[0002] The multi-functional height gauge for crankshaft machining is a precision measuring device used in the process of crankshaft machining. It is mainly used to accurately measure parameters such as the height dimensions, shape deviations, and relevant position accuracies of various parts of the crankshaft, and can accurately measure the height of parts such as crankshaft journals and crank arms relative to a certain reference plane.

[0003] The multi-functional height gauge for crankshaft machining uses non-contact measurement. The laser beam irradiates the surface of the crankshaft, and the position change of the reflected light is received by the optical sensor. The height information of the crankshaft surface is calculated according to the principle of triangulation.

[0004] During the process of crankshaft machining, some cooling liquids or lubricants may be used. During machining, these liquids are heated and evaporated, which will increase the water vapor content in the workshop. Too high humidity may cause water vapor condensation on the surface of the optical elements of the multi-functional height gauge for crankshaft machining, thus interfering with the optical path of non-contact measurement. When the optical path is interfered, the optical measurement system cannot accurately obtain the angle and position information of the reflected light on the crankshaft surface, resulting in deviation of the measurement value and affecting the measurement accuracy.

[0029] As a further embodiment of the above technical solution: By setting the two ends of the rotating shaft 52 fixedly connected to the upper end of the height gauge 1, the sealing housing 51 is installed inside the sealing groove 4, the sealing sleeve 53 is in close contact with the inside of the sealing groove 4, the sealing sleeve 53 is set to be U-shaped, and the sealing housing 51 is rotatably connected to one side of the height gauge 1 through the rotating shaft 52. With the close fit of the sealing sleeve 53 and the sealing groove 4, it can effectively prevent external moisture, dust, etc. from entering the inside of the height gauge 1 and extend its service life;

[0030] As a further embodiment of the above technical solution: By setting the limiting rod 563 at the center position of the dehumidifying plate 55, the limiting rod 563 is set to be T-shaped, one end of the limiting rod 563 passes through the dehumidifying plate 55, the limiting rod 563 is perpendicular to one side of the dehumidifying plate 55, and the limiting rod 563 makes the movement of the push-pull plate 56 more stable and convenient for the operator to replace the dehumidifying block 58;

[0031] As a further implementation of the above technical solution: A plurality of dehumidifying plates 55 and push-pull plates 56 are provided. The dehumidifying plates 55 and the push-pull plates 56 are evenly and equidistantly arranged on both sides of the visual glass 54. The dehumidifying plates 55 are slidably connected to the push-pull plates 56 through the limiting rods 563. The dehumidifying plates 55 and the push-pull plates 56 correspond one by one.

Such a setting facilitates the installation and fixation of the dehumidifying blocks 58.

[0033] As a further implementation of the above technical solution: A plurality of mounting holes 57 are provided. The mounting holes 57 are evenly and equidistantly distributed on one side of the dehumidifying plate 55. The mounting holes 57 penetrate through the inside of the dehumidifying plate 55. The mounting holes 57 are parallel to each other, ensuring that the dehumidifying blocks 58 can be stably and accurately installed at the central positions of the mounting holes 57, and are not prone to shaking or displacement, guaranteeing the stability of the dehumidifying blocks 58 during the working process, and thus continuously and effectively carrying out the dehumidification work.

[0034] As a further implementation of the above technical solution: The vertical cross-sections of the molecular sieve blocks 583 and the silica gel 584 are both arranged in a flower shape. The outer sides of the molecular sieve blocks 583 and the silica gel 584 are closely attached to the inner side of the plastic shell 581. A plurality of adsorption holes 582 are provided. The adsorption holes 582 are evenly and equidistantly distributed on both sides of the plastic shell 581. The shape of the adsorption holes 582 is cylindrical. The adsorption holes 582 on both sides of the plastic shell 581 increase the contact area with the air, improving the dehumidification efficiency. The combination of the molecular sieve blocks 583 and the silica gel 584 can effectively adsorb moisture, maintaining a dry environment inside the sealing device 5, thereby guaranteeing the measurement accuracy and stability of the height gauge 1.

[0035] Workflow: When it is necessary to provide sealed protection for the altimeter 1, the operator rotates the sealed housing 51. The rotating shaft 52 at the upper end of the sealed housing 51 rotates at the upper end of the altimeter 1, driving the sealed housing 51 to rotate towards the sealing groove 4 on one side of the altimeter 1. As the sealed housing 51 rotates, the sealing sleeve 53 gradually enters the inner side of the sealing groove 4 and closely fits with the inner side of the sealing groove 4, effectively forming a sealing barrier to prevent external air, moisture, and dust from entering the interior of the altimeter 1. The visual glass 54 provided on the sealed housing 51 allows the operator to observe the internal situation of the altimeter 1 even in the sealed state. When it is necessary to perform measurement operations or adjust the altimeter 1, the operator rotates the sealed housing 51 in the reverse direction to disengage the sealing sleeve 53 from the sealing groove 4, and the rotating shaft 52 rotates again to drive the sealed housing 51 to open;

[0036] When the dehumidifying block 58 is saturated with adsorption or needs to be replaced, the operator pulls the push-pull plate 56. The provided limiting rod 563 slides at the central position of the dehumidifying plate 55 to restrict the moving direction of the push-pull plate 56, ensuring that the push-pull plate 56 can be smoothly pulled out. The old dehumidifying block 58 is taken out from the mounting hole 57, and then the dehumidifying block 58 is inserted into the mounting hole 57 on one side of the dehumidifying plate 55. The shape of the vertical cross-section of the mounting hole 57 is equal to the shape of the vertical cross-section of the dehumidifying block 58, ensuring that the dehumidifying block 58 can be stably installed at the central position of the mounting hole 57. Then the provided sealing plate 561 is installed back to its original position. When the sealing device 5 is in the closed state, the dehumidifying block 58 starts to work. The adsorption holes 582 on both sides of the plastic housing 581 allow air to contact the internal molecular sieve block 583 and silica gel 584. The provided adsorption holes 582 can increase the contact area between the dehumidifying block 58 and the air, improve the dehumidification effect, and effectively remove the moisture inside the sealing device 5. Then the crankshaft 3 is placed at a specific position at the bottom end of the altimeter 1. According to the measurement requirements, it is electrically connected through an external wire, and the control system of the altimeter 1 is started, driving the non-contact probe 2 to slide inside the altimeter 1 to approach the part to be measured of the crankshaft 3, preparing for measurement.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
