Description

Technical Field

[0001] The utility model relates to the technical field of suction nozzles, and specifically relates to a quick-disassembly suction nozzle tooling. Background Art

[0002] In 3C non-standard equipment (such as mechatronic equipment, hydraulic transmission equipment, special machine tools, etc.), suction nozzles are often used to adsorb materials by negative pressure and then transplant and carry them. However, due to the different specifications of products, different specifications of suction nozzles need to be replaced according to the actual production requirements during the production process. In the prior art, the suction nozzles are often fixed to the corresponding components by screws, which results in a large amount of time being consumed to loosen and tighten the screws during the disassembly and replacement process, thus reducing the work efficiency. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a quick-disassembly suction nozzle tooling, which can quickly disassemble and replace the suction nozzle and improve the work efficiency.

[0004] The utility model adopts the following technical scheme: a quick-disassembly suction nozzle tooling, including a connection component and a suction nozzle component detachably assembled with the connection component. The connection component includes a connection seat, the connection seat is a hollow structure, an air inlet is opened on the connection seat to form an air cavity with the hollow part of the connection seat. A plurality of installation holes are circumferentially arranged on the outer wall of the connection seat, and ball bearings are press-fitted in the installation holes. An elastic reset sleeve is tightly sleeved on the outer wall of the connection seat corresponding to the position of the ball bearings. The suction nozzle component includes a hollow connecting rod, and the suction nozzle is embedded at the bottom of the connecting rod. One end of the connecting rod penetrates into the connection seat and is communicated with the air cavity. An annular flange is provided at the top end of the connecting rod, and the upper and lower end faces of the flange have tapers.

[0005] Further, the air inlet is connected to an air pipe, the connection seat is in a T shape, a groove is circumferentially arranged on the outer wall of the connection seat, and the elastic reset sleeve is tightly sleeved in the groove;

[0006] Further, the diameter of the installation hole is smaller than the diameter of the ball bearing, the inner side of the ball bearing extends into the air cavity, and the distance between the inner side wall point of the ball bearing and the inner wall of the connection seat is 1 mm to 1.5 mm;

[0007] Further, the connecting rod is in a cross shape, an installation groove is provided on the inner wall surface at the bottom of the connecting rod, and the suction nozzle is assembled in the installation groove;

[0008] Further, there are at least 2 installation holes, which are circumferentially arranged on the outer wall of the connection seat; the connecting rod and the connection seat are connected by a non-rotating positioning pin;

[0009] Further, a receiving groove is provided on the outer wall of the connecting rod below the flange to receive the ball bearings.

[0010] The beneficial effects of the present utility model are as follows: When the connection assembly and the nozzle assembly are assembled, the tapered flange gives an outward force to the ball bearings, causing the ball bearings to retract. Then, the nozzle assembly can be quickly connected to the connection assembly. When the nozzle assembly needs to be quickly disassembled, only a downward force needs to be applied to the connecting rod to make the ball bearings retract, so that the connecting rod and the connection seat can be conveniently and quickly separated, thereby realizing the quick disassembly and replacement of the nozzle, improving work efficiency, and having good economic use value.

[0016] As Figures 1 to 5 shown, a quick-release nozzle tooling of the present utility model includes a connection assembly and a nozzle assembly detachably assembled with the connection assembly. The connection assembly includes a connection seat 1. The connection seat 1 is a hollow structure. An air inlet 2 is provided on the connection seat 1 to form a negative pressure air cavity 3 with the hollow part of the connection seat 1. A plurality of mounting holes 4 are circumferentially arranged on the outer wall of the connection seat 1. Ball bearings 5 are press-fitted in the mounting holes 4. An elastic return sleeve 6 is tightly sleeved on the outer wall of the connection seat 1 corresponding to the position of the ball bearings 5, which is used to keep the ball bearings 5 in the mounting holes 4 without falling off, and at the same time applies an elastic force to the ball bearings 5 to make the inner sides of the ball bearings 5 protrude into the air cavity 3; The nozzle assembly includes a hollow connecting rod 7. A nozzle 8 is embedded at the bottom of the connecting rod 7. One end of the connecting rod 7 passes through the connection seat 1 and is communicated with the air cavity 3. An annular flange 9 is provided at the top end of the connecting rod 7. The upper end surface 10 and the lower end surface 11 of the flange 9 both have a taper.

[0017] The air inlet 2 is connected to a trachea 12. The connection seat 1 is in a T shape. A groove 13 is circumferentially provided on the outer wall of the connection seat 1. The elastic return sleeve 6 is tightly sleeved in the groove 13.

[0018] The diameter of the mounting hole 4 is smaller than the diameter of the ball 5. The inner side of the ball 5 extends into the air chamber 3, and the distance between the inner side wall point of the ball 5 and the inner wall of the connecting seat 1 is 1 mm. The connecting rod 7 is cross-shaped, and an installation groove 14 is provided on the inner wall surface of the bottom of the connecting rod 7. The suction nozzle 8 is assembled in the installation groove 14. There are 4 mounting holes 4, which are circumferentially arranged on the outer wall of the connecting seat 1. The connecting rod 7 and the connecting seat 1 are connected by a non-rotating positioning pin 15. A receiving groove 16 is provided on the outer wall of the connecting rod 7 below the flange 9 to receive the ball 5.

[0019] In the present utility model, both the connecting seat 1 and the connecting rod 7 are hollow structures, and the interior is connected to form a negative pressure adsorption circuit. When the suction nozzle assembly needs to be installed, the connecting rod 7 is inserted into the air chamber 3 of the connecting seat 1. The upper end surface 10 of the flange 9 (which is a tapered inclined surface) will give an outward force to the ball 5 to make the ball 5 retract. As the connecting rod 7 moves upward, the elastic reset sleeve 6 makes the ball 5 closely adhere to the lower end surface 11 of the flange 9 (which is still a tapered inclined surface). At this time, the ball 5 is located in the receiving groove 16, thereby restricting the connecting rod 7 from detaching from the connecting seat 1. The non-rotating positioning pin 15 can restrict the rotational movement between the connecting rod 7 and the connecting seat 1. At this time, the interior of the connecting seat 1 and the connecting rod 7 is connected to form a negative pressure adsorption circuit;

[0020] When the suction nozzle assembly is quickly disassembled, an artificial downward force is applied to the connecting rod 7. The lower end surface 11 of the flange 9 will give an outward force to the ball 5 to make the ball 5 retract, so that the connecting rod 7 and the connecting seat 1 are separated. After separation, the ball 5 is reset under the pressure of the elastic reset sleeve 6;

[0021] In summary, after suction nozzles 8 of different specifications are installed on the connecting rod 7, only by the above method can the connecting rod 7 be quickly assembled and replaced, that is, the suction nozzles 8 of different specifications can be quickly disassembled and replaced.
