Abstract
The invention provides an inserting type stud assembly and disassembly clamp which mainly comprises a clamp body, a retainer, three pin rollers and a baffle ring. Grooves in the proper number form a cavity of the clamp body, the retainer is placed in the cavity and provided with three cylindrical grooves, and the baffle ring is connected to the bottom of the clamp body through a fastening screw. In the process of assembly, the inserting type stud assembly and disassembly clamp is inserted into a stud, when the clamp body is rotated, the retainer relatively stands still, groove faces in the cavity of the clamp body squeeze the pin rollers so as to clamp the stud, and clamping is convenient; after the stud is screwed tightly, the clamp body is slightly rotated in the opposite direction, and then the clamp can be disassembled. The inserting type stud assembly and disassembly clamp is convenient to clamp and disassemble, and capable of reducing labor intensity and improving work efficiency; a large number of contact points of the pin rollers and threads exist, the pin rollers are made of wearable bearing steel, and service life is long; meanwhile, the clamp can screw threads with different pitches and even a stud with threads at only one end, and application range is wide.
Description
Technical field:
The present invention relates to a kind of studs loading and unloading clamp.
Background technology:
Mainly adopt the screw-in loading and unloading clamp during studs assembling at present, this fixture is when assembling, need first fixture to be screwed on the stud head that will install, and then adopt pneumatic or hydraulic spanner that double-screw bolt is screwed into to corresponding screwed hole, need fixed bolt during dismounting, the opposite spin fixture, separate fixture with double-screw bolt.
Screw-in loading and unloading clamp clamping, the dismounting required time long, the loading and unloading amount is large, labour intensity is high, and screw thread is frequently stressed, service life is short.
Summary of the invention:
In order to overcome the defect of existing screw-in loading and unloading clamp, the invention provides a kind of plug-in type studs loading and unloading clamp, plug-in type studs loading and unloading clamp by chuck body, retainer, 3 rollers, baffle ring, and holding screw form.
Wherein, chuck body top 0.5-1 cun interior square hole is for the square feather joint with electric wrench or pneumatic impact spanner, and bottom forms die cavity by appropriate groove, and depression peak and the minimum point of groove differ the 0.8-1.5 millimeter, when handling, are enclosed within on double-screw bolt; Retainer is placed in the die cavity of chuck body bottom, for cylinder type, its length is than the lower slightly 0.3-0.7 millimeter of clamp body depth of cavity, external diameter is less than the chuck body die cavity internal diameter 0.3-0.5 of minimum place millimeter, internal diameter is greater than double-screw bolt external diameter 0.3-0.5 millimeter, and retainer thickness is than the little about 0.8-1.5 millimeter of roller diameter dimension, and wherein average mark is furnished with three cylindrical grooves along axis direction, the cylindrical groove diameter is greater than roller diameter 0.4-1.5 millimeter, and length is not less than roller length; 3 rollers are placed in the cylindrical groove of retainer, roller external diameter 4-10 millimeter, and length is not less than double-screw bolt threaded one end size; The chuck body bottom is provided with baffle ring, by holding screw, with chuck body, is connected, and prevents roller and retainer landing.
The multiple that groove quantity on described chuck body is 3, after loading and unloading clamp is used the certain wearing and tearing of appearance, replaceable 1 cover roller, be positioned in new groove, can continue to use.
On described retainer, the middle mind-set retainer external diameter of cylindrical groove is offset about 0.2-0.7 millimeter.
Described roller adopts anti-friction bearing steel making, long service life.
Described baffle ring internal diameter is identical with the retainer internal diameter.
When assembling, owing between double-screw bolt and roller, having gap, only plug-in type studs loading and unloading clamp need be inserted on double-screw bolt and get final product, clamping is very convenient; When the rolling clamp body, retainer is relatively static, chuck body die cavity inner groove faces extruding roller, thus clamp double-screw bolt, now can adopt pneumatic or hydraulic spanner that double-screw bolt is screwed into to corresponding screw; After screwing up stud, slightly to opposite spin chuck body, i.e. releasable clamp.
A kind of plug-in type studs loading and unloading clamp of the present invention, clamping, move back and unload conveniently, can reduce labor intensity, increase work efficiency; Roller and screw thread contact point are many, and adopt anti-friction bearing steel making, long service life; Simultaneously, this fixture can be tightened the screw thread of different pitch, even can tighten the only threaded double-screw bolt of an end, widely applicable.

In figure: 1, chuck body; 2, retainer; 3, roller; 4, holding screw; 5, baffle ring.
The specific embodiment:
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 shows a kind of structure of plug-in type studs loading and unloading clamp, it by chuck body (1), retainer (2), 3 rollers (3), baffle ring (5), and holding screw (4) form.
Wherein, chuck body (1) top 0.5-1 cun interior square hole is for the square feather joint with electric wrench or pneumatic impact spanner, and bottom forms die cavity by appropriate groove, and depression peak and the minimum point of groove differ the 0.8-1.5 millimeter, when handling, are enclosed within on double-screw bolt; Retainer (2) is placed in the die cavity of chuck body (1) bottom, for cylinder type, its length is than the lower slightly 0.3-0.7 millimeter of clamp body depth of cavity, external diameter is less than chuck body (1) the die cavity internal diameter 0.3-0.5 of minimum place millimeter, internal diameter is greater than double-screw bolt external diameter 0.3-0.5 millimeter, retainer (2) thickness is than the little about 0.8-1.5 millimeter of roller (3) diameter dimension, wherein average mark is furnished with three cylindrical grooves along axis direction, the cylindrical groove diameter is greater than roller (3) diameter 0.4-1.5 millimeter, and length is not less than roller (3) length; 3 rollers (3) are placed in the cylindrical groove of retainer (2), roller (3) external diameter 4-10 millimeter, and length is not less than double-screw bolt threaded one end size; Chuck body (1) bottom is provided with baffle ring (5), by holding screw (4), with chuck body (1), is connected, and prevents roller (3) and retainer (2) landing.
