A cutting device and a clamping device

Abstract

The present invention discloses a cutting device and a clamping device. The cutting device includes a cutting wheel and a clamping device. The clamping device includes a first clamping member and a second clamping member. The first surface of the first clamping member and the second surface of the second clamping member opposite to the first surface form a clamping surface. The cutting wheel is perpendicular to the clamping surface. The first surface and the second surface are both arc-shaped, and the curvatures of the first surface, the second surface and the cutting surface of the cutting wheel are the same. In the present invention, the clamping surface of the clamping device is arc-shaped, and the curvature of the clamping surface is the same as the curvature of the cutting surface of the cutting wheel. When the cutting wheel cuts the product clamped on the clamping surface, it contacts with multiple products at the same time and cuts them at the same time, which solves the problem that multiple products are ground by the cutting wheel due to different cutting times when cutting at the same time, thereby improving the cutting accuracy, cutting efficiency and life of the cutting wheel. At the same time, because the cutting wheel always contacts multiple products during cutting, the contact area is large, which also reduces the swing of the cutting wheel.

Description

Technical Field

[0001] The invention relates to the technical field of cutting tools, in particular to a cutting device and a clamping device. Background Art

[0002] The existing common cutting device has the following defects in its cutting process:

[0003] 1. Since the thickness of the cutting wheel is relatively thin, the grinding wheel will swing when rotating at high speed, causing deviation in the cutting size and instability;

[0004] 2. Since most cutting devices are plane-to-plane clamping devices, when the grinding wheel cuts multiple materials at the same time, the contact time with the cutting materials is different. The middle of the cutting wheel contacts the product first and leaves the product last. In this way, the middle part of the product will be cut for a long time. Although the product has been cut off, the two sides of the cutting wheel will still grind the two ends of the product, so that the middle size of the product will be different from the size on both sides, resulting in insufficient dimensional accuracy. The life of the cutting wheel and cutting efficiency are also affected. Summary of the invention

[0005] The main technical problem solved by the present invention is to provide a cutting device to solve the problem of insufficient cutting accuracy caused by the cutting wheel swinging when the cutting wheel cuts multiple products at the same time and the different contact time and cutting time with each product.

[0012] Wherein, the material storage area is a plurality of first grooves formed on the second surface along the direction of the cutting seam, and the plurality of first grooves are evenly arranged.

[0013] Wherein, the cutting device further comprises a feeding device, the feeding device comprises a pressing block and a base, and opposite sides of the material to be cut are respectively against the pressing block and the base;

[0014] The pressing block and the first clamping member are distributed along the same straight line, and the base and the second clamping member are distributed along the same straight line.

[0015] Wherein, the cross-section of the lower part of the pressing block and the cross-section of the upper part of the base are both arc-shaped, and have the same curvature as the cutting surface of the cutting wheel.

[0016] Wherein, a plurality of second grooves matching the diameter of the material to be cut are formed on the upper surface of the base, and the plurality of second grooves are evenly arranged.

[0021] The first surface and the second surface are both arc-shaped, and the first surface and the second surface have the same curvature.

[0022] The cutting device and the clamping device of the present invention have the following beneficial effects: the clamping surface of the clamping device is arc-shaped, and the curvature of the clamping surface is the same as the curvature of the cutting surface of the cutting wheel, so that when the cutting wheel cuts the product clamped on the clamping surface, it can contact with multiple products at the same time and complete the cutting at the same time, thus solving the problem of multiple products being ground by the cutting wheel due to different cutting times when being cut at the same time, thereby improving the cutting accuracy, cutting efficiency and the life of the cutting wheel; at the same time, since the cutting wheel always contacts multiple products during cutting, the contact area is large, which also reduces the swing of the cutting wheel.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

If the specific posture changes, the directional indication also changes accordingly. The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] Figures 1 to 4 A preferred embodiment of the cutting device of the present invention is shown, the cutting device includes a cutting wheel 1 and a clamping device 2, the clamping device 2 includes a first clamping member 22 and a second clamping member 23, a first surface 221 of the first clamping member 22 and a second surface 231 of the second clamping member 23 opposite to the first surface 221 form a clamping surface 21, and the cutting wheel 1 is perpendicular to the clamping surface 21; the first surface 221 and the second surface 231 are both arc-shaped, and the first surface 221, the second surface 231 and the cutting surface of the cutting wheel 1 have the same curvature, so that when cutting is performed, the cutting wheel 1 contacts with a plurality of materials 100 to be cut at different positions on the clamping surface 21 at the same time.

[0032] The arc surface clamping design enables the cutting device to contact multiple materials 100 to be cut at the same time when cutting multiple products. Firstly, it avoids the situation that when using a common flat clamp, the bottom of the cutting wheel 1 only contacts with one material 100 to be cut before cutting, thereby causing the cutting wheel 1 to have a large torque and unstable force swing. Secondly, when the cutting wheel 1 cuts multiple materials 100 to be cut at the same time, at least part of the materials 100 to be cut will be cut at the same time, reducing the situation that the materials 100 to be cut that are cut first are worn by both sides of the cutting wheel 1. The cutting device will be described in detail below.

[0033] like Figure 1 and Figure 2As shown, in this embodiment, the first clamping member 22 is located above the second clamping member 23, and the two clamp the material 100 to be cut together. The first surface 221 is the lower surface of the first clamping member 22, and the second surface 231 is the upper surface of the second clamping member 23. The clamping area of ​​the material 100 to be cut is between the two surfaces. The distribution of multiple materials 100 to be cut in the clamping area is affected by the shape of the clamping surface 21 and the shape of the material 100 to be cut. The cutting device of this embodiment cuts multiple products at the same time. In order to achieve the effect of simultaneous cutting, the shapes of the first surface 221 and the second surface 231 are set to be arc-shaped, and the curvature of the first surface 221 and the second surface 231 is set to be the same as the curvature of the cutting wheel 1, so that the arc surface of the first surface 221, the arc surface of the second surface 231 and the cutting surface of the cutting wheel 1 are matched. The material 100 to be cut is a round tube, so that the cutting wheel 1 can contact, cut and complete the cutting of multiple round tubes at the same time.

[0034] The cutting device in this embodiment also includes a base, the second clamping member 23 is fixed on the base, and a material storage area 232 is provided on the second surface 231. The second clamping member 23 is provided with a second assembly groove 233 at the bottom, which is installed on the base and cannot be moved. The material storage area 232 is opened on the second surface 231 at the top, and the material 100 to be cut is clamped in the material storage area 232 during cutting. The material storage area 232 can be the space between the first surface 221 and the second surface 231, or it can be an additional accommodation space provided on the second surface 231. In this embodiment, the material storage area 232 is a plurality of first grooves formed on the second surface 231 along the vertical direction of the cutting seam 200, and the plurality of first grooves are evenly arranged, and the first grooves are used to accommodate the material to be cut.

[0035] The cross-sectional shape of the clamping surface 21 in this embodiment is the same as the curvature of the cutting surface of the cutting wheel 1. The cutting wheel 1 is circular, and the cutting surface of the cutting wheel 1 is a part of the arc of the outer surface of the cutting wheel 1. Assuming that the material 100 to be cut is a round tube, when the cutting wheel 1 cuts the material 100 to be cut clamped on the clamping surface 21, the upper surface arc formed by connecting points on the upper surface of multiple materials 100 to be cut and the lower surface arc formed by connecting points on the lower surface coincide with the cutting surface of the cutting wheel 1. The cutting wheel 1 contacts all the materials 100 to be cut placed on the clamping surface 21 at the same time, and the cutting is completed at the same time, avoiding the defects of different cutting times of multiple materials 100 to be cut, resulting in the materials 100 to be cut that are cut first being ground by the cutting wheel 1, and the lengths of the materials 100 to be cut are different, thereby improving the cutting accuracy and consistency.

[0036] like Figure 3As shown, in this embodiment, the clamping device 2 is provided with a cutting slit 200 that passes through the first clamping member 22 and the material storage area 232, and the cutting wheel 1 passes through the cutting slit 200 to cut the material 100 to be cut in the material storage area 232. The cutting method in the present invention is to cut multiple materials 100 to be cut at the same time, and the cutting wheel 1 moves vertically downward through the first clamping member 22 to reach the upper surface of the second clamping member 23, and abuts against the material 100 to be cut in the material storage area 232, and continues to move downward to cut the material, and the cutting slit 200 located on the first clamping member 22 facilitates the clarification of the positional relationship between the cutting wheel 1 and the pre-cutting position of the material 100 to be cut, and can also avoid the swing of the cutting wheel 1 to a certain extent.

[0037] The first clamping member 22 may be provided with a through slot, or the first clamping member 22 may be provided with a first cutting clip 222 and a second cutting clip 223 disposed adjacent to each other, and the through slot or the gap between the first cutting clip 222 and the second cutting clip 223 forms the upper part of the cutting slit 200. The second clamping member 23 may also be provided with a through slot, or the second clamping member 23 may be provided with two first mounting clips 234 and a second mounting clip 235 disposed opposite to each other, and the gap between the first mounting clip 234 and the second mounting clip 235 forms the lower part of the cutting slit 200. The second method is adopted in the present embodiment, and the size of the cutting slit 200 can be adjusted by adjusting the distance between the first cutting clip 222 and the second cutting clip 223, and the first mounting clip 234 and the second mounting clip 235.

[0038] The cutting device in this embodiment also includes a feeding device 3, which includes a pressing block 31 and a base 32. The opposite sides of the material 100 to be cut are respectively against the pressing block 31 and the base 32, which are used to clamp the material 100 to be cut and transfer it to the cutting device. The pressing block 31 and the first clamping member 22 are distributed along the same straight line, and the base 32 and the second clamping member 23 are distributed along the same straight line. The base 32 is used to carry the material 100 to be cut, and the pressing block 31 is used to press the material 100 to be cut, so that the material 100 to be cut is clamped between the pressing block 31 and the base 32. The feeding device 3 is arranged in front of the cutting device to clamp the material 100 to be cut before cutting, and forms a cutting assembly line with the cutting device.

[0039] The cross-section of the lower part of the pressing block 31 and the cross-section of the upper part of the base 32 in this embodiment are both arc-shaped and have the same curvature as the cutting surface of the cutting wheel 1. The clamping design of the feeding device 3 is the same as the setting of the clamping device 2, so that the material 100 to be cut is arranged according to the preset shape during cutting before entering the clamping device 2, and there is no need to adjust the position later.

[0040] In this embodiment, the upper surface of the base 32 is formed with a plurality of second grooves 321 that match the diameter of the material 100 to be cut, and the plurality of second grooves 321 are evenly arranged. The first grooves correspond to the second grooves 321 one by one, and the widths of the first grooves and the second grooves 321 both match the diameter of the material 100 to be cut, and the depths of the first grooves and the second grooves 321 both are greater than the diameter of the material 100 to be cut.

[0041] like Figure 2 and Figure 4 As shown, the width of the first groove matches the diameter of the material 100 to be cut, so that the material 100 to be cut does not produce too much lateral displacement when placed in the first groove. Of course, when cutting different materials 100 to be cut, the first groove can be set to different diameters to adapt to the size of the material 100 to be cut. Multiple first grooves are arranged adjacent to each other, and the radius of the arc formed by the lowest points of the multiple first grooves is also the same as the radius of the cutting wheel 1. The depth of the first groove can be freely set. For example, when it is set to 1.5 times the diameter of the material 100 to be cut, each first groove can vertically accommodate two materials 100 to be cut, and a part of the material 100 to be cut located at the upper part protrudes from the first groove and abuts against the cutting wheel 1.

[0042] The diameter, shape, depth and setting method of the second groove 321 are the same as those of the first groove. The base 32 and the second clamping member 23 are located on the same straight line, so that the first groove is connected to the rear of the second groove 321. The material 100 to be cut is transmitted to the clamping device 2 through the feeding device 3 for cutting.

[0043] The cutting device in this embodiment also includes a driving device for driving the first cutting clamp 222, the second cutting clamp 223 and the pressing block 31 to move. Preferably, the driving device is a cylinder. The first cutting clamp 222, the second cutting clamp 223 and the pressing block 31 are all driven by the cylinder to move, pressing or moving away from the corresponding second clamp 23 or base 32. The first cutting clamp 222, the second cutting clamp 223 and the pressing block 31 are all controlled by a program, and are moved away from the second clamp 23 or base 32 to discharge the material before processing, and move downward to press the material 100 to be cut for cutting after the discharge is completed. The first cutting clamp 222 and the second cutting clamp 223 can also move relative to each other to adjust the size of the cutting seam 200.

[0044] In order to solve the technical problem, the present invention also provides a clamping device, the clamping device includes a first clamping member and a second clamping member, and the first surface of the first clamping member and the second surface of the second clamping member opposite to the first surface form a clamping surface. The shapes of the first surface and the second surface are both arc-shaped, and the curvatures of the first surface and the second surface are the same. The clamping device of the present application is the same as the clamping device in the above-mentioned cutting device, which has been described in detail in the cutting device and will not be repeated here.

[0045] When using the cutting device and the clamping device of the present invention, the clamping surface of the clamping device is arc-shaped, and the curvature of the clamping surface is the same as the curvature of the cutting surface of the cutting wheel, so that when the cutting wheel cuts the product clamped on the clamping surface, it can contact with multiple products at the same time and cut them at the same time, which solves the problem of multiple products being ground by the cutting wheel due to different cutting times when they are cut at the same time, thereby improving the cutting accuracy, cutting efficiency and the life of the cutting wheel; at the same time, because the cutting wheel always contacts multiple products during cutting, the contact area is large, which also reduces the swing of the cutting wheel.

[0046] The above description is only an implementation mode of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
