Abstract
The utility model belongs to aeronautical structure spare numerical control processing field discloses an aeroengine adds number and mills side top wedge slide jig, including anchor clamps wedge seat, wedge tooth top slider, screw rod, nut. The wedge-shaped seat props against the side face of the blank, and the wedge-shaped seat is fixed on the milling machine platform by using a screw and a nut. The wedge-shaped tooth top sliding block is arranged in the wedge-shaped seat groove. The tooth end of the wedge-shaped tooth top sliding block is propped against the surface of the wool. And the wedge-shaped tooth top sliding block is fixed on the platform and the wedge-shaped seat by using a screw and a nut. The clamp can greatly reduce the blank allowance of the traditional numerical control machining, and eliminate a large amount of blank waste caused by a clamping mode. The clamp can generate extrusion and friction force on the side surface of the wool simultaneously. The clamp has the advantages that extrusion forces in two directions are generated, the wool is pressed to the surface of the machine bed when the extrusion is supported, only two components are needed for main parts of the clamp, a universal screw and a nut are used for clamping, the structure is simple, the use is convenient, and the manufacturing cost is low.
Description
Technical Field
The utility model belongs to aeronautical structure spare numerical control processing field, concretely relates to aeroengine adds number and mills side top wedge slide jig.
Background
At present, the aeronautical manufacturing trade uses overall structure machine to add a piece as the owner, and part quantity is big, and part size is big, and current machine tooling part clamping is when mostly general clamp plate restriction vertical direction degree of freedom, and the indirect frictional force that utilizes restricts the horizontal direction degree of freedom, because when restricting the vertical direction degree of freedom, the top surface edge of the blank will be pushed down to anchor clamps, pushes down the region and adds the cutter cutting and dodges the reason, and the blank just needs the surplus to be big a lot than part overall dimension, causes the blank size big.
When the top pressing plate is clamped, the limiting force in the horizontal direction is only friction force, the limiting force is slightly insufficient, and if lateral clamping is increased, the clamping complexity is increased, and repeated clamping is realized. In addition, the number of limiting positions is large, machining avoidance is complex, programming and machining time is prolonged, and the defects exist in the actual production application.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses can reduce the woollen size, increase level and vertical direction's confining force, effectively reduce the complexity of woollen cost and sword way programming, it is extravagant to reduce when raising the efficiency, reduces manufacturing cost.
In order to realize the purpose, the technical scheme is as follows:
an aeroengine machining numerical-milling side top wedge sliding clamp comprises a wedge-shaped seat, a wedge-shaped tooth top sliding block, a screw rod and a nut; the wedge-shaped seat is provided with a threaded hole and a screw pressure groove and is fixed on the milling machine platform through a screw and a nut; the wedge-shaped seat props against the side surface of the wool; the wedge-shaped tooth top sliding block is arranged on the wedge-shaped seat, and the wedge-shaped seat is provided with a wedge-shaped matching surface which is matched with the wedge-shaped tooth top sliding block; the wedge-shaped tooth top sliding block and the wedge-shaped seat penetrate through the threaded hole and are fixed on a milling machine platform through a screw and a nut; the wedge-shaped tooth top sliding block is provided with a tooth-shaped top head which is used for propping against the side surface of the wool.
Preferably, the wedge-shaped tooth top slide block is arranged in the groove of the wedge-shaped matching surface of the wedge-shaped seat.
Preferably, the tooth-shaped top head of the wedge-shaped tooth top sliding block is larger than the top surface of the wedge-shaped seat, so that the wedge-shaped tooth top sliding block is embedded and matched to form the separation in the horizontal direction and the vertical direction.
Preferably, the wedge-shaped mating surface is angled at 20 ° to the horizontal.
The utility model discloses an aircraft adds number and mills side top wedge slide jig optimizes the numerical control and adds the anchor clamps mode, reduces the coarse fodder size surplus of the mode of original centre gripping, reduces the coarse fodder cost, eliminates extravagantly. Meanwhile, the restriction force in the horizontal direction and the vertical direction is increased, the restriction force and the stability are increased, the wool cost and the complexity of cutter path programming are effectively reduced, the efficiency is improved, the waste is reduced, and the manufacturing cost is reduced.

Detailed Description
The following is a detailed description of the present invention, but is not intended to limit the invention in any way.
Example 1
A wedge sliding clamp for a side top of an aircraft machining numerical milling machine comprises a wedge seat 1, a wedge tooth top sliding block 2, a screw rod 3 and a nut 4, as shown in figures 1-3. The wedge-shaped seat 1 tightly pushes the wool, is connected to a processing platform by a screw rod 3 and is screwed by a matched nut 4; placing the wedge-shaped tooth top sliding block 2 in a wedge-shaped groove of the wedge-shaped seat 1, connecting the wedge-shaped tooth top sliding block to a processing platform by using an M14 screw rod 3, and screwing the wedge-shaped tooth top sliding block by using a matched nut 4;
the size of the wedge-shaped seat 1 is 150x50x40mm, the height of the top surface and the screw rod connecting surface is 15mm, the included angle between the wedge-shaped surface and the horizontal plane is 20 degrees, and the wedge-shaped surface is a groove with the height of 1 mm.
Wedge tooth top slider 2, wedge face size and 1 recess of wedge seat cooperate, pinion rack thickness is 15mm, 5 teeth, single tooth top 0.3 ~ 0.5mm.
The wedge-shaped seat 1 and the wedge-shaped tooth top sliding block 2 are made of 45# cast steel, and the hardness is more than 35 HRC.
The screw 3 is a standard screw with the specification of M12-M16, and the nut 4 is matched with the screw.
The wedge-shaped seat 1, the wedge-shaped tooth top slide block 2, the threaded hole and the screw groove are matched with the screw, and the length of the wedge-shaped seat meets the size requirement of the wool.
The wedge-shaped tooth top sliding block is fixed on the platform and the wedge-shaped seat by using the screw and the nut, so that the freedom degrees in the horizontal direction and the vertical direction are limited, and meanwhile, the clamp and the clamping mode are simplified to the greatest extent.
