Description

Technical Field

[0001] This utility model relates to the technical field of water meter drilling equipment, and more specifically, to a drilling device for adjusting the regulating hole of an adjustable water meter casing. Background Technology

[0002] An adjustable water meter is an intelligent metering device with flow regulation capabilities, typically composed of a mechanical metering mechanism and an electronic control module. Its core feature is a built-in adjustable valve, allowing for precise water flow management through user settings or remote signal control. It employs a rotary or screw-type metering structure to ensure measurement accuracy, and some models are equipped with a digital display screen to show real-time water consumption, flow rate, and valve status. Primarily used in scenarios requiring quantitative water supply, such as agricultural irrigation, industrial circulating water systems, or temporary water management, it effectively prevents water waste. It supports manual knob adjustment or remote control via the Internet of Things, combining the durability of mechanical components with the water-saving advantages of intelligent technology.

[0003] The regulating holes in the casing of adjustable water meters typically require the machining of multiple stepped holes of different diameters to meet the needs of flow regulation and sealing assembly. Traditional machining methods usually employ single-bit drilling equipment, completing the process by changing drill bits multiple times or machining different hole diameters at different workstations. This results in long machining cycles, low production efficiency, and difficulty in meeting the needs of mass production. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the prior art, this utility model provides a drilling device for the regulating hole of an adjustable water meter casing, which has the following advantages:

[0019] This adjustable water meter casing adjustment hole drilling device starts three drilling machines, each driving its own drill bit to rotate. A drive motor is activated, rotating a transmission threaded rod, which in turn moves a transmission block. The inclined block first moves the water meter casing to the drill bit with the largest diameter. At this point, the corresponding first hydraulic cylinder moves the corresponding drilling machine towards the water meter casing, completing the first step of drilling. The first hydraulic cylinder then moves the drilling machine in the opposite direction, causing the corresponding drill bit to detach from the water meter casing. The transmission threaded rod continues to rotate, driving the inclined block sequentially to the drill bits with the medium and smallest diameters, repeating the hydraulic cylinder operation. This allows for the completion of the stepped adjustment hole drilling of the water meter casing in a single operation, reducing the time spent repeatedly positioning the workpiece. The three drill bits operate in parallel, and the process switching is achieved by moving the workpiece instead of changing the tool, significantly improving the processing efficiency of the water meter casing adjustment hole.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example:

[0027] Please see Figures 1-3 A drilling device for adjusting the regulating hole of a water meter casing, comprising:

[0028] The base plate 1 has a mounting plate 2 fixedly connected to its top, and three first hydraulic cylinders 4 are fixedly installed on one outer surface of the mounting plate 2.

[0029] Three drilling machines 5 are fixedly connected to the output ends of three first hydraulic cylinders 4; and

[0030] Two support plates 6 are fixedly connected to the top of the base plate 1. A transmission threaded rod 12 is rotatably connected between the two support plates 6. A transmission block 13 is threadedly connected to the transmission threaded rod 12. An inclined block 8 is fixedly connected to the top of the transmission block 13. Two mounting rods 14 are fixedly connected to the inclined surface of the inclined block 8. A square plate 15 is fixedly connected to the upper end of the two mounting rods 14. A second hydraulic cylinder 16 is fixedly installed on the top of the square plate 15. A pressure block 17 is fixedly connected to the output end of the second hydraulic cylinder 16.

[0031] In a specific embodiment of this utility model, the drilling machine 5 is a common electric drilling device on the market, and its structural principle belongs to the prior art and will not be elaborated further. The drill bits installed on the three drilling machines 5 are different, and are distinguished by the diameter of the drill bit's circular cross-section, namely large, medium and small sizes. The drilling sequence is also in the order of the large, medium and small drill bits. The water meter shell is placed on the inclined surface of the inclined block 8. By controlling the second hydraulic cylinder 16 to start, the pressure block 17 is driven to press the water meter shell tightly on the inclined surface of the inclined block 8. Then, the three drilling machines 5 are started, and each drives its own drill bit to rotate. By controlling the rotation of the transmission threaded rod 12, the transmission block 13 is moved. The inclined block 8 first moves the water meter shell to the drill bit with the largest diameter. At this time, the corresponding first hydraulic cylinder 4 will drive the corresponding drilling machine 5 to move towards the water meter shell, completing the first step of drilling. The corresponding first hydraulic cylinder 4 then drives the drilling machine 5 to move in the opposite direction, so that the corresponding drill bit disengages. The water meter housing is separated, and then the drive threaded rod 12 continues to rotate, driving the inclined block 8 to the drill bit with a medium diameter via the drive block 13. The corresponding first hydraulic cylinder 4 drives the corresponding drilling machine 5 to move towards the water meter housing, completing the second drilling step. The corresponding first hydraulic cylinder 4 then drives the drilling machine 5 to move in the opposite direction, causing the corresponding drill bit to detach from the water meter housing. Then the drive threaded rod 12 continues to rotate, driving the inclined block 8 to the drill bit with the smallest diameter via the drive block 13. The corresponding first hydraulic cylinder 4 drives the corresponding drilling machine 5 to move towards the water meter housing, completing the final drilling step. The corresponding first hydraulic cylinder 4 then drives the drilling machine 5 to move in the opposite direction, causing the corresponding drill bit to detach from the water meter housing. Thus, the stepped adjustment hole drilling of the water meter housing is completed in a single operation, reducing the workpiece repositioning time. The three drill bits are on standby in parallel, and the process switching is achieved by moving the workpiece instead of changing the tool, significantly improving the processing efficiency of the adjustment hole of the water meter housing.

[0032] Specifically, a fixing plate 3 is fixedly connected to the top of the base plate 1, and three sets of support rods 11 are fixedly connected between the mounting plate 2 and the fixing plate 3. Each set of support rods 11 has two rods. A stabilizing block 10 is fixedly connected to the bottom of each drilling machine 5, and each stabilizing block 10 is slidably sleeved on the corresponding two support rods 11.

[0033] In this embodiment, each set of two support rods 11 is used to ensure that the drilling machine 5 remains stable when moving.

[0034] Specifically, a drive motor 9 is fixedly installed on one side of the outer surface of one of the support plates 6, and the output end of the drive motor 9 is fixedly connected to the transmission threaded rod 12.

[0035] In this embodiment, the drive motor 9 is started by controlling it to drive the corresponding transmission threaded rod 12 to rotate.

[0036] Specifically, a protective box 7 is fixedly connected between the two support plates 6, and the transmission threaded rod 12 is located inside the protective box 7.

[0037] In this embodiment, the protective box 7 is used to protect the transmission threaded rod 12 from being exposed.

[0038] Specifically, two limiting rods 19 are fixedly connected between the two support plates 6, and the inclined block 8 is slidably sleeved on the two limiting rods 19.

[0039] In this embodiment, the two limiting rods 19 ensure that the inclined block 8 maintains stable movement.

[0040] Specifically, the inclined surface of the inclined block 8 is fixedly connected to a positioning circular block 18.

[0041] In this embodiment, the water meter casing is fitted onto the positioning block 18, so that the position of the adjustment hole of the water meter casing corresponds to the drill bits of the three drilling machines 5.

[0042] Working principle: The water meter casing is placed on the inclined surface of the inclined block 8. The second hydraulic cylinder 16 is activated, driving the pressure block 17 to press the water meter casing firmly onto the inclined surface of the inclined block 8. Then, three drilling machines 5 are started, each driving its own drill bit to rotate. The drive motor 9 is activated, driving the transmission threaded rod 12 to rotate, which in turn moves the transmission block 13. The inclined block 8 first moves the water meter casing to the drill bit with the largest diameter. At this point, the corresponding first hydraulic cylinder 4 drives the corresponding drilling machine 5 to move towards the water meter casing, completing the first step of drilling. The corresponding first hydraulic cylinder 4 then drives the drilling machine 5 to move in the opposite direction, causing the corresponding drill bit to detach from the water meter casing. Then, the transmission threaded rod 12 continues to rotate, driving the inclined block 8 to the drill bit with the medium diameter via the transmission block 13. The corresponding first hydraulic cylinder 4 then drives the corresponding drilling machine 5 to move towards the water meter casing, completing the second step of drilling. The corresponding first hydraulic cylinder 4 then drives the drilling machine 5 to move in the opposite direction... The drill bit moves to the water meter housing, and the transmission threaded rod 12 continues to rotate, driving the inclined block 8 to the position of the smallest diameter drill bit via the transmission block 13. The corresponding first hydraulic cylinder 4 drives the corresponding drilling machine 5 to move towards the water meter housing, completing the final drilling step. The corresponding first hydraulic cylinder 4 then drives the drilling machine 5 to move in the opposite direction, causing the corresponding drill bit to detach from the water meter housing. Thus, the step-type adjustment hole drilling of the water meter housing is completed in a single process, reducing the workpiece repositioning time. The three drill bits are in parallel standby mode, and the process switching is achieved by moving the workpiece instead of changing the tool, which significantly improves the processing efficiency of the adjustment hole of the water meter housing. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in the field. Since this utility model is mainly used to protect the mechanical device, the control method and wiring layout will not be explained in detail.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
