Description

Technical Field

[0001] The utility model relates to the field of three-axis manipulators, in particular to a three-axis manipulator for lathe insertion. Background Art

[0002] In the production of automatic lathe parts, materials need to be transferred between the lathe and the silo to complete the loading and unloading operations. Currently, there are three-axis manipulators for loading and unloading materials, but the existing technology has the following shortcomings: 1. When transferring materials, the three-axis manipulator can only load and unload one material in one round trip from the lathe to the silo, which is relatively inefficient; 2. The existing three-axis manipulator uses a two-claw cylinder to grab materials for loading and unloading operations. During production, the two-claw cylinder clamps the edge of the material and aligns the material with the hole of the lathe to place the material into the hole for processing. In the process of the two-claw cylinder putting the material into the lathe or taking it out from the lathe, the clamping effect of the two-claw cylinder on the material conflicts with the storage effect of the hole of the lathe on the material, which can easily cause the material to shift or fall off, affecting the lathe's processing of the material or the three-axis manipulator's operation of taking the material out of the lathe; 3. The two-claw cylinder includes two claws, and the surface of the claw in contact with the material is made of metal. The material to be processed is also made of metal, and the material may be damaged during transfer. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, such as low efficiency, easy deviation or falling of materials during transfer, and easy damage of materials by two-claw cylinders, the purpose of the utility model is to provide a three-axis manipulator for lathe jacking.

[0004] The technical solution adopted by the utility model is as follows: a lathe top-entry three-axis manipulator includes a Z-axis component, an X-axis component driven by the Z-axis component, and a Y-axis component driven by the X-axis component;

[0006] The three-claw cylinder comprises three claws for grabbing materials, and a positioning portion for positioning the upper part of the material is provided between the three claws.

[0007] As a preferred embodiment of the utility model, a second mounting seat is provided at the end of the Y-axis assembly, and the second mounting seat has a second inclined surface with an angle less than ninety degrees with the ground. The rotating power source is installed on the second inclined surface, and the first mounting seat drives the three-claw cylinder to rotate on a third inclined surface parallel to the second inclined surface. The three-claw cylinder changes the direction of the three claws as the first mounting seat rotates.

[0008] As a preferred embodiment of the utility model, when the three-claw cylinder rotates to the highest point of the third inclined surface, the three claws face the vertical plane, and when the three-claw cylinder rotates to the lowest point of the third inclined surface, the three claws face the horizontal plane.

When the material is transferred by the three-axis manipulator, two materials can be grasped at the same time in one back and forth movement, thereby improving the processing efficiency; 2. A receiving groove for accommodating the upper part of the material is arranged between the three claws. In the process of putting the material into the lathe or taking it out from the lathe, the receiving groove can guide and limit the material, thereby reducing the occurrence of deviation or falling off; 3. The claws are made of silicone or soft rubber material, and the hardness of silicone or soft rubber is less than the hardness of the material. Therefore, the three-claw cylinder will not damage the material when transferring the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0017] In the description of the present application, the terms "first", "second", "end", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0018] The figure marks in the drawings of the specification include: Z-axis assembly 1, X-axis assembly 2, Y-axis assembly 3, removal fixture 4, rotation power source 401, first mounting seat 402, three-claw cylinder 403, hand claw 4031, receiving groove 4032, second mounting seat 404, chassis 5, shelf 501, silo 6.

[0019] The embodiment is basically as follows Figure 1 As shown: a three-axis manipulator is inserted into the lathe, including a chassis 5, an upper frame 501 installed on the top surface of the chassis 5, a Z-axis component 1 arranged on the upper frame 501, an X-axis component 2 driven by the Z-axis component 1, and a Y-axis component 3 driven by the X-axis component 2. Two silos 6 for placing materials are also provided on the top surface of the chassis 5. Both materials to be processed and materials that have been processed can be placed in the silos 6. When processing materials, the three-axis manipulator transfers the materials to be processed in one of the silos 6 to the lathe for processing, and puts the materials back into the silo 6 after the processing is completed, until all the materials in the silo 6 are processed, and then the three-axis manipulator repeats the above operation on the next silo 6. When the three-axis manipulator operates the next silo 6, the worker can remove the previous silo 6 and replace it with a third silo 6 containing materials to be processed, or replace the materials that have been processed in the previous silo 6 with materials to be processed. It is worth noting that the above-mentioned three-axis manipulator and the specific structures such as the Z-axis assembly 1, the X-axis assembly 2 and the Y-axis assembly 3 are all mature existing technologies and will not be repeated in this embodiment.

[0020] like Figure 2As shown, a removal jig 4 is provided at the end of the Y-axis assembly 3, and the removal jig 4 includes a rotary power source 401, a first mounting seat 402, a second mounting seat 404 and a plurality of three-claw cylinders 403. The first mounting seat 402 is provided at the output end of the rotary power source 401, and the first mounting seat 402 has a convex surface. A plurality of three-claw cylinders 403 are provided on the convex surface of the first mounting seat 402. The rotary power source 401 is used to drive the first mounting seat 402 and the three-claw cylinder 403 to rotate. Specifically, a second mounting seat 404 is provided at the end of the Y-axis assembly 3, and the second mounting seat 404 has a second inclined surface with an angle less than ninety degrees with the ground. The rotary power source 401 is installed on the second inclined surface, and the first mounting seat 402 drives the three-claw cylinder 403 to rotate on a third inclined surface parallel to the second inclined surface. The axis around which this rotation is carried out is in the same direction as the output axis of the rotary power source 401. The three-claw cylinder 403 changes the orientation of the three claws 4031 as the first mounting seat 402 rotates. In this embodiment, the hole of the lathe is perpendicular to the vertical plane, and the material in the silo 6 is placed horizontally. Therefore, when the three-claw cylinder 403 rotates to the highest point of the third inclined surface, the three claws 4031 face the vertical plane, so that the three-claw cylinder 403 can place the material to be processed into the hole of the lathe for processing, or remove the processed material from the lathe; when the three-claw cylinder 403 rotates to the lowest point of the third inclined surface, the three claws 4031 face the horizontal plane, so that the three-claw cylinder 403 can take out the material to be processed from the silo 6, or place the processed material into the silo 6.

[0021] Furthermore, the first mounting seat 402 is in the shape of a triangular prism, with rounded corners on the side of the triangular prism, two three-claw cylinders 403, the rotary power source 401 is a rotary cylinder, one side of the first mounting seat 402 is connected to the output end of the rotary power source 401, the other two sides of the first mounting seat 402 are convex surfaces of the first mounting seat 402, and the two three-claw cylinders 403 are respectively mounted on the other two sides of the first mounting seat 402. In addition, the three-claw cylinder 403 includes a cylinder body, and three claws 4031 for grabbing materials on a side of the cylinder body away from the first mounting seat 402, the claws 4031 are made of silicone or soft rubber, and between the three claws 4031, that is, on the surface of the cylinder body where the claws 4031 are set, there are positioning parts for positioning the upper part of the material, that is, a receiving groove 4032 that can accommodate the upper part of the material. In the process of transferring the material, the receiving groove 4032 can accommodate the upper part of the material, thereby guiding and limiting the material.

[0022] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
