Description

Technical Field

[0001] This utility model relates to the technical field of hollow shaft processing equipment, and specifically to a positioning device for hollow shaft processing. Background Technology

[0002] Hollow shafts, as a unique mechanical transmission component, are characterized by their hollow center, a stark contrast to solid shafts. Thanks to this unique design, hollow shafts can transmit torque and achieve rotational motion while also providing space for other components or allowing fluid flow, thus comprehensively optimizing the overall performance and layout of the equipment. Due to their distinctive structural characteristics, hollow shafts have found wide application in many fields, including wind power generation, shipbuilding, and industrial machinery.

[0003] Compared to solid shafts, the core feature of hollow shafts is their hollow central structure. While this characteristic brings many advantages, it inevitably affects their structural strength and rigidity. During machining and clamping, when subjected to outward or inward forces from the fixture, they may undergo a certain degree of deformation, thus affecting machining accuracy and quality. Therefore, we propose a positioning device for machining hollow shafts to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for machining hollow shafts, addressing the issue raised in the background section regarding the core characteristics of hollow shafts compared to solid shafts. While this feature offers numerous advantages, it inevitably impacts structural strength and rigidity. During machining and clamping, the shaft may deform to some extent under outward or inward forces from the clamping fixture, thus affecting machining accuracy and quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning device for machining hollow shafts includes a machining table. An installation tube is provided on the upper surface of the machining table, and an inner clamping component is provided on the lower surface of the machining table. Multiple outer clamping blocks are uniformly rotated around an axis on the outer side of the installation tube. A motor mounting seat is provided at the bottom of the inner clamping component. Multiple slider components are respectively provided at the bottom of the multiple outer clamping blocks. A motor clamping component is provided on the upper surface of the motor mounting seat, and multiple motor connecting rods are uniformly rotated around an axis on the top of the motor clamping component.

[0007] The inner clamping component includes a cylinder. The output end of the cylinder passes through the processing table and is fixedly connected to a connecting block. Multiple cylinder connecting rods are rotatably connected to the outer side of the connecting block around the axis. Multiple sliding rods are rotatably connected to the other ends of the multiple cylinder connecting rods. The other ends of the multiple sliding rods pass through the mounting tube and are fixedly connected to an inner clamping block.

[0008] Furthermore, the processing table includes a mounting plate, on which multiple sliding grooves are uniformly arranged to rotate around an axis, and multiple support rods are fixedly connected to both sides of the lower surface of the mounting plate.

[0009] Furthermore, the mounting tube is fixedly connected to the upper surface of the mounting plate, the outer side of the motor mounting base is fixedly connected to multiple support rods, the slider component includes a slider, the bottom of the slider is fixedly connected to a slider connecting rod through the mounting plate, and the slider is slidably connected to the mounting plate through a sliding groove.

[0010] Furthermore, the bottom of the multiple outer clamping blocks is fixedly connected to the top of the slider, the cylinder is fixedly connected to the lower surface of the mounting plate, the multiple sliding rods are slidably connected to the mounting tube, the motor clamping component includes a motor, the output end of the motor is fixedly connected to a rotating block, and the bottom of the motor is fixedly connected to the motor mounting base.

[0011] Furthermore, one end of each of the motor connecting rods is rotatably connected to the rotating block, and the other end of the motor connecting rod is rotatably connected to the slider connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a motor clamping component to drive multiple motor connecting rods, which in turn drive the outer clamping blocks on the top of multiple slider components to clamp the outer surface of the hollow shaft. Then, a cylinder pushes out the connecting block, which in turn drives multiple cylinder connecting rods to push out multiple slide rods along the mounting tube, thereby pushing out multiple inner push blocks. This can work in conjunction with multiple outer clamping blocks to better clamp the hollow shaft and can mutually cancel out the clamping force on the hollow shaft, preventing deformation of the hollow shaft and affecting the subsequent processing accuracy and quality.

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.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a positioning device for hollow shaft processing, including a processing table 1, an installation tube 2 on the upper surface of the processing table 1, an inner clamping component 3 on the lower surface of the processing table 1, a plurality of outer clamping blocks 4 uniformly rotated around the outer side of the installation tube 2, a motor mounting seat 5 at the bottom of the inner clamping component 3, a plurality of slider components 6 at the bottom of the plurality of outer clamping blocks 4, a motor clamping component 7 on the upper surface of the motor mounting seat 5, and a plurality of motor connecting rods 8 uniformly rotated around the top of the motor clamping component 7.

[0021] The inner clamping component 3 includes a cylinder 301. The output end of the cylinder 301 passes through the processing table 1 and is fixedly connected to a connecting block 302. The outer side of the connecting block 302 is evenly rotated around the axis and connected to multiple cylinder connecting rods 303. The other end of the multiple cylinder connecting rods 303 is rotatably connected to multiple sliding rods 304 respectively. The other end of the multiple sliding rods 304 passes through the mounting tube 2 and is fixedly connected to an inner top block 305.

[0022] The processing table 1 includes a mounting plate 101. Multiple sliding grooves 102 are uniformly arranged on the mounting plate 101 around an axis. Multiple support rods 103 are fixedly connected to both sides of the lower surface of the mounting plate 101. In this example, by setting the sliding grooves 102, multiple slider components 6 can slide stably, thereby driving multiple outer clamping blocks 4 to clamp the outer surface of the hollow shaft.

[0023] The mounting tube 2 is fixedly connected to the upper surface of the mounting plate 101. The outer side of the motor mounting base 5 is fixedly connected to multiple support rods 103. The slider component 6 includes a slider 601. The bottom of the slider 601 passes through the mounting plate 101 and is fixedly connected to a slider connecting rod 602. The slider 601 is slidably connected to the mounting plate 101 through the sliding groove 102. In this example, by setting the mounting tube 2, it is convenient to install the inner clamping component 3 to clamp the inner side of the hollow shaft.

[0024] Multiple outer clamping blocks 4 are fixedly connected to the bottom of the slider 601 at the top, cylinder 301 is fixedly connected to the lower surface of mounting plate 101, multiple sliding rods 304 are slidably connected to mounting tube 2, motor clamping component 7 includes motor 701, rotating block 702 is fixedly connected to the output end of motor 701, and the bottom of motor 701 is fixedly connected to motor mounting base 5.

[0025] One end of multiple motor connecting rods 8 is rotatably connected to the rotating block 702, and the other end of the motor connecting rods 8 is rotatably connected to the slider connecting rod 602.

[0026] Working principle: By aligning the hollow shaft with the mounting tube 2 and inserting it, the motor 701 drives the rotating block 702 to rotate, which in turn drives multiple motor connecting rods 8, which in turn drives multiple slider connecting rods 602, causing the top slider 601 to slide along the slide groove 102, which in turn drives multiple outer clamping blocks 4 to clamp the outer surface of the hollow shaft. During this process, the cylinder 301 pushes out the connecting block 302, which in turn drives multiple cylinder connecting rods 303, which in turn drives multiple sliding rods 304 to push out along the mounting tube 2, so that multiple inner top blocks 305 contact the inner wall of the hollow shaft and press against it.
