Description

Technical Field

[0001] The invention belongs to the technical field of pump body drilling, and in particular relates to a drilling device for submersible pump production. Background Art

[0002] A submersible pump is a specially designed pump. Since the pump body is located below the liquid, the possibility of air entering the pump inlet is reduced, which helps to maintain the efficiency and durability of the pump. At the same time, the submersible pump can effectively pump water from deeper places, such as deep wells or water sources. Submersible pumps can be used in a variety of applications, including industrial, agricultural, municipal water supply and domestic water systems. These pumps can be a form of centrifugal pumps or plunger pumps, and the specific type depends on the environment in which they are used and the performance required.

[0003] The pump body is an important part of the submersible pump. The difference from the ordinary pump body is that since the pump body is located below the liquid when working, once it is put into use, its subsequent maintenance and repair will become more difficult. Therefore, the pump body of the submersible pump needs to be accurately punched during production and processing to facilitate the subsequent accurate assembly of other parts on the pump body to reduce the frequency of subsequent maintenance. The drilling of the pump body generally requires the use of a special drilling device. There are many different types of drilling devices on the market, including various single-hole drilling devices and group drilling drilling devices. However, both single-hole drilling devices and group drilling drilling devices still have certain technical defects. First of all, the current pump The body punching device is usually a single-station clamping and processing structure. The clamping and disassembly process of the pump body cannot be used for alternating punching, which is very time-consuming and greatly affects the overall production and processing efficiency. At the same time, since the drilling and tapping of the pump body are often continuous processes, the existing processing equipment usually adopts a linear drive structure to move the punched pump body to the next tapping position. At this time, the punching device is idle, which will cause a waste of time. In addition, since the subsequent tapping position has not been calibrated, there will often be certain errors in the tapping process, which will also cause a certain proportion of defective products, thereby affecting the overall pass rate. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a drilling device for submersible pump production.

[0005] The technical solution adopted to solve the above technical problems is: a drilling device for submersible pump production, comprising a support base and a plurality of three-jaw chucks for clamping a pump body to be processed, a rotating support mechanism is fixedly installed at the front end of the top of the support base, a plurality of the three-jaw chucks are evenly installed on the top of the rotating support mechanism, and the rotating support mechanism is used to drive the plurality of three-jaw chucks to revolve; The rotating support mechanism is also provided with a synchronous rotating mechanism for driving the multiple three-jaw chucks to rotate; The rear end of the top of the support base is fixedly connected with a support frame, and the top of the support frame is rotatably connected with an automatic drilling and tapping mechanism for completing assembly-line drilling and tapping of the pump body to be processed.

[0006] Furthermore, the rotating support mechanism includes a support pedestal fixed to the top of the support base, the top of the support pedestal is fixedly connected to a first mounting frame, a first bearing is installed on the inner side of the first mounting frame, an inner gear ring is fixedly installed on the inner ring of the first bearing, a first servo motor is installed on the inner surface of the top of the support pedestal, the top of the output shaft of the first servo motor is fixedly connected to a first driving gear meshing with the inner gear ring, the top of the inner gear ring is fixedly connected to a fixing plate, and the top of the fixing plate is fixedly connected to a support platform.

[0007] Through the above technical scheme, the rotating support mechanism is mainly used to drive multiple three-jaw chucks to revolve, so as to realize assembly line operation during clamping, feeding, drilling and tapping, and at the same time ensure the displacement accuracy. During actual work, the output shaft of the first servo motor can drive the inner ring on the first bearing to rotate through the first driving gear, and then the fixed plate, support platform and multiple three-jaw chucks on the top can be driven to rotate synchronously through the inner ring, so as to realize the precise switching of the position of the pump body to be processed in different processing states, and then ensure that the pump body after drilling is completed can be accurately moved from the drilling position to the tapping position according to the fixed rotation angle, so as to ensure the subsequent tapping processing accuracy, and then ensure the product qualification rate.

[0008] Furthermore, the support base and the first mounting frame are an integrated structure, a circular hole is opened in the center of the top of the support base, the output shaft of the first servo motor passes through the circular hole and extends to the top thereof, and the first mounting frame is used for supporting and installing the first bearing.

[0009] Furthermore, the supporting platform is designed to have a triangular structure as a whole, and the multiple three-jaw chucks are respectively installed near the corners of the supporting platform.

[0010] Through the above technical scheme, the support platform with a triangular structure design has a revolution angle of 120 degrees each time. Each time it rotates, the pump bodies clamped on the three three-jaw chucks rotate 120 degrees synchronously. In this process, the pump body that has just been clamped will move to the punching position, the pump body that has been punched will move to the tapping position, and the pump body that has been tapped will return to the clamping position, thereby realizing the cycle, so that the drilling of the pump body can be realized in an assembly line continuous process, which not only saves time, but also improves the overall production and processing efficiency.

[0011] Furthermore, the synchronous rotation mechanism includes a second mounting frame fixed to the bottom of the supporting platform, a second bearing is fixedly mounted on the outer side of the second mounting frame, an outer gear ring is fixedly mounted on the outer ring of the second bearing, a plurality of the three-jaw chucks are fixedly connected to the bottom centers of the three-jaw chucks, a plurality of the bottom ends of the transmission shafts are fixedly mounted with driven gears meshing with the outer gear ring, a support plate is fixedly connected to the rear end of the outer wall of the supporting pedestal, a second servo motor is fixedly mounted on the support plate, and a second driving gear meshing with the outer gear ring is fixedly mounted on the top end of the output shaft of the second servo motor.

[0012] Through the above technical scheme, the synchronous rotation mechanism is mainly used to control the rotation of the pump body to be processed during the drilling and tapping process. Since each pump body to be processed needs to be processed with multiple evenly distributed holes on its circumference, after drilling a hole, the synchronous rotation mechanism needs to drive the pump body to be processed to rotate at a certain angle so as to complete the continuous automatic drilling of multiple holes. In specific work, after the drilling drill completes a drilling, the output shaft of the second servo motor will drive the second drive gear to rotate, and then the outer gear ring can be driven to rotate through the second drive gear. Since the position of the support platform remains fixed, the outer gear ring can simultaneously drive multiple driven gears to rotate during rotation, and then the corresponding three-jaw chuck and the pump body to be processed can be driven to rotate at a certain angle through the driven gear and the transmission shaft. In addition, since the movement of multiple groups of three-jaw chucks and the pump body to be processed is synchronized, the pump body to be processed at the drilling position and the tapping position can maintain synchronous movement, thereby ensuring the synchronization of drilling and tapping. At the same time, due to the accuracy of the movement position, the processing accuracy of the subsequent tapping processing is also guaranteed, thereby ensuring the processing quality of the body.

[0013] Furthermore, through holes are provided at the corners of the top of the support platform, and a plurality of transmission shafts pass through and are rotationally limited in the corresponding through holes.

[0014] Through the above technical solution, multiple transmission shafts can respectively realize the rotational support of multiple three-jaw chucks, so that multiple three-jaw chucks can subsequently rotate synchronously with the corresponding transmission shafts.

[0015] Furthermore, the automatic drilling and tapping mechanism includes two rotating arms, and telescopic hydraulic cylinders are installed at the front end centers of the two rotating arms. The front ends of the piston rods of the two telescopic hydraulic cylinders are fixedly connected to mounting seats, and lifting hydraulic cylinders are installed in the two mounting seats. Punching motors are installed at the bottom ends of the piston rods of the two lifting hydraulic cylinders, and the output ends of the two drilling motors are respectively installed with a drilling drill bit and a tapping drill bit.

[0016] Through the above technical scheme, when working, the positions of the two punching motors can be adjusted according to the punching and tapping positions of the pump body to be processed. If the radii of different batches of pump bodies to be processed are different, the angles can be adjusted by the two rotating arms, and then the extension length of the mounting seat can be adjusted by the two telescopic hydraulic cylinders, so that the punching and tapping positions of the punching drill bit and the tapping drill bit can be freely adjusted. When the position adjustment is fixed, processing can be carried out. During the processing, the two lifting hydraulic cylinders will drive the two punching motors to descend synchronously, and the two punching motors will also respectively drive the punching drill bit and the tapping drill bit to punch and tap the pump body directly below them.

[0017] Furthermore, a rotating support is provided at the top of the support frame, and the two rotating arms are rotatably connected to the rotating support in an up-and-down crossed state.

[0018] Through the above technical solution, the positions of the two rotating arms are symmetrical, thereby ensuring the synchronization of drilling and tapping and the processing accuracy.

[0019] Furthermore, the drilling drill bit and the tapping drill bit are respectively located above the two corresponding pump bodies to be processed. During the working process, the drilling drill bit and the tapping drill bit complete the drilling and tapping of the pump bodies to be processed in turn.

[0020] Furthermore, a controller is installed on the outer side wall of the support frame.

[0021] Through the above technical solution, the input end of the controller is electrically connected to the output ends of the rotating support mechanism, the synchronous rotation mechanism and the automatic punching and tapping mechanism, so that the rotating support mechanism, the synchronous rotation mechanism and the automatic punching and tapping mechanism can perform continuous automatic processing according to the control program of the controller.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention can drive the pump body to complete fully automatic precise revolution and rotation by designing a rotating support mechanism and a synchronous rotating mechanism, thereby realizing precise switching of the position of the pump body to be processed in different processing states. After the drilling is completed, the pump body can be accurately moved from the drilling position to the tapping position according to a fixed rotation angle, which not only ensures the subsequent tapping processing accuracy, but also ensures the qualified rate of the product; (2) The present invention can ensure that the pump body to be processed at the drilling position and the tapping position can maintain synchronous movement by designing a rotating support mechanism and a synchronous rotating mechanism, thereby ensuring the synchronization of drilling and tapping. At the same time, due to the accuracy of the movement position, the processing accuracy of the subsequent tapping processing is also guaranteed, thereby ensuring the processing quality of the main body; 3) The present invention designs a support platform with a triangular structure. Each time it rotates, the pump bodies clamped on the three three-jaw chucks rotate 120 degrees synchronously. During this process, the newly clamped pump body moves to the punching position, the punched pump body moves to the tapping position, and the tapped pump body returns to the clamping position, thereby realizing a cycle, so that the drilling of the pump body can be realized in an assembly line continuous process, which not only saves time but also improves the overall production and processing efficiency; (4) By designing an adjustable automatic drilling and tapping mechanism, for different radii and different batches of pump bodies to be processed, the positions of the two drilling motors can be adjusted according to the drilling and tapping positions of the pump bodies to be processed, so that the processing of pump bodies of different sizes can be completed, making it more applicable as a whole.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-Figure 12 As shown, a drilling device for submersible pump production in this embodiment includes a support base 1 and a plurality of three-jaw chucks 3 for clamping a pump body 8 to be processed. A rotating support mechanism 2 is fixedly installed at the front end of the top of the support base 1, and a plurality of three-jaw chucks 3 are evenly installed on the top of the rotating support mechanism 2. The rotating support mechanism 2 is used to drive the plurality of three-jaw chucks 3 to revolve.

[0027] like Figure 1-Figure 10As shown, the rotary support mechanism 2 includes a support pedestal 201 fixed to the top of the support base 1, a first mounting frame 202 is fixedly connected to the top of the support pedestal 201, a first bearing 203 is installed on the inner side of the first mounting frame 202, an inner gear ring 204 is fixedly installed on the inner ring of the first bearing 203, a first servo motor 205 is installed on the inner surface of the top of the support pedestal 201, a first driving gear 206 meshing with the inner gear ring 204 is fixedly connected to the top of the output shaft of the first servo motor 205, a fixed plate 207 is fixedly connected to the top of the inner gear ring 204, a support platform 208 is fixedly connected to the top of the fixed plate 207, and the rotary support mechanism 2 is mainly used to drive multiple three-jaw chucks 3 to revolve. , in order to realize assembly line operation in the process of clamping, feeding, punching and tapping, and at the same time ensure the displacement accuracy. During actual work, the output shaft of the first servo motor 205 can drive the inner ring 204 on the first bearing 203 to rotate through the first driving gear 206, and then the fixed plate 207, the supporting platform 208 and multiple three-jaw chucks 3 on the top can be driven by the inner ring 204 to rotate synchronously, so as to realize the precise switching of the position of the pump body 8 to be processed in different processing states, and then ensure that the pump body after the punching is completed can be accurately moved from the punching position to the tapping position according to the fixed rotation angle, so as to ensure the subsequent tapping processing accuracy, and then ensure the qualified rate of the product.

[0028] The support platform 208 is designed in a triangular structure as a whole, and multiple three-jaw chucks 3 are respectively installed near the corners of the support platform 208. The support platform 208 with a triangular structure has a revolution angle of 120 degrees each time. Each time it rotates, the pump bodies clamped on the three three-jaw chucks 3 rotate 120 degrees synchronously. During this process, the pump body that has just been clamped will move to the punching position, the pump body that has been punched will move to the tapping position, and the pump body that has been tapped will return to the clamping position, thereby realizing a cycle, so that the punching of the pump body can be realized in an assembly line-type continuous process, which not only saves time, but also improves the overall production and processing efficiency.

[0029] like Figure 6-Figure 10As shown, the rotating support mechanism 2 is also equipped with a synchronous rotating mechanism 4 for driving the multiple three-jaw chucks 3 to rotate; the synchronous rotating mechanism 4 includes a second mounting frame 401 fixed to the bottom of the supporting platform 208, a second bearing 402 is fixedly mounted on the outer side of the second mounting frame 401, an outer gear ring 403 is fixedly mounted on the outer ring of the second bearing 402, a transmission shaft 404 is fixedly connected to the bottom center of the multiple three-jaw chucks 3, and the bottom ends of the multiple transmission shafts 404 are fixedly mounted with gears meshing with the outer gear ring 403. The driven gear 405 of the support base 201 is fixedly connected to the rear end of the outer wall of the support base 201 with a support plate 406, on which a second servo motor 407 is fixedly installed, and a second driving gear 408 meshing with the outer gear ring 403 is fixedly installed at the top of the output shaft of the second servo motor 407. The synchronous rotation mechanism 4 is mainly used to control the rotation of the pump body 8 to be processed during the drilling and tapping process. Since each pump body 8 to be processed needs to be processed with multiple evenly distributed holes on its circumference, after drilling a hole, , it is necessary for the synchronous rotating mechanism 4 to drive the pump body 8 to be processed to rotate at a certain angle in order to complete the continuous automatic drilling of multiple holes. During the specific operation, when the drilling drill 606 completes a drilling, the output shaft of the second servo motor 407 will drive the second driving gear 408 to rotate, and then the outer ring gear 403 can be driven to rotate through the second driving gear 408. Since the position of the support platform 208 remains fixed, the outer ring gear 403 can simultaneously drive multiple driven gears 405 to rotate during rotation, and then the corresponding three-jaw chuck 3 and the pump body 8 to be processed can be driven to rotate at a certain angle through the driven gear 405 and the transmission shaft 404. In addition, since the movement of multiple groups of three-jaw chucks 3 and the pump body 8 to be processed is synchronized, the pump body 8 to be processed at the drilling position and the tapping position can maintain synchronous movement, thereby ensuring the synchronization of drilling and tapping. At the same time, due to the accuracy of the movement position, the processing accuracy of the subsequent tapping process is also guaranteed, thereby ensuring the processing quality of the main body.

[0030] Through holes are opened at the corners of the top of the support platform 208, and multiple transmission shafts 404 pass through and are rotationally limited in the corresponding through holes, so that the multiple transmission shafts 404 can respectively realize rotational support for multiple three-jaw chucks 3, so that the subsequent multiple three-jaw chucks 3 can rotate synchronously with the corresponding transmission shafts 404.

[0031] like Fig.12 As shown, a support frame 5 is fixedly connected to the top rear end of the support base 1, and an automatic drilling and tapping mechanism 6 is rotatably connected to the top of the support frame 5 for completing assembly-line drilling and tapping of the pump body 8 to be processed.

[0032] The automatic drilling and tapping mechanism 6 includes two rotating arms 601, and the front centers of the two rotating arms 601 are both installed with telescopic hydraulic cylinders 602. The front ends of the piston rods of the two telescopic hydraulic cylinders 602 are both fixedly connected with mounting seats 603. Lifting hydraulic cylinders 604 are both installed in the two mounting seats 603. The bottom ends of the piston rods of the two lifting hydraulic cylinders 604 are both installed with drilling motors 605. The output ends of the two drilling motors 605 are respectively installed with drilling bits 606 and tapping bits 607. When working, the positions of the two drilling motors 605 can be adjusted according to the drilling and tapping positions of the pump body 8 to be processed. Adjustment: If the radii of different batches of pump bodies 8 to be processed are different, their angles can be adjusted by two rotating arms 601, and then the extension length of the mounting seat 603 can be adjusted by two telescopic hydraulic cylinders 602, so that the drilling and tapping positions of the punching drill bit 606 and the tapping drill bit 607 can be freely adjusted. When the position is adjusted and fixed, processing can be carried out. During the processing, the two lifting hydraulic cylinders 604 will drive the two punching motors 605 to descend synchronously, and the two punching motors 605 will also respectively drive the punching drill bit 606 and the tapping drill bit 607 to drill and tap the pump body directly below them.

[0033] A rotating support is provided at the top of the support frame 5, and two rotating arms 601 are rotatably connected to the rotating support in an up-and-down crossed state. The positions of the two rotating arms 601 are symmetrical, thereby ensuring the synchronization of drilling and tapping and the processing accuracy.

[0034] The punching drill bit 606 and the tapping drill bit 607 are respectively located above the two corresponding pump bodies 8 to be processed. During the working process, the punching drill bit 606 and the tapping drill bit 607 complete the drilling and tapping of the pump bodies 8 to be processed in turn.

[0035] A controller 7 is also installed on the outer wall of the support frame 5. The input end of the controller 7 is electrically connected to the output ends of the rotating support mechanism 2, the synchronous rotation mechanism 4 and the automatic punching and tapping mechanism 6, respectively, so that the rotating support mechanism 2, the synchronous rotation mechanism 4 and the automatic punching and tapping mechanism 6 can perform continuous automatic processing according to the control program of the controller 7.

[0036] The working principle of this embodiment is as follows: during processing, the positions of the two punching motors 605 can be adjusted according to the punching and tapping positions of the pump body 8 to be processed. Specifically, the angles thereof can be adjusted by the two rotating arms 601, and then the extension length of the mounting seat 603 can be adjusted by the two telescopic hydraulic cylinders 602, so that the punching and tapping positions of the punching drill bit 606 and the tapping drill bit 607 can be freely adjusted; After the adjustment and fixation are completed, the operator clamps the pump body 8 to be processed on the corresponding three-jaw chuck 3, and then the output shaft of the first servo motor 205 can drive the inner gear ring 204 on the first bearing 203 to rotate through the first driving gear 206, and then the inner gear ring 204 can drive the fixing plate 207, the supporting platform 208 and the multiple three-jaw chucks 3 on the top to rotate synchronously, so as to realize the precise switching of the position of the pump body 8 to be processed in different processing states; Since the position of the support platform 208 remains fixed, the outer gear ring 403 can simultaneously drive multiple driven gears 405 to rotate when rotating, and then the corresponding three-jaw chuck 3 and the pump body 8 to be processed can be driven to rotate at a certain angle through the driven gear 405 and the transmission shaft 404. In addition, since the movement of multiple groups of three-jaw chucks 3 and the pump body 8 to be processed is synchronized, the pump body 8 to be processed at the drilling position and the tapping position can maintain synchronous movement, thereby ensuring the synchronization of the drilling drill bit 606 and the tapping drill bit 607 during the working process, thereby completing continuous clamping, drilling, tapping, blanking and clamping operations.
