Description

Technical Field

[0001] The present invention relates to the technical field of hole processing of metal products, and specifically to a hole processing and grinding device for metal products. Background Art

[0002] The hole processing of metal products refers to opening holes on the surface of metal products through mechanical processing to meet specific design requirements or functional needs. This processing usually involves using equipment such as drill presses, punching presses, and numerically controlled machine tools, as well as corresponding cutting tools or punches. After the holes are opened on the metal products, the holes need to be polished.

[0003] When the existing hole grinding equipment is in operation, for some metal products with variable hole diameters, it is impossible to accurately perform mobile internal hole grinding according to the change of the hole diameter. Although for the grinding of some metal products installed on machine tools, a pre-programmed operation mode can be adopted for processing, there are often some small metal product processing factories, or when performing post-maintenance processing on metal products, there is often a lack of professional machine tool equipment. In such cases, generally, a grinding tool is manually operated for grinding, which has problems of slow speed, low efficiency, and insufficient grinding accuracy. Therefore, in view of the above problems, the present technical solution proposes a hole processing and grinding device for metal products. Summary of the Invention

[0004] The purpose of the present invention is to provide a hole processing and grinding device for metal products to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A hole processing and grinding device for metal products includes a manually controlled grinding mechanism. A plurality of groups of grinding tool heads are rotatably and radially movably installed at the output end of the manually controlled grinding mechanism. The manually controlled grinding mechanism automatically drives the grinding tool heads to rotate and semi-automatically adjusts the radial position of the grinding tool heads to adaptively and accurately grind the inner side of metal products with irregular structures. An axially moving base is detachably installed at the bottom of the manually controlled grinding mechanism to control the grinding tool heads to move towards the inside of the metal products. The fixation of the metal products is positioned by a corresponding fixing fixture (not shown in the figure), so as to realize adaptive moving grinding according to the change of the inner diameter of the metal products. The hand-controlled grinding mechanism includes a semi-automatic power box arranged on the side away from the grinding cutter head. On the side of the semi-automatic power box facing the grinding cutter head, a handheld barrel rod is installed. At the end of the handheld barrel rod, a circular fixed base plate is installed. The semi-automatic power box, the handheld barrel rod, and the fixed base plate are in a relatively static state. A rotating sleeve is rotatably sleeved outside the fixed base plate. The side of the end of the rotating sleeve away from the fixed base plate is detachably installed with multiple groups of grinding cutter heads. Inside the semi-automatic power box, a semi-automatic power mechanism is arranged. The output end of the semi-automatic power mechanism is connected with an adjustable transmission component. The output end of the adjustable transmission component extends into the rotating sleeve and is used to drive the rotating sleeve to rotate and control the radial movement of the grinding cutter head. The adjustable transmission component includes a rotating unit, a radial unit, and a power control unit. The rotating unit is connected with the semi-automatic power mechanism and is used to directly drive the rotating sleeve to control the grinding cutter head to rotate and grind. The radial unit is arranged inside and at the end of the rotating sleeve. The radial unit is selectively connected with the rotating unit through the power control unit. Thus, by means of the power transmission of the rotating unit, the radial unit is driven to operate to adjust the radial position of the grinding cutter head, so as to perform precise grinding according to the diameter change of the inner wall of the metal product.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a hand-controlled grinding mechanism, then detachably installing multiple groups of grinding cutter heads at the end of the hand-controlled grinding mechanism, and then using the automatic control of the hand-controlled grinding mechanism to rotate the grinding cutter head and the semi-automatic adjustment of the radial position of the grinding cutter head, and combining with the moving base that automatically moves axially at the bottom, the automatic and precise grinding treatment of metal products with multiple internal diameters is realized, improving the operation efficiency of the equipment for the repair or small amount of processing of some metal product holes; By arranging a handheld operating rod on the handheld barrel rod and detachably installing a support frame I, a support frame II, etc. at the bottom thereof, it is convenient to control the positioning operation or handheld flexible use of the equipment according to needs, and to a certain extent, improve the flexibility of the equipment and the convenience of operation.

[0025] As a preferred embodiment of the present invention, refer to Figure 1 , Figure 7 , the semi-automatic power mechanism includes a servo motor I 14 fixedly installed inside the semi-automatic power box 13 on the side away from the hand-held barrel rod 15. The output end of the servo motor I 14 is connected to an output shaft 18. The end of the output shaft 18 is connected to a rotating unit. The rotating unit includes a main rotating shaft 19 fixedly connected to the output shaft 18. The main rotating shaft 19 movably passes through the power control unit and the center of the hand-held barrel rod 15 and extends into the rotating sleeve 34, and at the same time passes through the partial radial unit and is fixedly connected to the inner wall of the rotating sleeve 34, so as to drive the rotating sleeve 34 to rotate around the fixed base plate 33; Specifically, refer to Figure 6, a rotating ring 35 is installed on the outer wall of the fixed base plate 33 in a circumferential manner. A circumferential rotating groove 36 is formed on the inner wall of the corresponding rotating sleeve 34 of the rotating ring 35. The rotating ring 35 is placed inside the rotating groove 36 for limited rotation, so as to maintain the rotating design of the rotating sleeve 34 relative to the fixed base plate 33; Refer to Figure 4 , Figure 5 , Figure 8 , the radial unit includes slide rails 28 radially distributed on the end of the rotating sleeve 34. A slide bar 27 is slidably connected to the inner side of the slide rail 28. A grinding tool base 26 is fixedly installed between the two slide bars 27. A plurality of grinding tool heads 11 are detachably installed on the outer side of the grinding tool base 26. On the inner side of the grinding tool base 26 near one end, a Z-shaped connecting rod 46 is installed. The end of the Z-shaped connecting rod 46 far from the grinding tool base 26 is connected with a nut I 44. A lead screw I 43 is threadedly connected to the nut I 44. One end of the lead screw I 43 is rotatably connected to the inner wall of the rotating sleeve 34 through a bearing 45, and the other end is installed with a worm gear 42. A group of worm shafts 41 are threadedly engaged on one side of the worm gear 42. The worm shaft 41 is sleeved outside the main rotating shaft 19 and is independent of the main rotating shaft 19 (this structure belongs to a toroidal worm drive. In this structure, the spiral teeth of the worm shaft 41 are distributed on the annular (circular arc rotary) surface, the teeth of the worm gear 42 are in direct envelope engagement, and the worm gear 42 can swing around the axis of the worm shaft 41 (that is, when the worm gear 42 is stationary, the worm shaft 41 has a certain swinging freedom along the axial direction of the worm gear 42)), and the worm shaft 41 movably passes through the fixed base plate 33 towards the inside of the hand-held barrel rod 15 and is connected with a radial adjustment main cylinder 20. That is, the main rotating shaft 19, the radial adjustment main cylinder 20, and the hand-held barrel rod 15 are in an interval distribution state of being wrapped in sequence. The ends of the main rotating shaft 19 and the radial adjustment main cylinder 20 are connected to the power control unit. At the same time, a guiding device for restricting its self-rotation is provided on the nut I 44. When controlling the radial adjustment main cylinder 20 to drive the worm shaft 41 to rotate, the worm gear 42 is synchronously driven to rotate. At this time, control the lead screw I 43 to rotate, so as to control the nut I 44 to move along the axial direction of the lead screw I 43. Then, under the connection of the Z-shaped connecting rod 46, control the grinding tool base 26 to move radially inside the support plate 48, and then perform radial adjustment on the grinding tool heads 11 installed on the outer side of the grinding tool base 26; Specifically, the end of the main rotating shaft 19 is connected to the inner side of the slide rail 28 through a connecting plate 25. When the main rotating shaft 19 rotates, control the connecting plate 25 to drive the whole rotating sleeve 34 to rotate. At this time, the worm gear 42 swings axially relative to the worm shaft 41, thereby realizing the synchronous rotation and radial adjustment of the grinding tool heads 11, and maintaining the precise and rapid inner wall grinding of the irregular metal product 10; Specifically, the slide bar 27 and the slide rail 28 are set as T-shaped structures to maintain the stable radial movement between the two.

[0026] Refer to Figure 1 ,Figure 3 , Figure 7 , the power control unit includes a fixed side gear 21 fixedly connected to the end of the radially adjustable main cylinder 20 on the side facing the output shaft 18. A limiting collar 53 is slidably sleeved on the main rotating shaft 19 on one side of the fixed side gear 21. On the side of the limiting collar 53 facing the fixed side gear 21, there is a ring of moving side gears 22 meshing with the fixed side gear 21. The inner side wall of the limiting collar 53 is provided with a positioning chute parallel to the axis. A positioning key is installed on the outer wall of the main rotating shaft 19 corresponding to the positioning chute. The positioning key is axially slidably connected to the positioning chute. That is, when the main rotating shaft 19 rotates, it drives the limiting collar 53 to rotate synchronously. At the same time, a collar 23 is movably sleeved in the middle of the limiting collar 53. One side of the collar 23 is connected with a connecting rod 24. By pushing the connecting rod 24, the collar 23 is controlled to drive the limiting collar 53 to move axially. Then, the moving side gear 22 and the fixed side gear 21 are controlled to mesh or disengage, so as to transfer the kinetic energy in the main rotating shaft 19 to the radially adjustable main cylinder 20. The end of the connecting rod 24 away from the collar 23 is vertically connected with a connecting block 40. The end of the connecting block 40 is rotatably connected with an adjusting screw 38. An internal thread hole 39 is opened in the box wall of the semi-automatic power box 13 corresponding to the adjusting screw 38. The adjusting screw 38 passes along the internal thread in the internal thread hole 39. The outer end of the adjusting screw 38 is connected with a turning handle 37 arranged outside the semi-automatic power box 13. By rotating the turning handle 37, the adjusting screw 38 is driven to rotate in the internal thread hole 39, so as to control the axial position of the adjusting screw 38. Then, under the connection of the connecting block 40 and the connecting rod 24, the collar 23 is controlled to drive the limiting collar 53 to move axially, realizing whether the kinetic energy in the main rotating shaft 19 is transferred to the radially adjustable main cylinder 20, that is, realizing semi-automatic radial control adjustment.

[0028] As a preferred embodiment of the present invention, referring to Figure 5 , a mounting plate 29 is installed on the outer side wall of the grinding tool base 26. Two grinding tool mounting substrates 30 are symmetrically installed on both sides of the mounting plate 29 along the moving direction. Threaded holes and embedded holes are respectively opened on the sides of the two grinding tool mounting substrates 30 away from each other. At the same time, threaded rods and embedded rods are installed at the ends of the grinding rods at the bottom of the grinding tool head 11. The threaded rods and the embedded rods are respectively connected to the threaded holes and the embedded holes on the grinding tool mounting substrates 30, so as to facilitate quickly replacing a suitable grinding tool head 11 according to the grinding requirements for effective grinding.

[0029] The working principle of the present invention is as follows: At the idle position of the device, all the above-mentioned driving components, which refer to power components, electrical components, and the adapted power supply, are connected by wires, and the electrical connection is completed in the order of the working sequence of each electrical component.

During operation, the metal product 10 is fixed by a fixing fixture, and then according to the grinding requirements, support frame I 31 and support frame II 32 are installed at the bottom of the semi-automatic power box 13 and the fixed base plate 33. Then, it is connected to the nut II 56 inside the moving base 54 through the support plate 48. Then, by starting the operation of the servo motor II 55, the nut II 56 is controlled to move along the servo motor II 55, so as to accurately and automatically control the axial movement of the semi-automatic power box 13, the fixed base plate 33, and the rotating sleeve 34. At the same time, before that, by starting the operation of the servo motor I 14, the output shaft 18 is directly driven to control the rotation of the main rotating shaft 19. At the same time, the required grinding cutter head 11 is installed on the grinding cutter mounting substrate 30. Then, according to the grinding depth and position requirements, the moving side gear 22 is driven to mesh with the fixed side gear 21 by rotating the handle 37, and then the radial adjustment main cylinder 20 is controlled to rotate, so as to drive the worm 41 to control the rotation of the worm gear 42, and then drive the nut I 44 to move along the lead screw I 43, and further control the grinding cutter base 26 to move along the slide rail 28 to adjust the radial position of the grinding cutter head 11, thereby realizing the operation mode of accurately and automatically adapting to grind the inside of the metal product 10; Secondly, it is also possible to directly control the movement of the handheld barrel rod 15 by holding the handheld operating rod 16 without installing the support frame I 31 and the support frame II 32. Then, the servo motor I 14 drives the rotating sleeve 34 to rotate to drive the grinding cutter head 11 to rotate, and according to the need, the radial extension position of the end of the grinding cutter head 11 is adjusted to perform targeted grinding on different position depths inside the metal product 10, further expanding the flexibility and application range of the grinding equipment.
