Description

Technical Field

[0001] This utility model relates to the field of injection mold forming technology, specifically a large grinding machine grinding wheel magnetic seat correction fixture. Background Technology

[0002] Large grinding machines are large precision grinding equipment, mainly used for high-precision planar, cylindrical, or shaped grinding of workpieces made of hard materials such as metals and ceramics. Their core feature is that they achieve micron-level or even submicron-level surface finish and dimensional accuracy by using a high-speed rotating grinding wheel to contact the workpiece. They are widely used in the precision machining of key components in fields such as machinery manufacturing, mold processing, and aerospace.

[0003] In practical production applications, when machining large mold parts, the grinding wheel will wear out severely and needs to be dressed with a dressing tool. Existing dressing fixtures require removing the large part from the worktable, placing the commonly used dressing fixture on the worktable, and using the dressing tool on the dressing fixture to dress the grinding wheel. The grinding cycle of large parts is long, and the grinding wheel wear is severe. Often, a large part needs to be dressed multiple times during the grinding process, which requires repeatedly taking the large part on and off, which is time-consuming, labor-intensive, and inefficient. To address this, we propose a large grinding machine grinding wheel magnetic seat dressing fixture. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This embodiment provides a technical solution: a large grinding machine grinding wheel magnetic seat correction fixture, including a fixture frame 1 and a fixing mechanism 4.

[0018] The fixture frame 1 has a sliding groove 2 at its upper internal end and a mounting groove 3 on its right internal side.

The lower ends of the hexagon socket head cap screws 10 are all in contact with the upper end of the diamond dressing tool 9, providing a basis for the dressing of the grinding wheel.

[0019] The fixing mechanism 4 includes a sliding plate 41, a clamping piece 42, a fixing screw 43, a lead screw 44, a fixing assembly 45, and a transmission assembly 46. The sliding plate 41 is slidably connected to the inside of the slide groove 2. The clamping piece 42 is inserted into the left side of the inside of the sliding plate 41. The fixing screw 43 is threaded to the front and rear sides of the inside of the sliding plate 41, and the inner ends of the fixing screws 43 are in contact with the outer surface of the clamping piece 42. The lead screw 44 is rotatably connected to the middle of the inside of the slide groove 2. A corrugated tube can be added between the sliding plate 41 and the inner wall of the slide groove 2. The corrugated tube is sleeved on the outer surface of the lead screw 44. The corrugated tube will contract and expand as the sliding plate 41 moves, which can prevent the lead screw 44 from being affected by the external environment. The middle of the right side of the inside of the sliding plate 41 is threaded to the outer surface of the lead screw 44, providing a foundation for fixing the workpiece.

[0020] The fixing component 45 is located inside the lower end of the fixture frame 1. The fixing component 45 includes a rotating shaft 451, a first gear 452, a rack plate 453, and a second clamping plate 454. The rotating shaft 451 is rotatably connected to the middle of the lower end of the fixture frame 1. The first gear 452 is located at the left end of the rotating shaft 451. The rack plates 453 are all slidably connected to the lower left side of the fixture frame 1, and all rack plates 453 are meshed with the first gear 452. The second clamping plate 454 is all slidably connected to the middle of the rack plate 453, providing a foundation for fixing the workpiece on both the front and rear sides. Part 45 also includes limiting holes 455 and limiting bolts 456. The limiting holes 455 are all opened on the side of the second clamping piece 454 away from the middle of the first gear 452. The limiting bolts 456 are all threaded to the side of the rack plate 453 away from the middle of the first gear 452. The outer surface of the limiting bolts 456 near the middle of the first gear 452 is inserted into the inner wall of the limiting hole 455. The first clamping piece 42 and the second clamping piece 454 are both L-shaped clamping pieces. The position of the second clamping piece 454 can be adjusted by the limiting holes 455 and the limiting bolts 456 to accommodate workpieces of different sizes.

[0021] The transmission assembly 46 is disposed inside the mounting groove 3. The transmission assembly 46 includes gear 2 461, gear 3 462, gear 463, and gear 5 464. Gear 2 461 is disposed at the right end of the lead screw 44. Gear 3 462 is rotatably connected to the upper end of the left side wall of the mounting groove 3. The three gear 3 462 are vertically adjacent and mesh with each other. The uppermost gear 3 462 meshes with gear 2 461. Gear 463 is rotatably connected to the middle of the left side wall of the mounting groove 3. The lowermost gear 3 462 meshes with the right end of gear 463. Gear 5 464 is fixed. The right end of the rotating shaft 451 is fitted with gear five 464 and gear four 463, which mesh with each other to provide a stable transmission effect for the workpiece fixing operation. The fixing mechanism 4 also includes a magnetic seat 47, which is respectively set on the front and rear sides of the middle of the fixture frame 1. The magnetic seat 47 uses an energized coil to generate a strong magnetic field, and concentrates the magnetic lines of force to the working surface through the iron core magnetic conductor, so that the metal workpiece is firmly attracted. After the power is cut off, the magnetic field disappears and the workpiece is released. The attraction force can be adjusted by the current. It is often used for quick clamping and positioning of machine tools such as grinding machines and milling machines. The magnetic seat 47 can quickly fit with the workpiece surface.

[0022] The fixture also includes a drive knob 5, which is rotatably connected to the lower right side of the fixture frame 1. The left end of the drive knob 5 is fixedly connected to the right end of gear 464, providing a driving effect for fixing the workpiece. It also includes a locking sleeve 6 and a locking knob 7. The locking sleeve 6 is fixedly sleeved on the middle of the outer surface of the rotating shaft 451. The material of the locking sleeve 6 can be a ceramic base material with high friction. The locking knob 7 is threadedly connected to the lower inside of the fixture frame 1. The upper end of the locking knob 7 is fitted with the outer surface of the locking sleeve 6 to provide a locking effect for fixing the workpiece.

[0023] The working principle of this utility model is as follows: When using a large grinding machine grinding wheel magnetic seat dressing fixture to dress the grinding wheel, insert a suitable diamond dressing tool 9 into the installation port 8, and then tighten the internal hex bolt 10 so that the lower end of the internal hex bolt 10 fits against the upper end of the diamond dressing tool 9, thus completing the installation of the diamond dressing tool 9. Then, adjust the work according to the size of the workpiece. When adjusting clamp 42, insert clamp 42 into the appropriate position on the left side of the sliding plate 41, and tighten the fixing screws 43 in sequence so that the inner end of the fixing screws 43 is in close contact with the outer surface of clamp 42. The adjustment of clamp 42 is completed. Then adjust clamp 454. After sliding clamp 454 into the appropriate position inside the rack plate 453, tighten the limiting bolt 456 so that the outer surface of the limiting bolt 456 is inserted into the limiting hole 455 on the side close to the middle of gear 452. The adjustment of clamp 454 is completed. Then, place the jig holder 1 in the appropriate position on the workpiece, and turn the knob on the right side of the magnetic seat 47 to turn on the magnetic seat 47. The magnetic seat 47 generates magnetic force to make the jig holder 1 fit tightly against the surface of the workpiece. At this time, the magnetic force of the magnetic seat 47 alone cannot effectively fix the jig holder 1. Turn the drive knob 5 to drive the gear five 464 and the rotating shaft 451 to rotate. The rotating shaft 451 drives the gear one 452 to rotate, causing the two rack plates 453 to move inward synchronously, and the clamping plate two 454 to move inward synchronously until the inner wall of the clamping plate two 454 is in contact with the outer surface of the workpiece. At the same time, as the gear five 464 rotates, the gear four 464... 63 also rotates, and through the meshing action, the three gears 462 rotate synchronously, eventually driving the gear 461 to rotate. The lead screw 44 also rotates with the rotation of the gear 461. As the lead screw 44 rotates, the sliding plate 41 moves to the right, driving the clamping plate 42 to move to the right synchronously until the inner wall of the clamping plate 42 is in contact with the surface of the workpiece. During this process, through the prior adjustment of the positions of the clamping plate 42 and the clamping plate 454, when the clamping plate 454 is in contact with the surface of the workpiece, the clamping plate 42 is also in contact with the surface of the workpiece at the same time, forming a limiting effect on the upper end and the front and rear sides of the workpiece. To prevent loosening, rotate the locking knob 7. The locking knob 7 moves upward until the upper end of the locking knob 7 is in close contact with the outer surface of the locking sleeve 6. The rotating shaft 451 is locked and will not loosen, thus completing the fixing of the fixture frame 1 to the workpiece surface. At this time, the grinding wheel of the large grinding machine can be adjusted. The fixture is directly fixed to the workpiece surface, avoiding the back-and-forth loading and unloading of the workpiece, which facilitates the rapid processing of large workpieces. It is convenient to operate and highly practical.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
