[0040] In related technologies, chamfering equipment is often only applicable to one type of cylinder head and cannot meet the chamfering requirements of guide tubes on cylinder heads of different sizes and models. It cannot meet the processing requirements and has low processing accuracy.
[0041] In view of this, this embodiment provides a chamfering processing device 100, which aims to guide the workpiece 3 to be processed by setting a guide mechanism, thereby adjusting the position of the workpiece before entering the chamfering process, improving the processing accuracy, and at the same time, by setting a tool 222 that is easy to disassemble and replace, it can adapt to cylinder heads of different sizes, so as to solve the above-mentioned technical problems.
[0042] Figures 1 to 2 This is a schematic diagram of the chamfering device 100 according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the lead screw guide module 212 according to an embodiment of the present invention. Figure 1 and Figure 2In the figure, two directions that are substantially parallel to the upper surface of the base plate 7 and intersect each other are referred to as the first direction X and the third direction Z, and the first direction X is perpendicular to the third direction Z. The second direction Y is a direction that is substantially perpendicular to the base plate 7 (i.e., the vertical direction), and the second direction Y, the first direction X, and the third direction Z are all mutually perpendicular. In addition, the direction indicated by the arrow in the figure and the direction opposite to it are considered to be the same direction.
[0043] like Figures 1 to 3 As shown, according to an embodiment of the present invention, a chamfering processing device 100 is proposed. The chamfering processing device 100 includes a base plate 7 and a guide mechanism and a tool mechanism disposed on the base plate 7. The guide mechanism includes a first drive assembly 11 and a guide assembly 12. The first drive assembly 11 is connected to the guide assembly 12 and is used to drive the guide assembly 12 to guide the workpiece 3 to be processed to move along a first direction X. In this embodiment, the workpiece 3 to be processed is an engine cylinder head. The tool mechanism includes a second drive assembly 21 and a tool assembly 22. The tool assembly 22 includes a tool holder 221 and a plurality of tools 222. Each tool 222 is detachably connected to the tool holder 221. In actual production, different tools 222 can be replaced according to different models of cylinder heads to achieve chamfering operations on different specifications of guide tubes. The second drive assembly 21 is connected to the tool holder 221 and is used to drive the tool holder 221 to move along a second direction Y. The second direction Y is perpendicular to the first direction X.
[0044] The chamfering processing device 100 of this utility model is equipped with a guiding mechanism and a tooling mechanism. The guiding mechanism includes a first driving component 11 and a guiding component 12. The first driving component 11 drives the guiding component 12 to move, and the guiding component 12 guides the workpiece 3 to be processed to move along a first direction X, which is the conveying direction of the workpiece 3. This adjusts the position of the cylinder head before it enters the chamfering process, ensuring that the cylinder head posture is within a reasonable error range, improving processing accuracy, and adapting to cylinder heads of different sizes. The tooling mechanism includes a second driving component 21 and a tooling component 22. The second driving component 21 drives the tooling component 22 to move along a second direction Y, thereby adjusting the position of the tool 222 before the chamfering process, improving processing accuracy. The tooling component 22 includes a tool holder 221 and multiple tools 222 detachably connected to it. By setting detachable tools 222, it is easy to replace different tools 222, which can adapt to the chamfering requirements of guide tubes on different models of cylinder heads, realize chamfering operations on guide tubes of different specifications, and has strong applicability.
[0045] In some embodiments of this utility model, the guide assembly 12 includes at least two guide plates arranged opposite each other along the third direction Z, and a positioning space is formed between the two guide plates. The first drive assembly 11 includes at least two first cylinders, which are respectively connected to the two guide plates. The first cylinders are used to adjust the spacing of the positioning space.
[0046] Specifically, the chamfering processing device 100 also includes a conveyor roller 6, which drives the cylinder head to move along the first direction X. The guide assembly 12 includes a first guide plate 121 and a second guide plate 122 disposed opposite to each other on both sides of the conveyor roller 6, forming a positioning space between the first guide plate 121 and the second guide plate 122. The first drive assembly 11 includes a first cylinder I 111 and a first cylinder II 112, wherein the piston rod of the first cylinder I 111 is connected to the first guide plate 121, and the piston rod of the first cylinder II 112 is connected to the second guide plate 122. When the cylinder head is placed on the conveyor roller 6 and moves, the first cylinder I 111 and the first cylinder II 112 respectively drive the first guide plate 121 and the second guide plate 122 to move closer to each other or further away from each other to adjust the positioning space distance, thereby adjusting the position of the cylinder head before entering the chamfering process, ensuring that the cylinder head posture is within a reasonable error range, improving the processing accuracy of the cylinder head. In addition, by adjusting the positioning space distance, it can adapt to different models of cylinder heads, meet processing requirements, and has strong applicability.
[0047] In some embodiments of this utility model, each guide plate has a guide surface facing the guide plate opposite it. The guide surface is arc-shaped, and the distance between the two guide surfaces gradually decreases along the first direction X. Specifically, the first guide plate 121 has a first guide surface, and the second guide plate 122 has a second guide surface. Both the first and second guide surfaces are arc-shaped, and the distance between the first and second guide surfaces gradually decreases along the first direction X. By setting arc-shaped guide surfaces and gradually decreasing distance between the two guide surfaces along the first direction X, the cylinder head can be easily and correctly adjusted to the correct position by the guidance of the first guide plate 121 and the second guide plate 122 when the initial position of the cylinder head is not good, ensuring that the position of the cylinder head is within a reasonable error range and further improving the machining accuracy.
[0048] In some embodiments of this utility model, a plurality of guide wheels 1211 are provided on the guide surface, and the plurality of guide wheels 1211 are spaced apart along the extension direction of the guide surface.
[0049] Specifically, the guide wheel 1211 is made of plastic, which prevents scratches on the side of the cylinder head when it contacts the guide wheel 1211 during cylinder head transport. By setting multiple guide wheels 1211 on the guide surface, the cylinder head is easily guided and positioned when transported along the first direction X, ensuring that the cylinder head posture is within a reasonable error range and improving the processing accuracy of the chamfering process.
[0050] In some embodiments of this utility model, such as Figure 3 As shown, the second drive assembly 21 includes a first motor 211 and a lead screw guide module 212. The lead screw guide module 212 is connected to the first motor 211 and is used to drive the first motor 211 to move along the first direction X. The output end of the first motor 211 is connected to the tool assembly 22.
[0051] Specifically, it also includes a fixed plate 214 and multiple lead screw support seats 213. The fixed plate 214 is installed on the top of the multiple lead screw support seats 213. The lead screw guide module 212 is installed on the lower end surface of the fixed plate 214. The lead screw guide module 212 includes a second motor 2121, a lead screw 2122, a moving plate 2123, a lead screw bearing seat 2124, and a coupling 2125. The length direction of the lead screw 2122 is set along the first direction X. The output shaft of the second motor 2121 is equipped with a coupling 2125 connected to the lead screw 2122. The lead screw 2122 is installed on the lead screw bearing seat 2124. The moving plate 2123 is connected to the lead screw 2122. The second motor 2121 is a stepper motor. The first motor 211 is installed at the bottom of the moving plate 2123. The first motor 211 is a spindle motor. During chamfering, the second motor 2121 drives the moving plate 2123 to move along the lead screw 2122. The second motor 2121 drives the lead screw 2122 to rotate, which in turn drives the moving plate 2123 connected to the lead screw 2122 to move along the lead screw 2122. Once it reaches the preset position, the first motor 211 drives the tool assembly 22 to move vertically to chamfer the cylinder head guide. By setting a high-precision lead screw guide module 212, the first motor 211 can be accurately positioned in the cylinder head movement direction. Then, the tool 222 is used to perform the chamfering process on the cylinder head, thereby improving the processing accuracy. It is applicable to different cylinder head guides and similar chamfering processes, making it highly versatile.
[0052] In some embodiments of this utility model, the chamfering processing device 100 further includes a limiting mechanism, which includes a third driving member and a limiting member 41. The third driving member is connected to the limiting member 41, and the third driving member is used to drive the limiting member 41 to limit the workpiece 3 to be processed in the second direction Y.
[0053] Specifically, the third driving component includes a second cylinder, and the limiting component 41 includes a limiting block 411. The second cylinder is connected to the limiting block 411. The second cylinder is used to drive the limiting block 411 to move along the second direction Y. When performing chamfering, after the cylinder head is conveyed to the preset position by the conveying roller 6, the second cylinder drives the limiting block 411 to move upward along the second direction Y, so that the top of the limiting block 411 abuts against the bottom of the cylinder head, so as to accurately position the cylinder head, facilitate the chamfering of the tool mechanism, and ensure the machining accuracy.
[0054] In some embodiments of this utility model, the chamfering processing device 100 further includes a clamping mechanism, which includes a fourth driving component 51 and a clamping component 52. The fourth driving component 51 is connected to the clamping component 52. The fourth driving component 51 is used to drive the clamping component 52 to clamp the workpiece 3 to be processed in the third direction Z. The third direction Z, the first direction X, and the second direction Y are perpendicular to each other.
[0055] Specifically, the clamping assembly 52 includes at least two opposing clamping plates 521, forming a clamping space between them. The fourth drive assembly 51 includes at least two third cylinders 511, each connected to one of the clamping plates 521. The third cylinders 511 are used to adjust the spacing of the clamping space. During chamfering, the two third cylinders 511 drive the two clamping plates 521 to move closer to or further away from each other. When the two clamping plates 521 move closer to each other, they clamp and fix the cylinder head, further accurately positioning and fixing it to facilitate chamfering. After the chamfering is completed, the two third cylinders 511 drive the two clamping plates 521 to move further away from each other, thereby releasing the cylinder head and allowing it to be conveyed to the next process via the transfer rollers 6.
[0056] The chamfering processing device 100 of this utility model is equipped with a guiding mechanism and a cutting tool mechanism. The guiding mechanism includes a first driving component 11 and a guiding component 12. The first driving component 11 drives the guiding component 12 to move, and the guiding component 12 guides the workpiece 3 to be processed to move along the first direction X, thereby adjusting its position before the cylinder head enters the chamfering process, ensuring that the cylinder head posture is within a reasonable error range, improving processing accuracy, and adapting to cylinder heads of different sizes. The cutting tool mechanism includes a second driving component 21 and a cutting tool component 22. The second driving component 21 drives the cutting tool component 22 to move along the second direction Y, thereby adjusting the position of the cutting tool 222 before the chamfering process, improving processing accuracy. The cutting tool component 22 includes a cutting tool holder 221 and multiple cutting tools 222 detachably connected to it. By setting detachable cutting tools 222, it is easy to replace different cutting tools 222, which can adapt to the chamfering requirements of guide tubes on different models of cylinder heads, realize chamfering operations on guide tubes of different specifications, and has strong applicability.
