Abstract

A support seat processing tool comprises a hole-milling tool and an outer-shape milling tool, wherein the hole-milling tool is formed by that: screw positioning blocks are arranged at the two sides of a support plate and a double-size positioning block is arranged in the middle of the support plate and a clamping block is arranged at the inner side of the screw positioning filling block; the outer-shape milling tool is formed by that: a longitudinal positioning block and a filling block are respectively arranged into the corresponding long round holes at the two sides of the support plate and a horizontal positioning block is perpendicular with a longitudinal positioning block and a pressing block is connected with the upper surface of the filling block. Using the tool design, a component can be processed only by two steps not by complicated multi-step. The support seat processing tool has features of reliable positioning, quick clamping, less change-over time, ensurance of the processing accuracy, greatly increased processing efficiency and reduced work labor intensity.

Description

The supporting seat processing tool

Technical field

The utility model relates to the processing tool design, especially relates to a kind of design of supporting seat processing tool.

Background technology

Along with popularizing of Digit Control Machine Tool, the aluminium alloy processing industry welcome the automated production development golden age, this requirement to technological equipment and functional part thereof is more efficient, precisely.Technological equipment demand to hommization grows with each passing day.On Digit Control Machine Tool, reasonably use the multifunction machine anchor clamps, help guaranteeing machining accuracy, the stabilized product quality of workpiece; Help raising labour productivity and reducing cost; Help improving workman's working condition, guarantee safety in production; Help enlarger bed process scope, realize " a tractor serves several purposes ", enhance productivity.

At present, in the production process of subway car, the processing of smallclothes supporting base has brought a very big difficult problem to production, and this part length has only 100, but need to process slotted hole in the above, bore Φ 8 holes, process the oblique angle, and the most difficult be that the section bar of this part of processing is to be about two meters window pillar section bar, therefore, supporting base needs suitable complicated step in adding, the frock of the first step such as Fig. 1, processing is earlier picked up the ears, and the reprocessing upper surface hole is processed into several segments at last; Second step was adopted the frock as Fig. 2, can only process one at every turn, and efficient is low, when processing capacity is big, was unfavorable for producing in batches.

The utility model content

Technical problem to be solved in the utility model provides a kind of time saving and energy saving double frock, by the design of locating surface and the change of compacted position, reduces manufacturing procedure, reduces centering time and number of changing knife, improves working (machining) efficiency.

For solving the problems of the technologies described above, the utility model provides a kind of supporting seat processing tool, it is characterized in that: comprise the hole milling frock and mill profile frock two parts, the hole milling frock is on the both sides of gripper shoe the screw locating piece to be set, in the middle of the gripper shoe bilateral locating piece is set, screw locating piece inboard is provided with and compresses cushion block; Milling the profile frock is to be respectively equipped with longitudinal register piece and cushion block at the corresponding slotted hole in the both sides of gripper shoe, and the vertical located lateral piece that is provided with the longitudinal register piece connects briquetting above the cushion block.

By the design of this frock, allow the part of multiple working procedure processing of a complexity, being simplified to only needs two to go on foot and just can finish, the location of this frock is reliable, and clamping is quick, and non-cutting time is few, and can either guarantee machining accuracy, and can also improve working (machining) efficiency greatly, reduce labor strength.

Description of drawings

Fig. 1 is known hole milling frock;

Fig. 2 is the known profile frock of milling;

Fig. 3 is the utility model hole milling tool structure schematic diagram;

Fig. 4 is that the utility model mills profile tool structure schematic diagram.

The specific embodiment

With reference to Fig. 1, Fig. 2, first step processing is earlier picked up the ears, and the reprocessing upper surface hole is processed into several segments at last; Second step was milled both sides, can only process one at every turn, and efficient is low, when processing capacity is big, was unfavorable for producing in batches.

With reference to Fig. 3, the 1st, gripper shoe, the gripper shoe both sides are provided with screw locating piece 4, screw locating piece inboard is provided with and compresses cushion block 5, part 3 can be pressed on the frock by screwing screw 6, the 7th, milling cutter is provided with bilateral locating piece 2 in the middle of the gripper shoe, can satisfy the positioning requirements of dual-workpiece, thereby guarantee the positional precision of circular hole.

With reference to Fig. 4, corresponding slotted hole is respectively equipped with longitudinal register piece 13 and cushion block 10 on the both sides of gripper shoe 1, and the vertical located lateral piece 12 that is provided with the longitudinal register piece connects briquetting 8,9th, housing screw, the 11st, a supporting seat that has processed above the cushion block.

When this frock is used, only need be when frock be installed on the workbench of Digit Control Machine Tool centering once, and in the process afterwards, only need to go up workpiece---clamping---processing, improve working (machining) efficiency greatly, more highly embodied the theory of flexible manufacturing system.In the production relatively stable at product, that batch is bigger, adopt this kind special tooling, can obtain higher productivity ratio and machining accuracy, and cost is lower.

Claims

1. supporting seat processing tool is characterized in that: comprise the hole milling frock and mill profile frock two parts, the hole milling frock is on the both sides of gripper shoe the screw locating piece to be set, and in the middle of the gripper shoe bilateral locating piece is set, and screw locating piece inboard is provided with and compresses cushion block; Milling the profile frock is to be respectively equipped with longitudinal register piece and cushion block at the corresponding slotted hole in the both sides of gripper shoe, and the vertical located lateral piece that is provided with the longitudinal register piece connects briquetting above the cushion block.
