Description

Technical Field

[0002] Cemented carbide is a common alloy material. Cemented carbide has the advantages of heat resistance, wear resistance, corrosion resistance and high strength. Cemented carbide needs to be clamped by a fixture during the processing. When the existing fixture clamps the square plate-shaped cemented carbide, it needs to be manually adjusted to ensure that the processed end surface of the cemented carbide is in a horizontal state, and the size of the non-clamped part cannot be flexibly controlled, which makes it inconvenient to process cemented carbide.

[0003] According to the Chinese utility model publication number CN212122459U, a cemented carbide cutting and processing fixture is disclosed, which includes a box body, a bidirectional threaded rod is rotatably installed inside the box body, and the outer side of the bidirectional threaded rod is threadedly connected to two sliding rods, and the bottom end of the sliding rod is slidably installed on the bottom inner wall of the box body. In the utility model, the cemented carbide cutting and processing fixture described in the utility model, through the two worms, the rotation of the worms drives the two worm wheels to rotate, so that the two hollow frames above the worm wheels are close to each other or away from each other, so that the two clamping strips are close to each other or away from each other, and finally meet the clamping effect of the front and back of the cemented carbide. However, this setting requires manual adjustment to ensure that the processing end face of the cemented carbide is in a horizontal state, and the size of the non-clamping part cannot be flexibly controlled, which is not convenient for processing the cemented carbide. Therefore, in view of this problem, how to design a cemented carbide processing fixture has become a problem that we currently need to solve. Utility Model Content

[0013] 1. The utility model provides a ruler and a positioning plate, and ensures that the alloy is in a horizontal state by contacting the alloy with the positioning plate. The first adjusting screw can be rotated by turning the first turning handle, thereby causing the transmission member to rise.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Refer to the instruction manual Figure 1-3 ,like Figure 1As shown, a cemented carbide processing fixture of an embodiment of the utility model includes a fixture body 1, a limit member 2 is fixedly installed on one side of the fixture body 1, the top of the limit member 2 is rotatably connected with a first adjusting screw 3, the outer side of the first adjusting screw 3 is threadedly connected with a transmission member 4, the top of the first adjusting screw 3 is fixedly installed with a first handle 5, a position indicating member 6 is fixedly installed on one side of the fixture body 1, a ruler 7 is fixedly installed on the top of the transmission member 4, the ruler 7 is slidably connected to the inside of the position indicating member 6, a top plate 8 is fixedly installed on the top of the ruler 7, a positioning plate 9 is fixedly installed on one side of the top plate 8, the positioning plate 9 is slidably connected to one side of the fixture body 1, a movable clamp 10 is slidably connected to the top of the clamp body 1, and a first sliding block 11 is fixedly installed on the bottom of the movable clamp 10.

[0021] It should be noted that, when clamping the cemented carbide, the cemented carbide is placed on the top of the positioning plate 9. Since the positioning plate 9 is set horizontally, the top processing end surface of the square cemented carbide can be in a horizontal state, which is convenient for grinding and other operations, and avoids the phenomenon of grinding tilt caused by uneven clamping. At the same time, when the movable handle 14 is turned to drive the screw 12 to rotate, the first sliding block 11 will be prompted to slide, and then the movable clamp 10 will slide, so as to clamp and fix the cemented carbide. At the same time, the first adjusting screw 3 can be rotated by rotating the first rotating handle 5, so that the transmission member 4 can rise. At the same time, the ruler 7 slides inside the indicating member 6. The surface of the ruler 7 is engraved with scales. By observing the overlapping point of the ruler 7 and the indicating member 6, the height of the rising of the positioning plate 9 can be judged, and then the length of the cemented carbide clamping can be judged, so that the exposed length of the alloy is the required length, which is convenient for grasping the size of the cemented carbide and facilitating the processing of the cemented carbide.

[0022] Further, such as Figure 1 As shown, the first sliding block 11 is slidably connected to the inside of the clamp body 1, and a lead screw 12 is rotatably connected to the inside of the clamp body 1. The lead screw 12 and the first sliding block 11 are arranged in a threaded connection. A rotating cap 13 is fixedly installed at one end of the lead screw 12, and a movable handle 14 is slidably connected to the inside of the rotating cap 13. A base 15 is fixedly installed at the bottom of the clamp body 1. Figure 2 As shown, the interior of the positioning plate 9 is slidably connected to a second sliding block 16, the interior of the second sliding block 16 is threadedly connected to a second adjusting screw 17, the second adjusting screw 17 is rotatably connected to the interior of the positioning plate 9, a limiting rod 18 is fixedly installed inside the positioning plate 9, the second sliding block 16 is slidably connected to the outside of the limiting rod 18, a side baffle 19 is hinged on the top of the second sliding block 16, and a second turning handle 20 is fixedly installed on one end of the second adjusting screw 17.

[0023] It should be noted that, by flipping the side baffle 19 to a vertical state, the cemented carbide is placed on the inner side of the side baffle 19 and the positioning plate 9, and the second sliding block 16 is slid by rotating the second turning handle 20, so that the side baffle 19 slides to one side, and the cemented carbide is driven to slide by the side baffle 19, so that one side of the alloy protrudes from the fixture body 1, thereby controlling the distance between the top and the side of the cemented carbide, thereby facilitating the cutting of the cemented carbide, thereby further improving the convenience of cemented carbide processing.
