Description

Technical Field

[0001] The present invention relates to the technical field of engines, and particularly to a boring equipment for engine cylinder blocks. Background Art

[0002] Boring is a method for precision machining of the inner hole of a workpiece by a rotating cutting tool, mainly used for enlarging, trimming or improving the dimensional accuracy, shape accuracy and surface quality of the hole.

[0003] Chinese Patent with publication number CN216065638U discloses a special processing equipment for engine cylinder blocks; by arranging four rotating shafts and installing boring tools corresponding to four hole positions on the cylinder block that need to be bored, when performing boring processing, the four rotating shafts can be driven to penetrate into the corresponding four hole positions for one-time boring processing, effectively improving the processing efficiency of boring. At the same time, by arranging a cylinder block positioning component, the accuracy of the installation position of the cylinder block can be guaranteed, ensuring that the boring tool can accurately bore the hole position in the cylinder block, thereby ensuring the boring quality.

[0004] However, the above-mentioned prior art has the following defects: in order to ensure the rapid alignment of the boring tool with the hole position on the cylinder block (that is, to ensure that the axis of the boring bar coincides or is parallel to the axis of the target hole), the relative positions between the four rotating shafts are fixed and correspond one-to-one to the hole positions on a specific cylinder block, resulting in the above-mentioned prior art being only applicable to one specification of engine cylinder block. When facing cylinder blocks of different specifications, it is necessary to re-plan the relative positions between the four rotating shafts, resulting in a narrow application range of the above-mentioned prior art; in addition, before performing boring operations on the target hole on the cylinder block, it is necessary to clean the dirt such as residual chips and burrs inside the target hole, and the above-mentioned prior art cannot clean the target hole before boring operations.

Detailed implementation mode

[0020] Example 1, as Figures 1-4 and Figure 9 shown, a boring equipment for engine cylinder block proposed by the present invention includes a clamping and driving mechanism, a boring mechanism and a cleaning mechanism; The clamping and driving mechanism includes a frame 1, a clamping assembly and a transverse movement assembly; a chute a is provided on the frame 1; the clamping assembly is arranged inside the chute a for clamping the cylinder block; a chute b 101 is provided on the frame 1; the transverse movement assembly is arranged inside the chute b 101 and is connected with a sliding assembly, and the transverse movement assembly is used to drive the boring mechanism to move, so as to facilitate boring operations on target holes at different positions on the cylinder block; the sliding assembly enables the boring mechanism to move freely so as to quickly adapt to the target hole.

[0021] The boring mechanism includes a housing 14, a turntable 27, an outer ring plate 28, an expansion and support assembly, a boring tool 31, a plate a 12 and a driving assembly; the housing 14 is connected with the sliding assembly, and ventilation holes 1701 distributed in a circumferential manner are provided on the housing 14. The arrangement of the ventilation holes 1701 facilitates the heat dissipation of the equipment inside the housing 14 and at the same time ensures the normal operation of the fan 19; the housing 14 is detachably connected with the outer ring plate 28; the turntable 27 is rotatably arranged inside the outer ring plate 28; the expansion and support assembly is rotatably arranged on the turntable 27; a plurality of plate a 12 are distributed in a circumferential manner, and each plate a 12 is slidably connected with the turntable 27 and is connected with the expansion and support assembly at the same time; the boring tool 31 is detachably connected to the plate a 12, and the boring tool 31 is close to the bottom end position of the plate a 12; the detachable connection method includes but is not limited to connection by screws, which is convenient for the replacement of the boring tool 31; the driving assembly is arranged on the housing 14 and is connected with the turntable 27 for driving the boring tool 31 to rotate; The cleaning mechanism includes a shielding cover 8, a fan 19, a magnetic member 11, a telescopic member a21, a sliding cover 30 and an abrasive belt 13; the shielding cover 8 is slidably connected to the outer peripheral surface of the outer ring plate 28; the shielding cover 8 is provided with a circumferentially distributed air outlet, and a filter 801 is provided on the air outlet. The air outlet facilitates the rapid discharge of the air entering the shielding cover 8, and the filter 801 can filter the burrs and other dirt blown into the shielding cover 8; there are multiple magnetic members 11 distributed circumferentially and connected to the shielding cover 8, and the magnetic member 11 It includes a shell and an electromagnet, the shell is connected to the shielding cover 8, and the electromagnet is arranged on the inner side of the shell; there are multiple telescopic parts a21 distributed in a circle and connected to the turntable 27, the telescopic parts a21 include but are not limited to devices such as cylinders, the telescopic parts a21 are slidably connected to the sliding cover 30; the sliding cover 30 is slidably connected to the plate a12; the sanding belt 13 is detachably connected to the surface of the sliding cover 30, and the detachable connection method includes sticking and other methods, which is convenient for replacing the sanding belt 13; the fan 19 is arranged on the turntable 27 and connected to the expansion support assembly.

[0022] In this embodiment, a plurality of plates a12 are close to each other to form a cylindrical shape; the plate a12 is inserted into the inner side of the target hole until the bottom end of the plate a12 contacts the bottom end of the target hole (the length of the portion of the plate a12 inserted into the inner side of the target hole is at most the length of the slide cover 30), and under the action of the expansion component, the plates a12 at various locations are synchronously expanded to the surroundings uniformly, and when the slide cover 30 on one or more of the plates a12 contacts the inner wall of the target hole, under the action of the continuous expansion of the plate a12, a squeeze is generated between the slide cover 30 and the inner wall of the target hole. The force, under the action of the squeezing and pushing force (the action of force is mutual, which is equivalent to the inner wall of the target hole giving the slide cover 30 a squeezing and pushing force, and then giving the entire boring mechanism a squeezing and pushing force), causes the entire boring mechanism to shift toward the axial direction of the target hole until the slide covers 30 on all plates a12 are in contact with the inner wall of the target hole. At this time, the plate a12 stops moving, and the boring mechanism is adapted to the target hole (the axis of the boring mechanism coincides with the axis of the target hole; the axis of the boring mechanism is the axis of the cylinder formed by multiple plates a12 approaching each other).

[0023] In this embodiment, after the boring mechanism is matched with the target hole, the driving mechanism is used to drive the boring mechanism to rotate. At this time, the sliding cover 30 rotates accordingly, and the sanding belt 13 on its surface can grind the inner wall of the target hole, thereby realizing the cleaning function of burrs, chips and dirt on the inner wall of the target hole. At the same time, under the action of the fan 19, the wind force generated by the fan 19 can blow the dirt cleaned in the target hole into the shielding cover 8. Under the action of the magnetic part 11, the burrs and other dirt are magnetically attracted to the inner wall of the shielding cover 8, thereby realizing the automatic cleaning and recovery function of the dirt. After completing the cleaning operation, the telescopic part a21 is used to drive the sliding cover 30 to move upward, so that the sliding cover 30 moves out of the target hole.

[0024] Embodiment 2, as Figures 1-2As shown in the figure, an engine block boring equipment proposed by the present invention. Compared with the first embodiment, the structure of the clamping assembly is also introduced in detail in this embodiment. The clamping assembly includes a bidirectional lead screw a7, a motor a5, a nut block a, and a clamping plate 6. The bidirectional lead screw a7 is rotatably arranged inside the chute a. The motor a5 is arranged on the frame 1 and its output end is connected to the bidirectional lead screw a7. There are two nut blocks a which are slidably connected to the chute a. A through groove communicating with the chute a is opened inside the frame 1. The nut block a is threadedly connected to the bidirectional lead screw a7 and is connected with a U-shaped rod at the same time. The U-shaped rod passes through the through groove and is connected to the clamping plate 6. The clamping surface of the clamping plate 6 is provided with a rubber layer, and the surface of the rubber layer is provided with anti-slip lines for enhancing the friction between the clamping plate 6 and the cylinder block.

[0025] In this embodiment, the cylinder block to be bored is placed on the frame 1, and the motor a5 is turned on. The motor a5 drives the bidirectional lead screw a7 to rotate, so that the two nut blocks a move towards each other. The nut block a drives the U-shaped rod to move, and the U-shaped rod drives the two clamping plates 6 to move towards each other, realizing the clamping and fixing function of the cylinder block and ensuring the stability of the cylinder block during the boring operation.

[0026] Embodiment Three, as Figures 1-3 As shown in the figure, an engine block boring equipment proposed by the present invention. Compared with the second embodiment, the structure of the transverse movement assembly is also introduced in detail in this embodiment. The transverse movement assembly includes a motor b2, a transverse movement block 3, a telescopic component b4, and a transverse movement lead screw 9. The transverse movement block 3 is slidably connected to the chute b101. The transverse movement lead screw 9 is rotatably arranged in the chute b101. The motor b2 is arranged on the frame 1 and its output end is connected to the transverse movement lead screw 9. The telescopic component b4 is arranged on the transverse movement block 3 and its output end penetrates through the transverse movement block 3 and is connected to the sliding component. The telescopic component b4 includes but is not limited to devices such as cylinders.

[0027] In this embodiment, by turning on the motor b2, the motor b2 drives the transverse movement lead screw 9 to rotate, so that the transverse movement block 3 moves along the transverse movement lead screw 9. The transverse movement block 3 drives the telescopic component b4 to move, and the telescopic component b4 drives the sliding component to move. Then, the boring mechanism is driven by the sliding component to move, which is convenient for changing the position of the boring mechanism, enabling the boring mechanism to move to each target hole, and realizing the preliminary alignment function between the boring mechanism and each target hole (making the boring mechanism located above the target hole and ensuring that the plate a12 can be inserted into the inner side of the target hole).

[0028] Embodiment Four, as Figure 4 As shown in the figure, an engine block boring equipment proposed by the present invention. Compared with the third embodiment, the structure of the sliding component is also introduced in detail in this embodiment. The sliding component includes a groove cover 10, a guide rod 15, and a carrier block 17. The groove cover 10 is connected to the output end of the telescopic component b4. A chute c is opened on the inner wall of the groove cover 10. Both ends of the guide rod 15 are slidably connected to the chute c through sliders a. The carrier block 17 is slidably connected to the guide rod 15. The carrier block 17 is connected to the cover body 14.

[0029] In this embodiment, the guide rod 15 cooperates with the slider a to realize the lateral movement of the cover body 14, and the cover body 14 drives the boring mechanism to move horizontally; the carrier block 17 moves longitudinally on the guide rod 15, thereby driving the boring mechanism to move longitudinally. Under the combined effect of the above two movements, the function of free movement of the boring mechanism can be realized, which facilitates the rapid expansion of the plate a12 in the boring mechanism in the target hole, ensuring that the axis of the boring mechanism and the axis of the target hole quickly coincide.

[0030] Embodiment 5, as Figures 7-8 As shown, an engine cylinder boring device proposed by the present invention, compared with the fourth embodiment, this embodiment further introduces in detail the structure of the expansion component, the expansion component includes a bidirectional screw rod b29, a motor c25, a transmission rod 16 and a nut block b32; the bidirectional screw rod b29 is rotatably connected to the turntable 27; the bidirectional screw rod b29 is hollow and conductive at both ends, the bidirectional screw rod b29 is connected to the fan 19, and the wind force generated by the fan 19 can be blown into the inside of the target hole through the bidirectional screw rod b29. Since the target hole is not through, the wind force will rebound and then spray out from the target hole. In this process, the burrs and other dirt that have been polished off can be blown out; the nut block b32 is provided with two and connected with the bidirectional screw rod b29. The bidirectional screw rod b29 is threadedly connected (the bidirectional screw rod b29 is a high-precision screw rod); the nut block b32 is rotationally connected to one end of the transmission rod 16, and the other end of the transmission rod 16 is rotationally connected to the plate a12; the motor c25 is transmission-connected to the bidirectional screw rod b29; the bidirectional screw rod b29 is connected to a gear b20, and the output end of the motor c25 is connected to a gear a26 meshing with the gear b20; the nut block b32 is connected to an ultrasonic sensor 33 facing the plate a12 for measuring the moving distance of the plate a12; one end of the telescopic component a21 is connected to a slider b; the top end of the sliding cover 30 is connected to a slide plate 22; the slide plate 22 is slidably connected to the slider b.

[0031] In this embodiment, the motor c25 drives the gear a26 at its output end, the gear a26 drives the gear b20 to rotate, and the gear b20 drives the bidirectional screw rod b29 to rotate, so that the nut blocks b32 on both sides move toward each other, and the nut block b32 drives one end of the transmission rod 16 to move. Under the action of the rotational connection between the two, the angle between the transmission rod 16 and the nut block gradually increases, so that the other end of the transmission rod 16 pushes the plate a12 away from the bidirectional screw rod b29, thereby realizing the function of multiple plates a12 gathered in a cylindrical shape to disperse and expand from each other (the initial state of the multiple plates a12 is gathered in a cylindrical shape).

[0032] It should be noted that the ultrasonic sensor 33 can monitor the moving distance of the plate a12, and further monitor the moving distance of the boring tool 31, which is convenient for controlling the cutting amount during the boring operation; a controller and a control panel are provided on the frame 1, and the control panel is used to input the cutting amount; when the boring mechanism is adapted to the target hole and after the sliding cover 30 moves out of the target hole, the expansion and support assembly continues to work, so that the plate a12 drives the boring tool 31 to continue to move until the boring tool 31 contacts the inner wall of the target hole. At this time, the distance N between the plate a12 and the ultrasonic sensor 33 is recorded, and then the threshold value N+S is input using the control panel, where S is the cutting amount during boring. When the ultrasonic sensor 33 senses that the moving distance of the plate a12 reaches the threshold value, it feeds back to the controller, and the controller controls the motor c25 to stop working. At this time, the gear a26 no longer provides the driving force for the rotation of the gear b20, that is, the bi-directional lead screw b29 no longer has the driving force for its rotation, so the plate a12 will no longer drive the boring tool 31 to have a moving tendency, which is convenient for controlling the cutting amount of the boring tool 31.

[0033] Embodiment Six, as Figures 5-6 shown, an engine cylinder block boring device proposed by the present invention. Compared with Embodiment Five, the structure of the driving assembly is also introduced in detail in this embodiment. The driving assembly includes a toothed ring 18, a motor d23, and a gear c24. The toothed ring 18 is connected to the turntable 27, the motor d23 is connected to the cover 14, the output end of the motor d23 is connected to the gear c24, and the gear c24 meshes with the toothed ring 18.

[0034] In this embodiment, the motor d23 drives the gear c24 to rotate, the gear c24 drives the meshing toothed ring 18 to rotate, the toothed ring 18 drives the turntable 27 to rotate, and the turntable 27 drives the entire boring mechanism to rotate, providing the driving force for the cleaning of the target hole and the boring operation.

[0035] It should be noted that the engine cylinder block targeted in this patent is a cast iron cylinder block or other cylinder blocks that can be magnetically attracted.

[0036] In summary, when the present invention is used, first place the engine cylinder block to be bored on the frame 1, and then turn on the motor a5. The motor a5 drives the bi-directional lead screw a7 to rotate, so that the nut blocks a on both sides move towards each other. The nut blocks a drive the U-shaped rod to move, and the U-shaped rod drives the clamping plates 6 on both sides to move towards each other, realizing the clamping and fixing function of the cylinder block and ensuring the stability of the cylinder block during the boring operation.

[0037] After starting the motor b2, the motor b2 drives the transverse lead screw 9 to rotate, causing the transverse block 3 to drive the telescopic component b4, the sliding assembly, and the entire boring mechanism to move above the outermost boring hole on the cylinder block (starting from the outermost boring hole for boring operations and then proceeding with boring operations one by one in sequence), achieving the function of initially aligning the boring mechanism with the target hole (at this time, multiple plates a12 are in the initial state, and the initial state of multiple plates a12 is to gather together in a cylindrical shape); then control the telescopic component b4 to work, driving the sliding mechanism to move downward, and the sliding mechanism drives the boring mechanism to move downward until the bottom end of the plate a12 contacts the bottom end of the target hole (while the sliding mechanism realizes the connection function between the boring mechanism and the telescopic component b4 and ensures that the boring mechanism can move freely), causing the multiple plates a12 in the initial state to drive the sliding cover 30 to insert into the inner side of the target hole (during this process, the shielding cover 8 first contacts the surface of the cylinder block and covers the target hole, and a rubber layer is provided at the bottom end of the shielding cover 8, which can enhance the sealing performance of the shielding cover 8 for the target hole), and then start the motor c25. The motor c25 drives the gear a26 at its output end, and the gear a26 drives the meshing gear b20 to rotate. The gear b20 drives the bidirectional lead screw b29 to rotate, causing the nut blocks b32 on both sides to move towards each other. The nut block b32 drives one end of the transmission rod 16. Under the action of their rotational connection, the angle between the transmission rod 16 and the nut block gradually increases, causing the other end of the transmission rod 16 to push the plate a12 to move away from the bidirectional lead screw b29, realizing the function of the multiple plates a12 that are gathered in a cylindrical shape to disperse and expand. When the sliding cover 30 on one or more of the plates a12 contacts the inner wall of the target hole, under the continuous expansion of the plate a12, a squeezing force is generated between the sliding cover 30 and the inner wall of the target hole. Under the action of the squeezing force (the action of force is mutual, which is equivalent to the inner wall of the target hole giving the sliding cover 30 a squeezing force, and then giving the entire boring mechanism a squeezing force), the entire boring mechanism deflects towards the axis direction of the target hole until the sliding covers 30 on all the plates a12 contact the inner wall of the target hole. At this time, the plate a12 stops moving, realizing the function of quickly adapting the boring mechanism to the target hole (the axis of the boring mechanism coincides with the axis of the target hole; the axis of the boring mechanism is the axis of the cylinder formed by multiple plates a12 approaching each other), and at the same time, the motor c25 stops working.

[0038] After that, start the motor d23. The motor d23 drives the gear c24 at its output end. The gear c24 drives the toothed ring 18 to rotate. The toothed ring 18 drives the turntable 27 to rotate. The turntable 27 drives the entire boring mechanism to rotate, realizing the function of driving the sliding cover 30 to rotate by the plate a12. Thus, it can play a role in grinding and cleaning dirt such as burrs and chips on the inner wall of the target hole. At the same time, start the fan 19. The wind generated by the fan 19 is injected into the inner side of the bidirectional lead screw b29 from the top of the bidirectional lead screw b29, and then ejected from its bottom and enters the inner side of the target hole. Since the target hole is not through, the wind will rebound and be ejected from the target hole. During this process, the burrs and other dirt ground off can be blown out and enter the inner side of the shielding cover 8. The shielding cover 8 can prevent the dirt from spreading. At the same time, under the action of the magnetic part 11, the dirt can be magnetically attracted to the inner wall of the shielding cover 8, realizing the function of automatic cleaning and collection of the dirt.

[0039] After the cleaning operation is completed, use the telescopic part a21 to drive the sliding cover 30 to move upward, so that the sliding cover 30 moves out of the target hole. After that, control the motor c25 to start working again, so that the expansion and support assembly continues to drive the plate a12 to move until the boring tool 31 contacts the inner wall of the target hole. At this time, the plate a12 no longer moves. Keep the motor c25 working continuously, so that the plate a12 drives the boring tool 31 to have a tendency to move, that is, there is an extrusion force between the boring tool 31 and the target hole. Record the distance N between the plate a12 and the ultrasonic sensor 33 at this time. Then input the threshold value N + S through the control panel, where S is the cutting amount during boring. Then start the motor d23. The motor d23 drives the toothed ring 18 to rotate. The toothed ring 18 drives the turntable 27 to rotate. The turntable 27 drives the entire boring mechanism to rotate, so that the boring tool 31 rotates to realize the boring function of the inner wall of the target hole. When the ultrasonic sensor 33 senses that the moving distance of the plate a12 reaches the threshold value, it feeds back to the controller. The controller controls the motor c25 to stop working. At this time, the gear a26 no longer provides the driving force for the gear b20 to rotate, that is, the bidirectional lead screw b29 no longer has the driving force for its rotation. Then the plate a12 will no longer drive the boring tool 31 to have a tendency to move, which is convenient for controlling the cutting amount of the boring tool 31.

[0040] During the boring process, the blower 19 keeps working. The wind generated by the blower 19 can blow the debris generated during the boring process into the inside of the shielding cover 8. At the same time, under the action of the magnetic member 11, the debris is magnetically adsorbed on the inner wall of the shielding cover 8, realizing the automatic cleaning and recycling function of the debris. At the same time, under the action of the wind, it can play a role in cooling the target hole and the boring tool 31. After the above boring operation is completed, the controller controls the motor c25 to work, so that the expansion and support assembly drives the plate a12 to reset, and then drives the boring tool 31 to reset. Then, the telescopic member b4 is used to continue driving the boring mechanism to move up a certain distance (the distance that the boring mechanism moves up each time is controlled by the controller to control the telescopic member b4), so that the boring tool 31 performs boring operations on the remaining parts of the target hole. Until all the parts of the target hole that need to be bored are completed, the telescopic member b4 drives the entire boring mechanism to move out of the target hole. Then, the motor b2 is turned on again, so that the boring mechanism moves above the next target hole, and the above-mentioned cleaning operation and boring operation of the target hole are repeated. By analogy, the boring function of all the target holes on the cylinder block can be completed. This device can quickly realize the function of quickly adapting the boring mechanism to the target hole, without restricting the position of the boring mechanism to match a specific cylinder block, so that it can be adapted to cylinder blocks of various specifications, significantly increasing the flexibility of use and improving the boring efficiency.
