Description

Technical Field

[0001] The invention relates to the technical field of engine assembly tools, in particular to a tool for installing an oil dipstick sleeve. Background Art

[0002] Because a part of the engine oil dipstick sleeve needs to be driven into the cylinder body, the current method of assembling the engine oil dipstick sleeve is: the production worker first gently knocks the oil dipstick sleeve onto the engine cylinder body with a hammer, and then uses an iron rod longer than the oil dipstick sleeve to push against the step of the oil dipstick sleeve, and hammers with a hammer until the part of the sleeve that needs to be driven in is completely driven into the cylinder body. Because the step on the oil dipstick sleeve is only about 1 cm wide, when using the iron rod to knock, it is often necessary to replace the knocking surface to ensure that the sleeve will not deviate in a certain direction. In addition, because the sleeve and the iron rod are fixed with one hand, and the two are two separate objects, the production workers have high labor intensity, difficult operation, low assembly efficiency, and serious impact on production rhythm.

[0031] Example

[0032] See also Figure 1-5 The present invention provides a technical solution: a tool for installing an oil dipstick sleeve, including a tool body 10.

[0033] See also Figure 2 , 3 The tool body 10 includes a round tube 110 and an oil dipstick sleeve 160. A striking surface 120 is fixed on the top of the round tube 110. The top surface of the striking surface 120 is a square plane, which increases the striking area and is convenient for accurately striking on the striking surface 120, effectively improving the striking accuracy and the production efficiency. A sleeve groove 130 is provided on the concave tube wall arranged at the lower end of the round tube 110. The round tube 110 is arranged as a concave tube wall, which is convenient for clamping and fixing, and is suitable for assembling the oil dipstick sleeve 160 in different scenes and at different angles. The sleeve groove 130 is adapted to the outer surface of the oil dipstick sleeve 160. A magnet block 140 is embedded and fixed on the inner wall of the sleeve groove 130 near the bottom end. The oil dipstick sleeve 160 is sucked by the magnet block 140, which facilitates the striking assembly and fixing position of the oil dipstick sleeve 160 and avoids the oil dipstick sleeve 160 from being removed from the sleeve during the striking process. The tube 110 is a non-magnetic copper alloy tube to ensure that the magnetic force of the magnet block 140 is not disturbed and to extend its service life. The bottom end of the round tube 110 is provided with a sleeve step surface 150, which is sleeved on a step 161 provided at the lower end of the oil dipstick sleeve 160. The sleeve groove 130 is a semicircular groove, and the sleeve groove 130 extends to the bottom through the sleeve step surface 150. The sleeve step surface 150 coincides with the step 161, so that the step 161 can be evenly stressed during the knocking process, effectively protecting the step 161. At the same time, the oil dipstick sleeve 160 is effectively positioned to avoid the oil dipstick sleeve 160 from being deviated and damaging the cylinder body during the knocking process. The round tube 110, the knocking surface 120 and the sleeve step surface 150 are an integrated structure, which is easy to manufacture, has good structural rigidity and is resistant to knocking.

[0034] See also Figure 4 , 5In one embodiment of the present invention, it also includes a clamping mechanism 20, which includes a fixed block 210, a movable block 220 and a clamping piece 240. The movable blocks 220 are symmetrically arranged in two pieces, one end of the two movable blocks 220 is hinged to the fixed block 210, the two movable blocks 220 are hinged to the fixed block 210 through a pin shaft, and the other ends of the two movable blocks 220 are fixed to the fixed block 210 through a locking bolt 230. The fixed block 210 and the movable block 220 are provided with a semicircular groove on the opposite side, and the clamping piece 240 is screwed to the two movable blocks 220. The fixed block 210 and the clamping piece 240 are both engaged with the outer wall of the circular tube 110 below the striking surface 120. Specifically, the clamping piece 240 includes a screw 241 and an arc-shaped clamping plate 242. The screw 241 passes through the middle part of the movable block 220 and is screwed. The arc-shaped clamping plate 242 is rotated to connect The end connected to the screw 241 extends to the inner side of the movable block 220, and the arc-shaped clamping plate 242 is abutted against the outer wall of the circular tube 110 on the side away from the screw 241. The contact surface between the arc-shaped clamping plate 242 and the outer wall of the circular tube 110 is bonded with an anti-skid pad 243 to increase the friction between the arc-shaped clamping plate 242 and the outer wall of the circular tube 110. The end of the screw 241 away from the arc-shaped clamping plate 242 is fixedly sleeved with a rocking wheel 244. The movable block 220 is rotated around the fixed block 210, so that the fixed block 210 and the movable block 220 are engaged with the outer peripheral wall of the circular tube 110 below the striking surface 120, and are locked and fixed by the locking bolt 230. The screw 241 is rotated by the rocking wheel 244 to drive the arc-shaped clamping plate 242 to abut against the outer peripheral wall of the circular tube 110, so that the circular tube 110 is engaged and fixed, and at the same time, the clamping mechanism 20 can be adapted to the use of circular tubes 110 of different diameters.

[0035] In the specific setting, two groups of shock-absorbing springs 260 are symmetrically fixed on the outer wall of the fixed block 210 away from the movable block 220 through the connecting rod 250. The ends of the two groups of shock-absorbing springs 260 away from the fixed block 210 are fixed with shock-proof handles 270 through the connecting rod 250. In the process of the vibration generated by knocking the round tube 110 being transmitted to the shock-proof handle 270 through the fixed block 210, the rebound force of the two groups of shock-absorbing springs 260 can offset and disperse the vibration force, so that the vibration transmitted to the worker's arm will be relatively small, avoiding the danger caused by the vibration. The shock absorbing spring 260 is provided with a protective sleeve 261 on the outside, and the two ends of the protective sleeve 261 are respectively fixed to the connecting rods 250 on the two ends of the shock absorbing spring 260 to protect the shock absorbing spring 260. The outer peripheral side of the shockproof handle 270 is provided with a shock-absorbing rubber sleeve 271. The shock-absorbing rubber sleeve 271 is used to further reduce shock when the shockproof handle 270 is held. The shock-absorbing rubber sleeve 271 is provided with an anti-skid mesh structure 272. The anti-skid mesh structure 272 increases the friction force to ensure that the use process is reliable and not smooth.

[0036] Specifically, the working principle of the tooling for installing the oil dipstick sleeve is as follows: when in use, the movable block 220 is rotated around the fixed block 210, so that the fixed block 210 and the movable block 220 are engaged with the outer peripheral wall of the circular tube 110 below the knocking surface 120, and are locked and fixed by the locking bolt 230, and the screw rod 241 is rotated by the rocking wheel 244 to drive the arc-shaped clamping plate 242 to press against the outer peripheral wall of the circular tube 110, so as to clamp and fix the circular tube 110, which is convenient for the operator to hold and fix, and is suitable for assembling the oil dipstick sleeve 160 in different scenes and at different angles, and the sleeve step surface 150 is abutted against the step 161 of the oil dipstick sleeve 160, and the part of the oil dipstick sleeve 160 that does not need to be driven into the cylinder body is stored in the sleeve groove 130, and the oil dipstick sleeve 160 is sucked by the magnet block 140, so as to facilitate the knocking assembly and fixing position of the oil dipstick sleeve 160, and avoid the oil dipstick from being knocked during the knocking process. The dipstick sleeve 160 falls off from the sleeve groove 130, which facilitates the operator's operation, reduces the labor intensity of the assemblers, and greatly improves the production efficiency and assembly quality. Then, the operator holds the anti-vibration handle 270 with one hand, aligns it with the process hole where the sleeve needs to be driven in, and uses a hammer to hit the striking surface 120 with the other hand, so that the oil dipstick sleeve 160 is knocked into the process hole to complete the assembly of the engine oil dipstick sleeve. The top surface of the striking surface 120 is set as a square plane, which increases the striking area, facilitates accurate striking on the striking surface 120, effectively improves the striking accuracy, and improves the production efficiency. The two sets of shock-absorbing springs 260 and the shock-absorbing rubber sleeve 271 can offset and disperse the vibration generated by striking the circular tube 110, so that the vibration transmitted to the worker's arm will be relatively small, avoiding the harm caused by vibration, and making the worker more comfortable when working.
