Description

Technical Field

[0001] This application relates to the technical field of heat pipe profile processing equipment, and more specifically, to a heat pipe profile outer circle processing and positioning equipment. Background Technology

[0002] In the current heat pipe profile manufacturing process, the fins on the profile need to be milled to make the cross-section of the heat pipe profile circular. However, due to the presence of the fins on the side wall of the profile, when fixing the profile, if the clamp is fixed on the fins, the fin size is difficult to control. At the same time, the fins are also the part that needs to be milled, which makes it difficult to control the processing accuracy and cannot guarantee the processing quality of the profile. The current method is to fix the clamp on the outer wall of the circular tube of the profile, avoiding the fin part. Since the fin range is difficult to control, the area that can provide support is not consistent. When clamping the profile, it is necessary to limit the axial and radial directions of the profile at the same time to prevent the profile from moving axially and deflecting around the axis. However, the existing clamps cannot adjust the clamping range, which makes it impossible to clamp the profile stably.

[0003] Therefore, a fixed positioning processing device for the outer circle machining of heat pipe profiles is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a heat pipe profile outer diameter machining and positioning device, comprising: a positioning rail, on which a lower support is fixedly mounted; a mounting frame, fixedly mounted on the positioning rail, with an upper positioning block provided on the mounting frame, the upper positioning block and the lower support being used to clamp and fix the profile; two sliding blocks slidably mounted on the lower support, supporting the lower end of the profile, with a sliding rack fixedly connected to each sliding block, and a guide groove for the sliding rack to be inserted into the lower support, the sliding rack being slidably positioned within the guide groove. A support plate is also provided on the lower support base, which is located between the two sliding blocks. The support plate is fixedly connected to a mounting post with one end inserted into the lower support base. The mounting post is provided with teeth. Two sets of adjustment components are provided in the lower support base. The distance between the two sliding blocks is adjusted by adjusting the adjustment components. The adjustment components include: a mounting groove opened in the lower support base, a third gear rotatably connected in the mounting groove, the third gear part being located in the guide groove and meshing with the sliding rack, and a first gear rotatably connected in the mounting groove and drivingly connected to the third gear, the first gear part being located in the mounting hole and meshing with the teeth on the mounting post.

[0006] The profile is clamped by the upper positioning block and the lower support base. At the same time, the two sliding blocks are set to support the wing edge of the profile, preventing the profile from rotating and causing processing defects. The third gear is set to adjust the distance between the two sliding blocks by rotating the third gear, so as to avoid difficulty in clamping due to different wing edge sizes.

[0007] Furthermore, a rotating shaft is rotatably installed in the mounting slot, and a second gear is fixedly connected to the rotating shaft. The second gear meshes with the first gear. A connecting sleeve is fixedly connected to the third gear and sleeved on the rotating shaft. A torsion spring is connected between the connecting sleeve and the rotating shaft, and the two ends of the torsion spring are fixedly connected to the connecting sleeve and the rotating shaft, respectively.

[0008] By means of the rotating shaft and connecting sleeve, when the support plate contacts the profile and moves downward, the mounting column drives the first gear to rotate, which in turn causes the second gear and the rotating shaft to rotate. The third gear then drives the sliding block to move, causing the two sliding blocks to move away from each other until they abut against the wing edge on the profile, thereby limiting the profile.

[0009] Furthermore, a positioning block is slidably connected in the mounting groove. The positioning block is inserted into the tooth groove of the third gear to limit the third gear. A deflection rod is provided in the mounting groove. The middle part of the deflection rod is rotatably set in the mounting groove by a pin. One end of the deflection rod extends into the mounting hole and is positioned at the lower end of the mounting hole. The mounting post abuts against the lower side of the positioning block.

[0010] With the positioning block in place, when the support plate moves to the bottom, the mounting post is inserted into the bottom of the mounting hole. This pushes the deflection rod to deflect, which in turn pushes the positioning block to move, so that the positioning block is embedded in the tooth groove of the third gear, limiting the third gear and preventing the profile from deflecting.

[0011] Furthermore, a connecting spring is provided between the positioning insert and the lower end wall of the mounting groove, with both ends of the connecting spring fixedly connected to the lower end wall of the positioning insert and the mounting groove, respectively.

[0012] Furthermore, a stop block is provided on the lower support base, and a guide rod that passes through the stop block and slides with the stop block is fixedly connected to the lower support base. A second screw is rotatably provided on the lower support base, and the second screw passes through the stop block and is threadedly connected to the stop block.

[0013] By setting up stops to limit the movement of the profile at both ends, the profile can be prevented from shifting.

[0014] Furthermore, a first screw is threaded onto the mounting bracket, and one end of the first screw is rotatably engaged with the upper positioning block.

[0015] When fixing the profile using the first screw, rotating the first screw clamps and fixes the profile to the upper positioning block and the lower support base.

[0016] Furthermore, the positioning track has multiple bolt holes arranged along its length, and the lower support base is installed on the positioning track by the cooperation of bolts with the bolt holes.

[0017] The beneficial effects of this application are as follows:

[0018] 1. The upper positioning block and lower support seat are used to clamp the profile. At the same time, the two sliding blocks are used to support the profile at the wing edge, preventing the profile from rotating and causing processing defects. The third gear is used to adjust the distance between the two sliding blocks by rotating the third gear, so as to avoid difficulty in clamping due to different wing edge sizes.

[0019] 2. Through the set rotating shaft and connecting sleeve, when the support plate contacts the profile and moves downward, it will drive the first gear to rotate through the mounting column, which in turn causes the second gear and rotating shaft to rotate. The third gear drives the sliding block to move, so that the two sliding blocks move away from each other until they abut against the wing edge on the profile, thereby limiting the profile.

[0020] 3. When fixing the profile using the first screw, rotating the first screw clamps and fixes the profile that is engaged with the upper positioning block and the lower support base. Attached Figure Description

[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figure 1-5A heat pipe profile outer diameter machining and positioning device includes: a positioning rail 10, a lower support base 11, a mounting bracket 12, an upper positioning block 14, a profile 15, a sliding block 19, a sliding rack 20, a support plate 22, and a mounting column 24. The positioning rail 10 has multiple bolt holes arranged along its length. The lower support base 11 is mounted on the positioning rail 10 by bolts engaging with the bolt holes. The mounting bracket 12 is fixedly mounted on the side of the positioning rail 10. A first screw 13 is threaded onto the mounting bracket 12. One end of the first screw 13 is rotatably mounted with an upper positioning block 14 located above the lower support base 11. The profile 15 is clamped and fixed between the lower support base 11 and the upper positioning block 14. By rotating the first screw 13, the upper positioning block 14 and the lower support base 11 move closer together, thereby pressing the profile 15 onto the lower support base 11. The lower end face of the upper positioning block 14 is shaped to mate with the profile 15.

[0037] Two sliding blocks 19, supporting the lower end of the profile 15, are slidably mounted on the lower support base 11. A sliding rack 20 is fixedly connected to each sliding block 19. A guide groove 21 is provided on the lower support base 11 for the sliding rack 20 to be inserted into, and the sliding rack 20 is slidably positioned within the guide groove 21. By sliding the rack 20, the two sliding blocks 19 are moved away from each other, adjusting the support range. A support plate 22 is also provided on the lower support base 11, located between the two sliding blocks 19. A mounting post 24, with teeth on its end, is fixedly connected to the support plate 22 and inserted into the lower support base 11. Receiving grooves 23 are provided on the two sliding blocks 19 for the support plate 22 to be inserted into. When it is necessary to fix the profile 15, the profile 15 is placed on the support plate 22, ensuring that the support plate 22 fits against the circumferential surface of the profile 15.

[0038] A mounting groove 26 is formed in the lower support 11. A third gear 30 is rotatably connected in the mounting groove 26. Part of the third gear 30 is located in the guide groove 21 and meshes with the sliding rack 20. A first gear 27 is rotatably connected in the mounting groove 26 and is driven by the third gear 30. Part of the first gear 27 is located in the mounting hole 25 and meshes with the teeth on the mounting post 24. A rotating shaft 29 is rotatably arranged in the mounting groove 26. A second gear 28 is fixedly connected to the rotating shaft 29 and meshes with the first gear 27. A connecting sleeve 31 is fixedly connected to the third gear 30 and sleeved on the rotating shaft 29. A torsion spring 32 is connected between the connecting sleeve 31 and the rotating shaft 29. The two ends of the torsion spring 32 are fixedly connected to the connecting sleeve 31 and the rotating shaft 29, respectively. When the upper positioning block 14 and the profile 15 are pressed onto the lower support base 11, the support plate 22 will move downward, causing the mounting column 24 to move downward, which will drive the two first gears 27 to rotate, and at the same time cause the second gear 28 and the third gear 30 to rotate, causing the two sliding blocks 19 to move away from each other, and then causing the sliding blocks 19 to abut against the edge of the wing of the profile 15, thus limiting the profile 15 in the circumferential direction.

[0039] A positioning block 33 is also slidably connected in the mounting groove 26. The positioning block 33 is inserted into the tooth groove of the third gear 30 to limit the third gear 30. A deflection rod 34 is provided in the mounting groove 26. The middle part of the deflection rod 34 is rotatably set in the mounting groove 26 by a pin. One end of the deflection rod 34 extends into the mounting hole 25 and is positioned at the lower end of the mounting hole 25. The mounting post 24 abuts against the lower side of the positioning block 33.

[0040] With the torsion spring 32 in place, when the two sliding blocks 19 abut against the wing edge, the sliding blocks 19 stop moving. When the support plate 22 moves into the receiving groove 23, the mounting post 24 abuts against one end of the mounting post 24, which causes the deflection rod 34 to deflect. One end of the deflection rod 34 pushes the positioning insert 33 to move, so that the positioning insert 33 is embedded in the tooth groove of the third gear 30 to limit the third gear 30. At this time, the sliding block 19 stops moving, thus preventing the profile 15 from shaking during the milling process.

[0041] A connecting spring 35 is provided between the positioning insert 33 and the lower end wall of the mounting groove 26. The two ends of the connecting spring 35 are fixedly connected to the lower end walls of the positioning insert 33 and 36, respectively. The positioning insert 33 is reset by the connecting spring 35.

[0042] A stop block 16 is provided on the lower support base 11. A guide rod 17 is fixedly connected to the lower support base 11, passing through the stop block 16 and slidingly engaging with the stop block 16. A second screw 18 is rotatably provided on the lower support base 11, passing through the stop block 16 and threadedly connected to the stop block 16. During positioning, to prevent the profile 15 from moving back and forth, the second screw 18 is rotated so that the stop block 16 abuts against one end of the profile 15, thereby positioning the profile 15.

[0043] Working process or usage method:

[0044] 1. During processing, the profile 15 is first placed on the support plate 22. By rotating the first screw 13, the upper positioning block 14 is pressed onto the profile 15, which causes the support plate 22 to move downward. Under the action of the mounting column 24, the first gear 27 rotates, which in turn drives the third gear 30 to rotate through the second gear 28. Under the action of the sliding rack 20, the two sliding blocks 19 move away from each other, and then the two sliding blocks 19 abut against the wing edge to limit the profile 15. After the sliding blocks 19 abut against the wing edge, the third gear 30 stops rotating. By rotating the second screw 18, the stop block 16 abuts against one end of the profile 15 to limit the axial movement.

[0045] 2. When the support plate 22 moves into the receiving groove 23, the lower end of the mounting column 24 pushes the deflection rod 34, which in turn causes the deflection rod 34 to deflect. One end of the deflection rod 34 will push the positioning block 33 to move and embed into the tooth groove of the third gear 30, limiting the third gear 30. At this time, the sliding block 19 no longer moves and performs circumferential fiber limiting, thereby completing the fixation of the profile 15.
