Description

Technical Field

[0001] This utility model relates to the field of glass insulator testing technology, and more specifically, to a glass insulator bottom thickness gauge. Background Technology

[0002] Glass insulators are important electrical equipment, widely used in power transmission and distribution systems. Their main function is to support and insulate power conductors, ensuring that current does not leak to the ground or other conductors. The bottom of the glass insulator has a metal cap, and the inner bottom of the cap has a metal ball head. Both the cap and the ball head are connected to the glass insulator with cement adhesive.

[0003] Glass insulators serve to isolate and insulate the cap and ball head. Therefore, there are strict requirements for the thickness of the bottom of the glass insulator during the production process. In the current production process, measuring glass insulators requires the use of calipers by the testing personnel. The calipers need to be adjusted every time they are measured, and the scale on the calipers is small, making it inconvenient to quickly read the measurement results. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a glass insulator bottom thickness gauge, which has the advantage of rapid detection and reading of the bottom thickness of glass insulators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass insulator bottom thickness gauge, comprising a worktable, with support legs fixedly connected to the four corners of the bottom of the worktable, a placement frame installed in the middle of the top of the worktable, a fixed frame fixedly connected to the back of the top of the worktable, a top plate fixedly connected to the top of the fixed frame, a lifting assembly installed in the middle of the top of the top of the top plate, a drive assembly installed on the right side of the top of the top of the top plate, a buffer assembly installed at the bottom of the lifting assembly, a measuring ruler installed in the middle of the bottom of the buffer assembly, an indicating assembly installed on the front of the fixed frame, the lifting assembly including a rotating block movably connected to the top of the top plate, a lead screw threaded into the inner side of the rotating block, a lifting plate fixedly connected to the bottom of the lead screw, and an indicating assembly including a support plate fixedly connected to the front of the fixed frame, an indicating needle provided on the left side of the support plate, and a magnifying glass fixedly connected to the front of the left side of the support plate.

[0006] As a preferred embodiment of this utility model, a positioning rod is fixedly connected to the top of the lifting plate, and a positioning tube is movably sleeved on the top of the positioning rod. The top of the positioning tube is fixedly connected to the bottom of the top plate.

[0007] As a preferred embodiment of this utility model, the drive assembly includes a motor fixedly connected to the top of the top plate, a drive gear fixedly connected to the output shaft of the motor, and a driven gear fixedly sleeved on the outer side of the rotating block, wherein the driven gear meshes with the drive gear.

[0008] As a preferred embodiment of this utility model, the buffer assembly includes a cylindrical rod movably sleeved on the surface of the lifting plate, a mounting plate fixedly connected to the bottom of the cylindrical rod, a cylindrical block fixedly connected to the top of the cylindrical rod, and a buffer spring provided on the outer side of the cylindrical rod, the buffer spring being located between the lifting plate and the mounting plate.

[0009] As a preferred embodiment of this utility model, the measuring ruler is fixedly connected to the bottom of the mounting plate, and the front of the measuring ruler is provided with measuring scale.

[0010] As a preferred embodiment of this utility model, the bottom of the measuring ruler is threaded with a threaded post, the bottom of the threaded post is fixedly connected with a nut, a stop block is fixedly sleeved on the bottom of the outer side of the threaded post, and a pressure spring is provided on the outer side of the threaded post, the pressure spring being located between the stop block and the bottom of the measuring ruler.

[0011] As a preferred technical solution of this utility model, protective rubber is fixedly connected around the bottom of the block, and the protective rubber is made of polyurethane rubber material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model includes a lifting assembly, a driving assembly, a measuring scale, and an indicating assembly. The starting motor drives the drive gear to rotate, which in turn drives the rotating block to rotate through meshing with the driven gear. Under the thrust of the thread on the inner side of the rotating block, the lead screw moves vertically downwards along the inner side of the rotating block, thereby causing the lifting plate and the measuring scale to move vertically downwards. This allows the protective rubber to contact the bottom of the inner side of the glass insulator. The position where the indicating needle points to the measuring scale indicates the bottom thickness of the glass insulator. A magnifying glass can magnify the area pointed to by the indicating needle, allowing the measuring personnel to clearly read the measurement results and reducing the difficulty of manual operation.

[0014] 2. This utility model incorporates a buffer component and protective rubber. The buffer spring can play a buffering role during the measurement process. When the protective rubber comes into contact with and is squeezed by the glass insulator, the buffer spring is compressed, thereby converting the impact force into the elastic potential energy of the buffer spring. The protective rubber is made of polyurethane rubber material. Chloroprene rubber has good wear resistance and weather resistance, as well as high hardness, and can play a certain buffering role when in contact with the glass insulator.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a glass insulator bottom thickness gauge, including a worktable 1. Support legs 101 are fixedly connected to the four corners of the bottom of the worktable 1. A placement frame 102 is installed in the middle of the top of the worktable 1. A fixing frame 103 is fixedly connected to the back of the top of the worktable 1. A top plate 104 is fixedly connected to the top of the fixing frame 103. A lifting assembly 2 is installed in the middle of the top of the top of the top plate 104. A drive assembly 3 is installed on the right side of the top of the top of the top plate 104. A buffer assembly 4 is installed at the bottom of the lifting assembly 2. A measuring ruler 5 is installed in the middle of the bottom of the punching assembly 4. An indicator assembly 6 is installed on the front of the fixing frame 103. The lifting assembly 2 includes a rotating block 201 movably connected to the top of the top plate 104. A lead screw 202 is threaded into the inner side of the rotating block 201. A lifting plate 203 is fixedly connected to the bottom of the lead screw 202. The indicator assembly 6 includes a support plate 601 fixedly connected to the front of the fixing frame 103. An indicator needle 602 is provided on the left side of the support plate 601. A magnifying glass 603 is fixedly connected to the front of the left side of the support plate 601.

[0023] In this embodiment, the inner side of the placement frame 102 is adapted to the shape of the glass insulator. When the bottom of the protective rubber 504 contacts the bottom of the inner side of the placement frame 102, the indicator needle 602 points to the zero point of the measuring scale of the measuring ruler 5. When measuring the bottom thickness, the glass insulator is first placed inside the placement frame 102, and then the motor 301 is started to drive the drive gear 302 to rotate. Through the meshing action with the driven gear 206, the rotating block 201 is driven to rotate. Under the action of the threaded thrust inside the rotating block 201, the lead screw 202 moves vertically downward along the inner side of the rotating block 201, thereby driving the lifting plate 203 and the measuring ruler 5 to move vertically downward, so that the protective rubber 504 contacts the bottom of the inner side of the glass insulator. The position where the indicator needle 602 points to the measuring scale of the measuring ruler 5 is the bottom thickness of the glass insulator. The magnifying glass 603 can magnify the area pointed to by the indicator needle 602, so that the measuring personnel can clearly read the measurement results and reduce the difficulty of manual operation.

[0024] The top of the lifting plate 203 is fixedly connected to a positioning rod 204, and the top of the positioning rod 204 is movably sleeved with a positioning tube 205. The top of the positioning tube 205 is fixedly connected to the bottom of the top plate 104.

[0025] The positioning rod 204 and the positioning tube 205 work together to position the lifting plate 203, so that the lifting plate 203 can only move vertically and will not rotate.

[0026] The drive assembly 3 includes a motor 301 fixedly connected to the top of the top plate 104. The output shaft of the motor 301 is fixedly connected to a drive gear 302. A driven gear 206 is fixedly sleeved on the outer side of the rotating block 201. The driven gear 206 meshes with the drive gear 302.

[0027] The starter motor 301 drives the drive gear 302 to rotate, and through the meshing with the driven gear 206, it drives the rotating block 201 to rotate. The lead screw 202 is a non-rotatable structure, so when the rotating block 201 rotates, it can drive the lead screw 202 to move up and down.

[0028] The buffer assembly 4 includes a cylindrical rod 401 that is movably sleeved on the surface of the lifting plate 203. The bottom of the cylindrical rod 401 is fixedly connected to a mounting plate 402, and the top of the cylindrical rod 401 is fixedly connected to a cylindrical block 403. A buffer spring 404 is provided on the outside of the cylindrical rod 401. The buffer spring 404 is located between the lifting plate 203 and the mounting plate 402. A measuring ruler 5 is fixedly connected to the bottom of the mounting plate 402, and a measuring scale is provided on the front of the measuring ruler 5.

[0029] The buffer spring 404 can play a buffering role during the measurement process. When the protective rubber 504 comes into contact with the glass insulator and is squeezed, the buffer spring 404 is compressed, thereby converting the impact force into the elastic potential energy of the buffer spring 404.

[0030] The bottom of the measuring ruler 5 is threaded with a threaded post 501, the bottom of the threaded post 501 is fixedly connected with a nut 502, the bottom of the outer side of the threaded post 501 is fixedly fitted with a stop block 503, and a pressure spring 505 is provided on the outer side of the threaded post 501. The pressure spring 505 is located between the stop block 503 and the bottom of the measuring ruler 5.

[0031] After long-term use, the device will inevitably experience some wear and deformation, which will affect the accuracy of the measurement. When the protective rubber 504 contacts the bottom of the inner side of the placement frame 102 and the indicator needle 602 does not point to the zero point of the measurement scale, the nut 502 can be turned by wrench to drive the threaded column 501 to move up and down inside the measuring scale 5 for calibration. The pressure spring 505 has a large pushing force on the stop block 503, which makes the measuring scale 5 and the threaded column 501 have a large friction force, preventing the threaded column 501 from rotating during use.

[0032] Among them, protective rubber 504 is fixedly connected around the bottom of the stop 503. The protective rubber 504 is made of polyurethane rubber material.

[0033] Chloroprene rubber has good wear resistance and weather resistance, and has high hardness, which can play a certain buffering role when in contact with glass insulators.

[0034] Working principle and usage process of this utility model:

[0035] The inner side of the placement frame 102 is adapted to the shape of the glass insulator. When the bottom of the protective rubber 504 contacts the bottom of the inner side of the placement frame 102, the indicator needle 602 points to the zero point of the measuring scale of the measuring ruler 5. When measuring the bottom thickness, the glass insulator is first placed inside the placement frame 102. Then, the motor 301 is started to drive the drive gear 302 to rotate. Through the meshing action with the driven gear 206, the rotating block 201 is driven to rotate. Under the action of the thread thrust inside the rotating block 201, the lead screw 202 moves vertically downward along the inner side of the rotating block 201, thereby driving the lifting plate 203 and the measuring ruler 5 to move vertically downward. Then, the protective rubber 504 contacts the bottom of the inner side of the glass insulator. The position where the indicator needle 602 points to the measuring scale of the measuring ruler 5 is the bottom thickness of the glass insulator. The magnifying glass 603 can magnify the area pointed to by the indicator needle 602, so that the measuring personnel can clearly read the measurement results.
