Description

Technical Field

[0001] The present invention relates to the technical field of polishing equipment, and particularly to a polishing machine for the outer wall of a lamp cup. Background Art

[0002] The lamp cup product is a special-shaped reflective bowl similar to an ellipse and is applied in an ultraviolet exposure machine. When the lamp cup is manufactured: the inner surface and the outer surface of the initial blank of the lamp cup after hot bending and forming are uneven, and it is necessary to polish its inner and outer surfaces, and the polishing accuracy requirement is high. Due to the special shape of the initial blank of the lamp cup, which is not a standard ellipse, it is difficult to polish the lamp cup. There are a port and a central hole on the lamp cup, the size of the port is much larger than that of the central hole, and the port and the central hole are located at both ends of the lamp cup, as Figure 1 shown.

[0003] An ellipsoidal lamp cup processing device disclosed in the patent publication number CN207326637U, and a lamp cup shaping and polishing process and device disclosed in the patent publication number CN117020911B. The above patents have all disclosed the polishing solutions for the inner wall of the lamp cup. On this basis, it is also necessary to polish the outer wall of the lamp cup. Most of the existing polishing equipment has problems such as low surface accuracy, poor finish, low processing efficiency, high cost, low automation level, and weak versatility.

[0004] For the outer wall polishing of a curved workpiece, a cast iron pan outer wall grinding device disclosed in the patent publication number CN206484369U can grind the outer wall of the cast iron pan by a grinding head on the basis of the rotation of the cast iron pan. The area of the grinding head is small and it cannot fully contact the outer wall of the cast iron pan. However, the grinding head can slide and be fixed on the curved rod adjusting part, and then grind the cast iron pan section by section. It can be seen that it uses manual adjustment means to control the grinding angle and position. The grinding operation is cumbersome and the processing efficiency is low. Moreover, it is difficult to ensure the consistency of each section of grinding and polishing of the cast iron pan, the polishing uniformity is low, and the polishing quality is difficult to guarantee.

[0005] A numerically controlled routing machine for producing high-temperature resistant and non-deformable bamboo bowls disclosed in the patent publication number CN207359289U drives a polishing mechanism to rotate by a driving motor, thereby polishing the bamboo bowl. The polishing mechanism is composed of two polishing pieces with adjustable spacing and can automatically polish the outer wall of the bamboo bowl comprehensively. However, the polishing pieces need to be evenly attached to the outer contour of the bamboo bowl to achieve uniform polishing. It is inconvenient to adjust the pressure of the polishing pieces on the bamboo bowl, and thus it is difficult to flexibly control the friction force between the two, and the polishing efficiency is uncontrollable. For the polishing operation of bamboo bowls with different sizes and shapes, it is necessary to separately adjust and replace the polishing pieces, and thus additional cumbersome operations are required. Summary of the Invention

[0006] In order to solve the problems that when a conventional polishing device is applied to polish the outer wall of a curved workpiece, the polishing uniformity is low and it is difficult to conveniently adapt to curved workpieces of different sizes and radian, the present invention provides a polishing machine for the outer wall of a lamp cup. The X and Y bidirectional displacement modules can drive the polishing mechanism to move freely, so that lamp cups of different sizes and radian can be polished, and the application range is wide. On the premise that the lamp cup workpiece rotates freely at a fixed position, the polishing mechanism reciprocates up and down along the outer wall of the lamp cup, which can ensure the comprehensiveness and uniformity of polishing and improve the polishing accuracy.

The upper end of the polishing track is hinged to the movable plate, and the lower end is connected to one side of the installation frame through a pressure cylinder; the pressure cylinder is convenient for controlling the swing of the polishing track, and the swing is to approach or move away from the lamp cup;

[0011] A plurality of the polishing units reciprocally slide on the polishing track, and the swing motor provides sliding power for the polishing units. The plurality of polishing units are connected together through a connecting plate, which is convenient for the linkage control between the polishing units. Each polishing unit is provided with a rotatable polishing wheel. The plurality of polishing wheels are attached to the outer wall of the lamp cup and reciprocate up and down along the height direction of the lamp cup, which is convenient for comprehensively and uniformly polishing the lamp cup.

[0012] Further, the rotary clamping mechanism includes a fixed cylinder, a column rotatably arranged in the fixed cylinder and a driving motor for driving the column to rotate. A clamping member for fixing the lamp cup is arranged on the column.

[0013] Further, the column vertically penetrates the fixed cylinder, and the column and the fixed cylinder are rotatably connected through a bearing, which improves the smoothness of the rotation of the column;

[0014] The lower end of the column extends out of the fixed cylinder and is driven by a belt by the driving motor. The upper end of the column extends out of the fixed cylinder and extends above the polishing platform. The column located above the polishing platform is of a threaded rod structure.

[0015] Furthermore, a clamping member is detachably arranged at the upper end of the column, and the column is detachably connected to the lamp cup through the clamping member.

[0016] Furthermore, the clamping member includes a lower positioning sleeve, a positioning disc and an upper positioning sleeve. The cross-section of the lower positioning sleeve is convex-shaped, and the cross-section of the upper positioning sleeve is inverted convex-shaped. The upper positioning sleeve and the lower positioning sleeve are arranged at intervals up and down on the column and are threadedly connected to the column, which is convenient for adjusting the positions of the upper and lower positioning sleeves;

[0017] The positioning disc is coaxially arranged on the lower positioning sleeve. The edge of the positioning disc is of a stepped structure, which is convenient for positioning the lamp cup. The lamp cup is inverted between the upper positioning sleeve and the positioning disc. The upper positioning sleeve is inserted into the central hole of the lamp cup, and the edge of the port of the lamp cup abuts against the edge of the positioning disc.

[0018] Furthermore, the mounting frame is a portal frame. The two-axis motion module includes a longitudinal lead screw module and a transverse lead screw module, which is convenient for providing bidirectional motion in the X-axis and Y-axis directions. The longitudinal lead screw module is vertically arranged at the top of the mounting frame. The longitudinal lead screw module is connected to the transverse lead screw module downward, which is convenient for driving the transverse lead screw module to move up and down. The transverse lead screw module is arranged between the two sides of the mounting frame. The transverse lead screw module moves up and down along the mounting frame. The transverse lead screw module is connected to the movable plate, and the movable plate is controlled by the transverse lead screw module and moves left and right along the mounting frame.

[0019] Furthermore, there is a gap between the polishing track and the outer wall of the lamp cup. A pressure cylinder is hinged to one side of the mounting frame, and the piston rod of the pressure cylinder is connected to the lower end of the polishing track;

[0020] A crank-slider mechanism is arranged between the output shaft of the swing motor and the connecting plate to connect them. The swing motor drives the polishing unit to reciprocate through the crank-slider mechanism. The connecting plate drives multiple polishing units to reciprocate along the polishing track together.

[0023] Furthermore, the other side of the sliding disc is detachably provided with a mounting plate, the polishing rod is arranged on the mounting plate, and the mounting plate is rotationally connected to the polishing wheel through the polishing rod.

[0024] Through the above technical solutions, the beneficial effects of the present invention are as follows:

[0025] The present invention has a reasonable structural design, and the rotary clamping mechanism can conveniently drive the lamp cup to rotate circumferentially. The driving motor drives the column to rotate through a belt drive mode. The column can rotate smoothly in the fixed cylinder. There is a clamping member at the top of the column, which can firmly and stably clamp the lamp cup to fix it and drive the lamp cup to rotate stably. The distance between the positioning disk and the upper positioning sleeve in the clamping member can be changed, and the lamp cup is clamped and fixed up and down by using the positioning disk and the upper positioning sleeve, which is convenient for quickly clamping the lamp cup. The positioning disk and the upper positioning sleeve are both independent components, so that components of different specifications and sizes can be manufactured for replacement, and thus lamp cup workpieces of different sizes can be adapted.

[0026] The two-axis lead screw module of the present invention has the functions of bidirectional movement in the X-axis and Y-axis directions, and can flexibly drive the polishing mechanism to change its position up, down, left and right, so as to adapt to the polishing of lamp cups of different specifications and sizes. The swing motor of the polishing mechanism drives multiple polishing units to slide up and down along the curved surface of the outer wall of the lamp cup through a crank-slider mechanism, so that the polishing wheel can fully contact the outer wall of the lamp cup. At the same time, with the lamp cup as the rotation power, the polishing wheel in the polishing unit is driven to complete the high-speed polishing operation in the way of up and down friction.

[0027] The lamp cup of the present invention drives the polishing wheel to rotate through friction, and the polishing effect is good. The pressure on the polishing track is pressurized by a pressure cylinder. The greater the pressure, the greater the friction force of the polishing wheel and the higher the polishing efficiency. The present invention can process various aspherical parts such as paraboloids, ellipses, spherical surfaces, etc. The processing size range is very wide, and the polishing angle and arc surface can be adjusted arbitrarily to meet the purpose of production and processing requirements.

Detailed implementation manners

[0038] The following describes in detail the specific implementation manners of the present invention with reference to the drawings:

[0039] As Figures 2 to 9 shown, the outer wall polishing machine for lamp cups includes a polishing platform 1, a rotary clamping mechanism 3 for driving the lamp cup 2 to rotate, a two-axis motion module 4, and a polishing mechanism 5 controlled by the two-axis motion module 4. The polishing platform 1 is a table structure made of steel, with table legs. The polishing platform 1 is used to support the rotary clamping mechanism 3 and the two-axis motion module 4. The two-axis motion module 4 can drive the polishing mechanism 5 to move in the up, down, left, and right directions to adapt to lamp cups 2 of different sizes. The polishing mechanism 5 is used to uniformly polish the outer wall of the lamp cup 2.

[0040] The rotary clamping mechanism 3 is arranged below the polishing platform 1, and the lamp cup 2 is detachably arranged on the rotary clamping mechanism 3 to realize the disassembly and assembly of the lamp cup 2. The rotary clamping mechanism 3 includes a fixed cylinder 31, a column 32 rotatably arranged in the fixed cylinder 31, and a drive motor 33 for driving the column 32 to rotate. The fixed cylinder 31 and the drive motor 33 are spaced apart below the polishing platform 1. The column 32 vertically penetrates the fixed cylinder 31, and the column 32 and the fixed cylinder 31 are rotatably connected through a bearing.

[0041] To achieve the rotation of the column 32, the lower end of the column 32 extends out of the fixed cylinder 31 and is driven by a belt by the driving motor 33. That is, belt pulleys are arranged on the lower end of the column 32 and the output shaft of the driving motor 33, and the two belt pulleys are driven by a belt, and the driving motor 33 can drive the column 32 to operate.

[0042] The lamp cup 2 is arranged above the polishing platform 1. To achieve the installation of the lamp cup 2, the upper end of the column 32 extends out of the fixed cylinder 31 and extends above the polishing platform 1. The column 32 located above the polishing platform 1 is a threaded rod structure, and a clamping member 6 is detachably arranged at the upper end of the column 32. The column 32 is detachably connected to the lamp cup 2 through the clamping member 6.

[0043] The clamping member 6 is used to clamp and fix the lamp cup 2. The clamping member 6 includes a lower positioning sleeve 61, a positioning disc 62 and an upper positioning sleeve 63. The cross section of the lower positioning sleeve 61 is convex-shaped, the cross section of the upper positioning sleeve 63 is inverted convex-shaped, and the size of the lower positioning sleeve 61 is larger than that of the upper positioning sleeve 63. The upper positioning sleeve 63 and the lower positioning sleeve 61 are arranged at intervals up and down on the column 32 and are threadedly connected to the column 32. Therefore, the positions and spacings of the upper positioning sleeve 63 and the lower positioning sleeve 61 on the column 32 can be adjusted.

[0044] A positioning disc 62 is coaxially arranged on the lower positioning sleeve 61. The positioning disc 62 is an independent component. The positioning disc 62 is directly sleeved at the shoulder of the lower positioning sleeve 61, so that the positioning disc 62 can be limited to prevent it from moving downward. The edge of the positioning disc 62 is a stepped structure, which can be adapted to the port 202 of the lamp cup 2. To fix the positioning disc 62, a locking ring 7 is threadedly connected to the lower positioning sleeve 61, and the locking ring 7 is used to press the positioning disc 62 to achieve fixation.

[0045] When the lamp cup 2 is installed, the lamp cup 2 is inverted between the upper positioning sleeve 63 and the positioning disc 62. First, the lamp cup 2 is inverted on the positioning disc 62, and the edge of the port 202 of the lamp cup 2 abuts against the stepped edge of the positioning disc 62 to prevent the lamp cup 2 from radially shaking. At this time, the column 32 is exactly corresponding to the central hole 201 of the lamp cup 2. The upper positioning sleeve 63 is screwed into the upper end of the column 32, and then the upper positioning sleeve 63 is inserted into the central hole 201 of the lamp cup 2. The upper positioning sleeve 63 can press the lamp cup 2 downward to achieve fixation and prevent the lamp cup 2 from axially moving. Thus, the lamp cup 2 and the column 32 can be connected and fixed, and the rotation of the column 32 drives the lamp cup 2 to operate together. The port 202 and the central hole 201 of the lamp cup 2 here are both prior arts and will not be elaborated here.

[0046] Above the polishing platform 1, a mounting frame 8 is vertically arranged. The mounting frame 8 is a portal frame. Above the mounting frame 8 is a plate body, and on both sides of the mounting frame 8 are shaft bodies. A two-axis motion module 4 is arranged on the mounting frame 8. The two-axis motion module 4 includes a motion mechanism in the X direction and a motion mechanism in the Y direction. The two-axis motion module 4 includes a longitudinal lead screw module 9 and a transverse lead screw module 10. The longitudinal lead screw module 9 can drive the transverse lead screw module 10 to move up and down. A polishing mechanism 5 is arranged on the two-axis motion module 4. The polishing mechanism 5 is connected to the transverse lead screw module 10 and can drive the polishing mechanism 5 to move left and right. Furthermore, the polishing mechanism 5 can move bidirectionally along the X-axis and Y-axis to adapt to lamp cup 2 workpieces of different sizes and shapes.

[0047] In this embodiment, the longitudinal lead screw module 9 is vertically arranged at the top of the mounting frame 8. The longitudinal lead screw module 9 is an electric lead screw lift, which includes a motor and a worm lead screw lift controlled by the motor. The motor can drive the lead screw to move up and down. The longitudinal lead screw module 9 is connected downward to the transverse lead screw module 10, and thus can drive the transverse lead screw module 10 to move up and down. The transverse lead screw module 10 is arranged between the two sides of the mounting frame 8. Furthermore, the transverse lead screw module 10 can move up and down along the mounting frame 8, which can provide guidance for the movement of the transverse lead screw module 10.

[0048] The transverse lead screw module 10 includes a transverse lead screw 101, transverse optical rods 102 and a transverse moving plate 103. The transverse lead screw 101 is arranged horizontally. The transverse optical rods 102 are arranged at intervals above and below the transverse lead screw 101. Furthermore, the number of transverse optical rods 102 is two, and the transverse optical rods 102 are arranged in parallel with the transverse lead screw 101. Vertical plates 11 are arranged between the transverse optical rods 102 and the transverse lead screw 101. The number of vertical plates 11 is two and they are located at the ends of the transverse lead screw 101. Through the vertical plates 11, the transverse optical rods 102 can be connected to the transverse lead screw 101. The transverse lead screw 101 is rotatably connected to the vertical plates 11, and the transverse optical rods 102 are fixedly connected to the vertical plates 11.

[0049] The vertical plates 11 correspond to the two sides of the mounting frame 8. A sliding sleeve is arranged above and below each vertical plate 11. The sliding sleeve is sleeved on the side of the mounting frame 8. Furthermore, the vertical plate 11 can slide up and down along the mounting frame 8, driving the transverse optical rods 102 and the transverse lead screw 101 to move up and down together. A lifting plate 12 is arranged between the two vertical plates 11 on both sides. The lifting plate 12 is formed by welding a rectangular long plate and a rectangular connecting block. The longitudinal section of the lifting plate 12 is in the shape of "ㅏ". The longitudinal lead screw module 9 is connected downward to the lifting plate 12, and thus can drive the transverse lead screw module 10 to move up and down.

[0050] A transverse lead screw 101 meshes with a transverse moving plate 103. The upper and lower sides of the transverse moving plate 103 are slidably connected to a transverse optical rod 102. By rotating the transverse lead screw 101, the transverse moving plate 103 can be driven to translate left and right. In order to rotate the transverse lead screw 101, one end of the transverse lead screw 101 extends out of the vertical plate 11 and is connected to a handwheel 14, which facilitates the control of the transverse lead screw 101. In this way, the longitudinal lead screw module 9 operates electrically and can automatically drive the transverse lead screw module 10 to move up and down. The transverse lead screw module 10 operates manually and requires manual operation to drive the transverse moving plate 103 to move left and right, thereby controlling the left and right movement of the polishing mechanism 5.

[0051] The polishing mechanism 5 is used to polish the lamp cup 2. The polishing mechanism 5 includes a movable plate 15, a polishing track 16, a swing motor 17, a polishing unit 18 controlled by the swing motor 17, and a connecting plate 19. The movable plate 15 is connected to the two-axis motion module 4. Specifically, the transverse lead screw module 10 is connected to the movable plate 15, that is, the transverse moving plate 103 in the transverse lead screw module 10 is bolted to the movable plate 15. Thus, the movable plate 15 is controlled by the transverse lead screw module 10. Driven by the transverse lead screw module 10, the movable plate 15 is caused to move horizontally left and right along the mounting frame 8.

[0052] The polishing track 16 is a curved arc-shaped plate structure. The curve of the polishing track 16 is consistent with the outer wall curve of the lamp cup 2. There is a gap between the polishing track 16 and the outer wall of the lamp cup 2, and it does not contact the outer wall of the lamp cup 2. The upper end of the polishing track 16 is hinged to the movable plate 15, and the lower end is connected to one side of the mounting frame 8 through a pressure cylinder 20.

[0053] Specifically, a cylinder sliding sleeve 21 with a hand-tightening bolt is slidably arranged on one side of the mounting frame 8. The cylinder sliding sleeve 21 moves up and down along the mounting frame 8. One end of the hand-tightening bolt on the cylinder sliding sleeve 21 passes through the side wall of the cylinder sliding sleeve 21 and abuts against the mounting frame 8. Tightening the hand-tightening bolt fixes the cylinder sliding sleeve 21. Conversely, the cylinder sliding sleeve 21 can move up and down on one side of the mounting frame 8. The pressure cylinder 20 is hinged to the cylinder sliding sleeve 21. The piston rod of the pressure cylinder 20 is connected to the lower end of the polishing track 16, which can control the swing of the polishing track 16, and thus control the gap between the polishing track 16 and the outer wall of the lamp cup 2.

[0054] Three polishing units 18 reciprocally slide on the polishing track 16, and the three polishing units 18 are arranged at intervals. Since the radian of the polishing track 16 is the same as the radian of the outer wall of the lamp cup 2, the polishing unit 18 can slide up and down along the outer wall of the lamp cup 2. Thus, the sliding track of the polishing unit 18 is consistent with the outer wall curve of the lamp cup 2. Each polishing unit 18 is equipped with a rotatable polishing wheel 13. The three polishing wheels 13 are in contact with the outer wall of the lamp cup 2 and apply a certain pressure to the outer wall of the lamp cup 2, and the polishing wheels 13 reciprocally move up and down along the height direction of the lamp cup 2.

[0055] The polishing track 16 is in a curved “U” shape, and three polishing units 18 are arranged on the polishing track 16 to slide back and forth. Each polishing unit 18 includes a sliding plate 25, which penetrates the polishing track 16 and extends to both sides of the polishing track 16. The size of the sliding plate 25 extending to both sides of the polishing track 16 is larger than the width of the polishing track 16, and the sliding plate 25 slides along the polishing track 16 in an arc track. In this way, the sliding plate 25 can realize the free sliding of the polishing unit 18 on the polishing track 16.

[0056] In order to realize the joint control between the polishing units 18, the three polishing units 18 are connected together by a connecting plate 19, and then the three polishing units 18 slide synchronously, that is, a connecting plate 19 is detachably connected between the sliding disks 25 of the three polishing units 18. The three polishing units 18 are connected by the connecting plate 19, and the three polishing units 18 can move together along the polishing track 16. Here, the connecting plate 19 includes an arc-shaped bent plate and three cylindrical blocks evenly arranged on the bent plate, and the cross section of the bent plate and the cylindrical blocks is "E" shaped after being connected and combined.

[0057] In order to realize the reciprocating driving of the polishing unit 18, a swing motor 17 is arranged on the movable plate 15, and a crank slider mechanism 22 is arranged between the output shaft of the swing motor 17 and the connecting plate 19 to connect. The swing motor 17 drives the polishing unit 18 to reciprocate through the crank slider mechanism 22. Since the three polishing units 18 are linked and controlled through the connecting plate 19, the three polishing units 18 reciprocate along the polishing track 16 together.

[0058] The crank slider mechanism 22 is a prior art, in which an eccentric disk 221 is arranged on the output shaft of the swing motor 17, and a connecting rod 222 is used, and the connecting rod 222 is hingedly installed between the connecting plate 19 and the eccentric disk 221 to realize the transmission between the swing motor 17 and the polishing unit 18. One end of the connecting rod 222 is in a circular ring shape, and the circular ring end of the connecting rod 222 is sleeved on a cylindrical block on the connecting plate 19, which is closest to the eccentric disk 221, and is rotatably connected to the cylindrical block. The connecting rod 222 is a telescopic rod structure, and the sliding distance of the polishing unit 18 can be controlled by changing the length of the connecting rod 222. Patent Publication No. CN207326637U and Patent Publication No. CN117020911B both disclose the principle and structure of the crank slider mechanism 22, which will not be repeated here.

[0059] Each polishing unit 18 further includes a polishing rod 26 and a polishing wheel 13. When the polishing rod 26 is installed, a mounting plate 27 is detachably connected to the other side of the sliding disk 25 by screws, and the mounting plate 27 is attached to one side of the sliding disk 25. The longitudinal section of the mounting plate 27 is in the shape of "ㅏ", and the polishing rod 26 is arranged on the mounting plate 27. The polishing rod 26 includes an upper cylinder 261 and a lower rod 262. The upper cylinder 261 is threadedly connected to the mounting plate 27, and the upper end of the lower rod 262 is placed inside the upper cylinder 261 and rotatably connected to the upper cylinder 261. The lower end of the lower rod 262 extends out of the upper cylinder 261 to connect the polishing wheel 13, and the polishing wheel 13 is of a circular structure. In this way, the polishing wheel 13 can rotate on the polishing rod 26.

[0060] The principle of the present invention is as follows: The lamp cup 2 is inverted on the positioning disk 62, and then the upper positioning sleeve 63 is screwed onto the column 32. The upper positioning sleeve 63 is used to press the lamp cup 2, and then the upper positioning sleeve 63 cooperates with the positioning disk 62 to clamp the lamp cup 2, realizing the fixation of the lamp cup 2. The rotating clamping mechanism 3 is started, and the column 32 together with the lamp cup 2 is driven to rotate by the driving motor 33; on the basis of the rotation of the lamp cup 2, the pressure cylinder 20 is started to extend, driving the polishing track 16 to approach the lamp cup 2, and then the polishing wheel 13 presses against the outer wall of the lamp cup 2. Different extension lengths of the pressure cylinder 20 can change the friction force of the polishing wheel 13.

[0061] A friction force is generated between the polishing wheel 13 and the outer wall of the lamp cup 2, and then the outer wall of the lamp cup 2 is polished. The greater the friction force, the higher the polishing efficiency, and the polishing wheel 13 can rotate freely. When the polishing wheel 13 contacts the outer wall of the lamp cup 2, the swinging motor 17 is started, and the polishing wheel 13 is driven to swing up and down along the outer wall of the lamp cup 2 through the crank-slider mechanism 22, so that the polishing wheel 13 can fully contact the outer wall of the lamp cup 2, realizing a uniform polishing effect.
