Description

Technical Field

[0001] This utility model relates to the technical field of cemented carbide processing, specifically to a restrictible cemented carbide processing clamping device. Background Technology

[0002] Cemented carbide refers to alloy materials made from hard compounds of refractory metals and binder metals through powder metallurgy. It has properties such as high hardness, high wear resistance, good strength and toughness, heat resistance and corrosion resistance. It is widely used in the machining of various cutting tools, such as turning tools, milling cutters, planing tools, drill bits, etc. During the production and machining of cemented carbide, clamping devices are needed to clamp and position the cemented carbide.

[0003] As disclosed in announcement number CN219113855U, a cemented carbide machining clamping device is described. This cemented carbide machining clamping device includes: a mounting box; a placement box fixedly installed in the middle of the top of the mounting box, with a mounting plate fixedly installed on one side of the placement box. This utility model provides a cemented carbide machining clamping device that uses two limiting devices to restrict the bottom one and two pieces of cemented carbide inside the unloading chamber. When the bottom piece of cemented carbide needs to fall, the limiting device disengages, allowing the bottom piece to fall. Then, the limiting device returns to the unloading chamber, and the top limiting device moves to the left, causing the top piece of cemented carbide to fall to the top of the bottom limiting device. The top limiting device then re-inserts into the bottom of the second piece of cemented carbide, restricting the top piece, ensuring that only one piece of cemented carbide falls at a time.

[0004] However, existing technologies have drawbacks such as the inconvenience of stably clamping cemented carbide of different sizes, the fact that the angle of cemented carbide is mostly fixed during processing, making it inconvenient to adjust the angle, and the fact that the temperature of cemented carbide is sometimes high during processing, making it inconvenient to quickly dissipate heat, which can easily cause burns when removing the part after processing. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a restrictive cemented carbide machining clamping device. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a restraintable cemented carbide machining clamping device, comprising a base, a support base, and a fixing clamp;

[0008] Also includes:

[0015] The movable plate and the fixed rod form an up-and-down sliding structure.

[0016] Preferably, the lower end of the movable plate is engaged with a protrusion for positioning, and the protrusions are evenly spaced at the bottom of the support plate.

[0017] Preferably, the upper end of the support base is threaded with connecting bolts on both the front and rear sides, and the inner side of the connecting bolts is rotatably connected with a fixing plate for clamping, the fixing plate forming a front and rear sliding structure at the upper end of the support base.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the restrictable cemented carbide processing clamping device can adjust the distance between the individual support seats on the left and right sides by moving the support seats on the support plate, thereby facilitating the bearing of cemented carbide of different sizes. Combined with the fixed clamping plate, the cemented carbide is stably clamped. The support plate can also rotate on the upper end of the base to adjust the processing angle of the cemented carbide during processing. Combined with the cooling fan, the cemented carbide being processed can be cooled by blowing air to prevent the temperature of the cemented carbide from being too high and burning the operator when unloading the material.

[0019] 1. It is equipped with a base and a support plate. The support plate rotates on the upper part of the base, which can drive the cemented carbide to rotate on the upper part of the base during processing, thereby facilitating the adjustment of the processing angle of the cemented carbide.

[0029] 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.

[0030] Please see Figures 1-6 .

[0031] To address the problems in existing technologies, such as the inconvenience of stably clamping cemented carbide of different sizes, the fixed angles during cemented carbide processing making angle adjustment difficult, and the high temperatures that cemented carbide sometimes experiences during processing making rapid heat dissipation difficult and causing burns when removing the workpiece after processing, this solution provides a restraint-type cemented carbide processing clamping device. The device comprises a base 1, a support seat 8, and a fixed clamping plate 14. A bearing plate 2 is rotatably connected to the upper end of the base 1, and support seats 8 are fitted to both the left and right sides of the bearing plate 2. The support seats 8 can move left and right on the bearing plate 2, and a movable plate 11 for limiting movement is provided at the lower end of the support seat 8. A circular cover 6 is fixedly connected to both the left and right sides of the bearing plate 2, and a cooling fan 7 is installed in the circular cover 6.

[0032] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a support plate 2 is provided above the base 1. First, according to the size of the cemented carbide to be processed, the auxiliary rod 15 fixed in the middle of the movable plate 11 is pulled upward. The auxiliary rod 15 drives the movable plate 11 to move upward. The movable plate 11 slides between itself and the fixed rod 9. The movable plate 11 compresses the spring 10, causing the spring 10 to undergo elastic deformation. The lower end of the movable plate 11 disengages from the protrusion 12, thereby releasing the limit between the support seat 8 and the support plate 2. Then, the support seat 8 is pulled to the left or right, and the support seat 8 slides left and right between itself and the limit bar 5. The support seat 8 moves in the middle of the support plate 2, which facilitates the adjustment of the spacing between the individual support seats 8 on the left and right sides of the support plate 2, making it convenient to process cemented carbide of different sizes. After the spacing is adjusted, the auxiliary rod 15 is released directly. At this time, the spring 10 returns to its elastic deformation, pushing the movable plate 11 to move downward and engage with the protrusion 12 at the corresponding position at the bottom of the support plate 2, thereby facilitating the fixation of the support seat 8.

[0033] Then place the cemented carbide to be processed on the upper end of the support 8, such as... Figure 2 and Figure 3As shown, by rotating the connecting bolts 13 threaded to the front and rear sides of the upper end of the support base 8, the connecting bolts 13 and the fixed clamping plate 14 rotate, thereby pushing the fixed clamping plate 14 to slide on the upper end of the support base 8, so that the fixed clamping plate 14 stably clamps the cemented carbide. After clamping, the cemented carbide is subjected to corresponding processing operations. During the processing, the bearing plate 2 can also be rotated, and the bearing plate 2 and the fixed sleeve 3 can rotate on the upper end of the base 1, which can drive the cemented carbide to rotate, thereby adjusting the processing angle of the cemented carbide. After the adjustment is completed, the fixed bolt 4 is rotated to limit the distance between the fixed sleeve 3 and the base 1, fixing the bearing plate 2 on the upper end of the base 1. After the processing is completed, the cooling fan 7 in the round cover 6 can be turned on to blow air and cool down the cemented carbide to prevent burns during material handling.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
