Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, and in particular to a machined lifting equipment and a cleaning machine. Background Technology
[0002] The needle bed is one of the core components of a flat knitting machine (including manual and computerized flat knitting machines). It primarily supports and secures the needle bed, guide rails, and other knitting components. Located inside the machine frame, the needle bed is typically fixed to the base in a triangular or modular structure. The needle bed (for needle placement) is mounted on top, the guide rail supports are connected to the sides, and the bottom is fixed to the base. Residual stress generated during casting or welding can lead to subsequent deformation or cracking of the needle bed. Shot blasting uses high-speed projectiles to impact the surface, causing plastic deformation of the material, offsetting residual tensile stress, forming a compressive stress layer, and improving dimensional stability.
[0003] The needle bed seat has a special shape, and the existing lifting devices are not compatible with it. Therefore, it is easy to shake during the cleaning process after hoisting, and the lifting devices with hooks are not convenient for hanging the needle bed seat. Utility Model Content
[0004] This utility model provides a machining lifting tool and a cleaning machine, which solves the shortcomings of the prior art, such as the special shape of the needle bed seat, the mismatch between the existing lifting tool and the shape of the needle bed seat, the easy shaking during the cleaning process after lifting, and the inconvenience of hanging the needle bed seat with the lifting tool with hook.
[0005] This utility model provides the following technical solution:
[0006] On one hand, this utility model provides a machining lifting tool, including: a hook and a lifting tool body. The lifting tool body includes an upper pressure-bearing part, a column and a lower pressure-bearing part. The upper pressure-bearing part includes a plurality of first circumferential rods radiating outward from the same initial point along the circumference. A top frame forming a ring is provided on the first circumferential rods. A plurality of hooking parts are provided on the top frame. The lower pressure-bearing part includes a plurality of second circumferential rods radiating outward from the same initial point along the circumference. A bottom frame forming a ring is provided on the second circumferential rods. The centers of the first circumferential rods, the top frame, the second circumferential rods and the bottom frame are on the same axis.
[0007] In one possible implementation, the attachment includes a support member with an insertion hole and a limiting member inserted into the insertion hole.
[0008] In one possible implementation, the limiting member includes a top horizontal bar and a first vertical bar, the first vertical bar being fixedly connected to the middle of the horizontal bar, and the lower part of the first vertical bar being provided with a step that fits with the insertion hole.
[0009] In one possible implementation, the top frame and bottom frame are polygonal or circular.
[0010] In one possible implementation, the top frame is a polygonal frame with an outermost interior angle greater than or equal to the angle between the two inclined plates of the needle bed, and the support is located on the extension line from the corner of the top frame to the center.
[0011] In one possible implementation, both the top frame and the bottom frame are polygons, and the corners of the top frame correspond to the middle of the edge of the bottom frame.
[0012] In one possible implementation, the top frame and the bottom frame are both polygons, and their dimensions are set in equal proportions, with the corners of the top frame corresponding one-to-one with the corners of the bottom frame.
[0013] In one possible implementation, the bottom frame includes a plurality of second circumferential rods, a third connecting rod is fixed between adjacent second circumferential rods, and a reinforcing rib is provided between the second circumferential rods and the third connecting rod.
[0014] On the other hand, this utility model also provides a cleaning machine, including a machine body and a gantry frame, wherein an electric hook is provided on the gantry frame, and the electric hook is used to lift the machining tool into the machine body.
[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0016] In this invention, when the needle bed seat is hung on the hanging part, the lower part of the needle bed seat tilts outward. Therefore, after the machining lifting tool is lifted by the hook, the needle bed seat can fit tightly with the machining lifting tool under the action of gravity, avoiding relative displacement between the needle bed seat and the machining lifting tool when shot blasting, thereby improving stability.
[0017] In this invention, the two inclined plates of the needle bed seat press against the polygonal frame of the top frame, forming at least two symmetrically arranged pressing points. Together with the pressing points on the support member, the three points form a support surface, thereby positioning the upper part of the needle bed seat and enabling the needle bed seat to be stably mounted on the machining hanger. When the inner angle of the polygonal frame is equal to the included angle of the two inclined plates of the needle bed seat, the polygonal frame can form line contact with the two inclined plates of the needle bed seat, thus making it more stable.

[0030] To better understand the purpose, function, and specific design scheme of this utility model, the machining lifting tool and cleaning machine of this utility model will be described in further detail below with reference to the accompanying drawings.
[0031] Reference Figures 1-4 In some embodiments, the present invention provides a cleaning machine, including a machine body and a gantry frame, wherein an electric hook is provided on the gantry frame, and the electric hook is used to lift the lower machining fixture into the machine body.
[0032] In the above embodiment, a guide rail facing the machine body is provided on the gantry frame, an electric hoist is installed on the guide rail, and a liftable hook is installed on the electric hoist. A through groove is provided on the top of the machine body for the hook to pass through. The machining fixture with the needle bed seat 14 already attached is lifted by the hook and moved into the machine body. After the machine body is closed, the needle bed seat 14 on the machining fixture is shot blasted cleaned by a cleaning machine.
[0033] In some embodiments, the present invention provides a machining lifting tool, comprising: a hook 1 and a lifting tool body, the lifting tool body comprising an upper pressure-bearing part, a column 6 and a lower pressure-bearing part, the upper pressure-bearing part comprising a plurality of first circumferential rods 2 radiating outward from the same initial point along the circumference, the first circumferential rods 2 being provided with a top frame 4 forming an annular shape, the top frame 4 being provided with a plurality of hooking parts, the lower pressure-bearing part comprising a plurality of second circumferential rods 7 radiating outward from the same initial point along the circumference, the second circumferential rods 7 being provided with a bottom frame 8 forming an annular shape, the centers of the first circumferential rods 2, the top frame 4, the second circumferential rods 7 and the bottom frame 8 being on the same axis.
[0034] In the above embodiment, when the needle bed 14 is hung on the hanging part, the lower part of the needle bed 14 is tilted outward. Therefore, after the machining lifting tool is lifted by the hook, the needle bed 14 can fit tightly with the machining lifting tool under the action of gravity, avoiding relative displacement between the needle bed 14 and the machining lifting tool when shot blasting, thereby improving stability.
[0035] In some embodiments, the mounting portion includes a support member 5, which has an insertion hole 10. A limiting member is inserted into the insertion hole 10. For example, the support member 5 can be a plate or a rod. Specifically, in this embodiment, a plate is selected as the support member 5. The width of the plate is slightly smaller than the top through groove 16 of the needle bed 14 so that the support member 5 can pass smoothly through the top through groove 16 of the needle bed 14. Then, the limiting member is inserted into the insertion hole 10 to limit the needle bed 14.
[0036] In some embodiments, the limiting member includes a top horizontal bar 11 and a first vertical bar 12. The first vertical bar 12 is fixedly connected to the middle of the horizontal bar 11. The lower part of the first vertical bar 12 is provided with a step that fits with the insertion hole 10. For example, the specific shape of the horizontal bar 11 and the first vertical bar 12 does not need to be limited. Specifically, in this embodiment, the horizontal bar 11 and the first vertical bar 12 are both steel bars. The horizontal bar 11 and the first vertical bar 12 are welded together. A second vertical bar 13 is fixed to one side of the lower part of the first vertical bar 12 to form a step.
[0037] In the above embodiment, the horizontal bar 11 is arranged horizontally, and the first vertical bar 12 and the second vertical bar 13 are arranged vertically, with the second vertical bar 13 located on one side of the first vertical bar 12. By matching the size of the insertion hole 10 with the first vertical bar 12 and the second vertical bar 13, the size of the horizontal bar 11 is at least larger than the width of the top through groove 16 of the needle bed 14. When the first vertical bar 12 and the second vertical bar 13 are inserted into the insertion hole 10, the first vertical bar 12 and the second vertical bar 13 form a limiting step. Therefore, under the action of external force (shot blasting), the limiting part is not easy to come out of the insertion hole 10. Furthermore, since the size of the horizontal bar 11 is larger than the width of the top through groove 16 of the needle bed 14, the needle bed 14 will not separate from the machining hanger if the limiting part is not removed.
[0038] In some embodiments, the top frame 4 and the bottom frame 8 are polygonal or circular.
[0039] When the top frame 4 is polygonal, the inner side of the inclined plate 15 of the needle bed 14 presses against the edge of the top frame 4, thereby supporting the needle bed 14. Then, the positioning is completed through the hook part, thereby fixing the upper end of the needle bed 14.
[0040] In some embodiments, the top frame 4 is a polygonal frame with an outermost inner angle greater than or equal to the angle between the two inclined plates 15 of the needle bed 14, and the support member 5 is located on the extension line from the corner to the center of the top frame 4, so that when the needle bed 14 is mounted on a machining hanger, the polygonal frame can provide support for the upper part of the needle bed 14.
[0041] In the above embodiment, the two inclined plates 15 of the needle bed 14 press against the polygonal frame of the top frame 4, forming at least two symmetrically arranged pressing points. Together with the pressing points on the support member 5, the three points form a support surface, thereby positioning the upper part of the needle bed 14 so that the needle bed 14 can be stably hung on the machining hanger. When the inner angle of the polygonal frame is equal to the included angle of the two inclined plates 15 of the needle bed 14, the polygonal frame can form a line contact with the two inclined plates 15 of the needle bed 14, thus making it more stable.
[0042] In some embodiments, the top frame 4 and the bottom frame 8 are both polygons, and the corners of the top frame 4 correspond to the middle of the edge of the bottom frame 8.
[0043] In the above embodiment, when the needle bed 14 is hung on the hanging part, the upper part of the needle bed 14 presses against the corner of the top frame 4, and the lower part of the needle bed 14 presses against the middle of the edge of the bottom frame 8.
[0044] In some embodiments, the top frame 4 and the bottom frame 8 are both polygons, and their dimensions are set in equal proportions. The corners of the top frame 4 correspond one-to-one with the corners of the bottom frame 8.
[0045] In the above embodiment, by setting the top frame 4 and the bottom frame 8 in equal proportions, the corners of the top frame 4 and the bottom frame 8 can correspond one-to-one. The support member 5 is set at the corner of the top frame 4. When the machining hoist hangs the needle bed seat 14, the inclined plate 15 on the upper part of the needle bed seat 14 contacts the corner of the top frame 4, and the inclined plate 15 on the lower part of the needle bed seat 14 contacts the corner of the bottom frame 8. On the one hand, it can play a supporting role, and on the other hand, it can prevent the needle bed seat 14 from swinging along the tangent direction of the corner of the top frame 4 and the bottom frame 8. In addition, it can also make the adjacent needle bed seats 14 evenly spaced, making the shot blasting cleaning process more uniform and stable after lifting.
[0046] In some embodiments, the top frame 4 includes a plurality of first circumferential rods 2, and a first connecting rod and a second connecting rod 3 forming a polygonal frame are provided between adjacent first circumferential rods 2. A column 6 is provided on the second connecting rod 3, and the lower end of the column 6 is fixedly connected to the bottom frame 8. The bottom frame 8 includes a plurality of second circumferential rods 7, and a third connecting rod forming a polygonal frame is provided between adjacent second circumferential rods 7.
[0047] Specifically, in one embodiment, the top frame 4 includes six first circumferential rods 2. One end of each of the six first circumferential rods 2 is fixedly connected to the other end, and the other end extends outward. The spacing between the six first circumferential rods 2 is evenly distributed. Six first connecting rods are fixedly attached to the ends of the six first circumferential rods 2 in sequence. The two ends of each first connecting rod are fixedly connected to the ends of the adjacent first circumferential rods 2. Therefore, the six first connecting rods form an annular hexagonal frame. Six second connecting rods 3 are provided inside the first connecting rods. The six second connecting rods 3 form a hexagonal frame with the first connecting rods at the same center. The second connecting rods 3 correspond one-to-one with the first connecting rods.
[0048] Adjacent first connecting rods form a corner, the interior angle of which is greater than or equal to the included angle formed by the two inclined plates 15 of the needle bed 14. A support plate is fixed at each corner, the support plate is arranged along the length direction of the first circumferential rod 2, and an insertion hole 10 is provided on the support plate. The insertion hole 10 is a strip-shaped hole, the length direction of which is consistent with the length direction of the support plate. A limiting member is inserted into the insertion hole 10. The limiting member includes a horizontal rod 11, a first vertical rod 12 is fixed in the middle of the horizontal rod 11, and a second vertical rod 13 is fixed on one side of the lower part of the first vertical rod 12 along the orthogonal direction of the horizontal rod 11. The top of the second vertical rod 13 forms a step with the first vertical rod 12, thereby forming a limiting member.
[0049] Each second link 3 has a column 6 fixed in the middle. The bottom of the column 6 is fixedly connected to the bottom frame 8. The bottom frame 8 includes six second circumferential rods 7. A third link is fixed between adjacent second circumferential rods 7. The six third links form a ring-shaped hexagonal frame. The lower end of the column 6 is fixedly connected to the second circumferential rods 7.
[0050] A reinforcing rib 9 is provided between the second circumferential rod 7 and the third connecting rod, and the reinforcing rib 9 and the second circumferential rod 7 are arranged in a fishbone shape;
[0051] In the above embodiments, the top frame 4 and column 6 forming a ring, as well as the bottom frame 8 forming a ring, the limiting member, and the reinforcing bar 9 are all steel bars.
[0052] Based on the above-mentioned equipment, the present invention generally includes the following steps during use.
[0053] First, place the lifting device on the ground and remove all the limiting parts on the hook-and-loop connection.
[0054] The second step is to lift the needle bed 14 using the lifting structure, with the inner side of the inclined plate 15 of the needle bed 14 facing the hanging part, and then place the lower end of the needle bed 14 near the lifting device.
[0055] The third step is to slowly bring the upper end of the needle bed 14 close to the hook part, so that the top through groove 16 of the upper end of the needle bed 14 is sent into the support member 5, and then the limiting member is inserted into the insertion hole 10.
[0056] The fourth step is to symmetrically attach the upper ends of each needle bed seat 14 to the attachment part of the hanger in sequence, thereby completing the attachment work;
[0057] The fifth step involves using the electric hoist and hook on the shot blasting machine to lift the lifting device into the machine for shot blasting.
[0058] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
