Abstract

The utility model discloses a wheel machining drilling machine comprising a drilling machine body used for drilling a hole in a center of a wheel and an operation handle disposed on the drilling machine body. The laborsaving sleeve is fixedly sleeved on the operation handle by a pin shaft. The pin shaft passes through the laborsaving sleeve and the operation handle, and the pin shaft is in the shape of a cone. The pin shaft is inclinedly arranged, and the conicity of the pin shaft decreased gradually along the operation handle facing the operation direction. The laborsaving sleeve is arranged at an acute angle relative to the side surface of the drilling machine body, and the acute angle is 30 degrees. The wheel machining drilling machine provided in the utility model has advantages of labor saving, practicability, and ability of reducing the labor intensity of operators by the pre-drilling in the center of the wheel.

Description

Wheel processing drilling machine

Technical field

The utility model relates to wheel manufacturing technology field, is specifically related to a kind of rapid operation wheel processing easily drilling machine.

Background technology

After wheel cast went out blank, the allowance when reducing follow-up machined preface machining center hole need carry out prebored hole according to the final centre bore of product, and great majority all are through on drilling machine, casting the centre-drilling hole of blank at present.For the control of general drilling machine, well-known, all be to control the amount of feeding of drill bit through shaking Handl eof drill press, because the drilling depth of wheel blanks is shallow, general handle 2/3 process of rotating that only needs can be accomplished the boring action, that is to say and can accomplish prebored hole.Existing then Handl eof drill press length is shorter, the effort that operates, and labour intensity is big, inefficiency; And the operating grip on the general drilling machine all is compact the setting on drilling machine, promptly is that operating grip all is the parallel or approximate side that is parallel to drilling machine.

Summary of the invention

To above-mentioned weak point of the prior art, the utility model aims to provide a kind of wheel processing drilling machine, and it is laborsaving to operate, and has reduced operator's labour intensity.

The technical scheme of the utility model: a kind of wheel processing drilling machine, be included as wheel center boring the drilling machine body and on operating grip, on said operating grip, be provided with a laborsaving sleeve, this laborsaving sleeve fixed cover is located on this operating grip.

Said laborsaving sleeve and said operating grip are fixed through bearing pin, and this bearing pin is on said laborsaving sleeve and said operating grip.

Said bearing pin is cone, and this bearing pin is obliquely installed, and it successively decreases along said operating grip forward traffic direction tapering.

The side of the said drilling machine body of said laborsaving sleeve is the acute angle angle.

Said acute angle angle is 30 °.

Through on the operating grip of drilling machine, setting up the sleeve of the effect that extends together, make the operator when holing for wheel center, hold this sleeve and exert all one's strength, can release according to lever principle, the utility model is more laborsaving, has reduced operator's labour intensity.Owing to all be compact the setting between general drilling machine and the operating grip, therefore, the side of said laborsaving sleeve and drilling machine body is the setting of acute angle angle, avoid other parts on laborsaving sleeve and the drilling machine body to interfere, the while is the handled easily personnel operation also; In order to prevent the operator after putting down sleeve, during the operating grip recovery location, sleeve is unstable and deviate from, and the utility model is fixedly connected with said operating grip sleeve through bearing pin.

The laborsaving practicality of the utility model has reduced the operator at the labour intensity for wheel center boring, has improved operating efficiency.

Fig. 4 is the front view of another form of Fig. 1.

The specific embodiment

Come further explain the utility model below in conjunction with specific embodiment and accompanying drawing.

Referring to Fig. 1 and Fig. 2, described wheel processing drilling machine, its be included as wheel center boring drilling machine body 10 and on operating grip 20, on said operating grip 20, be provided with a laborsaving sleeve 30, these laborsaving sleeve 30 fixed covers are located on this operating grip 20.The operator is when holing for wheel center, and this laborsaving sleeve 30 of grasped makes operating grip 20 rotate, and that is to say; The extended length of said operating grip 20, through lever principle, moment is elongated; The power that the operator need use has just reduced, and has reduced operator's labour intensity.

Laborsaving sleeve 30 in the utility model is a steel pipe; This laborsaving sleeve 30 can be set on the operating grip 20 on the said drilling machine body 10; Preferably; The internal diameter of said laborsaving sleeve 30 matches with the external diameter of said operating grip 20, promptly be that laborsaving sleeve 30 is set on the operating grip 20, and fit system is an interference fits.

Preferably, said laborsaving sleeve 30 is fixed through bearing pin 50 with said operating grip 20, and this bearing pin 50 is on said laborsaving sleeve 30 and said operating grip 20.Further, said bearing pin 50 is cone, and this bearing pin 50 is obliquely installed, and it successively decreases along said operating grip 20 forward traffic direction taperings.The effect of said bearing pin 50 mainly be prevent operating grip 20 during in when work or in recovery location laborsaving sleeve 30 break away from said operating grip 20.Because after being fixedly connected through this bearing pin 50 between said laborsaving sleeve 30 and the said operating grip 20, the operator just needn't worry that laborsaving sleeve 30 comes off, and gets final product the relieved continuous bore operation that carry out, and enhances productivity.

Further, said laborsaving sleeve 30 is the acute angle angle with the side of said drilling machine body 10.Just, referring to Fig. 3 and Fig. 4, said laborsaving sleeve 30 acutangulates the angle setting away from operating grip 20 ends and operating grip 20, and laborsaving sleeve 30 away from operating grip 20 ends away from drilling machine body 10.Such as, laborsaving sleeve 30 is a straight line away from the end of operating grip 20, the side of itself and operating grip 20 or drilling machine body 10 is the acute angle angle, sees Fig. 3; Perhaps said laborsaving sleeve 30 is an arc away from the end of operating grip 20, and is same, is the acute angle angle between the side of itself and said operating grip 20 or drilling machine body 10.Preferred in the present embodiment, the angle between the side of said laborsaving sleeve 30 and drilling machine body 10 is 30 °.

The above is merely the detailed description of the utility model preferred embodiment and graphic, is not to be used for limiting the utility model, and the embodiment or the approximate construction of all similar variations of doing according to the creation spirit of the utility model all should be contained among the utility model.
