Description

Technical Field

[0001] The invention relates to the technical field of milling cutter machining and cutting, and in particular to a cutter handle fixed-length cutting and blanking device and process. Background Art

[0002] PCB milling cutter is a kind of milling cutter tool, also called gong cutter, which is used in the post-process of PCB (or pressing and catching the outer frame). The main purpose is to use this cutter to cut the manufactured circuit board into separate PCS or SPNL and then ship it to the customer; that is, the product size required by the customer in the end; this tool is mainly used for cutting, and the blade and force direction are in the horizontal direction, similar to the drill needle, but the force and cutting direction of the drill needle are at the drill tip, such as the existing public document CN202517099U-PCB milling cutter, which discloses a kind of the above-mentioned milling cutter;

[0003] In the production process of PCB milling cutters, in order to meet the strength of the cutter head and reduce the production cost at the same time, the cutter head and the handle are generally made of two different materials. After the cutter head and the handle are produced separately, the cutter head and the handle are connected together by welding. In the production process of the handle of the PCB milling cutter, the staff will cut the entire metal rod into a fixed length, and then grind, heat, electroplate and other processes on the end of the metal rod before the required handle is obtained. For example, the existing public document CN115401503A-A multi-angle cutting machine blanking device and the existing public document CN219665821U-A metal bar cutting and fixing device both disclose a related technical means for fixed-length cutting and blanking of metal rods. Although the technical means in the existing public documents can realize the cutting of metal rods and subsequent blanking, the existing technical means still have the following deficiencies in actual use:

[0004] 1. After the existing metal bars are cut into round steel segments (i.e., knife handles), the staff needs to manually take out the cut round steel segments and then put the round steel segments into a collection frame for collection. The operation has a low degree of automation, the entire material cutting operation is complicated and labor-intensive, and there are also certain safety hazards indirectly;

[0005] 2. During the cutting process of the existing metal rod, the metal rod needs to be clamped by a clamping mechanism, but such a clamping method cannot be applied to metal rods of different lengths and diameters, which results in poor adaptability of the entire clamping mechanism;

[0006] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the first embodiment of the present invention, and this embodiment provides a tool handle fixed-length cutting and unloading device, which cooperates with a cutting mechanism and a feeding mechanism, and the cutting mechanism and the feeding mechanism are respectively arranged on the front side of the device, and the cutting device includes wire cutting, wheel cutting or laser cutting. Before cutting, the feeding mechanism will feed the end of the metal rod to be cut to the position of the supporting mechanism 100. After the fixed length, the fixed-length mechanism 200 presses and positions the metal rod, and then the cutting mechanism cuts the metal rod. After the cutting is completed, the round steel segment is transferred and unloaded through the unloading mechanism 300. In the actual operation process, the feeding mechanism can simultaneously realize the synchronous feeding of n stacked metal rods.

[0045] Specifically, it includes a supporting mechanism 100, including a rotating disk 101, a bottom cylinder 102 coaxially arranged below the rotating disk 101, and a mounting frame 104 fixedly connected to the bottom of the bottom cylinder 102; a fixed length mechanism 200 is arranged above the rotating track body of the U-shaped placing plate 103, and the fixed length mechanism 200 and the U-shaped groove 102a are respectively arranged on both sides of the bottom cylinder 102, and the fixed length mechanism 200 includes a pressing block 201, a stop plate 202, a rectangular frame 203 and a cylinder 204; and a unloading mechanism 300 arranged on the rear side of the U-shaped groove 102a, including a clamping assembly 301, a U-shaped support plate 302 arranged below the clamping assembly 301, a pulling block arranged on one side below the U-shaped support plate 302, and a linkage rod 304 arranged on one side below the U-shaped support plate 302.

[0046] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a plurality of through grooves 101c are provided on the end surface of the rotating disk 101 along a circumferential array, and a U-shaped placement plate 103 is provided in the gap between the through grooves 101c. Extension plates 103a are symmetrically fixed on both sides of the upper end of the U-shaped placement plate 103, and a groove 101c-1 for placing the extension plate 103a is provided on the top surface of the rotating disk 101 at the upper end of the through grooves 101c. This arrangement is convenient for limiting the position of the U-shaped placement plate 103 on the one hand, and is convenient for the staff to replace the U-shaped placement plate 103 according to the diameter of the metal rod on the other hand. During operation, it is only necessary to take out the U-shaped placement plate 103 upwards, and the U-shaped placement plate 103 itself is convenient for the metal rod to be inserted from one end, so as to limit the lateral position of the metal rod;

[0047] A rotating shaft 101a-1 is fixedly provided in the middle of the bottom surface of the rotating disk 101, and the lower end of the rotating shaft 101a-1 is embedded in the output end of the first motor 101a, and the first motor 101a is fixedly connected to the mounting frame 104. This arrangement can realize that the rotating shaft 101a-1 drives the rotating disk 101 to rotate under the operation of the first motor 101a, so as to realize the cyclic rotation of the multiple U-shaped placement plates 103 on the rotating disk 101, so as to realize the transfer of the round steel section. A limiting groove 102d is provided on the top surface of the bottom cylinder 102 in the circumferential direction, and an arc-shaped limiting rod 101b for gap matching with the limiting groove 102d is fixedly provided on the bottom surface of the rotating disk 101 between adjacent through grooves 101c. This arrangement can guide the limiting position of the rotating disk 101 relative to the bottom cylinder 102 when in use.

[0048] Furthermore, a semicircular block 103b is integrally formed on the bottom surface of the U-shaped placement plate 103. When the inner bottom surface of the U-shaped placement plate 103 and the top surface of the rotating disk 101 are located on the same horizontal plane, the lower end of the semicircular block 103b is tangent to the bottom surface of the rotating disk 101.

[0049] See Figure 5 and Figure 6 As shown, a U-shaped groove 102a with an open upper end is provided on the side wall of the bottom cylinder 102 along the axial direction, a support block 102b is gap-fitted in the U-shaped groove 102a, and a connecting rod 102b-1 is fixedly provided on one side of the support block 102b facing the outer side of the bottom cylinder 102, a screw column 102c is spirally sleeved on the free end of the connecting rod 102b-1, the lower end of the screw column 102c is rotatably connected to the outer side wall of the bottom cylinder 102 through a rolling bearing, and a first toothed disc 102c-1 is fixedly provided on the lower end of the screw column 102c;

[0050] When the above-mentioned arrangement is in use, the first toothed disc 102c-1 is rotated to drive the screw column 102c to rotate. Due to the spiral matching arrangement between the screw column 102c and the connecting rod 102b-1, the support block 102b can be moved up and down in the U-shaped groove 102a. When the support block 102b moves to the bottom of the U-shaped groove 102a, the U-shaped placement plate 103 can be conveniently dropped into the U-shaped groove 102a to quickly clamp and take out the round steel section. When the support block 102b moves to the top of the U-shaped groove 102a, the U-shaped placement plate 103 in the U-shaped groove 102a can be ejected, which is convenient for subsequent repeated clamping and taking operations and the repeated use of the U-shaped placement plate 103.

[0051] See Figure 8 , Fig. 9 , Fig.10 and Fig.12 As shown, the clamping assembly 301 includes two symmetrical clamping plates 301a, a connecting seat 301b arranged below the clamping plate 301a and a movable plate 301c arranged below the connecting seat 301b, an extension ear 301b-5 is fixedly provided on one side surface of the connecting seat 301b, and the free end of the extension ear 301b-5 is fixedly sleeved with a second rotating column 301b-6, a second fixed ear 301c-2 for rotating connection with the second rotating column 301b-6 is fixedly provided on one side surface of the upper end of the movable plate 301c, the rear end of the second rotating column 301b-6 is fixedly connected to one end of the linkage rod 304, and the other end of the linkage rod 304 is fixedly connected to the gear column 304a, the middle part of the movable plate 301c is spirally sleeved with a screw rod 302b, and the screw rod 302b Both ends are rotatably connected to the U-shaped support plate 302 through rolling bearings, and the movable plates 301c at both ends of the screw rod 302b are symmetrically slidably sleeved with guide rods 302a, and both ends of the guide rod 302a are fixedly connected to the end plates of the U-shaped support plate 302. When this arrangement is in use, the setting of the guide rod 302a can play a role of limiting and guiding the movement of the movable plate 301c, and the rear end of the screw rod 302b passes through the U-shaped support plate 302 and is embedded in the output end of the second motor 302b-1, and the screw rod 302b at the rear of the U-shaped support plate 302 is fixedly sleeved with a third toothed disc 302b-2 meshing with the gear column 304a, the second motor 302b-1 is fixedly connected to the U-shaped support plate 302, and the U-shaped support plate 302 is fixedly connected to the mounting frame 104;

[0052] When the above arrangement is in use, the second motor 302b-1 can be used to rotate the screw rod 302b. Because the screw rod 302b and the movable plate 301c are screw-fitted, the movable plate 301c can reciprocate in the axial direction of the screw rod 302b. Under the action of the reciprocating motion, the clamping assembly 301 can repeatedly clamp, transfer and cut the round steel segment.

[0053] When the movable plate 301c moves along the axis of the screw rod 302b, the linkage rod 304 will also move synchronously. When the gear column 304a on one end of the linkage rod 304 engages with the third gear disc 302b-2, the second motor 302b-1 drives the third gear disc 302b-2 to rotate, and the linkage rod 304 drives the connecting seat 301b to rotate with the second rotating column 301b-6 as the axis, so that the round steel segment can be unloaded after reaching the predetermined position.

[0054] Furthermore, a pulling plate 303 is fixedly provided on the bottom surface of the movable plate 301c, and a second tooth 303a meshing with the first toothed disc 102c-1 is provided on one side surface of the free end of the pulling plate 303 in the direction of the long side, and a guide groove 302c for the pulling plate 303 to slide through is provided on the bottom plate of the U-shaped support plate 302 in the direction of the long side. When this arrangement is in use, when the movable plate 301c moves along the axial direction of the screw rod 302b, the pulling plate 303 will also rotate synchronously. Because of the meshing arrangement between the second tooth 303a on the pulling plate 303 and the first toothed disc 102c-1, during the movement of the movable plate 301c, the reciprocating motion of the support block 102b in the vertical direction can be realized.

[0055] Furthermore, a first magnetic plate 301c-1 is embedded and fixed on the top surface of the movable plate 301c. The setting of the first magnetic plate 301c-1 can adsorb the connecting seat 301b, so as to improve the stability of transportation when transporting the round steel segment.

[0056] In addition, if it is necessary to explain, the device also includes a controller (not shown in the drawings), which is used to control the electrical components in the device. Example 2

[0057] Reference Figure 1 , Figure 4 and Figure 7 , which is the second embodiment of the present invention, is based on the previous embodiment, except that, in order to facilitate the clamping and cutting of round steel segments of different lengths, the specific structure of the fixed-length mechanism 200 is described in detail for better implementation.

[0058] Specifically, the pressing block 201 is used to cooperate with the inner clearance of the U-shaped placing plate 103, and a first convex groove 201b is opened at one end of the pressing block 201 close to the center of the rotating disk 101, and a first T-shaped rod 201a is gap-fitted in the first convex groove 201b, and a sliding block 201a-1 is fixed on one end of the first T-shaped rod 201a extending to the outside of the pressing block 201, and a first spring 201c is slidably sleeved on the first T-shaped rod 201a located inside the first convex groove 201b. The arrangement of the first spring 201c can realize the return of the first T-shaped rod 201a. A first sliding groove 202a with an open lower end for the clearance fit of the sliding block 201a-1 is provided on one side surface of the push plate 202 along the long side direction. This setting can realize the free sliding of the sliding block 201a-1 in the first sliding groove 202a, so that when the pressing block 201 moves down for clamping, the push plate 202 can keep its position unchanged; a cylinder 204 is fixedly provided in the middle of the top surface of the pressing block 201, and the fixed section of the cylinder 204 is fixedly sleeved on the horizontal plate below the rectangular frame 203, and the horizontal plate above the rectangular frame 203 is fixedly connected to the mounting frame 104;

[0059] When the above arrangement is in use, when the metal rod to be cut is inserted from one end of the U-shaped placing plate 103, the end of the metal rod will abut against one side surface of the abutment plate 202. Through the sliding arrangement of the first T-shaped rod 201a in the first convex groove 201b, the abutment plate 202 can move in the axial direction of the first T-shaped rod 201a, so that the cutting of round steel segments of different lengths can be achieved. When the length of the metal rod inserted into the U-shaped placing plate 103 reaches a predetermined length, the cylinder 204 will extend to drive the pressure block 201 to move downward to clamp the metal rod.

[0060] The two side walls of the first sliding groove 202a are symmetrically provided with positioning grooves 202a-1, and the side walls of the sliding block 201a-1 are fixedly provided with positioning strips 201a-2 for loosely fitting with the positioning grooves 202a-1. This arrangement can serve as a limit guide for the movement of the sliding block 201a-1 in the first sliding groove 202a; the top surfaces of the pressing blocks 201 on both sides of the cylinder 204 are symmetrically fixed with second T-shaped rods 201d, and the second T-shaped rods 201d are slidably sleeved on the horizontal plate below the rectangular frame 203. This arrangement can serve as a limit guide for the movement of the cylinder 204. Example 3

[0061] Reference Figure 8 , Fig. 9 , Fig.10 and Fig.12 , which is the third embodiment of the present invention, is based on any of the above embodiments, except that, in order to facilitate rapid clamping and transportation of round steel segments with different diameters, the structure of the clamping assembly 301 is described in detail.

[0062] Specifically, a convex block 301a-1 is fixedly provided on the bottom surface of one of the clamping plates 301a, and a first fixed ear 301a-2 is fixedly provided on the bottom surface of the other clamping plate 301a. A first rotating column 301a-3 is fixedly sleeved in the first fixing ear 301a-2. This arrangement can realize that the first fixing ear 301a-2 rotates around the first rotating column 301a-3, and a second toothed disc 301a-4 is fixedly provided on one end of the first rotating column 301a-3. A second sliding groove 301b-2 for clearance fitting of the convex block 301a-1 is provided on the top surface of the connecting seat 301b, and the second sliding groove 301b-2 is close to the extension ear 301b-5. A mounting groove 301b-1 for placing the first fixed ear 301a-2 is provided on the top surface of the connecting seat 301b on the side, and both ends of the first rotating column 301a-3 are rotatably sleeved on the connecting seat 301b, and a positioning column 301b-3 is slidably sleeved on the convex block 301a-1 to achieve the limiting guide of the movement of the convex block 301a-1, and both ends of the positioning column 301b-3 are fixedly connected to the inner wall of the second sliding groove 301b-2, and a second spring 301b-4 is slidably sleeved on the positioning column 301b-3 on the side of the convex block 301a-1 close to the first fixed ear 301a-2. This arrangement can achieve automatic resetting of the convex block 301a-1;

[0063] An electromagnetic plate 301e is fixedly sleeved on a mounting plate 301e-1 fixedly connected to an outer wall of one side of the connecting seat 301b by bolts, an L-shaped rod 301d is provided on one side of the electromagnetic plate 301e, and an L-shaped plate 301a-5 is provided on the other side of the electromagnetic plate 301e. A first tooth 301d-1 meshing with the second toothed disc 301a-4 is provided on the bottom surface of the upper end cross bar of the L-shaped rod 301d along the long side direction, and the upper end of the L-shaped plate 301a-5 is fixedly connected to one of the clamping plates 301a;

[0064] A third T-shaped rod 301d-2 is symmetrically fixed on one side of the vertical rod of the L-shaped rod 301d, and the free end of the third T-shaped rod 301d-2 is slidably sleeved on the mounting plate 301e-1, and a third spring 301d-3 is slidably sleeved on the third T-shaped rod 301d-2 between the mounting plate 301e-1 and the L-shaped rod 301d. The third spring 301d-3 can reset the movement of the L-shaped rod 301d, and the third T-shaped rod 301d-2 can limit the movement of the L-shaped rod 301d.

[0065] When the above arrangement is in use, the electromagnetic plate 301e is energized to generate magnetism, and the generated magnetic force can synchronously magnetically adsorb the L-shaped rod 301d and the L-shaped plate 301a-5 respectively. When the L-shaped rod 301d is magnetically adsorbed, the L-shaped rod 301d will move laterally. Because of the meshing arrangement between the first tooth 301d-1 and the second toothed disc 301a-4, the second toothed disc 301a-4 can drive the first rotating column 301a-3 to rotate, and then the first fixed ear 301a-2 can drive one of the clamping plates 301a to rotate, and the clamping plate 301a is in a vertical state. In this way, the clamping plate 301a can be limited on one side of the round steel segment. At the same time, when the electromagnetic plate 301e adsorbs the L-shaped plate 301a-5, the other clamping plate 301a will move along the axial direction of the positioning column 301b-3. In this way, the clamping plate 301a can effectively clamp the round steel segment according to the different diameters of the round steel segment, and finally realize the clamping and transportation of the round steel segment. When the electromagnetic plate 301e is powered off, the second spring 301b-4 and the third spring 301d-3 will synchronously drive the L-shaped plate 301a-5 and the L-shaped rod 301d to reset, so that the unloading of the round steel segment after transportation can be realized.

[0066] Furthermore, the top surface of the connecting seat 301b and the top surface of the rotating disk 101 are located on the same horizontal plane. This arrangement facilitates the clamping assembly 301 to receive the round steel segment on the rotating disk 101. In actual use, after the metal rod is cut, one end of the metal rod should be reserved on the outside of the rotating disk 101 to facilitate the clamping of the clamping assembly 301. Example 4

[0067] Reference Figure 8 , Fig.11 and Fig.12 , which is the fourth embodiment of the present invention, is based on the previous embodiment, except that, in order to increase the amount of round steel segment transfer so that the staff can place multiple collection frames on one side of the U-shaped pallet 302, this embodiment is proposed.

[0068] Specifically, the linkage rod 304 includes a telescopic sleeve 304b fixedly connected to the gear column 304a at one end and a telescopic rod 304c slidably sleeved on the other end of the telescopic sleeve 304b, a rectangular block 304c-1 is fixedly arranged on one end of the telescopic rod 304c slidably sleeved in the second convex groove 304b-2 of the telescopic sleeve 304b, and a second magnetic plate 304c-2 is fixedly arranged on the other end of the rectangular block 304c-1, an electromagnetic column 304b-1 is embedded and fixedly arranged on the inner end surface of the second convex groove 304b-2, and the electromagnetic column 304b-1 and the second The side surface close to the magnet plate 304c-2 is arranged in the same manner; the rectangular block 304c-1 is gap-matched with the second convex groove 304b-2, and the arrangement of the rectangular block 304c-1 can realize the limiting of the telescopic rod 304c in the second convex groove 304b-2, so as to prevent the telescopic rod 304c from rotating relative to the telescopic sleeve 304b, and a fourth spring 304c-3 is slidably sleeved on the telescopic rod 304c located inside the second convex groove 304b-2, and the arrangement of the fourth spring 304c-3 can realize the resetting of the telescopic rod 304c;

[0069] When the above-mentioned arrangement is in use, the magnitude of the magnetic force generated by the electromagnetic column 304b-1 will change by adjusting the magnitude of the current flowing through the electromagnetic column 304b-1. In conjunction with the arrangement of the second magnet plate 304c-2, the position of one end of the telescopic rod 304c in the telescopic sleeve 304b can be adjusted. In this way, when the movable plate 301c is in different positions of the screw rod 302b, the gear column 304a can engage with the third toothed disc 302b-2. In this way, the clamping assembly 301 can transfer round steel segments to multiple parallel collection frames. Example 5

[0070] This embodiment is the fifth embodiment of the present invention, and this embodiment provides a cut-to-length cutting process for a tool handle. Specifically, the process is performed according to the following steps:

[0071] S1: n metal bars are stacked in the vertical direction, and the stacked metal bars are pushed into one of the U-shaped placement plates 103 by a feeding mechanism, where n≥1;

[0072] S2: When the pushed length reaches the predetermined length, the length-fixing mechanism 200 starts to work, the pressing block 201 is pressed on the metal rod, and then the cutting mechanism cuts the stacked metal rods from top to bottom;

[0073] S3: After the cutting is completed, the pressing block 201 is reset, and the first motor 101a is actuated to drive the rotating disk 101 to rotate, so that the metal rod moves to the position of the U-shaped groove 102a;

[0074] S4: Due to the setting of the U-shaped groove 102a, under the action of gravity, the clamping assembly 301 completes the clamping action on the cut metal rod before the U-shaped placement plate 103 falls into the U-shaped groove 102a;

[0075] S5: Then the second motor 302b-1 starts to work, and the clamping assembly 301 transports the cut metal rod along the axis direction of the screw rod 302b;

[0076] S6: When transported to the predetermined position, the gear column 304a will engage with the third gear disc 302b-2. As the second motor 302b-1 works, the connecting seat 301b rotates relative to the movable plate 301c to transfer the clamped metal rods into the pre-placed collection frame, completing the unloading of the metal rods after cutting.
