DETAILED DESCRIPTION

[0031] Example 1:

[0032] See also Figures 1 to 4 An embodiment of the present invention provides a cutting device for bolt production and processing, which is mainly used to ensure stable processing of threads for tapping and cutting operations in the processing of workpieces 8. The device includes a workbench 1, a tool 2, and a driving module 3 arranged on the workbench 1 and used to drive the tool 2. The driving module 3 can drive the tool 2 to move back and forth along the length direction of the workbench 1, which is a left and right movement process in this embodiment, and the driving module 3 can also drive the tool 2 to rotate to achieve tapping and cutting of the workpiece 8.

[0033] Furthermore, the workbench 1 is provided with a support assembly 4 for supporting the workpiece 8, and a guide plate 5 that is movably fitted with the support assembly 4 and is used to convey the workpiece 8. The guide plate 5 is used to convey the workpiece 8 to the support assembly 4 in sequence. When the workpiece 8 is conveyed to the support assembly 4, it automatically forms a left-right correspondence with the tool 2. At the same time, an adjustment assembly 6 that moves synchronously with the tool 2 and corresponds to the position of the support assembly 4 is also slidably mounted on the workbench 1. When the drive module 3 drives the tool 2 to move, it drives the adjustment assembly 6 to be inserted into the support assembly 4 first. At this time, the adjustment assembly 6 is used to limit and fix the workpiece 8 to prevent it from moving up and down to ensure the tapping effect. On the other hand, it can directly press against the head of the workpiece 8 to further ensure the tapping effect. Only when the adjustment assembly 6 presses against the workpiece 8 will the tool 2 contact the workpiece 8 to start the tapping operation.

[0034] Specifically, the workbench 1 is fixedly mounted with a side panel 101, to which the support assembly 4 and guide plate 5 are mounted. The side panel 101, drive module 3, tool 2, and guide plate 5 all utilize existing, mature technologies and are not described in detail here. In this embodiment, the workpiece 8 is a bolt having a head and a shank. However, this device is also suitable for machining other existing workpieces 8 having heads and shanks.

[0035] Reference Figures 2 to 4 In this embodiment, preferably, the supporting assembly 4 includes a motor 401 fixedly connected to the side plate 101, and the output shaft of the motor 401 is fixedly mounted with a disc 402 for supporting the workpiece 8, and the outer surface of the disc 402 is provided with a first receiving groove 403 and a second receiving groove 404 that are connected to each other, wherein the first receiving groove 403 is used to receive the rod portion of the workpiece 8, and the second receiving groove 404 is used to receive the head portion of the workpiece 8.

[0036] In the above structure, the tool 2 corresponds to the axial center line of the disc 402, and the first accommodating groove 403 also corresponds to the axial center line of the disc 402, so that after the workpiece 8 falls into the first accommodating groove 403 and the second accommodating groove 404, the rod of the workpiece 8 can automatically form a left-right correspondence with the tool 2, which is convenient for subsequent tapping operations.

[0037] At the same time, the first receiving groove 403 and the second receiving groove 404 also correspond to the guide plate 5. When the workpiece 8 falls from the guide plate 5, it automatically enters the disc 402 along the first receiving groove 403 and the second receiving groove 404. It should be noted that the head of the workpiece 8 remains in a vertical position while it descends along the guide plate 5 and after it falls into the disc 402, effectively preventing the workpiece 8 from rotating during the tapping operation.

[0038] Reference Figures 2 to 4 In this embodiment, preferably, the adjusting assembly 6 includes a slide plate 601 slidably mounted on the workbench 1 and moving synchronously with the tool 2, a cross bar 602 is fixedly mounted on the surface of the slide plate 601, a first telescopic rod 603 is fixedly mounted on the surface of the cross bar 602 away from the slide plate 601, a plug plate 604 corresponding to the first accommodating groove 403 is fixedly mounted on the movable end of the first telescopic rod 603, and a first spring 605 is further sleeved on the outer surface of the first telescopic rod 603, which drives the plug plate 604 to move toward the direction of the disc 402.

[0039] Among them, the plug plate 604 is adapted to the size of the first accommodating groove 403. When the plug plate 604 enters the first accommodating groove 403, it can block the exposed part above the rod of the workpiece 8; correspondingly, a semicircular groove adapted to the shape of the rod is formed at the bottom of the plug plate 604. The semicircular groove cooperates with the semicircular part of the bottom of the first accommodating groove 403 to provide effective limitation for the rod.

[0040] In the above structure, the slide plate 601 is movably mounted outside the tool 2, which can be achieved by providing an annular groove, so that when the tool 2 moves left and right, it can also drive the slide plate 601 to slide along the workbench 1, and then drive the plug plate 604 to move accordingly through the first telescopic rod 603.

[0041] During use, the workpiece 8 falls into the disc 402 through the guide plate 5 and is supported by the first receiving groove 403 and the second receiving groove 404. The drive module 3 then drives the tool 2 toward the workpiece 8. The tool 2 drives the plug plate 604 into the first receiving groove 403 via the slide 601, crossbar 602, and first telescopic rod 603. When the plug plate 604 enters the first receiving groove 403, it abuts against the outer surface of the stem of the workpiece 8. After moving along the first receiving groove 403, it can abut against the head of the workpiece 8, pushing the head against the second receiving groove 404. The drive module 3 then continues to drive the tool 2. At this point, the plug plate 604 stops moving and compresses the first spring 605, causing the tool 2 to come into contact with the workpiece 8 and begin the tapping and cutting operation. After processing is completed, the tool 2 exits and the motor 401 drives the disc 402 to rotate. When the first receiving groove 403 points downward, the workpiece 8 automatically slides out due to gravity.

[0042] To sum up, through the cooperation of structures such as the disc 402, the plug plate 604, the slide plate 601 and the first receiving groove 403, effective support of the workpiece can be achieved and the workpiece can always be kept at the axial center of the support assembly during processing. At this time, the tool presses the workpiece against the center of the support assembly, which can effectively avoid the tilting and squeezing damage to the support assembly caused during processing, thereby effectively extending the service life of the disc 402 and ensuring the stability of long-term large-scale cutting operations of bolts.

[0043] At the same time, after the plug plate 604 moves into the first accommodating groove 403, it can contact the rod of the workpiece 8 to achieve upper and lower limits, preventing the workpiece 8 from moving up and down during tapping to ensure the tapping effect, and the plug plate 604 can also be against the head of the workpiece 8 to play an auxiliary clamping effect, further ensuring the reliability of the tapping effect.

[0044] Example 2:

[0045] See also Figures 1 to 8 Based on the first embodiment, considering that the rod of the workpiece 8 usually has a certain length, and after the first accommodating groove 403 supports the rod, a section of the rod is often exposed and unsupported, thereby affecting the initial processing effect of the tool 2 on the rod, there are certain limitations in use.

[0046] To this end, the disc 402 is improved: the disc 402 now includes a base 4021 fixedly connected to the output shaft of the motor 401. A second telescopic rod 4023 is fixedly mounted on the surface of the base 4021 away from the motor 401. A partition 4022 is fixedly mounted on the movable end of the second telescopic rod 4023. The first receiving slot 403 and the second receiving slot 404 are both provided on the partition 4022. When the partition 4022 and the base 4021 are fully aligned, the disc 402 in the first embodiment is formed. A second spring 4025 is sleeved on the outer surface of the second telescopic rod 4023, which in turn causes the partition 4022 to move away from the base 4021. Correspondingly, a long hole 4027 is provided on the surface of the partition 4022 for receiving the second telescopic rod 4023 and the second spring 4025.

[0047] To prevent the workpiece 8 from tilting and falling, a stopper 4024 is fixedly mounted on the surface of the base 4021 near the partition 4022. A groove 4026 is formed on the surface of the partition 4022 to accommodate the stopper 4024. When the workpiece 8 falls from the guide plate 5 into the first receiving groove 403, the head of the workpiece 8 lands on the stopper 4024, providing the same support effect as in the first embodiment. When the partition 4022 and the base 4021 are in contact, the stopper 4024 enters the groove 4026 without interference.

[0048] Furthermore, two movable assemblies 7 are symmetrically arranged on the slide 601, corresponding to the positions of the partition 4022. The two movable assemblies 7 and the adjustment assembly 6 are arranged in a triangle. The distance between the movable assemblies 7 and the partition 4022 is smaller than the distance between the tool 2 and the workpiece 8, so that the movable assemblies 7 can contact the partition 4022 before the tool 2 contacts the workpiece 8.

[0049] Reference Figures 5 to 8 In this embodiment, preferably, the moving component 7 includes a short rod 701 fixedly connected to the skateboard 601, and a third telescopic rod 702 is fixedly installed on the end of the short rod 701 away from the skateboard 601, and a pressure plate 703 is fixedly installed on the movable end of the third telescopic rod 702. The outer surface of the pressure plate 703 is sleeved with a third spring 704, and the third spring 704 makes the pressure plate 703 have a tendency to move toward the partition 4022.

[0050] The structure of the movable assembly 7 is essentially the same as that of the adjustment assembly 6 , differing in that the structure of the plug plate 604 is different from that of the pressure plate 703 . The pressure plate 703 is designed to contact and push the partition 4022 toward the base 4021 without directly contacting the rod. Furthermore, the distance between the pressure plate 703 and the partition 4022 is smaller than the distance between the tool 2 and the workpiece 8 rod, ensuring that the pressure plate 703 contacts the tool 2 first.

[0051] Furthermore, in this embodiment, the thickness dimension of the second accommodating groove 404 along the axial direction of the partition 4022 can be correspondingly reduced to a state smaller than the thickness dimension of the head of the workpiece 8, so that after the partition 4022 is against the head of the workpiece 8, the partition 4022 is in a state where it has not yet contacted the base 4021. At this time, the partition 4022 can also provide an auxiliary clamping effect for the workpiece 8 like the plug plate 604.

[0052] During use, the workpiece 8 is processed at the axial center of the disc 402 through the structures of the disc 402, the plug plate 604, and the slide 601. The working process and effect of this part are the same as those in the first embodiment and will not be repeated here. The difference is that after the workpiece 8 falls through the guide plate 5, its head falls on the stopper 4024 and its rod falls into the first receiving groove 403. Then, the drive module 3 starts to drive the tool 2 and the slide 601 toward the workpiece 8. On the one hand, the slide 601 drives the plug plate 604 into the first receiving groove 403, and on the other hand, it drives the pressure plate 703 to approach the partition 4022. When the plug plate 604 contacts the head of the workpiece 8, the pressure plate 703 begins to contact the partition 4022. At this time, the pressure plate 703 can push the partition 4022 toward the base 4021. During this process, the tool 2 contacts the rod and starts tapping, and the movement of the partition 4022 can ensure effective support for the rod and quickly avoid the tool 2; when the partition 4022 contacts the head of the workpiece 8 and no longer moves, the tool 2 can continue processing by moving again, but the pressure plate 703 will squeeze the third spring 704.

[0053] Compared with the first embodiment, through the cooperation of structures such as the partition 4022, the base 4021, the pressure plate 703 and the stop block 4024, the rod portion can be completely covered without affecting the support of the workpiece 8, so that the stability of the rod portion can be guaranteed when the tool 2 contacts and starts tapping, and the overall processing quality can be further guaranteed; and the partition 4022 can move synchronously with the movement of the tool 2, which can achieve effective avoidance of the tool 2 and avoid damage to the tool 2.

[0054] Combined with the overall design of disk 402, the spacer 4022, once positioned, can contact the head of workpiece 8, collaborating with the stopper 604 to provide auxiliary pressure on the head, further ensuring machining quality. Furthermore, because workpiece 8 is positioned at the center of disk 402, the two pressure plates 703 provide symmetrical and balanced pressure on the spacer 4022, enhancing overall stability.

[0055] Example 3:

[0056] See also Figures 1 to 10On the basis of the second embodiment, although the guide plate 5 can continuously provide the workpiece 8 to the base 4021 and the partition 4022, due to size limitations, only one workpiece 8 can be present in the first receiving groove 403 each time the workpiece is processed, and the guide plate 5 cannot effectively block the next workpiece 8, affecting the overall continuous operation.

[0057] To this end, the stopper plate 604 is improved: now its vertical length is increased and it is provided with an inclined surface, which, when contacting the next workpiece 8, pushes it to slide along the first receiving groove 403. The surface of the crossbar 602, away from the slide plate 601, is provided with an arcuate groove 607, and the fixed end of the first telescopic rod 603 is slidably mounted within the arcuate groove 607, with the virtual center of the arcuate groove 607 being concentric with the virtual center of the partition plate 4022. Furthermore, fourth springs 606 are fixedly mounted between the front and rear sides of the fixed end of the first telescopic rod 603 and the walls of the arcuate groove 607, which tend to keep the first telescopic rod 603 positioned in the middle of the arcuate groove 607.

[0058] The top of the plug plate 604 is not lower than the top of the first receiving groove 403 . When the plug plate 604 contacts the rod of the next workpiece 8 , the rod of the next workpiece 8 can be completely pushed out of the first receiving groove 403 .

[0059] During use, the disc 402, stopper plate 604, and slide plate 601 allow the workpiece 8 to be machined at the axial center of the disc 402. The spacer plate 4022, base 4021, and stopper block 4024 cooperate to completely cover the stem of the workpiece 8, ensuring stability when the tool 2 contacts and initiates tapping. The operating process and effects of this portion are identical to those of Example 2 and are not repeated here. The difference is that when the guide plate 5 conveys the workpiece 8, the next workpiece 8 may also fall into the first receiving groove 403. At this point, the next workpiece 8 is typically partially within the guide plate 5 and partially exposed. At this point, the drive module 3 activates, driving the tool 2 and stopper plate 604 toward the workpiece 8. The bottom of the stopper plate 604 contacts the lower workpiece 8 and moves along its outer surface. The top of the stopper plate 604 contacts the stem of the upper workpiece 8 (i.e., the next workpiece 8) within the first receiving groove 403, pushing the upper workpiece 8 upward along the first receiving groove 403 until it is separated from the first receiving groove 403.

[0060] When the tool 2 has completed processing, the motor 401 first drives the base 4021 and the partition 4022 to rotate. At this time, the partition 4022 drives the plug plate 604 and the first telescopic rod 603 to slide along the arc groove 607, so that the next workpiece 8 is staggered with the first receiving groove 403; then the drive module 3 drives the tool 2 and the plug plate 604 to withdraw, and the withdrawn plug plate 604 is restored to its initial position through the first telescopic rod 603 and the two fourth springs 606, and the motor 401 continues to rotate so that the first receiving groove 403 faces downward to allow the processed workpiece 8 to detach, and then rotates to the initial state to allow the next workpiece 8 to fall.

[0061] Compared to the second embodiment, the coordination of the stopper plate 604, the arcuate groove 607, and the fourth spring 606 not only provides upper and lower limits for the workpiece 8 to be processed to prevent movement, but also provides auxiliary clamping effect by contacting the head of the workpiece 8. Furthermore, it can lift the next workpiece 8 and remove it from the first receiving groove 403, preventing the next workpiece 8 from being located in the first receiving groove 403 and affecting the processing flow, thus ensuring stable and continuous operation. This overall solution, combined with the provision of the stopper plate 604, further enhances the effectiveness of the stopper plate 604, achieving the purpose of intermittent unloading, eliminating the need for the installation of other complex unloading structures and without affecting the use of the partition plate 4022 and the base 4021.
