Description

Technical Field

[0001] This utility model relates to the field of bearing production and testing technology, and more specifically, to a bearing production and testing device. Background Technology

[0002] Currently, bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Bearing rings are annular parts of radial rolling bearings with one or more raceways. The contour of the bearing ring assembly needs to be inspected after machining.

[0003] Existing methods for measuring bearing roundness typically involve manually measuring the bearing's outer diameter using calipers. To facilitate multiple measurements and ensure accuracy, this not only results in poor inspection quality but also reduces inspection efficiency.

[0004] To address the above issues, application number 202421326971.0, entitled "A Testing Device for Bearing Production," describes a device comprising an operating table. A servo motor is fixedly mounted on one side of the operating table, and a limit mechanism is installed inside the operating table for fixing bearings of different models. A mounting plate is fixedly connected to one side of the operating table, and a testing mechanism is slidably connected inside the mounting plate for testing the outer diameter of bearings of different heights. The servo motor drives a connected bidirectional screw to rotate, causing a movable block to move a fixed plate and a limit plate to slide to both sides to fix the bearing. The telescopic rod and spring ensure that the limit plate fits against the inner wall of the bearing to be tested. Rotating a knob causes a slider to slide within a third groove to adjust the height of the dial indicator relative to the bearing. Subsequently, a second cylinder is controlled to bring the dial indicator into contact with the outer diameter of the bearing. This design can test bearings of different models while effectively reducing testing errors and improving work efficiency.

[0005] Although the device has many beneficial effects, it still has the following problems: In the actual testing process, the operator needs to manually rotate the bearing and use a dial indicator to test the outer diameter of the bearing point by point. Not only does it require frequent adjustment of the bearing position to ensure the comprehensiveness of the measurement, but this method of relying entirely on manual operation not only greatly increases the labor intensity of the staff, but also leads to low efficiency due to the cumbersome testing process. Especially in batch testing, human error is prone to occur and the time consumption is long.

[0006] In addition, after the bearing is machined, metal shavings and other impurities often adhere to its surface. If these impurities are not thoroughly cleaned before testing, they will accelerate the wear of the dial indicator's testing end, shortening the lifespan of the precision instrument. Furthermore, they will produce false readings during measurement, causing the outer diameter measurement results to deviate from the actual value, seriously affecting the accuracy of the test. In some cases, unqualified bearings may even flow into the next process, posing quality risks to subsequent assembly.

[0007] In view of this, we propose a bearing production testing device. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this invention is to provide a bearing production testing device to solve the problems mentioned in the background art.

[0010] 2. Technical Solution

[0011] A bearing production testing device includes a fixed base, a servo motor mounted on the side wall of the fixed base, a bidirectional lead screw connected to the output end of the servo motor, a clamping assembly for positioning the bearing sleeved on the outer circumference of the bidirectional lead screw, a dust collection assembly for collecting impurities on the outer wall of the bearing mounted on the right end of the fixed base, and a height-adjustable testing assembly mounted on the rear outer wall of the fixed base.

[0012] Preferably, the clamping assembly includes a first movable block and a second movable block sleeved on the outer circumferential wall of the bidirectional lead screw, and a first clamp and a second clamp are mounted on the top of the first movable block and the second movable block.

[0013] Preferably, the outer wall of the second clamp is welded with a connecting plate and a fixing plate, the inner wall of the second clamp is rotatably connected with a rotating roller and a driving roller, and a dust suction pipe is also connected to one side of the outer wall of the second clamp.

[0014] Preferably, a drive motor is provided at the bottom of the fixed plate, and a transmission belt is sleeved on the output end of the drive motor and the top of the drive roller. A rotating roller of the same size is rotatably connected to the inner wall of the clamp.

[0015] Preferably, the dust collection assembly includes a collection box installed on the outer wall of the right end of the fixed base. A threaded connecting cover is threaded onto the top of the collection box. A vacuum cleaner is provided on the top of the threaded connecting cover, and a filter cylinder is provided at the bottom of the threaded connecting cover. The suction end of the vacuum cleaner extends into the interior of the filter cylinder, and the end of the suction pipe is connected to the front outer wall of the collection box and communicates with its interior.

[0016] Preferably, the detection assembly includes a mounting bracket installed on the outer wall behind the fixed base. A threaded rod is rotatably connected to the top of the mounting bracket. A slider is sleeved on the outer circumference of the threaded rod. A cylinder is installed inside the slider. A fixed block is connected to the output end of the cylinder. A dial indicator is installed on the outer wall of the fixed block.

[0017] 3. Beneficial effects

[0018] Compared with the existing technology, the advantages of this utility model are as follows: In actual testing, the bearing can be placed between clamp one and clamp two. The bidirectional lead screw is driven to rotate by a servo motor to achieve clamping and limiting of bearings of different sizes. After clamping, the cylinder drives the dial indicator to move and fit against the outer wall of the bearing circumference. At the same time, the drive motor drives the drive roller to rotate through the transmission belt, so that the bearing rotates automatically at a uniform speed, completely replacing the traditional manual rotation testing method, greatly reducing the labor intensity of operators and significantly improving testing efficiency.

[0019] During the testing process, the bearing can be controlled to rotate once without load. Then, the cylinder is activated to move the dial indicator to the outer circumference of the bearing. While the bearing is rotating without load, a vacuum cleaner can be activated. The negative pressure generated by the vacuum cleaner is used to perform real-time suction cleaning of the outer circumference inside the fixture as the bearing rotates. This negative pressure suction design can effectively remove metal debris and other impurities attached to the bearing surface. This not only avoids wear on the dial indicator's testing end due to impurities, ensuring the service life of the precision instrument, but also eliminates interference from impurities on the test results, ensuring the accuracy of the outer diameter measurement data. This solves the problem of impurities affecting the testing accuracy and equipment wear. Attached Figure Description

[0027] Please see Figure 1-3 This utility model provides a technical solution:

[0028] A bearing production testing device includes a fixed base 100, a servo motor 110 disposed on the side wall of the fixed base 100, a bidirectional lead screw 111 connected to the output end of the servo motor 110, a clamping assembly for positioning the bearing sleeved on the outer circumference of the bidirectional lead screw 111, a dust collection assembly for collecting impurities on the outer wall of the bearing installed on the right end outer wall of the fixed base 100, and a height-adjustable testing assembly disposed on the rear outer wall of the fixed base 100.

[0029] Specifically, the clamping assembly includes a first movable block 120 and a second movable block 130 sleeved on the outer circumference of the bidirectional lead screw 111, and a first clamp 121 and a second clamp 131 are mounted on the top of the first movable block 120 and the second movable block 130.

[0030] In some embodiments, clamp one 121 and clamp two 131 can be fixed to the top of movable block one 120 and movable block two 130 respectively by bolts, so as to facilitate disassembly and replacement.

[0031] Furthermore, a connecting plate 134 and a fixing plate 135 are welded to the outer wall of the second fixture 131, and a rotating roller 132 and a driving roller 133 are rotatably connected to the inner wall of the second fixture 131. A dust suction pipe 138 is also connected to one side of the outer wall of the second fixture 131. The dust suction pipe 138 is a corrugated hose, which is convenient for suction and cleaning of impurities.

[0032] Furthermore, a drive motor 136 is provided at the bottom of the fixed plate 135. The output end of the drive motor 136 and the top of the drive roller 133 are connected together by a transmission belt 137. A rotating roller 132 of the same size is rotatably connected to the inner wall of the clamp 121.

[0033] Furthermore, the dust collection assembly includes a collection box 200 installed on the outer wall of the right end of the fixed base 100. A threaded connecting cover 210 is threaded onto the top of the collection box 200. A vacuum cleaner 220 is installed on the top of the threaded connecting cover 210, and a filter cartridge 230 is installed at the bottom of the threaded connecting cover 210. The suction end of the vacuum cleaner 220 extends into the filter cartridge 230. The end of the suction pipe 138 is connected to the front outer wall of the collection box 200 and communicates with its interior, facilitating suction cleaning of the outer wall of the bearing circumference.

[0034] It is worth noting that the testing assembly includes a mounting bracket 300 installed on the outer wall of the rear of the fixed base 100. A threaded rod 310 is rotatably connected to the top of the mounting bracket 300. A slider 320 is sleeved on the outer circumference of the threaded rod 310. A cylinder 330 is installed inside the slider 320. A fixed block 340 is connected to the output end of the cylinder 330. A dial indicator 350 is installed on the outer wall of the fixed block 340, which facilitates the outer diameter testing of the outer circumference of the bearing by means of the dial indicator 350.

[0035] In some embodiments, the cylinder 330 achieves telescopic control through a combination of pneumatic drive and precise limiting or feedback system. Its structure typically includes a cylinder barrel, piston, piston rod, and adjustable limiting device (or displacement sensor + proportional valve). During operation, compressed air pushes the piston to drive the piston rod. The mechanical limiting type uses limiting blocks, bolts, etc. inside or outside the cylinder to block the piston stroke. The pneumatic feedback type uses a sensor to monitor the piston rod position in real time and cuts off the air source or switches the air path through the control system. The proportional valve adjustment type uses a proportional valve to precisely control the air pressure to adjust the piston movement distance, thereby achieving flexible adjustment of the telescopic length to meet the needs of detecting the outer circumference of bearings of various sizes under different working conditions. The air source for the cylinder can be provided by an external air compressor. All of the above belong to the prior art.

[0036] In some embodiments, the device is powered by an external power source and can be controlled by an external PLC controller; all of the above are existing technologies.

[0037] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0038] Working principle: During actual testing, the bearing can be placed between fixture 121 and fixture 131. A servo motor 110 drives a bidirectional lead screw 111 to rotate, achieving clamping and limiting of bearings of different sizes. After clamping, a cylinder 330 moves a dial indicator 350 to fit against the outer circumference of the bearing. Simultaneously, the drive motor 110 drives the drive roller 133 to rotate via a transmission belt 137, causing the bearing to rotate automatically and at a uniform speed. This completely replaces the traditional manual rotation testing method, significantly reducing the labor intensity of operators and greatly improving testing efficiency. During the testing process, the bearing can be controlled to idle for a period of time. After rotating the bearing, cylinder 330 is activated to move dial indicator 350 to fit against the outer circumference of the bearing. While the bearing is spinning, vacuum cleaner 220 can be activated, using the negative pressure generated inside fixture 131 to perform real-time suction cleaning of the outer circumference of the bearing as it rotates. This negative pressure suction design can effectively remove metal debris and other impurities attached to the bearing surface, preventing impurities from wearing down the dial indicator's measuring end, ensuring the service life of the precision instrument, and eliminating the interference of impurities on the test results, ensuring the accuracy of the outer diameter measurement data, thereby solving the problem of impurities affecting the test accuracy and equipment wear.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
