Description

Technical Field

[0001] This invention belongs to the technical field of cylinder head processing equipment, specifically relating to a multi-station tooling for horizontal milling of cylinder heads. Background Technology

[0002] The cylinder head is a key component of the engine. The dimensions of each part of the cylinder head can be precisely controlled through milling. During the production and processing of the cylinder head, grooves can be made on the surface of the cylinder head through milling. However, if the opening of the groove is inclined upward, larger chips can easily fall into the groove during milling, but smaller metal chips will easily accumulate inside the groove and are not easy to clean out.

[0003] However, existing tooling for horizontal milling of cylinder heads often lacks a structure for collecting and cleaning debris, as well as a structure for marking and checking the flatness of the milled grooves. Therefore, after the cylinder head grooves are milled, the metal debris remaining inside the grooves needs to be manually cleaned, and the grooves need to be manually checked for unevenness or machining defects. This results in low automation, cumbersome operation, and inconvenience. In addition, existing tooling for horizontal milling of cylinder heads is generally designed for a single machining station. When loading and unloading cylinder heads, the milling operation of the grooves needs to be stopped, resulting in low processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station tooling for horizontal milling of cylinder heads in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A multi-station tooling for horizontal milling of cylinder heads includes a support frame, several machining stations horizontally mounted on the support frame, a collection frame at the bottom of the machining station, a fixed frame above the support frame, a second moving component for driving the fixed frame to move horizontally, two third moving components mounted on the fixed frame, and a rotating component connected to the third moving component. Each machining station is provided with a set of clamping members, and each machining station is provided with a first moving component for driving the clamping members to move back and forth. The third moving component is used to drive the rotating component to move up and down. The two rotating components are respectively connected to a milling cutter and a dust collection measuring mark component.

[0007] The dust collection and measurement marking assembly includes a dust collection assembly and a measurement marking assembly. The dust collection assembly is used to collect residual metal debris in the grooves on the cylinder head after milling. The measurement marking assembly is used to measure and classify the unevenness of the sidewalls and bottom of the grooves accordingly.

[0008] As a further optimization of the present invention, the rotating assembly includes an outer protective frame, a rotating motor disposed inside the outer protective frame, and a rotating disk disposed on the output shaft of the rotating motor for mounting and fixing a milling cutter or a dust collection measuring mark assembly.

[0009] As a further optimization of the present invention, the dust collection assembly includes a connecting plate connected to the rotating disk, an outer cover detachably connected to the bottom of the connecting plate, an inner support frame disposed inside the outer cover, a dust collection hood fixed on the inner support frame and located inside the outer cover, and a vacuum cleaner connected to the dust collection hood through a pipe. The left and right side walls of the outer cover are in contact with the side walls of the groove, respectively.

[0010] As a further optimization of the present invention, the measuring mark assembly includes a telescopic member disposed at the bottom of the connecting plate, a horizontal plate disposed at the bottom of the telescopic end of the telescopic member, two vertical plates symmetrically disposed at the bottom of the horizontal plate, a horizontally sliding seat horizontally slidably connected to the two vertical plates, a marking pen disposed on the horizontally sliding seat for contacting the horizontal end face above the groove on the cylinder head, an elastic reset member disposed between one of the vertical plates and the horizontally sliding seat, and a side wall abutment plate horizontally slidably connected to the side wall of the outer cover near the side of the horizontally sliding seat and connected to one end of the horizontally sliding seat, wherein the side wall abutment plate contacts the vertical side wall of the groove.

[0011] As a further optimization of the present invention, a horizontal sliding groove is provided on the outer cover, and a horizontal sliding shaft is provided on the side wall pressure plate and slidably connected inside the horizontal sliding groove.

[0012] As a further optimization of the present invention, the measuring mark assembly further includes a bottom pressure plate that is vertically slidably connected to the side wall of the outer cover near the horizontal moving seat, a rotating plate that is rotatably connected to another vertical plate, a fixed plate that is fixedly mounted on another vertical plate, a second marking pen that is slidably connected to the fixed plate, and at least one second elastic reset member that is connected to the fixed plate and the second marking pen.

[0013] Both the top of the bottom pressure plate and the top of the marker pen are rotatably connected to rollers that press against the bottom of the rotating plate.

[0014] As a further optimization of the present invention, a vertical sliding groove is provided on the outer cover, and a vertical sliding shaft is provided on the bottom pressure plate and slidably connected inside the vertical sliding groove.

[0015] As a further optimization of the present invention, the first elastic reset component includes a guide rod first horizontally disposed on one of the vertical plates and passing through the horizontal moving seat, and a spring first disposed between the vertical plate and the horizontal moving seat and sleeved outside the guide rod first; the second elastic reset component includes a guide rod second vertically disposed on the fixed plate and passing through the marker pen second, and a spring second disposed between the fixed plate and the marker pen second and sleeved outside the guide rod second.

[0016] As a further optimization of the present invention, the two side walls of the outer cover and the side wall pressure plate are rotatably connected with a number of rotating balls on the side of the vertical side wall of the groove.

[0017] The beneficial effects of this invention are as follows:

[0018] 1) This invention uses a structure design with multiple processing stations, each of which is equipped with a clamping component and a moving component. When the cylinder head on one of the processing stations is being grooved and milled, the clamping component can be moved forward or backward by the moving component. Then, the cylinder head on the other processing station can be loaded and unloaded manually. By alternating the loading and unloading of cylinder heads in this way, a continuous cylinder head groove milling operation can be formed. This reduces the time spent on stopping the cylinder head groove milling operation to change the cylinder head. It is convenient to use and can improve processing efficiency.

[0019] 2) The present invention can extend the dust collection component into the groove milled on the cylinder head to extract and collect residual metal debris, achieving a better cleaning effect, with a high degree of automation and reducing manual operation;

[0020] 3) In this invention, the rotating disk drives the measuring marking assembly to rotate together. Under the elastic force of the spring, the side wall pressure plate will press against the vertical side wall of the groove. If the vertical side wall of the groove is uneven, it will pull the horizontal moving seat and the marking pen to move together. Thus, the marking pen will mark the horizontal end face above the groove on the cylinder head. This marking will facilitate the subsequent classification and fine processing of the cylinder head.

[0021] 4) In this invention, the rotating disk drives the measuring mark assembly to rotate together. Under the elastic force of the second spring, the bottom pressure plate presses against the bottom of the groove. If the bottom of the groove protrudes, the bottom pressure plate will move upward. The upward movement of the bottom pressure plate will push the rotating plate that is in contact with the top of the bottom pressure plate to rotate upward. Then, the side of the rotating plate that is in contact with the second mark pen will rotate downward, thereby pushing the second mark pen to move downward and contact the horizontal end face above the groove on the cylinder head for marking. This marking facilitates the subsequent classification and fine processing of the cylinder head. Attached Figure Description

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] like Figure 1-5 As shown, a multi-station tooling for horizontal milling of cylinder heads includes a support frame 1, several machining platforms 2 horizontally arranged on the support frame 1, a collection frame 3 at the bottom of the machining platform 2, a fixed frame 7 above the support frame 1, a second moving component 6 for driving the fixed frame 7 to move horizontally, two third moving components 8 arranged on the fixed frame 7, and a rotating component 9 connected to the third moving component 8. Each machining platform 2 is provided with a set of clamping members 4, and each machining platform 2 is provided with a first moving component 5 for driving the clamping members 4 to move back and forth. The third moving component 8 is used to drive the rotating component 9 to move up and down. The two rotating components 9 are respectively connected to a milling cutter and a dust collection measuring mark assembly.

[0030] The dust collection and measurement marking assembly includes a dust collection assembly and a measurement marking assembly. The dust collection assembly is used to collect residual metal debris in the grooves on the cylinder head after milling. The measurement marking assembly is used to measure and classify the unevenness of the sidewalls and bottom of the grooves accordingly.

[0031] It should be noted that, in this embodiment, the milling cutter and the dust collection measurement mark assembly are respectively located above the two adjacent grooves that need to be machined on the cylinder head, so that the milling cutter and the dust collection measurement mark assembly can perform machining operations simultaneously.

[0032] It should be noted that, in this embodiment, the processing table 2 is provided with several material drop channels, which facilitates the collection of larger pieces of debris generated during milling into the collection frame 3.

[0033] The clamping component 4 includes two clamping bases symmetrically arranged on the left and right and slidably connected to the support frame 1 or the processing table 2, and a clamp slidably connected to the clamping bases horizontally. The clamps and clamping bases are fixedly connected by fixing bolts.

[0034] The moving component 5 includes two lead screws, a nut seat connected to the lead screws via a ball nut pair, a servo motor that drives the two lead screws to rotate synchronously, and a synchronizing element. The clamp base is fixed on the nut seat. The synchronizing element includes two synchronous pulleys respectively sleeved on the two lead screws and a synchronous belt disposed between the two synchronous pulleys.

[0035] The moving component 5 drives the clamping component 4 to move back and forth, so that when one workstation, namely one machining table 2, is machining a cylinder head, the other clamping component 4 moves forward or backward to clamp another cylinder head, thus completing the loading and unloading operation of the cylinder head. The milling cutter moves along the moving component 6 through the rotating component 9 to continuously mill the groove, thus machining the cylinder head. The alternating loading can reduce the time spent changing cylinder heads.

[0036] The second moving component 6 includes two symmetrically arranged side plates, a second lead screw rotatably connected to the two side plates, a second nut seat connected to the second lead screw via a ball nut pair, and a second servo motor that drives the second lead screw to rotate. The fixed frame 7 is fixed on the second nut seat.

[0037] The moving component 3 8 includes a lead screw 3, a nut seat 3 connected to the lead screw 3 via a ball nut pair, and a servo motor 3 that drives the lead screw 3 to rotate. The rotating component 9 is fixed on the nut seat 3.

[0038] Preferably, the rotating assembly 9 includes an outer protective frame, a rotating motor 91 disposed inside the outer protective frame, and a rotating disk 92 disposed on the output shaft of the rotating motor 91 for mounting and fixing a milling cutter or a dust collection measuring mark assembly.

[0039] The rotating motor 91 drives the rotating disk 92 to rotate, which in turn drives the milling cutter to rotate, thereby milling an upwardly inclined groove into the cylinder head. Figure 3As shown in the cross-section of the groove, the lateral sidewalls of the groove slope upwards, making it difficult for small debris to fall off and easy for it to accumulate inside the groove.

[0040] Preferably, the vacuuming assembly includes a connecting plate 10 connected to the rotating disk 92, an outer cover 11 detachably connected to the bottom of the connecting plate 10, an inner support frame 12 disposed inside the outer cover 11, a vacuum hood 13 fixed on the inner support frame 12 and located inside the outer cover 11, and a vacuum cleaner 14 connected to the vacuum hood 13 through a pipe. The left and right side walls of the outer cover 11 are in contact with the side walls of the groove, respectively.

[0041] When it is necessary to collect the small debris remaining inside the groove, the rotating motor 91 drives the rotating disk 92 to rotate, and the rotating disk 92 drives the dust collection component to rotate. The left and right side walls of the outer cover 11 press against the side walls of the groove respectively, and then the vacuum cleaner 14 and the dust cover 13 are aimed at the inside of the groove to extract and collect the remaining small debris.

[0042] Preferably, the measuring marking assembly includes a telescopic member 15 disposed at the bottom of the connecting plate 10, a horizontal plate 16 disposed at the bottom of the telescopic end of the telescopic member 15, two vertical plates 17 symmetrically disposed at the bottom of the horizontal plate 16, a horizontally sliding seat 18 horizontally slidably connected to the two vertical plates 17, a marking pen 181 disposed on the horizontally sliding seat 18 for contacting the horizontal end face above the groove on the cylinder head, an elastic reset member 1 disposed between one of the vertical plates 17 and the horizontally sliding seat 18, and a side wall abutment plate 19 horizontally slidably connected to the side wall of the outer cover 11 near the horizontally sliding seat 18 and connected to one end of the horizontally sliding seat 18, wherein the side wall abutment plate 19 contacts the vertical side wall of the groove.

[0043] It should be noted that in this embodiment, the telescopic member 15 is an electric telescopic rod. The telescopic member 15 is set to move the horizontal plate 16 and the component located at the bottom of the horizontal plate 16 up and down together. When the dust collection assembly starts to extract and collect small debris inside the groove, the telescopic member 15 can be moved up to move the horizontal plate 16, so that the marking pen 181 and the marking pen 29 do not contact the horizontal end face above the groove on the cylinder head and are not marked. After the dust collection assembly has been working for a period of time, the telescopic member 15 can be moved down to move the horizontal plate 16 and the component located at the bottom of the horizontal plate 16 together, so that the marking pen 181 contacts the horizontal end face above the groove on the cylinder head, and the marking pen 29 is higher than the horizontal end face above the groove on the cylinder head.

[0044] Preferably, the outer cover 11 is provided with a horizontal sliding groove 21, and the side wall pressure plate 19 is provided with a horizontal sliding shaft 20 that is slidably connected inside the horizontal sliding groove 21. The movement of the side wall pressure plate 19 is limited by the horizontal sliding shaft 20 and the horizontal sliding groove 21.

[0045] The rotating disk 92 drives the measuring marking assembly to rotate together. During rotation, the side wall pressure plate 19, under the elastic force of the spring 23, will press against the vertical side wall of the groove. If the vertical side wall of the groove is uneven, it will pull the horizontal moving seat 18 and the marking pen 181 to move together. Thus, the marking pen 181 marks the horizontal end face above the groove on the cylinder head. The mark is a continuous circle. If the vertical side wall of the groove is uneven, the circle will also have corresponding uneven lines. If the vertical side wall of the groove is not uneven, it will be a smooth circular mark. This mark is used to facilitate subsequent classification and fine processing of the cylinder head.

[0046] It should be noted that the vertical and horizontal sidewalls of the groove are machined using the same milling cutter. If the vertical sidewall of the groove is uneven, the horizontal sidewall of the groove will generally also be uneven.

[0047] Preferably, the measuring marking assembly further includes a bottom pressure plate 24 that is vertically slidably connected to the side wall of the outer cover 11 near the horizontal moving seat 18, a rotating plate 27 that is rotatably connected to another vertical plate 17, a fixing plate 28 that is fixedly mounted on another vertical plate 17, a marking pen 29 that is slidably connected to the fixing plate 28, and at least one elastic reset member 2 that is connected to the fixing plate 28 and the marking pen 29.

[0048] The top of the bottom pressure plate 24 and the top of the marker pen 29 are both rotatably connected to rollers and press against the bottom of the rotating plate 27.

[0049] The rotating disk 92 drives the measuring mark assembly to rotate together. Under the elastic force of the second spring 31, the bottom pressure plate 24 presses against the bottom of the groove. If the bottom of the groove protrudes, the bottom pressure plate 24 will move upward. The upward movement of the bottom pressure plate 24 will push the rotating plate 27, which is in contact with the top of the bottom pressure plate 24, to rotate upward. Then, the side of the rotating plate 27 that is in contact with the second marking pen 29 will rotate downward, thereby pushing the second marking pen 29 downward to contact the horizontal end face above the groove on the cylinder head, thus making a mark. If the bottom of the groove protrudes, the second marking pen 29 will form a scribing mark on the horizontal end face above the groove on the cylinder head; otherwise, there will be no scribing mark. This mark is used to facilitate subsequent classification and fine processing of the cylinder head.

[0050] Preferably, the outer cover 11 is provided with a vertical sliding groove 26, and the bottom pressure plate 24 is provided with a vertical sliding shaft 25 that is slidably connected inside the vertical sliding groove 26. The movement of the bottom pressure plate 24 is limited by the vertical sliding shaft 25 and the vertical sliding groove 26.

[0051] Preferably, the first elastic reset member includes a guide rod 22 horizontally disposed on one of the vertical plates 17 and passing through the horizontal moving seat 18, and a spring 23 disposed between the vertical plate 17 and the horizontal moving seat 18 and sleeved outside the guide rod 22. The second elastic reset member includes a guide rod 30 vertically disposed on the fixed plate 28 and passing through the marker pen 29, and a spring 31 disposed between the fixed plate 28 and the marker pen 29 and sleeved outside the guide rod 30.

[0052] Preferably, the two side walls of the outer cover 11 and the side wall pressure plate 19 are rotatably connected with a number of rotating balls 32 near the vertical side wall of the groove. The rotating balls 32 are provided to assist the outer cover 11 and the side wall pressure plate 19 in rotating along the groove, so as to facilitate rotation.

[0053] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
