Description

Technical Field

[0001] The utility model relates to the technical field of metal material processing, in particular to a marking device for signal holes on the side of a flywheel housing. Background Art

[0002] The flywheel housing is an important component in the automotive transmission system. Generally made of cast iron, it has high strength and rigidity and mainly undertakes the functions of power transmission and support. The flywheel housing usually includes a housing and a support plate. The connection between the housing and the support plate is bolted, and this structure can ensure the firmness and reliability of the flywheel housing. During use, the flywheel housing may be damaged due to factors such as heavy load, external force, and irregular vibration.

[0003] As Figure 1 shown, a number of signal holes are equidistantly arranged on the side of the flywheel housing. After being installed on the component, a mark needs to be made directly above the initial signal hole on the front of the flywheel housing. The existing marking devices often have inaccurate marking positions, which affects the subsequent use of the flywheel housing.

[0004] In view of the above problems, it is desirable to provide a marking device for signal holes on the side of a flywheel housing, which can solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a marking device for signal holes on the side of a flywheel housing, which can quickly and accurately mark directly above the first signal hole.

[0006] To achieve the above object of the utility model, a marking device for signal holes on the side of a flywheel housing includes a block, two positioning pins, and a marking member;

[0007] The inner wall of the block is an arc surface structure. The top and bottom of the inner wall of the block both extend forward to form extension areas. An arc-shaped slot is formed between the two extension areas of the block, and the arc-shaped slot is adapted to the flywheel to be marked;

[0008] The two positioning pins are horizontally inserted into the sides of the extension areas at the bottom of the inner wall of the block, and the distance between the two positioning pins is adapted to the distance between two adjacent signal holes of the flywheel to be marked;

[0009] At the top of the block, a through hole is provided directly above the positioning pin corresponding to the first signal hole, and the through hole penetrates the top of the block;

[0010] The marking member includes a cylinder and an end block;

[0011] The cylinder is slidably inserted into the through hole, and the top of the cylinder extends out of the top of the through hole. A mold is provided at the bottom of the cylinder; the end block is fixed to the top of the cylinder.

[0012] Preferably, elastic rubber layers are provided on the inner wall of the extension area and the inner wall of the arc-shaped slot.

[0013] Preferably, a guide body is fixed to the top of the through hole. A guide hole is provided in the guide body. The guide hole communicates with the through hole and shares the same axis. The top of the column extends out of the top of the guide hole, and a spring is sleeved on the part of the column located above the guide hole.

[0014] Further, the spring is a conical spring.

[0015] A flywheel housing side signal hole marking device of the present utility model has the following advantages compared with the prior art:

[0016] (1) Quickly locate the signal hole on the flywheel housing and accurately mark it directly above.

[0017] (2) The structure is simple and the operation is convenient. Description of the Drawings

[0022] The following further describes the present utility model in conjunction with the drawings and specific embodiments.

[0023] As Figure 2 shown, a flywheel housing side signal hole marking device includes a block 1, two positioning pins 2 and a marking member.

[0024] The inner wall of the block 1 is an arc surface structure. The top and bottom of the inner wall of the block 1 both extend forward to form extension areas 3. An arc-shaped slot 4 is formed between the two extension areas 3 of the block 1. The arc-shaped slot 4 is adapted to the flywheel to be marked.

[0025] The two positioning pins 2 are horizontally inserted into the sides of the extension area 3 at the bottom of the inner wall of the block 1, and the distance between the two positioning pins 2 is adapted to the distance between two adjacent signal holes of the flywheel to be marked.

[0026] As Figure 3 shown, at the top of the block 1, a through hole 10 is provided directly above the positioning pin corresponding to the first signal hole, and the through hole 10 penetrates through the top of the block 1; the marking member includes a cylinder 5 and an end block 6; the cylinder 5 is slidably inserted into the through hole, and the top of the cylinder 5 extends out of the top of the through hole, and a mold is provided at the bottom of the cylinder 5; the end block 6 is fixed to the top of the cylinder 5.

[0027] When marking the flywheel housing to be marked, first insert the block 1 into the side of the flywheel housing through the arc-shaped slot 4, and at the same time, the two positioning pins 2 are respectively inserted into the first signal hole and the second signal hole of the flywheel housing. When the two positioning pins 2 cannot be inserted, it means that the signal hole position of the flywheel housing is incorrectly machined and needs to be reworked; when the two positioning pins 2 are just inserted into the first signal hole and the second signal hole, start the external hydraulic device to press the end block 6 on the cylinder 5, and the mold at the bottom of the cylinder 5 makes a mark on the flywheel housing directly above the first signal hole.

[0028] In this embodiment, elastic rubber layers are provided on the inner wall of the extension area 3 and the inner wall of the arc-shaped slot 4, effectively avoiding rigid contact with the flywheel housing.

[0029] In this embodiment, as Figure 3 and Figure 4 shown, a guide body 7 is fixed to the top of the through hole, a guide hole 8 is provided in the guide body 7, the guide hole 8 is communicated with the through hole 10 and shares the same axis, the top of the cylinder 5 extends out of the top of the guide hole 8, and a spring 9 is sleeved on the part of the cylinder 5 above the guide hole 8; with such a setting, on the one hand, it effectively prevents the cylinder 5 from deviating during marking, and on the other hand, after marking is completed, under the elastic force of the spring 9, the cylinder 5 will move upward to restore its original state.

[0030] Furthermore, in this embodiment, the spring 9 is a pagoda-shaped spring. In the same installation space, a pagoda-shaped spring of the same volume can bear greater pressure than an ordinary compression spring, and correspondingly can store more energy, and can bear greater pressure under the same deformation amount.

[0031] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
