Hydraulic impact device is used in a kind of assembly of shaft
Technical field
The utility model relates to shafts to assemble field, more particularly to a kind of shaft assembly hydraulic impact device.
Background technique
Shaft is the axis for not only having born moment of flexure in a kind of rotation work but also having born torque, is widely used in all kinds of transmission systems
In, the one kind of gear shaft as shaft is the important component in gear train assembly.Under normal circumstances, for the length of axis
Degree and gear shaft of the gear width ratio less than 5, can form in such a way that gear shaft integrated machine adds;5 are greater than for ratio
Gear shaft, need with shaft to process gear respectively, be then assembled into gear shaft.The gear and axis for forming gear shaft belonged to
Cooperation is crossed, there is certain assembly resistance when being assembled.Currently, the assembly of gear shaft continue to use always hammer strike, the craft that stick is hit
Assembly technology.Hammer force is excessive, if axis and gear centre line be easy to cause mating surface to dampen, influence gear and axis not to just
Concentricity, and it is difficult in disassembly;Hammer force is too small, can not overcome the resistance of transition fit, cannot complete to install, influence to fill
With efficiency.In the use occasion of batch assembly line, existing assembly technology cannot achieve mechanization, continuous production, and operator
Large labor intensity.
Summary of the invention
The purpose of this utility model is that provide a kind of shaft assembly to solve the above-mentioned problems is filled with hydraulic shock
It sets.
The utility model achieves the above object through the following technical schemes:
A kind of shaft assembly hydraulic impact device, including rack, slide rail, slide unit, pneumatic hammer, guide groove, guide groove
Bracket, the slide rail, the guide groove bracket, ring electromagnet are equipped in the rack, and the ring electromagnet is logical
Signal wire connection control platform is crossed, lead screw is installed on the slide rail, the slide unit, the cunning are installed on the lead screw
The pneumatic hammer is installed, the pneumatic hammer upper end connects the control platform, the guide groove installation by the signal wire on platform
On the guide groove bracket, the guide groove end is equipped with cylinder, is equipped with cylinder push-rod on the cylinder.
It in above structure, will be first fixed in the rack to cogged by ring electromagnet quick-clamping, then will
Shaft to be installed is inserted into the hole to cogged, pushes guide groove by the cylinder push-rod, the control platform gives the cylinder
Thrust parameter appropriate is provided, so that the guide groove and shaft reliable contacts to be installed, play the role of support and guiding, to protect
It demonstrate,proves shaft to be installed and to the concentricity requirement between cogged, slide unit described in the length adjustment then according to shaft to be installed is vertical
The height in direction contacts the pneumatic hammer just with the upper surface of shaft to be installed in vertical direction, the control platform according to
The different sizes and fit clearance for filling shaft, appropriately sized impact force is provided to the pneumatic hammer, realizes the quantization control of impact force
System, completes the accurate assembly of shaft.
In order to further increase the use function of shaft assembly percussion mechanism, the slide rail and the guide groove branch
Frame is fixed by welding in the rack, and the ring electromagnet is bolted in the rack.
In order to further increase the use function of shaft assembly percussion mechanism, the slide unit passes through with the slide rail
The positive and screw pair of guide rail connect, and the pneumatic hammer, which is bolted, to be fixed on the slide unit.
In order to further increase the use function of shaft assembly percussion mechanism, the guide groove is fixed by welding in institute
It states on cylinder push-rod, and is contacted by V-type rail pair with the guide groove bracket, fixation is bolted in the cylinder
On the guide groove bracket.
Beneficial effect is: using this percussion mechanism of pneumatic hammer carry out shaft assembly, it can be achieved that impact force parametrization
Setting guarantees assembling quality, and hammering action is automatically performed by machine, and assembly efficiency greatly improves, and assembles good product consistency,
And the support positioning of shaft and gear is automatically performed, and realizes mechanization, the continuous production of assembly.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As depicted in figs. 1 and 2, a kind of shaft assembly hydraulic impact device, including rack 1, slide rail 3, slide unit 5,
Pneumatic hammer 11, guide groove 7, guide groove bracket 9 are equipped with slide rail 3, guide groove bracket 9, ring electromagnet 12, ring in rack 1
Shape electromagnet 12 connects control platform 10 by signal wire 6, is equipped with lead screw 4 on slide rail 3, is equipped with slide unit on lead screw 4
5, pneumatic hammer 11 is installed, 11 upper end of pneumatic hammer connects control platform 10 by signal wire 6, and guide groove 7 is mounted on guide groove on slide unit 5
On bracket 9,7 end of guide groove is equipped with cylinder 2, and cylinder push-rod 8 is equipped on cylinder 2.
In above structure, it will be first fixed in rack 1 to cogged by 12 quick-clamping of ring electromagnet, it then will be to
Dress shaft is inserted into the hole to cogged, pushes guide groove 7 by cylinder push-rod 8, control platform 10 provides appropriate to cylinder 2
Thrust parameter so that guide groove 7 and shaft reliable contacts to be installed, play the role of support and guiding, with guarantee shaft to be installed with
Slide unit 5 is adjusted in the height of vertical direction, is made then according to the length of shaft to be installed to the concentricity requirement between cogged
Pneumatic hammer 11 is just contacted in vertical direction with the upper surface of shaft to be installed, control platform 10 according to the different sizes of shaft to be installed and
Fit clearance provides appropriately sized impact force to pneumatic hammer 11, realizes the quantified controlling of impact force, completes the accurate dress of shaft
