A skeleton shell shaping mechanism

Abstract

This utility model relates to the field of skeleton assembly, and more particularly to a skeleton shell shaping mechanism. The clamping mechanism includes multiple shaping blocks that converge toward the center point. These shaping blocks, through convergence, form a shaping platform that applies uniform pressure to the outside of the positioning teeth. The inner top mechanism includes an inner top block and a lower pressure plate surrounding the inner top block. The inner top block passes through the shell on the lower pressure plate and compresses the positioning teeth that intersect with the movement path of the inner top block. It also forms a positioning mechanism that fixes the shell during shaping by constraining the positioning teeth with the shaping platform. First, the positioning teeth of the annular structure of the shell are shaped internally and externally. Through the cooperation of the clamping mechanism and the inner top mechanism, a structural repair effect is achieved. Second, since the positioning teeth have sharp points, the clamping mechanism is chosen to avoid contact with the sharp points and apply pressure from the side of the sharp points, thus avoiding the problem of secondary bending of the sharp points.

Description

Technical Field

[0001] This utility model relates to the field of skeleton assembly, and more particularly to a skeleton shell shaping mechanism. Background Technology

[0002] like Figure 11 As shown, it includes a shell 3 and a frame 6. The shell 3 is fitted onto the frame 6 and is used to wrap the frame 6 with the coil wound on it.

[0003] like Figure 12 As shown, Figure 2 A perspective view of this housing 3 is shown. Multiple positioning teeth 31 are provided on the inner annular surface of the housing 3. These positioning teeth 31 penetrate into the inner annular surface of the skeleton 6, providing a positioning effect for the skeleton 6.

[0004] Since the outer shell 3 is formed by one-piece stamping, the supplier's stamping process has a problem with low precision, which causes the positioning teeth 31 to tilt inward or outward. The positioning teeth 31 are made of metal material. When they tilt inward, it will affect the stability of the skeleton 6 inside the outer shell 3. The entire skeleton 6 is loose inside the outer shell 3. When it tilts outward, it will abut against the inner wall of the skeleton 6, and even the most basic assembly will be a problem.

[0005] The use of this housing 3 is a new requirement of the customer. The traditional frame 6 does not need to be assembled with the housing 3. For this new application of the coil, at present, there is no corresponding solution to solve the problem of the tilt of the positioning teeth 31. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a skeleton shell shaping mechanism for correcting the tilting of the positioning teeth.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a skeleton shell shaping mechanism, characterized in that it includes a clamping mechanism and an inner top mechanism that are opposite to each other. The clamping mechanism includes a plurality of shaping blocks that converge toward the center point. The shaping blocks converge to form a shaping platform that applies uniform pressure to the outside of the positioning teeth. The inner top mechanism includes an inner top block and a lower pressure plate surrounding the inner top block. The inner top block passes through the shell on the lower pressure plate and squeezes the positioning teeth that intersect with the movement path of the inner top block. It forms a positioning mechanism that fixes the shell during shaping in the form of a constraint on the positioning teeth with the shaping platform.

[0008] The beneficial effects of this utility model are:

[0009] 1. First, the inner and outer shapes of the positioning teeth of the ring structure of the outer shell were shaped. Through the cooperation of the clamping mechanism and the inner top mechanism, a structural repair effect was achieved. Second, since the positioning teeth have sharp points, the clamping mechanism was selected to avoid contact with the sharp points and apply pressure from the side of the sharp points, which can avoid the problem of secondary bending of the sharp points.

[0010] 2. In addition, without exception, the outward-curving positioning teeth are all arc-shaped when viewed from the side. For structural repair, the multiple shaping blocks that make up the shaping table constrain each other to converge their compression process. The purpose of this mutual constraint is to provide the maximum shaping pressure for normal use, to prevent excessive pressure from damaging the inner top block, and to avoid excessive shaping pressure from causing the positioning teeth to flatten.

[0011] The aforementioned clamping mechanism includes multiple clamping arms. In this embodiment, the structure needs to provide a very large clamping force to achieve the structural repair effect. Specifically, this clamping is achieved by raising and lowering the clamping arms to pull the shaping blocks together. The outer surface of the shaping blocks is provided with inclined grooves, and the inner surface of the clamping arms is embedded in the inclined grooves and is slidably connected to the inclined grooves. Viewed from bottom to top, the inclined grooves are inclined from the outside to the inside. Therefore, when the clamping arms are raised, the shaping blocks move towards their center point under the action of the inclined grooves. Similarly, when the clamping arms are lowered, the shaping blocks move outward under the action of the inclined grooves.

[0012] The inner surface of the clamping arm is designed as a slider structure, which forms a sliding connection with the slide rail in the inclined groove.

[0013] The clamping mechanism includes a clamping cylinder and a sliding module. The clamping arm is located on the movable end of the sliding module, and the piston rod of the clamping cylinder is connected to the movable end. Specifically, this movable module provides a vertical lifting effect.

[0014] The top edge of the inner top block is curved, which reduces friction and damage to the positioning teeth when they come into contact with them.

[0015] The lower pressure plate has an opening, which is divided into multiple areas. The surface of the inner top block is composed of multiple inner tops that fit the aforementioned areas. Specifically, the inner tops are formed by setting cross grooves on the inner top block. Since the inner top block has a certain height, it is inevitable that it will tilt to some extent due to the reaction force provided by the positioning teeth during the repair process. With multiple openings and the design of dividing the inner top block into multiple inner tops, the control of a single inner top is smaller than the control of the entire inner top block by only one opening, thus improving the shaping effect.

[0016] The inner jacking mechanism includes an inner jacking cylinder, and the inner jacking block is directly mounted on the piston rod of the inner jacking cylinder.

[0017] The inner top mechanism also includes a pressure fixing plate, an elastic component, and a first guide rod. The pressure fixing plate is directly fitted onto the circumference of the inner top block and moves up and down with the inner top block. The first guide rod and the elastic component are located between the pressure fixing plate and the pressure plate. The pressure plate abuts against the bottom surface of the outer shell. In the early stage of repair, it not only provides a basic placement effect, but also plays a preliminary positioning role.

[0018] The working principle of this utility model:

[0019] S1, first place the outer shell on the lower pressure plate and put it on the part of the inner top block that passes through the lower pressure plate;

[0020] S2, the inner top cylinder pushes the inner fixed block to lift the outer shell to the clamping mechanism above it;

[0021] S3, the piston rod in the clamping cylinder is in a retracted state, and the main drive module drives the clamping mechanism to move towards the inner push mechanism. At this time, the multiple shaping blocks separated from the shaping table are distributed outside the positioning teeth.

[0022] S4, the clamping cylinder pushes the movable end on the sliding module to move through its piston rod, causing the clamping arm to move into the outer shell. At the same time, under the action of the inclined groove, the shaping blocks move closer to each other, finally forming a shaping table for shaping and repair. Attached Figure Description

[0035] like Figure 1-12 As shown, a skeleton shell shaping mechanism is characterized by comprising a clamping mechanism 1 and an inner top mechanism 2 that are opposite to each other. The clamping mechanism 1 includes a plurality of shaping blocks 100 that converge toward a central point. The shaping blocks 100 converge to form a shaping platform 101 that applies uniform pressure to the outside of the positioning teeth 31. The inner top mechanism 2 includes an inner top block 21 and a lower pressure plate 22 surrounding the inner top block 21. The inner top block 21 passes through the shell 3 on the lower pressure plate 22 and compresses the positioning teeth 31 that intersect with the movement path of the inner top block 21. It forms a positioning mechanism for fixing the shell 3 during shaping by constraining the positioning teeth 31 with the shaping platform 101.

[0036] The beneficial effects of this utility model are:

[0037] 1. First, the positioning teeth 31 of the ring structure of the outer shell 3 were shaped inside and out. Through the cooperation of the clamping mechanism 1 and the inner top mechanism 2, a structural repair effect was achieved. Second, since the positioning teeth 31 have sharp points, the clamping mechanism 1 was selected so as not to contact the sharp points, but to apply pressure from the side of the sharp points, which can avoid the problem of secondary bending of the sharp points.

[0038] 2. In addition, without exception, the outward-curving positioning teeth 31 are all arc-shaped when viewed from the side. For structural repair, the multiple shaping blocks 100 that make up the shaping table 101 constrain each other to converge during the shrinkage process. The purpose of this mutual constraint is to provide the maximum shaping pressure for normal use, to prevent excessive pressure from damaging the inner top block 21, and to avoid excessive shaping pressure from causing the positioning teeth 31 to flatten.

[0039] The aforementioned clamping mechanism 1 includes multiple clamping arms 102. In this embodiment, the structure needs to provide a very large clamping force to achieve the structural repair effect. Specifically, this clamping is achieved by raising and lowering the clamping arms 102 to pull the shaping blocks 100 together. The outer surface of the shaping block 100 is provided with a groove 100-a, and the inner surface of the clamping arm 102 is embedded in the groove 100-a and is slidably connected to the groove 100-a. From bottom to top, the groove 100-a is inclined from the outside to the inside. Therefore, when the clamping arm 102 is raised, the shaping blocks 100 move towards their center point under the action of the groove 100-a. Similarly, when the clamping arm 102 is lowered, the shaping blocks 100 move outward under the action of the groove 100-a.

[0040] The inner surface of the clamping arm 102 is designed as a slider structure, which forms a sliding connection with the slide rail in the inclined groove 100-a.

[0041] The clamping mechanism 1 includes a clamping cylinder 103 and a sliding module 104. The clamping arm 102 is disposed on the movable end of the sliding module 104, and the piston rod of the clamping cylinder 103 is connected to the movable end. Specifically, this movable module provides a vertical lifting effect.

[0042] The top edge of the inner top block 21 is an arc surface, which can reduce friction on the positioning teeth 31 and reduce damage to the positioning teeth 31 when it comes into contact with them.

[0043] The lower pressure plate 22 has an opening, which is divided into multiple areas 22a. The surface of the inner top block 21 is divided into multiple inner tops 21a that are adapted to the areas 22a. Specifically, the inner tops 21a are formed by setting cross grooves on the inner top block 21. Since the inner top block 21 has a certain height, it will inevitably tilt to some extent due to the reaction force provided by the positioning teeth 31 during the repair process. With multiple openings and the design of dividing the inner top block 21 into multiple inner tops 21a, the control of a single inner top 21a is smaller than the control of the entire inner top block 21 by only one opening, thus improving the shaping effect.

[0044] The inner jacking mechanism 2 includes an inner jacking cylinder 23, and the inner jacking block 21 is directly mounted on the piston rod of the inner jacking cylinder 23.

[0045] The inner top mechanism 2 also includes a pressing and fixing plate 24, an elastic component 25, and a first guide rod 26. The pressing and fixing plate 24 is directly fitted onto the circumferential surface of the inner top block 21 and moves up and down with the inner top block 21. The first guide rod 26 and the elastic component 25 are located between the pressing and fixing plate 24 and the pressing plate 22. The pressing plate 22 abuts against the bottom surface of the outer shell 3. In the early stage of repair, it not only provides a basic placement effect, but also plays a preliminary positioning role.

[0046] The aforementioned elastic component 25 is a spring.

[0047] The working principle of this utility model:

[0048] S1, first place the outer shell 3 on the lower pressure plate 22 and fit it onto the inner top block 21 that passes through the lower pressure plate 22;

[0049] S2, the inner top cylinder 23 pushes the inner top block 21 to lift the outer shell 3 towards the clamping mechanism 1 above it;

[0050] S3, the piston rod in the clamping cylinder 103 is in a retracted state, and the main drive module 5 drives the clamping mechanism 1 to move towards the inner push mechanism 2. At this time, the multiple shaping blocks 100 separated from the shaping table 101 are distributed outside the positioning teeth 31.

[0051] S4, the clamping cylinder 103 pushes the movable end on the sliding module 104 to move through its piston rod, causing the clamping arm 102 to rise. At the same time, under the action of the inclined groove 100-a, the shaping blocks 100 move closer to each other, finally forming the shaping table 101 for shaping and repair.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
