Description

Technical Field

[0001] This utility model belongs to the technical field of protective mechanisms, and in particular relates to a safety protection mechanism for grinding alloy drill bits. Background Technology

[0002] Alloy drill bits are machining tools used on lathes. They possess good hardness and strength, and can maintain the sharpness of the cutting edge during lathe machining, withstand high pressure and high-speed rotation, thereby meeting machining requirements.

[0003] However, when producing alloy drill bits and components, they need to be manually installed in a fixture in a confined space. This process is not only time-consuming, but also poses a certain degree of danger because the lathe is running, resulting in low overall production efficiency and inconvenience.

[0004] To address the aforementioned issues, this application proposes a safety protection mechanism for grinding alloy drill bits. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection mechanism for grinding alloy drill bits, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a safety protection mechanism for grinding alloy drill bits, comprising a main body and a clamping jaw behind it; an inner ring frame, located inside the main body, for batch installation of workpieces through positioning holes inside; the inner ring frame has a clamping sleeve inside for holding the workpieces, thereby achieving the effect of batch workpiece replacement to make full use of idle time; and a transition gear ring, located inside the outer ring frame in front of the main body, for transmitting the rotational power of the first micro motor above the main body to the gear shaft in front of the main body. The gear shaft meshes with the outer side of the gear ring in front of the inner ring frame, for driving the inner ring frame to rotate and switch the workpieces being processed, eliminating the need for manual replacement and thus providing a protective effect.

[0008] Furthermore, the positioning hole is formed on the side away from the main axis in a protruding square groove for engaging the clamping plate mechanism on one side of the clamping sleeve.

[0009] Furthermore, a second micro motor is installed inside the square groove. The screw at its front end connects to a protrusion on one side of the clamping plate mechanism to drive the workpiece to move forward and backward in and out of the processing area.

[0010] Furthermore, the toothed shaft has a two-section stepped structure, and the outer side is provided with a toothed structure. A positioning shaft is provided at the rear of the toothed shaft, which is rotatably installed inside the upper part of the main body.

[0011] Furthermore, the small-diameter toothed shaft section of the toothed shaft is meshed with the inner side of the transition toothed ring.

[0012] Furthermore, the first micro motor has an active gear shaft in front, which is connected to an annular groove behind the adapter gear ring, and the inner side of the annular groove has a protruding tooth structure that meshes with the active gear shaft.

[0013] Furthermore, a groove is formed between the outer ring frame and the main body to mate with the outer convex ring on the outside of the adapter ring to form a rotatable connection.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, by adding an inner ring frame, allows multiple workpieces to be pre-assembled inside the positioning holes via a clamping sleeve during processing, thus achieving the effect of batch processing. Furthermore, the pre-assembly can be performed while the lathe is running automatically, effectively utilizing idle time and improving the efficiency of grinding and processing.

[0016] This invention, by adding an adapter gear ring, can transmit the rotational power of the first micro motor to the gear shaft, thereby driving the inner ring frame to rotate and adjust the placement of the workpiece. This allows multiple workpieces to be processed continuously without manual adjustment, saving time for manual replacement and providing a certain degree of protection for workers, reducing the probability of abnormalities during workpiece replacement.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a safety protection mechanism for grinding alloy drill bits, including a main body 1 and a clamping jaw behind it.

[0029] The inner ring frame 2 is located inside the main body 1. Workpieces are installed in batches through the positioning holes 3 opened inside. The inner ring frame 2 is equipped with a clamp 10 for clamping the workpieces, thereby achieving the effect of batch workpiece replacement and making full use of idle time.

[0030] The adapter gear ring 7 is located on the inner side of the outer ring frame 4 in front of the main body 1. It is used to transmit the rotational power of the first micro motor 9 above the main body 1 to the toothed shaft 6 in front of the main body 1. The toothed shaft 6 meshes with the outer side of the toothed ring 5 in front of the inner ring frame 2. It is used to drive the inner ring frame 2 to rotate and switch the workpiece being processed. No manual replacement is required, thereby forming a protective effect.

[0031] This embodiment provides a protective fixture that can continuously switch workpieces. By adding an inner ring frame 2, the workpieces pre-installed inside the frame 3 can be switched in position through the toothed shaft 6, the adapter toothed ring 7, and the first micro motor 9 on its outer side, so as to achieve the effect of continuously grinding and processing multiple workpieces. This not only avoids frequent workpiece changes, but also protects the workers and prevents abnormalities during workpiece changes and processing.

[0032] The positioning hole 3 is located on the side away from the axis of the main body 1 and is opened in a protruding square groove for docking with the clamping plate mechanism on one side of the clamping sleeve 10, thereby forming a positioning so that the workpiece is installed at a predetermined angle.

[0033] The square groove contains a second micro motor 11 with a screw 12 at the front end, which connects to the spiral groove inside the protrusion 13 on one side of the clamping plate mechanism to drive the workpiece to move back and forth in and out of the processing area.

[0034] The toothed shaft 6 has a two-section stepped structure, and the outer side is provided with a toothed structure. The positioning shaft 8 is provided at the rear of the toothed shaft 6 and is rotatably installed inside the upper part of the main body 1 to maintain the stability of the toothed shaft 6 when it rotates. The small diameter toothed shaft section of the toothed shaft 6 is meshed with the inner side of the adapter toothed ring 7.

[0035] The first micro motor 9 has an active gear shaft 15 in front of it, which is connected to the annular groove behind the adapter gear ring 7. The inner wall of the outer ring of the annular groove has a protruding tooth structure that meshes with the active gear 15.

[0036] Among them, a groove is formed between the outer ring frame 4 and the main body 1 to connect the outer convex ring 14 on the outside of the adapter ring 7 to form a rotatable connection.

[0037] It is understandable that this utility model can continuously grind and process multiple workpieces by frequently changing the workpiece manually. This not only makes use of the idle time when the lathe is running automatically, but also avoids tedious changes, thus forming a certain protection effect and making the processing operation more stable and efficient.

[0038] A specific application of the operation flow of this embodiment is as follows: In use, the workpiece is first clamped by the clamping sleeve 10 and inserted into the positioning hole 3. The clamping plate above the clamping sleeve 10 aligns with the protruding groove on one side of the positioning hole 3 to form a positioning mechanism. At this time, the protrusion 13 is spirally connected to the screw 12. Subsequently, when changing the inner ring frame 2, the inner ring frame 2 is directly inserted into the body 1 and clamped and fixed using the claws at the rear of the body 1. Then, during grinding, the second micro motor 11, via the screw 12 and the protrusion 13 on its outer side, drives the workpiece to move outward to the processing area. When changing the workpiece, the processed workpiece is pushed back. The rotational power released by the first micro motor 9 and its active gear shaft 15 is transferred to the stepped gear shaft at one end of the gear shaft 6 using the adapter gear ring 7. Then, the exposed gear shaft of the gear shaft 6 drives the positioning hole 3 to rotate, so as to rotate another workpiece to be processed to the predetermined position for grinding. After this arrangement, the workpieces only need to be pre-assembled and can be installed in batches inside the main body 1 for continuous batch grinding. This not only makes use of fragmented time, so that grinding and workpiece change are not rushed, but also protects personnel by batch installation and reduces the abnormality rate during workpiece change.
