Description

Technical Field

[0001] This application relates to the field of metal tube processing technology, and in particular to a metal surface treatment fixture. Background Technology

[0002] In industrial production, metal pipes are widely used in machinery manufacturing, construction engineering, petrochemicals, and many other fields due to their excellent mechanical properties and structural stability. To ensure the reliability of metal pipe connections, corrosion resistance, and the quality of subsequent processing (such as painting and plating), surface treatment (such as rust removal, grinding, and polishing) is an essential process. The efficiency and quality of metal surface treatment largely depend on the performance of the fixtures. The fixtures must be able to stably hold the metal pipes and also coordinate with the processing steps to allow for proper movement of the metal pipes, ensuring uniform and efficient surface treatment.

[0003] In existing technologies, some metal tube surface treatment fixtures can only perform a fixed clamping function, that is, they firmly fix the metal tube in a specific position through a mechanical structure. This fixed clamping method requires manual rotation of the metal tube or movement of the grinding tool to complete the overall treatment of the outer circumference. This not only increases the intensity of manual operation, but also easily leads to poor surface treatment accuracy due to uneven rotation angles and inconsistent contact between the grinding tool and the metal tube, resulting in local over-grinding or under-grinding. At the same time, in existing metal tube surface treatment fixtures, clamping and grinding are usually separated. That is, the clamping device is only responsible for fixing the metal tube, and the grinding operation must be completed by a separate grinding mechanism. This separate structure not only makes the overall equipment bulky and complex in layout, but also causes inaccurate grinding position due to positioning deviation between the clamping device and the grinding mechanism, affecting the processing quality. Moreover, when adjusting the grinding parameters, the clamping device and the grinding mechanism must be operated separately, making it difficult to quickly adapt to the surface treatment requirements of different metal tubes and reducing processing efficiency.

[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this application is to provide a metal surface treatment fixture that overcomes, at least to some extent, one or more problems caused by the limitations and defects of related technologies.

[0007] To achieve the objectives of this application, the following technical solution is provided:

[0008] This application provides a metal surface treatment fixture, comprising:

[0009] The support assembly has a transmission mechanism at the top for placing the metal tube to be processed on the top surface and providing directional friction force to the bottom surface of the metal tube to be processed upon startup;

[0010] The clamping assembly includes a height adjusting member and a clamping member; the clamping member is fixedly connected to the height adjusting member, and has an opening on its bottom surface for covering the metal tube to be processed from top to bottom and contacting the surface of the metal tube to be processed, so as to polish the surface of the metal tube to be processed when it rotates; the height adjusting member is fixedly connected to the transmission mechanism for adjusting the longitudinal position of the clamping member.

[0011] The directional friction force is directed toward the clamping surface of the clamping member, and when the transmission mechanism is started, it drives the metal tube to be processed to rotate in the clamping member.

[0012] In one possible implementation, the support assembly further includes a first support member; the top end of the first support member is fixedly connected to the bottom surface of the transmission mechanism to provide support for the transmission mechanism.

[0013] In one possible implementation, the height adjustment component includes a support frame and a first screw; the bottom end of the support frame is fixedly connected to the transmission mechanism, and the top end is rotatably connected to the bottom end of the first screw.

[0014] In one possible implementation, the clamping member includes an adjusting block, a connecting frame, and two grinding stone limiting plates; the adjusting block has an internal threaded through hole that engages with the first screw threaded connection; the top end of the connecting frame is fixedly connected to the adjusting block, and the bottom end is fixedly connected to the two grinding stone limiting plates; the two grinding stone limiting plates clamp the metal tube to be processed.

[0015] In one possible implementation, the clamping member further includes a second screw, and the two grinding stone limiting plates are fixedly connected to the connecting frame through the second screw; the second screw is fixedly connected to the bottom end of the connecting frame, one end of the second screw is fixedly connected to one of the grinding stone limiting plates, and the other end slides through one of the grinding stone limiting plates and is limited by a nut.

[0016] In one possible implementation, the metal surface treatment fixture further includes a base, and there are multiple support components and clamping components, with the support components slidably disposed on the top surface of the base.

[0017] In one possible implementation, the bottom end of the first support member has a slider, the base has a sliding track, and the slider is rotatably disposed in the sliding track.

[0018] In one possible implementation, the first screw has a rotating handle at its top.

[0019] In one possible implementation, the height adjustment component further includes a limiting frame fixed to the transmission mechanism, and the connecting frame has a protrusion on the side near the limiting frame, the protrusion being slidably sleeved on the limiting frame.

[0020] In one possible implementation, the transmission mechanism includes a transmission mechanism body and a conveyor belt, wherein the bottom end of the support frame and the bottom end of the limiting frame are both fixedly connected to the transmission mechanism body on both sides of the conveyor belt.

[0021] The technical solution provided in this application may include the following beneficial effects:

[0022] This metal surface treatment fixture can drive the metal tube to be processed to rotate by providing directional friction force through a transmission mechanism. The clamping component covers and contacts the surface of the metal tube from above, and grinding is completed during the rotation of the metal tube. It can achieve comprehensive processing without manual rotation, which solves the problems of fixed clamping requiring manual rotation and poor processing accuracy in the prior art. Furthermore, by integrating the clamping and grinding functions into the clamping component, it avoids the problems of complex equipment layout and positioning deviation caused by the separation of clamping and grinding in the traditional method. At the same time, by using the height adjustment component to adjust the longitudinal position of the clamping component, it can flexibly adapt to metal tubes of different diameters, solving the problems of cumbersome adjustment and poor adaptability of traditional fixtures, and improving processing efficiency and quality.

[0030] 400. Metal tubes to be processed. Detailed Implementation

[0031] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0032] Furthermore, the accompanying drawings are merely illustrative of this application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.

[0033] This example embodiment first provides a metal surface treatment fixture. (See reference...) Figure 1-3 As shown, the metal surface treatment fixture includes a support assembly 200 and a clamping assembly 300.

[0034] The support component 200 has a transmission mechanism 220 at the top, which is used to place the metal tube 400 to be processed on the top surface and to provide directional friction force to the bottom surface of the metal tube 400 to be processed when it is started.

[0035] The clamping assembly 300 includes a height adjusting member 310 and a clamping member 320; the clamping member 320 is fixedly connected to the height adjusting member 310, and has an opening on its bottom surface for covering the metal tube 400 to be processed from top to bottom and contacting the surface of the metal tube 400 to be processed, and polishing its surface when the metal tube 400 to be processed rotates; the height adjusting member 310 is fixedly connected to the transmission mechanism 220 for adjusting the longitudinal position of the clamping member 320.

[0036] The directional friction force is directed toward the clamping surface of the clamping member 320, and when the transmission mechanism 220 is started, it drives the metal tube 400 to be processed to rotate in the clamping member 320.

[0037] The metal surface treatment fixture described above can drive the metal tube 400 to be processed to rotate by the directional friction force provided by the transmission mechanism 220. At the same time, the longitudinal position of the clamping member 320 can be adjusted by the height adjustment member 310 so that the clamping member 320 covers and contacts the surface of the metal tube 400 to be processed from top to bottom. During the rotation of the metal tube, the surface of the metal tube is polished, thereby efficiently completing the surface treatment operation of the metal tube.

[0038] In one embodiment, the support assembly 200 further includes a first support member 210; the top end of the first support member 210 is fixedly connected to the bottom surface of the transmission mechanism 220, and is used to provide support for the transmission mechanism 220.

[0039] It should be noted that the first support member 210 can be made of metal, and its height can be set according to the actual use scenario. Through the fixed connection with the transmission mechanism 220, it can effectively distribute the weight of the metal tube 400 to be processed borne by the transmission mechanism 220, avoid deformation of the transmission mechanism 220 due to long-term stress, and ensure the service life and operational stability of the transmission mechanism 220.

[0040] In one embodiment, the height adjustment member 310 includes a support frame 311 and a first screw 312; the bottom end of the support frame 311 is fixedly connected to the transmission mechanism 220, and the top end is rotatably connected to the bottom end of the first screw 312.

[0041] It should be noted that the structure of the support frame 311 can be designed as a frame or column to reduce the overall weight while ensuring the support strength; the thread accuracy of the first screw 312 must meet the design requirements to ensure smooth engagement with the thread of the adjusting block 321, thereby achieving precise adjustment of the longitudinal position of the clamping part 320 to meet the grinding needs of metal tubes 400 of different diameters to be processed.

[0042] Optionally, the first screw 312 has a rotating handle 330 at its top.

[0043] It should be noted that the handle 330 can be wrapped with non-slip materials such as rubber to increase the friction between the hand and the handle and prevent slippage during rotation; the handle 330 can be set perpendicular to the axis of the first screw 312.

[0044] In one embodiment, the clamping member 320 includes an adjusting block 321, a connecting frame 322, and two grinding stone limiting plates 324; the adjusting block 321 has an internal threaded through hole that is threadedly engaged with the first screw 312; the top end of the connecting frame 322 is fixedly connected to the adjusting block 321, and the bottom end is fixedly connected to the two grinding stone limiting plates 324; the two grinding stone limiting plates 324 clamp the metal tube 400 to be processed.

[0045] Optionally, the grinding stone limiting plate 324 can be selected with different mesh sizes to achieve different roughness requirements.

[0046] Understandably, the internal threaded through hole of the adjusting block 321 must match the external thread of the first screw 312 to ensure the transmission efficiency and stability between the two; the connecting bracket 322 can be fixed to the adjusting block 321 and the grinding stone limiting plate 324 by welding or bolting to ensure the connection strength and prevent loosening due to vibration during the grinding process; the opposite surfaces of the two grinding stone limiting plates 324 can be set to an arc shape that matches the outer circle of the metal tube 400 to be processed, so as to increase the contact area with the surface of the metal tube 400 and improve the grinding effect.

[0047] Furthermore, the clamping member 320 also includes a second screw 323, and the two grinding stone limiting plates 324 are fixedly connected to the connecting frame 322 through the second screw 323; the second screw 323 is fixedly connected to the bottom end of the connecting frame 322, one end of the second screw 323 is fixedly connected to one of the grinding stone limiting plates 324, and the other end slides through one of the grinding stone limiting plates 324 and is limited by a nut.

[0048] Understandably, the surface of the second screw 323 can be set with scales to allow operators to intuitively understand the distance between the two grinding stone limit plates 324 and achieve precise adjustment; the thread fit between the nut and the second screw 323 must be tight to prevent the nut from loosening due to vibration during grinding and to ensure that the clamping force of the grinding stone limit plate 324 on the metal tube 400 to be processed is stable.

[0049] In one embodiment, the metal surface treatment fixture further includes a base 100, and there are multiple support components 200 and clamping components 300, with the support components 200 slidably disposed on the top surface of the base 100.

[0050] It should be noted that the base 100 can be made of a material with good rigidity, such as cast iron, to ensure the stability of its overall structure; the layout of multiple support components 200 and clamping components 300 can be set according to production needs, and can work independently or in concert to flexibly adapt to different processing batches; the sliding setting of the support components 200 can adopt a high-precision structure such as linear guide rails to ensure the smoothness and positional accuracy of the adjustment process.

[0051] Furthermore, the bottom end of the first support member 210 has a sliding member 230, and the base 100 has a sliding track 110, with the sliding member 230 rotatably disposed in the sliding track 110.

[0052] It should be noted that the sliding component 230 can adopt a roller or ball bearing structure, and its surface can be hardened to improve wear resistance; the cross-sectional shape of the sliding track 110 can be designed as T-shaped or dovetail-shaped to match the sliding component 230 and prevent the sliding component 230 from disengaging from the track 110 during movement; grease can be applied to the inner side of the track 110 to reduce frictional wear between the sliding component 230 and the track 110 and extend the service life of the components. A sliding locking device is also provided to lock the first support component 210 when it slides to the appropriate position.

[0053] In one embodiment, the height adjustment member 310 further includes a limiting frame 313, which is fixed on the transmission mechanism 220. The connecting frame 322 has a protrusion on the side near the limiting frame 313, and the protrusion is slidably sleeved on the limiting frame.

[0054] It should be noted that the limiting frame 313 can be made of square steel pipe or solid rod, and its length must be greater than the maximum adjustment stroke of the clamping member 320 to ensure that the protrusion is always fitted on the limiting frame 313 during the entire process of the clamping member 320 moving up and down. The fit clearance between the protrusion and the limiting frame 313 must be reasonably controlled to ensure that the protrusion can slide smoothly and effectively limit the lateral displacement of the connecting frame 322, thereby improving the operational stability of the clamping member 320.

[0055] In one embodiment, the transmission mechanism 220 includes a transmission mechanism body 221 and a conveyor belt 222, and the bottom ends of the support frame 311 and the limiting frame 313 are fixedly connected to the transmission mechanism body 221 on both sides of the conveyor belt 222.

[0056] It should be noted that the conveyor belt 222 can be a rubber belt or a metal mesh belt, and its surface can be provided with anti-slip texture to enhance the friction with the bottom surface of the metal tube 400 to be processed, so as to ensure that the metal tube 400 can rotate stably; the main body 221 of the transmission mechanism can be equipped with a drive motor and transmission roller to provide power for the operation of the conveyor belt 222, and its fixed connection with the support frame 311 and the limit frame 313 can be fastened with bolts, which facilitates disassembly and maintenance in the later stage.

[0057] In one embodiment, a metal tube limiting member is also provided at one end of the base 100. The metal tube is limited without affecting the rotation of the metal tube 400 to be processed, so as to prevent the metal tube from falling off due to rotation. At the same time, the metal tube can be polished and rusted as a whole by sliding support assembly 200.

[0058] Working principle:

[0059] The metal tube 400 to be processed is placed on the conveyor belt 222 of the transmission mechanism 220 of the support assembly 200. According to the diameter of the metal tube 400 to be processed, the height adjustment component 310 is adjusted by rotating the rotating handle 330 at the top of the first screw 312: the first screw 312 is threadedly engaged with the adjusting block 321. When rotating, it drives the adjusting block 321 and the connecting frame 322 to move longitudinally, thereby adjusting the height of the clamping component 320, so that the two grinding stone limiting plates 324 cover the metal tube 400 to be processed from top to bottom and contact its surface to form a stable clamping. At this time, the protrusion of the connecting frame 322 slides along the limiting frame 313. The limiting frame 313 restricts the lateral displacement of the connecting frame 322, ensuring the stability of the longitudinal adjustment of the clamping component 320.

[0060] If there are slight differences in the diameter of the metal tube 400 to be processed, the distance between the two grinding stone limiting plates 324 can be adjusted by the second screw 323: the grinding stone limiting plate 324, which is slidably inserted on the second screw 323, can move along the screw. After adjusting to the appropriate position, it can be locked with a nut to ensure the fit between the grinding stone limiting plate 324 and the surface of the metal tube 400 to be processed.

[0061] After the transmission mechanism 220 is started, the main body 221 of the transmission mechanism drives the conveyor belt 222 to operate. The surface of the conveyor belt 222 contacts the bottom surface of the metal tube 400 to be processed and generates directional friction force, which drives the metal tube 400 to be processed to rotate between the two grinding stone limiting plates 324. During the rotation, the surface of the metal tube 400 to be processed continuously rubs against the grinding stone limiting plates 324 to achieve surface grinding treatment.

[0062] Depending on the length of the metal tube 400 to be processed, multiple support components 200 and clamping components 300 can be added to ensure the stability of the metal tube 400. Meanwhile, the clamping members 320 located on both sides of the first screw 312 can process two metal tubes simultaneously.

[0063] Throughout the process, the metal tube 400 to be processed can be polished and rusted by manual assistance in pushing it, or the entire tube can be rusted by manual assistance through the sliding support component 200.
