Description

Technical Field

[0002] Related technology (Publication No. CN218225825U) discloses a grinding machine for water pump shaft production. The machine base includes a lifting and sliding base connected to it. A servo motor is fixed to the top of the lifting and sliding base, and a grinding wheel is connected to the connecting end of the servo motor. Telescopic clamping assemblies are fixed to both sides of the top surface of the machine base, and the water pump shaft is clamped between the two telescopic clamping assemblies.

[0003] In the process of implementing the above technical solution, it was found that there are at least the following problems in the related technology: This water pump shaft grinding machine, when in use, uses a telescopic clamping assembly to clamp the pump shaft and drive its rotation. The grinding wheel, driven by a servo motor, rotates, and the lifting base moves it horizontally and vertically. These three components work together to complete the grinding process. However, during the grinding process, the pump shaft is subjected to a unidirectional radial force from the grinder, making it susceptible to radial runout at high speeds, thus affecting the grinding effect.

[0017] The water pump shaft processing device provided by the technical solution disclosed in this disclosure can achieve the following technical effects: The present invention provides a water pump shaft machining device comprising a first circular plate, a first guide rail, a first slider, a first movable plate, a first rotating shaft, a grinding wheel, a support platform, a first driving member, a second driving member, and a third driving member. The first circular plate includes a through hole at its center for accommodating the water pump shaft to be ground. The first guide rails are mounted on the first circular plate along its radial direction and are evenly distributed around the center of the first circular plate. The number of first guide rails is an even number greater than or equal to four, and each is used to support and mount a slidable first slider. The first sliders are slidably mounted on a plurality of first guide rails, and the plurality of first sliders and the plurality of first guide rails each serve as a guide support. A first movable plate is mounted on each first slider and can move radially along the first circular plate under the guidance and support of the plurality of first sliders and the plurality of first guide rails. A first rotating shaft is rotatably mounted on each first movable plate along the axial direction of the first circular plate. The plurality of first rotating shafts are distributed in a regular polygonal pattern and are used to support and mount a grinding wheel. The grinding wheels are respectively installed on multiple first rotating shafts, and are all used to grind the water pump shaft passing through the through hole. The support platform is connected to the first circular plate, and is used to abut against the ground, thereby supporting the entire device. The first driving member is installed between the first circular plate and the multiple first movable plates, and is used to provide driving force to drive the multiple first movable plates to move closer to or separate from each other. The second driving member is installed between the first circular plate, the multiple first movable plates and the multiple first rotating shafts, and is used to provide driving force to drive the multiple first rotating shafts to rotate synchronously.

[0018] During use, after the water pump shaft to be polished is placed within the through-hole, the third drive member clamps both ends of the water pump shaft and drives the water pump shaft to move along and rotate about its axis. The second drive member then causes the multiple first rotating shafts to rotate synchronously, thereby driving the multiple grinding wheels to rotate synchronously. Finally, the first drive member, guided and supported by the multiple first guide rails and multiple first sliders, causes the multiple first movable plates to move toward each other, thereby driving the multiple first rotating shafts toward each other until the multiple grinding wheels abut against the water pump shaft, thereby polishing the water pump shaft. Because the number of first guide rails is an even number greater than or equal to four and the multiple first rotating shafts are arranged in a regular polygonal pattern, the number of grinding wheels is also an even number greater than or equal to four and is distributed in a regular polygonal pattern. Therefore, each grinding wheel is symmetrically distributed 180° relative to the other grinding wheels, balancing the radial forces acting on the water pump shaft from the multiple grinding wheels. This reduces radial runout during high-speed rotation of the water pump shaft, thereby improving the polishing effect. Moreover, since a plurality of grinding wheels grind the water pump shaft at the same time, the grinding efficiency is improved.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0030] Combine Figures 1 to 11As shown, an embodiment of the present disclosure provides a water pump shaft processing device, comprising a first circular plate 1, a first guide rail 2, a first slider 3, a first movable plate 4, a first rotating shaft 5, a grinding wheel 6, a support platform, a first driving member, a second driving member and a third driving member. The first circular plate 1 includes a through hole located at the center of its circle, and the through hole is used to accommodate the water pump shaft to be ground. The first guide rail 2 is installed on the first circular plate 1 along the radial direction of the first circular plate 1 and is evenly distributed around the center of the first circular plate 1. The number of the first guide rails 2 is an even number greater than or equal to four, and is respectively used to support and install the slidable first sliders 3. The first sliders 3 are respectively slidably installed on the multiple first guide rails 2, and the multiple first sliders 3 and the multiple first guide rails 2 are both used to act as guide supports. The first movable plate 4 is respectively installed on each first slider 3, and can be moved respectively along the radial direction of the first circular plate 1 under the guiding support of the multiple first sliders 3 and the multiple first guide rails 2. The first rotating shaft 5 is rotatably installed on each first movable plate 4 along the axial direction of the first circular plate 1. The multiple first rotating shafts 5 are distributed in a regular polygon and are respectively used to support and install grinding wheels 6. The grinding wheels 6 are respectively installed on the multiple first rotating shafts 5, and are all used to grind the water pump shaft passing through the through hole. The support platform is connected to the first circular plate 1 and is used to abut against the ground, thereby supporting the entire device. The first driving member is installed between the first circular plate 1 and the multiple first movable plates 4, and is used to provide driving force to drive the multiple first movable plates 4 to move closer to or separate from each other. The second driving member is installed between the first circular plate 1, the multiple first movable plates 4 and the multiple first rotating shafts 5, and is used to provide driving force to drive the multiple first rotating shafts 5 to rotate synchronously. The third driving member is installed on the support platform, and is used to provide driving force to clamp the two ends of the water pump shaft and drive the water pump shaft to move along its axis and rotate around its axis.

[0031] The present disclosure provides a water pump shaft processing device. After the water pump shaft to be polished is placed inside a through hole, a third driving member is used to clamp the ends of the water pump shaft and drive the water pump shaft to move along and rotate around its axis. Then, a second driving member is used to synchronize the rotation of multiple first rotating shafts 5, thereby driving multiple grinding wheels 6 to rotate synchronously. Finally, the first driving member, and the guiding support of multiple first guide rails 2 and multiple first sliders 3, can bring multiple first movable plates 4 closer together, thereby driving multiple first rotating shafts 5 closer together until the multiple grinding wheels 6 abut against the water pump shaft, thereby polishing the water pump shaft. Since the number of first guide rails 2 is an even number greater than or equal to four and the multiple first rotating shafts 5 are distributed in the form of a regular polygon, the number of grinding wheels 6 is an even number greater than or equal to four and is distributed in the form of a regular polygon. Therefore, each grinding wheel 6 is 180° symmetrically distributed with respect to the other grinding wheels 6, so that the radial forces exerted on the water pump shaft by the multiple grinding wheels 6 are balanced. Thereby reducing the radial runout when the water pump shaft rotates at a high speed, thereby improving the grinding effect. In addition, since a plurality of grinding wheels 6 grind the water pump shaft at the same time, the grinding efficiency is improved.

[0032] Optionally, combined Figure 1 、 Figure 5 and Figure 7 As shown, the first bearing block is also included. The first bearing blocks are respectively mounted on the plurality of first rotating shafts 5 and are respectively installed on the plurality of first movable plates 4.

[0033] In the disclosed embodiment, the plurality of first seated bearings are used to reduce the friction between the plurality of first rotating shafts 5 and the plurality of first movable plates 4 and to improve the precision of the plurality of first rotating shafts 5 when rotating relative to the plurality of first movable plates 4 .

[0034] Optionally, Figure 1 、 Figure 7 and Figure 8 The support platform includes a support plate 7, a base 8, and a first support arm 9.

The base 8 is respectively installed at the four corners of the bottom surface of the support plate 7 and is used to abut against the ground. The first support arm 9 is installed on the top surface of the support plate 7 for supporting and installing the first circular plate 1. Among them, the first circular plate 1 is installed on the top of the support arm.

[0035] In the embodiment of the present disclosure, the support plate 7, the base 8 and the first support arm 9 together constitute a support platform, which is located on the ground and supports relevant components of the installation device.

[0036] Optionally, combined Figure 1 、 Figure 2 、 Figure 7 and Figure 10As shown, the third driving member includes a second circular plate 10, a second guide rail 11, a second slider 12, a second movable plate 13, a cam bearing 14, a first cylinder 15, a second cylinder 16, a first connecting rod 17, a first rotating arm 18, a first support shaft 19, and a first hydraulic cylinder 20. The second circular plate 10 is coaxially arranged with the first circular plate 1 and is located on both sides of the first circular plate 1 along the axial direction of the first circular plate 1. The second circular plates 10 on both sides are respectively used to support the relevant components of the installation device. The second guide rails 11 are respectively installed on the opposite surfaces of the second circular plates 10 on both sides along the radial direction of the second circular plate 10 and are evenly distributed around the center of the second circular plates 10 on both sides. The number of second guide rails 11 on each side is greater than or equal to three, and each is used to support and install the slidable second sliders 12. The second sliders 12 are slidably installed on the multiple second guide rails 11 on both sides. The multiple second guide rails 11 and the multiple second sliders 12 on both sides are used to serve as guide supports. The second movable plates 13 are respectively mounted on the multiple second sliders 12 on both sides, and can move in the radial direction of the second circular plates 10 on both sides under the guiding and supporting action of the multiple second guide rails 11 and multiple second sliders 12 on both sides. Cam bearings 14 are respectively mounted on the multiple second movable plates 13 on both sides, and the multiple cam bearings 14 on the same side are distributed in a regular polygonal shape, and are all used to abut against the water pump shaft. The first cylinder 15 is respectively connected to the annular side surfaces of the second circular plates 10 on both sides, and is respectively coaxially distributed with the second circular plates 10 on both sides, and is respectively used to support and install the rotatable second cylinder 16. The second cylinder 16 is respectively rotatably mounted on the second cylinders on both sides, and can respectively perform rotational motion relative to the second cylinders 16 on both sides. The first connecting rod 17 is respectively rotatably mounted between the second cylinder 16 and each second movable plate 13, and is both used to transmit driving force. The first rotating arm 18 is respectively connected to the inner side surfaces of the second cylinders on both sides, and is respectively used to drive the second cylinders on both sides to rotate. First support shafts 19 are mounted on opposite sides of the second circular plate 10 along the axial direction of the first circular plate 1. They support and mount rotatable first hydraulic cylinders 20. The first hydraulic cylinders 20 are rotatably mounted between the first support shafts 19 and the first rotating arms 18, providing driving force. Driven by the first hydraulic cylinders 20, both ends of the water pump shaft are clamped.

[0037] In the disclosed embodiment, by controlling the operation of the first hydraulic cylinders 20 on both sides, the first rocker arms on both sides can drive the second rockers on both sides to reciprocate. Under the pull or push of the multiple first connecting rods 17 on both sides, and the guiding and supporting action of the multiple first guide rails 2 and multiple first sliders 3 on both sides, the multiple second movable plates 13 on both sides can separate from or move closer to each other, thereby driving the multiple cam bearings 14 on both sides to loosen or clamp the two ends of the water pump shaft. In addition, by clamping the two ends of the water pump shaft with the multiple cam bearings 14 on both sides, the water pump shaft can rotate around its axis while axially fixing the water pump shaft.

[0038] Optionally, combined Figure 1 and Figure 2 As shown, the first bearing is also included. The first bearing is installed between the first cylinder 15 and the second cylinder 16.

[0039] In the embodiment of the present disclosure, the first bearing is used to reduce the friction between the first cylinder 15 and the second cylinder 16 and to improve the rotation accuracy of the second cylinder 16 when rotating relative to the first cylinder 15 .

[0040] Optionally, combined Figure 1 、 Figure 7 and Figure 8 As shown, the third drive member also includes a third guide rail 21, a third slider 22, a moving frame 23, a second support arm 24, a nut 25, a lead screw 26, and a first motor 27. The third guide rail 21 is mounted on the bottom surface of the support plate 7 along the axial direction of the first circular plate 1 and is used to support and mount the slidable third slider 22. The third slider 22 is slidably mounted on the third guide rail 21 and is located on both sides of the third guide rail 21 along the axial direction of the first circular plate 1. The third guide rail 21 and the third sliders 22 on both sides serve as guides and supports. The moving frame 23 is mounted on each side of the third slider 22 and is sleeved on the support plate 7. Under the guidance and support of the third guide rail 21 and the third sliders 22 on both sides, it can move along the axial direction of the first circular plate 1. The second support arms 24 are mounted on the top surfaces of the moving frames 23 on both sides. The second circular plate 10 on both sides is mounted on the top of the second support arms 24 on both sides, respectively, to determine the positional relationship between the second circular plate 10 and the moving frames 23 on both sides. The nuts 25 are mounted on the movable frames 23 on both sides along the axial direction of the first circular plate 1, and are used to drive the movable frames 23 on both sides to move. The lead screws 26 are mounted on the nuts 25 on both sides and are respectively passed through the movable frame 23 on the other side. The axes of the lead screws 26 on both sides are parallel to each other and are used to convert rotational motion into linear motion. The first motor 27 is mounted on the bottom surface of the support plate 7 and is opposite to the lead screws 26 on both sides. Both are used to provide driving force to achieve the rotational motion function. The rotating ends of the first motors 27 on both sides are connected to the lead screws 26 on both sides through first couplings. Among them, under the drive of the first motors 27 on both sides, the water pump shaft moves along its axis.

[0041] In the disclosed embodiment, the motors on both sides are controlled separately, and the lead screws 26 on both sides are driven to rotate via the first couplings on both sides. Under the guidance and support of the third guide rail 21 and the third sliders 22 on both sides, the nuts 25 on both sides respectively drive the movable frame 23 to move. This in turn drives the second support arms 24 on both sides to move, and then adjusts the position of the second circular plates 10 on both sides. Similarly, by synchronously controlling the motors on both sides, the second movable plates 13 on both sides can be moved synchronously. Therefore, before clamping the water pump shaft, the multiple cam bearings 14 on both sides can be distributed around the ends of the water pump shaft. After clamping the water pump shaft, the multiple cam bearings 14 on both sides can drive the water pump shaft to reciprocate along its axis. Furthermore, the design of the third guide rail 21, third slider 22, movable frame 23, second support arm 24, nut 25, lead screw 26, and first motor 27 being located below the support plate 7 prevents dust generated during grinding from directly falling onto its surface.

[0043] In the disclosed embodiment, a plurality of second seated bearings are used to improve the rotation accuracy of the lead screws 26 on both sides and reduce the vibration of the lead screws 26 on both sides during rotation.

[0044] Optionally, combined Figure 1 、 Figure 3 、 Figure 4 and Figure 7As shown, the third driving member also includes a first spline sleeve 28, a first spline shaft 29, a top plate 30, a third movable plate 31, a second hydraulic cylinder 32 and an extension rod 33.

Second hydraulic cylinders 32 are mounted on either side of the second support arms 24, along the axial direction of the first circular plate 1, providing driving force to achieve linear movement. Extension rods 33 are mounted between the movable ends of the second hydraulic cylinders 32 and the third movable plates 31, respectively, to adjust the distance between the third movable plates 31 and the movable ends of the second hydraulic cylinders 32. Driven by the second hydraulic cylinders 32, the ends of the water pump shaft are pressed against each other.

[0045] In the disclosed embodiment, the operation of the second hydraulic cylinders 32 on both sides drives the movement of the two movable plates via the extension rods 33 on both sides, thereby driving the first spline shafts 29 on both sides to slide relative to the first spline sleeves 28 on both sides, ultimately forcing the top plates 30 on both sides to respectively abut the ends of the water pump shaft. While the water pump shaft is axially fixed, the top plates 30 on both sides can drive the water pump shaft to rotate about its axis due to the action of friction.

This in turn drives the second spline sleeves 34 on both sides, which in turn drives the first gears on both sides. This in turn drives the first spline sleeves 28 on both sides via the first toothed belts 35 on both sides. This in turn drives the first spline shafts 29 on both sides, and ultimately drives the top plates 30 on both sides, achieving the function of rotating the water pump shaft around its axis.

[0055] In the embodiment disclosed herein, after the multiple third spline sleeves 41 rotate synchronously under the drive of external force, they can drive the multiple third spline shafts 40 to rotate, and then drive the multiple first bevel gears to rotate. Through the meshing action between the teeth, the multiple second bevel gears can be driven to rotate. Then, the multiple second rotating shafts 38 can be driven to rotate, and then the multiple third belt gears can be driven to rotate. Through the multiple second toothed belts 39, the multiple fourth belt gears can be driven to rotate. Then, the multiple first rotating shafts 5 can be driven to rotate, and finally the function of synchronous rotation of the multiple grinding wheels 6 is achieved. In addition, since the multiple third spline shafts 40 and the multiple third spline sleeves 41 can slide with each other, the multiple grinding wheels 6 can be made to move closer to or separate from each other while the multiple grinding wheels 6 rotate.

[0056] Optionally, a third bearing block is further included, which is respectively mounted on the plurality of second rotating shafts 38 and respectively installed on the plurality of first movable plates 4 .

The third cylinder 42 is connected to the annular side surface of the first circular plate 1 and is coaxial with the first circular plate 1. It supports and mounts the rotatable fourth cylinder 43. The fourth cylinder 43 is rotatably mounted on the third cylinder 42, allowing rotational movement relative to the third cylinder 42. The fourth cylinder 43 includes bevel teeth and spur teeth at both ends, both of which are used to transmit driving force. The bevel teeth mesh with the third bevel gear.

[0063] In the disclosed embodiment, controlling the third motor 45 drives the spur gear 46 to rotate. This, through inter-tooth meshing, drives the fourth cylinder 43 to rotate. This, again through inter-tooth meshing, drives the third bevel gear to rotate. This, in turn, drives the multiple third splined sleeves 41 to rotate synchronously, ultimately achieving the function of synchronized rotation of multiple grinding wheels 6.

Subsequently, the multiple first movable plates 4 are pulled or pushed by the second connecting rod 49, moving them toward or away from each other, ultimately driving the multiple grinding wheels 6 toward or away from each other to grind the water pump shaft. Compared to a method of driving the multiple first movable plates 4 individually, this reduces the number of power sources.

The electric push rod 52 is rotatably installed between the second support shaft 51 and the second rotating arm 50, and can perform rotational motion relative to the second support shaft 51 and the second rotating arm 50 respectively.

[0071] In the disclosed embodiment, by controlling the operation of the electric push rod 52, the second rotating arm 50 drives the fifth cylinder 47 to reciprocate, thereby driving the disc to reciprocate. Subsequently, the multiple first movable plates 4 are pulled or pushed by the second connecting rod 49 to move toward or away from each other, ultimately driving the multiple grinding wheels 6 toward or away from each other. Furthermore, using the electric push rod 52 as the power source makes it easier to precisely control the feed rate during grinding.
