Description

Technical Field

[0001] The present invention relates to the technical field of lock body processing, and in particular to an automation device for lock body milling processing and a control method thereof. Background Art

[0002] The fully automatic lock body, also known as the electronic lock body or the mechatronic lock body, belongs to the category of smart locks. During the production process, the end face of the lock body needs to be processed and fine-milled to make the surface of the end face of the lock body smooth and burr-free, which helps to improve the performance and life of the lock. In the prior art, the staff drives the crank to rotate by winding the screw rod, so that the screw rod moves along the bearing block, and then uses the movable splint and the fixed splint to clamp the workpiece.

[0003] However, in the actual operation process, after clamping the workpiece, it is necessary to move the workpiece under the milling cutter. However, in the process of moving, the movable clamp may cause the workpiece to loosen due to the shaking generated during the movement, thereby affecting the final precision milling accuracy of the workpiece. At the same time, when the milling cutter encounters a difficult-to-mill part on the lock body, the milling cutter applies force to the lock body, and the lock body slips, so that the preset path of the milling cutter acts on the lock body. There will be deviations, and there is no mechanism to automatically correct the slip, which can easily affect the accuracy of the milling processing of the lock body by the milling cutter, and when the lock body slips, the machine must be stopped to correct the position of the lock body. At this time, it is not only easy to affect the progress of the lock body processing, but also the lock body needs to be repositioned, increasing the workload of the staff.

[0004] Therefore, an automated device for lock body milling and a control method thereof are invented to solve the above problems. Summary of the invention

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] In the prior art, during the process of clamping and fixing the lock body during milling, the lock body is generally fixed by manually rotating bolts. This fixing method is not only easy to cause damage to the lock body, but also not conducive to the rapid loading and unloading of the lock body, and easily increases the workload of the staff. Therefore, this embodiment is specially invented to solve the above problems.

[0041] like Figure 1 to Figure 2 As shown, this embodiment provides an automated device for lock body milling processing, including a bed 1, a support plate 2 is slidably connected to the bed, a clamping mechanism 3 is arranged on the support plate 2, the clamping mechanism 3 includes a force-bearing plate 301 fixedly connected to the support plate 2, a clamping plate 302 is slidably connected to the force-bearing plate 301, two cylinders 305 distributed along the length direction of the force-bearing plate 301 are installed on the support plate 2, the output end of the cylinder 305 is fixedly connected to the clamping plate 302, the shape of the force-bearing plate 301 is L-shaped, and a buffer layer 306 is fixedly connected to the side of the force-bearing plate 301 close to the clamping plate 302.

[0042] The bed body 1 is provided with a displacement assembly 6 located at the lower side of the support plate 2, the bed body 1 is fixedly connected with a support frame 7, the support frame 7 is provided with a translation assembly 8, one side of the translation assembly 8 is installed with a lifting assembly 10 through a connecting block 9, and the lifting assembly 10 is installed with a milling cutter assembly 11.

[0043] In actual use, the lock body to be processed is first placed on the force-bearing plate 301, and then the clamping plate 302 is driven to slide by the cylinder 305. The shape of the force-bearing plate 301 is L-shaped, which is convenient for clamping and fixing the lock body through the clamping plate 302 and the force-bearing plate 301. The structures, connection methods and control systems of the displacement component 6, the translation component 8, the lifting component 10, the milling cutter component 11 and the cylinder 305 are all existing technologies. The specific connection method and structure are no longer repeated. A buffer layer 306 is fixedly connected to the force-bearing plate 301, which can protect the lock body to a certain extent. At this time, the milling cutter component 11 is brought into contact with the lock body according to a preset path for milling processing. After the lock body is processed, the cylinder 305 is controlled to drive the clamping plate 302 to no longer clamp the lock body, and the lock body can be removed from the force-bearing plate 301.

[0044] Embodiment 2

[0045] During actual use, it was found that when the milling cutter encounters a difficult-to-mill part on the lock body, the milling cutter applies force to the lock body, which causes the lock body to slip, resulting in deviations in the preset path of the milling cutter acting on the lock body. In addition, there is no mechanism for automatically correcting the slippage, which can easily affect the accuracy of the milling processing of the lock body by the milling cutter, and when the lock body slips, the machine must be stopped to correct the position of the lock body. This not only easily affects the progress of the lock body processing, but also requires the lock body to be repositioned, increasing the workload of the staff. Therefore, further improvements are made based on the above-mentioned embodiments.

[0046] like Figures 2 to 6As shown, the adjusting mechanism 4 is arranged on the clamping plate 302, and the adjusting mechanism includes two clamping blocks 401 fixedly connected to the clamping plate 302, and the adjusting block 402 is slidably connected to the clamping block 401, and a plurality of fixing plates 403 are fixedly connected to the side of the adjusting block 402 close to the clamping plate 302. When one adjusting block 402 slides, the other adjusting block 402 slides in the opposite direction to adjust the position of the clamped lock body. The adjusting mechanism 4 also includes a guide groove 404 opened on the fixing plate 403, and a plurality of piston cylinders 405 corresponding to the fixing plates 403 are fixedly connected in the clamping block 401, and a piston rod 406 is slidably connected in the piston cylinder 405, and the end of the piston rod 406 close to the adjusting block 402 is slidably connected to the corresponding guide groove 404 through a push rod 407.

[0047] A conduit 408 is commonly connected between the two clamping blocks 401, and both ends of the conduit 408 are closed. One end of the piston cylinder 405 close to the clamping plate 302 is connected to the conduit 408 through a connecting tube 409. A slide groove 303 with an opening toward the force-bearing plate 301 is provided on the clamping plate 302. The adjusting block 402 is located in the slide groove 303 on its corresponding side, and the opposite ends of the two adjusting blocks 402 are connected to the side wall of the slide groove 303 through a second elastic member 304.

[0048] In actual use, when the milling cutter assembly 11 drives the lock body to slide, the lock body drives one of the adjustment blocks 402 to slide along the slide groove 303, and the other adjustment block 402 contacts the side wall of the slide groove 303 and does not slide, the second elastic member 304 is compressed, and the adjustment block 402 drives the fixed plate 403 to slide along the clamping block 401. Since the guide groove 404 is an inclined groove, the fixed plate 403 drives multiple piston rods 406 to slide in a direction away from the adjustment block 402 through the guide groove 404 and the push rod 407, so that the piston rod 406 pushes the gas in the piston cylinder 405 through the conduit 408 and the connecting pipe 409 into the piston cylinder 405 in the other adjustment block 402. The provision of multiple fixed plates 403, guide grooves 404, push rods 407 and piston rods 406 can increase the sliding force of the adjustment block 402, thereby increasing the amount of gas injected into the other group of piston cylinders 405.

[0049] When the gas in the other group of piston cylinders 405 increases, the gas pushes the piston rod 406 to slide along the piston cylinder 405 in the direction close to the adjusting block 402. At this time, the piston rod 406 drives the other adjusting block 402 to slide along the sliding groove 303 through the push rod 407, the guide groove 404 and the fixing plate 403. The second elastic member 304 is compressed, causing the other adjusting block 402 to slide in the opposite direction of the sliding of the lock body. At this time, under the action of the friction between the adjusting block 402 and the lock body, the other adjusting block 402 drives the lock body to slide in the opposite direction of the sliding, so that the adjusting block 402 drives the lock body to correct and adjust the sliding distance, and the adjusting block 402 dynamically corrects the position of the lock body, thereby ensuring that the milling cutter assembly 11 can mill the lock body more accurately, and when the resistance to the milling cutter assembly 11 returns to normal, under the action of the second elastic member 304, the opposite surfaces of the two adjusting blocks 402 are in contact with the side walls of the sliding groove 303 on the corresponding side.

[0050] To summarize, by providing the adjusting block 402, the fixing plate 403, the guide groove 404, the piston cylinder 405, the piston rod 406 and the push rod 407, when the lock body drives one of the adjusting blocks 402 to slide, the sliding force of the adjusting block 402 can be amplified under the action of the multiple fixing plates 403, the piston cylinder 405 and the piston rod 406, so that the amplified force is converted into the sliding force of another group of piston rods 406 through the piston cylinder 405, the connecting tube 409 and the guide tube 408, so that the other adjusting block 402 drives the lock body to slide in the opposite direction of the sliding, and during the milling process of the lock body by the milling cutter assembly 11, the lock body can be automatically and dynamically corrected when it slips, thereby ensuring the accuracy of the milling process of the lock body, while avoiding the problem of stopping the machine to adjust the position of the lock body, thereby reducing the workload of the staff.

[0051] Embodiment 3

[0052] During the above-mentioned use, since the friction force between the adjustment block 402 and the lock body is at a constant value, when the lock body slips, when the other adjustment block 402 drives the lock body to reset, the lock body is not pre-tightened again, resulting in poor effect of the lock body sliding reset. Therefore, further improvements are made based on the above-mentioned embodiment.

[0053] like Figures 3 to 7 As shown, the pre-tensioning mechanism 5 includes a pre-tensioning block 501 slidably connected to the clamping block 401. The two pre-tensioning blocks 501 can slide relative to or away from each other along the clamping block 401 under the action of the adjusting mechanism 4. Slide blocks 502 are fixedly connected at both ends of the pre-tensioning block 501. A first elastic member 503 is connected between the slide block 502 and the adjusting block 402. The end of the piston rod 406 close to the adjusting block 402 can contact the corresponding pre-tensioning block 501. The side of the pre-tensioning block 501 close to the force plate 301 is fixedly connected to an anti-slip layer 504, and the guide groove 404 is an inclined groove.

[0054] In actual use, when the milling cutter assembly 11 drives the lock body to slide, the lock body drives one of the adjustment blocks 402 to slide along the slide groove 303, and the other adjustment block 402 contacts the side wall of the slide groove 303 and does not slide. The second elastic member 304 is compressed, and the adjustment block 402 drives the fixed plate 403 to slide along the clamping block 401, so that the fixed plate 403 drives multiple piston rods 406 to slide away from the adjustment block 402 through the guide groove 404 and the push rod 407. At this time, the piston rod 406 no longer squeezes the pre-tightening block 501. Under the action of the first elastic member 503, the first elastic member 503 drives the pre-tightening block 501 to slide along the adjustment block 402 through the slider 502, and the friction between the pre-tightening block 501 and the lock body is reduced.

[0055] When the gas in the other group of piston cylinders 405 increases, the gas pushes the piston rod 406 to slide along the piston cylinder 405 in the direction close to the adjusting block 402. At this time, the piston rod 406 drives the other adjusting block 402 to slide along the sliding groove 303 through the push rod 407, the guide groove 404 and the fixing plate 403. The second elastic member 304 is compressed. At this time, the other group of piston rods 406 pushes the other pre-tightening block 501 to slide in the direction close to the lock body, so that the other pre-tightening block 501 increases the friction between the lock body, the first elastic member 503 is compressed, and the anti-slip layer 504 provided can better increase the friction between the pre-tightening block 501 and the lock body. At this time, the adjusting block 402 better drives the lock body to slide and reset, so that during the milling process, the lock body is better driven to be in a constant processing position through the adjusting block 402, thereby ensuring the accuracy of the milling process of the lock body.

[0056] To summarize, through the arrangement of the pre-tightening block 501, the first elastic member 503 and the slider 502, and under the coordinated action of multiple piston rods 406, and when the lock body drives one of the adjustment blocks 402 to slide, the friction between the pre-tightening block 501 and one of the adjustment blocks 402 is reduced, and at the same time, the friction between the other pre-tightening block 501 and the other adjustment block 402 is increased, so that one of the pre-tightening blocks 501 pre-tightens the lock body, making it easier for one of the adjustment blocks 402 to better drive the lock body to slide in the opposite direction of the sliding, thereby enhancing the effect of the adjustment block 402 driving the lock body to correct its position, and also improving the effect of dynamic correction, so as to ensure the milling processing accuracy of the lock body.

[0057] Embodiment 4

[0058] This embodiment also provides a control method for an automated device for lock body milling, comprising the following steps:

[0059] S1: First, place the lock body to be processed on the force-bearing plate 301, then control the cylinder 305 to drive the clamping plate 302 to slide and contact the lock body, and fix the lock body between the force-bearing plate 301 and the clamping plate 302;

[0060] S2: Then, the displacement assembly 6, the translation assembly 8 and the lifting assembly 10 are controlled to drive the support plate 2 and the milling cutter assembly 11 to move according to a preset path, so that the milling cutter assembly 11 performs milling processing on the lock body according to the preset path;

[0061] S3: When the milling cutter assembly 11 drives the lock body to slide, the milling cutter assembly 11 drives the lock body to slide in one direction, so that the lock body drives one adjustment block 402 to slide along the clamping block 401. At this time, under the action of the adjustment mechanism 4, the other adjustment block 402 slides in the opposite direction;

[0062] S4: At the same time, the pre-tightening block 501 on the adjusting block 402 with greater force slides to reduce the friction with the lock body, and the pre-tightening block 501 on the adjusting block 402 with less force increases the friction with the lock body, thereby dynamically correcting the slippage of the lock body.

[0063] S5: After the lock body is finally processed, the milling cutter assembly 11 is separated from the lock body and no longer operates, and then the clamping plate 302 is driven by the cylinder 305 to slide and no longer clamp the lock body, and the lock body after the milling process is removed.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.

A control method for an automated device for milling a lock body, applied to the automated device for milling a lock body according to claim 9, characterized in that: The following steps are involved: S1: firstly, placing the lock body to be processed on the force-bearing plate (301), then controlling the cylinder (305) to drive the clamping plate (302) to slide and contact the lock body, and fixing the lock body between the force-bearing plate (301) and the clamping plate (302); S2: Then, the displacement assembly (6), the translation assembly (8) and the lifting assembly (10) are controlled to drive the support plate (2) and the milling cutter assembly (11) to move along a preset path, so that the milling cutter assembly (11) performs milling processing on the lock body along the preset path; S3: When the milling cutter assembly (11) drives the lock body to slide, the milling cutter assembly (11) drives the lock body to slide in one direction, so that the lock body drives one of the adjustment blocks (402) to slide along the clamping block (401), and at this time, under the action of the adjustment mechanism (4), the other adjustment block (402) slides in the opposite direction; S4: At the same time, the pre-tightening block (501) on the adjusting block (402) subjected to greater force slides to reduce the friction force with the lock body, and the pre-tightening block (501) on the adjusting block (402) subjected to less force increases the friction force with the lock body, thereby dynamically correcting the slippage of the lock body; S5: After the lock body is finally processed, the milling cutter assembly (11) is separated from the lock body and no longer operates, and then the clamping plate (302) is driven by the cylinder (305) to slide and no longer clamp the lock body, and the lock body after the milling process is removed.
