Abstract
Description
Technical Field
[0001] This utility model relates to the field of synchronous belt production, specifically to a synchronous belt thickness calibration device. Background Technology
[0002] Synchronous toothed belts use steel wire rope or fiberglass rope as the reinforcing layer, covered with polyurethane or neoprene rubber on the outside. The inner circumference of the belt is toothed so that it meshes with toothed pulleys. Because the reinforcing layer deforms little under load, it can keep the circumferential pitch of the toothed belt constant. Therefore, there is no relative slippage between the belt and the pulley, thus ensuring synchronous transmission and a constant transmission ratio.
[0003] The thickness of a synchronous belt is a crucial parameter affecting its performance and service life. Synchronous belts require thickness calibration before leaving the factory. Existing testing techniques necessitate multiple clamping operations using a micrometer to determine the thickness. Therefore, those skilled in the art have provided a synchronous belt thickness calibration device to address the problems mentioned in the background section. Utility Model Content

[0005] A fixed frame is fixedly connected above the base between the limiting groove and the clamping frame. The upper end of the fixed frame is bent above the limiting groove. A distance sensor is installed below the upper end of the fixed frame. A display screen is installed above the upper end of the fixed frame. A support frame is fixedly connected to the upper end of the fixed frame on one side of the display screen.

[0010] Preferably, roller one and roller two are located on the same vertical plane.
[0011] Preferably, the width of the first roller is greater than the spacing between the limiting grooves.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model, by designing a clamping frame and a limiting groove, ensures that the synchronous belt can be positioned flat below the ranging sensor, thus ensuring the accuracy of ranging.
[0014] 2. This utility model is designed with a support frame and a clamping frame. The synchronous belt is supported by being sleeved on the outside of the support frame and the clamping frame. At the same time, rollers one and two are used to rotate the synchronous belt so that the synchronous belt moves under the distance sensor in sequence. This eliminates the need for multiple locking and locking operations, making the measurement more convenient. Attached Figure Description

[0029] Please see Figures 1-4 In this embodiment, a synchronous belt thickness calibration device is provided, including a base 1, a limiting groove 2 is provided above the base 1, and a clamping frame 3 is provided above the base 1 on one side of the limiting groove 2. The clamping frame 3 includes a fixed seat 31, the fixed seat 31 is fixed at both ends of the base 1, a rotating rod 32 is rotatably connected between the fixed seats 31, a spring 33 is connected between the rotating rod 32 and the fixed seat 31, a pressure rod 34 is fixedly connected to one side of the rotating rod 32, the pressure rod 34 is located at both ends of the limiting groove 2, and a roller 35 is rotatably connected above the pressure rod 34.
[0030] A fixed frame 4 is fixedly connected above the base 1 between the limiting groove 2 and the clamping frame 3. The upper end of the fixed frame 4 is bent above the limiting groove 2. A distance sensor 7 is installed below the upper end of the fixed frame 4. A display screen 6 is installed above the upper end of the fixed frame 4. A support frame 5 is fixedly connected to the upper end of the fixed frame 4 on one side of the display screen 6.
[0031] The support frame 5 includes a top plate 51, which is fixed above the fixed frame 4. Sliding plates 52 are slidably connected to both ends of the top plate 51. A connecting rod 55 is fixedly connected to one end of the sliding plate 52, and rollers 56 are installed between the connecting rods 55.
[0032] In use, the pressure rod 34 is raised, and the toothed side of the timing belt is placed in the limiting groove 2 with the toothed side facing up, so that the pressure rod 34 is inserted into the timing belt loop. Then the pressure rod 34 is released, and the timing belt is pressed tightly onto the base 1 by the roller 1 35. Then the other part of the timing belt is put on the outside of the roller 2 56, and the timing belt is spread open by the sliding plate 52. The distance of the toothed side of the timing belt is measured by the distance measuring sensor 7. Since the distance between the distance measuring sensor 7 and the base 1 is fixed and known, the thickness of the timing belt can be obtained by subtracting the measured distance from the fixed distance. The distance measured by the distance measuring sensor 7 is displayed on the display screen 6. After one measurement, the user can rotate the timing belt to move the timing belt to different positions under the distance measuring sensor 7 to repeat the measurement.
[0033] In this embodiment, specifically, the limiting groove 2 includes a fixing plate 21, which is fixed above the base 1. A lead screw 23 is provided on one side of the fixing plate 21, and the lead screw 23 is threadedly connected to the upper side of the base 1. One end of the lead screw 23 is rotatably connected to the adjusting plate 22. By rotating the lead screw 23, the adjusting plate 22 can be moved, thereby adjusting the distance between the adjusting plate 22 and the fixing plate 21, which is suitable for synchronous belts of different widths.
[0034] In this embodiment, specifically, a guide rod 53 is fixedly connected to one end of the sliding plate 52. The guide rod 53 passes through both ends of the top plate 51. A second spring 54 is connected between the sliding plate 52 and both ends of the top plate 51, and the second spring 54 is located outside the guide rod 53. The guide rod 53 ensures that the sliding plate 52 and the top plate 51 are slidably connected. When the timing belt is sleeved outside the roller 56, it compresses the second spring 54, and the elastic force of the second spring 54 makes the timing belt taut.
[0035] In this embodiment, specifically, there is a gap between roller 2 56 and one end of connecting rod 55, and the gap of connecting rod 55 is greater than the width of roller 2 56. One end of connecting rod 55 limits the timing belt fitted on roller 2 56, preventing it from moving back and forth and detaching from roller 2 56.
[0036] In this embodiment, specifically, roller 35 and roller 56 are located on the same vertical plane.
[0037] In this embodiment, specifically, the width of roller 35 is greater than the spacing of the limiting groove 2.
