Description

Technical Field

[0001] This invention relates to the field of lock manufacturing technology, specifically an automatic drilling device for lock cylinder components. Background Technology

[0002] As the core component of a lock, the padlock cylinder consists of a cylindrical cylinder body, a keyhole oriented along the cylinder body's axis, and multiple pin holes evenly distributed along the cylinder body's axis. The keyhole is used for key insertion to drive the cylinder's rotation, while the pin holes are used to install pins and springs. It is a key structure for realizing the locking and unlocking functions of the lock. In the manufacturing process of the lock cylinder, after the keyhole groove is machined, multiple pin holes need to be precisely machined on the cylinder body to ensure the assembly accuracy of the subsequent pin components and the security of the lock.

[0003] Currently, the processing of lock cylinder pin holes is mostly completed using automated drilling equipment. Existing equipment automatically orients, sorts, and transports lock cylinders with completed keyhole grooves to the fixture worktable. After receiving the lock cylinder, the fixture worktable uses its clamping mechanism to precisely position and clamp the lock cylinder. Subsequently, the drilling unit moves to a preset position under program control to drill the pin holes of the lock cylinder. After drilling is completed, the clamping mechanism of the fixture worktable releases the lock cylinder and pushes the processed lock cylinder out of the fixture through the built-in pushing mechanism (such as a cylinder push rod), allowing it to slide down the preset unloading plate, thus realizing the complete process of lock cylinder from automatic feeding, positioning and clamping, drilling processing to automatic unloading.

[0004] The following problems exist when drilling lock cylinders: metal shavings generated during drilling are easily left inside the lock cylinder. On the one hand, small shavings remain in the freshly drilled pin holes; on the other hand, shavings may also be scattered inside the keyhole. Conventional material cutting processes cannot effectively remove these residual shavings. If the residual shavings are not cleaned in time, they will cause the pins to not be installed properly and the spring compression to be abnormal in the subsequent pin assembly process. Therefore, before assembling the lock cylinder after drilling, it is usually necessary to manually clean the shavings on the lock cylinder, which affects the efficiency of subsequent lock assembly. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic drilling device for lock cylinder components, comprising a base, a drilling unit and a clamping worktable mounted on the upper left side of the base, and a chain conveyor mounted in the middle of the upper part of the base. Multiple chain plates on the chain conveyor are each equipped with a lock cylinder support platform for supporting the lock cylinder. An outer cleaning unit and an inner cleaning unit are mounted on the lock cylinder support platform. The outer cleaning unit includes a sliding cylinder slidably mounted on the lock cylinder support platform, with a cleaning assembly arranged on the inner arc-shaped surface of the sliding cylinder. The inner cleaning unit includes a vertical plate fixedly mounted on the front end of the lock cylinder support platform and fixedly connected to the chain plate. A reciprocating plate is mounted on the front end of the vertical plate via an elastic return rod. A vibrating plate is vertically slidably connected inside the reciprocating plate. The rear of the vibrating plate... A main cleaning rod is installed on the side; the reciprocating plate is connected to the front side of the sliding cylinder via an elastic transmission rod; two U-shaped frames arranged vertically are fixedly installed at the front end of the chain conveyor. Multiple actuating blocks and lifting blocks are evenly arranged horizontally on the upper and lower inner walls of the upper U-shaped frame, respectively. The bottom of the reciprocating plate is provided with a mating block that cooperates with the actuating block. An L-shaped rod is installed at the upper end of the shaking plate. The vertical section of the L-shaped rod passes through the reciprocating plate, and the horizontal section of the L-shaped rod cooperates with the lifting block. After the lock cylinder assembly is pushed into the sliding cylinder, as the chain conveyor moves forward and backward, the mating block contacts multiple actuating blocks, causing the reciprocating plate to move back and forth. At the same time, the L-shaped rod cooperates with multiple lifting blocks to cause the shaking plate to move up and down, so that the main cleaning rod on the reciprocating plate cleans the lock cylinder in multiple directions.

[0006] Preferably, the lock cylinder support platform is provided with a plurality of evenly arranged triangular support blocks, which are used to position the lock cylinder according to the groove at the bottom of the lock cylinder eye.

[0007] Preferably, both sides of the upper end of the sliding cylinder are equipped with a clamping assembly. The clamping assembly includes a clamping spring column fixedly installed on the upper end of the sliding cylinder. The telescopic end of the clamping spring column slides into the interior of the sliding cylinder, and a guide block is provided at the end of the clamping spring column. The guide block has an isosceles trapezoidal structure, and a roller is provided on the lower end face of the guide block.

[0008] Preferably, the cleaning assembly includes multiple arc-shaped mounting plates fixedly installed on the arc-shaped surface inside the sliding cylinder. The arc-shaped mounting plates are provided with brush bristles on the side near the center line of the sliding cylinder, and the lower side of the sliding cylinder is provided with a chip removal hole.

[0009] Preferably, an auxiliary cleaning rod is fixedly installed at the rear end of the reciprocating plate and below the main cleaning rod. Multiple upper blocks are fixedly installed at the upper end of the main cleaning rod. The main cleaning rod drives the lock cylinder to move up and down through the upper blocks, so that the auxiliary cleaning rod can move up and down relative to the lock cylinder to achieve cleaning of the keyhole in the vertical direction.

[0010] Preferably, the shaking plate is slidably connected to the reciprocating plate via a reset spring, and clearance holes are provided on the upright plate corresponding to the positions of the main cleaning rod and the auxiliary cleaning rod, with the main cleaning rod and the auxiliary cleaning rod interlaced within the clearance holes.

[0011] Preferably, the portions of the main cleaning rod and the auxiliary cleaning rod located inside the sliding cylinder are each provided with bristles. The rear end of the upright plate is fixedly installed with an installation ring via two vertically arranged connecting rods. Two horizontally arranged cleaning plates are fixedly installed at the rear end of the installation ring, and a cleaning plate with an elastic telescopic structure is fixedly installed on the upper side of the rear end of the installation ring.

[0012] Preferably, the two cleaning plates one and two are arranged at an angle to the rear and are pointed on opposite sides, and the two cleaning plates one and two are also arranged in a comb-like shape on opposite sides.

[0013] Preferably, a toggle plate is fixedly installed on the upper inner wall of the lower U-shaped frame. Both the toggle block and the toggle plate are provided with inclined surfaces that cooperate with the mating block. The lifting block is L-shaped and is provided with inclined surfaces that cooperate with the L-shaped rod.

[0014] Preferably, an elastic push rod is installed through and slidably back and forth on the reciprocating plate. The rear end of the elastic push rod slides through the vertical plate and is fixedly installed with a push plate. An active component is installed on the upper right side of the base. The active component drives the push plate corresponding to its position to push the lock cylinder backward through the elastic push rod.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention cleans debris from the outer wall of the lock cylinder and the keyhole by setting up a cleaning group and a main cleaning rod to clean the debris. Simultaneously, during the step-transfer of the lock cylinder, the invention uses a cooperating block with multiple actuating blocks and an L-shaped rod with multiple lifting blocks to enable the main cleaning rod to move back and forth while simultaneously moving up and down. This allows the main cleaning rod to clean the keyhole of the lock cylinder in multiple directions, thereby improving the cleaning effect on debris on the lock cylinder. Furthermore, the up-and-down movement of the main cleaning rod can drive the lock cylinder to move up and down, creating a shaking effect that allows debris to fall from the pin holes, improving the cleaning effect on debris inside the pin holes and ensuring the efficiency of subsequent lock assembly.

[0017] 2. This invention uses an auxiliary cleaning rod to assist in cleaning the keyhole of the lock cylinder. When the main cleaning rod causes the lock cylinder to vibrate up and down, the auxiliary cleaning rod moves up and down relative to the lock cylinder, thereby further improving the cleaning effect on the keyhole and reducing debris residue in the keyhole.

[0018] 3. When the main cleaning rod and the auxiliary cleaning rod move back and forth, the present invention cleans the debris remaining on the brush bristles by setting cleaning plate one and cleaning plate two. This prevents excessive debris from remaining on the brush bristles at the corresponding positions of the tumbler holes of the lock cylinder, thus affecting the cleaning effect on the lock cylinder and keyhole. After one lock cylinder is delivered, the debris remaining on the brush bristles is cleaned by cleaning plate one and cleaning plate two, reducing the amount of debris remaining on the brush bristles, thereby ensuring the cleaning effect on other lock cylinders.

[0029] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where no specific technology or conditions are specified in the embodiments, they shall be performed in accordance with the technology or conditions described in the literature in the field or in accordance with the product manual.

[0030] See Figure 1 , Figure 2 and Figure 3 An automatic drilling device for lock cylinder components includes a base 1, a drilling unit 2 and a fixture worktable 3 mounted on the upper left side of the base 1, a chain conveyor 4 mounted on the upper middle of the base 1, and a lock cylinder support platform 5 mounted on multiple chain plates 41 on the chain conveyor 4. An external cleaning unit 6 and an internal cleaning unit 7 are mounted on the lock cylinder support platform 5. The invention loads the lock cylinder onto the fixture worktable 3 manually or mechanically. Both the drilling unit 2 and the fixture worktable 3 employ existing technology. The drilling unit 2 uses a drill bit to automatically drill the pin holes of the lock cylinder. The fixture worktable 3 includes a fixture seat 31 and a pusher 32. The fixture seat 31 is used for positioning and clamping the lock cylinder. The fixture seat 31 has a circular clamping hole, and a processing groove communicating with the clamping hole is opened at the upper end of the fixture seat 31. The pusher 32 is used to push the drilled lock cylinder out of the fixture seat 31.

[0031] See Figure 2 , Figure 3 and Figure 5 The outer cleaning unit 6 includes a sliding cylinder 61 slidably mounted on the lock cylinder support platform 5, with a cleaning assembly on the inner arc-shaped surface of the sliding cylinder 61; the inner cleaning unit 7 includes a vertical plate 71 fixedly mounted on the front end of the lock cylinder support platform 5 and fixedly connected to the chain plate 41, with a reciprocating plate 73 mounted on the front end of the vertical plate 71 via an elastic return rod 72, and a vibrating plate 74 vertically slidably connected inside the reciprocating plate 73, with a main cleaning rod 75 mounted on the rear side of the vibrating plate 74; the reciprocating plate 73 is connected to the front side of the sliding cylinder 61 via an elastic transmission rod 76; the main cleaning rod 75... The cleaning rod 75 located inside the sliding cylinder 61 is equipped with bristles; a reinforcing rod is connected between the main cleaning rod 75 and the shaking plate 74 to increase its structural stability; the outer cleaning unit 6 and the inner cleaning unit 7 can clean the debris on the outer surface of the lock cylinder and inside the keyhole respectively while the lock cylinder is being driven by the stepping mechanism, thereby reducing debris residue. At the same time, the inner cleaning unit 7 can also shake the lock cylinder up and down, so that the debris inside the lock cylinder pin holes can be shaken off, improving the cleaning effect of the debris inside the lock cylinder pin holes and ensuring the efficiency of subsequent lock assembly.

[0032] To improve the cleaning effect of the main cleaning rod 75 on the lock cylinder and keyhole, this invention uses the main cleaning rod 75 to clean the keyhole in multiple directions. (See attached document.) Figure 1 , Figure 5 and Figure 6The front end of the chain conveyor 4 is fixedly installed with two U-shaped frames 42 arranged vertically. The upper and lower inner walls of the upper U-shaped frame 42 are respectively equipped with multiple actuating blocks 43 and lifting blocks 44 evenly arranged horizontally. The bottom of the reciprocating plate 73 is provided with a mating block 77 that cooperates with the actuating block 43. The upper end of the vibrating plate 74 is equipped with an L-shaped rod 78. The vertical section of the L-shaped rod 78 passes through the reciprocating plate 73, and the horizontal section of the L-shaped rod 78 cooperates with the lifting block 44.

[0033] Specifically, when drilling is required for the lock cylinder, the lock cylinder is first loaded into the clamping hole of the fixture seat 31. The fixture worktable 3 drives the position of the lock cylinder that needs to be drilled to the position of the drilling unit 2 in sequence, and the drilling operation is performed. After the drilling of the lock cylinder pin hole is completed, the fixture worktable 3 is controlled to drive the lock cylinder forward, and the pusher 32 is activated to push the lock cylinder out of the fixture seat 31. At this time, the lock cylinder support platform 5 at the corresponding position of the intermittently moving chain conveyor 4 corresponds to the position of the lock cylinder, so that the lock cylinder can move to the lock cylinder support platform 5 and be located in the sliding cylinder 61. The main cleaning rod 75 is inserted into the key hole of the lock cylinder. Then the chain plate 41 drives the corresponding lock cylinder to step to the right.

[0034] When the lock cylinder support platform 5 moves the lock cylinder to the right and to the position corresponding to the upper U-shaped frame 42, the mating block 77 moves to the position corresponding to the actuating block 43, and the L-shaped rod 78 moves to the position corresponding to the lifting block 44. As the chain conveyor 4 moves forward, the mating block 77 contacts multiple actuating blocks 43 and drives the reciprocating plate 73 to move back and forth under the action of the elastic return rod 72. The L-shaped rod 78 contacts multiple lifting blocks 44 and drives the shaking plate 74 to move up and down. The shaking plate 74 drives the main cleaning rod 75 to move up and down and back and forth at the same time, so that the bristles on the main cleaning rod 75 can clean the keyhole of the lock cylinder in multiple directions. When the main cleaning rod 75 contacts the lock cylinder and moves upward, the main cleaning rod 75 can drive the lock cylinder to shake up and down.

[0035] At the same time, the reciprocating plate 73 drives the sliding cylinder 61 to move back and forth through the elastic transmission rod 76, so that the sliding cylinder 61 drives the cleaning group to clean the outer surface of the lock cylinder. When the lock cylinder support platform 5 drives the lock cylinder to move to the right side below the chain conveyor 4, the lock cylinder is pushed out from the lock cylinder support platform 5 by manual or mechanical means, and the lock cylinder is collected manually to complete the unloading of the lock cylinder, thereby realizing continuous intermittent unloading and debris cleaning of the lock cylinder.

[0036] To prevent debris from accumulating inside the lock cylinder and on the lock cylinder support 5, refer to... Figure 3 and Figure 8The present invention employs a lock cylinder support platform 5 with multiple evenly arranged triangular support blocks 51. The support blocks 51 are used to position the lock cylinder according to the groove at the bottom of the lock cylinder, so that the multiple triangular support blocks 51 position and support the lock cylinder, allowing the debris inside the lock cylinder to fall out of the lock cylinder and into the sliding cylinder 61.

[0037] To increase the stability of the step-driven lock cylinder, this invention employs a downward elastic pressing method to press the lock cylinder's keyhole against the support block 51. (See reference...) Figure 2 , Figure 3 and Figure 4 Both sides of the upper end of the sliding cylinder 61 are equipped with a clamping assembly 62. The clamping assembly 62 includes a clamping spring column 621 fixedly installed on the upper end of the sliding cylinder 61. The telescopic end of the clamping spring column 621 slides into the interior of the sliding cylinder 61, and a guide block 622 is provided at the end of the clamping spring column 621. The guide block 622 has an isosceles trapezoidal structure, and a roller is provided on the lower end face of the guide block 622.

[0038] Specifically, after the drilling of the lock cylinder pin holes is completed, the pusher 32 pushes the lock cylinder forward from the fixture 31 onto the support block 51. Since the groove of the lock cylinder's keyhole faces directly downward during drilling, the triangular structure of the support block 51 supports the keyhole of the lock cylinder. When the front end of the lock cylinder moves to the corresponding position of the inclined surface of the trapezoidal structure of the guide block 622, the lock cylinder pushes the guide block 622 away from the lock cylinder through the inclined surface of the guide block 622, thus not interfering with the forward movement of the lock cylinder. At the same time, under the action of the pressing spring column 621, the guide block 622 drives the roller to elastically press against the outside of the lock cylinder, so that the roller elastically presses the lock cylinder downward against the support block 51. Under the action of the roller, when the sliding cylinder 61 moves back and forth, there is rolling friction between the roller and the surface of the lock cylinder, and the friction force is small, so that the lock cylinder will not move back and forth.

[0039] It should be noted that when the clamping worktable 3 moves the lock cylinder to the front limit position, the distance between the clamping seat 31 and the rearmost support block 51 is much smaller than the length of the lock cylinder.

[0040] See Figure 3 and Figure 4 The cleaning unit includes multiple arc-shaped mounting plates 611 fixedly installed on the arc-shaped surface inside the sliding cylinder 61. A brush bristle is provided on the side of the arc-shaped mounting plate 61 closest to the center line of the sliding cylinder 61, and a chip removal hole is provided on the lower side of the sliding cylinder 61. When the sliding cylinder 61 moves back and forth, the sliding cylinder 61 drives the brush bristle pair to clean the debris on the surface of the lock cylinder through the arc-shaped mounting plate 611, and the cleaned debris can fall into the sliding cylinder 61 and fall out of the sliding cylinder 61 through the chip removal hole.

[0041] To effectively clean debris from the pin holes of the lock cylinder, this invention employs an up-and-down shaking motion of the lock cylinder to dislodge the debris, thereby preventing debris residue from remaining inside the pin holes. (See reference...) Figure 4 , Figure 5 and Figure 6 An auxiliary cleaning rod 79 is fixedly installed at the rear end of the reciprocating plate 73 and below the main cleaning rod 75. The part of the auxiliary cleaning rod 79 located inside the sliding cylinder 61 is also provided with bristles. Multiple upper blocks 751 are fixedly installed at the upper end of the main cleaning rod 75. The main cleaning rod 75 drives the lock cylinder to move up and down through the upper blocks 751, so that the auxiliary cleaning rod 79 can move up and down relative to the lock cylinder to achieve cleaning of the lock eye in the vertical direction. The shaking plate 74 is slidably connected to the reciprocating plate 73 through the return spring 741. The upright plate 71 has clearance holes corresponding to the positions of the main cleaning rod 75 and the auxiliary cleaning rod 79, and the main cleaning rod 75 and the auxiliary cleaning rod 79 are interposed in the clearance holes. The lifting block 44 is set in L shape, and the lifting block 44 is provided with an inclined surface that cooperates with the L-shaped rod 78.

[0042] Specifically, when the lock cylinder support platform 5 moves the lock cylinder to the right and the L-shaped rod 78 moves to the corresponding position on the inclined surface of the lifting block 44, the inclined surface of the lifting block 44 pushes the L-shaped rod 78 to move the shaking plate 74 upward and compress the return spring 741, so that the main cleaning rod 75 can move the lock cylinder upward through the upper top block 751. When the L-shaped rod 78 and the inclined surface of the lifting block 44 separate, under the action of the return spring 741, the shaking plate 74 drives the main cleaning rod 75 to quickly return to the initial position downward. Since the guide block 622 is always elastically pressed against the upper side of the lock cylinder, the lock cylinder quickly returns to the initial position downward under the elastic action of the pressing spring column 621, thereby realizing continuous up and down shaking of the lock cylinder. At the same time, since the auxiliary cleaning rod 79 only moves back and forth with the reciprocating plate 73, when the lock cylinder is shaken up and down, the auxiliary cleaning rod 79 moves up and down relative to the lock cylinder.

[0043] To prevent residual debris on the bristles of the main cleaning rod 75 and the auxiliary cleaning rod 79 from affecting subsequent debris cleaning of the lock cylinder, this invention employs a method of cleaning the bristles of the main cleaning rod 75 and the auxiliary cleaning rod 79 to reduce the amount of residual debris on the bristles of the main cleaning rod 75 and the auxiliary cleaning rod 79; see reference. Figure 3 , Figure 5 , Figure 6 and Figure 7A toggle plate 45 is fixedly installed on the upper inner wall of the U-shaped frame 42 below. Both the toggle block 43 and the toggle plate 45 are provided with inclined surfaces that cooperate with the mating block 77. The rear end of the upright plate 71 is fixedly installed with an installation ring 711 by two vertically arranged connecting rods. Two cleaning plates 712 arranged horizontally are fixedly installed at the rear end of the installation ring 711. A cleaning plate 713 with an elastic telescopic structure is fixedly installed on the upper side of the rear end of the installation ring 711. The two cleaning plates 712 and 713 are arranged backwards and pointed on opposite sides, and the two cleaning plates 712 and 713 are also arranged in a comb-like shape on opposite sides.

[0044] Specifically, when the lock cylinder support platform 5 moves the lock cylinder to the right and the mating block 77 moves to the corresponding position of the inclined surface of the actuating block 43, the inclined surface of the actuating block 43 pushes the mating block 77 to move the reciprocating plate 73 forward and compresses the elastic return rod 72. When the mating block 77 and the actuating block 43 separate, the reciprocating plate 73 moves backward to the initial position under the action of the elastic return rod 72, so as to realize the forward and backward movement of the reciprocating plate 73. During this process, the main cleaning rod 75 and the auxiliary cleaning rod 79 move back and forth relative to the first cleaning plate 712 and the second cleaning plate 713, so that the comb-like shape of the first cleaning plate 712 and the second cleaning plate 713 cleans the debris remaining on the second brush. Since the pin hole of the lock cylinder is located in front of it, that is, the part of the second brush where the main cleaning rod 75 and the auxiliary cleaning rod 79 are located in front is more likely to retain more debris, thereby preventing the second brush located in front from retaining too much debris and affecting the cleaning effect on the lock cylinder keyhole.

[0045] Because the elastic telescopic end of the cleaning plate 713 continuously presses against the upper surface of the main cleaning rod 75, and the cleaning plate 713 is tilted, the upper top block 751 can compress the elastic telescopic end of the cleaning plate 713, thus preventing interference with the forward and backward movement of the main cleaning rod 75.

[0046] When the chain plate 41 moves to the lower part of the chain conveyor 4 and drives the mating block 77 to move to the left to the corresponding position of the inclined surface of the actuating plate 45, the unloading of the lock cylinder is completed. As the chain plate 41 continues to move, the inclined surface of the actuating plate 45 pushes the mating block 77 to drive the reciprocating plate 73 to move forward continuously, so that the cleaning plate 1 712 and the cleaning plate 2 713 thoroughly clean the debris remaining on the brush bristles of the main cleaning rod 75 and the auxiliary cleaning rod 79.

[0047] For automatic unloading of the lock cylinder after debris removal, please refer to... Figure 1 and Figure 5In this invention, an elastic push rod 731 is installed through and slidably on a reciprocating plate 73. The rear end of the elastic push rod 731 slides through the upright plate 71 and is fixedly installed with a push plate 732. An active component 11 is installed on the upper right side of the base 1. The active component 11 drives the push plate 732 corresponding to its position to push the lock cylinder backward through the elastic push rod 731. In this invention, the active component 11 uses an electric push rod to push the elastic push rod 731 corresponding to its position to move backward.

[0048] When the chain plate 41 moves the corresponding lock cylinder to the right to the position corresponding to the driving member 11, the driving member 11 is activated to move the elastic push rod 731 corresponding to its position backward, so that the elastic push rod 731 moves the push plate 732 backward, so that the push plate 732 can automatically push the lock cylinder backward from the support block 51.
