Description

Technical Field

[0001] The utility model belongs to the technical field of forgings, and in particular relates to a forging diameter measuring tool. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. After forging, the forging needs to be measured using measuring tools.

[0003] The existing measurement method is to hold the forging with a handheld vernier caliper and read the data to obtain the diameter of the forging. Since the length of the vernier caliper is fixed, the vernier caliper can only measure forgings that are shorter than its own length. When the diameter of the forging is greater than the length of the vernier caliper, it is necessary to replace a different measuring tool, which brings great inconvenience to the user. Secondly, the data is easily erroneous when read with the naked eye, which reduces the accuracy of the measurement data. Therefore, we provide a forging diameter measuring tool. Utility Model Content

[0004] The utility model aims to provide a forging diameter measuring tool to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a forging diameter measuring tool, comprising a top plate, an L-shaped frame is fixedly connected to the rear end of the left side of the top of the top plate, an electric slide is fixedly connected to the top of the L-shaped frame, a sliding column is slidably connected to the inner wall of the electric slide, a clamp is fixedly connected to one end of the sliding column, a laser rangefinder is fixedly connected to the top of the clamp, a measuring platform is fixedly connected to the inner wall at the center of the top plate, the top and bottom of the measuring platform are respectively located at the top and bottom of the top plate, and a baffle is fixedly connected to the right side of the top of the top plate and on one side of the measuring platform.

[0006] By adopting the above scheme, the forging is placed on the top of the measuring table, and then the sliding column is driven to move horizontally by the electric sliding table, and the clamping plate is driven to move horizontally by the sliding column, and the forging on the top of the measuring table is driven to move toward the baffle by the clamping plate until one side of the forging is tightly fitted with the inner side of the baffle, and the forging is limited by the cooperation of the baffle and the clamping plate, and then the laser rangefinder is started, and a beam of laser is emitted by the laser rangefinder. Because the position of the laser rangefinder is lower than the height of the baffle, when the laser contacts the surface of the baffle, it is reflected back to the photoelectric element inside the laser rangefinder, and the time from the emission to the reception of the laser beam is measured by the timer inside the laser rangefinder, and then the distance between the clamping plate and the baffle is calculated, and the diameter of the forging is obtained, thereby improving the accuracy of the measurement data, and then because the distance between the baffle and the clamping plate can be changed, forgings of different diameters can be measured, thereby improving the practicality of the device.

[0007] As a preferred embodiment of a forging diameter measuring tool, a first scale is provided on the surface of the clamping plate, and a second scale is provided on the front surface of the measuring platform.

[0009] As a preferred embodiment of a forging diameter measuring tool, through holes are provided on the top and bottom of the measuring platform, and the through holes are evenly distributed on the top and bottom of the measuring platform.

[0010] With the above solution, since the through holes are evenly distributed on the top and bottom of the measuring table, the airflow can be split to achieve the purpose of even blowing.

[0012] By adopting the above scheme, the motor is set to drive the rotating rod to rotate, and the rotating rod drives the fan blades to rotate. The rotation of the fan blades generates air flow. When the air flow rises, the hot forgings can be air-cooled, thereby reducing the temperature of the forgings.

[0013] As a preferred implementation of the forging diameter measuring tool, a power supply box is fixedly connected to the right side of the top of the base plate, and a battery is provided in the inner cavity of the power supply box.

[0014] By adopting the above scheme, the electrical equipment is powered by the battery to maintain the normal operation of the electrical equipment.

[0015] As a preferred implementation of a forging diameter measuring tool, a guide groove is provided on the top of the L-shaped frame, and the diameter of the guide groove is greater than the diameter of the sliding column.

[0016] By adopting the above solution, the guide groove is provided to assist the sliding column in lateral movement, thereby improving the stability of the sliding column during movement.

Because the position of the laser rangefinder is lower than the height of the baffle, when the laser contacts the surface of the baffle, it is reflected back to the photoelectric element inside the laser rangefinder, and the time from the emission to the reception of the laser beam is measured by the timer inside the laser rangefinder, and then the distance between the clamping plate and the baffle is calculated, and the diameter of the forging is obtained, thereby improving the accuracy of the measurement data, and then because the distance between the baffle and the clamping plate can be changed, forgings of different diameters can be measured, thereby improving the practicality of the device.

[0019] 2. The utility model drives the rotating rod to rotate through the setting of the motor, and drives the fan blades to rotate through the rotating rod.

[0024] See also Figure 1-3 , a forging diameter measuring tool, comprising a top plate 1, see Figure 2As shown, the bottom of the top plate 1 is fixedly connected with support columns all around, and the bottom of the support columns is fixedly connected with the bottom plate 9, and a motor 10 is fixedly installed at the center of the top of the bottom plate 9, and the output end of the motor 10 is fixedly connected with a rotating rod 11, and the surface of the rotating rod 11 is fixedly connected with a fan blade 12. Through the setting of the motor 10, the rotating rod 11 is driven to rotate, and the rotating rod 11 drives the fan blade 12 to rotate, and the rotation of the fan blade 12 generates air flow. When the air flow rises, the hot forging can be air-cooled, thereby reducing the temperature of the forging, the rear end of the left side of the top of the top plate 1 is fixedly connected with an L-shaped frame 4, and the top of the L-shaped frame 4 is fixedly connected with an electric slide 5, and the inner wall of the electric slide 5 is slidably connected with a slide column 6, and one end of the slide column 6 is fixedly connected with a clamping plate 7, see Figure 1 As shown, the surface of the clamping plate 7 is provided with a first scale, and the front surface of the measuring platform 2 is provided with a second scale. By setting the first scale, when measuring the diameter of the forging, the thickness of the forging can also be measured, so that the obtained data is more comprehensive. The top of the clamping plate 7 is fixedly connected with a laser rangefinder 8, and the inner wall at the center of the top plate 1 is fixedly connected with the measuring platform 2. The top and bottom of the measuring platform 2 are respectively located at the top and bottom of the top plate 1. A baffle 3 is fixedly connected to the right side of the top of the top plate 1 and on one side of the measuring platform 2. The forging is placed on the top of the measuring platform 2, and then the sliding column 6 is driven to move horizontally by the electric slide 5, and the clamping plate 7 is driven to move horizontally by the sliding column 6, and the forging on the top of the measuring platform 2 is driven to move toward the baffle 3 by the clamping plate 7. The laser rangefinder 8 is moved in the same direction until one side of the forging is tightly fitted with the inner side of the baffle 3, and the forging is limited by the cooperation of the baffle 3 and the clamping plate 7. Then, the laser rangefinder 8 is started, and a laser beam is emitted through the laser rangefinder 8. Because the position of the laser rangefinder 8 is lower than the height of the baffle 3, when the laser contacts the surface of the baffle 3, it is reflected back to the photoelectric element inside the laser rangefinder 8. The time from the emission to the reception of the laser beam is measured by the timer inside the laser rangefinder 8, and then the distance between the clamping plate 7 and the baffle 3 is calculated, and the diameter of the forging is obtained, thereby improving the accuracy of the measurement data. Then, because the distance between the baffle 3 and the clamping plate 7 can be changed, forgings of different diameters can be measured, thereby improving the practicability of the device.

[0025] See Figure 1 As shown, the top and bottom of the measuring platform 2 are provided with through holes, and the through holes are evenly distributed on the top and bottom of the measuring platform 2. Since the through holes are evenly distributed on the top and bottom of the measuring platform 2, the airflow can be diverted to achieve the purpose of uniform blowing. Figure 2 As shown, a power supply box is fixedly connected to the right side of the top of the bottom plate 9, and a battery is arranged in the inner cavity of the power supply box. The battery is arranged to supply power to the electrical equipment to maintain the normal operation of the electrical equipment. Figure 3As shown, a guide groove 13 is provided on the top of the L-shaped frame 4, and the diameter of the guide groove 13 is larger than the diameter of the sliding column 6. Through the setting of the guide groove 13, the sliding column 6 is assisted to move laterally, thereby improving the stability of the sliding column 6 when moving.

[0026] When in use, first place the forging on the top of the measuring table 2 with the cooperation of an external transport tool, then drive the rotating rod 11 to rotate through the motor 10, and drive the fan blades 12 to rotate through the rotating rod 11, and generate airflow through the rotation of the fan blades 12. When the airflow rises, the hot forged forging can be air-cooled, thereby reducing the temperature of the forging. During the air-cooling process, the electric slide 5 drives the slide column 6 to move laterally, and the slide column 6 drives the clamping plate 7 to move laterally, and the clamping plate 7 drives the forging on the top of the measuring table 2 to move toward the baffle 3 until one side of the forging is tightly fitted with the inner side of the baffle 3, and the baffle 3 and the clamping plate 7 are used to limit the forging, and then the laser ranging is started. Instrument 8, a laser beam is emitted through the laser rangefinder 8. Because the position of the laser rangefinder 8 is lower than the height of the baffle 3, when the laser beam contacts the surface of the baffle 3, it is reflected back to the photoelectric element inside the laser rangefinder 8. The time from the emission to the reception of the laser beam is measured by the timer inside the laser rangefinder 8, and then the distance between the clamping plate 7 and the baffle 3 is calculated, and the diameter of the forging is obtained. At the same time, by setting the first scale on the surface of the clamping plate 7, the thickness of the forging can be read, so that the obtained data is more comprehensive and the accuracy of the measurement data is improved. Then, because the distance between the baffle 3 and the clamping plate 7 can be changed, forgings of different diameters can be measured, thereby improving the practicability of the device.
