Description

Technical Field

[0001] The utility model relates to the technical field of sprocket detection, in particular to a sprocket production inspection device. Background Art

[0002] A conveyor sprocket is a wheel with cog-type sprocket teeth, which is used to mesh with accurately pitched blocks on link links or cables. It is widely used in mechanical transmission in chemical industry, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.

[0003] Announcement No. CN 219996084 U discloses a sprocket production inspection device. After the existing sprocket production is completed, it is necessary to inspect the flatness of the sprocket to prevent the sprocket itself from bending, which may cause the chain to come off when it is assembled with the chain in the later stage. However, the current inspection device does not have a device to inspect the flatness of the sprocket, which often makes it troublesome to inspect the sprocket. The following solution is proposed, which includes an installation box, a rotating shaft is rotatably connected to the inner wall of the bottom of the installation box, and the top of the rotating shaft extends to the top of the installation box and is connected to a fixed component. However, the above technical solution has certain disadvantages. The flatness of only one side of the sprocket can be inspected at one time, and both sides of the sprocket cannot be inspected simultaneously. Moreover, when inspecting the sprocket, only uneven parts can be detected, and the detected difference cannot be recorded. The staff needs to continuously perform inspection and record, which is relatively cumbersome and troublesome, and the inspection is not convenient enough. Therefore, we propose a sprocket production inspection device to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 , an embodiment provided by the utility model: a sprocket production inspection device, comprising a base 1,

[0021] A rotating shaft 2 is rotatably installed on the base 1, a motor 8 is fixedly installed inside the base 1, a first gear 9 is rotatably installed inside the base 1, the first gear 9 is fixedly connected to the output shaft of the motor 8, a second gear 10 is rotatably installed inside the base 1, the second gear 10 is meshed with the first gear 9, the second gear 10 is fixedly connected to the rotating shaft 2, the rotating shaft 2 is provided with a locking assembly, a column 11 is fixedly installed on the left end of the base 1, and a detection assembly is provided on the base 1. This device fixes a sprocket on the locking assembly and installs the locking assembly with the sprocket fixed on the rotating shaft 2. The motor 8 drives the first gear 9, the second gear 10 and the rotating shaft 2 to rotate, thereby driving the sprocket to rotate, so that the sprocket can detect the flatness of the surface between the detection assemblies.

[0022] Furthermore, the locking assembly includes a sleeve 3, which is movably sleeved on the rotating shaft 2, and a support plate 4 is provided on the sleeve 3. The upper end of the sleeve 3 is sleeved with a first nut 5 through a thread, and the upper end of the rotating shaft 2 is sleeved with a second nut 6 through a thread. This structure sleeves the sprocket on the sleeve 3 and fixes the sprocket with the first nut 5. Then, the sleeve 3 is sleeved on the rotating shaft 2 and tightened with the second nut 6 to fix the sprocket on the sleeve 3, so that the sprocket can be fixed on the sleeve 3, which is convenient for the motor 8 to drive the sprocket to rotate for detection.

[0023] Furthermore, the detection component includes four groups of limit plates 12, which are fixedly mounted on the column 11, and two groups of slides 13 are slidably sleeved on the column 11. The two groups of slides 13 are located between the four groups of limit plates 12 in groups of two. Two groups of springs 14 are movably installed between the four groups of limit plates 12, and the right ends of the two groups of slides 13 are fixedly mounted with vertical rods 15. Ball bearings 16 are installed on the two groups of vertical rods 15, and fixing rings 17 are fixedly mounted on the upper and lower opposite ends of the two groups of vertical rods 15. Bolts 18 are inserted into the two groups of fixing rings 17 through threads. When the sprocket rotates, the two groups of vertical rods 15 fit with the upper and lower sides of the sprocket. When the two groups of vertical rods 15 detect unevenness on the sprocket, they drive the two groups of slides 13 to slide on the column 11, and drive the marking pens fixed in the two groups of fixing rings 17 to move up and down, so that the unevenness of the sprocket surface can be recorded by sliding the fixing rings 17 up and down, which is convenient for subsequent processing.

[0024] Furthermore, two groups of marking disks 7 are sleeved on the rotating shaft 2, and the two groups of marking disks 7 are respectively fitted with the upper and lower sides of the sleeve 3, and the two groups of fixing rings 17 are aligned parallel to the two groups of marking disks 7. This structure fixes the two groups of marking disks 7 on the rotating shaft 2, so that the marking pens fixed on the two groups of fixing rings 17 are fitted with the outer walls of the two groups of fixing rings 17. When the two groups of slides 13 and the two groups of vertical rods 15 drive the two groups of marking pens to slide up and down, they can draw marks on the outer walls of the two groups of marking disks 7, thereby accurately recording the unevenness of the sprocket surface.

[0025] Furthermore, annular scale values ​​are set on the outer walls of the two groups of marking disks 7, and the scale values ​​on the two groups of marking disks 7 are set with positive and negative numbers. This structure can accurately record the protruding and recessed parts of the sprocket surface according to the scale values ​​on the outer walls of the two groups of marking disks 7, which is convenient for subsequent polishing of the thicker parts of the sprocket.

[0026] Furthermore, the outer wall of the lower end of the rotating shaft 2 and the outer wall of the column 11 are both elliptical, and the left ends of the two groups of slides 13 and the inner wall of the sleeve 3 are respectively adapted to the inner walls of the column 11 and the two groups of marking disks 7 and the outer wall of the rotating shaft 2. This structure, based on the shape of the lower end of the rotating shaft 2 and the column 11, allows the two groups of slides 13 to slide up and down on the column 11 without rotating, and the sleeve 3 and the two groups of marking disks 7 fit tightly with the outer wall of the rotating shaft 2, so that when the rotating shaft 2 rotates, it can drive the sleeve 3 and the two groups of marking disks 7 to rotate.

[0027] Working principle: When the sprocket is fixedly installed, Figure 2 As shown, first sleeve the sprocket on the sleeve 3, and rotate and install the first nut 5 on the sleeve 3, fix the sprocket between the support plate 4 and the first nut 5, then sleeve a group of marking disks 7 on the rotating shaft 2, then sleeve 3 on the rotating shaft 2, and then sleeve another group of marking disks 7 on the rotating shaft 2, the two groups of marking disks 7 fit together with the upper and lower sides of the sleeve 3, and then rotate and install the second nut 6 on the rotating shaft 2, so that the sleeve 3 and the two groups of marking disks 7 can be fixed, and the two groups of vertical rods 15 fit together with the upper and lower sides of the sprocket, and then when the motor 8 drives the first gear 9, the second gear 10 and the rotating shaft 2 to rotate, the sleeve 3 on the rotating shaft 2, the two groups of marking disks 7 and the sprocket rotate synchronously, and the sprocket rotates between the two groups of vertical rods 15, as shown Figure 2 and Figure 4 As shown, the two groups of vertical rods 15 slide on the surface of the sprocket. When the unevenness of the sprocket surface is detected, the two groups of vertical rods 15 drive the two groups of slide plates 13 to slide on the column 11, and the two groups of slide plates 13 are slid and reset by two groups of springs 14. The two groups of marking pens are inserted into the two groups of fixing rings 17, and the marking pens inserted into the two groups of fixing rings 17 are tightly fixed by twisting the two groups of bolts 18. The tips of the two groups of marking pens fit into the outer walls of the two groups of marking disks 7. While the two groups of vertical rods 15 slide up and down, the tips of the marking pens fixed in the two groups of fixing rings 17 are driven to slide and draw on the outer walls of the two groups of marking disks 7, so that the specifications of the uneven parts of the sprocket surface can be marked on the two groups of marking disks 7. The above is the entire working principle of the utility model.
