Technical Field

[0001] The utility model relates to the technical field of gear fixation, and specifically relates to a positioning structure for detecting the clearance of an arc gear. Background Technique

[0002] The arc gear is a common type of gear, and its gear tooth profile is in an arc shape. Compared with traditional spur gears, the arc gear can reduce the concentration of tooth surface load and the tooth surface contact stress during the transmission process, thereby improving the smoothness and service life of the gear transmission. After the arc gear is processed, it is necessary to use a gear clearance detection device to detect the clearance to ensure the normal operation of the gear transmission system. However, for existing gear clearance detection devices, in order to ensure the stability of the arc gear during clearance detection, the positioning operation of the arc gear is relatively cumbersome, thus reducing the detection efficiency.

[0003] In view of the above problems, the utility model proposes a positioning structure for detecting the clearance of an arc gear. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , in order to solve the problem that the positioning operation of the arc gear is relatively cumbersome, thereby reducing the detection efficiency, the following preferred technical solutions are provided:

[0021] A positioning structure for detecting the clearance of an arc gear, including a positioning processing table 1. A fixed block 2 is fixedly connected to the upper end of the positioning processing table 1. A movable block 3 is slidably connected to the upper end of the positioning processing table 1. A motor 4 is installed at one end of the fixed block 2 away from the movable block 3. A threaded rod 5 is threadedly connected to the inner wall of the movable block 3. One end of the threaded rod 5 is fixedly connected to the output end of the motor 4, and the other end of the threaded rod 5 is rotatably connected to a receiving block 6. A mounting disk 7 is rotatably connected to the upper end of the movable block 3. A positioning rod assembly 8 is fixedly connected to the center of the mounting disk 7. The positioning rod assembly 8 is used to sleeved the arc gear to be detected on the outer wall for positioning. The receiving block 6 is fixedly connected to the positioning processing table 1, and the receiving block 6 is used to abut against the positioning rod assembly 8.

[0022] The positioning rod assembly 8 includes an outer rod body 81 fixedly connected to the mounting disk 7 at one end. An inner cavity of the outer rod body 81 is slidably connected with a movable rod 82. One end of the movable rod 82 is fixedly connected with an external connection block 83. One end of the movable rod 82 away from the external connection block 83 is pivotally connected with a first push rod A84 and a second push rod A85. One end of the first push rod A84 away from the movable rod 82 is pivotally connected with a first positioning block 86. One end of the second push rod A85 away from the movable rod 82 is pivotally connected with a second positioning block 87. Openings are provided on both sides of the outer rod body 81. The first positioning block 86 and the second positioning block 87 are respectively slidably connected with the openings on both sides. One ends of the first positioning block 86 and the second positioning block 87 away from the first push rod A84 and the second push rod A85 are respectively pivotally connected with a first push rod B88 and a second push rod B89. The first positioning block 86 and the second positioning block 87 are both components made of rubber material, and an elastic element is fixedly connected between the first positioning block 86 and the second positioning block 87.

[0023] Specifically, when positioning the arc gear, just slip the arc gear over the positioning rod assembly 8. The driving motor 4 drives the threaded rod 5 to rotate, causing the movable block 3 to move on the upper wall of the positioning and machining table 1. The mounting plate 7 drives the positioning rod assembly 8 to approach the receiving block 6 until it abuts against the receiving block 6. At this time, the external block 83 will drive the movable rod 82 to move into the cavity of the outer rod body 81, increasing the angle between the first push rod A84 and the second push rod A85. Thus, in cooperation with the first push rod B88 and the second push rod B89, the first positioning block 86 and the second positioning block 87 are pushed out of the opening, and then the inner wall of the arc gear is firmly abutted by the first positioning block 86 and the second positioning block 87, achieving the purpose of efficient positioning. During the process of moving the arc gear to be detected into the detection range of the gap detection device, the positioning operation is extremely convenient, solving the problem that the positioning operation of the arc gear is relatively cumbersome, thus reducing the detection efficiency.

[0024] When the first positioning block 86 and the second positioning block 87 are pushed out of the opening, they will stretch the elastic element. Therefore, when releasing the positioning, just use the threaded rod 5 to drive the movable block 3 away from the receiving block 6, so that the external block 83 no longer acts on the first push rod A84 and the second push rod A85. At this time, through the reaction force of the tightened elastic element, the first positioning block 86 and the second positioning block 87 will be pulled back, and the positioning can be released.

[0025] Working principle: The driving motor 4 drives the threaded rod 5 to rotate, causing the movable block 3 to move on the upper wall of the positioning and machining table 1. The mounting plate 7 drives the positioning rod assembly 8 to approach the receiving block 6 until it abuts against the receiving block 6. At this time, the external block 83 will drive the movable rod 82 to move into the cavity of the outer rod body 81, increasing the angle between the first push rod A84 and the second push rod A85. Thus, in cooperation with the first push rod B88 and the second push rod B89, the first positioning block 86 and the second positioning block 87 are pushed out of the opening, and then the inner wall of the arc gear is firmly abutted by the first positioning block 86 and the second positioning block 87.
