Description

Technical Field

[0001] This utility model relates to the field of metal processing, specifically to a quick-installable needle roller guide post assembly. Background Technology

[0002] Existing needle roller guides have significant shortcomings in installation and maintenance. They are mostly directly fixed to the equipment through bolt holes on the bottom outer wall. When the guide column needs to be replaced due to wear or damage, all bolts connecting the guide column to the equipment must be removed first, resulting in a cumbersome and time-consuming overall disassembly process.

[0003] Therefore, this utility model provides a quick-installation needle roller guide post assembly. The quick-installation device quickly connects the threaded rod of the fixed seat with the threaded hole of the post body, and with the limiting effect of the retaining spring in the limiting groove, a stable assembly of the post body and the base is achieved. When replacing, the post body can be replaced simply by loosening and unloosening the retaining spring 24 with retaining spring pliers, without the need to completely disassemble the equipment connection structure, thus meeting the needs of the metal processing industry for quick installation of needle roller guide posts. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a quick-installation needle roller guide post assembly, comprising: a column body, wherein a threaded hole is formed on the inner wall of the bottom end of the column body, and a quick-installation device is provided on the outer wall of the bottom end of the column body; replacement limiting devices are symmetrically provided on both outer walls of the quick-installation device; the quick-installation device includes a base, wherein a storage groove is formed on the inner wall of the base, a limiting groove is formed on the inner wall of the storage groove, a fixing seat is slidably connected to the inner wall of the storage groove, and ear wedges are symmetrically provided on the outer wall of the fixing seat. A threaded rod is fixedly connected to the outer wall of the fixed base, and a snap ring is engaged with the inner wall of the limiting groove. Threaded holes and limiting holes are symmetrically opened on the outer wall of the base, and these holes are arranged in a linear array along the outer wall of the base. In use, this component adopts a combination design of a quick-installation device and a replacement limiting device. During the initial installation stage, the mounting base of the replacement limiting device must first be fixed to the designated position of the target device with bolts through the symmetrically opened mounting holes on its outer wall. This step is a one-time operation, and the mounting base does not need to be disassembled when replacing the guide post subsequently.

[0005] Preferably, the inner wall of the threaded hole at the bottom of the column is threaded to the inner wall of the threaded rod, and the outer wall of the snap ring is in contact with the outer wall of the fixed seat. The outer diameter of the snap ring is larger than the outer diameter of the fixed seat, and the inner diameter of the snap ring is smaller than the inner diameter of the fixed seat. After the pre-fixing of the mounting seat is completed, the column and the quick-assembly device are assembled. The threaded hole on the inner wall at the bottom of the column is aligned with the threaded rod on the outer wall of the fixed seat in the quick-assembly device and tightened to achieve a rigid connection between the two. Then, the assembled fixed seat is slid into the storage groove of the base until it fits against the bottom of the storage groove. Then, the snap ring is snapped into the limiting groove of the base. Since the outer diameter of the snap ring is larger than the outer diameter of the fixed seat and the inner wall is smaller than the inner diameter of the fixed seat, it can abut against the outer wall of the fixed seat to prevent it from axially loosening in the storage groove. The ear wedges symmetrically arranged on the outer wall of the fixed seat abut against the storage groove to prevent the fixed seat from rotating circumferentially, thereby completing the integrated assembly of the column and the quick-assembly device.

[0006] Preferably, the replacement limiting device includes a mounting base. The outer wall of the mounting base has symmetrically formed mounting holes, and the side wall of the mounting base has a sliding groove. Both the sliding groove and the inner wall of the mounting base have limiting holes. The inner wall of the limiting hole is slidably connected to a wedge. The mounting holes and limiting holes are distributed in a linear array along the outer wall of the mounting base. Next, the quick-installation device with the column is connected to the equipment. The base of the quick-installation device is slid into the corresponding position along the sliding groove on the side wall of the mounting base. Then, the wedge is slid into the limiting hole of the mounting base aligned with the base. The internal hex bolts symmetrically connected to the inner wall of the wedge are tightened with a tool so that the end of the bolt is screwed into the threaded hole on the outer wall of the base. Finally, the quick-installation device is fixed to the equipment through the mounting base. The entire installation process does not require repeated alignment of the bolt holes.

[0007] Preferably, the inner wall of the wedge is symmetrically threaded with hexagonal bolts, and the inner wall of the mounting base's groove is fixedly connected to the threaded hole on the outer wall of the base via the hexagonal bolts on the outer wall of the wedge. When the column needs to be replaced with a different size for work purposes, there is no need to disassemble the entire device. First, use an Allen wrench to loosen the hexagonal bolts on the wedge counterclockwise so that the bolts are disengaged from the threaded hole of the base. Then, pull the wedge out of the limiting hole to release the quick-release device from the mounting base. Subsequently, slide the base with the old column along the groove of the mounting base. If only the column is damaged, remove the snap ring with snap ring pliers, loosen the old column to disengage it from the threaded rod of the fixing base, and the fixing base, base, and other undamaged parts do not need to be disassembled and can be reused. Finally, tighten the threaded hole at the bottom of the new column to the threaded rod of the fixing base, and then reset the snap ring to complete the replacement. The entire process does not require disassembling the connection structure between the mounting base and the equipment.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a quick-installation device, utilizes the quick threaded connection between the threaded rod of the fixed base and the threaded hole at the bottom of the column, and with the limiting of the retaining spring in the limiting groove, to complete the stable assembly of the column and the base. When replacing, only the retaining spring needs to be loosened and removed with retaining spring pliers to replace the column, without disassembling the entire equipment.

[0009] 2. By setting a replacement limiting device, when the column needs to be replaced with a different size due to work, there is no need to disassemble the mounting base pre-fixed on the equipment. Only the internal hex bolts of the wedge need to be loosened and the wedge needs to be pulled out. The base with the old column can be slid out along the slide groove. After replacing the old column, the undamaged parts such as the base and fixing seat can be reused. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0013] Example: Please see Figure 1 - Figure 5This utility model provides a technical solution: a quick-installable needle roller guide post assembly, comprising: a column 1, a threaded hole 25 on the inner wall of the bottom end of the column 1, a quick-installation device 2 on the outer wall of the bottom end of the column 1, and replacement limiting devices 3 symmetrically provided on the outer walls of both sides of the quick-installation device 2; the quick-installation device 2 includes a base 20, a storage groove 21 on the inner wall of the base 20, a limiting groove 22 on the inner wall of the storage groove 21, a fixed seat 23 slidably connected to the inner wall of the storage groove 21, ear wedges symmetrically provided on the outer wall of the fixed seat 23, a threaded rod fixedly connected to the outer wall of the fixed seat 23, a retaining spring 24 snapped into the inner wall of the limiting groove 22, and threaded holes 25 and limiting holes 33 symmetrically provided on the outer wall of the base 20, the threaded holes 25 and limiting holes 33 being linearly arrayed along the outer wall of the base 20.

[0014] The inner wall of the threaded hole 25 at the bottom of the column 1 is threaded to the inner wall of the threaded rod. The outer wall of the snap ring 24 is in contact with the outer wall of the fixed seat 23. The outer diameter of the snap ring 24 is larger than the outer diameter of the fixed seat 23, and the inner diameter of the snap ring 24 is smaller than the inner diameter of the fixed seat 23.

[0015] The replacement limiting device 3 includes a mounting base 30. The outer wall of the mounting base 30 is symmetrically provided with mounting holes 31. The side wall of the mounting base 30 is provided with a sliding groove 32. The sliding groove 32 and the inner wall of the mounting base 30 are both provided with limiting holes 33. The inner wall of the limiting hole 33 is slidably connected with a wedge 34. The mounting holes 31 and the limiting holes 33 are distributed in a linear array along the outer wall of the mounting base 30.

[0016] The inner wall of the wedge 34 is symmetrically threaded with hexagon socket bolts, and the inner wall of the groove 32 of the mounting base 30 is fixedly connected to the threaded hole 25 on the outer wall of the base 20 through the hexagon socket bolts on the outer wall of the wedge 34.

[0017] Working principle: When in use, this component adopts a combination design of quick-installation device 2 and replacement limiting device 3. In the initial installation stage, the mounting base 30 of the replacement limiting device 3 must first be fixed to the designated position of the target equipment with bolts through the mounting holes 31 symmetrically opened on its outer wall. This step is a one-time operation, and the mounting base 30 does not need to be disassembled when the guide post is replaced in the future.

[0018] After the mounting base 30 is pre-fixed, the column 1 and the quick-installation device 2 are assembled. The threaded hole 25 on the inner wall of the bottom end of the column 1 is aligned with the threaded rod on the outer wall of the fixed base 23 in the quick-installation device 2 and tightened to achieve a rigid connection between the two. Then, the assembled fixed base 23 is slid into the storage groove 21 of the base 20 until it fits against the bottom of the storage groove 21. Then, the retaining spring 24 is snapped into the limiting groove 22 of the base 20. Since the outer diameter of the retaining spring 24 is larger than the outer diameter of the fixed base 23 and the inner wall is smaller than the inner diameter of the fixed base 23, it can abut against the outer wall of the fixed base 23 to prevent it from axially loosening in the storage groove 21. The ear wedges symmetrically arranged on the outer wall of the fixed base 23 abut against the storage groove 21 to prevent the fixed base 23 from rotating circumferentially, thereby completing the integrated assembly of the column 1 and the quick-installation device 2.

[0019] Next, connect the quick-installation device 2 with column 1 to the equipment. Slide the base 20 of the quick-installation device 2 into the corresponding position along the slide groove 32 on the side wall of the mounting base 30. Then slide the wedge 34 into the limiting hole 33 that is aligned with the mounting base 30 and the base 20. Tighten the internal hex bolts that are symmetrically connected to the inner wall of the wedge 34 with a tool, so that the end of the bolt is screwed into the threaded hole 25 on the outer wall of the base 20. Finally, the quick-installation device 2 is fixed to the equipment through the mounting base 30. The entire installation process does not require repeated alignment of the bolt holes.

[0020] When the column 1 needs to be replaced with a different size for work purposes, there is no need to disassemble the entire device. First, use an Allen wrench to loosen the Allen bolt on the wedge 34 counterclockwise so that the bolt is disengaged from the threaded hole 25 of the base 20. Then, pull the wedge 34 out of the limiting hole 33 to release the fastening device 2 from the mounting base 30. Then, slide the base 20 with the old column 1 out along the slide groove 32 of the mounting base 30. If only the column 1 is damaged, remove the snap ring 24 with snap ring pliers, loosen the old column 1 so that it is disengaged from the threaded rod of the fixing seat 23. The fixing seat 23, base 20 and other undamaged parts do not need to be disassembled and can be reused. Finally, tighten the threaded hole 25 at the bottom of the new column 1 to the threaded rod of the fixing seat 23, and then reset the snap ring 24 to complete the replacement. The entire process does not require disassembling the connection structure between the mounting base 30 and the equipment.
