Detailed Implementation

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] It should be noted that during the product manufacturing process, quality inspection of components is usually required to ensure product yield. During quality inspection, the parts to be inspected are typically placed on an inspection fixture, which uses its positioning mechanism to support and position the parts, facilitating stable inspection. However, the positioning mechanisms of inspection fixtures in related technologies often lack flexibility and convenience, making it difficult to support and position parts of different sizes and specifications. This hinders inspection efficiency during batch inspections, thus limiting the improvement of product production efficiency.

[0020] like Figures 1 to 7As shown, a detection fixture 100 is provided according to a first aspect of the present disclosure, comprising: a base assembly 110; a first drive assembly 120 disposed on the base assembly 110; a second drive assembly 130 disposed on the base assembly 110; and a clamping assembly 140 having a plurality of clamping spaces 1401, wherein a first length in a first direction and a second length in a second direction of the clamping spaces 1401 are both adjustable, the first direction and the second direction intersect, and the first drive assembly 120 and the second drive assembly 130 are both connected to the clamping assembly 140; wherein the first drive assembly 120 is used to drive the clamping assembly 140 to simultaneously extend or shorten the first length of the plurality of clamping spaces 1401; and the second drive assembly 130 is used to drive the clamping assembly 140 to simultaneously extend or shorten the second length of the plurality of clamping spaces 1401.

[0021] The testing fixture 100 provided in this embodiment includes a base assembly 110, a first drive assembly 120, a second drive assembly 130, and a clamping assembly 140. Both the first drive assembly 120 and the second drive assembly 130 are mounted on the base assembly 110. In practical applications, the base assembly 110 can provide structural support for other components of the testing fixture 100, thereby improving the structural stability and reliability of the testing fixture 100 and enhancing the operational stability of other components during use. The clamping assembly 140 has clamping spaces 1401. In practical applications, the clamping spaces 1401 can be used to place and hold the tested item 200, thus supporting and fixing the tested item 200, improving the stability of the tested item 200 during the testing process. There are multiple clamping spaces 1401. In practical applications, each clamping space 1401 can correspond one-to-one with a tested item 200, making the clamping assembly 140 suitable for performing multiple tests during use. The support and fixation of part 200 has good adaptability to batch inspection operations; the first length of the clamping space 1401 in the first direction and the second length in the second direction are both adjustable. The first direction and the second direction intersect, that is, the first direction and the second direction are two directions of different dimensions. Thus, the structural parameters of the clamping space 1401 have good adjustment flexibility, which can improve the compatibility of the clamping assembly 140 and facilitate the clamping assembly 140 to support and fix the test parts 200 of different sizes and specifications. It can avoid the inspection fixture 100 from being equipped with a variety of clamping assemblies 140 of different specifications for test parts 200 of different sizes and specifications, reduce the number of components of the inspection fixture 100, and thus reduce the workload of replacing the clamping assembly 140 during the inspection of test parts 200 of different sizes and specifications, which is conducive to improving inspection efficiency.The first driving component 120 and the second driving component 130 are both drivenly connected to the clamping component 140. The first driving component 120 and the second driving component 130 can drive the clamping component 140 to perform different actions. Specifically, the first driving component 120 drives the clamping component 140 to perform a first action or a second action. When the clamping component 140 performs the first action, the first lengths of the multiple clamping spaces 1401 extend synchronously. When the clamping component 140 performs the second action, the first lengths of the multiple clamping spaces 1401 shorten synchronously. The second driving component 130 drives the clamping component 140 to perform a third action or a fourth action. When the clamping assembly 140 performs the third action, the second lengths of the multiple clamping spaces 1401 extend synchronously. When the clamping assembly 140 performs the fourth action, the second lengths of the multiple clamping spaces 1401 shorten synchronously. The first drive assembly 120 and the second drive assembly 130 can operate independently. Therefore, under the drive of the first drive assembly 120 and / or the second drive assembly 130, the structural parameters of the multiple clamping spaces 1401 can change synchronously. The inspection fixture 100 can easily perform synchronous adjustments to the multiple clamping spaces 1401, avoiding individual control of the structural parameters of the multiple clamping spaces 1401, thereby improving the efficiency of batch inspection operations.

[0022] Based on this, the testing fixture 100 provided in this embodiment can be used to support and fix multiple test pieces 200 in practical applications using the clamping assembly 140. The clamping assembly 140 has good structural adjustment flexibility and convenience, and is suitable for supporting and positioning test pieces 200 of different sizes and specifications. Moreover, when performing batch testing of test pieces 200, it helps to improve the execution efficiency of testing operations and provides a guarantee for the production efficiency of products.

[0023] It should be noted that, Figures 1 to 3 The double-headed line segment F1 is used to schematically represent the aforementioned first direction, and the double-headed line segment F2 is used to schematically represent the aforementioned second direction.

[0024] It should be noted that the testing fixture 100 provided in this embodiment can be used, but is not limited to, supporting and fixing components of 3C (Computer / Communication / Consumer Electronics) products in practical applications. The aforementioned components of 3C products include, but are not limited to, the glass cover of the camera lens of a mobile phone product, the glass cover of the display module of a smartwatch, etc.

[0025] Understandably, in practical applications, the testing fixture 100 can also clamp and loosen the tested piece 200 by adjusting the aforementioned first and second lengths.

[0026] It is understood that, based on the aforementioned configuration of the testing fixture 100, the power required to adjust the first length of the multiple clamping spaces 1401 can be provided by the aforementioned first drive component 120, and the power required to adjust the second length of the multiple clamping spaces 1401 can be provided by the aforementioned second drive component 130. Thus, the testing fixture 100 does not need to be equipped with separate drive components for the multiple clamping spaces 1401, which can reduce the number of drive components used in the testing fixture 100, reduce the structural complexity of the testing fixture 100, and help reduce the control difficulty of the testing fixture 100 during use, thereby improving the control efficiency of the testing fixture 100.

[0027] It is understood that the aforementioned first direction and the aforementioned second direction can be two mutually perpendicular directions. Based on this, a large dimensional difference can be formed between the first direction and the second direction, which facilitates the clamping component 140 to apply constraint force to the tested object 200 from multiple different orientations, thereby improving the support and positioning effect of the clamping component 140 on the tested object 200.

[0028] It is understood that the boundary of the aforementioned clamping space 1401 can be defined by the inner wall of the clamping component 140. For example, the inner walls of the clamping component 140 used to define the two sides of the clamping space 1401 in the first direction are respectively the first limiting wall and the second limiting wall, and the inner walls of the clamping component 140 used to define the two sides of the clamping space 1401 in the second direction are respectively the third limiting wall and the fourth limiting wall. Combined with the aforementioned configuration of the detection fixture 100, the distance between the aforementioned first limiting wall and the second limiting wall in the first direction is adjustable, and the distance between the aforementioned third limiting wall and the fourth limiting wall in the second direction is adjustable. In practical applications, the first limiting wall, the second limiting wall, the third limiting wall and the fourth limiting wall can all contact and cooperate with the tested part 200, so that the clamping component 140 can limit and constrain the tested part 200 from at least four directions. This can improve the positioning accuracy of the tested part 200 during the detection process while ensuring the support and fixation effect of the tested part 200, thereby improving the detection accuracy and precision.

[0029] like Figure 2As shown, in some examples, the clamping assembly 140 includes a plurality of limiting portions 141, each limiting portion 141 including a first limiting member 141a, a second limiting member 141b, a third limiting member 141c, and a fourth limiting member 141d. The first limiting member 141a and the second limiting member 141b are arranged opposite to each other along a first direction, and the third limiting member 141c and the fourth limiting member 141d are arranged opposite to each other along a second direction. The clamping space 1401 is formed by d; wherein, a plurality of first limiting members 141a and a plurality of second limiting members 141b are connected to the first driving assembly 120, and a plurality of third limiting members 141c and a plurality of fourth limiting members 141d are connected to the second driving assembly 130. The first driving assembly 120 is used to drive the first limiting members 141a and the second limiting members 141b to move toward each other or away from each other, and the second driving assembly 130 is used to drive the third limiting members 141c and the fourth limiting members 141d to move toward each other or away from each other.

[0030] In this technical solution, the clamping assembly 140 may include the aforementioned limiting portion 141. The clamping assembly 140 can support and fix the tested item 200 using the limiting portion 141. The limiting portion 141 includes a first limiting member 141a and a second limiting member 141b arranged opposite to each other along the aforementioned first direction, and a third limiting member 141c and a fourth limiting member 141d arranged opposite to each other along the aforementioned second direction. The first limiting member 141a, the second limiting member 141b, the third limiting member 141c, and the fourth limiting member 141d define the aforementioned clamping space 1401. When clamping the tested item 200, each of the aforementioned limiting members of the limiting portion 141 can be used to clamp the tested item 200. The different parts of the clamping assembly 140 contact and cooperate to constrain the position of the workpiece 200. Based on this, the clamping assembly 140 can limit the workpiece 200 from at least four directions, which can improve the positioning accuracy of the workpiece 200 during the detection process while ensuring the support and fixation effect of the workpiece 200, thereby improving the detection accuracy and precision. The first driving assembly 120 can drive the first limiting member 141a and the second limiting member 141b to move towards each other or away from each other in the first direction, so that the first limiting member 141a and the second limiting member 141b move closer to each other or further away in the first direction. To achieve the aforementioned adjustment of the first length, the second drive assembly 130 can drive the third limiting member 141c and the fourth limiting member 141d to move towards or away from each other in the second direction, thereby achieving the aforementioned adjustment of the second length. This facilitates the clamping assembly 140 in supporting and fixing test pieces 200 of different sizes and specifications. Since there are multiple limiting parts 141, the testing fixture 100 can correspondingly have multiple clamping spaces 1401, and the first limiting member 141 of the multiple limiting parts 141... Both 1a and the second limiting member 141b are connected to the first driving assembly 120, and the third limiting member 141c and the fourth limiting member 141d of the multiple limiting parts 141 are connected to the second driving assembly 130. Thus, the first driving assembly 120 can drive multiple sets of relatively arranged first limiting members 141a and second limiting members 141b to move synchronously, and the second driving assembly 130 can drive multiple sets of relatively arranged third limiting members 141c and fourth limiting members 141d to move synchronously. This enables the synchronous adjustment of the structural parameters of multiple clamping spaces 1401, which is beneficial to improving the execution efficiency of quality inspection operations.

[0031] It is understood that the direction of movement of the first limiting member 141a and the second limiting member 141b moving towards or away from each other is parallel to the aforementioned first direction; the direction of movement of the third limiting member 141c and the fourth limiting member 141d moving towards or away from each other is parallel to the aforementioned second direction.

[0032] It is understood that the aforementioned first limiting member 141a, second limiting member 141b, third limiting member 141c and fourth limiting member 141d may each have the aforementioned first limiting wall, second limiting wall, third limiting wall and fourth limiting wall respectively. The first limiting wall may be formed on the side of the first limiting member 141a facing the second limiting member 141b, the second limiting wall may be formed on the side of the second limiting member 141b facing the first limiting member 141a, the third limiting wall may be formed on the side of the third limiting member 141c facing the fourth limiting member 141d, and the fourth limiting wall may be formed on the side of the fourth limiting member 141d facing the third limiting member 141c.

[0033] For example, the aforementioned first limiting wall, second limiting wall, third limiting wall and fourth limiting wall can all be stepped, which facilitates the mounting of the tested part 200 on the first limiting wall, second limiting wall, third limiting wall and fourth limiting wall, which helps to improve the clamping stability and reliability of the clamping assembly 140 on the tested part 200, and enhances the support and fixing effect of the clamping assembly 140 on the tested part 200.

[0034] like Figure 2 and Figure 3 As shown, in some examples, the clamping assembly 140 further includes: a first sliding portion 142 and a second sliding portion 143, both disposed on the base assembly 110, the first sliding portion 142 and the second sliding portion 143 being adapted to slide relative to the base assembly 110 along a first direction, the first sliding portion 142 and the second sliding portion 143 being spaced apart along the first direction; a third sliding portion 144 and a fourth sliding portion 145, both disposed on the base assembly 110, the third sliding portion 144 and the fourth sliding portion 145 being adapted to slide relative to the base assembly 110 along a second direction, the third sliding portion... 144 and the fourth sliding part 145 are arranged at intervals along the second direction; wherein, the first limiting member 141a and the second limiting member 141b are respectively disposed on the first sliding part 142 and the second sliding part 143, the third limiting member 141c and the fourth limiting member 141d are respectively disposed on the third sliding part 144 and the fourth sliding part 145, the first driving assembly 120 is used to drive the first sliding part 142 and the second sliding part 143 to slide towards each other or towards each other, and the second driving assembly 130 is used to drive the third sliding part 144 and the fourth sliding part 145 to slide towards each other or towards each other.

[0035] In this technical solution, the clamping assembly 140 may further include the aforementioned first sliding portion 142, second sliding portion 143, third sliding portion 144, and fourth sliding portion 145. Based on the aforementioned configuration, the first sliding portion 142 is tractively connected between the first driving assembly 120 and multiple first limiting members 141a; the second sliding portion 143 is tractively connected between the first driving assembly 120 and multiple second limiting members 141b; the third sliding portion 144 is tractively connected between the second driving assembly 130 and multiple third limiting members 141c; and the fourth sliding portion 145 is tractively connected between the second driving assembly 130 and multiple fourth limiting members 141d. Thus, the first driving assembly 120 can drive the first sliding portion 142 and the second sliding portion 143 to slide towards or away from each other along a first direction on the base assembly 110, thereby causing multiple sets of relatively arranged first limiting members 141a and second limiting members 141b to move synchronously towards or away from each other. The second drive assembly 130 can drive the third sliding part 144 and the fourth sliding part 145 to slide towards each other or away from each other on the base assembly 110 along the second direction, thereby driving multiple sets of relatively arranged third limiting members 141c and fourth limiting members 141d to move synchronously towards each other or away from each other. This enables the synchronous adjustment of the aforementioned first length and / or the aforementioned second length of multiple clamping spaces 1401, which is beneficial to improving the execution efficiency of quality inspection operations. Moreover, each sliding part slides in cooperation with the base assembly 110. Accordingly, the base assembly 110 can provide structural support and motion constraints for each sliding part, which is beneficial to improving the motion stability and reliability of the clamping assembly 140 when performing actions, and provides a guarantee for the stable and accurate adjustment of the structural parameters of the clamping space 1401.

[0036] For example, the first sliding part 142 includes a first guide rail 142a, a first guide block 142b, a first mounting member 142c, and a first connecting member 142d; wherein, the slide rail of the first guide rail 142a is fixedly mounted on the base assembly 110 and extends along a first direction, the first connecting member 142d is fixedly mounted on the slider of the first guide rail 142a, so that the first connecting member 142d can slide along the slide rail of the first guide rail 142a, the first mounting member 142c is fixedly mounted on the first connecting member 142d, and the aforementioned plurality of first limiting members 141a are spaced apart on the first mounting member 142c. The guide block 142b is fixedly connected between the first drive assembly 120 and the first mounting member 142c, so that the first guide block 142b can transmit the power provided by the first drive assembly 120 to the first mounting member 142c. Correspondingly, the first drive assembly 120 can drive the first mounting member 142c to slide along the first direction through the first guide block 142b, and cause the multiple first limiting members 141a to displace along the first direction. Under the guidance of the aforementioned first guide rail 142a, the first mounting member 142c can have good motion stability, thereby ensuring the displacement accuracy of the first limiting members 141a.

[0037] Correspondingly, the structure of the second sliding part 143 can be the same as that of the first sliding part 142, that is, the second sliding part 143 may include a second guide rail, a second guide block, a second mounting member and a second connecting member; wherein, the slide rail of the second guide rail is fixedly disposed on the base assembly 110 and extends along the first direction, the second connecting member is fixedly disposed on the slider of the second guide rail, the second mounting member is fixedly disposed on the second connecting member, the aforementioned plurality of second limiting members 141b are spaced apart on the second mounting member, and the second guide block is fixedly connected between the first drive assembly 120 and the second mounting member.

[0038] For example, considering the compact structure of the clamping assembly 140, the first guide rail 142a and the second guide rail can be an integral structure.

[0039] For example, the number of the first guide rail 142a, the second guide rail, the first connector 142d, and the second connector can all be two. The first guide rail 142a and the first connector 142d correspond one-to-one, and the second guide rail and the second connector correspond one-to-one. The two first guide rails 142a are arranged in parallel, and the two first connectors 142d are both connected to the first mounting member 142c. The first guide block 142b can be arranged between the two first connectors 142d, which helps to further improve the movement stability of the first sliding part 142. The two second guide rails are arranged in parallel, and the two second connectors are both connected to the second mounting member. The second guide block can be arranged between the two second connectors, which helps to further improve the movement stability of the second sliding part 143.

[0040] For example, the third sliding part 144 includes a third guide rail 144a, a third guide block 144b, and a third mounting member 144c; wherein, the slider of the third guide rail 144a is fixedly mounted on the base assembly 110, the slide rail of the third guide rail 144a is fixedly connected to the third mounting member 144c and extends along the second direction, so that the third mounting member 144c can slide along the slide rail of the third guide rail 144a, a plurality of the aforementioned third limiting members 141c are spaced apart on the third mounting member 144c, and the third guide block 144b is fixedly connected to the second drive assembly. Between 130 and the third mounting member 144c, the third guide block 144b can transmit the power provided by the second drive assembly 130 to the third mounting member 144c. Correspondingly, the second drive assembly 130 can drive the third mounting member 144c to slide along the second direction through the third guide block 144b, and cause multiple third limiting members 141c to generate displacement along the second direction. Under the guidance of the aforementioned third guide rail 144a, the third mounting member 144c can have good motion stability, thereby ensuring the displacement accuracy of the third limiting members 141c.

[0041] Correspondingly, the structure of the fourth sliding part 145 can be the same as that of the third sliding part 144, that is, the fourth sliding part 145 may include a fourth guide rail, a fourth guide block and a fourth mounting member; wherein, the slider of the fourth guide rail is fixedly disposed on the base assembly 110, the slide rail of the fourth guide rail is fixedly connected to the fourth mounting member and extends along the second direction, a plurality of the aforementioned fourth limiting members 141d are spaced apart on the fourth mounting member, and the fourth guide block is fixedly connected between the second drive assembly 130 and the fourth mounting member.

[0042] It should be noted that, for ease of illustration, the following is used... Figure 3 Parts of the clamping assembly 140 in the left-hand area are hidden.

[0043] like Figures 2 to 5 As shown, in some examples, the first drive assembly 120 includes a first drive section 121 and a first cam mechanism 122. The first drive section 121 is disposed on the base assembly 110, and the first cam mechanism 122 is connected to the first drive section 121. The first drive section 121 drives the first sliding section 142 and the second sliding section 143 to slide towards each other or away from each other through the first cam mechanism 122. The second drive assembly 130 includes a second drive section 131 and a second cam mechanism 132. The second drive section 131 is disposed on the base assembly 110, and the second cam mechanism 132 is connected to the second drive section 131. The second drive section 131 drives the third sliding section 144 and the fourth sliding section 145 to slide towards each other or away from each other through the second cam mechanism 132.

[0044] In this technical solution, the first drive assembly 120 may include the aforementioned first drive section 121 and the aforementioned first cam mechanism 122, and the second drive assembly 130 may include the aforementioned second drive section 131 and the aforementioned second cam mechanism 132. Based on the aforementioned configuration, the first drive assembly 120 and the second drive assembly 130 can respectively utilize the first drive section 121 and the second drive section 131 to output power. The power output by the first drive section 121 can act on the first sliding section 142 and the second sliding section 143 through the first cam mechanism 122, causing the first sliding section 142 and the second sliding section 143 to slide towards or away from each other along a first direction on the base assembly 110. This, in turn, drives multiple sets of relatively arranged first limiting members 141a and second limiting members 141b to move synchronously towards or away from each other, thereby achieving the aforementioned adjustment of the first length. The power output by the second drive section 131 can act on the third sliding section 143 through the second cam mechanism 132. 4 and the fourth sliding part 145, so that the third sliding part 144 and the fourth sliding part 145 slide towards each other or away from each other on the base assembly 110 along the second direction, thereby driving multiple sets of relatively arranged third limiting members 141c and fourth limiting members 141d to move towards each other or away from each other synchronously, so as to realize the aforementioned adjustment of the second length; by setting a cam mechanism between the drive part and the corresponding sliding part for power transmission, the detection fixture 100 can improve the structural compactness of the drive assembly and reduce the structural complexity of the drive assembly while realizing motion conversion, which is conducive to reducing the maintenance cost and failure probability of the first drive assembly 120 and the second drive assembly 130, and improving the miniaturization level of the detection fixture 100.

[0045] like Figures 3 to 6 As shown, in some examples, the first cam mechanism 122 includes: a first rotating plate 122a disposed on the base assembly 110; a first driving part 121 for driving the first rotating plate 122a to rotate; the rotation axis of the first rotating plate 122a is perpendicular to a first direction; a first cam 122b and a second cam 122c, both disposed on the first rotating plate 122a; the first cam 122b and the second cam 122c are both offset from the rotation axis of the first rotating plate 122a; the first cam 122b is driven to the first sliding part 142; and the second cam 122c is driven to the second sliding part 143; wherein the first cam 122b and the second cam 122c are arranged at circumferential intervals along the first rotating plate 122a.

[0046] In this technical solution, the first cam mechanism 122 may include the aforementioned first rotating plate 122a, first cam 122b, and second cam 122c. Based on the aforementioned configuration, the first cam mechanism 122 can receive the power output from the first drive unit 121 via the first rotating plate 122a. When the first drive unit 121 is running, the first rotating plate 122a can rotate relative to the base assembly 110, thereby causing the first cam 122b and the second cam 122c to generate angular displacement around the rotation axis of the first rotating plate 122a. During the aforementioned angular displacement, the positions of the first cam 122b and the second cam 122c in the first direction can also change, so that the first cam 122b and the second cam 122c can respectively drive the first sliding part 142 and the second sliding part 143 to slide in the first direction. The first cam 122b and the second cam 122c are arranged circumferentially at intervals along the first rotating plate 122a, so that the first cam 122b and the second cam 122c can form a positional difference in the first direction, so that the first cam 122b and the second cam 122c can respectively connect and drive the first sliding part 142 and the second sliding part 143 to move.

[0047] It is understood that the aforementioned first cam 122b and second cam 122c being offset from the rotation axis of the first rotating plate 122a means that the axis of the first cam 122b and the axis of the second cam 122c are both parallel to the rotation axis of the first rotating plate 122a, and the axis of the first cam 122b and the axis of the second cam 122c do not coincide with the rotation axis of the first rotating plate 122a.

[0048] Understandably, in practical applications, the first cam 122b and the second cam 122c can be arranged at 180° intervals along the circumference of the first rotating plate 122a. Thus, during the rotation of the first rotating plate 122a, the linear velocity directions of the first cam 122b and the second cam 122c can remain opposite. Correspondingly, the first cam 122b and the second cam 122c are adapted to output power in opposite directions. This allows the detection fixture 100 to easily switch the direction of rotation of the first rotating plate 122a, causing the first cam mechanism 122 to drive the first sliding part 142 and the second sliding part 143 to move towards each other or away from each other.

[0049] It is understandable that, considering that the linear displacement generated by the first cam 122b and the second cam 122c during their rotation around the rotation axis of the first rotating plate 122a also has a displacement component perpendicular to the first direction, the first sliding part 142 and the second sliding part 143 can respectively have a first elongated oval hole and a second elongated oval hole, and the length direction of the first elongated oval hole and the second elongated oval hole can both be perpendicular to the first direction. Both walls of the first elongated hole in the width direction are perpendicular to the first direction, and both walls of the second elongated hole in the width direction are perpendicular to the first direction. Both walls of the first elongated hole in the width direction abut against the periphery of the first cam 122b, and both walls of the second elongated hole in the width direction abut against the periphery of the second cam 122c. Thus, the first cam 122b is adapted to apply a thrust along the first direction to the first sliding part 142 by means of the aforementioned two walls of the first elongated hole, and the first cam 122b can generate displacement along the length direction of the first elongated hole during rotation. Consequently, the first sliding part 142 can absorb the displacement component perpendicular to the first direction generated by the first cam 122b during rotation using the first elongated hole. Similarly, the second cam 122c is adapted to apply a thrust along the first direction to the second sliding part 143 by means of the aforementioned two walls of the second elongated hole, and the second sliding part 143 can absorb the displacement component perpendicular to the first direction generated by the second cam 122c during rotation using the second elongated hole. The first cam 122b and the second cam 122c are rotatably disposed on the first rotating plate 122a, which helps to reduce the frictional resistance between the periphery of the first cam 122b and the wall of the first elongated hole, and reduce the frictional resistance between the periphery of the second cam 122c and the wall of the second elongated hole.

[0050] It is understood that when the first sliding portion 142 includes the aforementioned first guide block 142b, the first elongated hole can be formed in the first guide block 142b; when the second sliding portion 143 includes the aforementioned second guide block, the second elongated hole can be formed in the second guide block.

[0051] It is understood that the first rotating plate 122a and the first driving unit 121 are connected by transmission, and the first rotating plate 122a and the first driving unit 121 can be directly connected or indirectly connected.

[0052] For example, the first drive assembly 120 may further include a first driven pulley 123, a first driving pulley 124, a first transmission belt 125, and a first tensioning pulley 126. The first driving pulley 124 is connected to the output shaft of the first drive unit 121, the first driven pulley 123 is connected to the first rotating plate 122a, the first transmission belt 125 is connected between the first driven pulley 123 and the first driving pulley 124, and the first tensioning pulley 126 is rotatably disposed on the base assembly 110 and used to tension the first transmission belt 125. Based on this, the first drive unit 121 can drive the first rotating plate 122a to rotate through the belt drive mechanism, thereby ensuring the driving effect of the first drive unit 121 on the first rotating plate 122a while facilitating the staggered arrangement of the first drive unit 121 and the first rotating plate 122a, which is beneficial to improving the space utilization rate on the base assembly 110.

[0053] For example, the aforementioned first transmission belt 125 can be a synchronous belt.

[0054] It is understood that there can be multiple first driven pulleys 123, first cam mechanisms 122 and clamping components 140, and the first driven pulleys 123, first cam mechanisms 122 and clamping components 140 correspond one-to-one. That is, each first driven pulley 123 can drive the first sliding part 142 and the second sliding part 143 of a clamping component 140 to slide along the first direction through a first cam mechanism 122, thereby increasing the number of adjustable clamping spaces 1401 of the first drive component 120.

[0055] For example, such as Figures 2 to 5 As shown, the number of the first driven pulley 123, the first cam mechanism 122, and the clamping assembly 140 can all be two. Each clamping assembly 140 can have four of the aforementioned limiting portions 141, that is, four of the aforementioned clamping spaces 1401, so that the first drive assembly 120 can be used to adjust the first length of the eight clamping spaces 1401. It is understood that the feasible number of the first driven pulley 123, the first cam mechanism 122, and the clamping assembly 140 in practical applications is not limited to the number listed in the foregoing example. The specific number can be set according to actual needs, and no further limitations are imposed here.

[0056] It is understood that the aforementioned first rotating plate 122a is rotatably mounted on the base assembly 110. Considering the installation stability of the first rotating plate 122a, the first cam mechanism 122 may further include a first connecting plate 122h, a first bearing 122j, and a first connecting shaft 122k. The first rotating plate 122a, the first connecting plate 122h, the first bearing 122j, and the first connecting shaft 122k are arranged coaxially. The first connecting plate 122h is connected between the inner ring of the first bearing 122j and the first rotating plate 122a. The first connecting shaft 122k passes through the inner ring of the first bearing 122j. The outer ring of the first bearing 122j is fixedly mounted on the base assembly 110. The first driven pulley 123 is sleeved on the first connecting shaft 122k. Based on the aforementioned arrangement, the rotation axis of the first rotating plate 122a coincides with the axis of the first connecting shaft 122k.

[0057] like Figures 3 to 5 As shown, in some examples, the second cam mechanism 132 includes: a second rotating plate 132a, disposed on the base assembly 110, a second driving part 131 for driving the second rotating plate 132a to rotate, the rotation axis of the second rotating plate 132a being perpendicular to the second direction; a third cam 132b and a fourth cam 132c, both disposed on the second rotating plate 132a, both the third cam 132b and the fourth cam 132c being offset from the rotation axis of the second rotating plate 132a, the third cam 132b being drivenly connected to the third sliding part 144, and the fourth cam 132c being drivenly connected to the fourth sliding part 145; wherein the third cam 132b and the fourth cam 132c are arranged at circumferential intervals along the second rotating plate 132a.

[0058] In this technical solution, the second cam mechanism 132 may include the aforementioned second rotating plate 132a, third cam 132b, and fourth cam 132c. Based on the aforementioned configuration, the second cam mechanism 132 can receive the power output from the second drive unit 131 via the second rotating plate 132a. When the second drive unit 131 is running, the second rotating plate 132a can rotate relative to the base assembly 110, thereby causing the third cam 132b and fourth cam 132c to generate angular displacement around the rotation axis of the second rotating plate 132a. During the process of the third cam 132b and fourth cam 132c generating the aforementioned angular displacement, the third cam 132b and fourth cam 132c in the second direction... The positions of the upper parts can also change, so that the third cam 132b and the fourth cam 132c can respectively drive the third sliding part 144 and the fourth sliding part 145 to slide in the second direction; the third cam 132b and the fourth cam 132c are arranged circumferentially along the second rotating plate 132a, so that the third cam 132b and the fourth cam 132c can form a positional difference in the second direction, so that the third cam 132b and the fourth cam 132c can respectively connect and drive the third sliding part 144 and the fourth sliding part 145 to move.

[0059] It is understood that the aforementioned deviation of the third cam 132b and the fourth cam 132c from the rotation axis of the second rotating plate 132a means that the axis of the third cam 132b and the axis of the fourth cam 132c are both parallel to the rotation axis of the second rotating plate 132a, and the axis of the third cam 132b and the axis of the fourth cam 132c do not coincide with the rotation axis of the second rotating plate 132a.

[0060] Understandably, in practical applications, the third cam 132b and the fourth cam 132c can be arranged at 180° intervals along the circumference of the second rotating plate 132a. Thus, during the rotation of the second rotating plate 132a, the linear velocity directions of the third cam 132b and the fourth cam 132c can remain opposite. Accordingly, the third cam 132b and the fourth cam 132c are adapted to output power in opposite directions. This allows the detection fixture 100 to easily switch the direction of rotation of the second rotating plate 132a, causing the second cam mechanism 132 to drive the third sliding part 144 and the fourth sliding part 145 to move towards each other or away from each other.

[0061] Understandably, considering that the linear displacement generated by the third cam 132b and the fourth cam 132c during their rotation around the rotation axis of the second rotating plate 132a also includes a displacement component perpendicular to the second direction, the third sliding part 144 and the fourth sliding part 145 can respectively be provided with a third elongated oval hole and a fourth elongated oval hole, the length directions of which can both be perpendicular to the second direction. The two walls of the third elongated hole in the width direction are perpendicular to the second direction, and the two walls of the fourth elongated hole in the width direction are also perpendicular to the second direction. The two walls of the third elongated hole in the width direction abut against the periphery of the third cam 132b, and the two walls of the fourth elongated hole in the width direction abut against the periphery of the fourth cam 132c. Thus, the third cam 132b is adapted to apply a thrust along the second direction to the third sliding part 144 through the aforementioned two walls of the third elongated hole, and the third cam 132b can generate displacement along the length direction of the third elongated hole during rotation. Consequently, the third sliding part 144 can absorb the displacement component perpendicular to the second direction generated by the third cam 132b during rotation using the third elongated hole. Similarly, the fourth cam 132c is adapted to apply a thrust along the second direction to the fourth sliding part 145 through the aforementioned two walls of the fourth elongated hole, and the fourth sliding part 145 can absorb the displacement component perpendicular to the second direction generated by the fourth cam 132c during rotation using the fourth elongated hole. The third cam 132b and the fourth cam 132c are rotatably mounted on the second rotating plate 132a, which helps to reduce the frictional resistance between the periphery of the third cam 132b and the wall of the third elongated hole, and reduce the frictional resistance between the periphery of the fourth cam 132c and the wall of the fourth elongated hole.

[0062] It is understood that when the third sliding part 144 includes the aforementioned third guide block 144b, the third elongated hole can be formed in the third guide block 144b; when the fourth sliding part 145 includes the aforementioned fourth guide block, the fourth elongated hole can be formed in the fourth guide block.

[0063] It is understood that the second rotating plate 132a and the second driving unit 131 are connected by transmission, and the second rotating plate 132a and the second driving unit 131 can be directly connected or indirectly connected.

[0064] For example, the second drive assembly 130 may further include a second driven pulley 133, a second driving pulley 134, a second transmission belt 135, and a second tensioning pulley 136. The second driving pulley 134 is connected to the output shaft of the second drive unit 131, the second driven pulley 133 is connected to the second rotating plate 132a, the second transmission belt 135 is connected between the second driven pulley 133 and the second driving pulley 134, and the second tensioning pulley 136 is rotatably disposed on the base assembly 110 and used to tension the second transmission belt 135. Based on this, the second drive unit 131 can drive the second rotating plate 132a to rotate through the belt drive mechanism, thereby ensuring the driving effect of the second drive unit 131 on the second rotating plate 132a while facilitating the staggered arrangement of the second drive unit 131 and the second rotating plate 132a, which is beneficial to improving the space utilization rate on the base assembly 110.

[0065] For example, the aforementioned second transmission belt 135 can be a synchronous belt.

[0066] It is understood that there can be multiple second driven pulleys 133, second cam mechanisms 132 and clamping components 140, and each second driven pulley 133, second cam mechanism 132 and clamping component 140 can correspond one-to-one. That is, each second driven pulley 133 can drive the third sliding part 144 and the fourth sliding part 145 of a clamping component 140 to slide along the second direction through a second cam mechanism 132, thereby increasing the number of adjustable clamping spaces 1401 of the second drive component 130.

[0067] For example, such as Figures 2 to 5As shown, the number of the second driven pulley 133, the second cam mechanism 132, and the clamping assembly 140 can all be two. Each clamping assembly 140 can have four of the aforementioned limiting portions 141, that is, four of the aforementioned clamping spaces 1401, so that the second drive assembly 130 can be used to adjust the second length of the eight clamping spaces 1401. It is understood that the feasible number of the second driven pulley 133, the second cam mechanism 132, and the clamping assembly 140 in practical applications is not limited to the number listed in the foregoing example. The specific number can be set according to actual needs, and no further limitations are imposed here.

[0068] It is understood that the aforementioned second rotating plate 132a is rotatably mounted on the base assembly 110. Considering the installation stability of the second rotating plate 132a, the second cam mechanism 132 may further include a second connecting plate, a second bearing, and a second connecting shaft. The second rotating plate 132a, the second connecting plate, the second bearing, and the second connecting shaft are arranged coaxially. The second connecting plate is connected between the inner ring of the second bearing and the second rotating plate 132a. The second connecting shaft passes through the inner ring of the second bearing. The outer ring of the second bearing is fixedly mounted on the base assembly 110. The second driven pulley 133 is sleeved on the second connecting shaft. Based on the aforementioned arrangement, the rotation axis of the second rotating plate 132a coincides with the axis of the second connecting shaft.

[0069] like Figure 7 As shown, in some examples, the first drive unit 121 includes a first servo motor 121a and a first mounting plate 121b, the first mounting plate 121b being disposed on the base assembly 110, the first servo motor 121a being disposed on the first mounting plate 121b, and a first cam mechanism 122 being connected to the first servo motor 121a; the second drive unit 131 includes a second servo motor 131a and a second mounting plate 131b, the second mounting plate 131b being disposed on the base assembly 110, the second servo motor 131a being disposed on the second mounting plate 131b, and a second cam mechanism 132 being connected to the second servo motor 131a.

[0070] In this technical solution, the first drive unit 121 includes the aforementioned first servo motor 121a and the aforementioned first mounting plate 121b; based on this, the first drive unit 121 can use the first servo motor 121a to output power, so that the first drive unit 121 can have good power output accuracy, which is conducive to improving the adjustment accuracy of the first length and providing a guarantee for the execution effect of quality inspection operation.

[0071] In this technical solution, the second drive unit 131 includes the aforementioned second servo motor 131a and the aforementioned second mounting plate 131b; based on this, the second drive unit 131 can use the second servo motor 131a to output power, thereby the second drive unit 131 can have good power output accuracy, which is conducive to improving the adjustment accuracy of the second length and providing a guarantee for the execution effect of quality inspection operations.

[0072] like Figure 7 As shown, in some examples, the base assembly 110 includes: a first base plate 111; a second base plate 112, on which both the first drive assembly 120 and the second drive assembly 130 are disposed; and a support plate 113 connected between the first base plate 111 and the second base plate 112, wherein the support plate 113, the first base plate 111, and the second base plate 112 form an installation space 1101; wherein at least a portion of the first drive assembly 120 and at least a portion of the second drive assembly 130 are arranged within the installation space 1101.

[0073] In this technical solution, the base assembly 110 may include the aforementioned first base plate 111, second base plate 112, and support plate 113. Based on the aforementioned configuration, the base assembly 110 can use the first base plate 111 and support plate 113 to support the second base plate 112, and use the second base plate 112 to provide structural support for the aforementioned drive assembly and clamping assembly 140. Furthermore, it can use the aforementioned installation space 1101 to accommodate at least a portion of the drive assembly, thereby providing structural protection for the drive assembly, reducing the risk of structural damage to the drive assembly, ensuring the operational stability and reliability of the drive assembly, and facilitating the continuous and stable operation of the testing work.

[0074] It is understandable that there can be multiple support plates 113.

[0075] For example, the aforementioned driving pulley, driven pulley, transmission belt and tensioner can be arranged within the aforementioned installation space, thereby improving the operational stability of the belt drive mechanism.

[0076] like Figure 7 As shown, in some examples, the base assembly 110 further includes a connecting bearing 114, the first base plate 111 having a through-shaft hole, the connecting bearing 114 being embedded in the through-shaft hole, and the outer ring of the connecting bearing 114 being fixedly connected to the first base plate 111.

[0077] In this technical solution, the base assembly 110 may further include the aforementioned connecting bearing 114. Based on the aforementioned configuration, the base assembly 110 is adapted to connect to an external driving device via the connecting bearing 114, so that the testing fixture 100 can rotate under the drive of the aforementioned driving device, which facilitates the testing fixture 100 in adjusting the position of the tested piece 200 during the testing process, thereby improving the ease of use of the testing fixture 100.

[0078] For example, the base assembly 110 may also include a bearing plate 115, which is embedded in the through-shaft hole, and the outer ring of the aforementioned connecting bearing 114 is fixedly disposed on the aforementioned bearing plate 115.

[0079] For example, the base assembly 110 may also include a plurality of side support plates 116 disposed on the side of the second base plate 112 away from the mounting space 1101, wherein at least one side support plate 116 is fixedly connected to the slider of the aforementioned third guide rail 144a, and at least one side support plate 116 is fixedly connected to the slider of the aforementioned fourth guide rail.

[0080] A detection system is provided according to a second aspect of the present disclosure, comprising: a detection fixture 100 as described in any of the first aspects above.

[0081] Since the detection system proposed in this disclosure includes the detection fixture 100 as described in any of the first aspects above, it possesses all the beneficial effects of the detection fixture 100, which will not be elaborated here.
