A kind of automobile power steering gear assembly assembly tool
Technical field:
The utility model relates to a kind of automobile power steering gear assembly assembly tool, belongs to automobile power steering gear assembly assembly tool technical field.
Background technology:
Existing automobile power steering gear assembly assembly technology is being changed to automatic assembling by hand assembled, on automatic assembly line in the pressing bearing, because depression bar is a matched in clearance with the bearing that needs assembling, for prevent that bearing from coming off from pressure head in press-fiting process, generally employing is manual coats grease with brearing bore earlier, bearing is contained on the pressure head to be pressed into then.This assembling mode is not only bad for the whether neglected loading of assembly line monitoring bearing, and each bearing all wants artificial apply grease, influences the cleannes of automobile power steering gear assembly production process.
Summary of the invention:
The purpose of this utility model is, provide on a kind of pressure head that is installed in traditional press-loading device, in assembling process, do not need artificial manual apply grease, realize unmanned operation, whole process can be finished by equipment fully automatically, and can improve the operating efficiency of assembly assembling greatly by the whether neglected loading of equipment automatic monitoring bearing; And simple in structure, the automobile power steering gear assembly assembly tool of low cost of manufacture.
The utility model is achieved by the following technical solution:
A kind of automobile power steering gear assembly assembly tool, it is made up of depression bar, compression spring, steel ball and lock-screw, it is characterized in that: the depression bar central upper portion is manufactured with a centre bore that cooperates with pressure head, the depression bar bottom be manufactured with one with the lateral aperture of depression bar axis normal; Side in the lateral aperture is equipped with steel ball, and opposite side is equipped with lock-screw, and the compression spring is housed between steel ball and the lock-screw.
The utility model beneficial effect compared with prior art is:
This automobile power steering gear assembly assembly tool is assemblied on the pressure head of traditional press-loading device, utilize steel ball under the effect of compression spring, eliminate the gap between bearing and the depression bar, thereby make depression bar in the process that the dress last item holds, bearing not can because of and depression bar between have the gap and drop, the whole process of pressing bearing is finished automatically by equipment, realize unmanned operation, avoided in process of production because the operate miss that human factor causes, can realize the whether neglected loading of equipment automatic monitoring bearing, not only reduce production cost, and improved the efficient of assembly work greatly.Solved traditional press-loading device and will adopt and manual earlier brearing bore is coated grease, bearing has been contained on the pressure head is pressed into then, inefficiency, the cleannes in the power steering gear assembly production process can not guarantee, also occur the problem of neglected loading easily.
Description of drawings:
Fig. 1 is a kind of structural representation of automobile power steering gear assembly assembly tool;
Fig. 2 is the structural representation that a kind of automobile power steering gear assembly assembly tool is applied to the steering gear assembling process;
Fig. 3 is the structural representation of side cover.
Among the figure: 1, depression bar, 2, the compression spring, 3, steel ball, 4, lock-screw, 5, centre bore, 6, lateral aperture, 7, bearing, 8, side cover.
The specific embodiment:
This automobile power steering gear assembly assembly tool is made up of depression bar 1, compression spring 2, steel ball 3 and lock-screw 4, the center on depression bar 1 top be manufactured with one with the centre bore 5 of the pressure head stationary fit of press-loading device, the bottom of depression bar 1 be manufactured with one with the lateral aperture 6 of the axis normal of depression bar 1, the lateral aperture 6 wherein outlet diameter of a side is smaller, and opposite side is manufactured with internal thread.In the smaller side of lateral aperture 6 outlet diameters steel ball 3 is housed, the smaller purpose of diameter is to prevent that steel ball 3 from dropping out, and lateral aperture 6 is made female opposite side lock-screw 4 is housed, and is equipped with between steel ball 3 and the lock-screw 4 and compresses spring 2 (referring to accompanying drawing 1).
When this automobile power steering gear assembly assembly tool uses, the centre bore 5 of depression bar 1 is sleeved on the pressure head of press-loading device, can works with press-loading device.Now be assembled into example in automobile power steering side cover bearing and be illustrated (referring to accompanying drawing 2-3) with this tool applications, side cover 8 is placed on the firm banking of assembly equipment, automatically bearing 7 is contained on the depression bar 1 by manipulator again, though depression bar 1 is a matched in clearance with the bearing that needs assembling, but steel ball 3 is under the effect of compression spring 2, can eliminate the gap between bearing 7 and the depression bar 1, thereby depression bar 1 is held in 7 the process at the dress last item, bearing 7 not can because of and depression bar 1 between have the gap and drop.
