Referring to fig. 1 to 4, the present invention provides an efficient flatness-ensuring lathe fixture 100 for positioning and clamping a casting 200 to be processed. The efficient flatness-ensuring lathe jig 100 includes a base 10, a positioning device 20, and a clamping device 30.
The base 10 includes a bottom wall 11 and a cover 12 assembled with the bottom wall 11. The cover 12 and the bottom wall 11 together enclose a receiving space (not shown).
The cover 12 includes a top wall 121 disposed opposite to the bottom wall 11 at a distance, and a side wall 122 extending from a peripheral edge of the top wall 121 toward the bottom wall 11.
The positioning device 20 is fixedly arranged on the base 10 and used for positioning the casting 200 to be processed.
The clamping device 30 includes an auxiliary positioning seat 31 fixedly disposed on the base 10, a mounting seat 32 adjacent to the auxiliary positioning seat 31 and fixedly disposed on the base 10, and a pressing rod 33 mounted on the mounting seat 32. The positioning device 20 and the clamping device 30 are both disposed on a surface of the cover 12 or the bottom wall 11 away from the receiving space.
Wherein, the number of the positioning device 20 and the clamping device 30 is at least two. The number and the position of the positioning devices 20 are determined by the structure of the casting 200 to be processed.
Preferably, in this embodiment, an end surface of the positioning device 20 away from the base 10 and an end surface of the auxiliary positioning seat 31 away from the base 10 are located on the same plane, the number of the positioning devices 20 is two, and the number of the clamping devices 30 is three.

And the cross-sectional area of the support table 312 decreases along the extension of the support table 312.
The mounting seat 32 includes a main body 321 embedded in the top wall 121, a mounting plate 322 extending from the main body 321 in a direction away from the accommodating space, a through hole 323 sequentially passing through the main body 321 and the mounting plate 322, and a stopper 324 extending from the main body 321 into the through hole 323.
The pressing rod 33 includes a rod portion 331 sequentially penetrating through the mounting base 32 and the base 10 and extending into the accommodating space, a pressing head 332 disposed at an end of the rod portion 331 away from the accommodating space, a driving member (not shown) disposed in the accommodating space and connected to the rod portion 331, and an annular groove 334 disposed in the rod portion 331.
Preferably, in the present embodiment, the driving member is a cylinder.
The ram 332 is disposed opposite to the support table 312, and the driving member is configured to drive the ram 332 to move in a direction approaching to or away from the support table 312. In this way, since the cross-sectional area of the supporting platform 312 is gradually reduced along the extending direction thereof, that is, the surface area of the supporting platform 312 away from the body 311 is the smallest, so as to cooperate with the press head 332 to clamp the to-be-machined casting 200, thereby avoiding the large-area contact with the to-be-machined casting 200 in the prior art, and further avoiding the flatness change of the to-be-machined casting 200 caused by the over-pressing.
Specifically, the annular groove 334 is formed by recessing the outer wall of the stem 331 in the axial direction, the outer wall of the stem 331 abuts against the wall of the through hole 323, and the stopper 324 extends into the annular groove 334. Through mutually supporting the bumping post 324 with the annular groove 334, make the shank portion 331 all can take place rotatoryly at carry/return in-process, make the pressure head 332 turn to with the direction that the brace table 312 is just to/skew, be convenient for wait to process placing of foundry goods 200 before processing and accomplishing the back and take, avoided placing and taking the in-process to the physical damage that pressure head 332 caused.

In the working process of the lathe fixture 100 for ensuring high-efficiency flatness, when the driving member drives the rod portion 331 to carry, the first rod 3311 stops carrying after the ram 332 abuts against the casting 200 to be machined, and the second rod 3312 stops carrying after the unit length of the carrying continues.
Preferably, in the present embodiment, the unit length is 5cm. The clamping effect of the clamping device 30 is optimized on the premise that the pressure head 332 does not generate excessive pressure on the casting 200 to be machined.
Specifically, the first rod 3311 includes a first surface 3314 adjacent to the second rod 3312, a first recess 3315 recessed from the first surface 3314 in a direction away from the second rod 3312, and a second recess 3316 recessed from the bottom of the first recess 3315. The aperture of the second recess 3316 is 2 to 3 times the aperture of the first recess 3315.
The second rod 3312 comprises a second surface 3317 close to the first rod 3311, an extension rod 3318 extending from the second surface 3317 toward the first rod 3311, a stopper 3319 extending from the extension rod 3318 away from the second surface 3317 along a radial direction, and an elastic member 331X. The diameter of the extension rod 3318 is equal to the diameter of the first recess 3315, and the fixture block 3319 is disposed in the second recess 3316.
The elastic member 331X is disposed in the second recessed hole 3316, and two ends of the elastic member 331X are respectively abutted against the wall of the fixture block 3319 and the wall of the second recessed hole 3316. Preferably, in the present embodiment, the elastic member 331X is a high-strength spring.
In a normal state of the rod body 331, the elastic member 331X drives the first rod 3311 and the second rod 3312 to be in a close fit state, when the driving member drives the rod body 331 to move forward, the ram 332 gradually moves toward the support table 312 (the to-be-processed casting 200 is placed on the support table 312 and the auxiliary positioning seat 31) and gradually rotates toward a direction opposite to the support table 312, after the second extending portion 3322 abuts against the to-be-processed casting 200, the first rod 3311 stops moving forward, the driving member continues to drive the second rod 3312 to move forward, and the elastic member 331X compresses to realize and strengthen a clamping force between the second extending portion 3322 and the support table 312, so that the to-be-processed casting 200 is firmly fastened. Meanwhile, since the contact areas of the second extending portion 3322 and the supporting platform 312 with the casting 200 to be machined are small, the flatness of the casting 200 to be machined is not damaged.
