Description

Technical Field

[0001] This utility model belongs to the technical field of rail transit automation equipment, and relates to an online through-type loading and unloading device for a wheel boring machine, and more particularly to an online through-type loading and unloading device applied to a railway wheel hub hole boring machine. Background Technology

[0002] Wheel boring machines are commonly used for semi-finishing and finishing of railway wheel hub holes. They offer high machining accuracy, good machining quality, and high production efficiency. However, the structure of wheel boring machines, which uses a spindle box and CNC rotary table, makes it inconvenient for manual loading and unloading of wheels. To meet the demands of automated and high-efficiency production, wheel robots are now widely used for loading and unloading wheel boring machines. Wheel robots require a large amount of installation and operating space, and cannot be installed or used in environments with insufficient space.

[0003] Therefore, there is a need for an automatic loading and unloading device for wheel boring machines that occupies little space, has a high degree of automation, high integration, and is highly efficient and reliable. Utility Model Content

The technical solution adopted by this utility model is: an online through-type loading and unloading device for a wheel boring machine, comprising: a main support, a power unit, a lifting device, and a conveying device. The conveying device is disposed on both sides of the main support, the lifting device is connected to the bottom of the main support and can drive the main support 1 to move vertically up and down, and the power unit drives the conveying device to rotate.

[0005] Furthermore, the conveying device includes a conveyor chain, a transmission chain, a driven sprocket, a sprocket shaft, and a driving sprocket; a sprocket shaft is provided at the front end of the main support, and first sprockets are provided at both ends of the sprocket shaft; a driven sprocket is provided at the rear end of the main support; one end of the conveyor chain is connected to the first sprocket, and the other end is connected to the driven sprocket.

[0006] A second sprocket is also provided on the sprocket shaft, and the drive sprocket and the second sprocket are connected by a transmission chain.

[0007] Furthermore, the power unit is a geared motor, which is installed on one side of the main support. The output shaft of the geared motor is connected to the drive sprocket. The power output by the geared motor drives the drive sprocket to rotate the transmission chain, and then transmits the power to the sprocket shaft to drive the conveyor chain to rotate forward or backward.

[0008] Furthermore, the lifting device is a hydraulic cylinder mounted on the base. The hydraulic cylinder includes a cylinder body and a piston rod. The cylinder body is fixed relative to the base. The end of the piston rod of the hydraulic cylinder is connected to the main support. When the piston rod extends, it pushes the main support to rise.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] See Figures 1-5 One embodiment of this utility model discloses an online through-type loading and unloading device for a wheel boring machine, comprising:

[0019] 1. Main support; 2. Conveyor chain; 3. Drive chain; 4. Driven sprocket; 5. Sprocket shaft; 6. Gear motor; 7. Drive sprocket; and 8. Base.

[0020] A sprocket shaft 5 is provided at the front end of the main support 1, and a first sprocket 51 is provided at both ends of the sprocket shaft 5. A driven sprocket 4 is provided at the rear end of the main support 1. One end of the conveyor chain 2 is connected to the first sprocket 51, and the other end is connected to the driven sprocket 4.

[0021] The sprocket shaft 5 is also equipped with a second sprocket 52. The drive sprocket 7 and the second sprocket 52 are connected by a transmission chain 3. The reduction motor 6 is located on one side of the main support 1. The output shaft of the reduction motor 6 is connected to the drive sprocket 7. The power output by the reduction motor 6 drives the drive sprocket 7 to rotate the transmission chain 3, and then transmits it to the sprocket shaft 5 to drive the conveyor chain 2 to rotate forward or backward.

[0022] A hydraulic cylinder 9 is installed on the base 8. The hydraulic cylinder 9 includes a cylinder body and a piston rod. The cylinder body is fixed relative to the base 8. The end of the piston rod of the hydraulic cylinder 9 is connected to the main support 1. When the piston rod extends, it pushes the main support 1 to rise. When the piston rod of the hydraulic cylinder 9 retracts, the main support 1 descends.

[0023] In the working state, the base 8 is symmetrically spanned across the worktable 11. The base 8 is connected to the main support 1 through the linear guide pair 10, so that the main support 1 can be raised and lowered relative to the base 8. The main support 1 is made of welded steel profiles, and it is equipped with a support platform to support the conveyor chain 2 and has multiple mounting seats and mounting holes. The conveyor chain 2 is symmetrically arranged on both sides of the main support 1.

[0024] The sprocket shaft 5 is supported by multiple sets of bearings and installed in the mounting hole at the front end of the main bracket 1; the driven sprocket 4 is supported by bearings and symmetrically installed in the mounting hole at the rear end of the main bracket 1.

[0025] The working principle of the loading and unloading device 100: The piston rod of the hydraulic cylinder 9 extends and pushes the main support 1 to rise, so that the conveyor chain 2 is connected to the conveyor line 13 before and after the wheel boring machine station. The wheel 12 is transported to the top of the conveyor chain 2 through the front conveyor line 13. At the same time, the reduction motor 6 drives the conveyor chain 2 to rotate, and transports the wheel 12 to the middle of the worktable 11. The piston rod of the hydraulic cylinder 9 retracts and drives the main support 1 to descend. The wheel 12 then falls onto the support of the worktable 11. After processing is completed, the piston rod of the hydraulic cylinder 9 extends again and pushes the main support 1 to rise. The reduction motor 6 drives the conveyor chain 2 to rotate and sends the wheel 12 out to the rear conveyor line 13.

[0026] It should be understood that the power device involved in this utility model includes, but is not limited to, the geared motor 6, and may also be an engine, electric motor, or other device capable of outputting power; the lifting device includes, but is not limited to, the hydraulic cylinder 9, and may also be a gear rack, worm gear, or other mechanical device; the transmission device is not limited to chain drive, for example, belt drive can also achieve the same purpose. This utility model can be adapted to various models of wheel boring machines and can also be connected to the electrical and hydraulic systems of wheel boring machines for centralized control.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
