Description

Technical Field

[0001] This utility model relates to the field of graphite heater technology, and in particular to a graphite heater mold that focuses on high precision. Background Technology

[0002] Graphite heaters are widely used in industrial fields due to their excellent thermal conductivity and high temperature resistance. Their processing requires special cutting molds to achieve precise positioning and efficient processing of parts of different specifications.

[0003] Existing technology, such as the graphite heater processing mold disclosed in announcement number CN215392926U, includes a base plate, a fixed plate, and a double clamping mechanism. The base plate has sliding groove-type fixed plates on both sides, and a servo motor drives the clamping plates to move. This, combined with dual electric telescopic rods, controls the lifting of the baffle and the displacement of the limit frame, achieving precise positioning of workpieces of various sizes and chip protection, thus improving processing efficiency and safety.

[0004] However, this technical solution has the following problems in practical use:

[0005] The limiting frame is rigidly connected to the output end of the second electric telescopic rod, achieving synchronous linkage through electric drive. Together with the clamping plate, it forms a bidirectional positioning mechanism, ensuring accurate positioning and stable clamping of the workpiece. However, because the limiting frame adopts a rigid welded integrated structure, it cannot adapt to irregularly shaped workpiece contours, resulting in localized gaps on the clamping contact surface. Under machining vibration conditions, this can easily lead to stress concentration, directly affecting clamping stability and machining accuracy. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the existing limit frame adopts a rigid welded integrated structure, which makes it unable to adapt to the contour of irregular workpieces and has local gaps in the clamping contact surface. Therefore, this invention proposes a graphite heater mold that focuses on high precision.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-precision graphite heater mold includes a pair of concave seats, on which a pair of movable plates are horizontally slidably connected. T-shaped grooves are formed on the opposite sidewalls of the two movable plates. T-shaped blocks are horizontally slidably inserted into the T-shaped grooves. Clamping plates are fixedly connected to the T-shaped blocks. Limiting rods are threadedly connected to the movable plates, and the limiting rods are in contact with the T-shaped blocks.

[0009] Preferably, a pair of screws are threaded onto the concave seat, and the end of the screws near the movable plate is rotatably connected to the vertical sidewall of the movable plate.

[0010] Preferably, a screw block is fixedly connected to the other end of the screw, and a groove is provided on the concave seat to facilitate the horizontal sliding of the movable plate.

[0011] Preferably, a base is provided below the concave seat, a top frame is provided above the base, four support rods are fixedly connected to the top of the base, a sleeve plate is fixedly connected to the top of the support rods, the top frame and the sleeve plate are vertically slidably inserted, and the top frame and the sleeve plate are threadedly connected by the same fixing bolt.

[0012] Preferably, the top of the sleeve plate is provided with an installation groove to facilitate the vertical sliding insertion of the top frame, and the sleeve plate is provided with a plurality of installation holes at equal intervals to facilitate the threaded connection of the fixing bolts.

[0013] Preferably, each of the two concave seats has a vertical plate on its opposite side. A rotating shaft is rotatably connected to the vertical side wall of the vertical plate near the concave seat. The end of the rotating shaft away from the vertical plate is fixedly connected to the concave seat. A motor for driving the rotating shaft to rotate is fixedly connected to the vertical plate.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention utilizes components such as T-blocks to enable quick clamping plate replacement through the sliding engagement of the T-blocks with the T-grooves on the moving plate. After loosening the limiting rod to release the lock, the clamping plate can be horizontally removed along the groove track. Reverse locking completes the adaptation. This design ensures that the clamping surface of the clamping plate precisely conforms to the contour of irregularly shaped workpieces, effectively eliminating clamping gaps, ensuring clamping stability during processing, and improving the overall applicability of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-3 A high-precision graphite heater mold includes a pair of concave seats 1, with a pair of movable plates 2 horizontally slidably connected to the concave seats 1. The pair of concave seats 1 and the horizontally sliding movable plates 2 form a symmetrical clamping system in the left-right and front-back directions, completing the clamping and fixing of the component. T-slots 36 are formed on the opposite sidewalls of the two movable plates 2, and T-blocks 34 are horizontally slidably inserted into the T-slots 36. The arrangement of the T-blocks 34 and the T-slots 36 facilitates the removal of the T-blocks 34 and clamping plates 3 together, enabling the replacement of the clamping plates 3 and ensuring a tight fit between the clamping plates 3 and the component to prevent shaking. A clamping plate 3 is fixedly connected to the T-block 34, and a limit rod 35 is threadedly connected to the movable plate 2, contacting the T-block 34. The limit rod 35 blocks the T-block 34, preventing horizontal displacement of the T-block 34 in the front-back direction, thus locking the T-block 34.

[0027] A pair of screws 31 are threaded onto the concave seat 1, and the end of the screw 31 near the moving plate 2 is rotatably connected to the vertical side wall of the moving plate 2.

[0028] The other end of the screw 31 is fixedly connected to a screw block 32, and the concave seat 1 is provided with a groove 33 to facilitate the horizontal sliding of the movable plate 2. The groove 33 is provided to ensure that the movable plate 2 can move stably back and forth horizontally along the axial direction of the screw 31.

[0029] A base 5 is provided below the concave seat 1, and a top frame 6 is provided above the base 5. Four support rods 61 are fixedly connected to the top of the base 5, and a sleeve plate 62 is fixedly connected to the top of the support rods 61. The top frame 6 and the sleeve plate 62 are vertically slidably inserted, and the top frame 6 and the sleeve plate 62 are threadedly connected by the same fixing bolt 64.

[0030] The top of the sleeve plate 62 has a mounting groove 65 for easy vertical sliding insertion of the top frame 6. The guide design of the mounting groove 65 ensures smooth and stable lifting of the top frame 6. Multiple mounting holes 63 are evenly spaced on the sleeve plate 62 for easy threaded connection of the fixing bolts 64. The mounting holes 63 facilitate fixing the top frame 6 after height adjustment. The height of the top frame 6 can be adjusted according to actual processing and production needs (such as component width, comfortable operating height for workers, etc.).

[0031] Two concave seats 1 are each provided with a vertical plate 4 on their opposite sides. A rotating shaft 41 is rotatably connected to the vertical side wall of the vertical plate 4 near the concave seat 1. The end of the rotating shaft 41 away from the vertical plate 4 is fixedly connected to the concave seat 1. A motor 42 for driving the rotating shaft 41 to rotate is fixedly connected to the vertical plate 4. After the clamping plate 3 clamps and fixes the part, the part or mold rotates stably according to the actual processing requirements under the drive of the motor 42.

[0032] In the prior art, both the lead screw and the servo motor are mounted on the top frame 6. The main function of the lead screw and the servo motor is to drive the two vertical plates 4 to move relative to each other or away from each other. After the vertical plates 4 move, the two concave seats 1 and the components or molds are pressed together. The working principle of the lead screw and the servo motor is based on the graphite heater processing mold disclosed in announcement number CN215392926U, which is prior art and will not be described in detail here.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] First, the graphite heater component to be processed is placed in the center of the pair of concave seats 1, and the lateral positioning is adjusted according to the component size. Using existing technology, the two vertical plates 4 are driven to move synchronously relative to each other until the two concave seats 1 components are pressed together, achieving horizontal positioning.

[0035] Subsequently, the operator rotates the screw blocks 32 at the ends of the screws 31 on both sides of the concave seat 1, and drives the moving plate 2 to slide horizontally back and forth along the slide groove 33 through the threaded engagement between the screws 31 and the concave seat 1; when the spacing between the two sets of moving plates 2 is appropriate and they are close to the width of the component, the clamping and fixing work of the component is completed.

[0036] Before clamping the component, when it is necessary to select a suitable clamping plate 3 according to the shape of the component, loosen the limiting rod 35 to release the lock on the T-shaped block 34, and push out the T-shaped block 34 and clamping plate 3 together along the T-shaped groove 36 of the moving plate 2. During installation, reverse the above operation to complete the replacement of clamping plate 3, ensuring that clamping plate 3 can fit tightly with the component, thereby ensuring the stability and actual effect of clamping and fixing.

[0037] When the height of the top frame 6 needs to be adjusted according to the width of the actual component, loosen the fixing bolts 64 on the sleeve plate 62, slide the top frame 6 up and down along the mounting groove 65 to the predetermined height, select one of the corresponding holes 63 through the multiple mounting holes 63, tighten the fixing bolts 64 by threading to complete the re-locking, thereby completing the adjustment of the height of the top frame 6, so that the clamped and fixed component will not be disengaged from the base 5 when rotating, thus affecting the rotation effect.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
