Description

Technical Field

[0001] This utility model relates to the field of metal grinding technology, and in particular to a grinding wheel dressing device for precision grinding of high-hardness metals. Background Technology

[0002] High-hardness metal precision grinding wheels are suitable for machining hardened steel, cemented carbide, and other materials. They utilize diamond and CBN superhard abrasives with a high-strength binder, exhibiting high wear resistance and shape retention, achieving micron to nanometer-level precision. During use, the abrasive grains are prone to dulling, clogging, and shape deviation, requiring dressing to restore sharpness and geometry to ensure machining accuracy.

[0003] In existing technologies, grinding wheels are often mounted on a specific shaft to achieve horizontal fixation, and then manually rotated to complete multi-angle dressing. However, because manual rotation is difficult to control precisely, and the force and angle are unstable during manual rotation, the freshly dressed grinding wheel may be damaged, compromising accuracy and shape, affecting the overall dressing quality and completion, and failing to meet the high standards required for precision machining. Utility Model Content

[0004] The purpose of this invention is to solve the problem that manual rotation is difficult to control precisely, and the force and angle are unstable when rotating manually, which may damage the newly dressed grinding wheel. Therefore, this invention proposes a grinding wheel dressing device for precision grinding of high-hardness metals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding wheel dressing device for precision grinding of high-hardness metals includes a base plate and a vertical seat fixedly connected to the top of the base plate. A lifting plate is slidably mounted vertically on the vertical seat, and a pair of insert rods are rotatably mounted on the lifting plate. A lower plate is rotatably mounted above the base plate, and a pair of T-shaped slides are slidably connected horizontally on the lower plate. The insert rods and the T-shaped slides are vertically slidably inserted into each other. A sleeve is rotatably connected to one of the T-shaped slides, and a second screw is fixedly connected to the other T-shaped slide. The second screw and the sleeve are threadedly connected. The device also includes: A drive assembly is mounted on the base plate and is used to drive the lifting plate to move vertically.

[0006] Preferably, a motor is fixedly connected to the lifting plate, an upper plate is fixedly connected to the output end of the motor, a cylinder is fixedly connected inside the upper plate, a T-shaped slider is fixedly connected to the output end of the cylinder, the T-shaped slider and the upper plate are slidably connected, and the insertion rod is fixedly connected to the bottom end of the T-shaped slider.

[0007] Preferably, the top of the T-shaped slide block has a slot that facilitates the vertical sliding insertion of the insertion rod.

[0008] Preferably, the driving component includes: Screw 1 is rotatably connected to the vertical seat, and the lifting plate and screw 1 are threadedly connected. A screw rod is fixedly connected to one end of the screw rod that extends to the top of the vertical seat.

[0009] Preferably, the vertical base has a side groove for easy installation of the screw, and the lifting plate and the side groove are vertically slidably connected.

[0010] Preferably, T-shaped grooves are provided on the opposite side walls of the upper plate and the lower plate, and a rotating shaft is rotatably connected to the top of the bottom plate, with the top end of the rotating shaft fixedly connected to the lower plate.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This invention, through the design of upper and lower grinding plates, allows for adjustment of the lower grinding positioning structure according to the grinding wheel size before use. The components work together to bring the two T-shaped slides closer together or further apart, thus securing them against the grinding wheel. A cylinder and motor work together to rotate the upper grinding plate, while the slider and insert rod move synchronously with the lower grinding plate positioning components. The overall rotation of the lower grinding plate coordinates with the rotation of the upper grinding plate, eliminating the need for manual operation, saving time and effort, and ensuring precise rotation, facilitating subsequent precision grinding and dressing of the grinding wheel.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3 A high-hardness metal precision grinding wheel dressing device includes a base plate 1 and a vertical seat 2 fixedly connected to the top of the base plate 1. A lifting plate 3 is vertically slidably mounted on the vertical seat 2. The lifting plate 3 achieves stable vertical position adjustment through vertical sliding engagement with the side groove 31 of the vertical seat 2 and threaded connection with the screw 32. It also supports components such as the motor 5 and the upper plate 4, with high overall structural strength, and can accurately control the height of the upper plate 4 under the action of the drive component. A pair of insertion rods 42 are rotatably mounted on the lifting plate 3. The insertion rods 42 can be vertically slidably inserted into the slots 74 at the top of the T-shaped slide 71. This insertion structure enables rapid positioning and linkage between the upper plate 4 and the lower plate 7. The rigid design of the insertion rods 42 ensures the stability of the transmission between the upper and lower components. The lower plate 7 is rotatably mounted on the top of the base plate 1. The lower plate 7 is rotatably connected to the top of the base plate 1 through a rotating shaft 6, and its horizontal angle can be flexibly adjusted to adapt to grinding wheel dressing operations in different directions. A pair of T-shaped slide blocks 71 are horizontally slidably connected to the lower plate 7. The T-shaped slide blocks 71 slide horizontally on the lower plate 7, and, in conjunction with the threaded drive of the screw 73 and sleeve 72, the distance between the two T-shaped slide blocks 71 can be precisely adjusted. This design can adapt to the fixing requirements of holes on grinding wheels of different sizes. The sliding fit between the T-shaped structure and the lower plate 7 ensures the horizontality during adjustment, preventing offset from affecting the dressing accuracy. Simultaneously, the slot 74 at its top matches the insert rod 42, achieving stable linkage with the upper plate 4. The insert rod 42 and the T-shaped slide blocks 71 are vertically slidably inserted. One T-shaped slide block 71 is rotatably connected to the sleeve 72, and the other T-shaped slide block 71 is fixedly connected to the screw 73. The screw 73 and sleeve 72 are threadedly connected. (The design also includes...) The drive assembly is mounted on the base plate 1 and is used to drive the lifting plate 3 to move vertically.

[0016] A motor 5 is fixedly connected to the lifting plate 3. The output end of the motor 5 is fixedly connected to the upper plate 4. A cylinder 43 is fixedly connected inside the upper plate 4. A T-shaped slider 41 is fixedly connected to the output end of the cylinder 43. The T-shaped slider 41 and the upper plate 4 are slidably connected, and the insertion rod 42 is fixedly connected to the bottom end of the T-shaped slider 41.

[0017] The top of the T-shaped slide block 71 has a slot 74 for vertical sliding insertion of the insertion rod 42.

[0018] Reference Figure 1 The drive assembly includes: screw 32 and screw rod 33.

[0019] Screw 32 is rotatably connected to the vertical base 2, and the lifting plate 3 is threadedly connected to screw 32; the screw rod 33 is fixedly connected to one end of screw 32 extending to the top of the vertical base 2. The vertical base 2 has a side groove 31 for easy installation of screw 32, and the lifting plate 3 is vertically slidably connected to the side groove 31. Rotating the screw rod 33 drives the lifting plate 3 to move vertically. This manual adjustment method is not only simple in structure and low in cost, but also convenient to operate, making it suitable for small-range height fine-tuning scenarios.

[0020] Reference Figure 3 T-shaped grooves 8 are provided on the opposite side walls of the upper plate 4 and the lower plate 7. A rotating shaft 6 is rotatably connected to the top of the bottom plate 1, and the top of the rotating shaft 6 is fixedly connected to the lower plate 7.

[0021] The functional principle of this utility model can be explained through the following operation methods: Before use, adjust the grinding positioning structure on the lower plate 7 according to the size of the grinding wheel to be dressed: Rotate screw 73 to engage with sleeve 72, driving the two T-shaped slides 71 to move closer or further away until the two T-shaped slides 71 vertically pass through the grinding wheel and abut against the grinding wheel; Start cylinder 43, which drives T-shaped slider 41 to slide horizontally in T-shaped slide groove 8 until the insertion rod 42 is directly above T-shaped slide block 71. Rotate the screw 33, which drives the screw 32 to rotate. The screw 32 drives the lifting plate 3 to rise and fall until the insertion rod 42 slides vertically into the T-shaped slide block 71. During the dressing process, the motor 5 is started, and its output end drives the upper plate 4 to rotate. The upper plate 4 moves synchronously with the T-shaped slide block 71 on the lower plate 7 through the T-shaped slider 41 and the insert rod 42. At the same time, the rotating shaft 6 can be rotated to drive the lower plate 7 to rotate as a whole. In conjunction with the rotation of the upper plate 4, the precision grinding and dressing of the grinding wheel is achieved.
