Description

Technical Field

[0001] The invention relates to the technical field of diesel filter surface treatment, in particular to a processing device used for diesel filter surface treatment. Background Art

[0002] Diesel filters are used to remove particulate matter, moisture and other contaminants from diesel to protect the engine. Clean diesel can reduce engine wear and extend its service life. Grinding and polishing the inside of the filter housing can remove burrs, oxide layers and unevenness, improving the performance and corrosion resistance of the filter. The smooth surface helps ensure the seal between the filter and the engine to prevent leakage.

[0003] However, the prior art tends to neglect the grinding and polishing of the bottom and side walls inside the diesel filter housing, resulting in incomplete grinding of the connection between the bottom and side walls inside the filter housing. Therefore, a processing equipment for surface treatment of diesel filters is urgently needed. Summary of the invention

[0004] In view of the above technical problems, the technical solution adopted by the present invention is: a processing equipment for the surface treatment of a diesel filter, including a supporting mechanism and a polishing mechanism. The supporting mechanism includes a support plate column and an active column. The convex column of the active column is axially slidably installed on the axial rail of the support plate column, and the convex column and the annular groove of the support plate column are slidably matched. The hollow column of the active column is axially slidably installed with a driven column, and multiple groups of adjustment mechanisms are evenly connected between the hollow column and the driven column. The connecting rod of the adjustment mechanism is rotatably connected to the adjustment component, the main polisher of the polishing mechanism is rotatably connected to the polishing component, the main polisher is rotatably installed at the rotating connection between the connecting rod and the adjusting component, the tail of the polishing component is slidably installed on the connecting rod, and the limit assembly on the connecting rod adjusts the angle between the main polisher and the polishing component. A cam column is rotatably installed between the support plate column and the active column, and the convex column of the active column is slidably installed on the arc track of the cam column. The power mechanism on the support plate column drives the cam column to drive the convex column to slide from the axial rail to the annular groove, and the polishing mechanism polishes the inside of the filter housing.

[0005] Furthermore, the support mechanism also includes a centering spring, the driven column and the hollow column are coaxial, the driven column is axially slidably installed inside the hollow column, the centering spring is arranged between the hollow column and the driven column, and the centering spring is slidably installed on the driven column. The cam column rotates, and under the limiting effect of the annular groove, the driving protrusion slides on the axial rail; when the bottom of the driven column contacts the bottom of the filter housing, the cam column continues to drive the active column to move downward through the protrusion, and relative sliding occurs between the hollow column and the driven column, the centering spring is compressed, and the angle between the connecting rod and the adjusting component changes, so that the polishing component of the polishing mechanism, the main polisher and the inner wall of the filter housing are in close contact.

[0006] Furthermore, the cam column is sleeved on the outside of the active column, the cam column and the active column are coaxial, the cam column and the support plate column are coaxial, and the axial height of the annular groove is greater than the diameter of the convex column. When the convex column slides to the annular groove, the cam column continues to rotate, driving the convex column to slide inside the annular groove, so that the active column rotates inside the support plate column, and the filter housing is centered under the action of multiple groups of adjustment mechanisms. The filter housing is coaxial with the active column, and when the active column rotates, it drives the polishing mechanism to polish the inside of the filter housing.

[0007] Furthermore, the adjustment assembly includes an adjustment rod and a hollow rod, the hollow rod is rotatably mounted on the ear pin at the bottom of the driven column, the adjustment rod is slidably mounted inside the adjustment rod, an adjustment spring is arranged between the adjustment rod and the hollow rod, and the end of the adjustment rod is rotatably mounted with the connecting rod. When the polishing mechanism contacts the inner wall of the filter housing, as the distance between the driven column and the hollow column decreases, the centering spring is compressed, and the adjustment spring adjusts the relative position of the adjustment rod and the hollow rod to ensure that when the convex column slides to the annular groove, the driven column and the filter housing are coaxial, and the polishing mechanism is in close contact with the inner wall of the filter housing, which is convenient for the polishing mechanism to perform polishing.

[0008] Furthermore, the polishing assembly includes a slave polisher and a polishing rod. The end of the slave polisher is rotatably mounted with the end of the main polisher. The teeth of the slave polisher and the teeth of the main polisher are engaged with each other. A polishing block is slidably mounted on the rectangular rail of the connecting rod. The polishing rod is rotatably mounted on the polishing block. The polishing rod is slidably mounted with the sliding rod of the slave polisher. The position of the polishing block on the rectangular rail is adjusted to adapt to the curvature of the bottom and side wall of the filter housing, so that the main polisher, the slave polisher and the connection between the bottom and side wall of the filter housing are in close contact, thereby improving the polishing effect.

[0009] Furthermore, the polishing mechanism also includes a positioning assembly, which includes a positioning plate and a positioning spring. A pin seat is provided on the slide bar, a positioning plate is provided above the pin seat, a positioning rod is fixedly installed on the positioning plate, the positioning rod is slidably installed on the pin seat, a positioning spring is provided between the bottom of the positioning rod and the pin seat, the positioning spring is slidably installed on the positioning rod, a positioning hole is provided on the polishing rod, and the bottom of the positioning rod is in contact with the positioning hole. The bottom of the positioning rod is in contact with the positioning hole to limit the relative position of the polishing rod and the slide bar, and is in cooperation with the position of the polishing block on the rectangular rail, thereby increasing the adjustable range of the angle between the main polisher and the slave polisher, thereby better making the main polisher, the slave polisher and the connection between the bottom and the side wall of the filter housing in close contact, and improving the polishing effect.

[0010] Furthermore, the polishing mechanism also includes a limit assembly, which includes a limit plate and a limit spring. Two groups of limit rods are fixedly installed on the limit plate. The limit rod is slidably installed on the rectangular groove of the connecting rod. The limit spring is arranged between the polishing block and the bottom of the limit rod. The limit spring is slidably installed on the limit rod. A limit column is arranged on the limit plate. A limit hole is arranged on the polishing block. The main polisher is provided with multiple groups of limit grooves. The limit column contacts and cooperates with the limit hole and the limit groove. The limit column contacts and cooperates with the limit hole and the limit groove to limit the position of the polishing block on the connecting rod, adjust the position of the polishing block on the connecting rod, apply an upward force to the limit plate, the limit spring is compressed, the limit column disconnects the contact with the limit groove and the limit hole, adjusts the polishing block to the target position, disconnects the force applied to the limit plate, and the position of the polishing block is fixed, thereby changing the angle and spatial dimension of the main polisher and the slave polisher, improving the contact effect of the main polisher, the slave polisher and the connection between the bottom and the side wall of the filter housing, thereby improving the polishing effect.

[0011] Furthermore, the power mechanism includes a driven gear and a gear assembly. The driven gear is coaxial with the cam column, the driven gear is fixedly installed with the cam column, and the gear assembly is rotatably installed on the top of the support plate column. The gear assembly includes an incomplete pinion and an incomplete internal gear. A gear rack is fixedly connected between the incomplete pinion and the incomplete internal gear, and the gear rack is rotatably installed on the top of the support plate column. The incomplete internal gear and the incomplete pinion are respectively meshed with the driven gear. The rotation of the gear rack drives the incomplete internal gear and the incomplete pinion gear to rotate. When the incomplete internal gear meshes with the driven gear, the driven gear drives the cam column to rotate clockwise, and the convex column of the active column slides toward the annular groove on the axial rail and the arc rail. During this process, the active column and the driven column drive the adjusting mechanism to contact the side wall of the filter housing until the convex column slides into the inside of the annular groove, and the cam column drives the active column to make a circular motion inside the support plate column. At this time, the active column and the driven column, with the assistance of the adjusting mechanism, the polishing mechanism is in close contact with the bottom and side wall of the filter housing, and the bottom and side wall of the filter housing are polished; when the incomplete internal gear is disconnected from the driven gear, the incomplete pinion gear meshes with the driven gear, driving the driven gear to drive the cam column to rotate counterclockwise. At this time, under the elastic action of the arc rail and the centering spring, the convex column of the active column is pushed from the annular groove to the axial rail, so that the convex column drives the active column to move away from the annular groove, the centering spring stretches, and as the active column moves upward, the driven column and the adjusting mechanism are separated from the inside of the filter housing.

[0012] Furthermore, the center angle of the circle subtended by the teeth of the incomplete pinion is r, and the center angle of the circle subtended by the teeth of the incomplete internal gear is R, and R+r<360°. When the convex column of the active column slides to the top of the axial rail, the incomplete pinion is disengaged from the driven gear, and the incomplete internal gear is not engaged with the driven gear at this time, the gear rack continues to rotate, and the driven gear is in a stationary state, providing replacement time for the polished filter housing and the filter housing to be polished, thereby improving work efficiency and automation.
