Description

Technical Field

[0001] This invention relates to the field of steel plate sawing and milling machine technology, and more specifically, to a novel feeding and clamping mechanism for steel plate sawing and milling machines. Background Technology

[0002] The feeding rack is a key auxiliary equipment of the steel plate sawing and milling machine, mainly used to automatically and accurately transport steel plate materials to the processing area.

[0003] Traditionally, manual measurement or simple material conveying methods are used, requiring manual overhead crane loading, which leads to low efficiency and poor accuracy. In addition, manual overhead crane loading has a large impact on the roller frame. At the same time, the surface of the steel plate raw material is uneven, with a flatness tolerance of 3-5mm, which will affect the feeding during clamping. Therefore, a new type of feeding and clamping mechanism for steel plate sawing and milling machines is needed. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a new type of feeding and clamping mechanism for steel plate sawing and milling machines to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A novel feeding and clamping mechanism for a steel plate sawing and milling machine includes a support frame. Multiple sets of roller frames are fixedly connected to the top of the support frame. Rollers arranged at equal intervals are rotatably connected to the inner side of each roller frame. Three linear guide rails are fixedly connected to the top of the support frame. A movable seat is slidably connected to the top of each of the three linear guide rails. A vertical guide rail is fixedly connected to the left side of each of the three movable seats. A floating seat is slidably connected to each of the three vertical guide rails. A clamping mechanism is provided on each of the three floating seats. A drive mechanism is provided on the support frame to drive the three movable seats to translate.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes a cylinder, the fixed end of which is fixedly connected to the floating seat, the telescopic end of which is fixedly connected to a movable clamping plate, and a fixed clamping plate integrally formed on the left side of the floating seat.

[0009] As a further description of the above technical solution:

[0010] The drive mechanism includes two ball screws, both ends of which are rotatably connected to the bracket. Two servo motors are fixedly connected to the right side of the bracket, and the output shafts of the two servo motors are fixedly connected to the two ball screws respectively. The bottom of the front movable seat and the bottom of the back movable seat are respectively sleeved on the two ball screws and mechanically coupled to them. The two back movable seats are detachably connected by bolts.

[0011] As a further description of the above technical solution:

[0012] The top of the bracket is fixedly connected to side blocks arranged at equal intervals, and the front of the side blocks is rotatably connected to pulleys.

[0013] As a further description of the above technical solution:

[0014] Multiple mounting brackets are fixedly connected to the inner side of the bracket, and buffer cylinders are fixedly connected to the mounting brackets.

[0015] As a further description of the above technical solution:

[0016] Both the movable clamping plate and the fixed clamping plate are fixedly connected to a buffer pad on their opposite sides, and both buffer pads have anti-slip textures on their opposite sides.

[0017] As a further description of the above technical solution:

[0018] The top buffer pad is hollow, and a pressure sensor is fixedly connected to the inner bottom wall of the top buffer pad.

[0019] Compared with the prior art, the advantages of this invention are:

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] To address the problem of uneven steel plate surfaces affecting feeding, and the low efficiency and poor precision of traditional steel plate milling machines, this invention provides Embodiment 1:

[0030] Please see Figures 1-5 In this invention: a novel feeding and clamping mechanism for a steel plate sawing and milling machine includes a support 1. Multiple sets of roller frames 2 are fixedly connected to the top of the support 1. Rollers 3 arranged at equal intervals are rotatably connected to the inner side of each roller frame 2. Three linear guide rails 4 are fixedly connected to the top of the support 1. Movable seats 5 are slidably connected to the top of each of the three linear guide rails 4. Vertical guide rails 6 are fixedly connected to the left side of each of the three movable seats 5. Floating seats 7 are slidably connected to each of the three vertical guide rails 6. Clamping mechanisms 8 are provided on each of the three floating seats 7. A driving mechanism 9 for driving the three movable seats 5 to translate is provided on the support 1. The clamping mechanism 8 includes a cylinder 801. The cylinder 801 has a fixed... The fixed end is fixedly connected to the floating seat 7. The telescopic end of the cylinder 801 is fixedly connected to the movable clamping plate 802. The left side of the floating seat 7 is integrally formed with a fixed clamping plate 803. The drive mechanism 9 includes two ball screws 901. Both ends of the two ball screws 901 are rotatably connected to the bracket 1. The right side of the bracket 1 is fixedly connected to two servo motors 902. The output shafts of the two servo motors 902 are fixedly connected to the two ball screws 901 respectively. The bottom of the front movable seat 5 and the bottom of the back movable seat 5 are respectively sleeved on the two ball screws 901 and mechanically coupled to them. The two back movable seats 5 are detachably connected by bolts 903.

[0031] In this invention, the steel plate is located on multiple roller frames 2 at the top of the support 1. Rollers 3 support the steel plate. The right side of the steel plate is located between the movable clamping plate 802 and the fixed clamping plate 803. By opening the cylinder 801, the movable clamping plate 802 can be driven to descend, and the movable clamping plate 802 will move closer to the fixed clamping plate 803 until the movable clamping plate 802 is in close contact with the steel plate, thereby completing the clamping of the steel plate. Since the floating seat 7 is slidably connected to the vertical guide rail 6, the clamping mechanism 8 can float up and down, and has an adaptive function to uneven steel plate surfaces. After the steel plate is stably clamped, the ball screw 901 is driven to rotate by the servo motor 902, and the moving seat 5 will translate along the linear guide rail 4. The servo motor 902 adopts an integrated encoder model, and the distance the moving seat 5 moves can be accurately controlled by the control system to achieve accurate fixed-length feeding.

[0032] Please see Figure 1 The bracket 1 has side blocks 10 arranged at equal intervals fixedly connected to its top, and pulleys 11 are rotatably connected to the front of the side blocks 10.

[0033] When unloading the steel plate onto the top of the roller frame 2, the front and rear positions of the steel plate are difficult to control, affecting the accuracy of the steel plate entering the steel plate sawing and milling machine. To solve this problem, the present invention provides Embodiment 2:

[0034] In this invention, the cooperation between the side stop 10 and the pulley 11 can be used as a reference for unloading the steel plate, preventing the material from tilting and improving the accuracy of the steel plate being fed into the steel plate sawing and milling machine.

[0035] The steel plate is relatively heavy, and when it is unloaded onto the top of the roller frame 2, it will cause a large impact on the roller frame 2, affecting the service life of the device. To solve this problem, the present invention provides Embodiment 3:

[0036] Please see Figure 1 Among them, multiple mounting brackets are fixedly connected to the inner side of bracket 1, and buffer cylinder 12 is fixedly connected to the mounting bracket.

[0037] In this invention, when the steel plate is unloaded to the top of the support 1, it is first unloaded onto the buffer cylinder 12 by a crane. The piston rod of the buffer cylinder 12 retracts and slowly drops the steel plate onto the top of the roller 3 on the roller frame 2, thereby effectively reducing the impact of the steel plate on the overall material rack.

[0038] Please see Figure 2 Among them, the movable clamping plate 802 and the fixed clamping plate 803 are both fixedly connected to the opposite side of the buffer pad 13, and the opposite side of the two buffer pads 13 are provided with anti-slip texture.

[0039] In this invention, the buffer pad 13 fixedly connected to the movable clamping plate 802 and the fixed clamping plate 803 can increase friction, enhance the stability of clamping the steel plate, reduce wear, and extend the service life of the device.

[0040] Due to the unevenness of the steel plate and the varying thickness at the clamping positions, if the clamping mechanism 8 at each position uses the same clamping force, it may lead to over-clamping or insufficient clamping force in some areas, resulting in damage to the clamping mechanism 8 and affecting the feeding of the steel plate. To solve this problem, the present invention provides Embodiment Four:

[0041] Please see Figure 5 The top buffer pad 13 is hollow, and a pressure sensor 14 is fixedly connected to the inner bottom wall of the top buffer pad 13.

[0042] In this invention, the pressure sensor 14 can detect the pressure of the movable clamping plate 802 on the steel plate. By observing the pressure value, the worker can know the clamping force on the steel plate. The pressure sensor 14 can also be set with a threshold. After the pressure sensor 14 detects the required clamping force, it sends a signal to the control system. The control system will stop supplying air to the cylinder 801, thereby providing the required clamping force to the movable clamping plate 802, avoiding over-clamping or insufficient clamping force.

[0043] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
