Description

Technical Field

[0001] The present invention relates to the technical field related to precision parts processing, and in particular to a feeding device for precision parts processing. Background Art

[0002] The machine tool feed mechanism is mainly used to control the motion path, speed and positioning accuracy of the tool or workpiece. It is responsible for controlling the relative auxiliary motion between the tool and the workpiece during the cutting process, that is, the feed motion. Its purpose is to continuously cut new metal layers, thereby processing the entire workpiece surface. During the processing, the feed mechanism is precisely controlled so that the machine tool can perform linear or rotational motion according to the preset program to complete operations such as drilling, milling, and turning.

[0003] A ball screw is a mechanical transmission device that transmits motion and force through rolling elements. It consists of a screw and a ball nut. The balls roll between the screw and the nut to reduce friction and improve transmission efficiency. When the screw rotates, the balls in the ball nut roll in the thread grooves of the nut and the screw, thereby converting rotational motion into linear motion, and then realizing the feed motion of the processed parts. However, the screw that drives the nut seat and the guide rails that limit the processing table are currently exposed. Some smaller debris will have the risk of falling into and adhering to the outer periphery of the screw and the guide rails, causing the surface of the screw and the guide rails to be scratched, which in turn affects the accuracy of the screw and the guide rails themselves, causing the feed motion to swing and become unstable. Currently, air guns are added to the periphery of the machine tool to blow air to clean the machine tool processing table before and after part processing and feeding. This increases the labor intensity of workshop workers and reduces production efficiency. At the same time, manual cleaning is not thorough and the cleaning effect is low. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the air blast nozzle in the air blast cleaning assembly is used to clean the debris on the periphery of the rotating stepping screw. A plurality of precisely designed air blast nozzles are cleverly arranged in the key peripheral area of ​​the stepping screw, especially in the exposed section near the nut and the load end. A continuous clean compressed air flow is used to form a directional airflow barrier to protect the upper surface of the screw and also to clean the periphery of the screw. The cleaning plate in the twisting cleaning assembly is swung back and forth to clean the debris on the base guide rail, thereby improving the cleanliness of the base guide rail, achieving a stable and smooth feeding motion of the processing table, and improving the feeding stability of the processing table.

[0017] In the present invention, the fixed rotating shaft in the air blast cleaning assembly drives the rotating column to rotate synchronously. During the rotation process, the rotating column drives the arc-shaped limiting rod and the movable rod to move stably under the action of the T-shaped slide groove and the T-shaped slider through the corrugated limiting groove. The arc-shaped limiting rod drives the cleaning piston rod outside the rotating column to move back and forth through the connecting plate. The cleaning cylinder is blown with the air blast nozzle to achieve real-time cleaning effect on the debris on the top of the screw rod. The air blast can reduce the probability of debris falling into the screw rod and can also use the air blast to clean the debris that has adhered to the screw rod. It can ensure real-time air blast and has a powerful air blast effect on the screw rod.

[0018] In the present invention, the worm gear, rotating shaft, arc-shaped rotating plate and flip block in the twisting cleaning assembly drive the arc-shaped flip frame to perform reciprocating flipping motion, and the arc-shaped flip frame drives the cleaning plate to move synchronously through the U-shaped connecting plate. The cleaning brush under the cleaning plate sweeps and cleans the debris on the base guide rail to remove the debris on the base guide rail. The cleaning plate is a motion structure that swings back and forth, which can clean the debris remaining on the base guide rail from both sides. It has a strong debris cleaning ability for the base guide rail and a wide cleaning range, thereby improving the accuracy and quality of precision parts processing.

[0019] In the present invention, the servo motor drives the machining tool magazine seat on the driving screw to stably move up and down under the action of the side guide rails, so as to meet the processing needs of different precision parts on the top of the processing table. The output end of the stepper motor drives the stepper screw to rotate, and the processing table on the stepper screw realizes stable feeding processing under the limiting action of the base guide rail, so that the precision parts are fed to the tool under the machining tool magazine seat on the longitudinal plane, and the entire precision parts processing process is stable and smooth.

[0020] In the present invention, the fixed rotating shaft in the rotating cover is driven to rotate by the second gear, and the rotating column is driven to rotate synchronously during the rotation of the fixed rotating shaft. During the rotation of the rotating column, the arc-shaped limiting rod is driven to move horizontally back and forth through the corrugated limiting groove. The arc-shaped limiting rod cooperates with the cleaning piston rod through the connecting plate to drive the cleaning piston plate in the cleaning cylinder to reciprocate synchronously, so that the stepping screw can be cleaned by air blast regardless of the feeding direction of the processing table. The air blast cleaning can accompany the entire processing movement process, and the air blast cleaning eliminates the peripheral debris of the stepping screw, thereby improving the feeding stability of the processing table.

[0021] In the present invention, the rotating gear cooperates with the base rack plate and the supporting shaft to drive the worm in the cleaning frame to rotate synchronously, the worm drives the worm wheel on the rotating shaft to rotate, and the worm wheel will drive the arc-shaped rotating plate and the rotating shaft to move synchronously through the rotating shaft. The flip block on the rotating shaft moves in the arc-shaped flip frame, and the movement of the flip block will drive the arc-shaped flip frame to perform reciprocating flipping motion, so that the cleaning plate can scrape back and forth to clean the debris of the base guide rail. The cleaning plate performs a back and forth fan-shaped swinging motion with the base guide rail as the center, which greatly improves the cleaning effect of the base guide rail debris.

During the processing, the position of the precision parts is horizontally adjusted by the processing table 12, so that the precision parts on the top of the processing table 12 are adjusted to the tool position of the processing tool magazine seat 11, and the output end of the stepper motor 25 drives the stepping screw 20 to rotate. The processing table 12 on the stepping screw 20 realizes stable feeding processing under the limiting action of the base guide rail 21, so that the precision parts are fed to the tool under the processing tool magazine seat 11 in the longitudinal plane.

[0040] See Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 The machine tool base 22 is provided with a blast cleaning assembly at one end away from the driving screw 16 for cleaning the debris on the periphery of the stepping screw 20.

During the rotation of the fixed rotating shaft 33, it drives the rotating column 34 to rotate synchronously.

[0042] See Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 The outer periphery of the rotating column 34 is provided with a corrugated limit groove 35, and the machine tool base 22 is fixedly installed with a limit base 37 on one side of the bottom of the rotating column 34. The top of the limit base 37 is provided with a T-shaped slide groove 38, and a T-shaped slider 39 is slidably connected in the T-shaped slide groove 38. A movable rod 43 is fixedly installed on the top of the T-shaped slider 39. The cooperation of the T-shaped slide groove 38 and the T-shaped slider 39 allows the movable rod 43 to undergo stable horizontal reciprocating motion. One end of the movable rod 43 is fixedly installed with an arc limit rod 36 that matches the size of the corrugated limit groove 35, and the arc limit rod 36 moves in the corrugated limit groove 35.

When the cleaning piston plate 46 in the cleaning cylinder 40 on one side is aligned with the cleaning piston plate 46, the cleaning piston plate 46 in the cleaning cylinder 40 on one side is aligned with the cleaning piston plate 46. When negative pressure is generated inside the cleaning cylinder 40, the cleaning cylinder 40 draws in air from the air inlet pipe 47, and at this time, the cleaning piston plate 46 in the cleaning cylinder 40 on the other side generates positive pressure inside the cleaning cylinder 40.

As the arc-shaped rotating plate 56 rotates the flip block 58 on the rotating shaft to a horizontal state, the flip block 58 will be at the middle end position of the arc-shaped flip frame 62 in a vertical state, and the arc-shaped flip frame 62 moves to the side position of the worm gear 54, causing the cleaning plate 60 to swing and misalign, and so on and so forth, causing the cleaning plate 60 to swing back and forth on both sides of the top of the base guide rail 21.

[0048] Working principle: Precision parts are placed on the processing table 12, and the processing tool magazine seat 11 on the driving screw 16 is driven by the servo motor 15 to stably rise and fall under the action of the side guide rail 17, driving the processing tool magazine seat 11 to rise and fall above the processing table 12, so that the tools under the processing tool magazine seat 11 can meet the processing of different precision parts on the top of the processing table 12. During the processing, the position of the precision parts is horizontally adjusted by the processing table 12, so that the precision parts on the top of the processing table 12 are adjusted to the tool position of the processing tool magazine seat 11, and the stepping screw 20 is driven to rotate by the output end of the stepping motor 25. The processing table 12 on the stepping screw 20 realizes stable feeding processing under the limiting action of the base guide rail 21, so that the precision parts are fed to the tool under the processing tool magazine seat 11 in the longitudinal plane;

[0049] When the processing table 12 moves back and forth stably on the base guide rail 21, the stepping screw 20 drives the first gear 31 in the rotating cover 30 to rotate during the rotation process, and the first gear 31 engages to drive the second gear 32 in the rotating cover 30 to rotate synchronously, and the second gear 32 drives the fixed rotating shaft 33 in the rotating cover 30 to rotate. During the rotation of the fixed rotating shaft 33, it drives the rotating column 34 to rotate synchronously. During the rotation process, the rotating column 34 drives the arc-shaped limiting rod 36 to move back and forth horizontally through the corrugated limiting groove 35. The arc-shaped limiting rod 36 drives the movable rod 43 on the limiting base 37 to move stably under the action of the T-shaped slide groove 38 and the T-shaped slider 39. The arc-shaped limiting rod 36 drives the rotating column 34 outward through the connecting plate 44 The cleaning piston rod 45 of the cleaning cylinder 40 reciprocates, and the cleaning piston rod 45 drives the cleaning piston plate 46 in the cleaning cylinder 40 to reciprocate synchronously. When the cleaning piston plate 46 in the cleaning cylinder 40 on one side generates negative pressure inside the cleaning cylinder 40, the cleaning cylinder 40 sucks air from the air inlet pipe 47, and at this time, the cleaning piston plate 46 in the cleaning cylinder 40 on the other side generates positive pressure inside the cleaning cylinder 40. The cleaning cylinder 40 discharges the internal air through the blast nozzle 42 on the blast seat 41 from the air outlet pipe 48, and the blast nozzle 42 is used to clean the debris on the periphery of the rotating stepping screw 20. The processing table 12 moves on the smooth periphery of the stepping screw 20, and the generated debris will not damage the stepping screw 20, thereby improving the feeding stability of the processing table 12.

[0050] When the processing table 12 is fed back and forth on the base guide rail 21, the rotating gear 51 connected to the supporting shaft 52 on the cleaning frame 50 is movably engaged with the base rack plate 26 on the triangular fixed frame 23, and the rotating gear 51 will drive the worm 55 in the cleaning frame 50 to rotate synchronously through the supporting shaft 52. When the worm 55 rotates, it will synchronously drive the worm wheel 54 on the rotating shaft 53 to rotate. The worm wheel 54 will drive the arc-shaped rotating plate 56 at the top to rotate through the rotating shaft 53. The arc-shaped rotating plate 56 drives the rotating shaft 57 to move synchronously. The flip block 58 on the rotating shaft 57 is on the arc flip frame 6 2, the movement of the flip block 58 will drive the arc-shaped flip frame 62 to perform reciprocating flipping motion, and the arc-shaped flip frame 62 will drive the U-shaped connecting plate 63 on the base rotating shaft 61 to swing synchronously, and the U-shaped connecting plate 63 will drive the cleaning plate 60 to move synchronously, and the cleaning brush 64 under the cleaning plate 60 will sweep and clean the debris on the base guide rail 21, and clean the debris on the base guide rail 21 to prevent the debris from scratching the base guide rail 21, thereby affecting the stable effect of the feeding of the processing table 12, resulting in instability in the feeding process of the processing table 12, affecting the accuracy of precision parts processing, and reducing the quality of precision parts processing.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
