Therefore, general detection equipment cannot accurately simulate these vibrations and shaking during detection, resulting in the inability to accurately assess the potential leakage risk of the reducer caused by vibration in the actual working environment. As a result, during use, it is impossible to effectively prevent and reduce the occurrence of such leakage, thereby affecting the performance and life of the reducer. Summary of the invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an industrial robot reducer leakage detection device, comprising two bottom plates, the tops of the two bottom plates are fixedly connected to mounting frames, one of the mounting frames is installed with a fixed block on one side of the top, and the top of the other mounting frame is slidably connected to two limit frames, a test mechanism is installed between the two mounting frames, a positioning mechanism is installed on the top of the test mechanism, and the positioning mechanism is used to position the industrial robot reducer to be tested; The testing mechanism comprises a rotating plate and a hollow frame, the rotating plate is located at the center of the inner side of the hollow frame, a cam is fixedly connected to the center of one side of the rotating plate, one end of the cam is rotatably connected to a first linkage rod, one end of the first linkage rod is rotatably connected to a second linkage rod, the middle of the second linkage rod is fixedly connected to a center rod, one end of the center rod is rotatably connected to a push rod, a guide block is fixedly connected to the center of the top of the hollow frame, the guide block is slidably connected to the fixed block, a lifting block is fixedly connected to the top of the guide block, a second sliding groove is opened in the center of the top of the lifting block, a second slider is slidably connected inside the second sliding groove, a test bench is fixedly connected to the top of the second slider, and a connecting frame is fixedly connected to the center of one side of the test bench.

[0007] Preferably, a driving motor is installed on one side of the fixed block, and an output end of the driving motor is fixedly connected to the rotating plate.

[0008] Preferably, one end of the central rod is rotatably connected to one of the side walls of the mounting frame, and the diameter of the rotating plate is the same as the inner width of the hollow frame.

[0009] Preferably, the cross section of the second sliding block is a trapezoidal structure, and the bottom end width of the second sliding block is greater than the second sliding groove.

[0010] Preferably, the positioning mechanism includes a mounting block, the mounting block is located on the inner side of the test bench, and the bottom of the mounting block is fixedly connected to the center of the top of the test bench, a first slide groove is opened on the inner side of the mounting block, and a support frame is fixedly connected to the center of the inner cavity of the first slide groove.

[0011] Preferably, a bidirectional screw rod is rotatably connected in the center of the support frame, and two first sliding blocks are slidably connected to the inner side of the first sliding groove, and the two first sliding blocks are symmetrically distributed inside the first sliding groove.

[0012] Preferably, the cross section of the first sliding block is a trapezoidal structure, and the bottom width of the first sliding block is greater than the top width of the first sliding groove.

[0013] Preferably, the first sliding block is connected to the outer surface of the bidirectional screw rod via threads, and a knob is fixedly connected to one end of the bidirectional screw rod.

[0014] Preferably, two clamping plates are symmetrically installed above the mounting block, and the bottoms of the two clamping plates are fixedly connected to the tops of the two first sliding blocks respectively.

[0015] A method for detecting leakage of an industrial robot reducer comprises the following steps: Step 1: Pre-test preparation: place the industrial robot reducer to be tested between two clamping plates, and place a solution test paper on the inside of the test bench; Step 2: Lock and turn the knob so that the knob drives the bidirectional screw to move. The bidirectional screw uses the threads on the surface to control the two first sliders to move downward, and then the clamping plate is moved to position the reducer of the industrial robot to be tested; Step 3: Start the test. When the driving motor is running, the rotating plate and the cam are driven to rotate. Under the coordinated action of the first linkage rod, the second linkage rod and the push rod, the lifting block can move up and down, and the test bench can move back and forth in a straight line, so that the industrial robot reducer to be tested keeps shaking. Step 4: Record the results. When the test time reaches 10-60 minutes, stop the test bench immediately after the test and carefully observe the test paper results. The color change or wetness on the test paper will directly reflect the leakage of the reducer during the test. Then repeat the test several times and record the test results.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the rotating plate rotates around a non-center point, the dynamic force it generates acts on the hollow frame, causing it to produce a vertical reciprocating motion up and down. The cam rotates with the rotating plate, and drives the push rod through the interaction of the first linkage rod and the second linkage rod. Due to the constraint of the center rod, the push rod can change its angle and rotation, ensuring that the lifting block performs a stable linear reciprocating motion in the second slide groove. The up and down motion of the hollow frame is transmitted to the lifting block through the guide block, and combined with the linear reciprocating motion to form a composite motion. This motion is transmitted to the industrial robot reducer on the inner side of the splint, generating strong shaking. This shaking simulates the vibration and impact that may occur in the actual working environment, so that the sealing performance and durability of the reducer can be more accurately evaluated, ensuring the comprehensiveness and accuracy of the reducer test.

[0017] 2. In the present invention, the rotating plate starts to rotate by driving the motor, and the cam matched with it rotates synchronously. The specific shape and trajectory of the rotating plate drive the hollow frame to perform precise up and down reciprocating motion. In this process, the guide block is closely linked with the hollow frame and moves synchronously with the up and down motion of the hollow frame. The fixed block provides a stable motion environment for the guide block and limits its motion range, ensuring the safety of the system. Under the guidance of the guide block, the lifting block also performs stable up and down reciprocating motion. This motion mode ensures the accuracy and reliability of the industrial robot reducer detection.

[0018] 3. In the present invention, the industrial robot reducer is precisely placed between two clamping plates with matching contours to ensure lossless clamping. By rotating the knob, it links the two-way screw to rotate. The threads at both ends of the screw are opposite, driving the two first sliders to move synchronously in the opposite directions or toward each other, thereby adjusting the spacing between the clamping plates. Under the constraint of the first slide groove, the first slider maintains stable linear movement to prevent deviation. As the knob rotates, the two clamping plates gradually move closer and finally tightly clamp the reducer. This clamping method is both stable and reliable, ensuring that the reducer will not fall off during the detection process. The entire adjustment process is simple and easy, and can quickly adapt to reducers of different sizes, providing a solid foundation for subsequent precise detection.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-6 As shown: an industrial robot reducer leakage detection device comprises two bottom plates 1, the tops of the two bottom plates 1 are fixedly connected with mounting frames 13, one of the mounting frames 13 is installed with a fixing block 12 on one side of the top, the top of the other mounting frame 13 is slidably connected with two limit frames 11, a test mechanism 3 is installed between the two mounting frames 13, a positioning mechanism 2 is installed on the top of the test mechanism 3, and the positioning mechanism 2 is used to position the industrial robot reducer to be tested; The testing mechanism 3 includes a rotating plate 32 and a hollow frame 31. The rotating plate 32 is located at the center of the inner side of the hollow frame 31. A cam 33 is fixedly connected to the center of one side of the rotating plate 32. One end of the cam 33 is rotatably connected to a first linkage rod 34. One end of the first linkage rod 34 is rotatably connected to a second linkage rod 35. A center rod 351 is fixedly connected to the middle of the second linkage rod 35. One end of the center rod 351 is rotatably connected to a push rod 36. A guide block 38 is fixedly connected to the center of the top of the hollow frame 31. The guide block 38 is slidably connected to the fixed block 12. A lifting block 37 is fixedly connected to the top of the guide block 38. A second slide groove 371 is provided in the center of the top of the lifting block 37. A second slider 391 is slidably connected inside the second slide groove 371. A test bench 39 is fixedly connected to the top of the second slider 391. A connecting frame 361 is fixedly connected to the center of one side of the test bench 39.

[0023] In this embodiment, first, when the rotating plate 32 performs a circular motion around a non-center point, the dynamic force generated by it has a complex and variable effect on the hollow frame 31. This asymmetric rotation not only causes the hollow frame 31 to be subjected to an upward force, but also the direction of this force changes as the rotating plate 32 continues to rotate. This change will cause the hollow frame 31 to generate an up and down reciprocating motion in the vertical direction.

[0024] When the cam 33 rotates with the rotating plate 32, it interacts with the second linkage rod 35 through the first linkage rod 34. Since the center of the second linkage rod 35 is fixed on the central rod 351, and the central rod 351 is rotatably connected to the mounting frame 13, the second linkage rod 35 can only swing around the central rod 351. This swing is converted into a driving force for the lifting block 37 through the push rod 36. Due to the constraint of the central rod 351, the push rod 36 can change the angle and rotate in the process of transmitting power, thereby ensuring that the lifting block 37 can perform stable linear reciprocating motion inside the second slide groove 371.

[0025] The up and down motion of the hollow frame 31 is transmitted to the lifting block 37 through the guide block 38, thereby combining with the linear reciprocating motion generated by the second linkage rod 35 through the push rod 36. This combined motion enables the lifting block 37 to perform not only up and down reciprocating motion, but also linear reciprocating motion. This composite motion is transmitted to the industrial robot reducer to be tested on the inner side of the clamping plate 26, causing it to shake strongly. By simulating various vibrations and shocks that may occur in the actual working environment, the sealing performance and durability of the reducer can be more accurately evaluated.

[0026] Embodiment 2: Figure 3-5 As shown, a driving motor 4 is installed on one side of the fixed block 12, and the output end of the driving motor 4 is fixedly connected to the rotating plate 32. One end of the central rod 351 is rotatably connected to the side wall of one of the mounting frames 13, and the diameter of the rotating plate 32 is the same as the inner width of the hollow frame 31. The cross section of the second slider 391 is a trapezoidal structure, and the bottom width of the second slider 391 is greater than the second slide groove 371.

[0027] In this embodiment, when the rotating plate 32 is started and driven to rotate by the driving motor 4, the cam 33 that closely matches the rotating plate 32 will also rotate synchronously with the rotating plate 32. Due to the specific shape and rotation trajectory of the rotating plate 32, it will interact with the hollow frame 31, thereby driving the hollow frame 31 to reciprocate up and down. This movement mode ensures that the hollow frame 31 can move up and down accurately and stably within a limited range.

[0028] At the same time, the guide block 38 is closely connected to the hollow frame 31. Therefore, when the hollow frame 31 reciprocates up and down, the guide block 38 will move with it. When the guide block 38 moves inside the fixed block 12, it will interact with the lifting block 37. This interaction enables the lifting block 37 to reciprocate up and down together with the guide block 38.

[0029] The fixing block 12 can not only provide a stable movement environment for the guide block 38, but also limit the movement range of the guide block 38, thereby avoiding the situation of separation, which not only improves the safety of the entire system, but also ensures the accuracy and reliability of the detection.

[0030] During the lifting process of the guide block 38, its stable motion trajectory also ensures that the lifting block 37 can maintain stable motion. This stability is crucial for the detection of multiple industrial robot reducers. It can ensure that each reducer can be accurately and consistently detected, thereby improving the efficiency and accuracy of the detection.

[0031] Embodiment 3: According to Figure 6-7As shown, the positioning mechanism 2 includes a mounting block 21, which is located on the inner side of the test bench 39, and the bottom of the mounting block 21 is fixedly connected to the center of the top of the test bench 39. A first slide groove 22 is provided on the inner side of the mounting block 21, and a support frame 24 is fixedly connected to the center of the inner cavity of the first slide groove 22. A bidirectional screw rod 27 is rotatably connected to the center of the support frame 24, and two first sliders 23 are slidably connected to the inner side of the first slide groove 22, and the two first sliders 23 are symmetrically distributed inside the first slide groove 22. The cross section of the first slider 23 is a trapezoidal structure, and the width of the bottom end of the first slider 23 is greater than the width of the top of the first slide groove 22. The first slider 23 is connected to the outer surface of the bidirectional screw rod 27 by threads, and a knob 25 is fixedly connected to one end of the bidirectional screw rod 27. Two clamps 26 are symmetrically installed above the mounting block 21, and the bottoms of the two clamps 26 are fixedly connected to the tops of the two first sliders 23 respectively.

[0032] In this embodiment, first, the industrial robot reducer is accurately placed on two clamping plates 26. The two clamping plates 26 have contours that match the reducer surface to ensure that no damage is caused during the clamping process.

[0033] When the spacing of the clamping plates 26 needs to be adjusted to accommodate reducers of different sizes, the staff can operate by rotating the knob 25. The knob 25 is connected to the bidirectional screw rod 27. When the knob 25 is rotated, it drives the bidirectional screw rod 27 to rotate together. The surfaces of both ends of the bidirectional screw rod 27 are engraved with opposite threads, so that the screw rod can simultaneously control the sliding of the two first sliders 23 when rotating.

[0034] As the bidirectional screw rod 27 rotates, the two first sliders 23 will move in opposite or opposite directions according to the direction of the thread. This ensures that no matter how big the reducer is, the clamping plate 26 can be accurately adjusted to a suitable spacing. At the same time, the first slider 23 will be restricted by the first slide groove 22 when moving, and this restriction ensures that the slider can maintain stable linear motion and avoid deviation or shaking during the movement.

[0035] When the two clamping plates 26 are brought close together by the movement of the first slider 23, they will tightly clamp the industrial robot reducer in the middle. This clamping method is not only stable and reliable, but also can effectively prevent the reducer from falling off during the detection process.

[0036] Embodiment 4: A method for detecting leakage of an industrial robot reducer, comprising the following steps: 1) Preparing for testing: placing the industrial robot reducer to be tested between two clamping plates 26, and placing a solution test paper inside the test table 39; 2) Lock and turn the knob 25, so that the knob 25 drives the bidirectional screw 27 to move. The bidirectional screw 27 uses the threads on the surface to control the two first sliders 23 to move downward, and then the clamping plate 26 is moved to position the reducer of the industrial robot to be tested; 3) When the test starts, the driving motor 4 is used to drive the rotating plate 32 and the cam 33 to rotate. Under the coordinated action of the first linkage rod 34, the second linkage rod 35 and the push rod 36, the lifting block 37 can move up and down, and the test table 39 can move back and forth in a straight line, so that the industrial robot reducer to be tested shakes continuously; 4) Record the results. When the test time reaches 10-60 minutes, stop the operation of the test bench 39 immediately after the test is completed, and carefully observe the results of the test paper. The color change or wetness on the test paper will directly reflect the leakage of the reducer during the test. Then repeat the test several times and record the test results.

[0037] The method of use and working principle of the device: First, the reducer is carefully placed between the two clamping plates 26. By rotating the knob 25, the bidirectional screw 27 can be easily driven to rotate. This rotation action utilizes the opposite threads on the two ends of the screw to effectively control the sliding direction of the two first sliders 23 on the screw. Due to the design of the thread direction, the two sliders will move in opposite or opposite directions, ensuring the accuracy and stability of clamping.

[0038] During the movement of the sliders, they are strictly restricted by the first slide groove 22, ensuring the accuracy and stability of the linear motion, thereby avoiding the risk of the sliders detaching from the mounting block 21. The movement of the two sliders further drives the synchronous movement of the two clamping plates 26, so that the industrial robot reducer to be tested can be accurately positioned and firmly clamped. This design not only ensures the stability of the reducer during the test process, but also effectively prevents it from falling off during the test process.

[0039] Next, by starting the driving motor 4, the rotating plate 32 starts to rotate. This rotation not only drives the synchronous rotation of the cam 33, but also triggers the up and down reciprocating motion of the hollow frame 31. The guide block 38 moves with the movement of the hollow frame 31, thereby driving the lifting block 37 to reciprocate up and down inside the fixed block 12. The design of the fixed block 12 ensures the stability and safety of the guide block 38 during the movement, avoiding the risk of it falling off the track.

[0040] During the circular motion of the rotating plate 32, since its rotation center is not located at the center of the circle, a force is exerted on the hollow frame 31, causing it to move upward. As the rotating plate 32 continues to rotate, when the upward force is no longer exerted on the hollow frame 31, the hollow frame 31 will fall due to gravity. This continuous rotational motion causes the hollow frame 31 to produce a stable up and down reciprocating motion.

[0041] At the same time, when the rotating plate 32 rotates, the cam 33 also rotates synchronously. The rotation of the cam 33 drives the movement of the first linkage rod 34, and then drives the movement of the push rod 36 through the second linkage rod 35. Since the center of the second linkage rod 35 is located on the central rod 351, and the central rod 351 is rotatably connected to the mounting frame 13, the second linkage rod 35 remains stable in the horizontal position and only swings around the central rod 351. This swing transmits power to the lifting block 37 through the push rod 36, causing it to perform linear reciprocating motion inside the second slide groove 371. Due to the existence of the central rod 351, the push rod 36 can flexibly change the angle and rotation direction during the power transmission process, ensuring the smooth transmission of power.

[0042] Finally, the up and down reciprocating motion of the lifting block 37 is combined with the linear reciprocating motion to act on the industrial robot reducer to be tested through the clamping plate 26, causing it to shake strongly. This shaking helps to detect whether the reducer has quality problems such as leakage, thereby improving the accuracy and reliability of the detection.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
