DETAILED DESCRIPTION

[0029] The present invention is further described below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 15 As shown, the bucket tooth seat 11 includes a bucket tooth plate 11-1 and bucket teeth 11-2, and a plurality of bucket teeth 11-2 are welded on the bucket tooth plate 11-1. A bucket tooth seat automatic assembly workstation is used to weld and fix the bucket tooth plate 11-1 and bucket teeth 11-2 to form a bucket tooth seat 11. The bucket tooth seat automatic assembly workstation includes a bucket tooth loading rack 1, a bucket tooth plate loading rack 2, a robot automatic grabbing mechanism 3, a turning positioner 4, a bucket tooth plate automatic positioning and clamping mechanism 5, a robot automatic spot welding mechanism 6, a bucket tooth seat automatic unloading and transplanting mechanism 7, a conveyor chain preheating furnace 8, a bucket tooth seat automatic material receiving and transplanting mechanism 9 and a bucket tooth seat automatic turning mechanism 10. The bucket tooth loading rack 1 is used to store the bucket teeth 11 - 2 , the bucket tooth plate loading rack 2 is used to store the bucket tooth plate 11 - 1 , and the robot automatic grasping mechanism 3 is used to grasp the bucket tooth plate 11 - 1 and the bucket teeth 11 - 2 and send them to the next station.

[0031] like Figures 2 to 4 As shown, the robot automatic grasping mechanism 3 includes a robot 3-1 fixed on a robot base 3-4, and the robot 3-1 is connected with an electromagnet 3-2 for grasping a bucket tooth plate 11-1 and a bucket tooth automatic grasping mechanism 3-3 for grasping bucket teeth 11-2. The bucket tooth automatic grasping mechanism 3-3 includes a connecting frame 3-31, and the connecting frame 3-31 provides fixed support for various components of the bucket tooth automatic grasping mechanism. A linear moving device and a bracket 3-39 are provided on the connecting frame 3-31. Preferably, the linear moving device includes a linear guide rail 3-33, and a slider 3-34 is slidably provided on the linear guide rail 3-33. The slider 3-34 is provided with two pieces. Preferably, two linear guide rails 3-33 are provided in parallel at the bottom of the connecting frame 3-31, and two sliders 3-34 are slidably provided between the two linear guide rails 3-33. The provision of two linear guide rails 3-33 can increase the stability of the slider 3-34 when sliding. Two groups of clamps are symmetrically arranged on the linear moving device, one group of clamps is arranged on each slider 3-34, and the two groups of clamps cooperate to clamp the bucket teeth 11-2. The clamps include a slide plate 3-35 arranged on the slider 3-34, and the slide plate 3-35 is movably connected to the slider 3-34 by bolts. The slide plates 3-35 of the two groups of clamps are connected to the pneumatic clamps 3-322, and the opening and closing of the pneumatic clamps 3-322 will drive the two slide plates 3-35 to move closer and farther synchronously along the linear guide 3-33, so that the two groups of clamps complete the clamping and loosening actions. The slide plate 3-35 is movably connected with an adapter block 3-36, and a clamping block 3-37 and a positioning pin 3-38 are provided on the side of the adapter block 3-36 facing the other clamping jaw. In the process of clamping the bucket tooth 11-2, the pneumatic clamping jaw 3-322 closes and drives the two slide plates 3-35 to move closer synchronously, so that the positioning pins 3-38 of the two sets of clamping jaws are respectively inserted into the holes on both sides of the bucket tooth 11-2, and the clamping blocks 3-37 of the two sets of clamping jaws are clamped on both sides of the bucket tooth 11-2.

[0032] The bracket 3-39 is arranged on the rear side of the connecting frame 3-31 by bolts, and the bracket 3-39 extends vertically toward the bottom of the connecting frame 3-31. The side of the bracket 3-39 away from the connecting frame 3-31 is provided with a second electromagnet mounting block 3-312 through a rotating shaft 3-311. Specifically, the side of the bracket 3-39 away from the connecting frame 3-31 is a U-shaped opening structure, and the second electromagnet mounting block 3-312 extends into the U-shaped opening of the bracket 3-39, and the second electromagnet mounting block 3-312 is rotated and fixed by the rotating shaft 3-311 fixed on the bracket 3-39. A spring 3-310 for limiting the rotation range of the second electromagnet mounting block 3-312 is arranged between the second electromagnet mounting block 3-312 and the bracket 3-39, and a second electromagnet 3-313 is arranged on the side of the second electromagnet mounting block 3-312 facing the clamping jaw. After the two sets of jaws clamp the bucket tooth 11-2, the second electromagnet 3-313 is energized. At this time, the second electromagnet 3-313 has magnetic force, which attracts the side of the bucket tooth 11-2, so that the bucket tooth 11-2 will not shake.

[0033] As a preferred embodiment of this embodiment, the clamping block 3-37 is a cylinder with a threaded hole provided on the cylinder, and the clamping block 3-37 is movably connected to the adapter block 3-36 by bolts.

[0034] The working process of the automatic grabbing mechanism of bucket teeth is as follows: before grabbing, the pneumatic clamp 3-322 is in an open state, and the second electromagnet 3-313 is in a non-magnetic state. At this time, the positioning pins 3-38 located on the bucket teeth 11-2 on both sides are aligned with the holes on the side of the bucket teeth 11-2. When grabbing, the pneumatic clamp 3-322 is closed, driving the slide plate 3-35 to approach along the linear guide 3-33 through the slider 3-34, driving the positioning pin 3-38 to insert into the holes on both sides of the bucket teeth 11-2, and driving the clamp block 3-37 to clamp the bucket teeth 11-2. Subsequently, the second electromagnet 3-313 is energized, and at this time the second electromagnet 3-313 has magnetic force, sucking the side of the bucket teeth 11-2, so that the bucket teeth 11-2 will not shake. The automatic grabbing mechanism of bucket teeth completes grabbing the bucket teeth 11-2, and then the robot moves the bucket teeth 11-2 to the next station.

[0035] like Figure 1 As shown, the bucket tooth plate automatic positioning clamping mechanism 5 is installed on the turning positioner 4. Figures 5 to 7As shown, the automatic positioning and clamping mechanism 5 for bucket tooth plates includes a frame 5-1, on which a left slide plate 5-5 and a right slide plate 5-2 are slidably connected, and the left slide plate 5-5 and the right slide plate 5-2 are both provided with a positioning block 5-7 and a top block 5-4 for longitudinally clamping the bucket tooth plate 11-1, and the top block 5-4 is connected to the telescopic rod of the oil cylinder 5-3; the left slide plate 5-5 and the right slide plate 5-2 are both provided with a clamping block 5-6 that cooperates with each other for transversely clamping the bucket tooth plate 11-1; the left slide plate 5-5 is transmission-connected to the left-hand screw 5-9 through a left nut seat, and the right slide plate 5-2 is transmission-connected to the right-hand screw 5-10 through a right nut seat, and the left-hand screw 5-9 and the right-hand screw 5-10 are transmission-connected through a transmission connecting piece. The transmission connection includes a rotating shaft and two couplings. One end of the rotating shaft is connected to the left-hand screw 5-9 through a coupling, and the other end of the rotating shaft is connected to the right-hand screw 5-10 through another coupling. The left-hand screw 5-9 is connected to the hydraulic motor 5-8, and the hydraulic motor 5-8 drives the left-hand screw 5-9 to rotate, and the left-hand screw 5-9 drives the right-hand screw 5-10 to rotate through the rotating shaft. The left slide 5-5 and the right slide 5-2 are both provided with linear motion guide limiters between the frame 5-1, such as the slider on the slide and the guide rail on the frame 5-1. The rotation of the left-hand screw 5-9 will drive the left slide 5-5 to do linear motion through the left nut seat, and the rotation of the right-hand screw 5-10 will drive the right slide 5-2 to do linear motion through the right nut seat. The left slide 5-5 and the right slide 5-2 move closer or farther at the same time. When the left slide 5-5 and the right slide 5-2 move toward each other, the bucket tooth plate 11-1 sent from the previous station is clamped, and the bucket tooth plate 11-1 is clamped horizontally by the clamping block 5-6 on the left slide 5-5 and the clamping block 5-6 on the right slide 5-2. The positioning block 5-7 and the top block 5-4 on the left slide 5-5 and the right slide 5-2 are used to clamp the bucket tooth plate 11-1 longitudinally, and the top block 5-4 cooperates with the positioning block 5-7 to clamp the bucket tooth plate 11-1 longitudinally under the telescopic action of the oil cylinder 5-3.

[0036] like Figure 1 As shown, a robot automatic spot welding mechanism 6 for welding and fixing the bucket tooth plate 11 - 1 and the bucket tooth 11 - 2 is arranged next to the bucket tooth plate automatic positioning and clamping mechanism 5 .

[0037] The bucket tooth seat automatic unloading and transplanting mechanism 7 is used to transport the bucket tooth seat 11 that has been welded on the bucket tooth plate automatic positioning clamping mechanism 5 to the next station. Figures 8 to 10As shown, the bucket tooth seat automatic unloading and transplanting mechanism 7 includes a slide plate Ⅰ7-3 connected to the ground rail Ⅰ7-1, a travel drive Ⅰ7-4 is fixed on the slide plate Ⅰ7-3, the slide plate Ⅰ7-3 is connected to the bracket Ⅰ7-2 through the lifting bracket 7-5, and a cylinder Ⅰ7-6 is connected between the bracket Ⅰ7-2 and the slide plate Ⅰ7-3. The slide plate Ⅰ7-3 can move relative to the ground rail Ⅰ7-1 in the following way: a rack is provided on the ground rail Ⅰ7-1, the travel drive Ⅰ7-4 on the slide plate Ⅰ7-3 is connected to the gear transmission, and the gear connected to the travel drive Ⅰ7-4 is meshed with the rack on the ground rail Ⅰ7-1, and the travel drive Ⅰ7-4 is driven in the positive and negative directions to drive the slide plate Ⅰ7-3 to move forward or backward relative to the ground rail Ⅰ7-1. The bracket Ⅰ7-2 is driven to rise and fall by the cylinder Ⅰ7-6, and then controlled to receive the bucket tooth seat 11 at the previous station and to transport the bucket tooth seat 11 to the next station. The lifting bracket 7-5 is used to assist the bracket I 7-2 in lifting.

[0038] The bucket tooth seat automatic material receiving and transferring mechanism 9 is used to transport the bucket tooth seat 11 heated out of the conveyor chain preheating furnace 8 to the bucket tooth seat automatic turning mechanism 10.

The movement mode of the slide II 9-2 of the bucket tooth seat automatic material receiving and transferring mechanism 9 relative to the ground rail II 9-1 is the same as the movement mode of the slide I 7-3 of the bucket tooth seat automatic material unloading and transferring mechanism 7 relative to the ground rail I 7-1. The cylinder II 9-5 controls the lifting slide 9-6 to lift and lower along the side of the column 9-4, thereby realizing the lifting and lowering of the bracket II 9-7. The bracket II 9-7 is used to receive the bucket tooth seat 11 at the previous station and transport the bucket tooth seat 11 to the next station.

[0039] The bucket tooth seat automatic turning mechanism 10 is used to adjust the position of the bucket tooth seat 11, so that the truss manipulator can automatically move the bucket tooth seat 11 to the next station.

Preferably, the pressing block 10-8 is provided with a rolling pressing wheel 10-9. During the clamping process, the rolling pressing wheel 10-9 rolls with the bucket tooth seat 11, which is conducive to clamping. After completing the clamping of the bucket tooth seat 11, the cylinder III 10-2 extends out to drive the cross beam 10-3 to perform a flipping motion through the connecting rod mechanism to adjust the position of the bucket tooth seat 11.

[0040] The specific operation steps of the bucket tooth seat automatic assembly workstation are as follows:

[0041] 1. The robot automatic grabbing mechanism 3 grabs the bucket tooth plate 11 - 1 from the bucket tooth plate material rack 2 and places it on the bucket tooth plate automatic positioning and clamping mechanism 5 , and the bucket tooth plate automatic positioning and clamping mechanism 5 positions and clamps the bucket tooth plate 11 - 1 .

[0042] 2. The turning positioner 4 rotates 90 degrees, driving the bucket tooth plate 11-1 to a vertical state.

[0043] 3. The robot automatic grabbing mechanism 3 grabs the bucket tooth 11-2 from the bucket tooth loading rack 1 and assembles it with the bucket tooth plate 11-1 placed on the bucket tooth plate automatic positioning clamping mechanism 5. At the same time, the robot automatic spot welding mechanism 6 spot welds the bucket tooth 11-2 and the bucket tooth plate 11-1 into one. Only one bucket tooth 11-2 is grabbed, assembled and spot welded each time.

[0044] 4. Repeat step 3 until a complete set of bucket tooth seat 11 is spot welded.

[0045] 5. After spot welding of a set of bucket tooth seat 11 is completed, the turning positioner 4 is rotated 90 degrees in the same direction again to drive the bucket tooth seat 11 to a horizontal state, and the bucket tooth seat automatic unloading and transfer mechanism 7 takes the bucket tooth seat 11 away and transfers it to the conveyor chain preheating furnace 8.

[0046] 6. After the bucket tooth seat 11 is heated by the conveyor chain preheating furnace 8, the bucket tooth seat automatic material receiving and transferring mechanism 9 transfers the bucket tooth seat 11 to the bucket tooth seat automatic turning mechanism 10. The bucket tooth seat automatic turning mechanism 10 automatically clamps the bucket tooth seat 11, and then rotates it 90 degrees to face the bucket tooth 11-2 in the bucket tooth seat 11 upward.

[0047] 7. Finally, the truss manipulator automatically moves the bucket tooth seat 11 to the next station.
