DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The present utility model will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.
[0023] The present utility model provides a machine tool processing and bending device as shown in Figures 1-4 which includes a working platform 1 for conveying rod-shaped workpieces. One end of the working platform 1 is provided with a rotatable bending turntable 2 for bending workpieces. Installation frames 3 are arranged on both sides of the working platform 1. The installation frames 3 are located at the top of the bending turntable 2. A plurality of clamping components 8 are installed on the installation frames 3. A plurality of clamping rods 806 are arranged inside the clamping components 8. The clamping rods 806 can synchronously clamp a bending block 6 for bending workpieces. A plurality of holes for inserting the bending block 6 are opened at the top of the bending turntable 2. The bottom end of the bending turntable 2 can fix the bending block 6 placed in its hole by setting an electromagnetic chuck. The working end face size of the bending block 6 can be changed according to different requirements for its contour and diameter, so as to improve the adaptability of the bending device to the environment.
[0024] The bottom end of the installation frame 3 is detachably connected with a connecting plate 9. A plurality of second telescopic rods 5 capable of synchronously driving the connecting plate 9 to lift are installed at the top of the installation frame 3. The purpose of setting two telescopic devices is to prevent a single telescopic device from interfering with the bent workpiece during the downward movement and avoid being unable to send the bending block 6 into the specified hole.
[0025] An annular sliding groove 901 is opened at the top of the connecting plate 9. An adjusting turntable 7 is rotatably arranged at the top of the connecting plate 9. An annular sliding block 703 sliding inside the annular sliding groove 901 is arranged at the bottom end of the adjusting turntable 7. A toothed ring 701 is arranged on the outer side wall of the adjusting turntable 7. A transmission gear 702 meshing with the toothed ring 701 for driving the adjusting turntable 7 to rotate is also installed at the top of the connecting plate 9. Through the setting of the annular sliding groove 901 and the annular sliding block 703, the adjusting turntable 7 can rotate around the connecting plate 9. When the bending turntable 2 and the adjusting turntable 7 rotate synchronously, it is convenient to send the bending block 6 into the hole at the specified position, and the position of the bending block 6 can be replaced during the movement.
[0026] An expansion component mounting plate 4 is arranged at the top of the adjusting turntable 7. A plurality of independently controllable first telescopic rods 401 are arranged at the bottom end of the expansion component mounting plate 4. The bottom ends of the plurality of first telescopic rods 401 are all connected with the clamping components 8. The positions of the first telescopic rods 401 and the clamping components 8 can be corresponding to the holes on the bending turntable 2 through rotation. By independently controlling the first telescopic rods 401, the placement and clamping of the bending block 6 can be carried out synchronously, thereby improving the working efficiency.
[0027] A plurality of grooves for the longitudinal sliding of the clamping assembly 8 are provided at the bottom end of the adjusting turntable 7. The clamping assembly 8 includes an annular frame 802. The interior of the annular frame 802 is hollow, and a plurality of adjusting blocks 803 for synchronously controlling the ejection or contraction of the clamping rods 806 are slidably arranged therein. A damping block 810 for stable clamping is arranged on the inner side wall of the annular frame 802 of the clamping rod 806. The damping block 810 is used for clamping the bending block 6. A spherical head 601 for facilitating clamping is arranged at the top end of the bending block 6. The arrangement of the spherical head 601 facilitates the more firm clamping of the bending block 6 to ensure the clamping effect and avoid the situation of the bending block 6 falling off.
[0028] A second return spring 807 is arranged on one side of the clamping rod 806 located inside the annular frame 802. An extrusion slider 809 engaged with the adjusting block 803 is arranged at the end of the second return spring 807. The arrangement of the second return spring 807 facilitates the timely adjustment of the position of the extrusion slider 809 to realize the timely release of the bending block 6 and improve the response speed of the equipment.
[0029] Guide rails 804 are arranged at both ends of the adjusting block 803. A guide rod 808 is connected to the top end of the adjusting block 803. A plurality of positioning rings 801 located above the annular frame 802 are detachably installed at the top end of the adjusting turntable 7. The guide rod 808 penetrates through the annular frame 802 and extends to the outside of the positioning ring 801. A first return spring 805 is sleeved on the guide rod 808 inside the annular frame 802. The arrangements of the positioning ring 801 and the first return spring 805 are used to reduce the priority of the adjusting block 803 and avoid the premature dropping of the bending block 6. During the rising process, under the action of the first return spring 805, the adjusting block 803 applies a downward sliding force, enabling the extrusion slider 809 to clamp through the adjusting block 803 to ensure the accuracy of operation.
[0030] In this utility model, by setting a spherical head 601 at the top of the bending block 6, during use, by controlling the rotation of the adjustment turntable 7, when the position reaches the hole and matches the bending turntable 2, the connecting plate 9 is controlled by the second telescopic rod 5 to slide downward. When reaching a certain position, the annular slider 703 is ejected by the first telescopic rod 401, and the annular slider 703 slides downward. When sliding a certain distance, the guide rod 808 controls the adjustment block 803 to stop sliding, and the clamping rod 806 contracts synchronously under the action of the first return spring 805, placing the clamped bending block 6 into the hole opened at the top of the bending turntable 2, facilitating the replacement of the positions and quantities of multiple bending blocks 6 during the bending process, facilitating the generation of different bending angles and shapes through different bending combinations, thereby meeting the diverse requirements of workpiece design. Through the settings of the guide rod 808, the positioning ring 801, and the first return spring 805, it can be realized that during the ascending and descending processes, the sliding of the adjustment block 803 is behind the sliding of the annular frame 802, so as to realize clamping during the ascending process and releasing during the descending process, achieving the clamping and placement of the bending block 6. Through mechanized operation, the accuracy of positioning is ensured, the work efficiency is improved, the operation difficulty is reduced, and the reliability of product quality is ensured.
[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
