Description

TECHNICAL FIELD

[0001] The utility model relates to the field of part deformation correction frock, especially a part processing deformation correction device. BACKGROUND

[0002] Parts are seriously deformed due to thermal stress in the machining process, and the flatness and parallelism cannot meet the requirements, which generally need to be corrected by a correction mechanism. During the correction process, an operator needs to operate the correction mechanism to correct different positions of the part to be corrected, and the correction mechanism needs to exert a certain pressure on the part to be corrected to obtain relevant size data during the correction process. Therefore, the strength, hardness and volume of the correction mechanism need to meet the correction requirements, which makes the existing correction mechanism difficult to operate.

[0003] Therefore, the present application is proposed. UTILITY MODEL CONTENT

[0008] A sliding support member is arranged on one of the base and the sliding arm, and is used to contact the other one of the base and the sliding arm. The sliding support member comprises a receiving part in the sliding channel and a rolling member arranged in the receiving part. When the sliding arm slides relative to the base, the rolling member contacts the base or the correction table top. During the correction process of the correction device on the frame beam, the correction pressure of the correction device on the part drives the rolling member to disengage from the base or the correction table top.

[0010] Preferably, the slot of the T-shaped groove faces the correction table top, and the side of the frame beam opposite to the slot faces away from the correction table top. During the correction, the pressure applied to the frame beam is configured to be in a direction away from the correction table top.

[0011] Preferably, the base comprises a sliding rail arranged in the T-shaped groove, and the top surface of the sliding rail is used to contact the rolling member.

[0012] Preferably, the correction device is configured to slide relative to the beam in a second direction perpendicular to the first direction.

[0013] Preferably, the sliding support member comprises a connecting member, one end of which is connected to the sliding arm and the other end of which is the accommodating portion, the accommodating portion having an accommodating cavity accommodating the rolling member.

[0014] Preferably, the large end of the T-shaped groove is on the lower side, and the accommodating portion is arranged at the large end of the T-shaped groove, the accommodating portion being movable upward under the correction pressure and driving the rolling member away from the sliding rail, and being stopped from moving upward under the resistance of the end edge of the small end of the T-shaped groove.

[0018] In the above-mentioned scheme, the frame body for mounting and supporting the correction device is supported on the base through sliding, the frame body contacts the base or the correction table through the rolling member during sliding, thereby reducing the friction during sliding and facilitating the operation of the operator. During correction, the position of the rolling member away from the base, i.e. the contact with the base or the correction table is broken, under the pressure between the correction device and the part to be corrected, so that the rolling member will not be abraded and the service life of the correction equipment will not be reduced under a larger correction pressure.

In other embodiments, the slide rail can not be arranged, so that the rolling member 71 directly contacts the correction table 1.

[0033] Reference Figure 1 The frame body has two sliding arms 3 and a frame beam 4 between the two sliding arms 3, and the frame beam 4 is used for installing a correction device 5.

The two bases 2 are arranged at intervals, the two sliding arms 3 support the frame beam 4 therebetween, and the correction device 5 is movably arranged on the frame beam 4. Among them, the correction device 5 is arranged on the frame beam 4 in a sliding manner along the length direction of the frame beam 4. Therefore, the correction device 5 can move in the length direction of the frame beam 4, the two sliding arms 3 slide in a direction perpendicular to the first direction in which the base 2 extends, so that the correction device 5 can correct the to-be-corrected part 6 in two mutually perpendicular directions. That is, the XY coordinate movement adjustment formed by the base 2 and the frame beam 4 is used for rapid positioning. Among them, the correction device 5 comprises a support, a nut and a screw rod, the screw rod is connected to the support through the nut and slides on the frame beam 4 through the support. Among them, the sliding mechanism of the support between the frame beams 4 can be a linear guide rail, a ball screw and a non-standard linear slide rail structure and the like.

[0034] The screw thread of the screw rod rotates to work on the to-be-corrected part 6 to transmit pressure and collect data, then the two double data of pressure and size are compared and referenced to achieve rapid correction. The to-be-corrected part 6 is in a long strip shape, a rectangle or a square structure. That is, the downward vertical screw rod is in pressure contact with the to-be-corrected part 6, the pressure between the screw rod and the to-be-corrected part 6 is adjusted, and the reaction force of the to-be-corrected part 6 on the screw rod is obtained through the detection module arranged between the screw rod, the screw rod and the nut or the nut and the frame beam to obtain the correction size. The detection module can be a scale, an electronic watch or a pressure detection module electrically connected to a computer device to display the pressure value and quickly determine the correction size.

The lower end of the T-shaped connecting portion is lifted by the correction pressure during correction, and is away from the position of the ball to disengage from the contact with the ball. Avoiding a large correction pressure from damaging the ball.
