Description

Technical Field

[0001] This utility model relates to the field of pump body processing equipment technology, and in particular to a rotary processing table for processing pump bodies. Background Technology

[0002] As a core component of fluid transport systems, pump bodies typically have complex structures, often featuring irregular curved surfaces and multiple holes and flow channels requiring precise machining. The manufacturing process of pump bodies usually involves multiple machining steps, such as grinding and drilling.

[0003] Currently, when machining pump bodies, a fixed fixture is commonly used to clamp the pump body onto the machine tool table, and then different machining equipment is used to perform the work step by step. This traditional method has the following significant drawbacks:

[0004] Currently, due to the wide variety of pump body models and shapes, it is often necessary to design and manufacture special fixtures for specific pump body models. This not only increases production costs and preparation time, but also requires frequent replacement and readjustment of fixtures when switching to process different pump body models, resulting in prolonged equipment downtime and low production efficiency. Traditional rigid fixtures are difficult to ensure uniform distribution of clamping force when facing pump bodies with irregular curved surfaces, which can easily lead to low workpiece clamping and positioning accuracy. In fact, uneven force during clamping can even cause deformation or surface indentation, affecting the quality of subsequent processing. Moreover, after completing one process, the operator needs to unload the pump body from the current fixture, transfer it, and re-clamp it onto another machine for subsequent processing. This multiple clamping not only increases the labor intensity of workers, but also accumulates processing errors due to repeated positioning errors, making it difficult to guarantee the relative positional accuracy between various processing features.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary processing table for processing pump bodies includes an operating table, a platform rotatably connected to the top of the operating table, a storage slot on the top of the platform, and a functional box fixedly installed on the top of the platform. A grinder and a drill are respectively installed on the two sides of the top of the operating table. A rotary motor is fixedly installed at the bottom of the operating table, a drive gear is fixedly installed on the output shaft of the rotary motor, an external gear ring is fixedly installed on the outer side of the platform, and the drive gear meshes with the external gear ring. A drive motor is fixedly installed on one side of the platform, and the drive motor is connected to the two functional boxes. The table also includes...

[0008] An adaptive clamping mechanism is symmetrically arranged on one side of the two function boxes that are close to each other, and is connected through the function boxes;

[0009] An automatic locking mechanism is installed on the top of the function box and engages with the adaptive clamping mechanism for limiting.

[0010] Preferably, the adaptive clamping mechanism further includes multiple sealing grooves, which are respectively fixedly installed on the side of the two functional boxes that are close to each other. One end of the sealing groove extends into the functional box, and a top rod is slidably connected inside the sealing groove. An arc-shaped clamping plate is fixedly installed at one end of the top rod.

[0011] Preferably, an adjusting plate is slidably connected to the inner wall of the functional box, the adjusting plate is in contact with the inner wall of the functional box, a threaded rod is slidably connected to the side of the two functional boxes that are far apart from each other, the threaded rod is fixedly connected to the corresponding adjusting plate, and a rotating plate is rotatably connected to the side of the two functional boxes that are far apart from each other, the rotating plate is threadedly connected to the corresponding threaded rod.

[0012] Preferably, the automatic locking mechanism further includes multiple pins, which are slidably installed on the top of the corresponding sealing groove tubes, and the same connecting rod is fixedly installed on the multiple pins on the same side. Positioning seats are fixedly installed on the sides of the two functional boxes that are close to each other, and push rods are slidably connected to the positioning seats. The push rods are fixedly connected to the corresponding connecting rods.

[0013] Preferably, the positioning seat has a sliding cavity, a locking block is slidably connected to the inner wall of the sliding cavity, a plurality of beveled grooves are provided on one side of the push rod, the locking block is engaged with the beveled grooves, and two top springs are fixedly installed on one side of the inner wall of the sliding cavity, one end of the top spring is fixedly connected to the locking block, and a pull rod is fixedly installed on one side of the locking block, the pull rod passes through the positioning seat and is equipped with a protrusion.

[0014] Preferably, a pressure injection box is fixedly installed on the top of the functional box, a piston plate is slidably connected to the inner wall of the pressure injection box, a drive rod is fixedly installed on one side of the piston plate, a wedge-shaped pressure block is fixedly installed at one end of the drive rod, the wedge-shaped pressure block is pushed and cooperated with the corresponding push rod, and the pressure injection box is interconnected with the corresponding functional box.

[0015] Preferably, the top of the platform has two symmetrically arranged sliding grooves, the inner walls of the two sliding grooves are rotatably connected to the same bidirectional lead screw, the inner walls of the sliding grooves are slidably connected to a drive block, the drive block is fixedly connected to the corresponding functional box, and the bidirectional lead screw is threadedly connected to the two drive blocks and fixedly connected to the output shaft of the drive motor.

[0016] The advantages of the rotary machining table for processing pump bodies described in this utility model are as follows:

[0017] 1. The adaptive clamping mechanism, composed of multiple independently moving arc-shaped clamping plates, can automatically adjust the contact surface according to the irregular shape of the pump body, forming a "contour-following" fixture. This enables it to stably clamp pump bodies of different models or with slight manufacturing errors, greatly improving the versatility and flexibility of the equipment. The multi-point contact flexible clamping can better distribute the clamping force than traditional rigid fixtures, helping to prevent indentations or damage to the surface of precision or fragile workpieces.

[0018] 2. Pneumatic self-locking mechanism: The core innovation of this design lies in utilizing the air pressure changes generated within the functional box during clamping to automatically trigger the locking mechanism. Once clamped in place, the air pressure pushes the locking block into the top rod, rigidly locking the entire clamping system. This mechanical locking effectively prevents loosening or retraction of the clamping position during processing processes involving vibration and impact, such as grinding and drilling. This ensures the absolute stability of the workpiece during processing, thereby guaranteeing extremely high processing accuracy and consistency. Once the first workpiece is clamped and locked, the system will maintain this clamping state. It can quickly and continuously perform the same clamping operation on multiple pump bodies of the same specification without repeated adjustments, making it very suitable for mass production.

[0019] 3. Active pressure adjustment: By rotating the rotating plate, the adjustment plate can be moved to actively change the initial air pressure in the functional box. This allows the operator to precisely adjust the clamping force according to the material, structural strength or processing requirements of the workpiece, and achieve the best balance between "firm clamping" and "preventing overpressure damage".

[0020] 4. Workpiece rotation machining: The rotating platform allows the workpiece to be easily adjusted in angle, enabling the grinding machine and drilling machine to easily cover multiple sides of the pump body for multi-directional machining. The grinding machine and drilling machine are mounted on the lead screw module and have linear feed capability. Combined with the rotation of the workpiece, more complex trajectories and holes can be machined, expanding the processing capacity of the equipment.

[0021] This invention integrates functions such as adaptive clamping, pneumatic feedback locking, multi-station processing, and flexible adjustment into one unit. It not only significantly improves the efficiency, accuracy, and consistency of pump body processing, but also, due to its excellent versatility and automation level, can adapt to the diverse needs of small-batch, multi-variety and large-batch production. It is an ingeniously designed and highly practical intelligent manufacturing equipment. Attached Figure Description

[0030] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0031] Example 1

[0032] The following is combined with Figures 1-7 This application will be described in further detail.

[0033] A rotary processing table for processing pump bodies includes an operating table 1, a platform 2 rotatably connected to the top of the operating table 1, a storage slot 3 on the top of the platform 2, and a functional box 4 fixedly installed on the top of the platform 2. A grinder 14 and a drill 15 are respectively installed on the two sides of the top of the operating table 1. A rotary motor 11 is fixedly installed at the bottom of the operating table 1, and a drive gear 12 is fixedly installed on the output shaft of the rotary motor 11. An external gear ring 13 is fixedly installed on the outer side of the platform 2, and the drive gear 12 and the external gear ring 13 mesh with each other. A drive motor 9 is fixedly installed on one side of the platform 2, and the drive motor 9 is connected to the two functional boxes 4. An adaptive clamping mechanism 5 is symmetrically arranged on the side of the two functional boxes 4 that are close to each other and is in through communication with the functional boxes 4. An automatic locking mechanism 6 is installed on the top of the functional box 4 and cooperates with the adaptive clamping mechanism 5 for limiting.

[0034] Specifically, the grinding machine 14 and the drilling machine 15 are mounted on the operating table 1 via a lead screw module. The lead screw module drives the grinding machine 14 and the drilling machine 15 to move on the operating table 1 to perform multi-directional grinding and drilling operations on the pump body.

[0035] Reference Figure 4 and Figure 5 In this embodiment, the adaptive clamping mechanism 5 further includes multiple sealing groove tubes 51, which are respectively fixedly installed on the sides of the two functional boxes 4 that are close to each other. One end of the sealing groove tube 51 extends into the functional box 4. A top rod 52 is slidably connected inside the sealing groove tube 51. An arc-shaped clamping plate 53 is fixedly installed on one end of the top rod 52. An adjusting plate 54 is slidably connected to the inner wall of the functional box 4. The adjusting plate 54 is in contact with the inner wall of the functional box 4. Threaded rods 55 are slidably connected to the sides of the two functional boxes 4 that are far apart from each other. The threaded rods 55 are fixedly connected to the corresponding adjusting plates 54. Rotating plates 56 are rotatably connected to the sides of the two functional boxes 4 that are far apart from each other. The rotating plates 56 are threadedly connected to the corresponding threaded rods 55.

[0036] Specifically, the adaptive clamping mechanism, composed of multiple independently moving arc-shaped clamping plates 53, can automatically adjust the contact surface according to the irregular shape of the pump body to form a "contour" clamp. This enables it to stably clamp pump bodies of different models or with slight manufacturing errors, greatly improving the versatility and flexibility of the equipment.

[0037] Reference Figure 6In this embodiment, the automatic locking mechanism 6 further includes multiple pins 68, which are slidably mounted on the top of the corresponding sealing groove tubes 51. A common connecting rod 69 is fixedly mounted on the pins 68 on the same side. Positioning seats 61 are fixedly mounted on the sides of the two functional boxes 4 that are close to each other. Push rods 62 are slidably connected to the positioning seats 61, and the push rods 62 are fixedly connected to the corresponding connecting rods 69. A sliding cavity 63 is provided inside the positioning seat 61, and a locking block 64 is slidably connected to the inner wall of the sliding cavity 63. Multiple beveled grooves 65 are provided on one side of the push rod 62, and the locking block 64 engages with the beveled grooves 65. Two top springs 67 are fixedly installed on one side of the inner wall of the sliding cavity 63. One end of the top spring 67 is fixedly connected to the locking block 64. A pull rod 66 is fixedly installed on one side of the locking block 64. The pull rod 66 passes through the positioning seat 61 and is equipped with a protrusion. A pressure box 610 is fixedly installed on the top of the function box 4. A piston plate 611 is slidably connected to the inner wall of the pressure box 610. A drive rod 612 is fixedly installed on one side of the piston plate 611. A wedge-shaped pressure block 613 is fixedly installed on one end of the drive rod 612. The wedge-shaped pressure block 613 is pushed and engaged with the corresponding push rod 62. The pressure box 610 is interconnected with the corresponding function box 4.

[0038] Reference Figure 3 In this embodiment, the top of the platform 2 has two symmetrically arranged sliding grooves 7. The inner walls of the two sliding grooves 7 are rotatably connected to the same bidirectional lead screw 8. The inner walls of the sliding grooves 7 are slidably connected to the drive block 10. The drive block 10 is fixedly connected to the corresponding functional box 4. The bidirectional lead screw 8 is threadedly connected to the two drive blocks 10. The bidirectional lead screw 8 is fixedly connected to the output shaft of the drive motor 9.

[0039] In operation, when in use, the pump body is placed above the storage slot 3, and the drive motor 9 is turned on. The output shaft of the drive motor 9 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 is connected to the two drive blocks 10 by threads, which drives the two functional boxes 4 to move closer to each other. The two functional boxes 4 drive the top rod 52 and the arc-shaped clamping plate 53 to move through the sealing groove tube 51. Then, the pump body is clamped by the arc-shaped clamping plates 53 on both sides. At the same time, according to the different shapes of the pump body, multiple arc-shaped clamping plates 53 form different concave shapes, thus forming a clamp similar to the shape of the pump body. When the arc-shaped clamping plate 53 is concave, it pushes the top rod 52 to move into the functional box 4 and compresses the air in the functional box 4.

[0040] When it is necessary to adjust the clamping force, rotate the rotating plate 56. The rotating plate 56 is connected to the threaded rod 55 by a thread, which can drive the threaded rod 55 to move. The threaded rod 55 drives the adjusting plate 54 to move in the function box 4, which can squeeze the air pressure in the function box 4 and adjust the pushing force on the push rod 52.

[0041] When the air pressure inside the function box 4 increases, the gas inside the function box 4 is introduced into the injection box 610. The gas inside the injection box 610 pushes the piston plate 611 to move. The piston plate 611 drives the wedge-shaped pressure block 613 to move through the drive rod 612. The wedge-shaped pressure block 613 presses the push rod 62 to move downward. The push rod 62 drives the pin rod 68 to move downward through the connecting rod 69, thereby pressing and positioning the top rod 52, so that the multiple arc-shaped clamping plates 53 maintain their existing clamping state, thus enabling continuous clamping operation on multiple pump bodies of the same shape. At the same time, when the push rod 62 moves downward, the top spring 67 presses onto the angled groove 65 on the push rod 62 through the locking block 64, thereby forming a one-way lock, so that the push rod 62 can only move downward automatically and cannot move upward in the opposite direction. When it is necessary to release the fixation, pull the pull rod 66, so that the locking block 64 releases the locking of the push rod 62, thereby facilitating the reset of the arc-shaped clamping plate 53.

[0042] The rotary motor 11 drives the drive gear 12 to rotate. The drive gear 12 meshes with the external gear ring 13, thereby driving the platform 2 to rotate. This adjusts the processing position of the pump body, allowing the grinder 14 and the drill 15 to perform processing operations on different positions of the pump body, thus increasing the operating range.

[0043] Example 2

[0044] Example 2 is the same as Example 1 in the rest, except that: a gas nozzle is provided on the operating table 1 for cleaning the worktable 2 after processing, so as to maintain the best processing effect. All structural shapes, sizes and materials of Example 1 are included in this application. In order to meet specific use cases, they can be selected and adjusted. The attached drawings are schematic structural diagrams. The actual dimensions can be adjusted appropriately.

[0045] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
