Abstract
The utility model discloses a connecting structure for a dish water motor end cap and a water pump. The connecting structure comprises a front end cap (1), a lower body (2) of the water pump and a connecting part (3), the motor end cap is an aluminum end cap, a stepped groove (4) is arranged on the end face of the motor front end cap, a groove (5) is disposed on the lower body of the water pump at a position close to the end surface, the connecting part is in thermal riveting with the motor front end cap and the lower body of the water pump, a projection (6) at one end of the connecting part matches with the stepped groove (4) on the end face of the front end cap while a wedge (7) at the other end of the connecting part matches with the groove (5) on the lower body of the water pump. As the front end cap and the lower body of the water pump are connected through the plastic connecting part via the thermal riveting structure, the connecting structure is firm in connection; and a bearing housing of the aluminum end cap can reach higher processing precision after being turned, and the motor can match with the water pump well, thereby reducing vibration and lowering noise.
Description
Technical field
The utility model relates to a kind of dish-washing machine motor water pump structure, especially relates to the draw bail of a kind of dish-washing machine motor end cap and water pump.
Background technology
The dish-washing machine pump motor is made of dish-washing machine motor and water pump, is the Power Drive Unit of dish-washing machine.Dish-washing machine pump motor reliability requirement height, environment for use are abominable, and motor directly links to each other with water pump, drip on the motor if leak, and just may leak electricity, security incidents such as puncture, fire, cause quality and potential safety hazard to the user.If electric motor end cap and water pump poor fit, after motor and water pump worked long hours, motor and water pump produce wearing and tearing, and drainage may take place, so the dish-washing machine end cap showed for extremely important with just connecting of water pump.
Traditional end cap has following two kinds of modes with the water pump connecting mode: 1. connecting of iron end cap and plastic water pump, because the material of iron end cap is thinner, be generally 1.0～1.5mm, the machining accuracy of iron end cap bearing chamber is not high simultaneously, and motor oscillating is bigger, and noise of motor is higher; 2. plastic end cover and plastic water pump connects; Because of the quality of fit of end cap bearing chamber and rolling bearing is had relatively high expectations, the machining accuracy of bearing chamber must be very high, the quality of fit of bearing and bearing chamber just can be high like this, noise of motor is low, and the precision of the bearing chamber of the injection molded working of plastics of plastic end cover is lower, and bearing chamber also is difficult to reach the machining accuracy that bearing chamber is had relatively high expectations after through processing, and the intensity of plastic end cover is not high simultaneously, motor easily produces bigger vibration, noise of motor height.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, connect the firm dish-washing machine motor end cap and the draw bail of water pump.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises motor drive end bearing bracket, water pump lower pump body and connector, described electric motor end cap is an aluminium end cap, the end face of motor drive end bearing bracket is provided with step trough, the proximal end face place of water pump lower pump body is provided with groove, adopt the hot riveting structure between described connector and motor drive end bearing bracket, the water pump lower pump body, the projection of connector one end cooperates with step trough on the drive end bearing bracket end face, and the wedge of the other end cooperates with groove on the water pump lower pump body.
Motor drive end bearing bracket described in the utility model cooperates circumferencial direction that four connectors evenly are set with the end face of water pump lower pump body.
The said structure that the utility model adopts, drive end bearing bracket and water pump lower pump body adopt the hot riveting structure by the connector of plastics, connect firmly; The bearing chamber of aluminium end cap can reach higher processing precision through turning, motor and water pump no-float, vibrate little, noise is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the front view of the utility model connector
Figure 3 shows that the vertical view of Fig. 2
Figure 4 shows that the A-A profile of Fig. 2
Figure 5 shows that the B-B profile of Fig. 2
The specific embodiment
By accompanying drawing as can be known, the draw bail of this dish-washing machine motor end cap and water pump comprises motor drive end bearing bracket 1, water pump lower pump body 2 and connector 3, described electric motor end cap is an aluminium end cap, the end face of motor drive end bearing bracket is provided with step trough 4, the proximal end face place of water pump lower pump body is provided with groove 5, adopt the hot riveting structure between described connector and motor drive end bearing bracket, the water pump lower pump body, the projection 6 of connector one end cooperates with step trough 4 on the drive end bearing bracket end face, and the wedge 7 of the other end cooperates with groove 5 on the water pump lower pump body.As optimal way of the present utility model, motor drive end bearing bracket 1 described in the utility model cooperates circumferencial direction that four connectors evenly are set with the end face of water pump lower pump body 2.
Aluminium end cap is thicker than iron end cap, and the bearing chamber of aluminium end cap is processed through turning, can reach higher processing precision and form good cooperating with bearing, and the end cap seam is processed through turning simultaneously, and end cap seam and bearing chamber have axiality preferably.End cap and water pump by four plastic connecting components plastic water pump and aluminium matter drive end bearing bracket after ultrasonic heat is riveted, the water pump center with good through the bearing chamber center axiality of turning aluminium matter end cap, motor and water pump after long-term running, no-float, motor oscillating is little, noise is low, can not leak.
Claims (2)
1. the draw bail of dish-washing machine motor end cap and water pump, comprise motor drive end bearing bracket, water pump lower pump body and connector, it is characterized in that described electric motor end cap is an aluminium end cap, the end face of motor drive end bearing bracket is provided with step trough, the proximal end face place of water pump lower pump body is provided with groove, adopt the hot riveting structure between described connector and motor drive end bearing bracket, the water pump lower pump body, the projection of connector one end cooperates with step trough on the drive end bearing bracket end face, and the wedge of the other end cooperates with groove on the water pump lower pump body.
2. the draw bail of a kind of dish-washing machine motor end cap according to claim 1 and water pump is characterized in that described motor drive end bearing bracket cooperates circumferencial direction that four connectors evenly are set with the end face of water pump lower pump body.
