Description

Technical Field

[0001] This utility model relates to the field of diesel engine cylinder head valve processing technology, specifically a tooling for processing diesel engine cylinder head valves. Background Technology

[0002] The cylinder head is an important component of a diesel engine, located above the cylinder block. It seals the upper part of the cylinder and, together with the cylinder block, forms the combustion chamber. The cylinder head typically has intake and exhaust passages, valve seat holes, valve guide holes, injector mounting holes, cooling water passages, and some lubrication oil passages machined onto it.

[0003] In the machining of valve holes and valve seats in diesel engine cylinder heads, the valve holes typically require vertical machining or angled machining according to design requirements. Most existing machining fixtures can only perform fixed machining at a single angle. When angled machining of valve holes is required, it often necessitates changing the fixture or manually adjusting the positioning, which is complex and inefficient. Furthermore, existing fixtures lack stability when clamping the cylinder head, have limited adjustment range, and are prone to chip accumulation during machining, affecting machining accuracy and efficiency.

[0004] Therefore, it is necessary to design a tooling for machining cylinder head valves of diesel engines to solve the above problems. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Please see Figure 1-3This utility model provides a tooling for machining cylinder head valves of diesel engines, including a fixing plate 3. A device box 5 is fixedly connected to the top of the fixing plate 3, and a first servo motor 15 is fixedly connected to one side of the device box 5. A third rotating shaft 22 is fixedly connected to the output shaft of the device box 5. A connecting shaft 6 is rotatably inserted into one side of the device box 5 via a bearing. Connecting blocks 7 are fixedly inserted into both ends of the connecting shaft 6. Synchronous pulleys 16 are fixedly sleeved on the outer surfaces of both the connecting shaft 6 and the third rotating shaft 22. A synchronous belt 17 is connected to both of the synchronous pulleys 16 through toothed grooves. Two symmetrical adjusting boxes 4 are slidably arranged on the top of the fixed plate 3, and a first rotating shaft 18 is rotatably inserted into one side of each of the two adjusting boxes 4. One end of each of the two insertion blocks 7 is slidably inserted into the interior of the two first rotating shafts 18. A second rotating shaft 19 is rotatably connected to the other side of each of the two adjusting boxes 4, and a bevel gear 10 is fixedly sleeved at one end of each of the second rotating shaft 19 and the first rotating shaft 18 on the same side. The two bevel gears 10 mesh with each other. A rotating sleeve block 9 is fixedly sleeved on the outer surface of each of the two second rotating shafts 19, and an adjusting... Each of the two adjusting blocks 14 has a clamping mechanism on its top. When the two clamping mechanisms clamp the two cylinder heads onto the top of the two adjusting blocks 14, the first servo motor 15 is activated, and the connection of the two synchronous pulleys 16 and a synchronous belt 17 causes the plug-in rotating shaft 6 to rotate, driving the two plug-in blocks 7 to rotate. At this time, the two first rotating shafts 18 follow the rotation of the two plug-in blocks 7, thereby utilizing the two bevel gears 10 inside the two adjusting boxes 4 to allow the two adjusting blocks 14 to rotate on the top of the two adjusting boxes 4. This allows for the machining of valve hole oblique holes when necessary. This allows the two adjusting blocks 14 to rotate synchronously, facilitating the synchronous machining of valve hole oblique holes. During routine vertical valve hole machining, the sliding connection of the two plug-in blocks 7 and the two first rotating shafts 18 enables the rotation of the bidirectional threaded rod 21 to drive the two threaded sleeve blocks 23 to adjust their spacing when the second servo motor 20 is turned on. This allows the two adjusting boxes 4 to adjust the spacing between the two adjusting blocks 14. Simultaneously, the adjustment of the spacing between the two adjusting blocks 14 does not affect their rotation adjustment, allowing for synchronous adjustment and thus improving the efficiency of the device in the overall valve hole machining process.

[0017] To facilitate the adjustment of the distance between the two adjustment boxes 4, thereby adjusting the distance between the two adjustment blocks 14, a second servo motor 20 is fixedly connected to one side of the fixing plate 3. Two symmetrical sliding grooves are opened on the top of the fixing plate 3, and a bidirectional threaded rod 21 is fixedly connected to the output shaft of the second servo motor 20. Threaded sleeve blocks 23 are fixedly sleeved at one end of the bidirectional threaded rod 21 inside the two sliding grooves. The bottoms of the two adjustment boxes 4 are respectively fixedly connected to the tops of the two threaded sleeve blocks 23.

[0018] Furthermore, in order to facilitate the adjustment of the rotation angle of the two adjusting blocks 14 by rotating the two rotating sleeve blocks 9, notches are provided on the top and opposite sides of the two adjusting boxes 4, and the two rotating sleeve blocks 9 are respectively rotatably disposed inside the two notches on the same side, and gaps are formed between the bottom of the two adjusting blocks 14 and the top of the two adjusting boxes 4 respectively.

[0019] Furthermore, to facilitate the clamping of the cylinder head being processed synchronously on the top of the two adjusting blocks 14, the clamping mechanism includes a screw 12, a groove is provided on the top of the adjusting block 14, the screw 12 is rotatably inserted into one side of the adjusting block 14, and a knob 11 is fixedly connected to one end of the screw 12. Both ends of the screw 12 inside the groove are threaded with clamping plates 13, and multiple anti-slip grooves are provided on adjacent sides of the two clamping plates 13.

[0020] To facilitate the installation and height adjustment of the device, and to further adapt the cylinder head machining to the machining tool, a servo electric cylinder 2 is fixedly connected to the bottom of the fixing plate 3, and a base plate 1 is fixedly connected to the bottom of the servo electric cylinder 2, and multiple mounting holes are opened on the outer surface of the base plate 1.

[0021] In order to facilitate the discharge of debris during valve hole machining and avoid debris accumulation affecting cylinder head machining, multiple dust-permeable holes are provided at the bottom of the two adjusting blocks 14, and the two sides of the two threaded sleeve blocks 23 are respectively attached to the two sides of the two sliding grooves.

[0022] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0023] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0024] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
