and lower pivot swing center line L1 together, thereby achieving the purpose that the pivot swing driving mechanism 70b drives the pivot swing seat 70a to automatically pivot and swing around the upper and lower pivot swing center line L1; the structure of the pivot driving mechanism 70b is more compact and reasonable by means of the rotating motor 71, the fixed seat 72, the gear 73 and the circular rack 74. Wherein, for the purpose of raising, an intermediate plate 13 is provided between the marble slab 11 and the pivotal swing seat 70a, when the intermediate plate 13 is provided, the pivotal swing seat 70a can be pivotally assembled on the intermediate plate 13 around the upper and lower pivotal swing center line L1, and the pivotal swing driving mechanism 70b is assembled on the intermediate plate 13, therefore, the pivotal swing seat 70a and the pivotal swing driving mechanism 70b are assembled on the marble slab 11 through the intermediate plate 13.

As shown in fig. 5 to 7, the angle adjusting mechanism 40 includes a rotating motor 41, a screw rod 42, and a nut 43. The rotating motor 41 is disposed above the picosecond laser 50 along the vertical direction of the frame 10, for example, but not limited thereto, the rotating motor 41 may be pivotally assembled to the lifting slide 20b around a second pivot center line L3 parallel to the first pivot center line L2, the lead screw 42 is assembled to the output shaft 411 of the rotating motor 41 and linearly abutted to the output shaft 411, the screw 43 is slidably sleeved to the lead screw 42, and the screw 43 may be pivotally assembled to the picosecond laser 50 around a third pivot center line L4 parallel to the first pivot center line L2; therefore, the nut 43 drives the picosecond laser 50 to pivot around the first pivot center line L2 in the sliding process along the screw rod 42, specifically, in the sliding process that the rotating motor 41 drives the screw rod 42 to drive the nut 43 to move away from or close to the rotating motor 41 along the screw rod 42, the rotating motor 41 also performs adaptive pivot swing around the second pivot center line L3, so that the nut 42 which moves away from or close to the rotating motor 41 drives the picosecond laser 50 to perform angle adjustment around the first pivot center line L2, thereby realizing the accurate angle adjustment of the picosecond laser 50. Specifically, in fig. 7, the rotating motor 41 is located at the rear upper part of the picosecond laser 60b, the screw rod 42 is inclined with respect to the vertical direction of the frame 10, so that the upper end of the screw rod 42 is inclined forward and the lower end is inclined backward, and the picosecond laser 50 is pivoted with the screw nut 43 at a position behind the first pivot center line L2, so that the third pivot center line L4 formed by pivoting the screw nut 43 and the picosecond laser 50 is located behind the first pivot center line L2, and this design enables the rotating motor 41 to adjust the angle of the picosecond laser 50 more easily, smoothly and accurately through the matching of the screw rod 42 and the screw nut 43, and better enables the picosecond laser 50 to maintain a matching position with the rear knife face 211 or the side knife face 212 at the processing station.
