Description

Technical Field

[0001] This invention relates to the field of mechanical parts processing technology, specifically to an adjustable grinding machine for processing mechanical parts. Background Technology

[0002] Mechanical parts, also known as mechanical components, are the basic elements that make up machinery. They are inseparable individual parts that make up machines. Mechanical parts are often made of metal. After the initial machining of metal mechanical parts, in order to ensure their smooth surface, they are often ground by a grinding machine, such as a surface grinder. By rotating the grinding wheel on the surface grinder, the mechanical part moves in a planar motion at the bottom of the grinding wheel, so that the grinding wheel grinds away part of the surface of the mechanical part, forming a smooth surface.

[0003] Since different mechanical parts have different requirements when grinding, different grinding wheels need to be changed. However, the grinding wheels are fixed to the output end of the rotary drive device by bolts, etc., and the grinding wheels need to be changed manually. The operation process has a low degree of automation and low replacement efficiency, which takes up the processing time of mechanical parts, so further improvements can be made.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-6An adjustable grinding machine for machining mechanical parts includes a frame 1, a machining table 2 slidably connected to the top of the frame 1, a stand 3 disposed at the rear of the frame 1, a mounting shell 4 slidably connected inside the stand 3, a longitudinal drive member 5 disposed between the stand 3 and the mounting shell 4, the longitudinal drive member 5 being used to drive the mounting shell 4 to move up and down relative to the stand 3, a second mounting shell 6 slidably connected to the middle of the first mounting shell 4, a front-rear drive member 7 disposed between the first mounting shell 4 and the second mounting shell 6, the front-rear drive member 7 being used to drive the second mounting shell 6 to move back and forth relative to the first mounting shell 4, and a housing inside the second mounting shell 6. A grinding wheel fixing assembly 8 is provided, which includes a front clamping member and a rear clamping member. The grinding wheel fixing assembly 8 clamps and fixes the grinding wheel through the front clamping member and the rear clamping member. A rotation drive member 9 is provided inside the mounting shell 2 6. The rotation drive member 9 drives the grinding wheel to rotate through the grinding wheel fixing assembly 8. A grinding wheel receiving assembly 10 is fixedly installed on the side of the stand 3. Multiple grinding wheels are provided inside the grinding wheel receiving assembly 10. Switching assemblies 11 are provided on both sides of the stand 3. The switching assemblies 11 move the grinding wheels inside the grinding wheel receiving assembly 10 laterally between the front clamping member and the rear clamping member of the grinding wheel fixing assembly 8.

[0031] Please see Figure 3 The upright frame 3 has receiving slots on both side walls for mounting the longitudinal drive component 5. The longitudinal drive component 5 includes a slide rod 501 fixedly mounted between the two ends of one of the receiving slots, and a threaded rod 502 rotatably connected between the two ends of the other receiving slot of the upright frame 3. The mounting shell 4 has lugs 503 fixedly mounted on both sides. One lug 503 has a sliding hole, and the other lug 503 has a threaded hole. The mounting shell 4 is slidably connected to the slide rod 501 via one lug 503, and threadedly connected to the threaded rod 502 via the other lug 503. An external drive source drives the threaded rod 502 to rotate, thereby causing the assembly of the mounting shell 4 and the two lugs 503 to move up and down along the slide rod 501 and the threaded rod 502. Rubber baffles 504 are fixedly mounted between the upper and lower sides of the lugs 503 and the end faces of the receiving slots of the upright frame 3. The rubber baffles 504 are corrugated. When the mounting housing 4 moves up and down, the upper and lower distributed rubber baffles 504 fold and stretch respectively. The rubber baffles 504 also cover the opening of the receiving slot of the upright 3, thus serving as a dust barrier.

[0032] Please see Figure 4 The front and rear drive component 7 includes a rack plate 701 fixedly mounted on the top of the mounting housing 2 6, and a gear 702 rotatably connected between the two side walls of the mounting housing 1 4, with the gear 702 meshing on the top of the rack plate 701. An external drive source drives the gear 702 to rotate, thereby driving the assembly of the mounting housing 2 6 and the rack plate 701 to move back and forth.

[0033] Please see Figure 5-6The front clamping component of the grinding wheel fixing assembly 8 includes a protective plate 801 fixedly installed at the front end of the mounting housing 6. A front clamping disc 802 is rotatably connected through the surface of the protective plate 801. The front clamping disc 802 has a "convex" shaped cross section. The outer diameter of the front half of the front clamping disc 802 is smaller than the outer diameter of its rear half. A bearing is fixedly installed on the outer side of the front half of the front clamping disc 802. The bearing is fixedly installed through the protective plate 801. The bearing enables the front clamping disc 802 and the protective plate 801 to rotate relative to each other and reduces the friction when the front clamping disc 802 and the protective plate 801 rotate relative to each other. The front clamping disc 802 has insertion holes 803 arranged on its rear side array; the rear clamping component of the grinding wheel fixing assembly 8 includes a rotating shaft 804 that is slidably connected through the mounting housing 6. The front end of the rotating shaft 804 is inserted through the center of the front clamping disc 802. The rear clamping disc 805 is fixedly installed on the surface of the rotating shaft 804 near its front end. Insertion posts 806 are arranged on the front side array of the rear clamping disc 805. The rotating shaft 804 and the insertion posts 806 are used to insert into the grinding wheel. The insertion posts 806 correspond one-to-one with the insertion holes 803, and the insertion posts 806 are inserted into the insertion holes 803. The front clamping disc 802 and the rear clamping disc 805 are clamped on the front and rear sides of the grinding wheel.

[0034] Please see Figure 6 The grinding wheel includes a disc-shaped central skeleton with an annular grinding section fixed on its circumference. The thickness of the disc-shaped central skeleton is greater than the thickness of the annular grinding section. A circular hole is formed at the center of the disc-shaped central skeleton for inserting a drive shaft that drives the grinding wheel to rotate. Connecting holes are arranged in an array through the surface of the disc-shaped central skeleton. A rotating shaft 804 is inserted into the circular hole in the disc-shaped central skeleton of the grinding wheel, and a pin 806 is inserted into the connecting hole of the grinding wheel.

[0035] Please see Figure 5-6 The rotating shaft 804 has an array of inserts 807 arranged on its surface behind the rear clamping plate 805. Two sets of sleeves 808 are fitted on the outer side of the assembly of the rotating shaft 804 and inserts 807. The inner wall of the sleeve 808 has a groove corresponding to the insert 807, and the insert 807 slides through and is connected in the groove. Thus, when the assembly of the rotating shaft 804 and inserts 807 rotates, the sleeve 808 rotates synchronously with the rotating shaft 804. During the rotation of the rotating shaft 804, it can also move back and forth relative to the sleeve 808. Both ends of the sleeve 808 are rotatably connected to support seats 809. The support seats 809 are fixedly installed on the inner wall of the mounting shell 6. Bearings are also fixedly installed on the outer wall of the end of the sleeve 808. The bearings are fixedly installed through the support seats 809. The bearings allow the sleeve 808 to rotate relative to the support seats 809 and reduce the friction of the sleeve 808 rotating relative to the support seats 809.

[0036] Please see Figure 6Two sets of limiting rings 810 are fixedly installed at the rear end of the rotating shaft 804. A push plate 811 is sleeved on the rear end of the rotating shaft 804. A through hole with the same diameter as the rotating shaft 804 is opened through the center of the push plate 811, and the push plate 811 is sleeved on the rotating shaft 804 through the through hole. The two sets of limiting rings 810 are clamped on the front and rear sides of the push plate 811. Cylinders 812 are fixedly installed on the front sides of both ends of the push plate 811, and the cylinders 812 are fixedly installed on the inner wall of the mounting shell 6. Thus, the push plate 811 and the rotating shaft 804 are moved back and forth by extending and retracting the output shaft of the cylinders 812. The shaft 804 moves backward to separate from the front clamping plate 802, facilitating the transfer of the grinding wheel between the shaft 804 and the front clamping plate 802. Then, the shaft 804 moves forward to allow the shaft 804 and the insert 806 to be inserted into the grinding wheel, and the rear clamping plate 805 and the front clamping plate 802 clamp the grinding wheel on both sides to fix the grinding wheel.

[0037] Please see Figure 5-6 The rotating drive component 9 includes a second gear 901 fixedly mounted on the outer wall of one of the sleeves 808. A third gear 902 meshes with the upper side of the second gear 901. A drive motor 903 is fixedly mounted at the center of the third gear 902 and is fixedly mounted on the inner wall of the mounting housing 6. The drive motor 903 drives the third gear 902 to rotate, which in turn drives the second gear 901 to rotate, thereby driving one of the sleeves 808 to rotate, and further driving the rotating shaft 804 to rotate. Thus, after the rotating shaft 804 is inserted into the grinding wheel, it can drive the grinding wheel to rotate synchronously, meeting the needs of grinding mechanical parts.

[0038] Please see Figure 7-8 The grinding wheel receiving assembly 10 includes a vertical plate 1001 fixedly installed on the side of the stand 3. Mounting covers 1002 are fixedly installed on both sides of the vertical plate 1001. A trapezoidal groove 1003 is formed in the middle of the front side of the vertical plate 1001. Two sets of slide rails 1004 are fixedly installed on the front side of the vertical plate 1001. An electric slider 1005 is slidably connected to the surface of the slide rails 1004. A bearing plate 1006 is fixedly installed on the front side of the electric slider 1005. Multiple fixed discs 1007 are fixedly installed on the front side of the bearing plate 1006. A guide hole 1008 is provided through the center of the fixed plate 1007. Two sets of arc-shaped springs 1009 are provided on the front side of the fixed plate 1007. The middle of the arc-shaped springs 1009 is fixedly mounted on the fixed plate 1007. The two sets of arc-shaped springs 1009 are used to clamp the upper and lower sides of the grinding wheel. Both ends of the arc-shaped springs 1009 are inclined, tilting away from the center of the arc-shaped springs 1009, facilitating the insertion of the grinding wheel between the two sets of arc-shaped springs 1009 from the left and right sides. The distance between the fixed plate 1007 and the front plate of the mounting cover 1002 is equal to the thickness of the disc-shaped central frame of the grinding wheel. When the grinding wheel is inserted between the two sets of arc-shaped springs 1009, the grinding wheel is in contact with the side of the fixed plate 1007 opposite to the front plate of the mounting cover 1002.

[0039] Please see Figure 7-8 A support column 1010 is slidably connected within the guide hole 1008. A spring 1011 is fixedly installed between the rear half of the support column 1010 and the rear side of the support plate 1006. An annular flange 1012 is fixedly installed on the surface of the support column 1010 near its front end. The diameter of the annular flange 1012 is equal to the diameter of the guide hole 1008. The rear end of the support column 1010 is attached to the front side of the vertical plate 1001. The support column 1010 is used to insert into the center of the grinding wheel. The annular flange 1012 and the front side plate of the mounting cover 1002 clamp the two sides of the grinding wheel. Thus, when the support plate 1006 moves up and down with the electric slider 1005, the support column 1010 slides against the front side of the vertical plate 1001. Under the squeezing action of the vertical plate 1001, the support column 1010 is kept inserted into the center of the grinding wheel. When the support column 1010 slides into the trapezoidal groove 1003, it is pulled out from the center of the grinding wheel under the elastic action of the spring 1011. Both sides of the mounting cover 1002 have through-holes 1013. The length of the through-hole 1013 is greater than the diameter of the grinding wheel, and the width of the through-hole 1013 is greater than the thickness of the disc-shaped central frame of the grinding wheel. The through-hole 1013 is used for the grinding wheel to enter and exit.

[0040] Please see Figure 9 The switching component 11 includes two sets of L-shaped brackets 1101 fixedly installed on both sides of the upright 3. A sliding rod 1102 and a threaded rod 1103 are provided between the vertical part of the L-shaped bracket 1101 and the side of the upright 3. The sliding rod 1102 is fixedly installed on the upright 3, and the threaded rod 1103 is rotatably connected to the upright 3. A pulley 1104 is fixedly installed on one end of each of the two sets of threaded rods 1103. A pulley 1105 is provided directly above the pulley 1104. A transmission belt 1106 is sleeved on the outside of the pulley 1104 and the pulley 1105. A connecting shaft 1107 is fixedly installed between the two sets of pulleys 1105. The connecting shaft 1107 is rotatably connected to the top of the upright 3. The connecting shaft 1107 is driven to rotate by an external drive source. Then, through the transmission action of the pulley 1105, the transmission belt 1106 and the pulley 1104, the two sets of threaded rods 1103 are driven to rotate synchronously.

[0041] Please see Figure 9-11Sliding seats 1108 are provided on the outer sides of sliding rod 1102 and threaded rod 1103. Sliding seats 1108 have sliding holes corresponding to sliding rod 1102 and threaded holes corresponding to threaded rod 1103. Thus, when the two sets of threaded rods 1103 rotate, they drive the two sets of sliding seats 1108 to move simultaneously in the same direction. Connecting arms 1109 are fixedly installed at the front ends of each sliding seat 1108. Two sets of U-shaped plates 1110 are fixedly installed at opposite ends of each set of connecting arms 1109. The two sets of U-shaped plates 1110 are used to clamp the front and rear sides of the grinding wheel and are fitted onto the outer side of the flange of the protruding annular grinding part of the grinding wheel's disc-shaped central skeleton. Each U-shaped plate 1110 has upper and lower supports, with a limiting protrusion 1111 integrally formed on opposite sides of each support. The limiting protrusion 1111 further limits the end of the disc-shaped central skeleton of the grinding wheel.

[0042] In use, S1, the threaded rod 502 is rotated by an external drive source, which causes the assembly of mounting shell 4 and lug 503 to move up and down along slide rod 501 and threaded rod 502, so that the grinding wheel installed at the front end of mounting shell 6 is at the same height as the discharge port 1013.

[0043] S2. Then, the gear 702 is driven to rotate by the external drive source, which drives the rack plate 701 and the assembly of the mounting shell 6 to move back and forth, so that the installed grinding wheel is moved to the right side of the discharge port 1013.

[0044] S3. Then, the connecting shaft 1107 is driven to rotate by the external drive source. With the transmission action of the pulley 1105, the transmission belt 1106 and the pulley 1104, the two sets of threaded rods 1103 rotate synchronously, thereby driving the two sets of sliding seats 1108 to move to the left. The connecting arm 1109 and the U-shaped plate 1110 on the left are pulled out from the discharge port 1013. The U-shaped plate 1110 on the right is fitted onto the end of the disc-shaped central skeleton with the grinding wheel installed, and is clamped on the front and rear sides of the annular grinding part with the grinding wheel installed by the two U-shaped plates 1110.

[0045] S4. Then, the output shaft of cylinder 812 extends, pushing the push plate 811 to move backward, thereby driving the rotating shaft 804 to move backward and pull it out from the installed grinding wheel.

[0046] S5. Then, the threaded rod 1103 continues to rotate, and the connecting arm 1109 on the right side continues to move to the left, so that the installed grinding wheel continues to move to the left along with the U-shaped plate 1110 on the right side and is inserted into the discharge port 1013. Then, it is inserted into the front side of one of the fixed plates 1007 that does not have a grinding wheel installed. The right end of the arc spring 1009 is squeezed by the grinding wheel and deflects outward.
