Description

Technical Field

[0001] This utility model relates to the field of sprocket manufacturing technology, specifically to an inspection device for sprocket manufacturing. Background Technology

[0002] A sprocket is a wheel with interlocking chain teeth, mainly used to mesh with precisely pitched blocks on link chains or cables. As a key component of mechanical transmission, sprockets are widely used in various mechanical transmission systems, especially in chemical, textile machinery, and food processing fields. During the production and processing of sprockets, it is necessary to sample and inspect sprockets in the same batch. The purpose of this is to ensure that the quality and performance of the sprockets meet the design requirements and industry standards, so that the sprockets can be stably connected or anchored with other components in subsequent actual use.

[0003] When using existing sprocket production inspection equipment, the inspection of the thread hole distance on the outer side of the sprocket is generally done with a measuring tape. However, measuring tape inspection not only requires the staff to hold the tape for a long time, but also requires ensuring that the measuring tape does not slip or deviate from the path during the measurement process. This is a considerable labor burden for the staff, and the operation is complex and prone to errors. It cannot achieve quick inspection of the thread hole distance on the outer side of the sprocket, which is not conducive to the sprocket inspection work. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-6 As shown, an inspection device for sprocket production includes an annular seat 1, with a limit stop 2 fixedly connected to one end of the annular seat 1. The annular seat 1 is equipped with a measuring component 3 for quick inspection of the thread hole distance on the outer side of the sprocket. By setting the measuring component 3, quick inspection of the thread hole distance on the outer side of the sprocket can be achieved, reducing the difficulty of thread hole distance inspection and making it easier for workers to operate. A U-shaped frame 8 is installed on the inner wall of the annular seat 1. The top of the inner cavity of the U-shaped frame 8 is provided with a boss 9. The boss 9 is equipped with a positioning component 10 that makes the annular seat 1 more stable. By setting the positioning component 10, the annular seat 1 can be initially positioned as a whole, which is beneficial to improving the accuracy of subsequent thread hole distance inspection data.

[0025] The positioning component 10 includes two receiving cavities 101 disposed inside the boss 9. A second movable block 102 is slidably connected inside each receiving cavity 101. A first through groove 103 is formed at the bottom of each receiving cavity 101. The bottom of each second movable block 102 extends through to the outside of the first through groove 103 and is fixedly connected to an L-shaped plate 104. Springs 105 are provided on the sides of the two second movable blocks 102 that are close to each other. The springs 105 are respectively connected to the second movable block 102 and the receiving cavity 101. Figure 1 , Figure 6As shown, before inspecting the thread hole spacing on the outer side of the sprocket, the spring 105 can be used to drive the second moving block 102 to slide along the length direction of the first through groove 103 at the bottom of the receiving cavity 101 until the L-shaped plate 104 at the bottom of the second moving block 102 contacts the inner wall of the sprocket to be inspected. This achieves the initial positioning of the ring seat 1 as a whole, which is beneficial to improving the accuracy of the subsequent thread hole spacing inspection data.

[0026] A second through groove 11 is provided at the top of the receiving cavity 101, and a push-pull plate 12 is provided inside the second through groove 11. The bottom of the push-pull plate 12 is connected to the second moving block 102, such as... Figure 6 As shown, when the inspection is completed and the ring seat 1 needs to be removed as a whole, the staff can use the push-pull plate 12 to overcome the elastic potential energy of the spring 105 and drive the L-shaped plate 104 to slide away from the inner wall of the sprocket. At this time, the L-shaped plate 104 separates from the inner wall of the sprocket, and the ring seat 1 can be easily removed as a whole.

[0027] The measuring component 3 includes a first movable block 31 disposed inside the annular seat 1. An adjusting plate 32 is fixedly connected to one side of the first movable block 31. A first mating bolt 33 is spirally connected inside the first movable block 31. A second mating bolt 34 is spirally connected inside the limiting block 2. A guide groove 35 is provided on the inner wall of the annular seat 1. Figure 1 , Figure 2 and Figure 4 As shown, when inspecting the thread hole spacing on the outer side of the sprocket, the second mating bolt 34 must first be connected to the first thread hole to be tested. Then, the first moving block 31 is slid to the second thread hole to be tested, so that the first mating bolt 33 is connected to the second thread hole to be tested. At this time, the distance between the first mating bolt 33 and the second mating bolt 34 corresponds to the thread hole spacing of the sprocket. This achieves quick inspection of the thread hole spacing on the outer side of the sprocket. Compared with the common tape measure inspection method, it does not require the staff to hold it for a long time, which simplifies the thread hole spacing inspection process, reduces the difficulty of thread hole spacing inspection, and is more convenient to adjust, making it easier for staff to get started.

[0028] A pointer 4 is fixedly connected to the top of the adjusting plate 32, and a measuring scale 5 is provided at the top edge of the annular seat 1, such as... Figure 2 , Figure 3 As shown, after the first mating bolt 33 and the second mating bolt 34 are respectively inserted into the two corresponding threaded holes to be tested, the measurement scale value 5 indicated by the pointer 4 on the top of the adjusting plate 32 is the distance between the two threaded holes to be tested. It should be noted that the measurement scale value 5 corresponds to the circumference scale value of the same batch and model of sprocket. In actual use, the measurement scale value 5 on the top of the ring seat 1 can be changed accordingly according to the specific model and size of the sprocket produced by the sprocket production line.

[0029] The top and bottom of the first movable block 31 are both fixedly connected to sliders 6. A groove 7 corresponding to the slider 6 is provided on the inner wall of the annular seat 1, and the slider 6 is located inside the groove 7. Figure 3 As shown, by setting the slider 6 and the groove 7, on the one hand, the first moving block 31 can be kept smooth during the sliding process, and on the other hand, the first moving block 31 can be prevented from detaching from the inside of the annular seat 1, which is conducive to improving the working stability of the measuring component 3.

[0030] One side of the ring-shaped base 1 is provided with a gripping handle 13 to improve the overall portability of the inspection tool, such as... Figure 1 , Figure 2 As shown, by setting the grip handle 13, the overall portability and operability of the ring seat 1 are improved.

[0031] Working principle: First, the operator uses the grip handle 13 to place the annular seat 1 on the outside of the threaded hole of the sprocket to be inspected. Then, the positioning component 10 allows the bottom L-shaped plate 104 of the second moving block 102 to contact the inner wall of the sprocket to be inspected, thus achieving the initial positioning of the annular seat 1 as a whole. This helps to improve the accuracy of the subsequent thread hole distance inspection data. When inspecting the thread hole distance on the outside of the sprocket, the measuring component 3 can be connected to the two threaded holes to be tested respectively. The distance between the two threaded holes to be tested corresponds to the thread hole distance of the sprocket. This enables quick inspection of the thread hole distance on the outside of the sprocket, simplifies the thread hole distance inspection process, reduces the difficulty of thread hole distance inspection, and is relatively convenient to adjust, making it easier for operators to get started.
