Description

Technical Field

[0001] This utility model belongs to the field of CNC machining equipment technology, specifically relating to a machining center with a tool setter. Background Technology

[0002] In CNC machine tool machining, tool positioning is a crucial step to ensure machining accuracy. Typically, this process requires a specialized tool setter for precise positioning. However, existing tool setting technologies have some significant drawbacks, which to some extent affect machining efficiency and tool lifespan.

[0003] Firstly, regarding the issue of residual debris, we found that metal shavings or cutting fluid residue often accumulate on the surface of the tool block. The presence of these residues can cause micron-level errors at the tool contact surface, which is unacceptable for high-precision CNC machining. Therefore, operators have to frequently stop the machine for manual cleaning, which not only increases workload but also reduces production efficiency.

[0004] Secondly, traditional tool setting devices lack real-time cleaning capabilities. They typically rely on physical scraping or manual cleaning with an air gun, methods that cannot automatically remove tool debris before the tool contacts the tool setting block. This means that even after cleaning, the tool may still be affected by residual debris when it contacts the tool setting block, thus impacting machining accuracy.

[0005] Finally, regarding the inadequacy of protective performance, the existing open-face tool setting structure is susceptible to secondary contamination from external debris. This contamination not only affects the positioning accuracy of the tool but may also negatively impact the service life of the tool setter. Due to the lack of effective protective measures, debris and cutting fluid can easily enter the tool setter, increasing the difficulty and cost of equipment maintenance.

[0006] In view of the above-mentioned technical defects, this utility model proposes a new technical innovation solution to solve them. Utility Model Content

[0007] The purpose of this invention is to provide a machining center with a tool setter, which solves the problems mentioned in the background art, such as the presence of residual debris on the surface of the tool setter affecting the tool setting accuracy, the inability to automatically clean debris from the surface of the tool setter, and the tool setter being easily damaged due to contamination.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a machining center with a tool setter, comprising: a machining center and a tool setter body, the tool setter body being disposed on the worktable of the machining center, the outer side of the tool setter body being covered with a protective shell, the outer layer of the protective shell being provided with an annular guide groove in the circumferential direction, the bottom of the protective shell being provided with a chip discharge port, and multiple sets of nozzles being evenly distributed on the inner side of the guide groove, the nozzles being connected to an external high-pressure source through a guide pipe.

[0009] Furthermore, the nozzles are in two sets, located at the two inner corners above the protective housing, with the nozzles pointing downwards and towards the center of the tool block surface.

[0010] Furthermore, it also includes a control module, which includes a sensor for sensing the tool position and a PLC controller. The sensor is located on the tool setting device body, and the detection direction of the sensor is towards the end face of the tool. The sensor is connected to the PLC controller. A pipeline switch valve is connected in series on the guide pipe, and the PLC controller is connected to the pipeline switch valve.

[0011] Furthermore, the upper part of the protective shell is provided with a hollow cavity with a hollow structure. The hollow cavity has an inlet and an outlet. The outlet is connected to a nozzle, and the inlet is connected to an external high-pressure source.

[0012] Furthermore, the hollow cavity includes two independent first chambers and second chambers. The first chamber has a first inlet and a first outlet, and the second chamber has a second inlet and a second outlet. The first inlet and the second inlet are respectively connected to an external high-pressure gas source and a high-pressure liquid source, and the first outlet and the second outlet are respectively connected to a gas nozzle and a liquid nozzle.

[0013] Furthermore, the first chamber and the second chamber are arranged side by side above the tool setting block along the direction of movement of the tool setting block, the first outlet and the second outlet are distributed on the left and right sides of the tool setting block, and the spray direction of the gas nozzle and the liquid nozzle is towards the center of the surface of the tool setting block.

[0014] Furthermore, the chip discharge port is connected to a negative pressure dust collection device via a dust collection pipe, and the negative pressure dust collection device's start / stop switch is connected to the PLC controller.

[0015] Furthermore, the spray axis of the nozzle forms an angle of 40°-50° with the surface of the tool setting block, and the nozzle diameter is 3-12mm.

[0016] Furthermore, the nozzle has a diameter of 5 mm.

[0017] Furthermore, the guide pipe is connected in series with a pressure regulating valve for adjusting the injection pressure, and the pressure regulating valve can adjust the injection pressure range to 0.4-0.6 MPa.

[0018] Compared to related technologies, the advantages of this application are as follows: This application provides a machining center with a tool setter. The tool setter is installed on the worktable of the machining center and is equipped with nozzles that automatically blow away residual materials. Operators do not need to frequently stop the machine for manual cleaning, thus improving work efficiency. In addition, it can automatically remove debris from the tool before the tool contacts the tool setter block, ensuring that the accuracy of tool setting is not affected by debris on the tool's surface. Furthermore, because a protective shell for protecting the user from debris is added, the tool setter can be protected and its lifespan extended. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 5 This utility model discloses a machining center with a tool setter, comprising a machining center and a tool setter body 1. The tool setter body 1 is mounted on the worktable 2 of the machining center. A protective shell 3 covers the outer side of the tool setter body 1. The outer layer of the protective shell 3 has an annular guide groove on its outer circumference. A chip discharge port 30 is opened at the bottom of the protective shell 3. Multiple sets of nozzles 4 are evenly distributed inside the guide groove. The nozzles 4 are connected to an external high-pressure source 5 through guide pipes 45. Each tool setter body 1 contains a tool setter block 12, which is used to engage with a tool 7 in one direction for tool setting. When the machining center includes multiple tools 7, multiple tool setter bodies 1 can be provided, each tool setter body 1 corresponding to and engaging with a tool 7 in one direction for tool setting. The external high-pressure source is usually a high-pressure air source or a high-pressure liquid source. The high-pressure liquid source is usually a rust-preventive cutting fluid or an environmentally friendly cutting fluid. Compared with the elegant airflow, the high-pressure liquid flow usually has a better flushing effect and a greater impact force, which can better flush away residual debris and keep the surface of the tool block 12 clean.

[0029] In one embodiment, there are two sets of nozzles 4, which are located at the two bends on the inner side of the upper part of the protective housing 3. The nozzles of the two sets of nozzles 4 are downward and directed toward the center of the surface of the tool setting block 12, so as to blow away the residual debris at the contact position between the surface of the tool setting block 12 and the tool 7. The two nozzles 4 correspond to the same position on the surface of the tool setting block 12. This dual chip blowing mode has a better cleaning effect, so the chip removal effect is better and the cleaning is more thorough.

[0030] In one embodiment, the present invention further includes a control module 6, which includes a sensor 61 and a PLC controller 62. The sensor 61 is mounted on the tool setting device body 1, and the detection direction of the sensor 61 is towards the end face of the tool 7. The sensor 61 is connected to the PLC controller 62. A pipeline switching valve 49 is connected in series on the guide pipe 45, and the PLC controller 62 is connected to the pipeline switching valve 49. The sensor 61 is used to sense whether the tool 7 is approaching the tool setting block 12, and to trigger the spraying action when the tool 7 approaches the tool setting block 12. When the tool 7 approaches the tool setting block 12 to a predetermined position range, the pipeline opening is activated by the PLC controller 62. When valve 49 is closed, nozzle 4 sprays high-pressure gas or liquid toward the outer end face of tool 7 to clean the debris on the surface of tool 7. This prevents tool setting errors caused by residue on the surface of tool 7 during tool setting, which would lead to relative coordinate errors and consequently, errors in the machining depth of the product. This avoids quality problems in product processing. Sensor 61 can be an infrared radar, but it is best to use a laser radar with a shorter wavelength, which has higher accuracy to improve the detection effect of tool 7. Typically, control module 6 is configured to activate the pipeline switch valve to spray the end face of tool 7 for 0.5-0.8 seconds after detecting that tool 7 has entered a sensing range of 10-16mm, and then stop.

[0031] In one embodiment, a negative pressure dust collection device is also included. The negative pressure dust collection device is connected to the chip discharge port through a dust collection pipe. The negative pressure dust collection start / stop switch 9 of the negative pressure dust collection device is connected to the PLC controller 62. When the pipeline switch valve is opened to remove chips from the tool, the negative pressure dust collection device will also be turned on at the same time. It can promptly suck away the waste chips washed down through the dust collection pipe, preventing the blown-down chips from floating inside the protective shell 3 or accumulating at the chip discharge port at the bottom of the protective shell 3, which would cause secondary pollution to the surface of the tool block 12 during subsequent frequent rinsing.

[0032] In one embodiment, the upper part of the protective housing 3 is provided with a hollow structure, the hollow structure has an inlet and an outlet, the outlet is connected to the nozzle 4, and the inlet is connected to an external high-pressure source.

[0033] Furthermore, the hollow structure includes two independent chambers, a first chamber 31 and a second chamber 32. The first chamber 31 has a first inlet and a first outlet, and the second chamber 32 has a second inlet and a second outlet. The first inlet and the second inlet are respectively connected to an external high-pressure air source and a high-pressure liquid source, and the first outlet and the second outlet are respectively connected to a gas nozzle and a liquid nozzle. The first chamber 31 and the second chamber 32 are arranged side by side above the tool setting block along the direction of movement of the tool setting block. The first outlet and the second outlet are distributed on the left and right sides of the tool setting block 2, and the spray direction of the gas nozzle and the liquid nozzle is towards the center of the surface of the tool setting block 2.

[0034] In one embodiment, the spray axis of nozzle 4 forms an angle of 40°-50° with the surface of the tool setting block 2. The nozzle diameter is typically 3-12mm, with 5mm being a common diameter. A pressure regulating valve is also provided inside the guide tube 45, which can adjust the spray pressure range to 0.4-0.6MPa.

[0035] In one embodiment, the PLC controller 62 has a cleaning cycle memory function, which can store the parameters of the most recent 1000 sprays, including an audible and visual alarm. The system can select to turn the "audible and visual alarm" function on or off. When the system selects the "audible and visual alarm" function to be on, if the sensor still detects debris on the surface of the blade block after 3 consecutive sprays, the alarm will be triggered and the machine will automatically stop and wait for manual handling. After the manual handling is completed, the equipment can continue to run after the manual presses the "continue" button.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
