Description

Technical Field

[0001] This application relates to the technical field of bolster processing, and specifically to a bolster processing device. Background Art

[0002] Among the key components of railway freight cars, the bolster plays a crucial role. It is responsible for connecting the bogie and the wheels, and bearing and transmitting the vertical load from the car body and various dynamic forces during operation. With the continuous increase in the requirements of the railway transportation industry for the load-bearing capacity, running stability, and safety of freight cars, the processing quality and efficiency of the bolster have become the focus of attention. In the current processing process of the bolster, the machine tool undertakes two key and complex tasks of cutting and punching.

[0003] For example, the patent with the publication number CN210160719U discloses an integrated cutting and punching numerically controlled machine tool. It includes the settings of a machine tool base, a motor, a machine tool box, a driving wheel, a main transmission wheel, a drill bit clamping mechanism, a driving motor, and a cutting tool, so as to directly perform punching work on the workpiece after cutting.

[0004] After the above-mentioned patent machine tool performs cutting and punching operations on the bolster, the waste material will scatter and accumulate on the machine tool workbench after separating from the bolster main body. Similarly, during the punching operation, the debris drilled by the high-speed rotating drill bit, such as powder or short columns, will also fall onto the surface of the workbench. As the processing continues, the waste material accumulates continuously and gradually covers the workbench. Therefore, when a new bolster is placed on the workbench for processing, the waste material will pad under the bolster, preventing it from fitting precisely with the workbench and causing deviation in the positioning of the bolster. Therefore, it is necessary to provide a bolster processing device to solve the above problems.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] Such as Figures 1-5As shown in the figure, the present application provides a carrier saddle processing device, including a machine tool 1. The machine tool 1 includes a housing 11, and there is a working chamber 12 on the housing 11. A dust cover 13 is slidably mounted on the housing 11. The dust cover 13 is used to prevent waste chips generated during processing from splashing everywhere. It should be noted that this sliding method can be achieved by fixedly installing a slide rail on the housing 11 and providing a sliding block adapted to the slide rail on the dust cover 13, so that the dust cover 13 slides on the housing 11;

[0029] A perspective window 14 is provided on the dust cover 13, which is convenient for the staff to view the processing situation of the carrier saddle. A handle 15 is fixedly installed on the dust cover 13, which is convenient for pushing the dust cover 13 to move on the housing 11;

[0030] A first fixing plate 16 is fixedly installed on the inner wall of the working chamber 12, and a processing component 2 is installed on the first fixing plate 16. The processing component 2 includes a cutting unit installed on the first fixing plate 16. The cutting unit includes a first cylinder 21 fixedly installed on the first fixing plate 16, a fixed seat 22 fixedly installed at the output end of the first cylinder 21, a first motor 24 fixedly installed on the fixed seat 22, and a saw blade 25 fixedly installed at the output end of the first motor 24. At the same time, a splash guard 23 is fixedly installed on the side of the first motor 24 close to the saw blade 25. The saw blade 25 is adapted to rotate with the output end of the first motor 24 to process the carrier saddle. At the same time, the first motor 24 is adapted to move with the telescopic end of the first cylinder 21 to approach or move away from the carrier saddle;

[0031] A punching unit is installed on the inner wall of the working chamber 12 on the same side as the first fixing plate 16. The punching unit includes a first moving unit installed on the inner wall of the working chamber 12. The first moving unit includes a second fixing plate 211 fixedly installed on the inner wall of the working chamber 12. Two groups of guide rails 26 are fixedly installed on the second fixing plate 211. A first sliding plate 27 is slidably installed between the two groups of guide rails 26. A second motor 210 is fixedly installed on the first sliding plate 27. A lead screw 28 is fixedly installed at the output end of the second motor 210. The first sliding plate 27 is threadedly connected to the lead screw 28. A limiting plate 29 is fixedly installed at the end of the first sliding plate 27 away from the second motor 210. One end of the lead screw 28 is connected to the limiting plate 29 by a bearing;

[0032] The second motor 210 is adapted to rotate to drive the lead screw 28 to rotate, so that the first sliding plate 27 slides along the linear direction of the guide rail 26;

[0033] And a second moving component 212 is installed on the first sliding plate 27. The second moving component 212 has a similar structure to the first moving unit. Here, the first sliding plate 27 of the second moving component 212 is defined as the second sliding plate. A third motor 213 is fixedly installed on the second sliding plate. A drill bit (not shown in the figure) is fixedly installed at the output end of the third motor 213. The drill bit is adapted to rotate along with the output end of the third motor 213 to process the carrying saddle;

[0034] When it is necessary to drill the carrying saddle, first start the first moving unit in the drilling unit. In the first moving unit, the second motor 210 starts to rotate, and its output end drives the lead screw 28 to rotate synchronously. The rotation of the lead screw 28 is converted into the linear sliding of the first sliding plate 27 along the guide rail 26 to adjust the position of the first sliding plate 27 on the guide rail 26, so as to move the second moving component 212 installed on the first sliding plate 27 to the general area where the carrying saddle needs to be drilled;

[0035] Then start the second moving component 212. Since the second moving component 212 has a similar structure to the first moving unit, when the internal motor (similar to the second motor 210 of the first moving unit) works, it will drive the second sliding plate to slide. In this way, the position of the third motor 213 installed on the second sliding plate and the drill bit at its output end can be further fine-tuned to accurately align the drill bit with the specific position on the carrying saddle where drilling is required. Then start the third motor 213 to drive the drill bit to rotate at a high speed, and the carrying saddle can be accurately drilled through the drill bit;

[0036] And an installation component 4 is installed inside the working chamber 12. The installation component 4 is used to adjust the position of the carrying saddle. The installation component 4 includes an installation base 41 fixedly installed inside the working chamber 12. A third moving component 42 is fixedly installed on the side of the installation base 41. The third moving component 42 has a similar structure to the first moving component. Here, the first sliding plate 27 of the third moving component 42 is defined as the third sliding plate. A fourth moving component 43 is installed on the third sliding plate. The fourth moving component 43 has a similar structure to the first moving component. Here, the first sliding plate 27 of the fourth moving component 43 is defined as the fourth sliding plate 514. A guiding portion 44 is fixedly installed on the side of the fourth sliding plate 514. The guiding portion 44 is used to guide the falling of waste materials;

[0037] And a collecting assembly 5 is installed on the fourth slide plate 514. The collecting assembly 5 includes a right-angle plate 57 fixedly installed on the side of the fourth slide plate 514, and a first rotating shaft 55 is movably installed on the right-angle plate 57. A discharging plate 515 is fixedly installed on the first rotating shaft 55. The discharging plate 515 has a discharging groove (not marked in the figure, and the discharging groove is used for placing the saddle. And second cylinders 53 are fixedly installed at positions near both ends of the discharging plate 515, and clamping parts 54 are fixedly installed at the telescopic ends of the second cylinders 53. The clamping parts 54 are adapted to move along with the telescopic ends of the second cylinders 53 to clamp and fix the saddle, so as to facilitate cutting and punching operations;

[0038] It should be noted that the third moving assembly 42 is adapted to drive the saddle to move horizontally, that is, to move the saddle to a position below the cutting unit or the punching unit, while the fourth moving assembly 43 can drive the saddle to move to a precise position where the cutting unit or the punching unit needs to be adjusted, that is, to adjust the vertical position of the saddle (refer to Figure 5 ;

[0039] And a first bevel gear 56 is fixedly installed at one end of the first rotating shaft 55. At the same time, a second rotating shaft (not marked in the figure) is installed on the right-angle plate 57 by bearings. A second bevel gear 59 is fixedly installed on the second rotating shaft. The second bevel gear 59 meshes with the first bevel gear 56. And a gear part 58 is fixedly installed on the second rotating shaft. At the same time, a fixing frame 510 is fixedly installed on the inner wall of the housing 11. The fixing frame 510 is concave, and a first rack 511 is fixedly installed at the top end of the inner wall of the fixing frame 510, and a second rack 512 is fixedly installed at the bottom end of the inner wall of the fixing frame 510. The first rack 511 and the second rack 512 both have smooth parts;

[0040] It should be noted that the number of tooth blocks on the first rack 511 and the second rack 512 is the same. At the same time, the first rack 511 is close to the gear part 58 in the initial state. And when the gear part 58 successively crosses the first rack 511 and the smooth part on the first rack 511, at this time, the discharging plate 515 is between the cutting unit and the punching unit, and at the same time, the discharging plate 515 is in an inclined state of rotating 30 degrees along the first rotating shaft 55, so as to dump the waste accumulated on the discharging plate 515. And when the gear part 58 gradually approaches and crosses the second rack 512 and the smooth part on the second rack 512, at this time, the discharging plate 515 rotates 30 degrees in the reverse direction along the first rotating shaft 55 and returns to the horizontal state;

[0041] And a collection component 5 is installed at the bottom of the outer shell 11. The collection component 5 includes a collection box 51 fixedly installed at the bottom of the outer shell 11, which is used to collect cutting and punching waste. And a guiding plate 52 is fixedly installed in the collection box 51. And a discharge box (refer to Figure 5 is communicatively connected to the side of the collection box 51. The guiding plate 52 is used to guide the waste falling into the collection box 51 to fall into the discharge box. The discharge box has a material taking port 513, and the bottom surface of the inner wall of the discharge box is inclined towards the direction of the material taking port 513;

[0042] Thus, during the cutting and punching operations of the carrying saddle, the waste generated from the waste falling from the feeding plate 515 passes through the guiding part 44 and falls into the collection box 51. When the waste enters the collection box 51, under the guidance of the guiding plate 52, its movement trajectory changes and it slides towards the direction of the discharge box;

[0043] The discharge box is communicatively connected to the collection box 51, and the bottom surface of its inner wall is inclined towards the direction of the material taking port 513. This design enables the waste coming from the collection box 51 through the guiding plate 52 to continue to move towards the material taking port 513 along the inclined bottom surface of the discharge box under the action of gravity. The waste finally converges at the material taking port 513, facilitating the operator to centrally clean and remove it;

[0044] Inside the working chamber 12, the installation component 4 is used to precisely adjust the position of the carrying saddle to cooperate with the cutting and punching operations. The third moving component 42 is installed on the side of the mounting seat 41, and its structure is similar to that of the first moving component to drive the third sliding plate to slide, realizing the preliminary position adjustment and transporting the carrying saddle to the approximate processing area. Then, the fourth moving component 43 further functions on the third sliding plate. Similarly, based on a similar transmission principle, the fourth sliding plate 514 is finely position - adjusted to ensure that the carrying saddle is accurately positioned below the cutting and punching unit.

[0045] When the cutting operation of the carrying saddle is completed, the generated waste needs to be cleaned. At this time, the cut - carrying saddle is still in the clamped state. As the fourth sliding plate 514 moves horizontally, it drives the entire collection component 5 installed on it to move. During the movement, the gear part 58 gradually contacts and then gradually crosses over the top - end first rack 511 on the inner wall of the fixed frame 510. During this process, the meshing of the gear part 58 and the first rack 511 drives the second rotating shaft to rotate, and then through bevel - gear transmission, the first rotating shaft 55 rotates, and the feeding plate 515 rotates 30 degrees along the first rotating shaft 55, presenting an inclined state. At this time, the waste accumulated on the feeding plate 515 automatically dumps under the action of gravity and is guided by the guiding plate 52 to fall into the collection box 51 below.

[0046] As the fourth slide plate 514 continues to move, after the gear part 58 passes over the smooth part on the first rack 511, it begins to contact and pass over the second rack 512 at the bottom end of the inner wall of the fixed frame 510. During this process, the meshing of the gear part 58 with the second rack 512 causes the second rotating shaft to rotate in the reverse direction, and through bevel gear transmission, the first rotating shaft 55 is driven to rotate in the reverse direction again. The material discharging plate 515 rotates in the reverse direction by 30 degrees accordingly and returns to the horizontal state, preparing for the punching work of the bearing saddle next.

[0047] When the punching work is completed, the fourth slide plate 514 resets and moves horizontally. The gear part 58 will indeed contact and gradually pass over the second rack 512 and the first rack 511 on the inner wall of the fixed frame 510 again in sequence. At this time, the gear part 58 first contacts and passes over the second rack 512. At this time, the meshing of the gear part 58 with the second rack 512 drives the second rotating shaft to rotate, and through bevel gear transmission, the first rotating shaft 55 rotates. The material discharging plate 515 rotates 30 degrees along the first rotating shaft 55 and presents an inclined state, so that the punched waste accumulated on the material discharging plate 515 automatically dumps under the action of gravity and falls into the collection box 51 below through the guiding plate 52.

[0048] Then, as the fourth slide plate 514 continues to move, the gear part 58 will pass over the smooth part on the second rack 512, then contact and pass over the first rack 511. During this process, the meshing of the gear part 58 with the first rack 511 causes the second rotating shaft to rotate in the reverse direction, and through bevel gear transmission, the first rotating shaft 55 is driven to rotate in the reverse direction again. The material discharging plate 515 rotates in the reverse direction by 30 degrees accordingly and returns to the horizontal state, preparing for the next processing of the bearing saddle (such as cutting again or other operations).

[0049] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
