Description

Technical Field

[0001] This utility model relates to the field of sawing equipment technology, and in particular to a cutting device. Background Technology

[0002] Photovoltaic modules are devices used to convert sunlight into electrical energy, and are generally assembled from photovoltaic panels and four frames. Each frame is cut from profiles, and to prevent the structures of adjacent frames from interfering with each other at the corners of the photovoltaic panel, both ends of the frame need to be cut with acute angles. When the widths of the long and short sides are different, the included angle of the frames may not be 45°.

[0003] Chinese patent CN 219402598U discloses a double-head saw for solar photovoltaic steel frames. It supports the middle of the steel frame with a support frame, clamps the steel frame with a clamping device, and then uses two sawing devices to simultaneously cut from both ends of the steel frame. However, the sawing devices in this device have fixed angles, generally only capable of processing 45° cuts, which cannot meet the needs of various sawing angles.

[0004] Therefore, it is necessary to improve the cutting device to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a cutting device that makes the angle between the saw face of the circular saw and the horizontal plane adjustable, so as to adapt to the requirements of various sawing angles within a certain range.

[0006] This utility model achieves the above objective through the following technical solution: a cutting device, comprising:

[0008] A sawing assembly located inside the clearance hole includes a sawing seat rotatably connected to two bearing seats, a sawing motor mounted on the sawing seat, a circular saw driven to rotate by the sawing motor, and a translation mechanism that drives the sawing motor to move left and right relative to the sawing seat.

[0009] An angle adjustment assembly is connected to the base and drives the sawing assembly to rotate about the axis of the bearing housing.

[0010] Specifically, the angle adjustment assembly includes an angle adjustment cylinder and a rotating shaft. The tail of the angle adjustment cylinder is hinged to the lower part of the base, and the rotating shaft rotatably connects the end of the cylinder shaft of the angle adjustment cylinder to the outer side of the sawing seat.

[0011] Furthermore, the side plates on both sides of the table are a first side plate and a second side plate, respectively. The angle adjustment cylinder is located on the outside of the first side plate. The rotating shaft passes through the first side plate. The first side plate is provided with a first arc-shaped hole that avoids the movement path of the rotating shaft. The sawing seat is provided with a first locking handle that passes through the second side plate on the opposite side of the rotating shaft. The second side plate is provided with a second arc-shaped hole that avoids the movement path of the first locking handle. When the first locking handle is tightened, the angle of the sawing seat is fixed.

[0012] Furthermore, an adjustment block assembly is provided on the outer side of the first side plate. The adjustment block assembly includes an internally hollow adjustment block, an embedded block disposed within the adjustment block, and a fine-tuning bolt horizontally inserted through the embedded block. The adjustment block is close to the first arc-shaped hole, and the head of the fine-tuning bolt rests against the rotating shaft.

[0013] Furthermore, the adjusting block has several pairs of embedded slots arranged vertically opposite each other inside. At least one of the embedded slots in each pair has a round hole at the bottom. The upper and lower ends of the embedded block are respectively embedded in an embedded slot. The upper end face and / or lower end face of the embedded block are provided with threaded holes. The embedded block is fixed to the adjusting block by a second locking handle. The threaded end of the second locking handle passes through the round hole and matches the threaded hole.

[0014] Furthermore, the sawing base is provided with a protective cover, which surrounds the area of ​​the circular saw except for the cutting direction. One side of the protective cover is provided with an air intake that passes through the second side plate. The second side plate is provided with a third arc-shaped hole that avoids the movement path of the air intake. The sawing base is provided with a waste discharge ramp, which is located below the cutting direction of the circular saw.

[0015] Specifically, the platform is also provided with a material support assembly, a material pressing assembly and a pair of material clamping assemblies. The material pressing assembly is located above the material support assembly, and the two material clamping assemblies are respectively located on the left and right sides of the material pressing assembly.

[0016] Furthermore, the pressing assembly includes a pressing bracket, vertical slide rails, a lifting drive, a lifting frame, and a pressing block. The pressing bracket is disposed on the table surface. There are two vertical slide rails, which are disposed on the pressing bracket near the material support assembly. The lifting drive is located between the two vertical slide rails and drives the lifting frame to slide along the vertical slide rails.

[0034] The present invention will be further described in detail below with reference to specific embodiments.

[0035] Example 1:

[0036] like Figure 1 and Figure 2 As shown, a cutting device of this utility model includes a base 1, a sawing assembly 2, and an angle adjustment assembly 3. The base 1 includes a table surface 11 and side plates (first side plate 12 and second side plate 13) on both sides of the table surface 11. A clearance hole 111 is provided in the middle of the table surface 11. A bearing seat 14 is provided on each of the left and right sides of the clearance hole 111, and the two bearing seats 14 are coaxial. The sawing assembly 2 is located inside the clearance hole 111 and includes a sawing seat 21 rotatably connected to the two bearing seats 14, a sawing motor 22 provided on the sawing seat 21, a circular saw 23 driven to rotate by the sawing motor 22, and a translation mechanism 24 that drives the sawing motor 22 to move left and right relative to the sawing seat 21. The angle adjustment assembly 3 is connected to the base 1 and drives the sawing assembly 2 to rotate around the axis of the bearing seats 14.

[0037] The base 1 serves as the fixed foundation for the entire cutting device. The sawing of the frame is accomplished by the horizontal movement of the circular saw 23, which rotates rapidly under the drive of the sawing motor 22. The translation mechanism 24 further drives the sawing motor 22 to translate. The angle between the saw face of the circular saw 23 and the horizontal plane determines the cutting angle of the frame edge. Because the angle adjustment component 3 controls the rotation of the sawing base 21 around the horizontal axis, the angle between the saw face of the circular saw 23 and the horizontal plane is adjustable, allowing the cutting device to adapt to various sawing angle requirements within a certain range. Since the frame needs to be sawed at a position slightly higher than the table 11, the rotation axis of the sawing component 2 will also only be slightly higher than the table 11. Therefore, the entire sawing component 2 must pass through the table 11. The clearance hole 111 provides the rotation space for the sawing component 2. The angle adjustment component 3 here can be a servo motor that directly drives the sawing component 2 to rotate from one end of the rotating shaft, a motor drive mechanism that indirectly drives the rotating shaft to rotate by means of a belt drive mechanism, a motor drive mechanism that drives the sawing component 2 to rotate by means of a gear and rack, or a manual adjustment mechanism that drives the sawing component 2 to rotate by means of a gear and rack, etc.

[0038] like Figures 1 to 3 As shown, the sawing base 21 is equipped with a protective cover 25, which surrounds the area of ​​the circular saw 23 except for the cutting direction. One side of the protective cover 25 is provided with an air intake 251 that passes through the second side plate 13. The second side plate 13 is provided with a third arc-shaped hole 132 that avoids the movement path of the air intake 251. The sawing motor 22 is connected to a waste discharge ramp 27, which is located below the cutting direction of the circular saw 23.

[0039] The rapidly rotating circular saw 23 is exposed, posing a risk, so it is protected by a protective cover 25 to prevent injury to the operator. Since debris inevitably flies during sawing, the protective cover 25 also serves as a suction housing. When the suction port 251 is connected to a vacuum generator, it can simultaneously cut and remove debris, thus preventing debris from worsening the working environment. Because the parts on the sawing base 21 rotate in this technology, and the suction port 251 preferably runs under the cutting device, it generally needs to pass through the second side plate 13 and allow the suction port 251 to swing; therefore, a third arc-shaped hole 132 is provided here. After sawing, large pieces of waste fall from the edges, so a waste discharge ramp 27 is needed below the sawing position to guide the falling material and facilitate waste collection.

[0040] Example 2:

[0041] like Figure 2 and Figure 3As shown, the difference from Embodiment 1 is that the angle adjustment assembly 3 includes an angle adjustment cylinder 31 and a rotating shaft 32. The tail of the angle adjustment cylinder 31 is hinged to the lower part of the base 1, and the rotating shaft 32 rotatably connects the end of the cylinder shaft of the angle adjustment cylinder 31 to the outer side of the sawing seat 21. The angle adjustment cylinder 31 is located on the outer side of the first side plate 12, and the rotating shaft 32 passes through the first side plate 12. The first side plate 12 has a first arc-shaped hole (not exposed) that avoids the movement path of the rotating shaft 32. The sawing seat 21 has a first locking handle 26 that passes through the second side plate 13 on the opposite side of the rotating shaft 32. The second side plate 13 has a second arc-shaped hole 131 that avoids the movement path of the first locking handle 26. When the first locking handle 26 is tightened, the angle of the sawing seat 21 is fixed.

[0042] The sawing base 21 adjusts its rotation angle using the angle adjusting cylinder 31, allowing the cutting angle of the circular saw 23 to vary arbitrarily within the range of 35°-55°. After the angle adjustment is complete, the sawing base 21 can be completely fixed by tightening the first locking handle 26. Because the edge generates an unstable reaction force on the circular saw 23 during sawing, this can lead to significant operational vibration, which is detrimental to the angle adjusting cylinder 31. The placement of the angle adjusting cylinder 31 close to the first side plate 12 reduces the sway amplitude of the angle adjusting assembly 3 during sawing, thus protecting the various components of the angle adjusting assembly 3.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, an adjustment block assembly 4 is also provided on the outer side of the first side plate 12. The adjustment block assembly 4 includes an internally hollow adjustment block 41, an embedded block 42 disposed in the adjustment block 41, and a fine-tuning bolt 43 horizontally inserted on the embedded block 42. The adjustment block 41 is close to the first arc-shaped hole, and the head of the fine-tuning bolt 43 abuts against the rotating shaft 32.

[0044] Because the cylinder shaft extending from the angle adjusting cylinder 31 is the part most susceptible to working vibrations, the torque of the sawing seat 21 can be distributed by the adjusting block assembly 4 during actual operation. The adjusting block 41 and the insert block 42 similarly restrict the range of motion of the rotating shaft 32. After the angle adjustment is complete, the fine-tuning bolt 43 can be adjusted to a horizontal position relative to the insert block 42, so that most of the load-bearing force at the outer end of the rotating shaft 32 falls on the fine-tuning bolt 43, rather than entirely acting on the cylinder shaft of the angle adjusting cylinder 31. This better protects the components.

[0045] like Figure 4As shown, the adjusting block 41 has several pairs of insert grooves 411 arranged vertically opposite each other inside. At least one insert groove 411 in each pair of insert grooves 411 has a round hole 412 at the bottom. The upper and lower ends of the insert block 42 are respectively inserted into an insert groove 411. The upper end face and / or lower end face of the insert block 42 are provided with threaded holes (not exposed). The insert block 42 is fixed to the adjusting block 41 by a second locking handle 44. The threaded end of the second locking handle 44 passes through the round hole 412 and matches the threaded hole.

[0046] In this embodiment, the sawing base 21 has a 20° swing range, which results in an adjustment range of several decimeters for the rotating shaft 32. This adjustment range is easy to control for the angle adjustment cylinder 31, but the adjustment distance is too large for the fine-tuning bolt 43. Therefore, multiple insert slots 411 are used for the insert block 42 to select from. The distance between adjacent insert slots 411 can be several centimeters. This allows the insert block 42 and the fine-tuning bolt 43 to be removed from the adjustment block 41 as a whole and then moved into the appropriate insert slot 411, thereby quickly shortening the adjustment stroke. This makes adjusting the distance using the fine-tuning bolt 43 more time-efficient. After the insert block 42 is moved, the second locking handle 44 is used to lock the position, thereby preventing the whole assembly from falling off the adjustment block 41.

[0047] Example 3:

[0048] like Figure 1 , Figure 2 and Figure 5 As shown, the difference from Embodiment 1 is that the table 11 is also provided with a material support assembly 5, a material pressing assembly 6, and a pair of material clamping assemblies 7. The material pressing assembly 6 is located above the material support assembly 5, and the two material clamping assemblies 7 are respectively located on the left and right sides of the material pressing assembly 6.

[0049] During sawing, the position of the frame cannot be moved arbitrarily, otherwise the cross-section will not achieve the ideal structural dimensions. Therefore, the ends of the frame need to be supported by the material support assembly 5, the pressure assembly 6, and the clamping assembly 7 to achieve the positional stability requirements of the frame.

[0050] like Figure 2 and Figure 5As shown, the material pressing assembly 6 includes a material pressing bracket 61, vertical slide rails 62, a lifting drive 63, a lifting frame 64, and a pressing block 65. The material pressing bracket 61 is mounted on the table surface 11. There are two vertical slide rails 62, which are located on the material pressing bracket 61 near the material supporting assembly 5. The lifting drive 63 is located between the two vertical slide rails 62 and drives the lifting frame 64 to slide along the vertical slide rails 62. The pressing block 65 is located above the material supporting assembly 5 and connected to the lifting frame 64. The material supporting assembly 5 includes several material supporting bolts 51 vertically connected to the table surface 11, a stop block 52 located below the pressing block 65, and lower material supporting mechanisms 53 respectively located below the stop block 52 on both sides. The material clamping assembly 7 includes a horizontally arranged material clamping cylinder 71 and a clamping block 72 driven by the material clamping cylinder 71 to move closer to and away from the stop block 52.

[0051] During the sawing process, the lower part of the frame is uneven, so it needs to be initially positioned using the material support bolt 51. The material support bolt 51 can be flexibly controlled at its height on the table 11 to adapt to different frame structures. Because there is ample space above the table 1, the lifting frame 64 can be directly raised and lowered using the lifting drive 63, thereby pressing the frame down with the pressure block 65. The lower material support mechanism 53 and the clamping block 72 abut against the remaining parts of the frame from below and the side, respectively, thus completely fixing the position of the frame.

[0052] like Figure 5 As shown, the lower material support mechanism 53 includes a lever 531, a material support cylinder 532, and an adaptive support block 533. The middle part of the lever 531 is rotatably connected to the stop block 52. The cylinder shaft of the material support cylinder 532 is hinged to one end of the lever 531. The adaptive support block 533 is rotatably connected to the other end of the lever 531. The pressure block 65 is vertically opposite to the adaptive support block 533. The material support cylinder 532 is located outside the movement path of the sawing assembly 2.

[0053] Because the circular saw 23 needs to cut the edge of the frame at an angle, and the material support assembly 5 needs to be positioned relatively close to the cutting line to provide better stability, the movement path of the circular saw 23 limits the space occupied by the material support assembly 5. Therefore, the support block cannot be directly driven by the cylinder located directly below; instead, the material support cylinder 532 is positioned further away, and the adaptive support block 533 is raised and lowered by lever 531. The adaptive support block 533 has a degree of freedom of rotation, so it can swing as a whole while rotating to conform to the lower surface of the outer frame.

[0054] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
