Description

Technical Field

[0001] This utility model relates to the field of bending testing machine technology, specifically a gas hose swing bending testing machine. Background Technology

[0002] The principle of the gas hose swing bending tester is to simulate the swing bending condition of the gas hose in actual use and test its performance and quality. Generally, it is powered by a motor, and the speed and torque are adjusted by a reducer. Then, the rotational motion of the motor is converted into linear reciprocating motion through a linkage, cam and other mechanisms. The clamp connected to the transmission mechanism will drive one end of the gas hose to swing back and forth, so that the hose bends around a specific center or axis. The bending angle, frequency and speed can be precisely controlled. For example, according to the standard requirements, one end of the hose can swing back and forth in both directions at a certain angle (such as 30° on one side).

[0003] Since gas hoses come in various diameters, when performing swing bending tests on gas hoses of different diameters, it is necessary to use corresponding clamps to hold and fix the gas hoses. Changing the clamps takes up a lot of working time. Therefore, in order to further simplify the clamp changing steps and improve the switching efficiency of tests on gas hoses of different specifications, a gas hose swing bending test machine is provided.

[0035] Please see Figures 1-5 In this embodiment of the present invention, a gas hose swing bending tester includes a bending tester 1 consisting of a worktable 101, a reciprocating drive structure 102, a swing arm 103, a slide rail 104, and a manual slide table 105.

A clamping assembly 2 is installed on the end face of the manual slide table 105. The clamping assembly 2 is used to clamp and fix gas hoses 3 of different diameters.

[0036] The clamping assembly 2 includes an adjustable positioning unit, a clamping unit, and a positioning unit. The adjustable positioning unit is used to match gas hoses 3 of different diameters to achieve positioning and placement of gas hoses 3 of different diameters. The clamping unit cooperates with the adjustable positioning unit to clamp and fix the gas hoses 3. The positioning unit is used to achieve rotation locking of the adjustable positioning unit.

[0037] The adjustable positioning unit includes a fixed plate 201, a fixed arm 202, a rotating seat 205, and a clamping groove 206;

[0038] There are two fixed arms 202. The two fixed arms 202 are symmetrically fixed to one end of the fixed plate 201 along the vertical direction. The fixed plate 201 is fixed to one end of the manual slide table 105 by bolts.

[0039] The rotating seat 205 is rotatably connected between the two fixed arms 202. Multiple clamping slots 206 are provided. The multiple clamping slots 206 are evenly distributed along the circumferential direction on the top of the rotating seat 205, and the clamping slots 206 completely penetrate the bottom and outer side of the rotating seat 205.

[0040] The inner wall width of the multiple clamping grooves 206 decreases sequentially to match gas hoses 3 of different diameters;

[0041] The clamping unit includes a movable groove 207, an arc-shaped rail groove 208, a rotating clamping block 210, an arc-shaped push plate 211, a fixed side plate 212, and a W-shaped spring piece 213;

[0042] The movable groove 207 is opened inside the rotating seat 205 and located on one side of the clamping groove 206, and the arc-shaped rail groove 208 is symmetrically opened at the upper and lower ends of the inner wall of the movable groove 207.

[0043] The rotating clamping block 210 is rotatably connected to the inner side of the rotating seat 205, and the side of the rotating clamping block 210 away from the rotation point extends through the clamping groove 206 to the inner side of the movable groove 207. The rotating clamping block 210 is used to clamp and fix the 3 placed inside the clamping groove 206.

[0044] The arc-shaped push plate 211 is slidably connected to the inner side of the arc-shaped rail groove 208, and the inner wall of the arc-shaped push plate 211 is attached to the outer side of the rotating clamping block 210 to limit the rotation of the rotating clamping block 210.

[0045] The fixed side plate 212 is fixed to the inner middle of the arc-shaped push plate 211 and extends to the inner side of the movable groove 207. The W-shaped spring piece 213 is distributed on the inner side of the movable groove 207, and the two ends of the W-shaped spring piece 213 are respectively attached to the fixed side plate 212 and the inner wall of the movable groove 207. The W-shaped spring piece 213 is used to provide the fixed side plate 212 and the arc-shaped push plate 211 as a whole with a thrust toward the rotating clamping block 210.

[0046] The bending testing machine 1 also includes a threaded connection seat 106, an L-shaped seat 107, and a limiting roller 108;

[0047] The threaded connector 106 and the L-shaped connector 107 are fixed to the top of the worktable 101, and the threaded connector 106 is distributed between the reciprocating drive structure 102 and the L-shaped connector 107.

[0048] Two limiting rollers 108 are provided, and the two limiting rollers 108 are symmetrically slidably installed on the end face of the vertical part of the L-shaped seat 107 and located in the area above the threaded connection seat 106;

[0049] The center line of the threaded connection seat 106 coincides with the center line of the symmetry of the two limiting roller shafts 108 and the center line of the clamping groove 206 corresponding to the gas hose 3 to be tested.

[0050] In this embodiment: when the bending testing machine 1 tests the gas hose 3, the installation operation of the gas hose 3 is as follows:

[0051] First, release the rotation lock of the positioning unit on the rotating seat 205, then rotate and adjust the rotating seat 205 so that the clamping groove 206 on the rotating seat 205 that matches the outer diameter of the gas hose 3 to be tested rotates to be aligned with the threaded connection seat 106. Then, lock the rotating seat 205 again through the positioning unit.

[0052] Then, manually push the arc-shaped push plate 211 away from the rotating clamping block 210. The arc-shaped push plate 211 further squeezes the W-shaped spring sheet 213 to deform and shrink through the fixed side plate 212. When the arc-shaped push plate 211 is completely out of contact with the rotating clamping block 210, the limit on the rotating clamping block 210 is released. At this time, the rotating clamping block 210 is rotated open, thereby releasing the blockage of the clamping groove 206.

[0053] Next, the bottom end of the gas hose 3 is threaded to the threaded connector 106 (it should be noted that the gas hose 3 end is equipped with a corresponding threaded connector cap). Then, the gas hose 3 passes through the middle area of ​​the two limiting rollers 108 and the clamping groove 206 in sequence. Then, the rotating clamping block 210 is rotated to close, thereby sealing the opening of the clamping groove 206 and clamping and fixing the gas hose 3 (it should be noted that during this process, the arc-shaped push plate 211 should be pushed first to avoid it blocking the closing of the rotating clamping block 210. After the rotating clamping block 210 is closed, the push of the arc-shaped push plate 211 is released. At this time, the arc-shaped push plate 211 will automatically reset under the elastic force of the W-shaped spring 213, thereby limiting and locking the rotating clamping block 210).

[0054] Then, the reciprocating drive structure 102 can be started. The reciprocating drive structure 102 drives the swing arm 103 to swing back and forth, which can realize the swing bending test of the gas pipeline 3. (It should be noted that the reciprocating drive structure 102, slide rail 104, manual slide table 105, threaded connection seat 106, L-shaped seat 107, and limiting roller 108 are all conventional structures of existing bending testing machines. The manual slide table 105 is adjusted up and down relative to the slide rail 104 to match gas pipelines 3 of different lengths. The two limiting rollers 108 can be adjusted and fixed horizontally to provide limiting assistance for the bending of the gas pipeline 3. Its operating principle is the same as that of common bending testing machines on the market, and it will not be described in detail here.)

[0055] Please refer to this carefully. Figures 1-5 The positioning unit includes a connecting block 203, a locking bolt 204, and a positioning hole 209;

[0056] The number of positioning holes 209 matches the number of clamping slots 206, and multiple positioning holes 209 and multiple clamping slots 206 are distributed alternately along the circumference on the top of the rotating seat 205;

[0057] The connecting block 203 is fixed to one side of the upper fixed arm 202. The locking bolt 204 is threaded to the connecting block 203 and passes through a positioning hole 209 in the connecting block 203 for locking, which is used to lock the rotation of the rotating seat 205.

[0058] In this embodiment: when it is necessary to switch the clamping slot 206, first loosen the locking bolt 204 so that it moves upward relative to the connecting block 203. Finally, the locking bolt 204 is separated from the positioning hole 209. At this time, the rotating seat 205 can be rotated, thereby realizing the switching adjustment of the clamping slot 206.

[0059] When the clamping groove 206 corresponding to the gas hose 3 to be tested is vertically aligned with the threaded connection seat 106, there is a positioning hole 209 located directly below the locking bolt 204. At this time, by turning the locking bolt 204 down to insert it into the positioning hole 209, the rotating seat 205 can be locked and fixed.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
