In order to ensure that the flatness of metal products meets specific standards and requirements, it is usually necessary to use special testing equipment to test the flatness of metal products.

[0003] When the existing flatness detection device for metal product processing detects the flatness of the surface of plate-shaped metal products, since the metal products are relatively long, when they move past the bottom of the laser detector, the two sides of the metal products are easily lifted up during the pushing process, which affects the laser detector's detection of the flatness of the metal product surface. Therefore, improvement is needed. Summary of the invention

A moving block is provided at the central position of the top of the top frame between the two groups of limiting side plates, and mounting frames are symmetrically provided on both sides of the top of the top frame. A concave frame is fixedly installed on one side of the top of the top frame, and a laser detector is provided on the top of the concave frame. Two groups of electric push rods are fixedly installed on the top of the top frame on both sides of the concave frame, and a top plate is fixedly installed on the top ends of four groups of electric push rods located on the same side of the concave frame.

[0006] As a further solution of the present invention: rectangular grooves 1 are symmetrically provided on both sides of the top frame, rectangular groove 2 is provided on the top of the top frame between the two groups of rectangular grooves 1, limiting sliding grooves are symmetrically provided on both sides of the inner wall of the rectangular groove 2, a moving screw is rotatably installed between the two ends of the rectangular groove 2, and one end of the moving screw passes through the top frame and is fixedly installed with a bevel gear 1, and a moving block is slidably connected to the surface of the moving screw located inside the rectangular groove 2.

[0007] As a further solution of the present invention: a rotating motor is fixedly installed at the central position of one side of the base, a bevel gear 2 is fixedly installed at the output end of the rotating motor, and the bevel gear 2 is meshed with the bevel gear 1.

[0008] As a further solution of the present invention: a push block is fixedly installed on one side of the top of the moving block, and limiting rollers are symmetrically fixedly installed on both sides of the moving block, and the positions of the limiting rollers correspond to those of the limiting slide grooves.

[0009] As a further solution of the present invention: a plurality of groups of mounting rods are fixedly installed at equal intervals inside the mounting frame, and movable rollers are rotatably installed on the surfaces of the mounting rods.

[0010] As a further solution of the present invention: a clamping connecting plate is provided on the top of the top plate, six groups of clamping rods are fixedly installed on the bottom of the clamping connecting plate, and the bottom ends of the six groups of clamping rods pass through the top plate and are fixedly installed with a clamping frame, a clamping spring is provided on the surface of the clamping rod between the top plate and the clamping frame, two groups of mounting columns are fixedly installed on the bottom of the clamping frame, and a clamping roller is rotatably installed on the surface of the mounting column.

[0011] A method for using a flatness detection device for metal product processing, the method comprising the following steps:

[0012] The rotating motor is controlled to reverse and drive the moving screw to rotate in the opposite direction, so that the moving block moves to the end of the second rectangular groove away from the laser detector, and the plate-shaped metal product is placed horizontally on the top of the two sets of mounting frames, so that the bottom of the metal product is in close contact with the surface of the moving roller, and at the same time, one side of the metal product is in close contact with the push block, and the electric push rod is controlled to extend to drive the top plate to move up on the top of the top frame, so that the pressing roller is away from the top of the top frame, and the rotating motor is controlled to rotate forward, and the moving screw is controlled to rotate forward synchronously under the meshing of the bevel gear 1 and the bevel gear 2, so that the moving block moves in the direction away from the rotating motor inside the second rectangular groove, and drives the push block to push the metal product to move on the top of the moving roller, and at the same time, the moving roller rolls on the bottom of the metal product, so as to reduce the friction of the metal product when it moves on the top of the top frame and the top of the mounting frame;

[0013] When the edge of the metal product is placed on the bottom of the pressing roller, the rotating motor is stopped, the electric push rod is controlled to shrink, the top plate is driven to move down so that the pressing frame is close to the top of the top frame, and the pressing roller is pressed against the top of the metal product. Under the rebound action of the pressing spring, the metal product is pressed against the top of the moving roller, and the rotating motor is controlled to continue to rotate forward, so that the moving block drives the pushing block to push the metal product through the bottom of the laser detector, so that the laser beam emitted by the laser detector detects the flatness of the surface of the metal product. The metal product passes through one side of the laser detector and rests on the bottom of another set of pressing rollers, so that the pressing rollers on both sides of the laser detector can press and fix the metal product, ensuring that the metal product will not be lifted when moving at the bottom of the laser detector, until the moving block moves to the side away from the rotating motor in the second rectangular groove, so that the pushing block can push the metal product out of the top frame. After the metal product is pushed out of the top frame, the rotating motor is controlled to reverse, drive the moving screw to reverse, so that the moving block on the surface of the moving screw moves in the opposite direction close to the rotating motor in the second rectangular groove, and repeat to place another group of metal products on the top of the top frame for flatness detection.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, a moving roller, an electric push rod, a clamping spring and a clamping roller are provided. After a plate-like metal product is placed on the top of the moving roller, the metal product is pushed toward the bottom of the laser detector, and the electric push rod is controlled to extend so that the top plate rises and drives the clamping roller away from the top frame. After the edge of the metal product is pushed to rest on the bottom of the clamping roller, the electric push rod is controlled to contract and drives the top plate to move downward until the clamping roller is pressed against the top of the metal product, and the electric push rod continues to contract, and the compression and deformation of the clamping spring between the clamping frame and the top plate are performed. Under the rebound action of the clamping spring, the clamping roller is pressed against the top of the metal product, and the metal product is controlled to move between the moving roller and the clamping roller through the bottom of the laser detector to ensure that when the metal product moves at the bottom of the laser detector for flatness detection, the two ends of the metal product will not lift up and affect the detection result.

[0016] 2. In the present invention, a rotating motor, bevel gear one, bevel gear two, a moving screw, a moving block and a pushing block are arranged. When the moving block is located at one end of the rectangular groove two away from the laser detector, the plate-like metal product is placed on the top of the moving roller of the two sets of mounting frames, and one side of the metal product is pressed against the surface of the pushing block. The rotating motor is controlled to rotate. Under the meshing of bevel gear one and bevel gear two, the moving screw is controlled to rotate synchronously, so that the moving block moves on the surface of the moving screw. The pushing block is controlled to push the metal product to move at a uniform speed on the top of the moving roller through the bottom of the laser detector, ensuring that when the metal product moves at the bottom of the laser detector, the metal product will not be pushed manually, resulting in the metal product moving too fast or too slow at the bottom of the laser detector, affecting the laser detector's detection of the surface flatness of the metal product.

DETAILED DESCRIPTION

[0024] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1-6 As shown, the present invention provides a technical solution: a flatness detection device for metal product processing, comprising a top frame 1, and rectangular grooves 101 are symmetrically provided on both sides of the top frame 1. Due to the rectangular grooves 101, the mounting frame 5 is fixed inside the rectangular grooves 101 to ensure that the mounting frame 5 will not be offset when it is fixed on the top of the top frame 1;

[0026] A rectangular groove 2 102 is provided at the top of the top frame 1 between the two groups of rectangular grooves 1 101, and limiting sliding grooves 103 are symmetrically provided on both sides of the inner wall of the rectangular groove 2 102. A moving screw 104 is rotatably installed between the two ends of the rectangular groove 2 102, and one end of the moving screw 104 passes through the top frame 1 and is fixedly installed with a bevel gear 105. The surface of the moving screw 104 located inside the rectangular groove 2 102 is slidably connected with a moving block 4. By providing the moving screw 104, the moving screw 104 is controlled to rotate inside the rectangular groove 2 102, so that the moving block 4 moves on the surface of the moving screw 104, thereby controlling the position of the moving block 4 inside the rectangular groove 2 102.

[0027] A base 2 is fixedly installed at the bottom of the top frame 1, and a rotating motor 201 is fixedly installed at the central position of one side of the base 2. A bevel gear 202 is fixedly installed at the output end of the rotating motor 201, and the bevel gear 202 is meshed with the bevel gear 1 105. Because the bevel gear 105 and the bevel gear 202 are provided, the rotating motor 201 is controlled to rotate forward and reverse, so that the bevel gear 202 transmits the rotation of the rotating motor 201 to the moving screw 104 through the bevel gear 105, thereby controlling the moving screw 104 to rotate forward and reverse inside the rectangular groove 102, so that the moving block 4 reciprocates on the surface of the moving screw 104.

[0028] The two sides of the top frame 1 are symmetrically fixed with limit side plates 3. Due to the limit side plates 3, the metal product is placed on the top of the top frame 1 between the two sets of limit side plates 3 to ensure that the metal product will not slide off the two sides of the top frame 1.

[0029] A moving block 4 is provided at the top of the top frame 1 at the central position between the two sets of limiting side plates 3, and a push block 401 is fixedly installed on one side of the top of the moving block 4. By providing the push block 401, when the moving block 4 moves inside the rectangular groove 102, the push block 401 is driven to move on the top of the top frame 1, so that the push block 401 can push the metal product to move on the top of the top frame 1;

[0030] The limiting rollers 402 are symmetrically fixedly installed on both sides of the moving block 4, and the position of the limiting rollers 402 corresponds to the limiting slide groove 103. Because the limiting slide groove 103 and the limiting rollers 402 are provided, when the moving block 4 moves inside the rectangular groove 102, the limiting rollers 402 are driven to roll inside the corresponding limiting slide groove 103, thereby ensuring that the moving block 4 will not tilt or deflect when moving on the surface of the moving screw 104.

[0031] Mounting frames 5 are symmetrically arranged on both sides of the top of the top frame 1, and multiple groups of mounting rods 501 are fixedly installed at equal intervals inside the mounting frames 5. Moving rollers 502 are rotatably installed on the surfaces of the mounting rods 501. By providing the moving rollers 502, when the plate-like metal products are pushed on the top of the moving rollers 502, the moving rollers 502 roll on the bottom of the metal products, thereby reducing the friction of the metal products when they move on the top of the mounting frames 5.

[0032] A concave frame 6 is fixedly installed on one side of the top of the top frame 1, and a laser detector 7 is provided on the top of the concave frame 6. Because the laser detector 7 is provided, the laser detector 7 emits laser light to illuminate the surface of the metal product, thereby detecting the flatness of the surface of the metal product;

[0033] Two groups of electric push rods 8 are fixedly installed on both sides of the concave frame 6 at the top of the top frame 1, and a top plate 9 is fixedly installed on the top of the four groups of electric push rods 8 located on the same side of the concave frame 6. By providing the electric push rods 8, the four groups of electric push rods 8 on both sides of the top plate 9 are controlled to extend and retract synchronously, so that the top plate 9 can be smoothly raised and lowered on the top of the top frame 1, avoiding the top plate 9 from tilting and deflecting during the lifting process of the top of the top frame 1.

[0034] A pressing connecting plate 901 is provided on the top of the top plate 9. Due to the pressing connecting plate 901, when the pressing frame 903 lifts the pressing rod 902 to move up and down on the top of the top plate 9, the pressing connecting plate 901 can ensure that the six groups of pressing rods 902 on the surface of the top plate 9 move synchronously, thereby preventing the pressing frame 903 from tilting and deflecting during the up and down movement, which affects the uniform force applied by the pressing roller 906 when pressing and fixing the surface of the metal product;

[0035] Six groups of clamping rods 902 are fixedly installed at the bottom of the clamping connecting plate 901, and the bottom ends of the six groups of clamping rods 902 pass through the top plate 9 to be fixedly installed with a clamping frame 903. A clamping spring 904 is provided on the surface of the clamping rod 902 between the top plate 9 and the clamping frame 903. By providing the clamping spring 904, the clamping roller 906 is pressed against the surface of the metal product under the rebound action of the clamping spring 904. When the clamping roller 906 contacts the protrusions or depressions on the surface of the metal product, the clamping roller 906 can move up and down on the top of the metal product, ensuring that the clamping roller 906 will not block the movement of the metal product while clamping and fixing the metal product.

[0036] Two sets of mounting columns 905 are fixedly installed at the bottom of the pressing frame 903, and a pressing roller 906 is rotatably installed on the surface of the mounting column 905. Due to the presence of the pressing roller 906, when the metal product moves against the bottom of the pressing roller 906, the pressing roller 906 rolls on the top of the metal product, thereby reducing the friction of the metal product when it moves at the bottom of the pressing frame 903.

[0037] A method for using a flatness detection device for metal product processing, the method comprising the following steps:

[0038] The rotating motor 201 is controlled to reverse and drive the moving screw 104 to rotate in the opposite direction, so that the moving block 4 moves to the end of the rectangular groove 2 102 away from the laser detector 7, and the plate-shaped metal product is placed horizontally on the top of the two sets of mounting frames 5, so that the bottom of the metal product is in close contact with the surface of the moving roller 502, and at the same time, one side of the metal product is in close contact with the push block 401, and the electric push rod 8 is controlled to extend and drive the top plate 9 to move up on the top of the top frame 1, so that the pressing roller 906 is away from the top of the top frame 1, and the rotating motor 201 is controlled to rotate forward, and the moving screw 104 is controlled to rotate forward synchronously under the meshing of the bevel gear 105 and the bevel gear 202, so that the moving block 4 moves in the rectangular groove 2 102 in the direction away from the rotating motor 201, and drives the push block 401 to push the metal product to move on the top of the moving roller 502, and at the same time, the moving roller 502 rolls on the bottom of the metal product, so as to reduce the friction of the metal product when it moves on the top of the top frame 1 and the mounting frame 5;

[0039] When the edge of the metal product rests on the bottom of the pressing roller 906, the rotating motor 201 is stopped, the electric push rod 8 is controlled to shrink, and the top plate 9 is driven to move downward so that the pressing frame 903 is close to the top of the top frame 1, so that the pressing roller 906 is close to the top of the metal product, and the metal product is pressed against the top of the moving roller 502 under the rebound action of the pressing spring 904, and the rotating motor 201 is controlled to continue to rotate forward, so that the moving block 4 drives the pushing block 401 to push the metal product through the bottom of the laser detector 7, so that the laser beam emitted by the laser detector 7 detects the flatness of the surface of the metal product. The metal product passes through one side of the laser detector 7 and rests on the bottom of another set of pressing rollers 906. The pressing rollers 906 on both sides of the laser detector 7 can press and fix the metal products to ensure that the metal products will not lift up when moving at the bottom of the laser detector 7, until the moving block 4 moves to the side away from the rotating motor 201 inside the rectangular groove 102, so that the pushing block 401 can push the metal products out of the top frame 1. After the metal products are pushed out of the top of the top frame 1, the rotating motor 201 is controlled to reverse, driving the moving screw 104 to reverse, so that the moving block 4 on the surface of the moving screw 104 moves in the opposite direction of the rotating motor 201 inside the rectangular groove 102, and repeat to place another group of metal products on the top of the top frame 1 for flatness detection.
