TECHNICAL FIELD

[0001] The present disclosure relates to the field of plate cutting technologies, in particular to, a cutting guide device. BACKGROUND

[0002] End walls of common crane trunk girder mechanisms are rotatably connected with respective pulleys for guiding steel cables. The pulleys are each rotatably connected to a trunk girder through a rotating shaft, and a through hole is pre-drilled on the trunk girder through a boring machine for the rotating shaft to pass through.

[0003] In an actual mounting process of the rotating shaft, it is difficult to directly plug and mount the rotating shaft into the through hole. Usually, an operator needs to use a plasma cutting gun to cut the trunk girder to form a guide slot communicates with the through hole, puts the rotating shaft into the through hole from the guide slot in a sliding manner, and positions the rotating shaft on the trunk girder through a U-shaped limiting block. The rotating shaft is positioned in the through hole through the U-shaped limiting block to achieve the mounting of the rotating shaft.

[0004] Since a trunk girder usually has a large volume, it is difficult to cut it using existing machines. Usually, an operator holds a machine head of a plasma cutting gun and cuts a to-be-cut plate body of the trunk girder to form a guide slot. It is difficult to control a cutting trajectory of the machine head in a manual cutting process, so that the cutting trajectory is easily skewed, which affects a cutting effect. SUMMARY

[0005] In order to relieve the problem of the influence of a cutting effect caused by skewing of a cutting trajectory on a to-be-cut plate, the present disclosure provides a cutting guide device.

[0006] A cutting guide device provided by the present disclosure adopts the following technical solutions.

[0007] A cutting guide device, including a frame arranged on a to-be-cut plate, where the frame is fixedly connected with clamping jaws used for clamping the to-be-cut plate; the frame is provided with guide pillars; the guide pillars are slidably sleeved with respective sliding sleeves; each of the sliding sleeves is rotatably arranged on a corresponding one of the guide pillars; the sliding sleeve is provided with a limiting assembly which is used to fix with the guide pillar; the 1 sliding sleeves are rotatably connected with respective guide seats; a sliding rail is slidably provided on one of the guide seats; a sliding table used for mounting a cutting gun is slidably provided on the sliding rail; and the sliding rail is provided with a fixing assembly used for being fixed with the to-be-cut plate.

[0008] By the adoption of the above technical solution, during cutting the to-be-cut plate, an operator mounts the frame on the to-be-cut plate through the clamping jaws; the operator adjusts the position of the sliding rail, such that a lengthwise direction of the sliding rail is parallel to a cutting trajectory of the cutting gun. Then, the position of the sliding sleeve on the guide pillar is limited by the limiting assembly; and the position of the sliding rail related to the to-be-cut plate is fixed through the fixing assembly. Finally, the operator mounts the cutting gun on the guide seat. At this time, the operator actuates the cutting gun to move in the lengthwise direction of the sliding rail by moving the sliding seat. During cutting the to-be-cut plate, under a guide action of the sliding table and the sliding rail, the cutting gun can only slide in the lengthwise direction of the sliding rail, which reduces cases that a cutting trajectory is bent and skewed when the operator uses the cutting gun. So, the cutting effect of the cutting gun on the to-be-cut plate is improved.

[0009] Optionally, the limiting assembly includes a notch formed in the sliding sleeve; a pressing plate is arranged in the notch; the sliding sleeve is fixedly connected with a support; the support is in threaded connection with a first screw rod; an end portion of the first screw rod is rotatably connected with the pressing plate; and the pressing plate is configured to press against the guide pillar.

[0010] By the adoption of the above technical solution, after completing the adjustment for the position of the sliding rail, the operator screws the first screw rod to actuate the pressing plate to move towards the guide pillar, so that the pressing plate presses the guide pillar to restrain the sliding sleeve from sliding or rotating on the guide pillar.

[0011] Optionally, the fixing assembly includes a base fixedly connected to the sliding rail; the base is fixedly connected with supporting rods used for being plugged into a through hole of the to-be-cut plate; each of the supporting rods is provided with a limiting plate used for abutted against the to-be-cut plate; a push plate is arranged between the base and the to-be-cut plate; the base is in threaded connection with a second screw rod; the second screw rod is rotatably connected with the push plate; and the push plate and the limiting plate are cooperated to clamp the to-be-cut plate.

[0012] By the adoption of the above technical solution, the operator moves the sliding rail, so that the supporting rods are plugged into the through hole, and the limiting plates are abutted 2 against one side of the to-be-cut plate facing away from the sliding rail. Finally, the operator screws the second screw rod to make the push plate and the limiting plates cooperate to clamp the to-be-cut plate, so that the position of the sliding rail is fixed.

[0013] Optionally, the supporting rods include two supporting rods; the two supporting rods are symmetric about the sliding rail; the base is provided with a positioning rod, the positioning rod is able to move in a lengthwise direction of the sliding rail; a first connecting rod and a second connecting rod are hinged between the positioning rod and the base; the first connecting rod is parallel to the second connecting rod; a distance between hinge axes at two ends of the first connecting rod is equal to a distance between hinge axes at two ends of the second connecting rod; a third screw rod is rotatably connected to the base; the third screw rod is in threaded connection with an adjustment nut; the adjustment nut is hinged with one end of a control rod; and an other end of the control rod is hinged to the positioning rod.

[0014] By the adoption of the above technical solution, the operator moves the sliding rail, so that the supporting rods are plugged into the through hole, and the limiting plates are abutted with the side of the to-be-cut plate facing away from the sliding rail. The operator screws the third screw rod to actuate the adjustment nut to move, so that the control rod turns and actuates the positioning rod to press against an inner wall of the through hole, so fixing a position of the sliding rail is achieved, and the sliding rail passes through a central axis of the through hole which facilitates the operator to adjust the position of the sliding rail.

[0015] Optionally, the two supporting rods and the positioning rod are each rotatably connected with rotating sleeves, and the rotating sleeves are used for abutting against an inner wall of the through hole.

[0016] By the adoption of the above technical solution, due to providing the rotating sleeves, the supporting rods and the positioning rod can still control the sliding rail to turn around the through hole while pressing against the inner wall of the through hole, so as to adjust a cutting direction of the cutting gun.

[0017] Optionally, the base is fixedly connected with a guide rail; the guide rail is perpendicular to the sliding rail; the two supporting rods are slidably arranged on the guide rail; a sliding seat is slidably provided on the base and is able to slide in a lengthwise direction of the sliding rail; each of two sides, which are corresponding to the two supporting rods, of the sliding seat is hinged with one end of a push rod; an other end of the push rod is hinged to a corresponding one of the two supporting rods; and the sliding seat is in threaded connection with a limiting bolt, and the limiting bolt is configured to press against the base.

[0018] By the adoption of the above technical solution, the operator adjusts the position of the sliding seat on the base to actuate the two push rods to turn, so as to adjust a distance between the two supporting rods. The operator screws the limiting bolt, so that the limiting bolt is plugged into a corresponding position of a limiting slot to fix the distance between the two supporting rods, so as to adapt to more through holes of different specifications and complete position adjustment for the two supporting rods.

[0020] By the adoption of the above technical solution, the belt presses against the I-shaped wheel under a pulling action of the two tension springs, and the rotation of the I-shaped wheel is restrained by a friction force between the belt and the I-shaped wheel. The I-shaped wheel is coaxially fixedly connected with the gear, so that resistance to the movement of the sliding rail on the guide seat is increased, so as to control a speed of the cutting gun moved by the operator to cut the to-be-cut plate.

[0021] Optionally, the sliding table is fixedly connected with flange plates; each of mounting seats is arranged on a corresponding one of the flange plates; each of sliding chutes is formed in a corresponding one of the mounting seats; each of sliding rods used for being plugged into a corresponding one of the sliding chutes is arranged on the cutting gun; and the mounting seats are in threaded connection with respective locking bolts, and the locking bolts are used for pressing against the sliding rods.

[0022] By the adoption of the above technical solution, when the cutting gun is mounted on the sliding table, the operator aligns the sliding rods on the cutting gun with the sliding chutes, and then plugs the sliding rods into the sliding chutes.

[0023] Optionally, the flange plates include two flange plates; the two flange plates are oppositely arranged with respect to the sliding table; each of the two flange plates is slidably provided with a corresponding one of adjustment plates; a sliding direction of each of the adjustment plates is perpendicular to a lengthwise direction of the sliding rail; each of the mounting seats is fixedly connected to the corresponding one of the adjustment plates; a fourth 4 screw rod is rotatably connected to the sliding table; the fourth screw rod is in threaded connection with an adjustment sleeve; each of two sides, which are corresponding to the two adjustment plates, of the adjustment sleeve is hinged with one end of an adjustment rod; and an other end of the adjustment rod is hinged with the corresponding one of the adjustment plates.

[0024] By the adoption of the above technical solution, the operator screws the fourth screw rod to actuate the adjustment sleeve to move, so that the two adjustment rods are actuated to turn, so as to control each of the adjustment plates to slide in the corresponding one of the flange plates, which facilitates the operator to adjust a distance between the cutting gun and the sliding rail to adapt to through holes of different specifications.

[0025] In conclusion, some embodiments provide at least one of the following beneficial technical effects.

[0026] 1. The sliding rail is mounted on the to-be-cut plate. The sliding table is slidably arranged on the sliding rail, and the cutting gun is fixedly connected to the sliding table, so that the cutting gun is able to cut the to-be-cut plate, and the sliding rail guides a moving trajectory of the cutting gun, which reduces the cases that the cutting trajectory is bent and skewed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The present disclosure is further described in detail below in combination with FIGs. 1-7.

[0037] An embodiment of the present disclosure discloses a cutting guide device. As shown in FIG. 1 and FIG 2, the cutting guide device includes a rodlike frame 2. Each of two ends of the frame 2 is fixedly connected with a supporting rod 21. Each of the two supporting rods 21 is provided with two clamping jaws 22 used for clamping a to-be-cut plate 1. The clamping jaw 22 includes flip plate 23. The flip plate 23 is hinged to the supporting rod 21 through a rotating shaft 24. The rotating shaft 24 is located at middle position of the flip plate 23. An elongated slot 25 is formed in one end of each of the flip plates 23, and a lengthwise direction of the elongated slot 25 is perpendicular to an axis of the rotating shaft 24. The double-head stud 26 is rotatably connected with the supporting rods 21, and the double-head stud 26 is in threaded connection with two sleeves 27. Two threaded ends of the double-head stud 26 corresponding to the two sleeves 27 have opposite spiral directions. Each of the sleeves 27 corresponds to one of the flip plates 23, and each of the sleeves 27 is arranged in a corresponding one of the elongated slots 25 in a penetrating manner. Limiting shaft 28 used for restraining the sleeve 27 from being separated from the elongated slot 25 is arranged at two ends of the sleeve 27. Waist-shaped holes 29 in which limiting shaft 28 is able to slide are formed in two slot walls of the elongated slot 25 of the flip plate 23. Lengthwise direction of the waist-shaped hole 29 is parallel to lengthwise direction of the elongated slot 25. The end of the flip plate 23 away from the double-head stud 26 is hinged with a clamping block 231 which is used for pressing against the to-be-cut plate 1. An operator screws the double-head stud 26 to actuate the two sleeves 27 thereon to be away from 6 each other, thus actuating the two clamping blocks 231 to be close to each other and to clamp the to-be-cut plate 1.

[0038] Each of two sides of the frame 2 is fixedly connected with a cylindrical guide pillar 3 which is perpendicular to the double-head stud 26, and axial directions of the two guide pillars 3 are both parallel to a lengthwise direction of the support 33. Each of the two guide pillars 3 are slidably sleeved with a sliding sleeve 31, and the sliding sleeve 31 is rotatable around the guide pillar 3. The sliding sleeve 31 is provided with limiting assembly 32 used for restraining the sliding sleeve 31 from moving on the guide pillar 3. The sliding sleeve 32 includes a support 33 fixedly connected to the sliding sleeve 31, and a pressing plate 34 is provided on the support 33. The pressing plate 34 is able to move parallel to a radial direction of the guide pillar 3. A notch for the pressing plate 34 to pass through is formed in the sliding sleeve 31. The support 33 is further in threaded connection with a first screw rod 35, and an axial direction of the first screw rod 35 is parallel to the radial direction of the guide pillar 3. An end portion of the first screw rod 35 is rotatably connected to the pressing plate 34. The operator can rotate the first screw rod 35 to actuate the pressing plate 34 to move towards the guide pillar 3, so that the pressing plate 34 presses against the guide pillar 3 to restrain the sliding sleeve 31 from moving on the guide pillar 3.

[0039] As shown in FIG. 1 and FIG. 3, a guide seat 4 is rotatably connected to the sliding sleeve 31, and a rotating axis of the guide seat 4 is perpendicular to an axial direction of the guide pillar 3. A guide slot 41 is formed in the guide seat 4. A sliding rail 42 is arranged on one side of the guide seat 4. The sliding rail 42 is fixedly connected with a guide block 43. The guide block 43 is slidably arranged in the guide slot 41, so that the sliding rail 42 is able to slide on the guide seat 4 in its lengthwise direction.

[0040] As shown in FIG. 1 and FIG. 4, one side, which faces away from the sliding sleeve 31, of the sliding rail 42 facing away from the sliding sleeve 31 is fixedly connected with a rack 44, and a lengthwise direction of the rack 44 is parallel to the lengthwise direction of the sliding rail 42. A gear 45 is rotatably connected to the guide seat 4 and is engaged with the rack 44. One side of the gear 45 is coaxially fixedly connected with an I-shaped wheel 46, and a belt 47 is wound on the I-shaped wheel 46. The guide seat 4 is fixedly connected with a supporting plate 48. Two ends of the belt 47 extend towards the supporting plate 48, and are connected to the supporting plate 48 through tension springs 49. The tension springs 49 are in a stretched state, the belt 47 presses against the I-shaped wheel 46 to increase the resistance to rotation of the gear 45 and then increase the resistance that is overcome by the sliding rail 42 to move on the guide seat 4, so that the random movement of the sliding rail 42 on the guide seat 4 is restrained.

[0041] As shown in FIG. 5 and FIG. 6, one end of the sliding rail 42 extends towards the through hole 11, and a fixing assembly 5 for being fixed with the to-be-cut plate 1 is arranged at the one end of the sliding rail 42 which is close to the through hole 11. The fixing assembly 5 includes a base 51 which is fixedly connected to the one end of the sliding rail 42 which is close to the through hole 11. The base 51 is fixedly connected with a guide rail 52. A lengthwise direction of the guide rail 52 is parallel to the axial direction of the guide pillar 3, and a cross section of the guide rail 52 is square. Two moving seats 53 are arranged on the guide rail 52, able to slide along the lengthwise direction of the guide rail 52 and symmetric to each other about the sliding rail 42. A side of each of the two moving seats 53 facing away from the sliding rail 42 is perpendicularly fixedly connected with supporting rods 54. A limiting plate 69 used for pressing against one side of the to-be-cut plate 1 facing away from the base 51 is arranged at an end, which is away from the sliding seat 57, of each of the two supporting rods 54. A sliding seat 57 is provided on the base 51 and is able to slide along a direction parallel to the sliding rail 42. Each of both sides of the sliding seat 57 corresponding to the two moving seats 53 is hinged with one end of a push rod 56. An other end of the push rod 56 is hinged to a corresponding one of the moving seats 53. The operator moves the sliding seat 57 to actuate the two supporting rods 54 to be close to or away from each other. The sliding seat 57 is penetrated with a limiting bolt 55, and the limiting bolt 55 is in threaded connection with the sliding seat 57 and presses against the base 51. A lower end of the base 51 is in threaded connection with a second screw rod 67, and an end portion of the second screw rod 67 is rotatably connected with a push plate 68 which is used for pressing against the to-be-cut plate 1. The push plate 68 cooperates with the limiting plate 69 to clamp the to-be-cut plate 1.

[0042] One side of the base 51 facing the through hole 11 is fixedly connected with a base rod 58. A lengthwise direction of the base rod 58 is parallel to lengthwise directions of the supporting rods 54. The base rod 58 is provided with a positioning rod 6 which is movable in the lengthwise direction of the sliding rail 42, and an axial direction of the positioning rod 6 is parallel to axial directions of the two supporting rods 54. A first connecting rod 61 and a second connecting rod 62 which are parallel to each other are arranged between the positioning rod 6 and the base 51. One end of the first connecting rod 61 and one end of the second connecting rod 62 are both hinged with the positioning rod 6, and the other end of the first connecting rod 61 and the other end of the second connecting rod 62 are both hinged with the base rod 58. A distance between hinge axes of the two ends of the first connecting rod 61 is equal to a distance between hinge axes of the two ends of the second connecting rod 62, so that the positioning rod 6 is kept in parallel to the two supporting rods 54 during a turning process. The base 51 is 8 penetrated with a third screw rod 63, and the third screw rod 63 is rotatably connected with the base 51. The third screw rod 63 is parallel to the positioning rod 6. One end of the third screw rod 63 facing the through hole 11 is in threaded connection with an adjustment nut 64. The adjustment nut 64 is hinged with one end of a control rod 65, and the other end of the control rod 65 away from the adjustment nut 64 is hinged with the positioning rod 6. The operator screws the third screw rod 63 to actuate the control rod 65 to turn, which actuates the positioning rod 6 to be close to or away from the third screw rod 63. When the positioning rod 6 cooperates with the two supporting rods 54 to press against the inner wall of the through hole 11, the sliding rail 42 passes through a central axis of the through hole 11. The positioning rod 6 and the two supporting rods 54 are each rotatably connected with a rotating sleeve 66 to facilitate the sliding rail 42 to turn around the axis of the through hole 11.

[0043] As shown in FIG. 1 and FIG. 7, a sliding table 7 is slidably arranged on one side of the sliding rail 42 facing away from the to-be-cut plate 1, and each of two sides of the sliding table 7 facing away from the sliding rail 42 is fixedly connected with a flange plate 71. The two flange plates 71 are symmetric about the sliding table 7 in the lengthwise direction of the guide pillar 3. An adjustment plate 72 is slidably arranged on the flange plate 71, and a sliding direction of the adjustment plate 72 is perpendicular to a lengthwise direction of the sliding rail 42. A fourth screw rod 73 between the two flange plates 71 is rotatably connected to the sliding table 7, and an axial direction of the fourth screw rod 73 is parallel to the axial direction of the positioning rod 6. The fourth screw rod 73 is in threaded connection with an adjustment sleeve 74, and each of two sides, which is corresponding to the two adjustment plates 72, of the adjustment sleeve 74 is hinged with one end of adjustment rod 75. The other end of each of the two adjustment rods 75 away from the sliding seat 57 is hinged to the corresponding one of the adjustment plates 72. The operator screws the fourth screw rod 73 to actuate the adjustment sleeve 74 to move. Under the linkage action of the adjustment rods 75, the two adjustment plates 72 are actuated to be close to or away from each other.

[0044] Ends of the two adjustment plates 72 away from each other are fixedly connected with mounting seats 8, and sliding chutes 81 with T-shaped cross sections are formed in the mounting seats 8. A cutting gun 83 is fixedly connected with sliding rods 82 which fit in the sliding chutes 81. The mounting seats 8 are penetrated with locking bolts 84, and the locking bolts 84 are in threaded connection with the mounting seats 8. The operator screws down the locking bolts 84, so that the locking bolts 84 presses against the sliding rods 82, so as to fix the positions of the cutting guns in relation to the sliding table 7. Under the guide action of the sliding table 7 and the sliding rail 42, a cutting trajectory of the cutting gun is parallel to the sliding rail 42, so that skewing of the cutting trajectory of the cutting gun is reduced.

[0045] An implementation principle of the embodiment of the present disclosure is as follows. Before cutting the to-be-cut plate 1, the operator first mounts the frame 2 on the to-be-cut plate 1. The operator then moves the sliding rail 42, so that the supporting rods 54 and the positioning rod 6 on the sliding rail 42 are each located in the through hole 11. The operator screws the third screw rod 63 to actuate the positioning rod 6 to move away from the third screw rod 63 until the positioning rod 6 and the two supporting rods 54 press against the inner wall of the through hole 11. At this time, the limiting plates 69 on the two supporting rods 54 press against the side of the to-be-cut plate 1 facing away from the base 51. The operator can turn the sliding rail 42 to make the sliding rail 42 to rotate around the through hole 11, in which the sliding sleeve 31 slides on the guide pillar 3, and the sliding rail 42 slides on the guide seat 4 until the sliding rail 42 moves to be parallel to a preset cutting trajectory. The operator then screws the first screw rod 35 to actuate the pressing plate 34 to press against the guide pillar 3, so that the sliding sleeve 31 is fixedly connected to the guide pillar 3. The operator then screws the second screw rod 67 to actuate the push plate 68 to move towards the to-be-cut plate 1, so that the limiting plates 69 cooperate with the push plate 68 to clamp the to-be-cut plate 1, which achieves final fixing of the sliding rail 42 on the to-be-cut plate 1.

[0046] To cut the to-be-cut plate 1, the operator slidably plugs the sliding rod 82 on the cutting gun in the sliding chute 81, adjusts a distance between a gun head of the cutting gun and the to-be-cut gun 1, and then screws down the locking bolts 84 to fixedly connect the cutting gun to the sliding table 7. In the cutting process, the operator pushes the cutting gun, so that the cutting gun and the sliding table 7 move in the lengthwise direction of the sliding rail 42 and cut the to-be-cut plate 1. The cutting trajectory of the cutting gun is parallel to the sliding rail 42, which improves the uniformity of the cutting trajectory of the cutting gun and the cutting effect.

[0047] The preferred embodiments of the present disclosure are described above, and are not intended to limit the protection scope of the present disclosure. Therefore, any equivalent changes made according to the structure, shape and principle of the present disclosure shall all fall within the protection scope of the present disclosure.
