Detailed ways

Referring to Figures 1 to 9, the wrench grinder includes a frame 1, on which a blanking device 2 for holding a wrench 3 is arranged, and one side of the blanking device 2 is provided with a The conveying device 4 that walks the wrench 3 and transports it. The frame 1 is sequentially provided with a rough grinding device 5 and a fine grinding device 6 for grinding the wrench 3 in the direction of transportation of the conveying device 4. A control box 7 for controlling the actions of each device is also provided. During processing, the blank parts of the wrench 3 are stacked and placed in the blanking device 2, and then the conveying device 4 takes a wrench 3 from the blanking device 2 in sequence, Then send to coarse grinding device 5 and fine grinding device 6 places successively to carry out rough grinding and fine grinding, after grinding is finished, send to finished product area at last, because the present invention is by arranging blanking device 2, delivery device 4 on frame 1 , coarse grinding device 5, fine grinding device 6 and control box 7, control the operation of each device through the control box 7, realize fully automatic grinding wrench 3, abandon the previous manual grinding, and greatly improve the grinding efficiency.

In the present invention, the blanking device 2 includes two guide grooves 21 vertically arranged on the frame 1 and allowing the wrench 3 to be placed between them, and the two guide grooves 21 are preferentially added to the wrench 3 The arc-shaped grooves corresponding to the two ends, when a plurality of wrenches 3 are placed, the plurality of wrenches 3 overlap together and are located between the two guide grooves 21 and the two ends of the wrench 3 are respectively connected to the two guide grooves 21 The inner walls of the two guide grooves 21 are in sliding contact, that is, the two ends of the wrench 3 are respectively abutted against the inner walls of the two guide grooves 21 and can slide up and down between the two guide grooves 21. 22 and a blanking cylinder 23, the piston rod of the support cylinder 22 is connected with a support block 24 for supporting the wrench 3, and the piston rod of the blanking cylinder 23 is connected with a blanking block 25 capable of supporting the wrench 3 , the horizontal height of the supporting block 24 is higher than the horizontal height of the blanking block 25 and the height difference between them is the thickness of a wrench 3. Under normal circumstances, the piston of the blanking cylinder 23 and the supporting cylinder 22 The rods are all in the extended state. At this time, the blanking block 25 supports the bottom wrench 3, while the support block 24 supports the bottom second wrench 3. When blanking, the piston rod of the blanking cylinder 23 Drive the blanking block 25 to shrink back. At this time, the wrench 3 at the bottom layer falls down due to loss of support, so that it is carried by the conveying device 4 and takes away a wrench 3. After that, the blanking cylinder 23 drives the blanking block 25 stretches out again, and the support cylinder 22 drives the support block 24 to shrink back, so the wrench 3 supported on the support block 24 falls down and is supported on the blanking block 25, and then the support block 24 is driven by the support cylinder 22 Stretch out again and insert into the stacked wrench 3 and support the penultimate wrench 3 at the bottom, and then the blanking cylinder 23 drives the blanking block 25 to shrink back again, so as to perform blanking, and the cycle continues blanking like this.

Further, the conveying device 4 includes a main sprocket 41 and a secondary sprocket 42 arranged on the frame 1 and a chain 43 sleeved on the main sprocket 41 and the secondary sprocket 42, and the outer peripheral wall of the chain 43 is sequentially arranged There are a plurality of hooks 44 that can hook the wrench 3, and the frame 1 is also provided with a conveying motor 45 for driving the main sprocket 41 to rotate. When the conveying motor 45 drives the chain 43 to rotate, the hook 44 moves together with the chain 43. When the hook 44 moved to the bottom of the blanking device 2, the blanking cylinder 23 acted to perform blanking. During the process of the wrench 3 falling down, the end of the wrench 3 provided with a circular ring was just inserted into the hook 44 to realize the removal. Material, after taking material, chain 43 drives wrench 3 to continue to move forward again.

At the same time, the rough grinding device 5 includes a plurality of guide wheels 51 and two groups of grinding heads 52 respectively located on both sides of the conveying device 4 and capable of allowing the wrench 3 to pass between them. The outer surface of the guide wheel 51 is provided with a grinding belt 53 for grinding the wrench 3, and the frame 1 is also provided with a grinding motor 54 for driving the guide wheel 51 to rotate and driving the grinding belt 53 to rotate. The group of grinding heads 52 are respectively provided with a guide rod 55 and a screw mandrel 56, the grinding head 52 is movably mounted on the guide rod 55 and driven to move up and down by the screw mandrel 56, and the screw mandrel 56 is connected with a lifting motor 57 that drives its rotation, The lifting motor 57 is fixedly installed on the frame 1. When the hook 44 drives the wrench 3 to come between the two grinding heads 52, the two grinding heads 52 move towards each other and close to and clamp the two surfaces of the wrench 3, and then The grinding belt 53 rotates and grinds the wrench 3. While grinding the two surfaces of the wrench 3, the lifting motor 57 also operates, and the grinding head 52 is driven by the screw mandrel 56 to move the grinding wrench 3 up and down. After the rough grinding is completed, Hook 44 drives wrench 3 and continues to move forward.

Further, the fine grinding device 6 includes a plurality of fine guide wheels 61 and two groups of fine grinding heads 62 respectively located on both sides of the conveying device 4 and capable of allowing the wrench 3 to pass between them. The outer surface of the head 62 and the fine guide wheel 61 is sheathed with a fine grinding belt 63 for grinding the wrench 3, and the frame 1 is also provided with a fine grinding motor for driving the fine guide wheel 61 to rotate and driving the fine grinding belt 63 to rotate 64. At the same time, the corresponding two groups of fine grinding heads 62 on the frame 1 are respectively provided with fine guide rods 65 and fine screw rods 66. Move, described fine screw mandrel 66 is connected with the fine lifting motor 67 that drives its rotation, and described fine lifting motor 67 is fixedly installed on the frame 1, and the working principle of rough grinding device 5 is the same, and hook 44 drives wrench 3 to come Between the two fine grinding heads 62, the two fine grinding heads 62 clamp the two surfaces of the wrench 3 and grind them. During the grinding process, the fine lifting motor 67 drives the fine grinding head 62 through the fine screw rod 66. Move and polish the two surfaces of the wrench 3 downwards, and the finished product can be obtained after the fine grinding is completed, and finally the hook 44 sends the finished product to the finished product area and blanks.

The above descriptions are only the preferred implementation modes of the present invention, as long as the technical solutions to achieve the purpose of the present invention by basically the same means fall within the scope of protection of the present invention.
