Description

Technical Field

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

[0002] Automatic measuring devices for machining are measuring devices used in machining. Their core function is to automatically collect key parameters such as the size, shape, and position of the workpiece through preset measuring elements (such as laser measuring heads, sensors, etc.) before the workpiece is processed, and to feed the data back to the control system in real time, so as to achieve precise control, error correction or quality inspection of the machining process, and ultimately improve machining accuracy and efficiency while reducing manual intervention.

[0003] A search revealed Chinese patent application CN202020763151.3, which discloses a machining device with automatic detection function. The device includes a frame, a worktable, a drive mechanism, a clamping mechanism, and a measuring mechanism. The worktable is mounted on the frame, and the clamping mechanism is mounted on the worktable for centering and clamping the workpiece. The drive mechanism is fixed to the bottom of the worktable to drive the clamping mechanism in clamping and releasing actions. The measuring mechanism is mounted on the clamping mechanism to measure the workpiece clamped therein. The drive mechanism includes a motor and a rotating shaft. The motor is fixedly mounted on the bottom of the worktable, and the rotating shaft is directly or indirectly connected to the output shaft of the motor. This machining device with automatic detection function, through the measuring mechanism mounted on the clamping mechanism, can automatically measure the length of the workpiece after it is clamped and fixed, thereby facilitating the adjustment of the position of the machining mechanism and achieving high machining accuracy and efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: While the existing technologies can automatically measure the length of a workpiece through a measuring mechanism, thereby improving processing accuracy and efficiency, in actual use, dust is generated during subsequent cutting processes after the measuring mechanism measures the workpiece. The dust particles directly obstruct the laser emitter and laser receiver in the measuring mechanism, affecting the subsequent measurement accuracy. Therefore, it is necessary to design an automatic measuring device for machining that is both practical and has protective functions. Utility Model Content

[0015] 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.

[0016] Please see Figure 1-5The present invention provides a technical solution: an automatic measuring device for machining, including a machining table 1, two sliding grooves 2 are opened on the upper side of the machining table 1, and a take-up block 3 is slidably fitted on the inner wall of each of the two sliding grooves 2. An empty groove block 4 is fixedly connected to the upper side of each of the two take-up blocks 3, and a laser measuring head 5 is fixedly connected to the upper side of each of the two empty groove blocks 4. The inner walls of the two empty slot blocks 4 are slidably fitted with protective blocks 6. A tension spring 7 is fixedly connected between the protective blocks 6 and the empty slot blocks 4. The lower side of the inner wall of the empty slot blocks 4 is provided with a starting component 8 that cooperates with the laser measuring head 5. A triggering mechanism 9 is provided on the adjacent side of the empty slot blocks 4. A processing mechanism 10 is provided on the upper side of the processing table 1. A bidirectional lead screw 11 is rotatably fitted to the inner walls of the two sliding slots 2.

[0017] Please see Figure 3 The starting component 8 includes a movable groove 801 formed on the lower side of the inner wall of two empty slot blocks 4, a trigger block 802 slidably engaged with the inner wall of the two movable grooves 801, a trigger switch 803 fixedly connected to the trigger block 802 and electrically engaged with the laser measuring head 5, and a force spring 804 fixedly connected between the trigger block 802 and the movable groove 801. When the trigger block 802 slides in the movable groove 801 under external force, it will compress or release the force spring 804, and at the same time drive the trigger switch 803 fixed on it to move synchronously. When the trigger switch 803 is triggered, it forms an electrical linkage with the laser measuring head 5 to realize the start or stop of the laser measuring head 5. The elastic action of the force spring 804 can reset the trigger block 802 and the trigger switch 803 when there is no external force.

[0018] Please see Figure 3 The triggering mechanism 9 includes two guide rods 901 that slide together on the adjacent side of the two empty slot blocks 4, a tightening block 902 fixedly connected to one end of the two guide rods 901, a push plate 903 fixedly connected to the other end of the two guide rods 901 and cooperating with the trigger block 802, and a reset spring 904 fixedly connected between the tightening block 902 and the empty slot block 4. When the workpiece contacts the tightening block 902 and pressure is applied, the tightening block 902 drives the guide rods 901 to slide into the empty slot block 4, while compressing the reset spring 904. At the same time, the push plate 903 at the other end of the guide rod 901 moves with it and interacts with the trigger block 802. When the workpiece is removed, the elastic force of the reset spring 904 pushes the tightening block 902 to reset, thereby driving the guide rods 901 and the push plate 903 back to their initial positions, realizing the automatic reset of the triggering action.

[0019] Please see Figure 5The processing mechanism 10 includes a U-shaped frame 101 fixedly connected to the upper side of the processing table 1, a multi-directional slide rail 102 fixedly connected to the upper side of the inner wall of the U-shaped frame 101, an electric push rod 103 set on the multi-directional slide rail 102, and a processing equipment body 104 fixedly connected to the electric push rod 103. The U-shaped frame 101 provides fixed support for the entire mechanism. The multi-directional slide rail 102 can drive the electric push rod 103 and the processing equipment body 104 on it to move in multiple directions. The electric push rod 103 can drive the processing equipment body 104 to adjust up and down. Through the movement adjustment of the multi-directional slide rail 102 and the lifting of the electric push rod 103, the processing equipment body 104 can be adjusted to a suitable position in three-dimensional space, thereby performing precise processing operations on the workpiece.

[0020] Please see Figure 3 and Figure 4 Two limiting blocks 12 are fixedly connected to the adjacent side of the two trigger blocks 802. The two limiting blocks 12 cooperate with the trigger switch 803. When the push plate 903 pushes the trigger switch 803, the limiting blocks 12 can limit the maximum pressure on the trigger switch 803, so as to avoid damage to the trigger switch 803 during the pushing process.

[0021] Please see Figure 5 One end of the bidirectional lead screw 11 extends to one side of the processing table 1 and is rotatably engaged. One end of the bidirectional lead screw 11 is fixedly connected to a knob 13. By rotating the knob 13 on one side of the processing table 1, the bidirectional lead screw 11 is driven to rotate on the inner wall of the two sliding grooves 2. Utilizing the thread transmission characteristics of the bidirectional lead screw 11, the two take-up and release blocks 3 are driven to slide synchronously in opposite directions along the sliding grooves 2, thereby realizing the adjustment of the distance between the empty groove block 4 and the laser measuring head 5 to adapt to the measurement needs of workpieces of different sizes.

[0022] Please see Figure 3 The lower sides of both protective blocks 6 are inclined, and the upper sides of both trigger blocks 802 are provided with lubrication grooves 14. The inner walls of both lubrication grooves 14 are rotatably fitted with lubrication wheels 15 that cooperate with the two protective blocks 6. The inclined design of the lower side of the protective block 6 allows it to convert the horizontal sliding of the trigger block 802 into the vertical lifting and lowering motion of the protective block 6 when it comes into contact with the lubrication wheel 15 in the lubrication groove 14 on the upper side of the trigger block 802. At the same time, the rotation of the lubrication wheel 15 in the lubrication groove 14 greatly reduces the sliding friction resistance between the protective block 6 and the trigger block 802, ensuring that the protective block 6 can smoothly rise and fall with the movement of the trigger block 802, which not only ensures the timely response of the protective function, but also reduces component wear and extends service life.

[0023] The implementation principle of this application is as follows: When using this device, firstly, the workpiece to be processed is placed on the upper side of the processing table 1. Then, by rotating the bidirectional lead screw 11, the two take-up and release blocks 3 are driven to move in similar directions. The movement of the take-up and release blocks 3 drives the two empty slot blocks 4 to move synchronously. During the movement, the tightening block 902 will contact both sides of the workpiece. During the tightening of the workpiece, the return spring 904 will retract accordingly. The guide rod 901 pushes the push plate 903 to move towards the trigger block 802. First, it will contact the trigger switch 803. When the contact is made, the trigger switch 803 is pressed, which opens the two laser measuring heads 5. One of the two laser measuring heads 5 is the transmitting end and the other is the receiving end, which can realize automatic length detection. The elastic force of the reset spring 904 is relatively weak, while the strength of the force spring 804 is higher than that of the reset spring 904. When the tightening block 902 contacts and tightens with the workpiece, due to the action of the force spring 804, the two push plates 903 will be squeezed against the two corresponding trigger switches 803, and then squeeze the two force springs 804 respectively for subsequent movement. After the distance detection is completed, the push plate 903 will continue to tighten and squeeze the trigger block 802. The trigger block 802 will squeeze the bottom of the protective block 6. After being squeezed, the protective block 6 will move upward inside the empty slot block 4, thereby protecting one side of the laser measuring head 5. This can reduce the corrosion of the laser measuring head 5 by dust in subsequent processing, thus maintaining the accuracy of subsequent measurements.
