Description

Technical Field

[0001] This application relates to the field of pump casing processing technology, and in particular to a fastening device for processing pump casings. Background Technology

[0002] Pump casing machining refers to a series of processing operations performed on the pump casing according to the pump's design requirements. This ensures the pump casing possesses the necessary mechanical properties, precision, and dimensional accuracy for proper pump operation. The pump casing typically encloses the pump's main components, serving a containment and protection function.

[0003] Referring to patent publication number CN221455669U, a fastening device for processing pump housings includes a base with two sliding grooves on the top. A drive motor is installed on one side of the base, and the output shaft of the drive motor passes through the inner wall of the base and is provided with a first bidirectional lead screw. One side of the first bidirectional lead screw is rotatably connected to one side of the inner wall of the base. First limiting rods are provided on both sides of the inner wall of the base. Two movable frames are externally threaded to the first bidirectional lead screw. Two connecting rods are provided on the top of each movable frame. The outer walls of the two connecting rods are slidably connected to the sliding grooves. The top of the two connecting rods is provided with a locking mechanism. The beneficial effect of this utility model is that the user turns on the drive motor by switching on the drive motor, and the drive motor drives the first bidirectional lead screw to rotate. The first bidirectional lead screw, through its external threads and the first limiting rods, drives the movable frames to move towards the center. The movement of the movable frames towards the center will move the locking blocks through the connecting rods, thereby fixing the housing.

[0004] While the above solution can fix the pump casing, it still has some shortcomings. For example, when fixing the pump casing, the clamping mechanism is in contact with the outer surface of the pump casing, which can obstruct the processing mechanism during the processing of the outer surface of the pump casing, thus affecting the processing efficiency of the pump casing.

[0005] To address this problem, we propose a fastening device for machining pump casings. Utility Model Content

[0006] The purpose of this application is to provide a fastening device for processing pump housings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fastening device for processing pump housings includes a carrier plate. A control panel is fixedly mounted on the upper surface of the carrier plate. A U-shaped plate is fixedly mounted on the bottom surface of the carrier plate. A motor is fixedly mounted on the bottom surface of the U-shaped plate. A threaded rod is fixedly mounted on the output end of the motor. A threaded tube is threadedly connected to the outer surface of the threaded rod. A control plate is fixedly mounted on the outer surface of the threaded tube. Two sets of control rods are rotatably mounted on the outer surface of the control plate via two sets of pins. Two sets of sliding grooves are fixedly mounted on the upper surface of the carrier plate. A perforated slider is slidably connected to the inner wall of each sliding groove. A top block is fixedly mounted on the upper surface of each perforated slider. The bottom surfaces of the two sets of perforated sliders are respectively hinged to the top ends of the two sets of control rods via two sets of pins. Two sliding rods are slidably connected to the inner wall of each perforated slider. The two ends of the two sets of sliding rods are respectively fixedly mounted to the inner walls of the two sets of sliding grooves.

[0009] In a further embodiment, a protective pad is provided above the carrier plate, and the bottom surface of the protective pad is fixedly installed to the upper surface of the carrier plate.

[0010] In a further embodiment, two sets of rubber pads are fixedly installed on the upper surface of the carrier plate, and the sides of the two sets of rubber pads that are close to each other are fixedly installed on the sides of the two sets of top blocks that are far from each other.

[0011] In a further embodiment, two fixing strips are fixedly installed on the bottom surface of the carrier plate, and the two fixing strips are fixedly installed on the left and right sides of the U-shaped plate respectively on their sides that are close to each other.

[0012] In a further embodiment, two sets of support legs are provided below the carrier plate, and the upper surface of each support leg is fixedly installed to the bottom surface of the carrier plate.

[0013] In a further embodiment, two partitions are fixedly installed on the inner wall of the U-shaped plate, and the two partitions are located on the left and right sides of the motor, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application, through the cooperation of a motor, a threaded rod, and a threaded tube, enables the threaded tube to push the control plate to move up and down, which in turn enables the control plate to push the bottom end of the control rod to move, which in turn enables the top end of the control rod to push the perforated slider to move along the slide groove. This causes the slider to move the top block away from each other, so that the top block contacts the inner wall of the workpiece and fixes the workpiece. This allows for smooth processing of the outer surface of the workpiece during machining, improving the processing efficiency of the pump housing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this utility model, a fastening device for processing pump casing includes a carrier plate 1. Two sets of rubber pads 10 are fixedly installed on the upper surface of the carrier plate 1. The side of the two sets of rubber pads 10 that are close to each other is fixedly installed on the side of the two sets of top blocks 11 that are far from each other. The rubber pads 10 can protect the pump casing and prevent scratches from appearing on the surface of the pump casing during fixing. A control panel 2 is fixedly installed on the upper surface of the carrier plate 1.

[0024] A U-shaped plate 3 is fixedly installed on the bottom surface of the carrier plate 1. Two partitions 5 are fixedly installed on the inner wall of the U-shaped plate 3. The two partitions 5 are located on the left and right sides of the motor 6, respectively. The partitions 5 can separate the motor 6, so that the space on both sides can prevent tools. Two fixing strips 13 are fixedly installed on the bottom surface of the carrier plate 1. The side of the two fixing strips 13 that are close to each other is fixedly installed on the left and right sides of the U-shaped plate 3, respectively. The fixing strips 13 can reinforce the U-shaped plate 3, increase the stability of the U-shaped plate 3, and prevent the U-shaped plate 3 from falling off.

[0025] Two sets of support legs 4 are provided below the carrier plate 1. The upper surface of each support leg 4 is fixedly installed to the bottom surface of the carrier plate 1. The support legs 4 can support the device and prevent the motor 6 from being hit. The motor 6 is fixedly installed on the bottom surface of the U-shaped plate 3. The output end of the motor 6 is fixedly installed with a threaded rod 7. The outer surface of the threaded rod 7 is threadedly connected to a threaded tube 8. The outer surface of the threaded tube 8 is fixedly installed with a control plate 14. The outer surface of the control plate 14 is rotatably installed with two sets of control rods 15 through two sets of pins.

[0026] Two sets of sliding grooves 9 are fixedly installed on the upper surface of the carrier plate 1. A protective pad 12 is provided above the carrier plate 1. The bottom surface of the protective pad 12 is fixedly installed on the upper surface of the carrier plate 1. The protective pad 12 protects the pump casing and prevents the pump casing from colliding with the carrier plate 1. A perforated slider 16 is slidably connected to the inner wall of each sliding groove 9. A top block 11 is fixedly installed on the upper surface of each perforated slider 16. The bottom surfaces of the two sets of perforated sliders 16 are respectively hinged to the top ends of the two sets of control rods 15 through two sets of pins. Two sliding rods 17 are slidably connected to the inner wall of each perforated slider 16. The two ends of the two sets of sliding rods 17 are respectively fixedly installed on the inner walls of the two sets of sliding grooves 9.

[0027] The working principle of this application is:

[0028] In use, the pump casing is placed outside the top block 11, and then the motor 6 is started. The motor 6 drives the threaded rod 7 to rotate, so that the threaded rod 7 engages with the threaded connection of the threaded tube 8, causing the threaded tube 8 to push the control rod 15 to move. This causes the bottom of the control rod 15 to move upward, which in turn causes the top of the control rod 15 to push the perforated slider 16. The perforated slider 16 moves along the direction of the slide rod 17, thereby causing the perforated slider 16 to move the top block 11 away from each other, so that the top block 11 contacts the inner wall of the pump casing, fixing the pump casing and preventing it from shaking.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
