If the swing amount of the electric screwdriver bit is too large, the screw will be driven in obliquely when rotating the screw, resulting in the housing and the control board not being tightly connected. Therefore, it is necessary to measure the swing amount of the electric screwdriver bit after production. Currently, there is no measuring device for the swing amount, and it is impossible to ensure whether the swing amount of the electric screwdriver bit meets the production requirements, and thus it is impossible to ensure the overall measurement accuracy and measurement efficiency.

[0025] The following will describe in detail the features and exemplary embodiments of various aspects of the present application. To make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the present application in detail with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than limiting the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0026] Such as Figures 1 to 5As shown in the figure, an embodiment of the present application provides a measuring device, which includes: a base 10, including a mounting portion 11 and a measuring member 12, and the measuring member 12 is detachably mounted on the mounting portion 11; a support assembly 20, which is provided on the same side of the base 10 as the mounting portion 11, and the support assembly 20 protrudes from the surface of the base 10; a clamp 30, which is used to clamp the workpiece to be measured 40, including a clamping portion 31 and a connecting portion 32 that are connected to each other. The clamping portion 31 has an annular structure, and the workpiece to be measured 40 is rotatably arranged inside the clamping portion 31. The clamping portion 31 is arranged opposite to the measuring member 12, and the connecting portion 32 is connected to the support assembly 20.

[0027] It should be noted that the measuring member 12 can be any dial indicator, and the workpiece to be measured 40 is a screwdriver bit for fixing bolts. Since the screwdriver bit will rotate during the process of fixing the bolts, rotation will generate a certain amount of swing. If the swing amount does not meet the requirements, the bolt will be driven in obliquely, resulting in an insecure connection of the product.

[0028] Specifically, when implemented, the measuring device of the embodiment of the present application includes a base 10, a support assembly 20, and a clamp 30. The base 10 includes a mounting portion 11 and a measuring member 12, and the measuring member 12 is detachably mounted on the mounting portion 11. The support assembly 20 and the mounting portion 11 are provided on the same side of the base 10 and protrude from this surface of the base 10, so that the clamp 30 connected to the support assembly 20 can have a certain distance from the measuring member 12 mounted on the mounting portion 11. The clamp 30 includes a clamping portion 31 and a connecting portion 32, wherein the connecting portion 32 is connected to the support assembly 20, and the clamping portion 31 has an annular structure, so that the workpiece to be measured 40 can be rotatably arranged inside the clamping portion 31, avoiding the influence of the clamping portion 31 on the workpiece to be measured 40 during rotation. And the clamping portion 31 is arranged opposite to the measuring member 12. When the workpiece to be measured 40 rotates stably inside the clamping portion 31, the measuring member 12 can measure the swing amount generated by the rotation of the workpiece to be measured 40, so as to detect whether the swing amount of the workpiece to be measured 40 meets the requirements, and thus the workpiece to be measured 40 can be adjusted according to the detected swing amount to ensure that the swing amounts of the produced workpieces to be measured 40 all meet the production requirements. Therefore, by using the measuring device of the present application, the swing amount of the workpiece to be measured 40 can be accurately measured when it rotates, and it has high measuring accuracy and measuring efficiency.

[0029] As Figure 1 shown, in the measuring device of the embodiment of the present application, the support assembly 20 includes a support member 21 and a fixing member 22. The support member 21 extends along the first direction X and is perpendicular to the base 10. The fixing member 22 extends along the second direction Y, and the fixing member 22 is slidably connected to the support member 21 along the second direction Y. The connecting portion 32 is connected to the fixing member 22.

[0030] During specific implementation, the support member 21 extends along the first direction X and is disposed perpendicular to the base 10, capable of lifting the fixing member 22 connected thereto to a certain height, so that there is a certain distance between the fixture 30 connected to the fixing member 22 and the base 10. The measured part 40 clamped by the fixture 30 has an installation space and can rotate within this installation space; the fixing member 22 is slidably connected to the support member 21 along the second direction Y, enabling the fixture 30 to slide along the second direction Y following the fixing member 22. When the measured part 40 is not in the measurement position of the measuring member 12, the position of the measured part 40 in the second direction Y can be adjusted, so that the swing amount of the measured part 40 can be accurately measured.

[0031] As Figure 2 shown, in the measuring device according to the embodiment of the present application, the support member 21 includes a plurality of mounting holes 211 penetrating along the second direction Y, and the plurality of mounting holes 211 are arranged at intervals along the first direction X. The fixing member 22 is slidably disposed in one of the mounting holes 211.

[0032] During specific implementation, since the plurality of mounting holes 211 are arranged at intervals along the first direction X, the fixing member 22 can be arbitrarily inserted into one of the mounting holes 211 to adjust the height of the fixing member 22 in the first direction X, so that the measuring device can adapt to measured parts 40 of different lengths, improving the versatility of the measuring device.

[0033] Moreover, the fixing member 22 is slidably disposed in one of the mounting holes 211, enabling the fixing member 22 to slide along the second direction Y, thereby adjusting the position of the measured part 40 in the second direction Y. And the mounting hole 211 is a through hole, and the fixing member 22 can slide out of the mounting hole 211 and be inserted into another mounting hole 211 to complete the height adjustment in the first direction X.

[0034] In the measuring device according to another embodiment of the present application, the support member 21 includes a blocking portion and a mounting chute extending along the first direction X. The mounting chute penetrates the support member 21 along the second direction Y, and the fixing member 22 is slidably disposed in the mounting chute. The blocking portion is detachably disposed in the mounting chute for blocking the fixing member 22 from moving along the first direction X in the mounting chute.

[0035] During specific implementation, the fixing member 22 can move arbitrarily along the first direction X in the mounting chute, thereby realizing free adjustment of the height. And when it moves to a suitable position, the blocking portion can block the fixing member 22, fixing the fixing member 22 at a preset height to ensure that the swing amount of the measured part 40 can be accurately measured.

[0036] As Figure 5As shown in the figure, the measuring device of the embodiment of the present application, wherein the measuring member 12 includes a connected measuring body 121 and a measuring head 122. The measuring body 121 is installed on the installation part 11, the measuring head 122 extends along the second direction Y, and one end of the measuring head 122 away from the measuring body 121 is the measuring end 123; the clamping part 31 is parallel to the base 10, and the clamping part 31 is opposite to the measuring end 123 in position.

[0037] During specific implementation, the clamping part 31 is parallel to the base 10, so that the workpiece 40 to be measured clamped by it can extend along the first direction X and rotate along the direction perpendicular to the first direction X. The measuring head 122 extends along the second direction Y and is perpendicular to the workpiece 40 to be measured. The measuring end 123 provided at the end of the measuring head 122 can abut against the outer peripheral surface of the workpiece 40 to accurately measure the rotation of the workpiece 40 to be measured, so as to accurately measure the swing amount of the workpiece 40 to be measured during the rotation process.

[0038] As Figure 3 As shown in the figure, the measuring device of the embodiment of the present application, wherein the clamping part 31 includes at least a pair of first through holes 311 arranged through, and the two first through holes 311 of each pair are symmetrically arranged about the center of the clamping part 31. The first through holes 311 are used for passing through clamping members, and each pair of clamping members can abut against the opposite sides of the workpiece 40 to be measured and fix the workpiece 40 to be measured.

[0039] During specific implementation, two clamping members can be inserted into the two first through holes 311 and abut against the opposite sides of the workpiece 40 to be measured to clamp the workpiece 40 to be measured, so as to prevent the workpiece 40 to be measured from falling off when clamped in the clamping part 31 and affecting the measurement result.

[0040] Specifically, the clamping member is a bolt, the outer surface of which is an external thread, and the inner surface of the first through hole 311 is provided with an internal thread. The clamping member and the first through hole 311 can be thread-mated so that the clamping member can pass through and be fixed in the first through hole 311 and abut against the opposite sides of the workpiece 40 to be measured. When it is necessary to disassemble the workpiece 40 to be measured, the clamping member can be screwed out of the first through hole 311 to release the fixation of the workpiece 40 to be measured by the clamping members on both sides.

[0041] Optionally, the clamping member can be an elastic columnar structure. When passing through the first through hole 311, it can undergo elastic deformation so that the clamping member can be fixed in the first through hole 311 and abut against the opposite sides of the workpiece 40 to be measured. When it is necessary to disassemble the workpiece 40 to be measured, the clamping member can be directly pulled out of the first through hole 311 to release the fixation of the workpiece 40 to be measured by the clamping members on both sides.

[0042] As Figure 4As shown in the figure, the measuring device according to the embodiment of the present application, wherein the fixing member 22 has a clamping groove 221, the clamping groove 221 is in a square groove structure, and the connecting portion 32 is a columnar structure adapted to the shape of the clamping groove 221, and the connecting portion 32 can be clamped and matched with the clamping groove 221.

[0043] In specific implementation, the square structure of the clamping groove 221 is adapted to the outer shape of the columnar structure of the connecting portion 32, so that the connecting portion 32 can be clamped into the clamping groove 221 for fixation. Moreover, the setting of both of them being square structures facilitates the connecting portion 32 to enter or disengage from the clamping groove 221, which is convenient for the operator to install.

[0044] Optionally, as Figure 4 shown, the connecting portion 32 is composed of two spaced sub-connecting portions 321, the clamping portion 31 is an annular structure with a notch, and the two sub-connecting portions 321 are connected to both ends of the notch of the clamping portion 31. When the operator puts the measured piece 40 into the clamping portion 31, the space inside the clamping portion 31 can be enlarged by expanding the distance between the sub-connecting portions 321, so that the measured piece 40 can smoothly enter the space of the clamping portion 31, and after being put in, the distance between the sub-connecting portions 321 can be restored, so that the clamping portion 31 can clamp the measured piece 40.

[0045] As Figure 1 shown, the measuring device according to the embodiment of the present application, wherein the mounting portion 11 is recessed in the surface of the base 10, and the measuring member 12 is mounted in the mounting portion 11.

[0046] In specific implementation, mounting the measuring member 12 in the recessed mounting portion 11 can prevent the external environment from affecting the measuring member 12 during the measurement process, avoid the appearance of interference factors, and make the measurement of the swing amount more accurate.

[0047] As Figure 3 shown, the measuring device according to the embodiment of the present application, wherein the base 10 further includes a plurality of second through holes 13 penetrating along the first direction X, the second through holes 13 are used for installing connecting members, and the plurality of second through holes 13 are all arranged in the mounting portion 11, and the measuring member 12 and the base 10 are fixedly connected through the connecting members in the second through holes 13. Among them, the connecting member is a bolt.

[0048] In specific implementation, the connecting member can pass through the second through hole 13, thereby fixing the base 10 and the measuring member 12, ensuring the stability of the measuring member 12 during the measurement process, and avoiding the situation that the measuring member 12 is displaced after contacting the rotating measured piece 40, resulting in inaccurate measurement.

[0049] As Figure 3As shown, the measuring device according to the embodiment of the present application, wherein the base 10 further includes an avoidance groove 14 recessed along the first direction X. The avoidance groove 14 and the installation portion 11 are disposed on opposite side surfaces of the base 10. The avoidance groove 14 is disposed opposite to the positions of a plurality of second through holes 13. The avoidance groove 14 is used to accommodate the part of the connecting member protruding from the second through holes 13.

[0050] During specific implementation, when the connecting member fixes the base 10 and the measuring member 12, the bolt head portion of the connecting member will be disposed outside the second through holes 13 and on one side of the bottom surface of the base 10. A recessed avoidance groove 14 is formed on the bottom surface of the base 10 so that the bolt head portion is located in the avoidance groove 14. Such a setting will not cause the bolt head to protrude from the bottom surface of the base 10, thus ensuring that the measuring device can be stably placed on the table without tilting.

[0051] Moreover, the setting of the avoidance groove 14 reduces the overall weight of the measuring device and the overall cost of the measuring device.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "including..." do not exclude the existence of additional identical elements in the process, method, article or device including the said elements.

[0053] The above is only the specific implementation manner of the present application. Those skilled in the art can clearly understand that for the convenience and brevity of description, the specific working processes of the above-described systems, modules and units can refer to the corresponding processes in the foregoing method embodiments and will not be repeated here. It should be understood that the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application.
