The tool can press two copper bushes in a center hole of the camshaft at the same time, so that the defect that in a conventional structure, the two copper bushes are pressed at twice can be overcome well.
Description
Technical field
The utility model belongs to frock clamp field, specifically, relates in particular to a kind of cam axial compression copper sheathing frock.
Background technology
Camshaft is that one is used mechanical part widely, and two copper sheathings are coaxially housed in the centre bore of this camshaft.At present, general first by a copper sheathing pressure-mounting in the centre bore of camshaft, then camshaft is changed to face, then from other end, another one copper sheathing is pressed in the centre bore of camshaft.
The defect of existing press-fit approach is: because two copper sheathings need to press-fit twice, operate very inconveniently, and it is very low to press-fit efficiency, is badly in need of solving above-mentioned technical barrier for this reason.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cam axial compression copper sheathing frock that efficiency is higher that press-fits, and wants two copper sheathings of synchronous press mounting.
The technical solution of the utility model is as follows: a kind of cam axial compression copper sheathing frock, it is characterized in that: comprise base plate (1), positioning sleeve (4) and positioning core axle (6), wherein on the end face of base plate (1), be installed with a holder (2), in holder, be coaxially installed with a positioning seat (3), the bottom surface of this positioning seat and base plate (1) end face is fixed; The number of described positioning sleeve (4) is one, the diameter of this positioning sleeve upper end is greater than the diameter at all the other positions, and the path section of positioning sleeve (4) is positioned between described holder (2) and positioning seat (3), and the large footpath section of positioning sleeve (4) is supported on described holder (2) end face by a packing ring (5);
The number of described positioning core axle (6) is one, and this positioning core axle is four-part form hierarchic structure, is followed successively by from top to bottom first, second and third and four shaft parts, and the diameter of first, second and third shaft part increases successively, and the equal diameters of third and fourth shaft part; The 4th shaft part of described positioning core axle (6) is positioned at the centre bore of positioning seat (3), and second and third shaft part of this positioning core axle is positioned at the centre bore of described positioning sleeve (4), and the 3rd shaft part of positioning seat (3) is supported on positioning seat (3) end face; The first shaft part top of described positioning core axle (6) is set with a gland (7), and these two parts are slidably matched, and gland (7) bottom is up big and down small two-part hierarchic structure.
While press-fiting, first first copper sheathing (T) is sleeved on to the bottom of described positioning core axle (6) first shaft parts, the end face laminating of the bottom surface of this copper sheathing (T) and positioning core axle (6) second shaft parts, then the positioning core axle (6) that camshaft (Z) is sleeved on to first copper sheathing (T) top is upper, and the laminating of the bottom surface of the end face of first copper sheathing (T) and camshaft (Z) centre bore; Secondly, again second copper sheathing (T) is sleeved on the positioning core axle (6) of camshaft (Z) top, finally described gland (7) is sleeved on the positioning core axle (6) of second copper sheathing (T) top, and drive gland (7) to press down by forcing press, thereby by two copper sheathings (T) synchronous press mounting in the centre bore of described camshaft (Z).
Adopt above technical scheme, the utility model can be by two copper sheathings (T) synchronous press mounting in the centre bore of described camshaft (Z), so just can overcome well traditional structure and press-fit at twice the defect of two copper sheathings, and of the present utility model simple in structure, easy to use laborsaving.
For the ease of forcing press is connected with gland (7), spy is provided with a cannelure (7a) on the top of this gland (7) periphery.
As preferably, described holder (2) is fixing with base plate (1) by the screw (8) vertically arranging.
Beneficial effect: the utility model can be by two copper sheathings (T) synchronous press mounting in the centre bore of described camshaft (Z), so just traditional structure can be overcome well and press-fit at twice the defect of two copper sheathings, and of the present utility model simple in structure, easy to use laborsaving.
