Description

Technical Field

[0001] The utility model relates to a field, in particular to an adapting fixture for machining a cylinder cover of an automobile engine. Background Art

[0002] During the production process of automobile engine cylinder heads, some parts need to be installed on the outer surface of the cylinder heads of automobile engines. In order to prevent the automobile engine cylinder heads from being displaced during the processing, fixtures are used to clamp them.

[0003] The existing fixtures for machining automobile engine cylinder heads have the problem that it is inconvenient to change the height between the fixture and the engine cylinder head;

[0004] The reason for this problem is that during the processing of the automobile engine cylinder head, other parts need to be installed on the outer surface of the automobile engine cylinder head. At this time, a fixture is needed to clamp the automobile engine cylinder head to prevent the automobile engine cylinder head from being displaced during the processing. There are many positions that need to be processed on the automobile engine cylinder head. Some processing points are at the top of the automobile engine cylinder head, and some are at the bottom of the automobile engine cylinder head. At this time, workers have to squat or stand up constantly while processing the automobile engine cylinder head. This not only affects the processing efficiency of the automobile engine cylinder head, but also increases the unnecessary labor generated by workers when processing the automobile engine cylinder head. Therefore, we propose an adaptation fixture for processing automobile engine cylinder heads. Utility Model Content

[0005] The utility model aims to provide an adapting fixture for machining an automobile engine cylinder head, so as to solve the problem that during the existing automobile engine cylinder head machining, the machining height cannot be adjusted and the workers need to squat or stand up continuously.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An adapting fixture for machining a cylinder head of an automobile engine comprises a workbench and a cylinder head fixture. The top surface of the workbench is provided with a lifting plate, and the cylinder head fixture is arranged on the top surface of the lifting plate.

[0008] The automobile engine cylinder head is placed above the lifting plate, and then the cylinder head clamp is used to clamp the automobile engine cylinder head. The height position of the cylinder head clamp can be adjusted according to the processing position of the automobile engine cylinder head by lifting the lifting plate, which makes it convenient for workers to use the cylinder head clamp and improves the processing efficiency of the automobile engine cylinder head.

[0009] As a further preference of the present invention, the cylinder head clamp on the top surface of the lifting plate includes three sets of hydraulic clamping mechanisms, which are respectively arranged on the left side, right side and rear end of the top surface of the lifting plate, and the position between the three sets of hydraulic clamping mechanisms is the cylinder head processing position.

[0010] Through the clamping of three sets of hydraulic clamping mechanisms, the engine cylinder head can be stably clamped at the cylinder head processing position.

[0011] As a further preferred embodiment of the present invention, a cylinder cover sliding mechanism is also provided in the middle of the top surface of the lifting plate.

[0012] When placing the cylinder head, do not place it directly on the cylinder head processing position, because if it is placed directly, it is very likely to hit the cylinder head clamp and cause damage to both the engine cylinder head and the cylinder head clamp. In order to avoid this situation, a cylinder head sliding mechanism is set up, and the cylinder head is placed on the cylinder head sliding mechanism, and then the engine cylinder head is transported to the cylinder head processing position through the cylinder head sliding mechanism, which can effectively avoid the occurrence of the above situation.

[0013] As a further preferred embodiment of the present invention, the cylinder cover sliding mechanism comprises sliding rails and sliding plates, the sliding rails are arranged in parallel, and two sides of the sliding plate are slidably connected to the sliding rails.

[0014] As a further preferred embodiment of the present invention, the top surface of the lifting plate is further provided with a limiting enclosure plate, and the limiting enclosure plate is located on both sides and the rear end of the slide rail.

[0015] It plays a limiting role to prevent the engine cylinder head from being damaged.

[0016] As a further preferred embodiment of the present invention, a lifting hydraulic rod is connected to the center of the bottom surface of the lifting plate, and a hydraulic cylinder is connected to the lower end of the lifting hydraulic rod.

[0017] Arranging a lifting hydraulic rod at the center of the bottom surface of the lifting plate can play a good supporting role. The lifting hydraulic rod can be raised or lowered by controlling the hydraulic cylinder, so that the lifting and lowering of the lifting plate can be indirectly controlled.

[0018] As a further preferred embodiment of the present invention, support rods are provided at the four corners of the bottom surface of the workbench, a support plate is horizontally provided in the middle of the support rods, a pad is provided in the middle of the top surface of the support plate, and the top of the pad is connected to the hydraulic cylinder.

[0019] As a further preferred embodiment of the present invention, a "U"-shaped limiting structure is further provided on both sides of the bottom surface of the lifting plate, and the vertical section of the "U"-shaped limiting structure passes downward through the workbench and is slidably connected to the workbench.

[0020] The "U"-shaped limit structure plays a role in limiting and guiding during lifting.

[0021] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:

[0022] 1. Place the automobile engine cylinder head on the upper position of the lifting plate, and then use the cylinder head clamp to clamp the automobile engine cylinder head. The height position of the cylinder head clamp can be adjusted according to the processing position of the automobile engine cylinder head by lifting the lifting plate, which is convenient for workers to use the cylinder head clamp and improves the processing efficiency of the automobile engine cylinder head.

[0023] 2. Through the clamping of three sets of hydraulic clamping mechanisms, the engine cylinder head can be stably clamped at the cylinder head processing position.

[0024] 3. When placing the cylinder head, do not place it directly on the cylinder head processing position, because if it is placed directly, it is very likely to hit the cylinder head fixture and cause damage to both the engine cylinder head and the cylinder head fixture. In order to avoid this situation, a cylinder head sliding mechanism is set up, and the cylinder head is placed on the cylinder head sliding mechanism, and then the engine cylinder head is transported to the cylinder head processing position through the cylinder head sliding mechanism, which can effectively avoid the occurrence of the above situation.

[0025] 4. Setting a lifting hydraulic rod at the center of the bottom surface of the lifting plate can play a good supporting role. The lifting hydraulic rod can be raised or lowered by controlling the hydraulic cylinder, so that the lifting and lowering of the lifting plate can be indirectly controlled.

[0026] 5. The "U"-shaped limit structure plays a role in limiting and guiding during lifting. BRIEF DESCRIPTION OF THE DRAWINGS
