Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture for processing water pipe openings. Background Technology

[0002] During the processing of water pipe ends, several functional holes are drilled and connecting posts are cut into the side wall of the pipe opening. Therefore, it is necessary to fix it during processing. Existing fixing fixtures use three different jaws to clamp the bottom of the pipe opening, such as... Figure 1 As shown, the fixed point is at the bottom of the pipe opening. When machining the side, it is pressed down, which causes a slight displacement of the pipe opening during the machining process, resulting in deviations in the machining. Especially in the machining of pipe openings with a large allowance, due to the relatively long machining time, tool marks are easily generated at the entry and exit positions of the milling cutter, affecting product quality. Therefore, this technical solution is proposed to improve the process. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology in that the water pipe opening is not fixed stably during the processing, which affects the product quality, and to provide a fixture for processing water pipe openings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fixture for processing water pipe openings, comprising a mounting plate mounted on a machine tool, a connecting plate provided on one side of the mounting plate, a telescopic device provided in the middle of the connecting plate, a fixing plate for positioning the pipe opening body provided on the working surface of the connecting plate, a pressing block provided above the fixing plate, and the bottom of the pressing block being hinged to the telescopic device.

[0005] Furthermore, the telescopic device is one of a telescopic rod or a cylinder.

[0006] Furthermore, the crimping block is a right-angled block, the corner of the crimping block is hinged to the upper part of the connecting plate, and the top of the crimping block is provided with a pressing block for abutting against the pipe body.

[0007] Furthermore, the top of the pressing block is provided with an installation groove, and the middle position of the pressing block is provided with a protrusion that connects to the inside of the installation groove.

[0008] Furthermore, the mounting groove is provided with a rotating shaft and a protrusion for connection.

[0009] Furthermore, a counterweight block is provided on the upper part of the connecting plate, which is connected to the pressing block.

[0010] Furthermore, the fixing plate is provided with a plurality of positioning holes, and the positioning holes are provided with positioning pins that are adapted to the pipe body.

[0011] The beneficial effects of this utility model embodiment are as follows: A pressing block is provided above the fixing plate. The pressing block is used to further press and fix the pipe body. When the telescopic device is activated, it will drive the pressing block to rotate around the hinge point, so that the top of the pressing block can open and close on the vertical plane, providing space for pressing the pipe body. Compared with the existing side processing of the pipe, the X-axis force of the lathe is converted into Z-axis force to press the workpiece, which increases the force-bearing surface during pressing, improves the stability during fixing, and produces better roundness by using a lathe tool without tool marks, resulting in reliable product quality.

[0017] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] See Figures 2 to 4 This utility model discloses a fixture for processing water pipe ends, including a mounting plate 1 mounted on a machine tool. The fixture mainly comprises the mounting plate 1, a connecting plate 2, a telescopic device, a fixing plate 6, and a pressing block 4, among other key components. The mounting plate 1 serves as the mounting base for the entire fixture, providing stable support for subsequent components and ensuring stability during processing. The connecting plate 2 is located on one side of the mounting plate 1, connecting and supporting other components. A telescopic device is installed in the middle of the connecting plate 2. The telescopic device can be either a telescopic rod or a cylinder; the specific choice depends on actual processing requirements, cost, and usage. The telescopic device provides power support for the movement of the pressing block 4. By controlling the telescopic device, the clamping and release of the pipe end body 5 are achieved. When used with the machine tool, this significantly improves processing efficiency.

[0019] A fixing plate 6 is provided on the working surface of the connecting plate 2. The fixing plate 6 is horizontally positioned, and a working space is provided at the lower part of the connecting plate 2 for positioning the pipe body 5. To ensure that the pipe body 5 can be accurately and stably positioned on the fixing plate 6, the fixing plate 6 is provided with multiple positioning holes. The positioning holes are provided with positioning pins 601 that are adapted to the pipe body 5. When placing the pipe body 5, the corresponding holes on the pipe body 5 are engaged with the positioning pins 601 to achieve the initial positioning of the pipe body 5. A pressing block 4 is provided above the fixing plate 6. The pressing block 4 is used to further press and fix the pipe body 5. The pressing block 4 is a right-angled block, which is installed vertically. Its corner is hinged to the upper part of the connecting plate 2. This hinged method allows the pressing block 4 to rotate around the hinge point. The bottom of the crimping block 4 is hinged to the telescopic device. When the telescopic device moves, it will drive the crimping block 4 to rotate around the hinge point, so that the top of the crimping block 4 can open and close on the vertical plane, providing space for the crimping of the pipe body 5. Compared with the existing side processing of the pipe, the X-axis force of the lathe is converted into the Z-axis force to press the workpiece, which increases the force-bearing surface during crimping, improves the stability during fixing, and produces better roundness by using a lathe tool without tool marks, resulting in reliable product quality.

[0020] The top of the crimping block 4 is provided with a crimping block 401 for abutting against the pipe body 5. In order to facilitate the installation and replacement of the crimping block 401, the top of the crimping block 4 is provided with an installation groove, and a protrusion is provided in the middle position of the crimping block 401. The protrusion is connected to the inside of the installation groove. A rotating shaft is provided inside the installation groove, and the protrusion is connected to the installation groove through the rotating shaft. In this way, the crimping block 401 can rotate within a certain range, which can adapt to the situation where the parallelism between the pressing surface and the supporting surface is not good, so as to better adapt to the shape and position of the pipe body 5 and ensure the pressing effect.

[0021] In addition, in order to make the crimping block 4 more stable when crimping the pipe body 5, a counterweight block 3 is provided on the upper part of the connecting plate 2 and connected to the crimping block 4. The counterweight block 3 raises the connection point of the crimping block 4, which can increase the opening and closing space of the crimping block 4, reduce the possibility of displacement of the pipe body 5 due to external force during processing, and improve the stability of installation.

[0022] In practical use, the pipe end body 5 is first placed on the fixed plate 6 and initially positioned using the positioning pin 601. Then, the telescopic device is activated, or the lathe clamping button lever is activated to pull the pressure plate downwards to press the pipe end body 5. The telescopic device drives the crimping block 4 to rotate around the hinge point, causing the pressure block 401 on the top of the crimping block 4 to abut against the pipe end body 5, thus achieving the pressing and fixing of the pipe end body 5. During processing, because the pipe end body 5 is stably fixed on the fixture, it will not shift, thereby effectively avoiding processing deviations and tool marks, and improving product quality. After processing is completed, the telescopic device extends to release the crimping block 4 from the pipe end body 5, allowing the processed pipe end body 5 to be removed for repeated processing, improving the quality and efficiency of water pipe end processing.
