DETAILED DESCRIPTION

[0027] At present, the traditional guide column polishing and rust removal operation is generally divided into the following five steps:

[0028] Step 1: Move the guide pin with the elastic positioning sleeve removed to a polishing and rust removal operation position;

[0029] Step 2: Use white gauze to wipe the cylindrical surface around the guide column and the top surface to remove oil stains;

[0030] Step 3: Use an angle grinder to polish and remove rust from the cylindrical surface around the guide column and the upper top surface. This step uses a 7mm thick grinding wheel.

[0031] Step 4: Use an angle grinder to polish and remove rust from the oil groove of the guide column body. This step uses a 4mm thick grinding wheel;

[0032] Step 5: Check the guide column after polishing and rust removal to see whether the circumferential surface and the upper top surface of the guide column body have metallic luster. If the requirements are met, move the guide column to the transfer cart and push it to the flaw detection room for flaw detection.

[0033] However, statistics of 100 guide posts taken for sampling show that the total polishing and rust removal time is 13652 seconds, and the total polishing and rust removal time for the circumferential surface and top surface of the guide post body is 7409 seconds; the polishing and rust removal time for each guide post is 2.28 minutes. At present, the throughput capacity of the entire passenger car bogie maintenance production line is 4 vehicles / day, and the daily cycle is 5 vehicles / day. Each car has two bogies with a total of 16 guide posts, so the number of guide posts that need to be polished and rusted every day is 80, a total of 182.4 minutes, that is, the employees spend up to three hours a day on the single polishing and rust removal of the guide posts. Before polishing and rust removal of the guide post body, there are other process steps to be performed. The employees must first withdraw the anti-loosening wire on the guide post, remove the pressure plate bolts on the elastic positioning sleeve and remove the pressure plate; then withdraw the old elastic positioning sleeve on the column body, and some rusted ones need to be pressed back with a hydraulic press. After these steps are completed, the guide post body can be polished and rust removed. This results in low efficiency, which directly affects the productivity and work enthusiasm of employees.

[0034] In view of this, the present application proposes a guide post polishing and rust removal device, which can realize the automated operation of polishing and rust removal of the guide post body.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Please refer to Figures 1 to 11 , Figure 1 This is a schematic diagram of the structure of the guide post polishing and rust removal device provided by the present invention; Figure 2 for Figure 1 Internal schematic diagram of Figure 3 for Figure 1 The structural diagram of the middle tooling box; Figure 4 for Figure 1 Schematic diagram of the structure of the middle shaft box; Figure 5 for Figure 1 Schematic diagram of the structure of the middle top plate; Figure 6 for Figure 1 Schematic diagram of the structure of the middle rubber pad; Figure 7 for Figure 1 Schematic diagram of the structure of the grinding sleeve; Figure 8 for Figure 7 A schematic diagram of the structure from another angle; Fig. 9 for Figure 7 A structural schematic diagram from another angle; Fig.10 for Figure 7 A cross-sectional view of Fig.11 for Figure 1 Schematic diagram of the structure of the grinding bearing.

[0037] The present invention provides a guide post polishing and rust removal device, comprising a tool box 1, an axle box 2, a plurality of drive devices 3, a plurality of polishing and rust removal devices arranged in the same number as the drive devices 3, and a positioning mechanism. The tool box 1 is provided with an inner cavity, the axle box 2 is horizontally placed in the inner cavity to divide the inner cavity into two upper and lower cavities, all the drive devices 3 are installed in the lower cavity, the drive device 3 can be a motor, all the polishing and rust removal devices are installed in the upper cavity, each polishing and rust removal device is coaxially connected with each drive device 3 in a one-to-one correspondence through a coupling mechanism, each polishing and rust removal device is provided with a processing chamber for placing the guide post, and a wire brush is installed on the circumference and bottom surface of the processing chamber, and each polishing and rust removal device performs rotary polishing and rust removal on the side circumference and top surface of the guide post inside the processing chamber under the power of its corresponding drive device 3. In addition, an industrial dust collector 5 is provided outside the tool box 1, and the industrial dust collector 5 is connected to the upper cavity of the tool box 1, and the removed rust residue is blown to the inside of the industrial dust collector 5 through a pipeline 4 for collection.

[0038] The staff will invert the eight guide pillars 180° and place them in the workpiece placement position in advance. The top surface of the guide pillar base will fit on the positioning pin platform. The eight guide pillars will be on the same horizontal plane, which means that the guide pillars have been installed in the correct position. Then press the start button, and the tooling will polish and remove rust from the surface of the guide pillars. After a period of time, the equipment will automatically stop working, and the polishing and rust removal of the eight guide pillars will be completed. The surface of the pillars will leak a metallic luster. During this operation, dust and rust residue will be automatically collected in the industrial dust collector 5, which also avoids the situation where dust is everywhere at the work site. Finally, the staff will take out the eight guide pillars that have been rust-removed at one time and move them to a flatbed cart for transportation to the flaw detection room for flaw detection. After completing the daily production task, employees need to clean the upper surface of the tooling, and then regularly remove the dust from the dust storage box in the industrial dust collector 5.

[0039] The working principle of this application is as follows: the employee turns the 8 guide pillars 180 degrees and puts them into the specified grinding holes. The polishing and rust-removing sleeves inside the tooling polish and rust-removes the surface of the guide pillars. The power comes from the motor below. After working for a period of time, the 8 guide pillars have completed the rust removal operation and the employee can take them out at one time.

[0040] Taking a tool as an example, eight guide pillars can be polished and rust-removed each time. It takes about 240 seconds to transport, install and remove the guide pillars, and the important polishing and rust-removal work is handed over to the tool, which takes about 30 seconds. Taking safety into consideration and the complete dust collection of the dust removal device, the dust removal device will start 10 seconds before the front motor starts, and will stop 10 seconds after the motor stops, so as to achieve one-button rust removal. Therefore, the tooling works once for 50 seconds, that is, the operation time for polishing and rust-removing eight guide pillars each time is 290 seconds. The daily cycle is 2,900 seconds for five vehicles, which only takes 48.3 minutes, accounting for 27% of the previous operation time, saving a lot of time and improving production efficiency.

[0041] When using the polishing and rust removal tooling of the present application, the worker's only operation is to move the guide column to the tooling table, position it in the required position and press the start button. The tooling will automatically stop after the operation is completed. The operation is simple and convenient, and the efficiency is high.

[0042] Please refer to Figure 3 The tooling box 1 includes a frame 11, a motor mounting plate 12, three side sealing plates 13, a top plate 14 and a rubber pad 15. The motor mounting plate 12 is used to fix the drive device 3. The side sealing plates 13 can be fixedly mounted on the three sides of the frame 11 by bolts, etc. The top plate 14 can be placed on the top surface of the frame 11 or installed on the top surface by bolts. The rubber pad 15 is laid on the top plate 14, and the number of rubber pads 15 and the drive device 3 is equal. Preferably, at least one side of the side sealing plate 13 is provided with multiple rows of ventilation holes 131 at the top of the upper cavity to accelerate the heat dissipation of the inner cavity.

[0043] The tooling box 1 is the basis of the entire rust removal and cleaning device. It is the installation area composed of the motor and the polishing and rust removal device. There needs to be enough space within the boundary range. On the other hand, it must be placed normally at the production site. Preferably, the tooling box 1 is kept as small as possible in length and width directions while meeting working conditions, providing employees with an appropriate working height and reducing fatigue at work.

[0044] In one embodiment, the guide posts are placed on the tooling box 1 in a 4×2 array, with 4 in the length direction and 2 in the width direction. The guide post base size is 258×258mm, at least 1032mm in the length direction. Since sufficient hand-held safety distance needs to be left, the length dimension is set to 1500mm. Similarly, the width dimension is set to 820mm. In the height direction, sufficient space must be left for the installation of the motor, the shaft box 2, the coupling mechanism, and the polishing and rust removal device, and the height of the guide posts should not be too high when installed. After comprehensive consideration, the height dimension is set to 850mm. The height of the guide posts after installation is about 1000mm. Therefore, the tooling dimensions length×width×height are 1500×820×850mm.

[0045] The frame 11 is the main supporting foundation and bears the main pressure. The frame 11 is preferably made of 60×60mm rectangular tube spot welding. Reinforcement ribs are set in the middle part, and the reinforcement ribs are made of 80×80mm rectangular tube electric welding. The reinforcement ribs are distributed in the center line position around the tooling, and an 810×355mm reinforcement rib frame is also arranged in the middle of the interior to serve as the installation support frame 11 for the motor and the shaft box 2. The side sealing plates 13 around and on the bottom surface are connected to the frame 11 by bolts to achieve a sealed connection, so that the internal facility components can be sealed and protected and dust and rust can be prevented from leaking out. There is a gap of 50mm between the bottom surface of the box and the ground (that is, there are corner supports of 50mm height at the four corners of the box), which is convenient for adjusting the box and for forklift handling and placement.

[0046] The above-mentioned coupling mechanism includes a connecting shaft, a torquer for connecting the driving device 3 and the connecting shaft, an upper flange bearing seat and a lower flange bearing seat mounted on the connecting shaft, and the upper flange bearing seat and the lower flange bearing seat are both installed inside the shaft box body 2. Therefore, when the motor is transported, the rotational force is transmitted to the polishing and rust removal device through the torquer and the connecting shaft. When the polishing and rust removal device rotates, the internal wire brush removes rust and polishes the side and bottom surfaces of the guide column.

[0047] The shaft box body 2 is a rectangular shell structure with an open front end and closed sides and upper and lower surfaces. It includes a flange bearing seat with a plurality of bearing mounting holes 21 and bearings pre-installed in each bearing mounting hole 21. The main function of the shaft box body 2 is to install bearings to support the connecting shaft. Secondly, the rust removal area is separated from the power area of ​​the lower part, so that rust residue and dust are isolated in the rust removal area to prevent dust from drifting to the power area of ​​the lower part. The flange bearing seat and the bearing are installed as a whole to avoid dust and rust residue falling into the bearing rollers during the polishing and rust removal process, causing poor lubrication and thus damaging the bearings.

[0048] In order to make the connecting shaft completely concentric during rotation, two bearings need to be arranged in the axial direction for support. The upper and lower surfaces of the shaft box body 2 are equipped with flange bearing seat mounting holes at the corresponding bearing mounting positions. Such an arrangement can ensure that the runout of the connecting shaft is within the specified range during the polishing and rust removal process, making it completely concentric and increasing the service life of the bearing.

[0049] The polishing and rust removal device includes a grinding sleeve 6 and a grinding bearing 7. The grinding sleeve 6 is provided with a processing chamber. The inner wall of the grinding sleeve 6 is provided with four circumferentially distributed wire brush grooves 61. Preferably, each wire brush groove 61 is an I-shaped groove. A wire brush is installed in each wire brush groove 61. The wire brush is a wire brush commonly used in grinding and polishing. It has high hardness and high wear resistance. The wire brush is in a relatively fluffy state and can polish and remove rust from the oil groove on the surface of the guide column body at the same time.

[0050] The grinding sleeve 6 is provided with a plurality of slag discharge holes 62 distributed circumferentially, and the bottom surface of the processing chamber is provided with a bottom brush fixing hole 63; the grinding bearing 7 is provided with a stepped sleeve, the lower end of the sleeve is arranged in the processing chamber, the upper end of the sleeve is provided with a flat plate, and the four corners of the flat plate are provided with positioning holes. After the sleeve passes through the tooling box 1, it is connected to the rubber pad 15 by a positioning pin to prevent the guide column from rotating when the tooling is in operation.

[0051] The guide column is flipped 180° and placed upside down in the mounting holes of the grinding bearing 7 and the grinding sleeve 6. Therefore, there are a total of 32 locating pins on the upper top mounting platform. It should be ensured that there is enough space for the operator to safely install the guide column. The mounting platform surfaces of the 32 locating pin bases are on the same horizontal plane to ensure that the eight installed guide columns remain completely level.

[0052] The mounting hole can facilitate the replacement of consumable cleaning wire brushes and the placement of guide posts. After the guide posts are placed, there will be a gap, which will cause rust and dust to overflow. In order to prevent the overflow of rust and dust, a damping plate is placed on the mounting hole. On the one hand, it is for the installation of the guide post, and on the other hand, it is to limit the axial swing of the guide post. The inner diameter of the damping plate must match the diameter of the guide post base. Holes of the same size as the base of the positioning pin are also left at the four corners of the damping plate, so as to achieve the positioning installation of the damping plate. In this way, when replacing the cleaning wire brush, you only need to remove the damping plate, and then replace the consumables through the mounting holes on the mounting platform.

[0053] The polishing and rust removal sleeve is cylindrical barrel-shaped, and four wire brush chutes 61 are arranged at equal angles (90°) on the inner wall. The size of the chutes is 20×20×100mm. In order to facilitate the installation and replacement of wire brushes, the cleaning sleeve wall thickness is 15mm, and a 6mm polishing and rust removal area is left around the guide column after the wire brush is installed by the chutes. Preferably, there is a 3mm interference between the wire brush and the guide column body to achieve sufficient polishing and rust removal operations.

[0054] In addition, in order to allow dust and rust residue to be discharged to the outside of the polishing sleeve 6 in a timely and smooth manner during the polishing and rust removal process, a number of waist-shaped holes distributed circumferentially are opened on the polishing and rust removal sleeve. The dust and rust residue are automatically discharged by the vortex formed by rotation during the polishing and rust removal process, and then the dust and rust residue are sucked out by an industrial dust collection device. Preferably, the waist-shaped holes are opened at equal angles and there are four of them. The hole type is waist-shaped holes, and each wire brush chute 61 and each slag discharge hole 62 are spaced apart. A wire brush is also installed on the lower bottom surface of the polishing sleeve 6 to polish and remove rust on the top surface of the column. The wire brush is installed in a fixed hole manner, and the bottom of the polishing sleeve 6 is connected to the connecting shaft to realize the transmission of torque, so that the polishing sleeve 6 rotates, thereby achieving the effect of polishing and rust removal on the guide column.

[0055] All the above motors are three-phase AC asynchronous motors, which are installed horizontally. The motors have their own bases, no direct mounting flanges, and no flanges on the front cover. The motor shaft and the connecting shaft are connected by a coupling, which can also compensate for the offset (including axial offset, radial offset, angular offset or combined offset) between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, etc., and mitigate impact and absorb vibration.

[0056] One end of the connecting shaft is connected to the motor by a coupling, and the other end is connected to the grinding sleeve 6, so as to realize the transmission of power. A cylindrical pin is used for connection here, a pin hole is provided at the upper end of the connecting shaft, and a pin hole of the same size is also left at the lower part of the grinding sleeve 6. The cylindrical pin is fixed in the pin hole by a slight interference fit to achieve the purpose of connection.

[0057] The rust residue and dust generated by polishing and rust removal need to be processed and cannot be directly discharged into the workplace. Therefore, a device is needed to collect and process the dust and rust residue in a centralized manner. The industrial dust collector 5 is selected here, and the cabinet structure is convenient for on-site placement and transportation. It consists of a high-suction motor, an air inlet, an air outlet, a non-woven filter, a dust storage box and other parts. There is a dust storage box under the dust collector to collect the dust and rust residue sucked into the dust collector, which is convenient for centralized collection and processing. Employees only need to open the dust storage box drawer regularly to clean the dust and rust residue accumulated inside.

[0058] The working principle of this industrial dust collector 5 is roughly as follows: the gas containing rust, slag and dust enters the box through the air inlet, is filtered by the filter, and the dust is retained on the surface of the filter. The purified air is discharged to the outside of the box through the air outlet by the fan, and can be directly discharged outside the equipment. The dust on the filter will automatically fall into the dust storage box due to the action of the fan, and employees need to clean it regularly. However, as the host continues to work, the dust adhering to the surface of the filter will continue to increase, causing the equipment resistance to continue to rise. For this reason, it is necessary to clean it regularly, and the dust adhering to the filter will fall into the dust storage box and be removed.

[0059] The guide column polishing and rust removal device provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
