Technical Field

[0001] This invention relates to the field of grinding technology, and more specifically to a grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to grind workpieces to obtain the desired shape, size, and precision machined surfaces. Grinding machines are divided into ordinary external cylindrical grinding machines, traditional internal cylindrical grinding machines, coordinate grinding machines, centerless grinding machines, etc. The processing action of a grinding machine is grinding, which occupies a primary position in machining. The sharpening of cutting tools and the precision manufacturing of mechanical parts both rely on grinding. Grinding is also a part of precision machining. The function of a grinding machine is to perform highly precise grinding with very small surface roughness. It can perform high-efficiency grinding and can process materials with very high hardness such as hardened steel and cemented carbide, as well as materials with high brittleness such as glass and granite. The feed rate of a grinding machine not only determines the processing efficiency of the machine tool, but also has an important impact on the surface quality. If the feed rate changes drastically, it will seriously affect the service life of the cutting tools and the machine tool. Therefore, maintaining a high and stable feed rate is particularly important for CNC machining. When using a grinding machine, it is necessary to feed in both the forward and backward and left and right directions. However, there is currently a lack of grinding machines that can simultaneously perform forward and backward feed with left and right feed. Summary of the Invention

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] The following is in conjunction with the appendix Figure 3 and 4 Detailed description: A grinding machine includes a transmission box 101, a ratchet 102, four slide bars I 103, a slider 104, and a spring I 105. The ratchet 102 is rotatably connected to the transmission box 101. Four slide bars I 103 are fixedly connected to the transmission box 101 by welding. The slider 104 is slidably connected to the four slide bars I 103 through a circular hole I. The ratchet 102 has multiple grooves evenly arranged circumferentially. The slider 104 has multiple protrusions, the number and position of which correspond one-to-one with the grooves. The grooves and protrusions cooperate to restrict the rotation of the ratchet 102. The spring I 105 is installed inside the transmission box 101 and between the slider 104. The spring I 105 causes the slider 104 to have a tendency to slide to the right.

[0025] Furthermore, the transmission box 101 is a hollow square box with an open top. The ratchet 102 protrudes to the upper end of the transmission box 101. The slider 104 is provided with four round holes I, which are slidably connected to four slide rods I 103, allowing the slider 104 to slide on the slide rods I 103. The spring I 105 pushes the slider 104 to slide toward the ratchet 102. When the slider 104 is in close contact with the ratchet 102, the protrusion on the slider 104 inserts into the groove on the ratchet 102, causing the ratchet 102 to stop rotating and completing the locking of the ratchet 102. When the slider 104 moves to the right and disengages from the ratchet 102, the protrusion on the slider 104 leaves the groove on the ratchet 102, allowing the ratchet 102 to rotate freely and completing the unlocking of the ratchet 102.

[0026] The following is in conjunction with the appendix Figure 5 and 6 In detail, the grinding machine also includes a feed box 201, a push rod 202, a tension spring 203, and a push rod 204. The push rod 202 is rotatably connected to the feed box 201 via a rotating shaft I. The tension spring 203 is installed between the feed box 201 and the push rod 202. The push rod 204 is fixedly connected to the right side of the feed box 201 by welding.

[0027] Furthermore, the feed box 201 is a hollow square box with an open top. A rotating shaft I is provided inside the feed box 201, and a shaft hole I is provided on the push rod 202. The rotating shaft I is rotatably connected in the shaft hole I, so that the push rod 202 can rotate on the feed box 201. An inclined surface I is provided on the slider 104, and an inclined surface II is provided on the push rod 204. The inclined surface I can slide on the inclined surface II, and the push rod 204 can push the slider 104 to slide away from the ratchet 102.

[0028] The following is in conjunction with the appendix Figure 7-10In detail, the grinding machine also includes a lead screw I 301, a support seat I 302, and a frame 303. The lead screw I 301 is rotatably connected to the transmission box 101. The ratchet 102 is threadedly connected to the lead screw I 301 through a threaded hole I. The two support seats I 302 are rotatably connected to the lead screw I 301 through round holes II. The frame 303 is fixedly connected to the lower end of the two support seats I 302 by welding.

[0029] Furthermore, the frame 303 serves as a support, providing installation space for the support base I 302. Each support base I 302 is provided with a circular hole II, and a lead screw I 301 is rotatably connected to the two circular holes II, so that the lead screw I 301 can be rotatably connected to the two support bases I 302. The ratchet 102 is provided with a threaded hole I at its center, and the threaded hole I on the ratchet 102 is threadedly connected to the lead screw I 301.

[0030] The following is in conjunction with the appendix Figure 7-10 In detail, the grinding machine further includes a locking seat 304, a limiting groove 305, a movable cylinder 306, a limiting shaft 307, a turntable 308, and a spring II 309. The locking seat 304 is fixedly connected to the upper end of the frame 303 by welding. The limiting groove 305 is disposed in the locking seat 304. The movable cylinder 306 is slidably connected in the locking seat 304. The lead screw I 301 is slidably connected to the movable cylinder 306 through a square hole. The limiting shaft 307, which can slide into the limiting groove 305, is fixedly connected to the movable cylinder 306 by welding. The turntable 308 is fixedly connected to the movable cylinder 306 by welding. The spring II 309 is installed between the locking seat 304 and the movable cylinder 306, and the spring II 309 causes the movable cylinder 306 to have a tendency to slide to the left.

[0031] Furthermore, the locking seat 304 provides sliding space for the movable cylinder 306. The locking seat 304 has a circular hole III, through which the lead screw I 301 passes. A square shaft is provided at the end of the lead screw I 301, and a square hole is provided at the center of the movable cylinder 306. The square shaft is slidably connected in the square hole, allowing the movable cylinder 306 to slide relative to the lead screw I 301. The movable cylinder 306 can drive the lead screw I 301 to rotate. When processing begins, the lead screw I 301 needs to be fixed, and the ratchet 102 rotates relative to the lead screw I 301 to enable the grinding table 403 to feed and push the limit shaft 307 in. The limiting groove 305 and the rotating movable cylinder 306, under the action of spring II 309, cause the limiting shaft 307 to slide into the end of the limiting groove 305. The limiting groove 305 will lock the limiting shaft 307, preventing the limiting shaft 307 and the movable cylinder 306 from rotating. The movable cylinder 306 restricts the rotation of the lead screw I 301 that is slidably connected to it, thereby locking the lead screw I 301. After processing is completed, press down the movable cylinder 306 and rotate it. Under the action of spring II 309, the limiting shaft 307 slides out of the limiting groove 305, completing the unlocking of the lead screw I 301. At this time, the turntable 308 can be rotated to adjust the position of the grinding table 403.

[0032] The following is in conjunction with the appendix Figure 10 In detail, the grinding machine also includes a support base II 310 and a slide rod II 311. The two support bases II 310 are fixedly connected to the machine frame 303 by welding, and the slide rod II 311 is fixedly connected to the middle of the two support bases II 310 by welding.

[0033] Furthermore, the support base II310 provides support and installation space for the slide rod II311.

[0034] The following is in conjunction with the appendix Figure 10 In detail, the grinding machine also includes a sliding support 401, a slide rod 402, and a grinding table 403. The two sliding supports 401 are slidably connected to the lead screw 1 301 and the slide rod 2 311 respectively through a round hole 4. The two slide rods 3 402 are fixedly connected between the two sliding supports 401 by welding. The grinding table 403 is slidably connected to the two slide rods 3 402.

[0035] Furthermore, each of the two sliding supports 401 is provided with a set of circular holes IV, which are slidably connected to the lead screw I 301 and the slide rod II 311, respectively. The grinding table 403 is provided with two sets of circular holes V, which are slidably connected to the two slide rods III 402, respectively. The sliding support 401 is provided with an opening I, and the transmission box 101 is provided with an opening II. The push rod 204 can pass through the sliding support 401 and the transmission box 101 through the openings I and II. When the grinding table 403 slides to the right end, the push rod 204 pushes the slider 104 to slide away from the ratchet 102, thus unlocking the ratchet 102. The lever 204 pushes the ratchet 102 to rotate. During the rotation, the ratchet 102 moves forward along the lead screw I 301. The ratchet 102 presses against the transmission box 101 and drives the grinding table 403 to move forward along the lead screw I 301 through the support seat II 310 and the slide rod II 311, realizing the forward and backward feed of the grinding table 403. When the grinding table 403 slides to the left, the push rod 204 is pulled out from the slider 104 to lock the ratchet 102. The push rod 204 slides above the ratchet 102 in the direction of the ratchet teeth without driving the ratchet 102 to rotate, preventing the grinding table 403 from sliding forward and backward during the processing due to the rotation of the ratchet 102, which would cause processing errors.

[0036] The following is in conjunction with the appendix Figure 11 In detail, the grinding machine also includes slide rods IV 501 and transmission rods 502. The two slide rods IV 501 are fixedly connected to the bottom of the grinding table 403 by welding, and the transmission rods 502 are slidably connected to the two slide rods IV 501 through round hole VI.

[0037] Furthermore, the transmission rod 502 is provided with two circular holes VI, which are slidably connected to two slide rods IV 501 respectively, so that the transmission rod 502 can slide along the slide rods IV 501. The two slide rods IV 501 can restrict the degree of freedom of the transmission rod 502, so that the transmission rod 502 can only slide along the slide rods IV 501.

[0038] The following is in conjunction with the appendix Figure 11 In detail, the grinding machine also includes a support base Ⅲ503, a lead screw Ⅱ504, and a motor Ⅰ505. The two support bases Ⅲ503 are fixedly connected to the bottom of the frame 303 by welding. The lead screw Ⅱ504 is rotatably connected to the two support bases Ⅲ503 through a round hole VII. The lead screw Ⅱ504 is threadedly connected to the transmission rod 502 through a threaded hole Ⅱ. The motor Ⅰ505 is fixedly connected to the support base Ⅲ503 by welding. The output shaft of the lead screw Ⅱ504 and the motor Ⅰ505 are fixedly connected by a coupling.

[0039] Furthermore, a circular hole VII is provided on the support base Ⅲ503, and a lead screw Ⅱ504 is rotatably connected in the circular hole VII. A threaded hole Ⅱ is provided at the lower end of the transmission rod 502. The transmission rod 502 is threadedly connected to the lead screw Ⅱ504 through the threaded hole Ⅱ. The motor Ⅰ505 drives the lead screw Ⅱ504 to rotate. When the lead screw Ⅱ504 rotates clockwise, it drives the transmission rod 502 to move to the left. The transmission rod 502 drives the grinding table 403 to move to the left through the two slide rods Ⅳ501. When the lead screw Ⅱ504 rotates counterclockwise, it drives the transmission rod 502 to move to the right. The transmission rod 502 drives the grinding table 403 to move to the right through the two slide rods Ⅳ501, thus completing the lateral feed of the grinding table 403.

[0040] The following is in conjunction with the appendix Figure 12 In detail, the grinding machine also includes a lifting frame 601, a motor II 602, and a grinding wheel 603. The lifting frame 601 is fixedly connected to the machine frame 303, the motor II 602 is fixedly connected to the movable end of the lifting frame 601, and the grinding wheel 603 is fixedly connected to the output shaft of the motor II 602.

[0041] Furthermore, the lifting frame 601 provides support and can adjust the height of the grinding wheel 603 to complete the grinding process.

[0042] The following is in conjunction with the appendix Figure 10 In detail, the grinding table 403 is provided with two mounting slots for mounting fixtures.

[0043] Furthermore, the mounting slot is used to mount and fix the workpiece.
