Description

Technical Field

[0001] The utility model relates to the technical field of cutting machine positioning, in particular to a four-column guiding positioning mechanism. Background Art

[0002] Cutting machines are indispensable equipment for some light industries. According to traditional concepts, cutting machines are machines that use the force of machine movement to pressurize the knife die to punch non-metallic materials. Modern cutting machines have undergone some changes, and advanced technologies such as high-pressure water jets and ultrasound have begun to be used in leather punching technology. However, people still classify these devices as cutting machines. The existing cutting machines are not accurately positioned during positioning and cutting, resulting in poor cutting effects; therefore, they do not meet existing needs. In this regard, we propose a positioning and cutting mechanism for cutting machines.

[0003] For example, a special positioning device for a cord cutting machine with application number CN202022980952.8 comprises a machine body, a table top is arranged on the top of the machine body, symmetrically distributed hydraulic cylinders are arranged on the top of the table top, and the piston rods of the hydraulic cylinders are connected to a top frame, a protective plate is arranged on the top of the table top on the inner side of the two hydraulic cylinders, a guard frame is fixed on the table top by bolts, and a positioning mechanism is arranged on the guard frame and the table top; the beneficial effects of the utility model are as follows: through the designed positioning mechanism, the combination of the positioning block and the positioning groove is utilized to increase the positioning of the guard frame and the table top installation, so that the guard frame and the table top are fixed more quickly, and the efficiency of fixing the guard frame and the table top is improved; through the designed guide mechanism, the guide of the connection between the guard plate and the table top is increased, so that the guard plate and the table top are fixed more quickly, and the efficiency of fixing the guard plate and the table top is improved; through the designed positioning component, it helps to support the connecting column and increase the positioning effect of the connecting column. However, the four-column guide positioning mechanism cannot be adjusted and can only fix the cut objects of fixed size, so the application scope is small. At the same time, when the cutting knife cuts the cut object, the cutting knife has a poor cutting effect on the cut object under the impact of vibration and cutting pressure, and the fixing parts of the cutting knife will be affected, causing the parts to loosen. Therefore, in view of this, the existing structural deficiencies are studied and improved, and a four-column guide positioning mechanism is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a four-column guiding and positioning mechanism to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a four-column guiding and positioning mechanism, comprising a support column and a groove, wherein the interior of the support column is provided with a groove, and an electric push plate is slidably connected to the interior of the groove, and a fixing mechanism is fixedly connected to one side of the electric push plate, and a shock absorbing mechanism is arranged at the upper end of the support column.

[0006] Preferably, the fixing mechanism includes a fixing block fixedly connected to one side of the electric push plate, and the upper layer of the fixing block is fixedly connected to an electric cylinder, the top of the electric cylinder is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to an electric push rod, and a pressing suction cup is provided on one side of the electric push rod.

[0007] Preferably, the top of the electric push plate is fixedly connected to a lifting rod, and the top of the lifting rod is fixedly connected to a conveying frame.

[0008] Preferably, a conveying rod is provided inside the conveying frame, and a conveying block is movably connected to the outside of the conveying rod.

[0009] Preferably, a fixing plate is fixedly connected to one side of the conveying block, and a pressing rod is fixedly connected to the bottom of the fixing plate.

[0010] Preferably, a shock absorbing mechanism is provided at the bottom of the pressing rod, and a quick release plate is provided on one side of the shock absorbing mechanism, and a cutting tool is movably connected to one side of the quick release plate.

[0011] Preferably, the shock absorbing mechanism internally includes a top plate fixedly connected to the bottom position of the pressing rod, and the bottom of the top plate is fixedly connected to a shock absorber, the bottom of the top plate is fixedly connected to a shock absorbing block, and the bottom of the shock absorbing block is provided with a bottom plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can fix the cut object by setting the fixing mechanism and the shock absorbing mechanism. When the cut object is placed on the upper end of the conveyor belt, when the conveyor belt drives the cut object to the lower end of the cutting knife, the pressing suction cup inside the fixing mechanism can fix the cut object, and the electric cylinder inside the fixing mechanism can be adjusted according to the thickness of the cut object, and the electric push rod can adjust the length of the push rod according to the size of the cut object, thereby improving the fixing effect of the cut object and increasing the adaptation range of the fixing mechanism. The positioning mechanism inside the traditional cutting machine cannot be adjusted and can only fix the cut object of a fixed size, and the application range is small. At the same time, when the cutting knife cuts the cut object, the cutting knife is impacted by vibration and cutting pressure, and the cutting effect of the cut object is poor, and the fixing parts of the cutting knife will be affected, resulting in loose parts. The shock absorbing mechanism added by the utility model, the shock absorber and the shock absorbing block cooperate with each other to reduce the vibration amplitude during cutting to the greatest extent, so that the cutting tool is more stable during cutting, and the loosening of the tool parts is avoided, which affects the service life of the device.

[0014] 2. The utility model is provided with a pressing rod and a quick-release plate. When the cutting tool cuts the object to be cut, the pressing rod applies pressure to the cutting tool to increase the cutting speed of the object to be cut. At the same time, the pressing rod can control the cutting frequency of the cutting tool so that the object to be cut can be cut evenly. The quick-release plate is used to facilitate the replacement of cutting tools of different lengths. When the tool is severely worn, the cutting tool can be quickly replaced to keep the cutting tool sharp and ensure the cutting speed of the cutting tool. BRIEF DESCRIPTION OF THE DRAWINGS
