Abstract
Description
Technical Field
[0001] This invention relates to a tooling fixture, specifically to a tool for removing burrs from the water passage opening of a cylinder head. Background Technology
[0002] Currently, in the aluminum alloy casting industry, the water channel structure of automobile engine cylinder heads (especially exhaust integrated cylinder heads) consists of upper, middle and lower water channels. The gap of the water channel sand core used in casting is not easy to control, resulting in complex and difficult-to-clean burrs at the cylinder head water channel openings. Cleaning the parting flash burrs at the cylinder head water channel openings is quite difficult. Operators continuously use hammers or chisels for manual work, which results in long cleaning cycles, high labor intensity and poor cleaning effect. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a tool for removing burrs from cylinder head water passages that is easy to clean and allows for the rapid and complete removal of burrs.
[0004] The objective of this invention is achieved by the following technical solution: a tool for removing burrs from the parting edge of a cylinder head water passage, comprising a handle and a sleeve, wherein the handle is movably connected within the sleeve, the other end of the handle is connected to a clamping head, a pin connecting rod is mounted on the upper part of the clamping head, a positioning boss is provided on the lower part of the clamping head, and a burr groove is provided at the bottom of the clamping head.
[0005] The pin connecting rod has a straight "I" shape and is perpendicular to the clamp head. The positioning boss has an arc shape and is located on both sides of the clamp head. The burr groove has a cross shape.
[0006] With the structure of this invention, the burr groove at the bottom of the clamp head is vertically inserted into the burr part of the cylinder head water passage. The insertion depth is positioned by the positioning boss. Then, using the lever principle, the pin connecting rod is rotated, so that the burr of the water passage is completely removed by rapid rotation. This solves the problems of low work efficiency and high labor intensity for operators, reduces labor intensity, is fast and simple, improves cleaning efficiency, is easy to use, has a long service life, and effectively eliminates the safety hazards of using hammers or chisels for cleaning. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of the structure of the parting burr removal tool for the cylinder head water passage of the present invention.
[0008] Figure 2 This is a schematic diagram illustrating the application of the present invention to the removal of parting burrs from the cylinder head water passage. Detailed Implementation
[0009] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0010] Reference Figure 1 As can be seen, the cylinder head water passage parting burr removal tool of the present invention includes a handle 1 and a sleeve 2. The handle 1 is fitted inside the sleeve 2 and is movably connected (the handle is rotatable inside, and the sleeve is fixed outside). The other end of the handle 1 is connected to a clamp 4 (the handle and the clamp can rotate simultaneously). A pin connecting rod 3 is installed on the upper part of the clamp 4, a positioning boss 5 is provided on the lower part of the clamp 4, and a burr groove 6 is provided at the bottom of the clamp 4. One end of the handle 1 faces the operator.
[0011] The pin connecting rod 3 has an "I"-shaped structure and is perpendicular to the clamp head 4 (the pin connecting rod 3 is horizontally positioned, while the clamp head and sleeve are vertically positioned). The pin connecting rod can be moved to the left (counterclockwise) or right (clockwise) to adjust the rotation direction of the clamp head. The positioning boss 5 has an arc-shaped structure and is located on both sides of the clamp head 4 (there is a certain distance between the positioning bosses on both sides) to prevent the clamp head from being inserted too deeply into the cylinder head water passage, which would make it difficult to control and provide a good positioning function. The burr groove 6 has a "+"-shaped structure to easily hold the parting burrs of the cylinder head water passage.
[0012] like Figure 1 , Figure 2 As shown, first align the burr groove 6 at the bottom of the chuck 4 with the burr part 7 of the water passage opening of the cylinder head 8 (especially the exhaust integrated cylinder head). Then insert the chuck until the positioning boss 5 fits against the cylinder head water passage opening. The burr groove 6 holds the parting flash burr of the cylinder head water passage opening. Then hold the sleeve 2 with your left hand and the right end of the pin connecting rod 3 with your right hand. Then rotate the pin connecting rod clockwise. The parting flash burr of the cylinder head water passage opening will rotate quickly with the burr groove 6 at the bottom of the chuck, thereby quickly cleaning and removing the burr. The whole process has a short cleaning cycle and excellent cleaning effect.
