Abstract
Description
Technical Field
[0001] This utility model relates to the field of profile clamps, and in particular to a general-purpose profile clamp. Background Technology
[0002] There are many types of doors and windows, including casement doors and windows, sliding doors and windows, folding doors and windows, top-hung windows, and bottom-hung windows. This results in a complex and diverse range of door and window profiles. Common classifications include frames, mullions, and inward-opening sashes. Frames are generally rectangular in cross-section, and the size varies depending on the application. Mullions are generally reinforced mullions, which include an upper section (outer reinforced part) with a rectangular cross-section, a middle crossbeam, and a lower section with a rectangular cross-section. Inward-opening sashes have a Z-shaped cross-section, including a column. The upper and lower ends of the column are equipped with upper and lower crossbeams, which are located on both sides of the column.
[0003] The existing profile clamp includes an upper pressure plate driven by a cylinder, a fixed positioning plate and a front positioning plate arranged opposite each other. The fixed positioning plate is higher than the front positioning plate. The front positioning plate is equipped with a cylinder that can move closer to and further away from the fixed positioning plate. When clamping a regular frame profile (with a rectangular cross-section), the upper pressure plate presses against the top of the profile, and the front positioning plate presses against the lower side of the profile to cooperate with the fixed positioning plate to clamp the profile.
[0004] When the above fixtures are used to clamp the reinforcing mullion, the side of the crossbeam abuts against the fixed positioning plate. As the front positioning plate moves closer to the side of the lower section of the reinforcing mullion, the fixed positioning plate cannot contact the lower section of the reinforcing mullion due to the constraint of the crossbeam. Furthermore, the cylinder of the front positioning plate cannot stop at a certain position in the middle. This causes the front positioning plate to move closer to the fixed positioning plate, resulting in the reinforcing mullion becoming skewed. This prevents the existing machine tool from properly sawing the reinforcing mullion. Because the inner fan has an arc surface and the contact surface with the machine tool table is not flat when the manufacturing precision of the raw material is low, and the upper crossbeam of the inner fan is offset to one side, when the above fixtures are used to clamp the inner fan, the upper pressure plate will press the inner fan skewed, failing to meet the clamping requirements and making processing impossible. In other words, the existing profile fixtures have low versatility. When processing reinforcing mullions and inner fans on the machine tool, it is necessary to replace them with the corresponding profile fixtures to meet the clamping requirements and ensure normal processing. However, replacing the fixtures results in low processing efficiency and increases the number of machine tool parts, thus increasing management costs. Utility Model Content
[0005] To address the technical problems of existing profile clamps, this invention provides a universal profile clamp that can meet the clamping requirements of various profiles, eliminates the need to replace clamps, improves processing efficiency, and has a lower manufacturing cost.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a general-purpose profile clamp, including a fixed positioning plate, and further comprising:
[0007] A first movable plate is connected to a drive motor and can be movably mounted on the machine tool.
[0008] A lower movable positioning plate is disposed at the end of the first movable plate near the fixed positioning plate;
[0009] A second movable plate is movably disposed above the first movable plate. The moving direction of the second movable plate is the same as that of the first movable plate. A tail plate is provided at the rear of the second movable plate along the moving direction of the second movable plate, and a second drive cylinder is connected to the rear of the tail plate.
[0010] A limiting component is disposed on the first movable plate and located at the front of the tail plate, and the limiting component is capable of abutting against the tail plate;
[0011] An upper movable positioning plate is connected to a first driving cylinder, which is disposed on a second movable plate. The moving direction of the upper movable positioning plate on the movable seat is the same as the moving direction of the first movable plate.
[0012] This utility model features a lower moving positioning plate and an upper moving positioning plate, each connected to a drive component. The drive component of the upper moving positioning plate is also connected to another drive component, enabling it to move relative to the lower positioning plate. The extension control of the lower and upper moving positioning plates can be achieved through the coordinated operation of the various drive components, thereby meeting the clamping requirements of the frame, the reinforcing mullion, and the inward-opening fan profile. It has a high level of versatility and mostly uses cylinders for driving, resulting in lower manufacturing costs compared to using motors.
[0013] Furthermore, the drive motor is mounted on a mounting plate, which can be connected to the machine tool. The output shaft of the drive motor is connected to a lead screw via a belt drive assembly. The lead screw is rotatably mounted on the mounting plate. A nut seat is provided on the lead screw, and a protective sleeve is coaxially connected to the nut seat. The protective sleeve is fitted onto the lead screw and is connected to the rear of the first moving plate.
[0014] This invention, by setting a protective sleeve, not only transmits power to drive the first moving plate to move, but also protects the lead screw and nut seat from the influence of dust and chips.
[0015] Furthermore, the output shaft of the drive motor is connected to a speed reducer, which is mounted on the mounting plate, and the output shaft of the speed reducer is connected to the belt drive assembly.
[0016] Furthermore, a hinge seat is provided on one side of the mounting plate for connecting to the machine tool, and a push-pull plate is provided at the end of the protective sleeve, which is connected to the first moving plate via a pin.
[0017] This invention uses a hinge and a pin to transmit the power of the drive motor to the first moving plate through a linkage mechanism. Compared with the linear push method, it saves space in the moving direction and facilitates the spatial layout of the machine tool.
[0018] Furthermore, the limiting component includes a limiting support and an adjusting bolt. The limiting support is disposed on the first movable plate, and the adjusting bolt is horizontally disposed on the limiting support. The head of the adjusting bolt can abut against the tail plate.
[0019] This invention improves the flexibility of the fixture by setting an adjusting screw to adjust the limiting position of the limiting component according to the size of the profile.
[0020] Furthermore, when the first drive cylinder and the second drive cylinder retract, the upper moving positioning plate is located behind the lower moving positioning plate.
[0021] Furthermore, it also includes an upper clamping plate, which is connected to an upper clamping cylinder, and the upper clamping plate can press tightly against the upper surface of the profile.
[0022] As can be seen from the above technical solutions, this utility model has the following advantages:
[0023] This utility model provides a universal profile clamp. It features a lower and upper movable positioning plate, each connected to a drive component. The drive component of the upper movable positioning plate is also connected to another drive component, allowing it to move relative to the lower positioning plate. The coordinated operation of these drive components controls the extension of the lower and upper movable positioning plates, thus meeting the clamping requirements for frame profiles, reinforcing mullions, and inward-opening fan profiles. It boasts a high degree of versatility and primarily uses cylinders for drive, resulting in lower manufacturing costs compared to motors. A protective sleeve is included to transmit power to the first movable plate while protecting the lead screw and nut seat from dust and chips. A hinge and pin mechanism transmit the power of the drive motor to the first movable plate, saving space in the moving direction compared to linear push, thus facilitating machine tool layout. An adjusting screw allows adjustment of the limiting position of the limiting components according to the profile dimensions, enhancing the clamp's flexibility. Attached Figure Description

Detailed Implementation
[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1
[0033] like Figure 3As shown, this specific embodiment provides a general-purpose profile clamp, including a fixed positioning plate 109, a first moving plate 105, a lower moving positioning plate 108, a second moving plate 114, a limiting component 115, and an upper moving positioning plate 107. After clamping, the fixed positioning plate 109 is disposed at the rear of the profile for positioning against the rear surface of the profile. The first moving plate 105 is connected to a drive motor 101 and can be mounted on the worktable of the machine tool 2 via a guide rail. The first moving plate 105 is used for positioning against the front surface of the profile and can move towards and away from the fixed positioning plate 109. The lower moving positioning plate 108 is disposed at the end of the first moving plate 105 near the fixed positioning plate 109. The second moving plate 114 is movably disposed on the upper part of the first moving plate 105 via a guide rail. The moving direction of 14 is the same as the moving direction of the first moving plate 105. To reduce manufacturing costs, a tail plate is provided at the rear of the second moving plate 114 along the moving direction of the second moving plate 114. The rear of the tail plate is connected to the second driving cylinder 113. The limiting component 115 is provided on the first moving plate 105 and located at the front of the tail plate. The limiting component 115 can abut against the tail plate. The extension displacement of the second driving cylinder 113 can be adjusted to any position within its stroke by the limiting component 115, achieving the effect of motor control. The upper moving positioning plate 107 is connected to the first driving cylinder 106. The first driving cylinder 106 is provided on the second moving plate 114. The moving direction of the upper moving positioning plate 107 on the moving seat is the same as the moving direction of the first moving plate 105.
[0034] When clamping the frame, the upper movable positioning plate 107 extends and cooperates with the fixed positioning plate 109 to achieve clamping; when clamping the reinforcing echelon, both the lower movable positioning plate 108 and the upper movable positioning plate 107 (driven by the first driving cylinder 106) extend and cooperate with the fixed positioning plate 109 to achieve clamping. The lower movable positioning plate 108 can effectively prevent the reinforcing echelon from tilting under the action of the upper movable positioning plate 107; when clamping the inward opening fan, both the lower movable positioning plate 108 and the upper movable positioning plate 107 (driven by the second driving cylinder 113) extend and cooperate with the fixed positioning plate 109 to achieve clamping. Through the action of the second driving cylinder 113 and the limiting component 115, the upper movable positioning plate 107 can be stably clamped on one side of the top of the inward opening fan to prevent the inward opening fan from tilting.
[0035] This specific embodiment features a lower moving positioning plate 108 and an upper moving positioning plate 107, each connected to a driving component. The driving component of the upper moving positioning plate 107 is also connected to another driving component, enabling it to move relative to the lower positioning plate. The extension control of the lower moving positioning plate 108 and the upper moving positioning plate 107 can be achieved through the coordinated operation of the various driving components, thereby meeting the clamping requirements of the frame, the reinforcing mullion, and the inward-opening fan profile. This embodiment has a high level of versatility, and since the driving components mostly use cylinders, the manufacturing cost is lower compared to using motors.
[0036] like Figure 3 As shown in this specific embodiment, to improve control accuracy, the drive motor 101 is a servo motor. The drive motor 101 is mounted on the mounting plate 112, which can be bolted to the machine tool 2. To increase torque, a reducer is connected to the output shaft of the drive motor 101. The reducer is mounted on the mounting plate 112, and the output shaft of the reducer is connected to the belt drive assembly 102. The belt drive assembly 102 is connected to the lead screw 103, which is rotatably mounted on the mounting plate 112. A nut seat is provided on the lead screw 103, and a protective sleeve 104 is coaxially connected to the nut seat. The protective sleeve 104 is fitted onto the machine tool 2. On the lead screw 103, the protective sleeve 104 is connected to the rear of the first moving plate 105. Specifically, the nut seat is a nut with a connecting flange, and the connecting flange is bolted to the flange at one end of the protective sleeve 104. The other end of the protective sleeve 104 is provided with a push-pull plate, which is bolted to the first moving plate 105. When the drive motor 101 rotates, it drives the lead screw 103 to rotate, and the lead screw 103 drives the nut seat to move, thereby causing the protective sleeve 104 to push and pull the first moving plate 105 to move. By setting the protective sleeve 104, on the one hand, it transmits power to drive the first moving plate 105 to move, and on the other hand, it can protect the lead screw 103 and the nut seat to avoid the influence of dust and chips.
[0037] like Figure 3 and Figure 5 As shown, since the dimensions of the profiles are not exactly the same, in order to improve the flexibility of the device, the limiting component 115 includes a limiting support 1152 and an adjusting bolt. The limiting support 1152 is set on the first moving plate 105, and the adjusting bolt is horizontally set on the limiting support 1152. The head of the adjusting bolt can abut against the tail plate. By adjusting the distance of the adjusting bolt head extending out of the limiting support 1152, the extension distance of the second drive cylinder 113 can be adjusted, thereby adjusting the relative position of the upper moving positioning plate 107 and the lower moving positioning plate 108 to match the corresponding profile.
[0038] In this specific embodiment, when the first drive cylinder 106 and the second drive cylinder retract, the upper moving positioning plate 107 is located behind the lower moving positioning plate 108, so as to avoid interference when using the lower moving positioning plate 108 for clamping.
[0039] like Figure 3 As shown, this specific embodiment also includes an upper pressing plate 110, which is connected to an upper pressing cylinder 111. The upper pressing plate 110 can press tightly against the upper surface of the profile. Both the upper pressing plate 110 and the upper pressing cylinder 111 can be installed at corresponding positions on the machine tool 2.
[0040] The working process of this fixture is as follows:
[0041] When the clamped profile is a frame, only the fixed positioning plate 109, the upper moving positioning plate 107, and the upper pressing plate 110 participate in the clamping. The operation process is as follows: the first drive cylinder 106 controls the upper moving positioning plate 107 to extend and cooperate with the fixed positioning plate 109 for clamping. Then, the upper pressing plate 110 is pressed tightly against the upper surface of the profile under the action of the upper pressing cylinder 111. When the profile is relatively narrow, the stroke of the first drive cylinder 106 may be insufficient. At this time, the drive motor 101 is activated, causing the first moving plate 105 to move closer to the profile and shorten the moving distance of the upper moving positioning plate 107.
[0042] When the clamping profile is a reinforced mullion, the fixed positioning plate 109, the upper moving positioning plate 107, the lower moving positioning plate 108, and the upper pressing plate 110 participate in the clamping. The operation process is as follows: the drive motor 101 first controls the lower moving positioning plate 108 to move a set distance L1, so that the lower moving positioning plate 108 contacts the lower part of the surface of the lower section 403 of the reinforced mullion. Then, the first drive cylinder 106 is activated, which drives the upper moving positioning plate 107 to extend and abut against the upper part of the surface of the lower section 403 of the reinforced mullion. The lower moving positioning plate 108 plays the role of preventing tipping. Then, the upper pressing plate 110 is pressed tightly against the upper surface of the profile under the action of the upper pressing cylinder 111.
[0043] When the clamped profile is an inward-opening fan, the fixed positioning plate 109, the upper moving positioning plate 107, the lower moving positioning plate 108, and the upper pressing plate 110 participate in the clamping. The operation process is as follows: the drive motor 101 first controls the lower moving positioning plate 108 to move a set distance L2, so that the lower moving positioning plate 108 contacts the lower part of the column surface of the inward-opening fan, and the arc surface of the lower crossbeam 303 abuts against the fixed positioning plate 109. Then, the second drive cylinder 113 is activated, pushing the upper moving positioning plate 107 to extend until the tail plate abuts against the limit bolt 1151. At this time, the upper moving positioning plate 107 abuts against the outer surface of the upper crossbeam 302 of the inward-opening fan. Then, the upper pressing plate 110 is pressed tightly against the upper surface of the profile under the action of the upper pressing cylinder 111. The extension distance of the head of the limit bolt 1151 is adjusted according to the distance between the outer surface of the upper crossbeam 302 of the inward-opening fan and the outer surface of the column 301.
[0044] When the clamped profile is an irregularly shaped part and cannot be clamped by the upper moving positioning plate 107, the lower moving positioning plate 108 and the upper pressing plate 110 participate in the clamping. The action process is as follows: the drive motor 101 first controls the lower moving positioning plate 108 to move a set distance L3, the drive motor 101 enters the torque control mode, and when the torque increases to the set value, the lower moving positioning plate 108 abuts against the profile. Specific Implementation Method Two
[0046] like Figure 4 and Figure 5 As shown, this specific embodiment provides a profile clamp, which is basically the same in structure as the first specific embodiment, except that: a hinge seat is provided on the mounting plate 112, which is used to connect with the machine tool 2; a push-pull plate is provided at the end of the protective sleeve 104, and the push-pull plate is connected to the first moving plate 105 through a pin; through the hinge seat and the pin, the laying direction of the lead screw 103 can be at a certain angle with the moving direction of the first moving plate 105, so that the protective sleeve 104 does not need to push the first moving plate 105 directly along the moving direction, thus avoiding the profile clamp occupying a large space in the moving direction and affecting the spatial layout of the machine tool 2, especially when other devices are provided on one side of the machine tool 2.
[0047] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:
[0048] 1. By setting a lower moving positioning plate 108 and an upper moving positioning plate 107 respectively connected to driving components, and the driving component of the upper moving positioning plate 107 is also connected to another driving component, it can move relative to the lower positioning plate. The extension control of the lower moving positioning plate 108 and the upper moving positioning plate 107 can be met through the coordinated cooperation of various driving components, thereby meeting the clamping requirements of the frame, the reinforcing mullion and the inward opening fan profile. It has a high degree of versatility and mostly uses cylinders for driving, which has a lower manufacturing cost compared to using a motor.
[0049] 2. By setting the protective sleeve 104, on the one hand, the power is transmitted to drive the first moving plate 105 to move, and on the other hand, the lead screw 103 and nut seat are protected to avoid the influence of dust and chips.
[0050] 3. The power of the drive motor 101 is transmitted to the first moving plate 105 through the hinge and pin mechanism. Compared with the linear push method, it saves space in the moving direction and facilitates the spatial layout of the machine tool 2.
[0051] 4. By setting an adjusting screw, the limiting position of the limiting component can be adjusted according to the size of the profile, improving the flexibility of this fixture.
[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
