Description

Technical Field

[0001] The utility model relates to the field of testing devices, in particular to a flange compression limit testing device. Background Art

[0002] Flange is an important component used to connect pipes, valves, pumps and other equipment. It is usually composed of a round metal disc with a certain thickness and holes, which is used to install bolts to fix it to other equipment. Flanges are widely used in the industrial field, and their functions include connection, sealing and support. After the flange is produced, in order to ensure that its quality meets the standards, it is usually necessary to conduct a compressive limit test.

[0003] The existing flange compressive limit test is to put the flange on the fixed roller on the test bench and then squeeze the flange through a press to test the flange's compressive limit. However, since the fixed roller cannot limit the flange, when the flange is squeezed and deformed, it may detach from the fixed roller, affecting the accuracy of the flange compressive limit test.

[0004] Therefore, a flange compressive limit testing device has been developed that can limit the position of the flange to prevent the flange from being separated from the extension roller after deformation, which affects the accuracy of the test. Utility Model Content

[0005] In order to overcome the disadvantage of the existing flange compression limit test that when the flange is squeezed and deformed, it may detach from the fixed roller, resulting in affecting the accuracy of the flange compression limit test, the utility model provides a flange compression limit test device which can limit the position of the flange to prevent the flange from detaching from the extension roller after deformation, thereby affecting the accuracy of the test.

[0006] The technical solution is as follows: A flange compressive limit test device includes a base, an arc seat, a frame wheel, a tail frame, an extension roller, a support plate, a first spring and a locking mechanism. The upper side of the base is connected to the arc seat, and the left and right parts of the arc seat are rotatably connected to the frame wheel. The upper side of the base is connected to the tail frame, and the tail frame is located at the rear side of the arc seat. The upper part of the tail frame is rotatably connected to the extension roller, and a plurality of support plates are slidably connected to the extension roller. Two front and rear first springs are connected between the support plates and the extension rollers, and a locking mechanism that can lock the flange is provided on the base.

[0007] Optionally, the locking mechanism includes a motor, a screw, a pressure device and a cover. The motor is connected to the upper left rear side of the base, the screw is connected to the motor output shaft, the pressure device is threadedly connected to the screw, the left part of the pressure device is slidably connected to the base, and the lower part of the pressure device is slidably connected to the cover.

[0008] Optionally, a limit block is provided on the upper side of the screw rod.

[0009] Optionally, a fixing mechanism is also included, which includes an end seat, a second spring and a pressure plate. The end seat is slidably connected to the upper middle side of the base, and the end seat is also slidably connected to the tail frame. The upper rear side of the end seat is connected to the pressure plate through the second spring.

[0010] Optionally, an anti-slip sheet is provided on the pressure plate.

[0011] Optionally, a brake pad is also included, and the lower part of the end seat is connected to the brake pad.

[0012] The beneficial effects of the utility model are: 1. The utility model covers the outside of the flange with a cover, and then allows the presser to continue to move downward on the cover, so that the presser squeezes the flange, thereby achieving the effect of limiting the position of the flange and preventing the flange from being separated from the extension roller after deformation, which affects the accuracy of the test.

[0013] 2. The utility model uses the force of the second spring to press the pressure plate against the flange. When the end seat moves backward, it drives the brake pad to move backward, so that the brake pad contacts the flange, thereby fixing the flange and preventing the flange from rotating and affecting the detection accuracy.

DETAILED DESCRIPTION

[0019] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0020] A flange compressive limit test device, such as Figure 1 and Figure 2As shown, it includes a base 1, an arc seat 2, a frame wheel 3, a tail frame 4, an extension roller 5, a support plate 6, a first spring 60 and a locking mechanism 7. The arc seat 2 is connected to the upper side of the base 1, and the left and right parts of the arc seat 2 are rotatably connected to the frame wheel 3. The upper side of the base 1 is connected to the tail frame 4, and the tail frame 4 is located at the rear side of the arc seat 2. The upper part of the tail frame 4 is rotatably connected to the extension roller 5, and three support plates 6 are slidably connected to the extension roller 5. Two front and rear first springs 60 are connected between the support plates 6 and the extension roller 5, and a locking mechanism 7 is provided on the base 1.

[0021] like Figure 1 and Figure 3 As shown, the locking mechanism 7 includes a motor 71, a screw rod 72, a pressure device 73 and a cover 74. The motor 71 is connected to the upper left rear side of the base 1, the screw rod 72 is connected to the output shaft of the motor 71, the pressure device 73 is threadedly connected to the screw rod 72, a limit block is provided on the upper side of the screw rod 72 to facilitate limiting the pressure device 73, the left part of the pressure device 73 is slidably connected to the base 1, and the lower part of the pressure device 73 is slidably connected to the cover 74.

[0022] When using the utility model, first place the base 1 in the compression limit test area of ​​the flange 0, then put the flange 0 in the extension roller 5 on the tail frame 4, so that the flange 0 squeezes the support plate 6 for recovery, and the support plate 6 fixes the flange 0 through the action of the first spring 60, and the lower side of the flange 0 is supported by the frame wheel 3 on the arc seat 2, and then the motor 71 is started to drive the screw rod 72 to rotate, so that the pressure device 73 moves downward, and drives the cover 74 to move downward, so that the cover 74 covers the outside of the flange 0, and then the pressure device 73 continues to move downward on the cover 74, so that the pressure device 73 squeezes the flange 0 to test the compression limit capacity of the flange 0, thereby playing a role in limiting the position of the flange 0 and preventing the flange 0 from being separated from the extension roller 5 after deformation, which affects the accuracy of the test.

The brake pad 84 is connected to the lower part of the end seat 81.

[0024] By using the fixing mechanism 8 of the device, the flange 0 can be fixed. After the flange 0 is fixed on the extension roller 5, the end seat 81 is pushed to move backward, so that the pressure plate 83 passes through the extension roller 5 and contacts the flange 0. Through the action of the second spring 82, the pressure plate 83 is pressed tightly on the flange 0. When the end seat 81 moves backward, it drives the brake pad 84 to move backward, so that the brake pad 84 contacts the flange 0, thereby fixing the flange 0 and preventing the flange 0 from rotating and affecting the detection accuracy.
