During the grinding process of the machine tool, iron chips will be scattered on the guide rail along with the coolant. As the ejector slide moves on the guide rail, the iron chips scattered on the guide rail will inevitably accumulate between the guide rail and the ejector slide, causing wear to the guide rail and the ejector slide.

DETAILED DESCRIPTION

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1-4 As shown, a CNC cylindrical grinding machine which is easy to adjust comprises an operating table 1, a fixed seat 2 installed on one side of the top surface of the operating table 1, a slide rail 3 transversely fixed on the other side of the top surface of the operating table 1, and a movable slide seat 4 slidably arranged on the slide rail 3, and an ejector pin 5 is installed on one side of the movable slide seat 4 and the fixed seat 2 corresponding to each other;

[0022] When in use, the workpiece to be processed is placed horizontally between the fixed seat 2 and the movable slide 4 in advance, and then the movable slide 4 is driven to slide on the slide rail 3 toward one side of the fixed seat 2 to adjust the distance between the two ejector pins 5 until the two ends of the workpiece are clamped by the two ejector pins 5 respectively, so as to ensure the stability of the workpiece during processing.

[0023] However, in practice, during the grinding process of the machine tool, iron chips will be scattered on the slide rail 3 along with the coolant, and as the movable slide 4 moves on the slide rail 3, the iron chips scattered on the slide rail 3 will inevitably accumulate between the slide rail 3 and the movable slide 4, causing wear to the slide rail 3 and the movable slide 4;

[0024] For this purpose, refer to Figure 1 and Figure 2 As shown, it is worth noting that a movable groove is provided in the inner wall of the movable slide 4, and a receiving mechanism for preventing iron filings from falling on the slide rail 3 is provided in the movable groove;

[0025] The receiving mechanism includes a material collecting seat 6 in a rectangular frame shape and arranged transversely above the slide rail 3. One end of the material collecting seat 6 is fixedly connected to the fixed seat 2, and the other end of the material collecting seat 6 crosses the movable slide seat 4. A filter screen 7 is fixed in the open bottom of the material collecting seat 6.

[0026] By setting the aggregate seat 6 and the filter screen 7, a certain protective barrier can be effectively provided for the slide rail 3 above the slide rail 3, so that the cooling water and iron chips generated by the workpiece processing can enter the aggregate seat 6 in advance and be separated into solid and liquid by the filter screen 7, thereby preventing the iron chips from being scattered directly on the slide rail 3 along with the cooling water, thereby reducing the possibility of the iron chips causing wear to the slide rail 3 and the movable slide seat 4.

[0027] Further, refer to Figure 2 and Figure 3 As shown, it is worth noting that a scraper 8 is vertically arranged on one side of the top surface of the material collecting seat 6, and a driving groove 9 is horizontally opened on the inner walls of the front and rear sides of the material collecting seat 6. A driving component for causing the scraper 8 to reciprocate and move unidirectionally on the surface of the filter screen 7 is arranged in the driving groove 9. One end of the material collecting seat 6 is vertically fixed to the fixed seat 2, and a material drop opening 19 is opened on the other side of the top surface of the filter screen 7. A collecting box 20 corresponding to the material drop opening 19 is arranged on the bottom surface of the material collecting seat 6;

[0028] Through the arrangement of the scraper 8, the driving component and the collecting box 20, when the iron filings are continuously entering the inner side of the collecting seat 6 along with the cooling water, the driving component causes the scraper 8 to intermittently slide unidirectionally along the top surface of the filter screen 7, so that the scraper 8 slides from one side of the top surface of the filter screen 7 to the other side, thereby effectively scraping the scattered iron filings on the filter screen 7 to the drop port 19, and making the iron filings fall from the drop port 19 into the collecting box 20 for centralized collection, so as to facilitate subsequent use by personnel.

[0029] Further, refer to Figure 2 As shown, it is worth noting that the driving component includes two transmission rods 10 symmetrically rotatably arranged on the innermost inner wall of the driving groove 9 and a belt 11 connected between the two transmission rods 10, and a connecting block 12 is vertically fixed on the surface of the belt 11, and the connecting block 12 is detachably connected to the scraper 8;

[0030] A motor 18 is mounted on the side wall of the material collecting seat 6, and the output shaft of the motor 18 rotates to penetrate into the driving groove 9 and is fixedly connected to one of the transmission rods 10;

[0031] When the motor 18 is turned on, the output shaft of the motor 18 can drive one of the transmission rods 10 to provide a circulating operating force for the belt 11, so that the scraper 8 intermittently slides unidirectionally on the top surface of the filter screen 7 under the action of the connecting block 12, and scrapes the iron filings from one side to the collection box 20 on the other side.

[0032] Further, refer to Figure 4 As shown, it is worth noting that mounting grooves 13 adapted to the connecting block 12 are provided on both sides of the scraper 8, and a contraction cavity 14 connected to the mounting groove 13 is provided in the inner wall of the scraper 8, and an elastic clamp is provided in the contraction cavity 14;

[0033] The elastic clamp includes two positioning blocks 15 symmetrically slidably arranged in the contraction cavity 14 and a spring 16 fixed between the two positioning blocks 15. A fixing hole is provided on the connecting block 12, and one end of the positioning block 15 away from the spring 16 is inserted into the fixing hole. A sliding slot communicating with the inside of the contraction cavity 14 is provided on the top surface of the scraper 8, and a pulling block 17 vertically fixedly connected to the positioning block 15 is slidably arranged in the sliding slot.

[0034] After a certain period of use, when the scraper 8 is seriously worn, it is only necessary to simply pull the pull block 17 to cause the positioning block 15 to fall off from the fixing hole under the drive of the pull block 17, so as to release the fixing effect of the connecting block 12 in the mounting groove 13, thereby facilitating manual separation of the connecting block 12 from the scraper 8 and performing replacement and maintenance of the scraper 8 alone;

[0035] Conversely, by pulling the pulling block 17 in advance, the positioning block 15 squeezes the spring 16 to deform during the process of contracting the inside of the contraction cavity 14, and then the connecting block 12 is installed into the mounting groove 13, and the pulling of the pulling block 17 is released. The positioning block 15 can be quickly reset to the fixing hole on the connecting block 12 under the elastic force of the spring 16, and the connecting block 12 is locked to ensure the firmness of the connection between the belt 11 and the scraper 8.

[0036] Further, refer to Figure 2 As shown, it is worth noting that slots are provided on both sides of the top surface of the collecting box 20, and a slide bar 21 fixedly connected to the bottom surface of the collecting seat 6 is slidably provided in the slot;

[0037] After a certain amount of iron filings are collected inside the collecting box 20, the collecting box 20 is slid so that the slide bar 21 is withdrawn from the slot, so that the collecting box 20 and the collecting seat 6 can be separated, and the iron filings in the collecting box 20 can be quickly processed.
