Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection technology, specifically a tensile testing machine for workpiece inspection. Background Technology

[0002] In industrial production, the tensile testing machine for workpiece inspection, also known as the universal testing machine, is an instrument used to test the mechanical properties of materials. It is mainly used to measure the mechanical properties of materials, such as key indicators like strength, toughness, and elastic modulus. It is widely used in tensile, compression, bending, and shear tests on various materials such as plastics, rubber, and metals.

[0003] Currently, existing tensile testing machines for workpiece inspection typically use two jaws to hold the workpiece in a vertical position. However, considering that the vertical placement of the workpiece is usually done manually, improper operation may lead to misalignment before fixing the workpiece, causing it to shift or tilt during testing, affecting the accuracy of subsequent test results and hindering the equipment from achieving high-precision testing. Therefore, a new tensile testing machine for workpiece inspection is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a tensile testing machine for workpiece inspection, so as to solve the problem mentioned in the background art that the accuracy of the test structure is affected when the workpiece is placed crookedly during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tensile testing machine for workpiece inspection includes a testing table. Side guide rods are fixedly connected to the top left and right sides of the testing table. An upper clamp body is fixedly connected to the top of each side guide rod. A conical block is fixedly connected to the middle of the bottom end of the upper clamp body. Side guide rails are fixedly connected to the bottom left and right sides of the conical block. A first hydraulic telescopic rod is fixedly installed on both sides of the conical block.

A lower slide plate is fixedly connected to the bottom end of the transition block. Clamping openings are provided on opposite sides of the two lower slide plates. Limiting blocks that slide together with the side guide rails are fixedly connected to both the front and rear ends of the upper slide plate.

[0007] Preferably, a lower clamp body is provided directly below the upper clamp body, with the jaws of the lower clamp body facing upwards. Trapezoidal screws are threaded to both sides of the lower clamp body. The upper end of the trapezoidal screw is rotatably connected to the upper clamp body, and the lower end of the trapezoidal screw is rotatably connected to the testing table. The lower clamp body and the side guide rod are slidably connected together.

[0008] Preferably, inclined guide rails are fixedly connected to both the left and right ends of the middle jaw of the conical block, and jaw blocks are slidably connected to the opposite sides of the two inclined guide rails. A second hydraulic telescopic rod is fixedly installed at the upper position inside the middle jaw of the conical block, and the movable end of the second hydraulic telescopic rod extends into the square groove structure provided at one end of the two jaw blocks.

[0009] Preferably, a guide post is slidably connected to the middle of the limiting block, a spring is sleeved on one side of the guide post, one end of the spring is fixedly connected to the inner side of the side guide rail, the other end of the spring is fixedly connected to the limiting block, and the guide post is fixedly installed on the inner side of the side guide rail.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A tensile testing machine for workpiece inspection includes a testing table 1. Side guide rods 2 are fixedly connected to the top left and right sides of the testing table 1. An upper clamp body 3 is fixedly connected to the top of the side guide rods 2. A conical block 4 is fixedly connected to the middle of the bottom end of the upper clamp body 3. Side guide rails 5 are fixedly connected to the bottom left and right sides of the conical block 4. A first hydraulic telescopic rod 6 is fixedly installed on the left and right sides of the conical block 4. The movable end of the first hydraulic telescopic rod 6 extends into the interior of the conical block 4 and is fixedly connected to a push block 7. An upper slide plate 8 is fixedly connected to the bottom end of the push block 7. A transition block 19 is fixedly connected to the bottom end of the upper slide plate 8. A lower slide plate 9 is fixedly connected to the bottom end of the transition block 19. A clamping opening 10 is opened on the opposite side of the two lower slide plates 9. A limiting block 11 that slides together with the side guide rails 5 is fixedly connected to both the front and rear ends of the upper slide plate 8.

[0021] like Figure 1As shown, a lower clamp body 17 is located directly below the upper clamp body 3, with the jaws of the lower clamp body 17 facing upwards. Trapezoidal screws 18 are threaded onto both sides of the lower clamp body 17. The upper end of the trapezoidal screws 18 is rotatably connected to the upper clamp body 3, and the lower end is rotatably connected to the testing table 1. The lower clamp body 17 is slidably connected to the side guide rods 2. The lower clamp body 17 is height-adjustable, facilitating the application of tension to the workpiece and enabling normal testing. Inclined guide rails 14 are fixedly connected to both ends of the middle jaw of the conical block 4. Clamping blocks 15 are slidably connected to opposite sides of the two inclined guide rails 14. A second hydraulic telescopic rod 16 is fixedly installed above the middle jaw of the conical block 4, with its movable end extending to both sides. In the square groove structure at one end of the clamp block 15, when the workpiece to be measured is placed vertically in place, the second hydraulic telescopic rod 16 can drive the clamp block 15 to tilt and slide. The middle of the limiting block 11 is slidably connected to the guide post 12. A spring 13 is sleeved on one side of the guide post 12. One end of the spring 13 is fixedly connected to the inner side of the side guide rail 5, and the other end of the spring 13 is fixedly connected to the limiting block 11. The guide post 12 is fixedly installed on the inner side of the side guide rail 5. When the upper slide plate 8 moves horizontally, the guide post 12 and the limiting block 11 mainly play a guiding and auxiliary role. At the same time, during the movement of the upper slide plate 8, the limiting block 11 will reciprocate to compress the spring 13, so that it can rebound and store force on the limiting block 11, so that the subsequent reciprocating movement can be smoothly realized.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper slide plate 8, the adapter block 19, and the lower slide plate 9 are connected to form a "Z"-shaped structure. The clamping opening 10 is set in a "V"-shaped structure. The top surface of the upper slide plate 8 and the bottom surface of the conical block 4 are fitted together. The push block 7 is set vertically between the upper slide plate 8 and the upper slide plate 8. The push block 7 extends to the inside of the conical block 4 and slides together with the conical block 4. The clamping opening 10 is set in a "V"-shaped structure, which can better facilitate the lower slide plate 9 to use the clamping force to assist in correcting the deviation of the workpiece to be measured.

[0023] Workflow: When the detection setup of this utility model is started, it is necessary to ensure that both the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 16 are connected to the hydraulic drive system. Simultaneously, the trapezoidal lead screw 18 is mainly controlled by the drive motor inside the detection table 1. During industrial production and processing, when using this workpiece testing tensile testing machine to perform tensile testing on a workpiece, first align the workpiece to be tested with the inner side of the middle jaw of the upper clamp body 3, and vertically place it into the inner side of the upper jaw. During this vertical placement, under the connection and constraint of the conical block 4 and the side guide rail 5, the two first hydraulic telescopic rods 6 are simultaneously activated, reciprocatingly pushing the push block 7 towards the middle position of the conical block 4. The push block 7 will move the upper slide plate 8, the adapter block 19, and the lower slide plate 9 in the same direction. During this reciprocating movement, the lower slide plate 9 will pass through the clamp 10 and the workpiece to be placed vertically... The workpiece is brought into contact with the hydraulic system for auxiliary correction, ensuring it remains upright during placement. Then, the second hydraulic telescopic rod 16 is activated, simultaneously pushing down the two clamping blocks 15. Under the inclined guidance of the inclined guide rail 14, the two clamping blocks 15 slide along the inclined groove on the inclined surface of the guide rail 14, changing the distance between them and thus clamping and fixing the workpiece. Next, the two drive motors inside the testing table 1 are activated, rotating the two trapezoidal lead screws 18. The lower clamping body 17 is then subjected to force and moves upward. Once in position, and the lower end of the workpiece abuts the bottom of the middle jaw of the lower clamping body 17, the lower end of the workpiece is clamped and fixed using the same clamping and fixing method as the upper clamping body 3, facilitating subsequent tensile testing by applying tension to the workpiece.
