Abstract
The utility model provides a lens holder internal diameter adds clamping apparatus, by constituteing in anchor clamps main part (1), anchor clamps sleeve (2), gland (3), anchor clamps main part (1) constitute by exposed core screw thread (1 -1), exposed core (1 -2), sleeve boss (1 -3), bush thread (1 -4), anchor clamps sleeve (2) have sleeve stopping platform (2 -1), sleeve inner wall (2 -2), sleeve outer wall boss (2 -3) to form, insert sleeve boss (1 -3) with the part inner wall earlier, then embolia the part outer wall to sleeve inner wall (2 -2), gland (3) behind the fixed good part, are covered in rotary fixture sleeve (2), then the start -up lathe, carry out internal diameter and chamfer operation to the part. The utility model discloses, owing to be provided with the internal thread on the anchor clamps sleeve, assurance anchor clamps main part can guarantee that the part produces minimum deformation in the course of working along with the rotatory even atress of anchor clamps sleeve to the clamping -force of part.
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of internal diameter clamp for machining for lens bracket.
Background technology
In order to process the surface of the technical requirement that conforms with the regulations, the lathe of clamping workpiece must will realize the positioning and clamping of workpiece before processing, when workpiece is installed, generally first locate rear clamping, and when workpiece is installed on scroll chuck, positioning and clamping carries out simultaneously, workpiece is directly installed on platen or universal fixturing (as three grab chuck, chuck, flat-nose pliers, the standard accessories such as magnechuck) on, sometimes namely centering does not clamp separately, but increasing non-universal product needed for some parts processing and specialized designs manufactures fixture, thus reach rapid and reliably ensure the correct relative position of workpiece to lathe and cutter, and can clamp rapidly, utilize special fixture processing work, processing precision of products can be ensured, can enhance productivity again, but there is no versatility.The design of special fixture, manufacture and maintenance need certain investment, so only in batch production or in producing in enormous quantities, just can obtain reasonable benefit.Lens bracket is high-accuracy parts, needs just can reach processing request to its design special fixtures.
Summary of the invention
The purpose of this utility model is to provide a kind of lens bracket internal diameter clamp for machining, and this fixture is applicable to internal diameter turning and the chamfer machining of camera lens support metallic member.
The technical solution of the utility model is achieved in the following ways: a kind of lens bracket internal diameter clamp for machining, by jig main body, chuck sleeve, gland forms, described jig main body is by bare terminal end screw thread, bare terminal end, sleeve boss, bush whorl forms, described chuck sleeve has sleeve stopping-receding bench, sleeve lining, sleeve outer wall boss forms, described gland is a turning circle cylinder, center is provided with centre bore, it is characterized in that: described jig main body is revolving body multiple stage stage structure, bare terminal end is fixed on lathe three-claw chuck, by bare terminal end threaded adjustment bare terminal end right position.
Described chuck sleeve is revolution hollow structure, and it is outside that sleeve lining is arranged on sleeve boss, and sleeve lining is provided with internal thread, by rolling clamp sleeve, reaches the object of fixed lens support.
Described sleeve outer wall boss is located on sleeve outer wall, and sleeve outer wall boss, in sleeve turning course, keeps camera lens support concentric with turning center.
The utility model, due to chuck sleeve being provided with internal thread, ensure that jig main body can rotate uniform stressed along with chuck sleeve to the chucking power of part, ensure that part produces minimum deformation in process, ensure machining accuracy, reach the object of batch machining part outer surface, saving of work and time.
Accompanying drawing explanation
Fig. 1 is a kind of lens bracket internal diameter of the utility model clamp for machining main body figure.
Fig. 2 is a kind of lens bracket internal diameter of the utility model clamp for machining cover sketch drawing.
Fig. 3 is a kind of lens bracket external diameter of the utility model clamp for machining gland figure.
In figure: 1 jig main body, 1-1 bare terminal end screw thread, 1-2 bare terminal end, 1-3 sleeve boss, 1-4 bush whorl, 2 chuck sleeve, 2-1 sleeve stopping-receding bench, 2-2 sleeve lining, 2-3 sleeve outer wall boss, 3 glands, 3-1 centre bore.
Detailed description of the invention
By Fig. 1, Fig. 2, Fig. 3 knows, lens bracket internal diameter clamp for machining of the present utility model, by jig main body 1, bare terminal end screw thread 1-1, bare terminal end 1-2, sleeve boss 1-3, bush whorl 1-4, chuck sleeve 2, sleeve stopping-receding bench 2-1, sleeve lining 2-2, sleeve outer wall boss 2-3, gland 3, centre bore 3-1 forms, and described jig main body 1 is by bare terminal end screw thread 1-1, bare terminal end 1-2, sleeve boss 1-3, bush whorl 1-4 forms, and described chuck sleeve 2 has sleeve stopping-receding bench 2-1, sleeve lining 2-2, sleeve outer wall boss 2-3 forms, described gland 3 is a turning circle cylinder, center is provided with centre bore 3-1, described jig main body 1 is revolving body multiple stage stage structure, bare terminal end 1-2 is fixed on lathe three-claw chuck, bare terminal end right position is adjusted by bare terminal end screw thread 1-1, described chuck sleeve 2 is revolution hollow structure, it is outside that sleeve lining 2-2 is arranged on sleeve boss 1-3, sleeve lining 2-2 is provided with internal thread, by rolling clamp sleeve 2, reach the object of fixed lens support, described sleeve outer wall is provided with sleeve outer wall boss 2-3, sleeve outer wall boss 2-3 is in sleeve turning course, keep the concentricity of camera lens support and turning center in control range, during use, first part inwall is inserted sleeve boss 1-3, then sleeve lining 2-2 is inserted in part outer wall, rolling clamp sleeve 2, after fixing part, cover gland 3, then lathe is started, internal diameter and chamfering operation are carried out to part, after completing, take off gland 3 successively, chuck sleeve 2, takes off part, completes the internal diameter processing of part, repeats above step, reach the object of batch machining part outer surface.
