Abstract

Technical Field
[0001] This utility model relates to the field of machine tool auxiliary support technology, specifically an auxiliary support device for machine tool modification. Background Technology
[0002] Existing devices utilize support structures to support planes, cylinders, cones, and various curved surfaces. They have locking mechanisms to prevent threads from loosening or shifting due to part vibration. However, while providing support, they can also be installed on both sides simultaneously to reinforce the stability of the machine tool cutting tools. At the same time, the vibration frequency of the machine tool can be detected and counteracted, making the machine tool more stable. Furthermore, the detection sensors can accurately determine whether the vibration amplitude of the machine tool has been reduced, thus judging whether the machine tool can operate normally. Therefore, an auxiliary support device is needed to solve the above problems during machine tool modification. Utility Model Content

[0021] 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.
[0022] Please see Figure 1-5 An auxiliary support device for machine tool modification includes: a machining table 1, a support frame 2 connected to the bottom of the machining table 1, a triangular ground contact piece 3 fixedly connected to the outer wall of the support frame 2, a movable groove 4 formed in the inner wall of the machining table 1, a slide rod 5 provided in the inner wall of the movable groove 4, a slider 6 sleeved on the outer wall of the slide rod 5, a base 7 mounted on the top of the slider 6, a chuck motor 8 mounted on the top of the base 7, a clamping head 9 provided on the outer wall of the chuck motor 8, a base 10 mounted on the top of the slider 6, and a tool motor mounted on the top of the base 10. 11. A tool mounting base 12 is connected to the outer wall of the tool electromechanical device 11. A drill bit 13 is provided on the inner wall of the tool mounting base 12. A piezoelectric thin film sensor 14 is installed on the outer wall of the tool mounting base 12. A fixing frame 15 is connected to the outer wall of the base 10. An outer damping spring 16 is connected to the outer wall of the fixing frame 15. An inner damping spring 17 is connected to the outer wall of the fixing frame 15. A connector 18 is connected to the outer wall of the inner damping spring 17. A threaded head 19 is sleeved on the inner wall of the connector 18. A pressing rod 20 is sleeved on the inner wall of the connector 18.
[0023] Among them, the triangular ground contact piece 3 is set in a triangular shape, and four triangular ground contact pieces 3 are symmetrically arranged at the bottom of the processing table 1. By setting the triangular ground contact piece 3 on the device in a triangular shape, the triangular ground contact piece 3 on the device uses its own shape to stabilize the processing table 1 on the ground, and multiple triangular ground contact pieces 3 are connected to the ground.
[0024] There are two sliders 6, and the inner walls of the two sliders 6 are adapted to the size of the outer wall of the slide rod 5. Through the two sliders 6 on the device, the sliders 6 on the device are fitted onto the outer wall of the slide rod 5, and the sliders 6 move along the outer wall of the slide rod 5, thereby causing the sliders 6 on the device to drive the drill bit 13 and the clamp head 9 to move towards each other.
[0025] The clamp head 9 and the drill bit 13 are symmetrically arranged and are on the same horizontal line. By symmetrically arranging the clamp head 9 and the drill bit 13 on the device, the clamp head 9 on the device can clamp the object on the side away from the drill bit 13, and the drill bit 13 can be used to process the object, thereby enabling the device to process the object.
[0026] The outer wall of the tool mounting base 12 is provided with a conical surface, and the piezoelectric thin film sensor 14 is mounted on the conical surface. Because the outer wall of the tool mounting base 12 is provided with a conical surface, when the vibration force generated by the drill bit 13 in the cutting and modification operation is transmitted to the piezoelectric thin film sensor 14, the vibration signal is detected by the piezoelectric thin film sensor 14. After the vibration of the tool mounting base 12 puts pressure on the piezoelectric thin film sensor 14, the crystal element will generate a corresponding charge, and the charge number can be converted into vibration parameters.
[0027] The outer damping spring 16 and the inner damping spring 17 are connected to the fixing frame 15 and the connector 18 on both sides. The inner damping spring 17 is located inside the outer damping spring 16. Since the fixing frame 15 and the connector 18 are connected to both sides of the outer damping spring 16 and the inner damping spring 17, when the connector 18 is subjected to the vibration force transmitted from the tool mounting seat 12, the connector 18 on the device transmits the vibration force to the outer damping spring 16 and the inner damping spring 17, and then the outer damping spring 16 and the inner damping spring 17 cancel out the vibration force.
[0028] The inner wall of the connector 18 is provided with an internal thread, and the outer wall of the threaded head 19 is provided with an external thread. The internal thread on the inner wall of the connector 18 allows the threaded head 19 on the device to be threadedly connected to the connector 18. When the thread rotates, the threaded head 19 extends into the inner cavity of the connector 18 and pushes the extrusion rod 20 to extrude against the outer wall of the tool mounting seat 12.
[0029] Among them, a piezoelectric vibration sensor 21 is installed on the outer wall of the processing table 1, and the piezoelectric vibration sensor 21 faces and is attached to the outer wall of the base 10. By installing the piezoelectric vibration sensor 21 on the outer wall of the processing table 1, when the piezoelectric vibration sensor 21 is in close contact with the outer wall of the base 10, the vibration amplitude of the base 10 is sensed by the piezoelectric vibration sensor 21, thereby detecting the amplitude of the vibration force of the drill bit 13 reaching the bottom of the base 10 during cutting modification.
[0030] The working principle is as follows: First, by setting up an outer damping spring 16, an inner damping spring 17, a connector 18, and a pressing rod 20, the drill bit 13 on the device, when performing rotary cutting, uses the pressing rod 20 to abut against the outer wall of the tool mounting base 12 to transmit the vibration force to the connector 18. The outer damping spring 16 and the inner damping spring 17 perform double-spring damping operation, thereby gradually canceling out the vibration force transmitted from the drill bit 13. Then, by setting up a piezoelectric thin film sensor 14, a base 10, and a piezoelectric vibration sensor 21, the piezoelectric thin film sensor 14 is set on the outer wall of the tool mounting base 12, and the piezoelectric vibration sensor 21 is set close to the outer wall of the base 10. The piezoelectric thin film sensor 14 and the piezoelectric vibration sensor 21 detect two points respectively, thereby detecting the vibration amplitude at two points near and far from the drill bit 13, allowing the operator to fully understand the vibration impact of the drill bit 13.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
