Description

Technical Field

[0001] This invention relates to a cylinder block oblique oil passage deburring device, which relates to the field of engine manufacturing technology, and in particular to deburring the oblique oil passage and camshaft intersection hole without removing the main bearing cap. Background Technology

[0002] Burrs in the oil passages of automotive engine cylinder blocks can fall onto the lubricated parts due to the impact of internal oil circulation, causing wear on the lubricated components and directly affecting the engine's lifespan. Therefore, in the actual cylinder block production process, burrs in the cylinder block oil passage holes need to be carefully cleaned. The current production process is: automatic removal of the main bearing cap - deburring of the oil passage intersection holes - automatic assembly of the main bearing cap. This requires the introduction of two automated machines to complete the deburring of the oil passage intersection holes. This increases the cost of introducing and operating the equipment, as well as the floor space required for the production line.

[0003] In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a new type of cylinder block inclined oil passage deflashing device to overcome the problems existing in the prior art. Summary of the Invention

[0004] The existing technology for deburring the main bearing cover requires two machines, resulting in high costs and large footprint. This invention addresses the problem of deburring the cylinder block's inclined oil passage by providing a deburring device. The invention utilizes a guide tube feeding mechanism, a flexible shaft tool feeding mechanism, a linked rotary transmission mechanism, and electrical position control to feed the tool into the intersection point in a non-linear state for reciprocating deburring. This achieves deburring without removing the bearing cover, improving workpiece quality and reducing costs and equipment footprint.

[0005] The technical means employed in this invention are as follows:

[0006] A cylinder block inclined oil passage deflashing device includes: a guide tube, a guide tube fixing device, a flexible shaft cutter, a lifting plate, an assembly plate, a guide tube feeding mechanism, a flexible shaft cutter feeding mechanism, and a linkage rotation mechanism.

[0007] Furthermore, the flexible shaft tool feed mechanism and the guide tube feeding mechanism are fixedly mounted at the front and rear ends of the assembly plate;

[0008] Furthermore, the front end of the catheter insertion mechanism is equipped with a catheter via a lifting plate and a catheter fixing device;

[0009] Furthermore, the front end of the flexible shaft tool feed mechanism is equipped with a linkage rotation mechanism;

[0010] Furthermore, the output end of the linkage rotation mechanism is connected to the flexible shaft cutter assembled inside the guide tube.

[0011] Furthermore, the conduit feeding mechanism includes: cylinder B, guide rail B, cylinder B connecting plate, and connector;

[0012] Furthermore, cylinder B is fixedly mounted on cylinder B connecting plate;

[0013] Furthermore, the cylinder B connecting plate is connected to the fixed base by bolts;

[0014] Furthermore, the front end of the cylinder rod of cylinder B is connected to the connector;

[0015] Furthermore, a guide rail B is provided between the bottom end of the connector and the connecting plate of cylinder B to guide and support the movement direction of the connector and ensure the stability of the movement process.

[0016] Furthermore, a lifting plate is installed at the top of the connector.

[0017] Furthermore, there are multiple catheter fixing devices, each of which has an elongated hole and is fixedly mounted on the top surface of the lifting plate;

[0018] Furthermore, each catheter fixing device has a catheter installed in its elongated hole, and the catheter can move and change angle within the elongated hole.

[0019] Furthermore, the flexible shaft tool feed mechanism includes: a linkage rotary mechanism connecting plate, cylinder A, guide rail A, and cylinder A connecting plate;

[0020] Furthermore, cylinder A is fixedly mounted on cylinder A connecting plate;

[0021] Furthermore, the cylinder A connecting plate is fixedly connected to the front end face of the assembly plate by bolts;

[0022] Furthermore, the front end of the cylinder rod of cylinder A is connected to the bottom end of the connecting plate of the linkage rotation mechanism;

[0023] Furthermore, a guide rail A is provided between the bottom end of the connecting plate of the linkage rotary mechanism and the connecting plate of cylinder A to guide and support the movement direction of the connecting plate of the linkage rotary mechanism and ensure the stability of the movement process.

[0024] Furthermore, the top of the connecting plate of the linkage rotation mechanism is equipped with a linkage rotation mechanism.

[0025] Furthermore, the linkage rotation mechanism includes: a coupling, a synchronous pulley, a synchronous belt, a bearing housing, a bearing, a shaft, and a pneumatic motor;

[0026] Furthermore, the shaft is mounted on the connecting plate of the linkage rotation mechanism via bearings and bearing housings;

[0027] Furthermore, the top end of the shaft is connected to the bottom end of a flexible shaft cutter housed inside the guide tube via a coupling;

[0028] Furthermore, a synchronous pulley is mounted on each of the upper and lower ends of the shaft located on the bearing housing, and a synchronous belt is mounted between the synchronous pulleys at the upper and lower ends of two adjacent shafts.

[0029] Furthermore, the pneumatic motor is fixedly mounted on one end of the connecting plate of the linkage rotation mechanism, and its output end is equipped with a synchronous pulley. It is connected to the synchronous pulley on the shaft at one end through the synchronous belt, thereby driving the connected shaft to rotate in sequence. The shaft drives the flexible shaft cutter to rotate through the coupling 3.

[0030] The working process of this invention is as follows: Cylinder B pushes the lifting plate, guide tube, guide tube fixing device, and flexible shaft cutter feeding mechanism to move obliquely upward through guide rail B, moving the guide tube to the side of the oblique oil passage in the cylinder body; then cylinder A pushes the linkage rotary transmission mechanism to move obliquely upward through guide rail A, and the flexible shaft cutter is inserted into the intersection of the main oil passage and the camshaft hole through the guide tube. The pneumatic motor rotates, driving each flexible shaft to rotate and remove the burrs at the intersection of the main oil passage and the camshaft hole. After deburring is completed, the mechanical action process is reversed, and the device returns to its original position.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] 1. The cylinder block inclined oil passage deburring device provided by the present invention is equipped with a linkage rotation mechanism, which realizes that a single pneumatic motor drives all flexible shaft cutters to rotate synchronously to remove burrs, saving power source and simplifying structure.

[0033] 2. The cylinder block inclined oil passage deflashing device provided by the present invention allows the flexible shaft cutter to achieve its own rotation while moving in a non-linear manner through the guidance of the guide tube, enabling it to reach complex spaces for operation.

[0034] 3. The cylinder inclined oil passage deflashing device provided by the present invention has a two-stage cylinder lifting mechanism, which provides space avoidance for the cylinder of the roller conveyor station, realizes the approach of the guide tube in one step, and realizes the extension of the flexible shaft cutter to reach the intersection of the main oil passage and the camshaft hole.

[0035] In summary, the technical solution of this invention solves the problem of deburring operations in complex spaces that are inaccessible in the prior art; the use of a single power source linkage reduces energy consumption and saves equipment space; furthermore, it reduces the need for equipment to be introduced for the two processes of disassembling and assembling the main bearing cover in the production line, greatly saving equipment introduction costs.
