Description

Technical Field

[0001] This invention belongs to the field of metal lock case processing machinery technology, specifically relating to a positioning and adjustment processing device and method for machining center grooves in lock cases. Background Technology

[0002] Lock case machining refers to the process of mechanically processing the outer shell of a lock. This typically involves operations such as cutting, drilling, and milling to ensure the lock shell meets design requirements, effectively accommodates internal components like the lock cylinder and bolt, and provides sufficient strength and durability. This process is a crucial step in lock manufacturing, affecting both the lock's functionality and security.

[0003] Chinese patent application number 202410993339.X discloses a lock shell and lock cylinder hole internal suction processing positioning device, including a support platform, a lifting platform that moves vertically along the upper edge of the support platform, and two positioning seats that move in opposite directions on the lifting platform. Each positioning seat has several shape-matching positioning plates that slide horizontally from top to bottom. This patent solves the problem in traditional positioning devices that, when fixing the lock shell, due to the irregular shape of the lock shell, cause the existing positioning mechanism to clamp the side or bottom of the lock shell under the downward pressure of the drilling machine, the lock shell is prone to displacement, which affects the drilling accuracy and causes product damage.

[0004] In the lock case manufacturing process, the lock case strip is generally cut into individual lock cases first, and then the lock cases are fixed and the central groove is cut. This secondary cutting method can lead to workpiece wobbling during clamping, causing the cut surfaces of the lock case edges and the central groove to be non-parallel. This can result in unevenness during subsequent installation, causing quality issues and problems with the later installation of the lock cylinder. Secondly, because the lock case is cut first and then the central groove is cut while the lock case is clamped and fixed, the secondary clamping during the cyclic cutting process can cause the central groove positions of the front and rear lock cases to be different. This can potentially affect the dimensional uniformity of batch processing, making it difficult to install some lock cases with other components. Furthermore, the clamping process typically only provides limiting clamping in one direction; if loosening occurs, the cutting will have a significant deviation. For some complex components that can be stably clamped, cutting and flexible replacement are inconvenient, resulting in low processing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a positioning and adjustment processing device and method for machining center grooves in lock cases. Through the cooperation of the cutting mechanism and the positioning box, this invention not only ensures that the center groove of the lock case is always parallel to the cutting surface of the lock case edge, thus guaranteeing the precise dimensions of the lock case itself, but also ensures that the dimensions of the lock cases cut in a cycle remain consistent, avoiding the problem of partial component installation failure after subsequent batch processing. Through the cooperation of the clamping and adjustment mechanism, the cycle switching mechanism, and the push tube mechanism, this invention ensures that the horizontal and vertical directions of the lock case strip remain stable during the lock case cutting process, ensuring consistent dimensions of the cyclically cut lock cases without affecting the cutting process. Furthermore, through the cooperation of the clamping and adjustment mechanism and the push tube mechanism, this invention ensures stable and deviation-free clamping and fixing for each cycle of cutting, is applicable to the processing of lock cases of different sizes, and is easy to replace.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning and adjustment processing device for machining center grooves in lock housings includes a base, on which a positioning box is fixedly installed for positioning the lock housing strip. The positioning box is equipped with a clamping and adjusting mechanism. A cutting processing mechanism is also fixedly installed on the top of the base, on which a center groove cutter and a lock housing cutter are mounted. The center groove cutter is located above the lock housing strip, and the lock housing cutter is located below the lock housing strip. The center groove cutter and the lock housing cutter are fixed together and move vertically simultaneously.

[0008] Furthermore, the cutting and processing mechanism includes a fixed plate fixed on the base, a first vertical rail fixedly mounted on the fixed plate, and a first vertical rail slider slidably connected on the first vertical rail; an L-shaped mounting plate fixedly connected to the first vertical rail slider, and a groove cutting machine and a lock shell cutting machine respectively mounted at both ends of the L-shaped mounting plate; a push plate is fixedly mounted at the bottom of the L-shaped mounting plate and the first vertical rail slider, and a first electric telescopic rod is fixedly mounted on the base, with the telescopic end of the first electric telescopic rod fixedly connected to the push plate.

[0009] Furthermore, the two first cutting blades of the slot cutter are located directly above the lock housing strip, and the second cutting blade of the lock housing cutter is located on the lower side of the lock housing strip.

[0010] Furthermore, the L-shaped mounting plate has a first adjustment slot and a second adjustment slot at each end; the top of both the first and second adjustment slots has a threaded opening and a locking screw is screwed in; the body of the slot cutting machine is fixedly provided with a first adjustment block, which is inserted into the first adjustment slot; the body of the lock shell cutting machine is fixedly provided with a second adjustment block, which is inserted into the second adjustment slot.

[0011] Furthermore, the clamping and adjusting mechanism includes a stepper motor. The top of the positioning box has a sliding groove, one end of which is fixedly connected to a fixed clamping block; the other end of the sliding groove is slidably connected to a movable clamping block; one end of the sliding groove has a through hole, and the movable clamping block has a threaded hole, on which an adjusting screw is screwed; one end of the adjusting screw passes through the through hole and is fixedly connected to the output end of the stepper motor, and the other end of the adjusting screw is rotatably connected to the fixed clamping block through a bearing; the stepper motor is fixedly installed on one side of the positioning box.

[0012] Furthermore, a fixed clamping plate is fixedly provided on the top of the fixed clamping block, and a movable clamping plate is fixedly provided on the top of the movable clamping block. The locking strip is located between the fixed clamping plate and the movable clamping plate. A transverse slot is provided on one side of both the fixed clamping plate and the movable clamping plate. A circulation switching mechanism is provided on the transverse slot. The circulation switching mechanism includes a slide fixed to the top of the base. Two track slots are provided on the slide. A second track slider is slidably connected to the track slot. The two second track sliders are fixedly connected to the rod body of the second electric telescopic rod. A push tube mechanism is sleeved on the telescopic end of the second electric telescopic rod. The locking strip includes a locking tube and a locking block that are fixed to each other. The locking tube is sleeved on the push tube mechanism.

[0013] Furthermore, the pushing tube mechanism includes a plastic positioning tube and a limiting tube sleeved on the telescopic end. An abutting ring block is fixedly connected to the middle of the outer side of the limiting tube, and an abutting plate is fixedly connected to the bottom of the abutting ring block. The abutting ring block abuts against the locking shell tube, and the abutting plate abuts against the locking shell block. The plastic positioning tube and the limiting tube are respectively inserted into the transverse slots of the corresponding fixed clamping plate and the moving clamping plate.

[0014] Furthermore, telescopic holes are provided around one side wall of the telescopic end, and telescopic blocks are slidably connected inside the telescopic holes. The telescopic blocks are fixedly connected to the inner bottom of the telescopic holes by springs.

[0015] Furthermore, the top two sides of the fixed clamping block are provided with inclined surfaces, and one side of the fixed clamping block is provided with a waste pipe groove, which is installed on the top of the base.

[0016] This invention also claims a method for machining using the above-described positioning and adjustment machining device for machining center grooves in lock housings, comprising the following steps:

[0017] S1. Insert the positioning tube and the limiting tube at both ends of the lock housing strip, and then put them together on the telescopic end of the second electric telescopic rod; push the second electric telescopic rod so that the positioning tube and the limiting tube are respectively inserted into the horizontal slots of the corresponding fixed clamping plate and the moving clamping plate for horizontal stability; at this time, under the gravity of the lock housing strip, the lock housing block automatically moves vertically downward, and the stepper motor is started so that the fixed clamping plate and the moving clamping plate clamp and fix the lock housing strip for vertical stability.

[0018] S2. Start the second electric telescopic rod to retract its telescopic end so that the telescopic end will not be cut by the cutting machine; then start the first electric telescopic rod to retract, and use the slot cutting machine to cut the slot and part of the lock shell edge; after cutting is completed, start the second electric telescopic rod to restore it. When the end of the telescopic end passes the slot on the edge of the lock shell, the telescopic block will extend and push out the cut plastic positioning tube that was left inside the lock shell strip.

[0019] S3. Then, start the second electric telescopic rod to retract its telescopic end so that the telescopic end will not be cut by the cutting machine; and start the first electric telescopic rod to extend it, so that the lock case is completely cut out by the lock case cutting machine, thereby ensuring that the cutting surfaces of the middle groove and the edge of the lock case are always parallel; after the cutting is completed, the first electric telescopic rod returns to its original position.

[0020] S4. Continue to start the stepper motor to clamp and fix the remaining lock housing strip, and then repeat the S2~S3 cycle to cut the lock housing; after cutting, pull out the second electric telescopic rod to replace the new lock housing strip.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This invention, through the cooperation of the cutting and processing mechanism and the positioning box, not only ensures that the cutting surfaces of the lock shell's central groove and the edge of the lock shell are always parallel, thus guaranteeing the precise dimensions of the lock shell itself, but also ensures that the dimensions of the lock shells formed by cyclic cutting are consistent, avoiding the problem of some parts failing to install after subsequent batch processing; specifically, when the lock shell strip is clamped and fixed on the positioning box, since the L-shaped mounting plate and the first vertical track slider are slidably connected on the first vertical track, and both the central groove cutting machine and the lock shell cutting machine are mounted on the L-shaped mounting plate; at this time, through the extension and retraction of the first electric telescopic rod, This allows for synchronized vertical movement of the slot cutting machine and the lock case cutting machine, ensuring the cutting surfaces remain constant. This guarantees that the cut surfaces of the slot and lock case edges are always parallel, ensuring precise lock case dimensions and preventing unevenness during subsequent installation on locks. Furthermore, after cutting one lock case, the horizontal alignment of the slot and lock case cutting machines remains constant, ensuring consistent dimensions for all cyclically cut lock cases and preventing assembly failures in subsequent batch processing.

[0023] (2) This invention, through the cooperation of the clamping adjustment mechanism, the cycle switching mechanism, and the push tube mechanism, can ensure that the lock shell strip remains stable in both the horizontal and vertical directions during the lock shell cutting process, so that the size of the lock shells cut in the cycle is consistent and does not affect the cutting process; at the same time, it can also automatically remove the plastic positioning tubes remaining in the lock shell strip, greatly improving the processing efficiency; specifically, when the cutting process is carried out, the positioning tubes and limiting tubes are inserted at both ends of the lock shell strip and together fitted onto the telescopic end of the second electric telescopic rod; the second electric telescopic rod is pushed so that the positioning tubes and limiting tubes are respectively inserted into the horizontal slots of the corresponding fixed clamping plate and the moving clamping plate for horizontal stability; at this time, under the gravity of the lock shell strip, the lock shell block automatically moves vertically downward, and the stepper motor is started so that the fixed clamping plate and the moving clamping plate clamp and fix the lock shell strip for vertical stability; thus, it can ensure that all lock shells cut from the lock shell strip are stable in the vertical direction. All shells are of uniform size, eliminating the issue of significant dimensional deviations caused by sequential cutting. Furthermore, during cutting, the retraction of the second electric telescopic rod prevents it from being cut by the cutting machine. The positioning and limiting tubes ensure stable clamping without compromising the clamping stability and prevent the metal telescopic end inside the lock shell from obstructing the process, thus avoiding the problem of only being able to position the lock shell without being able to cut. Simultaneously, during cutting, the first electric telescopic rod retracts, allowing the slot cutting machine to cut the slot and part of the lock shell edge. After cutting, the second electric telescopic rod returns to its original position. When the end of the telescopic rod passes the slot on the edge of the lock shell, the telescopic block extends and pushes out any remaining cut plastic positioning tubes inside the lock shell strip. This automatically removes any remaining plastic positioning tubes from the lock shell strip, preventing subsequent difficult cleaning and significantly improving processing efficiency.

[0024] (3) The present invention, through the cooperation of the clamping adjustment mechanism and the pushing tube mechanism, can ensure that the clamping and fixing is stable and without deviation for each cyclic cutting, and can be applied to the processing of lock shells of different sizes. Specifically, after a complete lock shell is cut out, since the two ends of the limiting tube are still inserted into the lock shell tube and the transverse groove of the moving clamping plate, the remaining lock shell strip is still limited and will not fall off. At this time, under the drive of the stepper motor, the moving clamping plate moves closer to the fixed clamping plate. Due to the synchronous pushing of the abutting ring block and the abutting plate, the lock shell strip is clamped and fixed, which can ensure that the clamping and fixing is stable and without deviation for each cyclic cutting. At the same time, according to the lock shell tube size of different lock shell strips, the plastic positioning tube and limiting tube of the corresponding size can be replaced, without the need to replace the second electric telescopic rod, thus making it applicable to the processing of lock shells of different sizes.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items. Example

[0039] like Figures 1-10 As shown, a positioning and adjustment processing device for machining center grooves in lock housings includes a base 100. A positioning box 200 is fixedly installed on the base 100 for positioning the lock housing strip 300. A clamping and adjustment mechanism is installed on the positioning box 200. A cutting processing mechanism 600 is also fixedly installed on the top of the base 100. A center groove cutting machine 640 and a lock housing cutting machine 650 are installed on the cutting processing mechanism 600. The center groove cutting machine 640 is located above the lock housing strip 300, and the lock housing cutting machine 650 is located below the lock housing strip 300. The center groove cutting machine 640 and the lock housing cutting machine 650 are fixed together and move up and down simultaneously.

[0040] This invention, through the cooperation of the cutting and processing mechanism 600 and the positioning box 200, not only ensures that the cutting surfaces of the central groove and the edge of the lock case are always parallel, thus guaranteeing the precise dimensions of the lock case itself, but also ensures that the lock cases formed by cyclic cutting maintain consistent dimensions, avoiding the problem of some parts failing to be installed after subsequent batch processing; a detailed description will follow.

[0041] Furthermore, the cutting and processing mechanism 600 includes a fixing plate 610 fixed on the base 100, a first vertical rail 611 fixedly mounted on the fixing plate 610, and a first vertical rail slider 621 slidably connected to the first vertical rail 611; an L-shaped mounting plate 620 fixedly connected to the first vertical rail slider 621, and a groove cutting machine 640 and a lock shell cutting machine 650 respectively mounted at both ends of the L-shaped mounting plate 620; a push plate 622 is fixedly mounted at the bottom of the L-shaped mounting plate 620 and the first vertical rail slider 621, and a first electric telescopic rod 630 is fixedly mounted on the base 100, with the telescopic end of the first electric telescopic rod 630 fixedly connected to the push plate 622.

[0042] When the lock shell strip 300 is clamped and fixed on the positioning box 200, since the L-shaped mounting plate 620 and the first vertical track slider 621 are slidably connected on the first vertical track 611, and both the slot cutting machine 640 and the lock shell cutting machine 650 are mounted on the L-shaped mounting plate 620, the extension and retraction of the first electric telescopic rod 630 can control the slot cutting machine 640 and the lock shell cutting machine 650 to move up and down synchronously, so that the cutting surface remains unchanged. This ensures that the slot cut by the slot cutting machine 640 and the edge of the lock shell cut by the lock shell cutting machine 650 are always parallel, thereby ensuring the accurate size of the lock shell itself and avoiding the problem of uneven surface when it is installed on the lock. At the same time, after cutting a complete lock shell, when continuing to cut the next lock shell, since the slot cutting machine 640 and the lock shell cutting machine 650 remain unchanged in the horizontal direction, the lock shells formed by the cyclic cutting can maintain consistent size, avoiding the problem of some parts failing to be installed after batch processing.

[0043] It is worth noting that the cutting machine and the first electric telescopic rod 630 of this invention are powered by an external power source, which is a mature existing technology and will not be described in detail here.

[0044] Furthermore, the two first cutting blades 641 of the slot cutter 640 are located directly above the lock housing strip 300, and the second cutting blade 651 of the lock housing cutter 650 is located on the lower side of the lock housing strip 300.

[0045] With this structural design, the two first cutting blades 641 of the slot cutting machine 640 first cut out the slot and part of the lock shell edge, and the second cutting blade 651 of the lock shell cutting machine 650 cuts out the remaining lock shell edge. The two cutting processes ensure that the cutting surfaces are always parallel. If they are not parallel, there will be concave or convex marks between the upper and lower lock shell edges, which also allows for quick judgment of the cutting quality.

[0046] It is worth noting that the accompanying drawings in this invention specification are only schematic diagrams and are sufficient to fulfill the function. No further limitation is made on the specific dimensions. They can be flexibly adjusted according to the actual situation. For example, the size of the first cutting blade 641 and the second cutting blade 651 can be flexibly set.

[0047] Furthermore, the L-shaped mounting plate 620 has a first adjustment slot 643 and a second adjustment slot 653 respectively opened at both ends; the top of the first adjustment slot 643 and the second adjustment slot 653 are both threaded and screwed with locking screws; the body of the slot cutting machine 640 is fixedly provided with a first adjustment block 642, which is inserted into the first adjustment slot 643; the body of the lock shell cutting machine 650 is fixedly provided with a second adjustment block 652, which is inserted into the second adjustment slot 653.

[0048] The position of the cutting disc can be quickly adjusted by adjusting the first adjusting block 642 and the second adjusting block 652 with the locking screw, allowing for flexible adjustment to meet the needs of different lock case sizes.

[0049] Furthermore, the clamping and adjusting mechanism includes a stepper motor 900. The top of the positioning box 200 is provided with a sliding groove 210, and a fixed clamping block 230 is fixedly connected to one end of the sliding groove 210. A movable clamping block 220 is slidably connected to the other end of the sliding groove 210. A through hole 211 is provided through one end of the sliding groove 210, and a threaded hole is provided through the movable clamping block 220. An adjusting screw 910 is screwed into the threaded hole. One end of the adjusting screw 910 passes through the through hole 211 and is fixedly connected to the output end of the stepper motor 900. The other end of the adjusting screw 910 is rotatably connected to the fixed clamping block 230 through a bearing 232. The stepper motor 900 is fixedly installed on one side of the positioning box 200.

[0050] The stepper motor 900 drives the adjusting screw 910 to rotate, which in turn moves the movable clamping block 220 laterally on the slide groove 210 to achieve clamping and releasing operations. The stepper motor 900 is a mature existing technology and will not be described in detail here.

[0051] Furthermore, a fixed clamping plate 231 is fixedly provided on the top of the fixed clamping block 230, and a movable clamping plate 221 is fixedly provided on the top of the movable clamping block 220. The locking strip 300 is located between the fixed clamping plate 231 and the movable clamping plate 221. A horizontal slot is provided on one side of both the fixed clamping plate 231 and the movable clamping plate 221. A circulation switching mechanism 400 is provided on the horizontal slot. The circulation switching mechanism 400 includes a slide block 430 fixed to the top of the base 100. Two track grooves 431 are provided on the slide block 430. A second track slider 420 is slidably connected to the track grooves 431. The two second track sliders 420 are fixedly connected to the rod body of the second electric telescopic rod 410. A push tube mechanism 500 is sleeved on the telescopic end 411 of the second electric telescopic rod 410. The locking strip 300 includes a locking tube 310 and a locking block 320 fixed to each other. The locking tube 310 is sleeved on the push tube mechanism 500.

[0052] This invention, through the cooperation of the clamping adjustment mechanism, the circulation switching mechanism 400, and the pushing tube mechanism 500, can ensure that the lock case strip 300 remains stable in both the horizontal and vertical directions during the lock case cutting process, so that the lock case cut in each cycle is of consistent size and does not affect the cutting process; at the same time, it can automatically remove the plastic positioning tube 513 remaining in the lock case strip 300, which greatly improves the processing efficiency; a detailed description will follow.

[0053] Furthermore, the pushing tube mechanism 500 includes a plastic positioning tube 513 and a limiting tube 512 sleeved on the telescopic end 411. An abutting ring block 510 is fixedly connected to the middle of the outer side of the limiting tube 512, and an abutting plate 511 is fixedly connected to the bottom of the abutting ring block 510. The abutting ring block 510 abuts against the locking shell tube 310, and the abutting plate 511 abuts against the locking shell block 320. The plastic positioning tube 513 and the limiting tube 512 are respectively inserted into the transverse grooves of the corresponding fixed clamping plate 231 and the movable clamping plate 221. The locking shell tube 310 is sleeved on the plastic positioning tube 513 and one side of the limiting tube 512.

[0054] Furthermore, telescopic holes 412 are provided around one side wall of the telescopic end 411, and telescopic blocks 413 are slidably connected inside the telescopic holes 412. The telescopic blocks 413 are fixedly connected to the inner bottom of the telescopic holes 412 by springs 414.

[0055] When the present invention is being cut, the plastic positioning tube 513 and the limiting tube 512 are inserted at both ends of the lock shell strip 300 and together fitted onto the telescopic end 411 of the second electric telescopic rod 410. The second electric telescopic rod 410 is pushed so that the plastic positioning tube 513 and the limiting tube 512 are respectively inserted into the horizontal slots of the corresponding fixed clamping plate 231 and moving clamping plate 221 for horizontal stability. At this time, under the gravity of the lock shell strip 300, the lock shell block 320 automatically moves vertically downwards, and the stepper motor 900 is activated to clamp and fix the lock shell strip 300 with the fixed clamping plate 231 and moving clamping plate 221 for vertical stability, eliminating the need for repeated adjustments. This ensures that all lock shells cut from the lock shell strip 300 are of consistent size, preventing large dimensional deviations caused by sequential cutting. Moreover, during cutting, the telescopic end 411 of the second electric telescopic rod 410 retracts, preventing the telescopic end 411 from being... During the cutting process, the plastic positioning tube 513 and the limiting tube 512 limit the movement, ensuring stable clamping without affecting the clamping effect. This also prevents the metal telescopic end 411 inside the lock housing strip 300 from obstructing the movement and causing the machine to only position the lock but not cut, thus avoiding increased cutting difficulty to maintain clamping stability. Simultaneously, during cutting, the first electric telescopic rod 630 retracts, and the groove cutting machine 640 cuts the groove and part of the lock housing edge. After cutting, the second electric telescopic rod 410 retracts. When the end of the telescopic end 411 passes the groove on the edge of the lock housing, the telescopic block 413 extends and pushes out the cut plastic positioning tube 513 remaining inside the lock housing strip 300, automatically removing the remaining plastic positioning tube 513 from the lock housing strip 300. This prevents the subsequent removal of the plastic positioning tube 513 remaining inside the lock housing, greatly improving processing efficiency.

[0056] This invention, through the cooperation of the clamping adjustment mechanism and the pushing tube mechanism 500, can ensure stable and error-free clamping during cyclic cutting, and is applicable to the processing of lock cases of different sizes, while also facilitating replacement. Specifically, after a complete lock case is cut, since both ends of the limiting tube 512 are still inserted into the lock case tube 310 and the transverse slot of the moving clamping plate 221, the remaining lock case strip 300 is still limited and will not fall off. At this time, driven by the stepper motor 900, the moving clamping plate 221 moves closer to the fixed clamping plate 231. Due to the simultaneous movement of the abutment ring block 510 and the abutment plate 511... The mechanism pushes the device forward, thereby continuing to clamp and fix the lock housing strip 300, ensuring stable clamping and fixation without deviation during cyclic cutting. Simultaneously, depending on the size of the lock housing tube 310 of different lock housing strips 300, the corresponding size plastic positioning tube 513 and limiting tube 512 can be replaced without replacing the second electric telescopic rod 410, thus making it suitable for processing lock housings of different sizes. Furthermore, due to the structural design of the cyclic switching mechanism 400 of this application, clamping stability and cutting operations can be achieved without front-to-back direction limiting, allowing for convenient and quick replacement via forward and backward pushing.

[0057] Furthermore, the fixed clamping block 230 has inclined surfaces on both sides of its top, and a waste pipe groove 800 is provided on one side of the fixed clamping block 230. The waste pipe groove 800 is installed on the top of the base 100.

[0058] The inclined plane is used to guide waste materials and lock housings, and the waste pipe groove 800 is used to collect waste pipes.

[0059] It is worth noting that when the locking strip 300 of the present invention is cut to the last part, there will be a small section that cannot be cut and is considered waste. It can also be used as a semi-finished product for separate slotting operation, which will not be described in detail here.

[0060] A method for machining using the above-mentioned positioning and adjustment machining device for machining center grooves in lock housings includes the following steps:

[0061] S1. Insert the plastic positioning tube 513 and the limiting tube 512 at both ends of the lock housing strip 300, and then put them together on the telescopic end 411 of the second electric telescopic rod 410; push the second electric telescopic rod 410 so that the plastic positioning tube 513 and the limiting tube 512 are respectively inserted into the horizontal slots of the corresponding fixed clamping plate 231 and the moving clamping plate 221 for horizontal stability; at this time, under the gravity of the lock housing strip 300, the lock housing block 320 automatically moves vertically downward, and the stepper motor 900 is started so that the fixed clamping plate 231 and the moving clamping plate 221 clamp and fix the lock housing strip 300 for vertical stability;

[0062] S2. Start the second electric telescopic rod 410 to retract the telescopic end 411 so that the telescopic end 411 will not be cut by the cutting machine; then start the first electric telescopic rod 630 to retract, and cut the middle groove and part of the lock shell edge by the middle groove cutting machine 640; after the cutting is completed, start the second electric telescopic rod 410 to restore it. When the end of the telescopic end 411 passes the groove of the lock shell edge, the telescopic block 413 will extend and push out the plastic positioning tube 513 that was cut off inside the lock shell strip 300.

[0063] S3. Then, the telescopic end 411 of the second electric telescopic rod 410 is retracted so that the telescopic end 411 will not be cut by the cutting machine; and the first electric telescopic rod 630 is extended so that the lock case is completely cut out by the lock case cutting machine 650, thereby ensuring that the cutting surfaces of the middle groove and the edge of the lock case are always parallel; after the cutting is completed, the first electric telescopic rod 630 is restored.

[0064] S4. Continue to start the stepper motor 900 to clamp and fix the remaining lock housing strip 300, and then repeat the S2~S3 cycle to cut the lock housing; after cutting, pull out the second electric telescopic rod 410 to replace the new lock housing strip 300.

[0065] It is worth noting that the end of the telescopic block 413 is curved. Figure 5 The attached diagram is for illustrative purposes only; and the elastic force of the spring 414 can be flexibly adjusted according to the actual situation, so that the push of the telescopic end 411 can push out the plastic positioning tube 513 that is cut off inside the lock housing strip 300. This is a standard setting and will not be described in detail here.

[0066] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
