Description

Technical Field

[0001] The utility model belongs to the technical field of power battery disassembly, and particularly relates to a power battery side plate traction clamp. Background Art

[0002] New energy batteries are mainly lithium iron phosphate batteries with stable performance. They are wrapped in aluminum shells and made into block structures with a length, width and thickness of about 15*12*3cm. As a power battery component, the battery pack is assembled by splicing multiple battery cells. The battery cells are glued together and then supported by a frame on the outside. When the power battery pack reaches the end of its service life, it still has a high recycling value.

[0003] In the premise stage of recycling battery cells, the power battery pack needs to be disassembled. First, the frame structure is cut off by a cutting device. After removing the frame, the internal battery pack is composed of multiple battery cells arranged in rows, and the battery cells are fixed by glue. The side of the battery pack also has an epoxy board and a terminal board. The terminal board connects each battery block in series, and the corresponding positive and negative poles of the battery are fixed by soldering. The epoxy board is used for side insulation to prevent leakage of the outer shell. At the same time, it is installed in the protective shell to play a good buffering and anti-collision role. Both are fixed to the side of the battery pack by bonding. When separating the battery blocks, the terminal board and the epoxy board need to be separated. The manual separation method is very inefficient. The existing separation is performed mechanically, with a designed guiding traction device, a clamp, and a fixing device. The battery pack is fixed to the fixing device, and the clamp clamps the side panel. Then the traction device drives the clamp to drag, and the side panel is separated when the external force drops.

[0004] The utility model mainly improves the clamping function of the clamp, processes the front end of the ordinary clamp into a cone, is conducive to insertion along the gap between the side plate and the battery block, and then clamps and fixes, increases the clamping surface of the clamp, and has higher disassembly efficiency.

[0008] The lower jaw part has a protruding conical part, which is integrally arranged with the lower jaw part and has an inwardly concave arc transition surface corresponding to the lower side. The upper jaw part and the lower jaw part overlap on the corresponding clamping sides and are both provided with coarse teeth meshing with each other, and the conical part has fine teeth.

[0009] Furthermore, the concave arc transition surface corresponding to the lower side of the lower jaw portion has an arc edge, and the arc edge is fixed integrally with the lower jaw portion. A sleeve is fixed to the tail of the movable handle, and a traction rod is sleeved in the sleeve and rotated to cooperate, and the end of the traction rod is a limit block for cooperating with the end of the sleeve to limit.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figure 1-3 As shown: a power battery side plate traction clamp comprises an upper jaw part 1 and a lower jaw part 2, wherein the rear end of the upper jaw part 1 is a fixed handle 3, and the rear end of the lower jaw part 2 is hinged to a movable handle 4, and the rear side of the lower jaw part 2 has a first hinge seat 22 and a second hinge seat 23 arranged up and down, and the lower jaw part 2 is hinged to the fixed handle through the first hinge seat 22, so that the lower jaw part 2 is flipped and cooperates with the upper jaw part 1 to complete the clamping operation, and the second hinge seat 23 is hinged to the end of the movable handle 4, and a connecting rod 5 is also installed between the fixed handle 3 and the movable handle 4; the movable handle is flip-mounted with the lower jaw part through the second hinge seat, and is moved toward the fixed handle by pressing the movable handle, and a lever principle is formed through the corresponding hinge positions of the first hinge seat and the second hinge seat, so that the upper jaw part and the lower jaw part complete the clamping, wherein the connecting rod acts as a fulcrum.

[0019] The lower jaw part 2 has a protruding conical portion 21, which extends along the length direction of the lower jaw part. The conical portion 21 is integrally arranged with the lower jaw part 2, and the corresponding lower side is an inwardly concave arc transition surface. The corresponding clamping sides of the upper jaw part 1 and the lower jaw part 2 overlap, and both are provided with coarse teeth that mesh with each other, and the conical portion 21 has fine teeth.

[0020] The side panel includes an epoxy panel and a terminal board. During operation, since the battery pack side panel is bonded and fixed to the side of the battery pack, the gap between the side panel and the battery pack is very small. The tapered portion can be inserted into the gap first, and then the gap is initially separated under the action of the transition surface to expand the gap, so that the corresponding clamp can lock the side of the side panel, and the movable handle is driven to make the clamp clamp to complete the clamping effect on the side wall. The traction is completed by the traction device at the tail end of the clamp, thereby realizing the separation of the side panel.

[0021] The structure composed of the tapered part and the lower clamp part is similar to an eagle's beak structure, and at the same time the overlap surface with the side plate is increased to improve the clamping stability.

[0022] like Figure 1As shown: the concave arc transition surface corresponding to the lower side of the lower jaw 2 has an arc ridge 24, and the arc ridge 24 is fixed integrally with the lower jaw 2. There are two arc ridges, which are used to improve the force strength of the arc part, and at the same time, they are used to replace the arc surface to contact the side of the side plate to reduce friction resistance. A sleeve 41 is fixed at the tail of the movable handle 4, and a traction rod 7 is sleeved in the sleeve 41 and rotated to cooperate. The end of the traction rod 7 is a limit block 71, which is used to cooperate with the end of the sleeve 41 for limiting. The traction rod is used to drag the entire clamp. Under the action of the sleeve rotating cooperation, the clamping direction of the clamp can be adjusted to facilitate the clamping and fixing of the horizontal fixed side and the longitudinal fixed side plate. One end of the connecting rod 5 is hingedly installed with the movable handle 4, and the other free end is slidably installed on the fixed handle 3. The tail of the fixed handle 3 has a threaded sleeve 31, and a rotating rod is threadedly sleeved, and the free end of the connecting rod 5 is locked by the rotating rod. Press the movable handle to make the free end of the connecting rod slide in the inner groove of the fixed handle. After the clamping is completed, the connecting rod is locked by the end of the rotating rod against the free end of the connecting rod, so that the clamping side corresponding to the clamp is locked to complete the clamping and fixation. To release the clamping effect, the rotating rod can be rotated to release the lock.

[0023] A connecting ear is provided between the first hinge seat 22 and the second hinge seat 23, and a tension spring 6 is connected to the middle position of the connecting ear and the fixed handle 3. When the rotary rod is released and locked, the tension spring can automatically contract to release the clamping side of the clamp.

[0024] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
