Description

Warm-air drier joint assembly fixture

Technical Field

The utility model belongs to the technical field of automobile air conditioners, and relates to an assembly fixture for a fan heater joint.

Background

The warm air core is one of the components of the automobile air conditioning system and is mainly used for air conditioning and heating in the cab. The working principle of the warm air core body is that the heat exchange is carried out on engine cooling liquid flowing through the inside through the aluminum core body, and hot air is blown out through the air outlet under the action of the blower. When the warm air machine core body is assembled, the two water chambers are firstly arranged at two sides of the core body respectively, and then the joint is arranged on the core body in a knocking way. Because the parts have dimensional deviation, the position matching property of the main chip of the core body, the water chamber and the joint is considered when the main chip of the core body and the water chamber are assembled together, and the position of the tooling needs to be adjusted every time so as to improve the assembly precision. The manual adjustment has low assembly work efficiency, high labor cost and low product qualification rate.

Therefore, the utility model aims to solve the assembly problem of the fan heater joint and provide an assembly tool of the fan heater joint.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

a warm air blower joint assembly fixture comprises a mounting seat and an elastic expansion core; the mounting seat is internally provided with a through hole, one end of the through hole is provided with an error-proof mounting hole, the shape of the error-proof mounting hole is matched with the shape of the connector, the connector is placed in the error-proof mounting hole, and the end face of the connector is attached to the end face of the error-proof mounting hole; the elastic expansion core is arranged in the through hole; one end of the elastic expansion core, which is close to the error-proof mounting hole, is provided with a plurality of elastic sheets which are circumferentially distributed at intervals; one end of the elastic sheet is arc-shaped, and all the elastic sheets form an elastic ball head which can elastically shrink along the radial direction of the elastic expansion core; the elastic ball head is arranged in an inner hole of the joint and is used for expanding the joint under the elastic action.

Further, a positioning hole is formed in the outer wall of the elastic expansion core, a threaded hole located on the through hole wall is formed in the mounting seat, a locking screw is arranged in the threaded hole, one end of the locking screw is screwed into the positioning hole, and the elastic expansion core is fixed.

Further, the diameter of the elastic ball head in the initial state is 0.5mm larger than the inner diameter of the joint. The elastic ball head has an arc guiding function, so that the connector is easy to install, but after the connector is installed in place, the elastic ball head can lock the connector through resilience force, and the connector is guaranteed not to fall easily. After the joint is assembled with the core body main sheet and the water chamber, the joint can easily fall off from the spherical universal positioning structure because the joint belongs to interference fit, and the joint is large in contact area and friction resistance.

Further, the elastic expansion core is far away from one end of the error-proof mounting hole, an alignment groove is formed in one end of the alignment groove on the mounting seat, an alignment line is arranged at one end of the alignment groove, and the alignment groove and the alignment line are collinear through rotating the elastic expansion core, so that circumferential positioning is realized.

The utility model has the beneficial effects that:

according to the utility model, the error-proof mounting holes are formed according to the shape of the connector, so that the correct direction of the connector after the connector is mounted, the end face of the connector is flatly attached to the end face of the tool, and the connector is ensured not to shake up and down and left and right on the tool, and the position is stable. And utilize the elasticity core that expands to fix, because core body principal piece, hydroecium are interference fit with the joint, can't disassemble easily or produce relative displacement after the equipment together, after the equipment finishes, the mount pad can return the origin position along with equipment is automatic, and the elasticity bulb can take place to break away from with the joint voluntarily, and can not influence the installation effect of joint.
