Description

Technical Field

[0001] This invention relates to the field of nuclear power processing technology, and in particular to an adjustment fixture for quick tool installation and its usage method. Background Technology

[0002] In the machining process of nuclear power equipment, many types of cutting tools are frequently changed and used. Because nuclear power equipment is large equipment, the cutting tools used are large and heavy. It takes three people to complete the installation of the cutting tools (two people lift the cutting tool into place, and one person operates the cutting tool on the CNC panel). There are problems such as uneven force and incomplete cutting tool placement, which may require multiple installations. This not only reduces work efficiency but also poses safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustment fixture for quick tool installation and its usage method, which solves the problem of difficulty in adjusting the orientation during tool installation, improves work efficiency, and saves labor costs.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] An adjustment fixture for quick tool mounting includes:

[0006] Movable lifting mechanism;

[0007] An adjustment mechanism, installed on the lifting mechanism, includes a first half-ring, a second half-ring, a third half-ring, and a fourth half-ring concentrically arranged in a horizontal direction. The first half-ring is used to support the tool to be installed. The first half-ring and the second half-ring are connected by a first concentric shaft. The second half-ring and the third half-ring are connected by a second concentric shaft. The first concentric shaft is perpendicular to the second concentric shaft. The third half-ring and the fourth half-ring are rotatably connected. The fourth half-ring is rotatably connected to the lifting mechanism by an eccentric shaft arranged in a horizontal direction. The handle is connected to the third half-ring and is used to drive the third half-ring to rotate around the central axis of the fourth half-ring.

[0008] The locking mechanism, connected to the adjusting mechanism, has a locked state and an unlocked state. When it is in the unlocked state, the fourth half-ring can rotate around the eccentric axis. When it is in the locked state, the fourth half-ring cannot rotate around the eccentric axis.

[0009] Optionally, the adjustment mechanism further includes: a fastener, wherein the inner side of the fourth half-ring is provided with a semi-annular step extending downward from the edge of the upper surface, the outer side of the third half-ring has a connecting portion adapted to the semi-annular step, the connecting portion overlaps on the semi-annular step, and the fastener is fixed to the upper surface of the fourth half-ring and forms a receiving space adapted to the connecting portion with the semi-annular step.

[0010] Optionally, the locking mechanism includes: a control handle, a transmission line, a latch, an elastic element, a gear, and a fixing element. The fixing element is fixed on the fourth half-ring, the gear is mounted on the end of the eccentric shaft, the root of the latch is rotatably connected to the fixing element, and the head of the latch abuts against the gear. One end of the elastic element is fixed to the fixing element, and the other end is connected to the middle of the latch near its root. One end of the transmission line is connected to the middle of the latch near its head, and the other end is connected to the control handle.

[0011] Optionally, the control handle is fixed to the handle.

[0012] Optionally, the upper surface of the first semi-ring is provided with a positioning structure adapted to the shank of the tool to be installed.

[0014] Optionally, the lifting mechanism is a hydraulic trolley.

[0015] Optionally, the first, second, third, and fourth semi-rings are made of carbon steel.

[0016] A method of using an adjustment fixture for quick tool mounting as described in any of the above claims includes the following steps:

[0017] Place the cutting tool to be installed with the blade tip facing down and the handle in the first half-ring;

[0018] Move and raise / lower the lifting mechanism to adjust the approximate height and position of the tool so that it is roughly aligned with the machine tool tool mounting part;

[0019] By rotating the third half-ring with the handle, the circumferential angle of the tool is adjusted so that it is aligned with the tool mounting part of the machine tool;

[0020] Control the unlocking mechanism to adjust the rotation angle of the fourth half-ring, thereby adjusting the tool height so that the tool can be smoothly loaded into the machine tool.

[0021] Optionally, the method further includes:

[0022] Control the unlocking mechanism to adjust the rotation angle of the fourth half-ring so that it is in a near-horizontal state.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] To address the problems encountered in tool installation in existing technologies, this invention designs a large tool adjustment auxiliary fixture suitable for installing tools vertically. During tool installation, the tool is first placed into the tool adjustment fixture, and then the tool is raised to the specified height and angle. Due to gravity, the tool remains vertical. The four ring supports of the fixture provide multiple degrees of freedom for the tool to be fine-tuned by the operator, allowing for tool installation by a single operator, thus improving work efficiency and safety.

[0035] Combination Figures 1 to 6 As shown, the present invention provides an adjustment fixture for quick installation of cutting tools, comprising: a movable lifting mechanism 100, an adjustment mechanism 200, and a locking mechanism 300.

[0036] like Figure 1As shown, the lifting mechanism 100 can be a modified hydraulic vehicle, whose main function is to provide support for the entire tooling and enable the tooling to move in the horizontal direction and make approximate adjustments in the vertical direction.

[0037] The adjustment mechanism 200 is mounted on the lifting mechanism 100 and includes a handle 250 and a first half-ring 210, a second half-ring 220, a third half-ring 230, and a fourth half-ring 240 arranged concentrically in the horizontal direction. The first half-ring 210 is used to support the tool 400 to be installed. The first half-ring 210 and the second half-ring 220 are connected by a first concentric shaft 211. The second half-ring 220 and the third half-ring 230 are connected by a second concentric shaft 221. The first concentric shaft 211 is perpendicular to the second concentric shaft 221. The third half-ring 230 and the fourth half-ring 240 are rotatably connected. The fourth half-ring 240 is rotatably connected to the lifting mechanism 100 by an eccentric shaft 241 arranged in the horizontal direction. The handle 250 is connected to the third half-ring 230 and is used to drive the third half-ring 230 to rotate around the central axis of the fourth half-ring 240.

[0038] In this embodiment, the four semi-rings form a rotating structure similar to that in a gyroscope. The first semi-ring 210 and the second semi-ring 220 are connected by a first concentric axis 211, and the second semi-ring 220 and the third semi-ring 230 are connected by a second concentric axis 221. The first concentric axis 211 and the second concentric axis 221 are both horizontal and perpendicular to each other. The third semi-ring 230 is concentric with the fourth semi-ring 240 and can rotate around the central axis of the fourth semi-ring 240. The first semi-ring located at the center is connected to the cutter 400. The center of the cutter 400 coincides with the center of the first semi-ring 210. Thus, the cutter 400 can rotate freely in the vertical direction. Due to gravity, the cutter head always points downward, while ensuring that the center of the cutter 400 is always located at the center of the four semi-rings.

[0039] The handle 250 is connected to the third half-ring 230. By moving the handle 250, the rotation angle of the third half-ring 230 can be adjusted, thereby fine-tuning the circumferential angle of the tool 400. The fourth half-ring 240 is eccentrically connected to the lifting mechanism 100. When the fourth half-ring 400 rotates, the tool 400 at the center can achieve fine-tuning of its vertical position.

[0040] The upper surface of the first semi-ring 210 is provided with a positioning structure 212 that is adapted to the shank of the tool 400 to be installed. The positioning structure 212 enables rapid positioning and fixing of the tool. For example, if the shank of the tool 400 has two slots in the circumferential direction, the positioning structure 212 is a protrusion adapted to the slots.

[0041] like Figure 4As shown, the adjustment mechanism 200 further includes a fastener 260. The inner side of the fourth semi-ring 240 has a semi-annular step 242 extending downwards from the edge of its upper surface. The outer side of the third semi-ring 230 has a connecting portion 231 adapted to the semi-annular step. The connecting portion 231 overlaps the semi-annular step 242. The fastener 260 is fixed to the upper surface of the fourth semi-ring 240 and forms a receiving space adapted to the connecting portion 231 with the semi-annular step 242. The fastener 260 can be fixed to the upper surface of the fourth semi-ring 240 by bolts. The fastener 260 and the annular step 242 define the receiving space of the connecting portion 231. The fastener 260 can be a single semi-circular part or can include multiple arc-shaped parts; no limitation is made here. The fastener 260 and the connecting portion 231 are not tightly fitted, but have a certain gap to allow the connecting portion 231 to move within the receiving space.

[0042] In this embodiment, the first half-ring 210, the second half-ring 220, the third half-ring 230 and the fourth half-ring 240 are made of carbon steel to improve the strength of the four ring seats.

[0043] The locking mechanism 300 is mounted on the adjusting mechanism 200 and has a locked state and an unlocked state. When it is in the unlocked state, the fourth half ring 240 can rotate around the eccentric shaft 241. When it is in the locked state, the fourth half ring 240 cannot rotate around the eccentric shaft 241.

[0044] Specifically, such as Figure 2 and Figure 3As shown, the locking mechanism 300 includes: a control handle 310, a transmission line 320, a locking tongue 330, an elastic element 340, a gear 350, and a fixing element 360. The fixing element 360 is fixed to the fourth half-ring 240. The gear 350 is mounted on the end of the eccentric shaft 241. The root of the locking tongue 330 is rotatably connected to the fixing element 360, and its head abuts against the gear 350. One end of the elastic element 340 is fixed to the fixing element 360, and the other end is connected to the middle of the locking tongue 340 near its root. One end of the transmission line 320 is connected to the middle of the locking tongue 340 near its head, and the other end is connected to the control handle 310. The rotational freedom of the fourth half-ring 240 can be controlled by the control handle 310. When the control handle 310 is squeezed, the transmission line 320 stretches, causing the locking tongue 330 to move away from the gear 350. The locking tongue 330 compresses the elastic element 340, releasing the freedom of the gear 350, allowing it to rotate freely. The locking mechanism 300 is in the unlocked state, and the fourth half-ring 240 can rotate around the eccentric shaft 241. However, due to the large weight of the cutter 400, the cutter 400 descends, causing the fourth half-ring 240 to rotate around the eccentric shaft 241 (in...). Figure 1 (Viewed from left to right, the fourth half-ring 240 rotates counterclockwise); when the cutter 400 descends to the appropriate position, the control handle 310 is released, the transmission line 320 is loosened, and due to the rebound of the elastic element 340, the locking tongue 330 springs back to engage the gear 350, the locking mechanism 300 is in a locked state, and the fourth half-ring 240 cannot rotate. The third half-ring 230 can still rotate circumferentially within the fourth half-ring 240.

[0045] For ease of operation, the control handle 310 can be fixed to the handle 250. In other embodiments, the control handle 310 can also be fixed to the lifting mechanism 100, for example, to the handrail of a hydraulic vehicle.

[0046] There may be two locking mechanisms 300, which are respectively installed on the eccentric shafts 241 on both sides of the fourth semi-ring 240. Alternatively, there may be only one locking mechanism 300, which is installed on the eccentric shaft 241 on one side of the fourth semi-ring 240.

[0047] The present invention also provides a method for using the above-mentioned adjustment fixture for quick tool installation, comprising the following steps:

[0048] S1, place the tool to be installed with the blade tip facing down and the handle in the first half-ring.

[0049] Specifically, the slot on the handle is aligned with the protrusion on the first half-ring to achieve the positioning and fixation of the handle.

[0050] S2, move and raise / lower the lifting mechanism to adjust the approximate height and position of the tool so that it is roughly aligned with the machine tool tool mounting part.

[0051] Specifically, the hydraulic carriage is pushed to the machine tool mounting section so that the cutting tool is roughly facing the machine tool mounting section. The height of the adjusting mechanism is then adjusted by the lifting mechanism to be roughly aligned with the machine tool mounting section.

[0052] S3, rotate the third half-ring using the handle to adjust the circumferential angle of the tool so that it is aligned with the machine tool mounting part.

[0053] This step is used to align the tool with the tool mounting part in the circumferential angle. During the adjustment process in this step, the first and second half rings act as gyroscopes, so that the tool tip is always vertically downward.

[0054] S4. Control the unlocking mechanism to adjust the rotation angle of the fourth half-ring, thereby adjusting the tool height so that the tool can be smoothly loaded into the machine tool.

[0055] After the tool angle is suitable for installation, control the rotation angle of the fourth half ring by squeezing and releasing the control handle, so that the tool drops one tooth groove height each time. Observe whether the tool is aligned with the tool mounting part of the machine tool in terms of height. If it is aligned, the tool can be successfully installed into the machine tool.

[0056] In addition, the method of use also includes:

[0057] S5, control the unlocking mechanism to adjust the rotation angle of the fourth half-ring so that it is in a near-horizontal state.

[0058] After the tool is installed, squeeze the control handle to unlock the mechanism, rotate the fourth half-ring to near-horizontal, and then release the control handle to maintain this near-horizontal position. Lower the hydraulic trolley and place the handle at any flat end of the lower part of the hydraulic trolley's handle.

[0059] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
