Abstract
The utility model discloses the effective adjustable fixed length of a kind of car cover top, it comprises top matrix (1), adjusting screw (3), and main shaft tie-plate (5), is characterized in that: the afterbody of described top matrix (1) is connected with adjusting screw (3) one end; The center screw of adjusting screw (3) other end screw rod shaft and main shaft tie-plate 5 is threaded connection, and the end of this end adjusting screw (3) is provided with square head, and main shaft tie-plate (5) is connected with lathe spindle (7).The utility model, by regulating adjusting screw, causes the top change to scroll chuck outer face distance, so that can be used for the processing of different casing length.Need not need change top because of the length change of sleeve pipe, achieve characteristic general within the specific limits.
Description
Technical field
The utility model belongs to machining equipment field, and the effective adjustable fixed length of car cover relating to the use of a kind of lathe is top.
Background technology
Lathe uses widely in manufacturing industry, and turning casing length is one common operation, when processing cover pipe part, general method is that sleeve pipe one end endoporus is close to stationary center, with scroll chuck gripping sleeve cylindrical, but because the sleeve pipe model of processing is various, length is inconsistent, the even difference about 110mm had, so that often there is following problem in process of production: when after the stationary center for short sleeve design con-trol length, and switch and to there will be sleeve pipe when adding section chief's sleeve pipe to expose the length of claw longer, rocking appears in process middle sleeve, size is difficult to control and there is the potential safety hazard that part flies out, after controlling the stationary center of length for length sleeve design, and there will be the size that need process in claw when switching processing short sleeve, cannot process.Because of the diversity of product type, although it is also infeasible because size differs greatly to control length that its intermediate sizes is got in consideration design, usually need to change different stationary centers, and stationary center is fixed to chuck end face distance due to it, usability is narrow, and causing needs frequent stationary center of changing to be suitable for the product of different model.
Utility model content
The purpose of this utility model, is to provide a kind of effective adjustable fixed length of car cover in lathe use top, reduces stationary center as far as possible and change the frequency.
The technical solution of the utility model:
The effective adjustable fixed length of a kind of car cover is top, and it comprises top matrix, adjusting screw, main shaft tie-plate, and the afterbody of described top matrix is connected with adjusting screw one end; The center screw of adjusting screw other end screw rod shaft and main shaft tie-plate is threaded connection, and the end of this end adjusting screw is provided with square head, and main shaft tie-plate is connected with lathe spindle.
Described main shaft tie-plate is provided with positioning spigot and through hole, and main shaft tie-plate is located by connecting by positioning spigot and lathe spindle, is fixedly connected with the endoporus of lathe spindle by through hole and fastening bolt.
Described top matrix afterbody is provided with screw, the center of this screw and the central coaxial of top matrix, and adjusting screw and top matrix afterbody screw are threaded connection, and junction is provided with top stop nut.
The center screw threaded connection place of adjusting screw screw rod shaft and main shaft tie-plate is provided with shaft stop nut, and in the middle of adjusting screw, polished rod position is provided with two parallel planes.
The utility model by main shaft tie-plate by bolt-connection on main shaft, top matrix and adjusting screw are threaded connection fixing, spindle coupling disc is threaded connection, and the screw thread that adjusting screw one section is long, due to by regulate adjusting screw, cause top matrix to the change of claw outer face distance, therefore can be used for the processing of casing length change.Need not need change top because of the length change of sleeve pipe, achieve characteristic general within the specific limits.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: top matrix 1, top stop nut 2, adjusting screw 3, fastening bolt 4, main shaft tie-plate 5, shaft stop nut 6, lathe spindle 7.
Detailed description of the invention
The utility model specifically can be implemented according to the technology in technical scheme, further illustrates embodiment with following nonlimiting examples.
Embodiment: as shown in Figure 1, the effective adjustable fixed length of a kind of car cover is top, it comprises top matrix 1, the afterbody of described top matrix 1 is cylinder, head is cone, a screw is provided with at tail end face, described screw and top matrix 1 central coaxial, adjusting screw 3 and top matrix 1 are threaded connection, top stop nut 2 is threaded connection with adjusting screw 3, adjusting screw 3 and main shaft tie-plate 5 are threaded connection, described main shaft tie-plate 5 end face is provided with through hole, be connected with lathe spindle 7 by fastening bolt 4, shaft stop nut 6 and adjusting screw 3 are threaded connection, one end of described adjusting screw 3 is provided with square head.
Adjusting screw 3 middle polished rod position is provided with two parallel planes.
Main shaft tie-plate 5 is provided with and the positioning spigot of lathe spindle 7 inner hole and four uniform through holes.
Adjustable fixed length is top, and associated with lathe spindle 7 afterbody by main shaft tie-plate 5,4 fastening bolts 4, main shaft tie-plate 5 is associated with adjusting screw 3 by screw thread, and adjusting screw 3 is associated with top matrix by screw thread, and top matrix 1 associates with inner hole of workpiece.
Owing to adopting adjustable fixed length top, therefore when changing same class casing product, drawing the distance that need regulate according to the difference of sleeve pipe overall length, first with fork spanner or ratchet spanner, shaft stop nut 6 being unclamped a little; Again with special dismounting jacket casing in adjusting screw(rod) square head, be about the difference of sleeve pipe overall length toward counterclockwise rotating to the distance between nut inner face and tie-plate; Finally tighten stop nut with fork spanner or ratchet spanner.
