DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figures 1-4 , an auxiliary fixed tool for a processing lathe, comprising:

[0025] A fixed plate 1, with a placement ring 11 provided above the fixed plate 1;

[0026] Hydraulic mechanism 2, the hydraulic mechanism 2 is used to clamp and fix parts, including a liquid storage ring 21 installed above the fixed plate 1, and a number of liquid storage sleeves 22 are provided on the liquid storage ring 21, each liquid storage sleeve 22 is sealed and slidably installed with a push rod 23, and each liquid storage sleeve 22 is connected to the interior of the liquid storage ring 21 through a connecting pipe 24, a liquid storage cylinder 25 is provided on the fixed plate 1, and a rotating sleeve 26 is rotatably installed below the liquid storage cylinder 25, and a liquid infusion tube 27 is provided above the liquid storage ring 21, and the liquid storage cylinder 25 is connected to the interior of the liquid storage ring 21 through the rotating sleeve 26 and the liquid infusion tube 27, and a cylinder 28 is provided above the liquid storage cylinder 25, and the output shaft of the cylinder 28 extends into the liquid storage cylinder 25, and a first piston block 29 is fixedly installed.

[0027] Among them, several push rods 23 are extended into the placement ring 11, so when the hydraulic oil pushes the push rods 23 to move in the liquid storage sleeve 22, they can approach the parts and abut against the peripheral side walls of the parts to clamp and fix the parts.

[0028] The rotating sleeve 26 is sealed and rotatably connected to the outer wall of the infusion tube 27 to ensure that the hydraulic oil does not overflow during the transportation process, while allowing the rotating sleeve 26 to rotate to ensure the subsequent operation of the adsorption mechanism 3.

[0029] In view of the problem that the parts in the prior art are diverse and have irregular designs, it is difficult to clamp and fix parts of various styles, and the scope of application is very limited, the utility model sets a hydraulic mechanism 2. During processing, the cylinder 28 drives the first piston block 29 to move downward in the liquid storage cylinder 25, and the hydraulic oil in the liquid storage cylinder 25 is transported to the liquid storage ring 21, and further the hydraulic oil is transported to the liquid storage sleeve 22 through the connecting pipe 24, so that the push rod 23 is abutted against the part, and in the subsequent hydraulic oil delivery process, several push rods 23 are successively abutted against the part, so that the several push rods 23 fit the irregular design of the part, and the part is clamped and fixed, with a wider scope of application. According to the characteristic that hydraulic oil is difficult to compress, the push rod 23 is not easy to loosen after abutting against the peripheral wall of the part, thereby ensuring the fixing effect of the part.

[0030] The adsorption mechanism 3 is used to improve the fixing effect of the parts, including a fixed cylinder 31 installed above the fixed plate 1, a negative pressure chamber 32 is provided in the fixed cylinder 31, a suction sleeve 33 is provided on the fixed plate 1, the suction sleeve 33 is communicated with the inside of the negative pressure chamber 32 through an air inlet pipe 34, and the suction sleeve 33 is communicated with the outside through an exhaust pipe 35, a reciprocating screw 36 is rotatably installed in the suction sleeve 33, a second piston block 37 is threadedly connected to the reciprocating screw 36, the second piston block 37 is sealingly and slidably installed on the inner wall of the suction sleeve 33, a transmission rod 38 is rotatably installed in the liquid storage ring 21, the part of the transmission rod 38 extending into the infusion tube 27 is provided with axial flow fan blades 39, the transmission rod 38 is fixedly connected to the rotating sleeve 26, a gear ring 310 is provided on the outer wall of the rotating sleeve 26, a gear 311 is provided on the top of the reciprocating screw 36, and the gear ring 310 and the gear 311 are meshed with each other.

[0031] The placement ring 11 is installed above the fixing tube 31 , so in actual use, the parts can be placed on the fixing tube 31 so as to be located inside the placement ring 11 .

[0032] Among them, both the air inlet pipe 34 and the exhaust pipe 35 are provided with a one-way valve. Through the setting of the one-way valve, when the second piston block 37 moves upward in the suction sleeve 33, the air in the negative pressure chamber 32 can only be sucked into the suction sleeve 33 through the air inlet pipe 34, and when the second piston block 37 moves downward in the suction sleeve 33, the air in the suction sleeve 33 can only be discharged to the outside through the exhaust pipe 35, avoiding air backflow, thereby ensuring that the air pressure in the negative pressure chamber 32 is continuously reduced, ensuring the adsorption effect on the parts.

[0033] In view of the problem that parts can only be fixed by clamping in the prior art, the fixing method is relatively simple and the fixing effect is poor, the utility model sets an adsorption mechanism 3. During the delivery of hydraulic oil, the axial flow fan blades 39 are driven to rotate by the flow of hydraulic oil, and the rotating sleeve 26 is further driven to rotate by the transmission rod 38, so that the gear ring 310 on the outer wall of the rotating sleeve 26 rotates, and the reciprocating screw rod 36 is driven to rotate under the action of the gear 311, so that the second piston block 37 performs reciprocating vertical displacement, and reciprocally sucks out the air in the negative pressure chamber 32 into the suction sleeve 33 and discharges it to the outside, so that the air pressure in the negative pressure chamber 32 is reduced, so that the parts placed above the fixing cylinder 31 can be tightly adsorbed on the fixing cylinder 31 under negative pressure, thereby improving the fixing effect of the parts.

[0034] The functional principle of this utility model can be explained through the following operation modes:

[0035] During processing, the cylinder 28 drives the first piston block 29 to move downward in the liquid reservoir 25, and the hydraulic oil in the liquid reservoir 25 is delivered to the liquid reservoir ring 21. The hydraulic oil is further delivered to the liquid reservoir sleeve 22 through the connecting pipe 24, and the push rod 23 is abutted against the part. In the subsequent hydraulic oil delivery process, several push rods 23 are sequentially abutted against the part, so that the several push rods 23 fit the irregular design of the part.

[0036] During the hydraulic oil delivery process, the flow of hydraulic oil drives the axial flow fan blades 39 to rotate, and further drives the rotating sleeve 26 to rotate through the transmission rod 38, so that the gear ring 310 rotates, and under the action of the gear 311, drives the reciprocating screw rod 36 to rotate, so that the second piston block 37 performs reciprocating vertical displacement, reciprocatingly sucking out the air in the negative pressure chamber 32 into the suction sleeve 33 and exhausting it to the outside, so that the air pressure in the negative pressure chamber 32 is reduced, so that the parts placed above the fixed cylinder 31 can be tightly adsorbed on the fixed cylinder 31 under negative pressure.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
