Description

Technical Field

[0001] The present invention belongs to the technical field of engine processing equipment, and particularly relates to a general-purpose pneumatic pressing tooling for engine valve retainers. Background Art

[0002] During the engine assembly process, there are various types of engine cylinder heads with different sizes. Even the commonly used valve retainers are divided into two types: clamped valve retainers and non-clamped valve retainers. This makes it very difficult to unify the tooling for pressing valve retainers. When encountering small-batch engine assembly, it is necessary to frequently replace different-sized and different-model pressing tooling for valve retainers, which greatly affects production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a general-purpose pressing tooling for valve retainers with a simple structure, convenient operation, and capable of meeting small-batch production of engines.

[0004] The purpose of the present invention is achieved as follows: A general-purpose pneumatic pressing tooling for engine valve retainers includes a frame platform and rollers. The rollers are arranged at the bottom of the frame platform. A bracket is fixedly connected to the frame platform. A support block is fixedly connected to the upper part of the bracket. A slide base is arranged above the support block. The rear side of the slide base is fixed to the bracket. A linear slide rail is fixed to the front side of the slide base. A first slider is slidably connected to the linear slide rail. An optical axis slide rail is fixed to the upper part of the slide base. A second slider is slidably connected to the optical axis slide rail. An L-shaped bracket is fixed above the second slider. A spring balancer is suspended below the L-shaped bracket. The spring balancer is connected to a T-shaped slide plate through a steel wire rope at the lower end. The T-shaped slide plate is slidably connected to a vertical slide rail through a slider. The vertical slide rail is fixed to the upper part of a fixed back plate. The fixed back plate is fixed to the first slider. Pneumatic brakes are fixed on both sides of the fixed back plate. A pressing cylinder is fixedly connected to the T-shaped slide plate. A valve retainer pressing head is fixedly connected to the lower end of the pressing cylinder. A handle is fixedly connected to the upper part of the pressing cylinder. A fixed base is fixedly connected to the frame platform. A flipping support frame is fixed on the fixed base. A cylinder head support plate is fixedly connected to the upper part of the flipping support frame. A first fixing frame and a second fixing frame are respectively arranged at the front and rear of the cylinder head support plate.

[0005] The frame platform is composed of two platforms, an upper platform and a lower platform. The top of the bracket is fixedly connected through a connecting pipe. A fixing frame is fixedly connected at the connection between the frame platform and the bracket.

[0006] The slide base is made of square tubes, and a plurality of hollow round holes are evenly arranged on the square tubes.

[0007] The described optical axis slide rail is fixed on the slide base through a support base. A square plate is fixedly connected between the second slider and the L-shaped bracket, and a solenoid valve of a downward pressing air cylinder is arranged on the back of the L-shaped bracket.

[0008] The described pneumatic brake relies on air pressure to push the friction plates on both sides inside to fix and clamp the T-shaped slide plate, and the gap of the pneumatic brake corresponds to the two wings of the T-shaped slide plate.

[0009] The described handle is fixed on the upper part of the downward pressing air cylinder through a connecting piece, and a start button is arranged on the handle to control the solenoid valve of the downward pressing air cylinder.

[0010] A polyurethane rubber pad is fixed on the upper surface of the cylinder head support plate. The described flipping support frame is composed of a support plate, a rotating rod and a support frame. The support plate is fixed on the fixed base and is rotatably connected to the rotating rod, and the support frame is fixedly connected to the rotating rod.

[0011] An angle adjusting block is arranged in the middle of the described fixed base. The angle adjusting block is composed of a serrated rack and two supporting blocks with inclined surfaces. There are serrated grooves corresponding to the rack at the bottom of the supporting blocks, and the rack is fixed on the fixed base.

[0012] Working steps:

[0013] Step 1: Place the engine cylinder head with the valve stem inserted on the cylinder head support plate;

[0014] Step 2: Adjust the first fixing frame and the second fixing frame so that the first fixing frame and the second fixing frame cooperate to fix the cylinder head well;

[0015] Step 3: Adjust the angle adjusting block according to the cylinder head model;

[0016] Step 4: Flip the cylinder head to one side so that the lock piece press head, the valve lock armor and the valve stem are all on a vertical straight line;

[0017] Step 5: Place the valve spring and the valve spring seat at the position of the valve stem head of the cylinder head;

[0018] Step 6: Put the valve lock piece into the lock piece press head and clamp it;

[0019] Step 7: Hold the lock piece press head with the left hand and press down with the right hand holding the control handle;

[0020] Step 8: Press the start button on the handle when the lock piece press head touches the valve lock armor;

[0021] Step 9: Start the pneumatic brakes on both sides and clamp the T-shaped slide plate. At the same time, the downward pressing air cylinder presses down and the lock piece pressing is completed;

[0022] Step 10: Release the start button, and the spring balancer automatically pulls the downward pressing air cylinder back to the original position, and the single-time lock piece pressing ends.

[0023] Advantages of the present invention: By manually controlling the solenoid valve, the cylinder is pressed down to drive the lock piece press head to complete the action of pressing the engine valve lock piece; the lock piece press head can be freely replaced according to the type of lock piece, and the flipping angle of the support bottom plate can be quickly adjusted according to the specific cylinder head model. It not only has a wide range of applications, but also can quickly complete the corresponding conversion of different types of lock pieces, and can effectively meet the production of small batches of engines; the hollow round holes and square holes on the square tube can effectively reduce the weight of the equipment. The linear slide rail and the optical axis slide rail are used in combination to ensure that the lock piece pressing structure can move left and right in a horizontal position to ensure the pressing accuracy. The flipping support frame can make the cylinder block flip to the other side to continue pressing the lock piece when one side of the lock piece is pressed, further improving the pressing efficiency of the lock piece; generally speaking, the present invention is reasonably designed and has the advantages of simple structure, convenient operation, high production efficiency, and can meet the small batch production of engines.
