Description

Technical Field

[0001] The utility model belongs to the technical field of cutter tools, and in particular relates to an L-shaped cutting tool bar assembly. Background Art

[0002] Graphite products are a kind of industrial materials with wide applications. They are widely used mainly due to their excellent physical and chemical properties. They include graphite electrodes, refractory materials, high-purity graphite, graphite products, graphite crucibles, graphite targets, etc.

[0003] Among them, graphite products are a kind of mold made of graphite as the main raw material. When producing these graphite products, CNC machine tools are needed to process them. First, the graphite products are clamped and fixed with a three-jaw chuck, while driving the graphite products to rotate. Then, the cutting tool rod is fixed by the four-station tool holder, and finally, the middle support plate is pushed, and the graphite products can be processed with the cutting tool rod.

[0004] When processing large-volume graphite products, in order to prevent the center support plate and the graphite products from colliding with each other, thereby affecting the processing of the graphite products, a large distance will appear between the cutting tool bar and the graphite product. However, the existing cutting tool bar has a limited cutting distance and cannot process large-volume graphite products in all directions, which easily affects the processing progress. For this reason, we proposed an L-shaped cutting tool bar assembly to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide an L-shaped cutting tool bar assembly to solve the problems existing in the background technology.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] The L-shaped cutting knife rod assembly includes a cutting knife seat, a pressure plate groove is provided in the middle of the front end of the cutting knife seat, a completely penetrating fixing groove is provided at the left end of the cutting knife seat, and the fixing groove and the pressure plate groove are perpendicular to each other, a cutting knife plate is clamped inside the fixing groove, diamond blades are provided on the upper sides of the left and right ends of the cutting knife plate, and a threaded hole is provided in the middle of the front side of the upper end of the cutting knife seat.

[0008] Furthermore, a completely penetrating connecting hole is provided at the left end of the cutting knife seat, and the connecting hole is communicated with the rear side of the pressing plate groove.

[0009] Furthermore, functional grooves are symmetrically opened on the left and right sides of the cutting knife plate surface, the two diamond blades are respectively clamped at the openings of the two functional grooves, and the cutting knife plate surface is symmetrically opened with expansion holes respectively located in the middle of the two functional grooves.

[0010] Furthermore, two holes are symmetrically formed on the surface of the cutting knife plate, and the two holes are respectively connected to the sides adjacent to the two functional grooves.

[0011] Furthermore, the upper end of the diamond blade is arranged as a plane, the lower end of the diamond blade is arranged as a concave surface, and the lower wall of the functional groove is arranged with a convex surface matching the concave surface of the diamond blade.

[0012] Furthermore, the four corners of the upper end of the diamond blade protrude in all directions.

[0013] Furthermore, the surface of the cutting knife plate is symmetrically provided with protective holes on both sides, and the two protective holes are respectively wrapped around the edge positions of one end opposite to the two diamond blades.

[0014] The beneficial effects of the utility model are:

[0015] 1) According to the different specifications of the graphite products being processed, the installation position of the four-station tool holder for the L-shaped cutting tool rod assembly can be flexibly adjusted to achieve the processing effect required by the staff.

[0016] 2) By fixing the cutting tool holder handle at different positions of the four-station tool holder, the distance between the middle support plate and the graphite product to be processed can be adjusted to prevent the middle support plate from touching the graphite product, thereby affecting the processing of the graphite product.

[0017] 3) By turning the bolt, the cutter plate can be moved in the fixed groove, so as to flexibly adjust the processing position of the diamond blade.

[0018] 4) By dividing the L-shaped cutting tool bar assembly into three parts, namely, the cutting tool seat, the cutting tool plate and the diamond blade, when a single part is damaged, the staff can only replace the damaged part without completely replacing the entire cutting tool bar assembly. This not only makes it convenient for the staff to quickly assemble the L-shaped cutting tool bar assembly, but also reduces production costs.

[0019] 5) By setting the four corners of the diamond blade, the graphite product can be processed. When one corner cannot be processed, the staff can directly adjust the position of the diamond blade to continue processing the graphite product, reducing the replacement time of the staff and improving production efficiency.

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Embodiment 1:

[0030] like Figure 1-Figure 3 As shown, the L-shaped cutting tool rod assembly includes a cutting knife seat 100, a pressure plate groove 101 is opened in the middle of the front end of the cutting knife seat 100, a completely penetrating fixing groove 102 is opened at the left end of the cutting knife seat 100, and the fixing groove 102 and the pressure plate groove 101 are perpendicular to each other, a cutting knife plate 103 is clamped inside the fixing groove 102, diamond blades 104 are provided on the upper sides of the left and right ends of the cutting knife plate 103, and a threaded hole 105 is opened in the middle of the upper front side of the cutting knife seat 100.

[0031] The cutting knife seat 100 is divided into a seat head and a seat handle. The four-station tool holder is pressed against the seat handle by a long bolt to fix the entire L-shaped cutting knife rod assembly. The pressure plate groove 101 and the fixing groove 102 are both opened inside the seat head. The pressure plate groove 101 divides the seat head into two parts, and the upper and lower parts of the seat head can be opened or closed. When the upper and lower parts of the seat head are opened, the cutting knife plate 103 can be inserted into the fixing groove 102. After the bolts are screwed into the threaded holes 105, the upper and lower parts of the seat head can be closed, so that the fixing groove 102 clamps and fixes the cutting knife plate 103 to prevent the cutting knife plate 103 from moving and shaking, thereby affecting the processing of graphite products by the diamond blade 104. Since the processed products are graphite products, various problems will occur during the processing of general processing blades, so diamond blades 104 made of special materials are required to process graphite products.

[0032] Before processing graphite products: the three-jaw chuck of the CNC machine tool can fix the graphite products to be processed, and can also drive the graphite products to rotate, which is convenient for subsequent processing of graphite products. The four-station tool holder can fix the L-shaped cutting tool bar assembly. When the middle support plate moves close to the graphite product, the L-shaped cutting tool bar assembly can process the graphite product.

[0033] When processing small-volume graphite products: the cutter holder handle of the cutter holder 100 is parallel to the graphite product to be processed, and the staff can release the extrusion of the pressure plate groove 101 by screwing the bolts, so that the cutter blade 103 can slide inside the fixed groove 102. When the cutter blade 103 slides to a suitable position, the bolts are tightened to press the cutter blade 103, and the diamond blade 104 is aligned with the graphite product to be processed, so that the graphite product can be processed;

[0034] When processing large-volume graphite products: the cutter head of the cutter seat 100 points to the graphite product to be processed, the bolt is turned to release the extrusion of the pressure plate groove 101, the cutter plate 103 is slid, and the diamond blade 104 is moved to the outside of the graphite product. After tightening the bolt, the outside of the graphite product can be processed.

[0035] In the above processing steps, the graphite product is kept away from the middle support plate, which not only prevents the graphite product from being processed, but also allows the position of the diamond blade 104 to be adjusted to accommodate the processing of different positions of graphite products of different specifications.

[0036] In this embodiment, by turning the bolt, the pressure plate groove 101 can be loosened or tightened, thereby fixing or releasing the clamping of the cutting knife plate 103, thereby facilitating the cutting knife plate 103 to move inside the fixed groove 102, thereby adjusting the position of the diamond blade 104, and facilitating all-round processing of graphite products of different specifications.

[0037] Embodiment 2:

[0038] Based on the first embodiment, other structures on the L-shaped cutting tool bar assembly are further described. Figure 2-Figure 5 As shown, a completely penetrating connecting hole 200 is opened at the left end of the cutting knife seat 100, and the connecting hole 200 is communicated with the rear side of the pressing plate groove 101.

[0039] The cutting knife plate 103 has functional grooves 201 symmetrically formed on both sides thereof. The two diamond blades 104 are respectively engaged with the openings of the two functional grooves 201 . The cutting knife plate 103 has expansion holes 202 symmetrically formed on the surface thereof, which are respectively located in the middle of the two functional grooves 201 .

[0040] Two holes 203 are symmetrically formed on the surface of the cutting knife plate 103 , and the two holes 203 are respectively connected to the adjacent sides of the two functional grooves 201 .

[0041] The upper end of the diamond blade 104 is set to be a plane, the lower end of the diamond blade 104 is set to be a concave surface, and the lower wall of the functional groove 201 is set to be a convex surface matching the concave surface of the diamond blade 104.

[0042] The four corners of the upper end of the diamond blade 104 are all protruding toward the surroundings.

[0043] The cutting knife plate 103 has protective holes 204 symmetrically formed on both sides thereof, and the two protective holes 204 are respectively wrapped around the edge positions of the opposite ends of the two diamond blades 104 .

[0044] In this embodiment, after loosening and tightening the bolts for a long time, the upper and lower sides of the pressure plate groove 101 will move repeatedly, causing fatigue of the material of the cutter seat head of the cutting knife seat 100, and then causing damage to the cutting knife seat 100. The connecting hole 200 can alleviate the fatigue strength of the material and extend the service life of the cutting knife seat 100.

[0045] The staff can insert a tool into the expansion hole 202 to open the functional groove 201. At this time, the diamond blade 104 can be inserted into the opening of the functional groove 201. Since the lower end of the diamond blade 104 is set as a concave surface and the lower wall of the functional groove 201 is set as a convex surface, the clamped diamond blade 104 can be made more secure.

[0046] The diamond blade 104 and the cutting blade plate 103 are separated from each other, which not only allows the staff to replace the diamond blade 104 separately after the diamond blade 104 is damaged, but also saves production costs.

[0047] Each time the diamond blade 104 is replaced, the functional slot 201 will open, and the hole 203 can share the tension when the functional slot 201 opens, thereby preventing the cutting knife plate 103 from being damaged.

[0048] The four corners of the upper end of the diamond blade 104 are all protruding in all directions, and these four corners can all be used to process graphite products. When one corner is damaged, the direction of the diamond blade 104 can be adjusted to indirectly extend the service life of the diamond blade 104 and save costs.

[0049] The protection hole 204 can wrap around the edge of the diamond blade 104 to prevent the edge of the diamond blade 104 from damaging the cutting blade plate 103 during processing, thereby affecting the processing of the graphite product.
