Description

Technical Field

[0001] This utility model relates to the field of bolt testing technology, specifically a flange bolt testing fixture. Background Technology

[0002] A flange bolt is an integral bolt consisting of a hexagonal head and a flange (with a gasket and hexagonal fixing piece underneath) and a threaded rod (a cylinder with external threads). It needs to be used with a nut to fasten parts that connect two through holes. When the flange bolt connects two sets of flanges, a flange bolt testing fixture is needed to test the flange bolt in order to ensure the stability of subsequent use.

[0003] Flange bolts are mostly installed and connected with hexagonal heads. When inspecting bolts, a concave hexagonal rod needs to be fitted onto the outside of the hexagonal head before inspection. When inspecting flange bolts, it is necessary to replace the concave hexagonal rod with a matching one for the hexagonal head of different bolt widths, and then fit the corresponding concave hexagonal rod onto the outside of the hexagonal head for inspection. This reduces the efficiency of the inspection work. Therefore, a flange bolt testing fixture is proposed. Utility Model Content

[0010] Furthermore, both the pressure sensor and the cylinder are electrically connected to an external sensor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This flange bolt testing fixture uses a cylinder to move a fixed cylinder, causing the fixed groove to compress the extrusion plate, thereby fixing the bolts with a clamping plate. The distance the fixed cylinder moves with the cylinder can clamp and fix hexagonal bolts of different sizes, increasing the applicability of the fixture and improving testing efficiency.

[0013] 2. This flange bolt testing fixture uses a motor to drive the drive gear to rotate, which in turn drives the driven gear to rotate, causing the support cylinder to rotate.

[0019] 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.

[0020] Example 1:

[0021] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a flange bolt testing fixture, including a mounting frame 12 and a connecting plate 1. Four connecting brackets 2 are fixedly connected in a circumferential array on the front outer surface of the connecting plate 1. A fixing plate 3 is fixedly connected to the other end of each connecting bracket 2. A cylinder 4 is fixedly mounted on the outer surface of the connecting plate 1. A fixing cylinder 5 is fixedly connected to the output end of the cylinder 4. A fixing groove 10 is formed inside the fixing cylinder 5. A hexagonal groove is formed on the outer surface of the fixing plate 3. A first spring 8 is fixedly connected to each of the six inner walls of the hexagonal groove. A connecting plate 7 is fixedly connected to the other end of each first spring 8. A pressing plate 6 is fixedly connected to the rear side of the connecting plate 7, and a clamping plate 9 is provided on the other side of the connecting plate 7. Specifically, the cylinder 4 works, and the cylinder 4 drives the fixing cylinder 5 so that the fixing groove 10 of the fixing cylinder 5 contacts the pressing plate 6. As the cylinder 4 pushes the fixing cylinder 5, the fixing groove 10 presses multiple pressing plates 6, so that the clamping plate 9 contacts the hexagonal side of the bolt until the bolt is fixed. Then the bolt is inspected. Thus, the distance that the cylinder 4 drives the fixing cylinder 5 to move can clamp and fix hexagonal bolts of different sizes, thereby increasing the applicability of the tooling and improving the testing efficiency.

[0022] In this embodiment, a support cylinder 11 is rotatably connected to the outer surface of the mounting frame 12, and a connecting plate 1 is fixedly sleeved on the outer surface of the support cylinder 11. A motor 13 is fixedly mounted on the outer surface of the mounting frame 12, and a drive gear 15 is fixedly sleeved on the output end of the motor 13. A driven gear 14 is fixedly sleeved on the outer surface of the support cylinder 11. The outer surfaces of the drive gear 15 and the driven gear 14 are movably meshed. Specifically, the motor 13 drives the drive gear 15 to rotate, which in turn drives the driven gear 14 to rotate, causing the support cylinder 11 to rotate. The support cylinder 11 drives the connecting plate 1, which in turn causes the fixing plate 3 to rotate the fixed bolts, thereby enabling continuous detection of the bolts and further improving testing efficiency.

[0023] In this embodiment, a second spring 16 is fixedly connected to the outer surface of the connecting plate 7, and the other end of the second spring 16 is fixedly connected to the clamping plate 9. A pressure sensor 17 is fixedly installed on the outer surface of the connecting plate 7. Specifically, when the clamping plate 9 clamps the hexagonal bolt, the second spring 16 deforms and the clamping plate 9 comes into contact with the pressure sensor 17. The pressure sensor 17 senses the clamping force of the clamping plate 9, so that it can stably clamp the bolt.

[0024] In this embodiment, the fixing groove 10 is conical and the extrusion plate 6 is triangular. Specifically, through the conical fixing groove 10 and the triangular extrusion plate 6, when the fixing groove 10 corresponds to the extrusion plate 6, the fixing groove 10 can extrude the extrusion plate 6, so that the extrusion plate 6 drives the clamping plate 9 to move closer to the center.

[0025] In this embodiment, anti-slip pads are fixedly connected to the outer surfaces of multiple clamping plates 9, and anti-slip patterns are formed on the outer surfaces of the anti-slip pads. Specifically, the friction of the clamping plates 9 is increased by setting anti-slip pads and forming anti-slip patterns on the clamping plates 9.

[0026] In this embodiment, both the pressure sensor 17 and the cylinder 4 are electrically connected to an external sensor. Specifically, the pressure sensor 17 senses the value and sends the value signal to the controller, which then controls the operation of the cylinder 4.

[0027] Working principle: When using this utility model, the flange bolts are fixed by aligning the bolts with the hexagonal slots. The cylinder 4 operates, driving the fixing cylinder 5 so that the fixing slot 10 of the fixing cylinder 5 contacts the extrusion plate 6. As the cylinder 4 pushes the fixing cylinder 5, the fixing slot 10 extrudes multiple extrusion plates 6, causing the clamping plate 9 to contact the hexagonal sides of the bolt until it is fixed. The bolt is then inspected. The distance the fixing cylinder 5 moves, driven by the cylinder 4, allows for clamping and fixing of hexagonal bolts of different sizes, thus increasing the applicability of the tooling and improving testing efficiency.

[0028] During testing, the motor 13 drives the drive gear 15 to rotate, which in turn drives the driven gear 14 to rotate, causing the support cylinder 11 to rotate. The support cylinder 11 then drives the connecting plate 1, which in turn drives the fixed plate 3 to rotate the fixed bolts. This enables continuous testing of the bolts and further improves testing efficiency.
