Description

Technical Field

[0001] The present invention relates to the technical field of profile processing and manufacturing, and particularly to a profile processing center and a working method thereof. Background Technique

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] According to different uses, profiles have various processing methods. Taking the aluminum alloy profiles commonly used in doors and windows (hereinafter referred to as profiles) as an example, when drilling and milling the profiles, the two ends of the profiles are generally fixed by clamps, and then the processing equipment (such as a drill bit or a milling cutter) feeds vertically downward from the upper surface of the profile to achieve processing.

[0004] The stiffness of the profile itself is limited. When the length is too long, it will bend to a certain extent, and its bending deformation is usually proportional to the square of the profile length. At the same time, the profile will also be affected by the impact force when the drill bit or milling cutter feeds vertically downward, and the impact force in the horizontal direction of the processing surface when the drill bit or milling cutter rotates. As a result, when the profile is processed in a bent state, the force application direction of the drill bit or milling cutter is not perpendicular to the local surface of the profile, resulting in the axis of the processed hole or groove being inclined (especially for small-diameter deep holes). During subsequent assembly, when bolts or pins are inserted into the inclined holes or grooves, lateral stress is generated, reducing the connection strength between the profiles. For hinge holes, guide holes that require high perpendicularity, or sliding grooves with high flatness, it may cause jamming of moving parts. Summary of the Invention

[0005] In order to solve the technical problems in the above background technique, the present invention provides a profile processing center and a working method thereof. Two groups of fixed clamps are used to clamp the two ends of the profile, and a follow-up clamp is used to clamp the middle processing area. During processing, the follow-up clamp remains in a clamped state and follows the movement of the processing mechanism to ensure that the processing area is always within the clamping influence range of the follow-up clamp, ensuring that the profile is not easily bent during processing and solving the problem of unsatisfactory processing accuracy caused by profile bending.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The first aspect of the present invention provides a profile processing center, including:

[0008] A processing mechanism that runs linearly to each processing position and realizes drilling or milling processing of the profile through a feeding movement in the vertical direction;

[0009] The fixture includes a fixed fixture and a follower fixture arranged on a guide rail. The fixed fixture clamps both ends of the profile, and the follower fixture clamps the processing area in the middle of the profile and moves following the processing mechanism in the clamped state.

[0010] Among them, the follower fixture includes a first frame slidably connected to the guide rail. A material supporting roller is provided on the upper surface of the first frame. Above the space of the material supporting roller, a pressing wheel A and a pressing wheel B are vertically arranged. A horizontal air cylinder is arranged inside the first frame, and the horizontal air cylinder drives one of the pressing wheels to move to clamp the front and rear sides of the profile.

[0011] Furthermore, the lower bottom surface of the first frame is connected to a first driving motor through a first connecting piece. The output shaft of the first driving motor is connected to a first driving gear, and the first driving gear meshes with a rack.

[0012] Furthermore, a vertical air cylinder is provided at one end of the first frame. The action end of the vertical air cylinder is connected to a pressing wheel C through a vertical connecting rod. The pressing wheel C is located above the space at the end of the material supporting roller. The vertical air cylinder drives the pressing wheel C to move in the vertical direction to press the profile onto the material supporting roller from the vertical direction.

[0013] Furthermore, all the pressing wheels can rotate.

[0014] Furthermore, corresponding air blowing blocks are provided for all the pressing wheels, and nozzles are provided on the air blowing blocks.

[0015] Furthermore, the fixed fixture includes a second frame slidably connected to the guide rail. A jaw A and a jaw B are provided on the second frame. A clamping action element is arranged inside the second frame, and the clamping action element drives one of the jaws to move to achieve clamping.

[0016] Furthermore, the second frame is connected to a second driving motor through a second connecting piece. The output shaft of the second driving motor is connected to a second driving gear, and the second driving gear meshes with a rack.

[0017] Furthermore, a positioning plate is provided at one end of the guide rail. The positioning plate moves along the direction of the guide rail, and positioning is achieved by the positioning plate contacting the profile to be processed.

[0018] Furthermore, the processing mechanism is located in the upper space of the guide rail, and a rack is provided in the lower space of the guide rail. The rack is arranged side by side with the guide rail.

[0019] The second aspect of the present invention provides a working method of the above profile processing center, including the following steps:

[0020] The profile to be processed is placed in the fixed fixture and the follower fixture. The two fixed fixtures act to clamp both ends of the profile, and the positioning plate moves to the position where it abuts against one end of the profile according to the length of the profile to form a reference position.

[0021] The processing mechanism moves linearly to the processing position. The follower fixture moves along the guide rail direction and follows the processing mechanism to move into the area where the processing position is located. The follower fixture acts to clamp the processing area of the profile, and the processing mechanism acts to perform the current processing.

[0022] After the current processing is completed, the processing mechanism moves linearly to the next processing position. The follower fixture remains in the clamped state and follows the processing mechanism to move into the area where the next processing position is located. The processing mechanism acts to perform the processing.

[0023] After all the processing is completed, the processing mechanism, the follower fixture, and the positioning plate are reset. The fixed fixture acts to release the profile, and the profile is transferred to the next process.

[0024] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0025] 1. The two ends of the profile are clamped by the fixed fixture, and the processing area in the middle is clamped by the follower fixture. During the processing, the follower fixture remains in the clamped state and follows the processing mechanism to move to each processing position, ensuring that the processing area of the profile is always within the clamping influence range of the follower fixture, ensuring that the processing area of the profile is fixed during the processing, so that it is not easy to bend, and solving the problem of unsatisfactory processing accuracy caused by the bending of the profile.

[0026] 2. During the linear movement of the follower fixture along the guide rail following the processing mechanism, the clamping state of the profile is not changed, reducing the time for re-arranging each fixture, and at the same time avoiding the error caused by the repeated tightening and loosening of the fixtures when each fixture is arranged.

[0027] 3. Considering that the cross-section of the profile may not be a regular rectangle, there may be inclined surfaces or structures such as "ribs" and "edges". The follower fixture may not be able to reliably clamp the profile only by the pressing wheels A and B arranged relatively on the front and rear sides of the profile. The introduced pressing wheel C further presses the profile onto the supporting roller from the vertical direction. And since the upper and lower surfaces of the profile are the processing surfaces, considering that the vertical pressing cannot cause movement interference with the feeding action of the processing mechanism, the pressing wheel C is arranged in the upper space at the end of the supporting roller and presses from above the edge of the profile.

[0039] The present invention will be further described below in conjunction with the drawings and embodiments.

[0040] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0041] In the following embodiments, the length direction of the profile is the x-axis or x-direction, the width direction is the y-axis or y-direction, and the height direction is the z-axis or z-direction, and the three directions are perpendicular to each other.

[0042] Embodiment 1:

[0043] This embodiment takes the realization of drilling as an example to explain the specific solution. It can be understood that this solution can also be the milling of profiles, or the feeding of the tool downward in the vertical direction, or any processing method that can cause the profile to bend.

[0044] As Figures 1 - 2 shown, a profile processing center includes a fixed fixture and a follower fixture 4 arranged on a guide rail 1. A processing mechanism 6 is provided in the space above the guide rail 1. A positioning plate 2 is provided at one end of the guide rail 1. The space where the processing mechanism 6, together with the guide rail 1, the fixtures and related components, is enclosed by an enclosure mechanism 7 for protection.

[0045] There are at least two groups of fixed fixtures, including a first fixed fixture 3 and a second fixed fixture 5. Both ends of the profile (also called the workpiece) to be processed are clamped by the first fixed fixture 3 and the second fixed fixture 5 respectively, and the processing area in the middle is clamped by the follower fixture 4. According to the position requirements of the drilling process, the processing mechanism 6 runs linearly along the direction parallel to the guide rail 1. After reaching the set position, the drill bit of the processing mechanism 6 adjusts its horizontal position and performs drilling downward vertically from above the profile.

[0046] During drilling, the follower fixture 4 follows the movement of the processing mechanism 6 and moves linearly synchronously on the guide rail 1. It is in a clamped state during the movement to ensure that the drilling area of the profile is always in a state of being clamped by the follower fixture 4. The stiffness problem of the profile is improved by using the follower fixture 4, and the follower fixture 4 helps the profile bear the vertically downward impact force during drilling, alleviating the bending of the profile itself and solving the problem of unsatisfactory drilling accuracy caused by the bending of the profile.

[0047] As a further implementation method, the processing mechanism 6 at least includes a drill bit and a processing mechanism main body that drives the drill bit to run. The processing mechanism main body drives the drill bit to rotate and feed along the vertical direction (z-axis) to achieve drilling. The processing mechanism main body can drive the drill bit to run along the direction parallel to the guide rail 1 (x-axis), and can also drive the drill bit to run along the width direction (y-axis) of the profile to change the position of the drill hole in the horizontal direction of the profile.

[0048] As a further implementation method, the structure type of the processing mechanism 6 is not limited, and an existing mature product can be used.

[0049] As Figure 3 shown, a positioning plate 2 is provided at one end of the guide rail 1. The profile to be processed is placed at a position close to the positioning plate 2. The positioning plate 2 moves towards the profile along the direction where the guide rail 1 is located. When the end face of the positioning plate 2 abuts against the end of the profile, the position where the positioning plate 2 is located is the reference position during the linear movement of the processing mechanism 6.

[0050] As a further embodiment, the positioning plate 2 is driven by a corresponding driving component to move along the direction where the guide rail 1 is located. When the placement position of the profile changes, for example, there are errors during the feeding by the robot, etc., the initial position where the positioning plate 2 is located may not be able to achieve abutting against one end of the profile. At this time, it is necessary for the driving component to drive the positioning plate 2 to move to the position where it abuts against one end of the profile, and the reference position where the end face of the profile is located is determined according to the movement stroke between the initial position and the abutting position of the positioning plate 2.

[0051] The structures of the first fixing fixture 3 and the second fixing fixture 5 are the same. In this embodiment, the first fixing fixture 3 is taken as an example to show the specific structure.

[0052] As shown in Figure 4 As shown, the first fixing fixture 3 includes a second frame 34 slidably connected to the guide rail 1. The upper surface of the second frame 34 is provided with a jaw A36 and a jaw B37. A clamping action element 35 is arranged inside the second frame 34, and the clamping action element 35 drives one of the jaws to move to achieve clamping.

[0053] In this embodiment, the jaw A36 is a movable jaw driven by the clamping action element 35. The jaw A36 is slidably connected through a slide rail arranged on the upper surface of the second frame 34. The jaw B37 is a fixed jaw fixedly connected to the upper surface of the second frame 34.

[0054] In this embodiment, the specific structure type of the clamping action element 35 is not limited. For example, it can be an electric cylinder or a pneumatic cylinder. The clamping action element 35 drives the jaw A36 to move along the direction close to or away from the jaw B37 to achieve clamping of the profile.

[0055] As a further embodiment, the second frame 34 is connected to the second driving motor 31 through a second connecting member 33. The output shaft of the second driving motor 31 is connected to a second driving gear 32. The second driving gear 32 meshes with a rack, and the rack is connected to the guide rail 1 and arranged side by side with the guide rail 1.

[0056] In this embodiment, the plane formed by the upper surfaces of the second frames 34 of the two groups of fixing fixtures is used to carry the profile. Since the lengths of the profiles are different, each time drilling processing is performed, the profiles placed in the machining center may not be directly placed on the upper surface of the second frame 34. Therefore, it is necessary for the second driving motor 31 to drive the second driving gear 32 to make the fixing fixture move along the track 1 so as to change the distance between the two groups of fixing fixtures, or change the distance between the two groups of fixing fixtures and the positioning plate 2, so as to cope with the fixed clamping of profiles with different lengths. After the distance adjustment is completed, both ends of the profile are clamped by the fixing fixtures, and the drilling processing starts. During the processing, the position of the fixing fixture relative to the guide rail 1 no longer changes.

[0057] As shown in Figure 5As shown in the figure, the follower fixture 4 includes a first frame 44 slidably connected to the guide rail 1. A material supporting roller 48 is provided on the upper surface of the first frame 44. Above the space of the material supporting roller 48, a vertically arranged pressing wheel A 46 and a pressing wheel B 47 are provided. Inside the first frame 44, a horizontal cylinder 45 is provided, and the horizontal cylinder 45 drives one of the pressing wheels to clamp the front and rear sides of the profile.

[0058] As Figure 5 shown in the figure, the lower bottom surface of the first frame 44 is connected to a first driving motor 41 through a first connecting member 43. The output shaft of the first driving motor 41 is connected to a first driving gear 42. The first driving gear 42 meshes with a rack, and the rack is connected to the guide rail 1 and arranged side by side with the guide rail 1.

[0059] In this embodiment, there are at least two groups of material supporting rollers 48, and each group of material supporting rollers 48 can rotate, and the formed rolling plane serves as the plane for supporting the profile.

[0060] During the drilling process, the processing mechanism 6 moves linearly in the space above the guide rail 1 along the direction where the guide rail 1 is located. The first driving motor 41 drives the first driving gear 42 to make the follower fixture 4 move along the track 1 and synchronously with the processing mechanism 6. When the processing mechanism 6 reaches the drilling position, the follower fixture 4 stays within the range near the drilling position, ensuring that the drilling area is always within the clamping influence area of the follower fixture 4, so as to ensure that during the processing, the drilling area of the profile is fixed and thus not prone to bending, and solve the problem of unsatisfactory drilling accuracy caused by the bending of the profile.

[0061] Specifically, after the profile abuts against the positioning plate 2, taking the position of the positioning plate 2 as the 0 position, the distance between the current drilling position to be processed and the 0 position in the x-axis direction is set as A1. The processing mechanism 6 runs along the x-axis direction to the position A1 to reach the current drilling position; while the processing mechanism 6 is moving, the follower fixture 4 moves synchronously with the processing mechanism 6 to the position A1. After the hole at the position A1 is processed, the processing mechanism 6 moves to the next drilling position A2, and the follower fixture 4 remains in the clamped state and moves synchronously with the processing mechanism 6 to the position A2. And so on, until all the holes at the drilling positions are processed, the follower fixture 4 and the processing mechanism 6 are reset, the two groups of fixed fixtures are loosened, and the profile is removed from the machining center.

[0062] As Figure 6As shown, one end of the first frame 44 is provided with a vertical cylinder 49. The moving end of the vertical cylinder 49 is connected to a pressing wheel C492 through a vertical connecting rod 491. The pressing wheel C492 is located in the upper space at the end of the material supporting roller 48. By driving the pressing wheel C492 to rise or fall in the vertical direction by the vertical cylinder 49, when the pressing wheel C492 descends, the profile can be pressed onto the material supporting roller 48 from the vertical direction. Since the cross-section of the profile may not be a regular rectangle, there may be inclined surfaces, "ribs" or "edges" structures. The follower fixture 4 may not be able to reliably clamp the profile only relying on the pressing wheels A46 and B47 relatively arranged on the front and rear sides of the profile. Therefore, the pressing wheel C492 is introduced to further press the profile onto the material supporting roller 48 from the vertical direction. And since the upper and lower surfaces of the profile are machined surfaces, considering that there should be no movement interference with the drill bit of the machining mechanism 6 during vertical pressing, the pressing wheel C492 is arranged in the upper space at the end of the material supporting roller 48 to press from above the edge of the profile.

[0063] The pressing wheels A46, B47 and C492 can all rotate, ensuring that after the profile is pressed, during the linear movement of the follower fixture 4 along the guide rail 1 following the machining mechanism 6, the three groups of pressing wheels can rotate, thus ensuring that the clamping state of the profile remains unchanged, reducing the time for re-arranging each fixture, and at the same time avoiding the errors caused by the repeated tightening and loosening of the fixtures when arranging the fixtures.

[0064] Fixture arrangement means that when the profile is loaded into the fixture, the fixture needs to be moved to both ends of the profile according to the length of the profile to fix the profile. When the length of the profile exceeds a certain value, its bending amount will affect the drilling accuracy. The traditional method is to add a third fixture in the middle of the profile, clamp the position to be drilled with the third fixture and then perform drilling processing. After the processing is completed, loosen the third fixture and then adjust the position of the third fixture according to the next drilling position. And this method requires the fixture to act repeatedly during one processing, causing additional wear to the fixture itself and thus generating errors, having a certain impact on the processing accuracy and also increasing the processing cost. In this solution, after the three groups of fixtures clamp the profile, they maintain their respective clamping states. The follower fixture uses pressing wheels as the "claw" in contact with the profile, and can move to the processing area following the machining mechanism 6 in the clamped state. After the profile is processed, all the fixtures are loosened, thus reducing the time for re-arranging each fixture, avoiding the errors caused by the repeated tightening and loosening of the fixtures when arranging the fixtures, and at the same time reducing the processing time required.

[0065] Both the pressing wheel A46 and the pressing wheel B47 include a pressing wheel body and a wheel seat. A blowing block A461 is provided on the wheel seat of the pressing wheel A46, and a blowing block B471 is provided on the wheel seat of the pressing wheel B47. A blowing block C493 is provided on the vertical connecting rod 491. Nozzles are provided on the blowing blocks corresponding to the three groups of pressing wheels, and compressed gas is ejected from the nozzles for cleaning the surface of the profile and the aluminum chips generated during processing.

[0066] In the machining center with the above structure, two sets of fixed fixtures are used to clamp both ends of the profile, and a follow-up fixture is used to clamp the middle processing area. During the drilling process, the follow-up fixture remains clamped and moves with the processing mechanism 6 to each processing position, ensuring that the drilling area is always within the clamping influence range of the follow-up fixture, ensuring that the drilling area of the profile is fixed during processing, so that it is not easy to bend, and solving the problem of unsatisfactory drilling accuracy caused by the bending of the profile.

[0067] The above embodiments take drilling as an example to show the relevant structure of the follow-up fixture in the machining center. It can be understood that the present solution is not limited to drilling, but can also be milling, or a processing method that can feed the tool vertically downward. Therefore, the processing mechanism 6 can also be a processing device with a milling cutter.

[0068] In addition, it should be noted that the z-axis direction of the processing mechanism 6 is the feeding direction of the tool, and the tool can move in the x-axis direction and the y-axis direction for adjusting the processing position. When moving along the x-axis direction, the follow-up fixture 4 performs a follow-up action.

[0069] Embodiment 2:

[0070] The working method of the above profile machining center includes the following steps:

[0071] The profile to be processed is placed in the fixed fixture and the follow-up fixture. The two fixed fixtures act to clamp both ends of the profile, and the positioning plate moves to the position abutting against one end of the profile according to the length of the profile to form a reference position;

[0072] The processing mechanism moves linearly to the processing position, and the follow-up fixture moves along the guide rail direction to the area where the processing position is located following the processing mechanism. The follow-up fixture acts to clamp the processing area of the profile, and the processing mechanism acts to perform the current processing;

[0073] After the current processing is completed, the processing mechanism moves linearly to the next processing position. The follow-up fixture remains clamped and moves with the processing mechanism to the area where the next processing position is located. The processing mechanism acts to perform the processing;

[0074] After all the processing is completed, the processing mechanism, the follow-up fixture and the positioning plate are reset. The fixed fixture acts to release the profile, and the profile is transferred to the next process.

[0075] Clamp both ends of the profile using two groups of fixed jigs, and use a follower jig to clamp the machining area in the middle. During the drilling process, the follower jig remains clamped and moves with the machining mechanism to each machining position, ensuring that the drilling area is always within the clamping influence range of the follower jig, guaranteeing that the drilling area of the profile is fixed during machining, so that it is not prone to bending, and solving the problem of unsatisfactory drilling accuracy caused by profile bending.

[0076] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
