Description

Technical Field

[0001] The utility model relates to the technical field of PET processing, in particular to a two-way limiting plate fixture. Background Art

[0002] PET sheet is a sheet made of polyethylene terephthalate (PET) resin. It has the characteristics of high strength, wear resistance, corrosion resistance, high temperature resistance, etc. It is often used to make packaging boxes, billboards, signs, display racks and other products. PET sheet can also be used to make furniture, decorative materials, architectural models and other fields, and has broad application prospects.

[0003] At present, in the processing of PET sheets, such as cutting or punching, it is generally necessary to clamp and fix the sheets with the help of a clamp. For example, a PET sheet shearing device disclosed in Chinese Patent Announcement No. "CN214772250U" involves the technical field of shearing machines, which includes a workbench and a cutting machine. A pair of clamping plates are horizontally slidably arranged on the workbench, and a driving mechanism for driving the pair of clamping plates to move closer or farther from each other is arranged on the workbench. By clamping and limiting the sheet with a pair of clamping plates, the horizontal position of the sheet can be limited.

[0004] Conventional clamping devices mostly use a clamping method in which the two side clamps move relative to each other. This method can only achieve plane limitation in actual use, so the fixing effect is single. Considering the upper limitation of PET sheets to improve the stability during the processing operation, we propose a two-way limiting plate tooling fixture. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a two-way limiting plate fixture.

[0008] The clamp arm assembly includes a frame, which slides in the guide groove group through a guide sleeve. A wedge block is also arranged on the end surface of the frame. The bottom of the panel has a driving assembly for driving the two frames to move relative to each other.

[0009] Furthermore, the wedge block is sleeved and slidably mounted on the outer side of the frame, and a locking bolt is threadedly connected to the end surface of the wedge block.

[0010] Furthermore, at least two guide rods are fixed on the end surface of the frame, and a push plate is movably inserted between the two guide rods, wherein the push plate is an L-shaped rod structure and the bottom is in contact with the panel, and a spring is fixedly installed between the push plate and the guide rod.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 An embodiment of the utility model discloses a two-way limited plate fixture, the fixture comprises a base plate 1, specifically, a panel 2 is fixedly mounted above the base plate 1 through a column 6, two parallel guide groove groups 3 are provided on the end surface of the panel 2, and a clamp arm assembly 4 is slidably connected to each of the guide groove groups 3;

[0021] Among them, the clamping arm assembly 4 includes a frame 41, and the frame 41 is in a U-shaped structure. The frame 41 slides in the guide groove group 3 through a guide sleeve 42. The design of the guide sleeve 42 is to prevent the frame 41 from rotating. In this embodiment, the guide sleeve 42 can slide in the guide groove group 3 by cooperating with the slider and the slide groove. A wedge block 43 is also provided on the end face of the frame 41, and the bottom of the panel 2 has a driving assembly 5 for driving the two frames 41 to move relative to each other.

[0022] In some embodiments, the wedge block 43 in the utility model is sleeved and slid on the outside of the frame 41, and a locking bolt 44 is threadedly connected to the end face of the wedge block 43. That is to say, in this embodiment, the spacing of the above-mentioned wedge blocks 43 is adjustable, so that the spacing between the two wedge blocks 43 can be adjusted and adapted according to the size of the PET plate, thereby achieving higher applicability.

[0023] In addition, at least two guide rods 45 are fixed on the end surface of the frame 41, and a push plate 46 is movably inserted between the two guide rods 45, wherein the push plate 46 is an L-shaped rod structure, and the bottom is in contact with the panel 2, and a spring 47 is fixedly installed between the push plate 46 and the guide rod 45. Since the frame 41 can move up and down, in order to ensure that the side limit can be performed on PET plates of different thicknesses, the push plate 46 is designed to resist the PET plate in the utility model.

[0024] In addition, the driving assembly 5 in this embodiment includes a guide rod 51 fixed between the panel 2 and the base plate 1, and a ring 52 is slidably connected to the outer side of the guide rod 51, wherein a rotating plate 53 is fixedly installed on the outer side of the ring 52, and connecting rods 54 are pinned at both ends of the rotating plate 53, and the free end of the connecting rod 54 is pinned to the bottom of the frame 41.

[0025] Furthermore, a handle 55 is threadedly connected to the outer side of the collar 52 , and the rod end of the handle 55 can contact the outer side surface of the guide rod 51 .

[0026] In summary, when working, first place the PET sheet on the panel 2, then rotate the handle 55 in the opposite direction to separate its end from the guide rod 51, and then push the handle 55 to make the ring 52 drive the rotating plate 53 to rotate. When the rotating plate 53 rotates eastward, the connecting rod 54 will drive the frame 41 to move. After the two frames 41 move, the push plate 46 can clamp and limit the two sides of the PET sheet. Then, press the handle 55 downward to make the entire ring 52 move downward, thereby driving the frames 41 on both sides to move downward, and the wedge blocks 43 on the sides of the frames 41 can limit the upper part of the PET sheet, thereby completing the two-way limiting effect on the side and upper part of the PET sheet.

[0027] In order to adjust the height of the clamp, the upright post 6 in the utility model is configured as a telescopic rod with a self-locking structure.

[0028] That is to say, in the present invention, the push plates 46 on the two side frames 41 are clamped and limited on both sides of the PET sheet by operating the driving component 5. Thereafter, the driving component 5 can be further operated to move the wedge block 43 downward to complete the upper limit of the PET sheet, thereby achieving a two-way limit fixing effect on the PET sheet. The overall operation is simple, and only one driving component 5 needs to be controlled, which effectively improves the convenience and stability of the PET sheet during the processing, and at the same time improves the user's fixing efficiency of the PET sheet.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
