[0034] Reference Figures 1 to 12 The sawing machine with a conveniently adjustable saw blade 120 provided in the embodiment of the present application includes a sawing head 100 and a first adjusting device 200 .
[0035] The saw head 100 has a rotatable saw blade 120 so that it can be used for automotive parts or other products that need to be cut.
[0036] Among them, the sawing head 100 is rotatably set on the first adjusting device 200, and the first adjusting device 200 includes a first adjusting member 220, a first transmission component and a locking structure. The first adjusting member 220 is connected to the sawing head 100 through the first transmission component. The first adjusting member 220 is rotated to adjust the angle between the saw blade 120 and the horizontal plane to be able to be adjusted between 0° and 90°. The locking structure is used to limit the rotation of the sawing head 100.
[0037] In some embodiments, the sawing machine also includes a feeding device 400 and a rotating device 500. The first adjusting device 200 is arranged on the feeding device 400. The feeding device 400 is used to adjust the horizontal distance of the saw blade 120 from the product. The feeding device 400 is arranged on the rotating device 500. The rotating device 500 is used to adjust the orientation of the saw blade 120 to meet the cutting requirements of products of different shapes.
[0038] Specifically, the feeding device 400 includes a mounting platform 410, a driving structure and a sliding member 420. The sliding member 420 is slidably arranged on the mounting platform 410 so that the sliding member 420 can move linearly in the horizontal direction. The driving structure is used to drive the sliding member 420 to move. Further, the sliding member 420 is slidably arranged on the mounting platform 410 through a linear guide structure, the first adjustment device 200 is fixed on the sliding member 420, the driving structure includes a first motor 430 and a lead screw transmission member, the lead screw transmission member 440 is rotatably arranged on the mounting platform 410 through a lead screw support seat, the first motor 430 is connected to the lead screw transmission member 440 through a coupling, the lead screw nut of the lead screw transmission member 440 is fixedly connected to the sliding member 420, and the rotation of the motor is converted into the linear motion of the sliding member 420 through the lead screw transmission member 440 to realize the feeding operation of the saw blade 120.
[0039] Specifically, the rotating device 500 includes a rotating platform and a rotating motor for driving the rotating platform to rotate, and the mounting platform 410 of the feeding device 400 is fixed to the rotating platform.
[0040] When performing sawing operations, first position and fix the product, then adjust the saw blade 120 of the sawing head 100 according to the cutting surface required by the product. When adjusting the saw blade 120, loosen the locking structure to release the restriction on the sawing head 100, and then rotate and adjust the first adjustment member 220. Under the transmission action of the first transmission member, the angle of the saw blade 120 can be accurately and quickly adjusted. At the same time, the existence of the first transmission member also enables the rotation adjustment of the sawing head 100 to be performed in a more labor-saving manner. After the saw blade 120 is adjusted to the required angle, the position is further fixed by the locking structure to prevent the angle of the saw blade 120 from deviating during use. Then, the feeding device 400 is activated to drive the saw blade 120 to saw the product that has been positioned and fixed. If there is a bent product later, the orientation of the sawing head 100 can also be adjusted by the rotating device 500, and then the feeding device 400 is used to go to the corresponding position for cutting.
[0041] Compared with the prior art, the present application abandons the solution of servo-adjusting the angle of the saw blade 120 of the sawing head 100, and adopts a simple mechanical structure. The inclination angle of the saw blade 120 can be quickly adjusted by simply rotating the first adjustment member 220 to meet the cutting angle requirements of different products. In addition, the sawing machine of the present application has a simple structure and requires fewer parts, which greatly reduces the weight of the sawing machine, further reduces the manufacturing cost, and is convenient for later maintenance.
[0042] The first adjusting device 200 includes a first mounting seat 210, and the first adjusting member 220 and the sawing head 100 are both rotatably arranged on the first mounting seat 210. The rotation center of the first adjusting member 220 is perpendicular to the rotation center of the sawing head 100, and the first transmission component is used to convert the rotation of the first adjusting member 220 into the rotation of the sawing head 100.
[0043] In the embodiment of the present application, the first adjusting member 220 is horizontally arranged, and the rotation center of the sawing head 100 is also horizontally arranged. The rotation center of the first adjusting member 220 is perpendicular to the rotation center of the sawing head 100, which can greatly reduce the volume of the first adjusting device 200. At the same time, due to the presence of the first transmission component, the rotation of the first adjusting member 220 can be converted into the rotation of the sawing head 100, which facilitates the transmission of force.
[0044] In some specific embodiments, Figure 4 As shown, the first mounting seat 210 is provided with a first mounting plate 211, and the first adjusting member 220 is rotatably disposed on the first mounting plate 211 through a bearing to reduce the friction force required to rotate the first adjusting member 220 and make the rotation smoother.
[0045] Further, such as Figures 3 to 6 As shown, the first transmission component includes a first transmission member 230 and a second transmission member 240. The first transmission member 230 is slidably disposed on the first mounting seat 210. The first transmission member 230 is threadedly connected to the first adjustment member 220. The second transmission member 240 is fixed to the rotation center position of the sawing head 100, and the second transmission member 240 is meshedly connected to the first transmission member 230.
[0046] Specifically, a slide rail 213 is provided on the first mounting seat 210, and a slide groove matched with the slide rail 213 is provided on the first transmission member 230. The cooperation between the slide rail 213 and the slide groove enables the first transmission member 230 to reciprocate. The first adjusting member 220 is connected to the first transmission member 230 by a thread so that the rotation of the first adjusting member 220 can be converted into the linear movement of the first transmission. Since the second transmission member 240 is meshed and connected with the first transmission member 230, the linear movement of the first transmission member 230 can be converted into the rotation of the second transmission member 240, thereby driving the sawing head 100 to rotate to achieve the inclination adjustment of the saw blade 120.
[0047] The meshing transmission mode allows the saw head 100 to be driven to rotate with relatively little effort by slightly rotating the first adjusting member 220. The adjustment is convenient, and any subsequent component that has a problem can be quickly repaired without involving inspection of the electrical circuit, and the maintenance is convenient.
[0048] In a specific embodiment, the first transmission member 230 is a rack, and the second transmission member 240 is a gear. Force transmission is achieved through the cooperation between the rack and the gear.
[0049] Of course, in some other embodiments, the first adjusting member 220 may also be a worm, and the first transmission member may also be a worm wheel. The cooperation of the worm wheel and the worm can drive the sawing head 100 to rotate, which is also a more labor-saving structure.
[0050] In some embodiments, the locking structure includes a locking member 250 and an arc groove 212 that passes through both sides of the first mounting seat 210. The center of the arc groove 212 coincides with the rotation axis of the sawing head 100. The locking member 250 passes through the arc groove 212 and is threadedly connected to the sawing head 100, so that a portion of the sawing head 100 is pressed against the first mounting seat 210 by the threaded structure, thereby limiting the rotation of the sawing head 100.
[0051] In the embodiment of the present application, the locking member 250 has a pressing cap and a stud. The stud passes through the arc groove 212 and is threadedly connected to the sawing head 100. The pressing cap presses against one side of the first mounting seat 210, and the sawing head 100 is located on the other side of the first mounting seat 210.
[0052] In some embodiments, a first scale is provided on the first mounting seat 210, a first indicating arrow is provided on the first transmission member 230, and the setting direction of the first scale is parallel to the sliding direction of the first transmission member 230. The specific range of adjustment can be quickly observed through the cooperation of the first scale and the first indicating arrow. At the same time, in order to facilitate quick adjustment, a mark can be made on the first scale, and quick and accurate adjustment can be achieved by directly moving to the corresponding position next time.
[0053] Specifically, the first scale is fixed on the slide rail 213, the first indicating arrow is fixed on the first transmission member 230, the smallest unit of the first scale is millimeter, and the tip of the first indicating arrow is close to the scale of the first scale.
[0054] In some embodiments, Figures 7 to 9 As shown, the sawing machine with easily adjustable saw blade 120 also includes a second adjusting device 300. The two ends of some products may not be on the same horizontal plane, and the second adjusting device 300 is used to adjust the height of the sawing head 100 in the vertical direction to meet the end sawing requirements of different products.
[0055] Specifically, the second adjustment device 300 includes a second adjustment member 320 and a second mounting seat 310. The second adjustment member 320 is rotatably set on the first mounting seat 210. The first mounting seat 210 is slidably set on the second mounting seat 310. The first mounting seat 210 can slide in the vertical direction. The second adjustment member 320 is connected to the second mounting seat 310 through a transmission structure so that the second adjustment member 320 can adjust the first mounting seat 210 in the vertical direction.
[0056] Specifically, the transmission structure can convert the rotation of the second adjusting member 320 into the linear motion of the second mounting seat 310 , that is, the second mounting seat 310 can be moved up and down by rotating and adjusting the second adjusting member 320 .
[0057] In the embodiment of the present application, the second adjusting member 320 has a screw portion, and the second mounting seat 310 is provided with a screw hole that matches the screw portion, and the screw portion and the screw hole cooperate to form a transmission structure. Specifically, the first mounting seat 210 is slidably disposed on the second mounting seat 310 through a guide rail slider structure, and the second adjusting member 320 is rotatably disposed on the first mounting seat 210 through a bearing, and the second mounting seat 310 has a docking portion 330, and the screw hole is disposed on the docking portion 330.
[0058] Furthermore, a second scale 340 is provided on the first mounting seat 210, and a second indicating arrow 350 is provided on the second mounting seat 310, and the setting direction of the second scale 340 is parallel to the sliding direction of the first mounting seat 210. The height range of the adjustment can be quickly observed through the cooperation between the second scale 340 and the second indicating arrow 350. At the same time, in order to facilitate quick adjustment, a mark can be made on the second scale 340, and the next time, it can be directly moved to the corresponding position to achieve quick and accurate adjustment.
[0059] In some embodiments, Figures 10 to 12 As shown, the sawing head 100 includes a third mounting seat 110, a driving member 140 and a third adjusting member 150. The third mounting seat 110 is rotatably disposed on the first adjusting device 200 through a rotating shaft. The saw blade 120 is rotatably disposed on the third adjusting member 150 through a transmission shaft 130. The driving member 140 is used to drive the saw blade 120 to rotate. The third adjusting member 150 is inserted into the third mounting seat 110. The third adjusting member 150 can be adjusted to be plugged in and connected to the transmission shaft 130 to limit the rotation of the transmission shaft 130.
[0060] Specifically, the driving member 140 is a motor, which is fixed to the third mounting seat 110, and the motor is connected to the transmission shaft 130 through a synchronous wheel and a synchronous belt. The transmission shaft 130 is rotatably mounted on the third mounting seat 110 through a bearing, and a locking hole is provided on the transmission shaft 130 corresponding to the position of the third adjustment member 150. When the saw blade 120 needs to be repaired or disassembled, the third adjustment member 150 is adjusted and inserted into the locking hole to limit the rotation of the saw blade 120, thereby facilitating replacement.
[0061] To ensure safety in use and to avoid forgetting to pull the third adjustment member 150 out of the transmission shaft 130 after repairing the saw blade 120, a sensor 160 is set on the third mounting seat 110. The sensor 160 is used to sense whether the third adjustment member 150 is pulled out of the third mounting seat 110. The saw blade 120 can only start to rotate after the third adjustment member 150 is pulled out of the third mounting seat 110.
[0062] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
