Description

Technical Field

[0001] This application relates to the field of high-speed rail parts manufacturing and processing technology, specifically to an automated processing device for high-speed rail brake cylinder bodies. Background Technology

[0002] Currently, the basic braking system used in domestic high-speed trains transmits braking force through air compression. The principle involves compressing the air inside the brake cylinder, which generates piston movement. This pressure is then transmitted to the brake lever and brake pad support via a connecting pin, causing the brake pad support to rub against the brake disc. As a crucial component of the braking mechanism, the brake cylinder has specific requirements for its mechanical properties and pressure-bearing capacity.

[0003] Due to the high demand and quality stability requirements of brake cylinder bodies, they are suitable for automated unit production. However, the automated robot arm has positioning errors when installing and placing the workpiece, and the part of the robot arm that holds the workpiece is the main casting surface, which cannot achieve consistent clamping. Therefore, it is necessary to design a clamping fixture to solve the positioning problem in brake cylinder body machining. Utility Model Content

[0004] The purpose of this application is to provide an automated machining device for high-speed rail brake cylinder bodies. By radially positioning the brake cylinder body from the inside and utilizing the structural features of the notch on the upper edge of the brake cylinder body to achieve circumferential positioning, and simultaneously axially pressing the brake cylinder body, the device can avoid clamping the main casting surface of the brake cylinder body, thereby solving the problem of insufficient clamping consistency in existing clamping methods that use robotic arms to clamp workpieces.

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0053] like Figures 1-2 As shown, the brake cylinder body is a cover-shaped structure. The brake cylinder body has two inner bore sections with different diameters. The large-diameter bore section and the small-diameter bore section are connected by a variable-diameter bore section. The edge of the cover of the brake cylinder body has an edge notch 4 to facilitate the fitting of other accessories. The outer side of the brake cylinder body has a cylindrical structure 1.

[0054] Please refer to them together. Figure 3 , Figure 4 and Figure 10 This application provides an automated processing device for high-speed rail brake cylinder bodies. The device includes a base 5, a first positioning mechanism 6, a second positioning mechanism 7, and a clamping mechanism 8. The first positioning mechanism 6 is connected to the base 5 and is used to cooperate with the inner hole of the brake cylinder body to achieve radial positioning of the brake cylinder body. The second positioning mechanism 7 is connected to the base 5 and located on one side of the first positioning mechanism 6. The second positioning mechanism 7 is used to cooperate with the edge notch 4 of the brake cylinder body to achieve circumferential positioning of the brake cylinder body. The clamping mechanism 8 is connected to the base 5 and located on one side of the first positioning mechanism 6. The clamping mechanism 8 is used to abut against the brake cylinder body to achieve axial positioning of the brake cylinder body.

[0055] In use, a robotic gripper can be used to place the brake cylinder body on the base 5. The brake cover completely covers the first positioning mechanism 6. The first positioning mechanism 6 is located inside the small-diameter hole section and contacts / abuts against the hole wall of the small-diameter hole section to achieve radial positioning of the brake cylinder body. At the same time, the second positioning mechanism 7 is located inside the edge notch 4. The second positioning mechanism 7 contacts / abuts against the inner wall of the edge notch 4 to achieve circumferential positioning of the brake cylinder body. The axial positioning of the brake cylinder body can be achieved by axially pressing the brake cylinder body through the clamping mechanism 8. In this way, the brake cylinder body and the base 5 remain relatively fixed, and the brake cylinder body can be further processed.

[0056] The automated machining device for high-speed rail brake cylinders provided in this application embodiment can achieve radial positioning of the brake cylinder from its inner hole through the first positioning mechanism 6, and circumferential positioning of the brake cylinder from its edge notch 4 through the second positioning mechanism 7. Axial positioning of the brake cylinder can be achieved by axially pressing the brake cylinder through the clamping mechanism 8, thereby ensuring the stability of the brake cylinder during the machining process. The side of the brake cylinder, as the main casting surface, does not contact the tooling fixture, avoiding damage to the main casting surface due to clamping. At the same time, repeated clamping is not required when machining the main casting surface, which brings convenience to the machining process.

[0057] In the embodiments of this application, please continue to refer to... Figure 3 The base 5 may specifically include a first mounting base plate 51 and a second mounting base plate 52. The first mounting base plate 51 provides a mounting foundation for the clamping mechanism 8, and the second mounting base plate 52 is attached to and connected to the first mounting base plate 51. The second mounting base plate 52 provides a mounting foundation for the first positioning mechanism 6 and the second positioning mechanism 7.

[0058] In some alternative embodiments, see further. Figure 3 The base 5 is provided with a positioning boss 53, which is configured as a hollow structure. The positioning boss 53 is provided with an installation groove suitable for accommodating the structure of the first positioning mechanism 6.

[0059] In this embodiment, the design of the positioning boss 53 can provide a higher installation position for the first positioning mechanism 6. After the mounting groove on the positioning boss 53 cooperates with part of the structure of the first positioning mechanism 6, it can provide a certain radial support force for the first positioning mechanism 6, thereby reducing the bearing pressure of the first positioning mechanism 6 during the processing, and thus ensuring the posture accuracy of the brake cylinder body during the processing.

[0060] The first positioning mechanism 6 can be engaged with the small-diameter bore section in the brake cylinder body through an adsorption method, for example, by equipping the first positioning mechanism 6 with multiple adsorption heads that simultaneously adsorb onto the bore wall of the small-diameter bore section; or it can be engaged through a pressing method, for example, by designing multiple pressing heads that simultaneously press against the inner wall of the small-diameter bore section. Compared to the adsorption method, the pressing method has relatively lower requirements for the positional accuracy of the brake cylinder body and provides a centering function. Therefore, in some optional embodiments, the first positioning mechanism 6 adopts a pressing method to engage with the small-diameter bore section of the brake cylinder body. (See reference...) Figure 3 The first positioning mechanism 6 may specifically include a retainer 61, positioning posts 62, and a first drive mechanism 63. The retainer 61 is located in the mounting groove and connected to the positioning boss 53. In actual implementation, the mounting groove on the positioning boss 53 can be designed as a circular groove, and the overall shape of the retainer 61 is designed as a cylinder. The height of the retainer 61 is greater than the depth of the mounting groove, so that part of the structure of the retainer 61 is located outside the mounting groove in the axial direction. The number of positioning posts 62 is configured to be at least two and evenly distributed around the axial direction of the positioning boss 53. The positioning posts 62 are used to abut against the inner wall of the small-diameter hole section. The shape of the positioning posts 62 is... The positioning post 62 can be designed to be circular, thus having a smaller contact area between it and the inner wall of the small-diameter bore section. Simultaneously, the smooth outer wall of the positioning post 62 can prevent damage to the inner wall of the small-diameter bore section. The positioning post 62 is elastically slidably connected to the retainer 61 to move elastically in the radial direction of the positioning boss 53. The first drive mechanism 63 is driven by the positioning post 62 to move elastically in the radial direction of the positioning boss 53. Since the positioning post 62 and the retainer 61 are elastically slidably connected, the positioning post 62 can return to its original position automatically after the driving force of the first drive mechanism 63 on the positioning post 62 is removed. Typically, to make the clamping force of the positioning post 62 on the brake cylinder controllable, the first drive mechanism 63 drives the positioning post 62 to move away from the axis of the retainer 61.

[0061] The first drive mechanism 63 can be designed as one or more. When there is only one first drive mechanism 63, it can be connected to each positioning post 62 through an intermediate transmission structure. When there are multiple first drive mechanisms 63, each first drive mechanism 63 can drive the positioning post 62 to move. In order to ensure the synchronization of the movement of each positioning post 62 and reduce manufacturing costs, some optional embodiments can be referred to Figure 4 and Figure 5The first drive mechanism 63 includes a drive wedge 631, a drive column 632, and a first drive assembly 633. The drive wedge 631 is located in the mounting groove and is slidably connected to the positioning boss 53 to move radially in the positioning boss 53. The drive wedge 631 and the bottom of the mounting groove can be slidably connected by a slider-slide structure. The drive wedge 631 is also located inside the retainer 61, and the retainer 61 and the bottom of the mounting groove form a relatively sealed space, which can provide a certain degree of protection for the drive wedge 631. Multiple drive wedges 631 are evenly distributed around the axial direction of the positioning boss 53 and correspond one-to-one with the position of the positioning column 62. The drive wedge 631 and the positioning column 62 are driven together, so that when the drive wedge 631 moves, it can drive the positioning column 62 to move synchronously. The drive column 632 has a drive wedge surface suitable for cooperating with the drive wedge 631. Multiple independent driving wedge surfaces can be machined on the outer wall of the drive column 632, i.e., the overall shape of the drive column 632 is a frustum, and each driving wedge surface cooperates with the drive wedge block 631. Alternatively, the entire outer wall of the drive column 632 can be machined into a single driving wedge surface, i.e., the overall shape of the drive column 632 is a frustum. The driving wedge surface can face either the bottom of the mounting groove or the opening of the mounting groove. The first drive assembly 633 is connected to the base 5. The first drive assembly 633 can be located inside the positioning boss 53. The moving end of the first drive assembly 633 passes through the positioning boss 53 from the inside of the positioning boss 53 so that the moving end is located in the mounting groove. The moving end of the first drive assembly 633 is connected to the drive column 632 to drive the drive column 632 to move along the axial direction of the positioning boss 53, thereby forming different contact areas between the driving wedge surface and the drive wedge block 631.

[0062] In this embodiment, the combination of the drive wedge 631 and the drive column 632 enables stepless adjustment of the positioning radius of the positioning column 62, thereby making the holding force of the positioning column 62 on the brake cylinder more controllable and providing higher adjustment accuracy.

[0063] In some optional embodiments, the shape of the drive column 632 is preferably designed as a frustum, that is, the drive column 632 is designed with multiple drive wedge surfaces to cooperate with the drive wedge block 631 respectively. The drive wedge block 631 is provided with a groove adapted to the shape of the drive column 632, thereby providing precise motion guidance for the drive column 632 and ensuring the relative motion accuracy of the drive wedge block 631 and the drive column 632.

[0064] In some optional embodiments, in order to increase the active radius of the positioning post 62 and control the size of the retainer 61, the positioning post 62 can be elastically slidably connected to the retainer 61 through an intermediate transmission member 64. Specifically, the overall shape of the intermediate transmission member 64 is generally Z-shaped, with one end located in the mounting groove and the other end located outside the mounting groove and outside the retainer 61. The intermediate transmission member 64 and the retainer 61 can be slidably connected by a slider-slide groove structure, and a helical spring is provided in the slide groove to achieve elastic reset of the positioning post 62. The end of the intermediate transmission member 64 located in the mounting groove is connected to the drive wedge block 631.

[0065] In some alternative embodiments, such as Figure 6 As shown, the first drive assembly 633 includes a drive cylinder 6331, a connecting shaft 6332, and a protective sleeve 6333. The drive cylinder 6331 is connected to the base 5 and is located inside the positioning boss 53. One end of the connecting shaft 6332 is threadedly connected to the moving end of the drive cylinder 6331, and the other end passes through the positioning boss 53 and the drive column 632 in sequence. A limiting shoulder is provided on the connecting shaft 6332 to axially limit the drive column 632. The protective sleeve 6333 is sleeved on the connecting shaft 6332 from the other end of the connecting shaft 6332. A locking nut is also threaded on the connecting shaft 6332 to press the protective sleeve 6333 against the drive column 632. By driving the drive cylinder 6331 to move the drive column 632, the overlapping area of ​​the drive wedge surface and the drive wedge block 631 can be changed, so that the drive wedge block 631 can slide in the mounting groove. In turn, the drive wedge block 631 can drive the intermediate transmission component 64 of the positioning column 62 to move, thereby causing the positioning column 62 to move radially.

[0066] In some optional embodiments, see also Figure 7 and Figure 8 The second positioning mechanism 7 includes a positioning element 71 and a second driving mechanism. The positioning element 71 has a first positioning end and a second positioning end. The second driving mechanism is connected to the base 5 and to the positioning element 71 to drive the positioning element 71 to rotate. When the positioning element 71 rotates to a predetermined position, the first positioning end and the second positioning end can respectively connect with the inner wall of the edge notch 4, which means that the positioning element 71 can respectively limit the brake cylinder in the clockwise or counterclockwise direction. When the positioning element 71 leaves the predetermined position, the first positioning end and the second positioning end respectively disengage from the inner wall of the edge notch 4. At this time, when the brake cylinder is removed, the brake cylinder will not rub against the positioning element 71.

[0067] In this embodiment, the structural features of the notch 4 on the edge of the brake cylinder are fully utilized. By placing the positioning member 71 inside the notch 4 and having the first and second positioning ends contact the inner wall of the notch 4, the circumferential positioning of the brake cylinder can be achieved. There is no need to design a clamping mechanism, and the main casting surface on the outer side of the brake cylinder will not be damaged. At the same time, the rotatable feature of the positioning member 71 ensures that the brake cylinder will not rub against the positioning member 71 when it is removed, making the implementation more convenient.

[0068] In some alternative embodiments, both the first positioning end and the second positioning end are constructed as arc-shaped protrusions.

[0069] In this embodiment, the arc-shaped protrusion has a smooth side surface. When the positioning member 71 rotates to or away from the predetermined position, the contact area between the positioning member 71 and the inner wall of the edge notch 4 is smaller, which can reduce mutual wear during the positioning process.

[0070] In some alternative embodiments, the positioning element 71 is an elliptical sheet structure for ease of manufacture.

[0071] In some alternative embodiments, the second drive mechanism is configured as a rotary cylinder.

[0072] In this embodiment, the main station of the positioning component 71 is to rotate the positioning component 71 to a predetermined position. Therefore, the positioning requirement of the positioning component 71 is small, and the angle of the positioning component 71 can be controlled by a rotary cylinder. Compared with the motor usually used, the implementation cost is relatively low.

[0073] In some alternative embodiments, such as Figure 9 As shown, the clamping mechanism 8 includes a telescopic drive source 81 and a clamping block 82; the telescopic drive source 81 is connected to the base 5; the clamping block 82 is connected to the telescopic drive source 81 to move in a direction parallel to the axial direction of the positioning boss 53 under the drive of the telescopic drive source 81; wherein, the clamping block 82 is constructed with an arc-shaped notch adapted to the cylindrical structure 1 on the brake cylinder body; that is, when the clamping block 82 clamps the brake cylinder body, the cylindrical structure 1 can be located in the arc-shaped notch, so that the arc-shaped notch can play a role in circumferential auxiliary positioning, which, together with the positioning function of the positioning member 71, makes the brake cylinder body have more precise positional accuracy in the circumferential direction. At the same time, if the second positioning mechanism 7 malfunctions, the limit of the cylindrical structure 1 by the arc-shaped notch also serves as a backup positioning structure.
