Technical Field
[0001] The utility model relates to the technical field of terminal processing equipment, in particular to a terminal slotting device. Background Art
[0002] In the production of electrical connectors, terminals are key components that connect wires to electrical components. Their quality and machining accuracy directly impact the performance and safety of the entire electrical system. Slotting the center of cylindrical terminals is a critical process in the production of electrical connectors. This requires punching a notch of a certain size in the center of the cylindrical terminal to facilitate subsequent assembly and use. Traditional cylindrical terminal slotting processes rely primarily on manual or semi-automatic equipment, which suffers from low efficiency and unstable quality and accuracy.
[0003] In recent years, although some fully automated barrel terminal slotting equipment has appeared on the market, these equipment generally have the following problems: 1. Complex structure: The internal structure of the equipment is complex, installation and debugging are difficult, and maintenance costs are high.
[0004] 2. High cost: High-end automation equipment is expensive, which is a heavy financial burden for small and medium-sized enterprises. Summary of the Invention
[0005] The purpose of the present invention is to overcome the defects of the prior art, and to provide a terminal slotting device which is simple in design, low in cost, easy to operate and can be fully automated, and is used to slot the middle part of the tubular terminal.
[0006] The technical solution of the utility model comprises a feeding channel, a punching mechanism and a turntable that performs intermittent rotation. In the circumferential direction of the turntable, feeding holes, punching holes and discharging holes are arranged in the order of rotation. Each of the above holes is provided with a placement hole for the terminal to be placed upright. An annular groove is provided at the outer edge of the turntable, and the annular groove is communicated with the placement hole. The discharge port of the feeding channel is connected with the placement hole of the feeding hole to convey the terminal to the placement hole of the feeding hole. The punching mechanism is located on one side of the punching hole, and the punching mechanism includes a punching knife, a positioning press, and a pressing tool. Block, slide and push shaft, the punch is fixed at the front end of the push shaft and moves from the rear end of the positioning pressure block to the front end of the positioning pressure block, the push shaft is set at the rear end of the positioning pressure block and moves through the rear end of the positioning pressure block, the positioning pressure block is movably set in the slide, the push shaft is set in the slide, the slide makes a reciprocating sliding action toward the punching hole position, a thrust spring is provided on the outer sleeve of the push shaft, the two ends of the thrust spring are respectively against the push shaft and the positioning pressure block to elastically push the positioning pressure block close to the punching hole position placement hole, the rear end of the positioning pressure block has a step, and the step is against the slide.
[0007] By adopting the above technical solution, from the perspective of the entire process, the discharge port of the feeding channel automatically feeds material to the placement hole of the feeding hole, and the intermittent rotation of the turntable allows the feeding, stamping and discharging processes to be carried out continuously. The stamping mechanism performs corresponding stamping on the terminal, and finally releases the terminal from the discharge hole, realizing fully automatic stamping and grooving, reducing manual intervention and improving production efficiency. The overall structural design of the equipment is simple, easy to install and debug, and has low maintenance costs, which is suitable for the economic conditions of small and medium-sized enterprises; from the perspective of the stamping process, the push shaft first acts on the thrust spring, and the thrust spring pushes the positioning pressure block close to the terminal of the stamping hole to ensure the precise positioning of the terminal before stamping. After the positioning is completed, the push shaft acts on the punch, and the punch accurately punches into the middle of the terminal under the guidance of the positioning pressure block to ensure the consistency of the slotting position and depth, thereby improving the processing accuracy and ensuring the quality of the terminal slotting.
[0008] In one possible design, the push shaft can slide movably in the slide to adjust the distance between the push shaft and the positioning pressure block. An adjusting bolt is threaded on the slide. When the adjusting bolt is tightened, its bottom presses against the push shaft to fix the position of the push shaft in the slide.
[0009] With the above design, by rotating the adjusting bolt, the position of the push shaft is adjusted to adjust the pre-tightening force of the thrust spring on the positioning block, so that the positioning block can accurately complete the positioning of the terminal before stamping, and the operating time of the positioning block can be appropriately adjusted to ensure that there is an operating time difference between the positioning block and the punching knife.
[0010] In a possible design, a bottom plate is fixedly installed at the bottom of the placement holes of the feed hole position and the punch hole position, and the bottom of the placement hole of the discharge hole position is exposed and a discharge hopper is provided below the bottom.
[0011] With the above design, the base plate provides bottom support and positioning for the terminals. The terminal positioning design is simple and effective, without the need for complex positioning devices, thus reducing equipment costs. In addition, the base plate does not extend to the discharge hole. The processed terminals fall naturally under the action of gravity and enter the discharge hopper, which simplifies the discharge process, reduces additional mechanical movements, and improves discharge efficiency.
[0012] In one possible design, a discharging column is fixedly provided on the discharging hopper, and a compression spring and a discharging pressure plate are arranged on the discharging column from top to bottom. The two ends of the compression spring are respectively pressed against the top of the discharging column and the discharging pressure plate. The discharging pressure plate extends toward the discharging hole position and is tightly pressed against the top surface of the turntable, and the discharging pressure plate acts on the rotating path between the punching hole position and the discharging hole position.
[0013] With the above design, the discharge pressure plate is subjected to the elastic force of the compression spring, which applies a downward force to the terminal in the process of transferring from the punching hole position to the discharge hole position, ensuring that the terminal can be smoothly separated from the discharge hole position and the discharge reliability is improved.
[0014] In a possible design, a semicircular groove is provided at the front end of the positioning pressing block, and the size of the semicircular groove fits the outer circle of the middle part of the terminal.
[0015] The above design ensures the precise positioning of the terminal before stamping, improves the positioning accuracy, and the shape of the semicircular groove provides uniform support for the terminal, reduces the deformation of the terminal due to uneven force during the stamping process, and improves the processing quality.
[0016] In a possible design, a driving mechanism is also included, which includes a motor, a rocker, a divider, a first connecting rod, a swing arm, a second connecting rod and a machine base. The rocker is connected to the output shaft of the motor to perform a reciprocating swinging motion; the middle part of the swing arm is hinged to the machine base, the bottom end of the swing arm is hinged to the rocker, the top end of the swing arm is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the slide; a guide rod is also fixedly installed on the machine base, and the slide is movably installed on the guide rod; one end of the first connecting rod is hinged to the rocker, and the other end of the first connecting rod is connected to the input end of the divider.
[0017] With the above design, the motor is used as the power source, and the linkage of the rocker, swing arm, connecting rod and slide seat realizes the fully automated process of terminal grooving. From feeding, stamping to discharging, the entire process does not require manual intervention, thereby improving production efficiency; and through the linkage of the first connecting rod and the swing arm, it is ensured that the reciprocating motion of the slide and the rotation action of the turntable are synchronized, so that the stamping action of the stamping mechanism and the material transfer operation of the turntable are linked, the action is executed accurately and avoids interference, thereby improving the stability and reliability of the production process.

DETAILED DESCRIPTION
[0024] like Figures 1-4 The terminal slotting equipment shown in the figure includes a feeding channel 1, a punching mechanism 2 and a turntable 3 that performs intermittent rotation. The turntable 3 is arranged with a feed hole position, a punching hole position 31 and a discharge hole position 32 in the circumferential direction according to the rotation order. Each of the aforementioned holes is provided with a placement hole 33 for the terminal to be placed upright. An annular groove 34 is provided at the outer edge of the turntable 3. The annular groove 34 is communicated with the placement hole 33 so that the middle outer surface of the terminal in the placement hole 33 can be exposed in the annular groove 34; the discharge port of the feeding channel 1 is connected with the placement hole 33 of the feeding hole position to convey the terminal to the placement hole 33 of the feeding hole position; the punching mechanism 2 is located on one side of the punching hole position 31, and the punching mechanism 2 includes a punching knife 21, a positioning pressure block 22, a slide seat 23 and a push shaft 24. 21 is fixed to the front end of the push shaft 24 and moves from the rear end of the positioning pressure block 22 to the front end of the positioning pressure block 22. The push shaft 24 is set at the rear end of the positioning pressure block 22 and movably inserted into the rear end of the positioning pressure block 22. The rear end of the positioning pressure block 22 has a rear cavity for inserting the push shaft 24. The positioning pressure block 22 is movably slidably set in the slide seat 23. The push shaft 24 is set in the slide seat 23. The slide seat 23 is driven by the driving force of the power source to make a reciprocating sliding movement toward the punching hole position 31. The push shaft 24 is covered with a thrust spring 25. The two ends of the thrust spring 25 are respectively against the push shaft 24 and the positioning pressure block 22 to elastically push the positioning pressure block 22 close to the punching hole position 31 to place the hole 33; the rear end of the positioning pressure block 22 has a step 221, which is against the slide seat 23.
[0025] The working principle is: 1. Feeding process
[0026] The discharge port of the feeding channel 1 is docked with the placement hole 33 of the feeding hole position, and the cylindrical terminal to be processed is automatically conveyed into the placement hole 33 of the feeding hole position.
[0027] The turntable 3 always rotates intermittently, bringing the terminals at the feeding hole position into the punching hole position 31 and the discharging hole position 32 in sequence.
[0028] 2. Positioning Process
[0029] When the turntable 3 brings the terminal to the punching hole 31, the push shaft 24 first acts on the push spring 25, and the push spring 25 pushes the positioning block 22 to approach the terminal of the punching hole 31, so that the positioning block 22 elastically presses the terminal slightly to determine the terminal position.
[0030] 3. Stamping process
[0031] After the positioning is completed, the push shaft 24 continues to move and acts on the punching knife 21. The punching knife 21 is accurately punched into the middle of the terminal under the guidance of the positioning pressing block 22 to form the required notch.
[0032] 4. Return process
[0033] After the stamping is completed, the slide 23 drives the push shaft 24 to return to its original position, so that the punch 21 is separated from the terminal. At this time, the positioning block 22 is still kept in position due to the action of the thrust spring 25 until the slide 23 comes into contact with the step 221, and the slide 23 pulls the positioning block 22 back to its original position.
[0034] 5. Discharging process
[0035] The turntable 3 rotates: the turntable 3 continues to rotate, bringing the stamped terminals to the discharge hole 32 and sending the terminals out of the turntable 3.
[0036] From the perspective of the entire process, the discharge port of the feed channel 1 automatically feeds material to the placement hole 33 of the feed hole. The intermittent rotation of the turntable 3 allows the feeding, stamping, and discharging processes to be carried out continuously. The stamping mechanism 2 performs the corresponding stamping action on the terminal, and finally the terminal is released from the discharge hole 32, realizing fully automatic stamping and slotting. From the perspective of the stamping process, the cooperation of the push shaft 24, the thrust spring 25, the positioning block 22, and the slide 23 creates a time difference between the positioning work of the positioning block 22 and the operation of the punch 21, thereby realizing the work step of first positioning and then stamping, thereby improving the processing quality of the terminal.
[0037] The push shaft 24 can slide movably within the slide 23, making the position of the push shaft 24 relative to the slide 23 adjustable. This in turn allows for adjustment of the spacing between the push shaft 24 and the positioning pressure block 22, effectively adjusting the preload force of the push spring 25 on the positioning pressure block 22. This allows for a time difference suitable for the positioning operation of the positioning pressure block 22, ensuring that the turntable 3 can meet the required positioning and stamping operation time during intermittent pauses. Furthermore, an adjustment bolt 26 is threaded onto the slide 23. When tightened, the bottom of the adjustment bolt 26 abuts against the push shaft 24, securing the push shaft 24 at a preset position within the slide 23 after the position is appropriately adjusted.
[0038] To simplify the bottom positioning and discharge process of the terminals, a bottom plate 35 is fixedly mounted at the bottom of the mounting holes 33 of both the feed and punch holes 31. The bottom of the mounting hole 33 of the discharge hole 32 is exposed, and a discharge hopper 41 is provided below the bottom. As the terminals pass through the feed and punch holes 31, the bottom surface of the terminals slides relative to the bottom plate 35 until the terminals pass through the discharge hole 32, at which point the bottom surface of the terminals breaks away from the bottom plate 35 and naturally falls into the discharge hopper 41 for collection.
[0039] like Figure 5 As shown, since the terminal is subjected to pressure from the positioning block 22 and the punch 21 in the placement hole 33, it may adhere to the placement hole 33 and be unable to fall naturally. Therefore, a discharge column 42 is fixedly provided on the discharge hopper 41. The discharge column 42 is covered with a compression spring 43 and a discharge pressure plate 44 from top to bottom. The two ends of the compression spring 43 respectively press against the top of the discharge column 42 and the discharge pressure plate 44. The discharge pressure plate 44 extends toward the discharge hole 32 and is elastically pressed against the top surface of the turntable 3 due to the action of the compression spring 43. The action position of the discharge pressure plate 44 is on the rotation path between the punching hole 31 and the discharge hole 32. Under the elastic force of the compression spring 43, the discharge pressure plate 44 applies a downward force to the terminal during the process of transferring from the punching hole 31 to the discharge hole 32, ensuring that the terminal can break away from the placement hole 33 and fall.
[0040] The front end of the positioning block 22 is provided with a semicircular groove 222, which is sized to fit the outer diameter of the middle portion of the terminal. When the positioning block 22 is in operation, the semicircular groove 222 wraps around the outer surface of the middle portion of the terminal, filling the portion originally exposed by the annular groove 34, preventing the terminal from deforming during the stamping process.
[0041] It also includes a driving mechanism 5, which includes a motor 51, a rocker 52, a divider 53, a first connecting rod 54, a swing arm 55, a second connecting rod 56 and a base 57. The rocker 52 is connected to the output shaft of the motor 51 to perform a reciprocating swinging motion; the middle part of the swing arm 55 is hinged to the base 57, the bottom end of the swing arm 55 is hinged to the rocker 52, the top end of the swing arm 55 is hinged to one end of the second connecting rod 56, and the other end of the second connecting rod 56 is hinged to the slide 23; a guide rod 231 is also fixedly mounted on the base 57, and the slide 23 is movably mounted on the guide rod 231; one end of the first connecting rod 54 is hinged to the rocker 52, and the other end of the first connecting rod 54 is connected to the input end of the divider 53. The motor 51 drives the rocker 52 , which drives the divider 53 and the slide 23 to produce corresponding movements through the second connecting rod 56 and the swing arm 55 , ensuring that the reciprocating motion of the slide 23 and the rotation of the turntable 3 remain synchronous.
