Definitions
- the invention relates to a tool for machining bearing points of shafts, in particular camshafts, with the features of the preamble of claim 1.
- Such Tool is known from US-B-6,431,954.
- the invention is therefore based on the object, a tool to prepare for machining, with which the Wave can be processed faster, with the machine Effort should be low.
- the tool according to the invention can thus simultaneously the bearings machined and the cams or sealing seats be deburred.
- the workpiece does not have to be in one special, intended for deburring Used processing device and this removed again become.
- the processing element with which the Bearing is processed, and the deburring tool, with in which the cams and sealing seats are deburred at one be provided common tool or on a Processing tongs can be arranged, which are the shaft between them receives.
- the tool according to the invention is for everyone Wave types usable. The following is mainly on Camshaft reference, but this is not should be understood restrictive.
- the deburring tool In order to decouple the movements of the deburring tool, which oscillates together with the shaft in the axial direction is moved from the processing element in a simple manner realize, the deburring tool is on an axis parallel to Wave slidable slide attached. This sled performs the same movements as the wave and is in Tool holder slidably mounted.
- the Tool holders can mutually each other attack opposite to the shaft.
- the Machining element a grinding wheel, a finish element, e.g. a finishing stone or a finishing tape in particular with a contact shoe, his.
- the burr already be removed when grinding the bearings or a degree caused by the grinding can occur during subsequent machining process, that is, when finishing be removed from the storage.
- the deburring tool at least one radially to the shaft having aligned deburring, the at the front side abuts the shaft portion to be deburred.
- This Entgratfinger is at the radial approach of the tool the bearing also radial to be deburred Moved shaft section so that it at the front, from which the ridge protrudes, comes to rest. Will the wave set in rotation, then at the same time the bearing machined and the deburring finger is over the front of the Striped to be deburred shaft section. The ridge becomes thereby canceled.
- this deposit usually between two Cam is provided is at a preferred Embodiment on both sides of the processing element respectively provided at least one deburring tool. In this way can edit two storage locations simultaneously Deburring cam or sealing seats. It is also conceivable that all lugs and collars are deburred simultaneously.
- a camshaft is usually two Having provided at their ends sealing seats over which the Camshaft by means of two shaft seals to the outside is sealed.
- a processing element designed as a finish element provided that the machining element and the Deburring tool in the axial direction next to each other.
- the direction of rotation can change the machining element by an angle of be arranged offset up to 90 ° to the deburring tool.
- the tool holder In the tool holder according to the invention is at least one Deburring tool carrying carriage slidably mounted. This slide is guided on guide thorns and by a Pressurized spring so that it is against the force of Spring can be moved out of its rest position.
- FIG. 1 shows a total of 10 Processing pliers with two to each pivot bearing 12 or 14 pivotally mounted pivoting arms 16 and 18, at their free ends are each provided with a tool 20, and between them include a shaft 22 to be machined.
- the two pivot arms 16 and 18 are pressurized, so that processing shoes 24 a finishing belt 26 with a predetermined pressure on a bearing to be machined bearing 28 of Press shaft 22.
- the Finishing tape 26 is the Finishing tape 26, as is well known, by a predetermined Distance traveled in the direction of arrow 30 on.
- the tool 20 has, as seen in Figure 2, a Tool holder 32, attached to the free end of each Swivel arm 16 and 18 is screwed by means of screws 34.
- the machining shoe 24 which e.g. made of Vulkollan, directly on the tool holder 32 set and thus on the pivot arms 16 and 18 in Axial direction of the shaft 22 fixed.
- the processing bowl can also be made of steel.
- FIG. 3 which shows a front view of the tool 20, leaves next to the processing shoe 24 each two as Deburring fingers 42 detect deburring tools 43 formed, wherein each Entgratfinger 42 on a separate slide 44th is attached.
- the slides 44 are in turn of the Guiding mandrels 38 penetrated so that they to this are stored displaceably.
- This means that the carriages 44 are pressurized in this way, that the outer slide 44 axially outward and the two inner carriage 44 axially inwardly, that is in the direction of the machining shoe 24 against the force of the compression springs 50 can be moved.
- the Entgratfinger 42 each apart.
- FIG. 5 shows a section of the shaft 22, which with two bearings 28 is provided, to each of which a Finishing belt 26 is applied and from a processing shoe 24th is pressed.
- each two cams 52 and 54 Located on both sides of the bearings 28 each two cams 52 and 54, at the end faces 56th and 58 each one of the Entgratfinger 42 abuts.
- the Entgratfinger 42 a distance from each other which is smaller than the width of the cams 52 and 54, so that when sliding the Entgratfinger 42 on the cam 52nd and 54 these are pushed apart by the sledges 44 on the guide pins 38 against the force of the springs 50th be moved.
- the sliding of the deburring fingers 42 is facilitated by the deburring fingers 42 at their free Ends have an inlet slope 60.
- each machining shoe 24 a Support member 70 is radially opposite, which also a shoe 68 and with the also the finishing tape 26 to the opposite side of the bearing 28th is pressed, whereby the pressure forces of the pivot arms 16 and 18 are supported.
- the tool 20 according to the invention can also without Finish machining so used only for deburring become.
