Abstract
The utility model relates to a multi-joint clamping fixture for assembling an interference-fit member, which is mainly provided with a steel tube installing clamping fixture body with a baffle at the end; venting holes are arranged on the installing clamping fixture body in the radial direction; the multi-joint clamping fixture is characterized in that the installing clamping fixture is provided with ladder-shaped seam allowances at one end corresponding to the baffle end, and the seam allowances are respectively spliced with a plurality of circular frustum shaped tubular joints with mother-openings. The multi-joint clamping fixture has the beneficial effects that the shortcoming that the specification of the original assembling clamping fixtures is excessive is improved, the assembling operation of bearings with different diameters and axial interference-fit members by using the original clamping fixture body is finished, the quality is ensured, the efficiency is improved and the cost is saved.
Description
Technical field
The utility model belongs to the mold of member assembling usefulness, relates in particular to a kind of polylinker mold of interference fit member assembling usefulness.
Background technology
Bearing adopts interference fit with the axle assembling.The bearing that specification is little, its assembling is relatively easy.Than relatively large bearing, the difficulty of assembly manipulation is bigger.The member diameter is big, then is difficult to guarantee the inner ring perpendicularity of bearing, if deviation, the assembling failure causes bearing to be scrapped.Prevailing method is to carry out hot charging with boil the heating bearing with oil, and this kind method is subjected to the limitation of condition, can not be extensive use of; Factory and the common bearing installation method of maintenance adopt the steel pipe of a kind of end band closure plate that mold is installed, and have steam vent on the mold body, finish the assembly work of bearing with the method that is pressed into.The mold diameter of steel tube requires the inner ring diameter more than or equal to bearing.Therefore, need be at a plurality of molds of the bearing system of different size, the invisible manufacturing cost that strengthens factory.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of polylinker mold of interference fit member assembling usefulness is provided, improve the too much deficiency of original assembling mold specification, utilize former mold body to finish the assembly work of plurality of specifications diameter bearing and axle interference fit member, ensure the quality of products, raise the efficiency, save cost.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of polylinker mold of interference fit member assembling usefulness, the steel pipe that mainly contains end band closure plate is installed the mold body, on installation mold body, radially have steam vent, it is characterized in that: correspondence one end that described installation mold body is equipped with the closure plate end is provided with stepped rim of the mouth, pegs graft with some truncated cone tubular configured joints that respectively have female mouthful respectively in described rim of the mouth.
Female mouth on the described truncated cone tubular configured joint is located at major diameter circular cone one end or minor diameter circular cone one end respectively.
Beneficial effect: improve the too much deficiency of original assembling mold specification, utilize former mold body to finish the assembly work of plurality of specifications diameter bearing and axle interference fit member, ensure the quality of products, raise the efficiency, save cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the joint design schematic diagram that female mouth is located at minor diameter circular cone one end.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides: see accompanying drawing for details, a kind of polylinker mold of interference fit member assembling usefulness, the steel pipe that mainly contains end band closure plate 1 is installed mold body 2, on installation mold body, radially have steam vent 3, correspondence one end that described installation mold body is equipped with the closure plate end is provided with stepped rim of the mouth 4, pegs graft with some truncated cone tubular configured joints 6 that respectively have female mouthful 5 respectively in described rim of the mouth.Female mouth on the described truncated cone tubular configured joint is located at major diameter circular cone one end or minor diameter circular cone one end respectively.Can satisfy the interference fit member assembling demand of different size bearing.
Using method:
Bearing holder (housing, cover) on the axial end of needs assemblings, is placed on the inner ring place of bearing to mold, little bearing can with "painted-face" character in opera directly cutter enter, big bearing, usually axle, bearing is placed under the hydraulic press, mold is placed on the inner ring place of bearing, utilizes hydraulic press to finish assembly work.
The diameter dimension of the steel pipe of mold body or joint diameter and the inner ring of the bearing that needs assembling should be identical or approaching, and a side that is connected with bearing is wanted processing plane, the end face of steel pipe or joint combines with bearing face closely like this, could guarantee that bearing is assembled to and does not have deviation on the axle.Have steam vent on the steel pipe of mold body, the steel duct of mold body can not produce pressure when mold is pressed bearing inward like this.Mold is not only applicable to the cooperation of bearing and axle, can also be used for copper sheathing, steel bushing, the assembling of parts such as gear.Also during the bearing of small dimension, just can use small-bore joint than mold steel pipe in assembling, the fastening mother-son mouth is connected on the mold body, and the side that osculum one end is connected with bearing is wanted processing plane, the end face of the end face of osculum and bearing combination closely like this.During than the bearing of the big specification of mold steel pipe, just can use big mouthful of joint fastening mother-son mouth to be connected on the mold body in assembling, the side that a big mouthful end is connected with bearing is wanted processing plane, makes the end face of big mouth and the end face combination closely of bearing.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. an interference fit member assembles the polylinker mold of usefulness, the steel pipe that mainly contains end band closure plate is installed the mold body, on installation mold body, radially have steam vent, it is characterized in that: correspondence one end that described installation mold body is equipped with the closure plate end is provided with stepped rim of the mouth, pegs graft with some truncated cone tubular configured joints that respectively have female mouthful respectively in described rim of the mouth.
2. the polylinker mold of interference fit member assembling usefulness according to claim 1 is characterized in that: the female mouth on the described truncated cone tubular configured joint is located at major diameter circular cone one end or minor diameter circular cone one end respectively.
