Description

Technical Field

[0001] This application relates to the field of laser knife template assembly and disassembly tools, and in particular to an intelligent knife puller. Background Technology

[0002] A laser die is a die for cutting shapes. It is used by stamping and its structure usually consists of a base plate and a steel blade. The steel blade is the cutting tool of the laser die and can also be called a laser die template. When disassembling the laser die template, a tool puller is used. Because the tool puller has a pliers-like structure, it is also called a tool puller.

[0003] In related technologies, such as CN204397825, a vertically upward knife-pulling pliers includes a pliers body 1, which can be composed of two panels with a groove in the middle, forming an inner cavity 2. A movable block 7, capable of vertical displacement relative to the pliers body, is provided at the lower end of the inner cavity 2. Two clamping plates forming a clamp 8 are mounted on the movable block 7 via a rotating shaft 10. The two clamping plates of the clamp 8 rotate along their respective rotating shafts to clamp and release the clamp 8. A slider 6 is connected to the upper end of the clamp 8. The inner sides of the upper parts of the two clamping plates are respectively provided with arc-shaped grooves of the same shape. A symmetrically shaped cam block 9 is provided at the lower end of the slider 6, with its two sides located within the two arc-shaped grooves. The two clamping plates and the two sliding grooves 5 are symmetrically arranged along the same vertical line. The slider is moved vertically by operating an operating component, thereby clamping or releasing the clamp. An operating component is connected to the upper end of the slider 6. The operating component includes a pull rod 4 connected to the upper end of the slider 6 via a pin, and a handle 3 connected to the upper end of the pull rod 4 via a pin. The lower end of the handle 3 is connected to the clamp body 1 via a rotating shaft, and the upper part of the handle 3 protrudes outside the clamp body 1.

[0004] Regarding the aforementioned technologies, there is a drawback: when using the puller pliers, the operator holds one hand in the groove on the outside of the pliers body and the other hand on the handle. At this time, the handle and the hand holding the pliers body are on the same plane, while the clamping surface of the pliers is perpendicular to the plane where the handle is located. Therefore, when pulling the laser knife template from different positions, the operator needs to adjust their own position, which makes the disassembly of the laser knife template quite cumbersome. Summary of the Invention

[0005] To make the disassembly of the laser knife template simpler and more convenient, this application provides an intelligent knife puller.

[0006] The intelligent knife puller provided in this application adopts the following technical solution:

[0007] A smart knife puller, comprising:

[0008] The clamp body shell is divided into a lower knife-pulling part and an upper gripping part that are coaxially rotatably connected. The outer wall of the upper gripping part is provided with a gripping groove, and the clamp body shell is coaxially provided with a receiving channel.

[0009] A clamping plate mounting base is slidably disposed in the receiving channel of the lower blade puller;

[0010] Two clips are provided, and the two clips are slidably disposed on the clip mounting base in a manner that allows them to move closer to or further away from each other;

[0011] The knife-drawing slider is slidably disposed in the receiving channel of the upper grip;

[0012] A handle-type operating component is connected to the knife-drawing slider, wherein the swing plane of the handle in the handle-type operating component is parallel to the plane of the hand at the grip groove;

[0013] The compatible connecting rod has one end coaxially rotatably connected to the knife-pulling slider, and the other end is provided with a clamping transmission component. The clamping transmission component is connected to the two clamping plates and is used to transform the sliding of the knife-pulling slider into the two clamping plates moving closer or further apart.

[0014] By adopting the above technical solution, since the lower blade-pulling part and the upper gripping part can slide relative to each other, and the connecting rod and the blade-pulling slider can slide relative to each other, when the two clamping plates hold the laser blade template at different positions, the upper gripping part can be rotated to change the angle relationship between the swing plane where the handle is located and the clamping surface of the two clamping plates. Therefore, the operator can continue to use the blade-pulling device without changing the position. At the same time, the swing plane where the handle is located is still parallel to the plane where the hand is located at the grip groove, so the disassembly work performed by the operator using the blade-pulling device can be made simpler.

[0015] Preferably, a lower splicing ring, an upper splicing ring, a splicing bearing, and a locking member are provided between the lower blade-pulling part and the upper gripping part. The lower splicing ring is disposed on the end face of the lower blade-pulling part near the upper gripping part; the upper splicing ring is disposed on the end face of the upper gripping part near the lower blade-pulling part, and the upper splicing ring is sleeved on the outer side of the lower splicing ring; the splicing bearing is disposed at the sleeve position between the lower splicing ring and the upper splicing ring; the locking member is connected to the lower blade-pulling part and the upper gripping part respectively, and is used to restrict the rotation between the upper gripping part and the lower blade-pulling part.

[0016] By adopting the above technical solution, a free rotational connection between the lower blade-drawing part and the upper gripping part can be achieved. Therefore, the relative posture between the lower blade-drawing part and the upper gripping part can be freely changed. At the same time, after adjustment, the relative rotation between the lower blade-drawing part and the upper gripping part can be restricted by the locking part, thereby maintaining the normal use of the blade drawer.

[0017] Preferably, the locking member includes a locking tube and a locking block. The locking tube is slidably sleeved on the outer wall of the upper grip portion. The end face of the locking tube near the lower knife-pulling portion is provided with a plurality of locking grooves, which are evenly distributed around the center line of the locking tube. The locking block is disposed on the outer wall of the lower knife-pulling portion, and one locking block is inserted into one of the locking grooves.

[0018] By adopting the above technical solution, when it is necessary to change the relative posture between the lower blade-pulling part and the upper gripping part, the locking tube can be moved upward to make the locking block leave the locking groove. After the relative posture between the lower blade-pulling part and the upper gripping part is adjusted, the locking tube can be moved downward to make the locking block embed into the locking groove, thereby achieving the purpose of restricting the relative rotation between the lower blade-pulling part and the upper gripping part.

[0019] Preferably, the clamping piece has a transmission sliding hole at one end near the blade-pulling slider. The transmission sliding hole is oval and extends along the orthogonal directions of the two movement directions of the blade-pulling slider and the clamping piece. The clamping transmission component includes a transmission rod and a clamping spring. The transmission rod is disposed on the compatible connecting rod, and there are two transmission rods, which are slidably inserted into the transmission sliding hole. The clamping spring is connected to the two clamping pieces. When the two clamping pieces clamp the blade template, the clamping spring applies a pulling force to the two clamping pieces in a mutually closer direction.

[0020] By adopting the above technical solution, on the one hand, the up-and-down sliding of the knife-pulling slider can be transformed into the clamping and releasing between two clamping plates through the cooperation between the transmission sliding hole and the transmission rod, thus making the structure of the entire knife-pulling device simpler; on the other hand, the clamping spring can also provide pre-clamping force to the two clamping plates, so that the two clamping plates are less likely to loosen due to the operator accidentally releasing the handle-type operating part during the process of pulling out the laser knife template, so that the operator can maintain the smoothness of the knife-pulling operation even when adopting the segmented knife-pulling method.

[0021] Preferably, the handle-type operating component includes a handle and a lever. One end of the handle is rotatably connected to the receiving channel of the upper grip, and the other end is for the operator to hold. One end of the lever is rotatably connected to the handle, and the connection point between the lever and the handle is located on the side away from the operator's grip at the connection point between the handle and the upper grip. The other end of the lever is hinged to the knife-pulling slider. The knife-pulling slider is connected to an external transmission block, and the end of the external transmission block away from the compatible connecting rod extends outside the upper grip. The outer wall of the upper grip is provided with a force-applying block and a force-applying spring, and the force-applying block is located above the external transmission block. One end of the force-applying spring is connected to the external transmission block, and the other end is connected to the force-applying block, for applying a downward buffering force to the compatible connecting rod after the laser knife template is pulled out.

[0022] By adopting the above technical solution, since the operator needs to press down the handle with all their might during the knife-pulling process, the resistance that prevents the handle from pressing down will disappear after the laser knife template is pulled out. At this time, the force spring can apply a downward buffering force to the knife-pulling slider, so that the hand is less likely to slip off the handle due to the rapid disappearance of resistance, thus enabling the operator to operate the knife-pulling device more safely.

[0023] Preferably, the force-applying block is slidably disposed on the outer wall of the upper grip, and the movement direction of the force-applying block is parallel to the movement direction of the blade-pulling slider; the outer wall of the upper grip is also provided with an adjustment drive assembly, which is connected to the force-applying block and is used to apply an upward pre-pulling force to the compatible connecting rod through the force-applying spring after the clamping plate holds the laser blade template.

[0024] By adopting the above technical solution, when processing some precision laser scalpel templates, the pull-out slider is first moved upward to allow the two clamping plates to hold the laser scalpel template. Then, by adjusting the drive component, the force application block is moved away from the external transmission block so that the force application spring transmits the upward pre-pulling force to the pull-out slider. After the pre-pulling force and the pull-out force of the laser scalpel template reach a predetermined ratio, the pull-out slider is moved upward again to pull out the laser scalpel template. In summary, during the above process, the force on the laser scalpel template gradually increases during the pull-out process, thereby reducing the damage to the laser scalpel template during the pull-out process.

[0025] Preferably, the adjustment drive assembly includes an adjustment screw, which is rotatably connected to the outer wall of the upper grip, and one end of the adjustment screw is threaded through the force application block.

[0026] By adopting the above technical solution, the position of the force-applying block can be changed by adjusting the rotation of the lead screw to make the force-applying block slide, and the position stability of the force-applying block can be maintained when the lead screw does not rotate.

[0027] Preferably, the adjustment drive assembly further includes a driven worm gear and a driving worm. The driven worm gear is sleeved on the adjustment screw, and the driving worm is rotatably connected to the outer wall of the upper gripping part, and the driving worm meshes with the driven worm gear.

[0028] By adopting the above technical solution, on the one hand, the cooperation between the active worm and the driven worm wheel can drive the adjusting screw to rotate more effortlessly; on the other hand, the self-locking property between the active worm and the driven worm wheel can also be used to improve the positional stability of the force-applying block.

[0029] Preferably, the adjustment drive component further includes:

[0030] The driven gear is sleeved on the driving worm gear;

[0031] An independent loading plate is detachably mounted on the outer wall of the upper grip.

[0032] The active rack is slidably mounted on the independent loading plate, and the active rack meshes with the driven gear;

[0033] The operating wheel is rotatably mounted on the independent loading plate;

[0034] A pulley block is installed on the independent loading plate. The movable pulley of the pulley block is connected to the active rack. The rope extending from the fixed pulley in the pulley block is wound and fixed on the operating wheel.

[0035] By adopting the above technical solution, on the one hand, the operating wheel can pull the active rack to slide more effortlessly through the pulley system, thus driving the force application block to move more effortlessly, making it easier for workers to use the knife extractor; on the other hand, when it is not necessary to disassemble the precision laser knife template, the independent loading plate can also be removed, so that the configuration of the knife extractor can be changed according to different situations, thereby helping to improve the practicality of the knife extractor.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. Because the lower blade-pulling part and the upper gripping part can slide relative to each other, and the connecting rod and the blade-pulling slider can also slide relative to each other, the upper gripping part can be rotated to change the angle between the swing plane of the handle and the clamping surface of the two clamping pieces when the two clamping pieces hold the laser blade template at different positions. Therefore, the blade-pulling device can continue to be used without changing the operator's position. At the same time, the swing plane of the handle is still parallel to the plane of the hand at the grip groove, making the disassembly work performed by the operator through the blade-pulling device simpler.

[0038] 2. When processing precision laser scalpel templates, the pull-out slider is first moved upwards to clamp the laser scalpel template with two clamping plates. Then, the drive assembly is adjusted to move the force application block away from the external transmission block, so that the force application spring transmits an upward pre-pulling force to the pull-out slider. Once the pre-pulling force and the pull-out force of the laser scalpel template reach a predetermined ratio, the pull-out slider is moved upwards again to pull out the laser scalpel template. In summary, during the above process, the force on the laser scalpel template gradually increases, thereby reducing damage to the laser scalpel template during the pull-out process.

[0043] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0044] This application discloses an intelligent knife puller. (Refer to...) Figure 1 and Figure 2The intelligent knife extractor includes a clamp housing 1, a clamp mounting base 2, a clamp 3, a knife-pulling slider 4, a handle-type operating component 5, and a compatible connecting rod 6. Specifically, the clamp housing 1 is divided into a lower knife-pulling part 11 and an upper gripping part 12, which are coaxially rotatably connected from bottom to top. The outer wall of the upper gripping part 12 is provided with a gripping groove 13 for the operator's hand to hold. At the same time, the clamp housing 1 also has an integrally formed cylindrical receiving channel 14, which connects the lower knife-pulling part 11 and the upper gripping part 12. The rotating shafts between them are coaxially arranged; the clamping plate mounting base 2 is slidably arranged in the receiving channel 14 of the lower blade-pulling part 11, and the clamping plate 3 mounting bracket moves along the axial direction of the receiving channel 14. The clamping plate mounting base 2 is located on the end of the lower blade-pulling part 11 away from the upper gripping part 12; there are two clamping plates 3, and the two clamping plates 3 are slidably arranged on the clamping plate mounting base 2 in a manner that is close to or far away from each other. The sliding direction of the clamping plates 3 is perpendicular to the axial direction of the receiving channel 14, so as to realize the clamping and releasing of the laser blade template.

[0045] Reference Figure 1 and Figure 2 The knife-drawing slider 4 is slidably disposed in the receiving channel 14 of the upper grip 12, and the movement direction of the knife-drawing slider 4 is parallel to the axis of the receiving channel 14. The handle-type operating member 5 is connected to the knife-drawing slider 4. The handle-type operating member 5 can move the knife-drawing slider 4 up or down. At the same time, the swing plane of the handle 51 in the handle-type operating member 5 is parallel to the plane of the hand at the grip groove 13, so that the knife-drawing device can adapt to the posture of the operator's two hands. The compatible connecting rod 6 is cylindrical in shape. One end of the compatible connecting rod 6 is coaxially rotatably connected to the knife-drawing slider 4 so that the compatible connecting rod 6 and the knife-drawing slider 4 can rotate relative to each other. The other end is provided with a clamping transmission member 61, which is connected to two clamping plates 3 to convert the sliding of the knife-drawing slider 4 into the approaching or moving away of the two clamping plates 3, thereby realizing the basic knife-drawing process.

[0046] Reference Figure 1 and Figure 2 In summary, firstly, because the lower blade-pulling part 11 and the upper gripping part 12 can slide relative to each other, and secondly, because the connecting rod 6 and the blade-pulling slider 4 can slide relative to each other, when the two clamping plates 3 hold the laser blade template at different positions, the upper gripping part 12 can be rotated to change the angle between the swing plane where the handle 51 is located and the clamping surfaces of the two clamping plates 3. Therefore, the operator can continue to use the blade-pulling device without changing the position, making the disassembly work performed by the operator through the blade-pulling device simpler.

[0047] Reference Figure 1 and Figure 2To ensure smoother rotation between the lower pull-out part 11 and the upper grip part 12, and to stabilize the posture of the clamp housing 1 when using the pull-out tool, the specific connection between the lower pull-out part 11 and the upper grip part 12 is as follows: a lower splicing ring 15, an upper splicing ring 16, a splicing bearing 17, and a locking member 18 are provided between the lower pull-out part 11 and the upper grip part 12. Specifically, the lower splicing ring 15 is integrally formed on the lower pull-out part 11 near the upper grip part 12. On the end face of part 2, the lower splicing ring 15 is coaxially arranged with the receiving channel 14; the upper splicing ring 16 is also integrally formed on the end face of the upper grip part 12 near the lower blade-pulling part 11, the upper splicing ring 16 is coaxially arranged with the receiving channel 14, and the upper splicing ring 16 is coaxially sleeved on the outer side of the lower splicing ring 15; the splicing bearing 17 is arranged at the sleeve between the lower splicing ring 15 and the upper splicing ring 16, thereby realizing free rotation between the lower blade-pulling part 11 and the upper grip part 12.

[0048] Reference Figure 1 and Figure 2 The locking component 18 includes a locking tube 181 and a locking block 182. The locking tube 181 is in the shape of a round tube and is coaxially slidably sleeved on the outer wall of the upper grip part 12. Multiple locking grooves 1811 are integrally formed on the end face of the locking tube 181 near the lower knife-pulling part 11. The multiple locking grooves 1811 are evenly distributed around the center line of the locking tube 181. The locking block 182 is fixedly connected to the outer wall of the lower knife-pulling part 11. Multiple locking blocks 182 are also evenly distributed around the center line of the locking tube 181. At the same time, one locking block 182 is inserted into one of the locking grooves 1811. Therefore, the relative rotation between the lower knife-pulling part 11 and the upper grip part 12 can be restricted or released through the cooperation between the locking block 182 and the locking groove 1811.

[0049] Reference Figure 1 and Figure 2 To make it easier for staff to use the knife drawer, the handle-type operating component 5 includes a handle 51 and a lever 52. Specifically, one end of the handle 51 is rotatably connected to the receiving channel 14 of the upper grip 12, and the axis of the rotatable connection intersects with the axis of the receiving channel 14. The other end of the handle 51 is for staff to hold. One end of the lever 52 is rotatably connected to the handle 51, and the connection point between the lever 52 and the handle 51 is located on the side away from the connection point between the handle 51 and the upper grip 12. The other end of the lever 52 is hinged to the knife draw slider 4. Therefore, pressing down on the handle 51 will cause the knife draw slider 4 to move upward, and moving upward on the handle 51 will cause the knife draw slider 4 to move downward. This makes the knife drawer more suitable for the posture of both hands, thereby improving the ease of use of the knife drawer.

[0050] Reference Figure 1 and Figure 2During the knife-drawing process, the handle 51 needs to be continuously pressed down. Therefore, to improve the clamping stability of the clamping plate 3, the following settings are provided: First, a transmission sliding hole 31 is provided at the end of the clamping plate 3 near the knife-drawing slider 4. The transmission sliding hole 31 is oval in shape and extends along the orthogonal direction between the movement direction of the knife-drawing slider 4 and the movement direction of the clamping plate 3, forming the basic structure for external components to drive the two clamping plates 3 to move closer or further apart. Second, the clamping transmission component 61 includes a transmission rod 611 and a clamping spring 612. The transmission rod 611 is cylindrical in shape and is connected to... Two transmission rods 611 are provided on the end of the compatible connecting rod 6 away from the blade-pulling slider 4. The two transmission rods 611 are respectively slidably inserted into the transmission sliding hole 31 so that the movement of the blade-pulling slider 4 can realize the approach or distance of the two clamping plates 3. The two ends of the clamping spring 612 are respectively connected to the two clamping plates 3. When the two clamping plates 3 clamp the blade template, the clamping spring 612 will apply a pulling force to the two clamping plates 3 in the direction of mutual approach. Therefore, when the operator accidentally releases the handle 51, the two clamping plates 3 will not release the blade template. Thus, the operator can maintain the smoothness of the blade-pulling operation even when using the segmented blade-pulling method.

[0051] Reference Figure 1 and Figure 3 Because the resistance on the handle 51 will disappear quickly after the laser blade template is pulled out, the following settings are made to improve the safety of using the puller: First, the puller slider 4 is fixedly connected to an external transmission block 41, with one end of the external transmission block 41 extending out of the upper grip 12 away from the puller slider 4. Since the puller slider 4 moves up and down, the upper grip 12 has a hole-like structure at the point where the external transmission block 41 passes through to avoid it. Second, the outer wall of the upper grip 12 is provided with a force-applying block 7 and a force-applying spring 71. The force-applying block 7 is located above the external transmission block 41. One end of the force-applying spring 71 is connected to the external transmission block 41, and the other end is connected to the force-applying block 7. Therefore, after the laser blade template is pulled out, a downward buffering force can be applied to the compatible connecting rod 6.

[0052] Reference Figure 1 and Figure 3When removing a precision laser scalpel template, to minimize damage, the removal force on the template needs to be more uniform. Therefore, the following configuration is implemented: First, the force-applying block 7 is slidably mounted on the outer wall of the upper gripping part 12. The movement direction of the force-applying block 7 is parallel to the movement direction of the removal slider 4, so that the force-applying spring 71 is in a stretched state, applying an upward pre-removal force to the compatible connecting rod 6. Second, the outer wall of the upper gripping part 12 is also equipped with an adjustment drive assembly 8. The adjustment drive assembly 8 is used to change the distance between the force-applying block 7 and the external transmission block 41. Specifically, the adjustment drive assembly 8 includes... The adjustment screw 81, driven worm gear 82, and driving worm 83 are configured. The adjustment screw 81 is rotatably connected to the outer wall of the upper gripping part 12, and one end of the adjustment screw 81 is threaded through the force application block 7. The driven worm gear 82 is coaxially sleeved on the adjustment screw 81, and the driving worm 83 is rotatably connected to the outer wall of the upper gripping part 12. The driving worm 83 meshes with the driven worm gear 82. Therefore, under the transmission characteristics of the adjustment screw 81 and the self-locking effect of the driving worm 83 and the driven worm gear 82, the positional stability of the force application block 7 can be improved, the adjustment accuracy of the force application block 7 can be improved, and the adjustment of the force application block 7 can be made more stable.

[0053] Reference Figure 1 and Figure 3 To further simplify the adjustment of the position of the force-applying block 7 and enable changes in the configuration of the drawarm, the adjustment drive assembly 8 also includes a driven gear 84, an independent loading plate 85, a drive rack 86, an operating wheel 87, and a pulley assembly 88. The driven gear 84 is coaxially mounted on the drive worm 83, and the driven gear 84 and the drive worm 83 are connected by a common flat key, thus the driven gear 84 serves as an intermediary element for external power input. The independent loading plate 85 is detachably mounted on the outer wall of the upper grip 12, serving as a carrier for the components required to change the drawarm configuration, while the driven gear 84 is rotatably connected to the independent loading plate 85. The drive rack 87 slides... The active rack 86 is mounted on the independent loading plate 85, and its sliding direction is parallel to the movement direction of the force-applying block 7. The active rack 86 meshes with the driven gear 84. The operating wheel 87 is rotatably mounted on the independent loading plate 85 as a direct operating element for the operator. The pulley block 88 is mounted on the independent loading plate 85, wherein the movable pulley of the pulley block 88 is connected to the active rack 86, and the movable pulley moves with the active rack 86. The rope extending from the fixed pulley in the pulley block 88 is wound and fixed on the operating wheel 87. Therefore, the operating wheel 87 can pull the active rack 86 more effortlessly through the pulley block 88, thereby making it easier to adjust the force-applying block 7.

[0054] In this embodiment, the independent loading plate 85 can also be removed, so the configuration of the knife puller can be changed according to different situations, thereby helping to improve the practicality of the knife puller.

[0055] The implementation principle of the intelligent knife puller in this application embodiment is as follows: Firstly, because the lower knife pulling part 11 and the upper gripping part 12 can slide relative to each other, and secondly, because the connecting rod 6 and the knife pulling slider 4 can slide relative to each other, when the two clamping plates 3 hold the laser knife template at different positions, the upper gripping part 12 can be rotated to change the angle relationship between the swing plane where the handle 51 is located and the clamping surface of the two clamping plates 3. Therefore, the operator can continue to use the knife puller without changing the position, so that the disassembly work performed by the operator through the knife puller can be simpler.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
