[0024] like Figure 1 As shown, the utility model proposes: a high-precision quick-change device for a pneumatic pallet, comprising a base, a pallet, a conical sleeve, a conical flange, a cleaning air valve, a clamping air valve, an elastic part, an assembly part and a steel ball;

[0025] The base and the tapered flange are assembled and clearance-matched, and both the base and the tapered flange are "convex" shaped;

[0026] The tray is assembled on the tapered flange;

[0027] The base is provided with an annular clamping air groove, and the clamping air groove runs through the top surface of the base;

[0028] A plurality of elastic members are arranged in the clamping air groove, and are in contact and connection with the conical flange;

[0029] The outer wall of the conical flange protrusion is provided with a plurality of slidable steel balls, and the steel balls are in contact and connected with the outer surface of the base and the tray;

[0030] The conical flange is movably connected with a conical sleeve, and the conical sleeve is plug-fitted with the elastic member through an assembly part;

[0031] The top surface of the conical flange connected to the tray is an inclined surface, and the inclined direction of the inclined surface is inclined downward toward the outer wall of the conical flange;

[0032] The conical flange is equipped with a cleaning air valve and a clamping air valve;

[0033] The conical flange and the base are provided with interconnected clean air passages; one end of the clean air passage is connected to the clean air valve, and the other end of the clean air passage is in a "Y" shape and passes through the top of the base;

[0034] The conical flange is provided with a clamping air channel which is interconnected with the clamping air groove, and the clamping air channel is connected with the clamping air valve.

[0035] Wherein, the width of the top end of the conical sleeve is smaller than the width of the bottom end of the conical sleeve.

[0036] Among them, a rubber pad is provided on the surface of the conical flange, which is located above the conical sleeve to prevent foreign matter from invading from the outside.

[0037] Among them, a sealing ring for dust prevention is provided on the surface of the base, which is located between the steel ball and the "Y"-shaped port of the clean air duct to prevent foreign matter from invading from the outside.

[0038] Working principle:

[0039] The working principle of the high-precision quick-change device for pneumatic pallets integrates multiple steps such as cleaning, pallet assembly, clamping positioning and pallet seating confirmation. Before the pallet is assembled, the clean air valve is used to inflate the clean air channel, and the gas is ejected from the "Y"-shaped port at the top of the base to jet clean the contact surface between the pallet and the conical flange to remove possible foreign matter and coolant. At the same time, the inclined surface design of the conical flange helps foreign matter and coolant flow down the inclined surface, further preventing foreign matter from invading from the outside.

[0040] When the pallet is moved in and contacts the top of the conical flange and the base, the cleaning air valve is inflated again to form a small gap between the pallet and the conical flange, and jet cleaning is performed at the same time to ensure that there is no foreign matter or coolant residue on the contact surface between the pallet and the conical flange. This design can also prevent damage to the pallet caused by bumps during assembly and ensure high-precision positioning.

[0041] After cleaning is completed, close the cleaning air valve and open the clamping air valve. The air pressure enters the clamping air groove through the clamping air channel, pushing the elastic parts and the assembly parts to make the tapered sleeve rise. The rise of the tapered sleeve makes the pallet and the tapered flange form a closer contact. At the same time, because the steel balls on the outer wall of the tapered flange are in contact with the outer surface of the base and the pallet, the steel balls will generate downward pressure, further realizing the effective clamping and high-precision positioning of the pallet.

[0042] In addition, the design that the width of the top of the conical sleeve is smaller than the width of the bottom ensures that the conical sleeve can smoothly contact and apply pressure to the pallet when it rises. The rubber pad on the surface of the conical flange and the sealing ring on the surface of the base respectively play the role of preventing foreign matter from intruding and dust, further ensuring the stability and service life of the device. The entire device realizes efficient, precise and stable quick change of pallets through pneumatic control.

[0043] As an optional function, an air blow port can be provided on the inclined surface of the conical flange for use with an air inspection device. When the pallet is properly seated, the air blown out of the air blow port will be blocked by the pallet, and the air inspection device confirms whether the pallet is properly seated by detecting changes in the air flow.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should be aware that the technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
