Description

Technical Field

[0001] The invention relates to the technical field of linear optical axis processing, and in particular to a linear optical axis manufacturing process. Background Art

[0002] In the modern precision machinery manufacturing industry, linear optical axes, as key transmission components, are widely used in high-end equipment such as CNC machine tools, automation equipment, and measuring instruments. Its manufacturing process has extremely high requirements for precision and process, and involves multiple complex processing links, including cutting, turning, heat treatment, grinding, and polishing. Among these links, polishing of round steel workpieces is an important part of the linear optical axis manufacturing process, which aims to improve the surface finish and precision of the workpiece.

[0003] However, a large amount of dust and waste will inevitably be generated during the polishing process. These dust and waste are mainly composed of tiny particles of workpiece materials (such as stainless steel, carbon steel, etc.), which are highly flammable and explosive and potentially harmful. The accumulation of dust not only affects the cleanliness of the production environment, but also exposes operators to the dust environment for a long time. Operators also face occupational health risks such as pneumoconiosis. In addition, the collection, storage and treatment of polishing waste is also a major problem. The random stacking of waste not only takes up production space, but also may cause environmental pollution.

[0004] Chinese patent announcement number CN216371642U discloses a highly efficient polishing device for round steel processing, which drives a lead screw to rotate via a hand wheel, and the lead screw pushes a clamping block to clamp and position the round steel in a rotating seat, which greatly improves the stability of the round steel during polishing. At the same time, a first motor drives the round steel to rotate via a rotating seat, which greatly improves the efficiency of round steel polishing.

[0005] However, in actual use, the dust generated during the polishing process cannot be effectively collected. These tiny particles will float in the air, not only polluting the environment of the production workshop, but also spreading to a wider area through the ventilation system, causing long-term impacts on the surrounding environment and employee health. Being in a high-dust environment for a long time not only affects the respiratory system and skin health of employees, but may also cause occupational diseases such as allergies and asthma.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figure 1-Figure 9 As shown, a linear optical axis manufacturing process includes a high-frequency heat treatment for preliminary treatment of round steel, straightening of the round steel after the heat treatment, rough grinding, fine grinding and polishing of the round steel after straightening, and an electroplating stage for electroplating the outer wall of the polished round steel, wherein the polishing process includes a housing 1, a plurality of polishing machines 2 arranged on the housing 1 for polishing the round steel workpiece, and a collecting mechanism 3 arranged on the housing 1 for automatically collecting waste chips generated during the polishing process, wherein the collecting mechanism 3 includes an exchange box 31, a dust box 32, an extension plate 33 arranged in the exchange box 31 in a horizontal straight direction and a drive for driving the extension plate 33 to slide The lifting plate 34 and the driving contact mechanism 4 for converting the rotational motion of the polishing machine 2 into the vertical sliding motion of the lifting plate 34, the polishing machine 2 is composed of a rotary driver, a transmission belt and a grinding block, the transmission belt is sleeved at the output end of the rotary driver, and the grinding block is sleeved and connected with the transmission belt. When the rotary driver rotates, the transmission belt can drive the grinding block to contact the round steel workpiece and grind the round steel workpiece. When the grinding block and the transmission belt rotate, the rotational force of the rotary driver can be transmitted to the transmission belt 41. The casing 1 is provided with a plurality of threaded fixing seats for pushing and limiting the round steel workpiece, and a clamping block for clamping the round steel workpiece is provided on the threaded fixing seat for sliding in a horizontal straight line direction.

[0037] When it is necessary to collect dust and waste chips of the round steel workpiece during the polishing process, the polishing machine 2 is started first, and then the lifting plate 34 can be driven to rise and fall in the vertical direction by driving the contact mechanism 4. During the vertical rise and fall of the lifting plate 34, the extension plate 33 can slide back and forth in the horizontal straight line direction in the exchange box 31. During the sliding process, the dust and waste chips can enter the dust collecting box 32, so that in the process of polishing the round steel workpiece, the waste chips and dust generated during polishing can be automatically collected, thereby avoiding the splashing of dust and waste chips, avoiding the inhalation of dust into the mouth and nose of the staff, and preventing the splashing of waste chips, thereby ensuring the cleanliness of the polishing area.

[0038] See also Figure 2-Figure 5 As shown, the collecting mechanism 3 also includes an exhaust pipe 35, a dust suction pipe 36, a filter 37 and a sliding box 38; the exhaust pipe 35 is arranged on the exchange box 31, and the exhaust pipe 35 is connected to the air outlet end of the exchange box 31; the dust suction pipe 36 is respectively arranged on the exchange box 31 and the dust collecting box 32; the filter 37 is arranged on the dust collecting box 32 in a horizontal straight sliding direction; the sliding box 38 is arranged on the dust collecting box 32 in a horizontal straight sliding direction and is located below the filter 37, and both the exhaust pipe 35 and the dust suction pipe 36 are provided with a one-way valve for controlling the entry and discharge of air.

[0039] When the lifting plate 34 descends in the vertical direction, the contact mechanism 4 can be driven to cause the extension plate 33 to slide in the horizontal straight line direction in the exchange box 31. During this process, the one-way valve in the exhaust pipe 35 can be closed and the one-way valve in the dust suction pipe 36 can be opened, so that the dust suction pipe 36 can be inhaled. During the inhalation, the dust or waste chips in the polishing area can be automatically inhaled. After inhalation, the dust or waste chips can be blocked and purified by the filter 37 provided in the dust collecting box 32, so that the waste chips can fall into the sliding box 38, and the dust can be purified by the filter 37. During the resetting process of the extension plate 33, the one-way valve in the dust suction pipe 36 is opened and the one-way valve in the exhaust pipe 35 is opened, so that the air in the exchange box 31 can be discharged through the exhaust pipe 35.

[0040] See also Figure 5-Figure 7 As shown, the driving contact mechanism 4 includes a first transmission belt 41, a mounting plate 42, a rotating rod 43 and a swing contact block 44; the first transmission belt 41 is arranged on the output shaft of the polishing machine 2; the mounting plate 42 is arranged on the housing 1 and has a pair; the rotating rod 43 is arranged between a pair of mounting plates 42 and is sleeved and connected with the first transmission belt 41; the swing contact block 44 is rotatably arranged on the rotating rod 43, the swing contact block 44 is coaxially fixed with the rotating rod 43, and the swing contact block 44 is used to contact the lifting plate 34 and cause the lifting plate 34 to descend in the vertical direction.

[0041] When the polishing machine 2 drives the grinding block for polishing, the rotating rod 43 set on the mounting plate 42 can be driven to rotate by the first transmission belt 41 during this process. When the rotating rod 43 rotates, the coaxially fixed swing contact block 44 can be rotated. When the swing contact block 44 rotates, it can contact the lifting plate 34 and cause the lifting plate 34 to descend in the vertical direction. When the swing contact block 44 continues to rotate and does not contact the lifting plate 34, the lifting plate 34 can perform a vertical reset action.

[0042] See also Figure 6 and Figure 7 As shown, the driving contact mechanism 4 also includes a displacement groove 45, a vertical guide rod 46, a sliding block 47 and a hinge rod 48; the displacement groove 45 is opened on the housing 1 and has a pair; the vertical guide rod 46 is arranged on the housing 1 and is used to limit the vertical sliding of the lifting plate 34; the sliding block 47 is slidably arranged on the displacement groove 45 in the horizontal straight line direction and has a pair; the hinge rod 48 is rotatably arranged on the lifting plate 34 and the sliding block 47, and the sliding block 47 has a pair, one of which is fixedly connected to the extension plate 33 arranged in the exchange box 31, and when the sliding block 47 slides, it is used to drive the extension plate 33 to slide in the horizontal straight line direction in the exchange box 31.

[0043] During the vertical descent of the lifting plate 34, it can slide stably along the vertical guide rod 46 with clearance fit, and can push the sliding block 47 by rotating the hinged rod 48. When the sliding block 47 is pushed, it can move relatively away in the horizontal straight direction along the displacement groove 45 provided on the casing 1. When the sliding block 47 performs a relatively away expansion movement, it can move the fixedly connected extension plate 33, thereby achieving the movement and restoration of the extension plate 33.

[0044] See also Figure 6 and Figure 7 As shown, the driving contact mechanism 4 also includes a limiting rod 49 and a return spring 491; the limiting rod 49 is arranged on the housing 1, and the limiting rod 49 and the lifting plate 34 are clearance-matched; the return spring 491 is arranged on the limiting rod 49, and the two ends of the return spring 491 are respectively fixed to the ends of the lifting plate 34 and the limiting rod 49.

[0045] When the swing contact block 44 contacts the lifting plate 34 and causes the lifting plate 34 to descend in the vertical direction, the return spring 491 can be compressed in this process. When the swing contact block 44 does not contact the lifting plate 34, the return spring 491 can be released.

[0046] See also Figure 3-Figure 6As shown, the linear optical axis manufacturing process also includes a cooling mechanism 5 for timely cooling the round steel workpiece after polishing; the cooling mechanism 5 includes a water pump 51, a contact rod 52, a displacement plate 53 and a water tank 54; the water pump 51 is arranged on the casing 1 and away from the side of the exchange box 31; the contact rod 52 is arranged in the water pump 51 in a horizontal linear sliding direction, and the contact rod 52 is used to contact the sliding block 47; the displacement plate 53 is arranged in the water pump 51 in a horizontal linear sliding direction, and the displacement plate 53 is fixedly connected to the contact rod 52; the water tank 54 is arranged on the casing 1 and has a pair of water tanks 54, and the water tank 54 is used to supply water to the inside of the water pump 51.

[0047] When the sliding block 47 slides in a relatively horizontal straight direction, the sliding block 47 can be brought into contact with the contact rod 52, and the contact rod 52 can slide in a horizontal straight direction in the water pump 51. During the sliding process, the cooling water inside the water pump 51 can be sprayed onto the polished round steel workpiece, so that when the lifting plate 34 descends and the sliding block 47 moves relatively away, the cooling water inside the water pump 51 can be directly sprayed onto the polished round steel workpiece.

[0048] See also Figure 4-Figure 6 As shown, the cooling mechanism 5 also includes a water inlet pipe 55, a spray cooling pipe 56, a water permeable hole 57 and a collecting box 58; the water inlet pipe 55 is arranged at the water outlet end of the water storage tank 54, and the water outlet end of the water inlet pipe 55 is connected to the water inlet end of the water storage pump 51; the spray cooling pipe 56 is arranged at the water outlet end of the water storage pump 51, and the spray cooling pipe 56 is located above the round steel workpiece and has a pair; the water permeable hole 57 is opened on the casing 1, and the water permeable hole 57 is used to discharge the cooling water after spraying in time; the collecting box 58 is arranged on the casing 1, and the collecting box 58 is used to recycle the cooling water after spraying, and the water inlet pipe 55 and the spray cooling pipe 56 are both provided with a one-way valve for controlling the circulation of cooling water.

[0049] When the sliding block 47 contacts the contact rod 52 and causes the contact rod 52 to slide in the water pump 51, during this process, the one-way valve in the spray cooling pipe 56 opens and the one-way valve in the water inlet pipe 55 closes, so that the cooling water in the water pump 51 can be discharged through the spray cooling pipe 56 and sprayed onto the surface of the polished round steel workpiece; when the sliding block 47 does not contact the contact rod 52, the one-way valve in the water inlet pipe 55 opens and the one-way valve in the spray cooling pipe 56 closes, so that the cooling water in the water tank 54 can be replenished into the water pump 51.

[0050] See also Figure 5As shown, the cooling mechanism 5 also includes a stroke chamber 59 and a telescopic spring 591; the stroke chamber 59 is opened on the water pump 51, and the stroke chamber 59 is used for the displacement plate 53 and the contact rod 52 to slide in the horizontal straight direction; the telescopic spring 591 is arranged in the water pump 51, and the end of the telescopic spring 591 is fixed to the displacement plate 53.

[0051] When the contact rod 52 slides, it can slide along the stroke chamber 59 opened in the water pump 51, and the telescopic spring 591 can be squeezed by the displacement plate 53 during the sliding process. When the sliding block 47 is not in contact with the contact rod 52, the telescopic spring 591 can push the displacement plate 53 to slide and reset, driving the contact rod 52 back to its initial position.

[0052] See also Fig.10 As shown, the linear optical axis manufacturing process also includes a wiping mechanism 6 for wiping the round steel workpiece after cooling; the wiping mechanism 6 includes a wiping block 61, a rotating motor 62 and a bidirectional screw 63; a pair of horizontal linear sliding arrangements are arranged on the housing 1; the rotating motor 62 is arranged on the housing 1; the input end of the bidirectional screw 63 is connected to the output end of the rotating motor 62 through a coupling, and the bidirectional screw 63 is threadedly connected to the wiping block 61.

[0053] When it is necessary to wipe the cooling water on the surface of the round steel workpiece after spraying, first start the rotating motor 62. The rotating motor 62 can drive the bidirectional screw 63 to rotate. When the bidirectional screw 63 rotates, it can drive a pair of wiping blocks 61 to move relatively close until the wiping blocks 61 contact the surface of the round steel workpiece.

[0054] See also Fig.10 As shown, the wiping mechanism 6 also includes a mounting block 64 and a positioning rod 65; the mounting block 64 is arranged on the housing 1 and has a pair; the positioning rod 65 is arranged on the mounting block 64, and the positioning rod 65 is loosely matched with the wiping block 61 and is used to limit the sliding of the wiping block 61 in the horizontal straight direction.

[0055] When the wiping block 61 moves, it can be restricted by the positioning rod 65 to slide stably in the horizontal straight line direction, so that the movement process of the wiping block 61 is more stable.

[0056] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
