Abstract
The utility model provides a rubber cutting machine, which is provided with a mainshaft (5), a tail tip seat (13), a knife frame (9), and a workpiece core shaft (1) which is arranged between a mainshaft finial (20) and the tail tip seat. The utility model is characterized in that the central part of the workpiece core shaft is a hard core shaft (23); the exterior of the hard core shaft is sleeved with a sealed cylindrical rubber gasbag (26); the exterior of the rubber gasbag (26) is sleeved with a rubber casing (27); an internal chamber of the rubber gasbag is communicated with an air tube (4) by a high-speed joint (16); the air tube is communicated with air source. The utility model has the advantages of convenient disassembling workpieces, and being able to process workpieces with a plurality of diameters with one workpiece core shaft.
Description
Affiliated technical field
The utility model belongs to a kind of rubber cutting machine that is used to cut rubber washer.
Background technology
The rubber cutting machine primary structure of existing processing rubber packing ring is: a main shaft that is in transmission connection with motor is set on workbench, the nylon mandrel is housed between spindle top and tail tip seat, the processing knife rest is connected with axial screw drive, knife bar on the knife rest with can drive it and radially advance, the cam link mechanism of withdrawing is in transmission connection, screw rod with can drive its toggle that intermittently rotates and be in transmission connection, during the processing rubber packing ring, the rubber tube blank is enclosed within on the nylon mandrel, the nylon mandrel rotates under driven by motor, blade on the knife rest advances cutter No. one time to the rubber blank, can cut next rubber washer, behind the withdrawing, screw rod rotates under toggle drives, and tool axis is marched forward, and then radially feed, downcut next rubber washer, so circulation is unloaded the nylon mandrel from tail tip seat at last, and the rubber washer that processes is taken off.The weak point of this device be the workpiece gum sleeve be resilient tight fit be enclosed within on the nylon mandrel, material loading or discharging operation all compare difficult, and nylon mandrel can only be processed a kind of workpiece of diameter.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of workpiece loading and unloading convenience and can process the rubber cutting machine of multiple diameter workpiece with a workpiece mandrel.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with the main shaft (5) that is in transmission connection with motor (2) on workbench, workpiece mandrel (1) is contained between spindle top (20) and the tail tip seat (13), also be provided with the knife rest (9) of the cutter of radially advancing and retreat on the workbench, knife rest is in transmission connection with the screw rod (6) that can drive its stepping at intermittence, it is characterized in that: described workpiece mandrel (1) centre is hard mandrel (23), the Packed cylindrical shape rubber pneumatic bag of hard cores outer shaft sleeve (26), rubber pneumatic bag is with rubber sheath (27) outward, the rubber pneumatic bag inner chamber is communicated with tracheae (4) by high-speed joint (16), and tracheae is communicated with source of the gas.
Operation principle of the present utility model is: during the dress workpiece, make the decompression of rubber pneumatic bag inner chamber by tracheae, the rubber tube blank is enclosed within on the workpiece mandrel, withstand the workpiece mandrel other end with tail tip seat, pressurize to airbag aeration again, the stretching rubber tube, knife rest radially during feed, downcuts rubber ring, and screw rod drives tool axis to stepping behind the withdrawing, and then feed, until the rubber blank has all been cut, when unloading workpiece, make the rubber pneumatic bag decompression earlier, unload the workpiece that processes again, the sheath breakage that rubber pneumatic bag is outer can change at any time.
The utility model workpiece loading and unloading is convenient, and owing to the diameter of rubber pneumatic bag can elasticity change, so a workpiece mandrel can be processed the blank of multiple diameter.

Specific embodiments
This routine workpiece mandrel 1 structure is: rubber pneumatic bag 26 is enclosed within outside the hard mandrel 23 of metal, air bag two annular end faces and hard mandrel both ends of the surface are tightly connected, main shaft 5 and spindle top 20 are provided with axial passage 18, the position that the hard mandrel is connected with spindle top is provided with through hole 22, through hole 22 1 ends are communicated with the rubber pneumatic bag inner chamber, one end is communicated with axial main shaft passage 18, the main shaft passage other end is communicated with tracheae 4 by high-speed joint 16, tracheae connects air pump 3, and main shaft is in transmission connection by belt pulley 15 and motor 2.
Rubber pneumatic bag 26 cylindrical wall are embedded with axial hard reinforcement, prevent that heave at the middle part after the air bag pressurising.
The end that the hard mandrel is connected with spindle top fixedly is equipped with mandrel chuck 21, floral disc 19 end faces that spindle top 20 is installed are provided with alignment pin 14, alignment pin inserts in the mandrel chuck 21 movingly, rotate together thereby can drive the hard mandrel, the other end of hard mandrel withstands on the live center 28 on the tail tip seat.
Knife rest 9 is enclosed within on the guide post and with the screw rod 6 parallel with the workpiece mandrel with being slidingly matched and is in transmission connection, knife bar 12 on the knife rest with can drive its radially the cam link mechanism 10 of forward and back cutter be in transmission connection, cam link mechanism and cutter motor 8 are in transmission connection, screw rod 6 with can drive its toggle that intermittently rotates 11 and be in transmission connection, toggle 11 is in transmission connection with cutter motor 8.
