[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: a fixture for fastening processing in a gantry-type machining center, comprising a base 1, a gantry 2 fixedly connected to the top of the base 1, a processing structure can be installed on the top of the gantry 2, and after cooperating with the fixture, the workpiece can be processed. A mounting seat 3 is fixedly connected to the upper part of the base 1, and a gear disc 4 is rotatably connected to the top of the mounting seat 3. The gear disc 4 can be used to drive the workpiece to rotate. An adjustment component is fixedly connected to the outside of the gantry 2 for adjusting the angle of the gear disc 4. The adjustment component includes a motor 20. The motor 20 is fixedly connected to the outside of the gantry 2. The output end of the motor 20 is fixedly connected to a gear 21. The gear 21 and the gear disc 4 are meshed with each other. The driving motor 20 works to drive the gear 21 to rotate, thereby rotating the gear disc 4, and adjusting the orientation of the workpiece above the gear disc 4.

[0033] Reference Figure 1-Figure 3 The gear disc 4 is internally slidably connected to a plurality of movable seats 6. The top of the movable seat 6 is fixedly connected to an electric push rod 12. The top output end of the electric push rod 12 is fixedly connected to a connecting plate 13. The top of the connecting plate 13 is fixedly connected to an electric push rod 2 14. The output end of the electric push rod 2 14 is fixedly connected to a chuck 15. Driving the electric push rod 12 can drive the connecting plate 13 to move up and down, thereby adjusting the vertical height of the chuck 15. Driving the electric push rod 12 alone can change the position of a single chuck 15. The position of the entire workpiece can also be adjusted by driving the electric push rod 12 synchronously. The chuck 15 is then pushed out by the electric push rod 2 14, thereby achieving clamping and tightening of workpieces of different sizes. The outside of the electric push rod 12 is fixedly connected to a telescopic rod 16. The top of the telescopic rod 16 is fixedly connected to the bottom of the connecting plate 13. The telescopic rod 16 is used to position the electric push rod 12, thereby improving the stability of the chuck 15 when it moves up and down.

[0034] Reference Figure 2-Figure 4The middle of the toothed disc 4 is fixedly connected to a mounting block 5, and a through-hole 22 is formed in the middle of the mounting block 5. The outer side of the movable seat 6 is fixedly connected to a housing 9, and a plunger 10 is slidably connected to the middle of the housing 9. A spring 11 is sleeved on the outer periphery of the plunger 10, and the plunger 10 and the through-hole 22 are engaged. Before clamping and tightening the workpiece, the plunger 10 can be disengaged from the slot 8 and the through-hole 22 to adjust the position of the movable seat 6. The specific operation is to lift the plunger 10 upward to disengage the plunger 10 from the slot 8 and the through-hole 22, and move the movable seat 6 along the track 19. After the movable seat 6 is adjusted to the appropriate position, the plunger 10 is released and re-inserted from the middle of the through-hole 22. In this way, the installation position of multiple chucks 15 can be adjusted to meet the clamping and tightening needs of workpieces of different shapes. A positioning ring is fixedly connected to the outer side of the plunger 10, and a spring 11 is fixedly connected to the top of the positioning ring. The positioning ring limits the position of the plunger 10 to ensure the stability of the movement of the plunger 10. The top of the insertion rod 10 is rotatably connected with a pull ring, and after adding the pull ring, the insertion rod 10 can be operated more conveniently;

[0035] Reference Figure 2-Figure 3 The outside of the movable seat 6 is fixedly connected to a fixed block 7, and a slot 8 is provided on the top of the fixed block 7. The insertion rod 10 is engaged with the slot 8. After the slot 8 is added, after the insertion rod 10 passes through the middle of the through hole 22, it will also be engaged with the slot 8, thereby further stabilizing the insertion rod 10. The bottom of the fixed block 7 and the movable seat 6 are both rotatably connected to roller 17, and a track 19 is fixed on the top of the gear disc 4. Roller 17 is set inside the track 19. The position of the movable seat 6 is limited by roller 17 and the track 19, so that the position adjustment of the movable seat 6 is smoother. The outside of the movable seat 6 is also rotatably connected to roller 2 18, and roller 2 18 fits against the inner wall of the gear disc 4. After adding roller 2 18, a new fulcrum is added to the outside of the movable seat 6 to further improve the stability of the movable seat 6 when moving.

[0036] Working principle: when in use, first place the workpiece between the multiple chucks 15, then drive the electric push rod 12 to drive the connecting plate 13 to move up and down, so as to adjust the up and down height of the chuck 15, and then push the chuck 15 out by the electric push rod 2 14, thereby achieving clamping and tightening of workpieces of different sizes. The multiple electric push rods 12 can be driven separately, so that the appropriate clamping point can be selected according to the shape of the workpiece, and the position of the workpiece can be adjusted as a whole by synchronously driving the electric push rod 12; secondly, after completing the clamping of the workpiece, the motor 20 can be driven to drive the gear 21 to rotate, so as to rotate the gear disc 4, so that the overall position of the multiple chucks 15 can be driven to adjust, so as to adjust the direction of the workpiece, thereby making it more convenient to process the workpiece. It should be noted that because the electric push rod 1 12 and the electric push rod 2 14 are externally connected to circuits, the rotation angle of the gear disc 4 will be limited;

[0037] Before clamping and tightening the workpiece, the insertion rod 10 can be lifted upward to disengage the insertion rod 10 from the slot 8 and the through hole 22. At this time, the movable seat 6 can be moved along the track 19. After the movable seat 6 is adjusted to a suitable position, the insertion rod 10 is released. Under the action of the spring 11, the insertion rod 10 can be re-inserted from the middle of the through hole 22 and clamped with the slot 8, thereby realizing the adjustment of the installation position of multiple chucks 15 to meet the clamping and tightening needs of workpieces of different shapes.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
