Description

Technical Field

[0001] The utility model relates to the technical field of aluminum sawing machines, in particular to a head rotation mechanism of an aluminum sawing machine. Background Art

[0002] An aluminum sawing machine is a commonly used electric tool for sawing aluminum alloy profiles, which is widely used in the construction, decoration, and furniture industries. It not only reduces the labor intensity of operators but also improves work efficiency.

[0003] An aluminum sawing machine generally includes a base and a rotatable turntable arranged on the base. A head is connected to the turntable, and the head can rotate longitudinally for cutting. The saw blade of the existing aluminum sawing machine is arranged on the turntable and generally can only rotate longitudinally in one plane. For example, a 45-degree aluminum sawing machine disclosed in the Chinese utility model patent CN209303814U includes a bottom plate. The upper surface of the front part of the bottom plate is fixedly connected with an inclined table. An arc-shaped groove is arranged in the middle of the inclined table. A support column is fixedly connected to the bottom plate. The upper end of the support column is fixedly connected with a motor fixing frame through a rotating shaft. A motor and a handle assembly are fixedly connected to the motor fixing frame. The upper part of the handle assembly is fixedly connected with a handle. The left end of the motor is fixedly connected with a saw blade.

[0004] This kind of aluminum sawing machine has defects. The saw blade is fixedly connected to the motor, and the saw blade is driven to cut the aluminum material by longitudinally rotating the motor fixing frame. Since the saw blade is fixed and cannot move horizontally in the horizontal direction, the cutting angle is fixed, and the working efficiency of the aluminum sawing machine is low. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a head rotation mechanism of an aluminum sawing machine that is convenient to use and has high accuracy.

[0006] The purpose of the utility model is realized through the following technical solutions:

[0007] A head rotation mechanism of an aluminum sawing machine includes a machine base and a head assembly. The machine base is connected to the head assembly. A first housing is provided at the front end of the machine base. The head assembly includes a second housing. The first housing and the second housing are rotatably connected. The first housing is provided with a limiting portion extending into its interior. A resisting member extending into its interior and abutting against the limiting portion for stop limiting is provided on the side wall of the second housing. When the second housing rotates to the right by a certain angle and then rotates the second housing to the left to make it in the vertical direction, the limiting portion and the resisting member stop limiting so that the second housing cannot rotate to the left any more. Pull the limiting portion backward to make the second housing rotate to the left by a certain angle. When the second housing rotates to the right to make it in the vertical direction, the limiting portion resets. The limiting portion and the resisting member stop limiting so that the second housing cannot rotate to the left any more.

[0008] Further, an annular opening facing forward is provided inside the first housing, and an annular opening facing backward is provided inside the second housing.

[0009] Further, the limiting portion is horizontally arranged and horizontally penetrates into the first housing. Part of the limiting portion is exposed outside the first housing, and it can automatically reset after being pulled backward.

[0010] Further, the limiting portion is arranged at a position near the right side of the upper end of the first housing.

[0011] Further, a vertical partition and a horizontal partition are arranged inside the second housing along its diameter direction, and the vertical partition and the horizontal partition are perpendicular to each other.

[0012] Further, the vertical partition includes a first vertical partition and a second vertical partition respectively located on the upper and lower sides inside the second housing, and the horizontal partition includes a first horizontal partition and a second horizontal partition respectively located on the left and right sides inside the second housing.

[0013] Further, an extrusion portion is provided on the inner side wall of the second housing between the first vertical partition and the second horizontal partition. The extrusion portion includes a first connection portion and a second connection portion respectively fixed to the inner side wall of the second housing on the upper and lower sides, and an extrusion plate connected to the first connection portion and the second connection portion respectively.

[0014] Further, the abutting member penetrates into the second housing from the right side wall, passes through the first connection portion and is fixedly connected thereto.

[0015] Further, one end of the limiting portion penetrating into the first housing is located between the first vertical partition and the first connection portion, and the part of the limiting portion exposed outside the first housing is in stop limit with the abutting member.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] In the present utility model, the first housing and the second housing can be rotatably connected. When the machine head assembly is vertical, the abutting member and the limiting portion are in stop limit. When it is necessary to rotate the machine head, the limiting portion is pulled backward, and the machine head can be rotated left or right, greatly increasing the cutting angle of the aluminum sawing machine and expanding the application range.

[0018] And when it is necessary to reposition the machine head after use, when it is rotated left or right to be vertical, the limiting portion resets, and the limiting portion and the abutting member are in stop limit to prevent the machine head from rotating again, playing the role of automatic limiting, and the machine head assembly is repositioned, which is convenient to use.

[0024] The present utility model will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0025] As Figures 1 to 5 shown, a head rotation mechanism of a sawing aluminum machine provided in this embodiment includes a machine base 1 and a head assembly 2. The machine base 1 is connected to the head assembly 2. A first housing 11 is provided at the front end of the machine base 1. The head assembly 2 includes a second housing 21. The first housing 11 and the second housing 21 are rotatably connected. A limiting portion 12 extending into its interior is provided in the first housing 11. A top member 22 extending into its interior and engaging with the limiting portion 12 for stop and limit is provided on the side wall of the second housing 21. When the second housing 21 rotates to the right by a certain angle and rotates the second housing 21 to the left until it is in the vertical direction, the limiting portion 12 and the top member 22 stop and limit so that the second housing 21 cannot rotate to the left anymore; when the limiting portion 12 is pulled backward to rotate the second housing 21 to the left by a certain angle and rotates the second housing 21 to the right until it is in the vertical direction, the limiting portion 12 is reset. The limiting portion 12 and the top member 22 stop and limit so that the second housing 21 cannot rotate to the left anymore. The head assembly 2 can rotate left or right according to needs, greatly increasing the cutting angle, expanding the applicable range, and enhancing the practicability.

[0026] In this embodiment, an annular opening facing forward is provided inside the first housing 11, and an annular opening facing backward is provided inside the second housing 21. The front opening end of the first housing 11 and the rear opening end of the second housing 21 are closed and connected to each other.

[0027] In this embodiment, the limiting portion 12 is horizontally arranged and penetrates into the first housing 11 horizontally. Part of the limiting portion 12 is exposed outside the first housing 11, and the limiting portion 12 can automatically reset after being pulled backward.

[0028] In this embodiment, the limiting portion 12 is arranged at the upper end of the first housing 11 near the right side.

[0029] In this embodiment, a vertical partition 23 and a horizontal partition 24 are provided inside the second housing 21 along its diameter direction, and the vertical partition 23 and the horizontal partition 24 are perpendicular to each other.

[0030] In this embodiment, the vertical partition 23 includes a first vertical partition 231 and a second vertical partition 232 respectively located on the upper and lower sides inside the second housing 21, and the horizontal partition 24 includes a first horizontal partition 241 and a second horizontal partition 242 respectively located on the left and right sides inside the second housing 21.

[0031] In this embodiment, an extrusion part 25 is provided on the inner side wall of the second housing 21 between the first vertical partition 231 and the second horizontal partition 242. The extrusion part 25 includes a first connection part 251 and a second connection part 252 respectively located on the upper and lower sides and fixedly connected to the inner side wall of the second housing 21, and an extrusion plate 253 connected to the first connection part 251 and the second connection part 252 respectively. When the machine head assembly 2 rotates leftward, the extrusion plate 253 compresses the limiting part 12 to make it in a compressed state. When the machine head assembly 2 rotates leftward, no further operation is required, which is convenient and labor-saving.

[0032] In this embodiment, the abutting part 22 penetrates from the right side wall of the second housing 21, passes through the first connection part 251 and is fixedly connected thereto. When the machine head assembly 2 rotates, the abutting part 22 rotates following the second housing 21.

[0033] In this embodiment, when the machine head is in the vertical direction, one end of the limiting part 12 penetrating into the first housing 11 is located between the first vertical partition 231 and the first connection part 251, and the part of the limiting part 12 exposed from the first housing 11 is in stop limit with the abutting part 22.

[0034] After the aluminum saw rotates the machine head to the right during operation, when the machine head assembly 2 needs to be repositioned, rotate the machine head assembly 2 to the left to the vertical direction. The limiting part 12 and the abutting part 22 are in stop limit and the machine head assembly 2 cannot rotate leftward anymore; when the aluminum saw rotates the machine head to the left during operation, pull the limiting part 12 backward so that the limiting part 12 is no longer in stop limit with the abutting part 22. At this time, rotate the machine head assembly 2 to the left, and the extrusion plate 253 will continuously compress the limiting part 12. The aluminum material can be cut at an angle according to the working requirements. When the machine head assembly 2 rotates to the right, the extrusion plate 253 still compresses the limiting part 12 until the machine head assembly 2 rotates to the vertical direction, at which time the extrusion plate 253 no longer compresses the limiting part 12, and the limiting part 12 automatically resets, and the machine head assembly 2 can be repositioned.

[0035] The above are only the preferred embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the utility model description still fall within the scope covered by the patent of the present invention.
