Description

Technical Field

[0001] This utility model relates to the field of tooling for testing the hardness of anchor clamp pieces, and more specifically, to a fixing tooling for testing the hardness of anchor clamp pieces. Background Technology

[0002] In bridge construction, anchor wedges are critical components, and their hardness directly affects the safety and stability of the bridge structure. Therefore, anchor wedges need to be tested for hardness (using a Rockwell hardness tester) before being put into use. Currently, the existing tooling for testing the hardness of bridge anchor wedges has the following shortcomings: On the one hand, after the traditional tooling has positioned the anchor wedge, the outer wall of the subsequent anchor wedge is in inclined contact with the detection end of the hardness testing equipment, which will lead to a large error in the hardness test value and cannot accurately reflect the true hardness of the anchor wedge. On the other hand, most existing fixed fixtures are designed for anchor clamps of a single specification, which is not very versatile and cannot effectively clamp anchor clamps of different specifications for hardness testing. In summary, the current fixtures for hardness testing of anchor clamps have the above-mentioned problems that urgently need to be solved. Utility Model Content

The angle adjustment component is mounted on the base plate and connected to a mounting plate. The fixing plate is fixed to the mounting plate; The movable plate is in contact with the surface of the mounting plate, and the movable plate is connected to the elastic limiting component set on the mounting plate; The limiting roller is movably mounted on the elastic limiting component and cooperates with the arc groove; Arc-shaped holes are respectively opened at the same position on the fixed plate and the movable plate, allowing the limiting roller to pass through.

[0005] Furthermore, the angle adjustment assembly includes a mounting rod, a screw, a guide roller, a knob, a moving block, and a connecting rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 3 As shown, a fixing fixture for testing the hardness of anchor clamp pieces includes a base plate 1, an angle adjustment assembly 2, a mounting plate 3, an arc groove 31, a fixing plate 4, a movable plate 5, an elastic limiting assembly 6, a limiting roller 7, and an arc-shaped hole 8. Angle adjustment component 2 is mounted on base plate 1 and connected to mounting plate 3; The fixing plate 4 is fixed on the mounting plate 3; The movable plate 5 is in contact with the surface of the mounting plate 3, and the movable plate 5 is connected to the elastic limiting component 6 provided on the mounting plate 3; The limiting roller 7 is movably mounted on the elastic limiting component 6 and cooperates with the arc groove 31; Arc-shaped holes 8 are respectively opened at the same position on the fixed plate 4 and the movable plate 5, allowing the limiting roller 7 to pass through.

[0013] Specific implementations of the embodiments of this utility model, such as Figure 1 As shown, the angle adjustment assembly 2 includes a mounting rod 21, a screw 22, a guide roller 23, a knob 24, a moving block 25, and a connecting rod 26. Mounting rod 21 is fixed on base plate 1, and the upper end of mounting rod 21 is hinged to mounting plate 3; The screw 22 is rotatably mounted on the base plate 1. A moving block 25 is threadedly connected to the screw 22, and a knob 24 is connected to the upper end of the screw 22. The guide roller 23 is fixed on the base plate 1, and the guide roller 23 is slidably engaged with the moving block 25; The two ends of the connecting rod 26 are respectively connected to the moving block 25 and the mounting plate 3.

[0014] Specific implementations of the embodiments of this utility model, such as Figure 1 As shown, the elastic limiting assembly 6 includes a mounting block 61, a connecting roller 62, a spring 63, and a pull handle 64. Mounting block 61 is fixed on mounting plate 3, and limit roller 7 is movably mounted on mounting block 61; The connecting roller 62 is slidably engaged with the mounting block 61. One end of the connecting roller 62 is connected to the movable plate 5, and the other end of the connecting roller 62 is provided with a handle 64. Spring 63 is sleeved on connecting roller 62, and one end of spring 63 is connected to movable plate 5, while the other end of spring 63 is connected to mounting block 61.

[0015] To further improve the fixing effect of the anchor clamps, the above-described embodiments are further optimized, such as... Figure 1 and Figure 2 As shown, a double limiting component 9 is provided on the mounting plate 3; The dual limiting assembly 9 includes a fixing block 91, an auxiliary screw 92, a circular block 93, and a handle 94. The fixing blocks 91 are symmetrically fixed on the mounting plate 3; The auxiliary screw 92 is threadedly connected to the fixed block 91, and the two ends of the auxiliary screw 92 are respectively provided with a handle 94 and a round block 93.

[0016] To reduce wear on the surface of the anchor clamping plate during clamping, the above embodiment is further optimized by providing a rubber layer on the surface of the circular block 93, the fixed plate 4, and the movable plate 5. The rubber layer is not shown in the figure.

[0017] The working process of this utility model is as follows: The initial limiting roller 7 is located in the arc groove 31 and can move along the arc groove 31 (the limiting roller 7 is higher than the arc groove 31 and can pass through the arc hole 8 on the fixed plate 4 and the movable plate 5). Then, the handle 64 is manually pulled outward to compress the spring 63. While the spring 63 is compressed, the movable plate 5 can move away from the fixed plate 4 so that the anchor clamp to be tested can be smoothly placed between the fixed plate 4 and the movable plate 5. Then, the inner side of the anchor clamp to be tested (one-third of the clamp, not shown in the figure) is fastened to the surface of the limiting roller 7 (the two are adapted and attached). At this time, the two ends of the clamp are attached to the surface of the mounting plate 3. Then, the handle 64 is released, and the spring 63 can restore its deformation and thus limit the anchor clamp between the fixed plate 4 and the movable plate 5. Then, the installation stability of the anchor clamp is further limited from the front and rear sides by the double limiting component 9. After the anchor clamp is stably clamped and positioned, the knob 24 is turned to rotate the screw 22. After the screw 22 rotates, the moving block 25 can be raised and lowered vertically. At this time, the anchor clamp after the entire mounting plate 3 is positioned can be deflected. When the outer surface of the anchor clamp is parallel to the base plate 1, the fixture can be transferred to the testing table of the hardness testing equipment for subsequent testing. At this time, the surface of the anchor clamp is perpendicular to the testing end of the hardness testing equipment, so the hardness test value is more accurate and the error is greatly reduced. The hardness testing equipment is existing technology and will not be improved. It is not shown in the figure. Specifically, the Rockwell hardness testing equipment with model number TIME6166 produced by Beijing Times Peak Technology Co., Ltd. is used. Subsequently, when the specifications of the anchor wedges requiring hardness testing change, the limiting roller 7 that is compatible with the inner wall of the new specification anchor wedge is first replaced (the replaced limiting roller 7 can also pass through the arc hole 8 and move along the inside of the arc groove 31 without being affected. In this application, the wedges to be tested are all matched with steel strands of the same diameter, so the size of the arc groove 31 remains unchanged, and the arc groove 31 simulates the steel strand). Then, the above process is repeated to carry out the hardness testing process of anchor wedges of different specifications.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
