Abstract
The invention relates to a novel tire expansion clamp comprising a clamp body. The novel tire expansion clamp is characterized in that a pull sleeve capable of moving forwards and backwards, a mandrel fixed on a clamp body, and an expansion sleeve are sequentially installed in the clamp body, wherein the expansion sleeve is connected with the pull sleeve via a pull nail; and a sub expansion sleeve is installed at the outer side of the expansion sleeve, the sub expansion sleeve is clamped in a location disc, and the location disc is fixed on the clamp body. The novel tire expansion clamp disclosed by the invention has the advantages of being reasonable in structure, fast in replacement speed, high in location accuracy and the like, and can realize machining for similar series of components on one clamp, greatly increase the production efficiency and the machining functions of a machine tool, and decreasing the investment of the fixture clamp and production cost, thus bringing economic benefits and social benefits to the manufacturing industry to a certain extent.
Description
Technical field
The present invention relates to a kind of jig, particularly relate to a kind of novel expander fixture.
Background technology
In the mechanical processing process of part, anchor clamps are indispensable parts.Especially a large amount of special fixtures is greatly improved the production efficiency of part, has given full play to the processing characteristics of lathe.But also there is a serious problem in special fixture when bringing into play its superior function, and that is exactly that versatility is poor.
Generally, a machine tool can be processed multiple variety classes, the part of different size, but expander fixture only is suitable for one of them part, and the change of processing parts usually needs to change different anchor clamps, even sometimes also needs redesign to make special fixture.This has not only affected working (machining) efficiency, and so that the processing cost of part improves, the unicity of simultaneously this part processing has restricted the processing characteristics of lathe.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned prior art, provides a kind of raising machine tooling performance and efficient, the expander fixture that cuts down finished cost.
The technical scheme of taking for achieving the above object is:
A kind of novel expander fixture comprises clamp body, it is characterized in that: be equipped with successively in the described clamp body can move forward and backward help pull a cart, be fixed on mandrel and ringfeder on the clamp body, described ringfeder is connected with helping pull a cart by blind rivet; The ringfeder outside is equipped with sub-ringfeder, and this sub-ringfeder is stuck in the positioning disk, and positioning disk is fixed on the clamp body.
Described positioning disk radial and axial on be respectively arranged with to adjust sub-ringfeder position threaded bolt spring nullify.
The endoporus place of described positioning disk is provided with a plurality of breach.
Expander fixture of the present invention has following characteristics: 1. adopt the method for the sub-ringfeder of quick change, can realize at the multiple similar series parts of a cover expander fixture processing; 2. the sub-ringfeder behind the quick change is by the two-way adjustment of threaded bolt spring lock pin, and guaranteeing has higher precision behind its quick change.That the present invention has is rational in infrastructure, replacing speed is fast, the positioning accuracy advantages of higher, can realize the processing of similar series parts on a sleeve clamp, increase substantially production efficiency and the machining functions of lathe, reducing frock clamp drops into, reduce production costs, thereby bring certain economic benefit and social benefit for manufacturing industry.
Description of drawings
Fig. 1 is the structural representation sketch of expander fixture of the present invention;
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structure chart of sub-ringfeder.
The specific embodiment
Expander fixture of the present invention comprises clamp body 1, is disposed with in clamp body 1 and helps pull a cart 2, mandrel 3 and ringfeder 5, helps pull a cart 2 can move forward and backward in clamp body 1, and mandrel 3 is fixed in the clamp body 1, and ringfeder 52 is connected with helping pull a cart by the hole of passing on the mandrel 3.In ringfeder 5 arranged outside sub-ringfeder 9 is arranged, this sub-ringfeder 9 is stuck in the positioning disk 6, and positioning disk 6 is fixed on the clamp body 1.Helping pull a cart 2 is pulled, and hauls ringfeder 5 motions by blind rivet 3, and the relative motion of ringfeder 5 and mandrel 4 makes ringfeder 5 produce strains, and the strain of ringfeder 5 makes sub-ringfeder 9 produce strains, and the tensioner inner hole of workpiece is with clamping work pieces.Endoporus place on positioning disk 6 and the large outer radius of sub-ringfeder 9 are processed three place's breach, can realize the quick-replaceable of sub-ringfeder 9.Positioning disk 6 axially and in the radial direction threaded bolt spring lock pin 7 and 8 are set all, be used for from axially, the footpath adjusts upward the position of sub-ringfeder 9, guarantees to have higher precision behind the quick change.
