Description

Technical Field

[0001] This utility model relates to the technical field of cylinder head guide press-fitting equipment, specifically a fault-prevention mechanism for press-fitting cast cylinder head guides. Background Technology

[0002] Currently, after machining the combustion chamber air passage in the cylinder head, a guide tube needs to be pressed in. Because the two ends of the guide tube are different, employees may place the guide tube in the wrong direction when placing it, resulting in the guide tube being pressed in the wrong direction, which will lead to the cylinder head being scrapped.

[0003] Therefore, we propose to design a fault-prevention mechanism for press-fitting the guide tube of the cast cylinder head. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A die-fitting mechanism for press-fitting a cast cylinder head guide rod includes a guide rod with a guide rod inlet at the center of its end. A magnet is fixedly connected to the bottom of the guide rod near the guide rod inlet. A limit block is provided at the bottom of the guide rod. A mounting base is embedded and fixedly connected to the top of the guide rod. A ball bearing is provided inside the mounting base. A guide rod body is provided inside the guide rod.

[0007] As a preferred embodiment of the anti-misalignment mechanism for press-fitting a cast cylinder head guide tube according to this utility model, both ends of the top of the limiting block are arc-shaped, corresponding to the ends of the guide tube body.

[0008] As a preferred embodiment of the casting cylinder head guide tube press-fitting error prevention mechanism of this utility model, three mounting seats are provided. One of the three mounting seats corresponds to the position of the magnet, and the center of the other two mounting seats corresponds to the position of the limiting block. When the guide tube body is correctly sent into the guide tube guide rod, the ball in the mounting seat can be pressed upward, thereby further pressing the guide tube body in.

[0009] As a preferred embodiment of the anti-misalignment mechanism for press-fitting a casting cylinder head guide tube according to this utility model, the top of the magnet penetrates the guide tube guide rod and extends into its internal passage. Under the attraction of the magnet, the guide tube body can slide along the bottom of the guide tube guide rod.

[0010] As a preferred embodiment of the casting cylinder head guide tube press-fitting error prevention mechanism described in this utility model, one end of the outer wall of the guide tube body is provided with an angle, and the other end of the guide tube body is provided with a boss. When the guide tube enters the angled part, it is convenient to press the ball upwards, so that after it is put in, it is correctly pressed into the cylinder head.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention effectively prevents the guide tube from being placed in the wrong direction by cooperating with the guide rod, magnet and limiting block, thereby avoiding the guide tube being pressed incorrectly and causing the cylinder head to be scrapped, and greatly improving the product qualification rate.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-4 This utility model provides a casting cylinder head guide tube press-fitting error prevention mechanism, including a guide tube guide rod 1, a guide tube inlet 2 is provided at the center of the end of the guide tube guide rod 1, and a magnet 3 is fixedly connected to the bottom of the guide tube guide rod 1 near the guide tube inlet 2.

[0023] The top of the magnet 3 passes through the guide rod 1 and extends into its internal passage. Under the attraction of the magnet 3, the main body of the catheter 7 can slide along the bottom of the guide rod 1.

[0024] A limiting block 4 is provided at the bottom of the guide rod 1. Both ends of the top of the limiting block 4 are arc-shaped, corresponding to the ends of the main body 7 of the catheter.

[0025] The top of the guide rod 1 is embedded with a mounting base 5, and the mounting base 5 is equipped with a ball bearing 6.

[0026] In this embodiment, three mounting seats 5 are provided. One of the three mounting seats 5 corresponds to the position of the magnet 3, and the center of the other two mounting seats 5 corresponds to the position of the limiting block 4. When the catheter body 7 is correctly sent into the catheter guide rod 1, the ball 6 in the mounting seat 5 can be pressed upward, thereby further pressing the catheter body 7 in.

[0027] The guide rod 1 has a guide body 7 inside. One end of the guide body 7 has an angled outer wall and the other end has a boss. When the angled part enters the guide rod 1, it is easy to press the ball 6 upward and then press it into the cylinder head correctly.

[0028] When in use, place the main body 7 of the guide tube into the guide tube guide rod 1. If the oblique angle is inward first, the guide tube will be inserted along the lower wall under the action of the magnet 3 below. After the oblique angle can go in a little at the position of the limit block 4, it will press the ball 6 upward and thus correctly press it into the cylinder head after it is inserted.

[0029] When the catheter body 7 is placed into the catheter guide rod 1, if the boss goes inward first, the boss will be blocked by the limiting block 4 under the action of the magnet 3 below, and the catheter body 7 will not be able to go in.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
