Description

Technical Field

[0001] The utility model relates to water drill grinding and polishing equipment, in particular to a clamp positioning and clamping mechanism of a water drill grinding and polishing machine. Background Art

[0002] The water drill grinding and polishing machine can perform grinding and polishing on water drill blanks. During operation, the water drill fixture drives the horizontal blank to flow to the grinding and polishing station, and then clamps the water drill through the positioning and clamping mechanism, and then drives the water drill fixture close to the grinding and polishing wheel to perform the water drill grinding and polishing. At present, the positioning and clamping mechanism on the market is to set two cylinders to drive the corresponding lower claws to move, and then lift the water drill fixture upward and cooperate with the upper baffle to achieve the positioning and clamping of the water drill fixture. The defects of this structure are: due to the setting of two cylinders, the overall gas consumption of the equipment is large, and energy-saving production cannot be achieved; in addition, the synchronization of the two cylinders cannot be guaranteed, resulting in the inability to ensure that the water drill fixture is lifted steadily during the lifting process, and during long-term use, the moving stroke of the cylinder may have a certain deviation, resulting in the water drill fixture being unable to remain horizontal after being lifted, which will affect the subsequent water drill grinding and polishing. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a clamp positioning and clamping mechanism for a water drill grinding and polishing machine for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] The fixture positioning and clamping mechanism of a water drill grinding and polishing machine includes a mounting seat, characterized in that: a single clamping cylinder is arranged on the top of the mounting seat, the piston rod of the clamping cylinder is connected to the lifting block, one end of the lifting block is arranged with a first connecting shaft, and the other end is arranged with a second connecting shaft, the first connecting shaft passes through the first strip groove at one end of the first swing arm, the second connecting shaft passes through the second strip groove at one end of the second swing arm, the first swing arm is hinged to the first guide seat on the mounting seat, the other end of the first swing arm is hinged to the first transmission shaft, the first transmission shaft passes through the first guide groove on the mounting seat and is connected to the first clamp, the second swing arm is hinged to the second guide seat on the mounting seat, the other end of the second swing arm is hinged to the second transmission shaft, the second transmission shaft passes through the second guide groove on the mounting seat and is connected to the second clamp.

[0006] The mounting seat is arranged on a sliding frame, and the sliding frame is movably arranged on a base and connected with a sliding driving component.

[0007] The sliding frame is provided with a connecting block, the connecting block is detachably provided with a guide bar, the guide bar is provided with a slide groove corresponding to the shape of the bottom of the water drill clamp, and the first clamping jaw and the second clamping jaw are both arranged between the guide bars.

[0008] The first connecting shaft is a first screw rod screwed on the lifting block, and the second connecting shaft is a second screw rod screwed on the lifting block.

[0009] The fixture positioning and clamping mechanism of the water drill grinding and polishing machine of the above technical solution only needs to set a single cylinder to drive the movement of the two jaws, which effectively reduces the gas consumption of the equipment and realizes energy-saving production; at the same time, the single cylinder transmits the movement of the jaws through a mechanical transmission structure coordinated by a transmission arm and a transmission shaft, which can ensure the synchronization of the movement of the two jaws, improve the stability of the water drill fixture lifting, and ensure that the water drill fixture remains horizontal after being lifted into place, thereby ensuring the quality of subsequent water drill grinding and polishing on the water drill fixture.

[0016] As shown in the figure, the fixture positioning and clamping mechanism of the water drill grinding and polishing machine disclosed by the utility model includes a mounting seat 8, a single clamping cylinder 12 is arranged on the top of the mounting seat 8, the piston rod of the clamping cylinder 12 is connected to the lifting block 13, a first connecting shaft 22 is arranged at one end of the lifting block 13, and a second connecting shaft 23 is arranged at the other end. Specifically, the first connecting shaft 22 is a first screw rod screwed on the lifting block 13, and the second connecting shaft 23 is a second screw rod screwed on the lifting block 13, which is convenient for the installation of the first and second connecting shafts. The first connecting shaft 22 passes through the first strip groove 24 at one end of the first swing arm 11, and the second connecting shaft 23 passes through the second strip groove 25 at one end of the second swing arm 16. The first swing arm 11 is hinged to the first guide seat 10 on the mounting seat 8, and the other end of the first swing arm 11 is hinged to the first transmission shaft 9. The first transmission shaft 9 passes through the first guide groove on the mounting seat 8 and is connected to the first clamp 20. The second swing arm 16 is hinged to the second guide seat 14 on the mounting seat 8, and the other end of the second swing arm 16 is hinged to the second transmission shaft 15. The second transmission shaft 15 passes through the second guide groove on the mounting seat 8 and is connected to the second clamp 21. The first and second clamps can lift the water drill clamp 6 upward, and the mounting seat 8 is provided with an upper baffle 7 that abuts against the top of the water drill clamp 6. The mounting seat 8 is arranged on the sliding frame 4, and the sliding frame 4 is movably arranged on the base 5 and connected with the sliding drive assembly. Specifically, the sliding drive assembly includes a first motor 1, and the first motor 1 is connected with the driving screw 3 through a synchronous belt transmission group 2, and the driving screw 3 is screwed with the sliding frame 4. The corresponding sliding frame 4 is provided with a guide assembly. By controlling the first motor 1 to drive the driving screw 3 to rotate, the sliding frame 4 and the mounting seat 8 can be driven to move, so that the water drill fixture is close to or away from the grinding and polishing wheel. A connecting block 17 is arranged on the sliding frame 4, and a guide bar 18 is detachably arranged on the connecting block 17. A slide groove 19 corresponding to the bottom shape of the water drill fixture 6 is opened on the guide bar 18. The first clamping jaw 20 and the second clamping jaw 21 are both arranged between the guide bars 18. After the clamping jaw is lowered and separated from the water drill fixture 6, the water drill fixture 6 can be placed on the guide bar 18 and slide to realize the circulation of the water drill fixture.

[0017] The working principle of the utility model is: when the water drill clamp 6 is transferred to the processing station, the single clamping cylinder 12 drives the lifting block 13 to descend, and the movement of the lifting block 13 will simultaneously drive the first and second transmission arms to swing, thereby driving the first and second transmission shafts to move, driving the first and second clamping claws to rise and lift the water drill clamp 6 until it abuts against the upper baffle 7, thereby achieving the clamping and positioning of the water drill clamp.

[0018] The structure of the utility model sets a single cylinder to drive the movement of the two clamping jaws, effectively reducing the gas consumption of the equipment and realizing energy-saving production; at the same time, the single cylinder drives the movement of the clamping jaws through a mechanical transmission structure coordinated by a transmission arm and a transmission shaft, thereby ensuring the synchronization of the movement of the two clamping jaws, improving the stability of the lifting of the water drill clamp, and ensuring that the water drill clamp remains horizontal after being lifted into place, thereby ensuring the quality of subsequent water drill grinding and polishing on the water drill clamp.
