Equipped with multiple sanding blocks 7 for along left and right to horizontal positioned dumbbell 20.Sanding block 7 is the U-shaped seat of upward opening, U-shaped polishing
It is offered respectively on the side plate of left and right two of seat 7 and puts two ends of dumbbell for card and protrude outward the side to be polished of dumbbell
Bayonet.
When polishing, the side end face to be polished of dumbbell 20, which needs to extend out to from close to the bayonet of side burrs workpiece polishing mechanism, to be beaten
The outside of mill seat 7 can be just polished to, and therefore, the length of the sanding block 7 in the utility model is slightly less than its dumbbell to be placed
The side of left and right two of 20 length, such dumbbell 20 can be protruded outward from bayonet.Dumbbell 20 cannot rotate in bayonet,
So that upside flash workpiece polishing mechanism polishes to the upper surface of dumbbell 20.
The distance between side burrs workpiece polishing mechanism and upside flash workpiece polishing mechanism of the utility model are equal to adjacent ground
N times of 7 spacing of seat.Side burrs workpiece polishing mechanism be provided in rack 1 left and right two sets, respectively to the left and right side of dumbbell 20 into
Row polishing;Upside flash workpiece polishing mechanism is provided with more sets along conveying direction in rack 1, with different to 20 upside of dumbbell respectively
The flash at position carries out grinding process.
Rack 1 include the two rows of columns in left and right and along front and back to the supporting plate 25 for being installed in two rows of column top centers position,
Former and later two shafts 2, driven chain are provided with by the rotation of a pair of bearing 21 respectively on two rows of columns of 25 front and rear sides of supporting plate
Wheel 4 and drive sprocket 26 are installed in the middle position of former and later two shafts 2 respectively, and the upper half horizontal feed part of chain 3 is located at
On supporting plate 25.There are gaps or chain 3 to tow in supporting plate 25 between chain 3 and supporting plate 25, and supporting plate 25 makes using upper
When flash polishing motor 15 in side polishes to the dumbbell 20 in sanding block 7, supporting plate 25 can hold polishing in the vertical direction
Seat 7.
A pair of of driven sprocket 4 and a pair of of drive sprocket 26, two driven sprockets 4 are installed in former and later two shafts 2 respectively
Parallel winded has the chain 3 of left and right two operated synchronously between two drive sprockets 26;On the opposite flank of two chains 3
It is fixed with multipair pedestal 5, a backing plate 6 is respectively fixed on each pair of pedestal 5, a sanding block 7 is respectively installed on each backing plate 6.
Backing plate 6 is fixedly connected by bolt with a pair of of pedestal 5, and two positioning inserting columns and a positioning are additionally provided on backing plate 6
Screw hole;The positioning jack for positioning inserting column insertion is provided on the bottom plate of sanding block 7 accordingly and insertion positioning screw hole can be cooperated
In fastening bolt.The sanding block 7 of the utility model is removable to be arranged on backing plate 6, in order to according to the size of dumbbell 20
Replace various sizes of sanding block 7.
The left and right sides positioned at chain 3 is additionally provided in rack 1, spacing is adjustable and for protecting sanding block 7 and mute thereon
Bell 20 shields and sustain mechanism;Shielding and sustain mechanism includes to a pair of of strip grip block 8 disposed in parallel and being installed in clamping along front and back
