Description

Technical Field

[0001] The present application relates to the technical field of measuring equipment, and in particular to a measuring device and a measuring equipment having the measuring device. Background Art

[0002] After the product is produced, the product size needs to be measured to determine whether the product is qualified. However, when measuring the product, the existing measuring device needs to manually adjust the measuring end of the measuring device so that the measuring end is aligned with the part to be measured on the product before the product size can be measured. This method requires manual operation to enable the measuring device to measure the product size, which is not easy to realize automation, resulting in low efficiency of the measuring device in measuring the product size. Utility Model Content

[0003] In view of this, the present application provides a measuring device to automatically measure the size of a product and improve the efficiency of measuring the size of the product.

[0004] The present application provides a measuring device, which includes: a mounting mechanism, a first measuring piece, a second measuring piece, a first elastic component, a detector and a movable mechanism; the first measuring piece is movably arranged on the mounting mechanism along a first direction or in the opposite direction of the first direction. The second measuring piece is movably connected to the first measuring piece. The first elastic component elastically acts on the second measuring piece. The movable mechanism is movably arranged on the mounting mechanism, and the movable mechanism moves along a second direction or in the opposite direction of the second direction, and there is an angle between the second direction and the first direction. When the movable mechanism moves along the second direction, the side of the movable mechanism facing the first direction contacts the first measuring piece, and the side of the movable mechanism facing the opposite direction of the first direction contacts the second measuring piece, the movable mechanism applies a first force to the first measuring piece to move along the first direction or to generate a tendency to move along the first direction, and the movable mechanism applies a second force to the second measuring piece to move along the opposite direction of the first direction or to generate a tendency to move along the opposite direction of the first direction. When the movable mechanism moves in the opposite direction of the second direction, the side of the movable mechanism facing the first direction is separated from the first measuring piece, and when the side of the movable mechanism facing the opposite direction of the first direction is separated from the second measuring piece, the movable mechanism cancels the first force and the second force, the first measuring piece moves in the opposite direction of the first direction, and the first elastic component drives the second measuring piece to move along the first direction.

[0005] In the above embodiment, the movable mechanism is moved in the opposite direction of the second direction to cancel the first force applied by the movable mechanism to the first measuring piece, so that the first measuring piece moves in the opposite direction of the first direction under the action of the external force, and the movable mechanism is moved in the opposite direction of the second direction to cancel the second force applied by the movable mechanism to the second measuring piece, so that the second measuring piece moves in the first direction under the action of the first elastic component, so that the first measuring piece and the second measuring piece automatically move away from each other and align with the two ends to be measured of the product respectively. The distance moved by the second measuring piece relative to the first measuring piece is measured by the detector, and the distance between the two ends to be measured of the product can be obtained, so as to achieve the purpose of quickly measuring the size of the product; and then the movable mechanism is moved in the second direction so that the movable mechanism applies the first force to the first measuring piece and the second force to the second measuring piece, so that the first measuring piece and the second measuring piece are reset, so as to facilitate the purpose of the measurement device to measure again.

[0006] In some embodiments, the movable mechanism includes a movable part, and the movable part includes a first part and a second part, the first part is located on one side of the second part along the second direction; the second part has a first working surface and a second working surface, the first working surface is located on one side of the first direction facing the second direction, when the movable mechanism moves along the second direction and the first working surface contacts the first measuring part, the first working surface applies a first force to the first measuring part; the second working surface is located on the side of the first direction facing the second direction, when the movable mechanism moves along the second direction and the second working surface contacts the second measuring part, the second working surface applies a second force to the second measuring part.

[0007] In the above embodiment, by moving the movable part in the opposite direction to the second direction, the first working surface cancels the first force applied to the first measuring part and the second working surface cancels the second force applied to the second measuring part, thereby making the first measuring part and the second measuring part move away from each other, thereby controlling the first measuring part and the second measuring part to be aligned with the two ends to be measured of the product respectively, thereby achieving the purpose of automatically measuring the size of the product.

[0008] In some embodiments, both the first working surface and the second working surface are inclined surfaces, the first working surface extends in the opposite direction of the second direction toward the first direction; the second working surface extends in the opposite direction of the second direction toward the opposite direction of the first direction.

[0009] In the above embodiment, the first working surface and the second working surface are both inclined surfaces, so that when the movable member moves in the opposite direction of the second direction, the first working surface and the second working surface can respectively cancel the forces applied to the first measuring member and the second measuring member.

[0010] In some embodiments, the first measuring member is provided with a first positioning pin, the second measuring member is provided with a second positioning pin, the movable mechanism includes a movable member, the first part and the second part are both located on the movable member, the side of the movable member facing the first direction forms a first working surface, and the side of the movable member facing the opposite direction of the first direction forms a second working surface. When the movable member moves along the second direction and the first working surface contacts the first positioning pin, the movable member applies a first force to the first measuring member through the first positioning pin. When the movable member moves along the second direction and the second working surface contacts the second positioning pin, the movable member applies a second force to the second measuring member through the second positioning pin.

[0011] In the above embodiment, the position of the movable part on the mounting mechanism is adjusted in the opposite direction of the second direction to reduce the supporting effect of the first working surface on the first positioning pin, so that the first measuring part moves in the opposite direction of the first direction under the action of external force; the position of the movable part on the mounting mechanism is adjusted in the opposite direction of the second direction to reduce the pressurizing effect of the second working surface on the second positioning pin, so that the second measuring part can move in the first direction, thereby achieving the effect of separately controlling the movements of the first measuring part and the second measuring part.

[0012] In some embodiments, the first direction is opposite to gravity.

[0013] In the above embodiment, when the movable mechanism cancels the force applied to the first measuring member, the first measuring member automatically moves in the opposite direction of the first direction under the action of gravity.

[0014] In some embodiments, the measuring device further comprises a second elastic component, which acts on the first measuring member or detector to move the first measuring member or detector in a direction opposite to the first direction.

[0015] In the above embodiment, elastic force is applied to the first measuring member or the detector by the second elastic component, thereby reducing the need for other driving mechanisms to drive the first measuring member to move, thereby achieving the purpose of moving the first measuring member in the opposite direction to the first direction.

[0038] The opposite direction of the first direction Z is the gravity direction.

[0039] The embodiment of the present application provides a measuring device 10 for automatically measuring the size of a product 101 to improve the efficiency of measuring the size of the product 101 .

[0040] like Figure 1 and Figure 2 As shown, the measuring device 10 includes a mounting mechanism 12 and a first measuring piece 14, a second measuring piece 15, a first elastic component 16, a detector 11 and a movable mechanism 13, which are movably arranged on the mounting mechanism 12. The first measuring piece 14 is movably connected to the mounting mechanism 12, the first measuring piece 14 and the second measuring piece 15 are movably arranged relative to each other, the first measuring piece 14 and the second measuring piece 15 are respectively fixedly connected to the detector 11, the first elastic component 16 is respectively fixedly connected to the first measuring piece 14 and the second measuring piece 15, the movable mechanism 13 is movably arranged on the mounting mechanism 12, and the movable mechanism 13 is respectively in contact with the first measuring piece 14 and the second measuring piece 15, and applies forces to the first measuring piece 14 and the second measuring piece 15.

[0041] like Figure 2 As shown, the detector 11 includes a movable fixed portion 111 and a detection portion 112. Exemplarily, when the detector 11 is a dial gauge, the fixed portion 111 is the dial gauge body, and the detection portion 112 is the detection end of the dial gauge. The fixed portion 111 of the detector 11 is fixedly connected to the first measuring member 14, and the detection portion 112 of the detector 11 is fixedly connected to the second measuring member 15, so that the first measuring member 14 and the second measuring member 15 can move relative to each other. When it is necessary to measure the product 101, the first measuring piece 14 and the second measuring piece 15 are moved relative to each other, so that the first measuring piece 14 is aligned with one end of the product 101 to be measured, and the second measuring piece 15 is aligned with the other end of the product 101 to be measured, and the second measuring piece 15 drives the detection part 112 to move relative to the fixed part 111, and then the detector 11 measures the distance moved by the detection part 112 relative to the fixed part 111, and the displacement of the second measuring piece 15 relative to the first measuring piece 14 can be obtained, so that by reading the measurement value of the detector 11, the distance between the two ends of the product 101 to be measured can be obtained, so as to realize the function of measuring the size of the product 101.

[0042] like Figure 1As shown, the mounting mechanism 12 is a member with a supporting function such as a mounting frame (not marked) or a mounting block. The mounting mechanism 12 is arranged below the detector 11. The mounting mechanism 12 is provided with a cavity (not marked) running through it along the first direction Z. The cavity is used to accommodate the first measuring piece 14. A part of the first measuring piece 14 extends outside the cavity and is connected to the fixing part 111. When the first measuring piece 14 located in the cavity moves relative to the mounting mechanism 12, it contacts the first measuring piece 14 through the side wall of the cavity, and the side wall of the cavity guides the first measuring piece 14, so that the first measuring piece 14 can stably reciprocate along the first direction Z on the mounting mechanism 12.

[0043] like Figure 2 As shown, the movable mechanism 13 is arranged on the mounting mechanism 12 to reciprocate along the second direction X. There is a certain angle between the second direction X and the first direction Z, or the second direction X is parallel to the third direction Y. The movable mechanism 13 includes a first part 131 and a second part 132, and the first part 131 is located on one side of the second part 132 along the second direction X.

[0044] The second part 132 has a first working surface 1321 and a second working surface 1322. The first working surface 1321 faces the first direction Z, so that when the movable mechanism 13 moves along the second direction X, the first working surface 1321 contacts the first measuring member 14 and applies a first force to the first measuring member 14, so that the first measuring member 14 overcomes the effect of gravity through the first working surface 1321, so as to limit the first measuring member 14 from moving in the opposite direction of the first direction Z. The second working surface 1322 faces the opposite direction of the first direction Z, so that when the movable mechanism 13 moves along the second direction X, the second working surface 1322 contacts the second measuring member 15 and applies a second force to the second measuring member 15, so that the second measuring member 15 overcomes the effect of the first elastic component 16 through the second working surface 1322, so as to limit the second measuring member 15 from moving in the first direction Z. Thereby, the movable mechanism 13 is able to limit the movement of the first measuring piece 14 in the opposite direction of the first direction Z, and to limit the movement of the second measuring piece 15 in the first direction Z, so that by adjusting the position of the movable mechanism 13, the second measuring piece 15 and the first measuring piece 14 can move relative to each other, and then when it is necessary to measure the two ends to be measured of the product 101, the second measuring piece 15 and the first measuring piece 14 can be automatically aligned with the two ends to be measured of the product 101, thereby achieving the purpose of the measuring device 10 automatically measuring the size of the product 101.

[0045] Exemplarily, the movable mechanism 13 is a movable part (not marked) movably arranged outside the mounting mechanism 12, and the first part 131 and the second part 132 are both movable parts. The side of the movable part facing the first direction Z forms a first working surface 1321, and the side of the movable part facing the opposite direction of the first direction Z forms a second working surface 1322.

[0046] like Figure 2 As shown, the first working surface 1321 and the second working surface 1322 are both inclined surfaces. From the first part 131 to the second part 132, the first working surface 1321 gradually extends toward the first direction Z; from the first part 131 to the second part 132, the second working surface 1322 gradually extends in the opposite direction of the first direction Z. When the movable mechanism 13 continues to move along the second direction X, the first working surface 1321 can act on the first measuring member 14 so that the first measuring member 14 gradually moves along the first direction Z to overcome the gravity, and the second working surface 1322 can act on the second measuring member 15 so that the second measuring member 15 gradually moves in the opposite direction of the first direction Z to overcome the action of the first elastic component 16. When the movable mechanism 13 moves in the opposite direction of the second direction X, the first working surface 1321 cancels the force applied to the first measuring piece 14, so that the first measuring piece 14 gradually moves in the opposite direction of the first direction Z, and the second working surface 1322 cancels the force applied to the second measuring piece 15, so that the second measuring piece 15 gradually moves in the first direction Z, thereby achieving the effect of the first measuring piece 14 and the second measuring piece 15 gradually moving away from each other, realizing the automatic alignment of the first measuring piece 14 with one of the ends to be measured of the product 101, and realizing the automatic alignment of the second measuring piece 15 with the other end to be measured of the product 101, so that the detector 11 can quickly measure the distance between the two ends to be measured of the product 101, thereby achieving the purpose of improving the measurement efficiency of the measuring device 10.

[0047] like Figure 2As shown, the first measuring member 14 has a first measuring end 141, and the second measuring member 15 has a second measuring end 151. Both the first measuring end 141 and the second measuring end 151 protrude along a third direction Y, and the third direction Y is a direction perpendicular to the first direction Z. When the inner diameter of the product 101 needs to be measured, the ends of the product 101 to be measured are the two opposite side walls of the inner diameter to be measured. The first measuring end 141 and the second measuring end 151 are designed to protrude along the third direction Y, so that the first measuring end 141 and the second measuring end 151 can be inserted into the inner cavity of the product 101. When the first measuring end 141 and the second measuring end 151 move along the first direction Z and the opposite direction of the first direction Z, the first measuring end 141 and the second measuring end 151 are respectively moved by the relatively moving first measuring piece 14 and the second measuring piece 15, and the first measuring end 141 and the second measuring end 151 can respectively contact with the two ends to be measured of the product 101, so that the movement of the first measuring end 141 and the second measuring end 151 is suppressed by the end to be measured of the product 101, thereby achieving the effect of automatic alignment of the first measuring piece 14 and the second measuring piece 15 with the two ends to be measured of the product 101.

[0048] like Figure 2 As shown, the first measuring member 14 is provided with a first cavity 143 along the first direction Z, so that the detection part 112 and the part of the second measuring member 15 away from the second measuring end 151 are respectively located in the cavity 143, so that when the second measuring member 15 moves relative to the first measuring member 14, the first measuring member 14 protects the second measuring member 15 and the detection part 112 of the detector 11, so as to reduce the risk of the second measuring member 15 and the detection part 112 being easily collided with the outside world, thereby causing damage to the second measuring member 15 and the detection part 112. And by movably setting the second measuring member 15 in the first cavity 143, the first measuring member 14 and the second measuring member 15 can be coaxially arranged in the opposite direction of the first direction Z or the second direction X, reducing the space occupied by the second measuring member 15, making the volume of the measuring device 10 simpler and more compact.

[0049] like Figure 2 and Figure 3 As shown, the first measuring member 14 is provided with a first positioning pin 142 , and the second measuring member 15 is provided with a second positioning pin 152 . A portion of the first positioning pin 142 and a portion of the second positioning pin 152 extend toward the outside of the mounting mechanism 12 , respectively.

[0050] Before measuring the dimensions of the product 101, the movable member is moved along the second direction X so that the first working surface 1321 contacts the first positioning pin 142, and the second working surface 1322 contacts the second positioning pin 152. When the movable member continues to move along the second direction X, the first working surface 1321 applies a first force to the first measuring member 14 through the first positioning pin 142, and the second working surface 1322 applies a second force to the second measuring member 15 through the second positioning pin 152. Therefore, when it is necessary to measure the size of the product 101, the movable part can be moved in the opposite direction of the second direction X to cancel the first force and the second force applied to the first measuring part 14 and the second measuring part 15 respectively. The first measuring part 14 can be gradually moved in the opposite direction of the first direction Z under the action of gravity, and the second measuring part 15 can be gradually moved in the first direction Z under the elastic action of the first elastic component 16, so that the first measuring part 14 and the second measuring part 15 can be automatically aligned with the ends to be measured of different lengths of the product 101, thereby improving the adaptability of the measuring device 10 to automatically measure the ends to be measured of different lengths.

[0051] like Figure 2 As shown, the first elastic component 16 is a first spring, one end of the first elastic component 16 contacts the second measuring member 15, and the other end contacts the first measuring member 14 or the fixing portion 111 of the detector 11. When the second measuring member 15 is moved in the opposite direction of the first direction Z by an external force, the second measuring member 15 compresses the first elastic component 16. When the external force on the second measuring member 15 is cancelled, the second measuring member 15 moves and resets in the first direction Z under the elastic action of the first elastic component 16, so as to achieve the function of driving the second measuring member 15 to move relative to the first measuring member 14.

[0052] Before measuring the size of the product 101, the installation mechanism 12 is moved and the first measuring piece 14 is supported by the movable mechanism 13, so that the installation mechanism 12 drives the first measuring piece 14 to move, thereby driving the first elastic component 16 and the detector 11 to move respectively through the first measuring piece 14, so that the first elastic component 16 drives the second measuring piece 15 to move, so that the first measuring piece 14, the second measuring piece 15 and the detector 11 move synchronously to move away from or close to the product 101, so that the detector 11 displays the reading of the size of the product 101, thereby achieving the purpose of the measuring device 10 measuring the size of the product 101.

[0053] Before measuring the dimensions of the product 101, the movable mechanism 13 on the mounting mechanism 12 is moved along the second direction X, so that the movable mechanism 13 applies a limiting effect to the first measuring member 14, so that the first measuring member 14 overcomes its own gravity and moves along the first direction Z. The movable mechanism 13 applies a limiting effect to the second measuring member 15, so that the second measuring member 15 overcomes the elastic force of the first elastic component 16 and moves in the opposite direction of the first direction Z.

[0054] When measuring the size of the product 101, the first measuring piece 14, the second measuring piece 15, the first elastic component 16, the detector 11 and the movable mechanism 13 are driven by the mounting mechanism 12 to move close to the product 101, so that the detector 11 can measure the size of the product 101. Then the movable mechanism 13 on the mounting mechanism 12 is moved in the opposite direction of the second direction X, so that the movable mechanism 13 cancels the limiting effect on the first measuring piece 14 and the second measuring piece 15 respectively, so that the first measuring piece 14 moves in the opposite direction of the first direction Z under the action of gravity, and the second measuring piece 15 moves in the first direction Z under the resetting action of the first elastic component 16, so as to achieve the effect of relative movement of the first measuring piece 14 and the second measuring piece 15. Since the first measuring piece 14 is fixedly connected to the fixing part 111, and the fixing part 111 is not movably connected to the detector, at this time, the detecting part 112 of the detector 11 will move relative to the fixing part 111 under the drive of the second measuring piece 15, so that the measurement value of the detector 11 changes. Until the first measuring piece 14 and the second measuring piece 15 are respectively aligned with the two ends to be measured of the product 101, the distance between the two ends to be measured of the product 101 is obtained by reading the measurement value of the detector 11, so that the function of the measuring device 10 to automatically detect the size of the product 101 can be realized, which helps to improve the measurement efficiency of the size of the product 101.

[0055] After the measuring device 10 completes the dimensional measurement of the product 101, the movable mechanism 13 is moved along the second direction X so that the movable mechanism 13 re-applies a restrictive effect to the first measuring piece 14 and the second measuring piece 15, thereby moving the first measuring piece 14 and the second measuring piece 15 to reset, so that the measuring device 10 can measure the next product 101.

[0056] like Figure 3 As shown, the measuring device 10 also includes a limit assembly (not marked), which is used to limit the movement of the first measuring member 14 and the second measuring member 15 to reduce the risk of excessive displacement of the first measuring member 14 and the second measuring member 15 and collision with the outside world.

[0057] like Figure 3As shown, the limiting assembly includes a first limiting pin 144 and a second limiting pin 153, wherein the first limiting pin 144 is connected to the first measuring member 14, and the second limiting pin 153 is connected to the second measuring member 15. A first limiting groove 121 and a second limiting groove 122 are provided on the mounting mechanism 12, wherein a portion of the first limiting pin 144 is movably disposed in the first limiting groove 121, and a portion of the second limiting pin 153 is movably disposed in the second limiting groove 122. When the first measuring member 14 and the second measuring member 15 move respectively along the first direction Z or the opposite direction of the first direction Z, the first limiting pin 144 is limited in movement by the first limiting groove 121, so that the moving distance of the first measuring member 14 is suppressed by the first limiting pin 144. The second limiting pin 153 is moved and limited by the second limiting groove 122, so that the moving distance of the second measuring piece 15 can be suppressed by the second limiting pin 153, so as to achieve the purpose of moving and limiting the first measuring piece 14 and the second measuring piece 15, which helps to improve the safety of the measuring device 10.

[0058] In other embodiments, Figure 4 As shown, the measuring device 10 also includes a second elastic component 17, which is a second spring (not marked), one end of which is connected to the first measuring member 14, and the other end of which is connected to the mounting mechanism 12. The second elastic component 17 is used to apply a force in the opposite direction of the first direction Z to the first measuring member 14, so that the first measuring member 14 moves in the opposite direction of the first direction or the first measuring member 14 has a tendency to move in the opposite direction of the first direction. When the opposite direction of the first direction Z is a non-gravity direction, before the size of the product 101 needs to be measured, the movable member is moved along the second direction X, so that the movable member contacts and acts on the first measuring member 14 and the second measuring member 15 respectively, so that the first measuring member 14 overcomes the elastic force of the second elastic component 17 and moves in the first direction Z, and the second measuring member 15 overcomes the elastic force of the first elastic component 16 and moves in the opposite direction of the first direction Z. When it is necessary to measure the size of the product 101, the movable component is moved in the opposite direction of the second direction X, so that the first measuring piece 14 moves in the opposite direction of the first direction Z under the reset action of the second elastic component 17, and the second measuring piece 15 moves in the first direction Z under the reset action of the first elastic component 16, so that the first measuring piece 14 and the second measuring piece 15 move away from each other according to the positions of the two ends to be measured of the product 101 respectively. Similarly, the first measuring piece 14 and the second measuring piece 15 can also be automatically aligned with the two ends to be measured of the product 101, so as to realize the function of the measuring device 10 to automatically measure the size of the product 101.

[0059] Based on the above-mentioned measuring device 10, as Figure 5As shown, the present application also provides a measuring device 100 for measuring the size of a product 101 .

[0060] The measuring device 100 comprises a carrying mechanism 20 and the above-mentioned measuring device 10. The carrying mechanism 20 is used to carry the product 101 and to be installed on the measuring device 10, so that the measuring device 10 can measure the size of the product 101.

[0061] In some embodiments, Figure 5 As shown, a guide structure 21 is provided on the bearing mechanism 20, and the guide structure 21 includes a guide groove 211, and the mounting mechanism 12 is placed on the guide groove 211 for sliding. When the size of the product 101 needs to be measured, the product 101 is placed on the bearing mechanism 20, and then the mounting mechanism 12 is moved relative to the product 101, so that the mounting mechanism 12 drives the first measuring piece 14, the second measuring piece 15, the first elastic component 16, the detector 11 and the movable mechanism 13 to move relative to the product 101, so as to adjust the relative position between the first measuring piece 14 and the product 101, and the relative position between the second measuring piece 15 and the product 101, respectively, so as to facilitate the first measuring piece 14 to drive the first measuring end 141, and the second measuring piece 15 to drive the second measuring end 151 to align with the end to be detected of the product 101, respectively, so as to achieve the purpose of measuring the size of the product 101 by the measuring device 100.

[0062] In some embodiments, the extending direction of the guide groove 211 is perpendicular to the first direction Z.

[0063] In some embodiments, Figure 5 As shown, the measuring device 100 further includes a fixing mechanism 30, which is arranged on the supporting mechanism 20. When measuring the size of the product 101, the fixing mechanism 30 is used to fix the product 101 so that the product 101 and the supporting mechanism 20 are stationary on the mounting mechanism 12, so that the first measuring piece 14 and the second measuring piece 15 are respectively aligned with the ends to be measured of the product 101, so that the measuring device 100 can accurately measure the size of the product 101. At the same time, when it is necessary to measure the size of multiple positions of the same product 101, the product 101 is loosened by the fixing mechanism 30 to adjust the position of the product 101, and then the fixing mechanism 30 is re-fixed on the product 101, so that the measuring device 100 can adapt to the multiple ends to be measured of the product 101 for measurement.

[0064] In some embodiments, the fixing mechanism 30 includes a handle (not marked) and a clamp block (not marked) fixedly connected to the handle. The handle is connected to the supporting mechanism 20, and the handle is adjusted so that the handle drives the clamp block to move, so that the clamp block clamps and fixes the product 101, thereby achieving the purpose of fixing the product 101 by the fixing mechanism 30.

[0065] The working process of the measuring device 10 is as follows:

[0066] Before measuring the size of the product 101, the position of the mounting mechanism 12 is adjusted so that the mounting mechanism 12 drives the first measuring member 14 and the second measuring member 15 to approach the product 101. The movable member is moved in the opposite direction of the second direction X, so that the first working surface 1321 and the second working surface 1322 respectively cancel the first force and the second force applied to the first positioning pin 142 and the second positioning pin 152, so as to release the limiting effect of the movable member on the first positioning pin 142 and the second positioning pin 152, so that the first measuring member 14 drives the first measuring end 141 to gradually move in the opposite direction of the first direction Z under the action of gravity, and the second measuring member 15 drives the second measuring end 151 to gradually move in the first direction Z under the elastic action of the first elastic component 16, until the first measuring end 141 and the second measuring end 151 are respectively aligned with the two ends to be measured of the product 101, and then the detector 11 is read, so that the work of measuring the size of the product 101 by the measuring device 10 can be completed.

[0067] When the next product 101 needs to be measured, the movable member is moved in the opposite direction of the second direction X to move the first measuring member 14 and the second measuring member 15 to reset.

[0068] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
