Description

Technical Field

[0001] This utility model belongs to the field of honing rod technology, and specifically relates to a honing rod. Background Technology

[0002] A honing machine is a precision grinding machine that uses a honing head to reciprocate the rotation of the workpiece's inner hole, creating a cross-hatched surface to achieve micron-level dimensional correction (roundness error of keyless holes ≤0.003mm, roundness error of keyed holes ≤0.01mm, roughness Ra0.04-0.4μm). It is suitable for precision machining of automotive engine blocks, hydraulic valve holes, and other components. Its core component, the honing rod, consists of a rigid rod body, an expandable honing head, and a honing stone. The radial feed of the honing stone is controlled by a hydraulic or mechanical mechanism. It can process holes with diameters ranging from 8-500mm and is compatible with diamond / CBN abrasives, making it a viable alternative to imported equipment.

[0003] However, existing honing rods have the following problems: single-oilstone honing rods experience significant wear during internal hole machining; multi-oilstone honing rods exhibit poor tension transmission during internal hole machining. Poor tension transmission in honing rods can lead to the following consequences: 1) decreased machining accuracy; 2) deterioration of surface quality; 3) abnormal wear of the oilstone; 4) process stability issues. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a honing rod, which aims to solve the problems of easy wear and poor tension transmission effect of the existing honing rod.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A honing rod includes a rod body, a wedge, and two oilstones. The upper side of the rod body has a groove for placing the wedge. When the wedge is placed at the bottom of the groove, the wedge is completely aligned with the center line of the rod body. The wedge can move horizontally within the groove. The upper and lower sides of the honing section of the rod body have slots for placing the oilstones. The slots for placing the two oilstones are connected through the grooves.

[0007] The wedge has an upwardly inclined multi-level limiting notch at the lower left end of the honing section, and a downwardly inclined multi-level limiting notch at the upper right end of the honing section. The two oilstones extend into the groove and respectively cooperate with the multi-level limiting notches on both sides of the wedge.

[0008] The sides of the oilstone placement trough are all equipped with locking mechanisms, which are used to lock the oilstone and prevent it from falling off.

[0009] An adjustment mechanism is provided in the middle of the rod, which is used to adjust the fit and gap between the wedge and the rod.

[0010] Furthermore, the locking mechanism includes a spring and an adjusting screw disposed on the side of the oilstone placement groove, the adjusting screw being used to adjust the tension of the spring.

[0011] Furthermore, the adjustment mechanism includes a fixed sleeve fitted onto the rod body, the rod body having a positioning hole facing the groove, the fixed sleeve being fixedly connected to the rod body through the positioning hole and a fixing screw, and both ends of the upper side of the fixed sleeve being threaded with adjusting screws that extend into the groove, the adjusting screws and the fixing screws being perpendicular to each other with the groove.

[0012] Furthermore, a locking position is provided on the lower side of the rod.

[0013] Furthermore, the end of the wedge away from the whetstone extends out of the rod and is fixedly connected to a hook.

[0014] Beneficial effects:

[0015] 1. Compared with the traditional single oilstone honing rod, the honing rod of this utility model has oilstones on both the upper and lower sides, the contact surface between the oilstone and the product to be processed is larger, the product size and geometry are easier to adjust, and the wear on the rod body is less during processing.

[0016] 2. Compared with traditional honing rods with multiple oilstones, the honing rod of this utility model has more efficient tension transmission, a larger contact area between the oilstone and the wedge, and can adjust the relative position of the oilstone and the wedge on the upper and lower sides by moving the wedge, thus converting axial movement into radial expansion (converting axial pressure into radial tension).

[0017] 3. The honing rod of this utility model is equipped with a locking mechanism, including a spring and an adjusting screw, which can flexibly lock the honing stone, fixing the honing stone without damaging it.

[0018] 4. The honing rod of this utility model is suitable for machining internal holes other than blind holes, and is especially suitable for machining internal holes with keyways. Attached Figure Description

[0030] like Figures 1 to 8 As shown, this utility model discloses a honing rod, including a rod body 1, a wedge 2 and two oilstones 3. A groove for placing the wedge 2 is provided on the upper side of the rod body 1. When the wedge 2 is placed at the bottom of the groove, the wedge 2 and the center line of the rod body 1 are completely coincident. The wedge 2 can move horizontally in the groove. The honing section of the rod body 1 has a placement groove for placing the oilstones 3 on both the upper and lower sides. The placement grooves of the two oilstones 3 are connected through the groove.

[0031] The wedge 2 has an upwardly inclined multi-level limiting notch at the lower left end of the honing section, and a downwardly inclined multi-level limiting notch at the upper right end of the honing section. The two oilstones 3 have one end inserted into the groove and cooperate with the corresponding multi-level limiting notches on both sides of the wedge 2.

[0032] The sides of the oilstone 3 placement groove are equipped with locking mechanisms to lock the oilstone 3 and prevent it from falling off.

[0033] An adjustment mechanism is provided in the middle of the rod body 1. The adjustment mechanism is used to adjust the fit and gap between the wedge 2 and the rod body 1.

[0034] As a preferred embodiment, the locking mechanism includes a spring 4 and an adjusting screw 5 disposed on the side of the oilstone 3 placement groove, the adjusting screw 5 being used to adjust the tightness of the spring 4.

[0035] As a preferred embodiment, the adjustment mechanism includes a fixed sleeve 6 sleeved on the rod 1. The rod 1 has a positioning hole 7, which is directly opposite the groove. The fixed sleeve 6 is fixedly connected to the rod 1 through the positioning hole 7 and the fixing screw 8.

[0036] As a preferred embodiment, a locking slot 10 is provided on the lower side of the rod 1, which facilitates the honing machine to lock and fix the rod 1.

[0037] As a preferred embodiment, the end of the wedge 2 away from the oilstone 3 extends out of the rod body 1 and is fixedly connected to a hook 11. This facilitates the movement of the wedge 2 within the groove by pulling it with the hook 11, thereby adjusting the relative position of the wedge 2 and the two oilstones 3.

[0038] The process of using this honing rod is as follows:

[0039] First, select a suitable whetstone 3 based on the product to be processed. Then, install two whetstones 3 into the placement slots on the upper and lower sides of the rod 1, respectively. The opposite ends of the two whetstones 3 extend into the grooves and engage with the corresponding multi-stage limiting notches on the wedge 2. Next, adjust the relative positions of the wedge 2 and the whetstones 3 as needed. Use the hook 11 to pull the wedge 2 to the left within the groove. The wedge 2, through the multi-stage limiting notches on both sides, engages with the two whetstones 3, converting axial movement into radial expansion (converting axial pressure into radial tension). After the two whetstones 3 reach the target position, stop the movement of the wedge 2 and tighten the adjusting screws 9 at both ends of the fixing sleeve 6. The adjusting screws 9 extend into the grooves to abut and fix the wedge 2. After the wedge 2 is fixed, adjust the tension of the spring 4 using the adjusting screw 5, allowing the spring 4 to flexibly lock the whetstones 3 in the placement slots. During subsequent use, the whetstones 3 can be adjusted or replaced as needed.
