Description

Technical Field

[0001] The utility model relates to a diameter-expanding and positioning tool for automobile pipe processing. Background Art

[0002] In the field of automobile manufacturing, the processing and expansion of automobile pipe fittings is a key step. The processing and expansion of automobile pipe fittings refers to the process of expanding the diameter of automobile pipe fittings. In the field of automobile manufacturing and maintenance, it is often necessary to expand the diameter of pipe fittings to meet different connection requirements or replace the original pipe fittings.

[0003] The purpose of expanding the diameter of automobile pipe fittings is to change the inner diameter of the pipe fittings so that they can be matched with other pipe fittings or connectors. The expansion can be achieved by a variety of methods, including machining, cold heading, hot heading, etc. Among them, machining is a commonly used method, which uses appropriate tools and equipment to process the pipe fittings to expand their inner diameter.

[0004] In the traditional processing technology, due to the lack of effective limiting design, only a single type of pipe can be processed in a directional manner, and the processing flexibility is poor. Therefore, a diameter expansion positioning tool for automobile pipe processing is proposed. Utility Model Content

[0005] The utility model aims to provide a positioning tool for expanding the diameter of automobile pipes, so as to solve the problem that in the traditional processing technology mentioned in the above background technology, due to the lack of effective limit design, only a single type of pipe can be processed in a directional manner, and the processing flexibility is poor.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an automobile pipe processing expansion and positioning tool, comprising a loading plate, guide plates are arranged around the top of the loading plate, and four groups of the guide plates are connected by positioning plates;

[0007] The surface of the positioning plate is provided with two groups of channels for plugging in automobile pipe fittings, and limiters for positioning automobile pipe fittings are arranged on both sides below the channels. The loading plate is provided with an expanding cylinder for expanding the diameter of automobile pipe fittings directly below the channels.

[0008] Preferably, the limiting member comprises a connecting plate arranged at the positioning plate, the connecting plate is internally slidably connected to a limiting rod, and one end of the limiting rod is connected to the limiting plate.

[0009] Preferably, the limiting plate is arc-shaped, and the upper portion of the limiting plate is chamfered.

[0010] Preferably, a limiting block for preventing the limiting rod from deflecting is provided on the outer periphery of the limiting rod.

[0011] Preferably, a limit spring is arranged inside the connection plate, and the limit spring is located on the side of the limit block away from the limit plate.

[0012] Preferably, two groups of positioning studs cooperating with the expanding tube are arranged above the loading plate, so that the expanding tube is connected to the top of the loading plate through the positioning studs.

[0013] Preferably, a guide column is provided inside the guide plate, and the guide column is slidably connected to the positioning plate so that the positioning plate can move linearly through the guide column.

[0014] Preferably, a return spring is provided on the outer periphery of the guide column, and the return spring is located directly below the positioning plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model can adapt to the processing and expansion of automobile pipes of different models and sizes by setting the guide plate, the positioning plate and the limiter, thereby improving the processing flexibility. Compared with the traditional processing technology, which lacks an effective limiter design and can only process a single model of pipes, the processing effect is more flexible;

[0017] By setting the limiter, the accurate positioning of the pipe during the processing can be ensured, which helps to improve the processing accuracy and stability and reduce the occurrence of errors and deviations.

[0018] The tooling is equipped with an expansion cylinder for expanding the diameter of automobile pipe fittings, which is located directly below the loading plate. This allows the inner diameter of the pipe fitting to be effectively expanded during processing to meet the needs of connection or replacement. At the same time, through the setting of the positioning stud, the expansion cylinder can be connected and replaced more quickly to meet the use requirements of different expansion cylinders.

[0019] The limit piece adopts a combination design of a connecting plate, a limit rod and a limit plate. The movement of the limit rod and the fixation of the positioning plate are realized through the sliding connection between the connecting plate and the limit rod, thereby ensuring the positioning and stable processing of the pipe fitting.

[0020] The limit plate is arc-shaped and has a chamfered upper portion, so that it can better cooperate with the pipe fittings, so that during the plug-in process of the automobile pipe fittings, the limit plate can be automatically squeezed to both sides, controlling the limit plate to move in opposite directions and providing a better plug-in effect.

[0021] The limit block used to prevent the limit rod from deflecting is set on the periphery of the limit rod in the tooling, and the limit spring is set inside the connecting plate. The application of these springs can realize the automatic reset of the limit rod and the limit plate, ensuring the stability and reliability of the limit parts during the processing.

DETAILED DESCRIPTION

[0028] In order to solve the problem that in traditional processing technology, due to the lack of effective limiting design, only a single type of pipe can be processed in a directional manner, and the processing flexibility is poor, the embodiment of the utility model provides a positioning tool for expanding the diameter of automobile pipes. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in 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] See also Figure 1-5 The utility model provides a positioning tool for expanding the diameter of automobile pipes, comprising a loading plate 1, a guide plate 2 is arranged around the top of the loading plate 1, a guide column 201 is arranged inside the guide plate 2, and the guide column 201 is slidably connected with the positioning plate 3 so that the positioning plate 3 moves linearly through the guide column 201. A return spring 202 is arranged on the outer periphery of the guide column 201, and the return spring 202 is located directly below the positioning plate 3.

[0030] The four groups of guide plates 2 are connected by positioning plates 3; two groups of channels 301 for plugging automobile pipes are provided on the surface of the positioning plates 3, and the limiting members 4 for positioning automobile pipes are provided on both sides below the channels 301, and the limiting members 4 include a connecting plate 401 provided at the positioning plate 3, and the connecting plate 401 is internally slidably connected to a limiting rod 402, and one end of the limiting rod 402 is connected to a limiting plate 403. The limiting plate 403 is in an arc shape, and the upper part of the limiting plate 403 is chamfered. The outer periphery of the limiting rod 402 is provided with a limiting block 404 for preventing the limiting rod 402 from deflecting. A limiting spring 405 is provided inside the connecting plate 401, and the limiting spring 405 is located on the side of the limiting block 404 away from the limiting plate 403. The loading plate 1 is provided with an expanding cylinder 5 for expanding the diameter of automobile pipes directly below the channel 301.

[0031] Two groups of positioning studs 6 cooperating with the expanding cylinder 5 are arranged above the loading plate 1 , so that the expanding cylinder 5 is connected to the top of the loading plate 1 through the positioning studs 6 .

[0032] The working principle of the automobile pipe processing expansion positioning tool provided by the utility model is as follows: when in use, the automobile pipe to be expanded is inserted into the inside of the channel 301, so that it squeezes the limiting plate 403 along the inclined surface of the limiting plate 403, and the limiting plate 403 squeezes the limiting spring 405 located inside the connecting plate 401 through the limiting block 404 on the outer periphery of the limiting rod 402. The limiting spring 405 is forced to shrink and generate a corresponding elastic force. The elastic force acts on the outer periphery of the automobile pipe in the opposite direction through the limiting plate 403 to position the automobile pipe vertically in the channel 301 to prevent it from being offset in the channel 301. Then, the automobile pipe is inserted into the expansion tube 5 through the channel 301, and then the automobile pipe is pressed down by an external device, and at the same time, the pressure plate is driven to squeeze the reset spring 202. The reset spring 202 is compressed, and the pressure plate drives the automobile pipe to move downward to control it to expand along the expansion tube 55.

[0033] After the expansion is completed, the external device moves up, and the return spring 202 elastically stretches to control the pressure plate to move up, completing the return work of the pressure plate. When it is necessary to expand the diameter of automobile pipes of different models, the expansion cylinder 5 is rotated, unscrewed, and the expansion cylinder 5 of the matching model is replaced.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
