Description

Technical Field

[0001] This utility model relates to the field of zero-point positioning fixture technology, and in particular to a zero-point positioning fixture with a quick change function. Background Technology

[0002] A zero-point positioning system is a unique positioning and locking device that keeps the zero point constant while moving a workpiece from one station to another, from one process to another, or from one machine tool to another. This saves auxiliary time spent re-aligning the zero point, ensures continuous operation, and improves work efficiency.

[0003] In existing technologies, multiple zero-point positioning fixtures are usually fixed to the same base plate with bolts. After installation, it is cumbersome to adjust the distance between the zero-point positioning fixtures. When positioning and clamping objects of different sizes, the zero-point positioning fixtures need to be disassembled and the installation position readjusted, which is inconvenient and reduces the practicality of the fixture. Therefore, this utility model proposes a zero-point positioning fixture with quick change function to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a zero-point positioning fixture with a quick-change function, which solves the problem that the existing technology is cumbersome in adjusting the distance between zero-point positioning fixtures, making it inconvenient to disassemble the zero-point positioning fixtures when positioning and clamping objects of different sizes, thus reducing the practicality of the fixture in use.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a zero-point positioning fixture with quick change function, including a mounting frame, a mounting base is installed at the top of the mounting frame, a zero-point positioning fixture body is installed above the mounting base, a guide groove is opened inside the mounting frame, a guide block is arranged inside the guide groove, the top of the guide block is connected to the bottom of the mounting base, and an adjustment mechanism is arranged on both sides inside the mounting frame.

[0006] The adjustment mechanism includes a connecting rod, a mounting cavity, a servo motor, a first bevel gear, a second bevel gear, a threaded rod, a threaded sleeve, a movable cavity, and a limiting structure. The connecting rod is installed between two guide blocks. The mounting cavity is installed on both sides inside the mounting frame. A servo motor is installed on one side of the top of the mounting cavity. A first bevel gear is installed on the upper side of one side inside the mounting cavity. The output end of the servo motor is connected to one end of the first bevel gear. A second bevel gear meshes with one side of the first bevel gear. A threaded rod is installed on one end of the second bevel gear. A threaded sleeve is provided on the outer wall of the threaded rod. A movable cavity is fixedly installed on the outer wall of the threaded sleeve. One end of the movable cavity is connected to one side of the connecting rod.

[0007] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is opened inside the mounting cavity, and a limiting block is provided inside the limiting groove. One end of the limiting block is connected to the outside of the movable cavity.

[0008] A further improvement is that two limiting grooves are formed inside the mounting cavity, and the two limiting grooves are symmetrically distributed about the central axis of the mounting cavity.

[0009] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0010] A further improvement is that the mounting bracket has a fixing groove inside, and the connecting rod slides inside the fixing groove.

[0011] A further improvement is that two guide grooves are provided inside the mounting frame, and the two guide grooves are symmetrically distributed between each other.

[0012] The beneficial effects of this utility model are as follows: By providing adjustment mechanisms on both sides inside the mounting frame, and utilizing the mutual cooperation between the connecting rod, mounting cavity, servo motor, first bevel gear, second bevel gear, threaded rod, threaded sleeve, movable cavity, limiting groove, and limiting block of the adjustment mechanism, the positions of the two sets of mounting seats and the zero-point positioning fixture body can be adjusted separately. This allows the fixture to conveniently adjust the distance between the mounting seat and the zero-point positioning fixture body during use, thereby greatly improving the practicality of the fixture. By providing guide grooves, guide blocks, and fixing grooves, and utilizing their mutual cooperation, the mounting seat and the zero-point positioning fixture body can be limited during movement, making the mounting seat and the zero-point positioning fixture body more stable during movement.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a zero-point positioning fixture with a quick-change function, including a mounting frame 1, a mounting base 2 mounted on the top of the mounting frame 1, a zero-point positioning fixture body 3 mounted above the mounting base 2, a guide groove 4 opened inside the mounting frame 1, a guide block 5 arranged inside the guide groove 4, the top of the guide block 5 connected to the bottom of the mounting base 2, and adjustment mechanisms arranged on both sides inside the mounting frame 1.

[0020] The adjustment mechanism includes a connecting rod 7, a mounting cavity 8, a servo motor 9, a first bevel gear 10, a second bevel gear 11, a threaded rod 12, a threaded sleeve 13, a movable cavity 14, and a limiting structure. The connecting rod 7 is installed between two guide blocks 5. The mounting cavity 8 is installed on both sides inside the mounting frame 1. The servo motor 9 is installed on one side of the top of the mounting cavity 8. The first bevel gear 10 is installed on the upper side of one side inside the mounting cavity 8. The output end of the servo motor 9 is connected to one end of the first bevel gear 10. The second bevel gear 11 meshes with one side of the first bevel gear 10. The threaded rod 12 is installed on one end of the second bevel gear 11. The outer wall of the threaded rod 12 is provided with a threaded sleeve 13. The outer wall of the threaded sleeve 13 is fixedly installed with a movable cavity 14. One end of the movable cavity 14 is connected to the connecting rod 7. Connected to one side, when in use, the servo motor 9 is started to drive the first bevel gear 10 to rotate. Since the first bevel gear 10 and the second bevel gear 11 mesh with each other, the second bevel gear 11 drives the threaded rod 12 to rotate, thus driving the threaded sleeve 13 to move. Then, under the limitation of the limiting groove 15 and the limiting block 16, the threaded sleeve 13 drives the movable cavity 14 to move. Then, under the limitation of the guide groove 4, the guide block 5 and the fixed groove 6, the movable cavity 14 drives the connecting rod 7 to move. Thus, the guide block 5 drives the mounting base 2 and the zero-point positioning fixture body 3 to move, adjusting the mounting base 2 and the zero-point positioning fixture body 3 to an appropriate position. This allows the fixture to be conveniently adjusted in use, thereby greatly improving the practicality of the fixture.

[0021] The limiting structure includes a limiting groove 15 and a limiting block 16. The limiting groove 15 is formed inside the mounting cavity 8, and the limiting block 16 is provided inside the limiting groove 15. One end of the limiting block 16 is connected to the outside of the movable cavity 14. There are two limiting grooves 15 inside the mounting cavity 8, and the two limiting grooves 15 are symmetrically distributed about the central axis of the mounting cavity 8. The cross-section of the limiting groove 15 is larger than the cross-section of the limiting block 16. The limiting groove 15 and the limiting block 16 form a sliding structure. In use, the mutual cooperation between the limiting groove 15 and the limiting block 16 can limit the movement of the movable cavity 14, making the movable cavity 14 more stable when moving.

[0022] The mounting bracket 1 has a fixing groove 6 inside, and the connecting rod 7 slides inside the fixing groove 6. In use, the fixing groove 6 can guide the connecting rod 7 when it moves, making the mounting base 2 more stable when it moves.

[0023] Two guide grooves 4 are provided inside the mounting frame 1. The two guide grooves 4 are symmetrically distributed between each other. The guide grooves 4 can guide the guide block 5 when it moves, so that the mounting base 2 is more stable when it moves.

[0024] Working principle: The operator starts the servo motor 9 to drive the first bevel gear 10 to rotate. Since the first bevel gear 10 and the second bevel gear 11 mesh with each other, the second bevel gear 11 drives the threaded rod 12 to rotate, which in turn drives the threaded sleeve 13 to move. Under the limitation of the limiting groove 15 and the limiting block 16, the threaded sleeve 13 drives the movable cavity 14 to move. Under the limitation of the guide groove 4, the guide block 5 and the fixing groove 6, the movable cavity 14 drives the connecting rod 7 to move. Therefore, the guide block 5 drives the mounting base 2 and the zero-point positioning fixture body 3 to move. The mounting base 2 and the zero-point positioning fixture body 3 are adjusted to the appropriate position. Finally, the four pull studs are inserted into the insertion holes inside the zero-point positioning fixture body 3. The pull studs are locked by the zero-point positioning fixture body 3, thus fixing the position of the external pallet.
