That is, the orthographic projection of the first accommodation space on the base 121 covers the orthographic projection of the workpiece 200 on the base 121, and the plurality of clamp assemblies 122 are located on the outer periphery of the workpiece 200 with the workpiece 200 clamped by the plurality of clamp assemblies 122.

For example, in the example of fig. 5-8, four clamping assemblies 122 are shown, the base 121 is generally rectangular in configuration, and the four clamping assemblies 122 are disposed adjacent to four corners of the base 121, respectively. Each of the clamping assemblies 122 is movable between a clamping position for clamping the workpiece 200 and an unclamping position for unclamping the workpiece 200, with the clamping assembly 122 in the clamping position, the workpiece 200 being clamped by four of the clamping assemblies 122, and with the four clamping assemblies 122 each being located at a corresponding corner of the workpiece 200. When welding the workpiece 200, the welding robot 160 may be located at the middle of the workpiece 200, having a large working space.

Here, it should be noted that "the middle portion of the workpiece 200" is to be broadly understood in the present application, and refers to a portion closer to the center of the workpiece 200 than the corners of the workpiece 200, and is not limited to the center of the workpiece 200.

Therefore, the clamping assemblies 122 are arranged at the end parts of the base 121, and the first accommodating space surrounding the workpiece 200 is formed among the clamping assemblies 122, so that under the condition that the clamping assemblies 122 clamp the workpiece 200, the corners of the workpiece 200 can be fixed, the middle position of the workpiece 200 can be prevented from being occupied, and the working space is expanded to the maximum extent. Moreover, the clamping assembly 122 can be prevented from interfering with other structures in the production process of the workpiece 200, the workpiece 200 can be clamped at one time in the whole production process, the repeated replacement of the tool sewage box clamp 120 is avoided, the cost is reduced, the labor intensity of operators can be reduced, the production efficiency is improved, and potential safety hazards caused in the repeated clamping process are avoided.

The four clamping assemblies 122 shown in fig. 5-8 are for illustrative purposes, but it will be apparent to one of ordinary skill after reading the disclosure herein that the disclosure applies to other numbers of clamping assemblies 122 and falls within the scope of the disclosure.

In one embodiment, referring to fig. 8, at least one clamping assembly 122 includes a plurality of clamping portions, each of the plurality of clamping portions being located on three adjacent faces of the workpiece 200 corresponding to a same vertex when the corresponding clamping assembly 122 is in the clamped state.

Illustratively, the workpiece 200, such as a dirt box, may be formed in a rectangular parallelepiped structure. With the clamping assemblies 122 in the clamping position, each clamping assembly 122 is in a clamped state, and the clamping portions are clamped at the corners of the workpiece 200. Wherein at least one clamping portion of each clamping assembly 122 presses against the upper surface of the workpiece 200, and at least two clamping portions of each clamping assembly 122 respectively clamp two adjacent side surfaces of the workpiece 200.

Therefore, through the arrangement, the clamping parts can stably clamp the workpiece 200, and the phenomenon that the workpiece 200 shakes to influence the operation on the workpiece 200 is avoided, so that the production process of the workpiece 200 is more reliable.

In one embodiment, with reference to fig. 5 to 8, the base 121 is provided with a support rod 1214, the plurality of clamping portions are a first clamping portion 1221, a second clamping portion 1222 and a third clamping portion 1223, respectively, the first clamping portion 1221 clamps the top surface of the workpiece 200, and the second clamping portion 1222 and the third clamping portion 1223 clamp two side surfaces of the workpiece 200 when the corresponding clamping assembly 122 is in the clamping state; the support rods 1214 are supported on the bottom surface of the workpiece 200.

With such an arrangement, the first clamping portion 1221 and the supporting rod 1214 can effectively limit the movement of the workpiece 200 in the vertical direction, and the second clamping portions 1222 and the third clamping portions 1223 of the plurality of clamping assemblies 122 can effectively limit the movement of the workpiece 200 in the front-back direction and the left-right direction, so that the entire dirt box clamp 120 can reliably clamp the workpiece 200, and the clamping stability of the workpiece 200 is ensured.

Therefore, on one hand, the contact area between the first clamping portion 1221 and the workpiece 200 is relatively small, and the first clamping portion 1221 occupies a small space while pressing the workpiece 200, so that interference with other structures can be avoided, and space layout of other structures is facilitated; on the other hand, the contact area of the second clamping portion 1222 and the third clamping portion 1223 with the workpiece 200 is relatively large, and the pressure can be reduced while the workpiece 200 is effectively clamped, so that the deformation of the workpiece 200 due to excessive force can be avoided.

In an alternative embodiment, the flatness of the surface of the base 121 on the side away from the clamping assembly 122 satisfies the predetermined condition.

The border 1215 can include first and second sides opposite each other, and third and fourth sides opposite each other. Wherein the first and second sides are the long sides of the frame 1215, and the third and fourth sides are the short sides of the frame 1215. The two support rods 1214 are respectively a first rod and a second rod, and the length of the first rod is greater than that of the second rod. The first pole is established on first edge, the one end on first pole and the outside surface parallel and level on first edge to reduce occupation space, the other end on first pole inwards extends, and the second pole is established on the second edge, the one end on second pole and the outside surface parallel and level on second edge, in order to reduce occupation space, the other end of second pole inwards extends, and the above-mentioned other end of second pole and first pole is relative each other.

For example, six limiting portions 1213 are shown in the example of fig. 7, and the six limiting portions 1213 constitute two limiting group, each of which includes three limiting portions 1213. One of the two limiting groups is disposed on the outer side surface of the first side, and the other of the two limiting groups is disposed on the outer side surface of the second side. Two limiting parts 1213 in each limiting group are respectively located at two ends of the corresponding first edge or second edge, and the other limiting part 1213 in each limiting group is located in the middle of the corresponding first edge or second edge.

Therefore, the limiting part 1213 can effectively limit the movement of the base 121 relative to the transmission rail 112, so as to prevent the base 121 from displacing the workpiece 200, and ensure that the base 121 and the workpiece 200 can be driven by the transmission rail 112 to move along the conveying direction of the transmission rail 112 during the transmission of the transmission rail 112, thereby improving the production reliability of the workpiece 200.

For example, in the example of fig. 9 and 11, the first connection rod 1331 extends horizontally and both second connection rods 1332 extend vertically. The first driving means 1311 may be provided on the second connection rod 1332. The lift assembly 131 may also include a mounting bar, which may be formed with the support 1312 in an "L" shaped configuration. Wherein the mounting rods are connected between the supports 1312 and the corresponding second connecting rods 1332, and the mounting rods are perpendicular to the first connecting rods 1331.

Thus, by making the supporting member 1312 be a rod-like structure, the size of the supporting member 1312 is relatively small, so that the occupied space can be reduced and the arrangement can be more convenient while the workpiece 200 is effectively supported. By the support rods 1214 being parallel to the first connecting rod 1331, it is ensured that the workpiece 200 can be kept in a horizontal state under the supporting action of the support pieces 1312 when the workpiece 200 is in the lifting mode, so that the lifting stability of the workpiece 200 can be improved, and the workpiece 200 is prevented from being inclined during the lifting process.

For example, the protruding parts 1212 may be two, the two protruding parts 1212 are located at the sides of the third and fourth sides, respectively, and the two protruding parts 1212 protrude in the direction away from each other, respectively. The second driving device 1321 may be a motor. When the workpiece 200 needs to be rotated, the filth box holder 120 and the workpiece 200 may be lifted by the lifting assembly 131, and the protrusion 1212 may be separated from the clamp during the lifting of the filth box holder 120 and the workpiece 200. The clamp is then clamped to the boss 1212. Then, the second driving means 1321 is controlled to operate, the motor shaft can rotate the clamping member, and since the clamping member is fixed relative to the protrusion 1212 at this time, the dirt box holder 120 and the work 200 can rotate together with the clamping member, and the elevating portion 1211 can be separated from the supporter 1312 during the rotation of the dirt box holder 120 and the work 200.
