Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and in particular to a composite processing center for automotive sunroof guide rail profiles. Background Technology

[0002] Composite machining centers integrate multiple processing technologies, enabling profiles to undergo various processing steps in a single process. This significantly improves the automation level and production efficiency of complex profile processing, making them an indispensable piece of equipment in modern intelligent manufacturing.

[0003] In the profiles used in automotive sunroof guide rails, composite machining centers can complete grooving, drilling, and tapping operations on the profile surface in one go. Before processing, operators need to use fixtures to fix the profile in a specific position on the machining center. Then, the processing device approaches and contacts the profile for processing. However, during the processing, grooving and drilling operations will generate a lot of heat and debris inside the profile. If this heat is not dealt with in time, it may cause the profile to bend after processing or reduce its own material strength. The generated debris will accumulate on the profile surface during processing, affecting the processing effect. In addition, some smaller debris will also fly around and pollute the processing environment. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a composite processing center for automotive sunroof guide rail profiles, which solves the problem of heat generated inside the profile during processing that affects the processing quality, and also solves the problem of debris accumulating at the processing location and polluting the processing environment during the processing of the profile.

[0005] The technical solution of this utility model is as follows: a sunken suction chamber is set at the workpiece processing fixed position in the machining center. The side wall of the suction chamber is provided with a connection port for connecting to an air pump. A diversion chamber is set at the top of the suction chamber. A horizontally extending boss is set between the diversion chamber and the suction chamber. The diversion chamber and the suction chamber are connected by bolts through the boss. A boss is set at the top of the inner wall of the suction chamber. A collection bag is mounted on the suction chamber through the boss. The diversion chamber is a cylindrical structure with openings at both the top and bottom. A diversion plate extending upwards is provided on one side of the top of the diversion chamber. Baffle plates are evenly spaced at the top opening of the diversion chamber. Limiting rods are provided on both sides of the baffle plates. Limiting blocks for fixing guide rail profiles are slidably connected to the limiting rods. A through groove is provided on the side of the diversion chamber away from the diversion plate. Limiting bolts passing through the through groove are provided on the surface of the limiting blocks. A control knob is threadedly connected to the part of the limiting bolt outside the diversion chamber.

[0006] Furthermore, the collection bag consists of a steel ring frame at the top and a cloth bag at the bottom of the steel ring frame. A gap is left between the cloth bag part of the collection bag and the inner wall of the suction chamber to ensure that the air pump generates suction in the suction chamber so that it can pass through the cloth bag and act upward in the diversion chamber. At the same time, the gap between the cloth bag and the suction chamber allows the cloth bag to shake under the action of suction, thereby collecting the debris and impurities in the cloth bag.

[0007] Furthermore, the diversion plate is a hollow plate structure with an internal arc shape that communicates with the interior of the diversion chamber. The cavity inside the diversion plate is higher than the limiting block in the horizontal direction. The diversion plate forms an unobstructed cavity channel that allows airflow to pass smoothly, so that the airflow encounters less resistance when entering the diversion plate and generates an air curtain at the top of the limiting block.

[0008] Furthermore, the baffle plate is a number of inclined strip-shaped plate structures, and the top of the baffle plate is provided with a parallel surface. The inclined baffle plate can make the airflow more resistant to entering. At the same time, the baffle plate forms a flat grid-like platform on the surface of the diversion chamber, which prevents items from falling directly into the intake chamber during use.

[0009] Furthermore, a spring is sleeved on the outer side of the limiting rod, with both ends of the spring connected to the inner wall of the diversion chamber and the limiting block, respectively. The spring is always kept in a relaxed state to push the limiting block closer to the center position of the limiting rod. The spring pushes the limiting block to move to one side on the surface of the limiting rod, which helps to fix the profile to be processed.

[0010] Furthermore, flexible rubber strips are provided on the upper and lower sides of the inner wall of the channel. The ends of the two rubber strips contact each other to form a baffle that connects the closed channel to the diversion chamber, preventing airflow from entering the diversion chamber through the channel, enhancing the sealing effect of the diversion chamber, preventing the suction force in the diversion chamber from decreasing, and preventing the movement of the limiting bolt from being blocked.

[0011] Furthermore, the length of the through slot is adapted to the distance between the two limiting blocks under the maximum compression state of the spring.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses an air pump connected to an air intake chamber to generate suction. The suction force passes through the collection bag and is transmitted upwards. At this time, the external airflow will quickly enter the diversion chamber through the guide plate and move downwards through the collection bag. During the process of the airflow entering the guide plate, it will pass through the limiting block, so that the debris generated by the profile during processing is entrained and sucked into the diversion chamber. Finally, the debris follows the airflow into the collection bag. The debris is blocked by the collection bag, while the air can continue to flow and be discharged outwards. This allows the debris generated during the processing of the profile to be centrally processed. The operator can periodically separate the air intake chamber and the diversion chamber to remove the collection bag for cleaning.

[0013] 2. This utility model also provides a baffle plate at the top of the inner wall of the distribution chamber. The baffle plate blocks the suction force, so that most of the suction force acts on the outside air through the guide plate. A small part of the suction force is transmitted upward through the gap between the baffle plates, allowing some air to enter the distribution chamber through the guide plate. This part of the air passes through the profile between the guide plates, which increases the air velocity near the profile and helps to cool the profile, thus preventing the profile from maintaining a high temperature for a long time during the processing, which would affect the material properties.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figure 1-4 As shown, a composite machining center for automotive sunroof guide rail profiles includes a sunken suction chamber 1 located at the workpiece machining fixation position of the machining center. The side wall of the suction chamber 1 is provided with a connection port for connecting to an air pump. A diversion chamber 2 is provided at the top of the suction chamber 1. A horizontally extending boss is provided between the diversion chamber 2 and the suction chamber 1. The diversion chamber 2 and the suction chamber 1 are connected by bolts through the boss. A boss is provided at the top of the inner wall of the suction chamber 1. A collection bag 3 is mounted on the suction chamber 1 through the boss. The collection bag 3 is composed of a steel ring frame at the top and a cloth bag at the bottom of the steel ring frame. A gap is left between the cloth bag part of the collection bag 3 and the inner wall of the suction chamber 1 to ensure that the air pump generates suction in the suction chamber 1 so that it can pass through the cloth bag and act upward into the diversion chamber 2. At the same time, the gap between the cloth bag and the suction chamber 1 allows the cloth bag to shake under the action of suction, thereby collecting debris and impurities in the cloth bag. The diversion chamber 2 is a cylindrical structure with openings at both the top and bottom. A diversion plate 4 extending upwards is installed on one side of the top of the diversion chamber 2. Baffle plates 5 are evenly spaced at the top opening of the diversion chamber 2. Each baffle plate 5 is a series of inclined, strip-shaped plates with parallel surfaces at their tops. The inclined baffle plates 5 significantly resist the entry of airflow, and together they form a flat, grid-like platform on the surface of the diversion chamber 2, preventing items from falling directly into the intake chamber 1 during use. Limiting rods 6 are installed on both sides of the baffle plates 5, and limiting blocks 7 for fixing the guide rail profiles are slidably connected to the limiting rods 6. The diversion plate 4 is... The internal structure is an arc-shaped cavity plate that communicates with the interior of the diversion chamber 2. The cavity inside the diversion plate 4 is higher than the limiting block 7 in the horizontal direction. The diversion plate 4 forms an unobstructed cavity channel that allows airflow to pass smoothly. This makes the airflow encounter less resistance when entering the diversion plate 4 and creates an air curtain at the top of the limiting block 7. A spring is sleeved on the outside of the limiting rod 6. The two ends of the spring are connected to the inner wall of the diversion chamber 2 and the limiting block 7, respectively. The spring is always in a relaxed state, pushing the limiting block 7 close to the center position of the limiting rod 6. The spring pushes the limiting block 7 to move to one side on the surface of the limiting rod 6, which helps to fix the profile to be processed. A through groove 8 is provided on the side of the diversion chamber 2 away from the diversion plate 4. The length of the through groove 8 is adapted to the distance between the two limiting blocks 7 under the maximum compression state of the spring. A limiting bolt 9 passing through the through groove 8 is provided on the surface of the limiting block 7. Flexible rubber strips are provided on the upper and lower sides of the inner wall of the through groove 8. The ends of the two rubber strips contact each other to form a baffle that connects the closed through groove 8 to the diversion chamber 2, so as to prevent the airflow from entering the diversion chamber 2 through the through groove 8, enhance the sealing effect of the diversion chamber 2, prevent the suction force in the diversion chamber 2 from decreasing, and prevent the movement of the limiting bolt 9 from being blocked. The part of the limiting bolt 9 located outside the diversion chamber 2 is threadedly connected to a control knob 10.

[0018] Working principle of this utility model: First, the operator places the profile between two limiting blocks 7. The spring pushes the limiting blocks 7 to clamp the profile. Then, the operator rotates the control knob 10 to move along the limiting bolt 9 to fix the position of the limiting blocks 7, thereby limiting the processing position of the profile. Then, the operator starts processing. During the processing, the air pump is turned on simultaneously. The air pump generates suction force, which first acts on the suction chamber 1. The suction force passes through the collection bag 3 in the suction chamber 1 and acts on the diversion chamber 2. In the diversion chamber 2, the suction force is blocked by the baffle plate 5. Most of the suction force directly attracts outside air under the action of the diversion plate 4. A small part of the suction force attracts outside air through the baffle plate 5. The outside air moves inward under the suction force generated by the diversion plate 4, creating an air curtain outside the diversion plate 4. Before entering the diversion plate 4, the air curtain passes through the profile clamped and fixed by the limiting blocks 7. The debris generated by the profile during processing is carried into the diversion chamber 2 by the air curtain and finally enters the collection bag 3 with the airflow. The debris is blocked by the collection bag 3. The airflow passes through the collection bag 3 and is discharged to the outlet by the air pump to complete the collection of debris. At the same time, the airflow generated by the baffle plate 5 moves at the bottom of the profile, and the top of the profile is affected by the air curtain. At this time, there is a fast-flowing airflow on both the upper and lower sides of the profile. When the airflow comes into contact with the profile, it will absorb the heat generated inside the profile, cool down the profile, and prevent the profile from being affected by high temperature.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
