Description

Technical Field

[0001] The utility model relates to the technical field of junction box production, in particular to a clamping tool for junction box production. Background Art

[0002] The junction box is one of the electrical auxiliary materials. It is used as a transition at the joint of the wires (for example, the line is long, or the wire tube needs to turn a corner). The wire tube is connected to the junction box, and the wires in the wire tube are connected in the junction box, which plays a role in protecting and connecting the wires. During the production process of the junction box, it needs to be fixed by clamping tooling before welding.

[0003] The existing clamping tooling for the production of junction boxes usually uses a cylinder to clamp the two sides of the junction box to fix the junction box. However, in actual use, since the junction box is a shell structure, when the pressure of the cylinder is too high during the fixing process, the junction box is easily squeezed and deformed, resulting in the scrapping of the junction box, which makes the junction box unable to be used normally later, resulting in a waste of resources and reducing the practicality of the existing clamping tooling for the production of junction boxes.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a clamping tool for producing a junction box, comprising a base 1, a fixing component 200 for fixing the junction box is installed on the top of the base 1, an adjusting component 300 for adjusting the fixing component 200 is installed inside the base 1, and a limiting component 400 for limiting is installed inside the base 1;

[0025] Through the coordinated use of the base 1, the fixing assembly 200, the adjusting assembly 300 and the limiting assembly 400, the structure for fixing the junction box can be effectively limited during actual use, thereby effectively avoiding the junction box from being squeezed and deformed due to excessive cylinder pressure, thereby ensuring the subsequent normal and effective use of the junction box, avoiding waste of resources, and improving the practicability of the clamping tooling for the production of the junction box.

[0026] In this embodiment, the fixing assembly 200 is a structure for fixing the junction box.

[0027] like Figure 1 and Figure 2 As shown, the fixing assembly 200 includes a fixing rod 201 fixed to the top of the base 1 by bolts, and a fixing plate 202 is fixed to one end of the fixing rod 201 away from the base 1 and the top end of the connecting rod 304 .

[0028] It should be noted that the right fixing plate 202 is slidably connected to the top of the base 1, so that the right fixing plate 202 moves more stably.

[0029] In this embodiment, the adjusting component 300 is a structure for adjusting the fixing component 200 .

[0030] like Figure 1 and Figure 3As shown, the adjustment component 300 includes a motor 301 fixed on the right side of the base 1, the output shaft of the motor 301 is fixed with a first screw rod 302, the outer side of the first screw rod 302 is threadedly connected with a slider 303, the top of the slider 303 is fixed with a connecting rod 304, the top of the base 1 is provided with a connecting groove 305, and the inside of the base 1 is provided with a sliding groove 306.

[0031] It should be noted that the width of the fixing plate 202 is greater than the diameter of the connecting rod 304, which ensures that the fixing plate 202 can effectively fix the junction box while avoiding the connection groove 305 from affecting the process of fixing the junction box.

[0032] In addition, the left end of the first screw rod 302 passes through the base 1, the slide groove 306 and the slider 303 in sequence and extends to the inside of the base 1 to be rotatably connected to the base 1 through a bearing, ensuring that the first screw rod 302 can stably and effectively rotate in place.

[0033] In addition, the top of the slide groove 306 is connected to the connecting groove 305, ensuring that the slider 303 can effectively drive the connecting rod 304 to move left and right. The width of the slider 303 is equal to the width of the slide groove 306, so that the slider 303 slides in the slide groove 306 more stably.

[0034] In this embodiment, the limiting assembly 400 is a structure to prevent the junction box from being squeezed and damaged.

[0035] like Figure 1 and Figure 2 As shown, the limit assembly 400 includes a second screw 401 that rotates inside the base 1 through a bearing, and the outer ring of the bearing is fixed to the left side of the base 1 to ensure that the second screw 401 can stably and effectively rotate in place, a hand wheel 402 is fixed to the left end of the second screw 401, and an adjusting cylinder 403 is threadedly connected to the outer side of the second screw 401, a limit plate 404 is fixed to the right side of the adjusting cylinder 403, a sliding groove 405 is provided on the left side of the base 1, and limit blocks 406 are fixed on the top and bottom of the adjusting cylinder 403, and two limit grooves 407 are provided inside the base 1.

[0036] It should be noted that the opposite sides of the two limit grooves 407 are connected to the sliding groove 405 to ensure that the limit block 406 can be effectively fixed to the adjustment tube 403, and the right side of the sliding groove 405 is connected to the connecting groove 305 to ensure that the limit plate 404 can enter the connecting groove 305 to achieve the limitation of the connecting rod 304.

[0037] In addition, the adjustable distance of the limiting block 406 in the limiting groove 407 is smaller than the adjustable distance of the second screw rod 401 in the adjusting tube 403 , which effectively prevents the second screw rod 401 from falling off from the adjusting tube 403 .

[0038] The working principle of the above embodiment is:

[0039] When in use, first place the junction box that needs to be fixed on the base 1, and make its left side closely contact with the left fixed plate 202, then turn the hand wheel 402 to drive the second screw rod 401 to rotate in place, and the adjusting cylinder 403 moves left and right on the outer side of the second screw rod 401 under the action of the internal thread rotation thrust and the limiting action of the limit block 406, thereby driving the limit plate 404 to move left and right until the right side of the limit plate 404 is flush with the right side of the junction box, and then turn on the motor 301 to drive the first screw rod 302 to rotate in place, and the slider 303 moves left and right on the outer side of the first screw rod 302 under the action of the internal thread rotation thrust, thereby driving the right fixed plate 202 to move left and right through the connecting rod 304, so that the junction box is effectively fixed by the two fixed plates 202, and under the action of the limit plate 404, the junction box can be effectively prevented from being squeezed and deformed when the right fixed plate 202 moves to the left.

[0040] Compared with the prior art, the clamping tool for producing the junction box, through the coordinated use of the base 1, the fixing component 200, the adjusting component 300 and the limiting component 400, can effectively limit the structure for fixing the junction box during actual use, thereby effectively avoiding the situation where the junction box is squeezed and deformed due to excessive cylinder pressure, thereby ensuring the subsequent normal and effective use of the junction box, avoiding waste of resources, improving the practicability of the clamping tool for producing the junction box, and solving the problem of low practicability of the existing clamping tool for producing the junction box.

[0041] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of an external power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
