Abstract
The utility model provides a multi-stage variable-speed three-head threading machine for pipe components. A gearbox of a threading machine is additionally connected with a change gear set which is formed by the mesh connection of a driving change gear and a driven change gear. A trigeminy slip gear set of the gearbox is connected with the change gear set first, and then, is connected with an output gear set of the gearbox. The combined variable speed of the change gear set and the trigeminy slip gear set can realize the multi-stage conversion of the rotary speed of a main threading shaft through changing the driving change gear and the driven change gear. The utility model has the advantage of novel structure, is suitable for the screw-thread processing of the pipe components of three-ways, elbow pipes, straight pipes, etc., and relates to a novel pipe-component processing machine.
Description
The utility model relates to a kind of pipe fitting machined machinery, especially a kind of three first tap silk lathes that are used for the processing of pipe fitting screw thread.
In known technology, three tapping machines of existing pipe fitting mainly are to be connected to form by motor, gearbox, range controlling mechanism and three tapping main spindle boxes.But because the gearbox of existing tapping machine is three shifting slide gear group speed changing structures, the tapping main shaft that is connected only has three grades of rotating speeds, cause the high speed type can not process bigger pipe fitting, and that the low speed type is processed less pipe fitting efficient is lower, so because the tapping number of spindle speeds is few, its accommodation is little, the screw thread of pipe fitting is processed be restricted, and brings inconvenience to use.
The purpose of this utility model provides three tapping machines of a kind of improved pipe fitting, makes its novel structure, the tapping number of spindle speeds is many, the scope of application is big, and the working (machining) efficiency height is easy to use.
For achieving the above object, the technical solution adopted in the utility model is: gearbox is added having connected is meshed by active change gear and driven change gear is connected the change gear group of being formed, make three shifting slide gear groups of gearbox connect earlier the output gear wheels that connect gearbox after the change gear group again, connect range controlling mechanism and three tapping main spindle boxes respectively by gearbox output gear group.By the driving and driven change gear of conversion,, realize that the tapping main shaft is by the multistage conversion of low speed to high speed by change gear group and the combined speed change of three shifting slide gear groups.During use; according to the needs that are threaded the processing pipe fitting; at speed of mainshaft requirement; active, the driven gear of corresponding earlier allotment change gear group; actuating motor is passed to gearbox with power; by the forward of installing in the gearbox, oppositely and brake the clutch for clutch control mechanism that three electromagnetic clutch form and control; again by after three shifting slide gear groups and the change gear group speed change; drive range controlling mechanism and three tapping main spindle boxes respectively by gearbox output gear group, carry out the processing operation automatically continuously of tapping, withdrawing, shutdown.
Because gearbox of the present utility model has adopted the multi-stage speed-changing structure of change gear group and the combined speed change of three shifting slide gear groups, make that the tapping main shaft can be by low speed to carrying out multistage conversion at a high speed.Therefore, the utility model than existing three tapping machine novel structures, reasonable in design, can improve working (machining) efficiency greatly, enlarged range of application, easy to use.It is applicable to the screw thread processing of threeway, elbow, pipe fitting such as straight-through, also can be applicable to the die head threading machine of processing external fiber tube spare, is a kind of novel pipe fitting processing equipment.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
Fig. 2 is the concrete structure figure of gearbox part in the utility model.
As accompanying drawing 1, embodiment illustrated in fig. 2, the utility model is to connect gearbox by motor (1), and gearbox connects range controlling mechanism (4) again respectively and 3 tapping main spindle boxes (7) are formed.Gearbox comprises: casing (5), clutch for clutch control mechanism (9), three shifting slide gear groups (8), output gear wheels (6) and the change gear group that is connected with a joggle and is formed by active change gear (2) and driven change gear (3).The change gear assembling is connected in the external wheel shaft head of gearbox body (5), and promptly initiatively change gear (2) load is on the driven gear shaft of three shifting slide gear groups (8), and driven change gear (3) load is on the driving gear shaft of gearbox output gear wheels (6).Make three shifting slide gear groups of gearbox connect the output gear wheels again after the connection change gear group speed change earlier.Therefore, a pair of change gear just can be realized six grades of rotating speeds of tapping main shaft.Match and connect the multistage conversion just can realize the tapping main shaft many different change gear correspondences is joined, to satisfy the process requirements of tapping machine.
