Description

Technical Field

[0001] The utility model relates to the technical field of gear detection, in particular to a comprehensive gear detection device. Background Art

[0002] Gears are an important part of mechanical transmission components. Their working accuracy directly affects the operating efficiency and life of the equipment. If the gear accuracy is not high, it will cause problems such as excessive noise, low transmission efficiency, and shortened service life of the machinery and equipment. Therefore, testing the gear accuracy is a necessary means to maintain stable operation of machinery and equipment.

[0003] In traditional gear processing inspection, the detection of tooth surface runout is carried out by inserting the deflection meter through the mandrel. From the beginning of clamping to the completion of the inspection, the deflection meter needs about 100 seconds. During the inspection, the gear is coaxially fixed on the mandrel and positioned by the inner hole. The verticality assurance accuracy of the mandrel is low, which can easily cause the verticality of the workpiece to fail to meet the requirements, and the inspection accuracy is difficult to guarantee. In addition, the height detection generally uses a height gauge and records the data manually. The height detection accuracy is low, making it increasingly difficult for traditional inspection methods to meet the technical requirements of the growing accuracy requirements.

[0029] In order to solve the problems of low detection efficiency and detection accuracy of traditional gear detection, the utility model provides a gear comprehensive detection device, which is used for parameter detection of gears in a gearbox, wherein an industrial computer, a loading plate, a drive motor and a column are arranged in a machine platform, the column is led out from the middle part of the annular loading plate, and a first detection module is also arranged on the machine platform, and a runout measurement head and a top surface measurement head are arranged at one end of the first detection module pointing to the loading plate, the runout measurement head is arranged horizontally, and is arranged in alignment with the side of the gear to be measured placed on the loading plate, and the top surface measurement head is arranged vertically, and is arranged in alignment with the top surface of the gear to be measured placed on the loading plate; a bottom surface measurement head is also arranged on the upper surface of the machine platform, and the bottom surface measurement head is arranged vertically and is placed on the loading plate. The bottom surface of the gear to be measured on the object plate is aligned; an inner hole measuring head is arranged in the column and is aligned with the inner hole of the gear to be measured placed on the object plate; when the first detection module moves to the position of the gear to be measured, under no-load conditions, the measurement value of each measuring head is fixed, and when the gear to be measured is placed on the object plate and rotates with the rotation of the object plate, each measuring head contacts the corresponding measuring point of the gear to be measured, and the measurement value changes. According to the fixed value and change of the measurement value, and the no-load relative position between each measuring head, various parameters of the gear to be measured can be obtained, wherein the tooth surface height parameter can be obtained according to the measurement value of the top surface measuring head and the bottom surface measuring head, and the runout parameter can be obtained according to the measurement value of the runout measuring head and the inner hole measuring head. Among them, the horizontal feature of the object plate is easy to ensure, and thus the posture stability of the gear to be measured placed on the object plate can be ensured, and multiple measuring heads are arranged, and as the object plate rotates, the gear height and tooth surface runout of the gear to be measured can be measured simultaneously, effectively improving the detection accuracy and detection efficiency.

[0030] Specifically, Figures 1 to 3As shown, the gear comprehensive detection device of this embodiment includes a machine platform 10, in which a driving motor, a loading plate 30, a column 11, and an industrial computer are arranged. The loading plate 30 is a circular ring structure so that the column 11 can be led out from it, and the column 11 is fixed to the machine platform 10. The stator of the driving motor is fixedly connected to both the machine platform 10 and the column 11, which can improve the fixing stability of the driving motor. The driving motor and the loading plate 30 can be connected by a flange or the like, and the industrial computer is connected to the driving motor to control the operation of the driving motor, thereby controlling the rotation of the loading plate 30.

[0031] A first detection module 20 and a second detection module 40 are arranged on the upper surface of the machine 10 and are distributed in an L shape on two sides of the carrier plate 30. A runout measurement head 01 and a top surface measurement head 02 are arranged at one end of the first detection module 20 pointing to the carrier plate 30. When the gear to be measured is placed on the carrier plate 30, the runout measurement head 01 and the top surface measurement head 02 can respectively contact the a1 and a2 points of the gear to be measured.

[0032] On the machine platform 10 , a bottom surface measuring head 03 is disposed at the outer periphery of the carrier plate 30 . When the gear to be measured is placed on the carrier plate 30 , the bottom surface measuring head 03 contacts the point a3 of the gear to be measured.

[0033] An inner hole measuring head 04 is disposed in the column 11 . When the gear to be measured is placed on the carrier plate 30 , the inner hole measuring head 04 is aligned with the point a4 of the inner hole of the gear to be measured.

[0034] The first detection module 20 is movably connected to the machine platform 10 through a linear slide rail 201, so that it can be set away from the loading plate 30 before detection, which is convenient for positioning the gear to be tested. After the gear to be tested is placed on the loading plate 30, the first detection module 20 is driven to move along the linear slide rail 201 until the runout measurement head 01 and the top surface measurement head 02 at its end move to the corresponding positions of the gear to be tested.

[0035] In order to facilitate the movement of the first detection module 20, a first handle 202 is further provided. The first handle 202 is an L-shaped structure, which is convenient for holding and operation. The first handle 202 is movably connected to a connecting rod to form a two-connecting rod structure. The first detection module 20 and the machine platform 10 are connected by the two-connecting rod structure, so that the first detection module 20 can be conveniently driven to move along the linear slide rail 201. By manually operating the first handle 202, the detection loading and detection unloading of the first detection module 20 can be quickly realized.

[0036] Considering the actual structure of the gear to be tested, such as Figure 2As shown, the side edge of the top surface is higher than the tooth surface at the top. To facilitate the placement of the top surface measuring head 02, in this embodiment, the first detection module 20 also includes a vertical slide rail, and the top surface measuring head 02 is movably connected to the main body of the first detection module through the vertical slide rail. After the gear to be tested is placed on the carrier plate 30, with the detection loading of the first detection module 20, the runout measuring head 01 can directly contact the gear to be tested smoothly, and the top surface measuring head 02 is positioned at the response position of the gear to be tested with a higher initial position, and then moves vertically downward to the standard height and contacts the top surface tooth surface of the gear to be tested.

[0037] To facilitate the operation of the top surface measuring head 02, in this embodiment, a second handle 203 is also provided on the first detection module 20. The second handle 203 is connected to the top surface measuring head 02 through a rack transmission mechanism, so that the top surface measuring head 02 can be driven to move vertically through the movement of the second handle 203.

[0038] The first handle 202 and the second handle 203 are both provided with limit position limiting structures and snap-on structures, and when they move to the limit position, they can fix themselves, thereby positioning the main body of the first detection module 20 and the top surface measuring head 02 to the preset position.

[0039] In the detection loading state, the runout measuring head 01 and the inner hole measuring head 04 are preferably aligned and matched, and are located in the same radial direction of the gear to be measured. The runout data of the gear to be measured can be obtained through the no-load data and detection data of the two.

[0040] Multiple inner hole measuring heads 04 can be set up, and multiple side wall points of the inner hole of the gear to be measured can be detected at the same time, thereby improving the comprehensive detection accuracy. Multiple inner hole measuring heads 04 can be set at the same height, and can also be set vertically. When set vertically, the positioning posture of the gear to be measured can also be synchronously detected.

[0041] In order to reduce the amount of data processing, the loading plate 30 is placed flat and the upper surface is finely processed to ensure the flatness of the load-bearing surface, which can ensure the test accuracy requirements and further reduce the detection requirements of the positioning posture of the gear to be tested.

[0042] Since the gear to be tested is in a rotating state during detection, the runout measuring head 01, the top surface measuring head 02, the bottom surface measuring head 03 and the inner hole measuring head 04 can be arranged in a group on the same side. A group of data can be obtained when the gear to be tested rotates one circle, and multiple groups of data can be obtained when the gear rotates multiple circles. In an optional embodiment, the runout measuring head 01, the top surface measuring head 02, the bottom surface measuring head 03 and the inner hole measuring head 04 are each arranged in a pair and are symmetrically arranged relative to the central axis of the carrier plate 30. Two groups of data can be obtained simultaneously, thereby reducing hardware errors and improving the credibility of the detection results.

[0043] The end of the second detection module 40 pointing to the carrier plate 30 is provided with a waist end surface measuring head 05 for measuring the tooth surface at point a5 of the gear to be measured. The corresponding tooth surface height parameters can be obtained in combination with the data of the bottom surface measuring head 03.

[0044] To facilitate the inspection and loading of the waist end face measuring head 05, in this embodiment, the second inspection module also includes a slider and rail structure, and the waist end face measuring head 05 is movably connected to the main body of the second inspection module through the slider and rail structure. The slider and rail structure can be manually driven by setting a handle and a gear rack mechanism.

[0045] The industrial computer includes a button-type detection controller 41 and a detection result display. After manually driving the first handle 202 and the second handle 203, and controlling the movement of the slider and rail structure of the second detection module, so that each measuring head is loaded to the corresponding measurement point, the start button on the button-type detection controller 41 is pressed to drive the motor to run, and the loading plate 30 rotates. The industrial computer communicates with each measuring head, collects the measurement data of each measuring head, and combines the preset no-load data to obtain the height and runout data of the gear to be measured. The detection results are displayed on the detection result display for easy recording.

[0046] The button-type detection controller 41 also includes a reset button and an emergency stop button. The reset button is used to clear the detection data to facilitate a new round of detection. The emergency stop button is used to stop the operation of the drive motor in time when a fault occurs during the detection to avoid damage to the measuring head.

[0047] The gear comprehensive detection device of the present invention can detect the height and runout data of the gear at the same time. After actual measurement, after the detection loading is completed, by pressing the start button, the industrial computer can generally output the height and runout data within 20 seconds. The detection loading is performed manually, which is easy to operate and time-consuming. Compared with the traditional time of about 100 seconds, the gear comprehensive detection device of the present invention greatly shortens the total time to complete the detection and improves the detection efficiency.

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0049] The above-mentioned embodiments only express several specific implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
