Description

Technical Field

[0001] The present application relates to a clamp and a lock punching device, belonging to the field of lock punching. Background Art

[0002] The existing padlock lock is composed of a lock beam and a lock. Most of the locks are square locks. Almost every surface of the square lock needs to be punched, such as a conventional lock beam hole, a tongue hole, a center hole, and a center hole twisting.

[0003] At present, some lock punching equipment is popular on the market, such as the punching machine with publication number: CN102091803A, which includes a frame and a bench drill installed on the frame. There are multiple bench drills, each of which includes a motor, a machine head and a clamping device. Adjacent bench drills are connected by a synchronous transmission device. One of the bench drills is provided with a lifting switch for controlling the lifting of the machine head, and the lifting switch is connected to the synchronous transmission device; the frame is also provided with a workpiece conveyor belt and a feeding device, the position of the workpiece conveyor belt is directly below the machine head and corresponds to the clamping device; the feeding device includes a movable rod and a push rod connected thereto, and the position of the push rod corresponds to the workpiece conveyor belt; the workpiece conveyor belt is divided into multiple groups, and lock flippers are arranged between adjacent workpiece conveyor belts, and there is a height difference between adjacent workpiece conveyor belts.

[0004] The device drives the push rod and the positioning assembly to move through a movable rod. The positioning assembly includes a protrusion, a cam, a rocker arm and a limit block. The protrusion is fixedly mounted on the movable rod, and the cam corresponding to the position of the protrusion is mounted on the base of the clamping device on the frame. One end of the rocker arm is connected to the cam, and the other end is connected to the tail end of the limit block. The front end position of the limit block corresponds to the workpiece conveyor belt, and the front end of the limit block can extend out of the fixed block to limit the lock workpiece A.

[0005] However, in the above technical solution, since the distance that the push rod moves each time is fixed, the positioning of locks of different sizes is different during processing, resulting in different hole positions of locks in the same batch.

[0006] Therefore, in order to solve the above technical problems, it is necessary to provide a clamp and a lock punching device to overcome the above defects in the prior art. Utility Model Content

[0007] The utility model aims to provide a lock punching device which limits the position of locks and ensures that the positions of the same batch of locks are consistent.

[0008] To achieve the above object, the technical solution adopted by the present utility model is as follows: A fixture includes a base, on which a shoulder pole for supporting the sliding of a lock is installed. On one side of the shoulder pole, there is a fixing member fixedly connected to the base and a push rod slidably connected to the base. On the other side, there is a pull rod installed on the push rod. The pull rod and the push rod are slidably connected to the base, and the sliding direction of the pull rod and the push rod is perpendicular to the length direction of the shoulder pole. The distance between the push rod and the pull rod is greater than the width of the lock block. When the push rod moves towards the fixing member, it can cooperate with the fixing member to fix the lock.

[0009] By adopting the above technical solution, when the lock moves between the pull rod and the push rod, the shoulder pole can support the lock, enabling the locks to slide in sequence. The push rod pushes the lock towards the fixing member until the lock abuts against the fixing member. The fixing member and the push rod can limit the position of the lock, thereby ensuring that the positions of the same batch of locks during processing are consistent. The pull rod can push the lock back, enabling the lock to return to the shoulder pole again. The push rod and the pull rod are fixedly connected, reducing the driving mechanism required to control the movement of the pull rod and lowering the production cost.

[0010] The fixture of the present utility model is further provided as follows: The fixing member is two L-shaped clamping blocks, and the two clamping blocks cooperate with the lock.

[0014] The fixture of the present utility model is further provided as follows: The push rod and the pull rod are two-linked by a cylinder or an oil cylinder.

[0015] By adopting the above technical solution, the oil cylinder can drive the push rod and the pull rod to achieve reciprocating motion.

[0016] The fixture of the present utility model is further provided as follows: A U-shaped rod is fixedly connected between the push rod and the pull rod, and the lock slides through the middle of the U-shaped rod.

[0017] By adopting the above technical solution, the U-shaped rod can provide a range for the movement of the lock and can connect the push rod and the pull rod.

[0018] The fixture of the present utility model is further provided as follows: A disc is fixedly connected to the side of the pull rod close to the push rod, and the disc is slidably connected between the two clamping blocks.

[0019] By adopting the above technical solution, the disc can increase the contact area with the lock.

[0020] A lock punching device of the utility model is further configured as follows: it includes a plurality of bench drills and a plurality of the clamps, the bench drills cooperate with the clamps, a feeding device is provided on one side of the plurality of clamps, the feeding device includes a movable rod and a feeding rod connected to the movable rod and corresponding to the plurality of bench drills, the length direction of the feeding rod is consistent with the length direction of a carrying pole, a lock flipper is provided between two adjacent clamps, and there is a height difference between adjacent carrying poles.

[0021] By adopting the above technical solution, the flipping mechanism and the feeding rod are started to sequentially send the lock into the fixture for fixation, and the fixture is processed by a bench drill to complete the drilling process of the lock.

[0041] Please refer to the instruction manual Figure 1 To Attachment Fig.10 As shown, the utility model is a lock punching device, as a preferred embodiment, including 5 bench drills 1, which are used to punch two lock beam holes, a tongue hole, a center hole and a center hole twisting on the lock 8 in sequence. The center hole and the center hole twisting are on the same plane, so the lock 8 needs to be punched on three surfaces, that is, the lock 8 needs to be flipped 90 degrees at least three times. The bench drill 1 includes a cylinder 11, a gear set (not shown in the figure) and a drill bit 12. The cylinder 11 drives the drill bit 12 to punch holes through the gear set. The number of bench drills 1 and cylinders 11 can be increased according to product requirements.

[0042] In this embodiment, five bench drills 1 are controlled to lift by a punching hydraulic station 13. Each bench drill 1 corresponds to a fixture 2. The fixture 2 includes a base 21. A carrying pole 22 for supporting the sliding of the lock 8 is installed on the base 21. On one side of the carrying pole 22, there is a fixing member fixedly connected to the base 21 and a push rod 23 slidably connected to the base 21. On the other side, there is a pull rod 24. A U-shaped rod 25 is fixedly connected between the push rod 23 and the pull rod 24. The lock 8 slides through the middle of the U-shaped rod 25. The U-shaped rod 25 can provide a range for the movement of the lock 8 and can connect the push rod 23 and the pull rod 24. The push rod 23 and the pull rod 24 are linked by a cylinder or an oil cylinder two 28. In this implementation, it is the oil cylinder two 28. The pull rod 24 and the push rod 23 are slidably connected to the base 21. On the side of the pull rod 24 close to the push rod 23, a disc 26 is fixedly connected. The disc 26 is slidably connected between two clamping blocks 27. The disc 26 can increase the contact area with the lock 8. The sliding directions of the pull rod 24 and the push rod 23 are perpendicular to the length direction of the carrying pole 22. The distance between the push rod 23 and the pull rod 24 is greater than the width of the lock block. When the push rod 23 moves towards the fixing member, it can cooperate with the fixing member to fix the lock 8. When the lock 8 moves between the pull rod 24 and the push rod 23, the carrying pole 22 can support the lock 8, enabling the lock 8 to slide in sequence. The push rod 23 pushes the lock 8 towards the fixing member until the lock 8 abuts against the fixing member. The fixing member is two L-shaped clamping blocks 27. The two clamping blocks 27 are respectively located on both sides of the pull rod 24. The two clamping blocks 27 cooperate with the lock 8. The two clamping blocks 27 and the push rod 23 can limit the position of the lock 8, thereby ensuring that the processing positions of the same batch of locks 8 are consistent. The clamping blocks 27 are adjustably installed on the base 21 through a bolt-nut structure 29. The bolt-nut structure 29 can adjust the distance between the clamping blocks 27 and the oil cylinder two 28. A chute 20 for adjusting the distance between the two clamping blocks 27 is also provided on the base 21. The bolt-nut structure 29 cooperates with the chute 20, enabling the clamping blocks 27 to cooperate with locks 8 of different sizes.

[0043] The pull rod 24 can push the lock 8 back, causing the lock 8 to return to the carrying pole 22 again. The push rod 23 and the pull rod 24 are fixedly connected, reducing the driving mechanism required to control the movement of the pull rod 24 and lowering the production cost.

[0044] On one side of several fixtures 2, there is a feeding device. The feeding device includes a movable rod 31 and feeding rods 32 corresponding to several bench drills 1 connected to the movable rod 31. The length direction of the feeding rods 32 is the same as the length direction of the carrying pole 22. A turning device (not shown in the figure) is provided between adjacent two fixtures 2. The turning device can turn the lock 8 over, and there is a height difference between adjacent carrying poles 22.

[0045] The movable rod 31 is connected to the feeding rod 32 through a connecting rod 33. The connecting rod 33 is provided with a through slot 34 for facilitating the sliding of the feeding rod 32. The moving range of the feeding rod 32 can be adjusted to correspond to locks 8 of different sizes. The movable rod 31 is controlled by a pushing mechanism to perform a reciprocating motion. In this embodiment, the pushing mechanism is an oil cylinder 30, which can also be an air cylinder. A controller 9 is also included, which is used to control the embossing hydraulic station 41 and the punching hydraulic station 13 to work.

[0046] In this embodiment, an embossing mechanism 4 is also included. The embossing mechanism 4 is used to emboss the lock 8. The embossing hydraulic station 41 controls the embossing mechanism 4 to work. A slide 5 is installed at the bottom of the embossing mechanism 4. The end of the slide 5 is connected to the shoulder pole 22 through a flipper. A feeding mechanism 7 is installed at the head end of the slide 5. A feeding rod 32 is installed at the connection between the feeding mechanism 7 and the slide 5. The feeding rod 32 is used to push the lock 8 toward the shoulder pole 22.

[0047] The working principle of a lock punching device and a clamp of the utility model is as follows:

[0048] A number of locks 8 to be processed are sequentially placed into the feeding mechanism 7, and the locks 8 slide along the feeding mechanism 7 to the head end of the slideway 5, and the feed rod 32 on the slideway 5 pushes the locks 8 to move in the direction of the shoulder pole 22, and at the same time, the embossing hydraulic station 41 is started to drive the embossing mechanism 4 to emboss the locks 8, and the embossed locks 8 enter the shoulder pole 22 through the flipper, and the feed rod 32 on the shoulder pole 22 pushes the locks 8 to enter between the push rod 23 and the pull rod 24, and the oil cylinder 28 is started to push the push rod 23 and the pull rod 24 to move in the direction of the clamping block 27 until the locks 8 enter. The drill bit 12 is inserted between the two clamping blocks 27 and abuts against the two clamping blocks 27. When the oil cylinder 11 is started, the drill bit 12 rotates, and the drilling hydraulic station 13 is started to control the drill bit 12 to rise and fall. After the drilling is completed, the oil cylinder 28 pushes the push rod 23 and the pull rod 24 to move toward the shoulder pole 22 until the lock 8 enters the shoulder pole 22, and the feeding rod 32 is started to push the lock 8 into the flipper for flipping, so that the flipped lock 8 enters the next shoulder pole 22, and the above process is repeated to complete the processing of the lock 82 locking beam holes, tongue holes, center holes and center hole twisting.

[0049] The above specific implementation methods are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
