Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clamping structures, and in particular relates to a clamping structure for laser cutting. Background Art
[0002] Laser cutting machines are widely used in industrial cutting processes. Laser beams are irradiated onto the surface of workpieces to make them reach melting or boiling points. At the same time, the gas coaxial with the beam blows away the melt. As the relative positions of the beam and the workpiece move, a slit is formed on the surface of the workpiece. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, and low processing costs, and can gradually replace traditional metal cutting process equipment.
[0003] At present, when laser cutting is performed on aluminum plates, the aluminum plates are basically fixed with clamps before laser cutting. The existing clamps generally fix the aluminum plates by means of clamps on both sides of the equipment, and the clamps are fixed relative to the equipment. As a result, after clamping, the aluminum plates cannot be adjusted in angle. When oblique cutting of the aluminum plates is required, the aluminum plates need to be re-clamped, resulting in low processing efficiency. Utility Model Content
[0004] The purpose of the utility model is to provide a clamping structure for laser cutting in view of the above-mentioned technical problems. After clamping the workpiece, the clamping structure can adjust the horizontal angle of the workpiece, thereby performing oblique cutting on the workpiece.
[0005] In view of this, the utility model provides a clamping structure for laser cutting, comprising two sets of clamping members.
[0006] Fixed base;
[0007] An adjusting base, the adjusting base is rotatably connected to the fixed base, and two sets of clamping parts are arranged on the adjusting base;

[0011] In this technical solution, the workpiece is clamped normally by two sets of clamps, and then a straight line is cut on the workpiece by a cutting laser. When the workpiece needs to be cut obliquely, the locking member is first controlled to allow the adjustable base and the fixed base to rotate. At this time, the adjustable base is rotated to the required angle in conjunction with the indicator rod and the arc-shaped scale bar reading, and then the locking member is controlled to limit the rotation of the adjustable base and the fixed base. At this time, the cutting laser still works according to the original cutting path, and an oblique line can be cut on the workpiece.
[0012] In the above technical solution, further, the locking member includes:
[0013] A mounting through hole, which is provided on the adjustment base, is coaxial with the rotation center of the adjustment base, passes through the upper and lower surfaces of the adjustment base, and a first locking member is provided on the side wall of the mounting through hole;
[0014] A fixed column, the fixed column is arranged on the fixed base, and the upper end of the fixed column passes through the mounting through hole and extends to the top of the adjustment base;
[0015] A sliding ring, the sliding ring is slidably connected to the fixed column, and a second locking member is provided on the outer wall of the sliding ring;
[0016] The first locking member and the second locking member can limit the rotation of the adjusting base when they are in contact with each other.
[0017] In the above technical solution, further, the first locking component is a plurality of toothed grooves spaced circumferentially on the side wall of the mounting through hole, and the second locking component is a plurality of toothed blocks spaced circumferentially on the outer wall of the sliding ring, and the toothed blocks can be inserted into the toothed grooves.

[0020] In the above technical solution, further, a bearing is provided on the fixed base, and the adjusting base is rotatably connected to the fixed base via the bearing.
[0021] The beneficial effects of the utility model are:
[0022] 1. By setting two sets of clamping parts on the adjustment base, and by designing the adjustment base to rotate with the fixed base to adjust the angle of the clamped workpiece, accurate angle adjustment is achieved by reading the arc scale bar and the indicator rod, and then the adjustment base and the fixed base are locked by the locking piece after the angle adjustment, so that the cutting laser can perform oblique cutting on the original cutting track.
[0023] 2. By installing the through hole, the first locking member, the fixed column, the sliding ring, and the second locking member, as long as the sliding ring is controlled to slide vertically on the fixed column, the locking and release of the adjustable base and the fixed base can be achieved, the operation is simple and the structure is stable.

It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0036] Example 1
[0037] like Figure 1-Figure 5 As shown, this embodiment provides a laser cutting clamping structure, including two sets of clamping parts 1, a fixed base 2, an adjustable base 3, an arc-shaped scale bar 4, an indicator rod 5, and a locking part;
[0038] The two sets of clamping members 1 can clamp the two ends of the workpiece. The structure of the clamping member 1 can be selected from the existing structure in the prior art. The structure of the clamping member 1 is not the design point of this embodiment and will not be described in detail here.
[0039] The fixed base 2 is the main part of this embodiment. The fixed base 2 has support legs and a working surface. The laser cutting structure can also be arranged on the fixed base 2. The laser cutting structure can select a common linear cutting laser on the market.
[0040] The adjusting base 3 is rotatably connected to the fixed base 2, and two sets of clamping members 1 are arranged on the adjusting base 3;
[0041] The arc-shaped scale bar 4 is arranged on the fixed base 2, and the arc-shaped scale bar 4 is marked with angle scale lines, angle values, zero point marks, etc.;
[0042] The indicator rod 5 is arranged on the adjustment base 3, and the end of the indicator rod 5 can extend to the arc-shaped scale bar 4, so as to cooperate with the arc-shaped scale bar 4 to quickly read the current angle value;
[0043] The locking member is used to lock the adjusting base 3 and the fixing base 2 when the adjusting base 3 is rotated to a suitable angle.
[0044] In this embodiment, the workpiece is clamped normally by two sets of clamping members 1, and then a straight line is cut on the workpiece by a cutting laser. When the workpiece needs to be cut obliquely, the locking member is first controlled to allow the adjustable base 3 and the fixed base 2 to rotate. At this time, the adjustable base 3 is rotated to the required angle in conjunction with the indicator rod 5 and the arc-shaped scale bar 4 readings, and then the locking member is controlled to limit the rotation of the adjustable base 3 and the fixed base 2. At this time, the cutting laser still works according to the original cutting path, and an oblique line can be cut on the workpiece.
[0045] Example 2
[0046] This embodiment provides a clamping structure for laser cutting, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a locking member;
[0047] See also Figure 4 and Figure 5 In this embodiment, the locking member includes: a mounting through hole 601, a fixing column 602, a sliding ring 603,
[0048] The mounting through hole 601 is provided on the adjusting base 3. The mounting through hole 601 is coaxial with the rotation center of the adjusting base 3. The mounting through hole 601 passes through the upper and lower surfaces of the adjusting base 3. A first locking member 6011 is provided on the side wall of the mounting through hole 601.
[0049] The fixing column 602 is disposed on the fixing base 2, and the upper end of the fixing column 602 passes through the mounting through hole 601 and extends to the upper side of the adjusting base 3;
[0050] The sliding ring 603 is slidably connected to the fixed column 602, and a second locking member 6031 is provided on the outer wall of the sliding ring 603;
[0051] In this embodiment, the first locking member 6011 and the second locking member 6031 can limit the rotation of the adjustment base 3 when they are in contact with each other. The cooperation between the first locking member 6011 and the second locking member 6031 is mainly used to limit the circumferential movement of the adjustment base 3. For example, the side wall of the mounting through hole 601 is a regular polygonal groove, and the outer wall of the sliding ring 603 is a regular polygon. When the two are in contact, each surface of the two regular polygonal structures is in contact at the same time, and the two cannot move relative to each other in the circumferential direction.
[0052] The length of the fixed column 602 is greater than the height of the adjustment base 3. When the sliding ring 603 slides to the upper part of the fixed column 602, it can be completely separated from the mounting through hole 601. When the sliding ring 603 slides downward, the second locking member 6031 can contact the first locking member 6011.
[0053] Specifically, when the clamping angle of the workpiece needs to be changed, the sliding ring 603 is slid upward on the fixed column 602 to separate the second locking component 6031 from the first locking component 6011. At this time, the adjustment base 3 and the fixed base 2 can be rotated to adjust the angle of the workpiece. After the adjustment is completed, the sliding ring 603 is slid downward on the fixed column 602 to make the second locking component 6031 contact with the first locking component 6011 to limit the rotation of the adjustment base 3.
[0054] Example 3
[0055] This embodiment provides a laser cutting clamping structure, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a first locking member 6011 and a second locking member 6031;
[0056] See also Figure 4 In this embodiment, the first locking member 6011 is a plurality of tooth-shaped grooves arranged at intervals along the circumferential direction on the side wall of the mounting through hole 601, and the second locking member 6031 is a plurality of tooth-shaped blocks arranged at intervals along the circumferential direction on the outer wall of the sliding ring 603, and the tooth-shaped blocks can be inserted into the tooth-shaped grooves; when the sliding ring 603 enters the mounting through hole 601, the tooth-shaped blocks can be inserted into the tooth-shaped grooves to limit the relative circumferential movement between the sliding ring 603 and the mounting through hole 601;
[0057] The number of tooth blocks can be the same as the number of tooth grooves, that is, one tooth block corresponds to one tooth groove. In addition, it can also be designed that multiple tooth blocks correspond to one tooth groove.
[0058] Example 4
[0059] This embodiment provides a laser cutting clamping structure, which, in addition to the technical solutions of the above embodiments, also discloses a connection structure between the sliding ring 603 and the fixed column 602;
[0060] See also Figure 3 and Figure 4 In this embodiment, a limiting strip 701 is provided on the outer wall of the fixed column 602 in the vertical direction, and a limiting groove 702 is provided on the inner wall of the sliding ring 603. The sliding ring 603 is slidably connected with the limiting strip 701 through the limiting groove 702. The length of the limiting strip 701 is greater than the length of the limiting groove 702. The limiting strip 701 is equivalent to a sliding track for the sliding ring 603 to slide on through the limiting groove 702. In this way, the circumferential angle deviation of the sliding ring 603 can be avoided during the sliding process on the fixed column 602.
[0061] In addition, the outer wall of the fixed column 602 can also be designed as a polygonal structure, and the inner wall of the sliding ring 603 is also designed as a corresponding polygonal structure, which can also limit the circumferential angle deviation of the sliding ring 603 during the sliding process on the fixed column 602.
[0062] Example 5
[0063] This embodiment provides a laser cutting clamping structure, which, in addition to the technical solutions of the above embodiments, also discloses an optimized connection between the adjustable base 3 and the fixed base 2;
[0064] See also Figure 5 In this embodiment, an arc-shaped slide groove 8 is provided on the fixed base 2, and the arc-shaped slide groove 8 is a track that limits the maximum adjustment angle. An arc-shaped block 9 is provided on the adjustment base 3, and the arc-shaped block 9 is slidably arranged in the arc-shaped slide groove 8;
[0065] In this way, the adjustment base 3 can be rotated within a certain angle, and the adjustment base 3 will not be rotated beyond the limited angle, and will not cause interference to other external devices.
[0066] Example 6
[0067] This embodiment provides a laser cutting clamping structure, which, in addition to the technical solutions of the above embodiments, also discloses a connection structure between the adjustable base 3 and the fixed base 2;
[0068] See also Figure 4 and Figure 5 A bearing 10 is provided on the fixed base 2, and the adjusting base 3 is rotatably connected to the fixed base 2 through the bearing 10, so that the rotational friction between the fixed base 2 and the adjusting base 3 can be reduced, which is conducive to the angle adjustment of the workpiece.
