Description

Technical Field

[0001] The present invention relates to the field of machining, and more particularly to an optimized machining auxiliary positioning support device. Background Art

[0002] With the development of economy, environmental pollution is becoming more and more serious. In order to solve the problem of environmental pollution, the country vigorously promotes the development of new energy industry. As an important part of new energy industry, nuclear power industry is increasingly valued by the country. Transfer equipment is an important power device for fuel replacement in nuclear power reactor. In transfer equipment, the processing accuracy of thin-walled box parts is required to be high; in the machining process, the support of thin-walled box parts is particularly important. Since thin-walled box parts have a large depth and a small inner cavity height, it is difficult for general support devices to meet the expected support requirements.

[0003] At present, the support devices for processing thin-walled box parts mainly include pads, hydraulic jacks or lock nut screw devices. When pads are used for support, it is difficult to find pads that are consistent with the height of the inner cavity of the thin-walled box for support, and the cavity is deep and small in height, so it is difficult to put the pads in the specified position, which brings inconvenience to the support. When a hydraulic jack is used for support, the cavity is deep and small in height, and the rocker of the hydraulic jack cannot be shaken up and down well. It is even impossible to shake the rocker up and down because the height is too small, which brings inconvenience to the support. When a nut screw device is used, the cavity is deep and small in height, and the nut screw device cannot be touched, and the nut screw device cannot be adjusted, which brings inconvenience to the support.

[0004] In addition, the above three support devices are rough support, and the positioning accuracy is not high. For thin-walled boxes with high precision requirements, during the support process, it is easy to deform the box due to excessive support force or too little support force, which cannot guarantee processing accuracy and leads to low production efficiency because the force is difficult to control. Summary of the invention

[0082] like Fig. 9 As shown, the support device 1000 also includes a pressure measuring device 500, which is arranged on the upper surface of the second support member 200. The pressure measuring device 500 is used to set a preset pressure value.

[0083] It should be noted that the supporting device provided in the present application is mainly used to support thin-walled box parts. The working state of the supporting device provided in the present application will be introduced below.

[0084] Combination Figure 1-Figure 9 As shown, before the support device 1000 is used, the telescopic rod 403 is placed in the U-shaped groove 107 and the U-shaped opening 204 and is in a retracted and vertical state.

[0085] When the supporting device 1000 is used,

[0086] First, the telescopic rod 403 is rotated from a vertical state to a horizontal state, and at the same time, the primary rod 431, the secondary rod 432, the tertiary rod 433, the quadruple rod 434 and the quintuple rod 435 are stretched according to the depth of the thin-walled box cavity, so as to adjust the total length of the telescopic rod 403.

[0087] This embodiment facilitates accurate processing of thin-walled boxes with large cavity depth and small height by stretching and contracting the total length of the telescopic rod 403.

[0088] Second, a preset pressure value is set in the pressure measuring device 500 .

[0089] Third, place the supporting device 1000 into the cavity of the thin-walled box to be supported, adjust the position of the device in the cavity, pull one of the two traction lines in the telescopic rod 403, and adjust the swing position of the lever 401 by adjusting the swing position of the rotating member 42 until it contacts one of the two limit posts 43.

[0090] Fourth, by swinging the telescopic rod 403 left and right, the lever 401 is driven to rotate, the lever 401 drives the second gear 304 to rotate forward, the second gear 304 drives the first gear 303 to rotate forward, and the first gear 303 drives the lead screw 301 to move upward, so that the second support member 200 continuously rises under the rotation of the lead screw 301. When the upper surface of the second support member 200 contacts the cavity surface of the thin-walled box body, and the pressure value of the pressure measuring device 500 reaches the preset pressure value, the pressure measuring device 500 will alarm. At this time, stop swinging the telescopic rod 403, the pressure measuring device 500 will automatically stop the alarm after 3-5 seconds, and the technicians can process the thin-walled box body parts.

[0091] This embodiment provides a liftable support device 1000, which is conducive to supporting thin-walled boxes of various heights. In addition, by arranging a pressure measuring device 500 on the upper surface of the second support member 200, it is possible to avoid the problem that when the thin-walled box is supported by the support device 1000, the box is deformed due to excessive support force, or the processing accuracy cannot be guaranteed due to insufficient support force.

[0092] Fifth, after the processing of thin-walled box parts is completed, the supporting device 1000 needs to be removed, and the swing position of the lever 401 is adjusted by pulling the other of the two traction lines in the telescopic rod 403 and adjusting the swing position of the rotating member 42 until it contacts the other of the two limit posts 43.

[0093] Sixth, by swinging the telescopic rod 403 left and right, the lever 401 is driven to rotate, the lever 401 drives the second gear 304 to rotate in the opposite direction, the second gear 304 drives the first gear 303 to rotate in the opposite direction, and the first gear 303 drives the lead screw 301 to move downward, so that the second support member 200 continuously descends under the rotation of the lead screw 301. When the slider 104 of the first support member 100 is in the strip-shaped slide groove 203 of the second support member 200 and touches the lower surface of the support plate a 201 of the second support member 200, the telescopic rod 403 stops swinging.

[0094] Finally, the supporting device 1000 is taken out from the cavity of the thin-walled box, and the primary rod 431, the secondary rod 432, the tertiary rod 433, the quadruple rod 434 and the quintuple rod 435 are retracted to adjust the total length of the telescopic rod 403. Then, the telescopic rod 403 is rotated from a horizontal state to a vertical state, so that the telescopic rod 403 is placed in the U-shaped groove 107 and the U-shaped opening 204.

[0095] It should be noted that, in other embodiments, the driving device may be a motor, etc., which is not particularly limited herein.

[0096] The technical effect of the present invention is to provide a lifting support device, which is conducive to supporting thin-walled boxes of various heights. When the support device is used for support, the driving component drives the transmission component to rotate, and the second support member realizes up and down lifting movement under the action of the transmission component, and a pressure measuring device is arranged on the upper surface of the second support member, so as to accurately support the thin-walled box, avoid deformation of the box, and ensure the processing accuracy of the box. The driving component of the present application has a telescopic rod, and by stretching and contracting the total length of the telescopic rod, it is conducive to the accurate processing of thin-walled boxes with a large cavity depth and a small height.
