DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figures 1 to 5 As shown, a production fixture device for processing an engine cylinder head provided in this embodiment includes a mounting frame 1, a fixing plate 4 is fixedly installed on the surface of the mounting frame 1, fixing frames 6 are fixedly installed on both sides of the fixing plate 4, a motor 8 is installed inside the fixing frame 6, a mounting plate 7 is connected between the motors 8, support blocks 10 are fixedly installed on the surfaces of both sides of the mounting plate 7, a fixing rod 14 is arranged between every two adjacent support blocks 10, a moving rod 17 is symmetrically arranged between the two fixing rods 14, a clamping hole 16 is opened on the surface of the moving rod 17, moving seats 19 are sleeved on both ends of the moving rod 17, a fixing block 21 is installed on the upper end of the moving seat 19, a rotating disk 15 is movably installed on the surface of the fixing block 21, a spring telescopic rod 20 is symmetrically arranged on the surface of the rotating disk 15, and an extrusion plate 11 is fixedly arranged on the surface of the spring telescopic rod 20.

[0027] Among them, under the action of the motor 21, the motor 21 drives the mounting plate 7 to rotate, thereby playing a rotating role in the engine cylinder head processing, improving the flexibility of the engine cylinder head processing, and further, under the action of the rotating disk 15, the spring telescopic rod 20 and the extrusion plate 11 can be rotated, and the extrusion plate 11 is stretched by the spring telescopic rod 20. When the cylinder head is placed on the surface of the mounting plate 7, the spring telescopic rod 20 is used to rebound and drive the extrusion plate 11 to descend to clamp and fix the engine cylinder head.

[0028] In this embodiment, if Figure 4 and Figure 5As shown, the present embodiment provides a production fixture device for processing an engine cylinder head, wherein a mounting seat 18 is installed at the lower end of a movable seat 19, a clamping rod 22 is movably inserted inside the mounting seat 18 and penetrates into the movable seat 19, the upper end of the clamping rod 22 is inserted into the clamping hole 16, a limiting block 24 is installed on the surface of the clamping rod 22, a return spring 23 is sleeved on the surface of the clamping rod 22, the return spring 23 is located between the lower end of the limiting block 24 and the mounting seat 18, the lower end of the clamping rod 22 penetrates into the lower end surface of the mounting seat 18, and a pulling block is provided at the lower end of the clamping rod 22.

[0029] Among them, by pulling the clamping block, the movable seat 19 slides on the movable rod 17. When it cannot move to the appropriate clamping hole 16, the reset spring 23 will drive the clamping rod 17 to retract downward, and the limit block 24 limits the reset spring 23. When it moves to the appropriate clamping hole 16, the reset spring 23 will drive the upper end of the clamping rod 17 into the clamping hole 16, forming a fixing effect, thereby selecting the processing position of the engine cylinder head and improving the accuracy.

[0030] In this embodiment, if Figure 1 As shown, this embodiment provides a production fixture device for processing an engine cylinder head, wherein slide rails 2 are provided on both sides of the upper end of a mounting frame 1, a slide rod 3 is installed inside the slide rail 2, both ends of the slide rod 3 are connected to the slide rail 2, a hydraulic rod is fixedly installed on the upper end of the slide rod 3, and a fixture mechanism 5 for clamping and conveying the cylinder head is provided at the lower end of the hydraulic rod.

[0031] Among them, under the action of the connection between the slide rod 3 and the slide rail 2, the slide rod 3 drives the hydraulic cylinder to move. At the same time, under the action of the hydraulic rod, the clamping mechanism 5 can adjust the position up and down during the process of clamping the conveying cylinder cover.

[0032] In this embodiment, if Figure 3 As shown, this embodiment provides a production fixture device for processing an engine cylinder head, wherein a coupling 9 is provided at the output end of a motor 8, and the coupling 9 is connected to a mounting plate 7 at a side away from the motor 8, and a rubber pad 12 is provided on the surface of the mounting plate 7, and support plates for connecting to the coupling 9 are provided on both sides of the mounting plate 7, and the support plates are L-shaped.

[0033] Among them, by using the coupling 9 to connect the motor 8, the faults caused by the wear and vibration of the motor 8 due to errors can be greatly reduced, thereby improving the efficiency of the motor 8 driving the mounting plate 7 to rotate. At the same time, when the cylinder head is placed on the surface of the mounting plate 7 through the clamp mechanism 5, under the action of the rubber pad 12, the friction between the two will be enhanced, and the engine cylinder head will be better fixed. Under the action of the support plate, the mounting plate 7 has a fixing effect and its stability is enhanced.

[0034] like Figures 1 to 5As shown, the principle of a production fixture device for processing an engine cylinder head provided in this embodiment is as follows: under the action of the motor 21, the motor 21 drives the mounting plate 7 to rotate, thereby playing a rotating role in the processing of the engine cylinder head, improving the flexibility of the processing of the engine cylinder head, and further, under the action of the rotating disk 15, the spring telescopic rod 20 and the extrusion plate 11 can be rotated, and the extrusion plate 11 is driven to stretch by the spring telescopic rod 20. When the cylinder head is placed on the surface of the mounting plate 7, the spring telescopic rod 20 is used to rebound and drive the extrusion plate 11 to descend to clamp and fix the engine cylinder head, and by pulling the clamping block, the movable seat 1 9 slides on the moving rod 17. When it cannot move to the appropriate clamping hole 16, the reset spring 23 will drive the clamping rod 17 to retract downward. The limit block 24 limits the reset spring 23. When it moves to the appropriate clamping hole 16, the reset spring 23 will drive the upper end of the clamping rod 17 to enter the clamping hole 16 to form a fixing effect, thereby selecting the processing position of the engine cylinder head and improving the accuracy. Moreover, under the action of the connection between the sliding rod 3 and the sliding rail 2, the sliding rod 3 drives the hydraulic cylinder to move. At the same time, under the action of the hydraulic rod, the clamping mechanism 5 can adjust the upward and downward extension of the clamping mechanism 5 in the process of clamping and conveying the cylinder head.

[0035] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0036] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0037] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
