DETAILED DESCRIPTION

[0036] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0037] like Figures 1 to 8 As shown, the present invention provides a horizontal cradle structure five-axis composite machining table, comprising a machine body 1;

[0038] A processing mechanism 2, which is slidably connected to the back of the top end of the body 1;

[0039] A cradle clamping mechanism 3, which is slidably connected to the front of the top of the body 1;

[0040] A collecting frame 4 is movably mounted on the inner wall of the middle part of the machine body 1;

[0041] The air intake assembly 5 is fixedly mounted at the middle of the bottom end of the back side of the machine body 1;

[0042] The ventilation mechanism 6 includes a ventilation pipe 601, which is movably installed between the bottom of the collection frame 4 and the top of the front end of the suction component 5. A ventilation valve flap 602 is fixedly installed on the inner wall of the top of the ventilation pipe 601. The bottom of the collection frame 4 is fixedly installed on the filter top pipe 603 inside the ventilation valve flap 602. Limiting sliders 604 are fixedly installed on both sides of the ventilation valve flap 602. The left and right ends of the limiting slider 604 are respectively provided with a locking component 11 and a first pneumatic component 7. A linkage component 8 located in the middle of the back side of the cradle clamping mechanism 3 is fixedly installed on the top of the body 1. The linkage component 8 drives the first pneumatic component 7 to drive the ventilation mechanism 6 to move upward as a whole, so that the front end part of the suction component 5 can be released from the seal, and the locking component 11 can be operated to fix it.

[0043] The second piston rod 802 moves backward to push the gas in the inner cavity of the linkage air pipe 801 through the first connecting pipe 804 and the first air channel 703 to enter the pneumatic cavity 701, and can push the first piston rod 702 to drive the limiting slider 604 and the ventilation pipe 601 to move upward as a whole, so that the bottom end of the filter top pipe 603 can press the ventilation valve flap 602 to open, so that the filter top pipe 603 is connected with the ventilation pipe 601 and the suction pipe 503, and at the same time, the ventilation pipe 601 and the suction pipe 503 are connected with the inner cavity of the collection frame 4, which is convenient for subsequent ash suction.

[0044] like Figure 2 As shown, the air suction component 5 includes a suction fan 501, an exhaust pipe 502 and an air suction pipe 503;

[0045] The suction fan 501 is fixedly installed in the middle of the bottom end of the back side of the machine body 1, the exhaust pipe 502 is fixedly connected to the middle of the back side of the suction fan 501, the suction pipe 503 is fixedly connected to the middle of the front side of the suction fan 501 and the inner wall of the top front end is slidably connected to the ventilation pipe 601.

[0046] By adopting the above scheme, a suction fan 501 is provided. When the suction fan 501 is running, the suction pipe 503 can suck the gas on the inner wall and the upper part of the collection frame 4, and then discharge it from the exhaust pipe 502, thereby achieving the purpose of dust collection.

[0047] like Figure 3 As shown, the first pneumatic assembly 7 includes a pneumatic chamber 701, a first piston rod 702 and a first air passage 703;

[0048] The pneumatic chamber 701 is opened on the inner wall of the body 1 and on the top of the first air channel 703 at the right end. The first piston rod 702 is movably installed on the inner wall of the pneumatic chamber 701 and the bottom end is fixedly connected to the first air channel 703. The first air channel 703 is opened on the inner wall of the body 1 and is fixedly connected to the bottom of the right end of the pneumatic chamber 701.

[0049] By adopting the above scheme, a first piston rod 702 is provided. When the air pressure in the pneumatic chamber 701 becomes larger, the first piston rod 702 can pull the limiting slider 604 and the ventilation pipe 601 to move upward as a whole, so that the ventilation valve flap 602 is propped up and flipped open by the filter top pipe 603, so that the air intake pipe 503 and the ventilation pipe 601 are unsealed, and then the air intake pipe 503 can smoothly extract the gas in the inner cavity of the collection frame 4 and the gas above it through the ventilation pipe 601 and the filter top pipe 603.

[0050] like Figure 4 As shown, the linkage assembly 8 includes a linkage air pipe 801, a second piston rod 802, a return spring 803 and a first connecting pipe 804;

[0051] The linkage air pipe 801 is fixedly installed on the top of the body 1 and the back of the cradle clamping mechanism 3, the second piston rod 802 is movably installed in the inner cavity of the linkage air pipe 801, the return spring 803 is fixedly installed on the back of the second piston rod 802, and the first connecting pipe 804 is fixedly connected to the middle part of the back of the linkage air pipe 801 and the bottom end is fixedly connected to the other end of the first air channel 703.

[0052] By adopting the above scheme, a second piston rod 802 is provided. When the second piston rod 802 is pushed by the cradle clamping mechanism 3 to slide backward in the inner cavity of the linkage air pipe 801, the gas in the inner cavity of the linkage air pipe 801 can be pushed to enter the inner cavity of the pneumatic cavity 701 through the first connecting pipe 804 and the first air channel 703, so that the inner cavity of the pneumatic cavity 701 becomes larger and smoothly drives the first piston rod 702 to pull the limiting slider 604 and the ventilation pipe 601 to rise.

[0053] like Figure 4 As shown, the rear end of the return spring 803 is fixedly connected to the inner wall of the linkage air pipe 801 .

[0054] By adopting the above scheme, a return spring 803 is provided. When the second piston rod 802 moves backward as a whole, the return spring 803 will be compressed. When the cradle clamping mechanism 3 moves forward, the elastic force of the return spring 803 can drive the second piston rod 802 to return forward. At the same time, the gas in the pneumatic cavity 701 is drawn back into the linkage air pipe 801 through the first air channel 703 and the first connecting pipe 804, so that the first piston rod 702 pushes the limit slider 604 and the air pipe 601 to return downward.

[0055] like Figure 5 As shown, the inner wall of the body 1 is provided with a shielding assembly 9 located at the top of the collecting frame 4, and the shielding assembly 9 includes a shielding plate 901 and a movable sleeve rod 902;

[0056] The shielding plate 901 is movably mounted on the inner wall of the body 1 and the bottom of the cradle clamping mechanism 3, and the movable sleeve rod 902 is fixedly sleeved on the outer side of the inner wall of the shielding plate 901 and the right end extends to the inner wall of the body 1 and is movably sleeved;

[0057] There are two shielding plates 901 , and the two shielding plates 901 have the same size.

[0058] With the above solution, a shielding plate 901 is provided. When the two shielding plates 901 are turned upward by 90 degrees to completely shield the top of the collecting frame 4, it is possible to effectively prevent dust and impurities from entering the outside when not in operation.

[0059] like Figure 7 and Figure 8 As shown, the inner wall of the body 1 is provided with a second pneumatic assembly 10 located inside the rear end of the movable sleeve rod 902, and the second pneumatic assembly 10 includes a pneumatic tube 101, an arc-shaped push rod 102, a second air passage 103 and a second connecting tube 104;

[0060] The pneumatic tube 101 is fixedly installed on the inner wall of the body 1 and on the upper inner side of the rear end of the movable sleeve rod 902. The arc push rod 102 is movably installed in the inner cavity of the pneumatic tube 101 and the outer end is fixedly connected to the movable sleeve rod 902. The second air channel 103 is opened on the inner wall of the body 1 and the top of the outer end is fixedly connected to the bottom of the pneumatic tube 101. The second connecting tube 104 is fixedly connected to the front end of the outer side of the linkage air pipe 801.

[0061] By adopting the above scheme, an arc-shaped push rod 102 is provided. When the air pressure in the pneumatic tube 101 changes, the arc-shaped push rod 102 can move in the inner cavity of the pneumatic tube 101 to drive the movable sleeve rod 902 and the baffle plate 901 to flip back and forth, thereby realizing the sealing and opening operation of the top of the collection frame 4.

[0062] like Figure 7 As shown, the other end of the second air passage 103 is fixedly connected to the bottom of the outer end of the second connecting pipe 104 .

[0063] By adopting the above scheme, a second connecting tube 104 is provided. When the second piston rod 802 moves, the gas in the linkage air pipe 801 can be introduced into the inner cavity of the pneumatic tube 101 through the second connecting tube 104 and the second air channel 103 or the gas in the inner cavity can be sucked away, so that the air pressure in the inner cavity of the pneumatic tube 101 changes smoothly and drives the arc push rod 102 to move.

[0064] like Figure 3 As shown, the locking assembly 11 includes a pneumatic cylinder 1101 and a locking block 1102;

[0065] The pneumatic cylinder 1101 is fixedly installed inside the machine body 1 and on the left side of the left-end limiting slider 604 , and the locking block 1102 is fixedly installed on the right side of the pneumatic cylinder 1101 and on the inner cavity of the limiting slider 604 .

[0066] By adopting the above scheme, a locking block 1102 is provided. When the limit slider 604 moves upward, the inclined surface at the bottom end of the locking block 1102 will be squeezed, thereby pushing the gas in the inner cavity of the pneumatic cylinder 1101 to compress so that the limit slider 604 can be smoothly fixed upward. When the fixation is released, the pneumatic cylinder 1101 can be directly controlled to move and drive the locking block 1102 to move to the left.

[0067] The working principle and use process of the present invention:

[0068] First, the operator can clamp the workpiece and place it on the top of the cradle clamping mechanism 3, then start the cradle clamping mechanism 3 backward until it is directly under the processing mechanism 2, and then start the processing mechanism 2 to process the workpiece. After the cradle clamping mechanism 3 is moved backward and fixed, the second piston rod 802 will move backward so that the gap at the front end of the inner cavity of the linkage air pipe 801 becomes larger and negative pressure is generated, thereby the gas in the pneumatic tube 101 is extracted through the second connecting pipe 104 and the second air channel 103, and then the arc push rod 102 will drive the two movable sleeve rods 902 and the baffle plate 901 to deflect 90 degrees and open downward, and the processed debris will fall into the collection frame 4 for collection;

[0069] Afterwards, as the second piston rod 802 moves backward, the gas in the rear end inner cavity of the linkage air pipe 801 can be synchronously pushed to enter the inner cavity of the pneumatic cavity 701 through the first connecting pipe 804 and the first air passage 703, thereby pushing the first piston rod 702 to pull the limit slider 604 and the air pipe 601 to move upward as a whole, and the inner cavity of the left end limit slider 604 will be opposite to the pneumatic cylinder 1101, and then the locking block 1102 is started to push the pneumatic cylinder 1101 to the left to move the limit slider 604 and the ventilation pipe 601 are fixed as a whole, at which time the bottom end of the filter top pipe 603 will abut against the ventilation valve flap 602 to make it open, and then the sealing cover of the ventilation pipe 601 and the suction pipe 503 can be released. Then, when the processing is completed, the suction fan 501 can be started to make the suction pipe 503 generate suction, so that the dust and debris attached to the cradle clamping mechanism 3 at the top of the collection frame 4 can be fully vacuumed through the ventilation pipe 601 and the filter top pipe 603.

[0070] The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
