Abstract
The utility model provides an elastic pressure head. The elastic pressure head comprises a clamp and pressure lever assemblies arranged on the clamp; as compression springs are mounted at the tops of the pressure levers and rubber gaskets are glued to the bottoms of the pressure levers, the pressure lever assemblies have great elasticity, and the distance of each pressure lever assembly extending out of a chuck can be changed freely along with the profile of a workpiece to be held down, and therefore, the elastic pressure head is capable of holding down various curved-surface parts, easily deformable sheet metal parts and composite material parts, and also capable of effectively preventing parts from being crushed, and thus can be mounted on machine or used for manually holding down parts.
Description
Technical field
The utility model is a kind of compensating squeeze head, belongs to clamping apparatus design field.
Background technology
In field of machining, often need to compress or temporarily fixedly metal plate parts, composite material parts, curved surface part.Instrument can not utilize easily at present, profile feature customization special clamping frock that can only be different according to product.Its shortcoming is: the manufacture of special clamping frock bothers, and the cycle is longer; Cost is higher, is unfavorable for lean production.
Summary of the invention
The utility model just designs a kind of compensating squeeze head is provided for above-mentioned the deficiencies in the prior art, its objective is the part more complicated for fixed profile, rigidity is poor.
The purpose of this utility model is achieved through the following technical solutions:
This kind of compensating squeeze head, it is characterized in that: this compensating squeeze head comprises clamp body (1) and depression bar assembly (2), depression bar assembly (2) comprises spring (4), telescopic shaft (16), shaft block ring (7), rubber blanket (12), clamp body (1) comprises folder axle (14) and chuck (3), circumferencial direction at the chuck (3) of cylindrical shape is evenly distributed with step through-hole (8) around central axis (15), macropore (9) opening of step through-hole (8) is in the lower surface (13) of chuck (3), aperture (5) opening of stepped hole (8) is in the upper surface of chuck (3), top end face at chuck (3) has a columniform folder axle (14), folder axle (14) has a central axis with chuck (3), telescopic shaft (16) is a step axial workpiece that has thick shaft part (11) and thin shaft part (10), thick shaft part (11) bottom face at telescopic shaft (16) is stained with rubber blanket (12), thin shaft part (10) cover at telescopic shaft (16) has Compress Spring (4), pass the macropore (9) of chuck (3) step through-hole (8) and pass from aperture (5), thin shaft part at telescopic shaft (16) goes out to have annular groove (6) near termination, the outer shaft block ring (7) that is provided with of annular groove (6), the synergy of depression bar assembly (2) by shaft block ring (7) and Compress Spring (4) is fixed on the thick shaft part (11) of telescopic shaft (16) and the lower surface (13) of chuck (1) in the step through-hole (8) of chuck (3) and in free situation and has gap.
The utility model has the advantages that depression bar assembly (2) has elasticity, so be applicable to be arranged on lathe or the various yielding sheet metal parts of compression and composite material parts for hand, can effectively prevent from damaging by pressure part, and this utility model can also compress the irregular curved surface part of profile.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device.
The specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further details:
Shown in Figure 1, this kind of compensating squeeze head, it is characterized in that: this compensating squeeze head comprises clamp body 1 and depression bar assembly 2, depression bar assembly 2 comprises spring 4, telescopic shaft 16, shaft block ring 7, rubber blanket 12, clamp body 1 comprises folder axle 14 and chuck 3, circumferencial direction at the chuck 3 of cylindrical shape is evenly distributed with step through-hole 8 around central axis 15, macropore 9 openings of step through-hole 8 are in the lower surface 13 of chuck 3, aperture 5 openings of stepped hole 8 are in the upper surface of chuck 3, top end face at chuck 3 has a columniform folder axle 14, folder axle 14 has a central axis with chuck 3, telescopic shaft 16 is step axial workpieces that have thick shaft part 11 and thin shaft part 10, thick shaft part 11 bottom faces at telescopic shaft 16 are stained with rubber blanket 12, thin shaft part 10 covers at telescopic shaft 16 have Compress Spring 4, pass the macropore 9 of chuck 3 step through-holes 8 and pass from aperture 5, thin shaft part at telescopic shaft 16 goes out to have annular groove 6 near termination, the outer shaft block ring 7 that is provided with of annular groove 6, the synergy of depression bar assembly 2 by shaft block ring 7 and Compress Spring 4 is fixed on the thick shaft part 11 of telescopic shaft 16 in the step through-hole 8 of chuck 3 and in free situation and has gap with the lower surface 13 of chuck 1.
The utility model is attached to the rubber blanket of depression bar assembly 2 12 on the composite that will process, sheet metal part in use, and the pressuring action by spring 9 makes 2 pairs of workpiece of depression bar assembly have certain thrust, and workpiece is fixed.
The utility model compared with prior art, because depression bar top is provided with Compress Spring, bottom is stained with rubber blanket, so depression bar assembly has very large elasticity, the distance that each depression bar assembly stretches out chuck can freely change with the profile for the treatment of workpiece pressing, therefore this utility model can compress various curved surface parts, yielding sheet metal part and composite material parts, and can effectively prevent from damaging by pressure part, is applicable to be arranged on lathe or manual compressing component.
