Description

Technical Field

[0001] The present invention mainly relates to the technical field of mechanical cutting, and in particular to a raw material cutting device for mechanical processing. Background Art

[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. In a mechanical factory, before machining a part, the part is usually cut mechanically. For example, a cylindrical or directional workpiece is placed on a cutting machine for cutting, and then a subsequent cutting process is performed to process it into the required parts, such as nuts, gaskets, etc.

[0003] In order to understand the cutting equipment in the prior art, after searching, the Chinese patent with the announcement number: CN 215392794 U discloses a raw material cutting equipment for mechanical processing, including a workbench, a bracket is provided at the upper end of the workbench, the bottom end of the bracket is set in an L shape, a fastening bolt 1 is installed at the bottom end of the bracket, and the workbench is provided with a sliding hole 2 corresponding to the fastening bolt 1, and the four corners of the bottom end of the workbench are fixedly connected to the support legs, a turntable is provided above both sides of the workbench, an annular groove is provided on the outer edge of the turntable, and the bottom end of the turntable is fixedly connected to the support column, and the workbench is provided with a sliding hole 1 corresponding to the support column, and the support column is fixedly connected to the slider at the top of the workbench, and the other end of the slider is slidably connected to the card slot, and the card slot is set in an L shape;

DETAILED DESCRIPTION

[0035] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] For examples, please refer to the attached Figure 1-6 A raw material cutting device for mechanical processing includes a base frame 1, a fixed cover 7, a lifting member, and a clamping member.

[0039] In the present application, a cutting table 12 and a fixing frame 2 are fixedly installed on a base frame 1. The base frame 1 is a rectangular workpiece, which is used to support and install the parts in the present application. The base frame 1 can also be fixedly installed on related equipment to support and install the equipment, and the fixing frame 2 is used to install subsequent cutting blades 8 and other components, and plays a supporting and installing role. The fixing frame 2 is located on one side of the cutting table 12 for easy operation. At the same time, a cutting groove 13 is provided on the cutting table 12 for accommodating the cutting blade 8.

[0040] To further explain, the fixed cover 7 is arranged on one side of the fixed frame 2, and a cutting blade 8 for cutting the workpiece is provided in the fixed cover 7, so the fixed cover 7 is used to install the cutting blade 8, and the cutting blade 8 is a serrated blade, which is circular and is used to cut the workpiece, and a third motor 24 for driving the cutting blade 8 to rotate is fixedly installed on the outside of the fixed cover 7, and the third motor 24 is used to drive the cutting blade 8 to rotate to realize the cutting function.

[0041] It should be noted that in the present application, the lifting member is disposed on the fixing frame 2 to drive the fixing cover 7 to slide, thereby controlling the height of the cutting blade 8;

[0042] The details are as follows:

[0043] The lifting member includes a guide frame 4 fixedly connected to the outside of the fixing frame 2, a first threaded rod 5 rotatably installed in the guide frame 4, and a first motor 3 fixedly connected to the guide frame 4, a driving shaft of the first motor 3 is fixedly connected to the threaded rod, a nut block is threadedly installed on the threaded rod, and a connecting frame 6 is fixedly connected to the outside of the nut block, and the connecting frame 6 is fixedly connected to the fixing cover 7;

[0044] Then they are introduced one by one. The guide frame 4 is used to install the threaded rod. At the same time, it guides the nut block on the threaded rod, and then realizes the linear lifting and lowering of the nut block, so it plays a guiding role to facilitate the movement of the nut block. Then the first motor 3 is used to drive the threaded rod to rotate as a power source, and the connecting frame 6 is fixedly connected to the fixed cover 7 by bolts, playing the role of a bridge, which can drive the fixed cover 7 to adjust the height through the lifting member.

[0045] Furthermore,

[0046] The clamping member is arranged on the top surface of the cutting table 12 to clamp the workpiece;

[0047] It should be noted that the clamping member can also switch between two states: clamping a workpiece with a rectangular structure and clamping a workpiece with a cylindrical structure.

[0048] Because it is found that in the prior art, it is not possible to switch between clamping a rectangular workpiece and a cylindrical workpiece;

[0049] Because in the actual processing of mechanical factories or schools of mechanical majors, there are more cylindrical and rectangular workpieces, and generally the second type of workpieces are clamped and fixed;

[0050] How to achieve this is described as follows:

[0051] The clamping member includes a plurality of clamping frames 15 slidably arranged on the cutting table 12, an adjusting plate 18 rotatably installed on the upper and lower sides of the clamping frame 15, a rotating rod 19 rotatably arranged outside the clamping frame 15, a plurality of bevel teeth 20 fixedly connected to the outside of the rotating rod 19, a non-return pawl 21 rotatably installed outside the clamping frame 15, a notch 17 arranged on the cutting table 12, a second threaded rod 16 rotatably installed in the notch 17, and a second motor 14 fixedly connected to the outside of the cutting table 12;

[0052] The detailed introduction is as follows:

[0053] The second motor 14 is fixedly connected to the second threaded rod 16. The second motor 14 serves as a power source for the second threaded rod 16 and is used to drive the second threaded rod 16 to rotate. Two nuts are threadedly installed on the second threaded rod 16, and the rotation of the second threaded rod 16 can realize the work of the nuts. Under the guidance of the notch 17, the two relative clamping frames 15 can slide toward each other or first back to back, which is convenient for control. In this application, the nuts are blocked by other parts, so there are no numbers, and the two nuts are fixedly connected to the corresponding clamping frames 15 respectively, so the sliding of the nuts can drive the clamping frames 15 to slide, thereby controlling the clamping frames 15 to clamp the workpiece.

[0054] Special instructions are as follows:

[0055] In the present application, the rotating rod 19 is fixedly connected to the adjusting plate 18. Obviously, the adjusting plate 18 is rotatably mounted in the clamping frame 15, and the rotating plate is convenient for manual rotation, so as to control the position of the adjusting plate 18;

[0056] The non-return pawl 21 is rotatably connected to the clamping frame 15 via a rotating shaft 22. A torsion spring is sleeved on the rotating shaft 22. Under the torsion force of the torsion spring, the non-return pawl 21 can be tightly engaged with the helical teeth 20 (equivalent to a ratchet mechanism). The two ends of the torsion spring are fixedly connected or engaged with the clamping frame 15 and the non-return pawl 21 respectively.

[0057] refer to Figure 3-4It can be seen that when the non-return ratchet is engaged with the bevel teeth 20, the adjustment plate 18 can only be rotated outward. The purpose of such a setting is that when the clamping frame 15 clamps the workpiece, under the action of clamping, since the action of force is mutual, the workpiece will push the adjustment plate 18 to rotate into the clamping frame 15, and at this time, under the cooperation of the non-return ratchet and the bevel teeth 20, the adjustment plate 18 cannot rotate into the clamping frame 15, and then the two clamping frames 15 slide toward each other, so that the workpiece can be tightened and clamped by the adjustment plate 18.

[0058] It can be seen that in the present application, four clamping frames 15 are provided, two in a group, and are respectively arranged at both ends of the cutting table 12 for clamping the workpiece.

[0059] In order to facilitate the rotation of the adjustment plate 18, a lever 23 is fixedly connected to the non-return pawl 21 for manual operation by the staff.

[0060] In order to ensure stable sliding of the clamping frame 15, a slide groove 25 is provided at the position of the clamping frame 15 corresponding to the cutting table 12. A slider is slidably installed in the slide groove 25. The slider is fixedly connected to the clamping frame 15 and is used to clamp and fix the workpiece when the clamping frame 15 slides.

[0061] Please refer to the following operations for details:

[0062] Case 1: the workpiece to be cut is a cuboid;

[0063] Place the workpiece on the cutting table 12, then start the second motor 14 to drive the second threaded rod 16 to rotate, and then under the guidance of the notch 17, the nuts drive the corresponding two clamping frames to slide towards each other, so that the workpiece is clamped and fixed by the vertical adjustment plate 18;

[0064] Then, the first motor 3 and the third motor 24 are started to work, and the first motor 3 drives the first threaded rod 5 to rotate, so that the fixed cover 7 moves downward, and at the same time, the third motor 24 drives the cutting blade 8 to rotate, and then the cutting blade 8 cuts the workpiece;

[0065] Case 2: the workpiece is cylindrical;

[0066] First, the lever 23 is moved to drive the non-return pawl 21 to rotate, so that the non-return pawl 21 is not engaged with the helical teeth 20, and then the adjustment plate 18 is rotated into the clamping frame 15, so that the adjustment plate 18 is tilted in the clamping frame 15, and the tilt angle can be adjusted according to the diameter of the cylindrical workpiece, refer to Figure 6 ;

[0067] Then release the lever 23, and under the torsion force of the torsion spring, the non-return pawl 21 meshes with the helical teeth 20 again. Figure 4, (the principle of ratchet structure), so under the action of the non-return pawl 21 and the bevel teeth 20, the adjustment plate 18 cannot rotate into the clamping frame 15, which is an ambush for the clamping of the workpiece later; the adjustment plate 18 can only be rotated outward;

[0068] After the adjustment is completed, the adjustment plates 18 in the clamping frames 15 are all tilted, and then the cylindrical workpiece is placed on the cutting table 12 and then located between the two clamping frames 15;

[0069] The same principle applies. The second motor 14 is started again. The cylindrical workpiece can be clamped by the multiple adjustment plates 18 in multiple directions. Figure 6 , it can be found that the eight adjustment plates 18 in the present application respectively interfere with the cylindrical workpiece, so that the clamping effect is better;

[0070] Then the workpiece can be cut by the cutting blade 8.

[0071] For details, please refer to the attached Figure 1 A rotating column is rotatably installed on one side of the outside of the fixed cover 7, and a connecting plate 10 is fixedly connected to the rotating column. A protective cover 9 is fixedly connected to the outside of the connecting plate 10. The protective cover 9 is sleeved on the outside of the fixed cover 7, and a positioning bolt 11 is penetrated and threadedly installed on the outside of the connecting plate 10.

[0072] The purpose of such arrangement is that before the cutting blade 8 is processed and cut, the protective cover 9 can be rotated clockwise to allow the protective cover 9 to shield and protect the position of the cutting blade 8 to prevent debris from flying out during the cutting process. At the same time, after rotation, the positioning bolt 11 can also be rotated to contact the fixing cover 7 to fix the protective cover 9.

[0073] For details, please refer to the attached Figure 1 The lifting member is a hydraulic cylinder, which is fixedly mounted on a fixed frame 2 , and a piston rod of the hydraulic cylinder is fixedly connected to a fixed cover 7 .

[0074] Specifically, the lifting and lowering of the fixed cover 7 can also be controlled by a hydraulic cylinder.

[0075] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0076] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
