Description

Technical Field

[0001] This utility model relates to the field of testing and calibration equipment technology, specifically to an automatic testing and calibration device for metal shaft cores. Background Technology

[0002] Inspection and calibration equipment can be used to detect the position of workpieces, such as whether the axis of a rotating shaft is offset. Existing inspection devices often use lasers for inspection, which has a large error. After inspection, manual calibration is required, and inspection is performed again after manual calibration. This often requires multiple calibrations before the device can be used, resulting in low efficiency.

[0003] The existing patent publication number CN214583095U discloses an automated shaft detection and correction device. The device uses a shaft and a circular groove as coaxial lines. A plate that can be pressed against the outside of the shaft is set in the circular groove. A fixing sleeve is fixed to the end of the shaft. The shaft is coaxially installed in the circular groove on one side of the fixing sleeve. By rotating the adjusting screw, the plate is pressed against the surface of the second ball bearing on the outside of the shaft. In actual use, when the shaft rotates, excessive agitation will cause the plate and the second ball bearing to be squeezed too tightly and collide with each other, producing a sound. This achieves the purpose of detecting whether the shaft is deviated when it rotates and can correct the shaft in time.

[0004] The aforementioned patent requires the fixing sleeve to correspond with the rotating shaft and be installed outside the rotating shaft, which is cumbersome and has limitations. The sound generated by the collision between the plate and the second ball bearing due to excessive pressure is used to determine whether there is a deviation, which affects the service life and cannot effectively check the deviation of the rotating shaft, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic detection and correction device for metal shaft cores, so as to facilitate the observation of shaft offset and provide support to reduce deformation caused by the shaft's own weight.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic detection and calibration device for metal shaft cores, comprising a base, a rotating shaft, and a motor housing fixedly installed on the top right side of the base. A connecting mechanism is fixedly installed on the outside of the output shaft of the motor housing, and the rotating shaft is movably installed inside the connecting mechanism. A detection component is fixedly installed on the top left side of the base, and the connecting mechanism is engaged inside the detection component. A support component is fixedly installed on the top of the base. The detection component includes a vertical plate fixedly installed on the top of the base. A telescopic electric cylinder is fixedly installed on the outside of the vertical plate, and a docking sleeve is fixedly installed on the inside of the telescopic electric cylinder. A stop block is movably engaged inside the docking sleeve. Limit sleeves are fixedly connected to both the front and rear sides of the docking sleeve. A sliding column is movably engaged inside each limit sleeve. A scale mark is provided on the top of the sliding column, and an arrow corresponding to the scale mark is provided on the top of the limit sleeve. A ball bearing is movably engaged inside the sliding column.

[0007] Preferably, the top of the limiting sleeve is provided with a straight groove, the straight groove corresponds to the position of the scale mark, and the outer side of the sliding column is fixedly connected to a limiting plate.

[0008] Preferably, the outer side of the docking sleeve is fixedly connected with guide rods arranged symmetrically at the top and bottom, and the guide rods are movably engaged with the inside of the upright plate.

[0009] Preferably, a bearing sleeve is movably engaged in the middle of the mating sleeve, and the abutment block is movably installed inside the bearing sleeve.

[0010] Preferably, the docking sleeve and the connecting mechanism are arranged coaxially.

[0011] Preferably, the support assembly includes an elastic sleeve, a mounting bracket is fixedly mounted on the top of the elastic sleeve, a mounting groove is provided on the inner side of the mounting bracket, a shaft is movably mounted inside the mounting bracket, and a roller located in the mounting groove is movably mounted outside the shaft.

[0012] Preferably, the rollers are arranged symmetrically in front and behind the rotating shaft, located below the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The telescopic electric cylinder controls the inner movement of the docking sleeve outside the rotating shaft, pushing the limit plate to move the sliding column inward. The ball bearings are in close contact with the outer side of the rotating shaft. When the rotating shaft rotates, if the part inside the docking sleeve shifts, it will push the ball bearings outward. The sliding column slides inside the limit sleeve. The shift value of the rotating shaft is determined by the change in the position of the scale mark, making the detection of the rotating shaft shift more reliable and easier to operate. It can quickly and accurately find and correct the problem of the rotating shaft in the actual production process.

[0015] 2. The weight of the shaft is pressed onto the rollers and then transferred to the mounting bracket. The mounting bracket presses down on the elastic sleeve, and the rollers apply a supporting force to the shaft, reducing the deformation caused by the shaft's own weight, avoiding any impact on the testing and calibration results, and ensuring the stability of the shaft during the testing and calibration process.

[0022] 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: an automatic detection and correction device for metal shaft cores, including a base 1, a rotating shaft 4, and a motor housing 2 fixedly installed on the top right side of the base 1. A connecting mechanism 3 is fixedly installed on the outside of the output shaft of the motor housing 2, and the rotating shaft 4 is movably installed inside the connecting mechanism 3. A detection component 5 is fixedly installed on the top left side of the base 1, and the connecting mechanism 3 is engaged inside the detection component 5. A support component 6 is fixedly installed on the top of the base 1. The detection component 5 includes a vertical plate 51 fixedly installed on the top of the base 1, a telescopic electric cylinder 52 fixedly installed on the outside of the vertical plate 51, a docking sleeve 53 fixedly installed on the inside of the telescopic electric cylinder 52, and a stop block 54 movably engaged inside the docking sleeve 53. Both the front and rear sides are fixedly connected to limit sleeves 55. The inside of each limit sleeve 55 is movably engaged with a sliding column 56. The top of the sliding column 56 is provided with a scale mark 57. The top of the limit sleeve 55 is provided with an arrow corresponding to the scale mark 57. The inner side of the sliding column 56 is movably engaged with a ball bearing 58. The telescopic electric cylinder 52 controls the docking sleeve 53 to move inward and fit over the rotating shaft 4. By pushing the limit plate 59, the sliding column 56 moves inward, and the ball bearing 58 is close to the outside of the rotating shaft 4. When the rotating shaft 4 rotates, if the part of it inside the docking sleeve 53 is offset, it will push the ball bearing 58 to move outward. The sliding column 56 slides inside the limit sleeve 55. The offset value of the rotating shaft 4 can be determined by the change in the position of the scale mark 57, so as to adjust the rotating shaft 4 in time.

[0024] The top of the limiting sleeve 55 is provided with a straight groove, which corresponds to the position of the scale mark 57. The outer side of the sliding column 56 is fixedly connected to the limiting plate 59, which can prevent the sliding column 56 from coming out of the limiting sleeve 55. When the ball 58 pushes the sliding column 56 to move due to the offset of the rotating shaft 4, the sliding column 56 slides along the straight groove. The change in the position of the scale mark 57 and the arrow can be directly observed from the straight groove, which facilitates the accurate reading of the offset value of the rotating shaft 4. This makes the detection of the offset of the rotating shaft 4 more reliable and easier to operate. It can quickly and accurately find the problem of the rotating shaft 4 in the actual production process and take corresponding corrective measures in a timely manner, which effectively improves the quality and efficiency of metal shaft core production.

[0025] The outer side of the docking sleeve 53 is fixedly connected with guide rods 510 arranged symmetrically at the top and bottom. The guide rods 510 are movably engaged inside the upright plate 51. The guide rods 510 can play a good guiding role for the upright plate 51, ensuring that the docking sleeve 53 maintains a stable trajectory when moving up and down along the upright plate 51, reducing shaking and deviation. The upright plate 51 provides a solid support for the guide rods 510, making the operation more stable.

[0026] The bearing sleeve 511 is movably engaged in the middle of the mating sleeve 53, and the abutment block 54 is movably installed inside the bearing sleeve 511. The bearing sleeve 511 reduces the frictional resistance and wear of the abutment block 54 when it rotates.

[0027] The coupling sleeve 53 and the connecting mechanism 3 are set on the same axis, which enables more accurate operation of the rotating shaft 4 during the detection and calibration process, and improves the detection accuracy of the rotating shaft 4. The connecting mechanism 3 uses a three-rotor chuck or coupling to ensure a stable connection.

[0028] Please see Figure 2 and Figure 5 The support assembly 6 includes an elastic sleeve 61, a mounting bracket 62 fixedly mounted on the top of the elastic sleeve 61, a mounting groove 63 on the inner side of the mounting bracket 62, a shaft 64 movably mounted inside the mounting bracket 62, and a roller 65 movably mounted outside the shaft 64 in the mounting groove 63. The rollers 65, symmetrically positioned below the rotating shaft 4, contact the outer wall of the rotating shaft 4. The weight of the rotating shaft 4 presses on the rollers 65 and is transmitted to the mounting bracket 62. The elastic sleeve 61, which has a spring inside, contracts when the mounting bracket 62 is pressed down, thereby providing a certain support force to the rotating shaft 4 through the rollers 65. This reduces the deformation of the rotating shaft 4 caused by gravity, avoids affecting the detection and calibration results, and ensures the stability of the rotating shaft 4 throughout the detection and calibration process.

[0029] The rollers 65 are located symmetrically below the shaft 4, providing uniform and balanced support to the shaft 4. The symmetrical rollers 65 can stably bear the weight from the shaft 4.

[0030] Working principle: By fixing the rotating shaft 4 inside the connecting mechanism 3, the rotating shaft 4 is located above the support assembly 6, and the rollers 65 located symmetrically at the front and rear below the rotating shaft 4 contact the outer wall of the rotating shaft 4. The weight of the rotating shaft 4 presses on the rollers 65 and is transmitted to the mounting bracket 62. The mounting bracket 62 presses down to retract the spring sleeve 61 with an internal spring, thereby providing a certain support force to the rotating shaft 4 through the rollers 65.

[0031] By controlling the telescopic electric cylinder 52 to move the docking sleeve 53 inward, the docking sleeve 53 is fitted onto the outside of the rotating shaft 4, and the abutment block 54 provides support against the end of the rotating shaft 4. Then, by pushing the limiting plate 59 inward along the inside of the limiting sleeve 55, the sliding column 56 moves inward, so that the ball 58 abuts against the outer wall of the rotating shaft 4. The motor housing 2 drives the connecting mechanism 3 to drive the rotating shaft 4 to rotate. When the part of the rotating shaft 4 located inside the docking sleeve 53 shifts during rotation, the ball 58 is pushed outward as the rotating shaft 4 rotates. The outward movement of the ball 58 causes the sliding column 56 to slide inside the limiting sleeve 55. By observing the positional changes of the arrow and scale mark 57 on the straight groove at the top of the limiting sleeve 55, the value of the offset of the rotating shaft 4 can be obtained, and the rotating shaft 4 can be corrected in time. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] 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.
