Description

TECHNICAL FIELD

[0002] Integrated house, also known as fabricated house, is a house formed by transporting and assembling prefabricated wallboard, floor slab and other components in a factory to a construction site. At present, temporary offices, dormitories in construction sites, houses for large field exploration and field operation construction in transportation, water conservancy, petroleum and natural gas industries, temporary houses for city office, civilian resettlement and exhibition, leisure villas and holiday houses in tourist areas, and houses for earthquake relief are widely used integrated houses.

[0003] At present, wallboard, floor slab and other components of integrated house are formed by using a mold, that is, materials are laid into the mold and then demolded after the materials are dried. This method is more suitable for batch production of integrated house components with relatively simple shapes, because the mold quantity is relatively small and the mold utilization rate is high. However, for leisure villas, holiday houses and other integrated houses, it is difficult to meet the user's demand with the same simple shape. However, the design of integrated houses with various shapes will inevitably require more components with different shapes and sizes, and the unique shape of the integrated house will inevitably not be mass-produced. Therefore, if the components are still formed by using a mold, it will result in excessive mold quantity, high investment and low mold utilization rate.

[0004] Based on the above reasons, some integrated house components can be produced by first producing large-area integrated house components and then cutting them into smaller components.

DETAILED DESCRIPTION

[0033] The application is further illustrated below in combination with the drawings and specific embodiments.

[0034] As shown in Figure 1 and Figure 2 , the integrated house component cutting machine comprises component support fixing structure 1, front and back displacement device 2, crossbeam 3, tool rest 4, tool rest driving device 6, indexing device 7 and blade assembly 5; the component support fixing structure 1 can support and fix the integrated house component 9; the front and back displacement device 2 is two in number, and the two front and back displacement devices 2 are respectively arranged on the left and right sides of the component support fixing structure 1; the crossbeam 3 is located above the component support fixing structure 1, and the two ends of the crossbeam 3 are installed on the front and back displacement devices 2; the tool rest 4 comprises moving tool rest 41 and rotating tool rest 42, the moving tool rest 41 is connected with the crossbeam 3, the tool rest driving device 6 can drive the moving tool rest 41 to move along the crossbeam 3, the rotating tool rest 42 is connected with the moving tool rest 41, and the indexing device 7 can drive the rotating tool rest 42 to rotate by 90°; the blade assembly 5 is installed on the rotating tool rest 42, and the blade assembly 5 comprises rotary cutting blade 54, and the lower part of the cutting blade 54 is exposed from the tool rest 4.

[0035] The specific steps of cutting the integrated house component by using the application are as follows:

[0036] A, as shown in Figure 2 , the front and back displacement device 2 moves the crossbeam 3 and the tool rest 4, the tool rest driving device 6 and the blade assembly 5 carried by the crossbeam 3 to the rear of the component support fixing structure 1, so that the component support fixing structure 1 is vacated.

[0037] B. Place the large integrated house component 9 on the component support fixing structure 1 and fix it.

[0038] C. The knife holder driving device 6 drives the knife holder 4 to move to the left of the beam 3, the front and back shifting device 2 moves to adjust the position of the cutting blade 54, and the cutting position is found. Then the knife holder driving device 6 drives the knife holder 4 to move to the right, and drives the cutting blade 54 to move to the right, and at the same time the cutting blade 54 rotates, so that the left and right direction cuts on the integrated house component 9 can be cut out.

[0039] D. The indexing device 7 drives the rotating knife holder 42 to rotate 90°, and the cutting blade 54 also rotates 90°. Then the knife holder driving device 6 drives the knife holder 4 to move left and right to find the cutting position, and the front and back shifting device 2 drives the cutting blade 54 to move forward and backward, and at the same time the cutting blade 54 rotates, so that the front and back direction cuts can be cut out. In this way, the large integrated house component 9 can be cut into small integrated house components of various sizes.

[0040] The component support fixing structure 1 is used to support and lift the integrated house component 9, and fix the integrated house component 9 to avoid moving under the action of the cutting blade 54. The specific structure of the component support fixing structure 1 is preferably as shown in Figures 3 to 5 : The component support fixing structure 1 includes a support seat 11 and a fixer 12; the support seat 11 is composed of a plurality of support columns 111 arranged at intervals, and the support columns 111 have vertical threaded holes 1111 and horizontal threaded holes 1112; the fixer 12 includes a fixing strip 121, an L-shaped fixing plate 122, an end plate 123, a top tightening bolt 124 and a pressing bolt 125; the fixing strip 121 has a fixing strip long hole 1211 arranged along the length direction thereof, and the L-shaped fixing plate 122 and the end plate 123 are connected to the two ends of the fixing strip 121 respectively; the fastening piece passes through the fixing strip long hole 1211 and is connected with the vertical threaded hole 1111, and the fastening piece presses the fixing strip 121; the top tightening bolt 124 passes through the end plate 123 and is connected with the horizontal threaded hole 1112; and the pressing bolt 125 is connected with the L-shaped fixing plate 122.

[0041] Each support column 111 is preferably arranged in a rectangular array, and the top surface should be flush to form a plane for placing the integrated house component 9. There is a distance between each support column 111 for the cutting blade 54 to pass through.

[0042] After the integrated house component 9 is placed, several supporting columns 111 are selected around the integrated house component 9 for installing the fixing device 12. The fixing strip 121 is placed on the supporting column 111, and the fastener is passed through the long hole 1211 of the fixing strip and connected with the vertical threaded hole 1111, and the fastener lightly presses the fixing strip 121. Then the jacking bolt 124 is passed through the end plate 123 and connected with the horizontal threaded hole 1112; the jacking bolt 124 is tightened, so that the L-shaped fixing plate 122 tightly abuts against the integrated house component 9. Then the fixing strip 121 is tightly pressed by tightening the fastener. Then the jacking bolt 125 is connected with the L-shaped fixing plate 122 and tightened, and the jacking bolt 125 tightly abuts against the integrated house component 9 downward. After the fixing device 12 is installed, the integrated house component 9 is fixed.

[0043] The front and rear displacement device 2 can adopt an existing linear slide.

[0044] The cross beam 3 is used for installing the tool holder 4 and guiding the tool holder 4 to move left and right, and the cross beam 3 should have sufficient bending resistance. As shown in Figure 1 , Figure 2 , Figure 6 and Figure 8 , the cross beam 3 of the present application adopts a frame structure, which comprises two horizontal guide rails 31 and an upper cross beam, the two horizontal guide rails 31 are arranged at intervals, the upper cross beam is located above the horizontal guide rails 31, and a plurality of connecting rods connect the two horizontal guide rails 31 and the horizontal guide rails 31 and the upper cross beam, so that the cross beam 3 forms a frame with a triangular cross section, thereby ensuring its bending resistance. A sliding block 33 is sleeved on each of the two horizontal guide rails 31, the sliding block 33 has a sliding block hole 331, a first fixing cylinder 34 is connected with the sliding block 33, a fixed head 35 is located in the sliding block hole 331, and when the first fixing cylinder 34 is elongated, the fixed head 35 abuts against the horizontal guide rail 31; a moving tool holder 41 is connected with the sliding block 33.

[0045] The moving tool holder 41 is connected with the sliding block 33, so it can move left and right with the sliding block 33. When the cutting blade 54 moves left and right to cut a left-right direction slit, the first fixing cylinder 34 should be shortened, the fixed head 35 does not abut against the horizontal guide rail 31, and the sliding block 33 can move along the horizontal guide rail 31. After the rotating tool holder 42 is indexed, when the cutting blade 54 moves forward and backward to cut a forward-backward direction slit, the sliding block 33 cannot move along the horizontal guide rail 31, at this time the first fixing cylinder 34 is elongated, the fixed head 35 abuts against the horizontal guide rail 31, so that the sliding block 33 has a friction force with the horizontal guide rail 31 to limit the movement of the sliding block 33.

[0046] The specific structure of the first fixing cylinder 34 is shown in Figure 9 , which has a return spring in the rod cavity. The rod cavity is not supplied with oil, so that the return spring supports the piston, the piston rod is retracted, and the fixed head 35 does not abut against the horizontal guide rail 31. The rod cavity is supplied with oil, so that the piston rod is elongated, and the fixed head 35 abuts against the horizontal guide rail 31. The first fixing cylinder 34 relies on the pressure of the hydraulic oil to make the fixed head 35 abut against the horizontal guide rail 31.

[0047] The tool holder driving device 6 is used to drive the tool holder 4 to move along the cross beam 3. The specific mode is preferably as shown in Figure 7 and Figure 8 The cross beam 3 comprises a rack 32; the tool holder driving device 6 comprises a tool holder driving machine 61, a gear shaft 62, a gear 64 and a gear shaft seat 63, the tool holder driving machine 61 and the gear shaft seat 63 are installed on the moving tool holder 41, the gear shaft 62 is installed on the gear shaft seat 63, the tool holder driving machine 61 is connected with the gear shaft 62, and the gear 64 is connected with the gear shaft 62 and engaged with the rack 32.

[0048] The tool holder driving machine 61 drives the gear shaft 62 and the gear 64 to rotate, and since the gear 64 is engaged with the rack 32, the tool holder 4 moves along the cross beam 3. Bearings can be provided between the gear shaft seat 63 and the gear shaft 62 to facilitate smooth rotation of the gear shaft 62.

[0049] As shown in Figures 6 to 10 The specific structure of the tool holder 4 is preferably as follows: the moving tool holder 41 has a positioning large hole 411 and three arc-shaped long holes 412 arranged around the positioning large hole 411; the rotating tool holder 42 comprises a rotating disc 421, a second fixed cylinder 422 and a pressing disc 423, the rotating disc 421 has a positioning protrusion 4211, the rotating disc 421 is placed on the moving tool holder 41, the positioning protrusion 4211 is inserted into the positioning large hole 411 and cooperates with the positioning large hole 411; the number of the second fixed cylinders 422 is three, the second fixed cylinders 422 are arranged one by one corresponding to the arc-shaped long holes 412, the second fixed cylinders 422 are connected with the rotating disc 421, the piston rods of the second fixed cylinders 422 pass through the rotating disc 421 and the arc-shaped long holes 412, the piston rods are in close contact with one end of the arc-shaped long holes 412, the pressing disc 423 is located below the moving tool holder 41 and is connected with the piston rods, the second fixed cylinders 422 are shortened to make the pressing disc 423 press the moving tool holder 41; after the rotating disc 421 rotates 90°, the piston rods are in close contact with the other end of the arc-shaped long holes 412.

[0050] The positioning protrusion 4211 inserted into the positioning large hole 411 and cooperating with the positioning large hole 411 can limit the translation of the rotating tool holder 42. The arc-shaped long holes 412 limit the rotation angle of the rotating tool holder 42. The second fixed cylinders 422 are shortened to make the pressing disc 423 press the moving tool holder 41, which limits the rotation and up-down movement of the rotating tool holder 42. In this way, the rotating tool holder 42 is completely fixed, and the rotating tool holder 42 should be completely fixed except during indexing.

[0051] When the rotating tool holder 42 is indexed, the second fixed cylinder 422 is extended, the pressing disc 423 does not press the movable tool holder 41, and the rotating tool holder 42 can be indexed to adjust the direction of the cutting blade 54. The second fixed cylinder 422 should be extended slightly to avoid obvious up and down movement of the rotating tool holder 42. Preferably, when the second fixed cylinder 422 is extended, the distance between the pressing disc 423 and the movable tool holder 41 is 2-3 mm. In this way, although the pressing disc 423 does not press the movable tool holder 41, it still limits the obvious up and down movement of the rotating tool holder 42, and can avoid obvious up and down movement of the rotating tool holder 42 during indexing.

[0052] The specific structure of the second fixed cylinder 422 is preferably as shown in Figure 11 The rod cavity has a plurality of stacked butterfly springs 4221, the butterfly springs 4221 are sleeved on the piston rod, the elastic force of the butterfly springs 4221 makes the piston rod retract, thereby driving the pressing disc 423 to press the movable tool holder 41, and the stacked butterfly springs 4221 have great elastic force after compression, meeting the requirements of the present application. When the rotating tool holder 42 is indexed, the rod cavity of the second fixed cylinder 422 is supplied with oil, the hydraulic pressure drives the piston and the piston rod to move downward, thereby driving the pressing disc 423 to move downward, at this time the pressing disc 423 does not press the movable tool holder 41, and the rotating tool holder 42 can be indexed.

[0053] The specific structure of the indexing device 7 is preferably as shown in Figure 12 The indexing device 7 is arranged in the left-right direction and located at the rear of the component supporting and fixing structure 1, the indexing device 7 includes a fixed beam 71, a friction plate 74, an indexing guide rod 72, and a spring 73, the indexing guide rod 72 passes through the fixed beam 71 and cooperates with the fixed beam 71, the friction plate 74 is connected with the indexing guide rod 72, the spring 73 is located between the friction plate 74 and the fixed beam 71, the spring 73 abuts against the fixed beam 71 and front-tops the friction plate 74; the forward-backward displacement device 2 drives the rotating disc 421 to move rearward to tightly abut against the friction plate 74, the tool holder driving device 6 drives the rotating disc 421 to move leftward and rightward, and the friction plate 74 drives the rotating disc 421 to rotate.

[0054] The indexing device 7 alone cannot realize the indexing of the rotary tool holder 42, and the indexing device 7 cooperates with the front and rear displacement device 2 and the tool holder driving device 6 to realize the indexing of the rotary tool holder 42. The specific implementation process is as follows: A, the front and rear displacement device 2 drives the tool holder 4 to move backward, so that the rotary disc 421 is in close contact with the friction plate 74 and presses the friction plate 74 backward, so that the spring 73 is compressed, and the elastic force of the spring 73 makes the rotary disc 421 and the friction plate 74 have a suitable extrusion force. B, the second fixed cylinder 422 is elongated, and the pressure of the pressure plate 423 on the moving tool holder 41 is released. C, the tool holder driving device 6 starts to drive the tool holder 4 to move left and right, so that the rotary disc 421 rolls on the friction plate 74, and the rotary disc 421 rotates. D, when the piston rod is in close contact with the other end of the arc-shaped long hole 412, the rotary disc 421 just rotates 90° and cannot continue to rotate, the second fixed cylinder 422 is shortened, the pressure plate 423 is pressed to the moving tool holder 41, and the indexing of the rotary tool holder 42 is completed.

[0055] The indexing device 7 cooperates with the front and rear displacement device 2 and the tool holder driving device 6 to realize indexing, without the need for additional power to drive the rotary tool holder 42 to index, the structure is simple, the cost is greatly reduced, and the weight of the tool holder 4 is not increased.

[0056] The specific structure of the blade assembly 5 can be as shown in Figure 13 The blade assembly 5 includes a blade shaft seat 53, a blade shaft 52, and a blade driving machine 51, the blade driving machine 51 and the blade shaft seat 53 are installed on the rotary tool holder 42, the blade shaft 52 is installed on the blade shaft seat 53, and the blade driving machine 51 and the cutting blade 54 are connected with the blade shaft 52.

[0057] The above-mentioned blade assembly 5 is a relatively conventional structure, the blade shaft seat 53 supports the blade shaft 52, bearings can be provided between the blade shaft 52 and the blade shaft seat 53 to ensure smooth rotation of the blade shaft 52. The blade driving machine 51 drives the blade shaft seat 53 to rotate, and the cutting blade 54 installed on the blade shaft seat 53 rotates to realize cutting.

[0058] Although the above-mentioned blade assembly 5 is a structure applied to many blades, the blade shaft 52 is a cantilever beam structure, only the blade shaft seat 53 on one side of the cutting blade 54 supports the blade shaft 52, and the stress state of the blade shaft 52 is not very good. The cutting force required for cutting integrated house components is large, and the cutting blade 54 and the blade shaft 52 are subjected to a large stress, which easily causes the cutting blade 54 and the blade shaft 52 to be slightly deflected, and thus damaged.

[0059] Therefore, the present invention preferably includes a support shaft 55, a support shaft seat 56, and a support shaft seat moving device 57. The support shaft seat moving device 57 includes a support seat guide rod 571, a screw 572, a crank handle 574, and a locking nut 573. The support seat guide rod 571 and the screw 572 are arranged in the same direction as the blade shaft 52 and are both mounted on the rotating tool holder 42. The crank handle 574 is connected to the screw 572, and the locking nut 573 is connected to the screw 572 and abuts against the rotating tool holder 42 to restrict the rotation of the screw 572. The support shaft seat 56 is fitted on the support seat guide rod 571 and threadedly connected to the screw 572. The support shaft 55 is mounted on the support shaft seat 56 and is coaxial with the blade shaft 52. The support shaft 55 is inserted into the blade shaft 52 and cooperates with the blade shaft 52. The support shaft 55 and the blade shaft 52 are keyed together.

[0060] The support shaft seat 56 supports the support shaft 55; the support shaft 55 is inserted into and mates with the blade shaft 52, and the support shaft 55 and the blade shaft 52 are keyed together. Therefore, the support shaft 55 supports the blade shaft 52, and the support shaft 55 and the blade shaft 52 rotate together. The two ends of the blade shaft 52 are supported by the blade shaft seat 53 and the support shaft 55 respectively, so the cutting blade 54 and the blade shaft 52 will not wobble and have strong force resistance.

[0061] The cutting blade 54 cuts the prefabricated housing component 9 and is prone to wear, making it a vulnerable part of this invention. The cutting blade 54 needs to be replaced after wear. While simply using a support shaft 55 to support the blade shaft 52 improves the stability of the blade shaft 52, it hinders the removal of the cutting blade 54. Therefore, this invention provides a support shaft seat moving device 57, which drives the support shaft seat 56 and the support shaft 55 to move. When the support shaft 55 moves away from the blade shaft 52 and has a certain gap between it and the blade shaft 52 (this gap is greater than the thickness of the cutting blade 54), the cutting blade 54 can be removed through this gap, and it can also be inserted through this gap and installed on the blade shaft 52. Figure 13 As shown, loosen the locking nut 573, turn the crank 574, and the screw 572 will rotate, causing the support shaft seat 56 to move along the support seat guide rod 571, so that the support shaft 55 can be inserted into or removed from the blade shaft 52.

[0062] In addition to the above structure, the present invention should also have an electronic control device, like other devices, such as... Figure 1 and 2As shown, an electric control box 8 is arranged on the left of the component supporting and fixing structure 1. A controller is arranged in the electric control box 8 for controlling the operation of each electric component. The present application can adopt the conventional control button control mode, i.e. the operation of the forward and backward shifting device 2, the first fixing cylinder 34, the blade driving machine 51, the second fixing cylinder 422 and the tool holder driving machine 61 are all controlled by pressing the control buttons. Some operations of the present application can also be automatically controlled by the controller (e.g. PLC), such as the automatic movement of the cutting blade 54 during cutting.

[0063] Since the present application has the first fixing cylinder 34 and the second fixing cylinder 422, the present application should be provided with a corresponding hydraulic system for driving the first fixing cylinder 34 and the second fixing cylinder 422. The hydraulic system is relatively simple and is the prior art, and it is only necessary to control the oil supply to the first fixing cylinder 34 and the second fixing cylinder 422.
