As shown in fig. 1-8, the preferred embodiments of the present application are:

an auxiliary supporting structure 11, the auxiliary supporting structure 11 is embedded in the lathe flange 12, the auxiliary supporting structure 11 comprises a supporting main body 111, and a supporting pin 112 and an elastic piece 113 which are arranged in the supporting main body 111, and the top end of the supporting pin 112 is suitable for axially protruding the lathe flange 12 and propping against the workpiece 2 under the action of the elastic piece 113.

As shown in fig. 1, when the workpiece 2 is a part having a relatively complex structure, it mostly has a portion which is light and thin in structure, has a certain distance from the supporting reference and is not coplanar with the reference, and if only a conventional supporting means is adopted, the supporting column 13 cannot be arbitrarily added here because of being limited by the structure of the workpiece 2, so that the vibration of the knife is extremely easy to occur when processing the portion, and the inventor of the present application found that if the non-movable support is added here, there is a gap with the reference surface, resulting in poor flatness of the finish turning process. If the technical problems are not considered, the problem that in the part production process, the rigidity of the part is insufficient, the supporting point of the clamp cannot be increased due to the fact that the supporting point is insufficient (limited by the part structure), after the part is machined, the flatness of the mounting surface of the part is out of tolerance, the production cannot be stabilized, the whole size needs to be checked for ensuring the delivery quality, manpower and material resources are input, the size is related to the perpendicularity of the shaft hole mostly, a size chain cannot be controlled during repair, the repair difficulty is high, the rejection rate is high, great impact is generated on the production benefit, the production benefit is caused to slide downwards, and the efficiency is reduced or even the part exchange period is influenced. In this regard, this application has increased an elasticity formula auxiliary stay here, not only can effectively avoid above-mentioned technical problem to elasticity formula auxiliary stay compares other conventional pneumatic and spiral, has the advantage of better precision and security.

However, since the structure of the workpiece 2 is special, the supporting column 13 interferes with the surrounding blank surface after being thickened to affect the rigidity of the lathe flange 12, and since the elastic auxiliary supporting structure 11 needs to consider the limit compression amount of the elastic element 113 and reserve the stroke, the supporting column 13 must be pulled up when the supporting structure is installed, if the conventional elastic auxiliary supporting structure 11 is installed, the supporting column 13 needs to be lengthened under the condition that the workpiece cannot be thickened, the rigidity of the supporting column is influenced, if the auxiliary supporting structure is installed, the cutter vibration phenomenon still occurs, and the use requirement cannot be met. To this, this application has adopted the technical means of embedded connection, in embedding lathe flange 12 with auxiliary support structure 11 for lathe flange 12's thickness also fuses into the part in the vertical space of elasticity formula auxiliary support structure 11, thereby realized under the length that does not change support column 13, also mountable elasticity formula auxiliary support structure 11, so that this application can not produce the influence to lathe flange 12 and support column 13's rigidity when increasing frock datum point promotion part rigidity, greatly promote the qualification rate of part and convenient operation and maintenance.

As shown in fig. 4 and 5, specifically, in this embodiment, the auxiliary support structure 11 is embedded in the lathe flange 12 in such a manner that: the support body 111 is provided on the back surface of the lathe flange 12, and the tip end of the support pin 112 is adapted to protrude from the front surface of the lathe flange 12 by the elastic member 113. The structure is simple and stable, and the thickness of the lathe flange 12 is greatly fused into a part of the longitudinal space of the elastic auxiliary support structure 11, so that the modification of the height of the support column 13 during the installation of the auxiliary support structure 11 can be effectively avoided, and the sufficient rigidity of the support column 13 is ensured.

Further, in the present embodiment, the specific connection structure between the auxiliary support structure 11 and the lathe flange 12 is as follows: the back of the lathe flange 12 is provided with a mounting groove 121, the mounting groove 121 is provided with a mounting hole 122 which axially penetrates to the front of the lathe flange 12, the supporting body 111 is embedded in the mounting groove 121, and the supporting pin 112 is placed in the mounting hole 122. The above structure reliably ensures stable connection between the support body 111 and the lathe flange 12, and leaves sufficient space for the support pins 112 to move inside the lathe flange 12.

Further, as shown in fig. 5, in the present embodiment, a limiting step 123 is provided between the mounting groove 121 and the mounting hole 122, the bottom end of the support pin 112 is provided with an expanded diameter portion 1121, and the limiting step 123 and the expanded diameter portion 1121 cooperate to be adapted to limit the range of upward movement of the support pin 112 in the axial direction. Since the support pin 112 is moved upward in the axial direction by the elastic member 113, the above structure is provided to prevent the support pin 112 from being separated from the lathe flange 12 during the upward movement in the axial direction.

Further, in the present embodiment, a gap is provided between the side wall of the support pin 112 and the inner wall of the mounting hole 122, and the gap is provided within two wires. The supporting pin 112 and the mounting hole 122 are arranged to be loose, so that the resistance to which the supporting pin 112 is subjected can be effectively reduced, the supporting pin 112 can be moved more smoothly, the provided support is more stable, the gap is arranged between two wires (0.02 mm), and the product failure caused by the fact that aluminum scraps are clamped in the supporting pin 112 can be avoided while the fixed-point precision of the supporting pin 112 is effectively ensured.

As shown in fig. 5 and 6, in the present embodiment, the auxiliary supporting structure 11 further includes a locking member 114, the locking member 114 is adapted to move in a radial direction of the supporting pin 112, and an end portion of the locking member 114 is adapted to abut against a side wall of the supporting pin 112 and limit the axial movement of the supporting pin 112. The inventor of the present application found that if only the elastic member 113 is adopted, the supporting force and the supporting stability may be poor, and in this regard, the inventor of the present application adds the locking member 114, and when the supporting pin 112 reaches the supporting position under the action of the elastic member 113 to abut against the workpiece 2, the user can screw the locking member 114, thereby locking the supporting pin 112 and providing a stable and strong supporting force for the workpiece 2.

Further, in the present embodiment, since the support body 111 is provided in the mounting groove 121 at the back of the lathe flange 12, the support pin 112 is prevented from being in the mounting hole 122, and thus, the specific mounting structure of the locking member 114 is: retaining member 114 is mounted on a side wall of lathe flange 12 and an end of retaining member 114 is adapted to be inserted into mounting hole 122 by radial movement against a side wall of support pin 112. The structure is simple and stable, and the operation is convenient and quick.

Further, in the present embodiment, the auxiliary support structure 11 is provided at the edge of the lathe flange 12. The reason for providing the above structure is that: the locking member 114 is mounted on the lathe flange 12 and is required to be inserted into the mounting hole 122 in the radial direction to achieve locking, so that the support main body 111 and the support pin 112 are prevented from being positioned at the edge of the lathe flange 12, and the radial movement distance of the locking member 114 can be effectively reduced, so that the operation is more convenient and quick.

Further, as shown in fig. 7 and 8, in the present embodiment, a reinforcing head 1141 is provided at the top end of the locking member 114, and a plurality of limiting protrusions 1142 having a truncated cone structure are provided on the reinforcing head 1141. The above structure serves to further increase the limiting effect of the locking member 114 on the support pin 112, thereby achieving reliable locking of the support pin 112.

It should be noted that there are many specific ways of inserting, for example, in another embodiment, the supporting body 111 may be inserted on the front surface of the flange 12 of the lathe, and the top end of the supporting body 111 may be elongated appropriately, so as to provide a carrier for mounting the locking member 114; in yet another embodiment, the support body 111 is still disposed on the back of the lathe flange 12, but the support body 111 is not embedded within the lathe flange 12, only the support pins 112 are embedded within the lathe flange 12. The two embodiments described above differ from the preferred embodiment in that the longitudinal space requirements of the auxiliary support structure 11 are different, i.e. the above embodiments also have the effect of reducing the space requirements, but in particular the amount of reduction is different, and therefore what kind of embedding is used can be adjusted according to the actual production structure.

The working steps of the application are as follows:

the first step: the auxiliary support structure 11 is mounted in a corresponding position on the lathe flange 12.

And a second step of: the locking member 114 is released, so that the supporting pin 112 is lifted up to the point where the supporting point is required to abut against the workpiece 2 under the action of the elastic member 113.

And a third step of: the locking member 114 is rotated, and the limit protrusion 1142 on the fastening head 1141 will press against the side of the supporting pin 112, so as to provide stable and strong supporting force for the product.

In addition, this application structure is succinct easily understood, and all kinds of processing environment of adaptation that can be fine only regularly carry out simple and easy maintenance can, and specific maintenance mode is: 1. the surface of the product is subjected to rust prevention measures such as surface blackening treatment or paint brushing; 2. when the support pin 112 is first installed, used, removed and stored, the support pin needs to be oiled to ensure smooth sliding.

It should be noted that, the supporting pin 112 of the present application is replaceable so as to adjust the Z-direction height, and the corresponding change can be made according to the requirement generated by the actual processing so as to satisfy the matching of various similar products, and the elastic member 113 of the present application adopts a spring, which has the advantages of simple and stable structure, convenient manufacture and convenient installation, and of course, the elastic member 113 can also adopt parts such as plastic elastic pads. And, the core part that this application used is mostly standard part, and it is convenient to change, and the loss rate is low, and it is convenient to change, can not influence production rhythm almost when adjusting.

As shown in fig. 1-3, the present application further provides a workpiece support component 1, including the auxiliary support structure 11, as described above, and further including a lathe flange 12, a support column 13, and a fixture block 14.
