Description
Technical Field
The utility model relates to a lathe drilling equipment specifically is an automatic drilling equipment of center lathe.
Background
At present, machining of inner cavity holes of parts of lathes manufactured at home and abroad is uniformly completed by utilizing a tailstock, a centre is detached, a drill bit is installed in the centre hole, and the tailstock roller is manually rotated to complete machining of the inner cavity holes of the parts. The processing method has the disadvantages of very complicated operation process, long preparation time of an operator, very labor-consuming manual operation required in the processing process of the operator, complicated operation process, low processing efficiency, low processing precision and incapability of accurately drilling the eccentric hole.
Disclosure of Invention
The utility model discloses a solve the problem that current lathe drilling machining efficiency is low, the machining precision is low, provide an automatic drilling equipment of center lathe.
The utility model discloses an adopt following technical scheme to realize: the automatic drilling device of the common lathe comprises a support arranged on a tool rest of the lathe, wherein a stop block is arranged at the front end of the support, the bottom of the support is fixedly connected with the tool rest of the lathe through a bolt, a taper hole is formed in the front end of the support, a screw hole is formed in the rear end of the taper hole, the center line of the taper hole is coaxial with the center line of a drill bit of the lathe, a drill bit taper sleeve is inserted into the taper hole, a drill bit taper sleeve inner hole is formed in the front end of the drill bit taper sleeve, a key groove is formed in the middle of the drill bit taper sleeve.
When the lathe is used, the central line of the taper hole is coaxial with the central line of a drill bit of the lathe, so that the center of the drill bit is coaxial with the center of the chuck. The bolt connection and the screw rod and screw hole connection are used for conveniently disassembling the support and the taper sleeve.
The utility model has the advantages as follows: utilize reasonable structural design to realize the automatic drilling function of center lathe. The utility model discloses machining precision is high, machining efficiency is high, and the range of application is extensive. Utilize the utility model discloses the hole size precision that processing was accomplished reaches IT9, and roughness is Ra3.2 to saved the manual work, realized the function of the automatic drilling of lathe, former manual brill during processing product, reaming time are 10 minutes, and brill after the improvement, reaming time are 8 minutes, and hole machining efficiency improves 20%.
Drawings
FIG. 1 is a schematic view of the structure of the support of the present invention;
fig. 2 is a schematic structural diagram of a drill bit taper sleeve.
In the figure: 1-support, 2-taper hole, 3-stop block, 4-bolt connection, 5-drill bit taper sleeve, 6-drill bit taper sleeve inner hole, 7-key groove and 8-screw rod.
Detailed Description
Automatic drilling equipment of engine lathe, including installing support 1 on the knife rest of lathe, 1 front end of support is equipped with dog 3, 1 bottom of support is fixed through bolted connection 4 with the knife rest of lathe, 1 front end of support is opened there is taper hole 2, 2 central lines of taper hole are coaxial with the drill bit central line of lathe, 2 rear ends of taper hole are opened there is the screw, taper hole 2 is inserted drill bit taper sleeve 5, 5 front ends of drill bit taper sleeve are opened drill bit taper sleeve hole 6, 5 middle parts of drill bit taper sleeve are equipped with keyway 7, 5 rear ends of drill bit taper sleeve are equipped with screw rod 8 with the screw-hole complex of support 1.
In the specific implementation process, the conical surfaces of the taper hole 2 and the drill bit taper sleeve 5 are No. 6 Morse tapers. The bolt connection 4 at the bottom of the support 1 adopts an M16 bolt, and the stop block is 5mm thick and is used for preventing the device from being separated from the tool rest due to excessive drilling force during drilling. By utilizing the automatic drilling device and adopting a clamping method of four jaws of a lathe with adjustable axes, the processing of the eccentric hole of the part with smaller eccentric size can be realized.
