Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of steel plate positioning technology. Specifically, it relates to a steel plate positioning fixture for laser cutting processing. Background Technology

[0002] Laser cutting technology, as a high-precision and high-efficiency modern processing method, has been widely used in the cutting and forming of metal sheets. In actual production operations, the steel sheet to be cut needs to be quickly and accurately fixed on the processing table by a positioning fixture to ensure the accuracy of the cutting path and the stability of the processing.

[0003] Currently, most common steel plate positioning fixtures are fixed. Although fixed fixtures have a simple structure, they are only suitable for batch processing of steel plates of a single specification. When the workpiece size or cutting pattern changes, the entire fixture needs to be replaced or reinstalled. The adjustment process is cumbersome and time-consuming, which seriously affects production efficiency.

[0004] Therefore, existing steel plate positioning fixtures suffer from a single adjustable dimension and insufficient adjustment flexibility. Hence, a positioning fixture solution with multi-dimensional adjustment is provided to solve the above-mentioned technical problems. Utility Model Content

[0009] Furthermore, the push rod is a hydraulic push rod or an electric push rod. When the push rod is fully retracted, the inner surface of the positioning block abuts against the front end face of the bottom block and the front end face of the movable block, respectively, to limit the axial displacement of the movable block.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the hydraulic or electric actuator can control the lateral position of the positioning block, improve the convenience of adjustment, and when the actuator retracts, the positioning block abuts against the bottom block and the movable block, restricting the axial displacement of the movable block, preventing accidental movement, and enhancing the positioning stability.

[0011] Furthermore, the vertical adjustment assembly includes a drive motor and a threaded rod. The drive motor is mounted on the top of the movable block by screws, and the threaded rod is connected to the output end of the drive motor. The threaded rod passes through the movable block and the bottom block and is threadedly engaged with the movable block.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the drive motor provides power, and the vertical precise movement of the movable block is realized through the threaded rod transmission, thereby realizing the adjustment of the steel plate height and improving the accuracy and efficiency of vertical positioning.

[0013] Furthermore, at least two limiting blocks are circumferentially provided at the bottom end of the threaded rod, and a limiting groove for the limiting block to rotate is opened inside the bottom block, and a sealing plug is provided at the bottom of the limiting groove.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the limiting block and the limiting groove cooperate to prevent the threaded rod from coming out, thereby improving safety; the sealing plug prevents dust and debris from entering, thereby protecting the internal mechanism and extending its service life.

[0015] Furthermore, the vertical adjustment component also includes a guide post, and a guide hole is provided near the rear end of the movable block to slide with the guide post.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by sliding the guide post with the guide hole, it is ensured that the moving block maintains a straight line when moving vertically, preventing skew or rotation, and improving the smoothness of adjustment and positioning accuracy.

[0017] Furthermore, both the upper and lower ends of the guide post are connected to abutment plates by screws, wherein the lower abutment plate is threadedly engaged with the bottom block, and the upper abutment plate is movably connected to the movable block.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the fixing strength of the guide column is enhanced by the baffle plate, the overall rigidity is improved, the lower baffle plate and the bottom block are threaded together to ensure a firm fit, and the upper baffle plate is movably connected to the movable block to prevent the movable block from falling out of the guide column.

[0019] Furthermore, a pad is connected to the inner side of the positioning block by screws, and the pad is steel with rubber wrapped on the outside.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the steel part of the pad provides sufficient strength, and the rubber wrapping layer increases friction and buffers clamping force, which can effectively fix the steel plate and prevent scratches on the surface of the steel plate, thus protecting the quality of the workpiece.

[0021] Furthermore, the bottom of the base block is provided with a slider that slides with the track, and threaded holes are provided on the bottom of the slider and inside the track.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the steel plate clamp can move laterally along the worktable through the slider and the track, which is convenient to adapt to the clamping requirements of steel plates of different sizes. The threaded hole is used to fix the slider, ensuring the stability of the clamp position during the processing and improving adaptability.

[0023] Furthermore, the upper surface of the processing workbench is provided with at least two parallel tracks, and two or more steel plate clamps are slidably arranged on each track.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the multi-track and multi-clamp design allows multiple steel plates or large steel plates to be fixed at the same time, enhancing processing flexibility; the parallel arrangement ensures synchronous movement of the clamps, improving overall positioning accuracy and processing efficiency.

[0029] like Figure 1-5As shown, this utility model provides a steel plate positioning fixture for laser cutting processing, including a laser cutting processing table 1, a track 2 installed on the upper surface of the processing table 1, and a plurality of steel plate clamps 3 arranged on the upper surface of the processing table 1. Each steel plate clamp 3 includes a base block 31 and a movable block 32. A positioning block 33 is arranged opposite to the front end of the base block 31 and the movable block 32. A horizontal adjustment component 4 is arranged between the positioning block 33 and the base block 31 and the movable block 32, and a vertical adjustment component 5 is arranged between the base block 31 and the movable block 32.

[0030] In use, according to the size and cutting pattern of the steel plate to be processed, the layout of the steel plate clamp 3 is planned in advance. Loosen the fixing screws at the bottom of the slider 35, slide each steel plate clamp 3 along the track 2 on the workbench to the predetermined position, and lock it from below through the threaded holes on the track 2 and the slider 35 to complete the overall positioning adjustment. The steel plate is hoisted and can be manually transported to the multiple clamps that have been positioned. Start the drive motor 51 of the vertical adjustment component 5. The drive motor 51 drives the threaded rod 52 to rotate. Since the threaded rod 52 is threadedly engaged with the movable block 32, and the limiting block 56 at its bottom end is rotated and constrained in the limiting groove 57 of the bottom block 31, the movable block 32 slides along the guide column 53 through the guide hole 54, thereby driving the movable block 32 to rise and fall smoothly until the opening between the upper and lower positioning blocks 33 is slightly larger than the thickness of the steel plate. Activate the hydraulic or electric push rod 41 of the lateral adjustment component 4. The push rod 41 pushes the positioning block 33 to move towards the steel plate. The telescopic rod 42 keeps the synchronous guidance, so that the pad 34 on the inner side of the upper and lower positioning blocks 33 gradually contacts and presses the surface of the steel plate. The stroke of the upper and lower push rods 41 can be independently controlled according to the flatness of the steel plate to achieve reliable clamping. During the cutting process, the positioning fixture remains locked. When it is necessary to adjust the local position of the steel plate or replace the workpiece, the push rod 41 of the corresponding fixture can be controlled individually to fine-tune the clamping position, or the slider 35 screw can be loosened to move the entire fixture for rearrangement. After processing is completed, the push rod 41 retracts, driving the positioning block 33 to retract. When the push rod 41 is fully retracted, the inner side of the positioning block 33 abuts against the bottom block 31 and the front end face of the movable block 32; the drive motor 51 reverses to lift the movable block 32, and the steel plate can be unloaded. If the clamping range needs to be changed or maintenance is required, the sealing plug 58 at the bottom of the limiting groove 57 of the bottom block 31 can be pulled out, and the threaded rod 52 together with the guide post 53 can be taken out from below. After replacing the rod with one of appropriate length, it can be reinstalled and sealed to achieve adjustment and maintenance of the clamp stroke.

[0031] In the above technical solution, the lateral adjustment component 4 includes a push rod 41 and a telescopic rod 42. The front ends of the bottom block 31 and the movable block 32 are provided with mounting holes 43 for installing the push rod 41 and the telescopic rod 42. The rear ends of the push rod 41 and the telescopic rod 42 are screwed to the positioning block 33. The telescopic rod 42 is synchronously extended and retracted by the extension and retraction of the push rod 41, thereby adjusting the position of the positioning block 33 on the bottom block 31 and the movable block 32.

[0032] It should be noted that the push rods 41 on the two positioning blocks 33 do not need to be started synchronously to keep in line with each other to position the steel plate. The upper and lower positioning points can be selected to correspond depending on the condition of the steel plate. Furthermore, the telescopic rod 42 includes a sleeve connected to the positioning block 33 and a movable rod that slides with the sleeve and is connected to the bottom block 31 and the movable block 32 to achieve telescopic movement.

[0033] Furthermore, in the above technical solution, the push rod 41 is a hydraulic push rod 41 or an electric push rod 41. When the push rod 41 is fully retracted, the inner surface of the positioning block 33 abuts against the front end face of the bottom block 31 and the front end face of the movable block 32, respectively, so as to limit the axial displacement of the movable block 32. The position of the positioning block 33 is controlled by the extension and retraction of the push rod 41.

[0034] Furthermore, in the above technical solution, the vertical adjustment component 5 includes a drive motor 51 and a threaded rod 52. The drive motor 51 is installed on the top of the movable block 32 by screws. The threaded rod 52 is connected to the output end of the drive motor 51. The threaded rod 52 passes through the movable block 32 and the bottom block 31 and is threadedly engaged with the movable block 32. The drive motor 51 provides power to the threaded rod 52. The rotation of the threaded rod 52 controls the lifting and lowering of the movable block 32 relative to the bottom block 31, so as to adjust the clamping size of the steel plate clamp 3.

[0035] Furthermore, in the above technical solution, at least two limiting blocks 56 are circumferentially provided at the bottom end of the threaded rod 52. The bottom block 31 has a limiting groove 57 for the limiting blocks 56 to rotate. The limiting blocks 56 cooperate with the limiting groove 57 to allow the threaded rod 52 to rotate in the bottom block 31 and connect with the bottom block 31, restricting the position of the threaded rod 52 and preventing the threaded rod 52 from coming out of the bottom block 31. A sealing plug 58 is provided at the bottom of the limiting groove 57. The sealing plug 58 is made of rubber. When it is necessary to replace the threaded rod 52 with a longer / shorter length, the sealing plug 58 can be pulled out and the threaded rod 52 can be extended and removed from the bottom block 31. The new threaded rod 52 passes through the bottom block 31 and then through the movable block 32 to connect with the drive motor 51.

[0036] Furthermore, in the above technical solution, the vertical adjustment component 5 also includes a guide post 53, and a guide hole 54 is provided near the rear end of the movable block 32 to slide and cooperate with the guide post 53. The movement of the movable block 32 is stabilized by the cooperation between the guide post 53 and the guide hole 54.

[0037] Furthermore, in the above technical solution, both the upper and lower ends of the guide post 53 are connected to abutment plates 55 by screws. The lower abutment plate 55 is threadedly engaged with the bottom block 31, and the upper abutment plate 55 is movably connected to the movable block 32. The position of the guide post 53 is fixed by the lower abutment plate 55, and the movable block 32 is prevented from coming off the guide post 53 by the upper abutment plate 55. When the threaded rod 52 is replaced, the guide post 53 is also replaced at the same time to ensure that the stroke of the guide post 53 and the threaded rod 52 are consistent.

[0038] Furthermore, in the above technical solution, the inner side of the positioning block 33 is connected to a pad 34 by screws. The pad 34 is steel with rubber wrapped around its outer surface. The design of the pad 34 optimizes the clamping part of the steel plate clamp 3, avoiding direct contact between the positioning block 33 and the steel plate. By adopting a composite structure with steel as the core and rubber as the coating, the rubber layer undergoes elastic deformation under the action of clamping force. This not only increases the anti-slip ability by increasing the friction coefficient, but also reduces the pressure on the surface of the steel plate by stress distribution, thus avoiding indentation.

[0039] Furthermore, in the above technical solution, the bottom of the base block 31 is provided with a slider 35 that slides with the track 2. Threaded holes are opened in the bottom of the slider 35 and in the track 2. The slider 35 allows the steel plate clamp 3 to be adjusted and installed on the processing worktable 1, and the position is fixed by screws from the bottom surface of the processing worktable 1, which facilitates the position adjustment of the steel plate clamp 3 to adapt to different steel plates to be processed.

[0040] Furthermore, in the above technical solution, the upper surface of the processing workbench 1 is provided with at least two parallel tracks 2, and each track 2 is slidably provided with two or more steel plate clamps 3. The design of multiple tracks 2 makes the adjustment of the steel plate clamps 3 more diversified.

[0041] It should be noted that the installation of multiple tracks 2 requires ensuring that there is no conflict between the tracks 2, and when it is necessary to remove the steel plate clamp 3, the steel plate clamp 3 should be manually slid to the end of the track 2 and then slid out.

[0042] Specifically, the principle of this utility model is as follows: The core of this utility model lies in integrating the independent movement adjustment in the horizontal and vertical directions and the overall position into the steel plate clamp 3, and achieving stable positioning of the steel plate through the coordinated action of transmission, guidance and limiting mechanisms. In the lateral adjustment assembly 4, the linear thrust of the push rod 41 is transmitted to the positioning block 33 via the rigid guide of the telescopic rod 42, causing the positioning block 33 to produce a controllable radial displacement. When the push rod 41 retracts to its limit, the inner side of the positioning block 33 forms a surface contact hard limit with the bottom block 31 and the front end face of the movable block 32. The mechanical interference prevents any accidental movement of the movable block 32 in the axial direction, ensuring the certainty of the clamping reference. In the vertical adjustment assembly 5, the drive motor 51 drives the threaded rod 52 to rotate. Since the threaded rod 52 is threadedly engaged with the movable block 32, and its bottom end is constrained by the circumferentially distributed limit blocks 56 in the limit groove 57 of the bottom block 31, the thread converts the rotational motion into the strict vertical lifting and lowering of the movable block 32. At the same time, the guide post 53 passes through the guide hole 54 of the movable block 32 and slides with it to form over-positioning guidance, effectively suppressing the attitude deflection and swaying of the movable block 32 during the lifting and lowering process. The adjustment process control of horizontal clamping and vertical pressing: First, the vertical component is driven to open the upper and lower positioning blocks 33 to adapt to the thickness of the steel plate. Then, the horizontal component is activated to radially press the positioning blocks 33, realizing step-by-step positioning. The steel plate clamp 3 as a whole slides with the track 2 on the worktable through the bottom slider 35, allowing the steel plate clamp 3 to move along the track 2. Rigid locking is achieved through the threaded connection between the slider 35 and the track 2, thus combining the coarse adjustment and fine adjustment of the clamping of the steel plate clamp 3. The entire structure relies on multiple mechanisms of thread self-locking, mechanical limit and friction locking to maintain the long-term stability of positioning in the vibration environment of laser cutting. The independent adjustability of each steel plate clamp 3 and the mobility on the track 2 make the layout of the clamp group flexible and reconfigurable to adapt to the processing needs of steel plates of different sizes and different cutting paths.

[0043] It is worth noting that the control method in this application is to control the use of components such as the motor and push rod 41 through a controller / remote control. The control circuit of the controller / remote control can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. This application will not explain the control method and circuit connection in detail.
