Abstract
The utility model discloses a valve seat removing device, which comprises a supporting assembly supported on an air cylinder cover. A crow bar is supported by the supporting assembly. The front end of the crow bar is connected with a connecting body. The lower end of the connecting body is provided with a jaw. A valve seat is clamped by the jaw. The valve seat is removed by prying the crow bar. The valve seat removing device avoids damage to a bottom hole of the valve seat in the process of removing the valve seat from the air cylinder cover.
Description
Technical field
The utility model relates to a kind of device that valve seat insert takes out from cylinder head that is used for.
Background technology
The cylinder head sub-unit of old engine through disassembling, after dividing detection limit, find that the valve seat insert sealing surface has been subjected to heavy wear and corrosion, if without replacing, can't assemble engine, and in the prior art, in that valve seat insert is caused damage to the valve seat bottom outlet easily from the process that cylinder head is taken out, influenced the manufacturing again of cylinder head sub-unit.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can take out old valve seat insert fast, avoids the valve seat bottom outlet is caused the valve seat insert withdrawing device of damage simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: the valve seat insert withdrawing device, comprise the support assembly that is supported on the cylinder head, and described support assembly is supported with crowbar, the front end of described crowbar is connected with connector, and claw is installed in described connector lower end.
As optimized technical scheme, described claw is two.
As optimized technical scheme, be provided with the claw distance adjusting system between the described claw.
As optimized technical scheme, described claw distance adjusting system comprises the bolt that is installed on one of them claw, and the end of described bolt is resisted against on the corresponding claw.
Owing to adopted technique scheme, the valve seat insert withdrawing device comprises the support assembly that is supported on the cylinder head, and described support assembly is supported with crowbar, and the front end of described crowbar is connected with connector, and claw is installed in described connector lower end; Block valve seat insert by claw, prize crowbar valve seat insert is taken out, the damage of having avoided valve seat insert from the process that cylinder head is taken out the valve seat bottom outlet to be caused has realized the quick taking-up of valve seat insert simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of valve seat insert withdrawing device among the utility model embodiment.
The specific embodiment
As depicted in figs. 1 and 2, the valve seat insert withdrawing device, comprise the support assembly 1 that is supported on the cylinder head, described support assembly 1 is supported with crowbar 2, the front end of described crowbar 2 is connected with connector 3, claw is installed in described connector 3 lower ends, and described claw is two, comprising: first claw 4 and second claw 6; Design has claw distance adjusting system, described claw distance adjusting system to comprise the bolt 5 that is installed on described first claw 4 between described first claw 4 and second claw 6, and the end of described bolt 5 is resisted against on corresponding described second claw 6.
During use, elder generation with two half slots of valve seat endoporus symmetrical milling, after the distance between the adjustment claw, puts into groove with claw with half garden arc milling cutter, adjusts support assembly and makes claw vertical with the valve seat endoporus, valve seat can be taken out to pressing down crowbar then.
Block valve seat insert by claw, prize crowbar valve seat insert is taken out, the damage of having avoided valve seat insert from the process that cylinder head is taken out the valve seat bottom outlet to be caused has realized the quick taking-up of valve seat insert.
