Description

Technical Field

[0001] The invention belongs to the technical field of machine tool pressure treatment and knurling, and specifically relates to a combined machine tool for pressure treatment of metal parts and a use method thereof. Background Art

[0002] Knurling is a mechanical process used to roll patterns onto the surface of metal products, primarily for anti-slip and aesthetic purposes. The knurling process can produce complex patterns on the surface of a part, which can be composed of straight lines, angles, or interlocking designs, and are intended to improve the durability, aesthetics, and grip of the part.

[0003] The knurling process is usually performed on a lathe, using a knurling tool to roll or cut the surface of the part to create a pattern. These patterns can be straight ridges or spiral arrangements, unlike the more traditional criss-cross design.

[0004] Citing a Chinese patent, the application number is: 2016102230435, which discloses a knurling alignment device for a shaft, including a pair of oppositely arranged positive knife arms and reverse knife arms and a knife arm support slide plate for connecting the positive knife arms and the reverse knife arms, one end of the positive knife arm and the reverse knife arm are respectively provided with a knurling wheel, and the other end of the positive knife arm and the reverse knife arm are arranged on the knife arm support slide plate, characterized in that: the knurling alignment device also includes a bracket, a positioning mandrel and a spring sheet connecting the knife arm support slide plate and the processing machine tool, the knife arm support slide plate and the bracket are respectively provided with through holes, the positioning mandrel is penetrated in the through holes of the support slide plate and the bracket, the spring sheet is located on both sides of the bracket, one end of the spring sheet is fixed on the bracket, and the other end is against the side of the knife arm bracket slide plate, and the two spring sheets limit the rotation of the knife arm support slide plate centered on the positioning mandrel. The present invention provides a knurling alignment device for a shaft, which can achieve self-centering and improve the processing efficiency and precision of the shaft spline.

[0005] However, the above-mentioned existing machine tools are difficult to achieve operations such as pressurizing the surface of parts and knurling, because most of the tools can only grind and cut the parts, and it is difficult to knurl cylindrical parts, and the entire base needs to be replaced. This is because the knurled part is different from the connecting seat at the tail of the machine tool tool, so the entire base needs to be replaced before the knurling operation can be performed, which is relatively complicated. At the same time, since the knurling blade is mostly set with a unidirectional tilt, the knurling on the surface of the part after the operation is also tilted. At this time, the part needs to be removed and installed in reverse, and the knurling step needs to be performed again to complete the knurling operation, which is relatively inefficient. For this reason, we propose a combined machine tool for pressurizing metal parts and a method for using it. Summary of the invention

[0024] S1: The pressurized knurling assembly is in an open state, and the stepper motor is operated, so that the stepper motor drives the output shaft and the angle rotation shaft to rotate, and the angle rotation shaft then drives the L-shaped connecting plate, the second knurled arc block, and the first knurled arc block to rotate, so that the first knurled arc block, the third knurled arc block, and the third knurled arc block are in an open state;

[0025] S2: According to the use requirements, the x-axis lateral moving part and the pressure treatment knurling assembly are moved so that the pressure treatment knurling assembly is in the substitute knurling operation position, and then the knurling height adjustment rod is operated so that the knurling height adjustment rod drives the third knurling arc block and the bottom parts of the third knurling arc block to move up and down so that the main body of the metal component is located on one side of the second knurling arc block;

[0026] S3: Adjust the pressurized knurling assembly to a closed state, operate the stepper motor, so that the stepper motor drives the output shaft and the angle rotation shaft to rotate, and the angle rotation shaft then drives the L-shaped connecting plate, the second knurled arc block, and the first knurled arc block to rotate, so that the first knurled arc block, the third knurled arc block, and the third knurled arc block are in a circular structure, at which time the first knurled arc block, the third knurled arc block, and the third knurled arc block wrap the metal component body, and the second knurled piece and the first knurled piece are located at the side wall position of the metal component body;

[0027] S4: operating the knurled electromagnetic suction plates so that the knurled electromagnetic suction plates are connected to each other and the rotating shaft is limited by the knurling. When the knurled electromagnetic suction plates are in operation, the two knurled electromagnetic suction plates can adjust their angles by themselves so that the knurled electromagnetic suction plates are always in a parallel state.

[0028] S5: The metal component clamping seat is operated, and the second knurling member and the first knurling member perform knurling operation on the main body of the metal component. At the same time, the x-axis lateral moving member can be operated, so that the x-axis lateral moving member can drive the pressurized knurling assembly to move horizontally, thereby making the knurling operation of the main body of the metal component more continuous;

[0029] S6: When the second knurling member and the first knurling member perform knurling operation on the main body of the metal component, the third knurling arc block, the second knurling arc block and the first knurling arc block can form a wrapping ring to reduce the splashing of debris generated by the knurling operation;

[0030] S7: After the surface of the metal component body is processed to form a knurled pattern, the pressurized knurling assembly can be adjusted from a closed state to an open state, and the metal component body can be removed normally, and the knurling operation is completed.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The present invention adopts a bidirectional movement method to pressurize the metal parts so that the metal parts have a knurling effect. At the same time, it will not affect the original tool operation, so that the machine tool has multiple effects and multiple uses, and the actual use effect is better. At the same time, the second knurled part and the first knurled part are set in reverse, so the knurling operation does not need to be removed and reversely installed. The knurling operation can be completed by processing the metal parts only once, and the efficiency is high.

[0033] The pressure-treated knurling assembly of the present invention can realize pressure treatment of metal parts of multiple sizes. When the metal parts are in the pressure-treated knurling assembly, the distance between the second knurled part and the first knurled part can be changed to place metal parts bodies of different sizes and perform knurling operations. At the same time, the pressure-treated knurling assembly also has a certain protective effect, reducing the debris generated during the knurling operation and further improving the practical effect.

[0034] The knurled electromagnetic suction plate of the present invention can further fix the third knurled arc block and the first knurled arc block. The two knurled electromagnetic suction plates strengthen the connection at the gap between the third knurled arc block and the first knurled arc block by electromagnetic adsorption, reducing the shaking of the two. When the metal component bodies of different sizes are placed in the pressurized knurling assembly, the two knurled electromagnetic suction plates are respectively rotatably connected by the knurled limiting shafts, and the knurled electromagnetic suction plates can adjust their angles by themselves through the knurled limiting shafts, so that the knurled electromagnetic suction plates are always in a parallel state, so that the first knurled arc block and the third knurled arc block can be strengthened and connected by the two knurled electromagnetic suction plates, and the fixation is relatively firm, reducing the shaking of the first knurled arc block and the third knurled arc block, so that the pressurized knurling assembly is very stable when performing knurling operation on the metal component body.

[0035] The stability between the first knurled arc block, the second knurled arc block and the third knurled arc block is further improved by strengthening the limit limit assembly. The first knurled arc block, the second knurled arc block and the third knurled arc block all achieve angle change through the rotation of the angle rotation shaft, and the stepper motor itself has a locking function. On this basis, by moving the position of the friction plate, the friction plate applies an extrusion force to the angle rotation shaft, and the two generate a large friction force, which further reduces the situation where the angle rotation shaft rotates on its own, so that the first knurled arc block, the second knurled arc block and the third knurled arc block are still very stable after changing their angles, thereby ensuring the progress of the knurling operation.

[0056] The pressure treatment knurling assembly 300 is disposed at the bottom of the knurling top plate 200 and directly above the metal component clamping seat 105, and the pressure treatment knurling assembly 300 is movably connected to the knurling top plate 200;

[0057] The reinforcing limiting assembly 400 is disposed on one side of the pressurized knurling assembly 300, and the pressurized knurling assembly 300 changes the angle and limit position through the reinforcing limiting assembly 400;

[0058] The knurled component 500 is disposed inside the pressure-processing knurled component 300 , and the knurled component 500 includes a second knurled component 504 and a first knurled component 505 .

[0059] The present invention adopts a two-way movement method to pressurize the metal parts so that the metal parts have a knurling effect. At the same time, it will not affect the original tool operation, so that the machine tool has multiple effects and multiple uses, and the actual use effect is better. At the same time, the second knurled part 504 and the first knurled part 505 are set in reverse, so that the knurling operation does not need to be removed and reversely installed. The knurling operation can be completed by processing the metal parts only once, which is more efficient.

[0060] In this embodiment, preferably, Figure 1 , Figure 2 A moving hand wheel 103 is provided on one side of the tool holder 102 , and an operation counter 104 is provided on the top of the machine tool base 100 at the end of the x-axis moving component 101 .

[0061] In this embodiment, preferably, the pressurized knurling assembly 300 includes a third knurling arc block 305, a second knurling arc block 304, and a first knurling arc block 303, and the third knurling arc block 305, the second knurling arc block 304, and the first knurling arc block 303 are all arc structures, and the third knurling arc block 305 is consistent with the first knurling arc block 303 in arc length, and the second knurling arc block 304 is located between the third knurling arc block 305 and the first knurling arc block 303;

[0062] The first knurled arc block 303 and the second knurled arc block 304 are rotationally connected, and the second knurled arc block 304 and the third knurled arc block 305 are rotationally connected.

[0063] The pressure-treated knurling assembly 300 of the present invention can realize pressure treatment of metal parts of multiple sizes. When the metal parts are in the pressure-treated knurling assembly 300, the distance between the second knurled part 504 and the first knurled part 505 can be changed to place metal part bodies 600 of different sizes and perform knurling operations. At the same time, the pressure-treated knurling assembly 300 also has a certain protective effect, which reduces the debris generated during the knurling operation and further improves the practical effect.

[0064] The third knurled arc block 305 and the first knurled arc block 303 can exert a pressurizing effect on the metal component body 600, so that the first knurled member 505 and the second knurled member 504 are more closely fitted to the surface of the metal component body 600, thereby making the knurling operation proceed more quickly and stably, and the pattern is very exquisite and accurate.

[0065] In this embodiment, preferably, Figure 4 , Figure 5 , Figure 6 , Figure 7 The third knurled arc block 305 and the end of the first knurled arc block 303 away from the second knurled arc block 304 are both provided with a knurled electromagnetic suction plate 306, and the knurled electromagnetic suction plate 306 is rotatably connected to the third knurled arc block 305 and the first knurled arc block 303 respectively through a knurled limiting shaft 307;

[0066] The two knurled electromagnetic suction plates 306 have the same structure, and the gap between the third knurled arc block 305 and the first knurled arc block 303 is smaller than the fixed distance of the knurled electromagnetic suction plates 306 .

[0067] The knurled electromagnetic suction plate 306 of the present invention can further fix the third knurled arc block 305 and the first knurled arc block 303. The two knurled electromagnetic suction plates 306 strengthen the connection between the third knurled arc block 305 and the first knurled arc block 303 at the gap by electromagnetic adsorption, thereby reducing the shaking between the two. When the metal component body 600 of different sizes is placed in the pressurized knurled assembly 300, the two knurled electromagnetic suction plates 306 are respectively rotated by the knurled limiting shaft 307 The knurled electromagnetic suction plate 306 can adjust its angle by itself through the knurled limiting shaft 307, so that the knurled electromagnetic suction plate 306 is always in a parallel state, so that the first knurled arc block 303 and the third knurled arc block 305 can be strengthened and connected by the two knurled electromagnetic suction plates 306, and the fixation is relatively firm, reducing the shaking of the first knurled arc block 303 and the third knurled arc block 305, so that the pressurized knurling assembly 300 is very stable when performing knurling operation on the metal component body 600.

[0068] exist Figure 6In the embodiment, when the gap between the first knurled arc block 303 and the third knurled arc block 305 on the left side is large, the knurled electromagnetic suction plate 306 can be operated first. After the two knurled electromagnetic suction plates 306 attract each other, they will adjust their angles by themselves through the knurled limiting shaft 307, so that the two knurled electromagnetic suction plates 306 adjust themselves to a parallel state by the electromagnetic force; when the gap between the first knurled arc block 303 and the third knurled arc block 305 on the left side is small, similarly, the two knurled electromagnetic suction plates 306 can also attract each other by the electromagnetic force, and adjust their angles by themselves through the knurled limiting shaft 307, so that the two knurled electromagnetic suction plates 306 adjust themselves to a parallel state by the electromagnetic force, thereby achieving a fixing effect.

[0069] It is worth noting that the third knurled arc block 305, the second knurled arc block 304, and the first knurled arc block 303 themselves have a fixing effect, and the metal component body 600 can still be knurled normally. The two knurled electromagnetic suction plates 306 can fix the ends of the third knurled arc block 305 and the first knurled arc block 303, so that during the knurling operation, the ends of the first knurled arc block 303 and the third knurled arc block 305 will not shake, and the stability is higher.

[0070] In this embodiment, preferably, Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 An x-axis lateral moving member 301 is provided at the top of the third knurled arc block 305, and the x-axis lateral moving member 301 is movably connected to the knurled top plate 200, a knurled height adjustment rod 308 is provided at the bottom of the x-axis lateral moving member 301, and the knurled height adjustment rod 308 is connected to the third knurled arc block 305 through a knurled connecting clamp 309, a protective shell 302 is provided at the bottom of the x-axis lateral moving member 301, and the knurled height adjustment rod 308 is located in the protective shell 302.

[0071] The x-axis lateral moving member 301 moves in the same manner as the metal component clamping seat 105, both of which are prior arts. At the same time, the knurling height adjustment rod 308 can adjust the height of the pressurized knurling assembly 300, so that the first knurling arc block 303, the third knurling arc block 305, and the second knurling arc block 304 can adjust the height and wrap the metal component body 600 therein.

[0072] In this embodiment, preferably, Figure 4 , Fig. 9 , Fig.10 The knurled member 500 includes a second knurled member 504 and a first knurled member 505. A knurled inner seat 502 is provided on one side of the second knurled member 504. A knurled wheel 503 is connected to one side of the knurled inner seat 502 through a knurled support plate 501.

[0073] The second knurled member 504 and the first knurled member 505 have the same structure. The second knurled member 504 is installed on the inner wall of the second knurled arc block 304, and the first knurled member 505 is installed on the inner wall of the first knurled arc block 303.

[0074] When the metal component body 600 is placed in the third knurled arc block 305, the second knurled arc block 304, and the first knurled arc block 303, the surface of the metal component body 600 is respectively connected to the second knurled component 504 and the first knurled component 505, and a knurled pattern 601 is formed on the surface of the metal component body 600.

[0075] After the second knurled member 504 and the first knurled member 505 wrap the metal component body 600, as the first knurled arc block 303, the second knurled arc block 304, and the third knurled arc block 305 are in a closed state, the second knurled member 504 and the first knurled member 505 can apply pressure to the metal component body 600, so that the three fit more closely, the knurling operation efficiency is higher, and the metal component body 600 is more stable during the knurling operation.

[0076] In this embodiment, preferably, Figure 8 The second knurled member 504 and the first knurled member 505 are arranged in opposite directions, and the third knurled arc block 305 and the first knurled arc block 303 are always in a symmetrical state.

[0077] At the same time, the second knurled member 504 and the first knurled member 505 are arranged in reverse, so that the knurling operation does not need to be removed and installed in reverse, and the knurling operation can be completed by processing the metal part only once, which is more efficient.

[0078] In this embodiment, preferably, the reinforced limiting assembly 400 includes a placement box 401, which is fixed on the outer curved wall of the second knurled arc block 304, and the top and bottom of the placement box 401 are symmetrically provided with vertical plates 406, and an angle rotation shaft 403 is provided between the two vertical plates 406, and the ends of the angle rotation shaft 403 are provided with stepper motors 405, and the output shaft of the stepper motor 405 is connected to the end of the angle rotation shaft 403, and the side walls of the angle rotation shaft 403 are provided with L-shaped connecting plates 404, and the two L-shaped connecting plates 404 are respectively connected to the third knurled arc block 305 and the first knurled arc block 303.

[0079] By strengthening the limit assembly 400, the stability between the first knurled arc block 303, the second knurled arc block 304, and the third knurled arc block 305 is further improved. The first knurled arc block 303, the second knurled arc block 304, and the third knurled arc block 305 all achieve angle change through the rotation of the angle rotation shaft 403, and the stepper motor 405 itself has a locking function. On this basis, by moving the position of the friction plate 408, the friction plate 408 applies an extrusion force to the angle rotation shaft 403, and the two generate a large friction force, which further reduces the situation where the angle rotation shaft 403 rotates on its own, so that the first knurled arc block 303, the second knurled arc block 304, and the third knurled arc block 305 are still very stable after changing their angles, which can ensure the progress of the knurling operation.

[0080] The changing of the angles of the first knurled arc block 303 , the second knurled arc block 304 , and the third knurled arc block 305 is achieved by strengthening the limiting assembly 400 .
