Description

Technical Field

[0001] This utility model relates to the field of screw head positioning fixtures for milling edge processing, and in particular to a screw head positioning fixture for milling edge processing. Background Technology

[0002] Screw head positioning fixtures for milling are auxiliary devices specifically designed for the milling process of screw heads. Their core function is to precisely fix the screw head, preventing displacement due to vibration or force during machining. They achieve centering through a positioning structure that matches the shape of the screw head (such as a groove for hexagonal or square heads), and then apply stable pressure with clamping components to ensure the head remains in position during milling. Their design must avoid the machining area, reserving working space for the milling cutter, balancing positioning accuracy and ease of operation. They are a key tool for improving the milling quality of screw head sidewalls and ensuring machining efficiency.

[0003] However, current screw head positioning fixtures for milling have the following drawbacks: First, they have limited capacity to accommodate screws of different diameters, making them unable to flexibly adapt to various diameter specifications and lacking versatility. Second, they have a narrow clamping range for screw heads of different sizes, making it difficult to accommodate diverse head sizes and limiting their applicability. In response to this technical problem, this application proposes a screw head positioning fixture for edge milling. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screw head positioning fixture for milling. The fixture aims to enable it to accept screws of different diameters, thereby improving its versatility, and to clamp screw heads of different sizes, further enhancing its versatility and applicability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A screw head positioning fixture for milling includes a base plate with a circular groove in the middle. Two clamping rings are connected inside the groove via an adjusting assembly, allowing the clamping rings to be positioned within the groove. A screw is inserted into the groove, with the bottom side of the screw's tip abutting against the top side of the clamping rings. A through groove is formed on the rear side of the base plate, with a support slidably connected inside. A first threaded rod is rotatably connected inside the through groove, with the bottom end of the support threaded onto the outer wall of the first threaded rod. A first knob is rotatably connected to the middle of the rear side of the base plate via a damping shaft, with the rear end of the first threaded rod fixedly connected inside the first knob. A positioning assembly is provided on the front side of the support to position the screw head.

[0006] Furthermore, the adjustment assembly includes a groove formed in the middle of the top side of the base plate, a round rod slidably connected inside the groove, and the end of the round rod being fixedly connected to one side of the clamping ring.

[0007] Furthermore, a plurality of limiting grooves are provided on the top side of the groove, a slider is fixedly connected to the outer wall of the round rod, and a limiting block is connected to the top of the slider through a torsion spring, the limiting block abutting against the inside of the limiting groove.

[0008] Furthermore, a latching rod is fixedly connected to one side of the limiting block, and a pull ring is fixedly connected to the other side of the limiting block. A latching groove is provided on one side of the slider, and the latching rod is engaged inside the latching groove.

[0009] Furthermore, the positioning component includes a slide groove formed on the front side of the support, a slide block is slidably connected inside the slide groove, a second threaded rod is rotatably connected inside the slide groove, and the slide block is threadedly connected to the outer wall of the second threaded rod.

[0010] Furthermore, a rotating rod is rotatably connected inside the slide groove, and the rotating rod and the slide block are connected by a connecting rod. One end of the connecting rod is rotatably connected to the front end of the rotating rod, and the other end of the connecting rod is rotatably connected to the front side of the slide block.

[0011] Furthermore, a fixing rod is fixedly connected to the bottom end of the connecting rod, and a positioning ball is fixedly connected to the bottom end of the fixing rod. A rubber sleeve is fixedly connected to the outer wall of the positioning ball, and the positioning ball is located above the circular groove.

[0012] Furthermore, a fixing plate is fixedly connected to the center of the inside of the slide groove, the bottom end of the second threaded rod is rotatably connected to the inside of the fixing plate, and a second knob is rotatably connected to the top side of the support through a damping shaft, with the top end of the second threaded rod fixedly connected to the inside of the second knob.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the sliding round rod drives the clamping ring to slide inside the round groove, thereby adjusting the distance between the two clamping rings, so that the clamping ring can support screws of different diameters, improving the versatility of the clamp. By rotating the limiting block, it is made to abut against the inside of the limiting groove, and at the same time, the buckling rod is engaged with the inside of the buckling groove, further improving the clamping force of the limiting block against the limiting groove.

[0014] 2. In this utility model, rotating the second knob causes the second threaded rod to rotate, which in turn drives the slide to slide up and down. This causes the slide to move the top of the connecting rod up and down. During the up-and-down movement of the connecting rod, the bottom of the connecting rod will drive the rotating rod to rotate, thereby adjusting the height of the bottom of the connecting rod and thus adjusting the height of the positioning ball. This keeps the positioning ball horizontal, and the screw head is clamped by the positioning ball and the clamping ring. This allows the clamp to clamp screw heads of different sizes, further improving the versatility and applicability of the clamp. 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 1-3This utility model provides an embodiment of a screw head positioning fixture for milling, comprising a base plate 1, a circular groove in the middle of the base plate 1, a screw 2 inserted into the groove, the bottom side of the top of the screw 2 abutting the top side of a clamping ring 13, the clamping ring 13 supporting the screw 2, a through groove in the rear side of the base plate 1, a support 6 slidably connected inside the through groove, a first threaded rod 3 rotatably connected inside the through groove, the bottom end of the support 6 threadedly connected to the outer wall of the first threaded rod 3, a first knob 14 rotatably connected to the middle of the rear side of the base plate 1 via a damping shaft, the rear end of the first threaded rod 3 fixedly connected inside the first knob 14, rotating the first knob 14 causes the first threaded rod 3 to rotate, causing the first threaded rod 3 to drive the support 6 to slide, thereby adjusting the position of the support 6 so that the positioning ball 12 can be held directly above the screw 2. (See reference...) Figure 4 and Figure 5 A groove is formed in the center of the top side of the base plate 1. A round rod 16 is slidably connected inside the groove. The end of the round rod 16 is fixedly connected to one side of the clamping ring 13. Multiple limiting grooves are formed on the top side of the groove. A slider 17 is fixedly connected to the outer wall of the round rod 16. The top of the slider 17 is connected to a limiting block 18 through a torsion spring. The limiting block 18 abuts against the inside of the limiting groove. A latching rod 19 is fixedly connected to one side of the limiting block 18. A pull ring 20 is fixedly connected to the other side of the limiting block 18. A latching groove is formed on one side of the slider 17. The latching rod 19 is engaged inside the latching groove. The sliding rod 16 drives the clamping ring 13 to slide inside the circular groove, thereby adjusting the distance between the two clamping rings 13. This allows the clamping ring 13 to accept screws 2 of different diameters, improving the versatility of the fixture. By rotating the limiting block 18, it is brought into contact with the inside of the limiting groove, and the latching rod 19 is engaged with the inside of the latching groove, further increasing the clamping force of the limiting block 18 against the limiting groove. The pulling ring 20 pulls the limiting block 18 to rotate. The torsion spring is of a type with large elastic potential energy to prevent the limiting block 18 from rotating accidentally.

[0019] Reference Figure 1 , Figure 2 and Figure 6The support 6 has a sliding groove on its front side. A slide block 9 is slidably connected inside the groove. A second threaded rod 7 is rotatably connected inside the groove. The slide block 9 is threaded onto the outer wall of the second threaded rod 7. A rotating rod 5 is rotatably connected inside the groove. The rotating rod 5 and the slide block 9 are connected by a connecting rod 11. One end of the connecting rod 11 is rotatably connected to the front end of the rotating rod 5, and the other end is rotatably connected to the front side of the slide block 9. A fixing rod 4 is fixedly connected to the bottom end of the connecting rod 11. A positioning ball 12 is fixedly connected to the bottom end of the fixing rod 4. A rubber sleeve 15 is fixedly connected to the outer wall of the positioning ball 12. The positioning ball 12 is located above the circular groove. A fixing plate 10 is fixedly connected to the middle of the groove. The bottom end of the second threaded rod 7 is rotatably connected to the inside of the fixing plate 10. A second knob 8 is rotatably connected to the top side of the support 6 via a damping shaft. The top end of the second threaded rod 7 is fixedly connected to the inside of the second knob 8. Rotating the second knob 8... The second threaded rod 7 rotates, causing the slide block 9 to slide up and down. This causes the slide block 9 to move the top of the connecting rod 11 up and down. During the up-and-down movement of the connecting rod 11, the bottom of the connecting rod 11 will drive the rotating rod 5 to rotate, thereby adjusting the height of the bottom of the connecting rod 11 and thus adjusting the height of the positioning ball 12, keeping the positioning ball 12 horizontal. The positioning ball 12 and the clamping ring 13 are used to clamp the head of the screw 2. The rubber sleeve 15 is used to prevent the positioning ball 12 and the screw 2 from directly contacting each other, which could damage the head of the screw 2, and to increase the friction of the clamping, thereby improving the stability of the clamping. At the same time, the device can clamp screw heads of different sizes, further improving the versatility and applicability of the fixture. The damping shaft is of a type with high damping to prevent vibrations generated during use from causing the first threaded rod 3 and the second threaded rod 7 to rotate unexpectedly.

[0020] Working principle: First, insert screw 2 into the circular groove. Then, slide the circular rod 16 to drive the clamping ring 13 to slide inside the circular groove, thereby adjusting the distance between the two clamping rings 13. This allows the clamping rings 13 to move to the bottom side of screw 2 simultaneously, thus receiving the head of screw 2. Next, rotate the limiting block 18 to make it abut against the inside of the limiting groove, and at the same time, make the latching rod 19 engage inside the latching groove. Then, rotate the second knob 8 to make the second threaded rod 7 rotate, causing the second threaded rod 7 to drive the slide block 9 to slide up and down, causing the slide block 9 to drive the top of the connecting rod 11 to move up and down. During the up-and-down movement of the connecting rod 11, the bottom end of the connecting rod 11 will drive the rotating rod 5 to rotate, thereby adjusting the height of the bottom end of the connecting rod 11, and thus adjusting the height of the positioning ball 12, keeping the positioning ball 12 horizontal. The positioning ball 12 and the clamping ring 13 will clamp the head of the screw 2. At the same time, the first threaded rod 3 can be rotated by rotating the first knob 14, causing the first threaded rod 3 to drive the support 6 to slide, thereby adjusting the position of the support 6 so that the positioning ball 12 can be kept directly above the screw 2. Then the head of the screw 2 can be processed.

[0021] 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.
