Description

Technical Field

[0001] This invention relates to the field of speed reducer running-in test equipment, and more specifically to a speed reducer running-in test workbench. Background Technology

[0002] For debugging a speed reducer with a self-matched motor, the direct insertion method of the motor is generally used to ensure that the speed reducer has no abnormal noise, the gears have no single-point abnormal noise, and there is no abnormal temperature rise.

[0003] The speed reducer running-in test is a critical process before leaving the factory and is one of the quality control points. In the current batch commissioning process, the traditional direct-insertion motor has prominent problems: the motor used for commissioning needs to be configured with multiple frame sizes according to the size of the connection flange, resulting in a large variety of motors, frequent disassembly and assembly, repetitive actions, low commissioning efficiency, long speed reducer operation and testing time, and low interoperability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art.

[0005] This machine provides a high-efficiency speed reducer running-in test bench that reduces the need for frequent motor disassembly and assembly during commissioning, thereby reducing labor costs and improving commissioning efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a speed reducer running-in test workbench, comprising a workbench body, characterized in that: a motor pad and a speed reducer base bracket are installed on the workbench body, the motor pad is used to place the motor, and the speed reducer base bracket is used to place the speed reducer with a connecting flange; after the motor is placed on the motor pad and the speed reducer is placed on the speed reducer base bracket, the motor shaft and the speed reducer shaft are aligned and opposite each other; a first height adjustment device is provided between the motor pad and the workbench body, and a second height adjustment device is provided between the speed reducer base bracket and the workbench body; a drive device is provided on one side of the workbench body to drive the motor pad and the speed reducer base bracket to move horizontally while adjusting the height of the motor pad and the speed reducer base bracket through the first and second height adjustment devices.

[0007] Using the above technical solution, the traditional direct-plug motor debugging method has prominent problems: the motor used for debugging needs to be configured with multiple frame sizes according to the size of the connection flange, resulting in a large number of motor types, frequent disassembly and assembly, repetitive actions, and low debugging efficiency. The previous method resulted in long test times and low interoperability for speed reducers. This invention addresses this by employing a drive device with two horizontally driven motor pads and speed reducer base brackets. The heights of the motor pads and speed reducer base brackets are adjusted using first and second height adjustment devices to ensure the motor on the motor pad and the speed reducer on the speed reducer base bracket are at the same center height. Connecting shafts compatible with the motor's output shaft and the speed reducer shaft are used to connect them. A positioning flange and flange positioning plate then quickly position the speed reducer, allowing for a speed reducer run-in test. For batch testing, only the speed reducer needs to be repeatedly replaced. After changing the speed reducer model, simply adjusting the heights of the motor pads and speed reducer base brackets using the first and second height adjustment devices ensures the motor and speed reducer are at the same center height. This eliminates the need for multiple motor models, enhances versatility, reduces the workload of test operators, significantly lowers run-in test costs, and improves run-in test efficiency.

[0008] The aforementioned speed reducer running-in test workbench can be further configured as follows: the first and second height adjustment devices each include a first slider mounted on the workbench body, the side of the first slider away from the workbench body is a first guide slope, a second slider that can slide relative to the first guide slope is provided on the first guide slope, the side of the second slider facing the first guide slope is a second guide slope that fits against the first guide slope, the other side of the second slider opposite to the second guide slope is a horizontal mounting surface, and the driving device is connected to the first slider in a transmission manner.

[0009] By adopting the above technical solution, a first guide slope is set on the first slider, and a second guide slope that fits with the first guide slope is set on the second slider. The motor pad and the base pad are installed on a horizontal mounting surface. The motor on the motor pad and the reducer on the reducer base bracket are both placed on the horizontal mounting surface and are in a horizontal state. The first slider is driven by the driving device to slide relative to the guide slope of the second slider, thereby adjusting the height of the motor pad and the reducer base pad so that the center height of the motor and the reducer on both are consistent, which is convenient for adjustment.

[0010] The aforementioned speed reducer running-in test bench can be further configured as follows: the driving device includes a driving handwheel, the first slider is provided with a baffle for mounting the driving handwheel near the driving handwheel, the driving handwheel is provided with a lead screw that passes through the baffle and is threadedly connected to the first slider, and a limit structure is provided between the other end of the first slider opposite to the baffle and the second slider.

[0011] By adopting the above technical solution, the first slider, which is fixedly connected to the lead screw and driven by the handwheel, moves back and forth with the lead screw to adjust the center height between the motor pad and the reducer base pad. By setting a limit structure, the first slider and the second slider are prevented from disintegrating due to excessive stroke caused by the handwheel drive, thus improving stability.

[0012] The aforementioned speed reducer running-in test bench can be further configured such that: the limiting structure includes a limiting notch provided in the middle of the end of the first slider away from the baffle, and a limiting baffle is installed on the second slider at the corresponding position of the limiting notch.

[0013] By adopting the above technical solution, a limiting baffle and a limiting notch are set. The limiting principle is that when the handwheel drives the first slider to move away from the handwheel, the maximum adjustment stroke is reached when the limiting notch and the limiting baffle are in contact. This limits the maximum distance the first slider can move away from the second slider, thereby improving the stability of the device.

[0014] The aforementioned speed reducer running-in test bench can be further configured such that a sliding guide structure is provided between the first guide slope and the second guide slope.

[0015] By adopting the above technical solution, a sliding guide structure is set between the first guide slope and the second guide slope to improve the stability when the two slide relative to each other.

[0016] The aforementioned speed reducer running-in test bench can be further configured such that: the sliding guide structure includes a guide groove disposed opposite to the first slider, and the second slider is provided with a guide protrusion at a corresponding position of the guide groove that matches the shape of the guide groove.

[0017] By adopting the above technical solution, a guide protrusion is provided on the first slider and a guide groove is provided on the second slider, or vice versa, a guide groove is provided on the first slider and a guide protrusion is provided on the second slider, thereby guiding the sliding of both sliders.

[0018] The beneficial effects of this invention are: it enables batch debugging of self-matched motor reducers without disassembling and assembling the motor, thereby improving the efficiency of running-in tests, eliminating the need for multiple types of motors, and ensuring strong interoperability.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] See Figures 1-6 As shown: A speed reducer running-in test workbench includes a workbench body 1. A motor pad 2 and a speed reducer base bracket 3 are mounted on the workbench body 1 and are arranged opposite to each other. The motor pad 2 is used to place the motor, and the speed reducer base bracket 3 is used to place the speed reducer with a connecting flange. After the motor is placed on the motor pad 2 and the speed reducer is placed on the speed reducer base bracket 3, the motor shaft and the speed reducer shaft are in the same straight line and are arranged opposite to each other. A first height adjustment device is provided between the motor pad 2 and the workbench body 1, and a second height adjustment device is provided between the speed reducer base bracket 3 and the workbench body 1. A drive device 6 is provided on one side of the workbench body 1 to drive the motor pad 2 and the speed reducer base bracket 3 to move in the horizontal direction and adjust the height of the motor pad 2 and the speed reducer base bracket 3 through the first and second height adjustment devices.

[0027] Traditional direct-plug motor debugging has prominent problems: the motor used for debugging needs to be configured with multiple frame sizes according to the size of the connection flange, resulting in a wide variety of motors, frequent disassembly and assembly, repetitive actions, and low debugging efficiency. The previous method resulted in long test times and low interoperability for speed reducers. This invention addresses this by employing a drive device with two horizontally driven motor pads and speed reducer base brackets. The heights of the motor pads and speed reducer base brackets are adjusted using first and second height adjustment devices to ensure the motor on the motor pad and the speed reducer on the speed reducer base bracket are at the same center height. Connecting shafts compatible with the motor's output shaft and the speed reducer shaft are used to connect them. A positioning flange and flange positioning plate are then used to quickly position the speed reducer, allowing for a speed reducer run-in test. For batch testing, only the speed reducer needs to be repeatedly replaced. After changing the speed reducer model, simply adjusting the heights of the motor pads and speed reducer base brackets using the first and second height adjustment devices ensures the center heights of the motor and speed reducer are consistent. This eliminates the need for multiple motor models, enhances versatility, reduces the workload of test operators, significantly lowers the cost of run-in testing, and improves the efficiency of run-in testing.

[0028] The first and second height adjustment devices each include a first slider 4 installed on the workbench body 1. The side of the first slider 4 away from the workbench body 1 is a first guide slope 41. A second slider 5 that can slide relative to the first guide slope 41 is provided on the first guide slope 41. The side of the second slider 5 facing the first guide slope 41 is a second guide slope 51 that fits against the first guide slope 41. The other side of the second slider 5 that is opposite to the second guide slope 51 is a horizontal mounting surface 52. The driving device 6 is connected to the first slider 4 in a transmission manner.

[0029] By setting a first guide slope on the first slider and a second guide slope that fits with the first guide slope on the second slider, the motor pad and the base pad are installed on a horizontal mounting surface. The motor on the motor pad and the reducer on the reducer base bracket are both placed on the horizontal mounting surface in a horizontal state. The first slider is driven by the drive device to slide relative to the guide slope of the second slider, thereby adjusting the height of the motor pad and the reducer base pad so that the center height of the motor and the reducer on both are consistent, which is convenient for adjustment.

[0030] The drive device 6 includes a drive handwheel 61. A baffle 7 for mounting the drive handwheel 61 is provided near the drive handwheel 61. A lead screw 8 passes through the baffle 7 and is threadedly connected to the first slider 4. A limit structure is provided between the other end of the first slider 4 opposite to the baffle 7 and the second slider 5. The baffle 7 can be configured as a connecting flange.

[0031] The first slider, which is fixedly connected to the lead screw by a handwheel drive, moves back and forth with the lead screw to adjust the center height between the motor pad and the reducer base pad. By setting a limit structure, it is prevented that the first slider and the second slider will disintegrate due to excessive stroke of the handwheel drive, thus improving stability.

[0032] The limiting structure includes a limiting notch 81 provided at the middle of the end of the first slider 4 away from the baffle 7, and a limiting baffle 9 installed on the second slider 5 at the corresponding position of the limiting notch 81;

[0033] By setting the limiting baffle 9 and the limiting notch 81, the limiting principle is that when the handwheel drives the first slider to move away from the handwheel, the maximum adjustment stroke is reached when the limiting notch and the limiting baffle are in contact, thus limiting the maximum distance of the first slider away from the second slider and improving the stability of the device.

[0034] A sliding guide structure is provided between the first guide slope 41 and the second guide slope 51;

[0035] A sliding guide structure is provided between the first guide slope 41 and the second guide slope 51 to improve the stability when the two slide relative to each other;

[0036] The sliding guide structure includes a guide groove 42 disposed on the first guide slope 41 of the first slider 4, and a guide protrusion 53 adapted to the shape of the guide groove 42 is provided on the second guide slope 51 of the second slider 5 at the corresponding position of the guide groove 42.

[0037] By setting a guide protrusion on the first slider and a guide groove on the second slider, or vice versa, setting a guide groove on the first slider and a guide protrusion on the second slider, the sliding of both can be guided. Furthermore, limiting steps 43 can be set on both sides of the first guide slope 41, and a guide bar 54 that can slide in the limiting step 43 can be set on the second guide slope 51 facing the limiting step 43 to achieve further limiting.

[0038] Batch debugging of self-matched motor reducers can be completed without disassembling and assembling the motor, thereby improving the efficiency of running-in tests. It does not require the configuration of multiple types of motors and has strong interoperability.
