[0037] Figure 1 The structural schematic diagram of the detection tooling provided by the embodiment of the present utility model is shown. Refer to Figure 1, this embodiment provides a detection tooling, which can directly lift the workpiece to be detected carried on the carrier trolley to the detection position for subsequent detection. This avoids the risk of dropping during the process of first hoisting and then placing the workpiece to be detected at the detection position due to the instability of the hoisting process, and also avoids the problem of position deviation of the workpiece to be detected after it is placed at the detection position. In this embodiment, the workpiece to be detected is specifically a vehicle-mounted battery pack. In other embodiments, the workpiece to be detected can also be other structures with larger volumes.

[0038] The detection tooling provided in this embodiment includes a lifting device 300 and two bracket assemblies 100 that are parallel to each other and spaced apart. A width-adjustable walking channel 200 is formed between the two bracket assemblies 100. The walking channel 200 is configured to allow the carrier trolley to pass through, and the workpiece to be detected is placed on the carrier trolley. Through the walking channel 200, the traveling route of the carrier trolley can be restricted, facilitating the transportation of the workpiece to be detected to the lifting device 300 in a certain direction. The lifting device 300 can lift the workpiece to be detected to the detection position. In this embodiment, the walking channel 200 is specifically a straight channel. In other embodiments, the walking channel 200 can also be bent or looped according to actual needs.

[0039] Specifically, the bracket assembly 100 includes a bracket body 110. The bracket body 110 includes a base 111, a vertical frame 112, and support feet 113. The base 111 is in the shape of a rectangular plate or a rectangular frame structure, and the lifting device 300 is arranged on the base 111. The support feet 113 are multiple, and the multiple support feet 113 are evenly spaced along the length direction at the bottom of the base 111 for stably supporting the base 111.

[0040] More specifically, the bracket assembly 100 further includes a limiting component. Limiting components are arranged on one side of the two bracket bodies 110 facing each other. The walking channel 200 is formed between the two limiting components, and the lifting device 300 is arranged on the side of the limiting component facing the corresponding bracket body 110. The limiting component includes a limiting member 130 connected to the bracket body 110. The limiting members 130 are arranged on one side of the two bracket bodies 110 facing each other, and the walking channel 200 is formed between the two limiting members 130.

[0041] More specifically, the bracket assembly 100 further includes a telescopic driving assembly 120. The fixed end of the telescopic driving assembly 120 is disposed on the bracket body 110, and the output end of the telescopic driving assembly 120 is connected to the limiting member 130. The distance between the limiting member 130 and the bracket body 110 can be adjusted by the telescopic driving assembly 120. The distance between the two limiting members 130 can be adjusted by the corresponding telescopic driving assembly 120, so as to realize the adjustment of the width of the walking passage 200 to be suitable for the passing of carrier trolleys of different width dimensions. In this embodiment, the telescopic driving assembly 120 is specifically a cylinder. The limiting member 130 is specifically a long strip-shaped rectangular plate structure, and its length is not less than the length of the base 111.

[0042] More specifically, the bracket assembly 100 further includes a connecting block 170. The connecting block 170 is fixedly connected to the output end of the telescopic driving assembly 120, and is supported and fixedly connected to one end of the bottom of the limiting member 130, and abuts against the side of the base 111. When the output end of the telescopic driving assembly 120 expands and contracts, the connecting block 170 can abut against the side of the base 111 and move, so as to drive the limiting member 130 away from or close to the base 111. Through the connecting block 170, the connection area between the limiting member 130 and the telescopic driving assembly 120 can be increased, and the connecting block 170 can be used to reliably support the limiting member 130, ensuring the stability during the process of adjusting the position of the limiting member 130.

[0043] Continue to refer to Figure 1 , the limiting assembly further includes a limiting roller 140. The limiting roller 140 is disposed on the upper end surface of the limiting member 130 and can abut against the side of the carrier trolley. The axis direction of the limiting roller 140 is perpendicular to the extending direction of the walking passage 200. That is to say, the limiting rollers 140 on the two limiting members 130 can respectively abut against the opposite sides of the carrier trolley, so as to reduce the friction force received by the carrier trolley during the movement process, and can further accurately limit the movement of the carrier trolley along the walking passage 200. Furthermore, when the carrier trolley moves to the position where the lifting device 300 is located, the position state of the workpiece to be detected carried on the carrier trolley can meet the requirements of the detection position, so that it is no longer necessary to calibrate the position state of the workpiece to be detected, and the lifting device 300 can be directly used for lifting.

[0044] Specifically, a plurality of the limiting rollers 140 are provided, and the plurality of limiting rollers 140 are arranged on the limiting member 130 at intervals along the extending direction of the walking passage 200. Through the above arrangement, the position state of the carrier trolley can be corrected multiple times during the whole process of the carrier trolley moving along the walking passage 200.

[0045] Specifically, there are at least two telescopic drive assemblies 120, and at least two of the telescopic drive assemblies 120 are arranged in sequence along the extension direction of the bracket body 110. In this embodiment, there are two telescopic drive assemblies 120, and the two telescopic drive assemblies 120 are respectively arranged at both ends in the extension direction of the base 111. Through the above settings, it can be ensured that the forces at both ends of the limiting member 130 are balanced during movement, avoiding skew.

[0046] Figure 2 Show Figure 1 A partial schematic view of the structure marked as A in Figure 1 And Figure 2 As a preference, a guiding portion 131 is provided at the end of the limiting member 130. The guiding portions 131 are provided on both of the two limiting members 130 oppositely arranged on both sides of the walking passage 200, so as to form an inlet portion with a larger width and in a trumpet shape at the end of the walking passage 200, provide guidance for the carrier cart, facilitate the carrier cart to enter the walking passage 200, and can prevent the problem that the carrier cart collides with the end of the limiting member 130 and is damaged when driving into the walking passage 200.

[0047] Figure 3 Show Figure 1 A partial schematic view of the structure marked as B in Figure 1 And Figure 3 The bracket assembly 100 further includes a support plate member 150, the support plate member 150 is connected to the bracket body 110, and the limiting member 130 is slidably arranged on the support plate member 150. That is to say, the support plate member 150 can serve as an extension of the bracket body 110 to provide reliable support for the limiting member 130.

[0048] Specifically, there are multiple support plate members 150, and the multiple support plate members 150 are arranged on the bracket body 110 at equal intervals along the length direction, so as to ensure the uniformity of the force when supporting the limiting member 130, and at the same time effectively improve the installation stability of the limiting member 130 and the reliability of the limiting member 130 to limit the carrier cart.

[0049] Specifically, continue to refer to Figure 3 The limiting member 130 is provided with a waist-shaped hole 132 at the position corresponding to the support plate member 150, and a fastening bolt 133 is arranged in the waist-shaped hole 132. The long axis direction of the waist-shaped hole 132 is arranged parallel to the position adjustment direction of the limiting member 130. When it is necessary to adjust the position of the limiting member 130 to adjust the width of the walking passage 200, loosen the fastening bolt 133, and then adjust the position of the limiting member 130 within the length range of the long axis of the waist-shaped hole 132.

[0050] More specifically, there are multiple waist-shaped holes 132. In this embodiment, every two waist-shaped holes 132 form a group, which is arranged corresponding to one support plate 150. Each group of waist-shaped holes 132 has two. The two waist-shaped holes 132 are arranged at intervals along the extension direction of the walking channel 200, and the connection between the support plate 150 and the limiter 130 is achieved by fastening bolts 133 corresponding to the waist-shaped holes 132 one by one. Through the above arrangement, the force uniformity of the support plate 150 and the reliability of the connection between each support plate 150 and the limiter 130 are improved.

[0051] Figure 4 Show Figure 1 A partial schematic diagram of the structure marked with C. Figure 1 and Figure 4 The lifting device 300 provided in this embodiment includes a lifting drive assembly 310 and a support assembly 320. The lifting drive assembly 310 is arranged on the bracket assembly 100 and is transmission-connected to the support assembly 320. It should be noted that when the workpiece to be inspected is placed on the transport trolley, the bottom height thereof is higher than the highest point of the lifting device 300. The support assembly 320 is located below the workpiece to be inspected in the vertical direction. The support assembly 320 is used to support the workpiece to be inspected and can be raised and lowered relative to the bracket assembly 100 driven by the lifting drive assembly 310 to lift or lower the workpiece to be inspected on the transport trolley.

[0052] Specifically, the vertical frame 112 is vertically fixed to one side of the base 111. The support assembly 320 is slidably connected to the vertical frame 112 so as to be able to be raised and lowered. The vertical frame 112 can guide the support assembly 320 when it moves, so that the support assembly 320 can be raised and lowered along the height direction of the vertical frame 112. Through the above arrangement, the stability of the support assembly 320 can be improved.

[0053] Specifically, the lifting device 300 further includes a wedge-shaped transmission member 330, which is connected to the output end of the lifting drive assembly 310, and the bottom of the support assembly 320 is slidably abutted against the inclined bearing surface of the wedge-shaped transmission member 330. In this embodiment, the lifting drive assembly 310 is a telescopic cylinder. The driving end of the lifting drive assembly 310 is fixedly arranged on the base 111, and the output end of the lifting drive assembly 310 can be telescopic in the horizontal direction, specifically, along the length direction of the base 111, that is, the extension direction of the walking channel 200, thereby driving the wedge-shaped transmission member 330 to move relative to the support assembly 320 in the horizontal direction. Since the support assembly 320 is movably located on the inclined bearing surface of the wedge-shaped transmission member 330, the support assembly 320 moves along the inclined bearing surface, thereby being lifted and lowered relative to the base 111 on the vertical frame 112.

[0054] More specifically, the support assembly 320 includes a support member and rollers 340 disposed at the bottom of the support member. The top end of the support member is used to support the workpiece to be detected. The rotation axis of the roller 340 is disposed parallel to the bottom surface of the support assembly 320, and the roller 340 is rollably abutted against the inclined bearing surface. Through the above arrangement, the smoothness of the movement of the support assembly 320 along the inclined bearing surface can be improved, and thus the smoothness of the lifting action of the support assembly 320 can be ensured.

[0055] More specifically, with continued reference to Figure 4 , a second sliding connector 331 is fixedly disposed on one side of the wedge transmission member 330 facing the base 111. A third sliding connector 114 is fixedly disposed on one side of the base 111 facing the wedge transmission member 330. The second sliding connector 331 and the third sliding connector 114 are slidably connected to each other, thereby providing guidance for the sliding of the wedge transmission member 330 on the base 111 and reducing the friction force of the relative movement between the two.

[0056] Preferably, the wedge transmission members 330 and the support assemblies 320 are respectively multiple. The multiple wedge transmission members 330 are spaced along the movement direction of the carrier cart, that is, the extending direction of the walking channel 200, and correspond to the multiple support assemblies 320 one by one. The multiple wedge transmission members 330 are sequentially connected by a connecting rod 350. Referring to Figure 1 , the connecting rod 350 has a straight rod structure and is fixedly connected between two adjacent wedge transmission members 330. When the lifting drive assembly 310 drives one wedge transmission member 330 to move, the multiple wedge transmission members 330 can act and lift simultaneously to support the workpiece to be detected with a larger volume at the same time, thereby improving the stability.

[0057] Figure 5 Show Figure 1 A partial schematic view of the structure marked as D in Figure 5 . A lifting limit track 160 is provided on the support assembly 100. In this embodiment, the lifting limit track 160 is specifically disposed on the vertical frame 112. The lifting limit track 160 is disposed parallel to the lifting direction of the support assembly 320, and the support assembly 320 is slidably connected to the lifting limit track 160. Through the above arrangement, the reliability of the lifting of the support assembly 320 along the height direction of the vertical frame 112 can be ensured, and deviation can be prevented.

[0058] Specifically, a first sliding connector 321 is disposed on one side of the support assembly 320 facing the vertical frame 112. The first sliding connector 321 is slidably connected to the lifting limit track 160, thereby providing guidance for the sliding of the support assembly 320 on the vertical frame 112 and reducing the friction force of the relative movement between the two.

[0059] Specifically, a groove is provided on the side of the first sliding connector 321 facing away from the lifting limit track 160, and the support assembly 320 can be embedded in the groove to achieve the detachable assembly of the first sliding connector 321 and the support assembly 320. The support assembly 320 can be replaced according to the specific required height of the workpiece to be detected that needs to be supported, further improving the flexibility of the detection tooling and expanding the use range of the detection tooling.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
