Description

Technical Field

[0001] This utility model relates to the field of radial milling machine worktable processing equipment, and in particular to a quick clamping mechanism for radial milling machine worktable. Background Technology

[0002] A radial milling machine is a machine tool widely used in the field of machining. It can be used to perform milling, drilling, boring and other machining operations on various metal and non-metal materials. In the machining process, radial milling machines are widely used for milling planes, grooves, and shaped surfaces. During the operation of a radial milling machine, the worktable is used to fix and support the workpiece to be machined. Traditional worktables often use T-slots with bolts and pressure plates to clamp the workpiece at a single point or in stages. This is cumbersome, time-consuming and difficult to guarantee the uniformity of the clamping force at multiple points and the center alignment accuracy of the workpiece.

[0003] Currently, there are various clamping methods for the worktable of radial milling machines on the market, but some traditional clamping mechanisms have some shortcomings. For example, some clamping mechanisms use manual single clamping, requiring operators to operate each clamping point sequentially. This is not only time-consuming, but also makes it difficult to ensure that the clamping force at each clamping point is uniform. This can easily lead to workpiece displacement or deformation during processing due to uneven force, affecting machining accuracy. In addition, some clamping mechanisms use cylinders to drive clamping blocks to clamp the workpiece. However, cylinder driving requires an air source, increasing the complexity and cost of the equipment. Furthermore, it cannot be used in some locations without an air source, limiting its application range. Moreover, the clamping force control of cylinder driving is relatively imprecise, and it is prone to instability due to air pressure fluctuations, affecting machining quality. Therefore, a quick clamping mechanism for the worktable of a radial milling machine is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick clamping mechanism for the worktable of a rocker milling machine, which aims to solve the problem in the prior art that "the operator needs to operate each clamping point in turn by manually clamping each individual clamping point".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick clamping mechanism for a radial milling machine table, comprising a radial milling machine and a centering assembly. The top of the radial milling machine is connected to the table via a connecting assembly. The centering assembly is disposed around the perimeter of the table and includes a clamping block, a sliding rod, and a circular plate. The middle part of the clamping block is hinged to the circumferential surface of the table. The sliding rod is slidably connected to the inner wall of the table. The circular plate is disposed inside the table. An arc-shaped block is fixedly connected to the circumferential surface of the circular plate. One end of the sliding rod contacts the bottom of the clamping block near the table, and the other end of the sliding rod contacts the surface of the arc-shaped block.

[0006] As a further description of the above technical solution: The connecting assembly includes a fixed base, which is fixedly connected to the top of the radial milling machine, and the top of the fixed base is fixedly connected to the bottom of the worktable.

[0007] As a further description of the above technical solution: The bottom of the workbench is detachably connected to the top of the fixed base by fixing bolts, and the top of the fixed base is provided with threaded holes for the fixing bolts to be installed.

[0008] As a further description of the above technical solution: The top of the clamping block is provided with a protrusion, and the clamping block is configured as a J-shape.

[0009] As a further description of the above technical solution: The number of sliding rods and the number of arc blocks are both set to multiple groups, and the number of each group is equal.

[0010] As a further description of the above technical solution: The centering assembly also includes a bearing seat and a worm gear. The bearing seat is fixedly connected to the top of the fixed base, and the worm gear passes through and is rotatably connected to the inner wall of the bearing seat. A handwheel is fixedly connected to the right side of the worm gear.

[0011] As a further description of the above technical solution: The centering assembly also includes a rotating rod, which is rotatably connected to the top of the fixed base and coaxially arranged with the fixed base. The top of the rotating rod is fixedly connected to the bottom of the circular plate and coaxially arranged with the circular plate.

[0012] As a further description of the above technical solution: The centering assembly also includes a worm gear, which is fixedly connected to the outer wall of the rotating rod, and the front side of the worm gear meshes with the rear side of the worm.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting multiple sets of sliding rods and arc blocks in equal quantities, the circular plate rotates, causing the arc blocks to rotate synchronously. The curved surface of the arc blocks pushes the sliding rods to slide, thereby driving multiple clamping blocks to move synchronously, realizing rapid synchronous clamping of the workpiece. This avoids the manual single clamping method, thereby shortening the clamping time and improving the processing efficiency. At the same time, it ensures that the clamping force at each clamping point is uniform and consistent, effectively avoiding displacement or deformation of the workpiece due to uneven force, and improving the processing accuracy.

[0014] 2. In this utility model, by adopting worm gear transmission, it has a self-locking characteristic. After clamping, no additional locking device is needed to prevent loosening, ensuring safety and stability during the processing. Moreover, all transmission components are integrated inside the worktable, with only the handwheel exposed. The structure is compact, avoids external collisions, extends service life, and is easy to maintain. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a quick clamping mechanism for a worktable of a rocker milling machine, comprising a rocker milling machine 1 and a centering assembly 10. The top of the rocker milling machine 1 is connected to the worktable 2 via a connecting assembly 11, and the centering assembly 10 is disposed around the perimeter of the worktable 2.

[0019] Reference Figure 2 - Figure 4The centering assembly 10 includes a clamping block 101, a sliding rod 103, and a circular plate 104. The middle part of the clamping block 101 is hinged to the circumferential surface of the worktable 2. A protrusion 102 is provided on the top of the clamping block 101. The upper protrusion 102 of the clamping block 101 is used to press the outer edge of the workpiece and can adapt to the contour of workpieces of different sizes. The clamping block 101 is J-shaped. The sliding rod 103 is slidably connected to the inner wall of the worktable 2. The circular plate 104 is located inside the worktable 2.

[0020] Reference Figure 3 and Figure 4 An arc-shaped block 105 is fixedly connected to the circumferential surface of the circular plate 104. When the circular plate 104 rotates, it drives multiple sets of arc-shaped blocks 105 on the circumferential surface to rotate synchronously. The curved surface of the arc-shaped block 105 pushes the slide rod 103 to slide along the inner wall of the worktable 2. The linear displacement adjustment of the slide rod 103 is achieved by using the gradual height of the arc surface. The involute curved surface of the arc-shaped block 105 determines the clamping stroke and the force amplification ratio. The number of slide rods 103 and the number of arc-shaped blocks 105 are both set to be multiple and equal. One end of the slide rod 103 contacts the bottom of the clamping block 101 near the worktable 2, and the other end of the slide rod 103 contacts the surface of the arc-shaped block 105, forming a force transmission and displacement amplification mechanism. This converts the rotational motion of the circular plate 104 into the radial movement of the clamping block 101, achieving the synchronous clamping effect of multiple clamping blocks 101.

[0021] Reference Figure 1 - Figure 3 The connecting assembly 11 includes a fixed base 111, which is fixedly connected to the top of the radial milling machine 1. The top of the fixed base 111 is fixedly connected to the bottom of the worktable 2. The bottom of the worktable 2 is detachably connected to the top of the fixed base 111 by a fixing bolt 112. The top of the fixed base 111 is provided with a threaded hole for the fixing bolt 112 to be installed, which facilitates the installation, disassembly and maintenance of the worktable 2, while ensuring the stability of the connection.

[0022] Reference Figure 1 and Figure 3 The centering assembly 10 also includes a bearing 106 and a worm gear 107. The bearing 106 is fixedly connected to the top of the fixed base 111. The worm gear 107 passes through and is rotatably connected to the inner wall of the bearing 106. A handwheel 108 is fixedly connected to the right side of the worm gear 107. The bearing 106 provides rotational support for the worm gear 107. Rotating the handwheel 108 can drive the worm gear 107 to rotate. The centering assembly 10 also includes a rotating rod 109. The rotating rod 109 is rotatably connected to the top of the fixed base 111 and is coaxial with the fixed base 111. The top of the rotating rod 109 is fixedly connected to the bottom of the circular plate 104 and is coaxial with the circular plate 104.

[0023] Reference Figure 3The centering assembly 10 also includes a worm gear 110, which is fixedly connected to the outer wall of the rotating rod 109. The front side of the worm gear 110 meshes with the rear side of the worm 107. The worm 107 can be driven by manually rotating the handwheel 108, thereby obtaining a large reduction ratio and self-locking clamping, forming a manual drive and self-locking mechanism. Through the cooperation of the worm gear 110 and the worm 107, labor-saving, precise, and self-locking clamping control is achieved, ensuring that the clamping force does not loosen during the processing.

[0024] Working principle: When in use, first align the fixed seat 111 at the bottom of the worktable 2 with the installation position at the top of the rocker milling machine 1, and use the fixing bolt 112 to pass through the bottom of the worktable 2 and screw it into the threaded hole at the top of the fixed seat 111 to achieve a fixed connection between the worktable 2 and the machine tool.

[0025] The workpiece is then placed on the workbench 2. The operator turns the handwheel 108, which drives the worm gear 107 to rotate within the bearing 106. The worm gear 107 meshes with the worm wheel 110 fixed on the outer wall of the rotating rod 109, thereby driving the rotating rod 109 to rotate around its axis. The top of the rotating rod 109 is fixedly connected to the circular plate 104, so the circular plate 104 rotates synchronously. During the rotation, the curved surfaces of the arc-shaped blocks 105 evenly distributed on the circumference of the circular plate 104 push the corresponding slide rod 103 to slide radially along the inner wall of the workbench 2. The other end of the slide rod 103 abuts against the bottom of the J-shaped clamping block 101, pushing the clamping block 101 to swing outward around its central hinge point, so that the protrusion 102 on the top of the clamping block 101 synchronously retracts towards the center of the workbench 2, thereby performing circumferential multi-point, equidistant, and synchronous centering clamping of the workpiece placed on the workbench 2.

[0026] When the handwheel 108 stops rotating, the self-locking characteristics of the worm gear 110 and worm 107 mechanism ensure that the rotating rod 109 and the circular plate 104 will not rotate in opposite directions, and the clamping force is reliably maintained to prevent loosening caused by processing vibration. When it is necessary to disassemble or replace the workpiece, the handwheel 108 is rotated in the opposite direction, the worm 107 drives the worm gear 110 to reverse, the circular plate 104 rotates in the opposite direction, the arc block 105 pulls the slide rod 103 to retract, the clamping block 101 loses the clamping force on the workpiece, so that the protrusion 102 is disengaged from the workpiece, and then the workpiece can be easily removed.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
