Referring to fig. 1 to 5, the present invention provides an embodiment: the utility model provides a grinding device of construction steel bar, includes casing 1, grinding wheel 2, motor 9, slider 11, threaded rod 12, gag lever post 16 and gyro wheel 17, and through-hole 5 has all been seted up to 1 both sides outer wall of casing, and the welding of 1 lower surface four corners of casing has support 10. Connecting rod 15 of symmetric distribution is all installed to 1 both sides inner wall of casing, and connecting rod 15 all welds gag lever post 16 about through-hole 5 symmetric distribution, connecting rod 15 one end, and 16 inside slidable mounting of gag lever posts have axis of rotation 6. The outer wall of the rotating shaft 6 is elastically connected with the inner wall of the limiting rod 16 through a spring 7, and one end of the rotating shaft 6 is rotatably provided with a roller 17. The roller 17 slides in the limiting rod 16 through the rotating shaft 6, and the spring 7 enables the roller 17 to move up and down through elasticity, so that the roller 17 is elastically attached to the outer wall of the reinforcing steel bar. Two gyro wheels 17 are corresponding with 2, and when the staff put into the reinforcing bar from through-hole 5, the reinforcing bar during gyro wheel 17, in the gag lever post 16 with 16 inner wall elastic connection's of gag lever post spring 7 area the axis of rotation 6 shrink of spring 7 is being connected to the outer wall, and install gyro wheel 17 at 6 one ends of axis of rotation and follow axis of rotation 6 and remove, until gyro wheel 17 and the nimble laminating of reinforcing bar outer wall, reach and carry out spacing effect to the reinforcing bar. Thereby being convenient for people to control the reinforcing steel bars not to deviate from the polishing range of the polishing sheet 4.

The inner wall of the upper end and the inner wall of the lower end of the shell 1 are respectively provided with a first sliding chute 3 and a second sliding chute 13, and sliding blocks 11 are movably mounted in the first sliding chute 3 and the second sliding chute 13. The lengths of the first sliding chute 3 and the second sliding chute 13 are consistent, and the sliding blocks 11 in the first sliding chute 3 and the second sliding chute 13 can synchronously move to the bottom end of one side of the first sliding chute 3 and the bottom end of the second sliding chute 13, which is different from the rotating wheel 19. The base 14 is fixed on the upper surface of the sliding block 11 in the second sliding groove 13, the motor 9 is fixed on the upper surface of the base 14, the motor 9 is Y80M1-2 type, and the motor 9 of the type has the advantages of small size and light weight and can meet the actual use requirement. A fixed block 21 is arranged at one side of the lower end of the shell 1, which is different from the inner wall of the second chute 13. Fixed block 21 upper surface mounting has motor 9, and two motor 9 upper surfaces all rotate and install motor shaft 8, and motor shaft 8 outer wall all cup joints grinding wheel 2, and grinding wheel 2 embedding is fixed with the piece 4 of polishing, and the 11 lower surfaces of slider inside 1 casing are fixed to motor shaft 8 upper end of the motor 9 of 14 upper end installations of base. The reinforcing bar continues forward through gyro wheel 17, and the wheel 2 of polishing of second spout 13 one side is driven by slider 11 in the casing 1 and is close to the wheel 2 of polishing of being different from second spout 13 one side, and two wheel 2 of polishing are from both sides reinforcing bar of polishing to the people of being convenient for polish to the reinforcing bar difference side.

The outer wall of one side of the shell 1 is embedded with a threaded sleeve 18, and the threaded rod 12 is rotatably arranged in the threaded sleeve 18 through threads. The welding of threaded rod 12 one end has the wheel 19 that rotates, and rotates the wheel 19 and deviate from the welding of threaded rod 12 one side outer wall and have a handle 20, and threaded rod 12 deviates from the welding of wheel 19 one end and has a movable block 22, and movable block 22 rotates and installs inside base 14 one side. Before the reinforcing bar gets into the scope of polishing of wheel 2, the staff rotates handle 20, handle 20 area is rotated wheel 19 and is made threaded rod 12 forward in 18 internal rotations of thread bush, the messenger connects threaded rod 12 and deviates from movable block 22 of rotating wheel 19 one end and at the inside rotation of base 14 one side and impel the slider 11 that the base 14 lower surface is connected, thereby make base 14 upper surface upper end motor 9 drive polish piece 4 and remove to another polish piece 4, can control the distance between polish piece 4 in a flexible way, thereby the reinforcing bar of the different diameters of being convenient for people to polish.

The working principle is as follows: the reinforcing steel bar enters through the through hole 5, and when the reinforcing steel bar passes through the roller 17 on one side of the through hole 5, the spring 7 in the limiting rod 16 drives the rotating shaft 6 to contract so that the roller 17 reaches a position for clamping the reinforcing steel bar. The reinforcing steel bar is clamped by the roller 17 and then continues to move forwards, before the reinforcing steel bar enters the grinding range of the grinding wheel 2, the handle 20 is rotated, and the handle 20 drives the rotating wheel 19 to enable the threaded rod 12 to rotate forwards in the threaded sleeve 18. The movable block 22 welded at one end of the threaded rod 12, which is far away from the rotating wheel 19, rotates inside one side of the base 14 and pushes the sliding block 11 connected with the lower surface of the base 14, so that the motor 9 at the upper end of the upper surface of the base 14 drives the polishing sheet 4 to approach to another polishing sheet 4, and the two polishing sheets 4 polish the steel bars from two sides. The rebar after sanding leaves the sander from the through-hole 5 through the roller 17 on the other side.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
