A kind of micro-machine support
Technical field
The utility model relates to motor fixing device, particularly a kind of micro-machine support.
Background technology
Micro-machine does not generally have shell, and in the time of fixedly, its stator directly is fixed on the support.Motor needs to bear moment of torsion and vibration in rotation process, and described moment of torsion and vibration can be delivered on the support, for making electric machine support solid and reliable, not yielding, it generally needs thicker metal material to be stamped to form, and like this, can cause the difficulty of punching press to increase on the one hand, production percent defective height can increase material cost on the other hand.At this kind situation, Chinese patent literature publication number CN200973037Y discloses a kind of like this motor: comprise the mounting panel that motor axis hole on master shield, the master shield, supporting bracket that the master shield inward at both ends is bent to form and supporting bracket outwards are bent to form, be provided with reinforcement along master shield edge and/or support plate edge.This kind structure is because only be provided with reinforcement at master shield and/or support plate edge, and the mounting panel edge does not have reinforcement, can cause local deformation easily, and the support of this kind structure makes motor and external member that inconvenience is installed.
The utility model content
The purpose of this utility model is intended to overcome the shortcoming of prior art, the micro-machine support that a kind of intensity is big, manufacturing is simple, cost is low is provided, and this kind micro-machine support can be used as the mounting bracket of the member of motor own, and the while is as the mounting bracket of motor and external member installation.
The technical scheme that realizes the utility model purpose is:
A kind of micro-machine support, comprise fore-stock, after-poppet, fore-stock and after-poppet are made of the supporting bracket and the mounting panel of top board, top board both sides respectively, be respectively equipped with motor axis hole on the top board, be respectively equipped with the connecting hole that fore-stock, motor and after-poppet are assembled together of mutual correspondence on the mounting panel, it is characterized in that middle part, top board edge is open and flat, top board remaining edge, support plate edge and mounting panel edge outwards are bent to form flange.These flange can improve forward and backward support integral intensity respectively, and this flange makes top board, supporting bracket, mounting panel form the integral body of a compactness, are not easy to cause local deformation or tear, thereby influence machine operation.
Described fore-stock mounting panel is provided with the installing hole with the external member assembling.Motor can carry out mount by this installing hole with cooperating of other external members.
Above-mentioned installing hole is four, and every limit mounting panel is provided with 2.
The motor axis hole both sides are respectively arranged with the motor component pilot hole on the described after-poppet top board.This motor component pilot hole can with assembled such as circuit board assemblies or carbon brush.
Be respectively arranged with louvre on the described after-poppet supported on both sides plate.
When the utility model uses, forward and backward support is fastened on the motor two ends respectively, make the motor shaft front and back ends pass motor axis hole on the forward and backward support respectively, with screw the connecting hole on the forward and backward support is connected again, fore-stock, motor and after-poppet are assembled together.When needs are installed to motor on other external members, can realize the mount of motor and other external members by the installing hole on the fore-stock mounting panel.
The beneficial effects of the utility model are: adopted the full flange formula of maximum integral body structure in the structure, make forward and backward support respectively become as a whole, effectively improve the intensity of electric machine support edge or corner, avoid yielding or fracture when intensive work, and can avoid the too thin situation about resonating of mounting panel with the complete machine generation, improve simultaneously the whole stressing conditions of electric machine support significantly, make its use also can reach same intensity than the thiner made of original product, even better, the economical with materials cost.Farthest the edge turnup structure makes the support bulk strength higher, both can be used for the motor internal assembling, also can be used for simultaneously external mounting, current collection machine internal stent and outside mounting panel are in one, manufacturing is simple, scrappage is low, assembly precision height, assembly manipulation convenience, single amount is few with material, cost is cheaper; The after-poppet supporting bracket is provided with louvre, can make the motor available ventilation, improves radiating effect, reduces the temperature of electric motor element device.

Fig. 2 is the after-poppet structural representation;
Fig. 3 is the structural representation that forward and backward support and motor are fixedly installed togather.
Embodiment
Below in conjunction with drawings and Examples embodiment of the present utility model is further described.
Referring to Fig. 1 to Fig. 2, the utility model comprises fore-stock 1, after-poppet 2, and fore-stock 1 is one-body molded by the supporting bracket 12 and the mounting panel 13 of top board 11, both sides, and same after-poppet 2 is one-body molded by the supporting bracket 22 and the mounting panel 23 of top board 21, both sides.On fore-stock 1 and the after-poppet 2, except middle part, top board 11,21 edges 111,211 is the flat configuration, the remaining edge of forward and backward support outwards turns down and forms flange 14,24, makes top board 11,21, supporting bracket 12,22 and the integral body that version 13,23 constitutes a compactness respectively is installed. Top board 11,21 middle parts of fore-stock 1 and after-poppet 2 are respectively arranged with motor axis hole 15,25.The mounting panel 13 of fore-stock 1 is provided with the connecting hole 16 with the motor assembling, and the position of corresponding connecting hole 16 also is provided with connecting hole 26 on after-poppet 2.Motor axis hole 211 both sides are respectively arranged with the electric machine assembly pilot hole 212 of assembled such as can be used for circuit board assemblies or carbon brush on the after-poppet top board 21, be respectively arranged with louvre 221 on the supporting bracket 22 of after-poppet 2 both sides, can make the motor available ventilation, improve radiating effect, reduce the temperature of electric motor element device.Respectively be provided with the installing hole 17 of 2 motors and external member assembling on the mounting panel 13 of fore-stock 1 both sides, can make motor carry out mount with external member easily by installing hole 17.
As shown in Figure 3, when the utility model uses, forward and backward support 1,2 is fastened on motor 3 two ends respectively, make the motor shaft front and back ends pass motor axis hole 15,16 on the forward and backward support 1,2 respectively, with screw 4 connecting hole on the forward and backward support 1,2 16,26 is connected again, fore-stock 1, motor 3 and after-poppet 2 are assembled together.When needs are installed to motor on other external members, can realize the mount of motor and other external members by the installing hole on the fore-stock mounting panel 13 17.
