Description

Technical Field

[0001] This utility model belongs to the technical field of valve production and processing equipment, and specifically relates to a spraying device for valve production. Background Technology

[0002] A valve is a key device used in fluid control systems. Its main function is to control the flow direction and flow rate of liquids in various pipelines and equipment. Valves can be classified into various types according to their material, such as cast iron valves, cast steel valves, and stainless steel valves, and according to their actuation method, such as manual valves, electric valves, and pneumatic valves.

[0003] Valve spraying is a common surface treatment technology aimed at improving the corrosion resistance and aesthetics of valves and extending their service life. During the spraying process, the valve is clamped and fixed using clamping tools, and then a spray gun is used manually to spray the valve.

[0004] However, when spraying valves, there is a problem of uneven coating on the valve surface, and human operation also affects the efficiency of valve spraying. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a spraying device for valve production, which can achieve more uniform spraying treatment of valves and higher efficiency in valve spraying treatment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spraying device for valve production includes a worktable. A baffle and a support plate are fixed to the upper surface of the worktable near the left and right sides, respectively. A clamping seat for clamping the workpiece is set at the center of the upper surface of the worktable. The clamping seat can rotate on the worktable. An upward-facing opening slot is provided in the middle part of the support plate. A lifting block that can move up and down is clamped inside the opening slot. A spraying pipe that can be adjusted left and right is inserted horizontally through the upper part of the lifting block. A nozzle is fixed to the left end of the spraying pipe. A lifting mechanism for driving the lifting block to move up and down is fixed to the upper end of the support plate.

[0008] Furthermore, the clamping seat includes a placement plate, on the upper surface of which are mounted two V-shaped clamping blocks that can move relative to each other, and on the lower side of the placement plate is a drive mechanism that drives the two clamping blocks to move relative to each other.

[0009] Furthermore, two guide blocks, one in front and one behind, are fixed to the lower side of the clamping block and pass through the placement plate. The two guide blocks are fixedly connected by a connecting plate, and an adjusting block is fixed to the lower side of the connecting plate.

[0010] Furthermore, the upper surface of the placement plate has two guide openings for guiding the guide blocks, and a fixing block is fixed on the lower side of the placement plate. A rotating shaft is fixed on the lower side of the fixing block, and the lower end of the rotating shaft passes through the worktable and is fixedly connected to a motor.

[0011] Furthermore, the drive mechanism includes two fixed plates, left and right, fixed on the lower side of the placement plate. A bidirectional lead screw is rotatably installed between the two fixed plates, and a drive motor for driving the bidirectional lead screw to rotate is fixed on one side of one of the fixed plates. The bidirectional lead screw passes through the fixed block, and the thread of the bidirectional lead screw passes through the adjusting block.

[0012] Furthermore, the lifting block has slots on both the front and rear sides that engage with the sidewalls of the opening groove, and the upper side of the lifting block is threaded with a locking screw to lock the spray pipe.

[0013] Furthermore, the lifting mechanism includes a fixed seat fixed to the upper end of the support plate, a lifting screw threaded through the lifting block is installed on the fixed seat, and a lifting motor that drives the lifting screw to rotate is fixed on the upper side of the fixed seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When spraying the valve, the valve is clamped and fixed by a clamping seat. When the clamping seat rotates, it drives the valve to rotate, so that the nozzle on the spraying pipe can spray the valve in a circle. At the same time, the lifting mechanism drives the lifting block to move the spraying pipe up and down, so as to carry out a comprehensive spraying treatment on the valve. This makes the spraying treatment of the valve more uniform and has a higher spraying efficiency. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1 As shown, a spraying device for valve production includes a workbench 1. A baffle 2 and a support plate 4 are fixed to the upper surface of the workbench 1 near the left and right sides, respectively. A clamping seat 3 for clamping the workpiece is located at the center of the upper surface of the workbench 1. The clamping seat 3 can rotate on the workbench 1. An upward-facing opening groove is provided in the middle of the support plate 4. A vertically movable lifting block 6 is clamped inside the opening groove. A nozzle is fixed to the left end of the spraying pipe 7. A lifting mechanism 5 for driving the lifting block 6 to move up and down is fixed to the upper end of the support plate 4. When spraying the valve, the valve is clamped and fixed by the clamping seat 3. When the clamping seat 3 rotates, it drives the valve to rotate, thereby achieving a complete spraying of the valve by the nozzle on the spraying pipe 7. Simultaneously, the lifting mechanism 5 drives the lifting block 6 to move the spraying pipe 7 up and down, thereby performing a comprehensive spraying treatment on the valve.

[0027] A spray pipe 7 that can be adjusted left and right is inserted horizontally on the upper part of the lifting block 6. The distance between the nozzle and the valve can be adjusted by adjusting the spray pipe 7 left and right, so as to better ensure the spraying effect.

[0028] like Figure 2 As shown, the clamping seat 3 includes a placement plate 32, and two V-shaped clamping blocks 31 that can move relative to each other are installed on the upper surface of the placement plate 32. The V-shaped clamping blocks 31 can adapt to clamping and fixing valves of different sizes.

[0029] A drive mechanism 33 is fixed on the lower side of the placement plate 32 to drive the two clamping blocks 31 to move relative to each other. The drive mechanism 33 drives the two clamping blocks 31 to move relative to each other, thereby clamping and fixing the valve.

[0030] like Figure 3 As shown, the clamping block 31 has two guide blocks 311 fixed on its lower side, which pass through the placement plate 32. The two guide blocks 311 are fixedly connected by a connecting plate 312. An adjusting block 313 is fixed on the lower side of the connecting plate 312. The clamping block 31 is installed on the placement plate 32 by means of the guide blocks 311 and the connecting plate 312.

[0031] like Figure 4 As shown, the upper surface of the placement plate 32 is provided with two guide openings 321 for guiding the guide block 311. The guide openings 321 guide the guide block 311 on the lower side of the clamping block 31.

[0032] A fixing block 322 is fixed to the lower side of the placement plate 32, and a rotating shaft 323 is fixed to the lower side of the fixing block 322. The lower end of the rotating shaft 323 passes through the worktable 1 and is fixedly connected to a motor. The motor drives the rotating shaft 323 to rotate the fixing block 322 and the placement plate 32.

[0033] like Figure 5 As shown, the drive mechanism 33 includes two fixed plates 333 on the left and right sides fixed to the lower side of the placement plate 32. A bidirectional lead screw 332 is rotatably installed between the two fixed plates 333. A drive motor 331 that drives the bidirectional lead screw 332 to rotate is fixed on one side of one of the fixed plates 333. The bidirectional lead screw 332 is threaded through the adjusting block 313. The drive motor 331 drives the bidirectional lead screw 332 to rotate. The rotation of the bidirectional lead screw 332 drives the adjusting blocks 313 on the left and right clamping blocks 31 to move relative to each other.

[0034] The bidirectional lead screw 332 passes through the fixing block 322, and the fixing block 322 provides support for the middle part of the bidirectional lead screw 332.

[0035] like Figure 6 As shown, the lifting block 6 has slots 61 on both the front and rear sides that are engaged with the side wall of the opening slot. The lifting block 6 is installed in the opening slot and is guided and engaged in the opening slot using the slots 61.

[0036] The upper side of the lifting block 6 is threaded with a locking screw 62 for locking the spray pipe 7. After the spray pipe 7 is adjusted, it is locked and fixed by the locking screw 62.

[0037] like Figure 7 As shown, the lifting mechanism 5 includes a fixed seat 52 fixed to the upper end of the support plate 4. The fixed seat 52 fixes the lifting motor 51 and rotates the lifting screw 53.

[0038] A lifting screw 53 with a thread passing through the lifting block 6 is installed on the fixed base 52. A lifting motor 51 that drives the lifting screw 53 to rotate is fixed on the upper side of the fixed base 52. The lifting motor 51 drives the lifting screw 53 to rotate, and the rotating lifting screw 53 drives the lifting block 6 to adjust its height.

[0039] The working principle of this utility model is as follows: When the valve is sprayed, the valve is placed on the placement plate 32. At this time, the drive motor 331 drives the bidirectional lead screw 332 to rotate. The rotation of the bidirectional lead screw 332 drives the adjusting blocks 313 on the left and right clamping blocks 31 to move relative to each other, so that the clamping blocks 31 on both sides move relative to each other to clamp and fix the valve.

[0040] Then, the motor drives the rotating shaft 323 to rotate the fixed block 322 and the placement plate 32, thereby causing the valve to rotate. At this time, the spraying equipment sprays the valve through the spray pipe 7 and the nozzle. At the same time, the lifting motor 51 drives the lifting screw 53 to rotate. The rotating lifting screw 53 drives the lifting block 6 to move up and down. The lifting block 6 then drives the spray pipe 7 and the nozzle to move up and down to spray the valve.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
