[0002] Lock tongues are used in box locks, which are mostly beveled structures with varied shapes. They also require processing such as blanking, drilling, and milling. Due to their beveled and curved edges, existing processing techniques often use a single-process method, requiring one machine for each process. This necessitates multiple machines to complete the process, which inevitably leads to turnover between processes, significantly increasing processing costs and making it difficult to improve processing efficiency.

Detailed Implementation
[0020] The attached figure illustrates a specific embodiment of the present invention. This embodiment includes a frame 1, with a base plate 2 fixed on the frame 1. A feeding mechanism 4, a cutting mechanism 5, a clamping mechanism, a drilling mechanism, a bevel cutting mechanism 8, and a conveying mechanism 3 are respectively mounted on the upper surface of the base plate 2. The conveying mechanism 3 is elongated and positioned in the middle of the base plate 2. The feeding mechanism 4 and the cutting mechanism 5 are located at its left end and distributed on both sides of the conveying mechanism 3. The cutting mechanism 5, the first drilling mechanism 6, the second drilling mechanism 7, and the bevel cutting mechanism 8 are arranged in a straight line and parallel to the conveying mechanism 3. The first drilling mechanism 6 and the second drilling mechanism 7 have identical structures. This arrangement is based on the fact that the processing sequence of the locking tongue 127 is generally feeding, cutting the flat surface, drilling, and bevel cutting. Placing the cutting surface first removes part of the material and makes subsequent bevel cutting easier. The clamping mechanism includes a first clamp 9, a second clamp 10, a third clamp 11, and a fourth clamp 12. The four clamping components are arranged in a straight line, with the straight line direction parallel to the movement direction of the material conveying mechanism 3. The four clamping components are located between the material conveying mechanism 3 and the sequentially arranged cutting mechanism 5, first drilling mechanism 6, second drilling mechanism 7, and bevel cutting mechanism 8. The first clamp 9 is close to the cutting mechanism 5, the second clamp 10 is close to the first drilling mechanism 6, the third clamp 11 is close to the second drilling mechanism 7, and the fourth clamp 12 is close to the bevel cutting mechanism 8. The unloading mechanism 4 consists of an unloading component and a feeding component. The locking tongue bar 16 is supported on the feeding front guide block 18 and the feeding rear guide block 17. When the first material conveying block 103 is at the left end, it is in the same straight line as the locking tongue bar 16. Generally, the locking tongue bar 16 is relatively long. In order to prevent the other end from drooping, a material rack 15 is often placed next to the frame 1. Rollers can be installed on the material rack 15 to facilitate the feeding of the locking tongue bar 16. The first material transport block 103 is installed at the top of the material transport transfer group at the far left. The second material transport block 104, the third material transport block 105, and the fourth material transport block 106 are installed on the material transport slide plate 108 at the far bottom. The material transport slide plate 108 can move back and forth relative to the material transport moving plate 98. When the material transport moving plate 98 moves to the right, it can drive the first material transport block 103, the second material transport block 104, the third material transport block 105, and the fourth material transport block 106 to move to the right by the same distance.In the initial state, with the material conveying plate 98 at the left end, the first material conveying block 103 is positioned below the cutting saw blade 32, the second material conveying block 104 is aligned with the first clamp 9, the third material conveying block 105 is aligned with the second clamp 10, and the fourth material conveying block 106 is aligned with the third clamp 11. During operation, the material conveying plate 25 moves the locking tongue bar 16, which is supported in the grooves of the pre-feeding guide block 18 and the post-feeding guide block 17, a distance equivalent to one blank block 128. Subsequently, the cutting saw blade 32 cuts out the blank block. 128 is stored in the first material conveying block 103. Simultaneously, the cutting mechanism 5 processes the two side planes of the blank block 128, the first drilling mechanism 6 processes the hole on one side of the blank block 128, the second drilling mechanism 7 processes the other side of the blank block 128, and the bevel cutting mechanism 8 processes the bevel of the locking tongue 127 and cuts off the locking tongue 127. Subsequently, the material conveying moving plate 98 moves to the right, driving the first material conveying block 103, the second material conveying block 104, the third material conveying block 105, and the fourth material conveying block 106 to move to the right. In the terminated state, the first material conveying block 103 is aligned with the first clamp 9, the second material conveying block 104 is aligned with the second clamp 10, the third material conveying block 105 is aligned with the third clamp 11, and the fourth material conveying block 106 is aligned with the fourth clamp 12. This enables the locking tongue 127 to be sequentially transferred through the first clamp 9, the second clamp 10, the third clamp 11, and the fourth clamp 12, thereby sequentially completing the unloading, cutting, drilling, and beveling processes.
[0021] The first material conveying block 103 is responsible for transferring materials between the unloading mechanism 4 and the cutting mechanism 5. The second material conveying block 104 is responsible for transferring materials between the cutting mechanism 5 and the first drilling mechanism 6. The third material conveying block 105 is responsible for transferring materials between the first drilling mechanism 6 and the second drilling mechanism 7. The fourth material conveying block 106 is responsible for transferring materials between the second drilling mechanism 7 and the bevel cutting mechanism 8. In addition, after the cutting mechanism 5 processes one of the planes of the blank block 128, the clamping rotation shaft 78 at the bottom of the first clamp 9 rotates, thereby driving the blank block 128 to rotate 180 degrees. Then the cutting blade 51 cuts down again, thereby processing the flat groove on the other side of the blank block 128.
[0022] The unloading mechanism 4 includes an unloading component and a feeding component. The unloading component is responsible for driving the rotating unloading saw blade 32 to move up and down, while the feeding component is responsible for moving the locking tongue bar 16 to a set length. The unloading spindle seat 34 is located directly above the feeding component, and an unloading spindle 33 is inserted inside it. The unloading saw blade 32 is installed at one end of the unloading spindle 33. The bolts on this end face press the unloading saw blade 32 onto the stepped surface of the unloading spindle 33. The unloading driven wheel is installed at the other end of the unloading spindle 33. This unloading driven wheel is connected to the unloading drive wheel sleeved on the unloading motor 36 through a unloading synchronous belt. The unloading motor bracket 35 has the unloading motor 36 installed at one end and is fixed to the end face of the unloading spindle seat 34 at the other end. The feeding assembly is fixed to the side of the feeding heightening seat 41. The feeding guide plate 39 has a feeding moving motor 40 at one end and a feeding small bearing seat at the other end. The feeding screw is connected to both ends of the two. When the feeding moving motor 40 rotates, it drives the feeding screw to rotate. The feeding nut seat, which is spirally connected to the feeding screw, naturally moves up and down, thereby driving the feeding moving plate 37 to descend along the feeding guide 38. When the feeding spindle 33 descends to the end position, the feeding saw blade 32 cuts the locking tongue bar material 16 and produces a blank block 128. The blank block 128 is stored in the first material conveying block 103.
[0023] The feeding assembly includes a feeding screw 30, a feeding moving plate 25, a feeding clamping seat 23, a front feeding clamping block 20, a rear feeding clamping block 21, a front feeding guide block 18, and a rear feeding guide block 17. After the locking tongue bar 16 is inserted, it is supported in the square holes of the front feeding guide block 18 and the rear feeding guide block 17, while the other end is supported by the material rack 15. The rear feeding guide block 17 engages with the rear feeding guide support plate 19, and the front feeding guide block 18 engages with the front feeding clamping block 20. The clearance groove in the middle of the front feeding clamping block 20 is used for... The material passes through the feeding sensor 24, which is used to detect whether the locking tongue bar material 16 is used up. The feeding clamping block 20 and the feeding clamping seat 23 are installed on the feeding moving plate 25. The two sets of feeding guide rails 27 installed at the lower end of the feeding moving plate 25 are fixed to the feeding raising seat 28. The feeding screw 30 is placed between the two feeding guide rails 27. The rotation of the feeding motor 31 can drive it to rotate, thereby causing the feeding screw seat 29, which is helically connected to the feeding screw 30, to move linearly, thereby generating the linear movement of the feeding moving plate 25. The feeding process is as follows: the feeding clamping cylinder 22 drives the feeding clamping block 21 to move forward, thereby clamping the locking tongue bar 16 on the front side of the feeding clamping seat 23. Then, the feeding moving plate 25 moves the locking tongue bar 16 into the inner cavity of the first material conveying block 103 under the drive of the feeding screw 30. The intermediate lower insert moves up to clamp the locking tongue bar 16. Then, the cutting saw blade 32 moves down to cut out a blank block 128. The clamping action before cutting ensures the stability of the cutting and avoids the occurrence of inaccurate blade and size. The lower end of the first material conveying block 103 is supported and connected to the block support plate 118. The lower end of the block support plate 118 is installed on the side of the material transfer clamping seat 120. The top of the material transfer clamping seat 120 is inlaid with the upper transfer insert, and the lower transfer insert slides and engages within the material transfer clamping seat 120. The cavity formed between the two is used to clamp the front end of the locking tongue bar 16. The material transfer raising seat 119 fixed on the base plate 2 has a hollow structure inside, and the end of the material transfer cylinder 121 is engaged with the lower transfer insert.
[0024] The slicing mechanism 5 includes a slicing power assembly and a slicing moving assembly. The slicing power assembly is fixed on the slicing moving plate 46. The slicing spindle 50 built into the slicing spindle seat 49 has a slicing blade 51 mounted on one end face. A slicing driven wheel is sleeved on the other end of the slicing spindle 50. The slicing driven wheel and the slicing driving wheel are connected by a slicing synchronous belt. When the slicing motor 53 rotates, it drives the slicing driven wheel to rotate, and in turn, the slicing blade 51 rotates accordingly to generate cutting power. The slicing motor frame 5... 2. One end is equipped with a cutting motor 53, and the other end is fixed to the end face of the cutting spindle seat 49. The cutting moving plate 46 is installed on four cutting sliders 45. Two cutting guide rails 44 are distributed on both sides of the cutting moving plate 46 and fixed on the cutting guide rail pad 43. The cutting screw 47 is located in the middle of the two cutting guide rails 44. The cutting feed motor 48 rotates, driving it to rotate. The cutting feed nut sleeved on it produces linear movement. Obviously, the cutting moving plate 46 will move up and down. In addition, a cutting material transfer cylinder 55 is fixed on the cutting material transfer seat 54 on the lower side of the cutting spindle seat 49. When the material conveying plate 98 is in the left start and stop state, the center of the cutting material transfer cylinder 55 coincides with the center of the blank block 128 in the first clamp 9. When the cutting blade 51 moves down to complete the cutting action, the cutting material transfer cylinder 55 extends and pushes the blank block 128 in the core seat 71 to the second material conveying block 104.
[0025] For ease of operation and debugging, all four sets of fixtures use an upper and lower clamping method. The fixture rotating seat 77 is connected to the fixture rotating shaft 78 at its lower end. Since the fixture rotating seat 77 is hollow inside, it is externally connected to the moving clamping core assembly 69. The internal clamping cylinder 75 is fixed by the clamping cylinder plate. When the clamping cylinder 75 extends, it drives the core sliding block 74 to move upward, thereby clamping the blank block 128 with the core lower insert 73 and the core upper insert 72. The fixture rotating shaft 78 is larger at one end and smaller at the other, with several rotating bearings sleeved in the middle. The rotating shell 79 is outside it, and the rotating shell fixing plate 80 is connected to it and fixedly installed on the base plate 2. Since the tail end of the fixture rotating shaft 78 is connected to the rotary motor 83, the rotary motor 83 is equipped with a reduction gear to increase torque. The end face of the rotary motor seat 81 is connected to the rotary motor 83, and the internal coupling is connected to the fixture rotating shaft 78. The rotation of the rotary motor 83 drives the core seat 71 at the upper end of the first fixture 9 to rotate. A set of material feeding components 85 are also installed on the sides of the core seat 71 of the second clamp 10 and the third clamp 11 respectively. The material feeding rod 91 installed on it is initially close to the core positioning block 76. When the second material feeding block 104 or the third material feeding block 105 approaches, the material feeding rod 91 moves forward a distance to push the blank block 128 in the fixed clamping core group 70 into the corresponding material feeding block.
[0026] The second clamp 10 and the third clamp 11 have the same structure, but they differ from the first clamp 9 and the fourth clamp 12. The fixed clamping seat 84 is directly placed on the base plate 2 and does not need to have a rotation function. The feeding assembly 85 installed on the side of the core seat 71 includes a feeding rod 91, a feeding rod guide seat 90, a feeding rod connecting block 92, a feeding horizontal plate 87, a feeding vertical plate 86, and a feeding cylinder 93. The lower end of the feeding vertical plate 86 is embedded in the groove on the side of the core seat 71, and the upper end is connected to the feeding cylinder. A horizontal plate 87 has a material-feeding guide rail 88 placed on its side. A material-feeding rod guide seat 90 is fixed to a material-feeding slider 89. One end of a material-feeding rod 91, which passes through the material-feeding rod guide seat 90, is connected to a material-feeding cylinder 93 via a material-feeding rod connecting block 92. The material-feeding cylinder 93 is fixed to a material-feeding cylinder plate 94. Material-feeding moving cylinder plates 95 and material-feeding moving limit plates 96 are also provided at both ends of the horizontal plate 87. The material-feeding moving cylinder 97 is fixed to the material-feeding moving cylinder plate 95. The main function of the material-feeding assembly 85 is to transfer the blank block 128, which is pushed into the fixed clamping core assembly 70 by the pushing cylinder 116, into the corresponding material transport block. The specific working steps are as follows: the material feeding rod 91 is initially positioned at the front end and upper end of the material feeding horizontal plate 87. This is to prevent the pneumatic drilling power head 124 from drilling into the material feeding rod 91. After the drilling is completed, the material feeding rod 91 extends downwards, and then the material feeding cylinder 93 drives the material feeding rod 91 to retract. At this time, the material conveying block approaches the core seat 71, thereby pulling the blank block 128 in the core seat 71 into the material conveying block.
[0027] Both the moving clamping core assembly 69 and the fixed clamping core assembly 70 include a core seat 71, an upper core insert 72, a lower core insert 73, a core positioning block 76, a core sliding block 74, and a clamping cylinder 75. The core seat 71 is similar to a square, with the core seats 71 on the second clamp 10 and the third clamp 11 being the same, while the core seats 71 on the first clamp 9 and the fourth clamp 12 are of a different type. The core seat 71 is a small square at one end and a large square at the other end, hollow inside, with a groove at the top for the material-pulling rod 91 to pass through. The core sliding block 74 is located inside the large square section. The lower core insert 73 is installed at one end of the core sliding block 74, and the core sliding block 74 connector embedded at the other end is connected to the clamping cylinder 75. The upper core insert 72 is fixed in the inner cavity of the small square at the upper end of the core seat 71. Two core positioning blocks 76 are also fixed on the upper side of the core seat 71, and the gap between the two core positioning blocks 76 at the middle position just avoids the material-pulling rod 91. The core seat 71 and the core insert 72 mounted on the fourth fixture 12 are slightly different from those on the second fixture 10 and the third fixture 11. The clearance groove at the upper end and the two sides have a certain slope. This clearance groove is used to pass the bevel cutting blade 63. The clearance notch of the core seat 71 mounted on the first fixture 9 is opened on its two sides. The two clearance notches are set at a 180-degree angle relative to the center of the core seat 71. When the core seat 71 rotates 180 degrees to perform face cutting, the relative position of the face cutting blade 51 relative to the blank block 128 can always be maintained.
[0028] The beveling mechanism 8 is located at the end of the process. The beveling moving plate 58 moves up and down relative to the beveling guide rail 57, driving the beveling cutter 63 to cut downwards. The fourth clamp 12 at the lower end of the beveling mechanism 8 has been pre-adjusted to a certain angle before it descends. The slot at the upper end of the core seat 71 can just avoid the descending beveling cutter 63. The beveling mechanism 8 includes a beveling power component and a beveling moving component. The bottom surface of the beveling power component is fixed to the beveling moving plate 58. A beveling spindle 62 is inserted in the beveling spindle seat 61. One end of the beveling spindle 62 is fitted with the beveling cutter 63, and the other end is fitted with the beveling driven wheel. The beveling driven wheel and the beveling driving wheel are connected by a beveling synchronous belt. One end of the beveling motor bracket 64 is connected to the beveling motor 66, and the other end is fixed to the beveling spindle seat 61. The beveling moving assembly includes a beveling guide rail 57 and a beveling moving plate 58. The beveling guide rail 57 is fixed to the side of the beveling main support 56. The beveling slider is in contact with the beveling moving plate 58. The beveling motor 66 rotates, driving the beveling main shaft 62 to rotate, thereby generating rotational power for the beveling cutter 63. A beveling screw 59 is placed between the two beveling guide rails 57 of the beveling moving assembly. The beveling moving motor 60 rotates, driving the beveling screw 59 to rotate accordingly, thereby causing the beveling screw seat to move linearly, driving the beveling moving plate 58 to move and complete the downward cutting action. A beveling unloading bracket 67 is also placed on the lower side of the beveling main shaft seat 61, on which a beveling unloading cylinder 68 is installed. After the cylinder rod extends, it pushes out the locking tongue 127 product in the core seat 71 of the fourth clamp 12, which slides down through the small hopper 13 and the large hopper 14 in sequence, and finally falls outside the frame 1.
[0029] The material conveying motor 102 is arranged on the left side of the material conveying mechanism 3, and the material conveying plate 98 is on top of it. The material conveying plate 98 is placed on four material conveying sliders. The material conveying guide rails 99 are distributed on the front and rear sides of the material conveying mechanism 3 after sliding with the material conveying sliders. One end of the material conveying screw 101 is connected to the material conveying motor 102. When the material conveying motor 102 rotates, it drives the material conveying screw 101 to rotate. The material conveying nut seat 100, which is threaded with the material conveying screw 101, drives the material conveying plate 98 to move linearly, and then drives the first material conveying block 103, the second material conveying block 104, the third material conveying block 105, and the fourth material conveying block 106 to move linearly.
[0030] The material conveying mechanism 3 includes a material conveying transfer group at the far left, comprising a material transfer and raising seat 119 mounted on a material conveying moving plate 98 and a material transfer clamping seat 120 fastened thereon. The lower end of the first material conveying block 103 is fastened and fixed to the side of the material transfer clamping seat 120. The end of the material transfer cylinder 121 inside the material transfer and raising seat 119 is fitted with a transfer joint embedded in the transfer slider. The transfer slider is slidably fitted inside the material transfer clamping seat 120. The other end of the transfer slider is inlaid with a lower transfer insert. A cavity is formed between the lower transfer insert and the upper transfer insert embedded at the top of the material transfer clamping seat 120. The cavity contains the blank block 128. The material conveying mechanism 3 has a push beam 115 mounted on the upper end of one side of the material conveying moving plate 98, with push plates 117 installed at both ends. The push plates 117 are fixed on the base plate 2. In addition, the push beam 115 is also equipped with four push cylinders 116 with their axes parallel to the base plate 2. The four push cylinders 116 are evenly distributed, and their center distance is the same as the distance between the four clamps.
[0031] The second, third, and fourth material conveying blocks 104, 105, and 106 of the material conveying mechanism 3 are supported by a material conveying slide plate 108. Slide plate guide rails 110 are placed on the lower ends of both sides of the slide plate 108. A slide plate cylinder plate 112 is fixed to the side of the material conveying moving plate 98, and the cylinder rod of the slide plate cylinder 111 mounted thereon is connected to the material conveying slide plate 108. The second and fourth material conveying blocks 104 and 106 are both hung on a block support plate 113, and the lower end of the block support plate 113 is fixed to a section extending from the material conveying moving plate 98. On the outer end of the support plate 107, the third material transport support block 105 is special. In order to achieve the purpose of rotation and turning, the lower end of the support block upright plate 113 on the side wall of the third material transport support block 105 is installed on the rotary cylinder 114. Before the material transport mechanism 3 moves left and right, the small slide cylinder 111 retracts and the material transport small slide 108 retracts. After moving into place, the material transport small slide 108 moves forward and drives the second material transport support block 104, the third material transport support block 105, and the fourth material transport support block 106 to approach the corresponding clamping assembly, preparing for the smooth transfer of the billet block 128.
