Description

Technical Field

[0001] This utility model relates to the field of vacuum pump body production technology, specifically to a painting equipment for vacuum pump body production and processing. Background Technology

[0002] In the production of vacuum pumps, the pump body, as the basic structural component of the vacuum pump, is related to the performance, reliability and service life of the vacuum pump. During the production process of the pump body, painting is an important surface treatment step, and its main functions include corrosion and rust prevention, aesthetics and marking, as well as protection and wear resistance.

[0003] The prior art (Chinese patent application CN202311371181.4, filed on 2023-10-23) discloses a magnetic pump body painting device, including a support base and a paint spray box placed on the support base. A conveyor belt for conveying the pump body is provided on one side of the support base. Mounting plates are rotatably connected to both sides of the support base. The mounting plates are eccentrically mounted on one side of the pump body with a connecting mechanism for positioning and rotating the pump body. A paint spray pipe is fixedly installed inside the support base. The support mechanism is rotatably installed in the connecting housing on one side of the connecting plate. With the cooperation of the sliding mechanism, when the support mechanism moves into the pump body, it can be controlled to unfold and fix the pump body. After the mounting plate moves the pump body to the spray head side, the motor is started, and the pump body can be fully painted. After painting, the mounting plate can convey the pump body to the conveyor belt. No manual installation, placement, or removal is required, resulting in high work efficiency.

[0004] Although existing technologies can improve the painting efficiency of pump bodies, there are still some shortcomings in the working process. When existing painting equipment sprays paint on the pump body, the paint film on the surface of the pump body is uneven, which affects the quality of the pump body. In addition, traditional painting equipment is usually single-station, and the painting efficiency is low. Utility Model Content

[0005] The purpose of this utility model is to provide a painting equipment for the production and processing of vacuum pump bodies, so as to solve the problems mentioned in the background art, such as uneven paint film on the surface of the pump body and low efficiency caused by single station when spraying the pump body.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a painting equipment for vacuum pump body production and processing, comprising a housing, a worktable inside the housing, a rotating mounting seat rotatably connected to the top surface of the worktable, a clamping assembly on the top of the rotating mounting seat, the clamping assembly acting on the inner wall of the pump body for adjustment and clamping, a first rotating rod fixedly connected to the middle of the bottom of the worktable, a reduction motor fixedly connected to one end of the first rotating rod, and a transmission assembly at the bottom of the worktable acting on the rotating mounting seat to realize the rotation of the pump body.

[0007] As a preferred technical solution of this application, the clamping assembly includes a first annular block fixedly connected to the middle of the top of the rotary mounting base. An adjusting rod is rotatably connected to the inner wall of the first annular block. A second annular block is threadedly connected to the outer wall of the adjusting rod. A limiting plate is provided on one side of the first and second annular blocks. A scissor linkage mechanism is provided between the first and second annular blocks and the limiting plate. A guide rod is slidably installed inside the second annular block.

[0008] As a preferred technical solution of this application, there are four clamping components, and the clamping components are symmetrically distributed about the central axis of the worktable.

[0009] As a preferred technical solution of this application, the bottom of the workbench is provided with a support block, there are two support blocks in total, and a support platform is fixedly connected to the bottom surface of the support block, and the support platform is fixedly connected to the shell.

[0010] As a preferred technical solution of this application, the workbench forms a rotating mechanism with the first rotating rod and the reduction motor.

[0011] As a preferred technical solution of this application, the transmission assembly includes an annular toothed rail fixedly connected to the top of the outer wall of the support block. A gear is meshed with the outer wall of the annular toothed rail, and a second rotating rod is fixedly connected to the inner wall of the gear. The second rotating rod is rotatably connected to the worktable, and the top of the second rotating rod is fixedly connected to the rotating mounting base.

[0012] As a preferred technical solution of this application, the interior of the housing is provided with a painting assembly, which includes a painting pipe. The painting pipe is fixedly connected to the top side of the inner wall of the housing, and the central axis of the painting pipe coincides with the central axis of the workbench. The top of the painting pipe is provided with a paint inlet, and the bottom side of the outer wall of the painting pipe is provided with an atomizing nozzle. The atomizing nozzles are symmetrically distributed about the central axis of the painting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This painting equipment for vacuum pump body production and processing adopts a multi-station synchronous composite motion spraying design. Through the circumferentially symmetrical layout of four clamping components, four pump bodies are painted synchronously, which effectively improves efficiency compared with traditional single-station spraying. Moreover, through the composite motion of revolution and rotation, the pump body achieves coverage without dead angles during the spraying process, reducing the time spent on manual turning or repeated spraying. Furthermore, the pump body rotates once for every revolution, which ensures uniform paint film thickness and avoids local accumulation or missed spraying caused by differences in rotation speed. At the same time, the coordinated operation of multiple atomizing nozzles effectively improves the uniformity of paint spraying. The specific details are as follows:

[0014] 1. When clamping the pump body, the vacuum pump body is sleeved on the outside of the clamping assembly. By rotating the adjusting rod in the forward or reverse direction, the second annular block is constrained by the thread and generates axial displacement, sliding on the outer wall of the guide rod. When the second annular block moves downward along the outer wall of the adjusting rod, the scissor linkage mechanism gradually unfolds, and the inner wall of the pump body is clamped by the limiting plate to prevent the pump body from shifting during the painting process, which would affect the quality of the painting. There are four clamping assemblies in total, which can realize multi-station painting work and simultaneously paint multiple pump bodies efficiently, effectively improving the painting efficiency.

[0015] 2. During the combined motion of the pump body, the reduction motor drives the first rotating rod to rotate, thereby driving the worktable to rotate. The four clamping components revolve around the central axis of the worktable. At the same time, the four gears at the bottom of the worktable mesh with the ring gear, and the gears drive the second rotating rod and the rotating mounting base to rotate, thereby realizing the synchronous rotation of the four clamping components. The gear ratio between the ring gear and the gear is set to 4:1. When the pump body revolves once, it rotates four times, which can ensure that the paint film thickness on the surface of the pump body is more uniform.

[0016] 3. During spray painting, the central axis of the spray pipe coincides with the central axis of the workbench, and the bottom side of the outer wall of the spray pipe is equipped with atomizing nozzles. The atomizing nozzles are symmetrically distributed about the central axis of the spray pipe. The paint is sprayed out evenly through the atomizing nozzles, ensuring that the surface of the pump body obtains a paint film of uniform thickness and complete coverage. All atomizing nozzles work at the same time. The coordinated operation of multiple nozzles significantly shortens the spraying time and ensures the uniformity of spraying, effectively improving the spraying efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a painting equipment for the production and processing of vacuum pump bodies.

[0026] Example 1: To address the issue of uneven paint film on the pump body surface during spray painting, which affects pump quality, and the fact that traditional spray painting equipment is typically single-station and has low painting efficiency, please refer to... Figures 1-5 The pump body includes a housing 1, inside which is a worktable 2. A rotary mounting base 3 is rotatably connected to the top surface of the worktable 2. A clamping assembly 4 is located on the top of the rotary mounting base 3, and the clamping assembly 4 acts to adjust and clamp the pump body's inner wall. A first rotating rod 5 is fixedly connected to the middle of the bottom of the worktable 2, and a reduction motor 6 is fixedly connected to one end of the first rotating rod 5. A transmission assembly 7 is located at the bottom of the worktable 2, and the transmission assembly 7 acts on the rotary mounting base 3 to achieve the rotation of the pump body. Figure 4 As shown, the clamping assembly 4 includes a first annular block 401 fixedly connected to the center of the top of the rotary mounting base 3. An adjusting rod 402 is rotatably connected to the inner wall of the first annular block 401. A second annular block 403 is threadedly connected to the outer wall of the adjusting rod 402. A limiting plate 404 is provided on one side of the first annular block 401 and the second annular block 403. A scissor linkage mechanism is provided between the first annular block 401, the second annular block 403, and the limiting plate 404. A guide rod 405 is slidably installed inside the second annular block 403. Figure 4 As shown, there are four clamping components 4, and the clamping components 4 are symmetrically distributed about the central axis of the worktable 2.

[0027] In use, the vacuum pump body can be sleeved on the outside of the clamping assembly 4. By rotating the handle at the top of the adjusting rod 402, the adjusting rod 402 can be rotated in the forward or reverse direction. The second annular block 403 is constrained by the thread and generates axial displacement. The second annular block 403 slides on the outer wall of the guide rod 405. There are three guide rods 405, and they are symmetrically distributed about the central axis of the second annular block 403. When the second annular block 403 moves downward along the outer wall of the adjusting rod 402, the scissor linkage mechanism on one side of the first annular block 401 and the second annular block 403 gradually unfolds. The scissor linkage mechanism drives the limiting plate 404 to limit and clamp the inner wall of the pump body, so as to prevent the pump body from shifting during the painting process and affecting the painting quality. There are four clamping assemblies 4, and they are symmetrically distributed about the central axis of the worktable 2. Multi-station painting work can be realized, and multiple pump bodies can be painted efficiently at the same time, which effectively improves the painting efficiency.

[0028] Example 2: Figure 3 As shown, the bottom of the workbench 2 is provided with support blocks 9. There are two support blocks 9 in total, and a support platform 10 is fixedly connected to the bottom surface of the support block 9. The support platform 10 is fixedly connected to the housing 1, as shown. Figure 3 As shown, the worktable 2 forms a rotating mechanism with the reduction motor 6 via the first rotating rod 5, as... Figure 5 As shown, the transmission assembly 7 includes an annular gear 701 fixedly connected to the top of the outer wall of the support block 9. A gear 702 is meshed with the outer wall of the annular gear 701. A second rotating rod 703 is fixedly connected to the inner wall of the gear 702. The second rotating rod 703 is rotatably connected to the worktable 2, and the top of the second rotating rod 703 is fixedly connected to the rotating mounting base 3.

[0029] In use, the reduction motor 6 is started, which drives the first rotating rod 5 to rotate, thereby driving the worktable 2 to rotate. When the worktable 2 rotates, it can drive the four clamping components 4 to revolve around the central axis of the worktable 2, so that the painting device can spray paint the pump body evenly. At the same time, there are four gears 702. Through the meshing transmission between the gears 702 and the ring gear 701, the second rotating rod 703 and the rotating mounting base 3 are driven to rotate, thereby realizing the synchronous rotation of the four clamping components 4. The gear ratio between the ring gear 701 and the gears 702 is set to 4:1. When the pump body revolves once, it rotates four times, which can ensure that the paint film thickness on the surface of the pump body is more uniform. In addition, the housing 1 is equipped with heating elements. Using the principle of electrothermal exchange, the heating elements dry multiple pump bodies at the same time, and the synchronous compound movement of the pump bodies makes the drying more uniform.

[0030] Example 3: Figure 6As shown, the interior of the housing 1 is provided with a paint spraying assembly 8, which includes a paint spraying pipe 801. The paint spraying pipe 801 is fixedly connected to the top side of the inner wall of the housing 1, and the central axis of the paint spraying pipe 801 coincides with the central axis of the workbench 2. The top of the paint spraying pipe 801 is provided with a paint inlet 802, and the bottom side of the outer wall of the paint spraying pipe 801 is provided with an atomizing nozzle 803. The atomizing nozzles 803 are symmetrically distributed about the central axis of the paint spraying pipe 801.

[0031] In use, the paint inlet 802 is connected to the gear pump and paint storage tank through the paint supply pipe. The paint supply pipe is equipped with a filter to prevent impurities from clogging the atomizing nozzles 803. The paint is evenly sprayed out through the symmetrically arranged atomizing nozzles 803, thereby ensuring that the pump body surface obtains a paint film of consistent thickness and complete coverage. Moreover, all atomizing nozzles 803 work at the same time. Compared with single nozzle reciprocating spraying, multi-nozzle collaborative operation significantly shortens the spraying time and ensures spraying uniformity, effectively improving the painting efficiency.
