Description

Technical Field

[0001] The utility model relates to the technical field of shaft processing, in particular to a multi-angle measuring device for a shaft. Background Art

[0002] The measurement in shaft processing is a crucial link in mechanical engineering, which involves the quantitative description and evaluation of the geometric shape, dimensional accuracy and surface quality of the shaft. These measurement data are not only crucial for ensuring the quality of the shaft, but also the basis for subsequent processing and assembly.

[0003] The existing patent discloses a shaft angle measuring device of CN206248016U. A rotating member is connected to a to-be-measured rotating shaft through an anti-rotation matching structure, so that the rotating member can move synchronously with the to-be-measured rotating shaft. The angle of rotation of the rotating member is the angle of rotation of the to-be-measured rotating shaft. The angle of rotation of the rotating member is read through an indicating structure and the angle scale on the graduated disk, which is the angle of rotation of the to-be-measured rotating shaft. No arc operation is required, and the angle measurement of the to-be-measured rotating shaft is more convenient and fast. At the same time, it is also beneficial to reduce the measurement error caused by scribing.

[0004] However, in this patent, only an anti-rotation structure and a rotating member are provided, and only the rotation angle of the to-be-measured rotating shaft is measured. In addition, the height adjustment of the measuring device is not designed in this patent, so that the measuring device cannot adapt to the usage modes in different environments. At the same time, the length and diameter of the to-be-measured shaft cannot be measured. Therefore, the utility model provides a multi-angle measuring device for a shaft. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a multi-angle measuring device for a shaft.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A multi-angle measuring device for a shaft, comprising a fixed seat, a lifting assembly is fixedly connected to the fixed seat. The lifting assembly includes a housing, a lifting spring is arranged inside the housing. The bottom end of the lifting spring penetrates through a first fixing block and is fixedly connected to the bottom end of the lifting assembly. The top end of the lifting spring is fixedly connected to a second fixing block. One end of the second fixing block away from the lifting spring is fixedly connected to a connecting plate, and one end of the connecting plate away from the lifting assembly is rotatably connected to a fixing assembly.

[0007] The fixing component includes a first clamping plate. Third fixing blocks are fixedly connected to both ends of the first clamping plate. A first screw rod is arranged at one end of the connecting plate away from the lifting component. The first screw rod passes through a first nut and the third fixing block, and the first screw rod is rotatably connected to the first nut and the third fixing block. A second clamping plate is rotatably connected to one end of the first screw rod away from the third fixing block. A second slider is fixedly connected to the outer wall of one end of the first clamping plate. An elastic belt is fixedly connected to one end of the first clamping plate away from the second slider. Positioning rods are arranged through both ends of the elastic belt. The second slider is slidably connected to a length measuring component.

[0008] As a preferred embodiment, the length measuring component includes a first scale. First scales are arranged on the first scale. A first sliding groove is formed in the outer wall of one end of the first scale away from the lifting component. A first slider is slidably connected in the first sliding groove. A second sliding groove is formed in one end of the first scale away from the first scale. A second slider is slidably connected to the second sliding groove. A diameter measuring component is fixedly connected to the top end of the length measuring component.

[0009] The beneficial effect of adopting the above further scheme is that the length measuring component that can move enables the device to adapt to the length measurement of rotating shafts of various lengths, greatly increasing the universality of the use of the device. When the bottom or top end of the first slider is at the same horizontal position as the bottom or top end of the measured rotating shaft, the scale on the first scale that is at the same horizontal position as the bottom or top end of the first slider is the length of the measured rotating shaft, preventing visual deviation caused by the line of sight not being at the same horizontal position as the scale line, thereby affecting the accuracy of the data.

[0010] As a preferred embodiment, the diameter measuring component includes a second scale. Second scales are arranged at the upper end of the second scale. A slot hole is formed in one end of the second scale away from the length measuring component. A rotating block is rotatably connected in the slot hole. A third scale is fixedly connected to one end of the rotating block away from the second scale. Second scales are arranged at the top end of the third scale.

[0011] The beneficial effect of adopting the above further scheme is that the size of the rotating shaft with a corner can be flexibly measured, greatly increasing the universality of the use of the device.

[0012] As a preferred embodiment, a second screw rod is arranged through the fixing seat and is fixedly connected to the ground. The top end of the second screw rod is rotatably connected to a second nut.

[0013] The beneficial effect of adopting the above further scheme is that the stability of the device is enhanced, preventing deviation of the measurement data caused by the shaking of the device.

[0014] As a preferred embodiment, the total height of the length measurement component is lower than that of the lifting component, and the length of the diameter measurement component is longer than that of the first screw.

[0015] As a preferred embodiment, the fixing component is symmetrically arranged with respect to the connecting plate as the axis of symmetry, and the positioning rod is inclined.

[0016] The beneficial effect of adopting the above further solution is that the positioning rods on both sides are inclined and do not intersect each other. At the same time, the measured rotating shaft can be clamped to prevent the accuracy of the measurement data from being affected due to the low stability of the rotating shaft.

[0017] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0018] 1. In the present utility model, by providing a lifting component, the staff first lifts the connecting plate, and the connecting plate drives the lifting spring and the fixing component to move synchronously, which is convenient for adjusting the overall height of the measuring device. The height of the measuring device can be adjusted according to different usage requirements. By providing a fixing component, the measured rotating shaft is placed between the elastic belts. The elastic belts are deformed by extrusion so that their surfaces are closely attached to the measured rotating shaft. At the same time, the positioning rods on both sides can also clamp the measured rotating shaft to enhance the stability of the measured rotating shaft.

[0019] 2. In the present utility model, by providing a length measurement component and a diameter measurement component, when measuring the length, the height of the length measurement component is adjusted until the bottom end of the length measurement component contacts the fixed seat. The movable length measurement component can make the device adapt to the length measurement of rotating shafts of various lengths, greatly increasing the universality of the device. At this time, the first slider is moved so that its bottom end or top end is at the same horizontal position as the bottom end or top end of the measured rotating shaft, preventing visual deviation caused by the line of sight not being at the same horizontal position as the scale line, thereby affecting the accuracy of the data.

[0029] The fixing component 3 includes a first clamping plate 31, third fixing blocks 36 are fixedly connected to both ends of the first clamping plate 31, a first screw 37 is arranged at one end of the connecting plate 25 away from the lifting component 2, the first screw 37 penetrates through the first nut 35 and the third fixing block 36, the first screw 37 is rotatably connected to the first nut 35 and the third fixing block 36, a second clamping plate 32 is rotatably connected to one end of the first screw 37 away from the third fixing block 36, a second slider 46 is fixedly connected to the outer wall of one end of the first clamping plate 31, an elastic belt 33 is fixedly connected to one end of the first clamping plate 31 away from the second slider 46, positioning rods 34 penetrate through both ends of the elastic belt 33, and a length measuring component 4 is slidably connected to the second slider 46;

[0030] The fixed component 3 is symmetrically arranged with the connecting plate 25 as the axis of symmetry, and the positioning rod 34 is inclined.

[0031] In this embodiment, the staff adjusts the height of the lifting spring 22 in the lifting component 2 to move the fixed component 3 up and down, so that the device can adapt to different usage requirements. The fixed component 3 plays a fixing role, strengthening the stability of the device and making the measurement data more stable.

[0032] Embodiment 2

[0033] As Figure 1 and Figure 3 shown, the length measurement component 4 includes a first scale 41, on which a first scale 42 is provided. A first sliding groove 43 is formed in the outer wall of one end of the first scale 41 away from the lifting component 2, and a first slider 44 is slidably connected in the first sliding groove 43. A second sliding groove 45 is formed at one end of the first scale 41 away from the first scale 42, and a second slider 46 is slidably connected to the second sliding groove 45. The top of the length measurement component 4 is fixedly connected to a diameter measurement component 5;

[0034] As Figure 1 and Figure 4 shown, the diameter measurement component 5 includes a second scale 51, on the upper end of which a second scale 53 is provided.

[0038] Working principle:

[0039] As Figure 1 andFigure 2 As shown, when in need of use, the staff first lift the connecting plate 25. The connecting plate 25 drives the lifting spring 22 to move synchronously with the fixing assembly 3. When the height of the fixing assembly 3 reaches the height requirement of the measured rotating shaft, stop the operation. Place the measured rotating shaft between the elastic belts 33. The elastic belts 33 are deformed by extrusion so that their surfaces are closely attached to the measured rotating shaft, and the bottom end of the measured rotating shaft contacts the surface of the fixing seat 1. Then, turn the first nuts 35 on both sides of the first clamping plate 31 and the second clamping plate 32 outward. At this time, a gap is formed between the first nuts 35 and the third fixing blocks 36. Stop turning until the gap adapts to the width of the measured rotating shaft.

[0040] As Figure 1 , Figure 3 , and Figure 4 As shown, when measuring the length, adjust the height of the length measuring assembly 4, that is, the second slider 46 slides back and forth in the second chute 45 opened at the corresponding position on the length measuring assembly 4 until the bottom end of the length measuring assembly 4 contacts the fixing seat 1. At this time, move the first slider 44 so that the bottom end or the top end of the first slider 44 and the bottom end or the top end of the measured rotating shaft are at the same horizontal position. At this time, read the scale corresponding to the bottom end or the top end of the first slider 44 on the first scale 42. This scale is the length of the measured rotating shaft. When measuring the width of the rotating shaft, it is determined by reading the distance difference between the two farthest ends of the measured rotating shaft. If there is a rotating part on the measured rotating shaft, the third scale 52 can be rotated downward so that the rotating block 55 rotates in the slot hole 54 opened at the corresponding position of the second scale 51, making a certain angle between the second scale 51 and the third scale 52. Then measure this angle, and this angle is the rotating shaft angle of the measured rotating shaft.

[0041] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
