Technical Field

[0001] The utility model relates to machine tool manufacturing, in particular to a scraper device for a machine tool processing platform. Background Art

[0002] There are many products that can be processed by CNC machine tools, ranging from valve cores to columns and spindle boxes. The larger the product, the larger the processing platform required. The existing processing platforms are all equipped with a tooling for accommodating the product at the front end of the CNC machine tool or machining center, and enough space is left around the tooling to collect the waste chips during processing. The column is then fixed on the tooling, and the product is processed by the CNC machine tool or machining center.

[0003] This processing method adopted by the prior art has an unavoidable problem: a large space needs to be reserved so that the debris splashed during processing can be splashed into a designated area for easy collection and reuse. This processing form, due to the uncertainty of the processing size, cannot estimate the splashing area during workpiece processing. Therefore, it can be seen on site that the processing area of ​​the column occupies a large space, and the overall space occupied is large, which compresses the layout area of ​​other equipment. Utility Model Content

[0004] The utility model provides a scraper device for a machine tool processing platform, which can not only reduce the floor space of the entire platform, but also prevent debris from splashing into the external space during the processing stage of the column, and can effectively solve the above-mentioned problem.

[0005] The utility model is achieved in this way:

[0007] A longitudinal shielding structure, wherein the longitudinal shielding structure is arranged on a gantry, and the longitudinal shielding structure comprises a shielding flexible plate for shielding debris splashed out during the processing of the column, wherein the shielding flexible plate is rotatably wound in a winding drum, and the top of the shielding flexible plate is connected to a winding drum via a connecting cable passing around the gantry, and the winding drum is locked to the shaft core of a rotating motor, and when the rotating motor rotates, the rotating motor drives the connecting cable to slide via the winding drum, so that the connecting cable pulls the shielding flexible plate to gradually rotate out of the winding drum and move upward to form a shielding surface;

[0008] The scraping structure includes a scraping frame arranged at the bottom position of the vertical part of the gantry, the scraping frame is hollow, the shielding flexible plate passes through the scraping frame during movement, and a one-way scraping arm is arranged on the inner side of the scraping frame. When the shielding flexible plate moves downward, the iron filings adhered to the shielding flexible plate will be scraped off by the one-way scraping arm.

[0009] As a further improvement, the one-way scraper arm includes a bending arm connected to the inner side of the scraper frame, and a guide tool holder is integrally formed on the bending arm. The guide tool holder is tightly attached to the outer wall of the shielding flexible plate, and the guide tool holder is equipped with a scraper with a blade pointing to the lateral part of the gantry.

[0010] As a further improvement, the bending arm is fitted with the shielding flexible plate through a rotational fitting structure, and the rotational fitting structure includes a fine-tuning motor locked on the scraper frame, and a rotating shaft is clamped on the output shaft of the fine-tuning motor. The rotating shaft is fixedly connected to the bending arm, and the rotating shaft is arranged on the inner wall of the scraper frame through a clamping seat.

[0011] As a further improvement, the shielding flexible plate includes a chain plate wound on the winding drum, a ring buckle is locked on the top of the chain plate, the ring buckle is connected to the bottom of the connecting rope, and a high-density net is provided on the side of the chain plate close to the column, and the high-density net is used to intercept iron filings.

[0014] The beneficial effects of the utility model are:

[0015] The present invention adds a longitudinal shielding structure on the basis of the existing processing platform. Under normal conditions, the longitudinal shielding structure can be hidden by being folded inside the winding drum, so that quality inspectors and patrol personnel can directly see the conditions of each processing position. During processing, the cooperation of the rotating motor and the winding drum can be utilized to pull the shielding flexible plate out of the winding drum via the connecting rope, so that the shielding flexible plates on all four sides can form a complete blocking surface, so that the rectangular shielding surface surrounded by the shielding flexible plates can block the debris splashed during the column processing, limit the scope of the column processing to a smaller range, greatly reduce the scope of the column processing, reduce the overall footprint of the platform, and there is no need to worry about the phenomenon of debris splashing.

[0016] After the shielding flexible plate blocks the debris, some debris will adhere to the shielding flexible plate, thereby affecting the winding and recycling of the shielding flexible plate. In this regard, the present invention has a scraping structure based on the shielding flexible plate, and a one-way scraping arm is arranged on the scraping structure. The one-way scraping arm will only act on the shielding flexible plate in the descending stage. After the shielding flexible plate has played the role of a processing cycle, it needs to descend and be wound into the winding drum.

[0026] Reference Figure 1 to Figure 4 As shown, a scraper device for a machine tool processing platform includes: a longitudinal shielding structure, the longitudinal shielding structure is arranged on a gantry 11, the longitudinal shielding structure includes a shielding flexible plate 31 for shielding debris splashed out during the column processing, the shielding flexible plate 31 is rotated and wound in a winding drum 32, the top of the shielding flexible plate 31 is connected to a winding drum 34 through a connecting cable 33 bypassing the gantry 11, the winding drum 34 is locked to the shaft core of a rotating motor 35, and when the rotating motor 35 rotates, the rotating motor 35 drives the connecting rope 33 to slide through the winding drum 34, so that the connecting rope 33 pulls the shielding flexible plate 31 to gradually rotate out from the winding drum 32 and move upward to form a shielding surface; the scraping structure includes a scraping frame 41 arranged at the bottom position of the vertical part of the gantry 11, and the scraping frame 41 is hollow. The shielding flexible plate 31 passes through the scraping frame 41 during the movement. A one-way scraping arm 42 is arranged on the inner side of the scraping frame 41. When the shielding flexible plate 31 moves downward, the iron filings adhered to the shielding flexible plate 31 will be scraped off by the one-way scraping arm 42.

[0027] In this embodiment, the product processed on the processing platform is a column. The shape and structure of the column itself are relatively large. After the column is installed, it needs to be processed. During the processing stage, it is processed by a CNC machine. During the processing, a lot of debris will be splashed. In the prior art, the entire processing platform is set to be very large, so that there is enough space to accommodate the debris. However, this embodiment adds a longitudinal shielding structure on the basis of the existing processing platform. The longitudinal shielding structure can be hidden by being folded inside the winding drum 32 under normal conditions, so that the quality The inspection and patrol personnel can directly see the situation of each processing position, and during processing, the rotating motor 35 and the winding drum 34 can be used to pull the shielding flexible plate 31 out of the winding drum 32 through the connecting rope 33, so that the shielding flexible plates 31 on four sides can form a complete blocking surface, so that the rectangular shielding surface surrounded by the shielding flexible plates 31 can block the debris splashed during the column processing, limit the scope of the column processing to a smaller range, greatly reduce the scope of the column processing, reduce the overall footprint of the platform, and there is no need to worry about the phenomenon of debris splashing.

[0028] In order to facilitate the rotation and storage of the shielding flexible plate 31 so that it can better cooperate with the winding drum 32, the shielding flexible plate 31 adopts a plate-type structure, that is, the shielding flexible plate 31 includes a chain plate 311 wound on the winding drum 32, and a ring buckle 312 is locked on the top of the chain plate 311, and the ring buckle 312 is connected to the bottom of the connecting rope 33. A high-density net 313 is provided on the side of the chain plate 311 close to the column. The high-density net 313 is used to intercept iron filings. First, the ring buckle 312 is locked and fixed with the connecting rope 33, so that when the connecting rope 33 moves, it can drive the annular buckle 312 to move. However, if only the structure of the chain plate 311 is set, there will be a certain gap on the connecting end of the chain plate 311, and some debris will easily penetrate, and the iron filings themselves will cause wear to the chain plate 311. In this regard, the present embodiment further sets a high-density net 313 on the side of the chain plate 311 facing the column. The high-density net 313 is a flexible stainless steel structure, which can block the debris while protecting the chain plate 311.

[0029] In the process of cooperation between the shielding flexible plate 31 and the connecting cable 33, the connecting cable 33 needs to cross the gantry 11 to achieve the purpose of lifting and lowering the shielding flexible plate 31. However, if it is not guided, not only the connecting cable 33 is easy to break, but also the position of the shielding flexible plate 31 is easy to swing randomly. For this reason, a rib groove 13 is locked on the transverse part of the gantry 11, and the top of the rib groove 13 is open. The connecting cable 33 slides in the rib groove 13. The left and right ends of the rib groove 13 are chamfered, so that the position of the connecting cable 33 can be restricted and moved along a fixed route. In order to avoid breaking at the corner, a chamfer design is also made at the corner to reduce the pressure at the corner.

[0030] In order to allow the shielding flexible plate 31 to move straight up and down, a connecting rod 314 longer than the chain plate 311 extends from both ends of the annular buckle 312, and a longitudinal rail 14 is provided on the vertical part of the gantry 11 facing the side of the column. The connecting rod 314 is movably embedded in the longitudinal rail 14, and cooperates with the pulling force of the winding drum 32 and the connecting rope 33, so that the shielding flexible plate 31 can achieve a stable plane effect whether in the moving process or the fixed process.

[0031] After the shielding flexible plate 31 blocks the debris, some debris will adhere to the shielding flexible plate 31, thereby affecting the winding and recycling of the shielding flexible plate 31. In this regard, the present embodiment has a scraping structure based on the shielding flexible plate 31, and a one-way scraping arm 42 is arranged on the scraping structure. The one-way scraping arm 42 will only act on the shielding flexible plate 31 in the descending stage. After the shielding flexible plate 31 has played a role in a processing cycle, it needs to descend and be wound into the winding drum 32. During the descent, it will contact the one-way scraping arm 42, thereby scraping the debris on the shielding flexible plate 31 downwards. With the help of the natural force of the descent, the surface of the shielding flexible plate 31 can be made cleaner, and at the same time, it can prevent the phenomenon of debris damaging the surface and back of the shielding flexible plate 31 from occurring during the subsequent winding process.

[0032] The purpose of setting the one-way scraper arm 42 is to prevent iron filings from being generated during the rising process of the shielding flexible plate 31, and no scraping is required. In addition, setting one less scraping structure can reduce costs while reducing the replacement of wearing parts. The one-way scraper arm 42 is specifically configured as follows: the one-way scraper arm 42 includes a bending arm 421 connected to the inner side of the scraper frame 41, and a guide tool holder 422 is integrally formed on the bending arm 421. The guide tool holder 422 is tightly attached to the outer wall of the shielding flexible plate 31, and a scraper 423 with a blade pointing to the lateral part of the gantry 11 is mounted on the guide tool holder 422. The bending arm 421 can make the scraper 423 fit the shielding flexible plate 31 as closely as possible without causing damage to the shielding flexible plate 31, and the guide tool holder 422 movably installs the scraper 423 so that it can be replaced or maintained after long-term use.

[0033] Although the bending arm 421 allows the scraper 423 to be as close to the shielding flexible plate 31 as possible, in order to improve the fit and reduce the chance of damage to the shielding flexible plate 31, the bending arm 421 is bonded to the shielding flexible plate 31 through a rotating bonding structure 60. The rotating bonding structure 60 includes a fine-tuning motor 61 locked on the scraping frame 41. A rotating shaft 62 is clamped on the output shaft of the fine-tuning motor 61. The rotating shaft 62 is fixedly connected to the bending arm 421, and the rotating shaft 62 is provided on the inner wall of the scraping frame 41 through a clamping seat 63. The rotation design of the fine-tuning motor 61 allows the rotating shaft 62 to rotate in position, and then the rotating shaft 62 changes the position of the bending arm 421, so that the bending arm 421 drives the scraper 423 to change its position.

[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
