Example 1

According to the embodiment, through simple structural design and reasonable layout, the clamping mechanism for clamping the fabric is arranged on the fabric tensile tester. Through the shape design of the operating rod, the clamping and loosening operation of the clamping mechanism is realized by utilizing the change of the distance from the rotating shaft to the abutting point of the operating rod, the operation is simple and convenient, and the problem that a sample is unstable in the process of stretching the fabric by the traditional fabric stretching tester is effectively solved.

A clamping mechanism, as shown in figure 1, comprises a main clamp 1, an auxiliary clamp 2, a sliding shaft and an operating rod 3;

The sliding shaft is fixedly connected with the main clamp 1, and the auxiliary clamp 2 is slidably connected with the sliding shaft and moves along the sliding shaft so as to be matched with the main clamp 1 to realize clamping and loosening;

The operating rod 3 is provided with a rotating shaft 5 and an abutting part 10, the rotating shaft 5 is connected with the sliding shaft, a plurality of abutting points are distributed on the edge of the abutting part 10, the distance from the rotating shaft 5 to each abutting point is uneven, the operating rod 3 rotates around the rotating shaft 5 and abuts against the auxiliary clamp 2 through each abutting point, and the operating rod is used for driving the auxiliary clamp 2 to slide along the sliding shaft, so that clamping and loosening operations are realized.

The main clamp 1 and the sub clamp 2 are positioned opposite to each other, and they are engaged with each other to perform clamping and unclamping operations. The sliding shaft is fixedly connected with the main clamp 1, and the auxiliary clamp 2 is provided with a through hole matched with the sliding shaft. The sliding shaft penetrates through the through hole and is in sliding connection with the auxiliary clamp 2. This design enables the sliding movement of the secondary clamp 2 along the sliding axis, thereby effecting the clamping and unclamping operations. The operating rod 3 is provided with a rotating shaft 5 and an abutting part 10, a plurality of abutting points are distributed on the abutting part 10, and the rotating shaft 5 is connected with a sliding shaft. The abutment 10 abuts against the sub-jig 2 and the distances from the rotation shaft 5 to the several abutment points are uneven. When the operating rod 3 rotates around the rotating shaft 5, the operating rod 3 can apply pressure to the auxiliary clamp 2 in the direction of the main clamp 1 through the change of the distance from the rotating shaft 5 to a plurality of abutting points, and the auxiliary clamp 2 is pushed to slide along the sliding shaft in the direction of the main clamp 1, so that the main clamp 1 and the auxiliary clamp 2 are matched with each other to clamp the fabric sample. Conversely, when the operating lever 3 applies pressure in the opposite direction, the sub-clamp 2 moves away from the main clamp 1 along the sliding axis, releasing the fabric sample. Such a clamping mechanism is simple and easy to operate, and clamping and unclamping of the fabric sample can be achieved by movement of the lever 3. The clamping force is stable, and the stability of the fabric sample in the tensile test process is ensured. Meanwhile, the design of the clamping mechanism can be adjusted according to specific requirements so as to adapt to different types of fabrics and testing requirements.

Specifically, the distance from the rotation shaft 5 to the plurality of abutting points increases along a preset first direction, so as to drive the auxiliary clamp 2 to gradually approach the main clamp 1.

In practical application, the preset first direction is a rotation direction in which the operation lever 3 rotates around the rotation shaft 5 when pushing the sub-jig 2 to the main jig 1. When the distance between the sub-jig 2 and the main jig 1 is farthest, the distance from the rotation shaft 5 to the abutment portion 10 is closest; when the distance between the sub-jig 2 and the main jig 1 is closest, the distance from the rotation shaft 5 to the abutment portion 10 is farthest. When the operating lever 3 rotates about the rotation shaft 5, as the rotation angle of the operating lever 3 increases, the distance from the rotation shaft 5 to the abutment 10 increases, which results in a gradual increase in the distance of movement of the sub-jig 2 along the slide shaft 4. When the distance of the rotation shaft 5 to the abutment 10 is furthest, the sub-clamp 2 will be moved completely along the sliding shaft 4 to the main clamp 1, thereby achieving the clamping operation. The design has good controllability and stability. By adjusting the distance from the rotation shaft 5 to the abutment portion 10, the displacement amount of the sub-jig 2 along the slide shaft 4 can be controlled. Meanwhile, during the clamping process, the relative position between the main clamp 1 and the auxiliary clamp 2 is kept stable, so that the stability of the workpiece during the machining process is ensured.

In a specific embodiment, the sliding shaft comprises a first sliding shaft 4 and a second sliding shaft 11, the first sliding shaft 4 and the second sliding shaft 11 are parallel to each other, one end of each of the first sliding shaft 4 and the second sliding shaft 11 is fixedly connected with the main clamp 1, and the other end of each of the first sliding shaft and the second sliding shaft is connected with the rotating shaft 5.

Further, the first sliding shaft 4 and the second sliding shaft 11 are respectively provided with a perforation matched with the rotating shaft 5, the rotating shaft 5 penetrates through the perforation, one end of the rotating shaft 5 is connected with the first sliding shaft 4, and the other end of the rotating shaft is connected with the second sliding shaft 11.

The clamping mechanism comprises a first sliding shaft 4 and a second sliding shaft 11 which are parallel to each other. The first sliding shaft 4 and the second sliding shaft 11 are respectively fixedly connected with the main clamp 1 at one end and connected with the rotating shaft 5 at the other end. Such a design can ensure that the sub-jig 2 moves more stably toward the main jig 1 along the first slide shaft 4 and the second slide shaft 11. The design of the clamping mechanism can enable the movement of the main clamp and the auxiliary clamp to be more stable and uniform, and the result is more accurate and reliable. In addition, the clamping mechanism can be flexibly adjusted and changed according to specific requirements so as to adapt to different types of fabrics and testing requirements. In the use, the user only need through the action bars and can easily carry out surface fabric clamp and take off, need not to consume too much time and energy.

In a specific embodiment, the first sliding shaft 4 and the second sliding shaft 11 are respectively sleeved with an elastic piece 6, and the elastic piece 6 is used for pushing the auxiliary clamp 2 to move towards the opposite direction of the main clamp 1.

In practical applications, the elastic members 6 with different materials can be selected according to different needs, and in this embodiment, the elastic members 6 have a spring structure. The function of the auxiliary clamp is to enable the auxiliary clamp 2 to move towards the opposite direction of the main clamp 1, so that the reset is realized. The choice of the spring can be adjusted according to specific requirements so as to adapt to the elasticity requirements of different materials. The use of a spring as the resilient member has the advantage that it provides a reliable resilience and stable return characteristics. When the sub-clamp 2 completes the clamping operation, the spring is compressed, storing the elastic energy. Once the pressure is released, the spring will quickly return to its original state, pushing the secondary clamp 2 back to its original position, ready for the next test. The design of the elastic member 6 on the sliding shaft 4 makes the clamping mechanism more flexible and efficient, because it not only can immediately complete the clamping operation, but also can quickly recover and prepare for the next round of testing. Meanwhile, the spring is used as an elastic piece, so that durability and reliability are brought, and long-time stable use is ensured.

In a specific embodiment, the main clamp 1 is provided with a first clamping part 12, the auxiliary clamp 2 is provided with a second clamping part 13, and the first clamping part 12 and the second clamping part 13 are opposite;

the first clamping part 12 and the second clamping part 13 are respectively provided with engagement teeth 9 for increasing the clamping force to provide a better gripping effect.

The engagement teeth 9 are located on the first clamping portion 12 and the second clamping portion 13 and are in a saw-tooth or tooth-like structure. When the workpiece is clamped on the first clamping portion 12 and the second clamping portion 13, these biting teeth 9 are inserted into the surface of the workpiece, thereby increasing the clamping force. Due to the shape and arrangement of the teeth 9 they are able to effectively increase friction and gripping forces providing a more secure gripping effect. By increasing the clamping force, the biting teeth 9 can ensure that the workpiece is firmly fixed to the clamp during clamping, preventing the workpiece from slipping or shifting. This is particularly important for workpieces requiring high precision machining or stable positioning. In addition, the teeth 9 provide a more uniform clamping force distribution, avoiding damage or deformation of the workpiece due to concentrated stresses. In practical applications, the number, shape and distribution of the teeth 9 may be adjusted and optimized according to the specific workpiece shape and clamping requirements.

In a specific embodiment, the auxiliary clamp 2 is provided with a wear-resistant member 7, the abutting portion 10 abuts against the wear-resistant member 7, and the wear-resistant member 7 is used for preventing the operating rod 3 from directly rubbing against the auxiliary clamp 2.

In practical application, the wear-resistant piece 7 with different materials can be selected according to different requirements, and in this embodiment, the wear-resistant piece 7 is a racing steel sheet. Its main function is to prevent direct friction between the operating lever 3 and the secondary clamp 2. This design can effectively prolong the service life of the operating lever 3 and the sub-jig 2, and reduce abrasion and damage due to friction. In this embodiment, the wear-resistant member 7 is made of a steel sheet as a material selection. The steel sheet has excellent wear resistance and corrosion resistance, can bear larger friction force and pressure, and has good surface smoothness. This enables smooth movement of the operating lever 3 when in contact with the secondary clamp 2, under the protection of the wear part 7, while reducing the impact of wear and friction on the mechanism performance. By providing the wear-resistant member 7 on the sub-jig 2, not only the operation lever 3 and the sub-jig 2 are protected from direct friction, but also the stability and reliability of the entire clamping mechanism are improved.

In a specific embodiment, the auxiliary clamp 2 is provided with a protrusion, the main clamp 1 is provided with a limiting part 8 matched with the protrusion, the protrusion is located in the limiting part 8 and moves along the limiting part 8, and the limiting part 8 is used for maintaining the sliding stability of the auxiliary clamp 2 along the sliding shaft 4. In order to maintain the stability of the sliding of the auxiliary clamp 2 along the sliding shaft 4, the main clamp 1 is provided with a limit part 8 matched with the protrusion of the auxiliary clamp 2. The function of the limit 8 is to avoid the sub-clamp 2 from rattling during sliding, causing unnecessary errors or damage.

Preferably, the distance between the first clamping part 12 and the second clamping part 13 is 0-10 mm.

In the present embodiment, the pitch of the first clamping portion 12 and the second clamping portion 13 is preferably set between 0 and 10 mm. This choice is based on the gripping requirements of the various and specific fabrics. Considering the characteristics of different thicknesses, softness, textures and the like of the fabric, the clamping mechanism needs to have the capacity of maximally opening 10 mm. The variety of fabrics means that the clamping mechanism needs to accommodate fabrics of different materials and thicknesses. By adjusting the distance between the first clamping part 12 and the second clamping part 13, various fabrics can be clamped, and the soft treatment of the fabrics is ensured while the clamping force requirement is met. Smaller pitches can provide a stronger grip while larger pitches can accommodate thicker or softer fabrics. Through setting up the interval of first clamping part 12 and second clamping part 13 between 0 to 10mm, can adapt to the variety and the special demand of surface fabric, provide sufficient flexibility to satisfy the centre gripping requirement of different materials, thickness and special characteristic's surface fabric, and ensure security and the accuracy nature in the centre gripping process.
