Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acrylic plate processing, in particular to an auxiliary tooling for acrylic plate processing. Background Technique
[0002] Acrylic plates are polymerized from methyl methacrylate monomers, that is, polymethyl methacrylate plates, which are a kind of organic glass processed by special processes.
[0003] During the processing of acrylic plates, fixtures are needed to fix the acrylic plates to prevent them from moving or deforming during processing. The design of the fixtures should take into account the material characteristics and processing requirements of the acrylic plates to ensure that the clamping force is appropriate and avoid damaging the plates.
[0004] When the clamping force of the fixture is too large, excessive pressure will be generated on the surface of the workpiece, which may cause plastic deformation of the workpiece, thus affecting the dimensional accuracy and shape accuracy of the workpiece. When the clamping force of the fixture is too small, the workpiece will also shift due to loosening during processing, thereby affecting the processing accuracy. Therefore, there is an urgent need for a fixture that can adjust the clamping force. Content of the Utility Model

Guide rings are fixedly arranged at both ends of the upper clamping plate, limiting parts are movably arranged on the outer sides of the guide rings, and a plurality of limiting cavities are correspondingly arranged on the outer sides of the columns for adapting to the limiting parts.
[0008] In addition, the preferred structure is that a screw is rotatably installed on the column at one end of the lower clamping plate, and a threaded hole is correspondingly arranged on the column for adapting to the screw.
[0009] In addition, the preferred structure is that pressing columns are fixedly arranged at one ends of the screws, and pressing column grooves are correspondingly arranged on the top of the lower clamping plate for adapting to the pressing columns.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Refer to Figures 1-5, An auxiliary tooling for acrylic sheet processing, including an acrylic sheet 1 and clamping components clamped on both sides thereof. The clamping components include a lower clamping plate 2. Columns 3 are fixedly arranged at both ends of the lower clamping plate 2. An upper clamping plate 4 is vertically movably arranged above the lower clamping plate 2, and silicone parts 40 are fixedly arranged at the bottom of the upper clamping plate 4. Guide rings 41 are fixedly arranged at both ends of the upper clamping plate 4. Limiting parts 62 are movably arranged on the outer sides of the guide rings 41, and a plurality of limiting cavities 32 are adaptively opened on the outer sides of the columns 3 corresponding to the limiting parts 62.
[0022] Among them, a screw rod 5 is rotatably installed on the column 3 at one end of the lower clamping plate 2, and a threaded hole 31 is adaptively opened on the column 3 corresponding to the screw rod 5. A pressure column 51 is fixedly arranged at one end of the screw rod 5, and a pressure column groove 21 is adaptively opened on the top of the lower clamping plate 2 corresponding to the pressure column 51. A knob is arranged at one end of the outer side of the screw rod 5. By rotating the knob, the screw rod 5 can be driven to rotate in the threaded hole 31, and thus the pressure column 51 can be driven to move in the pressure column groove 21.
[0023] Among them, the guide rings 41 are all sleeved on the outer sides of the columns 3, and guiding parts are adaptively arranged on the inner walls of the guide rings 41 corresponding to the columns 3. Guiding cavities are adaptively opened on the outer sides of the columns 3 corresponding to the guiding parts on the guide rings 41. Through the adaptive arrangement of the guiding parts and the guiding cavities, it can be ensured that the guide rings 41 and the upper clamping plate 4 remain stable during the moving process.
[0024] Among them, through holes 42 are opened on the outer walls of the guide rings 41. Spring cavities 43 are opened on both sides of the through holes 42, and springs 61 are arranged outward in the spring cavities 43. The other ends of the springs 61 are all connected to the pull plates 6. Limiting parts 62 are fixedly arranged on the pull plates 6, and the limiting parts 62 are all adapted to the through holes 42 and the limiting cavities 32.
[0025] In this embodiment, by clamping and fixing both ends of the acrylic sheet between the lower clamping plate 2 and the upper clamping plate 4 in the clamping component, the fixed clamping of both ends of the acrylic sheet can be realized, so as to facilitate the user to process the acrylic sheet.
[0026] When the user needs to clamp the acrylic sheet, only need to place the acrylic sheet above the lower clamping plate 2, and then rotate the knob on the screw rod 5 through the handle. In this way, the rotation of the screw rod 5 can be used to make the pressure column 51 move towards the acrylic sheet. Make one side of the acrylic sheet contact with the column 3 and the other side contact with the pressure column 51, so as to realize the clamping and positioning of the side of the acrylic sheet. It should be noted that a damping mechanism in the prior art is adaptively arranged between the screw rod 5 and the threaded hole 31, and the user can only rotate the screw rod 5 through a wrench.
[0027] Further, the user only needs to pull the pull plates 6 on the guide rings 41 on both sides of the upper clamping plate 4 outwards. At this time, the limiting members 62 on the pull plates 6 can be disengaged from the limiting cavities 32 on the columns 3, and the springs 61 are stretched. Then the user only needs to move the upper clamping plate 4 above the acrylic plate to press the acrylic plate. After the position of the upper clamping plate 4 is adjusted, the user only needs to release the pull plates 6 on both sides, so that the pull plates 6 and the limiting members 62 are automatically reset by the elastic force of the springs 61. Thus, the limiting members 62 can pass through the through holes 42 again and move into other limiting cavities 32 to fix the guide rings 41 and the upper clamping plate 4 again. Thus, the fixed clamping of the acrylic plate can be realized.
[0028] It should be noted that a silica gel member 40 is fixedly arranged at the bottom of the upper clamping plate 4. Since the silica gel member 40 has a certain elasticity, this can ensure that when the upper clamping plate 4 presses on the acrylic plate, there is a certain adjustment space between the limiting member 62 and the limiting cavity 32, and the phenomenon that the limiting member 62 cannot align with the limiting cavity 32 will not occur. And flexible and thin silica gel pads are fixedly laid on all parts of the clamping assembly that contact the acrylic plate to prevent damage to the acrylic plate during the clamping process.
[0029] In the present utility model, the fixed clamping of the acrylic plate can be realized through the clamping assemblies on both sides. During the clamping process, the adjustment of the position of the upper clamping plate 4 can be realized through the arrangement of the limiting member 62 and the plurality of limiting cavities 32, and the adjustment of the position of the pressing column 51 can be realized through the screw rod 5. Thus, the adjustment of the horizontal clamping force and the vertical clamping force of the device can be realized.
[0030] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
