As shown in fig. 1, there are an X-axis, a Y-axis and a Z-axis in this embodiment, the X-axis and the Y-axis are perpendicular to each other, and the Z-axis is perpendicular to the X-axis and the Y-axis, i.e., three coordinates of three orientations.

Example one

As shown in fig. 1-2, the primary grinding fixture includes a supporting plate 1, a lateral locking block 2, an inner propping structure 3 and a movable lock catch 4.

Preferably, the support plate 1 of the present embodiment has a disk shape.

The lateral locking block 2 and the bearing plate 1 are locked and fixed together through bolts. The structure of the lateral locking block 2 can be a single straight block structure, an L-shaped or right-angle structure, or a fan-shaped structure.

And the lateral locking block 2 and the bearing plate 1 are integrally formed.

For example, a plurality of bolts are arranged on the bearing plate 1 in a penetrating manner, and a plurality of threaded holes which are in threaded connection with the bolts one by one are arranged on the lateral locking block 2, so that the connection and fixation of the two are realized.

Specifically, the lateral locking block 2 of the present embodiment has two blocks, and of course, the number can be set according to the number of the actual grinding sub-jigs b.

The following is further stated by way of example for two lateral locking blocks 2: the lateral locking blocks 2 are fixed on one surface of the bearing plate 1, and the two lateral locking blocks 2 and one surface of the bearing plate 1 form a sub-jig two-direction locking channel.

The sub-jig two-direction locking channel is used for entering the grinding sub-jig and the sub-jig two-direction locking channel can lock the grinding sub-jig in the Z axis and the Y axis.

The inner propping structure 3 is arranged on one surface of the bearing plate 1 and is positioned at one axial end of the locking channel in the two directions of the sub-jig; the movable lock catch 4 is connected to the bearing plate 1 and is located at the other axial end of the secondary fixture two-direction locking channel.

The inner supporting structure 3 can be designed into a detachable inner supporting structure, can also be designed into a telescopic inner supporting structure, and can be set into a specific structure according to actual use requirements.

Specifically, the inner abutting structure 3 of the present embodiment includes at least one inner abutting block, and of course, the number of the inner abutting blocks may be the same as the number of the two-direction locking channels of the sub-jig, that is, one of the two-direction locking channels of the sub-jig corresponds to one of the inner abutting blocks, so as to achieve one-side abutting positioning of the grinding sub-jig b.

As shown in fig. 1-2, the inner end of the grinding sub-jig abuts against the inner abutting structure 3, and when the movable lock catch 4 is pushed into the two-directional locking channel of the grinding sub-jig, due to its own telescopic characteristic, the movable lock catch 4 sinks under the gravity of the grinding sub-jig, and then when the inner end of the grinding sub-jig abuts against the inner abutting structure 3, the movable lock catch 4 at this time automatically resets and cooperates with the inner abutting structure 3 to lock the two opposite sides of the grinding sub-jig. The mode of this embodiment, the dismouting of the sub-tool of not only being convenient for grind, but also very laborsaving has improved production machining efficiency by a wide margin.

Secondly, a positioning block 10 which protrudes out of one surface of each bearing plate 1 and extends into the locking channel at the two directions of the corresponding sub-jig is arranged on one surface of each bearing plate 1. The positioning block 10 plays a role in heightening and wear resistance, and after heightening, the grinding sub-jig is only contacted with the upper convex surface of the positioning block 10, so that the contact surface of the two-direction locking channel of the grinding sub-jig pushing sub-jig is reduced, and the pushing efficiency are further improved.

The positioning block 10 may be a metal block after quenching.

Each sub-jig has at least one positioning block 10 in the two-direction locking channel, preferably two positioning blocks 10 parallel to each other. The top positioning plane of the positioning block 10 is at the same level to provide a lower support.

And a plurality of positioning groove bodies are arranged on one surface of the bearing plate 1, the positioning block 10 is partially arranged in the positioning groove bodies, and the rest part of the positioning block 10 protrudes out of one surface of the bearing plate 1.

Specifically, the lateral locking is realized by the following scheme: the upper sides of the inner vertical surfaces of the lateral locking blocks 2 are respectively provided with an inner convex limiting part 20, and the transverse section of the locking channel in the two directions of the sub-jig is in a convex shape due to the inner convex limiting parts 20. The grinding sub-jig can be prevented from falling off in the Z axis and the Y axis. The other axial end of the inner vertical surface of the lateral locking block 2, which is positioned in the locking channel at the two directions of the sub-jig, is respectively provided with an inclined guide surface 21, so that the sub-jig can be pushed in from outside to inside.

Secondly, a lock catch mounting hole 11 is formed in the bearing plate 1, the lock catch mounting hole 11 is a through hole structure, the movable lock catch 4 is mounted in the lock catch mounting hole 11, and the upper end of the movable lock catch 4 protrudes out of an upper hole opening of the lock catch mounting hole 11. The lock catch mounting hole 11 is used for mounting and fixing the movable lock catch 4 so as to provide a more stable anti-butting locking function.

Preferably, the movable lock catch 4 of this embodiment is a telescopic elastic lock catch, which is telescopically connected to the supporting plate 1 and located at the other axial end of the secondary fixture two-direction locking channel. Specifically, the movable lock 4 (i.e. the telescopic elastic lock) of the present embodiment includes a hollow seat 40 fixed in the lock mounting hole 11, the hollow seat 40 includes a lower seat and an upper seat, the lower seat and the upper seat are connected to form the hollow seat 40, the bottom surface of the lower seat and the bottom surface of the supporting plate 1 are flush or slightly above, so as to avoid the interference of installation fixation, and the lower end of the telescopic lock 41 extends into the hollow seat 40, a vertical spring 42 is arranged in the hollow seat 40, the lower end of the vertical spring 42 acts on the inner bottom of the hollow seat 40, and the upper end of the vertical spring 42 acts on the lower end of the telescopic lock 41.

When the vertical spring 42 is compressed, it indicates that the grinder assembly is being pushed in or out. When the vertical spring 42 is elastically restored, the polishing sub-jig is in a locked state or pushed out from the two-direction locking channel of the sub-jig. Next, the retractable lock 41 has an arcuate convex surface 43 at its upper end. The arc-shaped convex surface 43 can form a self-adaptive guide to prevent the retractable lock 41 from being compressed downward by itself after contacting with the polishing sub-fixture.

In addition, as shown in fig. 3, a pull ring 12 is hinged to the central region of the other surface of the support plate 1 remote from the lateral locking block 2. The pull ring 12 may facilitate moving the grinding master. Further, a receiving groove is formed in the central region of the other surface of the support plate 1 away from the lateral locking piece 2, the pull ring 12 is connected to the groove bottom or the groove wall of the receiving groove through a hinge structure, and the pull ring 12 is completely received in the receiving groove in a folded state to prevent interference after the support plate 1 is installed.

The working principle of the embodiment is as follows:

the lateral locking block 2 plays a role of Y-axis lateral locking and Z-axis locking grinding sub-jig;

the inner propping structure 3 plays a reference role of propping against the backer from the inner side of the grinding sub-jig;

the movable lock catch 4 can stretch out and draw back after being weighted in the process of pushing in or pushing out the grinding sub-jig so as to be beneficial to the two-direction locking channel of the in-and-out sub-jig of the grinding sub-jig, when the grinding sub-jig abuts against the inner abutting structure 3, the movable lock catch 4 automatically resets, the periphery of the grinding sub-jig is locked, and then the product piece loaded on the grinding sub-jig is ground.

The flatness of the other surface of the bearing plate 1 needs to be processed by a grinding machine so as to ensure that the flatness is controlled within 0.01mm after installation.

And the top surface positioning surface of the positioning block 10 needs to be uniformly processed by a grinding machine to ensure the positioning accuracy, that is, the Z-axis flatness is not influenced by the Z-axis tolerance accumulation of the jig, so as to ensure the final size.

Also, as shown in fig. 2, an inner convex limiting shoulder is provided at the upper opening of the locker mounting hole 11, and an anti-slip shoulder is provided at the lower end of the telescopic locker 41 in the hollow seat 40, which can ensure the telescopic locking without axial disengagement.
