Description

Technical Field

[0001] This utility model relates to the technical field of cylinder head repair equipment, specifically to a cylinder head repair device for an electric spark welding machine. Background Technology

[0002] With the continuous development of industrial manufacturing, many equipment and mechanical parts inevitably experience wear or damage during long-term use, especially high-precision mechanical components such as cylinder heads. As a key component in automobiles and construction machinery, the cylinder head, due to its special working environment, often suffers from corrosion, wear, and deformation, affecting the normal operation of the equipment. To ensure the service life and performance of the cylinder head, repair is often necessary. Currently, electric spark welding technology is widely used in the field of metal surface repair. Its advantages lie in its ability to precisely repair metal surfaces and generate almost no thermal stress during the repair process, thus avoiding the problem of thermal deformation. Electric spark welding technology uses high-frequency electric sparks to precisely deposit repair material onto the damaged metal surface, restoring the function and performance of the component. It has high repair precision and is widely used in the repair of precision components such as cylinder heads.

[0003] However, existing EDM (Electrical Discharge Machining) machines typically use clamping mechanisms to fix the cylinder head to the worktable surface during the repair process. While this method ensures the stability of the cylinder head to some extent, the operation remains quite cumbersome when repairing multiple sides of the cylinder head. Specifically, to repair other sides of the cylinder head, the operator needs to manually flip the cylinder head and re-fix it. This not only increases the complexity of the operation, but the frequent manual flipping also increases the operator's labor intensity and operation time, reducing work efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cylinder head repair device for an electric spark surfacing machine. It solves the problem that when repairing other surfaces of the cylinder head using the clamping mechanism of the existing electric spark surfacing machine, the operator needs to manually flip the cylinder head and re-fix it. This not only increases the complexity of the operation, but also increases the labor intensity and operation time of the operator due to the frequent manual flipping, thus reducing work efficiency.

[0018] For example, in a cylinder head repair device for an electric spark welding machine provided in at least one embodiment of the present invention, rollers are fixed on both the front and rear sides of the bottom wall of the vertical plate, and the rollers are rolled in the corresponding grooves.

[0019] For example, in a cylinder head repair device for an electric spark welding machine provided in at least one embodiment of the present invention, the fixing component includes a C-shaped frame, the C-shaped frame is rotatably mounted on the side wall of the vertical plate, the length of the bottom plate of the C-shaped frame is greater than the length of its top plate, and a threaded knob is screwed through the top plate of the C-shaped frame.

[0020] A pressure plate is rotatably mounted on the bottom of the threaded knob.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] like Figures 1-2 As shown, it illustrates a cylinder head repair device for an electric spark surfacing machine according to an embodiment of the present invention, including an electric spark surfacing machine body 1, and further comprising:

[0044] The movable component 3 is fixed on the worktable of the electric spark surfacing machine body 1, and an mounting plate 4 is installed above the movable component 3.

[0045] There are two vertical plates 6. The two vertical plates 6 are mounted on the mounting plate 4 by clamping components 5. The top of the two vertical plates 6 on the side that is close to each other is rotatably mounted with fixing components 10.

[0046] Rotating component 11 is installed on the outer wall of one side vertical plate 6 and is used to control the rotation of fixed component 10.

[0047] A side door 2 is rotatably installed at the front end of the electric spark welding machine body 1 corresponding to the welding position, and an electric welding lens 12 is installed on the side door 2.

[0048] In some examples, the clamping component 5, in conjunction with the fixing component 10 on the vertical plate 6, clamps and fixes the cylinder head to be processed. Simultaneously, the moving component 3 controls the forward, backward, left, and right movement of the clamped cylinder head, allowing for repair operations on the cylinder head in conjunction with the EDM welding machine body 1. Furthermore, the rotating component 11 can rotate the clamped cylinder head to allow for repair operations on other surfaces of the cylinder head without manual rotation, making operation simple and convenient. The side door 2 facilitates placing the cylinder head on or removing it from the worktable of the EDM welding machine body 1. The welding lens 12 prevents the welding light from injuring the operator's eyes and allows the operator to easily observe the repair progress.

[0049] For example, such as Figure 3 As shown, the moving component 3 includes a mounting frame 31, which is fixed on the worktable of the electric spark welding machine body 1. A first electric guide rail 32 is fixed on the front and rear side walls of the inner cavity of the mounting frame 31, and a second electric guide rail 33 is fixed on the left and right side walls of the inner cavity of the mounting frame 31. A mounting block 36 is slidably installed inside the mounting frame 31.

[0050] A longitudinal shaft 34 is fixed between the sidewalls of the sliders on the two No. 1 electric guide rails 32;

[0051] A horizontal shaft 35 is fixed between the sidewalls of the sliders on the two No. 2 electric guide rails 33;

[0052] The vertical axis 34 and the horizontal axis 35 are vertically arranged, and both the vertical axis 34 and the horizontal axis 35 slide through the mounting block 36;

[0053] The top wall of mounting block 36 is fixedly connected to the bottom wall of mounting plate 4.

[0054] In some examples, the movable component 3 can control the forward, backward, left, and right movement of the clamped cylinder head, working in conjunction with the electric spark surfacing machine body 1 to perform repair operations on the cylinder head. When it is necessary to control the movement of the cylinder head, the slider on the first electric guide rail 32 is controlled to move the longitudinal axis 34 left and right, thereby moving the cylinder head left and right. The slider on the second electric guide rail 33 is controlled to move the transverse axis 35 forward and backward, thereby moving the cylinder head forward and backward.

[0055] For example, such as Figure 4 As shown, the clamping assembly 5 includes a bidirectional screw 51, which is rotatably mounted on the mounting plate 4. Sliding blocks 52 are screwed to both ends of the bidirectional screw 51.

[0056] The sliding block 52 is fixed to the bottom wall of the vertical plate 6;

[0057] A motor 53 is fixed to one side of the mounting plate 4, and the power shaft of the motor 53 is fixedly connected to one end of the bidirectional screw 51.

[0058] A sliding groove 7 is provided in the middle of the top wall of the mounting plate 4, and rolling grooves 9 are provided on the front and rear sides of the top wall of the mounting plate 4. A bidirectional screw 51 is rotatably installed in the sliding groove 7, and a sliding block 52 is slidably installed in the sliding groove 7. The power shaft of the No. 1 motor 53 passes through the side wall of the sliding groove 7 through a bearing.

[0059] Rollers 8 are fixed on both the front and rear sides of the bottom wall of the vertical plate 6, and the rollers 8 are rolled in the corresponding grooves 9.

[0060] In some examples, the clamping assembly 5, in conjunction with the fixing assembly 10 on the vertical plate 6, clamps and fixes the cylinder head to be processed. When the cylinder head needs to be clamped, the first motor 53 is controlled to operate, driving the bidirectional screw 51 to rotate. During the rotation of the bidirectional screw 51, the sliding blocks 52 on both sides move closer together, thereby causing the vertical plates 6 on both sides to move closer together, and causing the fixing assembly 10 to clamp the cylinder head. The rollers 8 provide support for both sides of the vertical plate 6 and reduce friction with the mounting plate 4 during the movement of the vertical plate 6.

[0061] For example, such as Figure 5 As shown, the fixing component 10 includes a C-shaped frame 101, which is rotatably mounted on the side wall of the vertical plate 6. The length of the bottom plate of the C-shaped frame 101 is greater than the length of its top plate, and a threaded knob 102 is screwed through the top plate of the C-shaped frame 101.

[0062] A pressure plate 103 is rotatably mounted on the bottom end of the threaded knob 102.

[0063] The rotating assembly 11 includes a mounting shell 111, which is fixed to the outer wall of a vertical plate 6 on one side. A mounting shaft 112 is rotatably mounted inside the mounting shell 111, and a second motor 115 is fixed to the bottom wall of the mounting shell 111.

[0064] One end of the mounting shaft 112 passes through the vertical plate 6 via a bearing and is fixedly connected to the side wall of the C-shaped frame 101. A worm gear 113 is fixed on the shaft of the mounting shaft 112.

[0065] Worm gear 113 is meshed with worm 114;

[0066] The worm gear 114 is rotatably mounted between the inner walls of the mounting housing 111;

[0067] The power shaft of motor 115 passes through the bottom wall of mounting housing 111 via a bearing and is fixedly connected to the bottom end of worm gear 114.

[0068] In some examples, a fixing component 10 is used to clamp and fix the cylinder head to be processed. A rotating component 11 can rotate the clamped cylinder head to achieve repair operations on other surfaces of the cylinder head without manual rotation, making the operation simple and convenient. When clamping and fixing the cylinder head, the clamping component 5 is used to initially bring the vertical plates 6 on both sides closer together until the cylinder head can be mounted on the base plate of the C-shaped frame 101. The clamping component 5 is then used to control the vertical plates 6 on both sides to move closer together until the side wall of the C-shaped frame 101 is tightly attached to the side wall of the cylinder head. The threaded knob 102 is rotated, and during the rotation of the threaded knob 102, the pressure plate 103 is moved down until the pressure plate 103 is tightly attached to the top wall of the cylinder head, thus completing the clamping and fixing of the cylinder head. When other surfaces of the cylinder head need to be repaired, the second motor 115 is controlled to rotate. The second motor 115 drives the worm wheel 113 to rotate through the worm 114. During the rotation of the worm wheel 113, the C-shaped frame 101 is driven to rotate through the mounting shaft 112, thereby causing the cylinder head to flip over for maintenance.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
