[0002] Saw teeth refer to the pointed teeth on a saw blade, or the shape or arrangement of teeth resembling those of animal teeth or machine teeth. Existing saw blades typically have teeth welded on or integrally cast. Before use, finished saw blades undergo qualification testing, including stress testing, thickness testing, strength testing, angle testing, flatness testing, and torque testing. Welded saw teeth are also subject to strength testing, typically by impacting them with a certain force to verify that they meet standard strength requirements.

The utility model inserts the saw blade to be tested into the outside of the second positioning column through the rotating shaft hole, and then first squeezes and fixes the saw blade body by a clamping mechanism, and then presses down the welded saw teeth in all directions by a pressing mechanism, thereby testing its welding strength, and is easy to use. After the saw teeth of the utility model are broken by the pressing mechanism, they will fall onto the workbench. Since the shape of the workbench is a quadrangular prism with a trapezoidal side, the broken saw teeth on the workbench will automatically slide down along the inclined slope of the top of the workbench. It is only necessary to place a collection box on one side of the workbench for collection, which is convenient for unloading and saves time and effort. The above utility model adds a collection structure for the crushed saw teeth, but the saw teeth themselves have a thin section and are sharp. When they are hit, some of them will splash, affecting the safety of the operator during the inspection and reducing the safe use of the equipment. Utility Model Content

[0025] This specific embodiment is a sawtooth welding strength testing device.

[0026] The above utility model adds a collection structure for the crushed saw teeth, but the saw teeth themselves have a thin section and are sharp. When they are hit, some of them will splash, affecting the safety of the operator during the inspection and reducing the safe use of the equipment.

[0027] Its structural diagram is as follows Figures 1-4 As shown. A sawtooth weld strength testing device includes a testing device body 1. Four sets of running wheels 11 are mounted on the bottom of the testing device body 1, and two sets of lateral slide grooves 21 are provided on the electric control frame 2. The running wheels 11 allow the testing device body 1 to be moved, ensuring the ease of use of the testing device body 1. The device also includes an electric control frame 2 fixedly mounted on the top of the testing device body 1, and an oil cylinder 3 fixedly mounted within the electric control frame 2. A telescopic rod 31 is mounted on the bottom of the oil cylinder 3, and a striking cone 32 is fixedly mounted on the bottom of the telescopic rod 31.

[0028] A protective cover 4 is fixedly mounted on the telescopic rod 31, and two sets of connecting blocks 41 are fixedly mounted on the ends of the protective cover 4. The connecting blocks 41 and the lateral slide 21 are slidably mounted via an auxiliary slider 42. The telescopic rod 31 is pushed by the oil cylinder 3, so that the striking cone 32 is extended and retracted to test the welding strength of the saw teeth. At the same time, the protective cover 4 cooperates with the auxiliary slider 42 to slide with the lateral slide 21, so that when the striking cone 32 strikes the saw teeth, the struck saw teeth are protected by the protective cover 4 to prevent the saw teeth from splashing and affecting the safety of the test. It also includes a placement table 6 fixedly mounted on the top of the detection device body 1. A saw blade 7 is placed on the top of the placement table 6, and a through hole 71 is opened at the center of the saw blade 7. The saw blade 7 is tested by placing it on the top of the placement table 6 and cooperating with the striking cone 32. A rotating bearing 53 is fixedly mounted on the bottom of the placement table 6. A fixed slot 61 is provided at the center of the top of the placement table 6. Two sets of fixed sliders 62 are slidably mounted on the fixed slot 61. A limit block 63 is fixedly mounted on the top of the fixed slider 62. Two sets of connecting springs 64 are installed between the limit blocks 63. One side of the connecting spring 64 is provided with a limit arc surface 65. A through hole 71 is provided in the saw blade 7. The saw blade 7 is placed on the top of the placement table 6. The limit block 63 passes through the through hole 71. The limit block 63 passes through the through hole 71 to clamp the saw blade 7, thereby ensuring the stability of the saw blade 7 during the inspection process and thus ensuring the accuracy of the inspection. The limit block 63 is also provided with a limit arc surface 65. The contact area with the through hole 71 is a curved surface, which effectively reduces the wear and tear of the saw blade 7 during the fixing process.

[0029] The apparatus also includes a drive motor 5 fixedly mounted within the testing device body 1 for rotating the placement table 6. A mounting slot 12 is defined within the testing device body 1, and the drive motor 5 is fixedly mounted within the mounting slot 12 via a mounting base 51. An output shaft 52 is provided at the top of the drive motor 5, extending through the testing device body 1 and fixedly connected to a rotating bearing 53. Upon activation of the drive motor 5, the output shaft 52 drives the rotating bearing 53 to rotate, thereby rotating the placement table 6. This causes the drive motor 5 to rotate the saw blade 7 as the oil cylinder 3 pushes the striking cone 32 to inspect the teeth on the saw blade 7, thereby achieving automated inspection for each set of teeth welded to the saw blade 7.

[0030] First, place the saw blade 7 on the top of the placement table 6, and pass the through hole 71 through the limit block 63. The saw blade 7 is clamped and fixed by the limit block 63 passing through the through hole 71, thereby ensuring the stability of the saw blade 7 during the detection process. By starting the drive motor 5, the output shaft 52 drives the rotating bearing 53 to rotate, so that the placement table 6 is rotated, and the telescopic rod 31 is pushed by the oil cylinder 3 to make the striking cone 32 extend and retract to achieve the test of the saw tooth welding strength. At the same time, the protective cover 4 cooperates with the auxiliary slider 42 and the lateral slide groove 21 to slide, so that when the striking cone 32 hits the saw teeth, the protective cover 4 protects the hit saw teeth to avoid the saw teeth splashing and affecting the safety of the detection.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
