17 Claims.
This invention relates to a device for setting hollow rivets.
Where it is desired to rivet two pieces of material together it is not always possible to have access to both sides of the work. Under Such conditions it is usual to apply a hollow rivet in the following manner: A hole sufficiently large to receive a rivet is punched or drilled in the two pieces of material to be secured together. A hollow rivet having a ange thereon is mounted on the shank of a headed mandrel. The head of the mandrel and the rivet are inserted in the hole provided, the rivet is held in place by pressure applied to the flange thereof and the mandrel is drawn through the rivet to deform and spread the end thereof opposite the flange. The broad object of this invention is to provide a tool or machine to hold a rivet in position and draw a headed mandrel therethrough.
Depending upon the size of the rivet, considerable force may be necessary lto d raw the mandrel through the rivet. It is not desirable to use manual means for this purpose. Therefore, a further object of this invention is to provide a motor driven means to draw the headed mandrel through the rivet. To this end, a further specic object of the invention is to provide a driving worm and a worm wheel with eccentrics thereon to reciprocate a mandrel holding, means.
Where a power driven, reciprocating mandrel holding means is used it is desirable to stop the operation of the mandrel holding means at the top of its. stroke. If the mandrel were again forced through the rivet after it has once been withdrawn, it might cause damage to the rivet. It is also desirable that the operator know when the mandrel has been entirely withdrawn through the rivet, so that the tool will not be removed from the rivet until the mandrel is entirely removed. Therefore, a further object of the invention is to provide means to automatically stop the motion of the mandrel holding device when the mandrel has been entirely drawn through the rivet and at the same time indicate to the operator that the operation is complete. v
When the mandrel is drawn through the rivet the head of the mandrel is deformed so that a new mandrel is used for each operation. Accordingly, it is desirable to provide a mandrel holding means which will permit the easy removal and insertion 'of mandrels. Therefore, a specific object of the invention is to provide a mandrel holding chuck which. will hold the mandrel rmly in place while the mandrel is drawn through the rivet, but lwhich will not bind the,
mandrel so that it may be quickly removed and another mandrel substituted.
A further object of the invention is to provide a simple, inexpensive device, easy and positive vof operation but fast in action.
The invention consists of the construction, combination and arrangement of parts as herein illustrated, described and claimed.
In the accompanying drawings, forming part hereof, is illustrated one form of embodiment of the invention, in which drawings similar reference characters designate corresponding parts, and. in which:
Figure 1 is a vertical section, the driving means being in elevation, showing the position of the parts at the beginning of the riveting operation;
Figure 2 is a vertical section, partly in elevation, showing the position of the parts at the conclusion of the riveting operation;
Figure 3 is a horizontal section taken approxi- 0 mately on line 3-3 of Figure 2, looking in the direction indicated by the arrows;
Figure 4 is a horizontal section taken approximately on line 4 4 of Figure 2, looking in the direction indicated by the arroyvs;
Figure 5 is an enlarged vertical section taken approximately on line 5--5 of Figure 1, looking in the direction indicated by the arrows;`
Figure 6 is an enlarged front elevation of the mandrel holding chuck; and, 3
Figure 7 is a front elevation of the chuck shown in Figure 6, together with its -associated parts.
Referring to the drawings, 8 designates a cylindrical housing to which is joined a substantially rectangular open-sided housing 9. The housings or casings 8 and 9 contain all of the operative parts of the device with the exception of the motor driving means. The lower end of the housing 8 is tapered as shown at I0 and termi- 40 nates in a squared nose II. The nose II is provided With a bore I2 to receive the shank of a mandrel A having a tapered head B. A hollow rivet C is carried on the mandrel A and is provided with a flange D adapted to abut the nose I I, and to lie against one of the plates E which are to be joined together as shown in Figure 2.
Disposed in the housing 8 is a chuck bo'dy I3 having a bore I4 to receive the shank of Ythe' mandrel A. The bore I4 registers with the bore 50 y I2. As 56st shown in Figures 6 and 7 the chuck body I3 is provided with a plurality of slots I5 formed at an angle to the bore I4. The lower ends ofthe slots I5 merge with the bore I 4. and gripping rolls I6 are disposed in the slots I5. 55
The rolls I6 are adapted to bear against the mandrel A to hold the mandrel rmly in position. As shown in Figure 6 longitudinal pressure downwardly on the mandrel A, or, converse- 5 ly, upward movement of the chuck I3 against the resistance of the mandrel A, will cause the rolls I6 to grip the mandrel A more firmly and hold it in place.
The'ends of the gripping rolls' I9 are reduced as shown at I1, and are carried in horizontal slots I9 in control plates I9. The control plates I9 are slidable on the chuck body I3 in recesses 29 which form guideways for the plates I9. A forked leverv 2| is provided to move the control plates `I9 and has an extension 22 which projects through a slot 23 in the housing 9. A holev 24 is provided lin the chuck bodyI3 through which is disposed a pivot 2l to hold the lever 2| to the chuck body I3. The lever 2I is secured to the plates I9 by means of a pivot 29. An 4opening 21 is provided through the chuck body I3 to permit movement of the pivot 29. A recess 29 is formed in the chuck body I3 to receive the transverse portion lof the lever 2i and also to receive a spring 29 to exert downward pressure on the lever 2 I. The pressure of the spring 29 forces the plates I9 downward. The rolls I9 are carried downward by the slots lI9 in the plates I9, and therefore caused to bear against the mandrel A to hold it nrmly in place.
The chuck I3` is moved in the casing 9 by means of straps 39 which are Aconnected to the chuck I3 by means of a shaft 3I disposed through an opening 32 in the chuck I3. The upper ends of thestraps 39 surround eccentrica 33 on a worm wheel 34 which is rotatable on a shaft 39. The worm wheel 34 carries a projecting member 39 for manual operation thereof as hereinafter described. As shown in Figures 1 and 2 the wheel 40 u is not provided with teeth around its entire periphery, but as will be shown hereinafter, this is not necessary since the teeth on only one'portion of the wheel 34 are used.
Adjacent the worm wheel 34 and in engage- 45 ment with theiteeth thereof is a worm I1. At
the point where the worm 31 enters the housing 9,' the worm 31 is reduced andis carried in a bearing 39. The bearing 39 is provided 'with recesses 39 to receive the inner ends of studs 40. With this construction the worm 31 is free vto rotate on its vertical axis and at the same time the bearing 39, together with the worm 31 may l be rocked on a horizontal axis; v
The lower end. of the worm 31 is carried in a bearing 4I which is provided with a lip 42. lThe lip 42 of the bearing 4I is normally engaged by a hooked portion 43 of a lever 44 carried on a pivot 49 in the housing 9. A spring 49 vhas its ends connected respectively to the lever 44 and the housing 9.so as .to maintain the hook `43 in engagement with the lip 42 on the bearing 4l. The lever 44 on its .inner end is provided with a curved extension 41 in the path of movement of the chuck i3.
Disposed adjacent the bearing 39 is a plunger 49, provided with a spring 49. The plunger 49 is carried in a recess inthe upper part ofthe 4 75 suitable manner. The casing of the motor 5I is provided with the usual hand grip 52 and the usual trigger switch 53 toy start and stop the motor 5I. 'Ihe usual cable 54 is provided` to supply electric current from a source of power to the motor 5I. It will be obvious that other means to rotate the worin 31 might be substituted for the motor 9|, but the motor- 9| is desirable for speed, power and'ease of operation.
The operation of the device is as follows:
The rivet C is rst placed on the mandrel A. The lower edge of the rivet C will abut the tapered head B of the mandrel A. y The mandrel'A is then inserted inthe chuck I3. In order to insert the mandrel A the chuck I3 is placed in the position shown in Figure -1. The control plate lever 2| is operated by the'extension 22 to the dotted line position shown in Figure 7.. This draws the control plates I9 upward and carries the gripping rolls I9 to the upper extremities of the angular slots I9. The shank of the mandrel A may then be inserted through the bore I2 in the nose II and into the bore I4 in thechuck I3. When the mandrel A has been inserted to a point where the ilange D ofthe rivet C abuts the nose II, the lever 2I is released and the rolls I6 grip lthe shank of the mandrel A in the bore I4.
At this time the worm 31 is in engagementwith ated to apply power to the motor 5I and cause` rotation oi' the worm- 31. As the worm 31 rotates the wheel 24 is turned on-its shaft 35 and carries with it the eccentrics 33 which draw the straps 30 upward thereby drawing the mandrel A through the rivet C. As the pressure is applied the head B of the mandrel A spreads the inner end of the rivet C. As the head B encounters the resistance of the plates E together with the resistance of the rivet C, the head A will itself `become deformed so that it may be drawn through the rivet C. When the head B' of the mandrel A is drawn through the rivet C the rivet C is securely set in place as shown in -Figure 2. The. chuck I3 moves sumciently to draw the mandrel A and what was the head B entirely within the bore I2.
As the mandrel A is drawn within the bore I2 the the upper end of the chuck I3 strikes the `extension 41 on the lever 44 and rocks the lever to the position shown in Figure 2. The spring pressed plunger 49 assists to a certain extent in moving the worm 31 out of engagement with the the fact that the line of force from the handle 92 where manual pressure is applied to the rivet C is not straight. 'I'he line of force is through the axis of the worm 31. and is then .onset and continues from the center` of the shaft 35 through the axis of the mandrel A. Therefore, since pressure is applied to hold the flange D Vofl the rivet C against the plates E, when the lower `end'of the worm 31 is released the machine immediately breaks.
When the riveting operation is complete the parts are in the position shown in Figure 2v and the wheelh34 is returned to the position shown in Figure 1 by operation of the extension 36. The extension 36 may be permanently securedon the wheel 34 or may be a separate element insertable therein. In fact, the extension 36 could be climinated except that it gives greater leverage to return the wheel 34 to position. When the wheel 34 is returned to the position shown in Figure 1 the worm 31 is again placed in engagement with the wheel 34. The plunger 48 has merely maintained the worm 31 out of inadvertent engagement. The lower end of the mandrel A will now project from the bore I2. The lever 2l is operated to release the mandrel A, which is withdrawn and a new mandrel A with a rivet C thereon is inserted in the chuck I3, and the machine is ready to set another rivet.
