Description

Technical Field

[0001] This utility model relates to the field of gear precision testing technology, specifically a gear precision testing device. Background Technology

[0002] Gears are a common type of gear transmission component, playing a crucial role in planetary and low-tooth-difference reducers with large transmission ratios. Therefore, the dimensions and precision of gear machining are extremely important, and the span distance of the gear's struts is even more critical dimensional data in gear design and manufacturing.

[0003] According to a publicly disclosed gear testing device (Announcement No.: CN219474496U), the design of the threaded groove, first slide groove, slide bar, abutment bar, wedge block, and gear body involves rotating a second screw inside the threaded groove. The rotation of the second screw compresses the wedge block, causing it to slide outwards. This causes the slide bar to slide within the first slide groove, which in turn causes the abutment bar to slide outwards. The abutment bar then contacts the inner wall of the gear body, completing its fixing operation. This allows the device to be used for positioning gear bodies of any size, enhancing its applicability and effectiveness.

[0004] However, in actual use, when fixing a new gear after the abutment has secured the gear, the abutment needs to be retracted to secure the gear again. This makes it take longer to fix different gears, thus reducing the testing efficiency of the device. In view of this, we propose a gear precision testing device. Utility Model Content

[0005] The purpose of this invention is to provide a gear precision testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear precision testing device, comprising a base, a translation motor fixedly connected to the outer wall of the base, the translation motor penetrating the outer wall of the base and fixedly connected to a lead screw, a slide block being drivenly connected to the outer wall of the lead screw, a detection component being provided on the upper outer wall of the slide block, a detection rod being provided on the outer wall of the detection component, a test gear being provided on the outer wall of the base, and a fixing component being provided inside the base for fixing test gears of different sizes, the fixing component comprising:

[0007] A fixed motor is fixedly connected to the inner wall of the base. A fixed housing is fixedly connected to the output end of the fixed motor. An electric push rod is fixedly connected to the inner wall of the fixed housing. A fixed block is slidably connected through the outer wall of the fixed housing.

[0008] A hinge plate is hinged to the upper outer wall of a fixed block. A fixed disc is hinged to the end of the hinge plate away from the fixed block. A sliding rod is slidably connected through the outer wall of the fixed disc, and a spring is sleeved on the outer wall of the sliding rod.

[0009] Preferably, the base is provided with a pressure assembly that can press the test gear down. The pressure assembly includes a fixed seat, which is fixedly connected to the outer wall of the base. A screw is fixedly connected to the upper outer wall of the fixed seat. A nut is threadedly connected to the outer wall of the screw. A limit block is fixedly connected to the outer wall of the nut. A rotating shell is rotatably connected to the outer wall of the nut. A pressure plate is fixedly connected to the outer wall of the rotating shell. After the fixed block fixes the test gear, the nut can be rotated to drive the pressure plate to press on the test gear, thus blocking the position where the test gear is fixed to the fixed block.

[0010] Preferably, the inner wall of the rotating shell is provided with a limiting groove, the limiting block is rotatably connected to the inner wall of the limiting groove, and the pressure plate is in contact with the upper end of the test gear and is slidably connected to the outer wall of the fixed shell. When the nut is rotated to make the nut rotate and move on the screw, the rotation of the nut can be made to not affect the downward movement of the pressure plate.

[0011] Preferably, the fixed disk is slidably connected to the inner wall of the fixed shell, one end of the spring is fixedly connected to the outer wall of the fixed disk, and the other end of the spring is fixedly connected to the inner wall of the fixed shell. The spring can cause the fixed disk to move upward, so that the fixed disk can drive the hinge plate to rotate.

[0012] Preferably, the end of the fixed block near the electric push rod is formed with an arc surface, and the output end of the electric push rod is formed with an arc surface. The arc surface of the output end of the electric push rod contacts the arc surface of the fixed block. When the electric push rod extends, it can push the fixed block to extend, and at this time the fixed block can contact the inner wall of the test gear.

[0013] Preferably, a friction pad is provided at the end of the fixed block away from the electric push rod. The friction pad of the fixed block contacts the inner wall of the test gear. When the fixed block contacts the inner wall of the test gear, the friction between the fixed block and the inner wall of the test gear through the friction pad is relatively large.

[0014] Preferably, the fixed shell is fixedly connected to the inner wall of the base, the test gear is in contact with the outer wall of the fixed shell, and the test gear is located between the fixed shell and the pressure plate. When the pressure plate is in contact with the fixed shell, the pressure plate can limit the test gear so that the test gear will not come loose from the fixed block, thereby allowing the test gear to be stably driven to rotate by the fixed component.

[0015] Compared with the prior art, the present invention provides a gear precision testing device, which has the following beneficial effects:

[0016] 1. This gear precision testing device, by placing the test gear on the fixed housing, allows the electric push rod to extend and push the fixed block to extend, thus fixing the test gear. When the fixed motor rotates, the fixed housing can drive the test gear to rotate, allowing the testing rod to test different positions of the test gear. After the test gear is tested and removed, the electric push rod returns to its original position. At this time, the spring can move the fixed plate upward, causing the hinge plate to rotate and drive the fixed block to retract into the fixed housing, making it convenient for the fixed block to fix the next set of gears.

[0017] 2. This gear precision testing device, when testing the test gear, allows the nut to be rotated, causing the rotating shell to move the pressure plate downward. This blocks the position where the test gear is fixed to the fixed block, preventing foreign objects from entering, while also limiting the test gear, making it less likely to loosen from the fixed shell, and ensuring that the test gear can be tested stably.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a gear precision testing device, including a base 1, a translation motor 2 fixedly connected to the outer wall of the base 1, the translation motor 2 passing through the outer wall of the base 1 and fixedly connected to a lead screw 3, a slide block 4 being drivenly connected to the outer wall of the lead screw 3, a detection component 5 being provided on the upper outer wall of the slide block 4, a detection rod 6 being provided on the outer wall of the detection component 5, a test gear 7 being provided on the outer wall of the base 1, and a fixing component 8 being provided inside the base 1 for fixing test gears 7 of different sizes, the fixing component 8 including a fixing motor 81, a fixing shell 82, an electric push rod 83, a fixing block 84, a hinge plate 85, a fixing disc 86, a slide rod 87, and a spring 88.

[0024] In one embodiment of this utility model, a fixed motor 81 is fixedly connected to the inner wall of the base 1, a fixed housing 82 is fixedly connected to the output end of the fixed motor 81, an electric push rod 83 is fixedly connected to the inner wall of the fixed housing 82, and a fixed block 84 is slidably connected through the outer wall of the fixed housing 82.

[0025] In one embodiment of the present invention, the hinge plate 85 is hinged to the upper outer wall of the fixed block 84, and a fixed plate 86 is hinged to the end of the hinge plate 85 away from the fixed block 84. A slide rod 87 is slidably connected through the outer wall of the fixed plate 86, and a spring 88 is sleeved on the outer wall of the slide rod 87.

[0026] In addition, a pressure component 9 is provided on the outside of the base 1 to press down the test gear 7. The pressure component 9 includes a fixed seat 91, which is fixedly connected to the outer wall of the base 1. A screw 92 is fixedly connected to the upper outer wall of the fixed seat 91. A nut 93 is threadedly connected to the outer wall of the screw 92. A limit block 94 is fixedly connected to the outer wall of the nut 93. A rotating shell 95 is rotatably connected to the outer wall of the nut 93. A pressure plate 96 is fixedly connected to the outer wall of the rotating shell 95. After the fixed block 84 fixes the test gear 7, the nut 93 can be rotated to drive the pressure plate 96 to press down on the test gear 7, so that the position where the test gear 7 is fixed to the fixed block 84 is blocked, and the pressure plate can also press down on the test gear 7, so that the test gear 7 is not easy to loosen on the fixed shell 82.

[0027] In an embodiment of this utility model, a limiting groove is provided on the inner wall of the rotating shell 95, the limiting block 94 is rotatably connected to the inner wall of the limiting groove, and the pressure plate 96 is in contact with the upper end of the test gear 7 and is slidably connected to the outer wall of the fixed shell 82. When the nut 93 is rotated to make the nut 93 rotate and move on the screw 92, the rotation of the nut 93 can not affect the downward movement of the pressure plate 96, so that the pressure plate 96 can stably limit the test gear 7.

[0028] In this embodiment of the utility model, the fixed disk 86 is slidably connected to the inner wall of the fixed shell 82, one end of the spring 88 is fixedly connected to the outer wall of the fixed disk 86, and the other end of the spring 88 is fixedly connected to the inner wall of the fixed shell 82. The spring 88 can move the fixed disk 86 upward, so that the fixed disk 86 can drive the hinge plate 85 to rotate, so that the hinge plate 85 can drive the fixed block 84 to be stored in the fixed shell 82, which facilitates the fixed block 84 to fix the next set of gears.

[0029] In an embodiment of this utility model, the end of the fixing block 84 near the electric push rod 83 is formed as an arc surface, and the output end of the electric push rod 83 is formed as an arc surface. The arc surface of the output end of the electric push rod 83 contacts the arc surface of the fixing block 84. When the electric push rod 83 extends, it can push the fixing block 84 to extend. At this time, the fixing block 84 can contact the inner wall of the test gear 7. Different extension distances of the electric push rod 83 can enable the fixing block 84 to fix test gears 7 of different sizes.

[0030] In an embodiment of this utility model, a friction pad is provided at the end of the fixing block 84 away from the electric push rod 83. The friction pad of the fixing block 84 contacts the inner wall of the test gear 7. When the fixing block 84 contacts the inner wall of the test gear 7, the friction between the fixing block 84 and the inner wall of the test gear 7 through the friction pad is large, so that the test gear 7 can be fixed more stably by the fixing block 84.

[0031] In this embodiment of the utility model, the fixed shell 82 is fixedly connected to the inner wall of the base 1, the test gear 7 is in contact with the outer wall of the fixed shell 82, and the test gear 7 is located between the fixed shell 82 and the pressure plate 96. When the pressure plate 96 is in contact with the fixed shell 82, the pressure plate 96 can limit the test gear 7 so that the test gear 7 will not be loosened from the fixed block 84, so that the test gear 7 can be stably driven to rotate by the fixed component 8, and the test gear 7 can be fully detected by the detection rod 6.

[0032] In this invention, during use, starting the translation motor 2 causes the lead screw 3 to rotate, which in turn moves the slide block 4. This allows the detection component 5 to be moved by the slide block 4, enabling the detection rod 6 to fix test gears 7 of different diameters. The test gear 7 can then be placed on the fixing shell 82. The electric push rod 83 extends, pushing the fixing block 84 to extend, allowing the fixing block 84 to contact the inner wall of the test gear 7 and fix it. When the fixing motor 81 rotates, the fixing shell 82 causes the test gear 7 to rotate, allowing the detection rod 6 to detect different positions of the test gear 7. After being removed, the electric actuator 83 resets. At this time, the spring 88 can move the fixed plate 86 upward, so that the fixed plate 86 can drive the hinge plate 85 to rotate and drive the fixed block 84 to be stored in the fixed shell 82. This makes it convenient for the fixed block 84 to fix the next set of gears. When testing the test gear 7, the nut 93 can be rotated so that the nut 93 drives the pressure plate 96 to press on the test gear 7. This blocks the position where the test gear 7 is fixed to the fixed block 84, preventing foreign objects from entering and limiting the test gear 7. This makes it difficult for the test gear 7 to loosen on the fixed shell 82, so that the test gear 7 can be tested stably.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
