Abstract

A chip removing device comprises a movable base, wherein a supporting rod is fixed on the base, one side of the supporting rod is fixed with a handspike with a handle, the other end of the supporting rod is fixed with a centre shaft, a bearing is sleeved on the centre shaft, an inner circle of the bearing closely matches with the centre shaft, a fixture block is nested into a bearing outer ring, and a workpiece fixing device is arranged on the fixture block. Capable of doing chip removing treatment to various gears of a similar disk shape, the chip removing device of the utility model can save labor and time, thereby raising the work efficiency.

Description

A kind of device of deburring

Technical field

The utility model relates to a kind of device of deburring, employed device during especially to the discoid object deburring of similar toothed belt wheel.

Background technology

Toothed belt wheel procedure after shaping is deburring.At present, because of no specialized apparatus, therefore, in the past always with manual type to product deburring one by one.During artificial deburring, each product is when operation, and the variation of operator's muscle power will directly influence the deburring effect of product, increase product and knock the possibility that hair is damaged.And the labour intensity of deburring is big, and efficient is low.And manual type causes the quality instability of deburring.

Summary of the invention

For the burr of the discoid object of the faster and better similar toothed belt wheel of removal, employed device when a kind of deburring is provided of the present utility model, its structure is as follows:

A kind of device of deburring, comprise mobile base, be fixed with a support bar on the base, support bar one side is fixed a push rod with handles, opposite side is fixed with an axis, is with a bearing on the axis, and bearing inner race and axis closely cooperate, bearing outer ring embeds a fixture block, and the device of a fixation workpiece is arranged on the fixture block.

More specifically, the device of described fixation workpiece can be the closely cooperate protrusion of the inner slotted eye of workpiece of a shape.

More specifically, bearing opposite side on axis increases a block, and block is made up of two cylinders that the bottom surface radius does not wait, and radius bigger its base area of that cylinder in bottom surface is more than or equal to the base area of workpiece and press close to bearing.

Used burr remover provided by the utility model, can carry out deburring to similar discoid various gears and handle, can labor savings and time, and increase work efficiency.

The specific embodiment

Now, the utility model is further described according to accompanying drawing:

As shown in Figure 1, the burr remover overall structure is as follows: fix a support bar 2 on a mobile base 1, support bar 2 one sides are fixed with a push rod with handles 3, support bar 2 opposite sides are fixed with an axis 4, be with a bearing 5 on the axis 4, bearing inner race and axis 4 closely cooperate, bearing outer ring embeds a fixture block 6, the device 7 that a fast pulley is arranged on the fixture block 6, it is the closely cooperate protrusion of belt pulley 8 inner slotted eyes 9 of a shape, therefore belt pulley 8 can closely be nested on the device 7, bearing 5 opposite sides have a block 10, block is made up of two cylinders that the bottom surface radius does not wait, and the base area of that cylinder 11 that the bottom surface radius is bigger is more than or equal to the base area of belt pulley 8.

When giving belt pulley 8 deburrings, at first start motor 12, driving discoid hairbrush 13 thus rotates, this moment, the workman can push control rod 3 make whole burr remover close to hairbrush 13, can be brushed by hairbrush 13 until the belt pulley 8 that is nested on the device 7, because axis 4 is fixed, and the inner ring and the axis 4 that are enclosed within the bearing 5 on the axis 4 closely cooperate, the outer ring of bearing 5 embeds in the fixture block 6 simultaneously, and the device 7 tight fast pulleies 8 on the fixture block 6, so when belt pulley 8 is brushed the tooth of outer ring by hairbrush 13, belt pulley 8 can be under the induced effect of hairbrush 13, with axis 4 is that rotation is done in the axle center, because the rotation effect of belt pulley 8 gets so that the tooth of its outer ring can be all by hairbrush 13 deburrings.The opposite side of bearing 5 can add a block 10; block 10 is made up of two cylinders that the bottom surface radius does not wait; the base area of that cylinder 11 that the bottom surface radius is bigger is more than or equal to the base area of belt pulley 8; when the purpose of interpolation block 10 is to prevent that the workman from operating; whole burr remover is too pressed close to hairbrush 13; hairbrush 13 can damage support bar 2; after individual block 10; because cylinder 11 base areas are more than or equal to the base area of belt pulley 8; then stopped after hairbrush 13 is too pressed close to, and then played the effect of protection support bar 2 by cylinder 11.

As pending workpiece, the utility model can also carry out deburring to similar discoid gear to be handled present embodiment, does not repeat them here with belt pulley.

Claims
