Description

Technical Field

[0001] The utility model relates to the technical field of M value detection, in particular to an M value detection device for shaft gear parts. Background Art

[0002] During the processing of shaft gear parts, the measurement of various parameters of shaft gear parts is an important process for controlling the quality of parts. In the actual detection process, the radial dimension of gear parts is usually detected by measuring the gear over pin distance, that is, the M value of the gear.

[0003] There are usually two existing methods for measuring the M value of shaft gear parts: The first method is to use a special measuring tool for detection. Generally, it is a special M value measuring tool specially made by professional manufacturers for a certain type of shaft gear parts. It uses a toothless screw rod to control the upper and lower measurement positions and automatically calculates the M value of the measured part by computer. However, the above special measuring tool is only applicable to the large-scale detection of single-type parts, and cannot perform the change-type detection of parts, with low applicability, high manufacturing cost, large occupied space, and requires a computer, so it cannot detect the M value of parts anytime and anywhere; The second method is to directly measure by manually using a gear micrometer. However, during the process of manually holding the gear micrometer for measurement, it is impossible to ensure that the gear micrometer is always in a horizontal state during the measurement process, resulting in large measurement errors and seriously affecting the measurement accuracy of the M value of shaft gear parts. Therefore, it is urgent to develop a new type of M value detection device for shaft gear parts. Summary of the Utility Model

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] See also Figures 1 to 3 The M value detection device for shaft gear parts of the utility model comprises a base 10, a moving component fixed to one side of the base 10, an adjusting component connected to the moving component, and a gear micrometer 50 connected to the adjusting component.

[0027] As an example, the moving assembly is used to control the up and down movement of the gear micrometer 50, so that the measurement personnel can accurately adjust the measurement position of the gear micrometer 50 according to the measurement section of different parts. In this embodiment, the moving assembly includes a fixed frame 21 vertically arranged on the base 10, a screw rod 22 rotatably connected to the top of the fixed frame 21, and a moving block (not shown) screwed to the screw rod 22, and the screw rod 22 is arranged along the height direction of the fixed frame 21. Among them, the screw rod 22 includes a rotating rod portion 221 and a wheel disc portion 222 arranged at one end of the rotating rod portion 221, the other end of the rotating rod portion 221 passes through the top of the fixed frame 21 and extends to the bottom of the fixed frame 21, and the rotating rod portion 221 is screwed to the moving block. Furthermore, in order to improve the convenience for the measurement personnel to rotate the screw rod 22, the screw rod 22 in the utility model also includes a handle portion 223, and the handle portion 223 is fixed to the side of the wheel portion 222 away from the rotating rod portion 221, and the handle portion 223 is arranged along the axial direction of the rotating rod portion 221. In this way, in actual use, the measurement personnel can rotate the screw rod 22 through the handle portion 223, and the moving block will move up or down under the drive of the screw rod 22, thereby driving the gear micrometer 50 to move up and down.

[0028] Furthermore, in order to prevent the measuring position of the gear micrometer 50 from moving during the measurement process, the M value detection device for shaft gear parts of the utility model also includes a locking assembly, which is used to limit the rotation of the screw 22. Specifically, the locking assembly includes an elastic locking block 31 and a locking handle 32 screwed to the elastic locking block 31. The elastic locking block 31 is fixed to the top of the fixing frame 21 by bolts, and the screw 22 is passed through the elastic locking block 31. In this embodiment, the elastic locking block 31 includes a connecting portion 311 and two elastic locking portions provided on the connecting portion 311. The connecting portion 311 is connected to the top of the fixing frame 21 by bolts. An elastic gap 301 is provided between the two elastic locking portions. The two elastic locking portions are symmetrically arranged and enclosed to form a screw through hole for the screw 22 to pass through. The elastic locking portion is also provided with a mounting hole adapted to the locking handle 32, and the mounting hole and the screw through hole are independent of each other.

[0029] Furthermore, the locking handle 32 includes a connecting rod portion 321 and a gripping portion 322 provided at one end of the connecting rod portion 321. The connecting rod portion 321 is adapted to the mounting hole. The gripping portion 322 can be used as a fulcrum for the operator to use the locking handle 32 to improve the ease of use of the locking handle 32. In actual use, the elastic gap 301 is compressed by the threaded connection between the connecting rod portion 321 in the locking handle 32 and the mounting hole, so that the inner wall of the screw through hole gradually fits the circumferential surface of the screw 22, so that the two elastic locking portions lock the screw 22, thereby achieving the purpose of limiting the rotation of the screw 22.

[0030] Furthermore, the two elastic locking parts include a first elastic locking part 312 and a second elastic locking part 313, and the mounting hole includes a mounting through hole and a threaded hole, the mounting through hole is provided on the first elastic locking part 312 or the second elastic locking part 313, and the threaded hole is provided on the second elastic locking part 313 or the first elastic locking part 312. As a specific example, in this embodiment, the first elastic locking part 312 is provided with a mounting through hole for the connecting rod part 321 to pass through, and the second elastic locking part 313 is provided with a threaded hole, which is adapted to the connecting rod part 321. It should be noted that the connection method of the locking handle 32 and the elastic locking block 31 in the utility model is not limited to the structural connection in the above embodiment, and can also be other connection methods that can achieve the purpose of the utility model.

[0031] As an example, the adjusting assembly is used to adjust the horizontal state of the gear micrometer 50 to ensure that the gear micrometer 50 is always in a horizontal state during the measurement process. In this embodiment, the adjusting assembly includes a connecting seat 41, an adjusting member 42 provided on the top of the connecting seat 41, a turntable 43 provided on one side of the connecting seat 41 and linked with the adjusting member 42, and a fixing block 44 fixedly connected to the turntable 43. Among them, the side of the connecting seat 41 facing away from the turntable 43 is fixedly connected to the moving block. In this way, during the rotation of the lead screw 22, the connecting seat 41 can move synchronously with the movement of the moving block. The adjusting member 42 is used to control the rotation angle of the turntable 43, and the end of the fixing block 44 away from the turntable 43 is fixedly connected to the frame of the gear micrometer 50. As a specific example, in this embodiment, the adjusting member 42 includes an adjusting rotating rod 421 and a limit pin 422 for restricting the rotation of the adjusting rotating rod 421. The adjusting rotating rod 421 is linked with the turntable 43 in the way of a worm and worm gear structure. Further, scale parameters are set on the circumference of the turntable 43, and the angle where the turntable 43 is located can be read. During the actual use process, the coordinated operation of the adjusting member 42 and the turntable 43 can adjust the horizontal state of the gear micrometer 60 to ensure the horizontality during the measurement process of the gear micrometer, and further effectively solve the problem that it is not easy to find the center accurately for the parts with even teeth and odd teeth during the tool change.

[0032] Further, to improve the smoothness of the connecting seat 41 moving up and down driven by the moving block, slide rails 23 are respectively fixed on both sides of the fixing frame 21 of the present utility model. The slide rails 23 are arranged along the height direction of the fixing frame 21. At least one slider (not shown in the figure) is respectively provided at both ends of the side of the connecting seat 41 facing away from the turntable 43. The slider is adapted to the slide rail 23. In this embodiment, two sliders are respectively provided at both ends of the side of the connecting seat 41 facing away from the turntable 43, and each slider is slidably connected to the corresponding slide rail 23, thereby realizing the sliding connection between the connecting seat 41 and the fixing frame 21.

[0033] During actual use, the steps for using the M-value detection device for shaft and gear parts of the present utility model can be as follows: Place the part 60 to be measured on the base 10 within the range of the frame of the gear micrometer 50. Then, adjust the position of the gear micrometer 50 according to the position of the cross-section to be measured on the part 60 to be measured. Specifically, first rotate the locking handle 32 to increase the elastic gap 301 between the first elastic locking portion 312 and the second elastic locking portion 313 in the elastic locking block 31. The inner wall of the screw hole formed by the first elastic locking portion 312 and the second elastic locking portion 313 no longer tightly adheres to the circumferential surface of the screw rod 22, achieving the release of the locking state of the elastic locking block 31 on the screw rod 22 and ensuring that the screw rod 22 can rotate under the action of an external force. Subsequently, rotate the screw rod 22 through the handle portion 223 in the screw rod 22, so that the moving block can drive the connecting seat 41 to move up or down, thereby realizing the up and down movement of the gear micrometer 50.

[0034] When the gear micrometer 50 reaches the height of the cross-section to be measured on the part 60 to be measured, rotate the locking handle 32 in the reverse direction. The elastic gap 301 between the first elastic locking portion 312 and the second elastic locking portion 313 is compressed, and the inner wall of the screw hole formed by the first elastic locking portion 312 and the second elastic locking portion 313 will tightly adhere to the circumferential surface of the screw rod 22. Finally, the elastic locking block 31 will lock the screw rod 22 to effectively prevent the screw rod 22 from rotating and ensure that the gear micrometer 50 is fixed at the corresponding height position. Subsequently, check the angle of the turntable 43 in this state. When the reading of the turntable 43 is at the minimum scale, the gear micrometer 50 is in a horizontal state and the M-value can be measured. When the reading of the turntable 43 is not at the minimum scale, the turntable 43 needs to be rotated to make the gear micrometer 50 in a horizontal state. Specifically, loosen the limit pin 422 to release the locking of the limit pin 422 on the adjusting lever 421, and rotate the adjusting lever 421. Since the turntable 43 and the adjusting lever 421 are connected through a worm and worm gear structure, the turntable 43 will also rotate driven by the adjusting lever 421. When the reading of the turntable 43 is at the minimum scale value, at this time, tighten the limit pin 422 so that the limit pin 422 locks the adjusting lever 421 to fix the position of the turntable 43 and ensure that the gear micrometer 50 measures the M-value of the part 60 to be measured in a horizontal state.

[0035] In summary, the beneficial effects of the M-value detection device for shaft and gear parts of the present utility model are as follows: The structure is simple and compact, the manufacturing cost is low, the occupied space is small, and the operation is simple, which can improve the detection efficiency, has high applicability, and can meet the rapid changeover detection of different parts. During actual use, the cooperative operation of the lead screw and the moving block in the moving component can achieve the up and down movement of the gear micrometer, enabling the measurement personnel to accurately adjust the measurement position of the gear micrometer according to the measurement cross-sections of different workpieces, greatly improving the use performance. Further, the cooperative operation of the adjusting member and the turntable in the adjusting component can adjust the horizontality of the gear micrometer, ensuring that the gear micrometer is always in a horizontal state during measurement, reducing measurement errors, and thus improving the measurement accuracy of the M value of shaft and gear parts.
