DETAILED DESCRIPTION

[0032] The application will be further described in detail below in combination with the drawings.

[0033] The embodiment of the application discloses a combined bolt automatic assembling and processing device.

[0034] Referring to Figure 1 , Figure 2 , the combined bolt automatic assembling and processing device comprises an assembling table 1, a material conveying turntable 10 controlled by a motor is rotationally arranged on the assembling table 1, a plurality of limiting grooves 11 for clamping the light pole are uniformly and circularly arranged on the outer circumferential surface of the material conveying turntable 10, and the maximum outer diameter of the head of the light pole is greater than the inner diameter of the limiting groove 11.

[0035] As Figure 1 , Figure 2 indicated, the device further comprises a light pole vibrating disc 2 and a gasket vibrating disc 3, the light pole vibrating disc 2 sequentially sends the light poles into the limiting grooves 11 in the light pole feeding stations through a material channel.

[0036] As Figure 3 , Figure 4 indicated, the device further comprises a first detection mechanism 4 opposite to the material channel of the light pole vibrating disc 2, the first detection mechanism 4 comprises a first detection table 40 fixedly arranged on the assembling table 1, the upper surface of the first detection table 40 is formed with a first detection groove 41 for inserting the bottom of the light pole from top to bottom on the first detection table 40, the length of the first detection groove 41 extends along the rotating path of the light pole, and the width of the first detection groove 41 is matched with the outer diameter of the light pole.

[0037] As Figure 3 , Figure 4 indicated, when the qualified light pole is sent into the limiting groove 11 from the discharging port of the material channel of the light pole vibrating disc 2, the light pole is inserted into the first detection groove 41 below under the action of gravity, and the head of the light pole is limited above the material conveying turntable 10 because the maximum outer diameter of the head of the light pole is greater than the inner diameter of the limiting groove 11, and the head of the light pole is in contact with the upper surface of the material conveying turntable 10.

[0038] As Figure 3 , Figure 4As shown, the first detection mechanism 4 further comprises two guide pieces 400 fixedly arranged on the assembling table 1, the guide pieces 400 are oppositely arranged, and a guide groove 401 with a width matching that of the light pole is formed between the guide pieces 400; the guide groove 401 is located directly below the discharge port of the light pole vibration disc 2 channel, and the qualified light pole can be sequentially and smoothly sent into the limiting groove 11 after passing through the guide groove 401, while the defective light pole that has been bent and deformed can be rotated and corrected to ensure that the direction of the bent side of the light pole is opposite to the first detection groove 41 before entering the guide groove 401. Therefore, when the defective light pole that has been bent and deformed is sent into the limiting groove 11, the bottom of the defective light pole cannot be smoothly inserted into the first detection groove 41 below, and finally the bottom of the defective light pole will fall on the upper surface of the first detection table 40, so that the head of the defective light pole is in a raised state.

[0039] As shown in Figure 3 , Figure 4 , the upper surface of the first detection table 40 is further integrally formed with a blocking bar 402 located on each side of the first detection groove 41, and the blocking bar 402 is used to limit the bottom of the defective light pole on the upper surface of the first detection table 40.

[0040] As shown in Figure 3 , Figure 4 , the first screening mechanism 5 is further arranged behind the first detection mechanism 4, and the first screening mechanism 5 comprises two groups of first support frames 52 fixedly installed on the assembling table 1, each group of first support frames 52 is slidably provided with a sliding block 53 along the radial direction of the material conveying turntable 10, and the first support frame 52 is further provided with a first spring 54 extending in the sliding direction of the sliding block 53. One end of the first spring 54 abuts against the inner side wall of the first support frame 52, and the other end of the first spring 54 abuts against the opposite sliding block 53. The first screening piece 50 is arranged above the limiting groove 11 between the two sliding blocks 53, and the first screening piece 50 is located below the two sliding blocks 53. The first spring 54 is used to push the first screening piece 50 to translate away from the rotating shaft of the material conveying turntable 10 until the first screening piece 50 is pushed to be directly above the limiting groove 11.

[0041] As shown in Figure 3 , Figure 4As shown, the first screening member 50 and the upper surface of the material conveying turntable 10 are spaced apart to allow the qualified light pole head to pass through. The material blocking frame 12 is provided with a first screening passage 51 corresponding to the first screening member 50, and the first detection table 40 extends below the first screening member 50. When the qualified light pole is driven by the material conveying turntable 10 to rotate to the first screening passage 51, the head of the qualified light pole can smoothly pass through the gap below the first screening member 50, and the bottom of the qualified light pole is limited in the limiting groove 11 under the limitation of the first detection groove 41, which can ensure that the qualified light pole is stably limited and finally smoothly rotates backward.

[0042] The head of the defective light pole in the elevated state will interfere with the first screening member 50. As the defective light pole gradually approaches the first screening passage 51, the defective light pole will continuously compress the first spring 54 by pushing the first screening member 50. Since the bottom of the defective light pole is not limited in the first detection groove 41, when the defective light pole moves to the first screening passage 51, the defective light pole will be pushed out of the limiting groove 11 to the first screening passage 51 by the first screening member 50 under the action of the elastic force of the first spring 54, and finally separated from the material conveying turntable 10, so as to realize automatic rejection of the defective light pole with bending deformation. By rejecting defective products in time, the yield of finished products can be improved, and the rate of defective products can be reduced.

[0043] As shown in Figure 2 , Figure 4 , the second detection mechanism 6 is located behind the first screening mechanism 5. The second detection mechanism 6 includes a second detection table 60 fixedly arranged on the assembly table 1, and the second detection table 60 is located on the rotating path of the light pole. The upper surface of the second detection table 60 is obliquely inclined upward away from the first screening mechanism 5 and provided with a detection inclined surface 61. The second detection table 60 is provided with two horizontal trigger plates 62 arranged above the detection inclined surface 61, and a gap slot 63 for the light pole to pass through is formed between the two horizontal trigger plates 62. The width of the gap slot 63 is matched with the outer diameter of the qualified light pole, and the gap slot 63 extends along the rotating direction of the material conveying turntable 10.

[0044] As shown in Figure 2 , Figure 4As shown, the second detection table 60 is provided with a plurality of guide rods arranged vertically, the trigger plate 62 is arranged vertically on the guide rods, the outer part of each guide rod is sleeved with a second spring 64, and the second spring 64 is telescopic along the lifting direction of the trigger plate 62. The upper end of the second spring 64 is in contact with the guide rod, and the lower end of the second spring 64 is in contact with the upper surface of the trigger plate 62. In the natural state, the second spring 64 is used to push the trigger plate 62 downward. The second detection mechanism 6 further comprises a photoelectric sensor 65 for sensing the displacement of the trigger plate 62. The photoelectric sensor 65 comprises a light emitter, a receiver and a detection circuit, and the light emitter and the receiver are arranged face to face on both sides of the trigger plate 62. The light emitter is used to emit infrared light or visible light, and the receiver can receive the light in the absence of obstacles. When the displacement of the trigger plate 62 is greater than a threshold value, the light will be blocked by the upwardly displaced trigger plate 62, and at this time the detection circuit will output a switch trigger signal with a delay to complete a control action.

[0045] As shown in Figure 4 , Figure 5 , the second screening mechanism 7 is further included. The second screening mechanism 7 comprises two groups of second support frames 70 fixedly installed on the assembly table 1, and a screening air cylinder 71 fixedly arranged between the two groups of second support frames 70 and arranged above the material conveying turntable 10. The piston rod of the screening air cylinder 71 is telescopic along the radial direction of the assembly table 1. A push plate 72 is fixedly arranged on the piston rod of the screening air cylinder 71 and arranged above the material conveying turntable 10. The push plate 72 is used to push the light rod out of the limiting groove 11. The material blocking frame 12 is provided with a second screening passage 13 corresponding to the push plate 72. A blocking block 73 is further fixedly arranged on the piston rod of the screening air cylinder 71 and used to block the opening of the second screening passage 13. The shape of the blocking block 73 is matched with the shape of the second screening passage 13. The screening air cylinder 71 is controlled by the trigger signal output by the photoelectric sensor 65,

[0046] As shown in Figure 2 , Figure 3 , the first support frame 52 and the second support frame 70 are provided with a cross frame 14 arranged above the limiting groove 11 and vertically lifted. A third spring 15 is sleeved above the cross frame 14 and is telescopic along the lifting direction of the cross frame 14. The upper end of the third spring 15 is in contact with the opposite first support frame 52 or second support frame 70, and the lower end of the third spring 15 is in contact with the upper surface of the cross frame 14. In the natural state, the third spring 15 is used to push the cross frame 14 downward until the head of the light rod below is in contact with the cross frame 14. The cross frame 14 is located directly above the second detection table 60, and the material blocking frame 12 above the second detection table 60 is in contact with the outer side wall of the light rod in the limiting groove 11.

[0047] When the surface of the polished rod has protruding defects, it will also cause the subsequent gasket to be unable to be smoothly arranged outside the polished rod, and therefore the above-mentioned defective polished rod needs to be removed. When the polished rod falls on the detection slope 61, as the transmission carousel 10 rotates, the height of the polished rod will gradually rise along the detection slope 61, and at the same time, since the material blocking frame 12 above the second detection table 60 interferes with the outer side wall of the polished rod in the limiting groove 11, the polished rod will also rotate while its height is constantly rising.

[0048] The qualified polished rod can stably rise along the detection slope 61 under the depression of the cross frame 14 and can smoothly pass through the accommodation groove 63, and when the defective polished rod with protrusions on the surface enters the accommodation groove 63, as the polished rod rotates and rises, once the protrusions on the surface of the polished rod contact the trigger plate 62, the polished rod will lift the trigger plate 62 by a distance as the polished rod is further lifted, and at this time, the photoelectric sensor 65 can judge whether the current polished rod is defective according to the rising displacement of the detected trigger plate 62. When the defective polished rod moves to one side of the push plate 72, the piston rod of the screening cylinder 71 will retract and push the defective polished rod out of the limiting groove 11 through the push plate 72, and during this period, the blocking block 73 synchronously opens the opening of the second screening channel 13 to ensure that the defective polished rod is separated from the transmission carousel 10.

[0049] As shown in Figure 2 , Figure 5 , the third screening mechanism 8 further includes a linkage assembly 82, and the linkage assembly 82 includes a mounting seat 85 fixedly installed on the assembly table 1, a sliding frame 86 slidingly arranged on the mounting seat 85 along the radial direction of the transmission carousel 10, and a gear rack 87 arranged on the opposite inner side walls of the sliding frame 86. The mounting seat 85 is rotationally arranged with a driven gear 88 between the two gear racks 87, and the outer circumferential surface of the driven gear 88 is provided with a tooth surface 880 and a light surface 881.

[0050] As shown in Figure 2 , Figure 5 , the tooth surface 880 of the driven gear 88 is used for periodic engagement with the two gear racks 87, and when the tooth surface 880 is engaged with one side of the gear rack 87, the driven gear 88 will push the sliding frame 86 to move towards the third detection table 80 as the driven gear 88 rotates. As the driven gear 88 further rotates, when the driven gear 88 rotates to engage with the other gear rack 87, the driven gear 88 will push the sliding frame 86 to move away from the third detection table 80, and this cycle is repeated.

[0051] As shown in Figure 2 , Figure 5 , the rotation shaft of the driven gear 88 is coaxially fixed with the driving gear 89, and the driving gear 89 is located directly above the driven gear 88. The bottom surface of the material conveying turntable 10 is coaxially fixed with the gear ring 17, and the gear ring 17 rotates synchronously with the material conveying turntable 10. The gear ring 17 and the driving gear 89 are in meshing relationship, and when the material conveying turntable 10 rotates, the gear ring 17 will drive the driving gear 89 to rotate synchronously, and the driven gear 88 will rotate synchronously with the driving gear 89.

[0052] As shown in Figure 2 , Figure 5 , the sliding frame 86 is slidingly provided with a sliding rod 860 on the side wall of the third detection station 80, and the sliding rod 860 slides along the radial direction of the material conveying turntable 10. The sliding rod 860 is fixedly installed with a pressing plate 83 on the side wall of the third detection station 80. The sliding rod 860 is externally sleeved with a fourth spring 861, and the fourth spring 861 is telescopic along the sliding direction of the sliding rod 860. One end of the fourth spring 861 is in abutment with the sliding frame 86, and the other end of the fourth spring 861 is in abutment with the outer side wall of the sliding rod 860, and the fourth spring 861 is used to drive the pressing plate 83 to move away from the sliding frame 86. The sliding frame 86 is used to drive the pressing plate 83 to periodically reciprocate along the radial direction of the material conveying turntable 10, and the material blocking frame 12 is provided with a third screening channel 84 corresponding to the pressing plate 83.

[0053] If the length of the optical rod is less than the standard value, the optical rod is also a defective product. Therefore, the bottom of the qualified optical rod can be smoothly moved into the third detection groove 81, and when the qualified optical rod moves to be opposite to the pressing plate 83, the pressing plate 83 will apply a pushing force to the optical rod under the driving of the sliding frame 86. Since the bottom of the qualified optical rod is limited in the third detection groove 81 at this time, the qualified optical rod will not be separated from the third screening channel 84. The defective optical rod with a length less than the standard value will be pushed out of the third screening channel 84 under the pushing force of the pressing plate 83 since the bottom cannot be inserted into the third detection groove 81. Then the pressing plate 83 will be automatically reset under the driving of the sliding frame 86 to prepare for the next round of screening work.

[0054] As shown in Figure 6 , the discharge port of the gasket vibration disc 3 material channel extends below the material conveying turntable 10, and the gasket sent out from the gasket vibration disc 3 material channel is vertically arranged and located on the rotation path of the optical rod. The assembly station 1 is provided with a discharge channel 16 located behind the discharge port of the gasket vibration disc 3 material channel. The gasket is pushed out of the discharge port of the gasket vibration disc 3 material channel by the optical rod, and there is no need to supplement the optical rod in the empty position limiting groove 11.

[0055] The implementation principle is that the bad light pole that has a bending deformation will be pushed out of the limiting groove 11 by the first screening member 50 under the elastic force of the first spring 54 to the first screening channel 51, and finally separated from the material conveying turntable 10, so as to realize automatic rejection of the bad light pole that has a bending deformation, and improve the yield of finished products and reduce the rate of defective products by timely rejecting defective products. When the bad light pole with a protrusion on the surface moves to one side of the push plate 72, the piston rod of the screening air cylinder 71 will be retracted and push the bad light pole out of the limiting groove 11 through the push plate 72, and during this period, the blocking block 73 synchronously opens the opening of the second screening channel 13 to ensure that the bad light pole is separated from the material conveying turntable 10. The bad light pole with a length less than the standard value cannot be inserted into the third detection groove 81 at the bottom, so under the pushing force of the pressing plate 83, it will be pushed out of the third screening channel 84. Then the pressing plate 83 will be automatically returned and reset under the driving of the sliding frame 86 to prepare for the next round of screening work.

[0056] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
