[0080] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in detail with reference to specific embodiments and the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0081] The terms used herein are merely for describing specific embodiments and are not intended to limit the present invention. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations and / or components, but do not exclude the presence or addition of one or more other features, steps, operations or components.

[0082] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0083] In the prior art, for some relatively fragile workpieces, when adjusting the installation position of the workpiece, directly moving the workpiece is likely to damage the workpiece, and careful operation is required during the process of adjusting the position of the workpiece, which brings certain difficulties to the adjustment or maintenance work. An embodiment of the present invention provides an adjustment device, which realizes the quick and convenient adjustment of the installation position of the workpiece by adjusting the installation component for fixing the workpiece, and will not damage the workpiece.

[0084] The following combines Figures 1 to 7 Describe the adjustment device 400 of the embodiments of the present invention.

[0085] As Figures 1 to 4As shown in the figure, the adjusting device 400 provided by an embodiment of the present invention includes a mounting assembly 430, a first adjusting mechanism 410, and a second adjusting mechanism 420. The mounting assembly 430 includes a first mounting member 431 and a second mounting member 432 which are spaced apart and are used for mounting a workpiece. The first adjusting mechanism 410 is connected to the first mounting member 431 and is configured to perform a linear motion along a first direction and / or a linear motion along a second direction. The second adjusting mechanism 420 is connected to the second mounting member 432 and is configured to perform a linear motion along the first direction and / or a linear motion along the second direction. Wherein, the first adjusting mechanism 410 and the second adjusting mechanism 420 can move synchronously to drive the first mounting member 431 and the second mounting member 432 to move along the first direction and / or the second direction so as to adjust the position of the workpiece. The first direction is as Figure 3 shown by the D1 direction in Figure 2 the figure, and the second direction is as

[0086] shown by the D2 direction in the figure. Exemplarily, the mounting assembly 430 is used for mounting a workpiece, and the workpiece includes fragile articles such as a grating 800. The mounting of the grating 800 will be described below by taking the application of the grating 800 in a detection device as an example. The grating 800 is a narrow strip-shaped plate body. As Figure 5 、 Figure 6 and Figure 7 shown, the detection device includes a detection component 300, an inlet channel component 100 located on the first side of the detection component 300, and an outlet channel component 200 located on the second side of the detection component 300. The first side and the second side are opposite sides of the detection component 300.

[0087] The detection component 300 includes a support frame 31 and a detection assembly. A detection channel 310 is formed inside the support frame 31, and the detection assembly is mounted on the support frame 31. The detection assembly includes a radiation source 32, a detector 33, and a grating assembly. The radiation source 32 and the detector 33 are arranged opposite to each other. The radiation source 32 can be mounted at the lower left corner position of the support frame 31, and the detector 33 is mounted at the upper right corner position of the support frame 31. The grating assembly includes a plurality of gratings, and the number of gratings is set according to actual requirements. For example, the number of gratings is three, and the three gratings are a first grating 34, a second grating 35, and an adjustable grating 36 respectively.

[0088] The first grating 34 and the second grating 35 are arranged close to the radiation source 32, the first grating 34 and the second grating 35 are spaced apart, the first grating 34 includes a first cross arm 341 and a first vertical arm 342, and the second grating 35 includes a second cross arm 351 and a second vertical arm 352. The adjustable grating 36 is arranged close to the detector 33, and the adjustable grating 36 includes a movable cross arm 361 and a movable vertical arm 362. The first cross arm 341, the second cross arm 351, and the movable cross arm 361 are parallel to each other, and the first vertical arm 342, the second vertical arm 352, and the movable vertical arm 362 are parallel to each other.

[0089] When installing the grating assembly, first install the first grating 34 and the second grating 35 on the fixing frame, complete the alignment and adjustment work of the first grating 34 and the second grating 35 in the laboratory, and then install the fixing frame on the support frame 31. Then install the adjustable grating 36 on the adjusting device 400, install the adjusting device 400 inside the support frame 31, and finely adjust the adjustable grating 36 relative to the first grating 34 and the second grating 35. The adjustment effect of the adjustable grating 36 can only be judged by the scanning imaging result. During the debugging process, the position of the adjustable grating 36 is adjusted multiple times through the first adjusting mechanism 410 and the second adjusting mechanism 420 to make the quality of the scanned image reach the expected effect. The structure of the adjusting device 400 will be described in detail below.

[0090] The installation component 430 includes a first installation part 431 and a second installation part 432. The first installation part 431 and the second installation part 432 are arranged at intervals in the third direction, and the third direction is perpendicular to the first direction and the second direction. The length direction of the grating is consistent with the first direction, the thickness direction of the grating is consistent with the second direction, and the width direction of the grating is consistent with the third direction. The structures of the first installation part 431 and the second installation part 432 are the same.

[0091] For example, the first installation part 431 includes a first fixing plate 4311 and a second fixing plate 4312. The first fixing plate 4311 is provided with a first fixing hole, and the second fixing plate 4312 is provided with a second fixing hole. The first fixing hole is a threaded hole, and the second fixing hole is a through hole. The structure of the second installation part 432 is the same as that of the first installation part 431 and will not be described in detail. Place the grating 800 on the two first fixing plates 4311, then place the two second fixing plates 4312 above the grating 800. Along the width direction of the grating 800, the right side area of the grating 800 is clamped between the first fixing plate 4311 and the second fixing plate 4312, and the left side area of the grating 800 is clamped between the first fixing plate 4311 and the second fixing plate 4312. Screw the screw into the second fixing hole and the first fixing hole, and the first fixing plate 4311 and the second fixing plate 4312 are connected by the screw, so that the grating 800 is fixed between the two first fixing plates 4311 and the two second fixing plates 4312. The number of the first fixing holes and the second fixing holes is set according to actual needs. For example, two first fixing holes are provided on each first fixing plate 4311, and two second fixing holes are provided on each second fixing plate 4312. It can be understood that the area between the first installation part 431 and the second installation part 432 makes the middle area of the grating 800 located outside the installation component 430. Therefore, during the process of the ray passing through the grating 800, the installation component 430 will not interfere with the ray.

[0092] Further, an L-shaped limiting groove is recessed on the first fixing plate 4311, and one groove wall surface of the limiting groove is a limiting surface. An L-shaped limiting portion is formed on the second fixing plate 4312. The grating 800 is placed on the first fixing plate 4311, the bottom surface of the grating 800 is attached to one groove wall surface of the limiting groove, and the two side surfaces of the grating 800 are respectively attached to or close to the limiting surfaces of the two first fixing plates 4311. The limiting portion of the second fixing plate 4312 and the limiting groove of the first fixing plate 4311 form a limiting fit. The grating 800 is fixed between the two first fixing plates 4311 and the two second fixing plates 4312, and the two limiting surfaces can effectively prevent the grating 800 from moving in its width direction, improving the stability of the installation of the grating 800.

[0093] Further, a notch is formed on the second fixing plate 4312, and a through hole is provided at a position on the first fixing plate 4311 opposite to the notch. A first connection hole is provided on the first adjusting mechanism 410, and a fastener passes through the through hole and the first connection hole to realize the connection between the first adjusting mechanism 410 and the first mounting member 431. A second connection hole is provided on the second adjusting mechanism 420, and a fastener passes through the through hole and the second connection hole to realize the connection between the second adjusting structure and the second mounting member 432. The fastener includes a bolt and a nut.

[0094] The first adjusting mechanism 410 can be a synchronous belt drive mechanism, a lead screw nut drive mechanism, an electric push rod, a cylinder or other mechanisms capable of performing linear reciprocating motion. The second adjusting mechanism 420 can be a synchronous belt drive mechanism, a lead screw nut drive mechanism, an electric push rod, a cylinder or other mechanisms capable of performing linear reciprocating motion. The first adjusting mechanism 410 and the second adjusting mechanism 420 can perform linear motion synchronously along the first direction, and the first adjusting mechanism 410 and the second adjusting mechanism 420 can perform linear motion synchronously along the second direction.

[0095] Due to the constraints of the manufacturing process, the size of the grating cannot be made very large. Therefore, the movable cross arm 361 of the adjustable grating 36 is usually composed of multiple spliced gratings, and the movable vertical arm 362 is usually composed of multiple spliced gratings. The adjustment of the installation positions of the multiple gratings of the movable cross arm 361 will be described. A plurality of adjusting devices 400 are sequentially installed on the top wall surface of the support frame 31, and a grating 800 is installed on each adjusting device 400.

[0096] The first adjusting mechanism 410 and the second adjusting mechanism 420 perform linear motion along the first direction, driving the mounting assembly 430 and the grating 800 to perform linear motion along the first direction, and can adjust the position of the grating 800 along the first direction. By adjusting the position of the grating 800 along the first direction, it is ensured that the gap between two adjacent gratings 800 is small enough along the length direction of the movable cross arm 361.

[0097] The first adjustment mechanism 410 and the second adjustment mechanism 420 move linearly along the second direction, driving the mounting assembly 430 and the grating to move linearly along the second direction, and can adjust the position of the grating 800 along the second direction. By adjusting the position of the grating 800 along the second direction, it is ensured that the vertical distance between the movable cross arm 361 and the second cross arm 351 meets the requirements. It can be understood that multiple adjustment devices 400 are sequentially installed on the side wall surface of the support frame 31. By adjusting the position of the grating 800 along the first direction, it is ensured that the gap between two adjacent gratings 800 is small enough along the length direction of the movable vertical arm 362. By adjusting the position of the grating 800 along the second direction, it is ensured that the horizontal distance between the movable vertical arm 362 and the second vertical arm 352 meets the requirements.

[0098] The grating 800 is fixed on the mounting assembly 430. The first mounting member 431 is connected to the first adjustment mechanism 410, and the second mounting member 432 is connected to the second adjustment mechanism 420. The first adjustment mechanism 410 and the second adjustment mechanism 420 move linearly along the first direction and can adjust the gap between two adjacent gratings. The first adjustment mechanism 410 and the second adjustment mechanism 420 move linearly along the second direction and can adjust the vertical distance and the horizontal distance between the adjustable grating 36 and the second grating 35. During the whole adjustment process, there is no need to directly move the grating 800. The movement of the mounting assembly 430 drives the grating 800 to move, which can not only flexibly and conveniently adjust the position of the grating 800, but also effectively protect the grating.

[0099] In the embodiment of the present invention, the workpiece is mounted on the mounting assembly 430.

[0117] like Figures 1 to 4 As shown, in an optional embodiment, the first adjustment mechanism 410 also includes a first guide seat 415, the first guide seat 415 is connected to the second sliding member 4121, the first guide seat 415 includes a first guide block 4151 and a first stop block 4152 arranged opposite to each other, the first guide block 4151 is provided with a first guide hole, and the axial direction of the first guide hole is parallel to the first direction. One end of the first sliding member 4111 is convexly provided with a first abutment portion 41114, and the first abutment portion 41114 is located between the first guide block 4151 and the first stop block 4152. The first driving assembly 414 includes a first adjustment member 4141 and a first elastic member 4142, the first adjustment member 4141 is provided on the first guide block 4151, and abuts against the first abutment portion 41114, the first adjustment member 4141 can move along the axial direction of the first guide hole, and the first elastic member 4142 is sandwiched between the first abutment portion 41114 and the first stop block 4152. When an external force is applied to the first adjusting member 4141 , the first abutting portion 41114 moves toward or away from the first limiting block 4152 , driving the first sliding member 4111 to slide along the first sliding rail 4112 .

[0118] Exemplarily, the first guide seat 415 is approximately U-shaped and is disposed on a side of the second connecting portion 41211 of the second sliding member 4121 away from the first fixing portion 4131. The first guide seat 415 includes a first guide block 4151 and a first limit block 4152 that are spaced apart.

[0119] A first abutting portion 41114 is protrudingly formed on one end face of the first sliding portion 41112 in a direction away from the mounting assembly 430. The first abutting portion 41114 is located in the region between the first guiding block 4151 and the first limiting block 4152. A first guiding hole is provided on the first guiding block 4151, and the first adjusting member 4141 is installed at the first guiding hole. The first adjusting member 4141 includes a micrometer head. Define this micrometer head as the first micrometer head.

[0121] When the knob of the first micrometer head is screwed clockwise, the measuring rod of the first micrometer head moves in the first direction towards the direction close to the first limiting block 4152. The measuring rod exerts a thrust on the first abutting portion 41114 towards the side facing the first limiting block 4152, so that the first sliding portion 41112 slides along the first slide rail 4112. At this time, the first elastic member 4142 is compressed and in an energy storage state.

[0122] When the knob of the first micrometer head is screwed counterclockwise, the measuring rod of the first micrometer head moves in the first direction away from the first limiting block 4152. The first elastic member 4142 releases energy, and the resilience of the first elastic member 4142 exerts a thrust on the first abutting portion 41114 towards the side away from the first limiting block 4152, so that the first sliding portion 41112 slides along the first slide rail 4112.

[0123] The first micrometer head and the first elastic member 4142 respectively abut against the two side surfaces of the first abutting portion 41114. During the process of adjusting the first micrometer head, the acting force of the first elastic member 4142 on the first abutting portion 41114 enables the first micrometer head to always bear a reverse pressure, which can effectively eliminate the thread pair clearance of the first micrometer head and ensure the accuracy of position adjustment.

[0124] The adjustment accuracy of the first micrometer head is high, and the adjustment accuracy of the first micrometer head can reach the micron level. By adjusting the position of the grating in the first direction with the first micrometer head, it can ensure that the gap between two adjacent gratings is small enough.

[0125] By applying a rotational motion to the first differential head, the first sliding member 4111 slides along the first slide rail 4112 towards one end of the first slide rail 4112. In addition, the resilience of the first elastic member 4142 enables the first sliding member 4111 to slide along the first slide rail 4112 towards the other end of the first slide rail 4112. Through the cooperation of the first differential head and the first elastic member 4142, the first sliding member 4111 is driven to slide along the first slide rail 4112. The operator only needs to apply a rotational motion to the first differential head to achieve the sliding of the first sliding member 4111, which is convenient to operate and is conducive to accurately adjusting the position of the workpiece.

[0126] As Figures 1 to 4 shown, in an alternative embodiment, the second adjustment mechanism 420 further includes a second guide base 425. The second guide base 425 is connected to the fourth sliding member 4221. The second guide base 425 includes a relatively arranged third guide block 4251 and a second limiting block 4252.

The third adjusting member 4241 can move along the axial direction of the third guide hole, and the third elastic member 4242 is clamped between the second abutting portion 42114 and the second limiting block 4252. By applying an external force to the third adjusting member 4241, the second abutting portion 42114 moves towards or away from the second limiting block 4252, driving the third sliding member 4211 to slide along the third slide rail 4212.

[0127] Exemplarily, the second guide base 425 is approximately U-shaped, and the second guide base 425 is installed on the side of the fourth connecting portion 42211 of the fourth sliding member 4221 that faces away from the second fixing portion 4231. The second guide base 425 includes a third guide block 4251 and a second limiting block 4252 that are spaced apart.

[0128] A second abutting portion 42114 is formed by protruding from one end face of the third sliding portion 42112 in a direction away from the mounting assembly 430. The second abutting portion 42114 is located in the region between the third guide block 4251 and the second limiting block 4252. A third guide hole is provided on the third guide block 4251, and the third adjusting member 4241 is installed at the third guide hole. The third adjusting member 4241 includes a differential head, and this differential head is defined as the third differential head. The third differential head includes a knob and a measuring rod, and the measuring rod passes through the third guide hole. The third adjusting member 4241 can also be an adjusting screw.

[0129] The third elastic member 4242 can be a columnar spring. The third micrometer abuts against one side of the second abutting portion 42114, and the third elastic member 4242 abuts against the other side of the second abutting portion 42114.

[0130] When the knob of the third micrometer is screwed clockwise, the measuring rod of the third micrometer moves in the first direction towards the direction close to the second limiting block 4252. The measuring rod exerts a thrust force on the second abutting portion 42114 towards the side facing the second limiting block 4252, so that the third sliding portion 42112 slides along the third slide rail 4212. At this time, the third elastic member 4242 is compressed and in an energy storage state.

[0131] When the knob of the third micrometer is screwed counterclockwise, the measuring rod of the third micrometer moves in the first direction away from the second limiting block 4252. The third elastic member 4242 releases energy, and the resilience of the third elastic member 4242 exerts a thrust force on the second abutting portion 42114 towards the side away from the second limiting block 4252, so that the third sliding portion 42112 slides along the third slide rail 4212.

[0132] The third micrometer and the third elastic member 4242 respectively abut against the two sides of the second abutting portion 42114. During the adjustment process of the third micrometer, the acting force of the third elastic member 4242 on the second abutting portion 42114 enables the third micrometer to always bear a reverse pressure, which can effectively eliminate the thread pair clearance of the third micrometer and ensure the accuracy of position adjustment.

[0133] The adjustment accuracy of the third micrometer is high, and the adjustment accuracy of the third micrometer can reach the micron level. By adjusting the position of the grating in the first direction through the third micrometer, it can ensure that the gap between two adjacent gratings is small enough.

[0134] By applying a rotational action to the third micrometer, the third sliding member 4211 slides along the third slide rail 4212 towards one end of the third slide rail 4212. In addition, the resilience of the third elastic member 4242 enables the third sliding member 4211 to slide along the third slide rail 4212 towards the other end of the third slide rail 4212. Through the cooperation of the third micrometer and the third elastic member 4242, the third sliding member 4211 is driven to slide along the third slide rail 4212. The operator only needs to apply a rotational action to the third micrometer to realize the sliding of the second sliding member 4121, which is convenient to operate and is beneficial to realizing the precise adjustment of the workpiece position.

[0135] Specifically, the operator applies rotational movements to the first differential head and the third differential head with both hands respectively. The first sliding member 4111 slides along the first slide rail 4112 under the action of the first differential head and the first elastic member 4142. At the same time, the third sliding member 4211 slides along the third slide rail 4212 under the action of the third differential head and the third elastic member 4242, driving the mounting assembly 430 and the workpiece to move in the first direction. There is no need to set a power source, the structure is simple, and the operation is convenient.

[0171] The rotation adjustment of the workpiece will be described in detail below.

[0172] Loosen the two screws connecting the first fixing plate 4311 and the first sliding member 4111 and the two screws connecting the first fixing plate 4311 and the third sliding member 4211. Keep the second adjustment mechanism 420 stationary, and rotate the first differential head on the first adjustment mechanism 410 in the clockwise direction. The first sliding member 4111 moves along the first slide rail 4112 towards one end of the first slide rail 4112. The first rotating shaft moves along the first direction with the first sliding member 4111, driving the mounting assembly 430 and the grating 800 to rotate around the second axis of the second rotating shaft, realizing the clockwise rotation adjustment of the grating 800. Rotate the first differential head on the first adjustment mechanism 410 in the counterclockwise direction.

By rotating the grating 800, the alignment degree of two adjacent gratings 800 is adjusted to ensure that the end faces of two adjacent gratings 800 are aligned.

[0175] Further, during the translation of the first rotating shaft along with the first sliding member 4111, the distance between the first rotating shaft and the second rotating shaft will change. Both of the two shaft holes connecting the first fixing plate 4311 and the second fixing plate 4312 of the mounting assembly 430 to the first rotating shaft are set as long holes, ensuring that the mounting assembly 430 can rotate at an appropriate angle around the second axis.

[0176] During the translation of the second rotating shaft along with the third sliding member 4211, the distance between the second rotating shaft and the first rotating shaft will change. The two shaft holes connecting the first fixing plate 4311 and the second fixing plate 4312 of the mounting assembly 430 to the second rotating shaft are set as long holes, ensuring that the mounting assembly 430 can rotate at an appropriate angle around the first axis.
