Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically to a synchronous drilling device for processing flange mounting holes. Background Technology

[0002] A flange is a connecting component used between shafts or between pipe ends. It is a commonly used connecting component in existing machinery. When processing a flange, drilling equipment is required to drill holes in it to ensure its normal function.

[0003] According to the search, the Chinese patent "A Synchronous Drilling Device for Flange Processing" authorized announcement number "CN221582066 U" solves the problem of only being able to drill a single hole in a flange and not being able to drill simultaneously, thus reducing the speed and efficiency of flange drilling by setting a synchronous drilling structure. During drilling, the operator controls the clamping cylinder to make the clamping seat move relative to the force, thereby clamping and fixing the flange.

[0004] Although the above application can fix the flange by drilling, when the flange is fixed by using multiple clamping cylinders to push the mounting bracket, the center of the flange is prone to deviate from the center point of the drilling mechanism, which will affect the accuracy of drilling the flange mounting hole.

[0005] Based on this, this utility model designs a synchronous drilling device for processing flange mounting holes to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a synchronous drilling device for processing flange mounting holes.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A synchronous drilling device for machining flange mounting holes includes a mounting frame. A first electric push rod is mounted on the top of the mounting frame, a sliding plate is mounted on the bottom of the first electric push rod, and a drilling mechanism is mounted on the bottom of the sliding plate. The device also includes a fixing mechanism, which includes a mounting plate fixedly connected to the inner wall of the mounting frame. A plurality of arc-shaped limiting rods are slidably connected to the top of the mounting plate. A support plate is fixedly connected to one side of each limiting rod, and a fixing plate is slidably connected to the upper end of one side of each limiting rod. A second electric push rod is fixedly connected to the bottom of the mounting plate, and a flat-topped conical block is fixedly connected to the top of the second electric push rod. The bottom end of the limiting rod penetrates the mounting plate and abuts against the top of the flat-topped conical block.

[0009] Furthermore, the fixing mechanism also includes a third electric push rod fixedly connected to the top of the mounting plate. A circular block is fixedly connected to the bottom end of the third electric push rod. An installation rod is fixedly connected to one side of the fixing plate. The other end of the installation rod passes through the limiting rod and is fixedly connected to a telescopic rod. The other end of the telescopic rod is fixedly connected to the surface of the circular block.

[0010] Furthermore, a limiting plate is slidably connected to the inner wall of the support plate, and a threaded sleeve is rotatably connected to the other end of the support plate. A lead screw is threadedly connected to the inner wall of the threaded sleeve, and one end of the lead screw passes through the support plate and is fixedly connected to one side of the limiting plate.

[0011] Furthermore, the surface of the flat-topped cone block is fixedly connected with multiple circular rods arranged in a ring. The number and position of the circular rods correspond one-to-one with the number and position of the limiting rods. The lower end of the inner wall of the limiting rod is slidably connected to the surface of the corresponding circular rod.

[0012] Furthermore, a rubber pad is fixedly connected to the bottom end of the fixing plate and the other end of the limiting plate, and the surface of the rubber pad is provided with multiple evenly distributed grooves.

[0013] Furthermore, a corrugated sleeve is fixedly connected to one side of the inner wall of the support plate, and the other end of the corrugated sleeve is fixedly connected to one side of the limiting plate.

[0014] Furthermore, the inner wall of the mounting plate is provided with multiple annularly distributed sliding grooves, and the top and bottom openings of the sliding grooves are both funnel-shaped.

[0015] Furthermore, a limiting block is fixedly connected to the lower end of the surface of the limiting rod, and the surface of the limiting block is slidably connected to the inner wall of the mounting plate. Beneficial effects

[0016] In this design, the fixing mechanism uses multiple limiting rods arranged in a ring around the center of the large gear in the drilling mechanism. Under the action of the second electric push rod and the flat-top cone block, the multiple limiting rods move horizontally simultaneously to fix the flange. This ensures that the distance between the center of the flange and the center points of the multiple limiting rods is the same after the flange is fixed, thus aligning the center of the flange with the center of the large gear in the drilling mechanism. This guarantees that the distance between the multiple drill bits and the center of the flange is the same after the flange is fixed, avoiding errors during drilling. Furthermore, the interaction between the support plate and the corresponding fixing plate ensures the fixing effect of the flange and improves the drilling accuracy of the flange.

[0017] The setting of the limit plate, by utilizing the force exerted by the limit plate when it is fixed and the force exerted by the limit rod when it is fixed, helps to enhance the stability of the flange during the drilling process. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A synchronous drilling device for processing flange mounting holes includes a mounting frame 100. A first electric push rod 200 is mounted on the top of the mounting frame 100, a sliding plate 300 is mounted on the bottom of the first electric push rod 200, and a drilling mechanism 400 is mounted on the bottom of the sliding plate 300. The device also includes a fixing mechanism 500, which includes a mounting plate 510 fixedly connected to the inner wall of the mounting frame 100. A plurality of arc-shaped limiting rods 520 are slidably connected to the top of the mounting plate 510. A support plate 530 is fixedly connected to one side of the limiting rod 520, and a fixing plate 560 is slidably connected to the upper end of one side of the limiting rod 520. A second electric push rod 540 is fixedly connected to the bottom of the mounting plate 510, and a flat-topped cone 550 is fixedly connected to the top of the second electric push rod 540. The bottom end of the limiting rod 520 passes through the mounting plate 510 and fits against the top of the flat-topped cone 550.

[0029] In this embodiment of the utility model, the drilling mechanism 400 includes a circular plate and a motor fixedly connected to the top of the slide plate 300. The bottom end of the motor output shaft passes through the slide plate 300, and a clamping plate is fixedly connected to the lower end of the surface of the motor output shaft. A large gear is rotatably connected to the bottom end of the circular plate, and multiple small gears arranged in a ring are meshed on the surface of the large gear. A drill bit is fixedly connected to the bottom end of the small gears. A groove matching the motor output shaft and the clamping plate is opened at the top end of the gear rotation shaft. In use, the circular plate and the slide plate 300 are installed by bolts and nuts. At this time, the motor output shaft and the clamping plate will enter the groove of the large gear rotation shaft. After installation, the center of the large gear coincides with the center of the motor. (See reference...) Figure 1 and Figure 5 When drilling a flange, the controller starts the first electric push rod 200 to push the slide plate 300 downward and simultaneously drive the drilling mechanism 400 downward. At the same time, the controller starts the motor, and the output shaft of the motor drives the large gear to rotate under the action of the clamp and the groove, thereby driving multiple small gears to rotate synchronously. The small gears drive the drill bit to rotate to perform drilling operations.

[0030] It should be noted that when using this device, a matching circular plate and corresponding large and small gears can be selected according to the flange of different diameters. The installation method of circular plates of different sizes is the same as described above. After the drilling mechanism 400 is installed, the fixing plate 560 and support plate 530 in the fixing mechanism 500 are staggered with the drill bit in the drilling mechanism 400. The fixing mechanism 500 does not affect the drilling operation.

[0031] After the drilling mechanism 400 is installed, the center of the flat-top cone 550 in the fixing mechanism 500 coincides with the center of the large gear, and when the device is in the initial state, the distance between the center point of the multiple limit rods 520 and the center of the flat-top cone 550 is the same.

[0032] When the device is in use, the drilling mechanism 400 is installed and the flange is placed on top of multiple support plates 530. At this time, the upper surface of multiple limit rods 520 is placed inside the through hole in the middle of the flange. The controller starts the second electric push rod 540 to push the flat-top cone block 550 upward. At this time, under the action of the inclined surface of the flat-top cone block 550, multiple limit rods 520 will be squeezed to move horizontally. During the horizontal movement of the limit rods 520, they will contact the inner edge of the flange and adjust the position of the flange. When multiple limit rods 520 can no longer move, one side of multiple limit rods 520 will contact the inner edge of the flange. At this time, the center of the flange coincides with the center of the large gear in the drilling mechanism 400, and the distance between multiple drill bits and the center of the flange is the same.

[0033] In this embodiment of the utility model, multiple limiting rods 520 are arranged in a ring around the center of the large gear in the drilling mechanism 400. Under the action of the second electric push rod 540 and the flat-top cone block 550, the multiple limiting rods 520 are pushed to move horizontally at the same time to fix the flange. This is beneficial to ensure that the distance between the center of the flange and the center point of the multiple limiting rods 520 is the same after the flange is fixed, so that the center of the flange coincides with the center of the large gear in the drilling mechanism 400, and ensures that the distance between the multiple drill bits and the center of the flange is the same.

[0034] In some embodiments, such as Figure 2-3 As shown, in a preferred embodiment of the present invention, the fixing mechanism 500 further includes a third electric push rod 570 fixedly connected to the top of the mounting plate 510. A round block 571 is fixedly connected to the bottom end of the third electric push rod 570. An mounting rod 561 is fixedly connected to one side of the fixing plate 560. The other end of the mounting rod 561 passes through the limiting rod 520 and is fixedly connected to a telescopic rod 562. The other end of the telescopic rod 562 is fixedly connected to the surface of the round block 571.

[0035] In this embodiment of the utility model, the telescopic rod 562 includes a cylinder and a movable rod. The surface of the movable rod is slidably connected to the inner wall of the cylinder. One end of the cylinder is fixedly connected to the other end of the mounting rod 561. One end of the movable rod is fixedly connected to the surface of the circular block 571. When the limiting rod 520 moves, the mounting rod 561 will drive the cylinder to move.

[0036] After the limit rod 520 completes the position adjustment and fixation of the flange, the third electric push rod 570 is activated by control to push the round block 571 to move downward, so that the telescopic rod 562 drives the corresponding fixing plate 560 to move downward through the mounting rod 561, thereby tightening and fixing the top of the flange against the flange.

[0037] In this embodiment of the invention, the interaction between the multiple fixing plates 560 and the corresponding support plates 530 is beneficial to enhancing the fixing effect on the flange.

[0038] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, a limiting plate 533 is slidably connected to the inner wall of the support plate 530, and a threaded sleeve 531 is rotatably connected to the other end of the support plate 530. A lead screw 532 is threadedly connected to the inner wall of the threaded sleeve 531, and one end of the lead screw 532 passes through the support plate 530 and is fixedly connected to one side of the limiting plate 533.

[0039] In this embodiment of the utility model, the inner wall of the support plate 530 is provided with a moving groove that matches the limiting plate 533. When the fixing plate 560 is fixed to the flange, and the flange is further fixed, the operator rotates the threaded sleeve 531 to drive the screw 532 to move horizontally, thereby pushing the limiting plate 533 to move horizontally so that the limiting plate 533 and the outer edge of the flange are pressed against the flange.

[0040] In this embodiment of the utility model, the force exerted by the limiting plate 533 when it is fixed and the force exerted by the limiting rod 520 when it is fixed work together to enhance the stability of the flange during the drilling process.

[0041] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, a plurality of circular rods 551 arranged in a ring are fixedly connected to the surface of the flat-top cone block 550. The number and position of the circular rods 551 correspond one-to-one with the number and position of the limiting rods 520. The lower end of the inner wall of the limiting rod 520 is slidably connected to the surface of the corresponding circular rod 551.

[0042] In this embodiment of the utility model, when the driving limit rod 520 moves horizontally, the inner wall of the limit rod 520 will move along the surface of the round rod 551. When the flange is released from fixing, the driving flat-top cone block 550 moves downward. At this time, the flat-top cone block 550 will drive the corresponding limit rod 520 to reset and move through the round rod 551.

[0043] In this embodiment of the invention, it is advantageous to restore the device to its initial state after the flange is released from its fixation, thereby improving the device's practicality.

[0044] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, the bottom end of the fixing plate 560 and the other end of the limiting plate 533 are both fixedly connected with rubber pads, and the surface of the rubber pads is provided with a plurality of evenly distributed grooves.

[0045] In this embodiment of the utility model, when the fixing plate 560 and the limiting plate 533 are pressed against the flange, the surface of the rubber pad comes into contact with the flange, thereby strengthening the friction between the fixing plate 560, the limiting plate 533 and the flange during the fixing process, thereby enhancing the fixing effect.

[0046] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, a corrugated sleeve 534 is fixedly connected to one side of the inner wall of the support plate 530, and the other end of the corrugated sleeve 534 is fixedly connected to one side of the limiting plate 533.

[0047] In this embodiment of the utility model, the corrugated sleeve 534 is a rubber component. When the limiting plate 533 moves horizontally, it can drive the corrugated sleeve 534 to extend and retract. The lead screw 532 is placed on the inner wall of the corrugated sleeve 534, thereby achieving protection for the lead screw 532.

[0048] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, the inner wall of the mounting plate 510 is provided with a plurality of annularly distributed sliding grooves 511, and the top opening and bottom opening of the sliding grooves 511 are both funnel-shaped.

[0049] In this embodiment of the utility model, the number and position of the sliding grooves 511 correspond one-to-one with the number and position of the limiting rods 520. The surface of the limiting rod 520 is slidably connected to the inner wall of the corresponding sliding groove 511, thereby limiting the movement path of the limiting rod 520 and ensuring the stability of the limiting rod 520 when it moves horizontally.

[0050] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, a limiting block 512 is fixedly connected to the lower end of the surface of the limiting rod 520, and the surface of the limiting block 512 is slidably connected to the inner wall of the mounting plate 510.

[0051] In this embodiment of the utility model, the inner wall of the mounting plate 510 is provided with a moving groove that matches the limiting block 512. The moving groove is connected to the corresponding sliding groove 511 to prevent the limiting rod 520 from moving upward when it is squeezed by the flat-top cone block 550, thereby ensuring the stable operation of the device.

[0052] It should be noted that the electric linear actuators and motors mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the electric linear actuators and motors can be powered by built-in power supplies or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
