Description

Technical Field

[0001] This utility model relates to the field of coupler component processing technology, and in particular to positioning fixtures for coupler component processing. Background Technology

[0002] Couplers are key connecting components of rail vehicles, and their machining accuracy directly affects driving safety. Currently, coupler components are mostly clamped using mechanical clamping plates or universal fixtures. Most existing clamping methods rely on bolt tightening, which is inefficient, requires manual adjustment of bolt tightness, and is cumbersome. Furthermore, the complex structure of coupler components makes them difficult to clamp effectively with universal fixtures, easily leading to vibrations during machining and thus affecting processing. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for the processing of coupler components.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A positioning fixture for machining coupler components includes a base. A clamping mechanism is symmetrically arranged in the center of the upper surface of the base. A tail-end limiting mechanism and a top-end limiting mechanism are respectively arranged on both sides of the clamping mechanism on the upper surface of the base. The clamping mechanism includes a first electric cylinder frame mounted on the base. A first servo electric cylinder is vertically mounted on the first electric cylinder frame. A rotating connecting seat is arranged on the upper surface of the first electric cylinder frame. A connecting rod is rotatably connected to the rotating connecting seat via a rotating connecting plate. One end of the connecting rod is rotatably connected to a rotating connecting head, and the bottom of the other end is fitted with an upper clamping block. A lower clamping mechanism is arranged below the upper clamping block on the upper surface of the base. A coupler is clamped between the upper clamping block and the lower clamping mechanism.

[0006] In addition, a preferred structure is that the bottom of the upper clamping block is provided with an upper clamping groove, which is used to cooperate with the lower clamping mechanism to clamp the car coupler.

[0007] Furthermore, in a preferred configuration, a first piston rod is mounted and connected to the top output end of the first servo electric cylinder, and the first piston rod is used for mounting and connecting with a rotating connector.

[0008] Furthermore, in a preferred configuration, the tail end limiting mechanism includes a mounting bracket, which is disposed on the upper surface of the base. A rubber block is disposed on the side of the mounting bracket facing the top limiting mechanism, and the rubber block is used to abut against the vehicle coupler.

[0009] Furthermore, in a preferred configuration, the top limiting mechanism includes a second electric cylinder frame, on which a second servo electric cylinder is horizontally mounted, and a tail-end limiting mechanism with the output end of the second servo electric cylinder facing one side. A second piston rod is assembled and connected to the output end of the second servo electric cylinder, and a limiting block is assembled at the end of the second piston rod.

[0010] In addition, a preferred structure is that the lower clamping mechanism includes a support base, a lower clamping block is provided on the top of the support base, and a lower clamping groove is provided on the upper surface of the lower clamping block. The lower clamping groove is used to cooperate with the upper clamping groove to clamp the car coupler.

[0011] The beneficial effects of this utility model are as follows: This utility model achieves efficient linkage clamping through the upper clamping mechanism and the lower clamping mechanism. The clamping mechanism adopts the first servo electric cylinder to drive the connecting rod, and controls the lifting and lowering of the upper clamping block through the piston rod to achieve one-button quick opening and closing, effectively reducing manual operation time. The rubber block of the tail limit mechanism buffers the axial impact, and the servo electric cylinder of the top limit mechanism pushes the limit block to rigidly lock, thus offsetting the processing vibration force in both directions and preventing the workpiece from moving. This positioning fixture can effectively clamp the coupler parts. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-6 A positioning fixture for processing car coupler parts includes a base 1. An upper clamping mechanism 3 is symmetrically arranged in the middle of the upper surface of the base 1. A tail end limiting mechanism 2 and a top end limiting mechanism 5 are respectively arranged on both sides of the upper clamping mechanism 3 on the upper surface of the base 1. The upper clamping mechanism 3 includes a first electric cylinder frame 31 installed on the base 1. A first servo electric cylinder 32 is vertically arranged on the first electric cylinder frame 31. A rotating connecting seat 37 is arranged on the upper surface of the first electric cylinder frame 31. A connecting rod 35 is rotatably connected to the rotating connecting seat 37 through a rotating connecting plate 36. A rotating connecting head 34 is rotatably connected to one end of the connecting rod 35, and an upper clamping block 38 is installed at the bottom of the other end. A lower clamping mechanism 6 is arranged on the upper surface of the base 1 below the upper clamping block 38. A car coupler 4 is clamped between the upper clamping block 38 and the lower clamping mechanism 6.

[0021] The upper clamping block 38 has an upper clamping groove 381 at its bottom. The upper clamping groove 381 is used to cooperate with the lower clamping mechanism 6 to clamp the car coupler 4. The upper clamping groove 381 is used to hold the car coupler 4.

[0022] In addition, a first piston rod 33 is assembled and connected to the top output end of the first servo electric cylinder 32. The first piston rod 33 is used to assemble and connect with the rotating connector 34 and to lift the connecting rod 35.

[0023] Furthermore, the tail end limiting mechanism 2 includes a mounting bracket 21, which is located on the upper surface of the base 1. A rubber block 22 is provided on the side of the mounting bracket 21 facing the top limiting mechanism 5. The rubber block 22 is used to hold the coupler 4. The top limiting mechanism 5 includes a second electric cylinder frame 51, on which a second servo electric cylinder 52 is horizontally mounted. The output end of the second servo electric cylinder 52 faces the tail end limiting mechanism 2. A second piston rod 53 is assembled and connected to the output end of the second servo electric cylinder 52. A limiting block 54 is assembled at the end of the second piston rod 53. The limiting block 54 is used to hold the coupler 4.

[0024] Meanwhile, the lower clamping mechanism 6 includes a support base 61, a lower clamping block 62 is provided on the top of the support base 61, and a lower clamping groove 621 is provided on the upper surface of the lower clamping block 62. The lower clamping groove 621 is used to cooperate with the upper clamping groove 381 to clamp the car coupler 4.

[0025] In this embodiment, when processing the coupler 4, it can be clamped using this tooling. The first servo cylinder 32 retracts its first piston rod 33, and the second servo cylinder 53 retracts its second piston rod 53. The first piston rod 33 cooperates with the rotating connector 34 to make the connecting rod 35 rotate on the rotating connecting plate 36, and the upper clamping block 38 is raised, so that the coupler 4 can be placed on the lower clamping groove 621. The first piston rod 33 is raised, so that the upper clamping block 38 is pressed on top, and the coupler 4 is clamped by the upper clamping block 38 and the lower clamping block 62.

[0026] At the same time, the second servo electric cylinder 52 on the other side drives the second piston rod 53 to extend, so that the limiting block 54 locks the coupler 4. The limiting block 54, together with the rubber block 22, abuts against both ends of the coupler 4, thereby preventing the coupler 4 from shaking and facilitating processing.

[0027] In this utility model, the upper clamping mechanism 3 and the lower clamping mechanism 6 work together to achieve efficient linkage clamping. The clamping mechanism 3 uses the first servo electric cylinder 32 to drive the connecting rod 35, and the piston rod 33 controls the lifting and lowering of the upper clamping block 38 to achieve one-button quick opening and closing, effectively reducing manual operation time. The rubber block 22 of the tail limit mechanism 2 buffers the axial impact, and the servo electric cylinder 52 of the top limit mechanism 5 pushes the limit block 54 to rigidly lock, thus bidirectionally offsetting the processing vibration force and preventing the workpiece from moving. This positioning fixture can effectively clamp the coupler parts.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
