Description

Technical Field

[0001] This utility model relates to the field of tool polishing technology, specifically a tool for polishing the cutting edge of a cemented carbide tool. Background Technology

[0002] Carbide cutting tools are tools that use carbide as the cutting part. Due to their high hardness, wear resistance, high strength, and heat resistance, they are widely used in the machining field. The cutting performance of carbide cutting tools directly determines the machining efficiency, machining quality, and machining cost. The quality of the cutting edge is one of the key factors affecting the cutting performance. During the production process of carbide cutting tools, polishing equipment is used to grind the cutting edge. Current polishing equipment mainly uses a fixture to limit the tool, and then the grinding tool grinds the cutting edge. During the grinding process, coolant is sprayed onto the grinding area, and the debris and wastewater flow into a collection box. The collection box filters the debris through a filter plate. However, most filter plates move back and forth in one direction. This unidirectional reciprocating movement easily leads to excessive accumulation of abrasive debris on the surface of the filter plate, forming a filter cake that blocks the filter holes, thereby reducing the subsequent filtration efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a polishing device for the cutting edge of cemented carbide cutting tools to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cemented carbide cutting edge polishing device, comprising a base, a clamp fixedly connected to the top of the base, a support frame connected to the outside of the base, an air pump provided on the front of the support frame, a grinding plate provided on the base, a clamp slidably connected inside the base, a sliding groove provided on the front of the base, a reciprocating structure slidably connected within the sliding groove, the reciprocating structure being connected to a filter plate, a sleeve plate connected to the outside of the base, a cam rotatably connected within the sleeve plate, an auxiliary structure provided within the filter plate, the auxiliary structure being connected to the front of the base, a limit post rotatably connected within the auxiliary structure, the reciprocating structure including a moving plate, a fixed plate fixedly connected to one side of the moving plate, and a telescopic device fixedly connected to one side of the fixed plate.

[0005] As a further preferred embodiment of this technical solution, the base is provided with a drain pipe on the front side, one end of the air pump is connected to the grinding plate, one end of the telescopic device is connected to the filter plate, and the movable plate is slidably connected in the groove.

[0006] As a further preferred embodiment of this technical solution, the auxiliary structure includes a concave plate, a support plate, and a gear. The support plate is fixedly connected to the front of the base, and a cross plate is fixedly connected to one side of the support plate. The cross plate is slidably connected inside the filter plate.

[0007] As a further preferred embodiment of this technical solution, the limiting post is rotatably connected inside the concave plate, the gear is fixedly connected outside the limiting post, and a toothed plate is slidably connected inside the concave plate.

[0008] As a further preferred embodiment of this technical solution, the toothed plate meshes with the gear, a diagonal rod is fixedly connected to one side of the support plate, a fixed sleeve is rotatably connected to the back of the toothed plate, and the fixed sleeve is slidably connected to the outside of the diagonal rod.

[0009] As a further preferred embodiment of this technical solution, a protrusion is connected to the outside of the limiting post, and a groove is opened inside the cam, with the protrusion slidably connected in the groove.

[0010] This utility model provides a polishing device for the cutting edge of cemented carbide cutting tools, which has the following beneficial effects:

[0011] (1) This utility model sets up a reciprocating structure, a sleeve plate, a cam and a filter plate. The filter plate is pushed or pulled by the telescopic device, and the filter plate will move back and forth in the base. The gear will drive the limiting post to rotate in the concave plate. When the limiting post moves, the protrusion on the surface will move in the groove. Then the cam will rotate in the sleeve plate with the limiting post as the center. When the cam rotates, it will contact the surface of the filter plate in turn. The polishing device realizes the function of the filter plate moving back and forth in the horizontal direction on the base through the cooperation between the reciprocating structure, the cam and the limiting post. The reciprocating motion mechanism provides a power source to drive the filter plate to move left and right periodically, avoiding the phenomenon of debris accumulation and blockage of the cam during the filtration process, thereby improving the subsequent filtration efficiency.

[0012] (2) By setting an auxiliary structure, the concave plate moves with the filter plate, the fixed sleeve moves on the surface of the inclined rod, and the toothed plate slides in the concave plate with the movement of the fixed sleeve. Since the toothed plate meshes with the gear, the gear drives the limiting column to rotate in the concave plate, so that the cam can rotate with the movement of the filter plate. This rotational motion is transmitted to the limiting column assembly through the transmission shaft, so that it completes the rotational motion in the limiting groove of the concave plate, realizing the synchronous and coordinated motion of the filter plate movement and the cam rotational motion. The system constructs a precise motion coupling relationship through a multi-level mechanical transmission chain to ensure that each component has a definite motion trajectory and phase relationship.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a carbide cutting edge polishing device includes a base 1, a clamp 2 fixedly connected to the top of the base 1, a support frame 3 connected to the outside of the base 1, an air pump 4 provided on the front of the support frame 3, a grinding plate 5 provided on the base 1, a clamp 2 slidably connected inside the base 1, a groove 11 opened on the front of the base 1, a reciprocating structure 7 slidably connected in the groove 11, the reciprocating structure 7 being connected to a filter plate 12, a sleeve plate 9 connected to the outside of the base 1, a cam 10 rotatably connected inside the sleeve plate 9, an auxiliary structure 8 provided inside the filter plate 12, the auxiliary structure 8 being connected to the front of the base 1, a limit post 13 rotatably connected inside the auxiliary structure 8, the reciprocating structure 7 including a moving plate 701, a fixed plate 702 fixedly connected to one side of the moving plate 701, and a telescopic device 703 fixedly connected to one side of the fixed plate 702.

[0020] like Figure 1 and Figure 3As shown, the base 1 has a drain pipe 6 on its front side, one end of the air pump 4 is connected to the grinding plate 5, one end of the telescopic device 703 is connected to the filter plate 12, the moving plate 701 is slidably connected in the slide groove 11, the auxiliary structure 8 includes a concave plate 801, a support plate 802 and a gear 807, the support plate 802 is fixedly connected to the front side of the base 1, a cross plate 803 is fixedly connected to one side of the support plate 802, the cross plate 803 is slidably connected in the filter plate 12, the limiting post 13 is rotatably connected in the concave plate 801, the gear 807 is fixedly connected to the outside of the limiting post 13, a toothed plate 805 is slidably connected in the concave plate 801, the toothed plate 805 meshes with the gear 807, a diagonal rod 804 is fixedly connected to one side of the support plate 802, a fixing sleeve 806 is rotatably connected to the back of the toothed plate 805, and the fixing sleeve 806 is slidably connected to the outside of the diagonal rod 804;

[0021] By setting the slide groove 11, when the filter plate 12 is affected by the pushing or pulling force, the moving plate 701 will slide in the slide groove 11, so that the slide groove 11 plays a certain guiding role in the movement of the moving plate 701, and avoids the phenomenon of the expansion joint 703 being bumped when the filter plate 12 moves.

[0022] like Figure 4 As shown, a protrusion 14 is connected to the outside of the limiting post 13, and a groove 15 is opened in the cam 10, with the protrusion 14 slidably connected in the groove 15.

[0023] By setting the protrusion 14 and the groove 15, when the limiting post 13 is affected by the pushing or pulling force, the protrusion 14 will slide in the groove 15, so that the protrusion 14 and the groove 15 play a certain auxiliary role for the cam 10, so that the cam 10 can rotate with the limiting post 13, and avoid the phenomenon of jamming when the limiting post 13 slides in the cam 10.

[0024] This utility model provides a polishing device for the cutting edge of cemented carbide cutting tools, the specific working principle of which is as follows:

[0025] When the polishing device is grinding the tool, it can be clamped by the clamp 2. Then the grinding plate 5 is adjusted by the air pump 4 to grind the tool in the clamp 2.

When the limiting post 13 moves, the protrusion 14 on its surface will move within the groove 15. Then the cam 10 will rotate within the sleeve 9 with the limiting post 13 as the center. When the cam 10 rotates, it will contact the surface of the filter plate 12 in sequence.
