Description

Technical Field

[0001] The utility model relates to the technical field of plastic carving processing, in particular to a fixing clamp used for plastic carving processing. Background Art

[0002] In the field of plastic engraving processing, fixing fixtures are indispensable tools. Most of the existing fixing fixtures use mechanical clamping or magnetic adsorption to fix plastic sheets. Although these methods can fix the sheets to a certain extent, there are still some problems in the actual processing process. For example, the mechanical clamping method may scratch the surface of the sheet due to improper operation, and the magnetic adsorption method is limited by the material and thickness of the sheet, and the adsorption force may not be stable enough, resulting in vibration or displacement during the processing. Therefore, it is necessary to develop a new type of fixing fixture to improve the processing stability and finished product quality of plastic sheets. Utility Model Content

[0003] The purpose of the utility model is to provide a fixing fixture for plastic engraving processing to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing fixture for plastic engraving processing, comprising a main frame, an adsorption assembly and a clamping assembly, an adjustment hole is opened inside the main frame, four groups of clamping assemblies are arranged on the top of the main frame, the clamping assembly comprises a fixing screw, a sleeve seat, an elastic member and a clamping plate, a sleeve seat is installed on the outside of the fixing screw, an elastic member is installed on one side of the sleeve seat, a clamping plate is installed on one side of the elastic member, an adsorption assembly is installed on the bottom of the main frame by bolts, and the adsorption assembly comprises a base frame, a cylinder, a suction cup and an air pipe.

[0005] When in use, place the plastic sheet to be fixed on the main frame, adjust the installation position of the clamping assembly on the main frame, the elastic part has a certain elasticity during the clamping process, effectively prevents deformation of the plastic material, and realizes fixed clamping of the plastic material. At the same time, the operation of the cylinder causes the suction cup to generate negative pressure. The negative pressure adsorption generated by the suction cup can firmly fix plastic sheets of different materials and thicknesses, and effectively prevent vibration and displacement during processing. The suction cup is made of highly elastic material and can adapt to the surfaces of plastic sheets of different shapes, thereby improving the versatility of the clamp. Moreover, since the suction cup is made of flexible material, it can effectively avoid scratches on the surface of the sheet, thereby ensuring the quality of the finished product. The device uses negative pressure adsorption and fixed clamping to ensure processing stability.

[0006] Preferably, four cylinders are installed at the bottom of the base frame, suction cups are installed at the tops of the cylinders, and air pipes are installed at the bottoms of the cylinders.

[0007] The air pipe can be connected to an external vacuum pump. When the inside of the cylinder is in a vacuum, the suction cup generates suction on the bottom of the plate.

[0008] Preferably, the fixing screw penetrates the inside of the adjusting hole and is fixed to the adjusting hole by a bolt.

[0009] The position of the fixing screw inside the adjusting hole can be adjusted by removing the bolt to adapt to plastic materials of different sizes.

[0010] Preferably, two sets of mounting feet are fixedly mounted on both sides of the main frame.

[0011] The main frame can be stably installed in the designated position by using the mounting feet in conjunction with the external bolts.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] When the utility model is in use, the plastic sheet to be fixed is placed on the main frame, and the installation position of the clamping component on the main frame is adjusted. During the clamping process, the elastic member has a certain elasticity, which effectively prevents the plastic material from being deformed. The negative pressure adsorption generated by the suction cup can firmly fix the plastic sheets of different materials and thicknesses, and effectively prevent vibration and displacement during the processing. Moreover, since the suction cup is made of flexible material, it can effectively avoid scratches on the surface of the sheet, thereby ensuring the quality of the finished product. The device adopts the coordinated use of negative pressure adsorption and fixed clamping to ensure processing stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the utility model proposes a fixing fixture for plastic engraving processing, including a main frame 1, an adsorption component 2 and a clamping component 3. An adjustment hole 102 is opened inside the main frame 1, and four groups of clamping components 3 are arranged on the top of the main frame 1. The clamping component 3 includes a fixed screw 301, a sleeve seat 302, an elastic member 303 and a clamping plate 304. The sleeve seat 302 is installed on the outside of the fixed screw 301, the elastic member 303 is installed on one side of the sleeve seat 302, and the clamping plate 304 is installed on one side of the elastic member 303. The adsorption component 2 is installed on the bottom of the main frame 1 by bolts, and the adsorption component 2 includes a base frame 201, a cylinder 202, a suction cup 203 and an air pipe 204.

[0032] The working principle of the fixing fixture for plastic engraving processing based on the first embodiment is: when in use, the plastic sheet to be fixed is placed on the main frame 1, and the installation position of the clamping component 3 on the main frame 1 is adjusted. During the clamping process, the elastic member 303 has a certain elasticity, which effectively prevents the plastic material from deforming and realizes the fixed clamping of the plastic material. At the same time, the operation of the cylinder 202 causes the suction cup 203 to generate negative pressure. The negative pressure adsorption generated by the suction cup 203 can firmly fix plastic sheets of different materials and thicknesses, and effectively prevent vibration and displacement during the processing. The suction cup 203 is made of highly elastic material and can adapt to the surface of plastic sheets of different shapes, thereby improving the versatility of the fixture. Moreover, since the suction cup 203 is made of flexible material, it can effectively prevent the surface of the sheet from being scratched, thereby ensuring the quality of the finished product. The device adopts the coordinated use of negative pressure adsorption and fixed clamping to ensure processing stability.

[0035] In this embodiment, Figure 3 As shown, the air pipe 204 can be connected to an external vacuum pump. When the interior of the air cylinder 202 is in a vacuum, the suction cup 203 generates suction on the bottom of the plate; Figure 4 As shown, the position of the fixing screw 301 inside the adjustment hole 102 can be adjusted by removing the bolt to adapt to plastic materials of different sizes; Figure 1 As shown, the main frame 1 can be stably installed at a specified position by using the mounting feet 101 in conjunction with the external bolts.
