Therefore, for the surface treatment of indented or recessed inner surfaces in automated operation, a robot with at least five degrees of freedom is needed, but it is extremely costly and economically disadvantageous for a wide range of products.

Uvedené nevýhody odstraňuje zariadenie pre naklápanie striekacej pištole podía vynálezu,ktorého podstata spočívá v tom, ze držiak pištole je uchytený na hriadeli ozubeného segmentu,ktorý svojím ozubením je v zábere s ozubením ťahadla spojeného s prvým priaroočíarym motorem,kde ťahadlo je posuvné uložené v puzdre, na jednom konci ktorého je upevněné ozubené kolesoa na ktorého druhom konci je otočné uložený hriadeí ozubeného segmentu, pričom toto ozubenékoleso je otočné uložené v telese, pevne spojenom s plášťom druhého priamočiareho motora,majúceho odstupňovaný prierez, v ktorého oboch koncových častiach, majúcich oproti strednejčasti vačší prierez, sú uložené krajné plavné piesty a v strednej časti stredný plavnýpiest, opatřený na svojom obvode ozubením, ktoré je v zábere s ozubeným kolesom, a vo svojejvnútornej častí dutinou pre plavné dorazy opreté o pevné podložky umiestnené na okrajochdutiny stredného plavného piesta a o osadenie centrálneho trna, na ktorom sú posuvné uloženévšetky plavné piesty a plavné dorazy. Medzi plavnými dorazmi je pružina. Výhodou zariadenia pre naklápanie striekacej pištole je, že jeho připojením na koncovérameno manipulátora vzniká taká kinematická sústava, ktorou pri naklápaní pištole do piatichpolóh, možno v niektorých prípadoch aplikácie, konkrétné u nanášania vnútorného povrchukúpacích vání, nahradit zložité technologické zariadenie, či striekací robot. Přitom zariadeniepodlá vynálezu je výrobně jednoduché a funkčně spoíahlivé. Příklad vyhotovenia zariadenia pre naklápanie striekacej pištole podlá vynálezu jeznázorněný na výkresoch, na ktorých obr. 1 představuje rez zariadením v rovině kolmej nasměr pohybu striekaného predmetu zavěšeného na visutom dopravníku a prechádzajúceho striekacoukabinou, obr. 2 rez zariadením v rovině rovnoběžněj so smerom pohybu striekaného predmetu,obr. 3 schému naklápanie pištole v niektorých jej polohách pri povrchovej úpravě vnútrajškukúpacej vane a obr. 4 schematický priestorový pohlad na všetky polohy, ktoré je možné zariade-ním na naklápanie pištole dosiahnuť.The above drawbacks are eliminated by the spray gun tilting device of the present invention, wherein the gun holder is mounted on a toothed shaft of a toothed gear engaging with a toothing of a puller coupled to a first auxiliary motor, wherein the puller is slidably mounted in the housing. at one end of which a gearwheel is mounted at the other end of which is a pivot shaft of the gear segment, the gearwheel rotatably mounted in a body fixedly connected to the housing of a second linear motor having a graduated cross-section in which both end portions are larger than the middle portion a cross-section, the outermost pistons and, in the middle, a central float, provided on its periphery with teeth which engage with the gearwheel, and in its inner part a cavity for float stops supported by fixed washers placed on the edges of the cavity of the middle Plavného piston and the shoulder of the central mandrel on which the pusher pistons and floatingly uloženévšetky floatingly stops. There is a spring between the float stops. The advantage of the device for tilting the spray gun is that its connection to the end bar of the manipulator creates such a kinematic system, which in the tilting of the pistol to five positions, in some cases applications, particularly in the application of internal surface bathing, replace a complex technological device or spray robot. The device according to the invention is simple to manufacture and functionally reliable. 1 shows a cross-section of the device in the plane perpendicular to the direction of movement of the object to be sprayed, suspended on a suspension conveyor and passing through the syringe, FIG. 2 shows a section through the device in a plane parallel to the direction of movement of the object to be sprayed, FIG.

The central shank fl is provided with an axial bore 18. The tilt function of the pistol is as follows: In case a flat panel is to be surface treated, which is prior to entering a pressure chamber is introduced into the first space 35 of the one-way straight-line engine 32. The piston 34 of this engine 32 pushes the pulling bar 30 forward and the other side of the barrel. The pistol holder 26, which is fixedly connected to the shaft 27, tilts the pistol 25 to the fifth position V. The device is prepared by this power to surface the flat parts. If it is necessary to finish the inner cavity with spit-sloping walls such as bath tub 24, then the pressure medium is introduced into the second space 36 of the single-track rectilinear motor 32. The piston with piston rod 34 is shifted to the rear, carrying the toothed rack 3J with it. 28 and the pistol holder 26 through the shaft 27 to the initial position J). At the same time, the pressure medium is fed to the first space 21 and the second intermediate space 20 of the combined linear motor. The first outermost piston 11 is moved to the drawing position and the single piston 2 arrives at the first extreme piston 11 and stops. The rack tooth 3 rotates the toothed wheel 6 and at the same time the housing 5, on which the gear 4 is tilted, the pistol 25 to the first position I. Once the pistol 25 is required to return to the initial position 2 * the pressure medium in the first space 21 is canceled and the first intermediate space 20, the spring 17 establishes a middle float piston 2 in a central position corresponding to the starting position 0 of the pistol 5. This is due to the fact that the float stops 6, 7 are abutted on one side of the housing face 15 and 15 respectively. o shoulder 1.6 on central spindle 2 · spring 17 keeps the intermediate piston 2 in contact with the intermediate spaces 19 and 20 with the outflow of pressure distribution always in a neutral, central position. For example, if the pistol 25 is to be tilted to the fourth position IV, a pressure medium is introduced into the first interspace 19, whereby the second interspace 20 and the second space 22 are connected to the downstream branch of the pressure distribution. The intermediate piston 2 is moved to the right, pushing a second outermost piston 12 in front of it, to this end at the second lid 9 of the combined linear motor 2. When moving the middle float piston 2 to the right, the first solid support 13 and the floating float stop 6 are carried along with it and the spring 17 is pressed. As soon as the pressure medium is transferred from the space 19 to the discharge branch of the pressure distribution, the spring 17ce returns the central stop 6 to the middle of the floating piston 2 until the left stop 6 abuts the housing 15. The pistol 25 returns the opal to the position 0. to the second position II and the third position III.
