Abstract
The utility model provides a manual jig for installing a small diameter axletree. The manual jig for installing a small diameter axletree comprises a base and a column. The column is vertically arranged on the upper end of one side of the base, the column is sleeved with a support arm and the height of the arm can be adjusted. A compression rod penetrates a through hole of the other end of the support arm and an elastic device is arranged between the upper portion of the compression rod and the upper end surface of the support arm. The lower end of the compression rod is provided with a drill chuck, the drill chuck clamps a pressure head, an installation hole is formed in the lower end of the pressure head and is in interference fit with an outer diameter of the axletree, and a work piece is fixed on the upper end surface of the base. The manual jig for installing the small diameter axletree is in common use in a certain scope, simple in structure, reliable in working, low in cost and high in practical value.
Description
Technical field
The utility model relates to a kind of manual for the small-diameter bearings installation, is used for the installation of Small Diameter Precision bearing.
Background technology
The at present assembling of miniature precision product small-medium size precision bearing can't directly be installed with hand, and there is the magnitude of interference in quiet circle fitted position, can't guarantee vertically to pack into, is easy to chew part.If it is bad that bearing is installed, can affect the flexibility of part rotating part motion, affect properties of product, also can greatly shorten bearing service life, therefore be necessary improvement.
The utility model content
The technical problem that the utility model solves: a kind of manual for the small-diameter bearings installation is provided, can realizes the installation to the minor diameter rolling bearing, and accomplish fast, efficiently, precisely.
The technical solution adopted in the utility model: be used for the manual that small-diameter bearings is installed, have base and column, described column vertically is built up in base one side upper end, be set with height adjustable support arm on the described column, depression bar passes between the through hole of the support arm other end and depression bar top and the support arm upper surface and is provided with elastic device, the depression bar lower end is provided with drill chuck, described drill chuck clamps pressure head, described pressure head lower end is shaped with the installing hole with the bearing outside diameter interference fit, and workpiece is fixed on base opposite side upper surface.
Further, described support arm one end is shaped with installing hole and is sleeved on the column, and described arm end is shaped with screwed hole, and holding screw screws in screwed hole with support arm and column locking.
Further, described elastic device is spring.
Further, described pressure head adopts nylon material to make.
Further, described installing hole and bearing outside diameter value of interference fit are the 2-3 micron.
The utility model compared with prior art within the specific limits can be general, and simple in structure, easy to operate, reliable operation, and cost is low, has higher practical value.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
Be used for the manual that small-diameter bearings is installed, have base 8 and column 1, described column 1 vertically is built up in base 8 one sides upper end, be set with height adjustable support arm 4 on the described column 1, specifically, described support arm 4 one ends are shaped with installing hole 14 and are sleeved on the column 1, and described support arm 4 ends are shaped with screwed hole 12, and holding screw 2 screws in screwed hole 12 with support arm 4 and column 1 locking.Depression bar 5 passes between the through hole 13 of support arm 4 other ends and depression bar 5 tops and support arm 4 upper surfaces and is provided with elastic device, preferred spring 3.Depression bar 5 lower ends are provided with drill chuck 6, described drill chuck 6 clamps pressure head 7, pressure head 7 preferred nylon materials are made, described pressure head 7 lower ends are shaped with the installing hole 9 with bearing 10 external diameter interference fit, stating installing hole 9 is the 2-3 micron with bearing 10 external diameter value of interference fit, and workpiece 11 is fixed on base 8 opposite side upper surfaces.
Operation principle of the present invention: clamp pressure heads 7 with drill chuck 6, with bearing 10 pressure head 7 of packing into, workpiece 11 moves on to pressure head 7 belows, gives depression bar 5 afterburning vertically downward, and pressure head 7 pushes the position that workpiece 11 needs to install bearing 10 with bearing 10.At first according to the height of the Height Adjustment support arm 4 of workpiece 11, unclamp holding screw 2, support arm 4 slides up and down along column 1, be transferred to proper height after, holding screw 2 is tightened up.Then according to the suitable installation way of the structure choice of workpiece 11, the workpiece 11 that clips is placed pressure head 7 belows, it is coaxial with pressure head 7 to make workpiece 11 need be pressed into the position of bearing 10.Pressure head 7 adopts industrial nylon material, can prevent from bringing hard foreign matter into bearing 10, and it produces the cut equivalent damage to precision bearing in the time of can avoiding being pressed into metal fixture.Pressure head 7 is structurally processed the installing hole 9 identical with being pressed into bearing 10 external diameter basic sizes, adopt zero to several microns interference fit (such as the 2-3 micron), installing hole 9 end faces are vertical with bearing 10 axis, guarantee the horizontally mounted pressure head 7 of bearing 10 energy, and can not fall.Drill chuck 6 links together with depression bar 5, clamps pressure head 7 with the moving drill chuck 6 of hand-screw.All be lifted at the effect down-pressed pole 5 of spring 3 and drill chuck 6, pressure head 7 when not working; Bearing 10 pressure head 7 of packing into during work gives depression bar 5 afterburning vertically downward, and pressure head 7 vertically pushes the position that workpiece 11 needs to install bearings 10 with bearing 10.Need guarantee in the process of press in that workpiece 11 is coaxial with bearing 10 centerings, thereby can accomplish that vertical exactly is pressed into.Because workpiece 11 needs the pressing part size magnitudes of interference larger with bearing 10, be pressed into rear depression bar 5 and lift so finish, can not be with bearing running 10.No matter being pressed into, bearing inner race, outer ring all can.Only need change pressure head 7 to the bearing of different size gets final product.According to the workpiece height, the height of regulating support arm 4 can be general.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalences of being done with the described content of the utility model claim change, all should be included within the utility model claim scope.
