Description

Technical Field

[0001] This utility model relates to the field of pumping equipment, and specifically to a pump body positioning device. Background Technology

[0002] "Pump" is a common term for "pump" in some regions, while "pump water machine" specifically refers to pump-type equipment used for transporting water, and its function and principle are completely consistent with that of a "water pump." The pump water machine body is the core component, containing multiple channels for fluid transport (such as inlet channels, outlet channels, impeller chambers, etc.). During the manufacturing process, the inner walls of these channels require precision machining such as grinding and milling to ensure smoothness, dimensional accuracy, and connectivity, thereby ensuring the pump's flow rate, pressure, and energy consumption performance during operation.

[0003] However, pump bodies are often irregularly shaped, and the processing requires handling channels in different orientations. If the pump body is not stably secured, it is prone to displacement or shaking during grinding or milling due to external forces (such as cutting force from the tool). This can lead to channel size deviations, excessive inner wall roughness, and even machining position misalignment, severely affecting the assembly accuracy and performance of the pump body. Therefore, a device capable of precisely positioning and firmly clamping the pump body is needed to ensure the stability and accuracy of the processing. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solution: A pump body positioning device includes: a machine base, a positioning seat, a side rotating fixed pressure rod, and a middle rotating fixed pressure rod. The positioning seat is fixedly fixed to the machine base at intervals. The positioning seat has a through hole in the middle and a frustum at the upper end. The outer ring of the positioning seat has an insertion hole, and the upper end of the insertion hole has a retaining ring. The side rotating fixed pressure rod is set on the upper end of the machine base and located on both sides of the positioning seat. The middle rotating fixed pressure rod is set on the machine base and located between the positioning seats. The side rotating fixed pressure rod includes a fixed seat one and a single-headed rotating rod. The middle rotating fixed pressure rod includes a fixed seat two and a double-headed rotating rod. The fixed seat one and the fixed seat two are fixed to the machine base. The single-headed rotating rod is threadedly rotatably set on the upper end of the fixed seat one, and the double-headed rotating rod is threadedly rotatably set on the upper end of the fixed seat two.

[0006] In a further improvement, the machine tool is equipped with a rotating component, which includes a base and a rotational power component.

[0016] The following describes the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0017] Example 1

[0018] A pump body positioning device includes: a machine base 1, a positioning seat 2, a side rotating fixing pressure rod 3, and a middle rotating fixing pressure rod 4. The positioning seat 2 is fixedly fixed to the machine base 1 at intervals. The positioning seat 2 has a through hole 21 in the middle and a frustum 22 at the upper end. The outer ring of the positioning seat 2 has an insertion hole 23 and a retaining ring 24 at the upper end of the insertion hole 23. The side rotating fixing pressure rod 3 is located on the upper end of the machine base 1 and on both sides of the positioning seat 2. The middle rotating fixing pressure rod 4 is located on the machine base 1 and between the positioning seats 2. The side rotating fixing pressure rod 3 includes a first fixing seat 31 and a single-headed rotating rod 32. The middle rotating fixing pressure rod 4 includes a second fixing seat 41 and a double-headed rotating rod 42. The first fixing seat 31 and the second fixing seat 32 are fixed to the machine base 1. The single-headed rotating rod 32 is threadedly rotatably disposed on the upper end of the first fixing seat 31, and the double-headed rotating rod 42 is threadedly rotatably disposed on the upper end of the second fixing seat 41.

[0019] The truncated cone, insertion hole, and retaining ring of the positioning seat are precisely matched with the bottom structure of the pump body, restricting the displacement of the pump body in three dimensions: horizontal translation, circumferential rotation, and vertical movement, ensuring the accuracy of the machining position; the single-headed rotating rod and the double-headed rotating rod generate continuous pressure through threaded transmission, tightly pressing the pump body from the top, and together with the bottom limit, can effectively resist the cutting force during machining and prevent the pump body from shaking.

[0020] As a further preferred embodiment, the machine tool 1 is equipped with a rotating assembly 5, which includes a base 51 and a rotating power assembly 52. ​​The machine tool 1 is rotatably mounted inside the base 51, and one end is connected to the rotating power assembly 52, which drives the machine tool 1 to rotate. The base provides support for the machine tool, which is rotatably connected to the inside of the base via bearings or other structures. The rotating power assembly (such as a servo motor or gearbox) is connected to one end of the machine tool and can output torque to drive the machine tool to rotate around its own axis. Since the pump body is fixed on the machine tool, the machine tool can drive the pump body to rotate synchronously when it rotates, thereby changing the processing angle of the pump body. The orientation of the pump body can be adjusted without disassembling it, which facilitates grinding and milling of channels in different positions of the pump body (such as side or inclined holes), reduces positioning errors caused by repeated clamping, and improves processing convenience and efficiency. The rotating power assembly can precisely control the rotation angle to meet the requirements of high-precision processing.

[0021] As a further preferred embodiment, the positioning seats 2 are arranged in three sets at intervals, and the side rotating fixed pressure rods 3 and the middle rotating fixed pressure rods 4 are each provided in two sets. The three sets of positioning seats are evenly distributed along the length of the machine table, forming three independent positioning stations; the two sets of side rotating fixed pressure rods are located on both sides of the machine table, each set corresponding to the two outermost positioning seats (the left pressure rod corresponds to the first pump body from the left, and the right pressure rod corresponds to the first pump body from the right); the two sets of middle rotating fixed pressure rods are located between the three positioning seats (the first set of middle pressure rods corresponds to the first and second pump bodies from the left, and the second set of middle pressure rods corresponds to the second and third pump bodies from the left). This layout ensures that each pump body is subjected to the clamping force of at least one pressure rod (the outer pump body is subjected to the side pressure rod and the adjacent middle pressure rod, and the middle pump body is subjected to the force of two sets of middle pressure rods), forming a symmetrical and stable clamping structure.

[0022] As a further preferred embodiment, the insertion holes 23 and retaining rings 24 are provided in five sets at annular intervals. The bottom of the water pump body is usually provided with multiple protrusions and positioning posts for assembly or positioning (the number and position vary depending on the model). The five sets of insertion holes at annular intervals on the positioning seat can accommodate different numbers and different circumferential positions of positioning posts (e.g., pump bodies with 3-5 positioning posts can be inserted into the corresponding insertion holes). The circumferential rotation of the pump body is restricted by the cooperation between the holes and the posts. The retaining ring at the upper end of each set of insertion holes can abut against the corresponding position on the bottom of the pump body, and jointly bear the vertical force of the pump body from multiple points, avoiding deformation caused by excessive force on a single retaining ring.

[0023] like Figures 1-3 As shown, the pump body positioning device in this embodiment achieves the fixation of the pump body through a combination structure of "bottom limiting + upper clamping". The specific principle is as follows:

[0024] The positioning seat limits the bottom of the pump body: The positioning seat is fixed on the machine base, and its upper frustum is adapted to the groove or stepped structure at the bottom of the pump body, which can limit the horizontal translation of the pump body; the through hole in the middle can accommodate the protruding structure at the bottom of the pump body (such as bushing, connecting column, etc.), avoiding interference with the positioning of the bottom structure; the annular insertion hole on the outer side is adapted to the positioning post at the bottom of the pump body, further limiting the circumferential rotation of the pump body; the retaining ring at the upper end of the insertion hole can abut against the edge of the bottom of the pump body to prevent the pump body from moving upward during processing, achieving precise positioning of the bottom in all directions.

[0025] The upper ends of the side-rotating fixed pressure rod and the middle-rotating fixed pressure rod are clamped together: The side-rotating fixed pressure rod consists of a fixed seat and a single-headed rotating rod. The fixed seat provides support together. The single-headed rotating rod moves up and down vertically when rotating through a threaded engagement with the fixed seat. When the single-headed rotating rod moves downward, its end presses against the upper side of the pump body. The middle-rotating fixed pressure rod consists of a fixed seat and a double-headed rotating rod. The two ends of the double-headed rotating rod correspond to the pump bodies on two adjacent positioning seats. When it moves downward through the threaded rotation, both ends press against the upper middle of the two pump bodies simultaneously.

[0026] Multiple sets of synchronous fixing: Three sets of positioning seats are set at intervals, corresponding to three water pump bodies; the side rotation fixing pressure rods are located on both sides of the positioning seats (each set of side pressure rods corresponds to the side of the pump body), and the middle rotation fixing pressure rods are located between the positioning seats (each set of middle pressure rods corresponds to two adjacent pump bodies). Through the cooperation of the bottom limit and the upper clamping, the three sets of pump bodies can be stably fixed at the same time.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
