All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The hoisting clamp provided by the utility model is described below with reference to fig. 1 to 3.

As shown in fig. 1, in the present embodiment, the lifting jig includes a jig main body 10, a clamping assembly, a transmission assembly, and a driving assembly. The clamp body 10 is used for being connected with hoisting equipment such as a crane, a robot and the like, and the clamping assembly, the transmission assembly and the driving assembly are installed on the clamp body 10 so as to clamp a workpiece. In the present embodiment, the battery module is used as a workpiece to describe the hoisting fixture, but the hoisting fixture can also be used for hoisting other structures such as a battery box, and the utility model is not limited in particular.

Specifically, as shown in fig. 1 and 2, the clamping assemblies are movably connected to the clamp body 10, and the two clamping assemblies can move in opposite directions along the X-axis direction to clamp and fix a workpiece. The transmission assembly comprises a first connecting rod 31 and two second connecting rods 32, the first connecting rod 31 is positioned between the two clamping assemblies, two ends of the first connecting rod 31 are respectively connected with one second connecting rod 32, and each second connecting rod 32 is correspondingly connected with one clamping assembly in a position-adjustable mode. The driving component is fixedly connected to the clamp body 10 and is in transmission connection with the first connecting rod 31, and the driving component can drive the first connecting rod 31 to swing, so that the second connecting rod 32 moves along the X-axis direction, and accordingly the two clamping components are pulled to move in opposite directions to clamp a workpiece, and the workpiece can enter the two clamping components conveniently through the separating motion, or the workpiece to be clamped can be released through the separating motion.

In use, the first link 31 is driven to swing reversely (in this embodiment, the first link is rotated counterclockwise in the top view of fig. 1) by the driving component, that is, the two second links 32 are moved away from each other, and the two clamping components are pulled away from each other, so that the lifting fixture can be moved by the lifting device, and the battery module enters between the two clamping components. After the battery module is located between the two clamping assemblies, the driving assembly drives the first connecting rod 31 to swing forward (in this embodiment, rotate clockwise along the top view of fig. 1), that is, the two second connecting rods 32 move in opposite directions, and the two clamping assemblies are pulled to approach each other, so that the battery module can be clamped between the two clamping assemblies. Finally, the hoisting clamp and the battery module can be hoisted together through hoisting equipment so as to assemble the battery module into the battery box. In this embodiment, the driving component and the first link 31 are directly connected in a hinged manner, and in some other embodiments, other transmission structures may be used to indirectly connect between the driving component and the first link 31, so long as the driving component can pull the two clamping components to make opposite movement and opposite movement through the first link 31.

When the battery modules with different sizes are required to be hoisted, the opening and closing travel range of the hoisting clamp can be changed by changing the position of the clamping assembly connected to the second connecting rod 32. For example, for a battery module having a small dimension in the X-axis direction (this dimension is referred to as the width of the work piece in the present utility model), the clamping assembly is attached to the end of the second link 32 near the first link 31, and the opening and closing stroke range of the lifting jig is small (e.g., 40cm to 60 cm); for the battery module with larger dimension along the X-axis direction, the clamping component is connected to one end of the second connecting rod 32 far away from the first connecting rod 31, so that the opening and closing travel range of the hoisting clamp is larger (for example, 50cm-70 cm). In the present embodiment, the connection manner of the clamping assembly and the second link 32 is not particularly limited, and may be a threaded connection, a snap connection, or the like, so long as a detachable connection is formed.

The driving assembly and the transmission assembly drive the two clamping assemblies to be close to each other and far away from each other, so that the workpiece can be clamped and fixed between the two clamping assemblies, and the opening and closing travel range of the lifting clamp is adjustable by adjusting the connection position of the second connecting rod 32 in the clamping assemblies and the transmission assembly, so that the clamping requirements of the workpieces with different widths are met, and the lifting clamp is suitable for lifting work of the workpieces with different widths.

Referring to fig. 2 and 3, the clamp body 10 adopts a quadrangular frame structure constructed by sectional materials, and the quadrangular frame structure is connected with a suspension member through which the clamp body 10 and a lifting device can be fixedly connected. Specifically, four vertex positions of the quadrangular frame structure are respectively provided with a lifting ring 17, and the lifting rings 17 can be connected with lifting equipment. The profile extending along the X-axis direction is connected with a slide rail 12, the slide rail 12 extends along the X-axis direction, two ends of the slide rail 12 are respectively provided with at least one sliding block 11 in a sliding manner, and the clamping assembly is connected with the sliding blocks 11. In this embodiment, the transmission assembly only plays a role in pulling the clamping assembly and the sliding block 11 to slide along the sliding rail 12, and the weight of the workpiece is transferred to the hoisting device through the clamping assembly, the sliding block 11, the sliding rail 12 and the clamp body 10, so that the transmission assembly can be prevented from receiving a larger load, and the failure rate of the hoisting clamp can be reduced.

Optionally, in this embodiment, a rotary connector 33 is adjustably mounted on the second link 32. The rotation connector 33 includes a rotation portion and a fixing portion, and the rotation portion is rotatably connected to the fixing portion about the Z-axis direction. The fixed part is connected to the clamping assembly, the rotating part is provided with a through hole, and the second connecting rod 32 passes through the through hole. Through rotating the connecting piece 33, the movement of the second connecting rod 32 can be decomposed into the movement along the X-axis direction and the movement along the Y-axis direction, the clamping assembly only moves along the movement along the X-axis direction, the stress between the sliding block 11 and the sliding rail 12 along the Y-axis direction is reduced, the smoothness of the movement of the sliding block 11 is improved, and the service life of the hoisting clamp is prolonged. Of course, in some other embodiments, a similar effect can be achieved by providing a rotating connection member 33 or a swinging connection member at the connection portion of the first link 31 and the second link 32, which is not particularly limited in the present utility model.

Further alternatively, the side wall of the via hole is provided with a threaded hole to which a stop screw is screwed and abuts against the surface of the second link 32, thereby fixedly connecting the rotary link 33 to the second link 32 in a position-adjustable manner. When the connection position needs to be adjusted, the stop screw is only required to be unscrewed, the length of the second connecting rod 32 penetrating through the through hole is adjusted, and then the stop screw is required to be screwed.

As shown in fig. 1 and 2, in the present embodiment, the clamp body 10 is fixedly connected with a first connecting member 13, and two ends of the first connecting member 13 are respectively fixedly connected with a profile extending along the X-axis direction. The driving assembly includes an elbow clip 41, wherein the elbow clip 41 is fixedly connected to the first connecting member 13, and an output end thereof is connected to the first connecting rod 31. When the elbow clamp 41 is closed, the two clamping components are kept at a preset distance, the preset distance is the minimum stroke of the hoisting clamp, and the minimum stroke is equal to or slightly larger than the dimension of the battery module along the X-axis direction, so that the two clamping components can clamp the battery module with smaller clamping force, extrusion damage to the battery module is avoided, and the self-locking function of the elbow clamp 41 when closed can also ensure that the battery module is stably kept between the two clamping components. When the toggle clamp 41 is changed from closed to fully opened, the output end drives the first connecting rod 31 to swing reversely, and at the moment, the two clamping assemblies move in principle mutually, so that the battery module can be released from the hoisting clamp.

Further, in the present embodiment, as shown in fig. 3, the clamping assembly includes a clamping member fixing member 21 and a clamping member 22, where the clamping member fixing member 21 is connected to the slider 11, so that the clamping member fixing member 21 can move along the X-axis direction to drive the clamping member 22 to clamp and fix the workpiece to be lifted. In this embodiment, two profiles of the quadrangular frame structure extending in the X-axis direction are each connected to one slide rail 12, and each slide rail 12 is slidably connected to two sliders 11. The two clamping piece fixing pieces 21 are arranged along the Y-axis direction, and each end part of the two clamping piece fixing pieces 21 is connected with one sliding block 11, so that the pulling force on the workpiece is uniformly distributed on the two sliding rails 12, and the stability during lifting is improved.

In the present embodiment, at least two clips 22 are mounted on the same clip fixing member 21 in alignment in the Y-axis direction. After two clamping assemblies move in opposite directions, the clamping piece 22 can be abutted against the surface of the battery module, so that the battery module is clamped, and each surface is abutted against at least two clamping pieces 22, so that the clamping stability can be improved.

Preferably, among the plurality of clip members 22 connected to the same clip member holder 21, at least one clip member 22 is position-adjustably mounted to the clip member holder 21 in the Y-axis direction. For a plurality of battery modules having different sizes in the Y-axis direction (in this embodiment, the size is referred to as the length of the battery module), the clamping requirements of the plurality of battery modules having different lengths can be satisfied by adjusting the distance between the two clamping members 22 mounted to the same clamping member fixing member 21.

As shown in fig. 3, in this embodiment, the clamping member 22 is provided with a plugging portion, and the plugging portion can be plugged into a hoisting hole reserved for the battery module, so that the hoisting accuracy and stability of the battery module can be improved, and the hoisting efficiency can be improved.

Specifically, the first connecting member 13 is provided with a holder 16, and the guide shaft 15 passes through the holder 16 and the first connecting member 13 in the Z-axis direction and is interference fit with the holder 16 to be fixed. The lower extreme of guiding axle 15 is connected with second connecting piece 14, and second connecting piece 14 extends along the Y axle direction setting, and Z axle locating part 51 is connected in second connecting piece 14 along Y axle direction position adjustable. For battery modules with different dimensions along the Z-axis direction (in this embodiment, the dimensions are referred to as the heights of the battery modules), the distance between the Z-axis limiting member 51 and the plugging portion can be adjusted by loosening the clamping seat 16 and adjusting the fixed height of the guide shaft 15, so as to meet the limiting requirements of the battery modules with different heights.

Further, as shown in fig. 3, the hoisting fixture further includes a Y-axis limiting member 52, the two Y-axis limiting members 52 are adjustably connected to the second connecting member 14 along the Y-axis direction, the Y-axis limiting member 52 can be in limiting abutment with the end of the battery module along the Y-axis direction, and the battery module is limited between the two Y-axis limiting members 52, so that the battery module is prevented from shaking along the Y-axis direction, and the stability of the battery module during clamping and hoisting is further improved.

Specifically, in the present embodiment, the second connecting member 14 is provided with a plurality of screw holes aligned in the Y-axis direction, and the Z-axis stopper 51 and the Y-axis stopper 52 are each provided with a stopper groove, and the fastening bolts pass through the stopper grooves to be fixed to the screw holes of the second connecting member 14, thereby detachably connecting the Z-axis stopper 51 and the Y-axis stopper 52 with the second connecting member 14.
