[0015] (III) Beneficial effects

[0016] The present invention provides a shearing device for machining machine tool parts with a safety protection structure. It has the following beneficial effects:

[0017] (1) This shearing device for machining machine tool parts with a safety protection structure, by setting up a protection component, the rubber baffle uses its flexibility and elasticity to effectively block flying debris during the shearing process, protect the operator from injury, and improve the safety of equipment use, which is very important for ensuring the personal safety of the operator, reducing casualties and corporate losses caused by accidents during the processing process. The protection component is magnetically adsorbed to the first magnetic seat and the second magnetic seat by the permanent magnet on the magnetic frame, so that fast and convenient installation and disassembly are achieved. The operator only needs to grab the handles on both sides of the magnetic frame to move it, which improves maintenance efficiency and reduces maintenance time and cost. At the same time, this design can also ensure the stability of the protection component during operation, and it can remain firmly installed even in a vibrating environment.

[0018] (ii) The shearing device for machining machine tool parts with a safety protection structure is provided with a cutting assembly. The hydraulic assembly transmits the driving force to the auxiliary cutter and the main cutter through the pressure plate, so that the main cutter can quickly cut the shaft parts under the guidance of the knife plate. At the same time, there is a height difference between the auxiliary cutter and the main cutter, and the shaft parts are cut successively, which further improves the shearing efficiency and quality. The limit columns and top springs on both sides of the main cutter use the buffering and limiting principles of the spring. During the shearing process, the limit columns limit the movement direction of the main cutter to prevent it from deflecting; the top spring provides a buffering force to prevent the main cutter from being damaged due to excessive instantaneous impact force. This not only ensures the shearing accuracy, but also extends the service life of the main cutter and reduces the cost of tool replacement.

[0019] (III) This shearing device for machining machine tool parts with a safety protection structure, by setting a limit assembly, the sliding ball on the inner wall of the top shell of the fixed frame utilizes the principle of rolling friction to make the horizontal movement of shaft parts smoother, which helps to improve the movement efficiency of shaft parts during feeding and shearing, and reduce the jamming phenomenon caused by excessive friction, thereby improving the smoothness and efficiency of the entire machining process. When the shaft parts are placed between the top shell and the bottom shell, the resistance rod drives the bottom shell to move upward to form a clamping state. During the shearing process, the top shell and the bottom shell can limit the position of the shaft parts at the same time, which can effectively prevent the shaft parts from being displaced during the shearing process, ensure the accuracy of the shearing position, and improve the machining accuracy of the product.

[0020] (IV) This shearing device for processing machine tool parts with a safety protection structure is provided with a mounting assembly, and the mounting seat and the mounting block are connected by sliding through a positioning column. The guide rail principle is used to ensure the smoothness and accuracy of the sliding of the mounting block. At the same time, the card plate and the card slot are plugged in using the mortise and tenon structure principle, and the tension is applied by the tension spring to ensure a tight fit. This design realizes the stable positioning of the mounting block in the mounting seat. During the shearing process, the mounting block can be prevented from loosening, and the installation stability of the cutting assembly and other components is ensured, thereby improving the reliability of the shearing process. The matching design of the plug block, the stop block and the limit block makes the installation and removal process of the mounting block relatively simple. The operator grabs the connecting plate to drive the plug block to insert or slide out of the mounting seat, and then rotates the stop block to complete the installation or removal operation. This not only improves the maintenance efficiency of the equipment, but also reduces the maintenance cost and reduces the downtime caused by equipment maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

This design utilizes the sliding principle of the slider 76 in the circular track, which not only allows the mounting seat 65 to have a certain degree of adjustability in the horizontal direction, but also provides support for the mounting seat 65 through the slider 76.

[0036] The limiting assembly 8 includes a fixed plate 81, the top of the fixed plate 81 is fixedly connected to a fixed frame 82, the top of the fixed frame 82 is fixedly connected to a top shell 85, the inner wall of the top shell 85 is rollingly connected to a sliding ball 86, and the sliding ball 86 is arranged in a circular array along the central axis of the top shell 85, the outer wall of the fixed frame 82 is fixedly connected to a resistance rod 83, the top of the resistance rod 83 is fixedly connected to a bottom shell 87, the inner wall of the fixed frame 82 is slidably connected to a pressing frame 84, the outer wall of the fixed plate 81 is fixedly connected to the outer wall of the mounting seat 65, the outer wall of the bottom of the fixed plate 81 is slidably connected to the top of the base 1, after the shaft components are placed between the top shell 85 and the bottom shell 87, the resistance rod 83 drives the bottom shell 87 to move upward, the bottom shell 87 is against the bottom of the shaft components, and forms a clamping state with the top shell 85 to limit the position of the shaft components.

[0037] The shearing device is mainly composed of a base 1, an adjusting component 3 and a blocking component 2, wherein the adjusting component 3 plays a core position adjustment role in the entire device, and it is coordinated by a positioning component 7, an installation component 6 and a limiting component 8.

[0038] The positioning component 7 is mainly composed of a sliding plate 71, a ring shell 74, a slider 76, a fixed shell 73 and a rotating column 75. The sliding plate 71 is slidably connected to the inner wall of the base 1. Based on the principle of sliding friction, when the position of the mounting component 6 needs to be adjusted, the operator can manually push the sliding plate 71 to make it slide along the inner wall of the base 1.

[0039] The annular shell 74 is fixed on the top of the sliding plate 71, and its inner wall is slidably connected to a plurality of sliders 76. These sliders 76 are arranged in an annular array along the central axis of the annular shell 74. This design utilizes the sliding principle of the sliders 76 in the annular track, which not only allows the mounting seat 65 to have a certain degree of adjustability in the horizontal direction, but also provides support for the mounting seat 65 through the sliders 76.

[0040] The rotating column 75 is rotatably connected to the top of the sliding plate 71 through the fixed shell 73. Following the principle of the rotating pair, the rotating column 75 can be flexibly rotated relative to the fixed shell 73. At the same time, a structure identical to the plug column 78 is provided at the diagonal of the mounting seat 65. The operator can insert the plug column 78 at the mounting seat 65 into the slot 72 to limit the rotation angle of the mounting seat 65 and then adjust the shear angle of the shaft parts. When the sliding plate 71 moves, the rotating column 75 moves accordingly. Since its top is fixedly connected to the bottom of the mounting seat 65, it drives the mounting seat 65 to adjust its position in the horizontal and vertical directions to meet the processing requirements of different shaft parts.

[0041] In addition, the slot 72 opened on the top of the sliding plate 71 and the limit seat 77, the column 78 and the compression spring 79 on the outer wall also play an important role. The bottom of the column 78 is plugged into the inner wall of the top of the base 1 through the socket. Under the action of the compression spring 79, a certain friction force is maintained between the column 78 and the base 1, realizing the position locking function, ensuring that the sliding plate 71 will not move at will after the position is adjusted.

[0042] The core components of the mounting assembly 6 include a mounting seat 65, a mounting block 61, a clamping plate 63, an insert block 610, a stop shell 612 and related connecting components. The inner wall of the mounting seat 65 is slidably connected to the mounting block 61 through a positioning column 66. By using the guide rail principle, the mounting block 61 can slide in the mounting seat 65 along the direction of the positioning column 66.

[0043] The clamping plate 63 is slidably connected to the inner walls on both sides of the mounting seat 65, and is plugged into the inner walls on both sides of the mounting block 61 through the clamping groove 62. The mounting block 61 is stably positioned in the mounting seat 65 by utilizing the mortise and tenon structure principle. The tension springs 64 connected to the corners around the clamping plate 63 always apply an inward pulling force to the clamping plate 63 based on the elastic principle of the spring, ensuring that the clamping plate 63 and the clamping groove 62 fit closely to prevent the mounting block 61 from loosening.

[0044] The plug block 610 is fixedly connected to the stopper shell 612 through the fixing column 613, and the stopper 69 rotatably connected to the inner wall of the fixing column 613 cooperates with the limit blocks 67 on the outer walls of both sides of the mounting block 61. When the mounting block 61 slides onto the mounting seat 65 along the positioning column 66, the operator grabs the connecting plate 611 and drives the two groups of plug blocks 610 to be inserted into the mounting seat 65 along the square hole on the mounting seat 65 through the connecting plate 611. The plug block 610 squeezes the card plate 63 to offset The tension of the tension spring 64 causes the tension spring 64 to accumulate elastic potential energy. After the plug block 610 slides out of the card plate 63, the tension spring 64 pulls the card plate 63 to return to its original position. When the plug block 610 squeezes the card plate 63, the card plate 63 slides in the direction of the mounting block 61 and is inserted into the card slot 62, limiting the position of the mounting block 61. Then, the stop block 69 is rotated so that the convex plate on the stop block 69 is located in the limit block 67. The position of the stop block 69 is limited by the limit block 67, thereby limiting the position of the plug block 610.

[0045] The limit assembly 8 is composed of a fixed plate 81, a fixed frame 82, a top shell 85, a sliding ball 86, a resistance rod 83, a bottom shell 87 and a pressure frame 84. The outer wall of the fixed plate 81 is fixedly connected to the outer wall of the mounting seat 65, and the bottom outer wall is slidably connected to the top of the base 1, providing an installation basis for the entire limit assembly 8. The inner wall of the top shell 85 at the top of the fixed frame 82 is rollingly connected to multiple sliding balls 86, and the principle of rolling friction is used to make the horizontal movement of shaft components smoother.

[0046] The resistance rod 83 connects the fixed frame 82 and the bottom shell 87, and the pressure frame 84 slides on the inner wall of the fixed frame 82. When the shaft parts are placed between the top shell 85 and the bottom shell 87, the resistance rod 83 drives the bottom shell 87 to move upward, and the bottom shell 87 rests on the bottom of the shaft parts, forming a clamping state with the top shell 85 to limit the position of the shaft parts. When the shaft parts are displaced during the shearing process, the top shell 85 and the bottom shell 87 can limit their position at the same time.

[0047] The blocking component 2 is located on the top of the adjusting component 3, and is mainly composed of a cutting component 4 and a protective component 5. It is responsible for the shearing and safety protection of shaft parts. The key components of the cutting component 4 include a fixed frame 48, a hydraulic component 41, a pressure plate 42, an auxiliary cutter 44, a main cutter 43 and a knife plate 45. The fixed frame 48 serves as the supporting structure of the entire cutting component 4 and provides an installation basis for other components.

[0048] The hydraulic component 41 is fixed to the inner wall at the top of the fixing frame 48. According to Pascal's principle, when the hydraulic oil is under the pressure inside the hydraulic component 41, the telescopic end of the hydraulic component 41 will produce linear motion, and the pressure plate 42 connected to the telescopic end moves downward under the drive of the hydraulic component 41. The bottom of the pressure plate 42 contacts the top of the auxiliary cutter 44, transmitting the driving force of the hydraulic component 41 to the auxiliary cutter 44.

[0049] The outer wall of the auxiliary cutter 44 is fixedly connected to the main cutter 43, and the main cutter 43 is slidably connected to the knife plate 45. Utilizing the sliding auxiliary principle, the main cutter 43 moves downward along a fixed direction under the guidance of the knife plate 45 to shear the shaft parts placed on the knife plate 45.

[0050] The limiting posts 46 slidably connected to the inner walls of both sides of the main cutter 43 and the top springs 47 fixedly connected thereto use the buffering and limiting principles of the springs. When the main cutter 43 moves downward, the limiting posts 46 limit the movement direction of the main cutter 43 to prevent it from deflecting. The top springs 47 elastically deform under the action of the shearing force to provide a buffering force to prevent the main cutter 43 from being damaged due to excessive instantaneous impact force. At the same time, they assist the main cutter 43 in resetting after the shearing is completed. Since there is a height difference between the auxiliary cutter 44 and the main cutter 43, when the main cutter 43 first shears the shaft parts, the auxiliary cutter 44 will also shear the shaft parts later.

[0051] The protective assembly 5 is composed of a rubber baffle 53, a mounting frame 51, a limit plate 56, a magnetic frame 54, a permanent magnet 55 and a first magnetic seat 52, providing safety protection for the shearing operation. The rubber baffle 53 is located at the outermost layer, and uses its flexibility and elasticity to block possible flying debris during the shearing process to protect the operator from injury. The mounting frame 51 is fixed on the top of the rubber baffle 53, and the limit plates 56 at the corners enhance the structural stability of the mounting frame 51 and provide reliable support for the rubber baffle 53.

[0052] The magnetic frame 54 is fixed to the bottom of the rubber baffle 53, and the outer walls on both sides are connected to the permanent magnets 55. The first magnetic seats 52 on the outer walls on both sides of the mounting frame 51 are magnetically adsorbed to the top of the permanent magnets 55. According to the principle of magnetic adsorption, this design enables the protective component 5 to be quickly and conveniently installed on the top of the cutting component 4, and can also be easily disassembled when maintenance or replacement is required.

[0053] In addition, the second magnetic seats 68 on the outer walls of both sides of the mounting seat 65 are magnetically attracted to the bottom of the permanent magnet 55, further enhancing the stability of the protective component 5 during operation and ensuring that it can remain firmly installed in the vibrating environment of the shearing operation. When protection is required, the operator only needs to grab the handles on both sides of the magnetic frame 54 and move downward to offset the suction force between the first magnetic seat 52 and the permanent magnet 55. After the magnetic frame 54 drives the rubber baffle 53 to move to the permanent magnet 55, the permanent magnet 55 can be magnetically attracted to the second magnetic seat 68 to stabilize the position of the rubber baffle 53.
