Description

Technical Field

[0001] This invention relates to the field of pump housing processing technology, and in particular to a jig for inclined drilling of pump housings. Background Technology

[0002] The pump casing is the main part that constitutes the working chamber of the pump. Together with the pump cover, it forms a closed space that houses rotor components such as the impeller, shaft, and rolling bearings. Pump casings include elbow casings, tubular casings, and volute casings, with tubular casings being the most common. After manufacturing, pump casings usually require additional processing, such as drilling and grinding.

[0003] The existing clamps extend from both sides to hold the pump housing at a fixed angle. When the pump housing needs to be drilled at an angle, these clamps are inconvenient to hold and cannot meet the tilting requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a pump housing tilt drilling fixture, which aims to solve the problem that existing fixtures have a fixed angle and cannot effectively meet the requirements of tilt drilling.

[0005] To achieve the above objectives, the present invention provides a pump housing tilting drilling fixture, comprising a machining box, a hanger, a first hydraulic rod, a drilling motor, a drilling cutter, a rotary motor, a rotating disk, and two clamping members. The hanger is fixed above the machining box; the first hydraulic rod is fixed below the hanger; the drilling motor is fixed at the output end of the first hydraulic rod; the drilling cutter is fixed at the output end of the drilling motor; the rotary motor is fixed in the machining box and located below the hanger; the rotating disk is fixed at the output end of the rotary motor; the two clamping members are fixed on both sides of the rotating disk; each clamping member includes a clamping arm, a first hydraulic rod, a second hydraulic rod, a third hydraulic rod, a fourth hydraulic rod, a fifth hydraulic rod, a sixth hydraulic rod, a seventh hydraulic rod, a scalpel ... The system comprises two hydraulic rods, a clamping seat, a herringbone slide rail, two clamping heads, two sliding rods, a third hydraulic rod, and a push plate. The herringbone slide rail has two grooves. The clamping arm is fixed to the rotating disk. The second hydraulic rod is fixed in the clamping arm. The clamping seat is located at the output end of the second hydraulic rod. The herringbone slide rail is fixed to the side of the clamping seat. The two sliding rods are slidably disposed in the two grooves of the herringbone slide rail. The two clamping heads are rotatably disposed on the two sliding rods. The third hydraulic rod is fixed to the side of the clamping seat and disposed in the herringbone slide rail. The push plate is fixed to the output end of the third hydraulic rod.

[0006] The clamping component further includes two magnetic blocks, which are disposed on the upper and lower sides of the push plate.

[0007] The pump housing tilting drilling fixture further includes an adjusting motor and an adjusting plate. The adjusting motor is disposed between the second hydraulic rod and the clamping seat, and its output end is fixedly connected to the clamping seat. The adjusting plate is rotatably disposed between another second hydraulic rod and the clamping seat.

[0008] The aforementioned pump housing tilting drilling fixture further includes a lifting motor, a first screw, a first limiting rod, a lifting platform, a deflection motor, a deflection arm, and a support plate. The lifting motor is fixed above the processing box; the first screw is fixed to the output end of the lifting motor; the first limiting rod is rotatably disposed on the side of the processing box near the first screw; the lifting platform is threadedly connected to the first screw and slidably connected to the first limiting rod; the deflection motor is fixed to the lifting platform; the deflection arm is fixed to the output end of the deflection motor; and the support plate is fixed to the deflection arm.

[0009] The pump housing inclined drilling fixture also includes a support plate, which is fixed on the lifting platform.

[0010] The pump housing tilting drilling fixture further includes a receiving motor, a second screw, a second limiting rod, and a receiving box. The receiving motor is fixed on the processing box; the second screw is fixed to the output end of the receiving motor; the second limiting rod is rotatably disposed in the processing box; the receiving box and the second screw are threadedly connected; and the receiving box is slidably connected to the second limiting rod.

[0011] The pump housing inclined drilling fixture also includes cushioning cotton, which is placed in the receiving box.

[0012] This invention discloses a pump housing tilting drilling fixture. The processing box is the main body of the entire device. The hanger is used to install the first hydraulic rod. After the first hydraulic rod extends, it controls the height of the drilling motor and the drilling cutter to achieve the feed action. The drilling motor is used to drive the drilling cutter to rotate, and the rotary motor is used to drive the rotary disk to rotate, thereby causing the two clamping members to rotate and rotate the pump housing at a certain angle for convenient tilting processing. The clamping arms of the clamping members are used to install the second hydraulic rod. After the second hydraulic rod extends, it drives the clamping seat to move. The side of the clamping seat is equipped with a herringbone slide rail. The herringbone slide rail is placed horizontally and is smaller than the inner diameter of the pump housing, allowing it to extend into the pump housing. The clamping head is installed into the slide groove of the herringbone slide rail via the slide rod. The third hydraulic rod is used to push out the push plate, thereby pushing the two clamping heads to move. In use, the tubular pump housing is placed between the two clamping seats, and then the second hydraulic rod is activated to push the two clamping seats towards each other. The slide rail extends into the pump housing. At this time, the two clamping heads are located at the narrower part of the herringbone slide rail and follow the herringbone slide rail into the pump housing. Then, the third hydraulic rod is activated, pushing out the push plate. The push plate squeezes the two clamping heads to the two ends of the herringbone slide rail fork, allowing them to extend from inside the pump housing to both sides and abut against the inner wall of the pump housing, clamping and fixing the pump housing from the inside. At this time, the push plate remains extended, which can support the clamping heads. The two second hydraulic rods can cooperate with each other to adjust the left and right position of the pump housing. Then, the rotary motor is activated, and the rotary disk drives the two clamping arms to rotate at a certain angle to facilitate tilting processing. Then, the first hydraulic rod and the drilling motor are activated to drill holes in the pump housing. This invention clamps and fixes the tubular pump housing from the inside through the clamping heads, exposing most of the outer surface of the pump housing, making the processing angle wider. Then, the rotating structure can effectively tilt the pump housing, thus solving the problem that the existing fixtures have fixed angles and cannot effectively meet the needs of tilting drilling.
