Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of computers and automation, and particularly relates to a clamping claw mechanism. Background Art
[0002] In the current hot pressing method of hot composite core stacking, the base of the hot pressing table is not a complete plane, and a lifting platform is installed on the base of the hot pressing table. When the clamp transfers the core stack from the stacking table to the hot pressing table, the lifting platform rises, the clamp places the core stack on the lifting platform, and the lifting platform falls and is on the same horizontal plane as the hot pressing table. Because the gap and height difference between the lifting platform and the hot pressing table cannot be completely eliminated, the embossing on the core stack cannot be completely avoided after the core stack is heated and pressurized on the hot pressing table. Utility Model Content
[0003] The technical problem to be solved by the utility model is that a clamping claw mechanism is proposed, and the way of conveying the stacked cores to the hot pressing table is changed to horizontal pushing, so that the hot pressing table forms a complete horizontal plane, thereby eliminating embossing.
[0004] The utility model adopts the following technical solutions to solve the above technical problems:

[0008] The cylinder is used to provide a driving force in the horizontal direction, so that the pressed objects are evenly stressed, and combined with the clamping jaws and the cylinder, the pressed objects can be pushed accurately; the use of the clamping jaws improves efficiency.
[0009] Furthermore, an upper pin and a lower pin are symmetrically arranged on the baffle plate with the center of the baffle plate as the center, and the upper pin is directly above the lower pin.
[0010] The opposite surfaces of the upper and lower clamping jaws are both provided with grooves, and the upper and lower pins are arranged in the corresponding grooves.
[0011] Furthermore, the width of the groove is one third of the width of the clamping jaw, and the depth is one half of the depth of the clamping jaw.

[0013] Furthermore, the distance between the two pins is in the range of one half to two thirds of the length of the stacked core.
[0014] Furthermore, the baffle length is greater than the core stack length.
[0015] Furthermore, the mechanism also includes a pad block, which is fixedly arranged on the inner surface of the upper clamping jaw, and the inner surface of the upper clamping jaw corresponds to the lower clamping jaw.
[0016] Furthermore, the pads are fixed on both sides of the groove on the inner surface of the upper clamping jaw by screws.
[0017] The utility model adopts the above technical solution, and compared with the prior art, its significant technical effects are as follows:
[0018] 1. The utility model can accurately control the position of the object on the press table through the stroke of the clamping claw and the cylinder.
[0019] 2. The clamping mechanism proposed by the utility model replaces the manual placement method, thereby improving safety and efficiency.
[0020] 3. The utility model cancels the lifting structure on the press table base and replaces it with horizontal pushing.

[0022] Figure 2 It is a structural diagram of the baffle of the utility model. DETAILED DESCRIPTION
[0023] In order to enable technicians to better understand the method of the utility model, the technical solution in the embodiment of the utility model will be described in detail below in conjunction with the drawings in the example of the utility model.
[0024] To achieve the above purpose, the utility model provides a clamping claw mechanism, such as Figure 1 As shown, including:
[0025] Cylinder, clamp and baffle. The clamp includes an upper clamp and a lower clamp, the upper clamp is located directly above the lower clamp; the baffle is placed in the middle of the upper and lower clamps, and the baffle is slidably connected with the upper and lower clamps; the cylinder is located at the center of the baffle, and the cylinder is used to provide a driving force in the horizontal direction. The cylinder is selected to have a small cylinder diameter and a large stroke, so as to avoid interference with other structures and be compatible with more sizes of stacked cores.
[0026] The upper pin and the lower pin are symmetrically arranged on the baffle with the center of the baffle as the center, and the upper pin is directly above the lower pin; the opposite surfaces of the upper and lower clamping jaws are provided with grooves, and the upper and lower pins are arranged in the corresponding grooves.
[0027] The width of the groove is one third of the width of the jaw and the depth is one half of the depth of the jaw.
[0028] like Figure 2 As shown, the mechanism includes two clamping jaws; two upper pins and lower pins are arranged on the baffle plate, and the two upper pins are arranged symmetrically with the center of the baffle plate as the center, and the two lower pins are arranged symmetrically with the center of the baffle plate as the center. The lower clamping jaw is fixed, and the groove of the lower clamping jaw is embedded in the lower pin; the baffle plate is limited by the grooves of the two lower clamping jaws and the push rod of the cylinder. When the clamping jaws are clamped, the upper pin of the block can be embedded in the groove of the upper clamping jaw.
[0029] The distance between the two pins is in the range of one-half to two-thirds of the length of the stacked core.
[0030] The baffle length is greater than the core stack length.
[0031] The mechanism also includes a cushion block, which is fixedly arranged on the inner surface of the upper clamping jaw, and the inner surface of the upper clamping jaw corresponds to the lower clamping jaw.
[0032] The pads are fixed by screws on both sides of the groove on the inner surface of the upper clamp. The pads avoid the sliding area of the groove and the upper pin, and the length of the pads should be longer than the width of the stacked core. Different pads are replaced according to the height matching different stacked core thicknesses (the height of the clamp against the upper pin - the thickness of the stacked core ≤ the height of the pad).
[0033] The novel core stacking clamp mechanism of the present invention is used to realize horizontal transfer of the core stack to the hot pressing table, and the specific steps are as follows:
[0034] S1. After the core stack is stacked, the upper clamp opens and the clamp moves so that the core stack is located between the upper and lower clamps.
[0035] S2. Lift the jaws slightly and place the stacked core on the lower jaws.
[0036] S3. The upper clamp presses down to clamp the stacked core, and the lower clamp and the cushion block fit the surface of the stacked core.
[0037] S4. The clamping jaws move with the stacked core to the outside of the hot pressing table, and the top surface of the lower clamping jaws is parallel to or slightly higher than the end surface of the hot pressing table.
[0038] S5. The upper clamp opens, the cylinder pushes the baffle, and the baffle pushes the stacked core to move toward the end surface of the hot pressing table.
[0039] S6. After the clamps are moved away, the hot press table heats and presses the stacked cores.
[0040] S7. After the hot pressing is completed, the clamping jaws are moved back to the hot pressing table, and the top surface of the lower clamping jaws is parallel to or slightly lower than the end surface of the hot pressing table.
[0041] S8. A cylinder and baffle on the inner side of the hot press table push the stacked core back to the clamping jaws.
[0042] S9, the upper clamp clamps the core for transfer.
[0043] The utility model eliminates the lifting platform structure of the hot pressing platform, and the end surface of the hot pressing platform is a complete plane. Therefore, there is no more stamping after the core stacking is hot pressed, thereby improving the quality of the battery core stacking.
[0044] The above embodiments are only for illustrating the technical idea of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
