Description

Technical Field

[0001] This utility model relates to the field of quality inspection equipment technology, specifically a gear machining accuracy testing device. Background Technology

[0002] Gears, as a common precision mechanical structure, have wide applications in the mechanical field, especially in mechanical transmission systems. Gear precision, as a crucial characteristic for measuring gear machining quality, directly relates to the performance, reliability, and service life of the transmission system. For example, by detecting parameters such as tooth pitch error and tooth profile error, the impact and vibration during gear meshing can be reduced, noise lowered, and transmission smoothness improved. Simultaneously, high-precision gears can reduce uneven contact stress on the tooth surface, delaying wear and fatigue failure, and lowering maintenance costs. Currently, the common method for testing gear machining precision is manual measurement. However, this method is inefficient for testing the precision of multiple gears in the same batch, and errors are easily made when personnel are not focused, making gear precision testing quite inconvenient.

By changing the quality inspection mold, it can be used to test the accuracy of gears of different models and specifications, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gear machining accuracy testing device, comprising a base plate, an air blowing box mounted on the upper side of the base plate, and an air extraction component mounted on the side of the air blowing box.

The mold groups in the two sets of positioning components are spliced ​​together to form a quality inspection mold, and a detachable inspection cover is fitted on the top of the quality inspection mold. Several inspection holes are opened on the side of the inspection cover.

[0005] As a preferred technical solution of this utility model, a first positioning seat is fixed on the side of the positioning plate, and a second positioning seat is fixed on the side of the mold assembly. The second positioning seat is located above the first positioning seat. Positioning holes are provided on the upper side of the first positioning seat and the upper side of the second positioning seat, and positioning pins are slidably disposed in the positioning holes.

[0006] As a preferred embodiment of this utility model, the adjustment assembly includes an adjustment rod rotatably mounted in the mounting frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The gear machining accuracy detection device of this utility model places the gear that needs to be measured in the mounting frame, and then drives the positioning plate to move by adjusting the component, so that the positioning plate drives the mold assembly to move and close the mold. When the mold is closed, the mold assembly clamps the gear. By observing whether the gear and the mold assembly fit tightly or whether the mold assembly can close the mold normally, the gear accuracy is initially detected. It has high detection efficiency and is convenient for sampling and testing multiple gears in the same batch.

[0011] 2. The gear machining accuracy testing device of this utility model includes a testing cover placed above the quality inspection mold. The air extraction component is controlled to extract air from the outside. The airflow entering the blowing box is ejected through the connecting port. The ejected airflow acts on the quality inspection mold. Personnel use an airflow sensor to detect the degree of airflow in the testing hole. When the machined gear meets the standard, the gear should fit snugly against the inside of the quality inspection mold, and the airflow should not be able to flow inside the quality inspection mold. Therefore, the airflow sensor cannot detect the airflow in the testing hole, which facilitates the judgment of whether the gear can fit snugly against the quality inspection mold and realizes the detection of gear machining quality. Multiple testing holes are provided to facilitate the determination of abnormal gear locations.

[0012] 3. The gear machining accuracy testing device of this utility model can be used to replace the mold assembly after the positioning pin is removed from the positioning hole, which facilitates the testing of gears of different models and specifications. The setting of the first positioning seat and the second positioning seat facilitates the connection and positioning of the positioning plate and the mold assembly. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a gear machining accuracy testing device, including a base plate 1, an air blowing box 2 installed on the upper side of the base plate 1, and an air extraction component installed on the side of the air blowing box 2. A mounting frame 3 is fixed above the air blowing box 2. A communication port 4 communicating with the inner cavity of the air blowing box 2 is opened in the middle of the side of the mounting frame 3. Two sets of positioning components are symmetrically arranged in the mounting frame 3. The positioning components include a positioning plate 5 slidably arranged in the mounting frame 3. An adjustment component for adjusting the position of the positioning plate 5 is installed on the side of the mounting frame 3. A mold group 7 is arranged on the side of the positioning plate 5. The mold group 7 and the positioning plate 5 are detachable. The mold group 7 in the two sets of positioning components is spliced ​​to form a quality inspection mold. A detachable inspection cover 10 is fitted on the top of the quality inspection mold. Several inspection holes are opened on the side of the inspection cover 10.

[0017] The gear requiring precision testing is placed within the mounting frame 3. Then, the positioning plate 5 is moved by the adjusting component, causing the positioning plate 5 to move the mold assembly 7 for mold closing. During mold closing, the mold assembly 7 clamps the gear. Preliminary gear precision is assessed by observing whether the gear and mold assembly 7 fit tightly or whether the mold assembly 7 can close properly. This method offers high testing efficiency and facilitates sampling inspection of multiple gears from the same batch. It should be noted that the mold assembly 7 is prepared from a standard gear mold, meeting gear testing standards. For testing different models and specifications of gears, the mold assembly 7 can be replaced to meet the testing requirements of different gear types.

[0018] The inspection cover 10 is set above the quality inspection mold. The air extraction component is controlled to extract air from the outside. The airflow entering the air blowing box 2 is ejected through the connecting port 4. The ejected airflow acts on the quality inspection mold. Personnel use an airflow sensor to detect the degree of airflow in the inspection hole. When the processed gear meets the standard, the gear should fit against the inside of the quality inspection mold. The airflow cannot flow inside the quality inspection mold, so the airflow sensor cannot detect the airflow in the inspection hole. This makes it easy to determine whether the gear can fit against the quality inspection mold and realize the detection of gear processing quality. Multiple inspection holes are set to facilitate the determination of abnormal gear locations.

[0019] A first positioning seat 6 is fixed to the side of the positioning plate 5, and a second positioning seat 8 is fixed to the side of the mold assembly 7. The second positioning seat 8 is located above the first positioning seat 6. Positioning holes are provided on the upper side of the first positioning seat 6 and the upper side of the second positioning seat 8. Positioning pins 9 are slidably arranged in the positioning holes. Preferably, multiple positioning holes are provided, and positioning pins 9 are provided in multiple positioning holes. After the positioning pins 9 are removed from the positioning holes, they can be used to replace the mold assembly 7, which is convenient for testing gears of different models and specifications. The arrangement of the first positioning seat 6 and the second positioning seat 8 facilitates the connection and positioning of the positioning plate 5 and the mold assembly 7.

[0020] The adjustment assembly includes an adjustment rod 11 rotatably mounted inside the mounting frame 3. The two ends of the adjustment rod 11 are provided with threads in opposite directions. Two sets of positioning plates 5 are located at the two ends of the adjustment rod 11 respectively. An operating handle 12 is provided outside the mounting frame 3, and the end of the operating handle 12 is connected and fixed to one end of the adjustment rod 11. By rotating the adjustment rod 11 through the operating handle 12, the adjustment rod 11 can drive the positioning plates 5 to move under the action of the threads, thereby realizing the opening and closing of the mold assembly 7. The opening and closing of the mold assembly 7 facilitates the placement and removal of gears.

[0021] A guide component is provided at a position away from the adjustment component in the mounting frame 3. The guide component includes a guide rod 13 fixed in the mounting frame 3. The positioning plate 5 is slidably connected to the guide rod 13. When the adjustment rod 11 moves the positioning plate 5, the guide rod 13 is located at the other end of the positioning plate 5 and plays a limiting and guiding role in its movement.

[0022] The air extraction assembly includes an air pump group 14 installed on the side of the air blowing box 2, and the air blowing end of the air pump group 14 is connected to the inner cavity of the air blowing box 2. A filter assembly is provided at the air extraction end of the air pump group 14. A switch group or PLC controller for controlling the operation of the air pump group 14 is provided on the outside of the base plate 1. The operation of the air pump group 14 is controlled by the switch group or PLC controller, which facilitates the use of the air pump group 14. When the air pump group 14 is working, it draws air from the outside, and the airflow drawn into the air blowing box 2 is ejected through the communication port 4 on the side of the mounting frame 3 to assist in gear accuracy detection.

[0023] The filter assembly includes a filter box 15 installed on the side of the base plate 1. The air pump unit 14 is fixed to the side of the filter box 15 and communicates with the inner cavity of the filter box 15. The filter box 15 has an installation port on the side away from the air pump unit 14. A filter screen 16 is installed in the installation port. When the air pump unit 14 draws air from the outside, the filter screen 16 on the side of the filter box 15 filters foreign objects such as dust and hair in the airflow to prevent foreign objects from clogging between the gears and the quality inspection mold and affecting the airflow.

[0024] This gear machining accuracy testing device prepares a quality inspection mold based on standard gear data. The quality inspection mold is used to perform batch measurements of gear machining accuracy. The device is also equipped with an air extraction component, which can perform auxiliary measurements based on gas flow during the testing process, facilitating the accuracy testing of gears after machining.
