Description

Technical Field

[0001] The present invention relates to the technical field of testing, and particularly relates to a fixing device for testing the strength of accordion fabric. Background Art

[0002] The accordion is a reed instrument that can not only perform solo but also accompany. It can not only play beautiful melodies in a single voice, but also play multi-voice music, and can even play rich harmonies with both hands like a piano. The accordion has a grand sound and rich timbre variations. The ingenious combination of fingers and bellows enables it to play various styles of music, which is incomparable to many other instruments. In addition to solo performances, it can also participate in duets and ensembles. It can be said that an accordion is a small band. During the production of existing accordions, it is necessary to conduct tensile tests on the fabrics of the accordions to detect the quality of the accordion fabrics. Generally, the accordion fabrics are clamped by devices such as clips, and the clips are provided with concave and convex sawteeth, and the stress points are relatively small, so it is easy to scratch or even damage the edges of the fabrics when pulling the fabrics.

[0003] The patent document with the publication number CN209802856U provides a fixing device for testing the strength of accordion fabric, including a base. A rectangular support frame is arranged inside the base, and through holes are opened on the base, and a rectangular notch is opened on the outer wall of the base. The end of the support frame far from the base is sleeved with the fabric to be fixed, and a "return" shaped moving frame is arranged between the support frame and the base. A connecting block is arranged on the moving frame, and one end of the moving frame is connected with a fixing frame. An annular groove is opened on the fixing frame, and a locking bar is arranged in the groove of the fixing frame. Through holes are opened at both ends of the locking bar, and fixing screws are arranged in the through holes at both ends of the locking bar. This fixing device for testing the strength of accordion fabric is provided with a fixing frame, which clamps the fabric as a whole, avoiding a certain point on the fabric from receiving a large pulling force and improving the effect of fixing the fabric.

[0004] The existing fixing method for accordion fabric is relatively traditional, the fixing effect on the fabric needs to be improved, and the fixing device is not convenient to replace. Summary of the Invention

[0021] Through the linkage mechanism of the pneumatically driven trapezoidal clamping block and the puncture needle, this solution achieves double fixation. The symmetrically arranged puncture needles adopt a staggered layout, avoiding local stress concentration on the fabric, enhancing the fixation effect while reducing damage.

[0022] After the gas drives the clamping block to close through the first cylinder in this solution, the second cylinder is synchronously triggered to push the puncture needle through the fabric, forming a composite fixation mode of "clamping + puncturing", breaking through the singularity of traditional pure mechanical clamping. The puncture needle is quickly retracted through the return spring, avoiding interference from residual puncture holes to subsequent tests.

[0023] The fixture base of this solution can be quickly replaced through the threaded connection between the external threaded cylinder and the cylinder, and for fabrics of different thicknesses or materials, different sizes of fixture bases can be replaced, such as adjusting the width of the triangular notch or the density of the puncture needles, expanding the applicable range of the equipment.

[0025] Through the cooperation of the intelligent pressure gauge and the linear motor, this solution achieves precise control of air pressure, realizes the purpose of pressure self-adaptation, presets the air pressure threshold according to the fabric strength, and the linear motor dynamically adjusts the piston plate stroke to avoid overpressure damage to the fabric or slippage caused by insufficient clamping. The dual gas paths are independently controlled, and the air supply pipes for the top and bottom fixtures supply air separately, allowing different pressures to be applied to the upper and lower fixtures.

[0026] The present invention solves the problems of easy damage to the fabric and poor adaptability of the traditional clamping device through pneumatic puncture linkage and modular fixtures; the dual-track synchronous adjustment and intelligent air control improve the test accuracy and reliability, constituting a set of efficient, precise and expandable special test system.

[0054] Working mode: When in use, the power supply and the intelligent controller 12 are turned on to perform electrical control. This is the prior art and will not be elaborated here. The two ends of the accordion fabric are respectively connected to the two fabric clamping structures 3. The two switches 13 are set to respectively control the two fabric clamping structures 3 to clamp and fix the accordion fabric. The pressure values of the two intelligent pressure gauges 85 are set through the intelligent controller 12. Specifically, one end of the accordion fabric is inserted into the triangular notch 311 and is located between the two trapezoidal clamping blocks 37. First, the top of the accordion fabric is clamped. Press one switch 13, and the linear motor 83 pushes the piston plate 82 to move. The piston plate 82 slides in the air cylinder 81, and the gas is sent into the connecting elbow 36 through the top fixture air supply pipe 5, and then sent into the two first branch pipes 381 through the insertion pipe 33. The gas enters the two first air cylinders 38 through the two first branch pipes 381. The two first air cylinders 38 push the two trapezoidal clamping blocks 37 to approach each other. The two trapezoidal clamping blocks 37 clamp and fix the accordion fabric through the two silica gel pads 310.

[0055] At the same time, the gas enters the two second air cylinders 384 through the second branch pipe 382 and the two third branch pipes 383. The two second air cylinders 384 push the corresponding moving plates 39 to move. The moving plates 39 drive a plurality of puncture needles 391 to penetrate out of the second through holes 3101. The symmetrically arranged plurality of puncture needles 391 are symmetrically and staggeredly arranged and can be inserted into the accordion fabric to further improve the fixation of the accordion fabric. After reaching the air pressure value, the linear motor 83 stops working, and then the other switch 13 is controlled to work, so that the gas provides air pressure for the lower fabric clamping structure 3 through the bottom fixture air supply pipe 7, clamps and fixes the bottom end of the accordion fabric, and then the strength test of the accordion fabric is carried out.

[0056] The two synchronous motors 26 drive the two threaded rods 22 to rotate. The two threaded rods 22 drive the mounting plate 25 to move upward through the two sliders 23. The mounting plate 25 drives the upper fabric clamping structure 3 to move upward through the tension sensor 4, and the accordion fabric can be pulled, and the strength of the accordion fabric can be detected. The tension sensor 4 directly reflects the tension value and is displayed through the intelligent controller 12, realizing the strength test of the accordion fabric.

[0057] After the detection is completed, the two linear motors 83 are controlled in reverse. The air pressures of the first air cylinder 38 and the second air cylinder 384 decrease. The two trapezoidal clamping blocks 37 on the same fixture seat 31 move away from each other, and the two moving plates 39 move away from each other. Through the pulling force of the return spring 392, the moving plates 39 can be quickly reset, and the puncture needles 391 are retracted into the trapezoidal grooves 371.

[0058] The fixture seat 31 is threadedly connected to the cylinder 34 through the external thread cylinder 331, which can facilitate the replacement of the fixture seat 31. Select a suitable fixture seat 31 according to the size of the accordion fabric for use.

Through the cooperation of the ball bearings 232 and the slide rail 21, the friction between the slider 23 inside the slide rail 21 can be reduced.

[0061] Refer to Figure 2 , in this embodiment, a snap ring 51 is fixedly installed at the bottom of the mounting plate 25, and the top jig air supply pipe 5 is located within the snap ring 51. The snap ring 51 is used to support the top jig air supply pipe 5. All the structural shapes, dimensions, and materials of Example One are included in this application. For meeting specific usage situations, selections and adjustments can be made.
