DETAILED DESCRIPTION
[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] Example
[0027] Combined with Figure 1-5 This embodiment provides a template cutting machine that can realize multiple cutting modes, specifically, Figure 1 The template cutting machine comprises a cutting platform 2, a machine head body 1 and a two-dimensional motion structure 3 installed on the cutting platform 2 for driving the machine head body 1 to reciprocate in the horizontal two-dimensional space above the cutting platform 2, wherein the two-dimensional motion structure 3 is a common structure in the art and can be in various forms, for example, a first horizontal reciprocating motion structure parallel to the x-axis in the spatial rectangular coordinate system xyz-o and a second horizontal reciprocating motion structure parallel to the y-axis and installed on the cutting platform 2, wherein the sliding platform in the first horizontal reciprocating motion structure is connected to the machine head body 1 through a vertical plate 4 The first horizontal reciprocating motion structure is connected to the sliding platform in the second horizontal reciprocating motion structure, and then the combined movement of the two horizontal reciprocating motion structures can realize the two-dimensional plane movement of the head body 1 above the top of the cutting platform 2. Secondly, in order to facilitate the adsorption and cutting of the template on the top of the cutting platform 2, in this embodiment, negative pressure holes 44 are firstly evenly opened on the top of the cutting platform 2, and each negative pressure hole 44 is respectively connected to the negative pressure pipe network 45 at the bottom of the cutting platform 2, and the negative pressure pipe network 45 is connected to the external negative pressure device, so that the template laid thereon can be effectively adsorbed; Figure 1 A cover is provided on the main body of the machine head to show the internal structure of the main body 1. Figure 2-5 The machine cover has been removed.
[0028] In particular, in order to avoid the poor adsorption effect of the negative pressure hole 44 at the edge of the template, in this embodiment, the top outer edge of the cutting platform 2 is evenly provided with edge adsorption holes 46 that are connected to the negative pressure pipe network 45 and have an inner diameter larger than the inner diameter of the negative pressure hole 44, so as to facilitate the firm adsorption of the template edge.
[0029] In particular, the improvement of the equipment in this embodiment mainly lies in the head body 1, specifically:
[0030] The head body 1 in this embodiment includes a guide rail 5 fixedly mounted on a vertical plate 4, and an upper sliding plate 8 and a lower sliding plate 9 are arranged on the outer side of the guide rail 5 from top to bottom, and the upper sliding plate 8 and the lower sliding plate 9 are connected by a return spring 7, that is, the two are in close contact under the action of the return spring 7 under normal conditions. Secondly, a plurality of sliders 6 sleeved on the guide rail 5 are fixedly mounted on the side wall of the upper sliding plate 8 facing the guide rail 5 and the side wall of the lower sliding plate 9 facing the guide rail 5, so that the upper sliding plate 8 and the lower sliding plate 9 are connected. The sliding plates 9 can slide up and down on the guide rails 5; in order to facilitate cutting of the template, in this embodiment, the components of the head body 1 also include a driving motor 11 fixedly mounted on the side wall of the upper sliding plate 8 away from the guide rail 5, and a milling cutter 12 is installed at the bottom end of the driving motor 11. In order to make the milling cutter 12 move downward to cut the template when necessary, in this embodiment, the top end of the upper sliding plate 8 passes through a lifting structure 10 that can drive it to slide up and down under the guidance of the guide rail 5, thereby effectively realizing the up and down movement of the milling cutter 12;
[0031] In particular, in order to facilitate setting different cutting depths according to different templates, in this embodiment, a horizontal support plate 13 fixedly connected to the lower sliding plate 9 is provided directly below the milling cutter 12, and an adjustment notch is provided on the horizontal support plate 13 and is located directly below the milling cutter 12. A dust collection bin 14 is provided in the adjustment notch, and an insertion hole 15 for inserting the milling cutter 12 is provided at the top of the dust collection bin 14, and an exit hole 16 for the milling cutter 12 to pass through is provided at the bottom thereof, so as to facilitate cutting, wherein the top side wall of the dust collection bin 14 A support arm 17 is connected to the upper portion, and the main body is arranged above the horizontal support plate 13. An adjusting bolt 18 is arranged above the end of the support arm 17 away from the dust collection bin 14, and the bottom end is threadedly connected to the support arm 17 and the horizontal support plate 13 in sequence. When the bottom of the support arm 17 is adjusted to fit the top of the horizontal support plate 13 by adjusting the adjusting bolt 18, the lowest point of the bottom end of the milling cutter 12 is located in the horizontal plane where the part of the bottom of the dust collection bin 14 is within the set distance range outside the through hole 16, that is, the milling cutter 12 will not leak out at this time;
[0032] When cutting templates of different thicknesses, it is only necessary to clamp the sample of the corresponding template between the support arm 17 and the horizontal support plate 13 and then tighten the adjusting bolt 18. At this time, the dust suction bin 14 moves upward relative to the milling cutter 12, and the height of the milling cutter 12 leaking out of the dust suction bin 14 is equal to the thickness of the template. Then the milling cutter 12 moves downward for cutting, and the cutting thickness is equal to the thickness of the template, thereby effectively achieving the purpose of quickly setting the cutting thickness and avoiding the defects of traditional manual adjustment.
[0033] In particular, in order to collect the debris generated by cutting, in this embodiment, the vertical wall of the dust collection bin 14 is connected to the dust exhaust pipe 47, and the outer end of the dust exhaust pipe 47 is connected to the external dust collection device, which is a structure such as a dust collector, so that the debris generated by the milling cutter 12 is first gathered in the dust collection bin 14 and then guided by the dust exhaust pipe 47 to be sucked away, thereby avoiding the defect of debris flying;
[0034] In particular, because in some cases it is not necessary to cut through the template and only grooves need to be carved on its surface, at this time, by clamping the template sample between the support arm 17 and the horizontal support plate 13, the height of the milling cutter 12 leaking out of the dust collection bin 14 will be too large, and then the corresponding purpose cannot be achieved. In order to reduce the height of the milling cutter 12 at this time, in this embodiment, the lower sliding plate 9 is rotated toward the side wall of the guide rail 5 to install a driving wheel 19, and a driving cross bar 20 is arranged above the driving wheel 19. One end of the driving cross bar 20 is rotatably connected to the upper sliding plate 8, and the other end is connected to a driving cross bar 20 that can be driven to rotate around it and the upper sliding plate 8. The plate 8 is connected to a rotary drive structure 21 for rotational movement at the rotation connection. The rotary drive structure 21 is located outside the upper sliding plate 8 and is fixedly connected to the upper sliding plate 8 through a connecting piece. The rotary drive structure 21 can drive the driving wheel 19 below it downward in the process of driving the driving cross bar 20 to rotate downward, thereby driving the lower sliding plate 9 to slide downward, thereby driving the dust collection bin 14 downward. In this case, the height of the milling cutter 12 leaking out of the dust collection bin 14 can be effectively reduced under the condition that the height of the milling cutter 12 remains unchanged, thereby achieving a half-template height cutting, avoiding the aforementioned defects and enriching the functions of the equipment.
[0035] In particular, in the present embodiment, when the end portion where the driving cross bar 20 is connected to the rotating driving structure 21 is at the highest horizontal elevation during the rotating movement, the top of the driving wheel 19 contacts the bottom of the driving cross bar 20 and at this time, the top of the lower sliding plate 9 is tightly pressed against the bottom end of the upper sliding plate 8 under the action of the return spring 7.
[0036] The purpose of the above arrangement is to enable the driving cross bar 20 to always maintain contact with the driving wheel 19, thereby facilitating precise control of the equipment.
[0037] Working principle of the equipment:
[0038] When it is necessary to cut the template to the same thickness, the template sample is clamped between the support arm 17 and the horizontal support plate 13 and the adjusting bolt 18 is tightened. At this time, the height of the milling cutter 12 leaking out of the dust suction bin 14 is equal to the thickness of the template, and the rotary drive structure 21 is not started. Then the lifting structure 10 drives the milling cutter 12 downward, and the template can be cut to the same thickness. After the cutting is completed, the milling cutter 12 is reset.
[0039] When it is necessary to cut to a height equal to half the thickness of the template, the template sample is clamped between the support arm 17 and the horizontal support plate 13 and the adjusting bolt 18 is tightened. At this time, the height of the milling cutter 12 leaking out of the dust collection bin 14 is equal to the thickness of the template. Then the rotary drive structure 21 is activated to make the dust collection bin 14 descend a certain height relative to the milling cutter 12, such as the height of half the template. Then the current height of the dust collection bin 14 is maintained, and the lifting structure 10 is activated to make the whole formed by the milling cutter 12 and the dust collection bin 14 descend, and cutting to a height equal to half the template is performed. After completion, the milling cutter 12 is reset.
[0040] In particular, in order to prevent the dust collection bin 14 from descending to a height exceeding the target height driven by the rotary drive structure 21, and to improve the accuracy of the device, in the present embodiment, a limited eccentric wheel 22 is provided between the driving wheel 19 and the rotary drive structure 21, and a horizontal rotary hole is provided on the upper sliding plate 8, the center of the limited eccentric wheel 22 is located on the extension line of the axis of the rotary hole, and a horizontal cylinder 23 with one end thick and the other end thin is provided on the side of the upper sliding plate 8 away from the guide rail 5, the outer diameter of the thinner part of the horizontal cylinder 23 is the same as the inner diameter of the rotary hole, and the part passes through the rotary hole and is vertically connected to the center of the limited eccentric wheel 22 At the same time, a hexagonal hole is provided on the end of the thicker part of the horizontal cylinder 23, so that the horizontal elevation of the highest point of the top of the limiting eccentric wheel 22 can be adjusted through the hexagonal hole. In order to lock the current state of the limiting eccentric wheel 22, in this embodiment, a locking threaded hole 24 connected to the rotating hole is also provided on the upper sliding plate 8, and a locking bolt 25 is provided on the outer side of the locking threaded hole 24. The locking bolt 25 passes through the locking threaded hole 24 toward the end of the locking threaded hole 24 and presses against the part of the horizontal cylinder 23 in the rotating hole; secondly, the driving wheel 19, the limiting eccentric wheel 22, the driving cross bar 20, etc. meet the following conditions:
[0041] When the limiting eccentric wheel 22 rotates to the highest horizontal elevation of its top, its top contacts the bottom of the driving cross bar 20 and the top of the driving wheel 19 contacts the bottom of the driving cross bar 20 at this time. At the same time, the lower sliding plate 9 is tightly pressed against the upper sliding plate 8 under the action of the return spring 7, and the top of the driving wheel 19 also contacts the driving cross bar 20. Then, when the limiting eccentric wheel 22 is rotated by the horizontal cylinder 23 to make the horizontal elevation of the highest point of its top smaller, it is no longer in contact with the driving cross bar 20 at this time, while the driving cross bar 20 still maintains contact with the driving wheel 19. Then, when the rotating driving structure 21 causes the driving cross bar 20 to move downward, it drives the dust collection bin 14 downward through the driving wheel 19 until the driving cross bar 20 contacts the limiting eccentric wheel 22. With the locking effect of the locking bolt 25, the driving cross bar 20 cannot move downward, and the dust collection bin 14 cannot move downward either, thereby achieving the purpose of the downward height of the obtained dust collection bin 14, thereby achieving precise control of the equipment and improving the cutting accuracy.
[0042] In particular, because the space inside the machine head body 1 is relatively narrow, in order to improve the space utilization and ensure the operating accuracy of the equipment, in this embodiment, the driving cross bar 20 is specifically composed of a first cross bar 26, a vertical connecting rod (27, a second cross bar 28 and a vertical driving rod 29, one end of the first cross bar 26 is rotatably connected to the upper sliding plate 8 and the driving wheel 19 is located below it and keeps contact with it, the other end of the first cross bar 26 is connected to the bottom end of the vertical connecting rod (27, the top end of the vertical connecting rod (27 is connected to one end of the second cross bar 28, the other end of the second cross bar 28 is connected to the vertical driving rod 29, the top end of the vertical driving rod 29 is connected to the rotating driving structure 21, the limiting eccentric wheel 22 is located below the second cross bar 28, and the limiting eccentric wheel 22 and the driving wheel 19 meet the above conditions.
[0043] That is, by setting the driving cross bar 20 to be an inverted Z-shaped structure, the force arm formed by the driving cross bar 20 can be effectively improved, thereby facilitating the operation of the equipment and avoiding the defects when the driving cross bar 20 is a horizontal bar.
[0044] In particular, in the present embodiment, in order to further improve the space utilization rate of the equipment, the composition of the rotary drive structure 21 includes a first electromagnet core 30 and a first electromagnet coil 31 which is located on the outer side of the upper sliding plate 8 and fixedly connected to the upper sliding plate 8 through a connecting piece. The first electromagnet core 30 is located in a cavity in the first electromagnet coil 31. When the first electromagnet coil 31 is turned on, the first electromagnet core 30 can move downward. Secondly, in order to facilitate driving the driving cross bar 20 downward, the top end of the vertical driving rod 29 is arranged in the first electromagnet coil 31 and keeps contact with the bottom end of the first electromagnet core 30. At the same time, the equipment satisfies: when the first electromagnet coil 31 is turned on to drive the first electromagnet core 30 downward, it can synchronously drive the top end of the vertical driving rod 29 to move downward, thereby driving the entire driving cross bar 20 to rotate downward. At the same time, when the first electromagnet core 30 moves downward to the extreme position, the top end of the vertical driving rod 29 is still in the first electromagnet coil 31.
[0045] Through the above arrangement, the driving cross bar 20 can be effectively driven to rotate by means of the cooperation between the first electromagnet coil 31 and the first electromagnet core 30, and the device has a simple structure and small space occupation, which can improve the space utilization rate of the device.
[0046] In particular, in the present embodiment, the lifting structure 10 comprises a stepper motor 32, a driving arm 33 and a connecting arm 34, wherein the stepper motor 32 is mounted on the vertical plate 4, and its output shaft is perpendicular to the upper sliding plate 8 and is located between the upper sliding plate 8 and the vertical plate 4, the output shaft of the stepper motor 32 is vertically fixedly connected to one end of the driving arm 33, the other end of the driving arm 33 is rotatably connected to the connecting arm 34, and the other end of the connecting arm 34 is rotatably connected to the top end of the upper sliding plate 8;
[0047] Furthermore, through the above, when the stepper motor 32 is in operation, the driving arm 33 can drive the connecting arm 34 to drive the upper sliding plate 8 to slide upward under the guidance of the guide rail 5, thereby driving the milling cutter 12 to move up and down.
[0048] In particular, in the present embodiment, in order to avoid the equipment being unable to float up autonomously during cutting and thus causing difficulty in operation due to an uneven template, in the present embodiment, a rectangular through hole 35 is opened on the top of the upper sliding plate 8, and a vertical guide shaft 48 is fixedly installed in the rectangular through hole 35, and a guide block 37 and a tight-holding spring 36 are sequentially sleeved on the vertical guide shaft 48 from top to bottom, that is, under normal circumstances, the tight-holding spring 36 acts on the guide block 37 to keep its top in contact with the top of the rectangular through hole 35. When facing an uneven template, the reaction force from the template can compress the tight-holding spring 36 to make the upper sliding plate 8 move up a certain distance, and can restore to its initial position under the action of the tight-holding spring 36. In this process, the height of the milling cutter 12 leaking out of the dust collection bin 14 remains unchanged, which can effectively ensure the cutting depth.
[0049] In particular, in order to further enrich the functions of the head body 1, in the present embodiment, a C-shaped frame is provided below the vertical driving rod 29 which does not affect its rotational movement and is fixedly connected to the upper sliding plate 8, and a second electromagnet core 38 is provided in the C-shaped frame, and a second electromagnet coil 39 is sleeved on the outer side of the second electromagnet core 38, and a connecting platform 40 is fixedly installed at the bottom of the second electromagnet coil 39, and a fixing frame 41 for clamping a writing pen is fixedly installed on the end of the connecting platform 40 away from the vertical plate 4, and a knife holder 42 for clamping a cutting knife is also fixedly installed on the side wall of the bottom vertical wall of the upper sliding plate 8 adjacent to the horizontal support plate 13.
[0050] Through the above arrangement, due to the fixed installation of the second electromagnet core 38, the second electromagnet coil 39 will move downward relative to the second electromagnet core 38 when it is running, thereby driving the fixed frame 41 connected to it through the connecting platform 40 to move downward. When a writing pen is fixedly installed in the fixed frame 41, the second electromagnet coil 39 can drive the writing pen downward until it contacts the template and perform corresponding painting along with the movement of the head body 1, thereby enriching the function of the equipment.
[0051] By setting up the tool holder 42, when the cutter is fixedly installed in the tool holder 42 and the support arm 17 is kept in contact with the horizontal support plate 13, the lifting structure 10 is activated, so that the cutter can move down to the cutting height and move along with the movement of the head body 1, thereby achieving cutting of corresponding shapes, which further enriches the function of the equipment.
[0052] In particular, in order to facilitate the replacement of the template sample clamped between the support arm 17 and the horizontal support plate 13, and at the same time to balance the force on the dust collection bin 14, in the present embodiment, the support arm 17 and the adjusting bolt 18 constitute a whole that is specifically two and symmetrically installed on both sides of the top of the dust collection bin 14, the main part of each support arm 17 is above the horizontal support plate 13, the bottom end of each adjusting bolt 18 is fixedly connected to the horizontal support plate 13, and each adjusting bolt 18 is sleeved with an adjusting sleeve 43 that is thicker at the top and thinner at the bottom. The thicker upper part of the adjusting sleeve 43 is arranged above the corresponding support arm 17 and the thinner lower part is located in the support arm 17, and the part of each adjusting bolt 18 located in the corresponding support arm 17 is threadedly connected to the thinner part of the corresponding adjusting sleeve 43, and the outer wall of the thinner part of each adjusting sleeve 43 is a smooth structure and the outer diameter of the part is the same as the inner diameter of the hole on the corresponding support arm 17 for accommodating it.
[0053] That is, when the adjusting sleeve 43 is screwed, under the condition that the adjusting bolt 18 is fixed, the adjusting sleeve 43 can move up and down relative to the corresponding adjusting bolt 18. When the adjusting sleeve 43 moves up relative to the support arm 17, the corresponding support arm 17 will no longer be covered by the thicker upper part of the adjusting sleeve 43, so that the template between the support arm 17 and the horizontal support plate 13 can be effectively replaced. When the replacement is completed, the adjusting sleeve 43 is moved down so that the thicker upper part of the adjusting sleeve 43 covers the corresponding support arm 17 to complete the locking purpose.
[0054] In particular, in the present embodiment, the bottom end of the dust collection bin 14 is a movable cover with an open top, the top outer wall of the movable cover is threadedly connected to the bottom inner wall of the vertical part of the dust collection bin 14, a through hole 16 is provided at the bottom center of the movable cover, the periphery of the through hole 16 is within a set distance range to be a horizontal plane, and the other parts of the bottom of the movable cover are in a structural shape with a gradually increasing horizontal elevation from the inside to the outside, that is, the bottom of the movable cover is an arc-shaped convex structure, and the center of the convex structure is a horizontal plane and is provided with a through hole 16, which facilitates the movement of the overall equipment during the cutting process.
[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
