Description

Technical Field

[0001] This utility model relates to the field of guide plate processing technology, and in particular to a component clamping device for guide plates of metallurgical rolling mills. Background Technology

[0002] Rolling mill guide plates are devices used to control the entry and exit of rolled pieces from the rolls. They are usually made of cast iron, but in some small rolling mills, they can also be made of steel. The guide plates can guide the incoming rolled pieces into the correct roll pass and accurately raise them to the required height. In the production process of metallurgical rolling mill guide plates, the guide plates need to be clamped and fixed to facilitate the welding, turning and other processing of the guide plates.

[0003] In existing technologies, I-beam clamps are often used to hold guide plates. This clamping method can only clamp the guide plate from the top and bottom, and cannot effectively limit the side of the guide plate. When the guide plate is being machined or drilled, the workpiece is easily rotated and displaced by the cutting force, which not only affects the machining accuracy, but also causes the machining to be interrupted and the workpiece to be damaged. Furthermore, it is difficult to ensure that the fixed position of different workpieces is consistent when using I-beam clamps, which also affects the machining accuracy.

[0004] Therefore, there is an urgent need to provide a component clamping device for metallurgical rolling mill guide plates to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a component clamping device for metallurgical rolling mill guide plates.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a component clamping device for metallurgical rolling mill guide plates is provided, including a worktable mechanism and a transmission mechanism. At least two gantry mechanisms are fixed on the worktable mechanism, a drive mechanism is provided on the gantry mechanism, a clamping mechanism is fixed on the drive mechanism, and a screw mechanism is provided inside the clamping mechanism.

[0007] The bottom end of the lead screw mechanism is provided with a transmission mechanism for transmitting power and changing the direction of motion.

[0008] One end of the transmission mechanism is fixed with a clamping mechanism for clamping the workpiece.

[0009] The present invention is further configured such that: the workbench mechanism includes a table body, and at least two sliding grooves are provided on the top of the table body.

[0010] The above technical solution uses stainless steel as the platform material, which effectively improves the platform's durability and load-bearing capacity, and can also elevate the workpiece, making it easier for people to process it.

[0011] The present invention is further configured such that: the gantry mechanism includes a frame fixed on the platform, and the inner walls on both sides of the frame are provided with sliding grooves II, and the bottom ends on both sides of the frame are provided with sliding grooves III.

[0012] Through the above technical solution, the gantry mechanism is also made of stainless steel. The slide grooves 2 and 3 on the gantry mechanism can limit the lifting pressure plate and the rack, thereby improving the stability of the moving parts of the device.

[0013] The present invention is further configured such that: the driving mechanism includes a hydraulic cylinder fixed to the top of the frame, the output end of the hydraulic cylinder is fixed with a lifting pressure plate, and both ends of the lifting pressure plate are provided with threaded grooves.

[0014] With the above technical solution, when the hydraulic cylinder extends and retracts, the lifting pressure plate and the threaded groove will rise and fall accordingly. The two ends of the lifting pressure plate are slidably connected to the second sliding groove, which can prevent the lifting pressure plate from deviating and improve the stability of the lifting pressure plate's movement.

[0015] The present invention is further configured such that: the pressing mechanism includes an outer sleeve fixed to the bottom end of the lifting pressure plate, a compression spring is provided inside the outer sleeve, an inner cylinder is connected to the bottom end of the compression spring, a pressure block is fixed to the bottom end of the inner cylinder, and a rubber pad is adhered to the bottom end of the pressure block.

[0016] With the above technical solution, when the hydraulic cylinder extends, the clamping mechanism will move downward. At this time, the pressure block and the rubber pad will come into contact with the workpiece. The pressure spring enables the pressure block to elastically clamp the workpiece, which not only reduces the risk of the workpiece being squeezed and deformed, but also can be applied to workpieces of various specifications. The rubber pad can prevent the workpiece surface from being scratched.

[0017] The present invention is further configured such that: the lead screw mechanism includes a lead screw body threadedly connected to the inside of the lead screw groove, a first rotating connector is provided at the top end of the lead screw body, and a second rotating connector is provided at the bottom end of the lead screw body.

[0018] Through the above technical solution, the top end of the lead screw body is rotatably connected to the frame through a rotating connector one, and the bottom end of the lead screw body is rotatably connected to the platform through a rotating connector two. The lead screw mechanism is provided in two sets, and the thread directions of the lead screw bodies are opposite. When the hydraulic cylinder extends and the thread groove moves downward, the lead screw body will be driven by the thread groove to rotate, and the rotation directions of the two lead screw bodies are opposite.

[0019] The present invention is further configured such that: the transmission mechanism includes a gear fixed to the outside of the lead screw body, and a rack is externally meshed with the gear.

[0020] With the above technical solution, the rack and the slide are slidably connected. When the lead screw body rotates, the gear will also rotate. The gears on the two lead screw bodies can drive the two racks to move towards each other or in opposite directions.

[0021] The present invention is further configured such that: the clamping mechanism includes a clamping block fixed to one end of the rack, and a slider is fixed to the bottom end of the clamping block.

[0022] With the above technical solution, when the two racks move towards each other, the clamping blocks also move towards each other, and the two clamping blocks can clamp the workpiece. When the two racks move in opposite directions, the clamping blocks can release the workpiece. The above structure clamps the workpiece from two directions, which not only makes the workpiece more evenly stressed, but also effectively prevents the workpiece from lateral displacement. The slider is slidably set inside the first groove, which can effectively limit the clamping block and improve the clamping stability of the clamping block.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. This utility model achieves bottom support and bidirectional clamping of the workpiece through the setting of the drive mechanism, lead screw mechanism and transmission mechanism, which makes the clamping more stable, the workpiece is subjected to more uniform force, and can effectively prevent the workpiece from shifting during processing. In addition, the synchronization rate of its two clamping mechanisms is high, and the position of the workpiece is not easily changed when clamping different workpieces.

[0025] 2. This utility model, through the driving mechanism and the clamping mechanism, can press the workpiece down from above during clamping, thereby preventing the workpiece from lifting up during processing. Furthermore, this clamping structure is applicable to workpieces of various thicknesses. Attached Figure Description

Detailed Implementation

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] Please see Figures 1-5 A component clamping device for a metallurgical rolling mill guide plate includes a worktable mechanism 1 and a transmission mechanism 6. The worktable mechanism 1 includes a table body 101, with at least two sliding grooves 102 on the top of the table body 101. The table body 101 is made of stainless steel, which effectively improves the durability and load-bearing capacity of the table body 101 and can raise the workpiece for easy processing. At least two gantry mechanisms 2 are fixed on the worktable mechanism 1. The gantry mechanism 2 includes a frame 201 fixed on the table body 101. Sliding grooves 202 are opened on both inner walls of the frame 201, and sliding grooves 303 are opened on both bottom ends of the frame 201. The gantry mechanism 2 is also made of stainless steel. The sliding grooves 202 and 303 on the gantry mechanism 2 can limit the lifting pressure plate 302 and the rack 602, thereby improving the stability of the moving parts of the device.

[0034] like Figure 3 As shown, the gantry mechanism 2 is equipped with a drive mechanism 3. The drive mechanism 3 includes a hydraulic cylinder 301 fixed to the top of the frame 201. The output end of the hydraulic cylinder 301 is fixed with a lifting pressure plate 302. Both ends of the lifting pressure plate 302 are provided with threaded grooves 303. When the hydraulic cylinder 301 extends or retracts, the lifting pressure plate 302 and the threaded grooves 303 will rise or fall accordingly. Both ends of the lifting pressure plate 302 are slidably connected to the sliding groove 202, which can prevent the lifting pressure plate 302 from shifting and improve the stability of the lifting pressure plate 302's movement.

[0035] like Figure 1 , Figure 3 and Figure 5As shown, a pressing mechanism 4 is fixed on the drive mechanism 3. The pressing mechanism 4 includes an outer sleeve 401 fixed to the bottom end of the lifting pressure plate 302. A compression spring 402 is provided inside the outer sleeve 401. An inner cylinder 403 is connected to the bottom end of the compression spring 402. A pressing block 404 is fixed to the bottom end of the inner cylinder 403. A rubber pad 405 is glued to the bottom end of the pressing block 404. When the hydraulic cylinder 301 extends, the pressing mechanism 4 will move downward. At this time, the pressing block 404 and the rubber pad 405 will contact the workpiece. The compression spring 402 enables the pressing block 404 to elastically press the workpiece, which can not only reduce the risk of the workpiece being squeezed and deformed, but also be applicable to workpieces of various specifications. The rubber pad 405 can prevent the surface of the workpiece from being scratched.

[0036] like Figure 3 and Figure 4 As shown, a screw mechanism 5 is provided inside the clamping mechanism 4. The screw mechanism 5 includes a screw body 501 threadedly connected to the inside of the screw groove 303. A rotating connector 502 is provided at the top of the screw body 501, and a rotating connector 503 is provided at the bottom of the screw body 501. The top of the screw body 501 is rotatably connected to the frame 201 through the rotating connector 502, and the bottom of the screw body 501 is rotatably connected to the platform 101 through the rotating connector 503. There are two sets of screw mechanisms 5, and the thread directions of their screw bodies 501 are opposite. When the hydraulic cylinder 301 extends and the screw groove 303 moves downward, the screw body 501 will be driven by the screw groove 303 to rotate, and the rotation directions of the two screw bodies 501 are opposite.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the bottom end of the lead screw mechanism 5 is provided with a transmission mechanism 6 for transmitting power and changing the direction of motion. The transmission mechanism 6 includes a gear 601 fixed to the outside of the lead screw body 501. The gear 601 is externally meshed with a rack 602. The rack 602 is slidably connected to the slide groove 203. When the lead screw body 501 rotates, the gear 601 will also rotate. The gears 601 on the two lead screw bodies 501 can drive the two racks 602 to move towards each other or in opposite directions.

[0038] like Figure 1 , Figure 3 and Figure 4As shown, a clamping mechanism 7 for clamping workpieces is fixed at one end of the transmission mechanism 6. The clamping mechanism 7 includes a clamping block 701 fixed to one end of the rack 602. A slider 702 is fixed to the bottom end of the clamping block 701. When the two racks 602 move towards each other, the clamping blocks 701 also move towards each other. The two clamping blocks 701 can clamp the workpiece. When the two racks 602 move in opposite directions, the clamping blocks 701 can release the clamping of the workpiece. The above structure clamps the workpiece from two directions, which not only makes the workpiece more evenly stressed, but also effectively prevents the workpiece from lateral displacement. The slider 702 is slidably disposed inside the slide groove 102, which can effectively limit the clamping block 701 and improve the clamping stability of the clamping block 701.

[0039] When using this utility model, the operator first places the workpiece between the clamping blocks 701, and then opens the hydraulic cylinder 301. At this time, the lifting pressure plate 302 moves down, and the screw mechanism 5 and the transmission mechanism 6 drive the clamping mechanism 7 to clamp the workpiece from both sides. At the same time, the pressing mechanism 4 will also press the workpiece from the top, thereby stably clamping the workpiece. The gantry mechanism 2 and the clamping mechanism 7 are both provided with at least two sets, so that the device can stably clamp even long workpieces.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
