Description

Technical Field

[0001] This utility model relates to the technical field of V-groove processing equipment, specifically to a V-groove machine tool holder position adjustment mechanism. Background Technology

[0002] V-groove machines are specialized equipment used to cut V-shaped grooves in cardboard, grey board, MDF, and other sheet materials. They are widely used in the production of packaging boxes, gift boxes, and other products. In existing technology, the cutter holder of a V-groove machine is typically fixed to the cutter head with screws or other fasteners. When the cutter holder position needs to be adjusted to accommodate new product specifications or for equipment maintenance, the operator must first loosen these fixing screws and then move the cutter holder to the target position. Determining the cutter holder position often relies on manual measurement by the operator using measuring tools such as vernier calipers.

[0003] Because it relies on manual operation and measurement, the adjustment of the tool holder position is often difficult to be accurate in one go. It may require repeated fine-tuning and measurement, which reduces production efficiency. Furthermore, the error of manual measurement may also cause the final V-groove size to not meet the preset standard, affecting product quality and even causing the risk of batch products being unqualified. Utility Model Content

[0049] Example 1

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a V-groove machine tool holder position adjustment mechanism includes: a mounting base plate 1 and at least one set of tool holder assemblies 2.

[0051] Mounting base plate 1 is directly mounted on the V-groove machine, serving as the foundation component of the entire adjustment mechanism. All other components are directly or indirectly mounted and fixed on this base plate.

[0052] The tool holder assembly 2 is the core module for adjusting the tool position. In this embodiment, there can be one or more such tool holder assemblies 2. Each tool holder assembly 2 is mounted on the mounting base plate 1, and the specific position is determined according to the actual situation. Each tool holder assembly 2 has the ability to independently adjust its tool holder position, and the structure of each tool holder assembly 2 is the same, including:

[0053] At least one tool holder, which is a component that directly clamps V-groove tools and allows for tool replacement as needed.

[0054] The tool holder mounting base 5 is a movable platform that supports the tool holder, which is mounted on the tool holder mounting base 5.

[0055] The drive unit is used to drive the tool holder mounting base 5 to move along a preset path. Through the action of the drive unit, the tool holder moves to the designated working position along with its mounting base.

[0056] The displacement sensing device is used to detect the moving distance of the tool holder mounting base 5. It can detect and quantify the actual displacement distance or current position of the tool holder mounting base 5 during the moving process in real time.

[0057] The control system is connected to the drive unit and the displacement sensing device. The control system is used to control the drive unit to move according to preset instructions and to control the drive unit to stop according to the detection results of the displacement sensing device.

[0058] The function of the control system is to receive preset commands from external input (e.g., a target position set by the operator). Based on these commands, it sends control signals to the drive unit, causing it to start and move the tool holder mounting base 5. Simultaneously, it continuously receives feedback signals from the displacement sensor. When the control system determines (based on the feedback from the displacement sensor) that the tool holder mounting base 5 has reached the target position specified by the preset command, it sends another control signal to stop the drive unit.

[0059] The control system includes a human-machine interface (HMI) for operators to input control commands for the drive device. Distance can be controlled intuitively through the HMI without requiring specialized knowledge.

[0060] Example 2

[0061] This embodiment, based on Embodiment 1, describes the specific structure of the driving device and the guiding method of the tool holder mounting base 5.

[0062] The drive unit includes:

[0063] The servo motor 6, which serves as the power source, receives instructions from the control system and performs rotational motion according to the instructions.

[0064] The lead screw 7 is connected to the output end of the servo motor 6. When the servo motor 6 rotates, the lead screw 7 rotates synchronously.

[0065] The lead screw connector 8 is threaded with the lead screw 7 and is connected to the tool holder mounting base 5 so that when the servo motor 6 drives the lead screw 7 to rotate, it can move the tool holder mounting base 5.

[0066] When the servo motor 6 drives the lead screw 7 to rotate, the lead screw connector 8 engages with the lead screw 7 through threaded engagement, causing the lead screw 7 to rotate and move along the axial direction (i.e., the linear direction) of the lead screw 7. Simultaneously, the lead screw connector 8 is connected to the tool holder mounting base 5, enabling the linear translation of the tool holder mounting base 5.

[0067] The regulating mechanism also includes:

[0068] The main guide rail 9 is set on the mounting base plate 1;

[0069] The main slider 10, which slides in conjunction with the main guide rail 9, can slide along the length of the main guide rail 9.

[0070] The tool holder mounting base 5 is mounted on the main slider 10, and the main guide rail 9 limits the preset path for the movement of the tool holder mounting base 5. The tool holder mounting base 5 can only move along the direction determined by the main guide rail 9, which ensures the linearity and stability of its movement and prevents deviation or shaking during movement.

[0071] The control system sends rotation commands (including rotation angle, speed, etc.) to the servo motor 6.

[0072] The servo motor 6 rotates, driving the lead screw 7 connected to it to rotate synchronously.

[0073] The rotation of the lead screw 7 is converted into the linear motion of the lead screw connector 8 through the lead screw connector 8 that is threaded with it.

[0074] Since the lead screw connector 8 is connected to the tool holder mounting base 5, the tool holder mounting base 5 will produce the same linear displacement.

[0075] Example 3

[0076] The displacement sensing device includes a reading head housing 11 that moves synchronously with the lead screw connector 8. A reading head is installed within the reading head housing 11 for counting the movement distance of the tool holder mounting base 5. The reading head is a precision sensing element for displacement counting, configured to accurately measure and count the movement distance of the tool holder mounting base 5. Typically, the reading head is used in conjunction with a fixedly mounted scale or ruler (in this embodiment, the scale is adjusted to 0.01 mm) to jointly complete the distance measurement.

[0077] A profile groove 12 for mounting the reading head housing 11 is provided on one side of the mounting base plate 1. The reading head housing 11 slides in the profile groove 12, and the sliding path is parallel to the preset path.

[0078] The preset path refers to the path along which the tool holder mounting base 5 moves on the main guide rail 9. The sliding path of the reading head housing 11 is parallel to the moving path of the tool holder mounting base 5, ensuring that the displacement measured by the reading head can accurately and proportionally correspond to the actual linear displacement of the tool holder mounting base 5, thus avoiding measurement errors caused by factors such as angular deviation.

[0079] Example 4

[0080] Based on actual needs, the tool holder mounting base 5 supports at least two tool holders, including:

[0081] A fixed tool holder 3 is fixed to the tool holder mounting base 5;

[0082] At least one movable tool holder 4 is provided, which is movably connected to the tool holder mounting base 5 via a moving device. The distance between the two tool holders is the V-groove spacing.

[0083] The moving device includes a secondary guide rail 13 disposed on the tool holder mounting base 5 and a secondary slider 14 that slides with the secondary guide rail 13; wherein, the moving tool holder 4 is mounted on the secondary slider 14, and the secondary guide rail 13 defines the moving path of the moving tool holder 4.

[0084] The moving device also includes a fine-tuning device for driving the moving tool holder 4 to move along its moving path. The fine-tuning device includes a fine-tuning motor 15, a fine-tuning screw 7, and a fine-tuning connector. The fine-tuning connector is threadedly engaged with the fine-tuning screw 7. The output end of the fine-tuning motor 15 is connected to the fine-tuning screw 7. The moving tool holder 4 is fixedly connected to the fine-tuning connector.

[0085] The main adjustment system (as in Examples 1 to 3) is responsible for the overall and large-scale automatic positioning of the tool holder mounting base 5; while one or more moving devices installed on the tool holder mounting base 5 are responsible for the local, precise and independent fine-tuning of their respective moving tool holders 4.

[0086] The working principle and process can be understood as follows:

[0087] Main positioning: The control system drives the main drive unit (servo motor 6, lead screw 7, and lead screw connector 8) to move the entire tool holder mounting base 5 (including the fixed tool holder 3 and the movable tool holder 4) along the main guide rail 9 to the preset global working area. This process is monitored by the main displacement sensor.

[0088] Secondary fine-tuning: After the main tool holder mounting base 5 is positioned (or during initial setup), the operator or control system can independently control the fine-tuning device of each moving tool holder 4.

[0089] The control signal drives a specific fine-tuning motor 15 to rotate, which in turn drives the fine-tuning screw 7 to rotate. The fine-tuning screw 7 drives the corresponding movable tool holder 4 (mounted on the secondary slider 14) to move linearly within a small range and with high precision along the secondary guide rail 13 fixed on the main tool holder mounting base 5 through the fine-tuning connector.

[0090] V-groove spacing adjustment: By making the above-mentioned independent fine adjustments to one or more movable tool holders 4, their relative positions with the fixed tool holder 3 or with each other can be precisely adjusted, thereby achieving precise setting and adjustment of the V-groove machining spacing.
