Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment auxiliary tooling, in particular to a lifting and quenching tooling for solid large disc parts. Background Art

[0002] When the mass of solid disc parts is less than the magnetic suction range, the parts are sucked up by a magnetic suction cup and placed in a material frame. The material frame and the parts are then put into the furnace together. The parts and the material frame are heated at the same time. During quenching, the parts and the material frame are cooled together with the quenching medium. This method has many operating procedures. When the parts are sucked by magnets, they are easy to slip when they are heavy or the suction position is unbalanced, which poses certain safety hazards. At the same time, the material frame also absorbs heat, resulting in energy waste. The material frame also consumes quenching liquid during cooling. The mass of solid disc parts to be processed is limited. When their mass exceeds the magnetic suction range, they cannot be sucked by magnets. Only soft ropes can be used for room temperature lifting, but quenching lifting and transfer operations cannot be completed. Or when the disc diameter is larger, it cannot be loaded by the material frame.

[0003] Patent application number CN201310122171.7 discloses a quenching frame, including a frame, wherein the frame is connected by a mutually symmetrical first frame and a second frame to form a quadrilateral, a bottom frame is arranged at the lower part of the frame, and a heat equalization device is also connected to the bottom frame inside the frame. The utility model greatly improves the heat dissipation performance of the present invention by arranging steel wire meshes of uniform volume at intervals on the frame, greatly reduces weight and saves costs, and has a relatively uniform heat absorption performance. A hinge is arranged on one side of the frame to fold the frame, so that the operator can easily place the cast aluminum alloy that needs to be quenched into the frame. When the quadrilateral frame composed of this material frame is suitable for solid large disc parts, an area much larger than the large disc must be processed to place the large disc workpiece therein, but the bottom surface of the large disc is also closely attached to the bottom surface of the hanging frame, so that the bottom surface cannot directly contact the quenching liquid, and the huge material frame must also increase the volume of the quenching pool, otherwise the quenching cannot be completed, which causes an increase in construction costs.

[0004] Another patent application number CN201721056209.5 proposes a large-size disc-type parts clamping device for a vertical quenching machine, including a three-jaw chuck and an attached jaw arranged on the three-jaw chuck, the ratio of the attached jaw length to the outer diameter of the workpiece is greater than 1 / 6, the head end of the attached jaw is connected to the large bevel gear inside the three-jaw chuck through a universal three-jaw interface, and an adjustment mechanism is arranged on the side of the three-jaw chuck, the adjustment mechanism is connected to the small bevel gear wrench mouth inside the three-jaw chuck, and the large bevel gear is meshed with the small bevel gear; the lower side of the tail end of the attached jaw is connected to the linear slide rail, and the linear slide rail is movably arranged on the support. This patent document is suitable for large-size annular discs, and the inner ring of the annular disc is used for centering and positioning, and the outer peripheral surface of the disc workpiece is quenched using high-frequency electromagnetic heating, but it is not suitable for the overall quenching operation of solid large discs.

[0005] In view of the above, it is necessary to propose a lifting and quenching tool for solid large disc parts to solve the above problems. Utility Model Content

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1: A lifting and quenching tool for a solid large disc part, comprising a top lifting structure 1 for connecting to a crane, frame-shaped hanger structures 2 are symmetrically arranged on both sides of the top lifting structure 1, and the frame-shaped hanger structures 2 on both sides are used to support a large disc part 3;

[0031] In this embodiment, the tooling is mainly divided into two parts, specifically, Figure 1-3 As shown, the upper part is the top lifting structure 1, which is a lifting ring 5 in this embodiment, and the lower part is two symmetrically arranged frame-like hanger structures 2, wherein the frame-like hanger structures 2 at least include a bottom supporting beam 4, and the frame-like hanger structures 2 on both sides support the two sides of the bottom surface of the large disc through the two bottom supporting beams 4.

[0032] like Figure 2As shown, the frame-shaped hanger structure 2 also includes a vertical portion 6 and an inclined portion 7. The two ends of the bottom supporting crossbeam 4 are respectively vertically connected to the vertical portion 6, and the upper ends of the vertical portions 6 on both sides are respectively connected to the inclined portions 7. The upper ends of the inclined portions 7 on both sides are connected to form a hanging portion 8, and the hanging ring 5 is set through the hanging portion 8. In this embodiment, the frame-shaped hanger forms an isosceles triangle in the upper part, and is connected to form a rectangular structure (removing the upper side of the rectangle) at the lower side; a plurality of horizontal support rods 9 are arranged in parallel between the inclined portions 7 on both sides, that is, a plurality of horizontal supports are connected between the two side edges of the isosceles triangle to fix the shape, namely, the horizontal support rods 9.

[0033] like Figure 3 As shown, two frame-shaped hanger structures 2 are arranged on a hanging ring 5, and are hung on the hanging ring 5 through the hanging part 8, so that the height positions of the bottom supporting beams 4 on both sides overlap.

[0034] The overall structure of the tooling in this embodiment is simple, and the raw materials and processing costs are low. When lifting and transporting, the operator hangs the upper lifting ring 5 on the crane, and the two symmetrical devices are in a side-by-side vertical state. The crane is lifted to the top of the large disc part 3. The operator only needs to pull open the frame-shaped hanger structures 2 on both sides and move the crane downward until the bottom supporting beams 4 at the bottom of the two frame-shaped hanger structures 2 are against the bottom of the disc, and the vertical parts 6 on both sides are against the periphery of the large disc part 3, and maintain a symmetrical state to ensure that the large disc part 3 is stable during lifting and transportation.

[0035] This type of disc parts lifting tooling is widely used, the raw materials are easy to obtain, the production cost is low, the operation is simple and convenient, which greatly reduces the labor intensity of the operator and improves work efficiency.

[0036] Embodiment 2: There is only one point of contact between the frame-like hanger structure 2 and the top lifting structure 1 (i.e., the lifting ring 5) introduced in the aforementioned embodiment 1. When the frame-like hanger structures 2 on both sides are opened, they cannot be opened in parallel, which inevitably causes lateral deflection. If the frame-like hanger structures 2 on both sides are to be opened in parallel, multiple people are required to cooperate and pull open the two frame-like hanger structures 2 from both sides at the same time, which requires the investment of multiple manpower for better use.

[0037] As an improvement, Figure 4As shown, the frame-like hanger structure 2 includes a vertical portion 6, an inclined portion 7, and the vertical portions 6 are connected at both ends of the bottom supporting beam 4. Similar to the first embodiment, the bottom supporting beam 4 is used to hold up the two large discs, with the difference that the upper ends of the vertical portions 6 on both sides are connected to the inclined portions 7, and the inclined portions 7 on both sides are arranged parallel to each other. The upper ends of the inclined portions 7 are provided with a first hinged ear 10, and the frame-like hanger structure 2 is hinged to the top lifting structure 1 through the first hinged ear 10; in this embodiment, two connection points are formed between the frame-like hanger structure 2 on each side and the top lifting structure 1. Compared with one connection point in the first embodiment, the stability during the opening or closing process can be improved, and the lateral deflection of the frame-like hanger structure 2 when opened can be avoided. Specifically, the top lifting structure 1 includes a top crossbeam 11, and first hinged seats 12 are provided on both sides of the top crossbeam 11. The two first hinged ears 10 at the upper end of the frame-like hanger structure 2 are hingedly connected in the first hinged seats 12; in actual use, if manpower is used to open the frame-like hanger structure 2, this structure only requires two people to pull the frame-like hanger structures 2 on both sides respectively, that is, the bottom supporting beams 4 on both sides can be controlled to open relatively parallel; in embodiment one, at least four people are required to stand at the four corners of the lifting tooling and pull at the same time to make the bottom supporting beams 4 open in parallel.

[0038] As an improvement, in this embodiment, the frame-shaped hanger structures 2 on both sides are controlled to open automatically at the same time when they land, thereby further reducing the manual operation of the operator. Figure 4 , 6 As shown, a suspension rod 13 is provided vertically through the top cross beam 11, and the suspension rod 13 and the top cross beam 11 are slidably connected. The lifting clamping mechanism 14 is controlled by the push and pull of the suspension rod 13 and drives the frame-shaped hanger structures 2 on both sides to open or close and rotate in a mirror-image manner.

[0039] Specifically, the lifting and clamping mechanism 14 includes a lifting shaft 15, the lower end of the suspension rod 13 is connected to the lifting shaft 15, the lifting shaft 15 is driven by the suspension rod 13, and is pulled up by the suspension rod 13 when lifting, and is pulled downward by the frame-shaped suspension frame structures 2 on both sides relative to the top cross beam 11 when falling to the ground;

[0040] A transverse support rod 9 is provided between the two parallel inclined portions 7 of the frame-shaped hanger structure 2, and the transverse support rod 9 is connected to the lifting shaft 15 through a connecting rod 16, and both ends of the connecting rod 16 are rotatably connected to the transverse support rod 9 and the lifting shaft 15; at least four connecting rods 16 are symmetrically provided between the lifting shaft 15 and the frame-shaped hanger structures 2 on both sides; Figure 4 As shown, four connecting rods 16 are rotatably connected to the lifting shaft 15, two of which are connected to the frame-like hanger structure 2 on one side, and the other two are connected to the frame-like hanger structure 2 on the other side. It can be understood that Figure 7As shown in FIG. 1 , when the tooling falls, the bottom crossbeam touches the ground first, thereby providing support force to the bottom crossbeam; since the suspension rod 13 and the top crossbeam 11 are slidably connected, the lifting shaft 15 continues to fall relative to the top crossbeam 11, that is, the distance between the two increases. In the process of continuing to fall, the frame-shaped hanger structure 2 is affected by its own gravity G. As the top crossbeam continues to fall, the frame-shaped hanger structure 2 is driven to open at the first hinge seat 12, and a thrust F is formed on the bottom crossbeams on both sides. Figure 7 As shown by the arrow in the middle, in this improved example, after the tooling is on the ground, it can be opened automatically, and the spacing between the bottom supporting beams 4 on both sides is larger than the diameter of the large disc part 3, so that the bottom supporting beams 4 can be supported on the bottom of the large disc part 3. On the contrary, when lifting, the overall force is the same as Figure 7 The directions of the forces shown are opposite, and the suspension rods 13 on both sides apply the lifting force to the lifting shaft 15. Due to the sliding connection between the suspension rods 13 and the top beam 11, the lifting shaft 15 moves upward relative to the top beam 11. When the lifting shaft 15 moves upward, the frame-like hanger structures 2 on both sides are pulled to close in the direction of approaching each other through the connecting rods 16 on both sides, so that the vertical parts 6 on both sides can be firmly attached to the side walls of the large disc part 3, forming a clamping of the side walls of the large disc part 3, thereby forming a good clamping, positioning and locking effect, and then when continuing to lift, the large disc part 3 can be hoisted and lifted through the bottom supporting beam 4.

[0041] Furthermore, the suspension rod 13 is provided with two parallel ends passing through the two ends of the cross beam, and a lifting ring 5 is provided at the upper end of the suspension rod 13; the suspension rod 13 is provided with an upper limit block 26 and a lower limit block 27 with adjustable height, and the upper limit block 26 and the lower limit block 27 are respectively located on the upper and lower sides of the cross beam. In actual use, the setting of the two suspension rods 13 can make the entire tooling be lifted more balanced, and the upper limit block 26 and the lower limit block 27 set on the suspension rod 13 can control the maximum angle of opening or closing of the frame-shaped hanger structure 2 on both sides. Figure 7 As shown, when falling, the suspension rod 13 moves downward to open the frame-like hanger structures 2 on both sides. Due to the setting of the upper limit block 26, the degree of downward movement of the suspension rod 13 is limited, thereby preventing the frame-like hanger structures 2 on both sides from opening too much (it can be understood that when the connecting rods 16 on both sides are pulled into a straight line, the opening of the frame-like hanger structure 2 is also limited. The difference is that the setting of the upper limit block 26 can prevent the connecting rods 16 on both sides from crossing the horizontal line to form a reverse fold); when rising, the lower limit block 27 moves up and is stuck at the bottom of the top crossbeam 11, and the entire tooling is pulled up. The optimal position of the lower limit block 27 varies according to the diameter of the large disc part 3. Specifically, when lifting, it is advisable to make the lifting force act on the top crossbeam 11 through the lower limit block 27, so that the cross support rod 9 will not be pulled inward by the connecting rod 16 during the lifting process, reducing the lateral pressure perpendicular to the inclined portion 7. The advantage is that the inclined portion 7 can be prevented from bending and deforming inward after long-term lifting.

[0042] In actual use, the crane moves the entire tooling to above the large disc part 3 to be hoisted, and then controls the tooling to fall. Due to the setting of the lower limit block 27, the frame-shaped hanger structures 2 on both sides maintain a certain opening during the falling process of the tooling. As the tooling lands on the workpiece, the frame-shaped hanger structures 2 on both sides continue to open under the action of gravity until they pass the diameter position of the large disc part 3, so that the bottom supporting beam 4 is stuck on both sides of the workpiece; then the suspension rod 13 is pulled upward, so that the suspension rod 13 pulls the lifting shaft 15 to move upward relative to the top beam 11, so that the frame-shaped hanger structures 2 on both sides are retracted, and then The bottom supporting beams 4 on both sides are supported on the lower surface of the large disc workpiece. Under the clamping force of the vertical parts 6 of the frame-like hanger structures 2 on the large disc workpiece, the disc workpiece can be automatically centered and clamped, thereby forming the accuracy of clamping the disc workpiece; then continue to pull the hanging rod 13, and when the lower limit block 27 is stuck on the lower side of the top beam 11, it is clamped in place, and then the large disc part 3 can be lifted. The whole process does not require personnel to pull the frame-like hanger structures 2 on both sides, and the disc workpiece can be automatically centered and clamped. It only needs to manually adjust the position of the lower limit block 27 according to the diameter of the disc.

[0043] As an embodiment of the upper limit block 26 and the lower limit block 27, threads can be processed on the surface of the suspension rod 13 so that the upper limit block 26 and the lower limit block 27 are both screwed to the suspension rod 13, so that the upper limit block 26 and the lower limit block 27 can be adjusted to various precise positions.

[0044] As another embodiment of the upper limit block 26 and the lower limit block 27, when the processed large disc part 3 has a fixed diameter or several specifications, the suspension rod 13 can be provided with a corresponding through hole, and the upper limit block 26 and the lower limit block 27 can be provided as an insertion rod structure, so that the upper limit block 26 and the lower limit block 27 can be inserted into the through hole accordingly.

[0045] Embodiment 3: This embodiment is improved on the basis of the structure of embodiment 2. Specifically, Figure 5 , 6 As shown, an automatic clamping structure 17 is provided between the bottom supporting cross beam 4 and the vertical parts 6 on both sides. When the large disc part 3 is hoisted, the automatic clamping structure 17 clamps and fixes it by using the deadweight of the large disc part 3. In the second embodiment, the vertical part 6 forms a lateral centering clamp on the side wall of the large disc. The improved automatic clamping structure 17 in this embodiment can clamp the large disc part 3 in the up and down directions during the hoisting process, thereby firmly positioning the workpiece during the hoisting process.

[0046] Specifically, Figure 5 , 6As shown, the automatic clamping structure 17 includes a lever arm 18, a bending portion 19 is provided at both ends of the bottom supporting cross beam 4, a pivot shaft 20 is provided at the upper end of the bending portion 19, a second hinge seat 21 is provided at the lower end of the vertical portion 6, one end of the lever arm 18 is a hinge end, and the other end is a clamping end, the hinge end is provided with a second hinge ear 22, the second hinge ear 22 is hingedly connected in the second hinge seat 21, the clamping end is used to clamp on the upper end surface of the large disc part 3, a waist hole 23 is provided in the middle of the lever arm 18, the pivot shaft 20 is arranged through the waist hole 23 and is connected to form a notch. In actual use, the lever principle is used to apply force to the hinge end, and the large disc part 3 is clamped at the clamping end, and the force at the hinge end is the force applied by the large disc's own weight during the process of lifting the large disc part 3, so the effect of fixing its own position by its own weight can be formed. The clamping end is bent downward to form an L-bend 24 , and a pressing wheel 25 is rotatably connected to the clamping end. The L-bend 24 allows the clamping end to contact the surface of the large disc part 3 , and the pressing wheel 25 contacts the surface thereof.

[0047] During actual use, when the tooling falls to the ground, the bottom supporting beam 4 touches the ground, so that the pivot shafts 20 at both ends act on the waist hole 23, and the lever arm 18 is lifted, so that the large disc workpiece can enter the bottom supporting beam 4; when lifting the workpiece, first pull the vertical part 6 to lift it, and then pull the hinged end of the lever arm 18 through the second hinge seat 21, and make it rotate with the pivot shaft 20 as the axis, so that the clamping end at the other end is pressed on the surface of the large disc part 3. After the workpiece leaves the ground, the dead weight of the large disc part 3 all acts on the bottom supporting beam 4, and then converts its dead weight into downward pressure to clamp the workpiece, making it more firmly fixed and avoiding loosening during the lifting process.

[0048] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
