Abstract
Description
Technical Field
[0001] This invention relates to the field of combined multifunctional metal processing equipment, specifically to an integrated grinding and drilling device for aluminum alloy flanges. Background Technology
[0002] Aluminum alloy flanges are key components in pipe connections and equipment sealing, and are widely used in various industrial fields. To ensure the assembly accuracy and sealing performance of flanges, it is usually necessary to drill precise holes on their end faces or circumferences, and to grind and deburr the holes and edges to eliminate processing stress concentration and improve surface finish. In existing conventional production processes, the drilling and grinding processes for flange parts are usually performed separately. First, drilling is done on a drilling machine or machining center. Then, the workpiece is unloaded from the fixture and transferred to the grinding station. Next, manual hand-held pneumatic or electric grinding tools are used to chamfer and remove burrs from the hole openings, or a dedicated grinding machine is used for secondary clamping and processing. These processing methods have the following main technical drawbacks in practical applications: First, the dispersed production process leads to low production efficiency. Workpieces need to be frequently transferred between different machines, which not only consumes a lot of production auxiliary time but also increases the logistics costs and equipment footprint of the workshop. Second, multiple clamping severely affects machining accuracy. After drilling, flange parts are re-clamped for grinding, which inevitably introduces secondary positioning errors, resulting in uneven grinding allowance and even damage to the machined hole wall, making it difficult to guarantee the coaxiality requirements of the hole and the grinding chamfer. Third, manual grinding is labor-intensive and inconsistent. Relying on manual operation not only requires high technical proficiency from operators, but also makes the grinding quality highly susceptible to fluctuations due to human factors, making it difficult to meet the needs of mass standardized production of precision parts. Therefore, based on the aforementioned shortcomings in the existing technology, there is an urgent need to develop an automated composite machining device that can integrate drilling and grinding functions, reduce the number of workpiece clamping operations, and improve machining accuracy and efficiency.

The switching mechanism 4 includes a switching mounting base 4-1, a switching bracket 4-2, and a lifting frame 4-3. The switching mounting base 4-1 is housed within the mounting frame 2. A connecting box 10 is fixedly mounted on the upper side wall of the switching mounting base 4-1, and a connecting seat 11 is fixedly mounted on the top plate of the connecting box 10.

A rotating seat 15 is screwed onto the lifting frame 4-3 via bearings. A centering jaw 16 is fixedly mounted at the lower end of the rotating seat 15, with its centerline overlapping the axis of the rotating seat 15. A drilling tool 7 is clamped within one of the centering jaws 16, and a grinding roller 8 is clamped within the other. A support slide rail 17 is fixedly mounted on the mounting frame 2. The support slide rail 17 is an arc-shaped structure centered on the axis of the connecting seat 11, with open ends. A drive slide rail 18 is movably embedded within the notch of the arc-shaped slide rail. The drive slide rail 18 and the support slide rail 17 are engaged in a circular structure. The drive slide rail 18 and the support slide rail 17 are connected. The support slider 19 is fixedly installed on the lifting frame 4-3. The support slider 19 on the rear lifting frame 4-3 is slidably mounted on the support slide rail 17, and the support slider 19 on the front lifting frame 4-3 is slidably mounted on the drive slide rail 18. The lifting electric screw 22 is fixedly installed on the mounting frame 2, and the movable end of the lifting electric screw 22 is fixedly installed on the drive slide rail 18. Two support rods 20 are fixedly installed on the mounting frame 2 in a symmetrical manner. Support sleeves 21 are fixedly installed at both ends of the drive slide rail 18, and the support sleeves 21 on both sides are movably mounted on the support rods 20 on both sides. The drive mechanism 5 includes a drive motor 5-1, a drive shaft 5-2, a transmission shaft 5-3, and a splined shaft 5-4. The drive shaft 5-2 is screwed onto the connecting seat 11 via bearings, and its lower end extends into the connecting box 10. The drive shaft 5-2 and the connecting seat 11 are coaxial. The drive motor 5-1 is fixedly mounted on the mounting bracket 2, and its output shaft is connected to the upper end of the drive shaft 5-2 via a transmission connection. The transmission shaft 5-3 is screwed onto the inner wall of the connecting box 10 via bearings. One end of the drive shaft 5-2, which extends into the connecting box 10, is connected to the transmission shaft 5-3 via a bevel gear set. Two splined shafts 5-4 are symmetrically mounted on the switching mounting base 4-1 via bearings. The upper ends of the splined shafts 5-4 extend into the connecting box 10.

The lower splined end of the splined shaft 5-4 is movably inserted into the rotating base 15, and the splined shaft 5-4 and the rotating base 15 are coaxial.
[0025] When using this device, the linear motor 3-4 first pushes the feeding bracket 3-2 forward, thereby feeding the centering caliper 6 forward and clamping the workpiece. Then, the linear motor 3-4 moves the feeding bracket 3-2 backward, causing the workpiece clamped by the centering caliper 6 to move to the processing position. The feeding servo motor 9 then rotates the centering caliper 6, causing the workpiece to rotate. This movement and rotation aligns the workpiece's drilling position with the working position of the drilling tool 7. Next, the servo motor 12 is switched on, and the main gear 13 and auxiliary gear 14 drive the... The rotating connecting seat 11 drives the connecting box 10 and the switching mounting seat 4-1 to rotate. The switching mounting seat 4-1 then drives the lifting frame 4-3 to rotate via the switching bracket 4-2, moving the lifting frame 4-3 equipped with the drilling tool 7 above the workpiece. This causes the support slider 19 on the lifting frame 4-3 with the drilling tool 7 to slide within the drive slide rail 18, and the support slider 19 on the other lifting frame 4-3 to slide within the support slide rail 17. The drive motor 5-1 drives the drive shaft 5-2 to rotate, which in turn drives the transmission shaft 5-3 to rotate via a bevel gear set. The transmission shaft 5-3, in turn, drives the splined shaft 5-4 to rotate via the bevel gear set. 4. The drill bit 7 is inserted into the rotating seat 15, which in turn drives the rotating seat 15 to rotate. The rotating seat 15 then drives the drill bit 7 to rotate. The lifting electric screw 22 pushes the drive slide rail 18 downward, which in turn drives the slide rail 18 to cooperate with the support slider 19 inserted therein. This causes the lifting frame 4-3, on which the drill bit 7 is installed, to move downward. The lifting frame 4-3 slides in the lifting groove 4-5 on the switching bracket 4-2 via the lifting slide rail 4-4, so that the drill bit 7 rotates and descends, realizing the drilling of the workpiece. After the workpiece is drilled, the lowered drive slide rail 18 is raised and reset, so that the drive slide rail 18 is connected to the support slide rail 17. Then, the servo motor 1 is switched. 2. Rotate the switching mounting base 4-1 to rotate the lifting frame 4-3 with the grinding roller 8 to the front, so that the support slider 19 on the lifting frame 4-3 with the grinding roller 8 slides into the drive slide rail 18, and the grinding roller 8 is mounted above the workpiece opening. Then, push the grinding roller 8 downward, and drive motor 5-1 drives the grinding roller 8 to rotate through drive shaft 5-2, transmission shaft 5-3, and spline shaft 5-4, so that the grinding roller 8 is inserted into the workpiece opening to achieve grinding processing of the workpiece. After completing the drilling and grinding processing of the workpiece, lift the lifting frame 4-3 to reset, push the feeding bracket 3-2 forward to reset, remove the processed workpiece and load a new workpiece.
[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. This device integrates switchable drilling cutter 7 and grinding roller 8 on the equipment, so that by switching the drilling cutter 7 and grinding roller 8 to the processing position above the workpiece, drilling or grinding processing of the workpiece can be realized, realizing the integrated composite processing of the workpiece by a single equipment. 2. This device is based on a drill bit 7 and a grinding roller 8 that can be switched to a working position. It uses a feeding slide rail 3-1 and a linear motor 3-4 to set up a movable feeding bracket 3-2. A feeding servo motor 9 is set on the feeding bracket 3-2 to set up and rotate the centering caliper 6, thereby positioning the workpiece and cooperating to open and grind the workpiece. 3. This device has two sets of liftable and movable lifting frames 4-3 on the switching bracket 4-2, and the switching bracket 4-2 is set on the mounting frame 2 in conjunction with the switching mounting base 4-1, the connecting box 10, and the connecting base 11. The lifting frame 4-2 is moved and driven by the cooperation of the support slide rail 17 and the drive slide rail 18, and by the support slider 19 on the lifting frame 4-3 being mounted in the support slide rail 17 and the drive slide rail 18 respectively. This enables the drilling cutter 7 or the grinding roller 8 to descend and process the workpiece. 4. This device, in conjunction with the connecting base 11, includes a drive shaft 5-2 and a drive motor 5-1. A transmission shaft 5-3 is housed within the connecting box 10, and splined shafts 5-4, which mate with the two rotating seats 15, are mounted on the switching mounting base 4-1. The transmission shaft 5-3 enables transmission between the drive shaft 5-2 and the two splined shafts 5-4. The drive motor 5-1 then rotates the rotating seats 15, thereby driving the drilling tool 7 and the grinding roller 8 to rotate, while simultaneously ensuring the movement of the lifting frame 4-3. For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features.
