Description

Technical Field

[0001] The present invention relates to the technical field related to the manufacture of hydraulic power components, and particularly to a test bench for manufacturing hydraulic power components. Background Technique

[0002] The function of the power component is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. It refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and piston pumps. Hydraulic pumps, gear pumps, vane pumps, and piston pumps all belong to hydraulic power components. After the hydraulic power components are produced, they need to be placed on the test bench for testing to ensure the quality of the hydraulic power components.

[0003] To improve the performance of the test bench for manufacturing hydraulic power components, various test benches for manufacturing hydraulic power components have been proposed on the market. For example, a test bench for manufacturing hydraulic power components with the authorized announcement number CN108412843A includes a test bench. Support rods are welded at both ends of the test bench. The other ends of the support rods are fixed with adjusting plates through rivets, and chutes are provided on the adjusting plates. A sliding rod is arranged inside the chutes. The top of the sliding rod is fixedly installed with a mounting frame through screws, and a push rod motor is installed at the top of the mounting frame through rivets. The output end of the push rod motor is connected with a push rod, and the top of the push rod is installed with an operation frame through screws. During use, the mounting frame can be manually pulled, and then the position of the mounting frame can be adjusted in the direction of the chute, which is convenient for adjusting the position of the operation frame and facilitating the lighting operation of the operation frame at different positions. Moreover, a support plate is provided at the bottom of the sliding rod, and the support plate is located inside the chute. While supporting the mounting frame, the support plate can also limit the sliding rod from leaving the chute, avoiding the collapse of the mounting frame and ensuring the feasibility of the equipment. However, the existing test benches for manufacturing hydraulic power components still have the following problems;

[0004] 1. When fixing the power component through the fixing structure, due to the uneven shapes of the tops of most power components, when using a general fixing structure, only the top part of the power component can be fixed, which is not convenient for fixing the power component with an uneven top, and the position of the fixing structure is fixed, making it inconvenient to fix power components at different positions;

[0005] 2. During the detection test, when the power component works, it generates a large amount of noise, which affects the physical and mental health of the staff;

[0006] 3. The temperature detector is fixed and not convenient for detecting the temperature changes at different positions of the power component. Therefore, we propose a test bench for manufacturing hydraulic power components to facilitate solving the problems mentioned above. Summary of the Invention

[0042] Thermometer 21, which is located at the front side of the power member 18, and the left side of the thermometer 21 is fixedly connected to the right side of the electric telescopic rod 20;

[0043] A top plate 23, the lower surface of which is welded to the upper surface of the thin metal rod 22, and the right end of the top plate 23 is threadedly connected to an extruded rod 24 having an I-shaped longitudinal section;

[0044] like Figure 1 ,Figure 2 and Figure 4 In Figure 2 and Figure 4 , the first conveying ring 6 is arranged at equal intervals inside the water tank 4, and a second conveying ring 25 is arranged inside the first conveying ring 6. The second conveying ring 25 is connected to the second conveying ring 25 through a branch pipe 7. By the first conveying ring 6 and the second conveying ring 25 arranged at equal intervals, the heat exchange efficiency is improved, and the temperature of the cooling water inside the water tank 4 is quickly reduced.

[0045] such as Figure 1 and Figure 2 In Figure 1 and Figure 2 , the inside of the sound insulation box 12 is of a hollow structure, and both the left and right ends of the sound insulation box 12 are communicated with a second horizontal pipe 11, which is convenient for water to flow inside the sound insulation box 12 with a hollow structure. A rubber sealing ring 13 is adhesively connected to the lower surface of the sound insulation box 12, and the rubber sealing ring 13 is snap-fitted on the top end of the mounting plate 15. The sound insulation effect of the sound insulation box 12 is increased through the rubber sealing ring 13.

[0046] such as Figure 1 、 Figure 2 and Figure 6 In Figure 1 , Figure 2 and Figure 6 , the fixing mechanism 17 includes a cross plate 1701, a screw rod 1702, a metal hole plate 1703 and a pressing needle 1704. The cross plate 1701 is slidably installed at the top end of the side frame 16. The inside of the cross plate 1701 is threadedly connected with a screw rod 1702 with a bottom longitudinal section in a "T" shape. The bottom end of the screw rod 1702 is rotatably connected to the top end of the metal hole plate 1703. The inside of the metal hole plate 1703 is threadedly connected with a pressing needle 1704. The power member 18 is fixed by using the fixing mechanism 17.

[0047] such as Figure 3 and Figure 5 In Figure 3 and Figure 5 , the adjusting block 19 is fixed to the front end of the side frame 16 by screws. The cross section of the adjusting block 19 is in an "L" shape, which is convenient for moving the adjusting block 19 on the side frame 16.

[0048] such as Figure 2 In Figure 2 , the extrusion rods 24 are symmetrically arranged about the horizontal center line of the top plate 23, and the sound insulation box 12 is fixed inside the top plate 23 through the extrusion rods 24. The sound insulation box 12 is fixed inside the top plate 23 by using 2 groups of symmetrically arranged extrusion rods 24.

[0049] When using the test bench for manufacturing hydraulic power components, move the device through the universal wheels installed on the lower surface of the test installation frame 1, and move the device to the destination. First, such as Figure 1 、 Figure 2 and Figure 3As shown, place the power component 18 on the mounting plate 15. The power component 18 is located at the rear side of the temperature detector 21. According to the shape of the top end of the power component 18, remove the screws used to connect the cross plate 1701 and the side frame 16, and then slide the cross plate 1701 on the top end of the side frame 16 to adjust the positions of the adjusting screw 1702, the metal orifice plate 1703, and the pressing needle 1704 above the power component 18. Since the connection method between the pressing needle 1704 and the metal orifice plate 1703 is a threaded connection, as Figure 6 shown, mounting holes are evenly formed inside the metal orifice plate 1703. Select a mounting hole at a suitable position on the metal orifice plate 1703 and thread-connect the pressing needle 1704 into the selected mounting hole. Since the connection method between the screw rod 1702 and the cross plate 1701 is a threaded connection, then manually rotate the screw rod 1702 clockwise. As the screw rod 1702 rotates clockwise, the metal orifice plate 1703 and the pressing needle 1704 move downward, thereby fixing the power component 18 by using the fixing mechanism 17 composed of the cross plate 1701, the screw rod 1702, the metal orifice plate 1703, and the pressing needle 1704, and fixing the power component 18 on the mounting plate 15;

[0050] As Figure 1 shown, a rubber ring is arranged inside the mounting plate 15. Pass the electric wire of the power component 18 through the rubber ring arranged inside the mounting plate 15. The outer side surface of the rubber ring is closely attached to the outer side surface of the electric wire of the power component 18. Seal the electric wire outlet through the rubber ring to improve the noise reduction effect;

[0051] Then remove the Figure 3 screws used to connect the adjusting block 19 and the side frame 16, and then slide the adjusting block 19 inside the side frame 16. The electric telescopic rod 20 is equipped with a built-in power storage structure. The change in the length of the electric telescopic rod 20 changes the position of the temperature detector 21, and further adjusts the position of the temperature detector 21 on the power component 18 to test the temperatures at different positions on the power component 18 and understand the temperature changes at different positions on the power component 18;

[0052] Then the staff rotates the extrusion rod 24 counterclockwise so that the extrusion rod 24 leaves the sound insulation box 12 inside the top plate 23, and then moves the sound insulation box 12 downward. As the sound insulation box 12 moves downward, the second cross pipes 11 at both ends of the sound insulation box 12 move downward, and the hose 10 retracts, so that the rubber sealing ring 13 adhesively connected to the lower surface of the sound insulation box 12 is stuck on the top end of the mounting plate 15, thereby forming a noise reduction space between the sound insulation box 12 and the mounting plate 15;

[0053] Turn on the water pump 3 fixed above the receiving plate 2. The input end of the water pump 3 is connected to the left end of the water tank 4. The output end of the water pump 3 is connected to the sound insulation box 12 through the first horizontal pipe 9, the hose 10 and the second horizontal pipe 11. Under the action of the water pump 3, the cooling water inside the water tank 4 flows through the first horizontal pipe 9, the hose 10, and the second horizontal pipe 11 into the interior of the sound insulation box 12 with a hollow structure inside. The cooling water inside the sound insulation box 12 makes the temperature inside the sound insulation box 12 approximately the same as the outside temperature, avoiding the heat generated when the power component 18 works from increasing the temperature of the internal environment of the sound insulation box 12 and affecting the temperature detection effect when the power component 18 works;

[0054] Use the thermometer 26 inside the sound insulation box 12 to detect the temperature of the internal environment of the sound insulation box 12. The water after heat exchange flows through the second horizontal pipe 11 at the right end of the sound insulation box 12 into the hose 10, and then flows back into the water tank 4 through the first horizontal pipe 9 again;

[0055] Turn on Figure 2 the micro-refrigerator 8 in, and the micro-refrigerator 8 delivers cold air into the receiving box 5 at the rear end inside the water tank 4. The receiving box 5 is connected to the first delivery ring 6 and the second delivery ring 25 through the branch pipe 7. The second delivery ring 25 is connected to the second delivery ring 25 through the branch pipe 7. The first delivery ring 6 is connected to the first delivery ring 6 through the branch pipe 7. The cold air flows through the equally spaced first delivery ring 6 and the second delivery ring 25 to the receiving box 5 at the front end inside the water tank 4. The equally spaced first delivery ring 6 and the second delivery ring 25 improve the heat exchange effect. The gas after heat exchange flows out from the front end of the receiving box 5. The cold air reduces the temperature inside the water tank 4, thereby reducing the temperature of the water inside the water tank 4. The above completes a series of operations of the test bench for manufacturing the hydraulic power component. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.

[0056] The standard parts used in the present invention can all be purchased from the market.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
