Description

Technical Field

[0001] The invention relates to the technical field of automatic tube feeding, and in particular to an automatic feeding device for aviation precision seamless tubes and a use method thereof. Background Art

[0002] At present, the manufacturing of aviation ducts in my country is developing towards automation and unmanned operation, achieving the ability to quickly manufacture aviation ducts. However, due to the following two characteristics of aviation ducts, traditional automatic pipe feeding mechanisms are not applicable.

[0003] 1) There are many types of cutting lengths but few quantities: Aviation precision seamless steel pipes are processed in small batches and with many varieties, that is, a single outer diameter pipe is processed in hundreds of lengths at a time, and the number of pipes of one length is very small. 2) The original pipe lengths are varied: Since the aviation system has high requirements for the surface quality of pipes, the original pipes need to be ultrasonically inspected before use, and the pipes that do not meet the requirements must be cut off before selection and use, resulting in uneven lengths of the original pipes.

[0004] The traditional pipe feeding mechanism is less integrated and belongs to a separate feeding mechanism, which is separated from the feeding and cutting ends. In addition, the pipes need to be laid out and tilted for unloading. The feeding mechanism of a single outer diameter pipe occupies 6m 2 (Take the longest original pipe as an example, 3m, the conventional one is 2m*3m), the floor space occupied by pipes with various outer diameters is huge. At the same time, it is not suitable for the problem that the original pipes have different lengths. In order to solve the above problems, an automatic unloading and loading device for aviation precision seamless pipes is proposed. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes an automatic unloading and loading device for aviation precision seamless pipes and a method for using the same.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0007] An automatic unloading and loading device for aviation precision seamless pipes, comprising:

[0008] Pipe storage area, used to store pipes;

[0009] The pipe unloading area is connected to the pipe storage area and is used to carry a maximum of thirty pipes of irregular length at a time;

[0010] The material unloading and pushing mechanism is located at the lower end of the pipe unloading area and is used to support the pipe and push the pipe horizontally out from below the pipe unloading area;

[0011] The turning mechanism is used to move the pipe on the material unloading pushing mechanism to the material unloading positioning mechanism;

[0012] The pipe pushing mechanism is used to push the pipe on the unloading positioning mechanism to the feeding origin position;

[0013] The blanking positioning mechanism is used to measure the original length of the pipe.

[0014] A method for using an automatic unloading and loading device for aviation precision seamless pipes, using the above-mentioned automatic unloading and loading device for aviation precision seamless pipes, comprising the following steps:

[0015] Step 1: Stock up a large amount of pipes in the pipe storage area;

[0016] Step 2: According to the situation of this batch processing, select several pipes and put them in the pipe feeding area. The bottom pipe will fall into the semicircular concave tray of the straight pipe positioning push block of the feeding pushing mechanism due to gravity and inclination angle;

[0017] Step 3: Open the three-axis guide rod cylinder of the material unloading push mechanism, the bottom pipe will follow the straight pipe positioning push block to move to the end position, and the second to last pipe will be blocked by the end of the straight pipe positioning push block and the baffle of the pipe unloading area;

[0018] Step 4: Open the rotating cylinder in the flipping mechanism, drive the four flipping claws on the rotating spindle, move the pipe on the unloading pushing mechanism, and push it onto the load-bearing guide plate. The pipe will fall to the bottom of the V-groove on the load-bearing guide plate according to gravity;

[0019] Step 5: The diffuse reflection photoelectric sensor on the bearing guide plate in the blanking positioning mechanism determines the longest position signal of the pipe, and determines the original pipe length range according to the set distances of each sensor;

[0020] Step 6: The pneumatic gripper of the tube pushing mechanism will hold the tube, and the driving motor will drive the pneumatic gripper and the tube on it to send the tube to the diffuse reflection photoelectric sensor positioning point at the feeding origin along the linear guide rail;

[0021] Step 7: After the pipe reaches the feeding origin, the driving motor drives the pneumatic gripper back to the original position;

[0022] Step 8: According to the input pipe length, the pneumatic gripper first clamps the pipe, and the driving motor drives the pneumatic gripper and the pipe on it to output the specified length along the linear guide. The output length is calculated based on the output ratio of the output pulse of the servo drive motor and the stroke of the lead screw.

[0023] The beneficial effects of the present invention are:

[0024] Compared with the traditional technology, the present invention greatly reduces the overall footprint of the equipment, simplifies the mechanical structure of the equipment, realizes the automatic feeding function under the condition of a small number of driving mechanisms, reduces the equipment manufacturing cost, and the probability of failure.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0036] like Figure 1As shown, an automatic unloading and loading device for aviation precision seamless pipes includes a pipe storage area 1, a pipe unloading area 2, a unloading pushing mechanism 3, a flipping mechanism 4, a pipe pushing mechanism 5, a unloading positioning mechanism 6, a feeding origin position 7 and an industrial computer.

[0037] The pipe storage area 1 is used to store pipes 20. An observation adjustment slot is provided at the side end of the pipe storage area 1, so that an operator can check the number and approximate length information of the placed pipes 20.

[0038] The pipe material discharge area 2 is connected to the pipe material storage area 1, and the lower end is connected to the material discharge pushing mechanism 3 and the material discharge positioning mechanism 6. The maximum single load is thirty pipes 20 of irregular length. The pipe material discharge area 2 is as follows Figure 2 The opening width of the pipe material discharge area 2 is 1 to 1.25 times the diameter of a single pipe 20, ensuring that only one pipe 20 can be dropped into the trough at a time.

[0039] The material unloading pushing mechanism 3 is composed of a base plate bracket, a cylinder mounting plate, a straight tube positioning push block 10, and a three-axis guide rod cylinder 11. Figure 3 The cylinder mounting plate is arranged on the top of the base plate bracket, the three-axis guide rod cylinder 11 is arranged on the cylinder mounting plate, and the straight tube positioning push block 10 is connected to the three-axis guide rod cylinder 11.

[0040] Among them, the straight tube positioning push block 10 is provided with a semicircular recessed tray for supporting the tube 20. When the three-axis guide rod cylinder 11 is at the origin position during operation, the tube 20 at the bottom of the tube discharge area 2 will fall into the semicircular recessed tray on the straight tube positioning push block 10. The gap size between the upper end of the tube 20 and the bottom of the material plate in the tube discharge area 2 is smaller than the diameter size of a single tube 20, ensuring that the upper tube 20 will not fall. After the three-axis guide rod cylinder 11 pushes, the gap size between the rear upper end surface of the straight tube positioning push block 10 and the bottom of the material plate in the tube discharge area 2 is smaller than the diameter size of a single tube 20, thereby blocking the tube 20 in the tube discharge area 2 until the three-axis guide rod cylinder 11 returns to the origin position, and the tube 20 will fall into the semicircular recessed tray on the straight tube positioning push block 10, realizing a single feeding of one tube 20; when working, Figure 4 shown.

[0041] The flip mechanism 4 is composed of four flip claw hooks 12, a rotating main shaft 13, a rotating bracket 14, and a rotating cylinder 15. The rotating main shaft 13 and the rotating cylinder 15 are arranged on the rotating bracket 14, and the rotating cylinder 15 is coaxially connected with the rotating main shaft 13. The four flip claw hooks 12 are arranged on the rotating main shaft 13, and are used to move the pipe 20 on the blanking pushing mechanism 3 to the blanking positioning mechanism 6. Figure 5 shown.

[0042] The pipe pushing mechanism 5 is composed of a driving motor 16, a lead screw 17, a pneumatic clamp 18, and a linear guide 19. The lead screw 17 is connected to the driving motor 16, and the pneumatic clamp 18 is slidably mounted on the linear guide 19, and the pneumatic clamp 18 is connected to the lead screw 17. It is used to push the pipe 20 on the blanking positioning mechanism 6 to the feeding origin position 7. Figure 6 shown.

[0043] The material unloading positioning mechanism 6 is composed of five bearing guide plates 8 distributed in sequence along a straight line and five diffuse reflection photoelectric sensors 9 correspondingly arranged on the five bearing guide plates 8. Figure 7 As shown. The bearing guide plate 8 and the diffuse reflection photoelectric sensor 9 are as shown. Figure 8 After the pipe 20 is loaded, the original length of the pipe 20 is measured using the signal from the diffuse reflection photoelectric sensor 9 at the fixed position of the bearing guide plate 8.

[0044] A method for using an automatic unloading and loading device for aviation precision seamless pipes, using the above-mentioned automatic unloading and loading device for aviation precision seamless pipes, comprising the following steps:

[0045] Step 1: Stock a large amount of pipes 20 in the pipe storage area 1.

[0046] Step 2: According to the situation of this batch processing, select several pipes 20 and put them in the pipe discharge area 2. The bottom pipe 20 will fall into the semicircular recessed tray of the straight pipe positioning push block 10 of the material discharge pushing mechanism 3 due to gravity and the inclination angle.

[0047] Step 3: Open the three-axis guide rod cylinder 11 of the material discharge pushing mechanism 3, the bottom pipe 20 will follow the straight pipe positioning push block 10 to move to the end position, and the second to last pipe 20 will be blocked by the end of the straight pipe positioning push block 10 and the baffle of the pipe discharge area 2.

[0048] Step 4: Open the rotating cylinder 15 in the flipping mechanism 4, drive the four flipping claw hooks 12 on the rotating spindle 13, move the pipe 20 on the unloading pushing mechanism 3, and push it onto the load-bearing guide plate 8. The pipe 20 will fall to the bottom end of the V-groove on the load-bearing guide plate 8 according to gravity.

[0049] Step 5: The diffuse reflection photoelectric sensor 9 on the bearing guide plate 8 in the blanking positioning mechanism 6 determines the longest position signal of the pipe 20, and determines the original pipe length range according to the set distances of each sensor.

[0050] Step 6: The pneumatic clamp 18 of the tube pushing mechanism 5 will clamp the tube 20, and the driving motor 16 will drive the pneumatic clamp 18 and the tube 20 thereon to send the tube 20 to the positioning point of the diffuse reflection photoelectric sensor 9 at the feeding origin position 7 along the linear guide rail 19.

[0051] Step 7: After the pipe 20 reaches the feeding origin position 7, the driving motor 16 drives the pneumatic clamp 18 to return to the original position.

[0052] Step 8: According to the input length of the tube 20, the pneumatic clamp 18 first clamps the tube 20, and the driving motor 16 drives the pneumatic clamp 18 and the tube 20 thereon to output the specified length along the linear guide 19.
