Description

Technical Field

[0001] The present invention relates to the technical field of cutting, and particularly relates to a positioning cutting device for processing the metal surface of a notebook shell. Background Art

[0002] The notebook shell has a metal surface. In order to increase the aesthetic property, smooth metal wires (with a circular, elliptical or rectangular cross-section) are inlaid around the metal surface, and the bright strip effect is achieved by using the light reflection property of the smooth surface of the metal wires.

[0003] When the metal wires are produced, their lengths are relatively long. Therefore, during actual use, it is necessary to cut the metal wires to a fixed length according to the inlaid perimeter around the notebook.

[0004] After retrieval, the patent with the Chinese patent publication number CN209550471U discloses a metal wire cutting device, which includes a front compaction mechanism and a rear compaction mechanism with the same structure. The front compaction mechanism and the rear compaction mechanism are symmetrically arranged on both sides of the cutting mechanism. The front compaction mechanism and the rear compaction mechanism both include a compaction seat, a horizontal compaction component, a tensioning component and an automatic compaction component. The cutting mechanism includes a cutting base, a hydraulic cylinder, a hydraulic push rod and a cutting blade.

[0005] The above patent has the following deficiencies: It uses the front compaction mechanism and the rear compaction mechanism on both sides to limit the metal wire, and then uses the cutting mechanism in the middle to cut. When the metal wire in the middle is cut off, it is necessary to manually pull the metal wire into the rear compaction mechanism again, so continuous cutting of multiple segments cannot be achieved.

[0006] Therefore, the present invention proposes a positioning cutting device for processing the metal surface of a notebook shell. Summary of the Invention

[0007] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a positioning cutting device for processing the metal surface of a notebook shell.

And a tool rest matching with the cutter is arranged on the top of the base, and a tool groove for avoiding the cutter is opened on the inner wall of the tool rest; A motor is fixed to the outer wall of the bottom of the base by bolts. A gear is key-connected to the output shaft of the motor. The turntable is meshed with the outer wall of the gear through a tooth groove arranged on the side wall of its bottom.

[0009] Preferably, the traction switching mechanism includes an "h"-shaped frame fixed to the side wall of the turntable and a clamping plate slidably connected above the "h"-shaped frame through a second guide rod. Anti-slip pads are fixed to the upper surface below the "h"-shaped frame and the outer wall of the bottom of the clamping plate.

[0010] Further, a support plate is fixed to the upper part of the "h"-shaped frame by bolts. A roller is rotatably connected to the inner side of the support plate. The lower side wall of the roller is movably connected to the side wall of the clamping plate through a second connecting rod. A driving slide rod is movably connected to the side of the roller through a first connecting rod. The driving slide rod is slidably connected to the inner wall of the "h"-shaped frame.

[0011] On the basis of the foregoing solution: A support shaft is fixed at the center of rotation of the turntable on the base. A first limiting wheel is welded to the outer wall of the top of the support shaft. A first groove is opened on the side wall of the first limiting wheel.

[0012] A better solution in the foregoing solution is: A cam rod is in contact and cooperation with the outer wall of the first limiting wheel. The cam rod is welded to the side wall of the driving slide rod.

[0013] As a further solution of the present invention: A limiting ring is welded to the outer wall of the cam rod. A spring is buckled on one side of the limiting ring. The other side of the spring is buckled on the side wall of the "h"-shaped frame. The first groove of the first limiting wheel is located on the other side of the cutting position.

[0014] Meanwhile, the tool rest is slidably connected to the base through a support slide rod. And a sliding frame is also slidably connected to the outer wall of the top of the base. A third connecting rod is rotatably connected to the top of the sliding frame. The third connecting rod is rotatably connected to the bottom of the tool rest.

[0015] As a preferred solution of the present invention: A second limiting wheel is welded to the outer wall of the bottom of the turntable. A second groove is opened at the position of the traction switching mechanism on the second limiting wheel. And the sliding frame is in movable contact and cooperation with the outer wall of the second limiting wheel.

[0016] Meanwhile, the guiding and fixing mechanism includes a guiding frame fixed to the outer wall of the top of the base, a second guiding wheel rotatably connected to one end of the guiding frame, and an adjusting frame slidably connected to the inner wall of the guiding frame. A first guiding wheel is rotatably connected to the inner side of the adjusting frame. A stepped surface groove is formed in the inner wall of the second guiding wheel, and a stepped surface protrusion matched with the stepped surface groove is welded to the outer wall of the first guiding wheel.

[0018] The beneficial effects of the present invention are as follows: 1. In the present invention, by setting a turntable and arranging a plurality of groups of traction switching mechanisms on the outer wall of the turntable, two groups of traction switching mechanisms are used to clamp both sides of the cutting position of the metal wire to ensure the stability during cutting. On the other hand, the rotation of the turntable can also switch the working positions of the traction switching mechanisms, so as to traction the metal wire, thereby realizing multi-segment continuous automatic cutting operation and improving the cutting efficiency.

[0019] 2. In the present invention, by using the first connecting rod, the rotating roller and the second connecting rod to drive the clamping plate to lift, on the one hand, the initial included angle design between the rotating roller and the second connecting rod can be used to realize the force increasing function of clamping, increasing the clamping stability. On the other hand, when in the clamping state, the second connecting rod is in a vertical state, so it has a self-locking function, further increasing the clamping stability.

[0020] 3. In the present invention, by skillfully using the "limiting" effect and combining with the position setting of the first groove, on the one hand, the clamping and loosening of the metal wire by the traction switching mechanism can be automatically controlled according to the position where the traction switching mechanism is located. On the other hand, on the basis of automatic control, the length of the metal wire cut each time can also be controlled by controlling the rotation angle of the turntable, increasing the reliability of the device.

[0021] 4. In the present invention, by setting the tool holder as a slidable type, reliable avoidance can be provided for the rotation of the traction switching mechanism. The sliding of the tool holder is driven by the sliding frame and the third connecting rod, and the sliding frame is limited by the second limiting wheel and the second groove. The second limiting wheel rotates synchronously with the turntable, so that the support and avoidance of the tool holder can be completely automatic while being synchronized with the rotation position of the turntable, so as to achieve complete synchronous avoidance according to the position of the traction switching mechanism, increasing the reliability and synchronous linkage.

[0022] 5. In the present invention, by arranging the first guiding wheel to limit the metal wire and the second guiding wheel to be limited in cooperation with the first guiding wheel through the stepped surface groove and the stepped surface protrusion, the traction path of the metal wire can be determined, ensuring the stability of subsequent clamping. Combined with the slidability of the adjusting frame, reliable guiding of metal wires of different specifications and models can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0025] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0027] Embodiment 1: A positioning and cutting device for processing the metal surface of a notebook shell. This embodiment is designed based on a metal wire with a circular cross-section, as Figure 1-8 shown, including a base 1. A turntable 5 is rotatably connected to the top of the base 1. A plurality of traction switching mechanisms 4 are arranged on the outer side of the turntable 5. And guiding and fixing mechanisms 2 and cutting mechanisms 3 are respectively arranged at positions of the base 1 outside the traction switching mechanisms 4. And the cutting mechanism 3 is located between two adjacent traction switching mechanisms 4.

[0028] The cutting mechanism 3 includes a support frame 6 fixed to the outer wall of the top of the base 1 by bolts and a telescopic device 7 fixed to the outer wall of the top of the support frame 6 by bolts. The telescopic end of the telescopic device 7 is fixed with a cutting tool 9 by bolts. The cutting tool 9 is slidably connected to the bottom of the support frame 6 through a guide rod 8. And a tool rest 11 cooperating with the cutting tool 9 is arranged on the top of the base 1. A recess conforming to the cross-section of the metal wire is opened at the top of the tool rest 11. For a circular cross-section, the recess is semi-circular. For a rectangular cross-section, the recess corresponds to a rectangle. A tool groove 10 for avoiding the cutting tool 9 is opened on the inner wall of the tool rest 11.

[0029] A motor 13 is fixed to the outer wall of the bottom of the base 1 by bolts. The output shaft of the motor 13 is key-connected with a gear 12. The turntable 5 is meshed with the outer wall of the gear 12 through a tooth groove arranged on the side wall of its bottom.

[0030] When the device is used, the metal wire is passed through the guiding and fixing mechanism 2 and clamped by two traction switching mechanisms 4. Then, the telescopic device 7 drives the cutting tool 9 to descend. The cutting tool 9 and the tool rest 11 cooperate to cut the metal wire. After cutting, the motor 13 is started, which drives the gear 12 to rotate, thereby driving the turntable 5 to rotate. At the same time, the traction switching mechanism 4 downstream of the metal wire cutting position loosens the clamp on the metal wire. The traction switching mechanism 4 upstream rotates and continues to pull the metal wire until it reaches the position on the other side of the cutting mechanism 3. Then, another traction switching mechanism 4 clamps the upstream of the metal wire cutting position, so that the cutting mechanism 3 can be used for re-cutting.

[0031] The device is provided with a turntable 5, and multiple groups of traction switching mechanisms 4 are provided on the outer wall of the turntable 5. Two groups of traction switching mechanisms 4 are used to clamp the two sides of the metal wire cutting position to ensure stability during cutting. On the other hand, the rotation of the turntable 5 can also be used to switch the work station of the traction switching mechanism 4, so that the metal wire can be pulled, thereby realizing multi-segment continuous automatic cutting operations and improving cutting efficiency.

[0032] To solve the clamping problem; Figure 4 As shown, the traction switching mechanism 4 includes an "h"-shaped frame (42) fixed to the side wall of the turntable 5 and a clamping plate 20 slidably connected to the upper part of the "h"-shaped frame (42) through a guide rod 17, and an anti-skid pad 21 is fixed to the lower upper surface of the "h"-shaped frame (42) and the bottom outer wall of the clamping plate 20; the anti-skid pad 21 can be used to clamp the metal wire.

[0033] A support plate 16 is fixed to the top of the "h"-shaped frame (42) by bolts, and a roller 18 is rotatably connected to the inner side of the support plate 16. The lower side wall of the roller 18 is movably connected to the side wall of the clamping plate 20 through a connecting rod 2 19. The side of the roller 18 is movably connected to a driving slide bar 14 through a connecting rod 1 15, and the driving slide bar 14 is slidably connected to the inner wall of the "h"-shaped frame (42).

[0034] When the driving slide bar 14 slides, it can drive the roller 18 to rotate through the connecting rod 15, so as to drive the clamping plate 20 to descend by using the connecting rod 2 19.

[0035] This device drives the clamping plate 20 to rise and fall by utilizing the connecting rod 15, the roller 18 and the connecting rod 2 19. On the one hand, the initial angle design between the roller 18 and the connecting rod 2 19 can be utilized to realize the force-enhancing function of clamping and increase the stability of clamping. On the other hand, when in the clamping state, the connecting rod 2 19 is in a vertical state, thereby having a self-locking function, which further increases the stability of clamping.

[0036] To solve automation problems; such as Figure 6 As shown, the base 1 is fixed with a support shaft 22 at the rotation center of the turntable 5, and a limit wheel 23 is welded to the top outer wall of the support shaft 22. A groove 27 is provided on the side wall of the limit wheel 23, and a cam rod 24 is contacted and matched with the outer wall of the limit wheel 23. The cam rod 24 is welded to the side wall of the driving slide rod 14, and a limit ring 25 is welded to the outer wall of the cam rod 24. A spring 26 is buckled on one side of the limit ring 25, and the other side of the spring 26 is buckled on the side wall of the "h"-shaped frame (42).

[0037] The groove 27 of the limiting wheel 23 is located on the other side of the cutting position.

[0038] When the cam rod 24 rotates to the position where the limiting wheel 23 is not located in the groove 27, the cam rod 24 is limited by the limiting wheel 23, so that the cam rod 24 drives the driving slide bar 14 to slide to achieve clamping. When the cam rod 24 rotates to the position of the groove 27, the cam rod 24 slides under the elastic force of the spring 26, thereby driving the driving slide bar 14 to move outward to achieve loosening.

[0039] This device, by cleverly utilizing the "limiting" effect and combining it with the position setting of the groove 27, can, on the one hand, enable the clamping and loosening of the metal wire by the traction switching mechanism 4 to be automatically controlled according to the position of the traction switching mechanism 4; on the other hand, on the basis of automatic control, the length of the metal wire cut in a single time can be controlled by controlling the rotation angle of the turntable 5, thereby increasing the reliability of the device.

[0040] In order to solve the linkage problem; Figure 7 As shown, the tool holder 11 is slidably connected to the base 1 via a supporting slide rod 29, and the top outer wall of the base 1 is also slidably connected to a sliding frame 30, the top of the sliding frame 30 is rotatably connected to a connecting rod three 28, and the connecting rod three 28 is rotatably connected to the bottom of the tool holder 11.

[0041] A second limiting wheel 31 is welded to the outer wall of the bottom of the turntable 5 . The second limiting wheel 31 is provided with a second groove 32 at the position of the traction switching mechanism 4 . The sliding frame 30 is movably contacted and matched with the outer wall of the second limiting wheel 31 .

[0042] When the turntable 5 rotates, it will also drive the limiting wheel 2 31 to rotate until the traction switching mechanism 4 rotates to the position of the tool holder 11, and the sliding frame 30 cooperates with the groove 2 32, so that the tool holder 11 is lowered by gravity to avoid the traction switching mechanism 4. When the traction switching mechanism 4 rotates away from the position of the tool holder 11, the limiting wheel 2 31 cooperates with the sliding frame 30, so that the sliding frame 30 slides, thereby driving the tool holder 11 to rise through the connecting rod 3 28, which is used to support the metal wire and cooperate with cutting.

[0043] The present device can provide reliable avoidance for the rotation of the traction switching mechanism 4 by setting the tool holder 11 to be slidable, and the sliding of the tool holder 11 is driven by the sliding frame 30 and the connecting rod 3 28, and the sliding frame 30 is limited by the limiting wheel 2 31 and the groove 2 32, and the limiting wheel 2 31 rotates synchronously with the turntable 5, so that the support and avoidance of the tool holder 11 can be fully automatic, and it can also be synchronized with the rotation position of the turntable 5, so that it can achieve fully synchronized avoidance according to the position of the traction switching mechanism 4, thereby increasing the reliability of the installation and the synchronous linkage.

[0044] When this embodiment is in use, a metal wire is passed through the guiding and fixing mechanism 2 and clamped by two sets of traction switching mechanisms 4. Subsequently, the cutter 9 is driven to descend by the telescopic device 7, and the cutter 9 cooperates with the tool rest 11 to cut the metal wire. After cutting, the motor 13 is started, which drives the gear 12 to rotate, thereby driving the turntable 5 to rotate. At the same time, the traction switching mechanism 4 located downstream of the metal wire cutting position releases the clamp on the metal wire, and the traction switching mechanism 4 located upstream rotates and continues to pull the metal wire until it reaches the position on the other side of the cutting mechanism 3. Then, another set of traction switching mechanisms 4 clamps the upstream of the metal wire cutting position, so that the cutting mechanism 3 can be used for re-cutting. When the cam lever 24 rotates to a position where the first limiting wheel 23 is not located in the first groove 27, the cam lever 24 is limited by the first limiting wheel 23, so that the cam lever 24 drives the driving slide rod 14 to slide. When the driving slide rod 14 slides, it can drive the roller 18 to rotate through the first connecting rod 15, thereby driving the clamping plate 20 to descend by using the second connecting rod 19. When the cam lever 24 rotates to the position of the first groove 27, the cam lever 24 slides under the elastic force of the spring 26, thereby driving the driving slide rod 14 to move outward to achieve loosening of the clamp. In addition, when the turntable 5 rotates, it will also drive the second limiting wheel 31 to rotate. Until the traction switching mechanism 4 rotates to the position of the tool rest 11, the sliding frame 30 cooperates with the second groove 32, so that the tool rest 11 descends under the action of gravity to avoid the traction switching mechanism 4. When the traction switching mechanism 4 rotates away from the position of the tool rest 11, the second limiting wheel 31 cooperates with the sliding frame 30, so that the sliding frame 30 slides, thereby driving the tool rest 11 to rise through the third connecting rod 28 to support the metal wire and cooperate with the cutting.

[0045] Embodiment 2: A positioning and cutting device for processing the metal surface of a notebook shell, as Figure 8 shown. To solve the guiding problem; the following improvements are made on the basis of Embodiment 1: The guiding and fixing mechanism 2 includes a guiding frame 33 fixed to the outer wall of the top of the base 1, a second guiding wheel 35 rotatably connected to one end of the guiding frame 33, and an adjusting frame 38 slidably connected to the inner wall of the guiding frame 33. A first guiding wheel 34 is rotatably connected to the inner side of the adjusting frame 38. A stepped surface groove 36 is formed in the inner wall of the second guiding wheel 35, and a stepped surface protrusion 37 cooperating with the stepped surface groove 36 is welded to the outer wall of the first guiding wheel 34.

[0046] A screw rod 39 is threadedly connected to the inner wall of the guiding frame 33. The screw rod 39 is rotatably connected to the side wall of the adjusting frame 38. A knob 40 is fixed to the end of the adjusting frame 38 by a bolt. A locknut 41 is also threadedly connected to the outer wall of the screw rod 39.

[0047] When this embodiment is in use, the metal wire can be passed through the ladder surface groove 36. The opening position of the ladder surface groove 36 is limited by the ladder surface protrusion 37 to limit the metal wire. And when dealing with metal wires of different models and specifications, the knob 40 can be rotated, which can drive the screw 39 to rotate. Thus, due to the thread action, the screw 39 moves axially, driving the adjusting frame 38 to move, thereby adjusting the relative position between the first guide wheel 34 and the second guide wheel 35. After the adjustment is completed, the locknut 41 can be rotated and tightened until it fits against the guide frame 33 to achieve locking.

[0048] In this device, the first guide wheel 34 and the first guide wheel 34 are used to limit the metal wire, and the second guide wheel 35 and the first guide wheel 34 are limited by the cooperation of the ladder surface groove 36 and the ladder surface protrusion 37. Thus, the traction path of the metal wire can be determined to ensure the stability of subsequent clamping. Combined with the slidability of the adjusting frame 38, reliable guidance for metal wires of different specifications can be achieved.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
