Description

Technical Field

[0001] The utility model relates to the technical field of medical bone plate processing, in particular to a single-sided automatic clamp used for bone plate processing. Background Art

[0002] A fixture is a device used to fix the object to be processed in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture. In the medical industry, bone plate products are generally clamped manually. In the traditional bone plate processing process, the clamping process requires manual clamping and loosening of the product, which is cumbersome and time-consuming. Workers have been clamping manually, which is relatively inefficient and not conducive to the physical and mental health of workers. At present, there is no dedicated automatic door fixture. Bone plate products usually need to be machined. The traditional clamping method often takes a lot of time and manpower, and it is difficult to ensure the accuracy of clamping. It is easily affected by human factors and may have operational errors. In addition, the traditional clamping process may be unstable and inaccurate in manual operation. Because the clamping force depends on the worker's manual work, the clamping state of different workers or the same worker in different time periods is not uniform, which can easily cause the bone plate product to be clamped excessively or too loosely, affecting the processing size, resulting in certain differences in the processed bone plate products, and even causing scrapping or damage to the processing tool.

[0003] There are already some solutions for clamping fixtures for bone plate products. Common solutions include semi-automatic clamping fixtures. Although semi-automatic clamping fixtures can achieve a certain degree of automation, they still require operators to operate them. They cannot completely solve the problems in the clamping process, which can easily lead to unsatisfactory clamping results. In addition, in terms of market demand, as the demand for medical bone plate processing continues to increase, the demand for efficient and accurate clamping fixtures is becoming more and more urgent. The fixtures in the existing technology often have problems such as low efficiency and unstable quality, and cannot meet the market's requirements for high-quality and efficient processing of bone plate products, as well as the high requirements for the accuracy and quality of the plates.

[0038] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figures 1 to 6 As shown in the figure, the utility model discloses a single-sided automatic clamp for bone plate processing, including a clamp body 1, a fixed clamping block 2, a movable clamping block 3, an inclined wedge block 4 and a control member 5. The fixed clamping block 2 is fixedly connected to the clamp body 1, and the movable clamping block 3 is movably connected to the clamp body 1. Such an arrangement can change the relative distance between the movable clamping block 3 and the fixed clamping block 2, and the opposite surfaces of the movable clamping block 3 and the fixed clamping block 2 can selectively clamp the bone plate 100. The side of the movable clamping block 3 away from the fixed clamping block 2 is set as a matching bevel 31, and correspondingly, a guide bevel 41 is provided on the inclined wedge block 4. The guide bevel 41 and the matching bevel 31 can cooperate and abut and slide relative to each other, and the control part 5 installed on the clamp body 1 can control the inclined wedge block 4 to reciprocate in the vertical direction; the movable clamping block 3 has a clamping process and a loosening process. When the inclined wedge block 4 moves vertically upward, the movable clamping block 3 can move in the direction away from the fixed clamping block 2, and the movable clamping block 3 is in the loosening process. At this time, the bone plate 100 on the single-sided automatic clamp for bone plate processing can be replaced; when the inclined wedge block 4 moves vertically downward, the movable clamping block 3 can move in the direction close to the fixed clamping block 2, and the movable clamping block 3 is in the clamping process, and the bone plate 100 is stably clamped and fixed. In summary, the control member 5 can realize automatic cyclic clamping of the bone plate 100, the operation process is simpler, manpower can be saved, uneven clamping caused by manual clamping can be avoided, the efficiency and accuracy of the bone plate 100 processing can be improved, and the production cost and scrap rate can be reduced. The unilaterally adjusted mobile clamping block 3 can provide more stable and uniform clamping during processing, reduce the quality difference of the bone plate 100 products, realize a standardized clamping process, improve the consistency and stability of the bone plate 100, and meet the market's high-quality demand for the bone plate 100. For example, in addition to the field of bone plate processing, other similar processing fields that require clamping can be applied to this automatic clamp, which will bring technological progress to related industries and improve market competitiveness.

[0041] Specifically, the fixed clamping block 2 is detachably connected to the fixture body 1, and the movable clamping block 3 is detachably connected to the fixture body 1. The fixed clamping block 2 and the movable clamping block 3 can be flexibly replaced. When the wear of the two causes the single-sided automatic clamp used for bone plate processing to be unable to accurately clamp the bone plate 100, they can be replaced in time to avoid overall scrapping, which can effectively save costs. In addition, a fixture body 1 can also be installed with different matching fixed clamping blocks 2 and movable clamping blocks 3 to clamp bone plates 100 of different sizes, which can improve the scope of application of the single-sided automatic clamp used for bone plate processing.

[0042] Furthermore, in order to better link the inclined wedge block 4 and the mobile clamping block 3, a first slide rail 311 is provided on the matching inclined surface 31, and a first slide groove 411 is correspondingly provided on the guiding inclined surface 41. The first slide rail 311 can be placed in the first slide groove 411 to slide relatively, so that the inclined wedge block 4 and the mobile clamping block 3 can be slidably plugged. When the inclined wedge block 4 moves vertically upward, it drives the mobile clamping block 3 to move away from the fixed clamping block 2, and the mobile clamping block 3 can be more stably in the loosening process, ensuring the continuous stability of the automatic loosening action. For example, Figure 5 and Figure 6 As shown, the first slide rail 311 is configured as a T-shaped block, and the first slide groove 411 is correspondingly configured as a T-shaped groove, so as to maintain the connection stability between the inclined wedge block 4 and the movable clamping block 3 and prevent slipping.

[0043] Specific as Figure 3 As shown in the figure, the fixed clamping block 2 is provided with a first contoured half groove 21, and the movable clamping block 3 is provided with a second contoured half groove 32. When the movable clamping block 3 is in the clamping process, the positions of the first contoured half groove 21 and the second contoured half groove 32 can correspond to the placement of the bone plate 100. On the one hand, the bone plate 100 is clamped in the two contoured half grooves, which can limit the position of the bone plate 100 and ensure that the clamping effect is more stable after the bone plate 100 is placed in place; on the other hand, the bottom of the first contoured half groove 21 and the second contoured half groove 32 provide a certain bearing capacity for the bone plate 100. When the bone plate 100 product is installed on a single-sided automatic clamp for bone plate processing, the bottom suspended part is reduced, thereby reducing the possibility of the bone plate 100 being deformed by clamping.

[0044] In this embodiment, the unilateral automatic clamp for bone plate processing includes a first limit block 6, which is fixedly connected to the clamp body 1. One end of the movable clamping block 3 is flush with one end of the fixed clamping block 2, and both are abutted against the same surface of the first limit block 6, ensuring that the movable clamping block 3 and the fixed clamping block 2 are aligned, preventing misalignment of the two and causing unstable clamping, and further improving the accuracy of the clamping position.

[0045] Specific as Figure 1 and Figure 3 As shown in the figure, the single-sided automatic clamp for bone plate processing includes a guide member 7, which is vertically connected to the clamp body 1, and the inclined wedge block 4 is provided with a guide hole, and the guide member 7 can be inserted into the guide hole. The inclined wedge block 4 is slidably connected to the guide member 7, and the outer diameter of the guide member 7 is matched with the inner diameter of the guide hole. The guide member 7 limits the inclined wedge block 4, which can ensure that the inclined wedge block 4 reciprocates in the vertical direction, further enhancing the movement stability of the single-sided automatic clamp for bone plate processing.

[0046] Optionally, the movable clamping block 3 is provided with a second slide rail, and the clamp body 1 is provided with a second slide groove. The second slide rail can be placed in the second slide groove and slidably connected to the clamp body 1. The movable clamping block 3 and the clamp body 1 slide relative to each other in the horizontal direction, so as to more accurately control the clamping distance, as well as the direction and angle of the relative force exerted on the bone plate 100 by the movable clamping block 3 and the fixed clamping block 2 during clamping.

[0047] Preferably, when the mobile clamping block 3 is in the clamping process, the mobile clamping block 3 and the fixed clamping block 2 gradually move relative to each other to clamp the bone plate 100. At this time, a safety gap is arranged between the mobile clamping block 3 and the fixed clamping block 2, so as to avoid the mobile clamping block 3 and the fixed clamping block 2 from interfering with each other and colliding with each other, thereby maintaining the use safety and clamping accuracy of the unilateral automatic clamp used for bone plate processing, extending the service life of the unilateral automatic clamp used for bone plate processing, and preventing damage to the unilateral automatic clamp used for bone plate processing caused by operating errors.

[0048] It can be understood that the unilateral automatic clamp for bone plate processing includes a second limit block 8 and a third limit block 9, wherein the second limit block 8 is in close contact with the fixed clamping block 2, and the second limit block 8 is fixedly connected to the clamp body 1, which not only limits the clamping direction of the fixed clamping block 2, further stabilizes the structure of the fixed clamping block 2, but also protects the force strength of the fixed clamping block 2 along the clamping direction; the third limit block 9 is in contact with the oblique wedge block 4, the oblique wedge block 4 can slide relative to the third limit block 9, and the third limit block 9 is fixedly connected to the clamp body 1. The function of the third limit block 9 is similar to that of the aforementioned second limit block 8, which further limits the oblique wedge block 4 and maintains its movement stability. At the same time, it also improves the force strength of the oblique wedge block 4, and the overall structure of the unilateral automatic clamp for bone plate processing is more stable and reliable.

[0049] Specific as Figure 2 As shown in the figure, the control part 5 is configured as a cylinder, and the cylinder is embedded in the back side of the clamp body 1. The clamp body 1 is also provided with an air pipe groove 11 and a pressure block 10. The air pipe groove 11 is used to place the air pipe connected to the cylinder, and the two ends of the pressure block 10 are respectively connected to the two opposite groove walls of the air pipe groove 11 to press and limit the air pipe. The air pipe is placed between the air pipe groove 11 and the pressure block 10. The pressure block 10 is flush with the bottom of the clamp body 1 or the pressure block 10 is embedded in the clamp body 1 to maintain the flatness of the back side of the clamp body 1. The single-sided automatic clamp for bone plate processing can be conveniently and stably placed and fixed on an operating table of any level. The single-sided automatic clamp for bone plate processing has a regular appearance and structure, which is convenient for storage.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
