Description

Technical Field

[0001] The utility model relates to the technical field of compression spring tooling, in particular to a compression spring locking component. Background Art

[0002] Spring hot pressing technology is a method to improve the performance of springs. It mainly changes the properties and structure of its materials by heating and pressure treating the springs. This technology can improve the strength, toughness, wear resistance and fatigue life of the springs. Considering the cost and process, it is the best production process for storing elastic stress. It is to compress the wound spring to a specified height, and at the same time constrain the inner diameter or outer diameter of the spring to keep the spring straight and in a fixed compressed state. It enters the heat treatment furnace, is heated to a specified temperature and maintained for a certain period of time, and then the air is cooled to room temperature after it is taken out of the furnace. Finally, the spring is released to a free state. The above is the most advanced process for storing elastic stress in springs. However, the tooling for compressing springs usually uses thread locking, which is cumbersome and slow to disassemble, or requires complex tooling equipment to achieve spring compression. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a compression spring locking component, through which the spring can be compressed on the core rod to form a self-locking structure, which is convenient for completing the compression tooling of the spring by hot strong pressing, and after the spring is cooled after the heat treatment, the spring can also be disassembled and assembled conveniently and quickly, thereby improving the disassembly speed of the spring from the core rod.

[0004] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0005] A compression spring locking component comprises: a spring, a core rod sleeved inside the spring, a disc installed at the bottom of the core rod, an elastic clamp arranged at the top of the core rod, and a locking component arranged between the core rod and the elastic clamp, wherein the locking component comprises: an elastic clamping claw, a collar and a groove, and is used to limit and lock the spring.

[0006] Preferably, a plurality of elastic claws are provided at the bottom of the elastic chuck, and rings are provided on the outside of the plurality of elastic claws. Grooves are respectively provided on both sides of the top of the core rod. The spring can be pressed onto the core rod through the elastic claws, the rings and the grooves to form a self-locking structure, which is convenient for completing the compression tooling of the spring by hot pressing. After the spring is cooled after the heat treatment, the spring can be disassembled and assembled conveniently and quickly, thereby improving the disassembly speed of the spring.

[0007] Preferably, the inner sides of the bottom ends of the plurality of elastic clamps are all hook-shaped structures, and the inner sides of the bottom ends of the elastic clamps are clamped and fixed with the groove. Since the inner sides of the bottom ends of the plurality of elastic clamps are all hook-shaped structures, they fit perfectly with the groove, making it easy to hook the elastic clamps inside the groove.

[0008] Preferably, the multiple elastic jaws and the elastic chuck form an annular limiting cavity, and the width of the annular limiting cavity is larger than the core rod. Since the multiple elastic jaws and the elastic chuck form the annular limiting cavity, the core rod can be wrapped by the annular limiting cavity, thereby facilitating the compression and limiting of the spring on the core rod.

[0009] Preferably, the diameter of the core rod is consistent with the inner diameter of the spring, and the core rod and the disc are in a "T" shape. The core rod and the disc are arranged in a "T" shape, and the disc just supports the bottom end of the spring. The diameter of the core rod is consistent with the inner diameter of the spring. The inside of the spring is tightly attached to the core rod, which plays a role in constraining the inner diameter of the spring, so that the straightness of the spring can be maintained when the spring is compressed.

[0010] Preferably, a sleeve hole is provided inside the ring, and the connection between the multiple elastic claws and the elastic clamp is an arc-shaped structure, and the sleeve hole is tightly fitted with the connection between the elastic claws and the elastic clamp. Since the connection between the multiple elastic claws and the elastic clamp is an arc-shaped structure, when the ring slides upward, it just limits the ring to prevent the ring from moving out from the top of the elastic clamp, and the bottom parts of the multiple elastic claws are in an open state, which can also limit the ring to prevent the ring from falling off the elastic claws.

[0011] Preferably, a threaded head is installed in the middle of the bottom end of the core rod, and a fixing screw hole threadedly connected to the threaded head is opened in the middle of the disk. The core rod is installed in the fixing screw hole in the middle of the disk through the threaded head. The core rod is easy to remove from the disk, and core rods of different lengths can be replaced, thereby compressing springs of different lengths.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0023] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1

[0025] like Figure 1-Figure 7 As shown, a compression spring locking component includes: a spring 1, a core rod 2 sleeved inside the spring 1, a disk 3 installed at the bottom of the core rod 2, an elastic clamp 4 arranged on the top of the core rod 2, and a locking component arranged between the core rod 2 and the elastic clamp 4, the locking component including: an elastic clamping claw 401, a ring 402 and a groove 5, which are used to limit and lock the spring 1.

[0026] Among them, reference Figure 1-Figure 7 As shown, a plurality of elastic clamping claws 401 are provided at the bottom of the elastic clamping head 4, a sleeve ring 402 is provided outside the plurality of elastic clamping claws 401, and grooves 5 are respectively provided on both sides of the top of the core rod 2.

[0027] When the spring 1 is compressed, the spring 1 is first put on the core rod 2, and the elastic clamp 4 and the elastic clamping claw 401 are pressed down from the upper end of the core rod 2. The pressure acts directly on the ring 402. During the downward pressing process of the elastic clamp 4, the elastic clamping claw 401 structure of the elastic clamp 4 moves downward along the core rod 2 and contacts with the top of the spring 1. At this time, the spring 1 begins to be compressed until the elastic clamping claw 401 structure of the spring clamp 1 descends to the groove 5 outside the core rod 2. Since the ring 402 is always subjected to the tightening force of the ring 402 when moving downward at the elastic clamping claw 401, multiple elastic clamping claws 401 gather towards the middle, and then the elastic clamping claws 401 are stuck in the groove 5 outside the core rod 2. At the same time, the ring 402 continues to descend and is tightly mounted on the outer walls of multiple elastic clamping claws 401, so that the spring 1 is pressed on the core rod 2 to form a self-locking structure, which is convenient for completing the compression tooling of the spring 1 by hot pressing.

[0028] After the spring 1 is heat treated and cooled, it is necessary to loosen and remove the spring 1 from the core rod 2. Since the ring 402 tightens and covers the multiple elastic claws 401 and is tightly wrapped around the outer walls of the multiple elastic claws 401, to relax the multiple elastic claws 401, it is only necessary to pull the ring 402 upwards. As the ring 402 slides upward to the top of the multiple elastic claws 401, the tightening force on the multiple elastic claws 401 is released, so that the multiple elastic claws 401 are completely released, and the elastic claws 401 are opened and disengaged from the inside of the groove 5, that is, the elastic clamp 4 is separated from the core rod 2, allowing the spring 1 to be released to a free state on the core rod 2. After the spring 1 completes the heat and pressure treatment, the spring 1 can be disassembled and assembled conveniently and quickly, thereby improving the disassembly speed of the spring 1.

[0029] Among them, reference Figure 1-Figure 5 As shown, the inner sides of the bottom ends of the multiple elastic clamps 401 are all hook-shaped structures, and the inner sides of the bottom ends of the elastic clamps 401 are clamped and fixed with the groove 5. When the elastic clamp 4 drives the multiple elastic clamps 401 to move down to the groove 5 outside the core rod 2, since the inner sides of the bottom ends of the multiple elastic clamps 401 are all hook-shaped structures, they just fit together with the groove 5, making it easy to hook the elastic clamps 401 inside the groove 5.

[0030] Among them, reference Figure 1-Figure 3 As shown, multiple elastic jaws 401 and the elastic clamp 4 form an annular limiting cavity, and the width of the annular limiting cavity is larger than the core rod 2. When the elastic clamp 4 is placed on the top of the core rod 2, the multiple elastic jaws 401 and the elastic clamp 4 form an annular limiting cavity, and the core rod 2 can be wrapped by the annular limiting cavity, thereby facilitating the compression and limiting of the spring 1 on the core rod 2.

[0031] Among them, reference Figure 1-Figure 4As shown, the diameter of the core rod 2 is consistent with the inner diameter of the spring 1, and the core rod 2 and the disk 3 are in a "T" shape. When the spring 1 is put on the core rod 2, the core rod 2 and the disk 3 are arranged in a "T" shape. The disk 3 just supports the bottom end of the spring 1, and the diameter of the core rod 2 is consistent with the inner diameter of the spring 1. The inside of the spring 1 is tightly attached to the core rod 2, which plays a role in constraining the inner diameter of the spring 1, so that the straightness of the spring 1 can be maintained when the spring 1 is compressed.

[0032] Among them, reference Figure 1-Figure 6 As shown, a sleeve hole 403 is opened inside the sleeve ring 402, and the connection between the multiple elastic clamping claws 401 and the elastic clamping head 4 is an arc structure, and the sleeve hole 403 is tightly fitted with the connection between the elastic clamping claws 401 and the elastic clamping head 4.

[0033] When the ring 402 is in use, it is sleeved on the outer wall of the multiple elastic clamping jaws 401 through the internal sleeve hole 403. When the ring 402 slides up and down on the outer wall of the multiple elastic clamping jaws 401, since the connection between the multiple elastic clamping jaws 401 and the elastic clamping head 4 is arranged in an arc-shaped structure, when the ring 402 slides upward, it just limits the ring 402 to prevent the ring 402 from moving out from the top of the elastic clamping head 4, and the bottom parts of the multiple elastic clamping jaws 401 are in an open state, which can also limit the ring 402 to prevent the ring 402 from falling off the elastic clamping jaws 401.

[0034] Among them, reference Figure 7 As shown, a threaded head 6 is installed in the middle of the bottom end of the core rod 2, and a fixing screw hole 7 threadedly connected to the threaded head 6 is opened in the middle of the disk 3. When the spring 1 is compressed on the core rod 2, the core rod 2 is installed at the fixing screw hole 7 in the middle of the disk 3 through the threaded head 6. The core rod 2 is easy to remove from the disk 3, and the core rods 2 of different lengths can be replaced, and then the springs 1 of different lengths can be compressed.
