Technical Field

[0001] This utility model relates to the technical field of machine tool feeding devices, and in particular to a linkage-type multi-station machine tool feeding device. Background Technology

[0002] With the rapid development of modern manufacturing, people have put forward increasingly higher requirements for the precision, surface quality and production efficiency of parts. As the core equipment in mechanical manufacturing, machine tools have been widely used in processing.

[0003] In enterprise production, for mass-produced parts, once the machine tool program is written, only loading and unloading operations need to be completed. Currently, most loading and unloading operations are still done manually. However, the repetitive loading and unloading operations are monotonous, labor-intensive, and require a long waiting time, which consumes human resources and increases production costs. In the face of market competition, this is very detrimental to the development of enterprises. Utility Model Content

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific implementation method one: Combining Figure 1-7 As shown, the linkage multi-station machine tool feeding device includes: a frame 1, a slide table 2, and a gripper 3; a transverse rail 4 is provided above the frame 1; the slide table 2 is slidably connected to the transverse rail 4 and can be displaced in the horizontal direction; a vertical arm assembly 5 that can be displaced in the vertical direction is provided on the slide table 2; the gripper 3 is connected to the bottom end of the vertical arm assembly 5; the gripper 3 has two relatively arranged gripping positions, which correspond to loading or unloading respectively, and the two can be rotated 180 degrees to exchange positions.

[0028] Preferred embodiments, in combination Figure 2As shown, the transverse track 4 includes a crossbeam 401, a first slide block 402, and a first motor 403. Two first slide rails 404 are symmetrically arranged on the crossbeam 401. Each first slide rail 404 is formed by multiple slide rails laid sequentially. The crossbeam 401 is fixed to the platform 1 by bolts. A first rack 405 is located in the middle area of ​​the two first slide rails 404, and the first rack 405 is also formed by multiple slide rails spliced ​​sequentially. The first slide blocks 402 are installed in pairs on the back of the slide table 2, and at least two sets are used to improve the stability after connection. The first slide blocks 402 and the first slide rails 404 are slidably connected. The first motor 403 is fixedly connected to the slide table 2 and is connected to the first rack 405 by gear meshing. When lateral displacement is required, the first motor 403 drives the gear to rotate, driving the overall structure on the slide table 2 to move laterally, thus completing the horizontal position adjustment of the gripper.

[0029] Preferred embodiments, in combination Figure 3-5 As shown, a second motor 201 is provided above the slide table 2, and a gear is installed on the second motor 201; the vertical arm assembly 5 includes a vertical frame 501 and a second slide block 502; a second rack 503 connected to the second motor 201 is provided on the left side of the vertical frame 501, and a second slide rail 504 is symmetrically arranged behind the vertical frame 501. The second slide rail 504 can also adopt a slide rail structure; the second slide blocks 502 are installed in pairs on the slide table 2 and form a sliding connection with the second slide rail 504; by driving the vertical frame 501 to move by the second motor 201, the position adjustment of the gripper 3 in the height direction can be realized.

[0030] In a preferred embodiment, the vertical frame 501 can adopt a hollow structure design, which reduces its own weight and improves the flexibility during adjustment. On the other hand, the hollow structure facilitates the internal wiring for connection with the gripping component 3.

[0031] Preferred embodiments, in combination Figure 5-7 As shown, the gripper 3 includes a rotating component 301 and a three-jaw chuck 302. The rotating component 301 is fixedly installed at the bottom end of the vertical frame 501, and a support plate 303 is provided on the rotating component 301. The two three-jaw chucks 302 are fixed on the support plate 303 at a distance from each other. The position of the two three-jaw chucks 302 can be adjusted by rotating the support plate 303 180 degrees through the rotating component 301. The rotating component 301 can be an electric motor, a rotary cylinder, or a rotary hydraulic cylinder, and the three-jaw chucks 302 can also be electrically driven to achieve clamping or releasing operations.

[0032] Preferred embodiments, in combination Figure 6As shown, one of the three-jaw chucks 302 is provided with an annular plate 304, which has multiple sliding holes. The shrinking member 6 is inserted into the sliding holes to form a sliding connection. By relying on the shrinking member 6, the cylindrical blank can be pushed into the bottom of the machine tool chuck during the loading process of the CNC machine tool, ensuring the reliability of the installation position. After it is in place, the shrinking member 6 is triggered to perform compression displacement, which can reduce the accuracy requirements for lateral displacement.

[0033] Preferred embodiments, in combination Figure 6 and Figure 7 As shown, the retractable component 6 includes a triangular frame 601 and a spring 602; the three top positions of the triangular frame 601 are respectively provided with slide rods 603 connected to the annular plate 304, and the ends of the slide rods 603 are equipped with stop nuts for positioning, and each slide rod 603 is fitted with a spring 602 for supporting the triangular frame 601. The structural design of the triangular frame 601 meets the installation requirements of the three-jaw chuck 302 without interference, and ensures the strength and stability of the structure itself.

[0034] Preferred embodiments, in combination Figure 7 As shown, a push plate 604 is provided at the center of the triangular frame 601 to increase the contact area with the blank and improve the stability during pushing.

[0035] Both the first motor 403 and the second motor 201 can be geared motors.

[0036] Working Principle: The entire device is installed inside the factory. The left side of the horizontal track 4 is located above the CNC machine tool, and the right side is located in the raw material area. During operation, the slide table is located on the right side of the horizontal track 4, and the height of the three-jaw chuck 302 is adjusted by the vertical arm assembly 5. After a certain horizontal displacement, the raw material is gripped. Then, it is horizontally reset, causing the three-jaw chuck 302 to rise. The entire device then moves to the left along the horizontal track 4 to the position of the CNC machine tool. If the machine tool chuck has a finished product, the idle three-jaw chuck 302 is lowered to a specified height. After a certain horizontal displacement, it is gripped and reset. Then, the rotating part 301 drives the two three-jaw chucks 302 to switch positions, load the raw material, and then the entire device is reset to the right side of the horizontal track 4. The finished product is placed down, and a new raw material is clamped for use. The entire process requires no manual intervention. Through programming design, combined with PLC, sensors, and other controls, it can operate automatically, or it can be started and stopped manually, greatly reducing labor intensity, lowering enterprise production costs, and improving competitiveness.

[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
