Description

Technical Field

[0001] This utility model relates to the field of cylinder head processing technology, specifically a combined cylinder head processing fixture. Background Technology

[0002] The cylinder head has a complex structure, including several key parts such as intake and exhaust valve seat holes and valve guide holes, which require high-precision machining to ensure the precise fit and normal operation of each component.

[0003] In related technologies, a search revealed a scheme for a combined fixture for machining automobile engine cylinder heads (publication number CN112959095A). This scheme involves using a wrench to rotate a second worm gear. The second worm gear, in conjunction with a second turbine, drives a drive rod to rotate. When the drive rod rotates, it drives a movable block to move. When the movable block moves, it, in conjunction with a connecting rod, drives a fixed jaw to rotate towards the center, thereby clamping the cylinder head.

[0004] However, the aforementioned clamps that directly contact and clamp the cylinder head will obstruct a part of the cylinder head during use. Since the cylinder head has a complex structure and requires machining of many areas, when machining the side of the cylinder head that contacts the clamp, it is necessary to first bypass the part obstructed by the clamp, then adjust the position of the cylinder head and machine it again. This results in a large number of times the cylinder head needs to be clamped, which affects the machining efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a combined cylinder head machining fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined cylinder head machining fixture, including a rotary driver, which can adjust the position of the cylinder head to facilitate multi-face machining of the cylinder head; an opening plate is mounted on the rotary driver, the opening plate has two rectangular openings, and two pushers are mounted on the back of the opening plate.

[0007] A slide bar, wherein several slide bars are provided and installed on the pusher, a slide block is slidably connected to the slide bar, and a roller is installed on the slide block, the roller being located inside a rectangular opening;

[0008] Two push-pull devices are provided and installed on the back of the perforated plate, and the push-pull devices are connected to the corresponding slides in a transmission manner.

[0009] The pusher controls the roller to clamp the cylinder head through the slide bar and slide block. The pusher controls the rotation of the roller to change the clamping position of the cylinder head. The clamping position can be changed during the clamping process, reducing the number of times the cylinder head needs to be clamped.

[0010] Furthermore, a limiter is installed on the back of the perforated plate. The limiter passes through the perforated plate to restrict the movement of the cylinder head. The limiter includes a first cylinder, and the piston rod of the first cylinder is connected to a stop post. The stop post passes through the perforated plate to ensure that the cylinder head will not move when the position of the cylinder head is adjusted, thus ensuring machining accuracy.

[0011] Furthermore, the pusher includes a fixed plate and a second cylinder mounted on the fixed plate. A pusher seat is mounted on the second cylinder, and a slide bar is connected to the surface of the pusher seat. A slide rail is mounted on the back of the perforated plate, and the pusher seat is slidably connected to the surface of the slide rail. The slide rail can improve the stability of the pusher seat movement and make the clamping of the cylinder head more stable.

[0012] Furthermore, the push-pull device includes an assembly plate, a third cylinder, and a connecting rod assembly. The piston rod of the third cylinder is connected to a slide block. The connecting rod assembly is connected between two corresponding slide blocks and to an opening plate. The connecting rod assembly includes a central rod and two push-pull rods rotatably connected to the central rod. The push-pull rods are rotatably connected to the two corresponding slide blocks. The third cylinder controls the two rollers to roll along the cylinder head through the push-pull rods and the central rod, thereby changing the clamping position.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the cylinder head is placed on the perforated plate, the second cylinder pushes the roller to abut against the cylinder head to achieve cylinder head clamping, the first cylinder pushes the stop column to limit the cylinder head, and when processing the cylinder head, the third cylinder drives the push-pull rod to move through the slide, and the push-pull rod drives the corresponding roller to roll through the center rod. The roller rolls along the cylinder head, which can offset the position of the cylinder head that needs to be processed, reduce the number of times the cylinder head is repeatedly clamped during processing, and improve processing efficiency.

[0018] 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.

[0019] Example:

[0020] Please see Figure 1-3 This utility model provides a technical solution: a combined cylinder head processing fixture, including a rotary driver, which controls the cylinder head to swing, allowing for more flexible cylinder head processing. The rotary driver is equipped with an opening plate 1, which has two rectangular openings. Two pushers are installed on the back of the opening plate 1, and the two pushers control four rollers 7 to clamp the cylinder head.

[0021] Slide bar 14, several slide bars 14 are provided and installed on the pusher, slide block 15 is slidably connected to slide bar 14, and roller 7 is installed on slide block 15. Roller 7 is located in a rectangular opening to provide movement space for roller 7.

[0022] Two push-pull devices are provided and installed on the back of the perforated plate 1. The push-pull devices are connected to the corresponding slides 15. The push-pull devices control the movement of the two corresponding rollers 7 through the slides 15 to realize the position adjustment of the rollers 7.

[0023] The pusher controls the roller 7 to clamp the cylinder head through the slide bar 14 and the slide block 15. The pusher controls the roller 7 to rotate and change the clamping position of the cylinder head. The roller 7 can be offset from the position of the cylinder head that needs to be processed without removing the cylinder head.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, a limiter is installed on the back of the perforated plate 1. The limiter passes through the perforated plate 1 to restrict the movement of the cylinder head, so as to avoid insufficient clamping force of the roller 7 on the cylinder head and help improve the machining accuracy.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the limiter includes a first cylinder 11, and the piston rod of the first cylinder 11 is connected to a stop post 2. The stop post 2 passes through the perforated plate 1 and blocks the side of the cylinder head. When one side of the cylinder head needs to be processed, the first cylinder 11 controls the stop post 2 to move without obstructing the processing of the cylinder head. The stop post 2 can be set into other shapes, such as rectangles or polygons, to better limit the cylinder head.

[0026] In this embodiment, as Figure 1 As shown, the rotary drive includes a mounting base 3, which can be fixed to a designated position. A pneumatic motor 4 is mounted on the mounting base 3. The pneumatic motor 4 is fixedly connected to the perforated plate 1. The pneumatic motor 4 can control the rotation of the cylinder head through the perforated plate 1, which facilitates the processing of different surfaces of the cylinder head.

[0027] In this embodiment, as Figure 2 As shown, the propeller includes a fixed plate 5 and a second cylinder 6 mounted on the fixed plate 5. A propulsion seat 13 is mounted on the second cylinder 6, and a slide bar 14 is connected to the surface of the propulsion seat 13. The second cylinder 6 controls the movement of the slide bar 14 and the parts mounted on the slide bar 14.

[0028] In this embodiment, as Figure 2 As shown, a slide rail 12 is installed on the back of the perforated plate 1, and the push seat 13 is slidably connected to the surface of the slide rail 12. The slide rail 12 can improve the stability and accuracy of the movement of the push seat 13 and prevent loosening.

[0029] In this embodiment, as Figure 2 As shown, the push-pull device includes an assembly plate 8, a third cylinder 9, and a connecting rod assembly. The piston rod of the third cylinder 9 is connected to the slide block 15, and the connecting rod assembly is connected between the two corresponding slide blocks 15 and to the perforated plate 1, so that the third cylinder 9 can control the two rollers 7 to move synchronously.

[0030] In this embodiment, as Figure 2 As shown, the linkage assembly includes a central rod 16 and two push-pull rods 10 rotatably connected to the central rod 16. The push-pull rods 10 are rotatably connected to two corresponding slides 15 to realize the automatic adjustment of the two rollers 7.

[0031] Specifically, during use, the cylinder head is placed in the middle of the perforated plate 1. The first cylinder 11 controls the stop 2 to move to the side of the cylinder head, and the second cylinder 6 pushes the push seat 13 to move. The push seat 13 drives the roller 7 to move through the slide bar 14 and the slide block 15. The roller 7 abuts against the side of the cylinder head to clamp the cylinder head. When machining the cylinder head, the third cylinder 9 controls the slide block 15 to move along the slide bar 14. The slide bar 14 drives another roller 7 to move through the push-pull rod 10 and the center rod 16. The roller 7 can adjust the clamping part on the side of the cylinder head by rolling. During the cylinder head machining process, the machining position of the cylinder head can be flexibly staggered, eliminating the need to repeatedly adjust the cylinder head clamping, reducing the number of adjustments, and improving the machining efficiency of the cylinder head.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
