Description

Technical Field

[0001] This utility model relates to the field of edge and corner treatment devices, specifically an edge and corner treatment device for engine gaskets. Background Technology

[0002] Engine gaskets, especially cylinder head gaskets, are crucial components of an engine. Their primary function is to ensure a tight seal at the cylinder head and cylinder block mating surfaces, preventing air leakage from the cylinder head and water jacket leakage from the water jacket. Located between the engine cover and the engine block, the engine gasket fills the microscopic gaps between them, ensuring a sealed combustion chamber. It needs sufficient strength, pressure resistance, heat resistance, and corrosion resistance, while also possessing a degree of elasticity to compensate for the roughness and unevenness of the top surface of the engine block and the bottom surface of the engine cover. Rubber engine gaskets require the removal of burrs from their edges after production.

[0003] Currently, the edge treatment of existing rubber engine gaskets mostly involves manual scraping with a knife and machine grinding. Manual scraping is inconsistent and can easily damage the engine gasket, while machine grinding is costly and requires a clamp to hold the engine gasket in place, which is time-consuming, resulting in low processing efficiency for engine gaskets. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an edge and corner treatment device for engine gaskets, so as to solve the technical problem of low effect and efficiency of general edge and corner treatment devices in treating the edge and corner of engine gaskets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an edge treatment device for an engine liner, comprising a base and a lifting plate disposed above the base, wherein a lower mold is embedded and fixed in the base, and an engine liner positioning groove is provided at the top of the lower mold; an upper mold is detachably fixed at the bottom of the lifting plate, and a cutting blade corresponding to the engine liner positioning groove is fixed at the bottom of the upper mold; and connecting rods are fixed on both sides of the top surface of the upper mold, and positioning pins that abut against the top surface of the lifting plate are elastically provided on both sides of the outer wall of the connecting rods.

[0006] The present invention is further configured such that grooves are symmetrically provided at both ends of the base, and internal hexagon bolts that are threaded into the lower mold are embedded in the grooves.

[0007] The present invention is further provided that a support frame is provided at the top of the base, and fastening bolts threaded into the base are installed at both ends of the support frame.

[0008] The present invention is further configured such that a hydraulic rod is installed at the top of the support frame, and positioning rods that are slidably inserted into the support frame are fixed on both sides of the top surface of the lifting plate.

[0009] The present invention is further configured such that a push rod is fixed at the center of the top surface of the lifting plate, and the bottom end of the hydraulic rod is fixedly connected to the push rod.

[0010] The present invention is further configured such that both ends of the lifting plate are provided with connecting holes, the connecting rod is inserted into the connecting holes, and the end of the connecting rod passing through the connecting hole is symmetrically provided with mounting grooves.

[0011] The present invention is further configured such that the positioning pin is slidably inserted into the mounting groove, and a spring that abuts against the positioning pin is embedded in the mounting groove.

[0012] In summary, this utility model has the following advantages: By fixing a lower mold and an upper mold to the base and lifting plate respectively, the gasket is fitted into the engine gasket positioning groove during edge treatment. Excess edges of the gasket protrude from the top of the upper mold. A hydraulic rod drives the lifting plate and upper mold downwards via a push rod, allowing the cutting blade at the bottom of the upper mold to cut the edges, facilitating gasket positioning and improving the accuracy and efficiency of edge treatment. The lower mold can be easily disassembled and replaced by unscrewing the hexagonal bolts. Simultaneously, the positioning pin is squeezed from the side wall of the lifting plate, causing it to retract into the mounting groove, thus separating the connecting rod from the connecting hole. The corresponding mold can be replaced according to the gasket shape. The connecting rod at the top of the upper mold is inserted into the connecting hole, tightly connecting the top of the upper mold to the lifting plate. Springs in the mounting grooves at both ends of the connecting rod push the positioning pin against the top of the lifting plate, thus fixing the upper mold to the lifting plate and improving the convenience of mold replacement. This invention is suitable for edge treatment of different types of gaskets. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] An edge treatment device for an engine gasket, such as Figure 1-4 As shown, the device includes a base 1 and a lifting plate 6 disposed above the base 1. A lower mold 8 is embedded and fixed in the base 1. An engine liner positioning groove 10 is opened at the top of the lower mold 8. An upper mold 2 is detachably fixed at the bottom of the lifting plate 6. A cutting blade 12 corresponding to the engine liner positioning groove 10 is fixed at the bottom of the upper mold 2. Connecting rods 15 are fixed on both sides of the top surface of the upper mold 2. Positioning pins 18 that abut against the top surface of the lifting plate 6 are elastically provided on both sides of the outer wall of the connecting rods 15.

[0020] Both ends of the base 1 are symmetrically provided with grooves 9, and hexagon socket head cap screws 11 are embedded in the grooves 9 and threaded into the lower mold 8. The top of the base 1 is provided with a support frame 3, and both ends of the support frame 3 are provided with fastening bolts 7 threaded into the base 1. The top of the support frame 3 is provided with a hydraulic rod 5. The top surface of the lifting plate 6 is fixed with positioning rods 4 that are slidably inserted into the support frame 3. When the edge of the gasket is processed, it is fitted into the positioning groove 10 of the engine gasket. The excess edge of the gasket protrudes from the top of the upper mold 2. The hydraulic rod 5 drives the lifting plate 6 and the upper mold 2 to move downward through the push rod 13, so that the cutting blade 12 at the bottom of the upper mold 2 can cut the edge. The lower mold 8 and the upper mold 2 are both made of soft materials such as rubber, so that they will not obstruct the movement of the cutting blade 12.

[0021] Furthermore, a push rod 13 is fixed at the center of the top surface of the lifting plate 6. The bottom end of the hydraulic rod 5 is fixedly connected to the push rod 13. Both ends of the lifting plate 6 are provided with connection holes 14. The connecting rod 15 is inserted into the connection hole 14. The end of the connecting rod 15 that passes through the connection hole 14 is symmetrically provided with an installation groove 17. The positioning pin 18 is slidably inserted into the installation groove 17. The installation groove 17 is embedded with a spring 16 that abuts against the positioning pin 18. After unscrewing the hexagonal bolt 11, the lower mold 8 is disassembled and replaced. At the same time, the positioning pin 18 is squeezed from the side wall of the lifting plate 6 to retract into the installation groove 17, thereby separating the connecting rod 15 from the connection hole 14. The mold corresponding to the shape of the liner is replaced. The connecting rod 15 at the top of the upper mold 2 is inserted into the connection hole 14. The top of the upper mold 2 is tightly connected to the lifting plate 6. The springs 16 in the installation grooves 17 at both ends of the connecting rod 15 push the positioning pin 18 to abut against the top of the lifting plate 6, thereby keeping the upper mold 2 and the lifting plate 6 fixed.

[0022] The working principle of this utility model is as follows: When the gasket is processed at the edges and corners, it is fitted into the engine gasket positioning groove 10. The excess edges and corners of the gasket protrude from the top of the upper mold 2. The hydraulic rod 5 drives the lifting plate 6 and the upper mold 2 to move downward through the push rod 13, so that the cutting blade 12 at the bottom of the upper mold 2 cuts the edges and corners and positions the gasket, improving the accuracy and efficiency of the gasket edge and corner processing. When processing different types of gaskets, the lower mold 8 can be disassembled and replaced after unscrewing the hex bolt 11. At the same time, the positioning pin 18 is squeezed from the side wall of the lifting plate 6 and retracted into the mounting groove 17, so that the connecting rod 15 is separated from the connecting hole 14. The corresponding mold is replaced according to the shape of the gasket. The connecting rod 15 at the top of the upper mold 2 is inserted into the connecting hole 14, and the top of the upper mold 2 is tightly connected to the lifting plate 6. The springs 16 in the mounting grooves 17 at both ends of the connecting rod 15 push the positioning pin 18 to abut against the top of the lifting plate 6, so that the upper mold 2 and the lifting plate 6 are fixed, improving the convenience of mold replacement.
