Description

Technical Field

[0001] The present invention relates to the technical field of control valve processing, and particularly relates to a drilling machine and its process for control valve processing and production. Background Art

[0002] A control valve is a key component in an industrial automation system, used to regulate the flow rate and pressure of fluids (such as gases, steam, water, oil, etc.). The quality of the control valve directly affects the performance and safety of the system. Therefore, during the production process of control valves, a drilling machine is a commonly used device, mainly used for processing holes, threaded holes, and other precision components on the valves.

[0003] After retrieval, a drilling machine for control valve processing and production with the authorization announcement number CN217315965U includes a workbench. One side of the top of the workbench is fixedly connected with a fixed block. An installation groove penetrating the fixed block is opened on one side of the fixed block. Tooth plates are fixedly connected to both inner side walls of the installation groove. A work frame is arranged on the other side of the top of the workbench. By precisely adapting and adjusting the equipment, the above drilling machine avoids the operator from working in an uncomfortable posture, thereby improving the working state and increasing production efficiency. However, there are still deficiencies in actual applications. Specifically, when processing irregular control valve bodies, especially when multiple holes with different orientations need to be drilled, the existing design requires re-adjusting the position of the workpiece or replacing the drill bit to meet different drilling requirements. Frequent re-setting of the clamping state of the workpiece not only takes time but also increases the operation difficulty and reduces the overall working efficiency.

Detailed implementation mode

[0027] The technical solution of the present invention will be further described below with reference to the drawings. It should be noted first that in different described embodiments, the same components are provided with the same reference numerals or the same component names, and among them, the disclosed content included in the entire specification can be meaningfully applied to the same components with the same reference numerals or the same component names. The position descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and shown drawings and are meaningfully applied to the new positions when the positions change.

[0028] Example 1: A drill press for processing and producing control valves, as Figures 1-5As shown in the figure, it includes a base 1, which is the assembly carrier of this drill press. A pillar 2 is vertically and fixedly connected to the base 1. A machine housing 3 is fixedly installed at the top of the pillar 2, and a hydraulic cylinder 4 is fixedly assembled at the bottom of the machine housing 3. It also includes a drilling mechanism 5 arranged on the machine housing 3 through the hydraulic cylinder 4, and the drilling mechanism 5 is used for drilling the control valve workpiece. The drilling mechanism 5 includes a mounting disc 51 fixedly installed on the piston rod of the hydraulic cylinder 4. A plurality of groups of mounting blocks 521 are fixedly connected at intervals in the circumferential direction on the top surface of the mounting disc 51. Each mounting block 521 fixedly installs a first motor 52. The output shaft of the first motor 52 rotates downward through the mounting disc 51 and is fixedly assembled with a drive shaft 53. The drive shaft 53 is a multi-joint shaft body that can be bent and changed. A mounting sleeve 54 is fixedly connected to the bottom of the drive shaft 53. The drive shaft 53 is connected and installed with a drill bit 6 through the mounting sleeve 54. The first motor 52 indirectly drives the drill bit 6 through the drive shaft 53, using the drive shaft 53 to expand the adjustable range of the drill bit 6, so that the drill bits 6 on each drive shaft 53 can jointly process intensive drilling. A fixed sleeve 21 is fixedly connected to the lower part of the pillar 2. A first cylinder 7 is fixedly installed on one side of the fixed sleeve 21 of the pillar 2. A sliding sleeve 8 is slidably installed in the middle of the pillar 2. The telescopic rod of the first cylinder 7 is connected to the sliding sleeve 8. An adjusting mechanism 9 for adjusting the drilling angle is arranged on the sliding sleeve 8. The adjusting mechanism 9 includes a mounting ring 91 fixedly connected to the sliding sleeve 8. A plurality of groups of second motors 92 are fixedly installed at intervals in the circumferential direction on the top surface of the mounting ring 91. The number of the second motors 92 is the same as that of the first motors 52. The output shaft of the second motor 92 is fixedly connected with a connecting frame 93. An adjusting part 94 is slidably installed on the connecting frame 93. The adjusting part 94 is connected and adapted to the corresponding drive shaft 53. A second cylinder 95 is fixedly installed on the connecting frame 93. The telescopic rod of the second cylinder 95 is connected to the adjusting part 94 through a connecting block 951. A clamping part 10 for clamping the valve body workpiece is arranged on the fixed sleeve 21. After clamping the valve body workpiece to be drilled through the clamping part 10, the corresponding drill bit 6 is assembled to the bottom of the drive shaft 53 through the mounting sleeve 54. According to the actual opening requirements on the valve body workpiece, the corresponding second motor 92 is selectively enabled to drive the adjusting part 94 on the connecting frame 93 to drive the drive shaft 53 to rotate. Cooperating with the hydraulic cylinder 4 to drive the mounting disc 51 to rise and fall, the node shaft bodies in the entire drive shaft 53 bend adaptively, so that the drill bit 6 assembled on the drive shaft 53 can change the drilling angle. At the same time, the adjusting part 94 can also adjust the drilling position of the drill bit 6 on the drive shaft 53. Cooperating with the hydraulic cylinder 4 and the first cylinder 7 to respectively drive the drilling mechanism 5 and the adjusting mechanism 9 to rise and fall synchronously, the first motor 52 drives the drill bit 6 to rotate through the drive rod, so that the drill bit 6 with the adjusted drilling angle approaches the valve body workpiece on the clamping part 10. Finally, cooperating with the second cylinder 95 to drive the drill bit 6 with the adjusted angle on the drive rod to drill downward through the adjusting part 94, the drilling of various angles on the valve body workpiece is completed.

[0029] As Figures 2-4As shown in the figure, the drive shaft 53 is composed of a first connecting rod 531, a first universal joint 532, a second connecting rod 533 and a second universal joint 534. One end of the first connecting rod 531 is fixedly connected to the output shaft of the corresponding first motor 52. The other end of the first connecting rod 531 is connected to the second connecting rod 533 through the first universal joint 532. The rod end of the second connecting rod 533 away from the first universal joint 532 is connected to the mounting sleeve 54 through the second universal joint 534. Through the mutual cooperation of the first universal joint 532 and the second universal joint 534, the drill bit 6 on the first connecting rod 531, the second connecting rod 533 and the mounting sleeve 54 can bend at various drilling angles, so as to meet the different drilling processing requirements of the valve body workpiece.

[0030] As Figure 2 , Figure 5 and Figure 6 shown, the adjusting member 94 includes an electric slide rail 941 and a guide plate 942. The electric slide rail 941 is slidably assembled on the connecting frame 93. The guide plate 942 is installed on the electric slide rail 941. The guide plate 942 is rotationally matched with the shaft body of the second universal joint 534. The electric slide rail 941 can move the mounting sleeve 54 on the second universal joint 534 through the guide plate 942, so that the drill bit 6 assembled on the mounting sleeve 54 is displaced, thereby changing the drilling position of the drill bit 6.

[0031] As Figure 3 and Figure 4 shown, a docking groove 541 for docking the drill bit 6 is provided on the inner wall of the sleeve of the mounting sleeve 54. The mounting sleeve 54 is made of a magnetically attractive metal material. A magnet 61 is fixedly arranged on the shank of the drill bit 6. The drill bit 6 can be conveniently adsorbed and docked on the mounting sleeve 54 through the magnet 61, and it is convenient to replace drill bits 6 of different sizes on the mounting sleeve 54.

[0032] As Figure 1 , Figure 7 and Figure 8 shown, the clamping member 10 includes a mounting plate 101 fixedly connected to the fixed sleeve 21. A chute 102 is provided in the middle of the top surface of the mounting plate 101. A sliding plate 103 is slidably installed inside the mounting plate 101 through the chute 102. A three-jaw chuck 104 is fixedly assembled on the sliding plate 103. The three-jaw chuck 104 is used to quickly clamp and fix the valve body workpiece to be processed.

[0033] When using this drill press to drill the control valve body, first, the operator places the workpiece of the control valve body to be processed at the center of the three-jaw chuck 104, activates the three-jaw chuck 104 to firmly clamp the placed workpiece, and makes the workpiece clamped at the preset drilling position. After the workpiece clamping is completed, the operator selects a suitable drill bit 6 according to the processing requirements, uses the magnet 61 to adsorb the mounting sleeve 54, so that the drill bit 6 can be quickly installed into the docking groove 541 of the mounting sleeve 54 in a magnetic adsorption manner. The shank of the drill bit 6 and the mounting sleeve 54 are rigidly connected by magnetic adsorption, and the design of the docking groove 541 in the mounting sleeve 54 ensures the effective transmission of power during rotation. Subsequently, the hydraulic cylinder 4 and the first cylinder 7 are activated synchronously. The hydraulic cylinder 4 and the first cylinder 7 respectively drive the drilling mechanism 5 and the adjusting mechanism 9 to descend simultaneously. When the first cylinder 7 drives the sliding sleeve 8 to move along the column to the preset drilling height, the second motor 92 is activated. The second motor 92 drives the connecting frame 93 to rotate, so that the electric slide rail 941 and the guide plate 942 on the connecting frame 93 rotate synchronously. The guide plate 942 synchronously pulls the shaft body of the universal joint to make the drive shaft 53 rotate. The drive shaft 53 makes a controllable bend between the first connecting rod 531 and the second connecting rod 533 through the built-in first universal joint 532 and the second universal joint 534, so as to accurately set the inclination angle of the drill bit 6 on the drive shaft 53. If it is necessary to adjust the horizontal offset of the drilling, the electric slide rail 941 drives the guide plate 942 to change, and the relative coordinates of the tip of the drill bit 6 in the drilling plane of the workpiece are changed through the guide plate 942. Especially for the control valve that requires intensive drilling, since the first motor 52 indirectly transmits power to the drill bit 6 through the drive shaft 53, each drive shaft 53 driven by the first motor 52 can be intensively adjusted, so that the drill bit 6 on the drive shaft 53 can better meet the requirements of intensive drilling on the control valve. When the drilling angle and position of the drill bit 6 are calibrated, the first motor 52 is started. The first motor 52 transmits the rotational power to the drill bit 6 through the drive shaft 53, so that the drill bit 6 rotates at a high speed. At the same time, the second cylinder 95 is activated. The second cylinder 95 drives the electric slide rail 941 and the guide plate 942 to axially press the drive shaft 53 synchronously, thereby pushing the bent drive shaft 53 to drive the drill bit 6 to cut into the surface of the workpiece, and dynamically controlling the downward pressure speed and angle compensation according to the processing depth to ensure the power transmission stability of the bent shaft body under complex forces. Thus, by flexibly adjusting the angle of the drill bit 6 through the drive shaft 53, the drilling of the workpiece at various angles can be completed.

[0034] Embodiment 2: On the basis of Embodiment 1, as Figure 7 and Figure 8As shown in the figure, an electric lead screw 111 is provided at the bottom of the mounting plate 101. The electric lead screw 111 is parallel to the chute 102 on the mounting plate 101. A fixed block 112 is fixedly connected to the bottom surface of the sliding plate 103. The electric lead screw 111 is in threaded cooperation with the fixed block 112. A motor three 113 is fixedly installed on the fixed block 112. The output shaft of the motor three 113 passes through the sliding plate 103 and is connected to the housing of the three-jaw chuck 104. By electrically driving the fixed block 112 and the three-jaw chuck 104 on the sliding plate 103 to slide along the chute 102 of the mounting plate 101 by the electric lead screw 111, the valve body workpiece clamped on the three-jaw chuck 104 can be displaced and adjusted. At the same time, the motor three 113 drives the three-jaw chuck 104 to rotate, so that the valve body workpiece clamped on the three-jaw chuck 104 can also be rotationally adjusted, thereby flexibly adjusting the drilling position of the valve body workpiece.

[0035] As Figure 1 and Figure 9 shown in the figure, a cooling mechanism 12 for providing cooling and lubrication during drilling is provided on the side surface of the mounting plate 101. The cooling mechanism 12 includes a liquid pump 121, a liquid suction pipe 122, a gooseneck pipe 123 and a spray head 124. There are no less than two liquid pumps 121 fixedly installed on the side surface of the mounting plate 101. The liquid inlet of the liquid pump 121 is communicated with the liquid suction pipe 122. A filter head 1221 is provided at the liquid inlet of the liquid suction pipe 122 on the liquid pump 121. The liquid outlet of the liquid pump 121 is communicated with the gooseneck pipe 123. The gooseneck pipe 123 has plasticity. A spray head 124 is installed at the liquid outlet of the gooseneck pipe 123. The angle of the spray head 124 facing the processed valve body workpiece can be flexibly adjusted through the gooseneck pipe 123. Then, the liquid suction pipe 122 is placed into the cutting fluid, and the clean cutting fluid filtered by the filter head 1221 is pumped into the gooseneck pipe 123 by the liquid pump 121 and sprayed onto the valve body workpiece being drilled from the spray head 124, so as to provide cooling and lubrication for the workpiece.

[0036] As Figure 1 and Figure 9 shown in the figure, a collection box 13 is provided at the bottom of the base 1. A raised fence is provided around the collection box 13. The collection box 13 is used for centrally collecting the debris after the valve body workpiece is drilled by the drill press.

[0037] When it is necessary to adjust the drilling position of the workpiece, the electric screw rod 111 at the bottom of the mounting plate 101 can also be started. The rotating electric screw rod 111 drives the fixed block 112 and the sliding plate 103 to horizontally translate along the chute 102 of the mounting plate 101, realizing the horizontal position adjustment of the workpiece. At the same time, the motor three 113 drives the three-jaw chuck 104 to rotate integrally around the vertical axis through the gear set, so that the angle of the workpiece is aligned with the preset drilling direction, enabling this drilling machine to adapt to more complex drilling operations on the workpiece. When processing the workpiece, the cooling mechanism 12 is started synchronously. First, the plastic gooseneck tube 123 is adjusted to the best spraying angle, and the liquid suction pipe 122 is placed into the container of the cutting fluid. Then, the liquid pump 121 is enabled. The liquid pump 121 extracts the cutting fluid through the liquid suction pipe 122. The extracted cutting fluid flows through the filter head 1221 and is filtered by the filter head 1221 and then flows into the liquid suction pipe 122. The filtered cutting fluid flows through the liquid suction pipe 122 and the gooseneck tube 123 in sequence and then continuously jets from the nozzle 124 onto the drilled workpiece, pre-wetting the processing area to reduce the thermal influence, effectively reducing the friction temperature and discharging the debris. The waste chips flow into the bottom collection box 13 along with the liquid to complete the collection, and through the collection box 13, the waste chips and waste liquid can be centrally processed later.

[0038] A drilling process for the processing and production of control valves includes the following steps: S1. First, use the three-jaw chuck 104 to fix the valve body workpiece. According to the specifications and drilling requirements of the to-be-processed control valve body workpiece, select and magnetically install a suitable drill bit 6 onto the drive shaft 53, and adjust the position and angle of the valve body workpiece through the electric screw rod 111 and the motor three 113; S2. Start the hydraulic cylinder 4 and the cylinder one 7 to simultaneously lower the drilling mechanism 5 and the adjustment mechanism 9. According to the specific position requirements of the drilling, use the cylinder one 7 and the motor two 92 to precisely adjust the drilling angle and position. Start the motor one 52 to rotate the drill bit 6, and use the cylinder two 95 to push the drill bit 6 to perform a drilling operation on the valve body workpiece on the three-jaw chuck 104, while using the cooling mechanism 12 to provide cooling and lubrication; S3. After the drilling is completed, the hydraulic cylinder 4 and the cylinder one 7 simultaneously lift the drilling mechanism 5 and the adjustment mechanism 9 back to the initial position, remove the drilled control valve workpiece from the three-jaw chuck 104, and check whether the drilling quality meets the standards to prepare for the processing of the next control valve workpiece. Finally, centrally clean the drill chips in the collection box 13.
