Description

Technical Field

[0001] This application relates to the technical field of grinding machine fixtures, and in particular to an angle adjustment structure for a tool grinding machine fixture. Background Art

[0002] "An angle adjustment structure for a tool grinding machine fixture" is disclosed in "CN219358896U", which includes a tool fixture body and a support frame. Both bottom sides of the tool fixture body are fixedly installed with support frames... A fixed ear is fixedly installed at the bottom of the side wall of the fixed seat. By setting an angle adjustment cylinder, a rotating wheel, and a dual-axis motor, the rotating wheel can be driven to rotate under the drive of the dual-axis motor. After the rotating wheel rotates, the up-and-down angle of the tool fixture body at the top can be changed, so that it is convenient for the fixture to cooperate with the processing head to change the up-and-down angle of the clamped tool, making the operation more flexible.

[0003] Regarding the above related technology, the inventor believes that when adjusting the up-and-down angle of the tool fixture body, the dual-axis motor is directly used to drive the tool fixture body to rotate. Due to the lack of a self-locking structure, when the processing head grinds the workpiece on the fixture, the force generated and the gravity of the fixture itself are both borne by the motor load. After long-term use, the motor failure rate is high, leading to easy occurrence of safety accidents. Therefore, an angle adjustment structure for a tool grinding machine fixture is proposed to solve the above problems.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0005] In order to solve the problem that due to the lack of a self-locking structure, when the processing head grinds the workpiece on the fixture, the force generated and the gravity of the fixture itself are both borne by the motor load. After long-term use, the motor failure rate is high, leading to easy occurrence of safety accidents, this application provides an angle adjustment structure for a tool grinding machine fixture.

[0006] The angle adjustment structure for a tool grinding machine fixture provided by this application adopts the following technical solutions:

[0007] An angle adjustment structure for a tool grinding machine fixture includes a fixed seat. The outer wall of the top of the fixed seat is rotationally connected with a rotating disk through a bearing ring. The outer wall of the top of the rotating disk is fixedly connected with a base. The outer wall of the top of the base is fixedly connected with a semi-circular seat. The semi-circular seat is movably installed with a movable seat through a fixing component on the outer wall of the top. The outer wall of the top of the movable seat is fixedly connected with a tool fixture body through a bracket. An angle adjustment mechanism is installed between the semi-circular seat and the movable seat.

[0008] The angle adjustment mechanism includes a worm gear fixedly connected to the outer wall of the middle section at the top of the semi-circular seat. A worm is rotatably connected to the outer wall of the middle section at the bottom of the movable seat through a shaft seat. The worm is engaged with the worm gear. A servo motor is fixedly installed on one outer wall of the movable seat, and the end of the output shaft of the servo motor is fixedly connected to one end of the worm.

[0009] Preferably, the fixing component includes threaded columns fixedly connected to the outer walls at the bottoms of both sides of the movable seat. Gaskets are movably connected to the outer walls of the threaded columns, and nuts are threadedly connected to the outer walls of the threaded columns below the gaskets.

[0010] Preferably, the fixing component further includes arc-shaped grooves formed in the outer walls at both sides of the top of the semi-circular seat. The two threaded columns are slidably connected to the inner walls of the two arc-shaped grooves, and both the gasket and the nut are located below the arc-shaped grooves.

[0011] Preferably, a stepper motor is fixedly installed on the inner wall at the bottom of the fixed seat, and the end of the output shaft of the stepper motor is fixedly connected to the outer wall in the middle at the bottom of the rotating disk.

[0012] Preferably, a plurality of fixing ears are fixedly connected to the outer wall near the bottom of the fixed seat, and the plurality of fixing ears are evenly distributed in a circumferential array at equal intervals on the outer wall of the fixed seat.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] Through the provided angle adjustment mechanism, the movable seat can be driven to rotate around the axis of the semi-circular seat, thereby changing the up and down angle of the top tool fixture body, and further adjusting the angle of the fixture for clamping the tool, which is convenient for cooperating with the processing head for processing. Compared with the prior art, the meshing transmission between the worm gear and the worm in the angle adjustment mechanism has self-locking property, so that when the tool fixture body adjusts the angle, it can be locked in real time, avoiding the force generated during the processing of the processing head and the gravity of the fixture itself from being directly borne by the motor load, reducing the failure rate of the motor, and ensuring the processing safety.

Detailed implementation manners

[0019] The following further elaborates on this application in conjunction with the Figures 1-3 accompanying drawings.

[0020] The embodiment of this application discloses an angle adjustment structure for a tool grinding machine fixture. Referring to Figures 1-3 , an angle adjustment structure for a tool grinding machine fixture includes a fixed seat 1. The outer wall of the top of the fixed seat 1 is rotatably connected to a rotating disk 3 through a bearing ring 2. The outer wall of the top of the rotating disk 3 is fixedly connected to a base 4. The outer wall of the top of the base 4 is fixedly connected to a semi-circular seat 5. The outer wall of the top of the semi-circular seat 5 is movably installed with a movable seat 6 through a fixing component. The outer wall of the top of the movable seat 6 is fixedly connected to a tool fixture body 8 through a bracket 7. An angle adjustment mechanism is installed between the semi-circular seat 5 and the movable seat 6;

[0021] The angle adjustment mechanism includes a worm gear 13 fixedly connected to the outer wall of the middle section of the top of the semi-circular seat 5. The outer wall of the middle section of the bottom of the movable seat 6 is rotatably connected to a worm 15 through a shaft seat 14. The worm 15 meshes with the worm gear 13. A servo motor 16 is fixedly installed on one outer wall of the movable seat 6. The end of the output shaft of the servo motor 16 is fixedly connected to one end of the worm 15.

[0022] The fixing component includes threaded columns 10 fixedly connected to the outer walls of the two sides of the bottom of the movable seat 6. The outer walls of the threaded columns 10 are movably connected to gaskets 11. The outer walls of the threaded columns 10 located below the gaskets 11 are threadedly connected to nuts 12.

[0023] The fixing component further includes arc grooves 9 opened on the outer walls of the two sides of the top of the semi-circular seat 5. The two threaded columns 10 are slidably connected to the inner walls of the two arc grooves 9. Both the gasket 11 and the nut 12 are located below the arc grooves 9.

[0024] A stepper motor 17 is fixedly installed on the inner wall of the bottom of the fixed seat 1. The end of the output shaft of the stepper motor 17 is fixedly connected to the outer wall of the middle of the bottom of the rotating disk 3.

[0025] A plurality of fixed ears 18 are fixedly connected to the outer wall of the fixed seat 1 near the bottom. The plurality of fixed ears 18 are evenly distributed in a circumferential array at equal intervals on the outer wall of the fixed seat 1. The fixed seat 1 can be fixedly installed by using screws through the fixed ears 18.

[0026] The implementation principle of the angle adjustment structure of a tool grinding machine fixture in an embodiment of the present application is as follows: When it is necessary to adjust the vertical angle of the tool fixture body 8, the servo motor 16 is started. The output shaft of the servo motor 16 drives the worm 15 to rotate. When the worm 15 rotates, it drives the worm gear 13 to rotate through meshing with the worm gear 13. Since the worm gear 13 is fixed on the semi-circular seat 5, at this time, the worm 15 rotates around the axis of the worm gear 13. At this time, the worm 15 drives the movable seat 6 to rotate, and the movable seat 6 rotates around the axis of the semi-circular seat 5. The movable seat 6 and the semi-circular seat 5 are connected and rotated through a fixing component. Specifically: When the movable seat 6 rotates, it will drive the threaded column 10 to slide on the inner wall of the arc-shaped groove 9, and the threaded column 10 is limited in the arc-shaped groove 9 through the gasket 11 and the nut 12. Therefore, the movable seat 6 is movably installed on the outer wall of the semi-circular seat 5. When the movable seat 6 rotates around the axis of the semi-circular seat 5, it drives the tool fixture body 8 to adjust the vertical angle through the bracket 7. When the horizontal position of the tool fixture body 8 needs to be adjusted, the stepping motor 17 is started. The output shaft of the stepping motor 17 drives the rotating disk 3 to rotate on the inner wall of the bearing ring 2, and then changes the horizontal position of the upper tool fixture body 8 through the rotating disk 3. In this way, the tool held can adjust the angle longitudinally and change the position horizontally, with flexible adjustment, facilitating the tool held to cooperate with the processing head for processing flexibly.
