Description

Technical Field

[0001] This utility model relates to the field of tensile jigs, specifically a tensile strength jig structure for structural components. Background Technology

[0002] Automotive structural components are important parts of a car, including the engine, chassis, body, electrical equipment, and tires. The engine is the power unit of the car, consisting of a crankshaft and connecting rod mechanism, valve train, cooling system, fuel supply system, lubrication system, ignition system, and starting system. The chassis consists of the transmission system, running system, steering system, and braking system. The body is mounted on the chassis frame and is used for the driver and passengers or for loading cargo. The electrical equipment consists of two parts: power supply and electrical devices. The power supply includes the battery and generator, while the electrical devices include the engine's starting system, the gasoline engine's ignition system, and other electrical devices. Tires are one of the most important components of a car, directly contacting the road surface and working with the car's suspension to mitigate the impact of driving, ensuring the car's comfort and ride smoothness.

[0003] However, since most automotive structural components on the market are large-sized structural components, traditional tensile testing machines can only handle tensile tests on slender components, making testing relatively inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a structural tensile strength jig structure, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a tensile strength fixture structure for structural components, including a tension frame, a second tensioning mechanism arranged horizontally above the tension frame, and a first tensioning mechanism arranged vertically above the tension frame. Both the first and second tensioning mechanisms include a movable tension frame and a fixed tension frame. A swing groove is formed inside the tension frame below the fixed tension frame, and a moving slide groove is formed inside the tension frame below the movable tension frame. A moving lead screw is installed inside the movable tension frame, and a hydraulic cylinder is installed on the side of the movable tension frame away from the fixed tension frame. A clamping fixture is installed at the end of the hydraulic cylinder, and a clamping fixture moving frame is arranged below the clamping fixture. Locking bolts are arrayed on the upper surface of the clamping fixture.

[0006] As a further improvement of this utility model: a stop bar is installed inside the swing groove on the side close to the clamping fixture, a limit slot is opened inside the swing groove, and an L-shaped baffle is provided inside the limit slot.

[0007] As a further improvement of this utility model, a drive motor is installed at the end of the movable lead screw.

[0008] As a further embodiment of this utility model: the second tensioning mechanism is an L-shaped structural component, and a rotating shaft is installed between the second tensioning mechanism and the tensioning frame.

[0009] As a further embodiment of this utility model: the locking bolt is engaged and movably connected with the clamping fixture, and the clamping fixture is slidably connected with the clamping fixture moving frame.

[0010] As a further improvement of this utility model: the stop bar is fixedly connected to the tension frame, and the L-shaped baffle is engaged with the limiting slot.

[0011] As a further improvement of this utility model, the movable tension frame is slidably connected to the movable slide groove.

[0012] As a further improvement of this utility model: the lower end of the movable tension frame is equipped with an engaging sliding seat located outside the movable lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The first and second tensioning mechanisms, which are horizontally and vertically enclosed above the tensioning frame, can fix the workpiece to be tested in four directions. The fixed tensioning frame can swing downwards to store the workpiece, making it convenient to place the workpiece.

[0015] When subjected to lateral stretching, the second stretching mechanism can be used to apply tension, while the clamping fixture inside the first stretching mechanism can be left unlocked to provide support. Attached Figure Description

[0022] 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.

[0023] like Figure 1-5 As shown, this embodiment provides a tensile strength fixture structure for structural components, including a tension frame 1. A second tensioning mechanism 3 is horizontally arranged above the tension frame 1. The second tensioning mechanism 3 is an L-shaped structural component. A rotating shaft is installed between the second tensioning mechanism 3 and the tension frame 1. A first tensioning mechanism 2 is vertically arranged above the tension frame 1. Both the first tensioning mechanism 2 and the second tensioning mechanism 3 include: a movable tensioning frame 4 and a fixed tensioning frame 5. A swing groove 104 is formed below the fixed tensioning frame 5 inside the tension frame 1. A swing groove 104 is formed below the movable tensioning frame 4 inside the tension frame 1. The movable slide 101 is slidably connected to the movable tension frame 4. The movable tension frame 4 is equipped with a movable lead screw 102. A hydraulic cylinder 402 is installed on the side of the movable tension frame 4 away from the fixed tension frame 5. A clamping fixture 401 is installed at the end of the hydraulic cylinder 402. A clamping fixture moving frame 403 is provided below the clamping fixture 401. The clamping fixture 401 and the clamping fixture moving frame 403 are slidably connected. Locking bolts 404 are arrayed on the upper surface of the clamping fixture 401. The locking bolts 404 are engaged and movably connected with the clamping fixture 401.

[0024] like Figure 2-4 As shown, in this embodiment, a stop bar 107 is installed inside the swing groove 104 on the side near the clamping fixture 401. The stop bar 107 is fixedly connected to the tension frame 1. A limit slot 105 is opened inside the swing groove 104. An L-shaped baffle 106 is provided inside the limit slot 105. An engaging sliding seat is installed at the lower end of the movable tension frame 4 on the outside of the moving lead screw 102. A drive motor 103 is installed at the end of the moving lead screw 102. The L-shaped baffle 106 is engaged with the limit slot 105.

[0025] The working principle of this utility model is as follows: The first stretching mechanism 2 and the second stretching mechanism 3, which are horizontally and vertically enclosed above the stretching frame 1, can fix the workpiece to be tested in four directions. Before installation, the moving stretching frame 4 inside the first stretching mechanism 2 and the second stretching mechanism 3 is adjusted to the end position of the moving slide 101 by controlling the rotation of the moving screw 102 with the drive motor 103. Then, the workpiece to be tested is placed above the stretching frame 1. The adjustment of the two fixed stretching frames 5 is controlled by the required stretching direction. The L-shaped baffle 106 is pulled out from the inside of the limiting slot 105, and the fixed stretching frame 5 is moved inside the swing groove 104 by the rotating shaft. After rotating the fixed tension frame 5 against the end of the stop bar 107, the L-shaped baffle 106 is inserted into the limiting slot 105 again for limiting. The workpiece is placed in the clamping fixture 401 inside the fixed tension frame 5, and the locking bolt 404 is controlled to clamp the workpiece downward. Then, the movable tension frame 4 is moved to the other end of the workpiece, and the clamping fixture 401 on the movable tension frame 4 is fixed to the workpiece. During stretching, the hydraulic cylinder 402 is used to control the clamping fixture moving frame 403 to stretch. The clamping fixture moving frame 403 set below the clamping fixture 401 can serve as a limiting support, so it can handle the stretching test of large-sized workpieces.
