Description

Technical Field

[0001] This utility model specifically relates to a heat treatment support frame for irregularly shaped large castings. Background Technology

[0002] During the casting process, different cooling rates in different parts of the anchor casting can generate internal stress, leading to warping and cracking. Heat treatment can eliminate these internal stresses, stabilize the dimensions of the casting, and also alter the hardness and toughness of the anchor casting, making it easier to machine.

[0003] In existing technologies for heat treatment of ship anchor castings, due to the irregular shape of the castings, multiple sets of pads are placed on the heat treatment support platform to facilitate placement and ensure uniform heating during heat treatment. However, these pads are mostly fixed, making adjustment difficult and hindering the support of different anchor castings, thus reducing the practicality of the device. Therefore, to address these technical problems, a heat treatment support frame for irregularly shaped large castings is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a heat treatment support frame for irregularly shaped large castings, which facilitates the adjustment of the position of the pad body, thereby making it easier to support different anchor castings and improving the practicality of the device.

[0005] A support frame for heat treatment of irregularly shaped large castings includes a support platform and a pad block mechanism, wherein the pad block mechanism includes:

[0006] The pad body is provided in multiple sets, and all sets of the pad body are disposed on the top surface of the bearing platform and can slide along its length; and

[0007] The drive assembly includes a rotating shaft, gears, worm gears, worms, and racks. The rotating shaft is rotatably mounted on the pad body. Worms are mounted at both ends of the rotating shaft, and the two sets of worms rotate in opposite directions. Worm gears are rotatably mounted at both ends of the pad body. The worms and worm gears at the same end mesh with each other. The bottom ends of the two sets of worm gears are coaxially connected to the gears. Racks are mounted on both long sides of the bearing platform, and the two sets of gears mesh with the two sets of racks respectively.

[0008] The beneficial effects of the aforementioned heat treatment support frame for large irregular-shaped castings are as follows:

[0009] By rotating the shafts on the multiple sets of pad bodies, the rotation of the shafts drives the rotation of two sets of worm gears. The rotation of the two sets of worm gears meshes with two sets of worm wheels, driving the two sets of worm wheels to rotate in opposite directions. The opposite rotation of the two sets of worm wheels drives the opposite rotation of two sets of gears. The opposite rotation of the two sets of gears meshes with two sets of racks, thus driving the pad body to move along the length of the bearing platform. Stopping the rotation of the shafts stops the rotation of the two sets of worm gears. At this time, the two sets of worm gears mesh with the two sets of worm wheels to fix the gears, thereby fixing the pad body. The movement and fixing of the pad body are convenient, and the position of the pad body can be easily adjusted, thus facilitating the support of different anchor castings and improving the practicality of the device.

[0010] In one embodiment, the top surface of the support platform has two sets of T-shaped grooves facing each other, and the bottom ends of the multiple sets of pad bodies are each provided with two sets of T-shaped sliders facing each other. The two sets of T-shaped sliders can slide within the two sets of T-shaped grooves along the length direction of the support platform. By providing T-shaped grooves and T-shaped sliders, the sliding of the pad body in the vertical direction and along the width direction of the support platform can be restricted, thereby improving the stability of the pad body sliding along the length direction of the support platform.

[0011] In one embodiment, an anti-detachment component is also included. The anti-detachment component is provided on both wide sides of the support platform. Each anti-detachment component includes a drive member and two sets of baffles. The two sets of baffles are disposed opposite each other on one wide side of the support platform and can slide along its width. The drive member is rotatably disposed on the support platform and connected to the two sets of baffles. Rotating the drive member drives the two sets of baffles to move closer or further apart, so that the two sets of baffles open or close the openings at one end of the two sets of T-shaped grooves. By rotating the drive member to move the two sets of baffles away from each other and close the openings at the ends of the T-shaped grooves, the T-shaped slider can be prevented from sliding out of the T-shaped grooves when adjusting the position of the pad body. By rotating the drive member to move the two sets of baffles closer together and open the openings at the ends of the T-shaped grooves, the T-shaped slider can slide out or into the T-shaped grooves, thus facilitating the disassembly or addition of the pad body as needed, further improving the practicality of the device.

[0012] In one embodiment, the driving component includes a bidirectional screw; the bidirectional screw is disposed along the width direction of the bearing platform and rotatably mounted on the bearing platform, with each end of the bidirectional screw threadedly connected to two sets of baffles. Rotating the bidirectional screw in connection with the two sets of baffles drives the two sets of baffles to move relatively away, while rotating the bidirectional screw in the opposite direction drives the two sets of baffles to move relatively closer, making it convenient to move the two sets of baffles relatively away or closer.

[0013] In one embodiment, two sets of limiting grooves are provided on both wide sides of the bearing platform, and limiting sliders are provided on the two sets of baffles. The two sets of limiting sliders can slide in the two sets of limiting grooves along the width direction of the bearing platform.

[0014] In one embodiment, anti-slip plates are detachably mounted on the tops of multiple sets of pad bodies. By providing anti-slip plates, horizontal movement of the anchor casting when placed on multiple sets of pad bodies can be prevented, improving the stability of the anchor assembly on the device. Furthermore, the anti-slip plates protect the top surfaces of the pad bodies from impact damage caused by the anchor casting. The detachable nature of the anti-slip plates facilitates individual replacement if damaged, reducing the cost of using the device.

[0015] In one embodiment, the bottom end of the anti-slip plate is provided with multiple sets of positioning posts spaced apart along its length, and the top end of the pad body is provided with multiple sets of positioning holes corresponding to the multiple sets of positioning posts, and the multiple sets of positioning posts can be inserted into the multiple sets of positioning holes. By setting multiple sets of positioning posts and multiple sets of positioning holes to cooperate, the horizontal sliding of the anti-slip plate can be restricted, thereby improving the stability of the anti-slip plate installed on the top surface of the pad body.

[0016] In one embodiment, both ends of the rotating shaft are equipped with coaxially connected rocker wheels. The rocker wheels facilitate operation, allowing the operator to easily and effortlessly drive the shaft. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] Please see Figures 1 to 3 One embodiment of the heat treatment support frame for irregularly shaped large castings includes a support platform 10 and a pad block mechanism, the pad block mechanism including a pad block body 20 and a drive assembly 30.

[0030] The pad body 20 is provided in multiple sets, all of which are set on the top surface of the bearing platform 10 and can slide along its length. The drive assembly 30 includes a rotating shaft 301, a gear 302, a worm gear 303, a worm 304, and a rack 305. The rotating shaft 301 is rotatably provided on the pad body 20. Worms 304 are provided at both ends of the rotating shaft 301. The two sets of worms 304 rotate in opposite directions. Worms 303 are rotatably provided at both ends of the pad body 20. The worms 304 and worm gears 303 at the same end mesh. The bottom ends of the two sets of worm gears 303 are coaxially connected to the gears 302. The two long sides of the bearing platform 10 are provided with racks 305. The two sets of gears 302 mesh with the two sets of racks 305 respectively.

[0031] In the above embodiment, by rotating the shafts 301 on the multiple sets of pad bodies 20, the rotation of the shafts 301 drives the two sets of worm gears 304 to rotate. The rotation of the two sets of worm gears 304 meshes with the two sets of worm wheels 303, driving the two sets of worm wheels 303 to rotate in opposite directions. The opposite rotation of the two sets of worm wheels 303 drives the two sets of gears 302 to rotate in opposite directions. The opposite rotation of the two sets of gears 302 meshes with the two sets of racks 305, thereby driving the pad body 20 to move along the length direction of the bearing platform 10. When the rotation of the shafts 301 is stopped, the two sets of worm gears 304 stop rotating. At this time, the two sets of worm gears 304 mesh with the two sets of worm wheels 303 to fix the gears 302, thereby fixing the pad body 20. The movement and fixing of the pad body 20 are convenient, and the position of the pad body 20 is easy to adjust, which facilitates the bearing of different anchor castings and improves the practicality of the device.

[0032] Based on the above embodiments, further, both ends of the rotating shaft 301 are provided with coaxially connected rocker wheels 306. By providing rocker wheels 306, it is convenient for the operator to hold the rocker wheels 306 to drive the rotating shaft 301 to rotate, making it convenient and labor-saving to drive the rotating shaft 301 to rotate.

[0033] Please see Figure 2 and Figure 3 In one embodiment, the top surface of the support platform 10 is provided with two sets of T-shaped grooves 101 facing each other, and the bottom ends of the multiple sets of pad bodies 20 are provided with two sets of T-shaped sliders 201 facing each other. The two sets of T-shaped sliders 201 can slide along the length of the support platform 10 and are disposed in the two sets of T-shaped grooves 101.

[0034] In the above embodiments, by opening a T-shaped groove 101 and cooperating with a T-shaped slider 201, the sliding of the pad body 20 in the vertical direction and along the width direction of the bearing platform 10 can be restricted, thereby improving the stability of the pad body 20 sliding along the length direction of the bearing platform 10.

[0035] Please see Figure 2 and Figure 4 In one embodiment, it also includes an anti-detachment component 40. The anti-detachment component 40 is provided on both wide sides of the support platform 10. The anti-detachment component 40 includes a driving member and two sets of baffles 403. The two sets of baffles 403 are disposed opposite to each other on one wide side of the support platform 10 and can slide along its width direction. The driving member is rotatably disposed on the support platform 10 and connected to the two sets of baffles 403. Rotating the driving member can drive the two sets of baffles 403 to move closer or further away from each other, so that the two sets of baffles 403 open or block the openings at one end of the two sets of T-shaped slide grooves 101.

[0036] Specifically, the two wide sides of the bearing platform 10 are provided with two sets of limiting slide grooves 102, and the two sets of baffles 403 are provided with limiting sliders 402. The two sets of limiting sliders 402 can slide in the two sets of limiting slide grooves 102 along the width direction of the bearing platform 10.

[0037] In the above embodiments, by rotating the drive member to move the two sets of baffles 403 away from the opening at the end of the T-shaped slide groove 101, the T-shaped slider 201 can be prevented from sliding out of the T-shaped slide groove 101 when adjusting the position of the pad body 20. By rotating the drive member to move the two sets of baffles 403 closer to the opening at the end of the T-shaped slide groove 101, the T-shaped slider 201 can slide out of or into the T-shaped slide groove 101, thereby facilitating the disassembly or addition of the pad body 20 as needed, and further improving the practicality of the device.

[0038] Based on the above embodiments, the driving component further includes a bidirectional screw 401; the bidirectional screw 401 is arranged along the width direction of the bearing platform 10 and is rotatably arranged on the bearing platform 10, and both ends of the bidirectional screw 401 are threadedly connected to two sets of baffles 403 respectively.

[0039] By rotating the bidirectional screw 401 and engaging it with the threaded connection of the two sets of baffles 403, the two sets of baffles 403 can be driven to move away from each other. By rotating the bidirectional screw 401 in the opposite direction and engaging it with the threaded connection of the two sets of baffles 403, the two sets of baffles 403 can be driven to move closer to each other. It is convenient to drive the two sets of baffles 403 to move away from each other or closer to each other.

[0040] Please see Figure 2 and Figure 3 In one embodiment, anti-slip plates 50 are detachably mounted on the top of each of the multiple pad body 20. Specifically, bolts are provided at both ends of the anti-slip plates 50, and the two sets of bolts are threadedly connected to both ends of the pad body 20.

[0041] In the above embodiments, by setting the anti-slip plate 50, on the one hand, the horizontal movement of the anchor casting when it is placed on multiple sets of pad bodies 20 can be avoided, thus improving the stability of the anchor assembly placed on the device. On the other hand, it can protect the top surface of the pad body 20 from being bumped or damaged by the anchor casting. Furthermore, the anti-slip plate 50 is detachable, which facilitates the individual replacement of the anti-slip plate 50 after it is damaged, thereby reducing the cost of using the device.

[0042] Based on the above embodiments, further, the bottom end of the anti-slip plate 50 is provided with multiple sets of positioning posts 501 at intervals along its length direction, and the top end of the pad body 20 is provided with multiple sets of positioning holes 202 corresponding to the multiple sets of positioning posts 501, and the multiple sets of positioning posts 501 can be inserted into the multiple sets of positioning holes 202.

[0043] By setting multiple sets of positioning posts 501 and multiple sets of positioning holes 202, the horizontal sliding of the anti-slip plate 50 can be restricted, thereby improving the stability of the anti-slip plate 50 installed on the top surface of the pad body 20.

[0044] The specific implementation method of the above-mentioned large irregular-shaped casting heat treatment support frame is as follows:

[0045] Depending on the required heat treatment of the anchor casting, by rotating the shafts 301 on multiple sets of pad bodies 20, the rotation of the shafts 301 drives the two sets of worm gears 304 to rotate. The rotation of the two sets of worm gears 304 meshes with the two sets of worm wheels 303, driving the two sets of worm wheels 303 to rotate in opposite directions. The opposite rotation of the two sets of worm wheels 303 drives the two sets of gears 302 to rotate in opposite directions. The opposite rotation of the two sets of gears 302 meshes with the two sets of racks 305, thereby driving the pad body 20 to move along the length of the bearing platform 10. When the rotation of the shafts 301 is stopped, the two sets of worm gears 304 stop rotating. At this time, the two sets of worm gears 304 mesh with the two sets of worm wheels 303 to fix the gears 302, thereby fixing the pad body 20. The movement and fixing of the pad body 20 are convenient, and the position of the pad body 20 is easy to adjust, thus facilitating the bearing of different anchor castings and improving the practicality of the device.

[0046] Furthermore, by rotating the bidirectional screw 401, the bidirectional screw 401 and the two sets of baffles 403 are threaded together and driven to move closer to each other. The movement of the two sets of baffles 403 closer to each other can open the opening at the end of the T-shaped slide groove 101, thereby facilitating the T-shaped slider 201 to slide out of or into the T-shaped slide groove 101. This makes it easy to disassemble or add the pad body 20 as needed, further improving the practicality of the device.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
