Technical Field
[0001] This utility model relates to the field of testing tooling technology, and in particular to a tooling for testing the angle of a gear shaft swing arm. Background Technology
[0002] The gear shaft swing arm angle detection fixture is a clamping device for detecting gear shaft swing arms. It allows for the fixing of the gear shaft swing arm angle, thus enabling the detection of the swing arm shaft on the gear shaft.
[0003] Traditional gear shaft swing arm angle measuring fixtures often use V-blocks to lock the gear shaft swing arm. This locking method is cumbersome and inconvenient for users to inspect the swing arm shaft. Therefore, a more user-friendly gear shaft swing arm angle measuring fixture is needed. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gear shaft rocker arm angle detection fixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gear is fixedly sleeved on the gear shaft, and mounting slots are provided on the mounting plates, and the mounting slots are all adapted to the gear shaft.
[0008] Each clamp is equipped with a push rod, and a positioning component is fixedly installed at the end of each push rod. The positioning component is adapted to the gear.
[0009] In addition, a preferred structure is that each of the clamps is movably provided with a handle, and the handle is connected to the push rod via a rocker arm.
[0010] In addition, a preferred structure is that a fixed seat is fixedly provided on the base, and the fixed seat has multiple guide cavities, and the push rods are adapted to pass through the guide cavities.
[0011] Furthermore, in a preferred configuration, each end of the push rod is fixedly equipped with an anti-detachment component, and the diameter of the anti-detachment component is larger than the diameter of the guide cavity.
[0012] Furthermore, in a preferred configuration, each of the anti-detachment components is equipped with a positioning component, and the positioning component is adapted to the tooth groove on the gear.
[0013] Furthermore, in a preferred configuration, a rocker arm is fixedly sleeved on the gear shaft, and the other end of the rocker arm is rotatably inserted into a rocker arm shaft.
[0014] The beneficial effects of this utility model are as follows: by locking and clamping the gear with the positioning component, the gear shaft and the swing arm can be fixed, so that the swing arm shaft can be stably rotated at the bottom of the dial indicator. Thus, the rotation of the swing arm shaft can be achieved through the dial indicator. This positioning method of the gear shaft and the swing arm is simple and quick, and convenient for users to operate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 The gear shaft swing arm angle detection fixture includes a base 1. Multiple clamps 2 are fixedly mounted on one side of the top of the base 1. A dial indicator 61 is mounted on the other side of the top of the base 1 via a fixing bracket 6. Mounting plates 4 are provided on both sides of the base 1 below the fixing bracket 6. A gear 51 is fixedly fitted onto the gear shaft 5. Mounting slots 41 are provided on each mounting plate 4, and each slot 41 is adapted to the gear shaft 5. Push rods 22 are provided on each clamp 2, and positioning elements 24 are fixedly mounted on the ends of each push rod 22, and each positioning element 24 is adapted to the gear 51.
[0023] Each clamp 2 is movably equipped with a handle 21, and each handle 21 is connected to the push rod 22 via a rocker arm. The user can easily push and pull the handle 21 to extend and retract the push rod 22. It is worth noting that this is prior art and not part of the technical problem of facilitating the positioning of the gear shaft 5 required by this technical solution; therefore, it will not be elaborated upon further in this utility model.
[0024] The base 1 is fixedly equipped with a fixing seat 3, which has multiple guide cavities 31, and the push rod 22 is adapted to pass through the guide cavities 31. The guide cavities 31 guide the push rod 22 to improve its stability during movement.
[0025] Each push rod 22 has an anti-detachment component 23 fixedly installed at its end, and the diameter of the anti-detachment component 23 is larger than the diameter of the guide cavity 31. The anti-detachment component 23 prevents the push rod 22 from falling out of the guide cavity 31.
[0026] Each of the anti-detachment components 23 is equipped with a positioning component 24, and the positioning component 24 is adapted to the tooth groove on the gear 51. By setting the positioning component 24, the gear 51 can be positioned, thereby simultaneously positioning the gear shaft 5 and the rocker arm 52.
[0027] Among them, a swing arm 52 is fixedly sleeved on the gear shaft 5, and the other end of the swing arm 52 is rotatably inserted with a swing arm shaft 53.
[0028] In this embodiment, when the user needs to inspect the swing arm shaft 53, they only need to install both ends of the gear shaft 5 into the mounting slots 41 on the mounting plate 4. Then, the gear shaft 5 is rotated to drive the swing arm 52 on the gear shaft 5 to rotate below the dial indicator 61. At this time, the swing arm shaft 53 will automatically be located at the bottom of the dial indicator 61.
[0029] The user then simply pulls handle 21 to move push rod 22 outward. This causes positioning piece 24 on push rod 22 to engage with the tooth groove on gear 51, thus fixing gear shaft 5, gear 51, and rocker arm 52. At this point, rocker arm shaft 53 is stably positioned at the bottom of dial indicator 61. The user can then rotate rocker arm shaft 53 while using dial indicator 61 to inspect it. It is worth noting that the specific inspection method using dial indicator 61 is existing technology and will not be elaborated upon further.
[0030] Furthermore, once the user has completed the inspection of the swing arm shaft 53, they only need to pull the handle 21 in the opposite direction to automatically retract the push rod 22, at which point the user can directly remove the gear shaft 5.
[0031] Furthermore, the base 1 in this application is provided with two clamps 2 because the position of the gear 51 on the gear shaft 5 is not fixed, but changes depending on the specifications of the gear shaft 5. By setting the two clamps 2, the positioning member 24 on this device can lock and clamp most of the gears 51.
[0032] In this invention, the gear shaft 5 and the rocker arm 52 can be fixed by locking and clamping the gear 51 with the positioning member 24, so that the rocker arm shaft 53 can be stably rotated at the bottom of the dial indicator 61. Thus, the rotation of the rocker arm shaft 53 can be achieved through the dial indicator 61. This positioning method of the gear shaft 5 and the rocker arm 51 is simple and quick, and convenient for users to operate.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
