Description

Technical Field

[0001] This invention relates to the field of horizontal machining center technology, and more particularly to the tool magazine door structure of horizontal machining centers. Background Technology

[0002] A horizontal machining center is a CNC machine tool with a horizontal spindle. It is mainly used in the machining industry, such as automobile manufacturing, machine tool manufacturing, and mold making. It can complete the machining of small and medium-sized housings, valve bodies, and various complex parts. Its structure typically includes three linear motion axes (X, Y, Z) and an optional fourth rotary axis (A-axis), making it suitable for machining small and medium-sized housings, valve bodies, and various complex parts.

[0003] Chinese patent publication number CN216781192U discloses a tool magazine door structure for a horizontal machining center, including a tool magazine, a protective door, and a door structure. The door structure is mounted on the tool magazine, and the protective door is mounted on the door structure. The door structure includes a moving component, a buffer component, and a locking component. The moving component, buffer component, and locking component are all mounted on the tool magazine. This design allows the tool magazine door to open and close in a sliding mode, saving space and reducing the impact force when closing, thus protecting the door. It also locks the door when closed, reducing the chance of accidental opening. However, this traditional tool magazine door requires a large opening for each tool change, which is time-consuming and allows cutting fluid, oil mist, dust, and metal shavings to easily enter the tool magazine, leading to accelerated tool wear, reduced spindle accuracy, and tool magazine mechanism jamming.

[0004] In view of this, the present invention proposes a tool magazine door structure for horizontal machining centers to solve the problems existing in the prior art. Summary of the Invention

Detailed Implementation

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 The horizontal machining center tool magazine door structure includes a tool magazine door 1. One end of the tool magazine door 1 is a semi-circular end 21, and a deflection cavity 22 is provided in the semi-circular end 21. Arc-shaped grooves 5, communicating with the deflection cavity 22, are evenly spaced on the outer wall of the semi-circular end 21. A connecting plate 25 is slidably connected to each arc-shaped groove 5. A fixed column 19 is fixedly connected inside the deflection cavity 22, and multiple rotating sleeves 23 are rotatably connected to the surface of the fixed column 19 at equal intervals. One end of each connecting plate 25 is fixedly connected to one side of the outer wall of the corresponding rotating sleeve 23, and the other end of each connecting plate 25 is fixedly connected to a secondary tool magazine door 6. The outer wall of the secondary tool magazine door 6 connected to the connecting plate 25 is an arc-shaped surface 26, and the arc-shaped surface 26 is tightly attached to and slidably connected to the outer wall of the semi-circular end 21. A toggle plate 24 is fixedly connected to the other side of the outer wall of each rotating sleeve 23. A deflection mechanism is provided on one side of the outer wall of the tool magazine door 1, and the deflection mechanism passes through various... The actuating plate 24 can deflect the secondary tool magazine door 6 from bottom to top. When a tool change is required, the tool changing mechanism in the tool magazine will be activated. At the same time, the deflection mechanism on the tool magazine door 1 will also be activated. The deflection mechanism applies force to the actuating plate 24 on the rotating sleeve 23 from bottom to top, causing the rotating sleeve 23 to rotate. This causes the connecting plate 25 on its outer wall to deflect along the arc groove 5. The deflection center of the connecting plate 25 is the center of the semi-circular end 21. Because the arc surface 26 of the secondary tool magazine door 6 is in close contact with and slidably connected to the outer wall of the semi-circular end 21, the connecting plate 25 can deflect the secondary tool magazine door 6 synchronously, allowing the secondary tool magazine door 6 to open from bottom to top. This can greatly limit the path of contaminants entering the tool magazine, creating a relatively clean environment for the tools and the inside of the tool magazine. This avoids the situation where cutting fluid, oil mist, dust, and metal shavings enter the tool magazine and contaminate the tools when the tool magazine is opened as a whole.

[0028] Reference Figure 1 and Figure 3 As a further embodiment of the present invention, the deflection mechanism includes an air pump 2, which is fixed to the outer wall of the tool magazine door 1. The air pump 2 is provided with a pipe 3, and multiple branch pipes 13 are connected at equal intervals on the pipe 3. Multiple air collection boxes 4 are embedded at equal intervals on the deflection cavity 22, and piston plates 15 are slidably connected inside each air collection box 4. The air pump 2 can switch between two states: air pumping and air extraction. When changing tools, the air pump 2 switches to the air pumping state, and at this time, the air pump 2 inputs gas into the pipe 3.

[0029] Reference Figure 3 and Figure 4As a further embodiment of the present invention, a connecting spring 14 is fixedly connected between the piston plate 15 and the inner wall of the deflection cavity 22. A push plate 16 is slidably connected to one side of the gas collection box 4, and one end of the push plate 16 is in contact with the outer wall of the corresponding actuating plate 24. One end of each branch pipe 13 is connected to the other side of the gas collection box 4, so that the gas collection box 4 can be filled with gas from bottom to top through the branch pipe 13 on its outer wall. As the gas collection box 4 is gradually filled with gas, the length of the push plate 16 extending out of the gas collection box 4 will become longer and longer. Since one end of the push plate 16 is in contact with the outer wall of the corresponding actuating plate 24, the rotating sleeve 23 is rotated by the actuating plate 24. If the tool magazine needs to be resealed after the tool change is completed, the air pump 2 switches to the suction state, so that the gas in the gas collection box 4 can be extracted from bottom to top, so that each auxiliary tool magazine door 6 is reset from bottom to top, thereby resealing the tool magazine.

[0030] Reference Figure 4 and Figure 6 As a further embodiment of the present invention, a reset cavity 28 is provided on one side of the rotating sleeve 23, and a traction rope 18 is slidably connected at the connection between the reset cavity 28 and the deflection cavity 22, and a guide post 17 is fixedly connected to the inner wall of the deflection cavity 22.

[0031] Reference Figure 4 and Figure 6 As a further embodiment of the present invention, the inner wall of the reset cavity 28 is slidably connected with a slide plate 27, and a reset spring 29 is fixedly connected between the slide plate 27 and the inner wall of the reset cavity 28. One end of the traction rope 18 is fixedly connected to the outer wall of the slide plate 27, and the other end of the traction rope 18 passes through the guide post 17 and is fixedly connected to the actuating plate 24. When the push plate 16 pushes the actuating plate 24 to rotate the rotating sleeve 23, the actuating plate 24 can pull the slide plate 27 to move through the traction rope 18, and the reset spring 29 will be compressed. When the air pump 2 draws air, the push plate 16 will retract into the air collection box 4. Under the action of the rebound force of the reset spring 29, the secondary knife magazine door 6 can be reset through the traction rope 18.

[0032] Working principle: When a tool change is required, the tool changing mechanism in the tool magazine will be activated. At the same time, the deflection mechanism on the tool magazine door 1 will also be activated. The air pump 2 in the deflection mechanism will switch to air pumping mode. At this time, the air pump 2 will input gas into the pipe 3, so that the gas collection box 4 can be filled with gas from bottom to top through the branch pipe 13 on its outer wall. As the gas collection box 4 is gradually filled with gas, the length of the push plate 16 extending out of the gas collection box 4 will become longer and longer. Since one end of the push plate 16 is in contact with the outer wall of the corresponding actuating plate 24, the actuating plate 24 will cause the rotating sleeve 23 to rotate, thereby causing the connecting plate 25 on its outer wall to deflect along the arc groove 5. The deflection center of the connecting plate 25 is the center of the semi-circular end 21. Because the arc-shaped surface 26 of the secondary tool magazine door 6 is in close contact with and slidably connected to the outer wall of the semi-circular end 21, the connecting plate 25 can rotate synchronously with the secondary tool magazine door 6. Through the above operation, the secondary tool magazine doors 6 can be opened sequentially from bottom to top, which can greatly limit the path of contaminants entering the tool magazine and create a relatively clean environment for the tool and the inside of the tool magazine. This avoids the situation in the past where cutting fluid, oil mist, dust and metal shavings entered the tool magazine and contaminated the tool when the tool magazine was opened as a whole. If the tool magazine needs to be sealed again after the tool change is completed, the air pump 2 switches from the air pumping state to the air extraction state, so that the gas in the air collection box 4 can be extracted sequentially from bottom to top, so that each secondary tool magazine door 6 can be reset sequentially from bottom to top, thereby sealing the tool magazine again.

[0033] Reference Figure 7 As a further embodiment of the present invention, a sealing drive cavity 33 is provided above each arc-shaped groove 5, and an electromagnet 32 ​​is provided on the inner wall of the top of the sealing drive cavity 33. A magnetic plate 35 is slidably connected to the inner wall of the sealing drive cavity 33, and multiple connecting springs 34 are fixedly connected between the electromagnet 32 ​​and the magnetic plate 35. When the deflection mechanism can deflect the secondary knife magazine door 6 from bottom to top in sequence through each actuating plate 24, the electromagnets 32 in each sealing drive cavity 33 are energized from bottom to top in sequence. The magnetic force generated by the electromagnet 32 ​​after being energized attracts the magnetic plate 35, which can make the magnetic plate 35 move upward.

[0034] Reference Figure 7As a further embodiment of the present invention, a connecting cavity 30 connects the sealed driving cavity 33 and the arc-shaped groove 5. An arc-shaped sealing plate 31 is slidably connected inside the connecting cavity 30, and the top of the arc-shaped sealing plate 31 is fixedly connected to the magnetic plate 35. When the deflection mechanism is not activated, the electromagnets 32 are not energized. Under the elastic force of the connecting spring 34, the arc-shaped sealing plates 31 can seal each other from the 5, thereby preventing waste chips, cutting fluid, etc. generated during processing from entering the arc-shaped groove 5. When the electromagnets 32 are energized... After the power is applied, the magnetic plate 35 will move upward with the arc-shaped sealing plate 31 until the bottom end of the arc-shaped sealing plate 31 enters the connecting cavity 30, causing the arc-shaped groove 5 to open. At this time, driven by the deflection mechanism, the connecting plate 25 in the arc-shaped groove 5 will deflect the secondary tool magazine door 6 along the arc-shaped groove 5. Then, the electromagnet 35 in the sealing drive cavity 33 above the arc-shaped groove 5 will be de-energized. Thus, after the tool change is completed and each secondary tool magazine door 6 is reset, the arc-shaped sealing plate 31 will reseal the arc-shaped groove 5 under the action of the connecting spring 2 34.

[0035] Reference Figure 2 As a further embodiment of the present invention, an air pump 2 11 is provided on the other side of the blade magazine door 1, and a threaded rod 8 is provided on one side of the air pump 2 11. A rotary motor 12 is provided at the top of the threaded rod 8, and a threaded slider 7 is threadedly connected to the outer wall of the threaded rod 8. When the deflection mechanism can deflect the secondary blade magazine door 6 from bottom to top in sequence through each actuating plate 24, the rotary motor 12 causes the threaded rod 8 to rotate, causing the threaded slider 7 on its outer wall to move upward. At the same time, the air pump 2 11 is started.

[0036] Reference Figure 2 and Figure 4 As a further embodiment of the present invention, an air outlet pipe 9 is installed in the threaded slider 7, and a hose 10 is provided between one end of the air outlet pipe 9 and the second air pump 11. Multiple air nozzles 20 are arranged at equal intervals on the outer wall of the air outlet pipe 9 facing the secondary tool magazine door 6. Gas is input into the air outlet pipe 9 through the hose 10, and then the gas in the air outlet pipe 9 is ejected through the multiple air nozzles 20. Thus, when each secondary tool magazine door 6 is deflected from bottom to top, the airflow ejected by the air nozzles will blow out slightly, effectively preventing external contaminants from entering.

[0037] Working principle: When the deflection mechanism is not activated, the electromagnets 32 are not energized. Under the elastic force of the connecting spring 34, the arc-shaped sealing plates 31 can seal each other from 5, thereby preventing waste chips, cutting fluid, etc. generated during processing from entering the arc-shaped groove 5. When the deflection mechanism can deflect the secondary tool magazine door 6 from bottom to top through the actuating plates 24, the electromagnets 32 in the sealed drive cavities 33 are energized from bottom to top. The magnetic force generated by the energized electromagnets 32 attracts the magnetic plate 35, which can make the magnetic plate 35 attract the magnetic plate 35. As plate 35 moves upward, magnetic plate 35 will move arc-shaped sealing plate 31 upward until the bottom end of arc-shaped sealing plate 31 enters the connecting cavity 30, causing arc-shaped groove 5 to open. At this time, driven by the deflection mechanism, connecting plate 25 in arc-shaped groove 5 will deflect the secondary tool magazine door 6 along arc-shaped groove 5. Then, electromagnet 35 in sealing drive cavity 33 above arc-shaped groove 5 is de-energized. Thus, after tool changing is completed and each secondary tool magazine door 6 is reset, arc-shaped sealing plate 31 re-seals arc-shaped groove 5 under the action of connecting spring 2 34.

[0038] When the deflection mechanism can deflect the secondary tool magazine door 6 from bottom to top sequentially through the various actuating plates 24, the rotary motor 12 causes the threaded rod 8 to rotate, causing the threaded slider 7 on its outer wall to move upward. At the same time, the second air pump 11 starts, and the second air pump 11 inputs gas into the air outlet pipe 9 through the hose 10. Then, the gas in the air outlet pipe 9 is ejected through multiple air nozzles 20. Thus, when the secondary tool magazine door 6 is deflected from bottom to top sequentially, the airflow ejected from the air nozzles will blow out slightly, effectively preventing external contaminants from entering.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
