[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] The utility model proposes an integrated automated drilling and tapping device, comprising: a conveyor chain 1, a middle positioning frame 2 and a multi-axis drilling and tapping module 3. The two ends of the conveyor chain 1 are connected to a main support frame 101 through a chain shaft. The spaced array of the conveyor chain 1 is provided with a middle support roller 102. The conveyor chain 1 and the middle support roller 102 move in a circular manner to realize the conveyance of the differential case between the two multi-axis drilling and tapping modules 3, and the differential case drilled under the multi-axis drilling and tapping module 3 is conveyed to the other multi-axis drilling and tapping module 3 for tapping operation. Compared with the disc-type circumferential automatic conveying mode, the linear conveyor chain 1 takes up less space and is more convenient to connect to conveying equipment such as conveyor belts.

[0031] A middle positioning frame 2 is symmetrically provided in the middle of the conveying chain 1, a middle bracket 201 is fixedly provided at the head end of the middle positioning frame 2, a first hydraulic cylinder 202 is fixed on the side of the middle positioning frame 2, an upper horizontal slide 203 is provided on the upper part of the middle positioning frame 2 for horizontal sliding, a second hydraulic cylinder 204 is fixedly provided on the top of the upper horizontal slide 203, a guide slide 205 is fixedly provided on the head end of the telescopic rod of the second hydraulic cylinder 204, side fixing clamps 206 are provided on both sides of the top of the upper horizontal slide 203 for horizontal sliding, the telescopic rod of the first hydraulic cylinder 202 is fixedly connected to the upper horizontal slide 203, an oblique groove 207 is provided at the rear part of the side fixing clamp 206, and the guide slide 205 is respectively slidably connected to the oblique groove 207 of the side fixing clamps 206 on both sides, a third hydraulic cylinder 208 is fixedly provided on the top of the front side of the side fixing clamp 206, an upper fixed block 209 is fixed on the top of the telescopic rod of the third hydraulic cylinder 208, and a The pressure cylinder 208 is shortened and drives the upper fixed block 209 to move downward. The upper fixed block 209 presses the top of the differential case. The bottom of the middle positioning frame 2 is fixed to the telescopic rod of the fourth hydraulic cylinder 210. The side fixing clamp 206 is above the conveying chain 1. The middle bracket 201 is vertically below the multi-axis drilling and tapping module 3. When the guide slide 205 moves horizontally, the side fixing clamp 206 moves oppositely. The side fixing clamp 206 clamps the middle differential case. A multi-axis drilling and tapping module 3 is provided above the conveying chain 1. The multi-axis drilling and tapping module 3 is fixedly connected to the lifting rod of the lifting base 301. The lifting base 301 is fixed to the outside of the main support frame 101. The hydraulic rod of the lifting base 301 is lowered to lower the multi-axis drilling and tapping module 3. The hydraulic rod of the lifting base 301 is lowered to lower the multi-axis drilling and tapping module 3. The multi-axis drilling and tapping module 3 contacts the lower differential case for drilling or tapping.

[0032] In the disclosed embodiment, the fourth hydraulic cylinder 210 is fixed on the outside of the main support frame 101, the middle support frame 201 is located in the gap between the middle support rollers 102, and the middle positioning frame 2 is located below the conveyor chain 1. The middle support frame 201 moves upward to push the differential case and the middle support roller 102 to separate, thereby reducing the pressure on the middle support roller 102 and the conveyor chain 1 during the processing and fixing of the differential case, reducing the situation where the conveyor chain 1 is stretched and deformed due to pressure, and extending the service life of the conveyor chain 1.

[0033] Embodiment 2, based on embodiment 1, the top of the middle support roller 102 is connected and fixed to a cylinder, the cylinder of the middle support roller 102 and the center of the differential case are fitted and slid, and the differential case is slid into the cylinder of the middle support roller 102 to realize the positioning operation of the differential case, and realize the allocation operation of multiple differential case interval positions, ensuring that the two multi-axis drilling and tapping modules 3 move down at the same time to process the lower differential case, eliminating the manual allocation and measurement operation of the differential case interval by personnel.

[0034] The working principle of this embodiment: the multi-axis drilling and tapping modules 3 are two for drilling and tapping respectively, and a plurality of drilling bits and tapping bits are arranged below the multi-axis drilling and tapping modules 3 to perform drilling and tapping at multiple positions at the same time. The hydraulic rod of the lifting base 301 is lowered to realize the lowering of the multi-axis drilling and tapping module 3, and the multi-axis drilling and tapping module 3 contacts the differential case below to perform the processing flow of drilling and tapping. The differential case is placed on the middle support roller 102, and the conveying chain 1 is driven to rotate by the motor. The middle support roller 102 moves in a circular motion with the conveying chain 1 to realize automatic conveying of the differential case. The conveying chain 1 and the middle support roller 102 move in a circular motion to realize the differential case between two multi-axis drilling and tapping modules. The conveying between the axis drilling and tapping modules 3 is to convey the differential case drilled below the multi-axis drilling and tapping module 3 to another multi-axis drilling and tapping module 3 for tapping. The two multi-axis drilling and tapping modules 3 realize the drilling and tapping process. Compared with the disc-type circumferential automatic conveying mode, the linear conveying chain 1 saves more space, reduces space occupancy, and is more convenient for other automated equipment such as a robotic arm to place the differential case on the middle support roller 102. The conveying chain 1 and the middle support roller 102 dock the tapped differential case and convey it to the next conveyor belt, realizing the automation of loading and unloading, eliminating the need for manual transfer of the differential case after drilling and tapping;

[0035] After the differential moves to the bottom of the multi-axis drilling and tapping module 3, the fourth hydraulic cylinder 210 extends and supports the middle positioning frame 2 and the middle bracket 201 to rise. The middle bracket 201 rises and contacts the bottom of the differential case and pushes the differential case and the middle support roller 102 to separate. The first hydraulic cylinder 202 shortens, and the first hydraulic cylinder 202 pulls the upper horizontal slide 203 to move toward one side of the differential. The upper horizontal slide 203 and the side fixing clamp 206 move synchronously, and the side fixing clamp 206 moves to both sides of the differential. The second hydraulic cylinder 204 shortens, and the second hydraulic cylinder 204 pulls the guide slide 205 away from the side fixing clamp 206. The guide slide 205 guides the two side fixing clamps 206 to move closer through the inclined slot 207. The side fixing clamp 206 moves close to the differential case that clamps the middle. The third hydraulic cylinder 208 shortens and drives the upper fixing clamp 206 to move closer. The fixed block 209 moves downward, and the upper fixed block 209 presses down on the top of the differential case to fix the differential case. The differential case undergoes drilling and tapping processes. The middle bracket 201 moves upward to push the differential case and the middle support roller 102 to separate, reducing the pressure on the middle support roller 102 and the conveyor chain 1 during differential case processing, reducing the tensile deformation of the conveyor chain 1 due to pressure, and extending the maintenance interval and service life of the conveyor chain 1. When the differential needs to move, the side fixing clamp 206 moves to the outside of the conveyor chain 1 with the upper horizontal slide 203 to prevent the side fixing clamp 206 from blocking the movement of the differential case. The middle positioning frame 2 and the middle bracket 201 descend at the same time, and the middle bracket 201 descends below the middle support roller 102. The differential case moves downward to the middle support roller 102, and the differential case moves along with the middle support roller 102.
