Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection technology, and in particular to a pneumatic path conversion device for measuring bearing inner diameter and right angle. Background Technology

[0002] The inner diameter and right angle of tubular workpieces are important standards for judging whether the workpieces are compliant. However, the common method of measuring the inner diameter and right angle is to manually hold the workpiece and measure it, which is slow. In order to improve efficiency, existing technologies also use pneumatic measuring instruments to measure the inner diameter and right angle by measuring the pressure and intensity of the air output by the pneumatic measuring instrument.

[0003] The measurement technology of the pneumatic measuring instrument for transmission involves using two sets of measuring instruments to measure the bearing inner diameter and the right angle. The operator performs two measurement actions. In order to improve work efficiency, it is first prepared to measure the inner diameter and right angle directly through one set of measuring instruments. However, when measuring through one set of measuring instruments, it is necessary to switch the air path of the pneumatic measuring instrument through the air path conversion device.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-4As shown, the present invention proposes a bearing inner diameter and right angle measurement air circuit conversion device, including a mounting box 1 with an opening at the top. The mounting box 1 is equipped with multiple solenoid valves 10. One end of the mounting box 1 is provided with multiple mounting holes, and mounting components can be detachably installed in each of the mounting holes. One end of the solenoid valve 10 is provided with an air intake component for air intake, which is detachably connected to the mounting hole through the mounting component. The other end of the solenoid valve 10 is provided with an air outlet component for air outlet, which is detachably connected to the mounting hole through the mounting component.

[0025] This technical solution connects the air intake and exhaust components to multiple solenoid valves 10 via detachable mounting components. The solenoid valves 10 connect the air intake and exhaust components to achieve measurement. The multiple mounting holes and mounting components make the air path layout more flexible. The air intake and exhaust components can be quickly disassembled and assembled via the mounting components, improving maintenance efficiency. By controlling the opening and closing of multiple solenoid valves 10, the solution can effectively control the opening and closing of the air path to achieve air path conversion, thus fulfilling the necessary conditions for simplifying the measurement process and effectively improving the efficiency of measuring workpieces.

[0026] Furthermore, this application also proposes that the mounting assembly includes a mounting plate 3 and an air intake pipe 4. The mounting plate 3 is located at the mounting hole and fits against the outer end of the mounting box 1. The mounting plate 3 is provided with a first through hole, and the air intake pipe 4 is fixedly installed in the first through hole. The mounting plate 3 is detachably connected to the mounting box 1, and the air intake pipe 4 is connected to and communicates with the air intake assembly.

[0027] Therefore, this technical solution achieves rapid disassembly and assembly of the air circuit connection through modular design. The mounting plate 3 serves as a transition component, which not only ensures the accurate positioning of the air intake pipe 4, but also simplifies the maintenance process.

[0028] Furthermore, this application also proposes that the mounting plate 3 is provided with two mounting holes spaced apart, the mounting box 1 is provided with a first threaded through hole communicating with the mounting holes, a bolt is provided in the mounting hole, the bolt extends into the first threaded through hole and is threadedly connected to the mounting box 1, and the bolt can be moved to abut against the mounting plate 3.

[0029] Thus, this technical solution achieves a detachable connection between the mounting plate 3 and the mounting box 1 through the cooperation of bolts and threaded through holes.

[0030] Furthermore, this application also proposes that the air intake assembly includes an air guide block 5, which is connected to and fitted to the mounting plate 3. One end of the air guide block 5 facing the mounting plate 3 is provided with a first groove, and the air intake pipe 4 extends into the first groove. The other end of the air guide block 5 is provided with a plurality of air outlets that communicate with the first groove. A first connecting pipe is provided in the air outlet. The plurality of first connecting pipes are equal in number to the plurality of solenoid valves 10 and correspond one-to-one. The plurality of first connecting pipes are respectively connected to the air intake end of the solenoid valve 10 and communicate with each other.

[0031] This technical solution achieves centralized gas distribution through the gas guide block 5, diverting a single gas source to multiple solenoid valves 10. After the gas enters the first groove through the inlet pipe 4, it is delivered to the corresponding solenoid valve 10 through multiple outlet holes and the first connecting pipe.

[0032] Furthermore, this application also proposes that the air outlet assembly includes an air distribution pipe 6, a sealing plate 7, and an air guide pipe 8. The air distribution pipe 6 is connected to the mounting plate 3 and communicates with the air inlet pipe 4. The end of the air distribution pipe 6 away from the mounting plate 3 is provided with the sealing plate 7. The sealing plate 7 is provided with two air guide holes. The air guide pipe 8 is disposed in the air guide holes and is sealed and connected to the sealing plate 7. The air guide pipe 8 is provided with a second connecting pipe. The number of the multiple second connecting pipes is equal to the number of the multiple solenoid valves 10 and they correspond one-to-one. The end of the second connecting pipe away from the air guide pipe 8 is connected to the air outlet end of the solenoid valve 10 and communicates with each other.

[0033] In response, this technical solution centrally distributes the gas through the gas distribution pipe 6, and then distributes it to each solenoid valve 10 through the gas guide hole on the sealing plate 7, thereby achieving orderly control of gas output.

[0034] Furthermore, this application also proposes a technical solution including a cover plate 2, which is placed inside the mounting box 1 and seals the mounting box 1.

[0035] This technical solution effectively solves the problem of protecting the internal components of the measuring instrument by adding a cover plate 2. Since airflow disturbances occur during pneumatic measurement, the sealing effect of the cover plate 2 prevents external dust from entering the mounting box 1, while also preventing internal airflow leakage from affecting measurement accuracy.

[0036] Furthermore, this application also proposes that the side wall of the mounting box 1 is provided with a vent hole, and the ventilation fan 9 is disposed in the vent hole and connected to the mounting box 1.

[0037] This technical solution effectively solves the problem of heat accumulation generated during the operation of the solenoid valve 10 by installing an exhaust fan 9 on the side wall of the mounting box 1.

[0038] The system includes 16 solenoid valves 10, four air guide blocks 5, each with four air outlets, and eight air distribution pipes 6. This allows for the measurement of the workpiece's inner diameter and right angle using different air paths, thereby improving measurement accuracy.

[0039] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
