Abstract
Description
- The invention relates to equipment for coupling - with the aid of a square - the two profiles converging at an angle of a metal frame for casings. Such equipment generally comprises a seat for the components (profiles and square) to be assembled, two calking implements capable of causing the deformation of walls of the profiles to contrast with corresponding rabbets which are present in the square; also provided are an implement for perforating and an implement for injecting, arranged to act on the external corner formed by the two abutting profiles. The active parts of said two implements act essentially in a plane bisecting the dihedron defining the corner of the casing.
- The aim of the invention is to simplify the structure, to allow greater flexibility in handling, and so forth. These and other aims and advantages will become clear from the text which follows.
- According to the invention, on a fixed structure in front of the corner formed by the converging profiles arranged in the seat, there are provided essentially vertical guides for two assemblies, one of which bears the implement for perforating and the other of which bears the implement for injecting, the axes of which implements are situated in and move in the plane bisecting the corner defined by the two converging profiles; also provided, for each of said assemblies, are actuating means for the movement of the respective assembly; the active part of each of the two implements is capable of advancing axially to carry out its own function and then to move back.
- Each of the two actuating means is capable of making the respective assembly reach an adjustable limit of travel which defines the active position of the associated implement.
- Said actuating means can be step motors or equivalent, which actuate threaded bars, with which screw nuts borne by the relevant assemblies interact. Alternatively, the actuating means can be cylinder/piston means controlled hydraulically or pneumatically.
- In one possible embodiment, said fixed structure comprises two plates, between which columns extend forming the vertical guides; the same columns can constitute the guides for both said assemblies.
- The seat for the profiles has support and positioning members, with which external lateral walls of the converging profiles make contact; according to the invention, said support and positioning members can be borne by an assembly which is adjustable in an essentially horizontal direction and parallel to the bisecting plane. Such support and positioning members are adjustable on said assembly in an essentially vertical direction, by column guide means or equivalent.
- The invention will be better understood by following the description and the attached drawing which shows a non-limiting exemplary embodiment of the invention itself. In the drawing, on different scales for convenience of consultation,
- Fig. 1 shows a plan view in partial section along I-I in Fig. 2 of equipment made according to the invention;
- Fig. 2 shows a vertical section along II-II in Fig. 1;
- Figs 3 and 4 show local sections along III-III and IV-IV in Fig. 2;
- Fig. 5 shows a vertical section essentially along the lines V-V in Figs 1 and 2, and
- Fig. 6 shows a section along VI-VI in Figs 2 and 5.
- According to what is illustrated in the attached drawing, 1 indicates in a very concise manner a fixed structure which is situated positioned in front of and in the region of the corner S formed by two profiles P1 and P2 which are placed on the equipment to converge at the angle to which the corner S belongs, to be connected by means of a square SQ inserted inside the two profiles P1 and P2. The seat for the positioning of said profiles P1 and P2 is formed by
components tools 3. Integral with acomponent 1Y of thefixed structure 1X arehorizontal guides 5 which are parallel to the vertical bisecting plane of line A-A in Fig. 1 which is the plane bisecting the corner S formed by the profiles P1 and P2 converging to form the angle of the frame with said two profiles P1 and P2 already indicated. Ablock 7 can be moved and adjusted on thehorizontal guides 5; thisblock 7 can be positioned by means of the angular maneuvering of a threadedshaft 9 with an axis parallel to theguides 5, which can be controlled by means of a coupling withbevel gears 10 from amaneuvering terminal 12 with a quadrangular head or similar. Theblock 7 forms vertical seats for the sliding of twosmall columns 14 which are interconnected by alower bridge 15 and which at the top support twopawls 16 which are capable of being adjusted so as to create supports which are adjustable according to the dimensional characteristics of the profiles to be coupled. Thepawls 16 are adjustable vertically by the sliding and locking of thesmall columns 14 and in the horizontal direction parallel to the bisecting plane of line A-A for the positioning of theblock 7. - The structure X, which is positioned in front of the seat for the corner S of the profiles P1, P2 to be coupled, comprises a pair of
horizontal plates columns 26 which constitute vertical sliding guides.Small support columns 28 serve for the connection of thelower plate 20 to thestructure 1, 1X. In a practical manner, there are threeguide columns 26, two of which are close and aligned parallel to the abovementioned bisecting plane of symmetry of line A-A in Fig. 1; thethird column 26 is removed from and on the opposite side to the pair ofcolumns 26 in relation to the bisecting plane of line A-A in Fig. 1. - Two
assemblies columns 26. Thelower assembly 32 is shaped like a rectangular frame (see in particular Fig. 6) equipped with a threadedbush 36, with which a threadedshaft 38 is coupled; saidshaft 38 is controlled by anactuator 40 which can be constituted by an electric step motor or another equivalent; by means of theactuator 40, theassembly 32 can be raised and lowered along thecolumns 26. Theassembly 32 has two horizontal guides 42 (see in particular Fig. 6) which have a development parallel to the bisecting plane of line A-A and on which horizontal guides 42 agroup 44 slides which bears themotorization 46 of a perforation implement 48, the horizontal axis of which, parallel to theguides 42, lies in the vertical bisecting plane of symmetry with line A-A referred to a number of times. The movement of thegroup 44 along theguides 42 and parallel to the axis of the perforatingimplement 48 can be obtained by means of anactuator 50, such as a step motor or another equivalent, with a threadedshaft 52 which engages in a threadedbush 54 integral with thegroup 44. In this manner, a perforation can be obtained with theimplement 48 in the region of the corner S of convergence of the two profiles P1 and P2. Theactuator 50 controls theimplement 48 in the advance direction and in the return direction, which in turn is actuated in rotation by means of themotorization 46. The perforation with theimplement 48 can be actuated at a level which is adjustable by means of the positioning of theassembly 32 and therefore of thegroup 44 on theguide columns 26; adjustment can be actuated electrically when theactuator 40 is a step motor or equivalent. - The
assembly 34, shaped similarly to that 32 and bearing (see in particular Fig. 1) a pair ofhorizontal guides 56 which are similar to those 42 and on which agroup 58 similar to that 44 can slide, also slides on thecolumns 26. Theassembly 34 is equipped with a threadedbush 60 which is coupled to a threadedshaft 62 formed vertically which can be controlled in rotation by means of anactuator 64 similar to that 40 and for example also constituted by a step motor or another equivalent. Theactuator 64 moves theassembly 34 vertically along thecolumns 26 independently of theassembly 32. Thegroup 58 forms a sliding seat parallel to theguides 56 for anozzle 66 of an injection tool for an adhesive with which provision is to be made for sticking the square SQ inside the profiles P1 and P2 for locking the connection. The implement for injecting 66 is situated parallel to the perforatingimplement 48 in the plane A-A referred to a number of times. Thisimplement 66 for injecting is slidable on its own axis guided by arod 68 and stressed by aspring 70 towards the corner S to offer a tolerance for adaptation to the hole. Thegroup 58 can be controlled for sliding along theguides 56 by means of anactuator 72 similar to that 50, which controls a threaded shaft 74 which is coupled to abush 76 borne by thegroup 58. The assembly 34 - and with it the group 58 - can be adjusted vertically along thecolumns 26 by means of theactuator 64, with a positioning which is expediently fixed, perhaps electrically or by a system of the type of a mechanical pawl; in this manner, positioning of the implement for injecting 66 is achieved in perfect alignment with the hole which has previously been formed, by means of theimplement 48, along the corner S through the material of the profiles P1 and P2 and if appropriate of the square SQ also. - In operation, provision is initially made for bringing the
assembly 34 of theinjector 66 upwards into an inactive position while theassembly 32 can be moved by raising it as far as a desired level in order to be able to proceed with the perforation with theimplement 48 in the corner S along the bisecting plane of line A-A, at a desired level in relation to the profiles P1 and P2 which have been placed in the seat defined by thesquares 16 and by the supports formed by thestructure 1X. After having carried out the perforation, theassembly 44 of the perforatingimplement 48 is lowered and theassembly 34 is lowered followed by the point of the implement for injecting 66 until it is made to coincide with the geometrical axis along which the perforation has been effected by theimplement 48 in the region of the corner S of the frame being formed. Provision is then made - with the advance of the group 58 - for pressing the point of the injecting implement 66 into the hole previously formed by theimplement 48, the pressure for coupling the end of the injectingimplement 66 being ensured by thespring 70 which yields with the advance of thegroup 58 by means of theactuator 72. - With each operation effected for the perforation and for the injection of the adhesive, the
respective groups respective actuators respective assemblies respective actuators - The operations of perforation and of injection can be repeated at two different points of one and the same corner.
- The adjustments necessary for adaptation to the morphology and to the dimensional characteristics of the profiles P1 and P2 are thus obtained, by independent operations and therefore with considerable flexibility for adaptation to the requirements of individual manufacturing processes. The equipment can be made in a relatively very simple and economical manner given the standardization of the components which can be used. These and other aims and advantages will be evident to experts in the field.
- It is understood that the drawing shows only an example given only by way of practical demonstration of the invention, it being possible for this invention to vary in form and arrangement without however leaving the scope of the concept which forms the invention itself. Any presence of reference numbers in the enclosed claims has the aim of facilitating reading of the claims with reference to the description and to the drawing and does not limit the scope of protection represented by the claims.
- The actuators can also be different from those which are electric step motors and for example can be constituted by pneumatic or hydraulic cylinder/piston or equivalent systems, equipped with appropriate limits of travel which are adjustable for defining the position of the common axis on which the
implements
