Description

Technical Field

[0001] This utility model relates to the field of insulator processing technology, and in particular to an automatic positioning and calibration fixture for ultra-high voltage glass insulator blanks. Background Technology

[0002] In existing technologies, the clamping of glass insulator blanks typically employs a single-clamping method. However, due to the considerable length of some glass insulator blanks, a single positioning often fails to achieve effective and stable fixation of the entire blank. This not only affects the stability during processing but may also lead to displacement or slippage of the blank during handling, thereby impacting the quality of the final product. Therefore, we propose an automatic positioning and calibration fixture for ultra-high voltage glass insulator blanks. Utility Model Content

[0003] The main purpose of this invention is to provide an automatic positioning and calibration fixture for ultra-high voltage glass insulator blanks, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic positioning and calibration fixture for ultra-high voltage glass insulator blanks includes a support frame. A lower clamping mechanism is fixedly installed on the lower part of the support frame, and an upper clamping mechanism is slidably installed on the upper part of the support frame. A sliding groove is opened in the upper part of the support frame, and an adjustment mechanism is slidably connected in the sliding groove. The adjustment mechanism is fixedly installed with the upper clamping mechanism. A control box is fixedly installed on the lower part of the support frame away from the lower clamping mechanism.

[0006] The upper clamping mechanism includes a connecting plate fixedly connected to the adjusting mechanism, a clamping assembly fixedly mounted on the connecting plate, and a driving assembly that is movably sleeved at the tail of the clamping assembly and drivenly connected to the head of the clamping assembly.

[0007] Preferably, the adjustment mechanism includes a first forward and reverse motor fixedly installed on the top of the support frame. The output end of the first forward and reverse motor is fixedly connected to a transmission screw, and the transmission screw is movably installed in a slide groove. A slider is threadedly connected to the transmission screw, and the slider is threadedly connected to the transmission screw.

[0008] By adopting the above technical solution, the adjustment mechanism can achieve precise adjustment of the height position of the upper clamping mechanism. The first positive and negative motor drives the transmission screw to rotate, which drives the slider connected to it to move up and down along the slide groove, thereby driving the upper clamping mechanism to perform lifting and lowering actions. This structure has high adjustment accuracy and fast response speed, and can be adapted to insulator blanks of different lengths and specifications, improving the versatility and automation level of the fixture.

[0009] Preferably, the clamping assembly includes a support rod fixedly connected to the connecting plate, a support plate fixedly connected to the end of the support rod away from the connecting plate, and two symmetrically distributed clamping bodies movably connected to the support plate, both of which are connected to the drive assembly for transmission.

[0010] By adopting the above technical solution, the clamping assembly can flexibly control the clamping body on the support plate. The two clamping bodies are symmetrically arranged, and the synchronous opening and closing action is achieved through the drive assembly, making the clamping process more stable and reliable. This design not only improves clamping efficiency but also allows for adaptive adjustments based on changes in the size of the insulator core rod, enhancing the applicability of the clamp.

[0011] Preferably, two mounting slots are symmetrically provided on the support plate; the clamping body includes a clamping rod, which is rotatably connected in the mounting slot, and a connecting rod is integrally formed on the end face of the clamping rod located in the mounting slot; a clamping plate is fixedly connected to the opposite ends of the two clamping rods, and a rubber pad is fixedly connected to the opposite ends of the two clamping plates.

[0012] By adopting the above technical solution: the clamping body achieves rotational movement through the structure of the clamping rod and the mounting groove, and works in conjunction with the connecting rod and the drive component to complete the closing and opening of the clamping plate. The rubber pad on the clamping plate effectively prevents surface damage to the glass insulator blank during the clamping process, protects the integrity of the workpiece, and improves clamping safety and yield.

[0013] Preferably, the drive assembly includes a threaded rod, which is movably sleeved on a support rod via a bearing. A connecting sleeve is threaded onto the threaded rod, and two traction rods are symmetrically connected to the connecting sleeve. The two traction rods are movably connected to the connecting rod on the same side, respectively. A transmission gear is fixedly connected to the threaded rod, and a drive gear is meshed with the outer side of the transmission gear. A second forward and reverse motor is fixedly connected to one end of the drive gear, and the second forward and reverse motor is embedded in the connecting plate.

[0014] By adopting the above technical solution: the drive assembly uses a No. 2 forward and reverse motor to drive the drive gear, which in turn drives the transmission gear and the threaded rod to rotate, so that the connecting sleeve moves axially and drives the clamping rod to rotate through the traction rod, thereby realizing the automatic opening and closing of the clamping plate. This structure has good self-locking performance, stable clamping force, and precise and controllable clamping action, and is suitable for continuous operation requirements in automated production environments.

[0015] Preferably, the structure of the lower clamping mechanism is the same as that of the upper clamping mechanism, the connecting plate on the upper clamping mechanism is fixedly connected to the slider, and the connecting plate on the lower clamping mechanism is fixedly connected to the support frame.

[0016] By adopting the above technical solution, the lower clamping mechanism and the upper clamping mechanism adopt the same modular structure design, which not only facilitates processing and manufacturing and subsequent maintenance, but also realizes the simultaneous clamping of both ends of the insulator blank core rod, improving clamping stability. The upper clamping mechanism is adjustable by a slider, while the lower clamping mechanism is fixed. The two work together to ensure firm clamping and accurate positioning, which is particularly suitable for clamping and fixing long glass insulator blanks.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the coordinated action of the lower clamping mechanism and the upper clamping mechanism, the core rod of the insulator blank can be clamped and fixed from both ends simultaneously, which significantly improves the stability and reliability of clamping. At the same time, by setting a sliding groove and adjusting mechanism in the support frame, the upper clamping mechanism can be adjusted up and down along the sliding groove direction, thereby achieving precise adaptation and clamping of glass insulator blank core rods of different lengths. It is especially suitable for the clamping needs of long blanks, effectively preventing them from shifting, tilting or even falling off during processing.

[0019] 2. The clamping mechanism adopts a dual-clamping rod linkage clamping structure controlled by the drive component. During the clamping process, the closing action of the clamping plate is realized through the transmission between the threaded rod and the connecting sleeve, and the self-locking characteristic of the thread is used to form a stable clamping force. This design not only ensures the smoothness and consistency of the clamping process, but also has good self-locking performance. Even under external vibration or load changes, it can maintain a stable clamping state without loosening, which greatly improves the safety of clamping and the accuracy of repeated use. At the same time, the surface of the clamping plate is equipped with a rubber pad, which can effectively buffer the pressure during the clamping process and prevent scratches or cracks from being caused to the glass insulator blank, protect the integrity of the workpiece, and further improve the yield and product quality.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An automatic positioning and calibration fixture for ultra-high voltage glass insulator blanks includes a support frame 1. A lower clamping mechanism 2 is fixedly installed on the lower part of the support frame 1, and an upper clamping mechanism 3 is slidably installed on the upper part of the support frame 1. A sliding groove 11 is opened in the upper part of the support frame 1, and an adjustment mechanism 4 is slidably connected in the sliding groove 11. The adjustment mechanism 4 is fixedly installed with the upper clamping mechanism 3. A control box 5 is fixedly installed on the lower part of the support frame 1 away from the lower clamping mechanism 2. The control box 5 contains control buttons, a control circuit board, and a battery. The second forward and reverse motor 335 and the first forward and reverse motor 41 on the lower clamping mechanism 2 and the upper clamping mechanism 3 are electrically connected to the control circuit board. Thus, the second forward and reverse motor 335 and the first forward and reverse motor 41 can be controlled through the control circuit board inside the control box 5. This is a conventional technical means in the prior art, so it will not be described in detail.

[0030] In this embodiment, the adjustment mechanism 4 includes a first forward and reverse motor 41 fixedly installed on the top of the support frame 1. The output end of the first forward and reverse motor 41 is fixedly connected to a transmission screw 42, and the transmission screw 42 is movably installed in the slide groove 11. A slider 43 is threadedly connected to the transmission screw 42, and the slider 43 is threadedly connected to the transmission screw 42. The structure of the lower clamping mechanism 2 is the same as that of the upper clamping mechanism 3. The connecting plate 31 on the upper clamping mechanism 3 is fixedly connected to the slider 43, and the connecting plate 31 on the lower clamping mechanism 2 is fixedly connected to the support frame 1.

[0031] Through the above scheme, the core rod of the insulator blank 6 can be clamped and fixed from both ends simultaneously by the structure of the lower clamping mechanism 2 and the synergistic effect of the upper clamping mechanism 3, which significantly improves the stability and reliability of clamping. At the same time, by setting the sliding groove 11 and the adjustment mechanism 4 in the support frame 1, the upper clamping mechanism 3 can be adjusted up and down along the sliding groove 11, thereby achieving precise adaptation and clamping of the core rod of the glass insulator blank 6 of different lengths. It is especially suitable for the clamping needs of long blanks, effectively preventing them from shifting, tilting or even falling off during processing.

[0032] In this embodiment, the upper clamping mechanism 3 includes a connecting plate 31 fixedly connected to the adjusting mechanism 4. A clamping assembly 32 is fixedly installed on the connecting plate 31. A driving assembly 33, which is movably sleeved at the tail of the clamping assembly 32 and driven by the head of the clamping assembly 32, is driven by the tail of the clamping assembly 32. The clamping assembly 32 includes a support rod 321 fixedly connected to the connecting plate 31. A support plate 322 is fixedly connected to the end of the support rod 321 away from the connecting plate 31. Two symmetrically distributed clamping bodies 323 are movably connected to the support plate 322, and both clamping bodies 323 are driven by the driving assembly 33. Two mounting slots 3221 are symmetrically opened on the support plate 322. The clamping body 323 includes a clamping rod 3232, which is rotatably connected in the mounting slot 3221 and located in the mounting slot 3221. The end face of 21 is integrally formed with a connecting rod 3231. The opposing ends of the two clamping rods 3232 are fixedly connected with clamping plates 3233. The opposing ends of the two clamping plates 3233 are fixedly connected with rubber pads 3234. The drive assembly 33 includes a threaded rod 331, which is movably sleeved on the support rod 321 through a bearing. A connecting sleeve 332 is threadedly connected to the threaded rod 331. Two traction rods 333 are symmetrically connected to the connecting sleeve 332. The two traction rods 333 are movably connected to the connecting rod 3231 on the same side. A transmission gear 334 is fixedly connected to the threaded rod 331. A drive gear 336 is meshed with the outer side of the transmission gear 334. A second forward and reverse motor 335 is fixedly connected to one end of the drive gear 336. The second forward and reverse motor 335 is embedded in the connecting plate 31.

[0033] Through the above scheme, both the lower clamping mechanism 2 and the upper clamping mechanism 3 adopt a linkage clamping structure with double clamping rods 3232 controlled by the drive component 33. During the clamping process, the closing action of the clamping plate 3233 is realized through the transmission between the threaded rod 331 and the connecting sleeve 332, and the self-locking characteristic of the thread is used to form a stable clamping force. This design not only ensures the smoothness and consistency of the clamping process, but also has good self-locking performance. Even under external vibration or load changes, it can maintain a stable clamping state without loosening, which greatly improves the safety of clamping and the accuracy of repeated use. At the same time, the surface of the clamping plate 3233 is provided with a rubber pad 3234, which can effectively buffer the pressure during the clamping process, prevent scratches or cracks from being caused to the glass insulator blank, protect the integrity of the workpiece, and further improve the yield and product quality.

[0034] It should be noted that this utility model is an automatic positioning and calibration fixture for ultra-high voltage glass insulator blanks. First, the glass insulator blank 6 to be clamped is placed between the two clamping plates 3233 of the lower clamping mechanism 2. Then, the adjusting mechanism 4 starts working, the first forward and reverse motor 41 starts and drives the transmission screw 42 to rotate, and the slider 43 slides smoothly up and down in the slide groove 11, driving the upper clamping mechanism 3 fixed to it to move down to the preset height, so that its clamping position is aligned with the top core rod of the insulator blank 6. When clamping and fixing the insulator blank 6, the control box 5 starts the second forward and reverse motor 335 in the lower clamping mechanism 2, drives the drive gear 336 connected to its output end to rotate, drives the transmission gear 334 meshing with it to rotate, and then makes the threaded rod 331 rotate synchronously. As the threaded rod 331 rotates, the connecting sleeve 332 moves along its... The axial movement, via the traction rods 333 connected to both sides, drives the two connecting rods 3231 to move, thereby driving the clamping rod 3232 to rotate around the shaft inside the mounting groove 3221, causing the two clamping plates 3233 to close inward, completing the clamping of the bottom core rod of the insulator blank 6. The second forward and reverse motor 335 inside the upper clamping mechanism 3 also starts, repeating the above clamping action, causing the upper clamping plate 3233 to clamp the top core rod of the insulator, achieving synchronous clamping at both ends. Throughout the clamping process, the rubber pads 3234 on the surface of the clamping plates 3233 act as buffers, preventing excessive clamping force from damaging the glass blank. Simultaneously, because the clamping action is achieved through threaded transmission, it has good self-locking performance. Even if the equipment is subjected to slight vibration or load changes during operation, the clamping state remains stable, ensuring the safety and reliability of the clamping. Furthermore, by adjusting the position of the slider 43, it can flexibly adapt to insulator blanks 6 of different lengths, improving the versatility and automation level of the clamp.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
