Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a multi-station rotary table for machining. Background Technology

[0002] A rotary table typically consists of a turntable body, a drive system, a transmission mechanism, a clamping device, and a control system. It needs to achieve multi-angle positioning, continuous rotation, or indexing motion, while simultaneously bearing high loads and adapting to dynamic response requirements under different working conditions. Its core objective is to provide high-precision, high-stability rotary motion for workpieces or tools in industrial manufacturing to meet the needs of complex machining, inspection, or assembly tasks.

[0003] Application No. CN202420981371.1 discloses a multi-station CNC rotary table, including a base and fixtures. A drive motor is fixedly connected to the upper surface of the base, and a turntable is rotatably connected to one side of the drive motor. A rotary table is fixedly connected to the arc surface of the turntable. An adjustment structure is provided on the upper surface of the rotary table. The adjustment structure includes four L-shaped plates. The long arms of the four L-shaped plates are fixedly connected to the rotary table, and the short arms of the L-shaped plates are threaded with screws. The four screws are arranged in pairs, and the lower end of each pair of screws is rotatably connected to a top plate. A long plate is fixedly connected to one side of the turntable. This multi-station CNC rotary table achieves the effect of adjusting the distance between multiple fixtures, solving the problem that fixtures are generally directly fixed to the rotary table, and therefore, when multiple stations are processing large parts simultaneously, the rotation of the fixtures can easily cause collisions between parts, resulting in damage.

[0004] However, the number of fixtures installed in this device is limited, and it cannot install a certain number of fixtures according to the needs, which results in a limited number of parts to be processed. In addition, the working surface of the turntable is only one side, which leads to low space utilization and limited processing efficiency. The single-sided design means that the workpiece clamping and processing process must be carried out alternately, and it is impossible to achieve multi-sided synchronous processing or parallel loading and unloading operations. Therefore, a multi-station machine machining rotary table is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a multi-station rotary table for machining.

[0006] The technical solution adopted by this utility model to solve its technical problem is a multi-station machining rotary table, including a turntable. The turntable is a cuboid structure. Each of the four sides of the turntable is provided with a sliding groove and a mounting groove. The sliding groove and the mounting groove are internally connected. The mounting groove is used for the installation and insertion of a limiting plate and a support platform. The interior of the sliding groove is used for the sliding of the limiting plate and the support platform. The bottom end of the support platform is fixedly connected to the top end of the limiting plate. A clamp is installed on the top end of the support platform.

[0007] By adopting the above technical solution, the turntable, through the through design of the slide and the mounting groove, combined with the inverted T-shaped slide structure, allows the limiting plate and the support platform to slide freely along the slide after being vertically inserted, realizing the quick installation and position adjustment of the fixture. The slots distributed at intervals on the locking strips on both sides of the slide, as well as the magnetic locking of the limiting strip, can achieve precise positioning of multiple preset workstations. This design enables the equipment to adapt to the processing needs of multiple specifications of workpieces at the same time, greatly shortening the changeover time and improving the efficiency of continuous operation of multiple processes.

[0008] The turntable adopts a cuboid structure on four sides where fixtures can be installed, which improves space utilization and enables multi-face synchronous processing or parallel loading and unloading operations.

[0009] Specifically, the turntable is fixedly connected to four sides with eight locking strips. Two locking strips are arranged in pairs opposite each other on both sides of the slide groove. The top of each locking strip has a slot, and there are multiple slots.

[0010] By adopting the above technical solution, the card strips are distributed parallel to both sides of the slide groove to form a positioning reference. When the support table slides to the target position, the operator can achieve precise positioning through the cooperation of the card slot and the limit strip. The interval arrangement of multiple sets of card slots provides multiple preset fixing points for the fixture, which makes it easy to quickly select the work station according to the processing requirements.

[0011] Specifically, rotating seats are fixedly connected to both sides of the support platform. One end of the rotating seat is rotatably connected to a limiting strip via a rotating shaft. The limiting strip is adapted to the slot and magnetically connected.

[0012] By adopting the above technical solution, after adjusting the position of the support platform, the limiting strip can be manually rotated from the vertically retracted state to the horizontally unfolded state, so that the limiting strip is embedded in the corresponding slot. The magnetic connection design allows the limiting strip and the slot to automatically attract and lock, preventing displacement caused by processing vibration, while retaining the convenience of manually disconnecting the connection.

[0013] Specifically, the bottom end of the limiting plate is provided with pulleys, and the pulleys are provided in multiple places.

[0014] By adopting the above technical solution, the pulley contacts the bottom of the groove, and the rolling friction greatly reduces the resistance when the support platform moves, so that the operator can adjust the position of the clamp with just a light push.

[0015] Specifically, both ends of the turntable are fixedly connected to turntables, one of which is rotatably mounted on one side of the drive motor, and the drive motor is fixedly mounted on the top surface of the base.

[0016] By adopting the above technical solution, the drive machine drives the turntable to rotate as a whole through the turntable, causing the clamps on all four sides to change direction synchronously.

[0017] The beneficial effects of this utility model are:

[0018] (1) The multi-station machining rotary table of this utility model has a through design of sliding groove and mounting groove, combined with an inverted T-shaped sliding groove structure, which allows the limiting plate and support table to slide freely along the sliding groove after being vertically inserted, so as to realize the quick installation and position adjustment of the fixture. The slots distributed at intervals on the card strips on both sides of the sliding groove, as well as the magnetic locking of the limiting strip, can realize the precise positioning of multiple preset stations. This design enables the equipment to adapt to the processing needs of multiple specifications of workpieces at the same time, greatly shortening the changeover time and improving the efficiency of continuous operation of multiple processes.

[0019] (2) The multi-station machining rotary table of this utility model adopts a cuboid structure on four sides where fixtures can be installed, which improves the space utilization and realizes multi-face synchronous processing or parallel loading and unloading operation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As one embodiment of this utility model, such as Figures 1-3 As shown, the multi-station machining rotary table of this utility model includes a turntable 4, which is a cuboid structure. Each of the four sides of the turntable 4 is provided with a sliding groove 5 and a mounting groove 6. The sliding groove 5 and the mounting groove 6 are internally connected. The mounting groove 6 is used for the installation and insertion of a limiting plate 11 and a support platform 7. The interior of the sliding groove 5 is used for the sliding of the limiting plate 11 and the support platform 7. The bottom end of the support platform 7 is fixedly connected to the top end of the limiting plate 11. A clamp 8 is installed on the top end of the support platform 7.

[0027] In use, the limiting plate 11 and the support table 7 can be directly inserted vertically into any surface of the turntable 4 through the mounting slot 6, and then slid horizontally along the slide 5 to the target position. The guiding effect of the slide 5 ensures that the support table 7 and the fixture 8 remain stable during movement, and the open design of the mounting slot 6 facilitates quick loading and unloading of fixture components, adapting to multi-station processing needs.

[0028] It should be noted that the cross-section of the slide groove 5 is set with an inverted T-shaped structure, so that the limiting plate 11 can be locked inside the slide groove 5.

[0029] The present invention also includes that the four sides of the turntable 4 are fixedly connected with the locking strips 10, there are eight locking strips 10, two locking strips 10 are arranged in a group opposite each other on both sides of the slide groove 5, and the top of the locking strip 10 is provided with a locking groove 9, and there are multiple locking grooves 9.

[0030] When in use, the locking strips 10 are distributed parallel to both sides of the slide groove 5 to form a positioning reference. When the support table 7 slides to the target position, the operator can achieve precise positioning through the cooperation of the locking groove 9 and the limiting strip 13. The multiple sets of locking grooves 9 are arranged at intervals to provide multiple preset fixing points for the fixture 8, which makes it easy to quickly select the work station according to the processing requirements.

[0031] The present invention also includes rotating seats 14 fixedly connected to both sides of the support platform 7. One end of the rotating seat 14 is rotatably connected to a limiting strip 13 via a rotating shaft. The limiting strip 13 is adapted to the slot 9 and magnetically connected.

[0032] When in use, after adjusting the position of the support platform 7, manually rotate the limiting strip 13 from the vertical storage state to the horizontal unfolded state so that the limiting strip 13 is embedded in the corresponding slot 9. The magnetic connection design allows the limiting strip 13 and the slot 9 to automatically attract and lock, preventing displacement caused by processing vibration, while retaining the convenience of manually disconnecting the connection.

[0033] It should be noted that a permanent magnet is embedded in the inner wall of the card slot 9, and the limiting strip 13 is made of ferromagnetic material.

[0034] This utility model also includes a pulley 12 at the bottom end of the limiting plate 11, and the pulley 12 has multiple locations.

[0035] When in use, the pulley 12 contacts the bottom of the slide groove 5, and the rolling friction greatly reduces the resistance when the support platform 7 moves, so that the operator can adjust the position of the clamp 8 with just a light push.

[0036] The present invention also includes that both ends of the turntable 4 are fixedly connected to turntables 2, one of which is rotatably mounted on one side of the drive motor 3, and the drive motor 3 is fixedly mounted on the top surface of the base 1.

[0037] In use, the drive motor 3 drives the turntable 4 to rotate as a whole through the turntable 2, which drives the clamps 8 on all four sides to change direction synchronously.

[0038] It should be noted that the drive unit 3 has a motor and other structures installed inside that can drive the turntable 2 to rotate.

[0039] When using this invention, if the fixture 8 needs to be installed on the surface of the turntable 4, the limiting plate 11 and the support platform 7 are inserted into the mounting groove 6. With the rolling of the pulley 12 at the bottom of the limiting plate 11, the support platform 7 can slide into the inside of the slide groove 5, so that the limiting plate 11 can be locked in the inner bottom of the slide groove 5. Even if the turntable 4 moves the fixture 8 vertically downward, the fixture 8 will not fall off. When the position of the fixture 8 needs to be adjusted, simply push the support platform 7 to move in the slide groove 5. When the position of the fixture 8 needs to be fixed, simply manually rotate the limiting strips 13 on both sides of the support platform 7, so that the limiting strips 13 rotate from a vertical state to a horizontal state and are locked in the slots 9 in the locking strips 10. At the same time, the slots 9 have a certain magnetic attraction to hold the limiting strips 13, thereby increasing the connection strength between the two. The drive motor 3 can drive the turntable 2 to rotate, and the rotation of the turntable 2 can drive the turntable 4 to rotate, so that the turntable 4 can rotate the workpiece on the fixture 8 for processing.
