Specific embodiment
For the technology contents of the utility model, construction feature, the objects and the effects are described in detail, below in conjunction with implementation
Mode simultaneously coordinates attached drawing to be explained in detail.
With reference to Fig. 1 and Fig. 2, this practicality newly discloses a kind of 1 fixture of expanding arbor, which includes expandable expanded core
Axis 1 and rotatable cam pin 3, be equipped in expanding arbor 1 can along the swelling part of the axial movement of expanding arbor 1, cam pin 3 with
Swelling part is connected and drives axial movement of the swelling part along expanding arbor 1 by the rotation of cam pin 3.Cam pin 3 and swelling
This between part is connected, both can be connected directly or add certain connector between the two and realize it is connected,
As long as ensure cam pin 3 rotate can synchronous drive swelling part axial movement.In the prior art, expanding arbor 1 presss from both sides
The structure of tool is as shown in figure 3, this clamp structure is manually stubborn swelling part so that swelling part is axially moveable and causes swollen
Expansion core axis 1 expands.Time-consuming for this mode, and is difficult to hold the degree of expansion, i.e. the clamping dynamics to workpiece.And this programme,
Cam pin 3 is applied to founding property this, the axial movement of swelling part is driven using the rotation of cam pin 3.Meanwhile in bias
Under the action of pin 3, the distance that swelling part moves every time is all certain value, and then ensure that each clamping dynamics is the same, and clamping
Workpiece take it is short, it is efficient.
Preferably, one end of the expanding arbor 1 is the fixture head for clamping workpiece, and the cam pin 3 is located at phase
For the other end on fixture head., it can be achieved that the progressively expansion of expanding arbor 1 when swelling part is progressively moved to 3 one end of cam pin.
Preferably, the swelling part is equipped with the along 1 radial direction of expanding arbor in one end away from the fixture head
One pin hole, the cam pin 3 are inserted in the pin hole.I.e. cam pin 3 can directly be connected with one end of swelling part and drive swelling part
It is mobile.In addition, a fixture fixed seat 4, the pedestal piston are connected compared with the other end on fixture head on the expanding arbor 1
5 are located in fixture fixed seat 4, and the second pin hole along 1 radial direction of expanding arbor is offered in fixture fixed seat 4, and the cam pin 3 is same
When be inserted into the second pin hole and the first pin hole.
Preferably, the swelling part is connected with a pedestal piston 5, pedestal piston 5 in one end away from the fixture head
On along the radial direction of the expanding arbor 1 offer the first through hole 51, the cam pin 3 is inserted in first through hole 51.I.e.
Cam pin 3 is indirectly connected with swelling part by pedestal piston 5 and swelling part is driven to be axially moveable.In addition, the expanding arbor 1
On compared with the other end on fixture head connect a fixture fixed seat 4, the pedestal piston 5 is located in fixture fixed seat 4, fixture
The second through hole 41 along 1 radial direction of expanding arbor is offered in fixed seat 4, the cam pin 3 is simultaneously through the second through hole 41
With the first through hole 51.
Preferably, the swelling part is a wedge piece or is a swelling screw 2, axially leads to for one in the expanding arbor 1
Hole, the swelling part are inserted into expanding arbor 1 from fixture head one end on expanding arbor 1.
Preferably, the swelling part is swelling screw 2, and the head of swelling screw 2 includes male cone (strobilus masculinus), the expanding arbor 1
The fixture head of one end includes inner conical surface, and inner conical surface is contacted and is engaged with male cone (strobilus masculinus).When i.e. cam pin 3 rotates, swelling screw 2
It moves in the axial direction, meanwhile, the inner conical surface on the male cone (strobilus masculinus) extrusion clamp head on 2 head of swelling screw so that the head of expanding arbor 1
The gradual distending in portion, and then swelling workpiece, achieve the purpose that clamping.
Preferably, in the fixture fixed seat 4 for one along the axial through hole of expanding arbor 1, the pedestal piston 5 and swelling
Other end screw thread of the screw 2 away from the fixture head is linked in the through hole of fixture fixed seat 4.2 one end of swelling screw is spiral shell
Line, pedestal piston 5 are threadedly coupled more suitable therewith.But swelling screw 2 its motion mode in this programme is not the prior art
In be rotationally advancing, i.e., screw turned under progression, but translated under the action of cam pin 3 directed along axial
Movement.
Preferably, 3 both ends of cam pin are not of uniform size, and smaller one end is socketed with shaft block ring 6, larger one end edge
The radial direction of cam pin 3 offers hole.Fixture fixed seat 4 and pedestal piston 5 are inserted into simultaneously using 3 smaller one end of cam pin,
And smaller one end is socketed on using shaft block ring 6, prevent coming off for cam pin 3.Meanwhile for the ease of rotating the cam pin 3,
It can open up and portal in the larger one end of cam pin 3, gripping member, such as a rod piece are inserted into the hole, then holds the gripping member
And cam pin 3 is rotated, and synchronous drive swelling screw 2 is moved axially along 3 one end of cam pin, final swelling workpiece simultaneously realizes clamping
Purpose.
Clamp structure in the utility model drives swelling part to be moved along the axial direction of expanding arbor using the rotation of cam pin
It is dynamic, so that expanding arbor expands and expansible clamping of workpieces.This clamping Structural Design of Shaft is ingenious, each rotation meeting of cam pin
Swelling part is driven to move axially same distance, then all, clamping is also all each time for the degree that expanding arbor expands each time
It is same dynamics, without torsion, static clamping, repetitive positioning accuracy height.Compared with needing to turn swelling screw in the prior art
It is then more convenient simple and quick that cam pin is directly rotated for making the clamping structure of expanding arbor swelling, in this programme, it can be big
Width shortens the clamping time, improves work efficiency.
Herein first, second ... only represents the differentiation of its title, what significance level and the position for not representing them have
It is different.Herein, up, down, left, right, before and after only represents its relative position and does not indicate that its absolute position.The foregoing is merely this
The embodiment of utility model, it does not limit the scope of the patent of the present invention, it is every using the utility model specification and
The equivalent structure or equivalent flow shift that accompanying drawing content is made directly or indirectly is used in other related technical areas,
Similarly it is included in the scope of patent protection of the utility model.
