Description

Technical Field

[0001] This utility model belongs to the technical field of broaching equipment, and specifically relates to a vertical grooving machine. Background Technology

[0002] A broaching machine is a specialized machine tool that uses a specially designed broach to perform powerful linear broaching motion. Its most prominent advantage is that it can efficiently and precisely machine complex-shaped keyways or outer surfaces in a single stroke, giving it an irreplaceable advantage, especially in mass production.

[0003] The applicant previously applied for a multi-feed keyway broaching machine (publication number: CN115446381B), which includes a frame, a lifting device, a broach, a positioning mechanism, and a feeding mechanism. The lifting device is slidably mounted on the frame and can limit the workpiece. The frame is provided with a drive assembly for driving the lifting device to slide. The positioning mechanism is mounted on the frame and is used to limit the broach. The feeding mechanism is mounted on the lifting device and can adjust the feed amount of the broach. The workpiece is placed on a lifting device, which then limits its position. The broach is positioned by a positioning mechanism, oriented towards the workpiece's machining area. The feed mechanism adjusts the broach's single-pass feed rate. The drive assembly then drives the lifting device and workpiece upwards simultaneously, moving the broach relative to the workpiece for the first machining operation. Subsequently, the drive assembly drives the lifting device downwards and resets. The feed mechanism feeds again based on the previous machining operation, changing the broach's position. When the drive assembly drives the lifting device upwards a second time, the broach performs a second machining operation on the workpiece. This process is repeated until a keyway of the predetermined shape is machined into the workpiece. The workpiece only needs to be clamped once. Before the drive assembly moves upwards multiple times, the feed mechanism adjusts the broach's feed rate to complete the machining of long and deep keyways on the workpiece.

[0004] This type of broaching machine has a large tonnage and more accessories, making it suitable for machining large workpieces and thick keyways. However, the broaching depth is limited, requiring multiple back-and-forth movements of the broach. The equipment is expensive and can only be installed in factories with high ceilings. If this type of machine tool is scaled down proportionally, the positioning mechanism, feed mechanism, and drive components all need to be redesigned, and the cost will still be high. Moreover, this type of broaching operation is not directly applicable to the broaching of small workpieces. There is an urgent need to develop a low-cost broaching machine tool that is suitable for small workpieces. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a vertical grooving machine. The technical problem to be solved by this utility model is: how to adapt broaching machines to the processing of small workpieces.

[0006] The above-mentioned technical objectives of this utility model can be achieved through the following technical solutions: A vertical grooving machine includes a frame, a fixture, a slide, a broach, a feed mechanism, and a retraction mechanism. The frame has a worktable at the top, with a guide rod having a groove on the worktable. The worktable has a clearance hole for the broach to pass through. The fixture is mounted on the worktable and used to limit the workpiece. The slide is slidably connected to the frame, and a broaching drive is mounted on the frame to drive the slide. The broach includes a rotating base, a tool holder, and a cutting tool. The rotating base is rotatably connected to a rotating shaft on the slide. The lower end of the tool holder is connected to the rotating base, and the upper end of the tool holder is located within the groove and abuts against the feed mechanism. The cutting tool is mounted on the upper end of the tool holder. The feed mechanism and the retraction mechanism are spaced apart on the slide. The feed mechanism pushes the tool holder towards the workpiece, and when the feed mechanism removes its force on the tool holder, the retraction mechanism pushes the tool holder away from the workpiece.

[0007] In the aforementioned vertical grooving machine, the feed mechanism includes a slide block, a pressure bar, and a feed motor. The slide block is slidably connected to the slide plate, and a lead screw sleeve is provided inside the slide block, which contains a feed lead screw. The pressure bar is connected to the slide block, and its upper end is located inside the groove. The upper end of the pressure bar has a pressing inclined surface that abuts against the cutter bar. The feed motor is mounted on the frame, and its output end is connected to the feed lead screw via a transfer device. The feed motor is used to drive the feed lead screw to rotate.

[0008] In the aforementioned vertical grooving machine, the transfer device includes a mounting box and a guide rail. The mounting box is mounted on the slide, and a bracket is provided on the outside of the frame. The guide rail is rotatably connected to the bracket. A connecting gear and a driving gear are rotatably mounted inside the mounting box. The connecting gear and the driving gear are connected by a transmission component, and the connecting gear is slidably connected to the guide rail. The guide rail can drive the connecting gear to rotate, and the driving gear is connected to the feed screw.

[0009] In the above-mentioned vertical grooving machine, the slide and the pressure bar are connected by a guide bar, and the slide plate has an assembly groove for the guide bar to slide.

[0010] In the above-mentioned vertical grooving machine, the slide has a positioning block, the positioning block is provided with a pressure plate, the pressure plate and the positioning block cooperate to form a groove, and the side of the slide has a protruding edge located in the groove, the groove guides the slide.

[0011] In the above-mentioned vertical grooving machine, a wedge is provided on the inner side of the positioning block, and the wedge has a limiting inclined surface facing the protruding edge, and the side of the protruding edge is adapted to the limiting inclined surface.

[0012] In the above-mentioned vertical grooving machine, the retraction mechanism includes a connecting seat, a bolt, and a preload spring. The connecting seat is disposed on the rotating seat and has an oblong hole. The bolt passes through the oblong hole and is connected to the slide. The preload spring is sleeved on the bolt and applies a preload force to the connecting seat pointing towards the slide.

[0013] In the aforementioned vertical grooving machine, a tool changing mechanism is provided on the rotating base. The tool changing mechanism includes a tool holder, a screw, and a nut. The tool holder is inserted into the rotating base and has a locking groove. The inner end of the screw has a locking tongue, which slides in conjunction with a guide hole in the rotating base. The nut is rotatably mounted on the rotating base and is threadedly connected to the screw. A handle is provided on the nut.

[0014] In the aforementioned vertical grooving machine, a collection trough is provided below the workbench, and the collection trough is connected to the clearance hole.

[0015] In the above-mentioned vertical grooving machine, the fixture includes a hollow rotary divider and a clamping block. The hollow rotary divider can drive the workpiece to rotate, and the clamping block is used to clamp the upper end of the workpiece.

[0016] In summary, the beneficial effects of this utility model compared to the prior art are as follows: The worker places the workpiece on the fixture. The feed mechanism forces the tool holder to swing towards the workpiece, allowing the tool to broach the inner wall of the workpiece. Then, the broaching drive controls the slide and broach to move downwards as a whole. Before the slide moves upwards, the pressure ramp moves away from the tool holder, and the retraction mechanism pushes the broach away from the workpiece. After the slide moves upwards and resets, one broaching operation is completed. Multiple broaching operations, with the feed mechanism gradually increasing the pressure on the broach, ensure a stable feed rate for each operation, thus enabling the machining of keyways on the workpiece. Compared to existing large-tonnage broaching machines, this machine tool has a smaller overall size and requires fewer parts, effectively adapting to the keyway machining of small workpieces. When the feed mechanism releases the pressure on the tool holder, the retraction mechanism automatically pushes the tool holder away from the workpiece's machining position, ensuring that the tool does not damage the workpiece during the slide reset process, making the broaching method more efficient.

[0017] Moreover, during the lifting and lowering of the slide, the transfer device moves with the slide, and the feed motor is always located on the frame. The wire that supplies power to the feed motor does not need to move back and forth, and the connection between the wire and the feed motor is less prone to wear, which can improve the service life of the feed motor.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] A vertical grooving machine, such as Figures 1-12 As shown, the machine includes a frame 100, a fixture 200, a slide 300, a broach 400, a feed mechanism 500, and a retraction mechanism 600. The top of the frame 100 has a worktable 110, on which a guide rod 120 with a sliding groove 121 is provided. The worktable 110 has a clearance hole 111 through which the broach 400 and the feed mechanism 500 pass, and the clearance hole 111 is connected to the sliding groove 121. The fixture 200 is provided on the worktable 110 and is used to limit the workpiece 1. The slide 300 is slidably connected to the frame 100. The frame 100 is provided with a broaching drive 700 for driving the slide 300 to rise and fall.

[0022] like Figures 3-5 As shown, the broach 400 includes a rotating base 410, a tool holder 420, and a cutting tool 430. A rotating shaft 310 is provided on the slide 300. The rotating base 410 is rotatably mounted on the slide 300 via the rotating shaft 310. The lower end of the tool holder 420 is connected to the rotating base 410, so that the tool holder 420 and the rotating base 410 can rotate together around the rotating shaft 310. The upper end of the tool holder 420 is located in the slide groove 121 and abuts against the feed mechanism 500. The cutting tool 430 is mounted on the upper end of the tool holder 420. The feed mechanism 500 and the retraction mechanism 600 are spaced apart on the slide 300. The feed mechanism 500 can apply a force to the tool holder 420, causing the tool holder 420 to approach the workpiece 1. When the feed mechanism 500 removes the force applied to the tool holder 420, the retraction mechanism 600 pushes the tool holder 420 away from the workpiece 1.

[0023] like Figures 1-3As shown, specifically, the broaching drive component 700 includes a drive motor 710, a drive screw 720, and a screw sleeve 730. The drive motor 710 is mounted on the frame 100, and the drive screw 720 is rotatably mounted inside the frame 100. The end of the drive screw 720 is connected to the output end of the drive motor 710 via a belt. The screw sleeve 730 is mounted on the back of the slide 300. The drive screw 720 and the screw sleeve 730 are adapted to each other. When the drive motor 710 drives the drive screw 720 to rotate, it can drive the screw sleeve 730 and the slide 300 to rise or fall as a whole.

[0024] like Figures 5-8 As shown, the feed mechanism 500 includes a slide 510, a pressure bar 520, and a feed motor 530. The slide 510 is slidably connected to the slide plate 300. A lead screw sleeve 511 is provided inside the slide 510, and a feed lead screw 512 adapted to it is provided inside the lead screw sleeve 511. The pressure bar 520 is connected to the slide 510. The upper end of the pressure bar 520 is located in the slide groove 121 and superimposed on the back of the cutter bar 420. The upper end of the pressure bar 520 has a pressing inclined surface 521 that abuts against the cutter bar 420. The upper end of the cutter bar 420 is adapted to the pressing inclined surface 521. The feed motor 530 is mounted on the frame 100. The output end of the feed motor 530 is connected to the feed lead screw 512 through a transfer device 800. The feed motor 530 can drive the feed lead screw 512 to rotate in both forward and reverse directions. For example, when the feed screw 512 rotates in the forward direction, it drives the screw 720 sleeve 511, the slide 510, and the pressure bar 520 to move upward as a whole, so that the extrusion slope 521 moves away from the upper end of the tool bar 420, and the tool retraction mechanism 600 pushes the tool bar 420 away from the workpiece 1; when the feed screw 512 rotates in the reverse direction, it drives the screw 720 sleeve 511, the slide 510, and the pressure bar 520 to move downward as a whole, so that the extrusion slope 521 extrudes the tool bar 420 towards the workpiece 1, the tool bar 420 rotates around the rotating shaft 310, and the tool 430 can extend to the machining position, thereby realizing the push of the tool bar 420 by the feed mechanism 500; the longer the pressure bar 520 moves downward, the greater the amplitude by which the guide rod 120 is pushed out of the slide groove 121.

[0025] like Figures 2-8As shown, the transfer device 800 includes a mounting box 810 and a guide rail 820. The mounting box 810 is located at the lower end or side of the slide 300. A bracket 130 is provided on the outside of the frame 100 for the guide rail 820 to be rotatably connected. One end of the guide rail 820 is connected to the output end of the feed motor 530 via a synchronous belt. The length direction of the guide rail 820 is the same as the sliding direction of the slide 300. A connecting gear 811 and a drive gear 812 are rotatably arranged inside the mounting box 810. The connecting gear 811 and the drive gear 812 are connected by a transmission component 813. The connecting gear 811 is slidably connected to the guide rail 820, and the guide rail 820 can drive the connecting gear 811 to rotate. The drive gear 812 is connected to the feed screw 512. In this embodiment, the transmission component 813 is an intermediate gear, located between the connecting gear 811 and the driving gear 812, and all three mesh with each other. Multiple intermediate gears are arranged side-by-side to connect the connecting gear 811 and the driving gear 812, which are relatively far apart. When the connecting gear 811 rotates, it drives the intermediate gear, the driving gear 812, and the feed screw 512 to rotate synchronously. In some embodiments, the transmission component 813 is a timing belt, and the connecting gear 811 drives the driving gear 812 to rotate via the timing belt.

[0026] like Figure 7 , Figure 8 As shown, a sliding sleeve 8111 is provided inside the connecting gear 811. The sliding sleeve 8111 is adapted to the outer wall of the guide rail 820, and the sliding sleeve 8111 and the guide rail 820 are in sliding engagement, thereby ensuring that the connecting gear 811 can slide along the length direction of the guide rail 820, and the guide rail 820 can also drive the connecting gear 811 to rotate. In this embodiment, the guide rail 820 is cylindrical, and the outer wall of the guide rail 820 has a track groove 821 adapted to the sliding sleeve 8111. In at least one embodiment, the cross-sectional shape of the guide rail 820 is square.

[0027] like Figure 3 , Figure 6 , Figure 9 As shown, the slide 510 and the pressure bar 520 are connected by a guide bar 540, and the slide plate 300 has an assembly groove 320 for the guide bar 540 to slide.

[0028] like Figures 5-7 As shown, the slide plate 300 has a positioning block 330, and a pressure plate 331 is provided on the positioning block 330. The pressure plate 331 and the positioning block 330 cooperate to form a groove 332. The side of the slide 510 has a protruding edge 513 adapted to the groove 332. The groove 332 guides the slide 510 through the protruding edge 513. To increase the sliding stability of the slide 510, protruding edges 513 are provided on both sides of the slide 510. Correspondingly, two positioning blocks 330 are provided at intervals, and the number of pressure plates 331 corresponds one-to-one with the positioning blocks 330, so that each protruding edge 513 has a corresponding groove 332.

[0029] At least one positioning block 330 has a wedge 340 on its inner side. The wedge 340 has a limiting inclined surface 341 facing the protruding edge 513, such that the width of the upper end of the wedge 340 is smaller than the width of the lower end. The side of the protruding edge 513 is adapted to the limiting inclined surface 341. After the protruding edge 513 abuts against the limiting inclined surface 341, the slide block 510 is limited by the limiting inclined surface 341 and cannot continue to move downward. This ensures the sliding stroke of the slide block 510 and reduces the pressure between the lead screw sleeve 511 and the feed lead screw 512, thereby ensuring the service life of the lead screw sleeve 511 and the feed lead screw 512. Furthermore, a limiting plate 342 is provided on the lower edge of the wedge 340, which can help support the lower end of the slide block 510.

[0030] like Figure 1 , Figure 9 , Figure 11 As shown, the tool retraction mechanism 600 includes a connecting seat 610, a bolt 620, and a preload spring 630. The connecting seat 610 is located on the side of the rotating seat 410 and has an oblong hole 611. The shank of the bolt 620 passes through the oblong hole 611 and is connected to the slide plate 300. The oblong hole 611 can accommodate the bolt 620 so that the rotating seat 410 can rotate normally around the rotating shaft 310. The preload spring 630 is sleeved on the bolt 620. One end of the preload spring 630 abuts against the connecting seat 610, and the other end abuts against the head of the bolt 620, so that the preload spring 630 applies a preload force to the connecting seat 610 pointing towards the slide plate 300, and the rotating seat 410 can rotate in the direction of the slide plate 300. The back of the tool bar 420 abuts against the pressure bar 520. In this embodiment, two retraction mechanisms 600 are provided, and the two retraction mechanisms 600 are distributed on both sides of the rotating seat 410 to improve the rotational stability of the rotating seat 410.

[0031] like Figures 9-12As shown, a tool changing mechanism 900 is provided on the rotating base 410, which is connected to the tool holder 420. Specifically, the tool changing mechanism 900 includes a tool holder 910, a screw 920, and a nut 930. The tool holder 910 is inserted into the rotating base 410 and is connected to the lower end of the tool holder 420. The tool holder 910 has a locking groove 911. The inner end of the screw 920 has a locking tongue 921 that matches the locking groove 911. The locking tongue 921 is slidably engaged with the guide hole 411 in the rotating base 410. The nut 930 is rotatably mounted on the rotating base 410 and is threadedly engaged with the outer end of the screw 920. The nut 930 has a handle 931. Rotating the nut 930 by the handle 931 drives the locking tongue 921 to insert into and disengage from the locking groove 911. When the locking tongue 921 is inserted into the locking groove 911, the tool holder 910 is limited by the locking tongue 921, so that the tool holder 910 and the tool bar 420 cannot be disengaged from the rotating seat 410. When the locking tongue 921 is disengaged from the locking groove 911, the tool holder 910 and the tool bar 420 can be removed from the rotating seat 410 as a whole for replacement with a new tool bar 420.

[0032] like Figures 1-4 As shown, a collection trough 112 is inclinedly arranged below the worktable 110. The collection trough 112 is connected to the clearance hole 111, and the debris generated during the processing of the workpiece 1 is discharged from the collection trough 112.

[0033] The fixture 200 includes a hollow rotary divider 210 and a clamping block 220. When the processing position of workpiece 1 needs to be changed, the hollow rotary divider 210 drives workpiece 1 to rotate. The clamping block 220 is used to clamp workpiece 1 onto the hollow rotary divider 210. The clamping block 220 has a central hole 221 and a clearance hole 222 that are connected. The clamping block 220 is sleeved on the guide rod 120 through the central hole 221. The central hole 221 is adapted to the outer wall of the guide rod 120. The clearance hole 222 allows the pressure bar 520 and the broach 400 to pass through. The lower end of the clamping block 220 has a protrusion 223 that can be inserted into the workpiece 1. The protrusion 223 can abut against the inner wall of the workpiece 1, thereby ensuring that the workpiece 1 and the guide rod 120 are coaxial. The outer wall of the guide rod 120 is provided with a plurality of blind holes 122 at intervals along the length direction. A pin can be inserted into the blind hole 122 to limit the upper end face of the clamping block 220.

[0034] The working principle of this utility model is as follows: The workpiece 1 to be processed is placed on the hollow rotary divider 210, and then the clamping block 220 is pressed on top of the workpiece 1, so that the workpiece 1 and the guide rod 120 are coaxial.

[0035] Initially, the slide 300 and slide block 510 are at their highest points of travel, and the back of the tool holder 420 rests against the pressure bar 520, with the height of the tool holder 420 remaining constant. The output end of the feed motor 530 drives the guide rail 820 to rotate, causing the connecting gear 811, transmission component 813, drive gear 812, and feed screw 512 to rotate synchronously with the guide rail 820. This causes the slide block 510, guide bar 540, and pressure bar 520 to move downwards as a whole. The extrusion slope 521 then pushes the upper end of the tool holder 420 toward the workpiece 1. The tool holder 420 and rotating seat 410 rotate as a whole along the rotating shaft 310 in a direction away from the guide rod 120. The preload spring 630 is compressed by the head of the connecting seat 610 and bolt 620. At this time, the tool 430 is in the broaching position, completing the adjustment of the feed amount of the broach 400 by the feed mechanism 500.

[0036] Afterwards, the output of the drive motor 710 drives the drive screw 720 to rotate, causing the screw sleeve 730, slide 300, broach 400, feed mechanism 500, and retraction mechanism 600 to move downwards as a whole, while the guide rod 120 remains stationary. The tool 430 can then broach the inner wall of the workpiece 1. Before the slide 300 moves upwards and resets, the output of the feed motor 530 rotates in the opposite direction, causing the guide rod 120 to drive the feed screw 512 to rotate in the opposite direction. The slide 510 and pressure bar 520 can then move upwards as a whole, pressing the inclined surface 521 away from the upper end of the tool holder 420, and the preload spring 630 resets, causing the upper end of the tool holder 420 to move away from the workpiece 1, and the retraction of the broach 400 is completed. The drive motor 710 then drives the slide 300 to move upwards and reset. The broach 400 will not interfere with the workpiece 1 or the fixture 200, and the single broaching of the workpiece 1 by the broach 400 is completed.

[0037] When the broach 400 performs broaching again, the feed mechanism 500 will gradually increase the squeezing amount on the broach 400, so that the feed amount of the broach 400 is stable each time. Through multiple broaching operations, the broach 400 can process a keyway of a predetermined depth on the inner wall of the workpiece 1.

[0038] During the upward and downward movement of the slide plate 300, the connecting gear 811 slides along the guide rail 820 through the sliding sleeve 8111. The feed motor 530 is always located on the frame 100, so the wire that supplies power to the feed motor 530 does not need to move back and forth, thus avoiding wear on the wire.

[0039] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
