Description

Technical Field

[0001] This utility model relates to the field of milling equipment technology, and more specifically, to a milling device for fastener processing. Background Technology

[0002] Fasteners are commonly used components in industrial production. They are a type of mechanical part used for fastening connections and have extremely wide applications. Fasteners are used in a wide range of industries and are among the most widely used basic mechanical components. Currently, the manufacturing process of fasteners requires milling, thus requiring the use of milling equipment.

[0003] For example, patent publication number CN220295948U discloses a milling device for high-performance anchor fasteners, relating to the field of high-performance anchor fastener milling. It includes: a base, a retaining shell fixedly connected to the top of the base, a cutting body disposed above the retaining shell, a worktable disposed on the top of the base, an upper clamping plate disposed above the worktable, a motor fixedly connected to the right side of the base, a slide fixedly connected to the bottom of the inner wall of the base, and a lower clamping plate disposed below the upper clamping plate. This utility model uses an arc-shaped plate; rotating a rotating ring causes the upper plate to move downwards via a connecting block. When the arc-shaped plate contacts the anchor fastener, a spring is compressed, ensuring that the outer surface of the anchor fastener is not damaged. Simultaneously, the elasticity of the spring ensures a more secure clamping of the anchor fastener. Because the lower and upper clamping plates have multiple openings, multiple anchor fasteners can be clamped for processing, improving work efficiency.

[0004] In the aforementioned patent, the inventor believes that when milling fasteners, the alignment accuracy of multiple fasteners during clamping is not high, and the end positions of multiple fasteners are prone to being uneven. In addition, the fixing and unclamping of fasteners require manual control, which is quite troublesome. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the technical problems of fasteners being easily uneven and difficult to fix during milling and clamping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milling device for fastener processing, comprising a worktable and a milling equipment body disposed on the worktable, wherein a pair of clamping assemblies for clamping fasteners are disposed on the worktable, the clamping assemblies comprising a lower clamping plate, the lower clamping plate being bolted to the upper surface of the worktable, an upper clamping plate being disposed above the lower clamping plate, and a plurality of clamping annular grooves for limiting fasteners being disposed on the opposite surfaces of the upper clamping plate and the lower clamping plate, and an elastic connecting assembly being disposed on the lower clamping plate and the upper clamping plate;

[0007] A drive unit is provided on the workbench, and a pair of movable plates are provided on the drive unit. Each movable plate has a calibration plate on one side that is movably connected to a fastener. The movable plate and the calibration plate are provided with an elastic connection component two. An active pressure plate is fixedly connected to the top of each movable plate. The active pressure plate is used to press down the upper clamping plate.

[0008] In a preferred embodiment, a rubber ring gasket is fixedly connected inside the clamping ring groove.

[0009] In a preferred embodiment, a connecting rod is fixedly connected to a pair of upper mounting plates.

[0010] In a preferred embodiment, the elastic connection assembly includes a T-shaped guide rod, which is fixedly connected to the top of the lower clamping plate and slidably connected to the upper clamping plate. A compression spring is sleeved on the T-shaped guide rod, and the compression spring is located between the lower clamping plate and the upper clamping plate.

[0011] In a preferred embodiment, the drive unit includes a module box, which is bolted to the upper surface of the worktable. A bidirectional lead screw is rotatably connected inside the module box, and a pair of transmission seats are threaded onto the bidirectional lead screw. The transmission seats are slidably connected inside the module box. A servo motor for driving the bidirectional lead screw to rotate is fixedly connected to one end of the module box, and the moving plate is fixedly connected to the transmission seats.

[0012] In a preferred embodiment, the worktable is provided with a guide slide assembly, which includes a pair of fixed blocks. The fixed blocks are bolted to the upper surface of the worktable, and a light rod is fixedly connected to the pair of fixed blocks. A pair of movable plates are slidably connected to the light rod.

[0013] In a preferred embodiment, the second elastic connection component includes a telescopic rod, the two ends of which are fixedly connected to the opposite surfaces of the movable plate and the calibration plate, respectively, and a second compression spring is sleeved on the telescopic rod.

[0014] In a preferred embodiment, the active pressure plate is inclined, and a passive pressure block is fixedly connected to one side of the upper clamping plate. One end of the passive pressure block is arc-shaped, and the active pressure plate is movably connected to the passive pressure block.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This milling device for fastener processing utilizes a pair of relatively movable moving plates. By placing the pair of moving plates at both ends of the fastener on the clamping assembly, the movement of the pair of moving plates towards each other can push and align the ends of the fastener through a calibration plate elastically connected to them. This ensures the alignment accuracy of multiple fasteners. At the same time, the active pressure plate on the moving plates can obliquely press the passive pressure plate to promote the downward movement of the upper clamping plate. In this way, the upper and lower clamping plates can easily clamp and fix multiple fasteners, thus eliminating the need for manual fastener fixing, which is more convenient.

[0022] 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.

[0023] See also Figures 1-4 This utility model provides a milling device for fastener processing, including a worktable 1 and a milling equipment body 2 disposed on the worktable 1. The milling equipment body 2 adopts a gantry milling machine, which can perform three-axis three-dimensional milling processing on fasteners.

[0024] In this embodiment: A pair of clamping components for clamping fasteners are provided on the workbench 1. The clamping components include a lower clamping plate 3, which is bolted to the upper surface of the workbench 1. An upper clamping plate 4 is provided above the lower clamping plate 3. Several clamping ring grooves 5 for limiting the fasteners are provided on the opposite surfaces of the upper clamping plate 4 and the lower clamping plate 3.

[0025] By placing the fastener in the clamping ring groove 5 on the lower clamping plate 3 and controlling the upper clamping plate 4 to move toward the fastener, the lower clamping plate 3 and the upper clamping plate 4 can clamp the fastener. The advantage of setting a pair of clamping components is that it can provide two fixed fulcrums for the fastener, resulting in high stability.

[0026] In this embodiment, a rubber ring pad 12 is fixedly connected inside the clamping ring groove 5.

[0027] The rubber ring gasket 12 is designed to prevent the lower clamping plate 3 and the upper clamping plate 4 from causing damage to the fasteners due to clamping.

[0028] In this embodiment: a connecting rod 14 is fixedly connected to a pair of upper mounting plates 4.

[0029] The connecting rod 14 can connect and fix a pair of upper clamping plates 4, thus ensuring the stability of the pair of upper clamping plates 4 when subjected to pressure drop.

[0030] In this embodiment: an elastic connecting component 6 is provided on the lower clamping plate 3 and the upper clamping plate 4. The elastic connecting component 6 includes a T-shaped guide rod 61, which is fixedly connected to the top of the lower clamping plate 3 and slidably connected to the upper clamping plate 4. A compression spring 62 is sleeved on the T-shaped guide rod 61, and the compression spring 62 is located between the lower clamping plate 3 and the upper clamping plate 4.

[0031] When the upper clamping plate 4 moves towards the lower clamping plate 3, the upper clamping plate 4 can slide on the T-shaped guide rod 61, and the compression spring 62 is compressed. When the pressure on the upper clamping plate 4 is released, the elastic reset of the compression spring 62 can facilitate the opening of the upper clamping plate 4, so as to allow for the removal and placement of fasteners and subsequent material loading.

[0032] In this embodiment: a drive unit is provided on the workbench 1. The drive unit includes a module box 7. The module box 7 is bolted to the upper surface of the workbench 1. A bidirectional lead screw 71 is rotatably connected inside the module box 7. A pair of transmission seats 72 are threadedly connected to the bidirectional lead screw 71. The transmission seats 72 are slidably connected inside the module box 7. A servo motor 73 for driving the bidirectional lead screw 71 to rotate is fixedly connected to one end of the module box 7.

[0033] By activating the servo motor 73, the bidirectional lead screw 71 can rotate inside the module box 7. Then, a pair of transmission seats 72 sliding inside the module box 7 can move closer to or further away from each other in a linear motion under the threaded connection of the bidirectional lead screw 71.

[0034] In this embodiment: a pair of movable plates 8 are provided on the drive unit, and the movable plates 8 are fixedly connected to the conduction seat 72.

[0035] A pair of movable plates 8 are set on corresponding conductive seats 72 and can move closer to or further away from each other.

[0036] In this embodiment: the workbench 1 is provided with a guide slide assembly, which includes a pair of fixed blocks 15. The fixed blocks 15 are connected to the upper surface of the workbench 1 by bolts. A light rod 151 is fixedly connected to the pair of fixed blocks 15, and a pair of movable plates 8 are slidably connected to the light rod 151.

[0037] The arrangement of sliding the end of the movable plate 8 away from the conduction seat 72 on the light rod 151 can improve the stability of the movement of the movable plate 8.

[0038] In this embodiment, each movable plate 8 has a calibration plate 9 on one side that is movably connected to a fastener.

[0039] When a pair of movable plates 8 are located at both ends of the fastener and move closer to each other, the movable plates 8 can drive the corresponding calibration plates 9 to move towards the ends of the fastener. By pushing the ends of the fastener with a pair of calibration plates 9, the alignment of the ends of multiple fasteners set on the lower clamping plate 3 can be ensured.

[0040] In this embodiment: the movable plate 8 and the calibration plate 9 are provided with an elastic connection component 2 10. The elastic connection component 2 10 includes a telescopic rod 101. The two ends of the telescopic rod 101 are respectively fixedly connected to the opposite surfaces of the movable plate 8 and the calibration plate 9. A compression spring 2 102 is sleeved on the telescopic rod 101.

[0041] With the elastic extension and retraction of the telescopic rod 101 and the compression spring 102, after the pair of calibration plates 9 are synchronously aligned at both ends of the fastener, the contraction of the telescopic rod 101 and the compression of the compression spring 102 can provide the moving plate 8 with a further moving distance, which can facilitate the moving plate 8 to provide clamping pressure for the upper clamping plate 4.

[0042] In this embodiment: an active pressure plate 11 is fixedly connected to the top of each movable plate 8. The active pressure plate 11 is used to press down the upper clamping plate 4. The active pressure plate 11 is inclined. A passive pressure block 13 is fixedly connected to one side of the upper clamping plate 4. One end of the passive pressure block 13 is arc-shaped. The active pressure plate 11 and the passive pressure block 13 are movably connected.

[0043] After a pair of calibration plates 9 are synchronously aligned at both ends of the fastener, the moving plate 8, which continues to move, can drive the active pressure plate 11 on it to press against the passive pressure block 13. By using the tilt angle of the active pressure plate 11 and the arc at the end of the passive pressure block 13, the passive pressure block 13 can slide and move downward on the inner side of the active pressure plate 11. With the T-shaped guide rod 61 providing vertical guidance for the upper clamping plate 4, the upper clamping plate 4 can move towards the fastener on the lower clamping plate 3 and clamp.
