Description
Technical field
The utility model relates to the parts on the lathe, particularly relates to the shifting fork device on a kind of lathe.
Background technology
The shifting fork device that is contained on the lathe commonly used at present mainly contains following two kinds of modes: a kind of structure as shown in Figure 1 and Figure 2, when exterior power is passed to driving lever 2 by cam 14, driving lever 2 deflections, driving lever 2 drives connected declutch shift shaft 10, declutch shift shaft 10 is fixedlyed connected by screw 8 with handle set 9, because the plush copper 13 of handle set 9 is connected with the side groove 15 of shift fork 5, makes shift fork 5 deflections; Handle 11 is fixedlyed connected with handle set 9, and turning handle 11 when manual, drives handle set 9, makes shift fork 5 deflections.The shortcoming of this kind shifting fork device is: 1, the plush copper 13 of handle set 9 is connected with this of side groove 15 of shift fork 5, plush copper 13 fractures of handle set 9 easily take place when deflection, 2, the plush copper 13 of handle set 9 drives shift fork 5 deflections, when driving shift fork 5 deflections,, torsion seals fractureing of 6 place's axle journals because of can causing shafting oil.Another kind of structure as shown in Figure 3, Figure 4, shift fork 5 is connected with declutch shift shaft 10, on declutch shift shaft 10 axis bodies splined shaft is arranged, and the splined hole that mates with splined shaft is arranged on shift fork 5.In the time of manually, turning handle 11 through handle set 9 and the declutch shift shaft 10 of being fixedlyed connected with it by screw 8, rotates on rear axle housing 4 and front shaft sleeve 7, drives shift fork 5 deflections; Or drive by axle 1 by cam 14, make driving lever 2 drive declutch shift shafts 10 and on rear axle housing 4 and front shaft sleeve 7, rotates, shift fork 5 deflections that declutch shift shaft 10 drives are attached thereto.The shortcoming of above-mentioned shifting fork device is: when producing this shifting fork device, shift fork 5 and declutch shift shaft 10 must form a complete production network, and the cross section of the hole of shift fork 5 and declutch shift shaft 10 must be both spline shape, or are both regular hexagon, square etc., increase production technology, improved production cost.
Summary of the invention
For overcoming above-mentioned technological deficiency, the purpose of this utility model provides that a kind of not easy fracture, cost are low, the shifting fork device on a kind of lathe of reasonable in design.
The purpose of this utility model realizes by following technology path:
Shifting fork device on a kind of lathe, comprise by axle, driving lever, declutch shift shaft, handle set, handle, screw, shift fork, front shaft sleeve, shafting oil envelope, driving lever one end is by axle, handle set is fixedlyed connected by screw with declutch shift shaft one end, handle set is fixedlyed connected with handle, shift fork is provided with the hole that is complementary with declutch shift shaft, shift fork and declutch shift shaft socket, the side of wherein said driving lever is provided with a male member, male member and driving lever are integrally formed, a side in the hole that is complementary with declutch shift shaft on the shift fork is provided with groove, and the nose portion of groove and male member is pegged graft fixing.
The nose portion of described male member be shaped as cuboid, what connect driving lever one end on the male member is shaped as the cylinder bodily form.
The groove that described shift fork upside is provided be shaped as rectangular arch.
The beneficial effects of the utility model are:
1, easy fracture not: because the mode that does not adopt handle set plush copper and shift fork to join, avoided easily taking place in the prior art defective that fracture of handle set plush copper and shafting oil envelope place axle journal rupture.
2, reduce production costs: only need during production to make improvement a little to the production technology of first kind of shifting fork device in the prior art, driving lever and male member are cast as one to get final product, and need not forms a complete production network in addition has the shift fork and the declutch shift shaft of spline structure.
3, simple in structure, reasonable in design: because driving lever is to be contained on the lathe geared head by rear axle housing, front shaft sleeve and bearing in the prior art, what male member of the present utility model connected driving lever one end is shaped as the cylinder bodily form, can play the effect that substitutes bearing and rear axle housing, together shifting fork device is installed on the lathe geared head with front shaft sleeve.

The specific embodiment
Be described in further detail below in conjunction with Fig. 5-9 couple of embodiment of the present utility model:
Embodiment 1:
With reference to accompanying drawing 5,6,7,8,9, shifting fork device on a kind of lathe, it comprises by axle 1, driving lever 2, shift fork 5, shafting oil envelope 6, front shaft sleeve 7, screw 8, handle set 9, declutch shift shaft 10, handle 11, cam 14, male member 16, driving lever 2 one ends are by axle 1, handle set 9 is fixedlyed connected by screw 8 with declutch shift shaft 10 1 ends, handle set 9 is fixedlyed connected with handle 11, the hole that is complementary with declutch shift shaft 10 is arranged on the shift fork 5, shift fork 5 and declutch shift shaft 10 sockets, the side of driving lever 2 is provided with a male member 16, male member 16 is integrally formed with driving lever 2, and a side in the hole that is complementary with declutch shift shaft 10 on the shift fork 5 is provided with groove 17, and groove 17 is pegged graft fixing with the nose portion of male member 16.
The nose portion of male member 16 be shaped as cuboid, what male member 16 connected driving levers 2 one ends is shaped as the cylinder bodily form.
The groove 17 that shift fork 5 upsides are provided be shaped as rectangular arch.
The utility model is contained on the geared head 12 by male member 16, front shaft sleeve 7, when exterior power is passed to driving lever 2 by cam 14, driving lever 2 deflections, drive the male member 16 integrally formed with it, the nose portion of male member 16 drives the shift fork 5 with its grafting, because male member 16 is integrally formed with driving lever 2, male member 16 is simultaneously stressed with driving lever 2 when reversing, the distortion that male member 16 nose portion take place is little, and difficult the fracture can not sealed fractureing of 6 place's axle journals because of torsion causes shafting oil yet.
The utility model drives handle set 9 deflections by handle 11 when manual, and then drives the declutch shift shaft 10 of fixedlying connected with it, drives male member 16 then and rotates, and makes the action that shift fork 5 deflections of pegging graft are with it finished to be needed.
