Description

Technical Field

[0001] This invention relates to the field of valve shell processing and grinding control technology, and in particular to an electronically controlled adjustment device for a valve shell inner wall grinding machine. Background Technology

[0002] The valve body is a core component of valve equipment. The dimensional accuracy and inner wall smoothness of its internal cavity directly determine the valve's sealing performance, flowability, and service life, and are crucial for ensuring stable valve operation. In the valve body manufacturing process, inner wall grinding is a core precision machining step. Grinding removes burrs, oxide layers, and machining allowances from the valve body's inner wall, thus meeting the precision assembly and usage requirements of the valve body. Currently, the industry still uses a traditional manual-assisted processing method for grinding the inner wall of valve bodies. Existing processes require workers to manually transport the valve body to the grinding station, and after grinding, manually remove the workpiece and replace the material to be processed. The entire process relies on manual loading and unloading. This method has significant drawbacks: manual handling is labor-intensive, inefficient, and time-consuming, severely restricting the overall processing speed of the valve body and resulting in high production costs. Furthermore, existing grinding equipment has limited functionality and cannot simultaneously perform internal dust removal and cooling during the inner wall grinding process. Metal dust generated during grinding accumulates inside the valve body, not only scratching the precision inner wall and affecting machining accuracy, but also causing environmental pollution in the workshop. Furthermore, the high temperatures generated during grinding cannot dissipate quickly enough, easily leading to localized heat deformation of the valve body, further reducing the product yield. Therefore, how to achieve automated loading and unloading, simultaneous dust removal and cooling, and intelligent control during the grinding process of the valve body's inner wall is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing grinding process of the inner wall of the valve body relies on manual loading and unloading, which is inefficient and cannot simultaneously achieve dust removal and cooling during the grinding process, resulting in reduced processing accuracy, environmental pollution and thermal deformation of the valve body.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an electronically controlled adjustment device for a valve body inner wall grinding machine, comprising a central main frame and electronically controlled upper and lower feeding frames installed on both sides of the central main frame. A top side bracket is fixedly installed at the upper edge of the central main frame. A top lifting machine is fixedly installed on the crossbeam at the upper end of the top side bracket. A top angle control disc and an end telescopic machine for installing the grinding machine are provided at the extended end of the top lifting machine. An embedded electronically controlled control disc is installed on the upper surface of the central main frame. A waste material extraction device connected to the inside of the embedded electronically controlled control disc is installed on the inner top surface of the central main frame. A flip-type lateral closing device is movably installed on the outer side of the central main frame.

[0005] Furthermore, the electrically controlled loading and unloading frame includes wall-mounted guide rails fixed on both sides of the central main frame, lifting screws installed on the wall-mounted guide rails, a horizontal support platform threaded onto the lifting screws via internal threaded lifting blocks, and an electrically controlled lifting guide belt installed on the horizontal support platform.

[0006] Furthermore, the electrically controlled lifting guide belt includes a bottom transverse guide rail fixedly installed at the lower end of the horizontal support platform, an embedded transverse lead screw installed inside the bottom transverse guide rail, a horizontal base threaded onto the embedded transverse lead screw, an electrically controlled conveyor belt movably installed above the horizontal base via a bracket, and a control support rod for controlling the angle adjustment of the electrically controlled conveyor belt.

[0007] Furthermore, a top closing cover is installed on the outer side of the extended end of the top lift, and a pressure sensor is installed on the lower surface of the top closing cover.

[0008] Furthermore, the top angle control disc includes an end mounting seat axially mounted on the extended end of the top lift, a bottom mounting frame fixed to the bottom of the end mounting seat, a top angle control disc movably mounted on the side wall of the bottom mounting frame, a longitudinal control worm gear mounted on the side wall of the end mounting seat, and an end worm wheel coaxially fixed with the top angle control disc, wherein the longitudinal control worm gear meshes with the end worm wheel for transmission.

[0009] Furthermore, the end telescopic mechanism is fixedly installed on the side wall of the top angle adjustment disc.

[0010] Furthermore, the waste removal device includes an internal lifting support rod fixed to the inner wall of the central main frame, a bottom lifting closing cover controlled by the internal lifting support rod, a bottom collection box fixed to the bottom of the central main frame, a pull-out filter screen installed inside the bottom collection box, a centrifugal air pump installed at the top of the bottom collection box, and a bottom connecting pipe.

[0011] Furthermore, arc-shaped guide rails are provided on both outer walls of the central main frame. The flip-type lateral closing device is movably installed on the outer side of the arc-shaped guide rail via an arc-shaped slider. An inner motor for controlling the adjustment of the arc-shaped slider is installed on the inner side of the arc-shaped guide rail.

[0012] Furthermore, the flip-type lateral closing device includes an arc-shaped mounting base fixed to the outside of the arc-shaped slider, a flip bracket hinged to the outside of the arc-shaped mounting base, an outer support rod for controlling the flip bracket, and an arc-shaped lateral closing cover fixed to the end of the flip bracket.

[0013] Furthermore, a temperature sensor module is installed inside the arc-shaped lateral closure.

[0014] The beneficial effects of this invention are as follows: By setting up electrically controlled loading and unloading frames and electrically controlled lifting guide belts, the automatic lifting, translation, and loading / unloading of valve shell blanks are realized, significantly reducing manual labor intensity and improving work efficiency; through the cooperation of a flip-type side closing device and a top closing cover, a sealed cavity is formed during the grinding process, effectively preventing metal dust from leaking out and polluting the workshop environment. At the same time, in conjunction with a waste material extraction device, real-time dust removal is achieved, preventing dust from scratching the precision inner wall; through a temperature sensor module, the internal temperature of the valve shell is monitored in real time, and a centrifugal vacuum pump is linked to perform forced air extraction and cooling, preventing the valve shell from local thermal deformation due to high grinding temperatures, ensuring processing accuracy, and realizing fully automated and intelligent valve shell inner wall grinding processing.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] like Figures 1 to 4 As shown, an electrically controlled adjustment device for a valve body inner wall grinding machine according to the present invention includes a central main frame 100 and electrically controlled loading and unloading frames 200 installed on both sides of the central main frame 100. The central main frame 100 is the basic load-bearing structure of the entire device. A top side bracket 110 is fixedly installed at its upper edge, and a top lifting mechanism 300 is fixedly installed on the crossbeam at the upper end of the top side bracket 110. The extended end of the top lifting mechanism 300 is provided with a top angle adjustment disc 310 and an end telescopic mechanism 320 installed on the side wall of the top angle adjustment disc 310. A grinding machine 330 is installed on the end telescopic mechanism 320. An embedded electrically controlled adjustment disc 120 is installed on the upper surface of the central main frame 100. A waste material extraction device connected to the interior of the embedded electrically controlled adjustment disc 120 is installed on the inner top surface of the central main frame 100. A flip-type lateral closing device is movably installed on the outer side of the central main frame 100.

[0023] During the loading and unloading operation, the electrically controlled loading and unloading frame 200 is responsible for automatically conveying the valve body blank to be processed onto the central main frame 100. The electrically controlled loading and unloading frame 200 includes wall-mounted guide rails 210 fixed to the two side walls of the central main frame 100. A lifting screw 220 is installed on the wall-mounted guide rail 210, and an internally threaded lifting block 230 is threaded onto the lifting screw 220. A horizontal support platform 240 is fixedly installed on the internally threaded lifting block 230 and moves up and down along the wall-mounted guide rail 210 as the lifting screw 220 rotates. An electrically controlled lifting guide belt 250 is installed on the horizontal support platform 240. The electrically controlled lifting guide belt 250 includes a bottom horizontal guide rail 251 fixedly installed at the lower end of the horizontal support platform 240. An embedded horizontal screw 252 is installed inside the bottom horizontal guide rail 251, and a horizontal base 253 is threaded onto the embedded horizontal screw 252 and can slide laterally along the bottom horizontal guide rail 251. An electrically controlled conveyor belt 254 is movably mounted above the horizontal base 253 via a bracket. A control strut 255 is used to adjust the tilt angle of the electrically controlled conveyor belt 254. During operation, the electrically controlled conveyor belt 254 transports the valve body blank from the side to above the central main frame 100. The lifting screw 220 raises the valve body blank to a height level with the embedded electrically controlled control panel 120. Then, the embedded transverse screw 252 drives the horizontal base 253 to move horizontally, smoothly transferring the valve body blank onto the embedded electrically controlled control panel 120.

[0024] After the valve body blank to be processed is placed on the embedded electronic control panel 120, the top lifting platform 300 begins to descend, driving the top angle control panel 310 and the end telescopic platform 320 towards the upper port of the valve body blank. The top angle control panel 310 includes an end mounting seat 311 axially fitted onto the extended end of the top lifting platform 300. A bottom side mounting frame 312 is fixed to the bottom of the end mounting seat 311, and the top angle control panel 310 is movably mounted on the side wall of the bottom side mounting frame 312. A longitudinal control worm gear 313 is mounted on the side wall of the end mounting seat 311, and an end worm wheel 314 is coaxially fixed to the top angle control panel 310. The longitudinal control worm gear 313 meshes with the end worm wheel 314 to precisely control the tilt angle of the top angle control panel 310, so that the grinder 330 mounted on the end telescopic platform 320 can be aligned with the area to be ground on the inner wall of the valve body. The end telescopic mechanism 320 is fixedly installed on the side wall of the top angle control disc 310, and can extend and retract axially to control the depth of the grinder 330 into the valve body.

[0025] After the grinder 330 extends into the valve housing, the top lifter 300 continues to descend, pressing the top closing cover 340, which is fitted onto the outside of the extended end of the top lifter 300, against the opening at the upper end of the valve housing, thus achieving a sealed closure at the upper end of the valve housing. A pressure sensor 341 is installed on the lower surface of the top closing cover 340 to detect the contact pressure with the upper port of the valve housing, ensuring a good seal while preventing excessive compression that could damage the valve housing.

[0026] Simultaneously, the flip-type lateral closing device closes the lateral opening on the outer wall of the valve body. Arc-shaped guide rails 410 are provided on both sides of the central main frame 100. The flip-type lateral closing device is movably mounted on the outer side of the arc-shaped guide rails 410 via an arc-shaped slider 420. An inner motor 430 is installed inside the arc-shaped guide rail 410, and an adjusting gear is installed at the output end of the inner motor 430. This adjusting gear meshes with the tooth surface on the inner side of the arc-shaped slider 420. The forward and reverse rotation of the inner motor 430 drives the arc-shaped slider 420 to slide along the arc-shaped guide rail 410, adjusting it to a position corresponding to the lateral opening of the valve body. The flip-type lateral closing device includes an arc-shaped mounting base 440 fixed to the outer side of the arc-shaped slider 420. A flip bracket 450 is hinged to the outer side of the arc-shaped mounting base 440, and an outer support rod 460 connects the arc-shaped mounting base 440 and the flip bracket 450 to control the flip angle of the flip bracket 450. An arc-shaped lateral closure cover 470 is fixed to the end of the flip bracket 450. The inner arc surface of the arc-shaped lateral closure cover 470 conforms to the arc-shaped contour of the outer wall of the valve body. The flip bracket 450 rotates around the hinge point by the extension and retraction of the outer support rod 460, so that the arc-shaped lateral closure cover 470 is accurately pressed against the lateral opening of the outer wall of the valve body, thus completing the sealing closure of the lateral opening of the valve body.

[0027] After sealing the upper end and side openings of the valve housing, air is introduced into the valve housing through an external air pipe to maintain internal air pressure balance. The waste extraction device extracts dust and exhaust gas generated during the grinding process in real time. The waste extraction device includes an internal lifting support rod 610 fixed to the inner wall of the central main frame 100. The internal lifting support rod 610 controls the lifting movement of the bottom lifting closing cover 620, causing the bottom lifting closing cover 620 to rise and close the bottom opening of the valve housing, thus forming a fully enclosed grinding chamber from the top closing cover plate 340, the flip-type side closing device to the bottom lifting closing cover 620. A bottom collection box 630 is fixed to the bottom of the central main frame 100. A pull-out filter screen 640 is installed inside the bottom collection box 630. A centrifugal air pump 650 is installed at the upper end of the bottom collection box 630. The centrifugal air pump 650 is connected to the embedded electronic control panel 120 through a bottom connecting pipe 660. During the grinding process, the centrifugal vacuum pump 650 operates continuously, drawing dust-laden exhaust gas from inside the valve housing into the bottom collection box 630 via the bottom connecting pipe 660. After the dust-laden airflow is filtered by the pull-out filter 640, the dust is trapped in the bottom collection box 630, and the clean gas is discharged. A temperature sensor module 480 is installed inside the arc-shaped lateral closure cover 470 to monitor the temperature changes inside the valve housing in real time. When the temperature sensor module 480 detects that the internal temperature of the valve housing exceeds a set threshold, the control system automatically increases the speed of the centrifugal vacuum pump 650, increases the air flow rate, accelerates heat dissipation and cooling, prevents thermal deformation of the valve housing due to localized high temperatures, and ensures grinding accuracy.

[0028] Throughout the grinding process, the grinding machine 330 rotates at high speed driven by its built-in servo motor. The end telescopic mechanism 320 controls the grinding machine 330 to move axially along the inner wall of the valve body. The top lifting mechanism 300 and the top angle adjustment disc 310 work together to finely adjust the grinding angle through the worm gear 313 and the end worm wheel 314, ensuring that the grinding machine 330 can cover the entire area to be processed on the inner wall of the valve body. The embedded electronic control adjustment disc 120 can drive the valve body to rotate at low speed during the grinding process, which, together with the multi-angle feed of the grinding machine 330, achieves comprehensive grinding of the inner wall.

[0029] After grinding, all actuators automatically reset. The top lifting platform 300 rises, causing the top closing cover 340 and grinding components to detach from the valve body; the outer support rod 460 retracts, causing the flipping bracket 450 to flip outward, and the arc-shaped lateral closing cover 470 to detach from the valve body sidewall; the inner lifting support rod 610 descends, causing the bottom lifting closing cover 620 to reset. The electrically controlled loading and unloading frame 200 starts, and the electrically controlled lifting guide belt 250 drives the horizontal base 253 to move horizontally above the central main frame 100 via the embedded transverse lead screw 252. At the same time, the electrically controlled conveyor belt 254 starts, smoothly conveying the finished grinding valve body away from the central main frame 100 area, completing the unloading operation. The entire device integrates and controls the coordinated operation of each driving component through the embedded electrical control panel 120, realizing fully automated operation from automatic loading, positioning and clamping, sealing and closing, grinding execution, dust removal and cooling to finished product unloading.
