Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a grinding machine with a grinding wheel dressing mechanism. Background Technology

[0002] With societal development, people have increasingly higher requirements for product precision and appearance. For some metal parts, such as shaft end faces, the surface finish requirements are particularly stringent. Grinding machines can grind the surface of objects to a smooth finish. The outer circumference of the grinding wheel typically has grinding surfaces at different angles. Because the grinding wheel cuts the object's edge using tiny particles on its grinding surface, these particles inevitably fall off during the grinding process, leaving the grinding surface without a precise finish. Therefore, the grinding wheel needs to be dressed. The current dressing method involves removing the grinding wheel after stopping the machine, dressing it with a grinding wheel dresser, and then reinstalling it. This method requires moving the grinding wheel up and down, wasting manpower, reducing work efficiency, and hindering automated operation.

[0003] Chinese patent CN204308761U discloses a grinding wheel dresser, which includes an L-shaped fixing plate mounted on a support column. A cylinder and a guide rail are mounted on the front of the fixing plate. A pad is slidably connected to the guide rail, and a spindle bracket is fixed to the pad by screws. A spindle is mounted on the spindle bracket, and a dressing wheel is mounted on the spindle. The push rod on the cylinder is fixedly connected to the pad. This utility model has a simple structure and reasonable design. The grinding wheel dresser is installed on the inner surface of the support column. When the grinding wheel needs dressing, the machine head only needs to be slid to the grinding wheel dresser to dress the grinding wheel. There is no need to stop the machine to remove and install the grinding wheel, saving manpower, improving work efficiency, and facilitating automated operation.

[0004] The above method involves dressing the grinding wheel face-to-face during grinding, which is not conducive to the formation of a grinding structure on the grinding wheel surface. Utility Model Content

[0005] In view of this, the present invention provides a grinding machine with a grinding wheel dressing mechanism to solve the above-mentioned technical problems.

[0006] A grinding machine with a grinding wheel dressing mechanism includes a grinding machine, a grinding wheel mechanism mounted on the grinding machine, a work clamping mechanism mounted on the grinding machine on one side of the grinding wheel mechanism, and a dressing mechanism mounted on the end face of the work clamping mechanism facing the grinding wheel mechanism. The grinding machine includes a T-shaped support base, a machining mounting portion mounted on the support base, and a grinding wheel mounting portion mounted on one side of the machining mounting portion. The grinding wheel mechanism includes a longitudinal slide rail base mounted on the grinding wheel mounting portion, a grinding slide seat mounted on the longitudinal slide rail base, a grinding motor mounted on the grinding slide seat, a transmission device connected to the output end of the grinding motor, and a grinding wheel mounted on the other end of the transmission device. The work clamping mechanism includes a transverse slide rail base mounted on the machining mounting portion, a machining frame slidably mounted on the transverse slide rail base, a machining motor fixedly mounted on the end face of the machining frame facing away from the grinding wheel mechanism, and a chuck mounted on the end face of the machining frame facing away from the machining motor. The dressing device includes a dressing seat fixedly mounted on the processing frame and facing the grinding wheel mechanism, a dressing motor disposed in the dressing seat, and a dressing wheel disposed at the output end of the dressing motor. The dressing device and the grinding wheel mechanism slide along the transverse slide rail base and the longitudinal slide rail base, respectively. The outer edge of the dressing wheel abuts against the working surface of the grinding wheel. There is an angle between the working end face of the grinding wheel and the dressing wheel, so that when the dressing wheel abuts against the working end face of the grinding wheel, grinding is performed only through the outer edge of the dressing wheel.

[0007] Furthermore, the transverse slide rail base is arranged along the length direction of the processing and mounting part, and the two sides are parallel to each other.

[0008] Furthermore, the transverse slide rail base and the longitudinal slide rail base are arranged perpendicular to each other.

[0009] Furthermore, at least one abutment block is provided at the connection between the processing frame and the transverse slide rail base.

[0010] Furthermore, the end of the dressing seat near the grinding wheel mechanism is inclined outward, forming an angle with the end face of the processing frame.

[0011] Furthermore, the trimming seat is screwed to the processing frame.

[0012] Furthermore, the working surface of the grinding wheel is positioned facing the dressing wheel.

[0013] Compared with the prior art, the grinding machine with a grinding wheel dressing mechanism provided by this utility model sets the dressing device on the side end face of the processing frame, so that it does not need to be installed separately during use, nor does it require additional equipment. The end of the dressing seat near the grinding wheel mechanism is inclined outward, forming an angle with the end face of the processing frame. This creates an angle between the working end face of the grinding wheel and the dressing wheel, so that when the dressing wheel comes into contact with the working end face of the grinding wheel, grinding only occurs through the outer edge of the dressing wheel, i.e., line-to-surface grinding, which increases grinding accuracy. Furthermore, during dressing, teeth can be formed on the working surface of the grinding wheel, improving grinding performance. Attached Figure Description

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 3 The diagram shows a structural schematic of a grinding machine with a grinding wheel dressing mechanism provided by this utility model. The grinding machine with the grinding wheel dressing mechanism includes a grinding machine 10, a grinding wheel mechanism 20 mounted on the grinding machine 10, a work clamping mechanism 30 mounted on the grinding machine 10 and located on one side of the grinding wheel mechanism 20, and a dressing mechanism 40 mounted on the work clamping mechanism 30 and facing the grinding wheel mechanism 20. It is conceivable that the grinding machine with the grinding wheel dressing mechanism also includes other functional structures, such as limiting baffles, drive shafts, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0019] The grinding machine 10 includes a T-shaped support base 11, a machining mounting part 12 disposed on the support base 11, and a grinding wheel mounting part 13 disposed on one side of the machining mounting part 12.

[0020] The load-bearing base 11 can be placed directly on the ground for support. The machining mounting part 12 and the grinding wheel mounting part 13 are used to mount the work clamping mechanism 30 and the grinding wheel mechanism 20, respectively.

[0021] The grinding wheel mechanism 20 includes a longitudinal slide rail base 21 disposed on the grinding wheel mounting part 13, a grinding slide seat 22 disposed on the longitudinal slide rail base 21, a grinding motor 23 disposed on the grinding slide seat 22, a transmission device 24 connected to the output end of the grinding motor 23, and a grinding wheel 25 disposed on the other end of the transmission device 24.

[0022] The grinding sliding seat 22 is slidably mounted on the longitudinal slide rail base 21, and is driven to slide along the longitudinal slide rail base 21 by means of a lead screw and a drive motor (not shown).

[0023] The grinding motor 23 drives the grinding wheel 25, which is connected to the transmission device 24, to rotate. The transmission device 24 is a common device on the market, such as a combination of a transmission belt and a transmission wheel, so it will not be described in detail here. The working surface of the grinding wheel 25 is set towards the dressing mechanism 40 and the work clamping mechanism 30, which facilitates the grinding of the work held on the work clamping mechanism 30, and the dressing mechanism 40 for dressing the grinding wheel 25. The dressing mechanism 40 will be described in detail below.

[0024] The work clamping mechanism 30 includes a transverse slide rail base 31 mounted on the machining mounting part 12, a machining frame 32 slidably mounted on the transverse slide rail base 31, a machining motor 33 fixedly mounted on the end face of the machining frame 32 facing away from the grinding wheel mechanism 20, and a chuck 34 mounted on the end face of the machining frame 32 facing away from the machining motor 33. The machining frame 32 can be driven by an external drive device to slide along the transverse slide rail base 31. The drive device is prior art and will not be described in detail here.

[0025] The transverse slide rail base 31 is arranged along the length of the machining mounting part 12, and its two sides are parallel to each other. The central axes of the transverse slide rail base 31 and the longitudinal slide rail base 21 are perpendicular to each other. The machining frame 32 is slidably mounted on the transverse slide rail base 31 and slides along the transverse slide rail base 31. Its sliding method can be driven by an external motor and a transmission device, the transmission device being the meshing of a screw and a gear. At least one abutment block 35 is provided at the connection between the machining frame 32 and the transverse slide rail base 31, and the machining frame 32 can be fixed by abutting against the transverse slide rail base 31 through the abutment block 35. The output end of the machining motor 33 is arranged facing the grinding wheel mechanism 20, and the chuck 34 is fixedly mounted on the output end of the machining motor 33 and rotates with the machining motor 33. The chuck 34 is used to clamp the workpiece to be processed. The chuck 34 is an existing device, commonly used in lathe machining, so it will not be described in detail here.

[0026] The dressing device 40 includes a dressing seat 41 fixedly mounted on the processing frame 32 and facing the grinding wheel mechanism 20, a dressing motor 42 mounted in the dressing seat 41, and a dressing wheel 43 mounted at the output end of the dressing motor 42.

[0027] Please see Figure 3 The output end of the dressing motor 42 faces the grinding wheel mechanism 20. The end face of the dressing seat 41 where the dressing motor 42 is located is inclined, gradually tilting from the end furthest from the dressing wheel 43 towards the end face furthest from the processing frame 32. That is, the end face of the dressing seat 41 where the dressing motor 42 is located forms an acute angle with the end face of the processing frame 32 facing the dressing seat 41. The dressing seat 41 is screwed to the processing frame 32, so the angle between it and the processing frame 32 can be adjusted by replacing the dressing seat 41 with different specifications, thereby changing the contact angle between the dressing wheel 43 and the grinding wheel mechanism 20. The dressing motor 42 drives the dressing wheel 43 to rotate, thus cooperating with the grinding wheel mechanism 20. Furthermore, there is an included angle between the working end face of the grinding wheel 25 and the dressing wheel 43, so that when the dressing wheel 43 comes into contact with the working end face of the grinding wheel 25, it only makes contact grinding through the outer side of the dressing wheel 43, that is, line-to-face grinding, which improves the grinding accuracy.

[0028] When the grinding wheel shape does not meet the requirements and needs to be dressed, the operator adjusts the processing frame 32 to slide along the transverse slide rail base 31 toward the grinding wheel mechanism 20, and adjusts the grinding sliding seat 22 to slide along the longitudinal slide rail base 21 toward the work clamping mechanism 20, so that the outer edge of the dressing wheel 43 abuts against one side of the working end face of the grinding wheel 25. Then, the dressing motor 42 and the grinding motor 23 are started respectively to rotate the dressing wheel 43 and the grinding wheel 25. The operator operates the external drive device to drive the processing frame 32 to slide along the slide rail base 31, so that the dressing wheel 43 abuts against the grinding wheel 25, grinding the working surface of the grinding wheel 25. Because the dressing wheel 43 and the grinding wheel 25 have a side-to-side contact, teeth are generated on the working surface of the grinding wheel 25, increasing the grinding performance during grinding.

[0029] Compared with the prior art, the grinding machine with a grinding wheel dressing mechanism provided by this utility model eliminates the need for separate installation and additional equipment by setting the dressing device 40 on the side end face of the processing frame 32. The dressing seat 41 is inclined outward at one end near the grinding wheel mechanism 20, forming an angle with the end face of the processing frame 32. This angle between the working end face of the grinding wheel 25 and the dressing wheel 43 ensures that when the dressing wheel 43 contacts the working end face of the grinding wheel 25, grinding is performed only through the outer edge of the dressing wheel 43, i.e., line-to-surface grinding, increasing grinding accuracy. Furthermore, during dressing, teeth are formed on the working surface of the grinding wheel 25, improving grinding performance.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
