Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a built-in detection device. Background Technology

[0002] With the rapid development of the machine tool industry at home and abroad, the complexity and size of production and processing equipment are constantly changing, and the requirements for the processing accuracy of machine tools are also getting higher and higher. Therefore, detection devices are installed in machine tools to measure the dimensions of the workpieces being processed, so that defective workpieces can be reprocessed in a timely manner.

[0003] Existing detection devices, such as the contact-type unidirectional measuring device disclosed in Chinese patent literature [Patent No.: 202120553197.7; Application Publication No.: CN215035934U], consist of a support plate, an adapter plate, a guide rail, a slider, a sliding body, a pneumatic drive device, and a contact probe. The support plate is mounted on the Z-axis moving assembly of the machine tool via the adapter plate and can move up and down under the action of the Z-axis drive device. The guide rail and the pneumatic drive device are both mounted on the support plate. The sliding body acts on the guide rail via the slider and can move up and down along the guide rail under the action of the pneumatic drive device. The contact probe is mounted on the lower end of the sliding body and can move up and down with the sliding body. The contact probe is connected to the machine tool control device via a signal line to transmit the measurement signal to the machine tool CNC system.

[0004] In this type of measuring device, when the machine tool is machining a workpiece, the cylinder is in the retracted state, and the contact probe is in its highest position, without affecting the normal machining process. When the machine tool stops machining, the cylinder extends, and the contact probe moves downward along the guide rail to its designated position to measure the workpiece dimensions. However, this type of measuring device has several drawbacks. During machining, the machine tool generates flying debris, and coolant also splashes. This flying debris can collide with and damage the contact probe, while debris and coolant can adhere to the contact probe, further damaging it. Ultimately, this reduces the accuracy of the measuring device. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a built-in detection device, which solves the technical problem of how to make the detection device less prone to damage.

[0006] The objective of this invention can be achieved through the following technical solution: a built-in detection device, including a mounting base, on which a detector is disposed, characterized in that a first driver is fixedly connected to the mounting base and inclined downwards, a protective cover is fixedly connected to the output shaft of the first driver, and the side of the protective cover has a clearance hole for the probe of the detector to pass through, and the first driver drives the protective cover to move obliquely so that the protective cover covers the probe of the detector or moves away from the probe of the detector.

[0007] When a machine tool processes a workpiece, the detector probe is used to inspect the workpiece. A protective cover is placed over the detector probe to prevent debris and coolant from splashing onto it, thus minimizing damage to the inspection device. After workpiece processing is complete, the cutting tool and coolant stop operating. The first actuator moves the protective cover away from the detector probe, exposing it for workpiece inspection. After inspection, the first actuator moves the protective cover, allowing the detector probe to pass through a clearance hole and finally cover the probe. Then, the workpiece can be further processed or the next workpiece can be processed. The clearance hole prevents the protective cover from contacting the detector probe, allowing the cover to move and cover it with relatively small movement and minimal space occupation. During operation, some debris and coolant will inevitably splash and adhere to the protective cover, and some debris and coolant will also fall onto the first driver. The first driver is set at an angle downwards. When the first driver drives the output shaft and the protective cover to move at an angle downwards or upwards, a certain amount of vibration is generated. This vibration, combined with the gravity and inertia of the debris and coolant themselves, can shake the debris and coolant off the angled first driver and the angled protective cover, preventing the accumulation of debris and coolant on the protective cover and the first driver. This also prevents the debris and coolant adhering to the protective cover and the first driver from falling onto the detector probe, making the detection device less prone to damage.

[0008] In the aforementioned built-in detection device, the protective cover includes a cylindrical protective section at the top, which is closed at the top and penetrates at the bottom. The protective section is vertically oriented, and a clearance hole is located in the side wall of the protective section. This clearance hole is elongated and its bottom penetrates the protective cover. This detection device is located below the workpiece during processing. This clearance hole structure ensures that the protective cover and the detector probe will not come into contact. Simultaneously, the cylindrical shape and vertical orientation of the protective section prevent debris and coolant from easily entering the protective cover through the clearance hole on the side, ensuring the protective isolation effect of the protective cover and making the detection device less prone to damage.

[0009] In the aforementioned built-in detection device, the protective cover includes a connecting portion fixedly connected to the bottom of the protective part. The connecting portion protrudes circumferentially relative to the protective part and is fixedly connected to the output shaft of the first driver. The connecting portion serves as a connecting carrier. Its protruding and relatively thick shape enhances the firmness of the connection between the protective cover and the output shaft of the first driver, improves the stability of the protective cover, ensures its protective isolation effect, and makes the detection device less prone to damage.

[0010] In the aforementioned built-in detection device, the side of the protective part also has a vent hole, which is arranged opposite to the clearance hole. An air blowing pipe is fixedly connected to the mounting base, with the air outlet of the air blowing pipe facing both the clearance hole and the vent hole. When needed, the air blowing pipe can be opened, and the gas blown out by the air blowing pipe enters the protective cover through the clearance hole, blowing air onto the probe of the detector located within the protective cover. This blows away debris and coolant adhering to the probe. Because the vent hole and clearance hole are arranged opposite each other, debris and coolant blown off the probe of the detector are blown out through the vent hole and will not fall into the protective cover, thus preventing re-contamination of the detector and ensuring the stability of the detector test, making the detection device less prone to damage. The vent hole is also located on the side of the protective part, which is arranged vertically; therefore, debris and coolant are less likely to enter the protective cover through the vent hole.

[0011] In the aforementioned built-in detection device, the vent is elongated, and both the vent and the clearance hole are vertically oriented. The tops of the vent and the clearance hole are flush, and the outlet of the air-blowing pipe faces the tops of both the clearance hole and the vent. This structure ensures that debris and coolant blown off the detector's probe are expelled through the vent and do not fall into the protective cover, thus preventing re-contamination of the detector and ensuring the stability of the detector's testing, making the detection device less prone to damage.

[0012] In the aforementioned built-in detection device, a guide plate is fixedly connected to the mounting base. The guide plate has an elongated guide groove, and the air blowing tube is a shape-memory flexible tube that passes through the guide groove. The guide groove guides the air blowing tube, and the shape-memory flexible tube can be adjusted as needed. The air blowing tube can be used to clean the probes of the detector, as well as to clean the protective cover and other structures within the detection device, ensuring the cleanliness of the device and preventing damage.

[0013] In the aforementioned built-in detection device, a second driver and a slide rail are fixedly connected to the mounting base. A slider is slidably connected to the slide rail. The second driver drives the slider to move along the slide rail. The slider has a recessed clearance notch. The main body of the detector is located in the clearance notch, and the detector is fixedly connected to the slider. After the first driver drives the protective cover away from the detector, the second driver can drive the slider to move along the slide rail, that is, drive the detector to move along the slide rail, allowing the detector to extend, increasing the detection stroke, and allowing the detection device to move away from the workpiece, reducing the probability of debris and coolant falling onto the protective cover and detector, and making the detection device less prone to damage.

[0014] In the aforementioned built-in detection device, both the slide rail and the slider are arranged vertically. A dustproof plate is fixedly connected to the mounting base, located above the slide rail. The dustproof plate has a dustproof section made of rubber material along its edge, which is flush with the slider. The dustproof plate and dustproof section serve to block debris and coolant, preventing them from falling onto the slide rail, ensuring the detector can move into position, and minimizing the risk of damage to the detection device.

[0015] In the aforementioned built-in detection device, the protective structure further includes a first protective shell and a second protective shell respectively fixed to both sides of the mounting base. The first driver is located in the first protective shell, and the second driver is located in the second protective shell. The slide rail and the slider are both located between the first and second protective shells. The first protective shell protects the first driver, and the second protective shell protects the second driver, making the first and second drivers less susceptible to damage, and thus the detection device less susceptible to damage. The slide rail and the slider are both located between the first and second protective shells, making efficient use of space, resulting in a compact detection device structure that occupies little space and reducing the surface area for debris and coolant adhesion.

[0016] In the aforementioned built-in detection device, the first protective shell is inclined downwards. This structure allows debris and coolant to fall off the inclined first protective shell in a timely manner, preventing debris and coolant from accumulating on the shell and reducing the likelihood of debris and coolant falling onto the slide rail and detector, thus minimizing damage to the detection device.

[0017] Compared with the prior art, the built-in detection device provided by the present invention has the following advantages:

[0018] 1. During workpiece processing, this detection device uses a protective cover to cover the probe of the detector, which prevents debris and coolant from falling onto the probe, thus reducing the risk of damage to the detector and the detection device.

[0019] 2. This detection device is equipped with an air blowing pipe, which can blow air onto the detector and protective cover to ensure that no debris or coolant adheres to the detector probe, making the detector and the detection device less prone to damage. Attached Figure Description

[0028] A second driver 7 and a slide rail 8 are fixedly connected to the mounting base 1. A slider 9 is slidably connected to the slide rail 8.

The body 22 of the detector 2 is located in the clearance notch 91, and the detector 2 is fixedly connected to the slider 9. The second driver 7 drives the slider 9 and the detector 2 to move along the slide rail 8. Figure 4 As shown, a dustproof plate 10 is also fixedly connected to the mounting base 1. The dustproof plate 10 is located above the slide rail 8. The edge of the dustproof plate 10 has a dustproof part 101 made of rubber material, and the dustproof part 101 is set against the slider 9.

[0029] A first driver 3, inclined downwards, is fixedly connected to the mounting base 1. A protective cover 4 is fixedly connected to the output shaft 31 of the first driver 3. The side of the protective cover 4 has a clearance hole 41 for the probe 21 of the detector 2 to pass through. The probe 21 is thin and long, and the body 22 is cylindrical. One end of the probe 21 is fixed to the middle of one end of the body 22. Specifically, the protective cover 4 includes a cylindrical protective part 42 at the top and a connecting part 43 fixed to the bottom of the protective part 42. The top of the protective part 42 is closed, and the bottom is through. The protective part 42 is arranged vertically. Figure 5As shown, the clearance hole 41 is located in the side wall of the protective part 42. The side of the protective part 42 has a vent hole 44. Both the clearance hole 41 and the vent hole 44 are elongated and arranged vertically. The vent hole 44 and the clearance hole 41 are arranged opposite to each other. The top of the vent hole 44 is flush with the top of the clearance hole 41, and the bottom of the clearance hole 41 penetrates the protective cover 4. The connecting part 43 protrudes circumferentially relative to the protective part 42 and is fixedly connected to the output shaft 31 of the first driver 3.

After inspection, the second actuator 7 drives the detector 2 to retract, and the first actuator 3 drives the protective cover 4 to be placed over the probe 21 of the detector 2. Then, the workpiece is further machined or the next workpiece is machined. This process is repeated to complete the machining and measurement of multiple workpieces.
