Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and more specifically, to a lifting clamping device for a rebar cutter. Background Technology

[0002] During the cutting of reinforcing bars, because the reinforcing bars need to extend outwards, the vibration generated by the cutting device can easily cause the tail of the reinforcing bar to shake significantly during cutting, resulting in an uneven cutting surface. At the same time, the vibration can also cause slight displacement of the reinforcing bar being cut, thus affecting the cutting accuracy. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a lifting and clamping device for a rebar cutting machine, which has the advantages of keeping the cutting surface flat and improving the cutting accuracy.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 5 As shown, this utility model provides a lifting and clamping device for a rebar cutting machine, including a base 1, a support plate 2 fixedly installed on the top of the base 1, a sliding groove 3 inside the support plate 2, a slider 4 slidably connected inside the sliding groove 3, a connecting plate 5 fixedly installed on the right side of the slider 4, a positioning plate 6 fixedly installed on the right side of the connecting plate 5, a sliding groove 7 inside the positioning plate 6, a slider 8 slidably connected inside the sliding groove 7, a clamping block 9 fixedly installed on the outside of the slider 8, and a clamping block 11 fixedly installed on the right side of the positioning plate 6, with the clamping block 11 located above the clamping block 9.

[0016] When it is necessary to clamp and hold the steel bar, first start the motor 14 to drive the lead screw 15 to rotate, so that the lead screw 15 engages with the clamping block 9. At this time, the clamping block 9 will be driven to move up and down through the sliding connection between the slider 8 and the groove 7, so that the clamping block 9 moves closer to the clamping block 11. At the same time, the steel bar will be clamped in the middle of the clamping block 9 and the clamping block 11, thus being fixed. During cutting, there will be no vibration that causes deviation in cutting accuracy.

[0017] Among them, clamping block 19 has a clamping groove 10 inside, clamping block 21 has a clamping groove 22 at the bottom, clamping groove 22 is located above clamping groove 10, and there are three clamping grooves 10 and three clamping grooves 22, which surround each other to form a hollow circle.

[0018] The three clamping slots 10 and 12 clamp the steel bars inside. When cutting, the three steel bars are clamped and fixed at the same time, so that they can be cut at the same time. Since the three steel bars are fixed at the same time, the overall cutting efficiency is improved while keeping the cutting blade flat, thereby increasing the overall production efficiency.

[0019] Among them, a fixing plate 13 is fixedly installed above the positioning plate 6, a motor 14 is fixedly installed above the fixing plate 13, a lead screw 15 is fixedly installed at the output end of the motor 14, and the outer side of the lead screw 15 meshes with the clamping block 9.

[0020] When the motor 14 is started, the lead screw 15 is driven to rotate. At this time, the lead screw 15 will mesh with the clamping block 9, so that the clamping block 9 is driven to move up and down through the slider 8 and the slide groove 7, so as to achieve the effect of conveniently adjusting the position for clamping.

[0021] Among them, a fixing block 17 is fixedly installed above the support plate 2, a cylinder 18 is fixedly installed above the fixing block 17, an output shaft 19 is fixedly installed at the output end of the cylinder 18, a control plate 20 is fixedly installed at the bottom of the output shaft 19, and the control plate 20 is fixedly connected to the slider 4.

[0022] When the cylinder 18 is started, the output shaft 19 moves up and down. At this time, the control plate 20 is driven by the output shaft 19, and the slider 4 slides up and down inside the groove 3. This adjusts the height of the connecting plate 5 and the positioning plate 6, so that the clamping position and the height of the steel bar cutting are horizontal during cutting. This prevents the cutting blade from being uneven due to gravity.

[0023] There are two slides 3 and two sliders 4. The two sliders 4 are slidably connected to each other and are distributed in a front-to-back manner.

[0024] The two sliders 4 are slidably connected to the two slide grooves 3, so that the position of the control plate 20 and the connecting plate 5 is limited to moving up and down when sliding, thus maintaining the overall stability.

[0025] Among them, a limit ring 16 is fixedly installed on the right side of the positioning plate 6, and the lead screw 15 passes through the inside of the clamping block 11 and the limit ring 16 respectively.

[0026] The main function of the limiting ring 16 is to limit the clamping block 9 and prevent the clamping block 9 from falling off during the engagement with the lead screw 15.

[0027] Working principle and usage process of this utility model: First, a positioning plate 6 is fixedly installed on the right side of the connecting plate 5. A second groove 7 is opened inside the positioning plate 6. A second slider 8 is slidably connected inside the second groove 7. A first clamping block 9 is fixedly installed on the outside of the second slider 8. A second clamping block 11 is fixedly installed on the right side of the positioning plate 6. At the same time, the second clamping block 11 is located above the first clamping block 9. When it is necessary to clamp and hold the steel bar, the motor 14 is started to drive the lead screw 15 to rotate, so that the lead screw 15 engages with the first clamping block 9. At this time, the first clamping block 9 will be driven to move up and down through the sliding connection between the second slider 8 and the second groove 7, so that the first clamping block 9 moves closer to the second clamping block 11. At the same time, the steel bar will be held tightly in the middle of the first clamping block 9 and the second clamping block 11, thus being fixed. During cutting, there will be no vibration that causes deviation in cutting accuracy. Secondly, a clamping groove 10 is provided inside the clamping block 9, and a clamping groove 22 is provided at the bottom of the clamping block 21, with the clamping groove 22 located above the clamping groove 10. There are three clamping grooves 10 and 22, which form a hollow circle. The three clamping grooves 10 and 22 clamp the steel bars inside. When cutting, the three steel bars are clamped and fixed at the same time, so that they can be cut at the same time. Since the three steel bars are fixed at the same time, the overall cutting efficiency is improved while keeping the cutting blade flat, thereby increasing the overall production efficiency. Finally, by fixing an output shaft 19 to the output end of the cylinder 18, and fixing a control plate 20 to the bottom of the output shaft 19, and fixing the control plate 20 to the slider 4, the cylinder 18 is started to drive the output shaft 19 to move up and down. At this time, the control plate 20 is driven by the output shaft 19, and the slider 4 slides up and down inside the groove 3, thereby adjusting the height of the connecting plate 5 and the positioning plate 6. Thus, during cutting, the clamping position is horizontal with the height of the rebar cutting, so that the cutting blade is not uneven due to the influence of gravity.
