Description

Technical Field

[0001] The present invention belongs to the technical field of concrete product processing, and specifically relates to a concrete product cutting machine for construction. Background Technique

[0002] With the rapid development of the construction industry, the demand for building materials is increasing day by day, and concrete products stand out with their unique advantages. In building construction, blocks, as a common building material among concrete products, are cut into the required shapes by a concrete product cutting machine.

[0003] In the prior art, the hardened blocks are placed on the working table of the cutting machine, and the saw blade is driven by a lift to move up and down quickly, and the quickly moving saw blade moves horizontally to cut the blocks.

[0004] There are still some deficiencies in the prior art during actual use. Due to the diversity of building designs and the complexity of construction requirements, different requirements are put forward for the shapes of blocks. When triangular or rectangular blocks need to be cut, the existing block cutting equipment often needs to adjust the placement position of the blocks to achieve this. This operation not only requires operators to have a high skill level to ensure cutting accuracy, but also the process is relatively cumbersome, and the angles and positions of the blocks need to be adjusted repeatedly to reach the required shape. Such complex operations not only reduce construction efficiency, increase labor costs, but also may cause material waste due to cutting errors, making the existing block cutting equipment unable to cope with diverse shape requirements.

[0011] Preferably, a fixing component is arranged on the fixed bracket. The fixing component is composed of a clamping component and an abutting component; The clamping component includes a trigger plate. Two wedge-shaped blocks are slidably arranged in one displacement block. The wedge-shaped blocks are on the movement track of the clamping rod. After the clamping rod is inserted into the clamping groove, the rack I is made stationary by the clamping of the clamping rod and the two wedge-shaped blocks; The abutting component includes a first rotating sleeve. A fastening sleeve is rotatably provided at one end of the first rotating sleeve. A guiding block is fixedly connected to the outer surface of the fastening sleeve. A threaded groove is formed in the inner wall of the third movement groove. The guiding block is in threaded connection with the threaded groove. By rotating the first rotating sleeve to drive the first one-way rotating rod to rotate, the fastening sleeve abuts against the second outer gear collar, so that the second outer gear collar remains relatively fixed.

[0012] Preferably, the clamping component further includes two contraction grooves which are respectively formed in the inner walls on both sides of the clamping groove. A wedge block slides in one contraction groove. One end of each wedge block is fixedly connected with a moving plate. The moving plate slides in the contraction groove.

[0017] The beneficial effects of the present invention are as follows: 1. When the rotating block rotates in the present invention, it drives the torsion spring to elastically contract and drives the outer gear collar one to rotate, causing the rack one to move, thereby stretching the return spring one until the clamping rod abuts against the wedge-shaped block. At this time, the saw blade rotates 90 degrees to make the saw blade vertically placed, and the rack one stops moving, thereby changing the cutting direction of the saw blade, enabling the saw blade to cut the building block from the vertical direction. By rotating the rotating sleeve one counterclockwise, under the action of belt drive, the inner wall of the abutting groove one abuts against the rotating plate, and one side of the rotating plate abuts against one side inner wall of the abutting groove two, thereby relatively fixing the rotating sleeve two and the one-way rotating rod two under the action of the rotating plate. Furthermore, the one-way rotating rod two rotates and drives the outer gear collar two to rotate through the guiding gear two, thereby adjusting the direction of the saw blade to make the saw blade rotate with the center of the outer gear collar two as the horizontal center. Through the adjustment in the above two directions, the cutting direction and method of the saw blade are diversified, and the building block can be cut into the required shape more simply, preventing the problem that the angle and position of the building block need to be repeatedly adjusted to reach the required shape, improving the construction efficiency, and reducing the labor cost.

[0018] 2. In the present invention, the clamping rod first abuts against the wedge-shaped block to keep the saw blade fixed after rotation, further ensuring the stability of the saw blade after adjusting the cutting direction. By rotating the rotating sleeve one clockwise, the one-way rotating rod two is stationary, while the one-way rotating rod one drives the fastening sleeve to rotate. Under the action of the guiding block and the thread groove, while the fastening sleeve rotates, it moves towards the direction close to the outer gear collar two, thereby relatively fixing the outer gear collar two, preventing the outer gear collar two from loosening, making the saw blade in the expected position, further improving the stability of the saw blade during cutting after adjusting the direction, and preventing the problem of deviation during cutting.

Detailed implementation manners

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners. Embodiment

[0023] As Figures 1 to 14As shown in the figure, a cutting machine for concrete products used in construction according to an embodiment of the present invention includes a fixed bracket 11. An outer gear sleeve 51 is rotatably connected inside the fixed bracket 11. A rectangular bracket 24 is fixedly connected to the inner ring surface of the outer gear sleeve 51. A moving device 25 is arranged on one side of the rectangular bracket 24. The moving device 25 includes two displacement blocks 26. A cutting device 21 is arranged between the two displacement blocks 26. The cutting device 21 includes a saw blade 23. One end of the saw blade 23 is fixedly connected to a connecting rod 27. The connecting rod 27 rotates inside a reciprocating rod 22; A steering component is arranged on the fixed bracket 11. The steering component is composed of a rotating part and a horizontal rotating part; A rotating block 31 is rotatably connected to each displacement block 26. The saw blade 23 penetrates through the two rotating blocks 31. A rotating disc is fixedly arranged at one end of the saw blade 23. The rotating part is arranged inside one displacement block 26. The rotating part includes an outer gear sleeve 35. The outer gear sleeve 35 is fixed to the bottom of the rotating block 31. A rack 36 is slidably arranged inside the displacement block 26. One end of the rack 36 is fixedly connected to a clamping rod 38. A clamping groove 39 is opened at one end of the displacement block 26. When the rotating block 31 rotates, the rack 36 is driven to move through the outer gear sleeve 35. Until the rotating block 31 rotates 90 degrees, at this time the cutting direction of the saw blade 23 changes, and the clamping rod 38 is inserted into the clamping groove 39 to keep the rack 36 stationary, so that the rotating block 31 is stationary; The horizontal rotating part is arranged inside the fixed bracket 11. The horizontal rotating part includes a movement groove 52. A rotating sleeve 512 is rotatably arranged inside the movement groove 52. One end of the rotating sleeve 512 is rotatably provided with a one-way rotating rod 513. One end of the one-way rotating rod 513 is fixedly connected to a guiding gear 515. The guiding gear 515 meshes with the outer gear sleeve 51. By rotating the rotating sleeve 512, the one-way rotating rod 513 drives the guiding gear 515 to rotate synchronously, so that the outer gear sleeve 51 drives the cutting device 21 and the moving device 25 to rotate synchronously, thereby adjusting the direction of the saw blade 23.

[0024] Specifically, a workbench 1 is arranged at one end of the fixed bracket 11. The building block is placed on the workbench 1; When it is necessary to cut the building block, by starting the driving device on the cutting device 21, the reciprocating rod 22 drives the saw blade 23 to move up and down reciprocally. Subsequently, the driving device on the moving device 25 is started to make the two displacement blocks 26 move synchronously, thereby driving the cutting device 21 to move and making the saw blade 23 cut the building block; In the actual use process of the prior art, there are still some deficiencies. Due to the diversity of building designs and the complexity of construction requirements, different requirements are put forward for the shapes of building blocks. When it is necessary to cut out triangular or rectangular building blocks, the existing building block cutting equipment often needs to adjust the placement position of the building blocks to achieve this. This operation not only requires operators to have a relatively high skill level to ensure cutting accuracy, but also the process is relatively cumbersome, and the angles and positions of the building blocks need to be adjusted repeatedly to obtain the required shape. Such complex operations not only reduce the construction efficiency, increase the labor cost, but also may cause material waste due to cutting errors, making the existing building block cutting equipment appear inadequate when dealing with diverse shape requirements.

[0025] Therefore, the present invention solves this problem by setting corresponding structures. When it is necessary to cut out triangular or rectangular building blocks, the rotating disk on the saw blade 23 can be rotated to make the rotating block 31 rotate. Then, one rotating block 31 rotates normally, and the torsion spring 33 on the other rotating block 31 elastically contracts and drives the movement groove 34 to move until the saw blade 23 rotates 90 degrees. At this time, the clamping rod 38 is clamped to make the rack 36 stationary, thereby completing the change of the cutting direction of the saw blade 23. Subsequently, the rotation of the rotating sleeve 512 drives the one-way rotating rod 513 to drive the guiding gear 515 to rotate synchronously, so that the outer gear sleeve ring 51 drives the cutting device 21 and the moving device 25 to rotate synchronously, thereby adjusting the direction of the saw blade 23. Then, the cutting device 21 and the moving device 25 are operated, and the saw blade 23 cuts out the required shape. Embodiment

[0026] As Figures 2 to 14 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: As Figures 7 to 10 、 Figure 13 and Figure 14 shown, a fixing component is arranged on the fixing bracket 11 in this embodiment. The fixing component is composed of a clamping component and an abutting component; The clamping component includes a trigger plate 47. Two wedge-shaped blocks 311 are slidably arranged in a displacement block 26. The wedge-shaped blocks 311 are on the movement track of the clamping rod 38. When the clamping rod 38 is inserted into the clamping groove 39, the rack 36 is made stationary through the clamping of the clamping rod 38 and the two wedge-shaped blocks 311; The abutting component includes a rotating sleeve 53. One end of the rotating sleeve 53 is rotatably provided with a fastening sleeve 510. A guiding block 511 is fixedly connected to the outer surface of the fastening sleeve 510. A threaded groove is opened on the inner wall of the movement groove 52. The guiding block 511 is threadedly connected to the threaded groove. The rotation of the rotating sleeve 53 drives the one-way rotating rod 54 to rotate, so that the fastening sleeve 510 abuts against the outer gear sleeve ring 51, thereby keeping the outer gear sleeve ring 51 relatively fixed.

[0027] Specifically, the shape of the clamping rod 38 matches the shape of the contraction groove 310. During the process of the clamping rod 38 moving to the clamping groove 39, the clamping rod 38 first abuts against the wedge-shaped block 311, causing the wedge-shaped block 311 to contract until the clamping rod 38 no longer abuts against the wedge-shaped block 311. At this time, the wedge-shaped block 311 resets and clamps the clamping rod 38, so that the first rack 36 can only remain relatively stationary; After adjusting the direction of the saw blade 23, by rotating the first rotating sleeve 53, the fastening sleeve 510 abuts against the guide block 511, relatively fixing the second external gear sleeve ring 51, thereby preventing the second external gear sleeve ring 51 from loosening and keeping the saw blade 23 in the expected position.

[0028] As Figures 3 to 8 shown, the rotating component of this embodiment further includes a reset cavity 32. The reset cavity 32 is opened at the top of the displacement block 26. A torsion spring 33 is fixedly connected between the outer surface of the rotating block 31 and the inner wall of the reset cavity 32. A first movement groove 34 is opened at the bottom of the rotating block 31. The first external gear sleeve ring 35 rotates in the first movement groove 34. The first rack 36 slides in the first movement groove 34. The first external gear sleeve ring 35 meshes with the first rack 36. One end of the first rack 36 is fixedly connected with a first reset spring 37 between the inner wall of one end of the first movement groove 34. The clamping groove 39 is opened at the other end of the first rack 36; The clamping component further includes two contraction grooves 310. The two contraction grooves 310 are respectively opened on the inner walls on both sides of the clamping groove 39. One wedge-shaped block 311 slides in one contraction groove 310. One end of each wedge-shaped block 311 is fixedly connected with a moving plate 312. The moving plate 312 slides in the contraction groove 310. One end of the moving plate 312 is fixedly connected with a second reset spring 313 between the contraction groove 310.

[0029] A second movement groove 41 is opened in one displacement block 26. A first guide plate 42 is slidably connected in the second movement groove 41. One end of the first guide plate 42 is fixedly connected with a second rack rod 43. A second guide plate 44 is slidably arranged on one side of the first guide plate 42. One end of the second guide plate 44 is fixedly connected with a third rack 45. One side of the third rack 45 is rotatably connected with a first guide gear 46. One end of the trigger plate 47 is fixedly connected with the bottom end of the second rack rod 43.

[0030] The second movement groove 41 is communicated with the contraction groove 310. One end of the first guide plate 42 is fixed to one moving plate 312. One end of the second guide plate 44 is fixed to the other moving plate 312. The second rack rod 43 and the third rack 45 are arranged in a staggered and symmetric manner. Both the second rack rod 43 and the third rack 45 mesh with the first guide gear 46.

[0031] Specifically, initially, the saw blade 23 is placed horizontally and linearly; When the rotating block 31 rotates, the torsion spring 33 is elastically contracted and the outer gear ring 1 35 is rotated, so that the rack 1 36 moves, thereby stretching the reset spring 1 37 until the clamping rod 38 abuts against the wedge block 311. At this time, the saw blade 23 rotates 90 degrees, so that the saw blade 23 is placed vertically, and the rack 1 36 is stationary, thereby changing the cutting direction of the saw blade 23; When the clamping rod 38 abuts against the wedge block 311, the clamping rod 38 abuts against the wedge block 311 first, causing the wedge block 311 to contract. The movement of the wedge block 311 causes the second return spring 313 to contract elastically, driving the second rack rod 43 and the third rack 45 to move downward until the clamping rod 38 no longer abuts against the wedge block 311. Under the effect of the elastic release of the second return spring 313, the wedge block 311 is reset, causing the wedge block 311 to clamp against the clamping rod 38, thereby making the first rack 36 stationary. When the saw blade 23 needs to be reset, the trigger plate 47 is pushed to move, and the wedge block 311 is moved synchronously through the movement of the trigger plate 47, so that the reset spring 2 313 is elastically contracted, and the rack 3 45 drives the other wedge block 311 to move through the transmission of the guide gear 1 46, so that the two wedge blocks 311 move toward each other. At this time, the wedge block 311 is no longer engaged with the clamping rod 38. Under the action of the elastic contraction of the torsion spring 33 and the reset spring 1 37, the rack 1 36 is reset, thereby resetting the saw blade 23.

[0032] like Figures 9 to 14 As shown, the horizontal rotating component of this embodiment also includes a one-way rotating component, which includes an abutting groove 1 55, which is provided in the rotating sleeve 2 512, and an abutting groove 2 56 is provided at one end of the one-way rotating rod 2 513, and a fixed shaft 57 is fixedly connected in the abutting groove 2 56, and a rotating plate 58 is rotatably connected to the surface of the fixed shaft 57, and a tension spring 59 is fixedly connected between the rotating plate 58 and the abutting groove 2 56; The abutment component also includes a one-way rotating rod 54, which is rotatably arranged in a rotating sleeve 53, and a one-way rotating component is arranged between the rotating sleeve 53 and the one-way rotating rod 54. An abutment groove 55 in the one-way rotating component is arranged in the rotating sleeve 53, and an abutment groove 2 56 is arranged at one end of the one-way rotating rod 54. The fastening sleeve 510 slides on the surface of the one-way rotating rod 54. The two one-way rotating components are symmetrically arranged, and a belt 514 is connected to the rotating sleeve 53 and the rotating sleeve 2 512 for transmission.

[0033] Specifically, when it is necessary to adjust the direction of the saw blade 23, rotate the first rotating sleeve 53 counterclockwise. At this time, the inner wall of the first abutting groove 55 abuts against the rotating plate 58, causing the rotating plate 58 to rotate around the fixed shaft 57 as the axis and elastically compressing the tension spring 59 until the rotating plate 58 is pressed into the second abutting groove 56. At this time, the first one-way rotating rod 54 remains stationary until the rotating plate 58 enters the next groove of the first abutting groove 55. Through the elastic release of the tension spring 59, the rotating plate 58 is reset, and the above operation is repeated; The rotation of the first rotating sleeve 53 drives the rotation of the second rotating sleeve 512 through the transmission of the belt 514. Since the two one-way rotating components are symmetrically arranged, through the above operation, the inner wall of the first abutting groove 55 abuts against the rotating plate 58, and one side of the rotating plate 58 abuts against one side inner wall of the second abutting groove 56, so that the second rotating sleeve 512 and the second one-way rotating rod 513 are relatively fixed under the action of the rotating plate 58, and then the second one-way rotating rod 513 rotates, and drives the second outer gear sleeve ring 51 to rotate through the second guiding gear 515, thereby adjusting the direction of the saw blade 23; After adjusting the direction of the saw blade 23, rotate the first rotating sleeve 53 clockwise. Through the above operation, the second one-way rotating rod 513 remains stationary, while the first one-way rotating rod 54 drives the fastening sleeve 510 to rotate. Under the action of the guiding block 511 and the threaded groove, while the fastening sleeve 510 rotates, it moves towards the direction close to the second outer gear sleeve ring 51, and then relatively fixes the second outer gear sleeve ring 51, thereby preventing the second outer gear sleeve ring 51 from loosening and keeping the saw blade 23 in the expected position.

[0034] When the rotating block 31 rotates in the present invention, it drives the torsion spring 33 to elastically contract and drives the first outer gear sleeve ring 35 to rotate, causing the first rack 36 to move, so that the first reset spring 37 is stretched until the clamping rod 38 abuts against the wedge-shaped block 311. At this time, the saw blade 23 rotates 90 degrees, making the saw blade 23 vertically placed, and the first rack 36 remains stationary, thereby changing the cutting direction of the saw blade 23, enabling the saw blade 23 to cut the building block from the vertical direction. By rotating the first rotating sleeve 53 counterclockwise, under the transmission action of the belt 514, the inner wall of the first abutting groove 55 abuts against the rotating plate 58, and one side of the rotating plate 58 abuts against one side inner wall of the second abutting groove 56, so that the second rotating sleeve 512 and the second one-way rotating rod 513 are relatively fixed under the action of the rotating plate 58, and then the second one-way rotating rod 513 rotates, and drives the second outer gear sleeve ring 51 to rotate through the second guiding gear 515, thereby adjusting the direction of the saw blade 23, making the saw blade 23 rotate horizontally with the center of the second outer gear sleeve ring 51 as the center. Through the adjustment of the above two directions, the cutting direction and method of the saw blade 23 are diversified, and the building block can be cut into the required shape more simply, preventing the problem that the angle and position of the building block need to be repeatedly adjusted to reach the required shape, improving the construction efficiency and reducing the labor cost.

[0035] In the present invention, the clamping rod 38 first abuts against the wedge block 311 to keep the saw blade 23 fixed after rotation, further ensuring the stability of the saw blade 23 after adjusting the cutting direction. By rotating the first rotating sleeve 53 clockwise, the second one-way rotating rod 513 remains stationary, while the first one-way rotating rod 54 drives the fastening sleeve 510 to rotate. Under the action of the guiding block 511 and the thread groove, while the fastening sleeve 510 rotates, it moves towards the direction close to the second external gear sleeve ring 51, thereby relatively fixing the second external gear sleeve ring 51, preventing the second external gear sleeve ring 51 from loosening, keeping the saw blade 23 in the expected position, further improving the stability of the saw blade 23 during cutting after adjusting the direction, and preventing the problem of deviation during cutting.

[0036] Working principle: When it is necessary to cut triangular or rectangular building blocks, the rotating disk on the saw blade 23 can be rotated to make the rotating block 31 rotate. When the rotating block 31 rotates, it drives the torsion spring 33 to elastically contract and drives the first external gear sleeve ring 35 to rotate, making the first rack 36 move, thereby stretching the first return spring 37 until the clamping rod 38 abuts against the wedge block 311. At this time, the saw blade 23 rotates by ninety degrees to make the saw blade 23 vertically placed, and the first rack 36 remains stationary, thus changing the cutting direction of the saw blade 23. During the process of the clamping rod 38 abutting against the wedge block 311, the clamping rod 38 first abuts against the wedge block 311, causing the wedge block 311 to contract. Through the movement of the wedge block 311, the second return spring 313 elastically contracts and drives the second rack rod 43 and the third rack 45 to move downward until the clamping rod 38 no longer abuts against the wedge block 311. Under the action of the elastic release of the second return spring 313, at this time, the wedge block 311 resets, making the wedge block 311 engage with the clamping rod 38, and further making the first rack 36 stationary. When it is necessary to reset the saw blade 23, the trigger plate 47 is pushed to move. Through the movement of the trigger plate 47, the wedge block 311 moves synchronously, making the second return spring 313 elastically contract. Through the transmission of the first guiding gear 46, the third rack 45 drives another wedge block 311 to move, making the two wedge blocks 311 move towards each other. At this time, the wedge block 311 no longer engages with the clamping rod 38. Under the action of the elastic contraction of the torsion spring 33 and the first return spring 37, the first rack 36 resets, thereby resetting the saw blade 23.

[0037] When it is necessary to adjust the direction of the saw blade 23, the first rotating sleeve 53 is rotated counterclockwise. At this time, the inner wall of the first abutting groove 55 abuts against the rotating plate 58, making the rotating plate 58 rotate around the fixed shaft 57 as the axis and elastically compressing the tension spring 59 until the rotating plate 58 is pressed into the second abutting groove 56. At this time, the first one-way rotating rod 54 remains stationary until the rotating plate 58 enters the next groove of the first abutting groove 55. Through the elastic release of the tension spring 59, the rotating plate 58 resets, and the above operation is repeated. The rotation of the first rotating sleeve 53 drives the rotation of the second rotating sleeve 512 through the transmission of the belt 514. Since the two one-way rotating components are symmetrically arranged, through the above operations, the inner wall of the first abutting groove 55 abuts against the rotating plate 58, and one side of the rotating plate 58 abuts against one side inner wall of the second abutting groove 56, so that the second rotating sleeve 512 and the second one-way rotating rod 513 are relatively fixed under the action of the rotating plate 58. Furthermore, the second one-way rotating rod 513 rotates and drives the second outer gear sleeve ring 51 to rotate through the second guiding gear 515, thereby adjusting the direction of the saw blade 23; After adjusting the direction of the saw blade 23, rotate the first rotating sleeve 53 clockwise. Through the above operations, the second one-way rotating rod 513 remains stationary, while the first one-way rotating rod 54 drives the fastening sleeve 510 to rotate. Under the action of the guiding block 511 and the threaded groove, while the fastening sleeve 510 rotates, it moves towards the direction close to the second outer gear sleeve ring 51, and then relatively fixes the second outer gear sleeve ring 51, thereby preventing the second outer gear sleeve ring 51 from loosening, making the saw blade 23 in the expected position. Subsequently, operate the cutting device 21 and the moving device 25, and then the saw blade 23 cuts out the required shape.
