Description

Technical Field

[0001] This utility model relates to the field of automotive fixture manufacturing technology, specifically a fixed adsorption component for automotive fixture manufacturing. Background Technology

[0002] Automotive fixtures are devices used in the automotive manufacturing process to fix and position automotive parts to ensure that the parts maintain the correct position and orientation during processing, welding, assembly, or inspection. Positioning elements are one of the core components of the fixture, and their main function is to determine the accurate position of the automotive parts in the fixture. By contacting specific surfaces or features of the parts, they restrict the degrees of freedom of the parts, thereby ensuring the accuracy of the parts' position during processing, welding, assembly, or inspection.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. During automobile production, the production process may change. For example, the initial process plan might be to perform overall adsorption processing on a certain part of the car body. However, with technological improvements or feedback on quality issues, it may be necessary to focus on adsorption on specific parts of the component or apply different adsorption forces. If the suction cup spacing cannot be adjusted, the adsorption strategy cannot be flexibly changed. For small-batch trial production or customized production of some automotive parts, their size and shape differ from conventional products. In this case, fixtures that cannot adjust the suction cup spacing are unlikely to meet special production needs, requiring the redesign and manufacture of new fixtures, which increases production costs and time. 2. In automobile production, the processing and assembly precision requirements for parts are very high. Due to the large number of car models and the wide variety of shapes and sizes of body parts, for example, the side panels of small cars and large SUVs are very different in size, curvature and surface complexity. If the suction cup of the fixture cannot adjust the movement distance, the position of the suction cup fixed by screws will be difficult to adapt to these differences. For different car parts, such as doors, hoods, trunk lids, etc., their shapes and adsorption requirements are also different. The inability to flexibly adjust the position of the suction cup will cause the fixture to not fit these parts well. It is necessary to make special fixtures for different car models and parts, which increases the manufacturing cost and storage cost of the fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed adsorption assembly for automotive fixture production, solving the problem mentioned in the background art where the suction cup spacing cannot be adjusted, thus hindering flexible changes in adsorption strategies. For small-batch trial production or customized production of some automotive parts, whose dimensions and shapes differ from conventional products, fixtures with adjustable suction cup spacing struggle to meet specific production needs. To achieve the above objective, this utility model provides the following technical solution: a fixed adsorption assembly for automotive fixture production, comprising a mounting plate, a drive cylinder positioned in front of the mounting plate, and a support plate mounted on the lower output shaft of the drive cylinder via screws;

[0005] The motor housing is mounted on the front of the mounting plate by screws. The output shaft on one side of the motor is connected to a first threaded screw by screws. A slider is connected to the external thread of the first threaded screw. A slide rail is mounted on the inside of the mounting plate by screws. A slide rod is mounted on the inside of the slide rail by screws. A cylinder controller is mounted on the front of the slider by screws.

[0006] A second threaded rod is fitted inside the support plate. A fixing buckle is threaded onto the outer wall of the second threaded rod. A connecting plate is welded below the second threaded rod. A fixing plate is welded below the connecting plate. A vortex vacuum pump and a solenoid valve are respectively installed on the top of the fixing plate by screws. A solenoid valve is provided on one side of the vortex vacuum pump. A three-way adapter is inserted into the bottom of the fixing plate. A vacuum suction cup is connected to one side of the three-way adapter through a pipe.

[0007] More preferably, the first threaded screw forms a rotating structure via a motor, and the internal thread of the slider is consistent with the external thread structure size of the first threaded screw, and the slider forms a horizontal sliding structure via the first threaded screw.

[0008] More preferably, the slide rail has a slide rod and a first threaded screw vertically distributed inside, and there is a slide rod above and below the first threaded screw.

[0009] More preferably, the external thread structure dimensions of the second threaded screw are consistent with the internal structure dimensions of the fixing buckle.

[0010] More preferably, one side of the three-way adapter is provided with several pipe connections, and the three-way adapter is connected to the vortex vacuum pump and the vortex vacuum pump is connected to the solenoid valve. Furthermore, one side of the three-way adapter is connected to the vacuum suction cup, and the other side of the three-way adapter is connected to another vacuum suction cup.

[0011] More preferably, the support plate is configured as a vertical sliding structure by a driving cylinder.

[0012] More preferably, the cylinder controller and the drive cylinder are connected by a cable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, adjusting the spacing of the vacuum suction cups can concentrate the suction force on the localized areas that require special attention, without having to redesign the entire fixture system. This improves the flexibility and adaptability of production. The fixture can adjust the spacing of the vacuum suction cups according to the specific size and shape of the parts, ensuring efficient processing and assembly even in small-batch or customized production. This avoids the increased production and time costs associated with redesigning and manufacturing new fixtures.

[0015] In this invention, the motor drives the first threaded screw to adjust the horizontal position, the drive cylinder drives the support plate to adjust the vertical height, and the second threaded screw cooperates with the fixing buckle to adjust the suction cup spacing. These functions combine to enable the fixture to accurately position and adsorb parts of different sizes and shapes during automobile production. For example, in the assembly of automobile engines, it is necessary to accurately assemble parts of various shapes and sizes. By precisely adjusting the position of the vacuum suction cup, it can be ensured that each part can be accurately adsorbed and positioned, improving assembly accuracy and efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a fixed adsorption assembly for automobile clamp production, including a mounting plate 1, a drive cylinder 3 in front of the mounting plate 1, and a support plate 2 mounted on the lower output shaft of the drive cylinder 3 by screws.

[0023] The housing of motor 101 is mounted on the front of the mounting plate 1 by screws. The output shaft on one side of motor 101 is connected to a first threaded screw 103 by screws. The external thread of the first threaded screw 103 is connected to a slider 105. The slide rail 102 is mounted inside the mounting plate 1 by screws. The slide rod 104 is mounted inside the slide rail 102 by screws. The cylinder controller 106 is mounted on the front of slider 105 by screws.

[0024] A second threaded rod 201 is fitted inside the support plate 2. A fixing buckle 202 is threadedly connected to the outer wall of the second threaded rod 201. A connecting plate 203 is welded below the second threaded rod 201. A fixing plate 205 is welded below the connecting plate 203. A vortex vacuum pump 204 and a solenoid valve 208 are respectively installed on the top of the fixing plate 205 by screws. A solenoid valve 208 is provided on one side of the vortex vacuum pump 204. A three-way adapter 206 is inserted into the bottom of the fixing plate 205. A vacuum suction cup 207 is connected to one side of the three-way adapter 206 through a pipe.

[0025] In this embodiment, as Figure 3 As shown, the first threaded screw 103 forms a rotating structure through the motor 101, and the internal thread of the slider 105 is consistent with the external thread structure of the first threaded screw 103. The slider 105 forms a horizontal sliding structure through the first threaded screw 103. The motor 101 serves as a power source, driving the first threaded screw 103 to rotate through its output shaft. Since the slider 105 matches the thread structure of the first threaded screw 103, it can achieve horizontal sliding when the screw rotates. The horizontal position of the cylinder controller 106 provides the basis, thereby indirectly affecting the horizontal operating accuracy of the entire device.

[0026] In this embodiment, as Figure 3As shown, the slide rail 102 has a slide rod 104 and a first threaded screw 103 vertically distributed inside, and there is a slide rod 104 above and below the first threaded screw 103 respectively; the existence of the slide rod 104 is mainly to provide stable guidance for the horizontal sliding of the slider 105, prevent the slider 105 from shaking or deviating during the sliding process, and ensure the smoothness and accuracy of the horizontal movement of the slider 105.

[0027] In this embodiment, as Figure 4 As shown, the external thread structure dimensions of the second threaded screw 201 are consistent with the internal structure dimensions of the fixing buckle 202; rotating the fixing buckle 202 allows it to move on the second threaded screw 201, thereby driving the connected components to move and achieving the purpose of adjusting the spacing of the vacuum suction cup 207.

[0028] In this embodiment, as Figure 4 As shown, one side of the three-way adapter 206 is provided with several pipe connections, and the three-way adapter 206 is connected to the vortex vacuum pump 204 and the vortex vacuum pump 204 is connected to the solenoid valve 208. Furthermore, one side connector of the three-way adapter 206 is connected to the vacuum suction cup 207, and the other side connector of the three-way adapter 206 is connected to another vacuum suction cup 207. The three-way adapter 206 is the hub of the entire gas circuit system, connecting various components and allowing gas to flow between them. It provides the necessary gas passage for the vacuum suction cup 207 to pick up items. By controlling the vortex vacuum pump 204 and the solenoid valve 208, a low-pressure environment can be formed inside the vacuum suction cup 207, thereby realizing the function of picking up items.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the support plate 2 forms a vertical sliding structure through the drive cylinder 3; the extension and retraction of the drive cylinder 3 can drive the support plate 2 to move up and down, thereby adjusting the height of the vacuum suction cup 207 to meet the needs of car clamps at different heights.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the cylinder controller 106 is connected to the drive cylinder 3 by a cable; the cylinder controller 106 can send control signals to the drive cylinder 3, thereby precisely controlling the action of the drive cylinder 3, and thus achieving precise control of the vertical movement of the support plate 2.

[0031] The method of use and advantages of this utility model: The fixed adsorption assembly for automobile clamp production works as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the motor 101 on one side of the slide rail 102 first operates, and the output shaft on one side of the motor 101 drives the first threaded screw 103 to rotate. Since the internal thread structure dimensions of the first threaded screw 103 and the slider 105 are consistent, it plays a guiding role, allowing the slider 105 to move horizontally smoothly on the first threaded screw 103 and the slide rod 104. The cylinder controller 106 controls the downward movement of the support plate 2 connected to the drive cylinder 3, which facilitates the adjustment of the distance and height of the vacuum suction cup 207 for the production of automotive fixtures. The vacuum suction cup 207 picks up the item via the solenoid valve 208 and the vortex vacuum pump 204. When an item needs to be picked up, the vortex vacuum pump 204 is started. After the vortex vacuum pump 204 starts working, it creates a low-pressure area inside. It starts to suck up gas through the pipe connected to the solenoid valve 208 and the vacuum suction cup 207 via the three-way adapter 206. However, since the solenoid valve 208 is still in the closed state at this time, the air pressure inside the vacuum suction cup 207 will not be affected temporarily. Then, the solenoid valve 208 is opened. The solenoid valve 208 acts like a valve; when it opens, the low-pressure area generated by the vortex vacuum pump 204 connects with the space inside the vacuum suction cup 207. This allows the vortex vacuum pump 204 to draw away the gas inside the vacuum suction cup 207, causing the internal pressure to drop. As more gas is drawn away, the internal pressure decreases further. When the internal pressure of the vacuum suction cup 207 falls below the external atmospheric pressure, a pressure difference is formed between the suction cup and the surface of the object to be suctioned. A pressure difference exists, and under this pressure difference, the external atmospheric pressure will press the object tightly against the vacuum suction cup 207, thereby achieving the purpose of picking up the object. Rotating the fixing buckle 202 clockwise will disengage the fixing buckle 202 from the second threaded screw 201, and the components connected to the moving connecting plate 203 will be adjusted to adjust the distance between the vacuum suction cups 207. Then, by rotating the fixing buckle 202 counterclockwise, the fixing buckle 202 will be threaded and fixed to the second threaded screw 201. The fixing buckle 202 will rotate to the top of the support plate 2 for fixing.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
