[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The features and illustrative embodiments of various aspects of this utility model will now be described in detail. In the following detailed description, numerous specific details are set forth in order to provide a comprehensive understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it. This utility model is by no means limited to any specific arrangements and methods set forth below, but covers any improvements, substitutions, and modifications to the structure, method, and apparatus without departing from the spirit of this utility model. In the accompanying drawings and the following description, well-known structures and techniques are not shown to avoid unnecessarily obscuring this utility model.

[0026] It should be noted that, where there is no conflict, the embodiments of this utility model and the features therein can be combined with each other, and the various embodiments can be referenced and cited in turn. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Currently, when conducting multi-link valve tests on multi-angle operation of the linkages, the product needs to be fixed to different positions on the test bench with screws for testing, such as... Figure 1-5As shown, the horizontal displacement of the valve 28 causes the angle of the connecting rod 26 to change, enabling multi-angle testing of the connecting rod 26. In the test, the angle of the connecting rod 26 is defined as 0 when it is vertical. A horizontal displacement to the left of the connecting rod 26 is a positive displacement, and the angle is also positive. A horizontal displacement to the right of the connecting rod 26 is a negative displacement, and the angle is also negative. Therefore, during multi-angle testing of the connecting rod 26, the valve 28 needs to move the connecting rod 26 back and forth in both positive and negative directions to achieve multi-angle testing.

[0028] like Figure 6-7 This utility model proposes a test device for rapid angle change of a valve linkage, including a platform 21 and a fixed frame 1. The lower end of the fixed frame 1 is connected to the platform 21, and a horizontal slide table fixed frame 2 is installed on the side. The horizontal slide table fixed frame 2 has a horizontal slide rail 3 and a horizontal transmission screw 4 arranged in the horizontal direction. The bottom of the vertical slide table fixed frame 12 is provided with a first threaded groove, and first guide grooves are provided on both sides of the first threaded groove. The first threaded groove is threadedly connected to the horizontal transmission screw 4, and the first guide grooves are slidably engaged with the horizontal slide rail 3. The surface of the vertical slide table fixed frame 12 is provided with a vertical slide rail 15 and a vertical transmission screw 14. The back of the clamping device fixed frame 7 is provided with a second threaded groove, and second guide grooves are provided on both sides of the second threaded groove. The second threaded groove is threadedly connected to the vertical transmission screw 14, and the second threaded groove is slidably engaged with the vertical slide rail 15. Movable positioning shafts are provided on both sides of the clamping device fixed frame 7, and the positioning shafts are driven by cylinders provided on both sides of the clamping device fixed frame 7.

[0029] The top plate of the fixed frame 1 is provided with a connection hole, which is connected to the connecting rod 26 of the valve 28 and the electric mechanism 25 through the connection hole.

[0030] The horizontal transmission screw 4 is connected to the horizontal handle 16, and the vertical transmission screw 14 is connected to the vertical handle 11. By rotating the horizontal handle 16, the horizontal transmission screw 4 can be rotated, and the vertical sliding fixing frame 12 can move on the horizontal slide rail 3. By rotating the vertical handle 11, the vertical transmission screw 14 can be rotated, and the clamping device fixing frame 7 can slide on the vertical slide rail 15.

[0031] The horizontal transmission screw 4 is provided with a horizontal locking mechanism 17, and the vertical transmission screw 14 is provided with a vertical locking mechanism 13. The horizontal locking mechanism 17 and the vertical locking mechanism 13 have the same structure. Both the horizontal locking mechanism 17 and the vertical locking mechanism 13 include a clamping block 24 with a small gap. The clamping block 24 is sleeved on the horizontal transmission screw 4 or the vertical transmission screw 14. Threaded holes are provided on both sides of the small gap of the clamping block 24, and a locking handle 23 is provided in the threaded holes. By rotating the locking handle 23, the small gap is tightened, so that the clamping block 24 clamps the horizontal transmission screw 4 or the vertical transmission screw 14. The clamping block 24 is fixed on the horizontal slide table fixing frame 2 or the vertical slide table fixing frame 12 through the connecting block 22.

[0032] The positioning shaft is slidably mounted on both sides of the clamping device fixing frame 7 via the guide rod 5. The positioning shaft is connected to the cylinder via the button-type locking device 9. Specifically, the left positioning shaft 8 and the right positioning shaft 20 are connected to the left cylinder 9 and the right cylinder 19 respectively via the button-type locking device 9. The positioning shaft can be quickly replaced to meet different product requirements.

[0033] In addition, the device of this utility model also includes a pneumatic switch 10 installed on the stand 21. One end of the pneumatic switch 10 is connected to the cylinder and the other end is connected to an external air source. The pneumatic switch 10 controls the connection between the external air source and the cylinder.

[0034] Two positioning pins 18 are provided on the back plate of the clamping device fixing frame 7 to position the valve 28 on the clamping device fixing frame 7.

[0035] In addition, the left positioning axis 8 and the right positioning axis 20 are made of polytetrafluoroethylene to avoid damaging the product.

[0036] In use, connect the two mounting holes 27 on the valve to the positioning pins 18 on the back plate of the clamping device fixing bracket 7 to position the valve. At this time, the product installation is complete. Turn on the pneumatic switch 10. Under the action of the left cylinder 6 and the right cylinder 19, the left positioning shaft 8 and the right positioning shaft 20 move along the guide rod 5 and are precisely inserted into the inlet and outlet holes at both ends of the valve 28. The left positioning shaft 8 and the right positioning shaft 20 contact and limit the valve body hole end face of the product. When the maximum thrust of the cylinder is reached, the movement stops and the valve 28 is fixed.

[0037] Then, the connecting rod 26 assembly and the electric mechanism 25 of the valve 28 are fixed to the upper plate of the fixed frame 1 with screws. Rotating the vertical handle 11 and the horizontal handle 16 respectively drives the horizontal transmission screw 4 and the vertical transmission screw 14 to rotate. The horizontal transmission screw 4 drives the vertical slide table fixed frame 12 to move horizontally, and the vertical transmission screw 14 drives the clamping device fixed frame 7 to move vertically, thereby moving the valve up and down and left and right. When it reaches... Figure 1-5To fix the product position, rotate the locking handle 23 in the horizontal and vertical locking mechanism. Through threaded transmission, the clamping block 24 locks the transmission screw, thus fixing the product position.

[0038] This utility model valve linkage angle rapid change test device has been put into production and use, effectively solving the problems of low efficiency in multi-angle testing of valve linkages and easy damage to products due to repeated disassembly and assembly, meeting on-site production needs and ensuring product quality.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should be covered within the protection scope of this utility model.
