Description

Technical Field

[0001] The utility model relates to the field of metering equipment for mechanical parts, in particular to an outer cover detection device for a steel wire rope electric hoist. Background Art

[0002] In the manufacturing process of electric hoists, the hoist cover is a key component connecting the motor and the reducer. After cutting, welding, turning and other processing procedures, quality inspectors can only use measuring tools to inspect the basic dimensions such as the length between the flanges on the mortise and tenon surfaces of the hoist cover and the diameter of the flange after processing, but the geometric tolerances such as parallelism and coaxiality cannot be effectively detected;

[0003] A Chinese utility model patent with announcement number CN202853555U discloses a device for detecting the coaxiality, verticality and parallelism of a sleeve-type workpiece. The existing method for detecting the coaxiality or parallelism of the two ends of a sleeve-type component is generally to install the sleeve-type component on a turntable structure for rotation, and then install a dial indicator next to the turntable structure, and perform detection by placing the detection head of the dial indicator against the outer wall or end face of the sleeve-type component; however, the existing detection equipment has two defects: first, the dial indicator is set on the outside, which is not convenient for detecting the coaxiality of the inner hole; second, when the sleeve-type component is large and heavy, the rotation is very constant and requires a larger load-bearing bearing, which is easy to affect the final measurement accuracy due to rotation support deviation. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a wire rope electric hoist outer cover detection equipment, which is more suitable for inner hole detection and improves the detection accuracy and convenience.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A wire rope electric hoist outer cover detection equipment is used to detect the parallelism and coaxiality of the groove flanges at both ends of the cover tube, comprising a first bearing, a rotating shaft, a base and a tenon flange mounted above the base, the convex tenon portion of the flange surface on the tenon flange is correspondingly inserted and adapted to the groove portion of the groove flange at the lower end of the detection cover tube, the outer wall of the outer ring of the first bearing is inserted and fixed in the central hole of the tenon flange, the lower end shaft body of the rotating shaft is inserted and fixed in the inner ring of the first bearing, the upper end shaft body of the rotating shaft is detachably installed with a dial indicator, and the detection head of the dial indicator can correspond to the upper flange surface or the central hole wall of the groove flange at the upper end of the detection cover tube.

[0007] Furthermore, the outer edge of the tenon flange is evenly provided with a plurality of connection holes that can be connected to the groove flange through a bolt assembly.

[0008] Furthermore, the base is provided with a mounting hole corresponding to the central hole of the tenon flange, a second bearing is installed in the mounting hole, and the lower end shaft body of the rotating shaft is inserted and fixed in the inner rings of the first bearing and the second bearing in sequence.

[0009] Furthermore, the base and the tenon flange are fixedly connected via a rib plate.

[0010] Furthermore, the dial indicator includes a magnetic base magnetically connected to the rotating shaft.

[0011] Furthermore, a rotating handle is installed on the upper end of the rotating shaft.

[0012] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0013] The utility model discloses a wire rope electric hoist outer cover detection equipment, which installs the cover cylinder on the tenon flange, and uses the tenon and groove cooperation of the tenon flange and the groove flange to perform center alignment and radial positioning, and then installs the dial indicator for detection on the rotating shaft, and utilizes the rotation of the rotating shaft in the cover cylinder to drive the dial indicator for detection, which can not only detect the parallelism of the flange surfaces of the upper and lower groove flanges by changing the dial indicator's marking position, but also makes it easier to detect the coaxiality of the center holes of the upper and lower groove flanges. At the same time, there is no need to rotate the large-volume cover cylinder, so the detection efficiency and detection accuracy are greatly improved, and the operation is also more convenient.

[0016] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0017] Combined with Figure 1The wire rope electric hoist outer cover detection equipment is used to detect the parallelism and coaxiality of the groove surface flanges 2 at both ends of the cover tube 3, and includes a first bearing 4, a rotating shaft 1, a base 7 and a tenon surface flange 5 mounted above the base 7. Specifically, the base 7 and the tenon surface flange 5 are fixedly connected by a rib plate 6, and a plurality of rib plates 6 are evenly arranged around the rib plate to ensure that the tenon surface flange 5 is supported and connected stably; the convex tenon portion of the flange surface on the tenon surface flange 5 is plug-fitted and adapted to the groove portion of the groove surface flange 2 at the lower end of the detection cover tube 3. The tenon surface flange is an existing flange structure, which is mainly used to facilitate the installation of the sealing ring and prevent the sealing ring from sliding. Here, its groove structure is used for plug-in and centering positioning, so that the rotating shaft 1 and the groove surface flange 2 at the lower end of the detection cover tube 3 are coaxial and correspondingly vertical, which is convenient for detecting the groove surface flange 2 at the upper end of the detection cover tube 3;

[0018] The outer wall of the outer ring of the first bearing 4 is inserted and fixed in the central hole of the tenon flange 5, and the lower end shaft body of the rotating shaft 1 is inserted and fixed in the inner ring of the first bearing 4, ensuring that the rotating shaft 1 is perpendicular to the tenon flange 5 and can rotate flexibly, and the verticality of the first bearing 4 and the tenon flange 5 is not lower than IT7 level. A rotating handle is installed on the upper end of the rotating shaft 1 for easy manual rotation. A dial indicator is detachably installed on the upper end shaft body of the rotating shaft 1. Specifically, the dial indicator includes a magnetic base magnetically connected to the rotating shaft 1, which is convenient for changing the installation position of the dial indicator along the axial direction of the rotating shaft 1, so that the detection head of the dial indicator can correspond to the upper flange surface or the central hole wall of the groove flange 2 at the upper end of the detection cover tube 3 to respectively detect the parallelism of the two groove flanges 2 and the coaxiality of the central hole.

[0019] It may not be stable to only rely on the insertion fit of the tenon part of the flange surface on the tenon flange 5 to perform axial and circumferential positioning of the groove flange 2. Therefore, according to needs, the outer edge of the tenon flange 5 is evenly provided with a plurality of connection holes that can be connected to the groove flange 2 by bolt assemblies. The connection holes need to avoid the rib plate 6 and are connected by inserting bolts to ensure that the connection positioning is stable.

[0020] As needed, the base 7 is provided with a mounting hole corresponding to the central hole of the tenon flange 5, and a second bearing 8 is installed in the mounting hole. The lower end shaft body of the rotating shaft 1 is inserted and fixed in the inner rings of the first bearing 4 and the second bearing 8 in sequence. By setting the first bearing 4 and the second bearing 8 to install and position the rotating shaft 1, better rotation support can be provided for the rotating shaft 1 and the dial indicator installed thereon, thereby preventing the rotating shaft 1 from having a large rotation deviation and affecting the measurement accuracy.

[0021] To implement the wire rope electric hoist housing inspection equipment of the utility model, it is only necessary to install the grooved flange 2 at the lower end of the electric hoist housing in place corresponding to the tenon flange 5, and then install and fix the dial indicator on the rotating shaft 1; if measuring parallelism, adjust the dial indicator, make the detection head of the dial indicator touch the upper flange surface of the grooved flange 2 at the upper end of the cover tube 3, and then rotate the rotating shaft 1 for inspection; if measuring verticality, adjust the dial indicator, make the detection head of the dial indicator touch the central hole wall of the grooved flange 2 at the upper end of the cover tube 3, and then rotate the rotating shaft 1 for inspection.
