Description

Technical Field

[0004] However, it is found in the punching process that the existing clamping device simply fits and fixes the side of the handle, and there will be a downward extrusion force during the punching process to push the handle, causing the handle to turn and shift, thus reducing the punching accuracy and further reducing the production quality of the handle.

[0005] If the shape of the handle is relatively curved and there are complex patterns engraved on the surface, then the existing clamping device is not suitable for clamping and fixing the curved handle; at the same time, during the punching process, due to the uneven surface of the handle, the drill bit will shift on the uneven surface, thus reducing the punching accuracy and being unfavorable to the production efficiency of the handle; for this reason, a positioning and punching device for door lock processing and its working method are proposed to improve the existing problems.

[0016] A positioning and punching method for door lock processing, using the positioning and punching device for door lock processing as described above, includes the following steps: S1.

Under the condition of clamping by the fixing component, the pre-positioning component strikes and positions the surface of the bent handle to be punched. S3. When punching, the punching motor is activated to drive the worm to rotate.

At the same time, this punching component can also achieve the purpose of punching in a small space, thereby improving the practicability.

[0018] (2) Through the design of the pre-positioning component, vertical positioning is performed on various surfaces of the handle to be punched, so that the striking member always remains perpendicular to the surface to be punched. When the punching component punches, only the hole after striking needs to clamp and position the punching component, thereby realizing the pre-positioning before punching, avoiding the situation that the surface of the handle is uneven, resulting in the deviation of the drill bit on the uneven surface, and further improving the punching accuracy and the production efficiency of the handle.

[0032] It should be noted that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0033] Please refer to Figures 1-12 , the present invention provides the following technical solutions: Example 1, refer to Figures 1-12 , a positioning and punching device for door lock processing, including a fixing component 1, a punching component 2 is arranged on one side of the fixing component 1, and a pre-positioning component 3 is arranged at one end of the punching component 2.

[0034] Among them, the function of the fixing component 1 is to clamp and fix both conventional handles and bent handles, avoiding the problem that the existing clamping devices simply fit and fix the side of the handle, and there will be a downward extrusion force during the punching process to push the handle, causing the handle to turn and shift, thereby improving the punching accuracy and further improving the production quality of the handle.

[0035] The function of the punching component 2 is to avoid the interference of the ordinary punching mechanism on the bent handle. Compared with the existing punching mechanism that moves up and down directly for punching, the punching component 2 in the present invention can enter the position to be punched from the side and move the drive that occupies a large area in the prior art away from the bent handle, thereby avoiding the problem that the convex surface of the bent handle is directly above the position to be drilled, resulting in the interference of the bent handle with the punching mechanism for punching, thus ensuring the smooth progress of punching. At the same time, the punching component 2 can also achieve the purpose of punching in a small space, thereby improving the practicability.

[0036] The function of the pre-positioning component 3 is to vertically position various surfaces to be punched of the handle, so that the striking member 38 always remains perpendicular to the surface to be punched. When the punching component 2 performs punching, it only needs to make the holes after punching clamp and position the punching component 2, thus realizing the pre-positioning before punching, avoiding the situation that the surface of the handle is uneven, resulting in the deviation of the drill bit on the uneven surface, thereby improving the punching accuracy and further improving the production efficiency of the handle.

[0037] Refer to Figures 6-8 , specifically, the punching component 2 includes a punching motor 21, a worm 22 arranged at the output end of the punching motor 21, a worm gear 23 meshed and driven with the worm 22, a connecting block 24 arranged on one side of the worm gear 23, a reciprocating plate 25 rotatably connected to one end of the connecting block 24, a reciprocating block 26 rotatably connected to the end of the reciprocating plate 25 far from the connecting block 24, a chain belt 27 arranged at the end of the reciprocating block 26 far from the reciprocating plate 25, and a drilling member 28 arranged on one side of the chain belt 27.

[0038] Among them, when punching, the punching motor 21 is started to drive the worm 22 to rotate. Since the worm 22 is meshed and driven with the worm gear 23, the worm gear 23 will also rotate, and drive the connecting block 24 to rotate synchronously, so that the connecting block 24 drives the reciprocating plate 25 to be pulled back or pushed out. The reciprocating block 26 displaces along with the reciprocating plate 25, and drives the chain belt 27 to be pulled back or pushed out synchronously, so that the chain belt 27 drives the drilling member 28 to start and punch the side wall surface of the bent handle.

[0039] Refer to Figures 9-12 , specifically, the pre-positioning component 3 includes an extension plate 31, a first motor 32 arranged at the bottom of the extension plate 31, a first gear 321 arranged at the output end of the first motor 32, a second motor 33 arranged on one side of the first motor 32, a second gear 331 arranged at the output end of the second motor 33, a third motor 34 arranged on the side of the second motor 33 far from the first motor 32, a third gear 341 arranged at the output end of the third motor 34, a fixing column 35 arranged in the middle below the extension plate 31, an adjusting member 36 sleeved on the fixing column 35, an adjusting plate 37 arranged in the adjusting member 36, and a striking member 38 arranged below the adjusting plate 37.

[0040] Among them, when the surface to be punched of the handle is an inclined surface, at this time, it is necessary to perform pre-positioning strikes on the position to be punched, so that pre-positioning holes appear on the surface to be punched.

[0041] When the hole for pre-positioning strike is within the rotation range of the first auxiliary rod 364, the first motor 32 starts, driving the first gear 321 to rotate, so that the first auxiliary gear 361 rotates synchronously, and drives the first auxiliary column 362 and the first auxiliary bar 363 to rotate synchronously, causing the first auxiliary bar 363 to drive the first auxiliary rod 364 to rotate and shift. At this time, the first auxiliary rod 364 will pull the adjusting plate 37 to perform an angular flip in the direction of the first auxiliary rod 364, so that the striking member 38 flips synchronously, making the striking member 38 always perpendicular to the surface to be drilled. When the drilling assembly 2 drills a hole, it only needs the hole after striking to clamp and position the drilling assembly 2, thus realizing the pre-positioning before drilling, avoiding the situation that the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface, thereby improving the drilling accuracy and further improving the production efficiency of the handle.

[0042] When the hole for pre-positioning strike is within the rotation range of the second auxiliary rod 368, the second motor 33 starts, driving the second gear 331 to rotate, so that the second auxiliary gear 365 rotates synchronously, and drives the second auxiliary column 366 and the second auxiliary bar 367 to rotate synchronously, causing the second auxiliary bar 367 to drive the second auxiliary rod 368 to rotate and shift. At this time, the second auxiliary rod 368 will pull the adjusting plate 37 to perform an angular flip in the direction of the second auxiliary rod 368, so that the striking member 38 flips synchronously, making the striking member 38 always perpendicular to the surface to be drilled. When the drilling assembly 2 drills a hole, it only needs the hole after striking to clamp and position the drilling assembly 2, thus realizing the pre-positioning before drilling, avoiding the situation that the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface, thereby improving the drilling accuracy and further improving the production efficiency of the handle.

[0043] When the hole for pre-positioning strike is within the rotation range of the third auxiliary rod 3611, the third motor 34 starts, driving the third gear 341 to rotate, so that the third auxiliary gear 369 rotates synchronously, and drives the third auxiliary bar 3610 to rotate synchronously, causing the third auxiliary bar 3610 to drive the third auxiliary rod 3611 to rotate and shift. At this time, the third auxiliary rod 3611 will pull the adjusting plate 37 to perform an angular flip in the direction of the third auxiliary rod 3611, so that the striking member 38 flips synchronously, making the striking member 38 always perpendicular to the surface to be drilled. When the drilling assembly 2 drills a hole, it only needs the hole after striking to clamp and position the drilling assembly 2, thus realizing the pre-positioning before drilling, avoiding the situation that the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface, thereby improving the drilling accuracy and further improving the production efficiency of the handle.

[0044] When the surface of the handle to be drilled is a horizontal surface, the first motor 32, the second motor 33, and the third motor 34 are started simultaneously at this time, and drive the corresponding first gear 321, second gear 331, and third gear 341 to rotate, so that the adjusting member 36 can be rotated horizontally as a whole at the same time, and the adjusting plate 37 rotates accordingly, so that the striking member 38 can be rotated above the position to be pre-positioned and struck.

[0045] Finally, by rotating the corresponding auxiliary rod, the flipping angle of the striking member 38 is adjusted, so that the striking member 38 is always perpendicular to the surface to be drilled, achieving precise striking.

[0046] Refer to Figures 1-5 , further, the fixing assembly 1 includes a workbench 11, a fixing seat 12 arranged on the top of the workbench 11, a telescopic cylinder 13 arranged at one end of the fixing seat 12, a telescopic block 14 arranged at the telescopic end of the telescopic cylinder 13, and an adaptive member 15 symmetrically arranged in the fixing seat 12 in the axial direction M; the fixing seat 12 is U-shaped, a guiding groove 121 is opened at the inner bottom of the fixing seat 12, a guiding block 122 slides in the guiding groove 121, the top of the guiding block 122 is connected to the bottom of the telescopic block 14, and the telescopic end of the telescopic cylinder 13 penetrates through the side wall of one end of the fixing seat 12 and is connected to the telescopic block 14.

[0047] Refer to Figures 1-5 , furthermore, one of the adaptive members 15 is connected to the inner side wall of the fixing seat 12, and the other adaptive member 15 is connected to the side wall of the telescopic block 14 away from the telescopic cylinder 13; the adaptive member 15 includes an adaptive block 151, adaptive columns 152 uniformly arranged on one side of the adaptive block 151, and a spring 153 arranged at one end of the adaptive column 152; through holes 154 are uniformly opened on the side wall of the adaptive block 151, the adaptive columns 152 can be inserted into the corresponding through holes 154 in a matching manner, one end of the spring 153 away from the adaptive column 152 is connected to the inner wall of the corresponding through hole 154, and the adaptive columns 152 are distributed oppositely.

[0048] Among them, before drilling the side wall of the handle, first place the handle vertically in the fixing seat 12, and then start the telescopic cylinder 13, and its telescopic end pushes the telescopic block 14 to extend. In this process, on the one hand, the telescopic block 14 will drive the guiding block 122 to slide in the guiding groove 121, achieving the purpose of guiding; on the other hand, the telescopic block 14 will drive the corresponding adaptive member 15 to approach the side of the handle and push the handle closer to the other stationary adaptive member 15 until the two adaptive members 15 clamp the handle, thus achieving the purpose of clamping the handle.

[0049] If it is a curved handle, during the process of clamping the curved handle by the two adaptive members 15, several adaptive columns 152 will retract into the corresponding through holes 154 due to the uneven side wall of the curved handle, and the corresponding springs 153 will also be compressed and deformed. At this time, the lengths of the several adaptive columns 152 extending out of the through holes 154 will be different, thus achieving the purpose of clamping and fixing the curved handle, avoiding the problem that the existing clamping device simply fits and fixes the side surface of the handle, and there will be a downward extrusion force during the drilling process to push the handle, causing the handle to turn and shift, thereby improving the drilling accuracy and further improving the production quality of the handle.

[0050] Embodiment 2, refer to Figures 6-8 , further, in this embodiment, specifically: on the top of the workbench 11, slide rails 16 are symmetrically arranged in the radial N direction. Electric sliders 161 are slidably connected to the slide rails 16, and a slide plate 162 is arranged between the electric sliders 161; a horizontal electric linear guide rail 17 is arranged on the top of the slide plate 162, a vertical electric linear guide rail 18 is arranged on one side of the horizontal electric linear guide rail 17, and a carrier plate 19 is arranged on the side of the vertical electric linear guide rail 18 away from the horizontal electric linear guide rail 17.

[0051] Among them, before drilling holes in the side wall surface of the curved handle, it is necessary to first start the electric slider 161, so that the electric slider 161 slides on the slide rail 16 and drives the slide plate 162 to move synchronously. Finally, the drilling assembly 2 and the pre-positioning assembly 3 are displaced synchronously, enter the position to be drilled from the side, and move the drive that occupies a large area in the prior art away from the curved handle, thereby avoiding the problem that the convex surface of the curved handle is located directly above the position to be drilled, resulting in interference of the curved handle with the drilling mechanism during drilling, thus ensuring the smooth progress of drilling. At the same time, the drilling assembly 2 of the present invention can also achieve the purpose of drilling in a small space, thereby improving the practicability.

[0052] By starting the horizontal electric linear guide rail 17, the drilling assembly 2 and the pre-positioning assembly 3 can be driven to perform horizontal displacement. Specifically: first start the pre-positioning assembly 3 to strike and position the surface of the handle to be drilled, then start the horizontal electric linear guide rail 17 to perform horizontal displacement on the drilling assembly 2 and the pre-positioning assembly 3, so that the pre-positioning assembly 3 is located directly above the hole after strike positioning, and finally the drilling assembly 2 is started to perform drilling operations on the hole after strike positioning.

[0053] By starting the vertical electric linear guide rail 18, the drilling assembly 2 can be driven to descend and approach the side wall surface of the handle for drilling.

[0054] It should be noted that during the descending process of the drilling assembly 2, it contacts the side wall surface of the handle earlier than the pre-positioning assembly 3.

[0055] Refer toFigures 6-8 , Further, the punching motor 21 is located at the top of the bearing plate 19. One end of the punching motor 21 is also provided with a base 211. The top of the base 211 is provided with a fixed shell 212. One end of the fixed shell 212 is connected to the outer wall of the punching motor 21. The output end of the punching motor 21 penetrates through the side wall of the fixed shell 212 and is connected to a worm 22. The worm 22 is located inside the fixed shell 212; the side of the worm gear 23 away from the connecting block 24 is rotatably connected to the inner wall of the fixed shell 212, and the reciprocating block 26 can be slidably connected inside the fixed shell 212; one end of the fixed shell 212 away from the punching motor 21 is also provided with a main chain shell 213. The main chain shell 213 is vertically bent, and a chain belt 27 can be fitted and inserted into the main chain shell 213.

[0056] Among them, when punching, the punching motor 21 is started to drive the worm 22 to rotate. Since the worm 22 is in meshing transmission with the worm gear 23, the worm gear 23 will also rotate, and drive the connecting block 24 to rotate synchronously, so that the connecting block 24 drives the reciprocating plate 25 to be pulled back or pushed out. The reciprocating block 26 moves along with the reciprocating plate 25 and drives the chain belt 27 to be pulled back or pushed out synchronously inside the main chain shell 213, so that the chain belt 27 drives the drilling member 28 to start and punch the side wall surface of the bent handle.

[0057] Refer to Figures 6-8 , Still further, the drilling member 28 includes a support plate 281, a micro gear 282 provided at the top, and a drill bit 283 provided at the bottom of the micro gear 282; the support plate 281 is U-shaped. One end of the support plate 281 is connected to one end of the main chain shell 213 away from the fixed shell 212. The micro gear 282 is in meshing transmission with the chain belt 27. One end of the drill bit 283 penetrates through the top of the support plate 281 and is connected to the micro gear 282.

[0058] Among them, during the process of the chain belt 27 being pulled back or pushed out synchronously inside the main chain shell 213, since the micro gear 282 is in meshing transmission with the chain belt 27, the chain belt 27 will drive the micro gear 282 to rotate, so that the drill bit 283 rotates synchronously, thus achieving the purpose of punching.

[0059] Embodiment 3. Through the technical solutions of Embodiment 1 and Embodiment 2, although the problem that the existing clamping device only simply fits and fixes the side of the handle, and there will be a downward extrusion force during the punching process to push the handle, causing the handle to turn and shift, and the convex surface of the bent handle is located directly above the position to be drilled, resulting in the bent handle interfering with the punching mechanism to punch, has been solved. However, the following problems have not been solved yet: the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface; for this reason, the following solution is now proposed: Refer to Figures 9-12, Further, one end of the extension plate 31 is also provided with a secondary chain housing 311. The end of the secondary chain housing 311 away from the extension plate 31 is connected to the end of the support plate 281 away from the main chain housing 213. The chain belt 27 can be fitted and inserted into the secondary chain housing 311; the height differences of the first gear 321, the second gear 331, and the third gear 341 are distributed in sequence from short to long, and one end of the fixed column 35 is connected to the middle of the bottom end of the extension plate 31.

[0060] Refer to Figures 9-12 , Still further, the adjusting member 36 includes a first secondary tooth 361, a first secondary column 362 disposed on one side of the first secondary tooth 361, a first secondary bar 363 disposed at the end of the first secondary column 362 away from the first secondary tooth 361, a first secondary rod 364 rotatably connected to the end of the first secondary bar 363 away from the first secondary column 362, a second secondary tooth 365 sleeved on the first secondary column 362, a second secondary column 366 disposed on one side of the second secondary tooth 365, a second secondary bar 367 disposed at the end of the second secondary column 366 away from the second secondary tooth 365, a second secondary rod 368 rotatably connected to the end of the second secondary bar 367 away from the second secondary column 366, a third secondary tooth 369 sleeved on the second secondary column 366, a third secondary bar 3610 disposed on one side of the third secondary tooth 369, and a third secondary rod 3611 rotatably connected to the end of the third secondary bar 3610 away from the third secondary tooth 369; the first secondary bar 363, the second secondary bar 367, and the third secondary bar 3610 are all L-shaped, the first secondary rod 364, the second secondary rod 368, and the third secondary rod 3611 are all inclinedly distributed, the end of the first secondary rod 364 away from the first secondary bar 363 is rotatably connected to the outer wall of the adjusting plate 37, the end of the second secondary rod 368 away from the second secondary bar 367 is rotatably connected to the outer wall of the adjusting plate 37, and the end of the third secondary rod 3611 away from the third secondary bar 3610 is rotatably connected to the outer wall of the adjusting plate 37; the first gear 321 is in meshing transmission with the first secondary tooth 361; the second gear 331 is in meshing transmission with the second secondary tooth 365; the third gear 341 is in meshing transmission with the third secondary tooth 369.

[0061] Wherein, when the surface of the handle to be punched is an inclined surface, it is necessary to perform pre-positioning strikes on the position to be punched at this time, so that pre-positioned holes appear on the surface to be punched.

[0062] When the hole for pre-positioning strike is within the rotation range of the first auxiliary rod 364, the first motor 32 starts, driving the first gear 321 to rotate, so that the first auxiliary gear 361 rotates synchronously, and drives the first auxiliary column 362 and the first auxiliary bar 363 to rotate synchronously, causing the first auxiliary bar 363 to drive the first auxiliary rod 364 to rotate and shift. At this time, the first auxiliary rod 364 will pull the adjusting plate 37 to perform an angular flip in the direction of the first auxiliary rod 364, so that the striking member 38 flips synchronously, making the striking member 38 always perpendicular to the surface to be drilled. When the drilling assembly 2 drills a hole, only the hole after striking needs to be used to clamp and position the drilling assembly 2, thus realizing the pre-positioning before drilling, avoiding the situation that the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface, thereby improving the drilling accuracy and further improving the production efficiency of the handle.

[0063] When the hole for pre-positioning strike is within the rotation range of the second auxiliary rod 368, the second motor 33 starts, driving the second gear 331 to rotate, so that the second auxiliary gear 365 rotates synchronously, and drives the second auxiliary column 366 and the second auxiliary bar 367 to rotate synchronously, causing the second auxiliary bar 367 to drive the second auxiliary rod 368 to rotate and shift. At this time, the second auxiliary rod 368 will pull the adjusting plate 37 to perform an angular flip in the direction of the second auxiliary rod 368, so that the striking member 38 flips synchronously, making the striking member 38 always perpendicular to the surface to be drilled. When the drilling assembly 2 drills a hole, only the hole after striking needs to be used to clamp and position the drilling assembly 2, thus realizing the pre-positioning before drilling, avoiding the situation that the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface, thereby improving the drilling accuracy and further improving the production efficiency of the handle.

[0064] When the hole for pre-positioning strike is within the rotation range of the third auxiliary rod 3611, the third motor 34 starts, driving the third gear 341 to rotate, so that the third auxiliary gear 369 rotates synchronously, and drives the third auxiliary bar 3610 to rotate synchronously, causing the third auxiliary bar 3610 to drive the third auxiliary rod 3611 to rotate and shift. At this time, the third auxiliary rod 3611 will pull the adjusting plate 37 to perform an angular flip in the direction of the third auxiliary rod 3611, so that the striking member 38 flips synchronously, making the striking member 38 always perpendicular to the surface to be drilled. When the drilling assembly 2 drills a hole, only the hole after striking needs to be used to clamp and position the drilling assembly 2, thus realizing the pre-positioning before drilling, avoiding the situation that the surface of the handle is uneven, resulting in the drill bit shifting on the uneven surface, thereby improving the drilling accuracy and further improving the production efficiency of the handle.

[0065] When the surface of the handle to be punched is a horizontal surface, the first motor 32, the second motor 33, and the third motor 34 are started simultaneously at this time, and drive the corresponding first gear 321, second gear 331, and third gear 341 to rotate, so that the adjusting member 36 can be rotated horizontally as a whole at the same time, and the adjusting plate 37 rotates accordingly, so that the striking member 38 can be rotated above the position to be pre-positioned and struck.

[0066] Finally, by rotating the corresponding auxiliary rod, the flipping angle of the striking member 38 is adjusted, so that the striking member 38 always maintains a vertical state with the surface to be punched, realizing accurate striking.

[0067] Refer to Figure 9 Furthermore, the striking member 38 includes a striking cylinder 381 and a striking head 382 provided at the telescopic end of the striking cylinder 381; the telescopic end of the striking cylinder 381 passes through the bottom of the adjusting plate 37 and is connected to the striking head 382.

[0068] Among them, when the striking cylinder 381 is started, its telescopic end pushes the striking head 382 to strike and position the surface to be punched. During this process, the striking head 382 always maintains a vertical state with the surface to be punched. When the punching assembly 2 punches, only the hole after striking needs to be used to clamp and position the punching assembly 2, so as to realize the pre-positioning before punching, avoid the situation that the surface of the handle is uneven and the drill bit deviates on the uneven surface, thereby improving the punching accuracy and further improving the production efficiency of the handle.

[0069] Embodiment 4, a positioning and punching method for door lock processing, using the positioning and punching device for door lock processing as described above, including the following steps: S1. Before punching the side wall of the bent handle, first place the bent handle vertically, and then the fixing assembly 1 is started to squeeze and clamp the surface of the bent handle.

[0070] S2. Under the condition of being clamped by the fixing assembly 1, the pre-positioning assembly 3 strikes and positions the surface of the bent handle to be punched.

[0071] S3. When punching, the punching motor 21 is started to drive the worm 22 to rotate. Since the worm 22 is in meshing transmission with the worm gear 23, the worm gear 23 will also rotate, and drive the connecting block 24 to rotate synchronously, so that the connecting block 24 drives the reciprocating plate 25 to be pulled back or pushed out. The reciprocating block 26 displaces along with the reciprocating plate 25 and drives the chain belt 27 to be pulled back or pushed out synchronously, so that the chain belt 27 drives the drilling member 28 to start and punch the side wall of the bent handle.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
