Abstract
The utility model relates to a component on a machine tool, in particular to a pulling fork device arranged on a machine tool, comprising a depending shaft, a deflector rod, a pulling fork shaft, a rear axle sleeve, a front axle sleeve, a handle seat, a handle, a screw and a pulling fork. One end of the deflector rod is the depending shaft; the deflector rod is sheathed on the spindle box of the machine tool by the rear axle sleeve and the front axle sleeve; the handle seat and one end of the pulling fork shaft is fixedly connected by the screw; the handle seat and the handle is fixedly connected. The utility model is characterized in that the pulling fork is connected with the pulling fork shaft; the shaft body of the pulling fork shaft is provided with a transmission body; the pulling fork is provided with a hole matched with the transmission body. The utility model has the advantages that the pulling fork shaft directly drives the matched and connected pulling fork thereof, and the transmission and sealing are reliable.
Description
Technical field
The utility model relates to the parts on the lathe, specifically is a kind of shifting fork device that is contained on the lathe.
Background technology
The shifting fork device of existing lathe, Fig. 1, Fig. 2 are its structural representations.Exterior power is passed to driving lever 2 by cam 14, makes driving lever 2 deflections, and driving lever 2 drives connected declutch shift shaft 9, and declutch shift shaft 9 is fixedlyed connected by screw 7 with handle set 8, because the plush copper 12 of handle set 8 is connected with the side groove 11 of shift fork 4, makes shift fork 4 deflections.Plush copper 12 fractures of handle set 8 easily take place in this connection, or service time is than long recess 11, plush copper 12 wearing and tearing, the gap increases, influence the deflection angle of shift fork 4, make processed part in addition not reach processing request, and the plush copper 12 of handle set 8 drives shift fork 4 deflections, when driving shift fork 4 deflections, seals fractureing of 5 place's axle journals because of torsion can cause shafting oil.
Summary of the invention
The utility model purpose is or not directly to stir shift fork at above-mentioned declutch shift shaft, and the shifting block fracture of handle set and the defective that shafting oil envelope place axle journal ruptures easily take place.The utility model purpose is such realization: it is by forming by axle, driving lever, declutch shift shaft, rear axle housing, front shaft sleeve, handle set, handle, screw, shift fork, driving lever one end is by axle, driving lever is contained on the lathe geared head by rear axle housing, front shaft sleeve, handle set is fixedlyed connected by screw with declutch shift shaft one end, handle set is fixedlyed connected with handle, it is characterized in that described shift fork is connected with declutch shift shaft, being has transmission body on the declutch shift shaft axis body, and the hole with the transmission body coupling is arranged on shift fork.
Transmission body is a splined shaft on the described declutch shift shaft, and the splined hole with the splined shaft coupling is arranged on shift fork.Transmission body is that section is a regular hexagon on the described declutch shift shaft, and the regular hexagon endoporus that mates with regular hexagon is arranged on shift fork, and transmission body is that section is a square on the described declutch shift shaft, and the square endoporus with the square coupling is arranged on shift fork.
Accompanying drawing title and explanation thereof

The symbol of figure and explanation thereof: the 1st, by axle, the 2nd, driving lever, the 3rd, rear axle housing, the 4th, shift fork, the 5th, shafting oil envelope, the 6th, front shaft sleeve, the 7th, screw, the 8th, handle set, the 9th, declutch shift shaft, the 10th, handle, the 11st, groove, the 12nd, plush copper, the 13rd, geared head, the 14th, cam.
The specific embodiment
Set forth an embodiment of the present utility model below in conjunction with accompanying drawing.It is by leaning on axle 1, driving lever 2, rear axle housing 3, shift fork 4, shafting oil envelope 5, front shaft sleeve 6, screw 7, handle set 8, declutch shift shaft 9, handle 10 is formed, fixedly connected with driving lever 2 one ends by axle 1, driving lever 2 other ends are fixedlyed connected with declutch shift shaft 9, rear axle housing 3 is on driving lever 2, shift fork 4 is connected with declutch shift shaft 9, handle set 8 is fixedlyed connected by screw 7 with declutch shift shaft 9 other ends, front shaft sleeve 6 is arranged on handle set 8, shafting oil envelope 5 is contained between handle set 8 and the declutch shift shaft 9, handle 10 is fixedlyed connected with handle set 8, on declutch shift shaft 9, spline is arranged, the splined hole of its coupling is arranged on the slotted hole of shift fork 4.
The utility model is contained on the geared head 13 by rear axle housing 3, front shaft sleeve 6, in the time of manually, as long as turning handle 10 through handle set 8 and the declutch shift shaft 9 of being fixedlyed connected with it by screw 7, rotates, drives shift fork 4 deflections on rear axle housing 3 and front shaft sleeve 6; Or drive by axle 1 by cam 14, make driving lever 2 drive declutch shift shafts 9 and on rear axle housing 3 and front shaft sleeve 6, rotate.Declutch shift shaft 9 drives shift fork 4 deflections that are attached thereto, and finishes the action that needs.
The beneficial effects of the utility model are shift forks 4 that declutch shift shaft 9 direct drives are connected with it, and transmission and sealing are reliable.
