Description

Technical Field

[0001] The invention belongs to the technical field of precision gear performance detection, and in particular relates to a precision right-angle reducer torsional stiffness and backlash detection device. Background Art

[0002] Some traditional detection methods, such as simple manual measuring tools combined with manual estimation, are difficult to perform high-precision measurements of the torsional stiffness and backlash of precision right-angle reducers. For the measurement of torsional stiffness, it is difficult to accurately control the magnitude and direction of the force when manually applying torque, and the accuracy of the measuring tool itself is limited, resulting in large errors in the measurement results. In terms of backlash measurement, it is impossible to accurately obtain tiny backlash values ​​by relying on manual observation and rough marking to judge the gap and other conditions. In addition, in automated production line equipment, precision right-angle reducers ensure the stability and accuracy of power transmission between each link, which is crucial to maintaining efficient and stable operation of the entire production line.

[0003] Existing equipment is often only suitable for one type of reducer during the testing process. When there are multiple types of reducers that need to be tested on the company's production line, if only special testing equipment of the corresponding model can be used, then during the testing process, it is necessary to frequently replace equipment and adjust testing parameters, etc. This makes the testing process extremely cumbersome, increases the time consumption of the testing link, and thus affects the efficiency of the entire production process. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a precision right-angle reducer torsional stiffness and backlash detection device.

[0005] The technical solution adopted to solve the above technical problems is: a precision right-angle reducer torsional stiffness and backlash detection device, including a support block, a mounting plate fixedly connected between the tops of multiple support blocks, a first connecting plate fixedly connected to the front end of the top of the mounting plate, and a plurality of second connecting plates slidably connected to the rear end of the top of the mounting plate, wherein a test piece is fixedly connected to the top of one of the second connecting plates, and adjustment components are installed on the tops of two of the second connecting plates, a clamping component is installed between the bottoms of the two adjustment components, and a test component is installed on the top of the first connecting plate.

[0006] Furthermore, the adjusting assembly includes a connecting rod fixedly connected to the top of the second connecting plate, a mounting block is fixedly connected between the tops of each two connecting rods, a first motor is installed on the tops of the two mounting blocks, a screw rod is fixedly connected to the bottoms of the two first motors, an adjusting block is threadedly connected to the outer walls of the two screw rods, two guide rods are slidably connected between the two adjusting blocks and the corresponding mounting blocks, a first sliding groove is provided on the inner walls of the plurality of connecting rods, a reinforcement block is slidably connected between each two of the first sliding grooves, two limiting grooves are provided on the bottom of one side of the two adjusting blocks, a sliding rod is slidably connected to the inner walls of the plurality of limiting grooves, a resist plate is fixedly connected between one side of each two sliding rods, and a spring is slidably connected to the outer walls of the plurality of sliding rods.

[0007] Through the above technical solution, the two first motors are started first, so that the two first motors drive the corresponding screw rods to rotate, and then the two screw rods drive the corresponding adjustment blocks to move up and down along the outer wall of the guide rod, and then the adjustment blocks drive the corresponding sliding rods, springs and abutment plates to reach the specified position.

[0008] Furthermore, the two screw rods and the plurality of guide rods are parallel to each other, and each screw rod is in the same plane as the corresponding two guide rods.

[0009] Through the above technical solution, the lateral deviation of the adjustment block in the direction perpendicular to the plane can be effectively limited, and the adjustment block can be more evenly distributed between the screw rod and the guide rod, while also extending the service life of the screw rod and the guide rod.

[0010] Furthermore, the outer walls of the two reinforcement blocks are tightly fitted with the corresponding inner walls of the first sliding grooves, and one side of the two reinforcement blocks is fixedly connected to the corresponding adjustment blocks.

[0011] Through the above technical solution, the wear can be relatively evenly distributed on the outer wall of the reinforcement block and the inner wall of the first slide groove. At the same time, it also helps to extend the service life of the reinforcement block and the first slide groove and reduce the maintenance cost of the device.

[0012] Furthermore, the clamping assembly includes a second slide groove opened at the rear end of the top of the mounting plate, a second motor is installed at the rear end of one side of the mounting plate, a bidirectional threaded rod is fixedly connected to the output end of the second motor, two linkage blocks are threadedly connected to the outer wall of the bidirectional threaded rod, and a bearing is fixedly connected to the side of the second slide groove away from the second motor.

[0013] Through the above technical solution, the second motor is first started so that the second motor drives the bidirectional threaded rod to rotate, and then the bidirectional threaded rod drives the two linkage blocks to move in opposite directions. At the same time, the two linkage blocks drive the corresponding second connecting plates to move synchronously, and then the two second connecting plates drive the corresponding adjustment components to move synchronously, thereby achieving the purpose of reinforcing the test piece.

[0014] Furthermore, the tops of the two linkage blocks are fixedly connected to the corresponding bottoms of the second connecting plates, and the inner wall of the bearing is connected to one side of the outer wall of the bidirectional threaded rod.

[0015] Through the above technical solution, the force transmitted through the bearing can be transmitted to the linkage block via the bidirectional threaded rod, and then transmitted to the second connecting plate by the linkage block. At the same time, loosening and detachment between the linkage block and the second connecting plate are prevented, thereby ensuring the structural stability of the entire device.

[0016] Furthermore, the test assembly includes two mounting plates fixedly connected to the top of the mounting plate, hydraulic rods are installed on the top of the two mounting plates, force sensors are fixedly connected to the top of the two hydraulic rods, a frame is fixedly connected to the top of the mounting plate, an angle encoder is fixedly connected to the front end of the frame, and a detection piece is slidably connected to the front end of the test piece.

[0017] Through the above technical solution, one of the hydraulic rods is first started, so that the hydraulic rod drives the corresponding force sensor to move upward. At the same time, the other force sensor and angle encoder will receive the data and upload it to the database for observation through the display.

[0018] Furthermore, both sides of the bottom of the detection member fit with the top of the corresponding force sensor.

[0019] Through the above technical solution, the stability of the connection between the detection piece and the force sensor is enhanced. At the same time, during the operation of the detection device, no matter whether it is subjected to external interference forces such as vibration and impact, this stable connection can effectively resist and prevent the detection piece and the force sensor from loosening or detaching, thereby ensuring the structural stability of the entire detection device.

[0020] The beneficial effects of the present invention are as follows: (1) By setting an adjustment component, the present invention makes the detection process more flexible, greatly shortens the time consumed by operations such as changing equipment and re-debugging, improves the detection efficiency, and can better cooperate with the rapid operation of the production line and reduce the possibility of production delays; (2) By setting a clamping component, the present invention can accurately position and fix the reducer at a predetermined position through its clamping force, avoids position deviation or shaking due to external force during the detection process, and ensures the accuracy of the detection data.
