Abstract
Description
Technical Field
[0001] The utility model relates to the field of machining, in particular to a portable and efficient grinding wheel dressing device. Background Art
[0002] The cylindrical grinding machine is a commonly used finishing equipment in the machining industry, mainly used for grinding the surface of parts and the end faces with geometric tolerance requirements. Especially when grinding the end face of a part, the side of the grinding wheel needs to be dressed into a concave shape (an acute angle with the outer circle side generatrix) to ensure line-plane contact with the part end face, so as to ensure the geometric tolerance of the part. When the side of the grinding wheel is perpendicular to the outer circle side generatrix and grinding the part end face, the side of the grinding wheel and the part end face are surface-plane contact. On the one hand, due to surface-plane contact, the frictional resistance increases during grinding, which is easy to damage the grinding wheel and is prone to danger under high-speed rotation. On the other hand, when the grinding wheel is manufactured, the side cannot ensure its perpendicular relationship with the rotation axis. During the rotation of the grinding wheel, the force on the part end face is uneven, resulting in out-of-tolerance accuracy. Therefore, it is a very important link to dress the side of the grinding wheel safely and correctly.
[0003] At present, the method for dressing the side of the grinding wheel is as follows: The grinding machine is turned on, the grinding wheel rotates, and the operator holds the diamond pen by experience and feel to dress the side of the grinding wheel. Not only the shape of the grinding wheel is not dressed in place, but also during the operation, the operator needs to be very close to the grinding wheel to observe the shape. If the angle is incorrect, the diamond pen is easy to break the grinding wheel or the finger touches the high-speed rotating grinding wheel, resulting in a safety accident.
[0004] Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention
[0005] The utility model is to solve the above-mentioned deficiencies existing in the prior art, and proposes a device with a simple structure, ingenious design, reasonable layout, simple operation, and capable of realizing high-efficiency dressing of the grinding wheel on the premise of ensuring production safety.
[0006] The technical solution of the utility model is: A portable and efficient grinding wheel dressing device, including a base 1, characterized in that: A turntable 3 is rotatably supported on the base 1 through a rotating shaft 2. A pair of symmetrically distributed limit bolts 4 are arranged on the bottom end surface of the turntable 3. The limit bolts 4 are movably connected in an arc-shaped groove 5 opened on the upper side of the base 1. A sliding sleeve 6 is movably connected in the turntable 3. A diamond pen 7 is inserted at the outer end of the sliding sleeve 6. A fixing set screw 8 matching the diamond pen 7 is threadedly connected to the sliding sleeve 6. A lead screw 9 is also rotatably supported in the turntable 3. One end of the lead screw 9 is connected to a turntable 10 located outside the turntable 3. The turntable 10 and the diamond pen 7 are respectively located at both ends of the turntable 3. A handle 11 is arranged on the turntable 10. At the same time, the lead screw 9 and the sliding sleeve 6 are in threaded connection.
[0007] A sleeve limit block 12 is provided on the top plate of the turntable 3, and the bottom of the sleeve limit block 12 is located in a limit long groove 13 opened at the top of the sliding sleeve 6.
[0008] Angle scale lines 14 matching the arc-shaped groove 5 are drawn on the turntable 3.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] The portable and efficient grinding wheel dressing device of this structural form has a simple structure, ingenious design and reasonable layout. Aiming at the problems existing in the process of grinding and dressing a grinding wheel with a traditional manual-held diamond pen, a special structure is designed. It uses a sleeve to fix the diamond pen, and this sleeve can not only make a swinging motion within a certain range, but also make a telescopic motion along its own axis, so as to drive the diamond pen to move in three-dimensional space, so as to realize the position adjustment of the diamond pen relative to the grinding wheel. It can quickly and accurately control the displacement adjustment of the diamond pen. Compared with the traditional operation method of manually holding a diamond pen, it can effectively ensure the unity and operability of the dressing operation, greatly reduce the dependence on personnel experience, and at the same time improve work efficiency. Therefore, it can be said that it has various advantages and is especially suitable for popularization and application in this field, and its market prospect is very broad. Brief Description of the Drawings

[0012] Figure 2 It is the top view of the embodiment of the utility model.
[0013] Figure 3 It is the schematic diagram of the working state of the embodiment of the utility model. Detailed Embodiment
[0014] The following will describe the detailed embodiment of the utility model in conjunction with the drawings. As Figures 1 to 3As shown: A portable and efficient grinding wheel dressing device, including a base 1 as the foundation. A turntable 3 is rotatably supported on the base 1 through a rotating shaft 2. A pair of symmetrically distributed limit bolts 4 are arranged on the bottom end surface of the turntable 3. The limit bolts 4 are movably connected in an arc-shaped groove 5 opened on the upper side of the base 1. A sliding sleeve 6 is movably connected in the turntable 3. A diamond pen 7 is inserted into the outer end of the sliding sleeve 6. A fixing set screw 8 matching the diamond pen 7 is threadedly connected to the sliding sleeve 6. A lead screw 9 is also rotatably supported in the turntable 3. One end of the lead screw 9 is connected to a turntable 10 located outside the turntable 3. The turntable 10 and the diamond pen 7 are respectively located at both ends of the turntable 3. A handle 11 is arranged on the turntable 10. At the same time, the lead screw 9 and the sliding sleeve 6 are threadedly connected.
[0015] A sleeve limit block 12 is arranged on the top plate of the turntable 3. The bottom of the sleeve limit block 12 is located in a limit long groove 13 opened on the top of the sliding sleeve 6.
[0016] Angle scale lines 14 matching the arc-shaped groove 5 are drawn on the turntable 3.
[0017] The working process of the portable and efficient grinding wheel dressing device of the embodiment of the present invention is as follows: Select a suitable diamond pen 7, insert it into the hole opened at the end of the sliding sleeve 6, and then tighten the fixing set screw 8 to fix the diamond pen 7. As Figure 3 shown, make the tip part of the diamond pen 7 approach the grinding wheel 15 and contact it. Drive the grinding wheel 15 to rotate. The relative movement between the diamond pen 7 and the grinding wheel 15 is realized, so as to achieve the dressing operation of the grinding wheel 15.
[0018] When in use, the turntable 10 and the lead screw 9 can be driven to rotate through the handle 11. Since the lead screw 9 and the sliding sleeve 6 are threadedly connected, and the lead screw 9 is rotatably supported on the turntable 3, the rotation of the lead screw 9 will be converted into the axial movement of the sliding sleeve 6, thereby changing the relative position in the radial direction between the diamond pen 7 and the grinding wheel 15. During the above movement process, the limit long groove 13 will move linearly relative to the sleeve limit block 12, that is to say, the movement of the sliding sleeve 6 will be restricted by the sleeve limit block 12.
[0019] The operator can also hold the handle 11 and drive the turntable 3 to swing to a certain extent around the rotating shaft 2. The swing amplitude is restricted by the arc-shaped groove 5. During the swing process, the operator can judge the current swing angle by observing the angle scale lines 14 drawn on the turntable 3.
[0020] Through the above swing action of the turntable 3, make the tip part of the diamond pen 7 approach the grinding wheel 15. Through the above linear movement of the diamond pen 7, make the diamond pen 7 move along the radial direction of the grinding wheel 15, so as to achieve safe, convenient and efficient dressing operation.
