Description

Technical Field

[0001] This utility model relates to the technical field of window frame production, and in particular to a clamping mechanism and an aluminum profile sawing machine. Background Technology

[0002] In the construction industry, aluminum alloy profiles are one of the materials used for fireproof window frames, resulting in a large and continuous demand for them. To manufacture window frames that meet different specifications and design requirements, aluminum profiles need to be sawn into suitable lengths and shapes. Sawing is a crucial step in the aluminum profile processing flow, with the sawing machine responsible for cutting the profiles to specific lengths and dimensions. In actual large-scale production scenarios, to meet increasing order demands and improve production efficiency, it is often necessary to cut multiple aluminum profiles simultaneously.

[0003] However, existing aluminum profile sawing machines have the following shortcomings in practical use: when cutting multiple aluminum profiles simultaneously, the clamping mechanism on existing aluminum profile sawing machines usually requires at least two cylinders or at least two clamps to clamp the aluminum profiles from both above and the side. In other words, at least two independent actions are needed to effectively clamp the aluminum profiles. This not only makes the clamping process cumbersome and complex but also consumes a significant amount of time, resulting in low efficiency throughout the entire cutting production process. Therefore, this application proposes a clamping mechanism and an aluminum profile sawing machine. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a clamping mechanism and aluminum profile sawing machine that can complete the clamping operation from both the top and side of the aluminum profile in one action, thereby improving the efficiency of the cutting production process.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A clamping mechanism, comprising:

[0007] Frame; and

The clamping drive is mounted on the upright frame, the support base is mounted on the output shaft of the clamping drive, the top plate passes through the support base, and the elastic element is sleeved on the top plate. The elastic element pushes against the support base and the top plate respectively. One end of the side pusher is rotatably connected to the top plate, and the middle position of the side pusher is rotatably connected to the support base. The clamping drive drives the support base to move downward, and the elastic element pushes the top plate closer to the upper surface of the aluminum profile. The support base drives the end of the side pusher away from the top plate to approach the side of the aluminum profile, so that the top plate and the side pusher together clamp the aluminum profile.

The pressure block drives the end of the push rod away from the connecting rod to approach the aluminum profile.

[0013] Optionally, the push rod has an arc-shaped portion at the end away from the connecting rod, and the arc-shaped portion abuts against the aluminum profile.

[0014] Optionally, the clamping assembly further includes a slider, which is disposed on the upright and has a groove. The pressure block also has a slide rail, which engages with the groove. The push block drives the pressure block to slide downward along the groove.

[0034] like Figures 1 to 5In one embodiment, a clamping mechanism 10 includes a stand 11 and a clamping assembly 12. The clamping assembly 12 includes a clamping drive 121, a support base 122, a top plate 123, a side pusher 124, and an elastic member 125. The clamping drive 121 is mounted on the stand 11, the support base 122 is mounted on the output shaft of the clamping drive 121, the top plate 123 passes through the support base 122, and the elastic member 125 is sleeved on the top plate 123. The elastic member 125 pushes the top plate 124 and pushes the top plate 125. The top support 122 and the top plate 123 are connected. One end of the side pusher 124 is rotatably connected to the top plate 123, and the middle position of the side pusher 124 is rotatably connected to the support 122. The clamping drive 121 drives the support 122 to move downward. The elastic member 125 pushes the top plate 123 close to the upper surface of the aluminum profile. The support 122 drives the side pusher 124 away from the top plate 123 to approach the side of the aluminum profile, so that the top plate 123 and the side pusher 124 clamp the aluminum profile together.

[0035] It should be noted that the clamping drive 121 is mounted on the upright 11. For example, the clamping drive 121 is a downward-pressing cylinder structure, and the output shaft of the clamping drive 121 passes downward through the upright 11. Furthermore, the support base 122 tends to have a U-shaped structure, and the output shaft of the clamping drive 121 is connected to the middle position of the support base 122. Furthermore, two top plates 123 are provided, each passing vertically upward through opposite ends of the support base 122, allowing the two top plates 123 to move up and down relative to the support base 122. Furthermore, an elastic element 125 is sleeved on the top plate 123. The elastic element 125 is a spring structure, and it is located between the top plate 123 and the support base 122, allowing the elastic element 125 to push the top plate 123 away from the support base 122. One end of the side pusher 124 is rotatably connected to the side of the top plate 123 facing the support base 122, and the middle position of the side pusher 124 is rotatably connected to the end of the support base 122, so that the end of the side pusher 124 away from the top plate 123 is centered on the end of the support base 122 and away from the top plate 123. Furthermore, when the top plate 123 is in contact with the aluminum profile, as the clamping drive 121 continues to drive the support seat 122 to press the elastic member 125, the support seat 122 will drive the side pusher 124 away from the top plate 123 to approach the top plate 123. In this way, the clamping drive 121 drives the support seat 122 downward to make the top plate 123 press the aluminum profile, and at the same time, the support seat 122 drives the side pusher 124 with the top plate 123 as the fulcrum, so that the side pusher 124 away from the top plate 123 approaches the side of the top plate 123, so that the top plate 123 and the side pusher 124 clamp the aluminum profile from the top and the side respectively.

[0036] It should be noted that there are two top plates 123, which are located on opposite sides of the support base 122. There are also two side pushers 124, which are located on opposite sides of the support base 122.

[0037] like Figures 1 to 5 As shown, in one embodiment, the support base 122 includes a push block 1221 and a pressure block 1222. One end of the push block 1221 is disposed on the output shaft of the clamping drive member 121, the pressure block 1222 is disposed on the push block 1221, and the top plate 123 passes through the pressure block 1222.

[0038] It should be noted that the push block 1221 tends to have a U-shaped structure, and there are two pressure blocks 1222, which are respectively disposed on the two opposing sides of the push block 1221. Furthermore, the pressure block 1222 has a through hole, which is opened in a vertically downward direction. The top plate 123 passes through the through hole, so that the top plate 123 can move up and down relative to the pressure block 1222.

[0039] like Figures 1 to 4 As shown, in one embodiment, a sliding column 1231 is provided on the top plate 123. The end of the sliding column 1231 away from the top plate 123 passes through the pressure block 1222. An elastic member 125 is sleeved on the sliding column 1231. The elastic member 125 pushes the top plate 123 and the pressure block 1222 respectively.

[0040] It should be noted that two sliding pillars 1231 are provided on one top plate 123, and both sliding pillars 1231 are located on the side of the top plate 123 facing the pressure block 1222. One end of the two sliding pillars 1231 is connected to the top plate 123, and the other end of the two sliding pillars 1231 extends out from the side of the pressure block 1222 away from the top plate 123 through a through hole. Multiple elastic elements 125 are provided, and each elastic element 125 is respectively fitted onto each sliding pillar 1231, and each elastic element 125 is located between the top plate 123 and the pressure block 1222, so that each elastic element 125 simultaneously pushes the pressure block 1222 and the top plate 123, so that the side of the top plate 123 away from the pressure block 1222 abuts against the upper surface of the aluminum profile. Furthermore, each sliding column 1231 is provided with a limiting block on the end away from the top plate 123. Since the end of the sliding column 1231 away from the top plate 123 extends through the through hole from the end of the pressure block 1222 away from the top plate 123, the limiting block is located on the side of the pressure block 1222 away from the top plate 123. Thus, when each elastic element 125 pushes away from the pressure block 1222, each limiting block abuts against the end of the pressure block 1222 away from the top plate 123, thereby preventing the top plate 123 from sliding off the pressure block 1222.

[0041] like Figures 1 to 2 , Figure 5As shown, in one embodiment, the pressure block 1222 has a groove, one end of the side pusher 124 passes through the groove and is rotatably connected to the top plate 123, and the middle position of the side pusher 124 is rotatably connected to the pressure block 1222.

[0042] It should be noted that a groove is provided on the end of the pressure block 1222. One end of the side pusher 124 passes through the groove and is rotatably connected to the side of the top plate 123 near the pressure block 1222. The middle position of the side pusher 124 is rotatably connected to the end of the pressure block 1222. When each elastic member 125 pushes the top plate 123 away from the pressure block 1222, the top plate 123 drives the side pusher 124 to rotate around the end of the pressure block 1222, causing the end of the side pusher 124 extending away from the top plate 123 to swing closer to the side of the aluminum profile.

[0043] like Figures 1 to 4 As shown, in one embodiment, the side pusher 124 includes a connecting rod 1241 and a push rod 1242. One end of the connecting rod 1241 passes through a groove and is rotatably connected to the top plate 123. The other end of the connecting rod 1241 is rotatably connected to the push rod 1242. The middle position of the push rod 1242 is rotatably connected to the pressure block 1222. The pressure block 1222 drives the end of the push rod 1242 away from the connecting rod 1241 to approach the aluminum profile.

[0044] It should be noted that one end of the connecting rod 1241 is rotatably connected to the side of the top plate 123 facing the pressure block 1222, and the middle position of the push rod 1242 is rotatably connected to the end of the pressure block 1222 located in the groove, so that the middle position of the connecting rod 1241 is located in the groove. Thus, when the elastic element 125 pushes the top plate 123 away from the pressure block 1222, the top plate 123 causes the two ends away from the push rod 1242 to swing downward, causing the connecting rod 1241 to drive the push rod 1242 to rotate around the end of the pressure block 1222, thereby causing the end of the push rod 1242 away from the connecting rod 1241 to rotate away from the top plate 123. Furthermore, when the pressure block 1222 drives the top plate 123 to press down on the multiple aluminum profiles, the top plate 123 abuts against the multiple aluminum profiles, preventing the elastic element 125 from pushing the top plate 123 downward and keeping the top plate 123 stationary. This causes the pressure block 1222 to move downward closer to the top plate 123, gradually reducing the gap between the pressure block 1222 and the top plate 123. Consequently, the vertical distance between the side pusher 124 and the two connection points between the top plate 123 and the pressure block 1222 also gradually decreases. When the pressure block 1222 moves downward, the connecting rod 1241 uses the connection point of the top plate 123 as a fulcrum, pushing the push rod 1242 away from the pressure block 1222 with the connection point of the pressure block 1222 as the center. This causes the pressure block 1222 to drive the push rod 1242 away from the connecting rod 1241 towards the top plate 123, so that the push rod 1242 abuts against the side of the aluminum profile. Thus, the top plate 123 and the push rod 1242 together clamp multiple aluminum profiles. Therefore, when the clamping drive 121 drives the pressure block 1222 downwards, the pressure block 1222 first drives the top plate 123 to press the multiple aluminum profiles from top to bottom, and then the pressure block 1222 drives the push rod 1242 to push the multiple aluminum profiles from the side. This allows the clamping mechanism and aluminum profile saw 1 of this application to complete the clamping operation of multiple aluminum profiles from both the top and side with only one downward movement, thereby improving the production efficiency of cutting.

[0045] As shown in the figure Figures 1 to 4 As shown, in one embodiment, the push rod 1242 has an arc-shaped portion on the end away from the connecting rod 1241, and the arc-shaped portion abuts against the aluminum profile.

[0046] It should be noted that the curved part is located on the side of the push rod 1242 facing the top plate 123. When it is necessary to clamp aluminum profiles of various shapes, the curved part can firmly abut against the aluminum profiles of various shapes.

[0047] like Figure 1As shown, in one embodiment, an aluminum profile sawing machine 20 includes a frame 21 and a cutting assembly 22. The frame 21 has a cutting hole 211 located below the clamping drive member 121. The upright frame 11 is mounted on the frame 21. The cutting assembly 22 includes a pushing drive member 221, a rotating drive member 222, and a cutting blade 223. The pushing drive member 221 is mounted on the frame 21. The rotating drive member 222 is slidably mounted on the pushing drive member 221. The cutting blade 223 is mounted on the rotating drive member 222 and extends out of the cutting hole 211. The rotating drive member 222 drives the cutting blade 223 to rotate, and the pushing drive member 221 drives the cutting blade 223 to slide within the cutting hole 211.

[0048] It should be noted that a cutting hole 211 is provided on the table surface of the frame 21, and the cutting hole 211 has an elongated hole structure. One end of the upright 11 is set on the table surface of the frame 21, and the other end of the upright 11 extends above the cutting hole 211. The clamping drive 121 is set on the end of the upright 11 away from the frame 21, so that the clamping drive 121 can be positioned above the cutting hole 211 to drive the support 122 to move closer to or away from the cutting hole 211.

[0049] It should be noted that the push-up drive 221 is mounted on the frame 21 and is located below the cutting hole 211. For example, the push-up drive 221 is a push cylinder, with one end mounted on the frame 21, and its output shaft connected to a rotary drive. Furthermore, the rotary drive 222 is slidably mounted on the frame 21 and is located below the cutting hole 211. For example, the rotary drive 222 is a motor structure. This allows the push-up drive 221 to push the rotary drive 222 to slide relative to the frame 21. Furthermore, the cutting disc 223 is a circular disc structure, with its axis positioned on the output shaft of the rotary drive 222, allowing the rotary drive 222 to rotate the cutting disc 223. The rotating drive 222 drives the cutting disc 223 to extend from above the cutting hole 211. When the pushing drive 221 drives the rotating drive 222 to slide on the frame 21, the rotating drive 222 drives the cutting disc 223 to rotate while simultaneously causing the cutting disc 223 to move back and forth within the cutting hole 211.

[0050] like Figure 1 As shown, in one embodiment, the cutting assembly 22 further includes a side plate 224, which is disposed on the frame 21 and located below the clamping assembly 12. The side plate 224 is used for positioning aluminum profiles.

[0051] It should be noted that the side plate 224 is set on the table of the frame 21, and one side of the side plate 224 is in contact with the upright frame 11, so that the push rod 1242 pushes multiple aluminum profiles to abut against the side plate 224, thereby making the push rod 1242 and the side plate 224 jointly clamp the multiple aluminum profiles horizontally. The pressure block 1222 drives the top plate 123 to abut against the multiple aluminum profiles downward, so that the top plate 123 and the table of the frame 21 jointly clamp the multiple aluminum profiles vertically. In this way, multiple aluminum profiles can be fixed on the aluminum profile saw 20. Furthermore, the side plate 224 is located in the middle of the cutting hole 211, and the side plate 224 is perpendicular to the extension direction of the cutting hole 211, so that the push rod 1242 pushes multiple aluminum profiles perpendicular to the cutting hole 211, thereby enabling the cutting blade 223 to cut multiple aluminum profiles simultaneously along the extension direction of the cutting hole 211, thereby improving the cutting efficiency.

[0052] like Figure 1 As shown, in one embodiment, a clearance groove is provided on the side plate 224, and the clearance groove is connected to the cutting hole 211.

[0053] It should be noted that the clearance groove is perpendicular to the cutting hole 211 and is connected to the cutting hole 211. When the push rod 1242 pushes multiple aluminum profiles close to the side plate 224, the part of the cutting blade 223 that extends out of the cutting hole 211 can pass through the clearance groove and move between the two ends of the cutting hole 211 to cut the multiple aluminum profiles.

[0054] like Figure 1 As shown, in one embodiment, the clamping assembly 12 further includes a slider 126, which is disposed on the stand 11. The slider 126 has a groove 1261, and the pressure block 1222 also has a slide rail. The slide rail is engaged with the groove 1261, and the push block 1221 drives the pressure block 1222 to slide downward along the groove 1261.

[0055] It should be noted that there are two sliders 126, both of which are vertically upward mounted on the frame 21, and one side of each slider 126 is screwed to the opposite side of the upright 11. Furthermore, each slider 126 has a groove 1261 on its side adjacent to the upright 11, extending vertically upward from one end of the slider 126 to the other, such that the direction of the groove 1261 is consistent with the direction of movement of the clamping drive 121 pushing the support 122. Furthermore, a slide rail is provided on the end of the pressure block 1222 away from the groove. The slide rail engages with the slide groove 1261, so that when the clamping drive 121 drives the support base 122 to move up and down, the support base 122 drives the pressure block 1222 to move up and down along the slider 126. In this way, when the pressure block 1222 drives the top plate 123 to abut against multiple aluminum profiles, the pressure block 1222 and the side plate 224 maintain a right angle, so that the clamping assembly 12 can firmly fix multiple aluminum profiles on the frame 21.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
