[0001] The utility model relates to the technical field of clamping tooling, in particular to a raceway detection tooling for a slewing bearing. Background Art

[0002] A slewing bearing is a large bearing that can withstand combined loads and can simultaneously withstand large axial and radial loads and overturning moments. The slewing bearing is composed of inner and outer rings, rolling elements, etc. After the inner and outer rings of the slewing bearing are cast, their inner walls need to be grooved to form the raceways for the rolling elements. After the raceways are machined, the raceways on the inner and outer rings need to be inspected.

[0003] When inspecting the raceway of a slewing bearing, in order to ensure the inspection accuracy, the inner and outer rings of the slewing bearing need to be clamped and fixed. The clamping blocks of the existing clamping tool are so close to the workbench surface that when placing or taking the inner and outer rings, it is necessary to pay attention to the height of the inner and outer rings to avoid the inner and outer rings colliding with the clamping blocks. Based on this, in order to prevent the clamping blocks from affecting the placement or removal of the inner and outer rings, a slewing bearing raceway inspection tool is provided.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 In an embodiment of the present invention, a raceway detection tool for a slewing bearing includes a bracket assembly 1 consisting of a workbench 101 and a cross support seat 102. The cross support seat 102 is fixed to the top of the workbench 101. A transmission compartment 103 is provided at the center of the cross support seat 102. Convex rail grooves 104 are provided at the tops of the four straight portions of the cross support seat 102. Receiving grooves 105 and inclined guide grooves 106 are provided at both ends of the convex rail grooves 104 of the cross support seat 102. The receiving groove 105 extends to the top of the cross support seat 102, and the inclined guide groove 106 is connected to the bottom of the receiving groove 105.

[0026] The bottom of the workbench 101 and the interior of the cross support seat 102 are provided with a clamping assembly 2, which is used to clamp and limit the support ring 3;

[0027] The clamping assembly 2 includes a driving motor 201, a driving bevel gear 202, a driven bevel gear 203, a transmission screw 204, a moving block 205, a T-shaped lifting arm 206, a limiting guide rod 207 and a clamping block 208;

[0028] The drive motor 201 is fixed to the bottom of the workbench 101. The output of the drive motor 201 passes through the interior of the transmission compartment 103 and is fixedly connected to the driving bevel gear 202. The driven bevel gear 203 is distributed at one end of the driving bevel gear 202 and meshes with the driving bevel gear 202. The transmission screw 204 is fixed to one end of the driven bevel gear 203 and passes through the storage groove 105 and the convex rail groove 104.

[0029] The moving block 205 is slidably connected to the inner side of the convex rail groove 104 and is threadedly sleeved with the transmission screw 204. The T-shaped lifting arm 206 is vertically slidably connected to one end of the moving block 205, and the upper and lower ends of the T-shaped lifting arm 206 protrude from the upper and lower ends of the moving block 205. The limiting guide rod 207 is fixed to the bottom end of the T-shaped lifting arm 206 and is slidably connected to the bottom of the inner wall of the convex rail groove 104. The clamping block 208 is fixed to the top of the T-shaped lifting arm 206.

[0030] When the clamping blocks 208 are stored in the receiving groove 105, they do not affect the placement and removal of the support ring 3. When the multiple clamping blocks 208 are moved out of the receiving groove 105 and move along the trajectory of the convex rail groove 104, they are used to clamp and limit the support ring 3. The width of the moving block 205 matches the width of the small size part of the convex rail groove 104.

[0031] The width of the moving block 205 matches the width of the small size portion of the convex rail groove 104;

[0032] The width of the limiting guide rod 207 matches the width of the large-size portion of the convex rail groove 104, and the outer diameter of the limiting guide rod 207 matches the height of the large-size portion of the convex rail groove 104;

[0033] The width of the limiting guide rod 207 matches the width of the large-size portion of the convex rail groove 104, and the outer diameter of the limiting guide rod 207 matches the height of the large-size portion of the convex rail groove 104. The width of the receiving groove 105 matches the width of the clamping block 208.

[0034] The inner wall width of the inclined guide groove 106 matches the width of the limiting guide rod 207 , and the horizontal height from the top of the moving block 205 to the top of the cross support seat 102 is greater than the height of the clamping block 208 .

[0035] In this embodiment, when the support ring 3 is clamped by this tool, the operation steps are as follows:

[0036] If the inner ring of the support (support ring 3) is clamped, the inner side of the outer ring of the support is clamped by the clamping block 208. At this time, before placing the support ring 3, the drive motor 201 is started first. The drive motor 201 drives the four driven bevel gears 203 through the active bevel gear 202, thereby causing the four transmission screws 204 to rotate synchronously (it should be noted that the screw threads of the two diagonally distributed transmission screws 204 are in opposite directions), so that the four moving blocks 205 are contracted synchronously. The moving block 205 drives the clamping block 208, the lifting arm 206, and the limiting guide rod 207 to move toward the storage slot 105 and the inclined guide slot 106 close to the transmission compartment 103. When the limiting guide rod 207 moves to the inside of the inclined guide slot 106, the clamping block 208 is located above the storage slot 105. At this time, the bottom of the clamping block 208 loses its limit and moves downward under the action of its own gravity. The limiting guide rod 207 slides down along the inclined inner wall of the inclined guide slot 106, and finally the clamping block 208 is completely stored in the storage slot 105.

[0037] After that, the support ring 3 can be placed on the top of the cross support platform 102, and the position of the support ring 3 is roughly located outside the four clamping blocks 208. Then, the driving motor 201 is reversed to move the clamping blocks 208 out of the receiving groove 105 and move them to fit the inner side of the support ring 3 (such as Figure 1 ), at this point, the centering limit clamping of the support ring 3 is completed, and then the rolling detection operation on the support ring 3 can be carried out by the detection equipment (it should be noted that: the workbench 101 can be fixedly placed, and the detection equipment can be used for circular movement for detection, or the workbench 101 can be installed on a rotating table for circular movement, and the detection equipment can be fixed for detection);

[0038] When clamping the supporting outer ring, the outer side of the supporting outer ring is clamped by the clamping block 208. At this time, the clamping block 208 can be stored in the outer storage groove 105 in advance. After the inspection is completed, the clamping block 208 is reset and stored in the storage groove 105. In this way, when the supporting ring 3 is taken or placed, there is no need to worry about collision with the clamping block 208, and the supporting ring 3 is more convenient and easy to take and place.

[0039] Please refer to Figures 1 to 4 Two T-shaped lifting arms 206 are provided at one end of the moving block 205, and two vertical T-shaped slots are symmetrically opened at one end of the moving block 205 with the transmission screw 204 as the center, and the T-shaped lifting arms 206 are slidably connected to the vertical T-shaped slots;

[0040] One end of the transmission screw 204 away from the driven bevel gear 203 is rotatably connected to the end of the cross support seat 102 .

[0041] In this embodiment, the two T-shaped lifting arms 206 and the vertical T-shaped slots are used to make the lifting operation of the clamping block 208 more stable.

[0042] By rotatably connecting one end of the transmission screw 204 away from the driven bevel gear 203 to the end of the cross support seat 102, the rotation of the transmission screw 204 can be made more stable, thereby ensuring stable use of the equipment.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
