Description

Technical Field

[0001] This application relates to the field of corner code production and processing technology, and in particular to a multi-functional corner code processing head. Background Technology

[0002] Angle brackets are often used to connect adjacent structures in a frame. Common uses include connecting photovoltaic modules and the length and width of window frames.

[0003] Currently, corner brackets are generally divided into two types: insert type and external type. Installation mostly relies on manual assembly. However, many existing insert type corner brackets often fail to balance the two points of easy installation and sturdiness. For example, in order to facilitate installation, some corner brackets are relatively flat and simple, but their connection stability is low after installation, and the frame structure is prone to problems such as skewing and cracking, and even requires reinforcement such as rivets.

[0004] The other part uses various interference fits and other structures for sturdiness, but embedding it into the frame is relatively difficult. Without special tooling, it needs to be installed manually by hammering. When doing repetitive work, it is also relatively easy to make mistakes due to fatigue, which may squeeze the frame or its own complex assembly structure and cause structural deformation.

[0005] For the reasons mentioned above, relevant personnel have proposed a new corner bracket structure, which simplifies the installation process and ensures the stability of the connection by using a small interference fit at the root of the corner bracket and a convex protrusion with a bevel that extends the slope of the guide end on the inner side of the end.

[0006] However, the aforementioned corner brackets are L-shaped, meaning that the small interference structure at the root cannot be directly interconnected. A groove must be dug in the inner corner (the end view is not a complete cylinder) to prevent the two adjacent sections of the frame from interfering with each other when they are joined. Furthermore, the protrusions need to be machined with bevels. Therefore, even without considering the extra metal debris generated by other structural differences, the debris generated by the above two points alone will greatly increase during the processing stage.

[0007] Furthermore, since the processing positions are all inside the corner of the corner code, the debris can easily stop directly at the inside corner of the substrate. The processing of the two is sequential, which means that if the metal debris is not cleaned up in time, it may not only accelerate the damage of the equipment and tools, but also affect the processing accuracy of the grooves and protruding bevels, thus affecting the assembly effect. Therefore, this application proposes a new technical solution. Summary of the Invention

[0008] To ensure the processing accuracy and assembly effect of corner codes, this application provides a multi-functional processing head for corner codes.

There are two tracks in the same set, which are located on both sides of the corresponding tool guide groove one and tool guide groove two, respectively. The side of the clamping bearing facing the track has a roller adapted to the track fixed on the outer ring of the bearing.

[0019] Optionally, the milling cutter shaft is a telescopic rotating structure.

[0020] Optionally, the milling cutter shaft includes a tool connector, a drive shaft, and a sliding rod. The tool connector is located in the cavity enclosed by the cutter plate and the integrated sleeve, and the end facing the cutter plate is recessed to form a polygonal groove. The drive shaft passes through the clamping bearing and is slidably connected to the inner ring of the clamping bearing. At least one end of the drive shaft is a prism adapted to the polygonal groove. The sliding rod penetrates the cutter plate and is slidably connected to the cutter plate.

[0021] The tool joint has an annular groove around the drive shaft, and one end of the sliding rod is slidably connected to the annular groove.

[0022] Optionally, a baffle is provided at the end of the integrated sleeve away from the blade plate, and an elastic sealing strip is provided on the end face of the integrated sleeve that is close to the baffle.

[0023] Optionally, the openings of the tool guide groove one and the tool guide groove two are set as rounded corners or covered with a sound-absorbing layer of fluff.

[0024] Optionally, the suction unit includes a housing, a material bucket, a filter plate, and a motor. The material bucket has a horizontal partition with water-permeable holes. The material bucket is detachably connected to the housing. The filter plate is located in the housing and above the material bucket. The side wall of the housing has an input port. The filter plate has a filter screen located away from the input port. The motor is mounted on the housing and has multiple speed settings.

[0027] The integrated sleeve is fastened to the corner bracket base material, with the inner corner of the integrated sleeve facing the inner corner of the corner bracket. The two ends of the integrated sleeve abut against the two ends of the inner corner of the corner bracket base material. When the milling cutter shaft one and the milling cutter shaft two are working, the suction unit is activated at the same time, so that a negative pressure is formed in the space enclosed by the integrated sleeve, which sucks away the debris generated by the cutting cutter shaft and the cutting tool.

[0028] With the above settings, this application can clean up metal debris in a timely manner while processing corner brackets, slow down the rate of equipment damage, ensure the processing accuracy of the grooves and raised bevels of the corner brackets, and ensure the assembly effect of the corner brackets. Moreover, since the above modifications are concentrated at the head of the machine tool, not only is the new manufacturing cost low, but it is also more suitable for improving the original equipment, and the overall implementation cost is relatively low.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0036] This application discloses a multi-functional processing head for corner codes.

[0037] Reference Figure 1 The corner code multi-functional processing head includes an integrated sleeve 1, a cutter plate 2, a milling cutter shaft 1 3, and a milling cutter shaft 2 4. The integrated sleeve 1 is L-shaped at one end and matches the inner corner of the corner code, that is, it covers the inner corner of the corner code. The integrated sleeve 1 is integrally formed.

[0038] The blade plate 2 is fixed to the integrated sleeve 1 near the processing area, i.e., the end of the corner code strip material that is about to be cut, by bolts, thus covering one end of the cavity of the integrated sleeve 1. The blade plate 2 has a tool guide groove 1 21 and a tool guide groove 22 that match the processing requirements of the groove and the raised bevel at the root of the corner code. The length direction of the tool guide groove 1 21 is parallel to the center line of the inner corner of the corner code, and the groove opening is a long strip; the length direction of the tool guide groove 22 is parallel to the oblique line of the outline of the raised corner code when viewed from the side. Assuming that the angle between the oblique line and the horizontal plane is 45°, the angle between the length direction of the tool guide groove 22 and the horizontal plane is also 45°.

[0039] Milling cutter shaft 1 (3) and milling cutter shaft 2 (4) are movably connected to the cutter plate 2. One end of milling cutter shaft 1 (3) is fitted with a cutting tool and used to mill the root groove of the corner bracket. Milling cutter shaft 1 (3) passes through and moves along the tool guide groove 21. One end of milling cutter shaft 2 (4) is fitted with a cutting tool and used to mill the raised inclined surface of the corner bracket. Milling cutter shaft 2 (4) passes through and moves along the tool guide groove 22.

[0040] That is, the two guide groove structures mentioned above match the tool path of milling grooves and inclined surfaces, so that the cutter plate 2 can not only seal the corner code machining area and reduce the chance of chip ejection, but also not interfere with the cutter axis.

[0041] The inner corner of the integrated sleeve 1 is opposite to the inner corner of the corner bracket, and the two ends respectively abut against the inner corners or the outer ends of the corner bracket base material. The integrated sleeve 1 is provided with a suction port (e.g., an opening at the top of the integrated sleeve 1). After the suction port is fitted with a pipe connector, it is connected to the suction unit 6 through a pipe.

[0042] A set of clamping units 5 is provided on the first milling cutter shaft 3, and another set of clamping units 5 is provided on the second milling cutter shaft 4. The clamping units 5 in the same set include two clamping bearings 51 located on the inner and outer sides of the cutter plate 2. The cutter shaft passes through the inner ring of the clamping bearings 51. Through the setting of the clamping units 5, the first milling cutter shaft 3 and the second milling cutter shaft 4 can be installed on the cutter plate 2, and the cutter plate 2 does not obstruct the sliding and rotation of the first milling cutter shaft 3 and the second milling cutter shaft 4.

[0043] When in use, the integrated sleeve 1 is fastened to the corner code base material, such as a stroke base material with an L-shaped end view. The inner corner of the integrated sleeve 1 is opposite to the inner corner of the corner code, and the two ends of the integrated sleeve 1 are respectively in contact with the two ends of the inner corner of the corner code base material. When the milling cutter shaft 3 and the milling cutter shaft 4 are working, the suction unit 6 is activated at the same time, so that a negative pressure is formed in the space enclosed by the integrated sleeve 1, which sucks away the debris generated by the cutting shaft and the cutting tool.

[0044] With the above settings, this application can clean up metal debris in a timely manner while processing corner brackets, slow down the rate of equipment damage, ensure the processing accuracy of the grooves and raised bevels of the corner brackets, and ensure the assembly effect of the corner brackets. Moreover, since the above modifications are concentrated at the head of the machine tool, not only is the new manufacturing cost low, but it is also more suitable for improving the original equipment, and the overall implementation cost is relatively low.

[0045] In another embodiment of this application, the blade plate 2 is provided with a set of rails 52 on the side of each clamping bearing 51 facing the blade plate 2. There are two rails 52 in the same set and they are located on both sides of the corresponding tool guide groove 1 21 and tool guide groove 22 respectively. The length of the rail 52 matches the length of the tool guide groove 1 21 and tool guide groove 22. The rail 52 is used to guide the movement path of the clamping bearing 51.

[0046] A roller 53 adapted to the track 52 is mounted on the side of the clamping bearing 51 facing the track 52. The roller 53 is mounted on the outer ring of the bearing, and two rollers 53 are mounted on the outer ring of each clamping bearing 51. The roller 53 can be an I-beam roller. Example:

[0047] The track 52 has a slot along its length with openings on both sides, and the slot faces the clamping bearing 51. The roller 53 includes a roller column that passes through one side of the slot in the track 52, and the other end of the roller column extends from the other side of the slot in the track 52. Fixed edges at both ends of the roller column extend beyond the outer edge of the slot in the track 52, forming limiting blocks. The clamping bearing 51, facing the track 52, has a connecting rod fixed to its outer bearing ring. The connecting rod extends from the slot in the track 52 facing the clamping shaft and is rotatably connected to the roller column. Two rollers 53 are installed in each track 52. This arrangement effectively prevents the rollers 53 from slipping, reduces vibrations that may occur during slippage, and reduces resistance when the clamping bearing 51 moves along the tool guide slot, making it less prone to damage and resulting in smoother operation.

[0048] The reason for the above setting is that if the clamping bearing 51 is directly moved along the tool guide groove 1 21 and the tool guide groove 22, the clamping bearing 51 will rub against the tool plate 2 during the movement, causing wear and reducing the clamping force of the clamping bearing 51 on the milling cutter shaft 1 3 and the milling cutter shaft 2 4.

[0049] As described above, when the clamping bearing 51 moves along the tool guide groove 1 21 and the tool guide groove 22, the roller 53 rolls in the track 52 instead of the clamping bearing 51 directly rubbing against the surface of the blade plate 2, which reduces the wear on the clamping bearing 51 and the blade plate 2 and extends their service life.

[0050] Because the groove at the root of the corner bracket is relatively long while the cutting tool is relatively short, and considering the risk of breakage under stress, it is generally difficult to mill the groove completely in one go unless a custom-made or higher-quality tool is purchased. This results in the corner bracket being cut from the profile with a section of the groove at the root being shorter than expected, requiring an additional process. Therefore, the following settings are made:

[0051] In another embodiment of this application, the milling cutter shaft 3 is a telescopic rotating structure. With this setting, even if the length of the milling cutter shaft 3 is limited, the root groove of a single corner code can be milled by adjusting the length of the extension of the milling cutter shaft 3. For example, the milling length at one time is the width of the corner code + 1cm, thereby ensuring the integrity of the root groove of the corner code and avoiding the situation where the groove is a section too short.

[0052] In another embodiment of this application, the milling cutter shaft 3 includes a tool connector 31, a drive shaft 32, and a sliding rod 33. The tool connector 31 is located in the cavity enclosed by the cutter plate 2 and the integrated sleeve 1, and one end facing the cutter plate 2 has a tool guide groove that is recessed to form a polygonal groove, such as a hexagon. The drive shaft 32 passes through the clamping bearing 51 and is slidably connected to the inner ring of the clamping bearing 51. At least one end of the drive shaft 32 is a prism adapted to the polygonal groove, such as a hexagonal prism. One end of the drive shaft 32 is inserted into the groove to connect the two. When the drive shaft 32 rotates, it can drive the tool connector 31 to rotate together. The other end of the drive shaft 32 is connected to a drive motor 64 or a machine head used by the machine tool to drive the tool to rotate.

[0053] The tool joint 31 has an annular groove 34 around the drive shaft 32. One end of the sliding rod 33 extends into the annular groove 34 and is slidably connected along the circumferential direction of the annular groove 34. The sliding rod 33 can slide in the annular groove 34 but cannot extend or retract in the groove. For example, the annular groove 34 is a T-shaped groove, and the end of the sliding rod 33 near the annular groove 34 is I-shaped.

[0054] The end of the sliding rod 33 away from the tool connector 31 penetrates the tool plate 2 and is slidably connected to the tool plate 2. Connection example: the sliding rod 33 passes through the pre-set guide groove on the tool plate 2, and the guide groove is coated with lubricant to ensure that the sliding rod 33 can slide smoothly.

[0055] The sliding rod 33 is located outside the track 52 and the clamping bearing 51, or at least one end away from the tool joint 31 is located outside the track 52 and the clamping bearing 51, because this end is used to connect the mechanism that pushes it to extend and retract; each tool joint 31 is connected to at least two sliding rods 33, and the two sliding rods 33 are located on both sides of the tool guide groove, symmetrically arranged; pushing example: the machine head is equipped with an electric cylinder, the extension rod end of the electric cylinder is fixed to the seat plate surrounding the tool shaft, the seat plate and the sliding rod 33 are fixed, when the electric cylinder drives the seat plate to extend and retract, it synchronously drives the sliding rod 33 to extend and retract.

[0056] With the above configuration, when milling the groove at the root of the corner bracket, the drive shaft 32 rotates and drives the tool connector 31 to rotate, while the sliding rod 33 slides in the annular groove 34, without interfering with the rotation of the tool connector 31. When machining along the groove axis is required, the motor 64 driving the tool shaft, the machine head, etc., can remain stationary; only the sliding rod 33 needs to push the tool connector 31 to extend or retract. Simultaneously, because the sliding rod 33 is in the groove, it provides a certain limiting effect on the tool connector 31, preventing it from wobbling during high-speed rotation. The clamping bearing 51 supports the drive shaft 32, ensuring smooth transmission.

[0057] In another embodiment of this application, a baffle is detachably connected to the end of the integrated sleeve 1 away from the blade plate 2 by bolts. The shape of the baffle fits the end contour of the integrated sleeve 1, which can close the end of the integrated sleeve 1. An elastic sealing strip is fixed to the end face of the integrated sleeve 1 near the baffle. The fixing method can be adhesive or snap-fit ​​to the end face of the integrated sleeve 1. When the integrated sleeve 1 is fastened to the corner bracket base material, the sealing strip is in close contact with the surface of the corner bracket base material to form an elastic seal.

[0058] With the above configuration, the baffle, integrated sleeve 1, blade 2, and corner bracket base material together enclose a relatively closed processing space. During the operation of the suction unit 6, due to the relatively closed space, only a small suction force is needed to create negative pressure within the space, sucking up heavier metal debris, thus improving suction efficiency while reducing energy consumption. The sealing strip ensures that there are as few gaps as possible between the corner bracket base materials, avoiding whistling noise during high-speed suction and reducing the problem of vibration being directly transmitted to the integrated sleeve 1, causing it to vibrate. Therefore, it is preferable to install an elastic layer on the integrated sleeve 1 at each contact point with the corner bracket.

[0059] In another embodiment of this application, the edges of the tool guide groove 1 21 and the tool guide groove 22 are treated as rounded corners or covered with a sound-absorbing layer of fluff.

[0060] Before installing the sound-absorbing layer, rounded corners can be made to allow the sound-absorbing layer to better cover the rounded corner area. The sound-absorbing layer can be made of fabric or synthetic leather with a fleece lining, and fixed to the tool guide groove 1 21 and tool guide groove 2 22 by adhesive bonding. During suction, the rounded corners and the sound-absorbing layer reduce the whistling generated by high-speed suction.

[0061] In another embodiment of this application, the suction unit 6 includes a housing 61, a material cylinder 62, a filter plate 63 and a motor 64. The material cylinder 62 is cylindrical in shape and is detachably connected to the inside of the housing 61.

[0062] Example: The barrel 62 is inverted T-shaped in front view. The outer shell 61 is fitted over the barrel 62 from top to bottom and the bottom of the barrel 62 rests on the upper part of the bottom side structure. The two are preferably sealed with a sealing strip.

[0063] The barrel 62 is fixed with a transverse partition, such as a stepped block on the inner wall of the barrel, which is fixed by bolts and the stepped block.

[0064] Because the cutting area of ​​the base material is at a high temperature when cutting metal, coolant is often sprayed to cool it down at the same time. At this time, the suction unit 6 is used to suction, and the coolant is also sucked into the barrel 62. Therefore, a baffle is provided, and multiple water-permeable holes are opened along the thickness of the baffle. The baffle divides the inside of the barrel 62 into an upper chip collection area and a lower liquid collection area. This setting allows the coolant to flow naturally into the lower liquid collection area. A pipe is fixed at the bottom of the barrel 62 and there is a drain valve on the pipe for periodically draining the coolant.

[0065] The filter plate 63 is detachably fixed inside the housing 61 by bolts and is located above the material cylinder 62. The filter plate 63 can be a hollow plate to reduce weight. The side wall of the housing 61 has an input port and is connected to the integrated sleeve 1 through a pipe.

[0066] A filter screen is fixed to the filter plate 63 at a position away from the input port of the housing 61. The filter screen is used to filter out fine metal shavings and prevent them from being sucked into the suction unit 6, which could cause malfunctions.

[0067] According to the above settings, after the metal scraps enter the feed cylinder 62, they cannot go directly upwards. They must first move horizontally and suspended in the air. Moreover, they enter a larger space through a small pipe and are affected by both the sudden changes in fluid dynamics and gravity, which makes them more likely to fall down and stop inside. This also makes it less likely for the subsequent filter screen to be clogged.

[0068] The motor 64 can be installed on either the inner or outer top of the housing 61, and the compatible controller with electrical connection has multiple speed settings.

[0069] The controller is used to electrically connect to the control system of the corner code processing device, and the controller is configured to: obtain the head control command corresponding to the tool; if the command indicates that the tool stops rotating, adjust the speed of the fan to the preset low speed.

[0070] The control system automatically adjusts the gear. When corner code cutting is required, it switches to the preset high-speed gear, and when corner code cutting is not required, it switches to the preset low-speed gear.

[0071] The reason for the above settings is that when the coolant needs to be drained, if the housing 61 of the suction unit 6 is under a large negative pressure, it will be difficult to drain the coolant. If the machine is turned off directly, the repeated switching on and off will consume more electricity and may even cause the machine to malfunction. Therefore, the power is reduced and the fan speed is adjusted to a low speed. On the one hand, the coolant can be drained smoothly, and on the other hand, energy consumption can be saved and the service life of the machine can be extended.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
