Technical Field

[0001] This utility model relates to the field of forging quality inspection technology, specifically a device for measuring the coaxiality of cylindrical forgings. Background Technology

[0002] The cylinder is an important component of many mechanical parts and structural components, and is widely used in aerospace, automobile manufacturing, petrochemical and other fields. The coaxiality of the cylinder is one of the key indicators for measuring its processing quality. The degree of coaxiality of the inner circle of the cylinder directly affects the assembly accuracy, operational stability and service life of the cylinder.

[0003] Currently, when measuring the coaxiality of a cylinder, dial indicators are mostly used to measure the coaxiality of the outer circle of the cylinder. However, the coaxiality of the inner circle of the cylinder is affected by the measurement space, and can only be detected at the edge of the inner circle of the cylinder, which cannot guarantee the measurement accuracy of the inner area of ​​the inner circle of the cylinder. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a coaxiality measuring device for cylindrical forgings, which can accurately measure the coaxiality of the inner circle of the cylinder, improve the measurement accuracy, and effectively solve the problems in the background art.

[0014] As a preferred embodiment of this utility model, the translation mechanism includes a slide rail, a slide block, a fixed plate, a hydraulic telescopic rod, a support plate, and a connecting rod;

[0024] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 3 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a coaxiality measuring device for cylindrical forgings, including a base 1, a rotating support assembly 2, a measuring mechanism 4, a positioning mechanism 5, and a translation mechanism 6;

[0026] The rotating support assembly 2 is existing technology. It is located at the upper end of the base 1 and mainly controls the rotation of the rollers through a motor, thereby causing the cylinder 3 placed on the rotating support assembly 2 to rotate along its own axis.

[0027] The measuring mechanism 4 is set on one side of the rotating support assembly 2. The measuring mechanism 4 includes a measuring head 41 and a mounting plate 42. The measuring head 41 is fixed on the mounting plate 42 and contacts the inner side of the cylinder 3. It is used to convert the measurement data into an electrical signal and transmit it to the external data processing system. The external data processing system calculates the coaxiality deviation of the inner circle of the cylinder 3 through the data processing module and generates an inspection report to accurately measure the coaxiality of the inner circle of the cylinder 3 at various positions.

[0028] The positioning mechanism 5 includes a vertical plate 51, a strip-shaped through hole 52, a slide rod 53, a slider 54, a stud 55, and a locking nut 56. One side of the vertical plate 51 is connected to the translation mechanism 6. The height of the vertical plate 51 is much smaller than the inner diameter of the cylinder 3 and does not contact the inner side of the cylinder 3. The vertical plate 51 is provided with a strip-shaped through hole 52. A slide rod 53 is provided in the strip-shaped through hole 52. A slider 54 is slidably connected to the outer side of the slide rod 53. One side of the slider 54 is fixedly connected to the mounting plate 42. A stud 55 is connected to the other side of the slider 54. The stud 55 passes through the strip-shaped through hole 52 and a locking nut 56 is threadedly connected to the outer side of the stud 55. The outer dimensions of the locking nut 56 are larger than the width of the strip-shaped through hole 52. By moving the slider 54, the measuring head 41 is controlled to contact the inner side of the cylinder 3. It is suitable for measuring the coaxiality of cylinders 3 with different inner diameters.

[0029] The translation mechanism 6 includes a slide rail 61, a slide block 62, a fixed plate 63, a hydraulic telescopic rod 64, a support plate 65, and a connecting rod 66. The slide rail 61 is fixed to the upper surface of the base 1, the slide block 62 is slidably connected to the upper end of the slide rail 61, the fixed plate 63 is fixed to the slide block 62, one end of the connecting rod 66 is connected to the fixed plate 63, and the other end of the connecting rod 66 is connected to the vertical plate 51. The support plate 65 is fixed to the upper surface of the base 1 and is located on one side of the slide rail 61. The support plate 65 and the fixed plate 63 are connected by the hydraulic telescopic rod 64. The extension of the hydraulic telescopic rod 64 controls the movement of the measuring mechanism 4 in the inner hole of the cylinder 3, so that the measuring head 41 performs coaxiality measurement on various positions of the inner circle of the cylinder 3.

[0030] To ensure that the rotation axis of the cylinder 3 does not deviate after it is placed on the rotating support assembly 2, an alignment mechanism 7 is also provided. The alignment mechanism 7 includes a vertical plate 71, a laser receiver 72, and a laser emitter 73. The vertical plate 71 is located on the other side of the rotating support assembly 2. The laser receiver 72 is mounted on the vertical plate 71, and the laser emitter 73 is mounted on the support plate 65. The laser emitter 73 and the laser receiver 72 are located on the same plane, and the horizontal laser emitted by the laser emitter 73 coincides with the central axis of the cylinder 3.

[0031] To minimize the impact of external vibrations on the measurement results during the measurement process, multiple shock-absorbing seats 8 are evenly distributed on the lower surface of the base 1.

[0032] In use: First, place the cylinder to be measured on the rotating support assembly 2. Start the hydraulic telescopic rod 64 to push the measuring mechanism 4 to the end face of the inner circle of the cylinder 3. Move the slider 54 to make the measuring head 41 contact the inner side of the cylinder 3. Then tighten the locking nut 56 to fix the position of the measuring head 41. At this time, the rotating support assembly 2 starts and controls the cylinder 3 to rotate along its own axis. The measuring head 41 detects the coaxiality of the inner circle of the cylinder 3 and transmits the signal to the external data processing system. The external data processing system calculates the coaxiality deviation of the inner circle of the cylinder 3 at this position and generates a test report. Continue to control the hydraulic telescopic rod 64 to extend and measure the coaxiality of other positions of the inner circle of the cylinder 3.

[0033] This invention can measure the coaxiality of the inner circle of a cylindrical forging. The positioning mechanism 5 is applicable to the coaxiality detection of cylindrical bodies 3 with different inner diameters, improving the versatility of the measurement. The translation mechanism 6 can accurately measure the coaxiality at different positions of the inner circle of the cylindrical body 3, improving the measurement accuracy and ensuring the machining quality of the inner circle of the cylindrical forging.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
