Description

Technical Field

[0001] The invention relates to the technical field of optical projection, in particular to an optical projection device for an optical grinding machine. Background Art

[0002] Optical grinding machine, also known as optical grinding machine or optical grinding machine, is a kind of equipment specially used for high-precision optical component processing. It is generally equipped with an optical projection device. The high-precision optical projection system of the optical projection device is used to accurately project the processing pattern onto the optical component to be processed, and guide the grinding wheel to process according to the predetermined trajectory, so that it can not only achieve high-precision shape processing, but also accurately correct the tiny defects on the surface of the component;

[0003] The optical projection device is one of the core devices on the optical grinding machine. In the optical projection device, there is generally a display screen for projection, and a convex lens that can be moved up, down, left, and right is provided on the display screen. The staff can magnify and observe the projected image on the display screen by moving the convex lens to improve the control of the accuracy of the workpiece;

[0004] However, in actual use, since the convex lens needs to be moved vertically, due to the high height of the optical grinder, the staff has to hold the convex lens all the time, which can easily cause arm pain. Therefore, a gear rack set is generally installed to drive the convex lens to rise and fall. When the gear and rack are in use, in order to reduce the friction between the gear and the rack, lubricating oil is applied between the gear and the rack. The friction between the gear and the rack is reduced by the lubricating oil. However, when applying the lubricating oil between the gear and the rack, manual application is usually adopted, which can easily lead to uneven application of the lubricating oil, resulting in waste of the lubricating oil and affecting the operation effect of the gear. For this reason, we propose an optical projection device for an optical grinding bed. Summary of the invention

[0008] Preferably, a limit plate is fixedly connected to the inner bottom wall between the transmission chamber and the oil chamber, and a fixed seat is fixedly connected to the side of the limit plate close to the gear B. A receiving groove is provided on the fixed seat, and a scraper is slidably connected in the receiving groove.

[0010] Preferably, a mounting rod is rotatably connected between the two mounting holes, a plurality of baffles are fixedly connected to the mounting rod, a plurality of limit springs are fixedly connected to the surfaces at both ends of the mounting rod through grooves, a clamping block is fixedly connected to the limit spring, and the clamping block is used in conjunction with the limit groove.

[0011] Preferably, a motor is fixedly connected to the mounting shell, and the output end of the motor is fixedly connected to the rotating shaft of gear A, an oil filling pipe connected to the oil chamber is fixedly connected to the top of the mounting shell, and the oil filling pipe is located above the limit frame, and a sealing plug is slidably connected inside the oil filling pipe.

[0012] Preferably, a control box is fixedly connected to the top of the mounting seat, a plurality of control buttons for controlling the operation of the motor are arranged on the top of the control box, and a control element and a lithium battery connected to the motor through wires are arranged in the control box.

[0013] Preferably, a mounting frame is fixedly connected to one side of the machine body, and a control host is rotatably connected to the bottom of the mounting frame away from one end of the machine body, and buttons and a screen are respectively provided on the control host.

[0014] Preferably, a top plate is fixedly connected to the top of the body, and slide grooves are provided on both sides of the top plate. A group of sliders are slidably connected in each of the slide grooves, and a blackout curtain is fixedly connected between each group of sliders via a metal chain.

[0015] Preferably, a load-bearing seat is provided below the machine body, both sides of the top of the load-bearing seat are fixedly connected with rails, and the machine body is slidably installed between the rails.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention adds lubricating oil into the oil chamber. When gear A rotates and cooperates with the rack to drive the mounting seat to rise and fall, gear A can synchronously drive gear B to rotate. At this time, the part of gear B located in the lubricating oil will rotate to contact gear A. At this time, gear B can be used to oil gear A. At the same time, since each tooth of gear B and gear A meshes with each other, gear B can evenly oil gear A during the rotation process. Since gear B rotates with gear A, it can automatically complete the oiling work when the device starts, and automatically stop the oiling work when it is not working, which effectively improves the auxiliary function of the device for the staff when operating;

[0018] 2. In the present invention, when gear B rotates, the tooth block of gear B will squeeze the scraper. At this time, since the tooth block of gear B and the top and bottom of the scraper are inclined surfaces, the upper and lower pressures will be converted into lateral forces, so that the scraper moves toward the receiving groove of the fixed seat. When the tooth block of gear B squeezes through the scraper, the installation spring starts to rebound, so that the scraper sticks to the surface of the tooth block of gear B and slides into the tooth groove of gear B. In this way, the scraper is used to scrape off the lubricating oil on gear B, avoiding the problem of too much lubricating oil attached to gear B, resulting in too much lubricating oil applied to gear A, and effectively reducing the waste of lubricating oil.

[0019] When the oil level in the oil tank is too high, the oil pump will automatically adjust the oil pressure to adjust the oil level, so that the oil pump will be more effective in preventing the oil from getting in the oil tank when the oil level is too high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8 The present invention provides a technical solution: an optical projection device for an optical grinding machine, comprising a body 1, a display screen 11 is provided on the body 1, and a camera 12 is fixedly connected to the bottom of the body 1, a mounting frame 13 is fixedly connected to one side of the body 1, and a control host 14 is rotatably connected to the bottom of the mounting frame 13 away from one end of the body 1, and buttons and a screen are respectively provided on the control host 14;

[0031] A top plate 2 is fixedly connected to the top of the body 1, and slide grooves 21 are provided on both sides of the top plate 2. A group of sliders 22 are slidably connected in each of the slide grooves 21, and a blackout curtain 23 is fixedly connected between each group of sliders 22 via a metal chain.

[0032] Furthermore, the body 1 is the main body of the optical projection device used for the optical grinding bed. The projection image can be collected through the camera 12 and the image is transmitted to the display screen 11. At this time, the precise size of the workpiece can be more intuitively known through the display screen 11, so as to make relevant adjustments for precise processing. The device can be controlled by the control host 14.

[0033] Furthermore, when using the device, the blackout curtain 23 can be pulled so that one side of the blackout curtain 23 drives the slider 22 connected thereto to move, so that the multiple sliders 22 in the slide groove 21 are separated from each other, thereby unfolding the blackout curtain 23. At this time, the top plate 2 and the blackout curtains 23 on both sides thereof cooperate to shade the display screen 11, making the image displayed on the display screen 11 more obvious.

[0034] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top and bottom of the body 1 on the side close to the display screen 11 are fixedly connected with a fixing frame 3, and the two fixing frames 3 are slidably connected with a limiting seat 31, and two connecting rods 33 are fixedly connected between the two limiting seats 31, and a rack 34 is provided on the connecting rod 33 close to the side of the mounting shell 5, and the rack 34 is meshed with the gear A53, and a handle 32 is fixedly connected to the limiting seat 31 close to the bottom of the display screen 11, and a mounting seat 4 is slidably connected between the two connecting rods 33, and a lens 41 is fixedly connected to the mounting seat 4, and a control box 42 is fixedly connected to the top of the mounting seat 4, and a plurality of control buttons for controlling the operation of a motor 55 are provided on the top of the control box 42, and a control element and a lithium battery connected to the motor 55 through wires are provided in the control box 42.

[0035] Furthermore, when observing some details of the image displayed on the display screen 11, the handle 32 can be held to drive the limit seat 31 and the connecting rod 33 to move horizontally along the fixing frame 3. At this time, the lateral position of the mounting seat 4 can be adjusted. Since it is a horizontal movement, the limit seat 31 can be stopped in time. At this time, the image on the display screen 11 in the area can be magnified through the lens 41 on the mounting seat 4 for a more detailed view. The rotation time and rotation direction of the motor 55 can be changed through the control button on the top of the control box 42, thereby controlling the vertical position of the mounting seat 4.

[0036] Combined with Figure 3 , Figure 4 and Figure 5 As shown, a mounting shell 5 is fixedly connected to one side of the mounting seat 4, and a transmission chamber 51 and an oil chamber 52 are respectively provided in the mounting shell 5, a gear A53 is rotatably connected in the transmission chamber 51, and a gear B54 meshing with the gear A53 is rotatably connected in the oil chamber 52, the oil chamber 52 is filled with lubricating oil, a motor 55 is fixedly connected to the mounting shell 5, and the output end of the motor 55 is fixedly docked with the rotating shaft of the gear A53, an oil filling pipe 56 connected to the oil chamber 52 is fixedly connected to the top of the mounting shell 5, and the oil filling pipe 56 is located above the limit frame 7, and a sealing plug 57 is slidably connected in the oil filling pipe 56.

[0037] Furthermore, when using the device, firstly, add a proper amount of lubricating oil into the oil chamber 52 through the oil filling pipe 56, so that the bottom quarter of the gear B54 is immersed in the lubricating oil, and then start the motor 55 to drive the gear A53 to rotate. At this time, during the rotation of the gear A53, it cooperates with the rack 34 on the connecting rod 33 to drive the mounting seat 4 to rise and fall. By changing the direction of the motor 55, the lifting direction of the mounting seat 4 can be changed. During the rotation of the gear A53, it can drive the gear B54 to rotate. At this time, due to the rotation of the gear B54 Part of the tooth block is immersed in the lubricating oil. When the gear B54 rotates, the lubricating oil can be brought up, so that when the gear A53 drives the gear B54 to rotate, the gear B54 is used to complete the lubricating oil application work on the gear A53. Then, the lubricating oil is brought to the rack 34 through the gear A53 to complete the oiling work. The lubricating oil can reduce the friction between the gear A53 and the rack 34. The gear B54 is made of rubber material, which has a relatively soft property. With the lubricating oil, it can reduce the friction between the gear A53 and the gear A53, thereby extending the service life of the gear A53.

[0038] Combined with Figure 5 and Figure 6 As shown, a limit plate 6 is fixedly connected to the inner bottom wall between the transmission chamber 51 and the oil chamber 52, and a fixed seat 61 is fixedly connected to the side of the limit plate 6 close to the gear B54. A receiving groove 62 is provided on the fixed seat 61, and a scraper 63 is slidably connected in the receiving groove 62. The scraper 63 is provided with inclined surfaces on the upper and lower sides of one end close to the gear B54, and a plurality of mounting springs 64 are fixedly connected between the scraper 63 and the inner wall of the receiving groove 62.

[0039] Furthermore, when the gear B54 rotates, the side surface of the tooth block of the gear B54 will exert pressure on the scraper 63. At this time, since the tooth block of the gear B54 and the top and bottom of the scraper 63 are all inclined surfaces, the upper and lower pressures will be converted into lateral forces, so that the scraper 63 moves toward the receiving groove 62 of the fixed seat 61. At this time, the scraper 63 will squeeze the installation spring 64 to make it contract. When the tooth block of the gear B54 squeezes through the scraper 63, the squeezing force of the tooth block of the gear B54 on the scraper 63 disappears, and the installation spring The spring 64 begins to rebound, pushing the scraper 63 to move out of the storage groove 62. At this time, the scraper 63 can slide into the tooth groove of the gear B54 along the surface of the tooth block of the gear B54, so that the scraper 63 can always be in contact with the surface of the gear B54. In this way, the scraper 63 is used to scrape off the excess lubricating oil on the gear B54 to prevent too much lubricating oil on the gear B54 and too much lubricating oil on the gear A53, which will cause the problem that when too much lubricating oil is applied to the rack 34, it will flow along the connecting rod 33.

[0040] Combined with Figure 5 , Figure 7 and Figure 8 As shown, the inner top wall of the oil chamber 52 is fixedly connected to a limiting frame 7, and the limiting frame 7 is provided with a guide groove 71. Both sides of the limiting frame 7 are provided with mounting holes 72, and the inner walls of the mounting holes 72 are provided with limiting grooves 73. A mounting rod 74 is rotatably connected between the two mounting holes 72, and a plurality of baffles 75 are fixedly connected to the mounting rod 74. The surfaces of both ends of the mounting rod 74 are fixedly connected with a plurality of limiting springs 76 through grooves, and a clamping block 77 is fixedly connected to the limiting spring 76, and the clamping block 77 is used in conjunction with the limiting groove 73.

[0041] Furthermore, when lubricating oil is added to the oil chamber 52 through the oil filling pipe 56, the lubricating oil will fall into the guide groove 71 of the limit frame 7, and then the lubricating oil will flow along the guide groove 71. When the lubricating oil flows to the position of the baffle 75, the baffle 75 will block the lubricating oil. At this time, the lubricating oil continues to accumulate at the baffle 75. When the lubricating oil accumulates to a certain extent, it will apply pressure to the baffle 75 and transmit the applied pressure to the mounting rod 74. At this time, the block 77 is squeezed by the inner wall of the limit groove 73, driving the limit spring 76 to contract, and the baffle 75 and the mounting rod 74 can be rotated at this time. During the rotation of the baffle 75, the lubricating oil can smoothly enter the oil chamber 52. After the mounting rod 74 rotates a certain angle, when another block 77 thereon moves to the position of the limit groove 73, the limit spring 76 rebounds and pushes the block 77 into the limit groove 73, so as to continue to limit the mounting rod 74. At this time, the other baffle 75 will continue to block the lubricating oil in the guide groove 71. Through the cooperation of the limit frame 7 and the baffle 75, the lubricating oil can be slowed down twice so that it can smoothly enter the oil chamber 52, thereby preventing the lubricating oil in the oil chamber 52 from splashing due to the impact force.

[0042] Combined with Figure 1 As shown, a load-bearing seat 8 is provided below the body 1 , both sides of the top of the load-bearing seat 8 are fixedly connected with rails 81 , and the body 1 is slidably installed between the rails 81 .

[0043] Furthermore, the load-bearing seat 8 is installed on the optical grinding bed, and the body 1 can be leveled through the track 81, and the protruding distance of the body 1 can be adjusted to improve its auxiliary function to the working environment and staff when in use.

[0044] Working principle: First, the main engine 14 is controlled to move the machine body 1 along the track 81 to adjust the position of the machine body 1. Then, the sealing plug 57 is opened, and lubricating oil is added to the oil chamber 52 through the oil filling pipe 56. The lubricating oil will fall into the guide groove 71 of the limit frame 7, and then the lubricating oil will flow along the guide groove 71. When the lubricating oil flows to the position of the baffle 75, the baffle 75 will block the lubricating oil. At this time, the lubricating oil continues to accumulate at the baffle 75. When the lubricating oil accumulates to a certain extent, it will apply pressure to the baffle 75 and transmit the applied pressure to the mounting rod 74. At this time, the block 77 is squeezed by the inner wall of the limit groove 73, driving the limit spring 76. The baffle plate 75 and the mounting rod 74 are retracted, and the baffle plate 75 and the mounting rod 74 are rotated. During the rotation of the baffle plate 75, the lubricating oil can smoothly enter the oil chamber 52. After the mounting rod 74 rotates to a certain angle, when another clamping block 77 on it moves to the position of the limiting groove 73, the limiting spring 76 rebounds and pushes the clamping block 77 into the limiting groove 73, and the mounting rod 74 can continue to be limited. At this time, the other baffle plate 75 will continue to block the lubricating oil in the guide groove 71 until the bottom quarter of the gear B54 is immersed in the lubricating oil, and then the lubricating oil can be stopped. Then, the sealing plug 57 is inserted back into the oil filling pipe 56 to seal the oil filling pipe 56.

[0045] Afterwards, the projection image can be collected by the camera 12 and transmitted to the display screen 11. At this time, the precise size of the workpiece can be more intuitively known through the display screen 11. At this time, the shading curtain 23 is pulled, so that one side of the shading curtain 23 drives the slider 22 connected thereto to move, so that the sliders 22 in the slide groove 21 are separated from each other, so that the shading curtain 23 is unfolded. At this time, the top plate 2 and the shading curtains 23 on both sides thereof cooperate to shade the display screen 11.

[0046] When it is necessary to observe some details of the image displayed on the display screen 11, the handle 32 is held to drive the limit seat 31 and the connecting rod 33 to move horizontally along the fixing frame 3. At this time, the lateral position of the mounting seat 4 can be adjusted, and the motor 55 can be started to drive the gear A53 to rotate. At this time, during the rotation of the gear A53, it cooperates with the rack 34 on the connecting rod 33 to drive the mounting seat 4 to move up and down. By changing the direction of the motor 55, the lifting direction of the mounting seat 4 can be changed. At this time, the image on the display screen 11 in the area can be magnified through the lens 41 on the mounting seat 4 for a more detailed view. At this time, the workpiece can be processed more finely through projection imaging;

[0047] During the rotation of gear A53, gear B54 can be driven to rotate. At this time, since part of the gear block of gear B54 is immersed in the lubricating oil, the lubricating oil can be brought up when gear B54 rotates. Thus, during the rotation of gear A53 driving gear B54, gear B54 is used to lubricate gear A53. Then, gear A53 brings the lubricating oil to rack 34, thus completing the lubrication work.

[0048] During the oiling process, when the gear B54 rotates, the side of the tooth block of the gear B54 will apply pressure to the scraper 63. At this time, since the tooth block of the gear B54 and the top and bottom of the scraper 63 are all inclined surfaces, the upper and lower pressures will be converted into lateral forces, so that the scraper 63 moves toward the receiving groove 62 of the fixed seat 61. At this time, the scraper 63 will squeeze the installation spring 64 to make it contract. When the tooth block of the gear B54 squeezes through the scraper 63, the squeezing force of the tooth block of the gear B54 on the scraper 63 disappears, and the installation spring 64 is installed. The spring 64 starts to rebound, pushing the scraper 63 to move out of the storage groove 62. At this time, the scraper 63 can slide into the tooth groove of the gear B54 along the surface of the tooth block of the gear B54, so that the scraper 63 can always be in contact with the surface of the gear B54, thereby using the scraper 63 to scrape off excess lubricating oil on the gear B54 to prevent excessive lubricating oil on the gear B54 and excessive lubricating oil on the gear A53, which will cause excessive lubricating oil to be applied to the rack 34 and flow along the connecting rod 33.
