Description

Technical Field

[0001] This utility model relates to the field of tool setting device technology, specifically an automatic tool setting device for precision parts machining. Background Technology

[0002] A tool setting device for a CNC machine tool is used to determine the relative position between the cutting tool and the workpiece. This device, through equipment such as a tool setter, achieves precise tool position measurement and adjustment to ensure that the cutting tool achieves the expected machining effect during use. The design and accuracy of the tool setting device have a significant impact on the machining accuracy and efficiency of the CNC machine tool. A tool setter, also known as a tool pre-setting device, is mainly used to accurately measure the geometric parameters of the cutting tool (such as length, diameter, and tool tip position) before or during CNC machining, and inputs this data into the CNC system to calibrate the relative position of the tool and the workpiece.

[0003] A patent search revealed an application with publication number "CN222154890U" titled "An Automatic Lifting Tool Setting Device." This document exposes the monitoring end of the tool setting device's top surface to the outside environment when not in use. In this state, dust, cutting fluid, oil, and other contaminants adhere to the monitoring end, affecting the accuracy of the tool setting measurement and consequently the precision of the automatic tool setting, ultimately leading to significant errors in the machined parts. Therefore, this invention designs an automatic tool setting device for precision parts machining to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tool setting device for precision parts machining, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tool setting device for precision parts machining, comprising a tool setting instrument, a base plate fixed to the bottom of the tool setting instrument, an electric push rod fixed to the top left of the base plate, a pull rod fixed to the top of the electric push rod, a rotating rod rotatably connected to the top of the pull rod, a protective component provided outside the rotating rod, the protective component including a connecting rod fixed to the top of the rotating rod, a sleeve provided at the end of the connecting rod away from the rotating rod, the sleeve being threaded onto the outside of the connecting rod, the sleeve being made of transparent material, and the sleeve having a tapered cross-section, a support plate fixedly fitted outside the pull rod, a motor fixedly fitted to the top left of the support plate, a drive gear fixedly fitted outside the output end of the motor, and a driven gear fixedly fitted outside the rotating rod.

[0006] Furthermore, the motor is a servo motor with a self-locking function. The motor stops running after rotating 180 degrees, and the driving gear and driven gear are designed to be meshed.

[0007] Furthermore, the size of the driving gear is the same as that of the driven gear, and mounting holes are integrally provided at the four corners inside the base plate. The mounting holes are through holes, and the base plate and the support plate are designed to be parallel to each other.

[0008] Furthermore, a guide plate is fixedly provided on the top left side of the base plate, and a guide hole is integrally provided inside the guide plate, with a sliding plate slidably connected inside the guide hole.

[0009] Furthermore, the top of the skateboard is fixedly connected to the bottom of the support plate, and the skateboard and the support plate are designed to be perpendicular to each other.

[0010] Furthermore, a top pin is fixed to the lower left side of the outer side of the skateboard. The top pin has a T-shaped cross-section and passes through the guide plate.

[0011] Furthermore, a clearance hole is integrally provided on the left side inside the guide plate. The clearance hole is a through hole design and is sleeved on the outside of the top pin.

[0012] Furthermore, a first limit switch is fixedly installed at the upper left end of the outer wall of the guide plate, and a second limit switch is fixedly installed at the lower left end of the outer wall of the guide plate, with the first limit switch and the second limit switch corresponding to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through its protective design, can isolate the monitoring end of the tool setter from the outside world when not in use, ensuring the cleanliness of the monitoring end. When the tool setter needs to be used, the sleeve can be misaligned with the monitoring end of the tool setter simply by using the electric push rod and motor, ensuring the accuracy of the tool setter for CNC machine tool tools.

[0015] 2. Through the design of the monitoring function, this utility model can control the distance of the sleeve's longitudinal displacement along the guide plate. This not only ensures the accuracy of the sleeve's separation from the tool setter's monitoring surface and prevents the rotating sleeve from colliding with the tool setter, but also ensures that when the sleeve is reset, the sleeve can completely cover the monitoring end of the tool setter, thus improving the stability of the sleeve's protection of the tool setter.

Detailed Implementation

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] like Figure 1 , Figure 2 , Figure 4 As shown, an automatic tool setting device for precision parts machining includes a tool setting instrument 1. A base plate 2 is fixedly mounted on the bottom of the tool setting instrument 1. An electric push rod 3 is fixedly mounted on the top left side of the base plate 2. A pull rod 4 is fixedly mounted on the top of the electric push rod 3. A rotating rod 5 is rotatably connected to the top of the pull rod 4. A protective component 6 is provided on the outside of the rotating rod 5. The protective component 6 includes a connecting rod 601 fixedly mounted on the top of the rotating rod 5. A sleeve 602 is provided at the end of the connecting rod 601 away from the rotating rod 5. The sleeve 602 is threaded onto the outside of the connecting rod 601. The sleeve 602 is made of transparent material and has a tapered cross-section. A support plate 603 is fixedly mounted on the outside of the pull rod 4. A motor 604 is fixedly mounted on the top left side of the support plate 603. A drive gear 605 is fixedly mounted on the outside of the output end of the motor 604. A driven gear 606 is fixedly mounted on the outside of the rotating rod 5.

[0025] The motor 604 is a servo motor with a self-locking function. The motor 604 stops running after rotating 180 degrees. The drive gear 605 and the driven gear 606 are designed to mesh. The size of the drive gear 605 is the same as that of the driven gear 606. The four corners of the base plate 2 are integrally provided with mounting holes 7, which are through holes. The base plate 2 and the support plate 603 are designed to be parallel to each other.

[0026] Before use, the operator first places the base plate 2 along with the tool setter 1 on one side of the CNC machine tool's worktable, then passes the bolts through the mounting holes 7 to securely connect the base plate 2 and the tool setter 1 to the CNC machine tool. The operator then connects the electric push rod 3, the motor 604, and the tool setter 1 to the CNC machine tool's control system via wires. During use, the sleeve 602 first covers the monitoring end on the top surface of the tool setter 1, isolating it from the outside environment. The operator then activates the electric push rod 3, which pushes the pull rod 4, causing the rotating rod 5, along with the connecting rod 601 and the sleeve 602, to move upwards along the longitudinal direction of the tool setter 1. Simultaneously, the pull rod 4 drives the support plate 603 and the motor 604 to move upward. This is to ensure the stability of the meshing between the drive gear 605 and the driven gear 606. The operator then turns on the motor 604, which drives the drive gear 605 to rotate the driven gear 606, along with the rotating rod 5, connecting rod 601, and sleeve 602, by 180 degrees before stopping. In this way, the sleeve 602 is completely misaligned with the monitoring end of the tool setter 1. At this time, the monitoring end of the tool setter 1 is clean. The operator then uses the CNC machine tool to enable the tool setter 1 to perform precise tool setting. Example 2

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a guide plate 8 is fixedly provided on the top left side of the base plate 2. A guide hole 9 is integrally provided inside the guide plate 8. A slide plate 10 is slidably connected inside the guide hole 9. The top of the slide plate 10 is fixedly connected to the bottom of the support plate 603. The slide plate 10 and the support plate 603 are designed to be perpendicular to each other. A top pin 11 is fixedly provided on the lower left side of the outer side of the slide plate 10. The top pin 11 has a T-shaped cross-section and passes through the guide plate 8. A clearance hole 12 is integrally provided on the left side of the inner side of the guide plate 8. The clearance hole 12 is a through hole and is fitted outside the top pin 11. A first limit switch 13 is fixedly provided on the upper left side of the outer wall of the guide plate 8. A second limit switch 14 is fixedly provided on the lower left side of the outer wall of the guide plate 8. The first limit switch 13 and the second limit switch 14 correspond to each other one by one.

[0028] According to the operation method in Embodiment 1, the operator can connect the first limit switch 13 and the second limit switch 14 to the control system of the CNC machine tool via wires. When the electric push rod 3 controls the pull rod 4 to move the support plate 603 upward, the support plate 603 moves the slide plate 10 along the direction of the guide hole 9. At the same time, the slide plate 10 moves the top pin 11 along the direction of the clearance hole 12 until the top pin 11 applies pressure to the first limit switch 13, at which point the electric push rod 3 stops operating. At this time, the bottom surface of the sleeve 602 is higher than the top surface of the monitoring end of the tool setter 1. When the operator turns on the motor 604, the rotating sleeve 602 prevents it from colliding with the tool setter 1. After the tool setting is completed, the operator turns on the motor 604 to rotate the sleeve 602 directly above the tool setter 1, and then turns on the pulling function of the electric push rod 3. That is, the electric push rod 3, the sleeve 602 and the top pin 11 are reset. When the top pin 11 applies pressure to the second limit switch 14, the electric push rod 3 stops running. At the same time, the sleeve 602 completely covers the monitoring end of the tool setter 1.
