Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a cutting device for building materials. Background Art

[0002] Building materials are a general term for various materials used in construction projects. Many long-shaped building materials such as square timber, boards, steel, and rebar have uniform lengths when they are produced as finished products. However, in actual use, they need to be cut according to certain length specifications to meet usage requirements.

[0003] For example, Chinese utility model CN222242916U discloses a building material cutting device, in which the output end of the second motor drives the cutting wheel to rotate, and the rotation of the second screw drives the second slider to move along the axial direction of the second screw, thereby driving the cutting wheel to move and cut building materials of different lengths.

[0004] However, in the prior art, the cutting wheel can only move laterally along the screw. Since the diameter of the cutting wheel is fixed, when cutting building materials with a large thickness or height, it cannot be directly cut off in one cut. The building materials need to be flipped or turned over before cutting, resulting in poor adaptability and ease of use of the cutting device. Summary of the Invention

[0005] The object of the present invention is to provide a cutting device for building materials, which solves the problem of poor adaptability and ease of use of existing cutting devices by allowing the sliding seat to slide along one of the fixed side plates to cut one side of the building material, and when the sliding seat slides to the other fixed side plate and slides along this fixed side plate, cutting the other side of the building material.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] Example 1

[0036] See also Figure 1 and 2 As shown, the present invention is a cutting device for building materials, including a frame 1 and two lifting work platforms 7. The two lifting work platforms 7 are respectively located on both sides of the frame 1. The lifting work platforms 7 are used to support and fix the building materials and adjust the vertical cutting position of the building materials.

[0037] like Figure 3 and 4As shown, the frame 1 is fixedly connected to two fixed side plates 101 arranged side by side. The two fixed side plates 101 are arranged up and down, and one end of the two fixed side plates 101 is connected to a semicircular ring plate 102. The fixed side plates 101 and the semicircular ring plate 102 are fixed to the frame by bolts, so that the two fixed side plates 101 and the semicircular ring plate 102 are combined into Type structure.

[0038] like Figure 3 As shown, a sliding seat 2 is slidably connected between the side surfaces of the semicircular ring plate 102 and the two fixed side plates 101 , and the sliding seat 2 slides from one fixed side plate 101 to the other fixed side plate 101 through the semicircular ring plate 102 .

[0039] Specifically, such as Figure 5 、 6 As shown in Figures 8 and 9, the sliding seat 2 is connected to a drive assembly, which drives the sliding seat 2 to slide. The drive assembly includes a guide rail 103, and the guide rail includes a semicircular segment connected to the semicircular ring plate 102 and a straight segment respectively fixed to the two fixed side plates 101. The sliding seat 2 slides along the fixed side plates 101 via the straight segment and slides from one fixed side plate 101 to the other fixed side plate 101 via the semicircular segment.

[0040] The drive assembly also includes a rack 104 and a drive device 5 connected to the sliding base 2. The rack 104 is located outside the rail 103 and is arranged parallel to the guide rail 103. The sliding base 2 is rotatably connected to a rotating shaft 201. One end of the rotating shaft 201 is fixedly connected to a running wheel 202 that engages with the rack 104, and the other end is in transmission connection with the drive device 5. The power device 5 drives the running wheel 202 to rotate, causing the running wheel 202 to roll along the rack 104, thereby enabling the sliding base 2 to slide along the guide rail 103.

[0041] Among them, the driving device 5 includes a motor and a reducer, the rotating shaft 201 is fixedly connected to the first worm gear 203, the sliding seat 2 is rotatably connected to the first worm 204 engaged with the first worm gear 203 through the bearing bracket, and the first worm 204 is transmission-connected to the driving device 5, thereby utilizing the self-locking property between the worm gear and the worm gear, so that after the driving device 5 stops, the walking wheel 202 will not rotate accidentally, so that the sliding seat 2 can maintain a fixed position.

[0042] like Figure 8 and 10 As shown, the sliding seat 2 is connected to the cutting support 3, the cutting support 3 is connected to the driving motor 4, and the output shaft of the driving motor 4 is connected to the cutting blade 401, so that when the sliding seat 2 slides along one of the fixed side plates 101, one side of the building material is cut, and when the sliding seat 2 slides to the other fixed side plate 101 and slides along this fixed side plate 101, the other side of the building material is cut.

[0043] As shown in Figure 2, the building material is fixed on the lifting workbench 7 and is started by the driving device 5, so that the sliding seat 2 moves horizontally on the upper fixed side plate 101 to cut the upper side of the building material. When the building material is thick and cannot be cut directly, the sliding seat 2 is moved so that it passes through the semicircular ring plate 102 and reaches the lower fixed side plate 101. At this time, the sliding seat 2 is used horizontally along the lower fixed side plate 101 to cut the lower side of the building material, thereby completely cutting the building material through two upper and lower cutting operations.

[0044] Thus, by switching the position of the sliding seat 2 between the two fixed side plates 101, both sides of the building material can be cut separately. By avoiding the need to flip or turn over the building material for cutting, the cutting device can cut building materials of various sizes, greatly improving the overall adaptability and ease of use.

[0045] Example 2

[0046] Based on the first embodiment, Figure 5 、 6 As shown in Figure 9, the rotating shaft of the first worm 204 is fixedly connected to the first driven wheel 205. The sliding base 2 is rotatably connected to the transmission shaft 6 that is transmission-connected to the driving device 5. The transmission shaft 6 is fixedly connected to the first driving wheel 601 that meshes with the first driven wheel 205. The output end of the driving device 5 is transmission-connected to the spline sleeve 501, which is rotationally connected to the sliding base 2. The upper end of the transmission shaft 6 is a spline shaft structure that cooperates with the spline sleeve 501.

[0047] The cutting support 3 and the sliding seat 2 are slidingly connected through a guide rail slider assembly. The sliding direction of the cutting support 3 relative to the sliding seat 2 is the vertical direction. The sliding seat 2 is rotatably connected to the screw rod 301 through the bearing seat. The cutting support 3 is fixedly connected to the nut 302 that cooperates with the screw rod 301. The vertical position of the cutting support 3 is adjusted by rotating the screw rod 301, thereby realizing the adjustment of the cutting depth of the cutting blade 401.

[0048] At the same time, one end of the screw rod 301 is fixedly connected to the second worm gear 206, and the sliding base 2 is rotatably connected to the second worm 207 meshing with the second worm gear 206 through the bearing seat. The rotating shaft of the second worm 207 is fixedly connected to the second driven gear 208, and the transmission shaft 6 is fixedly connected to the second driving gear 602 meshing with the second driven gear 208.

[0049] Furthermore, the sliding seat 2 is slidably connected to a push plate 603 and fixedly connected to a telescopic device 604 connected to the push plate 603; the telescopic device 604 can be an electric push rod. The lower end of the drive shaft 6 is rotatably connected to the push plate 603, and the upper end is engaged with the spline sleeve 501 for transmission. The telescopic device 604 drives the drive shaft 6 axially. At any given time, only the first driving wheel 601 is engaged with the first driven wheel 205 or the second driving wheel 602 is engaged with the second driven wheel 208.

[0050] Specifically, such as Figure 6 As shown, when the position of the cutting support 3 needs to be adjusted, the telescopic device 604 pulls down the push plate 603, driving the transmission shaft 6 to move axially downward. At this time, the first driving wheel 601 is separated from the first driven wheel 205, and the second driving wheel 602 is engaged with the second driven wheel 208, thereby driving the second worm 207 to rotate through the action of the driving device 5, and then driving the screw 301 to rotate through the second worm wheel 206, thereby adjusting the position of the cutting support 3.

[0051] like Figure 7 As shown, when the sliding seat 2 needs to be moved, the push plate 603 is pushed up by the telescopic device 604, driving the transmission shaft 6 to move axially upward. At this time, the first driving wheel 601 is engaged with the first driven wheel 205, and the second driving wheel 602 is separated from the second driven wheel 208. The first worm 204 is driven to rotate by the driving device 5, and then the rotating shaft 201 is driven to rotate by the first worm gear 203, so that the walking wheel 202 rotates, and the position movement of the sliding seat 2 is adjusted, thereby adjusting the axial position of the transmission shaft 6 and switching the power transmission. Therefore, the sliding seat 2 and the cutting support 3 can be driven to move separately by one driving device 5, thereby effectively reducing the number of power components and making the overall structure more compact.
