Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sofa production equipment, in particular to an iron frame moving fixture. Background Art
[0002] In the current production line of sofa iron frames, the fixtures for clamping iron frames generally use limit blocks to control the clamping position and stability of the iron frames. In traditional fixture designs, the limit blocks are usually set at the same height to adapt to most standardized iron frame structures. However, the structures of sofa iron frames are diverse, especially the heights of crossbars (such as synchronous bars, structural bars, etc.) vary significantly, which brings many inconveniences to the clamping process.
[0003] Taking the crossbars commonly found in sofa iron frames as an example, there is a large height difference between the crossbar near the backrest at one end and the crossbar near the footrest at the other end. When using a fixture with limit blocks at the same height for clamping, the following problems will occur:
[0004] During the clamping process, first, the limit block on one side contacts the crossbar at a lower height, and then it is necessary to drive the crossbar and the connected part of the iron frame upward by mechanical force until the limit block on the other side contacts the crossbar at a higher height. During this process, the iron frame is prone to unnecessary rotation or tilting, affecting the accuracy and stability of clamping, resulting in an unstable clamping process. Based on the instability of the clamping process, safety accidents may also occur, such as the iron frame falling off, colliding, etc., posing potential threats to operators and equipment. Summary of the Utility Model
[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides an iron frame moving fixture, which can solve the problem of unstable clamping caused by the same height of the limit blocks during the iron frame clamping process.
[0006] The technical solution adopted by the utility model to solve its problems is:
[0007] An iron frame moving fixture, comprising:
[0008] A structural plate;
[0009] A first clamping arm, one end of the first clamping arm is connected with a first telescopic device, and the other end is provided with a first clamping jaw;
[0010] A second clamping arm, one end of the second clamping arm is connected with a second telescopic device, and the other end is provided with a second clamping jaw;
[0011] Among them, the first telescopic device and the second telescopic device are respectively arranged on opposite sides of the structural plate. The first clamping jaw is provided with a first limiting block protruding towards the second clamping jaw, and the second clamping jaw is provided with a second limiting block protruding towards the first clamping jaw. The height where the first limiting block is located is higher than the height where the second limiting block is located.
[0012] By adopting the above scheme, by designing that the first limiting block and the second limiting block are located at different heights respectively, this fixture can accurately adapt to the situation where there is a large height difference in the cross bars in the sofa iron frame. This design ensures that no matter how the structure of the iron frame changes, especially when the heights of the cross bars are inconsistent, the fixture can effectively clamp and stably fix the iron frame, avoiding the problems caused by the fixed height of the limiting block in traditional fixtures. The stable clamping process reduces the risk of safety accidents such as the iron frame falling off and colliding, providing a safer working environment for operators and equipment.
[0013] Furthermore, the structural plate is provided with a first guiding member connected to the first clamping arm, and / or the structural plate is provided with a second guiding member connected to the second clamping arm.
[0014] By adopting the above scheme, the existence of the first guiding member provides precise path and direction control for the movement of the first clamping arm. This ensures that the first clamping jaw can move along a predetermined trajectory when clamping the iron frame, avoiding the problem of inaccurate clamping caused by the shaking or deviation of the first clamping arm, thereby improving the accuracy and reliability of clamping. The function of the second guiding member on the second clamping arm is the same as that of the first guiding member on the first clamping arm, which will not be elaborated here.
[0015] Furthermore, there are two first guiding members, and the two first guiding members are arranged on both sides of the first telescopic device and are both parallel to the first telescopic device, and / or there are two second guiding members, and the two second guiding members are arranged on both sides of the second telescopic device and are both parallel to the second telescopic device.
[0016] By adopting the above scheme, the two first guiding members are respectively located on both sides of the first telescopic device, providing more stable and balanced guiding support for the movement of the first clamping arm. It can effectively prevent the clamping arm from swaying or twisting during the movement, so as to ensure that the clamping jaw can accurately reach the predetermined position, improving the stability and accuracy of clamping. The auxiliary effect of the two second guiding members on the second telescopic device is the same as that of the first guiding members on the first telescopic device, which will not be elaborated here.
[0017] Furthermore, the first clamping jaw is detachably connected to the first clamping arm, and / or the second clamping jaw is detachably connected to the second clamping arm.
[0018] By adopting the above solution, different iron frames require first clamps or second clamps with different height differences, shapes, sizes or materials to ensure stable clamping. Through the detachable connection design, users can easily replace clamps of different specifications to adapt to the clamping needs of various iron frames, thereby enhancing the adaptability and flexibility of the clamp.
[0019] Further, the first clamping arm and the first clamping jaw are detachably connected via a first clamping plate assembly, and / or the second clamping arm and the second clamping jaw are detachably connected via a second clamping plate assembly.
[0020] By adopting the above scheme, the first clamp arm and the first clamp jaw are detachably connected by the first clamp plate assembly, which has a better fixing effect when the first clamp jaw is in use and facilitates the disassembly of the first clamp jaw. The second clamp plate assembly has the same beneficial effect on the second clamp arm and the second clamp jaw, which will not be repeated here.
[0021] Further, the first telescopic device includes a first driving member and a first telescopic rod, the first driving member is fixedly mounted on the structural plate, one end of the first telescopic rod is transmission-connected to the first driving member, and the other end is connected to the first clamping arm;
[0022] And / or, the second telescopic device includes a second driving member and a second telescopic rod, the second driving member is fixedly mounted on the structural plate, two ends of the second telescopic rod are transmission-connected to the second driving member, and the other two ends are connected to the second clamping arm.
[0023] Furthermore, the structural plate is provided with a first baffle in a direction facing away from the first driving member connected to the first telescopic rod, and the first baffle abuts against the first driving member;
[0024] And / or, the structural plate is provided with a second baffle in a direction away from the second driving member connected to the second telescopic rod, and the second baffle abuts against the second driving member.
[0025] By adopting the above scheme, the first baffle plate can provide certain support for the first driving member to prevent the first driving member from tilting due to the reaction force of the first telescopic rod during long-term use, thereby ensuring the stability of the first driving member. More importantly, when the first clamp grasps the iron frame, the first clamp arm is connected to the structural plate through the first telescopic rod and the first driving member in sequence, which causes the first driving member to be subjected to a large pulling force. Therefore, the first baffle plate can provide support for the first driving member to prevent the first driving member from tilting or even being disconnected from the structural plate. The effect of the second baffle plate on the second driving member is the same as that of the first baffle plate on the first driving member, which will not be repeated here.
[0026] Furthermore, the first clamping jaw is provided with N first weight-reducing grooves on a side facing the first limit block, and the N first weight-reducing grooves divide the first clamping jaw into (N+1) first forks, and each of the first forks is connected to the first limit block;
[0027] And / or, the second clamping jaw is provided with N second weight reducing grooves on both sides facing the second limiting block, the N second weight reducing grooves divide the second clamping jaw into (N+1) second forks, and each of the second forks is connected to the second limiting block.
[0028] By adopting the above solution, the design of the first weight-reducing groove significantly reduces the weight of the first clamping jaw, making the entire clamp lighter during movement and clamping, reducing energy consumption and mechanical burden. This is of great significance for improving production efficiency, reducing equipment wear and extending service life. The second weight-reducing groove has the same effect on the second clamping jaw, which will not be elaborated here.
[0029] Further, the first limiting block is detachably connected to the first clamping jaw, and / or the second limiting block is detachably connected to the second clamping jaw.
[0030] By adopting the above solution, different iron frames may require first limit blocks and / or second limit blocks of different shapes, sizes or positions to ensure stable clamping. Through the design of detachable connection, users can easily replace limit blocks of different specifications and types to meet the clamping requirements of various iron frames. This flexibility enhances the adaptability and versatility of the clamp, enabling it to be used in a variety of scenarios. In addition, when the first limit block or the second limit block needs to be replaced due to wear, damage or the need to adapt to iron frames of different sizes, the detachable connection design allows the user to easily remove and replace the limit blocks separately without disassembling the entire first clamp or the second clamp. This greatly simplifies the maintenance process, reduces downtime, and reduces maintenance costs.
[0031] Furthermore, the structural plate is provided with a transition structure on the surface opposite to the surface connected to the first telescopic device.
[0032] By adopting the above solution, it is convenient to connect the structural plate with a single-axis, double-axis, or three-axis transmission mechanism or a transmission structure such as a manipulator.
[0033] In summary, the iron frame mobile clamp provided by the utility model has the following technical effects:
[0034] 1. By setting the height difference of the limit block to correspond to the height difference of the two cross bars of the iron frame to be grasped, the clamp can accurately adapt to the cross bars of different heights, and then accurately grasp the iron frame, ensuring the stability and reliability of the clamping;
[0035] 2. The stable gripping of the iron rack by the fixture further reduces the risk of safety accidents such as the iron rack falling off and colliding. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Unless otherwise defined, 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 utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.
[0042] Refer to Figure 1, the present utility model discloses an iron frame moving fixture, which includes a structural plate 1, a first clamping arm 2 and a second clamping arm 3. One end of the first clamping arm 2 is connected with a first telescopic device 21, and the other end is provided with a first clamping jaw 22; one end of the second clamping arm 3 is connected with a second telescopic device 31, and the other end is provided with a second clamping jaw 32; wherein, the first telescopic device 21 and the second telescopic device 31 are respectively arranged on opposite sides of the structural plate 1. The first clamping jaw 22 is provided with a first limiting block 221 protruding towards the second clamping jaw 32, and the second clamping jaw 32 is provided with a second limiting block 321 protruding towards the first clamping jaw 22. The height where the first limiting block 221 is located is higher than the height where the second limiting block 321 is located.
[0043] Specifically, the structural plate 1 is used to connect with a driving device for driving the fixture, such as a single-axis, double-axis, three-axis transmission device or a manipulator, etc., which is not limited herein. One end of the first clamping arm 2 is connected with a first telescopic device 21, and the other end is provided with a first clamping jaw 22. The first telescopic device 21 is used to drive the first clamping arm 2 to move closer to or away from the second clamping arm 3. One end of the first clamping jaw 22 is connected with the first clamping arm 2, and the other end is connected with a first limiting block 221. The first limiting block 221 protrudes from the first clamping jaw 22 towards the second clamping arm 3 for hooking the cross bar at one end of the iron frame. One end of the second clamping arm 3 is connected with a second telescopic device 31, and the other end is provided with a second clamping jaw 32. The second telescopic device 31 is used to drive the second clamping arm 3 to move closer to or away from the first clamping arm 2. One end of the second clamping jaw 32 is connected with the second clamping arm 3, and the other end is connected with a second limiting block 321. The second limiting block 321 protrudes from the second clamping jaw 32 towards the first clamping arm 2 for hooking the cross bar at the other end of the iron frame. The first telescopic device 21 and the second telescopic device 31 are respectively arranged on opposite sides of the structural plate 1. The height where the first limiting block 221 is located is higher than the height where the second limiting block 321 is located, that is, there is a height difference between the first limiting block 221 and the second limiting block 321. The specific value of the height difference can be adjusted correspondingly according to the height difference of the cross bar that needs to be hooked on the iron frame during specific production.
[0044] The working principle of the above structure:
[0045] The iron frame is driven by the assembly line to directly below the fixture. The first telescopic device 21 and the second telescopic device 31 operate, causing the first clamping arm 2 and the second clamping arm 3 to move away from each other, so as to increase the distance between the first limiting block 221 and the second limiting block 321. The fixture moves downward relative to the iron frame, and at the same time drives the first limiting block 221 and the second limiting block 321 to straddle the cross bar to be hooked in the height direction. The first telescopic device 21 and the second telescopic device 31 operate, causing the first clamping arm 2 and the second clamping arm 3 to move relative to each other, so as to reduce the distance between the first limiting block 221 and the second limiting block 321, so that the cross bar to be hooked will be correspondingly located on the upward movement path of the first limiting block 221 and the second limiting block 321, thus completing the clamping of the iron frame.
[0046] The first telescopic device 21 and the second telescopic device 31 in the above structure can be telescopic devices such as cylinders, hydraulic cylinders, telescopic rods, lead screws, etc., and are not limited herein.
[0047] In some embodiments, in order to improve the movement accuracy of the first clamping arm 2 and / or the second clamping arm 3, the structural plate 1 is provided with a first guiding member 23 connected to the first clamping arm 2. Correspondingly, the guiding direction of the first guiding member 23 is the same as the guiding direction of the first telescopic device 21, and / or the structural plate 1 is provided with a second guiding member 33 connected to the second clamping arm 3, and the guiding direction of the second guiding member 33 is the same as the guiding direction of the second telescopic device 31. The presence of the first guiding member 23 provides precise path and direction control for the movement of the first clamping arm 2. This ensures that the first clamping jaw 22 can move along a predetermined trajectory when clamping the iron frame, avoiding the problem of inaccurate clamping caused by the shaking or deviation of the first clamping arm 2, thereby improving the clamping accuracy and reliability. The function of the second guiding member 33 on the second clamping arm 3 is the same as that of the first guiding member 23 on the first clamping arm 2, and will not be elaborated herein.
[0048] The first guiding member 23 and the second guiding member 33 can be the cooperation of a guiding rod and a guiding hole or the cooperation of a sliding groove and a slider, and are not limited herein.
[0049] On the basis of the structure of the first guiding member 23 and / or the second guiding member 33, further, there are two first guiding members 23, and the two first guiding members 23 are arranged on both sides of the first telescopic device 21 and are both parallel to the first telescopic device 21, and / or, there are two second guiding members 33, and the two second guiding members 33 are arranged on both sides of the second telescopic device 31 and are both parallel to the second telescopic device 31. The two first guiding members 23 are respectively located on both sides of the first telescopic device 21, providing more stable and balanced guiding support for the movement of the first clamping arm 2. It can effectively prevent the clamping arm from yawing or twisting during the movement, so as to ensure that the clamping jaw can accurately reach the predetermined position, improving the stability and accuracy of clamping. The auxiliary effect of the two second guiding members 33 on the second telescopic device 31 is the same as that of the first guiding members 23 on the first telescopic device 21, which will not be elaborated here.
[0050] In some embodiments, in order to facilitate the replacement and height adjustment of the first clamping jaw 22 and the second clamping jaw 32, the first clamping jaw 22 is detachably connected to the first clamping arm 2, and / or, the second clamping jaw 32 is detachably connected to the second clamping arm 3. Specifically, since different iron racks require first clamping jaws 22 or second clamping jaws 32 with different height differences, shapes, sizes or materials to ensure stable clamping, through the detachable connection design, users can easily replace clamping jaws of different specifications to adapt to the clamping requirements of various iron racks, enhancing the adaptability and flexibility of the fixture.
[0051] Further, the first clamping arm 2 and the first clamping jaw 22 are detachably connected through a first clamping plate assembly 24, and / or, the second clamping arm 3 and the second clamping jaw 32 are detachably connected through a second clamping plate assembly 34.
[0052] Specifically, the first clamping plate assembly 24 is composed of two plates, clamping the first clamping arm 2 and the first clamping jaw 22 between the two plates, and passing screws through the two plates as well as the first clamping arm 2 and the first clamping jaw 22, so as to achieve detachable connection. The second clamping plate assembly 34 is the same as the first clamping plate assembly 24, which will not be elaborated here.
[0053] In some embodiments, the first telescopic device 21 includes a first driving member 211 and a first telescopic rod 212. The first driving member 211 is fixedly installed on the structural plate 1. One end of the first telescopic rod 212 is in transmission connection with the first driving member 211, and the other end is connected to the first clamping arm 2; and / or, the second telescopic device 31 includes a second driving member 311 and a second telescopic rod 312. The second driving member 311 is fixedly installed on the structural plate 1. One end of the second telescopic rod 312 is in transmission connection with the second driving member 311, and the other end is connected to the second clamping arm 3. Users can select the specific structure of the first telescopic device 21 and the second telescopic device 31 according to needs.
[0054] In some embodiments, in order to enhance the stability of the first driving member 211 and / or the second driving member 311, the structural plate 1 is provided with a first baffle 25 in the direction away from the first driving member 211 where the first telescopic rod 212 is connected, and the first baffle 25 abuts against the first driving member 211, and / or, the structural plate 1 is provided with a second baffle 35 in the direction away from the second driving member 311 where the second telescopic rod 312 is connected, and the second baffle 35 abuts against the second driving member 311.
[0055] Specifically, the first baffle 25 can provide a certain support for the first driving member 211, preventing the first driving member 211 from tilting due to the reaction force of the first telescopic rod 212 during long-term use, and ensuring the stability of the first driving member 211. More importantly, when the first jaw 22 grabs the iron rack, since the first jaw arm 2 is connected to the structural plate 1 through the first telescopic rod 212 and the first driving member 211 in sequence, the first driving member 211 will be subjected to a relatively large pulling force. Therefore, the first baffle 25 is provided to support the first driving member 211 and prevent the first driving member 211 from tilting or even disconnecting from the structural plate 1. The function of the second baffle 35 on the second driving member 311 is the same as that of the first baffle 25 on the first driving member 211, and will not be elaborated here.
[0056] In some embodiments, the first jaw 22 is provided with N first weight-reducing grooves 26 on the side facing the first limiting block 221. The N first weight-reducing grooves 26 divide the first jaw 22 into (N + 1) first fork heads 27, and each first fork head 27 is connected to the first limiting block 221, and / or, the second jaw 32 is provided with N second weight-reducing grooves 36 on the side facing the second limiting block 321. The N second weight-reducing grooves 36 divide the second jaw 32 into (N + 1) second fork heads 37, and each second fork head 37 is connected to the second limiting block 321.
[0057] Specifically, the design of the first weight-reducing grooves 26 significantly reduces the weight of the first jaw 22, making the entire fixture lighter during movement and gripping, reducing energy consumption and mechanical burden. This is of great significance for improving production efficiency, reducing equipment wear and extending service life. The function of the second weight-reducing grooves 36 on the second jaw 32 is the same, and will not be elaborated here.
[0058] In some embodiments, for the convenience of replacing and repairing the first limiting block 221 and the second limiting block 321, the first limiting block 221 is detachably connected to the first jaw 22, and / or the second limiting block 321 is detachably connected to the second jaw 32. Specifically, different iron racks may require first limiting blocks 221 and / or second limiting blocks 321 with different shapes, sizes or positions to ensure stable clamping. Through the design of detachable connection, users can conveniently replace limiting blocks of different specifications and types to adapt to the clamping requirements of various iron racks. This flexibility enhances the adaptability and versatility of the fixture, enabling it to be applied in a variety of scenarios. Additionally, when the first limiting block 221 or the second limiting block 321 needs to be replaced due to wear, damage or the need to adapt to iron racks of different sizes, the detachable connection design allows users to easily disassemble and replace the limiting block individually, without having to disassemble the entire first jaw 22 or second jaw 32. This greatly simplifies the repair process, reduces downtime, and lowers the repair cost.
[0059] In some embodiments, for the convenience of connecting the structural plate 1 to the transmission structure, the structural plate 1 is provided with an adapter structure on the opposite surface of the first telescopic device 21. The adapter structure is a connector capable of quickly connecting to the transmission structure, such as a connecting ear or other structures, which is not limited herein, as long as it can quickly connect to transmission structures such as single-axis, double-axis, three-axis transmission mechanisms or manipulators.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
