The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 to Fig. 2, grinding machine dual-purpose guard shield in angle of the present invention comprises boot main body and guard shield cover plate, and boot main body is fixedly connected with angle grinding machine main body.When it being applicable to function such as cutting when needs, guard shield cover plate and boot main body are constituted sealing guard shield shown in Figure 1; When it being applicable to function such as grinding when needs, then the guard shield cover plate being pulled down and placed on one side or be accommodated in the boot main body outside, form half guard shield and get final product.
Among the present invention, we are called executive component with the workpiece of angle grinding machine, and according to concrete duty, executive component can be emery wheel, wire wheel, saw blade etc., thereby executive component is connected and receives the driving execution work of angle grinding machine with angle grinding machine rotating shaft.
Particularly, boot main body comprises main body side plate 1 and main body installing plate 2, and the guard shield cover plate comprises cover plate side plate 3 and cover plate installing plate 4.Under installment state, the plate face of main body side plate 1 and cover plate side plate 3 is all perpendicular to angle grinding machine rotating shaft, and main body installing plate 2 and cover plate installing plate 4 are separately positioned on the outward flange of main body side plate 1 and cover plate side plate 3 and perpendicular to the side plate of correspondence.So, this just requires the shape of installing plate profile and the outward flange shape of corresponding side plate to be complementary.
As a kind of preferred, referring to Fig. 2, the plate facial contour of main body side plate 1 and cover plate side plate 3 has similitude, and all radian is identical but isocentric circular arc that radius is different and connect that the line segment of the homonymy end points of two sections circular arcs forms by two sections.In order farthest to take into account security and operability, each circular arc all approaches semicircle basically; Main body installing plate 2 is arranged on that bigger in the plate facial contour of main body side plate 1 and cover plate side plate 3 circular arc with cover plate installing plate 4 respectively.
Need to prove,, on boot main body, should be provided with installation portion 5 in order boot main body to be fixedly connected on the grinding machine main body of angle; As shown in Figure 2; Installation portion 5 is that the cross section that autonomous agent side plate 1 plate face center outwards forms is the bulge-structure of annulus, certainly, also can be other shapes or structure; This is that those skilled in the art are easy to expect, does not give unnecessary details here.
We said the front, when needs use half guard shield, the guard shield cover plate were placed on one side or also can be accommodated in the outside of boot main body.In order to realize taking in; Make angle grinding machine complete machine structure compact more; The radius of that less circular arc should be greater than radius of a circle maximum in the cross section annulus of installation portion 5 in the plate facial contour of cover plate side plate 3, and like this, the guard shield cover plate just can be accommodated in the outside of boot main body.
Through above-mentioned, we have known the basic structure of dual-purpose guard shield, to change quickly between two kinds of purposes and increase reliability in order to be implemented in, and boot main body and guard shield cover plate are provided with and cooperatively interact, the fixing position limiting structure of position each other.
Referring to Fig. 1 to Fig. 2, as a kind of preferred, position limiting structure comprises: be arranged on the limited post 6 on the main body installing plate 2 and be arranged on the spacing bayonet socket 7 on the cover plate installing plate 4.Position limiting structure can be preferably two pairs for a pair of or how right, is separately positioned on two ends of installing plate.In addition, limited post 6 can also be provided with cap away from an end of main body installing plate 2, and the radius of cap can prevent further that greater than the radius of limited post 6 remainders boot main body and guard shield cover plate from relatively moving.In actual production process, limited post 6 can adopt rivet, and is not only convenient but also reliable.
When constituting the sealing guard shield, at first boot main body and guard shield cover plate are had good positioning, then through position limiting structure; In order to prevent the structure of the factor affecting guard shields such as vibration in the course of work; Also be provided with the connector of attachment shield main body and guard shield cover plate, and the guard shield cover plate itself is formed with the mounting structure that cooperates with connector, simultaneously; The outside of boot main body also is equipped with and cooperates with connector so that itself and guard shield cover plate constitute an integral body, promptly seals the latch assembly of guard shield.
Operation for ease, connector is arranged on the main body installing plate 2, and mounting structure and latch assembly all are arranged on the cover plate installing plate 4.Mounting structure is preferably the installing hole 14 that supplies connector to pass.
Below we specify connector and the latch assembly that boot main body and guard shield cover plate are locked together:
Referring to Fig. 1 and Fig. 2, connector has contact with 8 for being fixed on through welding or other modes on the main body installing plate 2; Have contact with 8 and pass the installing hole 14 that is formed on the guard shield cover plate, latch assembly comprises the trigger piece 9 that is rotationally connected with cover plate installing plate 4, is connected and rotating hasp 10 with trigger piece 9.Hasp 10 with have contact with 8 and cooperatively interact, under the effect of trigger piece 9, realize locking or separation.Specifically, hasp 10 is buckled in has contact with on 8, with trigger piece to pulling near the direction of cover plate installing plate 4, then can with hasp 10 with have contact with 8 lockings, otherwise then both are separated.
For trigger piece 9 is rotatably connected on the guard shield cover plate, on the cover plate installing plate, be provided with the key seat 11 of band pin-and-hole, an end of trigger piece 9 is rotationally connected the axis of the parallel axes of trigger piece pin 12 grinding machine rotating shaft in the angle through trigger piece pin 12 and key seat 11 formations.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
