Description

Technical Field

[0001] This utility model relates to the field of thermal spraying technology, specifically to a multi-station thermal spraying fixture for hydraulic piston rods. Background Technology

[0002] The hydraulic piston rod is an important moving component in a diesel engine, transmitting the force generated by gas combustion to the crankshaft. During the operation of a diesel engine, the piston rod is subjected to high temperature, high pressure, and corrosion. At the same time, its surface needs to undergo tens of thousands of friction cycles with the cylinder block during operation. The quality of its surface directly determines the working efficiency and lifespan of the diesel engine. By performing special thermal spraying treatment on the piston rod surface, its wear resistance can be improved, reducing the wear on the cylinder block during piston movement and improving the overall service life.

[0003] An existing patent (publication number: CN218554475U) discloses a multi-station thermal spraying fixture for marine hydraulic piston rods, which can drive multiple sets of parts simultaneously and spray multiple piston rods at one time by activating a servo motor.

[0004] However, the above technical solution still has certain defects. After the hydraulic piston rod is sprayed, the device usually needs to wait for the hydraulic piston rod to cool down before removing it from the three-jaw chuck, and then reinstall the unsprayed hydraulic piston rod, which wastes a lot of time and seriously affects the overall spraying efficiency. Therefore, a multi-station thermal spraying fixture for hydraulic piston rod is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a multi-station thermal spraying fixture for hydraulic piston rods to solve the technical problem of reducing the overall spraying efficiency of hydraulic piston rods mentioned in the background above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station thermal spraying fixture for hydraulic piston rods, including a frame, a horizontal plate fixed in the middle of the inner wall of the frame, an alternating assembly provided directly above the horizontal plate, and drying assemblies provided at both the front and rear ends of the top of the frame;

[0007] The alternating assembly includes two sets of movable plates slidably connected to the upper end of the inner wall of the frame. A first vertical shaft is rotatably connected inside the movable plate, passing through its upper and lower ends. A first groove is formed in the inner wall of the first vertical shaft. A limit spring is fixed at the top of the inner wall of the first groove. A square plate is fixed at the bottom of the limit spring. A ball-head rod is fixed at the bottom of the square plate. A second vertical shaft passing through the horizontal plate is attached to the bottom of the first vertical shaft. A second groove is formed inside the second vertical shaft. A triangular block is slidably connected to the inner wall of the second groove. A helical spring is fixed at the bottom of the triangular block. A fixing plate is provided at the bottom of the helical spring. A push rod is rotatably connected to the bottom of the fixing plate. The bottom of the push rod passes through the end of the second vertical shaft and is fixed with a long strip. Electric push rods are installed on both sides of the bottom end of the long strip.

[0008] As a preferred technical solution, a servo motor is installed on one side of the frame, and double-groove pulleys are fixed to the output end of the servo motor and the lower end of multiple sets of second vertical shaft curved surfaces. A belt is provided between the multiple sets of double-groove pulleys for transmission, and a three-jaw chuck for clamping the hydraulic piston rod is installed at the top of each of the multiple sets of first vertical shafts.

[0009] As a preferred technical solution, the ball head rod and the square plate are both slidably connected to the first groove, and the end of the ball head rod passes through the bottom end of the first vertical shaft.

[0010] As a preferred technical solution, the top of the triangular block extends through the end of the second vertical shaft, the ball head rod has a groove inside that matches the triangular block, and the top of the second vertical shaft has a circular groove that matches the ball head rod.

[0011] As a preferred technical solution, a circular block is rotatably connected inside the fixed plate, the circular block is fixed to the top rod, and the top rod is slidably connected to the second vertical shaft.

[0012] As a preferred technical solution, the drying assembly includes vertical grooves opened on both sides of the inner wall of the frame at the front and rear ends. A vertical block is slidably connected in the vertical groove. An arc-shaped plate is fixed on one side of the vertical block. Multiple sets of electric fans are installed on the side of the arc-shaped plate near the three-jaw chuck. An inclined plate is fixed on the top of the arc-shaped plate. A condenser pipe is provided on the side of the inclined plate near the electric fan.

[0013] As a preferred technical solution, a support plate is attached to the bottom of the vertical block, the support plate is slidably connected to the frame, and a T-shaped rod is installed on one side of the support plate.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. This utility model uses an electric push rod to disengage the triangular block from the slot, causing the first vertical axis to disengage from the second vertical axis. Then, another set of moving plates is pushed to the designated position, allowing the first and second vertical axes to engage and engage for subsequent spraying operations. By alternating the insertion and removal of the hydraulic piston rod, continuous operation can be achieved, thereby improving the overall spraying efficiency and avoiding the waste of a lot of time due to waiting for the hydraulic piston rod to cool down for a long time.

[0016] 2. This utility model moves the support plate by pulling the T-shaped rod, thereby releasing the support plate from supporting the vertical block. The vertical block then moves the arc plate and inclined plate downward along the vertical groove, making it easier for workers to fix and disassemble the hydraulic piston rod. When a set of hydraulic piston rods is sprayed and the moving plate is moved out, the vertical block rises and is limited by the support plate. Under the action of the condenser pipe and the electric fan, the cooling process of the hydraulic piston rod can be accelerated, reducing material deformation or performance degradation caused by high temperature.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A multi-station thermal spraying fixture for hydraulic piston rods, such as Figure 1-7 As shown, the machine includes a frame 100, a horizontal plate 110 fixed in the middle of the inner wall of the frame 100, an alternating component 200 provided directly above the horizontal plate 110, and drying components 300 provided at the front and rear ends of the top of the frame 100.

[0030] The alternating assembly 200 includes two sets of movable plates 210 slidably connected to the upper end of the inner wall of the frame 100. A first vertical shaft 220 is rotatably connected inside each movable plate 210, passing through its upper and lower ends. A first groove 221 is formed in the inner wall of the first vertical shaft 220. A limit spring 230 is fixed to the top of the inner wall of the first groove 221. A square plate 240 is fixed to the bottom of the limit spring 230. A ball-head rod 250 is fixed to the bottom of the square plate 240. A second vertical shaft 260, passing through the horizontal plate 110, is attached to the bottom of the first vertical shaft 220. The interior of the 60 has a second groove 261, and a triangular block 270 is slidably connected to the inner wall of the second groove 261. A helical spring 280 is fixed to the bottom of the triangular block 270. A fixing plate 290 is provided at the bottom of the helical spring 280. A top rod 2910 is rotatably connected to the bottom of the fixing plate 290. The bottom of the top rod 2910 passes through the end of the second vertical shaft 260 and is fixed with a long strip 2920. Electric push rods 2930 are installed on both sides of the bottom of the long strip 2920. The ball head rod 250 has a slot 251 that matches the triangular block 270.

[0031] After the worker finishes spraying a set of hydraulic piston rods, the electric push rod 2930 is activated to move the strip 2920 downwards. This causes the strip 2920 to move the push rod 2910 synchronously. The push rod 2910, through the round block 2911, causes the fixing plate 290 to slide within the second groove 261. The fixing plate 290 pulls the spiral spring 280 and the triangular block 270 downwards synchronously until the triangular block 270 disengages from the limit of the slot 251. Then, the moving plate 210 is pushed, causing the moving plate 210 to move the sprayed hydraulic piston rods on the first vertical shaft 220 and the three-jaw chuck 150 onto the frame 100. During the sliding process, the ball head rod 250 is forced to push the square plate 240 to compress the limiting spring 230 and move into the first groove 221 until the ball head rod 250 disengages from the circular groove 252, thus disengaging the first vertical shaft 220 from the second vertical shaft 260. Then, another set of moving plates 210 is pushed to the designated position, so that the first vertical shaft 220 and the second vertical shaft 260 are engaged and locked together for subsequent spraying operations. By alternating the movement of the hydraulic piston rods in and out, continuous operation can be achieved, thereby improving the overall spraying efficiency and avoiding the waste of a lot of time due to waiting for the hydraulic piston rods to cool down for a long time.

[0032] Please refer to this carefully. Figures 1 to 3 A servo motor 120 is installed on one side of the frame 100. The output end of the servo motor 120 and the lower end of the curved surface of multiple sets of second vertical shafts 260 are all fixed with double groove pulleys 130. A belt 140 is provided between the multiple sets of double groove pulleys 130 for transmission. A three-jaw chuck 150 for clamping hydraulic piston rods is installed at the top of multiple sets of first vertical shafts 220.

[0033] The operator fixes the hydraulic piston rod with a three-jaw chuck 150, then starts the servo motor 120. Under the action of multiple sets of double-groove pulleys 130 and belts 140, multiple sets of first vertical shafts 220 and second vertical shafts 260 rotate, which in turn causes the three-jaw chuck 150 to drive the hydraulic piston rod to rotate. Then, the surface of the hydraulic piston rod is sprayed with a spray gun.

[0034] Please refer to this carefully. Figures 4 to 6 The ball head rod 250 and the square plate 240 are slidably connected to the first groove 221. The end of the ball head rod 250 passes through the bottom of the first vertical shaft 220, and the top of the triangular block 270 passes through the end of the second vertical shaft 260. The top of the second vertical shaft 260 is provided with a circular groove 252 that matches the ball head rod 250. A circular block 2911 is rotatably connected inside the fixing plate 290. The circular block 2911 is fixed to the top rod 2910, and the top rod 2910 is slidably connected to the second vertical shaft 260.

[0035] By allowing the ball head rod 250 and the square plate 240 to slide in the first groove 221, it is easy for the ball head rod 250 to move into the first groove 221 when it is under force. By setting the round block 2911, it is prevented that the second vertical shaft 260 drives the fixed plate 290 to rotate simultaneously and drive the top rod 2910 to rotate.

[0036] Please refer to this carefully. Figure 2 and Figure 7 The drying assembly 300 includes vertical grooves 311 formed on the front and rear ends of both sides of the inner wall of the frame 100. A vertical block 310 is slidably connected in the vertical groove 311. An arc plate 320 is fixed on one side of the vertical block 310. Multiple sets of electric fans 330 are installed on the side of the arc plate 320 near the three-jaw chuck 150. An inclined plate 340 is fixed at the top of the arc plate 320. A condenser pipe 350 is provided on the side of the inclined plate 340 near the electric fan 330. A support plate 360 ​​is attached to the bottom of the vertical block 310. The support plate 360 ​​is slidably connected to the frame 100. A T-shaped rod 370 is installed on one side of the support plate 360.

[0037] When the movable plate 210 is pushed in or out, the operator pulls the T-shaped rod 370 to move the support plate 360, thereby releasing the support plate 360 ​​from supporting the vertical block 310. This allows the vertical block 310 to move the arc plate 320 and the inclined plate 340 downwards along the vertical groove 311, facilitating the operator to fix and disassemble the hydraulic piston rod. When a set of hydraulic piston rods is sprayed and the movable plate 210 is moved out, the vertical block 310 rises and is limited by the support plate 360. Under the action of the condenser pipe 350 and the electric fan 330, the cooling process of the hydraulic piston rod can be accelerated, reducing material deformation or performance degradation caused by high temperature.

[0038] In use, the hydraulic piston rod is fixed by the three-jaw chuck 150. Then, the servo motor 120 is started to rotate the hydraulic piston rod for spraying. After the operator finishes spraying one set of hydraulic piston rods, the electric push rod 2930 is activated to disengage the triangular block 270 from the limiting position of the slot 251. Then, the moving plate 210 is pushed to disengage the first vertical shaft 220 from the second vertical shaft 260. The other set of moving plates 210 is then pushed to the designated position to engage the first vertical shaft 220 and the second vertical shaft 260 for subsequent spraying operations. By alternately moving the hydraulic piston rods in and out, continuous operation can be achieved, thereby improving the overall spraying efficiency and avoiding the waste of a large amount of material due to long waiting times for the hydraulic piston rods to cool down. During the process of pushing or pushing in the movable plate 210, the operator pulls the T-shaped rod 370 to move the support plate 360, thereby releasing the support plate 360 ​​from supporting the vertical block 310. This allows the vertical block 310 to move the arc plate 320 and the inclined plate 340 downwards along the vertical groove 311, facilitating the fixing and disassembly of the hydraulic piston rod. When a set of hydraulic piston rods is sprayed and the movable plate 210 is moved out, the vertical block 310 rises and is limited by the support plate 360. Under the action of the condenser pipe 350 and the electric fan 330, the cooling process of the hydraulic piston rod can be accelerated, reducing material deformation or performance degradation caused by high temperature. All parts not involved in this device are the same as or can be implemented using existing technology.
