A rotating shaft machining waste collecting device

Abstract

This invention relates to the field of industrial processing technology, specifically disclosing a waste collection device for rotary shaft machining, comprising a machine tool, a clamp on one side of the machine tool, and a guide rail on the top of the machine tool. A cutting mechanism is slidably mounted outside the guide rail. The device also includes a waste liquid tank and a waste collection tank located at the bottom of the machine tool. A locking assembly is slidably connected inside the machine tool. This waste collection device collects waste through the waste collection tank and turning fluid through the waste liquid tank. As more and more waste is collected in the waste collection tank, it moves downwards under gravity. Then, a driving assembly moves downwards, pushing the locking assembly upwards, thereby causing the locking plate to move upwards and limit the L-shaped plate, preventing the cutting mechanism from moving further and automatically stopping the cutting process. This reminds the operator to clean the waste in the waste collection tank, preventing waste from accumulating and overflowing due to untimely manual inspection, thus polluting the processing environment.

Description

Technical Field

[0001] This invention relates to the field of industrial processing technology, specifically to a waste collection device for shaft processing. Background Technology

[0002] A shaft is a type of shaft part that bears both bending moment (radial load) and torque (transmitting rotational power). It is the most common type of shaft in machinery. Shaft components are shaft-type components formed by high-temperature sintering, including solid shafts, hollow shafts, bushings, shaft cores, shaft flanges, shaft connection ends, and other small sintered metal parts that function as rotary transmission parts.

[0003] During the forming process of the shaft through machining processes such as turning, milling, and grinding, the turning process requires continuous spraying of turning fluid. The turning fluid is used to cool and lubricate the machining points, and simultaneously flush away the metal waste generated during machining, forming a solid-liquid mixture. Currently, the industry generally uses ordinary filter screens to achieve simple separation of cutting fluid and metal scrap. The filtered solid waste is directly collected in a collection box. The collection box needs to be inspected and cleaned manually on a regular basis. When the collection box is saturated with waste, if it is not cleaned in time, the excess waste is very likely to overflow the collection box. This not only pollutes the machine tool and the workshop processing environment, but the excess solid waste will also fall back into the filtered and purified cutting fluid, causing secondary contamination of the filtered cutting fluid and resulting in the cutting fluid not meeting the cleanliness standards. Summary of the Invention

[0004] The purpose of this invention is to provide a waste collection device for rotating shaft processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste collection device for rotating shaft machining, comprising a machine tool, a clamping fixture being provided on one side of the machine tool, and a guide rail being provided on the top of the machine tool, with a cutting mechanism slidably disposed outside the guide rail. It also includes a waste liquid tank and a waste material collection tank located at the bottom of the machine tool; The machine tool is internally slidably connected with a snap-fit ​​assembly, and the waste liquid tank is connected to the snap-fit ​​assembly via a drive assembly. When the waste collection box reaches the preset weight, the drive component drives the locking component to push it upward during the downward stroke of the waste collection box, so that the cutting mechanism stops moving during the cutting process.

[0006] Furthermore, an L-shaped plate is fixedly connected to the cutting mechanism, and the snap-fit ​​assembly includes a long strip plate fixed inside the machine tool. Multiple snap-fit ​​plates and multiple connecting plates are slidably arranged inside the long strip plate. A limit spring is fixedly connected to the bottom of the snap-fit ​​plate, and each limit spring is fixedly connected to each connecting plate.

[0007] Furthermore, the snap-fit ​​assembly also includes a support plate slidably disposed within the machine tool. The top of the support plate is fixedly connected to multiple fixing plates, each of which extends into the long strip and makes movable contact with each connecting plate.

[0008] Furthermore, the driving assembly includes a tapered plate rotatably disposed at the bottom of the support plate, the tapered plate having a guide hole, and a limit shaft slidably disposed within the guide hole; The drive assembly also includes a return plate slidably disposed at the bottom of the machine tool, two waste collection boxes located on top of the two return plates, and the bottom of the telescopic rod being detachably connected to the return plate; The drive assembly also includes a telescopic rod, the top end of which is fixedly connected to the limiting shaft.

[0009] Furthermore, guide rods are fixedly connected to the bottom perimeter of the shaped plate, and a fixing tube is sleeved on the outside of each guide rod, with a support spring installed inside each fixing tube.

[0010] Furthermore, it also includes a separation component, which is used to separate the waste generated by the cutting mechanism during the cutting of the shaft from the coolant; The separation component includes a permanent magnet rotatably disposed within the machine tool and located at the machine tool's discharge port. An arc-shaped plate is fixedly connected within the machine tool, and the arc-shaped plate is in movable contact with the permanent magnet. A rotating plate is rotatably disposed at the bottom of the arc-shaped plate.

[0011] Furthermore, an abutment plate is slidably disposed inside the rotating plate, which is in active contact with the surface of the permanent magnet, and an abutment spring is disposed inside the abutment plate. The rotating plate is located above the waste collection box.

[0012] Furthermore, the separation assembly also includes a drive gear fixed to the end of the permanent magnet, a driven gear adapted to the drive gear is fixedly connected to the end of the rotating plate, and a motor is provided inside the machine tool, with the output end of the motor fixedly connected to the drive gear.

[0013] Furthermore, a baffle is fixedly connected to the top of the U-shaped plate, and the baffle is in movable contact with the waste collection box.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the waste collection device for rotating shaft processing, Waste material is collected in the waste collection bin, and machining fluid is collected in the waste liquid bin. As more and more waste material is collected in the waste collection bin, it moves downwards due to gravity. Then, the drive component moves downwards, pushing the snap-fit ​​component upwards. This causes the snap-fit ​​plate to move upwards and limit the L-shaped plate, preventing the cutting mechanism from moving further and automatically stopping the cutting process. This reminds the operator to clean the waste material in the waste collection bin, avoiding the accumulation and overflow of waste material due to untimely manual inspection, which would pollute the processing environment.

[0015] The shaft is clamped by a fixture, and then the shaft is turned by sliding on the guide rail through a cutting mechanism. The resulting solid-liquid mixture waste enters the separation component, where solid impurities are adsorbed. The separated waste is collected in a waste collection tank, and the separated turning fluid enters a waste liquid tank for recycling and reuse. This completes the automatic separation of waste and coolant, improving separation efficiency.

[0016] After the return plate moves down with the weight of the waste material, it moves to the driven gear through the linkage component, which drives the telescopic rod to continue moving down, causing the connecting plate to move up further. This compresses the limit spring, generating an upward force on the locking plate, preventing the locking plate from falling back, ensuring that the locking plate extends stably and completes the limit locking of the L-shaped plate, avoiding insufficient locking force that would cause the cutting mechanism to continue moving, and improving the reliability of the limit.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-13The present invention provides a technical solution: a waste collection device for rotary shaft machining, including a machine tool 1, a clamp 2 provided on one side of the machine tool 1, and a guide rail 11 provided on the top of the machine tool 1. A cutting mechanism 3 is slidably arranged outside the guide rail 11. It also includes a waste liquid tank 41 and a waste collection box 42 provided at the bottom of the machine tool 1. A snap-fit ​​assembly is slidably connected inside the machine tool 1, and the waste liquid tank 41 and the snap-fit ​​assembly are connected by a drive assembly. When the waste collection box 42 reaches a preset weight, the snap-fit ​​assembly is pushed upward by the drive assembly during the downward stroke of the waste collection box 42, so that the cutting mechanism 3 stops moving during the cutting process.

[0022] Preferably, an L-shaped plate 31 is fixedly connected to the cutting mechanism 3. The snap-fit ​​assembly includes a long strip plate 51 fixed inside the machine tool 1. Multiple snap-fit ​​plates 52 and multiple connecting plates 54 are slidably arranged inside the long strip plate 51. Limiting springs 53 are fixedly connected to the bottom of the snap-fit ​​plates 52. Each limiting spring 53 is fixedly connected to each connecting plate 54. There are two L-shaped plates 31, which are respectively arranged on both sides of the cutting mechanism 3. The L-shaped plates 31 are suspended and do not contact the machine tool 1.

[0023] Preferably, the number of long strips 51 is the same as the number of L-shaped plates 31, and there are two of them, which are respectively arranged on both sides of the machine tool 1, with each long strip 51 corresponding to a L-shaped plate 31.

[0024] Preferably, the snap-fit ​​assembly further includes a support plate 56 slidably disposed within the machine tool 1. A plurality of fixing plates 55 are fixedly connected to the top of the support plate 56, and each fixing plate 55 extends into the long strip plate 51 and makes movable contact with each connecting plate 54.

[0025] Preferably, the drive assembly includes a tapered plate 63 rotatably disposed at the bottom of the support plate 56, the tapered plate 63 having a guide hole 631, and a limit shaft 64 slidably disposed within the guide hole 631; The drive assembly also includes a mold plate 65 that is slidably disposed at the bottom of the machine tool 1, and two waste collection boxes 42 located on top of the two mold plates 65.

[0026] Preferably, the drive assembly further includes a telescopic rod 61, the top end of which is fixedly connected to the limiting shaft 64, and the bottom end of which is detachably connected to the molded plate 65. After the waste collection box 42 is filled with waste, the telescopic rod 61 is detached from the molded plate 65, and the telescopic rod 61 is pushed upward to retract, so that there is no movement interference when the waste collection box 42 is pulled outward, which facilitates the cleaning of the waste collection box 42.

[0027] Preferably, there can be two drive components, each of which is set at the bottom of the corresponding long strip plate 51. By setting two sets of drive components at the bottom of the two support plates 56 respectively, the stability of the drive components moving down to push the support plates 56 up is increased, ensuring that multiple snap-fit ​​plates 52 can be stably extended to limit the L-shaped plate 31.

[0028] In another embodiment of the present invention, there are a total of four driving components, which are respectively arranged in pairs on both sides of the bottom of the two long strips 51. The two driving components at the bottom of each long strip 51 are symmetrically arranged, which further increases the stability of the snap-fit ​​plate 52 moving out.

[0029] Preferably, guide rods 67 are fixedly connected to the bottom perimeter of the molded plate 65, and a fixing tube 68 is sleeved on the outside of each guide rod 67. A support spring 62 is provided inside each fixing tube 68. The guide rods 67 are slidably inserted into the fixing tubes 68, and the support springs 62 provide a stable upward support force to the guide rods 67 and the molded plate 65.

[0030] Preferably, it also includes a separation component for separating the waste material generated during the cutting process of the cutting mechanism 3 on the rotating shaft from the coolant; The separation assembly includes a permanent magnet 71 rotatably disposed inside the machine tool 1, which is located at the discharge port of the machine tool 1. An arc plate 72 is fixedly connected inside the machine tool 1, and the arc plate 72 is in movable contact with the permanent magnet 71. A rotating plate 73 is rotatably disposed at the bottom of the arc plate 72.

[0031] Preferably, a contact plate 74 is slidably disposed inside the rotating plate 73, which is in active contact with the surface of the permanent magnet 71. The permanent magnet 71 is columnar, ensuring that the contact plate 74 is always in contact with the surface of the permanent magnet 71 and cleans the waste on the surface of the permanent magnet 71. A contact spring 75 is disposed inside the contact plate 74. The rotating plate 73 is located above the waste collection box 42. Multiple contact springs 75 can be disposed, and the two ends of the contact springs 75 are respectively connected to the contact plate 74 and the rotating plate 73. When the contact plate 74 slides into the rotating plate 73, it is pushed out by the compression force of the contact spring 75, while ensuring that the contact plate 74 does not detach from the rotating plate 73.

[0032] Preferably, the separation assembly further includes a drive gear 81 fixed to the end of the permanent magnet 71, a driven gear 82 adapted to the drive gear 81 fixedly connected to the end of the rotating plate 73, and a motor 83 provided in the machine tool 1, the output end of the motor 83 being fixedly connected to the drive gear 81.

[0033] In another embodiment of the present invention, there may be two sets of separation components, which are respectively arranged on both sides of the machine tool 1. The two motors 83 start and stop synchronously to ensure the synchronicity of the driving of the two sets of separation components. By rotating the two sets of separation components, the stability of the rotation of the permanent magnet 71 is increased. At the same time, the two sets of separation components are respectively connected to the driving components on both sides to drive the driving components to move further down and push the support plate 56 up to compress the limit spring 53.

[0034] Preferably, a baffle 66 is fixedly connected to the top of the U-shaped plate 65. The baffle 66 is in contact with the waste collection box 42. When the waste collection box 42 slides on the U-shaped plate 65, it limits the movement of the waste collection box 42 to ensure that the waste collection box 42 moves accurately to the bottom of the rotating plate 73 and the abutment plate 74.

[0035] In another embodiment provided by the present invention, a linkage component is also included, which is used to push the telescopic rod 61 to continue to move downward, so that the drive component pushes the locking component to continue to move upward, compressing the limiting spring 53. The linkage component includes a connecting rod 92, and a wedge plate 91 is fixedly connected to the end of the connecting rod 92. The telescopic rod 61 includes, from top to bottom, a sliding rod 611, a first connecting cylinder 612 and a second connecting cylinder 613. A second locking hole 97 is provided in the first connecting cylinder 612, and a first locking hole 96 is provided on the sliding rod 611. The wedge plate 91 is slidably disposed in the first locking hole 96 and the second locking hole 97.

[0036] Furthermore, the number of linkage components is set to be consistent with the number of drive components. When the driven gear 82 rotates, it pushes each set of linkage components to move, thereby pushing the corresponding number of drive components to move upward, so as to push the corresponding support plate 56 to continue to move upward to compress the limit spring 53, ensuring the stability of the latching plate 52 latching onto the L-shaped plate 31.

[0037] Preferably, the linkage assembly further includes a support rod 93 fixed on the U-shaped plate 65, a push plate 94 rotatably connected to the support rod 93, and an arc-shaped block 95 that is in movable contact with the push plate 94 fixedly connected to the surface of the driven gear 82.

[0038] During the turning of the shaft in this application, the shaft is first clamped and fixed on the machine tool 1 by the fixture 2. The cutting mechanism 3 moves back and forth along the guide rail 11 to cut the shaft. During the machining process, coolant is continuously sprayed to cool and lubricate the machining position. At the same time, it washes away the metal waste generated by cutting, forming a solid-liquid mixture that enters the machine tool 1. The permanent magnet 71 rotates continuously under the drive of the motor 83. When the solid-liquid mixture passes through the permanent magnet 71, the ferromagnetic metal waste will be attracted by the permanent magnet 71 and rotate with the permanent magnet 71. The coolant will pass through the discharge port of the machine tool 1 and fall directly into the waste liquid tank 41 to complete the recycling, thus realizing the automatic separation of solid and liquid. When the permanent magnet 71 rotates the adsorbed waste to the position of the arc plate 72, the arc plate 72 will scrape off the waste from the surface of the permanent magnet 71. The motor 83 drives the drive gear 81 to rotate, thereby causing the driven gear 82 to rotate in the opposite direction, driving the rotating plate 73 to rotate synchronously, thereby causing the abutment plate 74 to slide in contact with the surface of the permanent magnet 71 and the arc plate 72. Under the action of the abutment spring 75, the abutment plate 74 always adheres to the surface of the permanent magnet 71, scraping the waste off the surface of the permanent magnet 71. The scraped waste slides down the rotating plate 73 and the abutment plate 74 into the waste collection box 42 below for collection. As waste accumulates in the waste collection box 42, its overall weight gradually increases. The waste collection box 42 presses down on the forming plate 65, which compresses the support spring 62 downward along the guide rod 67. During the downward movement of the forming plate 65, the bottom end of the telescopic rod 61 moves downward simultaneously. The telescopic rod 61 pulls the conical plate 63 downward. As the conical plate 63 moves downward, the guide hole 631 slides along the limiting shaft 64, causing the conical plate 63 to rotate while moving downward. The top of the conical plate 63 gradually pushes the support plate 56 upward, and the support plate 56 drives the multiple fixed plates at the top. 55 moves upward synchronously, the fixed plate 55 pushes the corresponding connecting plate 54 upward, the connecting plate 54 compresses the limiting spring 53 and pushes the snap plate 52 to extend the long strip plate 51 upward. The snap plate 52 moves to the moving path of the L-shaped plate 31 and initially limits the movement of the cutting mechanism 3. If the cutting mechanism 3 continues to slide, it will be blocked by the snap plate 52 to stop turning the shaft, thereby stopping the generation of waste material and reminding the operator that the waste collection box 42 is about to be saturated. The snap plate 52 located at the bottom of the L-shaped plate 31 abuts against the L-shaped plate 31, causing the limiting spring 53 to be compressed. As the molded plate 65 moves downwards with the increasing weight of the waste material, the support rod 93 and the telescopic rod 61 drive the wedge plate 91, push plate 94, and connecting rod 92 to move downwards synchronously. When the molded plate 65 reaches the bottom, the bottom end of the push plate 94 moves to the arc-shaped block 95 of the driven gear 82. Through the rotation of the driven gear 82, the push plate 94 is pushed to rotate around the support rod 93. The other end of the push plate 94 pushes the connecting rod 92 and the wedge plate 91 to move, and the wedge plate 91 moves out of the first connecting rod. The sliding rod 611 moves downward within the first connecting cylinder 612 and the second connecting cylinder 613 through the first locking hole 96 and the second locking hole 97, thereby pulling the tapered plate 63 further downward and pushing the support plate 56 and the fixing plate 55 to continue moving upward. The fixing plate 55 pushes the connecting plate 54 upward to compress the limiting spring 53, so that the locking plate 52 is subjected to a greater upward pushing force. The locking plate 52 is stably locked between the L-shaped plates 31, completely restricting the movement of the cutting mechanism 3.

[0039] When cleaning up waste, the telescopic rod 61 is disassembled from the mold plate 65. The telescopic rod 61 is moved upward so that it moves out of the side of the waste collection box 42. The waste collection box 42 can then be pulled out from the mold plate 65 by pulling it laterally. After the weight of the mold plate 65 is reduced, it resets under the elastic force of the support spring 62, causing the components to move in the opposite direction. The locking plate 52 retracts into the long strip plate 51. At the same time, the wedge plate 91 is moved into the first locking hole 96 and the second locking hole 97. The cutting mechanism 3 can then resume movement and restart processing.

[0040] It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source, and this application is equipped with a control system for controlling the operation of the entire equipment.
