Description

Technical Field

[0001] This utility model relates to the field of insertion machine technology, and in particular to an anti-misinsertion structure for insertion machines. Background Technology

[0002] In the field of insertion machine technology, the accuracy and efficiency of insertion have always been key performance indicators. Traditional insertion machines often suffer from insufficient accuracy, low efficiency, and susceptibility to incorrect insertion during the insertion process, which seriously affects the production quality and efficiency of the insertion machine.

[0003] Specifically, traditional insertion machines typically rely on manual operation or simple mechanical structures to adjust the insertion position, making it difficult to precisely control the insertion accuracy. Furthermore, due to the lack of effective monitoring and buffering mechanisms, abnormal resistance or misalignment of the insertion component often goes undetected and the machine cannot be stopped in time, leading to incorrect insertion. In addition, the flexibility and reliability of the clamping components in traditional insertion machines need improvement to accommodate insertions of different sizes and shapes.

[0004] To solve the above problems, this utility model provides a structure for preventing incorrect insertion in a plug-in machine. Utility Model Content

It has high practical value and application prospects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-misinsertion structure for a plug-in machine includes a movable crossbeam, a horizontal adjustment mechanism is provided on the surface of the movable crossbeam, an electric telescopic rod is provided on the surface of the horizontal adjustment mechanism, a drive box is fixedly connected to the telescopic end of the electric telescopic rod, a positioning turntable is rotatably provided on the lower surface of the drive box, and an insertion mechanism is fixedly provided on the lower surface of the positioning turntable.

[0008] The insertion mechanism includes a limiting circular shell fixedly installed on the lower surface of the positioning turntable. A limiting movable column is slidably provided on the inner wall of the limiting circular shell. A clamping assembly is fixedly connected to the bottom end of the limiting movable column. A pressure sensor is fixedly provided on the inner top wall of the limiting circular shell. Two limiting guide rods are symmetrically arranged on the inner wall of the limiting circular shell. A buffer spring is sleeved on the surface of the limiting guide rod.

[0009] In a preferred embodiment, two symmetrically positioned limiting sliders are fixedly installed on the top of the limiting movable column. The surface of the limiting slider is provided with a limiting through hole that matches the limiting guide rod. The limiting slider and the limiting through hole are slidably connected to the surface of the limiting guide rod.

[0010] In a preferred embodiment, the bottom end of the buffer spring is fixedly connected to the upper surface of the limiting slider, and the top end of the buffer spring is fixedly connected to the inner top wall of the limiting circular shell. A movable top block is fixedly provided at the top end of the limiting movable column, and the position of the movable top block corresponds to the pressure sensor.

[0011] In a preferred embodiment, the clamping assembly includes a clamping seat fixed to the bottom end of the limiting movable column. The lower surface of the clamping seat has two symmetrically formed strip-shaped mounting grooves. The inner wall of the strip-shaped mounting groove is rotatably connected to a bidirectional lead screw. The surface of the bidirectional lead screw is threadedly connected to two moving blocks. The bottom end of the moving blocks is fixedly provided with a clamping plate.

[0012] In a preferred embodiment, rubber anti-slip pads are fixedly provided on the opposing surfaces of the two clamping plates. A rectangular groove is provided inside the clamping seat, and a clamping motor is fixed on the inner wall of the rectangular groove. A first worm is fixed on the rotating shaft of the clamping motor, and a first worm wheel is fixed on the surface of the bidirectional lead screw. The first worm meshes with the first worm wheel.

[0013] In a preferred embodiment, an adjusting motor is fixedly mounted on the surface of the drive box, the rotating shaft of the adjusting motor extends into the interior of the drive box and is fixedly connected to a second worm gear, the inner wall of the drive box is rotatably connected to an adjusting shaft, the surface of the adjusting shaft is fixedly mounted with a second worm wheel, the second worm gear meshes with the second worm wheel, and the bottom end of the adjusting shaft is fixedly connected to the center of the upper surface of the positioning turntable.

[0014] In a preferred embodiment, the horizontal adjustment mechanism includes a movable lead screw rotatably connected to the inner side of the movable crossbar, a movable seat being threaded onto the surface of the movable lead screw, a fixed frame being fixedly mounted on the surface of the movable seat, and the top end of the electric telescopic rod being fixedly mounted on the lower surface of the fixed frame.

The telescopic function of the electric telescopic rod, combined with the rotation of the positioning turntable, allows the insertion mechanism to flexibly reach the designated position, greatly improving the precision and efficiency of insertion.

[0018] Secondly, the design enhances the anti-misalignment capability. The internal limit posts, pressure sensors, and buffer springs of the insertion mechanism effectively ensure stability and accuracy during the insertion process.

Driven by the clamping motor, it can achieve fast and precise opening and closing of the clamping plate, which is suitable for plugs of different sizes and shapes. At the same time, the addition of rubber anti-slip pads further improves the stability and reliability of clamping. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1 to 4 A mis-insertion prevention structure for a plug-in machine mainly includes a movable crossbeam 1, a horizontal adjustment mechanism 2, an electric telescopic rod 3, a drive box 4, a positioning turntable 5, an insertion mechanism 6, a clamping assembly 7, and an adjustment motor 8, among other core components. These components, through precise mechanical design and electrical control, collectively achieve the plug-in machine's high precision, high efficiency, and mis-insertion prevention function.

[0030] It is worth noting that the movable crossbeam 1, as the supporting foundation of the entire insertion machine's anti-misinsertion structure, is designed to be stable and rigid enough to withstand the weight of each component and the dynamic load generated by its movement during operation. The length and width of the movable crossbeam 1 are customized according to actual needs to adapt to insertion operations of different scales.

[0031] It is worth noting that the horizontal adjustment mechanism 2 is located on the surface of the movable crossbeam 1, and its main function is to enable precise horizontal movement of the insertion mechanism 6. The horizontal adjustment mechanism 2 includes a movable lead screw 201 rotatably connected to the inside of the movable crossbeam 1, a movable seat 202 threadedly connected to the movable lead screw 201, and a fixed frame 203 fixed to the surface of the movable seat 202. The top end of the electric telescopic rod 3 is fixedly installed on the lower surface of the fixed frame 203, thus forming a stable support structure.

[0032] One end of the movable lead screw 201 is connected to the rotating shaft of the drive motor 204, which is fixed to the end of the movable crossbeam 1. When the drive motor 204 starts, its rotating shaft drives the movable lead screw 201 to rotate, thereby driving the movable base 202 and its components, such as the fixed frame 203 and the electric telescopic rod 3, to move horizontally along the axial direction of the movable lead screw 201. This design is not only simple in structure but also enables precise displacement control, meeting the positional accuracy requirements of insertion operations.

[0033] The electric telescopic rod 3, as the vertical driving component, has its telescopic end fixedly connected to the drive box 4. The telescopic movement of the electric telescopic rod 3 drives the drive box 4 and its lower components, such as the positioning turntable 5 and the insertion mechanism 6, to perform vertical lifting and lowering movements. The selection of the electric telescopic rod 3 must consider parameters such as its stroke, speed, and load capacity to ensure it meets the actual needs of the insertion operation.

[0034] The drive box 4 has a box-shaped structure and an internal transmission mechanism to drive the rotation of the positioning turntable 5. Specifically, an adjustment motor 8 is fixedly mounted on the surface of the drive box 4, and the rotating shaft of the adjustment motor 8 extends into the interior of the drive box 4 and is fixedly connected to a second worm gear 9. An adjustment shaft 10 is rotatably connected to the inner wall of the drive box 4, and a second worm wheel 11 is fixedly mounted on the surface of the adjustment shaft 10. The second worm gear 9 meshes with the second worm wheel 11. When the adjustment motor 8 is started, its rotating shaft drives the second worm gear 9 to rotate, which in turn drives the adjustment shaft 10 and the positioning turntable 5 to rotate through the worm gear transmission. This design is not only compact but also has high transmission efficiency, enabling precise angle control.

[0035] The positioning turntable 5 is fixedly mounted on the lower surface of the drive box 4, and its surface is equipped with an insertion mechanism 6. The rotation function of the positioning turntable 5 allows the insertion mechanism 6 to be adjusted at any angle in the horizontal plane to adapt to the needs of different insertion positions. The material of the positioning turntable 5 must have a certain degree of rigidity and wear resistance to ensure its long-term stability and reliability.

[0036] It is worth noting that the insertion mechanism 6 is one of the core components of this utility model, and its structure is complex and its functions are diverse. The insertion mechanism 6 includes a limiting circular shell 601 fixedly installed on the lower surface of the positioning turntable 5, a limiting movable column 602 slidably disposed on the inner wall of the limiting circular shell 601, and a clamping assembly 7 fixedly connected to the bottom end of the limiting movable column 602.

[0037] A pressure sensor 603 is fixedly installed on the inner top wall of the limiting shell 601 to monitor pressure changes during the insertion process in real time. Two limiting guide rods 604 are symmetrically arranged on the inner wall of the limiting shell 601, and a buffer spring 605 is sleeved on the surface of each limiting guide rod 604. Two symmetrically positioned limiting sliders 606 are fixedly installed on the top of the limiting movable column 602, and the surface of each limiting slider 606 has limiting through holes that match the limiting guide rods 604. Through this design, the limiting movable column 602 can perform stable sliding movement under the guidance of the limiting guide rods 604, while the buffer springs 605 provide appropriate cushioning to protect the insertion from damage.

[0038] A movable top block 607 is also fixedly installed at the top of the limiting movable column 602, and the position of the movable top block 607 corresponds to that of the pressure sensor 603. When the insert is subjected to abnormal resistance or misalignment, the movable top block 607 will press the pressure sensor 603, thereby triggering an alarm or shutdown mechanism to prevent misinsertion.

[0039] It is worth noting that the clamping assembly 7 is an important component of the insertion mechanism 6, and its main function is to provide stable and reliable clamping for the insertion. The clamping assembly 7 includes a clamping seat 701 fixed to the bottom end of the limiting movable column 602, a strip-shaped mounting groove 702 symmetrically formed on the lower surface of the clamping seat 701, a bidirectional lead screw 703 rotatably connected to the inner wall of the strip-shaped mounting groove 702, and two moving blocks 704 threadedly connected to the surface of the bidirectional lead screw 703. A clamping plate 705 is fixedly provided at the bottom end of the moving block 704 for directly clamping the insertion.

[0040] The working principle of the clamping assembly 7 relies on the coordinated movement of the bidirectional lead screw 703 and the moving blocks 704. A rectangular slot is formed inside the clamping base 701, and a clamping motor 707 is fixed to the inner wall of the rectangular slot. A first worm gear 708 is fixed to the rotating shaft of the clamping motor 707, and a first worm wheel 709 is fixed to the surface of the bidirectional lead screw 703. The first worm gear 708 meshes with the first worm wheel 709. When the clamping motor 707 starts, its rotating shaft drives the first worm gear 708 to rotate, which in turn drives the bidirectional lead screw 703 to rotate through the worm gear transmission. Since the threads of the bidirectional lead screw 703 are opposite, when the bidirectional lead screw 703 rotates, the two moving blocks 704 will move towards or away from each other along the strip mounting groove 702, thereby achieving rapid and precise opening and closing of the clamping plate 705.

[0041] Furthermore, it should be noted that rubber anti-slip pads 706 are fixedly provided on the opposite surfaces of both clamping plates 705 to increase the friction between the clamping plates 705 and the plug-in, preventing the plug-in from sliding or falling off during clamping. The rubber anti-slip pads 706 must be made of a material with certain elasticity and wear resistance to ensure their long-term stability and reliability.

[0042] Working principle: In use, first adjust the horizontal position of the insertion mechanism 6 by adjusting the horizontal adjustment mechanism 2 so that it is aligned with the position to be inserted. Then start the electric telescopic rod 3 to drive the drive box 4 and its lower positioning turntable 5, insertion mechanism 6 and other components to move vertically up and down, so that the clamping plate 705 of the clamping assembly 7 can accurately clamp the insertion.

[0043] During the clamping process, the clamping motor 707 starts, driving the bidirectional lead screw 703 to rotate via a worm gear transmission. This causes the two moving blocks 704 and the clamping plate 705 to move towards each other until the clamping plate 705 tightly clamps the plug. At this time, the pressure sensor 603 monitors the pressure changes in real time during the clamping process to ensure that the clamping force is moderate and stable.

[0044] After the insert is clamped, the regulating motor 8 is started, driving the positioning turntable 5 to rotate via a worm gear transmission, allowing the insert mechanism 6 to flexibly adjust the angle and direction of the insert. Then, the electric telescopic rod 3 is started again to accurately deliver the insert into the designated slot or welding position.

[0045] During the insertion process, if abnormal resistance or misalignment is encountered, the movable top block 607 will press against the pressure sensor 603 and trigger an alarm or shutdown mechanism. At this time, the operator can immediately stop the machine to check and troubleshoot the problem, thereby preventing misinsertion.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
