Title: Improvements in broaching machines
IPC: B23D37/00
Filed: 1961-01-30
Abstract: 934,505. Broaching. LAPOINTE MACHINE TOOL CO. Ltd. Jan. 30, 1961 [March 18, 1960], No. 3433/61. Class 83 (3). A broaching machine comprises a plurality of broach hangers 12 supported by means 10 for movement in a circular path, an indexable table 32 concentric with the path, means 76 for connecting the hangers to the table and a carriage 16 for moving a hanger downwardly towards a work-table. The table 32 is rotated by an hydraulic motor through worm gearing 52. Rollers 72 on each hanger run on the rail 10 which is broken at the location of the carriage to enable a hanger to run on to the carriage and be secured thereto by a plunger 128, Fig. 5. The plunger is operated by rack and pinion gearing 145, 139, 134 which latter rod is moved by an hydraulically operated plunger. Each broach 14 is rotatably supported in its hanger and can be turned through 90 degrees as it moves on to the carriage by a plunger which can be projected outwardly from an upper support 48 to engage a double-armed lever 82, the lever being subsequently turned back to its initial position by a fixed pin as the hanger leaves the carriage. The table is locked in an indexed position by an hydraulically operated plunger, the table being located precisely before locking by a tapered plunger engaging a recess in a disc rotating with the table. The broach is retained by spring means in a head 95 on the hanger and operates a switch LS-22 which, when the broach is removed, is opened to prevent indexing of the table. Should a broach drop free when the table is being indexed, it is caught by a ledge 176 surrounded by an oil-retaining wall 177. The carriage 16 carries an adjustable stop 117 to limit its upward movement and is moved vertically to engage and disengage the broach from the hydraulically operated jaws of a puller 18, Fig. 2, by an hydraulic piston 150 moving rack-and-pinion gearing to rotate a sprocket 142 engaging chains 149 attached to the carriage. The work is clamped to a table 20 which is then moved by hydraulic pistons to centre a hole in the work and a hole 164 in the table above a hole 166 in the machine frame. The puller 18 is moved by an hydraulic piston, the speed being determined by setting various valves associated with five pumps to give speeds of 2 to 27 feet per minute. The valves are selected by manually setting a selector switch. A further selector switch determines which broaches are to be used, and which positions of the table are to be skipped. As a broach approaches the carriage 16, a cam 210 operates a switch to slow down the movement of the table. When a workpiece has been broached, the work-table is moved from its operative position, and the broach is moved rapidly upwards and mechanically reengages in the jaws of the carriage 16.
