Description

Technical Field

[0001] The invention belongs to the technical field of tool loading and unloading conveyors, in particular to a tool loading and unloading conveyor for large machine tools. Background Art

[0002] Machine tools are mechanical equipment used to process metal, non-metal and other materials. Through mechanical cutting, grinding, stamping and other processes, the required parts and products are manufactured. Machine tools play a vital role in modern manufacturing and are widely used in automobile, aviation, mold, machinery manufacturing and other industries. Large machine tools are equipment used to process large-size workpieces, usually for high-precision metal processing, and are widely used in aerospace, shipbuilding, automobile industry, mold manufacturing and heavy machinery. There are many types of tools used on large machine tools. Different tools are mainly selected according to the processing type, material and shape of the workpiece. Tool loading and unloading transporters are important equipment for machine tool tool management and replacement, especially in large machine tools and automated production. Tools are tools used for cutting, shaving, forming or processing materials (usually metal, plastic, wood, etc.). According to the purpose of use and materials, tools can be divided into many types. Tools play a vital role in modern industry and production. Reasonable selection and use of tools can significantly improve production efficiency and processing quality.

[0003] Existing loading and unloading technology uses a crane to load and unload the tool. During loading and unloading, the tool will shake with the crane, and the installation position cannot be accurately located. During disassembly, if the tool and the crane are not fixed firmly enough, the tool will fall. The falling tool may damage the tool holder, fixture or other related parts of the machine tool, resulting in increased maintenance costs. The fallen tool may hit other equipment or personnel, leading to a wider risk of injury. When clamping, the tool surface will be worn. Wear is one of the main causes of tool failure.

[0028] 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 explained below in conjunction with specific implementation methods.

[0029] Reference Figure 1 - Figure 7 , the present invention provides two technical solutions:

[0030] Embodiment 1:

[0031] It includes a support base 1, the inner side wall of the support base 1 is fixedly connected with a connecting plate 2, the upper surface of the connecting plate 2 is fixedly connected with a clamping mechanism, the outer surface of the clamping mechanism is fixedly connected with an adsorption mechanism, and both sides of the bottom of the support base 1 are fixedly connected with a scissor-type lifting mechanism;

[0032] The adsorption mechanism includes a connecting disk 3, a connecting rod 4 is fixedly connected to the middle of the connecting disk 3, one end of the connecting rod 4 is hinged to a vacuum suction plate A 5 through a connecting shaft, the bottom of the vacuum suction plate A 5 is fixedly connected to a base plate 6, and the bottom of the base plate 6 is fixedly connected to a suction cup A 7 on all sides, both sides of the connecting disk 3 are fixedly connected to limiting rods 8, both sides of the base plate 6 are provided with grooves, the inside of the grooves are inserted into the outer surface of the limiting rod 8, the surface of the connecting disk 3 is fixedly connected to a micro electric push rod 9, and one end of the micro electric push rod 9 is fixedly screwed to the surface of the vacuum suction plate A 5.

[0033] The tool body of a large machine tool is relatively large. During loading and unloading, the tool needs to be clamped and fixed by an external clamping mechanism, and then the connection part is disassembled by personnel. The adsorption mechanism can be used to vacuum the contact surface between the surface of the adsorption mechanism and the tool to achieve the effect of vacuum adsorption. The adsorption mechanism can firmly clamp the tool and reduce the risk of the tool falling, thereby ensuring the safety of the operator. Vacuum adsorption can provide a strong clamping force, which can keep the workpiece stable even under high load conditions and prevent the tool from slipping or falling. Traditional mechanical fixtures may cause scratches or dents on the workpiece surface during the clamping process, while vacuum adsorption effectively avoids this problem through a larger contact area.

[0034] Embodiment 2:

[0035] Based on Example 1:

[0036] The clamping mechanism includes a clamping fixed plate 10, and A springs 11 are symmetrically arranged on both sides of the clamping fixed plate 10. One end of the A spring 11 is fixedly connected to a pulling plate 12, and the bottom of the pulling plate 12 is rotatably connected to a support plate 13 through an A rotating shaft. The middle part of the pulling plate 12 is rotatably connected to a connecting plate 14 through a B rotating shaft, and one side of the connecting plate 14 is rotatably connected to a lifting plate 15 through a C rotating shaft. The bottom of the lifting plate 15 is fixedly connected to an A electric push rod 16, and the bottom of the A electric push rod 16 is fixedly connected to the upper surface of the connecting plate 2.

[0037] A rotating part 17 is symmetrically arranged on both sides of the upper surface of the connecting plate 14, one end of the A rotating part 17 is fixedly connected to the B spring 18, one end of the B spring 18 is fixedly connected to the B rotating part 19, one end of the B rotating part 19 is fixedly connected to the inner wall of the pulling plate 12. When the tool is clamped and fixed by the clamping mechanism, the B spring 18 and the A electric push rod 16 are arranged inside the clamping mechanism. The B spring 18 can adaptively provide corresponding clamping force according to the shape and size of the workpiece to effectively maintain the stability of the workpiece. The A electric push rod 16 can adjust the clamping force as needed. The cooperation of the two can achieve a more uniform clamping force distribution and reduce the risk of deformation and damage of the workpiece.

[0038] The scissor-type lifting mechanism includes an A rotating rod 20, both ends of the outer surface of the A rotating rod 20 are rotatably connected to the A lifting rod 21, the middle part of the A lifting rod 21 is rotatably connected to the B lifting rod 22 through the A rotating block, the other end of the A lifting rod 21 is rotatably connected to the B rotating rod 23, the middle part of the outer surface of the A rotating rod 20 is fixedly connected to the C rotating member 24, one end of the C rotating member 24 is fixedly connected to the B electric push rod 25, and one end of the B electric push rod 25 is fixedly connected to the D rotating member 26. When the support seat 1 is lifted by the scissor-type lifting mechanism, the structural design of the scissor-type lifting mechanism keeps it stable during the lifting process, reduces the risk of lateral swing and tilt, ensures the safety of the support seat 1, reduces the shaking during loading and unloading, and quickly loads and unloads the tool.

[0039] There are two groups of A lifting rods 21 and B lifting rods 22, one end of each group of A lifting rods 21 and B lifting rods 22 is fixedly connected to a fixing block 27. When the A lifting rods 21 and B lifting rods 22 use the fixing block 27 to drive the support seat 1 upward at the same time, the stability can be increased and the shaking during lifting can be reduced, which will cause inaccurate positioning and affect the loading and unloading of the tool.

[0040] A storage box 28 is fixedly connected to the outer surface of the A rotating rod 20, and leaking plates are fixedly connected to both sides of the upper surface of the storage box 28. The storage box 28 facilitates the folding of the scissor-type lifting mechanism and plays a storage role.

[0041] An extension plate 29 is fixedly connected to one side of the storage box 28, and a fixedly installed B vacuum suction plate 30 is opened in the middle of the extension plate 29. The bottom of the B vacuum suction plate 30 is fixedly connected to an air storage disk 31, and the bottom of the air storage disk 31 is fixedly connected to a B suction cup 32. Before clamping the tool, in order to prevent the support seat 1 from sliding due to the moving wheels 33 and affecting the loading and unloading of the tool, the B suction cup 32 is placed close to the ground, the B vacuum suction plate 30 is started, and air is pumped in the air storage disk 31 to achieve a vacuum adsorption effect between the B suction cup 32 and the ground, thereby increasing stability.

[0042] The bottom of the storage box 28 and the extension plate 29 are fixedly connected with moving wheels 33, and the outer surface of the moving wheels 33 is fixedly connected with rubber sleeves. The moving wheels 33 play a role of movement. Adding rubber sleeves on the outer surface of the moving wheels 33 can increase friction and play an anti-slip role.

[0043] Working principle: When loading and unloading tools, start the B electric push rod 25. When the B electric push rod 25 is extended and retracted to the left and right, the angle is adjusted by the C rotating member 24 and the D rotating member 26 to facilitate the rotation angle when the B electric push rod 25 is raised or lowered. Then, the B electric push rod 25 drives the B rotating rod 23 upward, and the B rotating rod 23 drives the A lifting rod 21 and the B lifting rod 22 to cross-lift and lower. The fixed blocks 27 on the A lifting rod 21 and the B lifting rod 22 are used to lift the support seat 1 upward to a suitable height. Then, before clamping the tool, in order to prevent the support seat 1 from sliding due to the moving wheel 33 and affecting the loading and unloading of the tool, the B suction cup 32 is pressed against the ground , start the B vacuum suction plate 30, extract air in the air storage disc 31, and achieve the effect of vacuum adsorption between the B suction cup 32 and the ground to increase stability. Then, start the A electric push rod 16, which drives the lifting plate 15 to move up and down. The lifting plate 15 pulls the connecting piece 14 downward through the C rotating shaft, and the connecting piece 14 drives the pulling plate 12 to clamp inward through the B rotating shaft. When clamping, the pulling plate 12 squeezes the B spring 18 through the A rotating member 17, and the B spring 18 drives the B rotating member 19 to squeeze on the connecting piece 14. The B spring 18 can provide corresponding clamping force according to the shape and size of the workpiece, effectively ensuring To ensure the stability of the workpiece, the A electric push rod 16 can adjust the clamping force as needed. The combination of the two can achieve a more uniform clamping force distribution and reduce the risk of deformation and damage to the workpiece. Then, when clamped to a certain angle, the clamping mechanism will drive the adsorption mechanism to stick to the surface of the tool, and use the A suction cup 7 to stick to the tool. In order to adapt to the shape of the tool, the micro electric push rod 9 is started. The micro electric push rod 9 drives the A vacuum suction plate 5, the bottom plate 6 and the A suction cup 7 to tilt to an angle that is more in line with the tool. When the micro electric push rod 9 tilts left and right, the limit rod 8 is used to increase the limit to avoid excessive tilting of the angle. Then, the fit is complete. After completion, start the A vacuum suction plate 5, and the A vacuum suction plate 5 drives the A suction cup 7 to perform vacuum adsorption on the contact surface of the tool, so that the adsorption mechanism is used to perform vacuum adsorption while clamping. Vacuum adsorption can provide strong clamping force, and can keep the workpiece stable even under high load conditions to prevent the tool from sliding or falling. Traditional mechanical clamps may cause scratches or dents on the workpiece surface during the clamping process, while vacuum adsorption effectively avoids this problem through a large contact area, ensuring the integrity of the tool surface. After clamping and positioning, the personnel manually loosen or install the bolts at the connection parts to complete the loading and unloading of the tool.
