[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] Example 1:

[0059] See also Figure 1 - Figure 9 A fixing device for bearing processing includes a workbench 1, and the bearing to be processed is located at the top center position of the workbench 1, ensuring that the position of the bearing to be processed corresponds to the position of the fixing device.

[0060] A gantry 101 is fixedly mounted directly above the center of the top of the work platform 1. A hydraulic lift 2 is fixedly mounted on the gantry 101. The output shaft of the hydraulic lift 2 is connected to the combined frame 3, which contains a clamping control device. The hydraulic lift 2, in conjunction with the gantry 101, enables controlled raising and lowering of the combined frame 3 and its internal structures.

[0061] The combined frame 3 includes an upper cover plate 301 and a lower cover plate 302, with an outer ring 303 and an inner ring 304 disposed between the upper cover plate 301 and the lower cover plate 302. The upper cover plate 301, the lower cover plate 302, the outer ring 303 and the inner ring 304 can be combined to form a circular hollow sealing structure, which can protect the structure inside the cavity of the circular hollow sealing structure.

[0062] The clamping control device is composed of several clamping control components 4, each of which is composed of two clamping control units, so that each clamping control unit can be controlled separately. The corresponding clamping control point can be selected according to the shape of the bearing to achieve clamping and fixation of the bearing.

[0063] The clamping control device includes a main bracket 401, a traction structure 402 is provided in the middle of the main bracket 401, and the bottom end of the main bracket 401 is slidably connected to the main push rod 403. One end of the main push rod 403 passes through the inner ring sleeve 304 and is sleeved with a soft rubber plate 4031. The other end of the main push rod 403 is fixed with a clamping force control structure 404, and the traction structure 402 pulls the clamping force control structure 404 to move.

[0064] The main bracket 401 provides support for the entire clamping control device, wherein the traction structure 402 is used to control the horizontal repeated movement of the main push rod 403, and the main push rod 403 moves synchronously with the soft rubber patch 4031. The soft rubber patch 4031 can contact the outside of the bearing to be processed and then press it. Multiple soft rubber patches 4031 are pressed synchronously to achieve the effect of clamping and fixing the bearing.

[0065] Example 2:

[0066] Based on the above embodiment 1, further description is given.

[0067] See Figure 1 、 Figure 2 、 Figure 3 Specifically, the inner ring sleeve 304 is located inside the outer ring sleeve 303, the thickness and height of the two are equal, and the central axes are collinear.

[0068] When the bearing to be processed is fixed, the bearing is approximately located at the center of the inner ring sleeve 304, thereby facilitating the tightening of multiple points of the bearing.

[0069] The structures of the upper cover plate 301 and the lower cover plate 302 are completely the same, and the two are arranged in an axisymmetric manner.

[0070] It is convenient to exchange the upper cover plate 301 and the lower cover plate 302.

[0071] Specifically, twenty-four support bars 305 are fixedly installed between the side wall of the inner ring sleeve 304 and the side wall of the outer ring sleeve 303, and two support bars 305 form a group. The twelve groups of support bars 305 are evenly distributed in a circular shape with equal angles.

[0072] The support bar 305 forms a support between the side wall of the inner ring sleeve 304 and the side wall of the outer ring sleeve 303. At the same time, most of the structure in the clamping control component 4 can be located between the inner ring sleeve 304 and the outer ring sleeve 303, which is convenient for protecting the clamping control component 4.

[0073] In the same group of support bars 305 , one is located above the cavity between the inner ring sleeve 304 and the outer ring sleeve 303 , and the other is located below the cavity between the inner ring sleeve 304 and the outer ring sleeve 303 .

[0074] The distribution of the control support bars 305 can maintain more space between the inner ring sleeve 304 and the outer ring sleeve 303, reducing the weight of the entire combined frame sleeve 3 and facilitating the subsequent installation of the clamping control assembly 4.

[0075] Specifically, inner screw holes 3051 are provided on the surface of the support bars 305 , and bolts are screwed into the inner screw holes 3051 to fix the upper cover plate 301 , the lower cover plate 302 and the corresponding support bars 305 .

[0076] The connection between the bolts and the inner screw holes 3051 facilitates separation of the combined frame cover 3 , thereby facilitating cleaning of the space inside the combined frame cover 3 and maintenance of the mechanical structure inside the combined frame cover 3 .

[0077] The outer wall of the outer ring sleeve 303 is fixed to the end of the output shaft of the hydraulic lift 2 .

[0078] The hydraulic lift 2 controls the height of the outer ring sleeve 303 , and can control the height of the combined frame sleeve 3 and the clamping control assembly 4 .

[0079] See Figure 3 、 Figure 4 Specifically, several clamping control components 4 are evenly distributed in a ring shape at equal angles, and each clamping control component 4 is controlled by a separate signal.

[0080] Several clamping control components 4 can be combined to form a fixed structure, which can realize multi-point clamping and fixation of the bearing by contacting the soft rubber plate 4031 with the outer wall of the bearing. The setting of the soft rubber plate 4031 can avoid deformation of the bearing during extrusion. At the same time, each clamping control component 4 can independently control the extrusion force of the soft rubber plate 4031 on the bearing, thereby making it convenient to make the extrusion force of each soft rubber plate 4031 on the bearing roughly equal, avoiding bearing deformation caused by uneven clamping force, and ultimately ensuring the processing accuracy of the bearing.

[0081] The two clamping control units in the same clamping control assembly 4 are arranged symmetrically about the upper and lower axes.

[0082] In this way, the two soft rubber plates 4031 in the same clamping control component 4 can be kept as far apart as possible, thereby increasing the effective area when the bearing is clamped and fixed, thereby ensuring the stability of the soft rubber plates 4031 when clamping the bearing.

[0083] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 Specifically, the main bracket 401 is an integrated structure consisting of a flat plate 4011, a hollow bracket 4012, a suspension rod 4013 and a limiting rail 4014.

[0084] The two ends of the flat plate 4011 are fixed to the side walls of the outer ring sleeve 303 and the side walls of the inner ring sleeve 304 by bolts, which can facilitate the installation of the entire main support 401. The hollow support 4012 is fixed to one end of the flat plate 4011, and the bottom of the hollow support 4012 is provided with a type of sliding hole that cooperates with the sliding of the main push rod 403. Utilizing a type of sliding hole, the main push rod 403 can be easily slid. At the same time, since the bearing is located inside the inner ring sleeve 304, when the bearing is processed, the debris generated by the processing can be prevented from entering the inside of the combined frame sleeve 3. The number of the suspension rods 4013 provided is eight, and they are symmetrically and evenly distributed on both sides of the bottom end of the flat plate 4011. The limiting rails 4014 are fixed to the bottom ends of the suspension rods 4013. By providing the suspension rods 4013, more working space is retained on the main support 401, which reduces the weight of the main support 401.

[0085] See Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 Specifically, the traction structure 402 includes a traction motor 4021, which is fixed on the hollow bracket 4012, and the output end of the traction motor 4021 is connected to the winding wheel 4022 through a coupling, and a traction rope 4023 is wound on the winding wheel 4022.

[0086] The traction motor 4021 controls the rotation of the winding wheel 4022 to tighten or release the traction rope 4023 .

[0087] See Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 Specifically, the clamping force control structure 404 consists of a connecting seat 4041, a spring rod 4042, two docking structures 4043 and two pressure sensors 4044.

[0088] The connecting seat 4041 is fixedly installed on the end of the main push rod 403 away from the soft rubber plate 4031. A spring rod 4042 is fixedly installed on one side of the connecting seat 4041. One end of the spring rod 4042 is fixed to the side wall of the inner ring sleeve 304 through a first docking structure 4043 (marked as P in the figure), and the spring rod 4042 always remains in a compressed state.

[0089] When the winding wheel 4022 tightens the traction rope 4023, the spring rod 4042 compresses, causing the connecting seat 4041 to move toward the inner ring 304, thereby pushing the main push rod 403 and the soft rubber plate 4031 to move, causing the soft rubber plate 4031 to contact the bearing and press and secure the bearing. When the winding wheel 4022 releases the traction rope 4023, the elastic force of the spring rod 4042 controls the connecting seat 4041 to move toward the outer ring 303, releasing the soft rubber plate 4031 from pressing and securing the bearing. Simultaneously, the soft rubber plate 4031 separates from the bearing, thus avoiding blind spots in the bearing processing and facilitating the removal of the bearing after processing.

[0090] The other end of the connecting base 4041 is fixed to the second docking structure 4043 (marked as Q in the figure), and the two pressure sensors 4044 are respectively installed inside the two docking structures 4043.

[0091] In this way, the connecting seat 4041 and the second docking structure 4043 (marked as Q in the figure) can move synchronously.

[0092] Specifically, the docking structure 4043 includes a T-shaped mounting plate 40431 and a docking mounting plate 40432, and the T-shaped mounting plate 40431 and the docking mounting plate 40432 are arranged in parallel.

[0093] Two types of sliding holes are provided on the side of the T-shaped mounting plate 40431, and a limiting slide rod 40433 is fixed to the side of the docking mounting plate 40432. One end of the limiting slide rod 40433 passes through the two types of sliding holes and is fixedly installed with the limiting plate 40434.

[0094] The T-shaped mounting plate 40431 and the docking mounting plate 40432 can be moved closer or farther away within a certain range.

[0095] The pressure sensor 4044 is fixed on the T-shaped mounting plate 40431 , and the pressure sensor 4044 is located between the T-shaped mounting plate 40431 and the docking mounting plate 40432 .

[0096] When the T-shaped mounting plate 40431 and the docking mounting plate 40432 are close to each other, pressure is generated on the pressure sensor 4044, thereby causing the reading of the pressure sensor 4044 to change.

[0097] When the T-shaped mounting plate 40431 and the docking mounting plate 40432 are separated, the pressure sensor 4044 can be adjusted, maintained, replaced, etc.

[0098] Specifically, a connector 4045 is hingedly connected to the top of the docking mounting plate 40432 on the second docking structure 4043 (marked as Q in the figure), and the connector 4045 is fixed to one end of the traction rope 4023 .

[0099] In this way, when the traction rope 4023 is tightened, it can drive the connecting head 4045 and the docking mounting plate 40432 on the second docking structure 4043 (marked as Q in the figure) to move, so that the docking mounting plate 40432 contacts the corresponding T-shaped mounting plate 40431. At this time, the corresponding pressure sensor 4044 produces a pressure change, and at the same time, the entire second docking structure 4043 (marked as Q in the figure) moves synchronously.

[0100] A second docking structure 4043 (labeled Q in the figure) is fixedly mounted with an oblique bracket 4046. A T-shaped slider 4047 is slidably connected to the oblique bracket 4046. A fixed pulley 4048 is fixed to the bottom end of the T-shaped slider 4047. The traction rope 4023 is turned through the fixed pulley 4048. The fixed pulley 4048 can be used to change the direction of the traction rope 4023, preventing it from making frequent contact with the main bracket 401 during the tightening and release processes.

[0101] Since the T-shaped slider 4047 slides on the oblique bracket 4046, when the traction rope 4023 is fully released, the traction rope 4023 has a slack margin, and the T-shaped slider 4047 can be manually pulled, and in conjunction with the connecting head 4045, the docking mounting plate 40432 on the second docking structure 4043 (marked as Q in the figure) can be pulled to move, thereby facilitating the separation of the docking mounting plate 40432 on the second docking structure 4043 (marked as Q in the figure) from the T-shaped mounting plate 40431, and then facilitating the operation of the pressure sensor 4044 on the second docking structure 4043.

[0102] A small slider 4049 is fixedly mounted on the side of the second docking structure 4043 (marked as Q in the figure), and the small slider 4049 slides in the limiting track 4014.

[0103] In this way, the stability of the second docking structure 4043 (marked as Q in the figure) and the main push rod 403 during movement can be ensured.

[0104] Working principle:

[0105] First, the bearing to be processed is placed at the top center of the workbench 1, and then the bearing to be processed is clamped using the combined frame sleeve 3 in conjunction with the clamping control device.

[0106] Among them, the hydraulic lift 2 cooperates with the gantry 101 to realize the lifting and lowering control of the combination frame sleeve 3 and the structure inside it. In this way, the clamping control device can adjust the fixed position of the bearing to be processed, and can also control the height of the fixed bearing, which is convenient for processing multiple positions of the bearing to be processed. At the same time, the bearing to be processed is inside the inner ring sleeve 304, and in the inner space of the inner ring sleeve 304, bearings of various shapes can be fixed, which improves the versatility of the fixing device for different bearings.

[0107] During processing, the traction motor 4021 in the traction structure 402 is used as the power source. During clamping, the traction motor 4021 works to control the rotation of the winding wheel 4022 and tighten the traction rope 4023. At this time, the T-shaped mounting plate 40431 and the docking mounting plate 40432 in the second docking structure 4043 (marked as Q in the figure) are tightly attached, and the T-shaped mounting plate 40431, the docking mounting plate 40432, and the connecting head 4045 move synchronously, thereby driving the main push rod 403 to move, and then the soft rubber plate 4031 moves synchronously and presses the bearing to be processed. Multiple soft rubber plates 4031 work synchronously to achieve clamping and fixation of the bearing to be processed.

[0108] As the main push rod 403 moves, the soft adhesive plate 4031 moves synchronously. When the soft adhesive plate 4031 contacts the bearing to be processed, the spring rod 4042 continues to compress, and the value of the pressure sensor 4044 on the first docking structure 4043 (marked P in the figure) continues to increase. When the soft adhesive plate 4031 contacts the bearing to be processed, the spring rod 4042 is no longer compressed. At this time, the value of the pressure sensor 4044 on the first docking structure 4043 (marked P in the figure) remains unchanged, while the value of the pressure sensor 4044 on the second docking structure 4043 (marked Q in the figure) continues to increase. The difference F between the two pressure sensors 4044 roughly represents the compressive force exerted by the soft adhesive plate 4031 on the bearing to be processed. By adjusting the difference F between the different clamping control units to an appropriate and approximately equal value, the fixture can effectively secure the bearing to be processed and prevent deformation caused by excessive force on the bearing.

[0109] At this time, when the bearing can be processed, under the condition of maintaining the fixing effect of the fixing device on the bearing, since the traction structure 402 controls the corresponding soft rubber patch 4031 away from the bearing, at this time, controlling any one or more soft rubber patches 4031 away from or close to the bearing can avoid dead angles in the bearing processing.

[0110] After the bearing processing is completed, the bearing is placed on the workbench 1, and then all the soft rubber plates 4031 are moved away from the bearing and returned to the initial position, so that the bearing can be removed and preparations can be made for the processing of the next bearing.

[0111] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
