Description
Technical Field
[0001] The utility model relates to the technical field of logistics and transportation, in particular to an electric blocking clamp. Background Art
[0002] The electric blocking clamp is a device driven by electricity, mainly used for clamping and fixing objects. In practical applications, the electric blocking clamp is widely used in industrial production, logistics handling and other scenarios, providing stable, efficient and safe clamping and fixing solutions for various objects. The electric blocking clamp is suitable for blocking and clamping moving carriers, skids, pallets, etc. to achieve the functional needs of stopping or positioning.
[0003] During use, the existing electric blocking clamp usually clamps the object by moving two sets of clamping blocks horizontally. However, the above method can only clamp square objects. When clamping objects with arcs or curves, the objects may fall off, affecting the clamping and conveying effect of the objects.
[0004] Therefore, it is necessary to provide a new electric blocking clamp to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of the utility model is to provide an electric blocking clamp to solve the problems raised in the above background technology.
[0006] To achieve the above purpose, the utility model provides the following technical solution: an electric blocking clamp, comprising a base, and also comprising:
[0007] A motor is installed on the top of the base and is arranged horizontally, wherein the output end of the motor is fixedly connected to a driving shaft, and one side of the driving shaft is fixedly connected to an eccentric swing rod arranged horizontally;
[0008] A support seat is fixed on the top of the base, and the inner cavity of the support seat is rotatably connected to two sets of fixed shafts through a rotating shaft. The outer sides of the fixed shafts are respectively fixedly connected to the front clamping arm and the rear clamping arm, and the front clamping arm and the rear clamping arm are used in coordination.
[0009] Preferably, the tops of the front clamping arm and the rear clamping arm are both fixedly connected with clamping blocks, and the clamping blocks are arranged in a square shape.
[0010] Preferably, a slide groove is provided inside the front clamping arm and the rear clamping arm, and the inner wall of the slide groove is slidably connected to the outer side of the eccentric swing rod.
[0011] Preferably, a roller is provided on the outer side of the eccentric swing arm, and the roller is used in conjunction with the front clamping arm and the rear clamping arm.
[0012] Preferably, mounting bolts are provided inside the clamping block, and the clamping block is fixed to the front clamping arm and the rear clamping arm by the mounting bolts.
[0013] Preferably, one side of the rear clamping arm is fixedly connected to a limiting rod, and one end of the limiting rod is fixedly connected to a clamping rod.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The utility model drives the driving shaft to rotate through a motor, so that the eccentric swing rod rotates. In the low position state, the front clamping arm and the rear clamping arm are open. In the clamping process, because the swing rod that drives the clamping arm to rotate is eccentric, the front clamping arm will be lifted faster than the rear clamping arm to become a one-way block. As the clamping arm continues to be lifted, the rear clamping arm will catch up with the front clamping arm to form a closed clamping state in the high position, so that objects with curvature can be clamped.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4As shown, an electric blocking clamp comprises a base 1, a motor 2 installed on the top of the base 1 and arranged horizontally, the motor 2 is the power source of the device, the output end of the motor 2 is fixedly connected with a driving shaft 3, one side of the driving shaft 3 is fixedly connected with a horizontally arranged eccentric swing rod 4, the eccentric swing rod 4 is fixed at the bottom position of one side of the driving shaft 3, the motor 2 drives the driving shaft 3 to rotate, so that the eccentric swing rod 4 rotates, and a support seat 5 fixed to the top of the base 1, the inner cavity of the support seat 5 is rotatably connected with two groups of fixed shafts 6 through a rotating shaft, and the outer sides of the fixed shaft 6 are respectively fixedly connected with a front clamping arm 7 and a rear clamping arm 8, the front clamping arm 7 and the rear clamping arm 8 are used together, in the low position, the front clamping arm 7 and the rear clamping arm 8 are open, in the clamping process, because the swing rod driving the clamping arm to rotate is eccentric, the front clamping arm 7 will be lifted faster than the rear clamping arm 8 to become a one-way blocking, as the clamping arm continues to lift, the rear clamping arm 8 will catch up with the front clamping arm 7 to form a closed clamping state at a high position, this lifting and blocking opening and closing process is a fully mechanical structure, which is simple and reliable.
[0023] refer to Figure 3 and Figure 4 As shown, the tops of the front clamping arm 7 and the rear clamping arm 8 are fixedly connected with clamping blocks 9, and the clamping blocks 9 are set to be square. When the front clamping arm 7 and the rear clamping arm 8 are closed, the two groups of clamping blocks 9 will be driven to move, so that the clamping blocks 9 clamp the objects. The interiors of the front clamping arm 7 and the rear clamping arm 8 are provided with sliding grooves 10, and the inner walls of the sliding grooves 10 are slidingly connected with the outer sides of the eccentric swing rod 4. The outer sides of the eccentric swing rod 4 are provided with rollers 11, and the rollers 11 are used in conjunction with the front clamping arm 7 and the rear clamping arm 8. The eccentric swing rod 4 drives the rollers 11 to roll in the sliding grooves 10 to generate a lifting torque, which finally causes the front clamping arm 7 and the rear clamping arm 8 to form a lifting opening and closing movement.
[0024] refer to Figure 4 As shown, a mounting bolt 12 is provided inside the clamp block 9, and the clamp block 9 is fixed to the front clamp arm 7 and the rear clamp arm 8 by the mounting bolt 12. A limiting rod 13 is fixedly connected to one side of the rear clamp arm 8, and a clamping rod 14 is fixedly connected to one end of the limiting rod 13. The limiting rod 13 and the clamping rod 14 can be inserted into the interior of the object to be clamped to limit the object.
[0025] Working principle: When the device is in use, the motor 2 drives the drive shaft 3 to rotate, so that the eccentric swing rod 4 rotates. In the low position, the front clamping arm 7 and the rear clamping arm 8 are open. During the clamping process, because the swing rod that drives the clamping arm to rotate is eccentric, the front clamping arm 7 will be lifted faster than the rear clamping arm 8, thus becoming a one-way block. As the clamping arm continues to lift, the rear clamping arm 8 will catch up with the front clamping arm 7, thus forming a closed clamping state at a high position. This lifting, blocking, opening and closing process is a fully mechanical structure, which is simple and reliable. The eccentric swing rod 4 drives the roller 11 to roll in the slide groove 10 to generate a lifting torque, which eventually causes the front clamping arm 7 and the rear clamping arm 8 to form a lifting, opening and closing movement. When the front clamping arm 7 and the rear clamping arm 8 are closed, they will drive the two sets of clamping blocks 9 to move, so that the clamping blocks 9 clamp the objects. The clamping blocks 9 are fixed to the front clamping arm 7 and the rear clamping arm 8 by installing bolts 12.
