Abstract
The utility model provides a clamp for a gear hob. The clamp comprise a hob mandrel assembly and a tip press plate assembly, wherein the hob mandrel assembly comprises a hob mandrel and a connection seat, a conical through hole is positioned in the connection seat, a conical section is arranged on the hob mandrel, the conical section of the hob mandrel is sleeved in the conical through hole of the connection seat, two ends of the hob mandrel extend out of the connection seat, the centre press plate assembly comprises a press plate and a centre, a horizontal through hole is positioned in the press plate, one end of the centre is sleeved in the horizontal through hole of the press plate, a threaded hole is positioned on the circumferential surface of the press plate, a circle of groove is positioned on the circumferential surface of the centre, the cross section of the groove is in an arc shape, and the groove corresponds to the through hole of the press plate. The clamp can save time for manually rotating a nut up and down, greatly reduces labor consumption of operation workers and smoothly achieves the lean production scheme of one worker multiple machines.
Description
Technical field
The utility model relates to a kind of gear fixture, relates in particular to a kind of fixture for gear teeth.
Background technology
The motorcycle operative gear is less because of endoporus, original gear-hobbing clamp adopts the nut compressing formula, mandrel is packed into needs to be with top board after the gear hobbing blank, be wrenched again nut compressing, must pull again loose nut after gear hobbing is complete and take away pressing plate, the non-cutting time of up and down part is longer, and labor strength and physical demands are larger, and production efficiency is on the low side.
The utility model content
The technical problem that the utility model solves is: provide installation and debugging convenient, save and produce non-cutting time, improve gear hobbing production efficiency, a kind of fixture for gear teeth that reduces production costs.
The technical solution of the utility model is: a kind of fixture for gear teeth, comprise the combination of gear hobbing mandrel and the combination of top pressing plate, described gear hobbing mandrel combination comprises gear hobbing mandrel and Connection Block, described Connection Block is provided with cone-type piercer, described gear hobbing mandrel is provided with conical section, the conical section of described gear hobbing mandrel is set in the cone-type piercer of described Connection Block, and described Connection Block is extended at the two ends of gear hobbing mandrel.
Top pressing plate combination comprises pressing plate and top, described pressing plate is provided with the level perforation, a described top end is set in the level perforation of described pressing plate, the periphery of described pressing plate is provided with screwed hole, described top periphery is provided with a circle groove, the cross section of this groove is circular arc, and corresponding with the perforation of described pressing plate.
The perforation of the level of described pressing plate is provided with steel ball, and the part spheroid of steel ball is placed in described top circular groove, and a screw screws in the screwed hole of pressing plate and withstands described steel ball.
The beneficial effects of the utility model are:
when using the utility model, a top end is contained on the support of lathe, utilize downforce top on the lathe support arm and thrust ball bearing to compress product, cancelled the action that hand is pulled screw cap rotating impacted, because the perforation of the level of described pressing plate is provided with steel ball, the part spheroid of steel ball is placed in described top circular groove, one screw screws in the screwed hole of pressing plate and withstands described steel ball, thereby having guaranteed that gear hobbing mandrel combination and top pressing plate are combined in when separating pressing plate can landing, thereby saved upper assistant and pulled the rotary nut time, greatly reduce operator's physical demands, realize smoothly the lean production scheme of people's multimachine.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is gear hobbing mandrel combination schematic diagram of the present utility model;
Fig. 3 is top pressing plate combination schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to Fig. 1～Fig. 3, a kind of fixture for gear teeth, comprise the combination 1 of gear hobbing mandrel and top pressing plate combination 2, described gear hobbing mandrel combination 1 comprises gear hobbing mandrel 3 and Connection Block 4, Connection Block 4 is provided with cone-type piercer, described gear hobbing mandrel 3 is provided with conical section, and the conical section of described gear hobbing mandrel 3 is set in the cone-type piercer of described Connection Block 4, and described Connection Block 4 is extended at the two ends of gear hobbing mandrel 3.Top pressing plate combination 2 comprises pressing plate 5 and top 6, described pressing plate 5 is provided with the level perforation, an end of described top 6 is set in the level perforation of described pressing plate 5, the periphery of described pressing plate 5 is provided with screwed hole, described top 6 periphery is provided with a circle groove, the cross section of this groove is circular arc, and corresponding with the perforation of described pressing plate 5.Because the perforation of the level of described pressing plate 5 is provided with steel ball 7, the part spheroid of steel ball 7 is placed in described top 6 circular groove, one screw 8 screws in the screwed hole of pressing plates 5 and withstands described steel ball 7, and pressing plate 5 can landing when separating thereby guaranteed gear hobbing mandrel combination 1 and top pressing plate combination 2.
Referring to Fig. 3, when using the utility model, product 9 is set on gear hobbing mandrel 3, top 6 one ends are set on the support of lathe, utilize on the lathe support arm top 6 downforce and thrust ball bearing 10 to compress products 9, just can process product 9.
