Description

Technical Field

[0001] This invention belongs to the field of pressure transmitter processing technology, specifically relating to a pressure transmitter housing processing equipment. Background Technology

[0002] Pressure transmitters are field instruments in the instrumentation industry, primarily used to measure the pressure of fluids or vacuum. Therefore, they are widely used in industries such as manufacturing, petroleum and chemical, power, coal mining, coal chemical, automotive electronics, aerospace, shipbuilding, healthcare, and the Internet of Things. The requirements for pressure transmitters vary depending on the application environment. Therefore, the manufacturing process for pressure transmitters is typically tailored to the most stringent environmental requirements. For example, when using pressure transmitters in the marine industry, to reduce seawater corrosion of the transmitter housing, the surface is often first ground and then coated with an anti-corrosion coating. However, as shown in Figure 1, the existing pressure transmitter housing surfaces are mainly irregular arc-shaped structures. This can lead to uneven processing and poor accuracy during the existing grinding or coating processes, making it difficult to meet the actual usage requirements of the pressure transmitter. Summary of the Invention

[0003] In view of this, in order to solve the problems mentioned in the background art, the object of the present invention is to provide a pressure transmitter housing processing equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A pressure transmitter housing processing device includes a clamping mechanism for clamping the pressure transmitter housing, a moving mechanism, and an actuator driven by the moving mechanism for processing the pressure transmitter housing.

[0006] The implementing mechanism includes:

[0007] A central column, wherein an electric push rod is fixedly installed at the center of the central column, and the telescopic bottom end of the electric push rod is rotatably connected to a mounting bracket located below the central column;

[0008] A lifting ring is coaxially sleeved on the outside of the central column, and a rotating ring is rotatably connected to the outside of the lifting ring, and a connecting frame is rotatably connected to the bottom of the rotating ring;

[0009] A drive assembly is mounted on a central column and connected to a lifting ring and a rotating ring. The drive assembly includes a lifting drive part for driving the lifting ring to rise and fall and a rotation drive part for driving the rotating ring to rotate.

[0010] The processing head, the mounting bracket and the connecting bracket are both rotatably connected to the processing head.

[0011] In this invention, the position and orientation of the processing head can be flexibly adjusted through structures such as electric push rods, lifting rings, rotating rings, connecting frames, and mounting frames. During the grinding or spraying process of the pressure transmitter housing, the central axis of the processing head can always be perpendicular to the arc-shaped outer surface of the pressure transmitter housing, and the distance between the processing head and the outer surface of the pressure transmitter housing can be kept constant. This effectively improves the stability and uniformity of the processing head, thereby improving the processing quality of the pressure transmitter housing.

[0012] Specifically, the lifting ring and rotating ring can be raised and lowered separately to drive the connecting frame to rotate in linkage, thereby effectively changing the degree of tilt of the processing head in the vertical direction.

[0013] Specifically, the synchronous cooperation between the electric push rod and the lifting ring can drive the mounting frame and the connecting frame to move up and down synchronously, thereby effectively changing the positioning height of the processing head in the vertical direction.

[0014] Specifically, the individual rotation of the rotating ring can drive the connecting frame to rotate around the central column. In conjunction with the rotational connection between the mounting frame and the electric push rod, the positioning angle of the processing head in the horizontal direction can be effectively changed.

[0015] Preferably, the lifting drive portion of the drive assembly includes:

[0016] A fixed platform is fixed to the outer wall of the central column;

[0017] A lifting rack is slidably mounted on the fixed platform, and the bottom of the lifting rack is fixedly connected to the lifting ring;

[0018] A lifting gear is rotatably mounted on the fixed platform, and the lifting gear is meshed with one side of the lifting rack.

[0019] Preferably, the rotation drive portion of the drive assembly includes:

[0020] A rotating toothed ring fixedly connected to the rotating ring;

[0021] A rotating gear mounted on the lifting rack is rotated, and the rotating gear meshes with the rotating gear ring.

[0022] Preferably, the swivel ring and the rotating toothed ring are fixedly connected by support rods, and N support rods are evenly arranged around the central column, with the support rods located on the outside of the fixed platform.

[0023] Preferably, a drive shaft is rotatably mounted on the fixed platform, and a bevel gear set is connected between the drive shaft and the rotating gear for transmission.

[0024] Preferably, the bevel gear set includes two meshing bevel gears connected by an L-shaped connecting frame, and the two bevel gears are fixed coaxially with the drive shaft and the rotating gear, respectively.

[0025] In this invention, a structure consisting of a lifting gear, a lifting rack, a rotating gear ring, a rotating gear, and a drive shaft that cooperate with each other is used to achieve the lifting and rotation of the rotating ring. The structure is simple and ensures that the driving devices of the lifting gear and the drive shaft can be fixedly installed on the central column, thereby reducing the driving difficulty of the overall structure.

[0026] Specifically, the lifting gear and the lifting rack mesh with each other, thereby enabling the lifting rack, lifting ring and rotating ring to rise and fall under the rotational drive of the lifting gear;

[0027] Specifically, the drive shaft is connected to a rotating gear transmission, the rotating gear meshes with a rotating gear ring, and the rotating gear ring is fixed to the swivel ring. Thus, the rotating gear ring and the swivel ring can rotate under the rotation drive of the drive shaft.

[0028] Preferably, the processing head includes a main frame and a processing part. The mounting frame and the connecting frame are rotatably connected to the main frame. The processing part is installed at one end of the main frame and is a spray gun or a grinding head.

[0029] Preferably, the moving mechanism includes an X-axis moving component and a Y-axis moving component mounted on the X-axis moving component, and the central column is mounted on the Y-axis moving component.

[0030] Preferably, the clamping mechanism includes two clamping cylinders arranged symmetrically, and each of the two clamping cylinders has a clamping plate fixed to one end facing the other.

[0031] Preferably, the clamping mechanism further includes two turntables that rotate around the X-axis or the Y-axis, and two clamping cylinders are respectively fixed on the two turntables. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] As shown in Figure 1, the pressure transmitter housing processing equipment provided by the present invention mainly includes a clamping mechanism 100 for clamping the pressure transmitter housing, a moving mechanism 200, and an actuator 300 driven by the moving mechanism 200 for processing the pressure transmitter housing.

[0043] Referring to Figure 1, both the clamping mechanism 100 and the moving mechanism 200 are mounted on the frame. The frame specifically includes four uprights, with two uprights forming a group, and each group of uprights has a mounting plate fixed on it.

[0044] The clamping mechanism 100 includes a turntable rotatably mounted on a mounting plate, such that two turntables are symmetrically arranged, and both turntables are capable of rotating about the X-axis or the Y-axis (the structure shown in Figure 1 is an example of a turntable).

[0045] (The discs rotate around the Y-axis). A clamping cylinder is fixedly installed at the center of each of the two turntables, and a clamping plate is fixed to the opposite end of each cylinder. The extension and retraction of the clamping cylinders allows the pressure transmitter housing to be processed to be clamped between the two clamping plates. The rotation of the turntables allows for adjustment of the clamping angle of the pressure transmitter housing. Regarding the rotation of the turntables, as shown in Figure 1, the turntables can be configured as geared discs, with a gear shaft rotatably mounted between the two mounting plates. The gear shaft can be driven to rotate by a motor, meshing with the bottom of the geared disc. Thus, when the motor drives the gear shaft to rotate, it drives the geared disc and the entire clamped pressure transmitter housing to rotate.

[0046] The moving mechanism 200 includes an X-axis moving component and a Y-axis moving component mounted on the X-axis moving component, and the actuator 300 is mounted on the Y-axis moving component. In Figure 1, the X-axis moving component specifically includes two linear motor assemblies (including linear motor guides and linear motor sliders), wherein the two linear motor guides are respectively fixed on two sets of uprights, and the Y-axis moving component is mounted between the two linear motor sliders. Thus, when the linear motor sliders move along the linear motor guides, the entire actuator 300 and the Y-axis moving component can move along the X-axis. In Figure 1, the Y-axis moving component specifically includes a rotatable lead screw (which can be driven by a motor to rotate) and a guide rod. The lead screw helically passes through the central column 301 in the actuator 300, and the guide rod slides with the central column 301. Thus, the movement of the entire actuator 300 in the Y-axis direction can be achieved by the helical transmission between the lead screw and the central column 301. The X-axis movement and Y-axis movement work together to drive the actuator 300 to any position in the plane, thus facilitating flexible machining of the pressure transmitter housing.

[0047] Execution agency 300 (reference) Figure 2 to Figure 7 As shown, the structure includes a central column 301, a lifting ring 304, a drive assembly, and a processing head 307.

[0048] An electric push rod 302 is fixedly installed at the center of the central column 301, and the telescopic bottom end of the electric push rod 302 is rotatably connected to a mounting frame 303 located below the central column 301, so that the mounting frame 303 can both rise and fall and rotate around the central axis of the central column 301.

[0049] The lifting ring 304 is coaxially sleeved on the outside of the central column 301, and a rotating ring 305 is rotatably connected to the outer side of the lifting ring 304. A connecting bracket 306 is rotatably connected to the bottom of the rotating ring 305. Specifically, the rotating ring 305...

[0050] It can rotate around the central axis of the central column 301, and the rotation center axis at the connection between the connecting frame 306 and the rotating ring 305 is perpendicular to the central axis of the central column 301.

[0051] The aforementioned mounting bracket 303 and connecting bracket 306 are rotatably connected to the processing head 307, as shown in Figure 1. The rotation axes between the mounting bracket 303, connecting bracket 306 and processing head 307 are all horizontal.

[0052] The drive assembly includes a lifting drive section and a rotation drive section. Specifically:

[0053] The lifting drive unit includes a fixed platform 308 fixed to the outer wall of the central column 301. Figure 2 In this design, three fixed platforms 308 are evenly arranged around the central axis of the central column 301. A lifting rack 310 is slidably mounted on each fixed platform 308, and the bottom of the lifting rack 310 is fixedly connected to a lifting ring 304. A lifting gear 309 is also rotatably mounted on each fixed platform 308, and the lifting gear 309 meshes with one side of the lifting rack 310. Furthermore, a motor for driving the lifting gear 309 can be fixedly mounted on the fixed platform 308, thereby driving the lifting rack 310 and the lifting ring 304 to rise and fall through the active rotation of the lifting gear 309. When the lifting ring 304 descends, the rotating ring 305 and its bottom-connected connecting frame 306 descend synchronously, thereby causing one end of the processing head 307 to descend (see reference). Figure 8 (as shown in Figure 10), thereby changing the machining angle of the machining head 307. Conversely, when the lifting ring 304 rises, the machining angle shown in Figure 10 can be changed. Figure 8 The changes.

[0054] In addition, when the electric push rod 302 extends and retracts synchronously with the lifting rack 310, the mounting bracket 303 can also rise and fall synchronously with the lifting ring 304, thereby adjusting the working height of the machining head 307 while ensuring that the current angle of the machining head 307 remains unchanged.

[0055] The rotary drive section includes a rotary gear ring 311 fixedly connected to the rotating ring 305. As shown in the diagram, the rotary gear ring 311 is specifically positioned above the rotating ring 305, and N support rods are evenly fixed between the rotating ring 305 and the rotary gear ring 311. The support rods are located outside the fixed platform 308, thus achieving the fixation between the rotating ring 305 and the rotary gear ring 311. A rotary gear 312 is meshed with the top of the rotary gear ring 311. Specifically, the rotary gear 312 is rotatably mounted on the lifting rack 310. Therefore, when the rotary gear 312 rotates, it drives the rotary gear ring 311 and the rotating ring 305 to rotate. After the rotating ring 305 rotates, it drives the connecting frame 306 and one end of the processing head 307 to rotate, thereby achieving…

[0056] Figure 1 and Figure 8 Rotational changes.

[0057] In addition, regarding the rotation drive of the rotating gear 312, a drive shaft 313 is rotatably mounted on the fixed platform 308, and a bevel gear set is connected between the drive shaft 313 and the rotating gear 312. The bevel gear set includes two meshing bevel gears, which are connected by an L-shaped connecting frame, and the two bevel gears are coaxially fixed with the drive shaft 313 and the rotating gear 312 respectively.

[0058] In summary, the complete principle for realizing the movement of the processing head 307 shown in Figures 1, 8 to 10 is as follows:

[0059] A motor (mounted on a fixed table 308) connected to the lifting gear 309 drives the lifting gear 309 to rotate, thereby enabling the machining head 307 to achieve... Figure 8 The motion changes shown in Figures 9 and 10;

[0060] The drive shaft 313 is driven to rotate by a motor (mounted on the fixed table 308) connected to the drive shaft 313. The central axis of the drive shaft 313 is parallel to the central axis of the central column 301. In this way, the rotating gear 312 is driven to rotate through the bevel gear set, thereby enabling the machining head 307 to achieve the motion changes shown in Figures 1 and 8.

[0061] By combining the aforementioned lifting and rotational changes, the processing head 307 can be positioned in any direction, at any height, and at any angle, thereby greatly improving its processing flexibility. In actual processing, the processing head 307 includes a main frame and a processing part. The mounting bracket 303 and the connecting bracket 306 are both rotatably connected to the main frame. The processing part is installed at one end of the main frame and can be either a spray gun or a grinding head, thus enabling surface grinding or anti-corrosion coating of the pressure transmitter housing according to specific needs. When the processing part is selected as a grinding head, a grinding motor capable of driving the grinding head to rotate should be installed inside the main frame.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
