Description

Technical Field

[0001] This application relates to the field of plunger hole machining technology, and more specifically, to a plunger hole machining fixture for a nine-hole disc. Background Technology

[0002] The nine-hole return plate, also known as a return plate, is typically made of metal. During pump operation, liquid enters the pump body through the inlet, is compressed by the plunger, and finally flows out through the outlet. The return plate controls the movement of the plunger, ensuring smooth operation. When the plunger moves forward, the return plate moves backward, allowing the liquid to flow smoothly. When the plunger moves backward, the return plate moves forward, allowing the liquid to flow smoothly back to the inlet.

[0003] The existing technology publication CN221735458U provides a tooling for machining plunger holes in a return plate. By contacting one side of the workpiece with a spring locating pin, causing the spring locating pin to elastically deform, the workpiece is placed on a boss, with the other side of the workpiece abutting against the locating pin. At this time, the spring locating pin deforms and rebounds, positioning the workpiece to the center of the boss. A pressure plate is placed against the workpiece, and then a clamping bolt is inserted through the pressure plate and engages with the mounting threaded hole to fix the workpiece. Through the above steps, the workpiece can be quickly clamped and positioned, which has the advantages of accurate positioning and firm clamping. It reduces vibration and deformation of the workpiece during processing, thereby ensuring product quality, reducing auxiliary time, lowering labor costs, and improving production efficiency.

[0004] Although the device has many beneficial effects, the following problems still exist: when drilling the return plate, it is difficult to adjust the drilling position according to the different sizes of return plates, making it difficult to drill return plates of different sizes, which in turn reduces the versatility of the tooling. In view of this, we propose a plunger hole machining tooling for nine-hole plates. Utility Model Content

[0005] This application provides a plunger hole machining fixture for nine-hole discs, which solves the technical problem in the prior art where it is difficult to adjust the drilling position according to different sizes of return discs when drilling return discs, thus making it difficult to drill return discs of different sizes and reducing the versatility of the fixture. It enables operators to easily adjust the position of the drill rod according to the size of the return disc, thereby facilitating the adjustment of the drilling position according to different sizes of return discs and expanding the versatility of the fixture in use.

[0006] This application provides a tooling for machining plunger holes for a nine-hole disc, including: a machining table;

[0007] A vertical plate is fixedly connected to one side of the top of the processing table. A three-jaw chuck is installed on one side of the vertical plate for clamping return plates of different sizes. A sliding plate is slidably connected to the other side of the top of the processing table. A drilling mechanism is provided on one side of the sliding plate.

[0008] The drilling mechanism includes a first motor mounted on one side of a slide plate. One end of the output shaft of the first motor is fixedly connected to a rotating plate. A slot is opened on one side of the rotating plate, and a movable block is slidably connected in the slot. A mounting plate is fixedly connected to one side of the movable block. A second motor is mounted on one side of the mounting plate. One end of the output shaft of the second motor is fixedly connected to a drill rod for drilling. A plurality of threaded grooves are opened on one side of the rotating plate, and a first threaded rod for cooperating with the threaded grooves is threadedly connected through one side of the mounting plate.

[0009] By adopting the above technical solution and setting up a drilling mechanism, when workers need to drill holes in the return plate, it is convenient for workers to adjust the position of the drill rod according to the different sizes of return plates, thereby facilitating drilling operations on return plates of different sizes and expanding the versatility of the tooling.

[0010] Optionally, a guide rod is fixedly connected inside the slot, and the movable block is slidably sleeved on the outside of the guide rod.

[0011] By adopting the above technical solution, when the staff pushes the mounting plate to move, and the mounting plate drives the movable block to move in the slot, the movable block moves along the direction of the guide rod, ensuring the straightness and stability of the movable block's movement. This, in turn, ensures the accuracy of the movement of the mounting plate, the second motor, and the drill rod, enabling the drill rod to be accurately moved to the designated position, thus achieving the effect of improving the accuracy of drill rod position adjustment.

[0012] Optionally, the top of the processing table is provided with a slide groove, and a slider is fixedly connected to the bottom of the slide plate, the slider being slidably connected within the slide groove.

[0013] By adopting the above technical solution, when the hydraulic cylinder drives the slide plate to move, the slider slides in the slide groove, which provides a stable guide for the movement of the slide plate, ensures the straightness of the slide plate movement, and enables the slide plate to drive the first motor, rotating plate, mounting plate, second motor and drill rod and other components to move smoothly and accurately.

[0014] Optionally, a connecting sleeve is fixedly connected to the other side of the top of the processing table, and a hydraulic cylinder is installed inside the connecting sleeve. One end of the output shaft of the hydraulic cylinder is fixedly connected to the other side of the slide plate.

[0015] By adopting the above technical solution, when the operator starts the hydraulic cylinder, the output shaft of the hydraulic cylinder extends and retracts, driving the slide plate to move, thereby providing power to the slide plate and the drilling mechanism connected to it, realizing the horizontal movement of the drilling mechanism.

[0016] Optionally, a crossbar is provided on one side of the slide, and a collection box for collecting the debris generated during drilling is detachably connected to one end of the crossbar.

[0017] By adopting the above technical solution, when the sliding plate moves and drives the drilling mechanism to drill the return plate, the collection box can move with the sliding plate to collect the drilling debris in a timely manner. In addition, the collection box is detachable, which makes it convenient for staff to clean up the debris, thus achieving the effect of convenient collection of drilling debris.

[0018] Optionally, a through hole is provided on one side of the slide plate, the crossbar is slidably connected in the through hole, and a limit plate is fixedly connected to the other end of the crossbar.

[0019] By adopting the above technical solution, when the slide plate moves continuously and causes the collection box to come into contact with the vertical plate, the collection box can move in the direction of the slide plate, preventing the collection box from making direct hard contact with the vertical plate and affecting the drilling operation of the return plate.

[0020] Optionally, a spring is fixedly connected to the side of the limiting plate near the crossbar, and one end of the spring is fixedly connected to the other side of the slide plate.

[0021] By adopting the above technical solution, when the collection box abuts against the vertical plate and moves towards the slide plate, the crossbar drives the limiting plate to move and pulls the spring. The spring undergoes elastic deformation, providing a certain buffer space for the collection box and preventing the collection box from colliding hard with the vertical plate, which would affect the drilling operation of the return plate. This achieves the effect of providing a buffer for the collection box.

[0022] Optionally, a cross plate is fixedly sleeved on the outside of the crossbar, and the cross plate is connected to the collection box through a second threaded rod.

[0023] By adopting the above technical solution and setting up a horizontal plate and a second threaded rod, when there is a lot of debris in the collection box, the staff can unscrew the second threaded rod to separate the collection box from the horizontal rod and the horizontal plate, making it convenient for the staff to remove the collection box and dump the debris inside.

[0024] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0025] 1. By setting up a drilling mechanism, when workers need to drill holes in return plates of different sizes, it is convenient for workers to adjust the position of the drill rod according to the size of the return plate, thereby facilitating the adjustment of the drilling position according to different sizes of return plates, and thus expanding the versatility of the tooling.

[0026] 2. By setting up a crossbar and a collection box, when the slide moves towards the vertical plate to drill the return plate, the collection box can move with the slide, so as to facilitate the collection of the debris generated during drilling and prevent the debris from being directly scattered on the surface of the processing table.

[0027] 3. By setting through holes, crossbars, limiting plates, and springs, the slide plate needs to be continuously moved during drilling. When the slide plate moves continuously and causes the collection box to come into contact with the vertical plate, the collection box will move towards the slide plate, thereby driving the crossbar and limiting plate to move. This causes the limiting plate to pull the spring, giving the collection box a certain buffer space and preventing the collection box from colliding hard with the vertical plate, which would affect the drilling operation on the return plate.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a tooling for machining plunger holes for a nine-hole disc. The tooling includes: a machining table 1;

[0036] A vertical plate 2 is fixedly connected to one side of the top of the processing table 1. A three-jaw chuck 4 for clamping return plates of different sizes is installed on one side of the vertical plate 2. A sliding plate 5 is slidably connected to the other side of the top of the processing table 1. A drilling mechanism 3 is provided on one side of the sliding plate 5.

[0037] The drilling mechanism 3 includes a first motor 31, which is mounted on one side of the slide plate 5. One end of the output shaft of the first motor 31 is fixedly connected to a rotating plate 32. A slot is opened on one side of the rotating plate 32, and a movable block 33 is slidably connected in the slot. A mounting plate 34 is fixedly connected to one side of the movable block 33. A second motor 36 is mounted on one side of the mounting plate 34. The model of both the first motor 31 and the second motor 36 is 130ZFMA1-0003CBNM. One end of the output shaft of the second motor 36 is fixedly connected to a drill rod 37 for drilling. Multiple threaded grooves are opened on one side of the rotating plate 32. A first threaded rod 35 for cooperating with the threaded grooves is threaded through one side of the mounting plate 34, which facilitates the operator to adjust the drilling position according to different sizes of return plates, thereby improving the versatility of the tooling.

[0038] Reference Figure 2 and Figure 4 A guide rod 38 is fixedly connected inside the slot, and the movable block 33 is slidably sleeved on the outside of the guide rod 38, so as to ensure that the movable block 33 can move along the direction of the guide rod 38 and prevent the movable block 33 from deviating during movement.

[0039] Reference Figure 1 and Figure 5 The top of the processing table 1 is provided with a slide groove, and the bottom of the slide plate 5 is fixedly connected to a slider 6. The slider 6 is slidably connected in the slide groove, so that the slide plate 5 can move horizontally along the direction of the slide groove.

[0040] Reference Figure 1 and Figure 2 A connecting sleeve 7 is fixedly connected to the other side of the top of the processing table 1. A hydraulic cylinder 8 is installed inside the connecting sleeve 7. One end of the output shaft of the hydraulic cylinder 8 is fixedly connected to the other side of the slide plate 5, so as to facilitate pushing the slide plate 5 to move, and thus facilitate drilling the return plate.

[0041] Reference Figure 1 and Figure 5 A crossbar 9 is provided on one side of the slide plate 5. One end of the crossbar 9 is detachably connected to a collection box 10 for collecting the debris generated during drilling, so as to prevent the debris generated during drilling of the return plate from falling directly onto the top of the processing table 1.

[0042] Reference Figure 1 and Figure 5A through hole is provided on one side of the slide plate 5, and the crossbar 9 is slidably connected in the through hole. Since the slide plate 5 needs to be continuously moved during the drilling operation, the collection box 10 is very likely to come into contact with the vertical plate 2. When the collection box 10 comes into contact with the vertical plate 2 and the slide plate 5 continues to move, the collection box 10 can move towards the slide plate 5, thereby giving the collection box 10 room to move and preventing it from affecting the drilling operation of the return plate.

[0043] Reference Figure 1 and Figure 5 The other end of the crossbar 9 is fixedly connected to a limiting plate 11. The size of the limiting plate 11 is larger than the size of the inner side of the through hole, so as to prevent the crossbar 9 from falling out of the through hole.

[0044] Reference Figure 1 and Figure 5 There are at least two crossbars 9, which enables the collection box 10 to move horizontally in a stable manner.

[0045] Reference Figure 1 and Figure 5 A spring 12 is fixedly connected to the side of the limiting plate 11 near the crossbar 9. One end of the spring 12 is fixedly connected to the other side of the slide plate 5. This allows the limiting plate 11 to pull the spring 12 when the collection box 10 moves toward the slide plate 5. When the collection box 10 moves away from the slide plate 5, the limiting plate 11 will squeeze the spring 12, thereby increasing the resistance when the collection box 10 moves and preventing the collection box 10 from moving arbitrarily.

[0046] Reference Figure 1 and Figure 5 A horizontal plate 14 is fixedly sleeved on the outside of the horizontal bar 9. The horizontal plate 14 is connected to the collection box 10 through the second threaded rod 13, so that the staff can quickly remove the collection box 10 to clean or dump the debris inside.

[0047] The implementation principle of a plunger hole machining tool for a nine-hole disc in this application embodiment is as follows: when the operator needs to perform drilling operation on the return disc, the three-jaw chuck 4 is used to clamp the return disc, and then the operator can adjust the position of the drill rod 37 according to the size of the return disc.

[0048] When the position of drill rod 37 needs to be adjusted, the operator can unscrew the first threaded rod 35 from one of the threaded grooves. Then, the operator can push the mounting plate 34 to move. The movement of the mounting plate 34 can drive the movable block 33 to move along the direction of the guide rod 38 in the slot, so that the mounting plate 34 can drive the second motor 36 and the drill rod 37 to move. When the drill rod 37 moves to the designated position, the first threaded rod 35 is screwed into the corresponding threaded groove to fix the mounting plate 34.

[0049] Next, the operator can activate the hydraulic cylinder 8 to move the slide plate 5. The movement of the slide plate 5 can move the first motor 31, which in turn can move the rotating plate 32. The movement of the rotating plate 32 can move the mounting plate 34, which in turn can move the second motor 36 and the drill rod 37. Then, the second motor 36 is activated to rotate the drill rod 37, thereby drilling a hole in the return plate. After drilling a hole, the hydraulic cylinder 8 is used to move the slide plate 5 away from the vertical plate 2, which causes the slide plate 5 to move the drilling mechanism 3, thus separating the drill rod 37 from the return plate.

[0050] Subsequently, the staff can start the first motor 31 to drive the rotating plate 32 to rotate. The rotation of the rotating plate 32 can drive the movable block 33, the mounting plate 34, the second motor 36 and the drill rod 37 to rotate, which facilitates the drilling operation at the next position until all nine holes of the return plate are drilled.

[0051] Similarly, when drilling the return plate, the slide plate 5 needs to move continuously, so that the drill rod 37 can move continuously to complete the drilling operation. When the slide plate 5 moves, it can drive the collection box 10 to move through the crossbar 9 and the horizontal plate 14. When the slide plate 5 moves continuously and causes the collection box 10 to abut against the vertical plate 2, the collection box 10 will move in the direction of the slide plate 5 and drive the crossbar 9 to move in the through hole. The movement of the crossbar 9 can drive the limit plate 11 to move and pull the spring 12, thereby giving the collection box 10 a certain buffer space to prevent it from affecting the drilling operation of the return plate.

[0052] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. Those skilled in the art can connect all electrical components in this case to their compatible power supplies via wires. Appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described above, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art, therefore, electrical control will not be described further.
