[0018] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0019] See also Figures 1 to 6The utility model provides a pick-up and placement device for fine grinding of the outer circle of a guide column, which comprises two left-right symmetrical support plates 1 and a slide rail 7 transversely arranged above the support plates 1. Two conveying chains 3 driven by a first motor 2 and distributed left and right are rotatably arranged between the support plates 1. A conveyor belt 13 is arranged on the right side of the conveying chain 3. A driving gear 14 and a driven gear 15 are respectively connected to the conveying chain 3 and the conveyor belt 13. The driving gear 14 and the transmission gear 15 are meshed with each other. Through the driving gear and the transmission gear, the conveying chain conveys the unfinely ground guide column forward, and the conveyor belt conveys the finely ground guide column backward. The inner side of the conveying chain 3 is evenly distributed with a frame block 4 for erecting the guide column, and a stabilizing plate 6 is vertically arranged at the front end of the two support plates 1. A lifting assembly 5 for lifting the front guide column is arranged at the stabilizing plate 6. A screw driven by a second motor 9 is transversely and rotatably arranged on the slide rail 7. A slider 8 screwed to the screw is slidably arranged at the slide rail 7 for left and right movement. The front end of the slider 8 is provided with two grabbing assemblies distributed left and right. The first motor drives the two conveyor chains to transport the guide pillars forward in sequence. When the front guide pillar is above the lifting assembly, the lifting assembly lifts the front guide pillar to ensure the accurate position of the lifted guide pillar. The grabbing assembly on the left grabs the lifted guide pillar upwards, and the second motor drives the slider to move the two grabbing assemblies to the right through the screw. The grabbing assembly on the right grabs the guide pillar that has been finely ground on the cylindrical grinder upwards, and the grabbing assembly on the left lowers the guide pillar onto the cylindrical grinder. Then the second motor drives the slider to move the two grabbing assemblies to the left and reset through the screw, and the grabbing assembly on the right lowers the finely ground guide pillar onto the conveyor belt.

[0020] The grab assembly includes a second lifting cylinder 10 disposed downward at the front end of the slider 8, a clamping cylinder 11 is disposed at the end of the piston rod of the second lifting cylinder 10, the left clamping claw of the clamping claw cylinder 11 is in an inverted triangle shape and a cylinder is disposed transversely at its lower end, and the right clamping claw of the clamping claw cylinder 11 is in a square shape and a limit block is disposed at its lower end. The cylinder can be inserted into the screw hole of the guide column, and the limit block can lift the guide column seat of the guide column.

[0021] The lifting assembly 5 includes a first lifting cylinder 5.1 which is upwardly arranged on the stabilizing plate 6. A connecting plate 5.2 is horizontally arranged at the end of the piston rod of the first lifting cylinder 5.1. Lifting members 5.3 are adjustable on both sides of the upper end of the connecting plate 5.2. The first lifting cylinder drives the connecting plate to lift the lifting member. The lifting member lifts the frontmost guide post to separate from the frame block, thereby ensuring the accurate position of the lifted guide post. After grabbing the lifted guide post, the first lifting cylinder drives the connecting plate to lower and reset the lifting member.

[0022] The lifting member 5.3 is composed of a lifting portion on the upper side connected to a bent connecting portion on the lower side, and a V-shaped frame groove is provided on the upper side of the rear end of the lifting portion.

[0023] A bending plate is arranged in the middle of the upper end of the connecting plate 5.2, and a sensor 12 is arranged at the upper end of the bending plate facing backward. The sensor senses the frontmost guide post on the frame block, and the first lifting cylinder drives the lifting member to rise, and the lifting member lifts the frontmost guide post to separate from the frame block, thereby ensuring the accurate position of the lifted guide post, and the two clamping claws of the left clamping claw cylinder clamp the guide post and move it to the cylindrical fine grinder and put it down.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
