Description
Technical field
The utility model is related to a kind of automobile towing hook inclined-plane screw hole clamp for machining.
Background technology
Automobile towing hook shape is complex, needs multiple clip that could be carried out to it in the symmetrical screw hole on processing inclined-plane
Positioning, fixture dismounting is inconvenient, and after processing a screw hole, when being carried out to another screw hole, in order to meet two spiral shells
The concentricity in hole, must just measure towing hook and centering, not only inefficient, but also be susceptible to mismachining tolerance.
Invention content
The technical issues of the utility model solves is to provide a kind of automobile towing hook inclined-plane screw hole clamp for machining, for solving
Existing towing hook fixture is numerous, is susceptible to the not high problem of mismachining tolerance and processing efficiency.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of automobile towing hook inclined-plane screw hole clamp for machining, including pedestal are installed with bottom plate, the bottom of in pedestal side
It is fixed with a screw rod on plate and guide is installed, have pressure ring in screw jacket and nut is installed.
It is fixed with supporting block in pedestal side, is set in supporting block there are one pin hole, inserted with a guide pin in pin hole,
Guide pin upper end is fixedly connected with one piece of locating piece, is cased with spring outside the guide pin, both ends of the spring bear against locating piece with
In supporting block.
A stepped hole is equipped in bottom plate, guide one end is inserted in stepped hole, passes through between guide and stepped hole bottom surface
One plane bearing connection, is connected between guide outer wall and stepped hole inner wall by a ball bearing.
Further include position-limit mechanism, the position-limit mechanism includes that the limited screw that is connected in supporting block of screw rod and being opened in is led
Limiting slot on pin, limited screw one end are located in limiting slot.
The utility model has the beneficial effects that：In use, being sleeved on guide outside towing hook centre bore, pressure ring and spiral shell are then utilized
Mother positions towing hook, rotates 180 degree after processing one threaded hole of startup, then by towing hook, spring pushes locating piece patch
Tightly in threaded hole plane, it is positioned using locating piece, another threaded hole can be thus processed,
Reduce fixture dosage, improves processing efficiency and processing quality.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is the main structure diagram of the utility model,
Fig. 2 is the structural schematic diagram of the utility model when in use.
In figure：Pedestal 1, bottom plate 2, guide 3, pressure ring 4, screw rod 5, nut 6, limiting slot 7, guide pin 8, locating piece 9, spring
10, supporting block 11, pin hole 12, limited screw 13, towing hook 14, ball bearing 15, plane bearing 16.
Specific implementation mode
As illustrated in fig. 1 and 2, a kind of automobile towing hook inclined-plane screw hole clamp for machining, including a L-shaped pedestal 1, in pedestal
1 side is installed with bottom plate 2, is fixed with a screw rod 5 on a base plate 2 and is equipped with guide 3, pressure ring 4 is cased with outside screw rod 5
With nut 6 is installed.Automobile towing hook is positioned using guide 3, aspect lathe mills out inclined-plane and processes threaded hole.
Be fixed with supporting block 11 in 1 side of pedestal, set in supporting block 11 there are one pin hole 12, in pin hole 12 inserted with
A piece guide pin 8,8 upper end of guide pin are fixedly connected with one piece of locating piece 9, and spring 10,10 both ends of spring point are cased with outside the guide pin 8
It is not resisted against in locating piece 9 and supporting block 11.
The application method of the utility model is：
Pedestal 1 is fixed on processing center machine tool, then towing hook 14 is installed on fixture by the first step, and guide 3 is made to be inserted into
In towing hook centre bore, towing hook centre bore is positioned using guide 3, subsequent tightening nut 6, towing hook to be fixed,
Processing center machine tool first mills out a plane on towing hook inclined-plane and comes out, then drilling and tapping on this plane again, processing
Go out first threaded hole.
After second step, release nut 6, towing hook is rotated 180 degree by worker, and spring 10 pushes locating piece 9 to be resisted against the first spiral shell
In pit plane, using 9 centering of locating piece, then locking nut 6, second screw thread orifice of machining center pair are processed.
A stepped hole is equipped in bottom plate 2,3 one end of guide is inserted in stepped hole, is led between guide 3 and stepped hole bottom surface
It crosses a plane bearing 16 to connect, be connected by a ball bearing 15 between 3 outer wall of guide and stepped hole inner wall.In rotary mop
Hook is the rotation in bottom plate 2 of guide 3, and plane bearing 16 and ball bearing 15 are reduced and rubbed between guide 3 and bottom plate 2, so that rotation
After turning towing hook, spring 10 can have enough strength that locating piece 9 is pushed to be resisted against in first threaded hole plane, make operation
Get up more convenient.
Further include position-limit mechanism, the position-limit mechanism includes the limited screw 13 and open that screw rod 5 is connected in supporting block 11
The limiting slot being located on guide pin 8,13 one end of limited screw are located in limiting slot.Position-limit mechanism can prevent guide pin 8 from pin hole 12
Middle pop-up prevents guide pin 8 and spring 10 from losing.
