Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): refer to fig. 1, do the utility model discloses a frock is riveted to pressure of generator cowling panel, including pressure head 1 and pressure riveting base 2. The pressure head 1 is driven by the pressure riveting cylinder, and the below of pressure head 1 is equipped with fixed plate 3, and pressure head 1 contradicts on fixed plate 3. An upper die holder 4 is arranged below the fixed plate 3. The welding of the below of fixed plate 3 has L type mount 5, and the vertical end vertical connection of L type mount 5 is in the below of fixed plate 3, and L type mount 5 is equipped with two at least, and two L type mounts 5 set up in opposite directions, and upper die base 4 slides and wears to establish between two L type mounts 5, and the below vertical welding of upper die base 4 has a plurality of squeeze riveting posts 6, and the position of squeeze riveting post 6 corresponds with the position of squeeze riveting hole.

Referring to fig. 1, when workpieces of different specifications need to be machined, a worker slides out the upper die base 4 from the lower side of the fixing plate 3, and then the upper die base 4 of the required machining specification is replaced with the upper die base 4 of the required machining specification and penetrates between two L-shaped fixing frames 5.

Referring to fig. 1 and 3, in order to reduce the possibility that the upper die holder 4 slips out from under the fixed plate 3, the positional stability of the upper die holder 4 under the fixed plate 3 is improved. So at the below fixedly connected with fixed block 7 of fixed plate 3 (fixed block 7 and fixed plate 3 integrated into one piece), fixed block 7 sets up the one side of keeping away from L type mount 5 at fixed plate 3, and the welding has backup pad 8 in one side that fixed block 7 is close to L type mount 5 simultaneously, offers the constant head tank 401 that corresponds with backup pad 8 on upper die base 4. The staff slides in two L type mounts 5 between with upper die base 4 from the one side that fixed plate 3 below is close to L type mount 5, makes constant head tank 401 card go into backup pad 8 upper portion, and the side of upper die base 4 is contradicted in one side that fixed block 7 is close to L type mount 5 to make upper die base 4 wear to establish the below at fixed plate 3 more steadily.

Referring to fig. 1 and 2, since the squeeze of the squeeze post 6 is directly above the rivet, there may be a phenomenon in which the rivet stem is broken or the top of the rivet is cracked. Therefore, the guide posts 9 are vertically welded on the press riveting base 2, four guide posts 9 are arranged along the outer side of the press riveting base 2, an arc chamfer is arranged above the guide posts 9, and the guide posts 9 are slidably provided with the floating plates 10 in a penetrating manner. The rivet pressing base 2 is provided with accommodating holes 11, the accommodating holes 11 are uniformly formed in the rivet pressing base 2, rubber springs 12 are arranged in the accommodating holes 11, the rubber springs 12 extend out of the accommodating holes 11, and the accommodating holes 11 are correspondingly formed in the lower portion of the floating plate 10. The squeeze riveting cylinder drives the squeeze riveting column 6 to move downwards, when the squeeze riveting column 6 is in contact with a rivet, the floating plate 10 slides downwards along the guide column 9 under the action of the squeeze riveting column 6, and the rubber spring 12 below the floating plate 10 plays a role in buffering the direct squeezing rivet of the squeeze riveting column 6.

Referring to fig. 1, the squeeze riveting cylinder drives the squeeze riveting column 6 to move downwards, so as to reduce the phenomenon that the squeeze riveting column 6 continuously squeezes rivets to cause damage to workpieces. Therefore, the limiting columns 13 are welded below the upper die base 4, the two limiting columns 13 are vertically arranged, when the floating plate 10 is attached to the pressure riveting base 2, after the pressure riveting process is completed, the limiting columns 13 are supported between the upper die base 4 and the pressure riveting base 2, and the limiting effect is achieved on the position of the upper die base 4.

Referring to fig. 1 and 2, a connecting arm 14 is bolted above the fixed plate 3. The support column 15 is vertically welded on the pressure riveting base 2, the positioning sleeve 16 is slidably arranged above the support column 15 in a penetrating mode, two ends of the connecting arm 14 are respectively sleeved on the positioning sleeve 16 in a penetrating mode, the support column 15 is sleeved with the telescopic spring 17, and the telescopic spring 17 is arranged below the positioning sleeve 16. The riveting column 6 extrudes the rivet downwards to rivet, the riveting column 6 and the connecting arm 14 move downwards simultaneously, the positioning sleeve 16 drives the connecting arm 14 to move downwards along the supporting column 15, the movement path of the pressing head 1 has a guiding effect, and the possibility that the pressing head 1 is inclined when moving downwards to rivet is reduced. When the riveting is completed, the upper die base 4 moves upwards to return to the initial position, the telescopic spring 17 can generate upward elastic force, the positioning sleeve 16 slides upwards along the supporting column 15, and the phenomenon that the positioning sleeve 16 is blocked when sliding upwards along the supporting column 15 is reduced.

The implementation principle of the embodiment is as follows: according to the specification of the required work piece of riveting, with supporting upper die base 4 slidable mounting in the below of fixed plate 3, upper die base 4 slides in between two L type mounts 5 from the one end that fixed plate 3 below is close to L type mount 5, and the staff promotes L type mount 5, makes constant head tank 401 joint in backup pad 8 top, has improved the positional stability of upper die base 4 in fixed plate 3 below. The pressure riveting cylinder drives the upper die base 4 to move downwards, the pressure riveting column 6 is abutted to the rivet, the pressure riveting column 6 extrudes the workpiece to move downwards together with the floating plate 10, and when the floating plate 10 is tightly attached to the upper side of the pressure riveting base 2, the pressure riveting column 6 continues to extrude the rivet, so that the rivet is connected with the workpiece in a pressure riveting mode.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
