Technical Field

[0001] The utility model relates to the technical field of bearing roller processing, in particular to a roller tightening and pulling mechanism of a spherical base surface grinder. Background Art

[0002] The ball base surface grinder for bearing rollers performs spherical grinding on the roller end faces. In the past, the requirements for the surface roughness and spherical accuracy of the spherical base surface were relatively low. During the processing of the corresponding processing machine tools, the stability of the tightening pressure at the tail end of the roller was not high, resulting in poor consistency in surface roughness and processing allowance. After the processing is completed, the roller needs to be pulled out to the discharge port. In the past, most of the pull hooks were rigid pull hooks, which easily caused scratches on the roller surface during discharge.

[0030] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0031] like Figure 1-6 As shown, a roller tightening and pulling mechanism for a ball-based surface grinder comprises a workbench, a turntable 1 circumferentially rotatably arranged on the workbench, and a material control assembly 2. The workbench is located on the top of the turntable 1 and is fixedly mounted with a roller stopper 3 and a material stopper plate 4. A material outlet is formed between the roller stopper 3 and the material stopper plate 4. On the one hand, the roller stopper 3 can be used to allow the material control assembly 2 to bring the roller to one side of the roller stopper 3. Then, during grinding, the roller stopper 3 can be allowed to abut against the roller, so that the rotation of the turntable 1 can promote the circumferential rotation of the roller. On the other hand, the material stopper plate 4 can be used to allow the material control assembly 2 to bring the roller to one side of the material stopper plate 4. Then, the rotation of the turntable 1 can lead out the roller. A grinding wheel 5 is provided on the side of the workbench close to the turntable 1.

[0032] The material control component 2 includes a support 201, and the workbench is located above the turntable 1 and fixedly installed with the support 201. The support 201 is slidably connected to a slider 202 inside. A cylinder 211 is fixedly installed on the side of the support 201. The output end of the cylinder 211 passes through the support 201 and is connected to the slider 202. The slider 202 can be controlled to slide back and forth by the extension and contraction of the cylinder 211, so that the slider 202 drives the roller block 3 and the material baffle plate 4 to reciprocate. The slider 202 is slidably connected with a fixed plate 203 and a fixed block 204. The slider 202 is provided with a T-shaped groove. The fixed plate 203 and the fixed block 204 are connected to the T-shaped block through the T-shaped block. The fixing plate 203 and the fixing block 204 are connected by sliding in the groove, and the fixing plate 203 and the fixing block 204 are both threadedly connected with positioning bolts. By using the T-shaped block and the T-shaped groove, the fixing plate 203 and the fixing block 204 can slide on the slider 202, so that the spacing between the fixing plate 203 and the fixing block 204 can be adjusted according to needs during use, so as to adapt to workpieces of different lengths. After the adjustment, the fixing plate 203 and the fixing block 204 can be positioned by the positioning bolts. The bottom of the fixing block 204 is hingedly connected with a swing rod 205, and the side of the fixing block 204 close to the swing rod 205 is threadedly connected with a screw 206, and the swing rod 205 and the screw 206 are connected by the first An elastic member 207 is connected in cooperation, a first movable groove is provided on the side of the fixed block 204 close to the swing rod 205, the swing rod 205 is hingedly connected to the fixed block 204 through a pin, a movable hole is provided on the side of the swing rod 205 located on the screw 206, the diameter of the movable hole is larger than the diameter of the screw 206, the first elastic member 207 is a compression spring, so that a pre-tightening force can be applied to the swing rod 205 through the compression spring when in use, a hook 208 is hingedly connected to the end of the fixed plate 203 away from the slider 202, a second movable groove is provided on the side of the fixed plate 203 close to the hook 208, the hook 208 is hingedly connected to the fixed plate 203 through a pin, and the hook 208 is connected to the fixed plate 203. The fixed plates 203 are connected by a second elastic member 209, which is a tension spring. The side of the rocker arm 205 close to the hook 208 is rotatably connected with a top 210. On the one hand, the top 210 presses against the tail end of the roller and compresses the compression spring (first elastic member 207). Since the compression amount of each roller is basically the same, the force of the spherical base surface at the front end of the roller acting on the grinding wheel 5 is basically equal, so that the rollers maintain the same grinding effect. On the other hand, when the roller passes through in the positive direction, the hook 208 turns inward to avoid the roller. After passing through, the hook 208 is reset under the action of the tension spring (second elastic member 209). When returning in the opposite direction, the roller is pulled away to the discharge port.

[0033] The working process is as follows:

[0034] S1, when working, the output end of the cylinder 211 retreats, and then the slider 202 drives the roller block 3 and the material blocking plate 4 to retreat, so that the hook 208 and the top 210 retreat together and make way;

[0035] S2, the workpiece can enter the working position smoothly at this time. After the workpiece enters, the output end of the cylinder 211 moves forward, and then the slider 202 drives the roller block 3 and the material blocking plate 4 to move forward, so that the hook 208 and the top 210 move forward together;

[0036] S3, using the top 210 to support the tail end of the workpiece, the hook 208 is reset to the front end of the workpiece, and the workpiece is ground by the grinding wheel 5;

[0037] S4, after the processing is completed, the output end of the cylinder 211 retreats, and then the slider 202 drives the roller block 3 and the material blocking plate 4 to retreat, so that the hook 208 and the top 210 retreat together;

[0038] S5. By using the baffle plate 4, the material control component 2 can bring the roller to one side of the baffle plate 4, and then guide the roller out through the rotation of the turntable 1, and wait for the next workpiece to enter, and the cycle continues.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
