The following description will be given by taking an example of the application of the workpiece fixing tool to the workpiece detection system.

Fig. 1 is a schematic structural diagram of a workpiece fixing tool according to an embodiment of the present application.

Referring to fig. 1, the workpiece fixing tool 100 may include a fixing bracket 110, a moving connection assembly 120, and a plurality of sets of mounting assemblies 130. Wherein each set of mounting assemblies 130 is connected to the fixing bracket 110 by the moving connecting assembly 120, respectively, and each set of mounting assemblies 130 can be detachably connected to the workpiece to be fixed. The movement linkage assembly 120 is configured to allow the mounting assemblies 130 to move relative to the fixed bracket 110 such that the spacing between the sets of mounting assemblies 130 is adjustable.

The mounting assembly 130 may be used to fix a workpiece, so that the workpiece to be fixed may be fixed on the workpiece fixing tool 100 through the mounting assembly 130. For example, the mounting assembly 130 may be detachably connected to the workpiece by means of clamping, fastening, pinning, or the like, and when the workpiece needs to be detected, the workpiece may be connected to the mounting assembly 130, so that the workpiece may be fixed to the workpiece fixing tool 100 to detect the workpiece. After the inspection of the workpiece is completed, the workpiece may be detached from the mounting assembly 130, so that the worker may remove the workpiece from the workpiece fixing tool 100.

It should be noted that the detachable connection manner between each set of mounting assemblies 130 and the workpiece to be fixed may be the same, or may also be different, and specifically, the detachable connection manner between each set of mounting assemblies 130 and the workpiece to be fixed may be selected and set according to specific scene requirements.

The positions of the installation components 130 can be adjusted by moving the connection component 120, and for workpieces of different sizes and shapes, the positions of the installation components 130 can be adjusted according to the specific positions of the detachable connection parts of the installation components 130 on the workpieces, so that the installation components 130 can be detachably connected with the workpieces, and the workpieces can be fixed on the workpiece fixing tool 100 through the installation components 130.

Moreover, by enabling the workpiece fixing tool 100 to meet fixing requirements of different sizes and shapes, frequent replacement of different workpiece fixing tools in a detection system is omitted in the process of detecting workpieces of different sizes and shapes, investment of manpower and time in the workpiece fixing operation process is reduced, the detection flow can be effectively simplified, and the detection efficiency of the detection system is improved.

With continued reference to fig. 1, the moving link assembly 120 may include a first guide member 121 disposed on the fixed bracket 110 and at least one first link member 122 movably disposed on the first guide member 121. The first guide member 121 is disposed in a first direction (see x direction in fig. 1) of the adjustment surface, that is, the first guide member 121 extends in the first direction. The adjusting surface refers to a mounting arrangement surface of the plurality of sets of mounting assemblies 130, that is, a plane where fixing points of the plurality of sets of mounting assemblies 130 on the moving connecting assembly 120 are located, in other words, the adjusting surface can be understood as a plane where bottom surfaces of the plurality of sets of mounting assemblies 130 are located, and the movable adjustment of the mounting assemblies 130 is mainly embodied as position adjustment along the mounting arrangement surface, so that the purpose of adjusting the distance between different mounting assemblies 130 is achieved.

The mounting assemblies 130 may be connected to the first connecting members 122 in a one-to-one correspondence, so that the first connecting members 122 can drive the corresponding mounting assemblies 130 to move. Specifically, the mounting assembly 130 may be connected to the first guide member 121 through the first connecting member 122, and when the first connecting member 122 moves on the first guide member 121 along the first direction, the mounting assembly 130 may be driven to move along the first direction together, so that the mounting assembly 130 may move on the workpiece fixing tool 100. The mounting assembly 130 can be adjusted according to the matching condition with the workpiece, so that the mounting assembly 130 can be connected with the workpiece, and the workpiece fixing tool 100 can fix the workpiece through the mounting assembly 130.

With continued reference to fig. 1, the first guiding member 121 may be a first guiding rail disposed on the fixing bracket 110 along the first direction of the adjusting surface, the first connecting member 122 may be a first sliding block slidably connected with the first guiding rail, and the mounting assemblies 130 may correspond to the first sliding block one to one. For example, the first rail may be an industrial profile, the first rail may have a sliding groove thereon, the sliding groove may extend along an extending direction of the first rail, and the first slider may slide on the sliding groove, so that the first slider may slide along the first rail through the sliding groove. Thus, when the first slider slides along the first guide rail, the first slider can drive the mounting assembly 130 to move along the first guide rail, and the mounting assembly 130 can move along the first guide member 121.

Wherein, the first sliding block (i.e., the first connecting member 122) may include two sliding angle plates respectively disposed at two opposite sides of the mounting assembly 130, one of the plates of the sliding angle plate may be fixedly connected with the mounting assembly 130, and the other plate may be slidably connected to the first guide rail. For example, the first sliding block may include a first plate and a second plate that are connected to each other and perpendicular to each other, wherein the first plate may be fixedly connected to the mounting assembly 130, and the second plate may be slidably connected to the first guide rail. Thus, when the second plate slides along the first guide rail (i.e., the first guide member 121), the first plate can be driven to move, so that the first plate can drive the mounting assembly 130 to move along the first guide rail (i.e., the first guide member 121).

With continued reference to fig. 1, the movement connection assembly 120 may further include a second guide member 123 disposed along a second direction of the adjustment surface (see the y-direction in the figure) and a second connection member 124 movably disposed on the second guide member 123. The second guide member 123 may be disposed on the fixing bracket 110, and the first guide member 121 may be connected to the second guide member 123 by a second connection member 124. Wherein the first direction and the second direction are arranged non-parallel, for example, the first direction and the second direction may be perpendicular to each other as shown in fig. 1, or, in some examples, the first direction and the second direction may be disposed at an acute angle or an obtuse angle therebetween. The first guiding member 121 is driven by the second connecting member 124 to move along the second direction, so that the mounting assembly 130 on the first guiding member 121 is driven by the first guiding member 121 to move along the second direction, so that the mounting assembly 130 can move along the first direction of the adjusting surface, can move along the second direction of the adjusting surface, and can simultaneously move along the first direction and the second direction. Therefore, the mounting assembly 130 can move freely in the adjusting surface through the first guide member 121 and the second guide member 123, the flexibility of the mounting assembly 130 in the adjusting surface can be effectively improved, the workpiece fixing tool 100 can fix workpieces with any sizes and shapes, and the universality and the flexibility of the workpiece fixing tool 100 are effectively improved.

Here, the second guide member 123 may be a second guide rail disposed on the fixing bracket 110 along the second direction of the adjustment surface, the second connecting member 124 may be a second slider slidably connected with the second guide rail, and the first guide member 121 may be connected to the second guide member 123 by the second slider. For example, the second rail may be the same as the first rail, which is also an industrial profile, and may have a sliding groove thereon, through which the second connecting member 124 may slide on the second rail. So that when the second connecting member 124 slides on the second guide rail, the first guide rail can be driven to move on the second guide rail along the second direction (i.e. y direction in fig. 1), and the mounting assembly 130 can move along the second direction.

The structure of the second connecting member 124 is the same as that of the first connecting member 122, and specifically, the arrangement manner of the second connecting member 124 between the first guiding member 121 and the second guiding member 123 may refer to the arrangement manner of the first connecting member 122 between the mounting assembly 130 and the first guiding member 121, which is not described herein again.

The number of the second guide rails (i.e., the second guide members 123) may be two, or the number of the second guide rails may be more than two. For example, referring to fig. 1, two second guide rails may be disposed on the fixing bracket 110, and the two second guide rails may be respectively located at opposite ends of the fixing bracket 110. Both ends of the first rail may be connected to the two second rails through the second connection members 124, respectively. Can effectively improve stability of being connected and reliability between first guide rail and the second guide rail like this, can effectively avoid first guide rail to take place to empty or skew at the in-process that removes along the second direction, help improving stationarity and reliability that installation component 130 removed on adjusting the face.

The number of the first guiding members 121 may be two or more, and the number of the mounting assemblies 130 may be three or more. Each set of the mounting assemblies 130 may be respectively disposed on one first guide member 121, or two or more mounting assemblies 130 may be disposed on one first guide member 121. For example, referring to fig. 1, the workpiece fixing tool 100 in the embodiment of the present application may include three first guide members 121 and three sets of mounting assemblies 130. The three sets of mounting assemblies 130 may be respectively disposed on the three first guide members 121, so that the three first guide members 121 may respectively adjust the positions of the mounting assemblies 130.

Specifically, the number of the first guide members 121 and the mounting assemblies 130 may be selectively set according to a specific application scenario.

Fig. 2 is a schematic structural diagram of a mounting assembly according to an embodiment of the present disclosure.

Referring to fig. 2, the mounting assembly 130 may include a mounting seat 131 and at least one mounting member 132 configured to correspond to the mounting seat 131, wherein the mounting seat 131 may be movably connected with the first guide member 121, such that the mounting member 132 may be movable on the first guide member 121 through the mounting seat 131.

The mounting end of the mounting member 132 is capable of being removably attached to a workpiece to be secured such that the workpiece may be secured to the mounting member 132 and also removed from the mounting member 132. Wherein the connection end of each mounting member 132 is detachably connectable with the mounting seat 131, so that the mounting seat 131 can be selectively connected with the mounting member 132. For example, according to the structural characteristics of the workpiece to be fixed, the mounting member 132 matched with the workpiece may be selected, so that the workpiece may be connected with the mounting seat 131 through the mounting member 132 and then fixed on the workpiece fixing tool 100 through the mounting seat 131. Therefore, the flexibility of the matching of the mounting assembly 130 and the workpiece can be effectively improved, the mounting assembly 130 can meet the fixing requirements of workpieces with different sizes and shapes, and the universality and the flexibility of the workpiece fixing tool 100 are effectively improved.

Wherein the mounting structure 1323 may be configured to be coupled to a workpiece to be secured, e.g., the mounting structure 1323 may be removably coupled to a workpiece to be secured. Such that the workpiece can be secured to the mounting assembly 130 via the mounting structure 1323 and also be removed from the mounting assembly 130.

The connecting structure 1322 may be threadedly engaged with the mounting base 131, for example, a threaded hole may be provided on the mounting base 131, and an external thread engaged with the threaded hole may be provided on the connecting structure 1322, so that when the connecting structure 1322 rotates in the threaded hole, the mounting post 1321 can be adjusted in mounting height (i.e., height in the z direction in fig. 3) by screwing in or out, so as to change the height of the mounting structure 1323. Therefore, when the height of the workpiece to be fixed needs to be adjusted in the production, detection or assembly process, the connecting structure 1322 can be screwed out or screwed in, so that the mounting height of the mounting post 1321 is changed, and further the height of the mounting structure 1323 is changed accordingly, so that the height of the workpiece is changed along with the mounting post 1321, the workpiece fixing tool 100 can effectively meet the requirements of different heights of the workpiece, and the flexibility of the workpiece fixing tool 100 is effectively improved.

Further, when the surface of the workpiece to be fixed that engages with the mounting post 1321 is non-planar, for example, when the engaging surface of the workpiece is curved, the height of the portion of the workpiece that engages with each mounting assembly 130 varies. At this time, the height of the mounting posts 1321 in each mounting assembly 130 may be individually adjusted so that each mounting post 1321 can be highly matched to the workpiece. Therefore, the whole workpiece is in a reasonable posture, subsequent operation is facilitated, the reasonability of workpiece fixing is improved, and the flexibility and the comprehensive performance of the workpiece fixing tool 100 are further improved.

In the embodiment of the present application, referring to fig. 3 and 4, the shapes of the mounting structures 1323 in at least a portion of the mounting assemblies 130 may be different, and the different shapes of the mounting structures 1323 may at least include a positioning pin (as shown in fig. 3) capable of being inserted into and matched with the hole structure of the workpiece to be fixed, and a clamping support block (as shown in fig. 4) capable of clamping the workpiece to be fixed. For example, a hole structure (e.g., a positioning hole) and a clamping portion may be provided on the workpiece to be fixed, and during the fixing process of the workpiece, the positioning pin may be inserted into the hole structure, and the clamping portion may be clamped in the clamping support block. The positioning pin can provide positioning and supporting functions for the workpiece, so that the workpiece is prevented from deviating in the fixing process, and the positioning accuracy of workpiece fixing is improved.

The number of the mounting structures 1323 in the mounting assembly 130, which are positioning pins, may be one, or may also be two, for example, in the embodiment of the present application, the number of the mounting structures 1323 in the mounting assembly 130, which are positioning pins, may be two. The workpiece is positioned by the two positioning pins, so that the workpiece can be effectively prevented from rotating or deviating, and the reliability of workpiece fixation can be effectively improved.

Thus, the plurality of correction devices 400 are distributed around the workpiece fixing tool 100, and the correction ranges of the correction devices 400 are combined to cover the workpiece fixing area more comprehensively, so that the correction devices 400 can correct the detection device 300 in the whole workpiece fixing area, the detection precision of the detection device 300 in the workpiece fixing area is effectively improved, and the correction precision and the detection precision of the detection and correction system 1 are effectively improved.

Referring to fig. 6, the calibration device 400 may include a support column 410 and at least one calibration reference 420 disposed on the support column 410. The calibration reference 420 may provide a positional reference to the detection apparatus 300 so that the detection apparatus 300 may perform calibration according to the positional relationship between the remaining calibration references 420. The support column 410 may include a first support section 411 coupled to the body 200 at the bottom thereof and a second support section 412 disposed at the top end of the first support section 411. The calibration references 420 may be disposed at the top end of the second support section 412, for example, the calibration references 420 may be disposed at the top end of the second support section 412 by snapping, fastening, bonding, screwing, and the like.

The diameter of the first support section 411 may be larger than that of the second support section 412, which helps to reduce the height of the center of gravity of the support column 410, and may reduce or prevent the center of gravity of the support column 410 from being too high to cause the support column 410 to shake or even topple over. The position of the calibration reference 420 is prevented from being changed due to the shaking or toppling of the support column 410, which is helpful for improving the stability of the position of the calibration reference 420, thereby effectively improving the reference precision of the calibration reference 420 to the detection device 300 and improving the calibration precision of the calibration device 400.

The number of the calibration references 420 may be one, or the number of the calibration references 420 may also be two or more, for example, three calibration references 420 may be disposed on the support column 410. The three calibration references 420 can provide reference for the detection device 300 at the same time, and then the detection device 300 is calibrated by combining the results of the three calibration references 420, so that the calibration accuracy of the calibration device 400 can be effectively improved, and the detection accuracy of the detection device 300 can be improved.

The calibration reference 420 can be a ceramic ball, and the ceramic material has good chemical stability, so that the calibration reference 420 can be effectively prevented from being oxidized and deformed, the structural stability and reliability of the calibration reference 420 can be effectively improved, and the reference precision of the calibration reference 420 to the detection device 300 can be improved.
