Description

Technical Field

[0001] The utility model relates to the technical field of metal workpiece grinding, in particular to a fixing fixture used for metal workpiece grinding. Background Art

[0002] After metal casting, forging and other processing processes are completed, metal workpieces will be formed. There will be burrs, unevenness and slight differences in size on the surface of the workpiece, so the surface needs to be polished. However, when encountering some special parts to be polished, most of the time the workpiece is fixed on a bench vise and then polished manually.

[0003] The existing patent (Announcement No.: CN216859366U) discloses a fixed fixture for grinding metal workpieces, which can realize the support of the bench vise through the cooperation between the level meter, the support mechanism and the adjustment mechanism. At the same time, the level meter can timely understand the tilt degree of the bench vise, and then the adjustment mechanism can adjust the bench vise, and then keep the bench vise in a horizontal state, so that the waste of the workpiece can be reduced when grinding the metal workpiece, and the problem that the bench vise may tilt after long-term use, and then the workpiece is easily scrapped when grinding the metal workpiece, is solved. In the process of implementing this solution, it is found that the following problems exist in the prior art and have not been well solved:

[0004] When grinding, the workpiece often vibrates violently, which causes the bench vise to vibrate. The threaded structure often moves during the vibration, resulting in insufficient clamping. Secondly, when in use, only workpieces of conventional shapes can be limited and fixed, which limits its use. Utility Model Content

[0032] A sliding groove 17 is provided inside the fixed block 12, and a ball 16 is arranged inside the sliding groove 17. The ball 16 allows the two sides of the sliding rod 15 to move to ensure its convenience in use. The two sides of the sliding groove 17 are connected to the sliding rod 15, and the outer side of the sliding rod 15 is connected to the adjusting block 13. The adjusting block 13 is used to fix the special-shaped workpiece to prevent it from shaking. The outer side of the adjusting block 13 is connected to the rubber block 14.

[0033] See the attached drawings in the specification Figure 1-4 The connection mode between the adjusting screw rod 3 and the device body 2 is a rotational connection, and the connection mode between the adjusting screw rod 3 and the threaded block 4 is a threaded connection. A movable block 8 is also connected above the threaded block 4. The threaded block 4 cooperates with the movable block 8, so that the movable block 8 can change its position by adjusting the screw rod 3 to adapt to different workpiece fixing operations.

[0034] See the attached drawings in the specification Figure 1-4 There are limit blocks 5 symmetrically distributed on both sides of the adjusting screw rod 3. The connection method between the adjusting screw rod 3 and the limit blocks 5 is a rotational connection. There are connecting blocks 6 symmetrically distributed on both sides of the limit blocks 5. The limit blocks 5 and the connecting blocks 6 cooperate to limit the adjusting screw rod 3 to prevent it from shaking due to vibration during use.

[0035] See the attached drawings in the specification Figure 1-4 Shock-absorbing springs 7 are symmetrically distributed on both sides of the connecting block 6, and a shock absorber is also connected to the inside of the shock-absorbing spring 7. The connecting block 6 and the device body 2 form a spring shock-absorbing structure through the shock-absorbing spring 7. The shock-absorbing spring 7 cooperates with the shock absorber to perform shock absorption and buffering, thereby reducing the vibration of the adjusting screw rod 3.

[0036] See the attached drawings in the specification Figure 1-4 The extension block 9 and the insertion rod 10 are connected in a sliding manner, and the insertion rod 10 and the insertion groove 11 are connected in a sliding manner. The insertion grooves 11 are evenly and equidistantly distributed around the center of the adjusting screw rod 3. The extension block 9 cooperates with the insertion rod 10 to fix the adjusting screw rod 3 for a second time to ensure that it will not shake.

[0037] See the attached drawings in the specification Figure 1-4 The inner side of the fixed block 12 is evenly and equidistantly distributed with sliding grooves 17, and the interior of the sliding grooves 17 is evenly and equidistantly distributed with balls 16.

[0039] Working principle: When in use, first, place the workpiece to be polished on one side of the fixed block 12, rotate the adjusting screw 3, so that it and the threaded block 4 have a threaded movement, and under the limit of the device body 2, the threaded block 4 drives the movable block 8 to move, so that the movable block 8 moves toward the fixed block 12. When the movable block 8 is against the workpiece, the workpiece squeezes the adjusting block 13, so that the adjusting block 13 squeezes the sliding rod 15. If the workpiece is a special-shaped workpiece, its protruding part will first squeeze the adjusting block 13, so that the sliding rod 15 behind the adjusting block 13 squeezes the ball 16, and the ball 16 squeezes the sliding rod 15 on the other side, so that the adjusting block 13 tilts until it fits the surface of the special-shaped workpiece, and the adjusting blocks 13 at other positions also undergo the same changes, and the special-shaped workpiece is limited and fixed;

[0040] As mentioned above, when the grinding work is performed, the adjusting screw 3 is vibrated. At this time, the limit blocks 5 on both sides of the adjusting screw 3 cooperate with the connecting blocks 6 to distribute the vibration force to the shock-absorbing springs 7 on both sides, and the shock-absorbing springs 7 cooperate with the shock absorbers to perform shock absorption and buffering to prevent the adjusting screw 3 from vibrating. At the same time, after the adjusting screw 3 adjusts the position of the movable block 8, the insertion rod 10 is pushed downward so that it enters the insertion groove 11, and the adjusting screw 3 is fixed for the second time.

[0041] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
