DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] like Figure 1-3 As shown, a horizontal grinder capable of recovering grinding chips comprises a bed 1, a workpiece spindle 2 and a grinding wheel head 3, and also comprises a recovery air duct 4 and a recovery device 5. The workpiece spindle 2 is arranged in the recovery air duct 4, and the grinding wheel head 3 can be extended into the recovery air duct 4 to grind the workpiece. The recovery device 5 is connected to the end of the recovery air duct 4, and the recovery device 5 is used to recover the ground powder.

[0029] The recovery air duct 4 is surrounded by an air slot 41 and a shell 42 arranged on the air slot 41. The air slot 41 is arranged on the bed 1 along the X-axis direction. A slide rail 10 is arranged in the air slot 41 along the X-direction. The workpiece spindle 2 moves along the slide rail 10.

[0030] like Figure 4 As shown, the housing 42 includes a first housing 421 and a second housing 422. There are two first housings 421, which are respectively arranged at the two ends of the wind slot 41, and a second housing 422 is arranged between the two first housings 421. Figure 5 As shown, a processing window 423 is provided on the second housing 422 , and the grinding wheel head 3 extends into the recovery air duct 4 through the processing window 423 .

[0031] The recovery device is used to generate negative pressure in the recovery air duct 4, so that air enters the recovery air duct from the processing window, and then drives the grinding chips into the recovery device. The recovery device can use a high-power fan or other device that can generate negative pressure. In this embodiment, an industrial dust removal device is used, and recovery devices are set at both ends of the recovery air duct.

[0032] The first housing 421 is fixed to the wind slot 41 by bolts, and the other first housing 421 is installed on the wind slot 41 by buckles, which can facilitate the disassembly and assembly of the workpiece. The slide rail 10 is equipped with a bellows to prevent grinding chips from entering the slide rail.

[0033] The grinding wheel head 3 can move along the Y-axis and extend into the recovery air duct from the processing window 423 .

[0034] Furthermore, a measuring device 6 is provided on the bed 1 , and an optical probe is provided at one end of the measuring device 6 close to the recovery air duct 4 , and the optical probe is used to detect the outer diameter of the workpiece being processed.

[0035] like Figure 7 As shown, the measuring device includes a base 12 and a slide 13. The base 12 is fixed on the bed 1. The slide 13 can move along the Y-axis direction on the base 12. The optical probe 11 is fixed on the slide 13. A guide rail 14 is provided on the base 12 along the Y-axis direction. A slider that cooperates with the guide rail 14 is provided on the slide 13. A motor 15 is provided at one end of the base 12 away from the workpiece spindle 2. The motor 15 drives the slide 13 through a lead screw provided on the base 12 and a nut provided on the slide. A grating ruler 17 is provided on the base 12 along the Y-axis direction. The grating ruler 17 can accurately measure the displacement of the optical probe 11 and accurately grasp the processing accuracy.

[0036] Furthermore, there are two optical probes 11, which can be the transmitting end and the receiving end of a laser probe, or other forms of optical probes. The two optical probes 11 are arranged opposite to each other in the vertical direction, and a proximity switch 16 is arranged between the two optical probes 11. The proximity switch 16 is used to measure the distance between the measuring device and the workpiece being processed. One of the two optical probes arranged opposite to each other emits laser light, and the other receives laser light. A reference disk is arranged on the workpiece spindle, and the outer diameter of the reference disk is a standard value.

[0037] Before measurement, the optical probe moves quickly toward the reference disk. When the proximity switch senses that the distance to the reference disk is close, the optical probe moves at a slower speed and slowly approaches the reference disk. When the laser emitted by the optical probe is blocked by the reference disk, the distance moved by the optical probe is accurately obtained through the grating ruler. This distance corresponds to the standard outer diameter of the reference disk, and is used as a reference to measure the outer diameter of the workpiece.

[0038] During measurement, the optical probe approaches the workpiece until the laser is blocked by the workpiece. The outer diameter of the workpiece can be measured by combining this data with the data of the reference disk. When the proximity switch measures that the distance between the workpiece and the measuring device is close to the appropriate range, the optical probe starts working and performs real-time detection of the outer diameter of the workpiece.

[0039] The measurement process is as follows: start the measuring device for calibration, the optical probe moves quickly toward the reference disk 46, when the proximity switch 16 senses that the distance to the reference disk 46 is relatively close, the optical probe moves at a reduced speed and slowly approaches the reference disk, when the laser emitted by the optical probe is just blocked by the reference disk, the distance moved by the optical probe at this time is accurately obtained through the grating ruler, and this distance corresponds to the standard value of the outer diameter of the reference disk, and is used as a reference. In order to obtain more accurate data and eliminate error factors such as the thermal stability of the machine tool itself, repeated measurements are required, and the average value of the measurement results is taken as the final reference value. After calibration, the workpiece is rotated so that the optical probe 11 approaches the workpiece, and the proximity switch 16 detects the relative position with the workpiece to ensure that the optical probe 11 can detect the workpiece and will not collide with the workpiece. The optical probe 11 measures the outer diameter of the workpiece and determines the maximum grinding amount. If it reaches the allowable error range, the next step of grinding can be carried out, and detection is carried out during the grinding process. If it fails, the workpiece will be disassembled.

[0040] Furthermore, if Figure 6 As shown, a detection door 424 is provided on the second housing 422, and a pneumatic rod 425 is provided on the first housing 421, and the pneumatic rod 425 is used to push and pull the detection door 424. When detection is required, the pneumatic rod 425 is activated to open the detection door 424, and the measuring device 6 moves along the Y axis, approaches the workpiece, and performs measurement. After the measurement is completed, the measuring device moves away from the workpiece along the Y axis, the pneumatic rod 425 is activated, and the detection door 424 is closed.

[0041] Embodiment 2:

[0042] like Figure 8 As shown, the workpiece rotates in the recovery duct 4 to generate airflow, so that the air in the recovery duct 4 flows from the first end 401 of the recovery duct 4 to the second end 402 of the recovery duct 4. The difference between this embodiment and embodiment 1 is that in this embodiment, the recovery device 5 is only provided at the second end of the recovery duct, and the first end 401 is open.

[0043] The impeller-type workpiece is clamped on the main shaft. During processing, the impeller rotates at high speed with the main shaft, causing the air flow to flow from the first end 401 to the second end 402. The recovery device 5 is connected to the second end 402, which speeds up the flow of the air flow. The air enters the recovery air duct 4 from the first end, drives the grinding chips, flows to the second end 402, and enters the recovery device 5.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
