Description

Technical Field

[0002] A broaching machine is a machine tool that uses a broach as a tool to process through holes, planes and formed surfaces of workpieces. Broaching can achieve higher dimensional accuracy and less surface roughness, with high productivity, and is suitable for batch mass production. The jaw is an important part of the machine tool. It is a mechanical device used to clamp the workpiece on the machine tool. It is a machine tool accessory that clamps and positions the workpiece by radial movement of the movable jaws evenly distributed on the jaw body. The machining accuracy of the jaw directly affects the machining accuracy of the machine tool parts. In order to increase the clamping friction of the workpiece, multiple sets of tooth grooves are generally opened on the surface of the jaw, and these tooth grooves can be quickly processed by the broaching machine.

[0032] Embodiment 1

[0033] See also Figure 1-Figure 12 The figure shows a broaching machine for processing machine tool jaws, comprising a machine body 1, a conveying mechanism 3, a broaching mechanism 4 and a dust removal mechanism 9. Two groups of dust boxes 2 are fixedly connected to the machine body 1. The conveying mechanism 3 is installed on the machine body 1 for conveying the jaws 40. The broaching mechanism 4 comprises a sliding plate 5 slidably connected to the top surface of the machine body 1 in a horizontal direction. Two groups of mounting plates 6 are slidably connected to the sliding plate 5. Both groups of mounting plates 6 are provided with multiple groups of broaching rods 7. Multiple groups of broaching teeth 8 are fixedly connected to the broaching rods 7 for driving the sliding plate 5 to slide back and forth so that the broaching teeth 8 on the mounting plates 6 on both sides perform broaching operations on the surface of the jaws 40. The dust removal mechanism 9 comprises multiple groups of cleaning teeth 10 installed on the upper side of the mounting plate 6 for driving the cleaning teeth 10 in the broaching teeth 8 in a non-working state to slide during the movement of the mounting plate 6, so as to scrape off the debris remaining in the broaching teeth 8 and collect them through the dust removal box 2.

[0034] The broaching mechanism 4 also includes a fixed block 11 fixedly mounted on the sliding plate 5, two groups of mounting plates 6 are symmetrically distributed on both sides of the fixed block 11, a plurality of mounting grooves 12 are evenly arranged on the mounting plates 6, the broaching rod 7 is plugged into the mounting grooves 12, both ends of the broaching rod 7 are rotatably connected with screws 13 threadedly connected to the mounting plates 6, the sizes of the plurality of groups of broaching teeth 8 decrease toward the side close to the fixed block 11, and the fixed block 11 is provided with an adjusting member 14 for adjusting the spacing between the mounting plates 6 on both sides to adapt to processing with jaws 40 of different widths.

[0035] The adjusting member 14 includes a rotating rod 26 rotatably connected to the fixed block 11, the rotating rod 26 passes through the mounting plates 6 on both sides, and is provided with two groups of thread grooves 27 respectively threadedly connected to the mounting plates 6 on both sides, and the thread directions of the two groups of thread grooves 27 are opposite, and multiple groups of support plates 28 are respectively fixedly connected to the mounting plates 6 on both sides, and the support plates 28 on the mounting plates 6 on both sides slide alternately with each other in the horizontal direction, and the bottom surface of the support plate 28 slides in contact with the top surface of the fixed block 11.

[0036] The conveying mechanism 3 includes two groups of driving rollers 29 installed on the body 1 for rotating operation, the outer walls of the two groups of driving rollers 29 are connected to two groups of transmission belts 30 for transmission, and multiple groups of fixed clamps 31 for clamping and conveying the claws 40 are fixedly connected to the transmission belts 30 on both sides, an electric telescopic rod 36 is fixedly connected to the body 1, and the telescopic end of the electric telescopic rod 36 is fixedly connected to a connecting block 37 fixedly connected to the bottom surface of the sliding plate 5, and a sliding groove 38 is provided on the body 1 for slidingly connecting to the outer wall of the connecting block 37 in a horizontal direction, and two groups of dust collection boxes 2 are symmetrically distributed on both sides of the transmission belt 30, and the sides of the dust collection boxes 2 on both sides are respectively fixedly connected with support blocks 39 for sliding against the sides of the transmission belt 30.

[0037] In this embodiment, the transmission belt 30 is driven by the driving roller 29 to transmit the claws 40 to be processed, which are clamped and conveyed to the position between the mounting plates 6 on both sides by the fixing clamp 31 for subsequent drawing operation. After the drawing is completed, the claws 40 to be processed are conveyed for a distance by the transmission belt 30 to be output, and the next group of claws 40 to be processed are conveyed to the designated position for drawing. This reciprocating process can achieve the purpose of automated conveying and drawing operation. The transmission belt 30 can output the processed claws 40 by releasing the fixed state of the fixing clamp 31 at the turning position.

[0038] According to the width of the claw 40, the rotating rod 26 is rotated so that the threaded grooves 27 on both sides drive the mounting plate 6 to slide and adjust on the upper side of the sliding plate 5, and the mounting plates 6 on both sides drive the supporting plates 28 to perform staggered adjustment without affecting the support of the bottom surface of the claw 40. The mounting plates 6 drive the baffles 15 on both sides to adjust and slide, so that the spacing between the baffles 15 on the mounting plates 6 on both sides is exactly the width of the claw 40, and the broaching rod 7 of the required size is installed in the mounting groove 12 and fixed by the screws 13. Starting the electric telescopic rod 36 can drive the connecting block 37 to slide in the sliding groove 38, thereby driving the sliding plate 5 to slide along the surface of the body 1, and the mounting plates 6 on both sides drive the broaching teeth 8 to slide back and forth, and the size of the broaching teeth 8 gradually increases toward both ends, thereby realizing the broaching function of the tooth groove of the claw 40.

[0039] It is worth noting that: through the design of the two sets of mounting plates 6, the broaching rods 7 on both sides can broach the bottom surface of the claw 40 during the reciprocating sliding process, so that the broached tooth grooves are more symmetrical, avoiding the unilateral offset texture that occurs in traditional unidirectional broaching. At the same time, by adjusting the positions of the baffles 15 on both sides, the claw 40 is stably clamped in the position between the baffle 15 and the fixing clamp 31 during the broaching process. The transmission belts 30 on both sides of the claw 40 are resisted by the support blocks 39 during the broaching process, avoiding the offset during the broaching process. After the broaching is completed, the electric telescopic rod 36 is controlled to reset to the specified position, so that the claw 40 corresponds to the gap between the baffles 15 on both sides again, and the processed claw 40 can be output through the transmission belt 30.

[0040] During the movement of the mounting plate 6, the cleaning teeth 10 in the broaching teeth 8 that are not in operation are driven to slide by the dust removal mechanism 9, and the debris remaining in the broaching teeth 8 is scraped off and then collected by the dust box 2. The device has a stable structure, and two sets of symmetrical broaching rods 7 are provided for alternating broaching, which can improve the processing efficiency and automatically clean and dust the broaching teeth 8 that are in operation without affecting the continuous operation of the equipment, thereby extending the service life of the equipment and making the processing accuracy more stable.

[0041] Embodiment 2

[0042] See also Figure 2-Figure 10, this embodiment further illustrates the first embodiment, the dust removal mechanism 9 shown in the figure also includes a baffle 15 fixedly mounted on both sides of the mounting plate 6, a first slide groove 16 is provided between adjacent broaching teeth 8 on the broaching rod 7, a plurality of second slide grooves 17 connected to the first slide groove 16 are evenly provided on the upper side of the mounting plate 6, a sliding rod 18 is slidably connected in the first slide groove 16 and the second slide groove 17 in the horizontal direction, the bottom of the cleaning tooth 10 is fixedly connected to the sliding rod 18, the side surface of the cleaning tooth 10 can slide and fit with the broaching teeth 8 on both sides, and a control member 19 is provided on the machine body 1 for controlling the sliding state of the sliding rods 18 on both sides in linkage when the sliding plate 5 moves.

[0043] The control member 19 includes a connecting plate 20 installed on the upper side of the body 1, one end of the multiple sets of sliding rods 18 passes through a side baffle 15 and is fixedly connected to the connecting plate 20, a fixing plate 21 is fixedly connected to the bottom of the connecting plate 20, and a guide block 22 is fixedly connected to the bottom of the fixing plate 21. A horizontal groove 23 and an oblique groove 24 that can be slidably connected to the outer wall of the guide block 22 are provided on the body 1, one end of the horizontal groove 23 is connected to one end of the oblique groove 24, and a shielding member 25 is provided on the body 1 for shielding the upper openings of the horizontal groove 23 and the oblique groove 24 during the sliding process of the guide block 22.

[0044] The shielding member 25 includes a shielding block 34 fixedly mounted on the side of the mounting plate 6, and a guide groove 35 is provided on the shielding block 34 and is slidably connected to the outer wall of the guide block 22. The bottom surface of the fixed plate 21 slides in contact with the top surface of the guide groove 35, and the fixed plate 21 passes through the mounting plate 6 and is slidably connected to the mounting plate 6 in a horizontal direction.

[0045] In this embodiment, during the broaching process, the mounting plate 6 drives the sliding rod 18 to slide horizontally with the connecting plate 20, and the guide block 22 slides in the horizontal groove 23 and the inclined groove 24. When the mounting plate 6 moves toward the bottom of the claw 40 for broaching, the guide block 22 slides in the horizontal groove 23, and the sliding rod 18 pushes the cleaning tooth 10 to insert into the baffle 15 on one side to prevent the cleaning tooth 10 from contacting the bottom surface of the claw 40 during the broaching operation. At this time, the mounting plate 6 on the other side is in a state away from the claw 40. In this state, the guide block 22 gradually slides from the horizontal groove 23 to the inclined groove 24, and the guide block 22 also slides in the guide groove 35 at the same time, so that the fixed plate 21 and the connecting plate 20 drive the sliding rod 18 to slide out to the side, and the sliding rod 18 pulls the cleaning tooth 10 to slide in the first slide groove 16 and the second slide groove 17. The side walls of the cleaning tooth 10 slide and rub against the surfaces of the broaching teeth 8 on both sides, so that the debris adhered to the surface of the broaching teeth 8 can be fully removed, and the removed debris can be sucked out through the dust box 2 above.

[0046] By setting the blocking block 34 and the fixed plate 21, the blocking block 34 will slide together with the mounting plate 6 during sliding, and the top surfaces of the horizontal groove 23 and the inclined groove 24 can always be blocked during sliding to prevent debris from falling into the horizontal groove 23 and the inclined groove 24 and affecting the sliding of the guide block 22. Similarly, by setting the fixed plate 21, the top surface of the guide groove 35 can be blocked to prevent debris from falling.

[0047] It should be noted that: when installing the broaching rod 7, the electric telescopic rod 36 is controlled to pull the mounting plate 6 on one side to one end position, and the guide block 22 slides to one end of the inclined groove 24, so that the sliding rod 18 can slide out of the first slide groove 16 and the second slide groove 17, so that the broaching rod 7 can be installed in the mounting groove 12 for fixation. Similarly, the broaching rod 7 on the mounting plate 6 on the other side can be installed.

[0048] By setting two sets of symmetrical broaching rods 7 for alternate broaching, the processing efficiency is improved, and the broaching teeth 8 in working state can be automatically cleaned and dusted without affecting the continuous operation of the equipment, thus extending the service life of the equipment and making the processing accuracy more stable.

[0049] Embodiment 3

[0050] See also Figure 7-Figure 13 The present embodiment further illustrates the first embodiment. The cleaning tooth 10 shown in the figure is provided with two sets of spring shafts 32 , and the outer walls of the two sets of spring shafts 32 are fixedly connected with cleaning brushes 33 rotatably connected to the cleaning tooth 10 .

[0051] In this embodiment, when the guide block 22 is in the horizontal groove 23, the sliding rod 18 drives the cleaning teeth 10 to be inserted into the baffle 15 on the other side, and the baffle 15 pushes the cleaning brushes 33 on both sides to flip and fold. At this time, the spring shaft 32 is in a compressed state, and when the sliding rod 18 drives the cleaning teeth 10 to slide and clean, the cleaning teeth 10 slide out from the inside of the baffle 15. Driven by the spring spring, the cleaning brushes 33 on both sides rotate to a horizontal state and unfold to the same straight line, so that the outer walls of the broaching teeth 8 on both sides can be cleaned in the process of moving with the cleaning teeth 10. After being resisted by the broaching teeth 8, the cleaning brushes 33 will be pushed to rotate around the spring shaft 32, and will not get stuck, and can also maintain a good cleaning efficiency.
