A kind of clamp for machining of large complicated cavity class die casting end face
Technical field
The utility model is related to a kind of clamp for machining, the processed clip of specifically a kind of large complicated cavity class die casting end face
Tool, belongs to technical field of processing equipment.
Background technology
Die casting is that quick injection enters in metal mold and solidifies and cast under pressure under high pressure by molten metal
A kind of high-efficiency and precision manufacturing process of part.Lightweight Technology development promotes its crucial die casting device more to tend to enlargement, thin-walled
Change and integration, the application with the large-scale die casting part of complicated cavity structure obtain quick development.For large complicated chamber
It for body class die casting, needs to be processed cavity after Die Casting, the processing quality of end face directly determines part
Assembling quality.During processing, it is necessary first to die casting is fixed, common method is to be designed with technique on die casting to take
Platform is compressed when fixed and is set up the stage, and completes product processing.Then positioning processing is carried out, removal is set up the stage.For above-mentioned operation, in order to complete
Into processing, need two process equipments, it is relatively complicated, and may be resected to when removal technique is set up the stage cavity in itself or
It is still to have remnants by removal processing, it is still necessary to manual polishing.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, facilitates large complicated cavity class die casting end face processing
Fixture.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of clamp for machining of large complicated cavity class die casting end face, including jig platform, on the jig platform
With fixture placement section, in the both lateral sides of the fixture placement section, side is provided with more than one fixing piece, in the fixture
Longitudinal both sides of placement section are provided with more than one fixing piece per side;The fixing piece includes cylinder, connection montant and fixed horizontal stroke
Bar, the cylinder are mounted on jig platform, and the piston rod of the cylinder is connected with connecting montant connection on the connection montant
There is fixed transverse rod.
Specifically, in the both lateral sides of the fixture placement section, per side, there are two fixing pieces for setting, are placed in the fixture
Longitudinal both sides in portion, per side, there are two fixing pieces for setting.
For the ease of processing, the cylinder is mounted on jig platform bottom, and the connection montant passes through jig platform, described
Linear bearing is installed between connection montant and jig platform.
For the ease of placing casting cavity, connected between the connection montant and fixed transverse rod by movable fastener.
For the ease of fixation, the fixed transverse rod head end has fixing lug boss.
In order to be processed to different casting cavitys, the fixed transverse rod length on different fixing pieces is different.
The utility model is simple in structure, one equipment of reduction when being processed for large complicated cavity class die casting end face
It uses, saves equipment usage quantity, also reduce the process manually subsequently polished, improve processing efficiency, reduce production cost.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of clamp for machining of large complicated cavity class die casting end face, including jig platform 1, the folder
Having has fixture placement section on platform 1, for fixture placement section for placing casting cavity 2, casting cavity 2 is placed on fixture placement section
On be processed.
In the both lateral sides of the fixture placement section, be respectively arranged with three (or 2) fixing pieces per side as shown in Figure 1,
In longitudinal both sides of the fixture placement section, two fixing pieces are respectively arranged with per side.The fixing piece includes cylinder 3, connection
Montant 5 and fixed transverse rod 6, the cylinder 3 are mounted on jig platform 1, and the piston rod of the cylinder 3 is connected with connecting montant 5,
Fixed transverse rod 6 is connected on the connection montant 5.It is fixed for the ease of the casting cavity 2 to different structure, difference is fixed
6 length of fixed transverse rod on part is different.Further, the cylinder 3 is mounted on 1 bottom of jig platform, and the connection montant 5 is worn
Jig platform 1 is crossed, linear bearing 4 is installed between the connection montant 5 and jig platform 1.
For the ease of placing and taking out casting cavity 2, fastened between the connection montant 5 and fixed transverse rod 6 by activity
Part 7 connects.Movable fastener 7:When fixing piece works, movable fastener makes to be fixedly connected between connection montant and fixed transverse rod
(in 90 ° or bending chapter state 90 ° approximate), enables fixed transverse rod 6 to clamp and (push down) casting cavity 2;And work as fixing piece not
During work, movable fastener 7 makes to be movably connected between connection montant 5 and fixed transverse rod 6, convenient for casting cavity 2 from fixture
Placement section takes out or places.
Casting cavity 2 is clamped and (pushes down) for the ease of fixed transverse rod 6,6 head end of fixed transverse rod has fixing lug boss 8.
In use, casting cavity 2 is placed on fixture placement section, the fixing piece of both lateral sides does not work, longitudinal both sides
Fixing piece works, and starts processing;It machines and (is partially completed), the fixing piece work of both lateral sides, the fixing piece of longitudinal both sides
It does not work, processes by the fixing piece shield portions of longitudinal both sides, a fixture is just realized the full processing of casting cavity 2, also avoided
Casting cavity 2 is using mode of setting up the stage.
Above-described embodiment does not limit the utility model in any way, every by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the scope of protection of the utility model.
