Description

Technical Field

[0001] This invention relates to the field of gear pump processing, and more specifically to an internal liquid spraying mechanism for cutting aluminum billets in a pump. Background Technology

[0002] Gear pumps are widely used in industry for transporting liquids such as water and oil. Vehicle-mounted gear pumps can transmit pressure to the transmission fluid. The more complex shapes of the inner and outer walls of gear pumps are generally machined using industrial machine tools and cutting tools. Before this, the production of gear pumps requires the production of a large number of semi-finished blanks, which have the main shape of a gear pump and ensure that there is an axial through cavity to accommodate a pair of tangential gears.

[0003] The finished product upstream of this semi-finished blank for a single gear pump is a long aluminum profile. Some of these aluminum profiles are made by drawing aluminum dies and need to be cut one by one. Cutting often requires the use of a saw.

[0004] The sawing process generates a large amount of metal chips and high temperatures. Since aluminum profiles and blanks have an axial through cavity, metal chips tend to accumulate when they fall into the axial through cavity, which has some negative impacts on the subsequent cutting of aluminum profiles. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide an internal liquid spraying mechanism for the aluminum billet cutting operation of a pump. It is designed with an insert nozzle that sprays liquid in a rotating manner into the hollow cavity of the aluminum profile, which can promptly remove the metal debris generated during cutting and facilitate each sawing operation of the aluminum billet by the pump.

[0006] To solve the above problems, the present invention provides an internal liquid spraying mechanism for aluminum billet cutting operations using a pump. To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problems is as follows:

[0007] An internal spraying mechanism for aluminum billet cutting operations using a pump includes: a roller section comprising four butterfly wheels, each butterfly wheel having a convex curved surface, with the convex curved surfaces of two coaxial butterfly wheels coinciding with the same spatial spherical surface; a spraying component, the four butterfly wheels being movably connected via a connecting block, the spraying component including a main rod section, the main rod section being connected to a plurality of annular array nozzle rods, the nozzle rods being tangentially connected to a straight rod section; a water delivery rod communicating with the main rod section of the spraying component, the liquid in the water delivery rod being sprayed out from the nozzle rods of the spraying component; the main rod section of the spraying component being movably assembled with the connecting block, the spraying component having rotational freedom around its own axis; and the roller section contacting the inner wall of the axially penetrating cavity of the aluminum profile.

[0008] The beneficial effects of adopting the above technical solution are as follows: This technical solution features a specially designed liquid spraying mechanism that sprays liquid from the inside out for sawing operations with a long pump body at half cost. The sprayed liquid can be cutting fluid, which facilitates internal cooling of the aluminum profile and also removes a large amount of metal debris accumulated in the axial through-cavity. Clearing the metal debris facilitates subsequent sawing operations and avoids negative interference from metal debris.

[0009] Because the nozzle rods are arranged tangentially, the water spraying component uses the recoil force of the sprayed liquid to automatically rotate. The rotating water spraying component allows the liquid to be sprayed more evenly onto the inner wall of the axially penetrating cavity, improving uniformity.

[0010] In addition, the roller section consisting of four butterfly wheels is particularly suitable for the waist-shaped cross-sectional profile of the axial through cavity. The butterfly wheels can roll in the axial through cavity to adjust the specific position of the water sprayer, avoid interference between the water sprayer and the saw, and at the same time spray liquid on the nearby cutting seam. Metal chips are generated by the cutting operation and naturally accumulate in large quantities near the cutting seam.

[0011] The water delivery rod is connected to the sprinkler unit to deliver liquid. It can be adapted to long aluminum profiles and can also drive the rollers to move.

[0012] As a further improvement of the present invention, all nozzle rods and the axis of the main rod are at equal acute angles.

[0013] The beneficial effects of adopting the above technical solution are: the nozzle rod has a certain forward extension effect, which has a good flushing and removal effect on the metal debris on the cutting seam in front.

[0014] As a further improvement of the present invention, the angle between the nozzle rod and the axis of the main rod is greater than 65° and less than 85°.

[0015] The beneficial effect of adopting the above technical solution is that the included angle is a relatively large acute angle, which ensures that the recoil force is sufficient for the water spray component to rotate.

[0016] As a further improvement of the present invention, the number of nozzle rods is three.

[0017] The beneficial effect of adopting the above technical solution is that the three nozzle rods can spray evenly enough.

[0018] As a further improvement of the present invention, the connecting block has a through hole, and the two ends of the through hole are respectively assembled with the main rod and the water conveying rod.

[0019] The beneficial effects of adopting the above technical solution are: the through hole and the water conveying rod are sealed together, and the through hole and the main rod are sealed together to ensure rotation capability.

[0020] As a further improvement of the present invention, one end of the water conveying rod extends into the axial through cavity of the aluminum profile, and the other end of the water conveying rod is located outside the axial through cavity of the aluminum profile.

[0021] The beneficial effect of adopting the above technical solution is that the protruding end of the water conveying rod makes it convenient for personnel to drive the roller part to change its position.

[0022] As a further improvement of the present invention, the cross-sectional profile of the axial through cavity is waist-shaped, and the radius of curvature of the butterfly wheel convex surface is equal to half the width of the axial through cavity itself.

[0023] The beneficial effect of adopting the above technical solution is that the butterfly wheel adapts to the inner wall of the axial through cavity, avoiding shaking inside the aluminum profile.

[0024] As a further improvement of the present invention, the radial distance from the top of the nozzle rod to the axis of the main rod itself is less than the radius of curvature of the convex surface of the butterfly wheel.

[0025] The beneficial effect of adopting the above technical solution is that the rotating water spraying component will not touch the inner wall of the axially penetrating cavity.

[0026] As a further improvement of the present invention, the two coaxial butterfly wheels are connected to each other by a pin, which passes through the connecting block.

[0027] The beneficial effects of adopting the above technical solution are: the pin shaft ensures the rotational freedom of the disc wheel, and the connecting block provides assembly positions for each part. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to specific embodiments:

[0036] To achieve the objectives of this invention, an internal spraying mechanism for aluminum billet cutting operations in a pump includes: a roller section 2 comprising four butterfly wheels 3, each butterfly wheel 3 having a convex curved surface, and the convex curved surfaces of two coaxial butterfly wheels 3 coinciding with the same spatial spherical surface; and a spraying component 5, the four butterfly wheels 3 being movably connected by a connecting block 4, the spraying component 5 including a main rod section, the main rod section being connected to a plurality of annularly arrayed nozzle rods 6, such as... Figure 1 As shown, the nozzle rod 6 is tangentially connected to the straight rod portion; the water delivery rod 1 is connected to the main rod portion of the sprinkler component 5, and the liquid in the water delivery rod 1 is sprayed out from the nozzle rod 6 of the sprinkler component 5; the main rod portion of the sprinkler component 5 is movably assembled with the connecting block 4, and the sprinkler component 5 has a degree of rotational freedom around its own axis; the roller portion 2 is in contact with the inner wall of the axial through cavity 10 of the aluminum profile 9.

[0037] like Figure 1 It can be seen that the axis of the nozzle rod 6 does not intersect with the axis of the main rod.

[0038] The water sprayer 5 sprays out cutting fluid.

[0039] The beneficial effects of adopting the above technical solution are as follows: This technical solution features a specially designed liquid spraying mechanism that sprays liquid from the inside out for sawing operations with long pump bodies at half cost. The sprayed liquid can be cutting fluid, which facilitates internal cooling of the aluminum profile and removes a large amount of metal debris accumulated in the axial through-cavity. Clearing the metal debris facilitates subsequent sawing operations and avoids negative interference from metal debris. Because the nozzle rod is tangentially arranged, the spraying component automatically rotates using the recoil force of the spray. The rotating spraying component allows the liquid to be sprayed more evenly onto the inner wall of the axial through-cavity, improving uniformity. Furthermore, the roller section composed of four butterfly wheels is particularly suitable for the waist-shaped cross-sectional profile of the axial through-cavity. The butterfly wheels can roll within the axial through-cavity, adjusting the specific position of the spraying component and avoiding interference between the spraying component and the saw. It can also spray liquid onto the nearby cutting kerf, where metal debris, generated during the cutting operation, naturally accumulates in large quantities. The water delivery rod is connected to the sprinkler unit to deliver liquid. It can be adapted to long aluminum profiles and can also drive the rollers to move.

[0040] In other embodiments of the invention, all nozzle rods 6 form an equal acute angle with the axis of the main rod itself.

[0041] The beneficial effects of adopting the above technical solution are: the nozzle rod has a certain forward extension effect, which has a good flushing and removal effect on the metal debris on the cutting seam in front.

[0042] In other embodiments of the present invention, the angle between the nozzle rod 6 and the axis of the main rod is greater than 65° and less than 85°.

[0043] The beneficial effect of adopting the above technical solution is that the included angle is a relatively large acute angle, which ensures that the recoil force is sufficient for the water spray component to rotate.

[0044] In other embodiments of the invention, the number of nozzle rods 6 is three.

[0045] The beneficial effect of adopting the above technical solution is that the three nozzle rods can spray evenly enough.

[0046] In other embodiments of the invention, such as Figure 3 As shown, the connecting block 4 has a through hole 8, and the two ends of the through hole 8 are respectively assembled with the main rod and the water conveying rod 1.

[0047] The beneficial effects of adopting the above technical solution are: the through hole and the water conveying rod are sealed together, and the through hole and the main rod are sealed together to ensure rotation capability.

[0048] In other embodiments of the invention, such as Figure 4 As shown, one end of the water supply rod 1 extends into the axial through cavity 10 of the aluminum profile 9, and the other end of the water supply rod 1 is located outside the axial through cavity 10 of the aluminum profile 9.

[0049] The beneficial effect of adopting the above technical solution is that the protruding end of the water conveying rod makes it convenient for personnel to drive the roller part to change its position.

[0050] In some other embodiments of the present invention, the cross-sectional profile of the axial through cavity 10 is waist-shaped, and the radius of curvature of the convex surface of the butterfly wheel 3 is equal to half the width of the axial through cavity 10 itself.

[0051] The beneficial effect of adopting the above technical solution is that the butterfly wheel adapts to the inner wall of the axial through cavity, avoiding shaking inside the aluminum profile.

[0052] In some other embodiments of the present invention, the radial distance from the top of the nozzle rod 6 to the axis of the main rod itself is less than the radius of curvature of the convex surface of the butterfly wheel 3.

[0053] The beneficial effect of adopting the above technical solution is that the rotating water spraying component will not touch the inner wall of the axially penetrating cavity.

[0054] In other embodiments of the present invention, two coaxial butterfly wheels 3 are connected to each other by a pin, which passes through the connecting block 4.

[0055] The beneficial effects of adopting the above technical solution are: the pin shaft ensures the rotational freedom of the disc wheel, and the connecting block provides assembly positions for each part.

[0056] One end of the main rod of the sprinkler component 5 is the water inlet 7, and the sprinkler component 5 is a one-piece copper component.

[0057] like Figure 5 As shown, during use, this mechanism passes through the axial through cavity 10 of the aluminum profile 9, and the saw 11 on the sawing machine cuts the aluminum profile 9 into sections, cutting out individual pump aluminum billets 12. This mechanism always retracts slightly to prevent the saw 11 from cutting it, but always stays close to the cutting seam 13 to ensure that the metal debris generated at the cutting seam 13 can be sprayed.

[0058] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
