In order to achieve the above object, the utility model provides a following technical scheme: a shaft machining clamp comprises a bottom plate, a first supporting seat and a second supporting seat, wherein the first supporting seat and the second supporting seat are vertically arranged on the bottom plate and provided with arc grooves; a first limiting block is arranged on the outward side of the first supporting seat, and a second limiting block is arranged on the outward side of the second supporting seat; and rib plates are vertically arranged between the bottom plate and the first supporting seat and between the bottom plate and the second supporting seat.

Further, the first pressing seat and the second pressing seat are both provided with arc grooves; the first pressing seat and the first supporting seat and the second pressing seat and the second supporting seat are in limit connection through bolts respectively.

Furthermore, the first limiting block is parallel to the bottom plate and is in screwed connection with the first supporting seat through a bolt; the upper plane of the first limiting block is higher than the bottommost end of the first circular groove of the supporting seat.

Furthermore, the second limiting block is parallel to the bottom plate and is in limiting connection with the second supporting seat through a bolt; the upper plane of the second limiting block is higher than the bottommost end of the circular groove of the second supporting seat.

Furthermore, bolt holes connected with a machine tool are formed in the periphery of the bottom plate.

Compared with the prior art, the beneficial effects of the utility model are that: adding man-hour at the axle, place the axle in the recess of supporting seat one, two, then will compress tightly the seat with the bolt and fix in the supporting seat top, install two stoppers with the bolt respectively on supporting seat one, two around again, screw up the screw again at last, just can fix the axle and carry out the processing operation, stopper one, stopper two can prevent to take place the displacement in the axle course of working, and arc recess has great area of contact with the position of axle installation, effectively prevents to appear rotating in the axle course of working, fixes a position more stably.

After the processing is completed, as long as the bolt of the limiting block is firstly unscrewed, and then the bolt of the pressing seat is dismounted, the workpiece shaft can be taken down, the replacement is quick, and the processing efficiency is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.

Referring to fig. 1-3, a shaft machining fixture includes a base plate 2, a first support seat 31 and a second support seat 32 vertically installed on the base plate 2 and having arc-shaped grooves; a first pressing seat 51 and a second pressing seat 52 are respectively arranged above the first supporting seat 31 and the second supporting seat 32; a first limiting block 41 is arranged on the outward side of the first supporting seat 31, and a second limiting block 42 is arranged on the outward side of the second supporting seat 32; rib plates 6 are vertically arranged between the bottom plate 2 and the first supporting seat 31 and between the bottom plate and the second supporting seat 32.

Specifically, first, as shown in fig. 1-3, a first support seat 31 and a second support seat 32 are fixed on the bottom plate 2 by bolts, and the first support seat 31 is parallel to the second support seat 32; two right-angle sides of the rib plate 6 are respectively fixed with the supporting seat and the bottom plate by bolts; therefore, the structure of the clamp is more stable due to the support of the rib plates 6, and the vibration generated during processing is reduced.

Then, the first limiting block 41 is installed in front of the first supporting seat 31 through bolts and is screwed tightly, so that the upper plane of the first limiting block 41 is higher than the bottommost end of the circular groove of the first supporting seat 31; and then the second limiting block 42 is arranged behind the second supporting seat 32 by bolts, a certain distance is reserved, and the upper plane of the second limiting block 42 is higher than the bottommost end of the circular groove of the second supporting seat 32.

Specifically, when clamping the shaft, a worker firstly puts the shaft 1 into the circular grooves of the first supporting seat 31 and the second supporting seat 32 according to the figure 1, supports against two end faces of the shaft 1 shown in the figure 1 by using the first limiting block 41 and the second limiting block 42, and screws the bolt; then, placing the first pressing seat 51 and the second pressing seat 52 on the shaft 1, and aligning the first pressing seat 51 and the second pressing seat 32 with the first supporting seat 31 and the second supporting seat 32 respectively; finally, the pressing seat and the supporting seat are completely connected and screwed down by bolts according to the figure 1.
