Description
Technical field
The utility model belongs to a kind of pulling device that opens of machine components, specifically, relates to a kind of pulling device that opens of taper key.
Background technology
In mechanical field, there is situation in the equipment of many types such as motor, blower fan belt pulley with the taper key securing part.When these equipment need be dismantled; technical staff or maintenance personal can select with hammer vertically usually; and insert opposite direction with taper key and knock method with the taper key parts in contact, reach the purpose of dismounting, do like this and cause the damage of being knocked parts easily.For example, when dismounting blower fan belt pulley, technical staff or maintenance personal can directly knock belt pulley vertically, and the material of belt pulley is a cast iron, and material is more crisp, is unable to undergo to knock.In addition, with the fastening parts area of taper key hour, also be difficult for knocking.If technical staff or maintenance personal adopt the mode of knocking to dismantle by force, the then easier damage that causes parts.In a word, adopt the mode of knocking to dismantle and damage parts easily with the fastening parts of taper key.
The utility model content
Technical problem to be solved in the utility model provides the taper key pulling device of a kind of dismounting by the fastening parts of taper key, and this device can be avoided the damage with the fastening parts of taper key.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of taper key pulling device, described taper key pulling device is formed by opening to pull out bolt, last locating piece, following locating piece and be connected locking member; On the last locating piece one side relative with following locating piece the fracture that blocks taper key is arranged, last locating piece is realized connecting by being connected locking member with following locating piece, is furnished with to open on last locating piece and pulls out bolt, opens the direction that is provided with of pulling out bolt and is parallel to the taper key exit axis.
One counterbore locating slot is arranged in the fracture of the last top locator block of taper key pulling device.
Position corresponding to last locating piece fracture on the following locating piece of taper key pulling device is provided with a boss.
Have in the boss of the following locating piece of taper key pulling device one in fracture the through hole of taper key, screw in through hole that fishbolt, the end face of fishbolt are arranged is the plane
The opening of taper key pulling device pulled out bolt and be evenly distributed to few two around fracture on last locating piece.The connection locking member of taper key pulling device is bolt or locking grab.
In adopting the fastening device of taper key, taper key stressed is divided into the pressure of vertical direction and the frictional force when moving horizontally.When horizontal direction moved taper key, the pressure of vertical direction was much larger than the frictional force of horizontal direction, this just for manpower realize opening pull out that taper key provides may.With upper and lower locating piece with behind the taper key location, with connecting the locking member locking, pull out bolt and finish to open and pull out by opening at last, thereby avoided going to knock the parts that link to each other with taper key and cause damage, this apparatus structure is simple, and is easy to use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the front view of the utility model taper key pulling device;
Wherein: 1-connects clamping screw; Locating piece under the 2-; The last locating piece of 3-; 4-opens and pulls out bolt; 5-counterbore locating slot; 6-buckle taper key; 7-is the buckle taper key not; The 8-boss; The 9-fishbolt
Fig. 2 is the front view of the another kind of structure of last locator in the utility model taper key pulling device.
Fig. 3 is a longitudinal sectional drawing of going up locating piece shown in Figure 2.
Fig. 4 is the front view of buckle taper key.
Fig. 5 is the front view of buckle taper key not.
The specific embodiment
As shown in Figure 1, the taper key pulling device pull out bolt 4 by opening, go up locating piece 3, locating piece 2 and be connected clamping screw 1 etc. and form down.Have screw on the last locating piece 3, be used for screwing in to open pulling out bolt 4.On the relative one side of last locating piece 3 and following locating piece 2 the fracture A that blocks taper key is arranged, last locating piece 3 connects by being connected clamping screw 1 with following locating piece 2.
The concrete course of work of this device is at first will go up locating piece 3 to place the taper key top, and taper key is stuck among the fracture A, will descend locating piece 2 to place the taper key below then, will go up locating piece, following locating piece and taper key by connection clamping screw 1 and connect as one.When rotation is opened when pulling out bolt 4, manpower pulls out bolt 4 and acts on the fastening parts of taper key by opening, and last locating piece, locating piece and taper key are then mobile in opposite direction down.
What above-mentioned connection locking member adopted is the form that connects clamping screw 1, be to have through hole at following locating piece 2 two ends, and have the corresponding hole of through hole on the last locating piece 3 with following locating piece, by from screwing in connection clamping screw 1 the locating piece through hole down, can connect as one going up locating piece, following locating piece and taper key.
Referring to Fig. 2 and Fig. 3, also can establish a counterbore locating slot 5 at the fracture A top of last locating piece 3.When taper key is buckle, buckle taper key 6 as shown in Figure 4, rotation is opened when pulling out bolt 4, opens and pulls out bolt 4 and move inward, and counterbore locating slot 5 can guarantee that buckle taper key 6 outwards moves with upper and lower locating piece.Especially when taper key not buckle the time, not buckle taper key 7 as shown in Figure 5, counterbore locating slot 5 can be located taper key, avoids in motion process, and taper key rotates.
Open and pull out bolt 4 be furnished with various ways on last locating piece 3, pull out bolt horizontal symmetrical on last locating piece and be arranged as goodly but open with two, open when pulling out bolt when rotation simultaneously, manpower can farthest pull out bolt effect and taper key by opening.Open when pulling out bolt and also being not enough to extract taper key when two, can arrange that one is opened and pulls out bolt 4 at the top of last locating piece again, rotation simultaneously earlier is positioned at same horizontal two opens and pulls out bolt, rotates opening of top again and pulls out bolt, repeat this two steps, be pulled out up to taper key.
When the taper key height less than fracture A when height, can establish a boss 8 on the locating piece down, this boss 8 is corresponding with the fracture A position of last locating piece, is used for the clamping taper key.The also available fishbolt of this boss 8 substitutes, and has a through hole in the corresponding position of fracture of locating piece down and last locating piece, by this hole, can screw in fishbolt, with fixing taper key.When the taper key height much smaller than the fracture height, when boss 8 is difficult to fixedly taper key, also can on boss 8, open a through hole, fix taper key by screwing in fishbolt 9.
When the end face of fishbolt 9 is the plane, because of the contact-making surface of itself and taper key is big, so in mechanism, the frictional force between it and taper key is just big, can more effective fixedly taper key and open pulling device.
The utility model is not limited to the above-mentioned specific embodiment.For example, upper and lower locating piece can be locked upper and lower locating piece by grab, and not adopt bolt by at two STHs.So long as adopt open pull out bolt, go up that locator, lower locating device and positioner form opens pulling device all within protection domain of the present utility model.
