Description

Technical Field

[0001] This application relates to the field of polishing technology, and more particularly to a polishing device. Background Technology

[0002] When polishing the threaded groove structure on workpieces such as lead screws, two power devices are usually required. One power device is used to drive the polishing head to move back and forth along the axis of the lead screw, and the other power device is used to drive the polishing head to rotate around the lead screw, which results in a high cost for the entire polishing device. Utility Model Content

[0003] This application provides polishing equipment to address the problem of high cost of polishing devices in the known art.

[0004] This application provides a polishing device for polishing the outer peripheral surface of a rotating workpiece, wherein the outer peripheral surface of the rotating workpiece is provided with a first thread; the polishing device includes a clamping assembly, a rotating assembly, and a polishing element; the clamping assembly is configured to clamp the rotating workpiece; the rotating assembly is configured to drive the rotating workpiece clamped by the clamping assembly to rotate; the polishing element is sleeved on the outer peripheral surface of the rotating workpiece, and the inner wall of the polishing element is provided with a second thread, the second thread engaging with the first thread, so as to polish the outer peripheral surface of the rotating workpiece through the polishing element, and based on the rotation of the rotating workpiece, the rotating workpiece can drive the polishing element to move along a first direction, the first direction being parallel to the direction of the axis of the rotating workpiece.

[0005] In one possible implementation, the polishing element includes a first polishing element and a second polishing element. Along a second direction, the first polishing element and the second polishing element are spaced apart, and a receiving cavity is formed between the first polishing element and the second polishing element. The polishing element is partially located within the receiving cavity, and the second direction intersects with the first direction.

[0006] Along the second direction, the first polished part and the second polished part are provided with the second thread on their adjacent sides.

[0007] In one possible implementation, the polishing equipment further includes a first clamping assembly, which includes a clamping drive member. The clamping drive member is tractively connected to the first polishing piece and the second polishing piece, and is used to drive the first polishing piece and the second polishing piece to abut against the outer peripheral surface of the rotating workpiece.

[0008] In one possible implementation, the polishing apparatus further includes a positioning component comprising a first positioning element and a second positioning element, wherein the first positioning element and the second positioning element are spaced apart along the first direction, the first positioning element being configured to detect that the polished part has moved to a first position, and the second positioning element being configured to detect that the polished part has moved to a second position.

[0009] In one possible implementation, the positioning component further includes a controller, which is signal-connected to the first positioning element and is used to receive a first position signal detected by the first positioning element; the controller is also signal-connected to the second positioning element and is used to receive a second position signal detected by the second positioning element.

[0010] The controller signal is connected to the rotary assembly. Based on the first position signal and the second position signal, the controller controls the rotary assembly to provide a reverse driving force so that the rotary workpiece switches its rotation direction.

[0011] In one possible implementation, the clamping assembly includes a first clamping member and a second clamping member, which are spaced apart along the first direction.

[0014] In one possible implementation, the second clamping member is movable relative to the mounting member along the first direction, and the polishing apparatus further includes a clamping assembly configured to abut against the second clamping member so that the second clamping member abuts the rotating workpiece against the first clamping member.

[0015] In one possible implementation, the polishing apparatus further includes a guide, to which the mounting member is slidably connected along the first direction.

[0016] In one possible implementation, the polishing apparatus further includes a liquid circulation assembly configured to spray polishing media onto the rotating workpiece, and the liquid circulation assembly is also configured to recover the polishing media after it has been applied to the rotating workpiece.

[0017] The polishing equipment of this application, by fitting a polishing piece onto the outer peripheral surface of a rotating workpiece, allows relative movement between the workpiece and the polishing piece when the rotating assembly drives the workpiece to rotate, thus enabling the polishing piece to polish the outer peripheral surface of the workpiece. Furthermore, a second thread is provided on the inner wall of the polishing piece, which engages with a first thread on the outer peripheral surface of the workpiece. When the workpiece rotates, it drives the polishing piece to move along the axis of the workpiece, allowing the polishing piece to polish the outer peripheral surface of various areas of the workpiece along its axis. Both the rotational and sliding movements of the polishing piece relative to the workpiece are powered by the rotating assembly, thereby reducing the cost of the polishing equipment.

[0032] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 4 As shown, this embodiment provides a polishing device 100 for polishing the outer peripheral surface of a rotating workpiece 1. The outer peripheral surface of the rotating workpiece 1 is provided with a first thread 101. The polishing device 100 can polish the thread groove structure on the outer peripheral surface of the rotating workpiece 1 used to form the first thread 101, thereby improving the transmission accuracy of the rotating workpiece 1. The rotating workpiece 1 can be a workpiece with a thread groove structure, such as a lead screw.

[0034] For ease of reading, this application introduces the terms first direction Z, second direction X, and third direction Y to describe the embodiments of this application. The first direction Z, second direction X, and third direction Y can be three non-parallel straight lines in space; further, the first direction Z, second direction X, and third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Y as the Y-axis direction of the three-dimensional coordinate system.

[0035] The polishing equipment 100 includes a clamping assembly 40, a rotating assembly 50, and a polishing piece 2. The clamping assembly 40 is configured to clamp a rotating workpiece 1, which is positioned along a first direction Z when clamped on the clamping assembly 40. The rotating assembly 50 is configured to drive the rotating workpiece 1 clamped by the clamping assembly 40 to rotate about its own axis. The polishing piece 2 is sleeved on the outer peripheral surface of the rotating workpiece 1, and the inner wall of the polishing piece 2 is provided with a second thread 203, which engages with a first thread 101 to polish the outer peripheral surface of the rotating workpiece 1. Based on the rotation of the rotating workpiece 1, the rotating workpiece 1 can drive the polishing piece 2 to move along the first direction Z, which is parallel to the direction of the axis of the rotating workpiece 1.

[0036] Thus, the polishing equipment 100 of this application, by sleeved on the outer peripheral surface of the rotating workpiece 1, allows relative movement between the rotating workpiece 1 and the polishing part 2 when the rotating assembly 50 drives the rotating workpiece 1 to rotate, thereby enabling the polishing part 2 to polish the outer peripheral surface of the rotating workpiece 1. Furthermore, the inner wall of the polishing part 2 is provided with a second thread 203, which engages with the first thread 101 on the outer peripheral surface of the rotating workpiece 1. When the rotating workpiece 1 rotates, it drives the polishing part 2 to move along the axis of the rotating workpiece 1, thereby enabling the polishing part 2 to polish the outer peripheral surface of various regions of the rotating workpiece 1 along its axis. The rotational movement and sliding movement of the polishing part 2 relative to the rotating workpiece 1 are both powered by the rotating assembly 50, thereby reducing the cost of the polishing equipment 100.

[0037] Please combine Figures 1 to 3 In one embodiment, the polishing equipment 100 further includes a moving component 10, a processing table 12, and a housing 11. The moving component 10 is a vehicle such as a trolley or trailer, and the processing table 12 is mounted on the moving component 10 so that the moving component 10 can drive the processing table 12 to move.

[0038] A guide member 13 is provided on the processing table 12. The outer shell 11 is fixed on the processing table 12, and both the guide member 13 and the rotating workpiece 1 are located inside the outer shell 11 to facilitate polishing operations within the outer shell 11. The guide member 13 is generally cylindrical and is arranged along the first direction Z. The bottom end of the guide member 13 is connected to the top surface of the processing table 12, and the top end of the guide member 13 is provided with a top plate 14.

[0039] In this embodiment, along the third direction Y, the clamping assembly 40 is spaced apart on one side of the guide member 13. The clamping assembly 40 includes a first clamping member 41 and a second clamping member 42. Along the first direction Z, the first clamping member 41 and the second clamping member 42 are spaced apart, the first clamping member 41 abuts against one end of the rotating workpiece 1, and the second clamping member 42 abuts against the other end of the rotating workpiece 1.

[0040] At least one end of the first clamping member 41 and the second clamping member 42 adopts a conical structure, and the tips of the conical structures of the first clamping member 41 and the second clamping member 42 abut against the opposite ends of the rotating workpiece 1, thereby improving the stability of the clamping of the rotating workpiece 1.

[0041] Please combine Figure 5 And see Figure 2 In one embodiment, the rotary assembly 50 is drive-connected to the first clamping member 41 and is used to drive the first clamping member 41 to rotate.

[0042] The rotary assembly 50 includes a rotary drive 51, a rotary mounting base 52, and a rotary table 53. The rotary drive 51 is a drive device such as a motor, and is installed inside a cavity 120 formed within the machining table 12. The rotary mounting base 52 is fixed to the top surface of the machining table 12. The machining table 12 has a first through hole 122, and both the rotary mounting base 52 and the rotary table 53 have second through holes 530. The two second through holes 530 are connected. The first through hole 122 connects the cavity 120 of the machining table 12 and the second through hole 530, so that the driving end of the rotary drive 51 can pass through the first through hole 122 and the second through hole 530 and connect to the rotary table 53. A first clamping member 41 is installed on the rotary table 53 so that the rotary drive 51 drives the first clamping member 41 to rotate.

[0043] In this embodiment, the polishing equipment 100 further includes a second clamping assembly 30, which is fixed on the rotary table 53 and is used to clamp the outer peripheral surface of the rotating workpiece 1 near the end of the first clamping member 41.

[0044] Specifically, the second clamping assembly 30 includes a first connecting seat 31, a second connecting seat 32, a first clamping member 33, and a second clamping member 34. Along the second direction X, the first connecting seat 31 and the second connecting seat 32 are spaced apart, and both are fixed to the top surface of the rotary table 53. The first clamping member 33 and the second clamping member 34 are both arranged along the second direction X. Along the second direction X, one end of the first clamping member 33 is connected to the first connecting seat 31, and the other end abuts against the outer wall of one side of the rotating workpiece 1. Along the second direction X, one end of the second clamping member 34 is connected to the second connecting seat 32, and the other end abuts against the outer wall of the other side of the rotating workpiece 1, so as to clamp the rotating workpiece 1 by means of the first clamping member 33 and the second clamping member 34.

[0045] Specifically, along the second direction X, both the first clamping member 33 and the second clamping member 34 are provided with limiting grooves 35. The shape of the limiting grooves 35 is adapted to the shape of the rotating workpiece 1 so that part of the rotating workpiece 1 is located in the limiting grooves 35, thereby further improving the stability of the clamping position of the rotating workpiece 1.

[0046] Furthermore, the first clamping member 33 has a first locking hole 330, and the second clamping member 34 has a second locking hole 340. Both the first locking hole 330 and the second locking hole 340 are threaded holes, allowing a threaded component such as a double-ended bolt to pass through them. This allows the first clamping member 33 and the second clamping member 34 to be fixed together by the double-ended bolt after they are brought close together, preventing the first clamping member 33 and the second clamping member 34 from shifting positions.

[0047] Please combine Figure 6 and Figure 7 In one embodiment, the clamping assembly 40 further includes a mounting member 81, which is disposed along a third direction Y, and one end of the mounting member 81 is sleeved on the outer peripheral surface of the guide member 13, thereby slidably connecting the mounting member 81 to the guide member 13. A second clamping member 42 is connected to the mounting member 81, so that the distance between the second clamping member 42 and the first clamping member 41 can be adjusted by sliding the mounting member 81 relative to the guide member 13, thereby adapting to rotating workpieces 1 of different lengths.

[0048] Along the third direction Y, the end of the mounting member 81 near the guide member 13 has two locking protrusions 812. Along the second direction X, the two locking protrusions 812 are spaced apart, and a sliding hole is formed between the two locking protrusions 812. The sliding hole allows the guide member 13 to pass through, so as to realize the sliding of the mounting member 81 relative to the guide member 13. Each of the two locking protrusions 812 has a third locking hole 8120. Both third locking holes 8120 are threaded holes, so that a threaded object such as a double-ended bolt can pass through the two third locking holes 8120, thereby locking the two locking protrusions 812. Thus, after the mounting member 81 slides to the preset position, the mounting member 81 and the guide member 13 are fixed relative to each other.

[0049] In this embodiment, the second clamping member 42 is rotatably connected to the end of the mounting member 81 away from the locking protrusion 812, and the second clamping member 42 can rotate with the rotating workpiece 1. The polishing equipment 100 also includes a clamping assembly 80, which is configured to abut against the second clamping member 42 so that the second clamping member 42 presses the rotating workpiece 1 against the first clamping member 41.

[0050] Specifically, the clamping assembly 80 includes a first sleeve 84, a second sleeve 83, an elastic element 86, a supporting element 85, and a rotating element 82.

[0051] The mounting member 81 has a third through hole 810 at the end away from the locking protrusion 812, and the third through hole 810 passes through the mounting member 81 along the first direction Z. The first sleeve 84 passes through the third through hole 810, and the two ends of the first sleeve 84 are located outside the third through hole 810 and are located on the upper and lower sides of the mounting member 81, respectively.

[0052] The second clamping member 42 is inserted through the first sleeve 84, and both ends of the second clamping member 42 are located outside the first sleeve 84. The second clamping member 42 can rotate inside the first sleeve 84 so that the second clamping member 42 can rotate with the rotating workpiece 1.

[0053] The second sleeve 83 is connected to the bottom end face of the mounting member 81, and the second sleeve 83 is sleeved on the outer periphery of the first sleeve 84. The inner peripheral surface of the second sleeve 83 is spaced apart from the outer peripheral surface of the first sleeve 84, and the elastic member 86 is located between the second sleeve 83 and the first sleeve 84, and is sleeved on the outer peripheral surface of the first sleeve 84.

[0054] One end of the elastic element 86 elastically abuts against the second sleeve 83, and the other end elastically abuts against the mounting member 81. The elastic element 86 is a compression spring, so that it always provides a downward elastic force to the second sleeve 83. Along the first direction Z, the stepped portion provided on the second sleeve 83 can abut against the second clamping member 42. When the elastic element 86 abuts against the second sleeve 83 downward, the second sleeve 83 further abuts against the second clamping member 42 downward, thereby ensuring that the second clamping member 42 presses the rotating workpiece 1 against the first clamping member 41.

[0055] The top surface of the mounting component 81 is provided with a rotating seat 811. The rotating component 82 is approximately "V" shaped, and the corner of the rotating component 82 is rotatably connected to the rotating seat 811 via a pivot, so that the rotating component 82 can rotate relative to the rotating seat 811. The abutment 85 is located above the mounting component 81 and is sleeved on the outer circumferential surface of the first sleeve 84. The abutment 85 and the mounting component 81 are spaced apart, and one end of the rotating component 82 is located in the space between the abutment 85 and the mounting component 81, so that when the rotating component 82 rotates, it can push the abutment 85 to move upward, thereby driving the first sleeve 84 and the second clamping component 42 rotatably installed in the first sleeve 84 to move upward.

[0056] Thus, when it is necessary to disassemble or assemble the rotating workpiece 1, the rotating component 82 is turned to lift the second clamping component 42 upward, thereby moving the second clamping component 42 away from the first clamping component 41 to facilitate the handling of the rotating workpiece 1. After the bottom end of the rotating workpiece 1 is installed, the rotating component 82 is released, and the elastic component 86, under its own reset action, pushes the second clamping component 42 downward, thereby clamping the rotating workpiece 1 between the second clamping component 42 and the first clamping component 41.

[0057] Please combine Figure 7 And see Figure 2 In one embodiment, the polishing apparatus 100 further includes a balancing assembly 60. The balancing assembly 60 includes a balancing element 61, a guide wheel 63, and a wire rope 62.

[0058] Two guide wheels 63 are provided, and both guide wheels 63 are fixed to the bottom surface of the top plate 14. The wire rope 62 is arranged in a roughly "U" shape, with the two guide wheels 63 wound around its middle section in sequence. One end of the wire rope 62 is connected to the mounting component 81, and the other end of the wire rope 62 is connected to the balancing component 61. The balancing component 61 is a relatively heavy element such as a steel block.

[0059] When it is necessary to adjust the position of the mounting part 81 relative to the guide part 13, the threaded parts on the two locking protrusions 812 are removed. The balance part 61 can provide an upward pulling force to the mounting part 81 through the wire rope 62 to balance the weight of the mounting part 81, thereby saving effort.

[0060] Please combine Figure 8 And see Figure 4 In one embodiment, the polishing element 2 includes a first polishing element 2 and a second polishing element 2. Along the second direction X, the first polishing element 2 and the second polishing element 2 are spaced apart, and a receiving cavity 204 is formed between the first polishing element 2 and the second polishing element 2, with a portion of the polishing element 2 located within the receiving cavity 204.

[0061] Both the first polishing part 2 and the second polishing part 2 are semi-circular ring structures, and the shapes of the first polishing part 2 and the second polishing part 2 are adapted to the shape of the rotating workpiece 1 so that the first polishing part 2 and the second polishing part 2 can fit more closely to the outer circumferential surface of the rotating workpiece 1.

[0062] Along the second direction X, the first polishing part 2 and the second polishing part 2 are provided with a second thread 203 on their adjacent sides, so that the first polishing part 2 and the second polishing part 2 can move back and forth along the first direction Z under the rotation of the rotating workpiece 1.

[0063] In this embodiment, the polishing equipment 100 further includes a first clamping assembly 90, which includes a clamping drive 94. The clamping drive 94 is connected to the first polishing piece 2 and the second polishing piece 2 and is used to drive the first polishing piece 2 and the second polishing piece 2 to abut against the outer peripheral surface of the rotating workpiece 1.

[0064] Specifically, the first clamping assembly 90 further includes a clamping seat 91, a first moving member 92, and a second moving member 93. Along the third direction Y, the guide member 13 has a guide groove 130 on the side near the rotating workpiece 1, and the guide groove 130 is arranged along the first direction Z. Along the third direction Y, the clamping seat 91 is located on the side of the guide member 13 near the rotating workpiece 1, and a guide protrusion 910 protrudes from the side of the clamping seat 91 near the guide member 13. The guide protrusion 910 is slidably disposed within the guide groove 130 to guide the clamping seat 91 to slide along the first direction Z via the guide member 13.

[0065] Along the second direction X, the first moving member 92 and the second moving member 93 are spaced apart, and both the first moving member 92 and the second moving member 93 can slide relative to the clamping seat 91 along the second direction X. The clamping drive member 94 is a screw, and both the first moving member 92 and the second moving member 93 have threaded holes. The clamping drive member 94 passes through the two threaded holes, and the clamping drive member 94 is specifically a two-stage screw, so that the first moving member 92 and the second moving member 93 can be moved closer to each other or further away from each other by rotating the clamping drive member 94.

[0066] Furthermore, the first clamping assembly 90 also includes a first clamping plate 95, a second clamping plate 96, and a buffer member 97. The first clamping plate 95 and the second clamping plate 96 are located between the first moving member 92 and the second moving member 93. Along the second direction X, the first clamping plate 95 is slidably connected to the side of the first moving member 92 near the second moving member 93, and the second clamping plate 96 is slidably connected to the side of the second moving member 93 near the first moving member 92. The first polishing member 2 is connected to the side of the first clamping plate 95 near the second clamping plate 96, and the second polishing member 2 is connected to the side of the second clamping plate 96 near the first clamping plate 95. Thus, by rotating the clamping drive member 94, the first moving member 92 and the second moving member 93 can be moved closer to or further away from each other, thereby enabling the first polishing member 2 and the second polishing member 2 to move closer to or further away from each other.

[0067] Specifically, the first clamping plate 95 is connected to the first moving member 92 by a buffer member 97, and the second clamping plate 96 is connected to the second moving member 93 by a buffer member 97. The buffer member 97 is a spring, thereby providing buffering force between the first clamping plate 95 and the first moving member 92, and between the second clamping plate 96 and the second moving member 93, to prevent the first polishing member 2 and the second polishing member 2 from clamping the rotating workpiece 1 too tightly and damaging the thread groove structure.

[0068] Please combine Figure 9 And see Figure 5 and Figure 6 In one embodiment, the polishing apparatus 100 further includes a positioning component 70, which includes a first positioning element 71 and a second positioning element 72. The first positioning element 71 and the second positioning element 72 are spaced apart along a first direction Z. The first positioning element 71 is configured to detect that the polished part 2 has moved to a first position, and the second positioning element 72 is configured to detect that the polished part 2 has moved to a second position.

[0069] Both the first positioning element 71 and the second positioning element 72 are photoelectric sensors or laser sensors, and both are fixed to the guide element 13. The first positioning element 71 and the second positioning element 72 can detect whether the clamping seat 91 has moved to the first position and the second position, and then detect whether the polishing part 2 installed on the clamping seat 91 has moved to the first position and the second position.

[0070] Furthermore, the positioning component 70 also includes a controller 73, which is signal-connected to the first positioning element 71 and is used to receive a first position signal detected by the first positioning element 71. The controller 73 is signal-connected to the second positioning element 72 and is used to receive a second position signal detected by the second positioning element 72. The controller 73 is signal-connected to the rotation drive element 51 of the rotation component 50, which is a drive device such as a motor. Based on the first and second position signals, the controller 73 controls the rotation drive element 51 to provide a reverse driving force, so that the rotating workpiece 1 switches its rotation direction. Then, when the polishing part 2 moves to the first or second position, the controller 73 controls the rotation drive element 51 to reverse, so that the polishing part 2, which has moved to one of the first and second positions, begins to move towards the other, thereby realizing that the polishing part 2 automatically and repeatedly polishes the rotating workpiece 1.

[0071] Please combine Figure 6 And see Figure 1 and Figure 2 In one embodiment, the polishing equipment 100 further includes a liquid circulation component 20, which is configured to spray polishing medium onto the rotating workpiece 1. The polishing medium may be polishing oil or the like. The liquid circulation component 20 is also configured to recover the polishing medium after it has acted on the rotating workpiece 1.

[0072] Specifically, the hydraulic circulation assembly 20 includes an oil reservoir 21, a delivery pump, an oil nozzle 24, and a recovery pipe 23. The oil reservoir 21 is placed on the moving assembly 10, and the oil nozzle 24 is connected to the mounting component 81, with the oil nozzle 24 facing the rotating workpiece 1. The delivery pump is connected to the oil nozzle 24 through a pipe to deliver the polishing medium stored in the oil reservoir 21 to the oil nozzle 24, which then sprays the polishing medium onto the outer peripheral surface of the rotating workpiece 1. A recovery port 121 is provided on the top surface of the processing table 12. One end of the recovery pipe 23 is connected to the recovery port 121, and the other end can extend into the oil reservoir 21, so that the polishing medium falling from the rotating workpiece 1 can enter the recovery pipe 23 through the recovery port 121 and then be recovered back into the oil reservoir 21 through the recovery pipe 23.

[0073] Specifically, the oil storage tank 21 is equipped with a filter screen 22. The polishing medium flowing out of the recovery pipe 23 is first filtered by the filter screen 22 before being transported to the oil storage tank 21 for storage.

However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
