[0017] DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the drawings needed to be used in the embodiments or prior art description will be briefly introduced. Obviously, the drawings in the following description only represent some embodiments described in the present application, and for those skilled in the art, other drawings can also be obtained without creative labor on the basis of these drawings.

[0019] As Figures 1-6 ​The GCM fixed table and swing table tool shown in the figure, including a circular positioning disc 1, a plurality of guide grooves 11 are evenly arranged on the upper end surface of the positioning disc 1 along the radial direction thereof, and all the guide grooves 11 are uniformly distributed on the same concentric circle with the center of the positioning disc 1. Each guide groove 11 is provided with a set of adjusting mechanism 3, and each set of adjusting mechanism 3 is connected with a positioning seat 2. The number of positioning seats 2 is consistent with the number of guide grooves 11, and they are uniformly distributed on the concentric circle. The adjusting mechanism 3 is used to drive the positioning seat 2 connected with it to move accurately along the extension direction of the guide groove 11, that is, the radial direction of the positioning disc 1.

[0020] As shown in Figures 5-8 Each positioning seat 2 is mainly composed of a bottom plate 21 and an installation plate 22 vertically fixed to the bottom plate 21. The bottom plate 21 is connected with the driving end of the adjusting mechanism 3, and the side of the installation plate 22 close to the center of the positioning disc 1 is defined as the first installation surface for installing the fixed table 5. The side of the installation plate 22 away from the center of the positioning disc 1 is defined as the second installation surface for installing the swing table 6. The first installation surface and the second installation surface are both perpendicular to the radial direction of the positioning disc 1, thereby providing a stable and unified reference direction for the installation of the workpiece.

[0021] As shown in Figures 5-7 A first limiting groove 23 is machined on the first installation surface, and the width of the first limiting groove 23 is equal to the width of the fixed table 5, so that the fixed table 5 can be quickly and initially positioned and constrained in the horizontal plane. Two first limiting pins 231 and four first connecting holes 232 are arranged in the first limiting groove 23, and the first connecting holes 232 are threaded holes. During installation, the bottom of the fixed table 5 abuts against the first limiting pins 231 to realize accurate positioning in the vertical direction, and the bolts are inserted into the first connecting holes 232 and screwed into the installation holes of the fixed table 5 and tightened, thereby completing the installation of the fixed table 5.

[0022] A second limiting groove 24 is arranged on the second installation surface for accommodating and horizontally positioning the swing table 6. Two second limiting pins (not shown) and a second connecting hole 241 are arranged in the second limiting groove, and the second connecting hole 241 is a through hole. During installation, the bottom of the swing table 6 abuts against the second limiting pins to realize accurate positioning in the vertical direction, and the bolts are inserted into the second connecting hole 241 and screwed into the installation holes of the swing table 6 and tightened, thereby completing the installation of the swing table 6.

[0023] As shown in Figures 1-4As shown, the adjusting mechanism 3 includes a lead screw 31, one lead screw 31 is respectively installed in each guide groove 11, both ends of the lead screw 31 are fixed in both ends of the guide groove 11 through a bearing seat 32, and the axis of the lead screw 31 is parallel to the guide groove 11. A lead screw nut is fitted on the lead screw 31, a nut seat 33 is fixed on the nut, and the positioning seat 2 is connected with the nut seat 33. When the lead screw 31 rotates, the nut seat 33 will drive the positioning seat 2 connected above to move linearly along the guide groove 11.

[0024] As shown in Figure 1 , Figure 4 , a synchronous mechanism 4 is fixed in the geometric center of the positioning disc 1, the synchronous mechanism 4 includes a sleeve 41 vertically fixed in the geometric center of the positioning disc 1, a rotating shaft 42 is rotatably installed in the sleeve 41 through a bearing, the upper end of the rotating shaft 42 extends out of the sleeve 41 and is fixedly connected with a first bevel gear 43. Each lead screw 31 is provided with a second bevel gear 44 near one end. All the second bevel gears 44 are meshed with the central first bevel gear 43 to form a bevel gear transmission network.

[0025] Preferably, a slot 421 is formed in the top of the rotating shaft 42. When the operator rotates the central rotating shaft 42 with a tool, the first bevel gear 43 rotates synchronously, and synchronously drives all the second bevel gears 44 meshed therewith to rotate synchronously, driving all the lead screws 31 to rotate synchronously, and further driving all the nut seats 33 to move synchronously and at a constant speed along the radial direction. Through one input action, the radial positions of all the positioning seats 2 on the circumference are adjusted synchronously, the adjustment efficiency is greatly improved, and the consistency of positioning is ensured.

[0026] As shown in Figures 1-3 , two symmetrically arranged blocking edges 111 are provided on both sides of the upper edge of the guide groove 11, which protrude inwardly. Two guide pins 34 are vertically installed on the upper end surface of the nut seat 33, and a clamping plate 7 is floatingly sleeved on the guide pins 34 through a through hole, both ends of the clamping plate 7 are located below the blocking edge 11, and the clamping plate 7 can only move up and down along the guide pins 34.

[0027] Two guide holes 211 are formed in the bottom of the bottom plate 21 of the positioning seat 2, the bottom plate 21 is sleeved on the guide pins 34 through the guide holes 211, and the guide connection between the positioning seat 2 and the nut seat 33 is realized, so that the positioning seat 2 can only move up and down along the guide pins 34. Four threaded holes 71 corresponding to the four counterbores 212 are formed in the clamping plate 7, and four threaded rods pass through the counterbores 212 from top to bottom and are connected with the threaded holes 71 of the clamping plate 7 below.

[0028] When making adjustments, first loosen the screw on the base 21. At this time, the clamp 7 separates from the stop 111. The positioning seat 2 moves synchronously with the nut seat 33 of the adjustment mechanism 3 through the guide pin 34. The precise adjustment of the position of the positioning seat 2 can be achieved through the adjustment mechanism 3.

[0029] After the positioning seat 2 is adjusted to the target position by the adjusting mechanism 3, the screws on each positioning seat are tightened in sequence. The screws pull the clamping plate 7 upward, causing it to slide upward along the guide pin 34, and finally clamp the stop 111 of the guide groove 11 together with the base plate 21. At this time, the positioning seat 2 forms a rigid connection with the stop 111 of the positioning plate 1 through the base plate 21, the clamping plate 7, and the locking force is entirely borne by the base plate 21 and the clamping plate 7, and the lead screw of the adjusting mechanism 3 no longer bears external force.

[0030] The clamping plate is floatingly mounted on the guide pin and can slide freely along the guide pin in the loosened state, ensuring that the positioning seat is not interfered with by the clamping plate during adjustment, thus ensuring easy and smooth adjustment. After the positioning seat is adjusted into place, the clamping plate is raised by the locking screw, and together with the base plate, clamps the retaining edges on both sides of the guide groove. At this time, the clamping force is fully applied to the rigid closed loop formed by the retaining edges and the clamping plate-base plate, forming a stable and reliable mechanical lock, effectively resisting vibration and cutting force during machining, and ensuring clamping rigidity.

[0031] Crucially, this structure completely isolates the locking force from the adjustment mechanism: after locking, all machining loads are directly borne by the flange, clamping plate, and base plate, without being transmitted to the lower lead screw, nut, gears, or other adjustment components. This not only prevents deformation or wear of the adjustment mechanism due to stress, thus maintaining adjustment accuracy over a long period, but also significantly extends the service life of precision transmission components, solving the common problems of mutual interference between adjustment and locking functions and difficulty in maintaining accuracy in traditional tooling.

[0032] Preferably, in order to enhance the reliability of locking, anti-slip textures are processed on the lower end face of the retaining edge 111 and the upper surface of the clamping plate 7 at the connection with the retaining edge 111 to increase friction and prevent slippage.

[0033] like Figure 7 As shown, when processing the fixed table 5, the positioning seat 2 is moved to the set position and locked by adjusting the mechanism 3. Then, the four fixed tables 5 are installed on the first mounting surface of the positioning seat 2 respectively, so that the inner ring of the fixed table 5 can be processed.

[0034] like Figure 8 As shown, when machining the swing table 6, the positioning seat 2 is moved to the set position and locked by adjusting the mechanism 3. Then, the four swing tables 6 are installed on the second mounting surface of the positioning seat 2 respectively, so that the outer ring of the swing table 6 can be machined.

[0035] The technical solutions provided in this application have at least the following technical effects or advantages: 1. By setting two mounting surfaces on the positioning seat, the clamping of the fixed table and the swing table can be adapted respectively, the design and manufacturing cost of special tooling is saved, and the tooling universality and economy are significantly improved.

[0036] 2. The quick adjustment of the positioning seat is realized through the adjusting mechanism, the locking is carried out through the clamping and locking of the positioning seat on the blocking edge, the force after locking does not pass through the adjusting mechanism, the clamping rigidity is ensured, the precision of the adjusting mechanism is protected, and the service life is prolonged.

[0037] 3. The synchronous control of multiple adjusting mechanisms is realized through the cooperation of the first bevel gear and the second bevel gear, the adjustment time is greatly shortened, and the production response speed is improved.

[0038] 4. By setting the limiting groove and the limiting pin on each mounting surface, the precise positioning of the workpiece in the horizontal and vertical directions is realized, the machining reference is ensured to be consistent, and the product machining precision and consistency are improved.

[0039] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiment are still within the scope of the technical solution of the present application.
