[0002] Since the pump casings of industrial pumps are mostly large box-type parts, when the pump shaft and impeller use flat keys or semi-circular keys to transmit torque, the inside of the pump casing needs to be machined with an internal keyway that matches the key. The internal keyway is usually a vertical strip groove. During the grooving process of the pump casing, gantry milling equipment will be used for vertical milling.

[0004] During the milling process, a large amount of waste will be separated from the pump casing, but the existing equipment is unable to transfer the waste in time, so the waste accumulates inside the pump casing. When one workpiece is completed, it needs to be cleaned before the next workpiece can be fixedly milled, resulting in low processing efficiency. Summary of the Invention

Four clamping parts that can rotate at different angles can be rotated to different degrees according to the diameter of the pump casing to complete the clamping of the pump casing. Through gravity clamping, when the pump casing is placed, it can be quickly clamped and positioned. When the material transporting robot arm applies upward force to the pump casing, the clamping parts will reduce the clamping force on the pump casing, thereby facilitating the loading and unloading of the pump casing. The pressure ring fixed under the bottom cover will squeeze the bottom plate during the downward movement. The multiple bottom plates will provide vertical support for the pump casing from below. The bottom plate will deflect downward, thereby driving the clamping parts above to squeeze and contact the pump casing, thereby completing the horizontal clamping of the pump casing. The pump casing is clamped and fixed in both vertical and horizontal directions, ensuring that the impact force of vibration is dispersed during the processing; When the milling actuator starts processing, it will generate a large downward impact force, which will press the contact strip into the liquid chamber, causing the extrusion strip to squeeze the buffer inside the liquid chamber, dispersing the impact force and achieving a buffering effect. Through multi-directional limit fixation and the buffer shock absorption at the bottom, the vibration frequency during the milling process can be effectively reduced, the swing amplitude of the pump housing can be reduced, and the flatness of the milling position can be ensured; When the milling actuator starts working, it will drive the squeezing bar to squeeze the liquid inside the liquid chamber. After the liquid is impacted and squeezed, it will enter the connecting chamber, thereby squeezing the push piece installed at the upper end of the connecting chamber, causing the push piece to squeeze and push outward. The push piece will drive the slide bar to move outward, causing the positioning piece to contact the positioning seat. The positioning teeth on the positioning piece and the positioning seat will contact and lock each other, thereby locking the connecting shaft to prevent the connecting shaft from deflecting and ensure the clamping effect on the pump housing. The material and quantity of the tension spring can be replaced according to the different volumes and specifications of the pump body. A large pump body is heavy and requires a tension spring with greater tension. A small pump body can use a tension spring with less tension. It can be adjusted according to different pump bodies to ensure the lifting of pump bodies of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as within the scope of the present invention without substantially changing the technical content.

[0021] Reference Figures 1-9 A gantry milling device for industrial pump production comprises: a machine tool 1, a transmission assembly 2 mounted on the machine tool 1, and a milling assembly 3 mounted on the machine tool 1; a processing table 4 is provided on the transmission assembly 2; a placement opening is provided in the middle of the processing table 4; a bottom cover 5 is provided in the middle of the placement opening; the bottom cover 5 is an upwardly protruding circular cover and has a plurality of slag strip discharge openings equidistantly provided thereon; four mounting openings are provided in an annular shape on the upper surface of the processing table 4, and the centers of the four mounting openings coincide with the center of the bottom cover 5; Four clamping assemblies 6 are respectively provided inside the four mounting ports, and the four clamping assemblies 6 are used to clamp the industrial pump. The clamping assembly 6 includes a base plate 61, a connecting shaft 62, an upper plate 63 and a clamping member 64. The connecting shaft 62 is rotatably installed inside the mounting port, the base plate 61 is fixedly connected to the lower end of the connecting shaft 62, the upper plate 63 is fixedly connected to the upper end of the connecting shaft 62, and the clamping member 64 is fixedly connected to the upper end of the upper plate 63. The bottom cover 5 moves downward to drive the four clamping assemblies 6 to deflect, and the four clamping members 64 clamp the industrial pump.

[0022] In the embodiment of the above technical solution, since the pump casing to be processed is usually transferred by a robot and is relatively large in size, if the position of the pump casing is offset after placement, manual fine-tuning is impossible. In this application, the pump casing that needs to be milled is placed on the bottom cover 5. Since the bottom cover 5 is set as an upwardly protruding circular cover, it is convenient for the center of the pump casing to be quickly aligned with the center of the bottom cover 5 during the placement process. At the same time, after the pump casing is placed on the bottom cover 5, the weight of the pump casing will drive the bottom cover 5 to move downward. The bottom cover 5 squeezes and pushes the four bottom plates 61 below, thereby deflecting the bottom plates 61 to the side away from the center. The clamping member 64 fixedly connected to the other end of the connecting shaft 62 will approach the pump casing, thereby quickly clamping and positioning the pump casing through the four clamping components 6, and loading and unloading are fast.

[0023] When processing begins, a large amount of waste will be generated along with milling. This part of the waste will be located inside the pump casing. The two sides of the slag strip outlet are inclined to form an inverted eight-shaped feed port. When waste is generated, it will slide along the upper surface of the bottom cover 5, which facilitates the rapid discharge of waste from the slag strip outlet position, thereby avoiding waste accumulation on the surface of the bottom cover 5.

[0024] The present invention can quickly guide out and clean the waste generated during the milling process, thereby avoiding the waste from accumulating inside the pump casing. There is no need to clean the processing table after the milling is completed, thereby improving the processing efficiency.

[0025] The preferred technical solution in this embodiment is: Reference Figure 3 The milling assembly 3 includes a fixed frame 31, a driving seat 32 and a milling actuator 33. The fixed frame 31 is arranged on the machine tool 1, the driving seat 32 is slidably arranged on the side of the fixed frame 31, and the milling actuator 33 is fixedly installed on the control end of the driving seat 32.

[0026] The fixed frame 31 is a gantry, which is a closed structure composed of a crossbeam, left and right columns and a base. The crossbeam can move vertically along the columns, the workbench moves horizontally along the base, and the milling actuator 33 moves laterally along the crossbeam. Through the linear motion of the X / Y / Z axes, in conjunction with the transmission component 2 or the swing-angle milling head, 5-axis linkage processing of complex surfaces is achieved. By setting up the milling actuator 33 using hard-coated tools or super-hard tools, rapid milling processing of industrial pumps of different sizes can be achieved.

[0027] Reference Figure 6 and Figure 7 The clamping member 64 is an arc-shaped block, and a plurality of contact pieces are provided on one side close to the center of the processing table 4. The contact pieces are made of elastic material and are used to fix the industrial pump.

[0028] When clamping and fixing pump casings of different diameters, the existing clamping method is mostly rigid clamping through multiple cylinders. If the clamping force of the pump casing is not controlled well, the outer surface of the pump casing will be squeezed and deformed, thereby affecting the normal use of the pump casing.

[0029] Through four clamping members 64 that can rotate at different tilt angles, they automatically rotate to different degrees according to the diameter of the pump casing, thereby completing the clamping of the pump casing. In addition, the multiple contact pieces of elastic material arranged on the surface can increase the friction during the clamping process, thereby strengthening the grip with the pump casing surface and ensuring the clamping effect of the pump casing during the processing.

[0030] The present application is clamped by gravity, and when the pump casing is placed, rapid clamping and positioning are completed. When the material transporting robotic arm applies an upward force to the pump casing, the clamping member 64 will reduce the clamping force on the pump casing, thereby facilitating the loading and unloading of the pump casing.

[0031] Reference Figure 4 and Figure 5 The processing table 4 includes a table body 41 and a collecting plate 42. A collecting groove is provided on the side of the table body 41. The collecting plate 42 is slidably provided inside the collecting groove. A circular protrusion is provided in the middle of the collecting plate 42.

[0032] The pump casing that needs to be milled is placed above the platform 41. During the processing, a large amount of waste will be generated after the pump casing is milled. These wastes will fall from the slag outlet of the bottom cover 5 into the collection tank. Since a circular protrusion is provided in the middle of the collection plate 42, the fallen waste can be transferred to the side to avoid a large amount of debris accumulation, which will block the slag outlet above, and ensure that the continuously generated waste can be normally transferred to the collection tank for collection.

[0033] During the processing, or after the processing is completed, the waste on the collecting plate 42 can be quickly cleaned by pulling out the collecting plate 42 to avoid the accumulation of waste on the collecting plate 42, and the pump casing can be processed without stopping.

[0034] Reference Figure 7-9 , a pressure ring 11 is provided at the bottom of the bottom cover 5, and the pressure ring 11 is used to squeeze the clamping member 64, and the pressure ring 11 is fixedly connected to the inner wall of the processing table 4 through the elastic ring 10; The bottom plate 61 is an arc-shaped plate, and the upper side cross section is set as a circular protrusion. The four bottom plates 61 form a circular ring. The support assembly 7 is set inside the bottom plate 61, and the support assembly 7 is used to support the bottom cover 5; The support assembly 7 includes a liquid cavity 71, a contact strip 72 and an extrusion strip 73. The liquid cavity 71 is arranged inside the bottom plate 61, and a sliding opening communicating with the liquid cavity 71 is opened on one side of the bottom plate 61 close to the connecting shaft 62. The contact strip 72 is slidably arranged inside the sliding opening. The extrusion strip 73 is fixedly connected to the bottom end of the contact strip 72 and is sealingly slidably arranged inside the liquid cavity 71.

[0035] During the process of milling the pump casing by the milling actuator 33, since the pump casing is arranged vertically, when the inner keyway is opened, the milling actuator generates downward pressure on the pump casing, thereby completing the milling process. However, the multiple side clamps 64 cannot play an effective supporting and buffering effect in the vertical direction, which easily causes the surface of the milling position to be rough, affecting the subsequent processing of the pump casing.

[0036] After the pump casing to be processed is placed on the bottom cover 5, the weight of the pump casing itself will drive the bottom cover 5 to move downward, and the pressure ring 11 fixed under the bottom cover 5 will squeeze the bottom plate 61 during the downward movement. The multiple bottom plates 61 will play a vertical supporting role for the pump casing from below, and the bottom plate 61 will deflect downward, thereby driving the upper clamping member 64 to squeeze and contact the pump casing, thereby completing the horizontal clamping of the pump casing, and completing the clamping and fixing of the pump casing from both vertical and horizontal directions, thereby ensuring that the impact force of the vibration is dispersed during the processing.

[0037] When the pump body is first processed, due to the contact between the milling actuator 33 and the pump body, a large downward impact force will be generated, causing the entire processing table 4 to vibrate slightly. By pressing the contact strip 72 into the liquid cavity 71, the extrusion strip 73 squeezes the buffer solution inside the liquid cavity 71, thereby dispersing the impact force and achieving a buffering effect.

[0038] Through multi-directional limit fixation and support buffering at the bottom, the frequency of vibration during the milling process can be effectively reduced, the swing amplitude of the pump casing can be reduced, and the flatness of the inner keyway milling position can be ensured.

[0039] Reference Figure 7-9 The connecting shaft 62 includes a rotating shaft 621 and two connecting plates 622. The two connecting plates 622 are fixedly connected to the upper and lower sides of the rotating shaft 621. A positioning component 8 is provided between the connecting shaft 62 and the mounting port. The positioning assembly 8 includes a push piece 81, a slide rod 82, a positioning piece 83 and a positioning seat 84. A connecting cavity communicating with the liquid cavity 71 is opened inside the rotating shaft 621 and the lower connecting plate 622. An opening is opened on the side of the rotating shaft 621. The slide rod 82 is slidably arranged inside the opening. The push piece 81 is fixedly connected to one end of the slide rod 82 located inside the connecting cavity. The positioning piece 83 is fixedly connected to the other end of the slide rod 82. The positioning seat 84 is fixedly connected to the side wall of the installation port. Positioning teeth are provided on both the positioning piece 83 and the positioning seat 84. The upper end of the connecting cavity is set to be spherical, and the pushing piece 81 is a hemispherical elastic piece. The edge of the pushing piece 81 is fixedly connected to the inside of the connecting cavity. The hemispherical pushing piece 81 will divide the inside of the connecting cavity into a liquid guide space connected to the liquid cavity 71 and another part of the moving space. While squeezing the liquid, the sliding rod 82 can be retracted inward.

[0040] In the process of supporting the bottom cover 5, most of the weight of the pump casing is applied to the elastic ring 10 and the rotating shaft 621. By setting a supporting structure on the side of the rotating shaft 621, the load-bearing capacity of the rotating shaft 621 is enhanced to ensure support for the pump casing processing.

[0041] However, due to the movement of the milling actuator during the machining process, the pump casing will cause displacement and vibration, thereby causing the connecting shaft 62 to tilt and rotate, affecting the clamping effect of the multiple clamping parts 64 on the pump casing, so it is necessary to lock the position of the connecting shaft 62 during the milling process.

[0042] When the milling actuator 33 starts working, it will drive the extrusion bar 73 to squeeze the liquid inside the liquid chamber 71. After the liquid is impacted and squeezed, the push piece 81 at the upper end of the connecting chamber is squeezed, causing the push piece 81 to squeeze and push outward. The push piece 81 will drive the slide rod 82 to move outward, causing the positioning piece 83 to contact the positioning seat 84. The positioning teeth on the positioning piece 83 and the positioning seat 84 will contact and lock each other, thereby locking the connecting shaft 62 to prevent the connecting shaft 62 from deflecting and ensure the clamping effect on the pump casing.

[0043] Reference Figure 9 A plurality of position-limiting tension springs 9 are provided between the contact strip 72 and the positioning seat 84 , and the plurality of position-limiting tension springs 9 are used to limit the position of the contact strip 72 .

[0044] When the pump casing is placed, the limit spring 9 is used to pull the contact strip 72. At this time, the gravity of the pump casing cannot completely offset the upward pulling force of the limit spring 9 on the contact strip, so that the contact strip 72 supports the pump casing. When the keyway in the pump casing is milled, a continuous downward pressure is generated, thereby increasing the push on the contact strip 72. At this time, the gravity of the pump casing plus the downward pressure of the milling actuator 33 is greater than the pulling force of the limit spring 9, thereby pushing the contact strip 72 to move toward the inside of the liquid chamber, thereby completing the positioning of the positioning assembly 8 on the connecting shaft 62.

[0045] When milling is completed, the milling actuator 33 is separated from the pump casing, causing the force applied to the contact strip 72 to become smaller. At this time, the force acting on the contact strip 72 is only the gravity of the pump casing itself, which cannot offset the upward pulling force of the limit spring 9, thereby causing the limit spring 9 to drive the contact strip 72 to move upward, lifting the pump casing, and facilitating the unloading of the pump casing.

[0046] Moreover, before machining, the horizontal clamping force of the clamping assembly 6 on the pump body is relatively small due to the support of the contact strip 72. When the milling process begins, the pump casing is subjected to downward pressure, and the contact strip 72 moves downward, thereby causing the pump casing to move downward. The force acting on the support assembly 7 becomes greater, thereby increasing the horizontal clamping force on the pump casing. After the machining is completed, the clamping force is restored, making it easier to load and unload the pump casing.

[0047] The material and quantity of the limit spring 9 can be replaced according to the different volumes and specifications of the pump body. A large pump body is heavy and requires a limit spring 9 with a larger pulling force. A small pump body can use a limit spring 9 with a smaller pulling force. It can be adjusted according to different pump bodies to ensure the lifting of pump bodies of different specifications.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
