[0002] Automotive door hinges are auxiliary door accessories that provide support for the door, ensuring its smooth opening and closing.

[0003] Most automotive door hinges are formed by stamping, so after stamping, excess parts need to be removed. Existing cutting methods, such as the high-precision edge-cutting device for processing automotive door hinges disclosed in patent document CN218049849U, use a cylinder to drive the cutter downwards for cutting. This method is not only inefficient, but also has low precision in the cutting position, easily generating waste. Therefore, it is necessary to design an automated device, which requires a corresponding cutting device. Utility Model Content

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] See Figures 1-7 A workpiece cutting device includes a turntable unit 1 and a double-sided cutting unit 3.

[0027] The turntable unit 1 includes a first drive unit, a turntable 11 driven by the first drive unit to rotate, and several turntable fixtures 6 mounted on the turntable 11. As one option, the first drive unit and the turntable 11 can be hydraulic turntables. Of course, the first drive unit can also be a motor, which drives the turntable 11 to rotate. To make the turntable unit more aesthetically pleasing, a housing 12 can be further provided to hide the first drive unit inside. The turntable 11 is arranged above the housing 12. The housing 12 must be designed to ensure that it does not affect the normal rotation of the turntable.

[0028] As one embodiment, it also includes a base 13, on which the bottom of the turntable unit 1 is mounted. For example, the outer casing 12 or the first drive unit is mounted on the base 13. Furthermore, it can be mounted in the middle position of the base 13 to reserve space on the base 13 for mounting other devices.

[0029] In this embodiment, four turntable fixtures 6 are installed on the upper side of the turntable 11. The four turntable fixtures 6 are evenly distributed so that when the turntable 11 rotates a quarter circumference angle (90 degrees), the turntable fixtures 6 can accurately move to the next process step. As for how to control the turntable to stop after rotating a quarter circumference angle and to restart rotating a quarter circumference angle after the corresponding workstation is completed, the electrical control method can refer to existing designs, such as designing relevant sensors, controllers, etc.

[0030] like Figure 1 As shown, the feeding machine is located at station one, the double-sided cutting unit 3 is located at station two, the single-sided cutting unit is located at station three, and the material-rolling mechanism is located at station four. Four rotary fixtures 6 correspond to their respective stations. After the rotary fixture 6 picks up material from the feeding machine and rotates 90 degrees, it stops at station two, and this cycle repeats. The above description provides a general understanding of the entire automated equipment. This embodiment focuses on the double-sided cutting unit 3 in detail; the structures of the other devices are irrelevant to this application.

[0031] For turntable fixture 6, such as Figure 3As shown, it includes a turntable fixture housing 61 and a clamping unit mounted on the turntable fixture housing 61. Specifically, the clamping unit includes a first chuck 62 fixed to the turntable fixture housing 61 and a second chuck 63 slidably disposed on the turntable fixture housing 61. The second chuck 63 is controlled by a driving member disposed on the turntable fixture housing 61 to control its longitudinal movement. As one option, the driving member can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, an oil cylinder, etc. The driving member can be specifically mounted on... Figure 3 The location shown is point A.

[0032] The second chuck 63 can be mounted on the slider, which is slidably connected to the slide rail. Two slide rails can be arranged longitudinally and are parallel to each other. The slide rails are fixed to the inner wall of the turntable fixture housing 61, thereby realizing the sliding connection of the second chuck 63.

[0033] In this embodiment, the clamping surface of the outer end of the first chuck 62 is adapted to the shape of the lower surface of the material, and the clamping surface of the outer end of the second chuck 63 is adapted to the shape of the upper surface of the material, so as to improve the clamping firmness of the material and not damage the material surface.

[0034] In this embodiment, as Figure 2 As shown, the outer side plate 611 of the turntable fixture housing 61 is provided with a through hole 612 for the outer ends of the first chuck 62 and the second chuck 63 to extend to the outside of the turntable fixture housing. The through hole 612 is reserved with space for the second chuck 63 to move longitudinally. Thus, while hiding most of the internal structure of the turntable fixture housing 61, the normal operation of the turntable fixture is not affected.

[0035] For double-sided cutting unit 3, such as Figures 4-6 As shown, it includes a second bracket 31, on which a plurality of longitudinally arranged guide columns 32 are mounted. A first body 33 is slidably arranged on the guide columns 32. A second drive unit 34 and a first reducer that is connected to the second drive unit 34 are arranged on the first body 33. Two saw blades 7 are arranged at intervals from left to right on the output shaft of the first reducer. The two saw blades 7 rotate synchronously.

[0036] In one embodiment, a first reducer is disposed inside a first machine body 33, with its output shaft extending outside the first machine body 33. A saw blade 7 is mounted at the outer end of the output shaft. A side plate 331 of the first machine body 33 extends from one side of the second bracket 31 to its outer end, and a fixing plate 332 is fixed at the outer end of the side plate 331. Figure 6 As shown, the fixing plate 332 is located on the outside of the second bracket 31. Specifically, it can be designed to be parallel to the outer facade of the second bracket 31. The second drive unit 34 is fixed on the fixing plate 332 to improve space utilization.

[0037] In this embodiment, a first drive unit 35 is also fixedly mounted on the top of the second support 31. The output end of the first drive unit 35 is connected to the first machine body 33 to control its longitudinal movement. As one implementation method, the first drive unit 35 is a servo motor, which is connected to the first machine body 33 via a ball screw and can control its up and down movement, thereby controlling the two saw blades 7 to cut from top to bottom. The material pattern after cutting at this station is as follows: Figure 7 The second material shown. After cutting, it retracts upwards and enters a pending state.

[0038] In this embodiment, the first body 33, the second drive unit 34, and the two saw blades 7 can be collectively referred to as the cutting mechanism.

[0039] After the cutting is completed at station two, the turntable rotates 90 degrees again to transfer the material to station three.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
