[0004] The aforementioned prior art reduces the resistance of the slider moving in the groove by setting the connecting pad and the metal ball, and avoids the wear caused by long-term friction between the moving block and the fixture body, thereby enabling the tooling fixture for CNC machine tool machining center to be used better, and thus improving the performance of the tooling fixture for CNC machine tool machining center.

[0005] Based on the search of the aforementioned patents and the findings of existing technologies, it is found that the overall structure of the aforementioned fixture is too simple when in use, which can easily lead to unstable clamping when clamping workpieces, affecting the clamping stability of the workpieces. Therefore, this utility model proposes a dual-station profile machining center fixture mechanism that can stably clamp and clamp different sizes. Utility Model Content

[0006] The purpose of this invention is to provide a fixture mechanism for a dual-station profile machining center to solve the problems mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model uses side limiting posts on both sides to limit the left and right movement of the square profile being clamped. This allows the profile to be clamped and limited from both sides, preventing it from moving left and right, and providing a clamping and fixing effect in the left and right direction.

[0016] The side limiting posts on both sides can move relative to each other under the action of the above-mentioned threaded drive structure, thereby changing the distance between the two side limiting posts.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides an embodiment of a dual-station profile machining center fixture mechanism, including an assembly plate 1, a fixture table 3 above the assembly plate 1, guide grooves 4 on both sides of the upper surface of the fixture table 3, bearing seats 5 fixedly installed on both sides of the upper surface of the assembly plate 1, a primary lead screw 6 rotatably connected between the two bearing seats 5, the primary lead screw 6 is a positive and negative screw, threaded slides 8 are threadedly connected to the positive and negative threads of the primary lead screw 6, and side limit posts 9 are fixedly installed on the upper surface of the two threaded slides 8. In order to drive the primary lead screw 6 to rotate, a motor seat is installed on one side of the outer wall of the assembly plate 1, a primary motor 7 is fixedly installed on the outer wall of the motor seat, and the output shaft of the primary motor 7 is connected to the primary lead screw 6 through a coupling.

[0028] Based on the above structure, the present invention uses a primary motor 7 to drive a primary lead screw 6 to rotate clockwise or counterclockwise via its output shaft and coupling. Since the primary lead screw 6 is a positive and negative screw, when the primary lead screw 6 rotates clockwise or counterclockwise, the two threaded slides 8 connected to it will move relative to each other, that is, the two threaded slides 8 will move away from each other or move closer to each other. When the two threaded slides 8 move relative to each other, they can synchronously drive the side limit posts 9 on both sides to move relative to each other, thereby changing the distance between the two side limit posts 9.

[0029] In actual use, the side limiting posts 9 on both sides can limit the left and right movement of the clamped square profile. In this way, the side limiting posts 9 on both sides can limit and clamp the profile on both sides, preventing the profile from moving left and right, and achieving a clamping and fixing effect in the left and right direction.

[0030] The side limiting posts 9 on both sides can move relative to each other under the action of the above-mentioned threaded drive structure, thereby changing the distance between the two side limiting posts 9. By dynamically adjusting the distance between the side limiting posts 9, it can be used to clamp square profiles of different lengths. It can meet the left and right clamping work of profiles of different lengths within a certain length adjustment range, and has good length size applicability, thus improving the overall applicability of this utility model clamp.

[0031] In this embodiment, in order to fix and clamp the profile at the front and back, the side limiting post 9 passes through the guide groove 4 of the clamping table 3 and is fixedly installed with the upper guide plate 10. The upper guide plate 10 is perpendicular to the first-stage lead screw 6. The upper guide plate 10 has a linear guide groove 11 inside. The second-stage lead screw 12 is rotatably installed in the linear guide groove 11 through the bearing. The second-stage lead screw 12 is a positive and negative screw. Threaded blocks 14 are threaded on both the positive and negative threads of the second-stage lead screw 12. Side clamping claws 15 are fixedly installed on the outer walls of the two threaded blocks 14. Clamping blocks 16 are fixedly installed on the outer wall of the opposite side of each side clamping claw 15.

[0032] Furthermore, in order to drive the secondary lead screw 12 to rotate, a secondary motor 13 is fixedly installed on the outer wall of the ends of the two upper guide plates 10, and the output shaft of the secondary motor 13 is connected to the corresponding secondary lead screw 12 through a coupling.

[0033] This structural design is the same as the threaded transmission principle of the first group mentioned above. That is, after the side limiting post 9 clamps the left and right sides of the square profile, the secondary motor 13 can drive the secondary screw 12 to rotate. Since the secondary screw 12 is also a forward and reverse screw, when the secondary screw 12 rotates clockwise or counterclockwise, the two threaded blocks 14 connected to it will move relative to each other. In this way, the relative movement of the two threaded blocks 14 can drive the two opposite side jaws 15 on the same side to move relative to each other.

[0034] When the two side grippers 15 approach each other, they can use the gripping block 16 to clamp the square profile between them from the front and back. This, combined with the aforementioned side limiting post 9, allows the clamping mechanism of this invention to perform left-right and front-back limiting clamping of the square profile. The specific clamping state is shown in the appendix to the instruction manual. Figure 1 As shown, the white board between the four side clamps 15 is the square profile;

[0035] Meanwhile, the two opposing side jaws 15 of this utility model can be dynamically adjusted in distance through the action of the second set of threaded drive structure. This allows the side jaws 15 of this utility model to meet the clamping requirements for different width dimensions under dynamic adjustment, and has a good width adjustment effect, meeting the width requirements of different square profiles.

[0036] In this embodiment, in order to improve the structural connection between the assembly plate 1 and the fixture table 3, upper columns 2 are fixedly installed at the four corners of the upper surface of the assembly plate 1, and the tops of the four upper columns 2 are fixedly connected to the lower surface of the fixture table 3.

[0037] In this embodiment, in order to improve the linear displacement guidance of the two threaded slide blocks 8 and maintain the linear displacement effect, linear guide rails 17 are fixedly installed on both sides of the first-stage lead screw 6 and on the upper surface of the assembly plate 1. The linear guide rails 17 are limited and slidably connected to the two threaded slide blocks 8, so that the linear guide rails 17 can provide a certain displacement guidance for the relative movement of the two threaded slide blocks 8.

[0038] Working principle: When in use, the clamping mechanism of this utility model can be equipped with two clamping mechanisms of this utility model and installed in a suitable dual-station profile processing center, thereby achieving the actual use effect of dual-station clamping.

[0039] It should be noted that the clamping mechanism of this utility model is only applicable to the clamping of square profiles and cannot be applied to the clamping of round profiles.

[0040] When clamping the square profile, the square profile can be placed between the two side limiting posts 9 and between the four side clamps 15.

[0041] The device can then operate via the primary motor 7. The primary motor 7 can drive the primary lead screw 6 to rotate clockwise or counterclockwise via its output shaft and coupling. Since the primary lead screw 6 is a positive and negative screw, when the primary lead screw 6 rotates clockwise or counterclockwise, the two threaded slide blocks 8 connected to it will move relative to each other, that is, the two threaded slide blocks 8 will move away from each other or move closer to each other. When the two threaded slide blocks 8 move relative to each other, they can synchronously drive the side limit posts 9 on both sides to move relative to each other.

[0042] When the two side limiting posts 9 approach each other, they can clamp and fix the profile between them from the side. In this way, the side limiting posts 9 on both sides can limit and clamp the profile on both sides, preventing the profile from moving left and right, and have a clamping and fixing effect in the left and right direction.

[0043] After the side limit post 9 is fixed and clamped, the two secondary motors 13 operate. At this time, the secondary motors 13 can drive the secondary lead screw 12 to rotate. Since the secondary lead screw 12 is also a forward and reverse screw, when the secondary lead screw 12 rotates clockwise or counterclockwise, the two threaded blocks 14 connected to it will move relative to each other. In this way, the relative movement of the two threaded blocks 14 can drive the two opposite side jaws 15 on the same side to move relative to each other.

[0044] When the two side grippers 15 approach each other, they can use the gripping block 16 to clamp the square profile between them from the front and back. This, combined with the aforementioned side limiting post 9, allows the clamping mechanism of this invention to perform left-right and front-back limiting clamping of the square profile. The specific clamping state is shown in the appendix to the instruction manual. Figure 1 As shown, the white board between the four side clamps 15 is the square profile.

[0045] In actual use, the side limiting posts 9 on both sides can limit the left and right movement of the clamped square profile. Thus, the side limiting posts 9 on both sides can limit and clamp the profile on both sides, preventing the profile from moving left and right, and achieving a clamping and fixing effect in the left and right direction.

[0046] The side limiting posts 9 on both sides can move relative to each other under the action of the above-mentioned threaded drive structure, thereby changing the distance between the two side limiting posts 9. By dynamically adjusting the distance between the side limiting posts 9, it can be used to clamp square profiles of different lengths. It can meet the left and right clamping work of profiles of different lengths within a certain length adjustment range, and has good length size applicability, thus improving the overall applicability of the fixture of this utility model.

[0047] Meanwhile, the two opposing side jaws 15 of this utility model can be dynamically adjusted in distance through the action of the second set of threaded drive structure. This allows the side jaws 15 of this utility model to meet the clamping requirements for different width dimensions under dynamic adjustment, and has a good width adjustment effect, meeting the width requirements of different square profiles.

[0048] In summary, this utility model, through the structural cooperation between the side limiting posts 9 on both sides and the four side grippers 15, enables the clamping mechanism of this utility model to have a better clamping and fixing effect, which can effectively improve the overall structural stability of the clamping and provide a stable clamping effect in actual use, reducing processing risks. At the same time, the clamping mechanism has dynamic dimensional adjustability, which can meet the size adjustment requirements of profiles of different lengths and widths within a certain size adjustment range. It can be used for clamping and fixing square profiles of different sizes. The overall structure has stronger applicability, higher clamping stability, and better practical use effect. Moreover, the overall structure is simple, and the manufacturing and maintenance costs are low, making it suitable for installation and use in dual-station profile processing centers.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
