Description

Technical Field

[0001] The present invention relates to the field of transmission connection structures, and in particular to a moving part connection structure and method. Background Art

[0002] Commonly used two moving parts are connected to each other using special electromagnetic components or special hydraulic and pneumatic mechanisms; the special electromagnetic component is an independent control structure unit, which needs to be connected to an external power supply. Often this connection method requires a larger installation space. At the same time, in order to ensure the reliability and stability of the connection between the two mechanical moving parts, terminal detection must be added at the connection point of the moving parts. This method is usually used in open space locations. For the connection of some smaller two mechanical moving mechanisms, the space is very small, and it is difficult to have installation space for the connection using special electromagnetic components, which is basically impossible to achieve; similarly, when using a special hydraulic and pneumatic structure to connect two mechanical moving parts, it is necessary to add some external cylinders and oil cylinders, and supply air and oil externally through air pipes and oil pipes. The entire connection structure is also quite complicated, and it occupies a large volume. It is not suitable for the connection of two smaller mechanical moving parts, and the spatial position cannot meet the requirements of such a moving part connection. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a moving part connection structure and method. This structure only requires two mechanical moving parts to move to a certain position relative to each other, and then connect the two mechanical moving parts through a purely mechanical connection method. At the same time, the purely mechanical connection structure is not reversible and cannot be disengaged in the connected state. It has good reliability and stability. The whole process is simple in structure, stable and reliable, and the effect is obvious.

[0004] In order to achieve the above technical features, the purpose of the present invention is achieved as follows: a moving part connection structure includes an upper pull rod and a lower pull rod to be connected; an upper conical surface platform structure at the bottom end of the upper pull rod is clamped and matched with an upper conical hole of a spring collet, and an upper radial groove is processed at the end where the upper conical hole is located; The lower conical surface structure at the top end of the lower pull rod is tightly matched with the lower conical surface of the spring chuck, and a lower radial groove is processed at the end where the lower conical surface is located; The spring chuck is integrally sleeved inside the positioning sleeve; A stopper is positioned and installed on the lower pull rod through a pin shaft.

[0005] Preferably, the upper pull rod comprises an upper pull rod body, and the bottom end of the upper pull rod body is processed with an upper conical platform structure.

[0006] Preferably, the lower pull rod comprises a lower pull rod body, and the bottom end of the lower pull rod body is processed with a lower conical platform structure.

[0007] Preferably, a waist-shaped outer circle is processed in the middle of the outer circle of the spring chuck, the top end of the waist-shaped outer circle forms a top outer frustum, and the bottom end of the waist-shaped outer circle forms a bottom outer frustum; The center of the spring chuck is processed to have a center cavity, the inner top end of the center cavity is processed to form an upper conical surface, and the inner bottom end of the center cavity is processed to form a lower conical surface; The upper radial grooves are evenly arranged in a circumference and extend from the top outer cone to the starting position of the bottom outer cone; The lower radial grooves are evenly arranged in a circumference and extend from the bottom outer cone to the starting position of the top outer cone.

[0008] Preferably, the upper radial grooves and the lower radial grooves are evenly arranged in a staggered manner.

[0009] Preferably, there are at least two groups of upper radial grooves and lower radial grooves.

[0010] Preferably, there are three groups of upper radial grooves and three groups of lower radial grooves.

[0011] Preferably, the positioning sleeve comprises a positioning sleeve body, a positioning sleeve inner hole is processed at the center of the positioning sleeve body, the positioning sleeve inner hole cooperates with the spring chuck, and a mounting flange is processed on the outside of the positioning sleeve body.

[0012] Another aspect of the present invention provides a method for connecting a moving component connection structure, comprising the following steps: Step 1, installation of the stopper: Connect the stopper to the lower pull rod through a pin; Step 2, assembly of the lower pull rod and spring collet: Install the assembled lower tie rod into the spring collet. The lower conical surface structure of the lower tie rod expands the spring collet and enters the spring collet. At this time, the spring collet retracts to a free state. Step 3, assembly of spring collet and positioning sleeve: Install the spring chuck preliminarily assembled in step 2 into the inner hole of the positioning sleeve. There is a matching tolerance between the outer circle of the two ends of the spring chuck and the inner hole of the positioning sleeve. At this position, the spring chuck cannot expand radially. Step 4, ejection of the spring collet: The lower pull rod moves upward, and the stopper pushes the spring chuck upward. The outer cone of the top of the spring chuck matches the inner hole of the positioning sleeve and extends out of the inner hole of the positioning sleeve. At this time, the waist-shaped outer cone of the middle end of the spring chuck is in the inner hole of the positioning sleeve, and the outer cone of the top can expand radially. Step 5, assembly of the upper pull rod: The upper pull rod moves downward, and the upper conical platform structure on the upper pull rod enters the inner hole of the spring collet. When entering, the upper conical platform structure causes the top outer cone to expand radially. After entering, the spring collet elastically retracts to a free state; Step 6, locking the upper rod: The lower pull rod moves downward, and the conical surface of its lower conical platform structure fits with the lower conical hole on the spring chuck, pulling the spring chuck downward. The outer circle of the upper end of the spring chuck that fits with the inner hole of the positioning sleeve re-enters the inner hole of the positioning sleeve. The spring chuck is in a state where it cannot expand radially. The spring chuck continues to move downward until the upper conical hole of the spring chuck fits with the conical surface on the upper conical platform structure of the upper pull rod, and finally the upper pull rod is tightened, and the two moving parts are connected as one.

[0013] The present invention has the following beneficial effects: 1. The present invention utilizes a purely mechanical structure to realize the connection between two mechanical moving parts. The entire connection structure is compact and occupies a small space. The mechanical connection structure is not reversible and cannot be disengaged in the connected state. It has good reliability and stability. The entire connection structure has a small number of parts and is easy to assemble and debug.

[0014] 2. The present invention ensures that the top outer cone of the spring chuck can expand smoothly by adopting the above-mentioned upper radial groove, thereby realizing the insertion of the upper cone-shaped table structure, and can lock the upper cone-shaped table structure after insertion through the upper cone-shaped hole.

[0015] 3. The present invention ensures that the outer cone at the bottom of the spring chuck can expand smoothly by adopting the above-mentioned lower radial groove, thereby realizing the insertion of the lower cone-shaped table structure, and can lock the lower cone-shaped table structure after insertion through the lower cone-shaped hole.

[0016] 4. The present invention can reliably limit the two ends of the spring chuck to prevent it from expanding by adopting the above-mentioned positioning sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1: See also Figure 1-4 A moving part connection structure includes an upper rod 1 and a lower rod 4 to be connected; an upper conical platform structure 102 at the bottom end of the upper rod 1 is clamped and fitted with an upper conical hole 201 of a spring chuck 2, with an upper radial groove 205 machined at the end of the upper conical hole 201; a lower conical platform structure 402 at the top end of the lower rod 4 is clamped and fitted with a lower conical hole 203 of the spring chuck 2, with a lower radial groove 207 machined at the end of the lower conical hole 203; the spring chuck 2 is integrally mounted within a positioning sleeve 3; a stopper 5 is positioned and mounted on the lower rod 4 via a pin 6. The entire connection structure is compact, occupies a small space, and the mechanical connection structure is non-reversible, making it impossible to disengage in the connected state, thus providing excellent reliability and stability. The entire connection structure is composed of a small number of parts, and assembly and debugging are also convenient.

[0025] Furthermore, the upper rod 1 comprises an upper rod body 101, and the bottom end of the upper rod body 101 is processed with an upper conical platform structure 102. The upper rod 1 can be used to connect the upper moving parts.

[0026] Furthermore, the lower pull rod 4 includes a lower pull rod body 401, and the bottom end of the lower pull rod body 401 is processed with a lower conical platform structure 402. The lower pull rod 4 can be used to connect the lower moving parts.

[0027] Furthermore, the spring chuck 2 has a waist-shaped outer circle 204 machined into the middle of its outer circle. The top end of the waist-shaped outer circle 204 forms a top outer cone 206, and the bottom end of the waist-shaped outer circle 204 forms a bottom outer cone 208. A central cavity 202 is machined into the center of the spring chuck 2. The inner top of the central cavity 202 forms an upper conical hole 201, and the inner bottom of the central cavity 202 forms a lower conical hole 203. Upper radial grooves 205 are evenly arranged around the circumference and extend from the top outer cone 206 to the starting position of the bottom outer cone 208. Lower radial grooves 207 are evenly arranged around the circumference and extend from the bottom outer cone 208 to the starting position of the top outer cone 206. The spring chuck 2 described above can be used to lock and connect the upper and lower rods 1 and 4.

[0028] Furthermore, the upper radial grooves 205 and the lower radial grooves 207 are arranged in a staggered and uniform manner. By adopting the staggered and uniform arrangement, the spring chuck 2 is ensured to be subjected to uniform force.

[0029] Furthermore, there are at least two groups of the upper radial grooves 205 and the lower radial grooves 207. The above number ensures that the end of the spring clamp 2 can be expanded.

[0030] Furthermore, there are three groups of the upper radial grooves 205 and the lower radial grooves 207. The above number ensures that the end of the spring collet 2 can be expanded.

The lower conical platform structure 402 of the lower tie rod 4 expands the spring collet 2 and enters the spring collet 2. At this time, the spring collet 2 retracts to a free state. Step 3, assembly of spring collet 2 and positioning sleeve 3: Install the spring chuck 2 preliminarily assembled in step 2 into the inner hole of the positioning sleeve. There is a matching tolerance between the outer circle of the two ends of the spring chuck 2 and the inner hole of the positioning sleeve. At this position, the spring chuck 2 cannot expand radially. Step 4, ejection of spring collet 2: The lower pull rod 4 moves upward, and the stopper 5 pushes the spring chuck 2 to move upward. The outer cone 206 of the top of the spring chuck 2 matches the inner hole of the positioning sleeve and extends out of the inner hole of the positioning sleeve. At this time, the waist-shaped outer cone 204 at the middle end of the spring chuck 2 is in the inner hole of the positioning sleeve, and the outer cone 206 at the top can expand radially. Step 5, assembly of the upper pull rod 1: The upper rod 1 moves downward, and the upper conical platform structure 102 on the upper rod 1 enters the inner hole of the spring collet 2. When entering, the upper conical platform structure 102 causes the top outer cone 206 to expand radially. After entering, the spring collet elastically retracts to a free state; Step 6, locking the upper pull rod 1: The lower pull rod 4 moves downward, and the conical surface of its lower conical platform structure 402 fits with the lower conical hole 203 on the spring chuck 2, pulling the spring chuck 2 downward. The outer circle of the upper end of the spring chuck 2 that fits with the inner hole of the positioning sleeve re-enters the inner hole of the positioning sleeve, and the spring chuck 2 is in a state where it cannot expand radially. The spring chuck continues to move downward until the upper conical hole 201 of the spring chuck fits with the conical surface on the upper conical platform structure 102 of the upper pull rod 1, and finally the upper pull rod 1 is tightened, and the two moving parts are connected as one.
