DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Please refer to Figure 1 As shown, the present invention provides a valve flange drilling device, including a drilling platform 100, and also including a feeding station 200, a loading station 300, a drilling station 400 and a unloading station 500 installed on the drilling platform 100; wherein the feeding station 200 is used to receive the flange workpiece outputted from the loading station 300, and transport the flange workpiece to the drilling station 400 for drilling, and finally transport the drilled workpiece to the unloading station 500 for output; The feeding station 200 includes a turntable 201, a material placement trough 202 and an arc-shaped support beam 203; the turntable 201 is rotatably mounted on the drilling platform 100, and a servo motor (shown in the figure but not numbered) is also mounted on the drilling platform 100, the output shaft of the servo motor is connected to the middle of the top of the turntable 201, and the turntable 201 can be controlled to rotate at equal angles through the action of the servo motor (this is a known technology and will not be described in detail); there are multiple material placement troughs 202 distributed equidistantly on the circumference of the turntable 201 and penetrating the thickness of the turntable 201. 02, in this application, six material placement troughs 202 are taken as an example, therefore, the servo motor can control the turntable 201 to rotate 60 degrees clockwise each time; wherein, the material placement trough 202 is used to place the flange workpiece, and the depth of the material placement trough 202 is consistent with the thickness of the flange workpiece; the arc-shaped support beam 203 is fixedly installed in the drilling platform 100, the top end surface of the arc-shaped support beam 203 is slidably fitted with the bottom end surface of the turntable 201, and the arc-shaped support beam 203 is used to support the flange workpiece in the material placement trough 202; wherein, as Figure 2 As shown, one end of the arc-shaped support beam 203 is located below the loading station 300, and the other end is located on one side of the unloading station 500; When working: Figure 2 and Figure 3 As shown, each equal-angle rotation of the turntable 201 can make any material trough 202 located below the loading station 300, so that the flange workpiece in the loading station 300 falls into the material trough 202 and onto the top of the arc-shaped support beam 203 by gravity; like Figure 3 As shown, when the turntable 201 continues to rotate 60 degrees clockwise, the flange workpiece in the material trough 202 can slide on the top surface of the arc support beam 203 and be located directly below the drilling station 400, and cooperate with the drilling station 400 to form a drill hole. The drilling position is as shown in FIG. Fig.10 As shown; like Figure 2 As shown, when the turntable 201 continues to rotate clockwise by 120 degrees, the flange workpiece in the material trough 202 will slide on the top surface of the arc-shaped support beam 203 and then separate from the tail end of the arc-shaped support beam 203, and finally fall by gravity to be output through the unloading station 500; In summary, the setting of the feeding station 200 can send the flange workpiece at the loading station 300 to the drilling station 400 for drilling, and finally send the drilled flange workpiece to the unloading station 500 for output, thereby achieving the effect of automatic loading, drilling and unloading, and improving the work efficiency of flange processing.

[0029] Reference Figure 1 and Figure 3As shown, the loading station 300 includes a connecting plate 301 and a blanking pipe 302; the connecting plate 301 is fixedly mounted on the drilling platform 100; the blanking pipe 302 is a pipe body with openings at both ends, and is arranged vertically and fixedly connected to the connecting plate 301. The operator can stack and place multiple flange workpieces in the blanking pipe 302 in advance, or convey the flange workpieces to the blanking pipe 302 through external conveying equipment (such as a conveyor belt); wherein the bottom end of the blanking pipe 302 is slidably fitted with the top surface of the turntable 201; During operation: the turntable 201 rotates 60 degrees clockwise each time, so that the material placement trough 202 on it can be located directly below the blanking tube 302 (the two are concentric), and the flange workpiece in the blanking tube 302 falls into the material placement trough 202 by gravity, and the flange workpiece in the material placement trough 202 will not fall due to the restriction of the arc-shaped support beam 203 on the material placement trough 202, thereby realizing automatic loading of the flange workpiece; Subsequently, as the turntable 201 rotates clockwise, since the thickness of the flange workpiece is consistent with the depth of the feeding groove 202, after the previous flange workpiece is located in the feeding groove 202 and rotates with the turntable 201, the flange workpiece at the bottom of the blanking tube 302 will be located on the top surface of the turntable 201 due to gravity, until the next feeding groove 202 is located directly below the blanking tube 302, the next flange workpiece can be automatically loaded, and this process is repeated to achieve continuous loading of flange workpieces.

[0030] Reference Figure 1 and Figure 2 As shown, the material unloading station 500 can be specifically located at a position rotated 120 degrees clockwise from the drilling station 400, and the material unloading station 500 includes a material discharge port 501 and a material guide plate 502; the material discharge port 501 is arranged through the side of the drilling platform 100; the material guide plate 502 is installed in the material discharge port 501, and the material guide plate 502 is arranged tilted as a whole, and the higher end is located in the drilling platform 100, and the lower end is located outside the drilling platform 100; During operation: after the turntable 201 transfers the flange workpiece from the loading station 300 to the drilling station 400 for drilling, the turntable 201 continues to rotate clockwise, thereby driving the flange workpiece after drilling to slide on the arc support beam 203. As the turntable 201 continues to rotate, the processed flange workpiece will separate from the arc support beam 203 at the drilling station 400 at a position 120 degrees clockwise, thereby forming an opportunity for falling. The fallen flange workpiece will fall on the guide plate 502 and slide out to the lower end of the guide plate 502 by its own gravity, thereby forming an automatic unloading effect.

[0031] Reference Figure 3 and Figure 4As shown, the drilling station 400 includes an electric push rod 401, a drive box 402 and a drill bit 403; the electric push rod 401 is fixedly connected to the drilling platform 100, and the electric push rod 401 is arranged vertically as a whole, with the output end facing downward; the drive box 402 is installed on the output end of the electric push rod 401; a plurality of drill bits 403 for drilling holes in the flange workpiece are distributed on the circumference of the bottom end of the drive box 402. In this application, four bolt holes need to be drilled in the flange workpiece, so four drill bits 403 are provided. The specific number can be set according to actual processing requirements and is not limited here; a gear drive structure or a separate motor drive for driving the four drill bits 403 to rotate is installed in the drive box 402, which is not shown in the figure and is a well-known technology and will not be repeated; During operation: when the turntable 201 rotates 60 degrees clockwise and transports the flange workpiece at the loading station 300 to the bottom of the drilling station 400, the electric push rod 401 can be actuated so that its output shaft drives the drive box 402 and the drill bit 403 controlled by the drive box 402 to move downward. The downward movement of multiple drill bits 403 can form drill holes in the solid part outside the through-opening of the flange workpiece, thereby forming bolt holes (the formed drill holes / bolt holes are distributed in a circle around the through-opening).

[0032] Reference Figure 4 , Figure 5 and Figure 6 As shown, in order to improve the drilling accuracy of the drill bit 403; for this purpose, the drilling station 400 also includes a positioning member 404; the positioning member 404 includes a slide groove 404a, a slider 404b, a spring 404c and a pressure rod 404d; the outer side of each material feeding groove 202 is circumferentially distributed with a plurality of slide grooves 404a opened on the turntable 201, and each slide groove 404a is connected to the material feeding groove 202; a slider 404b is slidably installed in each slide groove 404a, and the slider 404b is beveled away from the top corner of the material feeding groove 202; a spring 404c connected to the bottom end of the turntable 201 is installed at the bottom of each slider 404b; and pressure rods 404d corresponding to the number of sliders 404b are circumferentially distributed on the side of the driving box 402; It is worth noting that Figure 4 As shown, the length of the pressure rod 404d is greater than the drill bit 403, and the bottom end surface of the pressure rod 404d is located below the drill bit 403; in other words, during the synchronous downward movement of the pressure rod 404d and the drill bit 403, the pressure rod 404d first contacts and drives the slider 404b, and then the drill bit 403 contacts the flange workpiece for processing; During operation: when the flange workpiece is located below the drilling station 400 and the electric push rod 401 controls the drive box 402 and the drill bit 403 to move downward, the multiple pressure rods 404d on the drive box 402 will move downward synchronously, and each pressure rod 404d will first contact and squeeze the corresponding top angle of the slider 404b, so that the slider 404b moves radially toward the material trough 202, and the arrangement of the multiple sliders 404b can form radial movement toward the material trough 202 from different directions, and abut against the side of the flange workpiece, and the arc-shaped support beam 203 can support the bottom end of the flange workpiece; for this reason, the cooperation of the upper structure can realize the pre-clamping and positioning of the flange workpiece, and after this positioning, the flange workpiece is concentric with the material trough 202, so as to improve the accuracy of the distribution position of multiple bolt holes formed after subsequent drilling; Subsequently, the drill bit 403 moves downward to contact the flange workpiece that has been pre-positioned and clamped, and a hole is formed during the continuous downward movement of the drill bit 403, so that the bolt holes formed on the flange workpiece after drilling are arranged equidistantly around the through opening / center circumference of the flange workpiece; Furthermore, after the drilling is completed, the electric push rod 401 can control the drill bit 403 to move up. Since the pressure rod 404d is longer than the drill bit 403, the pressure rod 404d and the slider 404b can always clamp the flange workpiece when the drill bit 403 moves up or the drill bit 403 is separated from the flange workpiece, thereby preventing the flange workpiece from being pulled out with the drill bit 403 moving up. After the pressure rod 404d and the slider 404b are separated from each other, the slider 404b can be pulled into the slide groove 404a by the pulling force of the spring 404c. At this time, the multiple sliders 404b are automatically separated from the side of the flange workpiece, thereby automatically releasing the clamping. At this point, the automatic clamping, positioning, drilling, and automatic unclamping of the flange workpiece are completed, and then the turntable 201 rotates clockwise and drives the processed flange workpiece to rotate to the unloading station 500 for output.

[0033] Reference Figure 6 As shown, a rubber layer is attached to one side of each slider 404b facing the material placement groove 202, and the rubber layer can increase the friction between the slider 404b and the side of the flange workpiece, thereby improving the clamping effect.

[0034] Reference Figure 4As shown, the drilling station 400 further includes a liquid outlet part 405; the liquid outlet part 405 includes a liquid infusion tube 405a and a liquid outlet hose 405b; the liquid infusion tube 405a is vertically installed at the middle of the bottom end of the driving box 402, and the liquid infusion tube 405a is connected to an external liquid supply device (not shown in the figure) to pump the cutting fluid into the liquid infusion tube 405a; the liquid outlet hose 405b is horizontally arranged and connected and installed on the side of the liquid infusion tube 405a, the number of the liquid outlet hoses 405b corresponds to the number of the drill bits 403, and the liquid outlet faces the drill bits 403; During operation: the cutting fluid can flow out naturally from the outlets of the multiple outlet hoses 405b at the same time, and the flowing cutting fluid falls to the position where the flange workpiece is drilled in a parabolic arc state, and cooperates with the drill bit 403 to perform drilling operations, thereby playing a role in lubrication and reducing the temperature generated by drilling, thereby increasing the service life of the drill bit 403; At the same time, there is an annular gap between the clamped flange workpiece and the material storage groove 202, and the cutting fluid and some debris falling on the flange workpiece will fall through the gap to the inner bottom of the drilling platform 100 for temporary storage.

[0035] Reference Figure 4 , Figure 6 and Figure 7 As shown, the liquid outlet member 405 further includes a clamping plate 405c and a notch plate 405d; two clamping plates 405c are provided on the outside of each liquid outlet hose 405b, and the bottom end of the clamping plate 405c is connected to the infusion tube 405a through a torsion spring shaft; wherein the two clamping plates 405c are wrapped around the outside of the liquid outlet hose 405b in an inverted "eight" shape; the notch plate 405d is located directly below the drilling station 400, and the notch plate 405d is fixedly connected to the drilling platform 100 through a vertical rod; wherein the number of notch plates 405d corresponds to the liquid outlet hose 405b; During operation: the electric push rod 401 drives the driving box 402, the drill bit 403 and the pressure rod 404d to move downward. After the drill bit 403 moves downward and passes through the flange workpiece, the drill bit 403 part will be located below the turntable 201, and the infusion tube 405a, the liquid outlet hose 405b and the clamping plate 405c will also move downward with the driving box 402. At this time, the infusion tube 405a, the liquid outlet hose 405b and the clamping plate 405c will pass through the opening in the middle of the flange workpiece and be located below the flange workpiece. As the infusion tube 405a continues to move downward, the clamping plate 405c will be driven to contact and squeeze the corresponding notch plate 405d. After the two clamping plates 405c are forced to be squeezed by the notch plate 405d, the two clamping plates 405c can rotate towards each other with the torsion spring axis at the bottom of themselves as the rotation axis. After the two clamping plates 405c rotate towards each other, they will clamp the mouth of the liquid outlet hose 405b, so that the mouth of the liquid outlet hose 405b tends to be flat from a round state. See Fig. 9 As shown; However, if Figure 8As shown, when the outlet hose 405b becomes flat, on the one hand, the spraying area of ​​the cutting fluid output by the outlet hose 405b becomes larger, so that the cutting fluid can be sprayed onto all surfaces of the drill bit 403 located below the flange workpiece, thereby comprehensively cleaning the surface of the drill bit 403 to remove metal debris attached to the surface of the drill bit 403, thereby improving the subsequent processing accuracy and service life of the drill bit 403; on the other hand, the cross-sectional area of ​​the outlet hose 405b becomes smaller after being flattened. At this time, the flow rate of the cutting fluid output from the outlet hose 405b is accelerated, the pressure is greater, and the cutting fluid can be sprayed farther, thereby increasing the cleaning intensity of the surface of the drill bit 403, and further improving the cleaning effect of the attachments on the surface of the drill bit 403.

[0036] Reference Figure 3 and Figure 1 As shown, the drilling station 400 further includes a cleaning member 406; the cleaning member 406 includes a guide port 406a; both sides of each material placement trough 202 are provided with a guide port 406a, and the guide port 406a is formed through the thickness of the rotating disk 201; During operation: During the drilling process, the cutting fluid and metal debris falling on the turntable 201 will also fall into the inner bottom of the drilling platform 100 through the outlet 406a, so as to collect the cutting fluid and debris, reduce the difficulty of subsequent cleaning, and ensure that the surface of the turntable 201 is clean.

[0037] Reference Figure 3 and Figure 1 As shown, the cleaning member 406 also includes a scraper 406b; the drilling platform 100 is also equipped with a scraper 406b that fits the top surface of the turntable 201; the scraper 406b is located between the drilling station 400 and the unloading station 500; During operation: during the drilling process, metal debris will fall on the turntable 201 near the drilling station 400. After the drilling is completed, the turntable 201 needs to rotate clockwise. At this time, the top surface of the turntable 201 will continue to contact the scraper 406b, and the metal debris on the top of the turntable 201 will be blocked by the scraper 406b. As the turntable 201 rotates clockwise, the scraper 406b can scrape the metal debris on the top surface of the turntable 201 into the outlet 406a, and fall into the drilling platform 100 for collection.
