Description

Technical Field

[0001] This utility model relates to the field of rapid start-up detection technology, and in particular to a pneumatic internal and external M-value detection device. Background Technology

[0002] In the field of gear machining and inspection, the accurate measurement of the M-value (common normal length) is a crucial step in evaluating gear tooth profile accuracy and ensuring assembly fit. The M-value measuring instrument is the core equipment in this process. Currently, there are many mainstream M-value measuring instruments on the market, such as... Figure 1 As shown, the manual adjustment mode has many drawbacks in actual measurement:

[0003] Firstly, the gear operation relies on manual operation. Operators need to visually observe and manually adjust the bolts to ensure that the probe is accurately aligned with the target position of the gear tooth groove or tooth tip. The horizontal alignment operation also relies on manual adjustment. The relative position of the measuring instrument and the gear needs to be repeatedly adjusted to ensure that the measurement reference is aligned, which further prolongs the time of a single measurement, resulting in low measurement efficiency and making it difficult to adapt to the rapid testing needs in mass production scenarios.

[0004] Secondly, the alignment accuracy is easily affected by subjective factors such as personnel experience and visual fatigue, making it difficult to guarantee measurement accuracy. The repeatability of manual adjustment is poor, and the adjustment accuracy varies between different operators or even the same operator at different times, which can easily lead to deviations in measurement data and affect the accurate judgment of gear quality.

[0005] Finally, some measuring instruments have a rather bulky design, making them inconvenient to place and adjust when moving and measuring gears at different workstations in the workshop, which further restricts the flexibility and efficiency of the testing work. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, to provide a pneumatic internal and external M-value detection device that can realize rapid internal and external M-value measurement, has a compact and exquisite structure, and is convenient for quick placement and measurement.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a pneumatic internal and external M-value detection device, including a frame, on which are mounted a...

[0008] The fixed XY fine-tuning platform serves as the reference end for detection and positioning. A fixed-end probe support rod is installed on it to fix and initially position one end of the workpiece being tested. It remains fixed during the measurement process, providing a reliable coordinate origin for the entire measurement.

[0009] The movable XY fine-tuning platform serves as the movable end for detection and positioning. There is a spacing between the fixed XY fine-tuning platform and the movable XY fine-tuning platform. The fixed XY fine-tuning platform and the movable XY fine-tuning platform jointly achieve precise positioning and clamping of the detected part in the horizontal plane (XY plane). A pneumatic cross-roller slide cylinder is installed on the movable XY fine-tuning platform to provide clamping power and high-precision guidance. The extending end of the pneumatic cross-roller slide cylinder is equipped with a movable end probe support rod for fixing and adjusting the other end of the detected part. The movable end probe support rod moves under the drive of the pneumatic cross-roller slide cylinder to complete the clamping and loosening of the detected part. Thus, it not only provides positioning, but more importantly, it is equipped with a pneumatic cross-roller slide cylinder for performing clamping and loosening actions and adapting to detected parts of different sizes.

[0010] The Z-axis fine-tuning platform is used to support and adjust the height of the measurement sensor. It is arranged in a "pin" shape with the fixed XY fine-tuning platform and the movable XY fine-tuning platform, forming a detection area. The detected part is located within this detection area, thus completing the three-sided positioning of the detected part. A measurement sensor is installed on the Z-axis fine-tuning platform. There is a measurement connecting rod between the pneumatic cross-roller slide cylinder and the measurement sensor. The measurement sensor directly determines the M value of the detected part by detecting the displacement of the measurement connecting rod.

[0011] Furthermore, both the fixed XY fine-tuning platform and the movable XY fine-tuning platform include an X-axis fine-tuning component for precisely controlling the displacement of the probe support rod along the X-axis and a Y-axis fine-tuning component for precisely controlling the movement of the X-axis fine-tuning component along the Y-axis. The X-axis fine-tuning component and the Y-axis fine-tuning component are stacked for precisely adjusting the position and posture of the detected part.

[0012] Furthermore, the Z-axis fine-tuning platform includes a Z-axis column. A Z-axis sliding component is installed on the vertical surface of the Z-axis column. The measurement sensor is installed on the slider of the Z-axis sliding component, enabling the measurement sensor to precisely lift and lower to adapt to workpieces of different heights and ensuring that the measurement sensor can be adjusted to the optimal measurement position. An M-value platform is installed on the measurement sensor, and a limit bolt is installed on the M-value platform. The limiting end of the limit bolt faces the detection area.

[0013] Furthermore, the M-value platform is divided into an inner-hole M-value platform and an outer-diameter M-value platform, serving as the installation substrate of the measurement sensor and being quickly replaced according to different measurement requirements (measuring inner holes or outer diameters).

[0014] Furthermore, the inner-hole M-value platform includes an inner-hole platform plate. One end of the inner-hole platform plate is installed on the measurement sensor, and a through-hole is opened at the other end of the inner-hole platform plate. Both the fixed-end probe support rod and the movable-end probe support rod are inserted into the through-hole. The length of the through-hole is greater than the diameter of the detected part, ensuring sufficient space to place the detected part.

[0015] Furthermore, the outer diameter M-value platform includes an outer diameter platform plate. One end of the outer diameter platform plate is mounted on the measuring sensor, and the other end of the outer diameter platform plate has openings on both sides. These two openings are directly opposite the corresponding fixed end probe support rod and movable end probe support rod. The distance between the bottom surfaces of the two openings is less than the diameter of the workpiece being tested, ensuring that there is sufficient space to place the workpiece being tested.

[0016] Furthermore, the fixed XY fine-tuning platform and the movable XY fine-tuning platform are arranged parallel to each other and symmetrically, and their axes are collinear.

[0017] Furthermore, the movable XY fine-tuning platform also includes an installation platform, on which the pneumatic cross roller slide cylinder is mounted. A measuring seat is installed on the installation platform to provide precise guidance and support for the measuring connecting rod, ensuring that it slides only in the specified direction, avoiding skewness and reducing measurement errors. An L-shaped connecting rod is installed on the pneumatic cross roller slide cylinder to convert and transmit the linear motion of the cylinder to the measuring connecting rod.

[0018] The measuring connecting rod is a displacement transmission rod that passes through the measuring base. There is a measuring gap between the end of the measuring connecting rod and the measuring sensor. The other end of the measuring connecting rod is connected to an L-shaped connecting rod. The pneumatic cross roller slide cylinder drives the measuring connecting rod to slide on the measuring base. The measuring connecting rod accurately and without delay transmits the final position of the pneumatic cross roller slide cylinder to the measuring sensor, and is the "bridge" connecting the action end and the sensing end.

[0019] Furthermore, a buffer assembly for limiting and buffering is installed on the pneumatic cross roller slide cylinder. The buffer assembly includes a buffer block and a buffer element. The distance between the buffer block and the buffer element is less than or equal to the distance between the fixed end probe support rod and the movable end probe support rod. When the pneumatic cross roller slide cylinder drives the movable end to move rapidly to the end of the stroke, the buffer block and the buffer element come into contact, and gradually absorb the impact through the damping effect, so that it stops smoothly and protects the equipment.

[0020] Furthermore, the rack is also equipped with a display screen and a human-machine interface, which displays the data collected by the measurement sensors and the calculated M-value results in real time, making it convenient for operators to read the measurement results intuitively.

[0021] The beneficial effects of this utility model are:

[0022] 1. The pneumatic layout replaces the traditional manual adjustment method. The pneumatic drive realizes the automated and precise control of key operations such as probe support rod tooth alignment and horizontal centering. There is no need for repeated manual adjustments, which significantly shortens the preparation time and operation cycle of a single measurement and improves work efficiency.

[0023] 2. The pneumatic drive method has the advantages of stable operation and high repeatability, which can avoid problems such as gear deviation and inaccurate centering caused by subjective factors in manual adjustment. It ensures that the probe is always accurately aligned with the measurement position and the measurement reference remains stably aligned, thus ensuring detection accuracy, improving measurement accuracy, and providing accurate data support for gear quality judgment.

[0024] 3. The equipment's compact and efficient design takes up little space, allowing it to be quickly placed next to the gear to be measured. It adapts to the testing needs of different workstations in the workshop, further improving the continuity and convenience of the testing process and effectively saving time and costs in batch testing scenarios.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0042] like Figures 2-5 The pneumatic internal and external M-value detection device shown includes a frame 4, on which are mounted a...

[0043] The fixed XY fine-tuning platform 1 serves as the reference end for detection and positioning. A fixed end probe support rod 13 is installed on it to fix and initially position one end of the workpiece being tested.

[0044] The movable XY fine-tuning platform 2 serves as the movable end for detection and positioning. There is a gap between the fixed XY fine-tuning platform 1 and the movable XY fine-tuning platform 2. The fixed XY fine-tuning platform 1 and the movable XY fine-tuning platform 2 are arranged parallel to each other and symmetrically. The axes of the fixed XY fine-tuning platform 1 and the movable XY fine-tuning platform 2 are collinear. A pneumatic cross roller slide cylinder 3 is installed on the movable XY fine-tuning platform 2. The extended end of the pneumatic cross roller slide cylinder 3 is equipped with a movable end probe support rod 22, which is used to fix and adjust the other end of the workpiece being tested.

[0045] Among them, such as Figure 3 As shown, both the fixed XY fine-tuning platform 1 and the movable XY fine-tuning platform 2 include an X-axis fine-tuning component 11 for precisely controlling the displacement of the probe support rod along the X-axis and a Y-axis fine-tuning component 12 for precisely controlling the movement of the X-axis fine-tuning component 11 along the Y-axis. The X-axis fine-tuning component 11 and the Y-axis fine-tuning component 12 are stacked together.

[0046] like Figure 3 or Figure 5 As shown, the movable XY fine-tuning platform 2 also includes a mounting platform 23, on which the pneumatic cross roller slide cylinder 3 is mounted. The mounting platform 23 is equipped with a measuring seat 21, and the pneumatic cross roller slide cylinder 3 is equipped with an L-shaped connecting rod 24.

[0047] The measuring connecting rod 10 is inserted through the measuring seat 21. There is a measuring gap between the end head of the measuring connecting rod 10 and the measuring sensor 9. The other end of the measuring connecting rod 10 is connected to the L-shaped connecting rod 24. The pneumatic cross-roller slide cylinder 3 acts to drive the measuring connecting rod 10 to slide on the measuring seat 21.

[0048] The Z-axis fine-tuning platform 5, the fixed XY fine-tuning platform 1, and the movable XY fine-tuning platform 2 are arranged in a "pin" shape among them to form a detection area. The detected part is located within this detection area. The pneumatic cross-roller slide cylinder 3 continuously applies a constant and preset pre-tightening force to make the two probe support rods closely and stably contact the tooth profiles on both sides of the tooth groove, accurately center and fix the workpiece. The limit bolt 8, the fixed-end probe support rod 13, and the movable-end probe support rod 22 form a triangular layout, thus completing the three-way positioning of the detected part.

[0049] Among them, as Figure 4 shown, the Z-axis fine-tuning platform 5 includes a Z-axis column 51. A Z-axis sliding component 52 is installed on the vertical surface of the Z-axis column 51. The measuring sensor 9 is installed on the slider of the Z-axis sliding component 52. An M-value platform is installed on the measuring sensor 9. The M-value platform is divided into an inner-hole M-value platform 6 and an outer-diameter M-value platform 7. A limit bolt 8 is installed on the M-value platform. The limiting end of the limit bolt 8 faces the detection area.

[0050] The measuring sensor 9 is installed on the Z-axis fine-tuning platform 5. The measuring sensor is the core measuring element. There is a measuring connecting rod 10 between the pneumatic cross-roller slide cylinder 3 and the measuring sensor 9. The measuring sensor 9 directly and real-time obtains displacement data by detecting the displacement of the measuring connecting rod 10. This data can be directly used to determine the M value of the detected part after being processed by the system.

[0051] A display screen and a human-machine interaction interface are also installed on the frame 4, which can real-time display information such as the data collected by the measuring sensor and the calculated M-value result, facilitating the operator to directly read the measurement result visually.

[0052] As Figure 5 shown, the inner-hole M-value platform 6 includes an inner-hole platform plate 61. One end of the inner-hole platform plate 61 is installed on the measuring sensor 9. The other end of the inner-hole platform plate 61 is provided with a through-hole 62. Both the fixed-end probe support rod 13 and the movable-end probe support rod 22 are inserted into the through-hole 62. The length of the through-hole 62 is greater than the diameter of the detected part.

[0053] In addition, as Figure 4 shown, a buffer component for limiting and buffering is installed on the pneumatic cross-roller slide cylinder 3. The buffer component includes a buffer block 31 and a buffer member 32. The distance between the buffer block 31 and the buffer member 32 is less than or equal to the distance between the fixed-end probe support rod 13 and the movable-end probe support rod 22.

[0054] Work process:

[0055] Internal gear M-value inspection, the inspected part is an internal gear workpiece:

[0056] Step 1: Using the fixed XY fine-tuning platform 1 as the reference end for detection and positioning, adjust the fixed XY fine-tuning platform 1 and the movable XY fine-tuning platform 2 by using the X-axis fine-tuning component 11 and the Y-axis fine-tuning component 12 to make the axes collinear between them.

[0057] Step 2: Manually rotate the limiting bolt 8 to adjust its length to a suitable length, serving as a preliminary guide and limit when placing the workpiece under test. Install the inner hole M-value platform 6 onto the measuring sensor 9. Place the workpiece under test on the through hole 62 of the inner hole M-value platform 6. At this time, the fixed end probe support rod 13 and the movable end probe support rod 22 are inserted into the through hole 62. Operate the Z-axis fine-tuning platform 5 to adjust the entire measuring system to a suitable height to facilitate the placement of the workpiece under test.

[0058] Step 3: The pneumatic cross roller slide cylinder 3 is started, pushing the movable end probe support rod 24 to move backward, so that the two probe support rods are in close and stable contact with the tooth profile on both sides of the tooth groove. The movement of the pneumatic cross roller slide cylinder 3 pushes the measuring connecting rod 10 to slide in the measuring seat 21 through the L-shaped connecting rod 25. The end displacement of the measuring connecting rod 10 is accurately captured by the measuring sensor 9.

[0059] Step 4: The measuring sensor 9 transmits the displacement signal to the data processing system (such as PLC or dedicated display). The system directly calculates and displays the internal M value of the internal gear according to the preset program and formula. The operator reads the data on the display screen and / or the system automatically determines whether the value is within the qualified range.

[0060] Step 6: After the measurement is completed, the pneumatic valve reverses, the pneumatic cross roller slide cylinder 3 retracts, driving the movable end probe support rod 24 to retract, releasing the tested piece, and the operator can safely remove the tested piece after the measurement is completed, and so on.

[0061] External gear M-value inspection, the inspected part is an external gear workpiece:

[0062] The difference from the M-value detection of internal gears is that: Figures 6-7 As shown, the outer diameter M value platform 7 includes an outer diameter platform plate 71. One end of the outer diameter platform plate 71 is mounted on the measuring sensor 9. Openings 72 are provided on both sides of the other end of the outer diameter platform plate 71. The two openings 72 are directly opposite the corresponding fixed end probe support rod 13 and movable end probe support rod 22. The distance between the bottom surfaces of the two openings 72 is less than the diameter of the object being tested.

[0063] Step 2’ Manually rotate the limiting bolt 8 to adjust its length to a suitable length, serving as a preliminary guide and limit when placing the workpiece under test. Install the outer diameter M-value platform 7 onto the measuring sensor 9, and place the workpiece under test on the outer diameter M-value platform 7. At this time, the fixed end probe support rod 13 and the movable end probe support rod 22 are located in the opening 72. Operate the Z-axis fine-tuning platform 5 to adjust the entire measuring system to a suitable height to facilitate the placement of the workpiece under test. At the same time, manually rotate the limiting bolt 8 to adjust its length to a suitable height.

[0064] Step 3 ’ When the pneumatic cross roller slide cylinder 3 is activated, it pushes the movable end probe support rod 24 forward, so that the two probe support rods are in close and stable contact with the tooth profiles on both sides of the tooth groove. The movement of the pneumatic cross roller slide cylinder 3 pushes the measuring connecting rod 10 to slide in the measuring seat 21 through the L-shaped connecting rod 25. The end displacement of the measuring connecting rod 10 is accurately captured by the measuring sensor 9.

[0065] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
