Description

Technical Field

[0001] This utility model relates to the field of stamping die manufacturing technology, specifically to an independent guide post assembly for preventing loosening. Background Technology

[0002] Stamping is a commonly used metal processing method, and it is a processing method with high production efficiency and low material consumption. In the process, pressure is applied to the sheet metal using dies and stamping equipment to cause plastic deformation or separation of the sheet metal. Among them, the die is an important structural component, while independent guide pillars can play a protective and guiding role in stamping production.

[0003] According to a search, Chinese patent document, publication number CN207756741U, discloses an independent guide post assembly with anti-loosening gaskets, including a base, guide post, upper guide sleeve, locking pin, and anti-loosening gaskets. The lower end of the guide post is fixed to the base, and the upper guide sleeve is slidably fitted to the upper part of the guide post. The upper guide sleeve has pin holes at its four corners, in which locking pins are installed. Each locking pin includes a pin shaft and a cylindrical flange at one end of the pin shaft, with the pin shaft passing through the pin hole from bottom to top. An anti-loosening gasket is provided between the two opposite pin holes of the upper guide sleeve and the corresponding locking pin flange in the width direction. This invention can effectively prevent locking pin loosening and damage to the mold. However, the overall structure, while increasing connection stability through anti-loosening gaskets, is relatively simple, lacks a limiting and fixing structure for the locking pin, resulting in poor anti-loosening effect and low practicality.

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an independent guide post assembly for preventing loosening. By using a limiting plate to limit and fix the connecting pin, the anti-loosening effect is increased, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an independent guide post assembly for preventing loosening, comprising a base, a guide post rod fixedly connected to the upper end of the base, an upper guide sleeve sleeved on the upper end of the guide post rod, an upper top seat fixedly connected to the upper end of the upper guide sleeve, a ball bearing assembly provided between the upper guide sleeve and the guide post rod, fixing pins provided on the sides of the surfaces of the base and the upper top seat, a limit plate provided on the outer side of the fixing pins, and engaging assemblies provided on the surfaces of the base and the upper top seat;

[0008] The ball assembly includes a ball sleeve and steel balls. A ball sleeve is provided between the guide rod and the upper guide sleeve. Steel balls are rotatably connected to the surface of the ball sleeve. The steel balls are distributed in a circular array around the center of the ball sleeve. The upper guide sleeve and the guide rod are slidably connected by the steel balls.

[0009] Preferably, the upper top seat and the guide rod are sleeved together, and the upper top seat and the base have the same length and width.

[0010] The above technical solution facilitates the lifting and sliding of the upper guide sleeve. By using steel balls to contact the guide rod and the upper guide sleeve respectively, the friction force during the sliding of the upper guide sleeve is reduced, the wear on the guide rod is reduced, and the practicality is improved.

[0011] Preferably, the fixing pins are arranged symmetrically in two sets about the vertical center lines of the base and the top seat, and each set has two fixing pins.

[0012] The above technical solution facilitates the installation and fixation of the base and the top seat with multiple fixing pins, increasing the stability of the fixation.

[0013] Preferably, the limiting plate has a U-shaped structure design, and a positioning block is fixedly connected to the inner side of the limiting plate. The positioning block and the fixing pin are mutually compatible.

[0014] By using the above technical solution, the limiting plate is engaged with the outer side of the base and the top seat, so that the positioning block enters the end face groove of the fixing pin and engages, thereby limiting the fixing pin and preventing it from loosening, thus improving the anti-loosening effect.

[0015] Preferably, the engaging assembly includes an mounting groove, an engaging block, a connecting spring, and an engaging slot. The surfaces of the base and the top seat are provided with mounting grooves. An engaging block is slidably connected in the mounting groove. A connecting spring is fixedly connected to the rear end of the engaging block. Engaging slots are provided on both the front and rear sides of the lower end of the limiting plate.

[0016] The above technical solution uses the engagement of the locking block and the locking groove to fix the limiting plate, so that the limiting plate covers the outside of the fixing pin, preventing the fixing pin from loosening and achieving anti-loosening protection.

[0017] Preferably, the mounting grooves are symmetrically arranged in two sets about the vertical center lines of the base and the top seat. Each set of mounting grooves has two grooves located on the front and rear sides of the base and the top seat. The end of the connecting spring away from the locking block is fixedly connected to the base and the top seat, and the locking block and the locking groove are engaged.

[0018] The above technical solution utilizes the elasticity of the connecting spring to cause the locking block to protrude outward from the mounting groove, thereby engaging with the locking groove to fix the limiting plate. During disassembly, the locking block is squeezed to enter the mounting groove, and the limiting plate can be removed to disassemble the fixing pin.

[0019] Compared with the prior art, this utility model provides an independent guide post assembly that prevents loosening, which has the following beneficial effects:

[0020] 1. This utility model uses steel balls to contact the guide rod and the upper guide sleeve respectively, which reduces friction on the guide rod when the upper guide sleeve slides, thus improving its practicality.

[0021] 2. This utility model uses a limiting plate to cover the outside of the fixing pin to prevent the fixing pin from loosening and achieve anti-loosening protection. It also uses the elasticity of the connecting spring to make the locking block protrude outward of the mounting groove, thereby locking with the locking groove to fix the limiting plate. When disassembling, the locking block is squeezed to make it enter the mounting groove, and the fixing pin can be disassembled by removing the limiting plate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figure 1-3 As shown, the present invention provides an anti-loosening independent guide post assembly, including a base 1, a guide post rod 2 fixedly connected to the upper end of the base 1, an upper guide sleeve 3 sleeved on the upper end of the surface of the guide post rod 2, an upper top seat 4 fixedly connected to the upper end of the upper guide sleeve 3, a ball bearing assembly 5 provided between the upper guide sleeve 3 and the guide post rod 2, fixing pins 6 provided on the sides of the surfaces of the base 1 and the upper top seat 4, a limit plate 7 provided on the outer side of the fixing pins 6, and a locking assembly 8 provided on the surfaces of the base 1 and the upper top seat 4.

[0030] The ball assembly 5 includes a ball sleeve 51 and steel balls 52. The ball sleeve 51 is disposed between the guide rod 2 and the upper guide sleeve 3. The surface of the ball sleeve 51 is rotatably connected to the steel balls 52. The steel balls 52 are distributed in a circular array around the center of the ball sleeve 51. The upper guide sleeve 3 and the guide rod 2 are slidably connected through the steel balls 52.

[0031] Specifically, the upper top seat 4 and the guide rod 2 are sleeved together, and the upper top seat 4 and the base 1 have the same length and width. The advantage is that it facilitates the lifting and sliding of the upper guide sleeve 3, and the steel balls 52 contact the guide rod 2 and the upper guide sleeve 3 respectively, reducing the friction when the upper guide sleeve 3 slides, reducing the wear on the guide rod 2, and improving practicality.

[0032] Specifically, two sets of fixing pins 6 are symmetrically arranged about the vertical center lines of the base 1 and the upper top seat 4, with two fixing pins 6 in each set. The advantage is that multiple fixing pins 6 facilitate the installation and fixation of the base 1 and the upper top seat 4, increasing the stability of the fixation.

[0033] Specifically, the limiting plate 7 has a U-shaped structure design, and a positioning block 71 is fixedly connected to the inner side of the limiting plate 7. The positioning block 71 and the fixing pin 6 are mutually compatible. The advantage is that by using the limiting plate 7 to engage with the outer sides of the base 1 and the upper top seat 4, the positioning block 71 enters the end face groove of the fixing pin 6 for engagement, thereby limiting the fixing pin 6 and preventing it from loosening, thus improving the anti-loosening effect.

[0034] Example 2:

[0035] like Figure 3-4 As shown, this is an improvement on the previous embodiment. Specifically, the engaging assembly 8 includes a mounting groove 81, an engaging block 82, a connecting spring 83, and an engaging slot 84. The mounting groove 81 is formed on the surfaces of the base 1 and the upper top seat 4. The engaging block 82 is slidably connected in the mounting groove 81. The connecting spring 83 is fixedly connected to the rear end of the engaging block 82. Engaging slots 84 are formed on both the front and rear sides of the lower end of the limiting plate 7. The advantage is that the engaging of the engaging block 82 and the engaging slot 84 achieves the fixation of the limiting plate 7, so that the limiting plate 7 covers the outside of the fixing pin 6, preventing the fixing pin 6 from loosening and achieving anti-loosening protection.

[0036] Specifically, two sets of mounting slots 81 are symmetrically arranged about the vertical center lines of the base 1 and the upper top seat 4. Each set of mounting slots 81 has two slots located on the front and rear sides of the base 1 and the upper top seat 4. The end of the connecting spring 83 away from the locking block 82 is fixedly connected to the base 1 and the upper top seat 4. The locking block 82 is engaged with the locking slot 84. The advantage is that the elasticity of the connecting spring 83 causes the locking block 82 to protrude outward from the mounting slot 81, thereby engaging with the locking slot 84 to fix the limiting plate 7. During disassembly, the locking block 82 is squeezed into the mounting slot 81, and the limiting plate 7 can be removed to disassemble the fixing pin 6.

[0037] In use, the base 1 and the upper top seat 4 are connected by a mating interface, and the independent guide column assembly is fixedly connected by a fixing pin 6. During sliding, the upper guide sleeve 3 slides up and down on the guide column rod 2, and the steel balls 52 contact the guide column rod 2 and the upper guide sleeve 3 respectively, reducing the friction of the upper guide sleeve 3 during sliding, reducing the wear on the guide column rod 2, and improving practicality. At the same time, the limiting plate 7 covers the outside of the fixing pin 6 to prevent the fixing pin 6 from loosening, achieving anti-loosening protection. The elasticity of the connecting spring 83 causes the locking block 82 to protrude outward from the mounting groove 81, thereby engaging with the locking groove 84 to fix the limiting plate 7. During disassembly, the locking block 82 is squeezed to enter the mounting groove 81, and the fixing pin 6 can be disassembled by removing the limiting plate 7.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
