Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding machines, and in particular to an adjustable grinding wheel dressing mechanism for grinding machines. Background Technology
[0002] During grinding, the grinding wheel, as a key component that directly contacts the workpiece, gradually wears down in terms of surface shape and abrasive sharpness, affecting grinding accuracy and efficiency. To restore the shape and performance of the grinding wheel, it needs to be periodically dressed using a dressing wheel. Dressing wheels are typically made of high-hardness materials and are driven by a dressing mechanism to contact the grinding wheel, removing the worn layer from its surface and restoring its ideal geometry and grinding performance.
[0003] However, the existing method of installing dressing wheels has the following problems:
[0004] First, the installation accuracy of the dressing wheel directly affects the dressing effect. In existing technologies, the dressing wheel is usually directly fixed to the dressing mechanism with bolts. Due to the machining errors of the bolts and threaded holes, as well as the fit clearance during the installation process, it is difficult to guarantee the installation accuracy of the dressing wheel, resulting in low installation accuracy and affecting the dressing quality.
[0005] Secondly, the dressing wheel is subjected to radial and tangential forces from the grinding wheel during operation, which easily generates vibration. Under long-term vibration, the conventional bolt fixing method is prone to loosening of the bolts, which leads to a decrease in the connection stiffness between the dressing wheel and the mounting shaft, further aggravating the vibration, forming a vicious cycle, ultimately resulting in a decrease in dressing accuracy, and may even cause safety accidents.
[0006] Therefore, it is necessary to propose an adjustable grinding wheel dressing mechanism to solve the above problems. Utility Model Content
[0007] The main purpose of this invention is to provide an adjustable grinding wheel dressing mechanism for grinding machines, which can effectively solve the problems in the background art.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0009] An adjustable grinding wheel dressing mechanism for a grinding machine includes a base mounted on the grinding machine, an adjustment mechanism provided on the base, a motor detachably mounted on one end of the adjustment mechanism, and a dressing wheel provided at the output end of the motor.
[0010] The motor and the adjustment mechanism are detachably connected by a fixing component. The fixing component includes a fixing seat on the adjustment mechanism and a mounting seat on the motor. The bottom of the fixing seat is provided with a positioning groove, and the top of the mounting seat is provided with a positioning seat that is inserted into the positioning groove. The positioning seat has a certain taper in cross-section. The positioning groove is adapted to the positioning seat. Both ends of the positioning groove are open. Both ends of the fixing seat are provided with limit plates. A first bolt is movably inserted on the limit plate. The fixing seat is provided with a first threaded hole adapted to the first bolt. The end of the first bolt is threaded into the first threaded hole.
[0011] Preferably, one end of the positioning seat is provided with a third threaded hole corresponding to one of the limiting plates, and a second bolt is movably inserted into the limiting plate corresponding to the positioning seat, the end of the second bolt being threadedly engaged with the third threaded hole.
[0012] Preferably, a bayonet is provided on one side of the positioning seat, and a second threaded hole corresponding to the bayonet is provided on one side of the fixing seat. A third bolt is threadedly connected to the second threaded hole, and the end of the third bolt engages with the bayonet.
[0013] Preferably, the adjustment mechanism includes an adjustment frame rotatably mounted on the upper end of the base, a second cylinder is provided at one end of the adjustment frame, the fixed seat is fixed to the bottom output end of the second cylinder, a support is provided at one end of the base, a fixed block is rotatably mounted at the end of the adjustment frame away from the second cylinder, a first cylinder is mounted on the fixed block, and the output end of the first cylinder is rotatably connected to the support via a pin.
[0014] Preferably, a slider is movably disposed inside the first threaded hole, and an elastic element is fixed between the slider and the end of the inner cavity of the first threaded hole.
[0015] Preferably, a ball bearing is movably disposed on the side of the slider away from the elastic element.
[0016] Compared with the prior art, this utility model provides an adjustable grinding wheel dressing mechanism for grinding machines, which has the following beneficial effects:
[0017] This adjustable grinding wheel dressing mechanism uses a fixed component to fix the motor and the dressing wheel in a first-positioning and then-locking manner. This not only makes installation convenient but also provides installation accuracy, thereby ensuring dressing accuracy. The fit between the second bolt and the third threaded hole, as well as the fit between the third bolt and the bayonet, further increases the stability between the positioning seat and the positioning groove.
[0018] The adjustable grinding wheel dressing mechanism of this grinding machine can increase the stability of the first bolt after it is fixed by means of a slider and an elastic element. The reverse force generated by the elastic element acts on the first bolt, increasing the pressure between the thread on the outer wall of the first bolt and the thread on the inner wall of the first threaded hole, thereby increasing stability and reducing the possibility of loosening. The ball can reduce the friction when the end of the first bolt contacts the slider, thus reducing wear. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-4As shown, an adjustable grinding wheel dressing mechanism for a grinding machine includes a base 1 mounted on the grinding machine. An adjustment mechanism is mounted on the base 1, and a motor 7 is detachably mounted on one end of the adjustment mechanism. A dressing wheel 8 is mounted on the output end of the motor 7. Specifically, the motor 7 and the adjustment mechanism are detachably connected via a fixing assembly. The fixing assembly includes a fixing seat 9 mounted on the adjustment mechanism and a mounting seat 11 mounted on the motor 7. The adjustment mechanism includes an adjustment frame 2 rotatably mounted on the upper end of the base 1. A second cylinder 6 is mounted on one end of the adjustment frame 2. The fixing seat 9 is fixed to the bottom output end of the second cylinder 6. A support 3 is mounted on one end of the base 1, and the adjustment frame 2 is located away from the second cylinder. A fixing block 4 is rotatably provided at one end of the 6, and a first cylinder 5 is installed on the fixing block 4. The output end of the first cylinder 5 is rotatably connected to the support 3 through a pin. A positioning groove 10 is provided at the bottom of the fixing seat 9, and a positioning seat 12 is provided at the top of the mounting seat 11 to be inserted into the positioning groove 10. The positioning seat 12 has a certain taper in its cross section. The positioning groove 10 is adapted to the positioning seat 12. Both ends of the positioning groove 10 are open. Limiting plates 13 are provided at both ends of the fixing seat 9. A first bolt 14 is movably inserted on the limiting plate 13. A first threaded hole 16 adapted to the first bolt 14 is provided on the fixing seat 9. The end of the first bolt 14 is threadedly engaged with the first threaded hole 16.
[0026] To further increase the stability between the positioning groove 10 and the positioning seat 12, a third threaded hole 20 corresponding to one of the limiting plates 13 is provided at one end of the positioning seat 12. A second bolt 15 is movably inserted on the limiting plate 13 corresponding to the positioning seat 12. The end of the second bolt 15 is threadedly engaged with the third threaded hole 20.
