Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A quick-change heat treatment multi-purpose furnace tooling fixture includes a heat treatment furnace 1, a support frame 2 fixedly connected inside the heat treatment furnace 1, a sliding frame 3 slidably connected to the top of the support frame 2, a plurality of support components 4 fixedly connected to the top of the sliding frame 3, and clamping components 5 snapped into the interior of each of the plurality of support components 4.

[0029] The clamping assembly 5 includes a snap-fit ​​plate 501. Two fixing blocks 502 are fixedly connected to the top of the snap-fit ​​plate 501. The interior of each fixing block 502 is threaded with a spiral rod 503. The opposite sides of each spiral rod 503 are rotatably connected to a mounting block 504. The opposite sides of each mounting block 504 are snapped with a clamping mold 505. The top of each mounting block 504 is snapped with a cover 506.

[0030] In this embodiment: A heat treatment furnace 1, the core processing equipment, provides the necessary temperature and atmosphere for workpiece heat treatment. It serves as the basic carrier for the installation of tooling fixtures and workpiece processing. A support frame 2, installed inside the heat treatment furnace 1, primarily supports the sliding frame 3, providing a stable sliding track foundation and ensuring the smoothness of the sliding frame 3 during movement within the furnace. The sliding frame 3 is connected to the top of the support frame 2 and is slidable. Multiple support components 4 are fixed at the top, enabling the support components 4 and the clamped workpiece to enter and exit the heat treatment furnace 1, facilitating workpiece loading, unloading, and transfer. The support components 4, containing multiple sub-components, are used to support and fix the clamping components 5, ensuring the stability of the clamping components 5 during heat treatment. A snap-fit ​​plate 501, the base plate of the clamping components 5, snaps into the mounting frame 401 at the bottom and a fixing block 502 is fixed at the top, providing an installation foundation for other clamping components 5 and connecting the clamping components 5 to the support components 4. The fixing block 502 is used to fix the clamping components 5 to the support components 4. The top of the snap-fit ​​plate 501 has an internally threaded connection to a spiral rod 503, providing mounting support for the spiral rod 503, limiting its movement direction, and ensuring stable rotation adjustment. The spiral rod 503 is threaded through a fixing block 502, with one end rotatably connected to a mounting block 504. Rotation of the mounting block 504 allows it to move left and right, thereby adjusting the spacing of the clamping mold 505 to accommodate workpieces of different sizes. The mounting block 504 is rotatably connected to the spiral rod 503, and one side snaps onto the clamping mold. 505, the top snap-fit ​​cover 506 can move with the screw rod 503, driving the clamping mold 505 to clamp or release the workpiece, and at the same time providing a mounting position for the cover 506. By setting the clamping mold 505, it is snapped on the opposite side of the mounting block 504 and directly contacts the workpiece. The adaptive structure is designed according to the shape of the workpiece to achieve stable clamping of the workpiece and prevent the workpiece from shifting during heat treatment. By setting the cover 506, it is snapped on the top of the mounting block 504 to limit the clamping mold 505 on the inner wall of the mounting block 504.

[0031] Specifically, such as Figure 3 As shown, the support component 4 includes a mounting frame 401, the bottom of which is fixedly connected to the top of the sliding frame 3, and a snap-fit ​​plate 501 snaps into the inner wall of the mounting frame 401.

[0032] Specifically, such as Figure 3 As shown, the inner wall of the mounting frame 401 has alignment grooves 402 on the left and right sides, and alignment blocks 403 are snapped into the inner walls of the two alignment grooves 402. The two alignment blocks 403 are fixedly connected to the left and right sides of the snap-fit ​​plate 501, respectively.

[0033] Specifically, such as Figure 3 As shown, the inner wall of the mounting frame 401 is threadedly connected to a threaded rod 404, and the top of the threaded rod 404 is rotatably connected to a top block 405.

[0034] In this embodiment: by setting an installation frame 401, the main frame of the support component 4 is fixed at the bottom to the sliding frame 3, and the inner wall is engaged with the snap-fit ​​plate 501 of the clamping component 5, providing installation and positioning space for the clamping component 5. By setting an alignment groove 402 and an alignment block 403, the inner walls of the alignment block 403 and the alignment groove 402 are spliced ​​together to facilitate the snap-fit ​​plate 501 to engage with the inner wall of the installation frame 401. By setting a threaded rod 404, it is threadedly connected to the inner wall of the installation frame 401, and the top is rotatably connected to the top block 405. By rotating the threaded rod 404, the height of the top block 405 can be adjusted, thereby pushing out the snap-fit ​​plate 501 to facilitate the disassembly of the snap-fit ​​plate 501 from the inner wall of the installation frame 401.

[0035] Specifically, such as Figure 3 As shown, a protective plate 6 is fixedly connected to the top of the top block 405, and a storage groove 7 is provided at the bottom of the inner wall of the mounting frame 401 to cooperate with the top block 405 and the protective plate 6.

[0036] Specifically, such as Figure 2 As shown, the top of the snap-fit ​​plate 501 is provided with a sliding groove 8, and the bottom of the two mounting blocks 504 are fixedly connected with sliding blocks 9 that cooperate with the sliding groove 8.

[0037] In this embodiment: by setting a protective plate 6, which is fixed to the top of the top block 405, when it comes into contact with the snap-fit ​​plate 501, it can prevent the top block 405 from directly rubbing against the snap-fit ​​plate 501 and causing wear, while enhancing the contact stability between the top block 405 and the snap-fit ​​plate 501. By setting a storage groove 7, which is opened at the bottom of the inner wall of the mounting frame 401, it is used to store the top block 405 and the protective plate 6. When it is not necessary to press the snap-fit ​​plate 501, the top block 405 and the protective plate 6 can be lowered and stored in the groove without affecting the loading and unloading of the snap-fit ​​plate 501. By setting a sliding block 9 and a sliding groove 8, the inner walls of the sliding block 9 and the sliding groove 8 are movably connected, and the sliding block 9 slides in the sliding groove 8 as the mounting block 504 moves, helping the mounting block 504 maintain a stable moving trajectory.

[0038] Specifically, such as Figure 5 As shown, a support leg 10 is fixedly connected to the bottom of the heat treatment furnace 1, and an anti-slip plate 11 is fixedly connected to the bottom of the support leg 10.

[0039] Specifically, such as Figure 2 As shown, knobs 12 are fixedly connected to opposite sides of the two screw rods 503, and several protrusions 13 are fixedly connected to the surface of each knob 12.

[0040] In this embodiment: by setting support legs 10, the heat treatment furnace 1 can be supported; by setting anti-slip plates 11, the positional deviation of support legs 10 can be reduced; by setting knobs 12, the user can easily adjust the screw rod 503; by setting protrusions 13, which are fixed on the surface of knobs 12, the friction of the knob surface is increased, and the operator is less likely to slip when turning knobs 12, thus improving the convenience and stability of operation.

[0041] Specifically, such as Figure 1 As shown, the top of the sliding frame 3 is provided with a pull-out hole 14, and a protective pad 15 is fixedly connected to the inner wall of the pull-out hole 14.

[0042] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, the top of the support frame 2 is provided with an auxiliary groove 16, and the bottom of the sliding frame 3 is fixedly connected with an auxiliary block 17 that works in conjunction with the auxiliary groove 16.

[0043] In this embodiment: By setting a pull-out hole 14, which is opened on the top of the sliding frame 3, and fixing a protective pad 15 on the inner wall, tools can be inserted, making it convenient for operators to pull the sliding frame 3 in and out of the heat treatment furnace 1. The protective pad 15 can prevent the tool from being damaged by friction with the inner wall of the pull-out hole 14. By setting the protective pad 15 and fixing it to the inner wall of the pull-out hole 14, the direct friction between the tool and the hole wall when it is inserted into the pull-out hole 14 is reduced, protecting the pull-out hole 14 and the tool. At the same time, it enhances the fit between the tool and the pull-out hole 14, making the sliding frame 3 more stable when pulled. By setting an auxiliary groove 16 and an auxiliary block 17, the inner walls of the auxiliary block 17 and the auxiliary groove 16 are movably connected, which helps the sliding frame 3 to maintain stable sliding and prevents the sliding frame 3 from deviating or shaking when sliding.

[0044] Working principle: First, the initial assembly of the tooling fixture and workpiece clamping need to be completed: First, align the sliding frame 3 with the auxiliary groove 16 on the top of the internal support frame 2 of the heat treatment furnace 1 via the auxiliary block 17 at the bottom, so that the sliding frame 3 is placed stably on the support frame 2. Next, align the snap-fit ​​plate 501 of the clamping assembly 5 with the mounting frame 401 of the support assembly 4. Use the alignment blocks 403 on both sides of the snap-fit ​​plate 501 to snap into the alignment grooves 402 on the inner wall of the mounting frame 401 to achieve precise positioning of the clamping assembly 5 and the support assembly 4. Then, rotate the threaded rod 404 on the inner wall of the mounting frame 401 to drive... The top block 405 and the top protective plate 6 move upwards until the protective plate 6 is tightly fitted to the bottom of the snap-fit ​​plate 501, thus firmly fixing the snap-fit ​​plate 501 inside the mounting frame 401. After fixing the clamping assembly 5, according to the size of the workpiece to be processed, rotate the knob 12 on the outside of the screw rod 503. Through the threaded engagement between the screw rod 503 and the fixing block 502, the mounting block 504 moves horizontally along the sliding groove 8 on the top of the snap-fit ​​plate 501, adjusting the distance between the two mounting blocks 504. Then, the clamping mold 505, which is adapted to the shape of the workpiece, is snapped onto the opposite side of the two mounting blocks 504. Place the workpiece between the two clamping molds 505, and continue to rotate the knob 12 to clamp the workpiece with the clamping molds 505. Finally, snap the cover 506 onto the top of the mounting block 504 to limit the clamping molds 505 and prevent them from shifting during heat treatment. After the workpiece is clamped, insert the tool through the pull hole 14 at the top of the sliding frame 3 and push the sliding frame 3 to slide along the auxiliary groove 16 of the support frame 2. Send the sliding frame 3 and the tooling fixture with the workpiece clamped as a whole into the heat treatment furnace 1. Close the furnace door to start the heat treatment operation. When it is necessary to change the mold to adapt to different tools... When replacing a workpiece, first pull the sliding frame 3 out of the heat treatment furnace 1, remove the cover 506, turn the knob 12 in the opposite direction to release the workpiece from the clamping mold 505 and remove the old mold. After replacing the new clamping mold 505, repeat the above clamping steps. If the entire clamping assembly 5 needs to be replaced, simply turn the threaded rod 404 in the opposite direction to lower the top block 405 and the protective plate 6 into the storage groove 7 at the bottom of the mounting frame 401. Then the snap plate 501 can be removed from the mounting frame 401 and the new clamping assembly 5 can be replaced. The entire mold replacement process does not require disassembling the bolts, which greatly shortens the replacement time and reduces the workload of the user.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
