Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, and in particular, to a lathe chip collection device. Furthermore, it also relates to a lathe including the lathe chip collection device. Background Technology

[0002] A lathe is a machine tool that primarily uses a cutting tool to machine rotating workpieces. It can process straight cylinders, inclined cylinders, arcs, and various complex workpieces such as threads, grooves, and worm gears, and is one of the most commonly used pieces of equipment in machining. During the machining process, a lathe generates a large amount of workpiece debris, which is inconvenient to clean and collect, and can easily fly and cause injury.

[0003] In existing technologies, a removable drawer is typically installed between the two support frames of a bench lathe, or a baffle is installed on the side of the lathe to collect and protect against debris. For example, Chinese Patent CN214817005U discloses a lathe with an automatic debris collection structure, including a lathe, a debris collection box, and a collection drawer. An electric telescopic rod is fixedly connected to the left side of the front face of the lathe, and a spray plate is fixedly connected to the right end of the electric telescopic rod. An air inlet box is fixedly connected to the rear end of the spray plate at the middle of the upper face of the lathe. A debris collection box is fixedly connected to the lower right side of the lathe, and a connecting plate is fixedly connected to the upper left side of the debris collection box. Rollers are rotatably connected to the lower outer side of the debris collection box, and a limiting groove is provided at the upper right side of the debris collection box. This patent, through the collection drawer, baffle, debris collection box, and protective plate, can process the debris collected in the debris collection box during the machine tool's machining of the workpiece and can prevent debris from splashing to a certain extent. However, the following problems still exist:

[0004] 1. Ineffective collection of metal shavings. When machining metal ingots on a lathe, shavings can fall into the equipment through the lathe's gaps, posing a risk of short circuits to electrical devices such as motors, relays, and power supplies, causing damage to the equipment and increasing maintenance costs. Shavings entering the lead screw and guide rails can cause jamming or wear, affecting the lathe's accuracy and lifespan. Cleaning during lathe machining is also very unsafe. Coolant is often added during lathe machining to cool and lubricate the workpiece, and the coolant can spill directly onto the floor, causing pollution to the workshop floor and making cleaning inconvenient.

[0005] 2. Ineffective in preventing metal shavings from flying. During operation, metal shavings may fly, and the high temperature generated by friction between the sample and the cutting tool during high-speed rotation can cause burns to the skin, posing a safety hazard to the operator.

[0006] 3. The recovery rate of precious metal scraps such as gold and silver is low. In particular, when gold ingots are polished with stainless steel knives, gold scraps will adhere to the edge of the ingot. During the high-speed rotation of the three-jaw chuck, they are very easy to splash or fall off. Because the scraps are small and dark in color, they are not easy to find, resulting in a low recovery rate and economic losses. Utility Model Content

[0007] This invention provides a lathe chip collection device to solve the technical problems in the prior art where chip splashing during lathe machining causes chips to easily enter the lathe, resulting in lathe damage and low chip recovery rate.

[0008] According to one aspect of the present invention, a lathe chip collection device is provided, comprising a collection box and a fixing member, the fixing member being used to connect to the collection box and position the collection box on the lathe.

[0009] The collection box is used to be installed between the workpiece and the cutting tool for chip collection. The collection box includes a first end for the workpiece to pass through and a second end for the cutting tool to pass through, and a space is formed between the first end and the second end to contain the machining surface of the workpiece.

[0010] Furthermore, the workpiece to be processed is clamped and fixed by a chuck, and the first end of the collection box has an open structure, the inner contour of which is larger than the outer contour of the chuck.

[0011] Furthermore, the second end of the collection box includes a cutting plate with a cutting inlet.

[0012] The fixing component is used to install the collection box at a position where the center line of the inlet coincides with the axis of the chuck, and the size of the inlet is larger than the working range of the cutting tool.

[0013] Furthermore, a protective pad is installed on the feed plate, and the protective pad covers the feed port;

[0014] The protective pad has a feed hole for the lathe tool to pass through. The protective pad is made of elastic material and is used to elastically abut against the tool holder of the lathe tool, thereby sealing the feed hole and preventing debris from flying out of the feed hole.

[0015] Furthermore, the collection box also includes a bottom plate connected to the bottom of the feed plate, side plates connected to both sides of the feed plate, and a top plate located on the top of the feed plate. The bottom plate, side plates, top plate and feed plate form an enclosing structure to prevent debris generated from the machining surface of the workpiece from flying out.

[0016] At least one of the top plate, the feed plate, and the side plate has a transparent structure.

[0017] Furthermore, the top plate covers the side plate and the feed plate, and one end of the top plate is rotatably connected to the side plate or the feed plate.

[0018] Furthermore, a collection groove for collecting debris is provided in the base plate, and the side of the collection groove away from the feed plate is inclined downward toward the feed plate.

[0019] Furthermore, the base plate is provided with an elastic stop bar, which is installed on the edge of the base plate away from the feed plate.

[0020] Furthermore, the fixing component includes a fixing plate fixed to the feed plate and a locking component for locking the fixing plate on the lathe. The fixing plate is located on the side of the feed plate away from the base plate.

[0022] This utility model has the following beneficial effects:

[0023] This utility model discloses a lathe chip collection device. A collection box is positioned and installed on the lathe between the workpiece and the cutting tool using a fixing component. During machining, the collection box remains outside the machining surface of the workpiece, effectively preventing chips from falling into the lathe through gaps. This avoids short circuits in electrical equipment or damage to instruments, significantly reducing maintenance costs. It also prevents chips from causing the lathe to jam or wear, ensuring machining accuracy and extending its service life. Compared to existing technologies, it eliminates the need for manual cleaning or flushing of chips from the lathe gaps during machining, ensuring machining progress and avoiding ground pollution from flushing. Furthermore, the device prevents chips from splashing during machining, preventing injury to surrounding personnel and reducing safety hazards. It also facilitates chip collection and cleaning, greatly improving the recovery rate of precious metals such as gold and silver, and reducing economic losses. In addition, the device provides some protection for the workpiece and cutting tool, reducing the safety risks caused by accidents such as the workpiece being thrown out due to insecure clamping or the cutting tool shifting due to looseness.

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0033] The lathe chip collection device of this embodiment is used to collect chips from a bench lathe. The bench lathe includes a frame and a headstock, a feed mechanism, and a tailstock arranged sequentially along the length of the frame. A guide rail is installed on the frame along its length. The headstock, tailstock, and feed mechanism are all slidably connected to the guide rail. A chuck for clamping and fixing the workpiece to be processed is installed on the headstock. The chuck is controlled to rotate by a drive component in the headstock so as to drive the workpiece to be processed on the chuck to rotate synchronously. The feed mechanism includes an apron and a tool post fixed on the apron. The apron is slidably connected to the guide rail. The apron is also provided with a feed mechanism, which is used to control the rotation and travel of the cutting tool on the tool post so that the cutting tool contacts the workpiece to be processed.

[0034] like Figure 1As shown, the lathe chip collection device includes a collection box 100 and a fixing member 200. The fixing member 200 is used to connect to the collection box 100 and position the collection box 100 on the lathe. The collection box 100 is used to be installed between the workpiece and the cutting tool for chip collection. The collection box 100 includes a first end for the workpiece to pass through and a second end for the cutting tool to pass through. A space is formed between the first end and the second end to contain the machining surface of the workpiece. The collection box 100 is positioned and installed on the lathe between the workpiece and the cutting tool using the fixing component 200. During machining, the collection box 100 remains enclosed outside the machining surface of the workpiece, effectively preventing debris from falling into the lathe through gaps. This avoids short circuits in electrical equipment or damage to instruments, significantly reducing maintenance costs. It also prevents debris from causing the lathe to jam or wear, ensuring machining accuracy and extending its service life. Compared to existing technologies, it eliminates the need for manual cleaning or flushing of debris from the lathe gaps during machining, ensuring machining progress and avoiding ground pollution from flushing. Furthermore, this device blocks debris from splashing during machining, preventing injury to surrounding personnel and reducing safety hazards. It also facilitates debris collection and cleaning, greatly improving the recovery rate of precious metals such as gold and silver, and reducing economic losses. In addition, the device encloses the workpiece and the cutting tool within the collection box 100, which can also provide some protection for the workpiece and the cutting tool, reducing the safety risks caused by accidents such as the workpiece being thrown out due to insecure clamping or the cutting tool shifting due to loosening.

[0035] In use, the collection box 100 is placed between the spindle box and the feed mechanism on the frame, with the first end of the collection box 100 facing the spindle box. The position of the collection box 100 is adjusted so that the first and second ends can be passed through by the chuck and the cutting tool, respectively. Then, the fixing member 200 is positioned and connected to the slide box, so that the collection box 100 moves together with the slide box. The spindle box is started, so that the chuck clamps the workpiece and moves towards the feed mechanism. The chuck carries the workpiece through the first end of the collection box 100 and extends into the collection box 100. The slide box is controlled to move along the guide rail towards the chuck. After the workpiece is inserted into the collection box 100, the feed mechanism is controlled so that the cutting tool extends through the second end of the collection box 100 and contacts the workpiece for processing. Thus, during the processing, the processing surface of the workpiece is always inside the collection box 100, so as to achieve effective collection of debris during the processing.

[0036] The workpiece is held and fixed by a chuck and rotates synchronously with the chuck to facilitate polishing or grinding with a cutting tool. For example... Figure 1 and Figure 2As shown, the first end of the collection box 100 has an open structure. The inner contour of the open structure is larger than the outer contour of the chuck. Preferably, in this embodiment, the length of the open structure is not less than twice the diameter of the chuck, the depth is not less than the length of the workpiece extending out of the chuck, and the width is greater than the maximum vertical height of the chuck. This provides sufficient space for the rotation of the chuck and increases the space inside the collection box 100 to collect more debris. In use, the first end of the collection box 100 is set towards the chuck so that the chuck carrying the workpiece extends into the collection box 100 through the first end. This ensures that the chuck and / or the workpiece are contained within the collection box 100 in both the circumferential and axial directions, guaranteeing that the processing surface of the workpiece is surrounded by the collection box 100. This prevents debris generated during processing from flying out of the collection box 100. Furthermore, setting the first end of the collection box 100 to have a larger open structure also prevents the chuck from touching the inner wall of the collection box 100 during rotation, avoiding damage to the collection box 100 and improving the service life of the device. In this embodiment, the first end of the collection box 100 is a square opening structure; alternatively, the first end of the collection box 100 may also be a rectangular opening structure or a circular opening structure.

[0037] The cutting tool of a bench lathe is fixed by a tool post, which is mounted on the apron. During machining operations, the angle and distance between the cutting tool and the workpiece are adjusted by the feed mechanism. Figure 1 and Figure 2 As shown, the second end of the collection box 100 includes a feed plate 101 with a feed port. A cutting tool can enter the collection box 100 through the feed port. The fixing member 200 is used to install the collection box 100 at a position where the center line of the feed port coincides with the axis of the chuck, so that the cutting tool can contact the workpiece on the chuck for machining. Preferably, the size of the feed port is larger than the working range of the cutting tool, ensuring that the cutting tool can pass smoothly while preventing the cutting tool from contacting the inner wall of the collection box 100 and avoiding damage to the collection box 100.

[0038] like Figure 1 and Figure 2 As shown, a protective pad 1011 is installed on the feed plate 101, covering the feed port. The protective pad 1011 has a feed hole 1012, which is a strip-shaped hole adapted to the shape and movement trajectory of the cutting tool. The size of the feed hole 1012 is larger than the size of the cutting tool. Since the working end of the cutting tool is inclined relative to the workpiece during use, the feed hole 1012 on the protective pad 1011 is also inclined to allow the cutting tool to extend into the collection box 100 through the feed hole 1012. Preferably, the feed hole 1012 is inclined at 45° to the feed plate 101. Preferably, the thickness of the protective pad 1011 can be 2 cm.

[0039] The protective pad 1011 is made of an elastic material to elastically abut against the tool holder of the lathe tool. On the one hand, the elastic material of the protective pad 1011 has a certain degree of flexibility, so it will not obstruct the operation of the lathe tool extending into the collection box 100, making it easy for the lathe tool to enter the collection box 100 for operation. On the other hand, the elastic material of the protective pad 1011 can seal the tool inlet hole 1012 and block the debris generated during machining in the collection box 100, preventing the debris from flying out from the tool inlet hole 1012, thus enhancing the protective and collection effect of the collection box 100. Preferably, the protective pad 1011 is a rubber pad.

[0040] like Figure 1 and Figure 2 As shown, the collection box 100 also includes a bottom plate 102 connected to the bottom of the feed plate 101, side plates 103 connected to both sides of the feed plate 101, and a top plate 104 disposed on the top of the feed plate 101. Specifically, in this embodiment, the two side plates 103 are fixedly connected to the feed plate 101 to protect both sides of the machining surface of the workpiece to be machined. The top plate 104 is covered on the side plates 103 and the top plate 104 and is rotatably connected to one of the side plates 103 to protect the top of the machining surface of the workpiece to be machined. The bottom plate 102 is detachably installed on the feed plate 101 and the side plates 103 to receive debris. The top plate 104 is longer and wider than the side plate 103 to increase the protective area. The top plate 104 and the side plate 103 are rotatably connected by hinges, allowing them to be opened after processing to clean debris from the inner walls of the side plate 103 and the feed plate 101, causing the debris to fall onto the bottom plate 102 for collection. The bottom plate 102 is detachably connected, allowing it to be easily removed after processing to clean or recycle the collected debris, improving the flexibility of the device. Optionally, the top plate 104 can also be rotatably connected to itself; optionally, the top plate 104 is equipped with a latch to lock it in place, preventing displacement or opening caused by shaking during processing; optionally, the top plate 104 is equipped with a handle for easy opening and closing.

[0041] Preferably, at least one of the top plate 104, the feed plate 101, and the side plate 103 has a transparent structure. In this embodiment, the top plate 104 is entirely a transparent plate, and the bottom plate 102, the side plate 103, and the feed plate 101 all include steel plates and transparent plates fixed to the steel plates. The steel plate of the side plate 103 is located on the side closest to the bottom plate 102 and the feed plate 101, and the steel plate of the feed plate 101 is located on the side closest to the bottom plate 102. By setting the collection box 100 as a structure combining steel plates and transparent plates, while ensuring structural strength, it is possible to observe the processing of the workpiece to be processed and the collection of debris inside the collection box 100, facilitating timely operation. Preferably, the transparent plate is made of acrylic sheet or high-strength glass. Optionally, the top plate 104, the bottom plate 102, the feed plate 101, and the side plate 103 can all be steel plates, or the top plate 104, the bottom plate 102, the feed plate 101, and the side plate 103 can all be transparent plates.

[0042] like Figure 1 and Figure 3 As shown, a collection groove 1021 is provided in the base plate 102 to accommodate more debris and improve debris collection efficiency. The end of the base plate 102 away from the feed plate 101 slopes downwards towards the feed plate 101 to further increase the volume of the collection groove 1021 and guide the debris, allowing it to fall into the collection groove 1021 along the inclined surface, further improving debris collection efficiency. The inclined surface also facilitates emptying the debris from the collection groove 1021 for easy recycling. Furthermore, it prevents debris from flying out towards the chuck at the bottom, enhancing the debris collection effect.

[0043] Preferably, the base plate 102 is provided with an elastic baffle strip, which is installed on the edge of the base plate 102 away from the feed plate 101, so that the debris in the collection trough 1021 will not overflow from the opening at the first end. Preferably, the collection trough 1021 of the base plate 102 can also be covered with an elastic sealing gasket to reduce noise and debris splashing. Optionally, a weight sensor is installed at the bottom of the base plate to monitor the amount of debris collected in the collection trough 1021 in real time. The weight sensor is electrically connected to the alarm system and the control system. When the weight sensor detects that the weight of debris in the collection trough 1021 reaches a preset threshold, an alarm signal is automatically triggered to remind the operator to clean the collection trough 1021 or replace the base plate 102 in time.

[0044] like Figure 1 , Figure 3 and Figure 4As shown, the fixing member 200 includes a fixing plate 201 fixed to the feed plate 101 and a locking member 202 for locking the fixing plate 201 onto the lathe. The fixing plate 201 is located on the side of the feed plate 101 away from the base plate 102. Specifically, the fixing plate 201 has an L-shaped structure, with one end fixed to the feed plate 101 and the other end forming a U-shaped groove with the feed plate 101. The length of the fixing plate 201 is adapted to the length of the slide on the slide box, so that the fixing plate 201 can straddle the slide. The fixing plate 201 is engaged with the slide through the U-shaped groove formed with the feed plate 101 to position the collection box 100. A threaded hole is provided at the end of the fixing plate 201 away from the feed plate 101. The locking member 202 is installed in the threaded hole to fix the fixing plate 201 to the side end of the slide. Preferably, the locking member 202 is a screw.

[0045] According to another aspect of the present invention, a lathe is also included, comprising the aforementioned lathe chip collection device.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
