Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for processing marine motor covers. Background Technology

[0002] In the field of shipbuilding and repair, the machining accuracy and surface quality of marine motor covers have a significant impact on the performance and reliability of motors. As a key piece of process equipment ensuring machining accuracy, the design rationality and functionality of machining fixtures are crucial. Currently, the fixtures used in the machining of marine motor covers primarily focus on the stable clamping of the motor cover to meet the positioning and fixing requirements of cutting, drilling, and other machining operations.

[0003] Existing motor cover machining fixtures, such as the fixture disclosed in CN216829702U for milling the end face of marine hatch covers, employ a clamping device. The hatch cover is placed between clamping plates, and the four clamping plates work together to fix and hold the hatch cover. The clamping effect is good. However, the above-mentioned clamping device does not include a cutting fluid and debris recovery and filtration device, which causes cutting fluid and debris to enter the clamping device through the sliding groove used to move the connecting rod, affecting the accuracy and service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing clamping devices that do not include a cutting fluid and debris recovery and filtration device, which causes cutting fluid and debris to enter the clamping device through the sliding groove used for moving the connecting rod, affecting the accuracy and service life of the equipment. Therefore, this invention proposes a clamping fixture for machining marine motor covers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixture for machining marine motor covers includes a mounting base. The top of the mounting base has a receiving groove, and the top of the outer wall of the receiving groove has a mounting hole. A filter hopper for primary filtration of debris is fixedly installed in the mounting hole by bolts. A fixing block is fixedly connected to the middle of the inner wall of the receiving groove. A filter disc for secondary filtration of debris is slidably connected to the fixing block. The bottom of the receiving groove has a circular groove for guiding the concentration of cutting fluid. Both ends of the circular groove pass through the outer wall of the mounting base and are connected to a drain port. A clamping assembly is provided at the bottom of the mounting base.

[0006] Preferably, the outer wall of the filter bucket has a first threaded hole coaxial with the mounting hole, and the mounting base is fixedly connected by bolts passing through the mounting hole and threadedly connected to the threaded hole on the filter bucket.

[0007] Preferably, a rectangular groove is formed at the bottom of the outer wall of the filter disc, the rectangular groove is slidably engaged with the fixing block, and the filter disc is disposed below the filter hopper.

[0008] Preferably, the clamping assembly includes a mounting groove and a rectangular slide groove formed at the bottom of the mounting base. A servo motor is fixedly installed on the bottom of the inner wall of the mounting groove. A bevel gear one is fixedly connected to the output end of the servo motor. A threaded rod is rotatably connected in the rectangular slide groove. A bevel gear two is fixedly connected to one end of the threaded rod located in the mounting groove.

[0009] Preferably, a 1 / 2-shaped movable rod is slidably connected within the rectangular groove, a second threaded hole is provided at one end of the bottom of the movable rod, and a spring resistance trigger clamp is fixedly installed at one end of the top of the movable rod.

[0010] Preferably, a rectangular frame is fixedly connected to the top of the mounting base, the rectangular frame slides with the outer wall of the movable rod, and the threaded rod is threadedly connected to the second threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In use, this utility model can achieve dual filtration of cutting fluid and debris by setting a filter bucket and a filter disc on the top of the mounting base. The filter bucket can initially intercept larger debris, while the filter disc performs secondary filtration on smaller debris, effectively preventing debris from entering the clamping device. At the same time, the circular groove and drain port design at the bottom of the collection tank can guide the cutting fluid to concentrate and discharge smoothly, facilitating recycling and reuse, and improving resource utilization.

[0012] 2. In use, this utility model utilizes a clamping assembly located at the bottom of the mounting base. A servo motor drives bevel gear one and bevel gear two, which in turn rotate the threaded rod, allowing the moving rod to slide within the rectangular groove. Combined with a spring-resistance trigger clamping plate, it can stably clamp the marine motor cover. Furthermore, the clamping assembly, located at the bottom, effectively intercepts debris, preventing it from entering the clamping device through the groove used for moving the connecting rod. This reduces wear on the precision components inside the equipment, prevents equipment malfunctions caused by debris accumulation, and thus ensures the processing accuracy of the equipment, extends its service life, and reduces maintenance costs.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 A fixture for machining marine motor covers includes a mounting base 1. The top of the mounting base 1 has a receiving groove 2. The top of the outer wall of the receiving groove 2 has a mounting hole 3. A filter hopper 4 for primary filtration of debris is fixedly installed in the mounting hole 3 by bolts. A fixing block 5 is fixedly connected to the middle of the inner wall of the receiving groove 2. A filter disc 6 for secondary filtration of debris is slidably connected to the fixing block 5. A circular groove 7 for guiding the concentration of cutting fluid is opened at the bottom of the receiving groove 2. The circular groove 7 is semi-circular in shape and inclined towards the drain port 8. This unique structural design can utilize the principle of gravity to naturally guide the cutting fluid in the receiving groove 2 into the circular groove 7 and discharge it through the drain port 8. The two ends of the circular groove 7 pass through the outer wall of the mounting base 1 and are connected to the drain port 8. The drain port 8 adopts a standard interface design and can be directly connected to an external cutting fluid recovery device to realize centralized recovery and treatment of cutting fluid, effectively reduce environmental pollution, and reduce production costs. The bottom of the mounting base 1 is provided with a clamping component 9.

[0017] The outer wall of the filter bucket 4 is provided with a first threaded hole 10 coaxially arranged with the mounting hole 3. The unique conical structure design of the filter bucket 4 increases the filtration area and avoids clogging. The mounting base 1 is fixedly connected to the first threaded hole 10 on the filter bucket 4 by means of bolts passing through the mounting hole 3 and threaded connection, so as to achieve a stable installation with the mounting base 1. Disassembly and replacement are also very convenient, and maintenance and cleaning are easy.

[0018] A rectangular groove 11 is provided at the bottom of the outer wall of the filter disc 6. The rectangular groove 11 is slidably engaged with the fixing block 5. This design allows the filter disc 6 to move flexibly within the storage groove 2, making it convenient to remove and clean the filtered debris. The filter disc 6 is located below the filter hopper 4, forming a graded filtration system with the filter hopper 4, which significantly improves the filtration effect of the fixture and the quality of cutting fluid recovery.

[0019] The clamping assembly 9 includes a mounting groove 12 and a rectangular slide 13 formed at the bottom of the mounting base 1. A servo motor 14 is fixedly installed on the bottom of the inner wall of the mounting groove 12. A bevel gear 15 is fixedly connected to the output end of the servo motor 14. The bevel gear 15 meshes with a bevel gear 17. A threaded rod 16 is rotatably connected in the rectangular slide 13. The threaded rod 16 is tightly designed so that when the servo motor 14 drives it to rotate, the moving rods 18 distributed around the mounting base 1 can move synchronously. One end of the threaded rod 16 located in the mounting groove 12 is fixedly connected to the bevel gear 17. The clamping assembly 9 drives the bevel gear 15 to rotate through the servo motor 14, which in turn drives the threaded rod 16 with the bevel gear 17 to rotate. Finally, driven by the threaded rod 16, the moving rods 18 synchronously approach and clamp the motor cover.

[0020] A rectangular sliding rod 18 is slidably connected within the rectangular groove 13. A second threaded hole 19 is provided at one end of the bottom of the sliding rod 18, and a spring resistance trigger clamp 20 is fixedly installed at one end of the top of the sliding rod 18. The spring resistance trigger clamp 20 is an existing technology used in this field. After the clamp contacts the motor cover, the spring resistance is squeezed. When the contact rod contacts the first control switch, the second motor automatically stops working, which improves the automation level of the device. At the same time, it can clamp motor covers of different sizes and ensure that the clamping force is the same, so it will not be described in detail.

[0021] A rectangular frame 21 is fixedly connected to the top of the mounting base 1. The rectangular frame 21 serves to stabilize the moving rod 18, allowing the moving rod 18 to move stably without deviation. The rectangular frame 21 slides with the outer wall of the moving rod 18. The threaded rod 16 is threadedly connected to the second threaded hole 19. The moving rod 18 converts rotational motion into linear motion through the rotation of the threaded rod 16 and the second threaded hole 19, thereby driving the moving rod 18 to perform linear reciprocating motion.

[0022] It should be noted that the servo motor 14 is a Panasonic MINASA6 series servo motor. The specific specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here. All of them can be powered by external devices and controlled to turn on and off.

[0023] Working principle: First, place the motor cover on top of the mounting base 1, start the servo motor 14, which drives the first bevel gear 15 to rotate, thereby driving the second bevel gear 17 and the threaded rod 16 to rotate. The threaded rod 16 engages with the second threaded hole 19 at the bottom of the moving rod 18, converting the rotational motion into linear motion, causing the moving rod 18 to move synchronously towards the center and clamp the edge of the motor cover. After the spring resistance trigger clamping plate 20 contacts the motor cover, the spring resistance is squeezed. When the contact rod triggers the control switch, the servo motor 14 automatically stops, completing the clamping. During the clamping process, the rectangular frame 21 ensures the stable movement of the moving rod 18 and avoids deviation.

[0024] During machining, cutting fluid and chips fall into filter hopper 4. Larger chips are initially filtered, while liquid and smaller chips enter filter disc 6 for secondary filtration. The filtered cutting fluid flows along the inclined surface of the circular groove 7 to the drain port 8 for centralized recycling. For cleaning, filter hopper 4 can be disassembled and filter disc 6 can be slid out to remove chips. This fixture, through its staged filtration and automatic clamping design, improves machining efficiency, reduces environmental pollution, and adapts to the machining needs of motor covers of different sizes.

[0025] 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.
