Description

Technical Field

[0001] This utility model relates to the field of clamping and pressing components, and more specifically, to a clamping and pressing component for processing plastic materials. Background Technology

[0002] Plastic materials are materials that can undergo significant and permanent plastic deformation under external forces (the deformation does not recover after unloading) and have a large deformation capacity before fracture. They are distinct from "brittle materials". Plastic materials cover multiple fields such as metals, polymers, and composite materials. Common examples include: metals: low carbon steel, aluminum alloys, copper alloys, titanium alloys, etc. (most commonly used in industrial processing); polymers: plastics (such as PP, ABS, PVC), rubber, resins; composite materials: fiber reinforced plastics (FRP), carbon fiber composites (CFRP), etc.

[0003] Plastic materials have low rigidity, and if they are not firmly clamped during processing, they are prone to resonance or relative displacement with the cutting tool. Therefore, a clamping and pressing component for processing plastic materials is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a clamping and pressing assembly for processing plastic materials, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a clamping and pressing assembly for processing plastic materials, including a limiting cylinder, a support column is provided on the top of the limiting cylinder, an installation groove is provided on the support column, a limiting shaft is embedded in the installation groove, a first clamping plate and a second clamping plate are rotatably connected to the limiting shaft, the first clamping plate and the second clamping plate are arranged opposite to each other, and clamping blocks are rotatably connected to their top ends respectively, and an anti-slip pad is provided on one side of each clamping block.

[0006] Optionally, in one possible implementation, connecting blocks are fixedly provided on opposite sides of the first clamping plate and the second clamping plate, each connecting block is sleeved on the limiting shaft and rotatably connected to the limiting shaft, and two connecting blocks are staggered to form a triangular groove between them, and a crossbar is provided in the triangular groove. An electric push rod is provided inside the limiting cylinder, and the output end of the electric push rod is connected to the crossbar to drive the crossbar to move up and down. The bottom of the mounting groove is provided with a limit spring, and the top of the limit spring is connected to the bottom of the first clamping plate and the second clamping plate respectively. Optionally, in one possible implementation, the top ends of the first clamping plate and the second clamping plate are respectively provided with sliding grooves, and each clamping block is slidably connected to the corresponding clamping plate through the sliding grooves. The anti-slip pad can be made of rubber or polyurethane material, and the bottom of the limiting cylinder is provided with a mounting flange for fixed connection with the workbench.

[0007] The technical effects and advantages of this utility model are as follows: The electric push rod drives the crossbar to move up and down, and the staggered connecting blocks drive the first clamping plate and the second clamping plate to rotate around the limiting axis. This can achieve precise clamping of plastic materials of different sizes and avoid resonance or relative displacement problems caused by loose clamping during processing. Meanwhile, the clamping block is slidably connected to the clamping plate through the slide groove and can rotate around its connection point, which can fit the surface of irregularly shaped workpieces such as arcs and irregular shapes. When combined with anti-slip pads made of rubber or polyurethane, the friction with the workpiece is further increased, providing double protection for clamping stability and making it suitable for various plastic material processing scenarios.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This embodiment discloses a clamping and pressing assembly for processing plastic materials, which is used to stably clamp the plastic material during the processing to prevent the processing accuracy from being affected by vibration or displacement. The specific settings are as follows.

[0016] like Figures 1 to 4 As shown, the clamping and pressing assembly includes a limiting cylinder 1, with a support column 2 fixedly mounted on its top. The support column 2 has an installation groove 3, and a limiting shaft 4 is embedded within the installation groove 3. A first clamping plate 5 and a second clamping plate 6 are rotatably connected to the limiting shaft 4, and the two are arranged opposite each other to form a clamping space.

[0017] like Figure 4 As shown, connecting blocks 7 are fixedly installed on opposite sides of the first clamping plate 5 and the second clamping plate 6, respectively. The connecting blocks 7 are sleeved on the limiting shaft 4 and can rotate around it. The two connecting blocks 7 are arranged alternately to form a triangular groove, and a crossbar 12 is installed in the triangular groove.

[0018] like Figure 2 and Figure 3 As shown, the limiting cylinder 1 is equipped with an electric push rod 11, the output end of which is connected to the crossbar 12. When the electric push rod 11 is started, it can push the crossbar 12 to move up and down, which in turn drives the first clamping plate 5 and the second clamping plate 6 to rotate around the limiting shaft 4 through the connecting block 7, thereby realizing the clamping or loosening action.

[0019] like Figure 2 As shown, a limit spring 10 is provided at the bottom of the mounting groove 3, and its top end is connected to the bottom of the first clamping plate 5 and the second clamping plate 6 respectively. The limit spring 10 is used to provide a restoring force when the clamping plates are released, ensuring that the clamping plates quickly return to their original position.

[0020] like Figure 4 As shown, the top ends of the first clamping plate 5 and the second clamping plate 6 are respectively provided with sliding grooves 13. The clamping block 8 is slidably connected to the clamping plate through the sliding grooves 13 and can rotate around the connection point to adapt to the surface of workpieces of different shapes. An anti-slip pad 9 is glued to one side of the clamping block 8. The anti-slip pad 9 is made of rubber material and is used to increase friction and prevent the workpiece from slipping. The specific working principle is as follows: when no clamping operation is performed, the electric push rod 11 inside the limiting cylinder 1 is in a retracted state, and the crossbar 12 is in a lower position. At this time, the limiting spring 10 at the bottom of the mounting groove 3 is in a naturally extended state. The first clamping plate 5 and the second clamping plate 6 are kept in an open state under the support of the limiting spring 10. A large placement space is formed between the clamping blocks 8 at the top of the two clamping plates, which makes it convenient for the operator to put the plastic material to be processed into the clamping area.

[0021] When clamping the plastic material is required, the electric push rod 11 is activated, and its output end extends upward, pushing the connected crossbar 12 to move vertically. Since the crossbar 12 is located within the triangular groove formed by two staggered connecting blocks 7, its upward movement exerts an inward pushing force on the two connecting blocks 7. Because the connecting blocks 7 are fixed to opposite sides of the first clamping plate 5 and the second clamping plate 6, and are rotatably connected to the limiting shaft 4, the first clamping plate 5 and the second clamping plate 6 rotate synchronously inward around the limiting shaft 4 under the pushing force. As the clamping plates rotate, the clamping block 8 at their top gradually approaches the plastic material to be processed, until the anti-slip pad 9 on the clamping block 8 is tightly fitted against the workpiece surface. At this point, the electric push rod 11 stops, completing the clamping operation of the plastic material, and subsequent processing steps can begin.

[0022] After the plastic material is processed, the electric push rod 11 retracts, and its output end drives the crossbar 12 to move downwards in the vertical direction, eliminating the pushing force of the crossbar 12 on the connecting block 7. At this time, the limiting spring 10 at the bottom of the mounting groove 3 releases its elasticity, generating an upward pushing force on the bottom of the first clamping plate 5 and the second clamping plate 6 respectively, pushing the first clamping plate 5 and the second clamping plate 6 to rotate outwards around the limiting shaft 4, gradually returning to the open state. At the same time, the clamping block 8 separates from the workpiece surface as the clamping plates rotate, thus releasing the workpiece. After the electric push rod 11 is fully retracted and the crossbar 12 returns to its initial low position, the clamping plates remain stably in the open state under the action of the limiting spring 10, and the operator can then remove the processed workpiece, and the assembly awaits the next clamping cycle.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
