Abstract
The invention discloses a disassembling device of a grinding tool for a hollow shaft. The disassembling device comprises a pull rod, a locating baffle, a locking nut, supports and hydraulic cylinders. One end of the pull rod is a small column with the diameter of one end smaller than the diameters of the other portions of the pull rod; and the locking nut is screwed on the small column in a sleeving manner and tightly presses the locating baffle. A sleeve hole which can be arranged on a locating shaft core in a sleeving manner is formed in the other end of the pull rod in the axial direction, and pin shaft holes penetrating the sleeve hole are formed in the other end of the pull rod in the radial direction. The two sides of the pull rod are each provided with one support, back end covers of the hydraulic cylinders are fixed to the supports, and piston rods of the hydraulic cylinders horizontally extend out and correspond to the locating baffle. When the locating shaft core is disassembled, the pull rod is inserted into the outer circle of the locating shaft core, a pin shaft penetrates the corresponding pin shaft hole of the pull rod and one pin shaft hole in the locating shaft core, the piston rods of the hydraulic cylinders horizontally extend out to abut against the locating baffle, the locating baffle drives the pull rod to move outwards, then the locating shaft core is pulled out of the hollow shaft, the locating shaft core can be completely disassembled and can be reused, and the use cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of detaching equipment, particularly relate to a kind of hollow shaft grinding frock detaching equipment.
Background technology
Often need in machine-building to process hollow shaft type parts.Dimensional accuracy and the high hollow shaft type parts work in-process of roughness requirements need just can complete through grinding.Because the general wall thickness dimension of hollow shaft type parts is less, clamping difficulty, and easily deform.In order to ensure to process the part meeting designing requirement, often need to design the mill machining tool fixture be fixed on by hollow shaft type parts on grinding machine positioning center hole.
Mill machining tool fixture mainly adopts two locating shaft cores, and the outer face of locating shaft core centrally line arranges center positioning hole.When using this mill machining tool fixture, first in the two ends of hollow shaft part to be ground, squeeze into locating shaft core with similar instruments such as iron hammers respectively, then the center positioning hole of locating shaft core is fixed by the top on grinding machine.
After hollow shaft is ground processing, the locating shaft core in this hollow shaft two ends endoporus need be taken out.In prior art, the normal outside welding steel adopted at locating shaft core, steel plate is welded with the block beaten for iron hammer, using the provision for disengagement as processing tool of the steel plate of welding and baffle plate.What operator exerted oneself beats baffle plate, and the locating shaft core that baffle plate is connected with steel plate in stressed lower drive outwards exits.Above-mentioned employing welding steel and block, and beat the mode that block exits locating shaft core and mainly there is following defect: when dismantling this locating shaft core, need on locating shaft core welding steel and block, steel plate and baffle plate and locating shaft core connect as one, both make locating shaft core not reuse, and cause again processing cost to increase.
Summary of the invention
For above shortcomings in prior art, the invention provides a kind of reusable, the hollow shaft grinding frock detaching equipment that use cost is lower.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
Hollow shaft grinding frock detaching equipment, comprises pull bar, positioning baffle, locking nut, bearing and hydraulic cylinder; One end of described pull bar is the small column that diameter is less than pull bar remainder diameter, and described small column is provided with external screw thread; Described positioning baffle has a centre bore, and positioning baffle is enclosed within the small column of pull bar by this centre bore, and described locking nut rotation set is on small column and compress positioning baffle; The other end of described pull bar arranges the trepanning that can be enclosed within locating shaft core vertically, and the other end of described pull bar arranges the pin shaft hole running through trepanning in radial directions; The both sides of described pull bar are fixedly installed a bearing respectively, and hydraulic cylinder placed by described bearing, and the rear end cap of described hydraulic cylinder is fixed on bearing, and the piston rod level of hydraulic cylinder is stretched out and corresponding with positioning baffle.
As a preferred embodiment of the present invention, the inner circle of the other end of described pull bar is in axial direction symmetrical arranged convex tendon, described convex tendon and pin shaft hole distribute in 90 degree in radial directions.
As another kind of preferred version of the present invention, the other end 5 ~ 10mm of described pin shaft hole distance pull bar.
The invention has the beneficial effects as follows: during dismounting locating shaft core, pull bar is inserted on the cylindrical of locating shaft core, bearing pin is through the pin shaft hole on pull bar and locating shaft core, the piston rod level of hydraulic cylinder is stretched out and is withstood on positioning baffle, and positioning baffle drives pull bar to move laterally, and then is pulled out in hollow shaft by locating shaft core, then bearing pin is exited in the pin shaft hole locating shaft core and pull bar, locating shaft core just can be complete disassemble, reusable, greatly reduce use cost.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
As shown in Figure 1, 2, hollow shaft grinding frock detaching equipment, comprises pull bar 1, positioning baffle 2, locking nut 3, bearing 5 and hydraulic cylinder 6.One end of pull bar 1 is the small column 4 that diameter is less than pull bar 1 remainder diameter, and small column 4 is provided with external screw thread.Positioning baffle 2 has a centre bore, and positioning baffle 2 is enclosed within the small column 4 of pull bar 1 by this centre bore, and locking nut 3 rotation set is on small column 4 and compress positioning baffle 2.The other end of pull bar 1 arranges the trepanning 7 that can be enclosed within locating shaft core vertically, and the other end of pull bar 1 arranges the pin shaft hole 8 running through trepanning 7 in radial directions.The both sides of pull bar 1 are fixedly installed a bearing 5 respectively, bearing 5 are placed hydraulic cylinder 6, and the rear end cap of hydraulic cylinder 6 is fixed on bearing 5, and piston rod 9 level of hydraulic cylinder 6 is stretched out and corresponding with positioning baffle 2.
