DETAILED DESCRIPTION

[0023] The technical solution protected by the present invention is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, an automatic punching detection device for shaft tube products includes: a dividing plate 8, on which a feeding mechanism 1, a positive and negative detection mechanism 2, a punching mechanism 3, a blowing mechanism 4, a detection mechanism 5, a first unloading mechanism 6, and a second unloading mechanism 7 are sequentially arranged, and a circle of baffles 10 are arranged on the periphery of the dividing plate 8, and the baffles 10 are respectively provided with a through hole at the punching mechanism 3, the first unloading mechanism 6, and the second unloading mechanism 7. The dividing plate 8 rotates, while the baffle 10 does not rotate. When the product arrives at the several mechanisms along with the fixture, the product falls into the corresponding station;

[0025] Among them, the feeding mechanism 1 is a jig feeding at the dividing plate 8, the front and back detection mechanism 2 is used to detect the front and back of the product, the punching mechanism 3 is used to punch the product, the blowing mechanism 4 is used to blow away the iron filings at the product, the detection mechanism 5 is used to detect whether the product is punched in place, the first unloading mechanism 6 is used for unloading good products, and the second unloading mechanism 7 is used for unloading defective products.

[0026] like Figure 2As shown, the feeding mechanism 1 includes: a vibration plate 11, a straight material channel 12 connected to the vibration plate 11, and a clamping mechanism is arranged at the end of the straight material channel 12, and the clamping mechanism includes: a lateral moving mechanism 13, a longitudinal moving mechanism 14 and a clamping claw cylinder 15, and the clamping claw cylinder 15 is arranged at the lateral moving mechanism 13, and the lateral moving mechanism 13 is arranged at the longitudinal moving mechanism 14, and a sensor A16 is arranged at the corresponding straight material channel below the lateral moving mechanism 13. A vibration motor is also arranged at the straight material channel 12, and the products fed by the vibration plate 11 are fed from the straight material channel 12 in sequence. When the products are close to the clamping claw cylinder 15, the sensor A16 senses the products and transmits the information to the control system, and the control system controls the clamping claw cylinder 15 to clamp the products and put them into the fixture of the indexing plate 8.

[0027] like Figure 3 As shown, the front and back detection mechanism 2 includes: a lifting cylinder A21, a slider A23 arranged at the end of the piston rod of the lifting cylinder A21, and a guide rail A22 matched with the slider A23. A probe A24 is arranged at the lower end of the slider A23, and a corresponding position of the fixture of the indexing plate 8 is also provided with a through-shooting sensor. When the product reaches this mechanism, the lifting cylinder A21 is pressed down, driving the probe A24 to contact the product, and the through-shooting sensor senses the designated hole position on the product to determine whether the product is processed or front and back. If the product enters the next station for stamping normally, it will not be punched if it is unqualified.

[0028] like Figure 4 As shown, the punching mechanism 3 includes: a hydraulic cylinder 31, a punch 32 arranged at the end of the piston rod of the hydraulic cylinder 31, an upper template 33, a lower template 34, and a lifting cylinder 35. The lifting cylinder 35 is arranged below the lower template 34. When the product is in place, the piston rod of the lifting cylinder 35 retracts and the product falls into the hole of the lower template 34. The hydraulic cylinder 31 drives the punch 32 to punch a hole to perform the punching process.

[0029] Furthermore, in order to prevent the punch 32 from bringing out the product when it rises, a limit plate 38 is further provided below the upper template 33, and a limit spring 37 is provided between the limit plate 38 and the upper template 33. When the upper template 33 drives the punch 32 to rise, the limit plate 38 is still in contact with the product due to the spring force. After the punch 32 leaves the product, as the upper template 33 rises, the limit plate 38 finally separates from the product to prevent the product from being brought out by the punch 32.

[0030] Furthermore, a plurality of limit rods 36 are evenly arranged between the upper mold plate 33 and the lower mold plate 34 to prevent the punch 32 from over-punching.

[0031] In addition, a light sensor is also provided at the punching mechanism 3, and the optical fiber sensor detects whether the position is in place and whether the punch is damaged.

[0032] In the utility model, a blowing mechanism 4 is further arranged downstream of the punching mechanism 3, and the blowing mechanism 4 includes a blowing head. When the product is punched and reaches this station, the blowing head blows air to blow away the iron filings on the product.

[0033] like Figure 5 As shown, the detection mechanism 5 includes: a lifting cylinder B55, a slider B54 arranged at the piston rod of the lifting cylinder B55, and a guide rail B53 matched with the slider B54. A detection head 52 is arranged at the lower end of the slider B54, and the detection head 52 is electrically connected to the sensor B51. When the product reaches the detection mechanism 5, the lifting cylinder B55 drives the detection head 52 to descend, measures the hole height, and feeds back the information to the sensor B51. The sensor B51 feeds back the information to the control system. If the height is qualified, it is a good product, and if the height is unqualified, it is a defective product.

[0034] like Figure 6 As shown, the first unloading mechanism 6 includes: a transverse cylinder 61 and a stopper 62 fixed to the piston rod of the transverse cylinder. When the product reaches this station, due to the through hole at the baffle 10, the transverse cylinder 61 drives the stopper 62 to retract, and the product falls from the through hole at the baffle 10 into the lower slideway and finally enters the material box.

[0035] The first unloading mechanism 6 and the second unloading mechanism 7 are used to place good products and bad products respectively, and are respectively equipped with counters. When the count reaches a set value, the material box is full, and a prompt is given to replace the material box.

[0036] Among them, the slide is set to be S-shaped, and the placed product falls directly into the material box and damages the product. The S-shaped slide can play a buffering role.

[0037] The working principle of the present invention is:

[0038] The product is loaded from the vibration plate 11, and after passing through the straight material channel 12, the sensor A16 at the gripper cylinder 15 senses that the product is in place, and the gripper cylinder 15 grabs the product and puts it into the fixture on the indexing plate 8;

[0039] The indexing plate 8 rotates to bring the product to the front and back detection mechanism 2. When the product reaches this mechanism, the lifting cylinder A21 presses down, driving the probe A24 to contact the product. The corresponding sensor senses the designated hole position on the product to determine whether the product is processed or front and back. If the product is normal, it will enter the next station for stamping. If it is unqualified, it will not be punched;

[0040] When the product is not loaded upside down and enters the punching mechanism 3, the rod of the lifting cylinder 35 is retracted, and the product falls into the hole of the lower template 34. The hydraulic cylinder 31 descends to drive the upper template 33 to be fixed, and then the punch 32 punches. After the punching is completed, the punch 32 withdraws first, and the upper template 33 supports the limit plate 38 through the limit spring 37. After the punch withdraws, the upper template 33 drives the limit plate 38 to withdraw to prevent the product from being brought out from the lower template 34;

[0041] After punching is completed, the indexing plate 8 drives the product to the blowing mechanism 4, and the blowing head blows air to blow away the iron filings on the product;

[0042] After the air blowing is completed, the product reaches the detection mechanism 5, and the lifting cylinder B55 drives the detection head 52 to descend, measures the hole height, and feeds back the information to the sensor B51. The sensor B51 feeds back the information to the control system. If the height is qualified, it is a good product, and if the height is unqualified, it is a defective product;

[0043] Good products and defective products are unloaded through the good product unloading mechanism and the defective product unloading mechanism respectively to complete the punching process.

[0044] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
