Description

Technical Field

[0001] The utility model relates to the technical field of oil pump cam processing, in particular to an oil pump cam burr removal device. Background Art

[0002] The existing oil pump cam is processed by grinding, which will produce burrs on the oil pump cam after processing. Therefore, a deburring device is often required to deal with the burrs.

[0003] A burr removal device for an oil pump cam is disclosed in Chinese patent publication number CN222078832U. The burr removal device for the oil pump cam can drive a grinding roller to move upward or downward by driving a second motor to rotate, so as to grind the sides of the oil pump cam at different positions, thereby removing burrs more thoroughly. However, according to the burr removal device and existing technology provided in the relevant field, traditional grinding equipment can usually only grind the outer surface of the cam. The camshaft and the side are not processed, resulting in functional hidden dangers. The burrs on the journal cause the bearing installation to get stuck, affecting the rotation accuracy of the camshaft. The burrs on the side may scratch the mating surface during the relative movement of the cam and the tappet or piston, shortening the life of the oil pump. The burrs on the side of the high-pressure oil pump cam may cause fuel leakage. In order to deal with the parts not covered by traditional equipment, additional processes such as journal grinders and side deburring tooling are required. Utility Model Content

DETAILED DESCRIPTION

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0030] like Figures 1 to 11 As shown, a burr removal device for an oil pump cam is provided, which includes a workbench 1, on which a grinding assembly 2 for removing burrs from the oil pump cam and a regulating assembly 3 for clamping the oil pump cam and controlling its rotation are slidably provided. The workbench 1 is provided with a first regulating assembly 4 for controlling the left and right movement of the grinding assembly 2, and the workbench 1 is provided with a second regulating assembly 5 for controlling the forward and backward movement of the regulating assembly 3; the grinding assembly 2 includes a first bracket 201 slidably arranged on the top of the workbench 1, a first motor 202 is fixedly mounted on the first bracket 201, an output end of the first motor 202 passes through one end of the first bracket 201 and is fixedly mounted with a rotating shaft 203, and two grinding wheels 204 are symmetrically slidably provided on the outer surface of the rotating shaft 203; a driving member 6 for controlling the two grinding wheels 204 to approach or move away from each other is provided on the rotating shaft 203, and a stepless limiting assembly 7 is provided at one end of the driving member 6 located outside the rotating shaft 203, and the stepless limiting assembly 7 cooperates with the rotating shaft 203 to limit the operation of the driving member 6.

[0031] like Figure 4 、 Figure 9 、 Figure 10 and Figure 11 As shown, a through hole compatible with the rotating shaft 203 is opened at the center of the grinding wheel 204, and a cross-shaped piece 2041 is fixedly provided on the inner wall of the through hole. A sliding groove 2031 is opened at the position where the rotating shaft 203 corresponds to the connection between the cross-shaped piece 2041 and the grinding wheel 204. The driving member 6 is a left-handed threaded rod, and the driving member 6 is rotatably set at the center of the rotating shaft 203. The two cross-shaped pieces 2041 are respectively threadedly connected to the two threaded areas of the driving member 6.

[0032] In summary:

[0033] When the driving member 6 rotates, the cross-shaped member 2041 is used to cooperate with the thread of the driving member 6 to control the two grinding wheels 204 to move closer to or away from each other, so that the grinding wheels 204 can grind the cam shaft simultaneously or separately (the grinding wheels 204 rotate and grind close to the surface of the shaft body), the outer surface of the cam (the grinding wheels 204 move along the cam profile curve) and the side of the cam (by adjusting the spacing between the grinding wheels 204, the wheel rim is made to fit the side for transverse grinding), reducing the number of workpiece turnovers and avoiding positioning errors caused by traditional multi-step processing.

[0034] When controlling the spacing between the grinding wheels 204, the relative position of the two wheels can be changed to form different modes such as "parallel grinding" and "angle grinding":

[0035] Parallel mode: suitable for uniform grinding of camshafts and symmetrical cam sides;

[0036] Angle mode: Suitable for profiling grinding of cam profile surfaces or asymmetrical sides.

[0037] By using the driving member 6 of the left-hand and right-hand threaded rod, the distance between the two grinding wheels 204 can be accurately controlled, and cams of different widths can be adapted. Through "stepless adjustment", one machine can be used for multiple purposes, reducing equipment procurement costs and changeover time.

[0038] like Figure 4 、 Figure 6 、 Figure 7 and Figure 8As shown, the stepless limit assembly 7 includes a fixed shaft 701 fixedly arranged at the end of the driving member 6, a plurality of grooves 702 are provided on the outer surface of the fixed shaft 701, and movable blocks 703 are slidably provided inside the grooves 702. An oil cavity 704 containing hydraulic oil is provided at the center of the fixed shaft 701, and a connecting cavity 705 is provided between the fixed shaft 701 corresponding to the plurality of grooves 702 and the oil cavity 704. The grooves 702 are connected to the oil cavity 704 through the connecting cavity 705, and the movable block 703 is fixedly provided with a first movable block 703 at the position corresponding to the connecting cavity 705. Plug 706, the first piston 706 is slidably arranged inside the connecting chamber 705, and the second piston 707 is slidably arranged inside the oil chamber 704. The second piston 707 is rotatably provided with a screw rod 708 at one end toward the outside of the fixed shaft 701, and a knob 709 is fixedly provided at the end of the screw rod 708 away from the second piston 707. A threaded hole corresponding to the position of the fixed shaft 701 corresponding to the screw rod 708 is provided. A plurality of engaging teeth 2032 are fixedly provided on the inner wall of the rotating shaft 203 near one end of the fixed shaft 701, and the material of the movable block 703 is rubber.

[0039] In summary:

[0040] When the spacing between the two grinding wheels 204 is adjusted, the screw rod 708 is rotated in the opposite direction by turning the knob 709 so that the screw rod 708 drives the second piston 707 to move toward the inside of the fixed shaft 701, and then the hydraulic oil is used to make the first piston 706 drive the movable block 703 to be ejected to the outside of the groove 702, so that the movable block 703 is engaged with part of the engaging teeth 2032, so that the position can be locked at any rotation angle of the driving member 6, avoiding the spacing control error caused by the gear interval of the traditional "gear type limit". After locking, the rotating shaft 203 and the grinding wheel 204 form a rigid structure to avoid radial runout during high-speed rotation and prevent burr residue or surface scratches caused by vibration.

[0041] The regulating component 3 includes a second bracket 301 , a second motor 302 is fixedly mounted near the top of the second bracket 301 , and a three-jaw chuck 303 is fixedly mounted on the output end of the second motor 302 passing through one end of the second bracket 301 .

[0042] The first adjustment assembly 4 includes a first hydraulic cylinder 401 fixedly mounted on the top of the workbench 1, a first bracket 201 fixedly mounted on the output end of the first hydraulic cylinder 401, a first slide rail 402 fixedly mounted on one side of the top of the workbench 1 close to the first hydraulic cylinder 401, and the first bracket 201 slidingly cooperates with the first slide rail 402.

[0043] The second adjustment assembly 5 includes a second hydraulic cylinder 501 fixedly mounted on the top of the workbench 1, a second bracket 301 fixedly mounted on the output end of the second hydraulic cylinder 501, a second slide rail 502 fixedly mounted on one side of the top of the workbench 1 close to the second hydraulic cylinder 501, and the second bracket 301 slidingly cooperates with the second slide rail 502.

[0044] In summary:

[0045] First, when removing burrs, the three-jaw chuck 303 clamps one end of the oil pump cam, and then the second hydraulic cylinder 501 controls the second bracket 301 to slide, so that the regulating component 3 drives the oil pump cam to move toward one side of the grinding component 2;

[0046] Secondly, when the control assembly 3 moves to the designated position, the first motor 202 controls the rotation of the rotating shaft 203, and then the cross-shaped member 2041 cooperates with the slide groove 2031 to allow the two grinding wheels 204 to rotate synchronously with the rotating shaft 203, thereby removing burrs on the oil pump cam through the grinding wheels 204;

[0047] Third, the grinding assembly 2 can be controlled to move left and right by the first hydraulic cylinder 401, and the three-jaw chuck 303 can be controlled to rotate by the second motor 302, so that the outer surface of the grinding wheel 204 can grind the edge of the cam and the outer surface of the camshaft, and the side of the grinding wheel 204 can grind the side of the cam;

[0048] Fourthly, after grinding is completed, by shutting down the first motor 202 and the second motor 302, and then controlling the sliding of the second bracket 301 through the second hydraulic cylinder 501, the regulating component 3 can drive the oil pump cam to move to the side away from the grinding component 2. After moving to the specified position, the oil pump cam can be removed from the three-jaw chuck 303.

[0049] The working process is as follows:

[0050] S1: If Figures 4 to 7 As shown, during adjustment, the screw rod 708 is rotated by the knob 709 so that the screw rod 708 drives the second piston 707 to move toward the outside of the fixed shaft 701, and then the hydraulic oil is used to make the first piston 706 drive the movable block 703 to retract into the groove 702. At this time, the driving member 6 can be rotated through the fixed shaft 701;

[0051] S2: If Figures 1 to 5As shown, when the driving member 6 rotates, the cross-shaped member 2041 is threadedly engaged with the driving member 6 to control the two grinding wheels 204 to move closer to or farther from each other, so that the grinding wheels 204 can simultaneously or separately grind the cam shaft (the grinding wheels 204 rotate close to the shaft surface for grinding), the outer surface of the cam (the grinding wheels 204 move along the cam profile curve), and the side surfaces of the cam (by adjusting the spacing between the grinding wheels 204 so that the wheel rims are in contact with the side surfaces for transverse grinding), thereby reducing the number of workpiece turnovers and avoiding positioning errors caused by traditional multi-step processing;

[0052] S3: When controlling the distance between the grinding wheels 204, the relative position of the two wheels can be changed to form different modes such as "parallel grinding" and "angle grinding":

[0053] Parallel mode: suitable for uniform grinding of camshafts and symmetrical cam sides;

[0054] Angle mode: suitable for profiling grinding of cam profile surfaces or asymmetric sides;

[0055] Since the spacing between the two grinding wheels 204 is adjustable, the two grinding wheels 204 can be adjusted according to the spacing of the cams when grinding the outer surface of the camshaft. When it is necessary to grind between two adjacent cams, the spacing between the two grinding wheels 204 is adjusted so that a single grinding wheel 204 can be located between the two cams. Thus, when the grinding wheel 204 rotates circumferentially and slides axially, the grinding wheel 204 can contact the surface of the camshaft. Even if the cam spacings are different, since the spacing between the two grinding wheels 204 is adjustable, it can adapt to cams of various spacings, and there will be no interference between the two grinding wheels 204.

[0056] S4: By using the driving member 6 of the left-hand and right-hand threaded rod, the distance between the two grinding wheels 204 can be accurately controlled to adapt to cams of different widths. Through "stepless adjustment", one machine can be used for multiple purposes, reducing equipment procurement costs and changeover time.

[0057] S5: If Figure 4 、 Figure 6 、 Figure 7 and Figure 8 As shown, after the spacing between the two grinding wheels 204 is adjusted, the screw rod 708 is rotated in the opposite direction by the knob 709 so that the screw rod 708 drives the second piston 707 to move toward the inside of the fixed shaft 701, and then the hydraulic oil is used to make the first piston 706 drive the movable block 703 to be ejected to the outside of the groove 702, so that the movable block 703 is engaged with part of the engaging teeth 2032, so that the position can be locked at any rotation angle of the driving member 6, avoiding the spacing control error caused by the gear interval of the traditional "gear type limit". After locking, the rotating shaft 203 and the grinding wheel 204 form a rigid structure to avoid radial runout during high-speed rotation and prevent burr residue or surface scratches caused by vibration.

[0058] S6: As Figures 1 to 5 As shown, when removing burrs, one end of the oil pump cam is clamped by the three-jaw chuck 303, and then the second bracket 301 is controlled to slide by the second hydraulic cylinder 501, so that the regulating component 3 can drive the oil pump cam to move to one side of the grinding component 2;

[0059] S7: As Figure 1 、 Figure 4 、 Figure 9 and Figure 10 As shown, when the regulating assembly 3 moves to the designated position, the first motor 202 controls the rotation of the rotating shaft 203, and then the cross-shaped member 2041 cooperates with the slide groove 2031 to allow the two grinding wheels 204 to rotate synchronously with the rotating shaft 203, thereby removing burrs on the oil pump cam through the grinding wheels 204;

[0060] S8: Figures 1 to 5 As shown, the first hydraulic cylinder 401 can be used to control the grinding assembly 2 to move left and right, and the second motor 302 can control the three-jaw chuck 303 to rotate, so that the outer surface of the grinding wheel 204 can grind the edge of the cam and the outer surface of the camshaft, and the side of the grinding wheel 204 can grind the side of the cam (during grinding, the second motor 302 controls the three-jaw chuck 303 to rotate a certain angle, then stops. Then, when the grinding wheel 204 grinds one surface, the second motor 302 will control the three-jaw chuck 303 to rotate a certain angle again, and repeat this cycle to complete the grinding of the cam. At the same time, the second motor 302 can also control the three-jaw chuck 303 to drive the oil pump cam and the grinding wheel 204 to rotate in opposite directions to perform grinding and deburring work);

[0061] S9: As Figures 1 to 5 As shown, after grinding is completed, by shutting down the first motor 202 and the second motor 302, and then controlling the sliding of the second bracket 301 through the second hydraulic cylinder 501, the regulating component 3 can drive the oil pump cam to move to the side away from the grinding component 2. After moving to the specified position, the oil pump cam can be removed from the three-jaw chuck 303.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
