DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4, a high-efficiency and fast clamping machine tool fixture includes a base 1, two mounting seats 2 arranged above the base 1, and a controller 18 fixedly installed on the left mounting seat 2. The two mounting seats 2 are rotatably installed with mounting cylinders 3 inside, and the opposite ends of the two mounting cylinders 3 are detachably installed with chucks 4. The left mounting seat 2 is fixedly installed on the upper surface of the base 1, and the base 1 is provided with an adjustment component for the displacement of the right mounting seat 2. The connection between the mounting cylinder 3 and the mounting seat 2 is a bearing connection.

The adjustment assembly includes a servo motor 19 fixedly mounted on the outside of the base 1, a lead screw 20 extending into the inside of the base 1 is fixedly mounted on the output shaft of the servo motor 19, and a moving block 21 fixed to the lower surface of the right mounting seat 2 is connected to the external thread of the lead screw 20. A fixing platform is welded on the right outer wall of the base 1, and the servo motor 19 is fixedly mounted on the upper surface of the fixing platform.

In addition, a slide groove communicating with the outside is provided inside the base 1, and two guide rods 22 symmetrically distributed are fixedly installed between the inner walls on the left and right sides of the slide groove, and both guide rods 22 penetrate the interior of the moving block 21. Through the installation of the guide rods 22, the moving block 21 can be linearly displaced left and right, thereby improving the adjustment of the right mounting seat 2. The lead screw 20 extends into the interior of the slide groove and is connected to the bearing on the left inner wall thereof.

It can be understood that by starting the servo motor 19, its output shaft drives the screw 20 to rotate, and the rotation of the screw 20 drives the moving block 21 to move left and right, thereby moving the right side mounting seat 2, and adjusting the distance between the two mounting seats 2, which is convenient for clamping and fixing workpieces of different lengths, and achieving high efficiency.

In this embodiment, the two chucks 4 are internally provided with a clamping mechanism for clamping the workpiece, and the clamping mechanism includes a swivel seat 5, a slide seat 6, a motor 7 and a clamp 8. A connecting arm 11 is rotatably installed between the swivel seat 5 and the slide seat 6. The clamp 8 is detachably installed on the side of the slide seat 6 close to the swivel seat 5. A first transmission gear 9 is fixedly installed on the output shaft of the motor 7, and a first driven gear 10 meshing with the first transmission gear 9 is fixedly installed on the outside of the swivel seat 5.

The chuck 4 and the rotating seat 5 are both provided with through holes 13, the rotating seat 5 is located in the middle of the chuck 4, and the rotating seat 5 is connected to the internal bearing of the chuck 4. A slider 12 is fixedly mounted on the lower surface of the rotating seat 5, and a sliding opening 14 is provided inside the chuck 4, and the slider 12 is slidably connected to the sliding opening 14. The fixture 8 and the sliding seat 6 are fixed by bolts, and the fixture 8 can be replaced according to the needs of the workpiece.

It should be noted that the number of slides 6, clamps 8 and connecting arms 11 in the clamping mechanism are all four, and the four slides 6 are equidistantly distributed above the chuck 4. The motor 7 is fixedly installed inside the chuck 4, and a battery module electrically connected to the motor 7 is installed inside the chuck 4. The chuck 4 is detachably installed with an inspection plate. The interior of the rotating seat 5 is hollow.

In addition, the outer shape of the connecting arm 11 has a certain curvature, which facilitates the swivel seat to rotate better and drive the slide seat 6 to move.

In this embodiment, a turning mechanism for turning the workpiece is arranged above the base 1; the turning mechanism comprises a stepper motor 15 fixedly mounted on the upper surface of the base 1, a second driven gear 16 fixedly mounted on the outer surface of the left mounting cylinder 3, and a second transmission gear 17 fixedly mounted on the output shaft of the stepper motor 15, and the second transmission gear 17 is meshed with the second driven gear 16. The output shaft of the stepper motor 15 is connected to the outer bearing of the left mounting seat 2.

When this embodiment is in use, the stepper motor 15 drives the second transmission gear 17 to rotate, and the second transmission gear 17 rotates and engages with the second driven gear 16 to drive the left mounting cylinder 3 to rotate. Since both mounting cylinders 3 are rotationally connected to the mounting seat 2, the workpiece is flipped.

The working principle of the above embodiment is:

The motor 7 is started by operating the controller 18, so that its output shaft drives the first transmission gear 9 to rotate, and the first transmission gear 9 rotates and meshes with the first driven gear 10 to drive the swivel seat 5 to rotate. Since the swivel seat 5 and the slide seat 6 are rotatably connected with a connecting arm 11, when the swivel seat 5 rotates, the four slide seats 5 are driven to move and approach the through hole 13 through the four connecting arms 11, thereby clamping the workpiece. When the workpiece needs to be flipped, the stepper motor 15 is started to drive the second transmission gear 17 to rotate, and the second transmission gear 17 rotates and meshes with the second driven gear 16 to drive the left mounting cylinder 3 to rotate. Since the two mounting cylinders 3 are rotatably connected to the mounting seat 2, the flipping of the workpiece is realized.

The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
