Summary of the invention

The present invention relates to a kind of for thering is connecting rod (or the bar blank of small end and large end, be processed to represent many features of final products but lid and bar still form the blank of the part of described same metal body) machine that rises and break as bar portion and cap, described machine comprises:

Setting element, it is for disconnected position that described connecting rod is positioned to rise;

Inflatable element, it is inserted in the hole of described large end of described connecting rod, take just can be by described connecting rod cracking as bar portion and cap by described inflatable element is expanded.

According to the present invention, described setting element comprises the first setting element, described the first setting element against the described large end of described connecting rod (for example, depart from the described screw hole place of described large end or described large end immediately, or be even inserted in described screw hole, be inserted into and have no progeny for described cap being screwed to the hole in described bar portion rising), (this makes to arrange more flexible to be preferably located in the described cap end of described connecting rod; Can make described the first setting element be partial to against described large end, for example abut against the described screw hole of described large end, same other end from described macropore, approaching the end of described small end, but subsequently just can not be with the setting of connecting rod: the described screw hole in described connecting rod is only towards the described lid end opening of described connecting rod; Therefore, provide flexibility and its utilization to variety of products of inserting or just having promoted described machine from described first positioner of described cap end).Described the first setting element comprises two the first setting elements, described in each, the first setting element can be displaced sideways and (or move horizontally, described lateral can be preferably horizontal direction) so that the position of adjusting described the first setting element is to the distance between the described screw hole of described connecting rod.Like this, described machine can be used for processing dissimilar connecting rod, presents the feature of the different distance between the described screw hole on described large end.

Described in each, the first setting element is all for optionally adopting of multiple precalculated positions in side direction (or level) direction, make it to be suitable in selected multiple preset distance to adjust described machine, described preset distance is the distance between described screw hole.This just makes to switch fast between the production of different connecting rods and becomes easy: described setting element is easy to being displaced sideways to adopt described predetermined lateral position, and described predetermined lateral position is corresponding to by processed new links type.

Described in one of them, the first setting element can be installed on the first detent bracket, described in another, the first setting element can be arranged on another first detent bracket, and described the first detent bracket can be displaced sideways (or moving horizontally) so that described the first setting element moves between described precalculated position.Therefore, by making described bracket for example move (described horizontally-guided element is associated with standing part or the framework of described machine) along horizontally-guided element, described the first setting element is optionally set to one or the other in described precalculated position.

Described in each, the first detent bracket can be provided with multiple the first coupling arrangements, described the first coupling arrangement is set to the second coupling arrangement and interacts, described the second coupling arrangement is associated with standing part or the framework of described machine, and (standing part of described machine can be a part for the Part I of described machine, or be fixed to the Part I of described machine), like this, by connecting described the second coupling arrangement and described the first coupling arrangement, described in each, the first detent bracket is limited in ad-hoc location, wherein, the corresponding precalculated position described in one of them of the first coupling arrangement described in each.Therefore, by selecting one of them specific described first coupling arrangement and being connected to described the second coupling arrangement, described the first detent bracket is limited in a position, makes corresponding described the first setting element just be limited in one of them specific described precalculated position.

Described the first coupling arrangement can comprise multiple openings or hole, and described the second coupling arrangement can comprise at least one limiting element, and described limiting element is inserted in one of them selected described opening, to limit being displaced sideways of corresponding described the first detent bracket.The separately position of opening in can corresponding described precalculated position described in each.Therefore,, by described limiting element being inserted into one of them or described in another in opening, corresponding described the first setting element is limited in one of them or another position in described precalculated position.

Described opening can be distributed in described vertical direction or the direction vertical with described lateral.Sometimes preferably, the difference between the different described precalculated positions of described aperture efficiency wants large, therefore can preferably described opening be put into different height to prevent opening and other superposition of end gap described in one of them.Equally, in order to help to select to insert the described opening of described limiting element, the distribution on this height is also favourable.

Described limiting element can move in the vertical direction, to be inserted in one of them selected described opening, to corresponding described the first setting element is positioned to one of them selected described precalculated position.This makes described machine be adapted to easily the manufacture of selected links type, between the described screw hole at the described large end place of described connecting rod, there is specific range: described adaptation is undertaken by described limiting element being arranged on to the upright position (this can be labeled or mark on described machine) of relatively described bar and being introduced into corresponding described opening (for example, by being screwed, using handwheel or homologue).

With the joining described limiting element of the first detent bracket described in one of them, and the described limiting element connecting with detent bracket described in another can engage by connected structure, make them in described vertical direction, jointly move (for example moving along vertically-guided element), described connected structure is associated with restraint device, and described restraint device is used for limiting described connected structure (11D) certain height (for example, by limiting to opening or hole insertion pin).Because it can be positioned described limiting element vertical direction and simply all at equal height, select to insert the specific range between described opening or hole and described first setting element of described limiting element with this, so this is favourable.

Described in each, limiting element all has point, and the diameter of described point reduces towards described limiting element.For example, described tip can be oblique, conical and/or truncated taper shape, for being inserted into described opening.This can help the change of the position of described the first setting element substantially: described limiting element can be corresponding opening and placing described in one of them, make its tip enter described opening.Even if the relatively described opening of described limiting element is not in middle, described tip will enter described opening, due to its shape, inserts in the process of described opening at it, and it will make described bracket be displaced sideways when needed, to guarantee correct centering.Can select the size of described limiting element, like this, once it is inserted into the restriction site in described opening, it will coordinate well in described opening.

The specific embodiment

Fig. 2 A and 2B have illustrated according to machine of the present invention, this machine comprises basic frame, this frame comprises fixing Part I 1, is associated and comprises that the Part II 2 of first (mainly) bracket (21) is slidably mounted between proximal location and remote location with Part I 1.Part II 2 further comprises that the second bracket 22, the second brackets 22 are slidably arranged in the first bracket, and the second bracket 22 can be moved around in described the first bracket 21.Actuator or driving arrangement 25 are located on the first bracket 21, controllably to make the second bracket move in the first bracket, for example, make the second bracket deflection stop part (stop) 26 in the loading stage of machine operation.

As shown in Figure 3, the first half housings or sleeve part 19 is attached to Part I 1, the second half housing by screw 190 or sleeve part 29 is attached to the first bracket 21 by screw 290.In the time that these two sleeve parts 19 and 29 link together (in the time that the first bracket is positioned at proximal location, as shown in Figure 3), these two sleeve parts 19 and 29 just form protuberance (protrusion), when connecting rod 1000 is arranged on machine to rise (as shown in Figure 2 B) when disconnected, this protuberance enters in the macropore of connecting rod 1000.These sleeve parts form a part for expansion element 3, and this expansion element 3 further comprises two and half expander mandrels 31 and 32, and this two and half expanders mandrel 31 and 32 is positioned at the sleeve or the cylinder that are formed by the first sleeve part 19 and the second sleeve part 29.One of them expander mandrel part 31 is attached on the Part I 1 of machine, and another expander mandrel part is attached on the first bracket 21.Because advancing of splitting wedge 33 is mobile, quilt separates above-mentioned half expander mandrel.Splitting wedge can be activated by any applicable actuating device, for example, as shown in Figure 5, although sometimes preferably use electronics press 4, the conventional hydraulic actuator conventionally adopting in this machine.

Except the sleeve being formed by the first sleeve part 19 and the second sleeve part 29, be also provided with the positioner of several connecting rods for placed machine.The first positioner is arranged on Part I 1, and comprise the first setting element 11, the first setting element 11 moves forward and backward by corresponding actuator, and this actuator is arranged in bracket 11A (literary composition is called the first detent bracket), and bracket 11A is arranged on the Part I 1 of machine.The first setting element 11 is set to insert at least in part in the screw of connecting rod, and described screw is used for holding screw, and this screw is connected to bar portion by cap rising to have no progeny, as shown in Figure 4.These first setting elements comprise: main shaft part or main shaft portion 111, and main shaft part or part 111 are inserted described screw from the cap end of connecting rod; With contact-making surface 110 or adjacent part, when in the operating process at machine, when setting element is with to connecting rod, the cap of contact-making surface 110 or adjacent part butt connecting rod, therefore makes it towards the first sleeve part 19 bias voltages, and contacts with described the first sleeve part 19.Therefore main shaft part becomes inserts in screw completely.As shown in Figure 4, main shaft part 111 comprises fluid issuing 12, in machine running process, and the cleaning solution that can provide continuously or flow out from these outlets 12 discontinuously.These outlets can be orientated the fluid impact cap that flows out from these fluid issuings 12 while making to rise disconnected generation and/or the disconnected surface of rising of bar portion as, thereby contribute to remove discrete particles.

On the other hand, as shown in Figure 3, more fluid issuings 13 are located in Part I 1 and the first bracket 21, and the region adjacency that both contact with sleeve part 19 and sleeve part 29, thereby, when rising when disconnected, provide more multithread body to the disconnected surface of rising, thereby contribute to remove discrete particles.

Fluid for example can be compressed air.

More be used for positioning linkage rod so that the disconnected positioner that rises comprises centrepin (centering pin) 23 and two additional locators 24,1005, two additional locators 24 of aperture that centrepin 23 is set to pack into connecting rod are configured such that the large end of connecting rod departs from centrepin 23.Centrepin 23 and additional locator 24 are arranged on the second bracket 22, and as mentioned above, the second bracket 22 is interior removable at the first bracket 21.The positioner object of installing that suspends is like this to reduce excessive pressure or power, and in the starting stage of rising by disconnected operation, excessive pressure or power can be damaged connecting rod.

According to the present embodiment, in the time that connecting rod is put in machine, the second bracket 21 is propped up stop part 26 by actuator 25 bias voltages, and in connecting rod insertion machine, like this, centrepin 23 enters in the aperture of connecting rod.Centrepin 23 can, by external force towards Part I displacement, to promote the correct location of connecting rod, suitably be placed connecting rod, so that sleeve 19 and 29 enters in the macropore 1006 of connecting rod.

Once locate connecting rod, just promoted the first setting element (, towards connecting rod) forward, main shaft 111 enters in screw, contact-making surface 110 is in abutting connection with the cap of connecting rod, like this, connecting rod just securely bias voltage prop up and contact the first sleeve part 19; Therefore, the actuator of the first setting element (being arranged in the first detent bracket 11A) and actuator 25 can make connecting rod bias voltage the first sleeve part 19.This has just produced little gap between the inner surface of the macropore of connecting rod and the second sleeve part 29.

In the time that splitting wedge 23 starts to advance, the second sleeve part 29 is forced to, away from the first sleeve part 19, move towards the small end of connecting rod; The first bracket 21 that the second sleeve part 29 is installed also can move in an identical manner.If the small end of connecting rod has been fixed on the first bracket 21, connecting rod there will be tension force, and this is because the first sleeve part 19 has stoped the movement of the large end of connecting rod.But because centrepin 23 is arranged on the second bracket 22, the second bracket 22 is suspending with respect to the first bracket 21, therefore, in the case of not considering the initial movable of the first bracket 21, connecting rod still can remain on its initial position, and can not bear too much pressure.Therefore, these tension force or pressure there will not be, or are at least greatly reduced.

Once the second sleeve part 29, in abutting connection with the inner surface of the macropore of connecting rod, according to indentation or the homologue made in a conventional manner by for example laser in advance, rises disconnected in common mode.Have no progeny rising, separately, due to the movement of the first bracket 21, bar portion is away from cap for bar portion and cap.

Fig. 5 has illustrated the utilization of electronics press, but not the hydraulic pressure press using traditionally.Advantage wherein has been described above.

In order to make machine be adapted to dissimilar connecting rod to be processed, be necessary to change the distance between the first setting element 11, so that this distance is adapted to the distance between the screw on the lid end of connecting rod to be processed, like this, main shaft part 111 can be inserted in described screw, or if the first setting element does not comprise this class main shaft part, contact-making surface 110 is by the large end adjacency of the region of the point required or described large end and connecting rod.For this reason, the first setting element 11 can be arranged in the first detent bracket 11A, and the first detent bracket 11A is movable sideways along horizontally-guided element 11F, as shown in Figure 6.These director elements 11F is associated with the standing part 1A of machine, standing part 1A relatively for example machine Part I 1 and fix.Handwheel 11G is arranged on described standing part 1A, be used for making limiting element (blocking elements) 11C displacement, described limiting element 11C is used for the first detent bracket to be limited in selected position, and the position of selecting described in each is corresponding to the predefined position of corresponding the first setting element 11.Therefore,, by the first detent bracket is placed on to selected ad-hoc location, machine just, applicable to the connecting rod of producing particular types, has specific distance between the screw of this connecting rod.

How Fig. 7 is the first detent bracket if illustrating arranges multiple distributions opening 11B in vertical direction.Described in each, opening also has ad-hoc location and (see that First view seems all opening 11B all on the same position along trunnion axis, but this is only because opening is larger than their alternate position spikes in the horizontal direction in fact in side direction or horizontal direction; Range difference between the screw of different connecting rods can be very little, and therefore, the lateral displacement of the first detent bracket conventionally can be very not large, and the first detent bracket horizontal displacement need to be used for making machine to be applicable to different types of connecting rod; But, can preferably use the sizable opening 11B of opening; For example, preferably, in the time that the rectangular projection of all openings on trunnion axis is overlapped, Duplication is higher than 50%, because in the time switching to another opening from an opening, this can help the insertion of limiting element, this will say clearly in the following discussion).

Therefore,, by limiting element 11C being inserted in one of them selected described opening 11B, bracket 11A can be placed on a specific lateral/horizontal position corresponding to the ad-hoc location of the first setting element.Fig. 8 A shows and how above-mentioned limiting element 11C is set on the horizontal plane of above-mentioned second opening 11B, and by rotation hand wheel 11G, limiting element is introduced and in this opening, arrived the position shown in Fig. 8 B, in this position, described limiting element can well coordinate with described opening 11B, thereby bracket 11A is limited in to certain selected lateral position.

As shown in Fig. 8 A and 8B, limiting element 11C has conical end.How Fig. 7 makes all opening 11B all have to make its substantially overlapping size when projection on trunnion axis if illustrating.; when limiting element 11C moves so that it while becoming in another opening that inserts these openings from insert one of them openings of these openings on the longitudinal axis; the tip of limiting element will be consistent with new opening, has therefore avoided needing " manually " to be displaced sideways bracket tip can be inserted in corresponding opening.Now, when rotation hand wheel is when introducing new opening by limiting element, due to the inclination feature of end and in the time that limiting element inserts being completely slidably matched of limiting element 11C and opening 11B, the propulsion of limiting element 11C will make bracket 11A be moved laterally to its desired position.

Fig. 9 and Figure 10 illustrate the vertically-guided element 11H for connected structure 11D, and by connected structure 11D, the limiting element 11C corresponding with two bracket 11A and the handwheel 11G being associated thereof are bonded with each other.This director element is arranged on the rear portion of the standing part 1A of machine, and comprises multiple opening 11J, and described in each, opening is corresponding with one of them the opening 11B on bracket 11A.By slot 11I, can see from rear portion the opening 11B bracket 11A, limiting element 11C is shown in Fig. 8 A and 8B through slot 11I().

In the position shown in 9, limiting element 11C is associated with the minimum opening 11B of two bracket 11A.In order to change machine, it is manufactured as lower link: this connecting rod has different distance between the screw at lid end place, for example, above-mentioned and second distance that opening 11B is corresponding, the first mobile handwheel 11G of the operator of machine to take out limiting element 11C from opening 11B.Then, operator will pull back restraint device 11E, like this, and the just corresponding pin of pull-out from minimum opening 11J.Then, operator for example manually mentions whole restraint device, this restraint device comprises connected structure 11D, handwheel 11G and the limiting element 11C being associated, until the pin (not shown) of limiting element 11E arrives the position of second above-mentioned opening, in this position, operator makes pin (such as the pin of spring load) enter this opening.This is corresponding with the position in Fig. 8 A.Operator can rotate handwheel simply limiting element 11C is introduced in second above-mentioned opening 11B now, limiting element being inserted in the process of each opening 11B, two bracket 11A are displaced to its new position, thereby the first setting element is navigated to appropriate position to manufacture the connecting rod of newtype.
