Technical Field
[0001] This utility model belongs to the technical field of gear detection devices, specifically relating to a gear runout detection device. Background Technology
[0002] Gears are important mechanical components in industrial production. After gear production, a series of precision tests are required. Among these tests, gear runout detection mainly involves detecting the radial error of the gear. Currently, precision instruments such as radial runout meters that can achieve accurate measurement occupy a large area and are expensive. Manual measurement, on the other hand, is prone to significant errors due to the large workload and cumbersome operation. Therefore, simplifying the operation of gear runout detection devices and saving measurement time is an important research direction for improving the efficiency of manual measurement. Utility Model Content
[0003] To address the aforementioned problems, this utility model aims to provide a gear runout detection device with a simple structure, low production cost, easy operation, convenient gear assembly and disassembly, and applicability to runout detection of various gear specifications. Compared to traditional manual detection, simply rotating the roller is sufficient to rotate the gear through transmission, eliminating the need for manual gear manipulation. This allows users to focus on reading the dial indicator, saving measurement time and simplifying the measurement process.
[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A gear runout detection device includes a base, a fixing mechanism, a support mechanism, a measuring mechanism, and a gear to be measured. The fixing mechanism includes a handle assembly, a main shaft, and a quick-release assembly. The handle assembly is used to drive the main shaft to move axially.

The mounting shaft passes through the second mounting hole, and a fixing part is provided at the other end of the mounting shaft. The fixing part and the mounting seat form a one-way limiting lock.
[0008] The measuring mechanism includes a measuring instrument, a probe, and a pressure rod. The measuring instrument and the probe are installed together and located on the pressure rod, which is hinged to the base.
[0009] It also includes a limiting block, which is located at the bottom of the pressure rod. When the pressure rod swings to contact the limiting block, the probe is parallel to the radial direction of the gear.
[0010] The lever is also equipped with a control lever, which is used to swing the lever.

Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0016] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0017] Combined with appendix Figures 1 to 3 As shown, this embodiment discloses a gear runout detection device, including a base, a fixing mechanism 1, a support mechanism 2, a measuring mechanism 3, and a gear 4 to be measured. The fixing mechanism 1 includes a handle assembly 11, a main shaft 12, and a quick-release assembly 13. The handle assembly 11 is used to drive the main shaft 12 to move axially. The handle assembly 11 is provided with a pusher 113. One end of the main shaft 12 is provided with a groove surface 121, and the end of the pusher 113 cooperates with the groove surface 121. One end of the quick-release assembly 13 is provided with a mounting shaft 131, and the gear 4 is sleeved on the mounting shaft 131. The other end of the main shaft 12 is provided with a first mounting hole, and the mounting shaft 131 is installed in cooperation with the first mounting hole. The support mechanism 2 includes a plurality of support seats 21, and a plurality of rollers 22 are provided on the support seats 21. The lower part of the main shaft 12 abuts against the plurality of rollers 22.
[0018] In this embodiment, based on the above, there are two support bases 21, each with two rollers 22. The two rollers 22 are located on the left and right sides of the lower part of the main shaft 12, respectively. The rollers 22 are manually rotated; rotating either roller 22 will drive the main shaft 12 to rotate, which in turn drives the gear 4 to rotate. In other embodiments, the rollers 22 may also be electrically driven.
[0019] In conjunction with the above, the handle assembly 11 also includes a crank handle 111 and a connecting part 112. The crank handle 111 includes a bend portion 1111, and the two ends of the connecting part 112 are respectively fitted with the bend portion 1111 and the push top 113. In this embodiment, the connecting part 112 includes two connecting pieces, which are hinged to the bend portion 1111. When the crank handle 111 is turned, the bend portion 1111 swings, causing the connecting part 112 and the push top 113 to move, thereby pushing the main shaft 12 towards the quick-release assembly 13 or releasing the fixation between the main shaft 12 and the gear 4.
[0020] In conjunction with the above, in other embodiments, the crank handle 111 and the connecting part 112 may also adopt a push rod and slide groove structure to push the push top 113 to move along the axial direction of the main shaft 12.
[0021] In combination with the above, in this embodiment, the end of the push top 113 is spherical and the groove surface 121 is spherical, which is beneficial to the docking between the push top 113 and the main shaft 12, and avoids sliding misalignment and reduces wear; in other embodiments, other shapes commonly used in the prior art can also be used.
[0022] In conjunction with the above, the base is provided with a mounting seat 5, and the mounting seat 5 is provided with a second mounting hole that cooperates with the mounting shaft 131. The mounting shaft 131 passes through the second mounting hole, and a fixing part 132 is provided at the other end of the mounting shaft 131. The fixing part 132 and the mounting seat 5 form a one-way limiting lock. The fixing part 132 and the mounting shaft 131 can adopt an integral molding or split molding structure. Preferably, in this embodiment, several fastening pads 133 can also be provided on the mounting shaft 131. When the thickness of the gear 4 to be measured is relatively thin, it can help to fix the gear 4.
[0023] In combination with the above, in another preferred embodiment, the mounting shaft 131 can also be located at the end of the main shaft 12. After the mounting shaft 131 passes through the gear 4 and the second mounting hole, it is locked by the fixing part 132.
[0024] In combination with the above, the measuring mechanism 3 includes a measuring gauge 31, a probe 32, and a pressure rod 33. The measuring gauge 31 and the probe 32 are installed together and are located on the pressure rod 33. The pressure rod 33 is hinged to the base. It also includes a limiting block 34, which is located at the lower part of the pressure rod 33. When the pressure rod 33 swings to contact the limiting block 34, the probe 32 is parallel to the radial direction of the gear 4. The pressure rod 33 is also provided with a control lever 331, which is used to make the pressure rod 33 swing.
[0025] In the preferred embodiment, based on the above installation structure, the measuring mechanism 3 is located above the gear 4. The measuring gauge 31 is preferably a dial indicator. The measuring gauge 31 and the probe 32 are located on opposite sides of the pressure rod 33 and are connected and installed inside the pressure rod 33. This allows the measuring gauge 31 to display the displacement reading when the probe 32 is displaced. Normally, the bottom of the probe 32 is located within the tooth groove of the gear 4. When the gear 4 rotates, the teeth of the gear 4 abut against the probe 32, causing the probe 32 to move upwards. After the teeth have rotated past the probe 32, the probe 32 resets, and this cycle repeats. In other embodiments, the measuring mechanism 3 can also be located on the side of the gear 4, or in other positions.
[0026] With the above-described mounting structure, the center of the push top 113, the main shaft 12, the gear 4, and the mounting shaft 131 is located on the same axis.
[0027] Based on the above, the working process of this utility model is as follows: Insert the mounting shaft 131 of the quick-installation assembly 13 into the second mounting hole of the mounting base 5 until the fixing part 132 abuts against the mounting base 5. According to the thickness of the gear 4 to be measured, put an appropriate amount of fastening pad 133 and gear 4 on the mounting shaft 131. Hold the operating lever 331 to make the pressure rod 33 abut against the limiting block 34, so that the gear 4 is located below the probe 32. Place the main shaft 12 on the support mechanism 2, and turn the crank handle 111 to push the push top 113 to move the main shaft 12 toward the quick-installation assembly 13. During the movement, the mounting shaft 131 is inserted into the first mounting hole at the end of the main shaft 12 until the end of the main shaft 12 is in close contact with the gear 4. Then rotate the roller 22 to make the main shaft 12 drive the gear 4 to rotate. During the rotation of the gear 4, the probe 32 is continuously displaced. During this process, the reading of the measuring instrument 31 is read. After the gear 4 rotates one revolution, the range value of each measurement is calculated, that is, the gear runout.
[0028] This utility model has a simple structure, low production cost, simple operation process, convenient gear disassembly and assembly, and is applicable to the runout detection of various gears of different specifications. Compared with traditional manual detection, it only requires rotating the roller to make the gear rotate through transmission, without the need for manual gear manipulation. This allows users to focus on reading the readings on the meter, saving measurement time and simplifying the measurement process.
[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
