Description

Technical Field

[0001] The present application relates to a tensile testing machine, and more particularly to a specimen receiving device for the tensile testing machine. Background Art

[0002] Tensile testing machine is also known as universal material testing machine. Universal testing machine is a mechanical force testing machine used to perform mechanical property tests such as static load, stretching, compression, bending, shearing, tearing, peeling, etc. on various materials. It is suitable for various physical and mechanical property tests of plastic plates, pipes, special-shaped materials, plastic films, rubber, wires and cables, steel, glass fiber and other materials for material development, physical property testing, teaching research, quality control and other indispensable testing equipment.

[0003] Tensile testing machines are usually equipped with fixtures for holding the test specimens. As an important part of the instrument, the stability of the fixture in holding the test specimens is also an important factor in whether the test can be carried out smoothly and the accuracy of the test results.

[0004] Since the tensile testing machine needs to clamp many different types of specimens, the specimens have different shapes and sizes. When the fixture clamps the specimens, the specimens may slip and fall, and are prone to bumps and damage. In addition, when conducting certain experiments, the specimens may break and cause fragments to splash into the tensile testing machine, causing a cleaning burden. Utility Model Content

[0005] The present application provides a sample receiving device for a tensile testing machine, which solves the problem of sample slippage causing damage due to bumps and the problem of sample breakage fragments splashing and scattering, causing a cleaning burden.

[0006] The technical solution adopted in this application is:

[0007] A tensile testing machine specimen receiving device, the tensile testing machine is provided with a clamp, the receiving device comprises a base and a material baffle plate, the clamp comprises a positioning end fixed to the bottom wall of the testing machine, the base is detachably sleeved on the outside of the positioning end, the material baffle plate is arranged on the base and extends along the base to the clamping end of the clamp.

[0008] In a preferred implementation of a tensile testing machine specimen receiving device, the receiving device includes a limiting assembly connecting a base and a positioning end.

[0009] In a preferred implementation of a tensile testing machine specimen receiving device, the limiting assembly includes a limiting protrusion and a limiting groove matched with the limiting protrusion, one of the limiting protrusion and the limiting groove is located at the positioning end, and the other is located at the base.

[0010] In a preferred implementation of a tensile testing machine specimen receiving device, the baffle plate is circumferentially arranged around the base.

[0011] In a preferred implementation of a tensile testing machine specimen receiving device, the bottom end of the baffle plate is fixedly connected to the base.

[0012] or,

[0013] The baffle plate is detachably connected to the base.

[0014] In a preferred implementation of the tensile testing machine specimen receiving device, the inner diameter of the baffle plate gradually increases along the extension direction from the base.

[0015] or,

[0016] The material blocking plate comprises a reinforcing section perpendicular to the base and an extending section obliquely extending along the reinforcing section, wherein the inner diameter of the extending section is greater than the inner diameter of the reinforcing section.

[0017] In a preferred implementation of the sample receiving device of the tensile testing machine, the projection of the material blocking plate in the radial direction at least partially covers the clamp.

[0018] In a preferred implementation of a tensile testing machine specimen receiving device, the base includes a proximal end abutting against the positioning end, the base extends radially from the proximal end, the extended end forms a distal end, and the height of the distal end is not less than the height of the proximal end.

[0019] In a preferred implementation of a tensile testing machine specimen receiving device, a sealing member is provided between an inner side wall of the base and an outer side wall of the positioning end.

[0020] In a preferred implementation of a tensile testing machine specimen receiving device, a flexible sealing ring is provided on the inner side wall of the base, and the flexible sealing ring forms a sealing member.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0022] (1) The base and the baffle plate are provided to protect the surrounding of the fixture. When the sample slips and the fragments fly, the baffle plate blocks and rebounds the sample or the fragments, so that the sample and the fragments fall on the base. At the same time, since the baffle plate is provided on the base, after the sample and the fragments fall on the base, they will not move along the base and fall due to the blocking of the baffle plate, so that the sample can be received and the fragments can be collected. Since the base is detachable, the fragments can be cleaned up in a centralized manner by disassembling the base, which reduces the cleaning burden and is conducive to keeping the internal cleanliness of the tensile testing machine.

[0023] (2) The connection between the base and the positioning end is achieved through a limiting component. The limiting component is configured in the form of a limiting protrusion and a limiting groove with a simple structure. The connection between the base and the positioning end is achieved by inserting the limiting protrusion into the limiting groove, and the base is limited, which facilitates the disassembly of the base.

[0024] (3) A material baffle is arranged around the base to surround the fixture and the specimen at the fixture, protecting the specimen from multiple directions to prevent the specimen from slipping and falling from the gap, enhancing the specimen receiving effect, and at the same time, blocking the flying debris from multiple angles to prevent the debris from scattering inside the tensile testing machine and causing inconvenience in cleaning.

[0025] (4) By setting a fixed connection between the baffle plate and the base, the fixing stability of the baffle plate is enhanced, the baffle plate is prevented from being skewed, and the baffle effect of the baffle plate is ensured. At the same time, the baffle plate can be installed while the base is installed, simplifying the installation steps. Alternatively, by setting a detachable connection between the baffle plate and the base, it is possible to choose whether to install the baffle plate according to actual needs, and it is convenient to replace baffle plates of different sizes.

[0026] (5) By gradually increasing the inner diameter of the material baffle plate, the material baffle plate is flared, the structure is simple, and the material baffle range of the material baffle plate is increased. Alternatively, by providing a reinforcement section and an extension section, on the one hand, the reinforcement section perpendicular to the base makes the fixation of the material baffle plate on the base more stable, and on the other hand, the extension section with an increased inner diameter expands the material baffle range of the material baffle plate.

[0027] (6) The projection of the material blocking plate in the radial direction at least partially covers the fixture, so that the material blocking plate has a certain height, thereby satisfying the shielding effect on the sample and debris.

[0028] (7) By setting the height of the distal end of the base to be not less than the height of the proximal end, that is, the base as a whole has an inclined angle, the base's supporting effect on the sample and the collection effect on the debris are enhanced, thereby preventing the sample or debris from sliding down the base and falling.

[0029] (8) By providing a seal, the connection sealing between the base and the positioning end is strengthened, the connection stability is enhanced, and the accumulation of fragments or debris in the connection gap is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

The clamp 1 includes a positioning end 10 fixed to the bottom wall of the testing machine, and the base 2 is detachably mounted on the outside of the positioning end 10. The material baffle plate 3 is arranged on the base 2 and extends along the base 2 to the clamping end of the clamp 1.

[0042] The base 2 and the baffle plate 3 are provided to protect the area around the fixture 1. When the sample slips and fragments fly, the baffle plate 3 blocks and rebounds the sample or fragments, so that the sample and fragments fall on the base 2. At the same time, since the baffle plate 3 is provided on the base 2, after the sample and fragments fall on the base 2, they will not move and fall along the base 2 due to the blocking of the baffle plate 3, thereby achieving the reception of the sample and the collection of the fragments. Since the base 2 is detachable, the fragments can be centrally cleaned by disassembling the base 2, which reduces the cleaning burden and is beneficial to keeping the internal cleanliness of the tensile testing machine.

[0043] In one embodiment, the receiving device includes a limiting component connecting the base 2 and the positioning end 10 .

[0044] Furthermore, if Figure 2 As shown, the limiting assembly includes a limiting protrusion 4 and a limiting groove 5 matched with the limiting protrusion 4 , one of the limiting protrusion 4 and the limiting groove 5 is located at the positioning end 10 , and the other is located at the base 2 .

[0045] The connection between the base 2 and the positioning end 10 is achieved through a limiting component. The limiting component is configured in the form of a limiting protrusion 4 and a limiting groove 5 with a simple structure. The connection between the base 2 and the positioning end 10 is achieved by inserting the limiting protrusion 4 into the limiting groove 5, and the base 2 is limited, which facilitates the disassembly of the base 2.

[0046] Preferably, a limiting groove 5 is provided at the positioning end 10 , and a limiting protrusion 4 is provided at the base 2 , and the limiting protrusion 4 is inserted into the limiting groove to realize the connection and assembly between the base 2 and the positioning end 10 .

[0047] In one embodiment, the material blocking plate 3 is circumferentially arranged around the base 2 .

[0048] The baffle plate 3 is arranged circumferentially around the base 2 to circumferentially surround the fixture 1 and the sample located at the fixture 1, protecting the sample from multiple directions to prevent the sample from slipping and falling from the gap, enhancing the receiving effect of the sample, and at the same time blocking the flying debris from multiple angles to prevent the debris from scattering inside the tensile testing machine and causing inconvenience in cleaning.

[0049] In one embodiment, the bottom end of the material blocking plate 3 is fixedly connected to the base 2, or the material blocking plate 3 is detachably connected to the base 2.

At the same time, the installation of the material blocking plate 3 can be completed while the base 2 is installed, simplifying the installation steps. Alternatively, by setting the material blocking plate 3 to be detachably connected to the base 2, it is possible to choose whether to install the material blocking plate 3 according to actual needs, and it is convenient to replace the material blocking plates 3 of different sizes.

[0051] The bottom end of the baffle plate 3 is fixedly connected to the base 2, which can be achieved by bolts or other fasteners. The baffle plate 3 and the base 2 can be detachably connected. An opening can be set in the base 2, and the baffle plate 3 is provided with an insert that cooperates with the opening. The insert is inserted into the opening to achieve the assembly of the baffle plate 3 and the base 2.

[0052] In one embodiment, Figure 3 As shown, the inner diameter of the baffle plate 3 gradually increases along the extension direction from the base 2, or the baffle plate 3 includes a reinforcing section 6 perpendicular to the base 2 and an extension section 7 extending obliquely along the reinforcing section 6, and the inner diameter of the extension section 7 is greater than the inner diameter of the reinforcing section 6.

[0053] By gradually increasing the inner diameter of the material blocking plate 3, the material blocking plate 3 is trumpet-shaped, the structure is simple, and the material blocking range of the material blocking plate 3 is increased. Alternatively, by providing the reinforcing section 6 and the extension section 7, on the one hand, the reinforcing section 6 perpendicular to the base 2 makes the fixing of the material blocking plate 3 on the base 2 more stable, and on the other hand, the extension section 7 with an increased inner diameter expands the material blocking range of the material blocking plate 3.

[0054] In one embodiment, a projection of the blocking plate 3 in the radial direction at least partially covers the fixture 1 .

[0055] By arranging the projection of the material blocking plate 3 in the radial direction to at least partially cover the fixture 1, the material blocking plate 3 has a certain height, thereby satisfying the shielding effect on the sample and the debris.

[0057] By setting the height of the distal end 9 of the base 2 to be not less than the height of the proximal end 8, that is, the base 2 has an overall tilt angle, the base 2 can enhance its supporting effect on the sample and its effect on collecting debris, thereby preventing the sample or debris from sliding down the base 2 and falling.
