Description

Technical Field

[0001] The utility model belongs to the technical field of tooling, and in particular relates to a hanging spring clamping tooling for a circuit breaker energy storage spring. Background Art

[0002] High-voltage circuit breakers are responsible for the protection and control of overload, short circuit and other electrical equipment in high-voltage power supply and distribution systems. When the circuit breaker is working, it mainly relies on the contact and separation of the moving and static contacts of the arc extinguishing chamber to complete the closing and opening operations. The task of the circuit breaker energy storage spring is to drive the mechanism to move and successfully close the circuit breaker. Whether the material of the energy storage spring and the closing work are reasonable directly affect the mechanical properties and service life of the circuit breaker. The defects of the existing outdoor circuit breaker energy storage spring assembly: 1. Low assembly efficiency: When assembling the existing energy storage spring, it only depends on the employees to manually swing the vise in and clamp it, and a lot of time is wasted on this action during assembly. 2. Poor clamping: As the employees hang up the energy storage spring hanging plate, the energy storage spring will become loose under the action of force. 3. The size of the existing tooling cannot be adjusted: The existing fixture is a spring, a fixture, which greatly increases the cost of use.

[0003] Based on the above problems, it is necessary to propose improvements. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0030] See also Figure 1-12 , describe the embodiments of the present utility model in detail.

[0031] Example: Spring clamping fixture for circuit breaker energy storage spring, see Figure 4-6 As shown, it includes a base 1, the base 1 includes a base platform 1-1, and a cylinder mounting vertical plate 1-2 is vertically arranged on the upper part of the base platform 1-1; Figure 1-3 As shown, a cylinder 5 is fixed on the cylinder mounting vertical plate 1-2; a mounting platform 2 is fixed on one side of the upper part of the base platform 1-1, a static chuck 3 is fixed on the upper right part of the mounting platform 2, and a dynamic chuck structure 4 is provided on the upper left part of the mounting platform 2. The dynamic chuck structure 4 is fixedly connected to the piston end of the cylinder 5 and moves horizontally left and right with the piston, and the clamping surface of the dynamic chuck structure 4 is opposite to the clamping surface of the static chuck 3. The cylinder is a heavy-duty cylinder.

[0032] In this embodiment, the traditional hand-cranked clamp is replaced with a pneumatic clamp, and the chuck is replaced with a static chuck and a dynamic chuck structure with adjustable clamping spacing. The cylinder in the tooling is connected to an air pump, and the piston of the cylinder is extended or retracted through the cylinder control device to achieve the purpose of clamping or loosening. The tooling clamp effectively improves the efficiency and quality of assembly, effectively reduces the assembly strength, and ensures that the mechanical characteristics of the circuit breaker are within a reasonable range.

[0033] In a specific embodiment, see Figure 7-10 As shown, the dynamic chuck structure 4 includes a dynamic chuck 4-1, and a dynamic chuck V-shaped clamping groove 4-2 is provided on the clamping surface of the dynamic chuck 4-1 opposite to the static chuck 3, and a static chuck V-shaped clamping groove 3-1 is provided on the clamping surface of the static chuck 3 opposite to the dynamic chuck structure 4.

[0034] By means of the above-mentioned implementation structure, a V-shaped groove is made, which can increase the contact area between the clamping surface and the spring. When the tooling is in use, the spring can be clamped better and will not move with the movement of the spring hanging plate.

[0035] In a specific embodiment, see Figure 11-12 As shown, V-shaped rubber pads 6 are provided in the dynamic chuck V-shaped groove 4-2 and the static chuck V-shaped groove 3-1, and dynamic chuck grooves 4-3 for clamping the corresponding V-shaped rubber pads 6 are formed on both sides of the dynamic chuck V-shaped groove 4-2, and static chuck grooves 3-2 for clamping the corresponding V-shaped rubber pads 6 are formed on both sides of the static chuck V-shaped groove 3-1.

[0036] Through the above implementation, by adding V-shaped rubber pads to the static chuck and the dynamic chuck structure, the friction between the spring and the chuck is increased, ensuring stable and reliable installation.

[0037] In a specific embodiment, a static clamp mounting plate 2-1 is vertically fixed to the upper right side of the mounting platform 2, and the static clamp 3 is fixed to the left side of the static clamp mounting plate 2-1 by bolts, ensuring that the static clamp is reliably installed and fixed, and the structure is simple and convenient.

[0038] In a specific embodiment, two horizontally arranged guide rods 2-2 are fixedly connected to the left side of the static chuck mounting plate 2-1, static chuck U-shaped guide grooves 3-3 adapted to the guide rods 2-2 are provided on both sides of the static chuck 3, and dynamic chuck U-shaped guide grooves 4-5 adapted to the guide rods 2-2 are provided on both sides of the dynamic chuck 4-1.

[0039] Through the above structure, by setting the guide rod 2-2, the movable clamp 4-1 cooperates with the guide rod 2-2, and the movable clamp 4-1 is guided by the guide rod during the left and right movement to ensure linear movement.

[0040] In a specific embodiment, a C-shaped connecting plate 4-4 is fixedly provided at the rear of the dynamic chuck 4-1, and the C-shaped connecting plate 4-4 is fixedly connected to the piston end of the cylinder 5 by bolts. The two sides of the cylinder mounting vertical plate 1-2 are reinforced with the base platform 1-1 by rib plates 1-3, so that the connection of the cylinder mounting vertical plate is stable and firm.

[0041] When this fixture is used, the cylinder in the tooling is connected to the air pump, and the piston of the cylinder is extended or retracted through the cylinder control device to achieve the movement of clamping or loosening. When assembling the energy storage spring, put the spring in the middle of the chuck, press the cylinder control button, the cylinder extends, the chuck clamps the spring, and then rotate the spring hanging plate into the spring, press the cylinder control button again, turn the spring in the direction, and assemble the spring hanging plate. After assembly, pay attention to check the direction of the hanging plate. This is the assembly process of the energy storage spring.
