Description

Technical Field

[0001] The invention relates to the technical field of bolt processing, in particular to a sawing machine for processing stud bolts. Background Art

[0002] A stud bolt is a fastener with threads on both ends and a bare rod or partially threaded structure in the middle. It was originally designed to solve the problem of limited installation of single-sided bolts in complex assembly scenarios. This component can be traced back to the Industrial Revolution in the 19th century. With the complexity of mechanical equipment, engineers found that traditional single-headed bolts could not meet the needs in closed spaces or structures that require bidirectional force, so stud bolts came into being. Its core function is to connect with different components through threads on both ends, which can achieve high-precision positioning and withstand axial tension and shear force. It is particularly suitable for scenarios such as pipe flanges, engine blocks, bridge supports, etc. that require frequent disassembly and maintenance.

[0003] The patent application with application number CN201821001350.X discloses a sawing machine for processing stud bolts, including a device body, a workbench, a connecting rod and a fixing rod. A first hydraulic cylinder is arranged above the inner lower end surface of the device body, and a support platform is installed above the first hydraulic cylinder. At the same time, a support rod is connected between the first hydraulic cylinder and the support platform. The workbench is installed above the support platform, and a through hole is opened on the surface of the workbench. A second hydraulic cylinder is arranged on the inner side of the workbench, and a telescopic rod is connected to the outer side of the second hydraulic cylinder, and an extrusion plate is fixed to the outer side of the telescopic rod.

[0004] In summary, when the stud bolts are processed simultaneously, if they are not completely fixed and the forces on both sides are inconsistent, the side with greater force will be pressed down, while the side with less force will rise, causing the stud bolt to tilt, thereby reducing the accuracy of the stud bolt processing.

[0005] For this purpose, we propose a sawing machine for stud bolt processing. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a sawing machine for processing stud bolts to solve the problems raised in the above background technology.

One end of the second connecting rod away from the second fixed frame is rotatably connected to a second sliding block through a rotating shaft. The second sliding block is slidably connected to the inner wall of the sliding groove. The second connecting rod slides in the sliding groove through the second sliding block, restricting the movement range of the second fixed frame and improving its stability.

[0008] According to the above technical solution, the clamping assembly includes a connecting block fixedly connected to the second hydraulic rod. A stress plate is fixedly connected to the outer surface of the top of the connecting block. An auxiliary rod is rotatably connected to the inner wall of the connecting block through a rotating shaft. One end of the auxiliary rod away from the connecting block is rotatably connected to a rotating frame through a rotating shaft. The connecting block drives the rotating frame to rotate around a fixed point through the auxiliary rod, causing the rotating frame to flip towards the stress plate.

[0009] According to the above technical solution, one end of the rotating frame away from the connecting block is rotatably connected to a third sliding block through a rotating shaft. One end of the third sliding block away from the rotating frame is movably sleeved on the outer surface of the second fixed shaft. The second fixed shaft is used to limit the sliding distance and sliding direction of the third sliding block.

[0010] According to the above technical solution, one end of the outer wall of the rotating frame away from the third sliding block is rotatably connected to a clamping plate through a rotating shaft. A second spring is fixedly connected to the outer surface of one end of the clamping plate close to the rotating frame. One end of the second spring away from the clamping plate is fixedly connected to the rotating frame. Through the elastic action of the second spring, the clamping plate adjusts its angle during the clamping process.

[0011] According to the above technical solution, the processing mechanism includes a first fixed frame fixedly connected to the first telescopic rod. A second telescopic rod is fixedly connected to the inner wall of the first fixed frame. The output end of the second telescopic rod is fixedly connected to a fixed block. A second motor is fixedly connected to the outer surface of the fixed block. The output end of the second motor penetrates through the fixed block and is fixedly connected to a saw blade. The second telescopic rod adjusts the distance between the saw blade and the double-headed bolt through telescopic movement.

[0012] According to the above technical solution, a first rotating rod is rotatably connected to the inner wall of the first fixed frame through a rotating shaft. One end of the first rotating rod away from the first fixed frame is rotatably connected to a second rotating rod through a rotating shaft. One end of the second rotating rod away from the first rotating rod is fixedly connected to the fixed block. The first rotating rod and the second rotating rod are used to limit the movement range of the fixed block and improve its stability.

[0013] According to the above technical solution, the inner wall of the top of the first fixing frame is rotatably connected with a first connecting rod through a rotating shaft. One end of the first connecting rod away from the first fixing frame is rotatably connected with a first sliding block through a rotating shaft. The first sliding block is movably sleeved on the outer surface of the first fixing shaft. The first sliding block keeps the sliding distance of the first fixing frame the same through the first connecting rod.

[0014] According to the above technical solution, the top of the first sliding block is fixedly connected with a first spring. One end of the first spring away from the first sliding block is fixedly connected with the first fixing shaft. Through the elastic action of the first spring, the first sliding block is assisted to reset to the initial position after moving.

[0015] Compared with the prior art, the present invention provides a sawing machine for processing double-headed bolts, which has the following beneficial effects: 1. By setting a sawing machine for processing double-headed bolts, when it is necessary to simultaneously process both ends of double-headed bolts with different lengths, the clamping assembly clamps and fixes the double-headed bolts to improve the stability during the processing. The first motor adjusts the position of the sliding frame through the rotating shaft to position the double-headed bolts with the saw blade, so as to improve the processing accuracy of the double-headed bolts.

[0016] 2. By setting a processing mechanism, when it is necessary to simultaneously process both ends of double-headed bolts with different lengths, the first telescopic rod pushes the first fixing frame to move towards both ends of the double-headed bolts, the second telescopic rod pushes the fixing block to move towards one end of the double-headed bolts, and the second motor processes the double-headed bolts through the saw blade, thereby realizing the processing operation of double-headed bolts with different lengths.

[0017] 3. By setting an adjusting mechanism, when it is necessary to simultaneously process both ends of double-headed bolts with different lengths, the second hydraulic rod supports both ends of the double-headed bolts through the force-bearing plate on the top of the connecting block. The first hydraulic rod pulls the second fixing frame to move towards one side of the sliding frame. When the second fixing block moves towards the sliding frame under the action of the first hydraulic rod, the second connecting rod pushes the second sliding block to slide on the inner wall of the sliding groove. The second connecting rod restricts the moving range of the second fixing frame through the sliding of the second sliding block, and improves the stability of the double-headed bolts during the moving process.

[0018] 4. By setting a clamping assembly, when the first hydraulic rod pushes the second fixing frame to move towards one side of the sliding frame, during the process of the connecting block approaching the sliding frame, the auxiliary rod pulls the rotating frame to move towards one side of the double-headed bolts. Under the action of the auxiliary rod, the rotating frame makes the clamping plate move towards one side of the force-bearing plate. When the force-bearing plate contacts the outer surface of the double-headed bolts, the second spring adjusts the angle of the clamping plate through the elastic action, increasing the contact area between the clamping plate and the double-headed bolts, thereby improving the clamping stability of the force-bearing plate and the clamping plate for bolts with different diameters.

When it is necessary to simultaneously process both ends of double-headed bolts of different lengths, the clamping assembly 709 clamps and fixes the double-headed bolts, the first motor 2 adjusts the position of the sliding frame 701 through the rotating shaft 3 to accurately position the double-headed bolts with the saw blade 607, the first telescopic rod 4 adjusts the distance between the processing mechanisms 6, and the saw blade 607 processes the double-headed bolts.

The inner wall of the first fixing frame 601 is fixedly connected to a second telescopic rod 602. The output end of the second telescopic rod 602 is fixedly connected to a fixing block 603. The outer surface of the fixing block 603 is fixedly connected to a second motor 606. The output end of the second motor 606 penetrates through the fixing block 603 and is fixedly connected to a saw blade 607. The second telescopic rod 602 adjusts the distance between the saw blade 607 and the double-headed bolt through telescopic movement. When it is necessary to simultaneously process both ends of double-headed bolts of different lengths, the first telescopic rod 4 pushes the first fixing frame 601 towards both ends of the double-headed bolt. The second telescopic rod 602 pushes the fixing block 603 towards one end of the double-headed bolt. The second motor 606 processes the double-headed bolt through the saw blade 607.

The top of the first sliding block 609 is fixedly connected to a first spring 610. One end of the first spring 610 away from the first sliding block 609 is fixedly connected to the first fixing shaft 5. The first spring 610 assists the first sliding block 609 to return to the initial position after moving through elastic action. When the first telescopic rod 4 pushes the first fixing frame 601 towards the processing side of the double-headed bolt, the first fixing frame 601 pulls the first sliding block 609 to move along the outer surface of the first fixing shaft 5 through the first connecting rod 608 and stretches the first spring 610.

[0028] Embodiment 2: Please refer to Figures 5 - 8, on the basis of Embodiment 1, the present invention provides a technical solution: The clamping assembly 709 includes a connection block 7091 fixedly connected to the second hydraulic rod 706. The outer surface of the top of the connection block 7091 is fixedly connected with a force-bearing plate 7092. The inner wall of the connection block 7091 is rotatably connected with an auxiliary rod 7093 through a rotating shaft. One end of the auxiliary rod 7093 away from the connection block 7091 is rotatably connected with a rotating frame 7094 through a rotating shaft. The connection block 7091 drives the rotating frame 7094 to rotate around a fixed point through the auxiliary rod 7093, so that the rotating frame 7094 flips towards the force-bearing plate 7092. One end of the rotating frame 7094 away from the connection block 7091 is rotatably connected with a third sliding block 7095 through a rotating shaft. One end of the third sliding block 7095 away from the rotating frame 7094 is movably sleeved on the outer surface of the second fixed shaft 703. The second fixed shaft 703 is used to limit the sliding distance and sliding direction of the third sliding block 7095. When it is necessary to simultaneously process both ends of double-headed bolts with different lengths, the second hydraulic rod 706 supports both ends of the double-headed bolt through the force-bearing plate 7092 on the top of the connection block 7091. The first hydraulic rod 704 pulls the second fixed frame 705 to move towards the sliding frame 701. When the second fixed block 603 moves towards the sliding frame 701 under the action of the first hydraulic rod 704, it pushes the second sliding block 708 to slide on the inner wall of the sliding groove 702 through the second connecting rod 707. The second connecting rod 707 restricts the moving range of the second fixed frame 705 through the sliding of the second sliding block 708, improving the stability of the movement of the second fixed frame 705.

[0029] One end of the outer wall of the rotating frame 7094 away from the third sliding block 7095 is rotatably connected with a clamping plate 7096 through a rotating shaft. The outer surface of one end of the clamping plate 7096 close to the rotating frame 7094 is fixedly connected with a second spring 7097. One end of the second spring 7097 away from the clamping plate 7096 is fixedly connected with the rotating frame 7094. When the first hydraulic rod 704 pushes the second fixed frame 705 to move towards the sliding frame 701, the connection block 7091 approaches the sliding frame 701 and pulls the rotating frame 7094 to move towards the double-headed bolt through the auxiliary rod 7093. Under the action of the auxiliary rod 7093, the rotating frame 7094 moves the clamping plate 7096 towards the force-bearing plate 7092. When the force-bearing plate 7092 contacts the outer surface of the double-headed bolt, the second spring 7097 adjusts the angle of the clamping plate 7096 through elastic action, increasing the contact area between the clamping plate 7096 and the double-headed bolt, thereby improving the clamping stability of the force-bearing plate 7092 and the clamping plate 7096 on bolts with different diameters.
