Description

Technical Field

[0001] The invention relates to the technical field of tapping machines, in particular to a multifunctional tapping machine adapted to workpieces of various sizes. Background Art

[0002] The vertical universal folding arm tapping machine is a mechanical equipment that can process internal threads in the through hole of the workpiece. It is widely used in the manufacturing industry and can be used to process various metal products, such as nuts, flanges, etc. The common vertical universal folding arm tapping machine on the market consists of a workbench, a universal robotic arm, a clamp and tapping tools.

[0003] When the tapping machine processes a deeper through hole, a spiral wire will be cut out along the tool thread groove, and the spiral wire will become longer as the tapping depth increases. At the same time, the spiral wire will rotate and swing as the tool rotates, which will scratch the surrounding equipment or make it inconvenient for the operator to perform tapping, affecting the tapping efficiency.

[0004] Secondly, there are currently two ways to position the workpiece of a tapping machine. One is to position the workpiece through a threaded clamping device. Although the positioning is relatively stable, the clamping efficiency is low. The other is to place the workpiece between the limit blocks on two or three sides for positioning. The positioning efficiency is higher for workpieces of the same specification, but only the two or three sides of the workpiece are limited, and the stability is low. In addition, the positioning of workpieces of different specifications requires the replacement of the fixture, which affects the tapping efficiency.

[0005] Therefore, a multifunctional tapping machine suitable for workpieces of various sizes is proposed to solve the above problems. Summary of the invention

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a multifunctional tapping machine adapted to workpieces of various sizes, which has the following beneficial effects:

[0021] 1. The present invention sets a wire breaking protection component, and the protective cover gathers the metal wire bundles together. The longer part will pass through the circular ring disk and extend into the arc groove. The wire breaking disk and the arc groove are staggered with the wire breaking cutter on the circular ring disk, so as to cut off the longer part of the metal wire. The cut waste is splashed upward under the action of the cutting force and falls into the collection box along the arc surface of the arc groove.

[0022] 2. The present invention sets up a clamping assembly with multiple specifications, pulls the pull block outward, selects a positioning groove of appropriate specifications to the top of the jig, and then lets go. The first spring rebounds to insert the tooth buckle into the slot to complete the locking of the positioning plate. Then the workpiece is aligned with the positioning groove and placed on the jig.

[0023] 3. The present invention sets an oil spray lubrication component, and the extrusion teeth push the transmission rod, which in turn drives one side of the extrusion plate to descend and press down the pressing frame, and then the lubricating oil in the oil storage container is pumped out by the pressing frame pressure pump head, and the lubricating oil is sprayed onto the surface of the tapping tool more evenly. By using the above structure, lubricating oil is added only when the workpiece is tapped. Compared with manual refueling using an oil spray pot, this method of refueling is more uniform, does not require manpower, and is more convenient.

[0048] Specifically, positioning grooves 43 of multiple specifications are adapted to workpieces of multiple corresponding specifications; the two sides of the pull block 46 are set as arc-shaped concave surfaces, which can facilitate the operator to pull the tooth buckle 45; the first spring 48 can absorb the rotational potential energy of the gear 47 to facilitate the automatic rotation of the gear 47; when the telescopic rod 410 is extended to the longest, the top surface height of the jig frame 49 is greater than or equal to the top surface height of the positioning plate 42, and when the telescopic rod 410 is contracted to the shortest, it supports the jig frame 49, and cooperates with the positioning groove 43 to position the workpiece in all directions, thereby improving the stability of the workpiece during tapping.

[0049] Preferably, the broken wire protection assembly 5 also includes a collecting box 57 fixedly sleeved on the outer surface of the annular disk 53, and a switch plate 58 is arranged on the outer side of the collecting box 57. The switch plate 58 facilitates the collecting box 57 to collect and remove waste, and the outer surface of the broken wire disk 55 is provided with a chip collecting plate 59 for collecting waste.

[0050] Preferably, the axis lines of the protective cover 52, the annular disk 53, the wire breaking disk 55 and the collecting box 57 overlap, and the shape of the chip collecting plate 59 matches the shape of the groove portion of the radial section of the collecting box 57;

[0051] Specifically, by setting the chip collecting plate 59 , when the wire breaking disc 55 rotates, the chip collecting plate 59 can scrape along the groove of the collecting box 57 , so that the cleaned waste can be concentrated at the switch plate 58 , thereby facilitating the removal of the waste from the collecting box 57 .

[0052] Preferably, the middle portion of the collecting box 57 is in the shape of a frustum that opens downward, so that the waste cut from the arc groove 56 can be gathered to the outside of the collecting box 57 .

[0054] Specifically, through the setting of the trapezoidal plate 412, when the active sliding positioning plate 42 switches the positioning slots 43 of different specifications, the extrusion rods 413 squeeze the trapezoidal plate 412 downward, thereby driving the mold frame 49 to descend to a height lower than the positioning plate 42, so that the mold frame 49 will not affect the sliding of the positioning plate 42, and through the setting of the two pairs of extrusion rods 413, the trapezoidal plate 412 moves up, thereby passively driving the positioning plate 42 to slide, until the two pairs of extrusion rods 413 are just stuck on both sides of the trapezoidal plate 412, so as to achieve the effect of automatically aligning the tooth buckle 45 with the slot 44 and inserting it, which is easy to operate.

[0055] Further embodiments

[0056] Please refer to Figure 1 , Figure 2 , Figure 7 , Fig. 9 and Fig.10 As shown:

[0057] The oil injection lubrication assembly 6 includes extrusion teeth 61 circumferentially arranged at equal intervals on the wire breaking disc 55, a seesaw frame 62 is fixedly installed on one side of the top of the protective frame 51, and an extrusion plate 63 is rotatably connected to the bottom of the seesaw frame 62. A pressing frame 64 is slidably connected to one side of the extrusion plate 63, and a transmission rod 65 is rotatably connected to the other side. A third spring 66 is arranged between the transmission rod 65 and the extrusion plate 63. The extrusion plate 63 is connected to the protective frame 51 through a fourth spring 67, and the fourth spring 67 is located between the seesaw frame 62 and the pressing frame 64. A pump head 68 is fixedly connected to the bottom of the pressing frame 64. An oil storage container 69 is installed on one side of the bottom of the protective frame 51, and the function of the pump head 68 is to pump out the lubricating oil in the oil storage container 69. The oil outlet of the pump head 68 is connected to the protective cover 52 through an oil injection pipe 610.

[0058] Specifically, the third spring 66 is used to drive the transmission rod 65 to automatically rebound; the pump head 68 is an existing press-type pump head.

[0059] Preferably, the outer surface of the extrusion tooth 61 is inclined, and when the extrusion tooth 61 rotates forward, the transmission rod 65 can be pushed upward.

[0060] Preferably, one side of the extrusion plate 63 near the transmission rod 65 is a closed structure, and the other side is an open structure, so that the transmission rod 65 can rotate in one direction;

[0061] Specifically, when the wire breaking disk 55 rotates forward, the transmission rod 65 is restricted by the closed side of the extrusion plate 63 and remains vertical with the extrusion plate 63. When the wire breaking disk 55 rotates reversely, the extrusion teeth 61 push the transmission rod 65 to rotate toward the open side of the extrusion plate 63, so that when the tapping tool 3 completes the tapping and rotates reversely, the oil injection will not continue to be pressed to avoid waste.

[0062] Everything in the above example works like this:

[0063] In the initial state:

[0064] Sub-process:

[0065] The following is the working process of the multi-specification clamping assembly 4 and the broken wire protection assembly 5:

[0066] When in use, the pull block 46 is pulled outward, the tooth buckle 45 is pulled out from the slot 44, and the meshing gear 47 rotates and twists the first spring 48, then the positioning plate 42 is slid, and the extrusion rod 413 drives the trapezoidal plate 412 to make the several-shaped frame 49 descend, compress the second spring 411, select the positioning slot 43 of suitable specifications to the top of the several-shaped frame 49, and then let go, and the second spring 411 rebounds to make the trapezoidal plate 412 rise, and the positioning plate 42 is driven by the extrusion rod 413 to slide to the slot 44 and align with the tooth buckle 45, and the first spring 48 rebounds to insert the tooth buckle 45 into the slot 44, completing the locking of the positioning plate 42, and then aligning the workpiece with the positioning slot 43 and placing it on the several-shaped frame 49, and the tapping tool 3 is aligned with the through hole of the workpiece and pressed down to the lowest point to perform tapping on the workpiece;

[0067] Furthermore, during the tapping process, the protective cover 52 gathers the metal wire bundles together, and as the spiral metal wire becomes longer, the longer portion will pass through the circular ring disk 53 and extend into the arc groove 56, and the wire breaking disk 55 and the arc groove 56 will rotate synchronously with the output shaft of the driving motor 2, and thus will intersect with the wire breaking knife 54 on the circular ring disk 53, thereby cutting off the longer portion of the metal wire;

[0068] Furthermore, the cut waste is splashed upward by the cutting force and falls into the collection box 57 along the arc surface of the arc groove 56. At the same time, the chip collecting plate 59 rotates forward for several turns along with the wire cutting disc 55, and then rotates reversely for several turns to accumulate the waste near the switch plate 58. After the tapping is completed, the switch plate 58 is opened to take out the waste.

[0069] Please refer to the above working process Figures 1 to 8 .

[0070] The following is the working process of the oil injection lubrication component 6:

[0071] During the tapping process, as the wire breaking disc 55 rotates forward, the extrusion teeth 61 push the transmission rod 65, thereby driving the extrusion plate 63 to deflect on the seesaw frame 62. The extrusion plate 63 rises on one side close to the transmission rod 65, and descends on the other side and presses down the pressing frame 64, and then the pump head 68 is pressed by the pressing frame 64 to pump out the lubricating oil in the oil storage container 69. In this way, through the above method, multiple extrusion teeth 61 periodically and intermittently press the pump head 68, so that the lubricating oil can be sprayed onto the surface of the tapping tool 3 more evenly.

[0072] Please refer to the above working process Figure 1 , Figure 2 , Figure 7 , Fig. 9 and Fig.10 .

[0073] Overview:

[0074] When in use, the pull block 46 is pulled outward, and the positioning groove 43 of the appropriate size is selected to the top of the several-shaped frame 49, and then the hand is released, and the first spring 48 rebounds to insert the tooth buckle 45 into the slot 44, completing the locking of the positioning plate 42, and then the workpiece is aligned with the positioning groove 43 and placed on the several-shaped frame 49, and the tapping tool 3 is aligned with the through hole of the workpiece and pressed down to the lowest point to perform tapping on the workpiece; further, during the tapping process, the protective cover 52 will gather the metal wire bundles together, and the longer part will pass through the circular ring disk 53 and extend into the arc groove 56, and the wire breaking disk 55 and the arc groove 56 will be connected with the wire breaking tool on the circular ring disk 53. 54 are staggered, thereby cutting off the longer part of the metal wire; further, the cut waste is splashed upward by the cutting force, and falls into the collecting box 57 along the arc surface of the arc groove 56. At the same time, the chip collecting plate 59 rotates forward for multiple circles along with the wire breaking disc 55, and then rotates reversely for multiple circles to accumulate the waste near the switch plate 58; during the tapping process, the extrusion teeth 61 push the transmission rod 65, thereby driving one side of the extrusion plate 63 to descend and press the pressing frame 64, and then the pump head 68 is used to pump out the lubricating oil in the oil storage container 69 through the pressing frame 64, and the lubricating oil is sprayed onto the surface of the tapping tool 3 more evenly.

The outer surface of the extrusion tooth (61) is inclined, and when the extrusion tooth (61) rotates in the forward direction, the transmission rod (65) can be pushed upward; The axis lines of the protective cover (52), the annular disk (53), the wire breaking disk (55) and the collecting box (57) overlap, and the shape of the chip collecting plate (59) matches the shape of the groove portion of the radial section of the collecting box (57); The middle part of the collecting box (57) is in the shape of a truncated cone with a downward opening, so that the waste cut from the arc-shaped groove (56) can be collected outside the collecting box (57); Trapezoidal plates (412) are fixedly mounted at both ends of the mold frame (49), the trapezoidal plates (412) being of a trapezoidal structure, and a plurality of groups of extrusion rods (413) corresponding to the number of slots (44) are arranged at the bottom of the positioning plate (42), and each group has two pairs of extrusion rods (413), and the two pairs of extrusion rods (413) are symmetrically arranged on both sides of the corresponding slots (44); When in use, the pull block (46) is pulled outward, the tooth buckle (45) is pulled out from the slot (44), and the meshing gear (47) is rotated, and the first spring (48) is twisted, and then the positioning plate (42) is slid, and the extrusion rod (413) drives the trapezoidal plate (412) to make the several-shaped frame (49) descend, compressing the second spring (411), selecting the positioning slot (43) of appropriate specifications to the top of the several-shaped frame (49), and then letting go, through the second spring (411) The trapezoidal plate (412) is rebounded to rise, and the positioning plate (42) is driven to slide to the slot (44) and aligned with the tooth buckle (45) by the extrusion rod (413) in the reverse direction, and the tooth buckle (45) is inserted into the slot (44) by the first spring (48) to complete the locking of the positioning plate (42), and then the workpiece is aligned with the positioning slot (43) and placed on the jig (49), and the tapping tool (3) is aligned with the through hole of the workpiece and pressed down to the lowest point to perform tapping processing on the workpiece; During the tapping process, the protective cover (52) gathers the metal wire bundle together. As the spiral metal wire becomes longer, the longer portion passes through the circular ring disk (53) and extends into the arc groove (56). The wire cutting disk (55) and the arc groove (56) rotate synchronously with the output shaft of the driving motor (2), and thus intersect with the wire cutting knife (54) on the circular ring disk (53), thereby cutting off the longer portion of the metal wire. The cut waste is splashed upward by the cutting force and falls into the collecting box (57) along the arc surface of the arc groove (56). At the same time, the chip collecting plate (59) rotates forward for several turns along with the wire cutting disc (55), and then rotates backward for several turns to accumulate the waste near the switch plate (58). After the tapping is completed, the switch plate (58) is opened to take out the waste. During the tapping process, as the wire breaking disc (55) rotates forward, the extrusion teeth (61) push the transmission rod (65), thereby driving the extrusion plate (63) to deflect on the seesaw frame (62). The extrusion plate (63) rises on one side close to the transmission rod (65) and descends on the other side to press down the pressing frame (64). The lubricating oil in the oil storage container (69) is then pumped out through the pressure pump head (68) of the pressing frame (64). The plurality of extrusion teeth (61) periodically and intermittently press the pump head (68), so that the lubricating oil can be evenly sprayed onto the surface of the tapping tool (3).

2. The multifunctional tapping machine adapted to workpieces of various sizes according to claim 1, characterized in that: One side of the extrusion plate (63) close to the transmission rod (65) is in a closed structure, and the other side is in an open structure, so that the transmission rod (65) can rotate in one direction.
