Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a tool for processing metal profiles. Background Art

[0002] At present, in the process of producing and processing metal parts, it is generally necessary to go through cutting, grinding, polishing and other operations. In these processing processes, in order to ensure the processing quality and stability of metal parts, clamping tools are often needed. For example, for aluminum profiles, which are currently widely used, when turning the inner wall to prepare a smooth inner surface, different clamping devices are usually set in the circumference of the aluminum profile, and clamping force is applied radially to maintain the stability of the aluminum profile; however, it is found in practice that: if the clamping force is relatively small, the aluminum profile is unstable and difficult to process stably; if sufficient clamping force is maintained, there is a high probability that the profile will be deformed to a certain extent, resulting in different turning amounts on the inner wall, resulting in poor turning processing. In addition, existing clamping mechanisms often require their own power source, or are clamped by some clamping mechanisms that require manual active operation, which requires high physical strength from the operator and has high labor intensity.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0036] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] See also Figures 1 to 6As shown, this example provides a tool for metal profile processing, and the metal profile processing tool 100 includes a base 110, a clamping mechanism 120, and a transmission assembly. The transmission assembly cooperates with the clamping mechanism 120 to convert linear motion into rotational motion, thereby achieving axial fixation of the metal profile 200 set on the base 110.

[0038] The base 110 at least includes a metal profile bearing area, and the metal profile bearing area is used to place a metal profile such as an aluminum profile;

[0039] The clamping mechanism 120 includes a clamping jaw 121, which includes a clamping jaw body 1211 that can rotate relative to the base 110, a clamping portion 1212 and a transmission portion 1213, the clamping portion 1212 and the transmission portion 1213 are respectively formed on the clamping jaw body 1211, and the transmission portion 1213 and the clamping jaw body 1212 are arranged on opposite sides of the rotation axis of the clamping jaw body 1211, the rotation axis of the clamping jaw body 1211 extends in the horizontal direction, and a sliding hole 12131 is formed on the transmission portion 1213;

[0040] The transmission assembly includes a transmission member 131 capable of linear displacement relative to the base 110, and the transmission member 131 has a partial structure passing through the sliding hole 12131, and the partial structure can be displaced in the sliding hole 12131;

[0041] The clamping mechanism 120 includes a clamping state and a releasing state. When the clamping mechanism 120 is in the clamping state, the aforementioned partial structure is located at a first position H1 in the sliding hole 12131. When the clamping mechanism 120 is in the releasing state, the aforementioned partial structure is located at a second position H2 in the sliding hole 12131. The first position H1 is different from the second position H2 and is respectively located on an extension line perpendicular to the axis of the sliding hole 12131.

[0042] In this example, if Figure 1 As shown, the base 110 includes a first area 111 and a second area 112 located on the outer peripheral side of the first area 111. The first area 111 is a metal profile bearing area, and the second area 112 is at least used to install a clamping mechanism 120. Specifically, the first area 111 is roughly circular, and the second area 112 is roughly annular surrounding the first area 111. The clamping mechanism 120 has a plurality of equally spaced distributions, which can be evenly distributed on the second area 112, for example, there can be three, and then three are arranged around the first area 111, and the angle between two adjacent ones is roughly 120°. Of course, in this case, the number of the clamping mechanisms 120 can also be 4, 5 or more.

[0043] In this example, the clamping jaw 121 is rotatably disposed on the base 110. When the clamping mechanism 120 is in a clamping state, the orthographic projection of the clamping portion 1212 of the clamping jaw 121 is at least partially located within the metal profile bearing area. Further, when the clamping mechanism 120 is in a released state, the orthographic projection of the clamping portion 1212 of the clamping jaw 121 is located outside the metal profile bearing area. Figures 1 to 5 As shown, when the clamping mechanism 120 is transformed into a clamping state, the clamping portion 1212 of the clamping jaw 121 rotates in a direction close to the first area 111 until it contacts the upper end of the metal profile 200 to achieve axial fixation. At this time, the orthographic projection of the clamping portion 1212 is partially located in the first area 111. When the clamping mechanism 120 is transformed into a releasing state, the clamping portion 1212 of the clamping jaw 121 rotates in a direction away from the first area 111 until it is separated from the upper end of the metal profile 200. When it is rotated to a sufficient angle, the metal profile 200 can be taken away. At this time, the orthographic projection of the clamping portion 1212 is located outside the first area 111.

[0044] In this example, a first rotating shaft hole 12111 is formed on the clamp body 1211, and the clamping mechanism 120 further includes a mounting seat 122 formed with a second rotating shaft hole 1221 and a rotating shaft 123, the rotating shaft 123 passes through the first rotating shaft hole 12111 and the second rotating shaft hole 1221 respectively, the mounting seat 122 is arranged on the base 110, and the clamp 121 is rotatably arranged by the rotating shaft 123. For details, see Figures 1 to 5 As shown, the mounting seat 122 is detachably mounted on the base 110 by bolts, and the mounting seat 122 can be two symmetrically arranged, so that the jaw body 1211 is more stable when it is rotatably arranged. The jaw body 1211 is rotatably arranged by the rotating shaft 123 and is supported on the mounting seat 122 by the rotating shaft 123, and the first rotating shaft hole 12111 is located in the middle of the jaw body 1211.

[0045] The axis of the sliding hole 12131 is arranged parallel to the axis of the rotating shaft 123, and the aforementioned partial structure of the transmission member 131 can be displaced in the sliding hole 12131 along a direction perpendicular to the axis of the sliding hole 12131; see Figures 4 to 5As shown, the sliding hole 12131 can be a waist-shaped hole, and a part of the structure of the transmission member 131 passes through the sliding hole 12131. When the transmission member 131 undergoes linear displacement, such as translational motion, the part of the structure is displaced in the sliding hole 12131 along the up-down direction. Of course, the actual displacement of the two is mutual. The horizontal height of the part of the structure does not change in the up-down direction. The displacement is actually achieved by the rotation of the sliding hole 12131 with the clamping jaw body 1211. It is precisely because the part of the structure can have freedom in the up-down direction in the sliding hole 12131 that it does not limit the rotation of the clamping jaw 121. Moreover, when the transmission member 131 undergoes translational motion, it can drive the transmission part 1213 to rotate, thereby realizing the rotation of the clamping jaw 121, that is, in this example, the linear motion of the transmission member 131 is converted into the rotational motion of the clamping jaw 121; further In actual operation, when the clamping structure 120 is to be clamped, the clamping portion 1212 needs to be rotated toward the first area 111 and downward, and the transmission portion 1213 needs to be moved away from the first area 111 and upward, that is, the transmission member 131 needs to be linearly moved away from the first area 111, and a part of the structure of the transmission member 131 will move toward the first position H1. When the clamping structure 120 is to be released, the clamping portion 1212 needs to be rotated away from the first area 111 and upward, and the transmission portion 1213 needs to be rotated toward the first area 111 and downward, that is, the transmission member 131 needs to be linearly moved toward the first area 111, and a part of the structure of the transmission member 131 will move toward the second position H2. Figure 4 As shown, the height of the first position H1 is lower than the height of the second position H2.

[0046] In this example, the transmission member 131 includes a first sub-transmission member 1311 that can be translated relative to the base 110, and a second sub-transmission member 1312 that passes through the sliding hole 12131. The second sub-transmission member 1312 is detachably connected to the first sub-transmission member 1311, and the second sub-transmission member 1312 can be cylindrical in shape; the first sub-transmission member 1311 is slidably arranged on the base 110, and a transmission ridge 13111 is formed at the bottom of the first sub-transmission member 1311. The design of the transmission ridge 13111 can be coordinated with the mechanism on the existing turning equipment. Specifically, the transmission ridge 13111 and the matching structure on the turning equipment, such as ridges, realize power transmission, so that when turning the metal profile, there is no need to set a separate driving mechanism for the fixed tooling, and the intensity of manual operation is also reduced.

[0047] In this example, a positioning protrusion 113 is provided on the base 110. The positioning protrusion 113 is located in the bearing area of ​​the metal profile. The positioning protrusion 113 can be used to position the metal profile and can also play a certain radial fixing role.

[0048] In this example, the clamp body 1211 , the clamping portion 1212 and the transmission portion 1213 are integrally formed.

[0049] See also Figure 5 As shown, when the metal profile processing tool 100 of this example clamps and fixes the metal profile 200, such as an aluminum profile, axial fixation is achieved from top to bottom.

[0050] In summary, based on the defects of the existing clamping tooling used in the metal profile processing process, such as being not conducive to turning and having high manual operation intensity, the inventor innovatively provides an improved tooling for metal profile processing, which can not only realize the clamping and fixing function of the metal profile but also reduce the negative impact on the processing of metal profiles such as aluminum profiles. Specifically, the tooling of the utility model can realize axial fixation to avoid the problem of difficult to balance the clamping force during radial fixation. The utility model converts the linear displacement of the transmission part into the rotational displacement of the clamping part through the cooperation of the transmission part on the clamping mechanism and the transmission part of the transmission assembly. The clamping part clamps or releases the metal profile during the forward and reverse rotation. The structure is simple and can realize axial fixation of the metal profile. The top-down fixation reduces the radial impact on the metal profile, such as reducing or even avoiding the deformation of metal profiles such as aluminum profiles, which is beneficial to turning the inside of the metal profile and ensuring excellent turning effect.
