TECHNICAL FIELD
[0001] The utility model relates to medical equipment processing and manufacturing technical field, especially a kind of medical skeleton packing frame cover precision machining tooling. BACKGROUND
[0002] In the production and manufacturing process of medical kit, right frame cover as its important component, its machining precision and assembly quality directly affect the sealing, stability and service life of medical kit and other key performance indicators. The traditional medical kit right frame cover processing or assembly tooling often has many defects. Some tooling uses simple mechanical clamp, it is difficult to adapt to the complex shape structure of right frame cover, and it is easy to cause scratch, indentation and other damage to the surface of frame cover during fixing process, which affects the appearance quality of product. Moreover, the positioning accuracy of traditional tooling is limited, and it is difficult to achieve accurate positioning control for the key parts of right frame cover, which leads to deviation in subsequent processing or assembly process, increases the scrap rate and rework rate. In addition, the general performance of traditional tooling is poor, and it is necessary to redesign and manufacture tooling for different specifications and models of medical kit right frame cover, which not only increases the production cost, but also prolongs the production cycle, and it is difficult to meet the urgent needs of modern medical equipment manufacturing industry for efficient, high-precision and high-universal production tools. Therefore, it has extremely important practical significance to develop a new type of medical skeleton packing frame cover precision machining tooling. SUMMARY
[0003] The utility model aims at providing a kind of special tooling for medical kit right frame cover in the processing, assembly or detection process, which can accurately position and stably fix medical kit right frame cover, effectively improve the efficiency and quality of medical kit right frame cover related production process, and guarantee the overall performance and reliability of medical kit product, so as to solve the above technical problems.
[0004] To achieve the above technical scheme, the technical scheme of the utility model is as follows: a kind of medical skeleton packing frame cover precision machining tooling is mainly composed of tooling body. The first placing groove and the second placing groove are coaxially arranged on the tooling body, the depth of the first placing groove is much smaller than the depth of the second placing groove, and the depth difference design can adapt to the placing needs of different parts of medical kit right frame cover, and provide preliminary positioning basis for frame cover. The clamping part that can be deformed radially outward is arranged at the center position of the second placing groove, and the unique structure design realizes stable clamping of the key parts of medical kit right frame cover, ensures that the frame cover does not displace or shake during processing, assembly or detection process, so as to ensure the accuracy and reliability of process.
[0005] Further, the tool body, as the basic bearing structure of the whole tool, has sufficient strength and rigidity to withstand various external forces and vibrations generated in the process of machining, assembling, etc., to ensure the stability of the tool as a whole. The coaxial design of the first and second placement grooves enables the medical box right frame cover to be naturally aligned with the center position when placed, which is conducive to subsequent positioning and clamping operations. The first placement groove is relatively shallow and is mainly used to place the edge part or some relatively thin structural parts of the medical box right frame cover. Its shape and size are closely matched with the corresponding parts, which can preliminarily limit the lateral movement of the frame cover. The second placement groove is relatively deep and is used to accommodate the main part or key structure of the medical box right frame cover. Its depth and shape design can ensure the stable placement of the frame cover in the vertical direction and provide a suitable space for the setting of the clamping part.
[0006] Further, the clamping part mainly consists of extrusion blocks, extrusion columns and a lifting power source. The six extrusion blocks are enclosed in a column shape. This structure design can be adapted to the circular or approximately circular key parts of the medical box right frame cover and clamp it from multiple directions. The extrusion blocks are inclined on one side, and the inclined surface is provided with outwardly protruding dovetail blocks. This unique structure design not only increases the contact friction between the extrusion blocks and the frame cover, improves the stability of clamping, but also provides a key connection structure for subsequent cooperation with the extrusion column. The arc surface of the extrusion block is sprayed with a 0.2-micron-thick wear-resistant coating made of high-performance wear-resistant materials such as titanium nitride coating or diamond-like coating, which can effectively reduce the friction and wear between the extrusion blocks and the frame cover during clamping and loosening, prolong the service life of the extrusion blocks, and also avoid the pollution of metal debris and other impurities generated by wear to the medical box right frame cover, ensuring the cleanliness and quality of the product.
[0007] Further, the extrusion column is movably inserted into the extrusion block, and one end of the extrusion column is provided in a circular table shape, and the circular table surface is provided with an inner recessed sliding groove matched with the dovetail block. When the extrusion column moves upward, the dovetail block slides along the sliding groove, so that the extrusion block can deform radially outward, thereby realizing the clamping action of the medical box right frame cover. Second arc surfaces are provided between adjacent sliding grooves. When all the extrusion columns are ejected at the same time, the second arc surfaces and the extrusion blocks reconfigure a columnar body, which can closely fit the internal shape of the medical box right frame cover, further enhancing the stability and uniformity of clamping. The other end of the extrusion column is provided with an inner recessed inclined surface, which is in contact with the output end surface of the lifting power source. This inclined surface contact design can convert the linear motion of the lifting power source into the axial movement of the extrusion column, and can realize uniform force transmission during contact, ensuring the movement synchronization and force uniformity of each extrusion column.
[0008] Further, the lifting power source is selected as a cylinder, which has the advantages of stable output force, convenient control and fast response speed, and can meet the requirements of the clamping part on power. The output end of the cylinder is detachably provided with a push block, one end of the push block is provided with a slope, the slope is matched with the inner concave slope of the extrusion column, and by adjusting the shape and size of the push block, the ejection height and speed of the extrusion column can be conveniently changed, so that the accurate control of the clamping force and the clamping speed is realized, so as to adapt to the clamping requirements of the medical box right frame cover of different specifications and materials.
[0009] Further, the negative pressure suction hole arranged on the first placing groove can generate suction force by applying negative pressure when the medical box right frame cover is placed, so that the edge part of the frame cover is firmly adsorbed on the bottom of the first placing groove, and the stability of the frame cover on the tool is further enhanced. The negative pressure suction hole is connected with an external negative pressure source, when the negative pressure source is started, air is sucked out from the gap between the first placing groove and the frame cover, so that a negative pressure environment is formed in the first placing groove, and the frame cover is tightly adsorbed under the action of the air pressure difference. The negative pressure adsorption and the clamping action of the clamping part are matched with each other to form a double fixing mechanism, which effectively prevents the medical box right frame cover from being displaced or shaken due to external force during processing, assembly or detection, and greatly improves the fixing reliability and precision of the tool.
[0010] In use of the medical bone boxing frame cover precision machining tool, first, the medical box right frame cover is placed in the first placing groove and the second placing groove of the tool body, since the shape of the placing groove is matched, the frame cover can be naturally in a substantially correct position. Then, the negative pressure source is started, and the negative pressure adsorbs the edge part of the frame cover on the bottom of the first placing groove through the negative pressure suction hole, and the position of the frame cover is preliminarily fixed. Then, the cylinder is started, the output end of the cylinder pushes the push block to move upward, the slope of the push block is in contact with the inner concave slope of the extrusion column and pushes the extrusion column to move upward. With the upward movement of the extrusion column, the dovetail protrusions on the extrusion block slide along the sliding groove of the extrusion column, so that the extrusion block deforms outward along the radial direction, and the key parts of the medical box right frame cover are clamped from multiple directions. In the whole process, the adsorption force of the negative pressure suction hole and the clamping force of the clamping part are coordinated with each other, which not only ensures that the frame cover will not be displaced in the horizontal direction and the vertical direction, but also avoids the loosening of the frame cover due to the failure of a single fixing mode. After the processing, assembly or detection is completed, the output end of the cylinder is retracted, the extrusion block restores to the original state under the action of the elastic restoring force, the clamping of the frame cover is released, then the negative pressure source is turned off, and the adsorption force of the negative pressure suction hole is released, so that the medical box right frame cover can be taken out from the tool.
[0011] Compared with the prior art, the utility model has the advantages of:
[0012] 1) The utility model discloses a double-groove cooperative positioning: the first placing groove and the second placing groove coaxially arranged on the tool body, through the depth difference and shape matching, the multiple parts of the medical box right frame cover are cooperatively positioned. The first placing groove places and preliminarily positions the frame cover edge part, and the second placing groove contains and positions the frame cover main part, and the approximate position of the frame cover in the vertical direction and the key position is determined. This double-groove design enables the medical box right frame cover to quickly and accurately find the correct position when placed, reduces the workload and error of manual adjustment, provides a high-precision positioning basis for subsequent fixing and processing, assembly or detection operation, and effectively improves the consistency and quality stability of the product.
[0013] 2) Precise clamping with clamping part: the unique structure design of the clamping part ensures the precise clamping of the key parts of the medical box right frame cover. The columnar structure enclosed by six extrusion blocks can tightly fit the circular or approximately circular key parts of the frame cover, uniformly applies clamping force from multiple directions, and avoids deformation or displacement of the frame cover caused by uneven local stress. The dovetail protrusion on the extrusion block cooperates with the sliding groove of the extrusion column, so that the radial deformation of the extrusion block can be accurately controlled. According to different clamping requirements, the extrusion column height is adjusted, and the clamping force can be accurately adjusted. Moreover, the second arc surface of the adjacent extrusion column and the columnar body reconstructed by the extrusion block when extruding further enhance the adaptability to the internal shape of the frame cover, improve the stability and reliability of clamping, so that the medical box right frame cover can always maintain accurate position and posture during processing, assembly or detection, significantly reducing the scrap rate and rework rate.
[0014] 3) The structure design of the clamping part makes it convenient to adjust the clamping force. By adjusting the air pressure of the air cylinder and the stroke of the push block, the appropriate clamping force can be accurately set according to the different materials, sizes and process requirements of the medical box right frame cover. For the frame cover with soft material or small size, the air pressure and push block stroke can be reduced to reduce the clamping force and avoid damage to the frame cover; for the frame cover with hard material or large size, the air pressure and push block stroke can be increased to increase the clamping force and ensure the fixation reliability of the frame cover. This adjustable clamping force feature makes the tooling widely applicable to the processing, assembly or detection process of various specifications and models of medical box right frame covers, improves the universality of the tooling, reduces the production cost, and reduces the frequent replacement due to product model changes.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0018] In order for those skilled in the art to better understand the utility model scheme, the utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0019] Please refer to the accompanying Figure 1 As shown in the figure: a medical bone box frame cover precision machining tool, including tool body 1, the coaxial first placement groove 2 and second placement groove 3 are arranged on the tool body 1, the depth of the first placement groove 2 is much smaller than the depth of the second placement groove 3, the second placement groove 3 is provided with a clamping part 4 which can be deformed radially outward. The first placement groove and the second placement groove coaxially arranged on the tool body have unique ingenuity in depth difference and shape design. The first placement groove is shallow in depth, which is used for bearing the edge part of the right frame cover of the medical box, can effectively limit its displacement in the horizontal direction, and provides preliminary transverse positioning. The second placement groove is larger in depth, which can accommodate the main key part of the frame cover, ensure its stable placement in the vertical direction, and provide a spatial basis for the action of the subsequent clamping part. The two cooperate to make the right frame cover of the medical box fall into the predetermined position naturally and accurately according to its own shape when placed, greatly reduce the time and error of manual adjustment, lay a high-precision positioning cornerstone for subsequent machining, detection or assembly process, and effectively guarantee the consistency and quality stability of product production.
[0020] On the basis of the above embodiment, the clamping part 4 includes an extrusion block 41 enclosed in a columnar shape, a movable extrusion column 42 is movably inserted on the extrusion block 41, and a lifting power source 43 is arranged on one side of the extrusion column 42.
[0021] On the basis of the above embodiment, six said extrusion blocks 41 are enclosed into a columnar shape; one side of said extrusion blocks 41 is arranged obliquely, and an outwardly protruding dovetail block is arranged on the inclined surface. The core component of the clamping part is arranged in a columnar shape, and the design of the six extrusion blocks can closely fit the circular or approximately circular key part of the right frame cover of the medical kit, and uniformly apply clamping force from multiple directions, effectively avoiding the risk of frame cover deformation or displacement caused by uneven local stress. The oblique surface on one side of the extrusion block and the outwardly protruding dovetail block not only enhance the friction when in contact with the frame cover, ensuring the reliability of clamping, but also create a unique structural basis for the precise cooperation with the extrusion column. Through the coordinated interaction between the inner recessed sliding groove of the circular truncated cone-shaped end and the dovetail block, the precise control of the radial deformation of the extrusion block is realized. When the extrusion column moves under the driving of the lifting power source, the dovetail block stably slides in the sliding groove, prompting the extrusion block to deform radially outward, thereby implementing precise and stable clamping action on the right frame cover of the medical kit. The second arc surface between adjacent sliding grooves reconstructs a columnar body with the extrusion block during the ejection of the extrusion column, further optimizing the fitting degree with the internal shape of the frame cover, significantly improving the stability and uniformity of clamping, so that the frame cover always maintains a precise position and attitude during the entire processing, testing or assembly process, greatly reducing the scrap rate and rework rate.
[0022] On the basis of the above embodiment, a layer of wear-resistant coating with a thickness of 0.2 microns is sprayed on the arc surface of the extrusion block 41. The arc surface of the extrusion block is carefully sprayed with a 0.2-micron-thick wear-resistant coating. In the process of frequent clamping and unclamping operations, repeated friction and contact stress between the right frame cover of the medical kit and the extrusion block is inevitable. Without effective protective measures, the surface of the extrusion block is prone to wear and tear, which not only affects the fitting accuracy of the extrusion block and the frame cover, leading to uneven distribution of clamping force and reducing the fixing reliability of the tool, but also shortens the service life of the extrusion block and the entire tool. The wear-resistant coating is made of high-performance wear-resistant materials such as titanium nitride and diamond-like carbon, which has extremely high hardness, extremely low friction coefficient and excellent chemical stability. It can effectively resist mechanical wear and tear during friction, reduce the generation and accumulation of friction heat, prevent material softening or phase change caused by high temperature, and also resist the erosion of external environmental factors such as humidity and corrosive gases.
[0023] On the basis of the above embodiment, the extrusion column 42 is circular truncated cone-shaped at one end, and the circular truncated cone surface is provided with an inner recessed sliding groove matched with the dovetail block; a second arc surface is arranged between adjacent sliding grooves; during ejection, the second arc surfaces and the extrusion blocks 41 reconstruct a columnar body; the other end of the extrusion column 42 is provided with an inner recessed inclined surface; and the inclined surface is in surface contact with the lifting power source 43.
[0024] On the basis of the above embodiment, the lifting power source 43 is a cylinder; the output end of the cylinder is detachably provided with a push block; and one end of the push block is provided with a slope.
[0025] On the basis of the above embodiment, the first placing groove 2 is provided with a negative pressure suction hole. The negative pressure suction hole and the clamping part on the first placing groove constitute a perfect cooperative fixing mechanism, which provides comprehensive and multi-level solid protection for the stable operation of the right frame cover of the medical kit in the tooling. When the negative pressure suction hole is connected with the external negative pressure source and started, a local negative pressure environment is quickly formed in the first placing groove, and the strong air pressure difference tightly adsorbs the edge part of the right frame cover of the medical kit to the bottom of the first placing groove, thereby exerting a stable adsorption force in the vertical direction and effectively limiting the jumping or vertical displacement tendency of the frame cover. At the same time, the clamping part exerts a radial clamping force on the key part of the frame cover to firmly lock the frame cover in the horizontal direction. The two complement each other and benefit each other. Neither the cutting force, vibration impact encountered in the machining process, nor the assembly stress in the assembly process, nor the measurement interference force in the detection process can break through this cooperative fixing defense line, so that the right frame cover of the medical kit always maintains the precise position and stable posture. This cooperative fixing mechanism not only greatly improves the fixing reliability and precision of the tooling, effectively avoids the machining errors, assembly defects or detection deviations caused by the displacement or shaking of the frame cover, ensures the consistency and stability of the product quality, but also significantly improves the safety and operability of the production process, reduces the risk of safety accidents caused by unstable workpiece fixation, provides indispensable key technical support for medical kit manufacturing enterprises to create high-quality products and build efficient and safe production environment.
[0026] The medical kit right frame cover to be processed, assembled or detected is carefully placed in the first and second placing grooves of the tool body, with the edge part of the frame cover in the first placing groove and the main body part in the second placing groove. Due to the shape matching of the placing grooves, the frame cover can naturally be in a roughly correct position, but it is not yet completely fixed. Start negative pressure suction: connect the negative pressure source with the negative pressure suction hole of the first placing groove, start the negative pressure source, and make the gas sucked out from the gap between the first placing groove and the frame cover, forming negative pressure at the negative pressure suction hole. Observe that the medical kit right frame cover is adsorbed at the bottom of the first placing groove under the action of negative pressure, at this time the frame cover is preliminarily fixed in the vertical direction, and its position stability is enhanced, but it still has a certain degree of freedom in the horizontal direction. Activate the clamping part: start the air cylinder, the output end of the air cylinder pushes the push block to move upward, the inclined surface of the push block contacts with the inner recessed inclined surface of the extrusion column and pushes the extrusion column to move upward. With the upward movement of the extrusion column, the dovetail protrusions on the extrusion block slide along the sliding groove of the extrusion column, so that the extrusion block deforms outward in the radial direction, clamping the key parts of the medical kit right frame cover from multiple directions. By adjusting the air pressure of the air cylinder and the stroke of the push block, the size of the clamping force can be accurately controlled to ensure that the clamping force is moderate, which can firmly fix the medical kit right frame cover without causing excessive extrusion or damage to it. At this time, the medical kit right frame cover is reliably fixed in the horizontal and vertical directions, and subsequent processing, assembly or detection operations can be performed. Complete the operation and take out the frame cover: when the processing, assembly or detection is completed, first make the output end of the air cylinder retract, and the extrusion block restores to its original state under the action of its own elastic restoring force, releasing the clamping of the frame cover. Then turn off the negative pressure source to release the adsorption force of the negative pressure suction hole. Carefully take out the medical kit right frame cover from the first and second placing grooves of the tool, check the surface quality and processing precision of the frame cover, and prepare for the next cycle of operation. The tool as a whole adopts a modular design concept, and each component has clear and relatively independent functions, and the connection and cooperative working mode between them is clear and efficient. The tool body, the first placing groove, the second placing groove, the clamping part and the negative pressure suction hole and other components each bear a unique functional task. This design makes the tool show excellent adaptability and expandability when facing different production needs or process improvements. For example, if the placing accuracy of different size medical kit right frame covers needs to be optimized, the shape and size of the first and second placing grooves can be adjusted accordingly, without interfering with the normal operation of the clamping part and other components; if the clamping performance of the clamping part needs to be improved, the material of the extrusion block, the shape of the dovetail protrusions, the sliding groove structure of the extrusion column or the parameters of the lifting power source can be adjusted and optimized separately, without the need to redesign and manufacture the entire tool on a large scale. This good versatility and expandability not only prolongs the service life of the tool and reduces maintenance costs, but also enables the tool to better adapt to the trend of rapid development and continuous innovation of the medical kit manufacturing industry, providing strong technical support for the long-term stable production of enterprises.

Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application.
