Description

Technical Field

[0001] The invention belongs to the technical field of cylinder head processing equipment, and in particular relates to a multi-station tooling for horizontal milling of a cylinder head. Background Art

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

[0003] However, most of the tooling used for horizontal milling of cylinder heads in the prior art does not have a structure for collecting and cleaning debris, nor does it have a structure for detecting and marking the flatness of the grooves after milling. After the grooves are milled on the cylinder head, it is necessary to manually clean out the metal debris remaining in the grooves, and it is also necessary to manually inspect the grooves for uneven processing defects. The degree of automation is low, the operation is cumbersome, and the use is not convenient. In addition, the existing tooling used for horizontal milling of cylinder heads is generally designed for one processing position. When loading and unloading materials to replace the cylinder head, the milling operation of the groove needs to be stopped, and the processing efficiency is low. Summary of the invention

Technical personnel in this field 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 a cylinder head comprises a support frame 1, a plurality of processing position tables 2 horizontally arranged on the support frame 1, a collecting frame 3 arranged at the bottom of the processing position table 2, a fixed frame 7 arranged above the support frame 1, a moving component 2 6 for driving the fixed frame 7 to move horizontally, two moving components 3 8 arranged on the fixed frame 7, and a rotating component 9 connected to the moving component 3 8, each of the processing position tables 2 is provided with a group of clamping members 4, each of the processing position tables 2 is provided with a moving component 1 5 for driving the clamping member 4 to move forward and backward, the moving component 3 8 is used to drive the rotating component 9 to move up and down, and the two rotating components 9 are respectively connected with a milling cutter and a dust collection measurement mark component;

[0030] The dust suction measurement mark component includes a dust suction component and a measurement mark component. The dust suction component is used to suck and clean the residual metal debris in the groove after the milling cutter on the cylinder head is milled. The measurement mark component is used to measure and classify the unevenness of the side wall and bottom of the mark groove accordingly.

[0031] It should be noted that, in the present embodiment, the milling cutter and the dust measurement mark assembly respectively correspond to the tops of two adjacent grooves to be processed on the cylinder head, so as to facilitate simultaneous processing operations of the milling cutter and the dust measurement mark assembly.

[0032] It should be noted that, in this embodiment, a plurality of material dropping channels are provided on the processing table 2 to facilitate the large pieces of debris generated by milling to fall and be collected in the collection frame 3;

[0033] The clamping member 4 includes two clamp bases which are symmetrically arranged and connected to the support frame 1 or the processing table 2 for forward and backward sliding, and a clamp which is connected to the clamp base for horizontal sliding. The clamp is fixed to the clamp base by fixing bolts.

[0035] The clamping member 4 is driven to move forward and backward by the moving component 1 5, so that when a cylinder head is being processed on one of the workstations, that is, one of the processing table 2, the other clamping member 4 moves forward or backward to clamp another cylinder head, completing the loading and unloading operations of the cylinder head. The milling cutter moves along the moving component 2 6 through the rotating component 9 to perform continuous milling groove operations to process the cylinder head. Alternating loading can reduce the time for stopping to replace the cylinder head.

[0036] The second moving assembly 6 includes two symmetrically arranged side plates, a second screw rod rotatably connected to the two side plates, a second nut seat connected to the second screw rod through a ball nut pair, and a second servo motor driving the second screw rod to rotate. The fixing frame 7 is fixed on the second nut seat;

[0037] The moving component three 8 includes a screw rod three, a nut seat three connected to the screw rod three through a ball nut pair, and a servo motor three for driving the screw rod three to rotate. The rotating component 9 is fixed on the nut seat three.

[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 and used for mounting a fixed milling cutter or a dust collecting measurement marking assembly.

[0039] The rotating motor 91 drives the rotating disk 92 to rotate, and the rotating disk 92 drives the milling cutter to rotate, so that the cylinder head is milled to form an inclined upward groove, such as Figure 3As shown, it can be seen from the cross section of the groove that the lateral side wall of the groove is inclined upward, and small debris is not easy to fall off and is easy to accumulate inside the groove.

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

[0041] When it is necessary to collect the fine debris remaining in the groove, the rotating motor 91 drives the rotating disk 92 to rotate, and the rotating disk 92 drives the dust collection assembly to rotate, and the left and right side walls of the outer cover 11 are respectively pressed against the side walls of the groove, 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 fine debris.

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

[0043] It should be noted that, in the present embodiment, the telescopic member 15 is an electric telescopic rod, and the telescopic member 15 is used to drive the horizontal plate 16 and the components arranged at the bottom of the horizontal plate 16 to move up and down. When the dust suction component starts to extract and collect fine debris inside the groove, the telescopic member 15 can drive the horizontal plate 16 to move up, so that the marking pen 181 and the marking pen 29 do not contact the horizontal end surface above the groove on the cylinder head, and no marking is performed. After the dust suction component has been working for a period of time, the telescopic member 15 is driven to drive the horizontal plate 16 and the components arranged at the bottom of the horizontal plate 16 to move down, so that the marking pen 181 contacts the horizontal end surface above the groove on the cylinder head, and the marking pen 2 29 is higher than the horizontal end surface above the groove on the cylinder head.

[0044] Preferably, a horizontal sliding groove 21 is provided on the outer cover body 11, and a horizontal sliding shaft 20 slidably connected to the inside of the horizontal sliding groove 21 is provided on the side wall pressure plate 19, and 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 measuring mark assembly is driven to rotate together by the rotating disk 92. During the rotation, the side wall pressure plate 19 will be pressed against the vertical side wall of the groove under the elastic force of the spring 23. If the vertical side wall of the groove is uneven, the horizontal moving seat 18 and the marking pen 181 will be pulled to move together, so that the horizontal end face above the groove on the cylinder head is marked by the marking pen 181. The mark is a continuous circle. If the vertical side wall of the groove is uneven, an uneven line segment will also appear in the circle line segment. If the vertical side wall of the groove is not uneven, a smooth circular mark will be made. This mark is used to facilitate the subsequent classification and fine processing of the cylinder head.

[0046] It should be noted that the vertical side walls and the transverse side walls of the groove are processed by the same milling cutter. If the vertical side walls of the groove are uneven, the transverse side walls of the groove will generally also be uneven.

[0047] Preferably, the measurement marking assembly further includes a bottom pressing plate 24 vertically slidably connected to the side wall of the outer cover body 11 close to the horizontal movable seat 18, a rotating plate 27 rotatably connected to the other vertical plate 17, a fixed plate 28 fixed on the other vertical plate 17, a marking pen 29 connected to the fixed plate 28 for vertical sliding connection, and at least one elastic reset member 2 connected to the fixed plate 28 and the marking pen 29;

If a bulge appears at the bottom of the groove, the bottom pressure plate 24 will move up. The upward movement of the bottom pressure plate 24 will push the rotating plate 27 in contact with the top of the bottom pressure plate 24 to rotate upward, and the side of the rotating plate 27 in contact with the marking pen 29 will rotate downward, thereby pushing the marking pen 29 to move down and contact the horizontal end surface above the groove on the cylinder head, thereby marking. If a bulge appears at the bottom of the depression, the marking pen 29 will form a stroke mark on the horizontal end surface above the groove on the cylinder head, otherwise there will be no stroke mark; this mark is used to facilitate the subsequent classification and fine processing of the cylinder head.

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