DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: an automatic telescopic mechanism for a machine tool that is easy to disassemble, comprising a base frame 1, rectangular slide grooves 22 are symmetrically provided on both sides of the top of the base frame 1, and limiting slide bars 4 are symmetrically fixedly installed on both sides inside the base frame 1, and a conveying screw 5 is rotatably installed between two groups of limiting slide bars 4 inside the base frame 1, and the surfaces of the two groups of limiting slide bars 4 and the conveying screw 5 are slidably connected with a moving seat 6. By providing the limiting slide bars 4, when the moving seat 6 is controlled to move on the surfaces of the two groups of limiting slide bars 4, it is ensured that the moving seat 6 will not tilt during the movement.

[0023] A rotating motor 2 is fixedly installed on one side of the base frame 1, and a bevel gear 3 is fixedly installed on the output end of the rotating motor 2. The end of the conveying screw 5 close to the rotating motor 2 passes through the base frame 1 and is fixedly installed with a bevel gear 3. The two sets of bevel gears 3 are meshed with each other. Because the rotating motor 2 is provided, the rotating motor 2 is controlled to rotate forward and reverse, thereby driving the conveying screw 5 to rotate synchronously, so that the moving seat 6 can reciprocate on the surface of the conveying screw 5.

[0024] A moving seat 6 is provided at the top of the base frame 1, and mounting frames 8 are symmetrically fixedly installed on both sides of the moving seat 6. Multiple sets of mounting shafts 9 are fixedly installed at equal intervals inside the mounting frame 8, and rollers 10 are rotatably installed on the surfaces of the mounting shafts 9, and the rollers 10 correspond to the rectangular slide grooves 22. By providing the rollers 10, the moving seat 6 drives the mounting frame 8 to move on the top of the base frame 1, and the rollers 10 roll inside the rectangular slide grooves 22, thereby reducing the friction of the mounting frame 8 when it moves on the top of the base frame 1.

[0025] A baffle 7 is fixedly installed on one side of the top of the moving seat 6. Because of the baffle 7, when the telescopic ejector seat 20 is placed on the top of the moving seat 6 and close to the baffle 7, the baffle 7 blocks and limits the telescopic ejector seat 20;

[0026] A telescopic ejector seat 20 is provided on the top of the movable seat 6, and three groups of fixed sockets 21 are equidistantly provided at the bottoms on both sides of the telescopic ejector seat 20, and the fixed sockets 21 correspond to the fixed plug rods 14. Because the fixed sockets 21 are provided, after the telescopic ejector seat 20 is placed on the top of the movable seat 6 and the fixed plug rods 14 are inserted into the corresponding fixed sockets 21, it is ensured that the telescopic ejector seat 20 is clamped and fixed on the top of the movable seat 6.

[0027] Three sets of mounting seats 11 are fixedly installed at equal distances on both sides of the top of the moving seat 6, and a mounting groove 12 is provided at one end of the mounting seat 11, and a limiting slide groove 13 is provided at one end of the mounting groove 12 inside the mounting seat 11. Due to the limiting slide groove 13, the dragging connecting plate 17 drives the fixed plug rod 14 to slide inside the mounting groove 12 and the limiting slide groove 13, thereby limiting the moving distance of the fixed plug rod 14;

[0028] A fixed plug rod 14 is slidably installed inside the installation groove 12, and one end of the fixed plug rod 14 away from the limiting slide groove 13 passes through the installation groove 12 and extends to the outside of the installation seat 11. A limiting plate 15 is fixedly installed on the surface of the fixed plug rod 14 located inside the installation groove 12 away from the limiting slide groove 13, and a fixing spring 16 is provided on the surface of the fixed plug rod 14 located inside the installation groove 12. By providing the fixing spring 16, the limiting plate 15 is pushed toward the side of the installation groove 12 away from the limiting slide groove 13 under the rebound action of the fixing spring 16, so that the fixed plug rod 14 can be pushed out of the installation groove 12 and inserted into the corresponding fixed socket 21;

[0029] One end of the three groups of fixed rods 14 located inside the limiting slide groove 13 extends to the top of the mounting seat 11 and is fixedly installed with a connecting plate 17. Because of the connecting plate 17, the connecting plate 17 can be dragged to drive the three groups of fixed rods 14 to move synchronously.

[0030] Two groups of fixing bolts 18 are provided at the top of the connecting plate 17 between two adjacent groups of mounting seats 11, and two groups of positioning screw holes 19 are provided at the top of the moving seat 6 between two adjacent groups of mounting seats 11, and the positioning screw holes 19 correspond to the fixing bolts 18. By providing the fixing bolts 18, the fixing bolts 18 are screwed through the connecting plate 17 and inserted into the corresponding positioning screw holes 19, so that the position of the connecting plate 17 at the top of the moving seat 6 and the mounting seat 11 is clamped and fixed, ensuring that the fixed plug rod 14 will not slide freely inside the mounting groove 12.

[0031] The working principle of the utility model is:

[0032] Loosen the fixing bolts 18 and push the connecting plate 17 to both sides to drive the fixed plug rod 14 to retract into the corresponding mounting groove 12, place the telescopic ejector seat 20 on the top of the moving seat 6 and close to the baffle 7 to ensure that the fixed plug rod 14 corresponds to the fixed socket 21, loosen the connecting plate 17 and push the fixed plug rod 14 out of the mounting groove 12 and insert it into the corresponding fixed socket 21 under the rebound action of the fixing spring 16, then tighten the fixing bolts 18 to clamp and fix the connecting plate 17 on the top of the moving seat 6, and control the rotating motor 2 to rotate according to processing needs, so that the conveying screw 5 can control the moving seat 6 to slide on the surface of the limiting slide bar 4, drive the telescopic ejector seat 20 to approach the processing position of the machine tool parts, so that the telescopic ejector seat 20 can be pressed against one end of the part to clamp and fix the processed parts.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
