Description

Technical Field

[0001] This invention belongs to the field of hydraulic motor testing technology, and particularly relates to a convenient hydraulic motor rapid assembly and testing device. Background Technology

[0002] Hydraulic motors are components that convert hydraulic energy into mechanical energy. They are widely used in injection molding machinery, ships, hoists, engineering machinery, and construction machinery. The output torque of a hydraulic motor is a key performance parameter. Therefore, in the factory testing of motors, it is necessary to test the output torque and the stability of the output torque value under different working conditions.

[0003] For example, Chinese patent document (CN116398504B) describes a test platform for hydraulic motor outlet pressure fluctuation, comprising: Step S1: Adjusting the clamping positioner on the test platform to place the hydraulic motor under test on the test platform and clamp it in place using the clamping positioner; Step S2: Installing a pressure sensor on the outlet pipe of the hydraulic motor under test to measure the pressure fluctuation at the outlet of the hydraulic motor under test; Step S3: Installing a gravity load device at the end of the output shaft of the hydraulic motor under test to increase the working load of the hydraulic motor under test; Step S4: The pressure sensor measures the pressure fluctuation of the hydraulic motor under test, and the test data is collected and analyzed by a PLC controller set at the bottom of the test platform. This invention uses an adjustable clamping positioner to clamp and position hydraulic motors of different sizes under test, thus improving the applicability of the invention. However, during use, the equipment only tests the motor by adjusting the load on the motor output shaft. If the shape of the external load is different, it will also affect the output state of the hydraulic motor, resulting in poor test results. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing technologies, which rely solely on adjusting the load on the motor output shaft for testing, can lead to poor test results if the external load has a different shape, thus affecting the output state of the hydraulic motor.

The multiple fixing blocks and multiple connecting blocks are arranged relative to each other.

[0018] As a further description of the above technical solution:

[0019] A third spring is sleeved on the outer periphery of the fixed rod. The two sides of the third spring are fixedly connected to one side of the roller and the inner wall of the circular seat, respectively. An arc-shaped groove is opened on the side of the annular seat opposite to the roller.

[0020] As a further description of the above technical solution:

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, a dynamic adjustment component is used to drive the second motor to rotate the circular seat, electric push rod, rectangular block, and first cone block, thereby adjusting the usage state of the first cone block relative to multiple second cone blocks. Then, the electric push rod drives the rectangular block and the first cone block to move, causing the second cone blocks relative to the first cone block to move the horizontal plate, connecting block, and slider, thus adjusting the extension state of the slider relative to the circular seat. This allows for adjustment of the usage state of the outer contour of the circular seat. This device, through a separately configured drive unit, can produce different shapes for the overall outer contour of the circular seat, accurately simulating the complex and changing load contours faced by the hydraulic motor under test in real-world working conditions. This enables comprehensive, realistic, and controllable testing of the dynamic performance and reliability of the hydraulic motor and its drive system, significantly improving the testing compatibility and applicability of the equipment. Furthermore, this equipment does not require replacement of the physical load plate or test bench mechanical structure, greatly improving testing efficiency and flexibility while reducing testing costs.

[0028] 2. In this invention, by setting a limiting component, after the slider extension adjustment of the relative position is completed, the second motor will drive the circular seat and the annular seat to rotate. At this time, the contact state between the first cone block and the second cone block is not completely disengaged, and the roller will first disengage from the arc groove. Under the action of the annular seat, the roller will drive the fixing rod and the fixing block to fix the connecting block, thereby fixing the extension state of the slider. This prevents the slider from moving under the driving centrifugal force of the hydraulic motor under test during the test process, thus ensuring the operational stability of the equipment during the test process and helping to ensure the test accuracy of the equipment. In the process of ensuring the test accuracy of the equipment, the integration of the equipment is improved.

[0029] 3. In this invention, the resistance adjustment component enables the first motor to drive the rotating shaft, gear, ring gear, and multiple protrusions to rotate, gradually causing the arc-shaped block to move the connecting rod and damping block towards the load block. This adjusts the rotational resistance of the load end composed of the load block and the circular seat during the initial or initial startup of the load block. The device can dynamically adjust the resistance according to actual needs, allowing it to control the starting resistance in real time and accurately according to actual working conditions. This enables the device to meet the resistance testing requirements of the hydraulic motor under test in different application scenarios or during the initial startup of different loads, greatly improving the applicability of the device.

[0043] Please see Figures 1-10 The present invention provides a technical solution: a convenient hydraulic motor rapid assembly and testing device, including a test bench 1, a first mounting seat 2 and a hydraulic motor 3 to be tested are provided on one side of the top of the test bench 1, a second mounting seat 4 is provided on the side of the first mounting seat 2 away from the hydraulic motor 3 to be tested, a load fixing seat 10 is fixedly connected inside the second mounting seat 4, a circular seat 6 and a load block 11 are rotatably connected inside the load fixing seat 10, a resistance adjustment component 7 is provided on one side of the load block 11, and a dynamic adjustment component 8 and a limit component 9 are provided inside the circular seat 6.

[0044] The dynamic adjustment component 8 includes multiple sets of second springs 809 arranged in a circular array on the inner circumference of the circular base 6. A horizontal plate 807 is fixedly connected to the bottom of each second spring 809, and a second cone block 806 is fixedly connected to the top of the horizontal plate 807. An adjustment unit is provided on one side of the inclined surface of the second cone block 806. A slider 810 is fixedly connected to the center of the top of the horizontal plate 807 via a connecting block 808. The adjustment unit causes the second cone block 806 to move the connecting block 808 and the slider 810 outward from the circular base 6 to test its... The effect of different shaped loads on the circular seat 6 on the hydraulic motor 3 under test is investigated. The adjustment unit includes a second motor 801. One side of the second motor 801 is fixedly connected to the inner wall of the circular seat 6. One end of the output shaft of the second motor 801 is fixedly connected to a circular seat 802. The circular seat 802 is slidably connected inside the circular seat 6. A cavity is opened on one side of the circular seat 802, and an electric push rod 803 is installed inside the cavity. One side of the electric push rod 803 is fixedly connected to the inner wall of the circular seat 802, and one end of the output shaft of the electric push rod 803 is fixedly connected to the inner wall of the circular seat 802. A rectangular block 804 is connected and slidably connected inside the circular seat 802. The side of the rectangular block 804 away from the electric push rod 803 extends to the outside of the circular seat 802 and is fixedly connected to a first cone block 805. The inclined surface of the first cone block 805 is adapted to the inclined surface of the second cone block 806. The hydraulic motor 3 to be tested is fixedly connected to the first mounting seat 2. The bottom of the first mounting seat 2 is slidably connected to the top of the test bench 1 through the first moving module. The bottom of the second mounting seat 4 is set on the top of the test bench 1 through the second moving module. A connecting unit 5 is provided between the first mounting seat 2 and the second mounting seat 4. The bottom of the connecting unit 5 is fixedly connected to the top of the test bench 1. The circular seat 6, the load block 11 and the load fixing seat 10 are on the same axis. One side of the circular seat 6 and the load block 11 are fixedly connected to the outer wall. The load block 11 is fixedly connected to the outer periphery of the connecting unit 5. The circular seat 6 has multiple mounting slots arranged in a circular array on the side opposite to the inside of the load block 11. The connecting block 808 and the slider 810 are both slidably connected inside the mounting slots.

[0045] Detailed Implementation: First, place the test bench 1 in a suitable location. Then, have the operator install the hydraulic motor 3 to be tested onto the first mounting base 2 using external devices and bolts. The installation position of the hydraulic motor 3 can be defined by the multiple through holes in the circular array built into the first mounting base 2, so that it is as close as possible to the connecting unit 5, the second mounting base 4, and the load fixing base 10 as possible. Then, have the operator connect the oil inlet, outlet, and drain ends of the hydraulic motor 3 to the external hydraulic supply control system through the pipe structure. Finally, connect one end of the output shaft of the hydraulic motor 3 to the load block 11 through the connecting unit 5. Then, the corresponding sensors are installed at appropriate test points on the hydraulic motor 3 under test. After the hydraulic motor 3 under test is assembled and connected to the load end consisting of the load fixing seat 10, the load block 11, and the circular seat 6, oil is supplied to the hydraulic motor 3 under test through the external hydraulic supply control unit, causing the hydraulic motor 3 under test to drive the load end to rotate, so as to simulate the actual use process of the hydraulic motor 3 under test. During this process, the first motor 701 and the second motor 801 can be started as needed. The second motor 801 drives the circular seat 802, the electric push rod 803, the rectangular block 804, and the first cone block. Rotation 805 adjusts the usage state of the first cone block 805 relative to multiple second cone blocks 806. Then, the electric push rod 803 moves the rectangular block 804 and the first cone block 805. During this movement, the first cone block 805 presses against the second cone blocks 806 at a relative position, causing the second cone block 806 at that position to move the horizontal plate 807, connecting block 808, and slider 810, thus adjusting the extension state of the slider 810 relative to the circular seat 6. Similarly, the extension state of the sliders 810 around the relative positions can be gradually adjusted, thereby adjusting the usage state of the outer contour of the circular seat 6. The device can produce different shapes of the overall outer contour of the circular base 6 through a separately set drive unit, which can accurately simulate the complex and changing load contour faced by the hydraulic motor 3 under test in real working conditions. This allows for a comprehensive, realistic and controllable test of the dynamic performance, efficiency, control effect, reliability and matching of the hydraulic motor 3 and its drive system. Moreover, this device does not require replacement of the physical load plate or test bench mechanical structure, which greatly improves the testing efficiency and flexibility of the device and reduces the testing cost. The connecting unit 5 can be selected as a linkage unit with a support base according to the actual situation, and the linkage unit can be set as an elastic linkage.

[0046] The limiting component 9 includes an annular seat 901, which is fixedly connected to the outer periphery of the circular seat 802. The annular seat 901 is located on the side away from the load block 11. Multiple rollers 902 are arranged in a circular array on the side of the annular seat 901 opposite to the load block 11. A fixing rod 903 is fixedly connected to the side of the rollers 902 away from the load block 11. The other end of the fixing rod 903 extends into the mounting groove and is fixedly connected to a fixing block 905. A wear-resistant block is provided on the side of the fixing block 905 away from the fixing rod 903. The fixing block 905 is slidably connected inside the mounting groove. Multiple fixing blocks 905 and multiple connecting blocks 808 are arranged opposite to each other. A third spring 904 is sleeved on the outer periphery of the fixing rod 903. The two sides of the third spring 904 are fixedly connected to one side of the roller 902 and the inner wall of the circular seat 6, respectively. An arc-shaped groove 906 is opened on the side of the annular seat 901 opposite to the roller 902.

[0047] Detailed Implementation: The circular seat 802 drives the annular seat 901 and the arc-shaped groove 906 inside to rotate. During the process of the electric push rod 803 adjusting the position of the relative slider 810, the roller 902 at the position of the relative slider 810 and the connecting block 808 will enter the arc-shaped groove 906. At this time, the third spring 904 will drive the roller 902, the fixing rod 903 and the fixing block 905 to move, releasing the limiting and fixing state of the fixing block 905 on the connecting block 808. After the adjustment of the relative position of the slider 810 is completed, the second motor 801 will drive the circular seat 802 and the annular seat 901 to rotate. At this time, the contact state between the first cone block 805 and the second cone block 806 is not completely disengaged, and the roller 902 will first contact the... The arc-shaped groove 906 disengages, and under the action of the annular seat 901, the roller 902 drives the fixing rod 903 and the fixing block 905 to fix the connecting block 808, thereby fixing the extended state of the slider 810. This prevents the slider 810 from moving under the centrifugal force of the hydraulic motor 3 under test during the test, thus ensuring the stability of the equipment during the test and helping to ensure the test accuracy. When it is necessary to fix the positions of multiple sliders 810, the second motor 801 only needs to drive the circular seat 802 and the annular seat 901 to rotate, rotating the arc-shaped groove 906 between the two rollers 902. This improves the integration of the equipment while ensuring the test accuracy.

[0048] The resistance adjustment assembly 7 includes a first motor 701. One side of the first motor 701 is fixedly connected to the inner wall of the load fixing seat 10. One end of the output shaft of the first motor 701 is fixedly connected to a rotating shaft 702. A gear 703 is fixedly connected to the outer periphery of the rotating shaft 702. A ring gear 704 is meshed with the bottom of the gear 703. The ring gear 704 is rotatably connected inside the load fixing seat 10, and the ring gear 704 and the load block 11 are on the same axis. A plurality of protrusions 705 are arranged in a circular array on the inner periphery of the ring gear 704. A plurality of arc-shaped blocks 706 are arranged between the plurality of protrusions 705. The arc-shaped blocks 706 are far from the ring gear 704. A circular frame 710 is provided on one side of the gear 704. The circular frame 710 is fixedly connected to the inside of the load fixing seat 10. The inside of the circular frame 710 has multiple circular through holes arranged in a circular array. A connecting rod 707 is slidably connected inside the circular through holes. One end of the connecting rod 707 is fixedly connected to the outer wall of the arc block 706. The other end of the connecting rod 707 extends to the other side of the circular frame 710 and is fixedly connected to a damping block 708. The damping block 708 is slidably connected inside the load fixing seat 10. A first spring 709 is sleeved on the outer periphery of the connecting rod 707. The two sides of the first spring 709 are fixedly connected to the arc block 706 and the outer wall of the circular frame 710, respectively.

[0049] Detailed Implementation: The first motor 701 drives the rotating shaft 702 and gear 703 to rotate. Utilizing the linkage effect between gear 703 and ring gear 704, power is transmitted to ring gear 704, causing ring gear 704 to drive multiple protrusions 705 to rotate. As the protrusions 705 gradually move to the position of the arc-shaped block 706, the arc-shaped surface of the protrusion 705 will contact the outer peripheral arc-shaped surface of the arc-shaped block 706, gradually causing the arc-shaped block 706 to drive the connecting rod 707 and damping block 708 to move towards the load block 11. This adjusts the rotational resistance of the load end composed of the load block 11 and the circular seat 6 during the initial start-up or startup process of the load block 11. This device can dynamically adjust the resistance according to actual needs, enabling it to control the starting resistance in real time and accurately according to actual working conditions. This allows the device to meet the resistance testing requirements of the hydraulic motor 3 under test in different application scenarios or during the initial start-up process of different loads, greatly improving the applicability of the device.

[0050] Working Principle: In use, first place the test bench 1 in a suitable location. Then, the operator uses external devices and bolts to install the hydraulic motor 3 to be tested onto the first mounting base 2. The installation position of the hydraulic motor 3 is defined by the multiple through holes in the circular array built into the first mounting base 2, ensuring it is aligned with the connecting unit 5, the second mounting base 4, and the load fixing base 10 on the same axis. Next, the operator connects the oil inlet, outlet, and drain ends of the hydraulic motor 3 to the external hydraulic supply control system via a pipe structure. Then, one end of the output shaft of the hydraulic motor 3 is connected to the load block 11 via the connecting unit 5, and the corresponding sensors are installed at appropriate test points on the hydraulic motor 3. After assembling and connecting the hydraulic motor 3 with the load end consisting of the load fixing base 10, the load block 11, and the circular base 6, the external hydraulic supply control unit supplies oil to the hydraulic motor 3, causing it to rotate the load end, thus simulating the actual use of the hydraulic motor 3.

[0051] During this process, the first motor 701 and the second motor 801 can be started as needed. The first motor 701 drives the rotating shaft 702 and the gear 703 to rotate. By utilizing the linkage effect between the gear 703 and the ring gear 704, the power is transmitted to the ring gear 704, causing the ring gear 704 to drive multiple protrusions 705 to rotate. When the protrusions 705 gradually move to the position of the arc block 706, the arc surface of the protrusions 705 will contact the outer peripheral arc surface of the arc block 706, and gradually cause the arc block 706 to drive the connecting rod 707 and the damping block 708 to move towards the load block 11, thereby adjusting the rotational resistance of the load end composed of the load block 11 and the round seat 6 when the load block 11 is just started or during the start-up process.

[0052] The second motor 801 drives the circular base 802, electric push rod 803, rectangular block 804, and first cone block 805 to rotate, adjusting the usage state of the first cone block 805 relative to multiple second cone blocks 806. Then, the electric push rod 803 drives the rectangular block 804 and the first cone block 805 to move. During this movement, the first cone block 805 presses against the second cone blocks 806 in their respective positions, causing the second cone block 806 at this position to move the horizontal plate 807, connecting block 808, and slider 810, adjusting the extension state of the slider 810 relative to the circular base 6. Similarly, ... The extension state of the slider 810 around the relative position can be gradually adjusted, thereby adjusting the usage state of the outer contour of the round seat 6. At the same time, the round seat 802 will drive the annular seat 901 and the arc groove 906 opened inside to rotate. During the process of the electric push rod 803 completing the position adjustment of the relative slider 810, the roller 902 at the position of the relative slider 810 and the connecting block 808 will enter the arc groove 906. At this time, the third spring 904 will drive the roller 902, the fixing rod 903 and the fixing block 905 to move, releasing the limiting and fixing state of the fixing block 905 on the connecting block 808.

[0053] After the relative position of the slider 810 is adjusted, the second motor 801 will drive the circular seat 802 and the annular seat 901 to rotate. At this time, the contact state between the first cone block 805 and the second cone block 806 is not completely disengaged. The roller 902 will first disengage from the arc groove 906, and under the action of the annular seat 901, the roller 902 will drive the fixing rod 903 and the fixing block 905 to fix the connecting block 808, thereby fixing the extended state of the slider 810. When it is necessary to fix the usage position of multiple sliders 810, it is only necessary to drive the second motor 801 to rotate the circular seat 802 and the annular seat 901, and rotate the arc groove 906 between the two rollers 902. It is convenient to use.
