Abstract

The utility model relates to an assembly tool for bearings, carriers and clamp springs, which comprises a pressing head, a clasping sleeve for clamp springs and a positioning seat. The clasping sleevefor clamp springs is coaxial with the positioning seat and mutually matched with the positioning seat through a positioning surface. The clasping sleeve for clamp springs comprises an upper chamber and a lower chamber, and the upper chamber is in the shape of a reverse cone. Compared with traditional assembly modes, the assembly tool has the following advantages that the assembly tool can be installed on a common pressing machine for assembly, and clamp springs are pressed and assembled by the pressing machine rather than manually assembled, so working intensity can be reduced; the events that the clamp springs are forgot to be assembled or not assembled in the correct positions can be effectively prevented (combining the automatic detection function of the pressing machine for force andshift), and the assembly quality of the clamp springs is effectively improved; bearing and the clamp springs are pressed together, which saves one working procedure.

Description

The assembly tooling of support of bearing jump ring

Technical field

The utility model relates to a kind of special tooling, relates in particular to a kind of frock that is used for truck drive shaft upper bearing (metal) support and jump ring assembling.

Background technology

Support of bearing sub-unit is an accessory more common on the power transmission shaft product, and by bracket shell, bearing, and interior jump ring is formed.Its traditional assembling mode is earlier on press bearing to be pressed into bracket shell, again with Circlip tongs with in the jump ring card entry slot.This artificial jump ring assembly method has following shortcoming: one, exist the jump ring neglected loading or not in place (be jump ring do not snap in the jump ring groove or only a part snap in the jump ring groove) hidden danger of quality; Two, adorn by artificial hand vice, labour intensity is bigger.

The utility model content

The technical problems to be solved in the utility model provides a kind of support of bearing jump ring that is used for and assembles, and is different from the frock of traditional assembling mode.

The utility model is by the following technical solutions:

The assembly tooling of a kind of support of bearing jump ring comprises that pressure head, jump ring tighten up cover and positioning seat, and jump ring tightens up that cover cooperatively interacts by locating surface with positioning seat and be coaxial; Described jump ring tightens up and comprises upper and lower chamber in the cover, and epicoele is an inner conical.

Preferably, comprise also that guide pillar is coaxial to be connected on the positioning seat that the internal diameter of guide pillar external diameter and bearing matches.The guide pillar effect is to avoid bearing to put into the bracket shell run-off the straight, makes things convenient for the workman to operate.

Preferably, described jump ring tightens up to put and is provided with pressure-bearing surface, and described pressure-bearing surface leans on mutually with the upper surface of bracket shell.

The utility model transmits power and motion by pressure head, tightens up cover by jump ring and realizes jump ring the tightening up before the bracket shell of packing into.Positioning seat is used for the locating support housing, and jump ring tightens up cover and is pressed on the bracket shell by pressure-bearing surface, and it is coaxial with the counterbore of bracket shell to guarantee indirectly that by locating surface jump ring tightens up the inner conical surface of cover simultaneously.Pressure head promotes jump ring (and bearing), and jump ring tightens up cover can allow jump ring tighten up gradually along the conical surface, and enters in the bracket shell, and when complete corresponding jump ring groove position, jump ring flicks.This shows that the utility model is to realize press-fiting by press, and simple in structure, easy to operate.Because pressure head is parallel jump ring to be pressed onto the end, do not exist jump ring to press situation not in place yet.

More traditional assembling mode behind employing the utility model, has following tangible advantage:

1. can be contained on the common press and use, become the manual spring that is installed and press-fit, thereby can reduce labour intensity into press;

2. can effectively avoid jump ring neglected loading (need) or adorn situation not in place taking place, effectively improve the jump ring assembly quality in conjunction with the automatic measuring ability of press to power and displacement;

3. bearing, jump ring are pressed into synchronously, save a procedure.

Description of drawings

Fig. 1 is a structural representation of the present utility model, the locations of structures when being depicted as jump ring and being about to be pressed into.

The specific embodiment

See Fig. 1, the utility model is made up of four critical pieces: pressure head 1 is loaded on the press slide, with jump ring 8 and bearing 7 parallel depressing; Guide pillar 2 is connected with positioning seat 4 by sunk screw 5, and coaxial with positioning seat 4, and its external diameter and bearing 7 internal diameters match, and makes things convenient for bearing 7 to put into (bearing is put into to tilt); Jump ring tightens up cover 3, coaxial with it by cooperating with the periphery 13 of positioning seat 4, pressure-bearing surface 14 leans on mutually with bracket shell 6 upper surfaces, jump ring tightens up in the cover 3 and is divided into upper and

lower chamber

12,11, epicoele 12 is inner conical, the big end of this taper 12 can hold the jump ring 8 under the free state, and smallest end is then consistent with the aperture of bracket shell 6; The lower end of pressure head can effectively be pressed onto jump ring, and the path with epicoele 12 keeps certain interval again, and is when avoiding pressure head 1 to pass through, former thereby cause pressure head 1 to run into the epicoele conical surface because of equipment deviation etc.; Positioning seat 4 is contained on the location counterbore of platen 10, with pressure head 1 essentially concentric (guaranteeing by lathe), and tightens up cover 3 and bracket shell 6 provides the location for jump ring.

During assembling, at first bracket shell 6 is put into positioning seat 4, put down jump ring then and tighten up cover 3, match by locating surface 13 and positioning seat 4, be pressed on the upper surface of bracket shell 6 by pressure-bearing surface 14 simultaneously, get bearing 7 again and be enclosed within on the guide pillar 2, bearing 7 generally can be by the deadweight landing to join with bracket shell 6 (bearing 7 be interference fits with bracket shell 6), again jump ring 8 is put into, controlled the lathe button at last, allow pressure head 1 depress and get final product.When jump ring 8 was depressed into complete corresponding jump ring groove position, jump ring 8 can flick and embed in the jump ring groove, because the upper surface of bearing 7 is a little more than the lower edge of jump ring groove, so pressure head 1 can not damage the jump ring groove by pressure.After being pressed into end, pressure head 1 is gone up by press control.Take off jump ring earlier and tighten up cover 3 this moment, and then the support of bearing sub-unit that installs is taken off from guide pillar 2, so just finished once to press-fit.

All have pressure and displacement detection device on the general press, pressure head can directly be contained on the pressure sensor of press top shoe.See Fig. 1, pressure head 1 top is a nipple 9, can directly be screwed on the pressure sensor.When jump ring is arranged, to being pressed into end position normally, pressure head 1 will lean on extremely with jump ring 8 and bearing 7, and produce a bigger shock loading; If jump ring neglected loading, Equipment Inspection can be very little to the power that is pressed into of this position, thereby setting program (is preset between the displacement field when normally being pressed onto the end in view of the above, force value when the detection pressure head is depressed into this position), automatically whether neglected loading is also in time reported to the police to judge jump ring by press, thereby effectively realizes preventing the jump ring neglected loading.

The utility model is less demanding to press, if by on the cylinder put or the oil cylinder simple press that directly drives slide block work.But for fear of power is excessive to cause damage to workpiece because of being pressed into, the specified power of being pressed into of suggestion press is not more than 5 tons.
