Abstract
The utility model relates to a bolt locking and anti-loosening device, which belongs to the field of machine tools. The bolt locking and anti-loosening device is provided with a bolt, and is characterized in that through holes are axially processed inside the bolt; two pin holes communicated with the through holes are processed at the tail end of the bolt; a short pin is placed in each pin hole, wherein a conical structure is arranged at the lower end of the short pin; a long pin is arranged in each through hole of the bolt, wherein a conical structure is arranged at the front end of the long pin; a thread with the diameter greater than that of the through hole is processed at the through hole at the head of the bolt; and an inner holding screw is screwed on the thread at the through hole. The bolt locking and anti-loosening device can avoid the looseness between parts and a machine tool body and also has the characteristics of simple structure, convenience in disassembly and good anti-loosening effect.
Description
Technical field
The utility model relates to the bolt locking mechanism field that lathe is used, and especially the machine tool component connection is locked locking device with bolt.
Background technique
As everyone knows, at present, it mainly is by bolt locking that the big parts of lathe connect, loosening in order to prevent that displacement takes place between parts, generally all installs locating stud between parts additional.Owing to structural reason, a lot of connection parts are difficult to install additional locating stud, and screw retention has just become important link like this, commonly used locking generally have following several: (1) nut lock washer locking (2) screw thread fastening glue is locking.The locking easy enforcement of nut lock washer, but nut must be added between part and the screw, bulk is strengthened, and anti-loosing effect is unsatisfactory; The locking enforcement of screw thread fastening glue is easy, and anti-loosing effect is also good, but also is difficult to adopt concerning the parts that require the split delivery to locate to reconnect the user.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, can play and prevent bolt locking locking device loosening between parts and the machine body.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bolt locking locking device, be provided with bolt, it is characterized in that the bolt inner shaft is to being processed with through hole, the bolt tail end is processed with two pin-and-holes that are connected with through hole, be placed with a short pin in each pin-and-hole, the lower end of short pin is a cone structure, be provided with in the through hole of bolt and have strong market potential, the front end of having strong market potential is a cone structure, the through hole of bolt head is processed with the screw thread of diameter greater than through hole, is installed with interior Cock screw on the screw thread of through hole.
The utility model also can be realized by following measure: be installed with outer Cock screw on the screw thread of the outer side through hole of interior Cock screw.
The beneficial effects of the utility model are, can play preventing outside the effect loosening between parts and the machine body, also have simple in structure, can be for convenience detach, the characteristics that anti-loosing effect is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, structural representation of the present utility model.
1. bolts are 2. had strong market potential among the figure, 3. short pin, 4. outer Cock screw, 5. interior Cock screw, the 6. parts that need lock of lathe, 7. machine body.
Embodiment
In Fig. 1, the utility model is provided with bolt 1, bolt 1 inner shaft is to being processed with through hole, bolt 1 tail end is processed with two pin-and-holes that are connected with through hole, be placed with a short pin 3 in each pin-and-hole, the lower end of short pin 3 is a cone structure, be provided with in the through hole of bolt 1 and have strong market potential 2,2 the front end of having strong market potential is a cone structure, the through hole of bolt 1 head is processed with the screw thread of diameter greater than through hole, Cock screw 5 in being installed with on the screw thread of through hole is installed with outer Cock screw 4 on the screw thread of interior Cock screw 5 outer side through hole.
When the utility model uses, the parts 6 that the lathe that will need earlier to lock need be locked are cleaned out, be positioned on the machine body 7 by matching requirements, align with tapped hole on the machine body 7 in hole on the parts 6 that lathe need be locked, two short pins 3 are filled in the hollow bolt 1, short pin 3 must not exceed the core diameter of thread of hollow bolt 1, then hollow bolt 1 is screwed in the tapped hole of machine body 7, the parts 6 that lathe need be locked connect as one with machine body 7, to have strong market potential this moment and 2 pack in the hollow bolt 1, the conical surface of front end of having strong market potential is corresponding with the conical surface of short pin 3 front ends, and then interior Cock screw 5 is screwed into making has strong market potential 2 moves to short pin 3, by the feasible short pin 3 of the jam-packed of conical surface side shifting outside the screw thread of hollow bolt 1, planar end surface until short pin 3 is close on the screw thread of machine body 7, because the effect that holds out against of short pin 3, made hollow bolt 1 not rotate easily this moment, played locking effect; And then outer Cock screw 4 is screwed into interior Cock screw 5 plays mutual locking effect, like this, played the effect that prevents that hollow bolt 1 is loosening by outer Cock screw 4, interior Cock screw 5 and the locking gear of having strong market potential 2, short pin 3 a series of parts constitute, thereby parts 6 and machine body 7 firm being connected as a single entity that lathe need be locked have been accomplished locking purpose good between parts.
Claims (2)
1. a bolt is locked locking device, be provided with bolt, it is characterized in that the bolt inner shaft is to being processed with through hole, the bolt tail end is processed with two pin-and-holes that are connected with through hole, is placed with a short pin in each pin-and-hole, and the lower end of short pin is a cone structure, be provided with in the through hole of bolt and have strong market potential, the front end of having strong market potential is a cone structure, and the through hole of bolt head is processed with the screw thread of diameter greater than through hole, is installed with interior Cock screw on the screw thread of through hole.
2. according to the described bolt of claim 1 locking locking device, it is characterized in that being installed with outer Cock screw on the screw thread of the outer side through hole of Cock screw in said.
