Description

An encoder shaft straightening fixture Technical Field

[0001] This utility model relates to the field of encoder shaft straightening fixture technology, specifically an encoder shaft straightening fixture. Background Technology

[0002] In the field of industrial automation, encoders serve as crucial motion control devices for precise positioning, measurement, and feedback. With increasing levels of industrial automation, the requirements for encoder accuracy and reliability are also rising. The straightness and coaxiality of the encoder shaft directly affect its measurement accuracy and stability. If the shaft is bent or eccentric, it will increase the error in the encoder's output signal and may even affect the performance of the entire control system. Traditional shaft straightening methods often suffer from problems such as cracks and overshoot, making it difficult to meet the straightening requirements of high-precision encoders. Therefore, developing an efficient and accurate shaft straightening device and technology has become an urgent industry need.

[0003] In the existing encoder shaft straightening process, the shaft needs to be manually inserted into the device for straightening, and it still needs to be manually removed after straightening. When straightening some small encoder shafts, it is difficult to manually grasp them because the shafts are small. Therefore, we propose an encoder shaft straightening fixture to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide an encoder shaft core straightening fixture to solve the problem that the encoder shaft core straightening fixture mentioned in the background art is inconvenient for automatic loading and unloading of shaft cores.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an encoder shaft core straightening fixture, including a base;

[0006] The base has fixed seats at both ends of the top. Rotating shafts are rotatably provided on both sides of the two sets of fixed seats. A drive wheel is installed at the front end of the rotating shaft. Three sets of housings are provided between the two sets of fixed seats at the top of the base. Two sets of first cylinders are provided at the bottom of each of the three sets of housings. A support seat is slidably provided inside the housing. The output end of the first cylinder is connected to the bottom of the support seat. A detection component is provided above the base. A feeding component is provided above the base.

[0007] The feeding assembly includes a drive trough, a drive chamber, pneumatic grippers, and a straightening block. Hydraulic rods are located at the top of the four corners of the base. The output ends of the hydraulic rods are connected to the drive trough. Two sets of sliders are slidably mounted within the drive trough, and the two sets of sliders are connected via the drive chamber. A moving block is slidably mounted on the surface of the drive chamber. A moving assembly is located within the drive chamber to move the moving block. An assembly plate is located on the left side wall of the moving block, and pneumatic grippers are located at both ends of the bottom of the assembly plate. An installation block is located on the right side wall of the moving block, and a straightening block is detachably mounted below the installation block.

[0008] As a preferred technical solution of this utility model, the detection component includes a detection rod, a frame, a connecting rod, and a sensor. A detection rod is provided in the middle of the two adjacent sets of housings. Two sets of frames are provided on the right side of the housing. A connecting rod is hinged to the middle of the upper part of the two sets of frames. A sensor is provided at the front end of each of the two sets of connecting rods. Each of the two sets of sensors is connected to the corresponding detection rod in front.

[0009] As a preferred technical solution of this utility model, the tail end of the connecting rod is provided with a push rod that slides through it, and the top of the base is provided with a second cylinder, the output end of the second cylinder being connected to the bottom of the push rod.

[0010] As a preferred embodiment of this utility model, the base is provided with multiple sets of limiting rods on both sides of its top.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this encoder shaft core straightening fixture, the shaft core is gripped by a pneumatic clamping claw, and the drive screw rotates to move the drive chamber. After the shaft core is placed at the center position of the two drive wheels, the first cylinder is driven to make the detection rod contact the bottom of the shaft core. The drive wheel then drives the shaft core to rotate. During the rotation of the shaft core, the detection rod and sensor work together to detect the shaft core. After the detection is completed, the shaft core is straightened by the straightening block and the support seat. After the straightening is completed, the shaft core is gripped again by the pneumatic clamping claw and moved backward. The above operation is repeated to continuously straighten the shaft core and automatically load and unload it, avoiding the inconvenience of manual loading and unloading due to the small size of the shaft core.

[0022] 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.

[0023] Please refer to Figures 1-6. This utility model provides a technical solution: an encoder shaft core straightening fixture, including a base 1. Fixed seats 2 are provided at both ends of the top of the base 1. Rotating shafts 3 are rotatably mounted on both sides of the two sets of fixed seats 2. Drive gears 19 are installed on both sets of rotating shafts 3, and the two sets of drive gears 19 mesh with each other. A drive wheel 4 is installed at the front end of the rotating shaft 3. Three housings 5 ​​are provided between the two sets of fixed seats 2 at the top of the base 1. Two sets of first cylinders 6 are provided at the bottom of each of the three sets of housings 5. A support seat 7 is slidably provided inside the housing 5. The output end of the first cylinder 6 is connected to the bottom of the support seat 7. A detection component 8 is provided above the base 1. The measuring component 8 includes a detection rod 801, a frame 802, a connecting rod 803, and a sensor 804. Detection rods 801 are provided in the middle of two adjacent sets of housings 5. Two sets of frames 802 are provided on the right side of housing 5. Connecting rods 803 are hinged at the middle of the upper part of the two sets of frames 802. Sensors 804 are provided at the front end of the two sets of connecting rods 803. The two sets of sensors 804 are connected to the corresponding detection rods 801 in front. A top rod 16 is slidably provided through the tail end of the connecting rod 803. A second cylinder 17 is provided at the top of the base 1. The output end of the second cylinder 17 is connected to the bottom of the top rod 16. A feeding component 9 is provided above the base 1.

[0024] Multiple second cylinders 17 drive the push rod 16 to move, so that the push rod 16 drives the sensor 804 to adjust its angle through the hinge shaft, so that the front detection rod 801 rises and contacts the bottom of the shaft core. At this time, the motor starts and drives the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the drive gear 19 above to rotate. Since the drive gears 19 on both sides mesh with each other, they rotate and drive the shaft core to rotate. When the shaft core is distorted, the detection rod 801 will move during the rotation. The detection rod 801 will then prompt the sensor 804. At this time, after the drive wheel 4 stops rotating, the detection rod 801 will reset. Then, the first cylinder 6 drives the support seat 7 to rise and contact the bottom of the shaft core, supporting the shaft core.

[0025] The feeding assembly 9 includes a drive trough 901, a drive chamber 902, a pneumatic gripper 903, and a straightening block 904. Hydraulic rods 20 are located at the top of the four corners of the base 1. The output ends of the hydraulic rods 20 are connected to the drive trough 901. Slider blocks 10 are slidably arranged within the two sets of drive troughs 901, and the two sets of sliders 10 are connected via the drive chamber 902. Moving blocks 12 are slidably arranged on the surface of the drive chamber 902. A moving assembly 13 for moving the moving blocks 12 is located within the drive chamber 902. The moving assembly 13 includes a rotating rod 131, a first gear 132, a rack 133, and a moving groove 134. The rotating rod 131 is rotatably arranged within the moving block 12, and a first gear 132 is mounted on the rotating rod 131. Gear 132, rack 133 meshing with first gear 132 is provided on the inner walls of both sides of drive chamber 902, moving groove 134 adapted to rotating rod 131 is provided on the surface of both ends of drive chamber 902, mounting plate 14 is provided on the left side wall of moving block 12, pneumatic clamping claw 903 is provided at both ends of the bottom of mounting plate 14, mounting block 15 is provided on the right side wall of moving block 12, straightening block 904 is detachably installed below mounting block 15, multiple sets of limiting rods 18 are provided on both sides of the top of base 1, the limiting rods 18 are slidably connected to drive chamber 901, lead screw 11 is rotatably provided in drive chamber 901 on the front side of base 1, and lead screw 11 is threadedly connected to slider 10 inside drive chamber 901 on the same side;

[0026] In use, the pneumatic clamping claw 903 clamps the shaft core, and the motor drives the lead screw 11 to move the slider 10 inside the drive groove 901, simultaneously moving the drive chamber 902. This positions the clamped shaft core between the two drive wheels 4. The hydraulic rod 20 then lowers the drive groove 901, placing the shaft core between the drive wheels 4. The motor then drives the rotating rod 131 to rotate, synchronously driving the first gear 132 to rotate. Since the first gear 132 meshes with the rack 133, it moves the moving block 12 forward. The shaft moves while the rotating rod 131 moves inside the moving groove 134 on the surface of the drive chamber 902. After moving the straightening block 904 below the mounting block 15 in front of the moving block 12 to the position to be straightened, the hydraulic rods 20 on both sides drive the drive chamber 901 to descend, causing the straightening block 904 to descend and cooperate with the support seat 7 below to complete the straightening. After the straightening is completed, the pneumatic clamping claw 903 is activated again to clamp the shaft core and move the straightened shaft core to the rear placement position. Then, a new shaft core is gripped again for straightening.

[0027] Working principle: When using the encoder shaft straightening fixture, the pneumatic clamping jaws 903 clamp the shaft, and the motor drives the lead screw 11 to move the slider 10 inside the drive groove 901, simultaneously moving the drive chamber 902. This positions the clamped shaft between the two drive wheels 4. The hydraulic rod 20 then lowers the drive groove 901, placing the shaft between the drive wheels 4. Multiple second cylinders 17 move the push rods 16, causing the sensor 804 to adjust its angle via the hinge shaft. This raises the detection rod 801 to contact the bottom of the shaft. The motor then starts, rotating the rotating shaft 3, which in turn rotates the drive gear 19 above. Since the drive gears 19 mesh, their rotation causes the shaft to rotate. When the shaft becomes distorted, the detection rod 801 moves during rotation, alerting the sensor 804. At this point, the drive wheels 4... After the rotation stops and the detection rod 801 resets, the first cylinder 6 drives the support seat 7 to rise and contact the bottom of the shaft core, supporting the shaft core. Then, the motor drives the rotating rod 131 to rotate synchronously, driving the first gear 132 to rotate. Since the first gear 132 meshes with the rack 133, it drives the moving block 12 to move. At the same time, the rotating rod 131 moves inside the moving groove 134 on the surface of the drive chamber 902, moving the straightening block 904 below the mounting block 15 in front of the moving block 12 to the position that needs to be straightened. Then, the hydraulic rods 20 on both sides drive the drive groove 901 to descend, causing the straightening block 904 to descend and cooperate with the support seat 7 below to complete the straightening. After the straightening is completed, the pneumatic clamping claw 903 is activated again to clamp the shaft core and move the straightened shaft core to the rear placement position. Then, a new shaft core is gripped and straightened again, thus completing a series of operations.
