Description

Technical Field

[0001] The invention relates to the technical field of shaft processing, in particular to a clamping tool based on processing of mold shaft parts. Background Art

[0002] In the field of mold manufacturing, shaft parts are key components in the mold structure. These shaft parts usually have high-precision dimensional requirements and strict surface quality standards, and their processing quality directly affects the overall performance and service life of the mold. For example, in an injection mold, the accuracy and surface quality of shaft parts will affect the opening and closing movement of the mold, the accuracy of injection molding, and the durability of the mold. Therefore, precise processing of mold shaft parts is a crucial link in the mold manufacturing process.

[0003] According to the Chinese patent publication number CN216967563U, the patent relates to a positioning and clamping tool for processing shaft parts, including a base, two slide plates are arranged on the base at intervals and are slidably connected with the slide plates, and the interval between the two slide plates is a positioning groove; positioning and clamping mechanisms are relatively provided at both ends of the positioning groove, and the positioning and clamping mechanisms include a No. 1 piston, a No. 1 spring, a sliding rod, a No. 1 hinge rod, a No. 2 hinge element, an arc-shaped positioning plate and a No. 1 hinge element. The fixing ring forms a concentric annular structure with extremely high connection strength through multiple fixing frames and the clamping tool. At the same time, multiple circular holes are equidistantly provided on the fixing ring, and the limiting grooves provided on each circular hole correspond to the limiting blocks fixedly arranged on the push rod and cooperate with each other to limit the push rod so that the push rod is fixed relative to the threaded rod and does not rotate. Under the action of the rotation and propulsion of the thread, the rotating threaded rod can push or retract the push rod to complete the clamping or loosening of the shaft parts.

[0004] However, in the traditional processing of shaft parts, the loading and unloading of shaft parts still requires manual tightening of bolts and other fasteners for clamping, and manual tightening of bolts for removal during unloading. Especially in batch processing, manual labor is required to repeatedly participate in the loading and unloading work, which not only increases the workload, but also has low processing efficiency. Therefore, a clamping tool based on mold shaft parts processing is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-9 The present invention provides a technical solution: a clamping tool based on the processing of mold shaft parts, including a base 1, which is used to conveniently install the device of this case on a CNC machine tool. The loading part 4 of this case is arranged above the base 1, which is used to stack and store shaft parts and automatically unload them vertically. The feeding part 5 of this case is installed on the loading part 4, which is used to intermittently load shaft parts in sequence. The placing part 7 of this case is arranged between the loading part 4 and the base 1, which is used to continuously load and unload without stopping the machine. The feeding part 8 of this case is installed on the placing part 7, which is used to force the shaft parts to be centered and automatically convey the shaft parts. The quick clamping part 9 of this case is installed on the outer wall of the placing part 7, which is used to quickly clamp the shaft parts for processing and quickly release the clamping for unloading.

[0036] In the present invention, in order to quickly load and process the same type of shaft parts in batches, the loading part 4 of this case includes a loading box 41, and a loading cavity 42 is opened from the top to the bottom of the loading box 41. A plurality of shaft parts are continuously stacked in the loading cavity 42 for storage. Slide holes 43 are symmetrically opened on both sides of the inner wall of the loading cavity 42. A support rod 44 is installed on the top of the loading box 41. A slide plate 45 is slidably connected to the support rod 44. A pressing block 46 is installed at the bottom of the slide plate 45. A disc is fixedly connected to the top of the support rod 44. The disc and the slide plate 45 are connected to each other. A tension spring 47 is elastically connected between the two, and the tension of the tension spring 47 can always reset the slide plate 45 upward. A mounting hole is opened on the base 1, and the base 1 and the CNC machine tool workbench can be stably installed through the mounting hole. The front and back of the base 1 are fixedly connected with side panels 2, and two brackets 3 are symmetrically installed on the side panels 2 on the back of the base 1. There are triangular piles at the bottom of the brackets 3 to improve the support stability. The ends of the two brackets 3 are fixedly connected to the outer wall of the loading box 41, and the loading box 41 is fixed by the brackets 3 and is suspended.

[0037] In order to load the stored shaft parts independently in sequence, the feeding part 5 of this case includes a motor 51, which is installed on the front side of the outer wall of the loading box 41. The motor 51 is a double-axis motor. Studs 52 are connected to the output shafts on both sides of the motor 51. The two studs 52 are symmetrically arranged. Each stud 52 is threadedly sleeved with an L arm 53. The two L arms 53 are symmetrically arranged. The bottom ends of the two L arms 53 are respectively fixedly connected with baffles 54. The two baffles 54 are symmetrically arranged. The two baffles 54 are respectively slidably connected to the inner walls of the two sliding holes 43. The sides of the two baffles 54 close to each other are both section structures. The two baffles 54 are mutually When the two baffles 54 are close to each other, the cross-section can be used to extrude the shaft parts at the bottom, and the pressure can be used to force the shaft parts to rise and reset on the inner wall of the loading chamber 42. The tops of the two baffles 54 on the side away from each other are fixedly connected with a pull rope 55, and the tops of the pull ropes 55 are respectively fixedly connected to the two sides of the bottom of the slide plate 45. The pull ropes 55 do not have elastic deformation ability. Therefore, when the two baffles 54 are away from each other, the pull ropes 55 will pull the slide plate 45 vertically down. The inner wall of the loading chamber 42 is slidably connected with a plurality of shaft parts 6, and each shaft part 6 is stacked in sequence. The tops of the two baffles 54 are in contact with the bottom of the outer wall of the lowest shaft part 6.

[0038] In this embodiment, in order to realize batch loading of multiple shaft parts of the same type and realize the effects of processing and loading and unloading synchronously without stopping the machine, the material placement part 7 of this case includes a disc 71, and four material channels 72 are opened around the top of the disc 71. A shaft part 6 can be placed in each material channel 72. The four material channels 72 are connected at one end close to each other. A contact sensor 73 is installed at the bottom of the inner wall of each material channel 72. The sensor model can refer to the Omron E3JK series wireless photoelectric sensor, which is mainly used to detect the generation of electrical signals when an object is in contact or not in contact. The loading box 41 is located above the center of the disc 71, and the loading cavity 42 is aligned with one of the material channels 72. The feeding box 41 is located above the center of the disc 71, and the loading cavity 42 is aligned with one of the material channels 72. Part 8 includes a second motor 81, which is installed at the bottom of the inner wall of the connecting part of the four material channels 72. A gear 82 is sleeved on the output shaft of the second motor 81. A U-plate 83 is slidably connected to the inner wall of each material channel 72. A retaining spring 84 is installed on the two ear ends of each U-plate 83. An empty groove 85 is opened at the bottom of each U-plate 83. The empty groove 85 avoids false contact when the U-plate 83 passes through the contact sensor 73. A rack 86 is fixedly connected to the side of each U-plate 83 close to the second motor 81, and the gear 82 is meshed with each rack 86 at the same time. After the second motor 81 drives the gear 82 to rotate, it will synchronously push or pull each U-plate 83 to slide through each rack 86.

[0039] It is worth noting that in order to reduce the complexity of traditional bolt fastening and clamping, the quick clamping part 9 of this case includes a support block 91, which is installed outside one of the material channels 72 and located on the outer wall of the disc 71. A bidirectional screw 92 is rotatably connected to the support block 91. The two ends of the bidirectional screw 92 are separated from each other and extend. A rotating piece 93 is fixedly connected to both ends of the bidirectional screw 92. The rotating piece 93 on either end of the bidirectional screw 92 can drive the rod body to rotate. The outer walls of the positive and negative threads of the bidirectional screw 92 are threadedly sleeved with support arms 94, and the two support arms 94 are close to each other on one side. A clamp 95 is fixedly connected, and the clamp 95 adopts a triangular structure, which can adapt to the curvature of the outer wall of the shaft part 6 so as to stably clamp it. The outer wall of the disk 71 is fixedly connected to a limit rod 96, and the two support arms 94 are slidably sleeved on the limit rod 96. The limit rod 96 prevents the support arms 94 from shaking and being unstable when sliding. There are four quick clamping parts 9 in this case, and each quick clamping part 9 can clamp a shaft part 6. The four quick clamping parts 9 are respectively installed on the outside of the four material channels 72. The angle between every two quick clamping parts 9 is ninety degrees, and the angle between every two material channels 72 is ninety degrees.

[0040] It is worth mentioning that in order to achieve continuous processing, a frame 10 is installed on the top of the base 1, and a motor three 11 is installed in the frame 10. A rotating shaft 12 is connected to the output shaft of the motor three 11, and the end of the rotating shaft 12 is fixedly connected to the bottom center of the disk 71. The motor three 11 rotates intermittently, so that the shaft part 6 can be continuously aligned with the CNC machine tool for processing. A battery 13 and a control panel 14 are installed on the side panel 2 on the front of the base 1. The load devices involved in this case are all electrically connected to the battery 13. The motors involved in this case are all equipped with CNC encoders and brakes, and are controlled by programs with the control panel 14. Each contact sensor 73 is respectively connected to the signal between the motor two 81.

[0041] Working principle: install the base 1 on the workbench of the CNC machine tool through the mounting hole, refer to Figure 1 As shown, the feed part 5 is located at the front of the loading box 41, so after the base 1 is installed, the material channel 72 located on the left side of the loading box 41 should be aligned with the processing part of the CNC machine tool. All subsequent positions involving the processing of the shaft parts 6 are carried out on the left side. The same shaft parts 6 are inserted into the inner wall from the top of the loading cavity 42 and stacked in turn. The shaft parts 6 are dragged by the baffle 54 and will not fall. The operator needs to operate and control the device of this case on the side where the control panel 14 is located, and control the motor 1 51 to rotate the studs 52 on both sides, thereby prompting the two L arms 53 to drive the two baffles 54 away from each other. At this time, the baffle 54 moves along the slide hole 43. It slides and moves away from the inside of the loading chamber 42, thereby moving away from the shaft part 6, causing all the shaft parts 6 to descend at the same time, and causing the lowest shaft part 6 to fall into the corresponding material channel 72. At the same time, the displacement of the baffle 54 will pull the pull rope 55, and drive the slide plate 45 to descend to stretch the tension spring 47. The pressure block 46 on the slide plate 45 descends into the loading chamber 42 and presses down the uppermost shaft part 6. The pressure is transmitted to the lowermost shaft part 6, so that the lowermost shaft part 6 is forced to be squeezed into the corresponding retaining springs 84 and fixed. At the same time, the bottom surface of the outer wall of the shaft part 6 comes into contact with the contact sensor 73 at this position, thereby generating an electrical signal.

[0042] The electrical signal responds to the motor 2 81 and executes the working procedure. The gear 82 rotates with the output shaft and synchronously drives the four racks 86 to move. At this time, the four U-plates 83 move away from each other. The U-plate 83 clamping the shaft part 6 pushes the shaft part 6 out of the material channel 72 stably in accordance with the bottom surface of the inner wall of the material channel 72, and makes the end of the shaft part 6 enter between the two clamps 95 at the location. The operator only needs to rotate the rotating piece 93 to quickly make the support arm 94 drive the clamp 95 to clamp the shaft part 6. Compared with the method of disassembling and assembling bolts in traditional technology, this case is obviously more convenient and simple. The other three U-plates 83 perform empty running operations along the material channel 72.

[0043] After the U-plate 83 pushes the shaft part 6 away from the material channel 72, the shaft part 6 moves away from the contact sensor 73, and the empty slot 85 of the U-plate 83 just passes through the contact sensor 73 and does not make contact. At this time, the contact sensor 73 has no induction and executes the reset program of the motor 2 81 through an electrical signal, prompting the gear 82 to reverse and drive the rack 86 to reset, and at the same time pull the U-plate 83 to reset. At this time, the shaft part 6 clamped by the clamp 95 slides out from between the retaining springs 84, so there will be no problem of secondary contact with the contact sensor 73 during the reset of the U-plate 83. If the shaft part 6 is not clamped at this time and is still driven to reset by the retaining spring 84, a secondary contact with the contact sensor 73 will occur during the retreat of the shaft part 6, so the reset program of the motor 2 81 is terminated, and the pushing program is executed again until the shaft part 6 is correctly clamped.

[0044] During the pushing of the shaft part 6, by controlling the motor 1 51 to drive the stud 52 to reverse, the two baffles 54 can be pushed closer to each other, thereby squeezing the second shaft part 6 at the bottom of the loading chamber 42 through the cross-section to rise and continue to restore the lifting state. At this time, the tension spring 47 is not pulled by the pull rope 55, and then elastically contracts to drive the slide plate 45 to rise and reset, and prompt the pressure block 46 to leave the loading chamber 42. At this time, the operator turns on the motor 3 11 through the control panel 14, so that the rotating shaft 12 drives the disc 71 to rotate clockwise ninety degrees, thereby rotating the clamped shaft part 6 to align with the processing part of the CNC machine tool. At this time, the shaft part 6 can be processed, and at the same time, another empty material channel 72 rotates to the front of the operator to align with the loading chamber 42. At this time, the operator adds a new shaft part 6 to the top of the loading chamber 42 to ensure that the subsequent pressure block 46 can be pressed down smoothly, and then turns on the motor 1 51 and follows the above steps to load the second shaft part 6.

[0045] The above steps are adopted and so on. After the processing of the current shaft part 6 is completed, the disc 71 is rotated ninety degrees to align the next shaft part 6 to the processing part of the CNC machine tool. When the first processed shaft part 6 rotates one circle and returns to the operator, the clamp 95 can be quickly separated by rotating the bidirectional screw 92, and the processed shaft part 6 can be directly removed. This is efficient and convenient. During the processing of the previous shaft part 6, the loading or unloading work can still be performed, which reduces the work time and improves the work efficiency. A single person can handle the processing of batch shaft parts 6, while reducing the work difficulty and reducing the workload of manpower loading and unloading and supervision.
