Description

Technical Field

[0001] This utility model relates to the field of coupling dynamic balancing testing technology, specifically to an auxiliary clamping fixture for coupling dynamic balancing testing. Background Technology

[0002] As a core component in a mechanical transmission system that connects two shafts (or a shaft and a rotating part), the uneven mass distribution of the coupling can cause centrifugal force during rotation, leading to equipment vibration, noise, and component wear, and even shortening its service life.

[0003] Dynamic balancing testing of couplings refers to the process of using a dynamic balancing machine to inspect a rotating coupling, quantify its imbalance (centrifugal force deviation caused by mass eccentricity), and determine the correction position. The purpose is to control the imbalance of the coupling during rotation within the allowable range through targeted correction (such as removing or adding counterweights), thereby ensuring the smooth operation of the transmission system and reducing the equipment failure rate.

[0004] The existing device has poor clamping effect, and the coupling is prone to slippage or axial movement when rotating at high speed, which introduces additional vibration interference and affects the test results. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary clamping fixture for dynamic balancing testing of couplings, so as to solve the problems mentioned in the background art, such as poor clamping effect of the device, easy slippage or axial movement of the coupling during high-speed rotation, introduction of additional vibration interference, and impact on the test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary clamping fixture for dynamic balancing testing of couplings, comprising a testing box, a mounting plate, a base, and a coupling, wherein the mounting plate is fixedly connected to the right side of the base, the testing box is installed above the base, the coupling is connected to the inside of the testing box, and a radial clamping device is provided inside the testing box;

[0007] The radial clamping device includes a clamping frame, a cylinder, a fixing block, and rollers. The fixing blocks are fixedly connected to the upper and lower left and right sides inside the testing box and are arranged in a circumferential manner. The clamping frame is connected to the output end of the cylinder. The cylinder is fixedly installed on one side of the fixing block. The rollers are rotatably connected to one side of the clamping frame. The outer surface of the clamping frame contacts the outer surface of the coupling. The cylinder drives the clamping frame to move, thereby making the rollers fit tightly against the outer surface of the coupling and radially clamp it.

[0008] Preferably, the roller has a rubber outer layer and anti-slip grooves on its outer surface, which can prevent the coupling from moving axially during testing and affecting the test results.

[0009] Preferably, the clamping frame is rotatably connected to a rotating block on the side near the roller, and a limiting block is slidably connected to the side of the clamping frame near the roller. The size of the through hole opened inside the rotating block matches the size of the limiting block. Rotating the rotating block can disassemble the limiting block, making it convenient to replace the roller.

[0010] Preferably, the left side of the testing box is threaded with an adjusting column, the left end of which is fixedly connected to a knob, and the right end of which is rotatably connected to a clamping block. The right side of the clamping block contacts the left side of the coupling. By rotating the knob, the adjusting column is rotated, thereby causing the clamping block to move and fit against the left end of the coupling to limit its movement.

[0011] Preferably, a bracket is fixedly connected to the upper right side of the mounting plate, a drive motor is fixedly mounted on the right side of the bracket, a drive wheel is connected to the output end of the drive motor, a driven wheel is rotatably connected to the right side of the mounting plate, a transmission belt is connected to the outer surfaces of the drive wheel and the driven wheel, a threaded post is threadedly connected to the inner surface of the driven wheel, an adjusting nut is rotatably connected to the right side of the driven wheel, the adjusting nut is threadedly connected to the outer surface of the threaded post, a bearing is fixedly mounted on the upper part of the mounting plate, the driven wheel is rotatably connected to the upper part of the mounting plate through the bearing, and an adjusting block is fixedly connected to the left end of the threaded post. A rubber plug is connected to the right side of the coupling. The right side of the rubber plug is fitted onto the outer surface of the adjusting block. A test end is installed on the upper left side of the mounting plate. The test end is connected to the test end of the dynamic balancing instrument. The rubber plug is tapered inside. By rotating the adjusting nut, the threaded column rotates, which moves the adjusting block and squeezes the inside of the rubber plug, causing it to expand outward and fit tightly against the right side of the coupling. The drive motor drives the driving wheel, driven wheel, and transmission belt to move, thereby driving the threaded column, adjusting block, and rubber plug to rotate. Finally, the coupling rotates to cooperate with the dynamic balancing instrument for dynamic balancing testing.

[0012] Preferably, a slide rail is provided on the top of the base, and a hydraulic cylinder is fixedly installed on the left side of the base. The output end of the hydraulic cylinder is connected to a mounting seat, and a slider is fixedly connected to the bottom of the mounting seat. The slider is slidably connected inside the slide rail. The hydraulic cylinder drives the mounting seat to move, which in turn drives the detection box to move so that the coupling and the rubber plug cooperate to axially clamp and limit the coupling.

[0013] Preferably, a fixing plate is fixedly connected to the upper part of the mounting base, a lifting motor is fixedly installed on one side of the fixing plate, a gear is connected to the output end of the lifting motor, a rack is slidably connected to the upper part of the mounting base, the rack meshes with the outer surface of the gear, and the rack is fixedly connected to the bottom of the detection box. The lifting motor drives the gear to rotate, thereby driving the rack and the detection box to rise and fall so that the coupling adapts to the height of the rubber plug.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This coupling dynamic balancing test auxiliary clamping fixture uses a cylinder to move the clamping frame, thereby tightly fitting the rollers to the outer surface of the coupling for radial clamping. The anti-slip groove prevents axial movement of the coupling during testing, which could affect the test results. Rotating the rotating block allows the limit block to be disassembled for easy replacement of the rollers. Rotating the knob rotates the adjusting column, which in turn moves the clamping block to fit against the left end of the coupling for limiting its position. The rubber plug has a conical interior. Rotating the adjusting nut rotates the threaded column, which in turn moves the adjusting block to compress the rubber plug, causing it to expand outward and fit tightly against the right side of the coupling. The drive motor drives the driving wheel, driven wheel, and transmission belt, which in turn rotates the threaded column, adjusting block, and rubber plug, ultimately causing the coupling to rotate to cooperate with the dynamic balancing tester for dynamic balancing testing.

[0016] 2. The coupling dynamic balancing test auxiliary clamping fixture uses a hydraulic cylinder to move the mounting base, which in turn moves the test box to make the coupling engage with the rubber plug for axial clamping and limiting. A lifting motor drives the gear to rotate, which in turn moves the rack and test box to adjust the coupling to the height of the rubber plug. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Addressing the current issues of poor clamping performance in existing devices, which easily lead to coupling slippage or axial movement during high-speed rotation, introducing additional vibration interference and affecting test results, this example provides an auxiliary clamping fixture for coupling dynamic balancing testing. Please refer to [link / reference]. Figures 1-8 This embodiment provides an auxiliary clamping fixture for dynamic balancing testing of couplings, which can radially clamp and axially limit the couplings, with good clamping effect. The auxiliary clamping fixture for dynamic balancing testing of couplings includes a testing box 1, a mounting plate 101, a base 102, and a coupling 103. The mounting plate 101 is fixedly connected to the right side of the base 102, the testing box 1 is mounted above the base 102, and the coupling 103 is connected inside the testing box 1. A radial clamping device is provided inside the testing box 1.

[0028] The radial clamping device includes a clamping frame 2, a cylinder 201, a fixing block 202, and a roller 203. The fixing block 202 is fixedly connected to the upper and lower left and right sides inside the detection box 1 and is arranged in a circle. The clamping frame 2 is connected to the output end of the cylinder 201. The cylinder 201 is fixedly installed on one side of the fixing block 202. The roller 203 is rotatably connected to one side of the clamping frame 2. The outer surface of the clamping frame 2 is in contact with the outer surface of the coupling 103. The roller 203 is made of rubber and has anti-slip grooves on its outer surface. A rotating block 204 is rotatably connected to the side of the clamping frame 2 near the roller 203. A limiting block 205 is slidably connected to the side of the clamping frame 2 near the roller 203. The size of the through hole opened inside the rotating block 204 and the limiting block 205 are matched.

[0029] The left side of the test box 1 is threaded with an adjusting column 501. The left end of the adjusting column 501 is fixedly connected with a knob 5. The right end of the adjusting column 501 is rotatably connected with a clamping block 502. The right side of the clamping block 502 is in contact with the left side of the coupling 103.

[0030] A bracket 301 is fixedly connected to the upper right side of the mounting plate 101. A drive motor 3 is fixedly installed on the right side of the bracket 301. The output end of the drive motor 3 is connected to a drive wheel 302. A driven wheel 303 is rotatably connected to the right side of the mounting plate 101. A transmission belt 304 is connected to the outer surfaces of the drive wheel 302 and the driven wheel 303. A threaded post 305 is threadedly connected to the inner surface of the driven wheel 303. An adjusting nut 306 is rotatably connected to the right side of the driven wheel 303. The adjusting nut 306 is threadedly connected to the outer surface of the threaded post 305. A bearing 307 is fixedly installed on the upper part of the mounting plate 101. The driven wheel 303 is rotatably connected to the upper part of the mounting plate 101 through the bearing 307. An adjusting block 308 is fixedly connected to the left end of the threaded post 305. A rubber plug 309 is connected to the right side of the inside of the coupling 103. The right side of the rubber plug 309 is fitted onto the outer surface of the adjusting block 308. A test end 310 is installed on the upper left side of the mounting plate 101. The test end 310 is connected to the test end of the dynamic balancing tester.

[0031] In this embodiment, the cylinder 201 drives the clamping frame 2 to move, thereby making the roller 203 tightly fit against the outer surface of the coupling 103 and clamp it radially. The anti-slip groove can prevent the coupling 103 from axially moving during testing and affecting the test results. Rotating the rotating block 204 can disassemble the limiting block 205, making it easy to replace the roller 203. Rotating the knob 5 drives the adjusting column 501 to rotate, thereby driving the clamping block 502 to move and fit against the left end of the coupling 103 to limit it. The rubber plug 309 is set in a conical shape. By rotating the adjusting nut 306, the threaded column 305 rotates, driving the adjusting block 308 to move and squeeze the inside of the rubber plug 309 to expand it outward and fit tightly against the right side of the inside of the coupling 103. The drive motor 3 drives the driving wheel 302, the driven wheel 303 and the transmission belt 304 to move, thereby driving the threaded column 305, the adjusting block 308 and the rubber plug 309 to rotate, and finally driving the coupling 103 to rotate to cooperate with the dynamic balance tester to perform dynamic balance testing.

[0032] Example 2: Based on Example 1, please refer to... Figures 1-8The system can adjust the position and height of couplings of different sizes to align them with the clamping device. A slide rail is provided on the top of the base 102. A hydraulic cylinder 4 is fixedly installed on the left side of the base 102. The output end of the hydraulic cylinder 4 is connected to a mounting base 401. A slider 402 is fixedly connected to the bottom of the mounting base 401. The slider 402 is slidably connected inside the slide rail. A fixing plate 601 is fixedly connected to the top inside the mounting base 401. A lifting motor 6 is fixedly installed on one side of the fixing plate 601. A gear 602 is connected to the output end of the lifting motor 6. A rack 603 is slidably connected above the mounting base 401. The rack 603 meshes with the outer surface of the gear 602. The top of the rack 603 is fixedly connected to the bottom of the detection box 1.

[0033] In this embodiment, the hydraulic cylinder 4 drives the mounting base 401 to move, which in turn drives the detection box 1 to move so that the coupling 103 and the rubber plug 309 cooperate to axially clamp and limit the coupling 103. The lifting motor 6 drives the gear 602 to rotate, thereby driving the rack 603 and the detection box 1 to rise and fall so that the coupling 103 adapts to the height of the rubber plug 309.

[0034] Working principle: The cylinder 201 drives the clamping frame 2 to move, thereby causing the roller 203 to fit tightly against the outer surface of the coupling 103 and radially clamp it. The anti-slip groove can prevent the coupling 103 from axially moving during testing, affecting the test results. Rotating the rotating block 204 allows the limit block 205 to be disassembled, facilitating the replacement of the roller 203. Rotating the knob 5 drives the adjusting column 501 to rotate, thereby moving the clamping block 502 to fit against the left end of the coupling 103 and limit its movement. (Rubber plug...) The internal structure of the rubber plug 309 is tapered. Rotating the adjusting nut 306 causes the threaded column 305 to rotate, which in turn moves the adjusting block 308 to compress the rubber plug 309, causing it to expand outward and fit tightly against the right side of the coupling 103. The drive motor 3 drives the driving wheel 302, driven wheel 303, and transmission belt 304 to move, thereby causing the threaded column 305, adjusting block 308, and rubber plug 309 to rotate, ultimately causing the coupling 103 to rotate and cooperate with the dynamic balancing tester for dynamic balancing testing. The hydraulic cylinder 4 drives the mounting base 401 to move, which in turn moves the test box 1, allowing the coupling 103 to engage with the rubber plug 309 and axially clamp and limit the coupling 103. The lifting motor 6 drives the gear 602 to rotate, thereby causing the rack 603 and the test box 1 to rise and fall, allowing the coupling 103 to adapt to the height of the rubber plug 309. Hydraulic cylinder 4 is model CDH1H1-063 / 036 / 500, cylinder 201 is model SMCCQ2B32-50, drive motor 3 is model PRHD2-030, and lifting motor 6 is model 1FK7063.
