Description

Horizontal tensile testing machine Technical Field

[0001] This utility model relates to a material testing equipment, and more particularly to a horizontal tensile testing machine. Background Technology

[0002] The horizontal tensile testing machine is a multifunctional material testing instrument. It is mainly used for tensile testing of metallic and non-metallic materials to obtain mechanical property data. It is widely used in construction, machinery and technical monitoring, and is one of the main pieces of equipment in the mechanical testing laboratories of scientific research departments, universities and military units.

[0003] A tensile guide rail is provided on the horizontal tensile testing machine, and a movable support body is mounted on the tensile guide rail. The movable support body can move linearly based on the tensile guide rail to adapt to different specimen lengths.

[0004] Traditional horizontal tensile testing machines require manual movement of the moving support, which is then locked onto the tensile guide rail at fixed intervals using manual or hydraulic pins. This process is cumbersome, time-consuming, labor-intensive, and results in low testing efficiency.

[0005] In summary, the current problem is:

[0006] 1) The moving support in the horizontal tensile testing machine can only be moved manually;

[0007] 2) The movable load in the horizontal tensile testing machine locks its position on the tensile guide rail by means of "pin hole positioning", which can only be locked in a few fixed positions. Summary of the Invention

[0008] The purpose of this utility model is to provide a horizontal tensile testing machine in which the movable support body can be easily moved and stepless positioning and locking can be achieved.

[0009] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0010] A horizontal tensile testing machine includes a frame, a tensile guide rail, a movable support body, a wheel-rail mechanism, and a fixture. The tensile guide rail is mounted on the frame. The wheel-rail mechanism is mounted on the frame and equipped with a displacement drive motor that drives the wheel-rail mechanism to move. The movable support body is mounted on the wheel-rail mechanism and is capable of moving to a position that aligns with the direction of the tensile guide rail. The fixture is mounted on the movable support body.

[0011] Furthermore, the movable carrier is equipped with a rail clamping and locking mechanism, which is used to clamp the tension guide rail to lock the position of the movable carrier on the tension guide rail.

[0012] Furthermore, the specific structural form of the rail clamping locking mechanism is as follows: the movable carrier has an inwardly recessed rail clamping portion, and an upper clamping block and a lower clamping block are provided in the rail clamping portion; the upper clamping block is assembled at the top position of the rail clamping portion by a hydraulic cylinder mechanism, and the lower clamping block is fixedly provided at the bottom position of the rail clamping portion; under the driving action of the hydraulic cylinder mechanism, the upper clamping block can move downward toward the lower clamping block and perform a clamping action; the tension guide rail is located at the rail clamping portion of the movable carrier, the upper clamping block is located above the tension guide rail, and the lower clamping block is located below the tension guide rail; when the upper clamping block performs a downward clamping action, the upper clamping block and the lower clamping block cooperate with each other to achieve a clamping and locking effect on the tension guide rail; the upper clamping block and the lower clamping block provided in the rail clamping portion of the movable carrier together constitute the rail clamping locking mechanism.

[0013] Furthermore, the lower clamping block is equipped with an anti-wear pressure plate.

[0014] Furthermore, the shift drive motor is a servo motor.

[0015] Furthermore, the tension guide rail has a dual-rail configuration.

[0016] Furthermore, the horizontal tensile testing machine is also equipped with a main control system.

[0017] Furthermore, the clamp is a hydraulically driven clamp.

[0018] Compared with the prior art, the advantages of this horizontal tensile testing machine are as follows:

[0019] 1) In the horizontal tensile testing machine of this utility model, a displacement drive motor is used to drive the moving load to move its position, which is very convenient to operate;

[0020] 2) The movable support body in the horizontal tensile testing machine of this utility model is equipped with a rail clamping and locking mechanism, which enables positioning and locking at any position of the tensile guide rail, realizing stepless positioning and locking, and can adapt to specimens of various lengths and specifications.

[0025] The specific embodiments of this utility model are further described below:

[0026] This embodiment provides a horizontal tensile testing machine, which uses a displacement drive motor to drive the moving load to move its position, and achieves stepless positioning and locking for the moving load.

[0027] Referring to Figure 1, the horizontal tensile testing machine of this embodiment is based on a frame 1. Furthermore, for ease of description, one orientation of the horizontal tensile testing machine is defined as the testing orientation (as indicated by arrow B in Figure 1).

[0028] The horizontal tensile testing machine includes a tensile guide rail 2, a moving load body 3, a wheel-rail mechanism 4, a hydraulic source 5, and a clamp 7.

[0029] The tension guide 2 is a double-rail configuration and is installed on the frame 1.

[0030] The wheel-rail mechanism 4 is specifically configured for the mobile carrier 3 and is mounted on the frame 1. Specifically, a travel track is configured on the frame 1 for the wheel-rail mechanism 4, and the rollers of the wheel-rail mechanism 4 are placed on the travel track, enabling the wheel-rail mechanism 4 to move linearly based on the travel track.

[0031] The mobile carrier 3 is installed based on the wheel-rail mechanism 4, so that the mobile carrier 3 can move linearly based on the wheel-rail mechanism 4.

[0032] It should be noted that the movement direction of the wheel-rail mechanism 4 is matched with the direction of the tension guide rail 2. In other words, the movement direction of the moving support 3 is matched with the direction of the tension guide rail 2.

[0033] Referring to Figure 2, the wheel-rail mechanism 4 is equipped with a displacement drive motor 41 and a reducer 42, which are used to drive the rollers 43 of the wheel-rail mechanism 4 to rotate and roll, that is, to drive the entire wheel-rail mechanism 4 to move. It should be noted that Figure 4 shows only a small part of the wheel-rail mechanism 4, namely the displacement drive motor 41, the reducer 42 and the pair of rollers 43 driven by it.

[0034] Both sides of the movable support body 3 have inwardly recessed parts. For ease of description, these parts are defined as rail clamping parts (as indicated by arrows A1 and A2 in Figure 3).

[0035] Each clamping section is further provided with an upper clamping block 31 and a lower clamping block 32. The upper clamping block 31 is assembled at the top position of the clamping section via a hydraulic cylinder mechanism, and the lower clamping block 32 is fixedly installed at the bottom position of the clamping section. Under the driving action of the hydraulic cylinder drive mechanism, the upper clamping block 31 can move downward toward the lower clamping block 32 and perform a clamping action.

[0036] It should be noted that in this embodiment, a hydraulic cylinder is provided inside the upper clamping block 31, and the upper clamping block 31 as a whole can be regarded as an assembly of the hydraulic cylinder. The piston rod of the hydraulic cylinder is assembled and connected to the top of the clamping rail portion. In this way, the upper clamping block 31 can perform a downward pressing action based on the top of the clamping rail portion. In other embodiments, the hydraulic cylinder drive mechanism provided for the upper clamping block 31 can also be implemented in other forms. For example, the cylinder body of the hydraulic cylinder can be assembled and connected to the top of the clamping rail portion, and the piston rod of the hydraulic cylinder can be assembled and connected to the upper clamping block 31, which can also drive the upper clamping block 31 to perform a downward pressing action.

[0037] Referring to Figure 4, when the movable carrier 3 is installed based on the wheel-rail mechanism 4, the tension guide rail 2 is located at the clamping parts on both sides of the movable carrier 3, the upper clamping block 31 is above the tension guide rail 2, and the lower clamping block 32 is below the tension guide rail 2. When the upper clamping block 31 presses downward, the upper clamping block 31 and the lower clamping block 32 cooperate to achieve a clamping and locking effect on the tension guide rail 2. The combination of the two essentially constitutes a rail clamping and locking mechanism, used to lock the position of the movable carrier 3 on the tension guide rail 2.

[0038] It should be noted that the hydraulic power required for the upper clamping block 31 is provided by the hydraulic source 5 (a prior art device), which is installed based on the wheel-rail mechanism 4 and can move with the wheel-rail mechanism 4.

[0039] It should be noted that an anti-wear bearing plate 33 is provided on the upward side of the lower clamping block 32 facing the tension guide rail 2. The anti-wear bearing plate 33 has two functions: firstly, the anti-wear bearing plate 33 has good wear resistance, thereby preventing mechanical wear; secondly, the anti-wear bearing plate 33 has a large coefficient of friction, which is conducive to the reliable clamping of the moving carrier 3 on the tension guide rail 2.

[0040] Referring to Figure 1, a clamp 7 is provided on the side of the movable support 3 facing the test direction. This clamp 7 is a hydraulically driven clamp, which is driven by hydraulic power provided by the hydraulic source 5. The clamp 7 is used to hold the sample.

[0041] The horizontal tensile testing machine is also equipped with a main control system 6. All electrical equipment in the horizontal tensile testing machine, such as the displacement drive motor 41 of the wheel-rail mechanism 4 and the upper clamping block 31 mounted on the moving carrier 3, are controlled by the main control system 6.

[0042] The horizontal tensile testing machine of this embodiment is used in the following way and its working principle is as follows:

[0043] In the horizontal tensile testing machine of this embodiment, the moving support body 3 can be controlled to move along the tensile guide rail 2 by controlling the operation of the displacement drive motor 41. When it is necessary to position the moving support body 3 at a suitable position on the tensile guide rail 2, this can be achieved by "controlling the upper clamping block 31 at the clamping part of the moving support body 3 to press down, and the upper clamping block 31 and the lower clamping block 32 cooperate with each other to clamp the tensile guide rail 2".

[0044] When a tensile test is required on a specimen, the main control system 6 controls the moving bearing 3 to move along the tensile guide rail 2 to the appropriate position, and then controls the upper clamping block 31 to move and clamp the tensile guide rail 2, so that the moving bearing 3 is positioned and locked on the tensile guide rail 2. Then, the clamp 7 is used to clamp the specimen, and then the corresponding tensile test is carried out under the action of the external tensile force application component.

[0045] The advantages of the horizontal tensile testing machine of this embodiment are:

[0046] 1) In the horizontal tensile testing machine of this embodiment, a displacement drive motor 41 is used to drive the moving bearing 3 to move its position, which is very convenient to operate.

[0047] 2) In this embodiment, the movable bearing 3 of the horizontal tensile testing machine can be positioned and locked at any position of the tensile guide rail 2, thereby achieving stepless positioning and locking, and can adapt to specimens of various lengths and specifications.

[0048] It should be noted that in this embodiment, the shift drive motor 41 is a servo motor, so the speed can be set arbitrarily. This is beneficial for accurately controlling the moving speed of the moving carrier 3, and the speed of the test space can be adjusted arbitrarily, which greatly improves the test efficiency.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
