Description

Technical Field

[0001] This utility model relates to the field of auxiliary processing and provides a support and clamping device for spiral groove parts. Background Technology

[0002] In the production of medical tubing, stainless steel spiral grooved parts are key manufacturing components due to their unique shape and processing requirements. When processed using CNC machining equipment, the material is subjected to forces that cause deformation, leading to dimensional instability and affecting product quality.

[0003] While existing tooling solutions provide some support and rotational power, they still fall short in terms of deformation prevention, positioning, and versatility.

[0004] Specifically, existing tooling solutions often only provide clamping and rotational power at one end, while the other end is supported by an ejector pin. Although better solutions add support points at the bottom and middle of the product to reduce deformation and improve positioning accuracy, they still fail to completely solve the deformation and stability problems.

[0005] Furthermore, existing tooling requires manual adjustment of multiple support points when changing products of different diameters, increasing the workload. Poor positioning accuracy necessitates re-alignment each time a product is changed, leading to low production efficiency. Moreover, this tooling lacks versatility and is unsuitable for products of various diameters, increasing production costs and complexity. Utility Model Content

[0006] This utility model provides a support and clamping device for spiral groove parts, which solves the problem of low positioning and clamping efficiency of spiral groove parts in related technologies.

[0007] This utility model embodiment provides a spiral groove part support and clamping device, including: Support module, the support module being adapted to be mounted on the machine tool table; A positioning module is detachably connected to the top of the support module, and the positioning module has a circular groove for supporting and positioning the spiral groove part.

[0008] According to one embodiment of the present invention, a positioning structure is provided between the positioning module and the support module to achieve rapid positioning of the positioning module on the support module.

[0009] According to one embodiment of the present invention, the positioning structure includes a positioning boss disposed at the bottom of the positioning module and a positioning groove disposed at the top of the support module and cooperating with the positioning boss.

[0010] According to one embodiment of the present invention, the positioning module and the support module are detachably fixedly connected by fasteners.

[0011] According to one embodiment of the present invention, the positioning module is provided with a threaded through hole, the support module is provided with a threaded hole corresponding to the threaded through hole, and the fastener is a screw that passes through the threaded through hole and is screwed into the threaded hole.

[0012] According to one embodiment of the present invention, the positioning module is further provided with a chip removal groove that communicates with the circular groove.

[0013] According to one embodiment of the present invention, there are multiple chip removal grooves, which are spaced apart along the length direction of the circular groove.

[0014] According to one embodiment of the present invention, the cross-sectional profile of the circular groove is an arc shape larger than a semicircle, so as to achieve a wrapping support for the spiral groove part.

[0015] According to one embodiment of the present invention, the support module includes a fixed base plate and a raised boss disposed on the fixed base plate, and the positioning module is installed on the top surface of the raised boss.

[0016] According to one embodiment of the present invention, the fixed base plate is adapted to be fixed on the machine tool table by means of a T-block.

[0017] The spiral groove part support and clamping device provided in this embodiment of the utility model achieves a wrap-around support through a circular groove larger than a semicircle, increasing the contact area between the part and the positioning module, and evenly distributing the cutting force to the inner wall of the groove. This effectively suppresses part deformation and ensures that the dimensional accuracy of the spiral groove, such as groove depth, pitch, and roundness, meets the requirements after machining, reducing the scrap rate caused by deformation. It is especially suitable for the stringent precision requirements of medical hose production. The fixed base plate and raised boss of the support module are integrally formed, with strong overall rigidity, which can withstand the high-frequency vibration and cutting force impact during machine tool processing, avoiding deformation of the support structure itself. The tight fit and rigid fixation between the positioning module and the support module further ensure that the part does not loosen or shift after clamping. During the processing, the axis of the part is always coaxial with the axis of the machine tool spindle, avoiding the positional shift of the spiral groove caused by positioning deviation, and improving the surface quality of the machined part. Traditional tooling requires manual adjustment of multiple support points to adapt to parts of different diameters, which is cumbersome and has low positioning accuracy. This device can quickly adapt to stainless steel spiral groove parts of various diameters by changing the positioning module with different circular groove sizes, without adjusting the overall structure of the support module. The replacement of the positioning module only requires the removal of a few screws, which can be completed by a single person in a short time, greatly shortening the equipment adjustment time, improving the efficiency of production line switching, and reducing the tooling investment cost for processing multi-specification parts.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figures 1 to 5 As shown, this utility model embodiment provides a spiral groove part support and clamping device, including: Support module 100, which is suitable for mounting on the machine tool table; The positioning module 102 is detachably connected to the top of the support module 100, and the positioning module 102 has a circular groove 104 for supporting and positioning the spiral groove part.

[0027] According to the embodiment of this utility model, the spiral groove part support and clamping device achieves a wrapping support through a circular groove 104 larger than a semicircle, increasing the contact area between the part and the positioning module 102, and evenly distributing the cutting force to the inner wall of the groove, effectively suppressing part deformation, ensuring that the dimensional accuracy of the spiral groove, such as groove depth, pitch, and roundness, meets the requirements after processing, and reducing the scrap rate caused by deformation. It is especially suitable for the stringent requirements for part precision in the production of medical hoses. The fixed base plate 114 and the raised boss 116 of the support module 100 are integrally formed, with strong overall rigidity, which can withstand the high-frequency vibration and cutting force impact during machine tool processing, and avoid deformation of the support structure itself; the tight fit and rigid fixation of the positioning module 102 and the support module 100 further ensure that the part does not loosen or shift after clamping, and the axis of the part is always coaxial with the axis of the machine tool spindle during processing, avoiding the positional shift of the spiral groove caused by positioning deviation, and improving the surface quality of the processed part. Traditional tooling requires manual adjustment of multiple support points to accommodate parts of different diameters, which is cumbersome and results in low positioning accuracy. This device, by replacing positioning modules 102 with different sizes of circular grooves 104, can quickly adapt to stainless steel spiral groove parts of various diameters without adjusting the overall structure of the support module 100. Replacing the positioning module 102 only requires removing a few screws, which can be completed by a single person in a short time, significantly reducing equipment adjustment time, improving production line changeover efficiency, and reducing tooling investment costs for processing multi-specification parts.

[0028] Please continue reading Figures 1 to 5 The spiral groove part support and clamping device provided in this embodiment of the utility model addresses the needs of stainless steel spiral groove parts in CNC machining for anti-deformation, precise positioning and versatility. Through the core design of modular support and detachable positioning, it solves the problems of low positioning efficiency and easy deformation of parts caused by traditional tooling.

[0029] The support module 100 is a rigid metal component with sufficient weight and structural strength to prevent self-displacement caused by machine tool vibration. Its core function is to provide a stable installation reference for the positioning module 102 and adapt it to the machine tool table.

[0030] The support module 100 includes a fixed base plate 114 and a raised boss 116. The fixed base plate 114 is a rectangular flat plate with a fixed interface on its surface that is compatible with the machine tool table. It is fixed to the machine tool table by T-blocks and bolts to ensure that there is no lateral or longitudinal movement after installation. The raised boss 116 is integrally formed in the center of the top surface of the fixed base plate 114. Its height is designed according to the processing position requirements of the parts. The top surface is a precision-machined flat reference surface used to install the positioning module 102. It can be adjusted in height to adapt to the processing height requirements of parts with different diameters.

[0031] When installing the fixed base plate 114, it is necessary to ensure that its top surface is parallel to the axis of the machine tool spindle. After calibration with a level, the T-block is tightened to avoid the positional deviation between the subsequent positioning module 102 and the part due to the tilt of the base plate. The flatness of the top surface of the raised boss 116 is ground to reduce the fitting gap with the positioning module 102 and improve the support stability.

[0032] The positioning module 102 is a detachable metal component, which is fixed to the top of the support module 100 by a concave-convex positioning structure and fasteners. Its core function is to achieve the covering support and precise positioning of the spiral groove part through the circular groove 104.

[0033] The circular groove 104 is formed on the top surface of the positioning module 102 and extends along the length of the module. Its cross-section is an arc shape larger than a semicircle. The inner diameter of the arc is precisely matched with the outer diameter of the spiral groove part to be processed. After the part is placed in the groove, the inner wall of the arc fits tightly with the outer circumference of the part, forming a covering support, which can limit the radial runout and axial movement of the part, and only retain the rotational freedom of the part around its own axis. The inner wall of the groove is smoothly polished and has no sharp edges to avoid scratching the surface of the part or hindering the discharge of chips.

[0034] The positioning module 102 has a positioning boss 106 at the bottom, which precisely matches the positioning groove 108 on the top surface of the raised boss 116 of the support module 100 to achieve rapid initial positioning. The positioning module 102 has a threaded through hole 110 on its side or top surface, and the support module 100 has a threaded hole at the corresponding position. By screwing the screw through the through hole into the threaded hole, the two are rigidly fixed. When disassembling, the positioning module 102 can be replaced by simply rotating the screw in the opposite direction, which is suitable for spiral groove parts of different diameters.

[0035] According to one embodiment of the present invention, a positioning structure is provided between the positioning module 102 and the support module 100 to achieve rapid positioning of the positioning module 102 on the support module 100.

[0036] In one embodiment of this utility model, the positioning structure is a concave-convex mating structure, respectively formed on the bottom of the positioning module 102 and the top of the support module 100. The positioning structure at the bottom of the positioning module 102 can be a cylindrical boss or a rectangular protrusion. The size and shape of the boss / protrusion are precision machined to ensure a smooth surface without burrs. A positioning groove 108 adapted to the boss / protrusion is provided at the corresponding position on the top of the support module 100. The depth of the groove is slightly greater than the height of the boss / protrusion to avoid interference during mating. During assembly, the boss / protrusion at the bottom of the positioning module 102 is aligned with the positioning groove 108 on the top of the support module 100, and it is lowered vertically to complete the initial positioning without repeated adjustments. After positioning, the connecting holes of the positioning module 102 and the support module 100 can be automatically aligned, facilitating subsequent fastener fixing.

[0037] By setting up a positioning structure, positioning can be quickly completed through the interlocking of concave and convex parts without the need for manual measurement or scribing alignment. Compared with traditional manual positioning methods, this is especially suitable for scenarios involving batch replacement of positioning modules 102, improving overall processing efficiency. The precision-machined concave and convex structure ensures minimal deviation in each positioning, avoiding positioning offsets caused by manual adjustments. This prevents positional deviations after clamping spiral groove parts, ensuring consistency in processing dimensions and reducing scrap rates. Positioning operations can be performed without specialized technicians; novices can master the skill with minimal training, reducing reliance on skilled workers, lowering labor costs, and preventing module damage due to operational errors.

[0038] According to one embodiment of the present invention, the positioning structure includes a positioning boss 106 disposed at the bottom of the positioning module 102, and a positioning groove 108 disposed at the top of the support module 100 and cooperating with the positioning boss 106.

[0039] In one embodiment of this utility model, the positioning boss 106 is a circular boss, integrally formed at the bottom center of the positioning module 102. The outer peripheral surface of the boss is smoothed, without obvious steps or burrs. The positioning groove 108 is a circular groove, formed at the top center of the support module 100. The inner diameter of the groove is precisely matched with the outer diameter of the positioning boss 106, with minimal gap, ensuring no radial wobble after the boss is embedded. After the boss is fully embedded in the groove, the bottom surface of the positioning module 102 and the top surface of the support module 100 are tightly fitted, with no gaps. In addition, the top surface of the positioning boss 106 is perpendicular to the bottom surface of the positioning module 102, and the bottom surface of the positioning groove 108 is parallel to the top surface of the support module 100, further ensuring the perpendicularity after mating and preventing the positioning module 102 from tilting.

[0040] The tight fit between the circular boss and the groove restricts the radial movement of the positioning module 102. Even if the spiral groove part is subjected to cutting forces during machining, the positioning module 102 will not shift, ensuring the stability of the part's position during machining and improving the machining accuracy of the spiral groove. The depth ratio design of the boss and groove ensures a tight fit between the positioning module 102 and the support module 100, avoiding vibration caused by gaps and reducing the impact of vibration on the surface quality of the machined part. The circular structure distributes force evenly, and the cutting force is uniformly transmitted through the contact surface between the boss and the groove during machining, avoiding structural damage caused by localized force concentration and extending the service life of the positioning structure.

[0041] According to one embodiment of the present invention, the positioning module 102 and the support module 100 are detachably fixedly connected by fasteners.

[0042] In one embodiment of this utility model, the fastener is a standardized connecting component. Both the positioning module 102 and the support module 100 have corresponding connecting holes: the connecting hole on the positioning module 102 is a through hole, and the connecting hole on the support module 100 is an internally threaded hole, with the axes of the through hole and the threaded hole coinciding. During assembly, the fastener is passed through the through hole of the positioning module 102 and screwed into the threaded hole of the support module 100, achieving fixation through thread engagement. During disassembly, the positioning module 102 and the support module 100 are separated by rotating the fastener in the opposite direction, without damaging any components. There are 24 fasteners symmetrically distributed along the central axis of the positioning module 102, ensuring that the positioning module 102 is subjected to uniform force after fixing, preventing tilting or deformation.

[0043] Compared to welded or integrated structures, detachable fastener connections allow for more flexible replacement of the positioning module 102. Changing to different specifications of the positioning module 102 can be completed in just a few minutes, significantly reducing equipment adjustment time and improving production line changeover efficiency. Symmetrically distributed fasteners provide uniform clamping force, ensuring a tight fixation between the positioning module 102 and the support module 100. Even under high-speed machining or high cutting force conditions, loosening will not occur, preventing displacement of parts during machining and ensuring machining accuracy. The fasteners are standardized components and can be directly replaced when damaged, eliminating the need to replace the entire positioning module 102 or support module 100, reducing maintenance costs. Simultaneously, the detachable structure facilitates individual repair of the positioning module 102 or support module 100, extending the overall service life of the device.

[0044] According to one embodiment of the present invention, the positioning module 102 is provided with a threaded through hole 110, the support module 100 is provided with a threaded hole corresponding to the threaded through hole 110, and the fastener is a screw that passes through the threaded through hole 110 and is screwed into the threaded hole.

[0045] In one embodiment of this utility model, the threaded through hole 110 on the positioning module 102 is a countersunk hole, with the upper diameter of the hole being larger than the diameter of the screw head. This ensures that the screw head is fully embedded in the hole after tightening and does not protrude from the surface of the positioning module 102, thus avoiding interference with the clamping and machining of the spiral groove parts. The threaded hole on the support module 100 is a blind hole, with a depth greater than the screw's screw insertion length, preventing the bottom of the screw from piercing through the support module 100. The screw is an internal hexagonal head screw with an internal hexagonal groove on the head for easy operation with an internal hexagonal wrench, preventing slippage during tightening. The screw material is consistent with that of the positioning module 102 and the support module 100, avoiding electrochemical corrosion caused by material differences. During assembly, align the screw with the countersunk hole of the positioning module 102 and screw it into the threaded hole of the support module 100 with a wrench until the screw head is flush with the bottom surface of the countersunk hole, completing the fixation. During disassembly, simply rotate the screw in the opposite direction with a wrench to remove it.

[0046] The countersunk hole design prevents the screw head from being exposed, avoiding collisions with spiral groove parts or machine tool cutting tools. This ensures ample machining space after the part is clamped, making it particularly suitable for machining the outer diameter or deep grooves of spiral groove parts, and preventing tool scratches on the screw or part. The large contact area of ​​the hex socket screw prevents slippage during tightening, ensuring even and sufficient clamping force and preventing misalignment of the positioning module 102 due to screw loosening. Furthermore, standardized hex wrenches are readily available and easy to use, reducing difficulties in disassembly and assembly due to incompatible tools. Screws made of the same material prevent electrochemical corrosion, ensuring smooth disassembly and assembly even after long-term use, without jamming. The blind hole design prevents cutting fluid or metal shavings from entering the threaded hole, avoiding thread damage and extending the service life of the threaded hole.

[0047] According to one embodiment of the present invention, the positioning module 102 is further provided with a chip removal groove 112 that communicates with the circular groove 104.

[0048] In one embodiment of this utility model, the chip removal groove 112 is a rectangular or trapezoidal groove, formed on the side or top surface of the positioning module 102. One end communicates with the inner wall of the circular groove 104, and the other end extends to the edge of the positioning module 102, forming a through chip removal channel. The width and depth of the chip removal groove 112 are adapted to the chip size during the machining of the spiral groove part, ensuring that the chips can pass smoothly without blocking the channel; the inner wall of the groove is smoothed and has no sharp edges to prevent chips from getting stuck in the groove. When the spiral groove part is machined in the circular groove 104, the generated chips are discharged from the positioning module 102 through the chip removal groove 112 under the flushing of the cutting fluid or the action of gravity, and fall into the chip removal system of the machine tool, without accumulating between the circular groove 104 and the part.

[0049] To prevent chip accumulation between the circular groove 104 and the spiral groove part, the chip removal groove 112 automatically removes chips in real time, reducing downtime for cleaning and improving continuous processing efficiency, which is especially suitable for continuous production of large batches of parts. This also prevents chips from rubbing against parts or modules within the circular groove 104, reducing surface wear and scratches on the inner wall of the positioning module 102, extending the service life of parts and equipment, and reducing replacement costs.

[0050] According to one embodiment of the present invention, there are multiple chip removal grooves 112, which are spaced apart along the length direction of the circular groove 104.

[0051] In one embodiment of this utility model, there are 35 chip removal grooves 112, evenly spaced along the length of the circular groove 104. Each chip removal groove 112 has the same structure and is perpendicularly connected to the inner wall of the circular groove 104. The spacing of the chip removal grooves 112 is adapted to the machining area of ​​the spiral groove part, ensuring that chips generated during machining can be discharged from the nearest chip removal groove 112, without any blind spots in chip removal. For example, when the middle and both ends of the part are machining areas, the chip removal grooves 112 at both ends and the middle can respectively discharge chips from the corresponding areas, preventing chips from accumulating in non-machining areas. Furthermore, the outlet of each chip removal groove 112 faces the direction of the machine tool's chip removal system, facilitating concentrated chip collection.

[0052] Multiple chip removal grooves 112 can simultaneously discharge chips from different areas, increasing chip removal speed several times compared to a single chip removal groove 112. Even in high-feed-rate machining scenarios, chip clogging can be avoided, ensuring continuous and stable machining. The spaced chip removal grooves 112 can cover the entire length of the circular groove 104, eliminating blind spots in chip removal and further ensuring part machining quality, avoiding machining defects caused by localized chip accumulation. For long spiral groove parts, multiple chip removal grooves 112 ensure smooth chip removal from different locations on the part, avoiding the problem of difficult chip removal at distant ends due to excessive part length, thus extending the device's adaptability to long parts.

[0053] According to one embodiment of the present invention, the cross-sectional profile of the circular groove 104 is an arc shape larger than a semicircle, so as to achieve a wrapping support for the spiral groove part.

[0054] In one embodiment of this utility model, the cross-section of the circular groove 104 is arc-shaped, with an arc angle greater than 180°. The inner diameter of the arc precisely matches the outer diameter of the spiral groove part to be processed, ensuring that the inner wall of the arc can tightly fit the outer circumference of the part after it is placed in. The inner wall of the circular groove 104 is polished, resulting in low surface roughness and preventing scratches on the surface of the part. The two ends of the arc are smoothly rounded, without sharp edges, to prevent scratches when the part is placed in. When the spiral groove part is placed in the circular groove 104, the arc, which is larger than a semicircle, can provide a wrapping support for the part from below and both sides, restricting the radial and axial movement of the part and retaining only the rotational freedom of the part around its own axis.

[0055] Compared to support structures smaller than or equal to semicircles, wrap-around supports offer a larger contact area, dispersing cutting forces on the parts and reducing deformation caused by concentrated stress. This is particularly suitable for thin-walled or high aspect ratio spiral groove parts, ensuring dimensional accuracy after machining. Wrap-around supports limit radial runout, preventing significant displacement even under radial cutting forces during machining, ensuring precise positioning of the spiral groove and reducing machining errors. The smooth, arc-shaped inner wall fits tightly against the part, preventing relative sliding between the part and the module during machining, reducing surface scratches, and preventing surface depressions caused by excessive localized stress, thus improving surface quality and meeting the high-precision requirements of medical tubing parts.

[0056] According to one embodiment of the present invention, the support module 100 includes a fixed base plate 114 and a raised boss 116 disposed on the fixed base plate 114, and the positioning module 102 is installed on the top surface of the raised boss 116.

[0057] In one embodiment of this utility model, the fixed base plate 114 of the support module 100 is a rectangular metal plate, the material of which is compatible with the machine tool table, possessing sufficient weight and rigidity to be stably placed on the machine tool table; the raised boss 116 is a rectangular or cylindrical metal block, integrally formed at the center of the top surface of the fixed base plate 114. The height of the boss is designed according to the stroke of the machine tool and the machining position requirements of the spiral groove part, ensuring that after the positioning module 102 is installed, the machining area of ​​the part can be accurately placed within the machining range of the tool. The top surface of the raised boss 116 is a precision-machined reference surface with high flatness, closely fitting the bottom surface of the positioning module 102 without gaps; the side of the boss is parallel to the side of the fixed base plate 114, ensuring that the positioning module 102 does not tilt after installation.

[0058] By adjusting the installation height of the positioning module 102 using the raised boss 116, the machine tool's parameters can be adjusted without modifying the raised boss itself. This allows for the adaptation to spiral groove parts of different diameters and machining positions, avoiding machining difficulties caused by incompatible part heights and improving the device's versatility. The raised boss 116 and the fixed base plate 114 are integrally formed, providing high overall rigidity and withstanding cutting forces and vibrations during machining. This prevents deformation of the support module 100, thus preventing the positioning module 102 from tilting and ensuring part machining accuracy. Simultaneously, the weight of the fixed base plate 114 increases the device's stability and reduces the impact of machine tool vibration. There is no need to customize dedicated machine tools or adjust the machine tool structure for parts of different heights; simply replacing the raised boss 116 with one of different heights suffices, reducing equipment investment costs and adapting to most existing CNC machining tools.

[0059] According to one embodiment of the present invention, the fixed base plate 114 is adapted to be fixed on the machine tool table by means of a T-block.

[0060] In one embodiment of this utility model, a T-slot along the length direction is provided on the fixed base plate 114, and the size of the T-slot is adapted to the T-block on the machine tool table. After the fixed base plate 114 is placed on the machine tool table, the T-block is slid into one end of the T-slot of the fixed base plate 114 until the end of the T-block abuts against the end of the slot; then, a bolt is passed through the center hole of the T-block and screwed into the threaded hole on the machine tool table, and the bolt is tightened so that the T-block presses upward against the inner wall of the T-slot of the fixed base plate 114, and the fixed base plate 114 is firmly fixed to the machine tool table by friction and pressure. There are two T-slots on the fixed base plate 114, which are symmetrically distributed along the width direction of the base plate to ensure that the base plate is evenly stressed after fixing and does not shift. During disassembly, the bolts are loosened, the T-block is slid out of the T-slot, and the fixed base plate 114 and the support module 100 can be removed.

[0061] The T-block and T-slot fit together to restrict the lateral and longitudinal movement of the fixed base plate 114. The tightening force of the bolts ensures a tight fit between the base plate and the machine tool table, preventing loosening even under high-speed machining or high-cutting-force scenarios, thus avoiding machining errors caused by the offset of the support module 100. T-block fixing is the standard fixing method for machine tool tables. This device, through T-block fixing, can be adapted to the table structure of most existing CNC machining tools without requiring machine tool modification, improving the device's versatility and reducing equipment adaptation costs. No additional drilling or welding is required on the machine tool table; fixing and disassembly can be completed solely with T-blocks and bolts. A single person can operate it quickly, facilitating the transfer of the device between different machine tools or adjustment of the installation position on the machine tool table, improving operational flexibility.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
