[0005] Due to the uncertainty of the length or width of the workpiece, when the turntable at the top of the double-axis positioner clamps the workpiece through the fixture, since the distance between the mounting tables on both sides of the base cannot be adjusted, the rotation of workpieces with different lengths will be affected, resulting in a smaller applicable range of the double-axis positioner, and thus causing inconvenience. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a double-axis positioner applicable to different workpieces, enabling the body of the positioner to increase the spacing and improving the adaptability range of the device for clamping workpieces.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] like Figures 1 to 5As shown in the figure, a biaxial positioner applicable to different workpieces includes a base 1 connected to the biaxial machine body, two side mounting platforms 2 connected to the base 1, an L-shaped connecting plate 3 connected to the inner walls of the two side mounting platforms 2, and a rotating table 4 connected between the two L-shaped connecting plates 3. An installation groove is formed in the base 1. The bottom surfaces of the two side mounting platforms 2 are fixedly connected with T-shaped bases 5 that are slidably connected to the installation groove. A transmission component located in the installation groove is connected between the two T-shaped bases 5. The transmission component includes a gear 9. The gear 9 is located in the installation groove and is rotatably connected. Rack plates 11 are meshed and connected to both sides of the gear 9. The two rack plates 11 are arranged in a staggered manner. One ends of the two rack plates 11 are respectively fixedly connected to the outer walls of the two T-shaped bases 5, and the rack plates 11 are located in the installation groove and are slidably connected. A motor 10 is connected in the installation groove. A transmission belt is sleeved on the outer side of the output end of the motor 10, and the other end of the transmission belt is sleeved on the top of the gear 9. A sliding member is connected between the two L-shaped connecting plates 3.

[0026] As Figure 1 shown, the biaxial positioner applicable to different workpieces in the present utility model is similar in structure to the existing oil-water separator. For example, the oil-water separator disclosed in the patent with the publication number CN211283795U. The main improvement point of the present utility model is that the user can more conveniently clean the filter residue basket. As Figures 1 to 5 shown, when the biaxial positioner applicable to different workpieces in the present utility model is in use, when it is necessary to adjust the distance between the two side mounting platforms 2 of the biaxial positioner body, the motor 10 in the transmission component can be started. Here, the motor 10 should be a forward and reverse motor. The output end of the motor 10 rotates, driving the transmission belt to rotate, and then driving the top of the gear 9 to rotate, causing the gear 9 to rotate. When the gear 9 rotates, it will engage and drive with the rack plates 11 on both sides. The two rack plates 11 respectively move towards both ends of the base 1. The rack plates 11 are fixedly connected to the T-shaped bases 5, further pushing the T-shaped bases 5 to slide in the installation groove, and then causing the side mounting platforms 2 to move. During the process of the side mounting platforms 2 moving towards both sides, the two L-shaped connecting plates 3 are driven to move relatively on both sides of the rotating table 4. Thus, the adjustment of the distance between the two side mounting platforms 2 is completed;

[0027] Through the mutual cooperation of the motor 10, the gear 9, the rack plates 11, and the T-shaped bases 5, the distance between the two side mounting platforms 2 can be adjusted. When the distance between the two side mounting platforms 2 is increased, the workpiece on the rotating table 4 will not be blocked by the side mounting platforms 2 during the rotation process. Further, the biaxial positioner can be applicable to the rotation of workpieces with different lengths or widths, improving the applicable range of the biaxial positioner.

[0028] As Figure 3As shown, the sliding member includes two side plates 401, which are respectively fixedly connected to the outer wall of the driving housing at the lower end of the rotating table 4. There are moving grooves 301 formed in the two L-shaped connecting plates 3, and the side plates 401 are located in the moving grooves 301 and are slidably connected thereto.

[0029] Specifically, when the two side mounting platforms 2 are moving, the two L-shaped connecting plates 3 and the outer wall of the driving housing at the lower end of the rotating table 4 will slide relative to each other. The driving housing at the lower end of the rotating table 4 is located between the two L-shaped connecting plates 3, and the side plates 401 on both sides of the outer wall of the lower end of the rotating table 4 will slide with the moving grooves 301 in the L-shaped connecting plates 3. With this setting, when the side mounting platform 2 slides relatively, the rotating table 4 can still maintain its central position.

[0030] As Figure 5 shown, a plurality of groups of rollers 13 are fixedly connected to the bottom surface of the T-shaped base 5, and the plurality of groups of rollers 13 are slidably connected and movably connected to the inner wall of the installation groove.

[0031] Specifically, when the T-shaped base 5 slides in the installation groove, the outer wall of the roller 13 is slidably connected and rollingly connected to the bottom surface of the installation groove. With this setting, when the T-shaped base 5 slides, the sliding friction on its bottom surface is changed by the roller 13 into rolling friction, thereby making the movement of the T-shaped base 5 smoother.

[0032] As Figure 4 and Figure 6 shown, mounting plates 14 are fixedly connected to both sides of the outer wall of the T-shaped base 5, the bottom surface of the mounting plates 14 is slidably connected to the top surface of the base 1, and two groups of symmetrically arranged limiting grooves 101 are formed on the upper surface of the base 1. A T-shaped slider 12 connected to the mounting plate 14 is slidably connected in the limiting grooves 101.

[0033] Specifically, in order to ensure that the sliding of the T-shaped base 5 on the installation groove is more stable, when the T-shaped base 5 slides, it will drive the mounting plate 14 to slide, thereby making the T-shaped slider 12 slide with the limiting groove 101.

[0034] As Figure 6 shown, a threaded rod 15 is connected to the top surface of the T-shaped slider 12, and the bottom end of the threaded rod 15 passes through the mounting plate 14 and is threadedly connected to the T-shaped slider 12.

[0035] Specifically, by passing the threaded rod 15 through the mounting plate 14 and threadedly connecting it to the T-shaped slider 12, the T-shaped base 5 can be disassembled from the base 1, which is convenient for installation and subsequent maintenance and replacement.

[0036] As Figure 1 and Figure 2 shown, a cover plate 8 is connected to the top surface of the base 1 where the top surface of the motor 10 is located. The setting of the cover plate 8 facilitates the installation and maintenance of the motor 10 and the gear 9.

[0037] As Figure 1 , Figure 2 and Figure 7 shown, an end of the T-shaped base 5 is fixedly connected to a bellows cover 7, and the other end of the bellows cover 7 is connected to the base 1. In order to prevent welding slag from falling into the installation groove during the welding process, the bellows cover 7 can be used to block the exposed installation groove, playing a certain protective role.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
