Abstract
A precise milling clamp for a brake beam strut groove. The main problem of current pillar groove finish milling adds clamping utensil need a lot of clamping and cause the error great, production efficiency is low of solving. The method is characterized in that: the hydraulic rotary table is characterized in that a hydraulic rotary table (2) is connected to the upper portion of the base plate (1), a clamping tool (4) is fixed on the hydraulic rotary table (2), a hydraulic rotary joint (7) is connected to the base plate (1) through an upright column, and a hydraulic chuck (3) is connected to the bottom of the hydraulic rotary joint (7). The finish milling machining can be completed by the aid of the finish milling clamp for the brake beam strut groove through one-time clamping, auxiliary time for multiple clamping and positioning is shortened, clamping precision is improved, and production efficiency is improved.
Description
Technical Field
The utility model relates to the field of machinary, specific smart milling fixture in braking beam pillar groove that says so.
Background
The brake beam is an important part in a basic brake system of the railway wagon, and plays a significant role in guaranteeing the running safety of the wagon. The brake beam strut is a key part in the brake beam, the quality condition of the brake beam strut directly influences the performance of the basic brake device of the vehicle, and along with the development of the railway transportation department, higher requirements are provided for the processing quality and the processing efficiency of the brake beam strut. The milling of the central groove of the brake beam strut is a key process in the machining process, the cutting amount of the process is large, the precision requirement is high, the technical requirement on operators is high, and the quality problem is easy to occur, so that the efficient and stable clamp is a key factor for determining the quality and the efficiency of the process.
At present, flat tongs are adopted for positioning and clamping during pillar groove fine machining, and because workpieces are castings, the size difference between the workpieces is large, so that the positioning precision of a positioning block is not high, and the machining size precision is directly influenced. The common vertical milling machine adopts manual feeding for milling, which easily causes the quality problems of low processing size precision, uneven processing surface smoothness and the like. The flat tongs are manually operated to clamp and loosen, and a workpiece needs to be repeatedly clamped for a plurality of times during processing, so that the labor intensity of workers is high, and the production efficiency is low.
Disclosure of Invention
Need a lot of clamping and cause the error great, production efficiency low not enough in order to overcome current post groove finish milling anchor clamps, the utility model provides a brake beam post groove finish milling anchor clamps, this brake beam post groove finish milling anchor clamps clamping can accomplish the finish milling and process, has reduced the assistance-time of a lot of clamping location, has improved the clamping precision, improves production efficiency.
The technical scheme of the utility model is that: the utility model provides a smart milling fixture of brake beam pillar groove, includes the bottom plate, bottom plate upper portion is connected with hydraulic swivel work head, is fixed with on the hydraulic swivel work head and presss from both sides tight frock, be connected with hydraulic swivel joint through the stand on the bottom plate, hydraulic swivel joint bottom is connected with the hydraulic chuck.
And a positioning shaft is fixed at the center of the clamping tool, and elastic positioning blocks are arranged on two sides of the positioning shaft.
The milling cutter is in the horizontal direction, is positioned above one side of the clamping tool and is aligned with the workpiece.
The utility model discloses following beneficial effect has: by adopting the scheme, the whole processing procedure is completed by clamping once by adopting special numerical control processing equipment, a hydraulic rotary worktable and a special clamp. The tool is accurate in positioning and reliable in clamping, the processing quality and the production efficiency are effectively improved, the processing cost and the labor intensity of workers are reduced, the processing reliability and the safety are greatly improved, the processed workpiece completely meets the technical requirements of drawings, and the production efficiency is higher; the tool has the advantages of low manufacturing cost, durability, and convenience for maintenance, and is approved by operators and inspectors.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figures 1 and 2, the brake beam strut groove fine milling fixture comprises a base plate 1, wherein the base plate 1 is fixed on a numerical control horizontal milling workbench, the upper portion of the base plate 1 is connected with a hydraulic rotary workbench 2, and the hydraulic rotary workbench 2 is two stations and rotates 180 degrees at each time. A clamping tool 4 is fixed on the hydraulic rotary workbench 2, a positioning shaft 5 is fixed at the center of the clamping tool 4, elastic positioning blocks 6 are arranged on two sides of the positioning shaft 5, the positioning shaft 5 can be positioned after being inserted into a center hole of a workpiece, and the workpiece is clamped through the elastic positioning blocks 6 on two sides. The hydraulic rotary table is characterized in that a stand column is fixed on one side of the upper portion of the bottom plate 1, the top end of the stand column is connected with a hydraulic rotary joint 7 through a cross beam, the bottom of the hydraulic rotary joint 7 is connected with a hydraulic chuck 3, and the hydraulic rotary joint 7 can rotate 180 degrees and is matched with the hydraulic rotary table 2. The hydraulic chuck 3 can move up and down under the drive of the hydraulic cylinder to clamp a workpiece, and the clamping force is adjustable, so that the vibration caused by insufficient clamping force can be stably and reliably prevented in workpiece processing. Still include milling cutter 8, milling cutter 8 is the horizontal direction, is located the top of pressing from both sides tight frock 4 one side and aligns with the work piece, carries out the milling flutes to the work piece.
When the brake beam strut is milled with a groove, the clamp is fixed on a workbench of a horizontal numerical control milling machine, a workpiece is placed into the clamp, a central hole of the strut is matched with a clamping and positioning shaft 5, and the lower part of the strut is contacted with elastic positioning blocks 6 on two sides; starting a hydraulic cylinder to drive a hydraulic chuck 3 to move downwards to clamp a workpiece, wherein a central hole of a strut is in contact positioning with a positioning shaft 5, two sides of the strut are in contact positioning with an elastic positioning block 6, and the hydraulic cylinder drives the hydraulic chuck to clamp the workpiece; starting a numerical control horizontal milling automatic strut finish milling groove program, and processing a through notch and a stepped groove on one side to reach the size of the drawing; the hydraulic rotary worktable 2 drives the clamp and the workpiece to integrally rotate 180 degrees for positioning and clamping; the milling cutter 8 processes the through notch and the stepped groove on the other side to reach the size of the drawing; and operating the hydraulic rotary worktable 2 to rotate to the original position, loosening the clamping oil cylinder, unloading the workpiece, re-clamping the workpiece, and starting the next cycle process.
