Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic linkage four-jaw chuck jaws of lathes, in particular to a hydraulic four-jaw jaw correction tool for lathes. Background Art

[0002] Mechanical production is inseparable from mechanical processing. General mechanical parts, especially high-precision mechanical parts, are produced and processed by lathes. Lathes are divided into ordinary lathes and CNC lathes. During mechanical processing, the tool to be processed needs to be clamped and positioned by means of jaws. The jaws are the most important components in mechanical processing. The jaws are divided into soft jaws and hard jaws. Generally, lathes use hard jaws to turn bars, blanks, etc. The clamping is labor-intensive. Soft jaws can reduce damage to parts and improve coaxiality, playing an important role in finishing and secondary clamping.

[0003] At present, the existing jaw trimmer is fixed on the four-jaw chuck at four points, which is troublesome and the process is cumbersome. Sometimes it is often difficult to find the soft jaw clamping diameter you want. During operation, the operator cannot match the soft jaws at once and needs to make multiple adjustments before the installation is completed. Moreover, during the turning process, the jaw trimmer is easy to slip off the four-jaw chuck, causing damage to the lathe equipment or even personal injury. Utility Model Content

Sometimes the operator cannot find the soft jaw clamping diameter he wants. During operation, the operator cannot match the soft jaw at once and needs to make multiple adjustments before the installation is completed. Moreover, during the turning process, the jaw trimmer is easy to slip on the four-jaw chuck, causing damage to the lathe equipment and even personal injury.

[0008] Preferred technical solution 2: An inner resistance block is provided at the end of the driving screw, and the inner resistance block is rotatably connected to the end of the driving screw via a rotating connection block.

[0009] Preferred technical solution three: the side contact blocks are obliquely arranged on both sides of the middle contact block, and the side contact blocks on the left and right sides of the middle contact block are inclined in opposite directions.

[0025] See also Figure 1-4 A hydraulic four-jaw clamping correction tool for a lathe comprises a four-jaw correction main body 1, side sockets 4 are symmetrically opened around the four-jaw correction main body 1, an adjusting screw 2 is inserted into the side socket 4, a locking nut 3 is sleeved on the rod of the adjusting screw 2, the end of the adjusting screw 2 passes through the side socket 4 and extends to the inside of the four-jaw correction main body 1, a replaceable interference component 5 is provided at the end of the adjusting screw 2, and four correction auxiliary components 6 are also evenly and symmetrically arranged on the four-jaw correction main body 1.

[0026] The replacement interference component 5 includes a mounting screw hole 501 opened at the end of the adjusting screw 2, a screw contact head 502 is rotatably inserted into the mounting screw hole 501, a middle contact block 503 is provided at the end of the screw contact head 502, and several side contact blocks 504 are symmetrically provided on the left and right sides of the middle contact block 503.

[0027] The correction auxiliary component 6 includes an inner wall groove 601 opened around the inner wall of the four-claw correction body 1, and the inner wall of the inner wall groove 601 is provided with a driving screw hole 602. A driving screw 603 is rotatably inserted in the driving screw hole 602, and an inner resistance block 604 is provided at the end of the driving screw 603. The inner resistance block 604 is rotatably connected to the end of the driving screw 603 through a rotating connecting block 605.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that the side contact blocks 504 are arranged obliquely on both sides of the middle contact block 503, and the side contact blocks 504 on the left and right sides of the middle contact block 503 are inclined in opposite directions.

[0029] When the screw contact head 502 contacts the tool under the drive of the adjusting screw 2, the friction force on the tool surface can be increased.

[0030] Embodiment 3: The difference between this embodiment and embodiment 1 is that the depth of the inner wall groove 601 is greater than the length of the inner side abutment block 604 .

[0031] This allows the inner resistance block 604 to be more conveniently retracted into the inner wall groove 601, avoiding affecting the placement of the tool by the four-claw correction body 1.

[0032] Embodiment 4: The difference between this embodiment and embodiment 1 is that the surface of the inner contact block 604 is provided with anti-slip grooves for increasing friction.

[0033] The inner contact block 604 is effectively prevented from slipping when contacting the tool inside the four-claw correction body 1.

[0034] In this embodiment, since the existing jaw trimmer is fixed on the four-jaw chuck at four points, it is troublesome and the process is cumbersome. Sometimes, it is often difficult to find the soft jaw clamping diameter that the operator wants. During operation, the operator cannot match the soft jaws at once and needs to make multiple adjustments before the installation is completed. In addition, during the turning process, the jaw trimmer is prone to slipping off the four-jaw chuck, causing damage to the lathe equipment or even personal injury.

[0035] To sum up, in the specific implementation, the device is first placed in the four-jaw jaws of the lathe, the jaws are received to the same size value, the adjusting screw 2 is aligned with the corresponding jaws, the adjusting screw 2 is rotated outward until it hits the jaws, and then the jaws are clamped, and then the locking nut 3 is rotated to the adjustment surface and tightened to fix the device and the jaws, and finally the four-jaw chuck is rotated, and the jaws of the four-jaw chuck are corrected by the tool to improve the accuracy of the jaws. By adjusting the telescopic length of the adjusting screw 2, jaw correction tools of different sizes can be obtained, which saves the number of jaw correction tools and overcomes the defects of the existing technology that the jaw repairer has a small scope of application, cannot adjust the accuracy of the jaws or has low jaw adjustment accuracy.

[0036] The tool is characterized in that the required clamps of different sizes can be realized by adjusting the telescopic length of the adjusting screw 2, thereby saving the number of clamps.

[0037] The replacement abutment assembly 5 provided at the end of the adjusting screw 2 can be effectively replaced, so that the end of the surface adjusting screw 2 becomes smooth due to long-term repeated use, and may slip when clamping the tool surface.

[0038] The correction auxiliary component 6 is arranged on the side of the adjustment screw 2, wherein the inner resistance block 604 in the correction auxiliary component 6 can also push the inner resistance block 604 to the inner side of the four-claw correction body 1 when the user rotates the driving screw 603, thereby further strengthening the fixation of the side of the tool that is fixed by the adjustment screw 2, thereby effectively improving the stability of the tool.
