Description

Technical Field

[0001] The invention belongs to the technical field of diesel engine processing, and in particular relates to a tool and a method for removing burrs from cross holes. Background Art

[0002] The main oil channel of the diesel engine cylinder block is the main oil channel hole of the lubrication system. There are oblique oil holes that divert to the main bearing hole and camshaft hole. These oblique oil holes intersect with the main oil channel hole, and burrs will appear at the intersection. If these burrs are not removed, they will be brought into the main bearing hole during the operation of the diesel engine, causing the crankshaft and main bearing bushing to wear sharply and burn, seriously affecting the performance and life of the diesel engine.

[0003] The most commonly used methods for removing burrs from the intersecting areas of the main oil channel holes are electrolytic deburring, using special cross-hole deburring tools to remove burrs from the oil holes that intersect with the main oil channel, using high-pressure water flushing, and manual removal methods such as inserting an abrasive brush into the main oil channel holes and oblique oil holes and repeatedly brushing them.

[0004] However, the electrolytic deburring method uses sodium nitrate and other chemicals as electrolytes, which are toxic and easily pollute the environment; the use of a special deburring cross hole tool to remove the burrs from the oil holes intersecting the main oil channel is expensive, and the two intersecting holes are required to be orthogonal (the center lines of the holes intersect). If the center line eccentricity of the cross hole is greater, the burrs at the intersection cannot be removed by the tool; the method of flushing with high-pressure water flow is unreliable, and the high-pressure pump that generates high-pressure water is easily damaged; the manual removal method of inserting an abrasive brush into the main oil channel hole and the oblique oil hole and brushing it repeatedly requires manual operation, is labor-intensive, and has poor consistency.

[0005] Therefore, it is urgent to provide a tool and method for removing cross hole burrs to solve the above problems. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a tool and method for removing burrs from cross holes.

[0007] The technical solution adopted to solve the above technical problem is: to provide a tool and method for removing burrs from cross holes, including a core rod, a front end of which is detachably mounted with a plurality of deburring mechanisms;

[0008] The deburring mechanism comprises a compression spring, connecting plates are fixedly mounted at both ends of the compression spring, a steel ball is movably placed on the surface of the connecting plate, a clamping mechanism for clamping the steel ball is provided on the surface of the connecting plate, and a locking mechanism for locking the clamping mechanism is provided on the surface of the connecting plate;

[0009] A limiting mechanism is detachably mounted on the surface of the core rod, and a bolt is threadedly connected to the connection between the limiting mechanism and the core rod.

[0010] The present invention is further configured as follows: the core rod includes a clamping section, a supporting section is fixedly installed at one end of the clamping section, a working section is fixedly installed at one end of the supporting section, a plurality of first through holes are opened on the surface of the working section, and the deburring mechanism is detachably installed inside the first through hole.

[0011] Through the above technical scheme, when the device is used, the clamping section can be installed on the knife handle or the air gun, the length of the supporting section determines the length by which the device can be extended and retracted inside the diesel engine cylinder, the deburring mechanism is placed in the first through hole inside the working section and can follow the working section into the diesel engine cylinder to perform deburring work, the device enters the main oil channel from the main oil hole, and under the action of the compression spring, the connecting plate drives the steel ball to pop out from the second through hole, the upper part of the steel ball is higher than the surface of the limit sleeve, and through rotation, the burrs at the intersection of each oil hole and the main oil channel hole are struck, so that the burrs fall off and the burrs are removed cleanly, and the burrs are removed by the method of the steel ball popping out and striking the burrs off.

[0012] The present invention is further configured as follows: the first through holes are configured as five groups, three groups of the first through holes are distributed in a horizontal direction, two groups of the first through holes are distributed in a vertical direction, a group of first through holes in a vertical direction is arranged between two adjacent horizontal first through holes, and the distance between two adjacent first through holes is consistent.

[0013] Through the above technical solution, the positions of the first through holes are distributed at different locations, so that the position of the deburring mechanism can be fixed. When the device is extended into the diesel engine cylinder, the deburring mechanism in the vertical and horizontal directions can deburr the corresponding oil channel holes inside the cylinder through rotation.

[0014] The present invention is further configured as follows: the limiting mechanism includes a limiting sleeve, the limiting sleeve is movably sleeved on the surface of the working section, the inner diameter of the limiting sleeve is consistent with the outer diameter of the working section, a plurality of second through holes are opened on the surface of the limiting sleeve, the inner diameter of the second through hole is smaller than the inner diameter of the first through hole, and the diameter of the steel ball is smaller than the inner diameters of the first through hole and the second through hole.

[0015] Through the above technical scheme, the limit sleeve protects the working section. At the same time, a second through hole corresponding to the first through hole is provided on the surface of the limit sleeve. The steel ball can move inside the first through hole, and the second through hole limits the steel ball so that the upper part of the steel ball can extend to the outside of the limit sleeve. The steel ball exceeding the surface of the limit sleeve is used for deburring.

[0016] The present invention is further configured as follows: the second through holes are configured as five groups, the distribution positions of the second through holes are consistent with those of the first through holes, a straight groove is provided at the front end of the limit sleeve, an extension block is fixedly installed at the front end of the working section, and the extension block is slidably connected inside the straight groove.

[0017] Through the above technical solution, the distribution positions of the first through hole and the second through hole are consistent, thereby ensuring that the upper part of the steel ball can extend out of the surface of the limit sleeve. When the limit sleeve is arranged on the surface of the working section, the extension block is inserted into the straight groove to fix the angle of the core rod, thereby ensuring that the first through hole and the second through hole are always connected to each other.

[0018] The present invention is further configured as follows: screw holes are provided on the surface of the extension block and the front end surface of the limiting sleeve, bolts are threadedly connected inside the screw holes, and the bolts are hexagon socket head screws.

[0019] Through the above technical solution, the bolts are inserted into the screw holes on the extension block and the surface of the limit sleeve, so that the limit sleeve can be stably mounted on the surface of the working section, thereby preventing the limit sleeve from detaching from the surface of the working section during the deburring work, causing the deburring mechanism to slip out of the first through hole and remain inside the diesel engine cylinder.

[0020] The present invention is further configured as follows: the clamping mechanism includes two clamping blocks, the two clamping blocks are slidably connected to the surface of the connecting plate, a plurality of protrusions are fixedly installed on the surface of the clamping block, the protrusions are movably fitted with the surface of the steel ball, and the shape of the clamping block is a quarter of a spherical shell.

[0021] Through the above technical solution, the surface of the steel ball is prone to wear during long-term deburring work, which affects the subsequent deburring effect. Therefore, the steel ball needs to be replaced regularly. When replacing a new steel ball, the two clamping blocks move toward each other to clamp the surface of the steel ball. The clamping block is set in a quarter spherical shell to wrap the lower part of the steel ball. The friction between the clamping block and the surface of the steel ball is further increased through the convex points inside the clamping block, thereby improving the clamping effect.

[0022] The present invention is further configured as follows: a bidirectional screw is rotatably connected inside the connecting plate, a symmetrical screw sleeve is threadedly connected on the surface of the bidirectional screw, connecting rods are fixedly installed on the surfaces of the two screw sleeves, the two connecting rods are respectively fixedly connected to the lower surfaces of the two clamping blocks, symmetrical connecting rod grooves are opened on the surface of the connecting plate, the connecting rods are slidably connected inside the connecting rod grooves, and symmetrical screw sleeve grooves are opened inside the connecting plate, and the screw sleeves are slidably connected inside the screw sleeve grooves.

[0023] Through the above technical solution, when the bidirectional screw rotates clockwise, the two screw sleeves move toward each other, and further drive the two clamping blocks to move toward each other through the connecting rod, so as to effectively fix the lower part of the steel ball. When a new steel ball needs to be replaced, the bidirectional screw rod is rotated counterclockwise to move the two clamping blocks away from each other. After taking out the worn steel ball, the bidirectional screw rod is rotated clockwise again, and the clamping blocks re-clamp the steel ball. Through the setting of the connecting rod groove and the screw sleeve groove, the connecting rod and the screw sleeve can be more stable when moving left and right.

[0024] The present invention is further configured as follows: the locking mechanism includes a rotating handle, the rotating handle is rotatably connected to the surface of the connecting plate, a first bevel gear is fixedly installed on one end of the bidirectional screw rod, a rotating rod is fixedly installed on the lower surface of the rotating handle, a second bevel gear is fixedly installed on the end of the rotating rod, the first bevel gear is meshed with the second bevel gear, a pin is movably inserted inside the rotating handle, a plurality of sockets are opened on the surface of the connecting plate, and the pin is movably inserted inside the sockets.

[0025] Through the above technical solution, when the handle is rotated, the rotating rod rotates, thereby rotating the second bevel gear, and the first bevel gear at the end of the two-way screw rod engages with the second bevel gear, so that the two-way screw rod can follow the rotation to move the clamping block. To ensure that the two-way screw rod reverses after the clamping block clamps the steel ball, the pin is inserted into the socket on the surface of the connecting plate to fix the rotating handle, so that the clamping block can stably clamp the steel ball.

[0026] A method for removing cross hole burrs from a tool, comprising the following steps:

[0027] Step 1: Install the tool on the tool handle or air gun, and drive the tool handle or air gun to clamp the core rod through the machining center;

[0028] Step 2: Rotate the core rod and extend it into the main oil channel. When passing through the main oil channel entity section, the steel balls are pressed by the inner wall of the main oil channel, and the highest points of the two steel balls controlled by each compression spring fit the inner wall of the main oil channel.

[0029] Step 3: When the steel ball runs to the cross hole, the steel ball will pop out under the recovery action of the compression spring. The two steel balls controlled by each compression spring extend into the cross hole to hit the burrs around the cross hole.

[0030] Step 4: Hold the core rod and rotate the tool for deburring cross holes repeatedly. The steel ball pops out repeatedly to hit the burrs around the cross holes, and finally the burrs are removed completely.

[0031] The beneficial effects of the present invention are as follows: (1) The present invention is provided with a deburring mechanism, and the device enters the main oil channel from the main oil hole. Under the action of the compression spring, the connecting plate drives the steel ball to pop out from the second through hole. The upper part of the steel ball is higher than the surface of the limit sleeve. By rotating, the burrs at the intersection of each oil hole and the main oil channel hole are struck, so that the burrs fall off and the burrs are removed cleanly. The burrs are removed by the method of ejecting the steel ball to knock the burrs off. It can be operated manually or on equipment, with low cost, high efficiency and no pollution to the environment. (2) During long-term deburring work, the surface of the steel ball is prone to wear and affect the subsequent deburring effect. Therefore, the steel ball needs to be replaced regularly. When replacing a new steel ball, two clamping blocks move toward each other to clamp the surface of the steel ball. The clamping block is arranged in a quarter spherical shell to wrap the lower part of the steel ball. The convex points inside the clamping block further increase the friction between the clamping block and the surface of the steel ball, thereby improving the clamping effect.

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] See also Figure 1-Figure 6 , the present application provides a tool and method for removing burrs from a cross hole, comprising a core rod 1, a front end of which is detachably mounted with a plurality of deburring mechanisms 2;

[0041] like Figure 2 As shown, the core rod 1 includes a clamping section 11, a supporting section 12 is fixedly installed at one end of the clamping section 11, a working section 13 is fixedly installed at one end of the supporting section 12, a plurality of first through holes 14 are opened on the surface of the working section 13, and the deburring mechanism 2 is detachably installed inside the first through holes 14.

[0042] In this embodiment: when the device is used, the clamping section 11 can be installed on a knife handle or an air gun, the length of the support section 12 determines the length by which the device can be extended and retracted inside the diesel engine cylinder, the deburring mechanism 2 is placed in the first through hole 14 inside the working section 13 and can follow the working section 13 into the diesel engine cylinder to perform deburring work, the device enters the main oil channel from the main oil hole, and under the action of the compression spring 21, the connecting plate 22 drives the steel ball 23 to pop out from the second through hole 32, and the upper part of the steel ball 23 is higher than the surface of the limit sleeve 31. By rotating, the burrs at the intersection of each oil hole and the main oil channel hole are struck, so that the burrs fall off and the burrs are removed cleanly, and the burrs are removed by the method of the steel ball 23 popping out and striking the burrs off.

[0043] like Figure 2 As shown, the first through holes 14 are arranged in five groups, three groups of first through holes 14 are distributed in the horizontal direction, two groups of first through holes 14 are distributed in the vertical direction, a group of first through holes 14 in the vertical direction is arranged between two adjacent horizontal first through holes 14, and the distance between two adjacent first through holes 14 is consistent.

[0044] In this embodiment: the first through holes 14 are distributed at different positions, so that the position of the deburring mechanism 2 can be fixed. When the device is extended into the diesel engine cylinder, the deburring mechanism 2 in the vertical and horizontal directions can deburr the corresponding oil channel holes inside the cylinder through rotation.

[0045] The deburring mechanism 2 includes a compression spring 21, with connecting plates 22 fixedly installed at both ends of the compression spring 21, a steel ball 23 movably placed on the surface of the connecting plate 22, a clamping mechanism 5 for clamping the steel ball 23 is provided on the surface of the connecting plate 22, and a locking mechanism 6 for locking the clamping mechanism 5 is provided on the surface of the connecting plate 22.

[0046] like Figure 6 As shown, the clamping mechanism 5 includes two clamping blocks 51, which are slidably connected to the surface of the connecting plate 22. A plurality of protrusions 52 are fixedly mounted on the surface of the clamping block 51, and the protrusions 52 are movably fitted with the surface of the steel ball 23. The shape of the clamping block 51 is a quarter spherical shell.

[0047] In this embodiment: during long-term deburring work, the surface of the steel ball 23 is easily worn and affects the subsequent deburring effect. Therefore, the steel ball 23 needs to be replaced regularly. When replacing a new steel ball 23, the two clamping blocks 51 move toward each other to clamp the surface of the steel ball 23. The clamping block 51 is configured as a quarter spherical shell to wrap the lower part of the steel ball 23. The protrusions 52 inside the clamping block 51 further increase the friction between the clamping block 51 and the surface of the steel ball 23, thereby improving the clamping effect.

[0048] like Figure 6 As shown, a bidirectional screw rod 53 is rotatably connected inside the connecting plate 22, and a symmetrical screw sleeve 54 is threadedly connected on the surface of the bidirectional screw rod 53. Connecting rods 55 are fixedly installed on the surfaces of the two screw sleeves 54. The two connecting rods 55 are respectively fixedly connected to the lower surfaces of the two clamping blocks 51. Symmetrical connecting rod grooves 57 are opened on the surface of the connecting plate 22, and the connecting rod 55 is slidably connected inside the connecting rod grooves 57. Symmetrical screw sleeve grooves 56 are opened inside the connecting plate 22, and the screw sleeve 54 is slidably connected inside the screw sleeve grooves 56.

[0049] In this embodiment: when the bidirectional screw rod 53 rotates clockwise, the two screw sleeves 54 move toward each other, and further drive the two clamping blocks 51 to move toward each other through the connecting rod 55, so as to effectively fix the lower part of the steel ball 23. When a new steel ball 23 needs to be replaced, the bidirectional screw rod 53 is rotated counterclockwise to move the two clamping blocks 51 away from each other. After the worn steel ball 23 is taken out, the bidirectional screw rod 53 is rotated clockwise again, and the clamping blocks 51 clamp the steel ball 23 again. By setting the connecting rod groove 57 and the screw sleeve groove 56, the connecting rod 55 and the screw sleeve 54 can be more stable when moving left and right.

[0050] like Figure 6 As shown, the locking mechanism 6 includes a rotating handle 61, which is rotatably connected to the surface of the connecting plate 22, a first bevel gear 58 is fixedly installed on one end of the bidirectional screw rod 53, a rotating rod 62 is fixedly installed on the lower surface of the rotating handle 61, and a second bevel gear 63 is fixedly installed on the end of the rotating rod 62, the first bevel gear 58 is meshed with the second bevel gear 63, a pin 64 is movably inserted inside the rotating handle 61, and a plurality of sockets 65 are opened on the surface of the connecting plate 22, and the pin 64 is movably inserted inside the socket 65.

[0051] In this embodiment: when the rotating handle 61 is rotated, the rotating rod 62 rotates, thereby rotating the second bevel gear 63, and the first bevel gear 58 at the end of the bidirectional screw rod 53 engages with the second bevel gear 63, so that the bidirectional screw rod 53 can follow the rotation to move the clamping block 51. To ensure that the bidirectional screw rod 53 reverses after the clamping block 51 clamps the steel ball 23, the pin 64 is inserted into the socket 65 on the surface of the connecting plate 22 to fix the rotating handle 61, so that the clamping block 51 can stably clamp the steel ball 23.

[0052] A limiting mechanism 3 is detachably mounted on the surface of the core rod 1 , and a bolt 4 is threadedly connected to the connection between the limiting mechanism 3 and the core rod 1 , and the bolt 4 is a hexagon socket head screw.

[0053] like Figure 4 As shown, the limiting mechanism 3 includes a limiting sleeve 31, which is movably sleeved on the surface of the working section 13, the inner diameter of the limiting sleeve 31 is consistent with the outer diameter of the working section 13, and a plurality of second through holes 32 are opened on the surface of the limiting sleeve 31, the inner diameter of the second through holes 32 is smaller than the inner diameter of the first through holes 14, and the diameter of the steel ball 23 is smaller than the inner diameters of the first through holes 14 and the second through holes 32.

[0054] In this embodiment: the limiting sleeve 31 protects the working section 13, and at the same time, a second through hole 32 corresponding to the first through hole 14 is provided on the surface of the limiting sleeve 31. The steel ball 23 can move inside the first through hole 14, and the second through hole 32 limits the steel ball 23, so that the upper part of the steel ball 23 can extend to the outside of the limiting sleeve 31, and the steel ball 23 beyond the surface of the limiting sleeve 31 is used for deburring.

[0055] like Figure 4 As shown, the second through holes 32 are arranged in five groups, and the distribution positions of the second through holes 32 and the first through holes 14 are consistent. A straight groove 33 is provided at the front end of the limiting sleeve 31, and an extension block 15 is fixedly installed at the front end of the working section 13, and the extension block 15 is slidably connected inside the straight groove 33.

[0056] In this embodiment: the distribution positions of the first through hole 14 and the second through hole 32 are consistent, thereby ensuring that the upper part of the steel ball 23 can extend out of the surface of the limit sleeve 31. When the limit sleeve 31 is sleeved on the surface of the working section 13, the extension block 15 is inserted into the straight groove 33 to fix the angle of the core rod 1, thereby ensuring that the first through hole 14 and the second through hole 32 always remain in a connected state.

[0057] like Figure 5 As shown, screw holes 34 are provided on the surface of the extension block 15 and the front end surface of the limiting sleeve 31 , and bolts 4 are threadedly connected inside the screw holes 34 .

[0058] In this embodiment: the bolt 4 is inserted into the screw hole 34 on the surface of the extension block 15 and the limit sleeve 31, so that the limit sleeve 31 can be stably sleeved on the surface of the working section 13, avoiding the limit sleeve 31 from detaching from the surface of the working section 13 during the deburring work, causing the deburring mechanism 2 to slip out of the first through hole 14 and remain in the diesel engine cylinder.

[0059] A method for removing cross hole burrs from a tool, comprising the following steps:

[0060] Step 1: Install the tool on the tool handle or air gun, and drive the tool handle or air gun to clamp the core rod 1 through the machining center;

[0061] Step 2: Rotate the core rod 1 and extend it into the main oil channel. When passing through the main oil channel entity section, the steel balls 23 are pressed by the inner wall of the main oil channel, and the highest points of the two steel balls 23 controlled by each compression spring 21 fit the inner wall of the main oil channel.

[0062] Step 3: When the steel ball 23 runs to the cross hole, the steel ball 23 will pop out under the restoring action of the compression spring 21, and the two steel balls 23 controlled by each compression spring 21 extend into the cross hole to hit the burrs around the cross hole;

[0063] Step 4: Hold the core rod 1 and repeatedly rotate the tool for removing the cross hole burrs. The steel ball 23 repeatedly pops out to hit the burrs around the cross hole, and finally the burrs are completely removed.

[0064] The working principle of this embodiment is as follows: the tool is installed on the tool handle or the air gun, and the clamping core rod 1 on the tool handle or the air gun is driven by the machining center to rotate and extend into the main oil channel. When passing through the main oil channel entity section, the steel ball 23 is pressed by the inner wall of the main oil channel, and the highest points of the two steel balls 23 controlled by each compression spring 21 are in contact with the inner wall of the main oil channel. When the steel ball 23 runs to the cross hole, the steel ball 23 will pop out under the restoring action of the compression spring 21. The two steel balls 23 controlled by each compression spring 21 extend to the inside of the cross hole, and can hit the burrs around the cross hole to make them fall off. By repeatedly rotating the tool for removing the burrs from the cross hole, the steel ball 23 repeatedly pops out to hit the burrs around the cross hole, and finally the burrs are removed cleanly. When the steel ball 23 is in long-term deburring work, the surface is prone to wear and affect The subsequent deburring effect is affected, so the steel ball 23 needs to be replaced regularly. When replacing a new steel ball 23, the rotating handle 61 is rotated clockwise, the rotating rod 62 rotates, the second bevel gear 63 rotates accordingly, and the first bevel gear 58 at the end of the two-way screw rod 53 meshes with the second bevel gear 63, so that the two-way screw rod 53 rotates clockwise, and the two clamping blocks 51 move away from each other. After taking out the worn steel ball 23, the rotating handle 61 is rotated counterclockwise again. The two-way screw rod 53 rotates counterclockwise to drive the two screw sleeves 54 to move toward each other, and drive the two clamping blocks 51 to re-clamp the new steel ball 23. The clamping block 51 is set as a quarter spherical shell to wrap the lower part of the steel ball 23, and the friction between the clamping block 51 and the surface of the steel ball 23 is further increased through the convex point 52 inside the clamping block 51.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
