Abstract
The utility model discloses a centre and mandrel connection structure of a relief grinding machine. The centre and mandrel connection structure of the relief grinding machine comprises a centre, a mandrel and a connection shifting fork used for connecting the centre and the mandrel. A positioning hole which is matched with the centre is arranged on the end face of the mandrel. A shaft rod of the centre is a cylinder rod. A connection sleeve is arranged at one end of the connection shifting fork, wherein the connection sleeve is sleeved on the middle portion of the shaft rod of the centre. The other end of the connection shifting fork is fixedly connected with the mandrel. Radial thread through holes are formed in the connection sleeve, wherein the radial thread through holes are matched with fastening screws and are used for fixing the connection sleeve on the shaft rod of the centre. According to the centre and mandrel connection structure of the relief grinding machine, the shaft rod of the centre is a cylinder rod with a constant diameter, the connection shifting fork is sleeved on the shaft rod of the centre through the connection sleeve, when the specifications and models of mandrels are different or matching length of the mandrel and the centre changes, the connection sleeve is capable of moving on the shaft rod of the centre, and therefore the matching of the centre and the mandrel is guaranteed.
Description
Technical field
The utility model relates to the syndeton between the top and axle of a kind of Special Turbine Grinding Machine.
Background technology
Existing Special Turbine Grinding Machine top with axle between continuous by being connected shift fork, an end that connects shift fork is provided with adapter sleeve, adapter sleeve be sleeved on top on, and by being arranged on the shaft shoulder and the radial screw location on top, connecting the shift fork other end is fixedly connected on the axle, in workpiece process, make axle and top synchronous rotation.
Yet, because the specification of axle is varied, is arranged on the axle end face and is used for also varying with the size of the top locating hole that cooperates, cause axle and length of fit between top to change, give axle and top between installation locate and cause difficulty; In addition, radial screw adopts outer-hexagonal bolts and stretches out the periphery wall of adapter sleeve, causes easily in the course of the work security incident, causes damage for enterprise and personnel.
Given this, the utility model be intended to explore a kind of Special Turbine Grinding Machine top with the axle syndeton, this Special Turbine Grinding Machine is top can be made things convenient between the axle of top and different model and can cooperate easily with the axle syndeton, and can avoid security incident hidden danger.
Summary of the invention
The technical problems to be solved in the utility model be propose a kind of Special Turbine Grinding Machine top with the axle syndeton, this Special Turbine Grinding Machine is top can be made things convenient between the axle of top and different model and can cooperate easily with the axle syndeton.
Realize above-mentioned technical purpose, top and the axle syndeton of Special Turbine Grinding Machine of the present utility model, comprise top, axle and be used to connect the shift fork that is connected top and axle, the end face of described axle is provided with and the top locating hole that cooperates, described top axostylus axostyle is cylindrical bar, one end of described connection shift fork is provided be used to the adapter sleeve that is sleeved on top axostylus axostyle middle part, the other end is fixedly connected with described axle, and described adapter sleeve is provided with for cooperating with trip bolt and adapter sleeve being fixed on radially tapped through hole on the top axostylus axostyle.
Further, uniform being arranged on the adapter sleeve of described radially tapped through hole annular.
Further, the periphery wall of described adapter sleeve is provided with the counterbore coaxial with described radially tapped through hole.
Further, described trip bolt is soket head cap screw.
The beneficial effects of the utility model are:
Special Turbine Grinding Machine of the present utility model is top to be set to the cylindrical bar of constant diameter with the axle syndeton by top axostylus axostyle, connecting fork is sleeved on the top axostylus axostyle by adapter sleeve, when the specifications and models of axle different or and top between length of fit when changing, adapter sleeve can be mobile at top axostylus axostyle, to guarantee the cooperation between top and the axle.
Description of drawings
Fig. 1 is the top structural representation with axle syndeton embodiment of the utility model Special Turbine Grinding Machine.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
As shown in Figure 1, the structural representation of and axle syndeton embodiment top for the utility model Special Turbine Grinding Machine.Top and the axle syndeton of the Special Turbine Grinding Machine of present embodiment, comprise top 1, axle 2 be used to connect top 1 with axle 2 be connected shift fork 3, the end face of axle 2 is provided with and top 1 locating hole that cooperates, top 1 axostylus axostyle 1a is cylindrical bar, an end that connects shift fork 3 is provided be used to the adapter sleeve 3a that is sleeved on top axostylus axostyle 1a middle part, the other end is fixedly connected with axle 2, and adapter sleeve 3a is provided with for cooperating with trip bolt 4 and adapter sleeve 3a being fixed on radially tapped through hole 5 on the top axostylus axostyle 1a.By trip bolt 4 and the threaded engagement fastening effect between the tapped through hole 5 radially, adapter sleeve 3a can be fixed on the top axostylus axostyle 1a, adapter sleeve 3a can not become flexible in the Special Turbine Grinding Machine operation process.
The Special Turbine Grinding Machine of present embodiment is top to be set to the cylindrical bar of constant diameter with the axle syndeton by top 1 axostylus axostyle 1a, connecting fork 3 is sleeved on by adapter sleeve 3a on top 1 the axostylus axostyle, when the specifications and models of axle 2 different or and the length of fit between top 1 when changing, adapter sleeve 3a can be mobile at top axostylus axostyle 1a, and then utilize trip bolt 4 and the threaded engagement between the tapped through hole 5 radially, adapter sleeve 3a is fixed on the top axostylus axostyle, with guarantee top 1 and different axle 2 between cooperation.
Further, uniform being arranged on the adapter sleeve 3a of tapped through hole 5 annular radially are in order to increase the coordinate force between adapter sleeve 3a and the top axostylus axostyle 1a, radially tapped through hole 5 is set to a plurality of, simultaneously, by inciting somebody to action radially uniform being arranged on the adapter sleeve 3a of tapped through hole 5 annulars, can guarantee stress equalization.
Further, the periphery wall of adapter sleeve 3a is provided with the counterbore 5a coaxial with tapped through hole radially 5, and trip bolt 4 is soket head cap screw, adopts radially tapped through hole 5 and the trip bolt 4 of this structure, and tapped through hole 5 causes potential safety hazard can to prevent trip bolt 4 from stretching out radially.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
