Abstract
Description
Technical Field
[0001] This application relates to the field of bar processing, and in particular to bar positioning molds. Background Technology
[0002] A bar is a solid material with a long, narrow shape, typically with a uniform cross-section, and its length is much longer than its diameter or other dimensions. It can be round, square, rectangular, or other special shapes. Bars can be made from a variety of materials, such as metals, plastics, and wood. Because the production process of bars is usually subject to strict process control, their material is uniform and their performance is stable. Many bar materials have high strength and stiffness, enabling them to withstand large loads. Bars can be cut, drilled, polished, and processed in various ways to create a variety of complex components and structures.
[0003] When processing bar stock, it needs to be fixed. However, because some bars are quite long and have different diameters, the current positioning molds are not stable enough in fixing the bars. This causes the bars to easily shift during processing, making it inconvenient for them to enter the processing machine, which is not conducive to improving the accuracy and efficiency of bar stock processing. Utility Model Content
[0004] To address the problem that current positioning molds are not stable enough in fixing the bar stock during use, this application provides a bar stock positioning mold.
[0005] The bar positioning mold provided in this application adopts the following technical solution:
[0006] The device includes a support frame and a bar stock. The support frame has a platform on which a transverse positioning mechanism and a longitudinal positioning mechanism are installed. The bar stock passes through the inner sides of the transverse positioning mechanism and the longitudinal positioning mechanism. The transverse positioning mechanism can restrict the two sides of the bar stock, and the longitudinal positioning mechanism can restrict the upper and lower parts of the bar stock.
[0007] By adopting the above technical solution, the side of the bar stock can be restricted by the lateral positioning mechanism to prevent the bar stock from shifting to the side, and the vertical positioning mechanism can prevent the bar stock from moving up and down, thereby improving the stability during processing.
[0008] Preferably, the lateral positioning mechanism includes two side fixing plates, which are connected by a limiting post. A movable plate is movably mounted on the limiting post, and a first friction pad is installed on the inner side of the movable plate. The bar is located between the two first friction pads.
[0009] By adopting the above technical solution, the two moving plates move inward synchronously, which can gradually push the first friction pad to contact the side of the bar, restrict the side of the bar, and prevent the bar from shifting to the side.
[0010] Preferably, an adjusting nut is installed in the middle of the two side fixing plates, and an adjusting screw is threaded to the inner side of the adjusting nut. One end of the adjusting screw is rotatably connected to the middle of the moving plate.
[0011] By adopting the above technical solution, rotating the adjusting screw, which cooperates with the adjusting nut, gradually pushes the moving plate inward, so that the first friction pad and the bar can be put into contact.
[0012] Preferably, the longitudinal positioning mechanism includes a stud, an adjusting plate is provided on the stud, the stud passes through the adjusting plate, and the diameter of the stud is smaller than the diameter of the through-hole. There are two adjusting plates, which are arranged vertically opposite each other.
[0013] By adopting the above technical solution, the upper adjustment plate is moved downwards, so that the inner wall of the groove on the upper adjustment plate fits against the upper part of the bar stock, which facilitates the restriction of the bar stock.
[0014] Preferably, a second friction pad is installed on the inner side of the two adjustment plates, a groove is formed in the middle of the adjustment plate, the bar is located inside the groove between the two adjustment plates, and a push nut is threaded onto the stud, the push nut abutting against the surface of the adjustment plate.
[0015] By adopting the above technical solution, the lower part of the bar stock is located on the lower adjustment plate. Then, the push nut is rotated to move the push nut downwards and make it fit against the surface of the upper adjustment plate, thus restricting the upper adjustment plate. By restricting the bar stock with the upper and lower adjustment plates, longitudinal movement of the bar stock can be prevented during processing.
[0016] Preferably, a movable rail is installed on the table surface, and a movable component is slidably connected to the movable rail. The movable component is connected to the lower part of the transverse positioning mechanism. Multiple limiting holes are opened on the movable rail, and a plug-in post is installed on the movable component. The lower part of the plug-in post is inserted into the interior of two of the limiting holes.
[0017] By adopting the above technical solution, the plug-in pin is removed from the inside of the limiting hole, and then the two side fixing plates are moved synchronously to the left and right. At this time, the entire lateral positioning mechanism can be moved horizontally to adjust the distance between the lateral positioning mechanism and the longitudinal positioning mechanism.
[0018] Preferably, a telescopic screw is installed at the lower part of the support frame, a pad is installed at the lower end of the telescopic screw, an extension plate is installed on the pad, and a fastening stud is installed on the extension plate.
[0019] By adopting the above technical solution, the extension plate supports the whole structure, and the extension plate is fixed to the ground by fastening studs, thereby improving the overall stability.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. This application moves the upper adjustment plate downwards so that the inner wall of the groove on the upper adjustment plate fits against the upper part of the bar stock, and the second friction pad contacts the bar stock, thereby increasing the friction of the contact part. The lower part of the bar stock is located on the lower adjustment plate. Then, the push nut is rotated so that the push nut moves downwards and fits against the surface of the upper adjustment plate, thereby restricting the upper adjustment plate. By restricting the bar stock with the upper and lower adjustment plates, longitudinal movement of the bar stock during processing can be prevented.
[0022] 2. This application utilizes the method of rotating the adjusting screw, which, in conjunction with the adjusting nut, gradually pushes the moving plate inward. By having both moving plates move inward synchronously, the first friction pad can be gradually pushed into contact with the side of the bar, thus restricting the side of the bar and preventing it from shifting to the side.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0029] This application discloses a bar positioning mold, including a support frame 1 and a bar 8. The support frame 1 is provided with a table 2, and a transverse positioning mechanism 3 and a longitudinal positioning mechanism 9 are installed on the table 2. The transverse positioning mechanism 3 can restrict the side of the bar 8 to prevent the bar 8 from shifting to the side. The longitudinal positioning mechanism 9 can prevent the bar 8 from moving up and down, thereby improving the stability during processing. The bar 8 passes through the inner sides of the transverse positioning mechanism 3 and the longitudinal positioning mechanism 9. The transverse positioning mechanism 3 can restrict the two sides of the bar 8, and the longitudinal positioning mechanism 9 can restrict the upper and lower parts of the bar 8, thereby preventing the bar 8 from moving during processing.
[0030] Please refer to Figure 2 The transverse positioning mechanism 3 includes two side fixing plates 31, which are connected by a limiting post 32. A movable plate 33 is movably mounted on the limiting post 32. A first friction pad 34 is installed on the inner side of the movable plate 33. The bar stock 8 is located between the two first friction pads 34. An adjusting nut 35 is installed in the middle of the two side fixing plates 31. An adjusting screw 36 is threadedly connected to the inner side of the adjusting nut 35. One end of the adjusting screw 36 is rotatably connected to the middle of the movable plate 33. By rotating the adjusting screw 36, the adjusting screw 36, in cooperation with the adjusting nut 35, gradually pushes the movable plate 33 to move inward. By moving the two movable plates 33 inward synchronously, the first friction pads 34 can be gradually pushed to contact the side of the bar stock 8, thus restricting the side of the bar stock 8 and preventing the bar stock 8 from shifting to the side.
[0031] Please refer to Figure 1 and Figure 3 The longitudinal positioning mechanism 9 includes a stud 91, on which an adjusting plate 92 is mounted. The stud 91 passes through the adjusting plate 92, and the diameter of the stud 91 is smaller than the diameter of the penetration. There are two adjusting plates 92, arranged vertically opposite each other. A second friction pad 93 is installed on the inner side of the two adjusting plates 92. A groove 94 is formed in the middle of the adjusting plate 92. The bar stock 8 is located inside the groove 94 between the two adjusting plates 92. A push nut 95 is threaded onto the stud 91 and abuts against the surface of the adjusting plate 92. The upper adjusting plate 92 is moved downwards, so that the inner wall of the groove 94 on the upper adjusting plate 92 fits against the upper part of the bar stock 8, and the second friction pad 93 contacts the bar stock 8, increasing the friction of the contact part. The lower part of the bar stock 8 is located on the lower adjusting plate 92. Then, the push nut 95 is rotated, so that the push nut 95 moves downwards and fits against the surface of the upper adjusting plate 92, thus restricting the upper adjusting plate 92. By restricting the bar stock with the upper and lower adjusting plates 92, longitudinal movement of the bar stock 8 can be prevented during processing.
[0032] Please refer to Figure 1 and Figure 2A movable rail 4 is installed on the table 2. A movable part 5 is slidably connected to the movable rail 4. The movable part 5 is connected to the lower part of the transverse positioning mechanism 3. Multiple limiting holes 6 are opened on the movable rail 4. A plug-in post 7 is installed on the movable part 5. The lower part of the plug-in post 7 is inserted into the interior of two of the limiting holes 6. The plug-in post 7 is taken out from the interior of the limiting holes 6, and then the two side fixing plates 31 are moved to the left and right simultaneously. At this time, the entire transverse positioning mechanism 3 can be moved horizontally to adjust the distance between the transverse positioning mechanism 3 and the longitudinal positioning mechanism 9.
[0033] Please refer to Figure 1 and Figure 4 The lower part of the support frame 1 is equipped with a telescopic screw 10, the lower end of the telescopic screw 10 is equipped with a pad 11, the pad 11 is equipped with an extension plate 12, and the extension plate 12 is equipped with a fastening stud 13. The extension plate 12 supports the whole, and the fastening stud 13 fixes the extension plate 12 to the ground, thereby improving the overall stability.
[0034] The implementation principle of the bar positioning mold in this application embodiment is as follows: In actual use, the bar 8 is first passed through the interior of the transverse positioning mechanism 3 and the longitudinal positioning mechanism 9. At this time, the upper adjustment plate 92 is moved downward so that the inner wall of the groove 94 on the upper adjustment plate 92 is attached to the upper part of the bar 8, and the second friction pad 93 is in contact with the bar 8 to increase the friction of the contact part. The lower part of the bar 8 is located on the lower adjustment plate 92. Then, the push nut 95 is rotated so that the push nut 95 moves downward and is attached to the surface of the upper adjustment plate 92 to restrict the upper adjustment plate 92. By restricting the bar with the upper and lower adjustment plates 92, the longitudinal movement of the bar 8 can be prevented during processing. At this time, the adjusting screw 36 is rotated. The adjusting screw 36, in cooperation with the adjusting nut 35, gradually pushes the moving plate 33 to move inward. By the two moving plates 33 moving inward synchronously, the first friction pad 34 can be gradually pushed to contact the side of the bar 8 to restrict the side of the bar 8 and prevent the bar 8 from shifting to the side.
[0035] Before use, the plug pin 7 can be removed from the inside of the limiting hole 6, and then the two side fixing plates 31 can be moved to the left and right simultaneously. At this time, the entire horizontal positioning mechanism 3 can be moved horizontally to adjust the distance between the horizontal positioning mechanism 3 and the vertical positioning mechanism 9. After the adjustment is completed, the plug pin 7 can be inserted into the corresponding limiting hole 6 again to fix the horizontal positioning mechanism 3.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
