[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0024] like Figures 1 to 4 As shown, this utility model proposes a cutting device for cutting a cylindrical shell 10. The cutting device includes a base 1, a fixing component 2, and a cutting component 3. The base 1 is used to place the shell 10; the fixing component 2 is installed on the base 1 and includes at least one pair of clamping members for clamping the shell 10; and the cutting component 3 is installed on the base 1 and positioned above the fixing component 2, and is used to cut the shell 10 clamped by the fixing component 2. The base 1 provides stable support for the housing 10. The fixing component 2 can stably fix the cylindrical housing 10 on the base 1, preventing the cylindrical housing 10 from shaking or shifting on the base 1. The cutting component 3, which is set above the fixing component 2, can cut the fixed housing 10, effectively improving the cutting accuracy of the cylindrical housing 10. After the cylindrical housing 10 is placed on the base 1 of the cutting device, the clamping component of the fixing component 2 stably clamps the housing 10, fixing the position of the housing 10 and preventing the cylindrical housing 10 from shaking or shifting during the cutting process. The cutting component 3 cuts the cylindrical housing 10, improving the cutting accuracy of the cylindrical housing 10.
[0025] See Figure 1To reduce the weight of the cutting device and improve its portability, the base 1 is provided with multiple weight-reducing holes 13. Optionally, the weight-reducing holes 13 are elongated holes formed in the base 1 along the radial direction of the housing 10 (as shown in the second direction in the figure). This arrangement does not affect the end face contact between the housing 10 and the base 1, ensuring that the housing 10 is stably placed on the base 1.
[0026] See Figure 2 and Figure 4 Each pair of clamping members includes a first clamping member 21 and a second clamping member 22 disposed opposite to each other. The first clamping member 21 and the second clamping member 22 are used to clamp the housing 10 radially (e.g., Figure 1 (Second direction) on both sides. The relative arrangement of the first clamping member 21 and the second clamping member 22 not only enhances the stability of the housing 10 clamping, but also ensures that the housing 10 is subjected to uniform force during clamping, preventing displacement of the housing 10 during cutting. With the cooperation of the first clamping member 21 and the second clamping member 22 clamping the radial sides of the housing 10 and the base 1 supporting the bottom of the housing 10, force is applied to the housing 10 from three angles, fixing the housing 10 to the base 1, ensuring the stability of the housing 10, and thus improving the cutting accuracy of the housing 10.
[0027] The fixing component 2 may include multiple pairs of clamping members, which can be positioned along the axial direction of the housing 10 (e.g., ...). Figure 1 The clamping elements are spaced apart along the axial direction of the housing 10. This provides multiple clamping positions for the housing 10 in the axial direction, thereby further improving the stability of the housing 10 and preventing it from shifting due to the cutting force. It also allows the cutting device to cut multiple housings or different parts of the housing 10 without having to disassemble and reassemble the housing 10 multiple times, thus ensuring the cutting accuracy of the housing 10 and improving the cutting efficiency.
[0028] According to an embodiment of the present invention, the first clamping member 21 includes a first column 211 and a clamping part 212. The first column 211 is mounted on the base 1; the clamping part 212 is movably disposed on the first column 211 and can be clamped along the height direction of the first column 211 (e.g., ...). Figure 1 The clamping part 212 is configured to fit against the outer side wall of the housing 10. The first column 211 connects the base 1 and the clamping part 212, and can stably fix the clamping part 212 on the base 1. The movement of the clamping part 212 along the height direction of the first column 211 allows the fixing assembly 2 to clamp housings 10 of different sizes. According to the different sizes of housings 10, the position of the clamping part 212 along the height direction of the first column 211 is adjusted to meet the clamping requirements of housings 10 of different sizes and to stably clamp the housing 10.
[0029] Among them, the first direction, the second direction, and the third direction are perpendicular to each other.
[0030] In one embodiment, a threaded rod is provided on the side of the clamping part 212 near the first column 211. The first column 211 has an elongated hole along its height direction, through which the threaded rod passes and is threadedly connected to a nut. The width of the elongated hole along the axial direction of the housing 10 is greater than or equal to the outer diameter of the threaded rod, and the width of the elongated hole along the axial direction of the housing 10 is less than the outer diameter of the nut. This ensures that the threaded rod passes through the elongated hole, and the nut can fix the threaded rod to the first column 211. The threaded rod is passed through the elongated hole, and the clamping part 212 is moved and adjusted along the height direction (i.e., the first direction) of the first column 211. When the clamping part 212 moves to a suitable position that fits against the outer wall of the housing 10, the nut is threadedly connected to the threaded rod, thereby fixing the clamping part 212 to the first column 211.
[0031] As an alternative embodiment, the first column 211 is provided with a slide rail along the height direction, and the clamping part 212 is provided with a slider that matches the slide rail on the side near the first column 211. The slider and the slide rail are slidably engaged. When the clamping part 212 moves to a suitable position that fits against the outer wall of the housing 10, the slider is fixed to the slide rail by a locking mechanism, thereby fixing the clamping part 212 to the first column 211.
[0032] Furthermore, the first column 211 is detachably mounted on the base 1.
[0033] See Figure 1 and Figure 2 The clamping part 212 includes a connecting plate 2121 and two claws 2122. The connecting plate 2121 is movably disposed on the first column 211 and can move along the height direction of the first column 211. The two claws 2122 are disposed opposite to each other at both ends of the connecting plate 2121 along the height direction of the first column 211. The opposite side of the two claws 2122 is set as a symmetrical inclined surface for fitting against the outer wall of the housing 10. The connecting plate 2121 moves and adjusts along the height direction of the first column 211 according to the height and size of the housing 10, so that the clamping part 212 can clamp housings 10 of different sizes and heights, improving the versatility and clamping strength of the clamping part 212; the relative arrangement of the two jaws 2122 can apply a uniform clamping force to the housing 10, increasing the stability and strength of the clamping part 212; the opposite side of the two jaws 2122 is set as a symmetrical inclined surface, increasing the contact area between the jaws 2122 and the housing 10, increasing friction, and improving the clamping effect; the movement of the connecting plate 2121 along the height direction of the first column 211 and the design of the symmetrical inclined surfaces of the two jaws 2122 enable the clamping part 212 to clamp housings 10 of different heights and sizes, improving the versatility of the cutting device.
[0034] Furthermore, both jaws 2122 are detachably mounted on the connecting plate 2121. When the jaws 2122 are damaged, they can be simply removed from the connecting plate 2121 and replaced, which can reduce the maintenance cost of the cutting device and extend its service life.
[0035] Furthermore, to improve the versatility of the clamping part 212 in clamping housings 10 of different sizes, shapes, and materials, along the height direction of the first column 211 (e.g., Figure 1 In the first direction), the relative position between the two claws 2122 is adjustable. As one embodiment, the claw 2122 is provided with a threaded hole on the side near the first column 211, and the connecting plate 2121 is provided with multiple countersunk holes along the height direction of the first column 211. The bolt passes through the countersunk holes of the connecting plate 2121 and is threadedly connected to the threaded hole of the claw 2122.
[0036] In order to adaptably clamp housings 10 of different sizes, the second clamping member 22 is positioned radially along the housing 10 (i.e., Figure 1 The second direction is adjustable. Optionally, the base 1 has multiple through holes along the radial direction of the housing 10, and the fixing member passes through the second clamping member 22 and the through holes to fix the second clamping member 22 to the base 1. Further, the fixing member can be a bolt and a nut, with the bolt passing through the through holes on the second clamping member 22 and the base 1 and threadedly connected to the nut.
[0037] See Figure 1 and Figure 2 The second clamping member 22 includes a second column 221 and a clamping member 222. The second column 221 is mounted on the base 1, and the clamping member 222 is mounted on the second column 221. The clamping member 222 is configured to be radially movable relative to the second column 221 along the housing 10. The radial movement of the clamping member relative to the second column 221 along the housing 10 allows the clamping member to be adjusted in position according to the size of the housing 10, so as to achieve clamping with the outer wall of the housing 10 of different sizes, thereby expanding the size range of the housing 10 that the fixing assembly 2 can clamp.
[0038] As one embodiment, the clamping member 222 can be a bolt, and the second column 221 is provided with a threaded hole that is threaded to the bolt. The threaded engagement between the bolt and the threaded hole enables the bolt to move radially relative to the second column 221 along the housing 10.
[0039] Furthermore, the second clamping member 22 also includes a flange nut 223, which is detachably mounted on the second column 221, and a bolt can be threadedly connected to the flange nut 223.
[0040] To facilitate quick and easy replacement of the flange nut 223, the flange nut 223 is detachably installed on the second column 221.
[0041] Furthermore, the cutting component 3 is configured to be along the height direction (i.e. Figure 1 The position (first direction) is adjustable. The height of the cutting assembly 3 can be adjusted according to the height and size of the housing 10, enabling the cutting assembly 3 to cut housings 10 of different sizes and improving the versatility of the cutting device.
[0042] See Figures 1 to 3 The cutting device also includes two support columns 4, two first sliders 5, and a guide rail 6. The two support columns 4 are installed parallel to each other and spaced apart on the base 1, and are configured to extend vertically upward from the base 1. The two first sliders 5 are respectively installed on the two support columns 4 and can move along the height direction of the support columns 4 (e.g., ...). Figure 1 The guide rail 6 connects two first sliders 5, and the cutting assembly 3 is mounted on the guide rail 6. The two support columns 4 can effectively support the cutting assembly 3; the movement of the sliders along the height direction of the support columns 4 can drive the guide rail 6 and the cutting assembly 3 to move along the height direction of the support columns 4, thereby adjusting the height of the cutting assembly 3 so that the cutting assembly 3 can cut shells 10 of different sizes.
[0043] Furthermore, a baffle 12 is provided at the end of the support column 4 away from the base 1 to prevent the first slider 5 from disengaging from the support column 4.
[0044] Optionally, the cutting device also includes a support base 11, which is detachably mounted on the base 1 and threadedly connected to the support column 4. This configuration allows for a detachable connection between the support column 4 and the base 1, facilitating quick and easy replacement of the support column 4.
[0045] As one embodiment, the slider can be a single-liner linear bearing box-type slider.
[0046] Furthermore, the two ends of the guide rail 6 are detachably mounted on the two first sliders 5.
[0047] To improve the flexibility and cutting efficiency of the cutting assembly 3, the cutting assembly 3 is configured to run along the length direction of the guide rail 6 (e.g., ...). Figure 1 The position (in the middle third direction) is adjustable.
[0048] See Figures 1 to 4The guide rail component 6 includes at least two guide rails 61 connecting the two first sliders 5. The cutting device also includes a connecting member 7 and a second slider 8. The second slider 8 is slidably disposed on the at least two guide rails 61 along the length direction of the guide rail component 6. The connecting member 7 extends radially along the housing 10 and connects the second slider 8 and the cutting assembly 3. The sliding of the second slider 8 along the length direction of the guide rail component 6 can drive the connecting member 7 and the cutting assembly 3 to slide along the length direction of the guide rail component 6, thereby adjusting the position of the cutting assembly 3 and improving the accuracy of the cutting assembly 3. The cooperation between the second slider 8 and the at least two guide rails 61 ensures that the second slider 8 will not rotate relative to the axis of the guide rail 61, thereby improving the stability of the movement of the cutting assembly 3.
[0049] In one embodiment, a single second slider 8 is provided, and two guide rails 61 are provided. Both guide rails 61 pass through the second slider 8 so that the second slider 8 can slide along the length direction of the guide rail 6. Optionally, the second slider 8 is a double-liner type linear bearing box slider.
[0050] As an alternative embodiment, there are two second sliders 8 and two guide rails 61. The two sliders are slidably disposed on the two guide rails 61 in a one-to-one correspondence. One end of the connector 7 is connected to the two second sliders 8, and the other end of the connector 7 is equipped with the cutting component 3.
[0051] Furthermore, the guide rail component 6 also includes two positioning plates 62, which are detachably mounted on the two first sliders 5 respectively. The two positioning plates 62 are connected to both ends of the guide rail 61. The positioning plates 62 connect the first sliders 5 and the guide rail 61 so that the guide rail 61 is fixedly mounted on the first sliders 5 and can move with the first sliders 5.
[0052] As one embodiment, the connector 7 includes a support plate 72, one end of which is connected to the second slider 8, and the other end of which is connected to the cutting assembly 3.
[0053] Furthermore, the connector 7 also includes a horizontal plate 71, which connects multiple second sliders 8 and is mounted on the support plate 72. The horizontal plate 71 connects multiple second sliders 8 together, enabling them to move synchronously.
[0054] To improve the ease of movement of the cutting device, the cutting device also includes multiple casters 9 located at the bottom of the base 1.
[0055] Furthermore, in order to move the cutting device to a suitable height relative to the housing 10, the cutting device also has a lifting member, which connects the moving wheels 9 and the base 1, and is capable of driving the base 1 along the height direction of the support column 4 (e.g., Figure 1 Move in the first direction.
[0056] Meanwhile, by adjusting the position of the cutting device in the horizontal and vertical directions, the housing 10 is placed on the base 1 of the cutting device. In order to prevent the cutting device from moving and causing the housing 10 to be unstable during cutting, the moving wheel 9 also has a fixing component 2. The fixing component 2 can fix the moving wheel 9 and prevent the moving wheel 9 from moving.
[0057] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
