Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a lifting and quenching water device for precision machining. Background Technology

[0002] In the field of machinery manufacturing, the performance of mechanical parts directly determines the overall quality and reliability of mechanical equipment. Water quenching, as an important heat treatment process, plays a crucial role in improving the microstructure and properties of metallic materials. With the continuous development of the precision machining industry, the requirements for the precision, hardness, wear resistance, and other properties of parts are increasingly stringent.

[0003] In the traditional water quenching process, workers immerse the workpieces to be quenched one by one in the water using a fixture, and then take them out one by one. When producing a large number of mechanical workpieces, the efficiency of water quenching is greatly reduced when a large number of workpieces are subjected to the water quenching process, while increasing the workload of workers. To address these issues, a lifting water quenching device for precision machining has been designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lifting and quenching water device for precision machining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lifting and quenching device for precision machining includes a base plate. Hydraulic push rods are fixedly connected to both ends of one side of the top of the base plate. The extension and retraction of the two hydraulic push rods allows for the raising and lowering of a lifting frame. A U-shaped lifting plate is fixedly connected to the top of the two hydraulic push rods. Strip plates are fixedly connected to both ends of the U-shaped lifting plate. T-shaped grooves are formed at the bottom of both strip plates, and T-shaped plates are slidably connected within these grooves. Rotary rods are rotatably connected to the top of the adjacent sides of the two T-shaped plates. A lifting frame is fixedly connected between the two rotary rods, and gears are fixedly fitted onto the circumferential surfaces of both rotary rods. L-shaped rods with racks are fixedly connected to the bottom of the two strip plates at their adjacent sides, with each L-shaped rod meshing with the adjacent gear. Through the interaction of the L-shaped rods and gears, the lifting frame automatically tilts and unloads the workpiece when it approaches a collection frame, pouring it into the collection frame for collection.

[0007] Preferably, the lifting frame has a discharge port on the side away from the U-shaped lifting plate, and the top of the discharge port is rotatably connected to the same rotating plate. Guide rods are fixedly connected to the bottom sides of the two T-shaped plates that are far apart from each other.

[0008] Preferably, a quenching tank is fixedly connected to the top of the base plate, and bending plates are fixedly connected to both sides of the inner wall of the quenching tank. Irregular holes are opened on both bending plates.

[0009] Preferably, the two guide rods are slidably connected in adjacent irregular holes. The irregular holes include vertical holes and inclined holes. The top of the vertical hole is connected to the bottom of the inclined hole. Through the cooperation of the irregular holes and the guide rods, when the two T-shaped plates lift the lifting frame, they will move according to the shape of the irregular holes, which makes it easier to bring the workpiece in the lifting frame out of the quenching tank.

[0010] Preferably, a drain pipe is fixedly connected to the bottom of the outer wall of the quenching tank near the hydraulic push rod, and a control valve is provided on the drain pipe. The drain pipe and the control valve make it easy to replace the water inside the quenching tank.

[0011] Preferably, a collection frame is fixedly connected to the side of the outer wall of the quenching tank away from the hydraulic push rod, and the collection frame is adapted to the lifting frame. Both ends of the bottom of the collection frame near the quenching tank are fixedly connected to reinforcing plates, and both reinforcing plates are fixedly connected to the quenching tank. The setting of the reinforcing plates improves the stability of the collection frame. The collection frame can collect the workpiece in the lifting frame, which is convenient for users to collect.

[0012] Preferably, support legs are fixedly connected to the four corners of the bottom of the base plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing technologies such as hydraulic push rods, U-shaped lifting plates, strip plates, L-shaped rods with racks and pinions, T-shaped plates, guide rods with irregular holes, lifting frames, and gears, the workpiece can be directly placed into the lifting frame in the quenching tank through the control of the hydraulic push rods. Alternatively, the lifting frame can be positioned at the top of the quenching tank, and the workpiece can be placed completely before entering the quenching tank. The timing of the workpiece entering the quenching tank is precisely controlled. Simultaneously, the extension of the hydraulic push rod causes the workpiece inside the lifting frame to automatically rise with the lifting frame and tilt into the collection frame. This effectively solves the problem of low quenching efficiency mentioned in the background technology, thereby reducing the cumbersome manual assistance steps and waiting time in traditional operations. The workpiece can complete the quenching process within the optimal time according to requirements, avoiding workpiece performance defects caused by excessively long or short quenching times, improving the product qualification rate and quality stability, and also achieving the technical effect of automated collection of workpieces after quenching.

[0015] 2. The inclusion of a drain pipe and control valve facilitates water replacement within the quenching tank, enhancing its practicality.

[0016] 3. The collection frame and reinforcing plate enable unified collection of workpieces in the lifting frame, making it convenient for users and improving work efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A lifting and quenching device for precision machining includes a base plate 1. Hydraulic push rods 3 are fixedly connected to both ends of one side of the top of the base plate 1. A U-shaped lifting plate 301 is fixedly connected to the top of the two hydraulic push rods 3. Strip plates 6 are fixedly connected to both ends of the U-shaped lifting plate 301. T-shaped grooves 601 are formed at the bottom of both strip plates 6. T-shaped plates 7 are slidably connected to both T-shaped grooves 601. Rotating rods 802 are rotatably connected to the top of the adjacent sides of the two T-shaped plates 7. The two rotating rods 802 are positioned between... The same lifting frame 8 is fixedly connected, and gears 803 are fixedly fitted on the circumferential surfaces of the two rotating rods 802. At the bottom of the two strip plates 6, one end away from the U-shaped lifting plate 301, and the other side is close to each other, a rack-and-pinion L-shaped rod 602 is fixedly connected. Each rack-and-pinion L-shaped rod 602 is adapted to the adjacent gear 803. The cooperation between the rack-and-pinion L-shaped rod 602 and the gear 803 causes the lifting frame 8 to move and tilt when it approaches the collection frame 4, pouring the workpiece in the lifting frame 8 into the collection frame 4.

[0024] In this utility model, the lifting frame 8 has a discharge port on the side away from the U-shaped lifting plate 301, and the top of the discharge port is rotatably connected to the same rotating plate 801. The bottom sides of the two T-shaped plates 7 are fixedly connected to guide rods 701. The cooperation between the guide rods 701 and the irregular hole 501 makes the T-shaped plate 7 move along the trajectory of the irregular hole 501 when it lifts the lifting frame 8.

[0025] In this utility model, a quenching tank 2 is fixedly connected to the top of the base plate 1, and bending plates 5 are fixedly connected to both sides of the inner wall of the quenching tank 2. The two bending plates 5 are provided with irregular holes 501.

[0026] In this utility model, two guide rods 701 are slidably connected in adjacent irregular holes 501. The irregular hole 501 includes a vertical hole and an oblique hole. The top of the vertical hole is connected to the bottom of the oblique hole. By setting the irregular hole 501, the lifting frame 8 will move towards the side of the collection frame 4 after leaving the quenching tank 2 when it rises with the T-shaped plate 7.

[0027] In this utility model, a drain pipe 201 is fixedly connected to the bottom of the outer wall of the quenching tank 2 near the hydraulic push rod 3, and a control valve 202 is provided on the drain pipe 201. The drain pipe 201 and the control valve 202 facilitate the discharge of water inside the quenching tank 2 and facilitate the replacement of water in the quenching tank 2.

[0028] In this utility model, a collection frame 4 is fixedly connected to the side of the outer wall of the quenching tank 2 away from the hydraulic push rod 3, and the collection frame 4 is adapted to the lifting frame 8. The collection frame 4 can collect the workpieces that have been quenched in the lifting frame 8. Both ends of the bottom of the collection frame 4 near the quenching tank 2 are fixedly connected to reinforcing plates 401, and both reinforcing plates 401 are fixedly connected to the quenching tank 2. The reinforcing plates 401 can improve the stability of the collection frame 4.

[0029] In this utility model, support legs 101 are fixedly connected to the four corners of the bottom of the base plate 1.

[0030] Working principle: During use, close the control valve 202 to inject an appropriate amount of water into the quenching tank 2. The lifting frame 8 is located inside the quenching tank 2, and since both rotating rods 802 are located at the top outer side of the lifting frame 8, the lifting frame 8 is in a stable state. Place the workpiece to be quenched into the lifting frame 8, ideally in the middle of the frame. Multiple workpieces can be placed in the lifting frame 8. Alternatively, the lifting frame 8 can be positioned at the top of the quenching tank 2. By controlling the retraction of the hydraulic push rod 3, the workpiece to be quenched descends with the lifting frame 8 into the quenching tank 2. After quenching, when retrieving the workpiece, simultaneously extend the two hydraulic push rods 3. The U-shaped lifting plate 301 rises, causing the two strip plates 6, along with the T-shaped plate 7, the lifting frame 8, and the workpiece, to rise together. During the process, the guide rod 701 slides in the irregular hole 501. Initially, the guide rod 701 slides in the vertical hole of the irregular hole 501, causing the lifting frame 8 to rise until the bottom of the lifting frame 8 is completely separated from the quenching tank 2. Then, the guide rod 701 will slide into the inclined hole of the irregular hole 501, causing the T-shaped plate 7 to slide in the T-shaped groove 601. The two T-shaped plates 7, along with the lifting frame 8, move closer to one side of the collection frame 4. When the T-shaped plate 7 slides to the end, the bottom of each gear 803 will mesh with the rack of the adjacent rack-and-pinion L-shaped rod 602. As the T-shaped plate 7 continues to move with the lifting frame 8, the two rotating rods 802 will rotate under the action of the gears 803, causing one side of the rotating plate 801 of the lifting frame 8 to tilt downward. At this time, the workpiece inside the lifting frame 8 will fall from the rotating plate 801 into the collection frame 4 for collection, improving the collection efficiency of the quenched workpiece.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
