Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment and is a bearing grinding wheel dressing device. Background Technology

[0002] In the bearing manufacturing industry, the grinding of bearing raceways is generally performed using grinding wheels with corresponding radius angles, which requires the grinding wheels to have excellent quality and precision. However, existing grinding wheel dressing still largely relies on manual operation, with manual personnel using a diamond pen to dress the grinding wheel. This is not only time-consuming and labor-intensive, but also poses significant safety hazards, and the accuracy is often difficult to guarantee. To address this issue, existing technologies have provided some auxiliary or automatic dressing devices, such as the utility model entitled "A Grinding Wheel Dressing Device for Deep Groove Ball Bearing Raceway Grinding" published in Chinese patent document CN202367596U, authorized on August 8, 2012. This device discloses an automatic device that dresses the grinding wheel by rotating a diamond pen. However, as can be seen from its disclosed technical content, the base position is not adjustable, meaning the overall installation position is relatively fixed, making it difficult to adjust the rotation position and thus difficult to adapt to different grinding wheel dressing operations. Besides, this method of dressing grinding wheels by oscillation mainly involves dressing the radius (R) of the grinding wheel. However, before dressing the R, the thickness of the grinding wheel usually needs to be dressed first. This equipment is clearly not suitable for dressing the thickness of the grinding wheel, requiring a separate thickness dressing device for additional processing. Multiple devices not only increase space requirements but also incur significant costs. Therefore, there is a need to design a device that can simultaneously dress both the grinding wheel thickness and the R. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a bearing grinding wheel dressing device in the field, which solves the technical problems of existing similar dressing equipment having relatively single functions, only having the functions of thickness dressing or radius dressing, failing to achieve dual functions on the same device, and having poor adjustability and limited application scope. This objective is achieved through the following technical solution.

[0004] A bearing grinding wheel dressing device includes a support body, a rotary fixing device for fixing and rotating the grinding wheel, a thickness grinding mechanism for grinding the thickness of the grinding wheel, and an radius grinding mechanism for grinding the radius (R) of the grinding wheel. The key structural feature is that the thickness grinding mechanism and the radius grinding mechanism are arranged on opposite sides of the grinding wheel. The thickness grinding mechanism includes a fixed base, a power cylinder, slide A, slide B, a pen holder, and a first diamond pen. The fixed base is fixed to a horizontal platform on one side of the grinding wheel of the support body, with the X and Y axes as the horizontal plane. A rectangular coordinate system is used, with the Y-axis parallel to the axis of the grinding wheel. The slide A slides relative to the fixed seat along the X-axis. A power cylinder that drives the slide A is fixed to one side of the fixed seat. The slide B slides relative to the slide A along the Y-axis, and a first lead screw that adjusts the slide B is connected to slide A. The pen holder is fixed to the upper surface of slide B, and a pen hole is provided at the end of the pen holder. After the first diamond pen is inserted into the pen hole, a locking screw is radially connected through the pen hole to form a locking fixation. The pen tip of the first diamond pen corresponds to the direction of grinding the… The thickness of the grinding wheel; the R-angle grinding mechanism includes a base plate, a clamping plate, a slide C, a slide D, a rotary cylinder, an L-shaped bracket, and a second diamond pen. The base plate is horizontally fixed within the bracket body. The upper surface of the base plate is provided with the slide C, which slides horizontally, and the lower surface of the base plate is provided with the clamping plate, which slides horizontally. The slide C and the clamping plate are locked together by bolts. The base plate has strip-shaped sliding holes that guide the sliding fit of the bolts. That is, after the slide C is fixed to the clamping plate, it slides horizontally relative to the base plate, and the sliding direction is parallel to the X-axis direction. The base plate is provided with a second lead screw that adjusts the clamping plate to slide relative to the base plate. The slide D slides horizontally relative to the slide C, with the sliding direction parallel to the Y-axis. A third lead screw that drives the slide D to slide is provided on one side of the slide C. The swing cylinder is fixed to the upper end face of the slide D. The output shaft of the swing cylinder is fixedly connected to one end of the L-shaped bracket. The other end of the L-shaped bracket is provided with a pen hole. After the second diamond pen is inserted into the pen hole, it is radially connected to the locking screw through the pen hole to form a locking fixation. The pen tip direction of the second diamond pen corresponds to the R angle of the grinding wheel.

[0005] With the above structure, the thickness dressing and radius dressing of the grinding wheel can be achieved on the same equipment. Both the thickness grinding mechanism and the radius grinding mechanism can achieve bidirectional adjustment of the X and Y axes in the horizontal plane, thus achieving high adjustability and wide applicability.

[0006] The sliding fit between slide A and the fixed seat, between slide B and slide A, and between slide C and slide D are all achieved by a dovetail slider on one side and a dovetail groove on the other side, forming a directional sliding fit. This structure ensures a more precise and reliable sliding fit.

[0007] The first, second, and third lead screws are either manual or electric. The first and third lead screws are positioned at the corresponding dovetail slider and dovetail groove mating points, meaning each lead screw rotates and is positioned within its respective dovetail groove and threadedly engaged with the dovetail slider. The dovetail slider slides relative to the dovetail groove as the lead screw rotates. The second lead screw is threadedly engaged with the clamping plate, and as the second lead screw rotates, the clamping plate slides relative to the base plate. This structure allows for manual or automatic position adjustment of the thickness grinding mechanism and the radius grinding mechanism, making operation convenient and quick.

[0008] The slide C and / or clamping plate are provided with sliders that slide in conjunction with the strip-shaped sliding holes of the base plate. This structure further improves the reliability of the slide C and clamping plate sliding relative to the base.

[0009] This utility model has the function of dressing the grinding wheel thickness and R-angle, and the dressing position is easy to adjust, making it convenient to operate and use. It has higher dressing accuracy and a wide range of applications, making it suitable as a dressing device for grinding wheels or as a structural improvement of similar dressing devices.

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] like Figures 1-6 As shown, the bearing grinding wheel dressing device includes a support body 1, a rotating fixing device 2 that fixes the grinding wheel 3 and drives its rotation, a thickness grinding mechanism 4 that grinds the thickness of the grinding wheel, and an radius grinding mechanism 5 that grinds the radius (R) of the grinding wheel. The support body adopts a frame structure, with its top surface being a horizontal platform surface for supporting the thickness grinding mechanism. The horizontal platform surface is provided with a working opening adapted to the rotation of the grinding wheel and the grinding operation. A horizontal support 101 is provided in the middle of the frame, which supports the aforementioned radius grinding mechanism. The thickness grinding mechanism and the radius grinding mechanism are arranged on both sides relative to the grinding wheel, and their specific structures are as follows.

[0019] The aforementioned thickness grinding mechanism 4 includes a fixed base 402, a power cylinder 401, a slide A 403, a slide B 404, a pen holder 405, and a first diamond pen 406. The fixed base is bolted to a horizontal platform surface on one side of the grinding wheel 3, using the X-axis and Y-axis as a horizontal Cartesian coordinate system, with the Y-axis direction parallel to the axis of the grinding wheel. A dovetail-shaped slider is provided at the bottom of slide A, and a dovetail-shaped groove is provided on the top surface of the fixed base to cooperate with the dovetail-shaped slider. The dovetail-shaped slider and the dovetail-shaped groove cooperate, and a limiting block is fixed to the end of the dovetail-shaped groove with screws, enabling slide A to slide relative to the fixed base in an X-axis orientation. A power cylinder is fixedly mounted on one side of the fixed base; the push rod of the power cylinder connects to slide A and drives slide A to achieve the aforementioned sliding. The bottom of slide B is equipped with a dovetail slider, and the top surface of slide A is equipped with a dovetail groove. The dovetail slider engages with the dovetail groove, and a limiting block is connected to the end of the dovetail groove, allowing slide B to slide relative to slide A along the Y-axis. Slide A is equipped with a first lead screw 407 for positioning rotation. The first lead screw passes through the corresponding dovetail groove, with one end extending out of slide A and connected to a rotating handle, and the other end rotating with the corresponding limiting block. The dovetail slider of slide B has a threaded hole in the middle that engages with the first lead screw. The Y-axis sliding adjustment of slide B relative to slide A is achieved by operating the first lead screw. The top surface of slide B is fixedly connected to a pen holder by bolts. One end of the pen holder has a pen hole, into which the first diamond pen is inserted. A locking screw is radially connected through the pen hole for locking. The pen tip of the first diamond pen corresponds to the thickness of the grinding wheel.

[0020] The aforementioned R-angle grinding mechanism 5 includes a base plate 501, a clamping plate 507, a slide C 502, a slide D 503, a rotary cylinder 504, an L-shaped bracket 505, and a second diamond drill 506. The base plate is horizontally fixed to the crossbar bracket 101 inside the bracket body 1 by bolts 511 and nuts 512. The upper surface of the base plate is provided with a planar sliding slide C, and the lower surface of the base plate is provided with a planar sliding clamping plate. The slide C and the clamping plate are locked together by bolts 508. The base plate is provided with a pair of strip-shaped sliding holes 5011, which form a guiding sliding fit with the bolts. That is, after the slide C and the clamping plate are fixed, they slide horizontally relative to the base plate, and the sliding direction is parallel to the X-axis direction. In order to make the sliding of the slide C and the clamping plate relative to the base plate more reliable and stable, the slide C and the clamping plate may also be provided with sliders 5021 that cooperate with the strip-shaped sliding holes. Below the aforementioned base plate, there is a second lead screw 509 with both ends rotatably positioned on both sides of the base plate. The clamping plate has screw holes that engage with the second lead screw. Rotating the second lead screw causes the clamping plate to slide relative to the base plate, thus enabling the slide block C to slide in a specific direction. One end of the second lead screw is connected to a gear motor on one side of the base plate for electric control adjustment. The upper surface of the slide block C has a dovetail groove, and the lower surface of the slide block D has a dovetail slider that engages with the dovetail groove. Through the engagement of the dovetail groove and the dovetail slider, the slide block D can slide in a specific direction relative to the slide block C. The sliding direction is parallel to the Y-axis, and a limiting block is fixed to the end of the dovetail groove by screws. The slide block C is equipped with a third lead screw 510 that rotates in a positioning manner. The third lead screw passes through a dovetail groove in the slide block C. One end of the third lead screw extends out of one side of the slide block C and is connected to a rotating handle. The other end rotates in a positioning manner with a limiting block at one end of the corresponding dovetail groove. The dovetail slider of the slide block D has a threaded hole in the middle that mates with the third lead screw. The slider D is adjusted relative to the slider C by operating the third lead screw. A swivel cylinder is fixedly connected to the upper end face of the slide block D. The output shaft of the swivel cylinder is fixedly connected to one end of an L-shaped bracket. The other end of the L-shaped bracket has a pen hole. After a second diamond pen is inserted into the pen hole, a locking screw is radially connected through the pen hole to form a locking fixation. The pen tip of the second diamond pen corresponds to the R angle of the grinding wheel.

[0021] The working process of the bearing grinding wheel dressing device is as follows: By adjusting the positions of slide A403 and slide B404 in the thickness grinding mechanism 4, and adjusting the position of the first diamond pen 406 relative to the pen hole, the working position of the first diamond pen is adjusted. After adjustment, the grinding wheel 3 is turned on and the power cylinder 401 is controlled to work. The power cylinder pushes slide A, which drives the first diamond pen into the thickness surface of the grinding wheel for grinding until the required grinding thickness is achieved. After thickness grinding, the power cylinder pulls slide A and exits the thickness grinding mechanism. Next, the R-angle grinding mechanism 5 is adjusted and controlled. First, the positions of slide C502 and slide D503 in the R-angle grinding mechanism are adjusted, and the position of the second diamond pen 506 relative to the pen hole is adjusted to adjust the working position of the second diamond pen. After adjustment, the grinding wheel and the swing cylinder 504 are turned on. The swing cylinder drives the L-shaped bracket 505 to swing. The L-shaped bracket drives the second diamond pen to reciprocate along the R-angle direction of the grinding wheel, thus realizing the grinding of the R-angle of the grinding wheel.

[0022] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Those skilled in the art can make obvious improvements or substitutions to this utility model based on existing common knowledge. For example, designing both the first and third lead screws as electric lead screws, or changing the second lead screw to a manual lead screw, can achieve the same adjustment purpose and also fall within the protection scope of the claims of this utility model.
