Description

[0001] The utility model relates to the technical field of flame spraying with a blowtorch, in particular to an adjustable flame spraying device with a blowtorch. Background Art

[0002] Flame spraying technology has developed rapidly in the past 20 years. As a new surface protection and surface strengthening process, it has become a very active branch in the field of metal surface engineering. It uses flame as a heat source to heat metal and non-metal materials to a molten state, and forms a mist flow under the impetus of high-speed airflow, which is sprayed onto the substrate.

[0003] By setting a connecting plate, since the connecting plate is inclined and deviated from the center of the disc, when the slider moves, the disc will be driven to rotate counterclockwise through the connecting plate, and then the rotating plate will drive the slide bar to rotate together, because the slide bar is embedded in the vertical slideway on the surface of the moving plate, when it rotates, it will drive the base to move to the left through the moving plate, so as to adjust the flame spraying distance of the spray gun body. However, this mechanism still has certain defects when used. When used, it can only adjust the flame spraying distance, and cannot meet the requirements of spraying parts with different heights.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] In one embodiment, Figure 1-Figure 3 As shown, an adjustable blowtorch flame spraying device comprises a processing table 15, a base 17 is slidably provided on the upper end of the processing table 15, and the base 17 is connected to a horizontal pushing mechanism for driving it to move toward a flame spraying position. When in use, the horizontal pushing mechanism can control the left and right movement of the base 17, so as to control the flame spraying distance. A fixed rod 11 is vertically provided on the upper end of the base 17, and a sliding rod 26 is slidably provided inside the fixed rod 11. The sliding rod 26 is slidably arranged with a first sliding groove 25 inside the fixed rod 11, and the sliding rod 26 is connected to the output end of the lifting mechanism. A shell 12 is provided on the upper end of the fixed rod 11, and a nozzle 14 for flame spraying is fixed on the side of the shell 12 through a connecting block 13. A mounting socket matched with the fixed rod 11 is provided at the lower end of the shell 12, and a locking mechanism for locking the position of the shell 12 is provided in the mounting socket. When in use, the shell 12 is sleeved on the top of the shell 11 along the opening at the lower end, and then fixed by the locking mechanism, so as to facilitate the disassembly and installation of the shell 11 and the nozzle.

[0023] A limiting mechanism is also provided between the fixed rod 11 and the sliding rod 26, and the limiting mechanism includes a limiting block 24 arranged on the inner wall of the fixed rod 11, and a vertically arranged limiting groove 23 is provided on the outer side of the sliding rod 26. The limiting block 24 is slidably set in the limiting groove 23. In this way, when in use, when the sliding rod 26 in the lifting mechanism is adjusted to a certain height, it can be restricted to prevent the sliding rod 26 from being separated from the first threaded rod 27.

[0024] The locking mechanism includes a spring slot 18 arranged inside the sliding rod 26, and an extrusion link 20 is provided in the spring slot 18. A pressing plate 22 is provided on the left side of the lower end of the extrusion link 20, and the pressing plate 22 slides through the first through-hole on the lower left side of the spring slot 18. The extrusion link 20 is connected and fixed to the inner wall of the spring slot 18 through a spring 19. An extrusion block 21 is provided at the upper end of the extrusion link 20, and the extrusion block 21 cooperates with the inner wall slot of the mounting socket. A second through-hole is provided on the upper left side of the spring slot 18 for easy passage of the extrusion block 21. When the opening at the lower end of the shell 12 is sleeved on the top of the fixing rod 11, it continues to be pushed until it contacts the extrusion block 21. Since the surface of the extrusion block 21 in contact with it is an inclined surface, the shell 12 can be smoothly pushed to the lower end of the extrusion block 21 to complete the cooperation between the extrusion block 21 and the inner wall slot of the mounting socket. At this time, the extrusion block 21 is reset by the action of the spring, and the shell 12 and the nozzle 14 connected thereto are locked and fixed.

[0025] The lifting mechanism includes a transmission screw hole arranged at the lower end of the sliding rod 26, in which a first threaded rod 27 is matched, the lower end of the first threaded rod 27 is fixedly connected to the second bevel gear 29, the lower end of the second bevel gear 29 is rotatably connected to the fixed rod 11, the second bevel gear 29 and the first bevel gear 28 are meshed with each other, the first bevel gear 28 is connected to one end of the output shaft 30, and the other end of the output shaft 30 is connected to the output end of the second motor 31. When in use, the first threaded rod 27 drives the second bevel gear 28 and the second bevel gear 29 driven by the motor to rotate in the screw hole, and the sliding rod 26 can be driven to slide up and down while rotating, so as to adjust the flame-spraying height.

[0026] The horizontal pushing mechanism includes a sliding block 33 arranged at the lower end of the base 17, and a transmission screw hole is provided on the sliding block 33. A second threaded rod 35 is matched in the transmission screw hole. One end of the second threaded rod 35 is rotatably connected to the inner wall of the processing table 15, and the other end is connected to the first motor 16 for driving the rotation thereof. The first motor 16 is arranged on the left side of the processing table 15. A horizontal slide groove 32 matched with the sliding block 33 is provided at the upper end of the processing table 15. The second threaded rod 35 can be driven to rotate in the screw hole by the first motor 16, thereby driving the sliding block 33 to slide inside the horizontal slide groove 32, so as to facilitate the adjustment of the flame spraying distance.

[0027] Example 2

[0028] The left side of the extrusion block 21 is an inclined surface, which can cooperate with the extrusion groove 36 at the bottom of the shell 12. When the shell 12 contacts its inclined surface, the fixed shell 12 can be pushed directly to the bottom of the extrusion block 21 by pressing the pressing plate, which saves time and effort.

[0029] When in use, first start the first motor 16, which drives the second threaded rod 35 to rotate and thus drives the sliding block 33 to move inside the horizontal slide slot, thereby moving the device until the appropriate flame spraying distance is adjusted. Then start the second motor 31, which drives the first bevel gear 28 to rotate through the output shaft, and the first bevel gear 28 drives the second bevel gear 29 to rotate, and the second bevel gear 29 drives the first threaded rod to rotate in the screw hole 27, and the first threaded rod 27 drives the sliding rod 26 to slide inside the first sliding slot 25, thereby completing the height adjustment. When the nozzle 14 needs to be installed, the housing 12 connected to the nozzle 14 through the connecting block 13 is sleeved on the top of the fixing rod 11 through the opening at the bottom thereof, and then pushed downward so that the slot at the bottom thereof matches the extrusion block 21, thereby completing the fixing of the nozzle 14.

[0030] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
