Description

Technical Field

[0001] This invention relates to the field of cutting and positioning technology, specifically to a cutting and positioning device for power fittings. Background Technology

[0002] Power fittings, as key metal accessories connecting various devices in power systems, encompass various types such as suspension clamps and tension clamps. Their processing accuracy directly affects the safety of line operation. Most fittings need to withstand significant tensile forces while ensuring good electrical contact; even minor cutting deviations can lead to line faults. In fitting cutting and processing, positioning devices are the core components ensuring accuracy, but existing technologies still have many pain points that urgently need to be addressed.

[0003] Traditional positioning solutions, while simple in structure, generally suffer from insufficient adaptability: some devices can only limit the length of fittings by adjusting fixed limit blocks or lead screws, making it difficult to effectively constrain non-standard fittings of different shapes and sizes, leading to horizontal slippage or vertical runout during cutting. For example, lead screw-adjustable positioning structures can only limit the lateral ends of the fitting, resulting in significant vertical loosening during cutting, directly affecting the accuracy of the cutting edge. While high-end laser length measuring servo control systems can improve accuracy, their complexity, high cost, and high debugging threshold make them unsuitable for small and medium-sized enterprises or multi-variety, small-batch processing scenarios.

[0004] More importantly, existing devices generally lack targeted buffering and positioning coordination designs: the high-frequency vibrations generated by the high-speed rotation of the cutting disc are transmitted to the fittings through the rigid structure, causing the cutting trajectory to deviate; moreover, the buffer components are mostly designed with fixed parameters, and cannot flexibly adjust the buffering strength according to the weight and material of the fittings. Heavy fittings are easily deformed by impact, while light fittings are difficult to obtain effective vibration compensation. At the same time, positioning actions often require manual operation or external power source drive, such as manually tightening clamps or pneumatic pressurization, which not only increases the cost of manual intervention, but also has the problem of poor positioning consistency; manual marking positioning methods are even more difficult to avoid measurement errors, are inefficient, and cannot meet the needs of high-frequency processing. These problems make it difficult for existing devices to balance positioning accuracy, operational efficiency, and adaptability, and cannot meet the stringent requirements of diverse processing scenarios for power fittings.

[0005] Therefore, this invention proposes a power fitting cutting and positioning device to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a power fitting cutting and positioning device to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power fitting cutting and positioning device, comprising: a workbench and a first component mounted thereon, the first component comprising: an annular disk fixedly connected to the middle of the upper surface of the workbench, the annular disk having through holes symmetrically and vertically opened on both sides;

[0008] The first component also includes: a base disposed below the annular disk, a damper fixedly connected to the base, and an auxiliary spring body sleeved on the outer ring of the damper;

[0009] The workbench also includes a second component for positioning power fittings.

[0010] Preferably, the first component further includes: a placement base plate fixedly connected to the end of the damper away from the base, a limiting post fixedly connected to the bottom of the placement base plate, a limiting piece fixedly connected to the end of the limiting post away from the annular disk, and the limiting post being slidably inserted into the through hole.

[0011] Preferably, two sets of dampers are arranged symmetrically with the central axis of the base as the center.

[0012] Preferably, the placement substrate is positioned directly above the annular disk, the base is positioned directly below the annular disk, and two limiting posts are symmetrically arranged around the central axis of the placement substrate, with the diameter of the limiting piece being larger than that of the limiting post.

[0013] Preferably, the workbench has an inner cavity, a support frame is provided at the upper end of the workbench, a cutting disc is provided in the middle of the support frame, and the cutting disc is placed directly above the substrate.

[0014] Preferably, the second component includes: a positioning frame fixedly connected to the worktable, a symmetrical body fixedly connected to the side of the positioning frame near the substrate, a positioning rod fixedly connected to the upper end of the side of the symmetrical body perpendicular to the positioning frame, and a limit tube fixedly connected to the end of the symmetrical body away from the positioning rod.

[0015] Preferably, the positioning frame is provided in two sets and is located on both sides of the substrate. The symmetrical body is symmetrically arranged in two sets with the central axis of the positioning frame as the center. The symmetrical body is arranged in an L-shaped cross section. The limiting tube is vertically arranged above the substrate.

[0016] Preferably, the second component further includes: a curved body rotatably connected to the positioning rod, with connecting bodies rotatably connected to both sides of the curved body's bend, a synchronizing rod rotatably connected to the end of the connecting body away from the curved body, the synchronizing rod being slidably inserted into the limiting tube, the end of the synchronizing rod away from the connecting body being fixedly connected to the placement substrate, a coordinating strip being provided at the end of the curved body away from the positioning rod, a screw hole being provided in the middle of the coordinating strip, the coordinating strip being fixedly connected to the curved body by bolts engaging the screw hole, and a plurality of silicone bodies being fixedly connected to the side of the coordinating strip away from the curved body, the silicone bodies being positioned above the placement substrate.

[0017] Preferably, the bending body is in a downward bending shape, the connecting body is in a bending shape simultaneously, and the silicone body is wavy and made of rigid silicone.

[0018] Compared with the prior art, the present invention provides a power fitting cutting and positioning device, which has the following advantages:

[0019] Firstly, through the linkage structure of the second component, the positioning action is triggered by the gravity of the power fitting itself. The synergistic effect of the bending body, connecting body and synchronous rod makes the wave-shaped silicone body on the synergistic strip precisely press against the upper surface of the fitting. The upward slight tilt design of the silicone body combined with the wave pattern not only suppresses the jumping of the fitting in the vertical direction, but also restricts its sliding displacement in the horizontal direction. With the sliding limit of the limit post and through hole, it is ensured that the placement substrate is only slightly adjusted in the vertical direction. This ensures the stable posture of the fitting during the cutting process from multiple dimensions and greatly improves the cutting accuracy.

[0020] Secondly, the adjustable model in the first component can flexibly adjust the buffer strength according to the weight of the hardware, accurately absorbing the impact force applied by the cutting disc; the auxiliary spring body allows the placement of the substrate to generate a small adaptive displacement through elastic deformation, offsetting high-frequency vibration and avoiding cutting trajectory deviation caused by vibration; the synergistic effect of the two significantly reduces stress damage to the hardware, while reducing wear on device components and extending the service life of the equipment.

[0021] Third, the positioning process requires no additional power source and relies entirely on the gravity of the fittings for automatic triggering. After cutting, the auxiliary spring body achieves automatic reset, reducing manual intervention steps and improving work efficiency. The coordinating strip adjusts the initial height through multi-position screw holes, and the clamping force of the silicone body can be flexibly adjusted according to the hardness of the fittings to adapt to the positioning needs of fittings of different materials. It is easy to operate and highly adaptable.

[0022] Fourth, the components of the device adopt a symmetrical layout to ensure balanced force and avoid excessive wear on one side; the hard silicone material of the silicone body and the wave structure take into account both wear resistance and positioning effect, and the detachable design facilitates later maintenance and replacement; the combination of adjustable models and multi-level coordination strips allows it to adapt to power fittings of different weights and shapes, greatly expanding the applicability of the device and meeting the needs of diverse cutting scenarios.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] Example

[0038] Please refer to Figures 1 to 4 As shown:

[0039] To address the problems mentioned in the technical solutions, this invention provides a power fitting cutting and positioning device, comprising: a workbench 11 and a first component mounted thereon, the first component comprising: an annular disk 21 fixedly connected to the middle of the upper surface of the workbench 11, the annular disk 21 having through holes 22 symmetrically and vertically opened on both sides;

[0040] The first component also includes: a base 23 disposed below the annular disk 21, a damper 24 fixedly connected to the base 23, the damper 24 being used to buffer the stress applied by the cutting disk 14 to the power fitting during the cutting process, and an auxiliary spring 25 sleeved on the outer ring of the damper 24, the auxiliary spring 25 being used to allow the placement substrate 26 to make a small displacement in the vertical direction through its own elasticity, so as to compensate for vibration.

[0041] The workbench 11 also includes a second component for positioning power fittings.

[0042] The first component also includes: a placement base plate 26 fixedly connected to the end of the damper 24 away from the base 23, the placement base plate 26 is used to place the power fittings to be cut, a limiting post 27 is fixedly connected to the bottom of the placement base plate 26, the limiting post 27 is used to limit the movement of the placement base plate 26 in the vertical direction to avoid damage to the cutting accuracy, a limiting piece 28 is fixedly connected to the end of the limiting post 27 away from the annular disk 21, and the limiting post 27 is slidably inserted into the through hole 22.

[0043] Two sets of dampers 24 are symmetrically arranged with the central axis of the base 23 as the center.

[0044] The substrate 26 is positioned directly above the annular disk 21, and the base 23 is positioned directly below the annular disk 21. Two limiting posts 27 are symmetrically arranged around the central axis of the substrate 26, and the diameter of the limiting piece 28 is larger than that of the limiting post 27.

[0045] The workbench 11 has an inner cavity 12, and a support frame 13 is provided at the upper end of the workbench 11. A cutting disc 14 is provided in the middle of the support frame 13, and the cutting disc 14 is placed directly above the substrate 26.

[0046] A further embodiment: Please refer to Figures 5 to 8 As shown:

[0047] The second component includes: a positioning frame 31 fixedly connected to the workbench 11, a symmetrical body 32 fixedly connected to the side of the positioning frame 31 near the placement substrate 26, a positioning rod 33 fixedly connected to the upper end of the side of the symmetrical body 32 perpendicular to the positioning frame 31, and a limit tube 34 fixedly connected to the end of the symmetrical body 32 away from the positioning rod 33.

[0048] The positioning frame 31 is provided in two sets and is located on both sides of the substrate 26. The symmetrical body 32 is symmetrically arranged in two sets with the central axis of the positioning frame 31 as the center. The symmetrical body 32 is arranged in an L-shaped cross section. The limiting tube 34 is vertically arranged above the substrate 26.

[0049] The second component also includes: a curved body 35 rotatably connected to the positioning rod 33, with connecting bodies 36 rotatably connected to both sides of the bend of the curved body 35. The connecting bodies 36 move downward in coordination with the synchronizing rod 37, and the end of the connecting body 36 connected to the bend of the curved body 35 pulls the end of the curved body 35 connected to the coordinating strip 39 downward, bringing it closer to the power fittings on the placement substrate 26. The end of the connecting body 36 away from the curved body 35 is rotatably connected to the synchronizing rod 37. When the power fittings are placed on the placement substrate 26 for cutting, the gravity of the power fittings pushes the placement substrate 26 downward, thereby causing the synchronizing rod 37 to move vertically downward in coordination. The synchronizing rod 37 is slidably inserted into the limiting tube 34. The end of the bending body 37 away from the connecting body 36 is fixedly connected to the placement substrate 26. The end of the bending body 35 away from the positioning rod 33 is provided with a cooperating strip 39. A screw hole 38 is opened in the middle of the cooperating strip 39. The cooperating strip 39 is fixedly connected to the bending body 35 by bolts and screw holes 38. A plurality of silicone bodies 310 are fixedly connected to the side of the cooperating strip 39 away from the bending body 35. The silicone bodies 310 are disposed above the placement substrate 26. The silicone bodies 310 are used to move closer to the power fitting when one end of the bending body 35 is pressed down, thereby positioning the power fitting in the vertical direction to avoid vibration and displacement during the cutting process. Furthermore, its wavy shape further restricts the movement of the power fitting on the plane.

[0050] The curved body 35 is bent downwards, the connecting body 36 is also bent, the silicone body 310 is wavy and made of hard silicone, and the silicone body 310 is slightly tilted upwards.

[0051] Among them, the coordinating strip 39 can be equipped with multiple screw holes 38 in the vertical height. By using the multi-position fixing of the screw holes 38 and adjusting the bolts, the initial height of the coordinating strip 39 can be changed, and the clamping force of the silicone body 310 on the power fitting can be adjusted.

[0052] The damper 24 is an adjustable model, and the internal oil resistance can be changed by a knob to adjust the buffer strength according to the weight of the metal.

[0053] The working principle of all the content in the above embodiments is as follows:

[0054] The following describes the working process of the first and second components:

[0055] Initial state: The limiting post 27 at the bottom of the substrate 26 is in the initial position above the through hole 22 of the annular disk 21, the auxiliary spring 25 is in a natural extension and contraction state, and the damper 24 is not under force.

[0056] When in use, the operator places the electrical fitting to be cut on the placement base plate 26. The weight of the fitting acts directly on the placement base plate 26, thereby causing the placement base plate 26 to move downward, providing a triggering force for subsequent positioning.

[0057] The gravity of the power fitting causes the placement base plate 26 to move downward, which in turn drives the synchronous rod 37 fixed on it to move vertically downward along the limiting tube 34. When the synchronous rod 37 moves downward, it pulls the bent body 35 to rotate around the positioning rod 33 through the connecting body 36. Since the bent body 35 is bent downward, its connection point with the positioning rod 33 is the fulcrum. The end of the bent body 35 near the connecting body 36 moves downward with the synchronous rod 37, and the end of the connecting coordination strip 39 moves downward, so that the multiple silicone bodies 310 connected on the coordination strip 39 gradually approach each other and press against the upper surface of the power fitting.

[0058] Furthermore, since the silicone body 310 is tilted upwards, under the influence of its state and shape, it comes into contact with the edge of the power fitting, thereby limiting its horizontal movement in multiple ways: pressing the power fitting in the vertical direction to prevent jumping, and limiting the sliding displacement of the power fitting on the placement substrate 26 in the horizontal direction by the upward slightly tilted wave pattern.

[0059] After positioning the material to be cut, during cutting, the cutting disc 14 in the middle of the support frame 13 rotates and descends to cut the power fittings. The vibration generated during the cutting process is absorbed by the damper 24 at the bottom of the placement substrate 26, which reduces stress damage to the fittings and devices. Furthermore, with the cooperation of the auxiliary spring 25, the elasticity of the placement substrate 26 allows for a small adaptive displacement in the vertical direction, which counteracts high-frequency vibration and avoids cutting trajectory deviation caused by vibration. The limiting posts 27 on both sides, in conjunction with the through holes 22, further limit the offset of the placement substrate 26. To ensure cutting accuracy, the cutting disc 14 is adjusted only in the vertical direction. With different diameters of the limiting plate 28 and the limiting post 27, the displacement of the placement substrate 26 is limited to avoid positioning failure. After cutting, the cutting disc 14 rises and resets. The operator removes the cut power fittings, the gravity on the placement substrate 26 disappears, and the elastic force of the auxiliary spring 25 pushes the placement substrate 26 to reset upward. Simultaneously, the synchronizing rod 37 moves upward, and the connecting body 36 pulls the bending body 35 to rotate in the opposite direction, so that the coordinating strip 39 and the silicone body 310 move away from the placement substrate 26. The device returns to its initial state and waits for the next cutting operation.

[0060] Firstly, through the linkage structure of the second component, the positioning action is triggered by the gravity of the power fitting itself. The coordinated action of the bending body 35, the connecting body 36 and the synchronous rod 37 makes the wave-shaped silicone body 310 on the coordinating strip 39 precisely press against the upper surface of the fitting. The upward slight tilt design of the silicone body 310 combined with the wave pattern not only suppresses the jumping of the fitting in the vertical direction, but also restricts its sliding displacement in the horizontal direction. With the sliding limit of the limiting post 27 and the through hole 22, it is ensured that the placement base plate 26 is only slightly adjusted in the vertical direction. This ensures the stable posture of the fitting during the cutting process from multiple dimensions and greatly improves the cutting accuracy.

[0061] Secondly, the adjustable model 24 in the first component can flexibly adjust the buffer strength according to the weight of the hardware, and accurately absorb the impact force applied by the cutting disc 14; the auxiliary spring 25 allows the placement substrate 26 to generate a small adaptive displacement through elastic deformation, which cancels high-frequency vibration and avoids the cutting trajectory deviation caused by vibration; the two work together to significantly reduce stress damage to the hardware, while reducing the wear of the device components and extending the service life of the equipment.

[0062] Third, the positioning process does not require an additional power source and is automatically triggered by the gravity of the fitting. After cutting, the auxiliary spring 25 is used to achieve automatic reset, reducing manual intervention steps and improving work efficiency. The coordinating strip 39 adjusts the initial height through the multi-position screw hole 38 and can flexibly adjust the clamping force of the silicone body 310 according to the hardness of the fitting, adapting to the positioning needs of fittings of different materials. It is easy to operate and highly adaptable.

[0063] Fourth, the components of the device adopt a symmetrical layout to ensure balanced force and avoid excessive wear on one side; the hard silicone material and wave structure of the silicone body 310 take into account both wear resistance and positioning effect, and the detachable design facilitates later maintenance and replacement; the combination of adjustable models and multi-level coordination strips 39 enables it to adapt to power fittings of different weights and shapes, greatly expanding the applicability of the device and meeting the needs of diverse cutting scenarios.
