Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary devices for block forming machines, specifically to a guide column locking mechanism. Background Technology
[0002] The existing block molding machine typically uses clamping or expansion sleeve to lock the guide column and the lower slide plate. This process is prone to loosening due to long-term vibration during equipment operation, which can cause the lower slide plate and guide column to become out of sync, resulting in jamming or obstructed lifting. It can also cause quality problems in the product when the mold is demolded. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a guide post locking mechanism to solve the technical problems mentioned in the background.
[0004] To achieve the above objectives, this utility model provides a guide post locking mechanism, including a locking block and steel balls. The locking block includes a locking sleeve and a locking spring clip. The locking sleeve is sleeved on the outside of the locking spring clip, and the locking spring clip is elastic. The locking sleeve is fixed to the guide post by pressing the locking spring clip. The inner wall of the locking block is provided with a first steel ball groove, and the side wall of the guide post is provided with a second steel ball groove at a corresponding position. There are two locking blocks, which are arranged opposite to each other and connected to each other. The first steel ball groove and the second steel ball groove of the two locking blocks form a spherical groove. The steel ball is placed in the spherical groove and abuts against the inner wall of the spherical groove.
[0005] The locking sleeve includes a sleeve portion and a fixing portion. The lower end of the sleeve portion is connected to the fixing portion. The sleeve portion is sleeved on the outside of the locking spring clip. Each of the four corners of the fixing portion is provided with a fixing hole, and the axial direction of the fixing hole is the same as the axial direction of the sleeve portion. A bolt passes through the fixing hole to connect two locking blocks arranged opposite each other.
[0006] The locking spring clip is a conical thin-walled sleeve with multiple evenly distributed elastic grooves on its outer circumference. Two adjacent elastic grooves are connected to the two ends of the locking spring clip, respectively. The length direction of the elastic groove is the same as the axial direction of the locking spring clip. The locking spring clip contracts or expands circumferentially through the deformation of the elastic groove.
[0007] The sleeve is a tapered sleeve. The inner diameter of the sleeve gradually decreases at the end away from the fixed part. The minimum inner diameter of the sleeve is smaller than the minimum outer diameter of the locking spring collet when it is not under force, and the maximum inner diameter of the sleeve is larger than the maximum outer diameter of the locking spring collet when it is not under force.
[0008] The first steel ball groove is located on the inner wall of the connection between the two locking spring clips. The first steel ball groove is a groove in the shape of a quarter steel ball, and the first steel ball grooves of the two locking spring clips surround each other to form a hemispherical groove.
[0009] The second steel ball groove is located at the position where the guide post is connected to the locking sleeve, and the second steel ball groove is a groove shaped like half a steel ball.
[0010] The beneficial effects of the guide post locking mechanism obtained through the above technical solution are:
[0011] By placing steel balls between the locking block and the guide post, the steel balls are firmly locked in the circular groove between the guide post and the locking block, making the fixation between the locking block and the guide post more secure and preventing them from shifting in the vertical direction.
[0012] It enhances axial stability and prevents damage to the locking mechanism caused by minute axial displacement due to vibration. Attached Figure Description

Detailed Implementation
[0019] Further embodiments of the present invention will be described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0020] like Figure 1-5As shown, a guide post locking mechanism includes a locking block 1 and a steel ball 2. The locking block 1 includes a locking sleeve 11 and a locking spring clip 12. The locking sleeve 11 is sleeved on the outside of the locking spring clip 12. The locking spring clip 12 is elastic. The locking sleeve 11 is fixed to the guide post 3 by pressing the locking spring clip 12. The inner wall of the locking block 1 is provided with a first steel ball groove 1a, and the side wall of the guide post 3 is provided with a second steel ball groove 3a at a corresponding position. There are two locking blocks 1. The two locking blocks 1 are arranged opposite each other and connected to each other. The first steel ball groove 1a and the second steel ball groove 3a of the two locking blocks 1 form a spherical groove. The steel ball 2 is placed in the spherical groove and abuts against the inner wall of the spherical groove. Because the steel ball 2 is stuck in the spherical groove formed by the guide post 3 and the locking block 1, the steel ball 2 needs to overcome the resistance of both the first steel ball groove 1a and the second steel ball groove 3a simultaneously to roll or slide out. Therefore, the steel ball 2 is firmly stuck in the spherical groove, and the steel ball 2 acts as a "stop pin" or "positioning key," eliminating the possibility of vertical movement and circumferential rotation. The volume of the spherical groove should match the volume of the steel ball 2 to ensure that the steel ball 2 is accurately positioned within the spherical groove and provides sufficient contact area.
[0021] The locking sleeve 11 includes a sleeve portion 111 and a fixing portion 112. The lower end of the sleeve portion 111 is connected to the fixing portion 112. The sleeve portion 111 is sleeved on the outside of the locking spring clip 12. The fixing portion 112 is provided with fixing holes 112a at each of its four corners. The axial direction of the fixing holes 112a is the same as the axial direction of the sleeve portion 111. The bolt 4 passes through the fixing holes 112a and connects two locking blocks 1 arranged opposite each other.
[0022] The locking spring clip 12 is a conical thin-walled sleeve with multiple evenly distributed elastic grooves 12a on its outer circumference. Two adjacent elastic grooves 12a are connected to the two ends of the locking spring clip respectively. The length direction of the elastic grooves 12a is the same as the axial direction of the locking spring clip 12. The locking spring clip 12 contracts or expands circumferentially through the deformation of the elastic grooves 12a. When the outer circumference of the locking spring clip 12 is squeezed, the spring grooves 12a are squeezed and narrowed, causing the outer circumference of the locking spring clip 12 to contract and tighten inward.
[0023] The sleeve portion 111 is a conical sleeve. The inner diameter of the sleeve portion 111 gradually decreases at the end away from the fixed portion 112. The minimum inner diameter of the sleeve portion 111 is smaller than the minimum outer diameter of the locking spring collet 12 when it is not under force, and the maximum inner diameter of the sleeve portion 111 is larger than the maximum outer diameter of the locking spring collet 12 when it is not under force. Since the minimum inner diameter of the sleeve portion 111 is smaller than the minimum outer diameter of the locking spring collet 12 when it is not under force, by tightening the locking spring collet 12 inside the locking sleeve 11, the locking spring collet 12 is circumferentially compressed, forcing the locking spring collet 12 to undergo elastic deformation (contraction), thereby radially gripping the guide post 3.
[0024] The first steel ball groove 1a is provided on the inner wall of the connection between the two locking spring clips 12. The first steel ball groove 1a is a groove in the shape of a quarter steel ball, and the first steel ball grooves 1a of the two locking spring clips 12 surround each other to form a hemispherical groove.
[0025] The second steel ball groove 3a is located at the position where the guide post 3 is connected to the locking sleeve 11, and the second steel ball groove 3a is a groove in the shape of half a steel ball.
[0026] In use, insert the locking spring clip 12 into the locking sleeve 11, then put the two locking blocks 1 on the outside of the guide post 3 respectively, align the first ball groove 1a of the lower locking block 1 with the second ball groove 3a of the guide post 3, put in the ball 2, and then align the upper locking block 1 with the lower locking block 1. At this time, the ball 2 is fixed in the spherical groove surrounded by the two locking blocks 1 and the guide post 3. Then, mill the corresponding through holes in the lower guide plate 5 at the positions of the sleeve part 111 and the fixing hole 112a, so that it fits the fixing part 112. The bolt passes through the fixing holes 11a of the two locking sleeves 11 and the through holes at the positions of the fixing holes 112a of the lower guide plate in sequence, and is fixed by nuts.
