Description

Technical Field

[0001] The invention relates to a universal positioning tool. Background Art

[0002] In mechanical processing, tooling is often used to fix the position of parts and install them on the machine. However, the design, production and use of tooling often have the following problems: 1. There is an error between the designed tooling position and the designed machine position, and the tooling needs to be reworked; 2. The shape and structure of the machine are relatively complex, and the positioning of parts is greatly restricted by space, which makes it inconvenient for personnel to operate and difficult to design tooling; 3. When parts are modified, the positioning position of parts changes, and tooling needs to be redesigned and produced, which increases manpower, material resources and time; therefore, it is very important to have a tooling that is highly versatile, lightweight and flexible.

[0021] Reference Figures 1 to 4 A universal positioning tool comprises a base assembly 1 which moves horizontally, a column 2 which is vertically arranged on the surface of the base assembly 1, and a slider 24 which moves up and down along the column 2. The slider 24 is movably connected to a support arm assembly 3. As can be seen from the figure, the base assembly 1 has two vertical translation directions, and together with the column 2, an XYZ three-axis motion platform is formed. The parts installed on the support arm assembly 3 can move in translation through the base assembly 1 and the column 2.

[0022] The support arm assembly 3 includes a rotating shaft 4, an intermediate rod 5, a swing rod 6 and a universal support arm 7 connected to the parts at one end. One end of the rotating shaft 4 passes through the inner hole of the slider 24 on the column 2 and rotates around the inner hole 241. The rotating shaft 4 serves as the base of the support arm assembly 3. Rotating the rotating shaft 4 causes the entire support arm assembly 3 to rotate. The other end of the rotating shaft 4 is hinged to one end of the intermediate rod 5 through a hinge seat a41. The threaded hole a42 provided on the side wall of the hinge seat a41 is perpendicular to and deviates from the hinge axis a43. The locking stud a44 passes through the threaded hole a42 and abuts against the intermediate rod 5. Adjust the swing angle of the middle rod 5. The other end of the middle rod 5 is hinged to the hinge seat b61 at one end of the swing rod 6. The threaded hole b62 set on the side wall of the hinge seat b61 is vertical and deviates from the hinge axis b63. ​​The locking stud b64 passes through the threaded hole b62 and abuts the middle rod 5. The swing angle of the swing rod 6 can be adjusted. The other end of the swing rod 6 is connected to the universal support arm 7. The end of the universal support arm 7 is connected to the parts. The position can be flexibly adjusted through the universal support arm 7 to extend into various complex machine environments for positioning and installation to avoid interference with the internal mechanism of the machine. After completing the work, all parts on the support arm assembly 3 can be tightened and removed from the column 2 together with the slider 24. The disassembled support arm assembly 3 will maintain the state of the assembled parts and will not change. Replace with a new support arm assembly. When the parts need to be assembled again, the previous support arm assembly 3 can be directly installed and reused without adjustment.

[0023] Through the above position adjustment structure, the relative position of the part and the machine can be moved through the base assembly 1 and the column 2, and the rotating shaft 4 can be rotated and the swing angle of the intermediate rod 5 and the swing rod 6 can be adjusted by screwing the locking studs a44 and b64 to change the positioning angle of the part, so that the part can be positioned and installed with the machine from multiple directions and angles. When the product needs to be replaced or the positioning position of the part needs to be temporarily changed, it is only necessary to readjust the position of the components of the base assembly, the column and the support arm assembly 3 so that the tooling meets the new positioning, and there is no need to redesign and modify the new tooling, which is convenient and practical. And through the flexible movement characteristics of multiple directions and angles, a dial indicator can be installed at the end of the support arm assembly 3, which is very convenient for measuring equipment and machines with complex structures.

[0024] Reference Figure 4 The rotating shaft 4 of the present invention is engraved with a dividing line on the circumferential surface of one end thereof that penetrates into the inner hole 241 of the slider, and at the same time, a marking line is engraved on the end face of the inner hole 241 of the slider. When the rotating shaft 4 is rotated, the dividing line moves relative to the marking line, and it can be known how many degrees the rotating shaft 4 has rotated relative to the original position, which can be used to assist in measuring the position of parts; when the inner hole 241 of the slider 24 is a countersunk hole, one end of the rotating shaft 4 is inserted into the countersunk hole, and the locking stud c242 passes through the small hole in the countersunk hole and cooperates with the threaded hole c45 in the rotating shaft 4. The locking stud c242 axially locks and fixes the position of the rotating shaft 4 in the countersunk hole 241 of the slider, and the operation is simple and easy.

[0025] Preferably, the front and rear parts of the intermediate rod 5 of the present invention are respectively provided with a hinge hole a51 and a hinge hole b52 which are perpendicular to each other. The hinge hole a51 is hinged to the hinge shaft a43 on the rotating shaft 4, and the hinge hole b52 is hinged to the hinge shaft b63 on the swing rod, so that the swing direction of the rotating shaft 4 is perpendicular to the swing direction of the swing rod 6, thereby increasing the angle change of the support arm assembly 3, which is beneficial to the angle adjustment of the tooling at different joint positions.

[0026] In order to further increase the ability of the support arm assembly 3 to adjust the position at the end joint, the universal support arm 7 is threadedly connected to the swing rod 6 through a universal ball seat 71 at one end and connects the parts through a support rod 72 at the other end. The support rod 72 is composed of two hinged support arms. A locking handwheel 73 is provided at the hinge of the two support arms. When it is necessary to adjust the spatial position of the end parts, the posture of the support rod 72 is adjusted to a suitable position and the locking handwheel 73 is turned to fix the position of the end parts, which is convenient and quick.

[0027] Reference Figure 3 The base assembly 1 and the column 2 of the present invention both use a screw-nut transmission mechanism, the two ends of the first screw 14 are connected to the upper screw seat of the middle seat 12, the first nut 15 is sleeved on the first screw 14 and fixed to the bottom surface of the upper seat 11, and the first screw 14 is rotated to make the first nut 15 drive the upper seat 11 to move linearly, the two ends of the second screw 16 are connected to the lower screw seat of the middle seat 12, the second nut 17 is sleeved on the second screw 16 and fixed to the upper surface of the lower seat 13, and the second screw 16 is rotated to make the second nut 17 drive the middle seat 12 moves linearly with the upper seat 11. At the same time, since the first screw rod 14 and the second screw rod 16 are perpendicular to each other, the moving direction of the upper seat 11 and the moving direction of the middle seat 12 are also perpendicular to each other, so that the parts can be moved in two perpendicular directions. The vertical screw rod 22 and the guide rod 21 are correspondingly inserted into two mutually parallel threaded holes and through holes in the nut seat 25 and are vertically plugged into the surface of the base assembly 1. By rotating the turntable 23, the vertical screw rod 22 drives the nut seat 25 to move up and down, so that the parts can be moved in the third direction. The structure is simple and the operation is convenient.

[0028] The present invention is different from previous tooling in that it is flexible, easy to move and adjust, and adaptable to various machines with complex structures. When the positioning position of parts is changed or the product is replaced, the tooling does not need to be redesigned, manufactured or reworked, thus saving a lot of manufacturing costs.
