Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and more specifically to an inspection tool for measuring the distance between the shaft edge and the hole of a pedal shaft. Background Technology

[0002] Bicycles and electric bicycles are common modes of transportation. During use, the pedals are perpendicular to the bicycle frame and connected by a pedal axle. Therefore, the precision of the pedal axle affects the fit between the pedals and the frame, and directly impacts performance and safety. Figure 1 The pedal shaft shown has fixed standard requirements for the spacing between the three positioning holes for installation and the shaft edge of the pedal shaft connecting section connected to the foot pedal. Manual measurement or instrument measurement cannot effectively reference the positioning of the three positioning holes for accurate measurement, resulting in low measurement efficiency and inaccurate accuracy. At the same time, it is impossible to achieve synchronous measurement of the three holes and the shaft edge.

[0003] To address the aforementioned issues, commercially available gauges for detecting multiple inner hole positions and hole center distances, such as the Chinese patent CN218822022U entitled "A Gauge for the Position Measurement of Three Holes in an Axle," include a measuring body. A connecting cylinder is fixedly connected to the left side of the measuring body. A center pin is movably connected to the inner cavity of the measuring body and the connecting cylinder. A connecting groove is formed on the left side of the center pin, and a threaded sleeve is fixedly connected to the inner cavity of the connecting groove. A connecting handle is provided on the left side of the center pin, and a connecting hole is formed on the right side of the inner cavity of the connecting groove. This gauge clearly cannot simultaneously meet the requirements for... Figure 1 The detection of the distance between the shaft edge of the pedal shaft and multiple hole positions necessitates the configuration of a simple yet effective inspection tool. Utility Model Content

[0004] In response to the above situation, in order to overcome the problems of low efficiency and inaccuracy in the existing pedal shaft hole and shaft edge detection, and the inability to simultaneously measure the distance between the three holes and the shaft edge, the purpose of this utility model is to provide a tool that can simultaneously detect the distance between the three holes and the shaft edge, so as to meet the standard requirements for the distance between the three positioning holes and the shaft edge. At the same time, it has a simple structure and convenient measurement process, which can improve both the production efficiency and detection accuracy of the pedal shaft.

[0005] To achieve the above objectives, the technical solution of this utility model is:

[0006] A gauge for measuring the distance between the edge of a pedal shaft and a hole includes a testing base detachably fixed to a testing clamp. The testing base contains a plug assembly and a measuring hole. The plug assembly has three plugs, the positions of which are opposite to the positioning holes of the pedal shaft. The measuring hole is located at the center of the testing base and corresponds to and fits into the connecting section of the pedal shaft. The measuring hole can be used for the fitting and positioning of the connecting section of the pedal shaft. Simultaneously, by using the three plugs of the plug assembly to test the three positioning holes of the pedal shaft, the accuracy of the distance between the positioning holes and the edge of the connecting section of the pedal shaft can be precisely measured.

[0007] Preferably, the detection base has a pin hole; the pin hole can be used to install and remove the plug pin.

[0008] Preferably, there are three pin holes, and the positions of the three pin holes correspond to the three positioning holes of the pedal shaft.

[0009] Preferably, the plug pin is inserted into the pin hole, and the pin hole and the plug pin are compatible with each other; in this way, even if the plug pin is worn or deformed, the entire gauge can be replaced in time for normal use.

[0010] Preferably, the measuring hole is a through hole that penetrates the detection base, which is convenient for processing and can ensure the dimensional accuracy of the measuring hole.

[0011] Preferably, the corners of the measuring hole are provided with semi-circular holes, which are more suitable for precise insertion of the pedal shaft connection section during testing.

[0012] Preferably, the detection base has one bolt hole on each of its four sides, and the bolt holes are used to fix the detection base.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] (1) This utility model sets a plug pin assembly and a measuring hole in the detection base respectively, and uses the connecting section of the pedal shaft to be inserted into the measuring hole for limiting. Thus, the three plug pins of the plug pin assembly are used to detect the three positioning holes of the pedal shaft at the same time, which can accurately measure the distance between the positioning hole and the shaft edge of the connecting section of the pedal shaft.

[0015] (2) By setting plug pin components and measuring holes in the detection base, the detection of the pedal shaft connection section is required to be inserted into the measuring hole, and the three plug pins are inserted into the positioning hole of the pedal shaft. This ensures that the distance between the three positioning holes of the pedal shaft and the shaft edge of the connection section is accurately detected, and ensures that the shaft edge distance of the three positioning holes meets the standard. This completely avoids the problem of the difference in the shaft edge distance of the three holes caused by the error of manual measuring tool detection. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0027] This embodiment describes a gauge for measuring the distance between the edge of the pedal shaft and the hole. (See attached document.) Figures 2 to 4As shown, it includes a testing base 2 detachably and fixedly connected to the testing clamp. The testing base 2 is provided with a plug pin assembly 20 and a measuring hole 21. The plug pin assembly 20 consists of three plug pins 20a, which are arranged opposite to the positioning hole 1c of the pedal shaft 1. The diameter of the plug pins 20a is adapted to the diameter of the positioning hole 1c of the pedal shaft 1. The measuring hole 21 is opened at the center of the testing base 2 and corresponds to and is adapted to the connecting section 1a of the pedal shaft 1. The measuring hole 21 can be used for the adaptation and positioning of the connecting section 1a of the pedal shaft 1. At the same time, the three positioning holes of the pedal shaft 1 can be tested by the three plug pins 20a of the plug pin assembly 20, and the accuracy of the distance between the positioning hole and the shaft edge 1b of the connecting section 1a of the pedal shaft 1 can be accurately measured.

[0028] For further technical optimization solutions, please refer to Figure 3 As shown, the testing base 2 has pin holes 20b; the pin holes 20b can be used to install and remove the plug pin 20a, and there are 3 pin holes 20b. The positions of the 3 pin holes 20b correspond to the 3 positioning holes 1c of the pedal shaft 1. At the same time, the plug pin 20a is inserted into the pin holes 20b, and the pin holes 20b and the plug pin 20a are compatible with each other. In this way, even if the plug pin 20a is worn or deformed, the entire inspection tool can be replaced in time for normal use.

[0029] For more specific technical optimization solutions, please refer to Figure 3 and Figure 4 As shown, the measuring hole 21 is a through hole that passes through the detection base 2, which is convenient for processing and can ensure the dimensional accuracy of the measuring hole 21. The corners inside the measuring hole 21 are provided with semi-circular holes 21a, which are more suitable for the precise insertion of the connecting section 1a of the pedal shaft 1 during testing. There is a bolt hole 22 on each of the four sides of the detection base 2, which is used to fix the detection base 2.

[0030] When the inspection tool of this utility model is used to inspect the pedal shaft 1, refer to... Figures 2 to 7 As shown, first, the pedal shaft 1 is inverted, and the connecting section 1a of the pedal shaft 1 is inserted downwards into the corresponding measuring hole 21, fitting together to form a positioning. Using this as a reference, the three positioning holes 1c are measured. At the same time, the connecting section 1a of the pedal shaft 1 continues downwards along the measuring hole until the three positioning holes 1c and the three plug pins 20a in the pedal shaft 1 are fully fitted together. The test is then completed. This shows that the distance between the shaft edge 1b of the connecting section 1a of the pedal shaft 1 and the three positioning holes 1c all meet the accuracy standard requirements. If any one of the plug pins 20a in the plug pin assembly 20 cannot be inserted into the pin hole 20b, it can be seen that the distance between the positioning hole 1c of the pedal shaft 1 and the shaft edge 1b of the connecting section 1a does not meet the dimensional requirements. This ensures that the distance between the three positioning holes of the pedal shaft 1 and the shaft edge 1b of the connecting section 1a is accurately measured, ensuring the consistency of the standard distance between the three holes and the shaft edge 1b. This completely avoids the problem of differences in the distance between the three holes and the shaft edge 1b caused by errors in manual measuring tools.

[0031] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
