Description

Technical Field

[0001] This utility model relates to the field of fixtures, specifically a fixed adjustable experimental processing fixture. Background Technology

[0002] Laboratory fixtures are tools used to fix, support, position, or adjust experimental objects during experiments, and are widely used in various laboratories such as physics, chemistry, biology, and mechanical engineering. Their design aims to ensure experimental accuracy and repeatability, reduce human error, and improve experimental efficiency. Depending on the experimental requirements, the materials, structure, stability, and resistance to high temperatures or corrosion of the fixtures also require higher performance. They not only adapt to different experimental environments but also support dynamic adjustments during the experiment, enabling researchers to perform precise measurements and operations. Therefore, laboratory fixtures occupy an important position in modern scientific research and are key tools for ensuring the smooth conduct of experiments and the accuracy of data.

[0003] In workpiece machining, an easily adjustable and secure fixture is typically required to ensure stable workpiece fixation during experiments and support multi-directional adjustment. This fixture can be precisely adjusted according to specific experimental requirements and fix the workpiece at the edge of the experimental chamber for observation of the experimental process through a transparent chamber. Traditional fixtures have limited applicability and cannot meet complex experimental needs, thus affecting the accuracy of testing and machining results. Therefore, a fixed adjustable experimental machining fixture is proposed to address the shortcomings of traditional fixtures in terms of adaptability and flexibility, ensuring stable and reliable fixation and adjustment functions under various experimental conditions, thereby improving the accuracy and efficiency of experiments.

[0021] The preferred embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the preferred embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention.

[0022] Example 1, as Figure 1-4 As shown, this embodiment provides a fixed adjustable experimental processing fixture, including a fixture base 1 body, a vertical fixing plate 2 body, and a concave fixture plate 3 body. The lower plate 14 of the fixture base 1 body has four countersunk threaded holes 13 of the same size. The countersunk threaded holes 13 are connected and fixed to the connecting threaded holes 4 below the vertical fixing plate with bolts. The vertical fixing plate has symmetrical fixing threaded holes 5 and clamping threaded holes 6 with the same spacing. The fixing concave fixture bolts 9 connect the fixing threaded holes 5 and the concave fixture connecting threaded holes 12, and the height can be adjusted by adjusting the connection position. The concave fixture plate has three symmetrical transverse clamping threaded holes 11. The experimental workpiece on the workpiece platform 10 is clamped by transverse clamping bolts 8 and two front and rear clamping bolts 7 on the vertical fixing plate.

[0023] refer to Figure 2 The clamping body base is provided with four countersunk threaded holes 13 of the same size for connecting the vertical fixing plate to the connecting threaded holes 4.

[0024] As a technical optimization of this utility model, the countersunk threaded hole enables the clamping body base to fit tightly with the processing platform.

[0025] refer to Figure 3 In addition to four identical threaded holes 4, the vertical fixing plate has symmetrical and equally spaced fixing threaded holes 5 and clamping threaded holes 6. The fixing concave clamping bolts 9 are used to fix the threaded holes to connect the concave clamping plate, and the front and rear clamping bolts 7 are used to clamp the workpiece.

[0026] As a technical optimization of this utility model, by setting symmetrical threaded holes with the same spacing but different functions, and through the connection and clamping action of bolts, the concave clamp plate can be adjusted up and down and clamped back and forth on the vertical fixed plate.

[0027] refer to Figure 4 After connecting the concave clamp threaded hole 12 to the vertical fixing plate threaded hole 5 by fixing the concave clamp bolt 9, place the workpiece used in the experiment on the work platform 10, and fix the workpiece left and right by the horizontal clamping bolt 8. If front and back fixation is required, fix it by the front and back clamping bolts 7 to facilitate the experiment.

[0028] As a technical optimization of this utility model, by setting three symmetrical transverse clamping bolts 8, the workpiece can be clamped in different transverse directions, and the front and rear clamping bolts 7 can clamp the workpiece in more directions. The concave design principle allows the workpiece to pass through the workpiece when machining holes to avoid machining fixtures.

[0029] The core objective of this invention is to ensure that the workpiece is stably and accurately fixed on the work platform during experimentation or processing through a reasonable mechanical structure and clamping device. This device utilizes a base, a vertical fixing plate, a clamping plate, and various clamping bolts to provide multi-directional clamping support, ensuring that the workpiece will not loosen or shift during the entire processing, thereby improving processing accuracy and efficiency. The specific working principle is as follows: Base and vertical fixing plate connection: The user first tightly connects the clamping body base to the vertical fixing plate using bolts, ensuring the entire device is stable and secure. Clamping plate adjustment: The clamping plate is concave and fixed at the required height, ensuring that the clamp can effectively surround and support the workpiece. Workpiece placement: The workpiece to be processed is placed on the workpiece platform 10, which typically has support points or positioning slots to ensure the initial position of the workpiece is fixed. Lateral clamping: The workpiece is first laterally clamped using the lateral clamping bolts 8. This step ensures that the workpiece is firmly clamped in the horizontal direction, preventing displacement due to the torque generated during processing. Front and rear clamping: If it is necessary to further enhance the clamping force or ensure the stability of the workpiece in more directions, the front and rear clamping bolts 7 can be used to clamp the workpiece in the front and rear directions through the clamping threaded holes 6 to further fix the position of the workpiece.

[0030] Although the present invention has been described in detail through the foregoing embodiments, those skilled in the art can still make appropriate modifications to the technical solutions in the foregoing embodiments or make equivalent substitutions for certain technical features according to the technical requirements. Any modifications, equivalent substitutions, or improvements made within the spirit and basic principles of the present invention should be considered to fall within the protection scope of the present invention.
