Description

Technical Field

[0001] This utility model relates to the field of engine cylinder head clamping technology, specifically to an engine cylinder head clamping fixture. Background Technology

[0002] The cylinder head is an essential component of an engine. Mounted on top of the cylinder block, it seals the cylinder from above and forms the combustion chamber. It is constantly in contact with high-temperature, high-pressure combustion gases, thus bearing significant thermal and mechanical loads. Water-cooled engines have a cooling water jacket inside the cylinder head, and the cooling water holes on the lower end face of the cylinder head communicate with the cooling water holes in the cylinder block, using circulating water to cool the high-temperature components such as the combustion chamber. During the machining process of the cylinder head, it is usually necessary to clamp it using a fixture.

[0003] The existing utility model patent CN208163149U proposes an automated cylinder head clamp, which uses two motors in the base plate and a transmission device to drive the four corner shafts, thereby causing the baffles to move relative to each other / opposite to achieve automatic clamping and loosening of the cylinder head.

[0004] As described in the above technical solution, two motors work together with a transmission device to drive the four corner shafts, thereby driving the corresponding baffles to clamp and release the cylinder head. However, the above device has the problems of complex structure and high maintenance cost. The transmission device is set inside the base plate, which increases the complexity of the entire fixture and the difficulty of later maintenance. At the same time, adding a transmission device inside the fixture increases the manufacturing difficulty and cost of the fixture, and also increases the cost of later maintenance.

[0010] The cylinder body is located on the side of the second vertical plate away from the cylinder head;

[0011] The piston rod is mounted on the cylinder body, and the second vertical plate has a clearance hole corresponding to the piston rod. The piston rod passes through the clearance hole and is detachably connected to the clamping plate.

[0012] Optionally, the clamping disc includes a disc body and an abutment post, wherein,

[0013] The disc body is detachably connected to the piston rod;

[0014] The abutment posts include multiple posts, all located on the side of the disc facing the end face, for abutting against the end face.

[0015] Optionally, the second clamping assembly further includes a limiting rod, which is disposed between the clamping disc and the second upright plate, and is used to limit and support the clamping disc after it is clamped on the corresponding end face of the cylinder head.

[0016] Optionally, the second upright plate has an insertion through hole for sliding insertion of the limiting rod at the corresponding position. The limiting rod can pass through the insertion through hole and abut against the clamping plate. One end of the limiting rod corresponding to the insertion through hole is provided with an external thread, and the insertion through hole is provided with an internal thread that matches the external thread at the end of the limiting rod, for fixing the limiting rod between the second upright plate and the clamping plate.

[0017] Optionally, the outer surface of the limiting rod is symmetrically provided with clamping grooves for clamping the limiting rod for rotational fixing or release of fixing.

[0018] Optionally, the abutment member includes a first mounting block and an abutment block, wherein,

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-5 This embodiment proposes an engine cylinder head clamp for clamping a cylinder head 1. The cylinder head 1 has end faces 101 extending outward from both symmetrical ends. The engine cylinder head clamp includes a base 2, a first clamping component 3, and a second clamping component 4.

[0039] like Figure 1-2 As shown, the first clamping assembly 3 includes a first upright plate 31 and an abutment member 32. The first upright plate 31 is vertically disposed on the base 2 and corresponds to the end face 101 of one end of the cylinder head 1. The abutment member 32 is disposed on one side of the corresponding end face 101 of the first upright plate 31 and is used to abut against the end face 101. The second clamping assembly 4 includes a second upright plate 41, a driving member 42 and a clamping disk 43. The second upright plate 41 is vertically disposed on the base 2 and corresponds to the end face 101 of the cylinder head 1 away from the first upright plate 31. The driving member 42 is disposed on the second upright plate 41. The clamping disk 43 is disposed on the side of the second upright plate 41 facing the end face 101 and is detachably connected to the driving member 42. It is used to clamp the cylinder head 1 in cooperation with the abutment member 32 under the drive of the driving member 42.

[0040] Specifically, during the clamping process, the cylinder head 1 is placed between two vertical plates, with the two end faces 101 of the cylinder head 1 facing the first vertical plate 31 and the second vertical plate 41 respectively. The end face 101 of the cylinder head 1 facing the first vertical plate 31 is then abutted against the abutment member 32 of the first vertical plate 31. The transverse clamping disk 43 is moved by the driving member 42 to clamp the other end face 101 of the cylinder head 1, thereby completing the clamping of the cylinder head 1. The clamping is quick and convenient. At the same time, the base 2, vertical plates, clamping disk 43 and other components are all independent modules, which are easy to disassemble and assemble. Later maintenance only requires the replacement of some parts, without disassembling the entire transmission mechanism, reducing maintenance difficulty and cost.

[0041] In some embodiments, such as Figure 4-5 As shown, the drive component 42 includes a cylinder body 421 and a piston rod 422; the cylinder body 421 is fixed to the side of the second vertical plate 41 away from the cylinder head 1, and the piston rod 422 is mounted on the cylinder body 421; the second vertical plate 41 has a clearance hole 401 corresponding to the piston rod 422, and the piston rod 422 passes through the clearance hole 401 and is detachably connected to the clamping plate 43; the clamping plate 43 includes a plate body 431 and a plurality of abutment posts 432; the plate body 431 is detachably connected to the piston rod 422, and the abutment posts 432 are all located on the side of the plate body 431 facing the end face 101 of the cylinder head 1, for abutting the end face 101.

[0042] Specifically, during clamping, the cylinder body 421 directly drives the piston rod 422 to extend linearly. After passing through the clearance hole 401, the piston rod 422 pushes the clamping plate 43 forward to clamp the cylinder head 1. During the clamping process, multiple abutment posts 432 disperse the concentrated clamping force into a multi-point evenly distributed pressure. The multiple abutment posts 432 can be arranged according to the structure of the corresponding end face 101 to reduce the local stress on the end face 101 of the cylinder head 1 and avoid indentation or deformation. The plate 431 can be replaced independently after wear without replacing the entire piston rod 422, which is convenient for maintenance and reduces spare parts costs. At the same time, the detachable connection between the piston rod 422 and the clamping plate 43 allows for quick replacement of the appropriate clamping plate 43 for different cylinder heads 1, improving the applicability of the fixture.

[0043] In some embodiments, such as Figure 4-5As shown, the second clamping assembly 4 also includes a limiting rod 44, which is located between the clamping plate 43 and the second vertical plate 41. The limiting rod 44 is used to limit and support the clamping plate 43 after it is clamped on the end face 101 of the cylinder head 1. The second vertical plate 41 has an insertion through hole 402 for sliding insertion of the limiting rod 44 at the corresponding position. The limiting rod 44 can pass through the insertion through hole 402 and abut against the clamping plate 43. One end of the limiting rod 44 corresponding to the insertion through hole 402 is provided with an external thread, and the insertion through hole 402 is provided with an internal thread that matches the external thread at the end of the limiting rod 44 for abutment and fixation. The outer surface of the limiting rod 44 is symmetrically provided with clamping grooves 403 for clamping the limiting rod 44 for rotational fixation or release of fixation.

[0044] Specifically, when the clamping plate 43 is clamped on the corresponding end face 101 of the cylinder head 1, the limiting rod 44 is inserted through the insertion through hole 402, so that the external thread of the limiting rod 44 contacts the internal thread of the insertion through hole 402. At this time, the limiting rod 44 is clamped in the clamping groove 403 of the limiting rod 44 by an external clamping tool, and the limiting rod 44 is rotated to make it threadedly connected with the insertion through hole 402 until the end of the limiting rod 44 facing the clamping plate 43 abuts against the clamping plate 43, thereby changing the continuous pressure holding of the cylinder to the rigid support of the second vertical plate 41 on the clamping plate 43, thereby reducing the cylinder load and extending its service life.

[0045] In some embodiments, such as Figure 2-3 As shown, the abutment 32 includes a first mounting block 321 and an abutment block 322. The first mounting block 321 is detachably disposed on the side of the first upright plate 31 facing the end face 101 of the cylinder head 1. The abutment block 322 is disposed on the end of the first mounting block 321 facing the end face 101 and can abut against the end face 101 to cooperate with the clamping disc 43 to clamp the cylinder head 1.

[0046] Specifically, during clamping, the abutment block 322 directly contacts the end face 101 to cooperate with the clamping plate 43 to clamp the two end faces 101 of the cylinder head 1. At the same time, the detachable connection of the first mounting block 321 means that after the abutment block 322 is worn, only the corresponding first mounting block 321 needs to be replaced, avoiding the need to replace the entire upright plate and saving maintenance costs. In addition, by replacing the abutment block 322 with different shapes or materials, it can quickly adapt to different cylinder head 1 end faces 101, improving the versatility of the fixture.

[0047] In some embodiments, such as Figure 2-3 As shown, the engine cylinder head fixture also includes a second mounting block 5 and a insert rod 6. The second mounting block 5 is detachably mounted on the side of the first upright plate 31 facing the corresponding end face 101 of the cylinder head 1. The insert rod 6 is mounted on the end of the second mounting block 5 facing the corresponding end face 101 of the cylinder head 1 and corresponds to the mounting hole of the end face 101 itself, and is used to position the cylinder head 1.

[0048] Specifically, for the mounting holes on the end face 101 of the cylinder head 1, the second mounting block 5 with the insert rod 6 is installed to the corresponding position on the first upright plate 31. When placing the cylinder head 1, the insert rod 6 is directly inserted into the original mounting hole on the corresponding end face 101 of the cylinder head 1, so as to achieve quick positioning of the cylinder head 1 without additional alignment; thereby speeding up the clamping speed and shortening the auxiliary time.

[0049] In some embodiments, such as Figure 2 As shown, an engine cylinder head clamp also includes a limiting block 7 and a support rod 8. The limiting block 7 includes two blocks, which are detachably mounted on the base 2 and located on both sides of the cylinder head 1 to limit the cylinder head 1. The support rod 8 is detachably mounted on the base 2 and located at the bottom of the cylinder head 1 to support the cylinder head 1.

[0050] Specifically, before clamping, the two side limit blocks 7 pre-limit the cylinder head 1 on both sides, and together with the bottom support rod 8 to support the weight, achieve "hand-free" pre-positioning, further improving the clamping speed. At the same time, the detachable connection allows it to be adapted to various cylinder heads 1 by replacing the limit blocks 7 and support rods 8 of different heights or widths, making it quick to change types and highly versatile.
