Abstract
Description
- This specification relates to a power tool for setting fasteners.
- Some existing blind rivet setting tools have a ball screw mechanism driven by an electric motor for causing movement of a set of jaws in order to pull the mandrel of a rivet. Such a tool is described in
EP3530372A2 for example, wherein the motor is located above the handle. In order for the tool to feel balanced in a user's hand the manufacturer needs to carefully consider the arrangement of features within the housing relative to the handle. Having the motor and all transmission features above the handle makes the tool top heavy. Also due to space limitations within the housing there is some play off between arranging internal features of the tool such that the tool works vs. arranging such features so that weight distribution of the tool is optimised. - According to an aspect of the present invention there is provided a power tool comprising: a motor at least partially located within the handle of the tool and having a motor output shaft extending along a first axis extending along the length of the handle; and a fastener gripping portion operatively coupled to the motor via a transmission which in use causes movement of the fastener gripping portion along a second axis, perpendicular to the first axis, between a home position and a retracted position to set a fastener engaged by the fastener gripping portion; the transmission comprising a bevel gear arrangement for redirecting torque flowing along the first axis in use which is input to the bevel gear arrangement so that torque output from the bevel gear arrangement flows along the second axis and wherein the transmission further comprises a mechanism for converting torque output from the bevel gear arrangement in use into a linear force for causing linear movement of the fastener gripping portion.
- The mechanism may be a ball screw mechanism extending along the second axis between the bevel gear arrangement and the fastener gripping portion. Alternatively the mechanism may be a roller screw mechanism extending along the second axis between the bevel gear arrangement and the fastener gripping portion.
- The motor may be located entirely within the handle.
- The transmission may comprise at least one planetary gear stage for transferring torque from the motor along the first axis in use.
- The at least one planetary gear stage may be at least partially located within the handle, optionally entirely located within the handle.
- The power tool may comprise a battery attachment portion on the handle such that a notional line extending between the battery attachment portion and the motor output shaft extends along the first axis.
- The motor may be a brushless DC motor.
- The fastener gripping portion may be a jaw assembly.
- The power tool may be a blind rivet setting tool.
- Various aspects and embodiments of the invention will now be described by way of nonlimiting example with reference to the accompanying drawings, in which:
-
Fig. 1 shows a side cross-sectional view of a blind rivet setting tool; -
Fig. 2 shows a close-up of part of the blind rivet setting tool inFig. 1 ; and -
Figs 3a and 3b show a jaw assembly of the blind rivet setting tool inFig. 1 in first and second configurations respectively. -
Fig. 1 shows a side cross-sectional view of a blindrivet setting tool 100. Thetool 100 has ahousing 102 of a clam shell type construction having two halves which are fastened together. Abattery 104 is releasably connected to thebase 122 of thehandle 106 via a battery attachment feature. To use the tool 100 a user inserts the mandrel of a blind rivet into anose 108 of thetool 100 and pulls atrigger 110. In response to acontroller 112 of the tool determining that thetrigger 110 has been pulled thecontroller 112 generates a signal to activate amotor 114, which is a DC brushless motor. Themotor 114 is located in thehandle 106 and has amotor output shaft 116. Torque from themotor output shaft 116 is transferred via atransmission 118 to afirst bevel gear 120. Thetransmission 118 comprises at least one planetary gear arrangement for reducing output speed while increasing torque. Thefirst bevel gear 120 rotates at a lower speed than themotor output shaft 116 however with an increased torque relative to themotor output shaft 116. Themotor output shaft 116,transmission 118 andfirst bevel gear 120 are aligned along a first axis A-A which extends along a longitudinal length of thehandle 106. By also locating thebattery 104 on the first longitudinal axis A-A weight distribution of thetool 100 is improved. - It will be appreciated that there is some design freedom in the
transmission 118 between themotor output shaft 116 and thefirst bevel gear 120. In particular the number of planetary gear stages, and its (or their) configuration, forming thetranmission 118 depends on the required gear ratio to be achieved between themotor output shaft 116 and thefirst bevel gear 120. Given that it is well known that planetary gear stages step down rotation speed while stepping up torque persons skilled in the art, based on the disclosure given herein, will be able to decide upon a suitable transmission arrangement which achives the required gear ratio for thier tool to function; wherein the appropriate gear ratio depends on multiple factors including maximum achieveble motor output torque, pitch of theball screw arrangement 130 described below, friction between moveable featiures within thetool 100 and the maximum pull force required to set a fastener. It will be appreciated that for some tools 100 asuitable transmisison 118 may only have a single planetary gear stage, whereas for other tools asuitable transmisison 118 may have a plurality of planetary gear stages arranged in series. - Continuing with reference to
Fig. 1 asecond bevel gear 124 is provided on the end face of adriving sleeve 126. Thedriving sleeve 126 is rotationally fixed relative to aninput sleeve 128 of aball screw arrangement 130. Thedriving sleeve 126 andinput sleeve 128 are fixed relative to each other due to a friction fit arrangement. An internal surface of theinput sleeve 128 comprises a threaded surface. The outer surface of the drivingsleeve 126 is supported bybearings 132 which enable rotation of thedriving sleeve 126 with respect to thehousing 102. A threadedrod 134 is mounted within theinput sleeve 128, which extends through theinput sleeve 128. A plurality of balls, such as metal ball bearings, ride in the opposing threaded surfaces of theinput sleeve 128 and threadedrod 134, thereby defining aball screw arrangement 130. - When the
input sleeve 128 is rotatably driven by thedriving sleeve 126 this causes axial movement of the threadedrod 134. In other words, torque from themotor 114 is transferred through thetransmission 118, first andsecond bevel gears sleeve 126 to theinput sleeve 128, whereby rotation thereof causes axial movement of the threadedrod 134. The threadedrod 134 is configured to move along a second longitudinal axis B-B of thetool 100. The threadedrod 134 can move forwards or backwards along the axis B-B depending on the motor driving direction. - Referring to
Fig. 2 a connectingsleeve 300 is attached to afirst end 302 of the threadedrod 134, which is mounted to the threadedrod 134 via a screw thread. A pull-back hull 304 is threadably attached to the connectingsleeve 300. Axial movement of the threadedrod 134 along the second longitudinal axis B-B therefore also causes axial movement of the pull-back hull 304. - A
jaw assembly 500 is located within the pull-back hull 304. The jaw assembly (shown inFig. 3a ) has a plurality of circumferentially arrangedjaws 306 each of which has a rampedouter surface 308 for cooperating with a conicalinner surface 310 of the pull-back hull 304. Aseparator sleeve 312 is forced by aspring 314 against thejaws 306; more specifically a rampedfront surface 316 of theseparator sleeve 312 is forced against rampedrear surfaces 318 of thejaws 306. Anosepiece 320 is releasably attached at the opening to thenose 108 of thetool 100 which has an annular rampedsurface 402. Each of thejaws 306 have a front rampedsurface 400 for cooperating with the annular rampedsurface 402 of thenose piece 320. Cooperation between the rampedouter surfaces 308 of thejaws 306 and the conicalinner surface 310 of the pull-back hull 304, between the rampedrear surfaces 318 of thejaws 306 and the rampedfront surface 316 of theseparator sleeve 312 and between the front rampedsurfaces 400 of the jaws and the annular rampedsurface 402 of thenose piece 320 enables thetool 100 to set blind rivets in use. - To set a blind rivet, while the
jaw assembly 500 is in a home position a mandrel of the blind rivet is inserted through thenose piece 320 such that the mandrel extends between thejaws 306, thereby urging thejaws 306 radially apart (seeFig. 3b ). Upon pulling thetrigger 110 of thetool 100 thecontroller 112 receives output from a trigger sensor and in response activates themotor 114 for causing the threadedrod 134, and thus the pull-back hull 304, to move along the second longitudinal axis B-B to the right inFigs. 1 and2 . As the pull-back hull 304 is retracted its conicalinner surface 310 is forced against theouter surfaces 308 of thejaws 306, whereby a component of force draws thejaws 306 backwards with the pull-back hull 304 away from the home position whereas another component of force urges thejaws 306 radially inwards thereby clamping the mandrel of the blind rivet being set between thejaws 306. - In other words pulling the pull-
back hull 304 to the right inFigs. 1 and2 causes thejaws 306 to grip and pull the mandrel of a rivet being set. The blind rivet thus is pulled against thenose piece 320 for deforming the blind rivet and when the mandrel of the blind rivet is pulled far enough for setting the blind rivet the mandrel snaps. - Designers are free to select a suitable way for the
controller 112 to control operation of themotor 114 in use to implement a fastening operation. In other words designers are free to select a suitable way for thecontroller 112 to determine when thejaw assembly 500 has been retracted far enough during a fastener setting stage of operation at which point in time retraction of thejaw assembly 500 is ceased. For example a mechanical switch may be provided within thetool 100 and in response to thecontroller 112 determining that thetrigger 110 has been pulled by a user thecontroller 112 causes the pull-back hull 304 (and thus the jaw assembly 500) to be retracted until a feature of the pull-back hull 304 actuates the mechanical swich thereby generating output indicative that thejaw assembly 500 has been pulled back sufficiently far to set a blind rivet. Alternatively an optical sensor may be provided within thetool 100 which generates output based on the presence or absence of a feature on the pull-back hull 304 wherein based on output from the optical sensor thecontroller 112 can determine that the pull-back hull 304 (and thus the jaw assembly 500) has reached a predetermined retracted position for setting a blind rivet. Alternatively thecontroller 112 may be configured to monitor the magnitude of current drawn from thebattery 104 during a fastening operation and when the current draw drops by at least a predetermined extent during a fastening stage of operation thecontroller 112 can determine that the mandrel of the blind rivet being fastened has snapped and thus that thejaw assembly 500 has been pulled back sufficiently far. - Subsequently to the fastening stage of operation the
tool 100 is required to perform a reset operation to dispose of the broken mandrel and to accept a fresh blind rivet for setting. During a reset operation of thetool 100 thecontroller 112 causes themotor 114 to reverse its direction for moving the threadedrod 134, and thus the pull-back hull 304, in the other direction along the second longitudinal axis B-B to the left inFigs. 1 and2 . When the pull-back hull 304 has been moved sufficiently far to the left thespring 314 via theseparator sleeve 312 will urge the front rampedsurfaces 400 of thejaws 306 against the annular rampedsurface 402 of thenose piece 320. Further movement of the threadedrod 134 to the left inFigs. 1 and2 will increase the pressure of thespring 314 against theseparator sleeve 312 and thus cause the front rampedsurfaces 400 of thejaws 306 to ride along the annular rampedsurface 402 of thenose piece 320 while the rampedrear surfaces 318 of thejaws 306 ride along the rampedfront surface 316 of theseparator sleeve 312. This causes thejaws 306 to move radially outwards and release the grip on the snapped mandrel, whereby with reference toFig. 1 the released snapped mandrel can be caused to fall under gravity along aninternal path 204 in the direction of acollection chamber 200. For example, after a rivet setting operation, when thejaw assembly 500 has been returned to the home position, the user tilts thetool 100 such that the snapped mandrel moves into thecollection chamber 200. Theinternal path 204 is defined by aligned openings extending through components between thejaws 306 and thecollection chamber 200, including afirst channel 202 extending through the threadedrod 134 along the second longitudinal axis B-B and asecond channel 204 through aguidance sleeve 206. - Designers are free to select a suitable way for the
controller 112 to control operation of themotor 114 in use to implement a reset operation. In other words designers are free to select a suitable way for thecontroller 112 to determine when thejaw assembly 500 has returned to the home position at which point in time reverse movement of thejaw assembly 500 is ceased. For example a mechanical switch may be provided within thetool 100 and in response to thecontroller 112 determining that thetrigger 110 has been released by a user thecontroller 112 causes the pull-back hull 304 (and thus the jaw assembly 500) to be moved in the reverse direction until a feature of the pull-back hull 304 actuates the mechanical swich thereby generating output indicative that thejaw assembly 500 has returned to the home position. Alternatively an optical sensor may be provided within thetool 100 which generates output based on the presence or absence of a feature on the pull-back hull 304 wherein based on output from the optical sensor thecontroller 112 can determine that the pull-back hull 304 (and thus the jaw assembly 500) has reached the home position. Alternatively a magnet is provided on the pull-back hull 304 and a Hall sensor is provided in a fixed location within the tool, wherein such features can be arranged such that upon the Hall sensor generating a suitable output based on interacting with the magnet on the pull-back hull 304 thecontroller 112 can determine that the pull-back hull 304 (and thus the jaw assembly 500) has reached the home position. - Turning to
Figs 3a and 3b thejaw assembly 500 will now be discussed in more detail.Fig. 3a shows a perspective view of thejaw assembly 500 in a first configuration in which thejaws 306 are located radially as close to each other as possible.Fig. 3b shows a perspective view of thejaw assembly 500 in a second configuration in which thejaws 306 are urged radially apart from each other such as by a mandrel of a blind rivet being inserted through the space between thejaws 306 or thejaws 306 being forced against the annular rampedsurface 402 of thenose piece 320. Thejaw assembly 500 comprises threeidentical jaws 306 circumferentially arranged about a jaw assembly axis G-G. When thejaw assembly 500 is mounted in thetool 100, the jaw assembly axis G-G is coaxial with the second longitudinal axis B-B of thetool 100. The threejaws 306 can move radially with respect to the jaw assembly axis G-G. - There are situations during which the
jaw assembly 500 is removed from the tool, in particular during routine maintenance of thetool 100 during which it is disassembled and then reassembled after being cleaned. Alternatively thejaw assembly 500 may be swapped with a new jaw assembly because thejaws 306 of the original jaw assembly have worn. Further alternatively thejaw assembly 500 may be swapped with a new jaw assembly because the different jaw assemblies are configured for use with different sized mandrels. Referring again toFigs. 3a and 3b the jaw assembly has a flexible o-ring 502 for holding thejaws 306 of thejaw assembly 500 together when it is not located within thetool 100. Each of thejaws 306 defines part of anannual groove 504 when thejaws 306 are in the configuration shown inFig. 3a wherein the o-ring 502 is located in theannular groove 504 and biases thejaws 306 together. The o-ring 502 can be made from an elastic material such as rubber. - In view of the foregoing it will be appreciated that by locating the
motor 114, thetransmission 118 and thebattery 104 on the same axis A-A extending along the length of thehandle 106 improves weight distribution of internal features of thetool 100. Also by providing themotor 114 within thehandle 106 leaves more space available within the tool housing above the handle, whereby there is more freedom to position features of the tool in positions which improve weight distribution of internal features of the tool. - By providing the
motor 114 only partially within thehandle 106 achieves the abovementioned advantages to a lesser extent. By providing themotor 114 and also at least part of thetransmission 118 within thehandle 106 achieves the abovementioned advantages to a greater extent. - It will be appreciated that whilst various aspects and embodiments have heretofore been described the scope of the present invention is not limited thereto and instead extends to encompass all arrangements, and modifications and alterations thereto, which fall within the spirit and scope of the appended claims.
- In some embodiments the
motor 114 is only partially received within thehandle 114. - In some embodiments at least one planetary gear stage of the
transmission 118 is received in thehandle 106. - In some embodiments the
motor 114 and thetransmission 118 are received in thehandle 106. - In some examples the
battery 104 is removable from thetool 100 or alternatively thebattery 104 is integral to thetool 100. Alternatively or additionally thetool 100 may comprise other power sources e.g. it may be configured to receive power from a mains power supply. - As shown in
Fig. 1 , the drivingsleeve 126 andinput sleeve 128 are fixed to each other due to a friction fit arrangement. Alternatively the drivingsleeve 126 andinput sleeve 128 can be fixed via an interlocking arrangement such as a spline fit arrangement or other male and female interlocking-type arrangement. - As shown in
Fig. 3a , the o-ring 502 is seated in agroove 504. In some alternative examples the o-ring 502 may be replaced with any suitable means to keep thejaws 306 together such as a c-clip, a circlip, an e clip, a snap ring, or another spring fastener. - The o-
ring 502 is made from an elastic material such as rubber. In other examples, the o-ring 502 is optionally made from polyurethane, PTFE, ethylene propylene rubber, neoprene, nitrile, or silicone. - As shown in
Fig. 3a thejaw assembly 500 comprises threejaws 306. However, in alternative examples, thejaw assembly 500 can comprise any number ofjaws 306 more than two. - In some examples the
jaws 306 do not interlock with each other for maintaining jaw alignment. - In some embodiments the
tool 100 can be configured to detect the occurrence of a mandrel snapping by monitoring motor speed. During a pull back stage of operation as thejaw assembly 500 pulls the mandrel of a rivet more tightly the speed of themotor 114 will decrease and then suddenly increase when the mandrel snaps. Thecontroller 112 can monitor for such a sudden increase in motor speed and in response to detecting such occurrence determine that the mandrel of the rivet being set has snapped and in response cease retracting thejaw assembly 500. Subsequently thecontroller 112 initiates the reset stage of operation either automatically or in response to release of thetrigger 110. - The
motor 114 has been described as being a brushless motor and thecontroller 112 cooperates with the brushless motor (in particular with its control electronics) in order to control the brushless motor. In other embodiments however themotor 114 may be a brushed motor having a motor output shaft driven by a stator and having at least one magnet on the motor output shaft. It is here mentioned that in battery operated embodiments themotor 114 is configured to operate using DC current, whereas in mains operated embodiments the motor is configured to operate using AC current. - In some embodiments the
tool 100 may have a roller screw mechanism instead of aball screw arrangement 300 for transferring rotational motion into linear motion. A person skilled in the art will appreciate that this can be achieved by rotationally fixing the drivingsleeve 126 to an input sleeve of the roller screw mechanism; wherein a set of rollers are provided between the internal surface of the input sleeve and an external surface of the threadedrod 134. When the drivingsleeve 126 is caused to rotate it drives rotation of the input sleeve of the roller screw mechanism and thus via the rollers causes linear movement of the threadedrod 134 and thus the jaw assembly. - Finally the heretofore described functionality need not necessarily be used exclusively in blind rivet setting tools but may be used in other power tools having a fastener gripping portion which moves backwards from a home position in order to set a fastener and which is then returned to the home position. For example the heretofore described functionality can be implemented in other tools such as rivet setting tools (not necessarily blind rivet fastening tools), swage fastener tools and lockbolt fastener tools wherein the fastener gripping portion of such tools is configured to grip the type of fastener which the tool is used to set e.g. the fastener gripping portion of a swage fastener tool is configured to grip a swage fastener.
