Description

Technical Field

[0001] The utility model relates to the technical field of numerical control sawing machines, in particular to an automatic feeding mechanism for a numerical control sawing machine. Background Art

[0002] Band sawing machines are divided into two types: vertical and horizontal, and are basically used for cutting materials such as bar materials. During the cutting process, after each section of material is cut, it is necessary to push the material section forward to the cutting position for the next cutting. At present, the feeding method is basically manual feeding. In this way, the labor intensity of the operator is very high, and when pushing the material section, it cannot be accurately pushed to the correct position, and manual feeding is also prone to dangerous accidents. For bar materials with a relatively large diameter, manual feeding is more difficult.

[0003] The existing automatic feeding mechanism of a numerical control sawing machine transports workpieces through feeding rollers, driving the workpieces to move forward. After the feeding is completed, the fixture on the workbench of the band sawing machine clamps the workpiece, then the clamping device is turned on, and the cylinder drives the clamping device to move back to its original position.

[0004] However, the feeding rollers do not limit the position of the workpiece during transportation, which results in the position of the workpiece being easily offset during transportation, thus requiring manual support, increasing the workload of the staff, and being very inconvenient to use. Therefore, we propose an automatic feeding mechanism for a numerical control sawing machine. Summary of the Utility Model

[0005] Aiming at the above-mentioned shortcomings of the existing technology, the utility model provides an automatic feeding mechanism for a numerical control sawing machine, which can effectively solve the problem that the existing technology does not limit the position of the workpiece, resulting in the position of the workpiece being easily offset during transportation, thus requiring manual support, increasing the workload of the staff, and being very inconvenient to use.

A plurality of third grooves are formed on the outer side of one of the connecting rods. The clamping block is clamped with the third groove. A fixing rod is fixedly connected to the top of the clamping block and located inside the spring. One end of the fixing rod is fixedly connected to a pull ring above the third slider.

[0023] The present utility model will be further described below with reference to the embodiments.

[0024] Embodiment: Refer to Figures 1 to 5 , an automatic feeding mechanism for a numerical control sawing machine, comprising a sawing machine body 1, a sawing machine assembly 3 fixedly connected to the top of the sawing machine body 1, a fixing plate 8 fixedly connected to one side of the sawing machine body 1, four conveying roller mechanisms 7 arranged inside the fixing plate 8, a limiting mechanism arranged inside the conveying roller mechanism 7, a moving mechanism arranged on the top of the sawing machine body 1 and on one side of the sawing machine assembly 3, and a fixing mechanism arranged on the top of the moving mechanism.

[0025] The conveying roller mechanism 7 comprises two discs 21 arranged inside the fixing plate 8, a plurality of connecting rods 24 fixedly connected to the side of the two discs 21 close to each other, a rotating shaft 11 fixedly connected to the side of the two discs 21 away from each other, the rotating shaft 11 being rotatably connected inside the fixing plate 8, and four gears 15 fixedly connected to the outer sides of four of the rotating shafts 11 and located on one side of the fixing plate 8, a toothed belt 16 meshing with the outer sides of the four gears 15, and a first motor 12 fixedly connected to one side of the fixing plate 8, the output end of the first motor 12 being fixedly connected to one of the rotating shafts 11, which is beneficial to transporting workpieces, has higher practicability compared with traditional conveying rollers, and is convenient for installing auxiliary tools.

[0026] The limiting mechanism comprises four third sliders 25 slidably connected to both ends of two relatively opposite connecting rods 24, a limiting disc 23 fixedly connected to the outer sides of every two third sliders 25, a fourth groove 32 opened inside four of the connecting rods 24, a spring 27 arranged at one end of the fourth groove 32, a clamping block 30 fixedly connected to one end of the spring 27, a plurality of third grooves 22 opened on the outer side of one of the connecting rods 24, the clamping block 30 being clamped with the third grooves 22, a fixing rod 33 fixedly connected to the top of the clamping block 30 and inside the spring 27, and a pull ring 26 fixedly connected to one end of the fixing rod 33 and located above the third slider 25. The position of the workpiece is restricted by the two limiting discs 23, avoiding the problem that the traditional conveying roller needs manual support when the conveying position deviates. Then, pulling the pull ring 26 can drive the clamping block 30 to leave the inside of the third groove 22 through the fixing rod 33, and the distance between the limiting discs 23 can be adjusted, so as to be applicable to workpieces of different sizes.

[0027] The moving mechanism includes a first groove 13 opened at the top of the sawing machine body 1. Inside the sawing machine body 1 and on one side of the first groove 13, a second groove 18 is opened. A lead screw 19 is rotatably connected inside the second groove 18.

[0030] The working principle of the present utility model is as follows: By starting the first motor 12 through the control panel 2, the rotating shaft 11 can be driven to rotate. The rotating rotating shaft 11 drives the disc 21 and the connecting rod 24 to rotate, and drives the gear 15 to rotate through the meshing transmission of the toothed belt 16, driving the other conveying roller mechanisms 7 to rotate. Then, the workpiece can be placed above the conveying roller mechanisms 7 to drive the workpiece to move forward. The workpiece is limited by the limit disc 23. By starting the electric push rods 4 through the control panel 2, the clamping blocks 5 can be driven to clamp the workpiece, and then the sawing machine can be started to operate on the workpiece. When encountering a large workpiece, by pulling the pull ring 26, the clamping block 30 can be driven to leave the inside of the third groove 22 through the fixing rod 33. By sliding the third slider 25 on the outside of the connecting rod 24, the distance between the limit discs 23 can be adjusted. By starting the second motor 14 through the control panel 2, the lead screw 19 can be driven to rotate, thereby driving the first slider 17 to slide inside the second groove 18, and driving the second slider 20 and the fixing mechanism on the top to move.
