Description

Technical Field

[0001] The invention relates to the technical field of valve manufacturing, and in particular to a valve manufacturing countersinking device and a use method thereof. Background Art

[0002] Valve countersinking is a mechanical processing operation during valve manufacturing or installation. Countersinking mainly processes existing holes to achieve specific shape and size requirements. On valves, it is usually for the purpose of installing bolts and nuts, or to make the connection parts of the valve fit more closely to the sealing surface. Countersinking is usually performed using a countersink drill. Countersink drills generally include cylindrical countersinks, conical countersinks, and end countersinks.

[0003] At present, when using countersinking equipment, there is a lack of cooling and impurity removal mechanism. Usually, in the process of countersinking the valve flange, a large amount of heat is generated due to the high-speed rotation of the countersink drill and cutting into the valve material. It is necessary to promptly draw out and spray coolant for auxiliary cooling and cooling treatment. In addition, a large amount of waste chips are generated, which are easily flushed into the countersink by the flushing of the coolant, not only affecting the subsequent countersinking processing efficiency, but also easily accelerating the wear of the countersink drill, affecting the actual service life. Therefore, a valve manufacturing countersinking equipment and a method of use are proposed, so as to increase the cooling and impurity removal mechanism, and use the synchronous cooling and suction unloading method to reduce the heat and waste chips generated in the countersinking process. The influence on the use effect of the countersink drill can not only improve the countersinking processing quality, but also help to extend the service life of the countersink drill, thereby improving the use effect.

[0022] The top of the telescopic sleeve is connected with a toothed plate by bolts, and the second driven gear is connected with the toothed plate by meshing.

[0023] By adopting the above technical solution, a guide component can be formed. During the feeding process, external air can be drawn into the fixed sleeve for storage by utilizing displacement. While completing the countersinking processing reset action, the gas is ejected to perform auxiliary purging treatment on the countersinking surface of the valve. The toothed plate can utilize the meshing connection to drive the second driven gear and the flap to perform a flipping, clamping and positioning action.

[0024] Specifically, the surface of the table is provided with openings on both sides of the feeding assembly, a screw is installed in the table through a bearing, a corresponding ball slider is sleeved on the outer periphery of the screw, and the bottom of the ball slider is connected to the end of the telescopic rod through a bolt, the top of the ball slider is connected to a connecting rod through a bolt, and one end of the connecting rod is connected to the feeding table through a bolt, and the other side of the table is connected to a servo motor through a bolt, and the servo motor is connected to the screw through a drive shaft;

[0025] A recovery box is arranged at the bottom of the platform in the frame.

[0026] By adopting the above technical solution, the ball slider can drive the feeding table to move back and forth to load and unload materials. At the same time, the ball slider can drive the telescopic rod to move back and forth horizontally to perform suction and compression actions. The opening and the recycling box are convenient for recycling the waste chips and waste liquid generated during the countersinking process.

[0027] Specifically, the specific usage is as follows:

[0028] Step 1: Feeding: The operator places the valve flange upward on the support platform of the feeding table, turns on the servo motor to drive the screw to rotate, and uses the ball slider connecting rod to drive the feeding table to slide to one side to the bottom of the countersinking assembly;

[0029] Step 2: Automatic clamping and positioning: When the first rotating frame slides to the tooth pattern, the first driven gear in meshing connection is rotated to drive the first rotating frame to slowly flip upward until the first rotating frame flips to one side of the valve flange, and the first top plate is at the top of the flange. During the feeding process, the telescopic rod and the telescopic sleeve are driven by the ball slider to slide toward one side of the fixed sleeve in turn, and the second driven gear is driven to rotate by the meshing connection of the tooth plate, so that the flap and the second rotating frame rotate rapidly toward the other side of the valve flange until the second top plate rotates to the top of the valve flange for limiting. The first rotating frame cooperates with the second rotating frame to complete the auxiliary clamping and positioning of the valve during the feeding process;

[0030] Step 3: Countersinking: Turn on the electric push rod to drive the mounting seat to slide downward, and the driving motor drives the countersink drill to rotate to perform countersinking on the flange surface. While the mounting seat slides downward, the guide curved rod and the piston are driven to slide downward, and the coolant pre-stored in the storage cylinder is quickly pressed into the guide cylinder through the liquid inlet. While the countersink drill is performing countersinking, the reset push rod slowly slides upward under the elastic force of the reset spring. The coolant is pushed by the second piston, passes through the guide pipe and the nozzle, and sprays the coolant on the countersink drill for auxiliary cooling treatment;

[0031] Step 4: Suction and recovery of waste chips: After the countersinking process is completed, the electric push rod drives the mounting seat to slide upward for reset, and the guide bent rod and the piston slide upward at the same time. The external air is sucked into the storage cylinder through the suction nozzle, the suction pipe and the air inlet in turn. At the same time, the suction nozzle can use the negative pressure generated by the suction to make the waste residue and waste chips remaining on the surface of the valve flange slide outward until they fall into the recovery box through the opening under the action of their own weight to complete the auxiliary recovery;

[0032] Step 5: Reset and return material: After completing the valve countersinking processing, the servo motor drives the screw to rotate again, and the ball slider drives the feeding table to slide and reset. The meshing limit bar tooth pattern can make the first rotating frame automatically rotate to reset, and under the driving action of the ball slider, the telescopic rod and the telescopic sleeve follow the sliding to reset. During the feeding process, the external gas affected by the sliding of the telescopic sleeve is drawn into one side of the third piston in the fixed sleeve through the first air inlet. When the telescopic sleeve slides and resets, the inhaled gas is ejected to the countersink of the valve surface through the air outlet, inlet, guide groove and air outlet nozzle, and it is purged. While the material is returned and reset, the waste liquid and waste chips remaining on the surface are removed.

[0033] By adopting the above technical scheme, an auxiliary cooling and impurity removal mechanism is added, and the pressure generated by the sliding displacement of the countersinking mechanism and the elastic force are utilized to automatically spray cool the countersink drill for auxiliary cooling treatment. In the process of pulling out the countersink drill, the negative pressure generated by the reset suction action can also be utilized to extract the waste chips remaining on the surface during the countersinking process to the outside, which greatly reduces the impact of the waste chips entering the countersinking hole on subsequent processing. The overall structure is simple and the operation is convenient and flexible, which can not only improve the countersinking processing quality of the valve flange, but also help to extend the service life of the countersink drill.

[0034] Beneficial effects of the present invention:

[0035] The valve manufacturing countersinking equipment and use method described in the present invention can add an auxiliary cooling and impurity removal mechanism through the set table, mounting frame, mounting seat, electric push rod, storage cylinder, guide bent rod, piston, nozzle and guide cylinder, and utilize the pressure generated by the sliding displacement of the countersinking mechanism and the elastic force to automatically spray and cool the countersink drill for auxiliary cooling treatment. In the process of pulling out the countersink drill, the negative pressure generated by the reset suction action can also be utilized to extract the waste chips remaining on the surface during the countersinking process to the outside, which greatly reduces the impact of the waste chips entering the countersinking on subsequent processing. The overall structure is simple and the operation is convenient and flexible, which can not only improve the countersinking processing quality of the valve flange, but also help to extend the service life of the countersink drill.

[0073] When in use, the servo motor drives the screw to rotate, and the ball slider can drive the connecting rod and the feeding table to feed the materials, while driving the telescopic rod and the telescopic sleeve to slide toward the fixed sleeve. Through the opening and the recycling box, the waste chips and waste liquid generated during the countersinking process can be easily recycled.

[0074] Exemplarily, as shown in FIG. 1 , the present invention also includes the following specific methods of use:

[0075] Step 1: Feeding: The operator places the valve flange upward on the support platform of the feeding table, turns on the servo motor to drive the screw to rotate, and uses the ball slider connecting rod to drive the feeding table to slide to one side to the bottom of the countersinking assembly;

[0076] Step 2: Automatic clamping and positioning: When the first rotating frame slides to the tooth pattern, the first driven gear in meshing connection is rotated to drive the first rotating frame to slowly flip upward until the first rotating frame flips to one side of the valve flange, and the first top plate is at the top of the flange. During the feeding process, the telescopic rod and the telescopic sleeve are driven by the ball slider to slide toward one side of the fixed sleeve in turn, and the second driven gear is driven to rotate by the meshing connection of the tooth plate, so that the flap and the second rotating frame rotate rapidly toward the other side of the valve flange until the second top plate rotates to the top of the valve flange for limiting. The first rotating frame cooperates with the second rotating frame to complete the auxiliary clamping and positioning of the valve during the feeding process;

[0077] Step 3: Countersinking: Turn on the electric push rod to drive the mounting seat to slide downward, and the driving motor drives the countersink drill to rotate to perform countersinking on the flange surface. While the mounting seat slides downward, the guide curved rod and the piston are driven to slide downward, and the coolant pre-stored in the storage cylinder is quickly pressed into the guide cylinder through the liquid inlet. While the countersink drill is performing countersinking, the reset push rod slowly slides upward under the elastic force of the reset spring. The coolant is pushed by the second piston, passes through the guide pipe and the nozzle, and sprays the coolant on the countersink drill for auxiliary cooling treatment;

[0078] Step 4: Suction and recovery of waste chips: After the countersinking process is completed, the electric push rod drives the mounting seat to slide upward for reset, and the guide bent rod and the piston slide upward at the same time. The external air is sucked into the storage cylinder through the suction nozzle, the suction pipe and the air inlet in turn. At the same time, the suction nozzle can use the negative pressure generated by the suction to make the waste residue and waste chips remaining on the surface of the valve flange slide outward until they fall into the recovery box through the opening under the action of their own weight to complete the auxiliary recovery;

[0079] Step 5: Reset and return material: After completing the valve countersinking processing, the servo motor drives the screw to rotate again, and the ball slider drives the feeding table to slide and reset. The meshing limit bar tooth pattern can make the first rotating frame automatically rotate to reset, and under the driving action of the ball slider, the telescopic rod and the telescopic sleeve follow the sliding to reset. During the feeding process, the external gas affected by the sliding of the telescopic sleeve is drawn into one side of the third piston in the fixed sleeve through the first air inlet. When the telescopic sleeve slides and resets, the inhaled gas is ejected to the countersink of the valve surface through the air outlet, inlet, guide groove and air outlet nozzle, and it is purged. While the material is returned and reset, the waste liquid and waste chips remaining on the surface are removed.

[0080] When in use, the added auxiliary cooling and impurity removal mechanism utilizes the pressure generated by the sliding displacement of the countersinking mechanism and the elastic force to automatically spray cool the countersink drill for auxiliary cooling treatment. In the process of pulling out the countersink drill, the negative pressure generated by the reset suction action can also be utilized to extract the waste chips remaining on the surface during the countersinking process to the outside, greatly reducing the impact of waste chips entering the countersinking hole on subsequent processing. The overall structure is simple and the operation is convenient and flexible, which can not only improve the countersinking processing quality of the valve flange, but also help to extend the service life of the countersink drill.

[0081] When the present invention is in use, the operator first places the valve flange upward on the support platform 604 of the feeding platform 602, manually starts the servo motor 205 to drive the screw rod 202 to rotate, uses the ball slider 203 to slide horizontally, and the connecting rod 204 drives the feeding platform 602 to slide to one side until it is at the bottom of the countersinking component 4. During this process, when the first rotating frame 605 slides to the tooth pattern 6011, the first driven gear 6053 engaged in the meshing connection can drive the first rotating frame 605 to slowly flip upward until the first rotating frame 605 flips to one side of the valve. At the same time, the first top plate 6052 is at the top of the valve flange. During the feeding process, it is driven by the horizontal displacement of the ball slider 203, and the telescopic rod 90 4 and the telescopic sleeve 902 slide toward the side of the fixed sleeve 901 in turn, and at the same time, the gear plate 10 is meshed and connected to drive the second driven gear 704 to rotate, so that the flap 701 and the second rotating frame 702 rotate rapidly toward the other side of the valve, until the second top plate 703 rotates to the top of the valve flange, and the first rotating frame 605 can be used to cooperate with the second rotating frame 702 to complete the auxiliary clamping and positioning of the valve during the feeding process, and in the process of automatic feeding, driven by the ball slider 203, the telescopic rod 904 and the telescopic sleeve 902 slide toward the side of the fixed sleeve 901 in turn, and a part of the external gas is sucked into the side of the third piston 903 in the fixed sleeve 901 through the first air inlet 906 due to the sliding compression of the telescopic sleeve 902;

[0082] Then, the electric push rod 493 is manually turned on to drive the mounting seat 402 to slide downward, and the driving motor 405 drives the countersink 404 to rotate to perform countersinking on the flange surface. While the mounting seat 402 slides downward, the guide curved rod 407 and the piston 4071 are driven to slide downward, and the coolant pre-stored in the storage cylinder 406 is quickly pressed into the guide cylinder 409 through the liquid inlet 4095. While the countersink 404 performs countersinking, the reset push rod 4091 slowly slides upward under the elastic force of the reset spring 4093, and the coolant is pushed in the second piston 4071. 092 pushes, through the guide pipe 4094 and the nozzle 408, sprays coolant to the countersink 404 for auxiliary cooling treatment. When the countersink processing position of the valve flange needs to be adjusted, the servo motor 205 can drive the screw rod 202 to reverse, and the ball slider 203 resets the feeding table 602 to slide into the protective cover 801. The stepper motor is manually turned on to drive the support table 604 and the valve to rotate, and the screw rod 202 is rotated again. The ball slider 203 connects the rod 204 to drive the feeding table 602 to feed, thereby completing the adjustment of the countersink processing position;

[0083] After the countersinking process is completed, the electric push rod 403 drives the mounting seat 402 to slide upward for reset, and at the same time drives the guide bent rod 407 and the piston 4071 to slide upward, and the external air is sucked into the storage cylinder 406 through the suction nozzle 502, the suction pipe 503 and the air inlet 4062 in sequence. By using the negative pressure generated by the suction, the suction nozzle 502 can make the waste residue and waste chips remaining on the surface of the valve flange slide outward until they fall into the recovery box 101 through the opening 402 under the action of their own weight to complete the auxiliary recovery;

[0084] Finally, the servo motor 205 drives the screw rod 202 to reverse again, and the ball slider 203 and the connecting rod 204 drive the feeding table 602 to slide and reset. The tooth pattern 6011 of the meshing limit strip 601 can make the first rotating frame 605 automatically rotate and reset. Under the horizontal reset movement of the ball slider 203, the telescopic rod 904 and the telescopic sleeve 902 follow the sliding and reset in turn. The gas inhaled during the feeding process is sprayed toward the countersink of the valve surface through the air outlet 907, the inlet 804, the guide groove 802 and the air outlet nozzle 803, and is purged. Therefore, while the material is returned and reset, the waste liquid and waste chips remaining on the surface are removed. The overall structure is simple, the cost is low, and it is easy to operate, and it is more flexible and convenient to use.

9. A valve manufacturing countersinking device and a method of use according to claims 1-8, characterized in that: The specific usage is as follows: Step 1: Feeding: The operator places the valve flange upward on the support platform (604) of the feeding platform (602), turns on the servo motor (205) to drive the screw (202) to rotate, and uses the ball slider (203) and the connecting rod (204) to drive the feeding platform (602) to slide to one side to the bottom of the countersinking assembly (4); Step 2: Automatic clamping and positioning: When the first rotating frame (605) slides to the tooth pattern (6011), the first driven gear (6053) engaged with the first rotating frame (605) is rotated to drive the first rotating frame (605) to slowly flip upward until the first rotating frame (605) flips to one side of the valve flange, and the first top plate (6052) is at the top of the flange. During the feeding process, the telescopic rod (904) and the telescopic sleeve (902) are driven by the ball slider (203) to slide toward the side of the fixed sleeve (901) in turn, and the tooth plate (10) is engaged to drive the second driven gear (704) to rotate, so that the flap (701) and the second rotating frame (702) rotate quickly toward the other side of the valve flange until the second top plate (703) rotates to the top of the valve flange for limiting. The first rotating frame (605) cooperates with the second rotating frame (702) to complete auxiliary clamping and positioning of the valve during the feeding process; Step 3: countersinking: the electric push rod (493) is turned on to drive the mounting seat (402) to slide downward, and the driving motor (405) drives the countersink (404) to rotate to perform countersinking on the flange surface. When the mounting seat (402) slides downward, the guide curved rod (407) and the piston (4071) are driven to slide downward, and the coolant pre-stored in the storage cylinder (406) is quickly pressed into the guide cylinder (409) through the liquid inlet (4095). When the countersink (404) performs countersinking, the reset push rod (4091) slowly slides upward under the elastic force of the reset spring (4093), and the coolant is pushed by the second piston (4092) through the guide tube (4094) and the nozzle (408) to spray the coolant on the countersink (404) for auxiliary cooling treatment; Step 4: Suctioning and recovering waste chips: After the countersinking process is completed, the electric push rod (403) drives the mounting seat (402) to slide upward for resetting, and at the same time, the guide bent rod (407) and the piston (4071) slide upward, and the external air is sucked into the storage cylinder (406) through the suction nozzle (502), the suction pipe (503) and the air inlet (4062) in sequence. At the same time, by using the negative pressure generated by the suction, the suction nozzle (502) can make the waste residue and waste chips remaining on the surface of the valve flange slide outward until they fall into the recovery box (101) through the opening (402) under the action of their own weight to complete the auxiliary recovery; Step 5: Reset and return: After the valve countersinking process is completed, the servo motor (205) drives the screw rod (202) to rotate again, and the ball slider (203) drives the feeding platform (602) to slide and reset. The tooth pattern (6011) of the meshing limit bar (601) can be used to make the first rotating frame (605) automatically rotate and reset. In addition, under the driving action of the ball slider (203), the telescopic rod (904) and the telescopic sleeve (902) follow the sliding movement in sequence. The resetting action is performed. During the feeding process, the external gas is sucked into the side of the third piston (903) in the fixed sleeve (901) through the first air inlet (906) due to the sliding of the telescopic sleeve (902). While the telescopic sleeve (902) slides and resets, the sucked gas is ejected to the countersunk hole on the valve surface through the air outlet (907), the inlet (804), the guide groove (802) and the air outlet nozzle (803), and the valve surface is purged. While the material is returned and reset, the waste liquid and waste chips remaining on the surface are removed.
