Description

Technical Field

[0001] The present application relates to the technical field of vehicle production, and in particular to a deburring machine for an engine rocker shaft. Background Art

[0002] As one of the components of the engine, the rocker arm usually needs to be fixed to the rocker arm bracket using a rocker arm shaft, and the rocker arm bracket is fixed to the cylinder of the engine. The rocker arm shaft is usually a straight rod, and a through hole is provided in the middle of the rocker arm shaft along the axial direction, and a plurality of through holes are provided on the side wall of the rocker arm shaft. When working, a certain amount of lubricating fluid is stored in the inner cavity of the rocker arm shaft, and the lubricating fluid passes through the through hole to lubricate the gap between the rocker arm shaft and the rocker arm.

[0003] In the related art, during the production of the rocker shaft, it is usually necessary to grind the inner wall of the rocker shaft to remove the burrs on the inner wall of the rocker shaft. The operator first places the rocker shaft on a deburring device, then drives a cutter to perform forward cutting and deburring on the rocker shaft, then removes the rocker shaft, places it on another deburring device, performs reverse deburring on the rocker shaft, and completes the burr removal operation.

[0004] With regard to the above-mentioned related technologies, the operator needs to remove and install the rocker shaft several times before completing the deburring operation on the inner wall of the rocker shaft, thereby affecting the operator's work efficiency and increasing safety hazards to a certain extent. Utility Model Content

[0005] In order to be able to control the forward rotation or flipping of the cutting tool at one time, thereby completing the deburring operation on the rocker arm shaft, the present application provides an engine rocker arm shaft deburring machine.

[0006] The present application provides an engine rocker shaft deburring machine, which adopts the following technical solution:

[0007] An engine rocker shaft deburring machine comprises a workbench and a cutting device, wherein the cutting device comprises a connecting plate and a limiting block, wherein the connecting plate is mounted on the workbench and can slide in a vertical direction, wherein the connecting plate is fixedly connected to a plurality of limiting plates; and the limiting block is fixedly connected to the workbench;

[0008] The cutting device also includes a track, a driving part, a first motor and a cutting knife. The track is fixedly connected to the workbench, the driving part slides along the track, and the first motor is fixed to the driving part and is used to drive the cutting knife to rotate.

[0009] By adopting the above technical solution, the workbench provides support for the installation of the entire device, and the cutting device can be used as a cleaning structure for the burrs on the rocker shaft. When cleaning the burrs on the rocker shaft, the operator drives the connecting plate to move downward. At this time, the rocker shaft abuts against the side walls of the limit plate and the limit block to limit the rocker shaft. Then the driving part slides along the track, thereby driving the first motor and the cutting knife to slide. The first motor drives the cutting knife to rotate by forward and reverse rotation to clean the burrs on the rocker shaft. Then the limit plate moves upward, so that the rocker shaft can leave the limit block and continue to slide along the feeding direction. The first motor drives the cutting knife to rotate forward and reverse, thereby avoiding the operator from repeatedly installing the rocker shaft, improving the operator's work efficiency, and facilitating subsequent related operations on the rocker shaft.

[0010] Optionally, a limiting groove is provided on the top wall of the limiting block, and the limiting groove is used to accommodate the rocker arm shaft;

[0011] The cutting device further comprises a limiting block, which is located above the limiting groove and slides in a vertical direction.

[0012] By adopting the above technical solution, the top wall of the fixed block is provided with a limit groove, and the setting of the limit groove can improve the stability of the rocker shaft during the deburring operation of the rocker shaft. At the same time, the limit block slides in the vertical direction, so that the limit block can abut against the side wall of the rocker shaft, further improving the limiting effect of the rocker shaft, ensuring the stability of the workpiece, and at the same time improving the deburring effect of the cutting tool on the rocker shaft.

[0013] Optionally, it further comprises a feeding device, wherein the feeding device comprises a supporting plate, and the supporting plate is fixedly connected to the workbench;

[0014] The support plate is fixedly connected to limit rods on both sides along the length direction, and the two ends of the rocker shaft are respectively located in the inner cavity of the limit rods;

[0015] A blocking plate is provided at the end of the limiting rod, and the blocking plate moves in a vertical direction.

[0016] By adopting the above technical solution, the support plate provides support for the installation of the limit rod. The setting of the limit rod makes it convenient for the operator to store and limit the rocker shaft. The blocking plate slides in the vertical direction, so that the rocker shaft can enter the limit groove of the fixed block in turn, and the rocker shaft can be deburred, avoiding the operator from holding the rocker shaft and performing the rocker shaft unloading operation.

[0017] Optionally, the support plate is arranged at an angle.

[0018] By adopting the above technical solution, the support plate is tilted, and then the limit plate is tilted. At this time, the rocker shaft will slide downward under the action of gravity. At the same time, the setting of the blocking plate makes it easy to control the rocker shaft to enter the limit groove of the limit block in turn, and clean the burrs on the rocker shaft.

[0019] Optionally, a guide rod is provided between the two limit rods, the guide rod is parallel to the limit rod, and the guide rod is fixedly connected to the support plate.

[0020] By adopting the above technical solution, the setting of the guide rod can reduce the friction between the guide rod and the limit rod to a certain extent, thereby enabling the rocker arm shaft to slide on the support plate faster, thereby improving the preparation speed of the rocker arm shaft.

[0021] Optionally, the feeding device further comprises a pressing plate, wherein the pressing plate and the blocking plate are arranged in sequence along the vertical direction, and the pressing plate moves along the vertical direction.

[0022] By adopting the above technical solution, when the blocking plate blocks and limits the rocker arm shaft so that it cannot enter the limit block, the clamping plate moves downward at the same time, and fixes the rocker arm shaft at the limit rod, which can further provide limitation for the rocker arm shaft and prevent the rocker arm shaft from entering the limit groove and affecting the rocker arm shaft that is undergoing deburring operation.

[0023] Optionally, the feeding device also includes a partition plate and a material stripping plate, wherein the partition plate and the material stripping plate are located between the direction of the connection line between the clamping plate and the blocking plate, and the connection direction between the partition plate and the material stripping plate is perpendicular to the feeding direction, and the partition plate and the material stripping plate both move in the vertical direction.

[0024] By adopting the above technical solution, the partition plate can cooperate with the clamping plate to clamp the rocker shaft being prepared. When the next rocker shaft needs to enter the limit groove, the partition plate clamps the next rocker shaft, and at the same time, the material removal plate moves downward to remove the material from the rocker shaft, thereby allowing the rocker shaft to enter the limit block.

[0025] Optionally, the bottom of the partition plate is wedge-shaped.

[0026] By adopting the above technical solution, the bottom of the partition plate is wedge-shaped, which enables the partition plate to reach between two adjacent rocker shafts instead of staying on the surface of the rocker shaft, thereby better providing positioning for the rocker shaft.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By setting the cutting device, the rocker shaft can be deburred in the positive direction and the reverse direction without shifting the rocker shaft, thereby improving the working efficiency of the rocker shaft.

[0029] 2. By setting up a feeding device, the rocker arm shaft can be sent to the limit groove in sequence, and the rocker arm shaft can be deburred;

[0030] 3. By setting up a supporting device, it is possible to provide installation support for multiple cylinders, thereby facilitating corresponding deburring operations on the rocker arm shaft. BRIEF DESCRIPTION OF THE DRAWINGS
