Description

Technical Field

[0001] The utility model relates to the technical field of acrylic polymerization auxiliary, in particular to an acrylic polymerization auxiliary tooling. Background Art

[0002] Acrylic, also known as polymethyl methacrylate (PMMA), is a transparent plastic material with the advantages of low price, easy processing and molding, high strength and light weight. It is widely used in aerospace, building materials, optical instruments and other fields. In the application industry, the raw materials of acrylic generally appear in the form of particles, plates, pipes, etc. When two acrylic plates need to be spliced, the splicing material will be poured into the splicing seam between the two and wait for the polymer to polymerize and solidify. However, the splicing material poured into the splicing seam will shrink during the curing process, causing the splicing seam to be short of material, bubbles, etc., which requires reprocessing, which is time-consuming and labor-intensive. Therefore, it is urgent to design a tool that can help exhaust the air in the splicing seam to reduce the generation of bubbles or prevent the situation of short of material. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects in the prior art that the splicing material between two acrylic plates shrinks during the polymerization and curing process, thereby causing material shortages, bubbles and the like in the splicing seams and the processing is time-consuming and labor-intensive, and to provide an acrylic polymerization auxiliary tooling.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an acrylic polymerization auxiliary tooling, including a support frame, the support frame has a longitudinal beam, and first adsorption components for adsorbing the support frame on the surface of an acrylic plate are arranged at both ends of the longitudinal beam, and at least one group of clamping mechanisms are installed on the longitudinal beam between the two first adsorption components. The clamping mechanism includes a telescopic component, a fixed rod installed at the output end of the telescopic component, and a second adsorption component installed on both ends of the fixed rod to adsorb an acrylic block. The fixed rod is in a spatial vertical relationship with the longitudinal beam. The telescopic component has a telescopic rod and a telescopic controller for controlling the descending time and distance of the telescopic rod.

[0005] Furthermore, the distance between adjacent pressing mechanisms is greater than half of the length of the acrylic block and less than the length of the acrylic block. This arrangement helps to distribute the pressure more evenly and avoid fatigue or breakage of the acrylic block caused by local stress concentration.

[0006] Furthermore, the upper end of the telescopic controller is mounted on the longitudinal beam through a sleeve, and the lower end thereof is connected to the telescopic rod, and the lower end of the telescopic rod is connected to the middle of the fixed rod. The upper end of the telescopic controller is provided with a sleeve to facilitate its assembly with the longitudinal beam, and the lower end of the telescopic rod is connected to the middle of the fixed rod, which can ensure that the descending speed and descending distance of the second adsorption components at both ends of the fixed rod remain consistent, which helps to distribute the load more evenly and reduce the pressure on the fixed rod.

[0007] Furthermore, the second adsorption assembly includes a second vacuum suction cup and a mounting frame, wherein the mounting frame is a T-shaped structure, wherein the upper lateral section is a sleeve portion sleeved on the fixing rod, and the lower end of the sleeve portion is connected to the second vacuum suction cup. The T-shaped structure helps to distribute the load more evenly and reduce the pressure on the fixing point. The design of the sleeve allows for position adjustment on the fixing rod to meet different installation requirements.

[0008] Furthermore, the first adsorption assembly at one end of the longitudinal beam includes a first vacuum suction cup, a connecting frame and a second vacuum controller. The connecting frame is L-shaped, one end of which is mounted on the end of the longitudinal beam, and the other end of which is connected to the first vacuum suction cup through a connecting rod. The second vacuum controller is connected to the connecting frame, and is connected to the second vacuum suction cup through a second connecting pipe.

[0009] Furthermore, the first adsorption assembly at the other end of the longitudinal beam includes a first vacuum suction cup, a connecting frame and a first vacuum controller. The connecting frame is L-shaped, one end of which is mounted on the end of the longitudinal beam, and the other end of which is connected to the first vacuum suction cup through a connecting rod. The first vacuum controller is connected to the connecting frame, and is respectively connected to the two first vacuum suction cups through two first connecting pipes.

[0010] The first vacuum controller and the second vacuum controller are respectively arranged at the two ends of the longitudinal beam, which can maintain the stability of the entire tooling. The first vacuum controller controls the two first vacuum suction cups to simultaneously absorb the acrylic plate, and the second vacuum controller controls all the second vacuum suction cups to simultaneously absorb the acrylic block, ensuring stable and effective absorption.

[0011] Furthermore, the longitudinal beam is a hollow tube, the second connecting tube extends into the hollow part of the longitudinal beam and passes through one end to connect with the second vacuum suction cup, and the first connecting tube extends into the hollow part of the longitudinal beam and passes through one end to connect with the first vacuum suction cup. This arrangement reduces the clutter of the distribution of the connecting tubes.

[0012] Furthermore, the support frame also has a plurality of cross beams, and support components are arranged at both ends of the cross beams. Such arrangement ensures the stability of the entire tooling and does not cause shaking due to the external environment.

[0013] Furthermore, the support assembly also includes a telescopic rod and a telescopic controller, the upper end of the telescopic controller is mounted on the crossbeam, the lower end of the telescopic controller is connected to the telescopic rod, the lower end of the telescopic rod is connected to the support column, and the bottom of the support column is provided with a support foot. Such a configuration can expand the scope of application, and can well support curved acrylic plates, etc. The support foot is provided to provide a larger contact area and increase stability.

[0014] Furthermore, the support foot is cylindrical or disc-shaped and made of elastic material. Such a configuration can ensure that vibration can be well absorbed, reduce the impact on the acrylic plate, and can self-adjust according to the unevenness of the support surface to adapt to different support surfaces.

[0015] The beneficial effects of the utility model are as follows: compared with the prior art, the auxiliary tooling of the utility model is an integral whole and is easy to operate. The support frame is fixed on the surface of the acrylic plate through the first adsorption components at both ends of the longitudinal beam of the support frame, and the second adsorption component of the clamping mechanism adsorbs the acrylic blocks that need to be bonded and polymerized. The telescopic component controls the descending time and distance of the telescopic rod through the telescopic controller, thereby controlling the pressing time and pressing distance of the acrylic block. The polymerization is performed while being pressed, thereby ensuring the polymerization effect, and significantly reducing the shortage of materials and bubble phenomena in the polymerization part.

At least one set of clamping mechanisms 5 is installed on the longitudinal beam 31 between the two first adsorption assemblies 4. The number of sets of the clamping mechanisms 5 is actually set according to the length of the acrylic block 2. There is a certain distance between adjacent clamping mechanisms 5. The distance is generally greater than half of the length of the acrylic block 2 and less than the length of the acrylic block 2 itself. Figure 1 and Figure 2 The design of two sets of clamping mechanisms 5 is shown.

[0026] like Figure 3 As shown, the first adsorption assembly 4 at one end of the longitudinal beam 31 includes a first vacuum suction cup 41, a connecting frame 42 and a second vacuum controller 43. The connecting frame 42 is L-shaped, one end of which is sleeved on the end of the longitudinal beam 31, and the other end of which is connected to the first vacuum suction cup 41 through a connecting rod 44. The second vacuum controller 43 is connected to the connecting frame 42, and is connected to all the second vacuum suction cups 531 of the second adsorption assembly 53 through a second connecting pipe 45. Figure 2The first adsorption assembly 4 at the other end of the longitudinal beam 31 includes a first vacuum suction cup 41, a connecting frame 42 and a first vacuum controller 46. The first vacuum controller 46 has the same structure as the second vacuum controller 3, except that the vacuum suction cups they control are different. The first vacuum controller 41 is connected to the two first vacuum suction cups 41 respectively through two first connecting pipes 47.

[0027] The longitudinal beam 31 is a hollow tube, the second connecting tube 45 extends into the hollow part of the longitudinal beam 31 and passes through one end to connect with the second vacuum suction cup 531 , and a first connecting tube 47 extends into the hollow part of the longitudinal beam 31 and passes through one end to connect with the first vacuum suction cup 41 .

[0028] like Figure 4 As shown, the clamping mechanism 5 includes a telescopic component 51, a fixed rod 52 installed at the output end of the telescopic component 51, and a second adsorption component 53 installed at both ends of the fixed rod 52 to adsorb an acrylic block 2.
