Description

Technical Field

[0001] The utility model belongs to the technical field of engine maintenance, and particularly relates to an engine gear fixator. Background Art

[0002] As a machine that converts other forms of energy into mechanical energy, engines are widely used in various power devices, such as internal combustion engines (such as gasoline engines, diesel engines), external combustion engines (such as steam engines), jet engines, and electric motors. In the structure of an engine, gears are indispensable transmission components. When repairing and replacing the belt on an engine gear, it is necessary to fix the engine gear.

[0003] Currently, the Chinese utility model patent announced as CN213381314U discloses a timing fixator for a double camshaft of an automobile engine. By setting a double-ear bottom plate and two symmetrically arranged tooth pullers slidably connected to the double-ear bottom plate, through the above settings, the double camshafts can be fixed simultaneously after the timing is completed, and at the same time, the stability of the fixation of the double camshafts can be ensured to prevent their positions from changing.

[0004] When using this patent, it is necessary to loosen the tightening bolt and the locking bolt, horizontally buckle the double-ear bottom plate on the gears of the double camshaft, and then through a series of operations such as a rotating rod, a sliding piece, and a pull rod, tighten the two engine gears to avoid the change of the positions of the engine gears. However, this operation is cumbersome and increases the maintenance time. Content of the Utility Model

[0005] The purpose of the utility model is to provide an engine gear fixator, which solves the problem that the existing timing fixator for a double camshaft of an automobile engine has cumbersome operation and increases the maintenance time.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions. An engine gear fixator includes engine gears, the number of the engine gears is two, and a fixing mechanism is arranged between the two engine gears;

[0007] The fixing mechanism includes a fixing frame, a moving block, teeth, a transmission component, and a limiting component. The fixing frame is arranged between the two engine gears. The moving block is slidably connected to the inside of the fixing frame. The number of the moving blocks is two and they are symmetrically arranged. The teeth are welded to the moving block. The number of the teeth is several and they are evenly distributed on the side wall of the moving block. The transmission component is arranged on the moving block. The limiting components are opened at the upper and lower ends inside the fixing frame, and the limiting components are used to limit the sliding of the moving block.

[0008] With the above technical solution, by setting the engine gears and the fixing mechanism, when it is necessary to repair and replace the belt on the engine gears, it is only necessary to snap the fixing mechanism between the two engine gears to prevent the engine gears from rotating and changing their positions. The operation is simple and the repair time is saved. The fixing mechanism includes a fixing frame, a moving block, teeth, a transmission component and a limiting component. When in use, according to the distance between the two engine gears, the transmission component drives the moving block to move in the fixing frame. At this time, the limiting component can limit the movement of the moving block. After the moving block moves to the appropriate position, the teeth on the moving block are engaged with the engine gears to clamp the two engine gears tightly, preventing the engine gears from rotating and changing their positions, and the operation is convenient.

[0009] Further: The transmission component includes a connecting rod, a rotating rod and a rotating handle. The connecting rod is fixedly connected to one end of the moving block away from the teeth. One end of the rotating rod is rotatably connected to the side wall of the fixing frame, and the other end of the rotating rod extends to the outside of the fixing frame. The rotating handle is fixedly connected to the other end of the rotating rod, and the connecting surface of the rotating rod and the connecting rod is meshed and connected.

[0010] With the above technical solution, by setting the connecting rod, the rotating rod and the rotating handle, when it is necessary to change the position of the moving block, it is only necessary to drive the rotating rod to rotate through the rotating handle. Since the rotating rod is meshed and connected with the connecting rod, it can drive the connecting rod to move on the surface of the rotating rod, and then drive the moving block to move, enabling the moving block to adapt to engine gears with different distances.

[0011] Further: The limiting component includes limiting grooves and limiting blocks. The limiting grooves are opened at the upper and lower ends inside the fixing frame. The number of the limiting grooves is four and they are symmetrically arranged. The limiting blocks are fixedly connected to the upper and lower ends of the moving block, and the limiting blocks are slidably connected in the limiting grooves.

[0012] With the above technical solution, by setting the limiting grooves and the limiting blocks, during the movement of the moving block, the limiting blocks can move in the limiting grooves. Through the cooperation of the limiting blocks and the limiting grooves, the movement of the moving block can be limited, enabling the moving block to move stably in the fixing frame.

[0013] Further: Anti-slip grooves are formed on the rotating handle. The number of the anti-slip grooves is several and they are arranged circumferentially.

[0014] With the above technical solution, by setting the anti-slip grooves, during use, the anti-slip grooves can increase the friction between the user and the rotating handle, enabling the user to better turn the rotating handle and drive the moving block to move in the fixing frame better.

[0015] Furthermore: a holding handle is provided on the surface of the fixing frame, and the cross section of the holding handle is U-shaped.

[0016] By adopting the above technical solution, a holding handle is provided. When in use, the holding handle can provide a fulcrum for the user, making it easy to place the two moving blocks between the two engine gears, making it easy for the teeth on the moving blocks to mesh with the engine gears, and making it easy to fix the engine gears.

[0017] Furthermore: the contact surfaces of the limit block and the limit groove are both smoothly arranged.

[0018] By adopting the above technical solution, the contact surface of the limit block and the limit groove is set to be smooth, which can reduce the friction between the limit block and the limit groove, enable the limit block to move better in the limit groove, and thus facilitate the movement of the moving block in the fixed frame.

[0019] Furthermore: the teeth on the moving block are meshed and connected with the engine gear.

[0020] By adopting the above technical solution, the connection mode between the teeth and the engine gear is set so that the teeth and the engine gear are meshed and connected, and the engine gear can be fixed by the teeth to avoid changes in the position of the engine gear.

[0021] Furthermore: the surface of the holding handle is sprayed with an anti-slip coating for increasing friction.

[0022] By adopting the above technical solution and providing an anti-slip coating, the anti-slip coating on the holding handle can increase the friction between the user and the holding handle during use, so that the staff can better hold the holding handle.

[0023] In summary, the utility model has the following beneficial effects:

[0024] By setting up a fixing mechanism, when in use, according to the spacing between the two engine gears, the moving block is driven to move in the fixed frame through the transmission component. At this time, the limiting component can limit the movement of the moving block. After the moving block moves to a suitable position, the teeth on the moving block mesh with the engine gears to clamp the two engine gears, thereby preventing the engine gears from rotating and changing their positions, and the operation is convenient.

[0025] By setting the connecting rod, the rotating rod and the rotating handle, when the position of the moving block needs to be changed, it is only necessary to drive the rotating rod to rotate by turning the handle. Since the rotating rod is meshed with the connecting rod, the connecting rod can be driven to move on the surface of the rotating rod, and then the moving block can be driven to move, so that the moving block can adapt to engine gears with different spacings.

[0026] Based on the above improvement points, the overall technical effect achieved by this device is that the fixed frame can be directly placed between two engine gears, enabling the teeth to mesh with the engine gears, fixing the engine gears, with convenient operation and reduced maintenance time.

The limiting component 205 is opened at the upper and lower ends inside the fixing frame 201, and the limiting component 205 is used to limit the sliding of the moving blocks 202.

[0037] By setting the engine gear 1 and the fixing mechanism 2, when it is necessary to repair and replace the belt on the engine gear 1, it is only necessary to snap the fixing mechanism 2 between the two engine gears 1 to prevent the engine gear 1 from rotating and its position from changing. The operation is simple and the repair time is saved. The fixing mechanism 2 includes a fixing frame 201, a moving block 202, teeth 203, a transmission assembly 204, and a limiting assembly 205. When in use, according to the distance between the two engine gears 1, the transmission assembly 204 drives the moving block 202 to move in the fixing frame 201. At this time, the limiting assembly 205 can limit the movement of the moving block 202. After the moving block 202 moves to a suitable position, the teeth 203 on the moving block 202 are engaged with the engine gear 1, so that the two engine gears 1 can be clamped tightly to prevent the engine gear 1 from rotating and its position from changing, and the operation is convenient.

The limiting blocks 2052 are fixedly connected to the upper and lower ends of the moving block 202. The limiting blocks 2052 are slidably connected in the limiting grooves 2051. By setting the limiting grooves 2051 and the limiting blocks 2052, during the movement of the moving block 202, the limiting blocks 2052 can move in the limiting grooves 2051.

[0045] Brief description of the usage process:

[0046] When in use, firstly, according to the spacing between the two engine gears 1, the handle 2043 is turned to drive the rotating rod 2042 to rotate. Since the rotating rod 2042 is meshed and connected with the connecting rod 2041, the connecting rod 2041 can be driven to move on the surface of the rotating rod 2042, and then the moving block 202 can be driven to move, so that the moving block 202 can adapt to the engine gears 1 with different spacings.
