Description

Technical Field

[0001] The utility model relates to the production and processing field of current transformers, and more specifically to a copper column crimping fixing tool and a copper column crimping set. Background Art

[0002] Figure 1 It is a structural schematic diagram of a copper column and a shell that need to be crimped; it includes a plastic shell and a copper column. During the processing, the copper column needs to be pressed into the first mounting hole of the plastic shell, and the bottom surface of the pressed copper column protrudes a certain distance from the shell plane at the bottom of the plastic shell.

[0003] Figure 2 Schematic diagram of the structure of the copper column crimping and fixing tool in the prior art. Figure 2 As shown, it includes two different types of fixing fixtures 400, and a groove of a certain width is opened in the middle of the fixing fixture. The width is greater than the diameter of the copper column, and the depth is set according to the distance that the bottom of the copper column needs to protrude from the shell plane. When in use, align the first mounting hole of the plastic shell with the groove of the fixture, place the plastic shell on the fixture, then place the copper column into the first mounting hole, and then press down to crimp the copper column. At present, the clamping operation is also completed by manual rotation (not shown in the figure).

[0004] In the above operation, the method of aligning the first mounting hole and the groove of the shell by the operator visually is prone to human error and causes placement deviation, which ultimately makes it impossible to ensure the required distance of the protruding shell plane or the flatness of the copper column after crimping. In addition, manual crimping is labor-intensive and has a poor clamping effect. Utility Model Content

[0016] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is further described in detail with examples below.

[0017] Figure 3 A schematic diagram of a copper column crimping and fixing tool structure according to an embodiment of the utility model is shown;

[0018] like Figure 3 As shown, the copper column crimping fixing tool 100 is suitable for fixing the shell 2 and the copper column 1 in the first mounting hole 11 of the shell 2 when the copper column 1 is pressed into the shell 2, and includes a first groove body 11 for fixing the shell 2, the first groove body 11 is located in a horizontally arranged bottom plate 22, and the bottom plate 22 is provided with a bottom plate 22 mounting hole to be fixed on a horizontal surface; the first groove body 11 has a depth adapted to the height of the shell 2, and a second groove body 23 is also arranged in the middle of the first groove body 11, the second groove body 23 is a groove body sunk downward from the surface of the first groove body 11, and the diameter of the second groove body 23 is adapted to the diameter of the copper column 1.

[0019] Specifically, the bottom plate 22 can be made of a wooden structure and can be composed of multiple layers. The first slot body 11 and the second slot body 23 are adapted to the shape of the housing 2 and the shape of the first mounting hole 11, and are both circular. The second slot body 23 is adapted to the position of the first mounting hole 11 in the housing 2, and is correspondingly arranged inside the first slot body 11, for example, at the center of the first slot body 11. The second slot body 23 is arranged to be a slot body that sinks downward from the surface of the first slot body 11, so as to cooperate with the copper column 1 to be pressed and protrude from the bottom surface of the housing 2.

[0020] Furthermore, the depth of the second groove body 23 is adapted to the preset height of the copper pillar 1 protruding from the first mounting hole 11. Based on this, the copper pillar 1 can be pressed to a preset position to meet the process requirements.

[0021] Furthermore, the preset protrusion height is 1 mm to 2 mm, preferably 1.5 mm.

[0022] Furthermore, the housing 2 is a housing of a current transformer, and is applied to the production and manufacturing of current transformers and devices including current transformers, such as battery devices.

[0023] Based on the copper column crimping fixing tooling of the above embodiment, the housing and the copper column are limited by cleverly setting the grooves of different depths, and the depth of the second groove is accurately set to meet the process requirements of copper column installation. The tooling is simple and convenient, making the copper column crimping process easy to operate and the crimping quality better.

[0024] According to the second aspect of the utility model, a copper column crimping kit is also provided, including the copper column crimping fixing tool 100 and the copper column pressing tool 200 of the above embodiment, which are used together to complete the pressing process of the copper column 1; wherein the copper column pressing tool 200 is suitable for pressing the copper column 1 into the first mounting hole 11 of the shell 2.

[0025] Figure 4 This is a structural schematic diagram of a copper column pressing tool according to an embodiment of the utility model;

[0026] like Figure 4 As shown, the copper column pressing tool 200 includes a base 31, an actuator and a height adjustment mechanism. The actuator is arranged above the base 31 and is suitable for pressing down the copper column 1 in the copper column crimping and fixing tool 100; the height adjustment mechanism is connected to the actuator and is suitable for adjusting the upper and lower positions of the actuator.

[0027] Specifically, the copper column pressing tool 200 can be made of stainless steel, with two columns on the base 31, a horizontal fixed plate is arranged between the two columns above the base 31, and at least a part of the actuator and the height adjustment mechanism are installed on the horizontal fixed plate. Since the actuator has a certain operating stroke, the height adjustment mechanism is additionally arranged so that the actuator can meet the requirements of pressing the copper column 1. The horizontal fixed plate can be adjusted up and down by operating the height adjustment mechanism to drive the actuator to move up and down.

[0028] Furthermore, the copper column crimping fixture 100 is detachably mounted on the base 31. For example, it is mounted by bolt fastening.

[0029] Furthermore, the height adjustment mechanism is, for example, a screw rod.

[0030] Furthermore, the actuator includes a cylinder 33 and a contact member 35 at the bottom of the cylinder 33. The cylinder 33 can be driven by a foot, and a foot switch (not shown in the drawings) is provided to input an air source to the cylinder 33, so that the cylinder 33 drives the contact member 35 to move up and down.

[0031] Preferably, the bottom surface of the contact member 35 is adapted to the surface of the copper column 1 .

[0032] Based on the copper column pressing tooling of the above embodiment, the contact piece driven by the cylinder makes the downward pressure greater, and a height adjustment mechanism is practical, which is convenient for processing copper column shells of different models and parameters, and has stronger applicability. The tooling saves manpower and thus improves efficiency.

[0033] Furthermore, the height adjustment mechanism includes a rotating screw 37 and an adjustment handle 39 . The adjustment handle 39 is threadedly connected to the rotating screw 37 , and one end of the rotating screw 37 is connected to the cylinder 33 .

[0034] Based on this embodiment, the height adjustment mechanism uses a rotating screw 37 to drive the horizontal fixing plate to move up and down, and the adjustment handle 39 can achieve the up and down displacement of the rotating screw 37 by being threadedly connected to the rotating screw 37.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
