Description

A kind of rotatable Intake shaft of compact

[technical field]

This utility model is related to air induction field in cleaning, the rotatable Intake shaft of specifically a kind of compact.

[background technology]

Existing lathe, when being carried out, for different workpieces, or the Different Plane of same workpiece or hole slot, needs Go to clean with different position angle nozzles between workpiece and nozzle.If only the motion by main shaft to switch nozzle and workpiece Angle, is each face that cannot take into account workpiece, and the time spent by motion of main shaft, can be to the whole productive temp of client Produce impact.So it is accomplished by the rotation that jig plate carries out 360 ° in cleaning process, to complete whole cleaning process.

For to clamping workpiece cylinder and for confirm workpiece whether correct seat gas inspection equipment supply, need to folder Tool plate one end setting air intake structure, and this air intake structure can coordinate the rotation of jig plate.So both can with safe way, and Do not affect jig plate to rotate.

Air inlet is set directly in L shaped plate, is connected with the air inlet on Intake shaft.Both greatlyd save space, In turn ensure that being normally carried out of cleaning.

[utility model content]

While the purpose of this utility model is exactly to solve in prior art supply, the asking of accessible rolling clamp plate Topic.On the basis of greatling save space, provide the rotation gas-supplying structure that a kind of structure is novel, safe and reliable.

For realizing object above, this utility model is achieved through the following technical solutions：

A kind of rotatable Intake shaft of compact, including Intake shaft, has the inlet channel axially penetrating through, air inlet in Intake shaft Axle is provided with 7 air inlets, and the uniform spiral type of wherein 6 air inlets is distributed in the anterior face of Intake shaft, and another enters Pore is located at the posterior face of Intake shaft, and inlet channel is connected with described air inlet, and Intake shaft rear portion may be rotatably mounted at solid In reservation, Intake shaft front portion is dismountable to be cased with a rotary liner, and rotary liner is detachably connected with fixed seat, rotary liner Inside uniformly it is intervally distributed with sealing cannelure and air inlet cannelure, rotary liner surface has threaded air inlet, rotation There is in bushing the inlet channel connecting air inlet and air inlet cannelure, in sealing cannelure, be provided with sealing ring, Intake shaft front end Be provided with end cap, end cap is fixedly connected with rotary liner front end, the tail end of Intake shaft pass through described fixed seat and with a L shaped plate Vertical section connects, and on Intake shaft, each anterior air inlet is corresponded with the air inlet cannelure on rotary liner, L-shaped Plate is provided with air inlet, and the air inlet of L shaped plate is connected by the inlet channel of setting inside L shaped plate with the air inlet at Intake shaft rear portion Connect.

Sealing cannelure uniformly spaced apart in rotary liner and air inlet cannelure are used for placing sealing ring and air inlet, Guarantee the air-tightness of air intake structure.

A bearing is installed it is ensured that it can smooth rotate between preferably described fixed seat and Intake shaft, and saves Save space.

Preferably described rotary liner is used for connecting Intake shaft and gas-tpe fitting.Described rotary liner is by bronze Material is made.Due to jig plate revolving property, described rotary liner can produce a large amount of frictions with sealing ring, and bronze material was both resistance to Mill, will not damage sealing ring it is ensured that its service life again.

Preferably described fixed seat, is used for fixing Intake shaft, and ensures position and the height of Intake shaft.

Preferably described L shaped plate, for installs fixture plate.When jig plate rotates, L shaped plate drives Intake shaft common Rotation is so as to cleaning is normally carried out.

The air inlet of L shaped plate is connected with the air inlet at Intake shaft rear portion.Both save space, and in turn ensure that cleaning just Often carry out.

Preferably described 360 ° of rotational structures of rotatable Intake shaft and A axle use cooperatively, and can meet A axle and rotate simultaneously Ensure the requirement of air inlet.

This utility model has the advantages that：1st, there are 7 air inlets, fixing true with seat for workpiece on jig plate Recognize, the air inlet cannelure on each air inlet and rotary liner corresponds, each annular air inlet duct has one threaded Air inlet, formed an independent inlet channel；2nd, Intake shaft can follow the common rotation of 360 ° of jig plate, does not affect workpiece Normal wash；3rd, venthole is set directly in L shaped plate, is connected with the air inlet on Intake shaft, form independent air inlet Passage.Both greatly save space, in turn ensure that being normally carried out of cleaning.

So on the basis of reducing space, accurate Rapid Cleaning can be carried out to the various situations of workpiece on fixture, save While time, improve cleaning efficiency.
