Definitions
- the invention relates to a device for screwing in and setting self-drilling blind rivets with at least one clamping jaw that holds an inserted pulling die and holds it positively or non-positively.
- Such a device is known for example from EP-A-0 213 101.
- a receiving part which has a frustoconical recess at its front end
- two clamping jaws are arranged diametrically opposite one another.
- These clamping jaws also have a conical section-like surface on their outer boundary, so that an inserted mandrel can be gripped and held by axially pressing the clamping jaws into the receiving part.
- there are problems for proper rotational driving since a partial and not necessarily uniform angular displacement of the two clamping jaws can take place as a result of the torque that occurs.
- the object of the invention is therefore to create a device of the type mentioned at the beginning in which there is an exact securing of the position of the clamping jaws and with which an optimal transmission of the necessary torque to the mandrel of a blind blind rivet to be screwed in and set is possible is.
- the clamping jaw (s) be plate-shaped and be or are guided in a receiving part in a groove (s) open radially to its central axis, the bottom of the groove and the associated boundary surface of a clamping jaw being at the same acute angle Central axis of the recording partly tapering towards the free end thereof, and that the receiving part is held axially displaceably in a housing which is at least secure against rotation during the setting process.
- the clamping jaws are optimally secured in the direction of rotation, since they are supported on both sides on guide surfaces, that is to say on the lateral boundary surfaces of a radially extending groove. Therefore, it is always guaranteed that the clamping jaws act concretely in the direction of the central axis of the receiving part. Optimal rotational driving of an inserted pulling mandrel of a blind blind rivet is thus always guaranteed and no problems arise for the force absorption in the direction of rotation.
- the manufacture of the clamping jaws is very simple due to the platelet-shaped design, with precise machining by punching and milling processes being possible. There is therefore also a substantially larger selection of materials, with which it can be avoided that individual sections of the clamping jaws have a brittle material structure, which can occur, in particular, during manufacture by means of a pressing process.
- both the receiving part and the clamping jaw (s) in the housing are assigned a displacement limitation, the displacement path of the receiving part towards the free end of the housing being longer than the displacement path of the clamping jaw (n ) in this direction.
- a triggering possibility for the clamping jaws pressed in the radial direction has therefore been created in a simple manner.
- the clamping jaws are released only by an axial further movement of the receiving part, so that the section of the dome which is still held in place is released after the blind rivet has been set.
- the clamping bracket (s) has a radially outwardly projecting tab at its rear end and this tab engages in a longitudinal slot in the housing, the end of the longitudinal slot facing the free end of the housing as Displacement limit for the tab of the clamping jaw (s) is implemented.
- This tab which projects freely on the clamping jaws, therefore forms a simple design in order to limit the displacement of the clamping jaws.
- this tab represents a further possibility of connecting the receiving part and the housing to one another when viewed in the direction of rotation. It is also of particular advantage that it is precisely this tab, but also the special mounting of the clamping jaws in the grooves of the receiving part, which makes it easy to replace the clamping jaws.
- the clamping jaws can be pulled out of the device without dismantling the entire device by grasping the tab. It is therefore possible in a simple manner to remove and reinsert the clamping jaws via the longitudinal slot provided in the housing.
- two diametrically opposed grooves are provided in the receiving part and, accordingly, two clamping jaws. It has already been shown in experiments that two alone can metrically opposed clamping jaws of the type according to the invention are sufficient to ensure proper rotational driving and proper gripping of the pulling mandrel during the setting process.
- the boundary surface of the clamping jaw (s) facing the central axis of the receiving part runs parallel to the latter.
- the limiting surface of the clamping jaw (s) facing the central axis of the receiving part has a surface corresponding to the surface design of a tension mandrel to be used having.
- the boundary surface of the clamping jaw (s) facing the central axis of the receiving part is provided with transverse ribs, depressions, knobs or knurling.
- the receiving part is already held in the housing in a torsion-proof manner by the projecting tab of the clamping jaws, it is advantageous if further measures contribute to this. It is therefore provided that the receiving part engages in longitudinal slots of the housing with radially projecting bolts. This is probably an axial displacement between the receiving part and the housing, but at the same time also ensures a backup in the direction of rotation.
- a special constructive design of such an embodiment provides that the projecting bolts penetrate longitudinal slots on the housing and on the receiving part which is tubular over part of its length and start from a supporting part which is axially displaceable in the middle of the receiving part. The bolts therefore engage both in the longitudinal slots of the housing and in the receiving part and lock these two parts in the direction of rotation. In addition, there is the possibility of deriving further functions from the supporting part of the bolt.
- the support part is designed to be spring-loaded in the direction of the clamping jaws and on which the region of the clamping jaws projecting beyond the grooves in the axial direction is supported.
- the clamping jaws can therefore be designed to be constantly spring-loaded in the clamping direction in a simple manner, this spring force in no way preventing the insertion of the pulling mandrel into the device. This measure ensures that the clamping jaws are always held in their corresponding position in the receiving part and thus also in a captive manner.
- this supporting part has to be raised by grasping the radially projecting bolts against the force of the spring, so that the clamping jaws are exposed. The clamping jaws can then be gripped and removed on their projecting tab.
- the support part can also take on further functions, namely when the spring-loaded pin is guided in the support body and is designed to be spring-loaded separately from it. It is therefore possible in a simple construction to properly hold the pin which engages between the clamping jaws and causes the separated mandrel to be ejected and is designed to be spring-loaded.
- the entire construction of the device is very simple and can also be coupled to a drive in a simple manner. It is therefore advantageously provided that a shaft which can be coupled to a drive or a pulling device is inserted at the end of the receiving part which faces away from the free end.
- the grooves open towards the central axis of the receiving part open into a central, axially identical bore.
- two work steps are then required. required, namely on the one hand the production of the bore and on the other hand the production of the grooves in one milling process.
- the special design of the clamping jaws and the grooves provided for guiding the same have made it possible to produce the holders for the clamping jaws to be used in one operation.
- two grooves lying opposite one another in one plane in the receiving part merge directly into one another and thus form a single, wedge-shaped recess symmetrically to the central axis of the receiving part.
- Such a groove can be produced in a simple manner by a milling tool, and it is therefore also ensured that the mandrel cannot engage laterally next to the facing surfaces of the clamping jaws.
- the tension mandrel is thus always inserted between the mutually facing boundary surfaces of the clamping jaws, which also extend over the entire width of the groove.
- the groove base and the associated delimiting surface of the clamping jaw have an arcuate cross section.
- Such a configuration is only possible if grooves are formed, since the arc shape or the radius of the boundary surfaces is constant over the entire length of the groove base or over the entire length of the associated boundary surface of the clamping jaw.
- the end cap provided at the free end of the housing has a through opening for inserting a pulling mandrel, radially spring-loaded holding means being provided in the area of the through opening. This additional measure ensures that a pull-blind rivet inserted into the device is also held captively in the device until the drilling process or until the setting process.
- FIG. 1 shows a device in a longitudinal section with a blind rivet assigned in the insertion position
- FIG. 3 shows a section along the line III-III in FIG. 2;
- Fig. 4 shows a longitudinal section through the device in a position after completion of the setting process of the blind rivet.
- the device 1 for screwing in and setting self-drilling blind rivets 2 consists essentially of clamping jaws 3, a receiving part 4 and a housing 5.
- the clamping jaws 3 are plate-shaped and guided in the receiving part 4 in grooves 7 which are open radially to the central axis 6 thereof.
- the groove base 8 and the associated boundary surface 9 of a clamping jaw 3 run at the same acute angle to the central axis 6 and taper in the direction of the free end thereof.
- a displacement limitation is provided in the housing 5 both for the receiving part 4 and for the clamping jaws 3, the displacement path of the receiving part 4 in the direction towards the free end of the housing 5 being longer than the displacement away of the jaws 3 in this direction.
- An end cap 10 is provided at the free end of the housing 5 as a displacement limitation for the receiving part 4.
- the inner surface 1 of this end cap 10 forms a stop as a displacement limitation for the receiving part 4 in the direction of the free end of the housing 5.
- the jaws 3 have at their rear end a radially outwardly projecting tab 12 which engages in a longitudinal slot 13 in the housing 5.
- the end 14 of this longitudinal slot 13 facing the free end of the housing 5 is designed as a displacement limitation for the tab 12 of the clamping jaws 3. So if the tab 12 of the jaws 3 comes to rest at the end 14 of the longitudinal slot 13, the receiving part 4 can be moved further towards the end cap 10 without the jaws 3 being able to follow. As a result, the clamping jaws 3 in the clamping position can be released in a simple manner.
- the construction shown provides two diametrically opposed grooves 7 in the receiving part 4 and correspondingly two clamping jaws 3.
- the boundary surfaces 15 of the clamping jaws 3 facing the central axis 6 of the receiving part 4 run parallel to the central axis 6 and thus also parallel to one another. It is therefore possible to clamp the entire length of the mandrel with a constant force.
- the boundary surfaces 15 can, however, additionally have a surface corresponding to the surface design of a pulling mandrel 16 to be used, in order thereby to improve the holding effect precisely during the pulling process. It would be conceivable to provide these boundary surfaces 15 with transverse ribs, depressions, knobs or knurling.
- the grooves 7 open towards the central axis of the receiving part 4 open into a central bore 17 with the same axis.
- the two it would also be possible for the two to lie opposite one another in one plane
- Grooves 7 in the receiving part 4 merge directly into one another and thus form a single, wedge-shaped recess lying symmetrically to the central axis of the receiving part 4. All that then remains between the mutually facing boundary surfaces 15 of the clamping jaws 3 is a corresponding opening into which the mandrel 16 of the blind rivet 2 to be inserted can be inserted. This also ensures that the mandrel is held securely since it cannot deflect laterally next to the clamping jaws 3.
- a pin 18 engages between the clamping jaws 3, which is directed radially to the central axis 6 of the receiving part 4, and which can be displaced axially and is spring-loaded.
- This pin 18 is slidably held in a support body 19 and pressed by a spring 20 into its operating position.
- the pin 18 causes the torn mandrel 16 to be ejected from the device.
- the pin 18 is pressed further into the device against the force of the spring 20 (see FIG. 2), so that after the clamping jaws 3 are released and thus after the pulling mandrel 1 6 has been released, they spring back due to the spring-loaded action Pen 18 is ejected.
- the receiving part 4 is in the housing 5 rotatably.
- bolts 21 are provided which engage in the longitudinal slots 13 on the housing 5.
- the projecting bolts 21 penetrate both the longitudinal slots 13 in the housing 5 and the longitudinal slots 22 in the receiving part 4 which is tubular over part of its length.
- This support part 19 is loaded by a spring 23, so that the support part 19 is supported on the area of the clamping jaws 3 projecting beyond the grooves 7 in the axial direction.
- the support member 19 thus causes d ⁇ e jaws 3 are always in their proper operating position and are held captive in the device.
- the supporting part 19 can be pulled in a simple manner by gripping the bolts 21 against the rear end of the device 1, whereupon the clamping jaws 3 can be gripped on the tab 12 and pulled out through the longitudinal slots 13 .
- the insertion of new jaws is also possible in the same simple way.
- the end cap 10 provided at the free end of the housing 5 has a through opening 24 for inserting a pulling mandrel 16 of the blind rivet 2.
- radially spring-loaded holding means are provided in the area of the through opening 24 of the end cap 10. These holding means can be carried out in various ways, e.g. by means of resilient pins or spring parts or spring-loaded balls etc. inserted into bores opening radially into the through opening 24,
- a shaft 25 is inserted at the free end of the receiving part 4.
- This shaft 25 and the housing 5 can be coupled with a corresponding drive device, which on the one hand causes the turning process when drilling the hole and on the other hand the pulling process when the rivet is set.
- the device according to the invention is thus a type of attachment for a riveting device, This attachment can be used to hold an inserted rivet mandrel of a blind rivet correctly and correctly during the drilling process and also during the setting process.
