Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and more specifically, to a profile processing fixture. Background Technology

[0002] Metal profiles are objects with specific geometric shapes made of iron or steel, or other materials with a certain strength and toughness, through processes such as rolling, extrusion, and casting. These materials have fixed external dimensions, a specific cross-sectional shape, and specific mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products, and are commonly used in building structures and manufacturing installations.

[0003] Profiles often require positioning and clamping during processing. However, in the prior art, such as the general-purpose profile processing fixture disclosed in CN207873712U, a bracket, a fixture table, a screw, a motor, and a cylinder are provided. The fixture table is arranged above the bracket, and a slide rail is arranged inside the fixture table. A slider is arranged inside the slide rail. A fixed clamping plate is arranged above the fixture table. A connecting plate is arranged on the fixture table away from the fixed clamping plate. The cylinder is arranged above the connecting plate. A movable clamping plate is arranged near the fixed clamping plate of the cylinder.

[0004] However, when using the above-mentioned general-purpose clamps to fix certain profiles with special shapes, the left and right sides cannot effectively contact the profile plane, making it impossible to clamp stably and making it inconvenient for subsequent processing of irregular profiles. Utility Model Content

[0005] Therefore, in order to solve the problem of being unable to stably clamp profiles with special shapes, this utility model provides a profile processing fixture, the specific technical solution of which is as follows:

[0006] A profile processing fixture includes a pressing mechanism and a clamping device. The pressing mechanism includes a bracket and a limiting pressing head. The limiting pressing head is slidably mounted on the bracket and can be raised and lowered relative to the bracket. The bottom of the limiting pressing head is provided with a contact pad. The clamping device includes a positioning plate and a first clamping member and a second clamping member for cooperating in clamping the profile. The positioning plate is disposed below the limiting pressing head. The first clamping member and the second clamping member are respectively mounted on both ends of the positioning plate and are arranged facing each other. The first clamping member can slide relative to the positioning plate. Both the first clamping member and the second clamping member are rotatably equipped with an abutment structure, and the abutment structure is provided with anti-slip protrusions.

[0007] The aforementioned profile processing fixture features a limiting pressure head that reciprocates to approach the profile, thus securing it from the top. A contact pad prevents scratches and wear when the limiting pressure head collides directly with the profile, providing protection. An abutment structure allows for adjustment of the clamping position, adapting to profiles of different sizes and shapes, solving the problem of unstable clamping for profiles with unusual shapes. Anti-slip protrusions increase friction during contact with the profile, improving stability during clamping.

[0008] Furthermore, the pressing mechanism also includes a lifting cylinder, which is mounted on the top of the bracket, and the output end of the lifting cylinder passes through the bracket and is connected to the limiting pressing head in a transmission connection.

[0009] Furthermore, the pressing mechanism also includes a movable seat and a lifting rod. The movable seat is inserted into the bracket, one end of the lifting rod is movably connected to the inner cavity of the movable seat, and the other end of the lifting rod is fixedly connected to the limiting pressing head.

[0010] Furthermore, the inner wall of the movable seat is fixed with multiple limiting blocks at intervals, and each of the multiple limiting blocks abuts against the outer surface of the lifting rod; the bottom of the inner wall of the movable seat is provided with a limiting ring, and the limiting ring is provided with an arc chamfer for the lifting rod to pass through.

[0011] Furthermore, the limiting pressure head includes a connecting plate, a disassembly component, and a pressure head body. The top of the connecting plate has a first insertion hole and a second insertion hole. The output end of the lifting cylinder is inserted into the first insertion hole, and the lifting rod is inserted into the second insertion hole. One end face of the disassembly component is fixed to the bottom of the connecting plate, and the other end face of the disassembly component is detachably connected to the pressure head body. The contact pad is disposed on the pressure head body.

[0012] Furthermore, the profile processing fixture also includes a mounting base, the bracket is fixed on the mounting base, the mounting base is provided with a guide rail and a drive cylinder, a slide plate is slidably mounted on the guide rail, the output end of the drive cylinder is connected to the slide plate and used to control the sliding of the slide plate, and the positioning plate is threadedly mounted on the slide plate.

[0013] Furthermore, the clamping device also includes a moving component, which includes a control handle, a slider, and a lead screw rotatably mounted on one end of the positioning plate. The control handle is sleeved on one end of the lead screw, and the other end of the lead screw is threadedly connected to the slider. The slider is fixed to the bottom of the first clamping member, and the second clamping member is fixedly mounted on the other end of the positioning plate.

[0014] Furthermore, the structure of the first clamping member is the same as that of the second clamping member, and an arc-shaped sliding groove is provided inside the first clamping member.

[0015] Furthermore, the abutment structure includes multiple mounting blocks and an arc-shaped block slidably disposed within the arc-shaped groove.

[0027] like Figures 1-3 As shown, a profile processing fixture in one embodiment of the present invention includes a pressing mechanism and a clamping device. The pressing mechanism includes a bracket 1 and a limiting pressure plate and a limiting pressure head 2. The limiting pressure plate and the limiting pressure head 2 are slidably mounted on the bracket 1 and can be raised and lowered relative to the bracket 1. The bottom of the limiting pressure head 2 is provided with a contact pad 21. The clamping device includes a positioning plate 3 and a first clamping member 4 and a second clamping member 5 for cooperating in clamping the profile. The positioning plate 3 is disposed below the limiting pressure head 2. The first clamping member 4 and the second clamping member 5 are respectively mounted on both ends of the positioning plate 3 and are arranged facing each other. The first clamping member 4 can slide relative to the positioning plate 3. Both the first clamping member 4 and the second clamping member 5 are rotatably equipped with an abutment structure 6, and the abutment structure 6 is provided with an anti-slip protrusion 61.

[0028] The aforementioned profile processing fixture, by setting a limiting pressure plate and limiting pressure head 2, allows the limiting pressure plate and limiting pressure head 2 to reciprocate and approach the profile, thereby achieving limiting and fixing of the profile from the top; by setting a contact pad 21, when the limiting pressure plate and limiting pressure head 2 directly collide with the profile, it can effectively prevent the profile from being scratched or worn, thus providing a certain degree of protection for the profile; by setting a stop structure 6, the rotation of the stop structure 6 can adjust the clamping position of the profile, thereby adapting to profiles of different sizes or shapes, solving the problem of not being able to stably clamp profiles with special shapes; by setting an anti-slip protrusion 61, the friction when in contact with the profile is increased, improving the stability of the profile during the clamping process.

[0029] like Figure 1 and Figure 2As shown, in one embodiment, the pressing mechanism further includes a lifting cylinder 11, which is mounted on the top of the bracket 1. The output end of the lifting cylinder 11 passes through the bracket 1 and is connected to the limiting pressing head 2 via a transmission connection. By providing the lifting cylinder 11, the lifting cylinder 11 drives the lifting movement of the limiting pressing head 2, thereby enabling the limiting pressing head to reciprocate against the top of the profile, thus completing the limiting of the profile.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the pressing mechanism further includes a movable seat 12 and a lifting rod 13. The movable seat 12 is inserted into the bracket 1, one end of the lifting rod 13 is movably connected to the inner cavity of the movable seat 12, and the other end of the lifting rod 13 is fixedly connected to the limiting pressing head 2.

[0031] like Figure 4 As shown, in one embodiment, the inner wall of the movable seat 12 is fixed with multiple limiting blocks 121 at intervals, and each limiting block 121 abuts against the outer surface of the lifting rod 13; a limiting ring is provided at the bottom of the inner wall of the movable seat 12, and the limiting ring has an arc chamfer 122 for the lifting rod 13 to pass through. In this way, by setting the limiting blocks 121, the lifting rod 13 is limited; by setting the arc chamfer 122, the lifting rod 13 is effectively corrected, so that the lifting rod 13 can remain in a vertical state.

[0032] In one embodiment, the limiting pressure head 2 includes a connecting plate, a disassembly component, and a pressure head body. The top of the connecting plate has a first insertion hole and a second insertion hole. The output end of the lifting cylinder 11 is inserted into the first insertion hole, and the lifting rod 13 is inserted into the second insertion hole. One end face of the disassembly component is fixed to the bottom of the connecting plate, and the other end face of the disassembly component is detachably connected to the pressure head body. The contact pad 21 is disposed on the pressure head body.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the profile processing fixture further includes a mounting base 7. A bracket 1 is fixed to the mounting base 7. The mounting base 7 is provided with a guide rail 71 and a drive cylinder 72. A slide plate 73 is slidably mounted on the guide rail 71. The output end of the drive cylinder 72 is connected to the slide plate 73 and used to control the sliding of the slide plate 73. A positioning plate 3 is threaded onto the slide plate 73. By providing the drive cylinder 72, the drive cylinder 72 drives the slide plate 73 to slide on the guide rail 71, thereby adjusting the position of the clamping device on the slide plate 73.

[0034] Specifically, the guide rail 71 is set in a horizontal direction.

[0035] like Figure 2 and Figure 3As shown, in one embodiment, the clamping device further includes a moving component 8. The moving component 8 includes a control handle 81, a slider 82, and a lead screw 83 rotatably mounted on one end of the positioning plate 3. The control handle 81 is sleeved on one end of the lead screw 83, and the other end of the lead screw 83 is threadedly connected to the slider 82. The slider 82 is fixed to the bottom of the first clamping member 4, and the second clamping member 5 is fixedly mounted on the other end of the positioning plate 3. By providing the control handle 81, the operator can operate the control handle 81 to drive the lead screw 83 to rotate on the positioning plate 3, thereby enabling the first clamping member 4 to reciprocate and adjust the clamping gap between the first clamping member 4 and the second clamping member 5, which is beneficial for adapting to profiles of different sizes.

[0036] In one embodiment, the structure of the first clamping member 4 is the same as that of the second clamping member 5, and the first clamping member 4 has an arc-shaped sliding groove.

[0037] like Figure 3 As shown, in one embodiment, the abutment structure 6 includes a plurality of mounting blocks 62 and an arc-shaped block 63 slidably disposed in an arc-shaped groove. The arc-shaped inner wall of the arc-shaped groove is adapted to the arc-shaped outer surface of the arc-shaped block 63. The plurality of mounting blocks 62 are respectively spaced out on the arc-shaped block 63, and each mounting block 62 is spaced out with a plurality of anti-slip protrusions 61.

[0038] like Figure 3 As shown, in one embodiment, the surface of the anti-slip protrusion 61 that abuts against the profile is provided with a concave-convex anti-slip groove 611. The surface of the concave-convex anti-slip groove 611 is coated with anti-slip particles to increase the friction between the surface of the anti-slip protrusion 61 and the profile.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] 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.
