Description

Technical Field

[0001] The utility model relates to the technical field of surface engineering supersonic flame spraying operation devices, in particular to a multi-axis linkage system for supersonic flame spraying of shaft-type workpieces. Background Art

[0002] Supersonic flame spraying technology mainly utilizes the Laval effect. For example, kerosene-like liquid fuel enters the combustion chamber through a small opening, is atomized and ignited after forming a mixed gas with oxygen, and produces a strong gas phase reaction. A large amount of heat energy is released, causing the product to expand violently. When the expanded gas flows through the Laval nozzle, it is constrained by the nozzle to form a supersonic high-temperature flame flow. This flame flow heats and accelerates the spray material and then sprays it onto the substrate surface to form a high-quality coating.

[0003] In order to form a uniform, dense coating with high bonding strength, the workpiece to be processed is usually required to be in a position convenient for spraying or complete a specified displacement or action. For example, the utility model patent: an integrated device for making supersonic flame spraying samples, whose authorization announcement number is CN 212228526U, uses a metal fixed bracket as a carrier to facilitate the fixing of the workpiece body to cooperate with the spraying operation. However, this carrier can only meet the spraying requirements of ordinary plate workpieces, but cannot meet the spraying requirements for shaft workpieces.

[0004] For shaft workpieces, the fixed position of the workpiece during the processing must not only facilitate spraying, but also be able to complete the rotation action to ensure that the coating can be evenly attached to the workpiece. However, if the shaft workpiece needs to complete the rotation action, it needs to be equipped with a dedicated rotation power source. Usually, the supersonic flame spraying site is only equipped with one rotation power source, and a single rotation power source can only drive one shaft workpiece to rotate at a time. When faced with large-scale processing of shaft workpieces, this mode will not be able to meet the production requirements. At the same time, for some shaft workpieces that cannot withstand high temperatures, corresponding fan devices are usually required to cool them down during the supersonic flame spraying process, but the uniformly set fan device not only increases the cost of the device and poses a safety hazard, but also fails to perform targeted and uniform cooling of the workpiece, and the use effect is poor.

[0005] Therefore, designing and preparing a multi-axis linkage system that can perform supersonic flame spraying on multiple shaft workpieces simultaneously and synchronously is of great significance for improving the spraying processing efficiency of shaft workpieces and reducing production costs.

The power stop lever is fixed on a transmission shaft located at the center of the gearbox, and the power stop lever is arranged perpendicular to the axial direction of the transmission shaft. One end of the transmission connection rod is cooperatively connected to the power source, and the other end is provided with a transmission groove capable of accommodating the power stop lever. The power stop lever is arranged in the transmission groove with a clearance fit, enabling the power source to drive the power stop lever to transmit power through the transmission connection rod, and then driving a plurality of transmission shafts, spur gears, clamping bushings, and shaft workpieces to rotate, so as to realize the synchronous rotation of multiple shaft workpieces under the action of a single power source.

[0009] Further, the fixed bracket is composed of multiple mounting plates connected by bolts.

[0010] Further, the gearbox is composed of a housing A and a housing B arranged in a left-right cooperation manner, and the housing A and the housing B are detachably connected by bolts.

[0031] Next, the technical solutions of the present utility model will be described more clearly and completely in conjunction with the drawings and specific embodiments. It should be noted that the detailed description of the specific embodiments is for the purpose of a comprehensive understanding of the technical solutions of the present invention, and should not be regarded as a limitation on the protection scope of the claims of the present invention.

[0032] A multi-axis linkage system for supersonic flame spraying of shaft workpieces of the present utility model is composed of a transmission main body, a fixed bracket and a power connection mechanism in terms of device structure. Among them, the transmission main body includes a gearbox composed of two metal housings A 13 and housing B 2 as a carrier. In the gearbox, a transmission shaft 5 is supported by a support bearing 14 to complete the cooperation with the gearbox housing, and then the transmission shaft 5 is driven by a spur gear 16 to complete step-by-step transmission. A clamping sleeve 11 for clamping the shaft workpiece 12 is installed on each transmission shaft 5. The transmission main body clamps the shaft workpiece 12 through the clamping sleeve 11, and realizes the transmission effect through the spur gear 16, and then the fixed bracket fixes the transmission main body on the designated operating table. At the same time, the power connection mechanism transmits the rotational power provided by the power source 9 to the power lever 3 through the transmission connection rod 1, thereby driving the entire transmission main body to move.

[0033] The fixed bracket is assembled by multiple mounting plates of different shapes. The fixed bracket includes mounting plate A 17, mounting plate D 18, mounting plate B 19 and mounting plate C 20, which mainly play a role in supporting and fixing.

[0034] The power connection mechanism includes a power lever 3 fixed on the transmission shaft 5 and a transmission connection rod 1 cooperating with the power source 9.

[0035] In the specific assembly of a multi-axis linkage system for supersonic flame spraying of shaft workpieces of the present utility model, the transmission shaft 5 located at the center of the gearbox in the transmission main body is passed through the central hole of the spur gear 16. After moving to the shaft shoulder, the two are welded together using argon arc welding. Two support bearings 14 are respectively sleeved into the positions reserved for the support bearings 14 at both ends of the transmission shaft 5 and are pushed against the limiting section. A plurality of secondary transmission shafts 5 are also respectively passed through the central holes of their corresponding spur gears 16. After moving to the shaft shoulder, the two are welded together using argon arc welding. Two support bearings 14 are respectively sleeved into the positions reserved for the support bearings 14 at both ends of the secondary transmission shaft 5 and are pushed against the limiting section. After completion, the main transmission shaft 5 with the spur gear 16 and the remaining secondary transmission shafts 5 with the spur gear 16 are matched through gear meshing. The main transmission shaft 5 is located in the middle, and the main transmission shaft 5 and the secondary transmission shafts 5 are passed through the circular holes reserved on the matching housing A 13 and housing B 2 together; then the support bearings 14 are snapped into the grooves reserved in the gearbox; then the matching housing A 13 and housing B 2 are buckled, and the matching gearbox is combined and tightened through the bolt holes 6 on the gearbox using fastening bolts 8.

[0036] The clamping sleeves 11 are respectively sleeved on the reserved assembly ends of the main transmission shaft 5 and the secondary transmission shafts 5, and the fastening bolts 8 are screwed into the bolt holes 6 to lock on the bolt holes 6 of the main transmission shaft 5 and the secondary transmission shafts 5 to prevent the clamping sleeves 11 from rotating and falling off.

[0037] As attachedFigure 3 and the attached Figure 4 As shown, 11-1 refers to the clamping bushing that uses bolts to abut against the surface of the shaft workpiece; 11-2 refers to the clamping bushing that uses bolts to abut against one end surface of the shaft workpiece and can stagger-fix the shaft workpiece; 11-3 refers to the clamping bushing that uses bolts to abut against the surface of the shaft workpiece and is equipped with fan blades to provide auxiliary air cooling; 11-4 refers to the clamping bushing that uses bolts to pass through the inner hole of the shaft workpiece and tighten it. 12-1 refers to the shaft workpiece that can be clamped on the surface; 12-2 refers to the shaft workpiece with a larger diameter that needs to be stagger-fixed and can be clamped on the surface; 12-3 refers to the shaft workpiece that requires enhanced cooling during the process and can be clamped on the surface; 12-4 refers to the shaft workpiece whose outer surface cannot be clamped and can be tightened from the inner hole. When specifically used:

[0038] If the shaft workpiece to be processed is a shaft part such as 12-1 that can be clamped on the surface, the clamping bushing of type 11-1 can be used. Insert the shaft workpiece 12-1 to the bottom of the clamping bushing 11-1, and then screw in the fastening bolt 8 until the shaft workpiece 12-1 is firmly pressed.

[0039] If the shaft workpiece to be processed is a shaft part with a larger diameter such as 12-2, the distance between two ordinary clamping bushings 11-1 cannot meet the installation requirements, then the clamping bushing of type 11-2 can be used. The clamping bushing 11-2 includes two types: long and short. They need to be sleeved on the reserved assembly ends of the main drive shaft 5 and the auxiliary drive shaft 5 in an alternating manner of long and short, and the fastening bolt 8 is screwed in through the bolt hole 6 and locked on the bolt holes 6 of the main drive shaft 5 and the auxiliary drive shaft 5 to prevent the clamping bushing 11-2 from rotating and falling off.

[0040] If the shaft workpiece to be processed is a shaft part such as 12-3, the material is prone to deformation when heated, or the temperature is not allowed to be too high during the spraying process, then the clamping bushing of type 11-3 can be used. Insert the shaft workpiece 12-3 to the bottom of the clamping bushing 11-3, and then screw in the fastening bolt 8 of the shaft workpiece until the shaft workpiece 12-3 is firmly pressed. As the shaft workpiece 12-3 rotates, the fan blades of the clamping bushing 11-3 also rotate, and the generated air flow will have an auxiliary cooling effect on the shaft workpiece 12-3.

[0041] If the shaft workpiece to be processed is a shaft part such as 12-4, there is no clamping position on the outer surface and there is a through hole in the middle. Then the clamping bushing of type 11-4 can be used. Pass the long locking bolt 15 of the clamping bushing 11-4 through the central through hole of the shaft workpiece 12-4, and then cooperate with the threaded hole at the end of the threaded locking head 21 of the clamping bushing 11-4 to screw tightly, so as to tighten and fix the shaft workpiece 12-4.

[0042] When assembling the described fixed bracket, one mounting plate B 19, two mounting plates D 18 and a fastening bolt 8 are locked together through bolt holes 6. One mounting plate C 20 is placed upright and locked to the mounting plate B 19 through the bolt hole 6. The mounting plate A 17 is locked to the mounting plate C 20 through the bolt hole 6 and also locked to the mounting plate B 19 through the bolt hole 6. Finally, one mounting plate A, one mounting plate B, one mounting plate C and two mounting plates D are assembled into a set of fixed brackets.

[0043] When assembling the described power connection mechanism, half of the power shift lever 3 is passed through the shift lever through-hole 4 reserved on the main transmission shaft 5, and then the two are welded together using argon arc welding. The transmission connection rod 1 is fixedly fastened to the power source 9.

[0044] It should be noted that bolt holes 6 are left on the back of the housing B 2. The fastening bolt 8 is screwed into the bolt hole 6 on the back of the housing B 2 through the bolt hole 6 on the fixed bracket to lock the two together. Bolt holes 6 are left at both ends of the clamping bushing 11. One end is used to abut and fasten to the transmission main body using the fastening bolt 8, and the other end is used to abut and fasten the clamped shaft workpiece 12 using the fastening bolt 8. The power shift lever 3 and the transmission connection rod 1 adopt a clearance fit with a large gap to ensure that the rotational power can still be transmitted when the power source 9 and the main transmission shaft 5 are not coaxial.

[0045] Furthermore, spur gears 16 of the same specification are used on the transmission shaft 5 to achieve a transmission ratio of 1:1.

[0046] Furthermore, the clamping bushing 11 can be replaced according to different shaft part specifications.

[0047] Furthermore, the clamping bushing 11 fixes the shaft workpiece 12 by means of bolt abutment or bolt tensioning, which is convenient for disassembly and assembly.

[0048] Furthermore, the fixed bracket is assembled using bolt fastening.

[0049] Furthermore, the materials of the gearbox and the fixed bracket are aluminum alloy, the support bearings are standard parts, and the materials of other components are all ordinary carbon steel.

[0050] When the multi-axis linkage system for supersonic flame spraying processing of shaft workpieces of the present utility model is in use, the assembled multi-axis linkage system is placed on the operation tabletop, and the multi-axis linkage system is fixed to the operation tabletop by appropriate means such as clamping or bolt locking. The chuck is used as the power source 9 to clamp and drive the transmission connecting rod 1 to rotate; the transmission connecting rod 1 drives the main transmission shaft 5 to rotate through the power stop lever 3; then the main transmission shaft 5 drives other secondary transmission shafts 5 to rotate synchronously and at the same speed through the spur gear 16; the clamping bush 11 connected to the main transmission shaft 5 and the secondary transmission shafts 5 will rotate together. The shaft workpieces to be processed are respectively inserted into the clamping bush 11, and the synchronous and same-speed rotation of multiple shaft workpieces can be realized under the action of a single power source 9.
