Description

Technical Field

[0001] The utility model relates to a pressing device, in particular to a device for controlling the pressing depth of a water pipe of an electric control box. Background Art

[0002] The existing water pipe pressing uses oil cylinder limit or electric cylinder parameter setting to control the depth. The depth requirement reference value or pressing to the limit position, the pressing tolerance is ±0.5mm. However, the pressing depth tolerance of the water pipe pressing of the electric control box is ±0.2mm. The pressing depth is the distance from the water pipe orifice surface to the convex table surface. There are tolerances between the positioning holes and the water pipe holes of the product, which will affect the pressing depth. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above deficiencies and provide a device for controlling the pressing depth of a water pipe of an electric control box.

[0004] The purpose of the utility model is realized by the following technical scheme: A device for controlling the pressing depth of a water pipe of an electric control box includes an electric cylinder, a displacement sensor and a slider. The electric cylinder is fixedly installed on a base. The right end of the slider is provided with the electric cylinder, and the electric cylinder drives the slider to move left and right. The left end of the slider is installed with a pressing head, and a water pipe is clamped in the pressing head. Detection rods are installed on both sides of the pressing head, and the detection rods are fixedly installed on the slider. There are pipe holes on the workpiece, and reference convex platforms are arranged on both sides of the pipe holes.

[0005] A further improvement of the utility model lies in that: a displacement sensor is installed on the slider.

[0006] The utility model has the following advantages compared with the prior art:

[0007] The utility model uses an electric cylinder for pressing, eliminates the problem of inconsistent depth reference during pressing, improves the quality of the product, reduces unqualified pressed products, and indirectly reduces costs. Description of the Drawings

[0010] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. The elements and features described in one embodiment of the present utility model can be combined with the elements and features shown in one or more other embodiments. It should be noted that, for the sake of clarity, the representation and description of components and processes that are irrelevant to the present utility model and known to those of ordinary skill in the art are omitted in the description. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0011] A device for controlling the press-fitting depth of a water pipe in an electric control box, comprising an electric cylinder 1, a displacement sensor 2 and a slider 3. The displacement sensor 2 is installed on the slider 3. The electric cylinder 1 is fixedly installed on a base 9. The right end of the slider 3 is provided with the electric cylinder 1, and the electric cylinder 1 drives the slider 3 to move left and right. A pressing head 4 is installed at the left end of the slider 3. A water pipe 8 is clamped in the pressing head 4. Detection rods 5 are installed on both sides of the pressing head 4. The detection rods 5 are fixedly installed on the slider 3. A pipe hole 7 is provided on a workpiece, and reference bosses 6 are provided on both sides of the pipe hole 7.

[0012] The present utility model calculates the feedback value by detecting the same reference depth of the product, and performs press-fitting according to the calculated value by the electric cylinder. The press-fitting depth is calculated according to the median value, which improves the quality of the product, reduces unqualified press-fitted products, and indirectly reduces costs.

[0013] Working principle:

[0014] After the electric cylinder 1 moves to the set press-fitting position through the base 9, the telescopic rod of the electric cylinder 1 extends and pushes the slider 3 to move left. When the detection rod 5 contacts the reference boss 6, the detection rod 5 starts to move right. At the same time, the displacement sensor 2 detects and outputs a value. When the pressing head 4 contacts the pipe orifice 7, it is necessary to calculate how much further distance is required to reach the drawing requirement for the distance from the surface of the pipe orifice 8 to the surface of the reference boss 6. The electric cylinder 1 advances again according to the calculated value. After the press-fitting is in place, all mechanisms return to their original positions. At this time, the press-fitting depth is infinitely close to the median value required by the drawing.

[0015] Finally, it should be noted that although the present utility model and its advantages have been described in detail above, it should be understood that various changes, substitutions and transformations can be made without departing from the spirit and scope of the present utility model as defined by the appended claims. Moreover, the scope of the present utility model is not limited to the specific embodiments of the processes, devices, means, methods and steps described in the specification. Those of ordinary skill in the art will readily understand from the disclosure of the present utility model that processes, devices, means, methods or steps that perform substantially the same functions or achieve substantially the same results as the corresponding embodiments described herein can be used according to the present utility model, both existing and those to be developed in the future. Therefore, the appended claims are intended to cover such processes, devices, means, methods or steps within their scope.
