[0021] Schematic diagram.
[0022] As attached Figure 1 As shown, an in-mold pre-embedded nut clamp includes a base 1, a push rod 2, a push rod linear drive mechanism 3, a tube body 4, and an elastic gripper 5. The push rod linear drive mechanism 3 is installed on the base 1. The push rod 2 for opening the elastic gripper 5 is connected to the moving part of the push rod linear drive mechanism 3. The tube body 4 is connected to the base 1. The tube body 4 has grooves on both sides for passing through the head end of the elastic gripper 5. The tail end of the elastic gripper 5 is connected to the tube body 4. The end of the push rod 2 is placed inside the tube body 4.
[0023] As attached Figure 2 As shown, the elastic gripper 5 is fitted with an elastic ring 6 to increase the gripping force of the elastic gripper 5.
[0024] The elasticity of the elastic ring 6 can increase the closing clamping force of the two elastic jaws 5, thereby improving the stability of clamping the nut.
[0025] The tail ends of the two elastic clamping jaws 5 are respectively arranged on the opposite sides of the connecting ring 7, the pipe body 4 passes through the connecting ring 7, and the connecting ring 7 is fixedly connected with the pipe body 4 through bolts. The connecting ring 7 and the elastic clamping jaws 5 are detachably connected on the pipe body 4, so that replacement and maintenance are facilitated.
[0026] The push rod linear driving mechanism 3 is a single-rod cylinder.
[0027] The cylinder body of the push rod linear driving mechanism 3 is fixed on the base 1, the piston rod of the push rod linear driving mechanism 3 is connected on the moving plate 8, and the moving plate 8 is in sliding fit connection with the base 1.
[0028] The piston rod of the push rod linear driving mechanism 3 is retractable, so as to drive the moving plate 8 and the push rod 2 to move linearly back and forth.
[0029] A plurality of push rods 2 are vertically connected on the moving plate 8, a plurality of pipe bodies 4 are connected on the base 1, and the plurality of push rods 2 correspond to the plurality of pipe bodies 4 respectively.
[0030] A plurality of guide rods 9 are fixed on the base 1.
[0031] A plurality of guide pipes 10 are fixed on the base 1. The guide rods 9 are inserted into the guide pipes on the nut carrier in alignment, and the guide pipes 10 are sleeved on the guide rods on the nut carrier, so that the pipe bodies 4 can be precisely connected to the nuts on the nut carrier.
[0032] The working mode of the present application is as follows: before the clamp clamps the nut, the end of the push rod 2 is located between the two elastic clamping jaws 5, so that the two elastic clamping jaws 5 are in an open state. Then the multi-axis robot drives the clamp to move to the nut carrier, so that the nut is inserted into the pipe body 4. Then the push rod linear driving mechanism 3 drives the push rod 2 to move backward, and after the elastic clamping jaws 5 are separated from the interference of the push rod, the elastic clamping jaws 5 restore deformation and clamp the nut by using the elastic force. After the pipe body 4 is moved into the injection molding machine, the push rod 2 moves towards the nut, and after the two elastic clamping jaws 5 are opened, the nut is finally pushed out of the pipe body 4 and placed in the injection molding machine.
[0033] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of claims.
